Transfusion transmission of hepatitis A virus with fecal shedding in a previously hepatitis A vaccinated recipient

Abstract

We describe a rare case of hepatitis A virus (HAV) replication in feces despite presence of hepatitis A antibodies in an acute myeloid leukemia (AML) patient after transfusion with HAV contaminated platelets. The patient has been vaccinated against HAV years before the AML diagnosis. Transient infection and reshedding should thus be considered in antibody-positive hematological patients. Transfusion associated HAV transmission is rare, and little evidence exists on the clinical consequences and possible effect of treatment with immunoglobulin. Further reporting on fecal shedding despite antibodies are needed, as HAV antibody levels are used as course of action for post-exposure prophylaxis and infection control.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
