Antimicrobial resistance gene shuffling and a three-element mobilisation system in the monophasic Salmonella typhimurium strain ST1030.

In this study we describe the genetic elements and the antimicrobial resistance units (RUs) harboured by the Salmonella Typhimurium monophasic variant 1,4,[5],12:i:- strain ST1030. Of the three identified RUs two were chromosomal, RU1 (IS26-blaTEM-1-IS26-strAB-sul2- IS26) and RU2 (IS26-tetR(B)-tetA(B)-ΔIS26), and one, RU3 (a sul3-associated class 1 integron with cassette array dfrA12-orfF-aadA2-cmlA1-aadA1), was embedded in a Tn21-derived element harboured by the conjugative I1 plasmid pST1030-1A. IS26 elements mediated the antimicrobial resistance gene (ARG) shuffling and this gave rise to pST1030-1A derivatives with different sets of ARGs. ST1030 also harboured two ColE1-like plasmids of which one, pST1030-2A, was mobilisable and the target of an intracellular translocation of the Tn21-derived element; the second (pST1030-3) was an orphan mob-associated oriT plasmid co-transferred with pST1030-1A and pST1030-2A. pST1030-2A and pST1030-3 also carried a parA gene and a type III restriction modification system, respectively. Overall analysis of our data reinforces the role played by IS26, Tn21-derived elements and non-conjugative plasmids in the spread of ARGs and supplies the first evidence, at least in Salmonella, for the identification of a natural isolate harbouring a three-element mobilisation system in the same cell.

Serum uric acid is not independently associated with plasma renin activity and plasma aldosterone in hypertensive adults.

BACKGROUND AND AIMS: In experimental investigations conducted in rats, raising serum uric acid (SUA) levels resulted in the stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship of SUA with plasma aldosterone concentration (PAC). The study aimed to assess the relationship between SUA levels, PRA, and PAC and the influence of age, gender, body mass index (BMI), and hyperuricemia on these relationships in subjects with essential hypertension (EH). METHODS AND RESULTS: We enrolled 372 hypertensive patients (mean age 45 ± 12 years, men 67%) with uncomplicated EH that was not pharmacologically treated. The study population was divided in tertiles according to SUA levels. While PRA did not differ significantly across the three tertiles, PAC was higher in subjects belonging to the uppermost tertile of SUA than those in the lower ones (p = 0.0429); however, this difference lost statistical significance after adjustment for age, sex, BMI, and serum creatinine. Univariate correlation analyses showed significant associations of SUA with PRA (r = 0.137; p = 0.008) and PAC (r = 0.179; p < 0.001). However, these relationships were not significant after correcting for confounding factors in multiple linear regression analyses. We did not observe statistically significant effect modification by gender, age, BMI, and hyperuricemia. CONCLUSION: SUA levels are weakly associated with PRA and PAC in adults with untreated EH. These relationships were lost after adjustment for age, sex, BMI, and serum creatinine.

Renal haemodynamics and severity of carotid atherosclerosis in hypertensive patients with and without impaired renal function.

BACKGROUND AND AIM: Renal resistance index (RRI), assessed by Duplex-Doppler sonography, has been classically considered as a mere expression of intrarenal vascular resistance. Recent studies, however, have showed that RRI is also influenced by upstream factors, especially arterial compliance, confirming its possible role as a marker of systemic vascular alterations. Several studies have shown that carotid intima-media thickness (cIMT) and carotid plaques (cP), assessed by ultrasonography, are documented markers of subclinical organ damage as well as expression of progressive atherosclerotic disease, and that they get worse with the progressive deterioration of renal function. The study was aimed to evaluate the relationship between RRI and severity of carotid atherosclerosis in hypertensive subjects with and without impaired renal function. METHODS AND RESULTS: The study population, including 263 hypertensive patients (30-70 years), was split into 3 groups based on cIMT and presence of cP (cIMT ≤ 0.9 mm and no cP; cIMT > 0.9 mm and no cP; cP). All patients were also divided into 2 subgroups (normal renal function; CKD stage I-IV). A stepwise increase in RRI corresponding to the groups of progressive severity of carotid atherosclerosis was observed (respectively 0.61 ± 0.07, 0.65 ± 0.06, 0.68 ± 0.06; p < 0.001). A strong positive correlation was observed between RRI and cIMT in the whole population (r = 0.43; p < 0.001) and in the subgroups with (r = 0.42; p < 0.001) and without (r = 0.39; p < 0.001) CKD. These associations remained statistically significant even after adjustment for various confounding factors. CONCLUSION: Showing a close association between RRI and severity of carotid atherosclerosis, our results strengthen the concept that RRI is a marker of systemic vascular changes.

Transcriptional regulation of enniatins production by Fusarium avenaceum.

AIMS: The aim of this study was to analyse the transcriptional regulation of enniatins (ENs) production in Fusarium avenaceum. METHODS AND RESULTS: We develop a new method to quantify ENs in FDM agar medium. We performed an LC/MS/MS analysis to evaluate enniatin A, A1, B, B1 and B4 production by seven F. avenaceum strains and, in a time-course experiment, by ITEM 3404 to analyse the transcriptional regulation of the esyn1 gene. The expression profile, achieved by Real time reverse transcriptase assay, showed an activation of gene transcription at the seventh day of incubation, corresponding to the higher increase of total ENs production. Enniatin B was the most abundant ENs analogues, representing the 90% of total ENs. The relative percentage of ENs remained unaltered during the experiment. CONCLUSIONS: We reported a transcriptional regulation of esyn1 responsible for the modulation of ENs biosynthesis. SIGNIFICANCE AND IMPACT OF THE STUDY: Enniatins are cyclic depsipeptides metabolites with a wide range of biological activities. They are also widespread contaminants in grains and cereals due to infection by enniatin-producing Fusarium species. This is the first article describing the transcriptional regulation of esyn1 gene that modulates ENs production in Fusarium avenaceum and provides new knowledge about the molecular mechanism underlying the biosynthesis of these important fungal metabolites in this toxigenic fungal species.

Relationships between mild hyperuricaemia and aortic stiffness in untreated hypertensive patients.

BACKGROUND AND AIMS: Clinical studies exploring the relationship between serum uric acid (SUA) and arterial stiffness yielded conflicting results. Only in a few of these studies, arterial distensibility was examined by measuring aortic pulse wave velocity (PWV), which is considered the gold standard for evaluating arterial stiffness. In none of the previous investigations was the influence of SUA on aortic distensibility assessed, taking into account the effect of albuminuria. The purpose of our study was to comprehensively analyse the relationships between SUA and aortic PWV in a group of essential hypertensive patients. METHODS AND RESULTS: We enrolled 222 untreated and uncomplicated hypertensive subjects (mean age: 44 ± 10 years; 60% males), without gout. In all patients, SUA and urinary albumin excretion rate (AER) were determined. Moreover, carotid-femoral (c-f) PWV was measured. C-f PWV was significantly higher in hypertensive patients belonging to the uppermost tertile of SUA distribution, compared to subjects of the lowest tertiles (10.9 ± 2.2 vs. 10 ± 1.8 vs. 9.9 ± 1.7 m s(-1); p = 0.001). In univariate analysis, SUA correlated with c-f PWV (r = 0.24; p < 0.001). This association disappeared when AER was added in a multiple regression model, including SUA, age, mean arterial pressure, gender, metabolic syndrome components and glomerular filtration rate. CONCLUSION: The results of our study showed that, in essential hypertensive subjects, there is a positive relationship between mild hyperuricaemia and aortic stiffness. This association weakened after adjustment for covariates and lost statistical significance after further correction for albuminuria.

DypB peroxidase for aflatoxin removal: New insights into the toxin degradation process.

Aflatoxin B1 (AFB1) is one of the most potent carcinogens and a widespread food and feed contaminant. As for other toxins, many efforts are devoted to find efficient and environmentally-friendly methods to degrade AFB1, such as enzymatic treatments, thus improving the safety of food and feed products. In this regard, the dye decolorizing peroxidase of type B (DypB) can efficiently degrade AFB1. The molecular mechanism, which is required to drive protein optimization in view of the usage of DypB as a mycotoxin reduction agent in large scale application, is unknown. Here, we focused on the role of four DypB residues in the degradation of AFB1 by alanine-scanning (residues 156, 215, 239 and 246), which were identified from biochemical assays to be kinetically relevant for the degradation. As a result of DypB degradation, AFB1 is converted into four products. Interestingly, the relative abundancy of these products depends on the replaced residues. Molecular dynamics simulations were used to investigate the role of these residues in the binding step between protein and manganese, a metal ion which is expected to be involved in the degradation process. We found that the size of the haem pocket as well as conformational changes in the protein structure could play a role in determining the kinetics of AFB1 removal and, consequently, guide the process towards specific degradation products.

Absence of an independent association between serum uric acid and left ventricular mass in Caucasian hypertensive women and men.

BACKGROUND AND AIM: Experimentally uric acid may induce cardiomyocyte growth and interstitial fibrosis of the heart. However, clinical studies exploring the relationship between serum uric acid (SUA) and left ventricular (LV) mass yielded conflicting results. The aim of our study was to evaluate the relationships between SUA and LV mass in a large group of Caucasian essential hypertensive subjects. METHODS AND RESULTS: We enrolled 534 hypertensive patients free of cardiovascular complications and without severe renal insufficiency. In all subjects routine blood chemistry, including SUA determination, echocardiographic examination and 24 h ambulatory blood pressure (BP) monitoring were obtained. In the overall population we observed no significant correlation of SUA with LV mass indexed for height(2.7) (LVMH(2.7)) (r = 0.074). When the same relationship was analysed separately in men and women, we found a statistically significant correlation in female gender (r = 0.27; p < 0.001), but not in males (r = -0.042; p = NS). When we grouped the study population in sex-specific tertiles of SUA, an increase in LVMH(2.7) was observed in the highest tertiles in women (44.5 ± 15.6 vs 47.5 ± 16 vs 55.9 ± 22.2 g/m(2.7); p < 0.001), but not in men. The association between SUA and LVMH(2.7) in women lost statistical significance in multiple regression analyses, after adjustment for age, 24 h systolic BP, body mass index, serum creatinine and other potential confounders. CONCLUSIONS: Our findings do not support an independent association between SUA and LV mass in Caucasian men and women with arterial hypertension.

Evaluation of the prevalence of dental agenesis through the use of orthopantomography in a sample of subjects residing in Lombardy and Piedmont regions.

AIM: Dental agenesis is one of the most frequent dental anomalies, with a prevalence varying from 1.6% to 36.5%, depending on the populations studied. The patient's age at diagnosis, sex, and ethnic differences are considered possible influenting factors that can explain such a wide range of prevalence. The objective of the study was to define the frequency of dental agenesis in a sample of subjects living in Piedmont and Lombardy regions of Italy. MATERIALS: X-rays, already taken for other diagnostic purposes, were collected. Orthopantomographies belonging to subjects born after 1995 and aged between 7.9 and 16.9 years were selected. It was assessed the presence of each tooth, except for third molars since they are frequently absent due to their variability. If a tooth was missing and the patient had additional radiographs, the other radiographs were evaluated to confirm the diagnosis or to rule out a delayed calcification or the presence of a malposition tooth. Results: Orthopantomographies were collected from 1,020 subjects and 98 of them presented agenesis, with a prevalence of 5% for females and 4.61% for males. The most affected teeth were 35 and 45, followed by 12 and 22. The lower arch was more frequently involved by agenesis: there were 107 teeth absent in the mandibular arch and 83 in the maxillary arch.

Young woman with branchio-oto-renal syndrome and a novel mutation in the EYA-1 gene.

Branchio-oto-renal (BOR) syndrome is an autosomal dominant disease clinically characterized by the coexistence of some or all of the following major disorders: deafness, cervical branchial fistulae, preauricular pits, and renal abnormalities. Most families with BOR syndrome have mutations on the EYA-1 gene on chromosome 8q. We present the case of a 23-year-old Italian woman without a familial history of BOR syndrome. The patient, who had hearing loss and a history of surgeries for correction of bilateral cervical branchial fistulae and bilateral preauricular pits, presented with renal impairment, hypertension and overt proteinuria. DNA sequencing showed a novel heterozygous mutation 1420-1421delCC in exon 14 of EYA-1 gene.

A low reported energy intake is associated with metabolic syndrome.

BACKGROUND AND AIMS: Metabolic syndrome (MS) may be associated with the presence of an energy-sparing metabolism that predisposes to the excess accumulation of body fat. This study examined the relationship between reported energy intake and obesity in individuals with and without MS. METHODS AND RESULTS: Ninety consecutive non-diabetic obese subjects were divided into 2 groups based on the presence (MS+: no.=50) or absence (MS-: no.=40) of MS. The study design was cross-sectional. The 3-day food record method was used to assess the subjects' usual energy intake and the Diet Readiness Test (DRT) was also administered. Compared to the MS- group, the MS+ group had a significantly higher body weight, body mass index (mean+/-SEM: 39.1+/-1.3 vs 31.5+/-0.9, p<0.001) and fat mass. The absolute energy intake of the MS+ group (8629+/-331 kJ/24h) did not differ from that of the MS- group (8571+/-515 kJ/24h; p=ns). The daily energy intake normalized for the fat-free mass (FFM) size was higher in the MS- group (163+/-8 kJ/kg-FFM x 24h) than in the MS+ group (138+/-4 kJ/kg-FFM x 24h; p<0.03). The DRT test results were similar in both groups except that section 6 (exercise patterns and attitudes) score was lower in the MS+ group (10.0+/-0.5) than in the MS- group (11.9+/-0.5; p<0.01). CONCLUSION: The results of this study support the hypothesis that subjects with MS have an energy-sparing metabolism.

Relationships between metabolic syndrome and left ventricular mass in hypertensive patients: does sex matter?

Several studies documented an association between metabolic syndrome (MetS) and left ventricular (LV) hypertrophy. However, only in a few of these studies the impact of MetS on left ventricular mass (LVM) was separately analysed by gender, with conflicting results. The aim of our study was to verify, in a wide sample of essential hypertensive patients, the influence of gender, if any, on the relationship between MetS and LVM. We enrolled 475 non-diabetic subjects (mean age: 46 +/- 11 years), with mild-to-moderate essential hypertension, of whom 40% had MetS, defined on the basis of Adult Treatment Panel III (ATPIII) criteria. All the patients underwent a 24-h ambulatory blood pressure monitoring and an echocardiogram. LVM indexed for height (2.7) (LVMH (2.7)) was significantly (P < 0.001) higher in women with MetS (n=83) than in those without it (n=97; 54+/-17 vs 42+/-11 g m(-2.7)). An equally significant difference in LVMH (2.7) was documented also in male gender between the two groups with (n=105) and without MetS (n=190; 51+/-14 vs 43+/-11 g m(-2.7); P < 0.001). The relationship between MetS and LVMH (2.7) remained statistically significant (P < 0.001) in both sexes, in multiple regression analyses, even after adjustment for potential confounding factors. Our results seem to suggest that the relationship between MetS and LVM is not significantly affected by gender, being LVM increased in both hypertensive women and men with MetS.

Cryptic subspecies and beauvericin production by Fusarium subglutinans from Europe.

Fusarium subglutinans is a maize ear rot pathogen and producer of beauvericin and other mycotoxins. This species has recently been split into two major phylogenetic within-species groups based on RFLP DNA sequence polymorphisms identified in the histone H3 and beta-tubulin sequences. A Pan European collection of the fungus originating mostly from maize was subjected to phylogenetic analysis by RFLP grouping and to chemical analysis for beauvericin production. Of the 62 isolates belonging to Group 1, 48 (77%) produced from 10 to 532 microg/g of beauvericin, whereas none of the 39 Group 2 isolates synthesized detectable amounts of the mycotoxin. The association between RFLP group and beauvericin production is consistent with the existence of two reproductively isolated subgroups within F. subglutinans and indicates that the toxicological risk of isolates of F. subglutinans depends on the group with which they are affiliated.

Relationship between the fungal complex causing Fusarium head blight of wheat and environmental conditions.

ABSTRACT Over 4 years, the environmental conditions and the causal agents of Fusarium head blight (FHB) disease of wheat were determined in field sites in four European countries: Hungary, Ireland, Italy, and the United Kingdom. Polymerase chain reaction-based methods were used to detect each species causing FHB and quantify its DNA (as a measurement of fungal abundance) in the samples. Canonical correspondence analysis (CCA) was used to determine the relationship of the incidence and abundance of each species with weather variables. CCA indicated that little variability in the species prevalence data was explained by the weather variables. In contrast, a greater proportion of variability in abundance data was accounted for by the weather variables. Most samples contained two or more species and statistical analysis suggested that these species tended to coexist at field sites. CCA also indicated that there were differences in the relationships of the prevalence and abundance of the six FHB species with environmental variables. Fusarium poae was associated with relatively drier and warmer conditions, whereas F. graminearum was associated with warmer/humid conditions. F. avenaceum and F. culmorum were both associated with niches of cooler/wet/humid conditions. Two Microdochium species were associated with regions of relatively cool/moderate temperatures and frequent rainfalls of short duration. The results also suggested that environmental conditions differentially affect the infection and colonization processes, and the comparative abundance of the six species.

Application of a recombinant laccase-chlorogenic acid system in protein crosslink and antioxidant properties of the curd.

Milk protein crosslink through the action of enzymes represents a feasible strategy to impart new functionalities to cheese. In this work we reported the effects of a laccase mediator system (LMS) on protein crosslink and antioxidant property of curd. The crosslinking activity of a purified recombinant laccase Ery4 and a commercial enzyme preparation (cLC), with three mediators was firstly evaluated in milk and then applied before curd manufacture. Only Ery4-LMS significantly increased curd weight compared to that of the control sample. SDS-PAGE revealed that similar high molecular weight bands produced by both LMSs in milk were also retained in curds. The antioxidant activity recorded in curds with Ery4-LMS was the highest among all samples both before and after gastro-pancreatic digestion. This is the first time that a CGA-based LMS is used in manufacture of curd with improved antioxidant properties. These results open new perspectives for dairy applications.

Microalbuminuria and early endothelial activation in essential hypertension.

We hypothesized that in essential hypertensive patients (EHs), plasma levels of pro-atherogenic adhesion molecules would be increased and related with urine albumin excretion (UAE). Thus, this study was aimed at evaluating biochemical markers of endothelial activation and their relationship with UAE in a group of patients with uncomplicated EH. In basal condition soluble forms of adhesion molecules intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1, as well as 24-h UAE were assayed. One hundred patients with essential hypertension and no diabetes or ultrasonographic evidence of atherosclerosis were included in the study. Seventy normotensive healthy subjects served as controls. EHs were first studied overall, than were divided into two subgroups: those with UAE > or =20 mcg/min MAUs and those with UAE <20 mcg/min (non-MAUs). ICAM-1 (P<0.001) and VCAM-1 (P<0.0001) plasma concentrations were higher in EHs than in controls. Microalbuminuric EHs had greater levels of adhesion molecules than non-MAUs (ICAM-1 P=0.04; VCAM-1 P=0.02, respectively). In EHs UAE was correlated with ICAM-1 (r=0.29, P=0.003), and VCAM-1 (r=0.30, P=0.002). These associations were confirmed in multiple regression models (P=0.02 for both ICAM-1 and VCAM-1) including, along with adhesion molecules, age, body mass index and blood pressures. Our findings show that in essential hypertension there is a very early activation of endothelial adhesion molecules favouring atherosclerosis.

Metabolic syndrome in subjects with white-coat hypertension: impact on left ventricular structure and function.

Some reports have suggested that white-coat hypertension (WCH) is associated with some features of the metabolic syndrome (MetS). These metabolic disturbances, instead of WCH per se, may potentially explain the greater extent of end-organ damage sometimes observed in WCH subjects (WCHs) when compared to normotensive individuals (NTs). The aim of the present cross-sectional study was to compare left ventricular (LV) structure and function in three groups of subjects: WCHs with MetS, WCHs without MetS and NTs. A total of 145 WCHs, 35% of whom had MetS, were enrolled. As controls, 35 NTs were also studied. In all subjects, routine blood chemistry, echocardiographic examination and 24-h ambulatory blood pressure monitoring were performed. When compared with WCHs without MetS, those with MetS showed higher LV mass indexed by height elevated by a power of 2.7 (LVMH(2.7)) (49.6+/-14.8 vs 38.9+/-9.8 g/m(2.7); P<0.0001). The same parameter was greater in WCHs without MetS than in NTs (32+/-8 g/m(2.7); P=0.004). Moreover, the E-wave deceleration time was longer in WCHs with MetS than in those without it (236.2+/-66.4 vs 200.5+/-30.8 ms; P<0.0001). The relationship of MetS with LVMH(2.7) was confirmed in multivariate regression models. Our results seem to suggest that MetS may have a deleterious influence on LV structure and function in WCH. However, WCH, being associated with an increased LV mass, also in subjects without MetS, may not be considered as an innocuous phenomenon.

Biodiversity of complexes of mycotoxigenic fungal species associated with Fusarium ear rot of maize and Aspergillus rot of grape.

Fusarium ear rot of maize and Aspergillus rot of grape are two examples of important plant diseases caused by complexes of species of mycotoxigenic fungi. These complexes of species tend to be closely related, produce different classes of mycotoxins, and can induce disease under different environmental conditions. The infection of maize and grape with multiple fungal species and the resulting production of large classes of mycotoxins is an example of mutual aggressiveness of microorganisms toward host species as well as to humans and animals that eat feed or food derived from the infected and contaminated plants. Infection of crop plant with a complex of microbial species certainly represents a greater threat to a crop plant and to human and animal health than infection of the plant with a single fungal species.

Further data on the production of beauvericin, enniatins and fusaproliferin and toxicity to Artemia salina by Fusarium species of Gibberella fujikuroi species complex.

The knowledge of toxigenic profiles of fungal plant pathogens is of extreme importance for evaluating the potential toxicity of infected plant products. Ninety-six fungal isolates belonging to 28 species in the Gibberella fujikuroi complex were studied for the production of beauvericin, enniatins and fusaproliferin in rice cultures. Toxin production ranged from 5 to 3000 microg/g for beauvericin, 2 to 131 microg/g for enniatins, and 4 to 440 microg/g for fusaproliferin. Beauvericin was the most common metabolite produced by 16 species followed by fusaproliferin with 11 species and enniatins with 4 species. The production of beauvericin by F. bulbicola, F. denticulatum, F. lactis, F. phyllophilum, F. pseudocircinatum, and F. succisae and fusaproliferin by F. antophilum, F. begoniae, F. bulbicola, F. circinatum, F. concentricum, F. succisae, and F. udum is reported here for the first time. Brine shrimp larvae were most sensitive to culture extracts of F. acutatum (up to 94+/-3%), F. concentricum (up to 99+/-1%), F. denticuatum (up to 100%) and F. sacchari (up to 100%). Toxicity towards brine shrimp was significantly correlated with the beauvericin content of the fungal extracts with few exceptions. These data indicate that beauvericin and fusaproliferin are common metabolites of species of the G. fujikuroi complex and pose a risk for a possible toxin accumulation in their respective host plant products. However, data from the brine shrimp bioassay showed that further toxic metabolites within this complex need to be characterized.

Association between biomarkers of inflammation and left ventricular hypertrophy in moderate chronic kidney disease.

AIMS: Left ventricular hypertrophy (LVH) is a predictor for cardiovascular mortality, and it is considered to be a surrogate marker of preclinical cardiovascular disease. This study aimed at evaluating whether fetuin-A plasma levels are decreased in patients with moderate chronic kidney disease (CKD) and their linkage to plasma concentrations of hs-C-reactive protein (CRP), cardiotrophyn-1 (CT-1), tumor necrosis factor-ac (TNF-alpha), propeptide of collagen Type I (PIP) and to LVH. MATERIAL AND METHODS: We enrolled 64 moderate CKD and 55 essential hypertensives (EH) with normal renal function as controls. All the patients underwent an echocardiographic examination; plasma samples were obtained to measure routine clinical parameters and the molecules listed above (measured by ELISA). RESULTS: Among CKD there were 30/64 patients with LVH, and in EH group 14/55 subjects had LVH. Fetuin A was reduced in CKD when compared with EH (p < 0.0001). The comparison between CKD having LVH with those without LVH showed significant differences in plasma levels of fetuin-A (p < 0.002), TNF-alpha (p < 0.01) and hs-CRP (p < 0.001), CT-1 and PIP (p < 0.002). CKD with LVH had lower values of fetuin-A (p < 0.001), and higher values of hs-CRP (p < 0.001) TNF-alpha (p < 0.001), CT-1 (p < 0.001) and PIP (p < 0.001) than EH with LVH. The multivariate analysis of correlation demonstrated that in CKD patients hs-CRP (beta 0.42, p < 0.00006), and systolic blood pressure (beta 0.29, p < 0.02) were independent predictors of LV mass index. The relationship between LV mass index and fetuin-A did not reach statistical significance. CONCLUSIONS: For the first time in moderate CKD patients, we demonstrate that fetuin-A is decreased and relates to LVH depending on C-reactive protein.
