Scientific titleA single-blind placebo-controlled trial to determine the effect of the airsonett airshower on sleep quality
Study objectives1. In adults with allergic rhinitis sensitised to dust mite, cat or dog and with significant rhinitis-related sleep disturbance (NRQLQ=3), treatment with nocturnal temperature-controlled laminar airflow (TLA) results in improved total symptom score compared to placebo device, on the second night of treatment.
2. In adults with allergic rhinitis sensitised to dust mite, cat or dog and with significant rhinitis-related sleep disturbance (NRQLQ=3), nocturnal TLA results in reduced nasal IL-5, reduced diurnal variation in peak nasal inspiratory flow, reduced nasal nitric oxide (NO), reduced modified NRQLQ score (i.e. scored over past 48 hours rather than 1 week), improved sleep parameters as measured by polysomnography and the Somnomat.
Ethics approval(s)Scotland A Research Ethics Committee, 28/02/2011, ref: 11/MRE00/6
Health condition(s) or problem(s) studiedAllergic rhinitis
Intervention1. Four nights of study – two with placebo Protexo device and two with active Protexo device
2. Allerguard pillow protectors to be used on all four nights
Intervention typeOther
Primary outcome measure(s)

Total nasal symptom score (itching, sneezing, rhinorrhoea, congestion rated as none=0, mild=1, moderate=2, severe=3)

Key secondary outcome measure(s)

1. Arousal index as measured by polysomnography
2. Other polysomnography parameters
3. Spirometry
4. Exhaled NO, nasal NO as measured by NIOX MINO device
5. Peak nasal inspiratory flow
6. Nasal inflammometry – nasal secretions collected bilaterally using filter paper strips (7x30 mm)
7. Somnomat
8. Visual analogue scale for sleepiness – 100 mm scale from extremely sleepy (0 mm) to not sleepy at all (100 mm)
9. Visual analogue scale for sleep quality – 100 mm scale from worst night’s sleep ever (0 mm) to best night’s sleep ever (100 mm)
