Background: Parvovirus B19 infection is associated with a variety of symptoms like erythema infectiosum, anaemia and arthritis. In immunocompetent persons, viraemia is usually cleared a few weeks after infection. Objective: An immmunocompromised adult female patient was persistently infected with B 19 after allogenic bone marrow transplantation (BMT) and developed chronic anaemia. Study design: B19-specific antibodies were determined by ELISA and viral load was assessed using a quantitative real time B 19 PCR. The patient was evaluated clinically. Results: Two years after successful BMT, the patient received intensified immunosuppressive treatment, erythropoetin and erythrocyte concentrates due to chronic graft-versus-host disease with renal failure. Despite of this treatment, the aplastic anaemia worsened. PCR revealed B19 viraemia with 10(12) geq/ml serum. After 7 months of repeated applications of immunoglobulins and reduction of immunosuppressive treatment, reticulocyte counts and haemoglobin levels normalized and the viral load finally dropped to 103 geq/ml serum. One of the back-up samples of the erythrocyte concentrates tested positive, the respective transfusion had been applied 2 months after the beginning of viraemia. Conclusions: The source of the primary infection remained unclear, but at least re-infection by blood transfusion is likely. Treatment did not result in virus elimination from peripheral blood but in resolvement of symptoms. (C) 2004 Elsevier B.V. All rights reserved.
