Abstract

CONTEXT: Congenital hyperinsulinism (HI) is the most common cause of hypoglycemia in children. The risk of permanent brain injury in infants with HI continues to be as high as 25-50% due to delays in diagnosis and inadequate treatment. Congenital HI has been described since the birth of the JCEM under various terms, including "idiopathic hypoglycemia of infancy," "leucine-sensitive hypoglycemia," or "nesidioblastosis." EVIDENCE ACQUISITION: In the past 20 years, it has become apparent that HI is caused by genetic defects in the pathways that regulate pancreatic β-cell insulin secretion. EVIDENCE SYNTHESIS: There are now 11 genes associated with monogenic forms of HI (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1), as well as several syndromic genetic forms of HI (eg, Beckwith-Wiedemann, Kabuki, and Turner syndromes). HI is also the cause of hypoglycemia in transitional neonatal hypoglycemia and in persistent hypoglycemia in various groups of high-risk neonates (such as birth asphyxia, small for gestational age birthweight, infant of diabetic mother). Management of HI is one of the most difficult problems faced by pediatric endocrinologists and frequently requires difficult choices, such as near-total pancreatectomy and/or highly intensive care with continuous tube feedings. For 50 years, diazoxide, a KATP channel agonist, has been the primary drug for infants with HI; however, it is ineffective in most cases with mutations of ABCC8 or KCNJ11, which constitute the majority of infants with monogenic HI. CONCLUSIONS: Genetic mutation testing has become standard of care for infants with HI and has proven to be useful not only in projecting prognosis and family counseling, but also in diagnosing infants with surgically curable focal HI lesions. (18)F-fluoro-L-dihydroxyphenylalanine ((18)F-DOPA) PET scans have been found to be highly accurate for localizing such focal lesions preoperatively. New drugs under investigation provide hope for improving the outcomes of children with HI.

  • Mechanistic data on adult-onset NIPHS is scarce, whereas the pathophysiology of persistent hyperinsulinemic hypoglycemia in childhood and infancy is well understood genetically and functionally.

    “While the pathophysiology of persistent hyperinsulinemic hypoglycemia in childhood and infancy, which is morphologically similar to NIPHS, is well understood from a genetic and functional point of view, mechanistic data on adult-onset NIPHS is scarce [49].”

    From An Uncommon Cause of Recurrent Presyncope, Dizziness, and Tachycardia: A Case Report of Diffuse, Adult-Onset Nesidioblastosis/Non-Insulinoma Pancreatogenous Hypoglycemia Syndrome (NIPHS) (2023) · cites this paper as [49]

    The Abstract (page unavailable) describes genetic causes of congenital hyperinsulinism and advances in understanding pancreatic β-cell insulin secretion, supporting the childhood and infancy portion of the claim. The copy does not address whether mechanistic data on adult-onset NIPHS are scarce or establish the asserted morphological similarity; searches for NIPHS and adult nesidioblastosis found no such discussion.

  • Loss-of-function mutations in KATP channel genes cause congenital hyperinsulinism because they result in permanent membrane depolarization and persistent insulin release.

    “Loss-of-function mutations cause congenital hyperinsulinism because they result in permanent membrane depolarization and persistent insulin release (479, 644, 681).”

    From Pancreatic β-Cell Electrical Activity and Insulin Secretion: Of Mice and Men (2018) · cites this paper as [644]

    The KATP-HI form section says inactivating KATP-channel mutations cause congenital hyperinsulinism. The Pathways of β-Cell Insulin Secretion section explains that KATP-channel closure depolarizes the membrane and triggers insulin release. The paper does not establish permanent depolarization for all such mutations; it describes some dominant mutations with residual channel activity. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
