Streptococcus pyogenes infections in Spanish children before and after the COVID pandemic. Coming back to the previous incidence

Introduction Group A Streptococcus (GAS) causes mild diseases, and unfrequently invasive infections (iGAS). Following the December 2022 alert from the United Kingdom regarding the unusual increase in GAS and iGAS infections, we analyzed the incidence of GAS infections in 2018–2022 in our hospital. Methods We conducted a retrospective study of patients seen in a pediatric emergency department (ED) diagnosed with streptococcal pharyngitis and scarlet fever and patients admitted for iGAS during last 5 years. Results The incidence of GAS infections was 6.43 and 12.38/1000 ED visits in 2018 and 2019, respectively. During the COVID-19 pandemic the figures were 5.33 and 2.14/1000 ED visits in 2020 and 2021, respectively, and increased to 10.2/1000 ED visits in 2022. The differences observed were not statistically significant (p=0.352). Conclusions In our series, as in other countries, GAS infections decreased during the COVID-19 pandemic, and mild and severe cases increased considerably in 2022, but did not reach similar levels to those detected in other countries. Resumen Introducción Streptococcus del grupo A (GAS) causa infecciones leves y ocasionalmente invasivas (iGAS). Tras la alerta publicada en diciembre de 2022 en el Reino Unido respecto al aumento de infecciones por GAS leves e iGAS, analizamos la incidencia de estas infecciones en 2018-2022 en nuestro hospital. Métodos Realizamos un estudio retrospectivo de los niños atendidos en urgencias pediátricas (UP) diagnosticados de faringitis estreptocócica y escarlatina y los ingresados por iGAS durante 5 años. Resultados La incidencia de infecciones por GAS fue de 6,43 y de 12,38/1.000 visitas a UP en 2018 y 2019, respectivamente. Durante la pandemia fue de 5,33 y de 2,14/1.000 visitas en 2020 y 2021, respectivamente, y aumentó a 10,2/1.000 visitas en 2022. Estas diferencias no fueron estadísticamente significativas (p=0,352). Discusión En nuestra serie, al igual que en otros países, las infecciones por GAS disminuyeron durante la pandemia de COVID-19, pero en 2022 aumentaron considerablemente los casos leves y graves, sin alcanzar cifras similares a las detectadas en otros países.

Pediatric Burns Debridement Under Sedoanalgesia During the COVID-19 Pandemic: A Cost-Effective Alternative.

Early debridement of childhood burns under sedoanalgesia in the emergency department (ED) may help to reduce the need of surgery and delay in treatment. We performed a retrospective study in burned children who underwent debridement in the ED under sedoanalgesia between March 2020 and December 2020 (COVID group), and were compared with the same months in 2019 (control group). Demographics, burns features, admission rate, and estimated costs associated were collected. A total of 733 children presented at the ED with burns (302 COVID group and 431 control group) without significant differences in burn features between them. Admission rate was significantly lower in COVID group (9.4% vs 19.4%; P < .001), as was the total associated cost for each group ($101 585 vs $209 656; P < .001). The use of sedoanalgesia for the early treatment of pediatric burns in the ED during COVID-19 pandemic is a cost-effective alternative that has reduced the need for hospital admission and associated costs.

Comparative study shows that 1 in 7 Spanish children with COVID-19 symptoms were still experiencing issues after 12 weeks.

AIM: We investigated prolonged symptoms in children after COVID-19, including the clinical characteristics and risk factors. METHODS: This multicentre retrospective study focused on 451 children under 18 years old who were diagnosed with symptomatic COVID-19 between 14 March and 31 December 2020. Persistent symptoms were analysed with a telephone questionnaire by the attending physicians from 1 August to 30 September 2021. A control group of 98 with no history of COVID-19, who were treated for other reasons, was also included. RESULTS: Most (82.0%) of the cases had mild infections that required outpatient care and 5.1% were admitted to the paediatric intensive care unit (PICU). We found that 18.4% had symptoms that lasted 4-12 weeks. There were also 14.6% who were symptomatic for longer than 12 weeks and the odds risks were higher for children aged 5 years or more (OR 3.0), hospitalised (OR 3.9), admitted to the PICU (OR 4.3) and with relatives who were symptomatic for 12 weeks or more (OR 2.8). The controls had similar percentages of prolonged symptoms, despite having no history of COVID-19, especially those who were older than 5 years. CONCLUSION: This study confirmed that a worrying percentage of children had prolonged symptoms after COVID-19.

Clinical spectrum of COVID-19 and risk factors associated with severity in Spanish children.

We aimed to identify the spectrum of disease in children with COVID-19, and the risk factors for admission in paediatric intensive care units (PICUs). We conducted a multicentre, prospective study of children with SARS-CoV-2 infection in 76 Spanish hospitals. We included children with COVID-19 or multi-inflammatory syndrome (MIS-C) younger than 18 years old, attended during the first year of the pandemic. We enrolled 1200 children. A total of 666 (55.5%) were hospitalised, and 123 (18.4%) required admission to PICU. Most frequent major clinical syndromes in the cohort were mild syndrome (including upper respiratory tract infection and flu-like syndrome, skin or mucosae problems and asymptomatic), 44.8%; bronchopulmonary syndrome (including pneumonia, bronchitis and asthma flare), 18.5%; fever without a source, 16.2%; MIS-C, 10.6%; and gastrointestinal syndrome, 10%. In hospitalised children, the proportions were 28.5%, 25.7%, 16.5%, 19.1% and 10.2%, respectively. Risk factors associated with PICU admission were age in months (OR: 1.007; 95% CI 1.004 to 1.01), MIS-C (OR: 14.4, 95% CI 8.9 to 23.8), chronic cardiac disease (OR: 4.8, 95% CI 1.8 to 13), asthma or recurrent wheezing (OR: 2.5, 95% CI 1.2 to 5.2) and after excluding MIS-C patients, moderate/severe liver disease (OR: 8.6, 95% CI 1.6 to 47.6). However, asthmatic children were admitted into the PICU due to MIS-C or pneumonia, not due to asthma flare.Conclusion: Hospitalised children with COVID-19 usually present as one of five major clinical phenotypes of decreasing severity. Risk factors for PICU include MIS-C, elevation of inflammation biomarkers, asthma, moderate or severe liver disease and cardiac disease. What is Known: • All studies suggest that children are less susceptible to serious SARS-CoV-2 infection when compared to adults. Most studies describe symptoms at presentation. However, it remains unclear how these symptoms group together into clinically identifiable syndromes and the severity associated with them. What is New: • We have gathered the primary diagnoses into five major syndromes of decreasing severity: MIS-C, bronchopulmonary syndrome, gastrointestinal syndrome, fever without a source and mild syndrome. Classification of the children in one of the syndromes is unique and helps to assess the risk of critical illness and to define the spectrum of the disease instead of just describing symptoms and signs.

Complicated Acute Appendicitis during COVID-19 Pandemic: The Hidden Epidemic in Children.

INTRODUCTION: Since home confinement for novel coronavirus disease 2019 (COVID-19) pandemic began, pediatric visits to the emergency department (ED) have decreased, including consultation for abdominal pain. Our aim is to investigate the incidence of complicated acute appendicitis (AA; peritonitis or appendicular mass) during confinement for COVID-19 pandemic and to compare it with the previous 5 years. MATERIALS AND METHODS: A retrospective study was performed in children with AA who underwent surgery between March 9 and April 13 from 2015 to 2020; patients were divided into six groups according to the year of surgery. We analyzed demographic variables, time from onset of symptoms, mean hospital stay, cumulative incidence, and incidence rate of complicated appendicitis. RESULTS: A total of 168 patients were included with no differences in the number of patients, gender, and age between groups. Patients in 2020 (COVID-19 group) presented longer symptom progression time (46.8 hours; p = 0.046), higher rate of complicated appendicitis (48.4%; p = 0.004), longer mean hospital stay (4.9 days; p < 0.001), increased cumulative incidence (8.27 cases per 100,000 children per 0.1 years; p < 0.001), and increased incidence rate of complicated appendicitis (83 cases per 100,000 children; p < 0.001) when compared with other groups. CONCLUSION: Delayed ED visit of children with AA during home confinement lead to an increased rate of complicated appendicitis. It is crucial to make parents aware of the importance of early diagnosis and treatment of abdominal pain.
