Patient Q&A Section

What causes congenital hyperinsulinism?

"The pathophysiology of congenital hyperinsulinism is not entirely known. In a recent study, findings, the authors describe one case of congenital hyperinsulinism whose cause remained controversial for several decades." - Anonymous Online Contributor

Unverified Answer

How many people get congenital hyperinsulinism a year in the United States?

"The prevalence of CHI is 1 in 1,500 to 3,000 live births in the United States. With the incidence of CHI per year of approximately 2/100,000 live births, the prevalence of CHI per year in the United States should increase the number of cases being treated by pediatric endocrinology, because many cases of HHI will not be detected." - Anonymous Online Contributor

Unverified Answer

What are common treatments for congenital hyperinsulinism?

"Without specific genetic or medical testing or therapy, most children with HHI will be managed medically with frequent glucose checks, insulin injections, monitoring for hypoglycaemia, and/or lifestyle adjustments. Very few children will require surgery." - Anonymous Online Contributor

Unverified Answer

What are the signs of congenital hyperinsulinism?

"Symptoms usually begin in the first 18 months of life, with excessive hunger and hypoglycaemia as the predominant symptoms. They can be treated and managed with dietary adjustments, and injections of insulin." - Anonymous Online Contributor

What is congenital hyperinsulinism?

"The term 'congenital' relates to the early onset of the condition, from birth. The symptoms of this disorder (the triad of hypoglycaemia, polyuria/polydipsia and failure to thrive) are often present from birth and may not be appreciated by the patient or the parents even at a later stage, and it may be misdiagnosed. A history of polyhydramnios or polyhydramnios-like symptoms from the first month of life leads to a diagnosis of congenital hyperinsulinism. Early surgery may prevent irreversible neurological damage, especially cerebral palsy. Genetic counselling is usually part of the pre-natal diagnosis of hyperinsulinism. © 2014 John Wiley & Sons, Ltd." - Anonymous Online Contributor

Unverified Answer

Can congenital hyperinsulinism be cured?

"Since only one-half of children with CDHI were treated, this study demonstrates that even with definitive treatment, a significant number of patients develop glucose intolerance or Type 1 diabetes by the age of 24 years-a finding that should serve as a call to action of this rare but devastating condition. Even with definitive treatment, all CDHI patients must be followed closely for persistent hyperglycemia and development of diabetes. We speculate that even in mild forms of CDHI, glucose levels should be closely monitored." - Anonymous Online Contributor

What is fluorodopa f 18?

"[The (18)F]fluorodopa PET scan was sensitive in detecting congenital hyperinsulinism in the basal ganglia in our population and was less sensitive in detecting adenomas, particularly in patients with concomitant hypogonadism." - Anonymous Online Contributor

Unverified Answer

Is fluorodopa f 18 typically used in combination with any other treatments?

"The FDG PET scan appears to be a valid imaging modality for assessing treatment response. We did not find any evidence for the use of FDG PET in combination with any other treatment." - Anonymous Online Contributor

Unverified Answer

Does congenital hyperinsulinism run in families?

"Although no single phenotype is associated with increased risk for developing CHI, this is most likely the result of a complex inheritance pattern including both gene-environment interactions and modifier variants." - Anonymous Online Contributor

Unverified Answer

What is the primary cause of congenital hyperinsulinism?

"Primary congenital hyperinsulinism is a complex disorder affecting multiple systems, including the central nervous system and the autonomic system, leading to an increased risk for life-threatening consequences. The hyperinsulinism in HH is thought to be the consequence of a dysfunctional pathway of insulin signaling leading to excess glucose production by beta cells. The insulin resistance underlying HH can be caused by genetic considerations or by an undefined insult during childhood. At least in a minority of the cases, hyperinsulinemia cannot justify the symptoms, even though the primary source in these patients is most frequently attributable to a malfunction of the insulin signaling pathway." - Anonymous Online Contributor

What is the latest research for congenital hyperinsulinism?

"[This list is based on data presented in the Congenital Hyperinsulinism Working Group of the Expert Panel of the European Community Reference Group for Hyperinsulinaemia and Insulin Resistance in Childhood of the European Society of Pediatric Endocrinology and Diabetes (ESPEND) and of the European Society of Endocrinology(http://esend.eurohpg.org/en/profiles_of_research.aspx?Id=33)]\n- A novel mutation is identified in the alpha (SUR1A) and beta (INSR and SLC2A11) subunits of the insulin receptor (IR)." - Anonymous Online Contributor

What does fluorodopa f 18 usually treat?

"This is the first study to report the use of FDG PET in the identification and localization of lesions in patients presenting with neonatal and infantile CHHI. With the imaging, we not only provide valuable information for the clinical diagnosis and follow-up of CHHI, but also confirm the clinical diagnosis of pheochromocytoma which would prove to be the most appropriate initial management." - Anonymous Online Contributor
