Abstract

AST levels have been reported to he increased concern children and adults with COVID-19 infection. The majority of these cases with an increased AST level have clinically advanced COVID-19 disease. A wide range of possible mechanisms responsible for the increased.

AST level have been advanced, but no single factor been identified as being responsible. Laboratory evidence for either a subclinical coagulopathy in children or an overt coagulopathy in adults is frequently present in individuals with increased AST level, who are infected with COVID-19. Most likely, a combination of factors contributing to the increased AST levels and COVID-19 infected adults. In contrast, no single or combination of factors has been identified as being responsible for the increased AST levels in children. It has been proposed by several groups in Asia that t" l,! immaturity of the neonatal liver I’ll be responsible, but no specific factor of the immature liver has been proposed or identified.

Recognizing that the problems of an abnormal AST children is highest in those less than age 2 and declines progressively thereafter such that rare cases of AST elevations are identified in children age more than 2 and declines through age 5 years. Recognizing this age-dependent prevalence of an elevated AST in children infected with COVID-19, it is proposed to be the failure to develop Lepetic plates with endothelial cell linings resulting in the creation of a subendothelial space variant mononuclear cells consisting of macrophages, functional B cells that selectively secrete IgA as well as a wide array of cytokines that in combination with T cells that protect the liver from viral induced liver cell injury.
