Background Few studies have used real-world data to investigate the association between biologic therapy survival and age at psoriasis onset or HLA-C*06:02 status in patients with moderate-to-severe psoriasis. The robustness of these studies is limited by small sample size, short follow-up and diverse safety and effectiveness measures. Objectives To describe biologic survival and explore whether the response to biologics is modified by age at psoriasis onset or HLA-C*06:02 status in patients with moderate-to-severe psoriasis. Methods Data from patients in the UK and the Republic of Ireland registered in the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) from 2007 to 2022 on a first course of adalimumab, etanercept, secukinumab or ustekinumab with at least 6 months' follow-up and a subset of BADBIR patients with available HLA-C*06:02 information registered to Biomarkers and Stratification To Optimise outcomes in Psoriasis (BSTOP) were analysed. Patients aged ≥ 50 years at treatment initiation were classified into early-onset psoriasis (EOP) (presenting in patients ≤ 40 years of age) and late-onset psoriasis (LOP) (presenting in patients > 40 years of age). BADBIR patients with available information in BSTOP were categorized as HLA-C*06:02− or HLA-C*06:02 +. Biologic survival was defined as treatment discontinuation associated with ineffectiveness or occurrence of adverse events (AEs). Adjusted survival function and hazard ratio (aHR) with 95% confidence interval (CI) were estimated using a flexible parametric model to compare discontinuing therapy between age at psoriasis onset and HLA-C*06:02 groups. Each model included exposure (biologics), effect modifier (age at onset or HLA-C*06:02 status), interaction terms and several baseline demographic, clinical and disease severity covariates. Results Final analytical cohorts included 4250 patients in the age at psoriasis onset group [2929 EOP (69%) vs. 1321 LOP (31%)] and 3094 patients in the HLA-C*06:02 status group [1603 HLA-C*06:02+ (52%) vs. 1491 HLA-C*06:02− (48%)]. There was no significant difference between EOP and LOP in drug survival associated with ineffectiveness or AEs for any biologics. However, compared with patients who were HLA-C*06:02−, patients who were HLA-C*06:02 + were less likely to discontinue ustekinumab for reasons associated with ineffectiveness (aHR 0.56, 95% CI 0.42–0.75). Conclusions HLA-C*06:02, but not age at psoriasis onset, is a predictive biomarker for biologic survival in patients with psoriasis. Findings from this large cohort provide further, important information to aid clinicians using biologic therapies to manage patients with psoriasis. [ABSTRACT FROM AUTHOR]

This document is a supplementary information section of a study conducted by the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR). The study aimed to investigate the factors associated with super responders (SRs) and super nonresponders (SNRs) to biologic therapies in patients with psoriasis. The study found that female sex, shorter study follow-up, higher Dermatology Life Quality Index (DLQI), high frequency of adalimumab, lower frequency of ustekinumab at registration, and higher number of comorbidities were associated with SNRs compared with SRs. The study also mentioned that genetic factors, socioeconomic status, lifestyle factors, adherence to medication, immunogenicity, microbiome, epigenetics, and serum drug levels may play a role in determining treatment response.

Objective Musculoskeletal pain is a common risk factor for co-morbid conditions and might increase the risk of poor outcomes. The objective was to determine whether patients with pre-existing musculoskeletal pain have an increased risk for mortality following a new diagnosis of a co-morbid condition. Methods Patients aged ≥45 years with a new diagnosis of acute coronary syndrome (ACS), stroke, cancer, dementia or pneumonia recorded in a UK electronic primary care database linked to hospital and mortality records were examined. The association of mortality with musculoskeletal pain (inflammatory conditions, OA and regional pain) was determined. Results The sample size varied from 128 649 (stroke) to 406 289 (cancer) by cohort, with 22–31% having pre-existing musculoskeletal conditions. In the ACS cohort, there was a higher rate of mortality for all musculoskeletal types. There were also higher unadjusted mortality rates in patients with inflammatory arthritis compared with those without musculoskeletal pain in the stroke, cancer and dementia cohorts and for patients with OA in the stroke and cancer cohorts. After adjustment for the number of prescribed medications and age, the increased risk of mortality remained only for patients with inflammatory arthritis in the ACS cohort (adjusted hazard ratio = 1.07; 95% CI 1.03, 1.10). Conclusion Older adults with inflammatory arthritis and OA have increased risk of mortality when they develop a new condition, which seems to be related to the prescription of multiple medicines. Pre-existing musculoskeletal pain is an indicator of a complex patient who is at risk of poorer outcomes at the onset of new illnesses. [ABSTRACT FROM AUTHOR]

Background Most information on the comparative effectiveness and survival of methotrexate (MTX) and adalimumab (ADA) in the treatment of psoriasis is from randomized control trials and may not translate to the everyday clinical setting. Objectives To determine the real-world effectiveness and survival of MTX and ADA in patients with moderate-to-severe psoriasis registered in the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR). Methods Eligible patients were registered in BADBIR, ≥ 16 years of age and receiving a first course of MTX or ADA between September 2007 and December 2021, with ≥ 6 months of follow-up. Effectiveness was defined as achieving an absolute Psoriasis Area and Severity Index (PASI) ≤ 2 reported ≥ 13 weeks after the treatment start date until the stop date. The average treatment effect (ATE) was estimated using inverse probability of treatment weighting with propensity score, including baseline covariates. ATE results were presented as risk ratios (RR). A flexible parametric model was used to estimate adjusted standardized average survival, defined as treatment discontinuation associated with ineffectiveness or the occurrence of adverse events (AEs) at 6, 12 and 24 months. Restricted mean survival time (RMST) at 2 years of treatment exposure was calculated. Results In total, 6575 patients (median age 44 years; 44% female) were analysed; 2659 (40.4%) were prescribed MTX and 3916 (59.5%) ADA. The proportion of patients achieving PASI ≤ 2 was higher in the ADA cohort (77.4%) than in the MTX cohort (37.4%). ADA was more effective than MTX [RR 2.20, 95% confidence interval (CI) 1.98–2.45]. Overall survival associated with ineffectiveness or AEs was lower in the MTX cohort than in the ADA cohort at 6 months [survival estimate 69.7 (95% CI 67.9–71.5) vs. 90.6 (95% CI 89.8–91.4)], 1 year [survival estimate 52.5 (95% CI 50.4–54.8) vs. 80.6 (95% CI 79.5–81.8)] and 2 years [survival estimate 34.8 (95% CI 32.5–37.2) vs. 68.6 (95% CI 67.2–70.0)]. The difference in RMST (years) overall, or when stratified by ineffectiveness and AEs, was 0.53 (95% CI 0.49–0.58), 0.37 (95% CI 0.33–0.42) and 0.29 (95% CI 0.25–0.33), respectively. Conclusions Patients on ADA were twice as likely to be clear or nearly clear of psoriasis and were less likely to discontinue their medication than patients on MTX. Findings from this real-world cohort provide important information to aid clinicians managing patients with psoriasis. [ABSTRACT FROM AUTHOR]

Background Real-world data evaluating effectiveness and persistence of systemic therapies for patients with psoriasis are limited. Objectives To determine the effectiveness and persistence of acitretin, ciclosporin, fumaric acid esters (FAEs) and methotrexate in patients with moderate-to-severe psoriasis. Methods Data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR), a prospective, multicentre pharmacovigilance register of patients with moderate-to-severe psoriasis receiving biologic and/or conventional systemic therapies, were analysed. Eligible patients were ≥ 16 years of age receiving a first course of acitretin, ciclosporin, FAEs or methotrexate between 2007 and 2021 with ≥ 6 months' follow-up. Effectiveness was defined as achieving absolute Psoriasis Area and Severity Index (aPASI) ≤ 2 reported ≥ 4 weeks after treatment start date until date of cessation. To identify baseline clinical variables associated with treatment effectiveness, we used multivariable logistic regression models estimating the adjusted odds ratio (aOR) of achieving aPASI ≤ 2. To describe drug persistence associated with ineffectiveness, occurrence of adverse events or other reasons for discontinuation, survival estimates with 95% confidence intervals (CIs) were obtained using a flexible parametric model. Results were obtained using multiple imputed data. Results In total, 5430 patients were included in the analysis. Overall, 1023 (19%) patients were receiving acitretin, 1401 (26%) patients were on ciclosporin, 347 (6%) patients were on FAEs, and 2659 (49%) patients were receiving methotrexate at registration. The proportion of patients who achieved aPASI ≤ 2 was lower for those treated with acitretin [ n = 118 (21%)] compared with those receiving ciclosporin [ n = 233 (34%)], FAEs [ n = 43 (29%)] and methotrexate [ n = 372 (32%)]. Factors associated with ineffectiveness included prior experience to previous nonbiologic systemic therapies (acitretin) (aOR 0.64, 95% CI 0.42–0.96), male sex (methotrexate) (aOR 0.58, 95% CI 0.46–0.74), comorbidities (aOR 0.70, 95% CI 0.51–0.97) and alcohol consumption (≤ 14 units per week) (ciclosporin) (aOR 0.70, 95% CI 0.50–0.98). Persistence associated with all reasons for discontinuation showed better survival for methotrexate compared with acitretin, ciclosporin and FAEs cohorts at 12 months [survival estimate 46.1 (95% CI 44.0–48.3), 31.9 (95% CI 29.4–34.7), 30.0 (95% CI 27.5–32.4) and 35.0 (95% CI 29.9–40.9), respectively]. Conclusions The real-world effectiveness and persistence of acitretin, ciclosporin, FAEs and methotrexate were generally low. Previous nonbiologic systemic therapies, male sex, comorbidities and alcohol consumption were risk factors associated with treatment ineffectiveness. [ABSTRACT FROM AUTHOR]

Background Nonadherence to immune-modifying therapy is a complex behaviour which, before the COVID-19 pandemic, was shown to be associated with mental health disorders in people with immune-mediated diseases. The COVID-19 pandemic has led to a rise in the global prevalence of anxiety and depression, and limited data exist on the association between mental health and nonadherence to immune-modifying therapy during the pandemic. Objectives To assess the extent of and reasons underlying nonadherence to systemic immune-modifying therapy during the COVID-19 pandemic in individuals with psoriasis, and the association between mental health and nonadherence. Methods Online self-report surveys (PsoProtect Me), including validated screens for anxiety and depression, were completed globally during the first year of the pandemic. We assessed the association between anxiety or depression and nonadherence to systemic immune-modifying therapy using binomial logistic regression, adjusting for potential cofounders (age, sex, ethnicity, comorbidity) and country of residence. Results Of 3980 participants from 77 countries, 1611 (40.5%) were prescribed a systemic immune-modifying therapy. Of these, 408 (25.3%) reported nonadherence during the pandemic, most commonly due to concerns about their immunity. In the unadjusted model, a positive anxiety screen was associated with nonadherence to systemic immune-modifying therapy [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.07–1.76]. Specifically, anxiety was associated with nonadherence to targeted therapy (OR 1.41, 95% CI 1.01–1.96) but not standard systemic therapy (OR 1.16, 95% CI 0.81–1.67). In the adjusted model, although the directions of the effects remained, anxiety was not significantly associated with nonadherence to overall systemic (OR 1.20, 95% CI 0.92–1.56) or targeted (OR 1.33, 95% CI 0.94–1.89) immune-modifying therapy. A positive depression screen was not strongly associated with nonadherence to systemic immune-modifying therapy in the unadjusted (OR 1.22, 95% CI 0.94–1.57) or adjusted models (OR 1.14, 95% CI 0.87–1.49). Conclusions These data indicate substantial nonadherence to immune-modifying therapy in people with psoriasis during the pandemic, with attenuation of the association with mental health after adjusting for confounders. Future research in larger populations should further explore pandemic-specific drivers of treatment nonadherence. Clear communication of the reassuring findings from population-based research regarding immune-modifying therapy-associated adverse COVID-19 risks to people with psoriasis is essential, to optimize adherence and disease outcomes.
