Abstract

Preeclampsia is associated with an increased cardiovascular risk later in life. Anti-GPCR autoantibodies have been shown to contribute to the development of cardiovascular disease. We investigated whether anti-GPCR autoantibodies are elevated in women with a history of early-onset preeclampsia 8-11 years postpartum, and whether they correlate with clinical outcomes. We investigated data from the Preeclampsia Risk EValuation in FEMales cohort, a retrospective matched case-control study. Anti AT1R-, beta1AR-, ETAR-, PAR1- and CXCR3- autoantibodies were determined in 485 samples by using commercially available ELISA. Women with the lowest combined levels of autoantibodies and a history of early preeclampsia had significantly higher SBP, DBP and MAP (all p<0.001) compared to the controls. The individual titer levels of autoantibodies were not different between controls and former early PE groups 8-11 years postpartum. In conclusion, regulatory autoantibodies alone are not sufficient to explain hypertension or other cardiovascular pathologic conditions, but together with other risk factors such as a previous hypertensive pregnancy, lower levels of autoantibodies are associated with increased blood pressure.
