Data are scarce regarding the prevalence of diabetes mellitus (DM) among tuberculosis (TB) patients in Bangladesh. This study was undertaken to estimate the number needed to screen (NNS) to identify a case of DM among those with TB symptoms and those with confirmed TB disease, and to identify factors predicting treatment outcomes of TB patients with and without DM. Persons attending public-private model screening centres in urban Dhaka for the evaluation of TB were offered free blood glucose

Among 7647 people evaluated for both TB and DM, the NNS was 35 (95% confidence interval (CI) 31-40) to diagnose one new case of DM; among those diagnosed with TB, the NNS was 21 (95% CI 17-29). Among those with diagnosed TB, patients with DM were more likely to have cavitation on chest X-ray compared to those without DM (31% vs 22%). Treatment failure (odds ratio (OR) 18.9, 95% CI 5.43-65.9) and death (OR 2.08, 95% CI 1.11-3.90) were more common among TB patients with DM than among TB patients without DM. DM was the most important predictor of a poor treatment outcome in the classification analysis for TB patients aged 39 years and above. A considerable burden of DM was found among patients accessing TB diagnostics through a public-private model in urban Bangladesh, and DM was associated with advanced TB disease and a high rate of poor treatment outcome.
