The Influence of Short-term Starvation on Hepatitis B Virus Load

February 10, 2015 updated by: AMIR SHLOMAI, Rabin Medical Center

The Influence of Short-term Starvation on Disease Severity and Viral Replication Among Hepatitis B Virus Patients

Hepatitis B virus is a small DNA virus that affects 400 million people worldwide. The virus infects the liver and previous studies, done in tissue culture and in animals, have shown that viral replication is affected by metabolic changes occurring in the liver. Specifically, starvation induces HBV gene expression and replication, in parallel to the activation of the gluconeogenesis response, and feeding attenuates viral activity. In this study we are going to recruit HBV patients with detectable viremia and analyze their viral load after an over night starvation versus after a morning meal. Our hypothesis is that following an over-night starvation viral load will be higher than that in the fed state.
