Consequences of COVID 19 Pandemic on Childhood Asthma

Conditions
Asthma in Children
Registration Number
NCT04821908
Lead Sponsor
University Hospital, Lille
Brief Summary

The SARS-CoV2 pandemic, which emerged in the first quarter of 2020, has led to an unprecedented health crisis in our modern healthcare systems and has resulted in strong national public health measures. The impact of the pandemic and its indirect environmental consequences on pediatric asthma is currently being assessed. In particular, the study of its role on the risk of exacerbations and modification of control is one of the priority research objectives defined by European societies.

The primary aim is to study the impact of the pandemic on asthma control in children aged 3-16 years with a medical diagnosis of asthma, compared to data from other observational cohorts conducted in the same region prior to the pandemic.

A sub-population of children 3-16 years will be assessed at exacerbation and at a follow-up visit, 2-4 months later, with clinical data, biological and microbiological samples.

Detailed Description

Children aged 3-16 years with a medical diagnosis of asthma, will be assessed for asthma control, exacerbation rate.

Data will be compared to data from other observational cohorts conducted in the same region prior to the pandemic.

A sub-population of children 3-16 years will be assessed at exacerbation and at a follow-up visit, 2-4 months later, with clinical data, biological and microbiological samples.

Primary Outcome Measures
NameTimeMethod
Controlled asthmaat inclusion

Composite criteria defined by a cACT (4-11 years) or ACT (12-16 years) score ≥ 20 and according to GINA criteria.

Secondary Outcome Measures
NameTimeMethod
Characteristics of asthmaAt inclusion and follow-up visit at 2-4 months for the sub-population included at exacerbation

Composite criteria : allergic phenotype, severity assessed by GINA treatment level, number of exacerbations in the past year, lung function

number of infectious episodes in the past yearAt inclusion and Follow-up visit at 2-4 months for the sub-population included at exacerbation

number of infectious episodes based on patient report

ObservanceAt Inclusion and Follow-up visit at 2-4 months for the sub-population included at exacerbation

Assessed by four-items Morisky-Green questionnaire : 1/ Do you ever forget to take your medication; 2/ Are you careless sometimes about taking your medication 3/ When you feel better, do you sometimes stop taking your medication 4/ Sometimes, if you feel worse when you take your medication, do you stop taking it. An answer "no" to any of the 4 questions is considered as "not well-observed medication".

QoL (Quality of life) in children aged 7-17 yearsAt Inclusion and Follow-up visit at 2-4 months for the sub-population included at exacerbation

Assessed by PAQLQ : PAEDIATRIC ASTHMA QUALITY OF LIFE QUESTIONNAIRE. The PAQLQ has 23 questions in 3 domains (symptoms, activity limitation and emotional function). The activity domain contains 3 'patient-specific' questions. Children are asked to think about how they have been during the previous week and to respond to each of the 32 questions on a 7-point scale (7 = not bothered at all -

1 = extremely bothered). The overall PAQLQ score is the mean of all 23 responses and the individual domain scores are the means of the items in those domains. The highest the score is, the better QoL is.

Outdoor levels of pollutants and pollensAt Inclusion and Follow-up visit at 2-4 months for the sub-population included at exacerbation

Composite criteria : monthly average measurements of CO, O3, NO, NO2, SO2, PM2.5, PM10 and pollen counts

history of SARS-Cov2 infection in the past yearAt inclusion and Follow-up visit at 2-4 months for the sub-population included at exacerbation

history of SARS-Cov2 infection based on patient report

Respiratory virus infection (SARS-CoV2 and other)at exacerbation and at follow-up visit at 2-4 months for the sub-population included at exacerbation
