We aimed to determine the frequency of latent TB infection in HD patients and to compare the effectiveness of the tests used. The files of 56 HD patients followed between 1 January 2021 and 1 October 2022 were retrospectively analyzed. Demographic data, the presence of the Bacillus Calmette-Guerin (BCG) vaccine, whether or not the patients had previously received treatment for TB before, the status of encountering a patient with active TB of patients over 18 years of age, without active tuberculosis and who had a T-SPOT.TB test or a Tuberculin Skin Test (TST) were obtained from the patient files. The presence of previous TB in a posterior\u2013anterior (PA) chest X-ray was obtained by evaluating PA chest X-rays taken routinely. Of the patients, 60.7% (n = 34) were male and their mean age was 60.18 \u00b1 14.85 years. The mean duration of dialysis was 6.43 \u00b1 6.03 years, and 76.8% (n = 43) had 2 BCG scars. The T-SPOT.TB test was positive in 32.1% (n = 18). Only 20 patients (35.7%) had a TST and all had negative results. While the mean age of those with positive T-SPOT.TB results was higher (p = 0.003), the time taken to enter HD was shorter (p = 0.029). T-SPOT.TB test positivity was higher in the group that had encountered active TB patients (p = 0.033). However, no significant difference was found between T-SPOT.TB results according to BCG vaccine, albumin, urea and lymphocyte levels. Although T-SPOT.TB test positivity was higher in patients with a previous TB finding in a PA chest X-ray, there was no statistically significant difference (p = 0.093). The applicability of the TST in the diagnosis of latent TB infection in HD patients is difficult and it is likely to give false-negative results. The T-SPOT.TB test is not affected by the BCG vaccine and immunosuppression. Therefore, using the T-SPOT.TB test would be a more appropriate and practical approach in the diagnosis of latent TB in HD patients.<\/jats:p>","DOI":"10.3390\/diagnostics13142369","type":"journal-article","created":{"date-parts":[[2023,7,14]],"date-time":"2023-07-14T08:35:47Z","timestamp":1689323747000},"page":"2369","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Diagnosis of Latent Tuberculosis Infection in Hemodialysis Patients: TST versus T-SPOT.TB"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3841-9109","authenticated-orcid":false,"given":"Umut Devrim","family":"Binay","sequence":"first","affiliation":[{"name":"Department of Infectious Diseases and Clinical Microbiology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, 24100 Erzincan, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali Veysel","family":"Kara","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, 24100 Erzincan, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faruk","family":"Karake\u00e7ili","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Clinical Microbiology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, 24100 Erzincan, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5347-7740","authenticated-orcid":false,"given":"Or\u00e7un","family":"Barkay","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Clinical Microbiology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, 24100 Erzincan, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,14]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2020).
