Pregnancy outcome in four women with inflammatory bowel disease treated with budesonide MMX

BACKGROUND

Maintaining disease remission throughout pregnancy in women with inflammatory bowel disease is of the utmost importance to decrease the risk of adverse outcome. In general, corticosteroids are safe to use during pregnancy, but no data exist in the specific use of budesonide MMX. We report four cases of budesonide MMX in pregnancy and pregnancy outcome.

METHODS

Four women with inflammatory bowel disease experienced disease activity during pregnancy. They were treated with budesonide MMX in an attempt to obtain clinical remission. Disease activity was assessed through physician's global assessment as well as lower endoscopy.

RESULTS

Budesonide MMX proved effective in achieving remission in three out of four women. One woman had an uncomplicated colectomy in the second trimester. All children were born normal for gestational age, with no congenital abnormalities and have reached all their developmental milestones. The four children have received vaccines according to the national immunization program without complications.

CONCLUSION

No adverse pregnancy outcomes were reported after the use of budesonide MMX. To our knowledge, this is the first report on the safety of budesonide MMX treatment in pregnant women with inflammatory bowel disease.

Long-Term Safety of In Utero Exposure to Anti-TNFα Drugs for the Treatment of Inflammatory Bowel Disease: Results from the Multicenter European TEDDY Study

OBJECTIVES

The long-term safety of exposure to anti-tumor necrosis factor (anti-TNFα) drugs during pregnancy has received little attention. We aimed to compare the relative risk of severe infections in children of mothers with inflammatory bowel disease (IBD) who were exposed to anti-TNFα drugs in utero with that of children who were not exposed to the drugs.

METHODS

Retrospective multicenter cohort study. Exposed cohort: children from mothers with IBD receiving anti-TNFα medication (with or without thiopurines) at any time during pregnancy or during the 3 months before conception. Non-exposed cohort: children from mothers with IBD not treated with anti-TNFα agents or thiopurines at any time during pregnancy or the 3 months before conception. The cumulative incidence of severe infections after birth was estimated using Kaplan-Meier curves, which were compared using the log-rank test. Cox-regression analysis was performed to identify potential predictive factors for severe infections in the offspring.

RESULTS

The study population comprised 841 children, of whom 388 (46%) had been exposed to anti-TNFα agents. Median follow-up after delivery was 47 months in the exposed group and 68 months in the non-exposed group. Both univariate and multivariate analysis showed the incidence rate of severe infections to be similar in non-exposed and exposed children (1.6% vs. 2.8% per person-year, hazard ratio 1.2 (95% confidence interval 0.8-1.8)). In the multivariate analysis, preterm delivery was the only variable associated with a higher risk of severe infection (2.5% (1.5-4.3)).

CONCLUSIONS

In utero exposure to anti-TNFα drugs does not seem to be associated with increased short-term or long-term risk of severe infections in children.
