Abstract
BACKGROUND HIV-1-associated neurocognitive disorders (HAND) in stable patients undergoing antiretroviral therapy (ART) may result from ongoing immune dysregulation and chronic inflammation. A contributing factor may result from the unstable HLA class I allele, HLA-C*07. OBJECTIVE To assess the genetic profile of killer-cell immunoglobulin-like receptors (KIR), human leukocyte antigens (HLA), and immune activation or senescence markers and their association with HAND in stable HIV-1 patients receiving ART. METHODS An observational cross-sectional study was carried out with 96 patients with asymptomatic or symptomatic HAND. HLA and KIR as well as immune activation/senescence biomarkers in peripheral blood cells were assessed by SSO-Luminex typing and flow cytometry, respectively. RESULTS HLA-C*07 is associated with symptomatic HAND. The frequency of two copies of HLA-C*07 was higher in patients with symptomatic than with asymptomatic HAND (12.0 vs. 2.2%, ρ < 0.001). The percentage of senescent CD8+CD28- T-cells was higher in patients with two copies of HLA-C*07 (ρ < 0.05). In patients with symptomatic HAND, the percentages of non-senescent CD8+CD28+ T cells were inversely proportional to the number of copies of the HLA-C*07 (ρ < 0.05). CONCLUSION Patients with symptomatic HAND showed a higher frequency of the homozygotic unstable HLA-C*07 allotype, which could be associated with neurocognitive complications. Two copies of HLA-C*07 were associated with immune senescent T lymphocyte profiles characterized by the loss of CD28 expression.

Medicine (Baltimore) 2022; 101:e29162. [PMID: 35421069 PMCID: PMC9276288 DOI: 10.1097/md.0000000000029162] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 03/06/2022] [Indexed: 01/04/2023] Open
Abstract
Combined antiretroviral therapy (cART) increased the life expectancy of people living with Human Immunodeficiency Virus (HIV) (PLHIV) and remarkably reduced the morbidity and mortality associated with HIV infection. Consequently, PLHIV are experiencing non-acquired immunodeficiency syndrome (AIDS) associated comorbid conditions including diabetes, hyperlipidemia, hypertension, and cardiovascular disease. The aim of this study is to determine the frequency of non-AIDS associated comorbid conditions among a cohort of PLHIV on cART in Lebanon.Data were collected between November 2018 and December 2019 from 105 voluntary participants. A standardized questionnaire was used to collect demographic and behavioral data including lifestyle, smoking, physical activity, substance use and abuse in addition to co-infections and family history of non-communicable diseases. Moreover, data on occurrence and treatment of cardiovascular disease, hypertension, diabetes, lipid and metabolic disorders as well as mental health were collected. Blood samples were used to assess the levels of fasting blood sugar (FBS), glycosylated hemoglobin (HbA1C), triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein, total cholesterol, and serum creatinine.Hypertension (29.5%) and hyperlipidemia (29.5%) followed by diabetes (23.7%) and cardiovascular disease (9.7%) were mainly reported among study participants. Higher rate of comorbid conditions was observed among participants >40 years of age than those ≤40 years with both hypertension and hyperlipidemia most commonly reported. Older age (odds ratio [OR] 7.6; 95% CI: 1.83-31.98; P = .005) is associated with higher odds of having hyperlipidemia. Moreover, participants on cART for ≥10 years are 5 times more likely to have hyperlipidemia (OR 5; 95% CI: 1.08-22.73; P = .039). Our results also showed that study participants did not experience anxiety, depression or somatic symptoms and that there was no association between these mental disorders and older age or comorbidities.Our results provide important information on HIV trends and associated comorbidities in Lebanon and can be used to improve the management of non-communicable diseases among PLHIV.

Abstract
To better deliver antiretroviral drugs for treating patients with acquired immune deficiency syndrome (AIDS) with poor immune reconstitution, a novel nanopole capsule was designed in this study. Forty-eight patients with AIDS with poor immune reconstitution were chosen as subjects to test their immune state. CD4+ T and Regulatory T cells (Treg) infected with HIV were cultured to test polyethyleneimine (PEI) and polychitosan (PC) drug delivery system efficiency. The infiltration efficiency test was performed to study the drug delivery efficiency of the delivery systems, and the cell numbers of CD4+ T and Treg cells infected with HIV were calculated to evaluate the therapeutic effect. The results showed that patients with AIDS with poor immune reconstitution had lower CD4+ T cell count and higher Treg cell count. Furthermore, the infiltration efficiency of the PC drug delivery system was higher than that of the PEI drug delivery system, and the therapy efficiency of antiretroviral drugs was greatly improved in the PC group. Additionally, the improvement of CD4+ T and Treg cells damaged by HIV was greater in the PC group. Sequentially, the PC system can better deliver and release loaded antiretroviral drugs and may be a better choice for treating patients with AIDS with poor immune reconstitution in the future.
