Clinical and Biochemical Characteristics and Treatment Outcomes of Ketosis-Prone Diabetes: The Remission Prone Diabetes.

Abstract

BackgroundDiabetic ketoacidosis (DKA) is one of the severe acute complications of diabetes. It has long been considered a key clinical characteristic of type 1 diabetes mellitus (T1DM) with severe and irreversible deficient insulin levels. Ketosis-prone diabetes (KPD) has pathophysiology close to T2DM but shows signs and symptoms associated with T1DM. In general, patients with ketosis-prone diabetes display elevated glucose and ketone levels; also, a higher hemoglobin A1C than conventional T2DM.ObjectivesThe current research aimed to elucidate the clinical presentation and outline a management plan for KPD in the Indian population.MethodsThe present case series is a descriptive, prospective, and observational case series on six unprovoked cases of KPD. They were managed using the standard protocol of DKA management.ResultsThe recruited cases followed a set pattern of very high insulin requirement at diagnosis. On follow-up, the insulin requirement progressively declined, and all of the cases were able to stop insulin therapy after a mean period of four weeks. None of the cases presented any organ damage at diagnosis. There was no recurrence of DKA during the two-year follow-up. All of the cases had normal liver and renal functions. Autoantibodies were negative in all of the cases.ConclusionsKetosis-prone diabetes is the most under-recognized and under-diagnosed among all types of diabetes. Its recognition is of utmost importance as the approach of its treatment varies widely from that of the conventional type of diabetes. Proper follow-up, especially in unprovoked cases of DKA with obese phenotype, could help elucidate this rare entity of KPD where insulin can be stopped and maintain normoglycemia for a substantial period without insulin.
