Abstract
BackgroundA pandemic caused by SARS-CoV-2 infection (COVID-19) has rapidly spread across the globe. Although many articles have established the clinical characteristics of adult COVID-19 patients so far, limited data are available for children. The aim of this study was to reveal the clinical features, laboratory findings and nucleic acid test results of ten pediatric cases. MethodsIn this retrospective single-center cohort study, pediatric cases with COVID-19 infection were consecutively enrolled in one hospital in Huangshi, China from January 1 to March 11, 2020. ResultsA total of 10 children with COVID-19 were recruited. Of them, four were the asymptomatic type, one was the mild type, and five were the moderate type (including two subclinical ones). All patients were from family clusters. Only fever, nasal discharge and nasal congestion were observed. Lymphopenia and leukopenia were uncommon in our sample but elevated levels of lactate dehydrogenase (LDH) and alpha-hydroxybutyrate dehydrogenase (α-HBDH) were observed frequently. Of these laboratory test variables, no statistical difference was identified between asymptomatic and symptomatic patients. Abnormalities in radiological data were detected in five patients, and representative findings of chest CT images were patchy shadows and ground-glass opacities. There were two cases whose oropharyngeal nucleic acid tests reversed to positive after one negative result, and two patients whose oropharyngeal swabs tested negative but rectal swabs showed positive. ConclusionsClinical symptoms were mild in children with COVID-19. Increased levels of LDH and α-HBDH were potential clinical biomarkers for pediatric cases. More attention should be paid to the SARS-CoV-2 viral assessment of rectal swabs before patients are discharged.
