Kidney complications associated with COVID-19 infection and vaccination in children and adolescents: a brief review   (11 times)
Hee Sun Baek, Min Hyun Cho
Clin Exp Pediatr. 2023;66(10):424-431.   Published online June 28, 2023
Several observational studies have shown that acute kidney injury affects up to 46% of children and adolescents who develop severe postinflammatory responses, such as multisystem inflammatory syndrome in childhood, due to coronavirus disease 2019 (COVID-19). Although causality has not been established, some cases of glomerulopathy or nephrotic syndrome occurring after COVID-19 infection or vaccination have been reported. Therefore, kidney complications associated with these conditions in children and adolescents warrant attention.

Protective effect of recombinant interleukin-10 on newborn rat lungs exposed to short-term sublethal hyperoxia   (9 times)
Hyeon-Soo Lee, Young-Joon Ryu, Min-Jae Lee
Clin Exp Pediatr. 2024;67(10):540-549.   Published online September 27, 2024
Lung injury is generated from the early stage of hyperoxia through the biologic effects of cell death and inflammatory response, which eventually leads to evolution of bronchopul-monary dysplasia. Therefore, a protective measure against hyperoxia-induced lung injury is needed. The present study observed that anti-inflammatory cytokine, interleukin-10 had protective effects on newborn rat lungs from injury induced at the early stage of hyperoxia, by preventing cell death and down-regulating inflammatory response.

COVID-19 in immunocompromised children and adolescents   (7 times)
Byung Ok Kwak, Byung Wook Eun
Clin Exp Pediatr. 2023;66(5):182-189.   Published online April 18, 2023
Most immunocompromised children and adolescents are not at increased risk of developing severe coronavirus disease 2019 (COVID-19). COVID-19 outcomes for low- or medium-risk immunocompromised children are favorable, while more serious illness reportedly occurs in high-risk immunocompromised children by underlying disease, its treatments, and other factors. Therefore, the early detection and timely management of severe COVID-19 and treatment of underlying disease are important. Hospitalization and COVID-19 vaccination should be carefully considered.
