Abstract

Objective: Systemic vasculitis (SV) are uncommon diseases that rarely affect women during their reproductive age; little data, mainly retrospective, is available on this topic. The aim of our study was to evaluate maternal/neonatal outcome and disease course before, during and after pregnancy.

Methods: Sixty-five pregnancies in 50 women with SV were followed by a multispecialistic team in 8 institutions between 1995 and 2014. Clinical data on pregnancy, 1year before and 1year after delivery was retrospectively collected. The rate of pregnancy complications was compared to that of a General Obstetric Population (GOP) of 3939 women.

Results: In 2 patients the diagnosis of SV was done during pregnancy; 59 out of the remaining 63 started when maternal disease was quiescent. We recorded 56 deliveries with 59 live births, 8 miscarriages and 1 fetal death. In SV, preterm, particularly early preterm (<34weeks) deliveries and cesarean sections appeared significantly more frequent than in GOP (11.3% vs 5.0%, p=0.049 and 48.2% vs 31.0%, p=0.009). Vasculitis-related complications occurred in 23 pregnancies (35.4%), with 5 severe events (7.7%) including 3 cases of transient ischemic attack (TIA). Data about the post-partum period were available for 56 pregnancies: 12 flares (21.4%) occurred, with 1 severe event (1.8%).

Conclusion: SV patients can have successful pregnancies (especially during a disease remission phase) despite an increased rate of preterm delivery. Severe flares were limited, but the occurrence of 3 TIA suggests that particular attention should be given to possible thrombotic complications in SV patients during pregnancy and puerperium.
