[Ketosis prone type 2 diabetes (KPD)].

Ketosis prone type 2 diabetes (KPD) is presently a well-defined clinical entity, characterized by a debut with severe hyperglycemia and ketoacidosis similar to the presenting form of Type 1 diabetes mellitus (DM1). However, it appears in subjects with Type 2 diabetes mellitus (DM2) phenotype. This situation is caused by an acute, reversible dysfunction of the beta cell in individuals with insulin resistance. Once the acute stage subsides, patients behave as having a DM2 and do not require insulin treatment. They should be kept on a diet and oral hypoglycemic drugs due to their susceptibility to have recurrent acute ketotic decompensations.
