Abstract

Introduction: In youths with type 1 diabetes (T1D), diabetic ketoacidosis (DKA) at onset increased during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. In adults, diabetes was identified as risk factor for severe symptoms and hospitalization with the coronavirus disease-2019 (COVID-19) Objectives: To investigate the prevalence of SARS-CoV-2 infection and clinical characteristics of COVID-19 in children and adolescents with T1D Methods: SARS-CoV-2 infection was defined according to selfreported SARS-CoV-2 nasal swab PCR results (n=210) during the pandemic and seroprevalence of SARS-CoV-2 antibodies (n=85) from Jan to Jun-21. SARS-CoV-2 IgG were assessed using a chemiluminescent immunoassay (CLIA). Clinical characteristics and glycemic control data were collected before (T0) and 3-months after (T1) infection Results: SARS-CoV-2 infection was detected in 39 patients [24 males; median age 13.5 yrs (4.74-19.8); T1D duration 5.49 yrs (0.27-12.6)]: 26 (66.6%) based on positive nasal swab PCR and 13 (33.4%) on positive SARS-CoV-2 IgG. Patients detected by CLIA were asymptomatic. Four patients detected by nasal swab PCR were asymptomatic (15.4%), while the others reported ≥1 symptoms lasting a median of 5 days: fever (46.1%), headache (28.2%), anosmia and/or ageusia (25.6%), nasal congestion (15.4%), fatigue/myalgia (10.2%).
