Azathioprine for IBD : Better the devil you know Jeremy D. Sanderson
Azathioprine for inducing remission in active IBD 425 patients (209 AZA/6-MP, 216 placebo) End-points: steroid sparing effect, clinical response Overall response Aza/6-MP54% (CI 47%-61%) placebo 33% (CI 27%-40%) Pooled OR2.36 (CI 1.57 – 3.53) Time to respondPresent 1980av. 3.1 months OR 1.54 if <17 weeks Rx OR 2.51 if >17 weeks Rx Steroid sparingAza/6-MP65% (CI 56%-74%) placebo36% (CI 27%-45%) Pooled OR3.86 (CI 2.14 – 6.96) Sandborn et al, Cochrane Library, Issue 4, 2000
