title: [Risk factors for early relapse of tuberculosis in Latvia].
abstract: OBJECTIVE
  To evaluate risk factors for tuberculosis relapse within a short time after successful tuberculosis treatment among Latvian patients treated in 1996.
  
  
  METHODS
  Retrospective case-control study of tuberculosis patients diagnosed and treated successfully in 1996.
  
  
  RESULTS
  48 cases and 96 matched controls were included in the study. 18 cases and 22 controls had documentation of at least one interruption (OR 2.96; 95% CI 1.09-7.99). Early relapse was not associated with type of treatment facility, age or unemployment, but was positively associated with alcohol use (OR 17.70; 95% CI 4.14-75.77). In a multivariate analysis, only alcohol use was significantly associated with early relapse (OR 16.63; 95% CI 3.63-76.10).
  
  
  CONCLUSIONS
  Alcohol use was the main risk factor for early tuberculosis relapse.
