Abstract
BACKGROUND Elevated white blood cell count, fibrinogen levels, and lower levels of albumin signify higher systemic inflammatory response, hypercoagulable state, and poorer nutritional status, respectively. However, a consistent conclusion could not be drawn on whether the association between inflammatory markers and cardiovascular disease was affected by the presence of chronic kidney disease (CKD). We aimed to explore the association between inflammation and adverse outcomes in patients with acute ischemic stroke (AIS), as well as whether this association differs due to the presence of CKD. METHODS AND RESULTS This research was based on the Third China National Stroke Registry. The main adverse outcomes were poor functional outcome, stroke recurrence, and combined vascular event after 1 year. Inflammation was defined as the worst quartile of at least 2 of the aforementioned 3 markers. Finally, 8493 patients with AIS were enrolled in this study. The adjusted odds ratios/hazard ratios and 95% CIs of inflammation were 1.58 (1.34-1.86) for poor functional outcomes, 1.25 (1.06-1.47) for stroke recurrence, and 1.25 (1.06-1.46) for combined vascular event. The association between inflammation and adverse outcomes existed only in patients with AIS without CKD, although the interaction between CKD and inflammation was not statistically significant. (P for interaction >0.05). CONCLUSIONS Inflammation, which was defined as a combination of fibrinogen, white blood cell count, and albumin, was associated with all 1-year adverse outcomes among patients with AIS. Routine assessment of these biomarkers could become a potential part of the clinical evaluation for patients with AIS, especially those without CKD, aiding clinicians in risk stratification and treatment decision-making.

Transl Res 2023; 256:87-94. [PMID: 36586535 PMCID: PMC10101890 DOI: 10.1016/j.trsl.2022.12.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 12/21/2022] [Accepted: 12/22/2022] [Indexed: 12/29/2022]
Abstract
Chronic kidney disease (CKD) was responsible for 1.2 million deaths globally in 2016. Despite the large and growing burden of CKD, treatment options are limited and generally only preserve kidney function. Characterizing molecular precursors to incident and progressive CKD could point to critically needed prevention and treatment strategies. Clonal hematopoiesis of indeterminate potential (CHIP) is typically characterized by the clonal expansion of blood cells carrying somatic mutations in specific driver genes. An age-related disorder, CHIP is rare in the young but common in older adults. Recent studies have identified causal associations between CHIP and atherosclerotic cardiovascular disease which are most likely mediated by inflammation, a hallmark of CKD. Animal evidence has supported causal effects of CHIP on kidney injury, inflammation, and fibrosis, providing impetus for human research. Although prospective epidemiologic studies investigating associations of CHIP with development and progression of CKD are few, intriguing findings have been reported. CHIP was significantly associated with kidney function decline and end stage kidney disease in the general population, although effect sizes were modest. Recent work suggests larger associations of CHIP with kidney disease progression in CKD patients, but further investigations in this area are needed. In addition, the accumulating literature has identified some heterogeneity in associations between CHIP and kidney endpoints across study populations, but reasons for these differences remain unclear. The current review provides an in-depth exploration into this nascent area of research, develops a conceptual framework linking CHIP to CKD, and discusses the clinical and public health implications of this work.

Hepatocyte Nuclear Factor-1α Increases Fibrinogen Gene Expression in Liver and Plasma Fibrinogen Concentration in Rats with Experimental Chronic Renal Failure. Int J Mol Sci 2023; 24:ijms24065733. [PMID: 36982805 PMCID: PMC10052989 DOI: 10.3390/ijms24065733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/13/2023] [Accepted: 03/15/2023] [Indexed: 03/19/2023] Open
Abstract
Chronic kidney disease (CKD) is associated with elevated plasma fibrinogen concentration. However, the underlying molecular mechanism for elevated plasma fibrinogen concentration in CKD patients has not yet been clarified. We recently found that HNF1α was significantly upregulated in the liver of chronic renal failure (CRF) rats, an experimental model of CKD in patients. Given that the promoter region of the fibrinogen gene possesses potential binding sites for HNF1α, we hypothesized that the upregulation of HNF1α can increase fibrinogen gene expression and consequently plasma fibrinogen concentration in the experimental model of CKD. Here, we found the coordinated upregulation of Aα-chain fibrinogen and Hnfα gene expression in the liver and elevated plasma fibrinogen concentrations in CRF rats, compared with pair-fed and control animals. Liver Aα-chain fibrinogen and HNF1α mRNAs levels correlated positively with (a) liver and plasma fibrinogen levels and (b) liver HNF1α protein levels. The positive correlation between (a) liver Aα-chain fibrinogen mRNA level, (b) liver Aα-chain fibrinogen level, and (c) serum markers of renal function suggest that fibrinogen gene transcription is closely related to the progression of kidney disease. Knockdown of Hnfα in the HepG2 cell line by small interfering RNA (siRNA) led to a decrease in fibrinogen mRNA levels. Clofibrate, an anti-lipidemic drug that reduces plasma fibrinogen concentration in humans, decreased both HNF1α and Aα-chain fibrinogen mRNAs levels in (a) the liver of CRF rats and (b) HepG2 cells. The obtained results suggest that (a) an elevated level of liver HNF1α can play an important role in the upregulation of fibrinogen gene expression in the liver of CRF rats, leading to an elevated concentration of plasma fibrinogen, a protein related to the risk of cardiovascular disease in CKD patients, and (b) fibrates can decrease plasma fibrinogen concentration through inhibition of HNF1α gene expression.

Abstract
BACKGROUND An unconventional risk factor, "dysfunction of hemodialysis vascular access", was demonstrated to be associated with subsequent major adverse cardiovascular events (MACE) in our previous study. However, applying this suggestion in a clinical scenario may be not intuitive. A group-based trajectory model was applied to further recognize those patients with the highest risks for MACE.Methods and Results:In a cohort of patients who received hemodialysis from 2001 to 2010, we identified 9,711 cases that developed MACE in the stage of stable maintenance dialysis, and 19,422 randomly selected controls matched to cases on age, gender and duration of dialysis. Events of vascular access dysfunction in the 6-month period before MACE for cases and index dates for controls were evaluated. By group-based trajectory modeling, patients according to their counts of vascular access dysfunction in each month over the 6-month period prior to MACE or index dates were categorized. There were 26,744 patients in group 1 (no dysfunction), 650 in group 2 (escalating dysfunction) and 1,739 in group 3 (persistent dysfunction). Logistic regression analysis indicated that patients in group 3 had the highest chance of subsequent MACE (odds ratio 2.47, in comparison with group 1) after controlling for all the available potential confounders. CONCLUSIONS Uninterrupted clusters of vascular access dysfunction are associated with a higher risk of subsequent MACE.

Plasma Leucine-Rich α-2-Glycoprotein 1 Predicts Cardiovascular Disease Risk in End-Stage Renal Disease. Sci Rep 2020; 10:5988. [PMID: 32249825 PMCID: PMC7136266 DOI: 10.1038/s41598-020-62989-7] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Accepted: 03/17/2020] [Indexed: 11/17/2022] Open
Abstract
Plasma leucine-Rich α-2-glycoprotein 1 (LRG1) is an innovative biomarker for inflammation and angiogenesis. Many adverse pathophysiological changes including inflammation, atherosclerosis, and premature mortality is associated with End-stage renal disease (ESRD). However, whether levels of plasma LRG1 correlate with the co-morbidities of ESRD patients is unknown. Plasma LRG1 and high-sensitivity C-reactive protein (hsCRP) were analyzed by ELISA in 169 hemodialysis patients from the Immunity in ESRD (iESRD) study. Patient demographics and comorbidities at the time of enrollment were recorded. Peripheral blood monocyte and T cell subsets were assessed by multicolor flow cytometry. In the univariate analysis, a higher level of LRG1 was associated with the presence of cardiovascular disease (CVD) and peripheral arterial occlusive disease (PAOD). In multivariate logistic regression models, higher LRG1 tertile was significantly associated with PAOD (odds ratio = 3.49) and CVD (odds ratio = 1.65), but not with coronary artery disease, history of myocardial infarction, or stroke after adjusting for gender, diabetes, hemoglobin, albumin, calcium-phosphate product, and level of hsCRP. In addition, the level of LRG1 had a positive correlation with IL-6, hsCRP, and also more advanced T cell differentiation. The association suggests that LRG1 participates in the progression of atherosclerosis by inducing inflammation. Therefore, the role of LRG1 in coexisting inflammatory response should be further investigated in the pathogenesis of cardiovascular morbidity and mortality in patients with ESRD.

Abstract
INTRODUCTION Interleukin (IL)-1β, as a key biomarker and mediator of vascular calcification in patients with end-stage renal disease (ESRD), may be involved in the process of premature senescence of vascular smooth muscle cells (VSMCs). This work sought to investigate whether IL-1β-induced premature senescence contributes to the process of osteoblastic transition and vascular calcification in VSMCs. METHODS Eighty-eight patients with ESRD (aged 25-81 years), 11 healthy individuals, and 15 cases of lesion-free distal radial arteries from dialysis ESRD patients with angiostomy were collected in this study. Immunohistochemical analysis was performed to detect expression of IL-1β, p21, and bone morphogenetic protein-2 (BMP2) in the distal radial arteries. Primary human VSMCs from healthy neonatal umbilical cords were incubated with test agents for 1-3 days. Intracellular levels of reactive oxygen species (ROS) and senescence-associated-β-galactosidase (SA-β-gal) staining were used to detect senescent cells. Alizarin red staining and the calcium content of the cell layer were used to detect mineral deposition in VSMCs. RESULTS Coincident with positive staining of IL-1β, p21, and BMP2 in the lesion-free distal radial arteries, 66.67% patients showed mineral deposition. Serum IL-1β was 0.24 ± 0.57, 1.20 ± 2.95, and 9.41 ± 40.52 pg/mL in 11 healthy individuals, 20 patients without calcification, and 53 patients with calcification, respectively. Analysis of the cross-table chi-square test showed cardiovascular calcification is not correlated with levels of serum IL-1β in patients with ESRD (p = 0.533). In response to IL-1β, VSMCs showed a senescence-like phenotype, such as flat and enlarged morphology, increased expression of p21, an increased activity of SA-β-gal, and increased levels of ROS. IL-1β-induced senescence of VSMCs was required for the activation of IL-1β/NF-κB/p53/p21 signaling pathway. IL-1β-induced senescent VSMCs underwent calcification due to osteoblastic transition mainly depending upon the upregulation of BMP2. Resveratrol, an activator of sirtuin-1, postponed the IL-1β-induced senescence through blocking the NF-κB/p53/p21 pathway and attenuated the osteoblastic transition and calcification in VSMCs. CONCLUSIONS High levels of IL-1β in medial smooth muscles of arteries may play roles in inducing senescence-associated calcification. IL-1β-induced senescence depending on the activation of the NF-κB/p53/p21 signaling pathway and contributing to osteoblastic transition of VSMCs.

Abstract
The biological perturbations associated with incident mortality are not well elucidated, and there are limited biomarkers for the prediction of mortality. We used a novel high‐throughput proteomics approach to identify serum peptides and proteins associated with 5‐year mortality in community‐dwelling men age ≥65 years who participated in a longitudinal observational study of musculoskeletal aging (Osteoporotic Fractures in Men: MrOS). In a discovery phase, serum specimens collected at baseline in 2473 men were analyzed using liquid chromatography–ion mobility–mass spectrometry, and incident mortality in the subsequent 5 years was ascertained by tri‐annual questionnaire. Rigorous statistical methods were utilized to identify 56 peptides (31 proteins) that were associated with 5‐year mortality. In an independent replication phase, selected reaction monitoring was used to examine 21 of those peptides in baseline serum from 750 additional men; 81% of those peptides remained significantly associated with mortality. Mortality‐associated proteins included a variety involved in inflammation or complement activation; several have been previously linked to mortality (e.g., C‐reactive protein, alpha 1‐antichymotrypsin) and others are not previously known to be associated with mortality. Other novel proteins of interest included pregnancy‐associated plasma protein, VE‐cadherin, leucine‐rich α‐2 glycoprotein 1, vinculin, vitronectin, mast/stem cell growth factor receptor, and Saa4. A panel of peptides improved the predictive value of a commonly used clinical predictor of mortality. Overall, these results suggest that complex inflammatory pathways, and proteins in other pathways, are linked to 5‐year mortality risk. This work may serve to identify novel biomarkers for near‐term mortality.

Abstract
BACKGROUND/AIMS Normal myocardial perfusion is closely associated with very low rates of cardiac events and better long-term outcomes; however, little is known about its prognostic value in patients with end-stage renal disease (ESRD). METHODS A total of 286 incident patients underwent baseline cardiac evaluations using echocardiography and stress-rest single-photon emission computed tomography. Perfusion scans for 177 patients (61.9%) who had a summed stress score (SSS) < 4 were normal. RESULTS During the 4-year follow-up period, 79 cardiac events occurred. Patients with a SSS < 4 had significantly lower annual rates of cardiac events than did those with a SSS ≥ 4 (6.4% vs. 13.2%; hazard ratio, 0.54; 95% confidence interval, 0.31 to 0.94). Among patients with a SSS < 4, however, cardiac event rates significantly differed according to the presence of comorbid conditions such as old age, diabetes, history of coronary artery disease, and elevated C-reactive protein levels. In addition, the presence of left ventricular (LV) systolic dysfunction and LV hypertrophy at the start of hemodialysis strongly influenced future cardiac events. CONCLUSIONS In patients with ESRD, normal perfusion scans usually indicate a significantly low risk of adverse cardiac events. However, even in patients with normal perfusion scans, the cardiovascular prognosis is largely dependent on baseline inflammation levels and comorbidities.

Abstract
Inter-organ crosstalk plays an essential role in the physiological homeostasis of the heart and other organs, and requires a complex interaction between a host of cellular, molecular, and neural factors. Derangements in these interactions can initiate multi-organ dysfunction. This is the case, for instance, in the heart or kidneys where a pathological alteration in one organ can unfavorably affect function in another distant organ; attention is currently being paid to understanding the physiopathological consequences of kidney dysfunction on cardiac performance that lead to cardiorenal syndrome. Different cardiorenal connectors (renin-angiotensin or sympathetic nervous system activation, inflammation, uremia, etc.) and non-traditional risk factors potentially contribute to multi-organ failure. Of these, inflammation may be crucial as inflammatory cells contribute to over-production of eicosanoids and lipid second messengers that activate intracellular signaling pathways involved in pathogenesis. Indeed, inflammation biomarkers are often elevated in patients with cardiac or renal dysfunction. Epigenetics, a dynamic process that regulates gene expression and function, is also recognized as an important player in single-organ disease. Principal epigenetic modifications occur at the level of DNA (i.e., methylation) and histone proteins; aberrant DNA methylation is associated with pathogenesis of organ dysfunction through a number of mechanisms (inflammation, nitric oxide bioavailability, endothelin, etc.). Herein, we focus on the potential contribution of inflammation in pathogenesis of cardiorenal syndrome.

Abstract
BACKGROUND Rheumatoid arthritis (RA), a prototypic systemic autoimmune inflammatory condition, confers an increased risk of cardiovascular disease (CVD). Recently, chronic kidney disease (CKD) was suggested to increase the risk of CVD in RA patients, and inflammation was identified as a critical, nontraditional CKD-associated risk factor for CVD. This study aimed to examine the combined effects of CKD and CVD in RA patients. METHODS In this retrospective evaluation of 428 RA patients, the outcome of interest was the incidence of CVD. CKD was defined as an estimated glomerular filtration rate of <60mL/min/1.73m2 and/or positive dipstick tests for proteinuria of ≥3 months duration. C-reactive protein (CRP) was used as an inflammation marker, and a high CRP level was defined as a mean CRP value of ≥0.57mg/dL during the first 6 months of follow-up. Patients were categorized as follows: non-CKD with low CRP, non-CKD with high CRP, CKD with low CRP, and CKD with high CRP. RESULTS During a median follow-up of 89 months, 67 patients (16%) had CKD, and 38 (9%) developed CVD. Using patients with non-CKD and low CRP as a reference group, the adjusted hazard ratios (HR, 95% confidence interval) for CVD were 1.88 (0.25-9.44) for patients with CKD/low CRP and 9.71 (3.27-31.97) for those with CKD/high CRP. CONCLUSIONS The coexistence of CKD and inflammation was associated with a higher risk of CVD than either condition alone in RA patients. Inflammation might increase the risk of CVD especially in patients with CKD.

Abstract
BACKGROUND We studied the association of inflammatory biomarkers including C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) with chronic kidney disease (CKD). METHODS We conducted a case-control study among 201 CKD patients and 201 community-based controls in the greater New Orleans area. CKD was defined as estimated-glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2) or albuminuria ≥30 mg/24-h. Serum CRP, TNF-α, and IL-6 were measured using standard methods. Multivariable regression models were used to examine associations between the inflammatory biomarkers and CKD adjusting for important CKD risk factors, history of cardiovascular disease, and use of antihypertensive, antidiabetic, and lipid-lowering agents and aspirin. RESULTS The multivariable-adjusted medians (interquartile-range) were 2.91 (1.47, 5.24) mg/L in patients with CKD vs. 1.91 (0.99, 3.79) mg/L in controls without CKD (p = 0.39 for group difference) for CRP; 1.86 (1.51, 2.63) pg/mL vs. 1.26 (1.01, 1.98) pg/mL (p < 0.0001) for TNF-α; and 2.53 (1.49, 4.42) pg/mL vs. 1.39 (0.95, 2.15) pg/mL (p = 0.04) for IL-6, respectively. Compared to the lowest tertile, the highest tertile of TNF-α (OR 7.1, 95% CI 3.2 to 15.5) and IL-6 (OR 2.5, 95% CI 1.1 to 5.5) were significantly associated with higher odds of CKD in multivariable-adjusted models. Additionally, higher TNF-α and IL-6 were independently and significantly associated with lower eGFR and higher albuminuria. CONCLUSIONS Our data suggest that TNF-α and IL-6, but not CRP, are associated with the prevalence and severity of CKD, independent from established CKD risk factors, history of cardiovascular disease, and use of antihypertensive, antidiabetic, and lipid-lowering agents and aspirin.

Abstract
BACKGROUND AND OBJECTIVES High levels of serum polyclonal combined Ig free light chains are associated with inflammation and decreased excretory kidney function, and they are an independent risk factor for mortality. Whether combined Ig free light chain predicted mortality and progression to ESRD in a stages 3-5 CKD cohort was assessed. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This was a prospective cohort study of 872 patients with stages 3-5 CKD (nondialysis) recruited into the Chronic Renal Insufficiency Standards Implementation Study. Patients were recruited to the Chronic Renal Insufficiency Standards Implementation Study in an unselected manner from secondary care nephrology clinics between 2004 and 2010. Combined Ig free light chain was measured at recruitment and analyzed by quartiles. The cohort was followed up for a median of 41.4 months (interquartile range =28.3-68.0 months). Cox regression analysis was undertaken to determine the variables associated with mortality and progression to ESRD. RESULTS Combined Ig free light chain quartiles were <49.4, 49.4-68.8, 68.9-100.7, and >100.7 mg/L. An independent association with death and progression to ESRD was associated with the third and fourth combined Ig free light chain quartiles (quartile 3: death: hazard ratio, 1.49; 95% confidence interval, 1.02 to 2.18; P=0.04; ESRD: hazard ratio, 1.72; 95% confidence interval, 1.0 to 2.97; P=0.05; quartile 4: death: hazard ratio, 1.99; 95% confidence interval, 1.34 to 2.93; P<0.001; ESRD: hazard ratio, 3.73; 95% confidence interval, 2.1 to 6.3; P<0.001). The other independent risk factors were (1) preexisting cardiovascular disease, age >65 years old, and eGFR=15-30 ml/min per 1.73 m(2) for death and (2) age ≤65 years old, eGFR<30 ml/min per 1.73 m(2), urinary protein-to-creatinine ratio >30 mg/mmol, and serum phosphate level >4.65 mg/dl for progression to ESRD. CONCLUSIONS An elevated serum combined Ig free light chain level is an independent risk factor for mortality and progression to ESRD in patients with stages 3-5 CKD managed in secondary care.

Abstract
Chronic kidney disease (CKD) has been shown to be an independent risk factor for cardiovascular events. In addition, patients with pre-dialysis CKD appear to be more likely to die of heart disease than of kidney disease. CKD accelerates coronary artery atherosclerosis by several mechanisms, notably hypertension and dyslipidemia, both of which are known risk factors for coronary artery disease. In addition, CKD alters calcium and phosphorus homeostasis, resulting in hypercalcemia and vascular calcification, including the coronary arteries. Mortality of patients on long-term dialysis therapy is high, with age-adjusted mortality rates of about 25% annually. Because the majority of deaths are caused by cardiovascular disease, routine cardiac catheterization of new dialysis patients was proposed as a means of improving the identification and treatment of high-risk patients. However, clinicians may be uncomfortable exposing asymptomatic patients to such invasive procedures like cardiac catheterization, thus noninvasive cardiac risk stratification was investigated widely as a more palatable alternative to routine diagnostic catheterization. The effective management of coronary artery disease is of paramount importance in uremic patients. The applicability of diagnostic, preventive, and treatment modalities developed in nonuremic populations to patients with kidney failure cannot necessarily be extrapolated from clinical studies in non-kidney failure populations. Noninvasive diagnostic testing in uremic patients is less accurate than in nonuremic populations. Initial data suggest that dobutamine echocardiography may be the preferred diagnostic method. PCI with stenting is a less favorable alternative to CABG, however, it has a faster recovery time, reduced invasiveness, and no overall mortality difference in nondiabetic and non-CKD patients compared with CABG. CABG is associated with reduced repeat revascularizations, greater relief of angina, and increased long term survival. However, CABG is associated with a higher incidence of post-operative risks. The treatment chosen for each patient should be an individualized decision based upon numerous risk factors. CKD is associated with higher rates of CAD, with 44% of all-cause mortality attributable to cardiac disease and about 20% from acute MI. Optimal treatment including aggressive lifestyle modifications and concomitant medical therapy should be implemented in all patients to maximize benefits from either PCI or CABG. Future prospective randomized controlled trials with newer second or third generation DES and bioabsorbable DES are necessary to determine if PCI may be non-inferior to CABG in the future.

Abstract
Diabetic nephropathy is the most common cause of CKD and represents a large and ominous public health problem. Patients with diabetic kidney disease have exceptionally high rates of cardiovascular morbidity and mortality. In fact, the excess mortality among patients with diabetes appears to be largely limited to the subgroup with kidney disease and explained by their high burden of cardiovascular disease. The mechanisms underlying the strong association between diabetic kidney disease and various forms of cardiovascular disease are poorly understood. Traditional risk factors for cardiovascular disease, although prevalent among those with diabetes, do not fully account for the heightened risk observed. Despite their susceptibility to cardiovascular disease, patients with CKD are less likely to receive appropriate risk factor modification than the general population. Moreover, because patients with CKD have commonly been excluded from major cardiovascular trials, the evidence for potential treatments remains limited. The mainstays of treatment for diabetic kidney disease currently include blockade of the renin-angiotensin-aldosterone system and control of hypertension, hyperglycemia, and dyslipidemia. Increased awareness of the vulnerability of this patient population and more timely interventions are likely to improve outcomes while large evidence gaps are filled with newer studies.

Abstract
UNLABELLED BACKGROUND End-stage renal disease patients have significant cardiovascular morbidity and mortality, but little is known about differences in coagulation profiles between patients on hemodialysis (HD) and on peritoneal dialysis (PD). Given their long-term exposure to glucose-based dialysate, patients on PD can experience metabolic derangements. Theoretically, that exposure should create a more prothrombotic environment than occurs in HD patients. The objective of the present study was to quantify potential differences in baseline coagulation between PD and HD patients. ♢ METHODS Our single-center cross-sectional study at a large academic health science center enrolled 50 age-, race-, and sex-matched subjects (10 control subjects, 20 HD patients, and 20 PD patients). Measurements included platelet function, platelet receptor distribution, and coagulation dynamics by thromboelastography and Hemodyne hemostasis assay (Hemodyne, Richmond, VA, USA). ♢ RESULTS Compared with healthy control subjects, patients on both forms of dialysis showed prothrombotic coagulation protein profiles. The tissue-factor pathway was markedly elevated in both groups, but PD was associated with significantly greater concentrations of tissue factor (p = 0.0056) and tissue-factor pathway inhibitor (p = 0.0138). Similarly, compared with patients receiving HD, patients on PD had greater concentrations of fibrinogen (p = 0.0325), which corresponded with platelet hyperfunction as measured by platelet contractile force and clot elastic modulus (p = 0.003 and 0.017 respectively, compared with values in HD patients). Platelet receptor distribution was similar between the groups. ♢ CONCLUSIONS Compared with patients on HD, patients on PD appear to have a more prothrombotic profile. The clinical relevance of these findings needs to be studied in a prospective manner.

Abstract
Introduction: The determination of inflammation markers in circulation has enabled an important improvement in the study of cardiovascular diseases. It was tested the hypothesis that non-specific markers such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and fibrinogen may provide prognostic information in patients with acute myocardial infarction with persistent ST-segment elevation (STEMI) undergoing primary angioplasty (PCI). Methods: Patients: A cohort of 197 consecutive patients with STEMI undergoing primary PCI was enrolled, evaluating during hospitalization, the peak values of the following markers of inflammation: ESR, CRP and fibrinogen. A telephone follow-up has been made in order to investigate any possible new cardiovascular events after hospital discharge and the procedure performed. Results: Higher values of CRP were statistically associated with adverse future events as composite endpoint and with the single endpoint of death. Furthermore, higher age, presence of hypertension, history of previous cardiovascular events, were statistically significantly associated with cardiac events at follow up. In this group were also overrepresented subjects with anterior myocardial infarction in the anterior localization and with an EF ≤ 35% at discharge. Conclusions: CRP appears to be a predictor of future cardiovascular events, confirming that a pro-inflammatory state promotes the progression of atherosclerotic disease and its complications.

Abstract
Atherosclerosis is an inflammatory disease, and several inflammatory biomarkers, such as C-reactive protein, have been used to predict the risk of coronary heart disease. High white blood cell count is a strong and independent predictor of coronary risk in patients of both sexes, with and without coronary heart disease. A high number of white blood cells and their subtypes (for example, neutrophils, monocytes, lymphocytes, and eosinophils) are associated with the presence of coronary heart disease, peripheral arterial disease, and stroke. The coronary heart disease risk ratios associated with a high white blood cell count are comparable to those of other inflammatory markers, including C-reactive protein. In addition, other components of the complete blood count, such as hematocrit and the erythrocyte sedimentation rate, also are associated with coronary heart disease, and the combination of the complete blood count with the white blood cell count can improve our ability to predict coronary heart disease risk. These tests are inexpensive, widely available, and easy to order and interpret. They merit further research.

Abstract
BACKGROUND AND OBJECTIVES Increased risk of mortality in patients with CKD has been attributed to inflammation. However, the association between kidney function, albuminuria, and biomarkers of inflammation has not been examined in a large cohort of CKD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This study measured the plasma levels of IL-1β, IL-1 receptor antagonist (IL-1RA), IL-6, TNF-α, TGF-β, high-sensitivity C-reactive protein (hs-CRP), fibrinogen, and serum albumin in 3939 participants enrolled in the Chronic Renal Insufficiency Cohort study between June 2003 and September 2008. An inflammation score was established based on plasma levels of IL-1β, IL-6, TNF-α, hs-CRP, and fibrinogen. Estimated GFR (eGFR) and serum cystatin C were used as measures of kidney function. Albuminuria was quantitated by urine albumin to creatinine ratio (UACR). RESULTS Plasma levels of IL-1β, IL-1RA, IL-6, TNF-α, hs-CRP, and fibrinogen were higher among participants with lower levels of eGFR. Inflammation score was higher among those with lower eGFR and higher UACR. In regression analysis adjusted for multiple covariates, eGFR, cystatin C, and UACR were strongly associated with fibrinogen, serum albumin, IL-6, and TNF-α. Each unit increase in eGFR, cystatin C, and UACR was associated with a -1.2% (95% confidence interval, -1.4, -1), 64.9% (56.8, 73.3) and 0.6% (0.4, 0.8) change in IL-6, respectively (P<0.001). CONCLUSIONS Biomarkers of inflammation were inversely associated with measures of kidney function and positively with albuminuria.

Abstract
Kidney function declines with age in the majority of the population. Although very few older people progress to end stage, the consequences of doing so are burdensome for the patient and very expensive for the society. Although some of the observed decline is likely due to changes in the vasculature, much is associated with the development of age-associated glomerulosclerosis. This article will review the well-established structural and functional changes in the glomerulus with age. The role of calorie restriction in modifying age-related pathology will be discussed. The importance of the podocyte as a critical cell in the aging process is considered using animal models and human biopsy material. Newer data on changes in gene expression driven by nuclear factor kappa beta (NFkB) and possible changes in biology in the glomerulus are discussed. The relationship between pathways involved in aging and the decline in kidney function is reviewed. There is speculation on the significance of these changes in relation to normal and pathological aging.

Abstract
BACKGROUND To investigate the added value of elevated urinary albumin excretion (UAE) and high high-sensitive C-reactive protein (hs-CRP) in predicting new-onset type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD) and chronic kidney disease (CKD) in addition to the present metabolic syndrome (MetS) defining criteria. METHODS The PREVEND Study is a prospective population-based cohort study in the Netherlands, including 8592 participants. The MetS was defined according to the 2004 International Diabetes Federation criteria, elevated UAE as albuminuria ≥ 30 mg/24 h and high hs-CRP as ≥ 3 mg/L. RESULTS At follow-up, subjects without MetS when compared to subjects with MetS had a lower incidence of T2DM, CVD as well as CKD (2.5 versus 15.5; 4.1 versus 10.3 and 5.8 versus 11.2%, all P < 0.001). In subjects with MetS, the incidence of all three outcomes was higher among subjects with elevated albuminuria versus subjects with normoalbuminuria (all P < 0.01). The incidence of all outcomes was also higher among subjects with high hs-CRP versus subjects without elevated hs-CRP but only significant for CKD (P = 0.002). Multivariate analysis including elevated UAE, hs-CRP and the variables defining the MetS showed that elevated albuminuria was independently associated with the risk for new-onset T2DM, CVD and CKD, whereas high hs-CRP was only independently associated with new-onset CVD and CKD. CONCLUSION Our data show that elevated UAE has added value to the present MetS defining variables in predicting new-onset T2DM, CVD and CKD, whereas hs-CRP adds to predicting new-onset CVD and CKD, but not T2DM.

Abstract
OBJECTIVE Malnutrition is closely linked to chronic kidney disease (CKD) in adult patients with poor outcome. But data on pediatric patients is inadequate. The aim of this study was to describe the prevalence of growth failure and malnutrition in pediatric CKD patients and explore the relationship of these parameters to each other and to other clinical parameters. METHODS This study included 42 patients and 29 healthy children matched for age and gender. Patients were classified firstly in age group and secondly in therapy modalities. Nutritional evaluations were performed according to the Kidney Disease Outcomes Quality Initiative guidelines, and we performed adjustments using values from children with the same chronological age as reference. FINDINGS In pubertal group, the mean height SDS was lower than in pre-pubertal period while it was higher than in early childhood (P=0.4 and P=0.03 respectively). In all groups, 45% of patients had malnutrition: 20 patients on predialysis, 22 patients with end stage renal disease (14 on hemodialysis, and 8 on peritoneal dialysis). The mean weight SDS was lower in end stage renal disease groups (P<0.001). The height SDS was lower in end stage renal disease groups (P<0.001). CONCLUSION Growth failure and malnutrition remain a significant clinical problem as age and therapy modalities are dependent in children with CKD.

Abstract
Cardiovascular morbidity and mortality in patients with chronic kidney disease (CKD) is high, and the presence of CKD worsens outcomes of cardiovascular disease (CVD). CKD is associated with specific risk factors. Emerging evidence indicates that the pathology and manifestation of CVD differ in the presence of CKD. During a clinical update conference convened by the Kidney Disease: Improving Global Outcomes (KDIGO), an international group of experts defined the current state of knowledge and the implications for patient care in important topic areas, including coronary artery disease and myocardial infarction, congestive heart failure, cerebrovascular disease, atrial fibrillation, peripheral arterial disease, and sudden cardiac death. Although optimal strategies for prevention, diagnosis, and management of these complications likely should be modified in the presence of CKD, the evidence base for decision making is limited. Trials targeting CVD in patients with CKD have a large potential to improve outcomes.

Abstract
The epidemics of cardiovascular disease, obesity, diabetes, HIV and cancer have all received much attention from the public, media and policymakers. By contrast, chronic kidney disease (CKD) has remained largely a 'silent' epidemic. This is unfortunate because early diagnosis of renal disease based on proteinuria and/or reduced estimated glomerular filtration rate could enable early intervention to reduce the high risks of cardiovascular events, end-stage renal disease (ESRD) and death that are associated with CKD. Given the global increase in the incidence of the leading causes of CKD--hypertension, obesity and diabetes mellitus--better disease management and prevention planning are needed, as effective strategies are available to slow the progression of CKD and reduce cardiovascular risk. CKD may be regarded as a clinical model of accelerated vascular disease and premature ageing, and the risk-factor profile changes during the progression from mild/moderate CKD to ESRD. Although many randomized controlled trials in patients with mild to moderate CKD have shown beneficial effects of interventions aimed at preventing the progression of CKD, most trials have been unable to demonstrate a beneficial effect of interventions aimed at improving outcome in ESRD. Thus, novel treatment strategies are needed in this high-risk patient group.

Abstract
Evidence is emerging that cognitive impairment, delirium and depression are very common in patients with renal disease. All of these conditions are associated with prolonged hospitalization and an increased risk of mortality. A good understanding of these conditions is key to their prevention, early intervention and management. This Review summarizes the clinical features of various forms of cognitive dysfunction that occur in individuals with renal disease and describes the evidence for the high burden of disease in such patients.

Abstract
Diabetes mellitus (DM) is the leading cause of chronic kidney disease (CKD). Due to an explosion in the incidence and the prevalence of Type 2 DM, the burden of CKD is expected to increase proportionately. Both DM and CKD are associated with a high incidence of cardiovascular (CV) morbidity and mortality, and it is important to understand the unique nature of CV disease in patients with the combination of these two conditions. In this report, we review the traditional and nontraditional risk factors that underlie the high risk of CV disease in this population, with a particular focus on vascular calcification, mineral metabolism, and therapeutic paradigms for the treatment of cardiovascular disease in this unique and high-risk population.

Abstract
Patients with chronic kidney disease have substantial risk for cardiovascular mortality, but the relative importance of traditional and novel risk factors is unknown. Several studies in hemodialysis patients have demonstrated that inflammatory markers are potent predictors of mortality, however there are scarce data about stable patients with moderate chronic kidney disease. 128 outpatients with estimated glomerular filtration of less than 60 ml/min per 1.73 m(2) were included in the study. Medical records about cardiovascular factors were recorded. Analytical parameters and inflammation markers were determined in baseline period. Participants were initially recruited from January 2002 to May 2002. The average length of follow-up in this longitudinal study was 5.5 years. Mortality and non-fatal cardiovascular events were the end points. Median follow-up was 67.8 months, all cause of mortality was 22.7%/(n=29) and non-fatal cardiovascular events were 39.1% (n=50). In multivariate analysis adjusting for demographic, cardiovascular and kidney disease factors, age hazard ratio (HR): 1.01, interval confidence (IC): 1.00-1.10), previous congestive heart failure (HR: 3.50, IC: 1.10-11.17) and both high CRP (HR: 3.48, IC: 1.53-7.59) and serum fibrinogen (HR: 1.45, IC: 1.04-1.50) were independent predictors of all-cause of mortality. Age (HR: 1.06, IC: 1.01-1.11), high CRP (HR: 2.80, IC: 1.60-4.90), cardiac troponin T (HR: 1.21, IC: 1.04-1.40) and previous coronary disease (HR: 2.67, IC: 1.28-5.54) but not serum fibrinogen were independent predictors of non-fatal cardiovascular events. Both high CRP and high serum fibrinogen levels and previous congestive heart failure measured in CKD stages 3 and 4, are independent risk factors for all-cause of mortality. High CRP but not high serum fibrinogen is a risk factor for non-fatal cardiovascular events. These results suggest that high CRP and high serum fibrinogen provide prognostic information in CKD patients.
