Pregnancy-Onset Acute Severe Colitis after in vitro Fertilization Embryo Transfer

Inflammatory bowel diseases (IBD) usually affect women in their fertile years and, therefore, have implications for their fertility and pregnancy. The presence of IBD during pregnancy has been shown to adversely affect pregnancy outcomes, and increased rates of preterm delivery and of spontaneous abortion have been reported. An onset of acute severe colitis in pregnancy has rarely been seen. We present the case of a 42-year-old woman who conceived after 9 attempts of in vitro fertilization and whose pregnancy was the result of a donated oocyte. Shortly after conception, she was diagnosed with severe active ulcerative colitis, and biologic therapy was introduced in the 28th week of pregnancy. Although therapy for IBD in pregnancy is considered safe for most drugs, this was not very well known in 2015. We also consider our case exceptional because we now have a 5-year follow-up of our patient and her child after having begun biologic therapy during late pregnancy.
