Adverse Pregnancy and Maternal Outcomes in Women with Hidrad
Hidradenitis suppurativa (HS) disproportionately affects women of childbearing age. However, pregnancy and maternal outcomes for women with HS are unknown.

This study aimed to compare risk of adverse pregnancy and maternal outcomes among women with and without HS, and to evaluate influence of comorbid conditions.

-- Compared to control pregnancies (n=64,218), HS pregnancies (n=1,862) had higher risk of spontaneous abortion (15.5% vs 11.3%), preterm birth (9.1% vs 6.7%), gestational diabetes mellitus (11.6% vs 8.4%), gestational hypertension (6.1% vs 4.4%), preeclampsia (6.6% vs 3.8%), and cesarean section (32.4% vs 27.1%).

-- Relative risk of some pregnancy and maternal outcomes were attenuated after comorbidity adjustment.

-- In the fully adjusted model, HS pregnancies were independently associated with spontaneous abortion, gestational diabetes mellitus, and cesarean section.

Conclusively, HS appears to be an independent risk factor for adverse pregnancy and maternal outcomes. This risk is influenced by comorbidities that may be modifiable with early identification and management.
