Introduction: Preeclampsia (PE) is a serious pregnancy-induced disease characterized by hypertension, proteinuria and other systemic disorders after 20 weeks of gestation and is a leading cause of maternal and fetal morbidity and mortality. The main pathological characteristics of preeclampsia are poor trophoblast cell invasion and uterine spiral artery remodeling dysfunction caused by placenta ischemia and oxidative stress. Nowadays, preeclampsia is considered to be the results of the interactions of genetic and environmental factors. However, its accurate pathogenesis remains unknown. It was considered IGF-1 might be involved in the pathogenesis of preeclampsia. As is known, the behaviors of cells, the formation of placenta and the growth of fetus are widely regulated by insulin-like growth factor 1 (IGF-1). Several studies have shown that IGF-1 was significantly reduced in preeclampsia. Objectives: To assess the role of Insulin like Growth Factor-I (IGF-I) as a Predictor of Preeclampsia. Materials and Methods: It was a prospective cohort study conducted in General Obstetrics and Gynaecology Unit OPD, Dhaka Medical College Hospital from January, 2020 to December, 2020. Pregnant women between 8 weeks to 15 weeks were enrolled for study after fulfilling selection criteria. Serum concentration of Insulin like growth factor-I (IGF-I) was assessed with cut off value of IGF-I 175.9 ng/ml. The value above 175.9 ng/ml was categorized as normal IGF-I and value below 175.9 ng/ml was categorized as low IGF-I. The patients who had value above 175.9 ng/ml were grouped as A. The value below 175.9 ng/ml was grouped as B. Then they were followed up monthly upto 28 weeks, two weekly upto 36 weeks, weekly upto delivery and puerperium for development of preeclampsia or not. All information was recorded in data collection sheet. Data were analyzed by SPSS-23. Data were compared and correlated among groups and presented by tables and figures. Result: Maternal serum concentration .....
