Abstract
A comprehensive analysis of site-specific protein O-glycosylation is hindered by the absence of a consensus O-glycosylation motif, the diversity of O-glycan structures, and the lack of a universal enzyme that cleaves attached O-glycans. Here, we report the development of a robust O-glycoproteomic workflow for analyzing complex biological samples by combining four different strategies: removal of N-glycans, complementary digestion using O-glycoprotease (IMPa) with/without another protease, glycopeptide enrichment, and mass spectrometry with fragmentation of glycopeptides using stepped collision energy. Using this workflow, we cataloged 474 O-glycopeptides on 189 O-glycosites derived from 79 O-glycoproteins from human plasma. These data revealed O-glycosylation of several abundant proteins that have not been previously reported. Because many of the proteins that contained unannotated O-glycosylation sites have been extensively studied, we wished to confirm glycosylation at these sites in a targeted fashion. Thus, we analyzed selected purified proteins (kininogen-1, fetuin-A, fibrinogen, apolipoprotein E, and plasminogen) in independent experiments and validated the previously unknown O-glycosites.

Abstract
UNLABELLED Calciprotein particles (CPP) are nanoscale mineralo-protein aggregates that help stabilize excess mineral in the circulation. We examined the relationship between CPP and bone mineral density in Fabry disease patients. We found an inverse correlation with total hip and femoral neck density, but none with lumbar spine. PURPOSE Calciprotein particles (CPP) are colloidal mineral-protein complexes made up primarily of the circulating glycoprotein fetuin-A, calcium, and phosphate. They form in extracellular fluid and facilitate the stabilization, transport, and clearance of excess minerals from the circulation. While most are monomers, they also exist in larger primary (CPP-I) and secondary (CPP-II) form, both of which are reported to be raised in pathological states. This study sought to investigate CPP levels in the serum of patients with Fabry disease, an X-linked systemic lysosomal storage disorder that is associated with generalized inflammation and low bone mineral density (BMD). METHODS We compared serum CPP-I and CPP-II levels in 59 patients with Fabry disease (37 female) with levels in an age-matched healthy adult cohort (n=28) and evaluated their association with BMD and biochemical data obtained from routine clinical review. RESULTS CPP-I and CPP-II levels were higher in male Fabry disease patients than female sufferers as well as their corresponding sex- and age-matched controls. CPP-II levels were inversely correlated with BMD at the total hip and femoral neck, but not the lumbar spine. Regression analyses revealed that these associations were independent of common determinants of BMD, but at the femoral neck, a significant association was only found in female patients. CONCLUSION Low hip BMD was associated with high CPP-II in patients with Fabry disease, but further work is needed to investigate the relevance of sex-related differences and to establish whether CPP measurement may aid assessment of bone disease in this setting.

Abstract
BACKGROUND Calcific aortic valve disease (CAVD) has a substantial and increasing burden in the ageing population with occult onset.Present study aimed to assess association of clinical characteristics of these patients and occurrence of CAVD. METHODS Patients diagnosed with CAVD and those receiving healthy medical examination in our hospital from January 2019 to February 2021 were enrolled in this retrospective study. Clinical characteristics, ultrasonic indicators, serological indicators and histology of CAVD were collected and compared among different groups. Logistic regression and Pearson correlation analysis was used to explore relationship between these indexes and occurrence of CAVD. RESULTS DBP, SBP, LVESD, LVEDD, IVS, PW, AV Vmax, TC, TG, LDL-C, Fetuin-A, Lp(a) in severe group were higher than mild, moderate and control groups (P<0.05), while those indexes of patients in moderate group were higher than that in mild and controlled groups (P<0.05). Besides, theses indexes of patients in mild group were also higher than that of controlled one (P<0.05). However, LVEF, HDL-C and MGP of patients in severe group was the lowest (P<0.05), while those in moderate group were lower than mild and controlled groups. Moreover, these indexes in mild group were also lower than control group (P<0.05). In Logistic regression analysis, MGP, Fetuin-A and Lp(a) were all independently associated with occurrence of CAVD (P<0.05). In Pearson correlation analysis, Fetuin-A and Lp(a) were positively correlated with progression of the disease, while MGP and macrophage density were negatively correlated with it. CONCLUSIONS Fetuin-A, MPG and Lp(a) were independently associated with the occurrence of CAVD, and they might be potential predictors for diagnosis of this disease.

Abstract
BACKGROUND Fetuin-A is a hepatokine which has the capacity to prevent vascular calcification. Moreover, it is linked to the induction of metabolic dysfunction, insulin resistance and associated with increased risk of diabetes. It has not been clarified whether fetuin-A associates with risk of vascular, specifically microvascular, complications in patients with diabetes. We aimed to investigate whether pre-diagnostic plasma fetuin-A is associated with risk of complications once diabetes develops. METHODS Participants with incident type 2 diabetes and free of micro- and macrovascular disease from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam cohort (n = 587) were followed for microvascular and macrovascular complications (n = 203 and n = 60, respectively, median follow-up: 13 years). Plasma fetuin-A was measured approximately 4 years prior to diabetes diagnosis. Prospective associations between baseline fetuin-A and risk of complications were assessed with Cox regression. RESULTS In multivariable models, fetuin-A was linearly inversely associated with incident total and microvascular complications, hazard ratio (HR, 95% CI) per standard deviation (SD) increase: 0.86 (0.74; 0.99) for total, 0.84 (0.71; 0.98) for microvascular and 0.92 (0.68; 1.24) for macrovascular complications. After additional adjustment for cardiometabolic plasma biomarkers, including triglycerides and high-density lipoprotein, the associations were slightly attenuated: 0.88 (0.75; 1.02) for total, 0.85 (0.72; 1.01) for microvascular and 0.95 (0.67; 1.34) for macrovascular complications. No interaction by sex could be observed (p > 0.10 for all endpoints). CONCLUSIONS Our data show that lower plasma fetuin-A levels measured prior to the diagnosis of diabetes may be etiologically implicated in the development of diabetes-associated microvascular disease.

Abstract
Fetuin-A plays an important role in antivascular calcification and inflammatory response, it is necessary to explore the relationship between fetuin-A and coronary atherosclerotic heart disease (CHD) and CHD-related risk factors.A total of 92 patients with CHD as the research group, and 60 healthy persons as the control group were enrolled from May 2019 to May 2020. Fetuin-A levels were determined by enzyme-linked immunosorbent assay, and the characteristics and clinical data were collected and compared. Logistic regression was used to analyze the factors influencing CHD.The age, proportion of males, patients with hypertension and diabetes, as well as fetuin-A level in the research group were significantly higher than those in the control group, but the high-density lipoprotein cholesterol level was significantly lower than that in the control group (P < .05). Logistic regression analysis and correction showed that gender, age, blood pressure, and diabetes were related to the onset of CHD, and there was a significant correlation between the level of fetuin-A and age (P < .05).Serum fetuin-A was related to the onset risk of CHD, and showed a significant correlation with age.

Abstract
BACKGROUND AND AIMS Atherosclerotic calcification is a powerful predictor of cardiovascular disease. This study aims to determine whether circulating levels of a local/systemic calcification inhibitor or a marker of bone formation correlate with measures of coronary or extracoronary calcification. METHODS AND RESULTS Clinical computed tomography (CT) was performed on 64 arterial disease participants undergoing carotid and lower extremity endarterectomy. Coronary artery calcium (CAC) scores and volumes were acquired from the CT scans (n = 42). CAC scores and volumes were used to derive CAC density scores. Micro-CT was performed on excised carotid (n = 36) and lower extremity (n = 31) plaques to quantify the volume and volume fraction of extracoronary calcification. Circulating levels of dephospho-uncarboxylated Matrix Gla Protein (dp-ucMGP), fetuin-A, carboxylated and uncarboxylated osteocalcin (ucOC) were quantified using commercial immunoassays. Carotid participant CAC density scores were moderately negatively correlated with plasma dp-ucMGP (rs = -0.592, P = 0.008). A weak negative association was found between CAC scores and %ucOC for all participants (rs = -0.335, P = 0.040). Another weak negative correlation was observed between fetuin-A and the volume of calcification within excised carotid specimens (rs = -0.366, P = 0.031). Despite substantial differences in coronary and extracoronary calcium measurements, the levels of circulating biomarkers did not vary significantly between carotid and lower extremity subgroups. CONCLUSION Correlations identified between circulating biomarkers and measures of coronary and extracoronary calcium were not consistent among participant subgroups. Further research is required to determine the association between circulating biomarkers, coronary and extracoronary calcium.

Abstract
PURPOSE The hepatokine fetuin-A might have a role as molecular link between non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM). The aim of this study was to evaluate the association between fetuin-A and the prevalence and severity of NAFLD in a population of young adults. METHODS Ninety-seven adults (age 35.7 ± 12.4 years, female 64.9%), enrolled in a previous study evaluating NAFLD prevalence in the presence or absence of family history of T2DM, were included. Serum levels of fetuin-A (ELISA BioVendor, Czech Republic) and the main biochemical parameters were assessed. Presence and severity of NAFLD were evaluated by ultrasonography (Toshiba, Japan). A linear regression was run to predict fetuin-A levels and a logistic regression was performed to predict moderate-severe steatosis. RESULTS Fetuin-A associated inversely with age (ß - 0.12, p = 0.03) and directly with body mass index (BMI) (ß 0.5, p = 0.048), waist circumference (WC) (ß 0.3, p = 0.027), triglycerides (TG) (ß 0.1, p = 0.001) and uric acid (ß 1.7, p = 0.018), after adjustment for age and sex. In a model including age, BMI, WC, TG and uric acid, age (ß - 0.2, p = 0.002) and TG (ß 0.04, p = 0.02) were independent predictors of fetuin-A. Prevalence of steatosis was 66%. The rates of mild and moderate-severe steatosis were 50.5% and 15.5%, respectively. In the logistic model, the independent predictors of moderate-severe steatosis were fetuin-A (OR 1.22, p = 0.036), age (OR 1.17, p = 0.01) and BMI (OR 2.75, p = 0.011). CONCLUSION In a sample of young adults, circulating levels of fetuin-A correlated with moderate-severe NAFLD, independent of confounders, and with some metabolic parameters. Fetuin-A might be a useful marker to predict NAFLD and metabolic disorders.

Abstract
BACKGROUND Evaluating the impact of chromium picolinate supplementation on glycemic status, lipid profile, inflammatory markers and fetuin-A in patients with non-alcoholic fatty liver disease (NAFLD). METHODS In present research, participants (N = 46) were randomized to (400 mcg/day, n = 23) chromium picolinate and placebo (n = 23) for 3 months. RESULTS Glucose indices, and lipid profiles, inflammatory biomarker and fetuin-A were measured before and after the intervention. Chromium reduced triglyceride (TG), atherogenic index of plasma (AIP), very-low-density lipoprotein (VLDL), insulin, homeostatic model assessment for insulin resistance (HOMA-IR), high-sensitivity C-reactive protein (hs-CRP), interleukin (IL) -6, tumor necrosis factor-alpha (TNF-α) and fetuin-A significantly compared to placebo group (p < 0.05). Furthermore, chromium significantly increased the quantitative insulin sensitivity check index (QUICKI). There were no significant differences in total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), fasting blood sugar (FBS), Hemoglobin A1c (HbA1C), interleukin (IL)-17 between the two groups (p < 0.05). CONCLUSION Chromium picolinate significantly decreased TG, insulin, HOMA-IR, fetuin-A, the number of inflammatory factors, and increased QUICKI without changing FBS, HbA1C, TC, LDL, HDL, IL-17 levels and liver steatosis intensity in patients with NAFLD. Further studies by examining the effect of different doses of chromium and mechanisms of cellular action, would help further clarify the subject.

Abstract
Animal data link high circulating fetuin-A to low insulin sensitivity and observational studies identify the hepatokine as a marker of future incident type 2 diabetes mellitus in humans. However, a recent, well-powered Mendelian randomization study finds no causal role. We therefore tested in a deeply-phenotyped human cohort if circulating fetuin-A correlates independently with insulin sensitivity and how it relates to the metabolic syndrome and ectopic fat deposition. We analyzed data from 290 young women with and without recent gestational diabetes mellitus. We found that circulating fetuin-A correlates inversely with insulin sensitivity in univariate analyses, but that this correlation is lost after adjustment for markers of the metabolic syndrome and of fatty liver. Additionally, we investigated which fat compartment associates most strongly with circulating fetuin-A. In whole body MRI data from a subcohort of 152 women, this was liver fat content. We conclude that high circulating fetuin-A occurs as part of the metabolic syndrome in young women and associates most strongly with liver fat content. Its close link to the metabolic syndrome may also cause the inverse correlation of circulating fetuin-A with insulin sensitivity as we found no independent association.

Abstract
Androgens play a pivotal role in non-reproductive organs such as the kidney, heart, liver, and pancreas. As androgen receptors are expressed in pancreatic and liver cells, excess testosterone can result in hypersecretion of insulin and fetuin-A, a protein produced in the liver. The expression of fetuin-A, a natural inhibitor of tyrosine kinase activity in muscle and liver, leads to insulin resistance. In addition, insulin and fetuin-A levels are thought to be affected by drugs such as glucocorticoids (GCs) and fludrocortisone. However, whether fetuin-A and insulin levels are affected by androgens and GCs in patients with classic congenital adrenal hyperplasia (CAH) is unknown. This cross-sectional study included 56 CAH patients and 70 controls. Analyses were stratified by sex and prepubertal/pubertal status to control for potential changes in serum metabolic/inflammatory markers associated with the production of sex steroids. Fasting blood glucose, insulin, triglyceride, total cholesterol, high density lipoprotein-cholesterol, aspartate aminotransferase, alanine aminotransferase, fetuin-A, and high-sensitivity C-reactive protein (hs-CRP) levels were measured in blood samples. In addition, 17α-hydroxyprogesterone, androstenedione, total testosterone, free testosterone, and dehydroepiandrosterone sulfate levels were measured before medication was administered. Insulin and fetuin-A levels were significantly higher in CAH patients than in controls. The unfavourably high levels of these substances exhibited a positive correlation with total and free testosterone. Regression analysis revealed that fetuin-A and free testosterone were the only independent predictors of the insulin level, while insulin and free testosterone levels significantly predicted the fetuin-A level (R2=42.7% and 59.8%). Differences were also observed in triglyceride and hs-CRP levels between the pubertal and prepubertal groups. We conclude that serum fetuin-A and insulin levels may be associated with androgens in CAH patients.

Abstract
Although mass spectrometry-based plasma proteomics enables sensitive and large-scale discovery and validation of biomarkers for various diseases, its integrative application to hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) is not well investigated. Therefore, we analyzed albumin- and immunoglobulin G-depleted plasma samples from 148 and 60 patients with HCC and CCA, respectively, using liquid chromatography-tandem mass spectrometry. The algorithm used to measure the content of each protein was the percentage of exponentially modified protein abundance index. From 5320 proteins assayed in plasma, 53 and 25 biomarker candidates were identified for HCC and CCA, respectively. The abundance of six and two HCC markers particularly protruded in stage II and III, respectively, whereas plasma serine protease inhibitor was the sole marker the level of which steadily decreased with CCA progression. From a prognostic facet, we showed candidate markers and their cutoff levels for evaluating probability of tumor recurrence and patient survival period. Combination Kaplan-Meier models showed that HCC stage III or IV and both the content of alpha-2-HS-glycoprotein and apolipoprotein CIII <0.2% exhibited the poorest post-surgical recurrence-free and overall survivals. Furthermore, the content of afamin ≥0.2% played a significant role on the poor prognosis in patients with CCA. Our findings, taken together, characterized novel plasma biomarker signatures in dissecting tumor stages and post-surgical outcomes of HCC and CCA.

Abstract
Objective Fetuin-A has been associated with the progression of metabolic syndrome, but previous studies found inconsistent results on the relationship between metabolic syndrome and the concentration of fetuin-A. The aim of this study was to perform a meta-analysis to summarize previous findings on this relationship. Method This study was registered with the International Prospective Register of Systematic Reviews PROSPERO (CRD42019129566). Studies examining the relationship between metabolic syndrome and the concentration of circulating fetuin-A were identified using a systematic search in the electronic databases of Embase, PubMed, Web of Science, and Cochrane Library before March 2019. A random effects model was used to summarize the effect size of the association in terms of the standardized mean difference (SMD). Results Fourteen eligible studies compared fetuin-A concentrations between 4,551 metabolic syndrome patients and 8,805 controls. The circulating fetuin-A concentration was significantly higher in the metabolic syndrome patients than in the controls (SMD = 0.65, 95% confidence interval (CI): 0.48 to 0.83, Z = 7.18, p<0.001). Besides, circulating fetuin-A was a risk factor for metabolic syndrome (odds ratio 1.23, 95% CI: 1.08 to 1.40). Conclusion These findings suggest that fetuin-A may be an important indicator for metabolic syndrome, in which case this may lead to new perspectives in early diagnosis, identification of novel biomarkers, and providing novel targets for pharmacological interventions.

Abstract
OBJECTIVE Fetuin-A is a glycoprotein produced by hepatocytes and has been associated with insulin resistance and bone growth in postnatal life. Gestational diabetes mellitus (GDM) is a condition characterized by insulin resistance. It is unclear whether GDM may affect cord blood fetuin-A levels and whether fetuin-A is associated with fetal growth. RESEARCH DESIGN AND METHODS In a nested case-control study of 153 matched pairs of neonates of mothers with GDM and euglycemic pregnancies in the Shanghai Birth Cohort, we evaluated cord blood fetuin-A in association with GDM and fetal growth. RESULTS Comparing the newborns of GDM versus euglycemic mothers, cord blood fetuin-A concentrations were similar (mean±SD: 783.6±320.0 vs 754.8±281.9 µg/mL, p=0.53), while insulin-like growth factor (IGF)-I (76.6±27.8 ng/mL vs 68.1±25.1 ng/mL, p=0.008) and IGF-II (195.3±32.5 ng/mL vs 187.5±30.8 ng/mL, p=0.042) concentrations were higher. Cord blood fetuin-A was not correlated with insulin, IGF-I or IGF-II. Cord blood fetuin-A was negatively correlated with birth weight (r=-0.19, p=0.025) and birth length (r=-0.24, p=0.005) z scores in GDM pregnancies, while there were no significant correlations in euglycemic pregnancies (tests for interaction: p=0.014 for birth length, p=0.013 for birth length). Adjusting for maternal and neonatal characteristics, the differential associations remained. CONCLUSIONS GDM was not associated with cord blood fetuin-A levels. Fetuin-A was negatively associated with fetal growth in GDM but not in euglycemic pregnancies. This novel observation suggests a GDM-conditional negative correlation of fetuin-A with fetal growth.

Abstract
OBJECTIVE To examine the effects of dynamic change in fetuin-A levels before the diagnosis of gestational diabetes mellitus (GDM) on insulin resistance and GDM. RESEARCH DESIGN AND METHODS A total of 135 women with GDM and 135 normal glucose tolerance (NGT) women with matched age (±2 years old) and gestational age at taking the oral glucose tolerance test (OGTT) were included in this nested case-control study. Fasting venous blood samples were collected at the prenatal visit of the first trimester and during OGTT of the second trimester. Plasma concentration of fetuin-A and insulin was determined. RESULTS The plasma fetuin-A concentration in women with GDM was significantly higher than NGT controls in both the first trimester (medians: 403.0 pg/mL vs 273.4 pg/mL; p<0.05) and the second trimester (medians: 475.7 pg/mL vs 290.8 pg/mL; p<0.05) and notably increased from the first to the second trimester. Multivariate linear regression analysis showed that the change in fetuin-A concentration was associated with the changes in fasting insulin, homeostasis model assessment (HOMA) of insulin resistance, and HOMA of β-cell function (HOMA-β) (p<0.05). The highest quartile of the increase in fetuin-A concentration from the first to the second trimester was associated with a higher risk of developing GDM compared with the lowest quartile (OR 2.14; 95% CI 1.05 to 4.37). CONCLUSIONS The dynamic change in fetuin-A levels was associated with the changes in insulin resistance and β-cell function from the first to the second trimester, and was associated with an increased risk of the development of GDM, indicating that fetuin-A could be a biomarker to predict the risk of GDM.

Abstract
Vascular aging in obesity and type 2 diabetes (T2D) is associated with progressive vascular calcification, an independent predictor of morbidity and mortality. Pathways for vascular calcification modulate bone matrix deposition, thus regulating calcium deposits. We investigated the association between biomarkers of vascular calcification and vasodilator function in obesity or T2D, and whether antidiabetic therapies favorably impact those markers. Circulating levels of proteins involved in vascular calcification, such as osteopontin (OPN), osteoprotegerin (OPG), regulated on activation, normal T cell expressed and secreted (RANTES), and fetuin-A were measured in lean subjects, individuals with metabolically healthy obesity (MHO), and patients with metabolically unhealthy obesity (MUO) or T2D. Vasodilator function was assessed by infusion of ACh and sodium nitroprusside (SNP). Circulating levels of OPN were higher in the MUO/T2D group than in lean subjects (P < 0.05); OPG and RANTES were higher in MUO/T2D group than in the other groups (both P < 0.001); fetuin-A was not different between groups (P > 0.05); vasodilator responses to either ACh or SNP were impaired in both MUO/T2D and MHO compared with lean subjects (all P < 0.001). In patients with T2D who were enrolled in the intervention trial, antidiabetic treatment with glyburide, metformin, or pioglitazone resulted in a significant reduction of circulating OPG (P = 0.001), without changes in the other biomarkers and vasodilator responses (all P > 0.05). In conclusion, obese patients with MUO/T2D have elevated circulating OPN, OPG, and RANTES; in these patients, antidiabetic treatment reduces only circulating OPG. Further study is needed to better understand the mechanisms of vascular calcifications in obesity and diabetes.

Abstract
BACKGROUND Diagnosis is the most strenuous step in the evaluation of neonatal sepsis. No gold standard diagnostic method is available except for blood culture. We aimed to investigate the role of positive and negative acute phase reactants, namely presepsin and fetuin-A, in the diagnosis of culture-proven late-onset sepsis. METHODS A prospective, case-control study with the infants ≤32 weeks of age with a diagnosis of culture-proven late-onset sepsis was designed. Twenty-nine preterm infants with similar gestational and postnatal ages without sepsis constituted the control group. Serum values of presepsin, fetuin-A, C-reactive protein and interleukin-6 were evaluated at the enrollment, third and seventh days of the diagnosis in the infants with positive blood culture results. RESULTS First-day presepsin values were significantly higher in the culture-positive infants than the control group [1583 ng/L (1023-1731) vs. 426 ng/L (287-589), p = < 0.0001]. Presepsin was found to have an 88.9% sensitivity and 88.9% specificity with a cut-off value of 823 ng/ml for culture-proven LOS in our study, and area under the receiver-operating curve was 0.939. Fetuin-A levels were similar between the study and control groups (p > 0.05). CONCLUSION Presepsin may be an accurate marker for both diagnosis and monitoring of treatment response for culture-proven late-onset sepsis in preterm infants. However, fetuin-A does not seem to be a useful tool for the diagnosis of sepsis.

Abstract
BACKGROUND Fetuin-A is a hepatokine that involved in the pathogenesis of insulin resistance. Previous epidemiological studies have found a positive association between blood fetuin-A and type 2 diabetes mellitus (T2DM) risk among Caucasians and African Americans. We aimed to investigate the prospective relationship between fetuin-A and T2DM in an Asian population for the first time. METHODS A nested case-control study was established within a prospective cohort of Chinese living in Singapore. At blood collection (1999 to 2004), all participants were free of diagnosed T2DM and aged 50 to 79 years. At subsequent follow-up (2006 to 2010), 558 people reported to have T2DM and were classified as incident cases, and 558 controls were randomly chosen from the participants who did not develop T2DM to match with cases on age, sex, dialect group, and date of blood collection. Plasma fetuin-A levels were measured retrospectively in cases and controls using samples collected at baseline. Conditional logistic regression models were used to compute the odds ratio (OR) and 95% confidence interval (CI). Restricted cubic spline analysis was used to examine a potential non-linear association between fetuin-A levels and T2DM risk. RESULTS Compared with those in the lowest fetuin-A quintile, participants in the highest quintile had a two-fold increased risk of developing T2DM (OR, 2.06; 95% CI, 1.21 to 3.51). A non-linear association was observed (P nonlinearity=0.005), where the association between fetuin-A levels and T2DM risk plateaued at plasma concentrations around 830 μg/mL. CONCLUSION There is a positive association between plasma fetuin-A levels and risk of developing T2DM in this Chinese population.

Abstract
OBJECTIVE We investigated the utility of maternal fetuin-A, N-terminal proatrial natriuretic peptide (pro-ANP), high-sensitivity C-reactive protein (hs-CRP), and fasting glucose levels at 11-14 gestation weeks for predicting pregnancies complicated by gestational diabetes mellitus (GDM). SUBJECTS AND METHODS This prospective cohort study included 327 low-risk pregnant women who completed antenatal follow-up at a tertiary research hospital between January and April 2014. Maternal blood samples were collected between 11-14 gestational weeks in the first trimester of pregnancy and then stored at -80 °C until further analyses. During follow-up, 29 (8.8%) women developed GDM. The study population was compared 1:2 with age- and body mass index-matched pregnant women who did not develop GDM (n = 59). Fasting plasma glucose (FPG) levels and serum fetuin-A, pro-ANP, and hs-CRP levels were measured using automated immunoassay systems. RESULTS There was a significant negative correlation between fetuin-A and hs-CRP (CC = -0.21, p = 0.047) and a positive correlation between FPG and hs-CRP (CC = 0.251, p = 0.018). The areas under the receiver operating characteristic curve for diagnosing GDM were 0.337 (p = 0.013), 0.702 (p = 0.002), and 0.738 (p < 0.001) for fetuin-A, hs-CRP, and FPG, respectively. The optimal cut-off values were > 4.65, < 166, and > 88.5 mg/dL for maternal hs-CRP, fetuin-A, and FPG, respectively. CONCLUSION Reduced fetuin-A, elevated hs-CRP, and FPG levels in women in the first trimester can be used for the early detection of GDM. Further research is needed before accepting these biomarkers as valid screening tests for GDM.

Abstract
Background/aim Fetuin-A, a circulating inhibitor of calcification, is a marker of inflammatory-nutritional state. We evaluated the association between serum fetuin-A levels and vascular calcification, intima-media thickness, and nutritional and inflammatory markers in different stages of chronic kidney disease (CKD). Materials and methods CKD patients were sampled for calcium-phosphate parameters and nutritional and inflammatory markers [highly sensitive C-reactive protein (hs-CRP)], and serum fetuin-A levels. Intima-media thicknesses of the common carotid arteries (CIMT) were measured. Peripheral artery calcification scores were obtained. Results A total of 238 patients were included in the study. Fetuin-A levels in patients with end-stage renal disease were significantly lower than those in patients with stage-3 and stage-4 CKD (stage-5 vs. stage-4, P < 0.001; stage-5 vs. stage-3, P < 0.001). Fetuin-A was negatively correlated with creatinine (P < 0.001), Ca × P product (P < 0.001), hs-CRP (P = 0.01), vascular calcification score (P < 0.001), and CIMT (P < 0.001), and positively correlated with BMI (P < 0.001, r = 0.30) and serum albumin (P < 0.001). Conclusion Lower levels of fetuin-A were associated with higher vascular calcification scores, CIMT, hs-CRP levels, and lower BMI and albumin. Fetuin-A deficiency may be a key element for MIAC syndrome.

Abstract
BACKGROUND/AIMS We aimed to investigate the effect of a moderately high vitamin D dose on lipid parameters and biochemical markers of vascular calcification (VC) in patients with established cardiovascular disease. METHODS We included in this pre-specified secondary analysis of a randomized controlled trial 161 patients with advanced heart failure and 25-hydroxyvitamin D (25OHD) concentrations < 75 nmol/L (vitamin D group: n = 80; placebo group: n = 81), who received a daily vitamin D3 supplement of 4,000 IU for 3 years. We assessed between-group differences of the lipid parameters total-cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, and triglycerides, and the VC markers fetuin-A and non-phosphorylated undercarboxylated matrix gla protein (MGP) at study termination, with adjustment for baseline values. RESULTS Lipid parameters, the percentage of patients with dyslipoproteinemia, and VC markers did not differ significantly between groups at study termination (p values: 0.395-0.939). Likewise, vitamin D achieved no significant treatment effect on these markers in subgroup analyses in patients with 25OHD concentrations < 30 nmol/L, nonusers of lipid-lowering drugs, or diabetic patients (p values: 0.245-0.998). CONCLUSION Our data indicate that vitamin D does not improve the lipid profile and does not influence the calcification inhibitors fetuin-A and non-phosphorylated undercarboxylated MGP in patients with advanced heart failure.

Abstract
Fetuin-A is a protein with various biological functions. It plays a role in insulin resistance and arterial calcium deposition. Thyroid dysfunction may affect energy expenditure, glucose metabolism, and the risk of cardiovascular diseases. In the present study, we compared the serum fetuin-A concentrations in hyperthyroid patients with those in euthyroid patients.We recruited 30 newly-diagnosed hyperthyroid patients (the HY group) and treated them with anti-thyroid regimens as clinically indicated. We recruited 30 euthyroid individuals (the EU group) as controls. We compared laboratory parameters at the baseline and at 6 months. We then determined the associations between the levels of fetuin-A and free thyroxine (fT4), thyroid-stimulating hormone (TSH), or log transformation of TSH (logTSH).At the baseline, the HY patients had significantly higher serum fetuin-A levels than the EU patients (median [Q1, Q3]: 735.4 [537.9, 843.4] ng/mL vs 561.1[449.2, 670.5] ng/mL, P = .010). At 6 months, the serum fetuin-A levels of the HY patients decreased but were still higher than those of the EU patients (698.4 [627.6, 924.3] ng/mL vs 616.5 [498.2, 727.7] ng/mL, P = .002). At baseline, the serum levels of fetuin-A were negatively associated with logTSH (β = -53.79, P = .010). At 6 months, the levels of fetuin-A were positively associated with fT4 (β = 86.91, P = .039), and negatively associated with logTSH (β = -104.28, P < .001). Changes to the levels of fetuin-A within 6 months were negatively associated with changes to logTSH (β = -57.80, P = .019). The negative associations between fetuin-A levels and logTSH at baseline and at 6 months, and the changes during the 6 months remained significant after adjustment for sex and age (β = -51.72, P = .016; β = -103.11, P < .001; and β = -59.36, P = .020, respectively).The patients with hyperthyroidism had higher serum fetuin-A levels than the patients with euthyroidism. In patients with hyperthyroidism, the serum fetuin-A concentrations decreased after the anti-thyroid treatment. In the present study, serum fetuin-A concentrations were negatively associated with logTSH.

Abstract
BACKGROUND "T50," shortened transformation time from primary to secondary calciprotein particles may reflect deranged mineral metabolism predisposing to vascular calcification and cardiovascular disease (CVD). The glycoprotein fetuin-A is a major T50 determinant. METHODS The Folic Acid For Vascular Outcome Prevention In Transplantation (FAVORIT) cohort is a completed, large, multiethnic controlled clinical trial cohort of chronic, stable kidney transplant recipients (KTRs). We conducted a longitudinal case-cohort analysis using a randomly selected subcohort of patients, and all individual cases who developed CVD. Serum T50 and fetuin-A were determined in this total of n = 685 FAVORIT trial participants at randomization. RESULTS During a median surveillance of 2.18-years, 311 incident or recurrent CVD events occurred. Shorter T50 (minutes) or reduced fetuin-A concentrations (g/L) were associated with CVD after adjustment for treatment assignment, systolic blood pressure, age, sex, race, preexisting CVD and diabetes, smoking, body mass index, total cholesterol/HDL cholesterol, kidney allograft vintage and type, calcineurin inhibitor, or lipid-lowering drug use, estimated glomerular filtration rate, and urinary albumin/creatinine: tertile 1 (lowest) to tertile 3 (highest) comparisons, T50, (hazard ratio [HR] 1.86; 95% CI 1.20-2.89); fetuin-A, (HR 2.25; 95% CI 1.38-3.69). Elevated high sensitivity c-reactive protein (hsCRP) was an effect modifier of both these associations. CONCLUSIONS Shortened T50, as well as reduced fetuin-A levels, ostensible promoters of vascular calcification, remained associated with greater risk for CVD outcomes, after adjustment for major CVD risk factors, measures of kidney function and damage, and KTR clinical characteristics and demographics, in a large, multiethnic cohort of long-term KTRs. Increased hsCRP was an effect modifier of these CVD risk associations.

Abstract
Fetuin-A, a hepatic-origin protein, is strongly positively associated with risk of type 2 diabetes in human observational studies, but it is unknown whether this association is causal. We aimed to study the potential causal relation of circulating fetuin-A to risk of type 2 diabetes in a Mendelian randomization study with single nucleotide polymorphisms located in the fetuin-A-encoding AHSG gene. We used data from eight European countries of the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study including 10,020 incident cases. Plasma fetuin-A concentration was measured in a subset of 965 subcohort participants and 654 case subjects. A genetic score of the AHSG single nucleotide polymorphisms was strongly associated with fetuin-A (28% explained variation). Using the genetic score as instrumental variable of fetuin-A, we observed no significant association of a 50 µg/mL higher fetuin-A concentration with diabetes risk (hazard ratio 1.02 [95% CI 0.97, 1.07]). Combining our results with those from the DIAbetes Genetics Replication And Meta-analysis (DIAGRAM) consortium (12,171 case subjects) also did not suggest a clear significant relation of fetuin-A with diabetes risk. In conclusion, although there is mechanistic evidence for an effect of fetuin-A on insulin sensitivity and secretion, this study does not support a strong, relevant relationship between circulating fetuin-A and diabetes risk in the general population.

Abstract
BACKGROUND Due to the surrounding bone, the human inner ear is relatively inaccessible and difficult to reach for cellular and molecular analyses. However, these types of investigations are needed to better understand the etiology, pathophysiology and progression of several inner ear disorders. Moreover, the fluid from the inner ear cannot be sampled for micro-chemical analyses from healthy individuals in vivo. Therefore, in the present paper, we studied patients with vestibular schwannoma (VS) undergoing trans-labyrinthine surgery (TLS). Our primary aim was to identify perilymph proteins in patients with VS on an individual level. Our second aim was to investigate the proteins identified at a functional level and our final aim was to search for biological markers for tumor-associated hearing loss and tumor diameter. METHODS AND FINDINGS Sixteen patients underwent TLS for sporadic VS. Perilymph was aspirated through the round window before opening the labyrinth. One sample was contaminated and excluded resulting in 15 usable samples. Perilymph samples were analyzed with an online tandem LTQ-Orbitrap mass spectrometer. Data were analyzed with MaxQuant software to identify the total number of proteins and to quantify proteins in individual samples. Protein function was analyzed using the PANTHER Overrepresentation tool. Associations between perilymph protein content, clinical parameters, tumor-associated hearing loss and tumor diameter were assessed using Random Forest and Boruta. In total, 314 proteins were identified; 60 in all 15 patients and 130 proteins only once in 15 patients. Ninety-one proteins were detected in at least 12 out of 15 patients. Random Forest followed by Boruta analysis confirmed that alpha-2-HS-glycoprotein (P02765) was an independent variable for tumor-associated hearing loss. In addition, functional analysis showed that numerous processes were significantly increased in the perilymph. The top three enriched biological processes were: 1) secondary metabolic processes; 2) complement activation and 3) cell recognition. CONCLUSIONS The proteome of perilymph in patients with vestibular schwannoma has an inter-individual stable section. However, even in a cohort with homogenous disease, the variation between individuals represented the majority of the detected proteins. Alpha-2-HS-glycoprotein, P02765, was shown to be an independent variable for tumor-associated hearing loss, a finding that needs to be verified in other studies. In pathway analysis perilymph had highly enriched functions, particularly in terms of increased immune and metabolic processes.

Abstract
The liver is a central regulator of whole body glucose, and lipid homeostasis and hepatokines, like fetuin-A, have been identified as markers and mediators of fatty liver-induced cardiometabolic risk. The closely related protein fetuin-B was shown to be upregulated in the fatty liver and to impact on glucose homeostasis in mice. In the present study we aimed to test the relevance of these findings in humans. In 55 subjects, hepatic mRNA expression of both hepatokines, fetuin-A and fetuin-B, associated positively with liver triglyceride content, whereas only fetuin-A expression associated with the homeostatic model assessment of insulin resistance. In 220 subjects who underwent precise metabolic phenotyping, circulating fetuin-A, but not fetuin-B, associated positively with liver fat content, and negatively with insulin sensitivity, measured during the oral glucose tolerance test (OGTT) and during the euglycemic, hyperinsulinemic clamp. Both circulating fetuin-A and fetuin-B correlated positively with the glucose area under the curve during the OGTT, but after additional adjustment for insulin sensitivity this relationship remained significant only for fetuin-B. In conclusion, despite the fact that the two hepatokines, fetuin-A and fetuin-B, are upregulated in the state of hepatic steatosis in humans, it appears that they differently impact on glucose homeostasis. Our data are in agreement with observations that fetuin-A can alter insulin signaling and that fetuin-B may regulate glucose homeostasis via so far unknown effects, possibly on glucose effectiveness.

Abstract
Chemerin and fetuin-A are recently discovered as metabolic regulator hormone in obesity and type 2 diabetes mellitus. However, elevated levels of chemerin and fetuin-A have been associated with insulin resistance and systemic inflammation. The present study aimed to investigate the significance of serum chemerin and fetuin-A levels in obese diabetic patients. Also, to determine whether, chemerin and fetuin-A along with markers of inflammation (IL6 and CRP) and obesity-related parameters in T2DM patients. Serum levels of chemerin and fetuin-A were evaluated using ELISA in 71 T2DM patients and 14 apparently healthy controls. Both groups were subdivided into obese and lean. Serum chemerin and fetuin-A levels were significantly higher in T2DM patients compared to controls (P < 0.001, for both) and significantly higher in obese T2DM in comparison to obese control group (P < 0.01 & P < 0.05, respectively). Serum chemerin and fetuin-A levels correlated positively with HbA1c, HOMA-IR, FBG, IL6 and CRP. In obese patients, serum chemerin and fetuin-A levels correlated positively with BMI and waist circumference. In conclusion, the strong association of chemerin and fetuin-A with insulin resistance and some inflammatory markers may provide an interesting link between obesity, inflammation and diabetes mellitus in human.

Abstract
BACKGROUND AND AIMS Fetuin-A has been proposed as a marker of liver damage in adults with obesity-related NAFLD. The aim of this study was to test serum fetuin-A concentrations in obese children with NAFLD diagnosed either by ultrasonography or by liver biopsy and to determine its applicability as predictive tool in pediatric NAFLD. METHODS AND RESULTS Metabolic parameters and fetuin-A levels were investigated in 81 obese children with NAFLD diagnosed by biopsy, 79 obese children with NAFLD defined by liver ultrasonography and 23 lean subjects. Serum fetuin-A correlated significantly with age, waist circumference, systolic blood pressure, fasting insulin and 2-h postload insulin during OGTT, HOMA-IR, ISI, CRP, and apo B levels. Obese children with NAFLD detected by ultrasonography had significantly higher fetuin-A levels compared to those with normal liver. In obese children who underwent liver biopsy, no significant differences were detected in fetuin-A levels between subject with nonalcoholic steatohepatitis and those with simple steatosis. Fetuin-A was not different between obese and lean children. CONCLUSION Fetuin-A is not related with the degree of liver damage in obese children with NAFLD and its routine measurement as marker of liver disease severity is therefore not recommended.

Abstract
AIMS Fetuin-A has been linked to insulin resistance and obesity. Its role in the pathogenesis of type 2 diabetes (T2DM) has also been discussed. We aimed to investigate the prospective association of fetuin-A and the risk of T2DM in a systematic review and meta-analysis. METHODS A systematic search of studies from the MEDLINE, EMBASE, Pubmed and Web of Science using fetuin-A, diabetes and various synonyms was conducted up to June 5, 2017. Relevant studies were extracted by two reviewers independently. The quality of studies was assessed using Newcastle-Ottawa scales. Overall estimates were pooled using fixed effect with inverse variance meta-analysis. Subgroup analyses by gender, study population, techniques of assessing fetuin-A, diabetes ascertainment methods, follow-up duration and measures of association were conducted. RESULTS Seven studies comprising a total of 11,497 individuals and 2176 cases of T2DM were included in the systematic review and meta-analysis. Overall, one SD increment of fetuin-A level was associated with a 23% greater risk of incident T2DM (RR: 1.23, 95% CI 1.16-1.31). No significant heterogeneity or publication bias was found. The association was relatively stable across different subgroups. However, the association seemed only evident in women, but not in men. CONCLUSIONS Higher circulating fetuin-A levels were associated with increased risk of T2DM. However, the causality deserved further analysis.

Abstract
INTRODUCTION Hyperbaric oxygen (HBO₂) treatment results in elevated production of reactive oxygen species (ROS) that leads to cellular damage. Thymoquinone (TQ) is reported to have anti-inflammatory and antimicrobial activity and may suppress the generation of free radicals. The goal of this study is reduction of side effects of hyperbaric oxygen therapy with thymoquinone treatment. METHODS 30 female Sprague-Dawley rats were randomly assigned to one of three groups (n = 10 per group). Group 1 represented the control group (no treatment). Group 2 was exposed to 100% oxygen at 2.5 ATA for two sessions of two hours'duration each day for five days. Group 3 was treated identically to Group 2 and was also given thymoquinone once daily at 50 mg/kg/day by oral gavage for five days, after first session of HBO₂. RESULTS LOOH and SH levels were significantly elevated in the group receiving HBO₂ treatment relative to the control group rats. Fetuin A is increased during TQ treatment. LOOH and SH levels were significantly decreased in animals treated with TQ. CONCLUSIONS Long-term and repeated HBO₂ treatment leads to damage to the lung tissue. In urgent situations or cases of severe hypoxia, repeated HBO₂ sessions may be necessary, and TQ antioxidant agents may be useful for prevention of HBO₂-associated injury. TQ may represent a useful therapeutic option during HBO₂ treatment.

Abstract
AIMS Fetuin-A is a hepatic glycoprotein that is involved in insulin resistance and atherosclerosis. Herein we examined the association of plasma fetuin-A levels with peripheral arterial disease (PAD) in patients with type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS A total of 71 patients with T2DM and 57 non-diabetic individuals were recruited. Diagnosis of PAD was based on the absence of triphasic waveform at pedal arteries, while ankle-brachial index (ABI) was calculated. Radiographs of both feet and ankles were taken for the assessment of lower extremity arterial calcification (LEAC). Plasma fetuin-A levels were measured using ELISA. RESULTS Patients with T2DM had higher fetuin-A levels than non-diabetic participants. Participants with diabetes and PAD had lower fetuin-A levels than non-PAD diabetic patients. In subjects with T2DM fetuin-A levels were associated with ABI. Multivariate analysis demonstrated that in patients with T2DM the odds of PAD increased with long diabetes duration, smoking, presence of arterial hypertension and dyslipidemia, as well as with lower fetuin-A levels. A trend towards higher fetuin-A levels in subjects with less severe LEAC was found. CONCLUSION Plasma fetuin-A levels are lower in patients with T2DM and PAD and are associated with PAD, irrespective of traditional cardiovascular risk factors. Moreover, fetuin-A may be involved in arterial calcification.

Abstract
AIM To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein (AHSG/fetuin A) and potential associations with disease and patient characteristics. METHODS AHSG serum levels were determined in treatment-naïve newly-diagnosed patients, 96 with ulcerative colitis (UC), 84 with Crohn's disease (CD), 62 with diarrhea-predominant or mixed irritable bowel syndrome (IBS, D- and M- types) and 180 healthy controls (HC), by an enzyme linked immunosorbent assay (ELISA). All patients were followed for a minimum period of 3 years at the Gastroenterology Department of the University Hospital of Larissa, Greece. C-reactive protein (CRP), anti-glycan antibodies, anti-Saccharomyces cerevisiae mannan antibodies IgG, anti-mannobioside carbohydrate antibodies IgG, anti-laminariobioside carbohydrate antibodies IgG and anti-chitobioside carbohydrate antibodies IgA were also determined via immunonephelometry and ELISA, respectively. RESULTS The mean ± SE of serum AHSG, following adjustment for confounders, was 0.32 ± 0.02 g/L in IBD, 0.32 ± 0.03 g/L in CD and 0.34 ± 0.03 g/L in UC patients, significantly lower than in IBS patients (0.7 ± 0.018 g/L) and HC (0.71 ± 0.02 g/L) (P < 0.0001, in all cases). AHSG levels were comparable between the CD and UC groups. Based on AHSG levels IBD patients could be distinguished from HC with about 90% sensitivity and specificity. Further adjusted analysis verified the inverse association between AHSG and penetrating, as well as stricturing CD (partial correlation coefficient: -0.45 and -0.33, respectively) (P < 0.05). After adjusting for confounding factors, inverse correlations between AHSG and CRP and the need for anti-TNFα therapy or surgery, were found (partial correlation coefficients: -0.31, -0.33, -0.41, respectively, P < 0.05, in all cases). Finally, IBD individuals who were seropositive, for at least one marker, had AHSG levels falling within the two lower quartiles (OR = 2.86, 95%CI: 1.5-5.44, P < 0.001) while those with at least two serological markers positive exhibited AHSG concentrations within the lowest quartile (OR = 5.03, 95%CI: 2.07-12.21, P < 0.001), after adjusting for age, sex and smoking. CONCLUSION AHSG can be used to distinguish between IBD and IBS patients or HC while at the same time "predicting" complicated disease behavior, need for therapy escalation and surgery. Moreover, AHSG may offer new insights into the pathogenesis of IBD, since it is involved in key processes.

Abstract
Fetuin-A is a hepatic secretory protein and a novel risk factor for diabetes. However, it remains unclear whether the association between high levels of fetuin-A and diabetes can be attributed to nonalcoholic fatty liver disease. We conducted a case-cohort study among 1,957 subcohort members and 455 incident diabetes cases in the Multi-Ethnic Study of Atherosclerosis, a multicenter US study of Caucasian, African-American, Hispanic, and Chinese-American adults aged 45-84 years. Serum fetuin-A and computed tomography-determined liver fat content were measured from samples collected at baseline (2000-2002). In multivariable Cox proportional hazards models with follow-up through 2012, a higher fetuin-A level was associated with a higher risk of diabetes, with a stronger association among women (for top quartile vs. bottom, hazard ratio (HR) = 3.36, 95% confidence interval (CI): 2.08, 5.44) than among men (HR = 1.47, 95% CI: 0.93, 2.35) (P-heterogeneity = 0.001). Adjustment for liver fat content attenuated these associations slightly (women: HR = 2.61, 95% CI: 1.59, 4.26; men: HR = 1.32, 95% CI: 0.84, 2.08). In this study, we observed a particularly strong association of fetuin-A with diabetes risk in women that could not be explained by liver fat.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a chronic and multifactorial syndrome characterized by a low-grade chronic inflammation, and a major risk factor for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). In our study, we aimed to investigate the serum levels of high sensitive C-reactive protein (hs-CRP), haptoglobin (Hp), α2-macroglobulin (α2-MG), platelet factor-4 (PF-4), fetuin-A, serum amyloid P (SAP) and α1-acid glycoprotein (AGP) in an adolescent population with MetS. METHODS This study was performed in 43 (18 males, 25 females) MetS adolescents between the ages of 13 and 17 years (14.70±1.15) and 43 lean controls were matched for age and sex. The serum levels of Hp, α2-MG, PF-4, fetuin-A, SAP and AGP were measured by using a multi-ELISA technique. RESULTS Serum Hp, fetuin-A (p<0.01) and PF-4, hs-CRP, SAP, AGP (p<0.001) values of the MetS subjects were significantly higher than those of the controls. No difference was found in serum α2-MG levels between the MetS and control groups (p=0.184). CONCLUSIONS This finding suggests the possibility of using these markers in diagnosis of MetS in adolescents to prevent future complications.

Abstract
BACKGROUND Some changes of glycoproteins have been identified in the serum of patients with different liver diseases, which provided potential glycan biomarkers for diagnosis, prognosis and monitoring of disease progression. METHODS We established a lectin-antibody sandwich ELISA method to detect fucosylated fetuin A (fuc-fetuin A) level in serum, in which biotinylated Aleuria aurantia lectin (AAL) was used for specific recognition. Then serum fuc-fetuin A level was detected in 108 healthy controls and 548 hepatitis B virus (HBV)-infected patients, including 232 hepatocellular carcinoma (HCC) patients, 114 liver cirrhosis (LC) patients, 86 liver fibrosis (LF) patients, and 116 asymptomatic HBV carriers, to assess its diagnostic and prognostic value in HBV-related liver diseases. RESULTS Serum fetuin A level decreased in LC patients as compared to HCC patients or healthy controls, while it decreased further according to the increasing Child-Pugh grades. The fuc-fetuin A level was in a decreasing order in LC, HCC, LF, HBV-carriers and healthy controls. For distinguishing LC and HCC patients from LF, HBV-carriers and healthy controls, the area under the receiver operating characteristic (ROC) curve is 0.871, with a sensitivity of 0.818 and specificity of 0.819. The survival analysis revealed that higher fuc-fetuin A level was significantly associated with worse recurrence-free survival in HCC patients (p=0.018). CONCLUSIONS The results indicated that the serum fuc-fetuin A might serve as a potential glycan biomarker for distinguishing LC and HCC from LF, HBV-carriers and healthy controls. Furthermore, the preoperative fuc-fetuin A level could be a useful prognostic biomarker for HCC patients.

Abstract
BACKGROUND Insulin resistance (IR) and type 2 diabetes mellitus (T2DM) are serious extrahepatic manifestations of chronic hepatitis C virus (HCV) infection. However, the mechanism underlying the IR in chronic HCV is obscure. Hepatokines are group of liver-derived protein, which affect the glucose and lipid metabolism in several tissues. Fetuin A (also known as human α2-HS-glycoprotein) is one of the hepatokines, which was recognized as a natural inhibitor of the insulin receptor tyrosine kinase in liver and skeletal muscle. Additionally, selenoprotein P has emerged as an important hepatokine, which primarily acts as selenium transporter and has been reported to be implicated in glucose homeostasis in human. OBJECTIVE The aim of the current case-control study was to investigate the serum levels of both fetuin A and selenoprotein P in chronic hepatitis C patients with or without T2DM and to correlate their levels with other biochemical parameters of insulin resistance. MAIN FINDINGS Our results showed that, serum fetuin A levels increased significantly in HCV patients compared with controls (P<0.01) and surplus increase was found in HCV with concomitant T2DM (P>0.001). However, selenoprotein P levels significantly elevated only in patients with both HCV and T2DM (P<0.05) compared with the healthy subjects. Both fetuin A and selenoprotein P were positively correlated with fasting blood glucose. Yet, only fetuin A was significantly correlated to the HOMA-IR (r=0.28; P=0.03). CONCLUSIONS These results indicate crucial roles played by fetuin A and selenoprotein P in the IR caused by HCV and that both hepatokines may be targets for the development of therapies to treat or inhibit insulin resistance associated to HCV. However, further studies on large scale should be conducted to confirm our findings.

Abstract
BACKGROUND Recent studies showed that fetuin-A and matrix metalloproteinase-7 (MMP-7) are type 2 diabetes mellitus (T2DM)-associated markers. Bariatric surgery not only reduces body weight but also improves T2DM. This study aimed to investigate the changes of fetuin-A and MMP-7 in obese subjects with and without T2DM after bariatric surgery. METHODS We enrolled 130 obese subjects that received bariatric surgery, including 41 Roux-en-Y gastric bypass (RYGB), 67 mini-gastric bypass (MGB), and 22 sleeve gastrectomy (SG) patients. Forty-three patients suffered from T2DM prior to surgery. The fasting serum fetuin-A and MMP-7 levels were measured before and 1 year after surgery. RESULTS Only five of 43 patients remained diabetic after surgery. Preoperative T2DM patients had higher fetuin-A and MMP-7 levels than non-T2DM subjects. RYGB, MGB, and SG all decreased the fetuin-A levels 1 year after the operation. The MMP-7 levels were not changed after RYGB, MGB, or SG. In multivariate analyses, the preoperative fetuin-A was significantly related to the diastolic blood pressure (DBP) and glycosylated hemoglobin (HbA1c), while the postoperative fetuin-A was independently related to the waist-to-hip ratio and HbA1c. Moreover, the preoperative MMP-7 level was significantly related to age, DBP, aspartate transaminase, alanine transaminase, and gamma-glutamyl transferase (rGT), while the postoperative MMP-7 level was independently related to age and rGT. CONCLUSIONS The fetuin-A and MMP-7 levels are both higher in obese T2DM than non-T2DM subjects. The level of fetuin-A is reduced after RYGB, MGB, and SG, but the level of MMP-7 remains unchanged.

Abstract
BACKGROUND Fetuin A is an inhibitor of insulin action and have been found to be related with subcutaneous lipid accumulation and insulin resistance. The relation of cardiac lipid accumulation, fetuin A and insulin resistance parameters in obese children is not well-known. The aim of the study was to evaluate the relation of serum fetuin A levels with subcutaneous and cardiac lipid accumulation, and insulin resistance parameters in Turkish obese children. METHODS Serum fetuin A levels, cardiac and subcutaneous lipid accumulation parameters of 42 obese (10.9±2.3 years, 19 female) and 40 control group subjects (11.2±2.7) were compared. Cardiac lipid accumulation measured by subepicardial adipose tissue thickness. Insulin resistance was assessed using homeostasis model assessment (HOMA-IR) index. RESULTS There were significant correlations serum fetuin A levels with BMI-SDS, circumferences of waist, hip and midarm, SATT and HOMA-IR (r=0.362, p=0.018, r=0.728, p=0.001, r=0.662, p=0.0001, r=0.713, p=0.0001, r=0.477, p=0.001, and r=0.330, p=0.038 as, respectively). CONCLUSIONS Fetuin A was correlated well with cardiac and subcutaneous lipid accumulation, insulin resistance parameters, which may be related with early pathogenetic mechanisms of metabolic obesity complications in children.

Abstract
OBJECTIVES To analyze inflammatory markers, adipokines, and hepatokines in obese adolescents with and without type 2 diabetes mellitus (T2DM). STUDY DESIGN We studied high sensitivity C-reactive protein (hsCRP), tumor necrosis factor (TNF)-α, interleukin-1β, and interferon-γ, the hepatokines (fetuin-A and fibroblast growth factor [FGF]-21), and the adipokines (adiponectin and leptin) in a cross-sectional study of 74 predominately Caucasian adolescents with T2DM aged 12-18 years and in 74 body mass index (BMI)-, age-, and sex-matched controls. RESULTS Adolescents with T2DM had significantly higher concentrations of hsCRP, TNF-α, and interleukin-1β compared with obese controls without T2DM. Interferon-γ was not detectable in obese adolescents with or without T2DM. In multiple linear regression analysis, hsCRP was significantly associated with FGF-21 and BMI, but not with hemoglobin A1c, adiponectin, leptin, fetuin-A, sex, or age. TNF-α was significantly related negatively to leptin, positively to BMI, but not to hemoglobin A1c, adiponectin, fetuin-A, FGF-21 sex, or age in multiple linear regression analysis. CONCLUSIONS Increased inflammatory markers are associated with T2DM in adolescents. Because hsCRP was related to FGF-21 and TNF-α was associated with leptin, these findings suggest a link between increased levels of these adipokines and hepatokines and chronic inflammation. Future longitudinal studies in humans are necessary to confirm these hypotheses.

Abstract
Background Calciprotein particles (CPPs) may play an important role in the calcification process. The calcification propensity of serum (T50) is highly predictive of all-cause mortality in chronic kidney disease patients. Whether T50 is therapeutically improvable, by high-flux hemodialysis (HD) or hemodiafiltration (HDF), has not been studied yet. Methods We designed a cross-sectional single center study, and included stable prevalent in-center dialysis patients on HD or HDF. Patients were divided into two groups based on dialysis modality, were on a thrice-weekly schedule, had a dialysis vintage of > 3 months and vascular access providing a blood flow rate > 300 ml/min. Calcification propensity of serum was measured by the time of transformation from primary to secondary CPP (T50 test), by time-resolved nephelometry. Results We included 64 patients, mean convective volume was 21.7L (SD 3.3L). In the pooled analysis, T50 levels increased in both the HD and HDF group with pre- and post-dialysis (mean (SD)) of 244(64) - 301(57) and 253(55) - 304(61) min respectively (P = 0.43(HD vs. HDF)). The mean increase in T50 was 26.29% for HD and 21.97% for HDF patients (P = 0.61 (HD vs. HDF)). The delta values (Δ) of calcium, phosphate and serum albumin were equal in both groups. Baseline T50 was negatively correlated with phosphate, and positively correlated with serum magnesium and fetuin-A. The ΔT50 was mostly influenced by Δ phosphate (r = -0.342; P = 0.002 HD and r = -0.396; P<0.001 HDF) in both groups. Conclusions HD and HDF patients present with same baseline T50 calcification propensity values pre-dialysis. Calcification propensity is significantly improved during both HD and HDF sessions without significant differences between both modalities.

Abstract
INTRODUCTION Fetuin-A plays an important role in bone turnover and vascular calcification. AIM The aim of the study was to assess the relationship between serum fetuin-A concentrations, inflammatory and bone turnover markers of patients on maintenance hemodialysis. MATERIALS AND METHODS The study was performed in 71 patients (21 women, 40 men) aged 60 ± 12 years on chronic dialysis because of end-stage renal failure for a period of 75 ± 57.2 months. The routine laboratory tests were performed with Modular P analyzer (Roche Diagnostics), serum concentrations of iPTH were measured using Nichols method, hsCRP and IL-6 using nephelometric techniques while fetuin-A, bone-specific alkaline phosphatase (bALP), fully carboxylated osteocalcin (cOC), undercarboxylated osteocalcin (ucOC), and fibroblast growth factor-23 (FGF-23) were measured using commercially available ELISA kits. RESULTS Concentrations of fetuin-A were significantly positively correlated with albumin (r=0.37, p=0.003) and negatively associated with patients age (r=26, p=0.04), log (iPTH) (r=0.31, p=0.02), log (CRP) (r=0.31, p=0.02), log (IL-6) (r=0.41, p=0.001), log (ucOC) (r=-0.29, p=0.02), and log (FGF-23) (r=0.27, p=0.04). CONCLUSIONS 1. Patients on maintenance hemodialysis suffer from severe disturbances of bone turnover. 2. Low serum fetuin-A levels are associated with increase markers of bone turnover and inflammation.

Abstract
We present the case of a non-dialyzed patient with chronic kidney disease and biopsy-proven calciphylaxis who presented with painful cutaneous ulcers on both legs. The skin ulcers drastically improved within 6 months after the initiation of hemodialysis, aggressive wound care, the control of a mineral and bone disorder, and the administration of sodium thiosulfate and hyperbaric oxygen therapy. Notably, the patient's serum levels of C-reactive protein and calciprotein particles decreased and her serum albumin and fetuin-A levels increased in parallel with the alleviation of her calciphylaxis. This case highlights the importance of applying combined medical treatment to calciphylaxis and suggests the possible involvement of calciprotein particles in the pathogenesis of calciphylaxis.

Abstract
AIMS Fetuin-A is a circulating glycoprotein capable of inhibiting insulin signaling both in vivo and in vitro and is positively associated with insulin resistance. Osteoprotegerin (OPG) acts as a regulatory molecule with increased levels in the early stages of diabetes and atherosclerosis, and is also associated with insulin resistance. We investigated the effects of pioglitazone and metformin as representative insulin-sensitizing therapies on fetuin-A and OPG levels. MATERIALS AND METHODS In a randomized clinical trial setting (NCT02027103), 88 patients with newly diagnosed type 2 diabetes were randomly assigned to pioglitazone (30 mg/day, n=46) or metformin (1000 mg/day, n=42) for 12 weeks. Various anthropometric and metabolic parameters, fetuin-A, OPG, highly sensitive C-reactive protein (hsCRP), and homeostasis model assessment of insulin resistance (HOMA-IR) were measured at baseline and after three months. RESULTS The reduction in fasting plasma glucose and haemoglobin A1c levels was comparable in the two arms. Pioglitazone resulted in a significant reduction in both fetuin-A and OPG in men, but only fetuin-A in women. Metformin was only effective in lowering OPG levels in women. When compared, both medications were equally effective with regard to fetuin-A and OPG reduction in women (p=0.413 and 0.359, respectively). In men, pioglitazone more effectively decreased fetuin-A levels in both uni- (p=0.011) and multivariate models (p=0.015) and OPG levels in only uni- (p=0.023) but not the multivariate model (p=0.547). CONCLUSIONS Metformin and pioglitazone differentially affect fetuin-A and osteoprotegrin levels in diabetic women and men. The level of change may not necessarily be associated with the amelioration of insulin resistance.

Abstract
Vascular calcification results from an imbalance between increased extracellular levels of calcium and phosphate, reduced solubility, and low levels of calcification inhibitors in blood or the vascular wall. Fetuin-A is a major circulating calcification inhibitor. Rodent models of fetuin-A deficit indicate its calcification inhibiting potential. Clinical studies suggest its role as a biomarker in vascular disease. This cross-sectional study was performed in a cohort of 974 men aged ≥ 40 years (average 68 years) consisting of men holding health insurance cover with Mutuelle des Travailleurs de la Région Lyonnaise. Abdominal aortic calcification (AAC) was assessed semi-quantitatively on lateral dual energy X-ray absorptiometry (DXA) spine scans. Serum fetuin-A was measured by an immunoassay. After adjustment for confounders (age, lifestyle, body composition, health status, treatment, glomerular filtration rate [GFR], hormones, and cytokines), prevalence of severe AAC (AAC score>4) decreased with increasing fetuin-A levels (OR=0.68 per SD increase, 95% CI: 0.54-0.84, p<0.001). After adjustment for confounders, low fetuin-A and hypertension were each associated with higher odds of AAC>4. Coexistence of low serum fetuin-A levels and heavy smoking, elevated fibroblast growth factor 23 levels or low serum dickkopf-1 levels were associated with higher odds of AAC>4. Similar results were obtained for 789 men with GFR>60 mL/min/1.73 m(2). Similar results were obtained when severe AAC was defined as AAC score >3 or AAC>5. Thus, lower serum fetuin-A levels are associated with severe AAC, suggesting that poor calcification inhibitory potential contributes to vascular calcification, independently of renal impairment.

Abstract
AIM Fetuin-A levels are reported to be low as a negative acute phase reactant in systemical inflammatory situations. Hashimoto thyroiditis is characterized with inflammation. In this study, we hypothesised that the serum fetuin A levels could be found to be low due to inflammation in patients with Hashimoto thyroiditis. For this purpose, serum fetuin A levels in patients with Hashimoto thyroiditis were compared with those in healthy subjects. METHODS A total of 85 participants (11 male, 74 female, mean age: 38.60±10.14 years) were included. The patient group consisted of 44 Hashimoto thyroiditis patients with subclinical hypothyroidism (7 male, 37 female) and the control group consisted of 41 healthy subjects (4 male, 37 female). Groups were compared according to their demographic, anthropometric and biochemical data and serum fetuin-A levels. Correlation analysis was used for determining the relation between fetuin A levels and clinical parameters. RESULTS Fetuin-A levels of the patient group were found lower than those of the control group (0.58±0.50 g/L versus 1.53±1.60 g/L, P=0.001). Fetuin-A levels were not correlated with clinical parameters such as TSH, C-reactive protein, body mass index, waist circumference, blood pressure, glucose, and lipids. CONCLUSION These findings supported the hypothesis that serum fetuin A levels could be found to be low as a negative acute phase reactant in patients with Hashimoto thyroiditis. Fetuin A can be considered as an indicator of inflammation in Hashimoto thyroiditis.

Abstract
OBJECTIVE To evaluate fetuin-A level and carotid intima-media thickness (CIMT) in adolescent type 1 diabetics. PATIENTS AND METHODS The study included 62 type 1 diabetic patients and 30 healthy volunteers of the same age and sex. Blood sample was taken for assessment of glycosylated hemoglobin (HbA1), lipid profile, and fetuin-A. Urine sample was also taken for assessment of albumin/creatinine ratio. Anthropometric measurements were taken, including weight, height, and waist and hip circumference. CIMT was assessed for all patients and controls. RESULTS Serum fetuin-A, Rt., Lt. and both CIMT were significantly higher in diabetics. Fetuin-A had a significant positive correlation with duration of disease, waist and hip circumference, BMI, BMI SDS, waist/height ratio, Rt., Lt. and both CIMT. Stepwise multiple regression analysis revealed that the duration of disease, waist/height ratio, and HDL-c were the factors related to fetuin-A. CONCLUSION Adolescent type 1 diabetic patients have high fetuin-A levels and increased CIMT, with the latter representing the development of early atherosclerosis. In this light, adolescents with type 1 diabetes require frequent follow up for early detection of atherosclerosis.

Abstract
OBJECTIVE The objective of this trial was to determine the levels of inflammatory markers, high-sensitivity C-reactive protein and fetuin-A pre- and post-levothyroxine treatment in cases of subclinical hypothyroidism. MATERIALS AND METHODS A total of 32 patients with a diagnosis of subclinical hypothyroidism and a control group of 30 healthy individuals were tested for high-sensitivity C-reactive protein and fetuin-A, followed by the administration of 50 µg of levothyroxine in the patient group for 3 months. During the post-treatment stage, high-sensitivity C-reactive protein and fetuin-A levels in the patient group were re-assessed and compared with pre-treatment values. RESULTS Pre-treatment levels of both high-sensitivity C-reactive protein and fetuin-A were observed to be higher in the patient group than in the control group. The decrease in high-sensitivity C-reactive protein levels during the post-treatment stage was not statistically significant. However, the decrease observed in post-treatment fetuin-A levels was found to be statistically significant. CONCLUSION The decrease in fetuin-A levels in subclinical hypothyroidism cases indicates that levothyroxine treatment exerts anti-inflammatory and anti-apoptotic effects. Although the decrease in high-sensitivity C-reactive protein levels was statistically non-significant, it is predicted to reach significance with sustained treatment.
