BACKGROUND: During pregnancy and childbirth, anemia and thrombocytopenia are twice as common among HIV-positive women as in the general population. It has not been yet clear to what extent HIV affects the incidence of cytopenias, therefore, the correlation between the incidence and the HIV RNA level and CD4 count in HIV-positive pregnant women, as well as the role of antiretroviral therapy, requires further study. AIM: The aim of this study was to assess the effect of the HIV RNA level and CD4

... ount on the frequency of anemia and thrombocytopenia in HIV-positive pregnant women. MATERIALS AND METHODS: In this study, we analyzed social and demographic features, epidemiological personal history data, the frequency of pregnancy and delivery complications, and the timing of the initiation of antiretroviral therapy in 303 HIV-positive pregnant women, as well as the data of screening for HIV infection of their children. The study included 27 mother-child pairs with perinatal HIV transmission and 276 mother-child pairs without mother-to-child transmission of HIV. All pregnant women were divided into groups depending on the CD4 count and HIV RNA level. A comparative analysis of anemia and thrombocytopenia frequencies was carried out in the study groups. RESULTS: A direct correlation was revealed between the frequency of anemia and thrombocytopenia in HIV-positive pregnant women and markers of HIV infection: severe immunodeficiency (CD4 200 cells/l, p 0.01) and high HIV RNA levels (more than 100,000 copies / ml, p 0.01) in peripheral blood. CONCLUSIONS: We confirmed the high frequency of cytopenias in HIV-positive pregnant women, which exceeds the general population level. In addition, we demonstrated the effectiveness of prescribing antiretroviral therapy among women of reproductive age who planned to become pregnant or did not exclude the possibility of pregnancy (who did not use the effective methods of contraception), as a means of anemia and thrombocytopenia prevention during pregnancy.
