title: Are Immunosuppressants Becoming Obsolete?
abstract: Historically, in the 1950s, the introduction of simple, old-fashioned steroids resulted in a significant drop in mortality and hence offered for the first time a real therapeutic option for patients with inflammatory bowel disease. However, as we are all aware of, steroids are no option for maintenance of remission. This review will provide an overview of the available data on the current role of azathioprine in the therapy of Crohn's disease. Based on several controlled trials, the place of azathioprine for maintenance of remission is indisputable. Data from a pediatric cohort suggested that early introduction of azathioprine is beneficial for the disease course. Two recent studies aimed at reproducing these data in adult populations and failed. Hence indicating that azathioprine should only be introduced for maintenance of remission in a step-up-wise approach. An additional role for azathioprine in combo therapy with TNF antibodies has been indicated by several trials revealing a substantial benefit on response. This is partly attributed to the gain in the therapeutic effect by azathioprine itself and possibly through reduction of anti-drug antibody development. In summary, the current role of azathioprine in the therapy of Crohn's disease is manifold and still has an impact in times of targeted therapy.
