Aim: Mean platelet volume (MPV) is considered a new indicator of atherosclerosis. Activated platelets and subclinical inflammation predispose to create for atherosclerotic heart disease. Larger platelets are metabolically more active than smaller ones and have more protrombotic potential. We have recently demonstrated that MPV levels in Hashimoto’s patients tend to be higher than healthy controls even if in euthyroid state. In present study we aimed to investigate a relat...

Aim: Thyroid hormones act both insulin agonistic and antagonistic in different organs. Studies that evaluate the relationship between insulin resistance and hypo-hyperthyroidism have conflicting results, even euthyroid status was shown to change insulin sensitivity. In this study, our aim is to investigate the association between TSH, free T4, free T3 levels and insulin resistance in euthyroid patients.Method: Euthyroid 57 males, 47...

Introduction: Thyroid disorders such as subacute thyroiditis occur rarely in pregnancy. We report a recurrent case of subacute thyroiditis improved with the onset of pregnancy.Case report: A 32-year-old Turkish women who request pregnancy and planned insemination was referred due to malaise and neck pain in the left side a week ago. She was presented with low-grade fever, fatigue, pharingitis symptoms, neck pain and extremely tenderness in the right side...

Aim: Nonenzymatic advanced glycation and oxidation end-products, advanced glycation end-products (AGEs), impart a potent impact on vessels in diabetic state and in euglycaemic conditions with increased oxidative stress.The aim of this study is to measure AGEs and its relationship with carotid intimae media thickness (CIMT) in acromegaly patients.Method: A case–control study was performed in 225 acromegalic patients (F/M: 116/1...

Aim: Paraoxonase-1 (PON-1), an HDL-associated enzyme has been shown to possess antioxidant properties that protect against atherosclerosis. The aim of this study is to evaluate serum paraoxanase activities, lipid profiles and carotid intimae media thickness (CIMT) as an early marker of atherosclerosis in healthy man and women.Method: Four hundred healthy volunteers (F/M: 250/150, 19–23 years) included in the study. Serum paraoxonase and arylesterase...

Growth hormon (GH) counteracts the effects of insulin on glucose metabolism and GH excess may lead to insulin resistance (IR). Impaired glucose tolerance (IGT) and diabetes mellitus (DM) are frequently associated with acromegaly. Microalbuminuria (MAU) is a well established cardiovascular (CV) risk factor and a predictor of CV mortality in both diabetic and nondiabetic subjects.The aim of this preliminary study was to investigate the MAU levels as a mark...

In new classification of autoimmune polyendocrine syndromes (APS), APS-3 has defined as combination of autoimmune thyroid disease and other autoimmune disease except hypoparathyroidism and Addison’s disease. The present report describes a patient with APS-3 and pseudomalapsorbtion of levothyroxine (LT4). Twenty-three year old woman was referred to our center with hypothyroidism due to Hashimoto’s thyroiditis (HT) despite the usage of high dose LT4 treatment. HT was d...

ApoB plays a central role in lipoprotein metabolism through regulation of total cholesterol and LDL-cholesterol (LDL-C) concentrations in plasma. Two restriction fragment length polymorphisms (ECoRI and XbaI) represent single base alterations in the coding region of ApoB gene. ECoRI polymorphic region of ApoB gene is due to on an amino acid change (Glu→Lys). The XbaI polymorphic region of ApoB gene results from a substitution of (A→T) in the threonine codon and doe...

Aim: Hypoadiponectinemia is known to be associated with insulin resistance, diabetes and obesity. Since gestational diabetes is together with increased body mass index (BMI) and decreased insulin sensitivity, the evaluation of adiponectin levels in these patients is interesting. We investigated the relationship between adiponectin and glucose tolerance during pregnancy and after delivery.Materials and methods: We evaluated plasma adiponectin levels, insu...

Recent studies indicate that atherosclerotic process is associated with bone metabolism. The aim of this study was to evaluate carotid intima media thickness (CIMT) and its association with bone mineral density and bone turnover markers as well as inflammation markers in type 2 diabetic male patients.Material-method: 184 type 2 diabetic males (56±8 y) and 85 non-diabetic control subjects (52±7 y) were recruited. Bone mineral density was measure...
