Targeting of individuals for treatment of latent tuberculosis infection – a registerbased prospective cohort study - project description
Targeted testing and treatment of latent tuberculosis infection (LTBI) are important components of the World Health Organization’s (WHO’s) End TB strategy in low-incidence countries. The risk of developing TB after infection differs between individuals. To avoid treatment of a high number of infected persons to prevent one TB case, and to reduce the risk of severe adverse effects, treatment of LTBI is targeted primarily to individuals at highest risk of progression to TB. The use of preventive treatment for LTBI has increased in Norway. However, we have limited knowledge about medical risk factors, whether treatment is targeted to those at highest risk and to what extent this has an impact on the incidence of TB . The objective of this study is to explore the prevalence of risk factors among persons screened for LTBI or who have been notified to MSIS (TB register), and assess the impact of these factors in a Norwegian context.
The study includes blood-test results from eight Norwegian laboratories linked with data from Statistics Norway (SSB), the Norwegian Surveillance System for Infectious Diseases (MSIS), The Patient Registry (NPR) and the Norwegian Prescription Database (NorPD).
