The Relationship Between Malnutrition and Liver Enzymes in Hospitalized Children in Zahedan: A case-Control Study

 Malnutrition causes nutritional, metabolism, and biochemical disorders and finally leads to mortality. Several studies have highlighted that serum liver enzymes are increased in patients with malnutrition.

 This study aimed to evaluate the relationship between malnutrition and liver enzymes in hospitalized children in Zahedan.

 This case-control study was conducted among 145 hospitalized children under six years old, including 74 cases and 71 controls. The case group was diagnosed with malnutrition according to weight for age indices (Z-Score < -2SD), and controls were determined based on the following indices (Z-Score > -2SD) of classification of WHO 2006 growth standards. Serum was isolated after taking blood from the samples. Then liver enzymes, including AST, ALP, and ALT, were measured by spectrophotometric method.

 A total of 145 subjects were enrolled that consisted of 74 cases and 71 controls. No significant difference was observed in serum liver markers, including AST, ALT, and ALP between the two groups, However, the level of AST, ALT, and ALP was higher than the standard level. There was a significant correlation between AST with ALT (r = 0.74, P < 0.001), and ALP (r = 0.27, P = 0.03).

 The findings indicated that there was no significant alteration in enzyme markers in the two groups. However, AST and ALT levels increased, and ALP levels decreased compared with the control. Different degrees of malnutrition, including mild, moderate, and severe, can probably change the levels of hepatic enzymes in under-nourished children. Alteration of these liver enzymes could be due to the metabolic modification, which can be the result of protein deficiency.
