Tuberculosis is responsible for significant morbidity and mortality in the tropics. Active TB develops when host defences are impaired. Epidemiological evidence and studies addressing the double burden of communicable and non-communicable diseases demonstrate a clear association between diabetes and susceptibility to TB, treatment failure and complications. The immune mechanisms involved in host-pathogen interactions in co-morbid TB-diabetes are not well defined and require further investigation. This combined with the increase in diabetes predominately in low- and middle-income countries where TB is prevalent has major health implications.
