Ates Ihsan , Altay Mustafa , Yilmaz Fatma Meric , Topcuoglu Canan , Neselioglu Salim , Erel Ozcan , Yilmaz Nisbet

Objective: To investigate dynamic thiol/disulphide homeostasis in autoimmune subclinical hypothyroidism.Materials and methods: 48 patients with newly diagnosed subclinical hypothyroidism due to Hashimoto’s thyroiditis and not yet on any treatment and 48 healthy subjects without any known disease were enrolled. Thiol/disulfide homeostasis (native thiol(-SH)–disulphide(-S-S-) exchanges) was measured in both groups with new method developed by Ere...

Is oxidative stress an effective risk factor in the development of overt hypothyroidism in Hashimoto's thyroiditis?

Ates Ihsan , Altay Mustafa , Yilmaz Fatma Meric , Topcuoglu Canan , Yilmaz Nisbet , Guler Serdar

Objective: We aimed to investigate the effects of oxidative stress in the pathhogenesis and progression of thyroiditis in patients with Hashimoto’s thyroiditis whose aetiopathogenesis includes environmental and genetic factors.Methods: 80 patients (40 euthyroid and 40 subclinical hypothyroidism) older than 18 years with newly diagnosed Hashimoto’s thyroiditis and not yet on any treatment were enrolled. Patients were followed up for 9 months. Bl...

Does treatment with levothyroxine sodium decrease oxidative stress in Hashimoto's thyroiditis?

Ates Ihsan , Altay Mustafa , Yilmaz Fatma Meric , Yilmaz Nisbet , Guler Serdar

Background: In Hashimoto’s thyroiditis, chronic inflammation and autoimmunity increases oxidant radicals and cause oxidative stress. However, the effect of levothyroxine therapy on the oxidant and antioxidant systems is not known in overt hypothyroidism. Therefore, we sought to investigate the effect of levothyroxine sodium therapy on oxidative stress in patients with Hashimoto thyroiditis and overt hypothyroidism.Materials and methods: 36 patients ...

The role of circulating sTWEAK in the pathogenesis of Hashimoto's thyroiditis and its relationship with other cytokines: a pilot study

Altay Mustafa , Ates Ihsan , Yilmaz Fatma Meric , Topcuoclu Canan , Kaplan Mustafa , Altay Fatma Aybala

Objective: We aimed to investigate the role of sTWEAK in the pathogenesis of Hashimoto’s Thyroiditis (HT) and its relationship with IL-12, IL 17-A and TGF-β1.Methods: Serum TSH, FT4, anti-TG and anti-TPO were measured and thyroid USG was performed to both group. In addition serum samples were collected and sTWEAK, IL 17-A, IL-12 and TGF-β1 were measured.Patients: Six patients (20 patients were euthyroid, 2...

The impact of levothyroxine sodium treatment on dynamic thiol/disulphide homeostasis in overt hypothyroidism

Bicer Cemile , Ates Ihsan , Aydin Murat , Altay Mustafa , Topcuoglu Canan , Neselioglu Salim , Erel Ozcan , Yilmaz Fatma Meric

Objective: Thiols are organic compounds that contain sulphydryl group (-SH) and have important role in preventing oxidative stress especially in cells. The aim of our study is to investigate the relationship between hypothyroidism due to HT and the thiol disulfide homeostasis, the effect of treatment on this homeostasis and to demonstrate the utility of thiol/disulphide homestasis as a marker for assessing the damage to functional group of proteins and the oxidative balance in...

Dynamic thiol/disulfide homeostasis in patients with newly diagnosed type 2 diabetes mellitus

Bayrakci Nergiz , Ates Ihsan , Ozkayar Nihal , Yilmaz Fatma Meric , Topcuoglu Canan , Neselioglu Salim , Erel Ozcan , Altay Mustafa

Background: Thiol/disulfide homeostasis plays an important role in antioxidative defense mechanism, detoxification, signal transport, management of enzyme activity and trascription factors, and apoptosis. When thiol/disulphide homeostasis breaks down, these important cellular functions get deranged. Pathologies secondary to oxidative stress are seen in organeles in which this homeostasis is deranged. The aim of the study was to investigate dynamic thiol/disulfide homeostasis i...

Evaluation of adipocytokine levels and vascular reactivity in hypogonadotropic hypogonadal males

Tuna Mazhar Muslum , Dogan Bercem Aycicek , Karakilic Ersen , Isik Serhat , Yilmaz Fatma Meric , Topcuoglu Canan , Berker Dilek , Guler Serdar

Introduction: Hypogonadism have major affect on urogenital system also have several affect on other systems like cardiovascular and skeletal systems. There are very few study conducted on markers of atherosclerosis such as flow mediated dilatation (%FMD), carotis intima-media thickness(CIMT) and adipocytokine levels in idiopatic hypogonadotropic hypogonadal(IHH) males. The aim of this study was to evaluate this atherosclerotic risk factors in adult IHH male.<p class="abste...
