Background: Hypertension is a common medical disorder seen in pregnancy and it is responsible for significant maternal and perinatal morbidity and mortality especially in developing countries. Maternal serum uric acid correlates with both severity of maternal disease and perinatal morbidity/mortality and may influence timing of delivery of the fetus to avoid further intrauterine complications. This would improve fetal survival, hence decreasing fetal morbidity and mortality. Objective: To determine the prognostic value of maternal serum uric acid level in determining perinatal outcome in hypertensive disorders in pregnancy, and to determine its association with disease severity. Study design: Hospital based cross-sectional study. Study area: Department of Obstetrics and Gynaecology of the University of Maiduguri Teaching Hospital, Maiduguri, Nigeria. Methodology: Patients were recruited consecutively as they were admitted into the labour ward with a hypertensive disorder in pregnancy. The next two normotensive non proteinuric pregnant women matched for age group and parity admitted into the labour ward were taken as control. Socio-demographic variables and clinical characteristics such as age, parity, admitting blood pressure, degree of proteinuria, mode of delivery, gestational age at delivery, birth weight, Apgar score at 1st and 5th minute and admission to special care baby unit were noted. Levels of maternal serum uric acid, liver enzymes, urine creatinine, spot urinary proteincreatinine ratio, packed cell volume and platelet count were recorded.
