Tumour necrosis factor alpha inhibitor therapy and rehabilitation for the treatment of ankylosing spondylitis: a systematic review.

OBJECTIVES: To systematically review the evidence for a synergistic effect of combining rehabilitation with biological anti-tumour necrosis factor (TNF) therapy in patients with ankylosing spondylitis (AS). METHODS: Data were analysed to identify the most effective rehabilitation programmes, the best endpoints for effectiveness, and patient subgroups most likely to benefit from combination therapy. Systematic MEDLINE and Embase searches were performed to identify studies evaluating rehabilitation programmes and biological therapy in patients with AS. Evidence was categorised by study type, and efficacy, adverse effects and other outcomes were summarised. RESULTS: Of the 75 studies identified, 13 investigated the combination of a rehabilitation programme with TNF inhibitor therapy, while the remainder studied rehabilitation with standard therapy (often not specified). Data from these few studies suggest that combined rehabilitation plus anti-TNF therapy is more effective in terms of symptom severity, disease activity, disability and quality-of-life indices versus biologic alone or rehabilitation with standard medical therapy, or, in non-comparative studies, compared with baseline. The most effective rehabilitation appears to be supervised or in-patient programmes with an educational component. Available data do not provide guidance on most appropriate endpoints or identify patients most likely to benefit from combination therapy. Combined, TNF inhibitor and rehabilitation therapy appear to have a synergistic effect, possibly due to increased adherence to exercise. Exercise regimes are more effective if supervised and include an education component. CONCLUSIONS: Further randomized, controlled trials comparing endpoints and investigating longer-term benefits of combining TNF inhibitors with rehabilitation in different AS subgroups are needed.
