Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...

Our protocol was developed to cleanly and easily deliver islets or cells under the kidney capsule of mice. Cells are concentrated into pellets in the final tubing used for transplanting the cells under the kidney capsule. The ease of this technique reduces stress to the cells and the mouse.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
FAQs
Reduced effective insulin shifts metabolism toward lipolysis, the breakdown of stored fat. The liver then converts released fat-derived substrates into ketones. As ketones accumulate, they contribute to metabolic acidosis, while blood glucose also rises. This linked sequence explains why DKA laboratory assessment must evaluate both glucose control and acid-base disturbance rather than relying on glucose alone.
Blood glucose indicates hyperglycemia but does not show whether substantial ketone production or metabolic acidosis is present. DKA and hyperosmolar hyperglycemic state can therefore require comparison across several measurements, including serum or urine ketones, blood pH, bicarbonate, and osmolality. Using this broader pattern reveals the metabolic process responsible for the patient’s laboratory abnormalities.
Ketone-driven acidosis reflects increased hepatic ketone production after insufficient effective insulin promotes fat breakdown. Hyperosmolarity instead reflects a highly concentrated blood state associated with more severe hyperglycemia and is typically emphasized in hyperosmolar hyperglycemic state, where ketone formation is minimal. These different dominant processes explain why pH, bicarbonate, ketones, and osmolality provide complementary information.
A focused comparison includes blood glucose, serum or urine ketones, blood pH, bicarbonate, and osmolality. Glucose describes the degree of hyperglycemia, ketones indicate whether hepatic ketone production is prominent, and pH and bicarbonate characterize metabolic acidosis. Osmolality adds information about blood concentration, allowing the overall pattern to distinguish related metabolic conditions.
Begin by assembling the same core measurements for both conditions: glucose, ketones, pH, bicarbonate, and osmolality. Then interpret them as a pattern rather than as isolated values. Prominent ketones with metabolic acidosis support a DKA pattern, whereas more severe hyperglycemia and hyperosmolarity with minimal ketones support a hyperosmolar pattern.
This comparison is useful whenever laboratory findings must be connected to underlying metabolic biology and disease severity. It helps distinguish whether insulin deficiency is producing substantial lipolysis and ketone accumulation or whether severe hyperglycemia and hyperosmolarity dominate. The resulting interpretation supports recognition of the condition being evaluated and informs selection of appropriate clinical management strategies.
