Abstract

In this editorial we comment on the article published in the recent issue of the World Journal of Gastroenterology. We focus specifically on the problem of occult hepatitis B virus (HBV) infection, that is a result of previous hepatitis B (PHB) and a source for reactivation of HBV. The prevalence of PHB is underestimated due to the lack of population testing programs. However, this condition not only complicate anticancer treatment, but may be responsible for the development of other diseases, like cancer or autoimmune disorders. Here we unveil possible mechanisms responsible for realization of these processes and suggest practical approaches for diagnosis and treatment.

Keywords: Occult hepatitis B virus infection, Hepatitis B virus reactivation, Previous hepatitis B, Cancer, Autoimmune disorders

Core Tip: Occult hepatitis B virus (HBV) infection is a result of previous hepatitis B (PHB) and source for reactivation of HBV. This may be a challenge when anti-cancer treatment is provided. However, PHB is a reason of other disorders, like cancer and autoimmune disorders development. We discuss this multifaceted problem from the viewpoint of pathogenetic mechanisms, and possible practical approaches.
