We identified reports of high prevalence and increased risk for sarcopenia due to factors such as prolonged exposure to antiretroviral drugs, lack of physical activity, central obesity, drug use, and other sociodemographic factors, as well as disease duration. HIV should be considered a risk factor for sarcopenia, and evaluation of sarcopenia should be included as part of the comprehensive medical care of PLHIV.

The challenge arises from an enormous diversity of HIV-1 strains and their rapid evolution ahead of effective immune responses. HIV-1 evasion from host immunity contributes to viral spread and pathogenesis, thus understanding the mechanisms of HIV-1 immune evasion is important. In this review, we summarized our present knowledge on the mechanisms how HIV-1 escapes immune responses.

The predictive value of HIV-related factors and traditional cardiovascular factors with PAH is inconsistent across studies. The objective is to determine the roles of HIV-related risk factors and traditional cardiovascular risk factors in the development of PAH in adults with HIV. We searched Pubmed/Medline, Embase, Web of Science, and Google Scholar to identify studies published between January 1, 2000 and February 23, 2021 on risk factors associated with PAH among people living with HIV (PLWH). Ten studies were included for final analysis. PLWH with PAH had higher mean age (weighted mean difference [WMD] = 2.27, 95% confidence interval [CI] 0.31 ~ 4.24), and lower mean CD4 cell count (WMD = -95.8, 95% CI -153.41 ~ -38.2). Meanwhile, they were more likely to have detectable viral load (odds ratio [OR] = 1.36, 95% CI 1.16 ~ 1.60), to accompany arterial hypertension (OR = 2.02, 95% CI 1.51 ~ 2.71) and less likely to receive antiretroviral therapy (ART) (OR = 0.84, 95% CI 0.72 ~ 0.99). Besides, more intravenous drug users were observed in HIV-infected adults with PAH (OR = 2.25, 95% CI 1.51 ~ 3.33). HIV infection itself and ART impact PAH in two opposite ways. Traditional cardiovascular factors such as arterial hypertension, and older age are also important to the development of PAH. Screening HIV-related factors and traditional cardiovascular factors may help to target and manage patients at risk.</p>","PeriodicalId":7685,"journal":{"name":"AIDS reviews","volume":"24 2","pages":"59-68"},"PeriodicalIF":2.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39694670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence suggests that the mechanisms of viral control in these individuals are heterogeneous. In this review, we highlight the viral and host factors, particularly host immunological and immunogenetic factors that are associated with controller status. Despite the broad heterogeneity within controllers, there is compelling evidence that cytotoxic CD8+ T lymphocyte responses act as the main driver of control in the majority of these individuals, especially in those with protective HLA-I alleles. Further investigation of controllers without protective HLA-I alleles is required as it seems that this subset exhibits more durable control of HIV-1 disease progression. Understanding the immune defense mechanisms in controllers provides hope for harnessing these responses in the general population, either for protective or therapeutic vaccines or to achieve a functional cure in infected individuals.</p>","PeriodicalId":7685,"journal":{"name":"AIDS reviews","volume":"24 2","pages":"51-58"},"PeriodicalIF":2.2,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39815820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
