To evaluate whether the diagnosis of pediatric type 1 diabetes or its acute complications changed during the early phase of the coronavirus disease 2019 (COVID-19) pandemic in Italy. RESEARCH DESIGN AND METHODS This was a cross-sectional, Web-based survey of all Italian pediatric diabetes centers to collect diabetes, diabetic ketoacidosis (DKA), and COVID-19 data in patients presenting with new-onset or established type 1 diabetes between 20 February and 14 April in 2019 and 2020. RESULTS Fifty-three of 68 centers (77.9%) responded. There was a 23% reduction in new diabetes cases in 2020 compared with 2019. Among those newly diagnosed patient who presented in a state of DKA, the proportion with severe DKA was 44.3% in 2020 vs. 36.1% in 2019 (P 5 0.03). There were no differences in acute complications. Eight patients with asymptomatic or mild COVID-19 had laboratory-confirmed severe acute respiratory syndrome coronavirus 2. CONCLUSIONS The COVID-19 pandemic might have altered diabetes presentation and DKA severity. Preparing for any "second wave" requires strategies to educate and reassure parents about timely emergency department attendance for non-COVID-19 symptoms. At its peak, coronavirus disease 2019 (COVID-19) significantly reduced pediatric emergency department (ED) access, most likely due to the fear of infection (1). During the pandemic, the International Society for Pediatric and Adolescent Diabetes received information from its members about several new type 1 diabetes cases or diabetic ketoacidosis (DKA) episodes where hospitalization was delayed due to the closure of non-COVID-19 services (2). There were also concerns that parents had delayed seeking timely medical advice for children with symptoms of diabetes or DKA, resulting in increased numbers of presentations of severe DKA. Based on these anecdotal cases in Italy and other countries (2), we hypothesized that the COVID-19 pandemic might have affected the number of new diabetes diagnoses and the severity of DKA. We therefore conducted a survey to evaluate whether the diagnosis of pediatric type 1 diabetes or its acute complications changed during the early phase of the COVID-19 pandemic in Italy compared with the same period in 2019.
