Data were collected through on-site questionnaire surveys and review of patient disease management records. QuantiFERON-TB Gold In-Tube (QFT) was used to detect LTBI. Multivariate logistic regression analysis was performed to identify factors associated with LTBI among PLWHA.

Additionally, the CD4\/CD8 ratio, in conjunction with QFT findings, could serve as a supplementary reference for LTBI risk assessment. These observations support a more tailored approach to LTBI screening in PLWHA, though their implementation should be validated in prospective studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fcimb.2025.1738028","type":"journal-article","created":{"date-parts":[[2026,1,19]],"date-time":"2026-01-19T06:31:55Z","timestamp":1768804315000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of factors influencing latent tuberculosis infection screening using QuantiFERON-TB Gold In-Tube in people living with HIV\/AIDS"],"prefix":"10.3389","volume":"15","author":[{"given":"Yiming","family":"Xu","sequence":"first","affiliation":[{"name":"School of Public Health, Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jincheng","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, Yangzhou Center for Disease Control and Prevention","place":["Yangzhou, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Song","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuying","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huan","family":"Ding","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shipeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiya","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuping","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Public Health, Nanjing Medical University","place":["Nanjing, China"]},{"name":"Department of Chronic Infectious Disease Control and Prevention, The Affiliated Wuxi Center for Disease Control and Prevention of Nanjing Medical University, Wuxi Center for Disease Control and Prevention","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,19]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1097\/CM9.0000000000003383","article-title":"Chinese guidelines for the diagnosis and treatment of human immunodeficiency virus infection\/acquired immunodeficiency syndrome (2024 edition)","volume":"137","year":"2024","journal-title":"Chin.
