Association of diabetes mellitus with thalassaemia and sickle cell disease

Thisiadou Katerina , Karamouzis Ioannis , Arampatzi Stella , Tomos Kostantinos , Michailidou Despoina

Background: The majority of complications in transfusion dependent thallasemic and with sickle cell anemia patients are due to iron overload. This is responsible for the beginning of haemosiderosis, clinical symptoms and dysfunction of important systems, specially after the 2nd decade of life. The increase of the iron accumulation is caused by hemolysis, high iron absorbance and mainly by transfusion treatment. The appearance of diabetes mellitus depends on the significance an...

Coagulation inhibitors in type 2 diabetes mellitus

Thisiadou Katerina , Karamouzis Ioannis , Arampatzi Stella , Lazaridou Despoina

Background: Diabetes mellitus (DM) is related to hypercoagulability.The predisposition for thrombosis disorders is caused by increased accumulation of platelets, by high concentrations of prothrombotic factors and by the reduced concentration and activity of the inhibitor factors. Abnormalities of coagulation inhibitors have been reported in many studies on diabetes over the last years, but unfortunately, the results have often appeared contradictory.</p...

Secondary hypoparathyroidism in thalassaemia and sickle cell anaemia

Thisiadou Katerina , Karamouzis Ioannis , Arampatzi Stella , Chalvatzi Kiriaki , Hasapopoulou Eleni , Michailidou Despoina

Background: The diagnosis of hypoparathyroidism, a clinical situation characterised by reduced production of parathyroid hormone despite the low calcium level, depends on patientÂ’s anamnesis, clinical aspect and the biochemical parameters.Thalassaemia, an inherited autosomal recessive blood disease, caused by the reduced capacity of erythroblasts to synthesize one of the chains that build up hemoglobine. The combination of transfusion and chelation ...

Abnormalities in calcium, phosphorus and parathyroid hormone in patients with end stage chronic kidney disease on hemodialysis

Thisiadou Katerina , Karamouzis Ioannis , Arampatzi Stella , Tsolakidou Alexandra , Sioulis Athanasios , Michailidou Despoina

Introduction: The decline of renal function is closely associated to increased parathyroid hormone secretion, resulting to secondary hyperparathyroidism because of: 1) hypocalcemia; 2) hyperphosphatemia; 3) reduced activity of calcitriol; 4) skeletal resistance to the calcemic action of parathyroid hormone (PTH) and 5) reduced secretion of the calcium-sensing receptor (CaSR) in the parathyroid glands.The retention of phosphorus is considered to take an i...

Effects of Christian Orthodox versus intermittent fasting on plasma irisin concentrations in overweight adults

Karras Spyridon , Koufakis Theocharis , Adamidou Lilian , Dimakopoulos Georgios , Karalazou Paraskevi , Thisiadou Katerina , Makedou Kali , Kotsa Kalliopi

Irisin is an adipomyokine produced during physical activity and implicated in the browning of adipose tissue. Existing evidence suggests an inverse relationship between irisin plasma levels and adverse metabolic outcomes; however, the exact impact of diet on irisin levels remains unclear. We aimed to assess the effects of two dietary patterns, Christian Orthodox fasting (OF) and 16:8 time-restricted eating (TRE), on irisin concentrations among overweight, metabolically healthy...

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...

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...

Sex-specific variations in lipid concentrations following a low-fat diet are mediated by vitamin D status: a 12-week prospective dietary intervention study among Christian Orthodox fasters

Karras Spyridon , Koufakis Theocharis , Adamidou Lilian , Dimakopoulos Georgios , Karalazou Paraskevi , Thisiadou Katerina , Bais Alkiviadis , Tzotzas Themistoklis , Makedou Kali , Manthou Eleni , Kotsa Kalliopi

BackgroundOrthodox religious fasting (OF) is a variation of the classical Mediterranean Diet during which meat and other animal products are restricted, whereas fish are occasionally and sea food are always allowed. The aim of this prospective study was to assess sex-specific differences in changes of lipid concentrations in a cohort of metabolically healthy adults following OF and investigate a potential role of vitamin D status in mediating these varia...
