HIV infection and glycemic response to newly initiated diabetic medical therapy
ABSTRACT OBJECTIVES:: Type 2 diabetes (DM2) is increasingly common in HIV-infected individuals. Antiretroviral agents and chronic inflammation may adversely affect glycemic control. However, little is known about the effectiveness of diabetic medical therapy in HIV-infected patients. The objective of this study was to compare the effectiveness of initial diabetic medical therapy in patients with and without HIV infection. DESIGN:: A retrospective cohort study was conducted among adults with DM2 initiating diabetic medications within the Centers for AIDS Research Network of Integrated Clinical Systems cohort. METHODS:: Generalized estimating equations were used to compare changes in hemoglobin A1c (HbA1c) through the year after initiation of therapy, controlling for baseline HbA1c and demographic and clinical covariates. RESULTS:: Two hundred and eighty-six HIV-infected patients and 858 age and sex-matched HIV-uninfected patients initiated diabetic medications during the study period. Overall, patients had an adjusted absolute mean reduction in HbA1c of 1.04% [95% confidence interval (CI) -0.87 to -1.22] during the first year of therapy. HIV-infected patients achieved significantly smaller reductions in HbA1c, with an absolute mean difference of -0.17% (95% CI -0.28 to -0.06; P = 0.003). On subanalyses, HIV-infected patients on a protease inhibitor-based regimen had significantly smaller reductions in HbA1c compared to HIV-uninfected patients (adjusted absolute difference -0.21%, 95% CI -0.35 to -0.08; P = 0.002). CONCLUSION:: Patients with HIV infection who initiate diabetic medical therapy achieve smaller reductions in HbA1c than patients without HIV infection in the course of routine clinical care. This less robust response may in part be related to use of antiretrovirals that exacerbate insulin resistance, specifically protease inhibitors.

ABSTRACT: With the advances in antiretroviral therapy (ART), HIV infection has been transformed into a chronic medical condition that can be effectively managed like diabetes or hypertension. For HIV care providers, the focus of care for many patients has shifted from prevention of opportunistic infection and AIDS-related conditions to age-related cardiometabolic comorbidities, including cardiovascular disease, diabetes, obesity, and frailty. Numerous reports have highlighted that these diseases are occurring at an earlier age among HIV-infected persons. However, there is an ongoing debate regarding the role of HIV infection, ART, and other factors that may underlie the accelerated occurrence of these diseases. Herein, we review the epidemiology of the US HIV epidemic with regards to several metabolic comorbidities and address mechanisms that likely contribute to the current nature of HIV disease.Current HIV/AIDS Reports 01/2014; 11(1).
