Clinical trials have revealed that Ivacaftor significantly reduces sweat chloride in patients with cystic fibrosis who carry the G551D mutation. This finding has been incorporated into the commissioning guidelines in the UK with a sweat chloride reduction of 30% or below 60 mmol/L, specified as the main criteria for continued funding of Ivacaftor for(More)
There are several methods available to the clinician to assess severity of lung disease in cystic fibrosis (CF). Here we present a case where several of these modalities appeared to be discordant. As in this case, many assessments of respiratory status may be necessary to fully evaluate patients with CF. Spirometry may be insensitive to significant changes(More)
