title: The impact of psoriasis on pregnancy outcomes.
abstract: Psoriasis is an inflammatory disease that affects women in their reproductive years. Other similar diseases have been associated with adverse pregnancy outcomes. We sought to assess whether pregnant women with psoriasis are at higher risk of developing complications, such as preterm birth (PTB) and low birth weight (LBW). A retrospective cohort, performed at two large tertiary centers, evaluated the outcomes of 162 pregnancies in 122 women with psoriasis and 501 pregnancies in 290 women without psoriasis. Univariable and multivariable analyses, adjusting for important demographic factors, comorbidities, or a propensity score, were performed to evaluate the association of psoriasis and a poor outcome composite (POC), including PTB (<37 gestational weeks) and LBW (<2,500  g). Repeated measures analysis was used to account for the multiple pregnancies per woman. Cesarean delivery, preeclampsia/eclampsia, and spontaneous abortion were also evaluated. For women with psoriasis, there was a 1.89-fold increase in odds of POC (95% CI 1.06-3.39) in the univariable analysis. This effect remained statistically significant in the multivariable analyses. Psoriasis was not associated with cesarean delivery, preeclampsia/eclampsia, and spontaneous abortion. This study has shown higher odds of POC in patients with psoriasis. Further larger population-based studies are required to confirm these findings.
