Cathepsin K is a cysteine protease known for its importance in bone remodelling. Inhibitors of cathepsin K are in clinical trials for osteoporosis treatment, but side effects included altered levels of related cathepsins in peripheral organs and in the central nervous system (CNS). Importantly, cathepsin K has been identified not only in osteoclasts but also in most epithelia and, recently, in brain parenchyma. Lately, we have also shown that cathepsin K deficiency in mice ind...

Introduction: Pasireotide is a multi-receptor targeted somatostatin analogue with high affinity for sst5, which is commonly expressed in corticotroph adenomas, thus having potential as therapy for Cushing’s disease.Methods: One hundred and sixty-two patients with persistent/recurrent or de novo (if not surgical candidates) Cushing’s disease were randomized (double-blind) to pasireotide 600 μg (n=82) or 900 μg ...

Introduction: Clinical symptoms in craniopharyngioma have been repeatedly described in the literature, but few studies have addressed the issue of acute-onset symptoms in children or adults. Refinements of diagnostic procedures and altered scanning routines over the last two decades may in theory have affected patterns of clinical presentation.Objective: To study the clinical phenotype of patients with newly diagnosed craniopharyngioma, with focus on var...

Introduction: The multi-receptor targeted somatostatin analogue pasireotide has demonstrated efficacy in reducing cortisol in patients with Cushing’s disease in a large, randomized, double-blind, Phase III study. The effects of pasireotide on the signs and symptoms of Cushing’s disease were also investigated as secondary objectives in this trial.Methods: Adult patients with persistent/recurrent or de novo Cushing’s disease were rand...

Studies have demonstrated that ATP-sensitive potassium channel (KATP) subunits SUR2A (sulfonylurea receptor) and KIR6.2 are involved in glucose uptake into skeletal muscle. It is known that the glucose transporter 4 (GLUT4) expression is highest in oxidative type I fibers, pointing out the important role of oxidative muscles as glucose uptakes. Considering these aspects the aim of this study was to investigate whether KATP channel can influence glucose uptake in oxidative musc...

Introduction: Considering the high capacity of water transport of Na+/glucose cotransporter SGLT1, the aim of this study was to investigate the potential role the SGLT1 in luminal membrane of ductal cells of salivary glands upon the non-stimulated salivary secretion of diabetic rats. The present study also investigates the presence of glucose transporter GLUT1 in salivary glands of rats.Methods: Non-stimulated salivary secretion and SGLT1/GLUT1 protein (...

Objective: Congenital adrenal hyperplasia results from 21-hydroxylase deficiency in more than ninety percent of cases. The classical form of 21-hydroxylase deficiency presents in the neonatal period with virilization or adrenal insufficiency, with or without concurrent salt wasting. We report on a rare case of classic 21-hydroxylase deficiency diagnosed in late adulthood.Case report: A 39-year-old male patient presented for workup of infertility. Urologi...

Graves’ Disease (GD) affects about 2% of the population in the UK, with female predominance. A proportion of GD patients (5–50%) develop orbitopathy (GO), which is characterized by tissue remodeling in the orbit leading to protrusion of the eye (proptosis). Blood biomarkers associated with GD or GO could be useful diagnostic or prognostic tools for researchers and clinicians. Within the framework of INDIGO IAPP-612116 (Investigation of Novel biomarkers and Definition...

BackgroundHormone replacement therapy is often used for hypopituitarism, which leads to dysglycemia. This study is conducted to assess the glucose metabolism conditions using the flash glucose monitoring system (FGMS) in patients with hormone replacement therapy.MethodSeven patients who were diagnosed as hypopituitarism and treated with glucocorticoids and L-Thyroxine were qualified to participate in this stu...

Introduction: Refractory hypothyroidism is associated with significantly increased morbidity and healthcare costs. During the evaluation of refractory disease, a thyroxine absorption test is frequently performed using different protocols. We assessed the usefulness of the supervised rapid thyroxine absorption test in a low-resource setting and formulated a useful model to determine the expected FT4 rise in hypothyroid patients without known malabsorption.<p class="abstext"...
