There is not enough evidence to support any benefit of sulfasalazine in reducing pain , disease activity , radiographic progression , or improving physical function and spinal mobility in the treatment of AS .
A statistically significant benefit in reducing the erythrocyte sedimentation rate and easing spinal stiffness was mentioned in the previous version .
More withdrawals because of side effects occurred with sulfasalazine .
BACKGROUND Ankylosing spondylitis ( AS ) is a chronic inflammatory disease of unknown cause and affects mainly the spine , but can also affect other joints .
Disease progression may result in loss of mobility and function .
Sulfasalazine is a disease-modifying antirheumatic drug used in the treatment of AS .
However , its efficacy remains unclear .

Treatment of active ankylosing spondylitis with infliximab: a randomised controlled multicentre trial
UNLABELLED BACKGROUND Treatment options for patients with ankylosing spondylitis are few . We aim ed to assess the effectiveness of infliximab , an antibody to tumour necrosis factor (TNF)-alpha , in treatment of such patients . METHODS In this 12-week placebo-controlled multicentre study , we r and omly assigned 35 patients with active ankylosing spondylitis to intravenous infliximab ( 5 mg/kg ) and 35 to placebo at weeks 0 , 2 , and 6 . One patient in the infliximab group was withdrawn from the study . Our primary outcome was regression of disease activity of at least 50 % . To assess response , we used vali date d clinical criteria from the ankylosing spondylitis assessment working group , including disease activity ( BASDAI ) , functional indices ( BASFI ) , metrology ( BASMI ) , and quality of life ( short form 36 ) . Analyses were done by intention to treat . FINDINGS 18 ( 53 % ) of 34 patients on infliximab had a regression of disease activity at week 12 of at least 50 % compared with three ( 9 % ) of 35 on placebo ( difference 44 % [ 95 % CI 23 - 61 ] , p<0.0001 ) . Function and quality of life also improved significantly on infliximab but not on placebo ( p<0.0001 and p<0.0001 , respectively ) . Treatment with infliximab was generally well tolerated , but three patients had to stop treatment because of systemic tuberculosis , allergic granulomatosis of the lung , or mild leucopenia . INTERPRETATION Our results show that treatment with infliximab is effective in patients with active ankylosing spondylitis . Since there are some potentially serious adverse effects , we recommend that this treatment mainly be used in co-operation with rheumatological centres
