Generalized pustular psoriasis is a rare variant of psoriasis. Evidence recommending generalized pustular psoriasis treatment with secukinumab is limited. This report aims to evaluate the use of secukinumab in two patients with generalized pustular psoriasis. The standard treatment regimen for secukinumab was as follows: 300mg subcutaneously once weekly in weeks 0-4, followed by 300mg every four weeks. The efficacy was evaluated by analyzing the psoriasis area and severity index (PASI) and dermatology life quality index (DLQI). One patient had generalized pustular psoriasis, which had developed from palmoplantar pustulosis over 12 years. The second patient was an adolescent with recurrent generalized pustular psoriasis. The first patient achieved PASI-75 response by week 3 and both PASI-90 and a DLQI score of 0 were observed by week 8. The second patient achieved PASI-75 response by week 4 and complete clinical resolution, except for nail changes, and a DLQI of 0 by week 8, without any adverse events.

Secukinumab is a fully human IgG1 antibody that selectively binds to and neutralizes the proinflammatory cytokine interleukin-17A. Secukinumab is an effective and well-tolerated treatment for plaque psoriasis. There is a limited real-word evidence for dose optimisation of secukinumab based on clinical response. PURE is a multi-national, prospective, observational study in patients with moderate to severe chronic plaque psoriasis in Canada and Latin America, assessing the real-world safety and effectiveness of secukinumab and other indicated therapies. The aim of the current snapshot analysis was to evaluate the effectiveness and safety of on-label dose and updosed secukinumab in patients with plaque psoriasis enrolled in the PURE study. At the time of analysis, 676 patients received secukinumab, of which 84.6% (n = 572) remained on the on-label dose, while 15.4% (n = 104) were updosed. With on-label secukinumab, the absolute Psoriasis Area and Severity Index (PASI) score was reduced from 13.6 at baseline to 1.2 over 36 months, with treatment persistence of 73% at 40 months. At Month 36, 73.2% of the patients receiving on-label secukinumab achieved Investigator's Global Assessment (IGA) 0/1. With updosed secukinumab (300 mg every 2 weeks, 300 mg every 3 weeks, 450 mg every 4 weeks, or 450 mg every 3 weeks), 57.9% of the patients showed improvement in the absolute PASI score at the first visit after updosing, with treatment persistence of 50% at 12 months after updosing. At Month 15, 40% of patients receiving updosed secukinumab achieved IGA 0/1. Patients with previous biologic exposure (odds ratio [OR]: 3.25; 95% confidence interval [CI]: 2.03, 5.18, p < 0.0001) were more likely to be updosed while those with a body weight < 90 kg (OR: 0.49; 95% CI [0.31, 0.77], p = 0.0019) were less likely to be updosed. Previous biologic exposure (HR [hazard ratio]: 1.47; 95% CI [1.24, 1.75], p < 0.0001) and current biologic exposure (secukinumab vs. other indicated therapies: HR 0.57; 95% CI [0.43, 0.75], p = 0.0001) were significantly associated with time to secukinumab updosing. No new or unexpected safety signals were observed with updosed secukinumab. Secukinumab updosing was efficacious and well-tolerated in patients with psoriasis who failed to respond to the approved on-label regimen, suggesting that updosing may be a useful therapeutic option for approved dose non-responders.

Introduction: A previous network meta-analysis established 16-week relative efficacy with bimekizumab, an inhibitor of interleukin (IL)-17F in addition to IL-17A, versus other treatments for patients with radiographic axial spondyloarthritis (r-axSpA; i.e., ankylosing spondylitis), including the IL-17A inhibitors secukinumab and ixekizumab. This matching-adjusted indirect comparison (MAIC) assessed 52-week relative efficacy of bimekizumab versus secukinumab and ixekizumab. Methods: Individual patient data from BE MOBILE 2 (bimekizumab 160 mg; N = 220) were matched to pooled summary data from MEASURE 1/2/3/4 (secukinumab 150 mg), MEASURE 3 (secukinumab 300 mg; escalated dose for inadequate responders), COAST-V (ixekizumab) and COAST-V/-W (ixekizumab). BE MOBILE 2 patients were reweighted using propensity score weights based on age, sex, ethnicity, tumor necrosis factor inhibitor (TNFi) exposure, weight, baseline ASDAS and BASFI (secukinumab) and baseline BASDAI (ixekizumab), and 52-week efficacy outcomes from the trial recalculated. Odds ratios (OR) or mean difference for unanchored comparisons are reported with 95% confidence intervals (CI). Results: At week 52, MAIC demonstrated that patients may have higher likelihood of improvement in key efficacy outcomes with bimekizumab versus secukinumab 150 mg (e.g., ASAS40: [OR (95% CI): 1.48 (1.05, 2.10); p = 0.026]; effective sample size [ESS] = 177). Differences in 52-week efficacy outcomes between bimekizumab and secukinumab 300 mg dose escalation were non-significant (ESS = 120). Bimekizumab versus ixekizumab 80 mg comparisons (COAST-V only; ESS = 84) also suggested that differences were non-significant for most key efficacy outcomes. Other ixekizumab comparisons (COAST-V/-W; ESS = 45) suggested bimekizumab may have higher comparative efficacy for many of the same efficacy outcomes, however ixekizumab analyses were limited by poor population overlap, likely due to the greater proportion of patients with previous TNFi exposure. Conclusions: Patients treated with bimekizumab may have a higher likelihood of achieving improved longer-term efficacy versus secukinumab 150 mg, suggesting bimekizumab may be a favorable therapeutic option for r-axSpA. Differences in efficacy outcomes with bimekizumab versus ixekizumab 80 mg were mostly non-significant, depending on the populations considered. [ABSTRACT FROM AUTHOR]

Vitiligo is a chronic depigmenting disorder that significantly impacts the quality of life of patients. Though there have been significant advancements in targeted therapies in skin diseases such as psoriasis or eczema, the progress in the treatment of vitiligo has been slow, with minimal studies assessing the effect of biologics, though there has been recent evidence of the effectiveness of JAK inhibition. This paper reviews the published case reports and studies for the use of systemic targeted therapies including biologics and JAK inhibitors in vitiligo. [ABSTRACT FROM AUTHOR]

Introduction: Despite the availability of several treatments for psoriasis (PsO), factors influencing the persistence of secukinumab (SEC) therapy remain inadequately understood. This study aimed to identify predictors of SEC persistence in PsO. Methods: A retrospective analysis was conducted on 109 PsO patients who received SEC treatment at least 1 year. Patients were categorized based on continued or discontinued SEC therapy. Results: Among the 109 patients, 64 continued SEC treatment while 45 discontinued. Univariate analysis demonstrated that PsA presence and previous biologic therapy use increased the risk of SEC discontinuation 3.56- and 2.33-fold (p = 0.001, %95 CI: 1.66–7.65 and p = 0.032, %95 CI: 1.08–5.04, respectively). Additionally, the risk of SEC discontinuation is 57% higher in patients with a body mass index (BMI) above 26.5 compared to those with a BMI below 26.5 (p = 0.016, %95 CI: 0.22–0.85). Additionally, patients with PsO onset age below 26.5 years were found to have a 2.93-times higher risk of discontinuing SEC compared to those with PsO onset age above 26.5 years (p = 0.004, %95 CI: 1.40–6.13). Conclusion: PsA presence, previous biologic therapy experience, BMI, and PsO onset age were identified as independent predictors of SEC discontinuation. These findings underscore the importance of personalized treatment strategies for PsO patients receiving SEC therapy. [ABSTRACT FROM AUTHOR]

The etiology of Guillain-Barre' syndrome (GBS) may be autoimmune. About twothirds of patients typically experience their first symptoms within 5 days to 3 weeks after common infectious diseases, surgery, or vaccination. Infection is a triggering factor for over 50% of patients. In recent years, a growing number of studies have indicated that some immune checkpoint inhibitors and COVID-19 may also contribute to the occurrence of GBS. However, drugs are considered a rare cause of GBS. The patient in our case was a 70-year-old man who developed GBS after initiating secukinumab for psoriasis. Upon diagnosis suggesting a potential association between secukinumab and the development of GBS, as per the Naranjo adverse drug reaction (ADR) probability scale, we decided to discontinue the drug. Following this intervention, along with the administration of immunoglobulin, the patient exhibited a significant improvement in extremity weakness. The association of GBS with secukinumab treatment, as observed in this case, appears to be uncommon. The underlying mechanisms that may link secukinumab to the development of GBS are not yet fully understood and warrant further scientific inquiry and rigorous investigation. However, we hope that this report can raise greater awareness and vigilance among medical professionals to enhance the safety of patients' medication. [ABSTRACT FROM AUTHOR]

Introduction: the selective IL-17 inhibitor secukinumab has demonstrated efficacy and safety in the treatment of moderate–severe psoriasis in recent years. Objective: evaluate effectiveness and drug survival (DS) of secukinumab in patients with psoriasis for up to 5 years. Methods: This is a retrospective study on a monocentric cohort of patients with psoriasis on secukinumab evaluating the achievement of PASI100, PASI90, and PASI ≤ 3 and DS analysis up to 260 weeks. DS multivariate analysis was carried out considering sex, age, age of onset of the disease, obesity, cardiovascular comorbidities, diabetes, involvement of difficult-to-treat sites, psoriatic arthritis, treatment-naïve status, and mean baseline PASI. Results: At baseline, we evaluated 255 patients on secukinumab. PASI100 was reached by 41.7% and 70.6% of patients at weeks 16 and 260, respectively. PASI90 showed a similar trend with 46.5% of patients achieving it at week 16 and 88.2% at week 260. Non-obese patients showed a faster response than patients with obesity in achieving PASI100, PASI90, and PASI ≤ 3, with significant differences at 28 weeks [55% vs. 40% (p = 0.033), 64% vs. 49% (p = 0.038), and 76% vs. 62% (p = 0.036), respectively]. The estimated DS for secukinumab was 84.3% at 12 and 48% at 60 months. Obesity and smoking habits were associated with a higher risk of discontinuation in multivariate models (HR 1.6 CI 1.05–2.45, p = 0.028; HR 1.48 CI 1.01–2.17, p = 0.043, respectively). Conclusions: Secukinumab showed effectiveness for up to 5 years of treatment, with a high DS and achievement of PASI100, PASI90, and PASI < 3 at these time points. Only obesity reduced the response and maintenance of DS. [ABSTRACT FROM AUTHOR]

Introducion: The concept of a window of opportunity in hidradenitis suppurativa (HS) management suggests that early initiation of biological therapy leads to better outcomes, though its timing remains uncertain. Methods: We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55). Additionally, potential predictors of response to secukinumab were studied. Analysis was performed on an intention-to-treat basis. Results: A total of 67 patients (33 men, 34 women) were included, with a mean age of 41.55 (11.94) years and a mean baseline IHS4 of 17.88 (11.13). The mean therapeutic burden was 6.06 (3.49). At week 24, 10.45% (7/67) of patients experienced adverse events, with three leading to treatment discontinuation. At week 24, 41.79% (28/67) of patients achieved HiSCR, and 44.78% (30/67) of patients achieved IHS4-55. HiSCR could not be calculated in 12 patients with a baseline AN count < 3. A lower therapeutic burden was significantly associated with a higher likelihood of achieving HiSCR and IHS4-55 at week 24. Conclusions: Secukinumab showed safety and efficacy in real-world patients with HS, and the inverse correlation found between therapeutic burden and treatment response supports the concept of a window of opportunity, offering insights into its timing.

Real‐world data on the long‐term effectiveness of the anti‐IL17 agent secukinumab in treating moderate‐to‐severe Hidradenitis suppurativa (HS) are lacking. In this study, 24 patients with moderate–severe HS received five weekly subcutaneous injections followed by maintenance doses every 4 weeks. Primary outcomes included HiSCR, IHS4 reduction, and DLQI measures assessed at 12‐week intervals. The median secukinumab drug survival was 16.0 months (range 3–51), with a 56.5% maximal response rate at 6 months and dropout exceeding 40% at 1 year. Baseline disease burden emerged as a key predictor of treatment response, overshadowing factors like sex or BMI. Prior systemic steroid use negatively impacts drug survival. The study underscores the critical 6‐month window for assessing treatment efficacy, emphasizing the importance of initial induction dosing. Additionally, the newly developed scoring system, IHS4‐55, showed analogies to the older HiSCR score in capturing treatment response. In this real‐life scenario, challenges persist in HS management, necessitating innovative therapeutic approaches and predictive markers. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusion In comparison with TNF‐α inhibitors, anti‐IL‐17A agents are considered to have a lower risk of active tuberculosis (TB) or latent TB infection (LTBI) reactivation.In this study, we aimed to evaluate the TB infection status and serial QuantiFERON‐TB‐Gold in tube test (QFT) results of psoriasis patients using IL‐17 inhibitors (secukinumab [SEC] and ixekizumab [IXE]) in a real‐world setting from a tuberculosis‐endemic country. Patients who used an anti‐IL‐17 agent for at least 3 months in our follow‐up were included in the study. Patients' clinical and demographic features, baseline QFT results and latest QFT results (if any), and TB infection status were noted from the past medical records.A total of 717 patients, of whom 333 (46.4%) were female, were included in the study. The cumulative exposure time to an anti‐IL‐17 agent was 14,147 patient‐months, 9743 patient‐months for SEC and 4404 patient‐months for IXE. Also, 459 (SEC = 305/IXE = 154) patients used an anti‐IL‐17 agent for ≥ 12 months. Of these, 125 had positive baseline QFT results. In all, 334 had negative baseline QFT results. The latest QFT result of 309 was also negative (persistent seronegative group). During follow‐up, the QFT results of 10 patients changed from negative to positive (positive seroconversion group). Seven of them were using SEC and three were using IXE, respectively. No case of active TB infection was detected.In our study, the positive seroconversion rate of 10/334 seems high, but this did not translate to active disease. However, closer monitoring may be required, especially in patients with advanced age, the presence of PsA, long disease duration and long anti‐IL‐17 treatment duration. [ABSTRACT FROM AUTHOR]

Rationale: Relapsing polychondritis (RP) is an immune-mediated systemic inflammatory disease involving cartilage and proteoglycan-rich tissues. Pustular psoriasis (PP) is a psoriasis subtype characterized by skin erythema and sterile pustules. In previous studies, there were few reports on patients with RP combined with psoriasis, and treatment strategies are not standardized. Patient concerns: An 80-year-old Chinese woman with a 7-year history of atrial fibrillation, a 1-year history of coronary atherosclerotic heart disease, and no familial history, had a 2-month history of skin rash, erythema, swelling and pain in both hands, swollen bilateral auricles, and fingertip gangrene. Diagnosis: Based on the diagnostic criteria for generalized pustular psoriasis proposed by Fujita et al. in 2018 and RP proposed by McAdam et al. in 1975, we diagnosed RP with PP as the predominant manifestation. Interventions: We started therapy with subcutaneous secukinumab 150 mg weekly for the first month, then 150 mg monthly thereafter. Outcomes: After 2 weeks of secukinumab administration, the patient showed significant remission of pustular skin lesions, with almost no joint pain, swollen bilateral auricles, and no adverse reaction. Conclusions: Pustular lesions secondary to RP-associated gangrene and swollen auricles were observed, demonstrating a potential immune correlation between RP and psoriasis in some patients. Although data related to the use of secukinumab for RP and PP is very limited due to the rarity of the two conditions presented together, secukinumab provides a novel therapeutic option. Further prospective studies are needed to support our findings. [ABSTRACT FROM AUTHOR]

This study investigates the combined treatment of secukinumab (SECU) and magnolol (MAGN) in a mouse model of LPS-induced ALI overlapped with allergic pulmonary inflammation, aiming to better understand the mechanism behind this pathology and to assess the therapeutic potential of this novel approach in addressing the severity of ALI. The combined treatment reveals intricate immunomodulatory effects. Both treatments inhibit IL-17 and promote M2 macrophage polarization, which enhances anti-inflammatory cytokine production such as IL-4, IL-5, IL-10, and IL-13, crucial for lung repair and inflammation resolution. However, the combination treatment exacerbates allergic responses and increases OVA-specific IgE, potentially worsening ALI outcomes. MAGN pretreatment alone demonstrates higher potency in reducing neutrophils and enhancing IFN-γ, suggesting its potential in mitigating severe asthma symptoms and modulating immune responses. The study highlights the need for careful consideration in therapeutic applications due to the combination treatment's inability to reduce IL-6 and its potential to exacerbate allergic inflammation. Elevated IL-6 levels correlate with worsened oxygenation and increased mortality in ALI patients, underscoring its critical role in disease severity. These findings offer valuable insights for the advancement of precision medicine within the realm of respiratory illnesses, emphasizing the importance of tailored therapeutic strategies.

Abstract Hidradenitis suppurativa is a chronic inflammatory disease of the hair follicle that affects the axillary and gluteal regions. Hidradenitis can coincide with other inflammatory diseases, such as ankylosing spondylitis. We present a patient suffering from an overlap of both conditions, who had a rapid improvement with secukinumab.

Background: Erythrodermic psoriasis (EP) is a potentially life-threatening disease, and there is currently no consensus regarding its optimal treatment. Biological drugs approved for Psoriasis Vulgaris treatment have been used as alternatives to traditional medications. Objective: To evaluate the clinical response and tolerability of anti- interleukin 17 (IL17) biologic drugs during a 2-year-follow-up. Methods: This was a retrospective prospective study. EP cases, defined as >75% body surface area involvement, in patients ≥18 years old treated with anti-IL17 for at least 6 consecutive months were enrolled and then followed until 104 weeks. Patient characteristics, overall clinical responses, Psoriasis Area Severity Index score changes, and adverse events were analyzed. Results: Sixteen patients met the criteria, of which 50% had achieved the Psoriasis Area Severity Index 100 response at week 12 and in 93.7% at week 24. In the prospective observation of the cohort, 87.5% were still in remission at week 52 and 81.25% at 104 weeks, without adverse events. The 3 patients in whom the treatment was interrupted lost efficacy and were switched to other therapies. Limitations: Only descriptive analysis was conducted due to the limited number of patients. Conclusions: A satisfactory long-term clinical response without adverse effects was observed in this case series, suggesting the interest of anti-IL17 in EP treatment.

This study compared the pharmacokinetics (PK), safety, and immunogenicity of CMAB015, a candidate secukinumab biosimilar, with the reference product secukinumab (Cosentyx®) in healthy Chinese male subjects.Patients and methods: This double-blind, parallel-group study randomized healthy Chinese male subjects (N=130) to receive either a single dose of 150 mg CMAB015 or secukinumab subcutaneously. Primary study endpoints were PK parameters such as the maximum concentration (Cmax) and area under the curve from zero to infinity (AUC0-inf), while safety and immunogenicity were secondary endpoints.Results: The 90% confidence intervals (CIs) of the geometric mean ratios (GMRs) of Cmax and AUC0-inf for CMAB015 to secukinumab were all within the bioequivalence limits (80.00– 125.00%). Other PK parameters were comparable between the groups. The safety profile of CMAB015 was similar to that of secukinumab, with no serious adverse events related to treatment. The incidence of TEAEs was slightly higher in the CMAB015 group, but these events were mild to moderate in severity and did not lead to any withdrawals from the study. Immunogenicity analysis revealed low rates of anti-drug antibody (ADA) positivity, with similar rates between CMAB015 and secukinumab.Conclusion: This study demonstrated equivalent PK, comparable safety, and immunogenicity of CMAB015 to secukinumab in healthy Chinese male subjects. These findings support further clinical evaluation of CMAB015 as a secukinumab biosimilar.Trial Registration: The trial was registered on Clinicaltrials.gov (Identifier No. NCT05734482) and Chinadrugtrials.org.cn (Identifier No. CTR20230105).Keywords: CMAB015, secukinumab, biosimilar, pharmacokinetics, safety, immunogenicity

Although there have been many reports of biological agents treating pityriasis rubra pilaris recently, the clinical application of the JAK inhibitors in the treatment of pityriasis rubra pilaris has been rarely reported, and there is a lack of evidence on the safety and efficacy of these drugs. We explore the use of the JAK inhibitor tofacitinib in the treatment of pityriasis rubra pilaris with significant efficacy and no significant side effects, providing new ideas for the clinical treatment of pityriasis rubra pilaris.Methods: We cover a case of pityriasis rubra pilaris treated with the JAK inhibitor tofacitinib, which showed significant efficacy without any adverse effects.Results: This case report showed that the JAK inhibitor tofacitinib had significant clinical efficacy in the treatment of pityriasis rubra pilaris. We speculated that the treatment of pityriasis rubra pilaris with the JAK inhibitors may be related to blocking the activation of the JAK/STAT pathway, thereby blocking the high expression of cytokines IL-17, IL-12/IL-23, IL-23, TNF-α.Conclusion: The JAK inhibitor tofacitinib can become a new option for treating pityriasis rubra pilaris.Keywords: pityriasis rubra pilaris, JAK inhibitors, tofacitinib, secukinumab, ustekinumab

The objective of this retrospective cohort study was to assess the relationship between corona Disease 2019 (COVID-19) and secukinumab treatment in patients with spondylarthritis (SpA) in china during the omicron surge. Researchers retrieved 1018 medical records of secukinumab-treated patients between January 2020 and January 2023 from the West china hospital of sichuan University. Out of these, 190 spa patients from the rheumatology clinic were selected for the study. Guided phone questionnaires were administered by research staff to collect baseline characteristics, spa disease status, and COVID-19 clinical outcomes. Cohabitants served as the control group and provided COVID-19 related data. Of the 190 potential spa patients, 122 (66%) completed the questionnaire via phone, along with 259 cohabitants. 84.4% of spa patients were diagnosed with ankylosing spondylitis (AS), and 15.6% were diagnosed with Psoriatic arthritis (PsA). the rate of SARS-COV-2 infection was 83.6% in the secukinumab group and 88.8% in the cohabitants control group, with no significant difference (OR = 0.684, CI 0.366-1.275). One instance of severe COVID-19 was observed in the secukinumab group, while two were identified in the cohabitants control group. Patients in the secukinumab group had less time with fever caused by COVID-19 (p = 0.004). Discontinuing secukinumab after SARS-COV-2 infection did not significantly affect the course of COVID-19 or worsen spa status according to our data. Our study suggests that administering secukinumab to spa patients does not increase their susceptibility to contracting SARS-CoV-2, and may have a positive effect on the course of SARS-COV-2 infection.

In recent years Janus kinase inhibitors (JAKi) have joined tumor necrosis factor inhibitors (TNFi) and interleukin (IL)-17 inhibitors (IL-17i) as approved disease modifying anti-rheumatic drugs (DMARD) for moderate to severe forms of axial spondyloarthritis (axSpA). Drug survival in axSpA patients has not been well studied in a real-world outpatient scenario since the approval of JAKi. We aimed to analyze the three drug classes based on modes of actions (MoA) for their persistence rates among German axSpA outpatients. A retrospective analysis of the RHADAR database for axSpA patients with a new initiation of TNFi, IL-17i, or JAKi treatment between January 2015 and October 2023 was conducted. Analyses included Kaplan-Meier curves and adjusted Cox regressions for drug discontinuation. 1222 new biological DMARD (TNFi [n = 954], IL-17i [n = 190]) or JAKi (n = 78) treatments were reported. The median drug survival was 31 months for TNFi, 25 for IL-17i, and 18 for JAKi. The corresponding 2-year drug survival rate was 79.6%, 72.6%, and 62.8% for TNFi, IL-17i, and JAKi, respectively. The probability for discontinuation for JAKi was significantly higher compared with TNFi (HR 1.91 [95% CI 1.22–2.99]) as well as for IL-17i compared with TNFi (HR 1.43 [95% CI 1.02–2.01]), possibly related to more frequent use of TNFis as first-line therapy. IL-17i and JAKi discontinuation probabilities were similar. Primary non-response was the reason for drug discontinuation in most cases across all MoA. TNFi treatment might persist longer than JAKi and IL-17i in German axSpA outpatients, possibly related to more severe or refractory disease in patients with JAKi-treated or IL-17i-treated axSpA.

Methods We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55).

Increased understanding of its pathophysiology has enabled development of targeted treatments such as biologics. Several medical treatments have been shown to be influenced by patients’ experiences and expectations. However, only little is known about patients’ experiences with and expectations towards biologics. Our objectives were to identify patients’ treatment experiences and treatment expectations and assess their trajectories over the course of treatment with the IL-17A inhibitor secukinumab. Moreover, we aimed to document effects of psoriasis, factors that influence symptomatology, and prior treatment experiences.Patients and Methods: We conducted semi-structured interviews with n = 24 patients with moderate-to-severe plaque psoriasis and employed a qualitative content analysis to derive thematic and evaluative codes. Findings were validated via peer debriefings with experienced dermatologists.Results: Patients reported burdensome physical and psychological psoriasis symptoms and identified factors that can improve or worsen symptomatology, including stress and self-efficacy. Prior treatment experiences were mostly negative. Past barriers to effective treatment included time constraints or limited access. Concerning secukinumab, patients initially expected complete to partial remission of symptoms and occurrence or absence of side effects. Closer inspection of expectations and experiences revealed three trajectories. For most patients, initial expectations were met and future expectations remained unchanged. For the other patients, however, the experience did not match their initial expectation. One group then adapted their future expectations according to their experience, while the other group did not.Conclusion: To our knowledge, this is the first qualitative study to assess expectations towards treatment effectiveness and side effects, their trajectories, and interplay with experiences among psoriasis patients. Our findings highlight the value of further research on the subject in order to optimize care for psoriasis patients and to learn more about the trajectories and influence of treatment expectations in general.Plain Language Summary: Patients’ expectations towards a certain treatment can influence how well it will work and whether side effects occur or not. Such effects have been shown for a wide range of conditions, including dermatological ones. For patients suffering from psoriasis, a chronic inflammatory skin disease, modern biologics offer promising treatment options. Therefore, modern biologics are likely associated with high expectations by patients. Yet, the roles of treatment expectations and the experiences of patients undergoing biologic treatment have only received little attention to date.With this qualitative study, we aimed to understand patients’ perspectives on these treatments, the symptoms they suffer from, expectations towards treatment effectiveness and side effects as well as treatment experiences in the past and over the course of treatment with a modern biologic. To this end, we conducted and transcribed interviews with 24 patients after several months of biologic treatment. We then analyzed interview transcripts to determine underlying categories and summarized these in a common framework.We found that patients’ debilitating physical and psychological symptoms were often not well controlled in past treatments. Still, patients had positive expectations with regard to biologic treatment. For a large group of patients, their actual experiences met their expectations, leaving them with unchanged expectations for the future. Another important finding was the good understanding of factors influencing their symptomatology that patients had, like stress and self-efficacy. The reported findings may aid doctors in their clinical work, to further improve care for psoriasis patients.

Subsequently, the patient developed severe Hidradenitis Suppurativa (HS) affecting the axillary, groin, and gluteal regions. Despite undergoing various systemic and intravenous antibiotic therapies, as well as Adalimumab treatment, the HS remained refractory. Adalimumab was discontinued due to a detected ejection fraction of 45% during cardiologic follow-up, likely due to COVID-19 related myocarditis. Following this, the patient was initiated on secukinumab therapy, initially undergoing an induction phase followed by maintenance dosing. Significant improvements were observed in quality of life, pain scores, and HS activity after 5 weeks of secukinumab therapy, with sustained benefits at the 6-month follow-up. Secukinumab was well tolerated, with no reported adverse events. This case underscores the effectiveness and safety of secukinumab as a therapeutic option for refractory HS, particularly in patients with comorbidities such as renal transplant recipients.Keywords: hidradenitis suppurativa, Adalimumab, antibiotic, Secukinumab

Objective: Impetigo herpetiformis (IH) is a rare form of pustular psoriasis which may result in maternal and fetal morbidity and even mortality. Deficiency of interleukin-36 receptor antagonist (DITRA) is the most frequently identified genetic defect of IH. Currently there are no biologics approved for IH despite the revolutionary role of biologics in the treatment of plaque and pustular psoriasis. Anecdotal reports of biologics use in DITRA patients with IH are also limited. Case reports: We present herein a case series of 6 Chinese IH patients harboring IL36RN gene c.115+6T>C mutation during 8 pregnancies, treated with various biologics, including adalimumab, etanercept and secukinumab. Conclusion: Most pregnancy courses were uneventful, except for one woman who had recurrent episodes of decreased fetal heart rate variability after adalimumab injections, which subsided after switching to etanercept. The treatment effectiveness and safety demonstrated in our cases suggested the role of biologics for the treatment of IH in patients with DITRA.

Objective To explore the clinical efficacy and safety of secukinumab in the treatment of childhood generalized pustular psoriasis (GPP) in order to provide a new therapeutic strategy for childhood generalized pustular psoriasis. Methods A retrospective analysis was conducted on the clinical data of 25 children with GPP treated with subcutaneous secukinumab in our department from June 2020 to June 2022. The efficacy was evaluated according to Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) scores, Generalized Pustular Psoriasis Area and Severity Index (GPPASI) scores, Children's Dermatology Life Quality Index (CDLQI) scores, and Depression Self-rating Scale for children (DSRSC) scores. The adverse reactions were also assessed. Results Following secukinumab treatments, the average time of lesion clearance was 3.36±0.99 days. Alleviations of scales and pustules were observed in majority of patients after 2-week treatment. After 28-week treatment, GPPGA score was reduced from 3.56±0.50 at baseline to 0.20±0.50, while GPPASI score was decreased from 34.83±9.24 at baseline to 0.68±1.64. Similarly, both CDLQI and DSRSC scores were decreased 14.96±4.88 to 0.40±0.64 and 11.41±2.54 to 6.64±1.80, respectively. During the course of treatment, upper respiratory tract infections and eczema were observed in 2 cases each. One case each had pain with pruritus on the injection site and headache. No other adverse events were observed. Conclusions Secukinumab is safe and can rapidly improve the erythema, scales and pustules in pediatric generalized pustular psoriasis in addition to the improvements in patients' quality of life and mental health.

Abstract Introduction Psoriasis (PsO) is an immune-mediated chronic inflammatory disease that results in severe outcomes that impact the patient’s quality of life and work productivity. We investigated the effectiveness of secukinumab in patients with chronic plaque psoriasis and psoriatic arthritis (PsA) over a 12-month period. Methods This was a longitudinal, retrospective study of the medical records of 81 patients with psoriasis and/or psoriatic arthritis who had been treated with secukinumab for at least 12 weeks. Results The Psoriasis Area Severity Index (PASI), Body Surface Area (BSA) percentage, and Dermatology Quality of Life Index (DLQI) among patients with PsO and PsO-PsA showed a statistically significant decrease from baseline over 12 months by approximately 9.86, 19.3%, and 9.7, respectively (p values

Background: Radiographic axial spondyloarthritis (r-axSpA), formerly known as ankylosing spondylitis (AS), is a chronic, inflammatory rheumatic disease associated with symptoms such as inflammatory back pain, morning stiffness, and arthritis. First-line recommendations for patients with AS include treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) for reducing pain and stiffness. Objectives: The objective of our study is to evaluate the efficacy and short-term NSAID-sparing effect of secukinumab in patients with AS currently treated with NSAIDs. Design: We assessed the clinical Assessment of SpondyloArthritis International Society (ASAS20) response to secukinumab and evaluated the extent to which the use of concomitant NSAID can be reduced between weeks 4 and 12 in r-axSpA patients treated with secukinumab 150 mg compared with placebo. Methods: ASTRUM was a prospective 24-week randomized controlled trial of adult patients with active r-axSpA [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ⩾4] who had a documented inadequate response to ⩾2 NSAIDs. Patients were randomized (1:1:1) to initiate treatment with subcutaneous secukinumab 150 mg from either week 0 (group 1), week 4 (group 2), or week 16 (group 3). From week 4 onward, tapering of NSAIDs was allowed in all groups. Results: This study included 211 patients (n = 71, 70, and 70 in groups 1, 2, and 3, respectively). ASAS20 response at week 12 for pooled groups 1 and 2 versus group 3 was 51.1% versus 44.3% (p = 0.35). A higher proportion of patients in groups 1 and 2 achieved ASAS40 and BASDAI50 and showed improvements in other secondary clinical outcomes as compared to group 3 at week 16. More patients in groups 1 and 2 versus group 3 stopped their NSAID intake from baseline through week 16. Conclusion: Treatment with secukinumab improved clinical outcomes and showed a short-term NSAID-sparing effect in patients with r-axSpA, even though the primary endpoint was not met.

OBJECTIVE: To evaluate the four kinds of interleukin biological agents of ustekinumab, ixekizumab, secukinumab and guselkumab, so as to provide scientific basis for drug selection and clinical rational drug use in medical institutions. METHODS: According to the Selection and Evaluation Form of Drug Use (Chemical Drugs) List in the Tertiary Public Medical Institutions in Hebei Province published by Hebei Provincial Health Commission, four kinds of interleukin biological agents were comprehensively evaluated from effectiveness, pharmaceutical characteristics, safety, economy and other properties. RESULTS: The total scores of ustekinumab, ixekizumab, secukinumab and guselkumab were 79. 3, 77. 8, 68. 3 and 76. 3 points respectively. Guselkumab could achieve complete clearing of skin lesions, and the drug retention rate was high. Ustekinumab was the “ dual-targeted ” interleukin-12 and interleukin-23 inhibitor for moderately to severely active Crohn’ s disease in addition to psoriasis. Ixekizumab was a non-whole-human biological preparation, with the highest incidence of adverse reactions among the four types of biological preparations, yet was relatively inexpensive. Sekucizumab and ustekinumab were approved for psoriasis in children and adolescents. CONCLUSIONS: Guselkumab may be considered for patients seeking complete clearance and wishing to maintain better outcomes over time. Ustekinumab may be considered for patients with a history of inflammatory bowel disease or a family history of inflammatory bowel disease. Secukinumab and ustekinumab may be considered for pediatric psoriasis. Ixekizumab may be an option for patients wishing to achieve a rapid onset of action and who have limited ability to pay, yet patients who are susceptible to allergies and at high risk for connective tissue disease should be avoided. Ixekizumab and secukinumab may cause or aggravate inflammatory bowel disease and should be used with caution in clinic. [ABSTRACT FROM AUTHOR]

For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. Studies regarding infection rates after vaccination are lacking. Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases. [ABSTRACT FROM AUTHOR]

Introduction: Circulating T follicular helper (cTfh) cells and circulating T peripheral helper (cTph) cells (which share common characteristics with the cTfh population) are implicated in the pathogenesis of immune-mediated and autoimmune diseases such as psoriasis (Ps). Their close interplay with the interleukin 17 (IL-17) axis and the ex vivo effect of IL-17-targeting biologic agents used to treat Ps on them are elusive. This study aimed to investigate the effect of biologics targeting IL-17 on cTfh and cTph cell subpopulations isolated from the blood of patients with Ps. Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from patients with Ps at treatment initiation and three months later. Samples were also collected from controls. Cells were stained using monoclonal antibodies. Flow cytometry assessed the fraction of cTfh (CD3+CD4+CXCR5+) and cTph (CD3+CD4+CXCR5-PD-1hi) cells.. Results: Flow cytometric analysis showed increased fractions of activated cTfh subsets including ICOS+ and ICOS+ PD-1+ expressing cells, in patients compared to controls. Biologic blocking of IL-17A diminished the cTfh population. Furthermore, ICOS+ and ICOS+ PD-1+ sub-populations were also inhibited. Finally, the cTph cell fraction significantly decreased after three months of successful treatment with biologics. Conclusion: Early anti-IL-17-mediated clinical remission in Ps is associated with decreased cTfh and cTph cell subpopulations. [ABSTRACT FROM AUTHOR]

Purpose: Multiple biological therapies have been developed for the treatment of inflammatory diseases, including moderate to severe plaque psoriasis. Choosing the optimal treatment for psoriasis can depend on several factors and is strongly influenced by a drug's efficacy and safety profile. Continuous treatment with biological therapies is recommended to achieve effective disease management in patients with psoriasis. However, in real-world, patients often discontinue biologic therapy within the first year of treatment. Therefore, in this study, we aimed to investigate the effectiveness and drug survival of two anti-interleukin 17 agents (ixekizumab and secukinumab) in a group of adult patients with moderate to severe psoriasis from Bucharest, Romania. Patients and Methods: We designed an observational, non-interventional, retrospective study of 255 adult patients with moderate to severe psoriasis receiving ixekizumab and secukinumab. We performed descriptive statistics and inferential methods, such as z-test, median test and Kaplan Meier curve comparison, to characterize the groups with two biological treatments. Results: Patients treated with ixekizumab had a longer drug survival compared to those treated with secukinumab with lower risks of non-persistence, discontinuation and switching therapy. Patients age-groups and psoriasis durations found to be significant factors in drug survival. Conclusion: This study contributes to the understanding of the drug survival profile and the factors that may influence it in ixekizumab and secukinumab treatment in a real-world setting.

Objectives: The aim of this study was to evaluate the impact of obesity on the treatment response to secukinumab and drug survival rate in patients with ankylosing spondylitis (AS). Methods: We performed an observational cohort study that included AS patients based on the biological drug database in Turkey (TURKBIO) Registry between 2018 and 2021. The patients were divided into three groups: normal [body mass index (BMI) < 25 kg/m2], overweight (BMI: 25–30 kg/m2), and obese (BMI ≥ 30 kg/m2). Disease activity was evaluated at baseline, 3, 6, and 12 months. Drug retention rates at 12 months were also investigated. Results: There were 166 AS patients using secukinumab (56.6% male, mean age: 44.9 ± 11.6 years). The median follow-up time was 17.2 (3–33.2) months. Forty-eight (28.9%) patients were obese. The mean age was higher in the obese group than in others (P = .003). There was no statistically significant difference in Bath Ankylosing Spondylitis Disease Activity Index 50, Assessment of SpondyloArthritis international Society 20 (ASAS20), ASAS40, Ankylosing Spondylitis Disease Activity Score (ASDAS) low disease activity, and ASDAS clinically important improvement responses between the three groups at 3, 6, and 12 months, although they were numerically lower in obese patients. Drug retention rates at 12 months were similar in all groups (P > .05). Conclusions: This study suggested that obesity did not affect secukinumab treatment response and drug retention in AS patients.

Background/Objectives: Nail psoriasis, a subtype of psoriasis, can cause significant pain, disability, and reduced quality of life. Despite the established efficacy of anti‐IL17 secukinumab in improving skin psoriasis, there is a lack of clinical trials focusing on nail psoriasis as primary endpoint. This study aims to investigate the efficacy of secukinumab in treating nail psoriasis in patients with moderate to severe psoriasis. Methods: We prospectively recruited patients newly diagnosed with moderate to severe psoriasis in single centre from January 2021 to January 2022 who were treated with secukinumab. Results: A total of 16 patients consisting of 9 males and 7 females were included. Their mean age was 38.88 ± 10.29 years. They had an average initial Nail Psoriasis Severity Index (NAPSI) score of 45.06 ± 20.39 and an average NAPSI score at 12 weeks of 8.94 ± 13.50, showing a significant (p < 0.05) decrease of NAPSI score after 12 weeks of secukinumab treatment. After 24 weeks of treatment, NAPSI score was decreased to 5.12 ± 8.52. Conclusion: Secukinumab rapidly improved nail psoriasis after 12 weeks of treatment, with further enhancement at 24 weeks, suggesting its potential as a potent therapeutic option for nail psoriasis.

The interleukin (IL)-17 axis is involved in many inflammatory and autoimmune diseases. Secukinumab, an IL-17 inhibitor, has been approved for psoriasis treatment. There are accumulating cases of lupus erythematosus induced by IL-17 inhibition. Lupus nephritis after IL-17 inhibition has not been reported. We report the case of a 57-year-old man who developed membranous lupus nephritis after secukinumab treatment for psoriasis. Anti-SSA and PM-Scl antibodies were positive. dsDNA, anti-Smith, and anti-histone antibodies were negative, and serum complement was low. Secukinumab was discontinued, while tacrolimus was initiated, subsequently switched to cyclosporin, belimumab, glucocorticosteroid, and hydroxychloroquine with a good response. The relationship between lupus erythematosus and IL-17 inhibition requires further research. [ABSTRACT FROM AUTHOR]

Targeting IL-17A using Secukinumab, a humanized monoclonal immunoglobulin G1 (IgG1)/κ against IL-17A is a therapeutic option for immune-mediated disorders such as psoriasis and ankylosing spondylitis. The US Food and Drug Administration and the European Medicines Agency have approved it for the treatment of moderate to severe plaque psoriasis, active psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondylarthritis. Recently it has also been approved for use in children with severe plaque psoriasis, active psoriatic arthritis, and enthesitis-related arthritis. This review focuses on the role of Secukinumab in the management of children and adolescents with enthesitis-related arthritis and psoriatic arthritis. We discuss the salient findings of pivotal RCTs and other studies supporting the use of Secukinumab in adults and children, in particular, focusing on its safety and efficacy. Secukinumab is a therapeutic target for psoriasis, psoriatic arthritis, and spondyloarthropathies in both adults and children. No major safety signals are observed with its use in short-term follow-up. Thus far, Secukinumab has not been found to significantly increase the risk of tuberculosis (TB). [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusion Generalized pustular psoriasis (GPP) is a rare, potentially life‐threatening skin disease often requiring long‐term therapy. We aimed to evaluate the use of Interleukin (IL)‐17A inhibitors (secukinumab and ixekizumab) in GPP patients over 96 weeks.We retrospectively analyzed a case series of 18 patients with GPP who received secukinumab (n = 13) and ixekizumab (n = 5) therapy with a 96‐week follow‐up period. The primary effectiveness analysis included determining the percentage of patients who achieved ≥90% or 100% improvement in the Generalized Pustular Psoriasis Area and Severity Index (GPPASI) score. Adherence was captured using the medication possession ratio (MPR).Using the as‐observed (AO) method, 87% and 67% of patients treated with secukinumab or ixekizumab achieved GPPASI 90 and 100 responses, respectively. At Week 96, the mean GPPASI improvements from baseline GPPASI were 96.3% (95% CI: 0.91–1.01) using the AO method. After Week 48, 14 patients tapered (n = 8) or terminated (n = 6) the treatment. High‐adherence therapy (MPR ≥ 80%) was significantly superior to the low‐adherence group in the rate of patients achieving a GPPASI 100 response (AO, 100% vs. 38%, P < 0.05). By Week 96, 5 (27.8%) patients had new GPP flares, and 4 (80%) were in the low‐adherence group. No new safety signals occurred.IL‐17A inhibitors led to effective and sustained improvement in GPP patients, and high‐adherence therapy had long‐term positive effects on skin clearance. Given its relapsing nature, improving compliance is beneficial for long‐term clinical management. [ABSTRACT FROM AUTHOR]

(1) Objective: The main aims of our study were to explore the drug survival and effectiveness of secukinumab in patients with axial spondyloarthritis (axSpA). (2) Methods: We underwent a retrospective analysis of consecutive axSpA treated with secukinumab as a first line of biologics or at switch in a biologic-experienced population. Efficacy data, indicating improvement in inflammation parameters (such as C-reactive protein and erythrocyte sedimentation rate) and disease activity scores (such as Ankylosing Spondylitis Disease Activity Score [ASDAS-CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), and patient-reported outcomes (pain), were assessed at 6, 12, 24, 36 and 48 months. The drug survival rate, dropout rate and discontinuation reasons (efficacy versus safety) of secukinumab were assessed in subgroup analysis (axSpA with and without exposure to biologics). (3) Results: In total, 46 patients were exposed to the IL-17A inhibitor secukinumab. The drug survival for axSpA patients 59.7% at 12 months and 31.3% at 24 months. There were no statistically significant differences in the median drug survival between biologic-naïve versus biologic-experienced subgroups. (4) Conclusions: Secukinumab has demonstrated effectiveness and safety in treating a cohort of axSpA patients in real-world settings, with a notable retention rate of the drug.

OBJECTIVE: Psoriasis and psoriatic arthritis (PsA) are closely linked to cancer, as supported by the literature. Systemic treatments for psoriasis and PsA, namely non-biological disease-modifying anti-rheumatic drugs (DMARDs), have been associated with increased cancer risk in both conditions. New, more effective biological DMARDs (bDMARDs) do not seem to be associated with higher overall cancer risk compared to those not receiving bDMARDs, opening up possibilities for treating patients with previous or ongoing oncological disease alongside psoriasis and PsA. However, limited literature exists on treating PsA patients with cancer with bDMARDs. This study aims to assess the safety of secukinumab, a bDMARD, in patients with PsA and concurrent cancer. Here, we describe a case series of four patients with PsA treated with bDMARD secukinumab and review the literature on the subject. CASE SERIES: We assessed the laboratory parameters and clinical characteristics of 4 patients with PsA treated with the bDMARD secukinumab and followed up until 30 months. Three patients had oncological disease in remission, while one had active neoplasia. No cancer progression was observed during the treatment of these patients with secukinumab. CONCLUSIONS: In conclusion, our case series, consisting of four PsA patients with concurrent neoplasia treated with secukinumab, showed no evidence of cancer progression and represents the first case of PsA described in the literature treated during active oncological disease, lending support to the safety of secukinumab for the treatment of patients with PsA and concomitant neoplasia.

Giant cell arteritis (GCA) is an ophthalmic emergency because of its potential for irreversible blindness. Clinicians should be aware of the variable presentations, laboratory features, and evaluation of GCA because earlier diagnosis and treatment can prevent loss of sight. We have provided an update on recent advances in the diagnosis, treatment, and prognosis of GCA. We searched the PubMed database from 1990 to 2023 for relevant reviews, case reports, and trials. Emerging treatments for GCA are additionally summarized. Clinicians should be aware of common and uncommon presentations of GCA. A high index of suspicion is essential for detection of GCA in elderly patients, and early treatment can prevent or reduce permanent vision loss. GCA is a true ophthalmic emergency and high dose empiric glucocorticoid treatment is recommended followed by confirmation with temporal artery ultrasound and/or biopsy. New vascular imaging methods and approaches to acute and maintenance therapy for GCA have emerged over the past several years. Temporal artery ultrasound shows increasing sensitivity and specificity and may eventually replace 'gold standard' histopathologic confirmation by temporal artery biopsy. Emerging steroid-sparing therapies like tocilizumab may reduce prednisone dosages and induce long-term remission with less systemic adverse effects. [ABSTRACT FROM AUTHOR]

Objective. To assess the humoral response to the BNT162b2 mRNA vaccine among patients with spondyloarthritis (SpA) receiving secukinumab (SEC) compared to those receiving tumor necrosis factor inhibitors (TNFi) and immunocompetent controls. Methods. Consecutive patients with psoriatic arthritis or axial SpA receiving SEC (n = 37) or TNFi (monotherapy, n = 109; + methotrexate [MTX], n = 16), immunocompetent controls (n = 122), and patients with rheumatoid arthritis (RA) receiving TNFi therapy (controls, n = 50) were vaccinated with 2 or 3 doses of the BNT162b2 vaccine. We evaluated humoral response, adverse events, and disease activity, and monitored for breakthrough coronavirus disease 2019 (COVID-19) postvaccination. Results. The 2-dose vaccine regimen induced a comparable seropositive response in all study groups. S1/S2 antibody titers (in binding antibody units/mL; mean [SD]) were higher in the SEC group vs the TNFi + MTX-SpA and TNFi-RA groups (192.5 [68.4] vs 104.6 [46.9], P < 0.001, and 143.1 [81.9], P = 0.004). After 6 months, 96.3%, 96.6%, and 80.9% of the SEC, immunocompetent, and TNFi monotherapy-SpA groups (P = 0.10), respectively; 66.7% of the TNFi + MTX-SpA group (P = 0.03); and 63% of the TNFi-RA group (P = 0.004) remained seropositive. S1/S2 antibody titer decline was steeper in the TNFi groups than the SEC group. After the third dose, 100% of the SpA and immunocompetent and 88.9% of the TNFi-RA (P = 0.25) groups were seropositive. Rate of breakthrough COVID-19 infection was higher in the TNFi groups than in the SEC group (36-37.5% vs 10.8%). No significant between-group differences were observed for postvaccination disease activity and adverse events. Conclusion. SEC did not interfere with the immunogenic response to BNT162b2 vaccine in patients with SpA; however, TNFi therapy was associated with lower S1/S2-antibody titers, faster decline, and higher rate of breakthrough infections.

Background: Interleukin (IL)-17A is essential for intestinal mucosal integrity, contributing to the prevention of detrimental immunity such as infectious colitis and inflammatory bowel disease (IBD). Indeed, neutralization of IL-17A has been abandoned as a therapeutic principle in IBD because of increased disease activity. However, it is controversial whether IL-17A inhibitors increase the risk of developing colitis in patients who do not have underlying IBD. Here, we present two cases of different forms of colitis that occurred during treatment with two IL-17A inhibitors, secukinumab and ixekizumab. Case presentations: We report the case of a 35-year-old female with SAPHO (synovitis–acne–pustulosis–hyperostosis–osteitis) syndrome who was admitted due to severe colitis with bloody diarrhea, fever, abdominal pain and weight loss after receiving secukinumab for 3 months as well as the case of a 41-year-old male with psoriatic arthritis who presented himself to the outpatient clinic with bloody stools, abdominal pain and nausea 5 months after changing his therapy from secukinumab to ixekizumab. In both patients, treatment with IL-17A-inhibitors was stopped and tumor necrosis factor inhibitors were started. Both patients recovered, are clinically stable and show no more signs of active colitis. Conclusion: The role of IL-17A inhibitors in the pathogenesis of infectious colitis and new-onset IBD is not fully understood and requires further research. Patients receiving IL-17A-inhibitor therapy should be carefully screened and notified of the possible side effects. [ABSTRACT FROM AUTHOR]

IL-23 is a cytokine produced by myeloid cells that drives the T helper 17 pathway and plays an essential role in the pathophysiology of plaque psoriasis. IL-23 activation initiates a cascade of cytokines subsequently inducing the expression of many psoriasis-related proteins. This study aimed to better understand the underlying mechanisms driving the differences between IL-23 and IL-17A blockade in patients with psoriasis and their implications for durability of clinical responses. Serum and/or skin biopsies were isolated from patients treated with guselkumab or secukinumab for evaluation of potential biomarkers of pharmacodynamic response to treatment. Guselkumab treatment led to significantly greater reductions of IL-17F and IL-22 serum levels than treatment with secukinumab at weeks 24 and 48, demonstrating sustained regulation of the IL-23/T helper 17 pathway. Analyses of proteomic and transcriptomic profiles of patient sera and skin biopsies demonstrated differential regulation of proteins involved in chemokine, TNF, and relevant immune signaling pathways to a greater degree with guselkumab than with secukinumab treatment. These data provide insights into the differences between the mechanisms and impact of IL-23 and IL-17A blockade in psoriasis, with implications for efficacy observations and treatment paradigms. Trial Registration: The original study was registered at ClinicalTrials.gov (NCT03090100).

BackgroundGeneralized pustular psoriasis (GPP) is a severe type of psoriasis. The current treatment primarily relies on corticosteroids and immunosuppressants. In recent years, biologics have been increasingly utilized in the treatment of this disease, and have demonstrated good clinical efficacy. However, children and adolescents are primarily treated with immunosuppressants, which have limited clinical application due to the serious side effects they may cause. At the same time, the effectiveness of current treatments is unsatisfactory. Secukinumab has been widely reported to be effective and safe in treating this disease. However, there are still insufficient data on its use in treating GPP in children.ObjectiveTo conduct a systematic review of the existing literature on the use of secukinumab for treating generalized pustular psoriasis in children and adolescents, and to evaluate its clinical effectiveness and safety.MethodsWe conducted a systematic review of all the literature reporting on the treatment of GPP in children and adolescents with secukinumab.ResultsA total of 7 papers (46 patients) were included in this study. After 12 weeks of treatment, all 46 participants were able to achieve a GPPASI score of 90 or higher, with approximately 96% of patients achieving complete clearing of the lesions (GPPASI 100 or JDA0). Adverse events were reported in 8 patients, the rate of adverse reactions was approximately 17%.ConclusionThe treatment of GPP in children and adolescents with secukinumab has a rapid onset of action and a high safety profile. However, the results of the literature may be influenced by publication bias.

Purpose: To demonstrate the effective integration of pharmacometrics and pharmacovigilance in managing medication errors, highlighted by a case involving secukinumab in a patient with hidradenitis suppurativa. Methods: We present the case of a 41-year-old male with progressive hidradenitis suppurativa, unresponsive to multiple antibiotic regimens and infliximab treatment. Due to a medication error, the patient received 300 mg of secukinumab daily for 4 days instead of weekly, totaling 1200 mg. The regional pharmacovigilance center assessed potential toxicity, and a pharmacometric analysis using a population pharmacokinetic model was performed to inform dosing adjustments. Results: Clinical data indicated that the received doses were within a non-toxic range. No adverse effects were observed. Pharmacometric simulations revealed a risk of underexposure due to the dosing error. Based on these simulations, it was recommended to restart monthly secukinumab injections on day 35 after the initial dose. Measured plasma concentrations before re-administration confirmed the model's accuracy. Conclusion: This case highlights the crucial collaboration between clinical services, pharmacovigilance, and pharmacometrics in managing medication errors. Such interdisciplinary efforts ensure therapeutic efficacy and patient safety by maintaining appropriate drug exposure levels. [ABSTRACT FROM AUTHOR]

Objective To observe the efficacy of secukinumab in the treatment of severe plaque psoriasis with abnormal liver function and the changes in liver function after the treatment. Methods Seven patients with severe plaque psoriasis with abnormal liver function were subcutaneously given secukinumab 300 mg/time, once-weekly from weeks 0 to 4, followed by once every 4 weeks. Routine blood test, liver and kidney functions, blood lipids and glucose were tested at weeks 1, 2, 3, and 4, and every 4 weeks thereafter until week 32. At the same time, the psoriatic lesion area and severity index (PASI), physician global assessment (PGA), and dermatology life quality index (DLQI) were recorded to assess the efficacy and safety. Results The PASI scores, PGA scores and DLQI were changed significantly from the baseline at all time points (P

Clinical observations of three patients aged 26, 43 and 37 years with severe psoriasis and psoriatic arthritis are presented. Clinical examples show the experience of effective treatment of patients with psoriasis and psoriatic arthritis using anti-cytokine therapy with an interleukin-17 inhibitor, initiated when the disease progresses. The clinical picture of the presented observations was characterized by an aggressive course of the skin and articular process, torpidity to basic therapy, despite the young age of the patients. It has been shown that the early termination of the progression of the inflammatory process in psoriasis with the use of genetically engineered biological therapy with secukinumab leads to a decrease in symptoms, both on the part of the skin and manifestations of the disease on the part of the musculoskeletal system. The high efficacy and safety of the drug allow complete control of the disease and improve the quality of life in patients suffering from severe forms of dermatosis.
