Diabetes Presentation in Infancy: High Risk of Diabetic Ketoacidosis

Diabetes in childhood has been associated with increased morbidity and mortality, but the risks for diabetes in infancy remain unclear. Cases with onset of hyperglycemia in the first 6 months of life consist predominantly of monogenic diabetes, whereas type 1 autoimmune diabetes accounts for the majority of cases beyond this threshold. Regardless of etiology, diabetes symptoms tend to be difficult to recognize in an infant, putting patients at increased risk for delays in diagnosis, which may lead to higher blood glucose levels and diabetic ketoacidosis (DKA) at presentation. Here, we report a high degree of morbidity among a cohort of subjects with infancy-onset diabetes.We examined diagnosis records from 88 cases with diabetes onset ≤13 months of age collected through the University of Chicago Monogenic Diabetes Registry (1). We assessed laboratory values and sign/symptoms, and if a causal mutation for diabetes was detected, participants were subdivided by similar mutation subtypes. Data were managed using REDCap electronic data capture tools and analyzed using Stata version 14 (StataCorp, 2015).The majority of participants were male ( n = 46, …
