Insulin treatment in type 1 diabetes
1Department of Medicine, University of Perugia, Italy.
Summary
Insulin analogues offer improved glycemic control for type 1 diabetes, enhancing hemoglobin A1c and reducing glucose fluctuations. These advanced insulin therapies provide safer and more effective management strategies for patients.
Area of Science:
- Endocrinology
- Metabolic Diseases
Background:
- Type 1 diabetes mellitus requires lifelong insulin therapy for glycemic control.
- Optimizing insulin regimens is crucial for preventing long-term complications.
Purpose of the Study:
- To outline key strategies for insulin therapy in type 1 diabetes.
- To review the advantages and limitations of various insulin regimens and analogues.
Main Methods:
- Discussion of limitations and advantages of different insulin regimens.
- Review of insulin analogue properties and clinical use.
Main Results:
- Rapid-acting insulin analogues offer superior postprandial glucose control compared to regular human insulin.
- Insulin pumps provide the most physiologic insulin replacement; analogues like glargine/detemir with mealtime rapid-acting analogues are effective alternatives.
- NPH insulin is not suitable for continuous basal coverage due to its pharmacokinetic profile.
Conclusions:
- Insulin analogues (rapid- and long-acting) improve glycemic control, lowering hemoglobin A1c and reducing glucose variability.
- These analogues decrease hypoglycemia, especially nocturnal episodes.
- Physiologic insulin regimens are recommended for optimal type 1 diabetes management.

01:16Insulin: 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...

01:15Diabetes: 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.

01:22Diabetes 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...

01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
01:27Insulin 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.

01:26Type 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...
