[Risk factors for early relapse of tuberculosis in Latvia]
Objective:
To evaluate risk factors for tuberculosis relapse within a short time after successful tuberculosis treatment among Latvian patients treated in 1996.
Design:
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).
Conclusion:
Alcohol use was the main risk factor for early tuberculosis relapse.

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
