Key clinical point: A significant and independent association was observed between the serum soluble suppression of tumorigenicity 2 (sST2) and N-terminal probrain natriuretic peptide (NT-proBNP) levels during the second or early-third trimester and the onset of preeclampsia in women with twin pregnancies.
Major finding: Twin pregnancies with vs without preeclampsia were associated with significantly higher maternal serum levels of sST2 and NT-proBNP in the second and early-third trimesters (both P < .001), with a serum sST2 level of ≥30.7 ng/mL (odds ratio [OR] 8.13; P < .001) and NT-proBNP level of ≥282.2 pg/mL (OR 7.20; P < .001) being independently associated with the occurrence of preeclampsia in twin pregnancies.
Study details: Findings are from a longitudinal nested case-control study that included women with dichorionic twin pregnancies from a prospective cohort and compared women with (n = 78) and without (n = 78) preeclampsia.
