Serum glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase activity in premature and full-term asphyxiated newborns.

The serum activity of SGOT and SGPT is one of the more specific parameters of liver cell injury both in adults and in the pediatric age-group. The determination of serum transaminase activity could offer a routine and rapid laboratory test for establishing the presence of hepatic cellular damage following intrauterine or perinatal asphyxia. In fact, it appears that there is a correlation between hypoxia and the increase in serum activity of transaminases in full-term and premature asphyxiated newborns. However, this increase is reversible up to the 30th day of life. The behavior of transaminase enzymatic activity in premature asphyxiated newborns compared to full-term asphyxiated newborns suggests a higher resistance of membranes to hypoxic-ischemic injuries and a lower enzymatic pool of cellular metabolism in premature newborns. Therefore, knowledge of the behavior of SGOT and SGPT activity may have important implications in the diagnosis and early treatment of perinatal asphyxia.
