Tuberculosis (TB) Diagnosis and Treatment

Tuberculosis (TB) is a serious infectious disease primarily affecting the lungs, though it can involve other parts of the body. Early diagnosis and proper treatment are crucial in controlling TB and preventing its spread.

Diagnosis

1. Medical History and Physical Examination:

  • Symptoms: Persistent cough, fever, night sweats, and weight loss.
  • Exposure History: Recent exposure to TB patients.

2. Tests:

  • Tuberculin Skin Test (TST): Also known as the Mantoux test, this intradermal injection of purified protein derivative (PPD) indicates exposure to TB but not necessarily active TB.
  • Interferon Gamma Release Assays (IGRAs): Blood tests detecting immune response to specific TB proteins; useful for those with the BCG vaccine or who cannot undergo TST.
  • Chest X-ray: Identifies lung abnormalities typical of TB.
  • Sputum Smear Microscopy: Examines sputum under a microscope for TB bacteria.
  • Sputum Culture: Cultures sputum samples to identify TB bacteria; the gold standard but takes several weeks.
  • Molecular Tests: Rapid tests like GeneXpert MTB/RIF detect TB and rifampicin resistance.

Treatment

1. Drug Regimens:

  • First-line Drugs: Standard treatment for active TB involves a 6-9 month combination of antibiotics:
    • Isoniazid (INH)
    • Rifampicin (RIF)
    • Ethambutol (EMB)
    • Pyrazinamide (PZA)
  • Directly Observed Therapy (DOT): Treatment may be administered under supervision to ensure adherence.

2. Drug-Resistant TB:

  • Multi-Drug Resistant TB (MDR-TB): Resistant to isoniazid and rifampicin; treated with second-line drugs for up to 24 months.
  • Extensively Drug-Resistant TB (XDR-TB): Resistant to isoniazid, rifampicin, one fluoroquinolone, and one injectable second-line drug; requires specialized care.

3. Latent TB Infection (LTBI):

  • Preventive Treatment: For individuals with a positive TB test but no symptoms, usually involves 3-9 months of isoniazid or a shorter course with rifapentine and isoniazid.

Follow-Up

Regular follow-up visits are necessary to monitor treatment progress, manage side effects, and ensure adherence. Monitoring may include repeat sputum tests and chest X-rays.

Prevention

  • Vaccination: The BCG vaccine provides some protection against TB, especially in children.
  • Infection Control: Good ventilation, wearing masks, and avoiding close contact with infectious individuals are crucial.

Early diagnosis and proper treatment are essential for controlling TB and preventing its spread.
