Background: Preeclampsia is characterized by development of high blood pressure and proteinuria. It affects 5–8% of all pregnancies and is a major contributor to maternal and fetal morbidity and mortality. There is no single test that fulfils all the criteria for a good predictor of preeclampsia and associated renal damage.
Aims & Objectives: To evaluate the role of serum and urine biochemical parameters as early predictors of preeclampsia. To investigate the role of BUN: Creatinine ratio in diagnosing preeclampsia and evaluating prognosis of the disease.
Material and Methods: In the present prospective study, one hundred and twenty pregnant women divided into three groups: normotensive (control), women at high risk and with preeclampsia were included. Analyses of different biochemical parameters including BUN: Creatinine were carried out.
Results: There was significant difference in the mean value of serum uric acid, blood urea nitrogen, creatinine, urinary protein and BUN: Creatinine ratio in preeclampsia group compared to control group (p < 0.001). There was significant difference (p < 0.05) in serum uric acid between control and preeclampsia group. However, there was no significant change in haematocrit, serum creatinine and urine protein between control and high risk group.
Conclusion: BUN: Creatinine ratio in pregnant women with preeclampsia and also in high risk group was significantly increased (t = 15.55, p < 0.001 and t = 8.66, p < 0.001 respectively) in comparison to the control group. This index could be useful in evaluating the severity of preeclampsia and could be used as a predictor in prognosis of preeclampsia and subsequent early renal disease.
