title: Low prevalence of diabetes mellitus in patients with tuberculosis in Cotonou, Benin.
abstract: METHODS
  The three Basic Management Units (BMUs) of the National Tuberculosis Programme (NTP) in Cotonou, Benin.
  
  
  OBJECTIVE
  To determine the prevalence of diabetes mellitus (DM) among tuberculosis (TB) patients in Cotonou.
  
  
  METHODS
  A cross-sectional study of consecutively registered TB patients treated for a minimum of 2 weeks between June and July 2014 in the three BMUs, with measurement of their fasting blood glucose (FBG). A patient was considered as having DM if venous FBG was ⩾7 mmol/l or if they reported a known history of DM.
  
  
  RESULTS
  There were 159 patients assessed: 114 with new smear-positive pulmonary tuberculosis (PTB), 5 with new smear-negative PTB, 8 with extra-pulmonary TB, 21 retreatment patients with fully susceptible bacilli and 11 with multidrug-resistant TB. Of these, respectively 31 (19%), 18 (11%) and 10 (6%) were human immunodeficiency virus co-infected, smokers and hypertensive. Eight patients (5%) had impaired fasting glucose and three (1.9%) had DM (FBG ⩾ 7 mmol/l), of whom two were already known to have the disease and one was newly diagnosed.
  
  
  CONCLUSIONS
  DM may not be an important risk factor for TB in Cotonou. A larger study on TB and DM in the whole country is needed.
