Diabetes and pulmonary tuberculosis are the major public health problems in developing countries. The rising prevalence of Diabetes Mellitus in high TB burden countries may adversely affect TB control. Diabetes Mellitus (DM) almost triples the risk of developing tuberculosis (TB). A meta-analysis demonstrated that having diabetes was associated with an overall relative risk (RR) of 3.11 for contracting TB. However, neither international guidelines nor Indiaâs Revised National TB Control Programme (RNTCP) currently recommend active screening of TB patients for detection of DM.
The estimated prevalence of DM in India in 2010 was 51 million and this is projected to increase to 70 million by 2025. In India, 15% of pulmonary tuberculosis cases have been estimated to be attributable to DM. An analysis of nutrition and DM changes in India also suggests that increased DM prevalence between 1998 and 2008 contributed to an increase in the total number of TB cases in the country which exceeded the rate of population growth in the same time period.
