- Abstract
Objective. Chronic pain and progressive loss of physical function with AS may adversely affect health-related quality of life (HRQoL). The objective of this study was to assess the 5-year data regarding spinal mobility, physical function and HRQoL in patients with AS who participated in the Adalimumab Trial Evaluating Long-term Efficacy and Safety for AS (ATLAS) study. Methods. Patients received blinded adalimumab 40mg or placebo every other week for 24 weeks, then open-label adalimumab for up to 5 years. Spinal mobility was evaluated using linear BASMI (BASMIlin). BASDAI, total back pain, CRP, BASFI, Short Form-36 and AS quality of life (ASQoL) were also assessed. Correlations between BASMIlin and clinical, functional and ASQoL outcomes after 12 weeks and after 5 years of adalimumab exposure were evaluated using Spearman's rank correlation. Associations were further analysed using multivariate regression. Results. Three hundred and eleven patients received 51 dose of adalimumab; 125 of the 208 patients originally randomized to adalimumab received treatment for 5 years. Improvements in BASMIlin were sustained through 5 years, with a mean change of -0.6 from baseline in the population who completed 5 years of treatment with adalimumab. Improvements in disease activity, physical function and ASQoL were also sustained through 5 years. BASMIlin was significantly correlated with all evaluated clinical outcomes (P<0.001). The highest correlation was with BASFI at 12 weeks (r = 0.52) and at 5 years (r = 0.65). Multivariate regression analysis confirmed this association (P<0.001). Conclusion. Treatment with adalimumab for up to 5 years demonstrated sustained benefits in spinal mobility, disease activity, physical function and HRQoL in patients with active AS. Spinal mobility was significantly associated with short- and long-term physical function in these patients.
