Let’s delve into the world of Tuberculosis with insights from Dr. Parthiv Shah, a renowned TB specialist in Mumbai. Tuberculosis (TB) is caused by Mycobacterium tuberculosis, a bacterium that can affect any part of the body. Understanding the distinction between latent TB infection (LTBI) and TB disease is crucial, as untreated TB disease can be fatal.

Latent Tuberculosis Infection (LTBI)

Latent Tuberculosis Infection (LTBI) is characterized by the presence of TB bacteria in the body, albeit in an inactive state. Individuals with LTBI typically do not exhibit any symptoms and are unable to transmit TB to others. Diagnosis of LTBI is usually confirmed through a positive TB skin or blood test.

TB Disease

  • Definition: Active growth of TB bacteria, often in the lungs.
  • Symptoms: Cough, chest pain, weight loss, fever, night sweats.
  • Transmission: Contagious, requiring prompt treatment.

Diagnostic Tests for TB

Dr. Parthiv Shah offers a range of diagnostic tests for TB, including TB skin tests, smear tests, culture tests, and drug sensitivity testing.

TB Skin Test

  • Purpose: To detect TB infection.
  • Procedure: Injection of tuberculin under the skin.
  • Interpretation: Positive reaction indicates TB infection.

Smear and Culture Tests

  • Smear Test: Detects TB bacteria in sputum within a day.
  • Culture Test: Identifies TB bacteria in sputum or body fluids in 4-6 weeks.

Drug Sensitivity Testing

  • Importance: Determines effective drugs for TB treatment.
  • Crucial for: Managing drug-resistant TB cases.

Treatment for TB Disease

The treatment approach for TB disease varies based on severity and drug sensitivity.

Drug-Sensitive TB (DSTB)

  • Regimen: 2HRZE/4HRE for H & R sensitive TB cases.
  • Phases: Intensive phase (IP) and continuation phase (CP).
  • Duration: Tailored based on TB type and patient response.

Drug-Resistant TB (DR TB)

  • Regimens: All-oral H mono/poly DR TB regimen, shorter MDR TB regimen.
  • Expertise: Dr. Parthiv Shah specializes in managing complex TB cases.
