Study of urinary uric acid to creatinine ratio as a biochemical marker of perinatal asphyxia and its correlation with Apgar Score

Abstract

Background: Perinatal asphyxia is a common neonatal problem and contributes significantly to neonatal morbidity and mortality. Every hour, 104 children die as a result of asphyxia. In India; between 250,000 to 350,000 infants die each year secondary to birth asphyxia and mostly within the first three days of life. The present study was performed to determine the Urinary Uric Acid to Creatinine Ratio in perinatal asphyxia and its correlation between APGAR score and urinary uric acid to creatinine ratio in perinatal asphyxia.Methods: A randomized case control hospital-based study was conducted on 50 asphyxiated and 50 normal newborn. Urinary uric acid and creatinine were estimated in spot urine within 24 hours after birth in both cases and controls. A ratio between the concentrations of uric acid to creatinine was estimated and comparison done between cases and controls.Results: Urinary uric acid to creatinine ratio can be used as an additional non-invasive, easy and early biochemical marker of birth asphyxia which biochemically supports the clinical diagnosis and the severity grading of asphyxia by APGAR score.Conclusions: Urinary uric acid to creatinine ratio can be used as an additional non-invasive, easy and early biochemical marker of birth asphyxia which biochemically supports the clinical diagnosis and the severity grading of asphyxia by APGAR score.
