Life threatening parvovirus B19 and herpes simplex virus associated acute myocardial dysfunction in a child with homozygous sickle cell disease.

Human parvovirus (HPV) B19, a common infection, frequently causes transient red cell aplasia in children with hemolytic anemia, such as sickle cell disease (SCD). It was considered to be a self-limited condition, easily treated with blood transfusion. However, acute splenic sequestration, acute chest syndrome, nephrotic syndrome, and stroke have been reported in SCD patients following HPV B19 infection. We report a 3-year-old child with SCD who developed fulminant myocarditis following HPV B19-related aplastic crisis. The diagnosis of myocarditis should be considered in a patient with hemolytic anemia with an infection with HPV B19 who develops signs of cardiopulmonary failure despite correction of anemia.
