Comparison of the prediction powers of hypercalciuria tests for nephrolithiasis in patients with asymptomatic primary hyperparathyroidia

Ozkan Melek , Yener Serkan

Objective: One of the ways to predict nephrolithiasis, which is one of the surgical indications in patients with asymptomatic primary hyperparathyroidism, is to detect hypercalciuria. A calcium excretion of >400 mg/day in 24-hour urine, >4 mg/kg/day calcium excretion in 24-hour urine or a fractionated calcium excretion (FECa) >0.010 guide us in the detection of hypercalciuria and therefore nephrolithiasis. The aim of our study is which of these three tests is more ...

Effect of heterophilic antibody interference in ACTH immunoassay to Subclinical Cushing’s Syndrome screening: A pilot study

Yener Serkan , Ozisik Seciil , Cavdar Umit , Demirpence Mustafa , Comlekci Abdurrahman

Heterophilic antibodies are well-known interferent factors affecting most immunoassays. However, they have been poorly evaluated in routine clinical practice. Definition of Subclinical Cushing’s Syndrome (SCs) has been arbitrary and prevalence has shown significant variations related with the diversity of the diagnostic tests. In most of the guidelines a low or suppressed corticothropin (ACTH) level has been suggested as an important predictor of SCs. Here, we sought to i...

Liver manifestation of poorly controlled Type 1 diabetes mellitus: hepatic glycogenosis

Yener Serkan , Ozer Erdener , Yuce Ozlem , Bayraktar Firat , Yesil Sena

We report an 18 years old female with hepatomegaly and elevated liver function tests. She had been diagnosed with Type 1 diabetes mellitus when she was 13 years old. She was referred to our division because of diabetic ketoacidosis. Evaluation of her previous records revealed the presence of liver function abnormalities for 4 months. At physical examination she had an enlarged liver. A1c level was 13%. She was treated initially with intravenous insulin. Following the achieveme...

Mean platelet volume in women with previous gestational diabetes and its alteration during pregnancy

Celtik Aygul , Akinci Baris , Demir Tevfik , Yener Serkan , Yesil Sena

Previous gestational diabetes mellitus (pGDM) is associated with insulin resistance which is a well-known risk factor for atherosclerotic diseases. Mean platelet volume (MPV) is an indicator of platelet activation which plays a crucial role in pathogenesis of atherosclerosis.One hundred and five consecutive women with pGDM and 40 healthy women with normal previous pregnancies were included in the study. At the time of enrollment, anthropometric measureme...

Prediction of developing metabolic syndrome after gestational diabetes mellitus

Akinci Baris , Celtik Aygul , Yener Serkan , Yesil Sena

It has been shown that women with previous GDM more likely developed metabolic syndrome (MS). This study aimed to determine predictors of the later development of MS in women with previous GDM.One hundred sixty-four consecutive women with previous GDM were evaluated after a mean follow-up of 40.54 months from index pregnancy. Sixty-five lean women with negative screening for GDM were included as a control group. Data regarding antenatal and peripartum ch...

Acquired Fanconi syndrome and hypophosphatemic osteomalacia in two patients treated with adefovir and tenofovir

Saydam Basak Ozgen , Bengi Goksel , Yener Serkan , Comlekci Abdurrahman

Background: Proximal tubule dysfunction in Fanconi syndrome causes impaired reabsorbtion of amino acids, glucose, urate and phosphate, which leads to hypophosphatemic osteomalcia. Adefovir and tenofovir are two nucleoside reverse transcriptase inhibitors, which are used for treatment of patients with hepatitis B infection. Although these drugs are well tolerated with few side effects, patients may rarely suffer from drug-induced Fanconi syndrome and hypophosphatemic osteomalac...

Adenoma size could be an important predictor of Subclinical Cushing’s Syndrome

Yener Serkan , Baris Mustafa , Demirpence Mustafa , Ozisik Secil , Cavdar Umit , Demir Omer , Secil Mustafa , Comlekci Abdurrahman

Subclinical Cushing’s syndrome (SCs) is used to refer to an adrenal incidentaloma with subtle autonomous cortisol secretion and without typical signs and symptoms of hypercortisolism. Diagnostic criteria are uncertain and arbitrary. In this study we aimed to investigate the power of adenoma size as an independent predictor of SCs.Dokuz Eylul University Adrenal Tumours Study Group database includes 596 patients by January 2016. Briefly, there are 332...

Prospective evaluation of cardiovascular risk in subclinical Cushing's syndrome

Yener Serkan , Cekdemir Yasin , Baris Mustafa , Demirpence Mustafa , Demir Tevfik , Secil Mustafa

Introduction: Natural history of adrenal incidentalomas has not been totally understood. Current data from subjects with adrenal incidentalomas demonstrated an increased rate of metabolic disturbances and cardiovascular risk. It has been shown that subjects with subclinical cortisol excess were more susceptible to diabetes, hypertension, and obesity. However, there is no data regarding prospective cardiovascular risk evaluation in subjects with subclinical Cushing’s syndr...

Prevalance of cancer in acromegaly patients; a single center data

Gedik Arzu , Yilmaz Merve , Demir Tevfik , Yener Serkan , Bayraktar Firat , Eraslan Sevinc , Comlekci Abdurrahman

Introduction: The growth promoting effects of GH and IGF1 has lead to increasing number of cancer surveillence studies in acromegaly so far. We herein aimed to present the prevalance of cancer in acromegaly patients followed in our institution.Patients and design: We retrospectively analyzed medical records of 151 patients with acromegaly (83 females) followed in our department from 2001 to 2012.Results: Overall, cancer was detecte...

IL-6 and osteoprotogerin levels in subjects with non-functioning adrenal adenomas

Yener Serkan , Comlekci Abdurrahman , Yuksel Faize , Comlekci Abdurrahman , Akinci Baris , Demir Tevfik , Yesil Sena

Data regarding cardiovascular risk in subjects with non-functioning adrenal adenoma is limited. The aim of this study is to investigate osteoprotogerin (OPG) and Interleukin-6 (IL-6) levels in subjects with non functioning adrenal incidentalomas.Of 51 subjects without findings of hypercortisolism or other adrenal gland disorders (AI), 32 BMI-unmatched controls (C) and 20 BMI-matched controls (BC) were enrolled. Participants underwent hormonal evaluation ...
