Introduction: Neonatal diabetes mellitus (NDM) is a rare (1:300,000–400,000 newborns) but potentially devastating metabolic disorder characterized by hyperglycemia combined with low levels of insulin. Two main groups have been recognized, transient NDM (TNDM) and permanent NDM (PNDM).Objective: To describle clinical features and laboratory manifestations of patient with NDM and evaluate outcome of management.Subject and method...

Background: Monogenic diabetes represents a group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes according to age of onset, with neonatal DM (<6 months of age) and maturity onset diabetes of young (MODY) (>6 months and <25 years of age); not every case can be classified into those groups.Objective and hypot...

Background: Hyperinsulinemic hypoglycemia (HH) is a consequence of unregulated insulin secretion by pancreatic β-cells. Congenital HH is caused by mutations in genes involved in regulation of insulin secretion (ABCC8, KCNJ11, GLUD1, CGK, HADH, SLC16A1, HNF4A and UCP2). Severe forms of congenital HH are caused by inactivating mutations in ABCC8 and KCNJ11, which encode the two components of th...

Background: Neonatal diabetes mellitus (NDM), either transient (TNDM) or permanent (PNDM), is a rare form of monogenic diabetes, and usually presents in the first 6 months of life.Objective and Hypotheses: To describe the clinical characteristics and molecular genetics of a large Turkish cohort of NDM from a single centre.Method: NDM patients presenting to Diyarbakır Children State Hospital between 2010 and 2013 were prospecti...

Clinical and Histological Heterogeneity of Congenital Hyperinsulinism Due to Paternally Inherited Heterozygous ABCC8/KCNJ11 Mutations

Context: Congenital hyperinsulinism (CHI) has two main histological types – diffuse and focal. Diffuse CHI is due to recessive or dominant mutations in ABCC8/KCNJ11. Focal disease is due to somatic maternal allele loss of 11p15 in pancreatic β-cells along with paternally inherited germline ABCC8/KCNJ11 mutation. Fluorine-18 L-3, 4-dihydroxyphenylalanine positron emission tomography computerized tomography (18F DOPA–PET...

Background: Dominantly acting loss-of-function mutations in the ABCC8 gene, encoding the sulfonylurea receptor 1 (SUR1) subunit of the β-cell potassium channel (KATP), are usually responsible for mild diazoxide-responsive congenital hyperinsulinism (CHI). In rare cases dominant ABCC8 mutations can cause diffuse diazoxide-unresponsive CHI. Recent reports suggest that medically responsive CHI due to a dominant ABCC8 mutation may confer an increase...

Objective: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycaemia in children. Early identification and management is crucial to prevent irreversible brain damage. CHI has a heterogeneous clinical presentation, histology and molecular biology. We aim to discuss the clinical characteristics and genotype–phenotype correlations of Turkish CHI patients from a single centre.Design and methods: A total of 15 patients with CHI were recr...

Long Acting Somatostatin Analogues in the Management of Congenital Hyperinsulinism in Cases with Poor Compliance to Conventional Therapy

Background: Congenital hyperinsulinism (CHI), is the most common cause of severe hypoglycaemia in neonates and infants. The cornerstone of medical therapy is diazoxide. Octreotide, a somatostatin analogue, is the second therapeutic option in diazoxide unresponsive cases. However, due to its short half-life and requirement of multiple daily doses, lack of compliance may cause recurring hypoglycaemia and related neurological deficits, particularly for the family with low socioec...
