How does chronic infection contribute to the progression of bronchiectasis?

Answer 18

Chronic infection contributes to bronchiectasis by causing: - Ongoing inflammation and immune response - Damage to lung tissue and architecture - Impaired mucus clearance, leading to further infections - Cycle of infection and inflammation, worsening lung function over time

Question 19

How does nutritional support play a role in managing cystic fibrosis?

Answer 19

Nutritional support in cystic fibrosis is crucial because it helps manage malabsorption and vitamin deficiencies, particularly fat-soluble vitamins A, D, E, and K. Adequate nutrition supports growth, immune function, and overall health, improving quality of life and potentially reducing complications.

Question 20

What is the pathophysiology of Cystic Fibrosis (CF)?

Answer 20

Cystic Fibrosis (CF) is caused by mutations in the CFTR gene, leading to abnormal chloride transport. This results in thick mucus in organs, causing respiratory infections, pancreatic dysfunction, and digestive issues. Bronchiectasis develops from recurrent infections and impaired mucus clearance, leading to lung damage.

Answer 26

The two main factors required for the development of bronchiectasis are: - An infectious insult - Impaired drainage, obstruction, or a defect in host defense

Question 27

How do mutations in the CFTR gene affect chloride transport?

Answer 27

Mutations in the CFTR gene disrupt chloride transport, leading to thickened secretions in various organs. This causes issues like airway obstruction, recurrent infections, and inflammation, particularly in the lungs, contributing to cystic fibrosis symptoms and complications.

Question 28

How can psychological support assist patients with chronic respiratory conditions like cystic fibrosis?

Answer 28

Psychological support can assist patients with chronic respiratory conditions like cystic fibrosis by: - Reducing anxiety and depression - Improving coping strategies - Enhancing treatment adherence - Providing education about the condition - Offering support for family dynamics and social interactions

Question 31

What role do immunoglobulin levels play in diagnosing bronchiectasis?

Answer 31

Immunoglobulin levels help diagnose bronchiectasis by indicating immune function. Decreased levels of IgA, IgG, and IgM suggest impaired host defense, which can contribute to the development of bronchiectasis. Testing these levels aids in identifying underlying causes and assessing disease severity.

Question 32

How should acute exacerbations of bronchiectasis be treated?

Answer 32

Acute exacerbations of bronchiectasis should be treated with: - Respiratory support (oxygen, NIV) - Early and aggressive antimicrobial therapy based on sputum culture - Consider ICU referral if severe - Manage symptoms and optimize lung function

Answer 33

Imaging techniques for assessing bronchiectasis severity include: - High-Resolution CT (HRCT): primary method for visualizing airway dilation and structural changes. - Chest X-ray: initial assessment tool, less detailed than HRCT. - MRI: occasionally used for specific cases.

Question 34

How does CF lead to pulmonary and extra-pulmonary organ dysfunction?

Answer 34

Cystic Fibrosis (CF) leads to pulmonary dysfunction through thick mucus obstructing airways, causing infections and inflammation. Extra-pulmonary dysfunction occurs due to malabsorption, pancreatic insufficiency, and reproductive issues, affecting multiple organs and systems throughout the body.
