ABSTRACT
OBJECTIVE: Report on the early outcomes achieved in the prevention of mother-to-child transmission (PMTCT) programme in the Djoungolo Health District using more effective antiretroviral PMTCT regimens. METHODS: Observational cohort of HIV exposed infants. MAIN OUTCOME MEASURE: early infant HIV status and 3-month mortality rate. RESULTS: From March 2008 to March 2010, 587 HIV-positive mother-baby pairs were enrolled and classified according to the following maternal antiretroviral regimen: Group 1: highly active antiretroviral therapy (HAART), Group 2: dual therapy, Group 3: no treatment. 484/587 (82%) underwent HIV-early infant diagnosis at a median age of 7 weeks; 4.5% (95% CI 2.65-6.34) were HIV-infected. HIV transmission rate differed by maternal prophylaxis: 1.7% for HAART, 2.7% for dual therapy and 15.7% for Group 3 (p < 0.001), but not by feeding method (2.74%)-exclusive breastfeeding vs. 5.34% formula (NS). The 3-month mortality rate stands at 1%. CONCLUSIONS: The 4.5% MTCT-rate of HIV-1 reported, confirms the feasibility and effectiveness of a district wide PMTCT programme using HAART in low-income settings.

INTRODUCTION: The objective of the study was to determine HIV-1 RNA load profile during pregnancy and assess the eligibility for the maternal triple antiretroviral prophylaxis. It was an observational cohort of pregnant HIV positive women ignorant of antiretroviral therapy with CD4 cell count of > 350/mm(3) METHODS: Routine CD4 cell count assessment in HIV positive pregnant women completed by non exclusive measurement of the viral load by PCR /ARN in those with CD4 cell count > 350/mm(3). EXCLUSION CRITERIA: highly active antiretroviral therapy prior to pregnancy. RESULTS: Between January and December 2010, CD4 cell count was systematically performed in all pregnant women diagnosed as HIV-infected (n=266) in a referral center of 25 antenatal clinics. 63% (N=170) had CD4 cell count > 350/mm(3), median: 528 (IQR: 421-625). 145 underwent measurement of viral load by PCR/RNA at a median gestational of 23 weeks of pregnancy (IQR: 19-28). Median viral load 4.4 log(10)/ml, IQR (3.5-4.9).19/145(13%) had an undetectable viral load of = 1.8 log(10)/ml. 89/145(61%) had a viral load of = 4 log(10)/ml and were eligible for maternal triple ARV prophylaxis. CONCLUSION: More than 6 in 10 pregnant HIV positive women with CD4 cell count of > 350/mm(3) may require triple antiretroviral for prophylaxis of MTCT. Regardless of cost, such results are conclusive and may be considered in HIV high burden countries for universal access to triple antiretroviral prophylaxis in order to move towards virtual elimination of HIV MTCT.
