Abstract
Gestational hypertension is characterized by an imbalance in angiogenic factors. The goal of the current study was to evaluate whether circulating concentrations of proangiogenic and antiangiogenic factors are associated with the risk of progression to preeclampsia and development of adverse outcomes in women with gestational hypertension. We studied 496 women with gestational hypertension. Patients were divided into three groups based on their degree of angiogenic imbalance, evaluated by the soluble fms-like tyrosine kinase-1/placental growth factor ratio: no angiogenic imbalance (≤38), mild angiogenic imbalance (>38-<85), and severe angiogenic imbalance (≥85) or stratified into tertiles according to soluble endoglin (sEng) levels. The concentrations of all angiogenic factors were significantly different in patients with gestational hypertension than in healthy pregnancy. A significant trend towards higher serum sEng levels was observed as the degree of angiogenic imbalance increased. Patients with severe angiogenic imbalance had higher rates of adverse maternal and perinatal outcomes and progression to preeclampsia (P < 0.001) when compared with patients with no or mild angiogenic imbalance. The risk of combined adverse maternal outcomes and specific adverse outcomes (hemolysis, elevated liver enzymes, low platelet count syndrome, preterm delivery, small-for-gestational-age infant, perinatal death, and progression to preeclampsia within 7, 14, 28, and 56 days) was higher in patients with severe angiogenic imbalance or sEng values in the highest tertile (odds ratio ≥5.6 and ≥2.0, respectively), compared with no angiogenic imbalance or the lowest tertile. In women with gestational hypertension at the time of initial evaluation, circulating concentrations of the soluble fms-like tyrosine kinase-1/placental growth factor ratio and sEng appear to be suitable markers to assess the risk of adverse maternal and perinatal outcomes and progression to preeclampsia.
