Ketosis-prone diabetes

Ketosis-prone diabetes or KPD is an intermediate form of diabetes that has some characteristics of type 1 and some of type 2 diabetes. However, it is distinct from latent autoimmune diabetes, an intermediate diabetes which is known as type 1.5.

KPD is readily diagnosible because it presents a single characteristic, ketoacidosis, which if present, confirms it as ketosis-prone diabetes. KPD comes in four forms depending upon the presence or absence of β-cell autoantibodies (A+ or A−) and β-cell functional reserve (β+ or β−).
