ABSTRACT

Background: Elevated levels of high-sensitivity cardiac troponin (hs-cTn) are suggestive of myocardial cell injury and coronary artery disease. We explored the association between hs-cTn and subclinical arteriosclerosis using coronary artery calcification (CAC) scoring among 337 virally suppressed patients with human immunodeficiency virus (HIV) who were ≥50 years old and without evidence of known coronary artery disease. Methods: Noncontrast cardiac computed tomography and blood sampling for hs-cTn, both subunit I (hs-cTnI) and subunit T (hs-cTnT), were performed. The relationship between CAC (Agatston score) and serum hs-cTn levels was analyzed using Spearman correlation and logistic regression models. Results: The patients, of whom 62% were male, had a median age of 54 years and had been on antiretroviral therapy for a median of 16 years; the CAC score was >0 in 50% of patients and ≥100 in 16%. Both hs-cTn concentrations were positively correlated with the Agatston score, with correlation coefficients of 0.28 and 0.27 (P < .001) for hs-cTnI and hs-cTnT, respectively. hs-cTnI and hs-cTnT concentrations of ≥4 and ≥5.3 pg/mL, respectively, provided the best performance for discriminating patients with Agatston scores ≥100, with a sensitivity and specificity of 76% and 60%, respectively, for hs-cTnI and 70% and 50% for hs-cTnT. In multivariable logistic regression analysis, each log unit increase in hs-cTnI level was independently associated with increased odds of having an Agatston score ≥100 (odds ratio, 2.83 [95% confidence interval, 1.69-4.75]; P <.001). Although not an independent predictor, hs-cTnT was also associated with an increased odds of having an Agatston score ≥100 (odds ratio, 1.58 [95% confidence interval, .92-2.73]; P = .10). Conclusions: Among Asians aged ≥50 years with well-controlled HIV infection and without established cardiovascular disease, 50% had subclinical arteriosclerosis. Increasing hs-cTnI and hs-cTnT concentrations were associated with an increased risk of severe subclinical arteriosclerosis, and hs-cTn may be a potential biomarker to detect severe subclinical arteriosclerosis.

ABSTRACT

BACKGROUND: We investigated the association between nonalcoholic fatty liver disease (NAFLD) plus or minus a concurrent diagnosis of nonalcoholic steatohepatitis (NASH) and incident diabetes mellitus (DM) and the risk factors associated with NAFLD or NASH development. METHODS: In this prospective study, we analyzed people with human immunodeficiency virus (HIV; PWH) aged ≥18 years without excessive alcohol consumption or hepatitis coinfections. NAFLD was defined as controlled attenuation parameter ≥248 dB/m, whereas NASH with significant disease activity and liver fibrosis was defined as a FibroScan-AST score ≥0.67. Cox proportional hazard regression was used to investigate the association between NAFLD with or without NASH and new-onset DM. RESULTS: Of 847 PWH, the median age at baseline was 45 years (interquartile range, 38-51; 43% female). Baseline NAFLD was associated with 2.8-fold higher risk of new-onset DM after adjusting for age, sex, family history of DM, antiretroviral therapy duration, smoking, statin use, stavudine/didanosine/zidovudine exposure, time-updated body mass index, hypertension, and dyslipidemia. Combined NAFLD and NASH at baseline had 3.1-fold higher new-onset DM risk. In separate analyses, baseline DM did not predict progression to NAFLD or NASH, but tenofovir alafenamide use was associated with an increased risk of NAFLD (hazard ratio [HR], 2.01; 95% confidence interval [CI], 1.02-4.02) or NASH development (2.31; 95% CI, 1.12-5.11). CONCLUSIONS: NAFLD alone or combined with NASH strongly predicts new-onset DM. This highlights the need for systematic risk assessments and management of NAFLD/NASH, as it may contribute to metabolic complications such as DM and subsequent cardiovascular diseases in PWH.

ABSTRACT

INTRODUCTION: A change in terminology from fatty liver disease to metabolic-associated fatty liver disease (MAFLD), along with modified diagnostic criteria, was proposed in 2020, and data regarding MAFLD burden in people living with HIV are limited. We investigated associations between MAFLD and immune activation, cardiovascular disease (CVD) risks including epicardial fat volume, and steatohepatitis in an Asian cohort. METHODS: We evaluated CVD risk (epicardial fat tissue, coronary artery calcium [CAC] score, and 10-year atherosclerotic CVD [ASCVD] score) in people living with HIV aged >50 years. Individuals with excessive alcohol consumption and viral hepatitis infections were excluded. MAFLD diagnosis was based on 2020 International Consensus criteria. Non-alcoholic steatohepatitis (NASH) with significant activity and liver fibrosis was defined as FibroScan-aspartate aminotransferase (FAST) score ≥0.67 and >0.35. Multivariate logistic regression models were used to investigate factors associated with MAFLD and NASH with significant activity and liver fibrosis. RESULTS: The median age was 54 years (interquartile range [IQR] 52-60) and current CD4 count was 613 (IQR 467-804) cells/mm3 . A total of 37% were female, and most (98%) people living with HIV were virally suppressed. The prevalence of MAFLD and non-alcoholic fatty liver disease was 35% and 38%, respectively. In multivariate analyses, higher body mass index, albumin, epicardial fat volume, and liver stiffness were significantly associated with MAFLD. A higher CD4/CD8 ratio was associated with a lower risk of MAFLD. People with HIV with MAFLD had higher odds of having NASH with significant activity and liver fibrosis (adjusted odds ratio 3.3; 95% confidence interval 1.6-6.6), and similar associations were also observed among different MAFLD categories. CONCLUSIONS: The complex relationship between MAFLD and immune activation, steatohepatitis, and epicardial fat tissue suggests an increased risk of advanced liver disease and CVDs beyond the traditional risk factors in people living with HIV with fatty liver disease.

ABSTRACT

There are limited data regarding bone health in older people living with HIV (PWH), especially those of Asian ethnicity. We aimed to determine whether BMD in well-suppressed HIV-infected men and women aged ≥ 50 years are different from HIV-uninfected controls. In a cross-sectional study, BMD by dual-energy X-ray absorptiometry and calciotropic hormones were measured. A total of 481 participants were consecutively enrolled (209 HIV+ men, 88 HIV- men, 126 HIV+ women and 58 HIV- women). PWH were on average 2.5 years younger [men: 55.0 vs. 57.5 yr; women: 54.0 vs. 58.0 yr] and had lower body mass index (BMI) [men: 23.2 vs. 25.1 kg/m2; women: 23.1 vs. 24.7 kg/m2] compared to the controls. The median duration since HIV diagnosis was 19 (IQR 15-21) years in men and 18 (IQR 15-21) years in women. Three-quarters of PWH had been treated with tenofovir disoproxil fumarate-containing antiretroviral therapy for a median time of 7.4 (IQR 4.5-8.9) years in men and 8.2 (IQR 6.1-10) years in women. In an unadjusted model, HIV+men had significantly lower BMD (g/cm2) at the total hip and femoral neck whereas there was a tend toward lower BMD in HIV+women. After adjusting for age, BMI, and other traditional osteoporotic risk factors, BMD of virologically suppressed older PWH did not differ from participants without HIV (P>0.1). PWH had lower serum 25(OH)D levels but this was not correlated with BMD. In conclusion, BMD in well-suppressed PWH is not different from non-HIV people, therefore, effective control of HIV infection and minimization of other traditional osteoporosis risk factors may help maintain good skeletal health and prevent premature bone loss in Asian PWH.

ABSTRACT

There is limited evidence about the long-term changes in nutritional status among the elderly people living with human immunodeficiency virus (PLWH). We aimed to investigate the changes in nutritional status and related factors over 4 years in the elderly PLWH. The longitudinal study was conducted prospectively among 250 PLWH, 50 years of age and older, receiving antiretroviral therapy (ART). The Mini Nutritional Assessment (MNA) and Thai Depression Scale (TDS) to assess nutritional status and depression, respectively, were performed at the outpatient clinic both at baseline and 4-year follow-up. Majority were male (60.8%) with median age of 58 years. The median CD4 was 612.5 cells/mm3 and 98% had HIV RNA <50 copies/mL. Median duration of ART was 20 years. Median body mass index was 23.1 kg/m2. The most common ART were rilpivirine (45.2%) and dolutegravir (18.8%). Fifty-one patients (20.4%) deteriorated in nutritional status and mean MNA scores declined (25.8 vs. 24.8, p < .001) at follow-up period. In multivariate analysis, high TDS scores (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.17-1.52), polypharmacy (OR, 1.35; 95% CI, 1.10-1.65), and high-density lipoprotein cholesterol (HDL-C) levels (OR, 1.04; 95% CI, 1.01-1.07) were associated factors of deterioration in nutritional status. In this 4-year longitudinal follow-up, 20% of the aging PLWH have deterioration of nutritional status. High TDS scores (depression), polypharmacy, and high HDL-C were significantly associated with declining nutritional status. Our findings highlight the importance of screening and monitoring nutritional and depression status in routine HIV treatment and care for geriatric HIV-infected population.
