Objective: To report a case of a patient diagnosed with latent autoimmune diabetes of adulthood (LADA) based on clinical presentation and positive glutamic acid decarboxylase antibodies (GAD-abs) that converted to antibody negative diabetes after combined treatment with sitagliptin and vitamin D.Methods: A 31-year-old male presented at the emergency room with symptoms of polyuria, polydipsia, and weight loss. Blood glucose was 300 mg/dl with mild ketonur...

Effect of intracerebroventricular infusion of bombesin in glucose dependent insulinotropic peptide on conscious dogs

Yavropoulou Maria , Anastasiou Olympia , Kotsa Kalliopi , Yovos John

Several studies have pointed to a neural regulation of glucose dependent insulinotropic peptide (GIP) secretion. Bombesin is a neuropeptide found in the amphibian brain and gastrointestinal system – homologous to the C terminus of gastrin-releasing protein (GRP) in mammalians, which displays a wide range of metabolic actions.Aim: Aim of this study was to investigate the effect of intracerebroventicular infusion of bombesin in a centrally mediated re...

Management and long term follow up of hyperparathyroidism in multiple endocrine neoplasia type 1: single center experience

Yavropoulou Maria , Vlachou Sofia , Tsoli Marina , Fostira Florentia , Kaltsas Gregory , Kassi Eva

Background and objective: Multiple Endocrine Neoplasia type 1 (MEN 1) is an autosomal dominant disease characterized by a broad clinical spectrum. Previous multi-center studies, that analyzed large groups of patients with MEN 1 have been reported before but long term follow up data of these patients focusing exclusively on primary hyperparathyroidism (PHPT) are scarce.Patients and Methods: In this retrospective cohort study we include all patients with P...

Pheochromocytomas and paragangliomas-real world data in a tertiary Greek center

Thanasoula Foteini , Angelousi Anna , Kyriakopoulos Georgios , Yavropoulou Maria , Kassi Evanthia , Kaltsas Gregory

Purpose: Pheochromocytomas (PCs) and paragangliomas (PGLs) are rare neuroendocrine tumors arising from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. Metastatic PCs/PGLs occur in about 5-26% of cases. Their management and diagnosis still remain a challenge due to their heterogeneity, the absence of guidelines and the few prognostic tools.Aim: The aim of this study was to describe clinical and gen...

Functional gonadotrophin axis evident as spontaneous puberty in a pediatric patient with hypopituitarism after caniopharyngioma resection: a case report

Rapti Eleni , Grammatiki Maria , Mousiolis Athanasios , Tsekmekidou Xanthippi , Resta Maria , Karras Spyridon , Yavropoulou Maria , Kotsa Kaliopi

Objective: To report a case of hypogonadism reversal and spontaneous puberty in a craniopharyngioma patient who suffered from hypopituitarism as a result of complete surgical resection.Methods: A 13-year-old boy with hypopituitarism was evaluated for right testicular sensitivity.At the age of 6 the child presented with growth arrest and a craniopharyngioma causing pituitary insufficiency was diagnosed. Treatment with hydrocortisnon...

Somatostatin analogue treatment of a TSH secreting adenoma presenting with accelerated bone metabolism and a pericardial effusion

Mousiolis Athanasios , Kotsa Kalliopi , Rapti Eleni , Yavropoulou Maria , Efstathiou Maria , Foroglou Nikolaos , Yovos Ioannis

Objective: To report the unusual presentation of a thyrotropinoma in a patient with: i) accelerated bone turnover, evident as osteopenia and increased serum alkaline phosphatase level, and ii) a pericardial effusion, years before diagnosis, that resolved completely following surgery and somatostatin analogue treatment.Case report: A 38-year-old man had been treated for years for presumed hypothyroidism with thyroxine supplementation based on elevated TSH...

Glucose metabolism in primary hyperparathyroidism: The role of parathyroidectomy

Antonopoulou Vasiliki , Grammatiki Maria , Rapti Eleni , Koufakis Theocharis , Karras Spyridon , Yavropoulou Maria , Papavramidis Theodossis , Kotsa Kalliopi

Background: Although primary hyperparathyroidism (PHPT) has been associated with diabetes mellitus (DM), the etiological link is not clear and the effect of parathyroidectomy is controversial.The aim of this observational study was to investigate the metabolic link between calciotropic hormones and glucose metabolism in PHPT patients before and after parathyroidectomy.Methods: Twenty-four consecutive patients with PHPT (Group-A) without DM were included ...

Anti-diabetic treatment as an additional factor in a FRAX based evaluation of osteoporotic fracture risk

Yavropoulou Maria P , Mousiolis Athanasios , Kolokouri Vasiliki , Kolimpianaki Pelagia , Dimitriou Athina , Papalexis Petros , Daniilidis Michael , Kotsa Kalliopi

Background: The present study is designed to assess the incidence of osteoporotic fractures and the associated risk factors and particularly those used to predict the 10-year fracture risk in FRAX score based on data gathered in general practitioner’s records of rural Greece.Patients and methods: We conducted a retrospective analysis of all patients with osteoporosis presented between October 2013 and December 2014. Data from medical records includi...

Yavropoulou Maria , Panayotou Gregory , Topouridou Konstantina , Panteliadou Anastasia , Karayannopoulou Georgia , Zaraboukas Thomas , Goropoulos Apostolos , Yovos John , Pazaitou Kaliopi

Background: Vitamin D receptor (VDR) and progesterone receptor (PR) expression have been described before in papillary thyroid carcinoma but data regarding association of this expression with tumour histological characteristics are scarce.Materials and methods: Formalin-fixed, paraffin-embedded specimens from adult patients with papillary thyroid carcinoma (PTC), who underwent total thyroidectomy from 2009 to September 2012 were retrieved. Data regarding...

Changes in the relative expression of circulating microRNAs linked to bone metabolism in HIV-infected Individuals with low bone mass

Yavropoulou Maria , Kolynou Artemis , Makras Polyzois , Skoura Lemonia , Nanoudis Sideris , Pikilidou Maria , Tsave Olga , Metallidis Simeon , Chatzidimitriou Dimitris

Objective: Human immunodeficiency virus (HIV)-infected patients demonstrate an increased risk of osteoporosis and fractures. The pathophysiology of HIV-induced bone loss is complex and remains largely unknown. Recent studies have identified a molecular signature of small non-coding RNAs (microRNAS) in patients with osteoporosis, but data are lacking in HIV-infected patients. The aim of the present study was to investigate the expression profile of microRNAs related to bone met...
