ABSTRACT
BACKGROUND: The number of pediatric cases of infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant has increased. Here, we describe the clinical characteristics of children in a tertiary children's medical center in Shanghai. METHODS: A total of 676 pediatric coronavirus disease 2019 (COVID-19) cases caused by the Omicron variant who were admitted to the Shanghai Children's Medical Center from March 28 to April 30, 2022 were enrolled in this single-center, prospective, observational real-world study. Patient demographics and clinical characteristics, especially COVID-19 vaccine status, were assessed. RESULTS: Children of all ages appeared susceptible to the SARS-CoV-2 Omicron variant, with no significant difference between sexes. A high SARS-CoV-2 viral load upon admission was associated with leukocytopenia, neutropenia, and thrombocytopenia (P = 0.003, P = 0.021, and P = 0.017, respectively) but not with physical symptoms or radiographic chest abnormalities. Univariable linear regression models indicated that comorbidities (P = 0.001) were associated with a longer time until viral clearance, and increasing age (P < 0.001) and two doses of COVID-19 vaccine (P = 0.001) were associated with a shorter time to viral clearance. Multivariable analysis revealed an independent effect of comorbidities (P < 0.001) and age (P = 0.003). The interaction effect between age and comorbidity showed that the negative association between age and time to virus clearance remained significant only in patients without underlying diseases (P < 0.001). CONCLUSION: This study describes the clinical characteristics of children infected with the Omicron variant of SARS-CoV-2 and calls for additional studies to evaluate the effectiveness and safety of vaccination against COVID-19 in children.
ABSTRACT
BACKGROUND AND OBJECTIVES: During the coronavirus disease 2019 outbreak, the treatment of families with children on long-term KRT is challenging. This study was conducted to identify the current difficulties, worries regarding the next 2 months, and mental distress experienced by families with children on long-term KRT during the coronavirus disease 2019 outbreak and to deliver possible management approaches to ensure uninterrupted treatment for children on long-term KRT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A multicenter online survey was conducted between February 10 and 15, 2020, among the families with children on long-term KRT from five major pediatric dialysis centers in mainland China. The primary caregivers of children currently on long-term KRT were eligible and included. Demographic information, severe acute respiratory syndrome coronavirus 2 infection status, current difficulties, and worries regarding the next 2 months were surveyed using a self-developed questionnaire. The Patient Health Questionnaire-9 and the General Anxiety Disorder Scale-7 were used to screen for depressive symptoms and anxiety, respectively. RESULTS: Among the children in the 220 families included in data analysis, 113 (51%) children were on dialysis, and the other 107 (49%) had kidney transplants. No families reported confirmed or suspected cases of coronavirus disease 2019. Overall, 135 (61%) and 173 (79%) caregivers reported having difficulties now and having worries regarding the next 2 months, respectively. Dialysis supply shortage (dialysis group) and hard to have blood tests (kidney transplantation group) were most commonly reported. A total of 29 (13%) caregivers had depressive symptoms, and 24 (11%) had anxiety. After the survey, we offered online and offline interventions to address their problems. At the time of the submission of this paper, no treatment interruption had been reported. CONCLUSIONS: The coronavirus disease 2019 outbreak has had physical, mental, logistical, and financial effects on families with children on long-term KRT.
