Abstract
Hypertension is a leading risk factor for morbidity and mortality worldwide. Despite current anti-hypertensive therapies, most individuals with hypertension fail to achieve adequate blood pressure control. Moreover, even with adequate control, a residual risk of cardiovascular events and associated organ damage remains. These findings suggest that current treatment modalities are not addressing a key element of the underlying pathology. Emerging evidence implicates immune cells as key mediators in the development and progression of hypertension. In this Review, we discuss our current understanding of the diverse roles of innate and adaptive immune cells in hypertension, highlighting key findings from human and rodent studies. We explore mechanisms by which these immune cells promote hypertensive pathophysiology, shedding light on their multifaceted involvement. In addition, we highlight advances in our understanding of autoimmunity, HIV and immune checkpoints that provide valuable insight into mechanisms of chronic and dysregulated inflammation in hypertension.

Characterizing blood pressure trajectories in people living with HIV following antiretroviral therapy: A systematic review. HIV Med 2023; 24:1106-1114. [PMID: 37474730 PMCID: PMC10799172 DOI: 10.1111/hiv.13524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 06/19/2023] [Indexed: 07/22/2023]
Abstract
OBJECTIVES The advent of antiretroviral therapy (ART) has reduced AIDS-related morbidity and mortality among people living with HIV (PLWH). Due to increased survival, PLWH have now been found to be at risk of chronic conditions related to ageing, such as cardiovascular disease (CVD). Hypertension is common in PLWH and is a major risk factor for the development of CVD. We conducted a systematic literature review to evaluate the research evidence on longitudinal blood pressure (BP) trajectories following ART initiation in PLWH. METHODS We searched the following databases: PubMed, CINHAL, Scopus, and Web of Science (up to 15 March 2021) for peer-reviewed published studies that reported BP trajectories following ART initiation in PLWH. Three reviewers independently screened all studies by title and abstract. We included articles in English, published up to March 2021, that report office BP trajectories in PLWH initiating ART. A total of 10 publications met our inclusion criteria. Eight studies were prospective cohorts and two were retrospective. RESULTS Nine out of 10 studies in the literature reported an increase in systolic BP (4.7-10.0 mmHg in studies with a follow-up range of 6 months to 8 years, and 3.0-4.7 mmHg/year in time-averaged studies). In addition, four out of 10 studies reported increases in diastolic BP (2.3-8.0 mmHg for a 6 month to 6.8-year follow-up range and 2.3 mmHg/year). CONCLUSION Systolic BP consistently increases while diastolic BP changes are more heterogeneous following ART initiation in PLWH. However, the studies were highly variable with respect to population demographics, ART regimen and duration, and follow-up time. Nevertheless, given the risks of CVD complications, such as stroke, heart failure and myocardial infarction, associated with elevated BP, results highlight the importance of future research in this area. It will be important to better characterize BP trajectories over time, identify the most critical times for interventions to reduce BP, determine the long-term CVD consequences in PLWH with elevated BP, and understand how different ART regimens may or may not influence BP and CVD disease.

Abstract
BACKGROUND Higher nocturnal heart rate and lower nocturnal heart rate variability (HRV) is associated with increased cardiovascular disease mortality. Longitudinal studies on nocturnal HRV in people living with HIV (PLWH) are lacking. METHODS We conducted a 1-year prospective cohort study of adult PLWH and HIV-uninfected community controls in northwestern Tanzania. At enrollment, we collected data on cardiovascular risk factors and tested blood samples for hemoglobin, insulin, CD4 cell count, and C-reactive protein. We measured nocturnal HRV and heart rate at baseline and first-year follow-up. Mixed effect linear regression was used to determine predictors of lower HRV. RESULTS Of the 111 enrolled participants (74 PLWH and 37 HIV-uninfected adults), 57.7% were female and the median age was 40 years. Over 1 year of follow-up, the average nocturnal heart rate was 4.5 beats/minute higher in PLWH ( P = 0.006). In the fully adjusted model (with age, sex, nocturnal heart rate, and diabetes), average nocturnal HRV was 10.5 milliseconds lower in PLWH compared with HIV-uninfected adults ( P = 0.03). Unlike with nocturnal heart rate, nocturnal HRV did not improve after 1 year of ART in PLWH or HIV-uninfected adults (fully adjusted change = -2.5 milliseconds, P = 0.45). Lower educational attainment, lesser pancreatic β-cell function, and anemia were associated with higher HRV. CONCLUSIONS Nocturnal parasympathetic nervous system function was persistently lower in PLWH compared with HIV-uninfected adults even after antiretroviral therapy initiation. Improving nocturnal autonomic nervous system function could be a target for cardiovascular disease prevention in PLWH.

Sex differences in hypertension among people living with HIV after initiation of antiretroviral therapy. Front Cardiovasc Med 2022; 9:1006789. [PMID: 36465432 PMCID: PMC9715396 DOI: 10.3389/fcvm.2022.1006789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Accepted: 10/31/2022] [Indexed: 11/19/2022] Open
Abstract
Background Hypertension is common in people living with HIV (PLWH) on antiretroviral therapy (ART). In the general population and in experimental animal models, the incidence of hypertension is greater in males than in females, especially during the premenopausal period. However, it is not known whether there are sex differences in hypertension associated with HIV and ART, and the factors contributing to incident hypertension among PLWH have not been well characterized. In this study, we aimed to determine the time course, sex differences and factors associated with incident hypertension in PLWH initiating ART. Methods and results We conducted a retrospective study in which we used programmatic data from the ART registry to identify sex differences in the determinants of incident hypertension among PLWH initiating the ART regimen from Livingstone University Teaching Hospital in Zambia and followed for 8 years. Males developed hypertension earlier, 2 years after initiating ART, compared to 6 years in females. In multivariable analysis, increasing age, baseline systolic blood pressure and baseline mean arterial pressure (MAP) were associated with increased risk for developing incident hypertension. Also, participants who switched to the integrase strand transfer inhibitor, dolutegravir (DTG) or the protease inhibitor, lopinavir boosted with ritonavir were 2 and 3 times more likely to develop hypertension when compared to those on non-nucleoside reverse transcriptase inhibitors (NNRTIs). However, these relationships were abrogated by sex, as self-reported male sex was the major contributor in predicting incident hypertension. While none of the factors remained significantly associated with incident hypertension upon multivariate analysis among females, body mass index (BMI), and use of protease inhibitors remained strongly associated with hypertension among males. Conclusion Our results indicate that the use of protease inhibitors and BMI are important predictors of incident hypertension among males. Thus, blood pressure and BMI should be closely monitored, particularly in males living with HIV on protease inhibitors. In addition, identifying specific factors that protect females from developing hypertension early is important but remains to be determined.

Abstract
BACKGROUND Body composition changes may explain the rapid increase in blood pressure (BP) in people with HIV (PWH) during the first year of antiretroviral therapy. METHODS We analyzed data from a cohort of PWH and HIV-uninfected adults from the same communities in Mwanza, Tanzania. Blood pressure (BP, mm Hg) and body composition data were collected at baseline and 12-month follow-up. We used multivariable linear regression to compare BP changes in PWH and HIV-uninfected adults, and the relationship between changes in body composition and changes in BP. RESULTS BP data were available for 640 PWH and 299 HIV-uninfected adults. Sixty-four percent were women and the mean age was 38 years. In PWH, systolic BP (SBP) increased (114-118) whereas SBP decreased (125-123) in HIV-uninfected participants. Fat mass increased by 1.6 kg on average in PWH and was strongly associated with the change in BP (P < 0.001). The greater increase in SBP in PWH was partly explained by the lower baseline SBP but PWH still experienced a 2.2 (95% CI: 0.3-4.2) greater increase in SBP after adjustment. Weight gain partially mediated the relationship between HIV and SBP increase in PWH; a 1-kg increase in fat mass accounted for 0.8 (95% CI: 0.6-1.1) increase in SBP. CONCLUSIONS Weight and fat mass increase rapidly in PWH during the first 12 months of antiretroviral therapy and contribute to a rapid increase in SBP. Interventions to prevent excessive increase in fat mass are needed for PWH.

Abstract
OBJECTIVE Arterial stiffness is a known indicator for cardiovascular disease. However, the factors that lead to arterial stiffening have primarily been studied in participants from high-income countries. Here, we examine clinical and lifestyle metrics in relation to arterial stiffness in Tanzanian adults. METHODS We performed pulse wave velocity (PWV), the gold standard measure of arterial stiffness, on 808 Tanzanian adults (ages 18-65) enrolled in a longitudinal cohort studying trends in blood pressure. RESULTS As expected, PWV was strongly associated with age, blood pressure and sex. We controlled for these factors in our statistical analysis. Lifestyle metrics were compared across multiple PWV quantiles. We found that determinants of PWV varied by sex: in female participants, PWV was associated with common obesity metrics and menopause, while in male participants, PWV was associated with HIV status and duration of anti-retroviral therapy (ART). Further clinical and lifestyle factors such as marriage status and type of occupation were also significantly associated with PWV and moderated by sex. CONCLUSION Together, our data demonstrate the importance of studying sex-specific causal pathways for arterial stiffness and of including under-represented populations in these studies.

Abstract
People with HIV (PWH) have a >2-fold greater risk for development of cardiovascular disease (CVD), which may be associated with abnormalities in 24-h ambulatory blood pressure measurement (ABPM) profile. We conducted a nested case-control study of ABPM in 137 PWH and HIV-uninfected controls with normal and high clinic blood pressure (BP) in Tanzania. Nocturnal non-dipping of heart rate (HR) was significantly more common among PWH than HIV-uninfected controls (p = .01). Nocturnal non-dipping of BP was significantly more common in PWH with normal clinic BP (p = .048). Clinical correlates of nocturnal non-dipping were similar in PWH and HIV-uninfected adults and included higher BMI, higher CD4+ cell count, and high C-reactive protein for HR and markers of renal disease for BP. In conclusion, nocturnal non-dipping of both BP and HR was more common in PWH but further research is needed to determine causes and consequences of this difference.

Abstract
Elevated cardiovascular risk including stroke, heart failure, and heart attack is present even after normalization of blood pressure in patients with hypertension. Underlying immune cell activation is a likely culprit. Although immune cells are important for protection against invading pathogens, their chronic overactivation may lead to tissue damage and high blood pressure. Triggers that may initiate immune activation include viral infections, autoimmunity, and lifestyle factors such as excess dietary salt. These conditions activate the immune system either directly or through their impact on the gut microbiome, which ultimately produces chronic inflammation and hypertension. T cells are central to the immune responses contributing to hypertension. They are activated in part by binding specific antigens that are presented in major histocompatibility complex molecules on professional antigen-presenting cells, and they generate repertoires of rearranged T-cell receptors. Activated T cells infiltrate tissues and produce cytokines including interleukin 17A, which promote renal and vascular dysfunction and end-organ damage leading to hypertension. In this comprehensive review, we highlight environmental, genetic, and microbial associated mechanisms contributing to both innate and adaptive immune cell activation leading to hypertension. Targeting the underlying chronic immune cell activation in hypertension has the potential to mitigate the excess cardiovascular risk associated with this common and deadly disease.

Abstract
OBJECTIVE Better understanding of glucose metabolism in patients with HIV after initiating antiretroviral therapy (ART) is important to target treatment and follow-up for diabetes risk and other non-communicable diseases in resource-limited settings. The aim of this study was to assess the changes and predictors of glucose metabolism and blood pressure among patients with HIV on ART for 12 months. METHODS One-year follow-up of Ethiopian patients with HIV after initiation of ART was done. Outcomes were changes in fasting plasma glucose (FPG), and 30-minute (30mPG) and 2-hour plasma glucose (2hPG) after oral glucose tolerance test, glycated haemoglobin (HbA1c), fasting plasma insulin (p-insulin), homeostatic model assessment index for insulin resistance (HOMA-IR) and blood pressure. RESULTS: The mean age was 33 years, and the majority were women. During the first 12 months, levels of all plasma glucose parameters decreased, while p-insulin (10B 3.1; 95% CI2.4, 4.0), HOMA-IR (10B 3.1; 95% CI2.3, 4.0) and systolic blood pressure (B 4.0; 95% CI2.5, 5.5) increased. Fat-free mass at baseline predicted higher increments in p-insulin, HOMA-IR and blood pressure; whereas, fat mass predicted higher increment in HbA1c. CONCLUSIONS Among Ethiopian patients with HIV, blood pressure and insulin increased, and all glucose parameters declined during 12-month of ART. Only longer-term follow-up will tell us whether insulin increase is due to insulin resistance or from recovering β-cells.
