BackgroundChildren usually have an asymptomatic or mild course of SARS-CoV-2 infection, studies in immunocompromised patients have shown a different evolution. The aim of this study was to describe the clinical, laboratory, and radiologic manifestations of pediatric solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) patients testing positive for SARS-CoV-2.MethodsA multicenter retrospective, observational descriptive study was conducted in 3 tertiary hospitals in Madrid (Spain) between March 2020 and December 2022. Consecutive patients aged 0-18 attending the corresponding pediatric emergency departments with a positive result in the real-time polymerase chain reaction test or antigenic test to detect SARS-CoV-2 in the nasopharyngeal sample were included.ResultsA total of 31 children were included in the study. Sixteen (51.6%) were patients with HSCT and 15 (48.3) were patients with SOT. The median time from transplantation to COVID-19 was 1.2 years (IQR:0.5-5.1). The SOT cohort included liver (n = 4, 12.9%), kidney (n = 4, 12.9%), heart (n = 3, 9.7%), multivisceral (n = 3, 9.7%), and lung (n = 1, 3.2%). Of the 31 patients, only one was asymptomatic. The most common symptom on presentation was fever (76.7%). Abnormalities were seen on chest X-ray in 8 (66.6%) of the 12 patients. There was no significant difference in clinical manifestations, lymphopenia and radiological findings regardless of the type of transplantation or immunosuppression status. Thirteen patients (41.9%) were hospitalized. There were no patient deaths.ConclusionsIn our study, we found that the clinical course and outcome of SOT and HSCT pediatric patients with COVID-19 were generally favorable.Copyright © 2023.
