TLDR
Profiles of drug resistance suggest that a second-line treatment regimen based on protease inhibitors, with a backbone of nucleoside reverse transcriptase inhibitor, is a reasonable option for patients with HIV in sub-Saharan Africa who experience first- line treatment failure.Abstract:
Following large-scale roll-out of antiretroviral therapy in sub-Saharan Africa, the non-clinical efficacy of antiretroviral therapy has received little attention. We aimed to systematically review virological efficacy and drug-resistance outcomes of programmes of antiretroviral therapy in sub-Saharan Africa. 89 studies with heterogeneous design, definitions, and methods were identified. Overall, in on-treatment analysis, 10 351 (78%) of 13 288 patients showed virological suppression after 6 months of antiretroviral therapy, 7413 (76%) of 9794 after 12 months, and 3840 (67%) of 5690 after 24 months. Long-term virological data are scarce. Genotyping results were available for patients with virological failure (HIV-1 RNA greater than 1000 copies per mL). Most patients (839 of 849; 99%) were infected with a non-B HIV-1 subtype. However, drug-resistance patterns were largely similar to those in subtype B. Resistance profiles were associated with the antiretroviral drugs commonly used: the lamivudine-associated M184V mutation was most common, followed by K103N which is associated with non-nucleoside reverse transcriptase inhibitors. Thymidine-analogue mutations and the K65R mutation were less common. First-line antiretroviral therapy regimens used in sub-Saharan Africa are effective. Profiles of drug resistance suggest that a second-line treatment regimen based on protease inhibitors, with a backbone of nucleoside reverse transcriptase inhibitors, is a reasonable option for patients with HIV in sub-Saharan Africa who experience first-line treatment failure.read more

TL;DR: A strategic investment framework is proposed that is intended to support better management of national and international HIV/AIDS responses than exists with the present system and would avert 12·2 million new HIV infections and 7·4 million deaths from AIDS between 2011 and 2020.

TL;DR: It is suggested that a single allogeneic HSCT with homozygous CCR5Δ32 donor cells may be sufficient to achieve HIV-1 remission with reduced intensity conditioning and no irradiation, and the findings provide further support for the development of HIV- 1 remission strategies based on preventing CCR 5 expression.

TL;DR: In this article, the authors compared the predictions of several mathematical models simulating the same ART intervention programmes to determine the extent to which models agree about the epidemiological impact of expanded ART.

TL;DR: A significant increase in prevalence of drug resistance over time since antiretroviral rollout in regions of sub-Saharan Africa is suggested; this rise is driven by NNRTI resistance in studies from east and southern Africa.

TL;DR: Diosis was the greatest break point globally, but the most frequent key break point for individual countries was providing ART to those diagnosed, and large disparities were identified between countries.

Pharmacy Refill Adherence Compared with CD4 Count Changes for Monitoring HIV-Infected Adults on Antiretroviral Therapy

TL;DR: Pharmacy refill adherence assessments were as accurate as CD4 counts for detecting current virologic failure in this cohort of patients on cART and have the potential to predict virology failure before it occurs, indicating the potential utility of adherence assessments for predicting future, rather than simply detecting current, virolic failure.
