Clinical and Nutritional Aspects and Outcomes of Covid-19 in Cancer and Non-Cancer Pediatric Patients

The SARS-CoV-2 virus has been the subject of study by several researchers worldwide since 2020; however, there are points to be clarified. This study aimed to analyze the clinical and nutritional aspects of hospitalized cancer and non-cancer pediatric patients and the association with COVID-19 outcomes. This is a cohort study of hospitalized children and adolescents with a laboratory diagnosis of COVID-19. Patients were assessed according to the presence or absence of previous oncological diseases. Sociodemographic, clinical and nutritional data were investigated during the course of the infection. Outcomes included Intensive Care Unit (ICU) admission, longer length of stay (14 days), criticality, and death. Oncological disease was found in 16 (19.3%) patients, most of whom had B-type acute lymphoid leukemia. In Poisson regression, adjusted for age and comorbidity, an association was found between oncological disease and length of stay ≥14 days (RR 4.30; 95% CI 1.46 - 15.6; <i>p</i> = 0.013), COVID-19 criticality (RR 3.82; 95% CI 1.66 - 30.9; <i>p</i> = 0.010) and death (RR 3.42; 95% CI 0.94 - 9.96; <i>p</i> = 0.035). The research revealed that cancer patients had longer hospital stays, were more likely to have the severe form of COVID-19, and had a 3.42 times greater risk of dying.
