HIV infection and glycemic response to newly initiated diabetic medical therapy.

ABSTRACT: 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.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.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.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).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.

Project description:BackgroundThough many trials had examined the effectiveness of taking insulin with or without oral agents, there are limited real-world data, particularly among patients with type 2 diabetes mellitus (T2DM) in the resource limited settings. This study aimed to examine level of glycemic control among patients with T2DM after initiation of insulin and factors associated with poor glycemic control.MethodsAn analysis of retrospective medical records of patients with T2DM who initiated insulin due to uncontrolled hyperglycemia by oral agents was conducted from 2015-2020 in the University of Gondar Comprehensive Specialized Hospital. Difference in median fasting plasma glucose (FPG) before and after insulin initiations was examined by a Wilcoxon signed-rank test. Kruskal Wallis test was performed to explore difference in the median level of FPG among treatment groups. A logistic regression model was also used to identify associated factors of poor glycemic control after insulin initiation. Statistical significance was declared at p < 0.05.ResultsOf 424 enrolled patients with T2DM, 54.7% were males and the mean age was 59.3±9.3 years. A Wilcoxon signed-rank test showed that there was significant deference in FPG before and after insulin initiation (P < 0.001). A declining trend of blood glucose was observed during the 1-year follow-up period of post-initiation. However, majority of the participants did not achieve target glucose levels. Participants who had higher FPG and systolic blood pressure (SBP) before insulin initiation were found more likely to have poor glycemic control after insulin initiation. Similarly, patients who received atorvastatin compared with simvastatin were found to have poor glycemic control in the post-period of initiation (P = 0.04). Premixed insulin was associated with a lower likelihood of poor glycemic control than neutral protamine Hagedorn (NPH) insulin (P < 0.001).ConclusionFollowing insulin initiation, a significant change in glycemic level and declining trend of FPG was observed during a 1-year follow-up period. However, the majority of patients still had a poorly controlled glycemic level. Appropriate management focusing on predictors of glycemic control would be of a great benefit to achieve glycemic control.

Project description:IntroductionOne consequence of population aging is an increase in the number of elderly patients with diabetes mellitus. These elderly patients often experience atherosclerotic complications, and diabetes prevention and management are strongly desired to promote health and reduce the financial burden on the healthcare system. In this study, we conducted an age-specific evaluation of the effectiveness and safety of comprehensive management with newly initiated insulin therapy over a 1-year period in elderly (≥65 years) compared with non-elderly (≤64 years) Japanese patients with uncontrolled diabetes [glycated hemoglobin (HbA1c) ≥ 8% for ≥ 3 months].MethodsThis retrospective single-center cohort study was conducted in Japan. We screened all outpatients with diabetes mellitus who visited the clinic for diabetes treatment between December 2006 and March 2011. Of these patients, 132 with type 2 diabetes who were newly initiated on insulin therapy for continued poor glycemic control and undergoing comprehensive management through self-monitoring of blood glucose (SMBG) were registered to the study.ResultsThirty-two of 132 registered patients were excluded from the analysis. Among the 100 patients (67 non-elderly, 33 elderly) included in the analysis, median age and proportion of male patients was 69 years and 66.7%, respectively, among the elderly, and 52 years and 68.7%, respectively, among the non-elderly patients. After initiation of insulin therapy, median HbA1c levels improved from 9.6% to 7.2% in elderly patients, and from 10.8% to 7.3% in non-elderly patients at baseline and 12 months. Severe hypoglycemic events were not observed in either patient group; however, uncontrolled diabetes was ongoing in 31.8% of non-elderly and 15.4% of elderly patients, and obesity was associated with poor glycemic control.ConclusionOur results indicate that the effectiveness and safety of newly initiated insulin therapy are similar between elderly and non-elderly Japanese patients with uncontrolled diabetes, and highlight the importance of comprehensive management using SMBG to avoid hypoglycemia. Better glycemic control supported by adequate intensive management is required to improve mortality and morbidity.
