COVID-19 Infection In Children Research Articles

Respiratory sequelae after COVID-19 infection in Thai healthy children.

The long-term respiratory sequelae of COVID-19 infection in children remain poorly understood and may differ across countries. This study aims to investigate the respiratory sequelae, including residual respiratory symptoms and pulmonary function in Thai children. The secondary aim is to identify factors associated with the respiratory sequelae. This is an observational study involving 56 healthy children, aged between 7 and 18 years, who were diagnosed with COVID-19 infection from July 2021 to February 2023. Clinical data relating to COVID-19 infection and persistent symptoms after the infection were assessed after the infection up to 6 months. Spirometry was performed to assess pulmonary function. Post-COVID-19 symptoms were identified in 14 patients (25%), with fatigue, cough, and dyspnea being common symptoms (28%-35%). A significant correlation was found between post COVID-19 symptoms and pneumonia (OR = 6.00, 95%CI [1.54,23.33], p = .01). Abnormal pulmonary function was identified in 10 patients (17.8%) with obstructive impairment being the most common. However, there was no significant association between clinical factors and pulmonary function impairment. Prolonged respiratory symptoms and abnormal pulmonary function following COVID-19 infection are not uncommon in children. The post-COVID-19 symptoms are possibly associated with COVID-19 pneumonia.

Cardiac effects of COVID-19 infection in children.

It is known established that the cardiac effects of COVID-19 infection are associated with poor prognosis and high mortality rates in infected patients. The aim of this study was to evaluate the cardiac effects of COVID-19 infection in paediatric patients and identify the correlations between clinical and laboratory data and the degree of cardiac involvement. A retrospective data analysis was conducted on 64 paediatric patients at Gazi University Department of Pediatrics who were treated as inpatients with a diagnosis of COVID-19. Patients were classified as "COVID-19-related cardiac involvement cases" if their electrocardiogram and echocardiogram results indicated a pathology and/or if their laboratory data indicated increased cardiac enzymes. All patients were divided into subgroups based on whether they had cardiac involvement and whether they were diagnosed with multisystem inflammatory syndrome in children. In comparison to patients who did not have cardiac involvement, those with cardiac involvement had significantly higher levels of hs-Troponin T, Pro-BNP, and D-dimer. Patients with multisystem inflammatory syndrome in children had significantly longer PR intervals than those without multisystem inflammatory syndrome in children (p = 0.0001). Patients with multisystem inflammatory syndrome in children had a significantly higher rate of pathological valve insufficiencies (68.1%) than those without multisystem inflammatory syndrome in children (14.2%) (p = 0.001). In our study, the strongest predictive biomarker of cardiac involvement in paediatric patients with COVID-19 infection was determined to be hs-Troponin T. It was observed that pathologic electrocardiogram changes could reflect cardiac involvement in the absence of any other signs. Patients with multisystem inflammatory syndrome in children exhibited significantly greater rates of pathologic echocardiogram findings and myocardial dysfunction than those without multisystem inflammatory syndrome in children. In all patients, pathologic electrocardiogram and echocardiogram findings were found to be strongly associated with the severity of inflammation.

Association Between the Level of Vitamin D and COVID-19 Infection in Children and Adolescents: A Systematic Review.

The COVID-19 pandemic has exerted a notable impact on worldwide health across diverse age groups. Although children and adolescents were initially considered less vulnerable, they have also shown susceptibility to the virus, emphasizing the importance of understanding associated risk factors. Epidemiological data reveal an increasing number of COVID-19 cases in this age group. The aim is to conduct a systematic assessment of the association between the level of vitamin D and COVID-19 infection in children and adolescents following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was performed across various databases up to October 7, 2023. Studies assessing laboratory-confirmed COVID-19 patients, the level of 25-hydroxyvitamin D in serum, and clinical outcomes were encompassed. Quality assessment was performed using the Newcastle-Ottawa Scale. Thirteen studies, conducted across six countries and involving 1,071 pediatric patients, were included. Vitamin D deficiency was prevalent among children and adolescents with COVID-19. Some studies suggested that vitamin D deficiency significantly increased the risk of COVID-19 infection and was linked to disease progression. Furthermore, deficiency in vitamin D demonstrated an association with increased levels of inflammatory markers, reduced lymphocyte counts, and heightened clinical symptoms, including fever and cough. Maintaining adequate vitamin D levels may be a crucial strategy for reducing COVID-19 severity and associated complications in children and adolescents. Nevertheless, there is a requirement for additional high-quality research to establish specific guidelines regarding vitamin D supplementation in this population amid the ongoing COVID-19 pandemic.

Analysis of Clinical and Radiologic Parameters in Children Diagnosed with COVID-19 Infection at Admission and Discharge

Background: Recognizing risk factors for poor prognosis among COVID-19 patients is crucial, especially given the absence of standardized treatments and medications. Objectives: In the present study, our aim was to survey changes in clinical parameters in children diagnosed with COVID-19 infection from admission to discharge. Methods: The present retrospective cross-sectional study focused on children with COVID-19 infection. All demographic data and clinical information of patients were extracted upon admission and at discharge from the hospital. Data analysis utilized the Mann-Whitney U test and Fisher exact test. Multivariable regression modeling was employed to identify factors predicting the probability and duration of hospitalization in ICUs for children with COVID-19. Results: Elevated levels of ESR, CRP, creatinine, and ferritin were found in 51.7%, 67.4%, 69.3%, and 53.6% of patients upon admission. Moreover, 98.2% and 38.3% of patients had high levels of ALP and AST. Platelet (PLT) and neutrophil levels were higher at discharge compared to admission (P < 0.001), while creatinine levels were lower at admission than at discharge (P < 0.001). Patients admitted to ICUs exhibited significantly higher levels of pulse rate (P < 0.001), respiratory rate (P < 0.001), mean corpuscular volume (MCV) (P = 0.01), red cell distribution width (RDW) (P = 0.002), prothrombin time (PT) (P = 0.006), and ESR (P = 0.04). Conclusions: Pulse rate, respiratory rate, MCV, RDW, PT, ESR, and oxygen saturation (SPO2) percentage can be used to predict the severity of COVID-19 disease. However, further studies are needed to determine the prognosis and severity of COVID-19 infection in children.

Proton Pump Inhibitors and Risk of COVID-19 Infection in Children

To evaluate the influence of proton pump inhibitor (PPI) use on COVID-19 susceptibility and severity in children. This retrospective, case-control study included all children ≤21years undergoing COVID-19 polymerase chain reaction testing at a tertiary children's hospital between March 2020 and January 2023. The main exposure was PPI usage. The primary outcome was COVID-19 infection. The secondary outcome was COVID-19 hospitalization. Log-binomial regressions were used to examine associations between PPI use and these outcomes. 116 209 patients age 8.5±6.2years underwent 234 867 COVID-19 tests. Current PPI use was associated with a decreased risk of COVID-19 test positivity compared with PPI nonuse [RR 0.85 (95% CI 0.76, 0.94), P=.002]; however, there was a significant interaction with time of testing, and an effect of PPIs was no longer seen in the final months of the study following lessening of COVID-19 precautions [RR 1.04 (95% CI 0.0.80, 1.36), P=.77]. PPI use was not associated with risk of hospitalization in patients positive for COVID-19 after adjusting for other hospitalization risk factors [RR 0.85 (95% CI 0.64, 1.13), P=.26]. We did not find an association between PPI use and increased COVID-19 susceptibility or severity in this pediatric sample. These results provide reassuring evidence that PPIs may not worsen COVID-19 outcomes in children.

COVID-19 infection in children, adolescents, and young adults with Down syndrome and hematologic malignancies.

Children, adolescents, and young adults (CAYAs) with Down syndrome (DS) and hematologic malignancies are particularly vulnerable to infections and related complications. There are limited data regarding COVID-19 infections in this group. We aimed to understand the clinical course of COVID-19 in this population. This observational study leverages the de-identified clinical and sociodemographic data captured by the Pediatric Oncology COVID-19 Case Report Registry (POCC) regarding CAYAs with cancer and COVID-19. We evaluated CAYAs (≤21years at COVID-19 infection) with hematologic malignancies and COVID-19 reported from April 1, 2020 to May 2, 2023, comparing those with and without DS. Using multivariable logistic regression, we examined rates of hospitalization, intensive care unit (ICU) admission, respiratory support, and changes in cancer-directed therapy. Among 1408 CAYAs with hematologic malignancies, 55 had DS (CAYA-DS). CAYA-DS had higher rates of hospitalization, ICU admission, and respiratory support (p<.001) than CAYAs without DS. Similarly, multivariable analyses found higher odds of hospitalization (odds ratio [OR]=2.8, 95% confidence interval [CI]: 1.5-5.1), ICU admission (OR=4.2, 95% CI: 1.9-9.1), and need for respiratory support (OR=4.2, 95% CI: 2.0-8.8) among CAYA-DS. Modifications to cancer-directed therapy were more common among CAYA-DS when related to neutropenia (p=.001), but not when unrelated to neutropenia (p=.88); CAYA-DS did not have higher odds of changes to cancer-directed therapy (OR=1.20, 95% CI: 0.7-2.1). We identify CAYA-DS with hematologic malignancies as a vulnerable subpopulation at greater risk for severe COVID-19 infection. This can inform conversations with patients and families regarding therapeutic and preventive measures, as well as the risks and benefits of modifying chemotherapy in the setting of COVID-19.

Clinical and Laboratory Profile, Management and Outcome of Pediatric SARS-CoV-2 Infection Admitted at the Philippine General Hospital.

The Philippines has recorded over 470,000 COVID-19 cases in children, with over 1,500 deaths during the same period. Although a Philippine online pediatric COVID-19 registry exists, this only relies on passive surveillance. This study determined the clinical and laboratory profile, risk factors for severe COVID-19, and mortality, management, and outcome of pediatric SARS-CoV-2 patients admitted at the Philippine General Hospital (PGH) from April 2020 to June 2022 to fill in knowledge gaps on the epidemiology of COVID-19 infection in children. This was a retrospective cohort study of pediatric COVID-19 cases admitted at the PGH, a designated COVID referral center during the study period. Demographic and clinical profile, risk factors, comorbidities, laboratory and radiologic findings, management, and outcomes across different disease severity states were gathered by chart review and the data were analyzed using STATA 17. There were 448 pediatric patients admitted and diagnosed with COVID-19 during the study period. Most patients belonged to the 1-5-year age group (25.9%), had no known exposure to a COVID-19 case (65.4%), were mild cases (37.3%%), and did not receive any dose of the COVID-19 vaccine (96.7%). The most common presenting symptoms across all disease categories were fever (44.4%), cough (28.6%), and shortness of breath (26.6%). Multisystem inflammatory syndrome in children (MIS-C) presented with fever (100%) and rash (53.9%). The risk factors for severe disease were the presence of a congenital anomaly lung disease, and elevated procalcitonin. Most patients with MIS-C were previously well with no comorbidities. Laboratory findings which were markedly elevated among severe and critical cases were ESR, CRP, D-dimer, LDH, and IL-6. Ferritin, procalcitonin (PCT) and IL-6 were elevated only in severe to critical COVID-19 cases and remained within normal for the other disease categories. As to treatment, asymptomatic, mild, and moderate cases were given supportive medications (zinc, vitamin D, and vitamin C), while investigational drugs particularly corticosteroids, IVIG, and remdesivir, were used in severe cases.Antibiotics were given to 71.7% of patients at the outset. As to the outcomes, 89% recovered, while 8.9% died. The case fatality rate from COVID-19 infection was at 2.2%. Admitted pediatric COVID-19 cases are generally mild but admission is due to underlying illness or comorbidities. Those with severe to critical cases have underlying comorbidities and had either progression or complications due to COVID disease. D-dimer, LDH, IL-6, ferritin and procalcitonin were elevated among severe and critical cases which can be utilized as inflammatory markers.

Long-term outcomes of COVID-19 infection in children and young people: a systematic review and meta-analysis

Background Children and young people (CYP) may experience prolonged symptoms following COVID-19, commonly termed ‘Long-COVID’. The characteristics of Long-COVID in CYP are unclear, as are the sequalae of acute COVID-19. We aimed to systematically synthesise evidence of the long-term outcomes of COVID-19 in CYP. Methods 13 electronic databases were searched until January 2022. Inclusion criteria: observational studies reporting outcomes occurring four-weeks or more after COVID-19 in children &lt;18 years old. Exclusion criteria: outcomes of Paediatric Inflammatory Multisystem Syndrome. Title, abstract and full text screening were conducted independently by two reviewers. Data extraction and risk of bias assessment was by one reviewer with independent verification. Critical appraisal tools appropriate for study type were employed. Results were narratively synthesised with meta-analysis to generate summary estimates of risk of prolonged symptoms in CYP. Results 94 studies were included in this systematic review. Of these, 66 studies recruited from hospital settings and 8 studies recruited solely from community settings. Over 100 symptoms were reported, the most common being fatigue, headache and cognitive symptoms. Summary estimates of prevalence of prolonged symptoms were higher for hospital samples (31.2%, 95% CI 20.3% to 43.2%) than for community samples (4.6%, 95% CI 3.4% to 5.8). Reported sequalae of COVID-19 in CYP included stroke, type-1 diabetes, Guillan-Barre syndrome, and persistent radiological or blood test abnormalities. Most studies reporting these sequalae were case reports / case series and the quality of evidence in these studies was low. Conclusions Prolonged symptoms following COVID-19 in children are variable and multi-systemic. Rates of prolonged symptoms in community samples are lower than hospital samples. There is currently limited good quality data on other sequalae in CYP. Heterogeneity in methods of diagnosis of COVID-19, symptom classification, assessment method and duration of follow-up made synthesis less secure.

Association Between SARS-CoV-2 Infection and Cardiovascular Disease in Children and Adolescents: A Cross-sectional Study

Background: The 2019 global coronavirus pandemic is triggered by severe acute respiratory syndrome due to corona virus 2 (SARS-CoV-2). This infection can cause myocardial damage, arrhythmias, acute coronary syndrome, and venous thromboembolism. Objectives: The objective of this study is to provide a comprehensive description of the cardiac manifestations observed in children who have been admitted to the pediatric intensive care unit as a result of SARS-CoV-2 infection. Methods: The current prospective cross-sectional study included patients from Minia University Hospital's pediatric intensive care unit (PICU) isolation unit from April 2022 to April 2023. The study comprised 80 patients divided into two groups: Group I included 46 Corona Virus Induced Disease (COVID-19)-positive patients with cardiac complications. Group II consisted of 34 patients with COVID-19 infection but without cardiac complications. Results: The frequency of cardiac complications was 41.3% (33 children) with arrhythmias and 9% (3 children) with SVT by electrocardiography (ECG), whereas 31.3% of children had myocardial dysfunction (EF &lt; 50%, FS &lt; 25%) on echocardiography (ECHO). In comparison, 7.5% had bundle branch block (BBB). Conversely, 1.3% had pancarditis, and 3.8% had first-degree A-V block. Conclusions: More data is needed on COVID-19's cardiovascular effects on children. We found that acute COVID-19 hospitalized children should have cardiac exams and cardiovascular monitoring. COVID-19 infection in children often impairs systolic function, and arrhythmia may arise in COVID-19 individuals.

Pulmonary function in children post -SARS-CoV-2 infection: a systematic review and meta-analysis

ObjectiveThere are some concerns regarding long-term complications of COVID-19 in children. A systematic review and meta-analysis was performed evaluating the respiratory symptoms and pulmonary function, post-SARS-CoV-2 infection.MethodsA systematic search was performed in databases up to 30 March 2023. Studies evaluating respiratory symptoms and pulmonary function after COVID-19 infection in children were selected. The major outcomes were the frequency of respiratory symptoms and the mean of spirometry parameters. A pooled mean with 95% confidence intervals (CIs) was calculated.ResultsA total of 8 articles with 386 patients were included in meta-analysis. Dyspnea, cough, exercise intolerance, and fatigue were the most common symptoms. The meta-mean of forced expiratory volume (FEV1) and forced vital capacity (FVC) was 101.72%, 95% CI= (98.72, 104.73) and 101.31%, 95% CI= (95.44, 107.18) respectively. The meta-mean of FEV1/FVC and Forced expiratory flow at 25 and 75% was 96.16%, 95% CI= (90.47, 101.85) and 105.05%, 95% CI= (101.74, 108.36) respectively. The meta-mean of diffusing capacity for carbon monoxide was 105.30%, 95%CI= (88.12, 122.49). There was no significant difference in spirometry parameters before and after bronchodilator inhalation.ConclusionsDespite some clinical respiratory symptoms, meta-results showed no abnormality in pulmonary function in follow-up of children with SARS-CoV-2 infection. Disease severity and asthma background had not confounded this outcome.

Clinical and epidemiological profiles of pediatric COVID-19 in two private Kenyan hospitals.

COVID-19 infection has attracted global attention with limited published data on the burden in African children. hospital-based longitudinal survey in children with COVID-19 infection, aged 0-18 years admitted between August 2020 and December 2021. The main objective of the study was to describe socio-demographic, clinical and diagnostic manifestations of COVID-19 infection in children. the study enrolled 85 children. Median age was 5•1 years (IQR = 1•3 - 12•4) with equal gender distribution. Under five years were 52•9%. Average length of hospital stay among non-severe cases was three days (IQR=2•0-5•0). No deaths were reported. Fifteen patients (18•7%) were asymptomatic. The most common presenting symptoms were fever (51•8%), vomiting (36•5%), cough (27•1%), diarrhea (20•0%), nasal congestion (14•1%) and fast breathing (12•9%). Two patients presented in shock and features consistent with Multisystemic Inflammatory Syndrome in Childhood (MIS-C). Procalcitonin and C-reactive proteins were elevated in 76•9% and 45•8% respectively. Majority (n=80) had white cell counts within normal range and none had bacterial pathogens isolated from blood (n=63). Liver and Renal function tests were within the normal range in the majority of those tested (n=24 and n=64 respectively). Three of the five patients with elevated platelet count (>500 x109/L) had clinical diagnosis of MIS-C. Eight of 20 patients subjected to imaging had radiological features of bilateral ground glass opacifications while six of nine patients who presented with cardiovascular compromise had mild to moderate ventricular dysfunction on echocardiography. our study suggests that children in the African setting manifest a mild form of the COVID-19 infection with low mortality.

Comparison of Clinic and Demographic Characteristics of Children with Laboratory-Confirmed and Suspected COVID-19 who Admitted to Pediatric Emergency Clinic

Aim: To determine the frequency of COVID-19 infection in children and to compare the parameters of laboratory-confirmed and suspected cases.&#x0D; &#x0D; Material and Methods: Medical records collected with a prospective design of 1300 pediatric patients who applied to COVID-19 triage of pediatric emergency service. Clinic and demographic characteristics of children with laboratory-confirmed and suspected COVID-19 were compared. Nasopharyngeal swab sample was taken from all pediatric patients in accordance with the possible case definition determined by the national Ministry of Health.&#x0D; &#x0D; Results: The COVID-19 test was found positive in 94 (7.2%) children. Of those, 34.5% children had a history of contact, and 31.9% of all cases were asymptomatic. The mean age of children who were positive for COVID-19 was higher than those who were negative (p

Hepatitis –A late manifestation of COVID-19 in pediatric population?

Complete spectrum of covid 19 infection in children as well as its sequaele is still unknown to the world even after two years of ongoing pandemic. Many manifestations of covid 19 have been missed and are yet to be identified. In this study, we aim to hypothesize hepatitis as a probable late manifestation of COVID-19 infection in children. It was a descriptive retrospective study, in which we have included twenty patients who presented with hepatitis in the pediatric department of a secondary level care centre in Sagar from May to July 2021. And we investigated them further to find out the cause of Hepatitis. Among the 20 patients with HEPATITIS, 15 were tested for covid antibody levels, out of them 14 had raised level of SARS-CoV-2 antibody titre. Pediatricians should recognize that the clinical spectrum of COVID-19 in children can be wider than previously described, often with hepatitis as late manifestation of COVID-19 in children, apart from MIS-C.

COVID-19 effects on mental health of children and adolescents with intellectual disabilities in North Kosovo

Background. People with intellectual disabilities (ID) are susceptible to physical, mental and social implications of the COVID-19 pandemic. Aim. Learning the way young individuals with disabilities dealt with the COVID-19 pandemic and how it affected their lives. Materials and Methods. An epidemiological questionnaire including information on the person’s health, mental state, behavior, educational capabilities, and epidemiological and clinical features of the COVID-19 infection was completed by 41 children/young adults and their family members. Results. During the two-year period of the pandemic, we monitored the frequency of COVID-19 infection in children and adolescents with intellectual disorders, children’s mental condition, and the occurrence of post-COVID symptoms. We also discussed the role of society regarding economic stability and support for families with a disabled member. Conclusions. The severity of COVID-19 symptoms was the independent predictor of mental status deterioration. Children and adolescents with ID experienced a greater prevalence of COVID-19 infection as well as post-COVID sequelae.

COVID-19 infection in children with cancer in Armenia: report for the whole pandemic period

Background and aims. Immunocompromised pediatric patients with cancer are more susceptible to experiencing severe COVID-19 infection compared to other children. In a global registry study of childhood cancer with COVID-19, involving 1500 patients, severe of critical infections were detected in 20 % of the cases. The mortality rate of 4 % excelled that of the general pediatric population. Data about the development of COVID-19 complications in children with cancer remains limited and varies across different countries. This study aims to describe the incidence and characteristics of COVID-19 infection in children with cancer in Armenia.Methods. A prospective analysis was conducted on PCR-confirmed cases of COVID-19 infection in children with cancer aged 0–18 years from 2020 to 2022 at the Pediatric Cancer and Blood Disorders Center of Armenia, Yeolyan Hematology Center, the only pediatric hematology/ oncology institution in our country.Results. Between June 2020 and March 2022, we studied 201 children with cancer in Armenia, of whom 35 cases of COVID-19 infection were confirmed. The median age was 8.4, and the male/female ratio was 1.3. Among the COVID-19-positive patients, 15 had acute lymphoblastic leukemia, 5 had lymphomas, 4 patients had neuroblastoma, and 2 each had medulloblastoma, rhabdomyosarcoma and Ewing sarcoma. There were single cases of osteosarcoma, acute myeloid leukemia and malignant triton tumor. Twenty patients (57 %) were asymptomatic, and the rest presented with fever, sore throat, and cough. Among the patients with hematological malignancies, four developed pneumonia, and two of them experienced cancer progression subsequently. Additionally, four patients had pancytopenia/thrombocytopenia, likely due to the infection with the Omicron in the last three months of the mentioned period. Overall, the incidence of COVID-19 complications was 11 %, and mortality was zero.Conclusion. This is the first nationwide report on COVID-19 in children with cancer in Armenia. The findings indicate lower rates of severe infection and mortality among compared to global estimates. Further studies are emerging to explore these differences.

2624. The Usual Suspects: A Retrospective Analysis of Pediatric Respiratory Viral Testing During the Pandemic

Abstract Background Contention measures implemented during the pandemic drastically changed the epidemiology of viral respiratory infections. Some reports have shown a sharp decrease in Emergency department visits for respiratory illnesses in the first months of the pandemic with an increase in Respiratory Syncytial Virus (RSV) and Enterovirus (EV) in subsequent months. The concern caused by COVID-19 during the beginning of the pandemic may have led healthcare professionals to underdiagnose other respiratory viral infections. The aim of this study is to evaluate the behavior of viral infection through the pandemic. Methods A retrospective analysis was conducted to determine temporal changes in respiratory panel use and viral epidemiology in the pediatric ED from 2018 to 2022. Medical records were used to determine ICU admission and mortality in those with a positive respiratory panel. Results During the study period, a total of 10,000 respiratory PCR panels were performed in the pediatric ED. There was a significant increase in mean number of panels performed per year during the pandemic period compared to two years prior (2899 vs 198 panels/year). However, the Positivity rate decreased considerably during the pandemic (38.27% vs. 63.54%). Of the 10,000 panels performed, COVID-19 was identified in in 993 cases (9.93%), while other respiratory viruses were identified in 31.27% of cases. The most prevalent virus identified were EV (n=1411, 14.9%) and RSV (n=483, 5.1%). These viruses also had the highest rate of ICU admission and mortality. Patients that tested positive for COVID-19 had a lower rate of ICU admission compared to those infected by other viruses (RR=0.88; CI95%=0.78-0.99). Additionally, the mortality rate associated with COVID-19 was significantly lower than that of other viruses (RR=0.62; CI95%=0.49-0.79). PCR Panel Positivity Rate and Viral Infections in Pediatrics ED from 2018-2022 PCR viral panel tests performed, positive tests, and viral isolates from 2018 to 2022 Conclusion The pandemic increased the use of PCR testing for respiratory illnesses, providing a better picture of seasonal epidemiology of viral infections. Although COVID-19 infection in children was a major of concern, this report shows that throughout the pandemic other viruses were more prevalent and significantly more severe. This study serves as a reminder than even in times of emerging infections, healthcare professionals shouldn’t forget the usual causes of infection. Disclosures All Authors: No reported disclosures

Do sports protect us from COVID-19? An evaluation of COVID-19 infection, vaccination status, and cardiac examination findings in children who exercise.

The COVID-19 pandemic which has devastated the whole world for the past 3 years affects different patient groups differently. This study aims to evaluate the prevalence, symptoms, and severity of COVID-19 infection, vaccination status, and cardiac pathologies of children who exercise. The records of the children and adolescents who applied to our paediatric cardiology outpatient clinic for preparticipation examinations between 01.01.22 and 31.12.2022 were scanned retrospectively, and information about their COVID-19 history, the severity of infection, symptoms during the infection, at the time of the examination, and vaccination status was obtained. The results were analysed using MS Excel 2016 software. The study consisted of 240 children [82 (34.17%) girls and 158 (65.83%) boys] whose mean age was 12.64 ± 2.64 years, mean weight was 50.03 ± 15.53 kg, mean height was 157 ± 15.09 cm, and mean body mass index was 19.65 ± 3.59. 129 cases had a COVID-19 history, 74 cases had no COVID-19 history, and 37 only had contact but no polymerase chain reaction positivity. 84 cases were mild, 19 were moderate, and 12 were asymptomatic. The most common symptoms were fatigue, malaise, headache, sore throat, and fever. 51 cases (35.15%) were vaccinated against COVID-19. No significant cardiac pathologies were detected in electrocardiography or echocardiography. This study shows that COVID-19 infections in children who exercise are generally mild and self-limiting. Our findings suggest that exercise may have positive effects on immunity.

Echocardiography and laboratory outcomes of COVID-19 in children with a history of Kawasaki disease: a preliminary observation.

Infection with SARS-CoV-2 virus has been associated with cardiovascular sequelae including multisystem inflammatory syndrome (MIS-C) in children. Patients with a prior history of Kawasaki disease, may be more susceptible to changes in echocardiographic or laboratory findings after COVID-19. The objective of this study was to investigate the echocardiographic and laboratory findings in children with a prior history of Kawasaki disease after SARS-CoV-2 infection. In this study, we performed a retrospective chart review of 41 children younger than 18 years old who were diagnosed with COVID-19 from April to August of 2022 and had a prior history KD. We included echocardiography and blood draw data obtained at the last outpatient follow-up at our hospital for KD, and within 4 months of SARS-CoV-2 infection. Echocardiographic data obtained from 82 age-matched and gender matched controls were also included for comparison. We found that COVID-19 resulted in slightly higher RCA Z-scores within the first month after infection (mean ± SE, 1.20 ± 0.18 vs. 0.83 ± 0.18, p = 0.030), although this increase did not result in coronary artery dilatation, defined as a Z-score of at least 2.5. In addition, we found that degree of RCA dilatation after COVID-19 infection was negatively correlated with the change in monocyte percentage (Pearson's correlation coefficient-0.363, p = 0.020). Moreover, RCA Z-score changes were lower in patients who received at least one dose of mRNA COVID-19 vaccine when compared those who did not receive any (mean ± SE, -0.23 ± 0.16 vs. 0.39 ± 0.17, p = 0.031). In this pilot study we found that COVID-19 infection resulted in slightly higher RCA Z-scores in children with a prior history of KD, although not large enough to be classified as coronary aneurysms. While these changes could be the result of measurement imprecision or interobserver variation, further study of the cardiac outcomes of COVID-19 infection in children with a prior history of KD are needed in the future.
