DETECTION OF CORTICOSTEROIDS IN UMBILICAL CORD BLOOD IN PREGNANCY FOLLOWING ADRENALECTOMY

Background. Serum lipids including total cholesterol (TC), triglycerides (TG), and low density lipoprotein cholesterol (LDL-C) are increased in pregnancy. Serum proprotein convertase subtilisin kexin 9 (PCSK9) is a significant player in lipoprotein metabolism. Circulating PCSK9 downregulates the LDL receptor on the surface of the liver, inhibiting clearance of LDL-C. Therefore, our study assessed serum PCSK9 concentrations at parturition (Maternal) compared to a nonpregnant (Control) cohort, as well as between mother and newborn (Maternal and Newborn). Methods. Blood was collected from women at parturition and from umbilical cords. Serum lipids and PCSK9 were measured and data were analysed for significance by Mann-Whitney U test at P<0.05 and presented as median levels. Spearman's correlations were made at a 95% confidence interval. Results. Serum PCSK9 was significantly higher in Maternal versus Control cohorts (493.1 versus 289.7 ng/mL; P<0.001, resp.), while the Newborn cohort was significantly lower than Maternal (278.2 versus 493.1 ng/mL; P<0.0001, resp.). PCSK9 was significantly correlated with TC and HDL-C in Maternal and with TC, LDL-C, and HDL-C in Newborn cohorts. Conclusions. Our study provides the first quantitative report on PCSK9 in pregnancy (at parturition) and in umbilical cord blood. Further research will determine how these changes may affect lipoprotein levels during this physiological state.

In Pregnancy

Background: Pregnancy induced hypertension (PIH) is a multisystem disease of unknown etiology which affects only human beings. It poses several problems to both mother and child. Complications in newborns like intrauterine death (IUD), intrauterine growth retardation (IUGR), perinatal asphyxia, neonatal sepsis and bleeding disorders are associated with toxaemia of pregnancy. To decrease the perinatal morbidity and mortality, babies of hypertensive mothers should be carefully monitored and managed. Aim of this study was to establish the changes in total platelet count, reticulocyte count and absolute neutrophil count of umbilical cord blood in pregnancy induced hypertension as compared to normotensive mothers.Methods: This case-control study was conducted among 60 subjects including 30 case (diagnosed cases of pregnancy induced hypertension) and 30 control (normotensive pregnant women). The case group was again categorized into three subgroups – gestational hypertension (06), pre-eclampsia (16) and eclampsia (08). In all the subjects, 2 ml of umbilical cord blood anticoagulated with EDTA was collected and haematological tests for reticulocyte count, total platelet count (TPC) and absolute neutrophil count was done.Results: There was significant decrease in TPC (p<0.01) and absolute neutrophil count (p<0.01), but significant rise in reticulocyte count (p<0.05) in umbilical cord blood of babies born to hypertensive mothers compared to normotensive mothersConclusions: From this study, it can be concluded that newborns of hypertensive mothers carry risks for infection and bleeding complications. So, these simple haematological tests can be done at early stage in neonates to reduce possible perinatal morbidities and mortality.
