Summary
Swine flu (H1N1) can cause pulmonary fibrosis. This study found that residual lung scarring from swine flu pneumonia did not worsen over time in two patients, suggesting it is not a progressive condition.
Area of Science:
- Pulmonology
- Infectious Diseases
- Pathology
Background:
- The 2009 swine flu (H1N1) pandemic caused widespread bilateral pneumonia.
- While most patients recovered, some developed pulmonary fibrosis as a sequela.
- The long-term prognosis of post-swine flu pulmonary fibrosis remained uncertain.
Purpose of the Study:
- To report on the long-term progression of pulmonary fibrosis in patients who experienced swine flu.
- To evaluate clinical, radiological, and spirometric parameters in these cases.
Main Methods:
- Case report of two patients with confirmed swine flu.
- Recording of clinical and laboratory data.
- Assessment of radiological imaging and spirometry over time.
Main Results:
- Both reported cases exhibited residual pulmonary fibrosis after swine flu.
- No deterioration in radiological findings was observed.
- Spirometric values remained stable, indicating no decline in lung function.
Conclusions:
- Pulmonary fibrosis resulting from swine flu (H1N1) pneumonia appears to be a non-progressive condition.
- Long-term follow-up suggests stability in lung fibrosis post-infection.

1.0K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

2.2K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

820
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
