    OBJECTIVE: Latent tuberculosis infection (LTBI) screening is strongly recommended in the pre -transplant evaluation of solid organ transplant (SOT) recipients, although it remains inadequate in many transplant centers. We decided to investigate pre -transplant TB risk assessment, LTBI treatment, and registry rates in T & uuml;rkiye. MATERIAL AND METHODS: Adult SOT recipients who underwent tuberculin skin test (TST) and/or interferon -gamma release test (IGRA) from 14 centers between 2015 and 2019 were included in the study. An induration of >= 5 mm on TST and/or probable/positive IGRA (QuantiFERON-TB) was considered positive for LTBI. Demographic features, LTBI screening and treatment, and pre -/post -transplant TB history were recorded from the electronic database of transplantation units across the country and pooled at a single center for a unified database. RESULTS: TST and/or IGRA were performed in 766 (33.8%) of 2266 screened patients most of whom were kidney transplant recipients (n = 485, 63.4%). LTBI screening test was positive in 359 (46.9%) patients, and isoniazid was given to 203 (56.5%) patients. Of the patients treated for LTBI, 112 (55.2%) were registered in the national registry, and 82 (73.2%) completed the treatment. Tuberculosis developed in 6 (1.06%) of 563 patients who were not offered LTBI treatment. CONCLUSION: We determined that overall, only one-third of SOT recipients in our country were evaluated in terms of TB risk, only 1 of the 2 SOT recipients with LTBI received treatment, and half were registered. Therefore, we want to emphasize the critical importance of pretransplant TB risk stratification and registration, guided by revised national guidelines.
