BACKGROUND: Secondary or reactive hemophagocytic syndrome is frequently related to viral infections and is named Virus-Associated Hemophagocytic Syndrome (VAHS). Cytomegalovirus (CMV) has been associated with hemophagocytic syndrome in healthy subjects, patients with inflammatory bowel diseases rheumatologic diseases, and transplant recipients. CMV and hepatitis B virus (HBV) can be sexually transmitted. However, co-infection with these viruses has never been reported and the clinical follow-up after acute HBV-CMV infection is not known. OBJECTIVES: To report on the first case of a VAHS related to acute CMV and HBV co-infection probably acquired after sexual contact. STUDY DESIGN: A 47-year-old woman, with no past medical history, complaining of severe asthenia, pneumonia, myalgia, and high fever, was hospitalized for the first time on July 5, 2008. During 20 days, her CMV viral load and HBV DNA were monitored. RESULTS: Ten days after her hospitalization, all signs and symptoms worsened. Twenty days after hospitalization, the patient had a natural recovery from acute HBV infection and a rapid clearance of CMV infection. Three weeks later, the patient was discharged without any complaints. CONCLUSION: This report points out the etiological role of CMV and HBV co-infection in VAHS due to probable sexual transmission.
