Comparison of the predictive value of prooxidant-antioxidant balance and heat shock proteins in the diagnosis of neonatal asphyxia

Asphyxia is one of the important cause of infants' mortality. Accurate and early diagnosis of asphyxia has an important role in performing appropriate protective treatment protocole; therefore, we compared the diagnostic value of two methods of Prooxidant-Antioxidant Balance (PAB) and Heat shock proteins 70 ( HSP70) among  healthy term infants and Neonates with asphyxia. Methods: In this prospective case-control study, we compared the diagnostic value of two methods of  PAB and HSP70 in healthy term infants (N=38) and Neonates with asphyxia (N=30) in Mashhad Ghaem hospital from 2011 to 2015. The diagnostic value of HSP70 and PAB was compared with statistical tests of Chi-square, T-Test, Man-Whitney, Roc curve and regression models. Results: The newborns in two groups were significantly different in terms of the first (P=0.000) and fifth minute Apgar score (P=0.000), HSP70 (P=0.000), PAB (P=0.000), PH (P=0.000), BE (P=0.000) and HCO3 (P=0.015). HSP>0.218 ng / dl has 60% sensitivity and 76% specificity for the diagnosis of asphyxia while PAB>11.3 HK has 84% sensitivity and 92% specificity for the diagnosis of asphyxia. Conclusion: According to the results of this study, HSP70>0.22 ng/dl and PAB>11.3 HK Unite can be used as biochemical markers for the diagnosis of perinatal asphyxia (P=0.001). The sensitivity and specificity of PAB in the diagnosis of asphyxia is higher than HSP70 and Simultaneous measurement of these two markers can correctly diagnose 84% of asphyxia cases.
