Study of Tests to Detect Latent and Subclinical Tuberculosis in Adults with End-Stage Kidney Disease and Kidney Transplants in Thailand

What this Trial Is About

Researchers are conducting an observational study involving about 160 patients with end-stage renal disease ESRD who are on renal replacement therapy or have received a living donor or deceased donor kidney transplant. The study focuses on detecting latent and subclinical tuberculosis TB in these patients by evaluating interferon-gamma release assays IGRA, symptom development, sputum Xpert MTBRIF assay, and chest radiographs. This research aims to understand the proportion of positive IGRA results associated with TB symptoms and diagnostic tests in this high-risk group. Participants include adults aged 18 years or older who have ESRD and are either undergoing hemodialysis or peritoneal dialysis or have undergone kidney transplantation. There are no treatment interventions as this is an observational study. Researchers will monitor participants over a two-year follow-up period to identify latent TB infection and active TB cases using IGRA tests, symptom screening, sputum tests, and chest X-rays. During the study, participants will undergo scheduled assessments including IGRA testing, symptom evaluation, sputum Xpert MTBRIF assay, and chest radiographs to detect TB infection. The main outcomes measured are the number of participants with positive IGRA tests and those diagnosed with latent or active TB during the two-year follow-up. No experimental treatments are given, and participants will continue their usual medical care throughout the study period.
