Pulmonary Infections with Nontuberculous Mycobacteria, Catalonia, Spain, 1994-2014
Emerging Infectious Diseases
|May 19, 2018
Summary
Pulmonary nontuberculous mycobacteria infections in Spain increased over 21 years, particularly in males. Mycobacterium avium complex and M. abscessus rose, while M. kansasii declined.
Area of Science:
- Pulmonary Medicine
- Infectious Diseases
- Microbiology
Background:
- Nontuberculous mycobacteria (NTM) pulmonary infections lack mandatory systematic reporting in Spain.
- Understanding trends in NTM infections is crucial for public health.
- Retrospective analysis enables the study of long-term epidemiological patterns.
Observation:
- Data from Catalonia, Spain, covering January 1994 to December 2014 (21 years).
- Cases of pulmonary NTM infections were identified and analyzed retrospectively.
- Prevalence trends and demographic associations were examined.
Findings:
- Overall prevalence of pulmonary NTM infections significantly increased over the 21-year study period.
- Increased prevalence was statistically associated with the male sex.
- Specific mycobacterial species showed divergent trends: Mycobacterium avium complex and Mycobacterium abscessus prevalence rose, whereas Mycobacterium kansasii prevalence decreased.
Implications:
- The findings highlight a growing burden of NTM lung disease in Spain.
- Male sex is identified as a risk factor, warranting targeted awareness.
- Shifting species prevalence necessitates adaptive diagnostic and treatment strategies for NTM infections.

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...

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...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

01:19Overview of Pulmonary Circulation
3.3K
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...

01:19Factors Affecting Pulmonary Ventilation
3.2K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
