Abstract
INTRODUCTION Immune dysregulation persists in people with HIV (PWH) on antiretroviral therapy (ART) and may lead to accelerated vascular ageing and cardiovascular disease (CVD). While delayed time to initiation of ART has been linked to worse cardiovascular outcomes, the effect of ART initiation during acute infection on these outcomes is not well understood. METHODS Participants were enrolled from the SEARCH010/RV254 acute HIV (AHI) and HIV-NAT chronic HIV (CHI) cohorts in Thailand. Participants with 6-year follow-up and viral suppression (viral load < 50 copies/μL) at follow-up were included. Both unmatched cohorts and age and gender-matched cohorts were analysed. Demographics, HIV laboratories, and cardiovascular risk factors from enrolment and 6-year follow-up were obtained from electronic records. Framingham Risk Score (FRS), vascular age (VA), vascular age deviation (VAD), and 10-year atherosclerotic cardiovascular disease (ASCVD) risk were calculated from previously published equations. Vascular outcomes in AHI and CHI cohorts were compared, and univariable and multivariable linear regression analyses were used to investigate risk factors associated with worse vascular scores. RESULTS In all, 373 AHI participants and 608 CHI participants were identified. AHI participants were of younger age, had a higher prevalence of syphilis and a lower prevalence of prior hepatitis B, tuberculosis, diabetes, and hypertension. Higher CD4 T-cell and lower CD8 T-cell counts were seen in the AHI cohort at enrolment and 6-year follow-up. In all participants, the AHI cohort had a lower median FRS (p < 0.001) and VA (p < 0.001), but higher VAD (p < 0.001). However, in matched cohorts, no differences were found in FRS-based outcomes. In all participants, higher VAD after 6 years of ART was associated with higher body mass index (p < 0.001) and higher CD4 count (p < 0.001), which persisted in multivariable analysis. When FRS components were analysed individually, CD4 count was associated only with male sex and cholesterol. CONCLUSIONS We did not identify differences in FRS-based vascular outcomes at 6 years in matched cohorts of participants who started ART during AHI versus CHI. We identified a correlation between higher CD4 count and worse FRS-based vascular outcomes, which may be driven by underlying metabolic risk factors. Further study is needed to confirm these findings and evaluate underlying mechanisms.

Abstract
HIV type 1 (HIV-1) is the causative agent of AIDS. Since the start of the epidemic, HIV/AIDS has been responsible for ≈40 million deaths. Additionally, an estimated 39 million people are currently infected with the virus. HIV-1 primarily infects immune cells, such as CD4+ (cluster of differentiation 4+) T lymphocytes (T cells), and as a consequence, the number of CD4+ T cells progressively declines in people living with HIV. Within a span of ≈10 years, HIV-1 infection leads to the systemic failure of the immune system and progression to AIDS. Fortunately, potent antiviral therapy effectively controls HIV-1 infection and prevents AIDS-related deaths. The efficacy of the current antiviral therapy regimens has transformed the outcome of HIV/AIDS from a death sentence to a chronic disease with a prolonged lifespan of people living with HIV. However, antiviral therapy is not curative, is challenged by virus resistance, can be toxic, and, most importantly, requires lifelong adherence. Furthermore, the improved lifespan has resulted in an increased incidence of non-AIDS-related morbidities in people living with HIV including cardiovascular diseases, renal disease, liver disease, bone disease, cancer, and neurological conditions. In this review, we summarize the current state of knowledge of the cardiovascular comorbidities associated with HIV-1 infection, with a particular focus on hypertension. We also discuss the potential mechanisms known to drive HIV-1-associated hypertension and the knowledge gaps in our understanding of this comorbid condition. Finally, we suggest several directions of future research to better understand the factors, pathways, and mechanisms underlying HIV-1-associated hypertension in the post-antiviral therapy era.

Incidence of Hypertension and Blood Pressure Changes in Persons With Human Immunodeficiency Virus at High Risk for Cardiovascular Disease Switching From Boosted Protease Inhibitors to Dolutegravir: A Post-hoc Analysis of the 96-week Randomised NEAT-022 Trial. Clin Infect Dis 2023; 77:991-1009. [PMID: 37207617 DOI: 10.1093/cid/ciad297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 04/11/2023] [Accepted: 05/15/2023] [Indexed: 05/21/2023] Open
Abstract
BACKGROUND Integrase inhibitors have been recently linked to a higher risk for hypertension. In NEAT022 randomized trial, virologically suppressed persons with human immunodeficiency virus (HIV, PWH) with high cardiovascular risk switched from protease inhibitors to dolutegravir either immediately (DTG-I) or after 48 weeks (DTG-D). METHODS Primary endpoint was incident hypertension at 48 weeks. Secondary endpoints were changes in systolic (SBP) and diastolic (DBP) blood pressure; adverse events and discontinuations associated with high blood pressure; and factors associated with incident hypertension. RESULTS At baseline, 191 (46.4%) participants had hypertension and 24 persons without hypertension were receiving antihypertensive medications for other reasons. In the 197 PWH (n = 98, DTG-I arm; n = 99, DTG-D arm) without hypertension or antihypertensive agents at baseline, incidence rates per 100 person-years were 40.3 and 36.3 (DTG-I) and 34.7 and 52.0 (DTG-D) at 48 (P = .5755) and 96 (P = .2347) weeks. SBP or DBP changes did not differed between arms. DBP (mean, 95% confidence interval) significantly increased in both DTG-I (+2.78 mmHg [1.07-4.50], P = .0016) and DTG-D (+2.29 mmHg [0.35-4.23], P = .0211) arms in the first 48 weeks of exposure to dolutegravir. Four (3 under dolutegravir, 1 under protease inhibitors) participants discontinued study drugs due to adverse events associated with high blood pressure. Classical factors, but not treatment arm, were independently associated with incident hypertension. CONCLUSIONS PWH at high risk for cardiovascular disease showed high rates of hypertension at baseline and after 96 weeks. Switching to dolutegravir did not negatively impact on the incidence of hypertension or blood pressure changes relative to continuing protease inhibitors.

Cardiovascular events in delayed presentation of HIV: the prospective PISCIS cohort study. Front Med (Lausanne) 2023; 10:1182359.

Abstract
Objectives People with HIV (PWH) have a higher cardiovascular risk than the general population. It remains unclear, however, whether the risk of cardiovascular disease (CVD) is higher in late HIV presenters (LP; CD4 ≤ 350 cells/μL at HIV diagnosis) compared to PWH diagnosed early. We aimed to assess the rates of incident cardiovascular events (CVEs) following ART initiation among LP compared to non-LP. Methods From the prospective, multicentre PISCIS cohort, we included all adult people with HIV (PWH) initiating antiretroviral therapy (ART) between 2005 and 2019 without prior CVE. Additional data were extracted from public health registries. The primary outcome was the incidence of first CVE (ischemic heart disease, congestive heart failure, cerebrovascular, or peripheral vascular disease). The secondary outcome was all-cause mortality after the first CVE. We used Poisson regression. Results We included 3,317 PWH [26 589.1 person/years (PY)]: 1761 LP and 1556 non-LP. Overall, 163 (4.9%) experienced a CVE [IR 6.1/1000PY (95%CI: 5.3-7.1)]: 105 (6.0%) LP vs. 58 (3.7%) non-LP. No differences were observed in the multivariate analysis adjusting for age, transmission mode, comorbidities, and calendar time, regardless of CD4 at ART initiation [aIRR 0.92 (0.62-1.36) and 0.84 (0.56-1.26) in LP with CD4 count <200 and 200- ≤ 350 cells/μL, respectively, compared to non-LP]. Overall mortality was 8.5% in LP versus 2.3% in non-LP (p < 0.001). Mortality after the CVE was 31/163 (19.0%), with no differences between groups [aMRR 1.24 (0.45-3.44)]. Women vs. MSM and individuals with chronic lung and liver disease experienced particularly high mortality after the CVE [aMRR 5.89 (1.35-25.60), 5.06 (1.61-15.91), and 3.49 (1.08-11.26), respectively]. Sensitivity analyses including only PWH surviving the first 2 years yielded similar results. Conclusion CVD remains a common cause of morbidity and mortality among PWH. LP without prior CVD did not exhibit an increased long-term risk of CVE compared with non-LP. Identifying traditional cardiovascular risk factors is essential for CVD risk reduction in this population.

Abstract
BACKGROUND High blood pressure (HBP), including hypertension (HTN), is a predictor of cardiovascular events, and is an emerging challenge in young persons. The risk of cardiovascular events may be further amplified among people living with HIV (PLHIV). We determined the prevalence of HBP and associated factors among PLHIV aged 13 to 25 years in Rwenzori region, western Uganda. METHODS We conducted a cross-sectional study among PLHIV aged 13 to 25 years at nine health facilities in Kabarole and Kasese districts during September 16 to October 15, 2021. We reviewed medical records to obtain clinical and demographic data. At a single clinic visit, we measured and classified BP as normal (< 120/ < 80 mmHg), elevated (120/ < 80 to 129/ < 80), stage 1 HTN (130/80 to 139/89), and stage 2 HTN (≥ 140/90). We categorized participants as having HBP if they had elevated BP or HTN. We performed multivariable analysis using modified Poisson regression to identify factors associated with HBP. RESULTS Of the 1,045 PLHIV, most (68%) were female and the mean age was 20 (3.8) years. The prevalence of HBP was 49% (n = 515; 95% confidence interval [CI], 46%-52%), the prevalence of elevated BP was 22% (n = 229; 95% CI, 26%-31%), and the prevalence of HTN was 27% (n = 286; 95% CI, 25%-30%), including 220 (21%) with stage 1 HTN and 66 (6%) with stage 2 HTN. Older age (adjusted prevalence ratio [aPR], 1.21; 95% CI, 1.01-1.44 for age group of 18-25 years vs. 13-17 years), history of tobacco smoking (aPR, 1.41; 95% CI, 1.08-1.83), and higher resting heart rate (aPR, 1.15; 95% CI, 1.01-1.32 for > 76 beats/min vs. ≤ 76 beats/min) were associated with HBP. CONCLUSIONS Nearly half of the PLHIV evaluated had HBP, and one-quarter had HTN. These findings highlight a previously unknown high burden of HBP in this setting's young populations. HBP was associated with older age, elevated resting heart rate, and ever smoking; all of which are known traditional risk factors for HBP in HIV-negative persons. To prevent future cardiovascular disease epidemics among PLHIV, there is a need to integrate HBP/HIV management.

Abstract
Exposure to anti-retroviral therapy in HIV infection has been associated with hypertension, but whether and to what extent HIV-related factors and anti-retroviral treatment contribute to hypertension is not well defined; in addition, data are particularly scarce in Sub-Saharan Africa. Aim of the study was to investigate prevalence and awareness of hypertension in a cohort of people living with HIV (PLWHIV) on anti-retroviral therapy in rural Tanzania, and to identify possible predictors of hypertension. A cross-sectional study on hypertension in PLWHIV was conducted at Tosamaganga District Hospital, Iringa Region, Tanzania. Subjects on anti-retroviral therapy, age 26-80 years and with monthly attendance to the HIV clinic, were considered eligible. A total number of 242 patients were included in the analysis. Sixty-two subjects (26%) had hypertension, the majority (77%) of them not aware of the condition and/or not on treatment. Older age, higher BMI and lower baseline T-CD4 count were predictors of hypertension at multivariate analysis. The results of the study suggest that hypertension screening should become part of ordinary care of PLWHIV in Tanzania, particularly in subjects with more severe immunosuppression. Leveraging already existing HIV services could be an option to prevent the burden of non-AIDS complication and related deaths.

Abstract
BACKGROUND HIV induces several metabolic derangements that contribute to cardiovascular disease, but it is unclear if HIV increases diabetes or hypertension risk. Refining longitudinal relationships between HIV-specific factors and cardiovascular disease risk factors across different care settings may help inform cardiovascular disease prevention among people with HIV (PWH). METHODS We tested the hypothesis that long-term higher cumulative viral load (viremia-copy-year) is associated with higher risk of diabetes and hypertension by analyzing electronic records of PWH from 2 distinct health systems in Chicago (Northwestern Medicine and Howard Brown Health Care) receiving care in 2004 to 2019. We used joint longitudinal-survival models to assess multivariable-adjusted associations. Subgroup analyses per site were also conducted. RESULTS We observed 230 (3.0%) incident diabetes cases in 7628 PWH without baseline diabetes and 496 (6.7%) hypertension cases in 7450 PWH without baseline hypertension. Pooled analysis showed a direct association of viremia-copy-year with incident hypertension (hazards ratio, 1.20 [95% CI, 1.14-1.26]) but not with diabetes (hazards ratio, 1.03 [95% CI, 0.96-1.10]). However, site-specific differences existed whereby the Northwestern-only analysis demonstrated a significant association of viremia-copy-year with hypertension (hazards ratio, 1.29 [95% CI, 1.08-1.32]). Additionally, higher social deprivation index (both sites) and diagnosis of mental health disorder (Howard Brown Health only) was associated with higher diabetes and hypertension risk. CONCLUSIONS Cumulative viral load may be associated with incident hypertension among PWH. Associations of HIV control with cardiovascular disease risk factors among PWH may differ by health care system context.

Risk Factors for Incident Hypertension Within 1 Year of Initiating Antiretroviral Therapy Among People with HIV. AIDS Res Hum Retroviruses 2022; 38:735-742.

Abstract
Hypertension (HTN) is a common comorbidity among people with HIV and associated with an increased risk for atherosclerotic cardiovascular disease and chronic kidney disease. The relationship of antiretroviral therapy (ART) initiation to incident HTN remains a clinical question. We determined HTN incidence at 48 weeks of follow-up among ART-naive participants without HTN and not taking antihypertensive medications at ART initiation through randomized clinical trials through the AIDS Clinical Trial Group between 1999 and 2011. We assessed the association of baseline characteristics, including randomized ART agents with HTN incidence at 48 weeks using Poisson regression models. Incident HTN was defined as blood pressure ≥130/80 mmHg, or use of antihypertensive medication. Among 2,614 participants, mean age was 37 ± 10 years, 79% male sex, and 36% African American race. After 48 weeks, 839 participants (32%) developed HTN. Receiving a non-nucleoside reverse transcriptase inhibitor (NNRTI) was associated with an increased relative risk (RR) of incident HTN, while the risk was lower for protease inhibitor use. Stavudine and efavirenz were associated with an increased RR of developing HTN, while tenofovir disoproxil fumarate, darunavir/ritonavir, and atazanavir/ritonavir were associated with a decreased risk of developing HTN. Additionally, older age, higher body mass index (BMI), and having hepatitis C were associated with an increased risk for developing HTN, while women and participants with a higher baseline CD4 count were at a decreased risk of developing HTN at 48 weeks. One third of these ART naive participants developed HTN after ART initiation. NNRTIs, notably efavirenz, and stavudine were associated with an increased risk of HTN. Additional factors associated with HTN included traditional factors like older age and higher BMI, and advanced HIV disease (lower CD4 count). (Clinicaltrials.gov: NCT00001137).

Anthropometry, body composition, early growth and chronic disease risk factors among Zambian adolescents exposed or not to perinatal maternal HIV. Br J Nutr 2022; 129:1-12. [PMID: 35695182 PMCID: PMC9899567 DOI: 10.1017/s0007114522001775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 04/13/2022] [Accepted: 05/30/2022] [Indexed: 11/07/2022]
Abstract
Early life exposures and growth patterns may affect long-term risk of chronic non-communicable diseases (NCD). We followed up in adolescence two Zambian cohorts (n 322) recruited in infancy to investigate how two early exposures - maternal HIV exposure without HIV infection (HEU) and early growth profile - were associated with later anthropometry, body composition, blood lipids, Hb and HbA1c, blood pressure and grip strength. Although in analyses controlled for age and sex, HEU children were thinner, but not shorter, than HIV-unexposed, uninfected (HUU) children, with further control for socio-demographic factors, these differences were not significant. HEU children had higher HDL-cholesterol than HUU children and marginally lower HbA1c but no other biochemical or clinical differences. We identified three early growth profiles - adequate growth, declining and malnourished - which tracked into adolescence when differences in anthropometry and body fat were still seen. In adolescence, the early malnourished group, compared with the adequate group, had lower blood TAG and higher HDL, lower grip strength (difference: -1·87 kg, 95 % CI -3·47, -0·27; P = 0·02) and higher HbA1c (difference: 0·5 %, 95 % CI 0·2, 0·9; P = 0·005). Lower grip strength and higher HbA1c suggest the early malnourished children could be at increased risk of NCD in later life. Including early growth profile in analyses of HIV exposure reduced the associations between HIV and outcomes. The results suggest that perinatal HIV exposure may have no long-term effects unless accompanied by poor early growth. Reducing the risk of young child malnutrition may lessen children's risk of later NCD.

Abstract
BACKGROUND While the fast extension of combination antiretroviral therapy (cART) has resulted in significant increases in life expectancy, disorders such as cardiometabolic syndrome (CMetS), which have received less attention, are becoming a major concern in HIV/AIDS patients (PLWHA). OBJECTIVES The purpose of this research was to identify biomarkers and determine the prevalence of CMetS in PLWHA using the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) tools. METHODS Between January 2019 and February 2021, a hospital-based study of HIV-infected patients (n = 288) was conducted. The data were analyzed using binary logistic regression. To control the effect of confounders, independent variables with a P-value of <.20 in the bivariate logistic regression were incorporated into multivariate logistic regression. Statistical significance was defined as a 95% confidence interval and a P-value of less than .05. RESULTS The risk of CMetS increased twofold as age increased each year (P = .009), 1.2 times as the age at which cART began increased (P = .015), and 6 times with 1 or more co-morbidities (P = .028), according to the NCEP tool. Furthermore, significant NCEP-CMetS correlations were produced by a rise in diastolic blood pressure (P < .001) and cART duration (P = .006). Male gender was 99.9% less likely to be related to CMetS using the IDF tool, and the risk of CMetS increased fourfold with each unit increase in waist circumference (P < .001). Triglycerides and blood type "A" have been found to have substantial relationships with CMetS using both techniques. CONCLUSION According to the study, CMetS was found to be common in PLWHA. Age, time on cART, age when cART started, gender, co-morbidities, waist circumference, and diastolic blood pressure were all revealed to be significant predictors of CMetS. Triglycerides and blood type "A" were the only biomarkers found to be significant with CMetS using both the NCEP and IDF tools.

Abstract
Introduction HIV-infection and treatment with antiretroviral therapy (ART) are risk factors for the development of hypertension, which is more prevalent in people living with HIV compared with the general population. Although there is a shift to Integrase Strand Transfer Inhibitor (INSTI)-based ART across the sub-Saharan Africa, there is limited information with regard to INSTIs and hypertension association in this region, making this, a critical question to address. Hence, the study aimed to determine the relationship between hypertension and ART regimen in people living with HIV. Methods this was a cross-sectional study conducted at the Livingstone Central Hospital, southern province of Zambia. This study utilized programmatic data. Demographic and clinical data of 348 persons living with HIV who had been on ART for more than 2 years was abstracted in the adult ART database registry. Descriptive and inferential statistics were used for analyses of data. Results prevalence of hypertension was 18.4% (n=64). Hypertensives were older than normotensives with median (interquartile range) age of 55 (49, 61) and 46 (41, 52), respectively. At multivariate analysis, age (aOR: 1.07, 95% CI 1.04-1.11; p = 0.001) and body mass index (aOR: 1.10, 95% CI 1.04-1.16; p = 0.002) were positively associated with hypertension. Participants on dolutegravir based regimen were 2 times (aOR: 2.44, 95% CI 1.22-4.86; p = 0.01) more likely to be hypertensive compared to those on non-nucleoside reverse transcriptase inhibitors (efavirenz or nevirapine). Conclusion we confirm that increasing age, body mass index (BMI) and use of dolutegravir are risk factors for hypertension. Close monitoring for persons with HIV with these known risk factors is required.

Abstract
We use a regression discontinuity design to estimate the causal effect of antiretroviral therapy (ART) eligibility according to national treatment guidelines of South Africa on two risk factors for cardiovascular disease, body mass index (BMI) and blood pressure. We combine survey data collected in 2010 in KwaZulu-Natal, South Africa, with clinical data on ART. We find that early ART eligibility significantly reduces systolic and diastolic blood pressure. We do not find any significant effects on BMI. The effect on blood pressure can be detected up to three years after becoming eligible for ART.

Abstract
BACKGROUND Evidence regarding the association between HIV viral load (VL) and hypertension is inconsistent. In this study, we investigated the relationship using viremia copy-years (VCY), a cumulative measure of HIV plasma viral burden. METHODS Data were analyzed for 686 PLWH in the Florida Cohort Study, who had at least five years of VL data before the baseline. VL data were extracted from Enhanced HIV/AIDS Reporting System (eHARS) and used to define peak VL (pVL), recent VL (rVL), and undetectable VL (uVL: rVL<50copies/mL). A five-year VCY (log10 copy × years/mL) before the baseline investigation, was calculated and divided into 5 groups (≤2.7, 2.8-3.7, 3.8-4.7, 4.8-5.7 and >5.7) for analysis. Hypertension was determined based on hypertension diagnosis from medical records. Multivariable logistic regression was used for association analysis. RESULTS Of the total sample, 277 (40.4%) participants were hypertensive. Compared to the participants with lowest VCY (≤2.7 log10 copy × years/mL), the odds ratios (OR) and 95% confidence interval [95% CI] for hypertension of the remaining four groups, in order, were 1.91 [1.11, 3.29], 1.91 [1.03, 3.53], 2.27 [1.29, 3.99], and 1.25 [0.65, 2.42], respectively, controlling for confounders. The association was independent of pVL, rVL, and uVL, each of which was not significantly associated with hypertension. CONCLUSION Persistent HIV infection is a risk factor for hypertension among PLWH. Information provided by VCY is more effective than single time-point VL measures in investigating HIV infection- hypertension relationship. The findings of this study support the significance of continuous viral suppression in hypertension prevention among PLWH.

Abstract
INTRODUCTION HIV infected persons are twofold likely to experience a heart attack, stroke, and other forms of Cardiometabolic Syndrome (CMetS). METHODS Electronic searches of databases (MEDLINE and Google Scholar) were queried for articles written in English from 2000 to 2019. RESULTS In this review (16 publications), a total of 14,002 participants from 8 countries were included. Two continents contributed to 62.5% of the CMetS studies while 38.1% from Latin America and 24.4% from North America. The studies were conducted in 113 different centers, with an average study length of 2.8 years. The majority of the study designs were cross-sectional (62%) followed by a cohort study (25%) and clinical trials (12.5%). The mean age of the population enrolled was 41.9 years and 54.6% of the participants were males. The overall prevalence of CMetS using the National Cholesterol Education Adult Treatment Panel definition was 20.6%. Only 31.3% of the studies were reported using the International Diabetes Federation definition. Smoking and high blood pressure were reported as a risk factor in 62.5% of the studies, while diabetes (31.3%), family history of CMetS (25%), and cardiac vascular and cancer diseases were reported in 12.5% of the studies. The average duration of stay with HIV after confirmation was 5.23 + 1.4 (years + SD) and the median duration on HAART was 4.5 + 2.3 (years + SD). CONCLUSIONS CMetS was a common problem among HIV infected persons. Several RFs can contribute to the development of CMetS with smoking and hypertension highly interrelated.

Abstract
INTRODUCTION The prevalence of arterial hypertension (AH) in HIV-patients is highly variable and its association with antiretroviral therapy (ART) is controversial. OBJECTIVE To estimate the prevalence of AH and associated factors in HIV-patients on ART. METHODS This cross-sectional study was conducted in HIV-patients attended in a referral center in Salvador, Brazil. We evaluated clinical, socio-demographic and anthropometric data. Student's ttests or Mann-Whitney's and Pearson's chi-square tests were used to compare the groups. Values of p <0.05 were considered significant. The variables that presented a value of p <0.20 were included in a logistic regression model. RESULTS We evaluated 196 patients (60.7% male) with a mean age of 46.8 ± 11.7 years and a mean body mass index of 24.9 ± 5.3 kg / m2. The median elapsed time since HIV diagnosis and ART use was 11.8 (4.4 - 18.1) and 7.2 (2.7 - 15.3) years, respectively. The prevalence of AH was 41.8%. For individuals > 50 years old, there was a significant association between the increased abdominal circumference and AH and patients ≤ 50 years old presented significant association between AH and overweight, increased abdominal circumference and number of previous ART regimens. After multivariate analysis, age [OR:1.085; 95% CI 1,039 - 1,133], overweight [OR: 4.205; 95% CI 1,841 - 9,606], family history of AH [OR: 2.938; 95% CI 1,253 - 6.885], increased abdominal circumference [OR: 2.774; 95% CI 1.116 - 6.897] and life-time number of ART regimens used [OR: 3.842; 95% CI 1.307 - 11.299] remained associated with AH. CONCLUSION AH was highly prevalent and was associated not only with classical risk factors for arterial hypertension, but also with specific ART regimens.

Abstract
BACKGROUND AND AIM Given the ongoing problems of hypertension and endothelial dysfunction in the HIV population, the primary objective of the study was to assess the cardiovascular, endothelial function, and immune markers in response to rice bran arabinoxylan compound (RBAC) treatment in a sample of HIV+ adults on antiretroviral therapy (ART). STUDY DESIGN A randomized, double-blind placebo-controlled trial of 6 months was used to execute the study. MATERIALS AND METHODS Forty-seven subjects were enrolled and randomly assigned to one of two study conditions (n=22 RBAC and n=25 placebo) for 6 months with assessments at baseline and 3 and 6 months. A multivariate repeated measures analysis of variance model was used to assess the differences between RBAC and placebo groups in cardiovascular (systolic blood pressure), endothelial function (skin blood flow in response to nitric oxide), and immune (CD4+ cell count) markers from baseline to 6 months. RESULTS The effect of treatment (RBAC versus placebo) was significant (Wilks' λ=0.92, F[3, 102]=3.07, P=0.03). The effect of time was significant (Wilks' λ=0.10, F[2, 103]=474.6, P<0.001). The overall interaction between treatment and time was significant (Wilks' λ=0.92, F[2, 103]=4.58, P=0.01). Time contrasts showed that a difference in the overall dependent variable did not occur from baseline to 3 months (F[1, 104]=2.7, P=0.10), marginally occurred from baseline to 6 months (F[1, 104]=3.2, P=0.08), and was significant from 3 to 6 months (F[1, 104]=6.43, P=0.01). CONCLUSIONS The overall significant interaction suggests varying responses in the dependent variables between RBAC and placebo over time, which is being driven by systolic blood pressure, as it decreased in the RBAC group, but increased in the placebo group. In addition, CD4+ manifested a non-significant increase from baseline to 3 months then decreased from 3 to 6 months in the RBAC group, whereas it decreased at 3 months followed by a slight increase at 6 months in the placebo group. Skin blood flow in response to nitric oxide improved non-significantly overall in both groups, but worsened from 3 to 6 months in the placebo group. Thus, RBAC treatment may contribute to modest short-term improvements in systolic blood pressure, endothelial function, and CD4+ cell count, which could help improve the overall health profile of HIV+ adults. RELEVANCE FOR PATIENTS Persons with HIV on ART suffer disproportionately from hypertension and endothelial dysfunction compared to the non-infected population, and conventional medical therapy does not alleviate these issues. RBAC is a safe, low-risk alternative that may help to improve the overall quality of life of these patients through modest improvements in these biomarkers plus CD4+ cell count.

Tinarwo P, Zewotir T, North D. Trends and Adaptive Optimal Set Points of CD4 + Count Clinical Covariates at Each Phase of the HIV Disease Progression. AIDS Res Treat 2020; 2020:1379676. [PMID: 32190387 PMCID: PMC7068150 DOI: 10.1155/2020/1379676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Accepted: 01/21/2020] [Indexed: 11/23/2022] Open
Abstract
In response to invasion by the human immunodeficiency virus (HIV), the self-regulatory immune system attempts to restore the CD4+ count fluctuations. Consequently, many clinical covariates are bound to adapt too, but little is known about their corresponding new optimal set points. It has been reported that there exist few strongest clinical covariates of the CD4+ count. The objective of this study is to harness them for a streamlined application of multidimensional viewing lens (statistical models) to zoom into the behavioural patterns of the adaptive optimal set points. We further postulated that the optimal set points of some of the strongest covariates are possibly controlled by dietary conditions or otherwise to enhance the CD4+ count. This study investigated post-HIV infection (acute to therapy phases) records of 237 patients involving repeated measurements of 17 CD4+ count clinical covariates that were found to be the strongest. The overall trends showed either downwards, upwards, or irregular behaviour. Phase-specific trends were mostly different and unimaginable, with LDH and red blood cells producing the most complex CD4+ count behaviour. The approximate optimal set points for dietary-related covariates were total protein 60-100 g/L (acute phase), <85 g/L (early phase), <75 g/L (established phase), and >85 g/L (ART phase), whilst albumin approx. 30-50 g/L (acute), >45 g/L (early and established), and <37 g/L (ART). Sodium was desirable at approx. <45 mEq/L (acute and early), <132 mEq/L (established), and >134 mEq/L (ART). Overall, desirable approximates were albumin >42 g/L, total protein <75 g/L, and sodium <137 mEq/L. We conclude that the optimal set points of the strongest CD4+ count clinical covariates tended to drift and adapt to either new ranges or overlapped with the known reference ranges to positively influence the CD4+ cell counts. Recommendation for phase-specific CD4+ cell count influence in adaptation to HIV invasion includes monitoring of the strongest covariates related to dietary conditions (sodium, albumin, and total protein), tissue oxygenation (red blood cells and its haematocrit), and hormonal control (LDH and ALP).

Abstract
People living with HIV (PLHIV) are at increased risk for cardiovascular disease (CVD), and immunity against cytomegalovirus (CMV) may be a contributing factor. We hypothesized that enhanced T-cell responses against CMV and CMV-IgG antibody-levels are associated with higher arterial blood pressure in PLHIV. We assessed serum CMV-IgG, systolic- (SBP) and diastolic- (DBP) blood pressure, pulse pressure (PP), traditional risk factors, activated CD8+ T-cells (CD38+HLA-DR+), senescent CD8+ T-cells (CD28-CD57+) and interleukin-6 (IL-6) in 60 PLHIV and 31 HIV-uninfected controls matched on age, gender, education and comorbidity. In PLHIV, expression of interleukin-2, tumor necrosis factor-α and interferon-γ was measured by intracellular-cytokine-staining after stimulation of T-cells with CMV-pp65 and CMV-gB. Associations between CMV-specific immune responses and hypertension, SBP, DBP or PP were assessed by multivariate logistic and linear regression models adjusted for appropriate confounders. The median age of PLHIV was 47 years and 90% were male. Prevalence of hypertension in PLHIV was 37% compared to 55% of HIV-uninfected controls. CMV-specific CD8+ T-cell responses were independently associated with higher PP (CMV-pp65; β = 2.29, p = 0.001, CMV-gB; β = 2.42, p = 0.001) in PLHIV. No significant differences were found with regard to individual measures of SBP and DBP. A possible weak association was found between CMV-IgG and hypertension (β = 1.33, p = 0.049) after adjustment for age, smoking and LDL-cholesterol. HIV-related factors, IL-6, CD8+ T-cell activation or CD8+ T-cell senescence did not mediate the associations, and no associations were found between CMV-specific CD4+ T-cell responses and blood pressure in PLHIV. In conclusion, increased arterial blood pressure in PLHIV may be affected by heightened CMV-specific CD8+ T-cell responses.

Abstract
HIV infection is associated with increased risk and progression of cardiovascular disease (CVD), yet little is known about the prevalence of CVD risk factors among long-term AIDS survivors in resource-limited settings. Using routinely collected data, we conducted a retrospective study to describe the prevalence of CVD risk factors among a cohort of HIV-infected patients followed for over 10 years in Port-au Prince, Haiti. This cohort includes 910 adults who initiated antiretroviral therapy (ART) between 2003 and 2004 and remained in care between 2014 and 2016 when routine screening for CVD risk factors was implemented at a large clinic in Haiti. A total of 397 remained in care ≥10 years and received screening. At ART initiation, 59% were female, median age was 38 years (IQR 33-44), and median CD4 count was 117 cells/mm3 (IQR 34-201). Median follow-up time from ART initiation was 12.1 years (IQR 11.7-12.7). At screening, median CD4 count was 574 cells/mm3 (IQR 378-771), and 84% (282 of 336 screened) had HIV-1 RNA < 1000 copies/mL. Seventy-four percent of patients had at least 1 risk factor including 58% (224/385) with hypertension, 8% (24/297) diabetes, 43% (119/275) hypercholesterolemia, 8% (20/248) active smoking, and 10% (25/245) obesity. Factors associated with hypertension were age (adjusted OR 1.06, P < .001) and weight at screening (adjusted OR 1.02, P = .019). Long-term AIDS survivors have a high prevalence of CVD risk factors, primarily hypertension. Integration of cardiovascular screening and management into routine HIV care is needed to maximize health outcomes among aging HIV patients in resource-limited settings.

Abstract
INTRODUCTION Past endeavours to deal with the obstacle of expensive Cluster of Difference 4 (CD4+) count diagnostics in resource-limited settings have left a long trail of suggested continuous CD4+ count clinical covariates that turned out to be a potentially important integral part of the human immunodeficiency virus (HIV) treatment process during disease progression. However, an evaluation to determine the strongest candidates among these CD4+ count covariates has not been well documented. METHODS The Centre for the AIDS Programme of Research in South Africa (CAPRISA) initially enrolled HIV-negative (phase 1) patients into different study cohorts. The patients who seroconverted (237) during follow-up care were enrolled again into a post-HIV infection cohort where they were further followed up with weekly to fortnightly visits up to 3 months (phase 2: acute infection), monthly visits from 3-12 months (phase 3: early infection) and quarterly visits thereafter (phase 4: established infection) until antiretroviral therapy (ART) initiation (phase 5). The CD4+ count and 46 covariates were repeatedly measured at each phase of the HIV disease progression. A multilevel partial least squares approach was applied as a variable reduction technique to determine the strongest CD4+ count covariates. RESULTS Only 18 of the 46 investigated clinical attributes were the strongest CD4+ count covariates and the top 8 were positively and independently associated with the CD4+ count. Besides the confirmatory lymphocytes, these were basophils, albumin, haematocrit, alkaline phosphatase (ALP), mean corpuscular volume (MCV), platelets, potassium and monocytes. Overall, electrolytes, proteins and red blood cells were the dominant categories for the strongest covariates. CONCLUSION Only a few of the many previously suggested continuous CD4+ count clinical covariates showed the potential to become an important integral part of the treatment process. Prolonging the pre-treatment period of the HIV disease progression by effectively incorporating and managing the covariates for long-term influence on the CD4+ cell response has the potential to delay challenges associated with ART side effects.

Abstract
Data on the burden of hypertension among people living with HIV (PLWH) in Africa are limited, especially after new expert consensus hypertension guidelines were published in 2017. The authors sought to assess the prevalence and factors associated with hypertension among PLWH. This is a cross-sectional study involving PLWH on combination antiretroviral therapy (cART) (n = 250) compared with sex-matched cART-naïve PLWH (n = 201) in Ghana. Hypertension was defined as blood pressure ≥ 140/90 mm Hg or use of antihypertensive drugs. The authors also assessed the prevalence and predictors associated with hypertension using the recent guideline recommended cutoff BP ≥ 130/80 mm Hg. Multivariate logistic regression models were fitted to identify factors associated with hypertension among PLWH. The mean age of PLWH on cART was 45.7 ± 8.6 years, and 42.9 ± 8.8 years among PLWH cART-naive with 81% of study participants being women. The prevalence of hypertension among PLWH on cART and PLWH cART-naïve was 36.9% and 23.4%, P = 0.002 at BP ≥ 140/90 mm Hg and 57.2% and 42.3%, respectively, P = 0.0009, at BP ≥ 130/80 mm Hg. Factors associated with hypertension at BP ≥ 140/90 mm Hg in the PLWH group with adjusted odds ratio (95% CI) were increasing age, 2.08 (1.60-2.71) per 10 years, and body mass index, 1.53 (1.24-1.88) per 5 kg/m2 rise. At BP ≥ 130/80 mm Hg, cART exposure, aOR of 1.77 (95% CI: 1.20-2.63), family history of hypertension, aOR of 1.43 (1.12-1.83), and hypertriglyceridemia, aOR of 0.54 (0.31-0.93), were associated with hypertension. Among PLWH, cART exposure was associated with higher prevalence of hypertension per the new guideline definition, a finding which warrants further investigation and possible mitigation.

Abstract
Purpose: To investigate the variation in CD4 count between HIV positive patients due to clinical covariates at each phase of the HIV disease progression. Patients and methods: The Centre for the AIDS Programme of Research in South Africa (CAPRISA) conducted different studies in which female patients were initially enrolled in HIV negative cohorts (phase 1). Seroconverts were further followed-up weekly to fortnightly visits up to 3 months (phase 2: acute infection), monthly visits from 3 to 12 months (phase 3: early infection), quarterly visits thereafter (phase 4: established infection) until antiretroviral therapy (ART) initiation (phase 5). Results: Eighteen out of the 46 CD4 count covariates investigated were significant. Low average CD4 counts at acute and early phase entry improved at a faster rate than entries at higher average CD4 count. During therapy, all the 18 covariates induced significantly different patients' average CD4 counts. The rate of change of CD4 count greatly varied in response to lactate dehydrogenase during the acute phase. Red blood cells increase resulted in the patients' CD4 counts approaching a common higher level during the early phase. During therapy, the already high CD4 counts improved faster than lower ones in response to the red blood cells increase. As the monocytes increased, patients with lower average CD4 counts became worse than those with higher average CD4 counts. Conclusion: Changes in the covariates measurements either induced no variation effects in certain phases or improved the CD4 count at a faster rate for those patients whose average CD4 was already high or worsen the CD4 level which was already low or caused the patients' CD4 counts to approach the same level - higher or lower than the general cohort. The studied covariates induced wide variations in the CD4 count between HIV positive patients during the ART phase.

Abstract
BACKGROUND Guidelines recommend integrating hypertension screening for HIV-infected adults, but blood pressure measurements may be dynamic around the time of HIV testing. METHODS We measured a seated resting blood pressure in adults (≥18 years) prior to HIV testing, and again after receiving HIV test results, in an ambulatory HIV clinic in KwaZulu-Natal, South Africa. We assessed sociodemographics, smoking, body mass index, diabetes, substance abuse, and anxiety/depression. We used blood pressure categories defined by the Seventh Joint National Committee (JNC 7) classifications, which includes normal, pre-hypertension, stage 1 hypertension, and stage 2 hypertension. RESULTS Among 5,428 adults, mean age was 31 years, 51% were male, and 35% tested HIV-positive. Before HIV testing, 47% (2,634) had a normal blood pressure, 40% (2,225) had prehypertension, and 10% (569) had stage 1 or 2 hypertension. HIV-infected adults had significantly lower blood pressure measurements and less hypertension, as compared to HIV-negative adults before HIV testing; while also having significantly elevated blood pressures after HIV testing. In a multivariable model, HIV-infected adults had a 30% lower odds of hypertension, compared to HIV-uninfected adults (aOR = 0.70, 95% CI: 0.57-0.85). In a separate multivariable model, HIV-infected adults with CD4 ≤200 cells/mm3 had a 44% lower odds of hypertension (aOR = 0.56, 95% CI: 0.38-0.83), as compared to adults with CD4 >200 cells/mm3. The mean arterial blood pressure was 6.5 mmHg higher among HIV-infected adults after HIV testing (p <0.001). CONCLUSIONS HIV-infected adults experienced a transient blood pressure increase after receiving HIV results. Blood pressure measurements may be more accurate before HIV testing and repeated blood pressure measurements are recommended after ART initiation before formally diagnosing hypertension in HIV-infected adults.

Abstract
INTRODUCTION People living with HIV (PLHIV) on antiretroviral therapy (ART) experience high rates of non-communicable diseases (NCDs). These co-morbidities often accumulate and older adults may suffer from multimorbidity. Multimorbidity has been associated with loss of quality of life, polypharmacy, and increased risk of frailty and mortality. Little is known of the trends or predictors NCD multimorbidity in PLHIV in low- and middle-income countries. METHODS We examined NCD multimorbidity in adult PLHIV initiating ART between 2003 and 2014 using a multi-site, observational cohort in Brazil. NCDs included cardiovascular artery disease, hyperlipidemia (HLD), diabetes, chronic kidney disease, cirrhosis, osteoporosis, osteonecrosis, venous thromboembolism and non-AIDS-defining cancers. Multimorbidity was defined as the incident accumulation of two or more unique NCDs. We used Poisson regression to examine trends and Cox proportional hazard models to examine predictors of multimorbidity. RESULTS Of the 6206 adults, 332 (5%) developed multimorbidity during the study period. Parallel to the ageing of the cohort, the prevalence of multimorbidity rose from 3% to 11% during the study period. Older age, female sex (adjusted hazard ratio (aHR) = 1.30 (95% confidence interval (CI) 1.03 to 1.65)) and low CD4 nadir (<100 vs. ≥200 cells/mm3 aHR = 1.52 (95% CI: 1.15 to 2.01)) at cohort entry were significantly associated with increased risk of multimorbidity. Among patients with incident multimorbidity, the most common NCDs were HLD and diabetes; however, osteoporosis was also frequent in women (16 vs. 35% of men and women with multimorbidity respectively). CONCLUSIONS Among adult PLHIV in Brazil, NCD multimorbidity increased from 2003 to 2014. Females and adults with low CD4 nadir were at increased risk in adjusted analyses. Further studies examining prevention, screening and management of NCDs in PLHIV in low- and middle-income countries are needed.

Prevalence, incidence, predictors, treatment, and control of hypertension among HIV-positive adults on antiretroviral treatment in public sector treatment programs in South Africa. PLoS One 2018; 13:e0204020. [PMID: 30281618 PMCID: PMC6169897 DOI: 10.1371/journal.pone.0204020] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 09/01/2018] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND One of the key risk factors for cardiovascular disease is hypertension. Hypertension, which leads to heart attacks and strokes, already affects one billion people worldwide, making it a global public health issue. Incidence and prevalence of the condition is on the rise in low- and middle-income countries, with the biggest increase in sub-Saharan Africa and South Africa at the forefront. We examined the prevalence, incidence, predictors, treatment, and control of hypertension among HIV-positive patients on ART in a large South African observational cohort. METHODS We conducted a prospective study of ART naïve adults initiating ART at a public sector HIV clinic in South Africa between April 2004-2017. Patients with diagnosed hypertension at ART initiation were excluded from the incidence analysis. Log-binomial regression was used to estimate predictors of hypertension at ART initiation, while competing risks regression was used to evaluate the relationship between predictors of incident hypertension, accounting for death as a competing risk. RESULTS Among 77,696 eligible patients, 22.0% had prevalent hypertension at ART initiation. Of the remaining patients with no hypertension at ART initiation, 8,125 incident hypertension cases were diagnosed over the period of follow-up, corresponding to an incident rate of 5.4 per 100 person-years (95% confidence interval (CI): 5.3-5.6). We found patients ≥40 years of age and patients with a body mass index (BMI) ≥25kg/m2 were at increased risk of both prevalent and incident hypertension. Male patients and those with pre-hypertension at ART initiation had increased hazards of hypertension over the period of follow-up. When assessing the choice of antiretroviral drug in first-line ART, patients initiated on nevirapine were at 27% increased risk of developing hypertension compared to those initiated on efavirenz, while patients who initiated on either zidovudine or stavudine had a 40% increased risk of developing hypertension compared to patients initiated on tenofovir. Patientswith poorer health status at ART initiation (i.e. WHO III/IV stage, low CD4 count, low hemoglobin levels and low BMI) had a decrease risk of prevalent hypertension. We found an inverse relationship in patients with a CD4 count <50 cells/mm3 at ART initiation who had a 25% increased risk of incident hypertension compared to those with a CD4 count ≥350 cells/mm3. CONCLUSION Over 20% of patients in our cohort had hypertension at ART initiation, and 13% of those with normal blood pressure at ART initiation developed hypertension while on ART. Older patients, males, those on nevirapine, zidovudine or stavudine, and those who are overweight/obese should be targeted for frequent blood pressure monitoring and the identification of other cardiovascular risk factors to encourage lifestyle modifications. Additionally, these groups should be offered pharmaceutical therapy to help prevent myocardial infarction, heart failure, stroke, and kidney disease. Further research is needed to determine the level of access and adherence to pharmaceutical treatment for hypertension in this population. Additionally, an HIV-negative comparison population is needed to assess the association of the HIV virus itself with hypertension.

Association between exposure to antiretroviral drugs and the incidence of hypertension in HIV-positive persons: the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study. HIV Med 2018; 19:605-618. [PMID: 30019813 PMCID: PMC6169998 DOI: 10.1111/hiv.12639] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/10/2018] [Indexed: 01/10/2023]
Abstract
OBJECTIVES Previous studies have suggested that hypertension in HIV-positive individuals is associated primarily with traditional risk factors such as older age, diabetes and dyslipidaemia. However, controversy remains as to whether exposure to antiretroviral (ARV) drugs poses additional risk, and we investigated this question in the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) cohort. METHODS The incidence of hypertension [systolic blood pressure (BP) > 140 and/or diastolic BP > 90 mmHg and/or initiation of antihypertensive treatment] was determined overall and in strata defined by demographic, metabolic and HIV-related factors, including cumulative exposure to each individual ARV drug. Predictors of hypertension were identified using uni- and multivariable Poisson regression models. RESULTS Of 33 278 included persons, 7636 (22.9%) developed hypertension over 223 149 person-years (PY) [incidence rate: 3.42 (95% confidence interval (CI) 3.35-3.50) per 100 PY]. In univariable analyses, cumulative exposure to most ARV drugs was associated with an increased risk of hypertension. After adjustment for demographic, metabolic and HIV-related factors, only associations for nevirapine [rate ratio 1.07 (95% CI: 1.04-1.13) per 5 years] and indinavir/ritonavir [rate ratio 1.12 (95% CI: 1.04-1.20) per 5 years] remained statistically significant, although effects were small. The strongest independent predictors of hypertension were male gender, older age, black African ethnicity, diabetes, dyslipidaemia, use of lipid-lowering drugs, high body mass index (BMI), renal impairment and a low CD4 count. CONCLUSIONS We did not find evidence for any strong independent association between exposure to any of the individual ARV drugs and the risk of hypertension. Findings provide reassurance that screening policies and preventative measures for hypertension in HIV-positive persons should follow algorithms used for the general population.

Abstract
OBJECTIVES To quantify within a cohort of HIV-infected individuals the number of medical visits and procedures to be carried out according to comorbidities and risk factors to implement a personalized care pathway. PATIENTS AND METHODS Retrospective study of 915 patients consulting from January 1 to December 31, 2016 at an outpatient unit of multidisciplinary consultations, using an electronic patient record. We built an algorithm using parameters required for the application of the national guidelines for the management of HIV-infected individuals. The frequency of comorbidities was measured according to gender, transmission risk group, and nadir CD4 (<or>200/mm3). RESULTS Patients were mostly men (median age: 52 years), of whom 16% were aged≥60 years. Viral load was<40 copies/mL in 93.5% of treated patients and CD4 cell count≥500/mm3 for 73%. Overall, 74.5% of patients had at least one comorbidity. The number of comorbidities was similar in men and women but was significantly higher in patients with a nadir CD4 <200/mm3 and increased with age (irrespective of gender). The minimum number of consultations to be scheduled per year was 8123: 70% for the management of comorbidities with an average of six consultations/year/patient. Overall, 53% of patients should attend a proctology consultation. The minimum number of paramedical procedures to be performed was 5115. CONCLUSION The implementation of a personalized multidisciplinary management within a single facility seems to be a suitable care model to address the needs of HIV-infected individuals.

Abstract
PURPOSE OF REVIEW This review describes what is known concerning the burden of hypertension among people living with HIV (PLHIV), and also addresses relevant topics with respect to its risk factors and clinical management. RECENT FINDINGS Hypertension is highly prevalent in HIV-positive populations, and may be more common than in HIV-negative populations. Risk factors contributing to the development of hypertension in PLHIV include demographic factors, genetic predisposition, lifestyle, comorbidities such as obesity, antiretroviral therapy-related changes in body composition, and potentially also immunodeficiency, immune activation and inflammation, as well as effects from antiretroviral therapy itself. Clinical management of hypertension in PLHIV requires awareness for drug-drug interactions between antiretroviral drugs and antihypertensive drugs. Awareness, treatment, and control of hypertension in PLHIV is currently suboptimal and should be improved. SUMMARY The burden of hypertension among PLHIV is high and its pathophysiology most likely multifactorial. Elucidating the exact pathophysiology of hypertension in PLHIV is vital as this may provide new targets to impact and improve clinical management. In the meantime, efforts should be made to improve hypertension management as per existing clinical guidelines in order to safeguard cardiovascular health and quality of life in PLHIV.

Abstract
Objectives Prevalence of hypertension has not been studied in the Ethiopian HIV-infected population, which represents 60% of the patients in our AIDS unit. Our aim was to identify risk factors and characterize the prevalence of hypertension in the population monitored at our unit. Methods A retrospective chart review categorized subjects according to their blood pressure levels. Hypertension prevalence was determined and stratified according to variables perceived to contribute to elevated blood pressure. Results The prevalence of hypertension in our study population was significantly higher compared to the general population (53% versus 20%, P < 0.0001) and was associated with known risk factors and not with patients' viral load and CD4 levels. Ethiopian HIV-infected adults had a prominently higher rate of blood pressure rise over time as compared to non-Ethiopians (P = 0.016). Conclusions The high prevalence of hypertension in this cohort and the rapid increase in blood pressure in Ethiopians are alarming. We could not attribute high prevalence to HIV-related factors and we presume it is part of the metabolic syndrome. The lifelong cardiovascular risk associated with HIV infection mandates hypertension screening and close monitoring in this population.

Association between CD4 Cell Count and Blood Pressure and Its Variation with Body Mass Index Categories in HIV-Infected Patients. Int J Hypertens 2018; 2018:1691474.

Abstract
The aim of this study was to establish whether an independent relationship exists between CD4 count and hypertension and if this relationship is modified or confounded by the body mass index (BMI). Methods. A secondary data analysis of a cross-sectional study on 200 HIV/AIDS patients at a referral hospital in Cameroon was conducted. Linear and logistic regression models were used as appropriate to explore the association between the variables of interest. Results. There was no linear association between log CD4 count and both systolic (p = 0.200; r = 0.12) and diastolic blood pressures (p = 0.123; r = 0.14), respectively. After adjusting for BMI, patients with CD4 count ≥ 350 cells/μl were more likely to have hypertension than those with CD4 count < 350 cells/μl (AOR: 2.50, 95% CI: 1.05–5.93, and p = 0.032). There was no effect modification from BMI (test of homogeneity, p = 0.721). There was no independent relationship between CD4 count and hypertension after controlling for age, sex, family history of hypertension, BMI-defined overweight, HAART use, and duration of HIV infection (AOR: 1.66, 95% CI: 0.48–5.71, and p = 0.419). Conclusion. This study did not identify any independent relationship between CD4 count and hypertension. Large prospective studies are recommended to better explore this relationship between hypertension and CD4 count.

Abstract
Hypertension is a growing problem in the HIV population. The relationship between low nadir CD4 count and hypertension in the HIV-infected population has been reported. However, the effect of nadir CD4 on hypertension due to a different body mass index (BMI) is yet to be fully elucidated. In this cross-sectional study, 345 HIV-infected participants aged ≥40 years were recruited. They were frequency matched and compared with age, sex, and education with HIV-uninfected adults (n = 345). Hypertension prevalence was lower in HIV-infected than in HIV-uninfected participants (23.8% vs. 31.9%; p = .011), but this association was not significant after adjusting for potential confounders. Among HIV-infected individuals, older age, overweight, with a family history of cardiovascular diseases, and nadir CD4 count <50 cells/μl were independently associated with hypertension. Stratifying individuals with BMI category revealed that nadir CD4 count-regardless if it was operationalized as a dichotomous variable (<50 cells/μl) or continuous variable-was found to be associated with hypertension among individuals who were underweight and obese, but not among those who were normal weight and overweight. Among HIV-uninfected individuals, older age and having a waist circumference above cutoff were significantly associated with hypertension. This is one of the first studies to demonstrate that the association of nadir CD4 and hypertension is observed in underweight and obese HIV-infected patients. While these results suggest that the relationship between nadir CD4 count and hypertension might be mediated by body weight, future longitudinal studies will be needed to validate the findings, including its causal pathways.

Abstract
BACKGROUND Hypertension control is often inadequate in HIV patients. In a contemporary, nationwide cohort of Italian HIV-infected adults, we assessed time trends in hypertension prevalence, awareness, treatment, and control. We also evaluated predictors of cardiovascular events and of new-onset hypertension. METHODS Multicenter prospective cohort study, sampling 961 consecutive HIV patients (71% men, mean age 46 ± 9 years, 30% hypertensive) examined in 2010-2014 and after a median follow-up of 3.4 years. RESULTS Among hypertensive patients, hypertension awareness (63% at baseline and 92% at follow-up), treatment (54 vs. 79%), and control (35 vs. 59%) all improved during follow-up. The incidence of new-onset hypertension was 50.1/1000 person-years (95% confidence interval, 41.2-60.3). Multivariable-adjusted predictors of hypertension were age, BMI, estimated cardiovascular risk, blood pressure, and advanced HIV clinical stage.In total, 35 new cardiovascular events were reported during follow-up (11.1/1000 person-years). In a multivariate model, baseline cardiovascular risk and hypertensive status predicted incident cardiovascular events, whereas a higher CD4 cell count had a protective role. In treated hypertensive patients, the use of integrase strand transfer inhibitors at follow-up was associated with a lower SBP (average yearly change, -3.8 ± 1.6 vs. -0.9 ± 0.5 mmHg in integrase strand transfer inhibitor users vs. nonusers, respectively, P = 0.02). CONCLUSION Hypertension awareness, treatment, and control rates all improved in adult Italian HIV patients over the last few years, although hypertension remains highly prevalent (41%) in middle-aged HIV patients, and significantly impacts cardiovascular morbidity. Traditional risk factors and advanced HIV disease predict new-onset hypertension, whereas CD4 cell count favorably affects future cardiovascular events.

Abstract
OBJECTIVE We compared aortic stiffness between HIV-infected and HIV-uninfected individuals and examined the determinants of vascular aging during HIV infection. METHODS Aortic stiffness using carotid-femoral pulse wave velocity (cf-PWV) was evaluated cross-sectionally between HIV-infected individuals and uninfected controls frequency-matched for age and sex, and longitudinally in a subgroup of HIV-infected individuals. Determinants of elevated cf-PWV levels were assessed using logistic regression. Changes in cf-PWV levels during follow-up (mixed-effect linear regression) and risk factors for achieving cf-PWV below (Group 1) or above the median (Group 2) at last follow-up visit were evaluated only in HIV-infected individuals. RESULTS A total of 133 HIV-infected and 135 HIV-uninfected individuals (mean age: 47.7 ± 8.9 years, 91% men) were enrolled. Median cf-PWV at baseline was similar between HIV-infected individuals and controls [7.5 m/s (interquartile range = 6.7-8.4) vs. 7.5 m/s (interquartile range = 6.6-8.4), respectively; P = 0.64]. In multivariable analysis, only mean arterial pressure showed significant association with elevated cf-PWV in the overall population (P = 0.036). In HIV-infected individuals, elevated cf-PWV was associated with current smoking (P = 0.042), and nadir CD4 T-cell count less than 200 cells/μl (P = 0.048). Ninety-one HIV-infected individuals were followed for a mean 7.6 ± 2.0 years. cf-PWV progression was associated with age (P = 0.018), mean arterial pressure (P = 0.020), and nadir CD4 T-cell count (P = 0.005). Patients from Group 2 had higher baseline waist circumference, pulse pressure, and nadir CD4 T-cell count less than 200 cells/μl. CONCLUSION We observed no difference in aortic stiffness between HIV-infected and controls. Moreover, aortic stiffness aging was independently associated with past severe immunodeficiency, along with other traditional risk factors. Our results call for early antiretroviral initiation.

Abstract
INTRODUCTION HIV infection is associated with an increased risk of cardiovascular disease in connection with atherosclerosis and thromboembolic complications. The pathogenesis of atherosclerosis is still unclear in this group of patients. Studies on pathogenesis of atherosclerosis in the general population emphasize the role of the extrinsic pathway of blood coagulation, particularly the tissue factor (TF) and tissue factor pathway inhibitor (TFPI). The effect of persistent activation of the immune system on enhanced expression of TF on the surface of monocytes in subjects infected with HIV is known to be correlated with the level of HIV RNA in blood serum. STUDY AIM The aim of this study was to evaluate the concentration of TF and its inhibitor TFPI in blood plasma, the impact of traditional and non-traditional cardiovascular risk factors on their concentration and the impact of both markers of haemostasis on the severity of subclinical atherosclerosis as assessed by the intima-media measurement of the carotid artery in HIV infected patients. MATERIALS The study included 121 HIV-infected people with known clinical, immunological and virological status. The control group consisted of 42 healthy individuals, selected in terms of age and sex. RESULTS AND CONCLUSIONS Higher concentrations of TF occurred in HIV-infected patients with a low current plasma HIV RNA level, nadir CD4+ T-cell count and longer duration of cumulative antiretroviral treatment. In multivariate analysis, it was the length of cumulative NRTI treatment that impacted on the concentration of TF. The determinants of cardiovascular disease (CVD) risk factors and inflammatory markers did not show any effect on the concentrations of TF. The TFPI level in HIV-infected patients was significantly higher than in the control group and was negatively correlated with the current level of HIV RNA and nadir CD4+ T-cell count, being higher in patients subjected to antiretroviral treatment. It was shown that the higher the cardiovascular risk and the higher the levels of total cholesterol, low-density lipoprotein cholesterol (LDL) and non-high-density lipoprotein cholesterol (non-HDL), the higher the concentrations of TFPI observed. The levels of TF and TFPI were positively correlated with carotid intima media thickness (cIMT); in the multivariate analysis, TF, non-HDL cholesterol and lifetime smoking (pack-years) independently affected the growth of cIMT. A similar effect on cIMT was demonstrated by TFPI.

Abstract
PURPOSE Non-dipping nocturnal blood pressure (BP) pattern has been reported prevalent among HIV-infected patients and is associated with adverse cardiovascular outcomes. The aims of this observational study were to identify predictors of nocturnal BP decline, and to explore whether diurnal BP profile is associated with alterations in cardiac structure and function. MATERIALS AND METHODS A total of 108 treated HIV-infected patients with suppressed viremia underwent ambulatory BP measurement, 51 of these patients also underwent echocardiography. RESULTS Non-dipping nocturnal BP pattern was present in 51% of the patients. Decreased nocturnal decline in systolic BP (SBP) correlated with lower CD4 count (rsp = 0.21, p = 0.032) and lower CD4/CD8 ratio (rsp = 0.26, p = 0.008). In multivariate linear regression analyses, lower BMI (p = 0.015) and CD4/CD8 ratio <0.4 (p = 0.010) remained independent predictors of nocturnal decline in SBP. Nocturnal decline in SBP correlated with impaired diastolic function, e' (r = 0.28, p = 0.049) as did nadir CD4 count (rsp = 0.38, p = 0.006). In multivariate linear regression analyses, nadir CD4 count <100 cells/μL (p = 0.037) and age (p < 0.001) remained independent predictors of e'. CONCLUSIONS Compromised immune status may contribute to attenuated diurnal BP profile as well as impaired diastolic function in well-treated HIV infection.

Abstract
OBJECTIVES We sought to describe blood pressure (BP) changes after antiretroviral therapy (ART) initiation and evaluate the association of markers of inflammation with incident hypertension in a cohort of HIV-infected individuals in Uganda. METHODS We used mixed effects linear regression to model changes in systolic BP over time among a cohort of HIV-infected individuals initiating ART in Uganda. After exclusion of participants with preexisting hypertension, we identified participants with normal BP throughout follow-up (controls) and those with elevated BP on ≥3 consecutive visits (cases). Before ART initiation, participants had testing for interleukin 6, kynurenine/tryptophan ratio, lipopolysaccharide, soluble CD14, soluble CD163, and D-dimer and those with viral suppression at 6 months during ART had repeat tests. We fit logistic regression models to estimate associations between biomarkers and risk of incident hypertension. RESULTS In the entire cohort, systolic BP increased by 9.6 mm Hg/yr (95% CI: 7.3 to 11.8) in the first 6 months of ART, then plateaued. Traditional factors: male gender (adjusted odds ratio (AOR) 2.76, 95% CI: 1.34 to 5.68), age (AOR 1.09, 95% CI: 1.04 to 1.13), overweight (AOR 4.48, 95% CI: 1.83 to 10.97), and a CD4 count <100 cells (AOR 3.08, 95% CI: 1.07 to 8.89) were associated with incident hypertension. After adjusting for these, D-dimer levels at month 6 were inversely associated with incident hypertension (AOR 0.61, 95% CI: 0.37 to 0.99). Although not significant, similar associations were seen with sCD14 and kynurenine/tryptophan ratio. CONCLUSION BP increases early after ART initiation in Ugandans. Traditional risk factors, rather than immune activation, were associated with incident hypertension in this population.

Abstract
OBJECTIVES Studies of HIV-associated brain atrophy often focus on a priori brain regions of interest, which can introduce bias. A data-driven, minimally biased approach was used to analyze changes in brain volumetrics associated with HIV and their relationship to aging, viral factors, combination antiretroviral therapy (cART), and gender, and smoking. DESIGN A cross-sectional study of 51 HIV-uninfected (HIV-) and 146 HIV-infected (HIV+) participants. METHODS Structural MRI of participants was analyzed using principal component analysis (PCA) to reduce dimensionality and determine topographies of volumetric changes. Neuropsychological (NP) assessment was examined using global and domain-specific scores. The effects of HIV disease factors (eg, viral load, CD4, etc.) on brain volumes and neuropsychological were investigated using penalized regression (LASSO). RESULTS Two components of interest were visualized using principal component analysis. An aging effect predominated for both components. The first component, a cortically weighted topography, accounted for a majority of variance across participants (43.5% of variance) and showed independent effects of HIV and smoking. A secondary, subcortically weighted topography (4.6%) showed HIV-status accentuated age-related volume loss. In HIV+ patients, the cortical topography correlated with global neuropsychological scores and nadir CD4, whereas subcortical volume loss was associated with recent viral load. CONCLUSIONS Cortical regions showed the most prominent volumetric changes because of aging and HIV. Within HIV+ participants, cortical volumes were associated with immune history, whereas subcortical changes correlated with current immune function. Cognitive function was primarily associated with cortical volume changes. Observed volumetric changes in chronic HIV+ patients may reflect both past infection history and current viral status.

Abstract
OBJECTIVES With the increasing impact of cardiovascular disease among populations aging with HIV, contemporary prevalence estimates for predisposing metabolic comorbidities will be important for guiding the provision of relevant lifestyle and pharmacological interventions. We estimated the citywide prevalence of hypertension, type 2 diabetes, dyslipidaemia, and obesity; examined differences by demographic subgroups; and assessed clinical correlates. METHODS Utilizing an electronic medical record (EMR) database from the DC Cohort study - a multicentre prospective cohort study of HIV-infected outpatients - we assessed the period prevalence of metabolic comorbidities between 2011 and 2015 using composite definitions that incorporated diagnoses, pharmacy records, and clinical/laboratory results. RESULTS Of 7018 adult patients (median age 50 years; 77% black), 50% [95% confidence interval (CI) 49-51] had hypertension, 13% (95% CI: 12-14) had diabetes, 48% (95% CI: 47-49) had dyslipidaemia, and 35% (95% CI: 34-36) had obesity. Hypertension was more prevalent among black patients, diabetes and obesity were more prevalent among female and black patients, dyslipidaemia was more prevalent among male and white patients, and comorbidities were more prevalent among older patients (all P < 0.001). For many patients, evidence of treatment for these comorbidities was not available in the EMR. Longer time since HIV diagnosis, greater duration of antiretroviral treatment, and having controlled immunovirological parameters were associated with metabolic comorbidities. CONCLUSIONS These findings underscore the pervasive burden of metabolic comorbidities among HIV-infected persons, serve as the basis for future analyses characterizing their impact on subsequent adverse cardiovascular outcomes, and highlight the need for an increased focus on the prevention and control of comorbid complications in this population.

Abstract
People living with human immunodeficiency virus (HIV) infection and receiving antiretroviral therapy now have the same life expectancy as the general population. However, they have a higher risk of atherosclerotic cardiovascular events because of a complex and polyfactorial vasculopathy, combining the effects of antiretroviral therapy, the HIV virus itself, immune activation, chronic inflammation and metabolic disturbances. Whether people living with HIV infection experience increased vascular aging compared with the general population remains controversial. To summarize current knowledge of the association between HIV infection and aortic stiffness as a marker of vascular aging. This review included 18 clinical studies in adult populations, published between 2009 and 2016, and identified on PubMed/MEDLINE or other databases. Search terms were aortic stiffness, arterial stiffness, vascular aging, pulse wave velocity and HIV. All 18 studies were observational, and compared groups infected (HIV+) and not infected (HIV-) with HIV. Ten studies (55%) reported no significant differences in aortic stiffness between HIV+ groups and age-matched HIV- control groups. The main reported determinants of aortic stiffness were age, blood pressure, smoking, metabolic syndrome and HIV-related variables, including CD4/CD8 ratio, current T-CD4 count < 200/mm3 and nadir T-CD4+ count < 200/mm3. We found discordant results regarding whether HIV+ patients had increased aortic stiffness compared with HIV- controls. However, HIV-related conditions were associated with vascular health. This association has been confirmed in recent prospective studies. There is emerging evidence that HIV itself and immune activity affect vascular health and the large arteries.

Abstract
Background. Elevated blood pressure has been reported among treatment naïve HIV-infected patients. We investigated prevalence of hypertension and its associated risk factors in a HAART naïve HIV-infected population in Dar es Salaam, Tanzania. Methods. A cross-sectional analysis was conducted among HAART naïve HIV-infected patients. Hypertension was defined as systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg. Overweight and obesity were defined as body mass index (BMI) between 25.0-29.9 kg/m2 and ≥30 kg/m2, respectively. We used relative risks to examine factors associated with hypertension. Results. Prevalence of hypertension was found to be 12.5%. After adjusting for possible confounders, risk of hypertension was 10% more in male than female patients. Patients aged ≥50 years had more than 2-fold increased risk for hypertension compared to 30-39-years-old patients. Overweight and obesity were associated with 51% and 94% increased risk for hypertension compared to normal weight patients. Low CD4+ T-cell count, advanced WHO clinical disease stage, and history of TB were associated with 10%, 42%, and 14% decreased risk for hypertension. Conclusions. Older age, male gender, and overweight/obesity were associated with hypertension. Immune suppression and history of TB were associated with lower risk for hypertension. HIV treatment programs should screen and manage hypertension even in HAART naïve individuals.

Abstract
OBJECTIVE The successful scale-up of antiretroviral therapy (ART) in sub-Saharan Africa has led to increasing life expectancy, and thus increased risk of hypertension. We aimed to describe the incidence and predictors of hypertension in HIV patients receiving ART at a publicly funded clinic in rural Uganda. METHODS We abstracted data from medical records of adult patients who initiated ART at an HIV clinic in south-western Uganda during 2010-2012. We defined hypertension as at least two consecutive clinical visits, with a SBP at least 140 mmHg and/or SBP of at least 90 mmHg, or prescription for an antihypertensive medication. We calculated the incidence of hypertension and fit multivariable Cox proportional-hazards models to identify predictors of hypertension. RESULTS A total of 3389 patients initiated ART without a prior diagnosis of hypertension during the observation period. Over 3990 person-years of follow-up, 445 patients developed hypertension, for a crude incidence of 111.5/1000 (95% confidence interval 101.9-121.7) person-years. Rates were highest among men aged at least 40 years (158.8 per/1000 person-years) and lowest in women aged 30-39 years (80/1000 person-years). Lower CD4 cell count at ART initiation, as well as traditional risk factors including male sex, increasing age, and obesity, were independently associated with hypertension. CONCLUSION We observed a high incidence of hypertension in HIV-infected persons on ART in rural Uganda, and increased risk with lower nadir CD4 cell counts. Our findings call for increased attention to screening of and treatment for hypertension, along with continued prioritization of early ART initiation.

Abstract
BACKGROUND Individuals infected with human immunodeficiency virus (HIV) have a higher risk of cardiovascular disease, potentially partly mediated by a higher prevalence of hypertension. We therefore examined the prevalence and determinants of hypertension in HIV-1-infected patients compared with appropriate HIV-negative controls. METHODS Data from 527 HIV-1-infected and 517 HIV-uninfected participants at the time of enrollment into the ongoing AGEhIV Cohort Study were analyzed. Hypertension was defined as systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, and/or self-reported use of antihypertensive drugs. RESULTS Hypertension prevalence was higher among HIV-1-infected individuals compared with controls (48.2% vs 36.4%; odds ratio [OR], 1.63; 95% confidence interval [CI], 1.27-2.09). In logistic regression models adjusted for age, sex, ethnicity, family history of hypertension, smoking, alcohol use, physical activity, and body mass index, the association between HIV and hypertension remained statistically significant (ORHIV, 1.65; 95% CI, 1.25-2.19), but was attenuated after additional adjustment for waist-to-hip ratio (ORHIV, 1.29; 95% CI, .95-1.76). Among HIV-1-infected individuals, particularly among those with mono/dual nucleoside reverse transcriptase inhibitor therapy prior to combination antiretroviral therapy, stavudine exposure was independently associated with hypertension (ORstavudine, 1.54; 95% CI, 1.04-2.30). This association was attenuated after additional adjustment for either waist-to-hip ratio (ORstavudine, 1.30; 95% CI, .85-1.96) or hip circumference (ORstavudine, 1.40; 95% CI, .93-2.11). CONCLUSIONS Our findings suggest that changes in body composition, involving both abdominal obesity and stavudine-induced peripheral lipoatrophy, might contribute to the higher prevalence of hypertension in HIV-1-infected patients.

Abstract
BACKGROUND Persons infected with human immunodeficiency virus (HIV) are at higher risk for major cardiovascular disease (CVD) events than uninfected persons. Understanding the epidemiology of major traditional CVD risk determinants, particularly hypertension, in this population is needed. METHODS The study population included HIV-infected patients participating in the UNC CFAR HIV Clinical Cohort from 1996 to 2013. Annual incidence rates of hypertension were calculated. Multivariable Poisson models were fit to identify factors associated with incident hypertension. RESULTS 3141 patients contributed 21 956 person-years (PY) of follow-up. Overall, 57% patients were black, 28% were women, and the median age was 35 years. Hypertension age-standardized incidence rates increased from 1.68 cases per 100 PYs in 1996 to 5.35 cases per 100 PYs in 2013 (P < .001). In adjusted analyses, hypertension rates were higher among obese patients (incidence rate ratio [IRR] 1.70, 95% confidence interval [CI], 1.43-2.02), and those with diabetes mellitus (IRR 1.44, 95% CI, 1.14-1.83) and renal insufficiency (IRR 1.36, 95% CI, 1.16-1.61), but lower among patients with a CD4 nadir of ≥500 cells/mm(3) (IRR 0.73, 95% CI, .53-1.01). CONCLUSIONS The incidence of hypertension increased from 1996 to 2013, alongside increases in traditional hypertension risk determinants. Notably, HIV-related immunosuppression and ongoing viral replication may contribute to an increased hypertension risk. Aggressive CVD risk factor management, early HIV diagnosis, linkage to care, antiretroviral therapy initiation, and durable viral suppression, will be important components of a comprehensive primary CVD prevention strategy in HIV-infected persons.

Abstract
OBJECTIVE In virologically suppressed HIV-infected adults, noncommunicable diseases (NCDs) have been associated with immune senescence and low CD4/CD8 lymphocyte ratio. Age differences in the relationship between CD4/CD8 ratio and NCDs have not been described. DESIGN Observational cohort study. METHODS We assessed CD4/CD8 ratio and incident NCDs (cardiovascular, cancer, liver, and renal diseases) in HIV-infected adults started on antiretroviral therapy between 1998 and 2012. Study inclusion began once patients maintained virologic suppression for 12 months (defined as baseline). We examined age and baseline CD4/CD8 ratio and used Cox proportional hazard models to assess baseline CD4/CD8 ratio and NCDs. RESULTS This study included 2006 patients. Low baseline CD4/CD8 ratio was associated with older age, male sex, and low CD4 lymphocyte counts. In models adjusting for CD4 lymphocyte count, CD4/CD8 ratio was inversely associated with age (P < 0.01). Among all patients, 182 had incident NCDs, including 46 with coronary artery disease (CAD) events. CD4/CD8 ratio was inversely associated with risk of CAD events [adjusted HR per 0.1 increase in CD4/CD8 ratio = 0.87, 95% confidence interval (CI): 0.76-0.99, P = 0.03]. This association was driven by those under age 50 years (adjusted HR 0.83 [0.70-0.97], P = 0.02) vs. those over age 50 years (adjusted HR = 0.96 [0.79-1.18], P = 0.71). CD4/CD8 ratio was not significantly associated with incident noncardiac NCDs. CONCLUSIONS Higher CD4/CD8 ratio after 1 year of HIV virologic suppression was independently predictive of decreased CAD risk, particularly among younger adults. Advanced immune senescence may contribute to CAD events in younger HIV patients on antiretroviral therapy.

Abstract
BACKGROUND Although human immunodeficiency virus (HIV)-infected persons are at increased risk for major cardiovascular events, short-term prognosis after these events is unclear. METHODS To determine the association between HIV infection and acute myocardial infarction (AMI) and stroke outcomes, we analyzed hospital discharge data from the Nationwide Inpatient Sample (NIS) between 2002 and 2012. Multivariable logistic regression was used to evaluate the association between HIV infection and in-hospital death after AMI or stroke. RESULTS Overall, 18 369 785 AMI/stroke hospitalizations were included in the analysis. Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke (odds ratio, 3.03 [95% confidence interval {CI}, 1.71-5.38] for AMI and 2.59 [95% CI, 1.97-3.41] for stroke). Additionally, patients with AIDS were more likely than HIV-uninfected patients to be discharged to nonhospital inpatient facilities after admission for AMI (OR, 3.14 [95% CI, 1.72-5.74]) or stroke (OR, 1.45; 95% CI, 1.12-1.87). There was a minimal difference in either outcome between HIV-infected patients without a history of AIDS and uninfected patients. CONCLUSIONS Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke. This disparity was not observed when infected patients without a history of AIDS were compared to uninfected patients, implying that preserving immune function may improve cardiovascular outcomes in HIV-infected persons.

Abstract
The chronic inflammation induced by human immunodeficiency virus (HIV) contributes to increased risk of coronary heart disease (CHD) in HIV-infected individuals. HIV-infected patients generally benefit from being treated with antiretroviral drugs, but some antiretroviral agents have side effects, such as dyslipidemia and hyperglycemia. There is general consensus that antiretroviral drugs induce a long-term risk of CHD, although the levels of that risk are somewhat controversial. The intention of this cross-sectional study was to describe the lipid profile and the long-term risk of CHD among HIV-positive outpatients at an HIV treatment clinic in Harare, Zimbabwe. Two hundred and fifteen patients were investigated (females n=165, mean age 39.8 years; males n=50; mean age 42.0 years). Thirty of the individuals were antiretroviral-naïve and 185 had been on antiretroviral therapy (ART) for a mean 3.9±3.4 years. All participants had average lipid and glucose values within normal ranges, but there was a small difference between the ART and ART-for total cholesterol (TC) and high-density lipoprotein (HDL). Those on a combination of D4T or ZDV/NVP/3TC and PI-based ART were on average oldest and had the highest TC levels. Framingham risk showed 1.4% prevalence of high CHD risk within the next ten years. After univariate analysis age, sex, TC/HDL ratio, HDL, economic earnings and systolic BP were associated with medium to high risk of CHD. After multivariate regression analysis and adjusting for age or sex only age, sex and economic earnings were associated with medium to high risk of CHD. There is small risk of developing CHD, during the next decade in HIV infected patients at an HIV treatment clinic in Harare.

Increased systemic immune activation and inflammatory profile of long-term HIV-infected ART-controlled patients is related to personal factors, but not to markers of HIV infection severity. J Antimicrob Chemother 2015; 70:1816-24.

Abstract
OBJECTIVES The objective of this study was to analyse the respective roles of personal factors and HIV infection markers on the systemic immune activation/inflammatory profile of long-term antiretroviral treatment-controlled patients. PATIENTS AND METHODS A panel of soluble immune activation/inflammatory biomarkers was measured in 352 HIV-infected treatment-controlled patients from the APROCO-COPILOTE cohort, all of whom were started on a PI in 1997-99 and had a final evaluation 11 years later, and in 59 healthy controls. RESULTS A total of 81.5% of the patients were male, with the following characteristics: median age 49 years; 620 CD4 cells/mm(3); 756 CD8 cells/mm(3); CD4/CD8 ratio 0.81; BMI 23.0 kg/m(2); waist-to-hip ratio 0.95. Markers of inflammation-high-sensitivity (hs) IL-6 (median and IQR) (1.3 pg/L, 0.7-2.6), hs C-reactive protein (CRP) (2.1 mg/L, 0.9-4.5) and D-dimer (252 ng/mL, 177-374)-were elevated compared with healthy controls (P < 0.001) and strongly related to each other, as were markers of immune activation [soluble (s) CD14 (1356 ng/mL, 1027-1818), β2-microglobulin (2.4 mg/L, 2.0-3.1) and cystatin-C (0.93 mg/L, 0.82-1.1)]. Inflammatory and immune activation markers were also associated with each other. In HIV-infected patients: age was related to D-dimer, β2-microglobulin and cystatin-C levels; being a smoker was related to increased IL-6 and cystatin-C; and BMI and waist-to-hip ratio were related to CRP. Conversely, markers of HIV infection, current CD4 or CD8 values, CD4 nadir, CD4/CD8 ratio, AIDS stage at initiation of PIs, current viral load and duration of ART were not associated with immune activation/inflammation markers. CONCLUSIONS In these long-term treatment-controlled HIV-infected patients, all systemic markers of inflammation and immune activation were increased compared with healthy controls. This was related to demographic and behavioural factors, but not to markers of severity of the HIV infection. Intervention to decrease low-grade inflammation must thus prioritize modifiable personal factors.

Abstract
The widespread access to antiretroviral treatment during the past decades has transformed HIV infection from a lethal disease to a chronic condition, in which the relative burden of non-AIDS-related chronic disorders such as cardiovascular disease, malignancy, renal, liver, and bone disease has increased. The adjusted relative risk for myocardial infarction is reported to be around 2-fold compared to that of the general population, which over time is likely to translate into increased absolute risk in an aging population. Thus, delineating potentially HIV-specific pathogenetic mechanisms is crucial in order to tailor novel strategies for prophylaxis and treatment. This review will focus on advances in the field that possibly link HIV-induced alterations of the gut mucosa and consequent microbial translocation to cardiometabolic risk factors in HIV infection. Recent work suggests that markers of microbial translocation are closely associated with several cardiovascular risk factors such as dyslipidemia, insulin resistance, hypertension, coagulation abnormalities, endothelial dysfunction, and carotid atherosclerosis. Future studies should investigate whether associations between microbial translocation and cardiovascular risk factors will translate into increased risk of acute events, and whether strategies to target gut microbiota and microbial translocation might reduce such a risk.

Abstract
UNLABELLED Abnormal levels of inflammation are associated with cardiovascular disease and mortality in human immunodeficiency virus (HIV)-infected patients. Microbial translocation, which may cause inflammation, is decreased by sevelamer in patients undergoing hemodialysis. In this single-arm study, we evaluated the effects of 8 weeks of sevelamer therapy on 36 HIV-infected subjects who were not receiving antiretroviral therapy. Sevelamer did not significantly change markers of microbial translocation, inflammation, or T-cell activation. During sevelamer treatment, however, levels of soluble tissue factor, low-density lipoprotein (LDL) cholesterol, and oxidized LDL cholesterol decreased significantly, whereas D-dimer levels increased. Thus, in this study population, sevelamer did not reduce microbial translocation but may have yielded cardiovascular benefits. CLINICAL TRIALS REGISTRATION NCT 01543958.
