Current concepts in the management of tuberculosis

Area of Science:

• Public Health
• Infectious Diseases
• Global Health

Background:

• Tuberculosis (TB) remains a significant global health challenge, disproportionately affecting low-income nations.
• Individuals in close contact with active pulmonary TB patients and those from endemic areas are at high risk for primary infection.
• Patients with compromised immune systems face a heightened risk of latent TB infection (LTBI) reactivation.

Purpose of the Study:

• To summarize the diagnosis and management of tuberculosis (TB) and latent TB infection (LTBI).
• To highlight public health strategies for TB prevention and control.

Main Methods:

• Diagnosis of LTBI relies on tuberculin skin tests or interferon-γ release assays without active TB.
• Active TB diagnosis involves a combination of clinical, radiographic, microbiological, and histopathologic features.
• Recommended diagnostic methods for active pulmonary TB include sputum smears, culture, and nucleic acid amplification testing.

Main Results:

• Preferred treatment for LTBI is 9 months of isoniazid.
• Active TB requires multi-agent treatment to ensure bacterial clearance, reduce transmission, and prevent drug resistance.
• Directly observed therapy (DOT) is recommended for active TB treatment.

Conclusions:

• Effective TB management necessitates collaboration between healthcare professionals and public health departments.
• Specialized care is crucial for drug-resistant TB and HIV coinfection.
• Public health interventions like respiratory isolation, contact investigation, and reducing LTBI burden are vital for TB control.
