Abstract :
There is increasing evidence that oxidative stress may play a role in the pathophysiology of hyperemesis gravidarum. Serum paraoxonase-1 (PON-1) is a high density lipoprotein (HDL)-associated enzyme that prevents oxidative modification of low density lipoprotein. The aim of the study was to measure the serum levels of PON-1 activity in women with hyperemesis gravidarum. Thirty-four women with hyperemesis gravidarum and 31 healthy pregnant women were enrolled in the study. Serum PON-1 activity was measured spectrophotometrically. Lipid hydroperoxide (LOOH) levels were measured by iodometric assay. PON-1 activity was significantly lower and LOOH levels were significantly higher in pregnant women with hyperemesis gravidarum than in healthy pregnant women (P < 0.0001, for all). There were significant correlations between PON-1 and LOOH, triglyceride, total cholesterol, HDL, low density lipoprotein (LDL) and high sensitive C-reactive protein (HSCRP; P < 0.0001, for all). By using multiple regression analysis LDL, HDL, HSCRP and LOOH were independent determinants of serum PON-1 activity in the study. Decreased PON-1 activity might be related to increased oxidative stress and inflammation in pregnant women with hyperemesis gravidarum. Subjects with hyperemesis gravidarum might be more prone to the development of atherogenesis due to low serum PON-1 activity. |
