Overview
Tuberculosis (TB) primarily affects the respiratory system, causing pulmonary infection characterized by chronic cough, fever, night sweats, and weight loss 3.Diagnosis
Clinical Symptoms: Chronic cough, fever, night sweats, weight loss 3.
Chest Imaging: Chest X-ray showing upper lobe infiltrates, cavitation, or pleural effusion 3.
Sputum Examination: Acid-fast bacilli (AFB) smear and culture; nucleic acid amplification tests (NAAT) for rapid diagnosis 3.
Tuberculin Skin Test (TST) or Interferon-Gamma Release Assays (IGRAs): To assess latent TB infection 3.Management
First-Line Drugs: Isoniazid (INH), Rifampin (RIF), Ethambutol (EMB), Pyrazinamide (PZA) 3.
Standard Regimen: 6 months total: 2 months of INH, RIF, EMB, PZA followed by 4 months of INH, RIF 3.
Adjunctive Treatments: Steroids for severe forms like tuberculous meningitis; surgical intervention for drug-resistant TB or complications like empyema 3.Special Populations
Pregnancy: Management similar to non-pregnant adults; INH is generally considered safe during pregnancy 3.
Pediatrics: Dosage adjusted by weight; close monitoring for side effects and adherence 3.
Elderly: Increased vigilance for drug interactions and comorbidities; dose adjustments may be necessary 3.
Comorbidities: Tailored treatment plans considering interactions with existing medications; close monitoring essential 3.Key Recommendations
Use standardized diagnostic approaches including imaging and microbiological testing for accurate TB diagnosis (Evidence: Strong 3).
Initiate treatment with a combination of first-line anti-tuberculous drugs tailored to the patient's condition (Evidence: Strong 3).
Monitor and adjust treatment in special populations such as pregnant women, children, and elderly patients due to unique physiological considerations (Evidence: Moderate 3).References
