Abstract

In the 21st century, there was a significant breakthrough in the treatment of many neoplasms, autoimmune diseases and chronic inflammations due to the introduction of monoclonal antibodies into therapeutic regimens. Among them, some of the most frequently used are anti-TNF and anti-CD20 antibodies. Particularly related to the latter is the issue of reactivation of HBV infection, which can lead to fulminant inflammation and liver failure, and in some cases even death of the patient. Nevertheless, physicians who use the above-mentioned medicines have diagnostic tools at their disposal to determine the status of HBV infection, as well as vaccinations and drugs that can be used to minimize the risk of HBV reactivation with all its consequences. In this paper, I present the basic aspects of HBV infection that every doctor dealing with anti-CD20 therapy should know, as well as the procedures for dealing with a patient qualified for such therapy.
