Congenital hyperinsulinism (CHI) is a complex heterogeneous disease affecting 1 in 40.000 newborns. Recurrent hypoketotic hypoglycaemia led to permanent mental and motor disabilities in 30-40% of children. Histologically three types had been differentiated: focal, diffuse and atypical. Up to now, only focal-type CHI can be permanently cured by focus removal. Focal-type CHI is characterized by paternal inherited mutation of ABCC8 or KCNJ11 mutations. Therefore mutation anal...

Experience Based on 193 18F-DOPA PET CTs in Patients with Congenital Hyperinsulinism: Pearls and Pitfalls in Imaging Diagnostics in Patients with CHI

Kuhnen Peter , Prasad Vikas , Brenner Winfried , Mohnike Wolfgang , Blankenstein Oliver

Background: In congenital hyperinsulinism (CHI) 18F-DOPA PET CT plays an essential role in differentiating between focal and diffuse CHI forms and in the analysis of the localization of a potential focus before surgery.Objective and hypotheses: The aim of this retrospective analysis was the evaluation of the 18F-DOPA PET CT efficacy in a large cohort of CHI patients.Method: In the last few years 193 18</s...

Somatic Paternal UPD on Chromosome 11p15 in Focal Form of Congenital Hyperinsulinism (CHI) Causes Monoallelic Expression of Mutant ABCC8 and KCNJ11

Background: Congenital hyperinsulinism (CHI) is a disorder characterised by dysregulation of insulin secretion that leads to severe hypoglycaemia in neonates and infants. The focal form of CHI is caused by an autosomal recessive mutation in the genes ABCC8 or KCNJ11 inherited from the father and a second somatic event in the affected islet of Langerhans.Objective: We report molecular genetic examination of focal pancreatic lesions of patients receiving t...
