Variations in plasma free 25-hydroxyvitamin D concentrations during intermittent fasting are independently correlated with amino acid intake among meat and non-meat eaters

Karras Spyridon , Koufakis Theocharis , Adamidou Lilian , Dimakopoulos George , Melidou Eirini , Karalazou Paraskevi , Thisiadou Katerina , Zebekakis Pantelis , Makedou Kali , Kotsa Kalliopi

Background: Data on the effects of different dietary patterns on free 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) concentrations are scarce. Our objective was to prospectively assess changes over time in these parameters and possible correlations with diet composition among overweight adults who followed a pescatarian Orthodox intermittent fasting (OF) regimen and controls who followed a low-fat 12:12 diet for 7 weeks.Methods: Tota...

A comparative evaluation of late effects of Orthodox religious fasting vs time restricted eating on metabolic profiles of overweight adults

Karras Spyridon , Koufakis Theocharis , Adamidou Lilian , Grammatiki Maria , Polyzos Stergios , Karalazou Paraskevi , Thisiadou Katerina , Zebekakis Pantelis , Makedou Kali , Kotsa Kalliopi

Background: Previous research has demonstrated positive effects of Orthodox fasting (OF) and time restricted eating (TRE) on body weight (BW). However, little is known about the late, metabolic effects of the two diets.Methods: 29 overweight adults followed a hypocaloric diet based on OF. A hypocaloric, TRE plan (eating between 08:00 to 16:00 h) was followed by 16 BW-matched participants. Anthropometric, glycemic and inflammation markers and serum lipids...

Dapagliflozin and Atkins Diet in a patient with type 2 Diabetes Mellitus: A combination that should be avoided

Grammatiki Maria , Rapti Eleni , Dina Despina , Koufakis Theocharis , Antonopoulou Vasiliki , Tsekmekidou Xanthippi , Yavropoulou Maria , Karras Spyridon , Zebekakis Pantelis , Kotsa Kalliopi

Introduction: Prevalence of type 2 diabetes mellitus (T2DM) rises rapidly worldwide and most patients with T2DM are obese. All treatment algorithms advocate lifestyle modification and weight loss in combination with various therapeutic categories available for the treatment of T2DM, resulting in diet-antidiabetic drug combinations that are not always proper or safe for the patients.Case presentation: A 73-year-old Caucasian man presented to the emergency...

Association between clinical and genetic factors and glycemic and weight loss response to liraglutide in patients with type 2 diabetes

Kyriakidou Artemis , Kyriazou Angeliki V. , Koufakis Theocharis , Vasilopoulos Yiannis , Grammatiki Maria , Mellidou Eirini , RAKITZI PANTELITSA , Karaliolios Georgios , Goulis Dimitrios , Zebekakis Pantelis , Kotsa Kalliopi

Background: Previous research suggests an association between specific genetic variations and interindividual variability in response to treatment with glucagon-like receptor agonists (GLP-1 RAs) in patients with type 2 diabetes mellitus (T2DM). We aimed to evaluate the role of CTRB1/2 rs7202877 (T>G) polymorphism in glycemic control and weight loss response to liraglutide among Greek patients with T2DM and to identify clinical factors related to prediction of res...

Infection with the human immunodeficiency virus is characterized by a downregulation of the inverse relationship between irisin and parathyroid hormone independently of vitamin D status

Karras Spyridon , Koufakis Theocharis , Dimakopoulos George , Zisimopoulou Eleana , Mourampetzis Petros , Manthou Elena , Melidou Eirini , Karalazou Paraskevi , Thisiadou Katerina , Tsachouridou Olga , Zebekakis Pantelis , Makedou Kali , Metallidis Symeon , Kotsa Kalliopi

Background: Infection with the human immunodeficiency virus (HIV) predisposes to endocrine disorders, manifesting as a metabolic phenotype that affects the entire adipose-musculoskeletal unit (AMS). The present cross-sectional study aimed to investigate differences in irisin and adiponectin concentrations between people living with HIV and healthy controls, as well as to explore potential correlations between the levels of the aforementioned adipokines and markers of calcium h...

The effect of parathyroidectomy on glucose homeostasis and incretin hormone release in patients with primary hyperparathyroidism: a pilot study

Antonopoulou Vasiliki , Grammatiki Maria , Koufakis Theocharis , Karras Spyridon , Yavropoulou Maria , Katsiki Niki , Gerou Spyridon , Gavana Elpida , Skoura Lemonia , Zebekakis Pantelis , Papavramidis Theodosios , Kotsa Kalliopi

Background: Primary hyperparathyroidism (PHPT) has been linked to glucose homeostasis disorders, leading to insulin resistance and type 2 diabetes mellitus. Previous small studies evaluating the effect of parathyroidectomy (PTX) on various parameters of glucose metabolism have produced conflicting results. The impact of PTX on incretin hormone levels has not been studied yet. The aim of this pilot study was to investigate the effect of PTX on markers of glucose metabolism and ...

Effects of Orthodox fasting on cardiometabolic risk factors: a comparative evaluation between lay fasters and Athonian monks

Karras Spyridon , Koufakis Theocharis , Petróczi Andrea , Folkerts Dirk , Kypraiou Maria , Grammatiki Maria , Mulrooney Hilda , Naughton Declan , Skoutas Dimitrios , Adamidou Lilian , Zebekakis Pantelis , Kotsa Kalliopi

Background: Orthodox fasting (OF), a periodical vegetarian subset of the Mediterranean diet, has been shown to exert beneficial effects on human health. Athonian fasting is a pescetarian OF variation, where red meat is restricted throughout the year. Previous studies have examined the OF nutritional synthesis and health impact in general population fasters (GF) and Athonian monks (AM), separately. This is the first study to comparatively evaluate the characteristics and effect...

Association between variants in clock genes and type 2 diabetes in an elderly greek population

Background: Recent data suggest that disturbances in circadian clock functioning are implicated in the pathogenesis of type 2 diabetes (T2D), through alterations in plasma glucose levels, insulin secretion and sensitivity, energy intake, and genomic expression in liver and pancreas. This study aimed to assess a potential association between variants in clock genes and T2D risk in a population of Greek elderly people.Methods: In a case-control design, 125...

Assessment of association between VDR variants and type 2 diabetes in an elderly greek population

Tsekmekidou Xanthippi , Tsetsos Fotis , Koufakis Theocharis , Grammatiki Maria , Georgitsi Marianthi , Roumeliotis Athanasios , Panagoutsos Stylianos , Thodis Elias , Theodoridis Marios , Papanas Nikolaos , Papazoglou Dimitrios , Pasadakis Ploumis , Paschou Peristera , Zebekakis Pantelis , Kotsa Kalliopi

Background: Vitamin D receptor (VDR) in the presence of active calcitriol (1.25--dihydroxy vitamin D) acts as a transcription factor that modulates the gene expression oftransport proteins, which are involved in calcium metabolism. Accumulating evidence suggest apotential implication of vitamin D deficiency in the pathogenesis of diabetes mellitus. We aimed toassess whether variants in the VDR gene contribute to risk of Type 2 Diabetes Mellitus (T2DM).<p class="ab...
