Abstract
BACKGROUND Stathmin is a phosphoprotein that plays a role in intercellular and intracellular signalization, inflammation, and differentiation. Our aim was to evaluate the stathmin-2 level and its relationship with the metabolic parameters of newly diagnosed type 2 diabetes mellitus (nT2DM) patients. MATERIAL AND METHOD This case-control study included 76 patients with nT2DM and 76 healthy individuals with a normal oral glucose tolerance test who were matched for body mass index (BMI), age, and gender. In addition to laboratory and anthropometric measurements related to type 2 diabetes mellitus (T2DM), stathmin-2 levels were determined using an enzyme-linked immunosorbent assay. RESULTS We observed significantly higher circulating stathmin-2 levels in subjects with T2DM compared to the control group (6.39±1.60 ng/mL and 4.66±0.80 ng/mL, p<0.0001). In patients with metabolic syndrome, circulating stathmin-2 levels were significantly elevated compared to those without metabolic syndrome in both the T2DM and control groups (T2DM: 7.16±1.24 vs 5.06±1.24 ng/mL, p<0.001; Control: 3.84±1.40 vs 3.82±1.40 ng/mL). In both groups, we observed a positive correlation between stathmin-2 levels and BMI and circumference. Moreover, stathmin-2 showed a positive correlation with high-sensitivity C-reactive protein (hs-CRP), homeostatic model assessment of insulin resistance, insulin, fasting blood glucose, hemoglobin A1c, BMI, low-density lipoprotein cholesterol, and total cholesterol. A negative correlation was observed with stathmin-2 and high-density lipoprotein cholesterol. Stathmin-2 did not show any correlation with age, triglyceride, and lactate dehydrogenase. CONCLUSIONS Stathmin-2 levels were found to be elevated in patients with nT2DM and exhibited positive correlations with hyperinsulinaemia, hyperglycaemia, HOMO-IR and hs-CRP levels. These results indicate that stathmin-2 may play a role in T2DM pathogenesis.

Abstract
PURPOSE The OPG/RANKL (osteoprotegerin/receptor activator of nuclear factor kappa-B) system, which plays a crucial role in bone metabolism, is also associated with vascular calcification. Acromegaly is characterized by excessive secretion of growth hormone and insulin-like growth factor, and studies have demonstrated an elevated risk of cardiovascular disease in individuals with acromegaly. In this study, our objective was to investigate the relationship between OPG/RANKL and various cardiovascular risk scoring systems. METHODS We recruited 44 consecutive acromegaly patients and 41 healthy controls with a similar age and gender distribution for this study. RESULTS While RANKL levels were significantly higher in the acromegaly group compared to the controls, OPG levels were not found to be significantly different between the two groups. Furthermore, within the acromegaly group, RANKL levels were significantly higher in patients with active acromegaly compared to those with controlled acromegaly. Osteoprotegerin levels showed a positive correlation with the Framingham risk score (FRS) in the acromegaly group. Linear regression analysis revealed an association of OPG with FRS (adjusted R2 value of 21.7%). CONCLUSION OPG and RANKL may serve as potential markers for assessment of cardiovascular calcification and prediction of the cardiovascular risk status in acromegalic patients.

Abstract
BACKGROUND Epiregulin is a molecule that plays a role in cell proliferation, tumor development, inflammation, and angiogenesis in malignant diseases. AIM Our study aims to reveal, for the first time, the predictive value of this molecule in non-Hodgkin lymphoma (NHL) and its association with disease stage, cell type, and extranodal involvement. METHODS The study is an observational case-control trial involving 60 newly diagnosed NHL patients and 60 healthy individuals (control group) between 18 and 75 years old. Demographic characteristics of all volunteers, stages of patients' illnesses and lymphoma cell types, hemogram, biochemistry tests, beta 2-microglobulin, C-reactive protein (CRP), and epiregulin levels were measured and statistically evaluated. RESULTS Epiregulin levels were significantly higher in NHL patients compared to the control group (P < 0.0001). Similarly, a significant increase in epiregulin levels was observed in advanced NHL patients. Furthermore, the most common NHL subgroup within the NHL group, diffuse Large B Cell Lymphoma (DLBCL), and the subgroup with extranodal involvement also had significantly higher levels of epiregulin. A positive correlation was found between the epiregulin molecule and CRP, beta 2-microglobulin, and lactate dehydrogenase (LDH) levels in NHL patients. CONCLUSION Our study suggests that serum epiregulin levels, discovered to increase in NHL patients for the first time, may be an independent predictive molecule in an advanced stage, extranodal involvement, and the DLBCL subtype of this disease. Epiregulin positively correlates with prognostic molecules such as beta 2-microglobulin, LDH, and CRP. Illuminating its potential role in NHL pathogenesis could make epiregulin a vital drug target for treatment.

Abstract
OBJECTIVES We investigated the relationship between serum kallistatin and kidney disease and proteinuria in nondiabetic obesity-related chronic kidney disease and observed the effects on arterial stiffness. MATERIALS AND METHODS We included 40 patients with nondiabetic obesity-related chronic kidney disease followed in our nephrology clinic and a control group of 40 participants without chronic kidney disease matched by age, sex, and mean body mass index (measured as weight in kilograms divided by height in meters squared). Pulse-wave velocity and augmentation index were measured oscillometrically by pulse-wave analysis (Mobil-O-Graph) by the same operator. Serum kallistatin levels were measured by sandwich enzyme-linked immunosorbent assay. RESULTS Mean age of patients was 51 ± 7.5 years (range, 29-62 years), and 40% were female. Mean body mass index was 35 ± 3.1. Four patients (10%) had morbid obesity; 21 (52.5%) had hypertension. Glomerular filtration rate (42 ± 18 vs 83 ± 15 mL/min/1.73 m², respectively; P < .001) were significantly lower. However proteinuria (671 ± 1031 vs 80 ± 30 mg/d, respectively; P < .001) were significantly higher in patients than in controls. Also, serum kallistatin and arterial stiffness were significantly higher in patients (P < .05).''The Pulse Wave Velocity was higher in patients with hypertension (P = .01); GFR was lower (P < .01); serum uric acid level was higher (P < .001); and neutrophil-to-lymphocyte ratio (P < .05), C-reactive protein level (P < .05), and serum kallistatin level were higher (P < .05). CONCLUSIONS Serum kallistatin levels increase in patients with obesity-related kidney disease. Especially hypertension and hyperuricemia are associated with an increase in serum kallistatin.

Abstract
BACKGROUND Neudesin is a protein that is secreted from adipose tissue and central nervous system and has a regulatory function on energy metabolism. Although the effect of this protein is shown in the experimental model of type-2 diabetes mellitus (type-2DM), its effect in humans is not clearly known. In this study, we aimed to evaluate the relationship between serum neudesin level and metabolic, anthropometric and cardiovascular parameters in newly diagnosed type-2DM patients (group 1). METHODS Forty patients in each were included in our study for group 1 and for the control group (group 2), which consisted of age and sex-matched healthy subjects. Serum neudesin, hs-CRP, carotid intima media thickness (CIMT), Body Mass Index (BMI) and insulin resistance (HOMA-IR) levels were compared prospectively. RESULTS Serum neudesin levels were significantly higher in diabetic patients than in the control group (type-2DM: 64.69±3.06 ng/mL, control: 55.52±5.48 ng/mL, P=0.004*). There was an independent relationship between serum neudesin and HOMA-IR and BMI. Although there is a correlation between serum neudesin and CIMT; this feature disappeared in the regression analysis. CONCLUSIONS Serum neudesin increased in new diagnosis type-2DM patients. This increase seems to be related to obesity and insulin resistance. However, more extensive research is needed to clarify this issue.

Abstract
Introduction In circulation, 99% vitamin D is transported by binding to vitamin D binding protein (VDBP) and albumin. Vitamin D at free form and vitamin D binding to albumin are defined as bioavailable vitamin D. Vitamin D deficiency is associated with atherogenic lipid profile and insulin resistance. Remnant cholesterol is defined as the cholesterol component of triglyceride-rich lipoproteins and contributes to the atherosclerotic burden. The aim of this study was to investigate the association between bioavailable vitamin D and remnant cholesterol in patients with type 2 diabetes mellitus (T2DM). Methods A total of 198 T2DM patients and 208 non-diabetic subjects underwent biochemical measurements of lipid profiles, 25(OH)D, VDBP, CRP and albumin levels. Their demographic characteristics (age, sex) were questioned. Subjects with thyroid, kidney and liver dysfunction and using lipid-lowering therapy were not included in the study. The diagnosis of T2DM was made according to the American Diabetes Association ADA 2016 criteria. Classification of vitamin D levels was done according to the Endocrine Society. Bioavailable vitamin D concentrations were calculated. Results High-density lipoprotein cholesterol (HDL), 25(OH)D, free vitamin D and bioavailable vitamin D levels were significantly lower in diabetic patients than in non-diabetic patients while triglyceride, remnant cholesterol and CRP levels were found to be significantly higher. VDBP was positively correlated with CRP and remnant cholesterol in diabetic patients, but not in non-diabetic patients. Cut-off values were determined from non-diabetics as 3.56 ng/mL for bioavailable vitamin D and 26.56 mg/dL for remnant cholesterol. Logistic regression analysis in the control group showed that the odds ratio for increasing remnant cholesterol above the cut-off value was determined as 2.01 for low bioavailable vitamin D and 1.1 for elevated CRP. However, in T2DM there was no significant relationship. In all subjects, low bioavailable vitamin D increased the remnant cholesterol above the cut-off by 2.18-fold independent of the presence of T2DM. However, there was no significant risk to increase remnant cholesterol, considering a total 25(OH) D deficiency in all groups. Conclusions Low bioavailable vitamin D was found to be a risk factor for elevated remnant cholesterol. This relationship was not detected in patients with T2DM. We believe that the inflammation observed in Diabetes Mellitus may increase the concentrations of VDBP and a decrease in bioavailable vitamin D levels. Therefore, measuring VDBP and calculating the bioavailable vitamin D may provide additional information about the actual vitamin D status.

Abstract
PURPOSE Recent studies have shown that cytokines secreted from adipose tissues play a role in the pathogenesis of type 2 diabetes mellitus (T2DM). CTRP5 (C1q-TNF-related protein 5) is a novel adipokine that has been shown to be associated with glucose and lipid metabolism. Varying levels of CTRP5 have been reported in individuals with diabetes, obesity and coronary artery disease. The aim of this study was to examine serum levels of CTRP5 and to show the relationship with cardiometabolic parameters in T2DM patients. METHOD The study included 40 T2DM patients and 40 age- and sex-matched healthy control subjects. All the study participants were evaluated with respect to BMI, waist circumference, lipid profile, insulin resistance (HOMA-IR), serum CTRP5 levels, carotid intima-media thickness, and hs-CRP. RESULTS No statistically significant differences were found between the control group and the diabetic group in terms of age, sex, or BMI. Serum CTRP5 levels (T2DM = 94.55 ± 28.70 ng/ml, control = 76.02 ± 27.22 ng/ml, P = 0.004*) were significantly higher in the group of newly diagnosed diabetic patients. A positive correlation was found between CTRP5 and the cardiometabolic parameters of carotid intima-media thickness (CIMT), hs-CRP, HOMA-IR and BMI. Regression analysis results showed that CTRP5 levels were independently correlated with insulin resistance estimated by HOMA-IR. CONCLUSION Serum CTRP5 levels were correlated with cardiometabolic parameters and could therefore be a promising indicator of metabolic status and a possible biomarker of insulin resistance. However, the contradictory results reported in different studies indicate the need for further research to assess the significance of CTRP5 for diagnosis and monitoring of treatment efficacy.

Abstract
Background The results of cardiac troponin I (cTnI) methods used in the diagnosis of acute myocardial infarction (AMI) are highly variable. In this study, it was aimed to compare the analytical performance of the Mindray CL-series TnI method with the Beckman Coulter-Access II AccuTnI+3 method. Methods Analytical performance and method comparison experiments for cTnI measurement with Mindray CL-1000i and Beckman Coulter-Access II instruments were with the Clinical and Laboratory Standards Institute (CLSI) documents EP15-A3 and EP9-A3. Precision studies were performed with commercially available third-party quality control (QC) materials. Method comparison experiments were performed by using patient samples. Furthermore, the limit of quantification (LoQ), total analytical error (TAE), and sigma metrics of both methods was determined. Results The repeatability CV% for the three levels of Mindray CL-series TnI were 1.86, 1.75, and 1.08, while within the laboratory, CV% values were 3.36, 5.27, and 5.82. The quantification limits for Mindray CL-series and Beckman AccuTnI+3 were found to be 0.0085 and 0.0366 ng/mL with a CV level of less than 10%, respectively. The Mindray CL-series TnI results in the method comparison study were higher compared to the Beckman Coulter Access II AccuTnI+3 method. Conclusions With low repeatability, low bias, and low LoQ, The Mindray CL-series cTnI method shows it may be used safely in its category. The significant difference between the two methods in the method comparison study reveals cTnI methods in the market should be standardized to ensure global traceability.

Abstract
Neudesin is a neuropeptide hormone involves in female reproduction system via promoting effects of progesterone. Polycystic ovary syndrome (PCOS) is a metabolic and reproductive disorder associated with hypothalamic-pituitary-ovarian axis abnormalities and impaired negative feedback mechanism of progesterone upon gonadotropin-releasing hormone secretion. Our aims were to discover whether neudesin levels were altered in PCOS women comparing to controls and to determine the link of neudesin with hormonal-metabolic parameters in PCOS women. The current research was designed as a case-control study. Sixty-eight subjects with PCOS and 67 age- and body mass index (BMI)-matched subjects as controls were enrolled into the study. Circulating neudesin levels were measured by ELISA. Neudesin levels were significantly lower in PCOS subjects compared to controls (4.07 ± 1.22 vs. 6.02 ± 2.07 ng/ml, p < .001). Neudesin exhibited an inversely independent link with luteinizing hormone, free-androgen index, and BMI whereas it showed a positively independent link with progesterone in women with PCOS. Logistic regression analysis revealed that decreased neudesin levels were parallel with increased risk of having PCOS. Decreased neudesin levels were associated with hormonal disturbances in PCOS women, suggesting that neudesin may play a role in pathophysiology of PCOS.

Abstract
BACKGROUND Urocortin 3 (UCN3) is a peptide hormone playing a pivotal role in glucose and lipid metabolisms. However, its clinical implications remain unclear. Our aims were to investigate the altered levels of UCN3 in newly diagnosed type 2 diabetes mellitus (nT2DM) patients in comparison to subjects with normal glucose tolerance (NGT) and to determine the presence of any possible link between UCN3 levels and metabolic parameters. METHODS Eighty nT2DM and 80 age-, body mass index (BMI)-, and gender-matched NGT subjects were enrolled into this case-control study. The circulating UCN3 levels were measured using the enzyme-linked immunoabsorbent assay (ELISA). Metabolic parameters of enrolled subjects were also determined. A standard 75-g 2-hour oral glucose tolerance test was used for diagnosis of type 2 diabetes mellitus (T2DM). RESULTS UCN3 levels were higher in subjects with nT2DM than in controls (115.64 ± 39.26 vs 86.16 ± 22.81 pg/mL, P < .001). UCN3 levels were increased in subjects with metabolic syndrome compared to subjects without metabolic syndrome in both nT2DM and NGT groups. UCN3 levels showed a positive correlation with BMI in both groups. Moreover, UCN3 levels were positively and independently associated with insulin, fasting blood glucose, insulin resistance, 2-hour plasma glucose, glycosylated hemoglobin, and triglycerides, whereas UCN3 levels were negatively and independently associated with high-density lipoprotein cholesterol. According to logistic regression analysis, increased risk of T2DM and metabolic syndrome were parallel with the highest elevated levels of UCN3. CONCLUSIONS Increased levels of UCN3 are associated with unfavorable metabolic profiles in T2DM, indicating a potential role of UCN3 in glucose and lipid metabolisms in T2DM.

Abstract
BACKGROUND Sortilin, a pluripotent peptide hormone, plays a role in glucose and lipid metabolism. A link between sortilin and insulin sensitivity has been implicated. However, the clinical implications of this link remain elusive. Our aims were to investigate whether sortilin levels were altered in subjects with newly diagnosed type 2 diabetes mellitus (nT2DM) compared with subjects with normal glucose tolerance (NGT) and to determine whether a link exist between sortilin levels and metabolic parameters. MATERIALS AND METHODS A total of 150 subjects including 75 nT2DM patients and 75 subjects with NGT who were matched in age, body mass index, and sex were enrolled into this case-control study. The circulating levels of sortilin were measured using enzyme-linked immunosorbent assay. A 2-hour 75-g oral glucose tolerance test was used for diagnosis of T2DM. Metabolic parameters of enrolled subjects were also determined. RESULTS The circulating levels of sortilin were found to be significantly lower in subjects with nT2DM than in controls (138.44 ± 38.39 vs. 184.93 ± 49.67 pg/mL, P < 0.001). Sortilin levels showed a negative correlation with insulin resistance and unfavorable lipid profiles, while they were positively correlated with high-density lipoprotein cholesterol in subjects with nT2DM. Linear regression analysis showed an independent and inverse link between sortilin and insulin resistance and unfavorable lipid profiles. Moreover, logistic regression analysis revealed that the subjects with the lowest sortilin levels had an increased risk of nT2DM compared with those subjects with the highest sortilin levels. CONCLUSIONS Decreased circulating levels of sortilin were associated with unfavorable metabolic profiles in subjects with nT2DM.

Abstract
PURPOSE Insulin-like peptide 5 (INSL5) is a gut peptide hormone that is a member of relaxin/insulin superfamily. Growing evidence implicates the crucial role of the peptide in some metabolisms including food intake, glucose homeostasis and reproductive system. Polycystic ovary syndrome (PCOS) is involved in both reproductive and metabolic issues. The aim of the study was determination of circulating levels of INSL5 alteration in women with PCOS and evaluation of the relationship between INSL5 and hormonal-metabolic parameters as well as carotid intima media thickness (cIMT). METHODS A total of 164 subjects were recruited in this cross-sectional study (82 women with PCOS and 82 age- and BMI-matched controls). Circulating INSL5 levels were assessed via ELISA method. High-resolution B-mode ultrasound was used to measure cIMT. The hormonal and metabolic parameters of the recruited subjects were determined. RESULTS Circulating INSL5 levels were significantly elevated in women with PCOS compared to controls (27.63 ± 7.74 vs. 19.90 ± 5.85 ng/ml, P < 0.001). The mean values of INSL5 were significantly higher in overweight subjects compared to lean weight subjects in both groups. The women with PCOS having insulin resistance have increased INSL5 compared to those of PCOS subjects without insulin resistance. INSL5 is associated with insulin resistance, BMI, luteinizing hormone and free androgen index. Multivariate logistic regression analyses revealed that the odds ratio for having PCOS in the highest tertile of INSL5 was higher than in the lowest tertile. CONCLUSIONS PCOS subjects exhibited an elevation in circulating INSL5 levels along with a link between INSL5 level induction and metabolic-hormonal parameters.

Abstract
PURPOSE Fibroblast growth factor-21 (FGF-21) is a member of fibroblast growth factor family. Both growth hormone (GH) and FGF-21 take place in the regulation of glucose and lipid metabolism. We aimed to investigate FGF-21 levels in acromegaly which is characterized by excess GH levels and is associated with comorbidities and altered body composition. METHODS We studied 43 subjects (21 females and 22 males, mean age of 50.0 ± 12.8) with acromegaly. The control group consisted of 40 gender- and age-matched subjects (25 females and 15 males, mean age of 48.8 ± 8.8). Acromegaly patients were classified into two groups; active acromegaly (AA; n = 26) and controlled acromegaly (CA; n = 17). Metabolic, anthropometric and laboratory values of subjects were recorded. FGF-21 level was measured by ELISA assay. RESULTS Median FGF-21 levels were significantly higher in acromegaly group compared to control group (85.5 vs. 59.0 pg/mL, p = 0.02, respectively). In the multiple regression model, FPG, A1c, HOMA-IR, glucose intolerance, BMI, visceral fat, hs-CRP, presence of hypertension, dyslipidemia and acromegaly were included as independent variables to explain variability of plasma FGF-21 levels in whole study group. The presence of acromegaly was the only determinant of increased FGF-21 levels in the whole study group (β coefficient = 0.253, p = 0.006). CONCLUSION FGF-21 levels were increased significantly in acromegaly group. Increased FGF-21 levels were significantly and independently associated with the state of acromegaly. Acromegaly may also be a FGF-21 resistance state independent from insulin resistance, glucose intolerance, obesity, hypertension and dyslipidemia.

Abstract
BACKGROUND The objective of this study was to evaluate the effect of weight loss with hypocaloric diet and orlistat treatment in addition to hypocaloric diet on gut-derived hormones ghrelin and obestatin. MATERIALS AND METHODS A total of 52, euglycemic and euthyroid, obese female patients were involved in the study. The patients were assigned to two groups: Group 1 (n = 26) received hypocaloric diet alone and Group 2 (n = 26) received orlistat in addition to hypocaloric diet for 12 weeks. Anthropometric measurements, serum lipid, insulin levels, and obestatin and ghrelin values were assessed at the beginning of the study and after 12 weeks of therapy. RESULTS Baseline clinical characteristics and laboratory parameters including serum ghrelin and obestatin concentrations and ghrelin/obestatin ratio were similar between the two groups. After 12 weeks, mean change in BMI, fat mass, and fat-free mass (FFM) were -1.97 ± 1.56 kg/m2 (P = 0.003), -2.63% ±2.11% (P = 0.003), and -1.06 ± 0.82 kg (P = 0.003), respectively, in Group 1. In Group 2, mean change in BMI was -2.11 ± 1.24 kg/m2 (P = 0.001), fat mass was -3.09% ±2.28% (P = 0.002), and FFM was -1.26 ± 0.54 kg (P = 0.001). However, fasting glucose, lipid, and insulin levels did not change in Group 1. Furthermore, except serum high-density lipoprotein cholesterol and triglyceride levels, no significant change was observed in Group 2. Although serum ghrelin and obestatin concentrations increased significantly in both groups (Group 1: pGhrelin: 0.047, pobestatin: 0.001 and Group 2: pGhrelin: 0.028, pobestatin: 0.006), ghrelin/obestatin ratio did not change significantly. When the changes in anthropometric assessments and laboratory parameters were compared, no significant difference was observed between the two groups. Furthermore, no correlation was observed between ghrelin or obestatin and any other hormonal and metabolic parameters. CONCLUSION Weight loss with diet and diet plus orlistat is both associated with increased ghrelin and obestatin concentrations.

Abstract
Objective C1q/tumor necrosis factor-related protein-5 (CTRP5) is a novel peptide hormone involved in the metabolism of energy regulation. Polycystic ovary syndrome (PCOS), which is a reproductive and metabolic disorder, is associated with insulin resistance. The aim of the current study was to compare circulating levels of CTRP5 in women with and without PCOS and to investigate possible associations between CTRP5 and metabolic-hormonal parameters. Material and Methods The present cross-sectional study contained 80 women with PCOS and 80 age and body mass index-matched women without PCOS. Circulating levels of CTRP5 were calculated using an enzyme-linked immunosorbent assay. We also measured hormonal and metabolic parameters. Results Patients with PCOS had lower levels of circulating CTRP5 compared with women without PCOS (6.90±2.64 vs 11.73±3.66 ng/mL, p<0.001). CTRP5 was negatively correlated with insulin resistance, free-androgen index, and body mass index in both the PCOS and control groups. Moreover, patients with PCOS who had insulin resistance showed lower circulating CTRP5 levels compared with those without insulin resistance. In both the control and PCOS groups, overweight subjects had lower circulating levels of CTRP5 compared with participants of normal weight. Logistic regression analyses indicated that subjects in the lowest tertile for CTRP5 level had higher risk for PCOS compared with those in the highest tertile of CTRP5. Conclusion Decreased circulating levels of CTRP5 were associated with higher risk of PCOS, as well as having metabolic disturbance among women with PCOS.

Abstract
BACKGROUND This study investigated the effect of matrix metalloproteinase (MMP)-9 and 10, and stress hyperglycaemia on the necessity of emergency renal replacement therapy (RRT) and mortality in nondiabetic geriatric patients with acute kidney injury (AKI). MATERIALS AND METHODS The present observational and longitudinal study included 101 nondiabetic geriatric patients (age >65 years) with AKI. The serum levels of MMP-9 and MMP-10 were evaluated in these patients. Serum glucose level >140 mg/dL at the time of admission was accepted as stress hyperglycaemia. RESULTS The average age of patients was 81 ± 7.1 years. Stress hyperglycaemia was diagnosed in 34.6% of the cases; the majority of these cases were patients with high-serum urea, CRP, and chronic kidney disease. The average levels of MMP-9 and MMP-10 were found to be 199 ± 38 and 16.5 ± 7.5 ng/mL, respectively. Thirty-one cases (30.6%) mortality during hospitalization and 20 cases (20%) underwent emergency RRT. Multiregression analysis showed the serum urea (P < .001) and stress hyperglycaemia (P = .03) to be independently associated with mortality. Also, serum urea (P = .01), potassium level (P = .03), and MMP-10 levels (P = .03) were independently associated with the necessity of the emergency RRT. The MMP-9 levels exhibited no relation with the necessity of emergency RRT and mortality. CONCLUSION Stress hyperglycaemia is a common condition among nondiabetic geriatric patients with AKI and is related to mortality. Serum MMP-10 levels serve as an important predictor of the necessity of emergency RRT in these patients.

Abstract
OBJECTIVE Bone morphogenic protein-4 (BMP-4) is a proinflammatory cytokine which is controlled by BMP-4 antagonists. Our aim was to investigate the levels of BMP-4 and its antagonists, noggin and matrix Gla protein (MGP), in prediabetes and diabetes. DESIGN One hundred and forty-two type 2 diabetic, 32 prediabetic, and 58 control subjects participated in this cross-sectional study. BMP-4, noggin, and MGP were measured with the ELISA method. RESULTS There was a significant difference between the three groups in relation to sex, hypertension, fasting plasma glucose, HbA1c, lipid profiles, and diastolic blood pressure (p < 0.05). BMP-4 levels were significantly lower in the diabetic group compared to the control group (108.5 and 127.5 ng/mL, respectively, p < 0.001 diabetes vs. control). Noggin levels were significantly lower in the diabetic group compared to the prediabetic and control groups (10.5, 11.5, and 12.0 ng/mL, as median, respectively, p < 0.001; diabetes vs. control, p = 0.002; diabetes vs. prediabetes). BMP-4 was associated significantly with noggin in the entire study population (ß coefficient = 0.796, p < 0.001). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve was 0.708 (95% CI 0.551-0.864, p = 0.011) for BMP-4 levels. The optimal cutoff value of BMP-4 for detecting albuminuria was 118.5 ng/mL for which sensitivity was 71.4% and specificity was 66.4%. CONCLUSIONS BMP-4 and noggin levels were lower in the diabetic group. High BMP-4 levels were significantly associated with albuminuria. Further studies are warranted to determine the role of BMP-4 in the pathogenic processes underlying albuminuria and hyperglycemia in patients with type 2 diabetes.

Abstract
BACKGROUND Ectopic pregnancies constitute about 2% of all pregnancies which are the leading cause of pregnancy-related deaths and a considerable cause of maternal morbidity. Oxidative stress can lead to a number of pregnancy related diseases including miscarriage, eclampsia and preterm labor. Ischemia modified albumin (IMA) which reflects the oxidative stress may be used as a marker for ectopic pregnancy. Our aim was to compare the levels of IMA and total antioxidant status (TAS) in ectopic and normal pregnancies and to understand if IMA can be used as a marker to diagnose ectopic pregnancy. MATERIALS AND METHODS Our case-control study consisted of 38 women with ectopic and 42 women with normal pregnancy. IMA and TAS levels were determined in serum samples with an albumin-cobalt binding test and by commercially available kits, respectively. IMA levels were adjusted according to serum albumin levels. Index of oxidation (IOS) was calculated by dividing adjusted IMA (A-IMA) levels with TAS. A receiver operating characteristics (ROC) curve analysis was made and cut-off values for the biomarkers were investigated in SPSS 21.0 program (SPSS, Chicago, IL). Data were presented as mean ± standard deviation and a p value < .05 was accepted as statistically significant. RESULTS There was a statistically significant difference in IMA, A-IMA, and IOS levels between ectopic and normal pregnancies. Although TAS level was not different statistically, it was lower in ectopic pregnancy. According to ROC curve analysis, IOS had the largest area under curve. A cut-off value of 0.545 for IOS had 81.6% sensitivity and 59.5% specificity. CONCLUSIONS According to our study, oxidative stress plays an important role in ectopic pregnancy and either A-IMA or IOS can be evaluated as a marker of ectopic pregnancy after further studies.

Abstract
BACKGROUND Growing evidence suggest that macrophage migration inhibitory factor (MIF) plays a vital role in glucose metabolism. We aimed to ascertain whether MIF levels are altered in subjects with prediabetes and also to determine the relationship between MIF and metabolic parameters as well as visceral fat mass. MATERIAL AND METHODS This cross-sectional study included 40 subjects with prediabetes and 40 age-, body mass index (BMI)- and sex-matched subjects with normal glucose tolerance. Circulating MIF levels were measured using enzyme-linked immunosorbent assay. Metabolic parameters of recruited subjects were evaluated. Visceral fat mass was measured using bioelectrical impedance method. RESULTS Circulating MIF levels were found to be elevated in subjects with prediabetes compared to controls (26.46 ± 16.98 versus 17.44 ± 11.80 ng/mL, P = 0.007). MIF positively correlated with BMI, visceral fat mass and indirect indices of homeostasis model assessment of insulin resistance. In linear regression model, an independent association was found between MIF levels and metabolic parameters, including BMI, visceral fat mass and homeostasis model assessment of insulin resistance. Multivariate logistic regression analyses revealed that the odds ratio for prediabetes was higher in subjects in the highest quartile of MIF compared to those in the lowest quartile, after adjusting for potential confounders. CONCLUSIONS Increased MIF levels are associated with the elevation of prediabetic risk.

Abstract
OBJECTIVES We evaluated long-term results and infections requiring hospitalization in kidney transplant patients with Familial Mediterranean Fever (associated amyloidosis-type). MATERIALS AND METHODS We retrospectively reviewed medical records of patients with familial Mediterranean fever with at least 1-year posttransplant follow-up. Kidney transplant recipients with primary glomerulonephritis and equivalent demography, immunity status, and follow-up comprised the control group. RESULTS In 32 patients with familial Mediterranean fever versus 25 control patients (mean follow-up 82 ± 57 vs 79 ± 54 mo; P = .82), average serum creatinine values were 1.7 ± 0.9 versus 1.5 ± 1.0 mg/dL (P = .41) at discharge, 1.4 ± 0.4 versus 1.3 ± 0.5 mg/dL (P = .44) at 1 year, 1.4 ± 0.6 versus 1.3 ± 0.5 mg/dL (P = .63) at 3 years, and 2.0 ± 1.5 versus 2.1 ± 1.5 mg/dL (P = .92) at last follow-up. Groups were not statistically different regarding average inpatient and number of hospitalizations due to infections at 1 year; however, at last follow-up, 26 patients with familial Mediterranean fever (81%) had 8.6 average admissions and 13 control patients (52%) had 2.8 average admissions (P = .02, P < .01). Early posttransplant, both groups were taking a triple drug immunosuppression regimen. However, at 1 and 3 years posttransplant, withdrawal and/or minimization occurred in 40.6% and 83.3% of patients with familial Mediterranean fever and 28% and 55.5% of control patients (P < .05, P < .05). During follow-up, 6 familial Mediterranean fever patients (18.7%) and 2 control patients (8%) died (P = .23). CONCLUSIONS Although renal transplant patients with associated amyloidosis-type familial Mediterranean fever and those with glomerulonephritis have similar rejection and/or graft loss rates, hospital admissions due to infection and increased mortality are more common in the familial Mediterranean fever group, with immunosuppression drug withdrawal.

Abstract
PURPOSE Endocan is a proteoglycan secreted mainly from endothelial cells. It has been implicated that there is a link between endocan and endothelial dysfunction. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with increased risk of cardiovascular events. The aims of this study were to ascertain whether circulating endocan levels are altered in women with PCOS, and whether there is an association between endocan and carotid intima media thickness (cIMT). MATERIALS AND METHODS This cross-sectional study included 80 women with PCOS and 80 age- and BMI-matched controls without PCOS. Circulating endocan levels were measured using ELISA. Metabolic, hormonal parameters and cIMT were determined. 2-h oral glucose tolerance test (2-h OGTT) was performed on all women. RESULTS Circulating endocan levels were significantly elevated in women with PCOS compared with controls (5.99 ± 2.37 vs. 3.66 ± 1.79 ng/ml, P < 0.001). Endocan levels positively correlated with BMI, homeostasis model assessment of insulin resistance (HOMA-IR), free androgen index (FAI), high-sensitivity C-reactive protein (hs-CRP), and cIMT in both PCOS and control groups. Endocan levels did not correlate with fasting blood glucose, 2-h OGTT, A1C and lipid parameters. Multiple linear regression analysis revealed that endocan is an independent predictor for cIMT (β = 0.128, 95% CI = 0.118-0.138, P = 0.011). CONCLUSIONS Circulating endocan levels are significantly higher in women with PCOS and endocan is independently associated with cIMT. Elevated endocan levels can be a predictor of increased cardiovascular risk in PCOS subjects.

Abstract
BACKGROUND The objectives of the present study were to compare the effect of adjuvant chemotherapy for breast cancer on serum insulin levels, serum leptin levels, and body composition in early stage breast cancer patients. MATERIALS AND METHODS 17 breast cancer patients underwent 6 cycles of docetaxel (75 mg), epirubicine (100 mg) and cyclophosphamide (500 mg) (TEC). Anthropometrical and foot-to-foot body fat analyzer BIA, serum glucose, insulin, lipids, HOMA-IR and leptin were compared pre- and post-treatment. RESULTS There was no statistically significant weight gain after treatment; however, there was an overall trend toward weight gain (69.7 ± 9.8 kg vs 71.03 ± 9.8; P= 0.05). From baseline to the end of the study, percentage of body fat and body fat mass showed an upward trend at the end of chemotherapy (1%; 2 kg P> 0.05). Pre and post-treatment period, leptin was strongly correlated with insulin and HOMA-IR (Spearman's pre-T; r = 0.74; P <0.001, r = 0.66; P = 0.004 post-T; r = 0.549; P =0.022, r = 0.51; P =0.036, respectively). Insulin levels were significantly increased in the post-treatment period (P < 0.05). On correlation analysis, post-T insulin levels were correlated with leptin, weight, fat-mass and fat percentage (Spearman's r = 0.549; P=.022, r = 0.567; P= 0.018, r = 0.498, P= 0.042, r = 0.502; P= 0.040, respectively). DISCUSSION High insulin and leptin levels, important factors that were previously shown to be related to breast cancer outcome, and insulin resistance may be increased in taxane based chemotherapy regimen. These data may have broad implications for diet and lifestyle strategies for the prevention and treatment of cancers.

Abstract
BACKGROUND Kallistatin is a secreted protein that acts as a tissue kallikrein inhibitor. It has anti-inflammatory, antioxidant and vasoprotective properties. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease associated with low-grade chronic inflammation and multiple risk factors for cardiovascular diseases. The aims of this study were to ascertain whether circulating kallistatin levels are altered in women with PCOS, and whether there is an association between kallistatin and carotid intima-media thickness (cIMT) as well as inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α). METHODS This cross-sectional study included 75 women with PCOS and 75 age- and BMI-matched controls without PCOS. Circulating kallistatin and TNF-α levels were measured using ELISA. Metabolic and hormonal parameters, hs-CRP levels and cIMT were also determined. All subjects underwent the 2-hour oral glucose tolerance test (2-h OGTT). RESULTS Circulating kallistatin levels were significantly elevated in women with PCOS compared to controls (6.31±2.09 vs. 4.79±2.26 ng/mL, P<0.001). Inflammatory markers hs-CRP and TNF-α were found to be elevated in women with PCOS. Kallistatin levels positively correlated with insulin, insulin resistance index (HOMA-IR), free androgen index, hs-CRP, TNF-α and cIMT in both PCOS and control groups. Kallistatin levels did not show correlation with BMI, blood pressure, fasting blood glucose, 2-h OGTT or HbA1c. Multiple linear regression analysis revealed that kallistatin is an independent predictor for cIMT (β=0.131, 95% CI: 0.114-0.150, P=0.019). CONCLUSIONS Kallistatin levels may provide useful information regarding cardiovascular risk in women with PCOS.

Abstract
Fever of unknown origin is a rare condition after solid organ transplant and is generally associated with atypical infections (eg, tuberculosis, fungal infections) and/or lymphoproliferative disorders. Here, we present a kidney transplant patient with a late diagnosis of E148Q mutation-positive familial Mediterranean fever as the cause of fever of unknown origin. A 22-year-old female patient with a previous history of 4 years of hemodialysis and unknown primary renal disease received a deceased-donor kidney transplant at our center 5 years previously. She had an uneventful course in the first 3 years following transplant. After this period, she was hospitalized 3 times during a 4-month period with fever, nausea, vomiting, and atypical abdominal pain. At that time, hemogram results were unremarkable, except for mild leukocytosis and slightly elevated acute-phase reactants; blood, urine, and throat cultures were negative, and there were no remarkable findings on imaging tests. Fever was controlled within 48 hours by administering empiric ampicillin-sulbactam therapy and discontinuing immunosuppressive treatment except steroids. Three successive hospital admissions owing to similar complaints suggested periodic fever syndrome, and therapy with 1 g/day colchicine led to an excellent clinical response with no recurrence of fever or other symptoms. An FMF gene mutation analysis revealed heterozygous E148Q mutation positivity. Continuing the current treatment regimen, the patient did well during at approximately 1.5 years of follow-up. In the Mediterranean region population, familial Mediterranean fever should be considered in the diagnosis of fever of unknown origin in patients who have undergone renal transplant. E148Q mutation-positive familial Mediterranean fever has a subclinical course and renal manifestations that differ from AA amyloidosis during childhood and may be responsible for de novo familial Mediterranean fever after renal transplantation.

Abstract
BACKGROUND Receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPN) are soluble members of the tumor necrosis factor superfamily. Growing evidence suggest that there is link between inflammation, insulin resistance and OPG, soluble RANKL (sRANKL). We aimed to ascertain whether OPG and sRANKL levels are altered in prediabetic subjects and there is association between OPG/sRANKL and metabolic parameters. METHODS Forty prediabetic subjects and 40 age- and BMI-matched controls were recruited for this cross-sectional study. Circulating OPG, sRANKL were measured using ELISA. Anthropometric and metabolic parameters were also determined. RESULTS Circulating sRANKL (97.74±17.67 vs. 55.00±11.19 pg/mL, P=0.010) and OPG (261.54±74.55 vs. 159.23±52.91 pg/mL, P=0.020) levels were found to be significantly higher in diabetic subjects compared with control subjects. There was a positive correlation between sRANKL and OPG. sRANKL also positively correlated with BMI, insulin resistance marker HOMA-IR, inflammatory marker hs-CRP. Logistic regression analyses revealed that the odds ratio was increased for prediabetes in subjects with having elevated sRANKL levels. CONCLUSIONS Increased sRANKL and OPG levels were associated with prediabetic subjects. sRANKL and OPG may play a role in the pathogenesis of diabetes as well as metabolic disturbance.

Abstract
CONTEXT Adipsin, a protein secreted mainly from the adipose tissue, is a structural homologous of complement factor D, a rate-limiting enzyme of the alternative complement system. Growing evidence suggests that the alternative complement system plays a role both in the regulation of energy homoeostasis and in the atherosclerosis. Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disease. OBJECTIVE To ascertain whether circulating adipsin levels are altered in women with PCOS, and whether there is an association between adipsin and metabolic parameters or carotid intima media thickness (CIMT). PARTICIPANTS A total of 144 women with PCOS and 144 age- and BMI-matched controls without PCOS were recruited for this cross-sectional study. MAIN OUTCOME MEASURES Circulating adipsin levels were measured using ELISA. Metabolic, hormonal parameters and CIMT were also determined. RESULTS Adipsin levels were significantly elevated in women with PCOS compared with controls (91·52 ± 14·11 vs 60·31 ± 9·71 ng/ml, P < 0·001). Adipsin positively correlated with BMI, homoeostasis model assessment of insulin resistance (HOMA-IR), free testosterone, high-sensitivity C-reactive protein (hs-CRP) and CIMT in both groups. Multivariate logistic regression analyses revealed that the odds ratio for PCOS was 3·25 for patients in the highest quartile of adipsin compared with those in the lowest quartile (OR=3·25, 95% CI=2·64-4·00, P = 0·016). Our findings further indicate that BMI, HOMA-IR, hs-CRP and free testosterone are independent factors influencing serum adipsin levels and that adipsin is an independent predictor for CIMT. CONCLUSION Circulating adipsin levels are significantly higher in women with PCOS, and the peptide is closely related to increased cardiovascular risk and metabolic disturbances.

Abstract
BACKGROUND To evaluate the macrophage migration inhibitory factor and E-selectin levels in patients with acute coronary syndrome. MATERIALS/METHODS We examined the plasma migration inhibitory factor and E-selectin levels in 87 patients who presented with chest pain at our hospital. The patients were classified into two groups according to their cardiac status. Sixty-five patients had acute myocardial infarction, and 22 patients had non-cardiac chest pain (non-coronary disease). We designated the latter group of patients as the control group. The patients who presented with acute myocardial infarction were further divided into two subgroups: ST-elevated myocardial infarction (n = 30) and non-ST elevated myocardial infarction (n = 35). RESULTS We found higher plasma migration inhibitory factor levels in both acute myocardial infarction subgroups than in the control group. However, the E-selectin levels were similar between the acute myocardial infarction and control patients. In addition, we did not find a significant difference in the plasma migration inhibitory factor levels between the ST elevated myocardial infarction and NST-elevated myocardial infarction subgroups. DISCUSSION The circulating concentrations of migration inhibitory factor were significantly increased in acute myocardial infarction patients, whereas the soluble E-selectin levels were similar between acute myocardial infarction patients and control subjects. Our results suggest that migration inhibitory factor may play a role in the atherosclerotic process.

Abstract
PURPOSE The hormone fibroblast growth factor 21 (FGF-21) regulates carbohydrate and lipid homeostasis. FGF-21 represents an attractive novel therapy for obesity since administration of FGF-21 has been shown to improve metabolic abnormalities in obese animal models. We investigated FGF-21 and its relationship with epicardial fat thickness (EFT), metabolic parameters, and inflammatory markers in premenopausal obese women compared to controls with similar Systematic Coronary Risk Evaluation (SCORE) project risk profiles. METHODS Forty-five obese premenopausal women with body mass index (BMI) ≥30 kg/m(2) and 41 control premenopausal women with BMI <25 kg/m(2) with similar SCORE project risk profiles were included in this case-control study. EFT was evaluated by two-dimensional transthoracic echocardiography. Serum FGF-21 was measured with an ELISA kit. RESULTS FGF-21 and EFT were significantly higher in obese women compared to controls (p < 0.001). Multiple stepwise linear regression analysis showed that EFT, BMI, and triglycerides (TG) independently contributed to FGF-21 (R(2) = 0.757, p < 0.001). However, homeostasis model assessment of insulin resistance (HOMA-IR), visceral ectopic fat, and inflammatory markers were not found as a direct contributor to serum FGF-21 level (p > 0.05). CONCLUSIONS EFT, BMI, and TG may play an important role in predicting serum FGF-21 level which may be a potential therapeutic target in cardiometabolic disorders in the future.

Abstract
BACKGROUND/AIM Galectins affect diverse physiological and pathophysiological processes such as development, inflammation, and tumor growth. We aimed to compare serum galectin-3 levels in three patient groups with chronic hepatitis B and C virus (HBV, HCV), cirrhosis secondary to HBV or HCV, and hepatocellular carcinoma (HCC) secondary to HBV or HCV and evaluate the role of galectin-3 during HCC progression. PATIENTS AND METHODS Nineteen patients with hepatocellular cancer, 22 patients with cirrhosis, and 24 patients with chronic hepatitis B and C were included in this study. Serum galectin-3 levels in different liver diseases were assessed by enzyme-linked immunosorbent assay. RESULTS The mean galectin-3 levels were 4.61 ng/mL (±2.32) in HCC patients, 5.68 ng/mL (±2,2) in cirrhotic patients, 1.98 ng/mL (±1.50) in chronic viral hepatitis group. There were no statistical differences between HCC and cirrhotic patients (P = 0.5), but lower in chronic hepatitis group statistically compared with cirrhosis and HCC (P < 0.001, P = 0.002, respectively). In case of cirrhotic patients, galectin-3 levels were significantly higher in patients with cirrhosis secondary to HCV compared with HBV (P = 0.03). When we evaluated galectin-3 levels in HCC patients, it was found to be 3.92 ng/mL in HCC secondary to hepatitis B and 5.37 ng/mL in HCC secondary to hepatitis C. CONCLUSION Serum galectin-3 levels in patients with chronic HBV or HCV may guide us about progression to cirrhosis or HCC and prognosis of the disease. Especially, galectin-3 levels may be more pronounced in case of HCV.

Abstract
Objective: Immunoglobulin free light chain (FLC) abnormalities are common in patients with monoclonal gammopathies and the kidneys are the most affected organs. Immunoassays that provide quantitative measurement of FLC in serum indicate monoclonal FLC production based on the presence of an abnormal FLC kappa:lambda (κ:λ) ratio. The aim of this study was to assess the utility of serum FLC measurement as a diagnostic tool for detecting plasma cell dyscrasias in comparison to standard assays, and to ascertain its sensitivity and specificity in patients with acute renal failure (ARF). Material and Methods: Sera from 82 patients with ARF were assessed using serum protein electrophoresis (SPE), serum immunofixation electrophoresis (SIFE), and FLC measurement. The sensitivity and specificity of the FLC ratio in identifying which ARF patients had multiple myeloma (MM) was compared to those of SPE and SIFE. Results: Among the 82 patients with ARF, 7 were diagnosed as MM using SPE, SIFE, and bone marrow biopsy techniques. In total, 8 patients did not have a FLC κ:λ ratio that was within the published reference range (0:26-1:65); the FLC κ:λ ratio based on FLC measurement had a specificity of 96% and sensitivity of 71%, and positive and negative predictive values of 62.9% and 97.3%, respectively, for the diagnosis of MM. Conclusion: The sensitivity and specificity of the FLC κ:λ ratio for diagnosing MM in patients that presented with ARF were lower than those of SPE and SIFE. To further delineate the utility of the FLC κ:λ ratio additional prospective, well-designed large-scale studies are needed. Conflict of interest:None declared.

Abstract
PURPOSE The present study was undertaken to evaluate the effects of adjuvant anthracycline-based chemotherapy on thiobarbituric acid reactive substances (TBARS) and superoxide dismutase (SOD) levels in patients with breast cancer who had undergone surgery. METHODS Body mass index (BMI), serum lipids (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides), serum TBARS and SOD values were assessed in 30 patients with stage III breast cancer receiving adjuvant anthracycline- based chemotherapy. RESULTS Anthracycline-based chemotherapy had no effect on BMI, blood pressure and lipid profile. A significant elevation was noted in TBARS (5.5±0.6 vs 5.9±0.9 μmol/L; p=0.038) and a significant reduction to baseline values in SOD levels (226.5±61.0 vs 203.1±48.3 U/mL; p=0.03) in patients following 6 cycles of adjuvant chemotherapy. CONCLUSION The TBARS levels increased, whereas the SOD levels descreased after anthracycline-based chemotherapy. We suggest that oxidative stress is not always detrimental, as it can be beneficial in cancer treatment.

Abstract
OBJECTIVE Nitric oxide is produced by endothelial nitric oxide synthase, and its production can be influenced by polymorphisms of the endothelial nitric oxide synthase gene. Because candidate genes responsible for susceptibility to ankylosing spondylitis are mostly unknown and available data suggest that there may be problems related to the nitric oxide pathway, such as endothelial dysfunction and increased asymmetric dimethylarginine, this study aimed to assess the association of common endothelial nitric oxide synthase gene polymorphisms with ankylosing spondylitis. METHODS One hundred ninety-four unrelated Turkish ankylosing spondylitis patients and 113 healthy without apparent cardiovascular disease, hypertension or diabetes mellitus were included. All individuals were genotyped by PCR-RFLP for two single-nucleotide polymorphisms, namely 786T>C (rs2070744, promoter region) and 786 Glu298Asp (rs1799983, exon 7). Variable numbers of tandem repeat polymorphisms in intron 4 were also studied and investigated by direct electrophoresis on agarose gel following polymerase chain reaction analysis. The Bath ankylosing spondylitis metrology index of the patients was calculated, and human leukocyte antigen B27 was studied. RESULTS All studied polymorphisms satisfied Hardy-Weinberg equilibrium. Sex distributions were similar between the patient and control groups. No significant differences were found in the distributions of allele and genotype frequencies of the studied endothelial nitric oxide synthase polymorphisms between patients and controls. There were no correlations between endothelial nitric oxide synthase polymorphisms, disease duration, Bath ankylosing spondylitis metrology index or human leukocyte antigen B27. CONCLUSION The results presented in this study do not support a major role of common endothelial nitric oxide synthase polymorphisms in Turkish ankylosing spondylitis patients.

Abstract
Background Hepatocyte growth factor (HGF) induced c-Met activation is known as the main stimulus for hepatocyte proliferation and is essential for liver development and regeneration. Activation of HGF/c-Met signaling has been correlated with aggressive phenotype and poor prognosis in hepatocellular carcinoma (HCC). MUC1 is a transmembrane mucin, whose over-expression is reported in most cancers. Many of the oncogenic effects of MUC1 are believed to occur through the interaction of MUC1 with signaling molecules. To clarify the role of MUC1 in HGF/c-Met signaling, we determined whether MUC1 and c-Met interact cooperatively and what their role(s) is in hepatocarcinogenesis. Results MUC1 and c-Met over-expression levels were determined in highly motile and invasive, mesenchymal-like HCC cell lines, and in serial sections of cirrhotic and HCC tissues, and these levels were compared to those in normal liver tissues. Co-expression of both c-Met and MUC1 was found to be associated with the differentiation status of HCC. We further demonstrated an interaction between c-Met and MUC1 in HCC cells. HGF-induced c-Met phosphorylation decreased this interaction, and down-regulated MUC1 expression. Inhibition of c-Met activation restored HGF-mediated MUC1 down-regulation, and decreased the migratory and invasive abilities of HCC cells via inhibition of β-catenin activation and c-Myc expression. In contrast, siRNA silencing of MUC1 increased HGF-induced c-Met activation and HGF-induced cell motility and invasion. Conclusions These findings indicate that the crosstalk between MUC1 and c-Met in HCC could provide an advantage for invasion to HCC cells through the β-catenin/c-Myc pathway. Thus, MUC1 and c-Met could serve as potential therapeutic targets in HCC.

Abstract
BACKGROUND The purpose of this study is to determine the levels of procalcitonin (PCT), IL-8 (interleukin-8), MIF (macrophage migration inhibitory factor), osteoprotegerin (OPG), hs-CRP and D-dimer during fever above 38.3°C due to various causes. MATERIAL AND METHODS Blood samples taken from a total of consecutive 65 hospitalized patients during fever were prospectively tested for hsCRP, PCT, IL-8, OPG, MIF and D-dimer. Of these patients, there were 26 patients presenting with chemotherapy-induced neutropenia who had no infectious agents found; 23 patients, who had a malignancy with a febrile episode which was neither a microbiologically documented infection nor a chemotherapy-induced neutropenia, and 16 patients who did not have a malignancy and were considered to have a clinically and microbiologically documented infection. RESULTS IL-8 and D-dimer levels were higher in patients with febrile neutropenia than in the other two groups. Although MIF and OPG were higher in patients with newly diagnosed cancers, there were no differences among the three groups regarding PCT and hs-CRP values. CONCLUSION High serum IL-8 and D-dimer levels can be useful markers to identify hospitalized chemotherapy-induced neutropenia patients. MIF and OPG were found to be higher in patients with newly diagnosed cancer.

STUDY DESIGN A total of 69 women, 32 with POF and 37 apparently healthy women were included in the study. Fasting blood samples were drawn to measure serum homocysteine and ADMA levels using ELISA method. RESULTS The study and control group had a mean age of 37.3 + 2.6, 37.5 + 2.5 years; a mean homocysteine level of 13.54 + 5.19, 12.71 + 3.99 mmol/l and a mean ADMA level of 1.32 + 0.27, 1.26 + 0.36 mmol/l, respectively. There were no statistically significant differences between the two groups in terms of homocysteine and ADMA levels (with p values of 0.465 and 0.423, respectively). A negative significant correlation was found between estradiol and ADMA (p <0.05). CONCLUSION Homocysteine and ADMA levels did not change in comparison with the control group, which suggests that estrogen deficiency in patients with POF does not have any effect on homocysteine and asymmetric dimethylarginine levels.

Abstract
BACKGROUND Splenectomy is a treatment procedure for ITP which is being used for more that 50years and is still considered as the best option for the treatment of the condition. The facts that frequent monitoring is not required and that medical treatment is not indicated following splenectomy in most cases are among the major advantages of the procedure. AIM OF THE STUDY To compare the conventional dose steroid and high dose steroid treatments as run-in regime for splenectomy in patients diagnosed with ITP. METHODS The conventional dose steroid (1mg/kg, n=20) and high dose steroid treatments (30mg/kg, n=30) were applied to 50 cases with ITP between 1998 and 2008 in our clinic. RESULTS High dose steroid produced higher platelet count on days 3, 5, and 7 compared to conventional dose steroid. There were no differences between the groups in terms of adverse effects. Treatments were discontinued after the operation by rapidly reducing the dose. Postoperative values regarding response to splenectomy were comparable in both groups. CONCLUSIONS Both higher and earlier responses obtained with high dose steroid may be significant in reducing hospitalization period of patients and eliminating life-threatening platelet values within the shortest time possible.

Abstract
AIM To evaluate sCD40L levels in women with polycystic ovary syndrome (PCOS) who use combination therapy with metformin and oral contraceptives. METHODS Total of 60 patients with PCOS was studied to evaluate and compare with a non-PCOS group consisting of 30 subjects. A low-dose oral contraceptive containing ethinyl oestradiol-cyproterone acetate (EE/CA) and metformin (M; 850 mg metformin twice a day) were given for three cycles. Plasma sCD40L was measured before and after the treatment of 3 months. RESULTS At baseline, the sCD40L levels of the patients with PCOS was significantly higher than those of control subjects (3.1 ± 2.0 vs. 2.05 ± 1.0, respectively; p=0.002). An average of 3 months of EE/CA-M therapy induced a significant decrease of sCD40L levels in the PCOS group (3.1 ± 2.0 vs. 2.5 ± 1.0; p=0.026). After having treated patients with PCOS, the sCD40L level was not completely normalised when compared to the healthy controls (2.5 ± 1.0 vs. 2.05 ± 1.0; p=0.039). CONCLUSIONS PCOS is associated with elevated levels of sCD40L. Adding metformin therapy to EE/CA may decrease sCD40L levels in women PCOS. However, after the treatment for PCOS subjects, the sCD40L was not completely normalised when compared patients to healthy controls.

Abstract
The present study was aimed to determine the effect of iron supplementation on levels of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in patients with iron deficiency anemia (IDA). In this study, 26 female patients diagnosed with iron deficiency were treated approximately 3 months of oral iron supplementation (99 ± 10 days; ferrous glycine sulfate; 100 mg/day of elemental iron). Levels of sICAM-1 and sVCAM-1 were assessed prior to treatment and after approximately 3 months of treatment and compared with 26 healthy female subjects. A significant increase in sVCAM levels was found in the patients with iron deficiency at the end of the treatment relative to pretreatment levels compared to controls, whereas no significant differences were determined in sICAM levels. In the posttreatment period, no significant change was observed in sICAM levels compared to the pretreatment levels, whereas sVCAM levels decreased. However, after the treatment period, the sVCAM, hemoglobin, mean corpuscular volume (MCV), and serum ferritin levels did not return to the normal range compared to the controls. Pretreatment sVCAM-1 levels were inversely correlated with levels of hemoglobin, hemotocrit, MCV, serum iron, and ferritin. After treatment, the sVCAM-1 levels were negatively correlated with ferritin levels. Levels of sVCAM were significantly higher in patients with IDA than controls. After the treatment period, the sVCAM levels were not completely normalized in patients with IDA compared to controls, regardless of the presence of inadequate levels of hemoglobin, MCV, and serum ferritin. Thus, iron supplementation not only ameliorates anemia, but may also reduce the inflammation markers in cases with IDA.

Abstract
OBJECTIVES To determine the effect of Helicobacter pylori (H. pylori) eradication on blood levels of high-sensitivity C-reactive protein (hs-CRP), macrophage migration inhibitory factor and fetuin-A in patients with dyspepsia who are concurrently infected with H. pylori. METHODS H.pylori infection was diagnosed based on the 14C urea breath test (UBT) and histology. Lansoprazole 30 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily were given to all infected patients for 14 days; 14C UBT was then re-measured. In 30 subjects, migration inhibitory factor, fetuin-A and hs-CRP levels were examined before and after the eradication of H. pylori infection and compared to levels in 30 healthy subjects who tested negative for H. pylori infection. RESULTS Age and sex distribution were comparable between patients and controls. Migration inhibitory factor and hs-CRP levels were higher, and fetuin-A levels were lower, in H. pylori-infected patients (p<0.05). Following eradication of H. pylori, migration inhibitory factor and hs-CRP levels were significantly decreased, whereas fetuin-A levels were increased. However, eradication of the organism did not change lipid levels (p>0.05). CONCLUSION These findings suggest that H. pylori eradication reduces the levels of pro-inflammatory cytokines such as migration inhibitory factor and hs-CRP and also results in a significant increase in anti-inflammatory markers such as fetuin-A.

Abstract
PURPOSE To evaluate the levels of asymmetric dimethylarginine (ADMA), an endothelin and nitric oxide (NO) synthase inhibitor, in patients with node-positive breast cancer who had undergone surgery and in a control group including healthy individuals. The effects of taxane-based chemotherapy on endothelin-1 (ET-1) and ADMA levels in the patient group were also studied. METHODS Body mass index (BMI), serum lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides), ADMA and ET-1 were studied in 19 healthy individuals and in 19 patients with stage II and III, lymph node-positive breast cancer receiving taxane-based chemotherapy. RESULTS ET-1 (34.3±12.8 vs. 13.8±4.5 pg/mL; p<0.001) and ADMA (0.87±0.18 vs. 0.68±0.24 μmol/L; p=0.024) levels were significantly higher in the breast cancer group compared to the control group. A significant reduction was noted in ET-1 (34.3±12.8 vs. 27.3±4.3 pg/mL; p=0.021) and ADMA (0.87±0.18 vs. 0.73±0.15 μmol/L; p=0.014) levels in patients following 6 cycles of adjuvant chemotherapy to baseline values. CONCLUSION The present study demonstrated significantly higher levels of ET-1 and ADMA in the breast cancer group compared to the control group, which were reduced significantly with adjuvant taxane-based chemotherapy. It is apparent that prospective studies are needed to understand the effect of reducing ET-1 and ADMA levels on patient survival. We believe that the present study will provide guidance to relevant future studies.

Abstract
BACKGROUND To analyze Fetuin-A levels and soluble cellular adhesion molecules in patients with acute coronary syndrome. METHODS AND RESULTS Serum Fetuin-A and intercellular adhesion molecule-1 (sICAM-1), vascular cellular adhesion molecule-1 (sVCAM-1) levels were examined in 127 patients who presented with chest pain. These patients were classified in three groups: stable angina (SA, n=51), myocardial infarction (MI, n=34) and non-cardiac group (n=42). Logarithmic transformations were made for Fetuin-A levels. Log-Fetuin-A levels were higher in non-cardiac subjects compared to MI and SA patients (p<0.05). Patients with SA showed lower levels than controls but higher levels as compared to MI patients. After controlling for age and gender, levels of sVCAM-1 and sICAM-1 in patients with coronary atherosclerosis were not different from those in non-cardiac subjects. CONCLUSION Serum levels of soluble VCAM-1, ICAM-1 were not related to coronary artery disease (CAD), but fetuin-A levels seems to be decreased in SA and MI patients. Low fetuin-A may play a role in the pathophysiology of CAD.
