title: Interactions between mefloquine and the anti-fibrotic drug silymarin on Schistosoma mansoni infections in mice.
abstract: The present study tests the anti-inflammatory and anti-fibrotic effects of silymarin alone or combined with mefloquine on acute schistosomiasis by evaluating parasitological, histopathological, biochemical and immunological parameters. Male CDI Swiss mice were divided into seven groups, which included healthy controls, mice infected with Schistosoma mansoni or treated with silymarin (140 mg/kg body weight) or mefloquine (400 mg/kg body weight), or mice treated with a combination of both drugs and uninfected mice simply treated with mefloquine or silymarin alone. All mouse groups were sacrificed 8 weeks post-infection (pi) and/or post-treatment. Those infected mice treated with both silymarin and mefloquine showed a significant decrease (P <  0.001) in worm burden, immunoglobulins (IgG and IgM), liver function enzymes and granuloma diameter, with complete eradication of immature and mature eggs. In conclusion, treatment with silymarin combined with mefloquine in murine schistosomiasis was able to reduce granulomatous reactions and hepatic fibrosis. Hence, this combination is a new strategy to be studied as an efficient tool in the treatment of schistosomal liver fibrosis.
