Correlation of elevated levels of lipoprotein(a), high-density lipoprotein and low-density lipoprotein with severity of preeclampsia: a prospective longitudinal study.

The aim of this study was to examine a possible association between the levels of total serum cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and lipoprotein(a), and the development of severe preeclampsia. We measured the levels of these lipoproteins in a prospective observational longitudinal cohort study that recruited 50 third-trimester pregnant women with mild preeclampsia at the time of recruitment. Two assessments were performed; the first measurement was at 29-31 weeks of pregnancy (at recruitment), and the second took place 4 weeks later. Patients with BMI 30, those < 20 years of age and those > 35 years of age were not included in the study. Eight mildly preeclamptic women developed severe preeclampsia within 4 weeks. In these patients, lipoprotein(a) level showed a twofold increase. A serum lipoprotein(a) level > 40.5 mg/dL in a mildly preeclamptic patient predicted the development of severe preeclampsia later on in the pregnancy, whereas a serum lipoprotein(a) level > 52.5 mg/dL was a marker of severity with high sensitivity and specificity. We suggest through our results that that lipoprotein(a) level correlates with the severity of the disease.IMPACT STATEMENT
