RÉSUMÉ

Objective@#To calculate the number of pregnant women who receive standardized prevention of mother-to-child transmission (PMTCT) services for HIV annually.@*Methods@#HIV-positive pregnant women in six counties of Liangshan Prefecture in 2017 were selected as study subjects. The entire process, from when the subjects first received the PMTCT of HIV services to the end, was divided into four stages, which were further divided into 25 phases. The equivalent coefficient was used to indicate the weight of workload in each phase. Seven experts were invited to score the equivalent coefficient; the number of pregnant women who received standardized services to prevent the transmission of HIV was calculated.@*Results@#A total of 663 HIV-positive pregnant women were registered in six Liangshan Prefecture counties in 2017. This figure was converted into 7,780 person-months devoted to HIV-positive pregnant women, with 260 person-months (3.34%) spent on the first antenatal care, 1,510 person-months (19.41%) during pregnancy, 378 person-months (4.86%) on delivery, and 5,632 person-months (72.39%) on post-partum period. The equivalent coefficient calculation showed that 314 HIV-positive pregnant women received standardized PMTCT services.@*Conclusion@#The number of pregnant women receiving standardized services for the PMTCT of HIV can be calculated accurately using the equivalent method to identify the gap between the level of PMTCT of HIV intervention services needed and the actual workload.

RÉSUMÉ

<p><b>OBJECTIVE</b>To investigate HIV-1 co-receptor usage in patients experienced anti-retroviral therapy (ART) in Anhui and Henan province of China.</p><p><b>METHODS</b>A total of 45 HIV-1 infected individuals who have experienced ART and 109 un-experienced ART patients from Anhui and Henan province, which were called as treatment group and treatment-negative group, were selected as study subjects. HIV-1 strains were isolated from peripheral blood mononuclear cells of whole blood from patients. HIV-1 p24 in the culture supernatant was measured using a commercial enzyme-linked immunosorbent assay (ELISA) kit. HIV-1 co-receptor usage was identified using Ghost cell lines expressing CD4 and the chemokine receptor CCR5 or CXCR4.</p><p><b>RESULTS</b>Among 45 HIV strains from the treatment group, 22 (48.9%) strains used CCR5 as a co-receptor (R5 tropic strain), 21 (46.7%) strains used CXCR4/CCR5 as a co-receptor (X4/R5 duel tropic strain), and 2 (4.4%) used only CXCR4 as a co-receptor (X4 tropic strain). In 109 strains from treatment-negative group, 96 (88.1%) strains used CCR5 as a co-receptor (R5 tropic strain), 13 (11.9%) strains used CCR5/CXCR4 as a co-receptor use (X4/R5 strain). A significant difference was found between two groups in X4 co-receptor usages (χ(2) = 27.30, P < 0.05). Furthermore, after treated with AZT + DDI + NVP, the HIV-1 CXC4/CCR5 utilization was 59.09% (13/22), meanwhile after treated with D4T + DDI + NVP, the HIV-1 CXC4/CCR5 utilization was 43.48% (10/23), which the difference was not statistical significant (χ(2) = 1.10, P = 0.30).</p><p><b>CONCLUSION</b>HIV-1 CXCR4/CCR5 co-receptor utilization was higher in ART patients than treatment-negative patients.</p>
