[PMID: 38259850 PMCID: PMC10800701 DOI: 10.3389/fmed.2023.1277059] [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: 08/15/2023] [Accepted: 12/07/2023] [Indexed: 01/24/2024] Open
Abstract
Background The newly approved third-generation oral anti-HIV-1 drug, ainuovirine (ANV), was used in combination with nucleoside reverse transcriptase inhibitors (NRTIs) in our study, and its effects on the lipid profile of antiretroviral-experienced HIV/AIDS patients are unclear. Objectives This study aimed to examine the effects of antiretroviral agents on the lipid profile in patients with HIV/AIDS. Methods We conducted a real-world prospective study involving treatment-naive and treatment-experienced adult participants living with HIV-1 infection provided with ANV- or efavirenz (EFV)-based regimens. The primary endpoint was the proportion of participants with an HIV-1 RNA level of <50 copies/mL at week 24 of treatment. Secondary endpoints included the change from baseline in CD4+ T-cell count and lipid profile. Results A total of 60 treatment-naive and 47 treatment-experienced participants received an ANV-based regimen, while 88 treatment-naive and 47 treatment-experienced participants receiving an EFV-based regimen were, respectively, matched as controls. At week 24 following treatment, the proportion of participants with an HIV-1 RNA level of <50 copies/mL and the mean changes of CD4+ T-cell counts from baseline were significantly higher in naive-ANV group than those in naive-EFV group (p < 0.01). Compared with the EFV group, both naive and experienced ANV groups exhibited a favorable lipid profile, including constant changes in total cholesterol and triglycerides, a significant decrease in LDL-cholesterol (p < 0.0001), and a dramatic increase in HDL-cholesterol (p < 0.001). Conclusion The efficacy of ANV was non-inferior to EFV when combined with two NRTIs. Patients receiving ANV-based regimens had a decreased prevalence of dyslipidemia.

Abstract
Human immunodeficiency virus (HIV) has been generally considered as a highly adaptive and rapidly evolving virus. It still constitutes a major public health problem all over the world despite an effective outcome in the prevention and reversal of the development and prognosis by using antiretroviral therapy. The salient question lies in the more frequent emergence of a series of comorbidities along with the prolongation of the life, which deeply affects the survival in such group. Venous thromboembolism (VTE) has been recognized to be the third most common cardiovascular condition within people living with HIV (PWH). In terms of its mechanism of action, the occurrence of VTE is quite multifactorial and complex in HIV. Prior exploration concerning the etiology of VTE in PWH identifies general, disease-specific, and miscellaneous factors for explaining its occurrence and development. VTE has constituted an important role in PWH and may increase its all-cause mortality. Therefore, it is quite necessary to understand VTE from the following aspects of epidemiology, pathophysiology, molecular mechanisms, and therapeutic interventions so as to balance the risks and benefits of anticoagulation and optimize corresponding treatment.

Abstract
BACKGROUND Studies from high-income countries have reported that even after receiving antiretroviral treatment (ART), HIV-infected adults may not achieve normal levels of certain inflammatory markers that are known to be associated with the onset and development of non-communicable diseases. OBJECTIVE The aim of this study is to examine the relationship between ART and markers of systemic inflammation in HIV/AIDS patients at an urban antiretroviral clinic in Ghana. METHODS We examined serum levels of high sensitivity CRP (hsCRP), interleukin-6 (IL-6), interleukin- 18(IL-18), and tumor necrosis factor-α (sTNFR1 and sTNFR2) from 40 HIV infected patients. Kruskal-Wallis Test was used to examine the differences in markers of systemic inflammation according to the types of ART medication taken. We then utilized generalized additive models (GAM) with non-linear function to examine the association between ART and markers of systemic inflammation after adjusting for potential confounders. RESULTS Overall, 30 (75.0%) of the participants received ART and 35 (85%) were female. Kruskal- Wallis Test revealed no significant differences in the markers of systemic inflammation among the three categories of ART (none, AZT, 3TC, EFV/NVP, and TDF, 3TC/FTC, EFV/NVP). In the multivariable- adjusted GAM model, we found a significant but non-linear association between time since diagnosis and CRP levels (p=0.006). CONCLUSION Although the relatively small sample size limits the scope of the study's findings, these results suggest that individuals on ART need to be screened periodically for the development of chronic conditions. This line of investigation has the potential to influence treatment and clinical guidelines that will improve the quality of care for HIV-infected patients.

Abstract
Combinatorial antiretroviral therapy (cART) suppresses HIV replication to undetectable levels and has been effective in prolonging the lives of HIV infected individuals. However, cART is not capable of eradicating HIV from infected individuals mainly due to HIV’s persistence in small reservoirs of latently infected resting cells. Latent infection occurs when the HIV-1 provirus becomes transcriptionally inactive and several mechanisms that contribute to the silencing of HIV transcription have been described. Despite these advances, latent infection remains a major hurdle to cure HIV infected individuals. Therefore, there is a need for more understanding of novel mechanisms that are associated with latent infection to purge HIV from infected individuals thoroughly. Caveolin 1(Cav-1) is a multifaceted functional protein expressed in many cell types. The expression of Cav-1 in lymphocytes has been controversial. Recent evidence, however, convincingly established the expression of Cav-1 in lymphocytes. In lieu of this finding, the current review examines the potential role of Cav-1 in HIV latent infection and provides a perspective that helps uncover new insights to understand HIV latent infection.

Abstract
BACKGROUND Antiretroviral therapy (ART) is associated with lipid abnormalities that contribute to increased risk of cardiovascular (CV) events among patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). Although disorders of lipid metabolism associated with ART have been described before in developed countries, data on lipid profile disorders associated with ART use in China are limited. This study aimed to examine the changes in lipid profile among patients with HIV/AIDS who initiated lopinavir/ritonavir LPV/r or efavirenz (EFV)-based antiretroviral treatment regimens, which continue to be widely used China and other developing countries. METHODS This is a retrospective, matched case-control study of HIV-positive patients initiating either LPV/r or EFV regimens at the Beijing You'an Hospital, Capital Medical University between July 2012 and January 2017. Generalized estimating equations were used to compare the differences in total cholesterol [TC], triglycerides [TG], low-density lipoprotein-cholesterol [LDL-C], and highdensity lipoprotein-cholesterol [HDL-C] at baseline and up to 24-months after ART initiation between the two treatment arms. RESULTS Baseline characteristics, including age, sex, CD4 cell count, viral load, and serum lipids, which were comparable between the two groups. The LPV/r-based regimen group had increased TC, TG, HDL-C, and LDL-C after 24-months of treatment. In the EFV-regimen group, TC, HDL-C, and LDL-C were increased compared to baseline, while the TC/HDL-C ratio decreased, and TG did not change significantly. After 24-months of treatment, the percentage of patients with dyslipidemia in the LPV/r group was much higher than in the EFV group (84.0% vs. 52.6%, P<0.001), and 17(10%) patients on LPV/r-based regimens had severe dyslipidemia. Patients on LPV/r-based regimens were at increased odds of hypercholesterolemia (odds ratio [OR]=1.709, P=0.038), hypertriglyceridemia (OR=4.315, P<0.001), and high TC/HDL-C ratio (OR=1.951, P=0.003). However, no significant difference was found in HDL-C (OR=1.246, P=0.186) or LDL-C (OR=1.253, P=0.410) between the treatment groups. CONCLUSION Both LPV/r or EFV treatment regimens impacted patients' lipid profiles. Compared to EFV-based regimens, patients on LPV/r-based regimens had increased odds of dyslipidemia, such as hypercholesterolemia, hypertriglyceridemia, or high TC/HDL-C ratio; however, there was no obvious effect on LDL-C, which is more relevant to the development of the cardiovascular disease.

Abstract
Background Recent evidence suggests that HIV infection, even with treatment, increases the risk of coronary heart disease (CHD) and that both chronic inflammation and traditional risk factors play key roles in HIV-associated CHD. Subjects and Methods Patients (N=152), attending Harare HIV clinic, 26% of them male and 82% of them on antiretroviral therapy (ART), were studied. Inflammatory markers comprising of cytokines such as pro-inflammatory tumor necrosis factor-α, (TNF-α), anti-inflammatory interleukin 10, (IL-10) and highly sensitive C reactive protein (hsCRP) together with lipids were assayed using enzyme linked immunosorbent assay (ELISA), immuno-turbidimetric and enzymatic assays, respectively. Correlation analysis of inflammatory markers versus lipid profiles was carried out using bivariate regression analysis. Results Anti-inflammatory cytokine IL-10 and inflammatory hsCRP levels were elevated when measured in all the HIV positive patients, while TNF-α and lipid levels were within normal ranges. Pro-inflammatory TNF-α was significantly higher in ART-naive patients than ART-experienced patients, whereas the reverse was observed for anti-inflammatory IL-10 and anti-atherogenic HDL-C. Correlation analysis indicated a significant positive linear association between IL-10 and total cholesterol (TC) levels but no other correlations were found. Conclusion High cytokine ratio (TNF-α/IL-10) indicates higher CHD risk in ART-naive patients compared to the ART-exposed. The CHD risk could be further strengthened by interplay between inflammatory markers and high prevalence of low HDL-C. Lack of correlation between pro-inflammatory markers (hsCRP and TNF-α) with lipid fractions and correlation between anti-inflammatory IL-10 with artherogenic TC were unexpected findings, necessitating further studies in future.

Abstract
Background Sub-Saharan Africa (SSA) has confronted decades of the HIV epidemic with substantial improvements in access to life-saving antiretroviral therapy (ART). Now, with improved survival, people living with HIV (PLWH) are at increased risk for non-communicable diseases (NCDs), including atherosclerotic cardiovascular disease (CVD). We assessed the existing literature regarding the association of CVD outcomes and HIV in SSA. Methods We used the PRISMA guidelines to perform a systematic review of the published literature regarding the association of CVD and HIV in SSA with a focus on CVD surrogate and clinical outcomes in PLWH. Results From January 2000 until March 2017, 31 articles were published regarding CVD outcomes among PLWH in SSA. Data from surrogate CVD outcomes (n = 13) suggest an increased risk of CVD events among PLWH in SSA. Although acute coronary syndrome is reported infrequently in SSA among PLWH, limited data from five studies suggest extensive thrombus and hypercoagulability as contributing factors. Additional studies suggest an increased risk of stroke among PLWH (n = 13); however, most data are from immunosuppressed ART-naïve PLWH and thus are potentially confounded by the possibility of central nervous system infections. Conclusions Given ongoing gaps in our current understanding of CVD and other NCDs in PLWH in SSA, it is imperative to ascertain the burden of CVD outcomes, and to examine strategies for intervention and best practices to enhance the health of this vulnerable population.

Abstract
The use of highly active antiretroviral therapy has resulted in changes of comorbidity profile in people living with HIV (PLHIV), increasing non-AIDS-related events. The occurrence of cardiovascular events is greater in PLHIV, but the mechanism responsible for it is still controversial. This article aimed to investigate factors associated with the progression to cardiovascular events in PLHIV using HAART. A 15-years cohort study with 1135 PLHIV was conducted in Rio de Janeiro-Brazil. Clinical progression was stratified in five states: No comorbidities (s1), arterial hypertension (s2), lipid abnormalities (s3), hypertension and lipid abnormalities (s4) and major cardiovascular events (stroke, coronary artery disease, thrombosis or death) (s5). Semi-Markov models evaluated the effects of cardiovascular traditional factors, treatment and clinical covariates on transitions between these states. Hazard Ratios (HR) and 95% confidence intervals (CI) were provided. In addition to traditional factors (age, sex, educational level and skin color), the development of one comorbidity (lipid abnormalities or hypertension) increased in patients with low nadir CD4 (<50 cells/mm3), (HR = 1.59, CI 1.11-2.28 and 1.36, CI 1.11-1.66, respectively). The risk to experience a second comorbidity (s3→s4) increased 75% with low nadir CD4. Age was the only factor that increased the risk of major cardiovascular events once having lipid abnormalities with or without hypertension (s3,s4→s5). The prolonged use of certain antiretroviral drugs (abacavir, didanosine, ritonavir, lopinavir, amprenavir and fosamprenavir) increased the risk of direct transition (s1→s5) to major cardiovascular events (HR = 5.29, CI 1.16-24.05). This analysis suggests that prolonged use of certain antiretroviral drugs led directly to major cardiovascular events, while low nadir CD4 only affected the occurrence of lipid abnormalities and hypertension. Management strategies, including rational use of complex exams (such as, computed-tomography angiography), statins and antihypertensives, should be developed based on the distinct roles of antiretroviral use and of HIV infection itself on the progression to cardiovascular events.

Abstract
Dyslipidemia, hypertension, inflammation, and coronary heart disease (CHD) are adverse events in human immunodeficiency virus (HIV)-infected patients even if they are receiving antiretroviral therapy (ART). Yet, data on CHD risk induced by HIV or ART in sub-Saharan Africa are limited. The aim of this longitudinal study was to describe changes in CHD risk profiles measured by lipids, inflammatory markers, and Framingham scores among HIV-positive patients previously reported from Harare, Zimbabwe. Patients were grouped into ART-experienced patients (n=147) and ART-naïve patients (n=23) and followed up for 9 months. Generalized least squares random-effects modeling was applied to explain changes in total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein, TC/HDL ratio, myeloperoxidase, highly sensitive C-reactive protein, and Framingham scores over the 9-month period. Independent variables included age, sex, monthly earning, body mass index, systolic blood pressure (SBP), diastolic blood pressure, duration of HIV diagnosis, duration of ART, viral load, and CD4 count. In ART-experienced patients, there was a substantial decrease in TC over time, ART-negative patients showed a significant increase in TC and HDL over time, and the increase in TC was associated with high viral load and low duration of HIV diagnosis, while increase in HDL was associated with young age, low body mass index, and low SBP. Framingham risk scores increased with time in ART-positive patients, and the change was positively correlated with age, sex, high SBP, and low HDL. There was no association between calculated CHD risk (TC/HDL ratio or Framingham score) and changes in levels of inflammatory markers (myeloperoxidase and highly sensitive C-reactive protein) in any of the patient groups. In conclusion, ART-experienced HIV-positive patients show changes in lipid values over time that makes it necessary to include lipid monitoring in order to reduce any risk of long-term CHD.

Abstract
BACKGROUND Cardiovascular disease (CVD) is an emerging concern for HIV-infected patients. Hyperlipidaemia is a risk factor for CVD and a complication of protease-inhibitor-based antiretroviral therapy, but little is known about its incidence and risk factors in treated patients in resource-limited settings (RLS). METHODS We conducted a secondary analysis of ACTG A5230 trial in which HIV-infected adults from India, Malawi, Tanzania, Thailand and South Africa, with virological relapse on first-line therapy were initiated on lopinavir/ritonavir (LPV/r) monotherapy. Hyperlipidaemia was a grade 2+ elevated fasting total cholesterol (FTC≥240 mg/dl) or fasting triglycerides (FTG≥500 mg/dl) or calculated low-density lipoprotein cholesterol (LDL≥160 mg/dl) based on measurements at weeks 12, 24, 48, 68 and 104. We evaluated factors potentially associated with quantitative lipid changes from baseline to week 12. These were age, sex, race, site and baseline body mass index, CD4+ T-cell count, HIV-1 RNA level and lipids. RESULTS 106 participants without hyperlipidaemia at baseline started LPV/r; median age 39 years, 68% Black African, 55% female. The cumulative incidence of hyperlipidaemia at week 104 was 48% (95% CI 36, 58%). At week 12, there were significant mean increases from baseline in FTC (17 mg/dl, P<0.001) and FTG (104 mg/dl, P<0.001). In multivariable analysis, higher baseline FTC (P=0.044), FTG (P=0.025), Thai (P<0.001) or Indian sites (P=0.020) versus African sites were associated with increased risk of hyperlipidaemia. CONCLUSIONS In HIV-infected adults in RLS initiating LPV/r, hyperlipidaemia was common. Baseline lipid measurements and routine monitoring should be recommended in individuals starting LPV/r-based treatments with borderline high lipids.

Abstract
Background: Dyslipidemia does not occur in all HIV-infected or antiretroviral therapy-experienced patients suggesting role of host genetic factors but there is paucity of data on association between dyslipidemia and gene polymorphisms in Zimbabwe. Objective: To determine association of lipoprotein levels and apolipoprotein B polymorphisms in HIV-infected adults. Method: Demographic data were collected from 103 consenting patients; lipoprotein levels were determined and blood samples were successfully genotyped for both apolipoprotein B 2488C>T Xba1 and apolipoprotein B 4154G>A p.Gln4154Lys EcoR1 polymorphisms by real time polymerase chain reaction. Results: Mean age of genotyped patients was 40.3 ± 10.1 years, 68% were female; prevalence of dyslipidemia was 67.4%. Of 103 samples genotyped for apolipoprotein B Xba1 polymorphism, 76 (74%) were homozygous C/C, 24 (23%) were heterozygous C/T and only three (3%) were homozygous T/T. Apolipoprotein B EcoR1 polymorphism showed little variability, one participant had rare genotype A/A, 68.3% had wild type genotype G/G. Conclusion: Observed frequencies of apolipoprotein B XbaI and EcoRI polymorphisms matched other African studies. In spite of low numbers of rare variants, there was positive association between both total cholestrol and high density lipoprotein with ECoR1 wild type G/G genotype, suggesting that ECoRI 4154 G allele could be more protective against coronary heart disease than EcoR1 4154 A allele. There is need for further research at population level to confirm whether apolipoprotein B ECoR1 genotyping is useful for predicting risk of dyslipidemia in HIV patients in our setting.

Changes in Lipid Profiles of HIV(+) Adults over Nine Months at a Harare HIV Clinic: A Longitudinal Study. Biochem Res Int 2016; 2016:3204818. [PMID: 27051532 PMCID: PMC4802011 DOI: 10.1155/2016/3204818] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Revised: 01/12/2016] [Accepted: 02/08/2016] [Indexed: 12/01/2022] Open
Abstract
HIV infection, together with ART, is associated with changes in biochemical, metabolic parameters and lipid profiles. The aim of this study was to compare changes in lipid profiles among HIV positive outpatients over nine months. 171 patients were investigated, 79% were ART experienced, and 82% of ART experienced patients were on NVP/EFV first line at baseline, but some patients changed ART groups over follow-up and classification was based on intent to treat. More than 60% ART naïve and ART experienced patients had some form of dyslipidemia either at baseline or at follow-up, but mean lipid values for the two groups were within normal limits. At baseline and follow-up, mean levels of TC and HDL were slightly higher in the ART experienced group. Interestingly, there was higher increase in HDL over time in the ART negative group compared to the ART positive group. There was a decrease in TC/HDL ratio in both groups over time, suggesting a reduction in calculated risk of CHD over time. HIV positive patients frequently show various forms of dyslipidemia, but there are no changes in average atherogenic lipid levels and results suggest reduced risk of CHD, mainly due to increases in HDL, after nine months of observation time.

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.
