Urinary uric acid or urinary creatinine ratio as a non-invasive marker for perinatal asphyxia

Siddharth ., Preeti Lata Rai, P. L. Prasad

Abstract


Background: Perinatal asphyxia is amongst the common problem of neonates and there exists a significant contribution to the neonatal morbidity and mortality. It is observed as a common and a vital cause of the preventable cerebral injury. The prediction of the perinatal asphyxial outcome is very important but dreadful. There is a limited role for APGAR score to predict the immediate outcome, like HIE and the long-term neurological sequelae observational error may happen in APGAR. But the biochemical parameters can truly be relied upon. This study was done to assess urinary uric acid/urinary creatinine ratio (UA/Cr) as a non-invasive marker for perinatal asphyxia and co-relate its absolute value to the degree of the perinatal asphyxia.

Methods: In this prospective case control study conducted in the Pediatrics Department of Shri Ram Murti Smarak Institute of Medical Sciences between Nov 2017 to May 2019, 42 asphyxiated and 42 non-asphyxiated newborns were included. Detailed history and assessment were for all the enrolled newborns. Spot urine samples were sent for the uric acid and creatinine estimation. Results were documented, and statistical analysis was performed.

Results: Urinary uric acid to creatinine ratio used as additional non-invasive, early and easy biochemical marker of the birth asphyxia that biochemically supports severity grading and clinical diagnosis of the asphyxia by APGAR score.

Conclusions: The ratio of the urinary uric acid and creatinine enables rapid and early recognition of asphyxial injury and also the evaluation of its severity and potential for short-term morbidity or death.
