Risk factors for extra-pulmonary tuberculosis compared to pulmonary tuberculosis
1Division of Infectious Diseases, Department of Internal Medicine, E-Da Hospital/I-Shou University, Kaohsiung, Taiwan.
Summary
Identifying risk factors for extra-pulmonary tuberculosis (EPTB) compared to pulmonary tuberculosis (PTB) is crucial. Female sex, absence of diabetes, end-stage renal disease, and non-smoking were linked to EPTB.
Area of Science:
- Infectious Diseases
- Epidemiology
- Clinical Medicine
Background:
- Tuberculosis (TB) remains a significant global health challenge.
- Extra-pulmonary TB (EPTB) presents diverse symptoms, complicating diagnosis compared to pulmonary TB (PTB).
Purpose of the Study:
- To analyze risk factors associated with EPTB in comparison to PTB.
Main Methods:
- Retrospective study conducted at a university-affiliated hospital in southern Taiwan.
- Compared demographic data and underlying clinical conditions of EPTB and PTB patients.
- Utilized multivariate logistic regression to identify independent risk factors for EPTB.
Main Results:
- Out of 766 TB patients, 102 (13.3%) had EPTB and 664 (86.7%) had PTB.
- Bone and joint involvement was the most common EPTB site (24.5%).
- Independent risk factors for EPTB included female sex, absence of diabetes, presence of end-stage renal disease, and not smoking.
Conclusions:
- This study identifies key risk factors differentiating EPTB from PTB.
- Physicians should maintain a high index of suspicion for EPTB based on these identified risk factors to ensure timely and accurate diagnosis.

Pulmonary Tuberculosis III
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:
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary 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.

Pulmonary Tuberculosis II
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 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...

Tuberculosis
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...
Pulmonary Tuberculosis V
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...
