Insights

DiaPep277 treatment is safe for children with recent-onset type 1 diabetes mellitus (T1DM). However, this peptide therapy did not preserve beta-cell function or improve metabolic control in the study.

Area of Science:

  • Immunology
  • Endocrinology
  • Pediatrics

Background:

  • Type 1 diabetes mellitus (T1DM) is an autoimmune disease targeting insulin-producing beta cells.
  • DiaPep277, a heat-shock protein 60 (hsp60) derived peptide, showed promise in slowing beta-cell function decline in prior studies.
  • Evaluating DiaPep277's efficacy in preserving beta-cell function in children with recent-onset T1DM is crucial.

Purpose of the Study:

  • To assess the efficacy and safety of DiaPep277 in children with recent-onset T1DM.
  • To determine if DiaPep277 can attenuate beta-cell destruction and improve metabolic control.
  • To evaluate long-term outcomes of DiaPep277 treatment in pediatric T1DM.

Main Methods:

  • Prospective, randomized, double-blind, phase II clinical trial.
  • 30 children (7-14 years) with recent-onset T1DM received 1 mg DiaPep277 or placebo (mannitol) via subcutaneous injection.
  • Follow-up was 18 months, comparing stimulated C-peptide, insulin dose, and HbA1c.

Main Results:

  • C-peptide levels decreased similarly in both DiaPep277 and placebo groups.
  • No significant differences were observed in insulin dose or HbA1c between treatment groups.
  • No serious drug-related adverse effects were reported during the study.

Conclusions:

  • One-year treatment with 1 mg DiaPep277 is safe and well-tolerated in children with recent-onset T1DM.
  • DiaPep277 did not demonstrate a beneficial effect on preserving beta-cell function.
  • The study found no improvement in metabolic control with DiaPep277 treatment in this pediatric population.

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 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 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...

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 I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Type I Diabetes III: Clinical Manifestations

Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
