THE EXPERIENCE IN THE APPLICATION OF NIKAVIR IN THE SCHEMES OF PERINATAL CHEMOPROPHYLACTICS OF HIV INFECTION: EVALUATION OF THE IMMUNOLOGICAL AND VIRUSOLOGICAL EFFECTIVENESS

Abstract

Objective. The goal of this work was to study the immunological and virological efficacy of the domestic antiretroviral drug nicavir (at the optimal dose, as proven by previous clinical studies) with lamivudine, in comparison with other drugs of the group of nucleoside reverse transcriptase inhibitors in combination with kaletra in perinatal HIV chemoprophylaxis regimens. Methods. 658 pregnant women aged 16-39 years and children born to them were examined. The first group (281 people) and the third group (66 people) received the nicavir (manufactured by AZT PHARMA KB LLC) with lamivudine in combination with calyx; the second (281 people) and the fourth (30 people) of the comparison group, stag and zidovudine, respectively, with lamivudine in combination with calyx. The effectiveness of CP was assessed from the increase in the number of CD4 lymphocytes, reduction of the viral load, and the number of children born without HIV DNA in the blood. Results. Against the backdrop of the therapy, the viral load below the detectable level and the positive dynamics of CD4 lymphocytes were registered in all examined women prior to childbirth. When applying the scheme of niacavir + lamivudine + kaletra, a more rapid decrease in the level of BH, most pronounced by week 4 of therapy, was found, as compared with the rate of decline of the same index in pregnant comparison groups. Conclusions. The obtained results allow us to consider ART with the inclusion of nicavir effective and recommend its priority use in perinatal prevention of mother-to-child transmission of HIV.
