Helicobacter pylori in liver diseases

At the present stage of knowledge, the participation of the Helicobacter bacteria in the pathology of liver and the bile tract in humans has not been univocally documented. However, apparent are the premises so as to go on performing the examinations under discussion since the said participation cannot be excluded. If the more direct evidence of the etiologic role of the Helicobacter in the pathology of liver were available, it would create the chances for the more effective treatment of patients than the case has been so far. Cancer commonly derives from the chronic inflammation and infection and in case of hepatocellular carcinoma (HCC), may arise either from local liver derived progenitor cells (LPCs) or bone marrow originated stem cells (BMSCs) and future studies should disclose the role of either type of cells and of inflammatory factors such as generated by Helicobacter infection in the liver pathophysiology.
