Abstract

Abstract Introduction: The maternal and fetal outcomes are poorer in pregnancies associated with obstetric complications. A newly recognized marker of hypoxia, serum ischemia-modified albumin (IMA), which serves as an early predictive marker of myocardial infarction in the emergency department, is now being studied in obstetric complications of pregnancy. Aims and Objectives: (1) To study the levels of maternal serum IMA in the early 2nd trimester (12–20 weeks) to predict the occurrence of uncomplicated and complicated pregnancy post 20 weeks of gestation. (2) To evaluate the IMR ratio (IMAR) (serum IMA-to-human serum albumin ratio) and its significance in the obstetric complications of pregnancy. Methodology: This prospective cohort study was conducted on 150 antenatal women with gestational age from 12 to 20 weeks. A complete detailed history of all participants was taken and they were followed up to the time of delivery for the specific complications (i.e., pregnancy-induced hypertension [PIH], preeclampsia, eclampsia, and gestational diabetes in mother and stillbirth, preterm birth, and fetal growth restriction [FGR] in the fetus) that developed during pregnancy. IMA levels and IMA ratio were obtained and correlated with the development of the defined complications of pregnancy. The data were recorded, tabulated, and subjected to statistical analysis. Results: A significant relationship between IMA value and the incidence of PIH, preeclampsia, and eclampsia and between IMAR value and the incidence of preeclampsia and eclampsia was seen among the study population (P < 0.05). We observed that IMA and IMAR values were higher in women who did not have any fetal complications than in women who had fetal complications, namely, stillbirth, preterm birth, and FGR. However, this difference was not significant (P > 0.05). Conclusion: Serum IMA and IMAR levels were higher in women with PIH, preeclampsia, and eclampsia. The most common pregnancy outcome was small for gestation age. No significant link was found between serum IMA levels or IMAR and the severity of eclampsia, gestational diabetes, stillbirth, preterm, and FGR.
