About
This is a prospective, multicenter observational cohort study aimed at establishing a nationwide post-TB lung disease registry in Korea. The study will enroll adult participants either undergoing treatment for pulmonary tuberculosis or with a history of treated TB. Over a five-year follow-up period, the study will assess the long-term health consequences of TB, focusing on respiratory symptoms, radiological changes, pulmonary function, and quality of life.
Full description
"The LIFE-TB (Long-Term Impacts on Lung Health and Life After Tuberculosis in Korea) study is a nationwide, prospective, multicenter observational cohort designed to systematically investigate the long-term impacts of tuberculosis (TB) on lung health and quality of life. This registry aims to fill the critical evidence gap in understanding post-TB lung disease (PTLD) by enrolling adults with a current diagnosis of pulmonary TB or a history of TB treatment.
Participants will be recruited from six tertiary care centers across Korea. Eligible individuals include those aged 19 or older who are either undergoing anti-TB treatment or have completed it. Exclusion criteria include extrapulmonary TB without lung involvement, age under 19, or refusal to consent.
Data will be collected at baseline and regularly over a five-year follow-up period. Clinical variables include demographic information (age, sex, BMI, smoking status), TB-related history (sputum smear/culture, drug resistance, treatment outcomes), comorbidities, and current medications. Clinical assessments involve standardized symptom scores (mMRC), chest imaging (X-ray and CT), spirometry, and validated instruments to assess quality of life (EQ-5D-5L, PROMIS, SGRQ). Laboratory data include blood tests (HbA1c, lipids), HIV/HBV/HCV status, and urine and ECG assessments at baseline.
Participants will be followed annually, with interim assessments including imaging, spirometry, and symptom scoring at specified intervals. No study-specific interventions or additional imaging are required beyond routine care. Chest CTs will only be collected if obtained for clinical purposes.
The study's primary objectives are to describe the prevalence and trajectory of PTLD-related abnormalities and identify factors associated with poor outcomes. Secondary analyses include trends in pulmonary function and quality of life over time, as well as health utilization patterns. Statistical analyses include descriptive statistics and multivariable logistic regression to identify risk factors.
All data will be anonymized and securely stored, following institutional and ethical guidelines. The study will contribute essential real-world data to inform national and international post-TB management strategies."
