Ankylosing spondylitis disease activity score is related to NSAID use, especially in patients treated with TNF-α inhibitors.

ABSTRACT:

Background

Non-steroidal anti-inflammatory drugs (NSAIDs) are regarded as the cornerstone of conventional treatment for AS. However little is known about concomitant NSAID use during treatment (with TNF-α inhibitors) in daily clinical practice.

Methods and findings

Consecutive patients from the GLAS cohort were included. NSAID use and ASAS-NSAID index were evaluated at group level and at individual patient level during 52 weeks of follow-up. Analyses were stratified for treatment regimen. Generalized estimating equations (GEE) was used to evaluate NSAID use in relation to assessments of disease activity over time. In patients starting TNF-α inhibitors (n = 254), 79% used NSAIDs at baseline and this proportion decreased significantly to 38% at 52 weeks. ASAS-NSAID index also decreased significantly from median 65 to 0. In patients on conventional treatment (n = 139), 74% used NSAIDs at baseline with median ASAS-NSAID index of 50 and this remained stable during follow-up. At each follow-up visit, approximately half of the patients changed their type or dose of NSAIDs. GEE analysis over time showed that NSAID use was associated with AS disease activity score (p<0.05). This relation was more pronounced in patients treated with TNF-α inhibitors compared to conventional treatment (B = 0.825 vs. B = 0.250).

Conclusions

In this observational cohort of established AS patients, there was no difference in baseline NSAID use between patients with and without indication for TNF-α inhibitors. NSAID use decreased significantly after starting TNF-α inhibitors. During conventional treatment, NSAID use remained stable at group level. However, NSAID use changed frequently at individual patient level and was significantly associated with disease activity.

Project description:ObjectivesTo evaluate spinal radiographic damage over time and to explore the associations of radiographic progression with patient characteristics and clinical assessments including disease activity in ankylosing spondylitis (AS) patients treated with tumor necrosis factor-alpha (TNF-α) blocking therapy in daily clinical practice.MethodsConsecutive outpatients from the Groningen Leeuwarden AS (GLAS) cohort were included based on the availability of cervical and lumbar radiographs before start of TNF-α blocking therapy and after 2, 4, and/or 6 years of follow-up. Clinical data were assessed at the same time points. Radiographs were scored by two independent readers using the modified Stoke AS Spine Score (mSASSS). Spinal radiographic progression in relation to clinical assessments was analyzed using generalized estimating equations.Results176 AS patients were included, 58% had syndesmophytes at baseline. Median mSASSS increased significantly from 10.7 (IQR: 4.6-24.0) at baseline to 14.8 (IQR: 7.9-32.8) at 6 years. At the group level, spinal radiographic progression was linear with a mean progression rate of 1.3 mSASSS units per 2 years. Both spinal radiographic damage at baseline and radiographic progression were highly variable between AS patients. Male gender, older age, longer disease duration, higher BMI, longer smoking duration, high CRP, and high ASDAS were significantly associated with syndesmophytes at baseline. Significantly more radiographic progression was seen in patients with versus without syndesmophytes (2.0 vs. 0.5 mSASSS units per 2 years) and in patients >40 versus ≤40 years of age (1.8 vs. 0.7 mSASSS units per 2 years). No longitudinal associations between radiographic progression and clinical assessments were found.ConclusionsThis prospective longitudinal observational cohort study in daily clinical practice shows overall slow and linear spinal radiographic progression in AS patients treated with TNF-α blocking therapy. At the individual level, progression was highly variable. Patients with syndesmophytes at baseline showed a 4-fold higher radiographic progression rate than patients without syndesmophytes.

Project description:BackgroundBiologics and Janus kinase (JAK) inhibitors are commonly used to improve ankylosing spondylitis (AS) symptoms if conventional treatments are ineffective or unsuitable. This systematic review aimed to compare the therapeutic effects and safety of JAK inhibitors, tumor necrosis factor-alpha (TNF-α) inhibitors, and interleukin (IL) inhibitors in patients with AS.MethodsWe retrieved literature from various databases including Web of Science, Cochrane, Embase, PubMed, China National Knowledge Infrastructure, Weipu Journal Database, SinoMed, and WanFang Data up to February 1, 2023, and evaluated the quality of the included RCTs using the Cochrane risk-of-bias tool. R 4.1.3, STATA 15.1 were employed for network meta-analyses.ResultsWe identified 48 eligible articles including 8,937 patients. Ten articles were rated as "low risk", 5 as "high risk", and the others as "some concerns". In terms of efficacy, IL-17, IL-6, and JAK inhibitors were compared with TNF-α inhibitors in ASAS20 (RR =0.81, 95% CI: 0.66-0.98; RR =0.57, 95% CI: 0.35-0.95; RR =0.77, 95% CI: 0.60-0.99). IL-6 inhibitors were compared with TNF-α inhibitors in ASAS5/6 (RR =0.39, 95% CI: 0.16-0.98). IL-23, JAK inhibitors were compared with TNF-α inhibitors in BASDAI50 (RR =0.35, 95% CI: 0.20-0.60; RR =0.70, 95% CI: 0.49-0.98). IL-17 inhibitors were compared with IL-23 and IL-6 inhibitors in BASFI (MD =-1.05, 95% CI: -1.65--0.51; MD =-1.46, 95% CI: -2.02--0.97). In terms of safety, IL-6 inhibitors were compared with JAK, TNF-α inhibitors in AEs (RR =1.38, 95% CI: 1.06-1.88; RR =1.30, 95% CI: 1.01-1.70).ConclusionsTNF-α inhibitors are significantly superior to both IL and JAK inhibitors, and may be the preferable option to deal with the rapid progression of AS and severe functional limitations. IL-17 inhibitors may better improve the BASDAI50 response compared with JAK, IL-23, and TNF-α inhibitors. The efficacy and safety of IL-6 inhibitors are inferior to other types of drugs, indicating the low efficacy and high risk of IL-6 inhibitors.
