As these discoveries came to light, the clinical effectiveness

of FTY720 or fingolimod (Gilenya, Novartis) for the treatment of MS was studied in two large phase III clinical trials involving relapsing-remitting MS patients [48, 49]. Compared with a placebo, fingolimod decreased the annualized relapse rate by 54% [48], and when compared with IFN-β, fingolimod decreased the annualized relapse rate from 0.33 to 0.16 [49]. Thus, in September 2010 fingolimod was approved for use in patients with relapsing forms of MS. It should be noted that two deaths were reported in the trials [48, 49] but in patients taking a higher dose than that which is currently clinically approved. In one of these patients, disseminated primary varicella infection occurred during intravenous steroid treatment for relapse; in the other patient, herpes simplex encephalitis developed, also while the patient was on steroids. Other serious this website reported effects of fingolimod include bradycardia, Lapatinib ic50 a slight increase in lower respiratory tract infections, macular edema, and a reported increase in the development of skin and breast cancers. More recently, as seen with natalizumab, cases of paradoxical worsening of MS [50], or tumefactive MS [51], have been reported after initiation of fingolimod although the cause of these rare events is still unclear. Furthermore there have been more recent reports

of serious herpes infections in patients taking fingolimod at the clinically approved dose [52, 53], reinforcing the need for further surveillance of safety Docetaxel [54]. Thus, patients treated with fingolimod will be followed by a 5-year postauthorization safety study to monitor for adverse events [55]. Although the approval of natalizumab and fingolimod represents the successful targeting of molecules that modulate cell migration, the explosion of knowledge about other cell migration targets, such as the chemokine receptors, has thus far been challenging to translate into new clinical therapeutics. The reasons for these disappointing

results are numerous and have been thoroughly reviewed elsewhere recently [8, 56], but likely include “redundancy” of chemokine function, inadequate in vivo dosing, and the improper selection of targets as was suggested to have occurred in the clinical trials for CCR2 inhibition in rheumatoid arthritis [57]. We believe that an improved understanding of the mechanism and side effects of natalizumab and fingolimod will help address some of these obstacles. For instance, both of these drugs have highlighted the subtleties of modulating lymphocyte trafficking, such as only affecting particular subsets, subtleties that were not fully appreciated prior to their clinical approval. Natalizumab, for instance, has been demonstrated to reduce the number of inflammatory cells in the cerebral spinal fluid of patients with MS, suggesting that it may indeed prevent the access of pathogenic T cells to the brain in humans [58].

After sharing a particular type of referent with an adult in an excited manner, 18-month-olds subsequently found a picture of that type of referent more worthy of Inhibitor Library declarative pointing than some other picture—but only for that adult, not for a different

adult. Mixed results were found with 14-month-olds. We thus show that by 18 months, infants accurately track their shared experiences with specific individuals and use this to make communicative decisions. These results also demonstrate that infants sometimes use declarative pointing to indicate not totally “new” things, as in the classic formulation, but things which are “old” in the sense that “we” should recognize them as similar to something we have previously shared. “
“Collaborative activities in which individuals coordinate their actions to attain a common goal play a fundamental role in our everyday lives. Evidence suggests that infants engage in collaborative activities before their first birthday; however,

little is known about infants’ understanding of collaborative action. Using a visual habituation paradigm, this research consists of two experiments designed to investigate whether 10-month-olds understand that the actions of collaborative partners are critical to the attainment of a common goal. The results of Experiment 1 suggest that 10-month-olds represent the actions of collaborating Acalabrutinib partners in terms of a common collaborative goal only after receiving active experience with a collaborative activity. Experiment 2 demonstrated that infants who received

active experience with a collaborative activity viewed active engagement in a collaboration as being critical for an individual’s actions to be interpreted as being directed towards a collaborative goal. Together, these findings demonstrate that 10-month-olds exhibit an understanding of the shared nature of collaborative goals after a highly salient experience with the activity. Identifying the effects of experience on infants’ understanding of collaborative goals in a laboratory context provides insights into the role that experiences in their everyday lives might play in their understanding of collaboration. “
“We investigated whether Exoribonuclease maternal mind-mindedness in infant–mother interaction related to aspects of obstetric history and infant temperament. Study 1, conducted with a socially diverse sample of 206 eight-month-old infants and their mothers, focused on links between maternal mind-mindedness and (i) planned conception, (ii) perception of pregnancy, and (iii) recollections of first contact with the child. The two indices of mind-mindedness (appropriate and nonattuned mind-related comments) related to different aspects of obstetric history, but no strong associations were seen with socioeconomic status, maternal depression, or perceived social support.

Presented

results showed that C. albicans cells opsonization with sera significantly improved the killing efficiency of PMN. The ability of immune sera prepared by immunization with M5-BSA conjugate to induced PMN’s killing activity was comparable to or statistically significantly lower (3rd sc dose) than capacity of placebo control sera. The lower efficiency of immune sera to induce candidacidal activity is probably related with lower capacity of specific antibodies buy GPCR Compound Library to recognize corresponding antigenic structures in cell wall of C. albicans cells and to activate complement, which leads to limited opsonization and reduced induction of PMN’s candidacidal activity. Sera obtained by immunization with M6-BSA conjugate slightly improved the candidacidal activity of PMN with statistically significantly higher effect than control sera for sera after the 1st and the 3rd sc dose Ulixertinib of conjugate. Comparison of obtained results revealed different functionality of antibodies induced by these two conjugates containing structurally similar α-1,6-branched oligomannosides. Mannan is also able to contribute to the resistance of C. albicans to complement activation through the alternative pathway in the absence of mannan-specific

antibodies [36]. Han and Cutler described protection by a murine IgM and IgG3 antibodies requiring an intact complement system in a mouse model of disseminated candidiasis [6]. We observed mainly decrease in PMN’s candidacidal activity using complement-inactivated sera in comparison with non-inactivated sera; thus, inactivation of complement in sera obtained by immunization with conjugates mainly reduced effectiveness of sera to induce candidacidal activity (Fig. 6). Upon obtained results, we assume different specificity and different

potential protective efficacy of antibodies induced by immunization with M5-BSA and M6-BSA conjugates. The importance of antibodies specificity seems to be critical for induction of candidacidal activity and obtained result confirmed low correlation between protection and mannan or whole cell–specific antibodies levels alone [13, 14]. In addition, results 2-hydroxyphytanoyl-CoA lyase obtained with M5-BSA and M6-BSA conjugates revealed lower ability of α-1,6-branched oligomannoside – BSA conjugates in comparison with linear oligomannoside – BSA conjugates to induce production of antibodies with strong reactivity to corresponding antigenic determinants in natural cell wall mannan and lower capacity to induce antibodies significantly enhancing candidacidal activity of PMN in comparison with previously published results obtained with linear oligomannoside – BSA conjugates [13, 14].

“Meningeal melanocytoma is an uncommon pigmented neoplasm that affects the CNS and develops in the cranial and spinal leptomeninges. Here we report on a case of malignant transformation of intracranial supratentorial meningeal melanocytoma which recurred after 3 years as malignant melanoma. This case demonstrates that the biological behavior of melanocytoma LY294002 nmr is uncertain and that these lesions may recur as malignant melanoma. “
“Human genetic Creutzfeldt-Jakob disease (gCJD; one

of the prion diseases) is caused by point mutations and insertions in the prion protein gene (PRNP). Previously we have reported a Chinese gCJD case with a substitution of valine (V) for glycine (G) at codon 114. To investigate the detailed pathogenic and pathologic characteristics of G114V gCJD, 10 different brain regions were thoroughly analyzed. PrP-specific Western blots and immunohistochemical (IHC) assays identified

larger amounts of PrPSc in the regions of brain cortex. Assays of the transcriptions of PrP-specific mRNA by RT-PCR and real-time PCR showed comparable levels in 10 brain regions. In line with the distribution of PrPSc, typical vacuolations in brains, markedly in four cortex regions, were detected. Contrast to the distributing features of spongiform and of PrPSc, massive gliosis was detected in all brain regions by GFAP-specific IHC tests. Moreover, two-dimensional gel immunoblots found three major sets of PrPSc spots, indicating that PrPSc in brain tissues was a mixture of molecules Cobimetinib research buy with different biochemical very properties. The data here provide the pathogenic and neuropathological features of G114V gCJD. “
“P. N. Harter, B. Bunz, K. Dietz, K. Hoffmann, R. Meyermann and M. Mittelbronn (2010) Neuropathology and Applied Neurobiology36, 623–635 Spatio-temporal deleted in colorectal cancer (DCC) and netrin-1 expression in human foetal brain development

Aims: Deleted in colorectal cancer (DCC) and its ligand netrin-1 are known as axonal guidance factors, being involved in angiogenesis, migration and survival of precursor cells in the embryonic mammalian central nervous system (CNS). So far, little is known about the distribution of those molecules in human CNS development. Methods: We investigated 22 human foetal brain specimens (12th and 28th week of gestation) for DCC and netrin-1 expression by means of immunohistochemistry, immunofluorescence and confocal laser microscopy. Statistical analysis was performed by applying a semi-quantitative score, including staining intensity and frequency and correlation with foetal age. Results: DCC and netrin-1 were differentially expressed throughout the developing human foetal telencephalic and cerebellar cortical layers. Netrin-1 exhibited the highest levels in telencephalic germinal layers, whereas the strongest DCC immunoreactivity was seen in the developing cortical plate. Netrin-1 and DCC were predominantly present on cerebellar external granule layer cells.

5B and C). Supporting this model is the marked increase in the ratio of FoxP3+Tregs to T effectors detected in the PaLN and islets of NOD.B6Idd3 mice relative to age-matched

NOD female mice (Fig. 5A). In addition, CD4+CD25+ T cells from the PaLN of NOD.B6Idd3 mice proved to be more effective at suppressing the adoptive transfer of diabetes relative to NOD CD4+CD25+ T cells (Fig. 5C). One caveat with the latter finding is that, despite similar Sirolimus nmr numbers of activated T effectors (e.g. FoxP3-CD4+CD25+ T cells) in the transferred NOD and NOD.B6Idd3 CD4+CD25+ T cells, an increased frequency of β-cell-specific pathogenic effector T cells may have limited the efficacy the NOD Tregs pool. A previous study, however, showed that proliferation

of transferred diabetogenic CD4+ T cells was significantly reduced in the PaLN of NOD.B6Idd3 versus NOD recipients 38, which is consistent with NOD.B6Idd3 mice having enhanced suppressor activity. Noteworthy is that no difference was detected in the in vitro suppressor activity of CD62LhiFoxP3+Tregs from NOD and NOD.B6Idd3 mice (Fig. 4C); in addition, similar in vivo suppressor activity was detected for the respective CD62LhiFoxP3+Tregs as determined by co-adoptive transfer experiments (M. C. J. and R. T.; unpublished data). These observations argue that quantitative and not qualitative differences in CD62LhiFoxP3+Tregs explain the distinct suppressor C59 wnt purchase activity of the FoxP3+Tregs pool detected in NOD and NOD.B6Idd3 mice (Fig. 5B). It is important to note that the frequency of CD62LhiFoxP3+Tregs decreased with age in the islets of NOD.B6Idd3 albeit to a lesser extent than seen in NOD islets (Fig. 3D). NOD.B6Idd3 mice develop insulitis and diabetes but at a reduced frequency and a delayed onset compared with NOD mice (Fig. 1). Therefore, in addition to IL-2, other factors contribute to the homeostasis and function

of CD62LhiFoxP3+Tregs. In summary, we demonstrate that reduced IL-2 expression impacts FoxP3+Tregs in NOD mice by altering the ratio of CD62Lhi to CD62Llo FoxP3+Tregs and in turn reducing the suppressor activity of the FoxP3+Tregs compartment. These findings provide further rationale for the development of IL-2-based immunotherapy as a means to manipulate FoxP3+Tregs for the prevention and suppression of β-cell autoimmunity. Interleukin-2 receptor NOD/LtJ and NOD.CB17-Prkdcscid/J (NOD.scid) mice were maintained and bred under pathogen-free conditions in an American Association for Laboratory accredited animal facility. NOD.B6c3D mice, provided by Dr. Ed Leiter (The Jackson Laboratory), C57BL/6 were established by introgression of an ∼17 Mb region of the Idd3 interval derived from C57BL/6 mice (NOD.B6Idd3) for 13 backcross generations. The length of the congenic interval was determined by typing with MIT microsatellite markers and using the MGI posting data from NCBI Build 37 (Supporting Information Table. 1). Mice were monitored for diabetes by measuring urine glucose levels.

trachomatis released from NK cell-exposed infected cells, pooled A2EN cell lysates and culture supernatants from C. trachomatis-infected cells cocultured with NK cells were compared with those cultured for the same period of time postinfection but in the absence of NK cells. The marked decrease in recoverable IFU from cells cocultured with NK92MI cells (Fig. 5; Fig. S1) suggests that these effector cells exert some degree of sterilizing effect on C. trachomatis-infected endocervical cells and that host NK cells could decrease the infectious burden during C. trachomatis infection. Surprisingly, however, we note that although efficient lysis of C. trachomatis-infected cells was observed

at 34 hpi, the observed decrease in IFU recovered was only twofold. These data suggest that C. trachomatis may be equipped with some form of escape mechanisms despite NK cell-mediated Lumacaftor cost lysis of its host cells. Infectious pathogens evade innate and adaptive host immune detection through modulation of host responses. Successful pathogens, including C. trachomatis, exert overlapping and redundant mechanisms that often include alterations in those host ligands that mediate interactions with innate and adaptive immune cells (Tortorella et al., 2000). While Selleckchem HSP inhibitor well-orchestrated, pathogen protective strategies would promote evasion of antigen nonspecific innate immunity and antigen-specific adaptive

responses, co-evolution of pathogen and host enable a balance between Sorafenib mouse pathogen evasion

and host protection. For C. trachomatis, we and others have shown that host cell MHC class I, Class II, and CD1d are degraded in infected cells relatively late in the pathogen’s developmental cycle (Zhong et al., 1999; : Zhong et al., 2000; : Zhong et al., 2001; Kawana et al., 2007, 2008). This occurs well after the initiation of chemokine/cytokine secretion by C. trachomatis-infected epithelial cells, which usually does not begin until 20–24 h after infection (Rasmussen et al., 1997). The latter delay may allow a window for unfettered pathogen growth and development. We have recently demonstrated that downregulation of cell surface expression of MHC class I in C. trachomatis-infected A2EN cells can be seen on infected cells and on bystander, noninfected cells in culture (Ibana et al., 2011a), which may further protect C. trachomatis pathogens from antigen-specific clearance. By harnessing our capability to assess the host epithelial cell response to C. trachomatis in both bystander-noninfected cells and C. trachomatis-infected cells, we now show that the effects on MHC class I and on MICA kinetically occur in tandem, beginning prior to 24 hpi and lasting until late in the developmental cycle. Unlike its effects on MHC class I, the effects of C. trachomatis on MICA expression include an upregulation of expression, effects that are significantly more prolonged (still rising at 42 hpi) and effects that are limited to infected cells.

1), in which S1PR5 plays a role in BM egress [16]. To investigate the function of S1PR5 in monocytes, we first compared the percentage of

monocyte subsets in the blood of wild-type (WT) and S1pr5−/− mice [18] by flow cytometry. Results in Figure 2A–C showed a significant reduction of Ly6C− monocytes in the blood of S1pr5−/− mice. This reduction was observed both in S1pr5−/− female (Fig. 2A and B) and male mice (Fig. 2C). S1pr5+/− heterozygous mice also showed a mild phenotype (Fig. 2B). A strong reduction in the frequency Fulvestrant concentration of Ly6C− monocytes was also observed in the spleen, which is known to be an important reservoir for this subset [19] (Fig. 2D), in the lymph nodes and in non-lymphoid organs such as the lung, liver, and kidney (Fig. 2E). By contrast, the percentage of Ly6C− monocytes appeared normal in the BM of S1pr5−/− mice (Fig. 2F). Moreover, the percentage of Ly6C+ monocytes was normal in

all lymphoid organs of S1pr5−/− mice tested (Fig. 2, all panels). To test if the role of S1PR5 in monocytes was cell-intrinsic, we generated mixed BM chimeras by reconstituting lethally irradiated mice with equal amounts of BM from WT (CD45.1+) and S1pr5−/− (CD45.2+) mice. Six weeks after reconstitution, we measured CD45.1 and CD45.2 expression in different immune subsets in the blood and BM, and calculated the corresponding S1pr5−/− to WT ratio for each subset. As previously reported [20], for selleck screening library mature NK (mNK) cells, this ratio was very high in the BM and very low in the blood (Fig. 3, left panel), reflecting the important role of S1PR5 in NK cell exit from the BM. For Ly6C+ monocytes, the S1pr5−/− to WT ratio was

nearly 1 in both blood and BM (Fig. 3, right panel), confirming the absence of a role of S1PR5 in this subset. By contrast, for Ly6C− monocytes, the S1pr5−/− to WT ratio was near 0.5 in the BM and 0.1 in the blood (Fig. 3, left panel). These data suggest that S1PR5 is important both for the development of Ly6C− monocytes and for their trafficking or their survival Methamphetamine at the periphery. The paucity of patrolling monocytes in the periphery of S1pr5−/− mice could be explained by a role of this receptor either in their egress from the BM or in their survival at the periphery. To try and discriminate between both hypotheses, we performed a series of experiments using Cx3Cr1gfp/gfp and Ccr2−/− mice as controls. Indeed, CX3CR1 has been shown to regulate peripheral survival of patrolling monocytes but is devoid of chemotactic activity involved in BM egress. Reciprocally, CCR2 is essential for monocyte egress from the BM but is not involved in their survival. The distribution of Ly6C− monocytes in Cx3cr1gfp/gfp and Ccr2−/− mice is in fact very similar to that of S1pr5−/− mice, with a near normal frequency in the BM and a low frequency of these cells at the periphery (Fig. 4A).

To assess responses

to GAD65 epitopes that could be processed and presented from intact protein, CD4+ T cells were primed by stimulation with GAD65 protein and then screened using tetramers loaded with each of the antigenic peptides identified by tetramer-guided epitope mapping. Briefly, 2·5 × 106 ‘no-touch’ Microbead-enriched CD4+ T cells were stimulated with 1·2 × 105 GAD65 protein loaded monocytes in one well of a 48-well plate. CD14+ monocytes were isolated and pulsed with recombinant GAD65 protein as in the protein-stimulated proliferation assays. At least four replicate wells (of a 48-well plate) were set up for each subject. The T cells were cultured for 14 days, adding fresh media and interleukin-2

as needed starting on day 7. Expanded cells were stained learn more with HLA-DR0401 tetramers loaded with each antigenic buy BAY 57-1293 GAD65 peptide. Again, tetramer responses were considered positive when distinct staining that was more than twofold above background (this was set to 0·2% and subtracted) was observed. As described in the Materials and methods section, the tetramer-guided epitope mapping approach was used to comprehensively investigate DR0401-restricted epitopes within GAD65. Peptide pools spanning the entire GAD65 sequence were used to stimulate CD25-depleted T cells from multiple donors with DR0401 haplotypes. Consistent with the representative results shown in Fig. 1(a), a total of 17 different peptides (from 11 peptide pools) elicited a positive response from at least one of the subjects tested. With the exception of pool #6, the antigenic peptides

within each of these peptide pools could be identified using tetramers loaded with individual peptides. The antigenic peptide from pool #6 could not be identified using this approach. However, peptide p26 (GAD201–220) from pool #6 was identified as the antigenic peptide by means of a proliferation assay (Fig. 1b) and was further confirmed by stimulating Ribonucleotide reductase of CD4+ T cells with the individual GAD201–220 peptide and staining with the DR0401/GAD#6 pooled tetramer (data not shown). The peptide sequences containing these epitopes are summarized in Table 1. The 17 antigenic peptides identified included five pairs of adjacent, overlapping peptides. It seemed likely that some of these adjacent overlapping peptides contain a single, shared antigenic sequence. To delineate the antigenic sequences within these adjacent overlapping peptides, we generated tetramer-positive T-cell lines for at least one peptide from each pair. As shown in Fig. 2, we assessed the proliferation of these lines in response to each of the adjacent peptides. These results suggested that three pairs of overlapping peptides (GAD105–124 and GAD113–132, GAD265–284 and GAD273–292, GAD545–564 and GAD553–572) appear to contain distinct antigenic sequences, because T-cell lines only proliferated in response to one of the peptides.

To assess the role of bacterial and viral stimuli in Th2 differentiation, CD4+ T cells from cord blood were assayed in an MLR together with different strains of bacteria and virus. To compare the effect of the different microbes on cytokine secretion, we assessed the relative change in cytokine production for each microbe. The relative change was calculated using the amount of cytokine produced in MLR cultures containing a specific microbe, divided by the cytokine amount secreted in an MLR lacking microbe. All enveloped viruses tested (coronavirus, CMV, HSV-1, influenza virus and morbillivirus)

downregulated the IL-13 responses in cord blood cocultures (Fig. 3E,F). The non-enveloped Doxorubicin ic50 viruses, adenovirus and poliovirus had no effect on the IL-13 production in cord MLR cultures using either pDC (Fig. 3F) or mDC (Fig. 3E) from cord blood as antigen presenting cells. Neither did any of the bacteria reduce the IL-13 responses. Instead, S. aureus stimulated pDC increased the IL-13 production in responding CD4+ cord T cells (Fig. 4F). We were not able to document any significant inhibitory effects on the IL-5 production by the virus, most likely due to the very low initial production selleck screening library of this

cytokine (not shown). The effect of viral and bacterial stimuli on Th1 cytokine secretion was assessed using cord CD4+ T cells cocultured with allogenic pDC or mDC from cord blood. Both bacteria and virus could affect IL-2 and IFN-γ secretion by cord CD4+ T cells (Figs 3 and 4). Influenza virus was the most Bacterial neuraminidase efficient inducer of IL-2 and significantly enhanced the responses in cord CD4+ T cells exposed to cord pDC (Fig. 3B) and to cord mDC (Fig. 3A). Influenza virus also enhanced the IFN-γ responses, but only in cord T cell/mDC cultures (Fig. 3C). None of the other viruses tested affected the IL-2 or IFN-γ production in these cocultures except CMV that reduced the IL-2 production from cord CD4+ T cells and pDC cocultures (Fig. 3B), that is from the

cells with the highest initial IL-2 production (Fig. 2A). Staphlococcus aureus was the only bacteria that enhanced IL-2 responses by cord CD4+ T cells exposed to both mDC (Fig. 4A) and pDC (Fig. 4B). Staphlococcus aureus was also a potent inducer of IFN-γ responses in both pDC and mDC stimulated cord CD4+ T cells (Fig. 4C,D). To assess innate cytokine secretion in cord DC, pDC and mDC from cord blood were stimulated with different strains of bacteria and virus together with allogenic cord CD4+ T cells. We found that all Gram-positive bacteria, but not E. coli or any of the viruses, promoted an IL-12 p40 response in MLR cultures with mDC (Fig. 5A,C) but not with pDC (not shown). The increase in IL-12 production in C. difficile stimulated cell cultures was, however, not statistically significant, even though there was a strong trend (Fig. 5A). We also analysed the ability of virus and bacteria in evoking an IFN-α response in pDC.

Conclusion: C.E.R.A. was useful for renal anemia treatment. Hb variability of C.E.R.A. and its effect for prognosis was similar with that of epoetin beta. CHOI SU JIN, KIM YOUNG SOO, YOON SUN AE, KIM YOUNG OK Uijeongbu St. Mary’s Hospital Introduction: We have reported that arterial micro-calcification (AMC) of vascular access has a negative impact on access patency and cardiovascular

mortality in hemodialysis (HD) patients. Reasons behind increased cardiovascular mortality in AMC are not fully understood, but it is believed that aortic stiffness is a major contributing factor. Whereas, coronary artery calcification (CAC) is quite common in HD patients and it is known as predictor of future cardiovascular events and all cause

mortality in HD patients. The aim of this study was to explore the relationship between AMC and CAC in HD patients. Methods: We check details have reported selleck compound that arterial micro-calcification (AMC) of vascular access has a negative impact on access patency and cardiovascular mortality in hemodialysis (HD) patients. Reasons behind increased cardiovascular mortality in AMC are not fully understood, but it is believed that aortic stiffness is a major contributing factor. Whereas, coronary artery calcification (CAC) is quite common in HD patients and it is known as predictor of future cardiovascular events and all cause mortality in HD patients. The aim of this study was to explore the relationship between AMC and CAC in HD patients. Results: Mean age was 65.8 ± 12.5 years and the male gender was 37 (57.8%). The incidence of AMC was 62.5% (n = 40). The mean CACS was 439.3 ± 901.1 (0–5674.1), and the median value was 128.4. Patients with the positive AMC group showed a significantly older age (68.6 ± 10.2 vs 61.2 ± 14.7, p = 0.036) and a higher prevalence of diabetes (85.0% vs 45.8%, p = 0.001). Positive AMC group showed high incidence of high CACS compared to negative AMC group (77.5% vs 20.8%, p = 0.000). By binary logistic regression, high CACS was independently associated with positive AMC (OR 8.894, 95% CI 1.174–46.154, p = 0.008). Conclusion: The

present study suggests that AMC is closely associated with CACS in HD patients.
