[24 cases of human parvovirus B19 infection in children].
From January 1, 1987 through December 31, 1990, twenty-four pediatric patients with human parvovirus B19 (HPV B19) infection were seen. In every case the diagnosis was established by a positive capture immunoassay for IgM antibodies against the HPV B19. Four patients had hematologic manifestations, including one case of transient bone marrow aplasia revealing hereditary spherocytosis, one case of autoimmune hemolytic anemia with beta-thalassemia, and two cases of peripheral thrombocytopenia. Eight patients had skin lesions, with a morbilliform rash in six cases, erythema nodosum in one case, and Gianotti-Crosti syndrome in one case. No patients had erythema infectiosum. Seven patients developed joint manifestations: Henoch-Schönlein purpura in two cases, arthralgia in four cases, and polyarticular disease progressing to severe rheumatoid arthritis in a thirteen-year-old girl. Unremarkable symptoms of viral disease were seen in three patients. A five-month-old infant developed severe acute myocarditis. One patient with hepatitis A had acute liver failure. This study confirms the broad spectrum of clinical manifestations of HPV B19 infection. There were a number of unusual findings, including the high rate of joint manifestations (29%) and the severe course of some hematologic and myocardial manifestations. These results raise the question of whether the HPV B19 may be involved in the genesis of chronic juvenile arthritis.
