The intersection of Human Immunodeficiency Virus (HIV) infection and cardiovascular disease (CVD) represents a significant area of concern; advancements in antiretroviral therapy (ART) have notably extended the life expectancy of people living with HIV (PLWH), concurrently elevating the prevalence of chronic conditions such as CVD. This paper explores the multifaceted relationship between HIV infection, ART, and cardiovascular health, focusing on the mechanisms by which HIV and ART contribute to increased cardiovascular risk, including the promotion of endothelial dysfunction, inflammation, immune activation, and metabolic disturbances. We highlight the critical roles of HIV-associated proteins—Tat, Nef, and gp120—in accelerating atherosclerosis through direct and indirect pathways that exacerbate endothelial damage and inflammation. Additionally, we address the persistent challenge of chronic inflammation and immune activation in PLWH, factors that are strongly predictive of non-AIDS-related diseases, including CVD, even in the context of effective viral suppression. The impact of ART on cardiovascular risk is examined, with particular attention to the metabolic implications of specific ART regimens, which can influence lipid profiles and body composition, thereby modifying CVD risk. The therapeutic potential of statins, aspirin, and emerging treatments such as PCSK9 inhibitors in mitigating cardiovascular morbidity and mortality among PLWH is discussed, alongside considerations for their use in conjunction with ART. Our review underscores the necessity for a comprehensive, multidisciplinary approach to cardiovascular care in PLWH, which integrates vigilant cardiovascular risk assessment and management with HIV treatment. As we navigate the evolving landscape of HIV care, the goal remains to optimize treatment outcomes while minimizing cardiovascular risk, ensuring that the gains in longevity afforded by ART translate into improved overall health and quality of life for PLWH.

Background: Long-acting injectable antiretroviral therapy (LA-ART) with cabotegravir and rilpivirine (CAB + RPV) has emerged as a promising alternative to daily oral regimens for people living with HIV (PLWH), particularly those facing adherence challenges. While clinical trials have demonstrated its efficacy, real-world evidence remains limited. Methods: This retrospective, multicenter study evaluated the efficacy and safety of CAB + RPV in 160 virologically suppressed PLWH across eight Italian infectious disease units. Participants received intramuscular CAB (600 mg) and RPV (900 mg) every eight weeks without an oral lead-in phase. Clinical, immunological, and biochemical parameters were assessed at baseline and after 24 weeks. Results: At week 24, 96.25% of participants maintained virological suppression, and the proportion of individuals with target-not-detected viral load increased from 71% to 76%. Only one case of virological failure was observed. Significant immunological improvements included an increase in the CD4+/CD8+ ratio (p = 0.0038) and a reduction in CD8+ T-cell count (p = 0.0150). Biochemical analysis showed a decrease in serum creatinine (p < 0.0001) and an increase in HDL cholesterol (p = 0.0223). Treatment discontinuation occurred in 3.75% of participants, primarily due to adverse events or psychological factors. Conclusions: CAB + RPV demonstrated high efficacy and tolerability in a real-world setting, with favorable immunological and metabolic outcomes. These findings support its use as a viable therapeutic option for PLWH, especially those with adherence barriers. Further long-term studies are warranted to confirm these results across broader populations.

In 2022, 20 million women globally were living with HIV, yet they remain underrepresented in clinical trials, including those for antiretroviral treatments (ART). This study assesses the safety and efficacy of the long-acting cabotegravir-rilpivirine (CAB-RPV) regimen in a cohort of 54 women living with HIV (WLWH) over 24 weeks. A retrospective cohort study from the Sardinian HIV Network and Sicilian HIV Cohort (SHiNe-SHiC) included WLWH who switched to CAB-RPV. Primary objectives were achieving and maintaining HIV RNA levels <50 copies/mL at 24 weeks. Secondary objectives included treatment safety, durability, and reasons for discontinuation. Data on demographics, viro-immunological markers, lipid profiles, and treatment interruptions were analyzed. Of 54 WLWH, 46 reached 24 weeks. The median age was 50 years. A total of 71.8% transitioned from dolutegravir (DTG) regimens. Virological suppression was 97.8% at baseline and 95.5% at 24 weeks. Significant increases in the CD4/CD8 ratio (p = 0.0076) and decreases in serum creatinine levels (p = 0.0109) were observed. Cholesterol, triglycerides, ALT, and AST levels remained unchanged. The CAB-RPV regimen demonstrated significant virological and immunological efficacy and safety in women living with HIV over 24 weeks. Notably, the improvement in the CD4/CD8 ratio and the increase in the percentage of women achieving target not detected (TND) status highlight the regimen’s effectiveness. These findings emphasize the importance of gender-focused research in HIV treatment and the need for equitable access to effective treatment options for women, which is crucial for global efforts to eliminate HIV.
