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 (PsoProtectMe), 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., Competing Interests: Conflict of interests J.W. has presented talks for Abbott, AbbVie, Bayer, Boehringer Ingelheim, Chiesi, Merck and Roche.

Background: Sufficient data on access to systemic treatment for patients with psoriasis living in Latin America (LA) including Brazil and Chile are lacking. Understanding the availability and limiting factors of access to treatments can help to improve patient care and decrease long-term healthcare costs., Objectives: In association with the Global Psoriasis Atlas, this cross-sectional survey study analysed the availability and insurance reimbursement of systemic treatments for adult patients with psoriasis in Brazil and Chile., Methods: A multicentre, cross-sectional Global Healthcare Study on Psoriasis was performed in Brazil and Chile in 2020. For each eligible adult patient with psoriasis, doctors and nurses completed a 48-item questionnaire about clinical aspects of psoriasis including the Psoriasis Area Severity Index (PASI), body surface area (BSA) score and the Dermatology Life Quality Index (DLQI), as well as the availability of systemic treatments and insurance reimbursement status. Between-country differences were compared with Wilcoxon rank sum tests for continuous variables, and a χ2-test or Fisher's exact test, where appropriate, for categorical variables. The median and interquartile range (IQR) was calculated for non-normal distributed data., Results: A total of 1424 patients with psoriasis from 43 centres [27 centres in Brazil (n = 826) and 16 in Chile (n = 598)], were included with a mean (SD) age of 49.1 (16.3) and 49.2 (15.1) years, respectively. Unstratified analyses revealed that patients with psoriasis in Chile had more severe disease than those in Brazil [PASI 11.6 vs. 8.4 (P < 0.001) and BSA 14.7 vs. 12.0 (P = 0.003), respectively]. For patients with moderate-to-severe psoriasis, defined as PASI and/or BSA ≥ 10, systemic nonbiologic drugs were available (81.2% in Brazil and 65.3% in Chile, P ≤ 0.001), but only 37.0% of patients in Brazil and 27.3% in Chile received biologics (P = 0.01). Lack of availability and/or lack of insurance reimbursement for biologic drugs for patients with moderate-to-severe psoriasis was reported for 22.2% (50 of 225) in Brazil and 67.9% (148 of 218) in Chile (P < 0.001). Patients with no access to biologic therapies due to lack of availability/insurance reimbursement had a median PASI of 9.15 (IQR 3.00-14.25) in Brazil and 12.0 (IQR 5.00-19.00) in Chile (P = 0.007), as well as a median BSA of 7.0 (IQR 3.00-15.00) and 12.0 (IQR 5.00-22.50) (P = 0.002), and median DLQI of 11.0 (6.00-15.00) and 21.0 (6.50-25.00) (P = 0.007), respectively., Conclusions: Chilean patients had significantly more severe psoriasis compared with Brazilian patients in our study. While nonbiologic treatments for moderate-to-severe psoriasis were available in both LA countries, there is a high need for improvement in access to more effective psoriasis treatments including biologics. Our results highlight a significant gap between treatment recommendations in international psoriasis guidelines and real-world situations in Brazil and Chile., Competing Interests: Conflicts of interest J.-T.M. is an employee of USZ and has served as an advisor and/or received speaking fees and/or participated in clinical trials sponsored by AbbVie, Almirall, Amgen, BMS, Celgene, Eli Lilly, Janssen-Cilag, LEO Pharma, MSD, Novartis, Pfizer, Pierre Fabre, Roche, Sanofi and UCB.

Importance: A clear dosing regimen for methotrexate in psoriasis is lacking, and this might lead to a suboptimal treatment. Because methotrexate is affordable and globally available, a uniform dosing regimen could potentially optimize the treatment of patients with psoriasis worldwide., Objective: To reach international consensus among psoriasis experts on a uniform dosing regimen for treatment with methotrexate in adult and pediatric patients with psoriasis and identify potential future research topics., Design, Setting, and Participants: Between September 2020 and March 2021, a survey study with a modified eDelphi procedure that was developed and distributed by the Amsterdam University Medical Center and completed by 180 participants worldwide (55 [30.6%] resided in non-Western countries) was conducted in 3 rounds. The proposals on which no consensus was reached were discussed in a conference meeting (June 2021). Participants voted on 21 proposals with a 9-point scale (1-3 disagree, 4-6 neither agree nor disagree, 7-9 agree) and were recruited through the Skin Inflammation and Psoriasis International Network and European Academy of Dermatology and Venereology in June 2020. Apart from being a dermatologist/dermatology resident, there were no specific criteria for participation in the survey. The participants worked mainly at a university hospital (97 [53.9%]) and were experienced in treating patients with psoriasis with methotrexate (163 [91.6%] had more than 10 years of experience)., Main Outcomes and Measures: In a survey with eDelphi procedure, we tried to reach consensus on 21 proposals. Consensus was defined as less than 15% voting disagree (1-3). For the consensus meeting, consensus was defined as less than 30% voting disagree., Results: Of 251 participants, 180 (71.7%) completed all 3 survey rounds, and 58 participants (23.1%) joined the conference meeting. Consensus was achieved on 11 proposals in round 1, 3 proposals in round 2, and 2 proposals in round 3. In the consensus meeting, consensus was achieved on 4 proposals. More research is needed, especially for the proposals on folic acid and the dosing of methotrexate for treating subpopulations such as children and vulnerable patients., Conclusions and Relevance: In this eDelphi consensus study, consensus was reached on 20 of 21 proposals involving methotrexate dosing in patients with psoriasis. This consensus may potentially be used to harmonize the treatment with methotrexate in patients with psoriasis.

There are several studies on the benefits of using TNFα antagonists in the treatment of psoriasis, but few studies addressing the interaction of these drugs with chronic infections. We report the case of a 52-year-old patient diagnosed with psoriasis refractory to traditional systemic agents, who was treated with biologic therapies. After one year of treatment with biologic agents, the patient was diagnosed with Chagas Disease.
