Prevalence of psoriatic arthritis patients achieving minimal disease activity in real-world studies and randomized clinical trials: systematic review with metaanalysis

Objective. To estimate the frequency of patients with psoriatic arthritis (PsA) achieving minimal disease activity (MDA) status in real-world studies and randomized controlled trials (RCT). Methods. A systematic literature search for 2009–2017 was performed in PubMed, Embase, Cochrane Library, and LILACS. Study selection and data extraction were performed by 2 independent researchers. Random-effects single-arm metaanalyses were performed and heterogeneity was assessed using I2. Results. A total of 405 records were identified and 45 studies were analyzed: 39 (86.7%) observational studies and 6 (13.3%) RCT; they included 12,469 patients. The overall prevalence of MDA in cross-sectional studies was 35% (95% CI 30%–41%, I2 = 94%), varying from 17% (95% CI 7%–34%) in patients taking synthetic disease-modifying antirheumatic drugs (DMARD) to 57% (95% CI 41%–71%) in those taking biological DMARD. Prevalence of MDA in cohort studies increased with longer followup time, ranging from 25% (95% CI 15%–40%) with 3- to 4-month followup to 42% (95% CI 38%–45%) with > 24-month followup. Patients with PsA receiving biological DMARD in a real-world context and RCT had similar prevalence of MDA at 6-month followup: 30% (95% CI 21%–41%, I2 = 85%) versus 32% (95% CI 26%–39%, I2 = 79%), respectively. Conclusion. Patients with PsA included in real-world studies had similar prevalence of MDA compared to those in controlled clinical trials. This finding suggests that MDA is a useful treatment target for PsA in the real-world setting.</p

Management of Dactylitis in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

Objective This literature review aimed to identify the most efficacious current interventions for dactylitis and provide up-to-date scientific evidence to support the 2021 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) recommendations on the management of psoriatic arthritis. Methods Original articles published from 2013 to 2020, registered in MEDLINE, Embase, and Cochrane Library, describing interventional trials and reporting dactylitis-related outcomes were included. The 20 members of the GRAPPA dactylitis group were divided into 9 subgroups according to treatment, and members of each group independently extracted data from articles/abstracts corresponding to their group by using a standardized data extraction form. Results Forty-nine publications were analyzed, representing 40 randomized clinical trials (RCTs) and including 16,752 patients. Dactylitis was assessed as a secondary outcome in 97.5% of these trials and more than 40% of RCTs did not employ a specific dactylitis measure or instrument. Conclusion The emergence of agents with novel mechanisms of action in recent years, such as interleukin 17 (IL-17), IL-12/23, IL-23, and Janus kinase inhibitors, has significantly expanded the available treatment options for dactylitis. This article points out the lack of consensus regarding dactylitis assessment and the paucity of data concerning the effect of local steroid injections, nonsteroidal antiinflammatory drugs, and conventional disease-modifying antirheumatic drugs. Clinical trials evaluating the effect of these traditional and low-cost medications used to treat dactylitis should be encouraged

Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA): updated treatment recommendations for psoriatic arthritis 2021

Since the second version of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations were published in 2015, therapeutic options for psoriatic arthritis (PsA) have advanced considerably. This work reviews the literature since the previous recommendations (data published 2013–2020, including conference presentations between 2017 and 2020) and reports high-quality, evidence-based, domain-focused recommendations for medication selection in PsA developed by GRAPPA clinicians and patient research partners. The overarching principles for the management of adults with PsA were updated by consensus. Principles considering biosimilars and tapering of therapy were added, and the research agenda was revised. Literature searches covered treatments for the key domains of PsA: peripheral arthritis, axial disease, enthesitis, dactylitis, and skin and nail psoriasis; additional searches were performed for PsA-related conditions (uveitis and inflammatory bowel disease) and comorbidities. Individual subcommittees used a GRADE-informed approach, taking into account the quality of evidence for therapies, to generate recommendations for each of these domains, which were incorporated into an overall schema. Choice of therapy for an individual should ideally address all disease domains active in that patient, supporting shared decision-making. As safety issues often affect potential therapeutic choices, additional consideration was given to relevant comorbidities. These GRAPPA treatment recommendations provide up-to-date, evidence-based guidance on PsA management for clinicians and people with PsA

Determinants of patient-reported psoriatic arthritis impact of disease: an analysis of the association with gender in 458 patients from 14 countries

OBJECTIVES: Gender differences may modify symptoms, disease expression, and treatment effects. The objective was to evaluate the link between life impact and gender in psoriatic arthritis (PsA). METHODS: ReFlaP (NCT03119805) was a study in 14 countries of consecutive adult patients with definite PsA. Participants underwent comprehensive PsA assessment: Disease Activity in PSoriatic Arthritis (DAPSA), Minimal Disease Activity (MDA), and Psoriatic Arthritis Impact of Disease (PsAID). Disease activity was compared by gender using t-tests or Wilcoxon tests. The association of PsAID with gender was analyzed using hierarchical generalized linear models. RESULTS: Of 458 participants 50.2% were male, mean age (SD) 53.1 (12.6) years, PsA duration 11 (8.2) years, and 51.5% taking bDMARDs. Women versus men had worse Leeds enthesitis index: 0.8 (1.7) / 0.3 (0.9), pain [numerical rating scale 0-10 (NRS)]: 4.7 (2.7) / 3.5 (2.7), HAQ-DI: 0.9 (0.7) / 0.5 (0.6), fatigue NRS: 5.2 (3) / 3.3 (2.8), PsAID: 4.1 (2.4) / 2.8 (2.3), pandlt;0.001 for all, and were less frequently at treatment target (T2T): DAPSA (DAPSA cut-offs and#8804;4 remission, andgt;4 and and#8804;14 low disease activity): 16.9 (14.9) / 12.6 (16.6), MDA: 25.7% / 50.0%, pandlt;0.001 for all. High life impact (PsAIDand#8805;4) was associated with female gender [odds ratio (OR) 2.3], enthesitis (OR 1.34), tender joints (OR 1.10) pandlt;0.001 for all, and comorbidities (OR 1.22, p=0.002). CONCLUSIONS: High life impact was independently associated with female gender, enthesitis, comorbidities, and tender joints. At T2T, women vs men had higher life impact. Life impact needs to become part of PsA T2T strategies.</p
