Background It is well documented that patients with chronic metabolic diseases, such as diabetes and obesity, are adversely affected by the COVID-19 pandemic. However, when the subject is rare metabolic diseases, there are not enough data in the literature. Aim To investigate the course of COVID-19 among patients with Gaucher disease (GD), the most common lysosomal storage disease. Methods Based on the National Health System data, a retrospective cohort of patients with confirmed (polymerase chain reactionpositive) COVID-19 infection (n = 149 618) was investigated. The adverse outcomes between patients with GD (n = 39) and those without GD (n = 149 579) were compared with crude and propensity score-matched (PSM) groups. The outcomes were hospitalisation, the composite of intensive care unit (ICU) admission and/or mechanical ventilation and mortality. Results The patients with GD were significantly older and had a higher frequency of hypertension (HT), Type 2 diabetes mellitus (T2DM), dyslipidaemia, asthma or chronic obstructive pulmonary disease, chronic kidney disease, coronary artery disease, heart failure and cancer. Although hospitalisation rates in Gaucher patients were found to be higher in crude analyses, the PSM models (model 1, age and gender matched; model 2, matched for age, gender, HT, T2DM and cancer) revealed no difference for the outcomes between patients with GD and the general population. According to multivariate regression analyses, having a diagnosis of GD was not a significant predictor for hospitalisation (P = 0.241), ICU admission/mechanical ventilation (P = 0.403) or mortality (P = 0.231). Conclusion According to our national data, SARS-CoV-2 infection in patients with GD does not have a more severe course than the normal population.

Purpose While obesity is related to more severe outcomes of coronavirus disease 2019 (COVID-19), factors leading to poor prognosis still remain unclear. The present study evaluated the outcomes of COVID-19 patients who were overweight or obese and variables associated with severe disease in a large group of consecutive cases. Methods A nationwide retrospective cohort study was performed using the Turkish National Healthcare Database. Demographic characteristics, laboratory tests, comorbidities, and medications of patients registered between March 11 and May 30, 2020, were recorded. Results A total of 14, 625 patients (median age:42, IQR:26 years; female 57.4%) with normal weight (34.7%), overweight (35.6%), and obesity (29.7%) were included. Hospitalization, ICU admission, intubation/mechanical ventilation, pulmonary involvement, and mortality were significantly higher in patients who were overweight or obese. In adjusted analyses, both overweight (OR, 95% CI: 1.82, 1.04–3.21; p=0.037) and obesity (OR, 95% CI: 2.69, 1.02–1.05; p Conclusions COVID-19 patients who were overweight or obese were more likely to have adverse outcomes but only obesity was a predictor of mortality. Such patients should receive urgent medical attention and active management, especially the elderly, men, and people with chronic kidney disease.

Purpose New coronavirus disease 2019 (COVID-19) has a worse prognosis in patients with diabetes. However, there are insufficient data about the effect of hyperglycemia on COVID-19 prognosis in non-diabetic patients. This study aimed to investigate the relationship between random blood glucose levels measured at the time of diagnosis and prognosis of COVID-19 disease in non-diabetic patients. Methods A nationwide retrospective cohort of non-diabetic patients with confirmed COVID-19 infection from 11 March to 30 May 2020 in the Turkish Ministry of Health database was investigated. The patients were stratified into three groups according to blood glucose levels which were Results A total of 12,817 non-diabetic patients (median age [IQR]: 44 [25] years, females: 50.9%) were included. Patients in group-2 (5%) and group-3 (14%) had higher mortality rates than patients in group-1 (2.1%). The rates of hospitalization, hospital stays longer than 8 days, intensive care unit (ICU) admission, ICU stay more than 6 days, and mechanical ventilation were also significantly higher in group-3 patients. Likewise, glucose levels in the range of 140-199 mg/dL were an independent associate of mortality and composite of ICU admission and/or mechanical ventilation. ConclusionHyperglycemia at the time of COVID-19 diagnosis is associated with poor prognosis in non-diabetic patients. Clinicians should be more careful in the treatment of non-diabetic COVID-19 patients with hyperglycemia.

The influence of chronic lymphocytic thyroiditis (CLT) on clinicopathological features and behavior of differentiated thyroid carcinoma (DTC) is still debated. In the present study, we aimed to evaluate the prognosis of DTC on the presence of CLT. A total of 649 total thyroidectomized patients (379 female, 270 male) with DTC, who had follow-up data for at least 36 months were included. Clinical, histopathological data, preoperative thyroid peroxidase antibody (TPO-ab), thyroglobulin antibody (Tg-ab), thyroid-stimulating hormone (TSH) levels, and presence of recurrent/persistent disease (R/PD) were evaluated retrospectively. Presence of CLT was defined by histopathology. Frequency of CLT was 32% (n = 208) among DTC patients. Mean tumor size (maximal diameter) was smaller in CLT group when compared to non-CLTs (p = 0.006). Capsular invasion, vascular invasion, tumor stage, risk groups, and R/PD were negatively associated with CLT (p

Introduction Incidental thyroid cancers are frequently detected in patients operated on for Graves' disease (GD). There are no clear data about the incidence and risk factors of incidental thyroid cancer in operated GD patients. The aim of this study is to evaluate the risk of thyroid carcinoma in surgically treated GD patients. Material and methods The data of 121 GD patients who underwent total thyroidectomy in a single center between 2005 and 2015 were retrospectively evaluated. The diagnosis of thyroid cancer was based on pathological examination. Results Thyroid cancer was demonstrated in postoperative pathology specimens of 34 patients who were surgically treated for GD (28.1%). Preoperative thyroid ultrasonography (USG) revealed a nodular goiter in 62 (51.2%) patients. Nodules were not detected in the other 59 (48.8%) patients with GD. The frequency of thyroid cancer was significantly higher in patients with nodules (38% vs. 16%; p = 0.009). Thirty-two of the 34 cancer cases had papillary thyroid cancer (PTC), and the remaining 2 had follicular thyroid cancer (FTC). Of the 32 PTC patients, 28 were classical type, 2 patients had the follicular variant, 1 was the oncocytic variant, and 1 was a tall cell variant. Conclusions The incidence of thyroid cancer was higher in patients who underwent surgery for GD. In addition to a careful physical examination in the follow-up of the patients with GD, ultrasonographic evaluation should be performed. Surgical treatment should not be delayed in patients with GD when indicated.

PurposeCOVID-19 disease has a worse prognosis in patients with diabetes, but the comparative data about the course of COVID-19 in patients with type 1 (T1DM) and type 2 diabetes (T2DM) are lacking. The purpose of this study was to find out the relative clinical severity and mortality of COVID-19 patients with T1DM and T2DM.MethodsA nationwide retrospective cohort of patients with confirmed (PCR positive) COVID-19 infection (n=149,671) was investigated. After exclusion of individuals with unspecified diabetes status, the adverse outcomes between patients with T1DM (n=163), T2DM (n=33,478) and the non-diabetics (n=115,108) were compared by using the propensity score matching method. The outcomes were hospitalization, the composite of intensive care unit (ICU) admission and/or mechanical ventilation and mortality.ResultsThe patients with T1DM had higher mortality than the age and gender matched patients with T2DM (n=489) and the non-diabetics (n=489) (pConclusionAccording to the results, patients with T1DM had poorer COVID-19 prognosis than those with T2DM or the non-diabetics. These patients should be cared diligently until more data will be available about the causes of increased COVID-19 mortality in T1DM.

Objective: To directly compare the efficacy and safety of a fixed-ratio combination, iGlarLixi, with a premix insulin analog (BIAsp 30) as treatment advancement in type 2 diabetes suboptimally controlled on basal insulin plus oral antihyperglycemic drugs (OADs). Research Design and Methods: SoliMix, a 26-week, open-label, multicenter study, randomized adults with suboptimally controlled basal insulin-treated type 2 diabetes (HbA1c ≥7.5 % and ≤10 %) to once-daily iGlarLixi or twice-daily BIAsp 30. Primary efficacy endpoints were non-inferiority in HbA1c reduction (margin 0.3 %) or superiority in bodyweight change for iGlarLixi versus BIAsp 30. Results: Both primary efficacy endpoints were met: after 26 weeks, baseline HbA1c (8.6 %) was reduced by 1.3 % with iGlarLixi and 1.1 % with BIAsp 30, meeting non-inferiority (least squares [LS] mean difference [97.5% CI]: -0.2 [-0.4, -0.1] %; p1c 1c 1c reduction (p Conclusions: Once-daily iGlarLixi provided better glycemic control with weight benefit and less hypoglycemia than twice-daily premix BIAsp 30. iGlarLixi is a more efficacious, simpler, and well-tolerated alternative to premix BIAsp 30 in suboptimally controlled type 2 diabetes requiring treatment beyond basal insulin plus OAD therapy.

Introduction: iGlarLixi, a fixed-ratio combination of insulin glargine 100 U/mL and lixisenatide, offers an alternative treatment advancement option to premix insulin for uncontrolled basal insulin-treated T2D. SoliMix, an open-label, multicenter study, was the first to compare these two insulin coformulations. Methods: SoliMix randomized adults with T2D and HbA1c ≥7.5-≤10 % on basal insulin + oral antihyperglycemic drugs (OADs) to once-daily iGlarLixi or twice-daily premix insulin 70/30 analogue (BiAsp 70/30). Co-primary efficacy endpoints were non-inferiority in HbA­1c reduction or superiority in bodyweight change from baseline to Week 26 of iGlarLixi vs. BiAsp 70/30. Results: Both co-primary efficacy endpoints were met (Table), as well as iGlarLixi superiority vs. BiAsp 70/30 in HbA1c reduction. Significantly more participants reached HbA1c Conclusions: Based on better glucose control with weight benefit and less hypoglycemia, once-daily iGlarLixi is a favorable alternative to twice-daily premix 70/30 for advancing therapy in people with T2D uncontrolled on basal insulin + OADs.

This study was designed to detect the potential association of a nonfunctional adrenal incidentaloma (NFAI) with insulin resistance and associated metabolic disturbances, with a subsequent increase in cardiovascular risk factors.Eighty-three NFAI patients and 56 volunteers (controls) without any adrenal abnormalities on computed tomography (CT) were included. Fasting blood glucose (FBG), fasting insulin, lipid profiles, uric acid, homocysteine, fibrinogen, high sensitivity C-reactive protein (hs-CRP), and adiponectin levels were measured in both groups. Blood pressure (BP), waist circumference, body mass index (BMI), and carotid intima media thickness (CIMT) were evaluated in both the patients and volunteers.There were no significant difference between the NFAI and control groups with respect to age, sex, BMI, waist circumference, systolic and diastolic BP, smoking, concomitant disease, and medications. Fasting insulin and glucose levels and homeostasis model of assessment-insulin resistance (HOMA-IR) scores were significantly higher in the NFAI group as compared with those in the control group (p0.01). The frequency of metabolic syndrome in the NFAI group was higher than that in the control group (p0.01). All the lipid fractions, except triglyceride (TG), (p0.05), homocysteine (p=0.01), and fibrinogen levels (p0.001), were significantly higher in the NFAI group as compared with the levels in the control group. There were no significant differences between the NFAI and control groups in terms of uric acid, hs-CRP, and adiponectin levels. The CIMT values in the NFAI group were significantly higher than those in the control group (0.74±0.14 vs. 0.53±0.09, p0.001). The mean CIMT value showed a statistically positive correlation with age (r=0.245, p=0.004); the HOMA-IR score (r=0.490, p0.001); and FBG (r=0.521, p0.001), fasting insulin (r=0.432, p0.001), total cholesterol (TC) (r=0.267, p=0.002), and fibrinogen (r=0.398, p0.001) levels in the NFAI group.The results indicated that the NFAI patients had an elevated risk of insulin resistance, with metabolic syndrome and increased CIMT values. Long-term follow-up studies should be designed to evaluate postsurgical alterations in metabolic parameters and cardiovascular risk factors in NFAI patients.

BACKGROUND Diagnostic accuracy of fine-needle aspiration cytology (FNAC) in large and subcentimeter nodules is still debated. We aimed to evaluate the impact of nodule size on efficacy of the ultrasound-guided FNAC. METHODS B-mode grayscale ultrasound (US), US-guided FNAC according to Bethesda system and histopathological data of 514 nodules from 371 patients, who underwent thyroidectomy were examined retrospectively. Nodules were grouped by maximal diameter; group A nodules were smaller than 10 mm (n = 59), group B nodules were between 10 and 29 mm (n = 218), and group C nodules were 30 mm or greater (n = 130). RESULTS Sensitivity, specificity, and accuracy of FNAC was 92.0%, 100%, and 95.1% in group A, 80.7%, 99.1%, and %92.9 in group B, 70.0%, 98.9%, and 95.8% in group C nodules, respectively. The prevalence of papillary thyroid cancer (PTC) and incidental PTC were 44.2% (n = 164) and 6.4% (n = 24), respectively. Malignancy rate was more frequent in group A when compared to groups B and C (P

OBJECTIVES Although metabolically healthy obesity (MHO) has begun to be seen as a being benign phenomenon, this conclusion is still not completely certain. Obesity is also associated with low-grade systemic inflammation and endothelial dysfunction. Thus, we aimed to assess Pulse Wave Velocity (PWV) as a marker of arterial stiffness and CV risk among individuals with MHO, metabolically unhealthy obesity (MUO), and metabolically healthy normal-weight (MHN). METHODS 150 participants (n = 50 MHO, n = 50 MUO, n = 50 MHN) who had been admitted to our outpatient clinics were enrolled in this cross-sectional study. Demographic, anthropometric, clinical, and laboratory data, including hs-CRP and PWV, were recorded for all subjects. RESULTS hs-CRP and PWV were higher in MUO and MHO than MHN individuals (P

Background Coronavirus disease 2019 (COVID‐19) has been reported to be associated with a more severe course in patients with type 2 diabetes mellitus (T2DM). However, severe adverse outcomes are not recorded in all patients. In this study, we assessed disease outcomes in patients with and without T2DM hospitalized for COVID‐19. Methods A nationwide retrospective cohort of patients with T2DM hospitalized with confirmed COVID‐19 infection from 11 March to 30 May 2020 in the Turkish Ministry of Health database was investigated. Multivariate modeling was used to assess the independent predictors of demographic and clinical characteristics with mortality, length of hospital stay, and intensive care unit (ICU) admission and/or mechanical ventilation. Results A total of 18 426 inpatients (median age [interquartile range, IQR]: 61 [17] years; males: 43.3%) were investigated. Patients with T2DM (n = 9213) were compared with a group without diabetes (n = 9213) that were matched using the propensity scores for age and gender. Compared with the group without T2DM, 30‐day mortality following hospitalization was higher in patients with T2DM (13.6% vs 8.7%; hazard ratio 1.75; 95% CI, 1.58‐1.93; P, Highlights Coronavirus disease 2019 (COVID‐19) takes an unfavorable course in patients with type 2 diabetes mellitus (T2DM), and the risk increases in individuals with certain conditions, some of which are not modifiable.This study showed significantly higher mortality due to COVID‐19 in hospitalized patients with T2DM than without (13.6% vs 8.7%; hazard ratio 1.75; 95% CI, 1.58‐1.93).Older age, male gender, obesity, preexisting insulin treatment, low lymphocyte count, and pulmonary involvement on admission were the significant associates of COVID‐19 mortality.

OBJECTIVE To directly compare the efficacy and safety of a fixed-ratio combination, of insulin glargine 100 units/mL and the glucagon-like peptide 1 receptor agonist lixisenatide (iGlarLixi), with those of a premix insulin analog, biphasic aspart insulin 30 (30% insulin aspart and 70% insulin aspart protamine) (BIAsp 30) as treatment advancement in type 2 diabetes suboptimally controlled on basal insulin plus oral antihyperglycemic drugs (OADs). RESEARCH DESIGN AND METHODS In SoliMix, a 26-week, open-label, multicenter study, adults with suboptimally controlled basal insulin–treated type 2 diabetes (HbA1c ≥7.5% and ≤10%) were randomized to once-daily iGlarLixi or twice-daily BIAsp 30. Primary efficacy end points were noninferiority in HbA1c reduction (margin 0.3%) or superiority in body weight change for iGlarLixi versus BIAsp 30. RESULTS Both primary efficacy end points were met: after 26 weeks, baseline HbA1c (8.6%) was reduced by 1.3% with iGlarLixi and 1.1% with BIAsp 30, meeting noninferiority (least squares [LS] mean difference −0.2% [97.5% CI −0.4, −0.1]; P < 0.001). iGlarLixi was also superior to BIAsp 30 for body weight change (LS mean difference −1.9 kg [95% CI −2.3, −1.4]) and percentage of participants achieving HbA1c CONCLUSIONS Once-daily iGlarLixi provided better glycemic control with weight benefit and less hypoglycemia than twice-daily premix BIAsp 30. iGlarLixi is a more efficacious, simpler, and well-tolerated alternative to premix BIAsp 30 in suboptimally controlled type 2 diabetes requiring treatment beyond basal insulin plus OAD therapy.

Aim Premix insulin is commonly used in some regions of the world, despite the higher risk of hypoglycaemia and weight gain compared with basal insulin, based on the premise that it offers a simplified insulin regimen. iGlarLixi is a once-daily titratable fixed-ratio formulation that combines basal insulin glargine 100 units/mL (iGlar) and the GLP-1 RA, lixisenatide, which offers a single-injection option for treatment intensification, with improved HbA1c reductions, similar hypoglycaemia risk and more favourable bodyweight profiles over iGlar alone. This randomized controlled study directly compares, for the first time, treatment intensification with iGlarLixi versus premix insulin analogue biphasic insulin aspart 30 (BIAsp 30) in adults with T2D inadequately controlled on basal insulin in combination with one or two oral antihyperglycaemic drugs. Materials and methods This was an open-label, active-controlled, comparative, parallel-group, multicentre, phase 3b study. In total, 887 adults with T2D uncontrolled on basal insulin were randomized to switch to either iGlarLixi once daily, or BIAsp 30 twice daily, for 26 weeks. Results Overall, 887 participants were enrolled (mean age 59.8 years, 50.2% female) from 89 centres in 17 countries. At baseline, 65.6% had a duration of T2D of 10 years or longer, and the mean HbA1c at baseline was 8.6%. Conclusions The study directly compared the efficacy and safety of iGlarLixi versus BIAsp 30 in people with T2D uncontrolled on basal insulin and one or more oral antihyperglycaemic agents. These results provide robust clinical data that may inform clinicians in their therapeutic management of people with T2D uncontrolled on basal insulin requiring additional therapy.

Aim To investigate the effectiveness of premixed insulin for achieving glycaemic outcomes in clinical practice in the UK. Materials and Methods Electronic medical record data from The Health Improvement Network database were captured for adults with type 2 diabetes (T2D) uncontrolled (HbA1c ≥9%) on two or more oral antihyperglycaemic drugs (OADs) initiating premixed insulin. Effectiveness of premixed insulin was assessed by the probability and incidence of achieving glycaemic outcomes (target HbA1c 40 kg/m2 and co‐morbidities including nephropathy and stroke. Conclusions In people with uncontrolled T2D (HbA1c ≥9%), glycaemic outcome achievement on premixed insulin was low at 6 months with little additional clinical benefit beyond 12 months, suggesting a high unmet need for early, timely treatment changes with more effective, simpler therapies.

NICE guidelines suggest premix as a treatment option for people with T2D with HbA1c ≥9 % uncontrolled by ≥2 oral antidiabetic drugs (OADs). This retrospective cohort study explored real-world evidence for glycemic control with premix. UK electronic medical record data from THIN database were captured for adults with T2D uncontrolled (HbA1c ≥9 %) on ≥2 OADs initiating premix (index date) from 1/1/2010 to 12/31/2016. Baseline data were collected 12 months pre-index and outcomes followed for 24 months. Glycemic control was assessed by time to first achievement of HbA1c target Disclosure E.B.

Objectives: To describe biochemical and clinical features, and therapeutic outcomes of acromegaly patients in Turkey. Methods: Retrospective multicenter epidemiological study of 547 patients followed in 10 centers of the Turkish Acromegaly registry. Results: A total of 547 acromegaly patients (55% female) with a median age of 41 was included in this study. Majority of patients had a macroadenoma (78%). Transsphenoidal surgery was performed as primary treatment in 92% of the patients (n = 503). Surgical remission rate was 39% (197/503) in all operated patients. Overall disease control was achieved in 70% of patients. Remission group were significantly older than non-remission group (p = .002). Patients with microadenomas had significantly higher remission rates than patients with macroadenomas (p < .001). Patients with microadenomas were significantly older at the time of diagnosis when compared to patients with macroadenomas (p < .001). Preoperative growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were significantly lower in the remission group (p < .001). Initial IGF-1 and GH levels were significantly higher in macroadenomas compared to microadenomas (p < .001). Medical treatment was administered as a second-line treatment (97%) in almost all patients without remission. Radiotherapy was preferred in 21% of the patients mostly as a third line treatment. Conclusions: This is one of the largest real life studies evaluating the epidemiological characteristics and treatment outcomes of patients with acromegaly who were followed in different centers in Turkey. Transsphenoidal surgery in the treatment of acromegaly still remains the most valid method. Medical treatment options may improve long-term disease outcomes in patients who cannot be controlled with surgical treatment (up to 70%).

Aim The aim of this study was to determine the role of fluorine-18-choline (F-FCH) PET/CT in comparison with technetium-99m-methoxyisobutylisonitrile (Tc-MIBI) single-photon emission computed tomography/computed tomography (SPECT/CT) in primary hyperparathyroidism and to investigate whether maximum standardized uptake value (SUVmax) may be indicative of disease severity. Patients and methods Thirty-five primary hyperparathyroidism patients (24 females, 11 males, mean age: 55.31±12.27, range: 25-72 years) who underwent Tc-MIBI SPECT/CT and F-FCH PET/CT and had inconclusive neck ultrasonography (USG) were studied. The diagnostic power of both modalities and the relationship between SUVmax and biochemical [serum parathormone (PTH), calcium, phosphorus, vitamin D3 levels, urinary calcium excretion/24 h] and clinical (bone mineral densitometry and urinary USG results) parameters were analyzed. Results In 29 of 35 patients, Tc-MIBI SPECT/CT and F-FCH were concordant (κ=0.64, P=0.001). In five of 35 patients with a negative SPECT/CT, F-FCH PET/CT accurately localized parathyroid adenomas. In one patient, F-FCH was false negative and Tc-MIBI SPECT/CT showed the lesion. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of Tc-MIBI SPECT/CT and F-FCH PET/CT were calculated to be 78, 100, 100, 70, 86%, and 96, 100, 100, 93, and 97%, respectively. SUVmax was correlated with lumbal T scores (P=0.026). The mean serum PTH levels were significantly higher (P=0.026) and lumbal and femur T scores were significantly lower (P=0.04 and 0.008) in patients with SUVmax greater than 4.4 (i.e. the mean SUVmax calculated in positive cases). Conclusion F-FCH PET/CT has a high diagnostic power in primary hyperparathyroidism and can be used for further evaluation of patients with inconclusive neck USG and Tc-MIBI SPECT/CT. SUVmax of the hyperfunctioning parathyroid gland seems to be predictive of disease severity in terms of serum PTH and bone mineral densitometry results. Studies with larger patient groups are needed to support these data.

Aims: Type 2 diabetes mellitus (T2DM) is a risk factor for severe COVID-19. Our aim was to compare the clinical outcomes of patients with and without T2DM during the first hit of COVID-19 in Istanbul.& nbsp; Methods: A retrospective population-based study was conducted including all consecutive adult symptomatic COVID-19 cases. Patients were confirmed with rt-PCR; treated and monitored in accordance with standard protocols. The primary endpoints were hospitalization and 30-day mortality.& nbsp; Results: Of the 93,571 patients, 22.6% had T2DM, with older age and higher BMI. Propensity Score matched evaluation resulted in significantly higher rates of hospitalization (1.5-fold), 30-day mortality (1.6-fold), and pneumonia (1.4-fold). They revealed more severe laboratory deviations, comorbidities, and frequent drug usage than the Non-DM group. In T2DM age, pneumonia, hypertension, obesity, and insulin-based therapies were associated with an increased likelihood of hospitalization; whereas age, male gender, lymphopenia, obesity, and insulin treatment were considerably associated with higher odds of death.& nbsp; Conclusions: COVID-19 patients with T2DM had worse clinical outcomes with higher hospitalization and 30-day mortality rates than those without diabetes. Compared to most territories of the world, COVID-19 mortality was much lower in Istanbul, which may be associated with accessible healthcare provision and the younger structure of the population.& nbsp; (C)& nbsp;2021 Elsevier B.V.

Hyperthyroidism is associated with increased metabolic activity and thermogenesis. Irisin is a key molecule in thermogenesis and energy expenditure via adipose tissue browning. Epicardial fat was previously defined as brown-like fat. Thus, here we aimed to evaluate the association between serum irisin level and epicardial fat thickness (EFT) in patients with hyperthyroidism.A total of 25 hyperthyroid patients and 24 age-, sex- and BMI-matched healthy controls were enrolled. Serum irisin levels, thyroid hormone levels, and body compositions were compared. EFT was measured via transthoracic echocardiography.Serum irisin level and EFT were significantly higher in the hyperthyroid group (p 0.001 and p = 0.001, respectively). The distributions of fat-free mass, muscle mass and fat mass were similar between the study groups. Serum irisin level was negatively correlated with TSH (p 0.001) and positively correlated with fT3 (p 0.001), fT4 (p 0.001) and TSH receptor antibody (p = 0.002) levels and EFT (p = 0.001). In multivariate linear regression analysis, TSH (β = -0.475, p 0.001) and EFT (β = 0.290, p = 0.023) levels were significantly associated with serum irisin levels.An increased serum irisin level associated with EFT might contribute to metabolic derangement in hyperthyroidism. Further studies are needed to elucidate whether irisin levels and EFT are affected by hyperthyroidism or vice versa.

INTRODUCTION Minimally invasive surgery is an alternative surgical approach for primary hyperparathyroidism with less surgical trauma and anaesthesia complications. When combined with intraoperative measurement of parathyroid hormone (PTH), cure rates are exceeding 97%. Preoperative intact PTH determination in washout samples is really very useful when parathyroid lesions cannot be easily distinguished from thyroid lesions or sometimes lymph nodes. Herein, we aimed to report our institutional experience about parathyroid fine-needle aspiration (FNA) method and suggest a cut-off ratio for this purpose. METHODS In our clinic, we performed ultrasonography (USG)-guided parathyroid FNA procedure for 131 patients diagnosed with primary hyperparathyroidism between January 2005 and January 2016. Both cytologic evaluation and intact PTH determination were performed in washout samples. Eighty-seven of the study group also had a parathyroid scintigraphy. Both demographic features and laboratory results were all recorded. RESULTS Median serum PTH level was 142 (113-197), while mean PTH washout level was 1824 (0-3953). When three of the localization techniques are compared with each other, FNA-PTH washout group had a better diagnostic accuracy (90.8%) when compared to cytology (7.92%) and MIBI (67.8%) groups. Both MIBI and FNA-PTH washout group had 100% positive predictive value (PPV) and 100% specificity. We found values greater than 436.5 pg/mL for FNA-PTH washout with a sensitivity of 90.3% and specificity of 88.9% (P

Treatment of aggressive pituitary tumors may be challenging. Temozolomide (TMZ) is a promising agent when conventional treatment methods fail. We present three patients with aggressive pituitary tumors with atypical morphology, who were resistant to conventional treatments and treated with TMZ. First case had a somatotroph adenoma, second a corticotroph adenoma, and the third a macroprolactinoma. We also reviewed the literature reporting TMZ efficacy in somatotroph, corticotroph and mammotroph tumors of pituitary. TMZ, 150-200 mg/m2 for 5 days in 28 days schedule was given to all patients. Among our patients, even though only the case of macroprolactinoma had a favorable response to TMZ treatment, both radiological and hormonal recurrences occurred 30 months after cessation of TMZ treatment. Then TMZ treatment was applied again. Cases of somatotroph and corticotroph adenomas had progressed under TMZ treatment and patients were lost due to mass effect of the tumor. Review of the literature demonstrated 67.3%, 60% and 26.7% overall response rates to the TMZ treatment in prolactinoma, corticotropinoma and somatostatinoma cases, respectively. There is still need to define response criteria uniformly to TMZ treatment in aggressive pituitary tumors and duration of response should be reported for reliable evaluation of results.

Aims Hypoglycemia constitutes a significant barrier to achieving glycemic control with insulin in both type 1 and type 2 diabetes. Historically, it has been difficult to accurately verify the rates of hypoglycemia within a clinical setting and there is a need for high-quality, real-world data to ascertain the true rates of hypoglycemia in clinical practice. The global Hypoglycemia Assessment Tool (HAT) study was designed to assess the global incidence of hypoglycemia in patients with insulin-treated diabetes, and the results have indicated that the overall incidence of hypoglycemia is high, with large variations between geographical regions. Methods The International Operations HAT (IO HAT) study retrospectively and prospectively assessed the incidence of hypoglycemia in patients with insulin-treated diabetes in Bangladesh, Colombia, Egypt, Indonesia, Philippines, Singapore, South Africa, Turkey, and United Arab Emirates. Results During the prospective period, hypoglycemic events were reported by 97.4% of patients with type 1 diabetes and 95.3% of those with type 2 diabetes, with an estimated rate of 6.86 events per patient per month (PPPM) for patients with type 1 diabetes and 2.37 events PPPM for patients with type 2 diabetes. Conclusions These results represent the first patient-reported dataset on hypoglycemia in the participating countries and confirm that hypoglycemia is under-reported and more widespread than previously believed. Although the incidence of hypoglycemia was variable among patients on different treatment regimens, there were substantial impacts on both productivity and healthcare utilization following an episode of hypoglycemia. This trial is registered at clinicaltrials.gov: NCT02306681.

Due to stimulated overall metabolism, a state of nutritional inadequacy often ensues, during thyrotoxicosis. We aimed to investigate circulating levels of some major components of the system that regulates energy stores, glucose, and fat metabolism, during thyrotoxicosis compared to euthyroidism. Fasting serum ghrelin, leptin, adiponectin, insulin, glucagon, glucose, as well as body fat composition were analyzed during thyrotoxicosis in 40 hyperthyroid patients (50.5 ± 15.2 years old, 22 females, 31 with Graves disease, and 9 with toxic nodular goiter). The same measurements were repeated an average 3 months later, when all patients achieved euthyroidism. Compared to euthyroidism, in thyrotoxicosis, patients had lower ghrelin and fat mass; had comparable insulin, HOMA-IR, glucagon, and leptin levels; higher levels of circulating adiponectin. Fasting serum glucose tended to be higher during thyrotoxicosis. The unique correlation of HOMA-IR was with the-glucagon to ghrelin ratio-(r = 0.801, p

SummaryObjective Symptomatic primary hyperparathyroidism (PHPT) is thought to be related to increased cardiovascular morbidity and mortality. In our study, we aimed to investigate endothelial dysfunction and markers of subclinical atherosclerosis in PHPT patients. Also we aimed to demonstrate the effect of vitamin D supplementation on these parameters. Materials and methods Twenty-nine patients followed by medical treatment (A), 25 preoperative (B) and 23 postoperative patients with PHPT (C), and 26 normocalcemic subjects (D) were included. Groups were assessed by measurements of flow-mediated dilation (FMD), carotid intima-media thickness (CIMT), serum levels of sCD40L, high-sensitivity CRP (hs-CRP), and interleukin-8 (IL-8). Thirteen patients with low levels of 25-hydroxy-vitamin D (25OHD) in the medical treatment group were assessed before and 3 months after vitamin D replacement. Results The median FMD was 5% in group A, 5.1% in group B, 7.6% in group C, and 7.7% in group D. The FMD measurement in group A was significantly lower than groups C and D (P = 0.02) and was similar to the FMD measurement in group B. FMD measurements of group B were not significantly lower than groups C and D. In 13 patients with low 25OHD in group A, the median FMD increased to 7.07% from 4.71% after vitamin D replacement (P = 0.02). Conclusion FMD was impaired in PHPT patients, particularly in the medically observed group. Vitamin D supplementation seems to provide improvements in FMD in medically observed PHPT patients with low 25OHD levels and this was the novel observation of our study.

There are controversial results and insufficient knowledge in the literature about the genetics of diabetes mellitus complications in the Turkish population and endothelial nitric oxide synthase (eNOS) gene polymorphisms may act as a potential modifier of diabetic vascular complications.The objective of this study was to determine the association between eNOS G894T polymorphisms and diabetes-related diseases.A Turkish case-control study was designed.The study was carried out in the Ankara University Hospital.Totally, 97 Turkish patients with diabetic foot ulcers and 102 controls were enrolled. Patients who had not received antimicrobial treatment in the preceding 6 months were included. Diabetic patients with hand and/or foot ulcers resulting from major trauma, such as road traffic accidents, were excluded.The effect of eNOS gene polymorphisms on diabetic complications and comorbid diseases was measured.Regarding eNOS G894T gene polymorphisms, 47.4% of the patients had GG (n = 46), 47.4% (n = 46) had GT, and 5.2% (n = 5) had TT alleles in the diabetes mellitus group, and 47.0% (n = 48), 41.2% (n = 42), and 11.8% (n = 12) had GG, GT, and TT alleles in the control group, respectively. There was no significant difference between the groups regarding the eNOS G894T gene allele ratios. Between groups with and without diabetic complications, a significant difference has only been found in the distribution of alleles in patients with comorbid atherosclerotic heart disease, whose GT-TT alleles were significantly higher than the GG alleles (p = 0.004).G894T polymorphism of eNOS gene was not associated with foot ulcer and diabetic complications, except in the presence of atherosclerotic heart disease.

There are many studies regarding the effect of iodine supplementation on goiter, but relatively few reports on the duration of iodine supplementation required to eradicate goiter in iodine-deficient regions. In the current study, we aimed to determine goiter prevalence as determined by sonographic methods, as it relates to changes in median urinary iodine concentrations (UIC) among school age children (SAC), ages 9-11.This study was performed in Ankara, Turkey, before and 5-10 years after mandatory iodination of table salt. Three hundred to 400 SAC from the same primary schools were studied every year by measurement of UIC as part of Turkish Iodine Surveys. Sonographically determined thyroid volume of the SAC had been measured before the mandatory iodination in 1997 and 5-10 years afterward, in 2002 and 2007. The prevalence of goiter in children was evaluated using World Health Organization/International Council for the Control of Iodine Deficiency Disorders recommendations for age and sex.Moderate iodine deficiency was present in 1997 (median UIC, 25.5 microg/L), and it improved to mild iodine deficiency in 2001 (median UIC, 87 microg/L). Sufficient iodine intake (median UIC, 117 microg/L) was achieved by the year 2004. Goiter prevalence was 25% in 1997, 12.3% in 2001, and decreased to 1.3% in 2004.The time required to normalize the prevalence of goiter in SAC living in a moderately iodine-deficient environment was at least a decade. To achieve a goiter rate of less than 5% among SAC, it may require that, as a population, they were born and grew up under conditions of iodine sufficiency.

Background: Cardiovascular disease is the most common cause of mortality around the world. The relationship between coronary artery disease and serum LDL-cholesterol levels has become obvious in recent years and statin treatment has been used more commonly. However, influence of intensive statin treatment on steroidal hormonal functions has remained unclear. In this paper, we evaluated the effect of very low LDL levels (

Amaç: Polikistik over hastalığı, doğurganlık çağındaki kadınlarda en sık görülen endokrin hastalığıdır. İnsulin direnci bu hastalık tablosunun ana patolojilerden birisidir. İnsulin duyarlılaştırıcı ajanlar ise bu sendromun tedavisinde klinik ve biyokimyasal açıdan başarı elde edilmesi amacıyla kullanılmasına karşın, bu ajanların PKOS’de kullanımını destekleyen direk veriler netlik kazanmamıştır. PKOS’da metformin ve roziglitazon tedavilerinin biyokimyasal ve klinik parametreler üzerine etkilerinin değerlendirmesi ve iki ilacın kıyaslanması. Metot: Çalışmaya PKOS tanısı almış 24 kadın dahil edildi. Tüm katılımcıların bazal antropometrik (VKİ, bel çevresi) ölçümleri kaydedildikten sonra adetin 2 ile 6. günleri arasında gece açlığını takiben açlık palzma glikozu, insulin, LH, FSH, DHEAS, total and serbest testosterone düzeyleri ölçüldü. İnsulin direnci göstergesi olarak HOMA-IR (Homeostasis model assessment score-insulin resistance) hesaplandı. Modifiye Ferriman Gallwey yöntemi ile hirsutizm skorlaması yapıldı. Sonrasında tüm kastılımcılar metformin (1700mg/gün) veya roziglitazon (4mg/gün) tedavilerine rastgele ayrıldılar. Yirmi dört haftalık tedavi süresi sonunda bazal değerlendirmesi yapılan tüm ölçütler tekrar değerlendirildi. Bazal ve son nokta ölçümleri tüm grupta ve tedavi gruplarında ayrı ayrı karşılaştırıldı. Bulgular: Bazal ölçümler içinde insulin ve serbest testosteron düzeyleri arasında istatistiksel olarak anlamlı bir ilişki saptandı. İnsulin duyarlılaştırıcı ilaçlar ile tedavi sonrasında tüm grup değerlendirildiğinde, serbest testosteron düzeyleri, hirsutizm skorları ve mastrüel siklus sıklığında istatistiksel olarak anlamlı biçimde düzelme gözlenirken (sırasıyla, P=.004, P=.049 ve P=.001), açlık insulin düzeylerinde ve HOMA-IR ölçümlerinde düzelme ise istatistiksel olarak anlamlı değildi. Tedavi grupları ayrı ayrı analiz edildiğinde, metformin grubu hirsutizm skorlarında istatistiksel olarak anlamlı olmayan bir düzelme gözlenirken diğer ölçütlerde benzer sonuçlar elde edildi. Sonuç: Bu bulgular, metformin ve roziglitazon tedavilerinin PKOS’nin klinik ve biyokimyasal bulgularında iyileşme sağladığını göstermektedir. Bu iki ilaç etkinliği açısından biri diğerine üstün olmadığı söylenebilir. Ancak daha çok denek içeren çalışmalara ihtiyaç vardır.

Osteoporosis and cardiovascular disease are major health problems that lead to morbidity and mortality. Bisphosphonates are among the drugs used most frequently worldwide to treat osteoporosis, especially in older women. B-mode ultrasonography has recently become a valuable tool for early diagnosis of atherosclerotic disease because of its ability to measure carotid artery intima media thickness (CIMT). The purpose of the present study was to investigate whether alendronate sodium therapy has an effect on CIMT in postmenopausal women with osteoporosis. A total of 71 postmenopausal women with osteoporosis were evaluated before and after they began taking alendronate sodium; follow-up was provided for an average of 13+/-2 mo. Osteoporosis was diagnosed with the use of dual-energy x-ray absorptiometry, and therapy with alendronate sodium was begun at a dose of 70 mg/wk. For CIMT, B-mode ultrasonography was performed on the right and left middle and distal main carotid arteries. Before alendronate sodium therapy was initiated, the average CIMT value was 0.734+/-0.121 mm; after therapy, the average CIMT was 0.712+/-0.111 mm. This difference was not confirmed to be statistically significant. Treatment of osteoporosis does not seem to have an effect on CIMT, which is an early marker of atherosclerosis.

WOS: 000362601700003 Purpose: This open-label, single-arm, phase 4 study was designed to evaluate the efficacy of intensive insulin glargine titration in type 2 diabetes mellitus (T2DM) patients for 6 months to reach good glycaemic control. Material and Method: Two hundred-forty one insulin-naive T2DM patients were included. The primary efficacy variable was the glycaemic control (HbA1c level of

Ovary is the main source of the hyperandrogenism in polycystic ovary syndrome (PCOS). Adrenal glands may also be involved in the pathogenesis of the development of PCOS. To investigate this possibility and to find out if buserelin test is able to distinguish PCOS patients from the patients with idiopathic hirsutism (IH), ACTH and buserelin tests were performed in 29 women with PCOS, 21 women with IH, and 20 control subjects (CS). We also aimed to determine the role of dysregulation of 17 hydroxylase in the development of PCOS. Basal and stimulated dehydroepiandrosterone sulfate (DHEA-S) and stimulated cortisol (F) levels after ACTH administration were significantly higher in PCOS group than in IH and CS groups (p
