A Comparative Study of Serum Uric Acid Level in Normal Pregnant and Preeclamptic Ladies

Preeclampsia is a serious pregnancy complication characterized by hypertension, proteinuria with or without pathological edema. According to some studies, serum uric acid lacks sensitivity and specificity as a diagnostic tool whereas another group of the researchers indicated uricemia as a predictor of preeclampsia in pregnant ladies. The present study was designed to assess whether serum uric acid can be used as a biochemical indicator or not in preeclamptic patients. Pre-eclamptic patients admitted in Nalanda Medical College Hospital from January 2013 to September 2013 were included in this study. Age matched normal healthy pregnant ladies served as control. The record of their blood pressure and serum uric acid level was evaluated. Results showed significantly high blood pressure [SBP 148.32+14.52 vs 110.00+8.21 mm Hg; DBP 97.49+8.69 vs 73.6+7.43 mm Hg], and serum uric acid level [6.31+1.35 vs 4.22+0.59 mg/dl] in pre-eclamptic patients compared to their healthy counterparts. Uric acid is a terminal metabolite of the degradation of nucleotides, which increases their blood levels in patients with preeclampsia increasing its synthesis by damage and death of trophoblastic cells and proliferation. Uricemia in preeclampsia likely results from reduced uric acid clearance from diminished glomerular filtration, increased tubular reabsorption and decreased secretion. Results of the present study indicated association of elevated serum uric acid level with preeclampsia which could be used as a biochemical indicator of preeclampsia in pregnant women.
