Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

225
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 IV01:26

Pulmonary Tuberculosis IV

186
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 I

297
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

303
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:

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Area of Science:

  • Immunology
  • Infectious Diseases
  • Pharmacology

Background:

  • Tuberculosis (TB) remains a major global health threat, with conventional treatments challenged by drug resistance and side effects.
  • Current antitubercular drugs face diminishing efficacy against emerging drug-resistant Mycobacterium tuberculosis (Mtb).
  • There is an urgent need for novel therapeutic strategies to effectively manage TB.

Purpose of the Study:

  • To introduce host-directed therapy (HDT) as a promising alternative to conventional TB treatment.
  • To explore drug repositioning for HDT applications in TB management.
  • To review existing repositioned drugs for HDT and elucidate their mechanisms of action.

Main Methods:

  • Review of current literature on host immune responses to Mtb infection.
  • Analysis of Mtb immune-evasion mechanisms.
  • Examination of drug repositioning strategies for HDT.

Main Results:

  • HDT modulates host immune responses to control Mtb infection.
  • HDT aims to enhance host antimicrobial activity and reduce detrimental inflammation.
  • Several repositioned drugs show potential for use in HDT against TB.

Conclusions:

  • Host-directed therapy (HDT) presents a viable alternative strategy for treating tuberculosis.
  • Repositioned drugs offer a promising avenue for developing effective HDT regimens.
  • Further research into HDT mechanisms and drug efficacy is crucial for combating TB.
