title: Relationship between self reporting of past history of anti-tuberculosis treatment and radiographic findings in multidrug-resistant tuberculosis.
abstract: METHODS
  A referral hospital for multidrug-resistant tuberculosis (MDR-TB) patients in KwaZulu-Natal, South Africa.
  
  
  OBJECTIVE
  To investigate how self-reporting of past exposure to anti-tuberculosis therapy in MDR-TB patients relates to their chest radiographs.
  
  
  RESULTS
  Chest radiographs of 406 patients with bacteriologically confirmed MDR-TB who were admitted to a tertiary referral hospital during 1998-2001 were reviewed. Of 245 patients with chronic radiographic changes, 91% reported previous anti-tuberculosis treatment, while of 161 patients with acute radiographic changes, 70% reported no previous history of TB treatment.
  
  
  CONCLUSIONS
  Self-reporting by patients of previous anti-tuberculosis treatment relates to the duration of disease assessed radiologically, and is much more reliable than previously postulated.
