Although the underlying disease is associated with a severe course in adults and laboratory abnormalities have been widely reported, there are not sufficient data on the clinical course of coronavirus disease 2019 (COVID‐19) in children with pre‐existing comorbid conditions and on laboratory findings. We aimed to describe the independent risk factors for estimating the severity of the COVID‐19 in children. All children between 1 month and 18 years old who were hospitalized during the period of March 11–December 31, 2020, resulting from COVID‐19 were included in the study. Patients were categorized into mild (group 1) and moderate + severe/critically (group 2) severity based on the criteria. Demographic characteristics, comorbidities, and laboratory variables between the two groups were compared. A total of 292 children confirmed to have COVID‐19 infection were included in the study. The most common associated diseases were obesity (5.1%) and asthma bronchiale (4.1%). We observed that disease progressed more severely in patients with underlying diseases, especially obesity and asthma bronchiale (for patients with obesity odds ratio [OR] 9.1, 95% confidence interval [CI] 1.92–43.28, p = 0.005 and for patients with asthma bronchiale OR 4.1, 95% CI 1.04–16.80, p = 0.044). In group 2 patients, presence of lymphopenia and hypoalbuminemia, and also an elevation in serum levels of C‐reactive protein, procalcitonin, and uric acid were detected and these results were statistically significant ( p values; p < 0.001, p = 0.046, p = 0.006, p = 0.045, p < 0.001, respectively). The strongest predictor of moderate‐severe COVID‐19 infections in the children was uric acid, with an odds ratio of 1.6 (95% CI 1.14–2.13, p = 0.005) and lymphocytes with an odds ratio of 0.7 (95% CI 0.55–0.88, p = 0.003). Although children are less susceptible to COVID‐19, the pre‐existing comorbid condition can predispose to severe disease. In addition, lymphopenia and high uric acid are indicators that COVID‐19 infection may progress more severely.
Background The study aimed to evaluate the distribution of circulating respiratory viral pathogens other than SARS-CoV-2 during the first year of the coronavirus disease–2019 (COVID-19) pandemic with especially focusing on the effects of the national-based mitigation strategies. Methods This single-center study was conducted between March 11, 2020-March 11, 2021. All children who were tested by polymerase chain reaction (PCR) on nasopharyngeal swabs for SARS-CoV-2 and other common respiratory viral pathogens were included in the study. Results A total of 995 children with suspected COVID-19 admitted to the study center. Of these, 513 patients who were tested by PCR for both SARS-CoV-2 and common respiratory viral pathogens were included in the final analysis. Two hundred ninety-five patients were (57.5%) male. The median age was 3 years of age (27 days-17 years). A total of 321 viral pathogens identified in 310 (n:310/513, 60.4%) patients, and 11 of them (n:11/310, 3.5%) had co-detection with more than one virus. The most common detected virus was rhinovirus (n:156/513, 30.4%), and SARS-CoV-2 (n:122/513, 23.8%) followed by RSV (n:18/513, 3.5%). The influenza virus was detected in two patients (0.4%). A total of 193 patients were negative for both SARS-CoV-2 and other pathogens. Conclusion There is a decline in the frequency of all viral pathogens like SARS-CoV-2 in correlation with the national-based mitigation strategies against COVID-19 during the pandemic.
Objectives This descriptive study aimed to compare the clinical and laboratory features of the children with the multisystem inflammatory syndrome in children (MIS-C), requiring pediatric intensive care unit (PICU), admission with the MIS-C patients who did not require PICU admission. Patients and methods This study was conducted between March 2020 and February 2021 at the University of Health Sciences Dr. Behçet Uz Children’s Hospital, a referral center for pediatric infectious diseases in the Aegean Region of Turkey. All hospitalized patients aged 18 years old or less with MIS-C according to the definition of the universal guidelines were included in the study. Data of the patients with the diagnosis of MIS-C were recorded and collected from the electronic medical records of the hospital. The data included demographic characteristics, presenting signs and symptoms, laboratory findings and clinical data. Results A total of 58 patients with MIS-C were included in this study. Thirty-eight (65.5%) patients were male. The median age was 6 years (2 months–16 years). The patients admitted to PICU were 15 (25.9%). The rate of pulmonary involvement was 81.3% (n = 13) in the PICU group. The median procalcitonin, C-reactive protein, erythrocyte sedimentation rate, D-Dimer and ferritin values were significantly higher in the PICU group compared to non-PICU group (p < 0.001, p = 0.02, p < 0.001, p = 0.006 and p = 0.031). Conclusions Besides the depressing cardiac functions reported before, the pulmonary involvement and signs of shock are important factors for PICU admission in children with MIS-C.
Severe acute respiratory syndrome coronavirus 2 is reappearing with an increasing number of variants every day; this study aimed to determine the effect of B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), and B.1.617.2 (Delta) variants on hospitalization rates. This single-center study was conducted at the University of Health Sciences Dr. Behçet Uz Children's Hospital from March 11 to August 27, 2021. Variant analyses of symptomatic patients admitted to the hospital who were found to be positive for COVID 19 PCR was performed. Out of 680 cases, 329 (48.4%) were B.1.1.7 variant, 17 (2.5%) were B.1.351/P.1 variant, and 165 (24.2%) were B.1.617.2 variant. One hundred and sixty-nine (24.9%) case variant analysis results were negative. The hospitalization rate of patients with the B.1.617.2 variant was 19.4%, the B.1.351/P.1 variant was 18%, the B.1.1.7 variant was 9.4%, and the negative variant was 10.1%. The B.1.617.2 (Delta) variant, which has become widespread all over the world recently, increases the rate of hospitalization in children.
