    Conclusions. Higher levels of IL-18 are detected in active AODS patients and correlate with disease activity and inflammatory laboratory features. ROC-AUC analysis of the serum concentration of IL-18 suggests that it can be considered a diagnostic marker of AOSD. This paper supports the targeting of this cytokine as a possible therapeutic option in AOSD.

    The complex picture of inflammation and coagulation alterations comes to life in acute stroke phases. Increasing evidence points to a strong interaction and extensive crosstalk between the inflammation and coagulation systems: the interest towards this relationship has increased since recent experimental research showed that the early administration of antithrombin III (ATIII) decreases the volume of ischemia in mice and might be neuroprotective, playing an antiinflammatory role. We aimed to establish the extent of the relationship among markers of inflammation (S100B and IL-18) and procoagulant and fibrinolytic markers (ATIII, thrombin-antithrombin III complex (TAT), Fibrin Degradation Products (FDP), D-dimer) in 13 comatose patients affected by focal cerebral ischemia. Plasma levels of TAT, D-dimer and FDP, IL18 and S100B were increased. IL-18 and S100B high serum levels in ischemic patients suggest an early activation of the inflammatory cascade in acute ischemic injury. The basic principles of the interaction between inflammatory and coagulation systems are revised, from the perspective that simultaneous modulation of both coagulation and inflammation, rather than specific therapies aimed at one of these systems could be more successful in stroke therapy.

    Full Text Available Studies about the role of cytokines on the immunopathogenesis of atopic dermatitis (AD are generally based on in vitro observations and this role has not been completely clarified yet. Serum levels of total IgE, IL-18, IL-12, IFN- γ and the relationship between these parameters and disease severity, determined using the SCORAD index, in a group of atopic patients were investigated in this study. Serum levels of total IgE were measured by the nephelometric method and serum levels of IL-18, IL-12/p40 and IFN- γ were measured by ELISA method. Serum levels of total IgE and IL-18 were found significantly higher in study group than in controls ( p<.001 . There was no statistically significant difference between patients and controls in respect of serum levels of IL-12/p40 ( p=.227 . A statistically significant relationship between SCORAD values and serum levels of total IgE ( p<.001 , IL-18 ( p<.001 , and IL-12/p40 ( p<.001 was determined. These results show that serum levels of IL-18 can be a sensitive parameter that importantly correlates with clinical severity of AD, can play a role in the immunopathogenesis of AD, and furthermore may be used in the diagnosis and follow-up of the disease in addition to other parameters.

    Full Text Available Microvascular abnormalities are one of the most important causes of persistent diabetic complications. The aim of this study was to compare microvascular changes examined by nailfold capillaroscopy with serum concentrations of soluble E-selectin (sE-selectin and IL-18 in type 1 diabetic patients with and without microangiopathy. Serum levels of sE-selectin and IL-18 were determined by an enzyme-linked immunosorbent assay in 106 patients with type 1 diabetes and in 40 healthy controls. All diabetic patients were evaluated by extensive clinical, laboratory and capillaroscopic studies. Morphological changes were observed by nailfold capillaroscopy in 86 out of 106 (81% diabetic patients. Severe capillaroscopic changes were seen in 32 out of 54 (59% patients with microangiopathy, but in only seven out of 52 (13% patients without microangiopathy. Higher serum levels of sE-selectin (p < 0.001 and IL-18 (p < 0.05 were demonstrated in diabetic patients compared to controls. Significant differences of sE-selectin (p < 0.001 and IL-18 (p < 0.01 serum concentrations were observed between diabetic patients with microangiopathy and controls. Moreover, comparison between patients with and without microangiopathic complications showed a significantly higher capillaroscopic score and sE-selectin serum concentration in the group with microangiopathy (p < 0.001. Furthermore, diabetic patients with severe microvascular changes in capillaroscopy showed significantly higher IL-18 (p < 0.001 and sE-selectin (p < 0.05 serum levels than subgroups without changes or with mild abnormalities. Our findings suggest that abnormalities in nailfold capillaroscopy may reflect the extent of microvascular involvement and are associated with higher sE-selectin and IL-18 serum levels, as well as with microangiopathic complications in diabetic patients.

    Full Text Available Abstract Background The pleiotropic pro-inflammatory cytokine Interleukin (IL-18 has been proposed to play a role in schizophrenia, since elevated circulating levels of its protein and altered frequencies of genetic variants in its molecular system are reported in schizophrenic patients. Methods We analyzed 77 patients with schizophrenia diagnosis (SCZ and 77 healthy control subjects (HC for serum concentration of both IL-18 and its natural inhibitor, the IL-18 binding protein (IL-18BP. Results We confirmed that serum levels of total IL-18 are significantly increased in SCZ, as compared to HC. However, due to a highly significant increase in levels of circulating IL-18BP in SCZ, as compared to HC, the levels of free, bioactive IL-18 are not significantly different between the two groups. In addition, the relationships between the levels of IL-18 and its inhibitor, as well as between the two molecules and age appear dissimilar for SCZ and HC. In particular, the elevated levels of IL-18BP, likely a consequence of the body’s attempt to counteract the early prominent inflammation which characterizes schizophrenia, are maintained in earlier and later stages of the disease. However, the IL-18BP elevation appears ineffective to balance the IL-18 system in younger SCZ patients, while in older patients the levels of circulating bioactive IL-18 are comparable to those of HC, if not lower. Conclusions In conclusion, these findings indicate that the IL-18 system is perturbed in schizophrenia, supporting the idea that this pro-inflammatory cytokine might be part of a pathway of genetic and environmental components for vulnerability to the disease.

    Full Text Available Bacground/Aim. Experimental in vitro and in vivo investigations in a mouse model have proved that TNF-alpha, IL-12, IL- 15 and IL-18 participate in the pathogenesis of erosive inflammatory arthritis. The aim of this research was to determine the clinical significance of cytokines in the evaluation of the activity of rheumatoid arthritis (RA. Methods. Inside a 4-year period we followed-up 64 patients with RA as newly occurred or in the phase of worsening. We observed the clinical manifestation of the disease upon wluch we divided the patients in to 3 groups: the patients with low active RA, patients with moderate active RA, and the patients with wild active RA. The control group (n = 25 patients included the patients with osteoarthrosis (OA, and arthritis of the knee. In the samples of serum of all of the patients the concentrating of cytokines TNF-alpha, IL-12, IL-15, and IL-18 were determined using the immunoenzymatic methods in mice for human interleukines. By comparing the concentrations in 30 patients with the high, 14 patients with moderate, and 20 patients with the mild activity of RA it was determined that the patients with the high degree of the disease activity, had significantly high (p < 0.01; p < 0.05 concentrations of the examined cytokines in blood and synovial fluid as compared to the patients with the moderate and mild active disease. There was a relationship (p < 0.01 between the concentrations of cytokines in blood and synovial fluid with the quantity of the Disease Activity Score in 28 joints. Conclusions. Cytokines concentrations could be good indicators of the degree of the general activity of RA. This research could contribute to the interpretation of insufficiently well known views of the pathogenesis role and significance of citokines in an active disease.

    Full Text Available Proinflammatory cytokine IL-18 has been shown to be elevated in the sera of ovarian carcinoma patients. The aim of the study was to examine the levels and cellular origin of IL-18, IL-18 binding protein, and IL-18 receptor in normal and cancerous ovarian tissues. Ovarian tissue samples were examined by immunohistochemical staining for IL-18, IL-18BP, and IL-18R and mRNA of these cytokines was analyzed with semiquantitative PT-PCR. IL-18 levels were significantly higher in cancerous ovarian tissues (P=0.0007, IL-18BP levels were significantly higher in normal ovarian tissues (P=0.04, and the ratio of IL-18/IL-18BP was significantly higher in cancerous ovarian tissues (P=0.036. Cancerous ovarian tissues expressed significantly higher IL-18 mRNA levels (P=0.025, while there was no difference in the expression of IL-18BP mRNA and IL-18R mRNA between cancerous and normal ovarian tissues. IL-18 and IL-18BP were expressed dominantly in the epithelial cells of both cancerous and normal ovarian tissues, while IL-18R was expressed dominantly in the epithelial cells of cancerous ovarian tissues but expressed similarly in the epithelial and stromal cells of normal cancerous tissues. This study indicates a possible role of IL-18, IL-18BP, and IL-18R in the pathogenesis of epithelial ovarian carcinoma.

    The inflammasome is a cytoplasmic multiprotein complex that promotes proinflammatory cytokine maturation in response to host- and pathogen-derived signals. Missense mutations in cryopyrin (NLRP3) result in a hyperactive inflammasome that drives overproduction of the proinflammatory cytokines IL-1β and IL-18, leading to the cryopyrin-associated periodic syndromes (CAPS) disease spectrum. Mouse lines harboring CAPS-associated mutations in Nlrp3 have elevated levels of IL-1β and IL-18 and closely mimic human disease. To examine the role of inflammasome-driven IL-18 in murine CAPS, we bred Nlrp3 mutations onto an Il18r-null background. Deletion of Il18r resulted in partial phenotypic rescue that abolished skin and visceral disease in young mice and normalized serum cytokines to a greater extent than breeding to Il1r-null mice. Significant systemic inflammation developed in aging Nlrp3 mutant Il18r-null mice, indicating that IL-1 and IL-18 drive pathology at different stages of the disease process. Ongoing inflammation in double-cytokine knockout CAPS mice implicated a role for caspase-1-mediated pyroptosis and confirmed that CAPS is inflammasome dependent. Our results have important implications for patients with CAPS and residual disease, emphasizing the need to explore other NLRP3-mediated pathways and the potential for inflammasome-targeted therapy.

  4. Correlation of IL-18 with Tryptase in Atopic Asthma and Induction of Mast Cell Accumulation by IL-18

    2016-01-01

    Full Text Available Interleukin- (IL- 18 and tryptase were previously reported to relate to asthma, but the correlation between these two potent proinflammatory molecules in asthma and their roles in mast cell accumulation remain uninvestigated. Using flow cytometric analysis technique and ovalbumin- (OVA- sensitized mouse model, it was found that IL-18 and tryptase levels in the plasma of moderate and severe asthma were elevated, and they correlated well with each other. Tryptase and agonist peptides of protease activated receptor- (PAR- 2 induced substantial quantity of IL-18 release. IL-18 and tryptase provoked mast cell accumulation in peritoneum of OVA-sensitized mice. OVA-sensitization increased number of IL-18 receptor (R+ mast cells. IL-18 and tryptase induced dramatic increase in IL-18R+ mast cells and mean fluorescence intensity (MFI of IL-18R on mast cells. Moreover, while IL-18 induced an increase in PAR-2+ mast cells in nonsensitized mice, IL-18 and tryptase provoked increases in IL-4 and thymic stromal lymphopoietin (TSLP in the peritoneum of OVA-sensitized mice. In summary, the correlation between IL-18 and tryptase in plasma of patients with asthma indicates close interactions between them, which should be considered for development of anti-IL-18 and antitryptase therapies. Interactions between IL-18 and tryptase may contribute to mast cell recruitment in asthma.

    Interleukin 18 (IL-18) plays an important role in the T-helper-cell type 1 immune response against intracellular parasites, bacteria and viral infections. It has been widely used as an adjuvant for vaccines and as an anticancer agent. However, IL-18 protein lacks a typical signal sequence and requires cleavage into its mature active form by caspase 1. In this study, we constructed mammalian expression vectors carrying cDNA encoding mature canine IL-18 (cIL-18) or mouse IL-18 (mIL-18) fused to the human IL-2 (hIL-2) signal sequence. The expressed proIL-18 proteins were processed to their mature forms in the cells. The supernatants of cells transfected with these plasmids induced high interferon-γ production in canine peripheral blood mononuclear cells or mouse splenocytes, respectively, indicating the secretion of bioactive IL-18. Using reverse genetics, we also generated a recombinant canine distemper virus that expresses cIL-18 or mIL-18 fused to the hIL-2 signal sequence. As expected, both recombinant viruses produced mature IL-18 in the infected cells, which secreted bioactive IL-18. These results indicate that the signal sequence from hIL-2 is suitable for the secretion of mature IL-18. These recombinant viruses can also potentially be used as immunoadjuvants and agents for anticancer therapies in vivo.

  6. TWEAK appears as a modulator of endometrial IL-18 related cytotoxic activity of uterine natural killers.

    Directory of Open Access Journals (Sweden)

    Marie Petitbarat

    Full Text Available BACKGROUND: TWEAK (Tumor necrosis factor like WEAK inducer of apoptosis is highly expressed by different immune cells and triggers multiple cellular responses, including control of angiogenesis. Our objective was to investigate its role in the human endometrium during the implantation window, using an ex-vivo endometrial microhistoculture model. Indeed, previous results suggested that basic TWEAK expression influences the IL-18 related uNK recruitment and local cytotoxicity. METHODOLOGY/PRINCIPAL FINDINGS: Endometrial biopsies were performed 7 to 9 days after the ovulation surge of women in monitored natural cycles. Biopsies were cut in micro-pieces and cultured on collagen sponge with appropriate medium. Morphology, functionality and cell death were analysed at different time of the culture. We used this ex vivo model to study mRNA expressions of NKp46 (a uNK cytotoxic receptor and TGF-beta1 (protein which regulates uNK cytokine production after adjunction of excess of recombinant IL-18 and either recombinant TWEAK or its antibody. NKp46 protein expression was also detailed by immunohistochemistry in selected patients with high basic mRNA level of IL-18 and either low or high mRNA level of TWEAK. The NKp46 immunostaining was stronger in patients with an IL-18 over-expression and a low TWEAK expression, when compared with patients with both IL-18 and TWEAK high expressions. We did not observe any difference for TWEAK expression when recombinant protein IL-18 or its antibody was added, or conversely, for IL-18 expression when TWEAK or its antibody was added in the culture medium. In a pro-inflammatory environment (obtained by an excess of IL-18, inhibition of TWEAK was able to increase significantly NKp46 and TGF-beta1 mRNA expressions. CONCLUSIONS/SIGNIFICANCE: TWEAK doesn't act on IL-18 expression but seems to control IL-18 related cytotoxicity on uNK cells when IL-18 is over-expressed. Thus, TWEAK appears as a crucial physiological modulator

    Background We specifically designed this study to determine the relationship between levels of IL-8 and carotid intima-media thickness (cIMT) in patients with type 2 diabetes mellitus (T2DM). Material/Methods A total of 149 diabetic patients at different stages of diabetic nephropathy and 72 matched controls were recruited in this study. A wide range of parameters were measured: IL-18 (by ELISA), urinary albumin excretion rates (UAER), and carotid intima-media thickness (cIMT, by pulse wave velocity [PWV]). All the diabetic patients were treated by alprostadil. Results ELISA indicated that the level of IL-18 in the patient group was significantly higher compared with that in the control group. The level of IL-18 apparently increased in the higher cIMT group in T2DM patients. Serum IL-18 levels were positively correlated with cIMT in patients with T2DM, the level of IL-18 was negatively correlated with cIMT, and IL-18 levels were positively correlated to age. Moreover, IMT was positively correlated with hemoglobin A1C (HbA1C) and IL-18 levels were significantly associated with cIMT (all P<0.05). Conclusions IL-18 levels were positively correlated with atherosclerotic burden in patients with T2DM and it may be considered as a significant therapeutic target. PMID:28125566

    Cytokines present in the reproductive system play an important role both in the modulation of immune responses to infectious challenge and in the establishment and maintenance of pregnancy. Interleukin 18 (IL-18) has been regarded as an important regulator of innate and acquired immune response, but its expression and distribution in the hypothalamic-pituitary-ovarian axis remain unclear. In this paper, the expression and distribution of IL-18 in non-pregnant, pregnant, and early abortive rats were examined using an ultra-sensitive immunohistochemical streptavidin-peroxidase method, enzyme-linked immunosorbent assay, and reverse transcription-polymerase chain reaction. The results showed that IL-18 expression in the pituitary, in follicular ovaries, and in the corpus luteum of abortive rats were significantly lower than that of pregnant and non-pregnant rats. However, the staining of IL-18 in the hypothalamus, interstitial glands of the ovary, and uterus of abortive rats was strikingly stronger than those of the non-pregnant ones. IL-18 mRNA expression in rat uterus was detected in all groups, whereas IL-18 mRNA content in abortive rat uterus was significantly higher than in normal pregnant rats. Further, IL-18 in the peripheral blood serum of abortive rats was significantly lower than in same-period normal pregnant rats. The differential expression of IL-18 in early abortion suggests that IL-18 may be related to the underlying mechanisms of abortion.

    Variation within the gene for the proinflammatory cytokine interleukin (IL)-18 has been associated with inter-individual differences in levels of free protein and disease risk. We investigated the frequency of function-associated IL18 gene haplotypes in an extensive sample (n=2357) of African populations from across the continent. A previously identified five tagging SNP (single-nucleotide polymorphism) haplotype (here designated hGTATA), known to be associated with lower levels of IL-18, was observed at a frequency of 27% in a British population of recent European ancestry, but was found at low frequency (African populations. Potentially protective variants may, as a consequence, be found at low frequency in African individuals and may confer a difference in disease risk.

    It has been suggested that interleukin (IL)-18 plays a role in the development of inflammatory and fibrosing lung diseases. Associations of polymorphisms in the genes coding for IL-18 (108 /G-656T, C-607A, G-137C, T113G, C127T) and its receptor (IL8R1/C-69T) with coal workers' pneumoconiosis (CWP) were studied in 200 miners who were examined in 1990, 1994 and 1999. Coal-dust exposure was assessed according to job history and ambient measures. The main health outcome was lung computed tomography (CT) score in 1990. Internal coherence was assessed by studying CT score in 1994, 4-yr change in CT score and CWP incidence and prevalence. CT score in 1990 was a good predictor of radiographic grade in 1999 and, therefore, an appropriate subclinical quantitative trait. The IL18 -137C allele was associated with lower CT score in 1990 and 1994 (11.24 versus 1.69 and 1.57 versus 2.46, respectively), slower progression of CT score between 1990 and 1994 and lower pneumoconiosis prevalence in 1999 relative to the G allele (0.33 versus 0.77 and 8.2 versus 19.6%, respectively). Smoking- or dust-adjustment, and stratification on IL18R1 genotype and adjustment for haplotype effects did not change the conclusions. In conclusion, the results of the present study suggest a role for IL18 in reducing the development of this fibrosing lung disease.

    The multifunctional cytokine interleukin-18 (IL-18) is an important mediator in intestinal inflammatory processes. The aim of this study was to evaluate the constitutive expression of IL-18 and its receptors (IL-18Ralpha and IL-18Rbeta) in intestinal epithelial cells (IEC) stimulated by tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma). In addition, cellular proliferation and evaluation of brush border enzymes as differentiation markers were studied. Nontransformed rat intestinal epithelial IEC-6 cells were grown on an extracellular matrix (ECM) in medium with or without TNF-alpha, IFN-gamma, or a combination of both. Gene expression of IL-18, its receptors and apoptotic markers was evaluated using real-time PCR. Expression of IL-18Ralpha protein was demonstrated by flow cytometry and Western blot. Enzymatic activities of brush border enzymes and caspase-1 were determined. The constitutive expression of IL-18, IL-18Ralpha and IL-18Rbeta mRNAs and proteins were detected in IEC-6 cells. The biologically active form of IL-18 was released in response to TNF-alpha and IFN-gamma treatment. Exogenous IL-18 had no effect on cellular proliferation, brush border enzyme activities, and gene expression of apoptotic markers. However, the addition of IL-18 stimulated production and release of the chemokine IL-8. These data suggest that IEC-6 cells may be not only a source of IL-18 but also a target for its action.

    Chagas disease is a parasitic disorder caused by the infection with the flagellated protozoan Trypanosoma cruzi. According to the World Health Organization, more than six million people are currently infected in endemic regions. Genetic factors have been proposed to influence predisposition to infection and development of severe clinical phenotypes like chronic Chagas cardiomyopathy (CCC). Interleukin 18 (IL18) encodes a proinflammatory cytokine that has been proposed to be involved in controlling T. cruzi infection. In this study, we analyzed the possible role of six IL18 gene variants (rs5744258, rs360722, rs2043055, rs187238, rs1946518 and rs360719), which cover most of the variation within the locus, in the susceptibility to infection by T. cruzi and/or CCC. In total, 1,171 individuals from a Colombian region endemic for Chagas disease, classified as seronegative (n = 595), seropositive asymptomatic (n = 175) and CCC (n = 401), were genotyped using TaqMan probes. Significant associations with T. cruzi infection were observed when comparing seronegative and seropositive individuals for rs187238 (P = 2.18E-03, OR = 0.77), rs360719 (P = 1.49E-03, OR = 0.76), rs2043055 (P = 2.52E-03, OR = 1.29), and rs1946518 (P = 0.0162, OR = 1.22). However, dependence analyses suggested that the association was mainly driven by the polymorphism rs360719. This variant is located within the promoter region of the IL18 gene, and it has been described that it creates a binding site for the transcription factor OCT-1 affecting IL-18 expression levels. In addition, no evidence of association was observed between any of the analyzed IL18 gene polymorphisms and the development of CCC. In summary, our data suggest that genetic variation within the promoter region of IL18 is directly involved in the susceptibility to infection by T. cruzi, which provides novel insight into disease pathophysiology and adds new perspectives to achieve a more effective disease control.

    Objective: To determine serum interleukin-18 (IL-18) levels and their clinical significance in patients with prostate cancer. Methods: Peripheral blood samples were obtained from 38 nonmetastatic and 18 metastatic prostate cancer patients who underwent curative surgery and from 25 healthy volunteers. The serum IL-18 level was determined in each sample with the enzyme-linked immunosorbent assay. Results: The levels of serum IL-18 were increased significantly in prostate cancer patients compared with control subjects (P < 0.05). Serum IL-18 levels were significantly higher in the metastatic patients compared with the nonmetastatic patients (P < 0.01). Patients with bone metastasis had higher serum IL-18 levels compared with patients with liver and lung metastasis (P < 0.01). When the patients were subdivided into groups, it was found that the serum IL-18 levels in patients with T2, T3 and T4 stage were significantly higher than that of T1 stage patients (P < 0.01). Patients with IL-18 levels ≥ 316 pg/mL experienced a significantly lower survival rate compared with the patients who had IL-18levels < 316 pg/mL after undergoing surgery (P < 0.05). The serum IL-18 level was identified as an independent postoperative prognostic factor in multivariate survival analysis using a Cox proportional hazards model (hazard ratio, 4.21; P = 0.02).Conclusion: The serum IL-18 level may be a useful marker in monitoring prostate cancer patients. IL-18 activity in prostate cancer patients with bone metastasis may be more valuable in the follow-up.

    Interleukin 18 (IL18) stimulates interferon-γ production in Th1 cells which are prominent in the thyroid of Hashimoto thyroiditis (HT). We investigated the association between the IL18 gene and HT. There were 116 children with HT and 1272 controls. rs187238 and rs1946518 in the promoter region of the IL18 gene were genotyped. Differences in genotype, allele, carrier, and haplotype distributions between patients and controls were compared. A Pc value <0.05 was considered significant. The frequency of the C/G genotype of rs187238 was significantly higher in patients and conferred a risk of HT (OR, 1.96; 95% CI, 1.30-2.95; Pc, 0.0021). So did the frequencies of allele C (OR, 1.73; 95% CI, 1.22-2.44; Pc, 0.0035) and carrier C (OR, 1.96; 95% CI, 1.31-2.92; Pc, 0.0017), however the frequency of the G/G genotype was significantly lower in patients than in controls (OR, 0.51; 95% CI, 0.34-0.76; Pc, 0.0034). There was no association between HT and rs1946518. The CT haplotype was significantly more frequent in patients than in controls and conferred a risk of HT (OR, 1.76; 95% CI, 1.24-2.49; Pc, 0.0049). We concluded that the IL18 gene was associated with HT in children. The rs187238C allele and CT haplotype conferred a risk of HT.

    The giant panda (Ailuropoda melanoleuca) is an endangered species. Interleukin-18 (IL-18) plays an important role in the innate and adaptive immune responses by inducing IFN-γ. IL-18 has been implicated in the pathogenesis of various diseases. IL-18 binding protein (IL-18BP) is an intrinsic inhibitor of IL-18 that possesses higher affinity to IL-18. In this study, we cloned and characterized IL-18BP in giant panda (AmIL-18BP) from the spleen. The amino acid sequence of giant panda IL-18BP ORF shared about 65% identities with other species. To evaluate the effects of AmIL-18BP on the immune responses, we expressed the recombinant AmIL-18BP in Escherichia coli BL21 (DE3).The fusing protein PET-AmIL-18BP was purified by nickel affinity column chromatography. The biological function of purified PET-AmIL-18BP was determined on mice splenocyte by qRT-PCR. The results showed that AmIL-18BP was functional and could significantly reduce IFN-γ production in murine splenocytes. These results will facilitate the study of protecting giant panda on etiology and immunology.

    Full Text Available In this study, we first measured some cytokine concentrations in the serum of patients treated with Juzentaihoto (JTT. Of the cytokines measured interleukin (IL -18 was the most prominently up-regulated cytokine in the serum of patients under long term JTT administration. We next evaluated the effects of JTT in mice, focusing especially on natural killer T (NKT cell induction. Mice fed JTT were compared to control group ones. After sacrifice, the liver was fixed, embedded and stained. Transmission electron microscope (TEM observations were performed. Although the mice receiving the herbal medicine had same appearance, their livers were infiltrated with massive mononuclear cells, some of which were aggregated to form clusters. Immunohistochemical staining revealed that there was abundant cytokine expression of IL-12 and IL-18 in the liver of JTT treated mice. To clarify what the key molecules that induce immunological restoration with JTT might be, we next examined in vitro lymphocyte cultures. Mononuclear cells isolated and prepared from healthy volunteers were cultured with and without JTT. Within 24 hours, JTT induced the IL-12 and IL-18 production and later (72 hours induction of interferon (IFN-gamma. Oral administration of JTT may induce the expression of IL-12 in the early stage, and IL-18 in the chronic stage, followed by NKT induction. Their activation, following immunological restoration could contribute to anti-tumor effects.

    IL-18 and IL-18 binding protein (IL-18BP) are two newly described opponents in the cytokine network. Local concentrations of these two players may determine biological functions of IL-18 in the context of inflammation, infection, and cancer. As IL-18 appears to be involved in the pathogenesis of Crohn's disease and may modulate tumor growth, we investigated the IL-18/IL-18BPa system in the human colon carcinoma/epithelial cell line DLD-1. In this study, we report that IFN-gamma induces expression and release of IL-18BPa from DLD-1 cells. mRNA induction and secretion of IL-18BPa immunoreactivity were associated with an activity that significantly impaired release of IFN-gamma by IL-12/IL-18-stimulated PBMC. Inducibility of IL-18BPa by IFN-gamma was also observed in LoVo, Caco-2, and HCT116 human colon carcinoma cell lines and in the human keratinocyte cell line HaCaT. Induction of IL-18BPa in colon carcinoma/epithelial cell lines was suppressed by coincubation with sodium butyrate. IFN-gamma-mediated IL-18BPa and its suppression by sodium butyrate were confirmed in organ cultures of intestinal colonic biopsy specimens. In contrast, sodium butyrate did not modulate expression of IL-18. The present data suggest that IFN-gamma may limit biological functions of IL-18 at sites of colonic immune activation by inducing IL-18BPa production. Down-regulation of IL-18BPa by sodium butyrate suggests that reinforcement of local IL-18 activity may contribute to actions of this short-chain fatty acid in the colonic microenvironment.

    To investigate the role of IL-18 andIL-18 binding protein (IL-18BP) in the pathogenesis of psoriasis, PT-PCR was used to semi-quantitatively analyze the mRNA expression of IL-18, AcPL (accessory protein-like) and IL-18BP in 12 psoriatic lesions and in 6 normal skin tissues. The results showed that IL-18 and AcPL mRNA were present in all specimens from 6 normal skin and 12 pieces of psoriatic skin, and IL-18 and AcPL showed relatively stronger intensity in the psoriatic skin compared with those seen in normal skin (P<0. 01). Amplified bands indicating the expression of IL18BP mRNA were weakly positive in all samples of normal skin. In contrast, the PCR products for IL-18BP were distinctly visible in all specimens of psoriatic lesions (P< 0. 01). These findings demonstrate that IL-18 is constitutively synthesized by human keratinocytes and involved in the development of the Th1 response in psoriatic lesions, and its bioactivity appears to be closely regulated by cutaneous inflammation.

    Full Text Available Abstract Background Interleukin-18 is a pro-inflammatory cytokine suspected to be associated with atherosclerosis and its complications. We had previously shown that one single nucleotide polymorphism (SNP of the IL18 gene was associated with cardiovascular disease (CVD through an interaction with smoking. As a further step for elucidating the contribution of the IL-18 pathway to the etiology of CVD, we here investigated the association between the genetic variability of two IL-18 receptor genes, IL18R1 and IL18RAP, with the risk of developing CVD. Methods Eleven tagging SNPs, 5 in IL18R1 and 6 in IL18RAP, characterizing the haplotypic variability of the corresponding genes; were genotyped in 5 European prospective CVD cohorts including 1416 cases and 1772 non-cases, as part of the MORGAM project. Both single-locus and haplotypes analyses were carried out to investigate the association of these SNPs with CVD. Results We did not find any significant differences in allele, genotype and haplotype frequencies between cases and non-cases for either of the two genes. Moreover, the search for interactions between SNPs located in different genes, including 5 IL18 SNPs previously studied in the MORGAM project, and between SNPs and environmental factors remained unfruitful. Conclusion Our analysis suggests that the variability of IL18R1 and IL18RAP genes are unlikely to contribute to modulate the risk of CVD.

    IL-18 is a pro-inflammatory cytokine belonging to the IL-1 family and is produced in the body from macrophages, epithelial and dendritic cells, keratinocytes, adrenal cortex etc. The cytokine is produced as an inactive precursor that is cleaved inside cells into its mature form by activated caspase 1, which exists as an inactive precursor in human cells and requires assembly of an inflammasomes for its activation. We show here for the first time that human platelets contain transcripts for the IL-18 gene. They synthesize the cytokine de novo, process and release it upon activation. The activation also results in the assembly of an inflammasome and activation of caspase-1. Platelets also contain the IL-18 antagonist, the IL-18-Binding Protein (IL-18BP); however, it is not synthesized in them de novo, is present in pre-made form and is released irrespective of platelet activation. IL-18 and IL-18BP co-localize to α granules inside platelets and are secreted out with different kinetics. Platelet activation contributes to plasma concentrations in healthy individuals, as their plasma samples contain abundant IL-18, while their platelet-poor plasma samples contain very little amounts of the cytokine. The plasma and PPP samples from these donors, however, contain comparable amounts of IL-18BP. Unlike healthy individuals, the platelet-poor plasma from HIV-infected individuals contains significant amounts of IL-18. Our findings have important implications for viral infections and other human diseases that are accompanied by platelet activation.

    Currently, the low efficacy of antinociceptive drugs for the treatment of neuropathic pain is a major therapeutic problem. Here, we show the potential role of interleukin (IL)-18 signaling in this phenomenon. IL-18 is an important molecule that performs various crucial functions, including the alteration of nociceptive transmission in response to neuropathic pain. We have studied the changes in the mRNA and protein levels (qRT-PCR and Western blot analysis, respectively) of IL-18, IL-18-binding protein (IL-18BP) and the IL-18 receptor (IL-18R) over time in rats following chronic constriction injury (CCI) of the sciatic nerve. Our study demonstrated that the spinal levels of IL-18BP were slightly downregulated at days 7 and 14 in the rats subjected to CCI. In contrast, the IL-18 and IL-18R mRNA expression and protein levels were elevated in the ipsilateral spinal cord on days 2, 7 and 14. Moreover, in rats exposed to a single intrathecal administration of IL-18BP (50 and 100 ng) 7 or 14 days following CCI, symptoms of neuropathic pain were attenuated, and the analgesia pursuant to morphine and buprenorphine (0.5 and 2.5 μg) was enhanced. In summary, the restoration of the analgesic activity of morphine and buprenorphine via the blockade of IL-18 signaling suggests that increased IL-18 pathway may account for the decreased analgesic efficacy of opioids for neuropathic pain.

    Full Text Available IL-18 has proinflammatory effects and participates in both innate and adaptive cellular and humoral immunity. A number of SNPs that influence IL-18 production are found in the gene promoter region. We investigated the association of SNPs in the IL-18 promoter at −607 and −137 with the level of IL-18 protein production by PBMC from healthy donors from Southwestern Siberia. The genetic distribution of these SNPs in the promoter site was established by PCR. IL-18 protein production was determined by ELISA. Our results showed that PBMC from donors carrying allele 137C have lower levels of both spontaneous and LPS-stimulated IL-18 production. In contrast, PBMC from donors carrying allele 607A showed significant increases in spontaneous and stimulated IL-18 production compared to wild type. Our study suggests that the SNPs −607 and −137 in the promoter region of the IL-18 gene influence the level of IL-18 protein production by PBMC from healthy donors in Southwestern Siberia.

    Interleukin-18 (IL-18) was discovered as an interferon-γ-inducing factor and has been regarded as a proinflammatory cytokine. However, IL-18 is ubiquitously expressed both in immune/inflammatory cells and in nonimmune cells, and its biological roles have not been sufficiently elucidated. Here, we demonstrate that IL-18-deficient [IL-18 knockout (KO)] mice have heart abnormalities that may be related to impaired autophagy. In endurance running tests, IL-18KO mice ran significantly shorter distances compared with wild-type (WT) mice. Echocardiographs indicated disability in the systolic and diastolic functions of the IL-18KO mouse heart. Immunostaining of connexin 43 showed heterogeneous localization of gap junctions in the lateral membranes of the IL-18KO cardiac myocytes. Western blotting analysis revealed decreased phosphorylated connexin 43 in the IL-18KO heart. Electron microscopy revealed unusual localization of intercalated disks, swollen or damaged mitochondria, and broad, indistinct Z-lines in the IL-18KO heart. In accordance with the morphological observation, mitochondrial respiratory function, including that of complexes I and IV, was impaired, and production of reactive oxygen species was augmented in IL-18KO hearts. Notably, levels of LC3-II were markedly lower in the IL-18KO hearts than in WT hearts. In the culture of cardiac myocytes of IL-18KO neonates, exogenous IL-18 upregulated LC3-II and increased the number of intact mitochondria with high mitochondrial membrane potential. These results indicated that IL-18 has roles apart from those as a proinflammatory cytokine in cardiac myocytes and suggested that IL-18 contributes to the homeostatic maintenance of mitochondrial function and gap-junction turnover in cardiac myocytes, possibly by upregulating autophagy.

    To study the treatment of experimental metastatic lung carcinoma by intratracheal injection of IL-18 gene recombinant adenovirus. Methods: (1)The mouse IL-18 mRNA was detected by RT-PCR, and the concentration of IL-18 and associated cytokines in lung lavages and blood were determined by ELISA at different time points after intratracheal injection of IL-18 recombinant adenovirus. (2)The lung metastasis nodes, mouse survival periods and survival rates were evaluated. NK activity and CTL activity were determined by 51Cr 4 h release method. Results: (1)IL-18 mRNA was detectable in lung tissue 6 h after intratracheal use of IL-18 recombinant adenovirus, and the concentration of IL-18 in lung lavage was higher than that in pelipheral blood. Neither IL-18 mRNA nor IL-18 was detectable in control group. (2) Intratracheal use of IL-18 recombinant adenovirus resulted in increased CTL and NK activity, longer survival time and higher survival rates compared with the control group, showing significant therapeutic effect on experimental lung metastasis. Conclusion: Intratracheal use of adenovirus vector containing IL-18 gene has therapeutic effect on the lung metastasis, denoting that gene therapy of lung diseases could be applied through airway directly with recombinant adenovirus.

    Our previous studies showed that the down-modulation of IL-18-induced immune response caused by oncoproteins E6 and E7 as one of the mechanisms underlying immune escape in HPV-induced cervical cancer cells. E42 residue of IL-18 also appears to be critical in the activity of IL-18. Single point mutation E42 in IL-18 show promise in the study of IL-18 binding motifs for HPV oncoproteins. We attempted to ascertain whether site-specific IL-18 mutant E42A would modulate the inhibitory effects of IL-18-induced immune responses via the HPV 16 E6 and E7 oncoproteins. Compared to wild type IL-18, E42A-induced IFN-gamma production was not inhibited by HPV 16 E6 and E7. In vitro and in vivo binding assays have also revealed that E6 and E7 do not result in the inhibition of the binding of E42A to its IL-18 receptor alpha chain. There were no effects on the E42A-induced phosphorylations of p38 and JNK observed in the presence of E6 or E7. The degradation of IkappaB by E42A was not affected by E6 or E7 in NK0 cells. Moreover, E42A-induced NF-kappaB activation was also not inhibited by these oncoproteins. These results suggest that E42A is a stronger activator than wild type IL-18, and is not susceptible to inhibition by the HPV oncoproteins E6 and E7. Thus, it is suggested that E42A could be used in immunotherapy for patients with cervical cancer.

  20. IL-27 Regulates IL-18 binding protein in skin resident cells.

    Directory of Open Access Journals (Sweden)

    Miriam Wittmann

    Full Text Available IL-18 is an important mediator involved in chronic inflammatory conditions such as cutaneous lupus erythematosus, psoriasis and chronic eczema. An imbalance between IL-18 and its endogenous antagonist IL-18 binding protein (BP may account for increased IL-18 activity. IL-27 is a cytokine with dual function displaying pro- and anti-inflammatory properties. Here we provide evidence for a yet not described anti-inflammatory mode of action on skin resident cells. Human keratinocytes and surprisingly also fibroblasts (which do not produce any IL-18 show a robust, dose-dependent and highly inducible mRNA expression and secretion of IL-18BP upon IL-27 stimulation. Other IL-12 family members failed to induce IL-18BP. The production of IL-18BP peaked between 48-72 h after stimulation and was sustained for up to 96 h. Investigation of the signalling pathway showed that IL-27 activates STAT1 in human keratinocytes and that a proximal GAS site at the IL-18BP promoter is of importance for the functional activity of IL-27. The data are in support of a significant anti-inflammatory effect of IL-27 on skin resident cells. An important novel property of IL-27 in skin pathobiology may be to counter-regulate IL-18 activities by acting on keratinocytes and importantly also on dermal fibroblasts.

    Full Text Available The role of IL-18 in the pathogenesis of systemic lupus erythematosus is still not definitively solved. In this study, we generated MRLlpr mice, which develop a disease resembling systemic lupus erythematosus, genetically devoid of IL-18 expression. These mice in comparison to IL-18-competent MRLlpr mice show reduced signs of renal pathogenesis, while other parameters such as mean survival time, lymphadenopathy, constitutive interferon-γ production, and frequency of CD3+B220+ abnormal T cells were without differences. We conclude that in the systemic lupus erythematosus syndrom IL-18 is involved specifically in the renal pathogenesis.

    Full Text Available Predominantly antibody deficiencies are a category of primary immunodeficiency diseases, whichconsist of several rare disorders such as common variable immunodeficiency (CVID and X-linked agammaglobulinemia (XLA. We evaluated the effects of CVID and XLA patients’ sera as a source of microenviromental factors on maturation and function of monocyte-derived DCs.Blood was collected from 10 CVID and 5 XLA patients before immunoglobulin replacementtherapy and also from 8 healthy volunteers in order to obtain necessary sera for this study. Monocyte derived DCs were generated from blood cells obtained from healthy volunteers in the presence of GM-CSF, IL-4 and 10% serum concentrations from cases and controls. Immature DCs were incubated with monocyte conditioned medium (MCM and TNF-α in order to generate mature DCs. Interleukin 18 (IL-18 production by CD40L-activated mature DCs was measured after 24 hours of culture in vitro.IL-18 production by DCs generated in the presence of CVID and XLA patients’ sera were6.75±2.59 and 7.08±1.75 ng/ml, respectively, which were significantly higher than normal serumconditioned DCs (3.55±0.68 ng/ml.These results suggest that the sera of patients with predominantly antibody deficiencies maycontain soluble factor(s that can induce a significant increase in IL-18 production by DCs.

  5. IL-18 inhibits growth of murine orthotopic prostate carcinomas via both adaptive and innate immune mechanisms.

    Directory of Open Access Journals (Sweden)

    Brian Wan-Chi Tse

    Full Text Available Interleukin(IL-18 is a pleiotrophic cytokine with functions in immune modulation, angiogenesis and bone metabolism. In this study, the potential of IL-18 as an immunotherapy for prostate cancer (PCa was examined using the murine model of prostate carcinoma, RM1 and a bone metastatic variant RM1(BM/B4H7-luc. RM1 and RM1(BM/B4H7-luc cells were stably transfected to express bioactive IL-18. These cells were implanted into syngeneic immunocompetent mice, with or without an IL-18-neutralising antibody (αIL-18, SK113AE4. IL-18 significantly inhibited the growth of both subcutaneous and orthotopic RM1 tumors and the IL-18 neutralizing antibody abrogated the tumor growth-inhibition. In vivo neutralization of interferon-gamma (IFN-γ completely eliminated the anti-tumor effects of IL-18 confirming an essential role of IFN-γ as a down-stream mediator of the anti-tumor activity of IL-18. Tumors from mice in which IL-18 and/or IFN-γ was neutralized contained significantly fewer CD4(+ and CD8(+ T cells than those with functional IL-18. The essential role of adaptive immunity was demonstrated as tumors grew more rapidly in RAG1(-/- mice or in mice depleted of CD4(+ and/or CD8(+ cells than in normal mice. The tumors in RAG1(-/- mice were also significantly smaller when IL-18 was present, indicating that innate immune mechanisms are involved. IL-18 also induced an increase in tumor infiltration of macrophages and neutrophils but not NK cells. In other experiments, direct injection of recombinant IL-18 into established tumors also inhibited tumor growth, which was associated with an increase in intratumoral macrophages, but not T cells. These results suggest that local IL-18 in the tumor environment can significantly potentiate anti-tumor immunity in the prostate and clearly demonstrate that this effect is mediated by innate and adaptive immune mechanisms.

    Full Text Available OBJECTIVE: Interleukin (IL-18 has been associated with severity of atherosclerosis and discussed to predict cardiovascular (CV events. We have previously shown that the IL-18+183 G-allele significantly reduces IL-18 levels. This study was aimed to investigate the prognostic significance of the IL-18+183 A/G polymorphism (rs5744292, single and in coexistence with the matrix metalloproteinase (MMP-9 -1562 C/T (rs3918242 polymorphism, in patients with stable coronary artery disease (CAD. Serum levels of IL-18, MMP-9 and tissue inhibitor of matrix metalloproteinase (TIMP-1 were additionally assessed. METHODS: 1001 patients with angiographically verified CAD were genotyped and the biomarkers were measured accordingly. After two years follow-up, 10.6% experienced new clinical events; acute myocardial infarction (AMI, stroke, unstable angina pectoris and death. RESULTS: The IL-18+183 G-allele associated with 35% risk reduction in composite endpoints after adjusting for potential covariates (p = 0.044. The IL-18+183 AA/MMP-9 -1562 CT/TT combined genotypes associated with a significant increase in risk of composite endpoints (OR = 1.87; 95% CI = 1.13-3.11, p = 0.015, adjusted. Patients with clinical events presented with significantly higher IL-18 levels as compared to patients without (p = 0.011, adjusted. The upper tertile of IL-18 levels associated with an increase in risk of AMI as compared to lower tertiles (OR = 2.36; 95% CI = 1.20-4.64, p = 0.013, adjusted. CONCLUSION: The IL-18+183 A/G polymorphism, single and in combination with MMP-9 genotypes, may influence the risk of clinical events in stable CAD patients.

    Autophagy is an important component of the immune response. However, the functions of autophagy in human diseases are much less understood. We studied biological consequences of autophagy deficiency in mice lacking the essential autophagy gene Atg7 or Atg5 in myeloid cells. Surprisingly, these mice presented with spontaneous sterile lung inflammation, characterized by marked recruitment of inflammatory cells, submucosal thickening, goblet cell metaplasia, and increased collagen content. Lung inflammation was associated with increase in several proinflammatory cytokines in the bronchoalveolar lavage and in serum. This inflammation was largely driven by IL-18 as a result of constitutive inflammasome activation. Following i.p. LPS injection, autophagy-deficient mice had higher levels of proinflammatory cytokines in lungs and in serum, as well as increased mortality, than control mice. Intranasal bleomycin challenge exacerbated lung inflammation in autophagy-deficient mice and produced more severe fibrotic changes than in control mice. These results uncover a new and important role for autophagy as negative regulator of lung inflammation.

    Full Text Available Aims. The influence of interleukin-10 (IL-10 and interleukin-18 (IL-18 polymorphisms on tacrolimus pharmacokinetics had been described in liver and kidney transplantation. The expression of cytokines varied in different kinds of transplantation. The influence of IL-10 and IL-18 genetic polymorphisms on the pharmacokinetic parameters of tacrolimus remains unclear in lung transplantation. Methods. 51 lung transplant patients at Shanghai Pulmonary Hospital were included. IL-18 polymorphisms (rs5744247 and rs1946518, IL-10 polymorphisms (rs1800896, rs1800872, and rs3021097, and CYP3A5 rs776746 were genotyped. Dose-adjusted trough blood concentrations (C/D ratio, mg/kg body weight in lung transplant patients during the first 4 postoperative weeks were calculated. Results. IL-18 rs5744247 allele C and rs1946518 allele A were associated with fast tacrolimus metabolism. Combined analysis showed that the numbers of low IL-18 mRNA expression alleles had positive correlation with tacrolimus C/D ratios in lung transplant recipients. The influence of IL-18 polymorphisms on tacrolimus C/D ratios was observed in CYP3A5 expresser recipients, but not in CYP3A5 nonexpresser recipients. No clinical significance of tacrolimus C/D ratios difference of IL-10 polymorphisms was found in our data. Conclusions. IL-18 polymorphisms may influence tacrolimus elimination in lung transplantation patients.

    Whilst BCG inhibits allergic airway responses in murine models, IL-18 has adversary effects depending on its environment. We therefore constructed a BCG strain producing murine IL-18 (BCG-IL-18) and evaluated its efficiency to prevent an asthma-like reaction in mice. BALB/cByJ mice were sensitized (day (D) 1 and D10) by intraperitoneal injection of ovalbumin (OVA)-alum and primary (D20–22) and secondary (D62, 63) challenged with OVA aerosols. BCG or BCG-IL-18 were intraperitonealy administered 1 hour before each immunization (D1 and D10). BCG-IL-18 and BCG were shown to similarly inhibit the development of AHR, mucus production, eosinophil influx, and local Th2 cytokine production in BAL, both after the primary and secondary challenge. These data show that IL-18 did not increase allergic airway responses in the context of the mycobacterial infection, and suggest that BCG-IL-18 and BCG are able to prevent the development of local Th2 responses and therefore inhibit allergen-induced airway responses even after restimulation.

    Full Text Available Background/Aims: To investigate the role of angiopoietin-2 (Ang-2 and IL-18 in the pathogenesis of diabetic nephropathy (DN and the molecular mechanisms through which alprostadil protects renal function. Methods: DN was induced by streptozotocin and intraperitoneal injection of alprostadil was given to diabetic mice. After 2, 4 and 8 weeks of alprostadil treatment, the mRNA and protein expression of kidney Ang-2 and IL-18 were detected by reverse transcription PCR, Western blot and immunohistochemistry analyses. Mouse glomerular endothelial cells (GEnCs were cultured in high glucose and treated with alprostadil. After transfection with an Ang-2-pcDNA and Ang-2-siRNA, both Ang-2 and IL-18 expression were measured by Western blot analyses. Results: Alprostadil treatment caused a significant decrease in the renal damage parameters. Both Ang-2 and IL-18 were significantly increased in DN mice and in GEnCs cultured in high glucose; however, their expression was greatly reduced by alprostadil treatment. Ang-2 could also increase IL-18 expression in cultured endothelial cells under high glucose, and this response was partially blocked by Ang-2 siRNA. Conclusions: Ang-2 and IL-18 may be associated with the development and progression of DN in mice. Alprostadil treatment can protect renal function by reducing proteinuria. These effects are mediated, at least in part, through down-regulation of Ang-2 and IL-18 expression.

    Full Text Available Background/aims: The pathogenesis of intrahepatic cholestasis of pregnancy (ICP is poorly understood. Objective: This study aimed to explore the possible effect of HDAC3 (histone deacetylase on cytokines IL-18, IL-12 and TNF-α in ICP. Methods: Serum levels of cytokines IL-18, IL-12 and TNF-α, bile acids and hepatic function parameters were measured. The expression of HDAC3 in the placenta was determined by immunohistochemistry (IHC, western blotting and RT-PCR. Results: IL-18, IL-12 and TNF-α serum levels were significantly higher in the severe ICP group than in the mild ICP group and the control group, and the difference between the mild ICP group and control group was not significant. HDAC3 protein expression was identified in the nucleus of the placental trophoblast by IHC. HDAC3 mRNA and protein expression were significantly lower in the ICP groups (mild ICP and severe ICP groups than in the control groups, and no significant difference was found between the mild ICP and severe ICP groups. Conclusions: The low expression of HDAC3 and overexpession of inflammatory cytokines (IL-18, IL-12 and TNF-α in ICP may be involved in liver cell apoptosis. We suspect that HDAC3 may play an important role in the pathophysiology of ICP.

    Objective To investigate the levels of IL-18 in the bone marrow of both normal subjects a nd patients with hematological diseases and to determine the possible significan ce of IL-18 in pathogenesis of some hematological malignancies. Methods The IL-18 mRNA levels in the bone marrow of 140 patients with hematological dis eases and 15 normal donors were determined by the semi-quantitative reverse tra nscriptase polymerase chain reaction (RT-PCR). Immunohistochemical method was used to detect IL-18 protein in 12 patients with acute myeloid leukemia (AML). The possible regulation of IL-18 for proliferation of some leukemia cells was investigated using antisense techniques.Results IL-18 mRNA levels were obviously higher in the patients with leukemia or other malignant hematological diseases (OMHD) than in normal donors. However, no sign ificant difference was found in the level of transcription between patients with iron deficiency anemia (IDA) and normal controls. Immunohistochemical method c onfirmed the presence of IL-18 protein in 10 out of 12 AML cases with positive transcription. By 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium b romide (MTT) assay, IL-18 antisense oligodeoxynucleotides (ASON) clearly inhibi ted the growth of J6-1 and HL-60 cells (42% and 12% inhibited, respectively) i n a dose-dependant manner.Conclusions IL-18 was detected at elevated levels in the bone marrow of patients with some hematological malignancies, and might be involved in the proliferation of certai n leukemic cells in vivo through an autocrine mechanism.

    Dysregulation of airway inflammation contributes to lung disease in cystic fibrosis (CF). Inflammation is mediated by inflammatory cytokines, including IL-8, which illustrates an increase in biological half-life and proinflammatory activity when bound to glycosaminoglycans (GAGs). The aim of this project was to compare IL-8 and IL-18 for their relative stability, activity, and interaction with GAGs, including chondroitin sulfate, hyaluronic acid, and heparan sulfate, present in high quantities in the lungs of patients with CF. Bronchoalveolar lavage fluid was collected from patients with CF (n = 28), non-CF controls (n = 14), and patients with chronic obstructive pulmonary disease (n = 12). Increased levels of IL-8 and reduced concentrations of IL-18 were detected in bronchial samples obtained from CF individuals. The low level of IL-18 was not a defect in IL-18 production, as the pro- and mature forms of the molecule were expressed and produced by CF epithelial cells and monocytes. There was, however, a marked competition between IL-8 and IL-18 for binding to GAGs. A pronounced loss of IL-18 binding capacity occurred in the presence of IL-8, which displaced IL-18 from these anionic-matrices, rendering the cytokine susceptible to proteolytic degradation by neutrophil elastase. As a biological consequence of IL-18 degradation, reduced levels of IL-2 were secreted by Jurkat T lymphocytes. In conclusion, a novel mechanism has been identified highlighting the potential of IL-8 to determine the fate of other inflammatory molecules, such as IL-18, within the inflammatory milieu of the CF lung.

  17. IL-18 induces airway hyperresponsiveness and pulmonary inflammation via CD4+ T cell and IL-13.

    Full Text Available IL-18 plays a key role in the pathogenesis of pulmonary inflammatory diseases including pulmonary infection, pulmonary fibrosis, lung injury and chronic obstructive pulmonary disease (COPD. However, it is unknown whether IL-18 plays any role in the pathogenesis of asthma. We hypothesized that overexpression of mature IL-18 protein in the lungs may exacerbate disease activities of asthma. We established lung-specific IL-18 transgenic mice on a Balb/c genetic background. Female mice sensitized- and challenged- with antigen (ovalbumin were used as a mouse asthma model. Pulmonary inflammation and emphysema were not observed in the lungs of naïve transgenic mice. However, airway hyperresponsiveness and airway inflammatory cells accompanied with CD4(+ T cells, CD8(+ T cells, eosinophils, neutrophils, and macrophages were significantly increased in ovalbumin-sensitized and challenged transgenic mice, as compared to wild type Balb/c mice. We also demonstrate that IL-18 induces IFN-γ, IL-13, and eotaxin in the lungs of ovalbumin-sensitized and challenged transgenic mice along with an increase in IL-13 producing CD4(+ T cells. Treatment with anti-CD4 monoclonal antibody or deletion of the IL-13 gene improves ovalbumin-induced airway hyperresponsiveness and reduces airway inflammatory cells in transgenic mice. Overexpressing the IL-18 protein in the lungs induces type 1 and type 2 cytokines and airway inflammation, and results in increasing airway hyperresponsiveness via CD4(+ T cells and IL-13 in asthma.

    The inflammation induced by obesogenic diets is associated with deposition of fat in the liver. On the other hand, anti-inflammatory and immunosuppressive therapies may impact in body fat storage and in liver lipid dynamics. It is important to study specific inflammatory mediators in this context, since their role on hepatic damage is not fully clarified. This study aimed to evaluate the role of interleukin (IL)-18 and tumor necrosis factor (TNF) receptor in liver dysfunction induced by diet. Male C57BL/6 wild-type (WT), IL-18, and TNF receptor 1 knockout mice (IL-18(-/-) and TNFR1(-/-)) were divided according to the experimental diets: chow diet or a high-refined carbohydrate-containing diet. Alanine aminotransferase was quantified by colorimetric analysis. Total fat content in the liver was determined by Folch methods. Levels of TNF, IL-6, IL-4, and IL-13 in liver samples were measured by ELISA assay. IL-18 and TNFR knockout mice fed with chow diet showed higher liver triglycerides deposition than WT mice fed with the same diet (WT: 131.9 ± 24.5; IL-18(-/-): 239.4 ± 38.12*; TNF(-/-): 179.6 ± 50.45*; *P liver histopathological score and lower levels of TNF, IL-6, IL-4, and IL-13 in the liver. Interestingly, treatment with a high-carbohydrate diet did not exacerbate liver damage in IL-18(-/-) and TNFR1(-/-) mice. Our data suggest that IL-18 and TNF may be involved on hepatic homeostasis mainly in a context of a healthy diet.

Results The levels of IL-5,IL-15 and IL-18 were greatly increased in all patient groups than the control group (P<0.01). The levels of IL-5 ,IL-15 and IL-18 were greatly increased in AR and BA group than the group of BA and the group of AR.The level of IL-5 in the group of AR was higher than that in the group of BA.(P=0.003). The level of IL-18 in the group of BA was higher than that in the group of AR( P=0.001 ). Conclusions IL-5 ,IL-15 and IL-18play a prominent role in the pathogenesis of AR and BA. Inflammations in the group of AR accompanying BA group are much higher. there is difference in inflammations between BA and AR.

  20. An IFN-gamma-IL-18 signaling loop accelerates memory CD8+ T cell proliferation.

    Directory of Open Access Journals (Sweden)

    Yoshiko Iwai

    Full Text Available Rapid proliferation is one of the important features of memory CD8(+ T cells, ensuring rapid clearance of reinfection. Although several cytokines such as IL-15 and IL-7 regulate relatively slow homeostatic proliferation of memory T cells during the maintenance phase, it is unknown how memory T cells can proliferate more quickly than naïve T cells upon antigen stimulation. To examine antigen-specific CD8(+ T cell proliferation in recall responses in vivo, we targeted a model antigen, ovalbumin(OVA, to DEC-205(+ dendritic cells (DCs with a CD40 maturation stimulus. This led to the induction of functional memory CD8(+ T cells, which showed rapid proliferation and multiple cytokine production (IFN-gamma, IL-2, TNF-alpha during the secondary challenge to DC-targeted antigen. Upon antigen-presentation, IL-18, an IFN-gamma-inducing factor, accumulated at the DC:T cell synapse. Surprisingly, IFN-gamma receptors were required to augment IL-18 production from DCs. Mice genetically deficient for IL-18 or IFN-gamma-receptor 1 also showed delayed expansion of memory CD8(+ T cells in vivo. These results indicate that a positive regulatory loop involving IFN-gamma and IL-18 signaling contributes to the accelerated memory CD8(+ T cell proliferation during a recall response to antigen presented by DCs.

    2011-01-01

    Full Text Available The inflammasome is an important innate immune pathway that regulates at least two host responses protective against infections: (1 secretion of the proinflammatory cytokines IL-1β and IL-18 and (2 induction of pyroptosis, a form of cell death. Inflammasomes, of which different types have been identified, are multiprotein complexes containing pattern recognition receptors belonging to the Nod-like receptor family or the PYHIN family and the protease caspase-1. The molecular aspects involved in the activation of different inflammasomes by various pathogens are being rapidly elucidated, and their role during infections is being characterized. Production of IL-1β and IL-18 and induction of pyroptosis of the infected cell have been shown to be protective against many infectious agents. Here, we review the recent literature concerning inflammasome activation in the context of bacterial infections and identify important questions to be answered in the future.

    2016-05-01

    Diabetic vascular complication is a leading cause of diabetic nephropathy, a progressive increase in urinary albumin excretion coupled with elevated blood pressure leading to declined glomerular filtration and eventually end stage renal failure. There is growing evidence that activated inflammation is contributing factor to the pathogenesis of diabetic nephropathy. Meanwhile, IL-18, a member of the IL-1 family of inflammatory cytokines, is involved in the development and progression of diabetic nephropathy. However, the benefits derived from the current therapeutics for diabetic nephropathy strategies still provide imperfect protection against renal progression. This imperfection points to the need for newer therapeutic agents that have potential to affect primary mechanisms contributing to the pathogenesis of diabetic nephropathy. Therefore, the recognition of IL-18 as significant pathogenic mediators in diabetic nephropathy leaves open the possibility of new potential therapeutic targets.

    Tuberculosis remains an enormous global burden, despite wide vaccination coverage with the Bacillus Calmette-Guérin (BCG), the only vaccine available against this disease, indicating that BCG-driven immunity is insufficient to protect the human population against tuberculosis. In this study we constructed recombinant BCG producing human IL-18 (rBCGhIL-18) and investigated whether human IL-18 produced by rBCGhIL-18 modulates DC functions and enhances Th1 responses to mycobacterial antigens in humans. We found that the costimulatory CD86 and CD80 molecules were significantly upregulated on rBCGhIL-18-infected DCs, whereas the stimulation of DCs with nonrecombinant BCG was less effective. In contrast, both BCG strains decreased the DC-SIGN expression on human DCs. The rBCGhIL-18 increased IL-23, IL-10, and IP-10 production by DCs to a greater extent than nonrecombinant BCG. In a coculture system of CD4(+) T cells and loaded DCs, rBCGhIL-18 favoured strong IFN-γ but also IL-10 production by naive T cells but not by memory T cells. This was much less the case for nonrecombinant BCG. Thus the expression of IL-18 by recombinant BCG increases IL-23, IP-10, and IL-10 expression by human DCs and enhances their ability to induce IFN-γ and IL-10 expression by naive T cells, without affecting the maturation phenotype of the DCs.

    Objective: Interleukin-18(IL-18) is a cytokine with many functions. This study was to investigate the serum levels of IL-18 and their clinical significance in patients with colore3ctaql carcinomas. Methods: Peripheral blood samples were obtained from 106 patients with colorectal carcinoma and 60 volunteers. The serum IL-18 levels were determined in each sample with an enzyme-linked immunosorbent assay (ELISA). Results: In patients before 1997, the mean IL-18 level was 338.46 pg/ml; in patients after 1997, the mean IL-18 level was 328.85 pg/ml, there is no evidence of loss of IL-18 immunoreactivity after prolonged storage at -80℃. The mean serum IL-18 level in 106 patients with colorectal carcinoma was significantly higher compared with the 60 healthy volunteers (P0.05). The survival rate of patients with IL-18 levels ≥346 pg/ml (n=47 patients) was significantly worse compared with patients who had IL-18 levels <346 pg/ml(n=57 patients). The 5-year-survival rates were 5.3% and 18.6%, respectively. Multivariate analysis using a Cox proportional hazards model identified the serum IL-18 level as an independent prognostic factor for survival Conclusion: The serum IL-18 level has a significant correlation with survival curve. The serum IL-18 level may represent a significant postoperative prognostic determinant in patients with colorectal carcinoma.

    To analyze the antitumor potential and mechanism of action of simultaneous Newcastle disease virus (NDV) hemagglutinin-neuraminidase(HN) and human interleukin 18(hIL-18) gene transfer in C57BL/6 mice with H22 hepatoma,the mouse model with H22 hepatoma was established in C57BL/6 mice,and the antitumor effects of the combined application of NDV HN and hIL-18 were evaluated in vivo.The results show that the growth of established tumors in mice immunized with adenovirus(Ad)-HN in conjunction with Ad-hIL-18 was significantly inhibited compared with that in mice immunized with Ad-HN,Ad-hIL-18 alone,or the empty vector(Ad-mock).Furthermore,the immunization of mice with Ad-HN in conjunction with Ad-hlL-18 elicited strong natural killer activity and H22 tumor-specific cytotoxic T lymphocyte(CTL) responses in vivo.In addition,T cells from the lymph nodes of mice immunized with Ad-hIL-18 or Ad-HN+Ad-hIL-18 secreted high levels of the Th1 cytokine IL-2 and interferon-γ(IFN-y),indicating that the regression of tumor cells is related to a Th1-type dominant immune response.These results demonstrate that vaccination with NDV HN together with hIL-18 may be a novel and powerful strategy for cancer immunotherapy.

    2017-05-01

    Full Text Available In 2002, intracellular protein complexes known as the inflammasomes were discovered and were shown to have a crucial role in the sensing of intracellular pathogen- and danger-associated molecular patterns (PAMPs and DAMPs. Activation of the inflammasomes results in the processing and subsequent secretion of the pro-inflammatory cytokines IL-1β and IL-18. Several autoinflammatory disorders such as cryopyrin-associated periodic syndromes and Familial Mediterranean Fever have been associated with mutations of genes encoding inflammasome components. Moreover, the importance of IL-1 has been reported for an increasing number of autoinflammatory skin diseases including but not limited to deficiency of IL-1 receptor antagonist, mevalonate kinase deficiency and PAPA syndrome. Recent findings have revealed that excessive IL-1 release induced by harmful stimuli likely contributes to the pathogenesis of common dermatological diseases such as acne vulgaris or seborrheic dermatitis. A key pathogenic feature of these diseases is IL-1β-induced neutrophil recruitment to the skin. IL-1β blockade may therefore represent a promising therapeutic approach. Several case reports and clinical trials have demonstrated the efficacy of IL-1 inhibition in the treatment of these skin disorders. Next to the recombinant IL-1 receptor antagonist (IL-1Ra Anakinra and the soluble decoy Rilonacept, the anti-IL-1α monoclonal antibody MABp1 and anti-IL-1β Canakinumab but also Gevokizumab, LY2189102 and P2D7KK, offer valid alternatives to target IL-1. Although less thoroughly investigated, an involvement of IL-18 in the development of cutaneous inflammatory disorders is also suspected. The present review describes the role of IL-1 in diseases with skin involvement and gives an overview of the relevant studies discussing the therapeutic potential of modulating the secretion and activity of IL-1 and IL-18 in such diseases.

    In recent years, crosstalk between tumor microenvironment and cancer cells have received increasing attention. Accumulating research data suggests that leptin, a key adipokine secreted from adipocytes, plays important roles in breast cancer development. In our study, the effects of leptin on polarization of tumor-associated macrophages (TAMs) and promotion of the invasiveness of tumor cells were investigated. THP1 cells were used to differentiate M2 polarization macrophages. After stimulated by leptin, we established a co-culture system of tumor cells and macrophages to evaluate the function of leptin-induced macrophages in the migration and invasion of breast cancer cells. The gene and protein expressions were analyzed and the underlying mechanisms were evaluated. Moreover, pathological human specimens, and xenografts in nude mice, were detected to strengthen the in vitro results. Leptin elevated the expression of an array of cytokines in TAMs, IL-18 was the most increased, with an activation of the NF-κB/NF-κB1 signalling pathway. Additionally, after treated with leptin, TAMs significantly promoted the migration and invasion of breast cancer cells. However, these effects of leptin were abolished by the co-incubation of Bay11‑7082, a pharmacological NF-κB inhibitor. Leptin also directly stimulated IL-18 expression in breast cancer cells, which, differently, was via the PI3K/AKT-ATF-2 signaling pathway. In vivo studies showed that malignant breast carcinoma exhibited strong higher expression of Leptin, IL-8, and TAMs markers. Xenograft tumor-bearing mouse models showed that leptin significantly increased tumor volume, enhanced lung metastases, and increased expression of IL-8 and TAM markers, which were abolished by depletion of macrophages by clophosome-clodronate liposomes (CCL). Leptin could induce IL-18 expression both in TAMs and breast cancer cells. Leptin-induced IL-18 expression was regulated via NF-κB/NF-κB1 signaling in TAMs, while via PI3K

    Hexavalent chromium (CrVI) is a heavy metal widely used in more than 50 industries. Nephrotoxicity is a major adverse effect of chromium poisoning. The present study investigated the potential renoprotective effect of lactoferrin (Lf) against potassium dichromate (PDC)-induced acute kidney injury (AKI) in rats. Beside, because previous studies suggest that interlukin-18 (IL-18) and insulin-like growth factor-1 (IGF-1) play important roles in promoting kidney damage, the present work aimed to evaluate the involvement of these two cytokines in PDC model of AKI and in the potential renoprotective effect of lactoferrin. Adult male albino Wistar rats were pretreated with Lf (200mg/kg/day, p.o.) or (300mg/kg/day, p.o.); the doses that are usually used in the experiment studies, for 14 days followed by a single dose of PDC (15mg/kg, s.c.). PDC caused significant increase in serum urea, creatinine, and total protein levels. This was accompanied with decreased renal glutathione content, and increased renal malondialdehyde, IL-18, IL-4, nuclear factor kappa B (NFκB), IGF-1, and the phosphorylated form of forkhead box protein O1 (FoxO1) levels. Moreover, normal expression IFN-γ mRNA and enhanced expression of TNF-α mRNA was demonstrated in renal tissues. Histopathological investigations provoked deleterious changes in the renal tissues. Tubular epithelial hyperplasia and apoptosis were demonstrated immunohistochemically by positive proliferating cell nuclear antigen (PCNA), Bax, and Caspase-3 expression, respectively. Pretreatment of rats with Lf in both doses significantly corrected all previously mentioned PDC-induced changes with no significant difference between both doses. In conclusion, the findings of the present study demonstrated the involvement of oxidative stress, inflammatory reactions, tubular hyperplasia and apoptosis in PDC-induced AKI. It suggested a role of IL-18 through stimulation of IL-4-induced inflammatory pathway, and IGF-1 through triggering FoxO1

    Peripheral artery disease (PAD) typically refers to lower limb vessel ischemia caused by atherosclerotic stenosis of lower extremity arteries. IL18 is a pleiotropic pro-inflammatory cytokine reported to function as an inflammatory biomarker in cardiovascular diseases. IL18 activity is balanced by high-affinity naturally occurring IL18-binding protein (IL18BP). This study aimed to determine whether IL18, IL18 BP mRNA levels and -137 G/C (rs187238) polymorphism, which was previously associated with IL18 gene transcriptional activity, were associated with PAD etiology. IL18, IL18BP mRNA levels from peripheral blood mononuclear cells and -137 G/C (rs187238) polymorphism were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and RT-PCR, respectively, in 55 PAD patients (26 aorta-iliac, 29 femoro-popliteal) and 61 disease-free controls. IL18 mRNA levels were increased in PAD patients compared with healthy controls (p = 0.09); however, did not reach a statistical significant level, also did not significantly differ between aorta-iliac and femoro-popliteal occlusive PAD subgroups (p = 0.285). However, IL18BP mRNA levels were significantly lower in PAD group compared with controls (p triglycerides and LDL cholesterol levels in PAD patients (p = 0.003, p = 0.014, respectively). HDL cholesterol levels were negatively correlated with IL18 mRNA levels in controls (p = 0.05). This report is a preliminary study to show an association between IL18, IL18BP mRNA levels and PAD and suggests that the IL18 gene may have a significant relationship with triglyceride and LDL cholesterol levels in PAD patients.

    Colorectal cancer (CRC) is a common malignancy worldwide, and chronic inflammation is a risk factor for CRC. In this study, we carried out a cohort study among the Japanese atomic bomb (A-bomb) survivor population to investigate any association between immune- and inflammation-related gene polymorphisms and CRC. We examined the effects of six single-nucleotide polymorphisms of CD14 and IL18 on relative risks (RRs) of CRC. Results showed that RRs of CRC, overall and by anatomic subsite, significantly increased with increasing radiation dose. The CD14-911A/A genotype showed statistically significant higher risks for all CRC and distal CRC compared with the other two genotypes. In addition, the IL18-137 G/G genotype showed statistically significant higher risks for proximal colon cancer compared with the other two genotypes. In phenotype-genotype analyses, the CD14-911A/A genotype presented significantly higher levels of membrane and soluble CD14 compared with the other two genotypes, and the IL18-137 G/G genotype tended to be lower levels of plasma interleukin (IL)-18 compared with the other two genotypes. These results suggest the potential involvement of a CD14-mediated inflammatory response in the development of distal CRC and an IL18-mediated inflammatory response in the development of proximal colon cancer among A-bomb survivors.

    Leptin, adiponectin and IL18 are adipokines related with obesity, insulin resistance and dyslipidemia in the general population. Treated HIV-1-infected patients with lipodystrophy may develop insulin resistance and proatherogenic dyslipidemia. We assessed the relationship between plasma adipokine levels, adipokine genetics, lipodystrophy and metabolic disturbances. Plasma leptin, adiponectin and IL18 levels were assessed in 446 individuals: 282 HIV-1-infected patients treated with antiretroviral drugs (132 with lipodystrophy and 150 without) and 164 uninfected controls (UC). The LEP2410A>G, LEPRQ223R, ADIPQ276G>T, ADIPOR2-Intron5A>G and IL18-607C>A polymorphisms were validated by sequencing. Leptin levels were higher in UC than in HIV-1-infected, either with or without lipodystrophy (plipodystrophy compared with those without lipodystrophy (p=0.006). In patients with lipodystrophy, leptin had a positive correlation with insulin and with HOMA-IR. Adiponectin levels were non-significantly different in UC and HIV-1-infected patients. Patients with lipodystrophy had lower adiponectin levels than non-lipodystrophy subjects (plipodystrophy, adiponectin was negatively correlated with insulin, HOMA-IR and triglycerides. Plasma IL18 levels were higher in HIV-1-infected patients compared with UC (plipodystrophy. In patients with lipodystrophy there was a negative correlation between IL18 levels and LDLc. Genetic analyses indicated no significant associations with lipodystrophy nor with insulin resistance or with lipid abnormalities. In conclusion, HIV-1-infected patients have reduced plasma leptin levels. This reduction is magnified in patients with lipodystrophy whose adiponectin levels were lower than that of non-lipodystrophy subjects. Plasma IL18 levels are increased in infected patients irrespective of the presence of lipodystrophy. The polymorphisms assessed are not associated with lipodystrophy or metabolic disturbances in treated HIV-1-infected patients.

    Keratinocytes (KCs) play a key role in all phases of skin sensitization. We recently identified interleukin-18 (IL-18) production as useful end point for determination of contact sensitization potential of low molecular weight chemicals. The aim of this study was to identify genes involved in skin sensitizer-induced inflammasome activation and to establish their role in IL-18 production. For gene expression analysis, cells were treated for 6 h with p-phenylenediamine (PPD) as reference contact allergen; total RNA was extracted and examined with a commercially available Inflammasome Polymerase Chain Reaction (PCR) array. Among genes induced, NLRP12 (Nod-like receptor P12) was selected for further investigation. NLRP12 promoter region contains Blimp-1 (B-lymphocyte-induced maturation protein-1)/PRDM1 binding site, and from the literature, it is reported that Blimp-1 reduces NLRP12 activity and expression in monocytes/macrophages. Their expression and role in KCs are currently unknown. To confirm NLRP12 expression and to investigate its relationship with Blimp-1, cells were exposed for different times (3, 6 and 24 h) to the extreme sensitizer 2,4-dinitrochlorobenzene (DNCB) and the strong sensitizer PPD. Allergens were able to induce both genes, however, with different kinetic, with DNCB more rapidly upregulating Blimp-1 and inducing IL-18 production, compared to PPD. NLRP12 and Blimp-1 expression appeared to be inversely correlated: Blimp-1 silencing resulted in increased NLRP12 expression and reduced contact allergen-induced IL-18 production. Overall results indicate that contact allergens of different potency differently modulate Blimp-1/NLRP12 expression, with strong allergen more rapidly downregulating NLRP12, thus more rapidly inducing IL-18 production. Data confirm that also in KCs, NLRP12 has an inhibitory effect on inflammasome activation assessed by IL-18 maturation.

  10. Distinct licensing of IL-18 and IL-1β secretion in response to NLRP3 inflammasome activation.

    Directory of Open Access Journals (Sweden)

    Rebecca L Schmidt

    Full Text Available Inflammasome activation permits processing of interleukins (IL-1β and 18 and elicits cell death (pyroptosis. Whether these responses are independently licensed or are "hard-wired" consequences of caspase-1 (casp1 activity has not been clear. Here, we show that that each of these responses is independently regulated following activation of NLRP3 inflammasomes by a "non-canonical" stimulus, the secreted Listeria monocytogenes (Lm p60 protein. Primed murine dendritic cells (DCs responded to p60 stimulation with reactive oxygen species (ROS production and secretion of IL-1β and IL-18 but not pyroptosis. Inhibitors of ROS production inhibited secretion of IL-1β, but did not impair IL-18 secretion. Furthermore, DCs from caspase-11 (casp11-deficient 129S6 mice failed to secrete IL-1β in response to p60 but were fully responsive for IL-18 secretion. These findings reveal that there are distinct licensing requirements for processing of IL-18 versus IL-1β by NLRP3 inflammasomes.

    A homologue of interleukin 18 has been identified from rainbow trout, Oncorhynchus mykiss. The trout IL-18 gene spans 3.7 kb and consists of six exons and five introns, sharing the same gene organization with its human counterpart. The putative translated protein is 199 amino acids in length with no predicted signal peptide. Analysis of the multiple sequence alignment reveals a conserved ICE cut site, resulting in a mature peptide of 162 amino acids. The trout IL-18 shares 41-45% similarity with known IL-18 molecules and contains an IL-1 family signature motif. It is constitutively expressed in a wide range of tissues including brain, gill, gut, heart, kidney, liver, muscle, skin and spleen. Transcription is not modulated by lipopolysaccharide, poly(I:C) or trout recombinant IL-1beta in primary head kidney leucocyte cultures and RTS-11 cells, a macrophage cell line. However, expression is downregulated by lipopolysaccharide and rIL-1beta in RTG-2 cells, a fibroblast-like cell line. An alternatively spliced form of IL-18 mRNA has also been found and translates into a 182 amino acid protein with a 17 amino acid deletion in the precursor region of the authentic form. This alternatively spliced form is also widely expressed although much lower than the authentic form. Interestingly, its expression is upregulated by lipopolysaccharide and poly(I:C), but is not affected by rIL-1beta in RTG-2 cells. The present study suggests that alternative splicing may play an important role in regulating IL-18 activities in rainbow trout.

    Interleukin-18 (IL-18) is a pleiotropic cytokine involved in the development of T helper type 1 (Thl) cells, and it plays important roles in regulation of both the innate and acquired immune responses. The aim of this study was to elucidate whether the reversible histone acetylation/ deacetylation modification participates in the regulation of IL-18 transcription expression. The transcription coactivator p300 containing the histone acetyltransferase (HAT) activity, and the histone deacetylase 3 (HDAC3) were used in this study to analyze the effect of this modification in the regulation of mouse IL-18 gene. The results demonstrate that transfection of p300-expression plasmid promotes the endogenous IL-18 mRNA synthesis in J774 cells, and stimulates the activation of IL-18 promoter. It has been found that this stimulating effect of p300 was reversed by HDAC3, indicating the involvement of the reversible histone acetylation/deacetylation modification in IL-18 regulation. Furthermore, the data show that the HAT activity of p300 was essential to its function in activating IL-18 promoter. In addition, p300 was shown to be able to work synergistically with the transcription factor c-Fos on activation of IL-18 promoter and this effect could also be impaired by HDAC3. Results presented in this paper indicate that the reversible histone acetylation/deacetylation modification plays an important role in the transcriptional regulation of IL-18.

Here we show that murine intestinal CD4+ T cells express high levels of IL-18Rα and provide evidence that IL-18Rα expression is induced...... on these cells subsequent to their entry into the intestinal mucosa. Using the CD45RBhi T-cell transfer colitis model, we show that IL-18Rα is expressed on IFN-γ+, IL-17+ and IL-17+IFN-γ+ effector CD4+ T cells in the inflamed colonic lamina propria (cLP) and mesenteric lymph node (MLN) and is required...... for the optimal generation and/or maintenance of IFN-γ-producing cells in the cLP. In the steady state and during colitis, TCR-independent cytokine-induced IFN-γ and IL-17 production by intestinal CD4+ T cells was largely IL-18Rα−dependent. Despite these findings however, IL-18Rα−deficient CD4+ T cells induced...

  15. Identification of a truncated splice variant of IL-18 receptor alpha in the human and rat, with evidence of wider evolutionary conservation

    Full Text Available Interleukin-18 (IL-18 is a pro-inflammatory cytokine which stimulates activation of the nuclear factor kappa beta (NF-κB pathway via interaction with the IL-18 receptor. The receptor itself is formed from a dimer of two subunits, with the ligand-binding IL-18Rα subunit being encoded by the IL18R1 gene. A splice variant of murine IL18r1, which has been previously described, is formed by transcription of an unspliced intron (forming a ‘type II’ IL18r1 transcript and is predicted to encode a receptor with a truncated intracellular domain lacking the capacity to generate downstream signalling. In order to examine the relevance of this finding to human IL-18 function, we assessed the presence of a homologous transcript by reverse transcription-polymerase chain reaction (RT-PCR in the human and rat as another common laboratory animal. We present evidence for type II IL18R1 transcripts in both species. While the mouse and rat transcripts are predicted to encode a truncated receptor with a novel 5 amino acid C-terminal domain, the human sequence is predicted to encode a truncated protein with a novel 22 amino acid sequence bearing resemblance to the ‘Box 1’ motif of the Toll/interleukin-1 receptor (TIR domain, in a similar fashion to the inhibitory interleukin-1 receptor 2. Given that transcripts from these three species are all formed by inclusion of homologous unspliced intronic regions, an analysis of homologous introns across a wider array of 33 species with available IL18R1 gene records was performed, which suggests similar transcripts may encode truncated type II IL-18Rα subunits in other species. This splice variant may represent a conserved evolutionary mechanism for regulating IL-18 activity.

    Full Text Available Abstract Background In human neonatal high pressure hydrocephalus (HPHC, diffuse white matter injury and gliosis predispose to poor neuro-developmental outcome. The underlying mechanism for diffuse white matter damage in neonatal HPHC is still unclear. Analogous to inflammatory white matter damage after neonatal hypoxemia/ischemia, we hypothesized that pro-inflammatory cytokines could be involved in neonatal HPHC. If so, early anti-inflammatory therapy could ameliorate white matter damage in HPHC, before irreversible apoptosis has occurred. In HPHC and control neonates, we therefore aimed to compare cerebrospinal fluid (CSF concentrations of IL18, IFNγ and sFasL (interleukin 18, interferon gamma and apoptosis marker soluble-Fas ligand, respectively. Methods In neonatal HPHC (n = 30 and controls (n = 15, we compared CSF concentrations of IL18, IFNγ and sFasL using sandwich ELISA. HPHC was grouped according to etiology: spina bifida aperta (n = 20, aqueduct stenosis (n = 4, and fetal intra-cerebral haemorrhage (n = 6. Neonatal control CSF was derived from otherwise healthy neonates (n = 15, who underwent lumbar puncture for exclusion of meningitis. Results In all three HPHC groups, CSF IL18 concentrations were significantly higher than control values, and the fetal intracranial haemorrhage group was significantly higher than SBA group. Similarly, in all HPHC groups CSF-IFNγ concentrations significantly exceeded the control group. In both HPHC and control neonates, CSF FasL concentrations remained within the range of reference values. Conclusion Independent of the pathogenesis, neonatal HPHC is associated with the activation of the pro-inflammatory cytokines (IL-18 and IFNγ in the CSF, whereas CSF apoptosis biomarkers (sFasL were unchanged. This suggests that anti-inflammatory treatment (in addition to shunting could be helpful to preserve cerebral white matter.

  19. TRAM is involved in IL-18 signaling and functions as a sorting adaptor for MyD88.

    Directory of Open Access Journals (Sweden)

    Hidenori Ohnishi

    Full Text Available MyD88, a Toll/interleukin-1 receptor homology (TIR domain-containing adaptor protein, mediates signals from the Toll-like receptors (TLR or IL-1/IL-18 receptors to downstream kinases. In MyD88-dependent TLR4 signaling, the function of MyD88 is enhanced by another TIR domain-containing adaptor, Mal/TIRAP, which brings MyD88 to the plasma membrane and promotes its interaction with the cytosolic region of TLR4. Hence, Mal is recognized as the "sorting adaptor" for MyD88. In this study, a direct interaction between MyD88-TIR and another membrane-sorting adaptor, TRAM/TICAM-2, was demonstrated in vitro. Cell-based assays including RNA interference experiments and TRAM deficient mice revealed that the interplay between MyD88 and TRAM in cells is important in mediating IL-18 signal transduction. Live cell imaging further demonstrated the co-localized accumulation of MyD88 and TRAM in the membrane regions in HEK293 cells. These findings suggest that TRAM serves as the sorting adaptor for MyD88 in IL-18 signaling, which then facilitates the signal transduction. The binding sites for TRAM are located in the TIR domain of MyD88 and actually overlap with the binding sites for Mal. MyD88, the multifunctional signaling adaptor that works together with most of the TLR members and with the IL-1/IL-18 receptors, can interact with two distinct sorting adaptors, TRAM and Mal, in a conserved manner in a distinct context.

  20. Involvement of IL-18 in the expansion of unique hepatic T cells with unconventional cytokine profiles during Schistosoma mansoni infection.

    Keishi Adachi

    Full Text Available Infection with schistosomes invokes severe fibrotic granulomatous responses in the liver of the host. Schistosoma mansoni infection induces dramatic fluctuations in Th1 or Th2 cytokine responses systemically; Th1 reactions are provoked in the early phase, whilst Th2 responses become dominant after oviposition begins. In the liver, various unique immune cells distinct from those of conventional immune competent organs or tissues exist, resulting in a unique immunological environment. Recently, we demonstrated that S. mansoni infection induces unique CD4+ T cell populations exhibiting unconventional cytokine profiles in the liver of mice during the period between Th1- and Th2-phases, which we term the transition phase. They produce both IFN-γ and IL-4 or both IFN-γ and IL-13 simultaneously. Moreover, T cells secreting triple cytokines IFN-γ, IL-13 and IL-4 were also induced. We term these cells Multiple Cytokine Producing Hepatic T cells (MCPHT cells. During the transition phase, when MCPHT cells increase, IL-18 secretion was up-regulated in the liver and sera. In S. mansoni-infected IL-18-deficient mice, expansion of MCPHT cells was curtailed. Thus our data suggest that IL-18 produced during S. mansoni infection play a role in the expansion of MCPHT cells.

    Full Text Available Salmonella Typhimurium (S.Tm is a common cause of self-limiting diarrhea. The mucosal inflammation is thought to arise from a standoff between the pathogen's virulence factors and the host's mucosal innate immune defenses, particularly the mucosal NAIP/NLRC4 inflammasome. However, it had remained unclear how this switches the gut from homeostasis to inflammation. This was studied using the streptomycin mouse model. S.Tm infections in knockout mice, cytokine inhibition and -injection experiments revealed that caspase-1 (not -11 dependent IL-18 is pivotal for inducing acute inflammation. IL-18 boosted NK cell chemoattractants and enhanced the NK cells' migratory capacity, thus promoting mucosal accumulation of mature, activated NK cells. NK cell depletion and Prf-/- ablation (but not granulocyte-depletion or T-cell deficiency delayed tissue inflammation. Our data suggest an NK cell perforin response as one limiting factor in mounting gut mucosal inflammation. Thus, IL-18-elicited NK cell perforin responses seem to be critical for coordinating mucosal inflammation during early infection, when S.Tm strongly relies on virulence factors detectable by the inflammasome. This may have broad relevance for mucosal defense against microbial pathogens.

    2001-01-01

    Objective: Interleukin 18 (IL-18) is a strong activator of NK cells and promotes the generation of IL-2, IFN-g, and GM-CSF. In the present study, we constructed adenovirus encoding IL-18 gene (AdIL-18), and observed the biological characteristics of IL-18 gene-modified murine colorectal adenocarcinoma cell (CT26) in vivo and in vitro. Methods: Gene modification was mediated by adenovirus. The proliferation of the cells was determined by MTT and IL-18 was assayed by ELISA. The cytotoxicity of NK and CTL was detected by four-hour 51Cr release assay. Results: IL-18 gene modification had no effect on the proliferation and morphology of CT-26 cells in vitro, but the growth of IL-18-modified CT26 cells was obviously inhibited in vivo. In addition, although IL-18-modified CT26 cells could form tumor nodules in vivo as well as LacZ-modified CT26 cells or wild-type CT26 cells, the mean survival time of the mice inoculated with IL-18-modified CT26 cells was significantly prolonged as compared with that of control groups. Thus, the anti-tumor immune responses were induced in the group of mice inoculated with IL-18-modified CT26 cells, which might be related to the activation of NK cells and CTL. However, all the three groups ultimately died of tumor.free facility for all experiments. CT26, Yac-1 and 293 cells were from the American Type Culture Collection (ATCC, Manassas, VA). All cell lines were cultured in RPMI1640 (GIBCO-BRL, Grandisland, NY) supple-mented with penicillin (100 units/ml), streptomycin (100 mg/ml), 2-mercaptoethanol (5′10-5 M), and 10% FCS (GIBCO-BRL) at 37℃ in a humidified atmosphere of 5% CO2 in air.

    Full Text Available OBJECTIVE: To investigate the link between serum interleukin-18 (IL-18 levels and physical activity in Japanese men. METHODS: A total of 81 men (45.7±17.6 years old was enrolled in this cross-sectional investigation study. We assessed anthropometric and body composition parameters. Serum IL-18 levels, physical activity by uniaxial accelerometers, peak oxygen uptake and metabolic risk parameters were also evaluated. RESULTS: Serum IL-18 levels were 179.4±84.7 pg/mL. Physical activity evaluated by Σ[metabolic equivalents × h per week (METs⋅h/w]was significantly and negatively correlated with serum IL-18 levels (r = -0.252, p = 0.0235. These associations remained even after adjusting for age, peak oxygen uptake and other confounding factors. CONCLUSION: Serum IL-18 levels were closely associated with physical activity independent of peak oxygen uptake in Japanese men.

    The IL-1 family members IL-1ß, IL-18, and IL-33 are potent cytokines in relationship to amplifying the CD4(+) T cell cytokine production. To evaluate their impact on in vitro-differentiated human Th1 and Th2 cultures, such cultures were established from naive T cells, purified from healthy blood...... donors, and reactivated in the presence of IL-1ß, IL-18, or IL-33. Interestingly, we observe modifying responses in Th1 and Th2 cultures induced by IL-18 or IL-33 but not by IL-1ß, both contributing to amplify production of IL-5, IL-13, and IFN-¿. IL-18 or IL-33 stimulation of Th1 cultures resulted...... in increased IFN-¿ and IL-13 production concurrent with reduced IL-10 gene transcription and secretion even though Th1 cultures, in contrast to IL-18Ra, had low ST2L expression.

    Full Text Available  Introduction:Interleukin-18 (IL-18 is a pleiotropic cytokine playing an important role as a modulator of immune responses, found to play a role in pathogenesis of numerous inflammatory-associated disorders. In the present study a potential association between 7 common single-nucleotide polymorphisms (SNPs spanning the whole IL18 gene, gene expression and the release of IL-18 from the stimulated peripheral blood mononuclear cells (PBMCs was investigated.Materials/Methods:PBMCs were isolated from peripheral blood of 29 healthy volunteers, genotyped for the presence of IL18 SNPs: rs1946518: A>C, rs187238: G>C, rs360718: A>C, rs360722: C>T, rs360721: C>G, rs549908: T>G, and rs5744292: A>G. IL-18 concentration and IL18 mRNA levels were investigated after incubation of cells for 48 h with different stimulants (PHA, LPS, and anti-CD3/CD28 antibodies.Results:After treatment with LPS and antibodies IL-18 concentrations were significantly lower in rs1946518AA homozygotes than in C allele carriers. When differences in IL18 mRNA levels between non-stimulated and stimulated cells were analyzed, significantly decreased gene expression was noted in rs1946518 AA homozygotes (as compared with C allele carriers in samples treated with PHA and LPS. Similar trends were observed in the case of rs187238 SNP; however, the differences reached statistical significance only after PHA treatment.Conclusions:Our study supports the role of rs1946518 (-607A>C and rs187238 (-137G>C SNPs as genetic determinants of the observed variability in IL18 expression.

  10. Saturated fatty acids activate caspase-4/5 in human monocytes, triggering IL-1β and IL-18 release.

    Obesity is associated with metabolic tissue infiltration by monocyte-derived macrophages. Saturated fatty acids contribute to proinflammatory gene induction in tissue-embedded immune cells. However, it is unknown how circulating monocytes, the macrophage precursors, react to high-fat environments. In macrophages, saturated fatty acids activate inflammatory pathways and, notably, prime caspase-associated inflammasomes. Inflammasome-activated IL-1β contributes to type 2 diabetes. We hypothesized that 1) human monocytes from obese patients show caspase activation, and 2) fatty acids trigger this response and consequent release of IL-1β/IL-18. Human peripheral blood monocytes were sorted by flow cytometry, and caspase activity was measured with a FLICA dye-based assay. Blood monocytes from obese individuals exhibited elevated caspase activity. To explore the nature and consequence of this activity, human THP1 monocytes were exposed to saturated or unsaturated fatty acids. Caspase activity was revealed by isoform-specific cleavage and enzymatic activity; cytokine expression/release was measured by qPCR and ELISA. Palmitate, but not palmitoleate, increased caspase activity in parallel to the release of IL-1β and IL-18. Palmitate induced eventual monocyte cell death with features of pyroptosis (an inflammation-linked cell death program involving caspase-4/5), scored through LDH release, vital dye influx, cell volume changes, and nuclear morphology. Notably, selective gene silencing or inhibition of caspase-4/5 reduced palmitate-induced release of IL-1β and IL-18. In summary, monocytes from obese individuals present elevated caspase activity. Mechanistically, palmitate activates a pyroptotic program in monocytes through caspase-4/5, causing inflammatory cytokine release, additional to inflammasomes. These caspases represent potential, novel, therapeutic targets to taper obesity-associated inflammation.

    Allergic reactions occur through the exacerbated induction of a Th2 cell type expression profile and can be prevented by agents favoring a Th1 profile. Bacillus Calmette-Guérin (BCG) is able to induce high IFN-gamma levels and has been shown to decrease experimentally induced allergy. The induction of IFN-gamma is mediated by interleukin (IL)-12 known to be secreted upon mycobacterial infections and can be enhanced by IL-18 acting in synergy with IL-12. We evaluated the ability of a recombinant BCG strain producing IL-18 (rBCG) to modify the Th2 type responses in a murine model of ovalbumin (OVA)-dependent allergic reaction. Mice were injected intraperitoneally or intranasally with OVA at days 0 and 15 and exposed to an OVA aerosol challenge at days 29, 30, 31 and 34. At days 0 and 15, two additional groups of mice received OVA together with 5 x 10(6) colony forming units of either rBCG or nonrecombinant BCG. A time-course analysis of OVA-specific immunoglobulin (Ig)E, IgG1 and IgG2a levels indicated no significant difference between the three groups of mice. However, following in vitro stimulation with OVA, lymph node cells from rBCG-treated mice produced less IL-5 and more IFN-gamma than those of mice injected with nonrecombinant BCG. In addition, 48 h after the last OVA challenge, a strong reduction of bronchoalveolar eosinophilia was found in the rBCG-injected mice compared to the nontreated or nonrecombinant BCG-treated groups. These results indicate that the production of IL-18 by rBCG may enhance the immunomodulatory properties of BCG that suppress pulmonary Th2 responses and, in particular, decrease airway eosinophilia.

    Highlights: • DSC reveals modified thermal behavior of blood serum from schizophrenic patients. • The high-abundance portion of the serum proteome is thermally stabilized in Sz. • The Sz plasma thermograms are classified in four distinct calorimetric groups. • The effectiveness of drug treatment correlates with the plasma thermodynamic behavior. - Abstract: Schizophrenia (Sz) is a multifactorial mental disorder with high frequency. Due to its chronic and relapsing nature there is a strong need for biomarkers for early psychosis detection and objective evaluation of drug (usually antipsychotics) treatment effect. Here differential scanning calorimetry (DSC) is applied to thermodynamically characterize the blood serum proteome of paranoid schizophrenia patients on routine antipsychotic treatment in comparison to healthy controls. DSC revealed significant modifications in the thermodynamic behavior of blood sera from Sz patients, the overall thermal profile being changed in all Sz cases under study. The calorimetric profiles were classified in four distinct groups, reflecting different thermal stabilization of the high-abundance portion of the serum proteome. The observed positive (thermograms becoming closer to the healthy profile) or negative (thermograms deviating stronger from the healthy profile) proteome thermal stability switches and the Sz thermograms persistence in patients’ follow-up corresponded well with the effect of drug treatment.

    Major depressive disorder (MDD) and schizophrenia are associated with inflammatory processes. Studies have shown that these disorders exhibit increase in the level of one or more proinflammatory markers. However, these studies did not exclude patients with obvious inflammation (i.e., CRP>6mg/L). Therefore, a comprehensive study should include those inflammatory disorders. In the present study, the inflammatory natures of MDD and schizophrenia were investigated. To achieve this goal, serum levels of interleukin-6 (IL-6), interleukin-18 (IL-18), tumor necrosis factor alpha (TNFα), and soluble interleukin 2 receptor (sIL-2R) in depressed and schizophrenic patients were obtained and compared with those of the control group. Results showed a significant increase (pschizophrenia group showed higher levels of the inflammatory markers than MDD and control groups. The current study concluded that the immunological response in the MDD and schizophrenic patients groups was significantly stimulated. These disorders may be considered an inflammatory disorder because of elevated levels of proinflammatory cytokines in spite of lacking an overt inflammation. Furthermore results of this study suggested the possibility of the use of anti-inflammatory drugs as adjuvant therapy in schizophrenic and depressive disorders. Copyright © 2015 Elsevier B.V.

    Patients with differentiated thyroid cancer (DTC) usually have an excellent prognosis. Following surgical and radioiodine treatment to remove the cancer cells and suppressive doses of levothyroxine, long-term follow-up, including measurement of serum thyroglobulin (Tg) using a sensitive assay is required to detect recurrence. To interpret Tg results clinicians need to know the corresponding serum TSH concentration, have an appreciation of the clearance of Tg from patient serum following various interventions and the limitations of its measurement. The limitations of Tg immunoassay are well described and include potential interference from TgAb. For the majority of patients with DTC who are TgAb-negative, Tg measurement remains the most useful method of follow-up. For the TgAb-positive minority, interference and the possibility of producing erroneous results is a concern. Some assays are less badly affected than others and laboratories are advised to choose their assays carefully. Laboratories have sought to identify interferences using measurement of TgAb, lack of concordance between RIAs and immunometric assays and recovery of added Tg. More recently LC-MSMS assays to quantify Tg have been developed. They are not currently as sensitive as Tg immunoassays and it is likely these assays will, like immunoassays, be limited by Tg heterogeneity and standardization issues, although initial evaluations indicate that they may have value in the clinical setting as a second line test in antibody-positive DTC patients in whom Tg is unmeasurable by immunoassay.

    Control of the circulation of H9N2 avian influenza virus (AIV) is a major concern for both animal and public health, and H9N2 AIV poses a major threat to the chicken industry worldwide. Here, we developed a recombinant fowlpox virus (rFPV-HA) expressing the haemagglutinin (HA) gene of the A/CH/JY/1/05 (H9N2) influenza virus and a recombinant fowlpox virus (rFPV-HA/IL18) expressing the HA gene and chicken interleukin-18 (IL-18) gene. Recombinant plasmid pSY-HA/IL18 was constructed by cloning chicken IL-18 expression cassette into recombinant plasmid pSY-HA containing the HA gene. Two rFPVs were generated by transfecting two recombinant plasmids into the chicken embryo fibroblast cells pre-infected with S-FPV-017, and assessed for their immunological efficacy on one-day-old White Leghorn specific-pathogen-free chickens challenged with the A/CH/JY/1/05 (H9N2) strain. There was a significant difference in HI antibody levels (P<0.05) elicited by either rFPV-HA or rFPV-HA/IL18. The level of splenocyte proliferation response in the rFPV-HA/IL18-vaccinated group was significantly higher (P<0.05) than that in the rFPV-HA group. After challenge with 10(6.5)ELD(50) H9N2 AIV 43days after immunization, rFPVs vaccinated groups could prevent virus shedding and replication in multiple organs in response to H9N2 AIV infection, and rFPV-HA/IL18 vaccinated group had better inhibition of viruses than rFPV-HA vaccinated group. Our results show that the protective efficacy of the rFPV-HA vaccine could be enhanced significantly by simultaneous expression of IL-18.

    In order to investigate the feasibility of serum creatine kinase (CK) and blood urea nitrogen (BUN) in monitoring pre-competition training of badminton athletes, the pre-competition training load of 20 badminton athletes was studied, and serum CK and BUN were determined before, immediate and next morning after training. The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L (P<0.05). After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L (P<0.05). BUN contents were increased by 0.83 mmol/L on average with the difference being not significant (P>0.05). After intermittent training, there was significant difference in the average increased levels of serum CK in athletes (P<0.05). There was significant difference before and after regulation of training (P<0.05). The increased levels of BUN were 0.78 mmol/L without significant difference (P>0.05). It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.

    Infectious laryngotracheitis virus (ILTV) is an alphaherpesvirus that causes severe and economically significant respiratory disease in poultry worldwide. Herein, the immunogenicity of two recombinant fowlpox viruses (rFPV-gB and rFPV-gB/IL18) containing ILTV glycoprotein B (gB) and chicken interleukin-18 (IL-18) were investigated in a challenge model. One-day-old specific-pathogen-free chickens were vaccinated by wing-web puncture with the two rFPVs and challenged with the virulent ILTV CG strain. There were differences in antibody levels elicited by either rFPV-gB/IL18 or rFPV-gB as determined using ELISA. The ratios of CD4(+) to CD8(+) in chickens immunized with rFPV-gB/IL18 were higher (P chickens immunized with rFPV-gB/IL18 were protected (10/10), whereas only eight of 10 of the chickens immunized with the rFPV-gB were protected. The results showed that the protective efficacy of the rFPV-gB vaccine could be enhanced by simultaneous expression of chicken IL-18.

    The feasibility of using hollow core photonic crystal fiber (HC-PCF) in conjunction with Raman spectroscopy has been explored for real time monitoring of heparin concentration in serum. Heparin is an important blood anti-coagulant whose precise monitoring and controlling in patients undergoing cardiac surgery and dialysis is of utmost importance. Our method of heparin monitoring offers a novel alternative to existing clinical procedures in terms of accuracy, response time and sample volume. The optical design configuration simply involves a 785-nm laser diode whose light is coupled into HC-PCF filled with heparin-serum mixtures. By non-selectively filling HC-PCF, a strong modal field overlap is obtained. Consequently, an enhanced Raman signal (>90 times) is obtained from various heparin-serum mixtures filled HC-PCFs compared to its bulk counterpart (cuvette). The present scheme has the potential to serve as a `generic biosensing tool' for diagnosing a wide range of biological samples.

    Full Text Available BACKGROUND: Modified Vaccinia Ankara (MVA is an attenuated strain of Vaccinia virus (VACV currently employed in many clinical trials against HIV/AIDS and other diseases. MVA still retains genes involved in host immune response evasion, enabling its optimization by removing some of them. The aim of this study was to evaluate cellular immune responses (CIR induced by an IL-18 binding protein gene (C12L deleted vector (MVAΔC12L. METHODOLOGY/PRINCIPAL FINDINGS: BALB/c and C57BL/6 mice were immunized with different doses of MVAΔC12L or MVA wild type (MVAwt, then CIR to VACV epitopes in immunogenic proteins were evaluated in spleen and draining lymph nodes at acute and memory phases (7 and 40 days post-immunization respectively. Compared with parental MVAwt, MVAΔC12L immunization induced a significant increase of two to three-fold in CD8(+ and CD4(+ T-cell responses to different VACV epitopes, with increased percentage of anti-VACV cytotoxic CD8(+ T-cells (CD107a/b(+ during the acute phase of the response. Importantly, the immunogenicity enhancement was also observed after MVAΔC12L inoculation with different viral doses and by distinct routes (systemic and mucosal. Potentiation of MVA's CIR was also observed during the memory phase, in correlation with a higher protection against an intranasal challenge with VACV WR. Of note, we could also show a significant increase in the CIR against HIV antigens such as Env, Gag, Pol and Nef from different subtypes expressed from two recombinants of MVAΔC12L during heterologous DNA prime/MVA boost vaccination regimens. CONCLUSIONS/SIGNIFICANCE: This study demonstrates the relevance of IL-18 bp contribution in the immune response evasion during MVA infection. Our findings clearly show that the deletion of the viral IL-18 bp gene is an effective approach to increase MVA vaccine efficacy, as immunogenicity improvements were observed against vector antigens and more importantly to HIV antigens.

    2014-12-01

    Full Text Available Background: A molecular approach to estimation of local inflammatory response associated with dysbiotic conditions of the vagina is reported. This approach is based on immune response gene transcription levels measured by qPCR assay. Methods and Results: qPCR analysis of 24 immune response gene transcripts in vaginal smears was performed for 215 women with vaginitis and 95 healthy controls. The data were sorted by comparison to local inflammatory response profiles assessed by conventional methods. The local inflammatory response in the vagina is found to correlate with TNF-alpha, IL18, TLR4, and GATA3 transcript levels. Sensitivity and specificity of the approach, as validated in accordance with conventional clinical examination results, are 94.9% and 93.7%, respectively. Conclusions: The noninvasive diagnostic approach to vaginal pathology based solely on its molecular characterization may prove to be clinically relevant.

    Skeletal muscle is now recognized as an endocrine organ with the capacity to produce signal peptides in response to muscle contractions. Here we demonstrate that resting healthy human muscles express cytokines in a fiber type specific manner. Human muscle biopsies from seven healthy young males...... were obtained from m. triceps, m. quadriceps vastus lateralis and m. soleus. Type I fibers contributed (mean +/- SE) 24.0 +/- 2.5% in triceps of total fibers, 51.3 +/- 2.4% in vastus and 84.9 +/- 22% in soleus. As expected, differences in the fiber type composition were accompanied by marked...... differences between the three muscles with regard to MHC I and MHC IIa mRNA expression. Immunohistochemistry demonstrated that tumor necrosis factor (TNF)-alpha and interleukin (IL)-18 were solely expressed by type II fibers, whereas the expression of IL-6 was more prominent in type I compared to type II...

    We report in this manuscript, the use of direct ammonium persulfate-enhanced chemiluminescence (CL) imaging, to monitor changes to measure serum salbutamol concentration in subjects of different haptoglobin (Hp) phenotypes at different dosing time. It was noted that CL generated from Hp was decreased due to salbutamol's reducibility, which was used for monitoring salbutamol concentration in serum. The serum from the subjects treated by oral administration of salbutamol, was collected at different dosing time and was separated by polyacrylamide gel electrophoresis (PAGE) prior to the CL detection. According to CL images, samples were separated into three groups based on the Hp phenotypes. The curves of CL signal intensity versus time were obtained for each group, and we demonstrated that there were more significant variables on binding ability between groups. The maximum salbutamol concentration in the serum appeared after 4h, which was in agreement with the literature. In addition, the binding constants of salbutamol to Hp were determined by a fluorescence-based method, whose results were in agreement with the phenomenon of the greater salbutamol metabolism rate for Group Hp 1-1 than Group Hp 2-2. The presented method can monitor changes of salbutamol concentration in serum directly, making the procedures much simple, convenient, rapid and has the property of lower cost. It provided us with excellent reference information for the individual dosage regimen of different Hp groups, which hopefully could become a potential method for further pharmaceutical research.

    To investigate the effect of TGF-β1 on the expressions of IL-12, IL-15, IL-18, IL-4 and IL-10 in heart transplantation rejection in rats, a model of rat cervical heterotopic heart transplanta-tion was set up and the model rats were randomly divided into three groups: control group, transplant group and TGF-β1 group. The mRNA expression levels of IL-12, IL-15, IL-18, IL-4 and IL-10 were determined by RT-PCR at the 5th day after the transplantation. The mRNA expression levels of IL-12,IL-15, IL-18 were increased obviously and those of IL-4, IL-10 were significantly decreased in the transplant group as compared with the control group (P<0.01). In the TGF-β1 group, the mRNA ex-pression levels of IL-12, IL-15, IL-18 were significantly decreased and those of IL-4, IL-10 were sig-nificantly increased as compared with the transplant group (P<0.01). The immunosuppressive effect of TGF-β1 on heart transplantation rejection was related to its inhibition of the expressions of Th1-type cytokines (IL-12, IL-15, IL-18 etc) and its promotion of the expressions of Th2-tpye cyto-kines (IL-4, IL-10).

    The usefulness of the serum fructosamine (Fser) to monitor the retrospective glucose concentrations in transitional dairy cows (n=17) was evaluated. In weekly blood samples (3 weeks before to 5 weeks after calving) concentrations of plasma glucose and serum fructosamine, beta-hydroxybutyrate (beta OHB) and total proteins were determined. The observed Fser concentrations (271+/-55 mean value, range 152-423 mumol/l) were within the range reported in the literature, and showed a progressive and significant decrease after calving. Mean plasma glucose concentration was 60.6+/-5.0 (range 39.9-82.2) mg/dl increasing from week 3 before calving to the week of calving and then decreasing during the next 5 weeks of lactation. This decrease was coincident with inverse relationships between plasma glucose and milk yield (P=0.03) and serum beta OHB (P<0.001). Linear regression analysis performed between serum fructosamine and (a) plasma glucose concentration of the same sampling and (b) plasma glucose concentration of 1, 2 and 3 weeks preceding the sampling, did not show significant and systematizing positive correlations. Persistent hypoproteinaemias that could affect the fructosamine concentrations were not found: mean value and range of serum proteins was 6.3+/-1.0 and 4.8-7.8 g/dl, respectively, and no correlation was found between serum proteins and Fser (P=0.26). Results did not support the possibility of retrospective monitoring of the plasma glucose concentration by serum fructosamine in dairy cows in the transition period.

    Skeletal muscle is now recognized as an endocrine organ with the capacity to produce signal peptides in response to muscle contractions. Here we demonstrate that resting healthy human muscles express cytokines in a fiber type specific manner. Human muscle biopsies from seven healthy young males were obtained from m. triceps, m. quadriceps vastus lateralis and m. soleus. Type I fibers contributed (mean +/- SE) 24.0 +/- 2.5% in triceps of total fibers, 51.3 +/- 2.4% in vastus and 84.9 +/- 22% in soleus. As expected, differences in the fiber type composition were accompanied by marked differences between the three muscles with regard to MHC I and MHC IIa mRNA expression. Immunohistochemistry demonstrated that tumor necrosis factor (TNF)-alpha and interleukin (IL)-18 were solely expressed by type II fibers, whereas the expression of IL-6 was more prominent in type I compared to type II fibers. The fiber type specificity was found in triceps, vastus and soleus indicating that the level of daily muscle activity did not influence basal cytokine expression. The specificity of cytokine expression in different muscle fiber types in healthy young males suggests that cytokines may play specific regulatory roles in normal physiology.

    [Objective] To clone the porcine interleukin-18(IL-18) cDNA and explore the immunological effectiveness of porcine IL-18 as an adjuvant of genetic vaccine. [Method] The spleen lymphocytes were isolated from Henan three-way cross-breeding pigs. According to the porcine IL-18 gene in GenBank, a pair of specific primers was designed. The full length cDNA of porcine IL-18 was amplified by RT-PCR. Subsequently, porcine IL-18 cDNA was cloned into pGEM-T vector and sequenced and analyzed. [Result] The porcine IL-18 gene demonstrated an open reading frame of 579 bp encoding an inactive precursor protein with 192 amino acids. The precursor protein had no typical hydrophobic signal peptide and cleaved by interleukin-1 beta (IL-1β) converting enzyme (ICE) in caspase-1 splice site; the porcine mature protein had biological activity. After comparing with other porcine IL-18 genes, the nucleotide sequence homology was over 96% and the deduced amino acid homology was more than 98%. [Conclusion] A full length procine IL-18 gene was gained. It lays the foundation for porcine IL-18 as an adjuvant of genetic vaccine.

    2006-01-01

    AIM: To investigate interleukin-18 (IL-18) in patients with chronic panreatitis (CP). METHODS: We studied 29 patients with CP and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated with 50 mmol/L ethanol, lipopolysaccharide (LPS) (doses 25 g/L, 250 g/L, 2500 g/L) and both agents for 24 h. Levels of IL-18 in the supernatants, and levels of IL-18, IL-12, interferon (IFN)-γ and soluble CD14 in the serum were analysed by ELISA technique. Expression of IL-18 in PBMC was investigated by reverse-transcription (RT)-PCR. IL-18 protein levels in CP tissue and in normal pancreas were studied by ELISA technique. IL-18 levels in PBMC and pancreatic tissue were determined by Westernblot. Immunohistochemistry for pancreatic IL-18 expression was performed. RESULTS: In patients, IL-18 serum levels were significantly enhanced by 76% (mean: 289.9 ± 167.7 ng/L) compared with controls (mean: 165.2 ± 43.6 ng/L; P < 0.0005). IL-12 levels were enhanced by 25% in patients (18.3 ± 7.3 ng/L) compared with controls (14.7 ± 6.8 ng/L, P = 0.0576) although not reaching the statistical significance. IFN-γ and soluble CD14 levels were not increased. In vitro, LPS stimulated significantly and dose-dependently IL-18 secretion from PBMC. Incubation with ethanol reduced LPS-stimulated IL-18 secretion by about 50%. The mRNA expression of IL-18 in PBMC and the response of PBMC to ethanol and LPS was similar in CP patients and controls. In PBMC, no significant differences in IL-18 protein levels were detected between patients and controls. IL-18 protein levels were increased in CP tissues compared to normal pancreatic tissues. IL-18 was expressed by pancreatic acinar cells and by infiltrating inflammatory cells within the pancreas. CONCLUSION: IL-18 originates from the chronically inflammed pancreas and appears to be involved in the fibrotic destruction of the organ. PMID:17072982

    This study highlights the problem of levamisole-adulterated cocaine in context of active traffic participation. For the purposes of levamisole concentration monitoring in human serum, an analytical method based on LC-MS/MS and solid-phase extraction was applied. A Luna 5 μm C18 (2) 100 A, 150 mm × 2 mm column and a mobile phase consisting of A (H2 O/methanol = 95/5, v/v) and B (H2 O/methanol = 3/97, v/v), both with 10 mM ammonium acetate and with 0.1% acetic acid (pH = 3.2), were used. The validation experiments demonstrated that the method applied was appropriate for levamisole quantification in human serum. For 23% of levamisole-positive samples, the concentrations exceeded 20 ng/mL. Therefore, the interaction of this drug with cocaine has to be considered as important for active traffic participation. As a consequence, monitoring of levamisole concentration in human serum is recommended, as long as it is used as cocaine adulterant.

    Full Text Available Introduction : Atopic dermatitis (AD pathogenesis appears in the context of the correlation between cornified envelope proteins and immunological factors. Aim : To estimate the association between FLG R501X and 2282del4 gene mutations, –137 G/C IL-18 and –1112 C/T IL-13 gene polymorphisms and their influence on AD course and the risk in the Polish population. Material and methods : One hundred and fifty-two AD patients and 123 healthy volunteers were included into the study. Amplification refractory mutation system – polymerase chain reaction method was used. Results : 2282del4 FLG mutation, predominant (p = 0.04 in Polish AD patients, enhanced the risk of AD (OR = 2.35; p = 0.01 and was associated with itch (p = 0.023. GG genotype of IL-18 was prevailing in AD (p < 0.0001, associated with elevated IgE levels (p = 0.00074 and pruritus (p < 0.0001. GG genotype and G-allele in –137 position of IL-18 increased AD risk (OR = 5.4; p = 0.0001, respectively, OR = 5.3; p = 0.000029. –1112 C/T polymorphism of IL-13 was associated with elevated IgE levels (p = 0.00049, pruritus (p = 0.0005, SCORAD score (p = 0.02, concomitant asthma (p = 0.0087 and AD risk (OR = 2.02; p = 0.012. Coexistence of 2282del4 or R501X FLG gene mutation with GG genotype of IL-18 was associated with a 6-fold higher risk of AD (OR = 5.8; p = 0.00013, contrary to combined occurrence of FLG mutations with T-allele in –1112 position of IL-13 gene (OR = 0.12; p = 0.1. Conclusions : 2282del4 FLG mutation similarly to GG genotype and G-allele in –137 position of IL-18 gene enhance the risk of AD in the Polish population. Coexistence of FLG mutations with GG genotype of IL-18 may be helpful to estimate chances of AD development.

    Full Text Available Abstract Background There is a demand for serum markers for the routine assessment of the progression of liver cancer. We previously found that serum N-linked sugar chains are altered in hepatocellular carcinoma (HCC. Here, we studied glycomic alterations during development of HCC in a rat model. Results Rat HCC was induced by the hepatocarcinogen, diethylnitrosamine (DENA. N-glycans were profiled using the DSA-FACE technique developed in our laboratory. In comparison with control rats, DENA rats showed a gradual but significant increase in two glycans (R5a and R5b in serum total N-glycans during progression of liver cirrhosis and cancer, and a decrease in a biantennary glycan (P5. The log of the ratio of R5a to P1 (NGA2F and R5b to P1 [log(R5a/P1 and log(R5b/P1] were significantly (p Conclusions: We found an increase in core-α-1,6-fucosylated glycoproteins in serum and liver of rats with HCC, which demonstrates that fucosylation is altered during progression of HCC. Our GlycoTest model can be used to monitor progression of HCC and to follow up treatment of liver tumors in the DENA rat. This GlycoTest model is particularly important because a rapid non-invasive diagnostic procedure for tumour progression in this rat model would greatly facilitate the search for anticancer drugs.

    The overexpression of mutant p53 stimulates serum p53 antibody production in patients with colorectal carcinoma even in superficial tumors. Although the short-term perioperative monitoring of serum p53 antibody titers is reported to be useful in predicting tumor recurrence and patient survival in colorectal carcinoma, the clinical utility of the long-term monitoring of serum p53 antibody titers in patients with colorectal cancer remains unknown. Here, we report the 3-year monitoring of serum p53 antibody titers in a 60-year-old man with rectal cancer, clinical stage IV (T2N2M1b, lung and liver metastases), who was treated with chemotherapy and surgery. Screening tests for CEA (29.4 ng/ml), CA19-9 (41.1 U/ml), and serum p53 antibody (2170 U/ml) were positive before treatment. After chemotherapy with mFOLFOX6 + bevacizumab (B-mab), CEA and CA19-9 decreased to the normal range. However, serum p53 antibody titer remained positive (283 U/ml). After low anterior resection, the serum p53 antibody titer still remained positive (63.4 U/ml). Serum p53 antibody titer significantly changed and was associated with treatment response and tumor recurrence. In the last 6 months of the patient's life, serum p53 antibody titer gradually decreased, which possibly reflects the modification of the patient's immune response to p53 antigens.

  4. HBV X-gene: A new serum marker for anti-HBV therapy monitoring

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective: To address HBV serum nucleic acid markers for stages without apparent replication. Methods: DNA and RNA sequence segments from the X, C and pre C/C regions produced successively during replication were used as targets for quantitative PCR and RT/PCR. Results: The assays confirmed the preferential formation of intermediates blocked at early stages. They persisted as the only detectable type of serum HBV DNA even after one year of therapy. At reentry into viral replication due to emergence of drug resistant mutants, lamivudine resistance produced exclusively incomplete DNA minus strands, whereas the wild type virus immediately synthesized complete DNA minus strands. Conclusion:PCR assays used for monitoring complete suppression of HBV replication must target the X gene region.

    Full Text Available Background: Great concern about occupational exposure to chromium (Cr [VI] has been reported due to escalated risk of lung cancer in exposed workers. Consequences of occupational exposure to Cr (VI have been reported as oxidative stress and lung tissue damage. Objective: To investigate the feasibility of biological effect monitoring of chrome electroplaters through analysis of serum malondialdehyde (MDA. Methods: 90 workers directly involved in chrome electroplating—categorized into three equal groups based on their job as near bath workers, degreaser, and washers—and 30 workers without exposure to Cr (VI, served as the control group, were studied. Personal samples were collected and analyzed according to NIOSH method 7600. Serum MDA level was measured by HPLC using a UV detector. Results: Median Cr (VI exposure level was 0.38 mg/m3 in near bath workers, 0.20 mg/m3 in degreasers, and 0.05 mg/m3 in washers. The median serum MDA level of three exposed groups (2.76 μmol/L was significantly (p<0.001 higher than that in the control group (2.00 μmol/L. There was a positive correlation between electroplaters' level of exposure to Cr (VI and their serum MDA level (Spearman's ρ 0.806, p<0.001. Conclusion: Serum MDA level is a good biomarker for the level of occupational exposure to Cr (VI in electroplaters.

    Full Text Available BACKGROUND: A series of epidemiologic studies have identified the fungus Alternaria as a major risk factor for asthma. The airway epithelium plays a critical role in the pathogenesis of allergic asthma. These reports suggest that activated airway epithelial cells can produce cytokines such as IL-25, TSLP and IL-33 that induce Th2 phenotype. However the epithelium-derived products that mediate the pro-asthma effects of Alternaria are not well characterized. We hypothesized that exposure of the airway epithelium to Alternaria releasing cytokines that can induce Th2 differentiation. METHODOLOGY/PRINCIPAL FINDING: We used ELISA to measure human and mouse cytokines. Alternaria extract (ALT-E induced rapid release of IL-18, but not IL-4, IL-9, IL-13, IL-25, IL-33, or TSLP from cultured normal human bronchial epithelial cells; and in the BAL fluids of naïve mice after challenge with ALT-E. Both microscopic and FACS indicated that this release was associated with necrosis of epithelial cells. ALT-E induced much greater IL-18 release compared to 19 major outdoor allergens. Culture of naïve CD4 cells with rmIL-18 induced Th2 differentiation in the absence of IL-4 and STAT6, and this effect was abrogated by disrupting NF- κB p50 or with a NEMO binding peptide inhibitor. CONCLUSION/SIGNIFICANCE: Rapid and specific release of IL-18 from Alternaria-exposed damaged airway epithelial cells can directly initiate Th2 differentiation of naïve CD4(+ T-cells via a unique NF-κB dependent pathway.

    Interleukin-18 (IL-18) is a multi-functional and pleiotropic proinflammatory cytokine produced by various types of cells such as monocytes and macrophages.It acts as a critical link between innate and adaptive immune responses and is also an important modulator of cellular and humoral immunity.It takes part in immune responses by activating multiple signal transduction pathways,stimulating the production of interferon (IFN)-γ,and regulating the functions of immunocytes.IL-18 also promotes the differentiation of various T helper cell subsets as well as immune responses mediated by Th1 and Th2 lymphocytes.Studies have shown an abnormal expression of IL-18 in some inflammatory,autoimmune diseases and tumors,indicating a certain association of IL-18 with these entities.%白介素18是由单核细胞、巨噬细胞等多种细胞产生的一种具有多功能和多效应的前炎性因子,是固有和适应性免疫之间的一种重要联系,是细胞及体液免疫的调节物.通过激活多个信号转导途径、诱导干扰素γ的产生、调节免疫细胞功能参与机体免疫,其作用也体现在支持不同的Th细胞亚型的分化,促进Th1和Th2两型免疫应答.研究显示,白介素18在某些炎症、自身免疫性疾病和肿瘤中表达异常,提示白介素18与这些疾病的发生有一定的相关性.

    Full Text Available Abstract Background Systemic inflammation might cause neuronal damage and sustain neurodegenerative diseases and behavior impairment, with the participation of pro-inflammatory cytokines, like tumor necrosis factor (TNF-α and interleukin (IL-18. However, the potential contribution of these cytokines to behavioral impairment in the long-term period has not been fully investigated. Methods Wistar rats were treated with a single intraperitoneal injection of LPS (5 mg/kg or vehicle. After 7 days and 10 months, the animal behavior was evaluated by testing specific cognitive functions, as mnesic, discriminative, and attentional functions, as well as anxiety levels. Contextually, TNF-α and IL-18 protein levels were measured by ELISA in defined brain regions (that is, frontal cortex, hippocampus, striatum, cerebellum, and hypothalamus. Results Behavioral testing demonstrated a specific and persistent cognitive impairment characterized by marked deficits in reacting to environment modifications, possibly linked to reduced motivational or attentional deficits. Concomitantly, LPS induced a TNF-α increase in the hippocampus and frontal cortex (from 7 days onward and cerebellum (only at 10 months. Interestingly, LPS treatment enhanced IL-18 expression in these same areas only at 10 months after injection. Conclusions Overall, these results indicate that the chronic neuroinflammatory network elicited by systemic inflammation involves a persistent participation of TNF-α accompanied by a differently regulated contribution of IL-18. This leads to speculation that, though with still unclear mechanisms, both cytokines might take part in long-lasting modifications of brain functions, including behavioral alteration.

    Association of cytokine genes reflects their susceptibility towards infection and disease in household contacts (HHC) of pulmonary tuberculosis (PTB) patients. Hyperglycemia, a common factor in diabetics might influence their risk towards mycobacterium tuberculosis infection and disease development. This study determines the association of IL-6 and IL-18 cytokine gene variants of TB patients with diabetes mellitus (TBDM) and their HHC in Hyderabad. Single nucleotide polymorphisms of IL-6 (-174 G>C and -572 G>C) and IL-18 (-137 G>C and -607 C>A) cytokine genes were genotyped by Amplification Refractory Mutation System and Restriction Fragment Length polymerase chain reaction in total of 705 subjects comprising of TBDM, their HHC, PTB, DM and Healthy controls (HC). At IL-6 -174G>C variant, GG genotype, G allele in TBDM and TBDM HHC, at -572G>C variant, C allele in TBDM and GG haplotype in TBDM HHC were showing positive association, however DM have not shown any association at IL-6 polymorphic sites. With respect to the IL-18 gene polymorphisms, at -137 G>C variant, GG genotype was positively associated in PTB while at -607 C>A variant positive association was shown with AC genotype in TBDM, their HHC and DM; GACC diplotype in TBDM and GCGC in PTB. Our findings suggest that susceptible combination of IL-6 and IL-18 cytokine genes associated with disease in the HHCs highlight their risk of inclination towards the disease. Copyright © 2017.

    Full Text Available Polychlorinated biphenyls (PCBs are persistent organic chemicals that have been detected in human serum or tissues all over the world. These pollutants could exert a number of deleterious effects on humans and wildlife, including carcinogenic processes. The Spanish population of the Canary Islands was evaluated with respect to PCB levels more than ten years ago showing lower levels than other Western populations. The objective of our study was to assess the current level of contamination by PCBs showed by this population. We measured serum PCBs in a sample of healthy adult subjects (206 serum samples from subjects with an average age of 66 years old to evaluate the potential modification of PCB serum levels in this population during the last decade. PCB congeners (28, 52, 77, 81, 101, 105, 114, 118, 123, 126, 138, 153, 156, 157, 167, 169, 180, and 189 were measured by gas chromatography-mass spectrometry (GC/MS. Our results showed that PCB residues were found in 84% of serum samples analyzed, the congeners 28, 153 and 180 being the most frequently detected and at the highest median values (0.1 ng/mL. In addition, the median concentration of the sum of those PCBs considered as markers of environmental contamination by these chemicals (Marker-PCBs was 0.6 ng/mL, reaching values as high as as 2.6 ng/mL in the 95th percentile. Levels of the sum of PCBs with toxic effects similar to dioxins (dioxin-like PCBs reached median values of 0.4 ng/mL in the 95th percentile. The reported levels are similar to those described previously in this population more than ten years ago, in the sense that the inhabitants of the Canary Archipelago show levels of PCB contamination lower than the majority of populations from developed countries. These findings suggest that currently there is not any active source of these chemicals in this archipelago. Nevertheless, as foods seem to be a relevant source for these compounds, Public Health authorities should monitor the

    We had examined the immunogenicity of a series of plasmid DNAs which include neuraminidase (NA) and nucleoprotein (NP) genes from avian influenza virus (AIV). The interleukin-15 (IL-15) and interleukin-18 (IL-18) as genetic adjuvants were used for immunization in combination with the N1 and NP AIV genes. In the first trial, 8 groups of chickens were established with 10 specific-pathogen-free (SPF) chickens per group while, in the second trial 7 SPF chickens per group were used. The overall N1 enzyme-linked immunosorbent assay (ELISA) titer in chickens immunized with the pDis/N1+pDis/IL-15 was higher compared to the chickens immunized with the pDis/N1 and this suggesting that chicken IL-15 could play a role in enhancing the humoral immune response. Besides that, the chickens that were immunized at 14-day-old (Trial 2) showed a higher N1 antibody titer compared to the chickens that were immunized at 1-day-old (Trial 1). Despite the delayed in NP antibody responses, the chickens co-administrated with IL-15 were able to induce earlier and higher antibody response compared to the pDis/NP and pDis/NP+pDis/IL-18 inoculated groups. The pDis/N1+pDis/IL-15 inoculated chickens also induced higher CD8+ T cells increase than the pDis/N1 group in both trials (P0.05) in inducing CD4+ and CD8+ T cells when co-administered with the pDis/IL-18 in both trials in comparison to the pDis/NP. Our data suggest that the pDis/N1+pDis/IL-15 combination has the potential to be used as a DNA vaccine against AIV in chickens.

    Rabies virus is a highly neurovirulent RNA virus, which causes about 59000 deaths in humans each year. Previously, we described macrophage cytotoxicity upon infection with rabies virus. Here we examined the type of cell death and the role of specific caspases in cell death and disease development upon infection with two laboratory strains of rabies virus: Challenge Virus Standard strain-11 (CVS-11) is highly neurotropic and lethal for mice, while the attenuated Evelyn–Rotnycki–Abelseth (ERA) strain has a broader cell tropism, is non-lethal and has been used as an oral vaccine for animals. Infection of Mf4/4 macrophages with both strains led to caspase-1 activation and IL-1β and IL-18 production, as well as activation of caspases-3, -7, -8, and -9. Moreover, absence of caspase-3, but not of caspase-1 and -11 or -7, partially inhibited virus-induced cell death of bone marrow-derived macrophages. Intranasal inoculation with CVS-11 of mice deficient for either caspase-1 and -11 or -7 or both IL-1β and IL-18 led to general brain infection and lethal disease similar to wild-type mice. Deficiency of caspase-3, on the other hand, significantly delayed the onset of disease, but did not prevent final lethal outcome. Interestingly, deficiency of caspase-1/11, the key executioner of pyroptosis, aggravated disease severity caused by ERA virus, whereas wild-type mice or mice deficient for either caspase-3, -7, or both IL-1β and IL-18 presented the typical mild symptoms associated with ERA virus. In conclusion, rabies virus infection of macrophages induces caspase-1- and caspase-3-dependent cell death. In vivo caspase-1/11 and caspase-3 differently affect disease development in response to infection with the attenuated ERA strain or the virulent CVS-11 strain, respectively. Inflammatory caspases seem to control attenuated rabies virus infection, while caspase-3 aggravates virulent rabies virus infection. PMID:28280602

    The pathogenesis of viral bronchiolitis is poorly understood. The aim of this study was to analyze interleukin (IL)-15, IL-18 and interferon (IFN)-γ concentrations and the activity of NK cells and CD4(+) and CD8(+) lymphocytes in 23 children not older than 30 months of age with acute viral bronchiolitis using blood samples drawn within the first 24 h of their hospital admission, in comparison to a healthy group. In children with bronchiolitis, the mean concentrations of IL-15, IL-18 and IFN-γ were 9.39±11.55, 884.03±645.44 and 17.92±27.14 pg/ml, respectively, and were significantly higher than those in the control group [2.34±0.61 pg/ml (p<0.05), 248.69±98.73 pg/ml (p<0.001) and 2.75±1.72 pg/ml (p<0.005), respectively]. In the bronchiolitis group, mean z-scores were -1.15±1.9 for CD4(+) cells and -0.9±1.23 for CD8(+) cells; these scores were significantly lower than those of the general Polish population (p<0.001 and <0.01, respectively). However, the mean z-score of the ratio of CD4(+)/CD8(+) and the NK cell count in children with bronchiolitis did not differ significantly from those of the controls. In conclusion, cytokines such as IL-15, IL-18 and IFN-γ play a role in the pathogenesis of bronchiolitis in children.

    Full Text Available Introduction & Objective: Leishmaniasis is a major worldwide health problem throughout the world and in Iran as well. Skin lesions are mostly healing but nonhealing cases have also increased recently. T-helper type1 (Th1 responses induction helps the patients to resist against the disease while T-helper type2 (Th2 responses cause susceptibility to disease. With the assessment of IL-5, IL-10, IL-12, and IL-18 cytokines secreted from peripheral blood mononuclear cells (PBMC in leishmaniasis healing and nonhealing patients, their role in curing leishmaniasis was surveyed.Materials & Methods: Cytokines secreted from PBMCs of 60 healing and nonhealing patients and also control group referred to Ab-o-Bargh number1 clinic and Mashhad Qaem hospital during 2007 were evaluated Elisa commercial kits after stimulation by leishmania antigen and mitogen in vitro. Results: Healing patients PBMCs secreted IL-12 (236.55±38.00 pg/ml more than non healing patients (p<0.05 while in nonhealing patients IL-5 (52.14±65.21 pg/ml and IL-10 (30.19±18.73 pg/ml secreted more than healing patients (p<0.005. Also IL-18 secreted significantly higher in nonhealing patients compared with healing patients (p=0.003.Conclusion: According to the results It can be concluded that IL-12 is secreted more in healing patients than nonhealing patients but IL-18, which causes the increase of IL-12 secretion and the activation of Th1 cells during IL-12 secretion decrease, secrets more in nonhealing patients, induces Th2 responses and results in disease progression.

    Full Text Available Microglia are activated during pathological events in the brain and are capable of releasing various types of inflammatory cytokines. Here we demonstrate that the addition of 5% microglia activated by 1 µg/ml lipopolysaccharides (LPS to hippocampal cultures up-regulates Na+ current densities (INavD of bipolar as well as pyramid-shaped neurons, thereby increasing their excitability. Deactivation of microglia by the addition of 10 ng/ml transforming growth factor-β (TGF-β decreases INavD below control levels suggesting that the residual activated microglial cells influence neuronal excitability in control cultures. Preincubation of hippocampal cultures with 10 ng/ml tumor necrosis factor-α (TNF-α, a major cytokine released by activated microglia, up-regulated INavD significantly by ~30% in bipolar cells, whereas in pyramid-shaped cells the up-regulation only reached an increase of ~14%. Incubation of the cultures with antibodies against either TNF-receptor 1 or 2 blocked the up-regulation of INavD in bipolar cells, whereas in pyramid-shaped cells increases in INavD were exclusively blocked by antibodies against TNF-receptor 2, suggesting that both cell types respond differently to TNF-α exposure. Since additional cytokines, such as interleukin-18 (IL-18, are released from activated microglia we tested potential effects of IL-18 on INavD in both cell types. Exposure to 5-10 ng/ml IL-18 for 4 days increased INavD in both pyramid-shaped as well as bipolar neurons, albeit the dose-response curves were shifted to lower concentrations in bipolar cells.

    Microglia are activated during pathological events in the brain and are capable of releasing various types of inflammatory cytokines. Here, we demonstrate that the addition of 5% microglia activated by 1 μg/ml lipopolysaccharides (LPS) to hippocampal cultures upregulates Na(+) current densities (INavD) of bipolar as well as pyramid-shaped neurons, thereby increasing their excitability. Deactivation of microglia by the addition of 10 ng/ml transforming growth factor-β (TGF-β) decreases INavD below control levels suggesting that the residual activated microglial cells influence neuronal excitability in control cultures. Preincubation of hippocampal cultures with 10 ng/ml tumor necrosis factor-α (TNF-α), a major cytokine released by activated microglia, upregulated INavD significantly by ~30% in bipolar cells, whereas in pyramid-shaped cells, the upregulation only reached an increase of ~14%. Incubation of the cultures with antibodies against either TNF-receptor 1 or 2 blocked the upregulation of INavD in bipolar cells, whereas in pyramid-shaped cells, increases in INavD were exclusively blocked by antibodies against TNF-receptor 2, suggesting that both cell types respond differently to TNF-α exposure. Since additional cytokines, such as interleukin-18 (IL-18), are released from activated microglia, we tested potential effects of IL-18 on INavD in both cell types. Exposure to 5-10 ng/ml IL-18 for 4 days increased INavD in both pyramid-shaped as well as bipolar neurons, albeit the dose-response curves were shifted to lower concentrations in bipolar cells. Our results suggest that by secretion of cytokines, microglial cells upregulate Na(+) current densities in bipolar and pyramid-shaped neurons to some extent differentially. Depending on the exact cytokine composition and concentration released, this could change the balance between the activity of inhibitory bipolar and excitatory pyramid-shaped cells. Since bipolar cells show a larger upregulation of

    Objective:To study the relationship of serum insulin-like growth factor-related indicators and interleukins with pregnancy-induced hypertension.Methods:34 patients with gestational hypertension, 27 patients with mild preeclampsia, 18 patients with severe preeclampsia and 50 healthy women were selected as the research subjects, serum was collected to determine serum IGF-I, IGF-II, IGFBP-1, IL-6, IL-8 and IL-18 content, and the placenta was collect to determine IGF-I, IGF-II, IGFBP-1, IL-6, IL-8 and IL-18 content.Results: IGF-I and IGF-II levels in placenta tissue and serum of gestational hypertension group, mild preeclampsia group and severe preeclampsia group were significantly lower than those of control group, and IGFBP-1, IL-6, IL-8 and IL-18 levels were significantly higher than those of control group; serum IGF-I and IGF-II levels were negatively correlated with IL-6, IL-8 and IL-18 levels, and serum IGFBP-1 level was positively correlated with IL-6, IL-8 and IL-18 levels.Conclusion:decreased serum IGF-I, IGF-II levels and increased serum IGFBP-1, IL-6, IL-8 and IL-18 levels are associated with pregnancy-induced hypertension, and decreased IGF-I and IGF-II levels and increased IGFBP-1 level are closely related to increased levels of interleukins.

  6. Dystromirs as serum biomarkers for monitoring the disease severity in Duchenne muscular Dystrophy.

    Directory of Open Access Journals (Sweden)

    Irina T Zaharieva

    Full Text Available Duchenne muscular Dystrophy (DMD is an inherited disease caused by mutations in the dystrophin gene that disrupt the open reading frame, while in frame mutations result in Becker muscular dystrophy (BMD. Ullrich congenital muscular dystrophy (UCMD is due to mutations affecting collagen VI genes. Specific muscle miRNAs (dystromirs are potential non-invasive biomarkers for monitoring the outcome of therapeutic interventions and disease progression. We quantified miR-1, miR-133a,b, miR-206 and miR-31 in serum from patients with DMD, BMD, UCMD and healthy controls. MiR-1, miR-133a,b and miR-206 were upregulated in DMD, but unchanged in UCMD compared to controls. Milder DMD patients had higher levels of dystromirs than more severely affected patients. Patients with low forced vital capacity (FVC values, indicating respiratory muscle weakness, had low levels of serum miR-1 and miR-133b. There was no significant difference in the level of the dystromirs in BMD compared to controls. We also assessed the effect of dystrophin restoration on the expression of the five dystromirs in serum of DMD patients treated systemically for 12 weeks with antisense oligomer eteplirsen that induces skipping of exon 51 in the dystrophin gene. The dystromirs were also analysed in muscle biopsies of DMD patients included in a single dose intramuscular eteplirsen clinical trial. Our analysis detected a trend towards normalization of these miRNA between the pre- and post-treatment samples of the systemic trial, which however failed to reach statistical significance. This could possibly be due to the small number of patients and the short duration of these clinical trials. Although longer term studies are needed to clarify the relationship between dystrophin restoration following therapeutic intervention and the level of circulating miRNAs, our results indicate that miR-1 and miR-133 can be considered as exploratory biomarkers for monitoring the progression of muscle weakness

    Full Text Available BACKGROUND: Serum baseline tryptase (sBT is a minor diagnostic criterion for systemic mastocytosis (SM of undetermined prognostic impact. We monitored sBT levels in indolent SM (ISM patients and investigated its utility for predicting disease behaviour and outcome. METHODS: In total 74 adult ISM patients who were followed for ≥48 months and received no cytoreductive therapy were retrospectively studied. Patients were classified according to the pattern of evolution of sBT observed. RESULTS: Overall 16/74 (22% cases had decreasing sBT levels, 48 (65% patients showed increasing sBT levels and 10 (13% patients showed a fluctuating pattern. Patients with significantly increasing sBT (sBT slope ≥0.15 after 48 months of follow-up showed a slightly greater rate of development of diffuse bone sclerosis (13% vs. 2% and hepatomegaly plus splenomegaly (16% vs. 5%, as well as a significantly greater frequency of multilineage vs. mast cells (MC-restricted KIT mutation (p = 0.01 together with a greater frequency of cases with progression of ISM to smouldering and aggressive SM (p = 0.03, and a shorter progression-free survival (p = 0.03. CONCLUSIONS: Monitoring of sBT in ISM patients is closely associated with poor prognosis disease features as well as with disease progression, pointing out the need for a closer follow-up in ISM patients with progressively increasing sBT values.

    BACKGROUND: Diabetic nephropathy (DN) is known as an acute microvascular complexity as a subsequence progression in diabetes mellitus type 1 and 2. Many evidence pointed that the proinflammatory cytokine Interleukin (IL)-18 might be involved in the pathogenesis of DN. AIM: The current study aimed to evaluate the association of serum IL-18 and its promoter gene polymorphisms with diabetic nephropathy. METHODS: This study included 62 diabetic nephropathy patients (DN group) compared to 52 diabetes mellitus patients (DM group). The two groups were subjected to anthropometry assessment, molecular studies including SNP genotyping by RFLP and finally statistical analysis. RESULTS: The assessment of the serum IL-18 level and the frequencies of its allele and haplotype: -137G/C, -607C/A and -656G/T among the DN and DM subjects revealed that -137G allele has significant variation between DN and DM subjects (about 80.8%, P = 0.05) but, no significant variation in -607 or -656 alleles IL-18 gene promoter. CONCLUSION: These data confirm the impact of high serum IL-18 and the haplotype of the polymorphism located in the promoter region of the IL-18 gene with the DN. PMID:27703550

    . The two tiered approach may offer an unique opportunity to provide an alternative method to the Local Lymph Node Assay (LLNA). These assays are both based on the use of human keratinocytes, which have been shown over the last two decades, to play a key role in all phases of skin sensitization.......At present, the identification of potentially sensitizing chemicals is carried out using animal models. However, it is very important from ethical, safety and economic point of view to have biological markers to discriminate allergy and irritation events, and to be able to classify sensitizers...... sensitizers from non-sensitizers. This study describes two of these assays, which when used in a tiered strategy, may be able to identify contact sensitizers and also to quantify sensitizer potency.

    Dysregulated microglial responses are central in neurodegenerative proteinopathies, including amyotrophic lateral sclerosis (ALS) and frontotemporal lobar disease (FTLD). Pathologic TDP-43, which is typically found in intracellular inclusions, is a misfolding protein with emerging roles in ALS and FTLD. Recently, TDP-43 species have been found in extracellular fluids of patients; however, the overall implications of TDP-43-mediated signaling linked to neuroinflammation are poorly understood. Our work-the first, to our knowledge, to focus on innate immunity responses to TDP-43 aggregates-shows that such species are internalized by microglia and cause abnormal mobilization of endogenous TDP-43. Exposure to TDP-43 aggregates elicited not only IL-1β, but also NLRP3-dependent and noncanonical IL-18 processing. Moreover, we report a link between TDP-43 and neuronal loss via the apoptosis-independent emerging roles of caspase-3 in neurotoxic inflammation. Our results further support the view of noncell autonomous neurodegenerative mechanisms in ALS. Remarkably, we demonstrate that TDP-43 aggregates bind to and colocalize with MAPK/MAK/MRK overlapping kinase (MOK) and show that its phosphorylation status is disrupted. Finally, we show that this TDP-43-caused activation state can be altered by exogenous Hsp27 and Hsp70 chaperones. Our study provides new insight into the immune phenotype, mechanisms, and signaling pathways that operate in microglial neurotoxic activation in ALS.-Leal-Lasarte, M. M., Franco, J.

    Abstract Background: Identifying translatable, non-invasive biomarkers of muscular dystrophy that better reflect the disease pathology than those currently available would aid the development of new therapies, the monitoring of disease progression and the response to therapy. Objective: The goal of this study was to evaluate a panel of serum protein biomarkers with the potential to specifically detect skeletal muscle injury. Method: Serum concentrations of skeletal troponin I (sTnI), myosin light chain 3 (Myl3), fatty acid binding protein 3 (FABP3) and muscle-type creatine kinase (CKM) proteins were measured in 74 Duchenne muscular dystrophy (DMD), 38 Becker muscular dystrophy (BMD) and 49 Limb-girdle muscular dystrophy type 2B (LGMD2B) patients and 32 healthy controls. Results: All four proteins were significantly elevated in the serum of these three muscular dystrophy patient populations when compared to healthy controls, but, interestingly, displayed different profiles depending on the type of muscular dystrophy. Additionally, the effects of patient age, ambulatory status, cardiac function and treatment status on the serum concentrations of the proteins were investigated. Statistical analysis revealed correlations between the serum concentrations and certain clinical endpoints including forced vital capacity in DMD patients and the time to walk ten meters in LGMD2B patients. Serum concentrations of these proteins were also elevated in two preclinical models of muscular dystrophy, the mdx mouse and the golden-retriever muscular dystrophy dog. Conclusions: These proteins, therefore, are potential muscular dystrophy biomarkers for monitoring disease progression and therapeutic response in both preclinical and clinical studies.

    Body condition in wild ungulates is traditionally evaluated during the necropsy of animals on the basis of the weight of fat stored around or within the vital organs, the weight of the organs themselves, and their derived indices. However, sometimes it is important to evaluate the nutritional status of the animal by means of blood and serum analyses and the interpretation of specific parameters. Only in a very few studies is the nutritional status of the animal obtained by blood biochemistry and, when obtained, compared with the values for body condition obtained by anatomic dissection. In this study, the usefulness of two serum parameters, total serum proteins (TSP) and serum triglycerides (ST), was assessed in the monitoring of the body condition of Iberian wild goats (Capra pyrenaica). In addition, their relationship with the kidney fat index (KFI) and its components, kidney mass without fat (KM) and kidney fat (KF) is evaluated. A total of 25 wild goats from the Sierra Nevada National Park (southern Iberian Peninsula) that were shot by hunters were used in this study. The parameter TSP was found to be correlated with KM, and ST was correlated with both KM and KFI. Hence, both TSP and ST can be used for monitoring physical condition in wild and captive Iberian wild goats.

    2015-02-01

    Conclusions: The study findings revealed that in both groups of obese and lean men, serum levels of IL-18 positively correlated with insulin resistance and triglyceride, and negatively correlated with high-density lipoprotein. Furthermore, within obese individuals that have elevated IL-18 levels, this can be associated with disorder in glycemic control and lipid profile, and thus, with increased risk of cardiovascular and metabolic disorders. IL-18 levels do not appear to have any correlations with acylated ghrelin, growth hormone, total cholesterol, and low-density lipoprotein.

    Full Text Available Gestational Diabetes mellitus is the condition of glucose intolerance that begins during pregnancy which is associated with both fetal and maternal complications. The measurement of serum fructosamine and glycated hemoglobin in normal and diabetic pregnancy used to investigate the influence of maternal and gestational age on concentrations of glycated proteins in serum and used to evaluate the patient′s treatment. This study was done to measure the level of serum fructosamine and Glycated hemoglobin (HbA1c in Gestational Diabetes mellitus (GDM patients and to compare with pregnant women without diabetes and healthy non-pregnant adults, to determine the pattern of change in serum fructosamine, influence of serum fructosamine and HbA1c values and to evaluate the efficacy of patient′s treatment. In this study the level of fructosamine was positively correlated to HbA1c during 2 nd trimesters of gestational period, implying that the level of fructosamine can be used to screen Gestational diabetes mellitus. Correlation of glycated hemoglobin values with serum fructosamine measurements in the accurate determination of glycaemic control provides confirmation of the utility of fructosamine measurement.

    2014-10-01

    Full Text Available The paper delivers a critical review of the research data on the crack initiation and crack growth patterns characteristic of the components of the spline-bolted joints between the propeller shaft and reducer shaft at An-24, An-26, and Il-18 aircrafts. Cracks in the shafts nucleated because of reduced bolt-fastening force. Actually, the bolt (bolts failed first (also by fatigue and then fatigue cracks nucleated and grew in the shafts, the spline surface fretting zones and/or sharp edges of the attachment (bolt-conducting holes making the crack origin sites. The crack growth history shows itself through the regular Macro-Beach Marks, each mark sequentially pointing to the next loading event of the propeller shaft, i.e., to each next flight. The cracks cease growing for some while in the airscrews and their shafts just replaced to another aircraft. For the airscrew shafts, the critically assessed data show the crack growth period Np ranging as five to ten percent of a total running period Nf . We recommend performing nondestructive inspection of the airscrew shafts on every 250- hour running period to ensure the safety flights.

    CD4(+) T lymphocytes are required to induce spontaneous autoimmune diabetes in the NOD mouse. Since pancreatic β cells upregulate Fas expression upon exposure to pro-inflammatory cytokines, we studied whether the diabetogenic action of CD4(+) T lymphocytes depends on Fas expression on target cells. We assayed the diabetogenic capacity of NOD spleen CD4(+) T lymphocytes when adoptively transferred into a NOD mouse model combining: (i) Fas-deficiency, (ii) FasL-deficiency, and (iii) SCID mutation. We found that CD4(+) T lymphocytes require Fas expression in the recipients' target cells to induce diabetes. IL-1β has been described as a key cytokine involved in Fas upregulation on mouse β cells. We addressed whether CD4(+) T cells require IL-1β to induce diabetes. We also studied spontaneous diabetes onset in NOD/IL-1 converting enzyme-deficient mice, in NOD/IL-1β-deficient mice, and CD4(+) T-cell adoptively transferred diabetes into NOD/SCID IL-1β-deficient mice. Neither IL-1β nor IL-18 are required for either spontaneous or CD4(+) T-cell adoptively transferred diabetes. We conclude that CD4(+) T-cell-mediated β-cell damage in autoimmune diabetes depends on Fas expression, but not on IL-1β unveiling the existing redundancy regarding the cytokines involved in Fas upregulation on NOD β cells in vivo.

    2017-09-05

    High-end analytical methods provide excellent data but may lack the robustness required in large analytical studies. In particular complex chemical matrices may cause difficulties and increase the need for extensive sample preparation. For screening of patients we thus developed a low-tech assay to monitor bradykinin degradation by serum proteases. The bradykinin concentration mirrors the activity of angiotensin-converting enzyme (ACE). Dabsylated bradykinin (DBK) and its labeled fragments DBK1-8 and DBK1-5 were visualized by thin-layer chromatography using only 3μL of serum. Lower DBK1-5 levels indicated reduced ACE activity due to medication (ACE-inhibitors) or disease. Provided that purified DBK is available, the assay protocol itself is very simple and does not require any expensive high-end equipment. Copyright © 2017 Elsevier B.V. All rights reserved.

    In this paper, a metamaterial (MM) resonator used as a sensitive biosensor is designed and fabricated for monitoring the interaction between bovine serum albumin (BSA) solution and four kinds of drug solutions in real time. The transmission spectra of the resonator are simulated and measured with terahertz time-domain spectroscopy system where the distinct resonance frequency shifts are observed. The experimental results indicate that the interactions between BSA and every kind of solution are violent before the reaction reaches equilibrium, and the reaction solutions manifest varying permittivity. Moreover, different reaction solutions show different frequency shifts and reaction times. The MM resonator worked as an effective biosensor achieves to monitor the interaction between BSA and drug solutions in real time, which is very useful for the development of novel drugs and other biomedical applications.

    Reagents that allows detection and monitoring of crucial biomarkers with luminescence ON response have significance in clinical diagnostics. A new coumarin derivative is reported here, which could be used for specific and efficient chemodosimetric detection of cysteine, an important biomarker. The probe is successfully used for studying the biochemical transformation of N-acetylcysteine, a commonly prescribed Cys supplement drug to Cys by aminoacylase-1 (ACY-1), an important and endogenous mammalian enzyme. The possibility of using this reagent for quantification of ACY-1 in blood serum samples is also explored. Nontoxic nature and cell membrane permeability are key features of this probe and are ideally suited for imaging intracellular Cys in normal and cancerous cell lines. Our studies have also revealed that this reagent could be utilized as a redox switch to monitor the hydrogen-peroxide-induced oxidative stress in living SW480 cell lines. Peroxide-mediated cysteine oxidation has a special significance for understanding the cellular-signaling events.

    The automated quantification of serum free kappa and lambda light chain concentrations provides a highly sensitive tool for the diagnosis and monitoring of monoclonal gammopathies. An abnormal kappa:lambda ratio supports the presence of clonal plasma cell expansion and requires further investigation. More than 94% of myeloma, light chain myeloma, and AL amyloidosis and, likewise, a majority of patients with light chain deposition disease are detectable with this technology. Importantly, these assays identify M-proteins in most patients with oligosecretory disease and permit their recruitment into clinical trials from which they have been previously excluded. Combining serum free light chain testing with traditional electrophoresis provides > 99% accuracy in the first-line diagnosis of monoclonal gammopathies and eliminates the need for urine testing in most instances. One third of patients with monoclonal gammopathy of undetermined significance have an abnormal free light chain ratio, and these patients harbor a greater risk of progression to plasma cell dyscrasia. For monitoring response to therapy, the international uniform response criteria define a normal free light chain ratio as an essential element of the "stringent complete response" category. Because the half-life of free light chains is chain measurements at short sampling intervals allow real-time measurement of treatment-induced tumor kill, and provide prompt indications of chemosensitivity, dose adequacy, need for alternative approaches, and even prognosis, as demonstrated in AL amyloidosis if the involved free light chain concentration normalizes. Clinical applications of these assays will likely increase as their utility is more widely explored.

    This article reports on the development of a simple and cost-effective bioassay for the detection of biotin in urine and serum, based on the very selective binding of avidin and biotin. Avidin was allowed to react without isolating it from egg white. Egg white was treated with the dye HABA, which binds to avidin. Upon subsequent treatment with biotin, HABA is released due to the high affinity of biotin to avidin. The amount of HABA released is proportional to the amount of biotin used.

    Objective The present study aims to analyze the levels of resistin, tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, IL-18, and C-reactive protein (CRP) in patients with Alzheimer’s disease (AD) and also investigate a potential relationship between resistin levels and TNF-α, IL-1β, IL-6, IL-18, and CRP levels in patients with AD. Methods The study included fifty patients with AD and 30 healthy controls with normal cognitive functions. The serum resistin, TNF-α, IL-1β, IL-6, IL-18, and CRP levels were assessed. We performed a Mini-Mental State Examination (MMSE) to evaluate the general cognitive performance. Results The mean serum resistin, IL-1β, IL-18, and TNF-α levels were significantly higher in patients with AD compared with the controls (p=0.026, p=0.002, p=0.003, and p=0.038, respectively). The IL-6 and CRP levels did not differ between the groups (p=0.874 and p=0.941). The resistin levels were positively correlated with the levels of CRP and IL-18 (r=0.526, p0.05 for all). Conclusion Serum resistin levels were significantly increased and correlated with some inflammatory markers in AD patients, suggesting that resistin might play a role in the inflammatory process of AD.

    Full Text Available Background/Aim. Unknown primary tumors represent a heterogeneous group of malignancies that are indicative of ominous prognosis. Cancer of unknown primary site (CUP is defined as the lack of any detectable primary site after full evaluation, and accounts for approximately 3-5% of all newly diagnosed patients with malignancies. The aim of this report was to present the prognostic and predictive value of 8 serum tumor markers in this group of patients. Methods. The study involved 63 patients. On histological examination, all the patients were presented with metastatic tumors whose primary site (origin could not be detected with noninvasive diagnostic techniques. Following the routine light microscopy, all histological findings were classified into one of the following three groups: plano-cellular carcinoma - 8 patients; adenocarcinoma - 33 patients; unclassifiable (undifferentiated carcinoma - 22 patients. In all the cases we evaluated 8 serum tumor markers: alpha-fetoproteins (AFP, chronic gonadotrophin beta submit, human (beta-HCG, neuron specific enolase (NSE, marker of malignant ovarian tumors (CA 125, prostate-specific antigene (PSA, marker of malignant brest tumor (CA 15-3, marker of malignant pancreas tumor and gastrointestinal tumor (Ca 19-9, carcinoembryonic antigen (CEA at the time of diagnosis. The patients on chemotherapy had the markers determined after the third and sixth chemocycle, i.e. at the time of illness progression observation, if present. The patients responding to chemotherapy with complete response (CR, partial response (PR or stable disease (SD had the markers determined after three-month periods until the time of relapse or progression. Chemotherapy was applied in 32 patients (20 females and 12 males, aged 29-70 years, who met the inclusion criteria. The following chemotherapy regimen was used: doxorubicin 50mg/m2 (day 1, cisplatin 60mg/m2 (day 1, and etoposide 120 mg/m2 (days 1-3. The period between two chemotherapy

    2013-12-01

    Patients with advanced diseases are exposed to many causes of hypomagnesaemia, the most frequent being pharmacological causes through the administration of chemotherapy, antibiotics, proton pump inhibitors, and so on. The objective of this review is to demonstrate the importance of measuring magnesium levels in the blood of these patients. In the last decade, studies have been published showing a direct relationship between low levels of magnesium and nonspecific symptoms including pain that is difficult to control. Nevertheless, hypomagnesaemia is still being omitted as a differential diagnosis in many such patients. A review of recently published studies regarding the clinical presentation of hypomagnesaemia in patients with advanced cancer and other chronic diseases is presented. Many of the clinical conditions are reportedly alleviated with intravenous or even oral magnesium administration. The presence of nonspecific neurological signs and risk factors for hypomagnesaemia could serve as an indication that serum magnesium should be determined in these patients.

    AIM: To Study the interaction of macrophage colony-stimulating factor (M-CSF) and interleukin-10 (IL-10) in productions of IL-12 and IL-18 and expressions of CD14, CD23, and CD64 by human monocytes. METHODS:Purified adherent human monocytes were cultured with M-CSF or IL-10 alone, or with M-CSF+IL-10 and 2-3d later, the culture supernatants and cells were separated and collected. IL-12P40 and IL-18 levels in the supernatants were determined by ELISA and the percentages of CD14, CD23, and CD64 positive cells were examined by flow cytometry. RESULTS: (1) IL-10 decreased M-CSF-induced IL-18 levels, while M-CSF further reduced IL-12P40 level in the culture supernatants of IL-10-treated monocytes; (2) IL-10 alone had no effect on the percentage of CD14-positive cells, but further increased the percentage of CD14-positive cells induced by M-CSF; M-CSF alone had no effect on the percentage of CD64-positive cells, but further increased the percentage of CD64-positive cells induced by IL-10; (3) IL-10 decreased the percentage of CD23-positive cells induced by M-CSF.CONCLUSION: Between M-CSF and IL-10, there were antagonistic effects on inducing IL-18 and CD23 expressions by monocytes; there were also synergistic effects on inhibiting IL-12P40 production and inducing CD 14 and CD64 expressions by monocytes.

    The cathodic reduction at the mercury electrode of a biliverdin IX alpha-serum albumin complex at physiological pH in an aqueous buffer containing percentages of DMSO ranging from 4% to 20% is studied by cyclic voltametry and controlled potential coulometry. The progression of pigment disappearance and the (stereochemical) nature of the product are monitored by chromatography, UV-visible absorption and circular dichroism spectroscopy. Upon reduction, albumin-bound biliverdin IX alpha, with a slight preference for the P-helicity, affords the corresponding bound bilirubin IX alpha -with an M-chirality conformation. The complex is reduced at -0.64 V (vs. SCE; 8% DMSO), only a little shifted compared to reduction of free biliverdin IX alpha under the same conditions. In contrast, an analogous bilirubin IX alpha-serum albumin complex is essentially inert towards cathodic reduction under conditions where free bilirubin IX alpha is reduced, indicating a better shielding by the protein of the bilirubin IX alpha molecule from the electrode surface. The presence of relative position (as in the biliverdins IX alpha and XIII alpha) or absence (as in mesobiliverdin IX alpha) of vinyl groups in the pigment does not have a significant effect upon its electroreduction behaviour, indicating that the process is not sensitive to the subtle differences imposed by vinyl groups upon the structure of the corresponding biliverdin-albumin complexes.

    An efficient, selective and cost-effective liquid chromatographic assay was developed and validated for the simultaneous quantification of ciprofloxacin and rosuvastatin in Active Pharmaceutical Ingredients (API), pharmaceutical formulations and in human serum. The chromatographic system consisted of mobile phase methanol-water, 90:10 v/v at pH 3.0 adjusted with o-phosphoric acid, pumped at 1.0 mL/min through a prepacked Purospher Star C18 (5 µm, 25 × 0.46 cm) column and effluent was monitored at the isosbestic point (255 nm) as well as at the λmax of individual drugs (243 and 271 nm). The method was validated over a linear concentration range of 0.25-15 µg/mL for ciprofloxacin and 0.33-20 µg/mL for rosuvastatin (r(2)  ≥ 0.999). The ranges of reliable response (limits of detection and quantitation) for ciprofloxacin were 3-15 and 9-45 ng/mL and 17-29 and 52-88 ng/mL, respectively, for rosuvastatin in all API, pharmaceutical formulations and human serum. Analytical recovery from human serum was >98% and relative standard deviation (RSD) was ciprofloxacin and rosuvastatin, respectively. No matrix interferences, ion suppression/enhancement and carry-over were detected. The total assay run time was less than 5 min. In another study, for optimum performance the detector was programmed for multiwavelength scanning at the absorption maxima of each component. Consequently, the linearity range was improved and limit of detection and quantitation values were down to 1-4 and 4-12 ng/mL for ciprofloxacin and 3-5 and 9-15 ng/mL for rosuvastatin, respectively. The validation parameters fitted ICH guidelines through the isosbestic and individual λmax approach. The small sample volume and simplicity of preparation make this method suitable for use in human serum samples, pharmaceutical formulations, quality control, drug-drug interaction studies, clinical laboratories, drug research centers and forensic medical centers.

    2016-01-01

    BACKGROUND: Circulating hypermethylated RASSF1A could be a novel and potential useful marker for monitoring patients with metastatic breast cancer. Technical obstacles include fragmentation of the circulating DNA, fluctuations in the concentration, low concentrations of circulating tumor DNA......, and different locations of methylation in the RASSF1A gene among patients. One common method for detection of hypermethylated genes is sodium bisulfite conversion of non-methylated cytosine to uracil, followed by detection with PCR. However, the method relies on full conversion of all non-methylated cytosines...... of the rare circulating tumor DNA was initially optimized. By analysis of production of PCR amplicons from HpaII- or BstUI-treated DNA isolated from 24 patients with metastatic breast cancer, we located four regions resulting in sensitivities from 63 to 83 %. When examining samples from 24 control subjects...

    average interassay CV was 6.4% for IgA and 4.3% for IgG (n=3. By defining a positive te st as both IgA and IgG elevated, a sensitivity of 93% in untreated coeliacs (n=75 was observed. The corresponding specificities in healthy adults (n=130 and healthy children (n=77 were >99% and 100% respectively, while in patients with other gastrointestinal disorders (disease controls the specificity was 94% (n=129. The test was also useful in monitoring patients, with anti-gliadin IgA and IgG falling for up to a year after commencing a gluten-free diet (GFD (12 adults. In some patients however, antibody levels did not reach the normal cutpoint after many months on a GFD, which may reflect the patients ' poor adherence to their gluten free diet. The test was superior to the Pharmacia anti-gliadin ELISA, and should be useful as an aid to the diagnosis of coeliac disease, as well as in the follow-up of treated patients.

    Full Text Available The study focused on the influence of a 9-week monitored energy deficit on serum leptin level in 16 obese women. Additionally, measurements of body components and total cholesterol (CHO, HDL cholesterol (HDL and triacylglycerols (TRG concentration in blood were carried out, concentration of LDL cholesterol (LDL was evaluated. Energy deficit was induced by a diet and “fat burning” type exercises. Leptin concentration in blood serum was significantly higher before (41.7±16.5 ng/ml than after the accomplishment of experiment (24.7±16.2 ng/ml. Body mass decreased, which was mainly due to a drop in body fat (from 36.6±13.9 kg to 29.0±12.5 kg. All changes have been statistically significant at the level of P<0.001. A significant decrease of CHO (from 187.9±26.3 mg/dl to 167.1±25.4 mg/dl; P<0.001 and LDL (from 115.5±25.1 mg/dl to 102.3±21.5 mg/dl; P<0.05 concentration in blood was noticed. However, changes in HDL and TRG concentration were statistically insignificant. There was a statistically significant correlation (P<0.05 recorded between changes in leptin concentration in blood and changes in body mass, BMI and body fat (0.51; 0.58; 0.64 respectively. No correlation was observed between leptin and lean body mass, CHO, HDL, LDL or TRG.

    Full Text Available Abstract Background The ABC transporter P-glycoprotein (P-gp is recognized as a site for drug-drug interactions and provides a mechanistic explanation for clinically relevant pharmacokinetic interactions with digoxin. The question of whether several P-gp inhibitors may have additive effects has not yet been addressed. Methods We evaluated the effects on serum concentrations of digoxin (S-digoxin in 618 patients undergoing therapeutic drug monitoring. P-gp inhibitors were classified as Class I, with a known effect on digoxin kinetics, or Class II, showing inhibition in vitro but no documented effect on digoxin kinetics in humans. Mean S-digoxin values were compared between groups of patients with different numbers of coadministered P-gp inhibitors by a univariate and a multivariate model, including the potential covariates age, sex, digoxin dose and total number of prescribed drugs. Results A large proportion (47% of the digoxin patients undergoing therapeutic drug monitoring had one or more P-gp inhibitor prescribed. In both univariate and multivariate analysis, S-digoxin increased in a stepwise fashion according to the number of coadministered P-gp inhibitors (all P values Conclusions Polypharmacy may lead to multiple drug-drug interactions at the same site, in this case P-gp. The S-digoxin levels increased in a stepwise fashion with an increasing number of coadministered P-gp inhibitors in patients taking P-gp inhibitors and digoxin concomitantly. As coadministration of digoxin and P-gp inhibitors is common, it is important to increase awareness about P-gp interactions among prescribing clinicians.

    Omega-3 polyunsaturated fatty acids (ω-3PUFAs) have inhibitory effects in various preclinical cancer models, but their effects in intestinal polyposis have never been examined. As attempts have been made to use nutritional intervention to counteract colon cancer development, in this study we evaluated the effects of ω-3 PUFAs on intestinal polyposis in the Apc(Min/+) mouse model. The experimental groups included wild-type C56BL/6 mice, Apc(Min/+) mice, fat-1 transgenic mice expressing an n-3 desaturase to enable ω-3 PUFA synthesis, and Apc(Min/+) × fat-1 double-transgenic mice; all mice were 20 weeks of age. Small intestines were collected for gross and pathologic evaluation, including assessment of polyp number and size, followed by immunohistochemical staining and Western blotting. After administration of various concentrations of ω-3 PUFAs, PUFA levels were measured in small intestine tissue by GC/MS/MS analysis to compare with PUFA synthesis of between C57BL6 and fat-1mice. As a result, ω-3 PUFAs significantly attenuated Apc mutation-induced intestinal polyposis accompanied with significant inhibition of Wnt/β-catenin signaling, COX-2 and PGE2, but induced significant levels of 15-PGDH. In addition, significant induction of the inflammasome-related substrates as IL-1β and IL-18 and activation of caspase-1 was observed in Apc(Min/+) × fat-1 mice. Administration of at least 3 g/60 kg ω-3 PUFAs was equivalent to ω-3 PUFAs produced in fat-1 mice and resulted in significant increase in the expression of IL-1β, caspase-3 and IL-18, as seen in Apc(Min/+) × fat-1 mice. We conclude that ω-3PUFAs can prevent intestinal polyp formation by inhibition of Wnt/β-catenin signaling, but increased levels of 15-PGDH and IL-18.

    To estimate the relationships between the serum concentrations of acute-phase proteins (APPs) and adipocytokines, body composition (BC), and blood glucose (BG) fluctuations in women with type 2 diabetes mellitus (T2DM). A total of 165 women with T2DM and 22 with a normal body mass index (BMI) at the age of 40 to 70 years were examined. The concentrations of high-sensitivity C-reactive protein (hs-CRP) and acid α1-glycoprotein (α1-AGP) were determined by ELISA. The levels of interleukins 6, 8, and 18 (IL-6, IL-8, IL-18), tumor necrosis factor-α (TNF-α), and plasminogen activator inhibitor type 1 (PAI-1) were measured by a multiplex analysis. Dual energy X-ray absorptiometry was used to estimate BC parameters. BG fluctuations were estimated via continuous glucose monitoring. The levels of hs-CRP, α1-AGP, IL-6, IL-8, IL-18, TNF-α, and PAI-1 were significantly higher in the obese women with T2DM than those in the control group. In the diabetic normal weight women, only hs-CRP, α1-AGP, and IL-8 concentrations exceeded those in the controls. The level of hs-CRP (other than α1-AGP) correlated positively with BMI, the mass of adipose tissue, body trunk (android), and gynoid fats. A multivariate regression analysis showed that adipose tissue mass and trunk fat proportion were independent predictors of hs-CRP levels. The concentrations of IL-6, IL-8, IL-18, PAI-1, and TNF-α correlated positively with waist-to-hip ratio, but demonstrated no associations with BMI and BC. Only the serum α1-AGP level showed a positive association with mean BG and its variability parameters. In the women with T2DM, the serum concentrations of APPs and adipocytokines correlate differently with the mass of adipose tissue, its distribution, and BG fluctuations. The findings indicate the multifactorial genesis of chronic inflammation in these patients.

    The goal of this study was to monitor imatinib mesylate therapeutically in the Tumor Biology Laboratory, Department of Hematology and Hemotherapy, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (USP). A simple and sensitive method to quantify imatinib and its metabolite (CGP74588) in human serum was developed and fully validated in order to monitor treatment compliance. The method used to quantify these compounds in serum included protein precipitation extraction followed by instrumental analysis using high performance liquid chromatography coupled with mass spectrometry. The method was validated for several parameters, including selectivity, precision, accuracy, recovery and linearity. The parameters evaluated during the validation stage exhibited satisfactory results based on the Food and Drug Administration and the Brazilian Health Surveillance Agency (ANVISA) guidelines for validating bioanalytical methods. These parameters also showed a linear correlation greater than 0.99 for the concentration range between 0.500 µg/mL and 10.0 µg/mL and a total analysis time of 13 minutes per sample. This study includes results (imatinib serum concentrations) for 308 samples from patients being treated with imatinib mesylate. The method developed in this study was successfully validated and is being efficiently used to measure imatinib concentrations in samples from chronic myeloid leukemia patients to check treatment compliance. The imatinib serum levels of patients achieving a major molecular response were significantly higher than those of patients who did not achieve this result. These results are thus consistent with published reports concerning other populations.

    Full Text Available Crohn's disease (CD and celiac disease (CelD are chronic intestinal inflammatory diseases, involving genetic and environmental factors in their pathogenesis. The two diseases can co-occur within families, and studies suggest that CelD patients have a higher risk to develop CD than the general population. These observations suggest that CD and CelD may share common genetic risk loci. Two such shared loci, IL18RAP and PTPN2, have already been identified independently in these two diseases. The aim of our study was to explicitly identify shared risk loci for these diseases by combining results from genome-wide association study (GWAS datasets of CD and CelD. Specifically, GWAS results from CelD (768 cases, 1,422 controls and CD (3,230 cases, 4,829 controls were combined in a meta-analysis. Nine independent regions had nominal association p-value <1.0 x 10⁻⁵ in this meta-analysis and showed evidence of association to the individual diseases in the original scans (p-value < 1 x 10⁻² in CelD and < 1 x 10⁻³ in CD. These include the two previously reported shared loci, IL18RAP and PTPN2, with p-values of 3.37 x 10⁻⁸ and 6.39 x 10⁻⁹, respectively, in the meta-analysis. The other seven had not been reported as shared loci and thus were tested in additional CelD (3,149 cases and 4,714 controls and CD (1,835 cases and 1,669 controls cohorts. Two of these loci, TAGAP and PUS10, showed significant evidence of replication (Bonferroni corrected p-values <0.0071 in the combined CelD and CD replication cohorts and were firmly established as shared risk loci of genome-wide significance, with overall combined p-values of 1.55 x 10⁻¹⁰ and 1.38 x 10⁻¹¹ respectively. Through a meta-analysis of GWAS data from CD and CelD, we have identified four shared risk loci: PTPN2, IL18RAP, TAGAP, and PUS10. The combined analysis of the two datasets provided the power, lacking in the individual GWAS for single diseases, to detect shared loci with a

    In patients with melanoma, early dissemination via lymphatic and hematogenous routes is frequently seen. Thus, besides clinical follow-up examination and imaging, reliable melanoma-specific serological tumor markers are needed. We retrospectively compared two serum markers for melanoma, S100 and melanoma-inhibitory activity (MIA), for monitoring of patients with metastatic melanoma under either adjuvant or therapeutic vaccination immunotherapy with dendritic cells (DC). Serum was obtained from a total of 100 patients (28 patients in stage III and 72 patients in stage IV, according to the American Joint Committee on Cancer 2002) at regular intervals during therapy, accompanied by follow-up imaging. When relapse was detected, both markers often remained within normal range. In contrast, in patients with metastatic measurable disease receiving therapeutic and not adjuvant DC vaccination, an increase of both markers was a strong indicator for disease progression. When comparing both markers in the whole study population, MIA showed a superior sensitivity to detect disease progression. S100 and MIA are highly sensitive tumor markers for monitoring of patients with melanoma with current metastases, but less sensitive for monitoring of tumor-free patients. In the current study, MIA had a slightly superior sensitivity to detect progressive disease compared to S100 and seems to be more useful in monitoring of patients with metastatic melanoma receiving immunotherapy.

    The aim of this research was to determine the association between interleukin-18 polymorphism and the risk of systemic lupus erythematosus (SLE). We identified all the publications about the association between interleukin-18 polymorphism and SLE by searching CNKI, Wanfang Data, CBM, PubMed, Embase and Web of Knowledge (published from January 1, 1997 to July 01, 2012), and evaluated the quality of all included studies. The data were analyzed by Stata 11.0 software, and 10 studies were included with 2 646 SLE patients and 2 761 healthy controls. The meta-analysis showed that SLE risk was significantly associated with -1297C allele and SLE risk (OR=1.388, 95% CI=1.242-1.551, P〈 0.001) and -607A allele (OR=1.158, 95% CI=1.014-1.322, P=0.031) in European origin populations. Moreover, in European origin populations there was significant difference between SLE patients and healthy controls in the genotype of -1297 CC+CT versus TT (OR=1.353, 95% CI=1.174 -1.561, P〈 0.001) and CC versus CT+TT (OR =2.216, 95% CI=1.695-2.898, P〈 0.001). However, -607A allele decreased SLE risk in Chinese population (OR=0.606, 95% CI=0.396-0.930, P〈 0.001). This meta-analysis supported that the IL-18 -1297C/T and -607C/A polymorphism is associated with SLE susceptibility in European origin populations, while -607A allele may be a protective factor in Chinese population.%目的 评价IL-18基因多态性与系统性红斑狼疮(systemic lupus erythematosus,SLE)的关系.方法检索中国学术期刊全文数据库(CNKI)、万方数据库、中国生物医学文献数据库(CBM)、PubMed、Embase和Web of Knowledge数据库,检索时间范围为1997年01月01日至2012年07月01日.按照纳入和排除标准纳入合格文献,并对其进行质量评价,用Stata 11.0软件进行Meta分析.结果 共纳入10篇文献,收集到2 646例病例,2 761例对照,Meta分析结果显示欧裔人群中的IL-18-1297C/T (OR=1.388,95% CI=1.242~1.551,P<0.001)和-607A/C(OR=1.158,95% CI=1.014

    Therapeutic drug monitoring is a common practice in clinical studies. It requires the quantification of drugs in biological fluids. Micellar liquid chromatography (MLC), a well-established branch of Reverse Phase-High Performance Liquid Chromatography (RP-HPLC), has been proven by many researchers as a useful tool for the analysis of these matrices. This review presents several analytical methods, taken from the literature, devoted to the determination of several monitorable drugs in serum and urine by micellar liquid chromatography. The studied groups are: anticonvulsants, antiarrhythmics, tricyclic antidepressants, selective serotonin reuptake inhibitors, analgesics and bronchodilators. We detail the optimization strategy of the sample preparation and the main chromatographic conditions, such as the type of column, mobile phase composition (surfactant, organic solvent and pH), and detection. The finally selected experimental parameters, the validation, and some applications have also been described. In addition, their performances and advantages have been discussed. The main ones were the possibility of direct injection, and the efficient chromatographic elution, in spite of the complexity of the biological fluids. For each substance, the measured concentrations were accurate and precise at their respective therapeutic range. It was found that the MLC-procedures are fast, simple, inexpensive, ecofriendly, safe, selective, enough sensitive and reliable. Therefore, they represent an excellent alternative for the determination of drugs in serum and urine for monitoring purposes.

It has become the ideal tyrosine kinase inhibitor and the standard treatment for chronic-phase leukemia. Striking results have recently been reported, but intolerance to imatinib and noncompliance with treatment remain to be solved. Molecular monitoring by quantitative real-time polymerase chain reaction is the gold standard for monitoring patients, and imatinib blood levels have also become an important tool for monitoring.Methods: A fast and cheap method was developed and validated using high-performance liquid chromatography-mass spectrometry for quantification of imatinib in human serum and tamsulosin as the internal standard. Remarkable advantages of the method includes use of serum instead of plasma, less time spent on processing and analysis, simpler procedures, and requiring reduced amounts of biological material, solvents, and reagents. Stability of the analyte was also studied. This research also intended to drive the validation scheme in clinical centers. The method was validated according to the requirements of the US Food and Drug Administration and Brazilian National Health Surveillance Agency within the range of 0.500–10.0 µg/mL with a limit of detection of 0.155 µg/mL. Stability data for the analyte are also presented.Conclusion: Given that the validated method has proved to be linear, accurate, precise, and robust, it is suitable for pharmacokinetic assays, such as bioavailability and bioequivalence, and is being successfully applied in routine therapeutic drug monitoring in the hospital service.Keywords: imatinib, high-performance liquid chromatography-mass spectrometry, therapeutic

    Autologous serum skin test (ASST) is mostly used in chronic spontaneous urticaria (CSU) to show autoreactivity. Interleukin-18 (IL-18) has also been shown to be involved in autoimmune conditions. To investigate the role of autoreactivity assessed by ASST in CSU and respiratory diseases and to investigate whether this autoreactive state is related to IL-18 level or other clinical covariates. Fifty-five patients with CSU (mean age: 40.3 ± 12.3 years), 70 patients with persistent asthma (mean age: 43.7 ± 9.6 years), 21 patients with seasonal allergic rhinitis (SAR) (mean age: 35.5 ± 11.8 years) and 20 normal controls (mean age: 37.7 ± 9.8) were included. All subjects underwent a laboratory examination and skin prick test. ASST was performed and serum IL-18 levels were measured in all subjects. Positive response to ASST and serum IL-18 levels were higher in CSU patients than those with respiratory diseases (asthma and SAR) (P = 0.034 and 0.002, respectively) and normal controls (P = 0.004 and 0.031, respectively). Considering all patients, IL-18 levels were higher in patients with positive ASST (301.8 ± 194.4 vs. 241.8 ± 206.3 pg/ml, P = 0.036) than ASST negative patients. ASST response was associated with disease severity in CSU (P = 0.037) and asthma patients (P = 0.001). Multivariate analysis showed that positive response to ASST was significantly associated with diagnosis of CSU (OR: 3.13, 95% CI: 1.25-7.87) and female gender (OR: 3.98, 95% CI: 1.19-13.38). ASST response could be related with activity of the disease. A positive ASST response found in respiratory diseases patients suggests that it may occur as a result of some inflammatory events during the diseases' process.

    Elevated serum total cholesterol is a major and modifiable risk factor for heart disease, the lead-ing cause of death in the United States (1,2). Reducing mean total serum cholesterol levels among adults to less than 200 mg/dL and reducing the proportion who have levels of 240 mg/dL or higher to less than 17% are national Healthy People 2010 objectives (3). Age-adjusted mean serum cholesterol levels among adults aged 20-74 years declined from 222 mg/dL in 1960-1962 to 203 mg/dL in 1999-2002 (4). Among adults aged 20 years and older, the percent of the population with high serum total cholesterol levels (240 mg/dL or higher) declined from 20% during 1988-1994 to 17% during 1999-2002 (4). In individual patients, a high serum total cholesterol level indicates a potential increased risk for heart disease, but further evaluation of other risk factors and the specific components of cholesterol provide the basis for determining the need for initiating therapeutic lifestyle changes or treatment with medication (5). Low-density-lipoprotein (LDL) is the cholesterol component associated with arterial blockage, and it is the primary clinical target for cholesterol management. High-density-lipoprotein (HDL) may help to protect individuals from developing heart disease. In populations, comparisons of total cholesterol levels over time can show if population groups are experiencing improvement in cholesterol levels, and knowledge of trends in levels of total cholesterol can help identify subgroups where additional prevention efforts may be needed.

    The influence of the inclusion of a stable isotopic labeled internal standard (SIL-IS) on the quantitative analysis of hydroxyeicosatetranoic acids (HETEs) in human serum is evaluated in this research. A solid-phase extraction-liquid chromatography-tandem mass spectrometry (SPE-LC-MS/MS) platform, one of the preferred approaches for targeted analysis of biofluids through the selected reaction monitoring (SRM) operational mode, was used to determine HETEs. These compounds were chosen as targeted metabolites because of their involvement in cardiovascular disease, cancer and osteoporosis. 15HETE-d8 was chosen as internal standard to evaluate matrix effects. Thus, the physico-chemical properties of the SIL-IS were the basis to evaluate the analytical features of the method for each metabolite through four calibration models. Two of the models were built with standard solutions at different concentration levels, but one of the calibration sets was spiked with an internal standard (IS). The other two models were built with the serum pool from osteoporotic patients, which was spiked at different concentrations with the target analytes. In this case, one of the serum calibration sets was also spiked with the IS. The study shows that the IS allowed noticeable correction of matrix effects for some HETE isomers at certain concentration levels, while accuracy was decreased at low concentration (15ng/mL) of them. Therefore, characterization of the method has been properly completed at different concentration levels. Copyright © 2014 Elsevier B.V. All rights reserved.

    The serological protein tumor markers CA 15-3, CEA, and TPA are frequently used to monitor tumor burden among metastatic breast cancer patients. Breast cancer is associated with global DNA hypomethylation and hypermethylation of some promoter regions. No monitoring study has yet investigated the interrelationship between protein tumor markers, the global DNA hypomethylation, and hypermethylated genes in serum from patients with advanced disease. Twenty-nine patients with histologically proven advanced breast cancer received first-line chemotherapy with epirubicin. Samples were collected prior to each treatment and prospectively analyzed for CA 15-3, CEA, and TPA. The same samples were retrospectively analyzed for the concentration of hypermethylated RASSF1A and for global DNA hypomethylation using LINE-1. Among patients with elevated concentrations of the protein markers, concordance could be observed between serial changes of the hypermethylated RASSF1A gene and the protein markers. Among patients with lower concentrations, RASSF1A could only be detected periodically. There was discordance between changes of the hypomethylated LINE-1 as compared to the protein markers. Circulating hypermethylated RASSF1A and protein markers may have similar kinetics during monitoring of tumor burden. Further investigations are needed to determine whether any of the hypermethylated DNA genes may provide predictive information during monitoring.

    AIM: To evaluate prospectively 4 selected serum fibrosis markers (tenascin, hyaluronan, collagen Ⅵ, TIMP-1)before, during and 12 mo after IFN treatment of children with chronic hepatitis B.METHODS: Forty-seven consecutive patients wit-h chronic hepatitis B (range 4-16 years, mean 8 years) underwent IFN treatment (3 MU tiw for 20 wk). Fibrosis stage and inflammation grade were assessed in a blinded fashion before and 12 mo after end of treatment. Serum fibrosis markers were determined using automated assays.RESULTS: IFN treatment improved histological inflammation but did not change fibrosis in the whole group or in subgroups. Only hyaluronan correlated significantly with histological fibrosis(r = 0.3383, P = 0.021).Basal fibrosis markers did not differ between responders (42.5%) and nonresponders(57.5% ). During IFN treatment only serum tenascin decreased significantly in the whole group and in nonresponders. When pretreatment values were compared to values 12 mo after therapy, TIMP-1 increased in all patients and in nonresponders, and hyaluronan decreased in all patients and in responders.CONCLUSION: Tenascin reflects hepatic fibrogenesis and inflammation which decreases during IFN treatment of children with chronic hepatitis B. TIMP-1 correlates with nonresponse and hyaluronan with histological fibrosis.

    Full Text Available Adile Ortakoyluoglu, Betul Boz, Oguzhan Sitki Dizdar, Deniz Avci, Ali Cetinkaya, Osman Baspinar Department of Internal Medicine, Kayseri Training and Research Hospital, Kayseri, Turkey Background: Hypertension is a very important cause of morbidity and mortality. Serum gamma-glutamyl transpeptidase (GGT is a biomarker of oxidative stress and associated with increased risk of hypertension and diabetes. The aim of this study was to evaluate the association of serum GGT level, which is an early marker of inflammation and endothelial dysfunction, with the deterioration of the diurnal rhythm of the blood pressure.Methods: A total of 171 patients with hypertension were included in this study. Patients whose nighttime mean blood pressure, measured via ambulatory blood pressure monitoring, decreased between 10% and 20% compared with the daytime mean blood pressure were defined as “dippers”, whereas patients with a nighttime blood pressure decrease lower than 10% were defined as “non-dippers”.Results: A total of 99 hypertensive patients (65 females/34 males were classified as dippers and 72 patients (48 females/24 males as non-dippers. The mean age of the non-dipper group was significantly greater than the dipper group. Serum GGT, C-reactive protein and uric acid levels were significantly higher among patients in the non-dipper group. Negative correlations were detected between GGT levels and diurnal systolic and diastolic blood pressure decreases.Conclusion: Our findings revealed that GGT level was higher in the non-dipper group, and was negatively correlated with the nighttime decrease of diurnal blood pressure. C-reactive protein and uric acid levels were also higher in the non-dipper group. However, future randomized controlled prospective studies with larger patient populations are necessary to confirm our findings.

    A method is presented to quantify intermediate-abundance proteins in human serum using a single-quadrupole linear ion trap mass spectrometer-in contrast, for example, to a triple-quadrupole mass spectrometer. Stable-isotope-labeled (tryptic) peptides are spiked into digested protein samples as internal standards, aligned with the traditional isotope dilution approach. As a proof-of-concept experiment, four proteins of intermediate abundance were selected, coagulation factor V, adiponectin, C-reactive protein (CRP), and thyroxine binding globulin. Stable-isotope-labeled peptides were synthesized with one tryptic sequence from each of these proteins. The normal human serum concentration ranges of these proteins are from 1 to 30 microg/mL (or 20 to 650 pmol/mL). These labeled peptides and their endogenous counterparts were analyzed by LC-MS/MS using multiple reaction monitoring, a multiplexed form of the selected reaction monitoring technique. For these experiments, only one chromatographic dimension (on-line reversed-phase capillary column) was used. Improved limits of detection will result with multidimensional chromatographic methods utilizing more material per sample. Standard curves of the spiked calibrants were generated with concentrations ranging from 3 to 700 pmol/mL using both neat solutions and peptides spiked into the complex matrix of digested serum protein solution where ion suppression effects and interferences are common. Endogenous protein concentrations were determined by comparing MS/MS peak areas of the endogenous peptides to the isotopically labeled internal calibrants. The derived concentrations from a normal human serum pool (neglecting loss of material during sample processing) were 9.2, 110, 120, and 246 pmol/mL for coagulation factor V, adiponectin, CRP, and thyroxine binding globulin, respectively. These concentrations generally agree with the reported normal ranges for these proteins. As a measure of analytical reproducibility of this

    Abstract Behcet's disease (BD) is a multisystemic disorder of unknown etiology characterized by relapsing oral–genital ulcers, uveitis, and involvement of vascular, gastrointestinal, neurological, and musculoskeletal system. Although disease pathogenesis is still unclear, both innate and adaptive immunity have shown to play a pivotal role, and multiple proinflammatory cytokines seem to be involved in different pathogenic pathways that eventually lead to tissue damage. The aims of our study were to evaluate serum cytokines levels of IL-8, IL-18, IFN-α2a, IL-6, IFN-γ, CXCL10, CXCL11, CXCL9, and SAA levels in patients with BD, in comparison to healthy controls (HC), and to correlate their levels to disease activity. We included 78 serum samples obtained from 58 BD patients and analyzed a set of proinflammatory cytokines including IL-8, IL-18, IFN-α2a, IL-6, IFN-γ, CXCL10, CXCL11, and CXCL9 by multiplex bead analysis as well as SAA by enzyme-linked immunosorbent assay. Compared to HC, BD patients showed elevated cytokine levels of IL-8, IL-18, IFN-α2a, and IL-6, and low levels of CXCL11. BD patients with SAA serum levels >20 mg/L showed higher levels of proinflammatory markers than HC or group with SAA ≤20 mg/L. IL-18, IFN-α2a, and IL-6 were higher in BD group with SAA >20 mg/L than HC, while IL-8 and CXCL9 levels were higher than in patients with SAA ≤20 mg/L and HC. Active BD patients with SAA >20 mg/L exhibited elevated levels of inflammatory mediators, suggesting that may exist a relationship between SAA and proinflammatory cytokines in the intricate scenario of BD pathogenesis.

    Urine cystein proteinase (UCP) and serum CA125 were measured in 40 patients with malignant ovarian tumor (malignant group), 40 patients with benign ovarian tumor (benign group), and 40 normal control (normal group). 28 patients in the malignant group underwent UCP and CA125 measurement pre-operation, post-operation, and during three courses of chemotherapy. The enzyme activity of UCP in the malignant group was significantly higher than that in the benign and normal groups (P 2 cm in diameter were apparantly higher than those with no residual lesions (P < 0.05). UCP and CA125 values were measured in six patients before relaparotomy. The sensitivity, specificity, accuaracy, positive predictive value and negative predictive value for UCP assay are 980%, 100%, 83%, 100% and 50% and those for CA125 assay are 40%, 100%, 80%, 100%, and 25%, respectively.

    Full Text Available Angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs are commonly used in patients with chronic kidney disease (CKD. We studied the status of ACEI/ARB prescriptions and serum creatinine (Scr and potassium monitoring in CKD patients. A retrospective observational study was conducted on patients who had at least two sets of Scr data at outpatient visit. Estimated glomerular filtration rate (eGFR based on the second Scr value was calculated using the Modification of Diet in Renal Disease four-variable equation. CKD was defined and staged according to the National Kidney Foundation Disease Outcomes Quality Initiative Guideline. Patients with diabetes and/or hypertension with an eGFR over 60 mL/min/1.73 m2 and without proteinuria were defined as the CKD-at-risk group. The percentages and factors associated with ACEI/ARB prescription and Scr and potassium monitoring were calculated and analyzed by logistic regression. Among the 5714 subjects included, ACEIs/ARBs were prescribed to over 50% of patients in the CKD-at-risk group and in CKD stages 1–5. After adjusting for age, sex, potassium level, eGFR, and co-morbidities, the odds ratios for prescriptions of ACEIs/ARBs were 1.66 [95% confidence interval (CI 1.44–1.91, p < 0.001 and 2.80 (95% CI 2.12–3.70, p < 0.001 in CKD stage 3, and stages 4 and 5, respectively, compared with the reference group (eGFR≥60 mL/min/1.73 m2. During the year of ACEI/ARB treatment, Scr was monitored in 91.6% of ACEI/ARB-treated patients, while potassium was monitored in only 38.1%. Renal function status was the independent factor for monitoring of Scr and potassium. In conclusion, prescription of ACEIs/ARBs was common in all stages of CKD. Most patients underwent Scr monitoring, but potassium monitoring was less frequent, and this should be improved in clinical practice.

    The detection of testosterone abuse in sports is routinely achieved through the 'steroidal module' of the Athlete Biological Passport by GC-MS(/MS) quantification of selected endogenous anabolic androgenic steroids (EAAS) from athletes' urines. To overcome some limitations of the "urinary steroid profile" such as the presence of confounding factors (ethnicity, enzyme polymorphism, bacterial contamination, and ethanol), ultrahigh performance liquid chromatography (UHPLC) measurements of blood concentrations of testosterone, its major metabolites, and precursors could represent an interesting and complementary strategy. In this work, two UHPLC-MS/MS methods were developed for the quantification of testosterone and related compounds in human serum, including major progestogens, corticoids, and estrogens. The validated methods were then used for the analyses of serum samples collected from 19 healthy male volunteers after oral and transdermal testosterone administration. Results from unsupervised multiway analysis allowed variations of target analytes to be assessed simultaneously over a 96-h time period. Except for alteration of concentration values due to the circadian rhythm, which concerns mainly corticosteroids, DHEA, and progesterone, significant variations linked to the oral and transdermal testosterone administration were observed for testosterone, DHT, and androstenedione. As a second step of analysis, the longitudinal monitoring of these biomarkers using intra-individual thresholds showed, in comparison to urine, significant improvements in the detection of testosterone administration, especially for volunteers with del/del genotype for phase II UGT2B17 enzyme, not sensitive to the main urinary marker, T/E ratio. A substantial extension of the detection window after transdermal testosterone administration was also observed in serum matrix. The longitudinal follow-up proposed in this study represents a first example of 'blood steroid profile' in doping control

    The authors evaluated the relationship of hypertensive target organ damage to masked hypertension assessed by ambulatory blood pressure (BP) and home blood pressure (HBP) monitoring in 129 participants without taking antihypertensive medication. Masked hypertension was defined as office BP ≤140/90 mm Hg and 24-hour ambulatory BP ≥130/80 mm Hg. The masked hypertensive participants defined by 24-hour ambulatory BP (n=13) had a higher serum glucose level (126 vs 96 mg/dL, P=.001) and urinary albumin-creatinine ratio (38.0 vs 7.5 mg/gCr, P<.001) than the normotensive participants (n=74); however, these relationships were not observed when the authors defined groups using HBP (≥135/85 mm Hg). Masked hypertension by both 24-hour ambulatory BP and HBP had a higher urinary albumin-creatinine ratio than normotension by both 24-hour ambulatory BP and HBP (62.1 vs 7.4 mg/gCr, P=.001), and than masked hypertension by HBP alone (9.3 mg/gCr, P=.009). Masked hypertension defined by 24-hour ambulatory BP is associated with an increased serum glucose level and urinary albumin-creatinine ratio, but these relationships are not observed in masked hypertension defined by HBP.

    Weekly serum beta-hCG measurements and transvaginal ultrasound scans coupled with color Doppler flow were performed on 8 patients with hydatidiform mole. Two patients later developed persistent trophoblastic disease, necessitating chemotherapy. The correlation coefficients between Doppler flow indices, systolic-diastolic (S/D) ratio and pulsatility index (PI) with log beta-hCG were -0.96 and -0.97, respectively. The weekly S/D and PI indices were plotted on an individual curve. Only the 2 patients who developed persistent gestational trophoblastic disease had PI index levels of < or = 1.5 as early as 2 weeks after molar evacuation. At that stage their serum beta-hCG levels were not different from some of the other patients. In this preliminary report, the regression of the disease could be reliably assessed by observing the changes in low resistance flow which paralleled the gradual decrements in serial beta-hCG levels. Thus, the contribution of this noninvasive imaging technique encourages the authors to further investigate Doppler flow monitoring among a larger sample of patients suffering from various gestational trophoblastic diseases.

    Using a novel noninvasive, visible-light optical diffusion oximeter (T-Stat VLS Tissue Oximeter; Spectros Corporation, Portola Valley, CA) to measure the tissue oxygen saturation (StO2) of the buccal mucosa, the correlation between StOz and central venous oxygen saturation (ScvO2) was examined in children with congenital cyanotic heart disease undergoing a cardiac surgical procedure. Paired StO2 and serum ScvO2 measurements were obtained postoperatively and statistically analyzed for agreement and association. Thirteen children (nine male) participated in the study (age range, 4 days to 18 months). Surgeries included Glenn shunt procedures, Norwood procedures, unifocalization procedures with Blalock-Taussig shunt placement, a Kawashima/ Glenn shunt procedure, a Blalock-Taussig shunt placement, and a modified Norwood procedure. A total of 45 paired StO2-ScvO2 measurements was obtained. Linear regression demonstrated a Pearson's correlation of .58 (95% confidence interval [CI], .35-.75; p < .0001). The regression slope coefficient estimate was .95 (95% CI, .54-1.36) with an interclass correlation coefficient of .48 (95% CI, .22-.68). Below a clinically relevant average ScvO2 value, a receiver operator characteristic analysis yielded an area under the curve of .78. Statistical methods to control for repeatedly measuring the same subjects produced similar results. This study shows a moderate relationship and agreement between StO2 and ScvO2 measurements in pediatric patients with a history of congenital cyanotic heart disease undergoing a cardiac surgical procedure. This real-time monitoring device can act as a valuable adjunct to standard noninvasive monitoring in which serum SyvO2 sampling currently assists in the diagnosis of low cardiac output after pediatric cardiac surgery.

    Full Text Available The present study was carried out on 30 patients with systemic lupus erythematosus (SLE and ten apparently healthy individuals as a control group.Systemic lupus erythematosus activity index (SLEDAI was applied to all patients. Anti-double stranded DNA antibodies (Anti-dsDNA Abs. , interleukin-18 (IL-18 and soluble CD95 (Apo-1/Fas were determined in the sera of all studied subjects. The mean ±SD SLEDAI in all patients was 15.25± 6.76 . The anti-dsDNA antibodies was positive in all studied patients (mean ± SD 264.36 ± 114.85 IU/ml. Serum IL-18 showed significant elevation in SLE patients as compared to the control group (Mean ±SD 246.13± 114.32I U/ml vs. 45.5 ± 7.32 IU/ml ; p < 0.001. Serum Soluble CD95 (sCD95showed significant increase in all SLE patients as compared to the control group (Mean±SD 648±116.96 pg/ml vs. 270±50.24 pg/ml ;p < 0.001. Serum sCD95 also showed significant rise in SLE patients with moderate activity as compared to those with mild activity (Mean ± SD 629.16± 72.54 pg/ml vs. 535 ±35.97 pg/ml; p<0.05. The serum level of sCD95 in SLE cases with severe activity showed significant increase when compared to those with moderate activity ( Mean±SD 797.5 ± 41.66 pg/ml vs. 629.16 ± 72.54 pg/ml ; p <0.001. Anti-dsDNA antibodies showed significant positive correlation with SLEDAI (r=0.772;p<0.01. IL-18 also showed a significant positive correlation with the SLEDAI (r=0.670 ;p<0.01. Soluble CD95 showed significant positive correlation with SLDAI (r=0.865 ; p<0.01, with anti-dsDNA antibodies (r=0.775 ;p<0.01 and with IL-18 (r =0.722 ; p<0.01. From these results it was concluded that serum sCD95 is increased in patients with systemic lupus erythematosus and it is correlated with anti-dsDNA antibodies , with IL-18 and with the disease activity, so it can be useful marker of disease activity for proper management and follow up of SLE patients.

    Mucormycosis is a fatal complication in immunocompromised patients, and is additionally difficult to diagnose due to the lack of useful serum biomarkers. Using a quantitative PCR approach, we retrospectively analyzed Mucorales DNA load in sera collected serially from a 3-year-old patient with chronic granulomatous disease, who died of multi-organ failure probably due to dissemination of Rhizomucor pusillus, which was detected from necropsy specimens. Mucorales DNA load was below the detection limit on days 9, 2, and 4 after unrelated bone marrow transplantation. Rhizomucor DNA was first detected on day 14 (1.6 × 10(3) copies/mL), and subsequently fluctuated between 1.3 × 10(3) and 37.2 × 10(3) copies/mL until day 43. Rhizomucor achieved a peak value of 940.0 × 10(3) copies/mL on day 48 the day before death. The detection or fluctuation of Rhizomucor DNA appeared to be associated with corticosteroid dosages or C-reactive protein levels. This specific, noninvasive, and highly quantitative assay may be useful for the early diagnosis of mucormycosis and prediction of disease progression.

    Bio-decontamination of surfaces by means of atmospheric pressure plasma is nowadays extensively studied as it represents promising alternative to commonly used sterilization/decontamination techniques. The non-equilibrium atmospheric pressure plasmas were already reported to be highly effective in removal of a wide range of biological residual from surfaces. Nevertheless the kinetics of removal of biological contamination from surfaces is still not well understood as the majority of performed studies were based on ex-situ evaluation of etching rates, which did not allow investigating details of plasma action on biomolecules. This study therefore presents a real-time, in-situ ellipsometric characterization of removal of bovine serum albumin (BSA) from surfaces by low-temperature atmospheric plasma jet operated in argon. Non-linear and at shorter distances between treated samples and nozzle of the plasma jet also non-monotonic dependence of the removal rate on the treatment duration was observed. According to additional measurements focused on the determination of chemical changes of treated BSA as well as temperature measurements, the observed behavior is most likely connected with two opposing effects: the formation of a thin layer on the top of BSA deposit enriched in inorganic compounds, whose presence causes a gradual decrease of removal efficiency, and slight heating of BSA that facilitates its degradation and volatilization induced by chemically active radicals produced by the plasma.

    Full Text Available ObjectiveTo explore the clinical value of three serum tumor markers, Golgi protein 73 (GP73, alpha-fetoprotein (AFP, and AFP-L3, in the diagnosis of liver cancer and recurrence monitoring after radio frequency ablation. MethodsA total of 174 patients who visited our hospital from July 2012 to October 2013 were included in the study, consisting of 86 patients with newly diagnosed liver cancer, 39 with liver cirrhosis, 29 with hepatitis, and 20 healthy controls. Among the patients with newly diagnosed liver cancer, 37 were followed up for three months after the radiofrequency ablation. Serum levels of GP73, AFP, and AFP-L3 were measured by ELISA, electrochemiluminescence, and affinity adsorption chromatography, respectively. Nonparametric tests were performed on the results of serum samples from the four groups which showed skewed distribution and were represented by median (quartile interval [M(P25-P75]. Overall comparison was made by Kruskal-Wallis H test, and comparison between groups was made by Mann-Whitney U test. Pair-matching rank-sum test was performed using Wilcoxon Signed Ranks, and categorical data were analyzed by χ2 test. ResultsThe levels of GP73, AFP, and AFP-L3 in the liver cancer group were significantly higher than those in other groups (all P<0.05. The positive rates of GP73 and AFP-L3 in the liver cancer group were significantly higher than those in other groups (all P<0.05, and the positive rates of the two markers were significantly higher than that of AFP among patients with liver cancer (P<0.05. Thirty-seven patients with newly diagnosed liver cancer were reexamined three months after radiofrequency ablation, and the preoperational AFP-L3 level in the patients who had recurrence was significantly higher than that in the patients without recurrence (P<0.05. ConclusionSerum GP73, AFP, and AFP-L3 show great values in the diagnosis of liver cancer. AFP-L3 can be used as an indicator for the identification of

    Cytokine profiles may impact the pathogenicity and severity of hand, foot, and mouth disease caused by human enterovirus (HEV) 71. In 91 severe or mild HEV 71-associated hand, foot, and mouth disease children, serum was collected between days 2 and 10 or day >10. Serum cytokines including Type 1 T helper (Th1) cytokines: interleukin (IL)-2, interferon-gamma (IFN-γ), IL-12, and IL-18, Type 1 T helper (Th2) cytokines: IL-4, IL-10, IL-13, proinflammatory cytokines: IL-1α, IL-1β, IL-6, IL-8, IL-17, and tumor necrosis factor alpha (TNF-α), were assessed during the early stage and recovery. In the patients with mild illness, the peaks of IL-8 and IL-10 were observed on day 6 and that of IL-18 was on day 4. In the patients with severe illness, all cytokines spiked on day 3 and peaked on day 11. All cytokines except IL-6, IL-8, IL-18, and TNF-α were significantly correlated with immunoglobulin M levels by the end of the disease course.

    Rheumatoid arthritis is a chronic autoimmune-based inflammatory disease that leads to progressive joint degeneration, disability, and an increased risk of cardiovascular complications, which is the main cause of mortality in this population of patients. Although several biomarkers are routinely used in the management of rheumatoid arthritis, there is a high demand for novel biomarkers to further improve the early diagnosis of rheumatoid arthritis, stratification of patients, and the prediction of a better response to a specific therapy. In this study, the metabolomics approach was used to provide relevant biomarkers to improve diagnostic accuracy, define prognosis and predict and monitor treatment efficacy. The results indicated that twelve metabolites were important for the discrimination of healthy control and rheumatoid arthritis. Notably, valine, isoleucine, lactate, alanine, creatinine, GPC  APC and histidine relative levels were lower in rheumatoid arthritis, whereas 3-hydroxyisobutyrate, acetate, NAC, acetoacetate and acetone relative levels were higher. Simultaneously, the analysis of the concentration of metabolites in rheumatoid arthritis and 3 months after induction treatment revealed that L1, 3-hydroxyisobutyrate, lysine, L5, acetoacetate, creatine, GPC+APC, histidine and phenylalanine were elevated in RA, whereas leucine, acetate, betaine and formate were lower. Additionally, metabolomics tools were employed to discriminate between patients with different IL-17A genotypes. Metabolomics may provide relevant biomarkers to improve diagnostic accuracy, define prognosis and predict and monitor treatment efficacy in rheumatoid arthritis.

    Enzymatically-induced degradation of bovine serum albumin (BSA) by serine proteases (trypsin and α-chymotrypsin) in various concentrations was monitored by means of Fourier transform infrared (FT-IR) and ultraviolet circular dichroism (UV-CD) spectroscopy. In this study, the applicability of both spectroscopies to monitor the proteolysis process in real time has been proven, by tracking the spectral changes together with secondary structure analysis of BSA as proteolysis proceeds. On the basis of the FTIR spectra and the changes in the amide I band region, we suggest the progression of proteolysis process via conversion of α-helices (1654 cm- 1) into unordered structures and an increase in the concentration of free carboxylates (absorption of 1593 and 1402 cm- 1). For the first time, the correlation between the degree of hydrolysis and the concentration of carboxylic groups measured by FTIR spectroscopy was revealed as well. The far UV-CD spectra together with their secondary structure analysis suggest that the α-helical content decreases concomitant with an increase in the unordered structure. Both spectroscopic techniques also demonstrate that there are similar but less spectral changes of BSA for the trypsin attack than for α-chymotrypsin although the substrate/enzyme ratio is taken the same.

    Cefepime monitoring in deproteinized human serum and plasma by micellar electrokinetic capillary chromatography and liquid chromatography coupled to mass spectrometry in presence of other drugs is reported. For micellar electrokinetic capillary chromatography, sample preparation comprised dodecylsulfate protein precipitation at pH 4.5 using an increased buffer concentration compared to that of a previous assay and removal of hydrophobic compounds with dichloromethane. This provided robust conditions for cefepime analysis in the presence of sulfamethoxazole and thus enabled its determination in samples of patients that receive co-trimoxazole. The liquid chromatography assay is based upon use of a column with a pentafluorophenyl-propyl modified and multi-endcapped stationary phase and the coupling to electrospray ionization with a single quadrupole detector. The performances of both assays with multi-level internal calibration were assessed with calibration and control samples and both assays were determined to be robust. Cefepime levels monitored by micellar electrokinetic capillary chromatography in samples from patients that were treated with cefepime only and with cefepime and co-trimoxazole were found to compare well with those obtained by liquid chromatography coupled to mass spectrometry. Cefepime drug levels determined by micellar electrokinetic capillary chromatography could thereby be validated. This article is protected by copyright. All rights reserved.

    Imaging guided techniques have been increasingly employed to investigate the pharmacokinetics (PK) and biodistribution of nanoparticle based drug delivery systems. In most cases, however, the PK profiles of drugs could vary significantly from those of drug delivery carriers upon administration in the blood circulation, which complicates the interpretation of image findings. Herein we applied a genetically encoded luciferase reporter in conjunction with near infrared (NIR) fluorophores to investigate the respective PK profiles of a drug and its carrier in a biodegradable drug delivery system. In this system, a prototype hydrophobic agent, rapamycin (Rapa), was encapsulated into human serum albumin (HSA) to form HSA Rapa nanoparticles, which were then labeled with Cy5 fluorophore to facilitate the fluorescence imaging of HSA carrier. Meanwhile, we employed transgenetic HN12 cells that were modified with a split luciferase reporter, whose bioluminescence function is regulated by Rapa, to reflect the PK profile of the encapsulated agent. It was interesting to discover that there existed an obvious inconsistency of PK behaviors between HSA carrier and rapamycin in vitro and in vivo through near infrared fluorescence imaging (NIFRI) and bioluminescence imaging (BLI) after treatment with Cy5 labeled HSA Rapa. Nevertheless, HSA Rapa nanoparticles manifested favorable in vivo PK and tumor suppression efficacy in a follow-up therapeutic study. The developed strategy of combining a molecular reporter and a fluorophore in this study could be extended to other drug delivery systems to provide profound insights for non-invasive real-time evaluation of PK profiles of drug-loaded nanoparticles in pre-clinical studies.Imaging guided techniques have been increasingly employed to investigate the pharmacokinetics (PK) and biodistribution of nanoparticle based drug delivery systems.

    Objective: To study the correlation of serum monocyte chemotactant protein-1 (MCP-1) and vascular endothelia cadherin (VE-cadherin) levels in patients with acute cerebral infarction, and nerve injury molecules, interleukins and matrix metalloproteinases. Methods: A total of 86 patients with acute cerebral infarction treated in our hospital from April 2012 to October 2015 were selected as the observation group and 50 healthy subjects in the same period treated in our hospital were selected as the control group. The serums were collected and the contents of MCP-1, VE-cadherin, heart-type fatty acid binding protein (H-FABP), S100 calcium binding protein B (S100B), neuron-specific enolase (NSE), interleukin-lb (IL-1b), IL-6, IL-17, IL-18, matrix metalloproteinase-2 (MMP2), MMP3 and MMP9 were measured. Results: The serum contents of MCP-1, VE-cadherin, H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 in observation group were significantly higher than those of control group. Carotid artery plaque formation and unstable plaque properties will increase the serum contents of MCP-1, VE-cadherin, H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 in patients with cerebral infarction. The serum levels of MCP-1, VE-cadherin and the contents of H-FABP, S100B, NSE, IL-1b, IL-6, IL-17, IL-18, MMP2, MMP3 and MMP9 were positively correlated. Conclusions: The serum levels of VE-cadherin and MCP-1 were significantly increased in patients with acute cerebral infarction. MCP-1 and VE-cadherin can increase the secretion of interleukins and matrix metalloproteinases, which can result in the carotid artery plaque formation, unstable plaque properties and the injury of nerve function.

    Full Text Available Background. Comprehensive analysis of proteome differentially expressed in response to surgery or drug treatment is useful to understand biological responses to dispensed interventions. Here we investigated expression changes in sera of patients who suffered from calcific aortic stenosis (CAS, before and after surgery for aortic valve replacement. Materials and Methods. Sera obtained before and after surgery with depletion of highly abundant proteins were analyzed with iTRAQ labeling followed by nanoLC-MALDI-TOF/TOF-MS/MS. Results. Fifty-one proteins shared in five patients were identified with differential levels in postsurgical and presurgical sera. Finally, 16 proteins that show statistically significant levels in patients’ sera compared with those in control sera (P<0.05 were identified. Most of the identified proteins were positive acute-phase proteins. Among three proteins other than acute-phase proteins, we confirmed increased levels of antithrombin-III and zinc-α-2-glycoprotein in postsurgical sera by Western blot analysis using other CAS patients’ sera. Furthermore, antithrombin-III and zinc-α-2-glycoprotein were not found among proteins with differential levels in postsurgical and presurgical sera of patients with aortic aneurysms that we identified in a previous study. Conclusions. The results indicated that antithrombin-III and zinc-α-2-glycoprotein would become unique monitoring proteins for evaluating pathophysiological and biochemical processes occurring before and after surgery for CAS.

    Daratumumab is a fully human anti-CD38 IgG1-κ monoclonal antibody (mAb) currently being evaluated in several Phase 2 and 3 clinical studies for the treatment of multiple myeloma (MM). In this clinical case study we demonstrate that daratumumab can be detected as an individual monoclonal band in serum immunofixation electrophoresis (IFE). M-protein follow-up by IFE is part of the International Myeloma Working Group (IMWG) criteria to assess treatment response. Therefore, it is crucial that the daratumumab band is not confused with the endogenous M-protein of the patient during IFE interpretation. Moreover, a significant number of IgG-κ M-proteins co-migrate with daratumumab. Co-migration introduces a bias in the M-protein quantification since pharmacokinetic studies show that daratumumab peak plasma concentrations reach up to 1 g/L. More importantly, co-migration can mask clearance of the M-protein by IFE which is necessary for classification of complete response by IMWG criteria (negative serum IFE). For optimal M-protein monitoring the laboratory specialist needs to be informed when patients receive daratumumab, and it is essential that the laboratory specialist is aware that a slow migrating band in the γ-region in those patients may be derived from the daratumumab. A daratumumab specific IFE reflex assay (DIRA) has been developed and can be utilized to abrogate interference. The here described mAb interference is not limited to daratumumab, and as therapeutic antibodies gain approval and enter into common clinical practice, laboratory specialists will need additional processes to characterize IFE interference and distinguish endogenous M-protein from therapeutic antibodies.

    Serum CA-15.3 and CEA levels were longitudinally determined in 307 patients with breast carcinoma during postsurgical follow-up and/or therapy. Of 120 patients with no apparent disease, the specificity of marker levels fluctuating within the normal range (true-negative) was 98% for CA-15.3 alone (P = 0.004) and about 88% for CEA alone or for the tests combined. However, the false-negative levels in patients with progressive cancer reduced the predictive value of the tandem to around 76%, i.e. normal levels of both markers correctly predicted uneventful postsurgical course in only three fourths of the patients. Of 187 patients with active disease, the sensitivity of raised or increasing marker levels was around 70% for CA-15.3 alone or CEA alone, and 82% for the tests combined (P = 0.006). The 11% false-positive rate of CEA in patients with no apparent disease decreased the predictive value of a positive test from 98% for CA-15.3 alone (P = 0.006) to 91% for CEA alone or the tandem. Serum CA-15.3 or CEA paralleled the site of relapse: at least one marker was found elevated in 60% of patients with locoregional disease or with metastases to the lungs or bones exclusively, and in 90% of those with metastases to the lungs and bones or to the liver. A concurrent decrease of both marker levels reflected response to therapy while an increase of at least one marker level reflected treatment failure. It may be concluded that the marker tandem was better than either marker alone for follow-up aimed at detection of relapse, and that the tests were approximately 80% accurate for follow-up and/or monitoring therapy.

    Full Text Available The development of new growth hormone (GH agonists and growth hormone antagonists (GHAs requires animal models for pre-clinical testing. Ideally, the effects of treatment are monitored using the same pharmacodynamic marker that is later used in clinical practice. However, intact rodents are of limited value for this purpose because serum IGF-I, the most sensitive pharmacodynamic marker for the action of GH in humans, shows no response to treatment with recombinant human GH and there is little evidence for the effects of GHAs, except when administered at very high doses or when overexpressed. As an alternative, more suitable model, we explored pharmacodynamic markers of GH action in intact rabbits. We performed the first validation of an IGF-I assay for the analysis of rabbit serum and tested precision, sensitivity, linearity and recovery using an automated human IGF-I assay (IDS-iSYS. Furthermore, IGF-I was measured in rabbits of different strains, age groups and sexes, and we monitored IGF-I response to treatment with recombinant human GH or the GHA Pegvisomant. For a subset of samples, we used LC-MS/MS to measure IGF-I, and quantitative western ligand blot to analyze IGF-binding proteins (IGFBPs. Although recovery of recombinant rabbit IGF-I was only 50% in the human IGF-I assay, our results show that the sensitivity, precision (1.7–3.3% coefficient of variation and linearity (90.4–105.6% were excellent in rabbit samples. As expected, sex, age and genetic background were major determinants of IGF-I concentration in rabbits. IGF-I and IGFBP-2 levels increased after single and multiple injections of recombinant human GH (IGF-I: 286±22 versus 434±26 ng/ml; P<0.01 and were highly correlated (P<0.0001. Treatment with the GHA lowered IGF-I levels from the fourth injection onwards (P<0.01. In summary, we demonstrated that the IDS-iSYS IGF-I immunoassay can be used in rabbits. Similar to rodents, rabbits display variations in IGF-I depending on

    In this work, the adsorption of human serum albumin (HSA) on the bare multiwall carbon nanotube (MWNT) was investigated by a new electrochemical method, termed as zero current potentiometry. For this, a MWNT strip was prepared by directly adhering MWNTs on the transparent adhesive tape surface. Moreover, when HSA adsorbed onto MWNT at the MWNT/solution interface, an interface potential Ψ yielded. The interface potential Ψ as the zero current potential Ezcp simply related to it was monitored by zero current potentiometry. The relationship between the zero current potential Ezcp, the HSA concentration and others was established in simple stoichiometric relation. Based on this, both the adsorption of HSA on MWNT and the HSA determination can be studied. For the HSA determination, the theoretic conclusion consisted with experimental results. The zero current potential Ezcp was proportional to the HSA concentration in the range of 2.8 × 10(-8) - 3.4 × 10(-7)M with the limit of detection 2 × 10(-8)M. The linear regression equation was Ezcp/V (vs, SCE) = (0.159 ± 0.01) + (0.358 ± 0.02) × 10(6)CHSA (µM). This determination was fast, high sensitive and good selective.

    Sequential serum samples from leprosy patients at various stages of antibacterial treatment were tested by an ELISA for antibodies to phenolic glycolipid I (PGL-I), a synthetic PGL-I analog (ND-BSA), and lipoarabinomannan (LAM) from Mycobacterium tuberculosis to determine if these antibodies could be useful in monitoring response to therapy. Among patients with positive initial anti-PGL-I IgM, a significant decrease in this antibody was seen over time (p less than 0.01), whether assayed by PGL-I or ND-BSA. The two antigens showed good agreement in the detection of decrease in anti-PGL-I IgM. The greatest decrease was seen in patients with a high initial anti-PGL-I IgM and a high bacterial index (BI). Patients with a declining BI were seen to have generally declining antibody levels to PGL-I and to LAM; in those patients with a fluctuating BI, antibody levels were less predictable. We conclude that antibodies to PGL-I and LAM can be useful in following response to therapy in leprosy patients and that either the native PGL-I or ND-BSA can serve as antigen for the ELISA.

    The objective of this study is to assess serum IL8 and the potential activity of circulating neutrophils on relative messenger RNA (mRNA) levels and their relationship with disease activity in clinically amyopathic dermatomyositis (CADM) associated with interstitial lung disease (ILD). We studied 18 CADM patients and compared them with 18 classic dermatomyositis (DM) patients and 18 healthy control subjects. Serum IL8 level and mRNA expressions of neutrophils (chemokine (C-X-C motif) receptor 1 (CXCR1), cluster of differentiation molecule 11b (CD11b), cluster of differentiation 64 (CD64), myeloid cell leukemia 1 (MCL1), interleukin-18 (IL18)) were detected. The overproduction of serum IL8 level was most significant in the CADM group with active period. The mRNA expressions of CD11b, IL18, and MCL1 were greatly increased in the neutrophils in patients with CADM compared with DM or healthy controls. Up-expressions of CD11b, IL18, and MCL1 were detected in the neutrophils in CADM patients of active period compared with remission period. A positive correlation was found between CD11b mRNA level and high-resolution computed tomography (HRCT) score, in CADM associated with ILD. Serum IL8 level and mRNA levels of CD11b, MCL1, and IL18 in circulating neutrophils are related with the disease activity of CADM-ILD. The mRNA level of CD11b is positively correlated with HRCT score in CADM-ILD.

    Patients with relapsed and refractory Hodgkin lymphoma (HL) may experience long-term survival after allogeneic stem cell transplantation (alloSCT), but disease recurrence represents the main cause of treatment failure. Positron-emission tomography (PET)-positive patients after alloSCT have a dismal outcome. Serum thymus and activation-regulated chemokine (TARC) is produced by Reed-Sternberg cells and may be a marker of disease. Our study aimed at assessing whether TARC levels after alloSCT correlated with disease status and whether TARC monitoring could increase the ability to predict relapse. Twenty-four patients were evaluated in a prospective observational study. TARC serum level and PET were assessed before and after alloSCT during the follow-up (median, 30 months; range, 2 to 54). Before alloSCT, the median TARC level was 721 pg/mL (range, 209 to 1332) in PET-negative patients and 2542 pg/mL (range, 94 to 13,870) in PET-positive patients. After alloSCT, TARC was 620 pg/mL (range, 12 to 4333) in persistently PET-negative patients compared with 22,397 pg/mL (range, 602 to 106,578) in PET-positive patients (P disease status and its monitoring may be able to predict PET positivity after alloSCT, thus potentially allowing an early immune manipulation.

    We proposed a simple analytical procedure for measurement of serum advanced glycosylation end products (AGEs) based on simultaneous detection of low-molecular-mass peptides and AGEs with a flow system and two detectors connected on-line: spectrophotometric for peptides (lambda = 280 nm) and spectrofluorometric for AGEs (lambda ex = 247 nm, lambda em = 440 nm). Sample pretreatment was carried out in microcentrifuge tubes: Serum (20 microL) was deproteinized with trichloroacetic acid (480 microL, 0.15 mol/L) and lipids were extracted with chloroform (100 microL). Twenty microliters of the filtered aqueous layer was injected to the flow system and the relation between fluorescence and absorption signals was measured. A peptide-derived AGE calibrator was used for calibration. Within-day and between-day CVs were 6.7% and 9.1%, respectively, at an AGE concentration corresponding approximately to that in healthy individuals. Mean results (+/-SD) in 10 healthy individuals were 10.1% +/- 1.0%, in 21 patients with diabetes without complications 18.0% +/- 6.2%, in 25 patients with complications 24.1% +/- 15.4%, and in 12 diabetic patients in end-stage renal disease 92% +/- 30%. Comparison with an ELISA procedure (x, in arbitrary units/L) yields a regression equation y = 0.713x + 1.24 (Sy [symbol: see text] x = 6777, r = 0.8477, n = 41).

    The main objective of this study was to assess the diagnostic performance of a set of three Mucorales quantitative PCR assays in a retrospective multicentre study. Mucormycosis cases were recorded thanks to the French prospective surveillance programme (RESSIF network). The day of sampling of the first histological or mycological positive specimen was defined as day 0 (D0). Detection of circulating DNA was performed on frozen serum samples collected from D-30 to D30, using quantitative PCR assays targeting Rhizomucor, Lichtheimia, Mucor/Rhizopus. Forty-four patients diagnosed with probable (n = 19) or proven (n = 25) mucormycosis were included. Thirty-six of the 44 patients (81%) had at least one PCR-positive serum. The first PCR-positive sample was observed 9 days (range 0-28 days) before diagnosis was made using mycological criteria and at least 2 days (range 0-24 days) before imaging. The identifications provided with the quantitative PCR assays were all concordant with culture and/or PCR-based identification of the causal species. Survival rate at D84 was significantly higher for patients with an initially positive PCR that became negative after treatment initiation than for patients whose PCR remained positive (48% and 4%, respectively; p mucormycosis diagnosis when other mycological arguments were present but could also anticipate this diagnosis. Quantification of DNA loads may also be a useful adjunct to treatment monitoring.

    Full Text Available Atopic dermatitis (AD is an inflammatory skin disease in which pathogenesis chemokines are partially involved. The aim of the paper was to assess the serum level of CXCL-9, CXCL-10, CXCL-11, CXCL-12, CCL-17, CCL-20, CCL-21, CCL-22, CCL-27, and IL-18 chosen in AD patients by ELISA assay. Forty patients (mean age 11.4 years old with AD and 50 healthy controls were enrolled into the study. The patients and controls were divided into two age categories: under 10 years old (Group 1 and Control 1 and over 10 years old (Group 2 and Control 2. Significantly lower serum concentration of CXCL-9, CXCL-10, CCL-17, and IL-18 and higher concentration of CXCL-12 and CCL-27 were found in Group 1 when compared to Control 1. In Group 2 serum concentration of CXCL-12, CCL-17, CCL-22 was higher than in Control 2. The obtained results indicate the imbalance in chemokine serum levels in AD what suggests their role in the disease pathogenesis.

    To explore the clinical significance of serum levels of IL-6/10/18 in sepsis. Sixty-six patients with sepsis were selected to be the case group. Additionally, 42 healthy adults were selected to be the control group. ELISA was used to measure the serum levels of IL-6/10/18, and ROC was utilized to evaluate the diagnostic values of IL-6/10/18 in sepsis. The heart rate, respiratory rate, WBC count and APACHE II score in the sepsis group were significantly higher than those in the control group, and these indexes were increased in turn in the mild sepsis group, severe sepsis group, and septic shock group (all P sepsis patients were significantly higher than those in the control group, and both of the levels were increased in turn in the mild sepsis group, severe sepsis group, and septic shock group (both P 0.05). The cut-off points of IL-6 and IL-18 were 109.19 pg/ml (sensitivity: 94.4%; specificity: 83.3%) and 116.01 pg/ml (sensitivity: 77.8%; specificity: 83.3%), respectively. Serum IL-6 levels were positively correlated with the APACHE II score and heart rate (both P sepsis patients. Additionally, IL-6 has a greater sensitivity than IL-18. Serum IL-6 levels were positively correlated with the APACHE II score and heart rate, indicating that IL-6 could be used as a potential biomarker for sepsis. © 2016 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Despite the use of anti-platelet agents such as acetylsalicylic acid (ASA and clopidogrel in coronary heart disease, some patients continue to suffer from atherothrombosis. This has stimulated development of platelet function assays to monitor treatment effects. However, it is still not recommended to change treatment based on results from platelet function assays. This study aimed to evaluate the capacity of a static platelet adhesion assay to detect platelet inhibiting effects of ASA and clopidogrel. The adhesion assay measures several aspects of platelet adhesion simultaneously, which increases the probability of finding conditions sensitive for anti-platelet treatment. Methods With a randomised cross-over design we evaluated the anti-platelet effects of ASA combined with clopidogrel as well as monotherapy with either drug alone in 29 patients with a recent acute coronary syndrome. Also, 29 matched healthy controls were included to evaluate intra-individual variability over time. Platelet function was measured by flow cytometry, serum thromboxane B2 (TXB2-levels and by static platelet adhesion to different protein surfaces. The results were subjected to Principal Component Analysis followed by ANOVA, t-tests and linear regression analysis. Results The majority of platelet adhesion measures were reproducible in controls over time denoting that the assay can monitor platelet activity. Adenosine 5'-diphosphate (ADP-induced platelet adhesion decreased significantly upon treatment with clopidogrel compared to ASA. Flow cytometric measurements showed the same pattern (r2 = 0.49. In opposite, TXB2-levels decreased with ASA compared to clopidogrel. Serum TXB2 and ADP-induced platelet activation could both be regarded as direct measures of the pharmacodynamic effects of ASA and clopidogrel respectively. Indirect pharmacodynamic measures such as adhesion to albumin induced by various soluble activators as well as SFLLRN

    Full Text Available Background: Mesenchymal stem cells are capable of self-renewal and multi-lineage differentiation. They are used extensively to treat several diseases. Traditionally, mesenchymal stem cells are cultured in serum-containing media, typically supplemented with fetal bovine serum (FBS. However, the variability of FBS is likely to skew experimental results. Although serum-free media used to expand mesenchymal stem cells has facilitated remarkable achievements, immunomodulation of these cells in under serum-free conditions is poorly understood. We hypothesized that mesenchymal stem cells expanded in serum-free media will retain powerful immunoregulatory functions in vitro and in vivo. Design and Methods: Immunosuppressive activity and the immunomodulatory cytokines produced by mesenchymal stem cells in serum-free media were characterized in vitro. Immunomodulation by serum-free mesenchymal stem cell expansion in monocrotaline-induced pulmonary hypertension was explored in vivo. Results: Similar to cells in serum-containing media, mesenchymal stem cells expanded in serum-free media inhibited proliferation and apoptosis of CD4+T cells. They also exhibited strong immunosuppressive activities and secreted high levels of immunomodulatory cytokines such as PGE2, IDO1, COX2, IL-6, and IL-1β, but not HGF. On the other hand, growth of mesenchymal stem cells in serum-free media attenuated pulmonary vascular remodeling and inhibited mRNA expression of proinflammatory cytokines TNF-α, IFN-γ, IL-6, IL-1β, and IL-18. Conclusions: Mesenchymal stem cells in serum-free media maintained powerful immunomodulatory function in vitro and in vivo; serum-free media may replace serum-containing media for basic research and clinical applications.

    Risperidone is an atypical antipsychotic commonly used for treatment of schizophrenia and other psychotic disorders. Although therapeutic drug monitoring is not routine for any of the atypical antipsychotics, serum antipsychotic concentrations are measured routinely to assess treatment nonadherence. In humans, risperidone is metabolized by cytochrome P450 2D6 to 9-hydroxyrisperidone; together these constitute the active moiety. Dose-proportional increases in serum concentrations have not been reported for the parent drug, but have been reported for 9-hydroxyrisperidone and the active moiety (i.e., the combined concentrations of risperidone and 9-hydroxyrisperidone). We describe a 34-year-old Caucasian man of Sicilian descent with a history of schizophrenia, disorganized type. He was suspected to be noncompliant with his risperidone therapy. Initially, active moiety risperidone concentrations increased linearly with prescribed dosage increases. However, with continued increases, active moiety concentrations adjusted downward and remained 17-36% below anticipated levels. We propose a method for estimating target active moiety concentrations of risperidone based on dosage-a method that may be used to guide clinicians in assessing nonadherence to risperidone treatment.

All patients were given symptomatic and conventional treatment according to the specific circumstances, patients in the control group were treated with 10 mg montelukast with orally once per night on the basis of conventional treatment, and observation group patients was given 18 μg tiotropium bromide inhalation once per night on the basis of control group. All the patients were treated for 4 weeks, the blood rheology indexes, pulmonary function indexes and serum cytokines were measured and compared between the two groups before and after treatment.Results: Before treatment, there was no significant difference in blood rheology index of whole blood viscosity (high shear viscosity, shear viscosity, low shear viscosity), plasma viscosity, hematocrit and fibrinogen (P>0.05); After treatment, the blood rheology indexes of the two groups were significantly decreased compared with that in the same group before treatment (P0.05). After treatment, the indexes of pulmonary function in the two groups were significantly higher than that in the same group before treatment (P0.05); After treatment, the two groups’ serum IL-10, APN levels were significantly increased, IL-18 levels were significantly reduced (P<0.05). Meanwhile, serum IL-10, APN levels in Observation group were significantly increased, IL-18 levels were significantly lower than that in control group (P<0.05).Conclusions: The comibinition of tiotropium bromide with montelukas not only can improve the indexes of blood rheology in patients with COPD, and can significantly control the level of serum cytokines and control symptoms, improve lung function, so it is worth further clinical

  6. Piezoelectric microcantilever serum protein detector

    Science.gov (United States)

    Capobianco, Joseph A.

    The development of a serum protein detector will provide opportunities for better screening of at-risk cancer patients, tighter surveillance of disease recurrence and better monitoring of treatment. An integrated system that can process clinical samples for a number of different types of biomarkers would be a useful tool in the early detection of cancer. Also, screening biomarkers such as antibodies in serum would provide clinicians with information regarding the patient's response to treatment. Therefore, the goal of this study is to develop a sensor which can be used for rapid, all-electrical, real-time, label-fee, in-situ, specific quantification of cancer markers, e.g., human epidermal receptor 2 (Her2) or antibodies, in serum. To achieve this end, piezoelectric microcantilever sensors (PEMS) were constructed using an 8 mum thick lead magnesium niobate-lead titanate (PMN-PT) freestanding film as the piezoelectric layer. The desired limit of detection is on the order of pg/mL. In order to achieve this goal the higher frequency lateral extension modes were used. Also, as the driving and sensing of the PEMS is electrical, the PEMS must be insulated in a manner that allows it to function in aqueous solutions. The insulation layer must also be compatible with standardized bioconjugation techniques. Finally, detection of both cancer antigens and antibodies in serum was carried out, and the results were compared to a standard commercialized protocol. PEMS have demonstrated the capability of detecting Her2 at a concentration of 5 pg/mL in diluted human serum (1:40) in less than 1 hour. The approach can be easily translated into the clinical setting because the sensitivity is more than sufficient for monitoring prognosis of breast cancer patients. In addition to Her2 detection, antibodies in serum were assayed in order to demonstrate the feasibility of monitoring the immune response for antibody-dependent cellular cytotoxicity (ADCC) in patients on antibody therapies

    Background Serum ferritin was discovered in the 1930’s, and was developed as a clinical test in the 1970’s. Many diseases are associated with iron overload or iron deficiency. Serum ferritin is widely used in diagnosing and monitoring these diseases. Scope of Review In this chapter, we discuss the role of serum ferritin in physiological and pathological processes and its use as a clinical tool. Major Conclusions Although many aspects of the fundamental biology of serum ferritin remain surprisingly unclear, a growing number of roles have been attributed to extracellular ferritin, including newly described roles in iron delivery, angiogenesis, inflammation, immunity, signaling and cancer. General Significance Serum ferritin remains a clinically useful tool. Further studies on the biology of this protein may provide new biological insights. PMID:20304033

    Babesia rossi infection causes a severe inflammatory response in the dog, which is the result of the balance between pro- and anti-inflammatory cytokine secretion. The aim of this study was to determine whether changes in cytokine concentrations were present in dogs with babesiosis and whether it was associated with disease outcome. Ninety-seven dogs naturally infected with B. rossi were studied and fifteen healthy dogs were included as controls. Diagnosis of babesiosis was confirmed by polymerase chain reaction and reverse line blot. Blood samples were collected from the jugular vein at admission, prior to any treatment. Cytokine concentrations were assessed using a canine-specific multiplex assay on an automated analyser. Serum concentrations of interleukin (IL)-2, IL-6, IL-8, IL-10, IL-18, granulocyte-macrophage colony stimulating factor (GM-CSF) and monocyte chemotactic protein-1 (MCP-1) were measured. Twelve of the Babesia-infected dogs died (12%) and 85 survived (88%). Babesia-infected dogs were also divided into those that presented within 48 hours from displaying clinical signs, and those that presented more than 48 hours after displaying clinical signs. Cytokine concentrations were compared between the different groups using the Mann-Whitney U test. IL-10 and MCP-1 concentrations were significantly elevated for the Babesia-infected dogs compared to the healthy controls. In contrast, the IL-8 concentration was significantly decreased in the Babesia-infected dogs compared to the controls. Concentrations of IL-6 and MCP-1 were significantly increased in the non-survivors compared to the survivors. Concentrations for IL-2, IL-6, IL-18 and GM-CSF were significantly higher in those cases that presented during the more acute stage of the disease. These findings suggest that a mixed cytokine response is present in dogs with babesiosis caused by B. rossi, and that an excessive pro-inflammatory response may result in a poor outcome.

    Rheumatoid arthritis (RA) and periodontitis are common chronic inflammatory conditions and share many pathologic features. A similar profile of cytokines is involved in the pathogenesis of the two diseases. The relationship between the disease activity of RA and the periodontal condition remains unclear. This study examines whether the disease activity of RA affects serum cytokine and periodontal profiles. The study subjects consisted of 84 Japanese adults with RA and 22 race-matched control individuals. After periodontal and rheumatologic examination, the disease activity of RA was determined with the Disease Activity Score including 28 joints using C-reactive protein (DAS28-CRP). Serum levels of cytokines including interleukin (IL)-1beta, IL-6, IL-12, IL-12 p40, IL-18, and tumor necrosis factor-alpha (TNF-alpha) were determined by an enzyme-linked immunosorbent assay. High-sensitive CRP was also measured with a latex particle-enhanced nephelometric method. Of 84 patients with RA, 28 and 56 patients exhibited low and moderate to high disease activity, respectively. Serum levels of IL-6, TNF-alpha, and CRP were significantly different between the two groups (P <0.05). Additionally, a significant correlation was observed between DAS28-CRP and percentage of sites with bleeding on probing (BOP) (P = 0.008) and between serum TNF-alpha levels and percentage of sites with BOP (P = 0.01) in 56 patients with RA with moderate to high activity. These results suggest that the disease activity of RA correlated with serum levels of IL-6, TNF-alpha, and CRP, and it might influence BOP in the patients with moderate to high disease activity.

    1997-07-18

    A method for the quantification of ketoprofen, a new non-prescription non-steroidal anti-inflammatory drug, in serum, by capillary zone electrophoresis for therapeutic monitoring and emergency toxicology is described. Serum is deproteinized with acetonitrile in the presence of an internal standard, to remove serum proteins and to induce sample stacking. The migration time was about 10 min. The assay was linear between 1-10 mg/l without any interferences. The method compared well to an HPLC assay. The HPLC afforded a better detection limit, but the CE was less expensive to operate. This method demonstrates that capillary electrophoresis is a simple and effective method for determination of ketoprofen as well as other drugs in human serum at levels close to 1 mg/l.

    To investigate the impact of inpatient detoxification treatment on psychiatric symptoms of chronic cannabis addicts and to analyze the influence of serum cannabinoid levels on the severity of these symptoms. Thirty five treatment-seeking, not active co-morbid chronic cannabis dependents (ICD-10) were studied on admission and on abstinence days 8 and 16, using several observational and self-report scales, such as Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Young Mania Rating Scale (YMRS) and Brief Psychiatric Rating Scale (BPRS), and the Symptom Checklist-90-Revised (SCL-90-R). Simultaneously obtained serum was analyzed with regard to levels of delta-9-tetrahydrocannabinol (THC) and its main metabolites 11-hydroxy-delta-9-tetrahydrocannabinol (THC-OH) and 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH). At admission, nearly 90% of the patients were not, or only mildly, affected by depression, anxiety or manic symptoms. In contrast, patients' self-description indicated a strong psychiatric burden in approximately 60% of the cases. All patients improved significantly within 16 days of the treatment. Effect sizes ranged from 0.7 to 1.4. (Cohen's d) for the respective scales. Serum THC-levels were positively associated with impairment of cognition in HAMA and motor retardation in BPRS. All other test results were not significantly related to the serum levels of the measured cannabinoids. Effects of the cannabis withdrawal syndrome and executive dysfunctions might explain the discrepancy between the observer ratings and self-reported psychiatric burden. Inpatient cannabis detoxification treatment significantly improved psychiatric symptoms. Serum THC-levels were not associated with affective symptoms and anxiety but predicted cognitive impairment and motor retardation. Copyright © 2015. Published by Elsevier Ireland Ltd.

  4. Serum Antibody Repertoire Profiling Using In Silico Antigen Screen.

    Full Text Available Serum antibodies are valuable source of information on the health state of an organism. The profiles of serum antibody reactivity can be generated by using a high throughput sequencing of peptide-coding DNA from combinatorial random peptide phage display libraries selected for binding to serum antibodies. Here we demonstrate that the targets of immune response, which are recognized by serum antibodies directed against sequential epitopes, can be identified using the serum antibody repertoire profiles generated by high throughput sequencing. We developed an algorithm to filter the results of the protein database BLAST search for selected peptides to distinguish real antigens recognized by serum antibodies from irrelevant proteins retrieved randomly. When we used this algorithm to analyze serum antibodies from mice immunized with human protein, we were able to identify the protein used for immunizations among the top candidate antigens. When we analyzed human serum sample from the metastatic melanoma patient, the recombinant protein, corresponding to the top candidate from the list generated using the algorithm, was recognized by antibodies from metastatic melanoma serum on the western blot, thus confirming that the method can identify autoantigens recognized by serum antibodies. We demonstrated also that our unbiased method of looking at the repertoire of serum antibodies reveals quantitative information on the epitope composition of the targets of immune response. A method for deciphering information contained in the serum antibody repertoire profiles may help to identify autoantibodies that can be used for diagnosing and monitoring autoimmune diseases or malignancies.

    Full Text Available Abstract Objective In this study, we determined circulating levels of C-reactive protein, several cytokines, chemokines, adhesion molecules and angiogenic factors along with those of leptin in healthy non-pregnant and pregnant women and preeclamptic patients, and investigated whether serum leptin levels were related to the clinical characteristics and measured laboratory parameters of the study participants. Methods Sixty preeclamptic patients, 60 healthy pregnant women and 59 healthy non-pregnant women were involved in this case-control study. Levels of leptin and transforming growth factor (TGF-beta1 in maternal sera were assessed by ELISA. Serum levels of interleukin (IL-1beta, IL-1 receptor antagonist (IL-1ra, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p40, IL-12p70, IL-18, interferon (IFN-gamma, tumor necrosis factor (TNF-alpha, interferon-gamma-inducible protein (IP-10, monocyte chemotactic protein (MCP-1, intercellular adhesion molecule (ICAM-1 and vascular cell adhesion molecule (VCAM-1 were determined by multiplex suspension array. Serum C-reactive protein (CRP concentrations were measured by an autoanalyzer. Serum total soluble fms-like tyrosine kinase-1 (sFlt-1 and biologically active placental growth factor (PlGF levels were determined by electrochemiluminescence immunoassay. For statistical analyses, non-parametric methods were applied. Results There were significant differences in most of the measured laboratory parameters among the three study groups except for serum IL-1beta and TGF-beta1 levels. Serum leptin levels were significantly higher in preeclamptic patients and healthy pregnant women than in healthy non-pregnant women. Additionally, preeclamptic patients had significantly higher leptin levels as compared to healthy pregnant women. Serum leptin levels were independently associated with BMI in healthy non-pregnant women. In healthy pregnant women, both BMI and serum CRP concentrations showed significant positive linear

    The unbound fraction of many drugs appears to be the therapeutically active component. However, the major problem encountered in following unbound serum gold (UBSG) concentration during chrysotherapy has been the ability to quantitate such a small quantity of gold reliably without matrix interference. The methodology detailed here overcomes these difficulties and provides an effective means of monitoring the UBSG fraction during chrysotherapy. We have observed that the unbound fraction of gold dissipates quickly after gold sodium thiomalate administration and constitutes less than 2% of the total serum gold concentration.

    Two studies comparing sewage-isolated and laboratory stock viruses were conducted to determine if alternative forms of serum or serum extenders could be used in place of fetal bovine serum without a significant loss of viral titer. In the first study, BGM cells were grown in standard MEM-L15 medium which was supplemented with Nuserum, Sigma serum replacement (CPSR-1), HyClone defined iron supplemented calf bovine serum, fetal bovine serum (FBS) or FBS supplemented with either SerXtend or Mito serum extenders. Comparison of virus titers showed that CPSR-1 gave the best overall results and was comparable to FBS. Of the serum extenders, only SerXtend improved virus recovery from sewage samples. In the second study, all sera were tested with and without SerXtend. In these experiments, SerXtend enhanced virus sensitivity of the BGM cell line grown in the HyClone serum but reduced the sensitivity of those cultured in Sigma serum. In both series, the growth of BGM cells was monitored for 12 weeks and all test products were shown to support long-term cell growth.

    Objective To evaluate the validity of a serum carbohydrate antigen 19-9(CA19-9) determination in the diagnosis of extrahepatic cholangiocarcinoma(EHCC). Methods Serum CA19-9 concentration and serum carcinoembryonic antigen(CEA) concentration were prospectively measured by an immunoradiometric assay without knowledge of the clinical diagnosis in patients with EHCC (n=51), benign biliary diseases (n=42), and healthy individuals (n=15). Using a receiver operating characteristic (ROC) curve define a new strategy for interpreting CA19-9 and CEA in EHCC. Results The sensitivity of CA19-9 and CEA in diagnosing EHCC were 86.3% (44/51) and 25.5%(13/51), respectively. When compared with the benign biliary diseases group, the true negative rates of serum CA19-9 and serum CEA were 85.7% (36/42) and 95.2%(40/42), respectively. The false positive rates of serum CA19-9 and serum CEA were 14.3 %( 6/42) and 4.8 %( 2/42), whereas the accuracy of serum CA19-9 and serum CEA were 57.0%(53/93) and 86.0%(80/93), respectively. Serum CA19-9 concentration and serum CEA concentration were significantly elevated (P0.05), respectively. In 22 patients undergoing curative resection of EHCC, the mean serum CA19-9 concentration decreased from preoperative level of (456.6±120.4) kU·L-1 to postoperative level (62.8±17.3) kU·L-1(P<0.001). The outcomes showed that serum CA19-9 had greater diagnosis performances than serum CEA. Conclusion Serum CA19-9 is an effective tumor marker in diagnosing of cholangiocarcinoma, deciding whether the tumor has been radically resected and monitoring effect of treatment

    As many as 2247 patients with different clinical forms of diphtheria were examined. Antidiphtheric serum (ADS) was administered in 1556 children, the dosage being determined by condition of the patient. Serum sickness developed at day 7 to 9 in 24 (1.5%); 10 patients were found to run a mild course, 14--moderately severe. 6 patients had allergic reactions: 3--to antibiotic (penicillin), urticaria type, 1--to pertussoid-tetanic anatoxin, 2 had pollinosis-type reaction. Thus, serum sickness has practical value, which fact requires a detailed allergic history together with skin tests to be performed before the administration of ADS.

    Although there was an important improvement in graft and patient survival the last 10 years, graft rejection continues to be a major barrier to the success of renal transplantation. Identification of a laboratory test that could help to diagnose graft rejection would facilitate the management of renal transplanted patients. PURPOSE--To evaluate the utility of monitoring serum beta 2M in recently transplanted patients. METHODS--We daily determined serum beta 2M levels in 20 receptors of renal grafts (10 from living related and 10 from cadaveric donors) and compared them to their clinical and laboratory evolution. RESULTS--Eight patients who presented immediate good renal function following grafting and did not have rejection had a mean serum beta 2M of 3.7 mg/L on the 4th day post transplant. The sensitivity of the test for the diagnosis of acute rejection was 87.5%, but the specificity was only 46%. Patients who presented acute tubular necrosis (ATN) without rejection had a progressive decrease in their serum levels of beta 2M, while their serum creatinine changed as they were dialyzed. In contrast, patients with ATN and concomitance of acute rejection or CSA nephrotoxicity presented elevated beta 2M and creatinine serum levels. CONCLUSION--Daily monitoring of serum beta 2M does not improve the ability to diagnose acute rejection in patients with good renal function. However, serum beta 2M levels seemed to be useful in diagnosing acute rejection or CSA nephrotoxicity in patients with ATN.

    Abstract The precise cytokine networks in the serum of individuals with familial Mediterranean fever (FMF) that are associated with its pathogenesis have been unknown. Here, we attempted to identify specific biomarkers to diagnose or assess disease activity in FMF patients. We measured serum levels of 45 cytokines in 75 FMF patients and 40 age-matched controls by multisuspension cytokine array. FMF in “attack” or “remission” was classified by Japan College of Rheumatology-certified rheumatologists according to the Tel Hashomer criteria. Cytokines were ranked by their importance by a multivariate classification algorithm. We performed a logistic regression analysis to determine specific biomarkers for discriminating FMF patients in attack. To identify specific molecular networks, we performed a cluster analysis of each cytokine. Twenty-nine of the 45 cytokines were available for further analyses. Eight cytokines’ serum levels were significantly elevated in the FMF attack versus healthy control group. Nine cytokines were increased in FMF attack compared to FMF remission. Multivariate classification algorithms followed by a logistic regression analysis revealed that the combined measurement of IL-6, IL-18, and IL-17 distinguished FMF patients in attack from the controls with the highest accuracy (sensitivity 89.2%, specificity 100%, and accuracy 95.5%). Among the FMF patients, the combined measurement of IL-6, G-CSF, IL-10, and IL-12p40 discriminated febrile attack periods from remission periods with the highest accuracy (sensitivity 75.0%, specificity 87.9%, and accuracy 84.0%). Our data identified combinational diagnostic biomarkers in FMF patients based on the measurement of multiple cytokines. These findings help to improve the diagnostic performance of FMF in daily practice and extend our understanding of the activation of the inflammasome leading to enhanced cytokine networks.

    Full Text Available Abstract Background The applications of proteomic strategies to ovine medicine remain limited. The definition of serum proteome may be a good tool to identify useful protein biomarkers for recognising sub-clinical conditions and overt disease in sheep. Findings from bovine species are often directly translated for use in ovine medicine. In order to characterize normal protein patterns and improve knowledge of molecular species-specific characteristics, we generated a two-dimensional reference map of sheep serum. The possible application of this approach was tested by analysing serum protein patterns in ewes with mild broncho-pulmonary disease, which is very common in sheep and in the peripartum period which is a stressful time, with a high incidence of infectious and parasitic diseases. Results This study generated the first reference 2-DE maps of sheep serum. Overall, 250 protein spots were analyzed, and 138 identified. Compared with healthy sheep, serum protein profiles of animals with rhino-tracheo-bronchitis showed a significant decrease in protein spots identified as transthyretin, apolipoprotein A1 and a significant increase in spots identified as haptoglobin, endopin 1b and alpha1B glycoprotein. In the peripartum period, haptoglobin, alpha-1-acid glycoprotein, apolipoprotein A1 levels rose, while transthyretin content dropped. Conclusions This study describes applications of proteomics in putative biomarker discovery for early diagnosis as well as for monitoring the physiological and metabolic situations critical for ovine welfare.

    Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

    The relationship between blood phenylalanine concentrations and serum and erythrocyte biopterin and neopterin concentrations was investigated in 20 phenylketonuric patients with different dietary compliance. At serum phenylalanine concentrations ranging from 43 to 1004 mumol/l, a good correlation was found with serum biopterin (r = 0.76, P < 0.001) and with red blood cell biopterin (r = 0.62, P < 0.001). A similar correlation was found between serum neopterin and phenylalanine (r = 0.60, P < 0.001). The correlation between red blood cell neopterin and serum phenylalanine was less evident, however (r = 0.47, P < 0.005). After oral loading with phenylalanine (100 mg/kg body weight), serum and red blood cell biopterin concentrations increased in patients with classical phenylketonuria as well as in one patient with dihydropteridine reductase deficiency in response to the induced acute hyperphenylalaninemia. One patient suffering from 6-pyruvoyl tetrahydropterin synthase deficiency was loaded orally with tetrahydrobiopterin (20 mg/kg body weight). The kinetics of administered cofactor confirmed its rapid absorption, with early increase of serum concentrations followed by its transport into the red blood cells. The half-life of biopterin was approximately 7 h in serum and 15 h in red blood cells. Because both values are less than the half-life of phenylalanine (20-30 h) in serum, biopterin measurement offers no advantage in monitoring dietary control in hyperphenylalaninemic patients.

  7. Antibacterial activities of serum from the Komodo Dragon (Varanus komodoensis

    2013-07-01

    Full Text Available Komodo dragons (Varanus komodoensis are able to feed on large prey items by injecting a dose of toxic bacteria with their bite that, over time, kills the prey by systemic infection. Dragons also suffer bites from other members of their own species during territorial disputes and feeding frenzies. However, they do not suffer the same fate as their prey, suggesting that they have developed a strong immunity to bacterial infections. This study was undertaken to determine the antibacterial activities of serum from the Komodo dragon. Bacterial cultures were treated with different volumes serum from Varanus komodoensis and the growth was monitored by optical density at 430 nm. In addition, the serum was treated with protease, chelators of divalent metal ions, or with mild heat to determine the mechanism of antibacterial activities. Treatment of bacterial cultures with serum from Komodo dragons (Varanus komodoensis resulted in a volume-dependent decrease in bacterial growth. Cultures of Escherichia coli, Staphylococcus aureus, and Klebsiella oxytoca exhibited moderate-strong growth inhibition by V. komodoensis serum, while cultures of Streptococcus epidermitis, Salmonella typhimurium, Providencia stuartii, and Shigella flexneri were nearly completely obliterated for 24 h by only 10% (v/v serum. The antibacterial activity of V. komodensis serum occurred very rapidly, as 18% of E. coli growth was inhibited by a five min exposure to serum. Furthermore, 10- and 20-min incubations of E. coli with serum from V. komodoensis resulted in 43 and 68% inhibition of bacterial growth, respectively. The bactericidal capacity of the serum against E. coli was 2,075,000 bacteria/μL serum, and was inhibited by mild heat treatment, pronase, EDTA, and phosphate, indicating that the anti-bacterial action is most probably due to the presence of a potent serum complement protein system.

    Heart failure (HF) affects around 500,000 people in the UK. HF medications are frequently underprescribed and B-type natriuretic peptide (BNP)-guided therapy may help to optimise treatment. To evaluate the clinical effectiveness and cost-effectiveness of BNP-guided therapy compared with symptom-guided therapy in HF patients. Systematic review, cohort study and cost-effectiveness model. A literature review and usual care in the NHS. (a) HF patients in randomised controlled trials (RCTs) of BNP-guided therapy; and (b) patients having usual care for HF in the NHS. Systematic review: BNP-guided therapy or symptom-guided therapy in primary or secondary care. Cohort study: BNP monitored (≥ 6 months' follow-up and three or more BNP tests and two or more tests per year), BNP tested (≥ 1 tests but not BNP monitored) or never tested. Cost-effectiveness model: BNP-guided therapy in specialist clinics. Mortality, hospital admission (all cause and HF related) and adverse events; and quality-adjusted life-years (QALYs) for the cost-effectiveness model. Systematic review: Individual participant or aggregate data from eligible RCTs. Cohort study: The Clinical Practice Research Datalink, Hospital Episode Statistics and National Heart Failure Audit (NHFA). A systematic literature search (five databases, trial registries, grey literature and reference lists of publications) for published and unpublished RCTs. Five RCTs contributed individual participant data (IPD) and eight RCTs contributed aggregate data (1536 participants were randomised to BNP-guided therapy and 1538 participants were randomised to symptom-guided therapy). For all-cause mortality, the hazard ratio (HR) for BNP-guided therapy was 0.87 [95% confidence interval (CI) 0.73 to 1.04]. Patients who were aged cost-effectiveness model, in patients aged costs (£64,777 vs. £58,139). BNP-guided therapy is cost-effective at a threshold of £20,000 per QALY. The limitations of the trial were a lack of IPD for most RCTs

    Complement activity has only recently been characterized in raw bovine milk. However, the activity of this component of the innate immune system was found to diminish as milk was subjected to heat or partitioning during cream separation. Detection of complement in milk relies on a bactericidal assay. This assay exploits the specific growth susceptibility of Escherichia coli O111 to the presence of complement. Practical application of the assay was demonstrated when a reduction in complement activity was recorded in the case of pasteurized and reduced-fat milks. This presented an opportunity to improve the functionality of the bactericidal assay by incorporating bioluminescence capability into the target organism. Following some adaptation, the strain was transformed by correctly integrating the p16Slux plasmid. Growth properties of the transformed strain of E. coli O111 were unaffected by the modification. The efficacy of the strain adaptation was correlated using the LINEST function analysis [r=0.966; standard error of prediction (SEy)=0.957] bioluminescence with that of bactericidal assay total plate counts within the range of 7.5 to 9.2 log cfu/mL using a combination of raw and processed milk samples. Importantly, the transformed E. coli O111 p16Slux strain could be identified in milk and broth samples using bioluminescence measurement, thus enabling the bactericidal assay-viability test to be monitored in real time throughout incubation.

    OBJECTIVES: To evaluate synovial tissue and serum biomarkers of disease activity, therapeutic response and radiographic progression during biological therapy for rheumatoid arthritis (RA). METHODS: Patients with active RA entered a randomised study of anakinra 100 mg\\/day, administered as monotherapy or in combination with pegsunercept 800 microg\\/kg twice a week. Arthroscopic synovial tissue biopsies were obtained at baseline and two further time points. Following immunohistochemical staining, selected mediators of RA pathophysiology were quantified using digital image analysis. Selected mediators were also measured in the serum. RESULTS: Twenty-two patients were randomly assigned: 11 received monotherapy and 11 combination therapy. American College of Rheumatology 20, 50 and 70 response rates were 64%, 64% and 46% with combination therapy and 36%, 9% and 0% with monotherapy, respectively. In synovial tissue, T-cell infiltration, vascularity and transforming growth factor beta (TGFbeta) expression demonstrated significant utility as biomarkers of disease activity and therapeutic response. In serum, interleukin 6 (IL-6), matrix metalloproteinase (MMP) 1, MMP-3 and tissue inhibitor of metalloproteinase 1 (TIMP-1) were most useful in this regard. An early decrease in serum levels of TIMP-1 was predictive of the later therapeutic outcome. Pretreatment tissue levels of T-cell infiltration and the growth factors vascular endothelial growth factor\\/TGFbeta, and serum levels of IL-6, IL-8, MMP-1, TIMP-1, soluble tumour necrosis factor receptor types I and II and IL-18 correlated with radiographic progression. CONCLUSIONS: Synovial tissue analysis identified biomarkers of disease activity, therapeutic response and radiographic progression. Biomarker expression in tissue was independent of the levels measured in the serum.

    Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33) and compare them with children with leukemia without fever (n=33) and also with healthy children (n=24). The median serum endocan level in the first group (children with febrile neutropenia) was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (Pfebrile neutropenia and the healthy control group (P>0.05). Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

    Full Text Available Continuing improvements in analytical technology along with an increased interest in performing comprehensive, quantitative metabolic profiling, is leading to increased interest pressures within the metabolomics community to develop centralized metabolite reference resources for certain clinically important biofluids, such as cerebrospinal fluid, urine and blood. As part of an ongoing effort to systematically characterize the human metabolome through the Human Metabolome Project, we have undertaken the task of characterizing the human serum metabolome. In doing so, we have combined targeted and non-targeted NMR, GC-MS and LC-MS methods with computer-aided literature mining to identify and quantify a comprehensive, if not absolutely complete, set of metabolites commonly detected and quantified (with today's technology in the human serum metabolome. Our use of multiple metabolomics platforms and technologies allowed us to substantially enhance the level of metabolome coverage while critically assessing the relative strengths and weaknesses of these platforms or technologies.

    In this prospective study, serum hyaluronate (SH) was assayed using a radiometric method (Pharmacia) in 73 osteoarthritis patients and 39 controls. All assays were performed between 8 h 00 and 9 h 00 a.m. because SH levels exhibit circadian variations. SH levels were significantly higher in patients with osteoarthritis than in controls (92 +/- 66 micrograms/l and 39 +/- 21 micrograms/l, respectively, p = 0.0001). Among 50 patients with osteoarthritis, including 29 with knee involvement and 21 with hip involvement, SH levels were not correlated with morning stiffness, duration of symptoms, Lequesne's algofunctional index, erythrocyte sedimentation rate, C-reactive protein, severity of roentgenographic changes in the affected knee or hip, disease extension, or severity. The lack of any relationship between changes in SH levels and Lequesne's is index values in 25 patients or between SH levels and joint space narrowing evaluated retrospectively in 16 patients, as well as the prompt return to high SH levels after arthroplasty and synovectomy in 14 patients with hip joint osteoarthritis, suggest that this potential marker is not useful for monitoring osteoarthritis in a single joint.

    Psoriasis has been accepted as a systemic disease and it is known to be associated with various disorders including metabolic syndrome. High serum uric acid levels are also associated with the components of metabolic syndrome. In this study, we aimed to determine serum uric acid levels in patients with psoriasis and the association of uric acid levels with disease activity by taking the presence of metabolic syndrome criteria into account, since it is one of the most important factors that affect serum uric acid levels. In this cross-sectional study, we evaluated 70 psoriasis patients and 70 healthy individuals who were matched with the patients according to the presence of metabolic syndrome. We evaluated the demographic features, levels of serum uric acid, Psoriasis Area Severity Index (PASI) scores, presence of psoriatic arthritis, nail involvement, and metabolic syndrome criteria of the patients. Serum uric acid levels of psoriasis patients were significantly higher than those of controls. There was a positive correlation between PASI scores and serum uric acid levels of the patients. As hyperuricemia had a close relationship with psoriasis and PASI scores, we suggest monitoring patients with psoriasis for serum uric acid levels during treatment and follow-up.

    Full Text Available Abstract Background In the past decades, the prevalence of candidemia has increased significantly and drug resistance has also become a pressing problem. Overexpression of CDR1, an efflux pump, has been proposed as a major mechanism contributing to the drug resistance in Candida albicans. It has been demonstrated that biological fluids such as human serum can have profound effects on antifungal pharmacodynamics. The aim of this study is to understand the effects of serum in drug susceptibility via monitoring the activity of CDR1 promoter of C. albicans. Results The wild-type C. albicans cells (SC5314 but not the cdr1/cdr1 mutant cells became more susceptible to the antifungal drug when the medium contained serum. To understand the regulation of CDR1 in the presence of serum, we have constructed CDR1 promoter-Renilla luciferase (CDR1p-RLUC reporter to monitor the activity of the CDR1 promoter in C. albicans. As expected, the expression of CDR1p-RLUC was induced by miconazole. Surprisingly, it was repressed by serum. Consistently, the level of CDR1 mRNA was also reduced in the presence of serum but not N-acetyl-D-glucosamine, a known inducer for germ tube formation. Conclusion Our finding that the expression of CDR1 is repressed by serum raises the question as to how does CDR1 contribute to the drug resistance in C. albicans causing candidemia. This also suggests that it is important to re-assess the prediction of in vivo therapeutic outcome of candidemia based on the results of standard in vitro antifungal susceptibility testing, conducted in the absence of serum.

    Glycated hemoglobin Alc (HbAlc) is an important indicator of blood glucose monitor, which reflects the average blood glucose level of 2-3 months before the detection. In the patients with chronic renal failure (CRF), some factors can affect the level of HbA 1 c, such as anemia, acidosis, oxidative stress, in-sulin resistance, hemodialysis and application of erythropoietin (EPO). Glycated serum protein (GSP) re-flects the average blood glucose level of 2-3 weeks before the detection,which is only associated with the plas-ma proteins. It is almost not affected by hemoglobin, EPO treatment and other factors mentioned above and is more sensitive to the changes of blood glucose in a short period. GSP may be more appropriate for glucose mo-nitoring than HbAlc to diabetics with renal failure.%糖化血红蛋白(Hb)A1c是血糖监测的苇要指标,反映检测前2~3个月的平均血糖水平.慢性肾功能衰竭(CRF)患者存在贫血、酸中毒、氧化应激、胰岛素抵抗、血液透析及促红细胞生成素(EPO)的应用等因素,对HbA1c的测定会造成影响.糖化血清蛋白(GSP)反映检测前2~3周的平均血糖水平,仅受血浆蛋白的影响,几乎不受血红蛋白和EPO治疗等以上因素的影响,且对短时间内的血糖变化更为敏感.将GSP作为糖尿病肾功能衰竭患者血糖监测指标可能比HbA1c更理想.

    Full Text Available OBJECTIVE: The aim of this study was to examine serum prealbumin (PA levels in patients with tuberculosis and lung cancer, and to evaluate the correlations of serum PA levels with clinicopathological characteristics. METHOD: Total 760 patients were included in the study: 320 patients with tuberculosis, 320 patients with lung cancer, and 120 healthy subjects. Serum PA was detected using a biochemical analyzer to determine the value of serum PA in the diagnosis and therapeutic response of tuberculosis. RESULTS: Compared to lung cancer and healthy individuals, TB patients were more frequent in suffering from low serum PA (75.0% vs.30.9% vs.6.7%,P20 mm/h and smoking status (≥ 20 pack × years were associated with low serum PA levels of TB patients, while ECOG performance status (≥ 2 was associated with low serum PA levels of lung cancer patients. The change of serum PA levels was in accordance with the therapeutic effects of anti-TB drugs, which might present a valuable and objective indicator for monitoring the therapeutic effects of TB drugs on TB patients. CONCLUSION: Low serum prealbumin levels are very common in TB patients and can be served as a potential indicator for differential diagnosis of lung cancer and monitoring the therapeutic effects of TB drugs.

    A decrease in serum albumin concentrations is an almost inevitable finding in disease states, and is primarily mediated in the acute phase by alterations in vascular permeability and redistribution. This change is not disease specific but marked changes that persist are generally associated with a poorer prognosis. Critical appraisal of long-standing practices and the availability of alternative colloid solutions have led to a reduction in albumin replacement therapy, and a widespread tolerance of lower albumin concentrations in patients. The factors determining serum albumin concentrations, their measurement and the implications of hypoalbuminaemia are reviewed. The clinical value of serum albumin measurement is discussed.

    This is a brief report on LEReC recombination monitor design considerations. The recombination produced Au78+ ion rate is reviewed. Based on this two designs are discussed. One is to use the large dispersion lattice. It is shown that even with the large separation of the Au78+ beam from the Au79+ beam, the continued monitoring of the recombination is not possible. Accumulation of Au78+ ions is needed, plus collimation of the Au79+ beam. In another design, it is shown that the recombination monitor can be built based on the proposed scheme with the nominal lattice. From machine operation point of view, this design is preferable. Finally, possible studies and the alternative strategies with the basic goal of the monitor are discussed.

    Full Text Available Serum is widely used for the purpose of monitoring and diagnosis support for most of poultry diseases. In the case of the serum plate agglutination test (SPA, commonly used to detect antibodies for Salmonella Pullorum (SP, Mycoplasma gallisepticum (MG and Mycoplasma synoviae (MS, serum cannot be frozen because it may result in false positive. Without freezing, serum can last only for a few days. In this experiment, glycerin was evaluated as a serum preservering agent. About 50 samples for each disease and analyzed by SPA test previously were separated. Glycerin was added to serum from commercial chickens, with and without antibodies for SP, MG and MS, in the proportion of 1:1 (serum:glycerin and kept at refrigerated conditions (2 to 8 ºC. For four years they were tested by the SPA, initially weekly, afterward monthly and then annually. The results show that serum with glycerin give consistent and valid results according to the kind of antibodies present for the period tested. Sera that glycerin was not added to, the results were valid only for the first week. From the second week on, microbial growth affected the test results of the sera without glycerin. Our investigation shows that glycerin can be used to preserve chicken serum for SPA under refrigerated conditions. It is an easy, simple and cheap procedure that can extend serum shelf life, useful mainly for control sera.

    A case of a 32-year-old XY genotype female is described, presenting with mediastinal and abdominal lymphadenopathy and associated with an elevated serum angiotensin I converting enzyme (SACE) level. Lymph node histology showed a malignant dysgerminoma of ovarian origin. Combined chemotherapy led to a radiological regression of the lymphadenopathy and coincided with a decrease in SACE concentration. The authors suggest that SACE may be a marker for disseminated germinoma tumours and may be useful for monitoring treatment.

    Objective To study whether liver cirrhosis associated with Helicopacter pylori (H. pylori)infection will induce increased serum ammonia and whether the peripheral serum ammonia reflects the level of portal vein serum ammonia. Methods Blood was taken from the portal vein and the cubital vein in cirrhotic patients with and without H.pylori infection and non-cirrhotic patients (splenic rupiure) with and without H. pylori infection, and the serum ammonia was measured. Results The mean levels of serum ammonia in the group of cirrhotic patients with H. pylori infection were 167.82±8.97 μmol/L (pertal vein) and 142.2±13.35 μmol/L (cubital vein). They were increased significantly as compared with cirrhotic patients without H.pyiori infection(47.68±12.03 μmol/L portal vein and 37.23±7.04 μmol/L cubital vein),and also compared with the groups of splenic rupture patients with and without H. pylori infection (P<0.0t).There was no significant difference between the serum ammonia level of the cubital vein and pertal vein(P>0.05). Conclusions H.pylori intection can induce an increase in serum ammonia in patients with liver dysfunction,and the peripheral serum ammonia measurement may replace the portal vein serum ammania as a monitoring method. Eradication of H.pylori in cirrhotic patients may prevent hepatic encephalopathy(HE).

    A clinical blood serum mercury test of 111 dentists and auxiliaries revelaed that more than 50% had above normal serum mercury levels. This study showed that there may be a mercury health hazard in some dental environments. Acute mercury poisoning may be corrected simply by removing the cause, but long-term chronic effects are not known. Frequent screening of offices and personnel is advised. Experience reported here indicates that large amounts of mercury vapor are emitted when an amalgam carrier is heated over a flame ot dislodge particles, and also, that water-covered amalgam scrap relesases mercury vapor.

    The incidence and cause of premature corpora lutea failure and the response to luteinizing hormone treatment was investigated in superovulated dairy goats. Does were treated with 1000 IU pregnant mare serum gonadotropin intramuscularly, followed by either luteinizing hormone (treated group) or saline (control group). Serum progesterone concentrations were used to monitor corpus luteum function. The dose of pregnant mare serum gonadotropin used induced superovulation in a majority of the does, but the responses varied depending on the time of year. Premature regression of the corpora lutea occurred in 4 of 18 does after pregnant mare serum gonadotropin treatment, but there was no difference in the incidence of corpora lutea failure between treated and control groups. Decreases in serum progesterone concentrations were evident by day 3 after ovulation in does that experienced corpora lutea failure indicating this to be the critical time for premature regression of the corpora lutea in superovulated does.

    Waste Reduction Operations Complex (WROC) facilities are located at the Idaho National Engineering Laboratory (INEL). The overall goal for the Pollution Prevention/Waste Minimization Unit is to identify and establish the correct amount of waste generated so that it can be reduced. Quarterly, the INEL Pollution Prevention (P2) Unit compares the projected amount of waste generated per process with the actual amount generated. Examples of waste streams that would be addresses for our facility would include be are not limited to: Maintenance, Upgrades, Office and Scrap Metal. There are three potential sources of this variance: inaccurate identification of those who generate the waste; inaccurate identification of the process that generates the waste; and inaccurate measurement of the actual amount generated. The Materials Monitoring Program was proposed to identify the sources of variance and reduce the variance to an acceptable level. Prior to the implementation of the Material Monitoring Program, all information that was gathered and recorded was done so through an informal estimation of waste generated by various personnel concerned with each processes. Due to the inaccuracy of the prior information gathering system, the Material Monitoring Program was established. The heart of this program consists of two main parts. In the first part potential waste generators provide information on projected waste generation process. In the second part, Maintenance, Office, Scrap Metal and Facility Upgrade wastes from given processes is disposed within the appropriate bin dedicated to that process. The Material Monitoring Program allows for the more accurate gathering of information on the various waste types that are being generated quarterly.

    AIM: The diagnosis of cholangiocarcinoma is often difficult,making management approaches problematic. A reliable serum marker for cholangiocarcinoma would be a useful diagnostic test. The aims of our study were to evaluate the usefulness of a serum CA19-9 determination in the diagnosis of cholangiocareinoma.METHODS: We prospectively measured serum CA19-9 and CEA concentrations in patients with cholangiocarcinoma (n=35), benign biliary diseases (n=92), and healthy individuals n=15). Serum CA19-9 and CEA concentrations were measured by an immunoradiometric assay without knowledge of the clinical diagnosis.were 77.14% and 68.57%, respectively. When compared with the benign biliary diseases group, the true negative rates of serum CA19-9 and CEA were 84.78% and 81.52%,respectively, The false positive rates of serum CA19-9 and CEA were 15.22% and 18.48%, whereas the accuracy of serum CA19-9 and CEA were 82.68% and 77.95%,respectively. Serum CA19-9 and CEA concentrations were significantly elevated (P<0.001 and P<0.05) in patients with patients undergoing curative resection of cholangiocareinoma,the mean serum CA19-9 concentration was decreased from however, no correlation was found between serum CEA and CA19-9 concentrations (r=0.036).CONCLUSION: These data suggest that the serum CA19-9 determination is a usefol addition to the available tests for the differential diagnosis of cholangiocareinoma. Serum CA19-9 is an effective tumor marker in diagnosing cholangiocareinoma,deciding whether the tumor has been radically resected and monitoring effect of treatment.

    Gastric adenocarcinoma is an aggressive cancer with poor prognosis. Blood based biomarkers of gastric cancer have the potential to improve diagnosis and monitoring of these tumors. Proteins that show altered levels in the circulation of gastric cancer patients could prove useful as putative biomarkers. We used an iTRAQ-based quantitative proteomic approach to identify proteins that show altered levels in the sera of patients with gastric cancer. Our study resulted in identification of 643 proteins, of which 48 proteins showed increased levels and 11 proteins showed decreased levels in serum from gastric cancer patients compared to age and sex matched healthy controls. Proteins that showed increased expression in gastric cancer included inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4), Mannose-binding protein C (MBL2), sex hormone-binding globulin (SHBG), insulin-like growth factor-binding protein 2 (IGFBP2), serum amyloid A protein (SAA1), Orosomucoid 1 (ORM1) and extracellular superoxide dismutase [Cu–Zn] (SOD3). We used multiple reaction monitoring assays and validated elevated levels of ITIH4 and SAA1 proteins in serum from gastric cancer patients. Biological significance Gastric cancer is a highly aggressive cancer associated with high mortality. Serum-based biomarkers are of considerable interest in diagnosis and monitoring of various diseases including cancers. Gastric cancer is often diagnosed at advanced stages resulting in poor prognosis and high mortality. Pathological diagnosis using biopsy specimens remains the gold standard for diagnosis of gastric cancer. Serum-based biomarkers are of considerable importance as they are minimally invasive. In this study, we carried out quantitative proteomic profiling of serum from gastric cancer patients to identify proteins that show altered levels in gastric cancer patients. We identified more than 50 proteins that showed altered levels in gastric cancer patient sera. Validation in a large cohort of well

    Modified Atkins diet is a treatment option for patients with pharmacoresistant epilepsy that is not suitable for surgery. In the last few years, we have tried dietary treatment added to antiepileptic drugs (AEDs) in adult patients with severe epilepsy. To examine a possible pharmacokinetic interaction between the modified Atkins diet and AEDs. In four patients, AED serum concentrations were measured before onset and after 4 and 12 weeks on the diet. The patients used combinations of two or three AEDs, including carbamazepine, clobazam, lamotrigine, nitrazepam, oxcarbazepine, valproate, zonisamide, and topiramate. The patients did not change the type or dose of their AEDs during the diet period. After 12 weeks on the diet, the average serum concentrations of the respective AEDs were reduced by 35% (range 6-46%) compared to prediet values. Modified Atkins diet used as add-on therapy to AEDs in four patients with drug resistant seizures caused a considerable decrease in AED serum concentrations. In individual patients, this could be of clinical relevance, and we recommend that AED serum concentrations should be closely monitored when offering this diet to adults with epilepsy. © 2014 John Wiley & Sons A/S.

    Full Text Available Background: Chronic autoimmune urticaria (CAU is one of the most challenging therapeutic problems faced by a dermatologist. Recently, weekly autologous serum injections have been shown to induce a prolonged remission in this disease. Aim: To evaluate the efficacy of repeated autologous serum injections in patients with CAU. Materials and Methods: Seventy patients of CAU were prospectively analyzed for the efficacy of nine consecutive weekly autologous serum injections with a post-intervention follow-up of 12 weeks. Total urticaria severity score (TSS was monitored at the baseline, at the end of treatment and lastly at the end of 12 weeks of follow up. Response to treatment was judged by the percentage reduction in baseline TSS at the end of treatment and again at the end of 12 weeks-follow-up. Results: Out of the 70 patients enrolled, 11 dropped out of the injection treatment after one or the first few doses only. Among the rest of 59 patients, only 7 patients (12% went into a partial or complete remission and remained so over the follow-up period of 12 weeks. Forty patients (68% did not demonstrate any significant reduction in TSS at the end of the treatment period. Rest of the 12 patients showed either a good or excellent response while on weekly injection treatment, but all of them relapsed over the follow-up period of 12 weeks. Conclusion: Autologous serum therapy does not seem to lead to any prolonged remission in patients of CAU.

    Trichloroethylene (TCE) is an industrial solvent with widespread occupational exposure and also a major environmental contaminant. Occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) is an autoimmune disease and it has become one major hazard in China. In this study, sera from 3 healthy controls and 3 OMLDT patients at different disease stages were used for a screening study by 2D-DIGE and MALDI-TOF-MS/MS. Eight proteins including transthyretin (TTR), retinol binding protein 4 (RBP4), haptoglobin, clusterin, serum amyloid A protein (SAA), apolipoprotein A-I, apolipoprotein C-III and apolipoprotein C-II were found to be significantly altered among the healthy, acute-stage, healing-stage and healed-stage groups. Specifically, the altered expression of TTR, RBP4 and haptoglobin were further validated by Western blot analysis and ELISA. Our data not only suggested that TTR, RBP4 and haptoglobin could serve as potential serum biomarkers of OMLDT, but also indicated that measurement of TTR, RBP4 and haptoglobin or their combination could help aid in the diagnosis, monitoring the progression and therapy of the disease.

    Full Text Available The aim of this study was to investigate serum IL17 levels in patients with Crohn’s disease (CD and to investigate the relationship between serum IL17 levels with disease activity. Methods. Fifty patients with CD and sex- and age-matched 40 healthy controls were included in the study. The serum IL17 levels, complete blood count, blood chemistry, erythrocyte sedimentation rate (ESR, and C-reactive protein (CRP levels were measured, and Crohn’s disease activity was calculated using Crohn’s disease activity index (CDAI. Results. The mean serum IL17 level of CD patients did not differ from those of healthy controls (P>0.05. There was no difference between the mean serum IL levels of active CD patients and of quiescent CD patients (P>0.05. However, the mean IL17 level of active patients was lower than of control subjects (P=0.02. Serum IL17 was not correlated with inflammatory markers (ESR, CRP, white blood count, platelet count, and albumin and CDAI. Conclusions. Peripheral blood serum IL17 levels of CD patients were not higher than of healthy controls, and also, serum IL17 level was not correlated with clinical disease activity. Peripheral IL17 measurement is not a useful tool for detecting and monitoring Crohn’s disease which is understood to have complex etiopathogenesis.

    Recent studies suggest that high levels of serum uric acid of very early life are a result of the in-utero environment and may lead to elevated blood pressure (BP) in adulthood. However, serum uric acid levels can change throughout life. We investigated the effect of serum uric acid levels in childhood on the BP tracking and analysed BP according to changes in serum uric acid levels in early life. A total of 449 children from the Ewha Birth and Growth Cohort study underwent at least 2 follow-up examinations. Data were collected across 3 check-up cycles. Serum uric acid levels, BP, and anthropometric characteristics were assessed at 3, 5, and 7 years of age. Children with a serum uric acid level higher than the median values had significantly increased systolic BP (SBP) and diastolic BP at 3 years of age. Baseline serum uric acid levels measured at 3 years of age, significantly affected subsequent BP in the sex and body mass index adjusted longitudinal data analysis (P uric acid over time, subjects with high uric acid levels at both 3 and 5 years of age had the highest SBP at 7 years of age. These findings suggest the importance of maintaining an adequate level of serum uric acids from the early life. Appropriate monitoring and intervention of uric acid levels in a high-risk group can reduce the risk of a future increased BP.

  6. Monitoring Leverage

    We argue that leverage is a central element of economic cycles and discuss how leverage can be properly monitored. While traditionally the interest rate has been regarded as the single key feature of a loan, we contend that the size of the loan, i.e., the leverage, is in fact a more important...... measure of systemic risk. Indeed, systemic crises tend to erupt when highly leveraged economic agents are forced to deleverage, sending the economy into recession. We emphasize the importance of measuring both the average leverage on old loans (which captures the economy's vulnerability) and the leverage...... offered on new loans (which captures current credit conditions) since the economy enters a crisis when leverage on new loans is low and leverage on old loans is high. While leverage plays an important role in several economic models, the data on leverage is model-free and simply needs to be collected...

    Metabolomics is a promising "omics" field in systems biology; its objective is comprehensive analysis of low-molecular-weight endogenous metabolites in a biological sample. It could enable mapping of perturbations of early biochemical changes in diseases and hence provide an opportunity to develop predictive biomarkers that could result in earlier intervention and provide valuable insights into the mechanisms of diseases. Because of the possible discovery of clinically relevant biomarkers, metabolomics has potential advantages that routine approaches to clinical diagnosis do not. Monitoring specific metabolite levels in serum, the most commonly used biofluid in metabolomics, has become an important way of detecting the early stages of a disease. Serum is a readily accessible and informative biofluid, making it ideal for early detection of a wide range of diseases, and analysis of serum has several advantages over analysis of other biofluids. Metabolite profiles of serum can be regarded as important indicators of physiological and pathological states and may aid understanding of the mechanism of disease occurrence and progression on the metabolic level, and provide information enabling identification of early and differential metabolic markers of disease. Analysis of these crucial metabolites in serum has become important in monitoring the state of biological organisms and is widely used for diagnosis of disease. Emerging metabolomics will drive serum analysis, facilitate and improve the development of disease treatments, and provide great benefits for public health in the long-term.

    Therapeutic drug monitoring (TDM) of antiepileptic drugs (AEDs) in serum is frequently used in clinical settings however saliva could be an alternative to measure free concentration of drugs. In the present study, we observed the possible correlation of VPA concentration between serum and saliva in persons with epilepsy (PWE). A total of 59 paired serum and saliva samples were assayed from 65 consecutive PWE (51 males and 14 females; age range 9-65 years). Patients were subjected to either VPA monotherapy or its combination with other AEDs for at least three months. Steady state trough concentration of unbound VPA drug was quantified using HPLC. The correlation between serum and saliva free VPA concentration was evaluated. Out of 65 patients, 27 were on monotherapy of VPA and 38 were on VPA with other antiepileptic drugs. Saliva VPA concentration significantly correlated with serum free VPA concentration (psaliva VPA concentration with the daily dose (p>0.05) respectively. Our study reveals that serum and saliva VPA concentrations are significantly associated in PWE. These associations may facilitate monitoring and evaluation of VPA levels non-invasively for PWE.

    The array biosensor provides the capability for simultaneously measuring titers of antibody against multiple antigens. Human antibodies against four different targets, tetanus toxin, diphtheria toxin, staphylococcal enterotoxin B (SEB) and hepatitis B, were measured simultaneously in sera from eight different donors in a single assay and titers were determined. The assays could measure amounts of bound antibody as low as approximately 100 fg. Each individual serum exhibited a different pattern of reactivity against the four target antigens. Applications of this biosensor capability include monitoring for exposure to pathogens and for efficacy of vaccination.

    Precise monitoring of the rapidly changing immune status during the course of a disease requires multiplex analysis of cytokines from frequently sampled human blood. However, the current lack of rapid, multiplex, and low volume assays makes immune monitoring for clinical decision-making (e.g., critically ill patients) impractical. Without such assays, immune monitoring is even virtually impossible for infants and neonates with infectious diseases and/or immune mediated disorders as access to their blood in large quantities is prohibited. Localized surface plasmon resonance (LSPR)-based microfluidic optical biosensing is a promising approach to fill this technical gap as it could potentially permit real-time refractometric detection of biomolecular binding on a metallic nanoparticle surface and sensor miniaturization, both leading to rapid and sample-sparing analyte analysis. Despite this promise, practical implementation of such a microfluidic assay for cytokine biomarker detection in serum samples has not been established primarily due to the limited sensitivity of LSPR biosensing. Here, we developed a high-throughput, label-free, multiarrayed LSPR optical biosensor device with 480 nanoplasmonic sensing spots in microfluidic channel arrays and demonstrated parallel multiplex immunoassays of six cytokines in a complex serum matrix on a single device chip while overcoming technical limitations. The device was fabricated using easy-to-implement, one-step microfluidic patterning and antibody conjugation of gold nanorods (AuNRs). When scanning the scattering light intensity across the microarrays of AuNR ensembles with dark-field imaging optics, our LSPR biosensing technique allowed for high-sensitivity quantitative cytokine measurements at concentrations down to 5–20 pg/mL from a 1 µL serum sample. Using the nanoplasmonic biosensor microarray device, we demonstrated the ability to monitor the inflammatory responses of infants following cardiopulmonary bypass (CPB
