The prevalence of ketosis-prone type 2 diabetes is not known, but observational studies suggest that this type of diabetes accounts for a substantial number of patients with diabetic ketoacidosis. In the United States, the prevalence has been estimated to be between 20% and 50% in African-American and Hispanic patients with new diagnoses of diabetic ketoacidosis . In addition to ethnicity, clinical features predictive of future near-normoglycemic remission are obesity and a family history of type 2 diabetes. Among 154 consecutive African-American patients admitted to the hospital with diabetic ketoacidosis, we observed that obesity was present in 29% and that the prevalence of obesity was higher among those with newly diagnosed diabetes (56%). More than 80% of patients have a family history of type 2 diabetes. The mean body mass index at presentation in African-American patients with ketosis-prone type 2 diabetes has ranged between 28 kg/m2 to 37 kg/m2 . A high rate of obesity is also reported in Hispanic and Chinese persons and in sub-Saharan black African immigrants to Europe. Obesity in persons with diabetic ketoacidosis from minority ethnic groups is more common than in white persons, in whom the rate of obesity is less than 20%.


Balasubramanyan and colleagues reviewed the clinical profiles of 141 adults admitted to the hospital with diabetic ketoacidosis. At presentation, 39% of patients were considered to have type 1 diabetes, 53% were considered to have type 2 diabetes, and 8% were not classified.Twenty-eight percent of patients had newly diagnosed diabetes, 93% of whom were reassessed at least 2 years after their initial episode of diabetic ketoacidosis and were considered to have type 2 diabetes. More recently, Pin˜ero-Pilon˜a and Raskin reported that the incidence of this type of diabetes among persons with new-onset diabetes with diabetic ketoacidosis was approximately 60%. In agreement with the U.S. experience, African studies have reported that 42% to 64% of patients with diabetic ketoacidosis initially treated with insulin therapy do not have classic type 1 diabetes and may experience prolonged remission. The prevalence of ketosis-prone type 2 diabetes seems to be lower in Asian and white persons and may represent fewer than 10% of cases of diabetic ketoacidosis.


Narrative Review: Ketosis-Prone Type 2 Diabetes Mellitus

The extent of the prevalence of this syndrome really isn't known. As far as I know, there is no ready test for KPD T2. What we have is hospital admittance records for DKA. The numbers quoted for Mexican and African Americans is about 60% of all the DKA cases. What this means in terms of the general Mexican and African American population is in question but you have to recognize that for every case where it is bad enough to cause hospitalization there has to be many multiples of it in existence.
