Abstract
Human immunodeficiency virus (HIV) infection is associated with increased cardiovascular diseases (CVDs) even in patients with viral suppression by combination antiretroviral therapy (cART). Arterial stiffness is an independent predictor of CVDs in diseased individuals and the general population. Cardio-ankle vascular index (CAVI) is an index of arterial stiffness that has been shown to predict target organ damage. CAVI is less studied in HIV patients. We compared the levels of arterial stiffness using CAVI and associated factors among cART-treated and cART-naïve HIV patients to those of non-HIV controls. In a case-control design, 158 cART-treated HIV patients, 150 cART-naïve HIV patients and 156 non-HIV controls were recruited from a periurban hospital. We collected data on CVD risk factors, anthropometric characteristics, CAVI, and fasting blood samples to measure plasma glucose, lipid profile, and CD4+ cell counts. Metabolic abnormalities were defined using the JIS criteria. CAVI increased in cART-treated HIV patients compared to cART-naïve HIV patients and non-HIV controls (7.8 ± 1.4 vs 6.6 ± 1.1 vs 6.7 ± 1.4 respectively, p < 0.001). CAVI was associated with metabolic syndrome in non-HIV controls [OR (95% CI) = 2.14 (1.04-4.4), p = 0.039] and cART-naïve HIV patients [1.47 (1.21-2.38), p = 0.015], but not in cART-treated HIV patients [0.81 (0.52-1.26), p = 0.353]. In cART-treated HIV patients, a tenofovir (TDF)-based regimen (β = -0.46, p = 0.023) was associated with decreased CAVI and decreased CD4+ cell count (β = -0.23, p = 0.047) was associated with increased CAVI. In a periurban hospital in Ghana, compared to non-HIV controls or cART-naïve HIV patients, cART-treated HIV patients had increased arterial stiffness measured as CAVI. CAVI is associated with metabolic abnormalities in non-HIV controls and cART-naïve HIV patients, but not in cART-treated HIV patients. Patients on TDF-based regimens had decreased CAVI.

Dobe IS, Mocumbi AO, Majid N, Ayele B, Browne SH, Innes S. Earlier antiretroviral initiation is independently associated with better arterial stiffness in children living with perinatally acquired HIV with sustained viral suppression in Mozambique. South Afr J HIV Med 2021; 22:1282. [PMID: 34858652 PMCID: PMC8603154 DOI: 10.4102/sajhivmed.v22i1.1282] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 08/30/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Cardiovascular disease is a major driver of morbidity and mortality in adults living with HIV. The drivers of cardiovascular disease in children living with perinatally acquired HIV (PHIV) with sustained HIV viral suppression are unclear. OBJECTIVES We explored the contribution of HIV-specific risk factors to arterial stiffness independently of traditional risk factors (metabolic syndrome [MetS]) in prepubertal children with PHIV with sustained viral suppression in a low-income country in Africa. METHOD For this cross-sectional analysis, arterial stiffness was assessed by pulse wave velocity z-score (PWVz), measured using a Vicorder device. Metabolic syndrome components were measured. We retrospectively collected the antiretroviral therapy (ART) exposures, HIV stage, CD4 count and HIV viral load. A multivariate linear regression model was constructed for MetS components, retaining age and gender as obligatory variables. We then added HIV-related metrics to assess whether these had an independent or additive effect. RESULTS We studied 77 virally suppressed children with PHIV without evidence of cardiovascular disease (from medical history and physical examination). In the initial model, the PWVz was independently associated with each MetS component. The PWVz was higher in participants with proportionally greater visceral fat (waist/height ratio), elevated lipids (triglyceride/high-density lipoprotein ratio) and insulin resistance (log homeostatic model assessment [HOMA]). The addition of age at ART initiation increased the model R 2 value from 0.36 to 0.43. In the resulting model, younger age at ART initiation was independently associated with a better PWVz (P < 0.001). CONCLUSION Earlier ART initiation was independently associated with lower large artery stiffness. This effect was independent of the effect of elevated lipids, visceral fat and insulin resistance.

Comparison of Predicted Cardiovascular Risk Profiles by Different CVD Risk-Scoring Algorithms between HIV-1-Infected and Uninfected Adults: A Cross-Sectional Study in Tanzania. HIV AIDS (Auckl) 2021; 13:605-615. [PMID: 34113177 PMCID: PMC8184149 DOI: 10.2147/hiv.s304982] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 04/28/2021] [Indexed: 12/01/2022] Open
Abstract
Purpose Cardiovascular disease (CVD) risk assessment is a suitable way to differentiate between high-risk individuals requiring intervention and risk modification, and those at low risk. However, concerns have been raised when adopting a CVD-risk prediction algorithm for HIV-infected patients in sub-Saharan Africa. Patients and Methods We compared cardiovascular risk profiles between HIV-infected (with and without antiretroviral therapy (ART)) and HIV-uninfected adults as predicted by the American College of Cardiology/American Heart Association (ASCVD) and the Framingham cardiovascular risk score (FRS) algorithms and assessed the concordance of the algorithms in predicting 10-year CVD risk separately in HIV-infected and uninfected groups in a hospital-based cross-sectional study in Tanzania. A cross-sectional hospital-based study including 40 HIV-infected ART-naive, 64 HIV-infected on ART, and 50 HIV-uninfected adults was conducted. Traditional cardiovascular risk factors were determined by standard investigations. The primary outcome was the absolute 10-year CVD risk score based on the two algorithms. Results Compared to HIV-uninfected, HIV-infected adults were classified at a higher 10-year CVD risk. ASCVD algorithms predicted a higher proportion of high-risk individuals compared to FRS in both HIV-infected and uninfected groups. The concordance between ASCVD and FRS-lipid algorithms was reasonable for both HIV-infected and uninfected groups though relatively higher in the HIV-uninfected group. Conclusion HIV-infected individuals have a higher 10-year cardiovascular risk compared to HIV-uninfected persons. The concordance between ASCVD and FRS-lipid algorithms is reasonable in both HIV-uninfected and infected persons in Tanzania. Development of an HIV-specific algorithm is needed to accurately predict CVD risk in this population at high-risk.

A comparative analysis of blood pressure in HIV-infected patients versus uninfected controls residing in Sub-Saharan Africa: a narrative review. J Hum Hypertens 2020; 34:692-708. [PMID: 32709885 DOI: 10.1038/s41371-020-0385-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 07/02/2020] [Accepted: 07/16/2020] [Indexed: 12/11/2022]
Abstract
Elevated blood pressure (BP) is an important risk factor for cardiovascular disease and mortality in Sub-Saharan Africa (SSA). We reviewed the literature comparing BP in treated HIV-infected populations against untreated and/or uninfected controls from SSA. We conducted a narrative review through PubMed and EBSCO Discovery Service to determine estimates of raised BP and hypertension in HIV-infected patients versus untreated/uninfected controls (1 January 2005 to 31 July 2019 and 9 May 2020). We included 19 eligible studies that compared treated HIV-infected with untreated and/or uninfected controls. In studies comparing treated HIV-infected patients to uninfected controls, studies including 6882 (56.30%) and 21,819 (79.2%) participants reported lower BP and hypertension prevalence, respectively in HIV-infected patients; whereas studies including 753 (6.16%) and 3553 (12.9%) participants showed a higher BP and hypertension prevalence. Lastly, 4588 (37.54%) and 2180 (7.91%) participants showed no difference in BP and the prevalence of hypertension. When comparing BP of treated versus untreated HIV-infected patients, studies including 5757 (44.2%) patients reported lower BP in treated patients; while studies with 200 (1.53%) patients showed higher BP and 7073 (54.28%) showed no difference in BP. For hypertension status, studies with 4547 (74.5%) patients reported a lower prevalence of hypertension in treated patients; whereas studies with 598 (9.80%) patients showed higher prevalence; and 959 (15.7%) no difference in prevalence between treated versus untreated HIV-infected patients. In studies conducted in Sub-Saharan Africa, the majority of the findings indicate lower blood pressure and/or prevalence of hypertension in treated HIV-infected individuals compared to untreated and uninfected controls.

Association of HIV-infection, antiretroviral treatment and metabolic syndrome with large artery stiffness: a cross-sectional study. BMC Infect Dis 2018; 18:708. [PMID: 30594160 PMCID: PMC6311066 DOI: 10.1186/s12879-018-3637-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2017] [Accepted: 12/19/2018] [Indexed: 11/10/2022] Open
Abstract
Background Effective combined antiretroviral therapy (cART) has improved life expectancy among people living with HIV-1 infection. Treated HIV-1infection increases the prevalence of metabolic syndrome (MS). Despite sub-Saharan Africa having among the highest rates of HIV-1 infection, the effects of MS in HIV-1-infected individuals on cardiovascular risk is poorly explored. The aim of the study was to assess whether MS and/or HIV-1 treatment correlates with large elastic artery stiffness in HIV-1-infected patients treated with first-line cART. Methods The study sample comprised of 102 subjects free of cardiovascular disease and major risk factors divided into two groups based on HIV-1 infection, treatment, and MS status: HIV-1+/cART+/MS+ (n = 12); HIV-1+/cART−/MS+ (n = 16); HIV-1−/ MS+ (n = 10); HIV-1+/cART+/MS− (n = 42); HIV-1+/cART−/MS− (n = 32); HIV-1−/ MS− (n = 39). MS was established according the International Diabetes Federation definition. Large artery stiffness was measured using applanation tonometry to assess aortic pulse wave velocity (aPWV) and aortic augmentation index at heart rate of 75 bpm (AIx@HR75). cART included lamivudine/zidovudine and nevirapine or efavirenz. Results The prevalence of MS in the HIV-1-infected patients was 28%. There were no significant differences in aPWV in the non-MS groups. However, in subjects with MS, aPWV was significantly higher in the HIV-1 cART patients (9.0 ± 1.9 m/s) compared with both controls (7.5 ± 1.8 m/s; P = 0.018) and untreated HIV-1 patients (7.7 ± 1.3 m/s; P = 0.023), and these differences remained after adjustment for blood pressure and sex. Aortic PWV was significantly elevated (P = 0.009) in HIV-1 cART patients with MS compared to their counterparts without MS. Untreated HIV-1 patients with MS also demonstrated increased aPWV compared to their counterparts without MS (P = 0.05). Aortic AIx@HR75 was, on average, ~ 5% higher in HIV-1 cART patients with MS (28.3 ± 62% compared with untreated HIV-1 patients with MS (23.5 ± 9%; P = 0.075). Sub-group multivariate analysis identified MS as an independent predictor of increased aPWV in HIV-1 cART patients. Conclusions Our study established that presence of MS in HIV-1 patients on treatment was associated with increased aPWV and hence increased arterial stiffness in sub-Saharan African HIV-1 patients on first-line cART.
