ABSTRACT
INTRODUCTION: Acute bronchiolitis is the main cause of hospitalization in children under 2 years of age, with a regular seasonality, mostly due to the respiratory syncytial virus. OBJECTIVES: To describe the epidemiology of bronchiolitis hospitalizations in our center in the last 12 years, and analyze the changes in clinical characteristics, microbiology, and adverse outcomes during the SARS-CoV-2 pandemic. METHODS: Observational study including patients admitted for bronchiolitis between April 2010 and December 2021 in a Spanish tertiary paediatric hospital. Relevant demographic, clinical, microbiological, and adverse outcome variables were collected in an anonymized database. The pandemic period (April 2020 to December 2021) was compared to 2010-2015 seasons using appropriate statistical tests. RESULTS: There were 2138 bronchiolitis admissions, with a mean of 195.6 per year between 2010 and 2019 and a 2-4-month peak between November and March. In the expected season of 2020, there was a 94.4% reduction of bronchiolitis hospitalizations, with only 11 cases admitted in the first year of the pandemic. Bronchiolitis cases increased from the summer of 2021 during a 6-month long peak, reaching a total of 171 cases. Length of stay was significantly shorter during the pandemic, but no differences were found in clinical and microbiological characteristics or other adverse outcomes. CONCLUSIONS: The SARS-CoV-2 pandemic has modified the seasonality of bronchiolitis hospitalizations, with a dramatic decrease in cases during the expected season of 2020-2021, and an extemporaneous summer-autumn peak in 2021 with longer duration but similar patient characteristics and risk factors.

BACKGROUND: Cutaneous manifestations have been included in COVID-19 patients' clinical spectrum. Our objective was to determine the association between skin lesions in children and SARS-CoV2 infection, analyzing others possible infectious/autoimmune etiologies. MATERIAL AND METHODS: Observational, multicenter, cross-sectional study, about children with skin manifestations from April to May 2020. The diagnosis of SARS-CoV2 was performed by PCR in nasopharyngeal exudate and/or presence of antibodies by serology. RESULTS: Sixty-two children were included, 9 (14.5%) presented positive antibodies to SARS-CoV-2, with no positive PCR to SARS-Cov-2 in those patients in whom it was made. Patients with positive serology to SARS-CoV-2 presented chilblains and/or vesicular-bullous skin lesions more frequently (66.7% vs. 24.5%, p = 0.019). Generalized, urticarial and maculopapular rash was more common in patients with negative antibodies (37.7 vs. 0%, p = 0.047), others pathogens were isolated in 41.5% of these patients. There were no significant differences in the positivity for autoantibodies between both groups. CONCLUSION: In our study, the presence of chilblains-like and/or vesicular lesions were significantly related to SARS-CoV2 previous contact.
INTRODUCCIÓN: Las manifestaciones cutáneas se han incluido en el espectro clínico de los pacientes con COVID-19. Nuestro objetivo fue determinar la asociación entre las lesiones cutáneas observadas en niños durante la primera ola de la pandemia y la infección por SARS-CoV-2, analizando otras posibles etiologías infecciosas o autoinmunes. MATERIAL Y MÉTODOS: Estudio observacional, multicéntrico, de corte transversal, desarrollado en niños con manifestaciones cutáneas desde abril hasta mayo de 2020. La determinación de SARS-CoV-2 se realizó mediante PCR en exudado nasofaríngeo y/o serología. RESULTADOS: Se seleccionó a 62 niños; 9 (14,5%) presentaron serología positiva para SARS-CoV-2, siendo la PCR negativa en todos los casos en los que se realizó. Los pacientes con serología positiva para SARS-CoV-2 presentaron con más frecuencia lesiones pernióticas y/o vesiculosas (66,7 vs. 24,5%; p = 0,019). El exantema generalizado, urticarial y maculopapuloso fue más habitual en el grupo de pacientes con serología negativa (37,7 vs. 0%; p = 0,047); se aislaron otros patógenos en el 41,5%. No hubo diferencias significativas en cuanto a la positividad de autoanticuerpos entre ambos grupos. CONCLUSIÓN: En nuestro estudio, las lesiones de tipo perniosis o vesiculosas se relacionaron significativamente con el contacto previo con SARS-CoV-2.

Introduction: COVID-19 has a less severe course in children. In April 2020, some children presented with signs of multisystem inflammation with clinical signs overlapping with Kawasaki disease (KD), most of them requiring admission to the pediatric intensive care unit (PICU). This study aimed to describe the prevalence and clinical characteristics of KD SARS-CoV-2 confirmed and negative patients during the pandemic in Spain. Material and Methods: Medical data of KD patients from January 1, 2018 until May 30, 2020 was collected from the KAWA-RACE study group. We compared the KD cases diagnosed during the COVID-19 period (March 1-May 30, 2020) that were either SARS-CoV-2 confirmed (CoV+) or negative (CoV-) to those from the same period during 2018 and 2019 (PreCoV). Results: One hundred and twenty-four cases were collected. There was a significant increase in cases and PICU admissions in 2020 (P-trend = 0.001 and 0.0004, respectively). CoV+ patients were significantly older (7.5 vs. 2.5 yr) and mainly non-Caucasian (64 vs. 29%), had incomplete KD presentation (73 vs. 32%), lower leucocyte (9.5 vs. 15.5 × 109) and platelet count (174 vs. 423 × 109/L), higher inflammatory markers (C-Reactive Protein 18.5vs. 10.9 mg/dl) and terminal segment of the natriuretic atrial peptide (4,766 vs. 505 pg/ml), less aneurysm development (3.8 vs. 11.1%), and more myocardial dysfunction (30.8 vs. 1.6%) than PreCoV patients. Respiratory symptoms were not increased during the COVID-19 period. Conclusion: The KD CoV+ patients mostly meet pediatric inflammatory multisystem syndrome temporally associated with COVID-19/multisystem inflammatory syndrome in children criteria. Whether this is a novel entity or the same disease on different ends of the spectrum is yet to be clarified.
ABSTRACT
BACKGROUND: The role of SARS-CoV-2 as the cause of chilblains in children remains a matter of debate but it is important to elucidate it for patient isolation and contact tracing. We sought to define the etiology, clinical presentation, time course, and outcomes of children presenting to the emergency department (ED) with cutaneous manifestations shortly after the first pandemic peak of COVID-19 in Spain. METHODS: A prospective, observational study in children <15 years of age evaluated for skin lesions in the EDs of three pediatric hospitals. Children underwent a comprehensive work-up including tests for SARS-CoV-2 antibodies and polymerase chain reaction (PCR), and serology and PCR tests for other viruses and bacteria. A 1 month follow-up visit was conducted. RESULTS: From April 14 through May 8, 2020, we enrolled 62 children. Of those, 34 had acro-ischemic skin lesions and 28 had a variety of skin rashes. Overall, 40% of children had mild systemic symptoms. Children with chilblains were older, had pain more frequently and a more prolonged duration of skin lesions, while those with non-specific rashes had fever more frequently. Lesions were resolved in 75% of children at follow up. Five patients demonstrated SARS-CoV-2 antibodies, and none tested positive with PCR. Three additional patients tested positive with PCR for rhinovirus, Mycoplasma pneumoniae and Chlamydia pneumoniae. CONCLUSIONS: The number of ED visits for chilblains, which are rare in pediatrics, was high soon after the first peak of COVID-19 in Spain. The disease course was self-limited, outcomes were favorable, and the possibility of viral transmission was negligible as all patients tested negative for SARS-CoV-2 by PCR.

A new paediatric multisystem inflammatory syndrome, linked to SARS-CoV-2, has been described. The clinical picture is variable and is associated with an active or recent infection due to SARS-CoV-2. A review of the existing literature by a multidisciplinary group of paediatric specialists is presented in this document. Later, they make recommendations on the stabilisation, diagnosis, and treatment of this syndrome.
