Plain English Summary

Background and study aims
Tiny particles in the air that cause allergies such as dust mite and pollen or those from cats and pollutants from traffic exhaust fumes can lead to health problems. Avoidance of these tiny particles can improve health. Unfortunately, complete avoidance of these particles inside the home is often not possible. In this study, we shall test a new treatment called Airsonett, for removing these particles in the air, on children.

Who can participate?
Children aged 2–16 years old with severe skin allergies

What does the study involve?
Airsonett will be installed in the rooms of participants, so that they are surrounded by clean and slightly cooler air while they are sleeping.

What are the possible benefits and risks of participating?
A benefit is the avoidance of particles in the air that cause allergies. Risks were not provided at the time of registration.

Where is the study run from?
Imperial College Health Care NHS Trust (UK)

When is the study starting and how long is it expected to run for?
From January 2015 to December 2018

Who is funding the study?
Imperial College Biomedical Research Centre (UK)

Study information

Scientific title

Temperature controlled laminar airflow treatment in children with severe atopic eczema: a pilot study


Study hypothesis

Temperature controlled laminar airflow (TLA) treatment improves severe eczema in children, leading to reduced health care use, better sleep and quality of life

Ethics approval

Local research ethics committee (London-Fulham) number 14/LO/0130

Study design

Single centre open-label extended pilot study

Primary study design


Secondary study design

Non randomised study

Trial setting


Trial type


Patient information sheet


1. Severe atopic eczema, treatment resistant or dependent on potent topical/systemic therapy
2. Most participants will have multiple allergic comorbidities, such as allergic rhino conjunctivitis, asthma and food allergies


1. A TLA device (Airsonett) will be installed for all participants
2. Airsonett is a European Union registered medical device and has been approved in the United Kingdom for use by consumers; it produces highly filtered clean air that is 0·5°C cooler than the rest of the air in the room; this cooler air surrounds individual while he or she is sleeping and filters the tiny particles and allergens in their breathing zone (i.e., the air a person would breathe in) during sleep
3. In the week before and after the installation of the TLA device, aeroallergen sampling will take place and a novel home sleep-study device will be in place to assess changes in sleep quality
4. Participants will have detailed clinical follow-up

Intervention type



Drug names

Primary outcome measure

Improvement in sleep and pruritus (SCORAD-C, visual analogue score)
Measured at 1 month, 3 months, 6 months, 12 months.

Secondary outcome measures

1. Reduction in Health Care Utilisation
2. Cost score combining medication requirement and unscheduled healthcare visits
3. Improvement in eczema related quality of life (validated questionnaires: CDQoL, FDI)
4. Change in allergen exposure during TLA use in home environment (particle counting, airsampling)
5. Improvement in rhinitis related quality of life. (Paed RQLQ)
6. Change in sleep quality as assessed by home sleep study (Sonomat)

All Outcomes measured at 1 month, 3 months, 6 months, 12 months.
1. Sonomat Outcome, measured at 3-4 days post treatment start.
2.Change in allergen exposure, measured at 3-4 days post treatment start.
