HIV RNA monitoring is not available in most antiretroviral treatment (ART) programs in sub-Saharan Africa; switch to second-line therapy is mostly guided by clinical/immunological criteria. This may lead to unnecessary disease progression and drug resistance accumulation. We investigated the prognostic value of virological and immunological status 6 months after ART initiation with respect to death, loss to follow-up, and treatment switch.We considered treatment-naive HIV-1-infected patients, starting ART with available 6-month visit and subsequent follow-up, enrolled in a prospective cohort comprising 5 ART sites in 3 sub-Saharan countries. Outcome measures included the time from 6-month visit to death for all causes, loss to follow-up, and switch to second line.Of 2539 patients, 62% were females, their median pre-ART CD4 count was 215 cells per microliter, median HIV RNA 4.6 Log10 copies per milliliter, 30% were on WHO stage 3/4. At 6 months, 85% had HIV RNA <1000 copies per milliliter. During 3112 person-years follow-up after the 6-month visit, 91 patients died. Death was predicted by 6-month HIV RNA ≥10,000 copies per milliliter, adherence, and 6-month CD4 <200 cells per microliter. The 2-year estimated probability of surviving ranged from 0.69 (with 6-month HIV RNA ≥10,000 and CD4 <200) to 0.95 (with HIV RNA <1000 and CD4 ≥200). Loss to follow-up (1.95 per 100 person-years follow-up) was predicted by the 6-month HIV RNA >10,000 copies per milliliter and adherence but not by CD4. Switch to second line (6.94 per 100 person-years follow-up) was predicted by 6-month HIV RNA and CD4.In patients starting ART in sub-Saharan Africa, 6-month HIV RNA independently predicts subsequent survival, retention to care, and switch to second-line therapy. This measure warrants further evaluation as specific time point monitoring option. [ABSTRACT FROM AUTHOR]

We evaluated 70 HIV-infected pregnant women with CD4+ cell count >350 cells per cubic millimeter who received zidovudine, lamivudine, and nevirapine from week 25 of gestation until 6 months after delivery and a 3-week tail of zidovudine and lamivudine at the moment of drug discontinuation. Forty days after the interruption of all drugs resistance mutations were present in 5 of 70 (7.1%) women. Two of them had the same mutation archived in baseline HIV DNA. The other 3 women had, at least once, detectable viral load and presence of mutations during treatment. Overall, the risk of developing resistance mutations in compliant women was low.

The article presents a study which aims to conduct an assessment of the cost-effectiveness of using highly active antiretroviral therapy (HAART) in prevention of mother-to-child transmission (PMTCT) in Malawi. The cost-effectiveness of a PMTCT program implemented at Drug Resource Enhancement against Aids and Malnutrition-Project Malawi (DREAM-PM) health centres was analyzed. Results of the study showed the cost-effectiveness of using of HAART in a PMTCT programme in resource-limited settings.

The article examines how administering antiretroviral drugs during the last trimester of pregnancy and around the time of delivery can be effective in the reduction of HIV transmission from mother to child. The research indicates that treatment with highly active antiretroviral therapy (HAART) results in plasma concentrations in breast milk that can reduce HIV RNA levels significantly.
