Abstract

Introduction: Parvovirus B19 infection generally presents as a transient viral illness in children but rarely shows systemic lupus erythematosus-like symptoms.

Case report: Here we present a 7-year-old girl with parvovirus B19 infection who had prolonged fever, rash, pancytopenia and hypocomplementemia making it difficult do differentiate from the first episode of systemic lupus erythematosus. Because she had severe progressive pancytopenia she was administered intravenous immune globulin treatment and her clinical course was dramatically improved.

Discussion: Parvovirus B19 infection can mimic systemic lupus erythematosus and it may be difficult to differentiate a recent parvovirus B19 infection and the first presentation of systemic lupus erythematosus. Absence of discoid lesions, alopecia, Raynaud phenomenon and autoimmune hemolytic anemia may help to distinguish parvovirus B19 infection from systemic lupus erythematosus.

Conclusions: Parvovirus B19 infection may cause a severe clinical picture resembling systemic lupus erythematosus even in otherwise healthy children. Intravenous immune globulin treatment might be considered in cases resistant to supportive management.

Keywords: Parvovirus B19; children; systemic lupus erythematosus.
