SARS-CoV-2 infection in hospitalized children with type 1 and type 2 diabetes

Abstract

Context

While diabetes is a risk factor for severe illness from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in adults, there is conflicting data surrounding the relationship between the virus and diabetic disease process in children.

Objective

This case series aims to illustrate an increase in the incidence of types 1 and 2 diabetes mellitus (T1DM, T2DM) between April – November 2020 at a large tertiary care children’s hospital and examine the characteristics and adverse outcomes in these children. In addition, two children with significant complications from coronavirus disease 2019 (COVID-19) and diabetes are highlighted.

Methods

Hospitalized children with T1DM or T2DM and SARS-CoV-2 infection were identified, and electronic medical records were reviewed.

Results

We observed a 16.3% increased rate of new-onset T1DM and 205.3% increased rate of new-onset insulin-dependent T2DM between April and November 2020 when compared to the same observational time frame in 2019. Among children with new-onset T1DM, 56.9% presented with DKA in 2019 and 47.1% in 2018 compared to 64.3% in 2020, which was higher than the national average. Twenty-eight children were diagnosed with COVID-19 and diabetes during this time. The 2 described cases with significant complications from COVID-19 and DKA required large doses of intravenous insulin over a prolonged duration.

Conclusion

This study highlights that the COVID-19 pandemic might have led to an increased rate of new-onset T1DM, T2DM, and DKA in children and adolescents compared to a similar time frame in the prior 2 years. The clinical phenotypes and outcomes in children with diabetes to COVID-19 infection may be distinct and therefore, future pediatric specific studies are needed to define the role of SARS-CoV-2.
