Spontaneous resolution of hemophagocytic syndrome associated with acute parvovirus b19 infection and concomitant epstein-barr virus reactivation in an otherwise healthy adult.

摘要

Reported here is the case of a patient who spontaneously recovered from hemophagocytic syndrome associated with acute B19 infection and concomitant Epstein-Barr virus reactivation. The previously healthy 37-year-old-man was hospitalized after 10 days of high fever, arthralgia and arthritis and was determined to have hemophagocytic syndrome. Immunoglobulin (Ig) M antibodies to Epstein-Barr virus (EBV) capsid antigen, early antigen and parvovirus B19 (B19) were found. B19 DNA and low-level EBV DNA were detected in bone marrow, serum and peripheral blood mononuclear cells. The patient recovered spontaneously without any treatment. Two months later anti-B19 IgG antibodies were detected, while at 9-month follow-up, anti-B19 IgM antibodies were no longer detectable and B19 DNA had disappeared from serum. To the best of our knowledge, this is the first report of spontaneous resolution of hemophagocytic syndrome associated with acute B19 infection and concomitant EBV reactivation in an otherwise healthy adult.
