more » ... the association between diabetes mellitus and latent tuberculosis infection among a cohort of household contacts exposed to active tuberculosis in Ethiopia, focusing attention on the need for further translational research to determine the mechanisms of susceptibility to Mycobacterium tuberculosis infection among individuals with diabetes and pre-diabetes. OBJECTIVES/GOALS: Diabetes mellitus (DM) is an established risk factor for active TB disease, but there is limited understanding of the relationship of DM and latent tuberculosis (LTBI). We sought to determine the relationship between DM or pre-DM with LTBI among household or close contacts (HHCs) of active TB cases in Ethiopia. METHODS/STUDY POPULATION: We conducted a cross-sectional study of the HHCs of index active TB cases enrolled in an ongoing TB Research Unit (TBRU) study in Addis Ababa, Ethiopia. HHCs of individuals with laboratory-confirmed TB had QuantiFERON ®-TB Gold Plus (QFT) and glycated hemoglobin (HbA1c) tests performed. LTBI was defined as a positive QFT and lack of symptoms. HbA1C results were used to define no DM (HbA1c <5.7), pre-DM
