Consequences of COVID 19 Pandemic on Childhood Asthma
Consequences of COVID 19 Pandemic on Childhood Asthma
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.
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.
Inclusion Criteria:

 -  Children and adolescents aged 3 to 16 years old

 -  With a medical diagnosis of asthma as per-guidelines, who had been followed-up for at
 least 6 months,

 -  Assessed in one of the pediatric departments participating in the study,

 -  After written consent of at least one of the 2 parents and/or representative of the
 parental authority, and of the child if he is older than 8 years old.

 Criteria for the sub-population assessed at "exacerbation" and second visit:

 -  Children and adolescents aged 3 to 16 years

 -  With a medical diagnosis of asthma as per-guidelines, who had been followed-up for at
 least 6 months,

 -  Hospitalized for a severe asthma exacerbation (requiring hospitalization and general
 corticosteroid therapy) at Lille University Hospital

 -  After written consent of both parents and/or representative of the parental authority,
 and of the child if he is over 8 years old

 Exclusion Criteria:

 -  History of chronic respiratory disease other than asthma,

 -  Inability of parents to receive informed information, inability to participate in the
 entire study, refusal to sign the consent form
