Insights

Congenital hyperinsulinism (CHI) in infants presents with varied symptoms and requires high glucose administration. Surgery for CHI is effective but can lead to exocrine pancreas dysfunction.

Area of Science:

  • Pediatrics
  • Endocrinology
  • Neonatology

Context:

  • Congenital hyperinsulinism (CHI), also known as persistent hyperinsulinemic hypoglycemia, is a rare but serious condition in infants.
  • Early diagnosis and appropriate management are crucial for preventing neurological damage due to hypoglycemia.

Purpose:

  • To retrospectively analyze the diagnostic methods and treatment outcomes for infants with congenital hyperinsulinism (CHI).
  • To evaluate the effectiveness of diazoxide treatment and subtotal pancreatectomy in managing CHI.
  • To identify potential complications associated with CHI treatment, including neurological and pancreatic dysfunction.

Summary:

  • This study reviewed 15 infants diagnosed with CHI between 1981 and 1999, noting diverse presentations including macrosomia and neuroglycopenic symptoms.
  • Infants required significantly elevated glucose levels (16.9 mg/kg/min) to maintain normoglycemia.
  • Five infants responded to diazoxide, while 10 underwent subtotal pancreatectomy, resulting in normoglycemia in 4, but with 3 developing exocrine pancreas dysfunction. Disturbed neuropsychological development was noted in 5 infants.

Impact:

  • The findings highlight the challenges in diagnosing and managing CHI, emphasizing the need for tailored treatment strategies.
  • Subtotal pancreatectomy is a viable option for refractory cases, but potential long-term complications like exocrine dysfunction must be monitored.
  • This study contributes to understanding the long-term outcomes and management of congenital hyperinsulinism in infants.

Diabetes Mellitus: Introduction

Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...

Pathophysiology of Diabetes

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, suggesting a...
Type I Diabetes I: Introduction01:12

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...

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 II: Pathophysiology01:26

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 Manifestations01:19

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...
