Summary
Sepsis causes hyperglycemia by inducing hepatic insulin resistance, impacting immune responses. Controlling blood glucose in critically ill patients may reduce mortality and morbidity through anti-inflammatory and antioxidant effects.
Area of Science:
- Endocrinology and Metabolism
- Immunology
- Critical Care Medicine
Context:
- Sepsis triggers hyperglycemia due to hepatic insulin resistance and increased glucose uptake by non-insulin-dependent tissues.
- Hyperglycemia exacerbates inflammatory and immune responses, increasing reactive oxygen species production.
- Blood glucose regulation involves hormones, neurological mechanisms, and hepatic autoregulation, utilizing glucose transporters (GLUT).
Purpose:
- To explore the intricate relationship between sepsis, hyperglycemia, and glucose metabolism.
- To investigate the mechanisms by which blood glucose control impacts outcomes in critically ill patients.
- To highlight the potential of blood glucose level as a therapeutic target in sepsis management.
Summary:
- Sepsis-induced hyperglycemia results from hepatic insulin resistance, leading to increased glucose load and uptake by non-insulin-dependent tissues.
- Hyperglycemia adversely affects inflammatory and immune reactions, potentially worsening sepsis outcomes.
- Maintaining blood glucose control below or equal to 1.4 g/l in critically ill patients may decrease mortality and morbidity, likely via multifactorial mechanisms.
Impact:
- Blood glucose control emerges as a critical factor in managing sepsis and improving outcomes in critically ill patients.
- Understanding the interplay between sepsis and glucose metabolism can lead to more targeted therapeutic strategies.
- Further research is needed to elucidate the optimal blood glucose levels and confirm the benefits of tight glycemic control in sepsis.

01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

01:02Glucose Homeostasis: Regulation of Blood Glucose
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.

01:15Hypoglycemia and Glucagon
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...
01:26Hypoglycemia
Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
01:25Diabetic Ketoacidosis l: Introduction
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...
01:22Diabetic Ketoacidosis ll: Pathophysiology
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...
