Pulmonology III. - Dr. Terezia Laszlo

Cystic fibrosis /CF
Sinonims:CF/mucoviscidosis
Pathology:
Inherited disease /CFTR gene on Chromosome 7
transmembrane conductance regulator
anion (Cl−, HCO3 - ) channal dysfunction
impaired chloride transport and enhanced sodium absorption
across airway epithelial cells
thick, sticky mucus
• disease of exocrine gland function
– Mucus-secreting and sweat glands
• that involves multiple organ systems but chiefly results in
chronic respiratory infections, pancreatic enzyme
insufficiency,
• Pulmonary involvement occurs in 90% of patients
• End-stage lung disease is the principal cause of death
CF-symptoms
Abdominal symptoms
Meconium ileus
• Intestinal obstruction
• Failure to thrive (despite adequate appetite)
• Flatulence or foul-smelling flatus, steatorrhea
• Jaundice
• Chr. pancreatitis
Respiratory symptoms
• Cough
• Recurrent wheezing
• Recurrent pneumonia
• Atypical asthma
• Dyspnea on exertion
• Chest pain
Reproductive
• infertility
CF
• sweat has an abnormally high salt content
• The high salt content in perspiration is the basis for
the “sweat test,”
• Abnormal CFTR inhibits the reabsorption of
chloride from sweat into the cells lining the sweat
duct.
• Retention of chloride ‘traps’ sodium ions on the
skin surface leading to characteristic salty sweat

Major Categories of Chronic Interstitial
Lung Disease
Fibrosing
• Usual interstitial pneumonia (idiopathic pulmonary fibrosis)
• Nonspecific interstitial pneumonia
• Cryptogenic organizing pneumonia

• Pneumoconiosis
• Drug reactions
• Radiation pneumonitis
Granulomatous
• Sarcoidosis
• Hypersensitivity pneumonitis
• Eosinophilic
Smoking Related
• Desquamative interstitial pneumonia
• Respiratory bronchiolitis-associated interstitial lung disease

Silicosis
• caused by inhalationof proinflammatory
crystalline silicon dioxide (SiO2) /silica
• that usually presents after decades of
exposure as slowly progressing, nodular,
fibrosing pneumoconiosis.
• Currently, silicosis is the most prevalent
chronic occupational disease in the world.
• Both dose and race are important in
developing
Pathogenesis of silicosis
• After inhalation, the particles are phagocytosed by
macrophages.
• The phagocytosed silica crystals activate
macrophages, leading to the release of
inflammatory mediators,
• particularly IL-1 and IL-18.
