Study design (if review, criteria of inclusion for studies)
20 week, placebo-controlled, and randomized, double blind, crossover trial
Participants
12 CF patients, aged 6-29
Interventions
montelukast or placebo
Outcome measures
At first and last week of each treatment course spirometry and whole body plethysmography parameters (FEV1, PEF, FEF25/75%, VC, TGV, Raw and RV) and clinical wheezing and cough scale were measured.
Main results
In montelukast group significant improvement in FEV1 (mean +/- SD, 54.6 +/- 22.6 before and 62 +/- 19.0 after treatment, p=0.0112) and FEF25/75% (28.9 +/- 23.0 before and 37.5 +/- 25.5 after treatment, p=0.0053) were observed. Compared with placebo montelukast significantly improved FEV1 (p=0.0032), PEF (p=0.0298) and FEF25/75% (p=0.0091). There was no significant difference in VC, TGV, Raw and RV. Montelukast compared with placebo significantly decreased cough (p<0.0001) and wheezing (p=0.0002) score.
