Abstract

The prevalence of non-communicable diseases is increasing worldwide, which coincides with the persistence of infectious diseases including tuberculosis. These can synergistically affect individual and population health. Three non-communicable diseases that are relevant because of their associated morbidity, mortality and disability are type 2 diabetes mellitus, chronic kidney disease and rheumatoid arthritis. There is some evidence that patients with these conditions are at increased risk of acquiring latent tuberculosis infection (LTBI) and of this progressing to active disease. Unfortunately, evidence on accurate testing and effective prophylactic treatment in these populations is lacking. This review discusses current evidence and recommendations for management of LTBI in these patients.
