Glutamine study in hepatic schistosomiasis and effect of conventional medical therapy.

The liver plays a major role in urea and glutamine metabolism where it maintains ammonia and bicarbonate homeostasis under physiological and pathological conditions. Glutamine assessment in different liver diseases showed deviations from normal serum values. In the present study, glutamine level in serum [serum glutamate values] (SGV) and liver tissue homogenates (liver homogenate glutamine values] (LHGV) in patients with schistosomal hepatic fibrosis with and without conventional supportive medical therapy and anti-schistosomal therapy were correlated. LHGV in liver tissue homogenates from cases were higher than those of matched controls. SGV of patients with late hepatic schistosomiasis were greater than those with early stages of the disease. All patients, whether in early or late schistosomal hepatic fibrosis, showed reduction of SGV after treatment. We came to the conclusion that in patients with schistosomal hepatic fibrosis, whether early or late, there is a derangement of glutamine metabolism which could be corrected partially by the conventional supportive medical therapy. Again, estimation of glutamine in serum could be considered an early and reliable parameter for the assessment of liver function in patients with schistosomal hepatic fibrosis.
