Abstract

Objectives To describe changes in drug treatment and clinical outcomes of ankylosing spondylitis (AS) during the past decade.

Methods The national database of the German collaborative arthritis centres collects clinical and patient-derived data from unselected outpatients with inflammatory rheumatic diseases. Cross-sectional data from 2000 to 2012 of around 1000 patients with AS per year were compared with regard to clinical presentation and quality of life indicators.

Results Non-steroidal anti-inflammatory drugs (NSAIDs) have been the predominant treatment choice in AS over the years with a prescription rate of 67% of patients in 2012. Currently, almost half of the patients with AS in German rheumatology centres are treated with tumour necrosis factor inhibitors (TNFi). Often, both treatments are used in combination (33%), followed by combinations of NSAIDs and synthetic disease modifying antirheumatic drugs (sDMARDs) with 23% or TNFi alone (21%). In 2012, 10% of patients each received NSAID or sDMARD monotherapy. Methotrexate, sulfasalazine, glucocorticoids and analgaesics alone or in combination with other treatments were given to 10% of patients, respectively. Over the years, we have seen remarkable improvements in disease control and patient reported outcomes. These developments are consistent with enhanced functional status, increasing employment rates and decreasing sick leave, hospitalisation and work disability.

Conclusions In the German rheumatology secondary/tertiary care setting, routine care of patients with AS has changed tremendously during the past decade. Increasingly, more efficacious treatment options are reflected in improved clinical outcomes, quality of life and participation in the labour force.
