To compare serum Lactate Dehydrogenase (LDH) and serum Aspartate Transaminase (AST) of normotensive pregnant women with those of preeclamptic and eclamptic women. To determine the relationship of levels of serum lactate dehydrogenase and serum aspartate transaminase with severity of pregnancy-induced hypertension and its complications.
The study was carried out on pregnant hypertensive patients attending outpatient department of Obstetrics and Gynaecology department, AMCH, Dibrugarh, Assam from 1st July 2013 to 30th June 2014. Normotensive pregnant women were taken as controls. Each serum sample from both the control group as well as study group was estimated for lactate dehydrogenase and aspartate transaminase using standard methods and a comparison is drawn and analysed using t-test and Chi-square test.
Serum lactate dehydrogenase and serum aspartate transaminase levels were higher in the study group in comparison to the study groups. The mean serum LDH was 198±30.03U/L in control group, whereas in preeclampsia and eclampsia, mean serum levels of LDH were 817±114U/L and 927±108U/L, respectively. The levels of the serum AST were found to be less than 600U/L in normotensive and preeclampsia patients and more than 600 U/L in eclampsia and other complications of PIH.
Serum lactate dehydrogenase and serum aspartate transaminase levels in patients suffering from preeclampsia and its complications are consistently higher compared to the normotensive pregnant patients. To determine the usefulness of inclusion of these enzymes along with other cardiac enzymes in the panel of investigations of pregnant women universally needs further large scale comparative studies.
