Summary
Hypoglycemia during hyperosmolar hyperglycemic crises predicts long-term mortality in diabetes patients. This risk is particularly high when low blood sugar occurs during initial intravenous insulin therapy.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Clinical Research
Background:
- Hypoglycemia during hospitalization is linked to poor outcomes in diabetes patients.
- Limited research exists on the long-term effects of hypoglycemia in patients admitted for hyperglycemic crises.
- Hyperosmolar hyperglycemic crises (HHC) pose significant risks, and hypoglycemia may exacerbate them.
Purpose of the Study:
- To investigate the long-term implications of hypoglycemia in adults hospitalized for hyperosmolar hyperglycemic crises.
- To determine if hypoglycemia during HHC is associated with all-cause mortality.
- To differentiate the prognostic significance of hypoglycemia during different phases of insulin therapy.
Main Methods:
- Retrospective cohort study of 170 patients admitted for HHC (including pure HHC and hyperosmolar diabetic ketoacidosis).
- Analysis of hypoglycemia occurrence during initial intravenous insulin therapy and later subcutaneous insulin therapy phases.
- Long-term mortality assessment with a median follow-up of 652 days.
Main Results:
- Hypoglycemia was observed in 26.5% of patients during initial IV insulin therapy and 52.7% during later SC insulin therapy.
- Both hypoglycemia events were associated with increased long-term mortality.
- After adjusting for confounders, hypoglycemia during initial IV insulin therapy remained a significant predictor of mortality (HR 2.10, p=0.004).
Conclusions:
- Hypoglycemia during hyperosmolar hyperglycemic crises serves as a marker for long-term mortality.
- The occurrence of hypoglycemia during the initial intravenous insulin therapy phase is particularly indicative of increased long-term mortality risk.

Hypoglycemia and Glucagon
257
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Diabetes: Symptoms, Diagnosis, and Complications
528
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Overview of Carbohydrate Metabolism
981
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Diabetes Mellitus: Type 2 and Gestational
2.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Pathophysiology of Diabetes
924
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Oral Hypoglycemic Agents: Biguanides and Glitazones
195
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...
