A Case of Hepatitis B Virus Reactivation Triggered by Acute Epstein-Barr Virus Infection.

Reactivation ofHepatitis B virus (HBV) is not an uncommon condition. It is known to occur with immunosuppressive therapy. There are several viral infections that can trigger HBV reactivation, such as human immunodeficiency virus (HIV) infection. However, there is no reported case of HBV reactivation triggered by Epstein-Barr virus (EBV) infection in the literature. To our knowledge, we report the first case of reactivation of HBV secondary to acute Epstein-Barr virus (EBV) infection in the literature. A 47-year-old Caucasian male with a remote history of resolved acute Hepatitis B virus infection presented to our hospital with severe acute hepatitis, which manifested as epigastric pain, jaundice, dark urine, light-colored stools, hyperbilirubinemia, and transaminitis in the 1000s. Ultimately, the patient was diagnosed with reactivation of HBV triggered by acute EBV infection. After several days of supportive treatment, his hepatic function normalized. He was discharged with a scheduled follow-up at a hepatology clinic. In conclusion, EBV infection should be suspected as a trigger in cases with HBV reactivation, particularly when common etiologies are excluded.
