Background: Inflammatory bowel disease (IBD) is a condition that affects most of the digestive tract. There is no report of fertility reduction in medically managed IBD women compared with the general population. On the other hand, active IBD can lead to significantly decreased fertility. Over the previous 2 decades, anti-tumor necrosis factor (anti-TNF) has been an effective treatment for managing patients with IBD, increasing the use of infliximab and adalimumab in clinical practice. However, it is unclear which biologics are better for pregnant women with IBD.
Aim: We conducted a systematic review and meta-analysis for the risk of adverse pregnancy outcomes following treatment with infliximab and adalimumab in women with IBD.
Methods: Bibliographic databases were retrieved from their inception to July 2022. The results were adverse pregnancy outcomes, including congenital malformations and spontaneous abortion.
Results: A total of 8 studies included 527 pregnant women with IBD. Of these, 343 received infliximab, and 184 received adalimumab therapy. Compared to adalimumab, adverse pregnancy outcomes were not increased in infliximab therapy including congenital malformations and spontaneous abortion.
Conclusion: Infliximab and adalimumab therapy did not show the difference of risk in adverse pregnancy outcomes in women with IBD.
