The respiratory consequences of COVID-19 lasted for a median of 4 months in a cohort of children aged 2-18 years of age
Abstract
AIM: We focused on the clinical picture, severity and prognosis of children who experienced long-term respiratory issues after COVID-19. METHODS: This was a national Czech multicentre study of paediatric post-COVID syndrome, which used a standard protocol to evaluate structural and functional anomalies and exclude alternative diagnoses.
From 6 January to 30 June 2021, 11 paediatric pulmonologists enrolled all paediatric referrals aged 2-18 years with persistent respiratory symptoms more than 12 weeks after COVID-19, namely cough, dyspnoea and chest pain. Medical histories were taken and physical examinations, lung function testing, chest X-ray and blood tests were performed.
RESULTS: The dominant symptoms in the 39 children (56.4% girls) were exertional dyspnoea (76.9%) and a chronic cough (48.7%), while dyspnoea at rest (30.8%) and chest pain (17.9%) were less prevalent. More than half (53.8%) reported more than 1 symptom and 38.5% had abnormal results for 1 of the following tests: lung function, chest X-ray or D-dimers.
The median age of the children was 13.5 years (interquartile range +-4.8 years) and the median recovery time was 4 months (range 1.5-8 months). CONCLUSION: Our initial data suggest that the long-term respiratory impact of COVID-19 was relatively mild in our cohort, with a favourable prognosis.
