Effect of Posture on Lung Ventilation distribution and Associations with Structure in Children with Cystic Fibrosis
We investigated whether sitting or lying down changes how well air mixes in the lung during normal breathing using the multiple breath washout test in healthy children or children with cystic fibrosis. We also studied whether posture (sitting or lying down) impacts on the relationships between lung function (normally measured with the child seated) and lung structure (normally measured with the child lying down) in children with cystic fibrosis. Specifically, we studied whether lung function better reflects the structural lung damage on chest CT when both the tests are performed lying down.
The multiple breath washout test was performed in 25 healthy children and 21 children with cystic fibrosis both seated and lying down. Children with cystic fibrosis also underwent a chest CT scan (lying down).
We found that lying down increased the amount of uneven gas mixing in the lung, indicated by an increase in a measure called lung clearance index. We found a larger increase in the lung clearance index in children with cystic fibrosis compared with healthy children. In children with cystic fibrosis, the measure of lung function more closely corresponded to the measure of lung structure (the CT scan) when both tests were performed lying down.
Our data show that the multiple breath washout test gives different results depending on whether the child is sitting up or lying down during the test. When the child is lying down, gas in the lung mixes unevenly. This could be caused by smaller lung volume, narrowing and closure of airways, and trapped air in the lung. Our results suggest that performing the multiple breath washout test lying down may give a more accurate estimate of structural lung damage than performing the same test sitting up. Further work is needed to confirm these findings in a larger population of individuals, including individuals with more severe cystic fibrosis lung disease.

Multiple Breath Washout Outcomes Are Sensitive to Inflammation and Infection in Children with Cystic Fibrosis
The multiple breath washout technique is a lung function test that tells us how evenly gas mixes in the lung. In diseased lungs, regions of the lungs can be either partially or completely closed resulting in less gas mixing in these regions and uneven gas mixing in the lung. The lung clearance index is a measure of how evenly gas mixes in the lung, with higher values indicating uneven mixing and worse lung function.
We assessed whether the lung clearance index would be higher in preschool children with cystic fibrosis compared with healthy children. We also assessed whether the lung clearance index would be higher in children with cystic fibrosis who had detectable inflammation and infection in the lungs compared to those without.
We performed the multiple breath washout test in 82 visits with 58 children with cystic fibrosis and 38 visits with 31 healthy children aged three to six years. Children with cystic fibrosis also underwent bronchoalveolar lavage collection for detection of lower respiratory tract inflammation and infection.
The lung clearance index was higher in children with cystic fibrosis compared with healthy controls. In children with cystic fibrosis, the lung clearance index was higher in those with lower respiratory tract infections and inflammation detected in the lung.
Our data indicates that the lung clearance index is sensitive to the presence and extent of inflammation and respiratory pathogens in bronchoalveolar lavage fluid in preschool children with cystic fibrosis. The lung clearance index may be an important tool for monitoring clinical status and response to therapeutic interventions in preschool children with cystic fibrosis.

Does 100% oxygen change the way children breathe?
The multiple breath washout lung function test relies on normal breathing of 100% oxygen to measure if gas exchange occurring in the lungs is normal. It is known that breathing 100% oxygen changes the way babies breath, but this does not occur in school-aged children and adults. We wanted to understand if there were changes in breathing pattern in preschool-aged children as this may impact the results of the lung function test.
We used data from children in AREST CF aged 3 to 6 years who performed the multiple breath washout lung function test and found very small changes in breathing pattern. These small changes are not likely to affect the results from the multiple breath washout lung function test.

The lack of the presence of Small colony variants of S.aureus in lower respiratory tract.
Lung infection with the bacterium Staphylococcus aureus (S.aureus) is a frequent problem for patients with Cystic fibrosis (CF) and is commonly treated with antibiotics. However, S.aureus may evolve and adapt to their environment in the lung by slowing down their growth and appearing smaller in size, aptly named “small-colony variants of Staphylococcus aureus” or SCVs of S.aureus.
Studies have found that SCVs of S.aureus are associated with worse lung disease in children with CF and have a higher resistance to antibiotics compared to the “normal” strain of S.aureus.
It was important to find out if these SCVs of S.aureus were also present in young children with CF in our clinics as they are not tested for in routine hospital laboratories and their presence is unknown.
We studied 277 lower airway samples collected from 124 patients with CF undergoing routine tests, during 2014-2015 at the RCH in Melbourne for microbiology analysis.
Sixty-one (22%) of these samples were infected with a “normal” strain of S. aureus, butno SCVs of S.aureuswere found.
We concluded that SCVs of S.aureus were not commonly found and does not appear to pose a problem in young children with CF in our centre
