What are the best treatments for Congenital Hyperinsulinism?

TL;DR: The primary goal in treating Congenital Hyperinsulinism is to maintain safe blood glucose levels to prevent neurological damage, typically achieved through a combination of pharmacological therapy and, when necessary, surgical intervention. Treatment is highly personalized based on the genetic subtype and the patient's specific response to medication.

What are the first-line medical treatments for Congenital Hyperinsulinism?

The management of Congenital Hyperinsulinism begins with stabilizing blood glucose. First-line pharmacological therapy usually involves diazoxide (Proglycem), which acts as a potassium channel opener to inhibit insulin secretion. For patients who are unresponsive to diazoxide, other medications may be utilized, including octreotide (Sandostatin) or lanreotide (Somatuline), which are somatostatin analogs that help suppress insulin release.

When is surgery required for Congenital Hyperinsulinism?

If medical management fails to stabilize blood glucose levels, surgical intervention becomes necessary, particularly in patients with focal lesions. A specialized surgeon may perform a partial pancreatectomy to remove the affected area of the pancreas. In cases of diffuse Congenital Hyperinsulinism where surgery is not curative, a near-total pancreatectomy may be considered, though this carries a high risk of developing diabetes later in life.

Which specialists should be on the care team?

Managing Congenital Hyperinsulinism requires a multidisciplinary approach to address the complex metabolic and developmental needs of the patient. An ideal care team includes:

• Pediatric Endocrinologist: To lead metabolic management and glucose monitoring.


• Pediatric Surgeon: Experienced specifically in pancreatic surgery for hyperinsulinism.


• Geneticist: To identify the specific mutation, which dictates the clinical path.


• Dietitian: To manage frequent feedings and specialized nutritional needs.


• Neurologist: To monitor for potential complications related to recurrent hypoglycemia.

How does treatment effectiveness vary?

Treatment success in Congenital Hyperinsulinism is highly variable and depends largely on the underlying genetic cause. Patients with focal disease often achieve a cure through surgery, whereas those with diffuse disease may require long-term medication or complex management strategies. At DiseaseMaps.org, 5 community members have shared that personalized, subtype-specific care is essential for managing the long-term impact of Congenital Hyperinsulinism.
