title: Hemolysis and autoantibodies to triosephosphate isomerase in a patient with acute hepatitis A virus infection.
abstract: Having returned from a holiday in Southeast Europe, a 30-year-old German woman developed acute hepatitis. Hepatitis A virus (HAV) infection was diagnosed serologically. During the course of the infection, hemolysis was found. IgM antibodies against triosephosphate isomerase (IgM anti-TPI) were detected in the patient's serum from the acute phase of the HAV infection. Affinity purified IgM anti-TPI from the serum reduced the enzyme activity in vitro and caused an increased 51Cr release from erythrocytes. IgM anti-TPI is assumed to be one of the causative agents of hemolysis in HAV infection.
