Clinical, laboratory and imaging characteristics, and outcomes of hospitalized children with suspected COVID-19 infection: A report from Isfahan-Iran

The aim of this study was to evaluate the clinical, laboratory and imaging characteristics, and outcomes of hospitalized children with suspected COVID‑19 infection in Isfahan.

In this cross‑sectional study, all children aged<15years, who hospitalized as suspected case of COVID‑19 were enrolled. During this study, all demographic, clinical, laboratory, and imaging characteristics as well as follow‑up data and outcomes of the hospitalized children were recorded by pediatric residents using a questionnaire. The findings of studied populations in the two groups of definite/or suspected and negative COVID‑19 patients were compared.

During 6 months’ period, 137 children with suspected COVID‑19 infection were evaluated. Mean age of studied population was 4.3 (0.38) years. The most common symptoms in order were fever, cough, dyspnea and diarrhea. The most common computed tomography scan findings were bilateral ground glass and subpleural involvements. The rate of mortality was 7.3%. COVID‑19 polymerase chain reaction test was positive in 22% of the patients. Based on the specialist’s diagnosis, 30/25 patients were definite/or suspected to COVID‑19 and reminder (79) were negative. O2 saturation <90%, was significantly higher in children with definite/or suspected diagnosis for COVID‑19 (46.7% vs. 22.4%, P < 0.05). Dyspnea and shivering were significantly higher in children with definite/or suspected diagnosis for COVID‑19 than those negative for COVID‑19(P < 0.05).Mean duration of hospitalization was significantly associated with level of lactate dehydrogenase (P < 0.05).

The clinical, laboratory, and imaging findings of our studied population were similar to other studies, but outcome was not similar which may be due to our studied population (inpatients cases). It is suggested that a better understanding of the infection in children may give important insights into disease pathogenesis, health‑care practices, and public health policies.
