Background Inhaled hypertonic saline acutely increases mucociliaryclearance and, in short-term trials, improves lung functionin people with cystic fibrosis. We tested the safety and efficacyof inhaled hypertonic saline in a long-term trial.
Methods In this double-blind, parallel-group trial, 164 patientswith stable cystic fibrosis who were at least six years oldwere randomly assigned to inhale 4 ml of either 7 percent hypertonicsaline or 0.9 percent (control) saline twice daily for 48 weeks,with quinine sulfate (0.25 mg per milliliter) added to eachsolution to mask the taste. A bronchodilator was given beforeeach dose, and other standard therapies were continued duringthe trial.
Results The primary outcome measure, the rate of change (slope)in lung function (reflected by the forced vital capacity [FVC],forced expiratory volume in one second [FEV1], and forced expiratoryflow at 25 to 75 percent of FVC [FEF2575]) during the48 weeks of treatment, did not differ significantly betweengroups (P=0.79). However, the absolute difference in lung functionbetween groups was significant (P=0.03) when averaged acrossall post-randomization visits in the 48-week treatment period.As compared with the control group, the hypertonic-saline grouphad significantly higher FVC (by 82 ml; 95 percent confidenceinterval, 12 to 153) and FEV1 (by 68 ml; 95 percent confidenceinterval, 3 to 132) values, but similar FEF2575 values.The hypertonic-saline group also had significantly fewer pulmonaryexacerbations (relative reduction, 56 percent; P=0.02) and asignificantly higher percentage of patients without exacerbations(76 percent, as compared with 62 percent in the control group;P=0.03). Hypertonic saline was not associated with worseningbacterial infection or inflammation.
Conclusions Hypertonic saline preceded by a bronchodilator isan inexpensive, safe, and effective additional therapy for patientswith cystic fibrosis. (ClinicalTrials.gov number, NCT00271310
