title: Serum enzyme tests in hepatosplenic schistosomiasis.
abstract: The serum activities of monoamine oxidase (MAO), gamma-glutamyl transferase (GGT) and glutamic dehydrogenase (GDH) enzymes were measured in 25 patients with Schistosoma mansoni infection (Group I), 26 patients with schistosomal hepatosplenomegaly and ascites (Group II) and 21 normal controls. The activities of these enzymes were compared with those of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The mean levels of MAO, GGT and GDH of Group I were not significantly different from controls. The mean levels of MAO and GGT in Group II, however, were significantly different from corresponding mean levels of Group I and the controls at P less than .001. Changes in the mean level of GDH and ALT were not significant. By contrast, the levels of AST and ALP in both groups showed significant elevation over control levels at P less than .001. These results indicate that estimation of the two enzymes MAO and GGT may aid in the biochemical differentiation of the stages of schistosomiasis and their associated hepatic complications.
