The Clinical and Economic Impact of Attaining National HIV/AIDS Strategy Treatment Targets in the United States.

Background: The US National HIV/AIDS Strategy (NHAS) aims for 72% (90% diagnosed times 80% of those virally suppressed) viral suppression among persons with human immunodeficiency virus (HIV) by 2020. We examined the clinical and economic impact of reaching this target, in the general US population and among black men who have sex with men (MSM), the group with the highest HIV prevalence. Methods: Using a mathematical simulation, we project the 5- and 20-year clinical outcomes, costs, and incremental cost-effectiveness ratios for (1) Current Pace of detection, linkage, retention, and virologic suppression and (2) NHAS investments in expanded testing ($24-$74 per test) and adherence ($400 per person-year), calibrated to achieve 72% suppression by 2020. We examined alternative rates of testing, retention, and suppression and the efficacy and cost of adherence interventions. Results: Compared with Current Pace over 20 years, NHAS averted 280000 HIV transmissions (80000 in black MSM) and 199000 (45000) deaths and saved 2138000 (453000) years of life, while increasing costs by 23%. The incremental cost-effectiveness ratio for NHAS compared with Current Pace was $68900 per quality-adjusted life-year ($38300 for black MSM) and was most sensitive to antiretroviral therapy costs. Conclusions: Reaching NHAS targets would yield substantial clinical benefits and be cost-effective in both the general US and black MSM populations.

HIV, tuberculosis, and noncommunicable diseases: what is known about the costs, effects, and cost-effectiveness of integrated care?

Unprecedented investments in health systems in low- and middle-income countries (LMICs) have resulted in more than 8 million individuals on antiretroviral therapy. Such individuals experience dramatically increased survival but are increasingly at risk of developing common noncommunicable diseases (NCDs). Integrating clinical care for HIV, other infectious diseases, and NCDs could make health services more effective and provide greater value. Cost-effectiveness analysis is a method to evaluate the clinical benefits and costs associated with different health care interventions and offers guidance for prioritization of investments and scale-up, especially as resources are increasingly constrained. We first examine tuberculosis and HIV as 1 example of integrated care already successfully implemented in several LMICs; we then review the published literature regarding cervical cancer and depression as 2 examples of NCDs for which integrating care with HIV services could offer excellent value. Direct evidence of the benefits of integrated services generally remains scarce; however, data suggest that improved effectiveness and reduced costs may be attained by integrating additional services with existing HIV clinical care. Further investigation into clinical outcomes and costs of care for NCDs among people living with HIV in LMICs will help to prioritize specific health care services by contributing to an understanding of the affordability and implementation of an integrated approach.

High frequency of hypothalamic-pituitary-adrenal axis dysfunction after local corticosteroid injection in HIV-infected patients on protease inhibitor therapy.

BACKGROUND: The frequency of hypothalamic-pituitary-adrenal axis dysfunction among HIV-infected patients receiving steroid injections has not been reported, and the risk factors for this adverse event are poorly characterized. METHODS: We conducted a retrospective analysis of data from HIV-infected patients in the Partners HealthCare system (Boston, MA) who received corticosteroid injection(s) between 2002 and 2011. Chart review focused on HIV status, antiretroviral therapy [eg, protease inhibitors (PI)], steroid injection(s), and adrenal axis dysfunction (eg, adrenal insufficiency and/or Cushing syndrome). Because all cases occurred among patients on PIs, we performed additional detailed data extraction and conducted univariate and multivariate analyses to identify risk factors in this group. RESULTS: One hundred seventy-one HIV-infected patients received ≥1 corticosteroid injection(s) in the study period. Nine cases (event frequency: 5.3%; 95% confidence interval: 2.4% to 9.8%) of secondary adrenal insufficiency were diagnosed; 5 (55%) of these 9 patients also had clinical evidence of Cushing syndrome. All cases occurred among the 81 patients on PIs (event frequency among those on PIs: 11.1%; 95% confidence interval: 5.2% to 20.0%). Among patients on PIs, the major risk factor for hypothalamic-pituitary-adrenal axis dysfunction was having ≥2 injections within 6 months. CONCLUSIONS: In this retrospective cohort study, 11% of HIV-infected patients on PIs at the time of steroid injection were later diagnosed with hypothalamic-pituitary-adrenal axis dysfunction. Corticosteroid injections in HIV-infected patients on PIs should only be used with great caution and close monitoring.
