Background: Pharmacological treatment of obesity and glucose-insulin metabolism disorders in children may be more difficult than in adults. Thus, we evaluate the effects of metformin in comparison with metformin plus a polysaccharide complex (Policaptil Gel Retard(®), PGR) on body weight and metabolic parameters in obese children and adolescents with metabolic syndrome (MetS). Patients and methods: We retrospectively collected 129 children and adolescents (67 girls, 62 boys; median age 12.6 years) treated for a minimum of two years with metformin and low glycemic index (LGI) diet...

OBJECTIVES: Results of surgery for focal CHI in 30 children PATIENTS AND METHODS: All showed an ABCC8 or KCNJ11 mutation. After PET/CT in 29 children and PET/MRT in 1 case, frozen-section guided resection was performed, in left-sided cases by laparoscopy. Mean age at surgery was 11.7 months (2-49). RESULTS: In 28/30 children, the PET/CT or MRT correlated with histopathology. In two cases, a focal lesion was undectable; one of these was cured, one not. In total, 24 children showed lesions with sizes of 5-12 mm...

OBJECTIVE: To our knowledge, data on comparison of myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with polycystic ovary syndrome (PCOS) are limited. This study was carried out to compare myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with PCOS. DESIGN, PATIENTS AND MEASUREMENTS: This randomized controlled trial was conducted among 60 subjects with PCOS aged 18-40 years. Subjects were randomly allocated into two groups to receive either myo-inositol (N=30) or metformin (N=30) for 12 weeks...

SUMMARY: Poland syndrome (PS) is a rare congenital condition, affecting 1 in 30 000 live births worldwide, characterised by a unilateral absence of the sternal head of the pectoralis major and ipsilateral symbrachydactyly occasionally associated with abnormalities of musculoskeletal structures. A baby girl, born at 40 weeks' gestation with birth weight of 3.33 kg (-0.55 SDS) had typical phenotypical features of PS. She had recurrent hypoglycaemic episodes early in life requiring high concentration of glucose and glucagon infusion...

SUMMARY: Hypoglycemia during pregnancy can have serious health implications for both mother and fetus. Although not generally recommended in pregnancy, synthetic somatostatin analogues are used for the management of blood glucose levels in expectant hyperinsulinemic mothers. Recent reports suggest that octreotide treatment in pregnancy, as well as hypoglycemia in itself, may pose a risk of fetal growth restriction. During pregnancy, management of blood glucose levels in familial hyperinsulinemic hypoglycemia thus forms a medical dilemma...

Loss-of-function mutations of β-cell KATP channels cause the most severe form of congenital hyperinsulinism (KATPHI). KATPHI is characterized by fasting and protein-induced hypoglycemia that is unresponsive to medical therapy. For a better understanding of the pathophysiology of KATPHI, we examined cytosolic calcium, insulin secretion, oxygen consumption, and [U-(13)C]glucose metabolism in islets isolated from the pancreases of children with KATPHI who required pancreatectomy. Basal cytosolic calcium ([Ca(2+)] i ) and insulin secretion were higher in KATPHI islets compared to controls...

Congenital hyperinsulinism (CHI) is a rare genetic disorder characterized by inappropriate insulin secretion and severe hypoglycaemia. There are two histological subtypes: diffuse and focal form. Diffuse form is most common in autosomal recessive mutations in ABCC8/KCNJ11 gene, while focal CHI is caused a paternally inherited mutation and a somatic maternal allele loss. Here we report a case of a term male infant presented with severe hyperinsulinaemic hypoglycaemia. Gene panel testing was performed to give rapid genetic diagnosis...

BACKGROUND: Insulinoma associated with pregnancy is a very rare condition and can be difficult to diagnose. Here, we present an interesting case of insulinoma occurring during pregnancy with special attention paid to the use of a continuous glucose monitoring system to detect hypoglycemia. CASE PRESENTATION: A 36-year-old white woman in the second trimester of pregnancy presented with recurrent episodes of hypoglycemia associated with neuroglycopenic symptoms. The use of a continuous glucose monitoring system confirmed hypoglycemia...

Inward rectifier potassium (Kir) channels are expressed in almost all mammalian tissues and play critical roles in the control of excitability. Pancreatic ATP-sensitive K (KATP) channels are key regulators of insulin secretion and comprise Kir6.2 subunits coupled to sulfonylurea receptors. Because these channels are reversibly inhibited by cytoplasmic ATP, they link cellular metabolism with membrane excitability. Loss-of-function mutations in the pore-forming Kir6.2 subunit cause congenital hyperinsulinism as a result of diminished channel activity...

The sulfonylurea receptor 1 (SUR1) protein forms the regulatory subunit in ATP sensitive K(+) (KATP) channels in the pancreas. SUR proteins are members of the ATP binding cassette (ABC) superfamily of proteins. Binding and hydrolysis of MgATP at the SUR nucleotide binding domains (NBDs) lead to channel opening. Pancreatic KATP channels play an important role in insulin secretion. SUR1 mutations that result in increased levels of channel opening ultimately inhibit insulin secretion and lead to neonatal diabetes...

BACKGROUND: Congenital hyperinsulinism (CHI) can present with considerable clinical heterogeneity which may be due to differences in the underlying genetic etiology. We present two siblings with hyperinsulinaemic hypoglycaemia (HH) and marked clinical heterogeneity caused by compound heterozygosity for the same two novel ABCC8 mutations. CASE PRESENTATION: The index patient is a 3-year-old boy with hypoglycaemic episodes presenting on the first day of life. HH was diagnosed and treatment with intravenous glucose and diazoxide was initiated...

BACKGROUND: Mutations in the GCK gene lead to different forms of glucokinase (GCK)-disease, activating mutations cause hyperinsulinaemic hypoglycaemia while inactivating mutations cause monogenic diabetes. Hyperinsulinism (HI) is a heterogeneous condition with a significant genetic component. The major causes are channelopathies, the other forms are rare and being caused by mutations in genes such as GCK. OBJECTIVE: To describe the clinical and genetic presentation of four families with activating GCK mutations, and to explore the pathogenicity of the novel mutation identified through functional studies...

AIM: Congenital hyperinsulinism (CHI) and glycogen storage disease (glycogenosis) are both causing hypoglycemia during infancy, but with different additional clinical features and therapeutic approach. We aimed to identify a genetic cause in a child with an ambiguous phenotype. METHODS AND RESULTS: We present a child with hyperinsulinemic hypoglycemia, physiological 3-OH butyrate, increased triglyceride serum levels, increased level of glycogen in erythrocytes, increased liver transaminases, and increased echogenicity on liver ultrasonography...

REVIEW

Insulinoma is the most common neuroendocrine tumor of the pancreas. Surgical management of insulinomas is considered to be the only curative method. However, effective glycemic control preoperatively and in unresectable insulinomas remains a significant issue. Hyperinsulinism, occurring as a result of the hormone-secreting tumor, leads to life-threatening hypoglycemia episodes which require urgent medical treatment. This article discusses current management of hypoglycemia in insulinoma patients, including: education and lifestyle modifications, pharmacotherapy (diazoxide, somatostatin analogs, mTOR inhibitor - everolimus), cytoreductive methods and continuous glucose monitoring systems...

Placental insufficiency and intrauterine growth restriction (IUGR) of the fetus affects approximately 8% of all pregnancies and is associated with short- and long-term disturbances in metabolism. In pregnant sheep, experimental models with a small, defective placenta that restricts delivery of nutrients and oxygen to the fetus result in IUGR. Low blood oxygen concentrations increase fetal plasma catecholamine concentrations, which lower fetal insulin concentrations. All of these observations in sheep models with placental insufficiency are consistent with cases of human IUGR...
