Summary
Tuberculosis (TB) causes significant disabilities, with mental health and respiratory issues being most common. Further research is needed to quantify and address these TB-related disabilities globally.
Area of Science:
- Global Health
- Epidemiology
- Disability Studies
Background:
- Sustainable Development Goals target improved global health by 2030.
- Tuberculosis (TB) is a significant cause of disability, but its full extent is not well-quantified.
- Quantifying TB-related disabilities is crucial for public health interventions.
Purpose of the Study:
- To systematically review and quantify the prevalence and types of disabilities associated with tuberculosis (TB).
- To identify the most common TB-related disabilities and analyze their distribution across different country income levels.
- To investigate the association between drug-resistant TB and specific types of disabilities.
Main Methods:
- Systematic review of 131 studies involving 217,475 patients across 49 countries.
- Pooled prevalence of disabilities calculated using the inverse variance heterogeneity model.
- Mapping of common disability types by country income level and association with drug-resistant TB.
Main Results:
- Mental health disorders (23.1%), respiratory impairment (20.7%), and musculoskeletal impairment (17.1%) were the most prevalent TB-related disabilities.
- Respiratory impairment and mental health disorders were highest in low-income countries.
- Drug-resistant TB was linked to higher rates of respiratory, neurological, hearing impairments, and mental health disorders.
Conclusions:
- TB-related disabilities are frequently reported and diverse.
- There is an urgent need for standardized reporting tools for TB-related disability.
- Further research is essential to better quantify and mitigate the impact of TB-related disabilities.

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...

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 (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:

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...

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...
