With reference to non-ketotic, hyperglycemia, hyperosmolar state (HHS) consider the following statements -

Hyperosmolar hyperglycemic syndrome (HHS) is a clinical condition that arises from a complication of diabetes mellitus. This problem is most commonly seen in type 2 diabetes. Won Frerichs and Dreschfeld first described the disorder around 1880. They described diabetic patients with profound hyperglycemia and glycosuria without the classic Kussmaul breathing or acetone in the urine seen in diabetic ketoacidosis. This clinical condition was formerly called non-ketotic hyperglycemic coma; hyperosmolar hyperglycemic non-ketotic syndrome, and hyperosmolar non-ketotic coma (HONK). Ref - pubmed.com
