Adverse pregnancy outcomes in women with Behçet's disease: population-based registry linkage study in Taiwan.

OBJECTIVES

To estimate the risks of adverse pregnancy outcomes in women with Behçet's disease (BD) METHODS: Data collected by the Taiwan National Health Insurance Administration between 2001 and 2012 was used for our study. A total of 2,350,339 pregnancies from the Taiwan National Health Insurance database and birth registry were identified. Maternal history of BD in women was ascertained. A comparison was made to determine whether BD increased the risk of health issues associated with pregnancy and fetal outcomes. Using an adjusted generalized estimating equation model, we estimated the odds ratios (ORs) and 95% confidence intervals (CIs) for fetal-neonatal and maternal outcomes.

RESULTS

There were 99 pregnancies in women with BD and 2,350,240 pregnancies in women without BD. The OR and 95% CI of puerperal cerebrovascular disorders were 12.08 (1.7-85.9), and those of gestational diabetes were 1.89 (1.1-3.25). Both were higher than the values in general pregnant women after adjusting for age, infant sex, urban residence, income, occupation, birth year, and Charlson Comorbidity Index. However, there were no adverse fetal outcomes in pregnant women with BD.

CONCLUSIONS

Patients with BD have no significant risks of multiple complications except for puerperal cerebrovascular disease and gestational diabetes during pregnancy. Close monitoring of blood sugar is suggested. Furthermore, neonatal outcomes were not influenced by BD. Key Points • Patients with Behçet's disease are at a risk of puerperal cerebrovascular disease and gestational diabetes during pregnancy. • The odds ratio and 95% confidence interval for puerperal cerebrovascular disorders were 12.08 (1.7-85.9), and those for gestational diabetes were 1.89 (1.1-3.25). • Pregnant patients with Behçet's disease have no risks of neonatal outcomes.
