The incidence of inflammatory bowel disease (IBD; Crohn ’ s disease, ulcerative colitis) is highest during the peak reproductive years, hence the increased concern with the safety of IBD drugs during pregnancy. Over the past 11 years, anti-TNF-α antibody therapy has emerged as a treatment approach for refractory IBD patients who have failed to achieve or maintain remission with corticosteroids and immunomodulator agents. The TNF-α inhibitors (anti-TNFs; infliximab, adalimumab, certolizumab pegol) have proven successful in inducing and maintaining remission of moderateto- severe IBD, but recommendations for the use of these compounds during pregnancy have lacked consensus. Balanced against the potential risk of these drugs on the fetus is the well-established fact that high disease activity has been found to poorly affect pregnancy outcomes in IBD, and the potential use of anti-TNF agents may control disease flare and severity during pregnancy. Concerns regarding the effect of anti-TNFs on the pregnancy and fetus have been assuaged by registry data which has demonstrated an overall positive safety record. Both the U.S. Food and Drug Administration and the European Crohns and Colitis Organization categorize anti-TNF agents as safe during pregnancy. New knowledge regarding the physiologic timing of placental transfer of therapeutic antibody subclasses and pegylated antibody fragments from the mother into the fetus has also helped to allay concerns. This review will examine the present state of knowledge regarding the use of anti-TNFs in pregnant women with IBD.
