Summary A 23 year-old man developed thrombocytopenic purpura at the end of the second week of the clinical evolution of hepatitis A confirmed by viral markers. The bone marrow of this patient showed megakaryocytic hyperplasia. Circulating in his serum immune complexes were demonstrated by solid phase conglutinin enzymo-immunoassay. Platelet-reactive serum factors were also detected by an indirect immunofluorescence test using fresh donor platelets as targets. The evolution of both the hepatitis and the purpura were benign with no therapy other than bedrest. Platelet count normalized within five weeks of the onset of purpura, and IgM antibodies against hepatitis A virus as well as circulating immune complexes dropped to normal levels. It is postulated that the thrombocytopenia of this case was caused by nonspecific deposition of immune complexes at the platelet surface.
