Enzyme activities and protein concentrations in serum of patients with hepatosplenic schistosomiasis.
The hepatosplenic form of Schistosoma mansoni infection contributes considerably to morbidity and mortality in endemic areas. The present study investigated serum protein concentrations and serum enzyme activities of 58 Sudanese patients with hepatosplenic schistosomiasis. All of them had a history of infection with S. mansoni and one or several episodes of oesophageal bleeding due to portal hypertension. Diagnosis was based on clinical (n = 24), ultrasonographical (n = 18) and histological (n = 16) grounds. The control group consisted of 40 Sudanese healthy blood donors. Serum albumin was found to be significantly lower in patients with hepatosplenic schistosomiasis (median = 37 g/l) than in controls (median = 47 g/l). Serum enzyme analysis revealed only minimal alterations of cellular enzyme activities, but a marked decrease of cholinesterase activity. Serum albumin concentration correlated significantly with cholinesterase activity. We conclude that liver function in patients with schistosomiasis and portal hypertension is partially disturbed. Low serum albumin and low cholinesterase activity reflected an impaired protein synthesis of the liver. Destruction of parenchymal liver cells was mild or absent.
