Clinical characteristics, treatment and outcomes of paediatric COVID-19: a systematic review

22 April, 2021

A recent BBC news item noted last week 'Despite the overwhelming evidence that Covid-19 rarely kills young children, in Brazil 1,300 babies have died from the virus'. https://www.bbc.co.uk/news/world-latin-america-56696907

This new OA paper in Archives of Disease in Childhood gives a global picture. The paper is based on data prior to the Brazil report. We hope that the latter does not indicate a trend.

ABSTRACT

Objective: Compare paediatric COVID-19 disease characteristics, management and outcomes according to World Bank country income level and disease severity.

Design: Systematic review and meta-analysis.

Setting: Between 1 December 2019 and 8 January 2021, 3350 articles were identified. Two reviewers conducted study screening, data abstraction and quality assessment independently and in duplicate. Observational studies describing laboratory-confirmed paediatric (0–19 years old) COVID-19 were considered for inclusion.

Main outcomes and measures: The pooled proportions of clinical findings, treatment and outcomes were compared according to World Bank country income level and reported disease severity.

Results: 129 studies were included from 31 countries comprising 10 251 children of which 57.4% were hospitalised. Mean age was 7.0 years (SD 3.6), and 27.1% had a comorbidity. Fever (63.3%) and cough (33.7%) were common. Of 3670 cases, 44.1% had radiographic abnormalities. The majority of cases recovered (88.9%); however, 96 hospitalised children died. Compared with high-income countries, in low-income and middle-income countries, a lower proportion of cases were admitted to intensive care units (ICUs) (9.9% vs 26.0%) yet pooled proportion of deaths among hospitalised children was higher (relative risk 2.14, 95% CI 1.43 to 3.20). Children with severe disease received antimicrobials, inotropes and anti-inflammatory agents more frequently than those with non-severe disease. Subgroup analyses showed that a higher proportion of children with multisystem inflammatory syndrome (MIS-C) were admitted to ICU (47.1% vs 22.9%) and a higher proportion of hospitalised children with MIS-C died (4.8% vs 3.6%) compared with the overall sample.

Conclusion: Paediatric COVID-19 has a favourable prognosis. Further severe disease characterisation in children is needed globally.
