RESUMO
Diabetic ketoacidosis (DKA) is a life-threatening complication, which is most common in individuals with type 1 diabetes (T1D) and is a significant risk for morbidity and mortality, and it is an economic burden on individuals, health care systems, and payers. Younger children, minority ethnic groups, and those with limited insurance are at the greatest risk for presentation of DKA at T1D diagnosis. Although monitoring ketone levels is an essential part of acute illness management and for both early detection and prevention of a DKA episode, studies have reported poor adherence to ketone monitoring. Ketone monitoring is particularly important for patients treated with sodium glucose cotransporter 2 inhibitor (SGLT2i) medications, in which DKA can present with only moderately elevated glucose levels, referred to as euglycemic DKA (euDKA). A majority of people with T1D and many with type 2 diabetes (T2D), particularly those using insulin therapy, are using continuous glucose monitoring (CGM) as their preferred method for measurement and management of glycemia. These devices provide a continuous stream of glucose data that enables users to take immediate action to mitigate and/or prevent severe hyperglycemic or hypoglycemic events. An international consensus of leading diabetes experts has recommended the development of continuous ketone monitoring systems, ideally a system that combines CGM technology with measurement of 3-ß-OHB into a single sensor. In this narrative review of current literature, we report on the prevalence and burden of DKA, examine challenges to detecting and diagnosing this condition, and discuss a new monitoring option for DKA prevention.
