[Is retardation of radiologic progression of ankylosing spondylitis possible?]

In the introduction is the author dealing with problems of early diagnosis of ankylosing spondylitis and he is explaining the advantages of new ASAS/EULAR criteria for diagnosis of axial spondylarthritis. Than he continues with discussion about new "Recommendations for treatment of ankylosing spondylitis", stressing the modification of recommendations for anti-TNF therapy. Despite the fact, that high symptomatic efficacy of anti-TNF therapy was confirmed, there is no clear evidence that anti-TNF drugs delay radiologic progression. On the contrary, study with nonsteroidal antirheumatic drugs in duration 24 months was performed and have documented that patients treated continuously by celecoxib had smaller radiographic progression than patients treated with celecoxib on demand. Anti-TNF therapy delays radiographic progression in rheumatoid arthritis, but not NSAID, in ankylosing spondylitis it is opposite. The differences may be caused by different pathophysiology of rheumatoid arthritis and ankylosing spondylitis as it is explained in the next part of publication. Combination therapy of AS with anti-TNF and continuous celecoxib therapy could be very interesting.
