Enthesitis in a European registry-based cohort of patients with psoriatic arthritis treated with tumour necrosis factor inhibitors: clinical burden, patient-reported outcomes, and treatment response. Scand J Rheumatol 2024:1-11. [PMID: 38771017 DOI: 10.1080/03009742.2024.2336743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 03/27/2024] [Indexed: 05/22/2024]
Abstract
OBJECTIVE To explore the registration of enthesitis among biologic-naïve patients with psoriatic arthritis (PsA) initiating tumour necrosis factor inhibitor (TNFi) treatment across 12 European registries, compare the disease burden and patient-reported outcomes (PROs) between patients with and without enthesitis, and assess the enthesitis treatment response. METHOD Demographics, clinical characteristics, and PROs at first TNFi (TNFi-1) initiation (baseline) were assessed in patients with PsA, diagnosed by a rheumatologist, with versus without assessment of entheses and between those with versus without enthesitis. Enthesitis scores and resolution frequency were identified at follow-up. RESULTS Of 10 547 patients in the European Spondyloarthritis (EuroSpA) Research Collaboration Network initiating TNFi, 1357 underwent evaluation for enthesitis. Eight registries included a validated scoring system for enthesitis. At baseline, 874 patients underwent entheses assessment [Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) 485 patients, Spondyloarthritis Research Consortium of Canada (SPARCC) 389 patients]. Enthesitis was detected by MASES in 170/485 (35%, mean score ± sd 3.1 ± 2.4) and by SPARCC in 236/389 (61%, 4 ± 3.4). Achilles enthesitis was most frequent, by both MASES (unilateral/bilateral 28%/9%) and SPARCC (48%/18%). MASES/SPARCC baseline and follow-up scores for TNFi-1 were available for 100/105 patients. Of these, 63 patients (63%) (MASES) and 46 (43.8%) (SPARCC) achieved resolution of enthesitis. The site-specific enthesitis resolution was overall lower at SPARCC sites (peripheral; 63-80%) than at MASES sites (mainly axial; 82-100%) following TNFi-1. Disease activity and PROs were worse in patients with versus without enthesitis. CONCLUSION Entheseal assessments are only registered in a minority of patients with PsA in routine care. When assessed, enthesitis was common, and a substantial proportion demonstrated resolution following treatment with TNFi-1.

Association between enthesitis/dactylitis resolution and patient-reported outcomes in guselkumab-treated patients with psoriatic arthritis. Clin Rheumatol 2024; 43:1591-1604. [PMID: 38472528 PMCID: PMC11018666 DOI: 10.1007/s10067-024-06921-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 02/21/2024] [Accepted: 02/26/2024] [Indexed: 03/14/2024]
Abstract
OBJECTIVES To evaluate the association between enthesitis resolution (ER) and dactylitis resolution (DR) and meaningful improvements in patient-reported outcomes (PROs) among biologic-naïve patients with PsA receiving guselkumab in the DISCOVER-2 study. METHODS Enthesitis and dactylitis, characteristic lesions of PsA, were evaluated by independent assessors using the Leeds Enthesitis Index (range, 0-6) and Dactylitis Severity Score (range, 0-60). Proportions of patients with ER or DR (score = 0) among those with score > 0 at baseline were determined at weeks 24, 52, and 100. PROs included: fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue]), pain (0-100 visual analog scale), physical function (Health Assessment Questionnaire-Disability Index [HAQ-DI]), and health-related quality of life (36-item Short-Form Health Survey physical/mental component summary [SF-36 PCS/MCS]). Meaningful responses were defined as: improvements of ≥ 4 for FACIT-Fatigue, ≥ 0.35 for HAQ-DI, and ≥ 5 for SF-36 PCS/MCS and absolute scores of ≤ 15 for minimal pain and ≤ 0.5 for normalized HAQ-DI. Associations between ER/DR status and PRO response status were tested using a Chi-square test. RESULTS Guselkumab-treated patients with ER were more likely than those without ER to achieve minimal pain (p < 0.001), normalized HAQ-DI (p < 0.001), and PCS response (p < 0.05) at weeks 24, 52, and 100. Patients with DR were more likely than those without DR to achieve FACIT-Fatigue response at week 24 and week 52 (both p ≤ 0.01) and minimal pain at week 24 and normalized HAQ-DI at week 52 (both p ≤ 0.03). CONCLUSION In biologic-naïve patients with active PsA treated with guselkumab, achieving ER or DR was associated with durable improvements in selected PROs, including those of high importance to patients. TRIAL REGISTRATION ClinicalTrials.gov ( https://clinicaltrials.gov ) NCT03158285; Registered: May 16, 2017. Key Points • At week 100, 65% and 76% of guselkumab-treated patients achieved enthesitis and dactylitis resolution (ER/DR). • Achieving ER was associated with achieving DR and vice versa through the end of study. • Achieving ER or DR was associated with durable and meaningful improvements in selected patient-reported outcomes.

Enthesitis in patients with psoriatic arthritis treated with secukinumab or adalimumab: a post hoc analysis of the EXCEED study. Rheumatology (Oxford) 2024; 63:41-49. [PMID: 37097894 PMCID: PMC10765155 DOI: 10.1093/rheumatology/kead181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 03/15/2023] [Accepted: 03/19/2023] [Indexed: 04/26/2023] Open
Abstract
OBJECTIVES To evaluate enthesitis treatment response, including time to resolution and data from multiple enthesitis instruments, in patients with PsA treated with secukinumab or adalimumab for 52 weeks. METHODS In this post hoc analysis of the EXCEED study, patients receiving secukinumab 300 mg or adalimumab 40 mg per the label were grouped by presence or absence of baseline enthesitis based on the Leeds Enthesitis Index (LEI) and the Spondyloarthritis Research Consortium of Canada Enthesitis Index (SPARCC). Efficacy was assessed according to several enthesitis-related instruments using non-responder imputation for the achievement of enthesitis resolution (LEI/SPARCC = 0), Kaplan-Meier analysis for time to resolution, and as-observed data for other outcomes. RESULTS Enthesitis was present at baseline in 498 of 851 patients (58.5%) as assessed by LEI and in 632 of 853 patients (74.1%) as assessed by SPARCC. Patients with baseline enthesitis generally presented with greater disease activity. Similar proportions of patients receiving secukinumab or adalimumab achieved resolution of LEI and SPARCC at weeks 24 (secukinumab: LEI/SPARCC, 49.6%/45.8%; adalimumab: LEI/SPARCC, 43.6%/43.5%) and 52 (secukinumab: LEI/SPARCC, 60.7%/53.2%; adalimumab: LEI/SPARCC, 55.3%/51.4%), with comparable mean time to enthesitis resolution. Improvements were similar for both drugs at individual enthesitis sites. Resolution of enthesitis with secukinumab or adalimumab was associated with improvements in quality of life at week 52. CONCLUSION Secukinumab and adalimumab showed similar efficacy, including time to resolution, with respect to resolution of enthesitis. Inhibition of IL-17 with secukinumab reduced clinical enthesitis similarly to TNF-α inhibition. TRIAL REGISTRATION ClinicalTrials.gov, NCT02745080.

Efficacy of tofacitinib on enthesitis in patients with active psoriatic arthritis: analysis of pooled data from two phase 3 studies. Arthritis Res Ther 2023; 25:153. [PMID: 37608391 PMCID: PMC10464128 DOI: 10.1186/s13075-023-03108-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 07/05/2023] [Indexed: 08/24/2023] Open
Abstract
BACKGROUND Tofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA). This post hoc analysis assessed tofacitinib efficacy on enthesitis by baseline location and severity, and impact on disease activity and patient-reported outcomes (PROs), in patients with PsA. METHODS Data were pooled from two phase 3 studies (NCT01877668/NCT01882439) in patients with PsA receiving tofacitinib 5 or 10 mg twice daily to month (M)6 or placebo to M3. Endpoints were: change from baseline in Leeds Enthesitis Index (LEI) or Spondyloarthritis Research Consortium of Canada Enthesitis Index (SPARCC); proportions of patients with enthesitis, relapsed enthesitis after resolution, de novo enthesitis, low disease activity (LDA) or remission (minimal disease activity/very low disease activity; Psoriatic Arthritis Disease Activity Score; Disease Activity Index for Psoriatic Arthritis, and Composite Psoriatic Disease Activity in Psoriatic Arthritis); and PROs (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F] total and arthritis pain Visual Analog Scale scores). Descriptive statistics were generated by visit and treatment. Change from baseline in PROs was evaluated by multivariate linear regression. RESULTS Seven hundred ten patients from two studies were included: 479 had LEI > 0; 545 had SPARCC > 0; and 136 had LEI = 0 and SPARCC = 0 at baseline. At baseline, among patients with LEI > 0 or SPARCC > 0, mean LEI and SPARCC across treatments and enthesitis locations/severities ranged from 1.0-4.4 and 1.3-9.4, respectively. Across several baseline enthesitis locations/severities, changes from baseline in LEI and SPARCC up to M3 were greater with tofacitinib (-2.0-0.4 and -3.5-0.2) vs placebo (-0.9-0.4 and -1.5-1.1). Enthesitis at M6 was more common in patients with greater baseline enthesitis severity. At M6, ≤ 40% of patients with baseline LEI > 0 or SPARCC > 0 whose enthesitis had resolved by M1/M3 experienced a relapse, and < 14% of patients with baseline LEI = 0 and SPARCC = 0 had de novo enthesitis. LDA/remission rates generally increased with tofacitinib over time. Baseline LEI location was significantly associated with change from baseline in arthritis pain score, while baseline SPARCC severity was significantly associated with change from baseline in FACIT-F total and arthritis pain scores. CONCLUSION Tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity. TRIAL REGISTRATION NCT01877668;NCT01882439.

Abstract
OBJECTIVES To determine the individual impact of key manifestations of psoriatic arthritis (PsA) on quality of life (QoL), physical function, and work disability. METHODS Data from the Adelphi 2018 PsA Disease-Specific Programme, a multinational, cross-sectional study of PsA patients, were used. PsA manifestations included peripheral arthritis (number of joints affected), psoriasis (body surface area [BSA]), axial involvement (inflammatory back pain [IBP] and sacroiliitis) enthesitis, and dactylitis. General, and disease-specific QoL, physical function, and work disability were measured with EQ-5D-5L, PsAID-12, HAQ-DI, and WPAI, respectively. Multivariate regression adjusting for potential confounders evaluated the independent effect of PsA manifestations on each outcome. RESULTS Among the 2222 PsA patients analysed, 77.0% had active psoriasis and 64.4% had peripheral arthritis; 5.9%, 6.8%, 10.2%, and 3.6% had enthesitis, dactylitis, IBP, or sacroiliitis, respectively. Mean EQ VAS scores were significantly poorer in patients with vs. without enthesitis (59.9 vs. 75.6), dactylitis (63.6 vs. 75.4), and with greater peripheral joint involvement (none: 82.5; 1-2 affected joints: 74.1; 3-6 joints: 74.2; >6 joints: 65.0). Significantly worse mean PsAID-12 scores were associated with vs. without enthesitis (4.39 vs. 2.34) or dactylitis (4.30 vs. 2.32), and with greater peripheral joint involvement (none: 1.21; 1-2 joints: 2.36; 3-6 joints: 2.74; >6 joints: 3.92), and BSA (none: 1.49; >3-10%: 2.96; >10%: 3.43). Similar patterns were observed with HAQ-DI and WPAI scores. CONCLUSION Most PsA manifestations were independently associated with worse general, and PsA-specific QoL, physical function, and work disability, highlighting the need for treatments targeting the full spectrum of PsA symptoms to lower the burden of disease.

Abstract
Abstract
Background
Psoriatic arthritis (PsA) which affects 6–42% of psoriasis patients is the most common extra-cutaneous manifestation of the psoriasis disease. Enthesitis may be considered as a sign of increased disease burden due to its association with several clinical aspects. Therefore, the aim of the study was to investigate the effect of clinical enthesitis on quality of life and work productivity in PsA patients.
Results
Enthesitis was detected in 50% of patients. There was statistically significant difference between the studied groups as regard disease activity index for psoriatic arthritis (DAPSA) score, psoriatic arthritis impact of the disease 12 (PsAID-12), Health Assessment Questionnaire disability index (HAQ-DI), and Spondyloarthritis Research Consortium of Canada index (SPARCC) with higher mean score in patients with enthesitis. The majority of patients with enthesitis had a higher percentage of impairment in daily activities (95.5%) than those without enthesitis (38.6%), as well as a statistically significant positive correlation between SPARCC index and both work absenteeism and work productivity loss. Furthermore, enthesitis in both the upper and lower sites was related with worse quality of life (36.4%) and higher work impairment (45.5%) compared to patients with enthesitis in either the upper or lower sites alone.
Conclusion
Enthesitis was a frequent complaint among PsA patients. PsA patients with enthesitis had a significant disease burden regardless of enthesitis location, and patients with enthesitis in both the upper and lower sites have a worse quality of life and a higher work impairment.
