Preschool children with a history of wheeze, aged 1 to 5 years old
This is a pragmatic, observational study involving preschool children with wheeze aged one to five years old. All treatment and routine monitoring decisions will be at the discretion of their treating general practitioner (GP) or paediatrician (as per usual clinical practice), blinded to the study measurements. The following three biomarker tests will be performed a) atopic sensitisation, b) blood eosinophil count and c) FeNO (off-line method). |
Peripheral blood eosinophil count will be measured from a finger prick blood sample, using the Haemocue machine, allowing a result in approximately 2 minutes.
The test will allow to assess the presence or not of eosinophilia and if it can predict future wheezing exacerbations and response to inhaled corticosteroids (ICS).
Skin prick tests will be performed to: (a) house dust mite, (b) grass pollen, (c) tree pollen, (d) cat hair, (e) dog hair, as well as normal saline and histamine which will act as negative and positive controls respectively.
In addition, skin prick tests will allow the assessment of which aeroallergen is the most useful predictor of outcomes in preschool children.
The child will breathe normally into a sample bag that will be collected for later analysis of FeNO levels.
The test will be performed twice.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Acute attacks of wheeze defined as requiring an unscheduled health care visit
Time Frame: 1 year follow-up period
|
Exacerbation of the wheezing condition that will require a visit to a hospital that was not scheduled.
This will be determined with monthly electronic questionnaires sent by email to the parents of preschool children with wheeze, as well as by follow-up face-to-face visits in primary care every 3 months.
|
1 year follow-up period
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Carer days off work
Time Frame: 1 year follow-up period
|
Days the parent/carer has taken off work in order to be with their child that has an acute wheezing.
This will be determined with monthly electronic questionnaires sent by email to the parents of preschool children with wheeze, as well as by follow-up face-to-face visits in primary care every 3 months.
|
1 year follow-up period
|
Children unable to attend childcare facility
Time Frame: 1 year follow-up period
|
Assessing the number of days a child did not attend a childcare facility due to exacerbation of his/her wheezing condition.
This will be determined with monthly electronic questionnaires sent by email to the parents of preschool children with wheeze, as well as by follow-up face-to-face visits in primary care every 3 months.
|
1 year follow-up period
|
Use of oral corticosteroids
Time Frame: 1 year follow-up period
|
In case a child has been prescribed oral corticosteroids, this has to be declared so that we can assess treatment effectiveness according to the biomarkers tested.
This will be determined with monthly electronic questionnaires sent by email to the parents of preschool children with wheeze, as well as by follow-up face-to-face visits in primary care every 3 months.
|
1 year follow-up period
|
Use of inhaled β-2 agonist (rescue therapy)
Time Frame: 1 year follow-up period
|
In case a child has been prescribed β-2 agonists, this has to be declared so that we can assess treatment effectiveness according to the biomarkers tested.
This will be determined with monthly electronic questionnaires sent by email to the parents of preschool children with wheeze, as well as by follow-up face-to-face visits in primary care every 3 months.
|
1 year follow-up period
|
Assessment id respiratory or wheezing condition is under control
Time Frame: 1 year follow-up period
|
• Assessment if children's respiratory or wheezing condition is under control by using the TRACKTM score questionnaire (Test for Respiratory and Asthma Control in Kids)
|
1 year follow-up period
