Background:
Pregnant patients with inflammatory bowel diseases (IBDs) are frequently treated with immunomodulatory agents and may be at increased risk of adverse outcomes, including peripartum infections. We sought to examine the risk for peripartum infections in patients with IBD compared with control subjects and identify potential risk factors associated with peripartum infections in these patients.
Methods:
This retrospective cohort study compared peripartum infection rates and associated risk factors between pregnant women with and without IBD. The study population included women attending a dedicated joint maternal-fetal medicine and gastroenterology clinic for pregnant women with IBD between 2012 and 2019 at the Rabin Medical Center in Israel, a major referral center for patients with IBD. For each patient, 5 women without IBD were matched according to the newborn's birth date (±2 years), age, parity, and body mass index. Peripartum infection was defined as any 1 of the following: chorioamnionitis, maternal fever (>38°C) detected during labor or postpartum hospitalization, and positive culture taken during the hospitalization.
Results:
Overall, 195 pregnant women with IBD (72 [37%] with ulcerative colitis, 123 [63%] with Crohn's disease) were matched with 888 control subjects. The mean disease duration was 8.4 ± 7.02 years. IBD therapy, used by 81%, included most frequently 5-aminosalicylic acid (44%) and tumor necrosis factor inhibitors (27%). Peripartum infections were observed in 15 (7.7%) patients and 49 (5.5%) control subjects (P = 1.00). No medication significantly increased the likelihood of peripartum infection. Cesarean delivery was more likely among women with IBD but was not associated with an increased risk of peripartum infection.
Conclusions:
Peripartum infections were comparable in patients with IBD and control subjects. These reassuring data augment existing knowledge of obstetrical outcomes in IBD patients and contribute to the discussion between caregivers and patients.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
