Patient-reported outcomes in axial spondyloarthritis and psoriatic arthritis patients treated with secukinumab for 24 months in daily clinical practice.

OBJECTIVES: In patients with axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA) initiating secukinumab, we aimed to assess and compare the proportion of patients achieving 6-, 12- and 24-month patient-reported outcomes (PRO) remission and the 24-month retention rates. PATIENTS AND METHODS: Patients with axSpA or PsA from 16 European registries, who initiated secukinumab in routine care were included. PRO remission rates were defined as pain, fatigue, Patient Global Assessment (PGA) ≤2 (Numeric Rating Scale (NRS) 0-10) and Health Assessment Questionnaire (HAQ) ≤0.5, for both axSpA and PsA, and were calculated as crude values and adjusted for drug adherence (LUNDEX). Comparisons of axSpA and PsA remission rates were performed using logistic regression analyses (unadjusted and adjusted for multiple confounders). Kaplan-Meier plots with log-rank test and Cox regression analyses were conducted to assess and compare secukinumab retention rates. RESULTS: We included 3087 axSpA and 3246 PsA patients initiating secukinumab. Crude pain, fatigue, PGA and HAQ remission rates were higher in axSpA than in PsA patients, whereas LUNDEX-adjusted remission rates were similar. No differences were found between the patient groups after adjustment for confounders. The 24-month retention rates were similar in axSpA vs. PsA in fully adjusted analyses (HR [95 %CI] = 0.92 [0.84-1.02]). CONCLUSION: In this large European real-world study of axSpA and PsA patients treated with secukinumab, we demonstrate for the first time a comparable effectiveness in PRO remission and treatment retention rates between these two conditions when adjusted for confounders.

Predictors of DAPSA28 remission in patients with psoriatic arthritis initiating a first TNF inhibitor: results from 13 European registries.

OBJECTIVES: In bio-naïve patients with PsA initiating a TNF inhibitor (TNFi), we aimed to identify baseline predictors of Disease Activity index for PsA in 28 joints (DAPSA28) remission (primary objective) and DAPSA28 moderate response at 6 months, as well as drug retention at 12 months across 13 European registries. METHODS: Baseline demographic and clinical characteristics were retrieved and the three outcomes investigated per registry and in pooled data, using logistic regression analyses on multiply imputed data. In the pooled cohort, selected predictors that were either consistently positive or negative across all three outcomes were defined as common predictors. RESULTS: In the pooled cohort (n = 13 369), 6-month proportions of remission, moderate response and 12-month drug retention were 25%, 34% and 63% in patients with available data (n = 6954, n = 5275 and n = 13 369, respectively). Five common baseline predictors of remission, moderate response and 12-month drug retention were identified across all three outcomes. The odds ratios (95% CIs) for DAPSA28 remission were: age, per year: 0.97 (0.96-0.98); disease duration, years (<2 years as reference): 2-3 years: 1.20 (0.89-1.60), 4-9 years: 1.42 (1.09-1.84), ≥10 years: 1.66 (1.26-2.20); men vs women: 1.85 (1.54-2.23); CRP of >10 vs ≤10 mg/l: 1.52 (1.22-1.89) and 1 mm increase in patient fatigue score: 0.99 (0.98-0.99). CONCLUSION: Baseline predictors of remission, response and adherence to TNFi therapy were identified, of which five were common for all three outcomes, indicating that the predictors emerging from our pooled cohort may be considered generalizable from country level to disease level.

Commonalities and differences in set-up and data collection across European spondyloarthritis registries - results from the EuroSpA collaboration.

BACKGROUND: In European axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) clinical registries, we aimed to investigate commonalities and differences in (1) set-up, clinical data collection; (2) data availability and completeness; and (3) wording, recall period, and scale used for selected patient-reported outcome measures (PROMs). METHODS: Data was obtained as part of the EuroSpA Research Collaboration Network and consisted of (1) an online survey and follow-up interview, (2) upload of real-world data, and (3) selected PROMs included in the online survey. RESULTS: Fifteen registries participated, contributing 33,948 patients (axSpA: 21,330 (63%), PsA: 12,618 (37%)). The reported coverage of eligible patients ranged from 0.5 to 100%. Information on age, sex, biological/targeted synthetic disease-modifying anti-rheumatic drug treatment, disease duration, and C-reactive protein was available in all registries with data completeness between 85% and 100%. All PROMs (Bath Ankylosing Spondylitis Disease Activity and Functional Indices, Health Assessment Questionnaire, and patient global, pain and fatigue assessments) were more complete after 2015 (68-86%) compared to prior (50-79%). Patient global, pain and fatigue assessments showed heterogeneity between registries in terms of wording, recall periods, and scale. CONCLUSION: Important heterogeneity in registry design and data collection across fifteen European axSpA and PsA registries was observed. Several core measures were widely available, and an increase in data completeness of PROMs in recent years was identified. This study might serve as a basis for examining how differences in data collection across registries may impact the results of collaborative research in the future.

Differences and similarities between the EULAR/ASAS-EULAR and national recommendations for treatment of patients with psoriatic arthritis and axial spondyloarthritis across Europe.

This is the first report comparing EULAR and national treatment recommendations for PsA patients across Europe, and the first this decade to compare ASAS-EULAR and national treatment recommendations in axSpA patients. An electronic survey was completed from October 2021-April 2022 by rheumatologists in 15 European countries. One and four countries followed all EULAR and ASAS-EULAR recommendations, respectively. Five countries had no national treatment recommendations for PsA and/or axSpA, but followed other regulations. In several countries, national treatment recommendations predated the most recent EULAR/ASAS-EULAR recommendations. Entry criteria for starting biologic/targeted synthetic disease-modifying anti-rheumatic drugs varied considerably. In several countries, for PsA patients with significant skin involvement, interleukin-17 inhibitors were not given preference. The positioning of Janus Kinase inhibitors differed and Phosphodiesterase-4 inhibitors were not in use/reimbursed in most countries. This study may motivate European countries to update their national treatment recommendations, to align them better with the latest international recommendations.

Predictors of ASDAS-CRP inactive disease in axial spondyloarthritis during treatment with TNF-inhibitors: Data from the EuroSpA collaboration.

OBJECTIVES: In patients with axial spondyloarthritis (axSpA) initiating their first tumor necrosis factor alpha-inhibitor (TNFi), we aimed to identify common baseline predictors of Ankylosing Spondylitis Disease Activity Score (ASDAS-CRP) inactive disease (primary objective) and clinically important improvement (CII) at 6 months, and drug retention at 12-months across 15 European registries. METHODS: Baseline demographic and clinical characteristics were collected. Outcomes were investigated per registry and in pooled data using logistic regression analyses on multiply imputed data. RESULTS: The consistency of baseline predictors in individual registries justified pooling the data. In the pooled dataset (n = 21,196), the 6-month rates for ASDAS inactive disease and ASDAS CII were 26% and 51%, and the 12-month drug retention rate 65% in patients with available data (n = 9,845, n = 6,948 and n = 21,196, respectively). Nine common baseline predictors of ASDAS inactive disease, ASDAS CII and 12-month drug retention were identified, and the odds ratios (95%-confidence interval) for ASDAS inactive disease were: age, per year: 0.97 (0.97-0.98), men vs. women: 1.88 (1.60-2.22), current vs. non-smoking: 0.76 (0.63-0.91), HLA-B27 positive vs. negative: 1.51 (1.20-1.91), TNF start year 2015-2018 vs. 2009-2014: 1.24 (1.06-1.45), CRP>10 vs. ≤10 mg/l: 1.49 (1.25-1.77), one unit increase in health assessment questionnaire (HAQ): 0.77 (0.58-1.03), one-millimeter (mm) increase in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) fatigue and spinal pain: 0.99 (0.99-1.00) and 0.99 (0.99-1.99), respectively CONCLUSION: Common baseline predictors of treatment response and adherence to TNFi could be identified across data from 15 European registries, indicating that they may be universal across different axSpA populations.

European bio-naïve spondyloarthritis patients initiating TNF inhibitor: time trends in baseline characteristics, treatment retention and response.

OBJECTIVES: To investigate time trends in baseline characteristics and retention, remission and response rates in bio-naïve axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) patients initiating TNF inhibitor (TNFi) treatment. METHODS: Prospectively collected data on bio-naïve axSpA and PsA patients from routine care in 15 European countries were pooled. Three cohorts were defined according to year of TNFi initiation: A (1999-2008), B (2009-2014) and C (2015-2018). Retention, remission and response rates were assessed at 6, 12 and 24 months. RESULTS: In total, 27 149 axSpA and 17 446 PsA patients were included. Cohort A patients had longer disease duration compared with B and C. In axSpA, cohort A had the largest proportion of male and HLA-B27 positive patients. In PsA, baseline disease activity was highest in cohort A. Retention rates in axSpA/PsA were highest in cohort A and differed only slightly between B and C. For all cohorts, disease activity decreased markedly from 0 to 6 months. In axSpA, disease activity at 24 months was highest in cohort A, where also remission and response rates were lowest. In PsA, remission rates at 6 and 12 months tended to be lowest in cohort A. Response rates were at all time points comparable across cohorts, and less between-cohort disease activity differences were seen at 24 months. CONCLUSION: Our findings indicate that over the past decades, clinicians have implemented more aggressive treatment strategies in spondyloarthritis. This was illustrated by shorter disease duration at treatment initiation, decreased retention rates and higher remission rates during recent years.

Smoking cessation advice by rheumatologists: results of an international survey.

OBJECTIVE: The aim of this study was to understand practices regarding smoking cessation among rheumatologists for patients with inflammatory rheumatic diseases. METHODS: A survey was sent to the rheumatologists participating in the multinational Quantitative Standard Monitoring of Patients with Rheumatoid Arthritis (QUEST-RA) group. The survey inquired about the clinical practice characteristics and practices regarding smoking cessation (proportion of smokers with inflammatory rheumatic diseases given smoking cessation advice, specific protocols and written advice material, availability of dedicated smoking cessation clinic). RESULTS: Rheumatologists from 44 departments in 25 countries (16 European) completed the survey. The survey involved 395 rheumatologists, of whom 25 (6.3%) were smokers, and 199 nurses for patient education, of whom 44 (22.1%) were smokers. Eight departments (18.1 %) had a specific protocol for smoking cessation; 255 (64.5%) rheumatologists reported giving smoking cessation advice to all or almost all smokers with inflammatory diseases. In a regression model, early arthritis clinics (P = 0.01) and high gross domestic product countries (P = 0.001) were both independently associated with advice by the rheumatologist. Nurse gives advice to most patients in 11 of the 36 (30.5%) departments with nurses for patient education. CONCLUSION: Advice for smoking cessation within rheumatology departments is not homogeneous. In half of the departments, most doctors give advice to quit smoking to all or almost all patients with inflammatory diseases. However, only one in five departments have a specific protocol for smoking cessation. Our data highlight the need to improve awareness of the importance of and better practice implementation of smoking cessation advice for inflammatory rheumatic disease patients.

Health-related quality of life in patients with common rheumatic diseases referred to a university clinic.

The aim of the present study was to assess the health-related quality of life (HRQoL) in patients with common rheumatic diseases referred to a rheumatology clinic and to compare it to the HRQoL of the general population. All patients with a new referral to the Department of Rheumatology of the Helsinki University Central Hospital were asked to participate in the study during the period from May 2002 to April 2003. A total of 295 patients with various rheumatic diseases were included in the analysis: 99 patients with rheumatoid arthritis (RA), 47 with arthralgia and fibromyalgia, 43 with other chronic arthritis (spondyloarthritis, psoriatic arthritis, enteropathic arthritis), 44 with osteoarthritis (OA), 22 with active reactive arthritis (ReA), 17 with systemic rheumatic diseases, 9 adults with juvenile idiopathic arthritis (JIA) and 14 with other diagnoses. HRQoL was measured by a disease specific instrument, the Stanford health assessment questionnaire (HAQ) and by a generic instrument, 15D. The mean baseline 15D score of the 295 included patients (0.822, SD 0.114) was significantly lower than of the general population (0.903, SD 0.098). Patients with OA and chronic arthritis reported the poorest HRQoL scores (both 0.810 on a 0-1 scale). In patients with RA and ReA the 15D score improved in a statistically significant and clinically important manner during the 8-month follow-up. Discomfort and symptoms caused by the disease were alleviated in a statistically significant manner in patients with RA as well as in those with arthralgia and fibromyalgia, chronic arthritis, ReA and systemic rheumatic diseases. HAQ score improved significantly in patients with RA, arthralgia and fibromyalgia, and ReA. The HRQoL of patients with common rheumatic diseases at referral to rheumatology clinic is significantly lower than the HRQoL of age-standardized general population. The most affected patients are those with OA, chronic arthritis and RA. A significant improvement in HRQoL with conventional interventions was achieved in patients with RA and ReA.

Clinical impact of switching from infliximab to etanercept in patients with rheumatoid arthritis.

We assessed the disease activity in patients with rheumatoid arthritis (RA) after switching from infliximab to etanercept according to the reason of infliximab discontinuation. At Helsinki University Central Hospital during the period 1999 to 2003, 49 patients with RA were switched from infliximab to etanercept. The reasons for infliximab discontinuation were: 42% for failure to respond by >American College of Rheumatology 50% criteria; 12% for adverse events; 46% responded to infliximab and were switched for non-medical reasons. Clinical outcome after the switch was compared between the groups according to the reason of infliximab discontinuation. Disease activity was measured with the 28-joint count Disease Activity Score (DAS28). In patients in the non-medical reasons group, the disease activity was suppressed effectively both during infliximab and etanercept. Furthermore, the one-year drug survival of etanercept in this group was the highest of 77% (95% confidence interval (CI), 62 to 97) among the three groups. In patients in the infliximab failure and adverse event groups, DAS28 values improved significantly during etanercept therapy. The 1-year drug survival of etanercept was 43% (95% CI, 26 to 70) and 50% (95% CI, 33 to 100), respectively. For RA patients who discontinued taking infliximab because of non-medical reasons experienced similar treatment efficacy during both biological agents. The treatment with etanercept provided sufficient disease control also for patients with infliximab failure or adverse event. Therefore, etanercept can be suggested when infliximab has failed or discontinued for other reasons.
