[A case of vivax malaria with thrombocytopenia suggesting immunological mechanisms].

Recently, it has been shown that the thrombocytopenia that complicates some malarial infections is caused by immune mechanisms. We report a case of malaria associated with thrombocytopenia and increased platelet-associated IgG (PAIgG). In this case, anti-malarial therapy reduced the level of PAIgG to normal levels in association with normalization of the platelet count. This case suggests the immunological mechanisms of thrombocytopenia in malaria.
