Abstract
Symptoms caused by acute human parvovirus B19 (HPV-B19) infection can vary considerably, from asymptomatic to severely symptomatic. A 39-year-old Japanese woman complained of sudden, severe arthralgia with edematous limbs coincident with an outbreak of HPV-B19 infection at the elementary school attended by her daughter. A diagnosis of acute HPV-B19 infection was made by the detection of serum antibody to HPV-B19 IgM and HPV-B19 DNA. Magnetic resonance imaging revealed bilateral synovitis of the cubital joints. The patient was immunocompetent and suffered from severe arthralgia associated with persistent HPV-B19 viremia for more than 4 months after the diagnosis of acute HPV-B19 infection. The administration of high-dose intravenous immunoglobulin resulted in remission, with little change in the serum HPV-B19 DNA level. Even in our immunocompetent patient, severe and prolonged arthritis was found to be associated with persistent viremia.
