A New Methodological Approach to the Evaluation of the Course and Conduct of Therapy Patients Co-infected with Human Immunodeficiency Virus and Hepatitis C Virus

Coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) is one of the most common pathological conditions worldwide. Liver disease is a major cause of death for these patients. We attempted to determine whether the order of HIV and HCV acquisition is important for the progression of liver fibrosis. In was shown that in patients younger than 35, the order of HIV and HCV acquisition has a crucial role in this process. In particular, the patients who acquired HIV as the first pathogen are at higher risk of progressive liver fibrosis and have higher HIV viral load and lower CD3(+)CD4(+) cell count

MECHANISMS OF INTERACTION OF VIRAL CAUSATIVE AGENTS IN PATIENTS CO-INFECTED WITH HUMAN IMMUNODEFICIENCY AND HEPATITIS C VIRUSES

In patients infected with human immunodeficiency virus (HIV) in 20 - 30% of cases co-infection with hepatitis C virus (HCV) is observed, that is associated with common routes of transmission for these causative agents. The main cause of lethal outcome for co-infected patients is liver damage. Thus, analysis of mechanisms of mutual influence of HIV and HCV under the conditions of co-infection gains special attention, that can be examined from both standpoints of direct inter-molecular interaction of 2 viral causative agents, as well as from the position of their immune-mediated effect. Negative effect of HIV on the course of fibrosis process in liver during HCVinfection is associated with the feature of this virus to cause deep alteration in the immune system by direct damage of CD4+ cells, disruption of mechanisms of immunological memory, suppression of functions of liver fraction of NK and NKT, as well as its ability of co-receptor interaction with hepatocytes and stellate cells, enhancing progress of fibrosis alterations and HCV replication in liver. HCV is also established to effect replication of HIV, stimulate infection of macrophages with this virus. All these events facilitate the rise in lethality during HIV and HCV co-infection
