Objective To assess current evidence for effectiveness of sequential lines of biologic and targeted small-molecule disease-modifying anti-rheumatic drugs (b/tsDMARDs) when used beyond first-line for psoriatic arthritis (PsA). Methods A systematic search of the literature (Medline, Embase, bibliographic searches) was undertaken (October and December 2022) to find studies meeting the criteria of assessing effectiveness of b/tsDMARDs beyond first-line in adults with PsA (PROSPERO CRD42022365298). Risk of bias assessment was undertaken (ROBINS-I/Cochrane RoB2). Results Of 2666 abstracts identified and following a full text review of 177 psoriatic disease studies, 12 manuscripts and two abstracts were eligible. Of the 12 manuscripts, 11 were observational and one was a sub-analysis of a RCT (n  = 16 081: average age 49.5 years, female 53.3%). Two abstracts (n  = 7186) were included. All studies comparing first- and second-line (three studies) found a reduced response in second-line. On average, DAPSA remission (most reported outcome, eight studies) was achieved in 26%, 19% and 10% first-, second- and third-line TNFi, and 22%, 13% and 11% first-, second- and third-line other bDMARDs, respectively. Responses varied to third-line bDMARDs; four studies found comparable second- and third-line responses, five studies found diminishing responses in sequential lines. Conclusion Predominantly observational studies, inherently at high risk of bias, indicate bDMARDs can be effective to third-line in PsA, but that response is reduced after first line. There is very limited data for more advanced lines of b/tsDMARD. Prospective studies are required to better understand clinical response to advanced lines of treatment in PsA. [ABSTRACT FROM AUTHOR]

Objectives The objective of this study was to compare the performance of three PsA screening questionnaires in a primary care psoriasis surveillance study. Methods Participants with psoriasis, and not known to have PsA, were identified from general practice databases and invited to attend a secondary care centre for a clinical assessment. The three patient-completed screening questionnaires (PEST, CONTEST and CONTESTjt) were administered, along with other patient-reported measures, and a clinical examination of skin and joints was performed. Participants who demonstrated signs of inflammatory arthritis suggestive of PsA were referred, via their GP, for a further assessment in a secondary care rheumatology clinic. Results A total of 791 participants attended the screening visit, and 165 participants were judged to have signs and symptoms of inflammatory arthritis, of which 150 were referred for assessment. Of these, 126 were seen and 48 were diagnosed with PsA. The results for each questionnaire were as follows: PEST: sensitivity 0.625 (95% CI 0.482, 0.749), specificity 0.757 (0.724, 0.787); CONTEST: sensitivity 0.604 (0.461, 0.731), specificity 0.768 (0.736, 0.798); and CONTESTjt: sensitivity 0.542 (0.401, 0.676), specificity 0.834 (0.805, 0.859). CONTESTjt demonstrated marginally superior specificity to PEST, though the area under the ROC curve was similar for all three instruments. Conclusion Minimal differences between the three screening questionnaires were found in this study, and no preferred questionnaire is indicated by these results. The choice of which instrument to choose will depend on other factors, such as simplicity and low patient burden. [ABSTRACT FROM AUTHOR]

Objectives Evaluate effects of long-term bimekizumab treatment on patient-reported outcome (PRO) measures, symptoms and the impact of PsA on patients. Methods Patients with active PsA were enrolled into BE ACTIVE, a 48-week randomised controlled trial (NCT02969525). After Week 48, patients could enter a 104-week open-label extension (NCT03347110), receiving bimekizumab 160 mg every four weeks. PRO measures assessed included arthritis pain visual analogue scale (VAS), PsA Impact of Disease (PsAID)-9, 36-Item Short Form Survey (SF-36) and HAQ-Disability Index (HAQ-DI). Results were analysed as mean (S.E.M.) changes from baseline (CfB) from Week 0 to the end of the open-label extension (3 years) and as percentage of patients reaching patient-acceptable symptom state (PASS) for global impact (PsAID-9 total score ≤4) and normal function (HAQ-DI total score <0.5). Non-responder imputation was applied to missing binary outcomes. Results In 206 patients (mean age 49.3 years, 51.0% male), completion rate was high; 161 (78.2%) patients completed Week 152. Bimekizumab treatment was associated with long-term sustained improvements in pain [arthritis pain VAS CfB; Week 48: −29.9 (1.9); Week 152: −32.0 (1.9)] and fatigue [PsAID-9 fatigue CfB; −2.4 (0.2); −2.7 (0.2)]. High percentages of patients achieved acceptable symptom state (PsAID-9 PASS: 75.2%; 65.0%) and normalised function (HAQ-DI <0.5: 49.0%; 46.1%). Improvements in patient global assessment and SF-36 Physical Component Summary were also sustained. Conclusions Bimekizumab treatment was associated with long-term sustained improvements in pain and fatigue, reducing overall impact of PsA on patients. Physical function and quality of life improved up to 3 years. Trial registration ClinicalTrials.gov, https://clinicaltrials.gov , NCT02969525, NCT03347110. [ABSTRACT FROM AUTHOR]

The article discusses the 2022 British Society for Rheumatology (BSR) guidelines for the use of biologic and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) in the treatment of patients with psoriatic arthritis (PsA). Topics explored include the clinical characteristics and prevalence of PsA, the patient outcomes associated with treat-to-target PsA management, and the DMARDs treatment and prescribing strategies that need to be considered by clinicians.

Objectives The aim of this study was to explore the use of Bayesian networks (BNs) to understand the relationships between musculoskeletal symptoms and the development of PsA in people with psoriasis. Methods Incident cases of psoriasis were identified for 1998 to 2015 from the UK Clinical Research Practice Datalink. Musculoskeletal symptoms (identified by Medcodes) were concatenated into primary groups, each made up of several subgroups. Baseline demographics for gender, age, BMI, psoriasis severity, alcohol use and smoking status were also extracted. Several BN structures were composed using a combination of expert knowledge and data-oriented modelling based on: (i) primary musculoskeletal symptom groups; (ii) musculoskeletal symptom subgroups and (iii) demographic variables. Predictive ability of the networks using the area under the receiver operating characteristic curve was calculated. Results Over one million musculoskeletal symptoms were extracted for the 90 189 incident cases of psoriasis identified, of which 1409 developed PsA. The BN analysis yielded direct relationships between gender, BMI, arthralgia, finger pain, fatigue, hand pain, hip pain, knee pain, swelling, back pain, myalgia and PsA. The best BN, achieved by using the more site-specific musculoskeletal symptom subgroups, was 76% accurate in predicting the development of PsA in a test set and had an area under the receiver operating characteristic curve of 0.73 (95% CI: 0.70, 0.75). Conclusion The presented BN model may be a useful method to identify clusters of symptoms that predict the development of PsA with reasonable accuracy. Using a BN approach, we have shown that there are several symptoms which are predecessors of PsA, including fatigue, specific types of pain and swelling. [ABSTRACT FROM AUTHOR]

The article reviews the use of systemic glucocorticoids in psoriatic arthrtitis (PsA) and the occurrence of flares in PsA and psoriasis as of 2022. Topics discussed include the evidence that local and systemic glucocorticoids are effective in PsA, and recommendations of current PsA treatment guidelines. Also noted are the practice changing implications of a systemic literature review.

The aim of this guideline is to provide an update on evidence-based recommendations for treatment of adult patients with PsA. The previous BSR guidelines for PsA were published in 2012 and since that time, there have been many new advanced therapies licensed for PsA. This update will provide practical guidance for clinicians on the optimal selection of advanced therapies taking into account different domains of PsA (arthritis, enthesitis, dactylitis, axial disease and psoriasis) and key associated comorbidities. It will also update guidance on treatment strategy including the use of a treat-to-target approach. The guideline will be developed using the methods and processes outlined in Creating Clinical Guidelines: Our Protocol. (1) This development process to produce guidance, advice and recommendations for practice has National Institute for Health and Care Excellence (NICE) accreditation. [ABSTRACT FROM AUTHOR]

Objective To examine the effects of filgotinib, an oral, selective Janus kinase 1 inhibitor, on health-related quality of life (HRQoL) using the Psoriatic Arthritis Impact of Disease (PsAID)9 questionnaire in active PsA. Methods Patients were randomized 1 : 1 to filgotinib 200 mg or placebo once daily for 16 weeks in EQUATOR, a multicentre, double-blind, phase 2 randomized controlled trial. HRQoL was assessed with PsAID9 at Weeks 4 and 16. Change from baseline in total and individual domain scores, plus the proportions of patients achieving minimal clinically important improvement (MCII; ⩾3 points) and patient-accepted symptom status (PASS; score <4), were evaluated. Correlation with the 36-item short-form health survey (SF-36) was investigated. Results One hundred and thirty-one patients were randomized to filgotinib or placebo. Filgotinib effects on PsAID9 were observed from Week 4. At Week 16, mean (s. d.) change from baseline in PsAID9 was –2.3 (1.8) and –0.8 (2.2) for filgotinib and placebo, respectively (least-squares mean of group difference –1.48 [95% CI –2.12, –0.84], P < 0.0001), with significant improvements in all domains vs placebo. Significantly more patients on filgotinib achieved MCII (group difference 25.4% [95% CI 8.92, 39.99], P = 0.0022) and PASS (group difference 29.6% [95% CI 10.65, 45.60], P = 0.0018) at Week 16 vs placebo. Similar improvements in SF-36 were observed, with moderate to strong negative correlation between PsAID9 and SF-36. Conclusion Filgotinib significantly improved HRQoL vs placebo in patients with active PsA, as measured by PsAID9. To our knowledge, EQUATOR is the first randomized controlled trial to evaluate PsAID9. Trial registration ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show , NCT03101670. [ABSTRACT FROM AUTHOR]
