Abstract:
A review of the epidemiology of tuberculosis, its
contributing risk factors (excluding HIV) and the role of
screening latent tuberculosis infection in Malaysia was
done. Despite the global and domestic decrease in
prevalence rates of tuberculosis in the past decade, there is an alarming increase in the trend of non communicable
diseases in the country. High prevalence rates of major risk factors leading to reactivation of tuberculosis were seen within the population, with diabetes mellitus being in the forefront. The rising numbers in the ageing population of Malaysia poses a further threat of re-emergence of tuberculosis in the years to come. Economically, screening of diabetic patients with comorbidities for latent tuberculosis infection (LTBI) using two major techniques,
namely tuberculin sensitivity (TST) and Interferon gamma
release assay tests (IGRA) could be a viable option. The role of future research in the detection of LTBI in the Malaysian setting might be necessary to gauge the disease reservoir before implementing prophylactic measures for high risk groups involved.
