Many things can reactivate chronic hepatitis B virus (HBV) infection—withdrawal of antiviral therapy, pregnancy, and chemotherapy, to name a few. So when a patient with stable chronic HBV virus presented with significant hepatitis flare, clinicians from Beth Israel Deaconess Medical Center in Boston, Massachusetts, had a long list to check.
They first ruled out drug-associated hepatotoxicity and screened the patient for common causes of acute hepatitis. Beyond the HBV, the patient did not have other significant medical conditions, had not had close contact with anyone ill, and was not pregnant. Tests were negative for cytomegalovirus, Epstein-Barr syndrome, HIV, hepatitis A, C, and D. The patient tested negative for both antihepatitis E virus (HEV) IgM and IgG in a visit about 9 months before.

However, she reported regularly consuming pork, including a recent barbecue meal. Thus, the clinicians focused on HEV serology, which confirmed that she had an acute HEV infection.
Pigs act as a “natural reservoir” for HEV; contaminated meats and direct contact with animals are the most common causes of HEV human infection in industrialized countries. Recent data reveal the prevalence of HEV antibodies in the US is about 6%, illustrating that it is not as uncommon as it was thought to be. Although there was no direct evidence to confirm the source of her infection, it seemed likely due to the pork consumption.
The patient was started on tenofovir but stopped it 4 months later because she felt well. After a subsequent flare, “repeated counseling” persuaded the patient to start on entecavir, with successful viral suppression.

Hepatitis E superinfection on chronic HBV can contribute to significant morbidity and mortality, the clinicians say, particularly in patients with cirrhosis. Concurrent infection with another viral hepatitis should be considered in both immunodeficient and immunocompetent patients with chronic HBV reactivation.
