Prevalence and risk factors of post-coronavirus disease 2019 condition among children and adolescents in Japan: A matched case-control study in the general population. Int J Infect Dis 2024; 143:107008. [PMID: 38484930 DOI: 10.1016/j.ijid.2024.107008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/06/2024] [Accepted: 03/08/2024] [Indexed: 04/08/2024] Open
Abstract
OBJECTIVES To examine prevalence and risk factors for post-COVID-19 condition (PCC) in a paediatric population. METHODS The study included patients aged 5-17 years with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection between 1 March 2021 and 30 April 2022 and matched non-infected controls from Yao City, Japan. We compared parent-reported symptoms persisting ≥2 months (present at 3 months post-infection for patients) between the groups. COVID-19 vaccination data was obtained from the Vaccination Registry. RESULTS Among 8167 invited individuals, 3141 (1800 cases, mean age: 10.4 years, 46.1% females; 1341 controls, mean age 10.5 years, 47.1% females) participated. Patients had elapsed average 273 (185-605) days from infection, and 1708 (94.9%) experienced mild acute symptoms. Patients had higher odds of having persistent symptoms than did controls (6.3% vs 2.2%, adjusted odds ratio [aOR]: 3.15, 95% confidence interval: 2.08-4.77), with 53.6% of them reporting current disruption due to the symptoms. Older age, low household income, pre-existing allergy, and autonomic nervous system disease were associated with increased risks of developing PCC; two prior vaccination doses reduced these risks (aOR: 0.53, 0.29-0.96). CONCLUSION SARS-CoV-2 infection, including omicron infections heighten persistent symptom risk in the paediatric population, necessitating preventive strategies, notably vaccination.

Pulmonary Evaluation in Children with Post-COVID-19 Condition Respiratory Symptoms: A Prospective Cohort Study. J Clin Med 2023; 12:6891. [PMID: 37959356 PMCID: PMC10648595 DOI: 10.3390/jcm12216891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 10/22/2023] [Accepted: 10/29/2023] [Indexed: 11/15/2023] Open
Abstract
Background: Studies on post-COVID-19 condition (PCC) in adults have shown deterioration in pulmonary function tests (PFTs), mainly a diffusion limitation. Among the pediatric population, data are scarce. Aim: To characterize PFTs in children with PCC, including changes over time. Methods: A prospective longitudinal study of children with defined PCC and respiratory complaints who were referred to a designated multidisciplinary clinic from 11/2020 to 12/2022. Results: Altogether, 184 children with a mean age of 12.4 years (SD 4.06) were included. A mild obstructive pattern was demonstrated in 19/170 (11%) at presentation, as indicated by spirometry and/or positive exercise challenge test and/or reversibility post bronchodilators, only three had a previous diagnosis of asthma. Lung volumes and diffusion were normal in all but one patient (1/134, 0.7%). Exhaled nitric oxide levels were elevated in 32/144 (22%). A total of 33 children who had repeated PFTs had normal or near-normal PFTs on follow-up testing, including seven (21.2%) who had mild obstructive PFTs at presentation. Multivariate analysis identified older age [OR 1.36 (95% CI:1.07-1.75)], specific imaging findings (prominent bronchovascular markings (OR 43.28 (95% CI: 4.50-416.49)), and hyperinflation (OR 28.42, 95% CI: 2.18-370.84)] as significant predictors of an obstructive pattern on PFTs. Conclusions: In children with PCC and respiratory symptoms, the most common impairment was a mild obstructive pattern; most were without a history of asthma. Improvement was witnessed in long-term follow-up. In contrast to the adult population, no diffusion limitation was found. Empirical periodic inhaler therapy may be considered in children with factors associated with PFT abnormalities.
