Progressive ankylosis of the thoracic skeleton in ankylosing spondylitis (AS) causes restrictive pulmonary function impairment characterized by a reduction in vital capacity (VC). After a wash-out period of 2 weeks, 33 men with active AS were treated with either diflunisal or phenylbutazone according to a double blind randomized design for 12 weeks, followed by an open extension period of 36 weeks. A spirometric study was performed at baseline, Week 12, and Week 48.

Throughout the study serum IgA levels correlated most frequently with chest expansion and lumbar flexion index, and patients with extensive radiological changes also had the highest serum IgA levels. Likewise, changes in IgA, but not in IgM and IgG, correlated with changes in a composite index of disease activity (IDA).

In this study patient acceptability of five such agents (benoxaprofen, fenbufen, feprazone, flurbiprofen, ketoprofen) is compared in groups of 50 patients with rheumatoid arthritis. Less than 40 per cent of patients continued on the prescribed drug for six months.

There is variation in the therapeutic approach with heavier reliance on aspirin in the USA. The evolution of JRA from onset subtype to final subtype over 5 years was the same in both groups and was independent of the type of therapy.
