Current control measures focus on passive case finding and directly observed therapy, active case finding in selected population (e.g., close contact of index cases and prisoners), and diagnosis and treatment of latent tuberculosis infection in close contact. To maintain or even accelerate the decline of tuberculosis incidence, it is necessary to consider expanding the targeted approach to include other high risk populations. Despite the strong recommendation by WHO, currently diagnosis and preventive treatment of latent tuberculosis infection is not routinely implemented in people living with HIV/AIDS, dialysis patients, and kidney transplantation patients. In addition, it is unclear whether other risk groups (such as diabetes, smoking, alcohol use, and malnutrition) should be included in active case finding and/or screening for latent tuberculosis infection. These risk factors often have a moderate association (relative risk < 3) with active tuberculosis. Therefore the efficiency and cost-effectiveness of targeting these populations remain unclear. A risk stratification system to help identify the population with the highest risk is urgently needed.We propose to conduct a one-year integrated project to address the research and policy need for latent tuberculosis infection treatment and active case finding. We will conduct empirical study on people living with HIV/AIDS, dialysis patients, and kidney transplantation patients to assess the prevalence of latent tuberculosis infection using interferon gamma release assay. For those who are test positive for latent infection, we will provide prophylactic treatment using directly observed therapy (DOPT). For the populations with moderately elevated tuberculosis risk, we will use a nationally representative health survey (National Health Interview Survey) to construct a cohort to comprehensively assess the risk of tuberculosis among specific populations. The cohort profile will be used to construct and validate a risk scoring system for active tuberculosis. The scoring system can be used to identify the groups with the highest risk of tuberculosis (e.g., diabetes with poor control plus smoking plus malnutrition) as the target of case finding and latent infection treatment. Our integrated project will add to the existing tuberculosis control interventions and help formulate the post-2015 tuberculosis control policy.潛伏結核感染預防投藥主動個案發現愛滋病洗腎腎臟移植風險評分系統latent tuberculosis infectionpreventive treatmentactive case findingHIV/AIDSdialysiskidney transplantationrisk scoring systemStrengthening latent tuberculosis treatment and active case finding in high risk populations: empirical studies and development of risk prediction model
