Evaluation of the late presentation and associated factors of people living with HIV in Turkey. J Med Virol 2023; 95:e28781. [PMID: 37212337 DOI: 10.1002/jmv.28781] [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: 02/07/2023] [Revised: 03/31/2023] [Accepted: 04/28/2023] [Indexed: 05/23/2023]
Abstract
To identify the frequency of late presentation and late presentation with advanced disease, and associated factors in people living with HIV (PLHIV). Data from PLHIV diagnosed between 2008 and 2021 were retrospectively analyzed. Time of diagnosis (categorized based on key events affecting HIV care continuum e.g., national strategies, HIV guidelines, COVID-19 pandemic) and characteristics of late presenters (LP: CD4 ≤350 cells/mm³ or an AIDS defining event) and late presenters with advanced disease (LPAD: CD4 <200 cells/mm³) were describe. Associations between dependent (LP, LPAD) and independent variables were assessed using univariate/multivariate regression tests and presented as odds ratios (95% confidential interval). Of 1585 individuals (93.7% men), 42.5% were LPs and 19.3% were LPADs. Most common route of transmission was sex between men (54.3%). Non-LPs were younger (30 vs. 34 and 36 years; p < 0.001) and included more men who have sex with men (60.3% vs. 46.3% and 39.5%; p < 0.001). Factors associated with being LP and LPAD were age >30 years, heterosexual/unknown route of transmission (vs. sex between men), diagnosis in 2008-2013 or 2020-2021, (vs. 2014-2019). With reference to Turkish subjects, migrants from Africa had higher odds of being LPAD. LP is still an important health issue in HIV care. Heterosexuality, older age (>30 years), migration from Africa, and the COVID-19 pandemic are associated with delays in HIV presentation in Turkey. These factors need to be considered when developing and implementing policies to enable earlier diagnosis and treatment of PLHIV to achieve UNAIDS 95-95-95 targets.

[PMID: 30998710 PMCID: PMC6472762 DOI: 10.1371/journal.pone.0214800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Accepted: 03/20/2019] [Indexed: 11/18/2022] Open
Abstract
Background Prior to being spread throughout broader China, multiple human immunodeficiency virus (HIV)-1 genotypes were originally discovered in the Yunnan Province. As the HIV-1 epidemic continues its spread in Yunnan, knowledge of the influence of gender, age, and ethnicity to instances of HIV reservoirs will benefit monitoring the spread of HIV. Methods The degree to which T cells are depleted during an HIV infection depends on the levels of immune activation. T-cell subsets were assessed in newly-diagnosed HIV/AIDS patients in Yunnan, and the influence of age, gender, and ethnicity were investigated. Patients that were newly diagnosed with the HIV-infection between the years 2015 and 2018 at the First Affiliated Hospital of Kunming Medical College were selected for this study (N = 408). The lymphocyte levels and T cell subsets were retrospectively measured in whole blood samples by FACS analysis. Results The median CD4 count was 224 ± 191 cells/μl. Significantly higher mean frequencies and absolute numbers were observed in CD3+, CD3+CD4+, CD3+CD8+, CD45+, and CD3+CD4+/CD45+ in females compared to males. Han patients showed a higher total number of CD3+T cells and the ratio of CD3+ /CD45+ cells compared to any other ethnic minority (P < 0.001). The numbers of CD3+ T-cells, CD3+CD8+ T cells, and CD45+ T cells were highest in the age group ≥ 60. Significant differences were observed in the counts of CD3+, CD3+CD8+, and CD45+ cells and the ratio of CD3+/CD45+ and CD3+CD4+/CD45+ cells between the ≤ 29 and 30–59 age groups. Conclusion This study has revealed that low levels of CD4+ T cells can be observed in newly-diagnosed HIV/AIDS patients in the Yunnan province. It has also been demonstrated that gender, age, and ethnicity have a significant association with the ratio of T-cell subsets that may contribute to virus progression and disease prognosis in individuals belonging to certain subsets of the population. This study has highlighted the importance of HIV/AIDS screening in at-risk populations to ensure timely and adequate clinical management in Yunnan.
