Practical Relevance: Acid-related disorders including esophagitis and gastroduodenal ulceration are uncommon in the cat. However, when they occur, they can have devastating consequences and require targeted intervention, including the use of gastroprotectants. Careful consideration of the causes of esophagitis and gastroduodenal ulceration can help the clinician to determine which gastroprotectant to use, and when to begin and end gastroprotective therapy., Clinical Challenges: Gastroprotectants remain one of the most misused classes of drugs in veterinary and human medicine. There are very few studies evaluating the efficacy of gastroprotective agents in cats. Furthermore, goals for the degree of gastric acid suppression are extrapolated from studies performed in dogs and humans., Aims: This review provides a foundation for the logical approach to the choice of gastroprotectant as indicated by the disease process, and is aimed at all veterinarians who prescribe gastroprotectants for use in cats., Evidence Base: The guidance provided in this review is supported by current literature, including consensus opinion from the American College of Veterinary Internal Medicine. Gaps in evidence for use of gastroprotectants in cats are filled by extrapolations from studies performed in dogs and humans., Competing Interests: Conflict of interestKatie Tolbert is a scientific advisor for TriviumVet, the manufacturer of omepraVet (although this product has only been studied in dogs).

Patients with Crohn's disease are at higher risk of opportunistic infection, especially if treated with immunosuppressive therapy. Cytomegalovirus has been reported to cause ulcerated lesions mainly in the lower gastrointestinal tract of inflammatory bowel disease patients. We herein report a rare case of Crohn's disease complicated with cytomegalovirus esophagitis, which was difficult to distinguish from exacerbation of Crohn's disease. Diagnostic values of clinical course, blood tests, endoscopic and histological examinations are limited but the present case was therapeutically diagnosed by antiviral therapy in combination with histological evidence of cytomegalovirus., (© 2024.

Background and Aim: Healing rates of severe erosive esophagitis (EE; Los Angeles [LA] Grade C/D) in patients treated with a proton pump inhibitor (PPI) is suboptimal (~60-70%). Vonoprazan, a potassium-competitive acid blocker, is suggested to have better healing rates in patients with severe EE. This meta-analysis compares the efficacy and safety of vonoprazan 20 mg versus lansoprazole 30 mg daily in healing EE, specifically in those with LA Grade C/D., Methods: We searched MEDLINE, Embase, and CENTRAL on May 24, 2023. Studies that randomized EE patients to vonoprazan 20 mg daily or lansoprazole 30 mg daily and compared healing rates were included. The risk of bias was assessed using Cochrane's Risk of Bias 2 tool. The fixed-effect model was used to obtain the pooled efficacy and safety outcomes. Subgroup analysis was done to compare healing rates in mild (LA Grade A/B) versus severe EE and based on study location., Results: Four randomized controlled trials (RCTs) with low risks of bias comprising 2208 participants were included. Vonoprazan 20 mg was superior to lansoprazole 30 mg daily in healing severe EE at all weeks (Week 2 RR 1.294 [95% CI 1.169-1.433], Week 4 1.160 [1.059-1.270], and Week 8 1.175 [95% CI 1.107-1.247]), but was similar for mild EE at all weeks (P-interaction < 0.01). Vonoprazan 20 mg was more efficacious than lansoprazole 30 mg at Week 8 in Western versus Asian studies (P-interaction < 0.01). Any, serious, and drug-related treatment-emergent adverse events were comparable between groups., Conclusion: Vonoprazan 20 mg is superior to lansoprazole 30 mg for healing severe EE but not mild EE. Vonoprazan 20 mg daily has a similar safety profile to lansoprazole 30 mg daily., (© 2024 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Introduction: Los Angeles grade C/D esophagitis is a severe manifestation of gastroesophageal reflux disease that require active treatment and close follow-up. Potassium competitive acid blockers (P-CAB) are promising alternatives to proton pump inhibitors (PPI). We aimed to compare the efficacy and safety of P-CAB and PPI in healing grade C/D esophagitis to aid clinical decision-making., Methods: A systematic literature search was performed using PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials were eligible for inclusion if efficacy of P-CAB and PPI in healing grade C/D esophagitis was reported. Pooled risk ratios and risk difference with 95% credible intervals were used to summarize estimated effect of each comparison. The benefit of treatments was ranked using the surface under the cumulative probability ranking score., Results: Of 5,876 articles identified in the database, 24 studies were eligible. Studies included incorporated 3 P-CAB (vonoprazan, tegoprazan, and keverprazan) and 6 PPI (lansoprazole, esomeprazole, omeprazole, rabeprazole extended-release (ER), pantoprazole, and dexlansoprazole). Based on the failure to achieve mucosal healing, 20 mg of vonoprazan q.d. ranked the first among PPI in initial and maintained healing of grade C/D esophagitis (surface under the cumulative probability ranking score = 0.89 and 0.87, respectively). Vonoprazan had similar risk of incurring adverse events, severe adverse events, and withdrawal to drug when compared with PPI. For those who attempted lower maintenance treatment dose, 10 mg of vonoprazan q.d. was a reasonable choice, considering its moderate efficacy and safety., Discussion: Vonoprazan has considerable efficacy in initial and maintained healing of grade C/D esophagitis compared with PPI, with moderate short-term and long-term safety., (Copyright © 2024 by The American College of Gastroenterology.)

Data for pharmacologic treatments for non-eosinophilic esophagitis (EoE) eosinophilic gastrointestinal diseases (EGIDs) are limited. Nevertheless, because of the increasing understanding of EGID pathogenesis, a number of medications are used to treat EGIDs, though all are currently off-label. Initial therapy generally starts with corticosteroids, and "topical" delivery is preferred over systemic due to long-term side effects. A number of other small molecules could potentially be used, ranging from allergy medications to immunosuppressants. Biologics are also being used and investigated for EGIDs and represent promising targeted therapies. Multiple therapeutic targets have also been identified, many of which overlap with EoE targets., Competing Interests: Disclosure E.S.

Background: Erosive esophagitis (EE) is a gastroesophageal reflux disease characterized by mucosal breaks in the esophagus. Proton pump inhibitors are widely used as maintenance therapy for EE, but many patients still relapse. In this trial, we evaluated the noninferiority of vonoprazan vs. lansoprazole as maintenance therapy in patients with healed EE., Methods: We performed a double-blind, double-dummy, multicenter, phase 3 clinical trial among non-Japanese Asian adults with endoscopically confirmed healed EE from April 2015 to February 2019. Patients from China, South Korea, and Malaysia were randomized to vonoprazan 10 mg or 20 mg once daily or lansoprazole 15 mg once daily for 24 weeks. The primary endpoint was endoscopically confirmed EE recurrence rate over 24 weeks with a noninferiority margin of 10% using a two-sided 95% confidence interval (CI). Treatment-emergent adverse events (TEAEs) were recorded., Results: Among 703 patients, EE recurrence was observed in 24/181 (13.3%) and 21/171 (12.3%) patients receiving vonoprazan 10 mg or 20 mg, respectively, and 47/184 (25.5%) patients receiving lansoprazole (differences: -12.3% [95% CI, -20.3% to -4.3%] and -13.3% [95% CI, -21.3% to -5.3%], respectively), meeting the primary endpoint of noninferiority to lansoprazole in preventing EE recurrence at 24 weeks. Evidence of superiority (upper bound of 95% CI <0%) was also observed. At 12 weeks, endoscopically confirmed EE recurrence was observed in 5/18, 2/20, and 7/20 of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. TEAEs were experienced by 66.8% (157/235), 69.0% (156/226), and 65.3% (158/242) of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. The most common TEAE was upper respiratory tract infection in 12.8% (30/235) and 12.8% (29/226) patients in vonoprazan 10 mg and 20 mg groups, respectively and 8.7% (21/242) patients in lansoprazole group., Conclusion: Vonoprazan maintenance therapy was well-tolerated and noninferior to lansoprazole for preventing EE recurrence in Asian patients with healed EE., Trial Registration: https://clinicaltrials.gov; NCT02388737., (Copyright © 2024 The Chinese Medical Association, produced by Wolters Kluwer, Inc. under the CC-BY-NC-ND license.)

Infectious esophagitis (IE) is the leading cause of esophagitis, second only to gastroesophageal reflux disease. Infectious esophagitis is typically observed in immunocompromised individuals due to neutropenia, HIV/AIDS, solid organ malignancies, cancer-directed therapy, or chronic steroid use. The most common causes of IE are herpes simplex virus (HSV), cytomegalovirus (CMV), and Candida albicans . Acute bacterial esophagitis is exceedingly rare, particularly in immunocompetent patients. Herein, we describe a unique case of acute streptococcal esophagitis in a male patient with no pertinent medical history. The patient's substernal chest pain and odynophagia resolved after antibiotic treatment., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Herpetic esophagitis (HE) is common in immunocompromised patients but rarely reported in healthy young adults. A 28-year-old healthy male patient visited our clinic with a chief complaint of chest pain. An esophagogastroduodenoscopy revealed widely spread superficial multiple ulcers in the middle to the distal esophagus, and repeated biopsies from the ulcer were performed but revealed inconsistent findings with HE. Thus, he was clinically diagnosed with HE based on endoscopic findings and serologic tests of immunoglobulin M (IgM)/immunoglobulin G (IgG) for herpes simplex virus. He responded to valacyclovir, and all esophageal ulcers had scarred., (© 2023. Japanese Society of Gastroenterology.)

Introduction: Erosive esophagitis (EE) is a severe form of gastroesophageal reflux disease commonly treated with proton pump inhibitors (PPIs). The aim of this retrospective, observational cohort study was to describe the characteristics and healthcare burden of patients with EE., Methods: We identified adults in the USA with an EE diagnosis between January  1, 2016 and February 28, 2019 in a linked dataset containing electronic health records (EHR) from the Veradigm Network EHR and claims data from Komodo Health. Patients were required to have 1 year of baseline data and 3 years of follow-up data. Patients were stratified by the number of PPI lines of therapy (LOT) during the 4-year study period. We descriptively captured patient characteristics and treatment patterns, along with all-cause and EE-related healthcare utilization and costs., Results: Among the 158,347 qualifying adults with EE, 71,958 (45.4%) had 1 PPI LOT, 14,985 (9.5%) had 2 LOTs, 15,129 (9.6%) had 3+ LOTs, and 56,275 (35.5%) did not fill a PPI prescription. Omeprazole and pantoprazole comprised more than 70% of any LOT, with patients commonly switching between the two. Mean (standard deviation) annualized all-cause and EE-related healthcare costs in the follow-up period were $16,853 ($70,507) and $523 ($3659), respectively. Both all-cause and EE-related healthcare costs increased with LOTs., Conclusions: Patients with EE are commonly treated with prescription PPIs; however, 19.0% of patients cycled through multiple PPIs. Higher PPI use was associated with a higher comorbidity burden and higher healthcare costs compared to 0 PPI use., (© 2023. The Author(s).)

The purpose is to compare the clinical efficacy and toxicity of etoposide plus lobaplatin (EL) or etoposide plus cisplatin (EP) with concurrent thoracic radiotherapy during the treatment of limited-stage small cell lung cancer (LS-SCLC). Forty-two patients with LS-SCLC were randomly divided into EL ( n = 19) or EP ( n = 23) regimens combined with thoracic intensity-modulated radiotherapy. The primary endpoint was 1-year progression-free survival (PFS) rate. The 1-, 2-, and 3-year PFS rates in the EL and EP cohorts were 50.8, 38.1, and 12.7%; and 56.5, 43.5, and 29.0%, respectively ( P = 0.527), whereas the 1-, 2-, and 3-year overall survival (OS) rates were 72.2, 52.5, and 43.8%; and 73.9, 48.4, and 48.4%, respectively ( P = 0.923). The hematological toxicities were similar in two cohorts. However, gastrointestinal reactions were more severe in the EP group. The incidence of nausea and vomiting in EL and EP cohorts were 31.6% vs. 73.9% ( P = 0.006) and 20.1% vs. 60.9% ( P = 0.009), respectively. The two cohorts did not show ≥grade 4 radiation esophagitis and ≥grade 3 radiation pneumonitis. The incidence of acute radiation esophagitis in EL group was lower ( P = 0.038), both groups showed a similar incidence of radiation pneumonitis ( P = 1.000). EL or EP chemotherapy with concurrent thoracic radiotherapy showed similar PFS and OS. The EL group showed milder gastrointestinal toxicity and radiation esophagitis. Radiation pneumonitis and hematological toxicity were similar in the two regimens, which can be tolerated by patients., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Currently, radiation therapy treatment planning system intends biological optimization that relies heavily upon plan metrics from tumor control probability (TCP) and normal tissue complication probability (NTCP) modeling. Implementation and expansion of TCP and NTCP models with alternative data is an important step towards reliable radiobiological treatment planning. In this retrospective single institution study, the treatment charts of 139 lung cancer patients treated with chemo-radiotherapy were reviewed and correlated dosimetric predictors with the incidence of esophagitis and established NTCP model of esophagitis grade 1 and 2 for lung cancer patients., Methods: Esophagus is an organ at risk (OAR) in lung cancer radiotherapy (RT). Esophagitis is a common toxicity induced by RT. In this study, dose volume parameters V x (V x : percentage esophageal volume receiving ≥ x Gy) and mean esophagus dose (MED) as quantitative dose-volume metrics, the esophagitis grade 1 and 2 as endpoints, were reviewed and derived from the treatment planning system and the electronic medical record system. Statistical analysis of binary logistic regression and probit were performed to have correlated the probability of grade 1 and 2 esophagitis to MED and V x . IBM SPSS software version 24 at 5% significant level (α = 0.05) was used in the statistical analysis., Results: The probabilities of incidence of grade 1 and 2 esophagitis proportionally increased with increasing the values of V x and MED. V 20 , V 30 , V 40 , V 50 and MED are statistically significant good dosimetric predictors of esophagitis grade 1. 50% incidence probability (TD 50 ) of MED for grade 1 and 2 esophagitis were determined. Lyman Kutcher Burman model parameters, such as, n, m and TD 50 , were fitted and compared with other published findings. Furthermore, the sigmoid shaped dose responding curve between probability of esophagitis grade 1 and MED were generated respecting to races, gender, age and smoking status., Conclusions: V 20 , V 30 , V 40 and V 50 were added onto Quantitative Analysis of Normal Tissue Effects in the clinic, or QUANTEC group's dose constrains of V 35 , V 50 , V 70 and MED. Our findings may be useful as both validation of 3-Dimensional planning era models and also additional clinical guidelines in treatment planning and plan evaluation using radiobiology optimization., (© 2023.

Proton pump inhibitors (PPIs) are a mainstay treatment for acid peptic disorders such as gastroesophageal reflux disease (GERD). Although PPIs are considered first-line medications for acid suppression, they have notable limitations such as requiring acid-mediated activation, short half-life and duration of action, and metabolic variability. Fexuprazan is a newly developed potassium-competitive acid blocker (P-CAB), which inhibits acid generation and secretion in a competitive and reversible manner. Fexuprazan, like other P-CABs, has significantly different pharmacodynamic and pharmacokinetic properties than PPIs with potential advantages including rapid, robust, and durable acid suppression, lack of CYP2C19 metabolism, independence from food intake, and no requirement for activation into an active form. Completed clinical trials of fexuprazan have demonstrated comparable efficacy to PPIs for the healing of erosive esophagitis and relief of GERD-related esophageal symptoms without concerning safety signals. Ongoing clinical trials are evaluating fexuprazan for the prevention of NSAID-induced peptic ulcer disease, non-erosive GERD, and acute and chronic gastritis, as well as healing efficacy and maintenance of erosive esophagitis (EE). Fexuprazan is approved in South Korea for the treatment of EE and at the time of this writing is being considered for regulatory approval in several other countries. In this article, we summarize and discuss the pharmacology, efficacy, and safety of fexuprazan., (© 2023.

Background: Treatment of acid-related disorders relies on gastric acid suppression. The percentage of time intragastric pH is >4 (pH >4 holding time ratio [HTR]) is important for healing erosive oesophagitis; and the pH >6 HTR is critical for eradication of Helicobacter pylori infection, as bacterial replication is active and antibiotic effectiveness is optimised. Vonoprazan, a potassium-competitive acid blocker approved in the USA and other countries, suppresses gastric acid secretion in a predictable, rapid and consistent manner, extended over prolonged periods., Aim: To explore the relationship between vonoprazan exposure and pH HTR through a pharmacokinetic/pharmacodynamic (PK/PD) model., Methods: We pooled data from Phase 1 studies with intragastric pH measurements. Pharmacokinetic profiles were predicted for study participants using an existing population pharmacokinetic model. Pharmacokinetic and pharmacodynamic data were merged, and three direct-link PK/PD models were derived and used to simulate pH HTRs with between-participant variability for pH >4, >5 and >6, for vonoprazan doses of 20 mg once and twice daily., Results: We used data from five Phase 1 studies to derive the PK/PD model. These included 245 participants (95.1% male, 50.6% Japanese and 49.4% non-Asian). Pre-dose, the mean pH >4 HTR was 6.4%, pH >5 3.2% and pH >6 1.2%. After 7 days of dosing, simulations predicted pH >4 HTRs of 89.7% and 98.1%, and pH >6 HTRs of 53.1% and 75.3%, for vonoprazan 20 mg once and twice daily, respectively., Conclusions: Vonoprazan 20 mg once- and twice-daily dosing demonstrated high, dose-dependent, 24-hour intragastric acid control in this PK/PD model, supporting clinical efficacy data in patients with acid-related disorders., (© 2023 The Authors.

Tetracyclines are a class of broad-spectrum bacteriostatic antibiotics used to treat many infections, including methicillin-resistant Staphylococcus aureus (MRSA), acne, pelvic inflammatory disease, chlamydial infections, and a host of zoonotic infections. These drugs work by inhibiting protein synthesis in bacterial ribosomes, specifically by disallowing aminoacyl-tRNA molecules from binding to the ribosomal acceptor sites. While rare, tetracycline antibiotics, particularly minocycline and doxycycline, are associated with an increased risk of developing esophageal perforation and pseudotumor cerebri (PTC, or idiopathic intracranial hypertension). Since tetracyclines are a commonly prescribed class of medications, especially in adolescents for acne treatment, it is important for clinicians to appreciate significant side effects that can result in morbidity and mortality. This paper aims to consolidate and to emphasize current research on the association between tetracycline antibiotics and the development of esophageal perforation, and PTC. PTC is a neurological syndrome consisting of increased intracranial pressure, headache, and vision changes without evidence of the contributing source, such as mass lesion, infection, stroke, or malignancy. Esophageal perforation, while rare, can be the result of pill esophagitis. Pill-induced injuries occur when caustic medicinal pills dissolve in the esophagus rather than in the stomach. Most patients experience only self-limited pain (retrosternal burning discomfort, heartburn, dysphagia, or odynophagia), but hemorrhage, stricture, and perforation may occur. Tetracycline use can lead to pill esophagitis. In summary, clinicians should appreciate the potential risks of tetracycline compounds in clinical practice., (© 2023.

Introduction: Doxycycline is an antibiotic with known gastrointestinal (GI) adverse effects. Esophagitis is the most pronounced among these effects, and might be associated with a prolonged duration of therapy. The aim of this study is to evaluate the incidence of esophagitis and other GI side effects in adults who received doxycycline for at least a month., Methodology: This retrospective descriptive study included adults who received oral doxycycline for at least one month between 2016 and 2018. The primary outcome was the frequency of esophagitis. The secondary outcomes were frequency of and discontinuation due to GI adverse effects., Results: A total of 189 subjects were included with a median age of 32 years. The median duration of doxycycline use was 44 days (interquartile range 30-60). Twelve patients (6.3%) reported having GI adverse effects resulting in doxycycline discontinuation in five of them (2.6%), and three patients (1.6%) had esophagitis. The incidence of GI adverse effects was significantly higher in patients who were ≥ 50 years than < 50 years old (8/50 vs. 4/139; p = 0.003) and in those who received a daily dose of 200 mg than 100 mg (12/93 vs. 0/96; p < 0.001)., Conclusions: GI adverse events, including esophagitis, are not rare with long-term use of oral doxycycline, particularly in older age and a higher dose of 200 mg/day. Future large and randomized studies are needed to compare the efficacy and safety of different doxycycline doses., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2023 Khalid Eljaaly, Haifa Alghamdi, Hadeel Almehmadi, Fahad Aljawi, Ammar Hassan, Abrar K Thabit.)

A recent report showed that most pediatric cases of non-eosinophilic esophagitis (EoE) eosinophilic gastrointestinal disorders (EGIDs) (non-EoE EGIDs) are persistent and severe compared with those of EoE, thus requiring further effective therapeutic approaches. In this study, we present the first case based on a systematic search of non-EoE EGID for which tolerance to causative foods and histological and symptomatic improvements were achieved following dupilumab administration, after elimination diets and omalizumab and mepolizumab treatments. Driven by this case, we investigated the efficacies of biological treatments in non-EoE EGID cases based on the patient studied herein, and other patients identified in the conducted systematic review. Seven articles, including five different biologics, were reviewed. Both clinical efficacies and impact differences among the targeted molecules are demonstrated in this study. Our findings show that dupilumab may affect mechanisms that can suppress symptoms induced by offending foods that are different from those induced by other biologics as identified in the conducted systematic review. Additional studies are required to address the unmet needs of non-EoE EGID treatments.

Background: Bisphosphonates are the mainstay of osteoporosis treatment, but their use for patients with esophageal varices has been avoided due to the risk of esophagitis, which may cause variceal bleeding. Since most clinical trials assessing osteoporosis treatment last 2-3 years, this study aimed to evaluate a 2-year risedronate treatment for patients with esophageal varices and liver cirrhosis., Methods: The study received Institutional Review Board approval, and the sample was divided into two groups according to bone mineral density (BMD). Cirrhosis severity and endoscopic findings at baseline were similar between the groups. The intervention group had 51 patients with osteoporosis, who received oral risedronate 35 mg weekly plus calcium and vitamin D supplements. The control group had 51 patients with osteopenia, receiving only the supplements. Scheduled esophagogastroduodenoscopies and BMD measurements were carried out., Results: The adjusted esophagitis risk was higher in the intervention group; however, none of the subjects had digestive bleeding. Lumbar spine BMD increased in the intervention group (- 3.06 ± 0.71 to - 2.33 ± 0.90; p < 0.001) and in the control group (- 1.38 ± 0.77 to - 1.10 ± 1.05; p = 0.012). Femoral neck BMD did not change in the intervention group (- 1.64 ± 0.91 to - 1.71 ± 0.95; p = 0.220), but tended to decrease in the control group (- 1.00 ± 0.74 to - 1.09 ± 0.82; p = 0.053)., Conclusion: Oral risedronate was effective and did not cause gastrointestinal bleeding in cirrhotic patients with esophageal varices under endoscopic surveillance., (© 2022.

Background: Opportunistic infections are frequent in people living with the human immunodeficiency virus who either do not have access to antiretroviral therapy (ART) or use it irregularly. Tuberculosis is the most frequent infectious disease in PLHIV and can predispose patients to severe fungal infections with dire consequences., Case Presentation: We describe the case of a 35-year-old Brazilian man living with human immunodeficiency virus (HIV) for 10 years. He reported no adherence to ART and a history of histoplasmosis with hospitalization for 1 month in a public hospital in Natal, Brazil. The diagnosis was disseminated Mycobacterium tuberculosis infection. He was transferred to the health service in Recife, Brazil, with a worsening condition characterized by daily fevers, dyspnea, pain in the upper and lower limbs, cough, dysphagia, and painful oral lesions suggestive of candidiasis. Lymphocytopenia and high viral loads were found. After screening for infections, the patient was diagnosed with tuberculous pericarditis and esophageal candidiasis caused by Candida tropicalis. The isolated yeasts were identified using the VITEK 2 automated system and matrix-assisted laser desorption/ionization time-of-flight-mass spectrometry. Antifungal microdilution broth tests showed sensitivity to fluconazole, voriconazole, anidulafungin, caspofungin, micafungin, and amphotericin B, with resistance to fluconazole and voriconazole. The patient was treated with COXCIP-4 and amphotericin deoxycholate. At 12 days after admission, the patient developed sepsis of a pulmonary focus with worsening of his respiratory status. Combined therapy with meropenem, vancomycin, and itraconazole was started, with fever recurrence, and he changed to ART and tuberculostatic therapy. The patient remained clinically stable and was discharged with clinical improvement after 30 days of hospitalization., Conclusion: Fungal infections should be considered in patients with acquired immunodeficiency syndrome as they contribute to worsening health status. When mycoses are diagnosed early and treated with the appropriate drugs, favorable therapeutic outcomes can be achieved., (© 2022. The Author(s).)

Aim: To evaluate the advantages of using combined therapy of proton-pump inhibitors (PPIs) and esophagoprotector in comparison with basic therapy of PPIs for 4 weeks based on the results of changes in the endoscopic picture.To compare the effectiveness of 4-week PPI therapy and 4-week combination therapy with PPI and esophagoprotector Alfasoxx (sodium hyaluronate, chondroitin sulfate, poloxomer 407) in patients with erosive esophagitis (EE) of any degree according to the Los Angeles Endoscopic Classification., Materials and Methods: 81 patients with EE AC according to the Los Angeles endoscopic classification (1994) was enrolled in the study on the basis of the clinic of Peter the Great, Mechnikov North-Western State Medical University. By computer randomization, patients were divided into the control group 40 patients (pantoprazole 40 mg 1 time per day) and the intervention group 41 patients (pantoprazole 40 mg 1 time per day + Alfasoxx 1 sachet qid). The therapy was carried out for 4 weeks. In all patients before and after therapy, the frequency and severity of the main symptoms of gastroesophageal reflux disease (GERD) were assessed, esophagogastroduodenoscopy was performed., Results: The advantage of combination therapy over standard PPI monotherapy in patients with EE was revealed. According to the results of the control endoscopy, healing of erosions of the esophageal mucosa was observed in 39 out of 41 (95.1%) patients in the intervention group and 32 out of 39 (82.1%) in the control group. The proportion of patients who showed an improvement in the endoscopic picture before and after treatment for 4 weeks by at least 1 level according to the Los Angeles classification was significantly higher in the comparison group 41 patients (100%), while in the control group 33 patients (85%); p0.009. After treatment, the combination therapy group had a lower incidence (p0.01) and severity of heartburn (p0.01). The same results are demonstrated by combination therapy regarding the symptom belching of air: in the study group after treatment, this symptom occurred less frequently (p=0.014), its severity was significantly less than in the control group (p0.01). There was a statistically significant decrease in the need for on-demand antacid therapy in the study group., Conclusion: In this study involving 81 patients with erosive GERD, the benefits of combination therapy were demonstrated. The addition of Alfasoxx medical device to PPI therapy increases the clinical and endoscopic efficacy of therapy. This positive effect is associated with the esophagoprotective properties of the drug, based on unique pharmacodynamic characteristics. Combination therapy for GERD is preferred in patients with EE. Studies have shown the expediency of using Alfasoxx in case of insufficient effectiveness of classical acid-suppressive therapy for GERD.

Introduction: Erosive esophagitis (EE) occurs when refluxate from the stomach causes T-lymphocyte infiltration of the esophageal mucosa, resulting in mucosal breaks. Currently, therapy with proton-pump inhibitors (PPIs) is the standard treatment for EE in the United States, but few comprehensive reviews exist on the efficacy of PPIs in US populations. Here, we present the most contemporary, thorough analysis of PPI efficacy rates, and identify and characterize patient subgroups at risk for poor healing outcomes., Areas Covered: We searched the literature to identify studies reporting rates of endoscopic healing and maintained healing of EE with PPI therapies in the US and found a paucity of recent evidence and real-world evidence. Twenty-two studies from 2009 and earlier were included in the final dataset., Expert Opinion: Rates of EE healing with PPIs were highest after 8 weeks of treatment, with over 80% of patients in most treatment arms demonstrating endoscopic healing, compared to lower efficacy (<80%) at 4 weeks. Rates of maintained healing with PPIs at 6 and 12 months were mostly lower than 80%, although the data were limited. Symptomatic patients and those with severe EE were less likely to achieve healing. Obese patients experienced similar healing rates as non-obese patients.

Background: Standard treatment for locally advanced non-small cell lung cancer (LA-NSCLC) is concomitant chemoradiotherapy. The survival benefit of combined treatment is partially counterbalanced by an increased rate of acute esophageal toxicity. Several pharmaceutical products are available for prevention and management of esophagitis, including Faringel Plus., Aim: To assess the incidence and the grade, identify the correlations with clinical, dosimetric, and therapeutic variables, and analyse the role of Faringel Plus as a pharmaceutical preventive measure against acute esophageal toxicity., Methods: Patients with LA-NSCLC treated with concomitant radiochemotherapy were retrospectively reviewed. Acute esophagitis and dysphagia were graded according to Common Terminology Criteria for Adverse Events version 5.0. Clinical, dosimetric, and therapeutic correlations were investigated using χ 2 test., Results: Among the 23 analysed patients, 18 (78.3%) and 1 (4.3%) developed G2 and G3 esophagitis, respectively; G1-2 dysphagia were reported in 11 cases (47.8%). No statistically significant correlation between the variables considered and acute esophageal toxicity was identified. In the group of patients who received Faringel Plus as preventive treatment (10 subjects, 43.5%), dysphagia presentation time was significantly longer ( p = 0.038); esophagitis onset time was longer and symptoms duration was shorter. Faringel Plus allowed a reduction in the use of analgesic drugs., Conclusions: Acute mild esophageal toxicity was confirmed to be a common side effect in this setting. No clinical-dosimetric parameter has been demonstrated to be effective in predicting acute esophageal toxicity. The use of Faringel Plus appears effective as a therapeutic and prophylactic tool to manage acute esophageal toxicity.

This article presents a case of successful treatment of severe erosive esophagitis, which developed after total gastrectomy. The patient suffered from a poorly differentiated, diffuse gastric carcinoma with subtotal gastric outlet obstruction, accompanied by Helicobacter pylori-associated type b gastritis. A few weeks after Helicobacter eradication followed by successful surgery, swallowing of nutrition became impossible due to severe erosive esophagitis. Histologically there was no evidence of tumor infiltration in this organ. After numerous unsuccessful attempts using established conventional pharmacotherapy options, the problem could be solved by daily subcutaneous somatostatin-analogue (octreotide) injections. The patient started to eat again, and endoscopically/histologically the severe inflammation significantly improved. Attempts to reduce the daily injections, undertaken by the patient, resulted in relapses within a few days. Octreotide was well tolerated by the patient., (© 2022.

Candida nivariensis caused refractory esophagitis in a 36-year-old Brazilian man coinfected with HIV and Leishmania . A literature review on this rare fungal pathogen is also presented. The diagnosis was made, and pathogen identification was performed using matrix-assisted laser desorption ionization-time of flight mass spectrometry and sequencing of the LSU/26S region. An antifungigram was performed using broth microdilution. A literature search of PubMed was performed. The causative agent, C. nivariensis , was resistant to fluconazole and voriconazole. The patient's condition worsened considerably, and he passed away. This is the second report of this Candida species in Brazil and the first case reported worldwide of refractory esophagitis in a patient coinfected with HIV and Leishmania . The case illustrates the importance of precise identification and antifungal susceptibility testing when isolating this emerging pathogen.

Objective: Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting., Design: US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records., Results: 102 GIs and 149 FPs/GPs completed the survey; data were available for 73 patients (mean age at diagnosis, 45.4 years). Omeprazole was healthcare professional (HCP)-preferred first-line treatment (60.8% GIs; 56.4% FPs/GPs), and pantoprazole preferred second line (29.4% and 32.9%, respectively). Price and insurance coverage (both 55.5% HCPs) and familiarity (47.9%) key drivers for omeprazole; insurance coverage (52.0%), price (50.0%), familiarity (48.0%), initial symptom relief (46.0%), and safety (44.0%) key drivers for pantoprazole. Only 49.3% patients took medication as instructed all the time; 56.8% independently increased medication frequency some of the time. Despite treatment, 57.5% patients experienced heartburn and 30.1% regurgitation; heartburn was the most bothersome symptom. 58.9% patients believed that their symptoms could be better controlled; only 28.3% HCPs were very satisfied with current treatment options. 83.6% patients wanted long-lasting treatment options. Fast symptom relief for patients was a top priority for 66.1% HCPs, while 56.6% would welcome alternatives to PPIs., Conclusion: This real-world multicentre study highlights the need for new, rapidly acting treatments in EE that reduce symptom burden, offer durable healing and provide symptom control., Competing Interests: Competing interests: CP and RJ are employees of Phathom Pharmaceuticals.

Goals: This systematic review and network meta-analysis aimed to assess the relative efficacy of vonoprazan and proton pump inhibitors (PPIs) on early heartburn symptom resolution in patients with erosive esophagitis., Background: Limited available data directly compare the efficacy of vonoprazan, a first-in-class potassium-competitive acid blocker, with PPIs in erosive esophagitis., Study: We conducted a systematic literature review (in MEDLINE and CENTRAL) and subsequent network meta-analysis according to Cochrane and PRISMA guidelines. Double-blind, randomized controlled trials in adults with erosive esophagitis treated with vonoprazan or a PPI were included in the analysis. Primary outcomes were heartburn symptom resolution rate on Day 1 and Day 7. The study was performed with all available data, using a random effects model within a Bayesian framework., Results: Overall, 10 randomized controlled trials were included in the network meta-analysis. For heartburn resolution rate on Day 1 (9 of 10 trials), vonoprazan 20 mg once daily (QD) was superior to placebo (median odds ratio=16.75, 95% credible interval: 2.16-207.80). Point estimates numerically favored vonoprazan 20 mg QD over other comparators. For heartburn resolution rate on Day 7 (10 of 10 trials), vonoprazan 20 mg QD was superior to placebo and other comparators except rabeprazole 20 mg QD. Point estimates numerically favored vonoprazan 20 mg QD over rabeprazole 20 mg QD., Conclusions: In this study, vonoprazan 20 mg QD was equally effective in heartburn resolution on Day 1, and equally or more effective on Day 7 versus PPIs in adults with erosive esophagitis., (Copyright © 2022 The Author(s).

Vonoprazan, a potassium-competitive acid blocker, is under investigation in the United States and Europe for the treatment of erosive esophagitis and Helicobacter pylori infection. Population pharmacokinetic (popPK) analysis allows the identification of factors that could affect drug exposure in population subgroups. Here, we report a popPK model based on pooled data sets of available pharmacokinetic (PK) studies in healthy volunteers and patients with gastroesophageal reflux disease, including erosive esophagitis, from Asia and Europe. This model was used to evaluate the impact of different covariates, including race and disease status, on vonoprazan exposure. We analyzed PK data from 746 patients and 410 healthy volunteers from 15 clinical trials using a nonlinear mixed-effects approach to develop the popPK model. Model development focused on characterizing and quantifying the effects of clinical covariates of race (Asian vs non-Asian) and disease status (gastroesophageal reflux disease vs healthy volunteers) on vonoprazan exposure. Identified clinical covariates included fed/fasting status, race, sex, disease status, weight, serum creatinine, and age. The impact of variations in these clinical covariates on exposure to vonoprazan was smaller than the effect of halving or doubling the dose. PK parameters were similar in Asian and non-Asian populations. Variations in weight, age, and race are not predicted to have a clinically relevant impact on vonoprazan exposure or safety and require no changes in vonoprazan dosing. The limited impact of race on exposure suggests that efficacy and safety data for vonoprazan in Asian populations are translatable to non-Asian populations., (© 2021 The Authors.

Introduction: Oesophageal candidiasis is a common infection among individuals with immunosuppression, associated with significant morbidity. Available guidelines recommend fluconazole as the preferred treatment; however, data regarding its effectiveness in an era of increased fluconazole resistance has not been systematically compiled., Methods: A systematic review and meta-analysis of randomized controlled trials (RCTs) addressing systemic antifungal therapy for oesophageal candidiasis was undertaken. The primary outcome was clinical response. Subgroup analysis was planned based on immune status and Candida spp., Results: Twelve RCTs were included, of which six compared fluconazole with other azoles, four compared fluconazole with echinocandins, and two compared amphotericin deoxycholate with echinocandins. Most RCTs mainly included human-immunodeficiency-virus-positive individuals. No significant differences were found between fluconazole and comparators for the outcomes of clinical response or combined clinical and endoscopic response [relative risk (RR) 1.02, 95% confidence interval (CI) 0.97-1.07 and RR 1.06, 95% CI 0.98-1.15, respectively]. No differences were found between fluconazole and other azoles for other outcomes; however, compared with echinocandins, fluconazole had significantly higher mycological response rates and lower early relapse rates (RR 1.09, 95% CI 1.02-1.17 and RR 0.42, 95% CI 0.26-0.68, respectively). No significant differences were demonstrated between fluconazole and comparators for overall or severe adverse events. Information required for the planned subgroup analyses was not available., Conclusions: No differences in efficacy or safety were found between fluconazole and other azoles for the treatment of candida oesophagitis. The use of echinocandins resulted in lower mycological cure rates and higher relapse rates. Additional RCTs should evaluate these interventions among broader patient populations and a wider spectrum of Candida spp., (Copyright © 2022 Elsevier Ltd and International Society of Antimicrobial Chemotherapy.

Background: Keverprazan is a novel potassium-competitive acid blocker (P-CAB) with a strong acid-suppressive capacity that may provide clinical benefit in acid-related diseases., Aims: This study aimed to explore the non-inferior efficacy and safety of keverprazan to lansoprazole in treating erosive oesophagitis (EO)., Methods: This was a phase III, randomised, double-blind multicentre study. Patients were randomised to receive keverprazan 20 mg once daily or lansoprazole 30 mg once daily for 4-8 weeks. EO healing rates and adverse events (AEs) were compared between the keverprazan group and the lansoprazole group., Results: A total of 238 patients comprised the full analysis set (FAS) while 221 patients comprised the per-protocol set (PPS). For FAS analysis, the EO healing rates at week 8 were 95.8% (114/119) and 89.9% (107/119) for keverprazan and lansoprazole respectively. For PPS analysis, the EO healing rates at week 8 were 99.1% (110/111) and 92.7% (102/110) for keverprazan and lansoprazole respectively. Non-inferiority of keverprazan compared with lansoprazole according to EO healing rates at 8 weeks was demonstrated in both FAS (difference: 5.8% [95% CI: -0.6% to 12.3%]; p = 0.081) and PPS (difference: 6.1% [95% CI: 1.1%-11.2%]; p = 0.018) analysis. Drug-related AEs were reported in 34.5% (41/119) patients of the keverprazan group and 25.2% (30/119) patients of the lansoprazole group with no significant difference (p = 0.156). No severe AE happened in the keverprazan group., Conclusions: This study demonstrated the non-inferior efficacy of keverprazan to lansoprazole in treating EO. The incidences of drug-related AEs were comparable between keverprazan and lansoprazole., (© 2022 John Wiley & Sons Ltd.)

Background: Esophagitis is prevalent in patients with esophageal dysmotility despite acid suppression, likely related to poor esophageal clearance. Esophageal atresia (EA) is a classic model of dysmotility where this observation holds true. In adult non-dysmotility populations, failure of esophagitis to respond to proton pump inhibitors (PPI) has been linked to variants in CYP2C19 that influence the activity of the encoded enzyme. It is unknown if CYP2C19 metabolizer phenotype contributes to PPI-refractory, non-allergic esophagitis in EA., Methods: We performed a cross-sectional study of 314 children with (N = 188) and without (N = 126) EA who were on PPI therapy at the time of endoscopy to evaluate for possible gastroesophageal reflux disease. Patients with eosinophilic esophagitis and/or fundoplication were excluded. Clinical and histology data were collected. Genomic DNA from biopsy samples was genotyped for polymorphisms in CYP2C19., Results: CYP2C19 metabolizer phenotypes were not associated with presence or severity of esophagitis (P = 0.994). In a multivariate logistic regression adjusted for potential confounders, EA was the strongest and only significant predictor of esophagitis (odds ratio 2.72, P = 0.023). Using negative binomial regression, we found that CYP2C19 phenotype was not a significant predictor of eosinophil count in children with PPI-refractory esophagitis., Conclusions: Patients with EA are significantly more likely to experience PPI-refractory, non-allergic esophagitis than controls regardless of CYP2C19 metabolizer phenotype, suggesting that factors other than CYP2C19 genetics, including dysmotility, are the primary drivers of esophagitis in EA. CYP2C19 genotype failed to predict PPI-refractory, non-allergic esophagitis in both EA and non-EA children., (© 2021 John Wiley & Sons Ltd.)

Herpes simplex virus-1 (HSV-1) oesophagitis as an aetiology of persistent hiccough is a rarity in immunocompetent hosts and entails an exhaustive diagnostic work-up, since it does not present with any of the typical oesophagitis symptoms. Our patient presented with persistent hiccoughs that were resistant to treatment with baclofen. Oesophagogastroduodenoscopy with biopsy confirmed the diagnosis of HSV-1 oesophagitis. The hiccough subsided within 48 h of aciclovir therapy.

A 77-year-old woman presented with a 2-week history of malaise, prostration, anorexia, abdominal pain, vomiting and diarrhoea. She had been taking systemic corticosteroids for the past year. During hospitalisation, renal insufficiency, ionic changes and liver function abnormalities were detected and corrected. However, the patient developed total dysphagia. UGE revealed multiple shallow ulcers below the cricopharyngeal level and in the distal oesophagus, with normal-appearing intervening mucosa. Histological examination allowed the diagnosis of herpes simplex virus esophagitis. Treatment with intravenous acyclovir was instituted for 14 days. In the elderly, herpetic esophagitis may present with non-specific complains, such as prostration or anorexia. In the reported case, dysphagia was only detected as a late symptom, addressing the importance of maintaining a high degree of suspicion for the diagnosis of herpes simplex virus esophagitis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

There is limited evidence to support pharmacogenetic (PGx) testing in children. We conducted a retrospective review of PGx testing among 452 patients at an academic children's hospital to determine the potential utility of PGx in diseases of childhood and to identify targets for future pediatric pharmacogenetic research. An actionable gene-drug pair associated with the 28 genes tested (Clinical Pharmacogenetics Implementation Consortium (CPIC) level A or B, Pharmacogenomics Knowledge Base (PharmGKB) level 1A or B, or US Food and Drug Administration (FDA) recommendation and a PharmGKB level) was present in 98.7% of patients. We identified 203 actionable gene-drug-diagnosis groups based on the indications for each actionable drug listed in Lexicomp. Among patients with an actionable gene-drug-diagnosis group, 49.3% had a diagnosis where the drug was a therapeutic option and PGx could be used to guide treatment selection. Among patients with an associated diagnosis, 30.9% had a prescription for the actionable drug allowing PGx guided dosing. Three genes (CYP2C19, CYP2D6, and CYP3A5) accounted for all the gene-drug-diagnosis groups with matching diagnoses and prescriptions. The most common gene-drug-diagnosis groups with matching diagnoses and prescriptions were CYP2C19-citalopram-escitalopram-depression 3.3% of patients tested; CYP2C19-dexlansoprazole-gastritis-esophagitis 3.1%; CYP2C19-omeprazole-gastritis-esophagitis 2.4%; CYP2D6-atomoxetine-attention deficit hyperactivity disorder 2.2%; and CYP2C19-citalopram-escitalopram-obsessive-compulsive disorder 1.5%. PGx could be used to guide selection of current treatment options or medication dosing in almost half (48.7%) of pediatric patients tested. Mood disorders and gastritis/esophagitis are promising targets for future study of PGx testing because of the high prevalence of these diagnoses and associated actionable gene-drug pairs in the pediatric population., (© 2020 The Authors.

Introduction: Indefinite proton pump inhibitor (PPI) therapy and endoscopic evaluation for Barrett's esophagus is recommended for erosive esophagitis (EE). However, the clinical course of EE remains undefined., Methods: Adults with EE on esophagogastroduodenoscopy (EGD) were identified at Mayo Clinic Rochester between January 2003 and September 2005. Patients with repeat EGD performed after index endoscopy were included. Patients with a history of upper gastrointestinal surgery, esophageal cancer, achalasia, or Barrett's on initial EGD were excluded., Results: Of 219 patients identified, 98 had LA grade A, 72 LA grade B, and 49 LA grade C esophagitis. Persistent EE was found in 27% on repeat endoscopy. No patients progressed to more severe grades of esophagitis. While discontinuation of PPI was associated with persistent esophagitis, long-term healing of esophagitis occurred in the majority of patients despite discontinuation of PPI. Grade A or B esophagitis and the absence of hiatal hernia were also independent predictors of esophagitis healing on multivariate analysis. The rate of Barrett's esophagus was similar among patients with LA grade A/B and C esophagitis on initial EGD (5% vs. 14%, p = 0.6)., Conclusion: The majority of patients with EE demonstrated healing at follow-up endoscopy regardless of continued PPI use. A small proportion developed Barrett's esophagus, including those with LA grade A and B esophagitis, highlighting a potential role for repeat endoscopy in all grades of EE. A more conservative long-term PPI strategy may be reasonable in patients with LA grade A or B esophagitis in the absence of hiatal hernia.

Background/aim: Proton pump inhibitor (PPI) alone is not satisfactory for the treatment of gastroesophageal reflux disease (GERD). Therefore, we investigated the efficacy of DA-5204 (Stillen 2X, 90 mg of Artemisia asiatica 95% ethanol extract per tablet) and PPI combination therapy on GERD in comparison to PPI alone., Methods: This randomized, double-blind, placebo-controlled study randomly assigned 70 patients with endoscopically proven esophageal mucosal injury (Los Angeles classification grade A or B) into 2 groups: pantoprazole 40 mg once daily with DA-5204 twice daily (DA-5204 group) or pantoprazole 40 mg once daily with placebo twice daily (placebo group) for 4 weeks. The primary endpoint was endoscopic healing rate. The secondary endpoint was sufficient relief (≥50% reduction) of symptoms using GERD Questionnaire., Results: Final analyses included 29 patients with the DA-5204 group and 30 patients with the placebo group. At weeks 4, there was no significant difference in the endoscopic healing rate between the 2 groups (DA-5204 vs placebo; 96.6% vs 93.3%; P = 1.000). However, the rate of residual minimal change was significantly lower in the DA-5204 group (5/28, 17.9%) than in the placebo group (17/28, 60.7%) (P < .001). The rates of symptom relief were not different between the DA-5204 group and the placebo group (all P > .05)., Conclusion: Combined therapy with PPI and DA-5204 has no additional effect on the endoscopic healing rate compared to PPI alone. However, it may be beneficial in resolving minimal change.

Background: Herpes esophagitis is uncommon disease caused by Herpes simplex virus (HSV). While the disease most often occurs in immunocompromised patients, including post-chemotherapy, immunosuppression with organ transplants, and in AIDS, Herpes esophagitis can also occur in immunocompetent individuals., Case Presentation: We report a case of herpes esophagitis in a 72 year- old woman who was presumed to be immunocompromised following prolonged radiotherapy and chemotherapy for lymphoma. Her main symptom was epigastric pain. Upper endoscopy showed multiple rounded ulcers in lower esophagus. The diagnosis was confirmed histologically by multiple biopsies. The patient received Valacyclovir for 2 weeks and started to get better within 3 days of treatment., Conclusion: Although there are few published cases of Herpes esophagitis disease in the medical literature, we recommend that this disease should be considered as one of the differential diagnoses when assessing immuno-compromised patients presenting with non-specific abdominal symptoms.
