Immunological studies on pulmonary tuberculosis: a preliminary report
Indian Journal of Medical Sciences
|October 1, 1989
Summary
This study found that tuberculosis patients have an inverse relationship between cell-mediated and humoral immunity, with T-cell defects more pronounced in Mantoux-negative individuals. Boosting T-cell responses may improve tuberculosis treatment outcomes.
Area of Science:
- Immunology
- Infectious Diseases
- Pulmonary Medicine
Background:
- Primary pulmonary tuberculosis affects cell-mediated and humoral immune responses.
- Evaluating immune status is crucial for understanding tuberculosis pathogenesis.
Purpose of the Study:
- To assess the immunological status of tuberculosis patients.
- To investigate cell-mediated (E-rosette) and humoral (EAC-rosette, immunoglobulins) immunity in tuberculosis.
- To correlate immune responses with Mantoux test results.
Main Methods:
- Immunological analysis of 71 tuberculosis patients and 41 controls.
- Evaluation of E-rosette, EAC-rosette assays, and serum immunoglobulin levels (IgG, IgA, IgM).
- Serum protein fractionation to analyze albumin and globulin levels.
Main Results:
- An inverse relationship observed between cell-mediated and humoral immune responses in tuberculosis patients.
- Pronounced defects in cell-mediated immunity noted in Mantoux-negative cases.
- Significant decrease in albumin and increase in globulin (especially gamma-globulin) levels.
Conclusions:
- Tuberculosis is associated with distinct alterations in immune responses.
- Therapeutic strategies should aim to enhance T-cell mediated immunity and modulate B-cell activity.
- Immune system modulation holds potential for altering tuberculosis disease progression.

01:29Pulmonary Tuberculosis I
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.

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...

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:

01:26Pulmonary Tuberculosis IV
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...

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 progression...

01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
