TO STUDY THE CORRELATION OF URINARY URIC ACID AND CREATININE RATIO IN BIRTH ASPHYXIA
Introduction: Perinatal asphyxia is one of the leading causes of perinatal morbidity and mortality. Feasible and early biochemical markers to diagnose and predict the neurologic outcome is a great need of time as APGAR score alone is inuenced by various factors. The present study was performed to determine the urinary uric acid to creatinine ratio in perinatal asphyxia and its correlation with APGAR score and compare urinary uric acid to creatinine ratio with Sarnat and Sarnat staging. Materials and Methods: This study was carried out on 100 term neonates with an equal number of cases and control 50 each, control group being the neonates with Apgar score ≥ 7 at 1 minute of life and cases being the neonates who suffered from perinatal asphyxia with Apgar < 7 at 1 minute of life. The spot urine sample was collected within 24 hours of birth and their uric acid and creatinine levels were measured and the ratio calculated. Asphyxiated neonates were classied according to Sarnat and Sarnat staging. We Compare UA/Cr ratio with Apgar score and HIE staging using Sarnat and Sarnat staging.Results: On comparison of UUA/Cr among cases and controls we found that ratio was signicantly higher in asphyxiated neonates as compared to non asphyxiate neonates. (Control vs. Cases Group: 2.4 ± 1 vs. 3.6 ± 1.5; p –value < 0.0001). On comparison of UUA/Cr among cases with Sarnat and Sarnat staging of HIE, there is a signicant difference observed in mean UA/Cr ratio across Sarnat and Sarnat staging of HIE (F – Value = 68.760; p – value = 0.0001). Conclusion: Urinary uric acid and creatinine ratio can be used as markers for perinatal asphyxia for screening in centers where other markers for assessing perinatal asphyxia are not available. Urinary uric acid and creatinine ratio is a non-invasive, cheap and easily available marker for assessing the severity perinatal asphyxia.
