INTRODUCTION. Tuberculosis (TB) is a significant global health concern, particularly in developing countries. Diagnosing latent tuberculosis infection (LTBI) in hemodialysis patients is crucial because of the risk of developing active tuberculosis in this population due to attenuated immune response. Herein, we assessed the prevalence of LTBI in hemodialysis patients. METHODS. In this cross-sectional study, we included all patients referred to hemodialysis centers in Kohgiluyeh and Boyer-Ahmad Province, southwest Iran, in 2018 through census sampling. Tuberculin skin test (TST) was utilized to screen the patients for LTBI. All steps were done by trained physicians. RESULTS. In total, 183 patients (mean age: 59.3, SD= 16.0) were included in the study of which 76 (41.5%) were females, and 107 (58.5%) were males. Neither the patients nor their family members had a history of tuberculosis. Assuming an above 5-millimeter enduration as a positive TST result, 22 patients (12%) had LTBI. None of the demographic or clinical features differed between TST -negative and -positive groups. CONCLUSION. Hemodialysis patients are prone to LTBI due to several immunological and environmental factors. Screening for LTBI may be beneficial to prevent active tuberculosis in this population.
