Objective: To evaluate the real-world safety and effectiveness of inhaled nitric oxide (INOflo ® for Inhalation 800 ppm) for perioperative pulmonary hypertension associated with cardiac surgery in Japan., Methods: This was a prospective, non-interventional, all-case, post-marketing study of pediatric and adult patients who received perioperative INOflo with cardiac surgery from November 2015-December 2020. Safety and effectiveness were monitored from INOflo initiation to 48 h after treatment completion or withdrawal. Safety outcomes included adverse drug reactions, blood methemoglobin concentrations, and inspired nitrogen dioxide concentrations over time. Effectiveness outcomes included changes in central venous pressure among pediatrics, mean pulmonary arterial pressure among adults, and the partial pressure of arterial oxygen/fraction of inspired oxygen ratio (PaO 2 /FiO 2 ) in both populations., Results: The safety analysis population included 2,817 Japanese patients registered from 253 clinical sites (pediatrics, n = 1375; adults, n = 1442). INOflo was generally well tolerated; 15 and 20 adverse drug reactions were reported in 14 pediatrics (1.0%) and 18 adults (1.2%), respectively. No clinically significant elevations in blood methemoglobin and inspired nitrogen dioxide concentrations were observed. INOflo treatment was associated with significant reductions in both central venous pressure among pediatrics and mean pulmonary arterial pressure among adults, and significant improvements in PaO 2 /FiO 2 among pediatrics and adults with PaO 2 /FiO 2  ≤ 200 at baseline., Conclusions: Perioperative INOflo treatment was a safe and effective strategy to improve hemodynamics and oxygenation in patients with pulmonary hypertension during cardiac surgery. These data support the use of INOflo for this indication in Japanese clinical practice., (© 2023. The Author(s).)

Background: Drug shortages are a common issue that healthcare systems face and can result in adverse health outcomes for patients requiring inferior alternate treatment. The United States recently experienced a national drug shortage of intravenous immunoglobulin (IVIG). Several reported strategies to address the IVIG and other drug shortages have been proposed; however, there is a lack of evidence-based methods for protocol development and implementation., Objective: To evaluate the efficacy of introducing a multidisciplinary task force and tier system of indications and to minimize adverse effects during a shortage of IVIG., Methods: Faculty members across disciplines with expertise in IVIG use were invited to participate in a task force to address the shortage and ensure adequate supply for emergent indications. A tier system of IVIG indications was established according to the severity of diagnosis, urgency of indication, and quality of supporting evidence. Based on inventory, indications in selected tiers were auto-approved. Orders that could not be automatically approved were escalated for task force review., Results: Overall, there were 342 distinct requests for IVIG during the study period (August 1, 2019 to December 31, 2019). All Tier 1 indications were approved. Of all requests, only 2.6% (9) of requests were denied, none of which resulted in adverse effects based on retrospective chart review. Seven patients who regularly receive IVIG had possible adverse effects due to dose reduction or spacing of treatment; however, each complication was multifactorial and not attributed to the shortage or tier system implementation alone., Conclusion: Implementation of a multidisciplinary task force and tier system to appropriately triage high-priority indications for limited pharmaceutical agents should be considered in health institutions faced with a drug shortage., (© 2024 Wiley Periodicals LLC.)

Background: Thalidomide has anti-inflammatory properties and has been used off-label for multiple mucocutaneous disorders, but its application in managing refractory oral mucosal diseases is unclear. This study aimed to review the efficacy and safety of thalidomide in treating various oral mucosal disorders refractory to conventional therapies., Methods: The medical records of patients who were prescribed thalidomide from 2002 through 2021 for oral mucosal disorders were reviewed. Data collected included demographic characteristics, oral mucosal disease diagnosis, treatment courses, and thalidomide dose, duration, response, and side effects., Results: Thalidomide was prescribed for 28 patients with diagnoses of recurrent aphthous stomatitis (n = 14), inflammatory oral lichenoid lesions (n = 6), traumatic ulcerative granuloma with stroma eosinophilia (n = 5), chronic radiation-induced mucositis (n = 2), and orofacial granulomatosis (n = 1). Patients were treated for a median duration of 84 days (range 2-1,582). Clinical improvement was observed in 19 of 22 patients who completed at least 1 cycle of thalidomide (86.4%), with complete resolution in 12 patients (54.5%). Adverse events occurred in 75% of patients (n = 21), with 8 requiring thalidomide discontinuation. The most common adverse events included peripheral neuropathy (42.9%), drowsiness (28.6%), and constipation (21.4%)., Conclusions: Thalidomide may be considered for the management of refractory oral mucosal disorders. Drug side effects are common and need monitoring closely during use., Competing Interests: Declaration of interest None., (Copyright © 2024 Elsevier Inc. All rights reserved.)

AimThe aim of this study is to summarize the spontaneous reports of tardive dyskinesia (TD) and extrapyramidal symptoms (EPSs) that occurred in Japan over the past decade. MethodsThe study analyzed TD and EPS cases reported in the Japanese Adverse Drug Event Report database between April 2011 and March 2021. The cases were stratified by the diagnoses of schizophrenia, bipolar disorders, and depressive disorders. ResultsIn total, 800 patients including a total of 171 TD cases and 682 EPS cases were reported in the JADER database across psychiatric diagnosis. The cases were caused by first-generation antipsychotics (FGA, TD: n = 105, EPS: n = 245) and second-generation antipsychotics (SGA, TD: n = 144, EPS: n = 598). The SGA were categorized based on Neuroscience-based Nomenclature (NbN) regarding pharmacological domain and mode of action, which were reported evenly as the offending agents. Among reported treatment and outcome in TD cases (n = 67, 37.6%) and EPS cases (n = 405, 59.3%), the relatively limited number of TD cases were reported as recovered/improved was also limited (n = 32, 47.8%) compared to those of EPS cases (n = 266, 65.7%). Some cases still had residual symptoms or did not recover fully (TD: n = 21, 31.3%, EPS: n = 77, 19.0%). CONCLUSION: Tardive dyskinesia and EPS have been widely reported in Japan over the past decade across psychiatric diagnoses and antipsychotic classes. LIMITATIONS: It is important to acknowledge the presence of reporting bias and the lack of comparators to accurately assess risks. Owing to the nature of spontaneous reporting, the estimation of prevalence is not feasible., (© 2023 The Authors.

Introduction: In recent years, highly selective reversible CDK4/6 inhibitors have been combined with aromatase inhibitors for their efficacy and ease of application in the treatment of advanced stage of hormone-responsive breast cancers. Oral use of these drugs facilitates patient compliance. However, adverse drug reactions are reported due to these drugs, in the literature. Diverse adverse reactions such as skin reactions, liver toxicity, and vitiligo with ribociclib have been reported., Case Report: In this study, we present of liver toxicity due to the use of ribociclib in a case of advanced breast cancer with metastases. It is noteworthy that the patient did not have any other concomitant disease and did not take any other medication., Management and Outcome: After the 600 mg initial dose of ribociclib, neutropenia occurred at the beginning of the therapy, the dose was reduced to 400 mg, and liver enzymes started to rise in the second month of the therapy. In the fifth month of the intermittent treatment period, liver toxicity was grade 3 ., Discussion: Liver adverse reaction occurred due to ribociclib use in the patient who had no history of any other disease. The Naranjo algorithm score was evaluated as 9. Considering the excretion of ribociclib by sulfation, cysteine conjugation, and glucuronidation, which are phase II reactions, n-acetyl cysteine (NAC) treatment (600 mg/day) was started for the patient. NAC therapy is recommended to reduce elevated liver enzymes in the case. The patient's treatment has been continuing with palbociclib for 5 months. No increase in liver enzymes was observed., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background/aim: Patients with malignant lymphoma, in a latent state of weakened immune function, are at risk of chemotherapy-induced immunosuppression and cytomegalovirus (CMV) infection. Concomitant therapy with bendamustine and rituximab or obinutuzumab intensifies immunosuppression, potentially affecting CMV onset. This study aimed to assess CMV onset differences between bendamustine monotherapy and combination therapy with rituximab or obinutuzumab using the Japanese Adverse Drug Event Report database (JADER)., Patients and Methods: A JADER analysis dataset (April 2004 to September 2022) defined CMV infection using 31 preferred term (PT) words from MedDRA 25.1J HLT "Cytomegalovirus infection (10011827)". Reporting odds ratios (ROR) calculated CMV infection signals for bendamustine monotherapy, rituximab, obinutuzumab, bendamustine+rituximab (BR), and bendamustine+obinutuzumab (GB). ROR confidence intervals exceeding 1 indicated a CMV signal. Days of CMV infection were calculated based on adverse event onset and administration start., Results: CMV signals were confirmed for monotherapy and combination therapies. CMV infection durations (median, interquartile range) were 41.0 days (23.5-69.5) for bendamustine monotherapy, 63.5 days (35.2-95.0) for BR, and 61.0 days (33.0-102.5) for GB, with cases exceeding 200 days., Conclusion: JADER analysis detected significant CMV signals for rituximab, obinutuzumab, and bendamustine. Caution may be warranted 7-9 months post-bendamustine administration, necessitating further investigation, including cell-mediated immunity suppression assessment., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Introduction: Daratumumab is a humanized IgG 1 kappa monoclonal antibody directed against CD38 used to treat myeloma. The recommended dose of daratumumab is 16 mg/kg, with no lower or upper threshold. Here, we present the first split-dose daratumumab infusion experience in a myeloma patient with morbid obesity in whom daratumumab was interrupted because of grade 3 infusion-related reaction., Case Report: A female myeloma patient with morbid obesity received a combination of chemotherapy with daratumumab because of disease relapse. The calculated dose for the first intravenous daratumumab infusion was 1840 mg/day based on the weight of the patient, which was measured as 115 kilograms. Daratumumab infusion was initiated as appropriate but needed to be stopped because of a severe sudden presentation of shortness of breath and hypoxemia., Management and Outcome: After daratumumab was stopped, premedication was repeated, and oxygen, intravenous and inhaler steroids, inhaler β2 agonists and intravenous diphenhydramine were given in repeated doses. She was monitored and followed up in the emergency critical care unit. Daratumumab treatment with a split-dose schedule was planned after she fully recovered from all signs and symptoms. The total dose was divided into two doses and was given without any complications on two consecutive days. After that, she was also able to tolerate once a week 1840 mg of daratumumab in a single day., Discussion: There is a paucity of data regarding the best practice for instituting intravenous daratumumab in patients with morbid obesity regarding the infusion rate and duration, optimal dosing, and ideal way to cope with infusion-related reactions. Our case suggests a potential role for a split-dose schedule for patients with obesity and potential dose reductions and infusion-related reactions., Competing Interests: Author ContributionsFA researched literature and wrote first draft of the case report. OGS and VK translated the case report into English and wrote the final version of the manuscript. All authors reviewed and edited the manuscript and approved the final version of the manuscript.

Immunotherapy has revolutionized the cancer treatment landscape by opening up novel avenues for intervention. As the use of immune checkpoint inhibitors (ICIs) has exponentially increased, so have immune-related adverse events (irAEs). The mechanism of irAEs may involve the direct damage caused by monoclonal antibodies and a sequence of immune responses triggered by T cell activation. Common side effects include dermatologic toxicity, endocrine toxicity, gastrointestinal toxicity, and hepatic toxicity. While relatively rare, neurotoxicity, cardiotoxicity, and pulmonary toxicity can be fatal. These toxicities pose a clinical dilemma regarding treatment discontinuation since they can result in severe complications and necessitate frequent hospitalization. Vigilant monitoring of irAEs is vital in clinical practice, and the principal therapeutic strategy entails the administration of oral or intravenous glucocorticoids (GSCs). It may be necessary to temporarily or permanently discontinue the use of ICIs in severe cases. Given that irAEs can impact multiple organs and require diverse treatment approaches, the involvement of a multidisciplinary team of experts is imperative. This review aims to comprehensively examine the pathogenesis, clinical manifestations, incidence, and treatment options for various irAEs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yan, Yu, Zhang, Chen, Fu, Tang and Liao.)

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with an increased morbidity and mortality. There is clinical evidence that an increasing number of cardiovascular and non-cardiovascular drugs, mainly anticancer drugs, can induce AF either in patients with or without pre-existing cardiac disorders, but drug-induced AF (DIAF) has not received the attention that it might deserve. In many cases DIAF is asymptomatic and paroxysmal and patients recover sinus rhythm spontaneously, but sometimes, DIAF persists, and it is necessary to perform a cardioversion. Furthermore, DIAF is not mentioned in clinical guidelines on the treatment of AF. The risk of DIAF increases in elderly and in patients treated with polypharmacy and with risk factors and comorbidities that commonly coexist with AF. This is the case of cancer patients. Under these circumstances ascribing causality of DIAF to a given drug often represents a clinical challenge. We review the incidence, the pathophysiological mechanisms, risk factors, clinical relevance, and treatment of DIAF. Because of the limited information presently available, further research is needed to obtain a deeper insight into DIAF. Meanwhile, it is important that clinicians are aware of the problem that DIAF represents, recognize which drugs may cause DIAF, and consider the possibility that a drug may be responsible for a new-onset AF episode., Competing Interests: Declaration of Competing Interest The authors declare that there are no conflicts of interest., (Copyright © 2024 The Authors.

Objective: To evaluate the effectiveness and safety of perampanel (PER) monotherapy (MT) or add-on therapy (AT) in Chinese children with epilepsy, as well as to evaluate the data from routine therapeutic drug monitoring (TDM) of PER for these pediatric patients., Methods: This retrospective and observational study was carried out on children with epilepsy (n = 340) from 2020 to 2022 at the Children's Hospital of Nanjing Medical University. Outcome measures were the responder rate (50% or greater seizure reduction), long-term efficacy, and tolerability (number and types of adverse events) in MT and AT groups. Concentrations of plasma PER obtained from these patients, if available, were analyzed too., Results: A total of 279 patients achieved at least 3 months of therapy, and 58.1% responded to PER therapy. 53 of the responders were seizure-free (32.7%). The retention rate dropped from 88.0% at 3 months to 40.6% at 12 months after treatment. Patients with MT achieved better seizure control than those with AT (P < 0.001). Intriguingly, PER exerted a very weak effect on patients who took more than 2 ASMs or were diagnosed with drug-resistant epilepsy. There were no significant differences in tolerability between the two groups. In addition, 179 patients were routinely monitored for PER, and the trough concentrations (C 0 ) for these patients ranged from 30.0 to 992.0 ng/mL. However, no significant difference in C 0 was observed between responders and nonresponders (333 ng/mL vs 325.5 ng/mL, P = 0.264)., Significance: This study provides effectiveness and safety data on Chinese children with epilepsy treated with PER either as MT or as AT. The efficacy of patients receiving MT was much better than cases administered with more than 2 ASMs or diagnosed with drug-resistant epilepsy. In addition, no association was found between the plasma PER concentration and efficacy or safety., Plain Language Summary: The study reports the effects of perampanel on seizures and adverse effects in Chinese patients with epilepsy younger than 18 years. Seizures decreased in 58.1% of patients (responders); in a third of these responders, seizures stopped. After treatment was started, 88% of patients were still on perampanel at 3 months and 40.6% at 12 months. People who were treated with perampanel only were more likely to respond than those who received perampanel and other antiseizure treatments, although perampanel was tolerated equally well in these groups. Plasma perampanel concentration did not predict seizure response or adverse effects., (© 2023 The Authors.

We sought to characterize overdose and non-overdose mortality among PLWH amidst the illicit drug toxicity crisis in British Columbia, Canada. A population-based analysis of PLWH (age ≥19) in British Columbia accessing healthcare from April 1996 to March 2017 was conducted using data from the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) cohort linkage. Underlying causes of deaths were stratified into overdose and non-overdose causes. We compared (bivariate analysis) health-related characteristics and prescription history between PLWH died of overdose and non-overdose causes between April 2009 and March 2017. Among 9,180 PLWH, we observed 962 deaths (142 [14.7%] overdoses; 820 [85.2%] other causes). Compared to those who died from other causes, those who died of overdose were significantly younger (median age [Q, Q3]: 46 years [42, 52] vs. 54 years [48, 63]); had an indication of chronic pain (35.9% vs. 27.1%) and hepatitis C virus (64.8% vs. 50.4%), but fewer experienced hospitalization in the year before death. PLWH who died were most likely to be prescribed with opioids (>50%) and least likely with opioid agonist therapy (<10%) in a year before death. These findings highlight the syndemic of substance use, HCV, and chronic pain, and how the crisis is unqiuely impacting females and younger people.

Background: In British Columbia, antiretrovirals (ARVs) for HIV treatment (HIV-Tx) and pre-exposure prophylaxis (PrEP) are free-of-charge through publicly-funded Drug Treatment Programs (DTPs). When available, less costly generics are substituted for brand-name ARVs. We describe the incidence and type of product substitution issue (PSI) adverse drug reactions (ADRs) attributed to generic ARVs., Methods: Cohorts included DTP clients ≥19 years who received generic ARVs for HIV-Tx (abacavir-lamivudine, emtricitabine-tenofovir DF, efavirenz-emtricitabine-tenofovir DF, atazanavir or darunavir between 01 Jun 2017 and 30 Jun 2022) or PrEP (emtricitabine-tenofovir DF, 01 Apr 2018 to 30 Jun 2022). Demographic, ARV and ADR data were extracted from DTP databases and summarized by descriptive statistics. PSI incidence was calculated for each product during the year following brand-to-generic and generic-to-generic transitions (first-year-post-rollout), and compared between generic versions using generalized estimating equations. For context, incidence of any ARV product-related ADR was calculated in the same 1-year periods., Results: During first-year-post-rollout periods, 5339 HIV-Tx (83% male, median age 52 years) and 8095 PrEP (99% male, median 33 years) clients received generic ARVs, and reported 78 and 23 generic PSIs, respectively. PSI incidence was <1% for most generic ARVs, with mild-moderate symptoms including gastrointestinal upset, headache, dizziness, fatigue/malaise and skin rash. In HIV-Tx clients, the efavirenz-containing product had higher PSI incidence than other ARVs (2.2%, p = .004), due to more neuropsychiatric adverse reactions. Any ADR incidence was stable across measurement periods, and generic PSIs represented less than one third of all product-related ADRs., Conclusions: Generic substitution of antiretrovirals for HIV-Tx and PrEP was well tolerated, with ≤2% incidence of mild-moderate PSI ADRs., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: JSGM’s Treatment as Prevention (TasP®) research, paid to his institution, has received support from the BC Ministry of Health, Health Canada, Canadian Institutes of Health Research, Public Health Agency of Canada, Genome Canada, Genome BC, Vancouver Coastal Health and VGH Foundation.

Introduction: Allopurinol, the first-line treatment for chronic gout, is a common causative drug for severe cutaneous adverse reactions (SCAR). HLA-B*58:01 allele was strongly associated with allopurinol-induced SCAR in Asian countries such as Taiwan, Japan, Thailand and Malaysia. HLA-B*58:01 screening before allopurinol initiation is conditionally recommended in the Southeast-Asian population, but the uptake of this screening is slow in primary care settings, including Malaysia. This study aimed to explore the views and experiences of primary care doctors and patients with gout on implementing HLA-B*58:01 testing in Malaysia as part of a more extensive study exploring the feasibility of implementing it routinely., Methods: This qualitative study used in-depth interviews and focus group discussions to obtain information from patients with gout under follow-up in primary care and doctors who cared for them. Patients and doctors shared their gout management experiences and views on implementing HLA-B*58:01 screening in primary care. Data were coded and analysed using thematic analysis., Results: 18 patients and 18 doctors from three different healthcare settings (university hospital, public health clinics, private general practitioner clinics) participated. The acceptability to HLA-B*58:01 screening was good among the doctors and patients. We discovered inadequate disclosure of severe side effects of allopurinol by doctors due to concerns about medication refusal by patients, which could potentially be improved by introducing HLA-B*58:01 testing. Barriers to implementation included out-of-pocket costs for patients, the cost-effectiveness of this implementation, lack of established alternative treatment pathway besides allopurinol, counselling burden and concern about genetic data security. Our participants preferred targeted screening for high-risk populations instead of universal screening., Conclusion: Implementing HLA-B*58:01 testing in primary care is potentially feasible if a cost-effective, targeted screening policy on high-risk groups can be developed. A clear treatment pathway for patients who test positive should be made available., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ng et al.

Background: Stroke is a neurological disease and a leading cause of mortality worldwide. Strokes mainly consist of two types: hemorrhage and ischemia. Stroke patients are being administered multiple drug therapy and are at risk of drug-related problems., Aim: To estimate drug-related problems (DRPs) and clinical end outcomes in hospitalized stroke patients., Methods: Current study was a multicenter, cross-sectional prospective observational study including 250 stroke patients admitted to tertiary care hospitals in Karachi, Pakistan. The study included all clinical subtypes of stroke patients i.e. Stroke, Ischemic stroke, Hemorrhagic stroke, CVA, and TIA. Associations among patient-clinical end outcomes and drug therapy-related variables like DRPs, mortality, and morbidity rates were estimated using Pearson's chi-squared test. Statistical analysis was done by using SPSS software, version 25., Results: A total of 250 patients participated in this study suffering from different clinical subtypes of stroke i.e. Ischemic stroke, hemorrhagic stroke, TIA, and CVA, including 46% male and 54% female patients. The majority of patients' stay at the hospital was between 1-10 days. The overall mortality rate in stroke patients was 51%. HAIs were observed in 70% of patients, HAIs faced by patients were SAP, CAP, UTI, sepsis, and VAP. Drugs were assessed according to NEML i.e. access group antibiotics, watch group antibiotics, reserve group antibiotics, statins, antiepileptics, and proton pump inhibitors. Majorly ceftriaxone was administered to 79% of patients, piperacillin-tazobactam to 52%, and cefixime to 48%, whereas meropenem was administered to 42% of patients along with vancomycin to 39% of total patients. A high mortality rate was observed in the case of Klebsiella pneumoniae and Staphylococcus aureus i.e. 78% and in the case of streptococcus pneumoniae 61% mortality rate was observed. Due to the presence of DRPs and various other clinical factors like comorbidities, DDIs, HAIs, administration of potentially nephrotoxic drugs, and administration of antibiotics without having CST, hospitalized stroke patients faced many problems., Conclusion: This study helped determine DRPs along with various clinical factors affecting the clinical end outcomes of patients suffering from any clinical subtype of stroke. Due to the enhancement in the evidence of the incidence of DRPs in tertiary care hospitals, pharmacist-led drug therapy review by interfering with doctors and other medical professionals at the patient bed site is needed and should be done to avoid any negative end outcomes and serious issues related to DRPs., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ali et al.

Objectives: There is a need for early identification and intervention of Adverse Drug Reaction (ADR) to alleviate the unacceptably growing burden, morbidity, and mortality associated with People With Epilepsy (PWE). This study is aimed at identifying associated factors and predictors of ADR among PWE., Methods: It is an interviewer-administered questionnaire-based study consisting of 940 consenting participants aged 16 years and above attending epilepsy clinics for 5 years with diagnosis confirmed by International League against Epilepsy (ILAE) criteria and supported by Electroencephalography (EEG). Twenty-one-item Liverpool Adverse Effect Profile (LAEP) and 8-item Morinsky Medication Adherence Scale (MMAS) were used to assess ADR and adherence respectively., Results: The highest reported ADR in PWE were nervousness (34.3%), aggression (33.6%), and weight gain (32.3%). Specifically, 20.1% of the participants complained of memory problems. On the other hand, ADR associated with skin, mouth/gum and hair loss was 9.3%, 8.9%, and 7.2% respectively, and these were the lowest reported ADRs. Using the MMAS, 545(90.2%), 28(4.6%), and 31(5.1%) of PWE in this study were classified as having high, medium, and low adherence, respectively. Duration of Anti-Seizure Medication (ASM) use and duration of epilepsy were the major determinants of ADR in PWE on the regression model., Conclusion: Duration of ASM use and duration of epilepsy are the major determinants of ADR in PWE. Effective strategies to identify and reduce ADR should be incorporated into the management of PWE by Health Care Providers (HCPs) to improve their quality of life., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Background: Anemia is extremely common among patients admitted to pediatric intensive care. Alternative treatments to transfusions such as intravenous iron must be considered. There are no published data for a prospective intravenous (IV) iron study focused in the critically ill children. The objective is to examine the safety and efficacy of intravenous iron sucrose infusion to manage anemia in pediatric critical care. A secondary objective is to examine the effect of different dose regimens of iron sucrose (3, 5, and 7 mg/kg dose)., Procedure: Prospective investigation of intravenous iron sucrose utilization at a tertiary pediatric intensive care unit between October 2017 and November 2022., Results: In all 115 patients received a total of 616 infusions of IV iron. Transferrin saturation index (TSI) was the most common altered iron deficiency biomarker (91.8%). After IV iron treatment, hemoglobin showed a significant increase within a 30-day follow-up (9.2 vs. 11.6 g/dL, p < .001). There was also a significant improvement in TSI and serum iron (p < .001). Iron deficit replacement was higher in the 7 mg/kg dose group (94%) compared to 85.9% in the 5 mg/kg regimen and 77.5% in the lower dose group (p = .008), requiring less doses and a shorter time. Very few mild adverse reactions were reported (1.3% of infusions), with no differences between groups. The most frequent adverse effect was gastrointestinal in three cases. There were no anaphylaxis-like or other serious/life-threatening adverse effects., Conclusions: This is the first study to evaluate intravenous iron therapy in pediatric critical care, providing preliminary evidence of safety and efficacy of IV iron sucrose. The 7 mg/kg dose regimen showed higher iron deficit replacement in a shorter time, which could be beneficial in critically ill children., (© 2023 The Authors.

Antibiotic prophylaxis is the use of antibiotics perioperatively to prevent infections at the surgical site or distant locations. The decision to provide prophylaxis must balance risks of antibiotic resistance, adverse drug reactions, and increased health care costs with the benefit of decreasing infection. This determination has been studied extensively in patients with specific cardiac conditions and prosthetic joints. Prophylactic antibiotics in healthy patients have been shown to reduce the frequency of alveolar osteitis and decrease the failure rates of dental implants., (Copyright © 2023 Elsevier Inc.

Purpose: The Liverpool Adverse Event Profile (L AEP) is commonly used in clinical practice and pharmacological trials for the monitoring of side effects of anti-seizure medication (ASM). However potentially unrelated, additional symptoms and normative data should be considered to put patients´ complaints into perspective., Methods: An extended 32-item AEP (E AEP) was given to 537 healthy subjects and 1,605 patients with epilepsy as part of the Bonn ASM side effect registry. The tool was factor-analyzed, corrected for age, gender, and repeated application, and related to drug load and individual substances (with N> 100) on item and scale level (total E AEP and its subscales cognition, dizziness, energy, mood, bodily symptoms, aggression, and sexuality)., Results: Compared to non-normalized results, at item level, between one and two-thirds of responses suggesting impairment were found to be unlikely to be related to ASM treatment after normalization. Binary regression analyses revealed differential effects of medication choice, but also of antidepressants and neuroleptics on complaint domains. The explained variance was better for physical than psychological domains. The results reflect both known drug side effects and indications. Patients´ explicit attribution of problems to their medications barely improved the correlation of the E AEP and treatment parameters., Conclusion: Application of a norm-referenced AEP is highly recommended to avoid overestimation of treatment related problems in patients with epilepsy. It allows evaluation on item and scale level for individuals as well as groups in drug trials. Plausible relations to individual drugs and to drug load can be demonstrated. The explanatory power was better for physical than psychological domains. Drug-related complaint patterns reflect known drug side effects (e.g. perampanel and brivaracetam with aggression) as well as drug indications (e.g. lamotrigine for depression). This is likely to be particularly relevant when side effects may have affected treatment decisions. Longitudinal evaluation with repeated application of the E AEP with changes of drug treatment is in progress., Competing Interests: Declaration of Competing Interest CH has nothing to declare in regard to the present work.

Background: Isotretinoin is frequently used for treatment of severe nodulocystic and papulopustular acne, however use is limited by mucocutaneous, ocular, and systemic side effects. Objective: (1) provide a systematic meta-analysis of ocular side effects during isotretinoin use and their corresponding incidences; (2) provide a narrative summary of ocular side effects during isotretinoin use reported in case reports. Methods: A systematic database search using predefined search terms was performed in PubMed, EMBASE, and Scopus from inception to 5 March, 2021. Predetermined inclusion and exclusion criteria were used to select included studies. In total, 53 original studies qualified for meta-analysis, and 41 case reports/series qualified for narrative results. Results: The studies included in the meta-analysis reported incidences of various ocular side effects including dry eye, eye sensitivity, vision changes, and ocular inflammatory conditions. Incidences across studies did vary, leading to considerable heterogeneity. The narrative results summarize more uncommon, but equally important, ocular side effects. Conclusions: Dry eye is the most commonly reported ocular side effect. Other less common, but more serious, ocular side effects including vision changes can occur. We recommend that isotretinoin prescribers monitor for dry eye. Limitations include the heterogeneity of reported incidences of ocular side effects between studies.

Objective: To provide an integrated approach for deprescribing practice in oncology setting., Data Sources: The data on deprescribing in oncology settings has been retrieved from the PubMed, Scopus and Google Scholar. We used "deprescribing," "potentially inappropriate medication" and "cancer" as a keyword for the conducting general search. The articles relevant to guidelines or tools used to deprescribe in cancer care were included., Data Summary: The nature of cancer, its treatment strategies, adverse effects of therapy and multimorbidity impact negatively on quality of life (QoL). Further, they invite polypharmacy which puts the patient at higher risk of drug-related problems like drug interactions, adverse drug reactions and addition of potentially improper medications, etc. In older adults with cancer, the incidence of potentially inappropriate medications (PIMs) was between 41% and 52%. Over the decades, multiple strategies have been developed to assess the appropriateness of therapy. One such approach is deprescribing. OncPal and oncoSTRIP (Systematic Tool to Reduce Inappropriate Prescribing) are the cancer specific guidelines whereas BEERs criteria, Screening Tool to Alert to Right Treatment/Screening Tool of Older Person's Prescriptions criteria (START/STOPP criteria), medication appropriateness index (MAI) are the cancer nonspecific tools to identify PIM among cancer patients. Here, we provided an integrative approach and algorithm for deprescribing in oncology setting which includes patient and caregiver goals, life expectancy (LE), review of medications, determining medication appropriateness, assessment of time to benefit (TTB), symptomatic and asymptomatic care, identifying medications to cease, implementation of the plan, monitoring and reviewing., Conclusion: Deprescribing in oncology setting is a novel and effective patient-centric approach to counteract the use of PIM, which helps to mitigate polypharmacy, drug-drug interactions, and adverse effects., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To identify the impact of lamotrigine (LTG) on cardiac rhythm and conduction abnormalities for Veterans, an especially vulnerable population., Background: In October 2020 the US Food and Drug Administration (FDA) added a new warning to the label of lamotrigine (Lamictal™) regarding its potential to cause cardiac rhythm and conduction abnormalities [1]. This warning came following in vitro data which suggested Class IB antiarrhythmic effects occurring at clinically achievable concentrations of lamotrigine [2]. However, it is unclear whether the in vitro findings will result in adverse clinical outcomes. Our objective was to assess for evidence for adverse clinical outcomes in a vulnerable population and examine for subtler signs of an association between lamotrigine and cardiac rhythm disturbances., Methods: A retrospective chart review was conducted using records between 10-01-2017 and 07-06-2021, identifying patients at the William S. Middleton Memorial Veterans Hospital who were prescribed lamotrigine. Data collected included: dates of lamotrigine initiation or discontinuation, lamotrigine dosing over the time of the prescription and maximum lamotrigine dose, any cardiac-related ICD-10-CM codes or a history of a cardiology appointment, EKGs with any abnormalities or changes, any concomitantly prescribed medications with known potential to cause cardiac abnormalities, any cardiac deaths. This retrospective chart review was approved by the University of Wisconsin-Madison Institutional Review Board., Results: Two hundred and thirty-three (189 male) patients with a lamotrigine prescription and 41.2 % (n = 96) of these patients had an EKG performed while prescribed lamotrigine. The average age of patients was 64.3 ± 13.0 (range 29 to 90) years and mean maximum lamotrigine daily dose was 250.8 ± 148.2 mg (range 25 to 800 mg). Nearly half (47.9 %, 46/96) of the patients were prescribed a concomitant sodium channel blocking medication in addition to lamotrigine. Eighty-four of the patients (87.5 %, 84/96) had a cardiac diagnosis, while 12 (12.5 %, 12/96) did not. A total of 12 deaths occurred within the review period, with two cardiac deaths from congestive heart failure. Four cases did not have information on cause of death. No LTG-associated cardiac adverse effects were noted as part of clinical care, though rash was noted in 5 cases. A total of 7 (7.3 %, 7/96) patients were found to have EKG abnormalities potentially related to lamotrigine, including 7.1 % (6/84) of those with a cardiac diagnosis and 8.3 % (1/12) of those without a cardiac diagnosis., Conclusions: While recent FDA warnings have suggested caution regarding cardiac complications associated with lamotrigine based on in vitro studies, the clinical implications are uncertain. Despite selecting a particularly vulnerable population, this retrospective chart review did not identify any deaths due to cardiac rhythm or conduction causes, nor demonstrate unambiguous cardiac complications related to lamotrigine. Even using permissive criteria (including any prolonged PR or QTc) to examine for subtle effects, only a low incidence (<10 %) of potential complications was found. Broader implications of this study are limited by the number of patients included and the retrospective nature of the study. Therefore, further studies are warranted to evaluate a link between cardiac complications and the use of lamotrigine, including the role of concomitant medications such as other sodium channel blocking agents and psychotropic medications., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Biehl, Taube, Kotloski, Jones, Kopacek report no COI.

Background: Chronic pruritus is frequently seen in daily dermatological practice and is associated with marked impact on quality of life. Research on the use of gabapentin and oral antidepressants in daily dermatological practice is scarce., Objective: To evaluate the efficacy and safety of gabapentin and oral antidepressants in patients with chronic pruritus in daily clinical practice., Methods: A prospective observational single-center cohort study was conducted including adult patients with chronic pruritus and an indication for systemic treatment between June 2016 and May 2019., Results: Systemic treatment with gabapentin and/or antidepressants was initiated in 31 patients with severe chronic pruritus (median average pruritus NRS score 7.0), in which most cases no underlying origin was identified (83.9%). In patients treated with gabapentin 900-1800 mg/day ( N  = 25), median average pruritus NRS decreased to 5.5 (IQR 3.0) after 4 weeks and remained stable up to 24 weeks of treatment. Efficacy of antidepressants was variable, with the highest response after initiation of amitriptyline, nortriptyline, and mirtazapine. Side effects were frequently observed in both gabapentin and antidepressant treatments; however, were mostly mild and temporary., Limitations: This was a single-site observational study, with limited sample size., Conclusion: Treatment with gabapentin and antidepressants should be considered in patients with chronic pruritus unresponsive to conventional treatment.

Background: Currently, two-drug antiretroviral regimens are emerging fields in life-long treatment in people living with HIV., Objectives: This randomized non-inferiority open-label controlled trial was designed to compare the 48-week efficacy and safety of tenofovir alafenamide plus dolutegravir versus the standard triple therapy in virologically suppressed people living with HIV. To the best of our knowledge this combination has not been studied before., Methods: This open-label randomized controlled trial was conducted in treatment-experienced people with HIV who had HIV-RNA < 47 copies/mL for at least two years. Patients received either tenofovir alafenamide plus dolutegravir combination (26 patients) or a standard three-drug regimen (29 patients). The primary outcome was the proportion of patients maintaining HIV-RNA < 47 copies/mL during 48 weeks, and the secondary outcomes were CD4 cell count changes, the adherence rate, and adverse drug reactions, all over 48 weeks of study., Results: HIV viral load remained undetectable (HIV-RNA < 47 copies/mL) during the 48 weeks of the study in both arms. The absolute CD4 cell count change was not significant between the two groups. The overall proportion of adverse effects in each group was comparable. The rate of adherence to treatment was acceptable in both groups, and no significant difference was observed., Conclusions: Treatment simplification with tenofovir alafenamide plus dolutegravir regimen as maintenance therapy was non-inferior in terms of efficacy and safety compared to the standard triple therapy.

Aims: To present a review of the mechanisms of action, available clinical data, and safety profiles of novel migraine therapeutics to inform practice. Methods: PubMed, Medline, and Google Scholar were searched for randomized controlled trials (24 publications), review articles (15 publications), and other pertinent literature (16 publications) discussing the novel migraine therapeutics available between the years 2010 and 2021. All publications were reviewed to assess the mechanism of action, relevant clinical data, and side effect profile for each novel treatment. Therapeutic gain was also recorded in studies that included a placebo arm. Results: A total of 55 studies were included in the final analysis. In the preventive treatment of migraine, novel medications target calcitonin gene-related peptide (CGRP) and fall into either the monoclonal anti-CGRP or gepant class. For the acute treatment of migraine, novel medications fall into either the ditan or gepant class. Several medical devices have been developed for the acute and preventive treatment of migraine. Conclusion: Novel therapeutics are available for both the prevention and acute treatment of migraine headaches. These new medications and neuromodulatory devices appear overall to be safe and effective in the management of migraine headaches.

Traditional ophthalmic drugs, such as eye drops, gels and ointments, are accompanied by many problems, including low bioavailability and potential drug side effects. Innovative ophthalmic drug delivery systems have been proposed to overcome the limitations associated with traditional formulations. Recently, contact lens-based drug delivery systems have gained popularity owing to their advantages of sustained drug delivery, prolonged drug retention, improved bioavailability, and few drug side effects. Various methods have been successfully applied to drug-loaded contact lenses and prolonged the drug release time, such as chemical crosslinking, material embedding, molecular imprinting, colloidal nanoparticles, vitamin E modification, drug polymer film/coating, ion ligand polymerization systems, and supercritical fluid technology. Contact lens-based drug delivery systems play an important role in the treatment of multifarious ophthalmic diseases. This review discusses the latest developments in drug-loaded contact lenses for the treatment of ophthalmic diseases, including preparation methods, application in ophthalmic diseases and future prospects.

Background: Paclitaxel has a risk of infusion-related reactions (IRRs) and despite no prospective evidence, is often given with premedication including a corticosteroid, H1 antagonist, and H2 antagonist (H2RA). Backorders impacted the supply of intravenous H2RAs at our center, and it was removed as routine premedication. The authors compared the incidence of IRR in patients treated without H2RA to patients receiving standard H2RA premedication., Methods: The authors reviewed outpatients starting paclitaxel at the Ottawa Hospital from December 2019 to October 2021. Two cohorts were created: patients treated without H2RA premedication (intervention), and those receiving standard H2RA (control). Demographics, treatment, and IRR information were collected retrospectively. Primary end point was rate of grade ≥2 IRRs during first two doses of paclitaxel., Results: A total of 182 patients were treated without H2RA premedication, compared to 184 control patients treated during non-backorder periods. Baseline characteristics included: median age, 63 years; 86% female; and primary tumor 52% breast/24% gynecologic/10% gastric/esophageal/8% lung/6% other. There were no significant differences between cohorts in baseline characteristics. There was no difference in the rate of grade ≥2 IRR between cohorts; 12.1% (22 of 182; 95% confidence interval [CI], 7.7%-17.7%) for patients treated without H2RA, and 15.1% (28 of 185; 95% CI, 10.3%-21.1%) for control patients. The rate of grade ≥3 IRRs were also similar, 4.4% in intervention cohort versus 3.8% in control cohort., Conclusions: The removal of H2RAs from premedication for paclitaxel did not result in an increased incidence of IRRs. The use of H2RAs in preventing IRRs to paclitaxel should be re-evaluated., (© 2023 American Cancer Society.)

Anti-angiogenesis therapy plays a vital role in the treatment of tumors, with anlotinib as its representative targeted drug. Anlotinib is a novel oral tyrosine kinase inhibitor (TKI) with inhibitory effects on tumor growth tumor angiogenesis. In Phase III clinical trials, anlotinib demonstrated better overall survival and progression-free survival than placebo in patients with advanced non-small cell lung cancer (NSCLC), and was approved for the first time as a third-line treatment for refractory advanced NSCLC. Going far beyond that, anlotinib has shown encouraging results in a variety of malignancies, including medullary thyroid carcinoma, renal cell carcinoma, gastric cancer and esophageal squamous cell carcinoma. Nevertheless, anlotinib has been subject to some controversy in terms of adverse events due to its widespread use. In this review, the mechanism of action, pharmacokinetic characteristics, adverse reactions in clinical use and management of anlotinib were summarized., Competing Interests: The authors report no conflicts of interest related to this study., (© 2023 Li and Wang.)

Patients with incurable cancers have an increasing number of comorbidities, which can lead to polypharmacy and its associated adverse events (drug-to-drug interaction, prescription of a potentially inappropriate medication, adverse drug event). Deprescribing is a patient-centered process aimed at optimizing patient outcomes by discontinuing medication(s) deemed no longer necessary or potentially inappropriate. Improved patient quality of life, risk reduction of side effects or worse clinical outcomes, and a decrease in healthcare costs are well-documented benefits of deprescribing. Deprescribing and advance care planning both require consideration of patients' values, preferences, and care goals. Here, we provide an overview of comorbidities and associated polypharmacy risks in cancer patients, as well as useful tools and resources for deprescribing in daily practice, and we shed light on how deprescribing can facilitate advance care planning discussions with patients who have advanced cancer or a limited life expectancy.

Background: Nalmefene is a potent opioid antagonist that has recently been reintroduced in the United States to treat known or suspected opioid overdose., Nalmefene Clinical Trial Data: The injection formulation, which had been withdrawn in 2008, was reintroduced in 2022, and in 2023 the United States Food and Drug Administration approved a new intranasal formulation of nalmefene. Because nalmefene had been previously approved for use in 1995 via injection, the new intranasal formulation did not require new clinical data as it was approved under an Abbreviated New Drug Application. Inherent to this abbreviated approval process, intranasal nalmefene was not studied in patients currently suffering opioid overdose., Naloxone and Nalmefene: Nalmefene also has unique characteristics compared with naloxone, the current standard opioid antidote. Nalmefene has a higher affinity for opioid receptors and a longer duration of action than naloxone. Comparative effectiveness data regarding naloxone and nalmefene are sparse, and it is unclear if the inherent properties of nalmefene are beneficial in opioid overdose. We have decades of experience using naloxone safely and effectively as the primary opioid antidote, even in cases of fentanyl and fentanyl analog overdoses. There is, however, evidence to suggest nalmefene may result in more prolonged and severe opioid withdrawal than naloxone, which could be harmful to patients., Position: As nalmefene is untested in the current clinical environment of synthetic opioid overdoses and has the potential to cause harm via prolonged withdrawal, it is the opinion of the American College of Medical Toxicology and the American Academy of Clinical Toxicology that nalmefene should not replace naloxone as the primary opioid antidote at this time., Recommendations: We recommend additional clinical studies of nalmefene, administered via all approved routes, be conducted in a comparative fashion with naloxone, and that safety and effectiveness outcomes be evaluated before nalmefene is recommended as a primary opioid antidote.

Introduction: Pharmacogenetics is a potential approach that can be applied to decline the burden of rivaroxaban's ADRs. The current systematic review and meta-analysis aim to identify genetic variants correlated with rivaroxaban exposure and evaluate their importance., Methods: We systematically searched PubMed, Web of Science, and Scopus databases for all observational and interventional studies. The fixed effect method was used to pool the data when the Q-test's p value was higher than 0.1. We used random models when the p value was less than 0.1., Results: Data from ten studies (4721 participants) were analyzed in the current review. Qualitative synthesis from included studies found that two variants of ABCB1 (rs1045642 and rs2032582) and one variant of APOB (rs13306198) are potential contributors to rivaroxaban concentrations. Both wild homozygotes (AA) and heterozygotes (AC) of rs1045642 have significantly lower rivaroxaban concentrations compared to mutated homozygotes (CC) (SMD = 0.516, 95% CI: 0.115 to 0.917; SMD = 0.772, 95% CI: 0.088 to 1.455, respectively). Nevertheless, pooling unadjusted odds ratios did not yield a statistically significant correlation between rivaroxaban ADRs and genetic mutations., Conclusion: This study revealed that being an AC or CC for rs1045642 is attributed to a considerably higher rivaroxaban level in participants using rivaroxaban. That is to say, rs1045642 is a remarkable predictor of rivaroxaban metabolism. We concluded that identifying rs1045642 before drug administration might decrease ADRs although further studies adjusted for potential confounders are strongly suggested., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Parham Mardi et al.)

Background: The duration of the induction phase of allergen-specific immunotherapy conventionally is a period of several weeks, during which the volume of an allergen solution, administered by injection, is gradually increased until the maintenance dose is reached. In rush immunotherapy (RIT), the induction period is abbreviated to achieve a faster improvement in clinical signs of atopic dermatitis (AD) compared to conventional immunotherapy., Objective: The aim of this retrospective study was to evaluate the safety of RIT in 230 dogs with AD and report any adverse effects (AE)., Animals: Two hundred thirty client-owned dogs., Materials and Methods: Medical records of dogs receiving RIT between 2012 and 2021 were analysed and observed AE were investigated. All dogs underwent RIT following a protocol of subcutaneous allergen extract injections, given hourly with an incrementally increasing volume from 0.1 to 1.0 mL., Results: Adverse effects were documented in 6 of 230 (2.6%) dogs. Five of these dogs (2.2%) showed mild gastrointestinal signs (1 of 5 vomiting, 4 of 5 diarrhoea) and one patient an increase in body temperature by 1.5°C. These occurred at different stages of the RIT protocol. All AE were graded as mild and self-limiting., Conclusions and Clinical Relevance: Based on these data, supervised RIT in dogs appears to be a safe procedure to achieve the maintenance dose of allergen immunotherapy earlier with infrequent and mild AE., (© 2023 The Authors.

Background: Clozapine is an anti-psychotic agent, reserved for treatment-resistant schizophrenia, with demonstrated efficacy in an otherwise therapeutically challenging patient population. We aimed to review the full spectrum casemix of clozapine presentations to our tertiary toxicology service., Methods: In this retrospective study, we reviewed consecutive clozapine related toxicity presentations to a tertiary medical toxicology inpatient and consultation service-including deliberate self-poisoning (DSP), adverse drug reaction (ADR), recreational use, and therapeutic misadventure over a 10-year period from 2011 to 2021. Data were extracted for demographics, ingested dose, exposure characteristics, and patient outcome., Results: We identified 83 patients with clozapine-related presentations over the 10-year period. Twenty-two patients were excluded. Of the remaining 61 patients, 28 patients presented with DSP, 20 patients with accidental overdose, and 13 patients with an ADR; no patients presented with recreational use. It was noted that ADRs were largely idiosyncratic reactions and not always related to dose adjustments. In the context of therapeutic misadventure and DSP, we noted that a lower mean dose achieved a higher poison severity score (PSS) in clozapine-naive patients when compared to those patients on regular clozapine., Conclusions: The presentation of clozapine-related toxicity differs depending on the modality of ingestion, whether DSP, accidental, or as a result of ADR. Patients naive to clozapine therapy tend to experience higher PSS with lower doses ingested either in a deliberate self-poisoning or accidental ingestion context. This is likely due to tolerance to the sedative properties of clozapine. No patients manifested clinical toxicity greater than 8 hours after ingestion, with an observation period of 6 hours accurately identifying toxicity in most patients., (© 2023. Crown.)

Purpose: To report a rare case of cystoid macular edema (CME) as a presentation of acute hydroxychloroquine-related retinal toxicity., Observations: A 37-year-old female patient visited our ophthalmology department in October 2019 complaining of bilateral blurred vision and metamorphopsia for 3 days. Best-corrected visual acuity (BCVA) was 6/6 in the right eye and 6/7.5 in the left eye under the Snellen E chart. Before presentation, she had taken hydroxychloroquine as a "reproduction-facilitating medication" prior to the in vitro fertilization (IVF) procedures with the daily dose of 200 mg for 1 week in March 2019 and 400 mg for 1 month in September 2019. She also took a combination of several herbal medicine including "Angelica sinensis" for 6 months in this period. On examination, typical signs of hydroxychloroquine maculopathy such as bilateral paracentral retinal pigment epithelium (RPE) change in blue autofluorescence and loss of the paracentral ellipsoid zone in optical coherence tomography ("flying saucer sign") were noted. CME was also found in fluorescein angiography. Her symptoms improved gradually after cessation of hydroxychloroquine and herb medicine without any further treatment. Resolution of bilateral CME was revealed at 16 weeks with final bilateral BCVA 6/6., Conclusions and Importance: Although rare, acute hydroxychloroquine maculopathy could occur in patients with concomitant usage of medications that could interfere with P450 enzymes system. Careful acquisition of drug history and serial ophthalmological examinations are advised in using hydroxychloroquine for disease management even for a short period of time.

Current myasthenia gravis guidelines recommend the use of azathioprine as first-line steroid sparing agent. However, due to its high cost, compliance to azathioprine is low in developing countries. To determine the efficacy and safety of the cheaper methotrexate as an alternative immunosuppressant, Medline/Pubmed, Embase and Cochrane databases and references were searched for clinical trials and observational studies using the search terms: "Myasthenia OR Myasthenia Gravis OR anti AchR antibody positive Myasthenia Gravis OR anti-MuSK antibody Myasthenia Gravis OR MG" AND "Methotrexate". Of 78 possible articles, only 4 were selected using the following eligibility criteria: population: generalized MG patients; intervention: methotrexate; and outcome: effectiveness, steroid sparing efficacy and adverse effects. Two clinical trials and one observational study noted improvement in different MG outcomes in patients given methotrexate. While one randomized controlled clinical trial concluded that methotrexate has no steroid sparing benefit, a single blinded clinical trial established that methotrexate was a better steroid sparing agent than azathioprine starting at 10th month of use. Adverse effects were rare with non-specific pain and elevated transaminases as the most common complaints. Based on available evidence, MTX may be a safe and effective alternative to AZA as steroid sparing agent in developing countries., (© 2023.

Background: Immunosuppression is an integral part of treating chronic spontaneous urticaria (CSU), but there is no literature to evaluate the efficacy of multiple immunosuppressive agents., Objective: The comparison of the efficacy, safety, and incidence of adverse effects of four immunosuppressive medicines (tripterygium glycosides, methotrexate, cyclosporine A, and azathioprine) in combination with antihistamines in treating CSU provides a clinical reference and evidence-based medicine for treating CSU., Methods: PUBMED, The Cochrane Library, EMBASE, WANFANG, CNKI, CBM, and clinical trial registration platform were searched to collect relevant randomized controlled trials (RCT) and cohort studies of four immunosuppressive medicines combined with antihistamines for treating CSU. The primary outcomes were the efficacy of weekly urticaria activity score 7 (UAS7) and adverse effects., Results: This study pooled data from seven randomized clinical trials with 410 participants. The standardized mean differences for change in UAS7 were 0.10 (95% confidence interval (CI), 0.01 to 0.68) for cyclosporine A plus antihistamine; 0.03 (95% CI, 0.00 to 0.23) for azathioprine plus antihistamine; 0.52 (95% CI, 0.32 to 0.85) for tripterygium glycosides plus antihistamine; and 1.54 (95% CI, 0.64 to 3.67) for methotrexate plus antihistamine. There were no significant differences in side effects between these medicines in the limited number of trials and clinical samples., Conclusion: Our results indicate that cyclosporine A combined with antihistamine resulted in greater improvements regarding the UAS7 in CSU patients and that tripterygium glycosides are also effective in treating CSU., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Background: Parkinson's disease (PD) is a serious neurodegenerative condition impacting many individuals worldwide. There is a need for new non-invasive treatments of PD. Cannabinoids in the form of cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) may offer utility as treatment, and our objective was hence to conduct a systematic review regarding the clinical evidence for the efficacy and safety of cannabinoids in treating PD. Methods: Screening, data extraction, and quality assessments were all conducted by multiple reviewers, with discrepancies resolved by consensus. Results: After conducting searches in 4 different databases, 673 articles were screened. Thirteen articles were deemed eligible for inclusion in this review. It was shown that cannabis, CBD, and nabilone (a synthetic form of THC) were capable of consistently improving motor symptoms more than a placebo. All treatments improved various non-motor symptoms, particularly with cannabis improving pain intensity, and CBD improving psychiatric symptoms in a dose-dependent manner. Adverse effects were usually minor, and, in the case of CBD, rare (except at very high doses). Conclusion: Cannabinoids have been shown to safely offer important potential in treating motor symptoms in PD and some non-motor symptoms. More large-scale randomized control trials for specific forms of cannabinoid treatments are required to determine their overall efficacy.

Introduction: Azacitidine (AZA), a demethylating agent, is one of the mainstay treatments for patients with myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML) who are ineligible for curative allogeneic stem-cell transplantation and is recommended as first-line treatment in multiple countries. While arthralgia and myalgia have been commonly reported as side effects, the incidence of drug-induced reactive arthritis has only been reported twice so far., Case Report: We present a retrospective overview of a clinical case of a 71-year-old patient that developed new cytopenias on a background of Chronic Lymphocytic Leukaemia and was diagnosed with therapy-associated AML. His treatment included an indefinite course of AZA to induce remission and optimise long-term survival which resulted in a satisfactory haematological response. However, after his ninth AZA cycle, he presented to the emergency department with knee swelling and erythema and conjunctivitis., Management and Outcomes: Arthrocentesis of the knee revealed reactive arthritis with no crystal or organism growth. His symptoms were managed effectively with conservative management including NSAIDs, analgesia and temporary immobilization for joint rest. The adverse drug reaction probability score in our study was calculated as six and adverse drug reaction was thus assigned to the "probable" category., Conclusion: We report a case that points to AZA as a probable cause of arthritis flares in MDS patients. The current limitation of this study is the lack of available data, future reviews and research will aid in providing stronger evidence of a correlation between arthritis and AZA treatment.

Introduction: Pembrolizumab is an immune checkpoint inhibitor that promotes effector T-cell functions on malignant cells by binding to programmed cell death protein 1 (PD-1). Pembrolizumab is well tolerated in most cases with an adverse event profile consisting mainly of pruritus, fatigue, and anorexia. Cardiotoxicity comprises 1% of the total adverse events., Case Report: We present a case of a 64-year-old female with non-small cell lung cancer (NSCLC) who developed pleuropericarditis following pembrolizumab therapy., Management & Outcome: The patient was successfully managed with colchicine, furosemide, and timely initiation of methylprednisolone with the improvement of her symptoms. The decision to discontinue pembrolizumab was made, and six months after this intervention, the patient has remained asymptomatic., Discussion: Clinicians should recognize these potential immune-mediated adverse effects to provide effective and timely management and optimize patient care.

Aim: Aim of our study was to evaluate cancer patients' knowledge about their chemotherapy regimens in order to assess educational needs of patients., Methods: Study was conducted on 58 colorectal carcinoma patients who were treated in an outpatient chemotherapy unit. These patients had received a 2-page information pamphlet about their chemotherapy treatments before the commencement of treatment. During the first interview with patients, pharmacist collected demographic data and evaluated patients' knowledge about their medications using a standardized questionnaire., Findings: Mean age of the patients was 59.6 ± 1.3 years; 65.5% were male. Majority (77.6%) of patients were graduates of primary school. Sixty-four percent of these had at least one comorbid disease. Median number of chemotherapy courses already received by patients was 4 (1-9). Fifty-nine percent reported that they did not receive any patient education and 43.1% reported that they did not receive any informative document. Twenty-nine percent of patients did not know what actions to take in case of nausea-vomiting; while 53.4% did not know how to react if their body temperature exceeded 38 °C and 25.9% had no idea about dietary necessities. About one-third of patients did not pay attention to oral care., Conclusion: Our study showed that patients did not understand (or remember) the basic points about their chemotherapy sufficiently, but remembered the adverse effects they experienced occasionally. Pharmacists will have the chance to increase the level of knowledge of the patients receiving chemotherapy by providing patient education and follow-up.

Introduction: Immune-checkpoint inhibitor therapy modulates the response of the immune system acting against cancer. Two pathways impacted by this kind of treatment are the CTLA4 and the PD-1/PD-L1 pathways. ICI therapy can trigger autoimmune adverse effects, known as immune-related Adverse Events (irAEs)., Areas Covered: This review focuses on irAEs which affect the endocrine system. This review elucidates the pathways used by these drugs with a focus on the hypothetical pathogenesis at their basis. In fact, the pathophysiology of irAEs concerns the possibility of an interaction between cellular autoimmunity, humoral immunity, cytokines, chemokines, and genetics. The endocrine irAEs examined are thyroid dysfunctions, immune related-hypophysitis, diabetes, peripheral adrenal insufficiency, and hypoparathyroidism., Expert Opinion: There is still much to investigate in endocrine irAES of checkpoint inhibitors. In the future, checkpoint inhibitors will be increasingly utilized therapies, and therefore it is crucial to find the proper diagnostic-therapeutic program for irAEs, especially as endocrine irAEs are nonreversible and require lifelong replacement therapies.

Introduction: Adverse drug reactions (ADRs) to antiseizure therapy can worsen the quality of life, reduce adherence, and potentially lead to treatment discontinuation and uncontrolled seizures., Objectives: The aim of the study was to develop a prognostic model for ADRs to antiseizure therapy in adult patients with epilepsy from Colombia., Methods: This case-control study included adult patients with epilepsy, who were separated into two groups: one group with ADRs to antiseizure therapy (cases), as determined by a complete evaluation conducted by an epileptologist, and another group without ADRs (controls). Variables were analyzed to identify statistical differences between the two groups and were then selected to construct a prognostic model using logistic regression. The Bonferroni method was applied for multiple comparisons., Results: Three hundred fifty-four patients with epilepsy were studied. One hundred and fifty (42%) patients had ADRs and 204 (57%) patients did not have ADs. A total of 362 ADRs were reported, with a third of them being general symptoms and most frequently occurring with older-generation antiseizure drugs (58%). Female sex, drug-resistant epilepsy, LEV, and CZP were risk factors, whereras the presence of tumoral etiology, absence of seizure triggers, and VPA were identified as protective factors. A prognostic model was constructed using previously reported risk factors for ADRs to antiseizure therapy and other variables available in this population study. In the multivariable analysis, the number of previously used antiseizure drugs (1, 2, or ≥3), TPM, CZP, LEV, PHT, and female sex were predictors of ADRs. The corrected p-values were estimated by the Bonferroni method; however, not all the variables achieved statistical significance with this adjustment., Conclusions: In adult patients with epilepsy from Colombia, we found that the number of previously used antiseizure drugs, TPM, CZP, LEV, PHT, and female sex were predictive factors for ADRs to antiseizure therapy., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have seemed to influence the work reported in this paper., (Copyright © 2023 The Authors.

Although there are many atopic dermatitis (AD) treatments, finding a long-term medication with minimal side effects can be difficult. This review characterizes lebrikizumab as AD treatment in adults. A literature search was conducted to examine lebrikizumab's role in treating moderate to severe AD. In a phase III trial, 74% of adults with AD treated with lebrikizumab 250 mg every 4 weeks achieved an Investigator Global Assessment of 0/1, 79% achieved Eczema Area and Severity Index 75 and 79% experienced improvements in pruritus numeric rating scale scores relative to placebo. Common adverse effects in the ADvocate1 and ADvocate2 trials were conjunctivitis (7 and 8%, respectively), nasopharyngitis (4 and 5%, respectively) and headache (3 and 5%, respectively). Results from clinical trials suggest that lebrikizumab may be a viable alternative for AD management.

Migraine constitutes the world's second-leading cause of disability. Triptans, as serotonin 5-HT 1B/1D receptor agonists, remain the first-line treatment, despite discouraged use in individuals at high cardiovascular risk. Lasmiditan, a selective lipophilic 5-HT 1F agonist without vasoconstrictive effects, is an emerging option. We aimed to investigate the safety profile of lasmiditan in the WHO pharmacovigilance database (VigiBase ® ) using a comparative disproportionality analysis with triptans. VigiBase ® was queried for all reports involving lasmiditan and triptans. Disproportionality analyses relied on the calculation of the information component (IC), for which 95% confidence interval (CI) lower bound positivity was required for signal detection. We obtained 826 reports involving lasmiditan. Overall, 10 adverse drug reaction classes were disproportionately reported with triptans, while only neurological (IC 1.6; 95% CI 1.5-1.7) and psychiatric (IC 1.5; 95% CI 1.3-1.7) disorders were disproportionately reported with lasmiditan. Sedation, serotonin syndrome, euphoric mood, and autoscopy had the strongest signals. When compared with triptans, 19 out of 22 neuropsychiatric signals persisted. The results of our analysis provide a more precise semiology of the neuropsychiatric effects of lasmiditan, with symptoms such as autoscopy and panic attacks. The cardiovascular adverse drug reaction risk with triptans was confirmed. In contrast, caution is warranted with lasmiditan use in patients with neurological or psychiatric comorbidities or serotonin syndrome risk. Our study was hindered by pharmacovigilance flaws, and further studies should help in validating these results. Our findings suggest that lasmiditan is a safe alternative for migraine treatment, especially when the neuropsychiatric risk is outweighed by the cardiovascular burden., (© 2023.

Rheumatoid arthritis (RA), a distressing inflammatory autoimmune disease, is managed mainly by Disease-modifying antirheumatic drugs (DMARDs), e.g. leflunomide (LEF). LEF (BCS class II) has limited solubility and adverse effects following its systemic exposure. The appealing antirheumatic properties of both clove oil and chitosan (CS) were exploited to design oral leflunomide (LEF)-loaded nanoemulsion (NE) system to augment the therapeutic action of LEF and decrease its systemic side effects as well. Different LEF-NEs were prepared using clove oil, Tween® 20 (surfactant), and PEG 400(co-surfactant) and characterized by thermodynamic stability, percentage transmittance, cloud point, size analysis, and drug content. Optimized LEF-NE was subjected to CS coating forming LEF-CS-NE that exhibited nanometric size range, prolonged drug release, and good physical stability. In vivo anti-rheumatic activity of pure LEF, market LEF, and LEF-CS-NE was assessed utilizing a complete Freund's adjuvant (CFA) rat model. Treatment with LEF-CS-NE reduced edema rate (48.68% inhibition) and caused a marked reduction in interleukin-6 (IL-6) (510.9 ± 2.48 pg/ml), tumor necrosis factor- α (TNF-α) (397.3 ± 2.53 pg/ml), and rheumatoid factor (RF) (42.58 ± 0.49 U/ml). Furthermore, LEF-CS-NE reduced serum levels of glutamic pyruvic transaminase (GPT) to (83.19%) and glutamic oxaloacetic transaminase (GOT) to (40.68%) compared to the control + ve group. The effects of LEF-CS-NE were also superior to both pure and market LEF and showed better results in histopathological studies of paws, liver, kidney, lung, and heart. The remarkable therapeutic and safety profile of LEF-CS-NE makes it a potential oral system for the management of RA., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Lacosamide (LCM) is a new-generation anti-seizure medication approved for monotherapy and add-on therapy for focal-onset epilepsy. It has novel pharmacodynamics and favorable pharmacokinetic qualities with good clinical response. This study aims to evaluate the effectiveness and tolerability of LCM when used in the immediate switch from sodium channel blockers in patients with focal-onset and generalized-onset epilepsies. This retrospective, multicenter observational study was conducted with adult patients who received LCM as mono- or polytherapy through immediate switch with 6 to 52 months follow-up. The clinical data obtained during the follow-up period were analyzed to assess retention rate, seizure freedom, more than 50% seizure reduction, and adverse effects. A total of 32 patients (eight females, 24 males) with a median age of 49.75 (range, 23-86) years, median age at epilepsy onset of 32.58 (range, 0.5-85) years, and median epilepsy duration of 17.17 (range, 1-46) years were included in this study. Seizure frequency was between 1 and 90 in the past 6 months. Seven (21.9%) of the patients had structural brain lesions and 27 (84.4%) of the patients had EEG abnormalities. The adverse effects leading to switching were hyponatremia, rash, elevated liver enzymes, pain, and erectile dysfunction. At 14.34 (range, 6-52) months follow-up, 30 (93.75%) patients in total retained LCM, 20 (66.7%) of them were seizure-free, and 13 were on LCM monotherapy. Responder rate was 81.25%. Eight (25%) of the patients experienced adverse effects after the immediate switch. One patient with generalized-onset epilepsy needed to quit LCM due to an increase in seizures. Seizure frequency did not change in three patients in the focal-onset group. Immediate switch to LCM showed favorable outcomes with a significant reduction in seizure frequency, high retention rates, and tolerable adverse effect profiles in both focal-onset and generalized-onset seizures., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Purpose: Clinical pharmacy can reduce drug-related iatrogenesis by improving the management of adverse effects of drugs, limiting drug-drug interactions, and improving patient adherence. Given the vulnerability of cancer patients and the toxicity of injectable anticancer drugs, clinical pharmacy service (CPS) could provide a significant clinical benefit in cancer care. This review aims to synthesize existing evidence on clinical pharmacy's impact on patients treated with intravenous anticancer drugs., Methods: A comprehensive search was performed in the PubMed/Medline database from January 2000 to December 2021, associating the keywords: clinical pharmacy, pharmaceutical care, pharmacist, oncology, and chemotherapy. To be eligible for inclusion, studies have to report clinical pharmaceutical services for patients treated with intravenous chemotherapy with a clinical and/or economic impact., Results: Forty-one studies met the selection criteria. Various CPS were reported: medication reconciliation, medication review, and pharmaceutical interview with patient. There was a lack of randomized study (n = 3; 7.3%). In one randomized controlled trial, pharmaceutical intervention significantly improved quality of life of patients receiving pharmaceutical care during injectable anticancer drugs courses. Economical results appear to show positive impact of clinical pharmacy with cost savings reported from 3112.87$ to 249 844€. Although most studies were non-comparative, they highlighted that clinical pharmacy tend to limit chemotherapy side effects and drug-related problems, improve quality of life and satisfaction of patients and healthcare professional, and a positive economic impact., Conclusion: Clinical pharmacy can reduce adverse drug events in cancer patients. More robust and economic evaluations are still required to support its development in everyday practice., (© 2023.

Purposes: In patients with advanced lung cancer, immune checkpoint inhibitors (ICIs) dramatically extended survival. We aimed to investigate the experiences of patients with advanced lung cancer who are receiving ICIs, with a focus on perceptions and sentiments on ICIs, to inform future research and clinical care., Methods: Patients were recruited from January to July 2022 at Tianjin Medical University Hospital Cancer Institute & Hospital. The method of purposive sampling was used. Patients with stage IV lung cancer who were taking ICIs as a single therapy were recruited. Data were gathered using semi-structured and face-to-face interview. An inductive approach to analysis was used., Results: Of the 42 eligible patients, 27 were invited, 20 agreed to participate, and ultimately 17 patients completed the interview. A total of 5 themes were extracted: suffered from adverse effects but generally tolerable; focus on survival, hope, and expectation; uncertainty about durability of response and the future; poor knowledge and attitude of ICIs; and financial stress and guilt over family., Conclusion: These findings make an important contribution to healthcare professionals' understanding of what it is like to be a patient with advanced lung cancer who is receiving ICIs. In general, the experience of immunotherapy is different from that of chemotherapy; financial and family pressures and uncertainty issues are likely to be heavier in this population. Oncology specialist nurses should provide tailored education to improve the patient's knowledge of immunotherapy, especially to improve risk awareness of immune-related adverse events and objective prognosis expectations., (© 2023.

Since their invention in the early 2000s, tyrosine kinase inhibitors (TKIs) have gained prominence as the most effective pathway-directed anti-cancer agents. TKIs have shown significant utility in the treatment of multiple hematological malignancies and solid tumors, including chronic myelogenous leukemia, non-small cell lung cancers, gastrointestinal stromal tumors, and HER2-positive breast cancers. Given their widespread applications, an increasing frequency of TKI-induced adverse effects has been reported. Although TKIs are known to affect multiple organs in the body including the lungs, liver, gastrointestinal tract, kidneys, thyroid, blood, and skin, cardiac involvement accounts for some of the most serious complications. The most frequently reported cardiovascular side effects range from hypertension, atrial fibrillation, reduced cardiac function, and heart failure to sudden death. The potential mechanisms of these side effects are unclear, leading to critical knowledge gaps in the development of effective therapy and treatment guidelines. There are limited data to infer the best clinical approaches for the early detection and therapeutic modulation of TKI-induced side effects, and universal consensus regarding various management guidelines is yet to be reached. In this state-of-the-art review, we examine multiple pre-clinical and clinical studies and curate evidence on the pathophysiology, mechanisms, and clinical management of these adverse reactions. We expect that this review will provide researchers and allied healthcare providers with the most up-to-date information on the pathophysiology, natural history, risk stratification, and management of emerging TKI-induced side effects in cancer patients., (© 2023.
