title: Screening patients with tuberculosis for diabetes mellitus in Gujarat, India.
abstract: METHODS
  Anklav Tuberculosis Unit, Anand, Gujarat, India.
  
  
  OBJECTIVE
  To determine in a cohort of TB patients 1) the prevalence of diabetes (DM) and impaired fasting glucose (IFG), 2) the time taken for diagnosis, 3) demographic and clinical factors associated with DM and IFG, and 4) the number needed to screen (NNS) for diagnosing new cases of DM and IFG.
  
  
  METHODS
  Descriptive study. TB patients registered between January and September 2012 were asked whether they had a history of DM. Those with unknown DM were tested for random and fasting blood glucose (FBG). FBG of ≥126 mg/dl and 110-125 mg/dl were considered indicative of DM and IFG, respectively.
  
  
  RESULTS
  Of 556 TB patients, 553 (99%) were assessed: 36 (6.5%) had diabetes (14 had been previously diagnosed DM and 22 were newly diagnosed), and 39 (7%) had IFG. The median (interquartile range) time to DM diagnosis was 5 (1-17) days. Age ≥35 years was associated with DM. The NNS was 25 and 14 for one new case of DM and IFG, respectively, with a lower NNS in males, those aged ≥35 years, those with smear-positive pulmonary TB, retreatment patients and smokers.
  
  
  CONCLUSIONS
  This pilot project shows that it is feasible and valuable to screen patients with TB for DM in a routine setting, resulting in earlier identification of DM and opportunities for better management of comorbidity.
