PREVALENCE AND MOLECULAR GENETIC PECULIARITIES OF PARENTERAL VIRAL HEPATITIS B AND C AMONG HIVPOSITIVE CITIZENS OF THE FAR EASTERN FEDERAL DISTRICT, INCLUDING THOSE PERSONS SENTENCED TO DEPRIVATION OF FREEDOM

We conducted a comparative analysis of the parenteral viral hepatitis B and C (HBV and HCV) prevalence and their molecular genetic characteristics among prisoners of persons diagnosed with HIV infection (41 samples), HIV-positive free citizens (187 samples) and «conditionally healthy population» with the lack of information about the presence of a diagnosis of chronic viral hepatitis of any etiology and HIV infection (231 samples). Immunological and molecular biological research methods were used. Obtained data analysis showed that the prevalence of infection markers with viruses of parenteral hepatitis was significantly higher in the groups of HIV-positive individuals (imprisoned and freemen). The HBsAg-negative form of the disease was determined among the HIV-positive free population and in the «conditionally healthy population». Over the past 10 years (2009–2018), the proportion of HIV-positive prisoners in custody of people with HCV monoinfection doubled, HBV was increased in 8.7 times. Significant decrease in the combined infection of HBV and HCV of this contingent was found. Given this decrease in the penitentiary system in HIV-positive individuals, the overall burden of HBV infection (both in mono form and coinfection with HCV) significantly (5.3 times) decreased , which can be attributed to successful widespread vaccination against hepatitis B in Russia. The most common HCV genotypes among HIV-positive individuals were 1b and 3a, genotypic structure of HBV prevailed genotype D.
