IntroductionComorbidities including diabetes mellitus (DM) among people living with HIV (PLHIV) are of increasing clinical concerns in combination antiretroviral therapy (cART) era. We aimed to determine the incidence and risk factors of new‐onset DM among PLHIV in Asian settings.Methods PLHIV from a regional observational cohort without DM prior to antiretroviral therapy (ART) initiation were included in the analysis. DM was defined as having a fasting blood glucose ≥126 mg/dL, glycated haemoglobin ≥6.5%, a two‐hour plasma glucose ≥200 mg/dL, or a random plasma glucose ≥200 mg/dL. A Cox regression model, stratified by site, was used to identify risk factors associated with DM.Results and discussionOf the 1927 participants included, 127 were diagnosed with DM after ART initiation. Median follow‐up time from ART initiation to DM diagnosis was 5.9 years (interquartile range (IQR): 2.8 to 8.9 years). The crude incidence rate of DM was 1.08 per 100 person‐years (100 PYS), 95% confidence interval (CI) (0.9 to 1.3). In the multivariate analysis, later years of follow‐up (2011 to 2013: HR = 2.34, 95% CI 1.14 to 4.79, p = 0.02; and 2014 to 2017: HR = 7.20, 95% CI 3.27 to 15.87, p < 0.001) compared to <2010, older age (41 to 50 years: HR = 2.46, 95% CI 1.39 to 4.36, p  = 0.002; and >50 years: HR = 4.19, 95% CI 2.12 to 8.28, p < 0.001) compared to <30 years, body mass index (BMI) >30 kg/m2 (HR = 4.3, 95% CI 1.53 to 12.09, p = 0.006) compared to BMI <18.5 kg/m2, and high blood pressure (HR = 2.05, 95% CI 1.16 to 3.63, p = 0.013) compared to those without high blood pressure, were associated with developing DM. The hazard was reduced for females (HR = 0.47, 95% CI 0.28 to 0.80, p = 0.006).ConclusionsType 2 DM in HIV‐infected Asians was associated with later years of follow‐up, high blood pressure, obesity and older age. This highlights the importance of monitoring and routine screening for non‐communicable diseases including DM as PLHIV age.

Objectives With aging of the HIV‐positive population, cardiovascular disease (CVD) increasingly contributes to morbidity and mortality. We investigated CVD‐related and other causes of death (CODs) and factors associated with CVD in a multi‐country Asian HIV‐positive cohort. Methods Patient data from 2003–2017 were obtained from the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD). We included patients on antiretroviral therapy (ART) with > 1 day of follow‐up. Cumulative incidences were plotted for CVD‐related, AIDS‐related, non‐AIDS‐related, and unknown CODs, and any CVD (i.e. fatal and nonfatal). Competing risk regression was used to assess risk factors of any CVD. Results Of 8069 patients with a median follow‐up of 7.3 years [interquartile range (IQR) 4.4–10.7 years], 378 patients died [incidence rate (IR) 6.2 per 1000 person‐years (PY)], and this total included 22 CVD‐related deaths (IR 0.36 per 1000 PY). Factors significantly associated with any CVD event (IR 2.2 per 1000 PY) were older age [sub‐hazard ratio (sHR) 2.21; 95% confidence interval (CI) 1.36–3.58 for age 41–50 years; sHR 5.52; 95% CI 3.43–8.91 for ≥ 51 years, compared with < 40 years], high blood pressure (sHR 1.62; 95% CI 1.04–2.52), high total cholesterol (sHR 1.89; 95% CI 1.27–2.82), high triglycerides (sHR 1.55; 95% CI 1.02–2.37) and high body mass index (BMI) (sHR 1.66; 95% CI 1.12–2.46). CVD crude IRs were lower in the later ART initiation period and in lower middle‐ and upper middle‐income countries. Conclusions The development of fatal and nonfatal CVD events in our cohort was associated with older age, and treatable risk factors such as high blood pressure, triglycerides, total cholesterol and BMI. Lower CVD event rates in middle‐income countries may indicate under‐diagnosis of CVD in Asian‐Pacific resource‐limited settings.

Rates of discontinuation of first- and second-line regimens have decreased over the last decade in Asia. Subsequent regimens were of shorter duration compared to the first-line regimen initiated in the same year period. Lower CD4 T-cell count and the use of suboptimal regimens were important factors associated with higher risk of treatment switch.

Objectives To assess second‐line antiretroviral therapy (ART) virological failure and HIV drug resistance‐associated mutations (RAMs), in support of third‐line regimen planning in Asia. Methods Adults > 18 years of age on second‐line ART for ≥ 6 months were eligible. Cross‐sectional data on HIV viral load (VL) and genotypic resistance testing were collected or testing was conducted between July 2015 and May 2017 at 12 Asia‐Pacific sites. Virological failure (VF) was defined as VL > 1000 copies/mL with a second VL > 1000 copies/mL within 3–6 months. FASTA files were submitted to Stanford University HIV Drug Resistance Database and RAMs were compared against the IAS‐USA 2019 mutations list. VF risk factors were analysed using logistic regression. Results Of 1378 patients, 74% were male and 70% acquired HIV through heterosexual exposure. At second‐line switch, median [interquartile range (IQR)] age was 37 (32–42) years and median (IQR) CD4 count was 103 (43.5–229.5) cells/µL; 93% received regimens with boosted protease inhibitors (PIs). Median duration on second line was 3 years. Among 101 patients (7%) with VF, CD4 count > 200 cells/µL at switch [odds ratio (OR) = 0.36, 95% confidence interval (CI): 0.17–0.77 vs. CD4 ≤ 50) and HIV exposure through male–male sex (OR = 0.32, 95% CI: 0.17–0.64 vs. heterosexual) or injecting drug use (OR = 0.24, 95% CI: 0.12–0.49) were associated with reduced VF. Of 41 (41%) patients with resistance data, 80% had at least one RAM to nonnucleoside reverse transcriptase inhibitors (NNRTIs), 63% to NRTIs, and 35% to PIs. Of those with PI RAMs, 71% had two or more. Conclusions There were low proportions with VF and significant RAMs in our cohort, reflecting the durability of current second‐line regimens.
