Plain English Summary
Background and study aims
About 20% of children in western European countries have atopic dermatitis (AD) (eczema), often as part of the atopic syndrome (a tendency to develop allergy). Some children continue to have symptoms despite best treatment. We want to provide new treatment options for these children. We are carrying out a study to compare two different new treatments for children with moderate to severe atopic dermatitis. Our goal is to find the most favourable treatment for children with AD. The study's findings should help to improve the quality of life of children with moderate to severe AD.
Who can participate?
Children between 8 and 18 years of age, with moderate to severe AD and asthma, from the Netherlands, can participate in this study.
What does the study involve?
In this study, two treatments are compared. One is a 6-week treatment at the outpatient clinic of the University Medical Centre, Utrecht in the Netherlands. The other is a 6-week treatment at the Dutch Asthma Centre Davos in Switzerland. The treatment that the participant will receive is decided by a process called randomisation, which is like a coin toss. After the treatment period, participants are followed up immediately after the treatment, 6 weeks and 6 months after the treatment. At these time points, we ask the participant to fill in questionnaires, blood and skin samples are taken and a lung function test is done.
What are the possible benefits and risks of participating?
Possible benefits of participating in the study are treatment for the disease, coping with the disease in a better way and improved quality of life. Long-term benefits are that new treatment will become available for all children with moderate to severe AD. There are no direct risks of participating in this study.
Where is the study run from?
The trial has been set up by the University Medical Centre, Utrecht, Netherlands in collaboration with the Dutch Asthma Centre Davos, Switzerland.
When is the study starting and how long is it expected to run for?
The study started in September 2010 and is expected to run until the summer of 2014.
Who is funding the study?
The University Medical Center Utrecht, MEREM, Vrienden van het WKZ, the European Allergy Clinic Davos and Vereniging Nederland Davos.

Study information
Scientific title
A pragmatic randomized controlled trial comparing high altitude treatment with current best care in children with moderate to severe atopic dermatitis (and asthma) in the Netherlands: multidisciplinary treatment at the high altitude clinic Dutch Asthma Centre Davos, Switzerland versus the Wilhelmina Childrens Hospital Utrecht, the Netherlands
Acronym
DAVOS
Study hypothesis
Multidisciplinary treatment for 6 weeks at the Dutch Asthma Centre Davos will improve disease coping and acceptance and quality of life of children with AD more than multidisciplinary treatment in the Wilhelmina Childrens Hospital. The null hypothesis we test is that there is no difference between the effects of both treatments.
On 03/12/2013 the following changes were made to the trial record:
1. The scientific title was changed from 'A randomised controlled trial comparing high altitude treatment with current best care in children with atopic dermatitis and asthma within the atopic syndrome in the Netherlands. Multidisciplinary treatment at the high altitude clinic Dutch Asthma Centre Davos, Switzerland versus the Wilhelmina Childrens Hospital Utrecht, the Netherlands: a national study' to 'A pragmatic randomized controlled trial comparing high altitude treatment with current best care in children with moderate to severe atopic dermatitis (and asthma) in the Netherlands: multidisciplinary treatment at the high altitude clinic Dutch Asthma Centre Davos, Switzerland versus the Wilhelmina Childrens Hospital Utrecht, the Netherlands'.
2. The anticipated end date was changed from 01/02/2015 to 01/06/2015.

Primary outcome measures
Current primary outcome measures as of 03/12/2013:
1. Disease coping and acceptance, measured with the COPEKI/JUCCKI questionnaire
2. Disease-specific quality of life, measured with Children's Dermatology Life Quality Index (CDQLI)
3. Self Administered Eczema Area and Severity Index (SA-EASI)
All measured before the intervention, directly after the intervention, 6 weeks after the intervention and 6 months after the intervention
Previous primary outcome measures:
1. Disease coping and acceptance, measured with the COPEKI/JUCCKI questionnaire directly after the intervention and 6 months after the intervention
2. Disease-specific quality of life, measured with Children's Dermatology Life Quality Index (CDQLI) directly after the intervention, 6 weeks after the intervention and 6 months after the intervention
Secondary outcome measures
