The Prevalence of Autonomic and Peripheral Neuropathy in Children and Adolescents with Type 1 Diabetic Mellitus (T1D) and Its Association with the Homozygous Status of Z-2/Z-2 Polymorphism of the Aldose Reductase Gene (AKR1B1) in the Polyol Pathway

Introduction: Diabetic neuropathy (DN) significantly reduces patients’ quality of life and increases cardiovascular death risk. However, it is the least recognized complication of diabetes. Z-2/Z-2 polymorphism of the aldose reductase (AKP1B1) gene increases the expression of the relative enzyme and is likely to contribute to DN expression.Purpose: To study the prevalence of DN in T1D children and adolescents and its associations with the h...

Background: Diabetic neuropathy is among the least recognized complications of diabetes, despite its significant negative impact on survival and quality of life. Characteristic neuronal alterations may occur subclinically early in the course of the disease, even in childhood. The prevalence of subclinical neuropathy in paediatric population ranges from 7.9 – 19% in different studies.Objective and hypotheses: Our objective was to study the prevalence...

Correlation of Sclerostin Levels with Bone Metabolism Markers and Bone Mineral Density in Children and Adolescents with Type 1 Diabetes Mellitus (T1DM)

Background: Sclerostin is an inhibitor of the Wnt/b-catenin bone metabolic pathway. Increased sclerostin levels and reduced bone mineral density (BMD) have been documented in adult patients with diabetes mellitus (DM), predominantly in those with T2DM. No relevant data exist on childhood T1DM.Objective and hypotheses: Our aim was to study plasma sclerostin concentration in children and adolescents with T1DM and controls and to correlate sclerostin levels...

Increased Osteoclast Activity in Children and Adolescents with Type 1 Diabetes Mellitus Indicated by Higher Levels of Osteoprotegerin and s-RANKL may Predispose to Lower Bone Mass

Tsentidis Charalampos , Gourgiotis Dimitrios , Kossiva Lydia , Doulgeraki Artemis , Marmarinos Antonios , Sdogou Triantafillia , Karavanaki Kyriaki

Background: Several bone metabolic pathways seem to be disrupted in patients with type 1 diabetes mellitus (T1DM), leading to reduced bone mass.Objective and hypotheses: Our aim was to study bone metabolism markers in children and adolescents with T1DM and their correlation with bone mineral density (BMD).Method: We evaluated 40 patients (mean±S.D. age 13.04±3.53 years, mean±S.D. T1DM du...

Lower Bone Mineral Density in Type 1 Diabetes Mellitus (T1DM) is Probably Associated with Wnt/β-Catenin Pathway Downregulation Through Increased Dickkopf-1 Levels

Karavanaki Kyriaki , Tsentidis Charalampos , Kossiva Lydia , Marmarinos Antonios , Doulgeraki Artemis , Gourgiotis Dimitrios

Background: Disruption of many bone metabolic pathways and reduced bone mass are associated with diabetes mellitus. Increased fracture risk and elevated Dickkopf-1 and sclerostin levels, which are inhibitors of Wnt/β-catenin pathway, have been found in adult T2DM patients, but no relevant data exist on childhood T1DM.Objective and hypotheses: We aimed at studying plasma Dickkopf-1 and sclerostin concentration in children and adolescents with T1DM an...

Introduction: Paragangliomas are rare neuroendocrine neoplasms, that derive from the chromaffin cells of the neural crest. They originate from the extra-adrenal paraganglia and are divided into sympathetic and parasympathetic. They are classified into three different molecular clusters, depending on the underlying gene mutations, in any of at least 20 identified genes: cluster I Pseudo-hypoxia, cluster II Kinase signaling, cluster III Wnt signaling. Half of th...
