Plain English Summary

Background and study aims
Eczema is a condition that causes the skin to become itchy, red, dry and cracked. Specialist silk clothing has been promoted recently as a new treatment option for people with eczema, but it is unclear if these garments really do provide additional benefits for patients. Research is needed to find out whether or not these new products live up to the impressive claims that are currently being made. As a result, we are about to conduct a study of silk clothing for the management of eczema in children.

Who can participate?
Children between 1 and 15 years of age who have quite bad eczema.

What does the study involve?
Each child will be enrolled in the study for 8 months in total, and will be asked to attend their local recruiting hospital on four different occasions. Children participating in the study will be put into one of two groups. The first group will receive three sets of silk underwear – this will be either a bodysuit and leggings, or vest and leggings depending on the child’s age. The children will be asked to wear the clothing underneath their normal clothes day and night for six months - if possible! The second group will not receive the clothing straight away but will be given the clothing to try for themselves after the first 6 months of the study has finished. Throughout the study all of the children will be free to continue with their usual eczema treatments, such as emollients and topical steroids, and will be asked to complete a weekly questionnaire at home so that they can tell us how the eczema has been, and how often the clothing has been worn.

What are the possible benefits and risks of participating?
If we can show that these clothes provide additional benefits for patients, then this would be an important finding, and many eczema sufferers could benefit. Equally, if the research shows that the clothes provide no useful benefit, then patients and the NHS can save money by not using treatments that have been shown to be ineffective.

Where is the study run from?
Recruitment is taking place in hospitals in five main areas – Nottingham, Cambridge, north London, Portsmouth and the Isle of Wight. This study is being led from the Centre of Evidence Based Dermatology at the University of Nottingham, and will be co-ordinated from the Nottingham Clinical Trials Unit.

When is the study starting and how long is it expected to run for?
Recruitment is due to start in November 2013 and will continue for about 18 months.

Who is funding the study?
National Institute for Health Research (UK)

Study information

Scientific title

Randomised controlled trial of silk therapeutic CLOTHing for the long-term management of Eczema Symptoms in children



Study hypothesis

The purpose of this study is to establish whether silk therapeutic clothing is effective in the long-term management of eczema in children.

Primary Objective
To assess whether silk therapeutic clothing, when used in addition to standard eczema care, reduces eczema severity in children over a period of six months.

Secondary Objective
To estimate the within trial cost-effectiveness of silk therapeutic clothing with standard care, compared to standard care alone, from an NHS and a family perspective.

Children will be randomised into one of two groups - standard care plus silk clothing, or standard care only (for the 6-month RCT period). Participants allocated to standard care will receive the clothing after the 6-month clinic visit, and both groups will be followed up for a further 2 months by questionnaire.

Silk therapeutic clothing, The medical device under investigation is a knitted, sericin-free silk therapeutic garment with a CE mark for use in eczema.

For both arms: duration of treatment is 6 months, duration of follow-up is 8 months
