Clinical features and maternal and fetal outcomes in women with Guillain-Barré syndrome in pregnancy

Abstract

Background: Guillain-Barre syndrome (GBS) is an acute inflammatory polyradiculoneuropathy rarely observed during pregnancy.

Methods: In this retrospective study, we analyzed the characteristics of pregnant women with GBS (pGBS) diagnosed in French University Hospitals in the 2002-2022 period and compared them with a reference group of same-age non-pregnant women with GBS (npGBS) identified in the same institutions & timeframe.

Results: We identified 16 pGBS cases. Median age was 31 years (28-36), and GBS developed in the 1st, 2nd, and 3rd trimester in 31%, 31% and 38% of cases respectively. A previous infection was identified in six cases (37%), GBS was demyelinating in nine cases (56%), and four patients (25%) needed respiratory assistance. Fifteen patients (94%) were treated with intravenous immunoglobulins, and neurological recovery was complete in all cases (100%). Unscheduled caesarean section was needed in five cases (31%), and two fetuses (12.5%) died because of cytomegalovirus (CMV) infection (1 case) and HELLP (Hemolysis, Elevated Liver enzymes and Low Platelets) syndrome (1 case). In comparison with a reference group of 18 npGBS women with a median age of 30 years (27-33), pGBS patients more frequently had CMV infection (31% vs 11%), had a prolonged delay between GBS onset and hospital admission (delay > 7 days: 57% vs 12%), more often needed ICU admission (56% vs 33%) and respiratory assistance (25% vs 11%), and more often presented with treatment-related fluctuations (37% vs 0%).

Conclusions: This study shows GBS during pregnancy is a severe maternal condition with significant fetal mortality.
