[Composition and morphological characteristics of deaths from tuberculosis]

Area of Science:

• Pulmonary Medicine
• Pathology
• Epidemiology

Context:

• Analysis of 248 adult deaths from pulmonary tuberculosis.
• Evaluation of causes of mortality and disease progression patterns.
• Assessment of trends in intrathoracic lymph node lesions and dissemination.

Purpose:

• To identify the primary causes of death in adult pulmonary tuberculosis.
• To analyze the changing patterns of tuberculosis dissemination and lymph node involvement.
• To determine factors contributing to progressive tuberculosis and mortality.

Summary:

• Progressive tuberculosis, primarily caseous pneumonia (60.9%), was the leading cause of death.
• Multicavernous processes with bronchogenic (28%) and hematogenic (15%) dissemination were less frequent causes.
• Significant increases in intrathoracic lymph node lesions (10.8% to 30.4%) and hematogenic dissemination (6.7% to 25.6%) were observed between 1994-1999.
• Patient non-compliance, delayed medical visits, lack of fluorography, and treatment errors were key factors favoring progressive disease.

Impact:

• Highlights the critical role of patient adherence in managing tuberculosis.
• Indicates a concerning rise in specific intrathoracic lymph node involvement and hematogenic spread.
• Informs public health strategies for improving tuberculosis outcomes through enhanced patient education and compliance measures.
