Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

172
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis V

212
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pulmonary Tuberculosis I

277
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II

276
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis III

376
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Area of Science:

  • Public Health
  • Infectious Disease Control
  • Diagnostic Implementation

Background:

  • High-volume COVID-19 testing centers present an opportunity for integrated infectious disease screening.
  • Co-testing for tuberculosis (TB) alongside COVID-19 can streamline diagnostics in resource-limited settings.

Purpose of the Study:

  • To evaluate the operational feasibility of simultaneous COVID-19 and tuberculosis screening.
  • To assess the effectiveness of new workflows in tertiary hospital testing centers in Mumbai, India.

Main Methods:

  • Implemented rapid molecular testing platforms for both COVID-19 and TB at four centers.
  • Utilized verbal TB questionnaires and sputum sample analysis for TB screening.
  • Reversed workflow to screen TB patients for COVID-19 using rapid diagnostic tests.

Main Results:

  • Screened 14,588 presumptive COVID-19 patients for TB, identifying 3.3% with presumptive TB.
  • Confirmed 11.1% of tested presumptive TB cases as positive for TB (32 individuals).
  • Detected 2.5% of presumptive TB cases as COVID-19 positive via antigen tests and 0.7% via molecular testing.

Conclusions:

  • Simultaneous COVID-19 and TB screening is operationally feasible in India.
  • The integrated approach enhances real-time, on-site detection capabilities for both diseases.
