Abstract

Objectives: Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that affects the peripheral nervous system. The purpose of our study was to evaluate maternal and fetal/neonatal outcomes among pregnancies complicated by GBS.

Methods: We performed a retrospective cohort study using the Healthcare Cost and Utilization Project - National Inpatient Sample from the United States. ICD-9 codes were used to identify all pregnant women who delivered between 1999 and 2015 and had a diagnosis of GBS. The remaining women without GBS who delivered during that time period constituted the comparison group. The associations between maternal GBS and obstetrical and fetal/neonatal outcomes were evaluated using multivariate logistic regression, while adjusting for the confounding effects of maternal characteristics.

Results: Of 13,792,544 births included in our study, 291 were to women with GBS, for an overall incidence of 2.1/100,000 births. A steady increase in maternal GBS was observed over the study period (from 1.26 to 3.8/100,000 births, p=0.02). Further, women with GBS were more likely to have pregnancies complicated by preeclampsia, OR 1.69 (95 % CI 1.06-2.69), sepsis, 9.30 (2.33-37.17), postpartum hemorrhage, 1.83 (1.07-3.14), and to require a transfusion, 4.39 (2.39-8.05). They were also at greater risk of caesarean delivery, 2.07 (1.58-2.72) and increased length of hospital stay, 4.48 (3.00-6.69). Newborns of women with GBS were more likely to be growth restricted, 2.50 (1.48-4.23).

Conclusions: GBS in pregnancy is associated with maternal and newborn adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy and in the postpartum period.
