Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9), a well-known regulator of cholesterol metabolism and cardiovascular diseases, has recently garnered attention for its emerging involvement in cancer biology. The multifunctional nature of PCSK9 extends beyond lipid regulation and encompasses a wide range of cellular processes that can influence cancer progression. Studies have revealed that PCSK9 can modulate signaling pathways, such as PI3K/Akt, MAPK, and Wnt/β-catenin, thereby influencing cellular proliferation, survival, and angiogenesis. Additionally, the interplay between PCSK9 and cholesterol homeostasis may impact membrane dynamics and cellular migration, further influencing tumor aggressiveness. The central role of the immune system in monitoring and controlling cancer is increasingly recognized. Recent research has demonstrated the ability of PCSK9 to modulate immune responses through interactions with immune cells and components of the tumor microenvironment. This includes effects on dendritic cell maturation, T cell activation, and cytokine production, suggesting a role in shaping antitumor immune responses. Moreover, the potential influence of PCSK9 on immune checkpoints such as PD1/PD-L1 lends an additional layer of complexity to its immunomodulatory functions. The growing interest in cancer immunotherapy has prompted exploration into the potential of targeting PCSK9 for therapeutic benefits. Preclinical studies have demonstrated synergistic effects between PCSK9 inhibitors and established immunotherapies, offering a novel avenue for combination treatments. The strategic manipulation of PCSK9 to enhance tumor immunity and improve therapeutic outcomes presents an exciting area for further investigations. Understanding the mechanisms by which PCSK9 influences cancer biology and immunity holds promise for the development of novel immunotherapeutic approaches. This review aims to provide a comprehensive analysis of the intricate connections between PCSK9, cancer pathogenesis, tumor immunity, and the potential implications for immunotherapeutic interventions.

Abstract
The advent of antiretroviral therapy has markedly improved the life expectancy of individuals with HIV, leading to a shift in clinical focus from managing opportunistic infections to addressing chronic conditions, such as atherosclerotic cardiovascular disease (ASCVD). Emerging evidence highlights an elevated risk of ASCVD among people living with HIV, characterized by a higher incidence of acute myocardial infarction, ischemic stroke, and heart failure compared with the general population. This review examines the epidemiology, pathophysiology, and management of ASCVD in the context of HIV. It explores the interplay between HIV infection, antiretroviral therapy, and traditional cardiovascular risk factors, underscoring the need for comprehensive cardiovascular risk reduction strategies tailored to people living with HIV. Through synthesizing data from clinical trials, observational studies, and basic research, the review aims to enhance understanding of HIV-associated ASCVD and inform healthcare practices to improve the longevity and quality of life for this patient population.

Abstract
BACKGROUND The Integration of cardiovascular disease SCreening and prevention in the HIV MAnagement plan for women of reproductive age study set out to determine the effectiveness of screening and lifestyle modification in modifying cardiovascular disease (CVD) risk factors in women living with HIV (WLHIV). METHODS In this prospective, quasiexperimental, intervention study, WLHIV aged 18-<50 years were enrolled from 2 clinics (intervention [I-arm]) and (control arms [C-arm]) in Umlazi, South Africa, between November 2018 and May 2019. Women in the I-arm received lifestyle modification advice on diet, physical activity, alcohol use, and smoking cessation and underwent annual screening for CVD risk. The CVD risk factors were assessed through standardized questionnaires and clinical and laboratory procedures at baseline and at end of 3 years of follow-up. Prevalence of metabolic syndrome and other CVD indices were compared between arms at end-of-study (EOS). RESULTS Total of 269 WLHIV (149 I-arm and 120 C-arm) with a mean ± SD age of 36 ± 1 years were included in the EOS analyses after 32 ± 2 months of follow-up. The metabolic syndrome prevalence at EOS was 16.8% (25/149) in the I-arm and 24% (24/120) in the C-arm (risk ratio 0.9; 95% CI: 0.5 to 1.1; P 0.86). Proportion of women with fasting blood glucose >5.6 mmol/L in the I-arm and C-arm were 2.7% (4/149) and 13.3% (16/120) respectively (risk ratio 0.2; 95% CI: 0.069 to 0.646; P < 0.01). High-density lipoprotein improved with the intervention arm from baseline to EOS (95% CI: -0.157 to -0.034; P < 0.05). CONCLUSIONS Although there was no significant difference in the prevalence of metabolic syndrome between study arms, we observed decreased blood glucose levels in the I-arm compared with the C-arm and improved high-density lipoprotein within the I-arm, following lifestyle modification and regular screening for CVD risk factors in WLHIV.

Pathophysiology and Clinical Management of Dyslipidemia in People Living with HIV: Sailing through Rough Seas. Life (Basel) 2024; 14:449. [PMID: 38672720 PMCID: PMC11051320 DOI: 10.3390/life14040449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 03/26/2024] [Accepted: 03/27/2024] [Indexed: 04/28/2024] Open
Abstract
Infections with human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) represent one of the greatest health burdens worldwide. The complex pathophysiological pathways that link highly active antiretroviral therapy (HAART) and HIV infection per se with dyslipidemia make the management of lipid disorders and the subsequent increase in cardiovascular risk essential for the treatment of people living with HIV (PLHIV). Amongst HAART regimens, darunavir and atazanavir, tenofovir disoproxil fumarate, nevirapine, rilpivirine, and especially integrase inhibitors have demonstrated the most favorable lipid profile, emerging as sustainable options in HAART substitution. To this day, statins remain the cornerstone pharmacotherapy for dyslipidemia in PLHIV, although important drug-drug interactions with different HAART agents should be taken into account upon treatment initiation. For those intolerant or not meeting therapeutic goals, the addition of ezetimibe, PCSK9, bempedoic acid, fibrates, or fish oils should also be considered. This review summarizes the current literature on the multifactorial etiology and intricate pathophysiology of hyperlipidemia in PLHIV, with an emphasis on the role of different HAART agents, while also providing valuable insights into potential switching strategies and therapeutic options.

Abstract
The advent of newer and better tolerated antiretroviral therapy has progressively shortened the life expectancy gap between people living with HIV (PWH) and the general population. However, in this aging cohort, cardiovascular disease is now a significant cause of morbidity and mortality despite advances in cardiac care. Therefore, it is critical to assess and treat all cardiovascular disease risk factors, including dyslipidemia, early and aggressively in PWH. Data are not as robust regarding the pathogenesis and management of dyslipidemia in PWH, with most evidence being extrapolated from the general uninfected population. In this review the authors describe the current understanding of the pathophysiology of HIV and antiretroviral therapy-induced dyslipidemia, and the approach to risk assessment and management, given that drug-drug interactions remain an important consideration in this population.

Abstract
HIV infection has transitioned from an acute, fatal disease to a chronic one managed by antiretroviral therapy. Thus, the aging population of people living with HIV (PLWH) continues to expand. HIV infection results in a dysregulated immune system, wherein CD4+ T cells are depleted, particularly in the gastrointestinal tract, disrupting the gut epithelial barrier. Long-term HIV infection is associated with chronic inflammation through potentially direct mechanisms caused by viral replication or exposure to viral proteins and indirect mechanisms resulting from increased translocation of microbial products from the intestine or exposure to antiretroviral therapy. Chronic inflammation (as marked by IL [interleukin]-6 and CRP [C-reactive protein]) in PLWH promotes endothelial cell dysfunction and atherosclerosis. PLWH show significantly increased rates of cardiovascular disease, such as myocardial infarction (risk ratio, 1.79 [95% CI, 1.54-2.08]) and stroke (risk ratio, 2.56 [95% CI, 1.43-4.61]). In addition, PLWH have increased levels of the coagulation biomarker D-dimer and have a two to ten-fold increased risk of venous thromboembolism compared with the general population. Several small clinical trials analyzed the effect of different antithrombotic agents on platelet activation, coagulation, inflammation, and immune cell activation. Although some markers for coagulation were reduced, most agents failed to reduce inflammatory markers in PLWH. More studies are needed to understand the underlying mechanisms driving inflammation in PLWH to create better therapies for lowering chronic inflammation in PLWH. Such therapies can potentially reduce atherosclerosis, cardiovascular disease, and thrombosis rates in PLWH and thus overall mortality in this population.
