Objective: It is well-established that hyperthyroidism of Graves disease is caused by generation of TSH-receptor stimulating autoantibodies. However, in some patients TRAB titers may be in normal levels. The rate and the burden of TRAB negative disease vary between studies. In this study, we compared the clinical and laboratory parameters of 170 patients (85 TRAB positive and 85 TRAB negative) that were diagnosed to have Graves disease in our department....

Introduction: Thymic hyperplasia is a rare manifestation of Graves disease. In this report, we describe a female with Graves’ disease and a neck mass that was associated with thymic hyperplasia.Case report: A 28-year-old woman was referred to our division for the evaluation of palpitations. Thyroid function tests were associated with thyrotoxicosis. Thyroid receptor antibody (TRAb) was found to be 22.3 U/l (positive: >14 U/l). Sonography showed ...

The mechanism of atherosclerosis in patients with subclinical hypothyroidism (sHT), which has been partly attributed to lipid abnormalities, is still controversial. There is substantial evidence that ox-LDL plays an important role during the atherosclerosis process and paraoxonase-1 (PON-1) significantly inhibits generation of lipid peroxidation and thus plays a role in against atherosclerosis. The aim of the study was evaluate qualitative changes in lipoprotein metabolism, hs...

Various abnormalities of coagulation may occur in patients with thyroid disorders and may range from subclinical laboratory abnormalities to clinically significant disturbances of coagulation. Tissue factor pathway inhibitor (TFPI) is a newly determined potent inhibitor of tissue factor dependent coagulation system. TFPI changes in various thyroid disorders has not been evaluated yet. In this study we have evaluated total TFPI (tTFPI), free TFPI (fTFPI), tissue plasminogen act...

Fine needle aspiration biopsy is the cornerstone for cytologic evaluation of thyroid nodules. Thyroid nodule prevelance increases with age, however there is no cytologic study exclusively from geriatric patients.We examined the thyroid fine needle biopsy records taken from patients age 65 years or older between January 2006 and June 2009 at Dokuz Eylul University Hospital; and reviewed the cytological results of this group.We analy...

Objective: Endogenous hyperthyroidism is associated with altered coagulation. The aim of the present study is to investigate the effect of levothyroxine (LT4) suppression treatment for benign thyroid nodules on coagulation system.Design: Prospective case-control study.Patients: Thirty consecutive euthyroid pre-menopausal women with nodular goitre disease and 28 healthy controls were included in the study.Meas...

Thyroid dysfunction is associated with altered levels of several coagulation factors. The aim of this study is to investigate the effect of levothyroxine suppression therapy for benign thyroid nodules on coagulation system.Thirty-six patients with benign thyroid nodules, who were applicant for levothyroxine suppression therapy, were included in the study. Thirty patients completed 1 year follow-up period. Levothyroxine was given to maintain TSH level bet...

Aim: Non-alcoholic steatohepatitis is one of the most common causes of chronic liver disease and the incidence in the population varies from %10–24. TGF- β –1 is the most important TGF- β isoform responsible for fibrosis and its effect on hepatic fibrosis was demonstrated in-vitro and in chronic viral hepatitis. Besides TGF- β is an immunsuppresive cytokine and it is known that low TGF- β activity can trigger autoimmune diseases and inflammation.<...

Introduction: Whether subclinical hypothyroidism (SCH) is related to risk for cardiovascular disease is controversial. Inflammation and oxidation of lipoproteins play an important role in the progression and complications of atherosclerosis.Therefore we aimed to evaluate the plasma levels of thiobarbituric acid reactive substances (TBARS) as a marker of oxidative stress, high sensitive CRP (hsCRP) and lipid profile as a risk factor for atherosclerosis in...

Introduction: Although the etiology of osteoporosis is different between men and women, the underlying pathophysiologic mechanism is similar, namely an absolute or relative increase in bone resorption, leading to progressive bone loss. Transforming growth factor (TGF) beta-1 is a growth factor in human bone, which is produced by osteoblasts and inhibits osteoclast proliferation and activity and stimulates proliferation and differentiation of preosteoblasts.<p class="abstex...
