The surgical treatment of hyperinsulinism in infancy and childhood

Insights

Infantile hyperinsulinaemic hypoglycaemia can be transient or persistent. For persistent cases, particularly nesidioblastosis or insulinoma, increased pancreatic resection (up to 90%) is suggested for infants.

Area of Science:

  • Pediatric Endocrinology
  • Surgical Gastroenterology
  • Neonatal Medicine

Background:

  • Hyperinsulinaemic hypoglycaemia in infancy presents as transient or persistent forms.
  • Persistent cases stem from nesidioblastosis (diffuse pancreatic endocrine abnormality) or islet cell adenoma.
  • Untreated persistent hypoglycaemia can lead to severe neurological damage or death.

Observation:

  • Medical therapy is effective for transient hypoglycaemia and some persistent cases.
  • Islet cell adenomas and many nesidioblastosis cases necessitate surgical intervention (partial or total pancreatectomy).
  • This study reviews the surgical management of seven patients (six infants, one child).

Findings:

  • Five infants were diagnosed with nesidioblastosis.
  • One infant and one nine-year-old girl had an islet cell adenoma.
  • Surgical outcomes for these conditions were evaluated.

Implications:

  • For infants with suspected hyperinsulinaemic hypoglycaemia and no evidence of insulinoma, a more extensive initial pancreatectomy (up to 90%) is proposed.
  • This contrasts with the previously recommended 75% resection.
  • Optimizing surgical strategy may improve outcomes for persistent infantile hypoglycaemia.

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...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Insulin: Biosynthesis, Chemistry, and Preparation

The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.
Damage or functional impairment of β-cells inhibits insulin production, leading to diabetes. Diabetes treatment primarily uses...

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...
Hypoglycemia and Glucagon01:15

Hypoglycemia 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...
