Predictors of glycaemic control among HIV-positive veterans with diabetes.
Antiretroviral therapy has decreased HIV-related mortality. However, the incidence of diabetes as a co-morbidity is increasing as HIV-positive patients age. The purpose of this study was to assess the correlation between markers of HIV-infection and diabetes and to determine the proportion of patients achieving an haemoglobin A1c (HbA1c) goal <7% according to specific antiretroviral therapy regimens and adherence. In this retrospective study, HIV-positive veterans with diabetes from 2007 to 2012 were identified. Patients were required to be on the same antiretroviral therapy and diabetes regimen for ≥3 months. In 56 patients, it was identified that for each unit increase in log10 viral load, HbA1c increased 0.67 units (p = 0.0085). Only 38% of patients prescribed a protease inhibitor-based regimen vs. 56% of patients not on a protease inhibitor-based regimen achieved an HbA1c goal (p = 0.1864). Additionally, patients on an insulin-based regimen and patients that were less adherent were less likely to be at HbA1c goal (p = 0.018 and p = 0.0378, respectively). Patients with higher viral loads and patients that were less adherent to antiretroviral therapy were more likely to have a higher HbA1c demonstrating that poor adherence to antiretroviral therapy leads to poor control of both disease states.
