Insulin: Dosing Regimen and Adverse Effects01:16

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Insulin Formulations: Types and Delivery

Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into rapid-acting...
Diabetes Mellitus: Overview and Type I Subtype01:22

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
Type II Diabetes II: Pathophysiology01:24

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.

Area of Science:

  • Critical care medicine
  • Biomedical engineering
  • Clinical informatics

Background:

  • Critically ill patients often experience hyperglycemia, necessitating precise glucose management.
  • Traditional insulin infusion protocols can lead to glucose variability and suboptimal control.
  • Advanced control algorithms offer potential for improved glycemic management in intensive care units.

Purpose of the Study:

  • To evaluate the effectiveness of an enhanced Model Predictive Control (eMPC) algorithm for intravenous insulin infusion.
  • To assess the eMPC algorithm's ability to achieve tight glucose control in critically ill patients over 72 hours.
  • To compare the eMPC algorithm's performance against standard care in two distinct intensive care unit (ICU) settings.

Main Methods:

  • A two-center, open-label, randomized clinical trial comparing eMPC-guided insulin infusion with standard care.
  • Thirty-four critically ill patients with hyperglycemia were enrolled in two university hospital ICUs.
  • Patients were randomized to receive insulin infusion guided by the eMPC algorithm or the ICU's standard protocol.

Main Results:

  • The eMPC algorithm achieved similar time-weighted average glucose concentrations (104 mg/dL) in both ICUs.
  • Standard care resulted in significantly different glucose concentrations between ICUs (128 vs. 99 mg/dL).
  • The glucose measurement interval advised by eMPC differed significantly between ICUs (1.1 vs. 1.8 hours).

Conclusions:

  • The eMPC algorithm demonstrated feasibility for effective and safe tight glucose control in critically ill patients.
  • The eMPC algorithm provided consistent glycemic control across different ICU management protocols.
  • Further research is needed to optimize the glucose sampling interval for the eMPC algorithm while minimizing hypoglycemia risk.
