Factors related to health-related quality of life in ankylosing spondylitis, overall and stratified by sex.

ABSTRACT: BACKGROUND:Ankylosing spondylitis (AS) begins early in life and often leads to reduced physical function, but less is known about the impacts it has on health-related quality of life (HRQoL). The aims of this study were to assess HRQoL using the Short Form-36 (SF-36) in a cohort of patients with AS compared with controls and to examine associations between SF-36 scores and spinal radiographic changes, physical function, disease activity and demographic data overall and stratified by sex. METHODS:A cohort of patients with AS from Western Sweden were assessed using the Modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) with spinal radiographs, clinical examination and questionnaires, including the Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Disease Activity Score-C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Patient Global (BASG) and SF-36. Each patient's SF-36 results were compared with those of five age-matched and sex-matched persons (n?=?1055) from the SF-36 Swedish normative population database. Associations between SF-36 physical component summary (PCS) and mental component summary (MCS) scores and disease-related and demographic factors were investigated using univariate and multivariable ogistic regression analyses with PCS and MCS below/above their respective median values as dependent variables. RESULTS:A total of 210 patients, age (median, IQR) 49.0 (21.2) years, symptom duration 24.0 (21.0) years, men 57.6% and HLAB27 87.1% were included. Patients with AS scored significantly lower (p?

Project description:IntroductionWe evaluated the three-year impact of adalimumab on patient-reported physical function and health-related quality-of-life (HRQOL) outcomes in patients with active ankylosing spondylitis (AS).MethodsThe Adalimumab Trial Evaluating Long-Term Efficacy and Safety in AS (ATLAS) is an ongoing five-year study that included an initial 24-week, randomized, placebo-controlled, double-blind period, followed by open-label extension treatment with adalimumab. Clinical and HRQOL data collected for up to three years from ATLAS were used for these analyses. Patients were randomized to receive adalimumab 40 mg or placebo by subcutaneous injection every other week. Physical function was assessed by the Bath AS Functional Index (BASFI), as well as by the Short Form 36 (SF-36) Health Survey Physical Component Summary (PCS) and Physical Function subscale scores. HRQOL was assessed using the AS Quality of Life (ASQOL) questionnaire. Disease activity was assessed by the Bath AS Disease Activity Index (BASDAI).ResultsOf 315 patients enrolled in ATLAS, 288 (91%) participated in an open-label adalimumab treatment extension and 82% provided three-year outcome data. During the 24-week double-blind phase, adalimumab-treated patients experienced significant improvement compared with placebo-treated patients in the BASDAI (P < 0.001), BASFI (P < 0.001), ASQOL (P < 0.001), and both the SF-36 PCS (P < 0.001) and Physical Function subscale (P < 0.001) scores, but not the SF-36 Mental Component Summary score (P = 0.181) and Mental Health subscale scores (P = 0.551). Mean changes from baseline through three years of adalimumab treatment were statistically significant for the BASDAI (change score: -3.9, P < 0.001), BASFI (change score: -29.6, P < 0.001), SF-36 PCS (change score: 11.6, P < 0.001), and Physical Function (change score: 23.3, P < 0.001). Comparable results were observed for the other SF-36 scores and for the ASQOL (all P < 0.001).ConclusionsAdalimumab significantly improved disease activity, patient-reported physical function, and HRQOL. These benefits were maintained over three years of treatment in patients with AS.

Project description:An increased prevalence of obstructive sleep apnoea (OSA) has been suggested in patients with ankylosing spondylitis (AS) in a few controlled studies. We aimed to study the prevalence of OSA compared to controls and to investigate if disease-related and non-disease-related factors were determinants of OSA in AS patients. One hundred and fifty-five patients with AS were included in the Backbone study, a cross-sectional study that investigates severity and comorbidities in AS. Controls were recruited from the Swedish CArdioPulmonary bioImage Study. To evaluate OSA, the participants were asked to undergo home sleep-monitoring during one night's sleep. For each AS patient 45-70 years old, four controls were matched for sex, age, weight, and height. OSA was defined as an apnoea-hypopnoea index (AHI) ≥ 5 events/hour. Sixty-three patients with AS were examined with home sleep-monitoring, and 179 controls were matched with 46 patients, 45-70 years. Twenty-two out of 46 (47.8%) patients with AS vs. 91/179 (50.8%) controls had OSA (AHI ≥ 5 events/hour), P = 0.72. No differences in the sleep measurements were noted in AS patients vs. controls. In logistic regression analysis adjusted for age and sex, higher age, higher BMI, and lesser chest expansion were associated with the presence of OSA in the 63 AS patients. In the current study, patients with AS did not have a higher prevalence of OSA compared to matched controls. AS patients with OSA had higher BMI, were older, and had lesser chest expansion because of more severe AS compared to patients without OSA. Key points • Patients with ankylosing spondylitis did not have a higher prevalence of obstructive sleep apnoea versus matched controls. • Patients with ankylosing spondylitis and obstructive sleep apnoea were older and had higher body mass index versus patients without obstructive sleep apnoea. • Patients with ankylosing spondylitis and obstructive sleep apnoea had lesser chest expansion versus patients without obstructive sleep apnoea.
