Acute Pseudomonas aeruginosa pneumonia associated with cystic fibrosis

Acute *Pseudomonas aeruginosa* pneumonia associated with cystic fibrosis refers to a severe lower respiratory tract infection caused by the opportunistic Gram-negative pathogen *Pseudomonas aeruginosa* in individuals with the genetic disorder cystic fibrosis

Acute *Pseudomonas aeruginosa* pneumonia associated with cystic fibrosis refers to a severe lower respiratory tract infection caused by the opportunistic Gram-negative pathogen *Pseudomonas aeruginosa* in individuals with the genetic disorder cystic fibrosis In this population, defective cystic fibrosis transmembrane conductance regulator (CFTR) function results in dehydrated, viscous airway secretions and impaired mucociliary clearance, creating an ideal niche for rapid bacterial proliferation ...

Clinically, it manifests as an acute pulmonary exacerbation marked by sudden clinical decline, increased cough, changes in sputum production or purulence, tachypnea, dyspnea, and systemic signs such as fever and weight loss Pathophysiologically, the infection induces intense neutrophilic inflammation, tissue destruction, and alveolar consolidation, which can precipitate respiratory failure and accelerate progressive irreversible loss of lung function
