Uric Acid in Pregnancy: New Concepts

Area of Science:

• Obstetrics and Gynecology
• Nephrology
• Clinical Chemistry

Background:

• The link between hyperuricemia and hypertension is known, but uric acid's role in severe preeclampsia remains unclear.
• Recent studies suggest elevated serum uric acid levels in severe preeclampsia patients correlate with disease severity and fetal outcomes.

Purpose of the Study:

• To investigate the role of serum uric acid levels in the clinical course of severe preeclampsia.
• To determine if elevated uric acid is a biomarker for severe preeclampsia and associated adverse effects.

Main Methods:

• A prospective, cross-sectional comparative study of 200 patients (100 severe preeclampsia, 100 normotensive pregnancy).
• Measured serum uric acid levels (mg/dL), clinical variables, laboratory data, and fetal growth.
• Analyzed data using chi-square and Mann-Whitney U tests, with p < 0.05 considered significant.

Main Results:

• A significant difference (p=0.05) in serum uric acid levels was found between severe preeclampsia and normotensive groups.
• Patients with severe preeclampsia and uric acid ≥ 6.0 mg/dL showed significant differences in fetal complications and maternal variables compared to healthy controls.

Conclusions:

• Serum uric acid levels ≥ 6.0 mg/dL may serve as a valuable biomarker for severe preeclampsia.
• Elevated uric acid is associated with increased adverse fetal and maternal effects in severe preeclampsia.
