Evaluating the Association between Assisted Conception and the Severity of Preeclampsia

Abstract

Objective. To investigate the association between assisted conceptions and preeclampsia (PEC), including assessment of severity of disease. Methods. In a prospective case control study, cases were selected from women with preeclampsia and controls from women without preeclampsia. Exposure was defined as assisted conception with intrauterine insemination or in vitro fertilization (IUI or IVF). We assessed the association between exposure and outcome, using Chi square or Fisher's exact tests. Stratified analyses and multivariable logistic regression were used to control for confounders. Results. Preeclampsia was associated with assisted conception after controlling for age and race (AOR 2.2, [1.03–4.72]). All women with preeclampsia who had assisted conceptions demonstrated severe disease and were more likely to have abnormal lab values: AST >45 (AOR = 6.01 [1.63–22.21] P=0.007), creatinine ≥1 (AOR 2.92 [0.82–10.4], P=0.09) or platelets <100 (AOR 5.74 [1.00–32.76] P=0.049), after adjusting for race, age, and multiple gestations. Conclusion. Assisted conceptions are associated with a more severe preeclamptic phenotype.
