Vasoactive intestinal peptide (VIP) exerts a broad range of biologic actions that may include modulation of hepatic granuloma formation. This study aimed to investigate the effect of VIP administration on the course of acute murine schistosomiasis mansoni. Mice were infected each with 40 Schistosoma (S.) mansoni cercariae and injected intraperitoneally with VIP at a total dose of 1mug/kg body weight. VIP treatment was very effective in diminishing worm fecundity, hepatic granuloma size and number by about 54%, 75% and 51%, respectively, and reducing liver collagen content. Serum level of interleukin (IL)-10 was increased, while level of IL-12 and tumor necrosis factor (TNF)-alpha were decreased as a result of VIP administration. Carbohydrate antigen 19.9 (CA 19.9) induced by S. mansoni infection was decreased with VIP treatment. Activities of hepatic gamma-glutamyl transferase (gamma-GT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in liver tissue homogenate of infected treated mice were increased. These results indicate that suitable administration of exogenous VIP can be effective in ameliorating immunopathologic damage associated with schistosomiasis.
