Plain English Summary
Background and study aims
This project looks at whether some babies born early can have long-term breathing problems as they go through childhood which have not yet been detected. Research on very premature babies has shown that their lungs may not work as well as babies born at, or earlier to, their due date. Work already done by the researchers of this project has also shown that some moderately premature babies are at risk of having breathing problems as they grow up. The next step of this research is to invite some families to participate in a study to look at possible reasons why children born early may have breathing problems. The researchers want to know whether there are differences in the structure and function of the airways in the children born prematurely compared to those born on time. If prematurely born children are different, they may benefit from closer follow-up and possibly some treatment to improve their breathing.
Who can participate?
Children (and families) aged between 7-12 who were born prematurely (at 34 weeks gestation or less)
What does the study involve
First of all, each child does some breathing tests (at home, if possible) and both them and their parents are asked to fill in some questionnaires about their daily life. A sample of saliva (spit) is also collected. The aim of the visit is to assess how many children have lower than expected results on the breathing test. Children will a lower than expected result are asked to take part in the next stage. For this stage, each child and their parents visit the laboratory on two occasions to have more detailed breathing tests before and after exercising on a stationary bicycle. After the first visit, each child is given an inhaler to use twice a day for 12 weeks. The type of inhaler they are given is allocated randomly and could be one containing fluticasone proprionate, a fluticasone proprionate/salmeterol xinafoate combination or a placebo (dummy inhaler). Any response to the inhaler treatment will be seen at the second visit. Finally, some children are invited to have a MRI scan of their lungs to look at how well they are working.
What are the benefits and risks?
The researchers aim to show that children born early have limitations in their lung function which may cause breathing problems. If so, they will be able to find out if treating with medicine is successful in easing the symptoms. Children born preterm have generally been ignored, however the evidence from this study may indicate to healthcare policy makers that closer follow-up is required in these children; secondly, it may indicate that treatment should be considered an option in all children born preterm, (extremely or moderately) with reduced lung function. In the future, this surveillance and treatment may reduce the burden on NHS resources in terms of GP and hospital visits. As with all medicines, there are some small risks of side effects. However these are rare and often mild.

Study hypothesis
The overall aim is to establish the underlying mechanisms of chronic airway obstruction observed in symptomatic children who are born preterm and to establish if there are different phenotypes of this condition that do or do not respond to standard inhaled therapy.

2. Fluticasone proprionate/salmeterol xinafoate combination
3. Placebo
Intervention type
Drug
Phase

Drug names
1. Fluticasone proprionate

Primary outcome measures
The primary outcome will be the difference in pre and post treatment percent predicted FEV1 after 12 weeks of therapy between the active and placebo groups
Secondary outcome measures
1. Differences in measures of obstructive airway disease (pulmonary function tests)
2. Differences in response to exercise challenge between treatment groups.
3. Differences in biomarkers of airway inflammation between treatment groups
4. Differences in respiratory and neurological symptoms (questionnaire)
5. MRI parameters: apparent diffusion coefficient (ADC) between 3 comparison groups (preterm, FEV1 ≤85% at baseline; preterm control, FEV1 ±1 standard deviation from normal; and term control, FEV1 ±1 standard deviation from normal).
6. Pre- and- post treatment differences in objectively measured physical activity
7. Adverse events
All outcomes to be measured after 12 weeks of therapy between the active and placebo groups
