Insights
Infantile hyperinsulinism (HHI) is a neonatal emergency where the brain lacks energy. This review covers HHI diagnosis across infancy and adolescence, including molecular basis and mutations.
Area of Science:
- Pediatric Endocrinology
- Neonatology
- Molecular Genetics
Context:
- Infantile hyperinsulinism (HHI) presents as a critical neonatal emergency.
- Profound hypoglycemia occurs due to excessive insulin secretion, depriving the brain of glucose.
- Timely diagnosis and management are crucial to prevent neurological damage.
Purpose:
- To provide a comprehensive overview of hyperinsulinemic hypoglycemia (HH) diagnosis.
- To extend the diagnostic scope beyond the neonatal period into late infancy and adolescence.
- To detail the molecular alterations and genetic mutations underlying HH.
Summary:
- This review examines the diagnosis of hyperinsulinemic hypoglycemia (HH) across different age groups, from neonates to adolescents.
- It explores the molecular mechanisms and specific genetic mutations responsible for HH.
- The importance of early diagnosis and understanding genetic underpinnings is highlighted.
Impact:
- Enhances understanding of HH diagnostic criteria across developmental stages.
- Facilitates earlier and more accurate diagnosis of HH in infants and adolescents.
- Contributes to the knowledge base for genetic counseling and targeted therapies for HH.
Abstract:
The hypoglycemia hyperinsulinemic of the infancy (HHI) is an emergency in the neonatal period. After a short period of fast the avid brain runs out of its main energy substrate. The authors overhaul the diagnosis of HH, not only in the neonatal period, but also in the late infant and in the adolescence. The aspects of the molecular alterations found in these cases, as well like the description of the main mutations are also approached.
