Decreased Risk of Preeclampsia in Women with Inflammatory Bowel Disease on Anti-Tumor Necrosis Factor Therapy
Overview
Affiliations
Background: Evidence suggests that upregulation of tumor necrosis factor-alpha (TNF-α) plays a role in immune dysregulation in both preeclampsia and inflammatory bowel disease (IBD).
Aims: We aimed to investigate whether anti-TNF therapy during pregnancy decreases the risk of preeclampsia in women with IBD.
Methods: The study population included women with IBD and pregnancies who were followed at a tertiary care center from 2007 to 2021. Cases of preeclampsia were compared with controls with a normotensive pregnancy. Data on patient demographics, disease type and activity, pregnancy complications, and additional risk factors for preeclampsia were collected. The association between anti-TNF therapy and preeclampsia was analyzed using univariate analysis and multivariate logistic regression.
Results: Women with preeclampsia were more likely to have a preterm delivery (44% vs. 12%, p < 0.001). More women without preeclampsia were exposed to anti-TNF therapy during pregnancy than women with preeclampsia (55% vs. 30%, p = 0.029). The majority of women (32/44) on anti-TNF therapy, either adalimumab or infliximab, continued to have some degree of exposure during the third trimester. Though not significant, multivariate analysis showed a trend towards a protective effect of anti-TNF therapy against developing preeclampsia if exposed during the third trimester (OR 0.39; 95% CI 0.14-1.12, p = 0.08).
Conclusions: In this study, anti-TNF therapy exposure was higher in IBD patients who did not develop preeclampsia than in those who did. While not significant, there was a trend towards a protective effect of anti-TNF therapy against preeclampsia if exposed during the third trimester.
