Factors that may contribute to increased weight gain include specific ART regimens (those initiating dolutegravir and tenofovir alafenamide or withdrawing tenofovir disoproxil and efavirenz), women with HIV, and certain virologic factors including lower baseline CD4 count and higher HIV viral load. Weight reduction starting at 5% body weight confers metabolic protection, such as improved hypertension and dysglycemia. Even greater metabolic impact has been shown with weight reduction in the approximate range of 15% body weight, as evidenced by decreases in cardiovascular disease mortality. Effective weight management is essential to reducing cardiometabolic risk, may not be achieved with lifestyle changes alone, and requires other therapeutic strategies. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are well recognized to provide potent weight reduction among persons with overweight/obesity; in addition, studies have shown cardiovascular benefit among those with established cardiovascular disease. Recent studies have permitted us to begin to understand the potential role of GLP-1 RAs among PWH and overweight/obesity. This review highlights weight gain specific to PWH and discusses current evidence and key clinical considerations for GLP-1 RA use among PWH.</p>","PeriodicalId":38738,"journal":{"name":"Topics in antiviral medicine","volume":"32 5","pages":"579-588"},"PeriodicalIF":0.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11737811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronically treated HIV disease is associated with ongoing systemic inflammation that contributes to the development of chronic conditions (eg, cardiovascular disease) and geriatric syndromes (eg, frailty). Apart from HIV disease, a progressive increase in systemic inflammation is a characteristic feature of biologic aging, a process described as \"inflammaging.\" Inflamm-aging is driven by persistent antigen stimulation and stress, leading to an immune profile characterized by elevated levels of blood inflammatory markers and cellular activation and senescence. Chronic HIV disease is hypothesized to accentuate the immune profile of inflamm-aging, in part through viral persistence in lymphatic tissues, permanent injury impairing immune recovery, the presence of copathogens, gut dysbiosis and microbial translocation, and chromosomal and genetic alterations associated with immune activation. Few strategies exist for safe and effective modulation of systemic inflammation among older PWH. The strongest current evidence supports aggressive management of modifiable risk factors such as lipids, blood pressure, and levels of physical activity. Future inflamm-aging research should be directed toward advancing the implementation of proven approaches, such as physical activity, as well as studying novel mechanisms of, and treatments for, inflamm-aging among PWH.</p>","PeriodicalId":38738,"journal":{"name":"Topics in antiviral medicine","volume":"32 5","pages":"589-596"},"PeriodicalIF":0.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11737810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data on treatment with long-acting injectable (LAI) antiretroviral therapy (ART) demonstrated high acceptability, retention, and virologic suppression including in groups that were not well represented in clinical trials including persons born female and persons with detectable viral loads. The adjuvanted hepatitis B vaccine appeared to be safe and appeared to be superior to conventional hepatitis B vaccines in persons with HIV (PWH) who were prior nonresponders to the hepatitis B vaccine. New therapies are in the pipeline for LAI hepatitis C medication that may cure hepatitis C with 1 injection. ACTG (AIDS Clinical Trials Group) A5359 showed that long-acting cabotegravir/rilpivirine (LA CAB/RPV) can be used effectively in PWH experiencing adherence challenges to oral ART and suggested a paradigm for treating this population with an unmet medical need.

The conference maintained its existing format and used a combination of plenary lectures, workshops, oral abstract sessions, themed discussions, and interactive symposia to deliver the latest advances in HIV/AIDS research to the almost 4000 delegates in attendance. As with previous CROI meetings, the conference provided a fertile environment for early-stage investigators who were interested in getting updates in areas of research outside of their particular domain. This was exemplified by the Scott M. Hammer Workshop for New Investigators and Trainees. Here, leading investigators helped orient new investigators and trainees to the various scientific presentations in the different thematic areas being covered at CROI. The meeting organizers did a great job of minimizing conflicts and made sure that talks in similar thematic areas would not end up in parallel sessions. The conference continues to focus on research related to HIV/AIDS and comorbidities. Approximately 20% of the accepted abstracts featured research on SARS-CoV-2 and 3% on mpox.

HIV testing, the gateway to prevention and to treatment, has not fully rebounded from the substantial declines seen during the early COVID-19 pandemic in some settings, although innovative strategies including home testing and opt-out testing in clinical settings appear to be reaching populations in need of testing. Several investigators reported on the efficacy and effectiveness of doxycycline used as postexposure prophylaxis (doxy-PEP) to prevent bacterial sexual transmitted infections in MSM and transgender women in clinical trials and clinic settings; citywide rates of chlamydia and syphilis have decreased in San Francisco after the rollout of the first doxy-PEP guidelines in the US. Lack of doxy-PEP efficacy in cisgender women in Kenya appears due to low adherence in that trial. Rollout and persistence on oral HIV preexposure prophylaxis (PrEP) are associated with reduced seroincidence on a population and individual level. The rollout of long-acting injectable cabotegravir (CAB-LA) PrEP is proceeding slowly in the US. New, longer-acting oral and injectable agents are in development, with preclinical and early clinical trial data presented at CROI. Oral PrEP uptake among populations in sub-Saharan Africa remains low in most settings, suggesting the need for more options and more support; point-of-care tenofovir testing appear acceptable in various populations and may improve adherence and identify PrEP users needing more support. Choice of PrEP or PEP including CAB-LA combined with clinical support substantially increased biomedical prevention coverage in East Africa. Novel approaches to PrEP rollout, including delivery using mobile services and in nonclinical settings appear to show promise.
