Progressive pulmonary disease is the primary cause of morbidity and mortality in adult patients with cystic fibrosis (CF). The decrease in lung function associated with infection with Pseudomonas aeruginosa has been related to the severity of pulmonary inflammation. Thus therapies that reduce pulmonary inflammation may prove to be clinically efficacious. Therapeutic interventions that target pulmonary inflammation may be directed either at the infecting organism, especially P aeruginosa, or at host responses. Eradication of P aeruginosa from the airways of patients with CF has not been accomplished. However, reduction of the burden of P aeruginosa or modification of virulence factors are practical goals. Normalization of the host response ultimately depends on correction of the molecular defect. Until then, therapies are bein investigated that may modulate pulmonary inflammation. These include therapies aimed at compensating for the defect in ion transport, down-regulating inflammatory cell responses, inhibiting host inflammatory products, or altering airway secretions. Preliminary data suggest that each of these approaches may have clinical efficacy. Large, multicenter trials addressing these issues are presently ongoing and hold the promise for continued improvement in the clinical course of patients with CF.
