Early Glargine (Lantus) in DKA Management in Children With Type 1 Diabetes

April 14, 2022 updated by: University of Colorado, Denver

Management of Diabetic Ketoacidosis in Children: Does Early Glargine Prevent Rebound Hyperglycemia?

A frequent complication in the management of diabetic ketoacidosis (DKA) in children with type 1 diabetes is rebound hyperglycemia (blood glucose over 180 mg/dL) which increases the risk of re-developing DKA and can lengthen the hospital stay. The investigators want to study whether giving the long-acting insulin glargine (Lantus®) early in DKA management (versus after complete resolution of the DKA) helps prevent rebound hyperglycemia and makes the transition to insulin injections easier. Participants will also have the option to wear a continuous glucose monitor (CGM) during the study to help us understand blood glucose control during and after DKA.

Detailed Description

Diabetic ketoacidosis (DKA) remains the leading cause of morbidity and mortality in children with type 1 diabetes (T1D) and the incidence of T1D is increasing. A frequent complication in DKA management that is associated with in-hospital mortality and longer hospital stay is hyperglycemia; specifically rebound hyperglycemia (defined as a serum glucose greater than 180 mg/dL) within 12-24 hours after correction of the DKA. Rebound hyperglycemia increases the patient's risk of re-developing DKA. Few adult studies suggest that giving the long-acting insulin analog (glargine or Lantus®) early in the management of DKA (i.e. while still receiving intravenous insulin) can reduce rebound hyperglycemia without an increased risk of hypoglycemia and result in a smoother transition from intravenous insulin to subcutaneous insulin. This has not been well-studied in children to date. In this study the investigators want to determine whether giving glargine early in DKA management in children results in reduced rebound hyperglycemia without an increased risk in hypoglycemia. The investigators will do this by randomizing participants in DKA to either receive glargine early in the management of DKA (study group) or after resolution of DKA (control group); the latter is currently standard-of-care. Additionally, continuous glucose monitoring (CGM) systems have not been studied in a pediatric population with DKA. These devices measure blood sugar levels every 5 minutes and provide a great deal of information about blood sugar control patterns over many days. Not only will the use of CGM in this study provide meaningful information regarding blood sugar patterns during DKA treatment, it will also broaden the investigators knowledge of whether CGM is a feasible and accurate tool to use in this setting.
