[Primary infection with Epstein-Barr virus in a 77-year-old patient with B symptoms and hepatitis -- a case report]. / 77-jähriger Patient mit Epstein-Barr-Virus-Erstinfektion mit B-Symptomatik und Hepatitis -- ein Fallbericht.

Epstein-Barr virus (EBV) infection has a prevalence of 90 % and is - depending on the immune status of the host - associated with a broad spectrum of clinical manifestations. By presenting a case report we would like to demonstrate an unusual clinical course of a primary infection with EBV in an elderly patient. A 77-year-old patient was admitted to hospital in reduced health condition because of a persisting bronchopulmonary infection with B symptoms. The patient had already been treated with antibiotics. Because of elevated liver enzymes, a liver biopsy was performed. Histopathology revealed moderate acute hepatitis with cholangitis und endothelialitis, pointing to an EBV-induced hepatitis. Serological examinations confirmed the diagnosis, revealing a primary infection with positive EBV VCA IgM and IgG. EBV PCR of the liver tissue was positive, viral genome could be demonstrated within lymphocytes. A short period later the patient was discharged to reconvalescence. This case report demonstrates an unusual primary infection with EBV at the age of 77 with atypical clinical symptoms and hepatitis. The relevance of EBV in the differential diagnosis of atypical infectious diseases with hepatitis of unknown aetiology is strengthened on taking data reports from the literature into consideration.
