Diabetic nephropathy: is it always there? Assumptions, weaknesses and pitfalls in the diagnosis
Kyriakos Ioannou
Diabetic nephropathy is defined as a microvascular complication of the kidneys induced by diabetes mellitus and is characterized by albuminuria and progressive loss of kidney function. However, neither albuminuria nor glomerular filtration rate decline are diabetic nephropathy-specific markers, thus the diagnosis of diabetic nephropathy greatly …

Androgen receptors in early and castration resistant prostate cancer: friend or foe?
Vassiliki Pelekanou, George Notas, Efstathios N. Stathopoulos, Elias Castanas, Marilena Kampa
Prostate cancer is one of the most common malignancies and causes of death among men in western societies. It has thus attracted the interest of the scientific community, which has resulted in great improvements in survival rates in recent years. As early as the 1940s, Huggins and Hodges first demonstrated that prostate cancer is androgen dependent …
A Paradox: The Roles of Inositolphosphoglycans in mediating insulin sensitivity and Hyperandrogenism in the Polycystic Ovary Syndrome
Kai I. Cheang, Paulina Essah, John E. Nestler
Current evidence suggests that insulin resistance contributes to the pathophysiologic features of the polycystic ovary syndrome (PCOS). The observation that insulin resistance is a central feature of PCOS leads to studies of the insulin signaling system in this disorder. This article reviews the possible role of putative insulin mediators, inositolphosphoglycans (IPG) mediators, in PCOS. We will focus on how IPGs mediate (a) hyperandrogenism and (b) insulin sensitivity in this disorder…

DESIGN: Eighty-three PCOS women and 64 healthy women were studied. Patients and controls were subdivided into two groups …

OBJECTIVE: This study aimed at exploring to what extent psychosocial factors, such as religiosity/spirituality and sense of coherence, mediate the negative effects of stress on a variety of cardiometabolic indicators, i.e., hypertension, diabetes, cardiovascular and cerebrovascular disease, and atherosclerotic bio-clinical markers …
The-2548G/A polymorphism in the human leptin gene promoter region is associated with plasma free leptin levels; interaction with adiposity and gender in healthy subjects
Nikos Yiannakouris, Labros Melistas, Mary Yannakoulia, Keisha Mungal, Christos S. Mantzoros
A common -2548G/A promoter variant of the human leptin gene has recently been shown to be associated with variations in circulating leptin levels but available data are still conflicting. The aim of this study was to explore potential associations between the -2548G/A polymorphism and adiposity-related variables, plasma total leptin levels …
Antithyroid drugs used in the treatment of hyperthyroidism during breast feeding. An update and new perspectives
Spyros Karras, Themistoklis Tzotzas, Gerasimos E. Krassas
Antithyroid drugs (ATD) are widely used by endocrinologists all over the world for the treatment of Graves’ disease (GD) in the general population and in lactating thyrotoxic mothers.1,2 Traditionally, these agents produce minor side effects (rash, fever, urticaria) in 5-10% of the treated patients …

Grigorios Rombopoulos, Magdalini Hatzikou, Dimitra Latsou, John Yfantopoulos
OBJECTIVE: To estimate the impact of hypoglycemia on the Quality of Life (QoL) and its prevalence in patients with type 2 diabetes mellitus (T2DM) in Greece. DESIGN: A cross-sectional epidemiological study was conducted in 6631 patients with T2DM …
The use of recombinant human thyrotropin (Thyrogen) in the diagnosis and treatment of thyroid cancer
Leonidas H. Duntas, Nikolaos Tsakalakos, Brigitte Grab-Duntas, Maria Kalarritou, Elli Papadodima
The introduction of human recombinant thyrotropin (rhTSH/Thyrogen) into the diagnosis of thyroid cancer has substantially ameliorated the patient’s quality of life through the avoidance of debilitating hypothyroidism. With the aim of updating the use of Thyrogen, we report 7 cases which were treated with Thyrogen for diagnostic or therapeutic purposes …
Environmental chemicals targeting thyroid
Thomas R. Zoeller
Thyroid hormones (THs) are required for normal brain and somatic development and for the proper regulation of physiology in both children and adults. Thyroid function is controlled by the dynamic interrelationships between the hypothalamus, the pituitary and the thyroid. These dynamic relationships maintain circulating levels of THs …

Gerasimos P. Sykiotis, Argyro Sgourou, Adamantia Papachatzopoulou, Kostas B. Markou, Venetsana Kyriazopoulou, Athanasios G. Papavassiliou, Apostolos G. Vagenakis, Neoklis A. Georgopoulos
Thyrotropin (TSH) is the prime regulator of thyroid cell growth and function and acts through the thyrotropin receptor (TSHR) located on the surface membrane of thyrocytes. Somatic heterozygous mutations that cause TSHR activation in the absence of TSH have been found in toxic adenomas and in hot nodules of multinodular goiters…

Artemis Karkanaki, Dimitrios Vavilis, Alexandros Traianos, Ioannis Kalogiannidis, Dimitrios Panidis
Women present an estradiol-dependent cardiovascular risk profile. Based on various studies, it was considered that estrogen therapy (ET) in postmenopausal women could probably reduce the higher cardiovascular risk in this group. Assymetric dimethylarginine (ADMA) is an endogenous methylated arginine which inhibits nitric oxide ..
