Lives saved by expanding HIV treatment availability in resource-limited settings: the example of Haiti.

ABSTRACT: BACKGROUND:Guidelines recommend antiretroviral therapy (ART) initiation at CD4 <350 cells per microliter for HIV-infected individuals in resource-limited settings. However, funding for treatment expansion remains uncertain. We forecast the mortality impact of ART expansion alternatives in Haiti. METHODS:We used data from Haiti to develop a country-specific model of HIV disease. The model projects the mortality, total number of HIV-infected individuals, and number and coverage (percentage of those eligible) on ART by simulating cohorts of HIV-infected individuals over 10 years. Five ART expansion scenarios, ranging from fully expanded ART (best case) to No New ART (worst case), were assessed. RESULTS:By 2010, the model predicts 103,500 individuals living with HIV in Haiti, of whom 27,300 were estimated to receive ART. Continuing ART initiation at current rates requires increasing the number on ART to 43,300 by 2020 (56% coverage), with 89,700 deaths estimated between 2010 and 2020. The number on ART could increase by 7400 (+17.1%, best case) or decrease by 25,600 (-59.1%, worst case), resulting in 19,500 deaths averted and 9900 fewer in care awaiting ART (best versus worst case). Results are sensitive to untreated disease progression and pre-ART loss from care. Increased HIV testing, linkage to care, and retention in care can avert additional deaths and achieve nearly 80% ART coverage with optimal policy improvements. CONCLUSIONS:In resource-limited settings, continued improvements in HIV treatment access will save lives. Efforts to efficiently expand ART access should remain a global priority.

Project description:IntroductionLipodystrophy is a term used to describe a metabolic complication of fat loss, fat gain, or a combination of fat loss and gain, which is associated with some antiretroviral (ARV) therapies given to HIV-infected individuals. There is limited research on lipodystrophy in low- and middle-income countries, despite accounting for more than 95% of the burden of HIV/AIDS. The objective of this review was to evaluate the prevalence, pathogenesis and prognosis of HIV-related lipoatrophy, lipohypertrophy and mixed syndrome, to inform clinical management in resource-limited settings.MethodsWe conducted a structured literature search using MEDLINE electronic databases. Relevant MeSH terms were used to identify published human studies on HIV and lipoatrophy, lipohypertrophy, or mixed syndrome in low-, low-middle- and upper-middle-income countries through 31 March 2014. The search resulted in 5296 articles; after 1599 studies were excluded (958 reviews, 641 non-human), 3697 studies were extracted for further review. After excluding studies conducted in high-income settings (n=2808), and studies that did not meet inclusion criteria (n = 799), 90 studies were included in this review.Results and discussionOf the 90 studies included in this review, only six were from low-income countries and eight were from lower middle-income economies. These studies focused on lipodystrophy prevalence, risk factors and side effects of antiretroviral therapy (ART). In most studies, lipodystrophy developed after the first six months of therapy, particularly with the use of stavudine. Lipodystrophy is associated with increased risk of cardiometabolic complications. This is disconcerting and anticipated to increase, given the rapid scale-up of ART worldwide, the increasing number and lifespan of HIV-infected patients on long-term therapy, and the emergence of obesity and non-communicable diseases in settings with extensive HIV burden.ConclusionsLipodystrophy is common in resource-limited settings, and has considerable implications for risk of metabolic diseases, quality of life and adherence. Comprehensive evidence-based interventions are urgently needed to reduce the burden of HIV and lipodystrophy, and inform clinical management in resource-limited settings.
