Pulmonary tuberculosis with acute respiratory failure.

Area of Science:

• Pulmonology
• Infectious Diseases
• Critical Care Medicine

Background:

• Pulmonary tuberculosis (TB) can lead to acute respiratory failure (ARF), a severe complication.
• Understanding clinical characteristics and mortality predictors in TB with ARF is crucial for patient management.
• The role of adjunctive corticosteroids in treating TB with ARF remains unclear.

Purpose of the Study:

• To evaluate clinical features, prognoses, and mortality predictors in TB patients with ARF.
• To investigate the potential benefits of adjunctive corticosteroid therapy in this patient group.
• To identify factors associated with poor outcomes in tuberculous pneumonia (TBP) with ARF.

Main Methods:

• Retrospective analysis of 90 TB patients with ARF requiring mechanical ventilation (1989-2006).
• Patients categorized into tuberculous pneumonia (TBP) and miliary TB (MTB) groups.
• Multivariate analysis employed to identify predictors of mortality and survival.

Main Results:

• No significant difference in in-hospital mortality between TBP (68.2%) and MTB (58.3%) groups.
• Advanced age and non-septic shock were associated with poor outcomes in TBP patients.
• Corticosteroid use was a predictor of survival in TBP patients, though efficacy requires further study.

Conclusions:

• Advanced age and shock are significant predictors of mortality in TBP with ARF.
• Corticosteroids may offer survival benefits, but their definitive role requires confirmation.
• Randomized controlled trials are necessary to establish the efficacy of corticosteroids in TBP with ARF.
