Congenital hyperinsulinism (CI) causes severe infant hypoglycemia due to excess insulin. Differentiating focal from diffuse CI is crucial for effective treatment, guiding surgical intervention to prevent brain damage.

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Disorders
  • Genetics

Background:

  • Congenital hyperinsulinism (CI) is a leading cause of hypoglycemia in infants.
  • Uncontrolled insulin oversecretion in CI can lead to severe, irreversible brain damage.
  • Early diagnosis and treatment are critical for managing CI and preventing complications.

Purpose of the Study:

  • To highlight the heterogeneity of congenital hyperinsulinism.
  • To emphasize the importance of distinguishing between focal and diffuse CI lesions.
  • To guide treatment strategies based on CI subtype.

Main Methods:

  • Review of clinical presentations and histopathological findings in CI.
  • Analysis of treatment outcomes for diazoxide therapy and pancreatectomy.

  • Correlation of genetic factors with CI subtypes.

    • Main Results:

    • CI presents with two main histopathological lesions: focal and diffuse, which are clinically similar.
    • Focal CI, often sporadic, responds well to limited pancreatic resection.
    • Diffuse CI, involving genetic factors, may require extensive pancreatectomy with risks of diabetes mellitus.

    Conclusions:

    • Accurate differentiation between focal and diffuse CI is essential for optimal patient management.
    • Targeted surgical resection for focal CI offers better outcomes than pancreatectomy.
    • Understanding the genetic basis of diffuse CI is key to developing long-term therapeutic approaches.
