The Predictors of Pneumonia in Children with COVID-19

The purpose of this study was to evaluate the relationship between the presence of pneumonia and blood parameters in casesof Coronavirus disease (COVID-19) and to examine their predictive characteristics in terms of pneumonia. We reviewed the filerecords of 151 pediatric patients with a diagnosis of COVID-19 confirmed by the real time-reverse transcription polymerase chainreaction test in nasopharyngeal swabs. The patients were divided into two groups based on direct chest X-ray and computedtomography results in [Group 1 (n:41), with pneumonia findings, and Group 2 (n:110), with no pneumonia findings]. The groups’demographic data, clinical and laboratory findings were compared. Pulmonary involvement was determined in 41 (27.1%) ofthe 151 patients. The [body mass index (BMI) Z-score], red blood cell distribution width (RDW), mean platelet volume (MPV),neutrophil lymphocyte ratio, passive leg raise, and D-dimer levels were significantly higher in patients with pneumonia than thosewithout pneumonia in our study. Based on multivariate logistic regression analysis, BMI Z-score, MPV, and RDW were found tobe independent risk factors of pneumonia in patients. The current study showed higher levels of blood parameters in patients withcoronavirus disease 2019 (COVID -19) presenting with pneumonia than those without pneumonia. We suggest that BMI-Z scoreand MPV value may assist in predicting pulmonary involvement in patients with COVID-19.
