    Full Text Available Growing knowledge about the cytokine network response has led to a better comprehension of mechanisms of pathologies and to the development of new treatments with biological drugs, able to block specific molecules of the immune response. Indeed, when the cytokine production is deregulated, diseases often occur. The understanding of the physiological mechanism of the cytokine network would be useful to better comprehend pathological conditions. Moreover, since the immune system and response change their properties with development, differences in patients' age should be taken into account, both in physiological and in pathological conditions. In this study, we analyzed the profile of 48 cytokines and chemokines in the serum of healthy subjects, comparing adults (≥18 years with young children and children (1–6 and 7–17 years. We found that a certain number of cytokines were not being produced in healthy subjects; others showed a constant serum level amongst the groups. Certain cytokines exhibited a downward or an upward trend with increasing age. The remaining cytokines were up- or downregulated in the group of the children with respect to the other groups. In conclusion, we drew some kinds of guidelines about the physiological production of cytokines and chemokines, underling the difference caused by aging.

    Full Text Available Introduction. Serbia is the country with extremely low birth rate and a relatively high percentage of preterm deliveries (8%. With this in mind, discovering new diagnostic methods that could be used for the prediction of preterm delivery is of great importance. In this study we tried to determine whether bacterial vaginosis and chlamydial infection could provoke preterm delivery by activation of systemic cytokine network. Objective. The aim of this study was to determine serum levels of proinflammatory cytokines (IL-1β, IL-8, IFN-γ, IL-6 and TNF-α in pregnant women with symptoms of preterm delivery and to make correlation between these parameters and the presence of bacterial vaginosis or chlamydial infection. Method. In the serum of 35 pregnant women, which were divided in groups according to the presence or absence of bacterial vaginosis and chlamydial infection, commercial ELISA tests for proinflammatory cytokines were performed. Results. The serum level of IFN-γ was significantly increased in pregnant women having chlamydial infection, as well as the level of IL-1β in women with bacterial vaginosis. The levels of TNF-α, IL-6 and IL-8 were not significantly different between the investigated groups. Conclusion. The preliminary results obtained in this research point out the possibility that not only intrauterine or systemic infections, but also bacterial vaginosis and chlamydial infection can cause a partial activation of systemic cytokine network and contribute to the occurrence of preterm delivery.

    Full Text Available Cytokines are important factors of the immune system in autoimmune diseases such as multiple sclerosis (MS in which damage caused by oxidants plays a major role in the pathology. Melatonin secreted by the pineal gland has recently been considered as an antioxidant. The purpose of this study was to determine the relationship between melatonin and cytokines in patients with MS. Thirty patients with MS and 30 healthy controls were selected. Serum levels of melatonin and cytokines, including interleukin-4, interferon-γ, and tumor necrosis factor alpha (TNF-α, were detected in all participants by the enzyme-linked immunosorbent assay (ELISA method. There was a significant difference between patient and control groups in the levels of melatonin and TNF-α. Also, no significant correlation between the serum levels of melatonin and cytokines in both patient and control groups was seen. We concluded that decrease of melatonin and subsequent increase of pro-inflammatory cytokine, TNF-α, could be a factor in the inflammatory reactions in the pathologic process of MS.

    Tributyltin (TBT), a toxic environmental contaminant, has been widely utilized for various industrial, agricultural and household purposes. Its usage has led to a global contamination and its bioaccumulation in aquatic organisms and terrestrial mammals. Previous studies suggest that TBT has debilitating effects on the overall immune function of animals, rendering them more vulnerable to diseases. TBT (at concentrations that have been detected in human blood) alters secretion of inflammatory cytokines from human lymphocytes ex vivo. Thus, it is important to determine if specified levels of TBT can alter levels of cytokines in an in vivo system. Mice were exposed to biologically relevant concentrations of TBT (200, 100 or 25 nM final concentrations). The quantitative determination of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL2, IL5, IL7, IL12βp40, IL13, IL15, keratinocyte chemoattractant (KC), macrophage inflammatory protein 1β (MIP), MIP2 and regulated on activation normal T-cell-expressed and secreted (RANTES) was performed in mouse sera by MAGPIX analysis and Western blot. Results indicated alterations (both decreases and increases) in several cytokines. The pro-inflammatory cytokines IFNγ, TNFα, IL-1β, IL-2, IL5, IL12βp40 and IL-15 were altered as were the chemokines MIP-1 and RANTES and the anti-inflammatory cytokine IL-13. Increases in IFNγ and TNFα were seen in the serum of mice exposed to TBT for less than 24 h. Levels of IL1β, IL-12 βp40, IL-5 and IL-15 were also modulated in mouse serum, depending on the specific experiment and exposure level. IL-2 was consistently decreased in mouse serum when animals were exposed to TBT. There were also TBT-induced increases in MIP-1β, RANTES and IL-13. These results from human and murine samples clearly suggest that TBT exposures modulate the secretion inflammatory cytokines.

  7. The Importance of Serum Cytokine Levels in Febrile Neutropenia

    Full Text Available The most important evaluation of the neutropenic patients is to determine the risk group. The desired approach to patients with low risks should be either not to hospitalize or to hospitalize for a short period of time which both decreases the cost and exposure to the resistant flora. The early diagnosis of sepsis in patients with high risk may be life saving. Recently, the determination of low and high-risk groups only by the clinical variables is not found to be a reliable method. The laboratory parameters supported by the clinical variables may be more practical. The determination of serum cytokines levels in febrile neutropenia may be helpful for the early risk diagnosis, new treatment approaches, and prognosis.

    Cytokine-mediated regulation of chronic intestinal helminth infections is well documented. The present study reports the serum cytokine responses in 38 ascariasis (stool samples positive for Ascaris lumbricoides ova) and toxocariasis (seropositive) patients, 8 ascariasis-positive and toxocariasis-seronegative patients, 22 endemic, normal, healthy subjects residing in areas hyperendemic for ascariasis and 16 normal healthy subjects residing in a low-endemic area in India. The results indicated T-helper type-2-type cytokine responses in ascariasis and toxocariasis (seropositive) and ascariasis-positive and toxocariasis-seronegative patients. The important observation was that both patients and healthy individuals in ascariasis-hyperendemic areas had significantly higher interleukin-5 (IL-5) responses than non-endemic control subjects. The altered immune responses of patients in areas hyperendemic of ascariasis may have further implications. Earlier reports suggest that the geohelminth parasites in endemic areas may modulate the immune response to oral vaccines. A critical role for IL-5 in the immune response against challenge infection consistent with the association of type-2 cytokines with vaccine-mediated protection has been reported. Furthermore, co-infection by pathogens that elicit opposing immune responses, particularly helminths vs HIV and tuberculosis, could influence the infection dynamics, progression and immunoprophylaxis of the diseases they cause. Further studies are warranted to ascertain these findings.

    Periodontal disease has been linked to systemic diseases/disorders and a low-grade systemic inflammatory status originated from periodontitis has been proposed as a possible explanation for this association. This study evaluates the relationship, early in pregnancy, between gingival crevicular fluid (GCF) and serum levels of a panel of cytokines that have been implicated in PTB and periodontal disease. One hundred pregnant women aged 18-35 years old with a gestational age up to 20 weeks were included (mean±SD gestational age:16.1±3.5 weeks). Four periodontal sites per subject were randomly selected for GCF collection. Serum and GCF levels of IL-1β, IL-6, IL-8, IL-10, IL-12p70 and TNF-α were analyzed using a cytometric bead array. Regression and correlation analyses were used to assess the relationship between serum and GCF cytokine levels. Participants had widespread periodontal inflammation but limited periodontal destruction. Cytokine levels were significantly higher in GCF than serum for all cytokines but IL-10. GCF levels had small but significant effect on serum levels for IL-10 (β=0.34±0.09, p<0.01), IL-12p70 (β=0.48±0.08, p<0.01) and TNF-α (β=0.29±0.09, p<0.01). Periodontal probing depth and bleeding on probing were significantly associated with GCF levels for IL-1β, IL-6 and IL-8; however, they had negligible effect on serum cytokine levels. Correlation between GCF and serum levels was non-significant, except for IL-12p70, which showed a significant but small correlation between the two sources (r=0.32, p=0.001). GCF cytokine levels were not strongly associated with serum cytokine levels in pregnant women with widespread periodontal inflammation but limited periodontal destruction.

    Full Text Available Psoriasis is a chronic inflammatory skin disease. It is assumed that the plaque phenotype of psoriasis is associated with T helper (Th 1 immune response activation, while the guttate phenotype is associated with the Th17 immune response. Previous investigations of differences in the serum levels of cytokines relative to the clinical psoriatic phenotype have yielded conflicting results. This study compared the levels of circulating inflammatory cytokines and LL-37 relative to the morphological phenotype in patients with psoriasis. Seventy-four age-matched patients with psoriasis (32 with guttate psoriasis and 42 with plaque psoriasis and 12 healthy controls were included. A multiplex cytokine assay and enzyme-linked immunosorbent assay were used to measure levels of Th1- and Th17-derived cytokines and LL-37, respectively. Circulating levels of interferon- (IFN-γ, interleukin- (IL-1RA, IL-2, and IL-23, and LL-37 were significantly higher in patients with psoriasis than in healthy controls. However, the serum levels of inflammatory cytokines (IL-7, IL-22, and IL-23 and LL-37 did not differ significantly between the guttate and plaque phenotypes of psoriasis. There was a positive correlation between serum inflammatory cytokine levels and the Psoriasis Area and Severity Index score. The findings of this study suggest that the serum levels of inflammatory cytokines reflect the disease activity rather than determine the morphological phenotype.

    Serum levels of inflammatory cytokines, for example, tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and IL-1 beta (IL-1β), are elevated in subjects with major depressive disorder (MDD). The reason why this occurs is unclear. Elevated levels of inflammatory cytokines could be a result of brain dysfunction in MDD. It is also possible that inflammatory cytokines contribute to depressive symptoms in MDD. If the first assumption is correct, one would expect levels to normalize with resolution of the depressive episode after treatment. Several studies have measured changes in cytokine levels during antidepressant treatment; however, the results vary. The purpose of this study was to pool all available data on changes in serum levels of TNFα, IL-6, and IL-1β during antidepressant treatment to determine whether these levels change. Studies were included if they used an approved pharmacological treatment for depression, patients had a diagnosis of MDD, and serum levels of TNFα, IL-6, and/or IL-1β were measured before and after treatment. Twenty-two studies fulfilled these criteria. Meta-analysis of these studies showed that, overall, while pharmacological antidepressant treatment reduced depressive symptoms, it did not reduce serum levels of TNFα. On the other hand, antidepressant treatment did reduce levels of IL-1β and possibly those of IL-6. Stratified subgroup analysis by class of antidepressant indicated that serotonin reuptake inhibitors may reduce levels of IL-6 and TNFα. Other antidepressants, while efficacious for depressive symptoms, did not appear to reduce cytokine levels. These results argue against the notion that resolution of a depressive episode is associated with normalization of levels of circulating inflammatory cytokines; however, the results are consistent with the possibility that inflammatory cytokines contribute to depressive symptoms and that antidepressants block the effects of inflammatory cytokines on the brain.

  13. Baseline levels and temporal stability of 27 multiplexed serum cytokine concentrations in healthy subjects.

    Full Text Available BACKGROUND: Cytokines are humoral molecules that elicit regulatory function in immunologic pathways. The level and type of cytokine production has become critical in distinguishing physiologic from pathologic immune conditions. Cytokine profiling has become an important biomarker discovery tool in monitoring of the immune system. However, the variations in cytokine levels in individual subjects over time in healthy individuals have not been extensively studied. In this study, we use multiplex bead arrays to evaluate 27 analytes in paired serum samples taken seven days apart from 144 healthy individuals in order to assess variations over a short time period. METHODS: Fluorescent bead-based immunoassay (Luminex was used to measure 27 analytes in serum samples. Measurements were performed on matched samples from 144 healthy donors. To assess inter-plate variability, one arbitrarily selected serum sample was analyzed on each of the first ten plates as bridge sample. RESULTS: Using the bridge sample, we showed minimal inter-plate variations in the measurement of most analytes. In measurement of cytokines from the 144 patients at two time points, we found that three cytokines (IL-2, IL-15 and GM-CSF were undetectable and five analytes (RANTES, MCP-1, VEGF, MIP-1β and PDGF-BB showed significant difference in concentrations at Day 0 compared to Day 7. CONCLUSIONS: The current study demonstrated higher variations in cytokine levels among individuals than were observed for samples obtained one week apart from identical donors. These data suggest that a serum sample from each subject for use as a baseline measurement is a better control for clinical trials rather than sera from a paired cohort.

    Coal workers' pneumoconiosis (CWP) is an occupational pulmonary disease that occurs by chronic inhalation of coal dust. CWP is divided into two stages depending on the extent of the disease, as simple pneumoconiosis (SP) and progressive massive fibrosis (PMF). In the present study, serum and bronchoalveolar lavage (BAL) cytokine (interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta (TGF-beta)) and antioxidant enzymes levels, their relation with the disease severity, and whether they can be considered as biological markers were investigated. Serum and BAL levels of IL-1 beta, IL-6, and TNF-alpha were higher in SP and PMF patient groups compared with that in active and retired miner groups. Serum and BAL IL-1 beta, IL-6, and TNF-alpha levels were also found to be higher in patients with PMF compared with the SP group. BAL superoxide dismutase (SOD), glutathione peroxidase, and catalase levels and serum SOD level were increased in both patient groups compared with the control group. In addition, mean serum and BAL TGF-beta levels were found to be increased in patients with SP compared with PMF group. Based on these results, BAL and serum cytokine and antioxidant enzymes levels were evaluated and discussed as potential biomarkers for different stages of CWP.

    Knowledge of sepsis-related end-organ inflammation in vivo is limited. We investigated the cytokine response in skin and in serum in sepsis and its relation to multiorgan failure (MOF) and survival. Cytokines were analysed in serum and in suction blister fluid of intact skin of 44 patients with severe sepsis and 15 healthy controls. Blister fluid and serum samples were collected within 48 h of the first sepsis-induced organ failure. This is a substudy of a larger follow-up study on wound healing in sepsis. Cytokine levels were higher in patients with sepsis vs. controls (interleukin [IL]-10, blisters: 65.9 vs. 4.3 pg/ml, P blisters: 41.9 vs. 0.03 pg/ml, P blister fluid than patients without MOF. In blister fluid, survivors had lower levels of IL-10 (43.3 vs. 181.9 pg/ml, P = 0.024) and bFGF (15.8 vs. 31.9 pg/ml, P = 0.006) than non-survivors. In serum, survivors had higher levels of vascular endothelial growth factor (VEGF) (152.2 vs. 14.7 pg/ml, P = 0.012) and lower levels of IL-6 (38.5 vs. 91.1 pg/ml, P = 0.011) than non-survivors. The blister fluid levels of bFGF, TNF and VEGF did not correlate with the serum levels. Cytokine responses in skin blister fluid in patients with sepsis differed from those in healthy controls. © 2016 The Acta Anaesthesiologica Scandinavica Foundation.

    AIM: To investigate whether there was a relationship between the liver functions and fibrosis scores of hepatitis B patients and their TNF-α, IFN-γ, IL-4, and TGF-β1 serum levels based on the studies of liver biopsies. METHODS: Thirty patients with chronic hepatitis B (CHB)receiving no treatment and 30 healthy individuals with negative hepatitis serology and normal values of liver biochemistry were studied. After serum samples of the patients were collected, liver needle biopsy was performed on each patient. Cytokine levels were studied by ELISA.The biopsy materials were scored based on Knodell's histological activity index.RESULTS: In comparison of cytokine levels between CHB patients and control group, TNF-α, IL-4, and TGF-β1 levels of the patients were higher in CHB patients than in the controls, while IFN-γ level was lower in the patients than in the controls. There were significant differences between the groups in TNF-α, IL-4, TGF-β1, and IFN-γ (P<0.005,0.03, 0.002, 0.0001, respectively). There was a negativecorrelation between TGF-β1 and IL-4 and IFN-γ (P<0.05),TNF-α and the other cytokines and IFN-γ and IL-4 were not correlated (P>0.05). TGF-β1 was correlated with fibrosis (P<0.05). Liver necroinflammatory activity and fibrosis and TNF-α, IL-4, and IFN-γ were not correlated (P>0.05).CONCLUSION: In the course of HBV infection and its chronic progress, cytokines play an important role. IL-4and IFN-γ are effective in the chronic progression, whileTGF-β1 is effective in the development of fibrosis. Serum cytokine levels may be effective tools in the estimation of chronic progression and fibrosis development.

In this study, as an initial effort to understand the therapeutic mechanisms of O3-AHT, we aim to examine the effect of O3-AHT on serum inflammatory cytokine levels in gouty patients. Patients and methods: Three groups of patients and healthy subjects were recruited, including the gouty (n=10, hyperuricemia (n=10, and healthy control (n=11 groups. Cytometric bead array was applied to examine 12 cytokines before (T0, during (T1, and after (T2 therapies. Results: Three cytokines, IL-8, IL-12, and MCP-1, were detectable in all participants. Before O3-AHT, the average serum levels of IL-8 and MCP-1 were higher in the gout group than in the hyperuricemia and healthy control groups, confirming the inflammation status in gouty patients. After the 5th course of O3-AHT (T1, IL-8 level was significantly increased compared to that at T0. IL-12 level was also raised at T1, although the difference did not reach statistical significance. After completing the therapy, both IL-8 and IL-12 levels decreased to levels lower than those at T0. MCP-1 level remained essentially unchanged during and after treatment. Conclusion: Our results indicate that O3-AHT induces a significant change in serum cytokine levels, suggesting that modulating the inflammatory process is one of the therapeutic

    Serum cytokine levels were explored in a combined group of patients with autoimmune liver diseases (AILDs) and separately in patients with autoimmune hepatitis (AIH) and overlap syndrome. Overall, 60 patients with AILD, among them 32 patients with AIH and 28 patients with overlap syndrome, were included in the cross-sectional study. Serum cytokine levels were measured at baseline and compared to those of 21 healthy controls. Patients with AILD had significantly higher levels of IL-6 (0.70 (range 0.17–99.86) in patients with AILD compared to 0.40 (range 0.14–2.65) in controls, p < 0.01), IL-8 (1.66 (0.45–34.58) versus 0.53 (0.35–2.38), resp., p < 0.01), and TNF-α (2.61 (0.23–120.88) versus 1.65 (0.21–7.54), resp., p < 0.01). Adjusted logistic regression analysis revealed a pronounced relation of IL-8 and AILD, 48.36 (3.63–643.60), as well as AIH, 18.54 (1.08–318.54), and overlap syndrome, 23.85 (2.37–240.23), while the associations between the level of other cytokines and AILD were assessed as nonsignificant. In the language of absolute numbers, the increase of IL-8 serum level by 1 pg/mL had increased the chance for a patient to find himself in a group of AILD by 48.36 times. Also, high IL-8 serum levels were strongly related to clinical parameters. PMID:28299346

    Study Design Cohort study. Purpose This study primarily aimed to evaluate the serum levels of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-4 in patients with lumbar radiculopathy 1 and 12 months after microdiscectomy. Overview of Literature Lumbar radiculopathy is possibly caused by inflammatory changes in the nerve root. The intraneural application of pro-inflammatory cytokines induces behavioral signs associated with pain. Anti-inflammatory cytokine treatment effectively reduces hyperalgesia. Methods The role of TNF-α and IL-4 in long-lasting lumbar radiculopathy was addressed. A total of 262 patients were recruited from Anqing Hospital, Anhui Medical University. During inclusion at 1 and 12 months, serum concentrations of TNF-α and IL-4 were analyzed by enzyme-linked immunosorbent assay, and pain intensity was reported on a 0–10 cm visual analog scale (VAS). Results Sixty six patients had VAS <3 and 196 patients had VAS ≥3. Serum concentrations of pro-inflammatory TNF-α and anti-inflammatory IL-4 in patients with lumbar radiculopathy related to disc herniation were measured at 1- and 12-month follow-up. TNF-α decreased in both VAS groups with time. In contrast, IL-4 increased in both groups at 1 month and then decreased gradually until month 12. The changes in serum levels of TNF-α and IL-4 over time between the VAS ≥3 and VAS <3 groups were significantly different. Conclusions Chronic lumbar radiculopathy may be associated with high level of pro-inflammatory substances, such as TNF-α, in serum after disc herniation, and elevated anti-inflammatory cytokine in patients with lumbar radiculopathy may indicate a favorable outcome.

This study was performed to assess serum levels of three interleukins (IL) required for Th17 differentiation (IL-1β, IL-6 and IL-23) and two specific Th17 cytokines (IL-17 and IL-22) in a group of patients with pemphigus vulgaris, at baseline, 3 weeks and 6 months after treatment. Correlations between anti-desmogleins and cytokines with disease severity as well as the influence of therapy on the above factors were assessed. Forty-three first-admitted pemphigus vulgaris patients with the active disease entered the study, but only 31 completed the study. Forty-five healthy volunteers were recruited as a control group. The patients were treated with conventional immunosuppressive therapy (oral prednisolone and azathioprine). Cytokines and anti-desmogleins were measured, using enzyme-linked immunosorbent assay. General linear model was used to evaluate the changes over time. In patients at baseline, mean serum level of IL-6 was higher, while mean levels of IL-1β and IL-22 were lower than the controls. After 3 weeks of therapy, IL-1β and IL-6 levels showed a decreasing trend, whereas IL-22 showed an increasing trend. Mean anti-desmogleins 1 and 3 values decreased significantly during the time. Anti-desmoglein values were significantly correlated with disease severity. In conclusion, IL-1β and IL-6 could be involved in the pathogenesis of pemphigus vulgaris. The positive trend of IL-22 is a new finding and should be confirmed by further studies.

    As a chronic inflammatory condition, psoriasis results from an interaction between genetic and immunologic factors in a predisposing environment. In spite of compelling evidence for the role of T cells and cytokines in psoriasis, interleukin (IL)-10 and IL-22 have not been sufficiently investigated. To assess the serum levels of IL-10 and IL-22 in patients with psoriasis compared to healthy controls. A total of 28 patients with psoriasis were compared with 28 age and sex-matched healthy subjects. Psoriasis Area and Severity Index (PASI) criteria were used to measure the severity of the disease. Serum levels of IL-10 and IL-22 were measured in both groups and compared. The mean serum level of IL-10 was 89.5±18.7 in patients compared to 117.2±23.4 pg/ml in the controls (p=0.36). Also, serum level of IL-22 was 284.1±49.7 in patients versus 425.4±82.8 pg/ml in control group (p=0.17). There was a significant direct correlation between levels of IL-10 and IL-22 in patients group (p=0.0005). The clinical severity of psoriasis was significantly correlated with high levels of IL-22 (ppsoriasis.

    Full Text Available Background: The mumps virus is frequently the causative agent of parotitis. There has been no study on serum cytokine levels of acute mumps parotitis except for a few which document cytokine levels in cerebrospinal fluid of mumps meningitis. It is with this notion, our study aimed to find Th1/Th2 cytokine levels from patients with acute mumps parotitis. Materials and Methods: Concentrations of mumps-specific IgM, mumps, measles, rubella-specific IgG antibody, and Th1/Th2 cytokines, namely interferon-g (IFN-g, interleukin-2 (IL-2, IL-4, and IL-10 were measured simultaneously in serum from 74 patients (42 pediatric and 32 adult cases, 40 healthy subjects (20 pediatric and 20 adults and in the supernatant of peripheral blood mononuclear cells stimulated with mumps virus genotype C which served as the positive control. Statistical significance was analyzed between each group by means of Mann-Whitney U-test, Kruskal-Wallis test, and Spearman′s rank correlation coefficient test. Results: IgM positivity confirmed acute infection in all 74 patients and of these 67 were vaccinated cases; however, very few of them (10/67 were positive for mumps IgG. We found that IFN-g, IL-2, and IL-10 showed a statistically significant increase in both pediatric and adult patients with acute mumps infection when compared to healthy controls and values were comparable to the positive control. Conclusion: The Th1 cells play important roles during the acute phase of mumps parotitis.

    The effects of different doses of tylosin on serum cytokine concentrations were investigated in healthy and lipopolysaccharide-treated mice. The mice were divided into seven groups. Lipopolysaccharide (LPS) was injected into the positive control group. The other six groups received three different tylosin doses concurrently without or with LPS: 10 mg/kg, 100 mg/kg, 500 mg/kg, 10 mg/kg + LPS, 100 mg/kg + LPS and 500 mg/kg + LPS. After treatment, serum samples were collected at 0, 1, 2, 3, 6, 12 and 24 hours. Serum tumour necrosis factor alpha (TNFalpha), interleukin 1beta (IL1beta) and IL10 levels were determined by enzyme-linked immunosorbent assay (ELISA). Tylosin doses of 10 and 100 mg/kg induced no cytokine production in the healthy mice. Tylosin at 500 mg/kg had no effect on TNFalpha or IL1beta production, but it induced IL10 production in healthy mice. All doses of tylosin reduced the elevated TNFalpha and IL1beta in LPS-treated mice but increased their IL10 levels. In conclusion, these data suggest that tylosin has an immunomodulatory effect at the dose recommended for use against infection.

    Full Text Available Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways. Studies have demonstrated the presence of T-helper 2 lymphocytes in the lung of patients with asthma. These cells are involved in cytokine production that regulates immunoglobulin synthesis. Recognizing that T cell interaction with antigens/allergens is key to the development of inflammatory diseases, the aim of this study is to evaluate the anti-inflammatory potential of cannabidiol (CBD in this setting. Asthma was induced in 8-week-old Wistar rats by ovalbumin (OVA. In the last 2 days of OVA challenge animals received CBD (5 mg/kg, i.p. and were killed 24 hours after. The levels of IL-4, IL-5, IL-13, IL-6, IL-10, and TNF-α were determinate in the serum. CBD treatment was able to decrease the serum levels of all analyzed cytokines except for IL-10 levels. CBD seems to be a potential new drug to modulate inflammatory response in asthma.

    Background Although a large number of studies have investigated possible relationships among serum levels of vitamin D or cytokines with disease progress and prognosis, similar studies on self-reported symptoms are still controversial. The overall objective of this study was to look into the association between serum levels of vitamin D or cytokines with self-reported symptoms related to musculoskeletal pain, sleep disorders, and premenstrual syndrome (PMS) in healthy adult women. Subjects and methods Venous blood samples were collected from 117 healthy adult women, and serum levels of vitamin D, pro-inflammatory cytokines (IL-1β, IL-6, IL-8, IL-17, IFN-γ, and TNF-α) and anti-inflammatory cytokines (IL-4, IL-10, and IL-13) were measured. Groups were tested for differences in single parameters, pro-:anti-inflammatory cytokine ratios, and differences in multivariate patterns. Results There were no significant associations between serum levels of vitamin D and any of the self-reported symptoms studied. However, serum levels of certain pro-inflammatory cytokines were significantly higher in subjects with musculoskeletal pain (IL-8, P=0.008), sleep disorders (IFN-γ, P=0.02), and PMS (IL-8 and TNF-α, P=0.009 and 0.002, respectively) compared to subjects who reported no symptoms. The pro-:anti-inflammatory cytokine ratios showed pro-inflammatory cytokine dominance in subjects with self-reported symptoms, particularly in the groups with deficient levels of vitamin D. However, the multivariate cytokine-pattern analysis was significantly different between PMS groups only. Conclusion These data point to a possible role of pro-inflammatory cytokines as a contributing factor in self-reported symptoms related to musculoskeletal pain, sleep disorders, and PMS.

  8. Antioxidant and immunomodulatory effects of olive leaf extract on serum level of Th17 related cytokines

    2015-12-01

    Full Text Available Background: Olive has a protective effect against chronic inflammatory conditions. However, it is not clear weather this effect is due to its immunomodulatory or antioxidant property. The aim of this study was to investigate the effect of olive leaf extract on serum levels of Th-17 related cytokines and its antioxidant properties. Materials and Methods: 40 male rats divided into 5 groups, and were treated by placebo (Control group, vitamin C (as a known and potent antioxidant and different doses of olive leaf extract. Four test groups, received vitamin C 10 mg/kg and olive leaf extract which contained 5, 10 and 15 mg/kg Oleuropein. All treatments were applied for 10 consecutive days orally via gavage. After this period, cardiac puncture was performed to retrieve blood from animals in order to determine interleukin 17, 23 and TGFβ levels in their serum by ELISA method. Glutathione peroxidase (GPx, Superoxide dismutase (SOD, Catalase (CAT activities and thiobarbituric acid reactive substances (TBARS, as a lipid peroxidation marker were assayed in right brain hemisphere of treated animals. Results: TBARS increased significantly in control group when compared to the other groups (p0.05, TGFβ concentration was significantly lower in animals which treated by 5 and 15 mg/kg of Oleuropein. Conclusion: Olive leaf extract, which contains Oleuropein, had a significant antioxidant effect on the brain of studied animals, while it was not able to change the Th-17 cell-related cytokines (Except TGFβ significantly. Therefore, it could conclude that the protective role of olive against chronic degenerative diseases is related to its antioxidant properties rather than its effects on pathogenic cytokine profile of Th17 cells.

    Full Text Available The aim of the present study was to examine serum cytokines and nitric oxide (NO levels in patients with cystic echinococcosis (CE. 28 patients with CE were studied and all underwent surgery. Serum levels of tumour necrosis factor-alpha (TNF-α, interleukin IL- 1β, receptor of soluble IL-2R (sIL-2R, IL-6, IL-8, nitrate/nitrite, and C-reactive protein (CRP were determined before and after induction of treatment. Data were compared with those obtained from 28 healthy volunteers. IL-6 was elevated in all CE patients (100%. IL-8 was increased in 11/28 (39.3%. Increased levels of IL-2R and TNF-α were found in a limited number of them particularly those showing cysts in the central area of the liver (5/28, 6/28. IL-1β level was not elevated in any patient except in secondary severe CE. CRP and nitrate/nitrite levels were also increased. A positive correlation between CRP and IL-6 (r = 0.74; p < 0.001 was found confirming the link between inflammation due to CE and activation of monocytes. All patients completely recovered and the levels of the studied parameters reverted to normal levels except one patient in whom severe recurrent disease occurred two years after the first operation. These results suggest that there are different immunoregulatory events and cytokines response during CE and may be in part related to slight monocytosis and in part to Th2 activation. IL-6, NO and CRP were unambiguously involved in the host parasite interaction and therefore may be useful markers in monitoring CE management and evaluating surgical stress.

    Full Text Available Although the role of interleukin-2 (IL-2 and interferon gamma (gIFN is still poorly understood in hyperthyroid diseases, it is reasonable to assume that these cytokines may be present at higher levels in Graves' disease (GD than in other primarily non-autoimmune thyroid diseases. In order to look for an easy method to distinguish GD from primarily non-autoimmune causes of hyperthyroidism, we compared 13 healthy individuals with 21 treated and untreated hyperthyroid GD patients and with 19 patients with hyperthyroidism due to other etiologies: 7 cases of multinodular goiter, 5 cases of excessive hormone replacement and 7 cases of amiodarone-associated hyperthyroidism. All patients presented low TSH levels and a dubious clinical thyroid state. We found a good correlation between TSH and serum IL-2 levels (r = 0.56; PgIFN (P<0.01 levels were lower in the hyperthyroid group of patients than in control subjects, suggesting a depressed TH1 pattern in the T-cell subset of hyperthyroid patients. GD had normal IL-2 levels, while patients with other forms of thyrotoxicosis presented decreased IL-2 levels (P<0.05. There was no difference between treated and untreated GD patients. We suggest that the direct measurement of serum IL-2 level may help to confirm hyperthyroidism caused by GD.

    BACKGROUND: It has been demonstrated that there are changes of various cytokines, chemokines and adhesion factors in neonatal hypoxic ischemic encephalopathy (HIE). What are the changes of interleukin-6 and interleukin-18 in serum of HIE neonates.OBJECTIVE: To observe the dynamic changes of interleukin-6 and interleukin-18 in peripheral serum at different time after HIE in neonates, and analyze the possible therapeutic efficacy of early application of NGF.DESIGN: A non-randomized controlled observation synchronically.SETTING: Department of Neonatology, Sun Yat-sen Hospital affiliated to Sun Yat-sen University.PARTICIPANTS: Sixty neonates with HIE were selected from the Department of Neonatology, Sun Yat-sen Hospital affiliated to Sun Yat-sen University from January 2004 to October 2006, including 32 boys and 28 girls, who were all accorded with the diagnostic standards for moderate to severe HIE. The neonates were divided into two groups NGF-treated group (n =30), HIE group (n =30). The HIE neonates in the NGF-treated group were given routine treatment and intramuscular injection of NGF within 24 hours after birth. Those in the HIE group were given routine treatments. Meanwhile, 30 apneic normal neonates (17 boys and 13 girls) at the same period were selected as the control group. The gestational age was 37 - 42 weeks in all the three groups, the body mass at birth was 2 500 - 4 000 g. Informed contents were obtained from the relatives of all the enrolled neonates.METHODS: The HIE neonates in the NGF-treated group were given routine treatment and intramuscular injection of NGF (2 000 U) within 24 hours after birth, once a day, 10 days as a course. Those in the HIE group were given routine treatments. Blood samples (3 mL) were drawn from femoral vein in all the neonates 1, 3 and 7 days after birth. The levels of interleukin-6 and interleukin-18 in serum were detected with enzyme-linked immunoabsorbent assay (ELISA).MAIN OUTCOME MEASURES: Serum levels of interlenkin

    Dental amalgam restorations release mercury and silver which is absorbed and distributed in the body. Animal studies have shown that both elements may interfere with the host by activation of the immune system in genetically susceptible strains at exposure levels relevant to those from dental amalgam restorations. The aim of this study was to test the hypothesis of no change over time in concentrations of a number of immune mediators in serum after removal of all dental amalgam restorations in patients with health complaints attributed to their amalgam restorations and compare with a healthy reference group. Twenty patients previously examined at a specialty unit for health complaints attributed to dental materials were included in a clinical trial and had all amalgam restorations replaced with other dental restorative materials. Serum samples were collected before amalgam removal and 3 and 12 months after the removal was finished. Twenty blood donors matched for age and gender were used as comparison group. A fluorescent bead-based (Luminex) immunoassay kit was used to measure cytokines, chemokines and growth factors in serum. At baseline, the patient group had slightly higher values for GM-CSF, IL-6, IL-2R, IFN-alpha, IL-7, and IL-12p40/p70 compared with the reference group. After amalgam removal a decrease towards the median value of the reference group was found for GM-CSF, IL-8, and IL-7. In conclusion, removal of all dental amalgam restorations and replacement with other dental restorative materials was associated with decreased concentrations of Th1-type proinflammatory markers in serum.

    Although Nucleos(t)ide analogue therapy is thought to suppress chronic hepatitis B(CHB) via regulation of inflammatory cytokines/chemokines, the mechanism is still unclear. In this study, serum cytokine/chemokine levels were measured in CHB patients treated with entecavir, and the association with antiviral response was analyzed. Seventy-eight Japanese patients with CHB were enrolled, and serum cytokine/chemokine levels were measured at baseline and at 12, 24, and 48 weeks of entecavir treatment using the MULTIPLEX kit. Antiviral response to entecavir treatment was significantly associated with HBsAg titer and serum interferon-gamma-inducible protein 10(IP-10) level (12w) (P=0.0002; OR=0.020 [0.002-0.156], P=0.003; OR=0.042 [0.005-0.336], respectively). HBe-positive patients whose serum macrophage-derived chemokine (MDC) level was lower (<582.83 pg/ml) and IP-10 level was higher (1323.13 pg/ml≤) achieved HBeAg loss earlier than remained HBeAg-positive patients (P=0.044). HBsAg reduction by entecavir treatment was significantly associated with higher initial tumor necrosis factor alpha(TNFα) level (15.20 pg/ml≤) and higher ALT level (73 IU/L≤) (P=0.009; OR=18.460 [2.044-166.709], P=0.022; OR=7.709 [1.341-44.327], respectively). Results of the present study indicate that changes in cytokine/chemokine levels following entecavir therapy are associated with response to antiviral therapy in CHB patients. Monitoring of serum cytokine/chemokine levels could be useful for predicting reduction of HBV DNA and HBsAg and HBe seroconversion.

    Full Text Available Abstract. The serum levels of cytokines and total IgE in 113 children with salmonellosis were tested in ELISA. It was established, that severe course of infection in chidren up to 4 years of age is associated with low level of IL-10, and after 4 years of age with IFNγ deficit. Low level of total IgE is the marker of severe salmonellosis too, particularly in children up to 4 years of age.

    The IL-6 -174G/C (rs1800795), TNF-α -308G/A (rs1800629) and -238G/A (rs361525) and SDF-1 801G/A (rs1801157) are well characterized SNPs which have previously been linked to various diabetic complications. However, the involvement of these SNPs in DFU remains poorly studied. In the present study we looked at the association of these SNPs with DFU (disease phenotype) and correlated it with the serum levels of cytokines (intermediate phenotype) along with other clinical risk factors of DFU (adiponectin, leptin and hsCRP). Genotyping was carried out in Normal glucose tolerance ((NGT)/Control=106), T2DM without DFU (T2DM=139), T2DM with neuropathy (DFU-DN=191) and T2DM with PVD (DFU-PVD=79) subjects by PCR-RFLP and the serum cytokine levels were determined by ELISA. IL-6 -176 "C" allele conferred significant protection against T2DM but not against DFU. TNF-α -308 "A" allele (but not -238 SNP) conferred significant susceptibility towards both T2DM and DFU-DN. The SDF-1 "A" allele conferred significant protection against both DM and DFU-DN but not against DFU-PVD. Further, these alleles were shown to influence the serum cytokine/chemokine levels under diabetic conditions. Thus SNPs in cytokine/chemokine genes serve as valuable biomarkers for DFU.

    Objective:To investigate variations of Th1/Th2 cytokine levels, as well as their correlation with eczema development and clinical manifestation in aged patients.Methods: A total of 92 patients (above 60 years old) with eczema diagnosed by the outpatient department of dermatology and venerology of our hospital were included as the eczema group, while 60 aged patients without eczema as the healthy group. Patients' serum levels of Th1/Th2 cytokines were examined for inter-group comparison and stratified analysis as per clinical manifestation. Results:Serum levels of interleukin (IL)-2, IL-4, IL-10, IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ were all significantly higher in patients of the eczema group than the healthy group. Acute stage levels of IL-2, IL-4, IL-10 and IFN-γ were significantly higher in patients of the eczema group than the healthy group. There was no significant difference in the levels of IL-12 and TNF-α between patients of the acute stage and those of the chronic stage. And no significant difference existed in the levels of IL-2, IL-4, IL-10, IL-12, TNF-α and IFN-γ between generalized and localized eczema patients.Conclusion:Compared with the healthy population, Th1/Th2 cytokine levels are significantly different in eczema patients, especially those in the acute stage.

    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 Goeckerman regimen (GR) involves the dermal application of a crude coal tar (polycyclic aromatic hydrocarbon, PAH) and exposure to ultraviolet (UV) radiation. Both PAH and UV radiation exhibit immunosuppressive activity. This study describes the changes in the serum levels of the pro-inflammatory cytokine interleukin-12 (IL-12) and the anti-inflammatory cytokine IL-10 in patients with psoriasis (n = 55) treated with GR. The serum levels of IL-12 and IL-10 were compared before and after GR. In addition, the IL-12 and IL-10 levels in psoriatic patients were compared with those in a control group of healthy blood donors (n = 47). The Psoriasis Area and Severity Index (PASI) was used to evaluate the efficacy of GR. When compared with the control group, both IL-12 and IL-10 were significantly higher in psoriatic patients in all cases (P < 0.001). When compared before and after GR, the IL-12 and IL-10 levels (P < 0.01) and PASI value (P < 0.001) were significantly lower after GR. The decrease in the serum level of IL-12 and IL-10 after GR was related to the entry value before GR (IL-12, r = 0.60, P < 0.001; IL-10, r = 0.36, P < 0.01). There was a significant correlation between the IL-10 level before GR and the PASI value after GR = -0.39; P < 0.01). The results indicate a strong pro-inflammatory effect of IL-12 in the immunopathogenesis of psoriasis, and confirm the immunosuppressive and anti-inflammatory effect of GR. IL-10 seems to be a promising individual marker for a positive effect of GR therapy.

    Full Text Available Disturbance of the cytokine equilibrium has been accused for many pathological disorders. Microbial infections, autoimmune diseases, graft rejection have been correlated to over- or under-production of specific cytokines which are produced as responder molecules to the various immune stimuli. The sole naturally occurring immune reaction in the organism is developed during the gestational period where, despite the presence of a semi-allogeneic graft, maternal immunoreactivity is driven to support fetal growth. The successful embryo development has been attributed to the important intervention of cytokines where some have been characterized as indispensable and others deleterious to fetal growth. However, the physiological levels of many factors during the gestational process have not been determined. Thus, in the present study we have measured and established the values of IL-1α, IL-2, IL-3, IL-4, IL-6, IL-10, IL-12, GM-CSF, TNF- α and IFN-γ during all phases of human pregnancy (first, second and third trimester of pregnancy, labour, abortions of the first trimester as well as in the non-pregnant control state. This is an attempt to assess serum protein concentrations and present the physiological levels of these cytokines at certain time intervals providing thus a diagnostic advantage in pregnancy cases where the mother cannot immunologically support the fetus. Exploitation of this knowledge and further research may be useful for therapeutic interventions in the future.

    The release of proangiogenic cytokines into the circulation after stem cell (SC) therapy and compensatory increase of angiogenesis inhibitors may reflect local vasculogenesis but also can increase the risk of side effects. The aim of our study was to evaluate serum levels of angiogenic cytokines with regard to the assessment of local and systemic vasculogenesis in diabetic patients with no-option critical limb ischemia (NO-CLI). Twenty-five diabetic patients with NO-CLI treated with SCs isolated from bone marrow or stimulated peripheral blood were included in the study. Serum levels of proangiogenic cytokines (VEGF, bFGF, Ang-1, PDGF-AA, and PDGF-BB) and an antiangiogenic cytokine (endostatin) were assessed 6 months after cell treatment, compared to baseline values, and correlated with the number of injected CD34(+) cells. The clinical effect of SC therapy (assessed by changes in TcPO2) and potential systemic vasculogenesis (assessed by eye fundus examination) were evaluated after 6 months. Serum levels of angiogenic inhibitor endostatin increased significantly after 1 and 3 months (p = 0.0003), but no significant increase in serum levels of proangiogenic cytokines was observed. A significant correlation between number of injected CD34(+) cells and serum levels of endostatin was observed (r = 0.41, p cytokines did not correlate with CD34(+) cells. No correlation between increase in TcPO2 after treatment and serum levels of any of the angiogenic cytokines were seen, and no signs of systemic vasculogenesis in the retina were observed after 6 months. Despite the significant increase in the levels of the angiogenic inhibitor endostatin following SC treatment, there was no risk of systemic vasculogenesis after SC therapy as documented by serum levels of proangiogenic cytokines or changes in the retina.

    Objective: To investigate the intervention effect of Jianxin Decoction (健心汤, JXD) on the cytokine level in serum of patients with congestive heart failure (CHF). Methods: Sixty-six patients with CHF were randomly divided into the control group (n=33) and the trial group (n=33). The control group received conventional treatment, and the trial group was treated with conventional therapy plus JXD for 4weeks. Before and after treatment, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and nitrogen monoxide (NO) in serum and cardiac function were determined. Results: After treatment, the levels of TNF-α,IL-6 and NO were significantly lower than those before treatment (P<0.05, or P<0. 01) in the two groups,and the lowering degree of the indices in the trial group was more significantly reduced than that in the control group (P<0. 05). And cardiac functions in both groups were improved significantly (P < 0.05, or P <0.01). Conclusion: JXD could prevent and reverse ventricular remodeling so as to ameliorate cardiac function through regulating the levels of cytokines.

    The increase in the inflammatory process is one of the main factors that contribute to aging. The aim of this study was to investigate the effects of a diphenyl diselenide (PhSe)2-supplemented diet (1p.p.m., 4weeks) and swimming exercise (3% of body weight, 20min per day, 4weeks) on the serum levels of cytokines in Wistar rats of different ages. The results demonstrated an increase in the levels of pro-inflammatory cytokines (IL-1β, IL-6, TNFα and INFγ) and a decrease in the levels of IL-10, an anti-inflammatory cytokine, with age. In middle-age rats, the swimming exercise and (PhSe)2-supplemented diet decreased serum levels of pro-inflammatory cytokines and increased the levels of IL-10. By contrast, in old rats the swimming exercise protocol increased the serum levels of pro-inflammatory cytokines and decreased the levels IL-10. Diet supplemented with (PhSe)2 did not alter the serum levels of cytokines in old rats. Middle-age and old rats subjected to swimming exercise and supplemented with (PhSe)2 in the diet had a decrease in the serum levels of pro-inflammatory cytokines and an increase in the levels of IL-10. This study demonstrated that swimming exercise and (PhSe)2-supplemented diet affect the serum levels of pro- and anti-inflammatory cytokines differently depending on the age of rats. (PhSe)2 supplemented in the diet had an anti-inflammatory effect, similar to that of induced by swimming exercise, in middle-age rats and reversed the pro-inflammatory effects of swimming exercise in old rats.

    The objective of the present work was to study the influence of allelic variant associations of 1-beta interleukin (C3953T, &511C, T31C), interleukin-6 (C174G), and tumour necrosis factor-alpha (G308A) gene polymorphisms on the serum cytokine level in the patients presenting with chronic suppurative otitis media. A total of 299 patients at the age varying from 16 to 55 years with this condition divided into three groups were examined. Group 1 was comprised of 146 patients suffering from the tubotympanic form of chronic suppurative otitis media (CSOM). Group 2 was composed of 153 patients with epitympanic antral form of this condition. The control group included 183 subjects who have never suffered pathological changes in the middle ear. Human genomic DNA was analyzed with the use of the polymerase chain reaction (PCR). The serum cytokine levels were measured by the solid-state enzyme immunoassay in the beginning and at the end of the treatment period. The study has demonstrated that 56.2% of the healthy residents of the trans-Baikal region had the C/T Il-1b (C3953T) genotype. 79.1% of the patients presenting with the carious carious-destructive form of chronic suppurative otitis media were the heterozygous carriers of the T511C gene of 1-beta interleukin and had the maximally high concentrations of this interleukin in the blood serum. A rise in the production of the pro-inflammatory mediator (IL-6) was found to be related to the severity of the inflammatory process in the middle ear. The TNF-alpha content in the patients with CSOM during the active period of the disease proved to increase by a factor of 6 in comparison with that in the subjects of the control group irrespective of the type of mutation.

    Aging and obesity exert important effects on disease. Differentiating these effects is difficult, however, because weight gain often accompanies aging. Here, we used a nested design of aged, calorically restricted, and refed rats to measure changes in brain and blood levels of cytokines and gastrointestinal hormones, brain amyloid precursor protein levels, and brain and body weights. By comparing groups and using path analysis, we found divergent influences of chronological aging versus body weight, our main findings being (i) changes in whole brain weight and serum macrophage colony-stimulating factor levels correlated better with body weight than with chronological aging, (ii) a decrease in brain cytokines and brain plasminogen activator inhibitor levels correlated better with chronological aging than with body weight, (iii) serum erythropoietin levels were influenced by both body weight and aging, (iv) serum plasminogen activator inhibitor, serum cytokines, and brain tumor necrosis factor were not influenced by aging or body weight, and (v) brain amyloid precursor protein more closely related to body weight and serum levels of gastrointestinal hormones than to brain weight, chronological aging, or cytokines. These findings show that although aging and body weight interact, their influences are distinct not only among various cytokines and hormones but also between the central nervous system and the peripheral tissue compartments.

    Objective: To identify the correlation between serum inflammatory cytokine levels including high sensitive C reactive protein (hs-CRP) and lipoprotein associated phospholipase (Lp-PLA2) and the fibrous cap thickness of fibrofatty plaque in coronary culprit lesions. Methods: Clinical data of 117 patients with selective coronary artery angiography diagnosed coronary artery disease admitted to our hospital from January 2015 to January 2016 were retrospective analyzed. According to type of coronary disease, patients were divided into 3 subgroups: SAP group (containing 47 stable angina patients), UAP group (containing 52 unstable angina patients), and NSTEMI group(containing 18 acute non ST segment elevation myocardial infarction patients). Serum hs-CRP and Lp-PLA2 levels were measured before subsequent procedures. The characteristics of the culprit lesions were detected by optical coherence tomogarpgy(OCT) before interventional treatment, and the correlation between hs-CRP and Lp-PLA2 and the fibrous cap thickness of fibrofatty plaque in coronary culprit lesions were analyzed. Results: (1) The serum levels of hs-CRP (2.13(1.04, 4.75)μg/L vs. 1.02(0.60, 1.29)μg/L and 1.30(1.03, 1.96)μg/L, all Pcap thickness of fibrofatty plaque in coronary culprit lesions were smaller in NSTEMI group and UAP group than in SAP group(50(50, 60)μm and 60(50, 90)μm vs. 130(80, 190)μm, all P0.05). Proportion of thin-cap fibroatheroma plaque(82.35%(14/18) vs. 19.15%(9/47) and 63.46%(33/52), all P0.05). (3) Pearson correlation analysis showed that serum levels of hs-CRP(r=-0.233, Pcap thickness of fibrofatty plaques. Spearman correlation analysis showed that serum levels of hs-CRP were positively correlated with plaque rupture(r=0.409, Pcap fibroatheroma plaque(OR=1.017, Pcap fibroatheroma plaque, plaque rupture and thrombosis was significantly higher in the NSTEMI patients, while the prevalence of calcification in plaque is more often in SAP patients.

    This study investigated some immunological features by experimental periodontitis (EP) and rheumatoid arthritis (RA) disease interact in destructive processes in arthritic rats. Rats were assigned to the following groups: EP +RA; RA; EP; and Negative Control. RA was induced by immunizations with type-II collagen and a local immunization with Complete Freund’s adjuvant in the paw. Periodontitis was induced by ligating the right first molars. The serum level of rheumatoid factor (RF) and anti-citrullinated protein antibody (ACCPA) were measured before the induction of EP (T1) and at 28 days after (T2) by ELISA assay. ACCPA levels were also measured in the gingival tissue at T2. The specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for the quantification of interleukin IL-1β, IL-4, IL-6, IL-17 and TNF-α using a Luminex/MAGpix assay. Paw edema was analyzed using a plethysmometer. Periodontitis increased the RF and ACCPA levels in the serum and in the gingival tissue, respectively. Besides, the level of paw swelling was increased by EP and remained in progress until the end of the experiment, when EP was associated with RA. Greater values of IL-17 were observed only when RA was present, in spite of PE. It can be concluded that periodontitis increases rheumatic factor serum levels and citrullinated proteins level in gingival tissues and alter cytokine balance in arthritic rats; at the same time, arthritis increases periodontal destruction, confirming the bidirectional interaction between diseases.

    Sex hormones modulate the action of both cytokines and the renin-angiotensin system. However, the effects of angiotensin I-converting enzyme (ACE) on the proinflammatory and anti-inflammatory cytokine levels in male and female spontaneously hypertensive rats (SHR) are unclear. We determined the relationship between ACE activity, cytokine levels and sex differences in SHR. Female (F) and male (M) SHR were divided into 4 experimental groups each (n = 7): sham + vehicle (SV), sham + enalapril (10 mg/kg body weight by gavage), castrated + vehicle, and castrated + enalapril. Treatment began 21 days after castration and continued for 30 days. Serum cytokine levels (ELISA) and ACE activity (fluorimetry) were measured. Male rats exhibited a higher serum ACE activity than female rats. Castration reduced serum ACE in males but did not affect it in females. Enalapril reduced serum ACE in all groups. IL-10 (FSV = 16.4 ± 1.1 pg/mL; MSV = 12.8 ± 1.2 pg/mL), TNF-α (FSV = 16.6 ± 1.2 pg/mL; MSV = 12.8 ± 1 pg/mL) and IL-6 (FSV = 10.3 ± 0.2 pg/mL; MSV = 7.2 ± 0.2 pg/mL) levels were higher in females than in males. Ovariectomy reduced all cytokine levels and orchiectomy reduced IL-6 but increased IL-10 concentrations in males. Castration eliminated the differences in all inflammatory cytokine levels (IL-6 and TNF-α) between males and females. Enalapril increased IL-10 in all groups and reduced IL-6 in SV rats. In conclusion, serum ACE inhibition by enalapril eliminated the sexual dimorphisms of cytokine levels in SV animals, which suggests that enalapril exerts systemic anti-inflammatory and anti-hypertensive effects.

    Mercury is an immunotoxic substance that has been shown to induce autoimmune disease in rodent models, characterized by lymphoproliferation, overproduction of immunoglobulin (IgG and IgE), and high circulating levels of auto-antibodies directed at antigens located in the nucleus (antinuclear auto-antibodies, or ANA) or the nucleolus (antinucleolar auto-antibodies, or ANoA). We have reported elevated levels of ANA and ANoA in human populations exposed to mercury in artisanal gold mining, though other confounding variables that may also modulate ANA/ANoA levels were not well controlled. The goal of this study is to specifically test whether occupational and environmental conditions (other than mercury exposure) that are associated with artisanal gold mining affect the prevalence of markers of autoimmune dysfunction. We measured ANA, ANoA, and cytokine concentrations in serum and compared results from mercury-exposed artisanal gold miners to those from diamond and emerald miners working under similar conditions and with similar socio-economic status and risks of infectious disease. Mercury-exposed gold miners had higher prevalence of detectable ANA and ANoA and higher titers of ANA and ANoA as compared to diamond and emerald miners with no occupational mercury exposure. Also, mercury-exposed gold miners with detectable ANA or ANoA in serum had significantly higher concentrations of pro-inflammatory cytokines IL-1beta, TNF-alpha, and IFN-gamma in serum as compared to the diamond and emerald miners. This study provides further evidence that mercury exposure may lead to autoimmune dysfunction and systemic inflammation in affected populations.

    AIM: To evaluate plasma levels of nitrite/nitrate (NOx),soluble Fas (sFas) antigen, tumor necrosis factor alpha(TNF-α) and interleukin-6 (TL-6) in patients with compensated and acute decompensated cirrhosis and to evaluate mediators causing acute decompensation in liver cirrhosis.METHODS: This prospective study was conducted in the medical intensive care unit of an academic tertiary center. Fifty-five patients with acute decompensation (gastrointestinal hemorrhage, encephalopathy, hydropic decompensation) and twenty-five patients with compensated liver cirrhosis were included. Blood samples were taken for analyses of sfas, Nox, TL-6, TNF-α. Liver enzymes and kidney functions were also tested.RESULTS: In patients with acute decompensation, plasma sfas levels were higher than in non-decompensated patients (15305±4646 vs 12458 ± 4322 pg/mL, P <0.05). This was also true for the subgroup of patients with alcoholic liver cirrhosis (P < 0.05). The other mediators were not different and none of the parameters predicted survival, except for ALT (alanine-aminotransferase). In patients with portal-hypertension-induced acute hemorrhage, NOx levels were significantly lower than in patients with other forms of decompensation (70.8 ±48.3 vs 112.9 ± 74.9 pg/mL, P < 0.05). When NOx levels were normalized to creatinine levels, the difference disappeared. IL-6, TNF-α and sfas were not different between bleeders and non-bleeders. In decompensated patients sfas, IL-6 and NOx levels correlated positively with creatinine levels, while IL-6 levels were dependent on Child class.CONCLUSION: In acute decompensated cirrhotic patients sFas is increased, suggesting a role of apoptosis in this process and patients with acute bleeding have lower NOx levels. However, in this acute complex clinical situation, kidney function seems to have a predominant influence on mediator levels.

    Inflammatory markers such as interleukin (IL)-6 and tumour necrosis factor-alpha (TNF-α) are elevated in dialysis patients and can predict cardiovascular events and all-cause mortality. Endotoxin is an important source and also another marker of inflammation in patients with chronic kidney disease. The aim of this study was to evaluate the impact of oral probiotics on serum levels of endotoxemia and cytokines in peritoneal dialysis (PD) patients. The decline of residual renal function, peritonitis episodes, and cardiovascular events were also recorded. From July 2011 to June 2012, a randomised, double-blind, placebo-controlled trial was conducted in PD patients. The intervention group received one capsule of probiotics containing 10(9) cfu Bifobacterium bifidum A218, 10(9) cfu Bifidobacterium catenulatum A302, 10(9) cfu Bifidobacterium longum A101, and 10(9) cfu Lactobacillus plantarum A87 daily for six months, while the placebo group received similar capsules containing maltodextrin for the same duration. Levels of serum TNF-α, interferon gamma, IL-5, IL-6, IL-10, IL-17, and endotoxin were measured before and six months after intervention. 39 patients completed the study (21 in the probiotics group and 18 in the placebo group). In patients receiving probiotics, levels of serum TNF-α, IL-5, IL-6, and endotoxin significantly decreased after six months of treatment, while levels of serum IL-10 significantly increased. In contrast, there were no significant changes in levels of serum cytokines and endotoxin in the placebo group after six months. In addition, the residual renal function was preserved in patients receiving probiotics. In conclusion, probiotics could significantly reduce the serum levels of endotoxin, pro-inflammatory cytokines (TNF-α and IL-6), IL-5, increase the serum levels of anti-inflammatory cytokine (IL-10), and preserve residual renal function in PD patients.

    This study aimed to investigate the potential beneficial effects of the montelukast (ML) on oxidative stress and histological alterations in liver tissues and cytokine levels in rats intoxicated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Rats were divided randomly into four equal groups (control, TCDD, ML, TCDD + ML). TCDD were administered by gavages dissolved in corn oil at the doses of 2 µg/kg/week, and ML was given intraperitoneally at the dose of 10 mg/kg/day. Oxidative status, histological alterations, and cytokine levels were analyzed on day 60. The results showed that although TCDD induced oxidative stress via significant increase in formation of thiobarbituric acid reactive substance, it caused a significant decline in glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) levels in liver. Besides, TCDD led to significant histopathological damage in liver and serum cytokine levels alterations (increase in tumor necrosis factor α and interleukin 1β levels). In contrast, ML treatment reversed oxidative effects of TCDD by increasing the levels of GSH, CAT, and SOD and decreasing the formation of TBARS. Also, it can normalize the levels of histological and cytokine alterations induced by TCDD. In conclusion, it was determined that TCDD exposure caused adverse effects on cytokine levels, histological alterations, and oxidative stress in rats. However, ML treatment partially eliminated toxic effects of TCDD. Thus, it was judged that coadministration of ML with TCDD may be useful to attenuate the negative effects of TCDD. © The Author(s) 2013.

    The aim of this study was to investigate whether lower serum vitamin D metabolite levels were associated with altered cytokine/chemokine and metabolic hormone levels in three different hypertensive disorders in pregnancy (HDP). Healthy pregnancy (n = 30) and hypertensive disorders in pregnancy (HDP) (n = 30), i.e., gestational hypertension (GH), preeclampsia (PE), and eclampsia (EC) subjects were enrolled. Vitamin D metabolites were measured by UPLC/APCI/HRMS method. Circulatory 27 cytokines/chemokines and 10 metabolic hormones were measured. Significantly decreased 25(OH)D and 1,25(OH)2D levels were observed in HDP. The levels of 25(OH)D were significantly lower in PE and EC, whereas the serum levels of 1,25(OH)2D significantly decreased only in EC subjects. Serum 25(OH)D and 1,25(OH)2D levels were negatively correlated with systolic- and diastolic blood pressure, creatinine, and uric acid levels. Serum interleukin (IL)-6 and IL-13 decreased, and GIP levels were increased in gestational hypertensive subjects. Platelet-derived growth factor-BB and IL-8 levels were increased and macrophage inflammatory protein-1beta levels were decreased in EC subjects. IL-8 and IL-10 increased, and rantes and GIP levels decreased in the EC group as compared with the GH group. Multivariate logistic regression analysis showed that eotaxin, monocyte chemotactic protein-1, 25(OH)D, and 1,25(OH)2D were predictors of HDP. Our analyses suggest that lower vitamin D metabolites are associated with altered cytokines/chemokines and metabolic hormones in HDP.

    Objective:To explore the effect of tiotropium bromide combined with montelukast on COPD patients’ blood rheology, pulmonary function and serum cytokine levels.Methods: A total of 82 COPD patients who were treated in our hospital from June 2015 to January 2016 were divided into control group and observation group randomly by half. 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

    Although French farmers smoke less on average than individuals from the general population, they suffer more from COPD. Exposure to biological and chemical air pollutants in the farm may be the cause of these higher COPD rates. This study investigates the role of bio-contaminants, including the relationship of exposure to volatile organic compounds (VOCs) and fine particulate matter (of diameter of 2.5 µm [PM2.5]) objectively measured in the farm settings (dwellings and workplaces) to serum cytokines involved in COPD, in a sample of 72 farmers from 50 farms in the Auvergne region, France. Mean concentrations of VOCs were highest inside the home, while levels of PM2.5 were highest in workplaces (stables and granaries). After adjusting for confounders, high exposure to PM2.5 was significantly associated with a decreased level of serum cytokines (among others, IL13: β: -0.94, CI: -1.5 to -0.2, P-value =0.004; IL8: β: -0.82, CI: -1.4 to -0.2, P-value =0.005) and high exposure to VOCs according to a VOC global score with a decreased IL13 level (β: -0.5, CI: -0.9 to -0.1, P-value =0.01). Moreover, respiratory symptoms and diseases, including COPD, were associated with a decreased level of serum cytokines significantly in the case of IL5. An alteration of immune response balance in terms of cytokine levels in relation to indoor chemical air pollution exposure may contribute to respiratory health impairment in farmers.

    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.

    Objectives To observe the profile of the serum levels of inflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor (TNF-o) and interleukin-10 (IL-10) and evaluate the effects of angiotensin- converting enzyme inhibitor-Captopril on them in renohypertensive rats. Methods Using reformed two-kidney-one-clip (2K 1C ) method, renal hypertensive rats (RHR) were obtained by ligating abdominal aorta.30 Wistar rats were randomized into three groups:sham-operation group (A)、 model control group ( B ) and captopril group (C). All rats were killed after being given the trial drugs 5 weeks, ELISA assays were used to detect the levels of IL-6 and IL-10, the levels of TNF-alpha were measured with radioimmtmoassays.hypertrophy was aggravated in group B significantly,the ratio of left ventricle and body weight(LV/BW) was 0.00318 ±0.00030 (B)and 0.00256 ±0.00040 (A)respectively(P < 0.001 ), the levels of IL-6 and TNF-o increased significantly (P < 0.001 and P < 0.002respectively), whereas the levels of IL-10 were not compared with group B, the LV/BW was 0.00266 ±0.00018 (C) and 0.00318±0.00030 (B) respectively(P < 0.001), the levels of IL-6 and TNF-α decreased significantly ( P < 0.01), whereas the levels of IL-10were not changed between the two groups (P > 0.05);Conclusions Angiotensin converting enzyme inhibitor-captopril can lower the serum levels of proinflammatory cytokines IL-6 and TNF-α effectively,but can not increase the levels of anti-inflammatory cytokine IL-10, it suggests that captopril may have a feature to prevent or slow the development of hypertensive complications by means of lowering the levels of pro-inflammatory cytokines but not by increasing anti-inflammatory cytokine IL-10.

    Full Text Available We have investigated the serum concentrations of interleukin-6 (IL-6 and two IL-6 family cytokines-oncostatin M (OSM and leukemia inhibitory factor (LIF-in 63 patients with B-cell chronic lymphocytic leukemia (B-CLL and 17 healthy controls using the enzyme-linked immunosorbent assay (ELISA method. Simultaneously, we measured the serum levels of the soluble forms of two subunits of the IL-6 receptor complex-ligand binding glycoprotein 80 (sIL-6R and glycoprotein 130 (sgp130. The cytokines and receptors were evaluated in 25 untreated patients and 38 patients treated with cladribine (2-CdA, as well as in 17 healthy controls. We have correlated the serum levels of these proteins with Rai's clinical stage of the disease, the response to 2-CdA treatment and some hematological parameters. We have also evaluated the correlation of the IL-6 serum level with the concentration of OSM and IL-6 soluble receptors. IL-6 was measurable in 62/63 (98.4%, OSM in 20/25 (80% of untreated and 14/38 (37.8% of the treated patients. sIL-6R and sgp130 were detectable in all 63 patients and LIF in none of the CLL patients. IL-6 serum level in untreated patients was not significantly different as compared to its concentration in the control group (P>0.05. However, in the patients treated with 2-CdA the IL-6 level was significantly lower (P0.05. We have found significant positive correlation between the levels of sIL6R and the lymphocytes count in CLL patients (Ρ=0.423; P<0.001. In addition, sIL-6R and OSM serum concentrations correlated also with CLL Rai stage. In conclusion, the serum level of IL-6, OSM and sIL-6R, but not LIF and sgp130, are useful indicators of CLL activity.

    Interleukin (IL)-17-producing CD4+ T helper (Th17) cells that are known to produce IL-17 have recently been defined as a unique subset of proinflammatory helper cells. Interleukin 17 is an inflammatory cytokine with robust effects on many cells. It can play important roles in the pathogenesis of diverse groups of immune-mediated diseases. In this regard, the present case-control study aimed at determining serum levels of IL-17, IL-6, and transforming growth factor β (TGF-β) in Iranian breast ...

    Dietary phytic acid (PA; myo-inositol [MI] hexaphosphate) is known to inhibit colon carcinogenesis in rodents. Dietary fiber, which is a negative risk factor of colon cancer, improves characteristics of the colonic environment, such as the content of organic acids and microflora. We hypothesized that dietary PA would improve the colonic luminal environment in rats fed a high-fat diet. To test this hypothesis, rats were fed diets containing 30% beef tallow with 2.04% sodium PA, 0.4% MI, or 1.02% sodium PA + 0.2% MI for 3 weeks. Compared with the control diet, the sodium PA diet up-regulated cecal organic acids, including acetate, propionate, and n-butyrate; this effect was especially prominent for cecal butyrate. The sodium PA + MI diet also significantly increased cecal butyrate, although this effect was less pronounced when compared with the sodium PA diet. The cecal ratio of Lactobacillales, cecal and fecal mucins (an index of intestinal barrier function), and fecal β-glucosidase activity were higher in rats fed the sodium PA diet than in those fed the control diet. The sodium PA, MI, and sodium PA + MI diets decreased levels of serum tumor necrosis factor α, which is a proinflammatory cytokine. Another proinflammatory cytokine, serum interleukin-6, was also down-regulated by the sodium PA and sodium PA + MI diets. These data showed that PA may improve the composition of cecal organic acids, microflora, and mucins, and it may decrease the levels of serum proinflammatory cytokines in rats fed a high-fat, mineral-sufficient diet.

    To investigate the effects of L-arginine in different doses on the serum levels of helper T lymphocyte1 (Th1)/Th2 cytokines in severely burned patients. Twenty-nine severely burned patients, with total burn surface area from 50% to 80%TBSA, hospitalized within 20 hours after burn, were randomly divided into control group (10 cases, fed with 5% glucose saline 500 mL), L-arginine 200 mg group (10 cases, fed with 5% glucose saline 500 mL + 200 mg/kg L-arginine), L-arginine 400 mg group (9 cases, fed with 5% glucose saline 500 mL + 400 mg/kg L-arginine). All patients received enteral feeding through nasointestinal tube, started within 22 hours after burn. Fasting venous blood of all patients was harvested on post burn day (PBD) 1 (before enteral feeding), 3, 5, and 7 to determine serum contents of TNF-alpha, IL-1beta, TGF-beta(1) and IL-4 by radio-immunity method and enzyme-linked immunosorbent assay. Serum contents of TNF-alpha and IL-1beta of patients in all groups increased rapidly after burn, and although contents of TNF-alpha (318 +/- 57) ng/mL and IL-1beta (218 +/- 47) pg/mL of patients in L-arginine 200 mg group peaked on PBD 5, they were still significantly lower than those of patients in control group [(389 +/- 34) ng/mL, (272 +/- 40) pg/mL, P 0.05). Serum contents of TGF-beta(1) and IL-4 of patients in each group increased slowly after burn, and content of TGF-beta(1) (110 +/- 16) pg/mL of patients in L-arginine 200 mg group was significantly higher than that of patients in control group [(83 +/- 20) pg/mL, P 0.05). Compared with the dosage of 400 mg/kg L-arginine, the 200 mg/kg dose is more effective in reducing the release of Th1 cytokines and increasing Th2 cytokines production, hence maintaining Th1/Th2 cytokine ratio to produce better immune opsonization during the infection phase of severe burn.

    IL-1β is an endogenous pyrogen that is induced during systemic lipopolysaccharide (LPS)- or IL-1-induced fever. We have examined the fever and cytokine responses following i.p. injection of IL-1 agonists, IL-1α and IL-1β, and compared these with response to LPS (i.p.) in wild-type and IL-1β-deficient mice. The IL-1β deficient mice appear to have elevated body temperature but exhibit a normal circadian temperature cycle. Exogenously injected IL-1β, IL-1α, or LPS induced hyperresponsive fevers in the IL-1β-deficient mice. We also observed phenotypic differences between wild-type and IL-1β-deficient mice in hypothalamic basal mRNA levels for IL-1α and IL-6, but not for IL-1β-converting enzyme or IL-1 receptor type I or type II. The IL-1α mRNA levels were down-regulated, whereas the IL-6 mRNA levels were up-regulated in the hypothalamus of IL-1β-deficient mice as compared with wild-type mice. The IL-1β-deficient mice also responded to LPS challenge with significantly higher serum corticosterone and with lower serum tumor necrosis factor type α levels than the wild-type mice. The data suggest that, in the redundant cascade of proinflammatory cytokines, IL-1β plays an important but not obligatory role in fever induction by LPS or IL-1α, as well as in the induction of serum tumor necrosis factor type α and corticosterone responses either by LPS or by IL-1α or IL-1β.

    Growing evidence shows interrelations of psychological factors, neurological and immunological processes. Therefore, constructs like a balance of activities, the so called "occupational balance", could also have biological correlates. The aim of this study was to investigate potential associations between occupational balance, functioning, cytokines and C-reactive protein (CRP) in patients suffering from a chronic inflammatory disease like rheumatoid arthritis (RA) and healthy people. Moreover, we wanted to explore potential differences in gender and employment status. A descriptive study in patients with RA and healthy people was conducted using the Occupational Balance-Questionnaire (OB-Quest) and the Short-Form 36 Health Survey (SF-36). Serum levels of cytokines, such as interleukin 6 (IL-6) and 8 (IL-8), interferon alpha (INFα), tumour necrosis factor alpha (TNFα), rheumatoid factor (RF) and of CRP were measured. Descriptive statistics, as well as Mann-Whitney U tests and Spearmen's rank correlation coefficients (rs) were calculated. One-hundred-thirty-two patients with RA and 76 healthy people participated. Occupational balance was associated with functioning, cytokines and CRP. The strongest associations were identified in the unemployed healthy-people sample with cytokines and CRP being within the normal range. For example, the OB-Quest item challenging activities was associated with IL-8 (rs=-0.63, p=0.04) and the SF-36 sub-scale bodily pain was associated with IFNα (rs=-0.69, p=0.02). The items rest and sleep (rs=-0.71, p=0.01) and variety of different activities (rs=-0.74, psocial functioning. Employed and unemployed people differed in their age and CRP levels. Additionally, gender differences were found in two OB-Quest items in that fewer women were able to adapt their activities to changing living conditions and fewer men were overstressed. In conclusion, we found preliminary biological evidence for the link between occupation and health in that the

    The present study compares the serum cytokine levels between adolescent depression patients and healthy controls and assesses correlation between depression, anxiety scores and serum levels of eight cytokines. Study also checked the variation in serum levels with medication status (medication free/naïve vs. patients on medication). Following clinical and psychometric assessment of 77 adolescent (aged 13-18 years) depression patients (49 males and 28 females; 56 medication free/naïve) and 54 healthy controls (25 males, 29 females), eight cytokines (IL-1β, IL-2, IL-6, IL-10, TNF-α, IFN-γ, TGF-β1 and IL-17A {denoted IL-17 throughout}) were measured in serum using ELISA. Depressed adolescents had significantly high levels of IL-2 (pcytokine (IL-6) in patients. Anxiety scores showed positive correlation (only in female patients) with IL-1β, IL-10 and negative correlation with TGF-β1 and IL-17. The gender effect in relationship between anxiety and cytokines was not straightforward. On comparing study groups on the medication/naïve status, IL-2 and TGF-β1 showed significant difference between the groups (pcytokines with a gender bias for females. Anxiety scores correlated negatively with TGF-β1 and IL-17.

    Hypertriglyceridemia is an established risk factor for coronary-heart-disease. Inflammatory cytokines are known to be important mediators of atherogenesis; however, the relationship between the concentrations of specific inflammatory cytokines and the presence of hypertriglyceridemia has not been well established. The purpose of this study was to investigate the relationship between the serum levels of several pro- and anti-inflammatory cytokines and the presence of hypertriglyceridemia. Four hundred and eighty-four subjects with/without established hypertriglyceridemia were recruited. Anthropometric parameters and biochemical analysis (including a full fasting lipid profile) were determined. The serum levels of several cytokines and growth factors including IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, MCP-1, IFN-γ, EGF, and VEGF were measured followed by univariate and multivariate analyses. Individuals with hypertriglyceridemia had a significantly higher body mass index, total-cholesterol and triglyceride, compared to the group without hypertriglyceridemia. Serum levels of MCP-1, TNF-α and IL-8 were significantly higher in subjects with hypertriglyceridemia [e.g., IL-8 from 7.8ng/L (95% CI: 4.6-18.9) versus 5.7ng/L (95% CI: 3.6-11.9), Phypertriglyceridemia. Subjects with serum triglycerides of ≥2.25mmol/L had an altered cytokine-profile, particularly with respect to serum IL-8, MCP-1 and TNF-α, which might partially account for its adverse clinical-consequences. Further-investigations in a large multi-center setting are warranted to unravel the potential functional-importance of these cytokines in individuals with hypertriglyceridemia.

    Periodontitis is a chronic inflammatory disease of tooth supporting tissues resulting in periodontal tissue destruction, which may ultimately lead to tooth loss. The disease is characterized by continuous leukocyte infiltration, likely mediated by local chemokine production but the pathogenic mechanisms are not fully elucidated. There are no reliable serologic biomarkers for the diagnosis of periodontitis, which is today based solely on the degree of local tissue destruction, and there is no available biological treatment tool. Prompted by the increasing interest in periodontitis and systemic inflammatory mediators we mapped serum cytokine and chemokine levels from periodontitis subjects and healthy controls. We used multivariate partial least squares (PLS) modeling and identified monocyte chemoattractant protein-1 (MCP-1) and eotaxin as clearly associated with periodontitis along with C-reactive protein (CRP), years of smoking and age, whereas the number of remaining teeth was associated with being healthy. Moreover, body mass index correlated significantly with serum MCP-1 and CRP, but not with eotaxin. We detected higher MCP-1 protein levels in inflamed gingival connective tissue compared to healthy but the eotaxin levels were undetectable. Primary human gingival fibroblasts displayed strongly increased expression of MCP-1 and eotaxin mRNA and protein when challenged with tumor necrosis factor-α (TNF-α and interleukin-1β (IL-1β), key mediators of periodontal inflammation. We also demonstrated that the upregulated chemokine expression was dependent on the NF-κΒ pathway. In summary, we identify higher levels of CRP, eotaxin and MCP-1 in serum of periodontitis patients. This, together with our finding that both CRP and MCP-1 correlates with BMI points towards an increased systemic inflammatory load in patients with periodontitis and high BMI. Targeting eotaxin and MCP-1 in periodontitis may result in reduced leukocyte infiltration and inflammation in

    Periodontitis is a chronic inflammatory disease of tooth supporting tissues resulting in periodontal tissue destruction, which may ultimately lead to tooth loss. The disease is characterized by continuous leukocyte infiltration, likely mediated by local chemokine production but the pathogenic mechanisms are not fully elucidated. There are no reliable serologic biomarkers for the diagnosis of periodontitis, which is today based solely on the degree of local tissue destruction, and there is no available biological treatment tool. Prompted by the increasing interest in periodontitis and systemic inflammatory mediators we mapped serum cytokine and chemokine levels from periodontitis subjects and healthy controls.

    Aflatoxins are known to produce chronic carcinogenic, mutagenic, and teratogenic effects, as well as acute inflammatory effects, especially in the gastrointestinal tract. The potentials of the flavonoid-rich extract from Chromolena odorata (FCO) and melatonin (a standard anti-oxidant and anti-inflammatory agent) against aflatoxin B1 (AFB1)-induced alterations in pro-inflammatory cytokine levels and morphology of liver and small intestines were evaluated in this study. We utilized Wistar albino rats (200-230 g) randomly divided into five groups made up of group A, control rats; group B, rats given AFB1 (2.5 mg/kg, intraperitoneal) twice on days 5 and 7; rats in groups C, D, and E were treated with melatonin (10 mg/kg, intraperitoneal) or oral doses of FCO1 (50 mg/kg) and FCO2 (100 mg/kg) for 7 days, respectively, along with AFB1 injection on days 5 and 7. Serum levels of interleukin 1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were determined using commercial ELISA kits and histopathological evaluation of the liver, duodenum, and ileum were also carried out. We observed significant elevation (p Melatonin and FCO2 produced considerable protection of hepatic tissues, although melatonin was not quite effective in protecting the intestinal lesions. Our findings suggest a modulation of cytokine expression that may, in part, be responsible for the abilities of C. odorata or melatonin in amelioration of hepatic and intestinal lesions associated with aflatoxin B1 injury.

    Inflammatory bowel disease (IBD) is a chronic and progressive inflammatory condition of the gastrointestinal tract. Although the causative events that lead to the onset of IBD are yet to be fully elucidated, deregulation of immune and inflammatory mechanisms are hypothesized to significantly contribute to this disorder. Since the onset of IBD is often during infancy, in the present study, the serum values of a large panel of cytokines and chemokines in pediatric patients (<18 years; n=26) were compared with age-matched controls (n=37). While elevations in the serum level of several proinflammatory and immune regulating cytokines were confirmed, such as interleukin (IL)-1β, IL-5, IL-7, interferon (IFN)-γ-inducible protein-10, IL-16, cutaneous T-cell-attracting chemokine, leukemia inhibitory factor, monokine induced by γ-IFN, IFN-α2 and IFN-γ, notably decreased levels of IL-2, IL-17 and macrophage inhibitory protein-1β were also observed. Therefore, while a number of proinflammatory cytokines exhibit increased levels in IBD patients, pediatric IBD patients may also exhibit certain aspects of a reduced immunological response.

    Mustard gas, even in low doses, has the ability to inflict damage in multiple organs especially the skin, eyes, as well as the respiratory tract. This damage may cause many complications which persist during the lifespan of exposed subjects. Pro-inflammatory cytokines including TNF, IL-1alpha, IL-1beta and IL-1Ra cause systemic inflammatory reactions and numerous changes including altered cell signaling and migration, changes in cytokine production and fever. The aim of this study was to determine the serum levels of these cytokines in subjects who were exposed to mustard gas 20 years ago in comparison with an unexposed control group. In this historical cohort study 368 sulfur mustard (SM) exposed participants from Sardasht and 126 age-matched unexposed volunteers from Rabat (a nearby town) as controls were chosen by a random systematic sampling. The serum concentrations of IL-1alpha, IL-1beta, IL-1Ra and TNF were measured by a sandwich ELISA technique. Median of the serum levels of cytokines TNF, IL-1alpha, IL-1beta and IL-1Ra in the control group was 23.79, 1.89, 1.91 and 32.9 pg/ml respectively, while in the SM-exposed participants these values were 11.11, 0.81, 1.73 and 26.7 pg/ml respectively. The serum pro-inflammatory cytokine levels were significantly lower in the exposed group than in controls (pcytokines, the strongest being between IL-1beta and TNF (r=0.809 in the control group). The observed down-regulation of pro-inflammatory cytokines should be considered in interpretation of diagnosis and therapeutic measures taken to improve clinical complications.

    Secondary hypoxia is a known contributor to adverse outcomes in patients with traumatic brain injury (TBI). Based on the evidence that hypoxia and TBI in isolation induce neuroinflammation, we investigated whether TBI combined with hypoxia enhances cerebral cytokine production. We also explored whether increased concentrations of injury biomarkers discriminate between hypoxic (Hx) and normoxic (Nx) patients, correlate to worse outcome, and depend on blood-brain barrier (BBB) dysfunction. Forty-two TBI patients with Glasgow Coma Scale ≤8 were recruited. Cerebrospinal fluid (CSF) and serum were collected over 6 days. Patients were divided into Hx (n=22) and Nx (n=20) groups. Eight cytokines were measured in the CSF; albumin, S100, myelin basic protein (MBP) and neuronal specific enolase (NSE) were quantified in serum. CSF/serum albumin quotient was calculated for BBB function. Glasgow Outcome Scale Extended (GOSE) was assessed at 6 months post-TBI. Production of granulocye macrophage-colony stimulating factor (GM-CSF) was higher, and profiles of GM-CSF, interferon (IFN)-γ and, to a lesser extent, tumor necrosis factor (TNF), were prolonged in the CSF of Hx but not Nx patients at 4-5 days post-TBI. Interleukin (IL)-2, IL-4, IL-6, and IL-10 increased similarly in both Hx and Nx groups. S100, MBP, and NSE were significantly higher in Hx patients with unfavorable outcome. Among these three biomarkers, S100 showed the strongest correlations to GOSE after TBI-Hx. Elevated CSF/serum albumin quotients lasted for 5 days post-TBI and displayed similar profiles in Hx and Nx patients. We demonstrate for the first time that post-TBI hypoxia is associated with prolonged neuroinflammation, amplified extravasation of biomarkers, and poor outcome. S100 and MBP could be implemented to track the occurrence of post-TBI hypoxia, and prompt adequate treatment.

    Although French farmers smoke less on average than individuals from the general population, they suffer more from COPD. Exposure to biological and chemical air pollutants in the farm may be the cause of these higher COPD rates. This study investigates the role of bio-contaminants, including the relationship of exposure to volatile organic compounds (VOCs) and fine particulate matter (of diameter of 2.5 µm [PM2.5]) objectively measured in the farm settings (dwellings and workplaces) to serum cytokines involved in COPD, in a sample of 72 farmers from 50 farms in the Auvergne region, France. Mean concentrations of VOCs were highest inside the home, while levels of PM2.5 were highest in workplaces (stables and granaries). After adjusting for confounders, high exposure to PM2.5 was significantly associated with a decreased level of serum cytokines (among others, IL13: β: −0.94, CI: −1.5 to −0.2, P-value =0.004; IL8: β: −0.82, CI: −1.4 to −0.2, P-value =0.005) and high exposure to VOCs according to a VOC global score with a decreased IL13 level (β: −0.5, CI: −0.9 to −0.1, P-value =0.01). Moreover, respiratory symptoms and diseases, including COPD, were associated with a decreased level of serum cytokines significantly in the case of IL5. An alteration of immune response balance in terms of cytokine levels in relation to indoor chemical air pollution exposure may contribute to respiratory health impairment in farmers. PMID:28503065

    To identify serum cytokine networks specific to chronic inflammatory demyelinating polyneuropathy (CIDP), serum samples of two subgroups (18 patients with typical CIDP and 12 patients with multifocal acquired demyelinating sensory and motor neuropathy [MADSAM]) were analyzed with multiplex magnetic bead-based cytokine assay. TNF-α, HGF, MIP-1β and IL-1β levels were significantly higher in total CIDP patients than in normal controls. Of these, HGF levels were elevated in typical CIDP patients, but not in MADSAM patients. Patients with high HGF levels showed good responses to steroid treatment. Different cytokine profiles among the CIDP subtypes presumably reflect differences in pathophysiology.

    It was aimed to evaluate the relationship between proinflammatory cytokine levels and conversion disorder both commonly known as stress regulated. Baseline proinflammatory cytokine levels-[Tumour necrosis factor alpha (TNF-α), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6)]-were evaluated with enzyme-linked immunosorbent assay in 35 conversion disorder patients and 30 healthy controls. Possible changes in proinflammatory cytokine levels were evaluated again, after their acute phase in conversion disorder patients. Statistically significant decreased serum TNF-α levels were obtained in acute phase of conversion disorder. Those levels increased after acute conversion phase. There were no statistically significant difference observed between groups in serum IL-1β and (IL-6) levels. Stress associated with conversion disorder may suppress immune function in acute conversion phase and may have diagnostic and therapeutic value.

    Degenerative joint disease (DJD) is highly prevalent in cats, and pain contributes to morbidity. In humans, alterations of cytokine concentrations have been associated with joint deterioration and pain. Similar changes have not been investigated in cats. Cytokine concentrations can be measured using multiplex technology with small samples of serum or plasma, however, serum and plasma are not interchangeable for most bioassays. Correlations for cytokine concentrations between serum and plasma have not been evaluated in cats. To evaluate the levels of detection and agreement between serum and plasma samples in cats. Paired serum and plasma samples obtained from 38 cats. Blood was collected into anti-coagulant free and EDTA Vacutainer(®) tubes, serum or plasma extracted, and samples frozen at -80°C until testing. Duplicate samples were tested using a 19-plex feline cytokine/chemokine magnetic bead panel. Agreement between serum and plasma for many analytes was high, however correlation coefficients ranged from -0.01 to 0.97. Results from >50% of samples were below the lower limit of quantification for both serum and plasma for nine analytes, and for an additional three analytes for plasma only. While serum and plasma agreement was generally good, detection was improved using serum samples. Copyright © 2016 Elsevier B.V. All rights reserved.

    Recent advances in the identification of susceptibility genes and environmental exposures provide strong support that narcolepsy-cataplexy is an immune-mediated disease. Only few serum cytokine studies with controversial results were performed in narcolepsy and none in the cerebrospinal fluid. We measured a panel of 12 cytokines by a proteomic approach in the serum of 35 patients with narcolepsy-cataplexy compared to 156 healthy controls, and in the cerebrospinal fluid of 34 patients with narcolepsy-cataplexy compared to 17 non-narcoleptic patients; and analyzed the effect of age, duration and severity of disease on the cytokine levels. After multiple adjustments we reported lower serum IL-2, IL-8, TNF-α, MCP-1 and EGF levels, and a tendency for higher IL-4 level in narcolepsy compared to controls. Significant differences were only found for IL-4 in cerebrospinal fluid, being higher in narcolepsy. Positive correlations were found in serum between IL-4, daytime sleepiness, and cataplexy frequency. The expression of some pro-inflammatory cytokines (MCP-1, VEGF, EGF, IL2, IL-1β, IFN-γ) in either serum or CSF was negatively correlated with disease severity and duration. No correlation was found for any specific cytokine in 18 of the patients with narcolepsy with peripheral and central samples collected the same day. Significant decreased pro/anti-inflammatory cytokine profiles were found at peripheral and central levels in narcolepsy, together with a T helper 2/Th1 serum cytokine secretion imbalance. To conclude, we showed some evidence for alterations in the cytokine profile in patients with narcolepsy-cataplexy compared to controls at peripheral and central levels, with the potential role of IL-4 and significant Th1/2 imbalance in the pathophysiology of narcolepsy.

    Full Text Available Ulcerative colitis (UC is associated with increased dietary intake of fat and n-6 polyunsaturated fatty acids (PUFA. Modification of fat metabolism may alter inflammation and disease severity. Our aim was to assess differences in dietary and serum fatty acid levels between control and UC subjects and associations with disease activity and inflammatory cytokines.Dietary histories, serum, and colonic tissue samples were prospectively collected from 137 UC subjects and 38 controls. Both histologic injury and the Mayo Disease Activity Index were assessed. Serum and tissue cytokines were measured by Luminex assay. Serum fatty acids were obtained by gas chromatography.UC subjects had increased total fat and oleic acid (OA intake, but decreased arachidonic acid (AA intake vs controls. In serum, there was less percent saturated fatty acid (SFA and AA, with higher monounsaturated fatty acids (MUFA, linoleic acid, OA, eicosapentaenoic acid (EPA, and docosapentaenoic acid (DPA in UC. Tissue cytokine levels were directly correlated with SFA and inversely correlated with PUFA, EPA, and DPA in UC subjects, but not controls. 5-aminosalicylic acid therapy blunted these associations.In summary, we found differences in serum fatty acids in UC subjects that correlated with pro-inflammatory tissue cytokines. We propose that fatty acids may affect cytokine production and thus be immunomodulatory in UC.

    Interferon (IFN)β treatment is a mainstay of relapsing-remitting multiple sclerosis (RRMS) immunotherapy. Its efficacy is supposedly a consequence of impaired trafficking of inflammatory cells into the central nervous system and modification of the proinflammatory/antiinflammatory cytokine balance....... However, the effects of long-term monotherapy using various IFNβ preparations on cytokine profiles and the relevance of these effects for the therapy outcome have not yet been elucidated....

    BACKGROUND:Hepatic reperfusion injury may cause acute inlfammatory damage, producing signiifcant organ dysfunction, and is an important problem in liver transplantation. This experiment aimed to study early changes of hepatic function after donor liver denervation and Kupffer cell depletion in rat-to-rat liver transplantation and to evaluate the effect of pre-treatment on liver reperfusion injury. METHODS:Donor rats were divided into four groups:control group; group G was pre-treated with gadolinium chloride (G), an inhibitor of Kupffer cells; group H with hexamethonium (H), a sympathetic ganglionic blocking agent; and group HG, with combined H and G pre-treatment. Under the same conditions, serum alanine aminotransferase (ALT), arterial ketone body ratio (AKBR), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and superoxide dismutase (SOD) of recipient rats were assessed at 4, 8, 16 and 24 hours after liver transplantation. Histological studies of the grafts were compared. RESULTS:HG pre-treatment signiifcantly decreased ALT, TNF-α, and IL-6 levels, increased AKBR and SOD levels, and demonstrated less pathological damage at 8, 16 and 24 hours compared with the control group. Similar trends were also found in the other groups (G and H). However, the differences among them were not signiifcant at 4 post-operative hours.CONCLUSIONS:Donor denervation and Kupffer cell depletion had preventive effect on liver reperfusion injury. HG pre-treatment is a feasible and reproducible method to protect grafts from reperfusion injury.

    Full Text Available The overall survival of patients with pancreatic ductal adenocarcinoma is extremely low. Although gemcitabine is the standard used chemotherapy for this disease, clinical outcomes do not reflect significant improvements, not even when combined with adjuvant treatments. There is an urgent need for prognosis markers to be found. The aim of this study was to analyze the potential value of serum cytokines to find a profile that can predict the clinical outcome in patients with pancreatic cancer and to establish a practical prognosis index that significantly predicts patients’ outcomes. We have conducted an extensive analysis of serum prognosis biomarkers using an antibody array comprising 507 human cytokines. Overall survival was estimated using the Kaplan-Meier method. Univariate and multivariate Cox’s proportional hazard models were used to analyze prognosis factors. To determine the extent that survival could be predicted based on this index, we used the leave-one-out cross-validation model. The multivariate model showed a better performance and it could represent a novel panel of serum cytokines that correlates to poor prognosis in pancreatic cancer.

    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. Cytokine profile variations between the patients with mild and severe illness may indicate prognosis and strain virulence, useful in clinical treatment of patients.

    We demonstrated, in a recently published study, far more PPD negative reactivity among patients who had RA (70%) than among controls (30%). To evaluate the hypothesis that different response to PPD in RA patients is associated with different profiles of serum cytokines, we compared the serum levels of IL-2, IL-4, IL-6, IL-10, TNF alpha and IFN gamma from PPD negative and PPD positive RA patients. We also evaluated any correlations between serum cytokines and RA activity. Forty RA patients and 21 controls were enrolled. Those with an induration < 5mm were considered as negative and those with ≥ 5mm as positive PPD. Disease activity was calculated using DAS28. Plasma levels of cytokines were determined using the multiplex BD TM Cytometric Bead Array Kit Assay. Of the RA patients, 27 (67.5%) had negative reaction to PPD and 13 (32.5%) a positive reaction to PPD. There was no statistical difference in sex profile, age or activity index between both negative and positive PPD RA patients. There was no significant difference in all the cytokines measured between PPD positive and PPD negative RA patients. Index activity show a positive correlation with IFN gamma (r = 0.433; p = 0.005) and IL-6 (r = 0.325; p = 0.041) in RA patients. Positive and negative tuberculin RA patients seem to show a similar cytokine serum profile. Copyright © 2006 Elsevier España S.L. Barcelona. Published by Elsevier Espana. All rights reserved.

    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 Allergy is inversely related to glioma risk. To determine whether prediagnostic allergy-related serum proteins are associated with glioma, we conducted a nested case-control study of seven cytokines (IL4, IL13, IL5, IL6, IL10, IFNG, TGFB2, two soluble cytokine receptors (sIL4RA, sIL13RA2 and three allergy-related transcription factors (FOXP3, STAT3, STAT6 using serum specimens from the Janus Serum Bank Cohort in Oslo, Norway. Blood donors subsequently diagnosed with glioma (n = 487 were matched to controls (n = 487 on age and date of blood draw and sex. We first estimated individual effects of the 12 serum proteins and then interactions between IL4 and IL13 and their receptors using conditional logistic regression. We next tested equality of case-control inter-correlations among the 12 serum proteins. We found that TGFB2 is inversely related to glioblastoma (Odds Ratio (OR = 0.87, 95% Confidence Interval (CI = 0.76, 0.98. In addition, ≤ 5 years before diagnosis, we observed associations between IL4 (OR = 0.82, 95% CI = 0.66, 1.01, sIL4RA (OR = 0.80, 95% CI = 0.65, 1.00, their interaction (OR = 1.06, 95% CI = 1.01, 1.12 and glioblastoma. This interaction was apparent > 20 years before diagnosis (IL4-sIL4RA OR = 1.20, 95% CI = 1.05, 1.37. Findings for glioma were similar. Case correlations were different from control correlations stratified on time before diagnosis. Five years or less before diagnosis, correlations among case serum proteins were weaker than were those among controls. Our findings suggest that IL4 and sIL4RA reduce glioma risk long before diagnosis and early gliomagenesis affects circulating immune function proteins.

    Full Text Available Abstract Background Microarray technology may offer a new opportunity to gain insight into disease-specific global protein expression profiles. The present study was performed to apply a serum antibody microarray to screen for differentially regulated cytokines in Parkinson's disease (PD, multiple system atrophy (MSA, progressive supranuclear palsy (PSP and corticobasal syndrome (CBS. Results Serum samples were obtained from patients with clinical diagnoses of PD (n = 117, MSA (n = 31 and PSP/CBS (n = 38 and 99 controls. Cytokine profiles of sera from patients and controls were analyzed with a semiquantitative human antibody array for 174 cytokines and the expression of 12 cytokines was found to be significantly altered. In a next step, results from the microarray experiment were individually validated by different immunoassays. Immunoassay validation confirmed a significant increase of median PDGF-BB levels in patients with PSP/CBS, MSA and PD and a decrease of median prolactin levels in PD. However, neither PDGF-BB nor prolactin were specific biomarkers to discriminate PSP/CBS, MSA, PD and controls. Conclusions In our unbiased cytokine array based screening approach and validation by a different immunoassay only two of 174 cytokines were significantly altered between patients and controls.

    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

    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.

    Full Text Available Introduction: Exercise performed at the hypoxia equivalent of an altitude of 4200 m is associated with elevated inflammatory mediators and changes in the Th1/Th2 response. By contrast, supplementation with carbohydrates has an anti-inflammatory effect when exercise is performed under normoxic conditions. The objective of this study was to evaluate the effect of carbohydrate supplementation on cytokines and cellular damage markers after exercise under hypoxic conditions at a simulated altitude of 4200 m. Methods: Seven adult male volunteers who exercised for 60 min at an intensity of 50% VO2Peak were randomly evaluated under three distinct conditions; normoxia, hypoxia and hypoxia + carbohydrate supplementation. Blood samples were collected at rest, at the end of exercise and after 60 min of recovery. To evaluate hypoxia + carbohydrate supplementation, volunteers received a solution of 6% carbohydrate (maltodextrin or a placebo (strawberry-flavored Crystal Light®; Kraft Foods, Northfield, IL, USA every 20 min during exercise and recovery. Statistical analyses comprised analysis of variance, with a one-way ANOVA followed by the Tukey post hoc test with a significance level of p < 0.05. Results: Under normoxic and hypoxic conditions, there was a significant increase in the concentration of IL-6 after exercise and after recovery compared to at rest (p < 0.05, while in the hypoxia + carbohydrate group, there was a significant increase in the concentration of IL-6 and TNF-α after exercise compared to at rest (p < 0.05. Furthermore, under this condition, TNF-α, IL-2 and the balance of IL-2/IL-4 were increased after recovery compared to at rest (p < 0.05. Conclusion: We conclude that carbohydrate supplementation modified the IL-6 and TNF-α serum concentrations and shifted the IL-2/IL-4 balance towards Th1 in response without glycemic, glutaminemia and cell damage effects.

    Pancreatic ductal adenocarcinoma is a deadly disease because of late diagnosis and chemoresistance. We aimed to find a panel of serum cytokines representing diagnostic and predictive biomarkers for pancreatic cancer. A cytokine antibody array was performed to simultaneously identify 507 cytokines in sera of patients with pancreatic cancer and healthy controls. The nonparametric Mann-Whitney U test was used to pairwise compare the controls, the pretreated patients, and the posttreated patients. Fold changes greater than or equal to 1.5 or less than or equal to 1/1.5 were considered significant. Receiver operating characteristic curves were used to assess the performance of the model. A leave-one-out cross-validation was used for estimating prediction error. Comparing the sera of pretreated patients against the control samples, the cytokines fibroblast growth factor 10 (FGF-10/keratinocyte growth factor-2 (KGF-2), chemokine (C-X-C motif) ligand 11 interferon inducible T cell alpha chemokine (I-TAC)/chemokine [C-X-C motif] ligand 11 (CXCL11), oncostatin M (OSM), osteoactivin/glycoprotein nonmetastatic melanoma protein B, and stem cell factor (SCF) were found significantly overexpressed. Besides, the cytokines CD30 ligand/tumor necrosis factor superfamily, member 8 (TNFSF8), chordin-like 2, FGF-10/KGF-2, growth/differentiation factor 15, I-TAC/CXCL11, OSM, and SCF were differentially expressed in response to treatment. We propose a role for FGF-10/KGF-2, I-TAC/CXCL11, OSM, osteoactivin/glycoprotein nonmetastatic melanoma protein B, and SCF as novel diagnostic biomarkers. CD30 ligand/TNFSF8, chordin-like 2, FGF-10/KGF-2, growth/differentiation factor 15, I-TAC/CXCL11, OSM, and SCF might represent as predictive biomarkers for gemcitabine and erlotinib response of patients with pancreatic cancer.

    Objective:To investigate cytokine profile in patients with chikungunya virus (CHIKV) infection. Methods: Twenty eight pairs of serum samples collected from CHIKV infected patients during the outbreak of chikungunya fever in South Thailand in 2008 were obtained. A multiple cytokine assay for detection of 17 cytokines was performed. Results:In the acute stage of CHIKV infection, the patients had significantly higher levels of interleukin-6, granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, monocyte chemotactic protein 1 and tumor necrosis factor alpha than the control (P<0.001, P=0.023, P=0.015, P<0.001 and P=0.024, respectively). When the disease developed to the recovery stage, the patients had significantly lower levels of interleukin-6, granulocyte-macrophage colony-stimulating factor, monocyte chemotactic protein 1 and macrophage inflammatory protein beta than in the acute stage (P<0.001). Conclusions:This study provides additional information that these cytokines could play roles in pathogenesis of CHIKV infection and could be used as disease biomarkers or drug targets.

    Full Text Available Diabetic peripheral neuropathy (DPN is a frequent complication of type 2 diabetes mellitus (DM and may involve small and large peripheral nerve fibers. Recent evidence suggests a role of cytokines in DPN. The paper is aimed at exploring whether the serum concentration of cytokines is associated with small and large nerve fiber function and with neuropathic pain (NP. We recruited a group of 32 type 2 DM patients who underwent serum cytokines (TNF-α, IL-2, IL-4, IL-6, and IL-10 dosage as well as electrodiagnostic and quantitative sensory testing (QST assessment to explore damage to large and small nerve fibers. Raised serum levels of IL-6 and IL-10 correlated with markers of large nerve fiber sensory and motor axonal damage. Raised IL-10 serum level was associated with signs of motor nerve demyelination. No differences were found in pain characteristics and electrodiagnostic and QST markers of small nerve fiber function in relation to cytokines serum levels. IL-6 and IL-10 serum levels were associated with large nerve fiber damage but not to small fibers function or NP. IL-6 and IL-10 cytokines might play a role in the pathogenesis of nerve fiber damage or represent a compensatory or neuroprotective mechanism.

    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.

    Coeliac disease is an autoimmune disease characterized by inflammation localized to the small bowel, but less is known about systemic signs of inflammation. The aim was to measure cytokines of the T helper 1 (Th1) and T helper 2 (Th2) cell patterns in children with screening-detected coeliac disease before and after treatment with a gluten-free diet. Serum samples selected before and after the start of a gluten-free diet from 26 3-year-old children diagnosed with biopsy-proven coeliac disease and from 52 matched controls were assayed in an multiplex enzyme-linked immunosorbent assay (ELISA) for the 10 cytokines: interferon (IFN)-γ, interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-8, IL-10, IL-12p70, IL-13 and tumour necrosis factor (TNF)-α. Among Th1 cytokines, IFN-γ and IL-12p70 were elevated significantly in children with coeliac disease compared to controls (P coeliac disease detected by screening demonstrate elevated levels of serum cytokines at time of diagnosis. A prolonged systemic inflammation may, in turn, contribute to long-term complications known to be associated with untreated coeliac disease. © 2014 British Society for Immunology.

    Background: Endometriosis is a frequent gynecologic disease with a severe impact on the quality of life in the affected women; its pathogenesis is yet to be fully understood, with an altered immunity as a possible key factor. The present study aimed to investigate the serum anti-inflammatory cytokine profile in the patients with endometriosis compared with the healthy controls. Materials and Methods: One hundred and sixty women were included, divided into two study groups (Group I — endometriosis; Group 2 — healthy women). We evaluated the serum levels of interleukin-1 receptor antagonist (IL-1Ra), IL-2, IL-2R, IL-4, IL-10, IL-13, and IL-15 with the use of Human multiplex cytokine panels. Statistical analyses (normality distribution analysis, independent t-test, Mann–Whitney U-test) were performed using IBM SPSS software (version 22.0) and GraphPad Prism (version 5.00); receiver operating characteristic curve were used to demonstrate the diagnostic performance of the studied markers. Results: The mean serum level of IL-1Ra, IL-4, and IL-10 were significantly higher in women with endometriosis compared to women free of disease from the control group (30.155, 138.459, and 1.489, respectively, compared to 14.109, 84.710, and 0.688, respectively; P < 0.001, P < 0.001, and P = 0.002, respectively.). No significant differences in the mean serum levels of IL-2, IL-13, and IL-15 were observed between the studied groups and IL-2R had a very low detection rate. Conclusion: Endometriosis is associated with elevated levels of anti-inflammatory cytokines, IL-1Ra, IL-4, and IL-10, markers that have a potential role as a prognostic factor for endometriosis.

    Sulfur mustard (SM) is an incapacitating chemical warfare agent that was used against Iranian soldiers during the period from 1983 to 1988. We have investigated serum cytokines profiles of Khorasan veterans who were exposed to SM >23 years earlier. Forty-four male Iranian veterans who had >40% disabilities due to delayed complications of SM poisoning and had disabilities were investigated. A total of 30 healthy male volunteers (relatives of the veterans) were selected as the control group. Cytokine levels were measured in the serum of case and control subjects using commercial ELISA kits. Hematologic parameters (white/red blood cell counts, hemoglobin levels, immune cell differentials) were also performed on blood samples from the study subjects. The results indicated that serum levels of ICAM-1 were significantly higher in the samples from SM-exposed veterans (772.8 [± 15.1] ng/ml [p=0.014] vs. control values of 710.2 [± 20.0] ng/ml). On the other hand, serum IL-1β, IL-8 levels and TNFα, were significantly lower for the veterans than the controls (IL-1β: 3.8 [± 0.1] vs. 4.3 [± 0.2] pg/ml, p=0.037; IL-8: 21.0 [± 6.1] vs. 84.6 [± 20.3] pg/ml, p=0.002; TNFα: 4.5 [± 0.1] vs. 5.5 [± 0.1] pg/ml, p=0.027). Levels of other assayed cytokines, e.g., IL-2, -4, -5, -6, -10, and -12, IFNγ, TNFβ, and sVCAM-1 were not significantly different between the study populations. None of the assayed hematologic parameters appeared to differ as well. It seems possible that dysfunctions could have been induced in the innate immune functions of the SM-exposed veterans as a result of these changes in cytokine expression and that these, in turn, may have contributed to the increased incidence of a myriad of diseases that have been documented in these veterans, including cancers. Future studies must focus on examining the significance of these changes in circulating cytokines and their potential contribution to the development of different diseases in veterans exposed to SM.

    Full Text Available Here, we aimed to examine the associations between levels of serum 25-hydroxyvitamin D [25(OHD] and inflammatory cytokines in healthy Japanese adults. A total of 95 healthy adults (61 women; age range 21–69 years participated in our study. Fasting blood samples were analyzed for 25(OHD, 1,25-dihydroxyvitamin D [1,25(OH2D], interferon-γ (IFN-γ, interleukin-6 (IL-6, and interleukin-17 (IL-17 levels using enzyme-linked immunosorbent assays kits. Total percent body fat was determined by dual energy X-ray absorptiometry (DXA. Moderate to vigorous physical activity (MVPA was assessed objectively using an activity monitor for 7 days. The mean 25(OHD concentration was 34.7 nmol/L, and 83 subjects had 25(OHD concentrations less than 50 nmol/L. Multiple linear regression analysis revealed that serum 25(OHD level was positively related to plasma IL-17 level (β = 0.26, p = 0.025, after adjustment for gender, age, vitamin D intake, alcohol consumption, smoking status, and percent body fat. This relationship remained statistically significant (β = 0.28, p = 0.019 even after additional adjustment for MVPA. However, no significant association was found between serum 25(OHD level and plasma IFN-γ or IL-6 levels. In conclusion, this study identified a high prevalence of vitamin D deficiency in healthy Japanese adults. Serum 25(OHD level was positively related to IL-17 level, independent of physical activity.

    Full Text Available Objective. In this study, we aimed to investigate the possible role of serum cytokines in the development of hepatic osteodystrophy. Matherial and Methods. 44 consecutive male cirrhotic patients (17 alcoholic, 20 hepatitis B, 7 hepatitis C, 15 age- and sex-matched chronic alcoholics without liver disease, and 17 age- and sex-matched healthy controls were included in the study during one year period. Bone mineral density was measured by dual X-ray absorptiometry in the lumbar vertebrate and femoral neck. Serum interleukin levels were measured by ELISA method. Results. Although osteopenia frequency between our cirrhotic patients was 20%, there was no difference in T-scores among the controls and other groups. Serum interleukin-1, interleukin-8, and tumor necrosis factor-alpha levels were not different between all groups. Serum interleukin-2 and interleukin-6 levels were higher in the cirrhotics than controls (P<0.001. However, there were no significant difference between osteopenic and nonosteopenic cirrhotics. Conclusion. According to the results of the study in this small population of 44 male cirrhotic patients, frequency of hepatic osteopenia is small and serum interleukins 1, 2, 6, 8, and tumor necrosis factor-alpha may not play a role in the pathogenesis of hepatic osteodystrophy. Further studies in which large number of patients involved are necessary in this field.

    The disrupted autoimmune response in Hashimoto's thyroiditis (HT) has long been considered to be dominantly T helper type 1 (Th1) mediated. Recent advances in the field of immunology have introduced a new class of effector T cells, named 'Th17', which plays important roles in autoimmune disorders once thought to be merely Th1 mediated. We aimed to examine the levels of major Th17 cytokines in patients with HT in this study. We studied serum interleukin 17 (IL-17) and interleukin 23 (IL-23) levels in 46 newly diagnosed, untreated patients with HT (40 women and 6 men, aged 40.0 ± 11.8 years) divided into euthyroid (n=22) and hypothyroid (n=24) groups and compared them with age and sex matched 26 healthy euthyroid controls without HT (21 women and 5 men; aged 36.0 ± 12.9 years). Serum IL-17 and IL-23 levels were significantly different among euthyroid and hypothyroid HT patients and controls, with highest levels obtained in the euthyroid HT group (p=0.041 for IL-17 and pdisease affect Th17 system in chronic autoimmune thyroiditis needs to be determined with further studies.

    Human cystic echinococcosis (CE), caused by Echinococcus granulosus, is one of the most important and widespread parasitic zoonoses. One of the problems that can be encountered after treating CE patients is the risk of post-surgical relapses or treatment failure, thus a long-term clinical and serological follow-up is required to evaluate the success or failure of therapy. In the present study immunological markers have been identified to indicate the effectiveness of pharmacological and surgical treatments. The relationship between serum cytokine levels and the outcome of chemotherapy and surgery was evaluated in 50 patients with CE. Serum interleukin (IL)-4, IL-10 and interferon-gamma (IFN-γ) concentrations were determined by enzyme-linked immunosorbent assay (ELISA) before and after pharmacological and surgical treatment. Serum cytokine levels of IL-4, IL-10 and IFN-γ were elevated in a significant proportion of patients during the active stage of disease. IL-4, IL-10 and IFN-γ were measurable in 41 (82%), 37 (74%) and 25 (50%) patients before the treatment. Clinical and radiological assessment of patients 2 years after pharmacological treatment has shown that 48 of 50 patients responded to treatment. IL-4 and IL-10 levels were decreased significantly (P< 0.05) in these patients. Conversely, patients who did not respond showed high levels of IL-4 and IL-10 and undetectable levels of IFN-γ. Hence these results suggest that serum IL-4 and IL-10 detection may be useful in the follow-up of patients with CE.

    Obesity is an inflammatory state characterized by an augment in circulating inflammatory factors. Leptin may modulate the synthesis of these factors by white adipose tissue decreasing insulin sensitivity. We have examined the effect of chronic central administration of leptin on circulating levels of cytokines and the possible relationship with cytokine expression and protein content as well as with leptin and insulin signaling in subcutaneous and visceral adipose tissues. In addition, we analyzed the possible correlation between circulating levels of cytokines and peripheral insulin resistance. We studied 18 male Wistar rats divided into controls (C), those treated icv for 14 days with a daily dose of 12 μg of leptin (L) and a pair-fed group (PF) that received the same food amount consumed by the leptin group. Serum leptin and insulin were measured by ELISA, mRNA levels of interferon-γ (IFN-γ), interleukin-2 (IL-2), IL-4, IL-6, IL-10 and tumor necrosis factor-α (TNF-α) by real time PCR and serum and adipose tissue levels of these cytokines by multiplexed bead immunoassay. Serum leptin, IL-2, IL-4, IFN-γ and HOMA-IR were increased in L and TNF-α was decreased in PF and L. Serum leptin and IL-2 levels correlate positively with HOMA-IR index and negatively with serum glucose levels during an ip insulin tolerance test. In L, an increase in mRNA levels of IL-2 was found in both adipose depots and IFN-γ only in visceral tissue. Activation of leptin signaling was increased and insulin signaling decreased in subcutaneous fat of L. In conclusion, leptin mediates the production of inflammatory cytokines by adipose tissue independent of its effects on food intake, decreasing insulin sensitivity. PMID:23056516

    Objectives This article reports relationships between serum cytokine levels and patient-reported levels of fatigue, in the chronic immunological condition primary Sjögren's syndrome (pSS). Methods Blood levels of 24 cytokines were measured in 159 patients with pSS from the United Kingdom Primary Sjögren's Syndrome Registry and 28 healthy non-fatigued controls. Differences between cytokines in cases and controls were evaluated using Wilcoxon test. Patient-reported scores for fatigue were evaluated, classified according to severity and compared with cytokine levels using analysis of variance. Logistic regression was used to determine the most important predictors of fatigue levels. Results 14 cytokines were significantly higher in patients with pSS (n=159) compared to non-fatigued healthy controls (n=28). While serum levels were elevated in patients with pSS compared to healthy controls, unexpectedly, the levels of 4 proinflammatory cytokines—interferon-γ-induced protein-10 (IP-10) (p=0.019), tumour necrosis factor-α (p=0.046), lymphotoxin-α (p=0.034) and interferon-γ (IFN-γ) (p=0.022)—were inversely related to patient-reported levels of fatigue. A regression model predicting fatigue levels in pSS based on cytokine levels, disease-specific and clinical parameters, as well as anxiety, pain and depression, revealed IP-10, IFN-γ (both inversely), pain and depression (both positively) as the most important predictors of fatigue. This model correctly predicts fatigue levels with reasonable (67%) accuracy. Conclusions Cytokines, pain and depression appear to be the most powerful predictors of fatigue in pSS. Our data challenge the notion that proinflammatory cytokines directly mediate fatigue in chronic immunological conditions. Instead, we hypothesise that mechanisms regulating inflammatory responses may be important. PMID:27493792

    Full Text Available Introduction : Localized scleroderma is an autoimmune disease primarily affecting the skin. The cause of disease remains unexplained although environmental factors are implicated, which are likely to be responsible for activation of the endothelium and subsequent inflammation leading to excessive synthesis of collagen and extracellular matrix components. Aim: To determine concentrations of interleukin (IL-27, transforming growth factor (TGF-β1, TGF-β2, IL-6, and sIL-6R in patients with localized scleroderma compared to controls and to assess the relations between their levels and laboratory markers. Material and methods: The study encompassed 17 females with localized scleroderma (aged 25–67. The control group consisted of 30 age-matched healthy women. The blood was sampled from the basilic vein. Serum levels of cytokines were determined using ELISA. Results : The TGF-β2 levels were found to be significantly lower in patients with localized scleroderma compared to controls. Concentrations of TGF-β1 were decreased in scleroderma patients when compared to controls but without statistical significance. There were no significant differences in serum IL-6, sIL-6R and IL-27 levels between patients and the control group; however, we found a significant positive correlation between the level of sIL-6 and ESR among subjects with localized scleroderma. Conclusions : The findings of decreased serum levels of TGF-β1 and TGF-β2 in patients with localized scleroderma demonstrate a possible association of these cytokines with pathogenesis of the disease. The results suggest also that sIL-6R is likely to be involved in inflammation in patients with localized scleroderma.

    Full Text Available Abstract Background Fibromyalgia (FM is characterized by chronic, widespread muscular pain and tenderness and is generally associated with other somatic and psychological symptoms. Further, circulatory levels of proinflammatory cytokines (IL-1β, TNF-α, and IL-6 may be altered in FM patients, possibly in association with their symptoms. Recently, rises in BMI have been suggested to contribute to increased circulating levels of proinflammatory cytokines in FM patients. Our aim was to measure the circulatory levels of proinflammatory cytokines to determine the influence of BMI on these levels in FM patients and healthy volunteers (HVs. In Spanish FM patients (n = 64 and HVs (n = 25, we measured BMI and serum concentrations of proinflammatory cytokines by capture ELISA. Findings There were significant differences in BMI levels between FM patients (26.40 ± 4.46 and HVs (23.64 ± 3.45 and significant increase in IL-6 in FM patients (16.28 ± 8.13 vs 0.92 ± 0.32 pg/ml (P Conclusions Our analysis in FM patients of BMI as a covariate of proinflammatory cytokines levels showed that serum TNF-α and IL-6 levels are independent of BMI. Further studies are necessary to dissect these findings and their implication in future therapeutic approaches for FM patients.

    Full Text Available BACKGROUND: Severe fever with thrombocytopenia syndrome virus (SFTSV, which can cause hemorrhagic fever-like illness, is a newly discovered bunyavirus in China. The pathogenesis of SFTSV infection is poorly understood. However, it has been suggested that immune mechanisms, including cytokines and chemokines, play an important role in disease pathogenesis. In the present study, we investigated host cytokine and chemokine profiles in serum samples of patients with SFTSV infection from Northeast China and explored a possible correlation between cytokine levels and disease severity. METHODS AND PRINCIPAL FINDINGS: Acute phase serum samples from 40 patients, diagnosed with SFTSV infection were included. Patients were divided into two groups--severe or non-severe--based on disease severity. Levels of tumor necrosis factor (TNF-α, transforming growth factor (TGF-β, interleukin-6, interferon (IFN-γ, IFN- γ-induced protein (IP-10 and RANTES were measured in the serum samples with commercial ELISAs. Statistical analysis showed that increases in TNF-α, IP-10 and IFN-γ were associated with disease severity. CONCLUSIONS: We suggest that a cytokine-mediated inflammatory response, characterized by cytokine and chemokine production imbalance, might be in part responsible for the disease progression of patients with SFTSV infection.

    Full Text Available Objectives. In this study, we assessed the extra-articular symptoms in constellation with selected serum cytokines and disease activity in spondyloarthritis (SpA. Patients and Methods. We studied 287 SpA patients: 131 had AS, 110 had PsA, and 46 had SAPHO. We assessed extra-articular symptoms in all cases. In 191 SpA patients, we measured serum interleukin-6 (IL-6, interleukin-18 (IL-18, interleukin-23 (IL-23, endothelin-1 (ET-1, vascular endothelial growth factor (VEGF, and epidermal growth factor (EGF. Results. Patients with acute anterior uveitis (AAU had higher VAS (P=0.0008, BADSDAI (P=0.0001, ASDAS-ESR (P=0.04, CRP (P=0.006, IL-6 (P=0.02, and IL-18 (P=0.03 levels. Patients with inflammatory bowel disease (IBD had higher VAS (P=0.03, CRP (P=0.0009, and IL-6 (P=0.0003 levels. Patients with skin psoriasis had lower VAS (P=0.001 and BASDAI (P=0.00007 levels. Patients with psoriatic onycholysis had lower VAS (P=0.006, BASDAI (P=0.00001, and CRP (P=0.02 and higher IL-23 (P=0.04 levels. Patients with PPP had lower BASDAI (P=0.04 and higher ET-1 (P=0.001 levels. Conclusions. SpA patients with increased serum IL-18 and decreased serum ET-1 had an increased risk of extra-articular symptoms. In SpA patients, increased disease activity was associated with an increased risk of AAU and IBD and a decreased risk of skin psoriasis, psoriatic onycholysis, and PPP.

    Although several theories have been proposed including developmental/neurodegenerative processes, neurotransmitter abnormalities, viral infection, and immune dysfunction, the exact causative factor of schizophrenia is unclear. A relationship between inflammation and schizophrenia has been supported by abnormal cytokine production and altered antioxidant status. This study was aimed to examine the alterations in serum oxidative-antioxidative status and cytokine levels of schizophrenic patients. A total of 91 schizophrenic patients from Saudi Arabia and 50 age- and sex-matched healthy controls were enrolled in the present study. Fresh blood samples were collected to measure the levels of cytokines and markers of oxidative stress by spectrophotometric assays simultaneously. We observed that there was a significant increase in the levels of tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 and a decrease in the levels of interferon-γ. Lipid peroxides are elevated in serum, while total-sulfhydryl levels were decreased. Also, the activities of superoxide dismutase and glutathione peroxidase were decreased, while the activities of catalase, glutathione reductase, and myeloperoxidase were found to be elevated in serum. We conclude that inflammation resulting from dysregulation of cytokines and altered antioxidant systems may play a critical role in the etiology of schizophrenia.

    Tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) has been implicated in the pathogenesis of a variety of inflammatory disorders and autoimmune diseases. However, studies conducted on the relationship of TWEAK and psoriasis patients are limited. In this study, we aimed to explore the serum levels of TWEAK and investigated whether TWEAK levels are associated with clinical variables and expression of other well-known psoriasis-related cytokines including IL-6, IL-23 and TNF-α. Forty-five patients with chronic plaque psoriasis and 43 controls were enrolled in this study. The severity of psoriasis was assessed by the Psoriasis Area and Severity Index (PASI). Serum levels of cytokines were measured using commercial enzyme-linked immunosorbent assay (ELISA) kits. The mean TWEAK, IL-6, IL-23, and TN-α levels were significantly higher in psoriasis patients than in control subjects. However, there were no significant correlations between the psoriasis severity, the illness duration and serum cytokine levels. This study shows that TWEAK may be associated with the pathogenesis of psoriasis, like TNF-α, IL-6, and IL-23.

    Amyloid A (AA) protein is derived from serum amyloid A (SAA) and deposited as beta-pleated sheet fibrils in reactive amyloidosis, a disease that occurs spontaneously in golden Syrian hamsters. The precursor SAA is an acute-phase reactant in many species including hamsters, and in this report we have defined the in vivo kinetic and dosage responses for SAA mRNA accumulation in hamsters following administration of various cytokines. Elevations in levels of hepatic SAA mRNA were documented when the doses of interleukin-1, interleukin-6, and tumor necrosis factor were increased. The increase in dosages applied ranged from 2 1/2-fold for interleukin-6 to 10-fold for interleukin-1. SAA transcript levels were highest 8 h following administration of interleukin-6 or tumor necrosis factor, whereas maximal amounts of SAA-specific mRNA were found 24 h after administration of interleukin-1.

    Although estrogen reduces inflammatory-mediated pain responses, the mechanisms behind its effects are unclear. This study investigated if estrogen modulates inflammatory signaling by reducing baseline or inflammation-induced cytokine levels in the injury-site, serum, dorsal root ganglia (DRG) and/or spinal cord. We further tested whether estrogen effects on cytokine levels are in part mediated through hypothalamic-pituitary-adrenal (HPA) axis activation. Lumbar DRG, spinal cord, serum, and hind paw tissue were analyzed for cytokine levels in 17β-estradiol-(20%) or vehicle-(100% cholesterol) treated female rats following ovariectomy/sham adrenalectomy (OVX), adrenalectomy/sham ovariectomy (ADX) or ADX+OVX operation at baseline and post formalin injection. Formalin significantly increased pro-inflammatory interleukin (IL)-6 levels in the paw, as well as pro- and anti-inflammatory cytokine levels in the DRG, spinal cord and serum in comparison to naïve conditions. Estrogen replacement significantly increased anti-inflammatory IL-10 levels in the DRG. Centrally, estradiol significantly decreased pro-inflammatory tumor necrosis factor (TNF)-α and IL-1β levels, as well as IL-10 levels, in the spinal cord in comparison to cholesterol treatment. At both sites, most estradiol modulatory effects occurred irrespective of pain or surgical condition. Estradiol alone had no influence on cytokine release in the paw or serum, indicating that estrogen effects were site-specific. Although cytokine levels were altered between surgical conditions at baseline and following formalin administration, ADX operation did not significantly reverse estradiol's modulation of cytokine levels. These results suggest that estrogen directly regulates cytokines independent of HPA axis activity in vivo, in part by reducing cytokine levels in the spinal cord.

    Peripheral blood mononuclear cells (PBMCs) were isolated from the whole blood of cheetahs (Acinonyx jubatus ; n=3) and stimulated with lipopolysaccharides (LPS) to induce the production of proinflammatory cytokines TNF-α, IL-1β, and IL-6 for establishment of cross-reactivity between these cheetah cytokines and feline-specific cytokine antibodies provided in commercially available Feline DuoSet® ELISA kits (R&D Systems, Inc., Minneapolis, Minnesota 55413, USA). This study found that feline-specific cytokine antibodies bind specifically to cheetah proinflammatory cytokines TNF-α, IL-1β, and IL-6 from cell culture supernatants. The assays also revealed that cheetah PBMCs produce a measurable, cell concentration-dependent increase in proinflammatory cytokine production after LPS stimulation. To enable the use of these kits, which are designed for cell culture supernatants for analyzing cytokine concentrations in cheetah serum, percent recovery and parallelism of feline cytokine standards in cheetah serum were also evaluated. Cytokine concentrations in cheetah serum were approximated based on the use of domestic cat standards in the absence of cheetah standard material. In all cases (for cytokines TNF-α, IL-1β, and IL-6), percent recovery increased as the serum sample dilution increased, though percent recovery varied between cytokines at a given dilution factor. A 1:2 dilution of serum resulted in approximately 45, 82, and 7% recovery of TNF-α, IL-1β, and IL-6 standards, respectively. Adequate parallelism was observed across a large range of cytokine concentrations for TNF-α and IL-1β; however, a significant departure from parallelism was observed between the IL-6 standard and the serum samples (P=0.004). Therefore, based on our results, the Feline DuoSet ELISA (R&D Systems, Inc.) kits are valid assays for the measurement of TNF-α and IL-1β in cheetah serum but should not be used for accurate measurement of IL-6.

    Full Text Available The clinical-immunological spectrum of human Leishmania (L. infantum chagasi infection in Amazonian Brazil was recently reviewed based on clinical, DTH, and IFAT (IgG evaluations that identified five profiles: three asymptomatic (asymptomatic infection, AI; subclinical resistant infection, SRI; and indeterminate initial infection, III and two symptomatic (symptomatic infection, SI; American visceral leishmaniasis, AVL; and subclinical oligosymptomatic infection, SOI. TNF-α, IL-4, IL-6, and IL-10 serum cytokines were analyzed using multiplexed Cytometric Bead Array in 161 samples from endemic areas in the Brazilian Amazon: SI [AVL] (21 cases, III (49, SRI (19, SOI (12, AI (36, and a control group [CG] (24. The highest IL-6 serum levels were observed in the SI profile (AVL; higher IL-10 serum levels were observed in SI than in SOI or CG and in AI and III than in SOI; higher TNF-α serum levels were seen in SI than in CG. Positive correlations were found between IL-6 and IL-10 serum levels in the SI and III profiles and between IL-6 and TNF-α and between IL-4 and TNF-α in the III profile. These results provide strong evidence for associating IL-6 and IL-10 with the immunopathogenesis of AVL and help clarify the role of these cytokines in the infection spectrum.

Conclusion No evidence was found that serum irisin concentrations in mothers at pregnancy termination or those of their newborns correlated with maternal body mass index, the presence of diabetes mellitus, or free fatty acid levels. However, the results of this study indicated that cytokines might predict irisin concentration in mothers and their offspring, although interactions between irisin levels during pregnancy and the newborn have not yet been fully elucidated.

    The association between attachment style and subjective pain is controversially discussed and the influence of attachment styles on cytokine levels in chronic pain has received little attention in research. In this prospective longitudinal clinical study, we evaluated the relationship between cytokines, attachment style and subjective pain intensity as well as pain-related functioning in patients with fibromyalgia (FM) who underwent a 4-week multidisciplinary pain therapy. The attachment style was determined in 43 patients with FM using the relationship questionnaire (RQ-2) and subjective pain with the German version of the West Haven-Yale multidimensional pain inventory. Serum levels of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α) and interleukin 8 (IL-8) and the anti-inflammatory cytokines IL-4 and IL-10 were assessed before and after treatment and additionally once only in 18 healthy controls (Bio-Plex system). Patients with FM syndrome were significantly more often insecurely attached than healthy controls (p = 0.001). Serum levels of TNF-α (p = 0.001) and IL-10 (p = 0.039) were significantly higher in FM patients compared to controls. Attachment was unrelated to IL-4, IL-8, and IL-10 levels. Insecurely attached FM patients had significantly higher levels of TNF-α (p = 0.002). than securely attached patients. Insecurely and securely attached patients did not differ in subjective levels of pain severity, activity or functional interference. Cytokine levels were not correlated with subjective levels of pain severity or functional interference. Multidisciplinary pain therapy significantly reduced cytokine levels, pain severity, anxiety and depression independent of attachment style.

    Full Text Available "nBackground: The annual amount of mortality in ESRD exceeds the expectation and represents the recent evidences of the inflammation as its etiology. The etiology of inflammation is not clearly known. Chronic inflammation is a dominant occurrence of ESRD which increases the risk of atherosclerosis, malnutrition and peripheral vascular disease. Inflammatory responses are orchestrated by cytokines. Some of the proinflammatory cytokines like IL-6 have a crucial role in this phenomenon. The IL-6 and its receptor activity is up regulated in ESRD patients and the increased level of IL-6 predicts cardiovascular mortality and morbidity in normal and CRF patients. This study devotes itself to determining the serum level of IL-6 and factors affecting it in patients undergoing chronic hemodialysis in Imam Khomeini Hospital which can represent the Iranian Society. By identifying factors affecting the serum level of IL-6 and high-risk patients we can provide treatment possibilities, a decrease in mortality and an improvement in its prognosis.

    Febrile seizures are the most common form of childhood seizures. Fever is induced by pro-inflammatory cytokines during infection, and pro-inflammatory cytokines may trigger the development of febrile seizures. In order to determine whether active inflammation, including high mobility group box-1 (HMGB1) and pro-inflammatory cytokines, occurs in children with febrile seizures or epilepsy, we analyzed cytokine profiles of patients with febrile seizures or epilepsy. Forty-one febrile seizure patients who visited the emergency department of Seoul National University Boramae Hospital from June 2008 to May 2009 were included in this study. Blood was obtained from the febrile seizure child patients within 30 minutes of the time of the seizure; subsequently, serum cytokine assays were performed. Control samples were collected from children with febrile illness without convulsion (N = 41) and similarly analyzed. Serum samples from afebrile status epilepticus attacks in intractable epilepsy children (N = 12), afebrile seizure attacks in generalized epilepsy with febrile seizure plus (GEFSP) children (N = 6), and afebrile non-epileptic controls (N = 7) were also analyzed. Serum HMGB1 and IL-1β levels were significantly higher in febrile seizure patients than in fever only controls (p febrile seizures than in fever only controls (p febrile seizure children. Although it is not possible to infer causality from descriptive human studies, our data suggest that HMGB1 and the cytokine network may contribute to the generation of febrile seizures in children. There may be a potential role for anti-inflammatory therapy targeting cytokines and HMGB1 in preventing or limiting febrile seizures or subsequent epileptogenesis in the vulnerable, developing nervous system of children.

    In this study, effect of flunixin meglumine on serum tumour necrosis factor alpha, (TNFalpha) interleukin-1 beta and interleukin-10 levels was investigated in lipopolysaccharide-induced endotoxic mice. Healthy 273 Balb/C mice were used and divided into three equal groups. Group 1 was injected lipopolysaccharide (Escherichia coli 0111:B4, 250 microg/mouse, intraperitoneally), Group 2 was injected flunixin meglumine (2.5 mg/kg, subcutaneously), and Group 3 was injected lipopolysaccharide + flunixin meglumine. After the treatments, at 0., 1., 2., 3., 6., 12., 24th hours and 3., 5., 7., 14., 21., 28th days blood samples were taken from seven mice in each group. Serum TNFalpha, interleukin-1 beta and interleukin-10 levels were measured using commercially available kits by enzyme-linked immunoassay. Flunixin meglumine did not affect the cytokine levels in healthy animals. While lipopolysaccharide increased serum TNFalpha, interleukin-1 beta and interleukin-10 levels, flunixin meglumine inhibited increases at levels of all cytokines. As result, flunixin meglumine showed depressor effect on cytokine levels in endotoxemia and the effect may be a reason for the first chosen member of nonsteroid anti-inflammatory drug in endotoxemia.

    Short bowel syndrome is a severe malabsorption disorder, and prolonged parenteral nutrition is essential for survival in some cases. Among the undesirable effects of long-term parenteral nutrition is an increase in proinflammatory cytokines. The aim of the present study was to measure the serum levels of interleukin-6, interleukin-10, tumor necrosis factor alpha, and transforming growth factor beta, in patients with short bowel syndrome on cyclic parenteral nutrition and patients who had previously received but no longer require parenteral nutrition. The study was cross-sectional and observational. Three groups were studied as follows: Parenteral nutrition group, 9 patients with short bowel syndrome that receive cyclic parenteral nutrition; Oral nutrition group, 10 patients with the same syndrome who had been weaned off parenteral nutrition for at least 1 year prior to the study; Control group, 13 healthy adults, matched for age and sex to parenteral and oral groups. The following data were collected: age, tobacco use, drug therapies, dietary intake, body weight, height, blood collection. All interleukins were significantly higher in the parenteral group compared with the control group as follows: interleukin-6: 22 ± 19 vs 1.5 ± 1.4 pg/mL, P= .0002; transforming growth factor β: 854 ± 204 vs 607 ± 280 pg/mL, P= .04; interleukin-10: 8 ± 37 vs 0.6 ± 4, P= .03; tumor necrosis factor α: 20 ± 8 vs 8 ± 4 pg/mL, Pshort bowel syndrome patients, regardless of its duration, increases serum proinflammatory cytokines.

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

    Previous studies have demonstrated that exercise-induced asthma and bronchial hyperresponsiveness commonly occur in athletes. The present study investigates pulmonary function and cytokine levels in professional athletes to explore the impact of various sports on respiratory system function and to evaluate the possible role of systemic anaphylaxis. Lung function was measured at rest in professional athletes without a history of smoking. Athletes were recruited from 10 different sports including swimming, water ballet, shooting, volleyball, softball, football, kickboxing, fencing, judo, and track and field. Measurements included forced vital capacity (FVC), forced expiratory volume in one second (FEV(1)), vital capacity (VC), peak expiratory flow (PEF), maximal mid-expiratory flow curve (MMEF), and forced expiratory flow rate (FEF(25-75)%). In addition, the medical history of all athletes was recorded. Correlations between lung function measurements and the different sports, age, gender, height and weight were analyzed. In some athletes, serum was sampled to detect IL-4 and IL-10 concentrations. In these subjects, the correlation between pulmonary function and cytokine levels was analyzed. A total of 147 professional athletes and 30 healthy volunteers were enrolled in the study. Allergic rhinitis and asthma were detected only in swimmers with an incidence of 56.52% (13/23) and 8.70% (2/23), respectively. Lung function measures were significantly correlated with sport, age, gender, height, and weight. Ventilation functions (including FVC, FEV(1), FEV(1)/FVC, and MMV) in male athletes were superior to those in females, and the ventilation functions in swimmers were superior to those in others. However, the small airway functions (MMEF, FEF(50), FEF(75)) in swimmers and in track and field athletes were lower than predicted (swimmers: 72%, 70%, and 78%, respectively; track and field athletes: 79%, 75%, and 99%, respectively). Serum analyses for IL-4 and IL-10 revealed

    Space flight is a unique experience and results in adverse effects on human physiology. Changes have been reported in various physiological systems, including musculoskeletal, neurovestibular, cardiovascular, endocrine, immunity and increased latent viral reactivation as well as others. The potential mechanisms behind these changes are not fully understood. Various cytokines such as IL-1, IL-6, TNF and chemokines have been linked to several of these changes, like muscle loss, bone loss, fatigue, sleep deprivation and viral reactivation. Eighteen astronauts (15 M and 3 F) from 8 spaceflights and 10 healthy age-matched adults (6 M, 4 F) were included in the present study. A panel of 21 plasma cytokines was analyzed with the Luminex 100 to measure the cytokines in these subjects 10 days before the flight (L-10), 2-3 hour after landing (R+0), 3 days after landing (R+3), and at their annual medical exam (AME). IL-10, IL-1, IFN-alpha, MCP-1 and IP-10 increased significantly at L-10 as compared with AME levels. IL-6 and IFN-alpha showed significant increases at R + 0 (P less than .05) over their baseline levels (AME). Cytokine levels at R+3 were not significantly different from R+0. IL-10 and IL-6 have been reported to increase in during viral reactivation. These data show that there was a shift from TH1 to TH2 cytokines L-10 and R+0. We also studied viral reactivation in 10 of the 18 subjects included in the present study before, during, and after space flight. Increased salivary varicella zoster virus (VZV) shedding in these subjects was found either during or after the mission. VZV shedding correlated with the increased levels of cytokines especially IL-10 and IL-6. Overall, our data suggests that cytokines may play an important role in regulating adverse changes in astronauts, and further studies are needed to fully understand the mechanism.

    Several lines of evidence suggest that neuroimmune mechanisms may be involved in the neurodegenerative process of Parkinson's disease (PD). Interleukin-6 (IL-6) is increased in the nigrostriatal region and in the cerebrospinal fluid of patients with PD. IL-6 serum level was evaluated in PD patients. The effects of levodopa treatment and disease severity on IL-6 were also studied. The IL-6 levels were similar between PD patients (treated and not treated) and controls. However, there was a negative correlation of IL-6 levels and the activities of daily living scale (P < 0.05), indicating that patients with more severe disease have higher levels of this cytokine. No correlation involving levodopa treatment and IL-6 serum level was found. The results suggest that only marginal effects of IL-6 occur on the peripheral immune system, and that the role of IL-6 and others neuroimmune factors needs to be well elucidated on PD.

    Purpose Low-grade inflammation, measured by circulating levels of cytokines, is a pathogenic mechanism for several chronic diseases of aging. Identifying factors related to inflammation among African American youths may yield insights into mechanisms underlying racial disparities in health. The purpose of the study was to determine whether (a) reported racial discrimination from ages 17 to 19 forecast heightened cytokine levels at age 22, and (b) this association is lower for youths with positive racial identities. Methods A longitudinal research design was used with a community sample of 160 African Americans who were 17 at the beginning of the study. Discrimination and racial identity were measured with questionnaires, and blood was drawn to measure basal cytokine levels. Ordinary least squares regression analyses were used to examine the hypotheses. Results After controlling for socioeconomic risk, life stress, depressive symptoms, and body mass index, racial discrimination (β = .307, p racial identity (β = −.179, p racial discrimination evinced elevated cytokine levels 3 years later. This association was not significant for young adults with positive racial identities. Conclusions High levels of interpersonal racial discrimination and the development of a positive racial identity operate jointly to determine low-grade inflammation levels that have been found to forecast chronic diseases of aging, such as coronary disease and stroke.

    Background:Inflammatory bowel disease( IBD)is a group of chronic and non-specific intestinal inflammatory diseases of undetermined origin. Functional impairment of macrophages has been associated with the dysregulation of mucosal immunity in intestinal tract of patients with IBD. Aims:To investigate the correlation of serum levels of macrophage polarization-related cytokines with the development and disease activity of IBD. Methods:A total of 105 IBD patients admitted from May 2013 to May 2014 at Shanghai Ruijin Hospital were recruited,of them 65 were Crohn’s disease (CD)and 40 were ulcerative colitis( UC). Twenty-four patients with colonic polyps were served as controls. Serum samples were obtained and the levels of interleukin-1beta(IL-1β),IL-6,IL-10,IL-13,interferon-gamma(IFN-γ)and inducible nitric oxide synthase(iNOS)were determined by ELISA method. Results:Serum levels of IL-1β,IL-6,IL-10, IL-13 and IFN-γ were significantly higher in CD group than in control group(P 0. 05). Conclusions:Serum levels of macrophage polarization-related cytokines increase to varying degrees in IBD patients,but these cytokines have no obvious correlations with IBD and its disease activity. Presumably,theses cytokines are only involved in but not the triggers in the development of IBD.%背景:炎症性肠病(IBD)是一组病因不明的慢性非特异性肠道炎症性疾病。IBD 患者体内巨噬细胞功能常有不同程度受损,导致肠道黏膜免疫紊乱。目的:探讨血清巨噬细胞极化相关细胞因子水平与 IBD 及其活动度的关系。方法:收集2013年5月-2014年5月上海瑞金医院住院 IBD 患者105例,其中克罗恩病(CD)65例,溃疡性结肠炎(UC)40例,同期24例结肠息肉患者作为对照组。采集受检者血清标本,以 ELISA 法检测血清白细胞介素-1β(IL-1β)、IL-6、IL-10、IL-13、干扰素-γ(IFN-γ)、诱导型一氧化氮合酶(iNOS)水平。结果:CD 组血清 IL-1

    This study characterized the proinflammatory cytokines, interleukin-2 (IL-2) and tumor necrosis factor alpha (TNFalpha), the antiinflammatory cytokines, IL-4 and IL-10, autoantibodies specific for GM1 ganglioside (anti-GM1), IgG and IgM, and myelin-associated glycoprotein (anti-MAG), in the sera of infection-free, chronic (>12 months), traumatically injured SCI patients (n = 24). Healthy able-bodied subjects (n = 26) served as controls. The proinflammatory cytokines and anti-GM1 antibodies were of particular interest as they have been implicated in an autoimmune "channelopathy" component to central and peripheral conduction deficits in various chronic neuroinflammatory diseases. Antibody and cytokine titers were established using enzyme-linked immunosorbent assays (ELISA). The mean anti-GM(1) (IgM) titer value for the SCI group was significantly higher (p proinflammatory cytokines relative to control values. These results provide preliminary support for the hypothesis that chronic immunological activation in the periphery occurs in a subpopulation of chronic SCI patients. It remains to be established whether elevated serum titers of proinflammatory cytokines and autoantibodies against GM1 are beneficial to the patients or whether they are surrogate markers of a channelopathy that compounds the neurological impairment associated with traumatic axonopathy or myelinopathy.

    To determine whether horses with clinically diagnosed Equine Recurrent Uveitis (ERU) and those with Leptospirosis infection have a specific cytokine profile in their aqueous humor (AH) and serum that differs from horses with uveitis secondary to other ocular inflammatory processes and from horses with normal eyes. Twenty-five client-owned horses with uveitis that were presented to the North Carolina State University Ophthalmology Service, and four University-owned horses without history or clinical signs of ocular disease. Samples of AH and serum were obtained from horses with ERU (n=13), acute or non-recurrent uveitis (UV; n=7), uveitis secondary to infectious keratitis (IK; n=5), and normal eyes (N; n=4). Cytokine levels in AH and serum were quantified using a multiplex bead immunoassay. Leptospiral antibody titers in serum and AH and PCR for Leptospiral DNA in AH were performed. In the AH of horses with ERU, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, FGF-2, G-CSF, and RANTES were measured compared to UV, IK and N eyes, but the differences were not significant. However, IL-10 was significantly higher in ERU eyes compared to IK and N (P=0.029; 0.013), and IP-10 in ERU eyes was significantly higher than in UV and N (P=0.004). Furthermore, MCP-1 was significantly higher in ERU than N (P=0.04). In the serum, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, fractalkine, and G-CSF were measured in horses with ERU, but the levels were not significantly higher than those observed in UV, IK, or N horses. However, serum IP-10 levels in horses with ERU were significantly higher than in UV and N horses (P=0.005) and MCP-1 levels were significantly higher in ERU than N (P=0.03). Horses with marked ocular inflammation had significantly higher serum levels of G-CSF, IL-1a, fractalkine, IL-13, IL-4, IL-17a, IL-12p70, IFN-γ, and MCP-1. Elevated IL-10 in AH was significantly associated with disease chronicity, both overall and in ERU eyes (P=0.049), and in

    In sepsis, dysregulation of the immune response leads to rapid multiorgan failure and death. Accurate and timely diagnosis is lifesaving and should discriminate sepsis from the systemic inflammatory response syndrome (SIRS) caused by non-infectious agents. Osteopontin acts as an extracellular matrix component or a soluble cytokine in inflamed tissues. Its exact role in immune response and sepsis remains to be elucidated. Therefore, we investigated the role of osteopontin in SIRS and sepsis. Prospective, observational study. Intensive care unit of a university hospital. Fifty-six patients with SIRS or sepsis and 56 healthy subjects were enrolled. We analyzed the serum levels of osteopontin and TH1-TH2 cytokines and investigated the role of osteopontin on interleukin 6 secretion by monocytes. Serum osteopontin levels were strikingly higher in patients than in controls and in sepsis than in SIRS, and decreased during the resolution of both the disorders. Receiver operating characteristic curves showed that osteopontin levels have discriminative power between SIRS and sepsis with an area under the curve of 0.796. Osteopontin levels directly correlated with those of interleukin 6 and in vitro, recombinant osteopontin increased interleukin 6 secretion by monocytes in both the absence and presence of high doses of lipopolysaccharide. These data suggest that osteopontin might be a mediator involved in the pathogenesis of SIRS and sepsis, possibly by supporting interleukin 6 secretion. 45. SIRS/Sepsis: clinical studies.

    To investigate the features of various hepatitis virus infection in intravenous drug users (IVDU), we conducted an epidemiological survey of hepatitis viruses including hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis G virus (HGV) in IVDU. The correlation of TH lymphocyte cytokine and hepatitis virus infection was examined. A study population of 406 IVDU consisted of 383 males and 23 females. HBV-DNA and HCV-RNA were detected by fluorescence quantitative polymerase chain reaction. HBsAg, HBeAg, anti-HBc,anti-HCV, HDV-Ag and anti-HGV were assayed by ELISA. The levels of cytokines of TH 1 and TH2 were measured by ELISA. The similar indices taken from 102 healthy persons served as controls. The infection-rate of each virus among IVDU was 36.45 % for HBV, 69. 7 % for HCV,2.22 % for HDV, and 1. 97 % for HGV, respectively. The co-infection rate of HBV and HCV was detected in 113 of 406 (27. 83%). In contrast, among controls, the infection rate was 17.65 % for HBV and 0% for the other hepatitis viruses. The levels of PHA-induced cytokines (IFN-γ and IL-4) and the level of serum IL 2 were obviously decreased in IVDU. On the other hand, the level of serum IL-4 was increased. The IFN-γ level was continuously decreased when the IVDU was infected with HBV/HCV. In conclusion, HBV and HCV infection were common in this population ofIVDU and they had led to a high incidence of impaired TH 1 cytokine levels.

    Full Text Available Herpes zoster is a viral disease caused by the reactivation of varicella-zoster virus (VZV which remained latent in the cranial nerve or dorsal root ganglia. Cell-mediated immunity is known to decline with age as part of immunosenescence and can lead to the reactivation of VZV. Whereas herpes zoster is usually mild in healthy young persons, older patients are at increased risk for complications. In the present study we investigated the serum cytokine profile (IL-17, IL-23, IL-21, IL-4, IL-12, representing cellular and humoral immunity and assessed the level of VZV IgG antibodies in patients with herpes zoster.We investigated the serum concentrations of IL-17, IL-23, IL-21, IL-4, IL-12 and the level of VZV IgG antibodies in 23 patients with herpes zoster who did not develop superinfection. The control group was represented by 21 individuals in similar age with no inflammatory and infectious diseases. Cytokine and antibodies levels were measured by ELISA method. Statistical analysis was performed using the ROC curve (receiver operating characteristic, t-test, Welch's t-test, and nonparametric tests with STATISTICA 10 software.In patients with herpes zoster, the serum level of IL-17, IL-23, IL-21, IL-4 and IL-12 as well as VZV IgG antibodies titer were statistically significantly increased compared to control group.Our results confirm the broad activation of the immune system involving humoral and cell-mediated immunity.

    Full Text Available Endocan is a newly recognized biomarker of sepsis. However, there have been no studies of the trends in endocan levels during infection and their associations with other clinical factors. The aim of this study was to assess the time course of endocan levels and the associations of endocan with clinical factors during infection by comparison with other biomarkers.Serum samples and blood cultures were obtained from patients who were diagnosed with infection from June 2013 to March 2014. Serum endocan, C-reactive protein (CRP, and procalcitonin (PCT levels during four periods during infection were measured (day 0, day 1-2, day 3-5, and day 6-10.A total of 78 patients were enrolled in this study. The median endocan level decreased by only 23% during infection, whereas both serum CRP and PCT levels decreased by more than 80%. Endocan levels were correlated to neither CRP levels nor PCT levels in each period. Endocan levels at day 0 in patients with bacteremia were higher than those without bacteremia (1.09 ng/mL vs 0.82 ng/mL, P=0.002, but neither CRP levels nor PCT levels at day 0 were different between the two groups. Areas under the receiver operator characteristic (ROC curves of endocan, CRP, and PCT at day 0 were 0.662, 0.343, and 0.563, respectively. Positive blood cultures tended to be related to high endocan levels, but not significantly (odds ratio: 4.24, 95% CI: 0.99-10.34, P=0.05.In bacteremic cases, serum endocan levels in bacteremia tended to be higher than in non-bacteremic cases. Although endocan level was not identified as a prognostic factor of bacteremia, further prospective study concerning the relationship between serum endocan level and bacteremia would be needed.

    Full Text Available To investigate the usefulness of serum cytokine dosage in the clinical management of cystic echinococcosis (CE, we analyzed serum levels of Th1 and Th2 cytokines in patients with hepatic CE in different cyst stages, CE1-2 (active, CE3a-3b (transitional, and CE4-5 (inactive. Ex vivo assessment of Th1 (IFN-γ and Th2 (IL-4, IL-13, and IL-10 cytokines in sera was carried out using ELISA. IL-10 was undetectable in all serum samples of patients and controls, while a few sera contained measurable amounts of IFN-γ, IL-4, and IL-13. No statistically significant difference was found between the percentages of positive samples for each cytokine and the different groups analyzed (patients/controls, stage, number, location, and size of the cyst, serology, and sex of patients, with the exception of the association of IL-4 and IL-13 with the cyst stage. Overall, this investigation showed many limits of serum cytokine dosage as a marker of biological activity of echinococcal cysts. Because of low sensitivity and lack of specificity of this test, we believe that other ways to evaluate ex vivo biological activity of the cysts should be explored.

    Hypotheses regarding an immune-cytokine basis of schizophrenia have been postulated with controversial findings and a lack of data related to many cytokines. The aim of this study was to assess serum levels of Interferon-γ (IFN-γ), Interleukin-4 (IL-4), Transforming Growth Factor-β (TGF-β), Interleukin-17 (IL-17) and B-cell Activating Factor (BAFF) in schizophrenic patients and to determine correlations between cytokine levels and clinical parameters. Serum cytokine levels were measured with ELISA techniques in 60 neuroleptic-free patients on acute phase of the disease (BPRS≥40) and 28 healthy controls matched for age and sex. Current symptoms were assessed with Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), Scale for the Assessment of Positive Symptoms (SAPS) and Scale for the Assessment of Negative Symptoms (SANS). No significant difference was found between patients and controls regarding IFN-γ serum levels. IL-4 was not detected in both groups. Patients exhibited significantly higher IL-17 and lower BAFF serum levels. IL-17 and BAFF levels were negatively correlated in schizophrenic patients. SANS global score was negatively correlated with IL-17 and positively correlated with IFN-γ serum levels. These results argue against the involvement of Th1 or Th2 population cells in schizophrenia. IL-17 and BAFF could be valuable markers for schizophrenia.

    Objective To determine if serum 25-hydroxy-vitamin D was associated with inflammatory cytokines, interleukin-10 (IL-10), and tumour necrosis factor-α(TNF-α) levels in patients with inactive Crohn’s disease (CD). Methods 35 adults with quiescent CD were divided into vitamin D-insufifcient group (group A) and vitamin D-replete group (group B) according to serum 25-hydroxy-vitamin D levels. Then serum IL-10 and TNF-αlevel were detected by ELISA and compared. After vitamin D supplement to patients in group A, serum IL-10 and TNF-αlevels were detected again and compared to previous levels. Result Serum IL-10 levels of patients in group A were signiifcantly lower compared with group B (P0.05). The use of a vitamin D supplement did not signiifcantly inlfuence serum IL-10 and TNF-αlevel (P>0.05). Conclusions Circulating levels of IL-10, but not TNF-alpha, were signiifcantly lower in CD patients with inadequate serum 25-hydroxy-vitamin D. This suggests that poor vitamin D status may be linked to reduced anti-inlfammatory capacity in these patients.%目的探讨缓解期克罗恩病患者血清25-羟基维生素D与炎性细胞因子白细胞介素-10(interleukin-10,IL-10)及肿瘤坏死因子-α(tumour necrosis factor-α,TNF-α)的关系。方法根据血清维生素D水平将35例缓解期克罗恩病患者分为维生素D缺乏组(A组)和维生素D充足组(B组),采用ELISA检测两组患者入组时及A组患者经补充维生素D治疗后的血清IL-10和TNF-α水平。结果 A、B两组患者血清TNF-α水平比较无统计学差异(P>0.05),A组患者血清IL-10水平显著低于B组(P<0.05);A组患者经补充维生素D治疗后血清IL-10和TNF-α水平与治疗前比较无统计学差异(P>0.05)。结论存在维生素D缺乏的克罗恩病患者循环IL-10水平显著降低,提示维生素D缺乏可能与这些患者的抗炎能力下降有关。

    DENV infection can induce different clinical manifestations varying from mild forms to dengue fever (DF) or the severe hemorrhagic fever (DHF). Several factors are involved in the progression from DF to DHF. No marker is available to predict this progression. Such biomarker could allow a suitable medical care at the beginning of the infection, improving patient prognosis. The aim of this study was to compare the serum expression levels of acute phase proteins in a well-established cohort of dengue fever (DF) and dengue hemorrhagic fever (DHF) patients, in order to individuate a prognostic marker of diseases severity. The serum levels of 36 cytokines, chemokines and acute phase proteins were determined in DF and DHF patients and compared to healthy volunteers using a multiplex protein array and near-infrared (NIR) fluorescence detection. Serum levels of IL-1ra, IL-23, MIF, sCD40 ligand, IP-10 and GRO-α were also determined by ELISA. At the early stages of infection, GRO-α and IP-10 expression levels were different in DF compared to DHF patients. Besides, GRO-α was positively correlated with platelet counts and IP-10 was negatively correlated with total protein levels. These findings suggest that high levels of GRO-α during acute DENV infection may be associated with a good prognosis, while high levels of IP-10 may be a warning sign of infection severity.

    The production of several cytokines could be dysregulated in type 1 diabetes (T1D). In particular, the activation of T helper (Th) type 1 (Th1) cells has been proposed to underlie the autoimmune pathogenesis of the disease, although roles for inflammatory processes and the Th17 pathway have also been shown. Nevertheless, despite evidence for the role of cytokines before and at the onset of T1D, the corresponding findings are inconsistent across studies. Moreover, conflicting data exist regarding the blood cytokine levels in T1D patients. The current study was performed to investigate genetic and autoantibody markers in association with the peripheral blood cytokine profiles by xMap multiplex technology in newly diagnosed young T1D patients and age-matched healthy controls. The onset of young-age T1D was characterized by the upregulation of growth factors, including granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin (IL)-7, the proinflammatory cytokine IL-1β (but not IL-6 or tumor necrosis factor [TNF]-α), Th17 cytokines, and the regulatory cytokines IL-10 and IL-27. Ketoacidosis and autoantibodies (anti-IA-2 and -ZnT8), but not human leukocyte antigen (HLA) genotype, influenced the blood cytokine levels. These findings broaden the current understanding of the dysregulation of systemic levels of several key cytokines at the young-age onset of T1D and provide a further basis for the development of novel immunoregulatory treatments in this disease.

    目的 探讨不同程度间歇低氧对大鼠血清炎性细胞因子白介素8(IL-8)和抗炎细胞因子IL-10水平的影响.方法 160只雄性Wistar大鼠随机分为5组:5%,7.5%,10%间歇低氧组,10%持续低氧对照组和常氧对照组各32只,分别于低氧暴露第2周、第4周、第6周和第8周每组随机抽取8只大鼠,应用酶联免疫吸附试验法检测血清IL-8和IL-10浓度.结果 各间歇低氧组和持续低氧组血清IL-8水平均随低氧时间呈明显升高(F=6.42,P<0.01),IL-10水平明显降低(F=5.787,P<0.01).在低氧6周时所有间歇低氧组出现明显的峰值,5%,7.5%,10%间歇低氧组IL-8水平明显高于10%持续低氧对照组和常氧对照组(P值均<0.01),而IL-10水平明显低于10%持续低氧对照和常氧对照组(P<0.01).其中5%间歇低氧组血清IL-8水平明最高于10%间歇低氧组(F=34.68,P=0.046).结论 间歇性低氧和持续性低氧均可造成促炎性细胞因子IL-8的升高和抗炎性细胞因子IL-10的降低.间歇低氧可能比持续低氧引起更严重的炎性损伤反应,且炎性因子的释放存在明显的低氧程度依赖性和低氧时间依赖性.%Objective To investigate the effects of different degree of intermittent hypoxia on serum levels of pre-inflammatory cytokines interleukin-8 (IL-8) and anti-inflammatory cytokines IL-10 in rats.Methods One hundred and sixty male Wistar rats were divided randomly into the five groups: 5%,7. 5%, 10% of intermittent hypoxia group, 10% sustained hypoxia control group and the normal oxygen control group. At the second, fourth, sixth, and eighth weeks, 8 rats under different environmental stimulation hypoxia in each group were sacrificed to collect serum. Enzyme Linked Immuno Sorbent Assay (ELISA) assay were used to detect the concentration of serum IL-8 and IL-10.

    African swine fever virus (ASFV), the causative agent of one of the most important viral diseases of domestic pigs for which no vaccine is available, causes immune system disorders in infected animals. In this study, the serum levels of proinflammatory cytokines, as well as the histological and cellular constitution of lymphoid organs of pigs infected with ASFV genotype II were investigated. The results showed a high degree of lymphocyte depletion in the lymphoid organs, particularly in the spleen and lymph nodes, where ASFV infection led to a twofold decrease in the number of lymphocytes on the final day of infection. Additionally, ASFV-infected pigs had atypical forms of lymphocytes found in all lymphoid organs. In contrast to lymphocytes, the number of immature immune cells, particularly myelocytes, increased dramatically and reached a maximum on day 7 postinfection. The serum levels of TNF-α, IL-1β, IL-6, and IL-8 were evaluated. Proinflammatory cytokines showed increased levels after ASFV infection, with peak values at 7 days postinfection, and this highlights their role in the pathogenesis of ASFV. In conclusion, this study showed that ASFV genotype II, like other highly virulent strains, causes severe pathological changes in the immune system of pigs.

    Clinical studies have shown that moderate whisky consumption increased renal excretion of urate into urine and decreased serum urate level, but the mechanism involved has not been established. Because renal reabsorption influences serum urate level, the effects of the whisky congeners on urate transporters, urate transporter 1 (URAT1), and voltage-driven urate transporter (URATv1) involved in reabsorptive transport of urate were examined. In transporter-expressing Xenopus oocytes, 12-year-old and 18-year-old whisky congeners inhibited urate uptake by URAT1 with IC50 values of 0.08 ± 0.01 and 0.04 ± 0.01 mg/mL, respectively, while urate uptake by URATv1 was inhibited only at 1 mg/mL. Decreased serum urate level after whisky consumption may be mainly due to inhibition of URAT1 by the congeners.

    Full Text Available This study was designed to compare the bone mineral density (BMD in 108 postmenopausal women with laboratory data including osteocalcin, intact parathyroid hormone and serum cytokine values. One hundred eigth postmenopausal women were randomly divided into 3 sub groups according to their BMD and medical treatment. The first group consisting of 18 postmenopausal women had no osteoporosis, mean age and mean duration of postmenopausal period were 52.94± 4.90 and 6.5±4.76 years respectively. The second group consisting of 15 postmenopausal women had osteoporosis and was not treated, mean age and mean duration of postmenopausal period were 53.60±8.84 and 9.73± 6.75 years respectively. The third group consisting of 75 postmenopausal osteoporotic women was under medical treatment, mean age nd mean duration of postmenopausal period were 58.52±8.51 and 13.20±8.41 years respectively. Bone mineral density at femur Ward’s triangle, trochanter and lumbar spine t score values were evaluated by dual X ray absorptiometry (DXA. Serum calcium, phosphorous, C-reactive protein, erythrocyte sedimentation rate, cytokines (interleukin-1, IL-1, interleukin-2, IL-2, interleukin-6, IL-6, interleukin-8, IL-8 and tumor necrosis factor alpha TNF-a, osteocalcin, intact parathyroid hormone were measured. In subjects, no significant correlation was observed between BMD t scores of lumbar spine, trochanter, Ward’s triangle and cytokine values. On the other hand, among these groups significant difference was found between age, treatment duration, t scores of lumbar spine, trochanter, Ward’s triangle and postmenopausal period, but not between IL-1, IL-2, IL-6, IL-8, TNF-a, osteocalcin, intact parathyroid. As a conclusion we think BMD (especially in the early postmenopausal period might be correlating with the levels of cytokines in bone microenvironment rather than serum levels. In the early postmenopausal osteoporosis period serum IL-6 value might be supporting to

    Interleukin-13 (IL-13) is an immunosuppressive cytokine produced by several immune cells and cancer cells. The aim of this retrospective study was to determine if serum IL-13 levels have an association with clinical outcome in patients with colorectal cancer. A total of 241 patients with colorectal cancer were enrolled in the present study. Preoperative serum IL-13 concentrations were measured by enzyme-linked immunosorbent assay. We analyzed the association of serum IL-13 levels with clinicopathological variables. Patients with lymph node metastasis, lymphatic invasion, vascular invasion, distant metastases or advanced stage of disease had significantly lower serum IL-13 levels. Low serum IL-13 was significantly associated with both poor recurrence-free and overall survival. Multivariate analysis showed that low IL-13 levels were an independent predictive marker for poor prognosis. In conclusion, our data suggest that low serum IL-13 levels may be a useful predictive marker for poor prognosis in colorectal cancer.

    Secondary insults, such as hemorrhagic shock (HS), worsen outcome from traumatic brain injury (TBI). Both TBI and HS modulate levels of inflammatory mediators. We evaluated the addition of HS on the inflammatory response to TBI. Adult male C57BL6J mice were randomized into five groups (n=4 [naïve] or 8/group): naïve; sham; TBI (through mild-to-moderate controlled cortical impact [CCI] at 5 m/sec, 1-mm depth), HS; and CCI+HS. All non-naïve mice underwent identical monitoring and anesthesia. HS and CCI+HS underwent a 35-min period of pressure-controlled hemorrhage (target mean arterial pressure, 25-27 mm Hg) and a 90-min resuscitation with lactated Ringer's injection and autologous blood transfusion. Mice were sacrificed at 2 or 24 h after injury. Levels of 13 cytokines, six chemokines, and three growth factors were measured in serum and in five brain tissue regions. Serum levels of several proinflammatory mediators (eotaxin, interferon-inducible protein 10 [IP-10], keratinocyte chemoattractant [KC], monocyte chemoattractant protein 1 [MCP-1], macrophage inflammatory protein 1alpha [MIP-1α], interleukin [IL]-5, IL-6, tumor necrosis factor alpha, and granulocyte colony-stimulating factor [G-CSF]) were increased after CCI alone. Serum levels of fewer proinflammatory mediators (IL-5, IL-6, regulated upon activation, normal T-cell expressed, and secreted, and G-CSF) were increased after CCI+HS. Serum level of anti-inflammatory IL-10 was significantly increased after CCI+HS versus CCI alone. Brain tissue levels of eotaxin, IP-10, KC, MCP-1, MIP-1α, IL-6, and G-CSF were increased after both CCI and CCI+HS. There were no significant differences between levels after CCI alone and CCI+HS in any mediator. Addition of HS to experimental TBI led to a shift toward an anti-inflammatory serum profile--specifically, a marked increase in IL-10 levels. The brain cytokine and chemokine profile after TBI was minimally affected by the addition of HS.

    Abstract Some observational studies have shown that elevated serum selenium levels are associated with reduced prostate cancer risk; however, not all published studies support these results. A literature search of PubMed, Embase, Medline, and the Cochrane Library up until September 2016 identified 17 studies suitable for further investigation. A meta-analysis was conducted on these studies to investigate the association between serum selenium levels and subsequent prostate cancer risk. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the overall OR of prostate cancer for the highest versus the lowest levels of serum selenium. We found a pooled OR (95% CI) of 0.76 (0.64, 0.91; P selenium levels and prostate cancer risk was found in each of case–control studies, current and former smokers, high-grade cancer cases, advanced cancer cases, and different populations. Such correlations were not found for subgroups containing each of cohort studies, nonsmokers, low-grade cancer cases, and early stage cancer cases. In conclusion, our study suggests an inverse relationship between serum selenium levels and prostate cancer risk. However, further cohort studies and randomized control trials based on non-Western populations are required. PMID:28151881

    Cytokines play diverse and critical roles in innate and acquired immunity, and several function within the central nervous system and in peripheral tissues to modulate energy metabolism. The extent to which changes in energy balance impact the expression and circulating levels of cytokines (many of which have pleiotropic functions) has not been systematically examined. To investigate metabolism-related changes in cytokine profiles, we used a multiplex approach to assess changes in 71 circulating mouse cytokines in response to acute (fasting and refeeding) and chronic (high-fat feeding) alterations in whole body metabolism. Refeeding significantly decreased serum levels of IL-22, IL-1α, soluble (s)IL-2Rα, and soluble vascular endothelial growth factor receptor 3 (VEGFR3), but markedly increased granulocyte colony-stimulating factor (G-CSF), IL-1β, chemokine (C-C motif) ligand (CCL2), sIL-1RI, lipocalin-2, pentraxin-3, tissue inhibitor of metalloproteinase (TIMP-1), and serum amyloid protein (SAP) relative to the fasted state. Interestingly, only a few of these changes paralleled the alterations in expression of their corresponding mRNAs. Functional studies demonstrated that central delivery of G-CSF increased, whereas IL-22 decreased, food intake. Changes in food intake were not accompanied by acute alterations in orexigenic (Npy and Agrp) and anorexigenic (Pomc and Cart) neuropeptide gene expression in the hypothalamus. In the context of chronic high-fat feeding, circulating levels of chemokine (C-X-C) ligand (CXCL1), serum amyloid protein A3 (SAA3), TIMP-1, α1-acid glycoprotein (AGP), and A2M were increased, whereas IL-12p40, CCL4, sCD30, soluble receptor for advanced glycation end products (sRAGE), CCL12, CCL20, CX3CL1, IL-16, IL-22, and haptoglobin were decreased relative to mice fed a control low-fat diet. These results demonstrate that both short- and long-term changes in whole body metabolism extensively alter cytokine expression and circulating levels

    We evaluated the usefulness of individual tryptase levels and variations after adverse drug reactions in 64 patients. Our aim was to find a tool for the diagnosis of drug allergy. Thirty-seven subjects were confirmed to have drug allergy, 12 had nonsteroidal anti-inflammatory drug (NSAID) reactions, five had negative controlled drug challenges (NAAR), and 10 had symptoms after placebo intake (PLA). Serum tryptase levels greatly increased after anaphylactic shocks (2242%) and anaphylaxis (710.5%). Patients with allergic urticaria and those with idiosyncratic responses to acetylsalicylic acid (ASA) exhibited a small increase in serum tryptase (49.5% and 38.2%, respectively). In the other two groups (NAAR and PLA), no variation in this serum protease was observed. The time of appearance of the serum tryptase peak differed considerably among patients with similar clinical reactions (from 30 min to 6 h) and was independent of the latent period, severity of symptoms, or the amount of tryptase released. We conclude that serum tryptase determinations are helpful in the diagnosis of anaphylactic shock and anaphylaxis, but serial measurements may be needed to confirm mast-cell participation in milder reactions.

The main aim of this study was to investigate the serum level of IL12 in OBI patients.Materials and methods: In this study, the plasma samples of 3700 HBsAg negative blood donors were tested for anti-HBs by ELISA. The HBsAg negative and anti-HBc positive samples were selected and screened for HBV-DNA by PCR. HBV-DNA positive samples were assigned as OBI cases and ELISA technique were performed to examine the serum level of IL-12 in OBI and 100 healthy controls.Results: Our results showed that there was no significant difference in serum level of IL-12 between OBI patients and controls.Conclusion: In order to be clear of viruses, L-12 is increased in viral infection. Based on the results of this study, it is concluded that OBI patients can not produce enough IL-12 to clear HBV. J Mazand Univ Med Sci 2009; 19(72: 81-83 (Persian

    Full Text Available Although it is recognized that the mechanical stresses associated with physical activity augment bone mineral density and improve bone quality, our understanding of how exercise modulates bone homeostasis at the molecular level is lacking. In a before and after trial involving 43 healthy adults, we measured the effect of six months of supervised exercise training on the spontaneous and phytohemagglutinin-induced production of osteoclastogenic cytokines (interleukin-1α, tumor necrosis factor-α, antiosteoclastogenic cytokines (transforming growth factor-β1 and interleukins 4 and 10, pleiotropic cytokines with variable effects on osteoclastogenesis (interferon-γ, interleukin-6, and T cell growth and differentiation factors (interleukins 2 and 12 by peripheral blood mononuclear cells. We also measured lymphocyte phenotypes and serum markers of bone formation (osteocalcin, bone resorption (C-terminal telopeptides of Type I collagen, and bone homeostasis (25 (OH vitamin D, estradiol, testosterone, parathyroid hormone, and insulin-like growth factor 1. A combination of aerobic, resistance, and flexibility exercises done on average of 2.5 hours a week attenuated the production of osteoclastogenic cytokines and enhanced the production of antiosteoclastogenic cytokines. These changes were accompanied by a 16% reduction in collagen degradation products and a 9.8% increase in osteocalcin levels. We conclude that long-term moderate intensity exercise exerts a favorable effect on bone resorption by changing the balance between blood mononuclear cells producing osteoclastogenic cytokines and those producing antiosteoclastogenic cytokines.

    Objective:To investigate the cytokines profile in the serum of some Nigerian children with Ascaris lumbricoides (A. lumbricoides) infection and relations between the intensity of infection, age and the concentration of these cytokines.Methods: Feacal samples from consenting children were examined using formol ether concentration techniques and Kato-Katz thick smear technique. Sera of 96 children comprising 76A. lumbricoides infection and 20 controls were subjected to enzymes-linked immunosorbent assay.Results: The mean sera concentration of tumor necrosis factor alpha (TNF-α), interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-10 (IL-10) were (16.7±7.6) pg/mL, (4.6±0.8)pg/mL, (391.6±52.0) pg/mL and (181.2±30.4) pg/mL, respectively. The control subjects had the following mean serum cytokines: TNF-α(2.9±1.8) pg/m, IL-4 (4.0±0.1) pg/mL, IL-5 (125.1±50.1) pg/mL, IL-10 (74.5±54.2) pg/mL, respectively. The difference between the sera cytokines concentration of theA. lumbricoides infected children and their controls were statistically significant for TNF-α, IL- 5 and IL-10(χ2= 9.99,P< 0.05;χ2 = 137.24,P < 0.05;χ2 = 44.30,P < 0.05, respectively). The intensity of infection correlated positively with TNF-α, and IL-5 (r = 0.93 and 0.98, respectively) while IL-4 and IL- 10 correlated negatively with the intensity of infection (r = -0.62 and 0.99, respectively). TNF-α, IL-4 and IL-5 correlated positively with age (r = 0.19, 0.33 and 0. 66, respectively). The mean cytokines between those with mild and moderate infections were statistically significant for TNF-α, IL-5 and IL-10 (χ2 = 3.60, 4.52 and 5.30, respectively). The ratio of TNF-α: IL-10 was 0.092.Conclusions: Elevated IL-5, IL-10 and TNF-α found in the sera of the volunteers with Ascariasis implicates these cytokines as key mediators in the host responses toA. lumbriocoides infection in our studied area.

    A newborn male with pulmonary edema was delivered at term by elective Caesarian section. Cytokine profiles of 17 cytokines and KL-6 in cord blood and serial serum values were investigated. The cord blood values of all 17 cytokines and KL-6 were within normal limits. Subsequently, IL-6, IL-8, IL-10, IL-13, IL-17, and IFNγ rapidly elevated during the first several hours after birth and dramatically decreased thereafter, whereas KL-6 rose to 611 U/ml on the 3(rd) day of life and then gradually decreased. These cytokines may induce pulmonary permeability, and KL-6 secreted in lining fluid could result in influx into the bloodstream. This is the first report that we have differentiated neonatal pulmonary edema from TTN by the measurement of serial cytokine profiles and KL-6 in serum.

    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.

    This study shows that hemoglobin H disease patients aged between 0.5 and 44 years, usually (27 out of 30) have normal serum ferritin levels according to age. This reconfirms that in this disease there are usually normal iron stores. However, in a few patients (3 out of 30) increased levels were found. This may be due to inappropriate iron medication, transfusions or associated idiopathic hereditary hemocromatosis gene.

    Introduction Recurrent abortion (RA) may be a consequence of aberrant expression of immunological factors during pregnancy. Although the relative importance of immunological factors in human reproduction remains controversial, substantial evidence suggests that autoantibodies contribute to reproductive failure. Production of such antibodies is under the control of cytokines; and leptin, besides its role in reproductive success, has a profound effect on directing the cytokine profile toward Th1 (cellular) pattern. Therefore, the present study was performed to assess serum leptin levels in women with immunological recurrent abortion. Materials and Methods In this prospective study, 250 women who attended Avicenna Infertility Clinic with RA were screened for known causes of abortion from July to December 2008 in Tehran, Iran. Eighty-one patients with normal karyotypes and hormonal profile with normal ovaries and uterus and no signs of infection were categorized as patients with immunological (IRA, n = 39) or unexplained (URA, n = 42) recurrent abortion based on presence or absence of autoantibodies. After blood sampling, levels of anti-nuclear antibody (ANA), anti-double stranded DNA antibody (anti-dsDNA), lupus anti-coagulant antibody (LACAb), anti-phospholipid antibody (APA), anti-cardiolipin antibody (ACA), anti-thyroglobulin antibody (TgAb), anti-thyroperoxidase antibody (TPOAb) and anti-thrombin III antibody (ATIIIAb) were measured by enzyme-linked immunosorbent assay (ELISA) or chemiluminescent enzyme immunoassay (CLEIA). Results In IRA group, 9 (23.1%), 24 (61.5%), 25(64.1%) and 1 (2.6%) women were above the normal cut-off point for ANA, TgAbs, TPOAbs and AT-III Abs, respectively. IRA patients had normal values of LACAbs, APA and ACA. With normal level of fasting blood sugar (FBS), IRA and URA groups had similar serum leptin levels (23.7 ± 13.2 ng/ml vs. 22.7 ± 12.5 ng/ml, respectively). Serum leptin concentrations showed a positive correlation with weight

    Cytokines and chemokines have been analysed in patients with oral squamous cell carcinoma and potentially malignant disorders. We selected interleukin-6 (IL-6) because it is a multifunctional interleukin reported to be altered in potentially malignant oral disorders and in malignant lesions. To date, this has not been evaluated or tested in proliferative verrucous leukoplakia (PVL), however. This study aimed to analyse the differences in serum and saliva IL-6 levels among patients with PVL, oral squamous cell carcinoma (OSCC) and healthy controls and to examine the relationship between salivary IL-6 levels and the extent of the verrucous area. Using an enzyme-linked immunosorbent assay, we determined the serum and saliva IL-6 levels in three groups: 20 patients with PVL, 20 with OSCC and 20 healthy controls. There were significant (p verrucous areas (p = 0.01). In the OSCC group, there was a significant difference in the saliva IL-6 levels between patients with and without lymph node metastasis at diagnosis (p = 0.02). We found that patients with OSCC had the highest salivary and serum IL-6 levels, while PVL had lower values than OSCC, but higher than the controls, and these altered levels were associated with the extent of the verrucous areas. Salivary and plasma IL-6 are altered in patients with PVL, with more extensive verrucous areas being associated to the highest IL-6 levels. This could be a significant tool for monitoring patients with PVL, their progression to more advances stages and their recurrences.

    Aim and Background Herpes zoster is a viral disease caused by the reactivation of varicella–zoster virus (VZV) which remained latent in the cranial nerve or dorsal root ganglia. Cell-mediated immunity is known to decline with age as part of immunosenescence and can lead to the reactivation of VZV. Whereas herpes zoster is usually mild in healthy young persons, older patients are at increased risk for complications. In the present study we investigated the serum cytokine profile (IL-17, IL-23, IL-21, IL-4, IL-12), representing cellular and humoral immunity and assessed the level of VZV IgG antibodies in patients with herpes zoster. Methods We investigated the serum concentrations of IL-17, IL-23, IL-21, IL-4, IL-12 and the level of VZV IgG antibodies in 23 patients with herpes zoster who did not develop superinfection. The control group was represented by 21 individuals in similar age with no inflammatory and infectious diseases. Cytokine and antibodies levels were measured by ELISA method. Statistical analysis was performed using the ROC curve (receiver operating characteristic), t-test, Welch’s t-test, and nonparametric tests with STATISTICA 10 software. Results In patients with herpes zoster, the serum level of IL-17, IL-23, IL-21, IL-4 and IL-12 as well as VZV IgG antibodies titer were statistically significantly increased compared to control group. Conclusion Our results confirm the broad activation of the immune system involving humoral and cell-mediated immunity. PMID:26934574

    Immune abnormalities have been described in some individuals with autism spectrum disorders (ASD) as well as their family members. However, few studies have directly investigated the role of prenatal cytokine and chemokine profiles on neurodevelopmental outcomes in humans. In the current study, we characterized mid-gestational serum profiles of 22 cytokines and chemokines in mothers of children with ASD (N=415), developmental delay without ASD (DD) (N=188), and general population (GP) controls (N=428) using a bead-based multiplex technology. The ASD group was further divided into those with intellectual disabilities (DQ<70) (ASD+ID, N=184) and those without (DQ≥70) (ASD-noID, N=201). Levels of cytokines and chemokines were compared between groups using multivariate logistic regression analyses, adjusting for maternal age, ethnicity, birth country, and weight, as well as infant gender, birth year, and birth month. Mothers of children with ASD+ID had significantly elevated mid-gestational levels of numerous cytokines and chemokines, such as GM-CSF, IFN-γ, IL-1α, and IL-6, compared to mothers of children with either ASD-noID, those with DD, or GP controls. Conversely, mothers of children with either ASD-noID or with DD had significantly lower levels of the chemokines IL-8 and MCP-1 compared to mothers of GP controls. This observed immunologic distinction between mothers of children with ASD+ID from mothers of children with ASD-noID or DD suggests that the intellectual disability (ID) associated with ASD might be etiologically distinct from DD without ASD. These findings contribute to the ongoing efforts toward identification of early biological markers specific to sub-phenotypes of ASD. PMID:27217154

    stage in SARS patients, the average was still higher than that of the control group (P<0.01).Conclusions Most proinflammatory cytokines and TGF-β1 were elevated during the early phase of SARS, which may be associated with lung infiltration and proliferation. Concurrently, the mean concentration of serum IL-13 decreased gradually, and the mean concentration of serum IL-18 level in SARS patients was lower than that of the control group during all the courses of SARS, suggesting that the immune state of the patients with SARS was obviously abnormal. Observing the dynamic changes in blood cytokine levels can provide a scientific basis to assess pathogenesis and efficacy of clinical treatment of SARS.

    Full Text Available Abstract Background Procalcitonin (PCT is closely correlated with parasite burden and clinical outcome in falciparum malaria. The role of PCT in tertian malaria has not previously been investigated. Patients and methods PCT serum levels in 37 patients with tertian malaria were analysed. Clinical and laboratory parameters were assessed and statistically correlated both to the initial PCT levels and during the course of the disease. Results PCT levels rose for one day after commencing treatment and declined thereafter. However, there was no significant correlation with parasite burden, clinical parameters, laboratory values, or the presence of semi-immunity. Before treatment, the majority of patients showed normal or slightly elevated PCT levels ( Conclusions There is a fundamental difference in the relationship of PCT with tertian malaria not seen in other infectious diseases in which elevated PCT levels have been observed. This suggests distinct pathophysiological pathways in malaria.

    Full Text Available Macrophages are involved in low-grade inflammation in diabetes, and play pathogenic roles in proliferative diabetic retinopathy (PDR by producing proinflammatory cytokines. T cells as well as other cells are also activated by proinflammatory cytokines, and infiltration into the vitreous of patients with PDR has been shown. In this study, we measured helper T (Th cell-related cytokines in the vitreous of PDR patients to define the characteristics of Th-mediated immune responses associated with PDR. The study group consisted of 25 type 2 diabetic patients (25 eyes with PDR. The control group consisted of 27 patients with epiretinal membrane (ERM, 26 patients with idiopathic macular hole (MH, and 26 patients with uveitis associated with sarcoidosis. Vitreous fluid was obtained at the beginning of vitrectomy, and centrifuging for cellular removals was not performed. Serum was also collected from PDR patients. IL-1β, IL-4, IL-6, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, IFN-γ, soluble sCD40L, and TNFα in the vitreous and serum samples were measured. Both percent detectable and levels of IL-4, IL-6, IL-17A, IL-21, IL-22, and TNFα in the vitreous were significantly higher than those in the serum in PDR patients. Vitreous levels of these cytokines and IL-31 were significantly higher in PDR than in ERM or MH patients. Vitreous levels of IL-4, IL-17A, IL-22, IL-31, and TNFα in PDR patients were also significantly higher than those of sarcoidosis patients. In PDR patients, vitreous IL-17A level correlated significantly with vitreous levels of IL-22 and IL-31, and especially with IL-4 and TNFα. Although it is unclear whether these cytokines play facilitative roles or inhibitory roles for the progression of PDR, the present study indicated that Th2- and Th17-related immune responses are involved in the pathogenesis of PDR.

    Crohn's disease (CD) and ulcerative colitis (UC), two forms of inflammatory bowel disease (IBD), are chronic, relapsing, and tissue destructive lesions that are accompanied by the uncontrolled activation of effector immune cells in the mucosa. Recent estimates indicate that there are 1.3 million annual cases of IBD in the United States, 50% of which consists of CD and 50% of UC. Chemokines and cytokines play a pivotal role in the regulation of mucosal inflammation by promoting leukocyte migration to sites of inflammation ultimately leading to tissue damage and destruction. In recent years, experimental studies in rodents have led to a better understanding of the role played by these inflammatory mediators in the development and progression of colitis. However, the clinical literature on IBD remains limited. Therefore, the aim of this study was to evaluate systemic concentrations of key chemokines and cytokines in forty-two IBD patients with a range of disease activity compared to levels found in ten healthy donors. We found a significant increase in an array of chemokines including macrophage migration factor (MIF), CCL25, CCL23, CXCL5, CXCL13, CXCL10, CXCL11, MCP1, and CCL21 in IBD patients as compared to normal healthy donors (Pcytokines IL-16, IFN-γ, IL-1β and TNF-α in IBD patients when compared to healthy donors (Pcytokines that are known to modulate systemic level through immune cells results in affecting local intestinal inflammation and tissue damage in IBD patients. Blockade of these inflammatory mediators should be explored as a mechanism to alleviate or even reverse symptoms of IBD.

    In Chagas disease, chronically infected individuals may be asymptomatic or may present cardiac or digestive complications, and it is well known that the human immune response is related to different clinical manifestations. Different patterns of cytokine levels have been previously described in different clinical forms of this disease, but contradictory results are reported. Our aim was to evaluate the serum levels of interleukin-10 and tumour necrosis factor-alpha in patients with asymptomatic and cardiac Chagas disease. The serum interleukin-10 levels in patients with cardiomyopathy were higher than those in asymptomatic patients, mainly in those without heart enlargement. Although no significant difference was observed in serum tumour necrosis factor-alpha levels among the patients, we found that cardiac patients also present high levels of this cytokine, largely those with heart dilatation. Therefore, these cytokines play an important role in chronic Chagas disease cardiomyopathy. Follow-up investigations of these and other cytokines in patients with chronic Chagas disease need to be conducted to improve the understanding of the immunopathology of this disease. © 2015 John Wiley & Sons Ltd.

    Introduction: Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.[1] Pregnancy is a unique situation in which there is a physiological temporary increase in insulin resistance (IR). The mechanisms responsible for the gestational-induced IR are not completely understood. The current study was undertaken to compare adiponectin levels during 24–28 weeks period of gestation in drug-naive newly diagnosed GDM women with a cohort of normoglycemic pregnant women. Subjects and Methods: A total of 47 pregnant women in the age group of 18–40 years were included in this cross-sectional study, of which 13 were GDM cases and 34 were normoglycemic controls. Serum adiponectin level was analyzed by enzyme-linked immunosorbent assay. Results: The mean adiponectin level was 16.92 ng/ml (standard deviation [SD] = 2.78) and 19.38 ng/ml (SD = 2.71) in case and control groups, respectively, and the difference was found to be statistically significant (P = 0.008). Conclusion: Our study demonstrated decreased serum adiponectin levels in women with GDM when compared with age- and body mass index-matched euglycemic pregnant women. PMID:27867874

    Full Text Available PAF is a potent inflammatory compound known to stimulate the release of various cytokines involved in rheumatic diseases. Elevated blood PAF levels are reported in these patients. We report that serum PAF acetylhydrolase activity (AHA levels are decreased in patients with rheumatoid arthritis or osteoarthritis as compared to healthy controls. Serum and synovial fluid AHA levels were correlated in these patients. The present study suggests the potential role of AHA in controling systemic and/or local PAF levels in patients with rheumatic diseases.

    Full Text Available "nBackground: Maternal zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. Most studies in which pregnant women have been supplemented with zinc to examine its effects on the outcome of the pregnancy have been carried out in industrialized countries and the results have been inconclusive. It has been shown that women with gestational diabetes (GDM have lower serum zinc levels than healthy pregnant women, and higher rates of macrosomia. Zinc is required for normal glucose metabolism, and strengthens the insulin-induced transportation of glucose into cells by its effect on the insulin signaling pathway. The purpose of this study was to assess the serum zinc levels of GDM patients and evaluate the effect of zinc supplementation. "nMethods: In the first stage of this prospective controlled study, we enrolled 70 women who were 24-28 weeks pregnant at the Prenatal Care Center of Mirza Kochak Khan Hospital, Tehran, Iran. The serum zinc level of each subject was determined. In the second stage, among these 70 subjects, the diabetics receiving insulin were divided into two groups, only one of which received a zinc supplement and the other group was the control group. Birth weight of neonates and insulin dosages were recorded. "nResults: The mean serum zinc level in the GDM group was lower than that of the control group (94.83 vs. 103.49mg/dl, respectively and the mean birth weight of neonates from the GDM women who received the zinc supplement was lower than that of the control group (3849g vs. 4136g. The rate of macrosomia was lower in the zinc supplemented group (20% vs. 53%. The mean of increase of insulin after receiving the zinc supplement was lower (8.4u vs. 13.53. "nConclusion: Maternal insulin resistance is associated with the accumulation of maternal fat tissue during early stages of pregnancy and greater fetoplacental nutrient availability in later stages, when 70% of fetal growth occurs, resulting in macrosomia.

    FXF is a third-generation antihistamine drug and osthole is assumed a natural antihistamine alternative. This paper compares peripheral blood mononuclear cell (PBMC) incubation with FXF and osthole, by studying FXF, osthole and histamine cytokine secretion in PBMC in vitro cultures. Mabtech kits determined the interleukins IL-1β, IL-4, IL-10, IL-13 and TNF-α. The influence of the above active substances on cytokine secretion in PBMC's and serum was assessed: cytokines were IL-1β, IL-4, IL-10, IL-13 and TNF-α; and cytokine levels secreted by untreated PBMCs in pure culture medium formed the absolute control (ctrl). We determined that osthole affects PBMC cytokine secretion to almost precisely the same extent as FXF (IL-1β, IL-4, IL-10 and TNF). In addition osthole had greater IL-13 blocking ability than FXF. Moreover, we observed significantly decreased IL-4 level in histamine/osthole theatment compared to histamine alone. Meanwhile, FXF not significantly decrease the level of IL-4 increased by histamine. This data indicates osthole's strong role in allergic inflamation. All results confirm our hypothesis that osthole is a natural histamine antagonist and therefore can be beneficially used in antihistamine treatment of conditions such as allergies.

    Full Text Available To examine the association of serum leptin level with anemia in hemodialysis, we investigated 36 patients (males: 21, diabetics: 11 under regular hemodialysis. For patients, complete blood counts, iron profile, serum leptin, and adequacy of hemodialysis were assessed. In this study a significant correlation of serum leptin with level of hemoglobin and body mass index was detected. An association between serum leptin and total iron binding capacity was observed. No correlation of serum ferritin with leptin level was seen. Our findings attest previous findings showing that greater serum leptin levels are associated with greater hemoglobin levels.

    Previous studies have indicated that autoimmune diseases might be caused by an imbalance of T helper cells (Th), cytokines, and regulatory T cells (Treg) cytokines. We measured the plasma concentrations of Th1-associated cytokines (IFN-gamma, IL-2), Th2 -associated cytokines (IL-4, IL-10), Th17-associated cytokine (IL-17) and Treg -associated cytokine (TGF-beta1) in adult patients with immune thrombocytopenia (ITP) and evaluated their clinical relevance. Plasma IFN-gamma, IL-2, IL-4, IL-10, IL-17 and TGF-beta1 concentrations of 52 ITP patients and 30 age- and sex-matched healthy controls were measured by enzyme-linked immunosorbent assay method (ELISA). Concentration of Th2 cytokines (IL-4 and IL-10) were significantly higher in ITP patients compared to controls (P cytokines (IFN-gamma, IL-2), Th17 cytokine (IL-17) and Treg cytokine (TGF-beta1) were lower in ITP patients (P cytokine concentration among the other subgroups in ITP patients was found. Among the ITP patients, concentration of IFN-gamma correlated positively and significantly with PAIgG (r = 0.48, P = 0.02). A significant correlation was neither found between other cytokine levels and platelet count, nor between cytokine levels and megakaryocytes number, nor between cytokines levels and PAIgG or GPIIb/IIIa and/or GPIb/IX autoantibodies. The present study demonstrates that an imbalance of Th and Treg cytokines may mediate the pathogenesis of ITP.

    Full Text Available Background and Design: Interleukin-23 (IL-23 is a cytokine which is believed to have an important role in the pathogenesis of autoimmune diseases. Therefore, it can be used as a target molecule in the treatment of autoimmune diseases. The aim of our study was to determine serum IL-23 levels in patients with vitiligo to understand their possible roles in the disease etiology and to compare the results with the healthy controls. Materials and Methods: Fifty-one patients, who applied to the dermatology outpatient clinic and were diagnosed with vitiligo clinically and by wood lamp inspection, were enrolled in our study. Thirty-six age- and sex-matched healthy subjects were also enrolled as the control group. Serum IL-23 levels were studied in peripheral venous blood samples. Statistical analyses were made by SPSS version 16.0 for Windows. Results: Vitiligo group and control group were similar in terms of age and sex. Generalized type vitiligo was detected in 27 (52,9%, whereas focal, acrofacial, segmental and universal forms were detected in 13 (25,5%, 5 (9,8%, 3 (5,9% and 3 (5,9% of the patients, respectively. Mean serum IL-23 values were not significantly different between patient and control group (p=0.606. We also showed that serum IL-23 levels did not show any statistically significant difference in patients according to the size of the body surface area involved, involvement of the anogenital area, clinical manifestation, duration of disease and gender respectively (p=0.904, p=0.335, p=0.354, p=0.317, p=0.729, respectively. Conclusions: To our knowledge, this is the first study investigating IL-23 levels in vitiligo. According to our findings, IL-23 level was not higher in vitiligo patients. Because of the small number of subjects involved in our study, further studies involving larger groups are needed to verify our results in IL-23 levels in vitiligo patients.

    Objective To detect cytokines levels in serum and dendritic cells (DCs)-derived supernatans in MCF-7 mice in order to provide a basis for immunotherapy. Methods The levels of tumor necrosis factor-a (TNP-α) > interleukin (ID-6 and IL-12 were detected serum and DCs-derived supernatans with ELISA in 10 MCF-7 mice (tumor-bearing mice) and 10 nude mice. Results The level of TNF-a in serum was (314. 81 ± 103. 36) pg/mL in tumor-bearing mice and (371. 87 + 115. 30) pg/mL in nude mice, which showed no significant difference (P>0. 05). And the level of TNF-a in DCs-derived supernatans was (1. 88 + 0. 10)ng/mL in tumor-bearing mice and (1. 72 + 0. 07) ng/mL in control mice, which showed a significant difference (P<0. 05). The IL-6 levels in serum and DCs-derived supernatans were (170. 72 + 54. 51) pg/mL and (57. 18 + 5. 06) pg/mL in tumor-bearing mice, significantly higher than those in nude mice ((122.35+20. 65) pg/mL and (44. 53 + 4. 86) pg/mL) (P<0.05). The IL-12 levels in serum and DCs-derived supernatans were (119. 80 + 33. 53) pg/mL and (89. 76 + 8. 89) pg/mL in tumor-bearing mice, significantly lower than those in nude mice ((186. 22 + 51. 91) pg/mL and (157. 98 + 48. 31) pg/mL) (P<0. 05). Conclusion IL-6 in serum may participate breast cancer cell growth in MCF-7 tumor-bearing mice. DCs may participate producing TNF-a, promoting the secretion of IL-6 and inhibiting the secretion of IL-12, and may decrease the ability of killing tumor cell.%目的 探讨MCF-7荷瘤小鼠模型血清和树突状细胞(dendritic cells,DCs)上清液中细胞冈子水平的变化,为免疫治疗提供依据.方法 裸鼠(对照组)及MCF-7裸鼠模型(荷瘤组)各10只,应用ELISA法检测血清及DCs上清液中肿瘤坏死因子(tumor necrosis factor,TNF)-α、白细胞介素(interleukin,IL)-6、IL-12水平.结果 荷瘤组血清TNF-α水平((314.81±103.36)pg/mL)低于对照组((371.87±115.30) pg/mL),但2组比较差异无统计学意义(P>0.05),DCs

    Full Text Available Multiplexing arrays increase the throughput and decrease sample requirements for studies employing multiple biomarkers. The goal of this project was to examine the performance of Multiplex arrays for measuring multiple protein biomarkers in saliva and serum. Specimens from the OsteoPerio ancillary study of the Women's Health Initiative Observational Study were used. Participants required the presence of at least 6 teeth and were excluded based on active cancer and certain bone issues but were not selected on any specific condition. Quality control (QC samples were created from pooled serum and saliva. Twenty protein markers were measured on five multiplexing array panels. Sample pretreatment conditions were optimized for each panel. Recovery, lower limit of quantification (LLOQ and imprecision were determined for each analyte. Statistical adjustment at the plate level was used to reduce imprecision estimates and increase the number of usable observations. Sample pre-treatment improved recovery estimates for many analytes. The LLOQ for each analyte agreed with manufacturer specifications except for MMP-1 and MMP-2 which were significantly higher than reported. Following batch adjustment, 17 of 20 biomarkers in serum and 9 of 20 biomarkers in saliva demonstrated acceptable precision, defined as <20% coefficient of variation (<25% at LLOQ. The percentage of cohort samples having levels within the reportable range for each analyte varied from 10% to 100%. The ratio of levels in saliva to serum varied from 1∶100 to 28∶1. Correlations between saliva and serum were of moderate positive magnitude and significant for CRP, MMP-2, insulin, adiponectin, GM-CSF and IL-5. Multiplex arrays exhibit high levels of analytical imprecision, particularly at the batch level. Careful sample pre-treatment can enhance recovery and reduce imprecision. Following statistical adjustments to reduce batch effects, we identified biomarkers that are of acceptable quality in

    Interleukin-6 (IL-6) is a key pro-inflammatory cytokine involved in different physiologic and pathophysiologic processes, and circulating levels of IL-6 differ greatly between individuals. The Chinese Hui is one of the largest ethnic minorities, little is known about the distribution of IL-6 genetic variations and their effects on serum levels in Hui population. The aim of the present study is to determine the prevalence of -174G/C (rs1800795), -597G/A (rs1800797), and -634C/G (rs1800796) polymorphisms in the IL-6 gene promoter region and their association with IL-6 serum levels in the Ningxia Hui population. A total of 96 Hui subjects, (57 men and 39 women; mean age 49.65 ± 19.73 years) unrelated nationality residents in Ningxia Hui Autonomous Region were enrolled. Genotyping of the three polymorphisms were performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) combined with gel electrophoresis and then confirmed by direct sequencing. The -174G/C (97.92% GG, 2.08% GC, and 0% CC) and -597G/A (98.96% GG, 1.04% GA, and 0% AA) polymorphisms were rare. The frequencies of -634C/G genotypes CC, CG, and GG were found to be 54.17%, 40.62%, and 5.21%, respectively in total studied subjects, the derived allele frequencies for the C and G alleles were 74.48% and 25.52%. Increased IL-6 levels were correlated with the IL-6 -634G allele carriers (CG+GG genotypes). The results suggest that IL-6 -174G/C and -597G/A are rare but -634C/G is common in the Ningxia Hui population, and the -634G allele is associated with circulating levels of IL-6.

    To evaluate (18)F-fluorodeoxyglucose ((18)F-FDG) uptake on positron emission tomography-computed tomography (PET-CT) and serum levels of different cytokines and matrix metalloproteinases (MMPs) in patients with Takayasu arteritis (TA) and associations with disease activity. Serum levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-2, IL-6, IL-8, IL-12, IL-18, MMP-3 and MMP-9 were measured in 36 TA patients and 36 controls. Maximum standard uptake value (SUVmax) of (18)F-FDG in arterial walls was determined by PET-CT scans. TA patients were classified as active disease, inactive disease and possible active disease. Serum IL-6 and MMP-3 levels were higher in TA patients than in controls (p<0.001). Serum IL-6 was higher in patients with active disease and in patients with possible active disease than in inactive disease (p<0.0001). Patients with active disease had higher serum TNFα levels than patients with inactive disease (p=0.049) while patients with possible active disease presented higher IL-18 levels than patients with inactive disease (p=0.046). Patients with active disease had higher SUVmax values than those with inactive disease (p=0.042). By receiver operating characteristic (ROC) curve SUVmax was predictive of active disease in TA and values ≥1.3 were associated with disease activity (p=0.039). Serum TNF-α levels were higher in patients with SUVmax≥1.3 than <1.3 (p=0.045) and controls (p=0.012). Serum IL-6 levels were higher in patients with SUVmax≥1.3 than in controls (p<0.001). No differences regarding other biomarkers were found between TA patients and controls. Higher serum IL-6 and TNFα levels as well as higher (18)F-FDG uptake in arterial wall are associated with active TA. Copyright © 2015 Elsevier Editora Ltda. All rights reserved.

    Objective To explore changes of serum cytokines, cortisol (Cor) levels and cognitive function of patients with affective disorders in the elderly before and after selective serotonin reuptake inhibitors (SSRIs) treatment.Methods 50 elderly patients with affective disorder ( the patient group) and 45 normal elderly subjects ( the control group) were enrolled. Blood samples were used for determining serum macrophage migration inhibitory factor (MIF) by enzyme linked immunosorbent assay and IL-1β, IL-6 and Cor levels by radioimmunoassay. The patient group was tested by neuropsychology scales before and after SSRIs treatment. Results ① Before treatment, MIF, IL-1β, IL-6 and Cor levels were higher in the patient group than those in the controls and those after treatment(P <0.05). There was a positive correlation( P <0.01 ) of MIF, IL-1β, IL-6 and Cor levels with the score of the 24 item Hamilton Depression Scale( HAMD24 ) and Pittsburgh sleep quality index (PQSI) . The score of the 14 item Hamilton Anxiety Scale (HAMA14) positively correlated with levels of MIF and IL-6( P < 0. 05 ). ② Patients with affective disorder made improvements in scores of neuropsychological tests after treatment( P <0.01 ). ③ The score in sleeping disturbance symptom was negatively correlated to the improvement in visuospatial and executive ability( r = -0. 251, P <0.01 ), verbal ability(r= -0.326, P<0.01), and delay memory(r= -0. 296, P<0.01), and the score in anxiety/somatization was negatively correlated to the improvement in visuospatial and executive ability ( r = - 0. 204, P < 0.01 ), verbal ability( r = - 0. 398, P < 0.01 ) , abstract( r = - 0. 307, P < 0.01 ) and delay memory( r = - 0. 236, P < 0.05 ). Conclusion Increasing of serum cytokines and Cor levels in patients with affective disorder in the elderly is related to the severity of anxiety and depression. SSRIs can inhibit expressions of inflammatory factors to improve cognitive function of patients

    The present study aimed at profiling inflammatory cytokines for neurological and psychiatric diseases. A total of 86 patients with meningitis, multiple sclerosis, tension-type headache, idiopathic facial nerve palsy (IFNP), affective and schizophrenic disorders were tested for both, serum and cerebrospinal fluid (CSF) using a multiplexed cytokine ELISA for IFN-γ, TNF-α, IL-1β, IL-2, IL-4, IL-5, IL-8/CXCL8, IL-10, IL12p70, IL-13 and IL-17. Cases with viral and bacterial meningitis had unequivocally higher cytokine concentrations in the CSF when compared with serum. Bacterial meningitis was unique by extremely elevated IL-17, TNF-α and IL-1β, indicating a plethora of inflammatory pathways, selectively activated in the CSF. In relapsing multiple sclerosis, IFN-γ and IL-10 were elevated in both, serum and CSF, but IL-12p70, IL-5, IL-13, and TNF-α were more prominent in serum than in CSF. Qualitatively similar biomarker patterns were detected in patients with idiopathic facial nerve palsy and tension-type cephalgia. Affective and schizophrenic disorders clearly present with an inflammatory phenotype in the CSF and also serum, the cytokines determined were in general higher in schizophrenia. Except IFN-γ, schizophrenic patients had higher IL-12p70 and a trend of higher IL-10 and IL-13 in serum suggesting a more prominent TH2-type counter regulatory immune response than in affective disorders. These differences were also mirrored in the CSF. Elevated IL-8 appears to be the most sensitive marker for inflammation in the CSF of all diseases studied, whereas TNF-α was restricted to peripheral blood. With the exception of IL-8, all but viral and bacterial meningitis, studied, displayed higher means of elevated lymphokine concentrations in the serum than in the CSF. This observation supports the concept of immunological crosstalk between periphery and intrathecal immunity in neurological and psychiatric diseases.

    This study was designed to assess alterations of hormone and cytokine levels associated with growth period during puberty in Honamlı goats which were identified as a new goat breed and had one of the highest meat production potential among the other goat breeds in Turkey. Honamlı goats are originated from native hair goats, so parallel studies of sampling and analyzing were conducted also in native hair goats which have moderate meat production. Blood serum samples of Honamlı (n=90) and native hair goats (n=90) were obtained from the pure herds in Korkuteli and Ka districts of Anatolia. Concentrations of growth hormone (GH), myostatin (MSTN), insulin-like growth factor (IGF), growth hormone releasing hormone (GHRH), growth hormone releasing peptide (GHRP), leptin, transforming growth factor-betal (TGF-β1) and vascular endothelial cell growth factor (VEGF) levels were measured by ELISA in each breed in the age groups of 4, 8 and 12 months. The present results indicate interesting correlations among the age groups and all the examined hormone and cytokine parameters exhibited significant (Phormonal alterations of goats could occur at 4th month of age. The results reported here emphasize the primary role played by GH, MSTN, IGF-1, leptin, GHRH, GHRP, TGF-βi and VEGF in the first year growth period of goats.

    A growing body of evidence is pointing toward an association between immune molecules, as well brain-derived neurotrophic factor (BDNF) and the depression. The present study was aimed to evaluate the behavioral and molecular effects of the antidepressant imipramine in maternally deprived adult rats. To this aim, maternally deprived and non-deprived (control group) male rats were treated with imipramine (30mg/kg) once a day for 14 days during their adult phase. Their behavior was then assessed using the forced swimming test. In addition to this, IL-10, TNF-α and IL-1β cytokines were assessed in the serum and cerebrospinal fluid (CSF). In addition, BDNF protein levels were assessed in the prefrontal cortex, hippocampus and amygdala. In deprived rats treated with saline was observed an increase on immobility time, compared with non-deprived rats treated with imipramine (pimipramine treatment reversed the effects of maternal deprivation on BDNF and cytokines levels (pimipramine, it is suggested that classic antidepressants could exert their effects by modulating the immune system.

    Full Text Available Objectives: Resistin, a hormone secreted from adipocytes and considered to be a likely cause of insulin resistance, has recently been accepted as a proinflammatory cytokine. This study aimed to determine the correlation between resistin levels in patients with intra-abdominal sepsis and mortality. Methods: Of 45 patients with intraabdominal sepsis, a total of 35 adult patients were included in the study. This study was undertaken from December 2011 to December 2012 and included patients who had no history of diabetes mellitus and who were admitted to the general surgery intensive care units of Gazi University and Bülent Ecevit University School of Medicine, Turkey. Evaluations were performed on 12 patients with sepsis, 10 patients with severe sepsis, 13 patients with septic shock and 15 healthy controls. The patients’ plasma resistin, interleukin-6 (IL-6, tumour necrosis factor alpha (TNF-α, interleukin-1 beta (IL-1β, procalcitonin, lactate and glucose levels and Acute Physiology and Chronic Health Evaluation (APACHE II scores were studied daily for the first five days after admission. A correlation analysis of serum resistin levels with cytokine levels and APACHE II scores was performed. Results: Serum resistin levels in patients with sepsis were significantly higher than in the healthy controls (P <0.001. A significant correlation was found between serum resistin levels and APACHE II scores, serum IL-6, IL-1β, TNF-α, procalcitonin, lactate and glucose levels. Furthermore, a significant correlation was found between serum resistin levels and all-cause mortality (P = 0.02. Conclusion: The levels of resistin were significantly positively correlated with the severity of disease and were a possible mediator of a prolonged inflammatory state in patients with intra-abdominal sepsis.

    Vitamin D is a fat-soluble micronutrient that regulates inflammation and skeletal muscle size and function. Inflammation and skeletal muscle dysfunction (i.e., atrophy and weakness) are predominant impairments that continue to challenge the rehabilitation from total knee arthroplasty (TKA). Data suggest a decrease in serum 25-hydroxyvitamin D (25(OH)D) concentrations after TKA. Despite the decrease being attributed to a systemic inflammatory response, it is unclear what inflammatory mediator(s) is contributing to the decrease in serum 25(OH)D concentrations after TKA. In immune cells, pro-inflammatory cytokines mediate the enzymatic conversion of 25(OH)D to 1,25-dihydroxyvitamin D, implying that pro-inflammatory cytokines contribute to the decrease in substrate availability (i.e., 25(OH)D). We propose the hypothesis that pro-inflammatory cytokines mediate the decrease in serum 25(OH)D concentrations after TKA. To complement the supporting literature for the proposed hypothesis, we analyzed serum 25(OH)D and pro-inflammatory cytokine concentrations prior to and serially after TKA in a case subject (female; age, 62 year; height, 160 cm; body mass, 63 kg; body mass index, 26.5 kg/m(2)). The subtle decrease (12%) from pre-surgery to 2-d post-surgery and the more pronounced decrease (74%) from 3-week to 8-week post-surgery in serum 25(OH)D concentrations corresponded with the increase in serum pro-inflammatory cytokine (i.e., TNF-α, IFN-γ, IL-1β, GM-CSF, and IL-6) concentrations. This observation lends credence to the proposed hypothesis that pro-inflammatory cytokines could contribute to the decrease in serum 25(OH)D concentrations after TKA. Clearly, future research is needed to confirm the proposed hypothesis and to identify if attenuating the decrease in serum 25(OH)D concentrations improves patient outcomes after TKA.

    We thought that dioxin and dioxin-like compound receptor AhR expressed on the surface of regulatory T (Treg) cells and Th17 cells could regulate immunological functions in the Yusho patients. In the present study, we measured Treg cell related cytokines IL-10 and IL-35 in the Yusho patients. Serum levels of IL-10 were higher, but not significant (p = 0.06), and serum levels of IL-35 were increased (p = 0.006) in comparison with healthy controls. These results imply Treg cell activation in the Yusho patients.

    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.

    Full Text Available Inflammation persists in patients infected with HIV. Reduction of inflammatory cytokines and microbial translocation might be one way that this could be managed. Purpose: The anti-inflammatory properties of certain probiotic strains prompted us to investigate whether a probiotic could reduce the inflammatory index of HIV-infected patients. Methods: The study involved 30 HIV+ males on antiretroviral therapy, who were given one bottle of fermented milk Yakult Light® containing Lactobacillus casei Shirota (LcS twice a day for four weeks. Results: The probiotic LcS was associated with an increase of T lymphocytes and a significant increase of CD56+ cells (p = 0.04. There was also a significant decrease of mRNA levels of TGFβ, IL-10 and IL-12 (p < 0.001 and IL-1β expression (p < 0.001 and an increase of serum IL-23 (p = 0.03. In addition, decreased inflammation and cardiovascular risk were observed, as shown by a reduction of cystatin C (p < 0.001. Conclusions: These data provide preliminary evidence that probiotic supplementation may modulate certain immunological parameters and some of the cytokines that were analyzed. Thus, we propose that LcS may be an inexpensive and practical strategy to support the immune function of HIV+ patients.

    The aim of this study is to evaluate proinflammatory and anti-inflammatory cytokine levels in gingival crevicular fluid (GCF) and serum of rheumatoid arthritis (RA) and chronic periodontitis (CP) patients to assess whether cytokine profiles distinguish patients with RA and patients with CP while using healthy patients as background controls. A total of 49 patients, 17 patients with RA (three males and 14 females; mean age: 47.82 ± 10.74 years), 16 patients with CP (10 males and six females; mean age: 44.00 ± 7.00 years), and 16 controls (eight males and eight females; mean age: 28.06 ± 6.18 years) were enrolled. Patients with RA were under the supervision of rheumatologists; 15 of the patients with RA were being treated with methotrexate-sulfasalazine combined therapy, and two of the patients were being treated with leflunomid therapy. Periodontal parameters (plaque index, gingival index, probing depth, and clinical attachment level) were recorded. Interleukin (IL)-1β, IL-4, IL-10, and tumor necrosis factor-α (TNF-α) were determined in GCF and IL-1β and IL-10 in serum by enzyme-linked immunosorbent assay. There were significant differences found among RA, CP, and control groups for all periodontal parameters (P 0.05). Although the total amount and concentration of serum IL-10 was not significantly different among the groups (P >0.05), serum IL-1β was significantly lower in the RA group compared to CP patients and controls and was higher in GCF of the RA group compared to the CP group. Although clinical periodontal disease parameters indicated more severe periodontal disease in CP compared to RA patients, immunologic evaluation did not reveal consistent results regarding proinflammatory and anti-inflammatory cytokine levels. This might be a result of the use of non-steroidal anti-inflammatory drugs and rheumatoid agents by patients with RA.

    Full Text Available Background: Rheumatoid arthritis (RA is a chronic, systemic, inflammatory disease with autoimmune etiology, characterized by synovial inflammation and destruction of joint cartilage and bone. There are controversial data about the profile of interleukin-17 (IL-17A, interleukin-4 (IL-4, and interferon-gamma (INFγ, indicating in some studies the key role of IL-17, while in others the Th1 cytokines. Materials and Methods: Serum samples of 31 early RA patients were evaluated for erythrocytes sedimentation rate (ESR, rheumatoid factor (RF, C-reactive protein (CRP, anti-cyclic citrullinated peptide antibodies (anti-CCP, and for the tested cytokines (IL-17A, IL-4, and INFγ. Disease activity score (DAS28 calculation was done for all patients. Control serum samples were obtained from 29 healthy volunteers. Results: The levels of tested cytokines were significantly higher (IL-17A, p < 0.001; INFγ, p < 0.001; IL-4, p < 0.01 in patients with early RA, compared to the healthy controls. In early RA patients, a strong correlation of serum IL-17A was found with DAS28, ESR, and CRP. Also, significant negative correlation was found between serum INFγ levels and the DAS28 score, indicating that INFγ may play a key role in maintaining immune homeostasis in patients with RA. Conclusion: The mean serum IL-17A levels in patients with early RA, corresponded with the disease activity and severity. This might highlight the usefulness of the serum IL-17A level in defining the activity and predictive patterns, for aggressive disease therapy, and it might express specific therapeutically targets.

    Full Text Available In­tro­duc­ti­on: Atopic dermatitis (AD is associated with an imbalance between T helper 1 (Th1 and T helper 2 (Th2 cells. It is chronic relapsing inflammatory skin disease affecting especially the children. Recently, it has been intensively studied and new aspects regarding the immunopathogenesis are suggested. Studies about the role of cytokines on formation of atopic diseases are rather new and most of them are based on in vitro observations. It is not completely clear yet how cytokines regulate diseases in vivo and studies about this subject are rather limited. In this study; the serum levels of IL-8, TNF-α, IL-6 and the relationship between these parameters and the disease severity in a group of children with AD were investigated.Materials and Methods: The severity of AD was assessed by the same dermatologist using the Scoring Atopic Dermatitis (SCORAD index system. IL-8, TNF-α, and IL-6 levels were measured by ELISA method.Results: Serum levels of IL-8, TNF-α and IL-6 were determined and were found statistically significantly higher in patients than controls. A statistically significant correlation between serum levels of IL-8, TNF-α, and IL-6 and SCORADs in children with AD was determined.Conclusion: These results show that serum levels of IL-8, TNF-α, and IL-6 may be used as important markers in the assessment of disease severity and follow-up of child patients with AD. As a result, the role of cytokines and the relationship between cytokines in the immunopathogenesis of AD are rather complex and still not clearly clarified, further investigations are required to understand this complex process.

    Trichomoniasis, the most common non-viral sexually transmitted disease, is caused by infection with the protist Trichomonas vaginalis. The clinical spectrum varies from an asymptomatic to a severe symptomatic state. However, the exact factors leading to varied symptomatology have not been well elucidated. The role of cytokines in the pathogenesis of many microbial diseases has been reported. The present study reports the cytokine levels (IL-2, IL-4, IFN-gamma) on different days post infection (3rd, 7th, 14th, 21st and 28th d.p.i.) in serum and vaginal washes (VWs) of mice infected intravaginally with T. vaginalis isolates from 15 symptomatic and 15 asymptomatic women. Significantly higher production of IL-2 and IFN-gamma was observed on the 3rd to 28th d.p.i., and IL-4 on the 7th to 21st d.p.i., in infected as compared to uninfected mice. A significant increase in cytokine IL-2 and IFN-gamma was observed on the 3rd to 28th d.p.i. in serum and VWs of mice infected with T. vaginalis isolates from asymptomatic as compared to symptomatic women. IL-2 (P < 0.001) and IFN-gamma (P < 0.05) concentrations were significantly higher on the 14th d.p.i. in serum samples as compared to VWs of mice infected with T. vaginalis isolates from asymptomatic and symptomatic women, while no significant difference was observed in IL-4 concentration between the two groups of mice. The study indicates the involvement of a Th-1 (IL-2 and IFN-gamma) like response in mice infected with isolates from asymptomatic women as compared to symptomatic women and suggests that Th-1 type cytokines might be playing a role in maintaining low levels of infection.

    Intimate partner violence (IPV) is a public health concern, affecting one-third of US women. Prior research suggests an association between exposure to IPV and poor maternal perinatal health, but the underlying biological correlates are not well understood. This study examined the relationship between exposure to IPV and proinflammatory cytokine levels, a candidate mechanism accounting for poor psychiatric and obstetric outcomes, across the perinatal period. Data were obtained from a prospective, longitudinal cohort study of 171 women receiving obstetrical care from a hospital-based practice serving a predominantly low-income minority population. Participants completed questionnaires on IPV exposure, psychiatric symptoms, and psychosocial and obstetric factors and provided blood samples at 18 and 32 weeks of gestation and 6 weeks and 6 months postpartum. Serum levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were assayed via enzyme-linked immunosorbent assay. Thirty-five (20.5%) women reported lifetime exposure to IPV and 7 (4.1%) reported being physically hurt in the preceding 12 months (4 while pregnant). Lifetime exposure to IPV was associated with increased likelihood of experiencing perinatal depression and smoking during pregnancy. Women with a history of IPV had significantly higher levels of TNF-α at 18 weeks (z = -2.29, p < 0.05), but significantly smaller changes in levels of IL-6 (β = -0.36, p = 0.04) across time. Lifetime exposure to IPV was associated with a range of adverse mental health outcomes and may affect proinflammatory cytokine levels in pregnancy.

It results from chronic inflammation and causes irreversible airway damage. Levels of different serum cytokines could be surrogate biomarkers for inflammation and lung function in COPD. We aimed to determine the serum levels of different biomarkers in COPD patients, the association between cytokine levels and various prognostic parameters, and the key pathways/networks involved in stable COPD. In this study, serum levels of 48 cytokines were examined by multiplex assays in 30 subjects (control, n=9; COPD, n=21. Relationships between serum biomarkers and forced expiratory volume in 1 second, peak oxygen uptake, body mass index, dyspnea score, and smoking were assessed. Enrichment pathways and networks analyses were implemented, using a list of cytokines showing differential expression between healthy controls and patients with COPD by Cytoscape and GeneGo Metacore™ softwares (Thomson-Reuters Corporation, New York, NY, USA. Concentrations of cutaneous T-cell attracting chemokine, eotaxin, hepatocyte growth factor, interleukin 6 (IL-6, IL-16, and stem cell factor are significantly higher in COPD patients compared with in control patients. Notably, this study identifies stem cell factor as a biomarker for COPD. Multiple regression analysis predicts that cutaneous T

    Full Text Available Hashimoto's thyroiditis (HT is an organ-specific, mainly Th1 autoimmune disorder. New evidence has accumulated for involvement of Treg-produced cytokines. Interleukin (IL-12 and IL-10 are immunoregulatory cytokines with antagonistic effect on Th differentiation. This study was designed to investigate the correlation of circulating IL-10 and IL-12p40 with their genotypes in 124 HT patients in different stages of disease. The IL-10 and IL-12p40 circulating level in the serum of HT patients and healthy controls was determined by enzyme-linked immunosorbent assay. Genotyping for the 3’UTR A/C IL12B polymorphism was performed using restriction fragment length polymorphism–polymerase chain reaction and genotyping for −1082 A/G by amplification refractory mutation system (ARMS-PCR. The results showed significantly enhanced IL-12p40 serum quantity both in euthyroid and hypothyroid stages compared to controls and insignificantly decreased level after levothyroxine treatment. Regarding the 3’UTR A/C IL12B polymorphism, a significantly higher frequency of the AA genotype was observed in HT patients than in healthy individuals. The serum IL-10 level was significantly increased in hypothyroid HT patients compared to controls and euthyroid patients. Stratification based on the −1082 A/G polymorphism revealed a significantly enhanced level of circulating IL-10 in hypothyroid patients with a GG genotype compared to AA and AG genotypes. There were also significant differences between the circulating IL-10 quantity in hypo- and euthyroid patients with GG genotypes. In conclusion, the IL-12p40 and IL-10 serum level in HT patients was dependent on the genotype and HT stages, suggesting that enhanced IL-10 serum level in combination with enhanced IL-12p40 is associated with hypothyroidism in HT development.

    Full Text Available This study assessed the number of CD4 T lymphocytes, the parasitemia and serum levels of interferon gamma (IFN-gamma, tumor necrosis factor alpha (TNF-alpha, interleukin-1 (IL-1, IL-4 and IL-10 of patients infected by human immunodeficiency virus (HIV and human immunodeficiency virus/Chagas' disease coinfection. CD4 T lymphocytes were low in the two groups of patients, although significantly lower in patients without Chagas' disease. Serum levels of IFN-gamma, IL-4 and TNF-alpha were significantly higher in patients with HIV/Chagas' disease. IL-4/IFN-gamma ratios were higher in patients with HIV/Chagas' disease, which showed a clear balance in favor of Th2-like cytokines in this group of patients. This Th2 balance was higher in patients with detectable parasitemia. We conclude that, although immunosuppression was observed, with CD4 T lymphocytes bellow 200/µm³, these patients did not display reactivation of T. cruzi infection and that a balance favorable to Th2 was associated with the presence of parasitemia.Neste estudo foi avaliado o número de linfócitos TCD4, a parasitemia e os níveis séricos de interferon gama (IFN-gama, fator de necrose tumoral alfa (TNF-alfa, interleucina-1 (IL-1, IL-4 e IL-10 em pacientes infectados pelo vírus da imunodeficiência adquirida ou apresentavam co-infecção pelo HIV/Trypanosoma cruzi.

    Abstract Recent studies demonstrated an adverse effect of chronic exposure to air pollution (AP) on metabolic syndrome and its components. In a population-based study, we investigated the association between exposure to ambient AP and serum glucose (SG), among subjects with normal glucose, impaired fasting glucose (IFG), and diabetes mellitus (DM). We included 1,063,887 SG tests performed in 131,882 subjects (years 2001–2012). Exposure data included daily levels of SO2, NO2 and other pollutants of industrial, traffic, and nonanthropogenic sources. Demographical, clinical, and medications purchase data were assessed. Log-transformed SG levels were analyzed by linear mixed models adjusted for seasonal variables and personal characteristics. SG increases (%increase [95% CI]), among subjects with normal glucose, IFG, and DM, respectively, were associated with 6.36 ppb increase of NO2 measured 24 to 72 hours before the test (0.40% [0.31%; 0.50%], 0.56% [0.40%; 0.71%], and 1.08% [0.86%; 1.29%]); and with 1.17 ppb increase of SO2 measured 24 hours before the test (0.29% [0.22%; 0.36%], 0.20% [0.10%; 0.31%], and 0.33% [0.14%; 0.52%]). Among DM population, weakest association was observed among patients treated with Metformin (0.56% increase in SG [0.18%; 0.95%]). In conclusion, NO2 and SO2 exposure is associated with small but significantly increased levels of SG. Although DM patients were found to be more susceptible to the AP induced SG variations, Metformin treatment seem to have a protective effect. Given the chronic lifetime exposure to AP and the broad coverage of the population, even small associations such as those found in our study can be associated with detrimental health effects and may have profound public health implications.

    Introduction Preeclampsia and HIV/AIDS are inflammatory conditions that contribute significantly to adverse maternal and foetal outcomes. The immune reconstitution effects of HAART on inflammatory mediators has not been adequately studied in pregnancy and may impact on the inflammatory cytokine network in women with co-morbid preeclampsia. Our study evaluated changes in pro-inflammatory cytokines IL-2, TNF-α, IFN-γ and IL-6 in HIV infected preeclamptic women on HAART. Methods A prospective experimental study was conducted at Prince Mshiyeni Memorial Hospital between July 2013 and September 2014. One hundred and ninety three pregnant women were recruited into 4 groups: uninfected normotensive (50; 26%), infected normotensive (45; 23%), uninfected preeclamptic (53; 28%) and infected preeclamptic women (45; 23%). Serum levels of cytokines TNF-α, IFN- γ, IL-2 and IL-6 were determined using commercially available kits and a Cytometric Bead Array (CBA). Comparative data was recorded and analysed descriptively. Results In the control groups (normotensive), significantly lower values were found in IL-2 (p = 0.010), TNF-α (p = 0.045), and IL-6 (p = 0.005); and a non-significant decrease was observed in IFN-γ (p = 0.345) in HIV infected women on HAART compared to uninfected controls. In the experimental group (preeclamptic) women, significantly reduced levels were observed in IL-2 and TNF-α (p = 0.001; p = 0.000) and non-significant decreases were observed in IFN-γ and IL-6 (p = 0.023; p = 0.086) in HIV infected women on HAART compared with uninfected preeclamptic women. Non-significant differences were observed between uninfected preeclamptic and normotensive women. Conclusion In uncomplicated/normotensive pregnancies, HIV/HAART is associated with significant decreases in IL-2, TNF-α and IL-6, and in preeclamptic women significant decreases in IL-2 and TNF-α were observed. These findings suggest that HIV/HAART impacts on pro-inflammatory cytokines in women with co

    Objective:To explore the effect of T cell subset and inflammatory cytokine levels on the prognosis in patients with pulmonary tuberculosis.Methods:A total of 72 patients confirmed with pulmonary tuberculosis who were admitted in our hospital from February, 2013 to February, 2015 were included in the study and served as the experiment group, among which 58 cases had active tuberculosis, and 14 cases had static tuberculosis; while 50 healthy individuals who came for physical examinations were served as the control group. The sputum bacteria before treatment and 6 months after treatment in the two groups were detected. The sputum negative conversion rate was recorded. The absorption of pulmonary lesions and the closure of tuberculosis cavity were examined. The immune cell function of T cell subset was detected again.Results: The peripheral blood CD3, CD4, CD8, and CD4/CD8 levels in the experiment group were significantly lower than those in the control group, especially for the active tuberculosis patients (P<0.01). The peripheral blood CD4/CD8 levels in the static tuberculosis patients was lower than that in the control group, but was significantly higher than that in active tuberculosis patients (P<0.01). The serum IL-1, IL-6, and TNF-α levels in the experiment group were significantly higher than those in the control group, especially for the active tuberculosis patients (P<0.01).Conclusions:The cell subsets and inflammatory cytokines play an important role in patients with pulmonary tuberculosis, whose dynamic change can effectively display the immune function and severity degree, which is of great value in estimating the condition and assessing the prognosis; therefore, it deserves to be further explored in the clinic.

    Little is known about cimicosis, the resultant dermal reaction from feeding activity by the common bedbug, Cimex lectularius L. We fed C. lectularius on human study subjects four times over four weeks and measured serum cytokine and antibody levels, and subjects recorded any cimicosis. The average time for subjects to develop cimicosis decreased with each feeding from 8.4, to 2.1, 1.5 and 1.3 days, respectively. There were no significant changes in total IgG, IgG1, IgG2, IgG4 or IgE levels between the first and fourth bedbug feedings, but there was a significant decrease in total IgG3 levels (Plectularius feeding. Lower post-C. lectularius feeding IL-6 levels were associated with increased pruritis (P=.001) and the time to maximum pruritis (P=.04), respectively. Higher post-C. lectularius feeding IL-5 levels were associated with a longer duration of pruritis (P=.05).

    BACKGROUND: Abdominal aortic aneurysm (AAA) is characterized by inflammatory cell accumulation in AAA lesions that produce inflammatory cytokines and advance its pathogenesis. Peripheral cytokines may predict the degree or risk of AAA. METHODS AND RESULTS: ELISA determined plasma interleukin-6 (IL6......), IL10, IL17A, IFN-γ, and C-reactive protein (CRP) from 476 AAA patients and 200 controls. AAA patients had lower IL6, IFN-γ, IL10, IL17A, and higher CRP than controls. IL10 correlated positively with IFN-γ, IL17A, or IL6, but not CRP in control or AAA populations. IL10 associated negatively...... with systolic blood pressure, whereas CRP associated positively with diastolic blood pressure and body mass index. CRP was an independent AAA risk factor and correlated positively with aortic diameters before and after adjustments for other risk factors. IFN-γ, IL17A, and CRP correlated positively with cross...

    Reduced T cell, granulocyte, NK and monocyte function have all been reported following both long and short duration spaceflight, however these data indicate crews are generally not experiencing inflammatory or adaptive immune activation during spaceflight. There appear to be varied individual crew responses, and specific relationships between cytokines and markers of iron status and muscle turnover that warrant further evaluation. Increases in growth factors and chemokines may indicate other types of adaptation occurring during spaceflight, such as attempts to overcome diminished immunocyte function.

    Nutrition plays an important role in immune response. We evaluated the effect of nutrient intake on serum immunoglobulin levels in vegetarian and omnivore children. Serum immunoglobulin levels and iron status were estimated in 22 vegetarian and 18 omnivore children. Seven-day food records were used to assess the diet. There were no significant differences in serum IgA, IgM, and IgG levels between groups of children. Serum immunoglobulin levels were lower in vegetarian children with iron deficiency in comparison with those without iron deficiency. In the vegetarians, IgG level correlated positively with energy, zinc, copper, and vitamin B(6) intake. In the omnivores, these correlations were stronger with IgM level. Despite negligible differences in serum immunoglobulin levels between vegetarian and omnivore children, the impact of several nutrient intakes on IgM and IgG levels differed between groups. Low iron status in vegetarian children can lead to decreased immunoglobulin levels.

Recent studies have demonstrated that serum SP-D concentrations in children are genetically determined and that a single nucleotide polymorphism (SNP) located...... in the NH(2)-terminal region (Met11Thr) of the mature protein is significantly associated with the serum SP-D levels. A classic twin study was performed on a twin population including 1,476 self-reported healthy adults. The serum SP-D levels increased with male sex, age, and smoking status. The intraclass...... correlation was significantly higher for monozygotic (MZ) twin pairs than for dizygotic (DZ) twin pairs. Serum SP-D variance was influenced by nonshared environmental effects and additive genetic effects. Multivariate analysis of MZ and DZ covariance matrixes showed significant genetic correlation among serum...

    The interleukin 12 (IL-12) family plays important roles in autoimmune diseases. To explore the roles of the IL-12 family members IL-27 and IL-35 in the pathogenesis of neuromyelitis optica spectrum disorders (NMOSD), we determined their serum and cerebral spinal fluid levels and assessed potential correlations with clinical characteristics. Serum IL-27 levels were negatively correlated with disease severity and spinal cord lesion length, while serum IL-35 levels were negatively correlated with disease severity and annual relapse rate. Thus, IL-27 and IL-35 may be important biomarkers of NMOSD severity and these molecules might represent potential therapeutic cytokines for treating NMOSD.

    Full Text Available Tumor necrosis factor-like weak inducer of apoptosis (TWEAK, TNFSF12 is a member of the tumor necrosis factor superfamily. TWEAK activates the Fn14 receptor, and may regulate cell death, survival and proliferation in tumor cells. However, there is little information on the function and regulation of this system in prostate cancer. Fn14 expression and TWEAK actions were studied in two human prostate cancer cell lines, the androgen-independent PC-3 cell line and androgen-sensitive LNCaP cells. Additionally, the expression of Fn14 was analyzed in human biopsies of prostate cancer. Fn14 expression is increased in histological sections of human prostate adenocarcinoma. Both prostate cancer cell lines express constitutively Fn14, but, the androgen-independent cell line PC-3 showed higher levels of Fn14 that the LNCaP cells. Fn14 expression was up-regulated in PC-3 human prostate cancer cells in presence of inflammatory cytokines (TNFα/IFNγ as well as in presence of bovine fetal serum. TWEAK induced apoptotic cell death in PC-3 cells, but not in LNCaP cells. Moreover, in PC-3 cells, co-stimulation with TNFα/IFNγ/TWEAK induced a higher rate of apoptosis. However, TWEAK or TWEAK/TNFα/IFNγ did not induce apoptosis in presence of bovine fetal serum. TWEAK induced cell death through activation of the Fn14 receptor. Apoptosis was associated with activation of caspase-3, release of mitochondrial cytochrome C and an increased Bax/BclxL ratio. TWEAK/Fn14 pathway activation promotes apoptosis in androgen-independent PC-3 cells under certain culture conditions. Further characterization of the therapeutic target potential of TWEAK/Fn14 for human prostate cancer is warranted.

    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.

    Full Text Available BACKGROUND: Major Depressive Disorder (MDD is a common disorder, with a lifetime prevalence of about 15 percent, perhaps as high as 25 percent for women. The etiology of MDD is too complex to be explained totally by a single social, developmental, or biological theory. A variety of factors appear to work together to cause or precipitate depressive disorders. Various functions have been reported for trace elements such as zink in recovery or exacerbation of depression. METHODS: In this experimental study, we studied 46 patients with MDD based on DSM IV criteria, among the patients referred to mental disorders clininc of Noor Hospital. Twenty Patients were men and 26 were women. Thirty two volunteers of general population were evaluated for depression with Beck depression test who did not show any depressive symptoms with this test. A blood sample of 5cc was obtained from each person and the serum zinc concentration was measured. Data gathered and analyzed with SPSS, logistic regression and chi-squar tests. RESULTS: Serum zinc concentrations were 74 to 130 mg/dl in men and 60 to 128 mg/dl in women of control group. Serum zinc concentration was 30 to 60 mg/dl in depressive patients that it was lower in women than men. The difference between serum zinc concentrations of normal and depressive persons was meaningful (P = 0.02. CONCLUSION: In our study, the serum concentration of zinc was about half of normal value. This study replicates previous findings that major depressed subjects show significantly lowered serum zinc concentration. KEYWORDS: Depression, zinc.

    Previous studies have shown that cytokines can affect serum lipoprotein concentrations. The aim of this study was to examine the association between IL-10 gene polymorphisms and serum lipoprotein levels of Han Chinese individuals. A total of 359 Han Chinese people were enrolled in this investigation. IL-10 -592, -819, and -1082 genotypes were established using polymerase chain reaction-restriction fragment length polymorphism analysis. An automatic biochemistry analyzer was used to determine serum concentrations of total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very low-density lipoprotein (VLDL) in each individual. We observed that the three IL-10 polymorphisms did not significantly differ in terms of age or age of carrier (P > 0.05), and the -592 and -819 variants did not significantly affect serum lipoprotein levels (P > 0.05). HDL concentrations were higher and TG levels were lower in carriers of the -1082 GA genotype compared to those with the AA genotype, and these differences were statistically significant (P 0.05). Our results suggest that the polymorphism at position -1082 in the promoter region of IL-10 may affect serum HDL and TG concentrations, while other variants of this gene appear to have no relationship with serum lipoprotein levels.

    Objective: This study aimed to determine the serum potassium concentrations in patients with sigmoid volvulus (SV), which is a rare large bowel obstruction. Materials and Methods: The records of 86 patients with SV were reviewed retrospectively, while the records of 41 patients diagnosed with obstructive rectosigmoid cancer (ORC) were considered as the control group and as such, served as a source for comparison. Results: The analysis revealed a mean serum potassium concentration of 3.9 ± 0.6 mEq/L for the patients with SV, while the mean potassium concentration was 3.9 ± 0.5 mEq/L for the patients diagnosed with ORC (t:0.1, P>0.05). The number of hypokalemic and hyperkalemic patients identified in this study sample were 11 versus 5 patients and 1 versus 0 patients, respectively for the SV and ORC groups (x2 = 0.1 and 0.5, respectively with a P>0.05). Conclusions: No cause-and-effect relationship was observed between the serum potassium concentrations and SV. The serum potassium concentration is not pathognomonic for SV. PMID:25610090

    An inadequate and imbalanced intake of protein and energy results in protein-energy malnutrition (PEM). It is known that bone mineral density and serum magnesium levels are low in malnourished children. However, the roles of serum magnesium and endothelin-1 (ET-1) levels in the pathophysiology of bone mineralization are obscure. Thus, the relationships between serum magnesium and ET-1 levels and the changes in bone mineral density were investigated in this study. There was a total of 32 subjects, 25 of them had PEM and seven were controls. While mean serum ET-1 levels of the children with kwashiorkor and marasmus showed no statistically significant difference, mean serum ET-1 levels of both groups were significantly higher than that of the control group. Serum magnesium levels were lower than normal value in 9 (36%) of 25 malnourished children. Malnourished children included in this study were divided into two subgroups according to their serum magnesium levels. While mean serum ET-1 levels in the group with low magnesium levels were significantly higher than that of the group with normal magnesium levels (p malnutrition. Our study suggested that lower magnesium levels and higher ET-1 levels might be important factors in changes of bone mineral density in malnutrition. We recommend that the malnourished patients, especially with hypomagnesaemia, should be treated with magnesium early.

    This study assessed the effects of different selenium (Se) supplementation levels on oxidative stress, cytokines, and immunotoxicity in chicken thymus. A total of 180 laying hens (1 day old; Mianyang, China) were randomly divided into 4 groups (n = 45). The chickens were maintained either on a basic diet (control group) containing 0.2 mg/kg Se, a low-supplemented diet containing 5 mg/kg Se, a medium-supplemented diet containing 10 mg/kg Se, or a high-supplemented diet containing 15 mg/kg Se for 15, 30, and 45 days, respectively. Over the entire experimental period, serum and thymus samples were collected and used for the detection of the experimental index. The results indicated that the antioxidative enzyme activities and messenger RNA (mRNA) levels of antioxidative enzymes, IFN-γ and IL-2 in the thymus, and the content of IFN-γ and IL-2 in the serum of excessive-Se-treated chickens at all time points (except for the 5 mg/kg Se supplement group at 15 days) were significantly decreased (P thymus in the 5 mg/kg Se supplement group at 15 and 30 days compared to the corresponding control groups. In histopathological examination, the thymus tissue from excessive-Se-treated chickens revealed different degrees of cortex drop, incrassation of the medulla, and degeneration of the reticular cells. These results suggested that the excessive Se could result in a decrease in immunity, an increase in oxidative damage, and a series of clinical pathology changes, such as cortex drop, incrassation of the medulla, and degeneration of the reticular cells.

    The objective of this study is to assess the serum IL-35 level and its association with clinical manifestations in patients with systemic sclerosis (SSc). IL-35 serum levels were measured by ELISA from 56 patients with SSc and 53 healthy controls. Association of IL-35 serum levels were sought with clinical parameters. Serum IL-35 levels were significantly higher in SSc patients (5.08 ± 0.76 pg/ml) than in healthy individuals (1.89 ± 0.69 pg/ml; p IL-35 levels than those without fibrosis (7.75 ± 1.36 and 3.08 ± 0.70 pg/ml, respectively, p = 0.0022). IL-35 is elevated in the serum of patients with SSc and is associated with lung fibrosis. Our findings suggest that this cytokine can have a role in fibrotic diseases, but further studies are needed to address the role of IL-35 in the pathogenesis of SSc.

    Full Text Available BACKGROUND Leprosy or hansen’s disease is a spectral disease whose clinical forms mostly depends on host’s immune and genetic factors. Different Toll-like receptors (TLR variants have been described associated with leprosy, but with some lack of replication across different populations. OBJECTIVES To evaluate the role of polymorphisms in genes TLR1, TLR2 and TLR4 and susceptibility to leprosy in a genetic case control study; to verify the association between genotypes of these markers and the immunological profile in the serum of patients with leprosy. METHODS Pre-designed TaqMan® assays were used to genotype markers at TLR1 (rs4833095, rs5743551, TLR2 (rs7656411, rs3804099 and TLR4 (rs1927914, rs1927911. A panel of cytokines and chemokines was accessed by enzime-linked immunosorbent assay (ELISA test in the serum of a subgroup of patients with and without leprosy reactions. FINDINGS Our results show an association between the T allele of rs3804099 at the TLR2 gene and increased risk for leprosy per se [Odds ratio (OR = 1.296, p = 0,022]. In addition, evaluating the association between different genotypes of the TLR1, 2 and 4 markers and cytokine/chemokine serological levels, IL-17 appears as an immunological marker regulated by the polymorphism of the three TLR genes evaluated, whereas different TLR1 genotypes were associated with differential production of IL-12p40 and MCP-1(CCL2. Furthermore, other relevant serum markers such as CXCL-10 and IL-6 seemed to be regulated by TLR2 variants and IL-1β was related to TLR4 genotypes. MAIN CONCLUSIONS All together our data points that the tested TLR markers may have a regulatory role in the immunity against Mycobacterium leprae, by driving the host’s production of key cytokines and chemokines involved in the pathogenesis of this disease.

    A nested, matched case-control study was conducted to assess the relationship between serum levels of copper and the subsequent risk of cancer. One hundred thirty-three cases of cancer were identified during 1974-1984 among 5000 members of a northwest Washington State employee cohort from whom serum specimens had been previously obtained and stored. Two hundred forty-one controls were selected at random from the cohort and were matched to the cases on the basis of age, sex, race, and date of blood draw. Serum copper levels were measured by atomic absorption spectrometry. Risk of a subsequent diagnosis of cancer was positively associated with serum copper levels, but only among those cases diagnosed within 4 years of the time the serum specimens were collected. Among cases diagnosed more than 4 years after specimen collection, there was no consistent association between serum copper levels and risk. Adjustment for age, sex, race, occupational status, cigarette smoking, family history of cancer, alcohol consumption, and, among females, use of exogenous hormones had no appreciable effect on these relationships. The findings suggest that the presence of cancer may increase serum copper levels several years prior to its diagnosis. They are less supportive of the hypothesis that serum copper levels affect cancer risk.

    Context The biology of fatigue and depression in cancer patients is poorly understood. Hypotheses regarding cytokines and growth factors related to sickness behavior and disruption of circadian signaling have been proposed. Objectives We prospectively examined proinflammatory cytokines (e.g., sickness behavior model) and epidermal growth factor receptor (EGFR) ligands (e.g., circadian disruption model) in the serum of cancer patients enrolled in a clinical trial testing levocarnitine for fatigue. Methods Serum samples were collected at baseline and week 4. Cytokine/growth factor analyses were performed with a Luminex analyzer. The Brief Fatigue Index and the Center for Epidemiologic Studies Depression Index were used to measure fatigue and depression severity. The association between cytokine and symptoms was examined using logistic models. Results Among 101 analyzable patients, all ten cytokines/growth factors examined were highly elevated at baseline and all significantly decreased at week 4 (pfatigue significantly increased for patients with higher level of interleukin-1 receptor antagonist (IL-1Ra), whereas patients with higher levels of IL-1Ra, tumor necrosis factor-α, interleukin (IL)-6, IL-8, interferon-γ, transforming growth factor α, and vascular endothelial growth factor had higher odds of severe depression. At week 4, fatigue (p=0.023) and depression (p=0.007) responders had less decrease in IL-1 level than the corresponding non-responders. Conclusion In this correlative analysis of a fatigue clinical trial, levels of fatigue were significantly associated with levels of IL-1 and IL-1Ra. Circadian-signaling pathways related to EGFR signaling were correlated with depression as were other cytokines. A major placebo effect was associated with a global decrease in cytokine and growth factors. These data provide further basis for testing hypotheses regarding the mechanisms of fatigue and depression in cancer patients.

    Full Text Available Osteoprotegerin (OPG wird in der entzündeten Synovialis bei chronischer Polyarthritis von Makrophagen, dendritischen Zellen und B-Zellen produziert. OPG hemmt die Differenzierung von Osteoklasten und ihre Aktivierung durch die Bindung an RANKL (receptor activator of NFkappaBbeta ligand. OPG könnte daher eine wichtige Rolle in der Verhinderung des Auftretens von Erosionen bei chronischer Polyarthritis spielen. In der vorliegenden Studie wurde untersucht, ob die Serumspiegel von Osteoprotegerin mit Entzündungsparametern oder der Gelenksdestruktion bei chronischer Polyarthritiskorrelieren. Patienten und Methoden: In 85 Sera von 68 Patienten mit chronischer Polyarthritis wurden die Serumspiegel von OPG untersucht und mit klinischen Parametern, Laborbefunden und dem Larsen-Score verglichen. Zur OPG-Bestimmung wurde ein Sandwich-ELISA (enzyme-linked-im-munosorbent-assay mit zwei spezifischen OPG-Antikörpern verwendet. Mit dem bindenden Antikörper wurde eine Mikrotiterplatte beladen, der zweite Biotin-konjugierte Antikörper wurde durch Streptavidin-Peroxidase und TMB gemessen. Der Immunoassay mißt sowohl freies als auch an RANKL gebundenes OPG. Zur statistischen Auswertung wurde ein SAS-Programm verwendet, als Tests wurden der Mann-Whitney-Test, die Spearman-Korrelation und die Varianzanalyse (ANOVA angewandt. Ergebnisse: Verglichen mit einer gesunden Kontrollgruppe (Alter 56-76 Jahre lagen die Mittelwerte von Serum-OPG bei chronischer Polyarthritis höher. Wenn man den Mittelwert der Gesunden für die Einteilung in höhere oder niedrigere Serum-OPG-Werte bei Patienten mit chronischer Polyarthritis verwendet, zeigt sich im Mann-Whitney-Test eine signifikante Korrelation nicht nur mit BSG und Rheumafaktor, sondern auch mit dem Larsen-Score. Die OPG-Spiegel korrelierten mit dem Rheumafaktor, der BSG und dem Serum-CRP (C-reaktives Protein signifikant positiv, der Larsen-Score zeigte nur einen statistischen Trend.

    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 Introduction : Vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches, which affects approximately 0.1–2% of the general population worldwide. Zinc is an essential trace element that is necessary for growth and development at all stages of life. Some studies have reported an association between serum zinc levels and vitiligo. Aim : To measure the serum zinc level in patients with vitiligo compared to healthy subjects. Material and methods : One hundred patients with vitiligo and 100 healthy controls were referred to our clinic. The two groups were matched for age and sex. Atomic absorption spectrophotometry was used to measure serum zinc levels. The statistical analysis was performed using SPSS software. Results : The mean serum level of zinc in vitiligo patients and controls was 80.11 ±17.10 µg/dl and 96.10 ±16.16 µg/dl, respectively. The serum zinc level in patients with vitiligo was significantly lower than in healthy controls (p = 0.0001. Conclusions : The results of our study revealed a significant association between vitiligo and serum zinc levels. A relative decrease in the serum zinc level in vitiligo patients can highlight the role of zinc in the pathogenesis of vitiligo, and large-scale studies need to be conducted to confirm these findings and assess the effect of oral zinc supplements in patients with low zinc levels.

    Full Text Available Background/Aim. Hepcidin, an iron regulatory hormone, is increased in response to inflammation and some infections. We investigated the relationships among serum prohepcidin, iron status, Helicobacter pylori infection status, and the presence of gastric mucosal atrophy. Methods. Seventy subjects undergoing esophagogastroduodenoscopy underwent multiple gastric biopsies, and the possibility of H. pylori infection and the degree of endoscopic and histologic gastritis were investigated. In all subjects, serum prohepcidin and iron parameters were evaluated. Results. No correlations were observed between serum prohepcidin levels and the other markers of anemia, such as hemoglobin, serum iron, ferritin, and total iron binding capacity. Serum prohepcidin levels were not significantly different between the H. pylori-positive group and the H. pylori-negative group. Serum prohepcidin levels in atrophic gastritis patients were significantly lower than those in subjects without atrophic gastritis irrespective of H. pylori infection. Conclusion. Serum prohepcidin levels were not altered by H. pylori infection. Serum prohepcidin levels decrease in patients with atrophic gastritis, irrespective of H. pylori infection. It suggests that hepcidin may decrease due to gastric atrophy, a condition that causes a loss of hepcidin-producing parietal cells. Further investigations with a larger number of patients are necessary to substantiate this point.

However, the relationship between serum calcium and coronary heart disease is unclear. The purpose of this study was to compare serum calcium levels in patients with coronary heart disease and those in healthy individuals. Methods: This retrospective, case-control study conducted in the People's Republic of China comprised 380 cases and 379 controls. Serum calcium levels, blood lipids, and anthropometric measurements were measured in both groups. The Student's unpaired t-test or Chi-square test was used to compare differences between cases and controls. Pearson's partial correlation coefficient was used to determine the association between serum calcium, blood lipids, and blood pressure in both groups. Results: Our results indicate that the average level of serum calcium in cases was higher than in controls. Serum calcium levels showed no correlation with any parameter except for triglycerides in either group. Conclusion: Overall, these data suggest that serum calcium has no influence on coronary heart disease or triglyceride levels in the general population.

    Previous studies assessing the association between serum uric acid levels and neurological outcome after acute ischemic stroke reported conflicting results. A systematic review and meta-analysis were conducted to assess the impact of serum uric acid levels on outcome after acute ischemic stroke. Pubmed, Embase, Web of Science, and Google scholar were searched through September 26, 2014 to identify eligible published or unpublished studies on the association between serum uric acid levels and outcome after acute ischemic stroke. Hazard ratio (HR) for poor outcome or mean differences of serum uric acid levels with 95% confidence intervals (95% CIs) were pooled using meta-analysis. The primary outcome was occurrence of poor outcomes, while the secondary outcome was the mean differences of serum uric acid levels in patients with good or poor outcomes. Ten eligible studies with a total of 8131 acute ischemic stroke patients were included into the meta-analysis. Compared with low serum uric acid level, high serum uric acid level was associated better outcome after acute ischemic stroke (HR = 0.77, 95% CI 0.68-0.88, P = 0.0001). Sensitivity analysis further identified the prognostic role of serum uric acid levels on outcome after acute ischemic stroke. Patients with good outcomes had a higher serum uric acid level compared with those with poor outcome (mean difference = 30.61 μmol/L, 95% CI 20.13-41.08, P acute ischemic stroke. High uric acid level at the onset is a biomarker of better prognosis in patients with acute ischemic stroke.

    To determine whether leptin in patients with CAP acts as a nutritional or as an inflammatory marker and whether leptin plays any role regarding survival, we included 222 patients diagnosed of CAP, 142 men and 80 women, median age 74 years. We did not find significant differences in serum leptin levels between CAP patients and healthy controls, even after adjusting by BMI. Serum leptin levels were directly related with BMI, body fat and muscle mass and inversely related with inflammatory markers, including pro- and anti-inflammatory cytokines. Patients with positive blood cultures showed lower serum leptin and raised inflammatory markers. Although patients who died showed lower values of serum leptin, multivariate analysis showed that the prognostic value of low serum leptin levels depends on impaired nutritional status. In conclusion, we suggest that in CAP patients, leptin does not act as an inflammatory reactant but as a nutritional marker.

    Objective: To study the effect of acupuncture on serum glucagon (GL) and immuno-cytokines in diabetes type-Ⅱ patients. Methods: A total of 120 diabetes type-Ⅱ patients including 70 inpatients and 50 outpatients were randomly divided into simple acupuncture group (n=18), acupuncture plus medication group (n=52) and simple medication group (n=50). Acupoints used were Pishu (BL 20), Yishu, Shenshu (BL 23), Qihai (CV 6), Quchi (LI 11 ), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6), etc. and medicines used were Glipizide (2.5~5 mg, t.i.d.), Dimethyldiguanide hydrochloride (0.25~0.5g, t.i.d.), etc. Serum GL, tumor necrosis factor (TNF)-α and interlukin(IL)-6 contents were determined with radioimmunoassay, and blood sugar was also detected with routine method. Results: After treatment, serum GL, TNF-α and IL-6 contents declined significantly in comparison with pre-treatment (P<0.05, 0.01), and the effect of acupuncture plus medication group is superior to those of simple acpuncture or medication groups, particularly in lowering serum GL (P<0.01 ). Conclusion: The regulative action of acupuncture on blood GL and immuno-cytokine levels maybe contribute to its functions in stabilizing blood sugar and preventing complications.

Keeping this in consideration, the study was conducted on 140 subjects either sex out of which 35 normal adults and 105 gastrointestinal (GI cancer patients. The follow up study was further undertaken and values of serum Cu and Zn of the same patients before and after surgery were recorded. The study showed that there was significant elevation (p<0.01 of serum copper levels before surgery and serum copper levels were deceased significantly (p<0.05 after surgery. Serum Zn level was found significantly (p<0.05 lower in GI cancer patients while the Zn level was increased significantly (p<0.01 after surgery. There was significant increase (p<0.01 in Cu/ Zn ratio of GI cancer patients before surgery in contrast to the control. The serum copper level in patients of GI cancer decreased significantly after surgery resulting normalization of metabolic process. A significant increase in serum Zn levels have been observed after treatment of the patients. The Cu/ Zn ratio decreased significantly after the surgery. These observations clearly indicate that serum Cu, Zn and Cu/ Zn ratio are useful in estimating the extent and prognosis of malignant tumors in digestive organs

    Expected blood levels of common local anesthetics have been reported for numerous types of injections. Comparative levels of mepivacaine and lidocaine after dental injection have been only partially evaluated. A study was designed to compare the circulating serum level of 36 mgs. of mepivacaine with 1:20,000 levonordefrin (M) and 36 mgs. of lidocaine with 1:100,000 epinephrine (L) in 1.8 cc dental cartridges after standardized's bilateral maxillary infiltrations. Each of five subjects received 1.8 cc of (L) to the left maxillary second bicuspid and 1.8 cc of (M) to the right maxillary second bicuspid at a rate of one cc per minute. The serum was sampled before the injections and at 5, 15, 30, 60, 90, 120 and 240 minute intervals after the injections and analyzed by gas liquid chromatography. The results indicated that the serum level of (M) peaked at 30 minutes, 0.37 μg/ml of serum and (L) had peaks at 15 and 30 minutes, 0.22 μg/ml of serum. This difference was statistically significant, (p <.01) at all times sampled with (M) always resulting in a higher serum level. Serum levels persisted throughout the four hour test period.

    Over the past decade, there has been heightened interest in determining if there is an increased risk of adverse reproductive outcomes among women who had a loop electrosurgical excision procedure (LEEP) to remove cervical intraepithelial neoplasia (CIN). The objective of this exploratory study was to determine if the treatment of CIN with a LEEP is associated with changes in cervical soluble immune markers. Cervical cytokine concentrations were measured in women treated with LEEP and a control group of women who had colposcopy only and did not undergo LEEP. Cytokines were examined in cervical secretions collected in Merocel(®) sponges at study entry and at 6-month follow-up. Cytokines were measured using a Luminex 18-plex cytokine bead assay. The mean cytokine levels were not significantly changed from baseline to follow-up in either group, with the exception of TNF-α, which decreased among women who underwent a LEEP. When the mean levels of cytokines of the treated and untreated groups at baseline or follow-up were compared, cytokine levels tended to be lower in the treated group (particularly IFN-γ, IL-6, IL-8, and MCP-1). Findings from adjusted repeated measures analyses revealed no differences between the two groups with regard to changes in cytokine levels over time. Overall, women undergoing a LEEP showed few changes in the cervical microenvironment relative to untreated women. Future studies with additional cervical environment markers and larger sample sizes are needed to determine if a LEEP is associated with dysregulation of the cervical microenvironment.

    Background Glioblastoma (GBM) is an aggressive infiltrative brain tumor with a particularly poor prognosis that is characterized by microvascular proliferation, necrotic tissue, and significant infiltration of M2-like monocytes. Compromised barrier function in tumor vasculature might be expected to permit communication between the tumor microenvironment and peripheral blood. Methods To ascertain whether tumor-derived vesicles and/or factors might reach the bloodstream and what effects these molecules have on the peripheral compartment, we analyzed blood samples collected from primary GBM patients. Results Notably, a significant number of patient sera samples contained tumor exosome-reactive immunoglobulin (Ig)G2 and IgG4 antibody isotypes, which are consistent with Th2 immunity. M2-like monocytes expressing CD14+ and CD163+, another indicator of Th2 bias, are elevated in GBM patient blood and associated with high serum concentrations of colony−stimulating factor 2 and 3, as well as interleukin-2, -4, and -13, the latter 2 cytokines being hallmarks of Th2 immunity. GBM patient sera samples induce high levels of CD163 expression when added to normal monocytes, providing mechanistic evidence of a basis for Th2 bias. Fractionation of GBM patient sera into samples enriched for exosomes or soluble factors proved that both fractions are capable of inducing CD163 expression in normal monocytes. Conclusions The results of the current study indicate a Th2 bias in the periphery of GBM patients, likely as a result of products elaborated by the tumor. Consequentially, through immune modulation these brain tumors exert systemic effects beyond the confines of the CNS. PMID:26180083

    Full Text Available Abstract Background The T-helper (Th1/Th2 dichotomy dominated the field of immune regulation until interleukin (IL-17-expressing T cells (Th17 were proposed to be a third lineage of helper T cells, the key players in the pathogenesis of autoimmune disorders. Autoimmunity to brain tissue may play a pathogenic role in autism. IL-17A is a pro-inflammatory cytokine that has been shown to play an important role in various autoimmune neuroinflammatory diseases. The aim of this study was to measure serum levels of IL-17A in relation to the degree of the severity of autism. Methods Serum IL-17A levels were measured by ELISA in 45 children with autism and 40 matched healthy controls. Results Children with autism had significantly higher serum IL-17A levels than healthy controls (P P = 0.01, and raised serum IL-17A levels were significantly more common in children with severe autism (67.9% than in those with mild to moderate autism (17.6%, P = 0.001. Conclusions Serum IL-17A levels were raised in the group with autism, and the levels correlated significantly with the severity of autism. This is the first study to measure levels of IL-17A in relation to the severity of autism, to our knowledge. Further research, with a larger subject population, is warranted to determine whether the increase of serum IL-17A levels plasma has a pathogenic role in autism, and whether anti- IL-17A therapy could be useful

    We studied 11 unselected men who presented to a Reproductive Endocrinology Clinic with histories of infertility and low sperm counts. Reproductive hormones and semen und serum zinc levels were measured. All men had semen analyses performed on at least three separate occasions. A similar set of laboratory evaluations were performed on 11 other men who had normal semen analyses and no history of infertility. No abnormalities of reproductive hormones were found in either group. Mean serum zinc levels were significantly lower in the infertile men. Mean semen zinc levels were not significantly different. There was no correlation between serum and semen zinc levels in either group. A significant correlation was found between sperm count and semen zinc in the volunteers with normal counts, but not in the oligozoospermic men. The results obtained in this study suggest that lowered serum zinc is more common than formerly appreciated in unselected patients with infertility. The high level of zinc found in semen is due primarily to the secretions of the prostate gland and reflects prostatic stores. Serum zinc is thought to be a reasonable indicator of zinc status. The lack of correlation between serum zinc and semen zinc found in our study suggests that mild zinc deficiency may lower serum zinc while the larger prostatic zinc stores remain unaffected.

    . The experimental period lasted for 21 d. The pigs of control groups with or without rotavirus challenge (C+ or C- ) and experimental groups with or without rotavirus challenge ( T+ or T- ) were fed diets with 220 and 2200 IU/kg 25-OH-D3 , respectively. The C+ and T+ groups were challenged orally with 1 mL human rotavirus ( 1 × 106 TCID50/mL) . The results showed that dietary supplementation with 2200 IU/kg 25-OH-D3 had elevated the level of rotavirus antibody in serum and intestinal contents of pigs with rotavirus challenge at d 5 and 21 ( P <0. 05) . had decreased the serum immunoglobulin G ( IgG) , immunoglobulin M ( IgM) and immunoglobulin A (lgA) contents of pigs without rotavirus challenge at d 5 (P <0. 05) . and had reduced the serum IgA content at d 5 and 15 ( P <0. 05) and serum IgM content at d 15 ( P <0. 01) of pigs with rotavirus challenge. Dietary supplementation with 2200 IU/kg 25-OH-D3 had a decreasing trend of interleukin-2 ( IL-2 )and interleukin-6 ( IL-6 ) levels in serum and intestinal contents and interferon-γ ( IFN-γ) level in intestinal contents of pigs with or without rotavirus challenge ( P > 0. 05 ) . had enhanced the interleukin-4 ( IL-4 ) level in serum and intestinal contents of pigs without rotavirus challenge ( P >0. 05 ) . and had increased the serum IL-4 level at d 5 (P<0. 01) and IL-4 level in intestinal contents at d 15 (P <0. 01) of pigs with rotavirus challenge. These results indicate that dietary supplementation with 2200 IU/kg 25-OH-D3 can increase the rotavirus antibody level in serum and intestinal contents with or without rotavirus challenge, reduce the secretion of proinflammatory cytokines and the inflammatory responses concerned with them, promote the production of anti-inflammatory cytokines and the anti-inflammatory responses concerned with them. and enhance the ability of disease resistance of weanling pigs.

    Serum and CSF ferritin were estimated in 35 consecutive patients of acute leukaemia at the time of admission and on induction of remission. Serum ferritin levels were significantly raised in 94 per cent patients of acute leukaemia. The mean (+/- SD) serum ferritin (314.36 +/- 158.4 micrograms/1) was significantly higher when compared with control values (P less than 0.001). Remission induction resulted in significant fall in serum ferritin values to a mean of 149 (+/- 98.7) micrograms/l (P less than 0.05). Serum ferritin is thus of value in assessing the state of remission and is a sensitive indicator of the leukaemic cell mass and the state of activity of the disease. CSF ferritin levels in acute leukaemia were comparable to normal control values. CSF ferritin did not reflect CNS involvement in acute leukaemia and therefore its value as a tumour marker of CNS infiltration is doubtful.

    Aminoglycosides are highly effective against bacteria but have serious side-effects including ototoxicity and nephrotoxicity. One of the theories in aminoglycosides ototoxicity is that Iron-aminoglycoside complex causes ototoxicity by creating free radicals. Based on this theory, the relationship between serum iron level and amikacin ototoxicity was studied to determine whether more iron results in more ototoxcity. This prospective cohort study was conducted from August 2005 to October 2008. Patients with amikacin prescription and different serum-ferritin levels were examined. Burned patients with amikacin prescription were divided into Group1 (89 patients; serum-ferritin >150) and Group2 (92 patients, serum-ferritin ototoxicity. More iron can create more ototoxicity, and iron deficiency may inhibit aminoglycoside ototoxicity. An increase in MCV may be due to higher serum ferritin and an indication of more ototoxicity.

    Full Text Available Introduction: Alopecia areata (AA is disease characterized by focally, nonscarring hair loss on the scalp or other parts of the body. It affects 1-2% population of both genders and occurs at all age groups. The etiology is unknown, although most evidence supports the hypothesis that AA is a T-cell-mediated autoimmune disease of the hair follicle and that cytokines play an important role.Objective: The aim of our study was to evaluate serum concentrations of IL-1α and IL-1β in patients with AA and healthy subjects and also to asses a possible association between these cytokines and duration of the disease.Methods: Forty six patients with AA and 20 healthy controls were enrolled in the study. Serum concentrations of IL-1α and IL-1β were measured using enzyme-linked immunoassay techniques.Results: The serum level of IL-1α in patients with AA was significantly higher than that in the control group (4.34±0.86 pg/mL vs 3.66±0.35 pg/mL, respectively. IL-1β levels were greater in patients with AA than in controls (2.35±0.17 pg/mL vs 2.24±0.30, respectively but the difference was not significant (p>0.05. No correlations were found between duration of disease and the serum levels of IL-1α and IL-1β.Conclusion: Our results have demonstrated the importance of determining IL-1a concentration in serum in patients with AA. This research could contribute to the interpretation of insufficiently well known views of the pathogenesis role and significance of IL-1α in AA.

    Full Text Available Abstract Background Inflammatory mediators in both the peripheral circulation and central nervous system (CNS are dysregulated in major depressive disorder (MDD. Nevertheless, relatively little is known about the role of the T-helper (Th-2 effector cytokines interleukin (IL-5 and IL-13 in MDD. Methods We examined the serum levels of these cytokines and a Th-1 comparison cytokine, interferon (IFN-γ, in 116 individuals (MDD, n = 58; controls, n = 58. Results In our basic multivariate model controlling for the effects of potential confounders on the associations between MDD and the examined cytokines, each 1-unit increase in the serum IL-5 level increased the likelihood of belonging to the MDD group by 76% (OR 1.76, 95% CI 1.03-2.99, p = 0.04; model covariates: age, gender, marital status, daily smoking and alcohol use. The likelihood further increased in models additionally controlling for the effects of the use of antidepressants and NSAIDS, and a diagnosis of asthma. No such associations were detected with regard to IL-13 (OR 1.08, 95% CI 0.96-1.22, p = 0.22 or IFN-γ (OR 1.02, 95% CI 0.99-1.05, p = 0.23. Conclusions Elevated levels of IL-5, which uses the neural plasticity-related RAS GTPase-extracellular signal-regulated kinase (Ras-ERK pathway to mediate its actions in the central nervous system (CNS, could be one of the factors underlying the depression-related changes in CNS plasticity.

    The serum procalcitonin assay has emerged as a promising biomarker to distinguish between bacterial and viral respiratory tract infections but has not been used to differentiate coccidioidomycosis from bacterial infection. A correlation between procalcitonin serum levels and coccidioidomycosis has never been reported. To determine any association between serum procalcitonin levels and primary pulmonary coccidioidomycosis. We identified and enrolled 20 immunocompetent patients with symptomatic primary pulmonary coccidioidomycosis of coccidioidomycosis at a median of 32 days after symptom onset. Larger prospective studies are needed to confirm this finding.

    When fever occurs in a patient treated with a neuroleptic, the diagnosis of a neuroleptic malignant syndrome is difficult to differentiate to that of an infectious event. Among inflammation biomarkers of inflammation, serum procalcitonin levels increase both quickly and specifically during a bacterial infection. We report the first case of a neuroleptic malignant syndrome associated with a significant increase of serum procalcitonin levels, without concomitant septic syndrome. The neuroleptic malignant syndrome might be a non-infectious clinical situation associated with an increased serum procalcitonin concentration.

    The aim is to examine whether the changes in pleural fluid interleukin (IL)-1β, IL-2, IL-6, and IL-8 levels were significant in differential diagnosis of childhood pleural effusions. IL-1β, IL-2, IL-6, and IL-8 levels in pleural fluids of all 36 patients were measured. The levels of IL-1β, IL-2, IL-6, and IL-8 in pleural fluids were statistically significantly higher in the transudate group compared with those of the exudate group. The levels of IL-1β, IL-6, and IL-8 were also found to be statistically significantly higher in the empyema group compared with both the parapneumonic and the tuberculous pleural effusion groups. The levels of IL-2 and IL-6 were detected to be statistically significantly higher in the tuberculous pleural effusion group in comparison with those of the parapneumonic effusion group. The results showed that pleural fluids IL-1β, IL-2, IL-6, and IL-8 could be used in pleural fluids exudate and transudate distinction. PMID:15770060

    Full Text Available Abstract. We investigated effects of combined oral contraceptives (COC containing low- and microdoses of estrogenic components upon serum levels of macroglobulin family proteins (alpha-2-macroglobulin, α2-MG, and pregnancy-associated alpha-2-glycoprotein, α2-PAG, their immune complexes with IgG, as well as concentrations of some cytokines (IL-1β, IL-6, TNFα, IFNγ. It was shown that cytokine levels did not differ with control, whereas α2-MG concentrations showed a time-dependent decrease in a group of women taking COC with microdoses of estrogens, and α2-PAG levels increased tenfold, independent on dosage and time of COC application. Meanwhile, contents of PAG-IgG complexes exhibits a gradual decrease, along with increase in MG-IgG. Considering PAG as a marker of normal and malignant proliferation, we suggest, that the levels of α2-PAG may be useful in monitoring of women taking COC, in order to predict high risk of pathological  proliferation  by  evaluation  of  individuals with  elevated  α2-PAG  levels.  (Med.  Immunol.,  2011, vol. 13, N 6, pp 635-638

    We trained and tested young (6–8 mo; n = 13), middle-aged (12–14 mo; n = 41), and aged (22–24 mo; n = 24) male Fischer 344 rats in a rapid acquisition water maze task and then quantified 27 stress hormones, cytokines and chemokines in their serum, hippocampi and frontal cortices using bead assay kits and xMAP technology. Middle-aged and aged rats learned the location of the hidden platform over training trials more slowly than their young counterparts. After training, young rats outperformed middle-aged and aged rats on both immediate and 24h retention probe trials and about half of the middle-aged and aged (aging) rats exhibited impaired performances when tested on the retention probe trial 24h later. The concentrations of many serum, hippocampal and cortical analytes changed with age often in networks that may represent age-sensitive signaling pathways and the concentrations of some of these analytes correlated with water maze learning and/or memory scores. Serum GRO/KC and RANTES levels, hippocampal GM-CSF levels and cortical IL-9 and RANTES levels were significantly higher in rats categorized as memory-impaired versus elite agers based upon their 24h probe trial performances. Our data add to the emerging picture of how age-related changes in immune and neuroimmune system signaling impacts cognition. PMID:26093306

    BACKGROUND AIMS. Pro-angiogenic cytokines can affect myeloma cell proliferation directly and indirectly through stimulation of cancer-associated angiogenesis. METHODS. We investigated how peripheral blood stem cell (PBSC) collection affected plasma angioregulatory cytokine levels in 15 consecutive myeloma patients. RESULTS. Plasma levels of hepatocyte growth factor (HGF) were significantly increased prior to apheresis in patients compared with donors, and a further increase was detected immediately after PBSC apheresis. HGF levels decreased within 24 h, but were still higher than the levels in healthy donors, whose HGF levels were not altered by platelet apheresis. Pre-apheresis levels of other angioregulatory cytokines, angiopoietin-2 and vascular endothelial growth factor (VEGF), were also increased in patients, whereas angiopoietin-1, angiogenin and basic fibroblast growth factor levels did not differ from healthy controls. PBSC harvesting decreased angiopoietin-1 and VEGF levels, increased the microvascular endothelial cell marker endocan levels but did not affect the other mediators. CONCLUSIONS. Our results show that PBSC apheresis alters systemic angioregulatory profiles in myeloma patients. This cytokine modulation is not a general characteristic of all apheresis procedures and was not seen in healthy platelet donors.

    Breast cancer is both one of the most common and one of the most treatable of all human malignancies. It has been suggested by various investigators that sialic acid increases in the sera of cancerous patients. In cancer patients, an increase in the levels of serum sialic acid may also be due to an increase in the activity of serum or tissue sialidase. The purpose of the present investigation was to determine whether the concentration of sialidase in serum and breast tissue could be used as a tumor marker in breast cancer. In this study; serum sialidase levels in 26 patient with breast cancer and 31 controls were found to be 77.04+/-25.07 U/l and 55.56+/-7.50 U/l, respectively. The mean tissue sialidase levels in 26 breast cancer patients and 13 controls were 39.76+/-17.03 U/g protein and 14.30+/-7.09 U/g protein, respectively. Serum and tissue sialidase levels in breast cancer were significantly higher than those found in the control group (P breast cancer patients were found to be 67.73+/-11.87 U/l and 33.41+/-12.17 U/g protein and 87.89+/-31.94 U/l and 47.17+/-19.30 U/g protein, respectively. Also we found a significant difference between the levels of serum and tissue sialidase in Grade I-II and III (P < 0.05).

    Interleukin 35 (IL-35) is a newly discovered anti-inflammatory cytokine. Recent studies have indicated that it plays a crucial role in the pathogenesis of autoimmune diseases. In humans, IL-35 is predominantly secreted from regulatory T cells. This study aimed to measure serum IL-35 levels in patients with rheumatoid arthritis (RA) and in control individuals, and analyze its association with disease indicators of RA. One hundred patients with RA were recruited, and 50 volunteers were enrolled as healthy controls. Serum IL-35 levels were measured using an enzyme-linked immunosorbent assay kit. RA patients showed significantly lower serum levels of IL-35 compared with healthy controls (p elevated percentage (> 75%) of neutrophils (p anti-cyclic citrullinated peptide (CCP) antibodies (n = 78) and those without anti-CCP antibodies (n = 22). However, among patients without anti-CCP antibodies, the serum IL-35 levels were lower in patients with erosive arthritis (n = 8) than those patients without erosion (n = 14) (p anti-CCP antibodies. In conclusion, IL-35 plays a protective role in the pathogenesis of RA.

    Psoriasis is a chronic autoimmune disease involving a complex network of cytokines such as interleukin (IL)-6. We tested the hypothesis that serum IL-6 level is a useful indicator of disease activity and predicts the treatment response to biologics in patients with psoriasis. We analyzed 113 psoriasis patients treated with biologics (73 with infliximab [IFX], 24 with adalimumab [ADA], and 16 with ustekinumab [UST]) in our hospital. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI) score, and Disease Activity Score 28 based on C-reactive protein (DAS28-CRP). Before treatment, serum IL-6 levels significantly correlated with PASI scores in patients with psoriasis vulgaris (r = 0.432, p = 0.001) and with DAS28-CRP in patients with psoriatic arthritis (r = 0.469, p = 0.010). Serum IL-6 levels were significantly decreased by IFX (from 4.8 to 1.5) and ADA (from 2.5 to 1.4) therapy. In psoriatic arthritis, serum IL-6 levels at the endpoint tended to be lower in patients who achieved DAS28-CRP psoriasis and for predicting responsiveness of joint symptoms to biologic treatment.

    PIVKA-II has been practically used as a tumor marker of hepatocellular carcinoma. On the other hand, increased serum PIVKA-II concentration was reported in a Japanese patient who had hyperthyroidism without liver diseases. To evaluate whether thyroid hormone is related with serum PIVKA-II, we examined serum PIVKA-II concentrations in patients with various thyroid diseases. Eight patients with Hashimoto disease, 24 patients with Graves' disease, and 8 healthy subjects were studied. There was no significant difference of serum PIVKA-II levels among the three groups. However, serum PIVKA-II concentrations(mean +/- SD mAU/ml) in hyperthyroidism(37 +/- 27) were significantly higher than those in hypothyroidism(16 +/- 9) and normal controls(12 +/- 4) (p PIVKA-II concentrations decreased in accordance with the decrease of serum FT4 concentrations. Our data indicate that serum PIVKA-II concentration was increased in patients with hyperthyroidism, but further in vivo studies are necessary to clarify the mechanism related to increased serum PIVKA-II by thyroid hormone.

    Full Text Available Anterior cruciate ligament (ACL reconstruction restores knee stability but does not reduce the incidence of posttraumatic osteoarthritis induced by inflammatory cytokines. The aim of this research was to longitudinally measure IL-1β, IL-6, IL-8, IL-10, and TNF-α levels in patients subjected to ACL reconstruction using bone-patellar tendon-bone graft. Synovial fluid was collected within 24–72 hours of ACL rupture (acute, 1 month after injury immediately prior to surgery (presurgery, and 1 month thereafter (postsurgery. For comparison, a “control” group consisted of individuals presenting chronic ACL tears. Our results indicate that levels of IL-6, IL-8, and IL-10 vary significantly over time in reconstruction patients. In the acute phase, the levels of these cytokines in reconstruction patients were significantly greater than those in controls. In the presurgery phase, cytokine levels in reconstruction patients were reduced and comparable with those in controls. Finally, cytokine levels increased again with respect to control group in the postsurgery phase. The levels of IL-1β and TNF-α showed no temporal variation. Our data show that the history of an ACL injury, including trauma and reconstruction, has a significant impact on levels of IL-6, IL-8, and IL-10 in synovial fluid but does not affect levels of TNF-α and IL-1β.

    In order to evaluate the role of cytokines in the development of polymodal local and distant effects in patients with stages I-IV cervical cancer, the following parameters were measured: serum concentrations of TNF-α, IFN-γ, IL-1β, IL-6, and IL-10; levels of malondialdehyde, activities of catalase, superoxide dismutase, glutathione reductase, and glutathione-S-reductase in the plasma, erythrocyte, and cervix uteri homogenate. The expression of p53, Bcl-2, VEGF, and Ki-67 in tumor tissue was evaluated. High levels of malondialdehyde in tumor tissue and erythrocyte were paralleled by low levels of superoxide dismutase and catalase and high activities of glutathiones. Medium correlations between Ki-67, Bcl-2, and p53 and the levels of IL-6, IL-10, and TNF-α at stages Ib-IIa were detected. The results indicated that the progress of cervical cancer was associated with the neoplasm integration in the host homeostasis by using the regional and systemic cytokine functions. These effects, amplifying the biological potential of the tumor, were the most significant at stages Ib-IIa.

    Full Text Available Aim: Several epidemiological studies have shown an inverse correlation between allergy and brain cancer. The purpose of this study was to compare the serum IgE levels between patients with gliomas and nonglial tumors and their possible prognostic role. Methods: A total of 84 patients with intracranial tumors were included in this study. At clinical presentation, estimation of serum IgE levels was assessed by nephelometry. Detailed information regarding the history of allergies was collected by interview. Results: Of the 84 cases, 42 were gliomas, 23 were meningiomas, 16 were metastases and 3 were primary central nervous system lymphomas. Patients with high-grade glioma had lower IgE levels than patients with low-grade glioma. Patients with glioma and meningioma had statistical significant lower serum IgE levels than patients with metastases. Patients with glioblastoma with serum IgE levels greater than 24 U/mL had a better survival. Conclusion: Patients with glioma and meningioma had lower IgE levels than patients with metastatic lesions. A prognostic role of serum IgE levels was found in glioblastoma. Further studies in larger patient series are required in order to verify our preliminary observations.

    Full Text Available Regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. The historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subjects as control group. Both groups had the same age and weight ranges, sex, and diet, without any periodontal treatment history in the past six months, underling systemic disease such as diabetes, anti-hyperlipidemic drugs or active tobacco smoking history. Low Density Lipoprotein (LDL, High Density Lipoprotein (HDL, Triglyceride (TG and Total Cholesterol (CHOL were measured by direct enzymatic assay. TG level was 128.4±71.1 mg/dl in control group and 165.2± 83.7 in case group indicating a significantly higher level in case group (P<0.05. In control group, 30.8 percent and in case group, 61.5 percent had abnormal serum cholesterol levels, which presents a significantly higher level in case group (P<0.03. Other serum level indices did not show any significant difference. Although it seems that patients with chronic periodontal disease are more susceptible to hyperlipidemia, it is doubtful that the former causes an increase in serum lipid levels, so we suggest studying the effects of treating chronic periodontitis on serum lipid level.

    This study tested the hypothesis that the diurnal variations of serum-erythropoietin concentration (serum-EPO) observed in normoxia also exist in hypoxia. The study also attempted to investigate the regulation of EPO production during sustained hypoxia. Nine subjects were investigated at sea level...... and during 4 days at an altitude of 4350 m. Median sea level serum-EPO concentration was 6 (range 6-13) U.l-1. Serum-EPO concentration increased after 18 and 42 h at altitude, [58 (range 39-240) and 54 (range 36-340) U.l-1, respectively], and then decreased after 64 and 88 h at altitude [34 (range 18...... in 2, 3 diphosphoglycerate. After 64 h at altitude, six of the nine subjects had down-regulated their serum-EPO concentrations so that median values were three times above those at sea level. These six subjects had significant diurnal variations of serum-EPO concentration at sea level; the nadir...

    Full Text Available Although myocardial angiogenesis is thought to play an important role in heart failure (HF, the involvement of circulating proinflammatory and proangiogenic cytokines in the pathogenesis and/or prognosis of HF has not been deeply investigated. By using a highly standardized proliferation assay with human endothelial cells, we first demonstrated that sera from older (mean age 52±7.6 years; n=46 healthy donors promoted endothelial cell proliferation to a significantly higher extent compared to sera obtained from younger healthy donors (mean age 29±8.6 years; n=20. The promotion of endothelial cell proliferation was accompanied by high serum levels of several proangiogenic cytokines. When we assessed endothelial cell proliferation in response to HF patients’ sera, we observed that a subset of sera (n=11 promoted cell proliferation to a significantly lesser extent compared to the majority of sera (n=18. Also, in this case, the difference between the patient groups in the ability to induce endothelial cell proliferation correlated to significant (P<0.05 differences in serum proangiogenic cytokine levels. Unexpectedly, HF patients associated to the highest endothelial proliferation index showed the worst prognosis as evaluated in terms of subsequent cardiovascular events in the follow-up, suggesting that high levels of circulating proangiogenic cytokines might be related to a worse prognosis.

  1. Sleep loss and cytokines levels in an experimental model of psoriasis.

    Directory of Open Access Journals (Sweden)

    Camila Hirotsu

    Full Text Available Up to 80% of people develop a cutaneous condition closely connected to their exposure to stressful life events. Psoriasis is a chronic recurrent inflammatory skin disorder with multifactorial etiology, including genetic background, environmental factors, and immune system disturbances with a strong cytokine component. Moreover, psoriasis is variably associated with sleep disturbance and sleep deprivation. This study evaluated the influence of sleep loss in the context of an animal model of psoriasis by measuring cytokine and stress-related hormone levels. Male adult Balb/C mice with or without psoriasis were subjected to 48 h of selective paradoxical sleep deprivation (PSD. Sleep deprivation potentiated the activities of kallikrein-5 and kallikrein-7 in the skin of psoriatic groups. Also, mice with psoriasis had significant increases in specific pro-inflammatory cytokines (IL-1β, IL-6 and IL-12 and decreases in the anti-inflammatory cytokine (IL-10 after PSD, which were normalized after 48 h of sleep rebound. Linear regression showed that IL-2, IL-6 and IL-12 levels predicted 66% of corticosterone levels, which were selectively increased in psoriasis mice subject to PSD. Kallikrein-5 was also correlated with pro-inflammatory cytokines, explaining 58% of IL-6 and IL-12 variability. These data suggest that sleep deprivation plays an important role in the exacerbation of psoriasis through modulation of the immune system in the epidermal barrier. Thus, sleep loss should be considered a risk factor for the development of psoriasis.

    AIM: TO investigate the cellular defects by analyzing the (Th1/Th2) cytokine levels in vaccine responders and non-responders.METHODS: Peripheral blood mononuclear cell (PBMC) from responders and non-responders were stimulated with or with out recombinant HBsAg or PHA. Broad spectrum of cytokines viz (Th1) IFN-γ, IL-2, TNF-α, IL-12 and (Th2) IL-10, IL-4 were measured after in vitro stimulation with recombinant HBsAg and were compared with respective antibody titers.RESULTS: A significant decrease (P = 0.001) in Th1 and Th2 cytokines namely, IL-2, INF-γ, TNF-α and IL-10 in non-responders was observed. The level of IL-4 was not significant between the three groups. Furthermore, despite a strong Th1 and Th2 cytokine response, the level of IL-12 was elevated in high-responders compared to other groups (P=0.001) and demonstrated a positive correlation with anti-HBs titers and Th1 cytokine response.CONCLUSION: Our findings suggest that unresponsiveness to recombinant hepatitis B vaccines (rHB) is multifactorial, including specific failure of antigen presentation or the lack of both T helper Th1 and Th2 response.

    Background Bilirubin is the end product of heme catabolism and has strong antioxidant properties.Serum bilirubin levels are reported to be reduced in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO).The pathophysiology of optic neuritis (ON) resembles that of MS; however,the role of endogenous bilirubin in ON is unclear.The aim of this study is to measure serum bilirubin levels in patients with ON,and to investigate the correlation between ON and serum antioxidant status of bilirubin.Methods Serum levels of bilirubin were measured in 42 patients with ON,50 patients with multiple sclerosis (MS),48 patients with neuromyelitis optica (NMO) and 48 healthy control subjects.Results Serum total bilirubin (Tbil),direct bilirubin (Dbil) and indirect bilirubin (Ibil) levels in patients with ON were significantly lower than those in the healthy controls.However,no statistical significance was found between levels in the ON and MS,ON and NMO,and MS and NMO groups.In patients with ON,serum Tbil,Dbil,and Ibil levels were lower in those with recurrence or those with ON for a longer duration (>1 year).Moreover,Tbil,Dbil,and Ibil concentrations were lower in patients with papillitis than in those with retrobulbar type ON,but the differences were not statistically significant.Conclusions Low antioxidant status may exist in patients with ON.But serum levels of Tbil,Dbil,and Ibil did not correlate with clinical presentations,such as recurrence,duration of disease and subtypes of ON.Low antioxidant status already existed in MS or NMO patients before systemic symptoms appeared.

    In this case report, we examined the levels of cytokines expressed before and during fecal stream diversion and after intestinal continuity was restored in a patient with collagenous colitis. We report the case of a 46-year-old woman with chronic, active collagenous colitis who either failed to achieve clinical remission or experienced adverse effects with the following drugs: loperamide, cholestyramine, budesonide, methotrexate and adalimumab. Due to the intractable nature of the disease and because the patient was having up to 15 watery bowel movements per day, she underwent a temporary ileostomy. Colonic biopsies were analyzed for mucosal cytokine protein levels before and during fecal stream diversion and after intestinal continuity was restored. Mucosal protein levels of interleukin (IL)-1β, IL-2, IL-6, IL-12, IL-17 A, IL-23, TNF, IFN-γ, IL-4, IL-5, IL-10 and IL-13 were all higher during active disease and decreased to non-detectable or considerably lower levels during fecal stream diversion. One month after the restoration of bowel continuity, when the patient experienced a relapse of symptoms, IL-2, IL-23 and IL-21 levels were again increased. Our results indicate that fecal stream diversion in this patient suppressed the levels of all cytokines analyzed in colonic biopsies. With the recurrence of clinical symptoms and histological changes after bowel reconstruction, the levels of primarily proinflammatory cytokines increased. Our findings support the hypothesis that a luminal factor triggers the inflammation observed in collagenous colitis. PMID:26019474

    We aimed to assess the relationship between cytokine levels and the severity of the manic period in medication free patients. 30 Medication free patients and 28 healthy subjects (HS) were recruited. Plasma levels of pro-inflammatory, anti-inflammatory, inflammatory cytokines, and hs-CRP levels were investigated upon hospital admission, after six weeks follow up in bipolar disease manic episode and the results were compared to HS. The severity of the manic episodes was assessed according to the Young mania rating scale. TNF-α, INF-γ, IL-6 and hs-CRP levels were significantly higher in patients with manic episode of bipolar I disorder before treatment than HS. After treatment the levels of TNF-α, INF-γ, IL-6 and hs-CRP were observed to be significantly decreased. There was no difference between the levels of anti-inflammatory cytokines in patients before or after treatment of bipolar disorder and HS. hs-CRP was observed to be the only parameter correlated with clinical response. The most significant outcome of this study is the correlation between clinical outcome and hs-CRP levels in treatment naive manic episode bipolar type I patients. hs-CRP is the most consistent indicator according to pro-inflammatory, inflammatory and anti-inflammatory cytokines, in predicting treatment outcomes.

    Type 1 narcolepsy is caused by a loss of hypocretin (orexin) signaling in the brain. Genetic data suggests the disorder is caused by an autoimmune attack on hypocretin producing neurons in hypothalamus. This hypothesis has however not yet been confirmed by consistent findings of autoreactive....... In this study, we tested whether an active immune process in the brain could be detected in these patients, as reflected by increased cytokine levels in the cerebrospinal fluid (CSF). Using multiplex analysis, we measured the levels of 51 cytokines and chemokines in the CSF of 40 type 1 narcolepsy patients...

    Background Ferritin is associated with various cardiometabolic risk factors such as dyslipidemia, hypertension, obesity, and insulin resistance in adults. We aimed to study the association between serum ferritin levels and dyslipidemia in adolescents, because dyslipidemia is considered an important modifiable cardiovascular risk factor in the young. Methods We analyzed 1,879 subjects (1,026 boys and 853 girls) from the 2009–2010 Korean National Health and Nutrition Examination Survey IV. Subjects were categorized into quartiles according to their lipid parameters, which were classified according to age and gender. Those in the highest quartile groups for total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglyceride concentrations were diagnosed as having dyslipidemia. Those in the lowest quartile for high-density lipoprotein cholesterol (HDL-C) values were diagnosed with abnormal levels. Results In boys, total cholesterol, LDL-C, and triglyceride concentrations were significantly correlated with serum ferritin levels. In both boys and girls, serum ferritin levels were negatively associated with HDL-C values, even after adjusting for all covariates. Furthermore, there was no significant correlation between serum ferritin levels and total cholesterol, LDL, and triglyceride concentrations in girls. Conclusion Serum ferritin levels were significantly associated with major dyslipidemia parameters, more prominently in boys than in girls, and this association represents a cardiometabolic risk factor.

    The aim of present study was to investigate serum homocysteine levels in apparently healthy vegetarians and ominvores in Mithi, district Tharparker, Sindh, Pakistan. This study was conducted in the Department of Biochemistry, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Center (JPMC), Karachi and blood samples were collected from Mithi, district Tharparker, Sindh, Pakistan, in 2012. One hundred vegetarian and one hundred omnivores (age ranging from 20-40 years) were enrolled for this study. Serum homocysteine levels were measured by the chemiluminescence enzyme immunoassay method. Serum homocysteine (Hcy) level was considerably higher (pvegetarian group compared to omnivores. We further grouped and analyzed our study subjects according to their gender and according to Hcy level (greater than or lower than 15µmol/L). A considerable number of vegetarian subjects 30% were having Hcy >15µmol/L compared to omnivores 6%, (p15µmol/L serum Hcy level in vegetarian group and 6.9% male and 3.5% females had >15µmol/L serum Hcy level in omnivores group, but the difference was not significant in any group. Vegetarians are more prone to develop hyperhomocysteinemia, so they are at high risk to develop cardiovascular disease.

    Full Text Available Background and Design: In recent years, the role of oxidative stress in vitiligo has been widely investigated. Iron and ferritin have important roles in inflammation and oxidative reactions. However, up to date, there are very limited studies on iron metabolism in patients with vitiligo. In this study, we aimed to investigate serum iron and ferritin levels in patients with localized and generalized vitiligo in comparison with a control group.Material and Method: The study groups comprised 68 patients with vitiligo who did not receive systemic treatment or phototherapy in the preceding month, and 72 age- and sex-matched patients with skin disorders other than vitiligo including tinea pedis, melanocytic nevi, and keratoses. Blood samples for serum iron and ferritin levels were obtained before breakfast, after verbal informed consent.Results: No statistically significant differences were found between vitilligo patients and control population with regard to serum levels of iron and ferritin (p=0.478, p=0.307. Patients with localized and generalized vitiligo were also similar for these parameters (p=0.054, p=0.867. Moreover, serum levels of iron and ferritin did not show any significant correlation with disease duration (p=0.382, p=0.485. Conclusion: Our results showed that serum iron and ferritin levels were similar in patients with vitiligo and control subjects. Further studies determining the skin levels of iron and ferritin may elucidate the probable role of these molecules in vitiligo.

    after delivery and try to correlate these proteins with tumor necrosis factor-α, interleukin -1β, and interleukin-8. Acute-phase proteins and cytokines were measured by ELISA in 24 healthy pregnant women undergoing vaginal delivery or Cesarean section. Cord blood samples in addition to maternal blood were collected. SAA and CRP reached the maximum maternal serum levels 24 hours after delivery, while cytokines remained constant over time. SAA and CRP were significantly higher in maternal serum than in newborn's (P<.001 at the moment of delivery. SAA and CRP, regardless of the type of delivery, reproduce the common pattern observed in most inflammatory conditions. Proinflammatory cytokine serum levels do not mirror the increase in SAA and CRP levels.

    Background: T helper (Th) cell cytokines modulate inflammation and play a role in biliary atresia (BA). The aim of the study is a cross-sectional assessment of the levels of Th cytokines in the jaundice-free post Kasai procedure patients. Methods: There were 40 jaundice-free patients with BA and 28 normal controls enrolled. Patients were divided into 3 groups, including normal liver function, impaired liver function, and portal hypertension. Plasma concentration of Th1 [interferon-γ (INF-γ), interleukin (IL)-2], Th2 (IL-4, IL-10), Th3 [transforming growth factor-β1 (TGF-β1)], Th17 (IL-17) cytokines, and stromal cell-derived factor-1α (SDF-1α) were investigated. Results: The IFN-γ level was significantly higher in the BA patients with impaired liver function and portal hypertension than controls (P<0.0001 andP<0.0001, respectively). There was a signifi cantly increase of TGF-β1 in all BA groups compared with controls (P=0.003). The reduction of SDF-1α expression was found in BA groups (P<0.0001). IL-10 levels significantly correlated with aspartate aminotransferase to platelet ratio index (r=0.496, P=0.001). For the cytokine correlations, there were no correlations of Th1, Th2 and Th17 cytokine with the other measured cytokines, but TGF-β1 was negatively correlated with SDF-1α levels (r=-0.327,P=0.039). Conclusions: IFN-γ and IL-10 are likely to be involved in the disease progression in BA. Besides, TGF-β1 is found to be a suppression marker associated with SDF-1α levels and reduced production of TGF-β1 may be associated with the disease progression.

    Chronic inflammation associated with inflammatory bowel disease (IBD) results in increased oxidative stress that damages the colonic microenvironment. Low levels of serum bilirubin, an endogenous antioxidant, have been associated with increased risk for Crohn’s disease (CD). Therefore, the aim of this study was to examine whether total serum bilirubin levels are associated with ulcerative colitis (UC). We identified a retrospective case-control population (n = 6,649) from a single tertiary care center, Penn State Hershey Medical Center (PSU) and a validation cohort (n = 1,996) from Virginia Commonwealth University Medical Center (VCU). Cases were age- and sex-matched to controls (PSU: CD n = 254, UC n = 187; VCU: CD n = 233, UC n = 124). Total serum bilirubin levels were obtained from de-identified medical records and segregated into quartiles. Logistic regression analysis was performed on each quartile of total serum bilirubin compared to the last quartile (highest bilirubin levels) to determine the association of total serum bilirubin with UC. Similar to CD patients, UC patients demonstrated reduced levels of total serum bilirubin compared to controls at PSU and VCU. The lowest quartile of total serum bilirubin was independently associated with UC for the PSU (OR: 1.98 [95% CI: 1.09–3.63]) and VCU cohorts (OR: 6.07 [95% CI: 3.01–12.75]). Lower levels of the antioxidant bilirubin may reduce the capability of UC patients to remove reactive oxygen species leading to an increase in intestinal injury. Therapeutics that reduce oxidative stress may be beneficial for these patients. PMID:28594959

    Full Text Available Objective: To measure serum leptin and insulin levels in women with recurrent pregnancy loss using modified methods of High Performance Liquid Chromatography (HPLC, and to examine their influence on recurrent loss at different pregnancy trimesters.Methods: A case control study was conducted from, 1 September 2008 to 30 December 2009 in the Obstetric and Gynecological Department-Al-Khadimiya Teaching Hospital. HPLC technique with new modified method was used to estimate serum leptin and insulin hormones in samples of women with recurrent pregnancy loss (patients group, n=64 and healthy pregnant women at the end of the third gestational trimester as a control group (n=51.Results: Both serum leptin and insulin levels were high in women with pregnancy loss in their three trimesters. A significant correlation was found between age (r=0.535, p<0.018 and serum total leptin in women with RPL during the first trimester. Also, a highly significant correlation was found between serum total leptin and insulin in women with RPL during the first, second and third trimesters (r=0.894, r=0.931, and r =0.995 respectively. The number of women who lost their pregnancy during the first trimester was higher than those losing during other trimesters.Conclusion: It can be concluded that recurrent pregnancy loss in women at different trimester is associated with endocrine abnormalities where serum leptin and insulin levels increase in a different way compared with normal healthy pregnant women.

    Low-grade inflammation, measured by circulating levels of cytokines, is a pathogenic mechanism for several chronic diseases of aging. Identifying factors related to inflammation among African-American youths may yield insights into mechanisms underlying racial disparities in health. The purpose of the study was to determine whether (1) reported racial discrimination from ages 17-19 years forecasts heightened cytokine levels at the age of 22 years and (2) this association is lower for youths with positive racial identities. A longitudinal research design was used with a community sample of 160 African-Americans who were aged 17 years at the beginning of the study. Discrimination and racial identity were measured with questionnaires, and blood was drawn to measure basal cytokine levels. Ordinary least squares regression analyses were used to examine the hypotheses. After controlling for socioeconomic risk, life stress, depressive symptoms, and body mass index, racial discrimination (β = .307; p racial identity (β = -.179; p racial discrimination evinced elevated cytokine levels 3 years later. This association was not significant for young adults with positive racial identities. High levels of interpersonal racial discrimination and the development of a positive racial identity operate jointly to determine low-grade inflammation levels that have been found to forecast chronic diseases of aging, such as coronary disease and stroke.

    Psoriasis vulgaris is a chronic inflammatory disease of the skin with a strong genetic component and immune system involvement. Although some evidence suggests that Natural Killer (NK) cells may play a part in psoriasis, their role is relatively unstudied and results are controversial. In this current study, NK cells from psoriasis patients exhibited reduced degranulation and produced lower levels of the pro-inflammatory cytokines IFN-γ and TNF-α. Further investigation found that NK cells from psoriasis patients and healthy controls expressed similar levels of activation markers, NK cell receptors and apoptosis-inducing molecules. In addition, comparable levels of several cytokines important in NK cell biology were found in the serum of psoriasis patients and healthy controls. Genotyping analysis revealed that HLA-C2, which provides a ligand for killer-cell immunoglobulin-like receptors (KIR) expressed by NK cells, was strongly associated with psoriasis susceptibility. However, no link between the KIR genes themselves and disease was found. Copyright © 2015 Elsevier Inc. All rights reserved.

    Chronic alcohol use alters adaptive immunity and cytokine activity influencing immunological and hormone responses, inflammation, and wound healing. Brain cytokine disturbances may impact neurological function, mood, cognition and traits related to alcoholism including impulsiveness. We examined the relationship between plasma cytokine levels and self-rated psychiatric symptoms in 40 adult males (mean age 51 ± 6 years; range 33-58 years) with current alcohol dependence and 30 control males (mean age 48 ± 6 years; range 40-58 years) with no history of alcoholism using multiplex sandwich immunoassays with the Luminex magnetic-bead based platform. Log-transformed cytokine levels were analyzed for their relationship with the Symptom Checklist-90R (SCL-90R), Barratt Impulsivity Scales (BIS) and Alcoholism Severity Scale (ASS). Inflammatory cytokines (interferon γ-induced protein-10 (IP-10); monocyte chemoattractant protein-1 (MCP1); regulated on activation, normal T cell expressed and secreted (RANTES)) were significantly elevated in alcoholism compared to controls while bone marrow-derived hematopoietic cytokines and chemokines (granulocyte-colony stimulating factor (GCSF); soluble CD40 ligand (sCD40L); growth-related oncogene (GRO)) were significantly reduced. GRO and RANTES levels were positively correlated with BIS scales; and macrophage-derived chemokine (MDC) levels were positively correlated with SCL-90R scale scores (p alcoholism may influence brain function leading to increased impulsiveness and/or phobia. The novel association between RANTES and GRO and impulsivity phenotype in alcoholism should be further investigated in alcoholism and psychiatric conditions with core impulsivity and anxiety phenotypes lending support for therapeutic intervention.

    It is widely accepted that neuroinflammatory processes play an important role in the pathogenesis of Alzheimer's disease (AD) and high levels of cytokines and chemokines are detected around Aβ plaques. As neuroinflammation is involved in the development and progression of AD, we measured the pro-inflammatory cytokines interleukin 1β (IL-1β), IL-8 and tumor necrosis factor α (TNF-α) in serum and cerebrospinal fluid (CSF) samples from 45 AD patients and 53 age-matched control subjects using a highly sensitive multiplex electrochemiluminescence assay. To address the association with disease progression we correlated cognitive status with cytokine levels. CSF as well as serum IL-8 levels were found to be significantly lower in AD patients than in controls (p = 0.02). A statistically significant inverse correlation was observed between the CSF level of IL-1β and the MMSE score (rs = -0.03, p = 0.02). We therefore stratified the AD patients by their MMSE scores into three equal groups and found that in the AD group with the most severe cognitive impairment CSF-IL-1β was significantly increased compared to age-matched controls (p < 0.05), whereas in the other investigated groups the increase was not statistically significant. Our results confirm data suggesting that cytokine alterations are involved in AD pathogenesis and may be helpful as a biomarker for monitoring disease progression.

    Studies were undertaken to determine whether differences in serum cytokine balances could be involved in the pathogenesis of allergic and in non-allergic asthma. At this propose, interferon-gamma, tumor necrosis factor-alpha, interleukin-2, interleukin-4, interleukin-6, and interleukin-10 were measured by enzimoimmunoassay. The analysis was performed on 24 allergic and 24 non-allergic asthmatic patients and 16 healthy subjects. IFN-gamma and TNF-alpha, included into the type 1 cytokines, appeared significantly increased in the allergic with respect to the non-allergic asthmatic patients (p = 0.01) and (p < 0.001) respectively, while IL-10, which belongs to the type 2 cytokines, was significantly increased in the non-allergic asthmatic (p < 0.001). The IL-6 analysis did not show any significant difference in either of the study group. The most interesting finding was the high serum IL-10 values detected in intrinsic asthmatic patients, which in turn, suggests that this cytokine could participate in the regulation of different immunological features that occurs in non-allergic asthma, and maybe it could indicate a higher stimulated state of cells in this type of asthma. The data presented in this report show a different cytokine profile in serum from allergic and non-allergic asthmatic patients and denote a stronger prevalence of type 2 cytokines in intrinsic asthma.

    Asami Ota

    Full Text Available Low serum albumin levels are associated with aging and medical conditions such as cancer, liver dysfunction, inflammation, and malnutrition and might be an independent predictor of long-term mortality in healthy older populations. We tested the hypothesis that economic status is associated with serum albumin levels and explained by nutritional and health status in Japanese older adults.We performed a cross-sectional analysis using data from the Japan Gerontological Evaluation study (JAGES. The study participants were 6528 functionally independent residents (3189 men and 3339 women aged ≥65 years living in four municipalities in Aichi prefecture. We used household income as an indicator of economic status. Multiple linear regression was used to compare serum albumin levels in relation to household income, which was classified as low, middle, and high. Additionally, mediation by nutritional and health-related factors was analyzed in multivariable models.With the middle-income group as reference, participants with low incomes had a significantly lower serum albumin level, even after adjustment for sex, age, residential area, education, marital status, and household structure. The estimated mean difference was -0.17 g/L (95% confidence interval, -0.33 to -0.01 g/L. The relation between serum albumin level and low income became statistically insignificant when "body mass index", "consumption of meat or fish", "self-rated health", "presence of medical conditions", "hyperlipidemia", or "respiratory disease "was included in the model.Serum albumin levels were lower in Japanese older adults with low economic status. The decrease in albumin levels appears to be mediated by nutrition and health-related factors with low household incomes. Future studies are needed to reveal the existence of other pathways.

    Full Text Available Background Leptin is a multifunctional hormone plays an important role in regulating lipid, energy, homeostasis, angiogenesis, inflammation, hematopoiesis and cell cycle. This polypeptide is effective in growth and differentiation of leukemic cells through an Ob-R receptor expressed by them. Objectives The purpose of this study was to evaluate serum leptin levels in patients with acute leukemia and compare it in lymphoid and myeloid groups. Patients and Methods This analytical case-control study, conducted on 60 children in age ranged from 6 months to 16 years in two case and control groups in Ali ibn Abi Talib hospital, Zahedan. They matched based on age and gender and examined after their parent’s satisfaction according to the parental consent forms. None of patients had heart disease, digestive, glandular and metabolic problems, iron deficiency anemia and chronic kidney disease. After collecting the samples, leptin levels of both groups were measured with ELISA kit. Then, the gathered data were analyzed in SPSS-20 software, using independent t-test in considering of 95% confidence interval. Results Leptin serum levels in patients with acute leukemia and controls showed significant difference (P < 0.05. Leptin serum levels in patients with acute lymphoblastic leukemia and acute myeloblastic leukemia showed significant difference (P < 0.05. Leptin serum level in relation to age and gender groups was not statistically significant. Conclusions The findings of this study showed that in patients with acute leukemia, leptin serum levels increase independently of age and gender. In addition, leptin serum levels in acute lymphoid leukemia were higher than acute myeloid leukemia in this study.

    Patients with advanced Parkinson's disease (PD) experience body weight loss and reductions in the most common cardiovascular risk factors. At present, the pathogenetic mechanisms involved have not been elucidated. Increased serum concentrations of adiponectin, which possesses antiatherogenic and anti-inflammatory properties, are associated with a reduction in cardiovascular risk. The objective of this study was to determine adiponectin serum concentrations in PD patients. Thirty PD patients underwent a full nutritional status assessment, including the determination of adiponectin serum concentrations. Mean ± SD adiponectin concentrations were 9.59 ± 5.9 μg/mL (interquartile range: 5.92-12.9 μg/mL). In PD patients, adiponectin serum levels were similar to those in normal-weight, healthy, young subjects and significantly higher than that in an aged-matched group of morbidly obese subjects. Further studies are warranted to establish the role of adiponectin in the management of PD patients.

    Objective To discuss the roles of serum interleukin-18 (IL-18), interleukin-10 (IL-10) and soluble interleukin-2R (sIL-2R) in the pathogenesis of chronic hepatitis C and to observe the effects of interferon (IFN) on the above- mentioned serum cytokines. Methods The levels of above- mentioned cytokines were detected in 10 healthy individuals, 24 asymptomatic hepatitis virus C (HCV) carriers and 27 patients with chronic hepatitis C ( before and after IFN treatment) using enzyme linked immunosorbent assay (ELISA). Results The levels of the cytokines in patients with chronic hepatitis C are higher than in healthy people (P<0.05) and in asymptomatic HCV carriers(P<0.05). The values of the cytokines show a significant positive correlation to ALT (P<0.05). Levels of tested cytokines decreased observably after IFN treatment (P<0.05). The grades of the serum levels for sIL-2R and IL-10 before IFN treatment (from high to low) were categorized accordingly: non-response group> partial- response group >complete- response group (P<0.05). Conclusions The tested cytokines co-participate in the pathogenesis of chronic hepatitis C, and can be used to evaluate the effect of IFN on the immune state of organisms. Furthermore, sIL-2R and IL-10 are important for predicting the anti-viral efficacy of IFN.

    Full Text Available Abstract Background There is mounting evidence that estimates of intakes of a range of dietary nutrients are related to both lung function level and rate of decline, but far less evidence on the relation between lung function and objective measures of serum levels of individual nutrients. The aim of this study was to conduct a comprehensive examination of the independent associations of a wide range of serum markers of nutritional status with lung function, measured as the one-second forced expiratory volume (FEV1. Methods Using data from the Third National Health and Nutrition Examination Survey, a US population-based cross-sectional study, we investigated the relation between 21 serum markers of potentially relevant nutrients and FEV1, with adjustment for potential confounding factors. Systematic approaches were used to guide the analysis. Results In a mutually adjusted model, higher serum levels of antioxidant vitamins (vitamin A, beta-cryptoxanthin, vitamin C, vitamin E, selenium, normalized calcium, chloride, and iron were independently associated with higher levels of FEV1. Higher concentrations of potassium and sodium were associated with lower FEV1. Conclusion Maintaining higher serum concentrations of dietary antioxidant vitamins and selenium is potentially beneficial to lung health. In addition other novel associations found in this study merit further investigation.

    Restless legs syndrome is characterised by discomfort during rest and an urge to move the limbs that is accompanied by abnormal sensations. Studies on disease pathophysiology have focused on dopaminergic dysfunction. Vitamin D may play an important role in dopamine function, but the role of vitamin D in restless legs syndrome has not been examined. We compared the serum vitamin D levels of RLS patients and matched controls and explored the correlation of plasma vitamin D levels with disease severity. We measured serum 25-hydroxyvitamin D levels in 36 patients with restless legs syndrome and compared them to 38 healthy control subjects. The mean serum 25-hydroxyvitamin D levels were 7.31±4.63 ng/mL in female patients with restless legs syndrome and 12.31±5.27 ng/mL in female control subjects (p=0.001). We found a significant inverse correlation between vitamin D levels and disease severity in females (p=0.01, r=-0.47). The mean serum vitamin D levels were lower in female patients with restless legs syndrome. Low vitamin D levels may cause dopaminergic dysfunction in restless legs syndrome patients. Further studies are required to confirm these results. Copyright © 2012 Elsevier B.V. All rights reserved.

    Inflammation is a common feature of both peripheral arterial disease (PAD) and periodontal disease. The aim of this study was to evaluate the relationship between PAD and periodontal disease by examining the levels of inflammatory cytokines (pentraxin 3 and interleukin 1β) and high sensitive C-reactive protein from gingival crevicular fluid and serum. A total of 60 patients were included in this cross-sectional study. Patients were divided into two groups based on ankle-brachial index values: with PAD (test group) and non-PAD (control group). Demographic evaluations, clinical periodontal examinations and biochemical analysis for pentraxin 3, interleukin 1β and high sensitive C-reactive protein were performed to compare the two groups. There were no significant differences with respect to gender, age, body mass index, or smoking history (duration, amount) between the two groups (p > 0.05). There were no significant differences between the two groups in terms of clinical periodontal parameters (p > 0.05). Neither gingival crevicular fluid nor serum levels of the cytokines showed differences between the two groups. Logistic regression analysis revealed that, after adjusting for confounding factors (age, gender, diabetes, hypertension and body mass index), periodontitis raised the odds ratio for having PAD to 5.842 (95% confidence interval: 1.558-21.909). Although there were no significant differences with respect to clinical periodontal parameters and biochemical analyses between the study group and control, periodontitis did raise the odds ratio for having PAD. To clarify this possible relationship, future prospective studies are needed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available BACKGROUND : Acute myocardial infarction (AMI is one of the major causes of mortality and morbidity in the world. Serum albumin levels are inversely related with age, smoking, blood pressure and obesity. It is not clear whether low serum albumin level is a nonspecific , prognostic variable, a marker of subclinical disease, or whether it is a part of causal mechanism leading to death due to cardiovascular disease. Some studies have reported an inverse association between serum albumin and cardiovascular mortality but oth ers have not . 1 The association between serum albumin and cardiovascular mortality remains controversial. This study was done to evaluate the serum albumin levels in patients with ST segment elevation Myocardial infarction (STEMI over a period of three days from the date of admission and whether the changes had any relationship with the prognosis of the patient. AIM: to associate changes in serum albumin levels in AMI patients over a period of three days i.e., day zero - at the time of admission, day+1 - the following day(12 to 30hrs after collecting first sample, day +2(32 to 54 hrs after collecting first sample with the clinical prognosis of the patient. SETTINGS AND DESIGN : Prospective follow up study in patents admitted with AMI in a tertiary care hospital. METHODS: 30 pati ents admitted with STEMI were included in the study and serum albumin levels were estimated in them on admission and for two days thereafter. Statistical analysis used. The data was analysed using SPSS 15.0, STATA 8.0, MEDLAC 9.0.1, And SYSTAT 11 softwares. Repeated measures analysis of variance and student t test was used to find the significance in changes of serum albumin levels and prognosis of the patient on different days. RESULTS AND CONCLUSION: This study found that there was fall in serum albumin le vels in patients with AMI in the course of three days compared with the day of admission and it was significantly associated with bad prognosis.

    Full Text Available Context : The preferential occurrence of idiopathic central serous chorioretinopathy (ICSC in males with a typical Type A personality and behavior and a relative absence in females is a possible indicator towards the role of serum cortisol and /or the male sex hormone testosterone. Aims : To study levels of cortisol and testosterone in ICSC. Settings and Design : Case-control study in a tertiary care teaching hospital. Materials and Methods : The study was conducted on 23 cases of ICSC. Twelve patients with unilateral sudden painless loss of vision of less than one month duration served as controls. Serum cortisol and testosterone levels at 8.00 a.m. were estimated by radioimmunoassay in both groups. Statistical analysis used : Statistical analysis was done using SPSS 13.0 software. Independent Sample t-test was applied to analyze statistical significance between the two groups. Results : Mean age of patients with ICSC was 37.1 ± 9.7 years and 96% of the patients were males. Mean serum cortisol levels were significantly higher (P=0.002 in patients with ICSC i.e., 495.02 ± 169.47 nano moles/liter (nmol/L as compared to controls i.e., 362.25 ± 51.54 nmol/L. Mean serum testosterone levels were 3.85 ± 1.81 nano grams/ml (ngm/ml and 4.23 ± 1.89 ngm/ml in cases and controls respectively and the difference was not statistically significant (P=0.58. Conclusions : ICSC is associated with elevated 8.00 a.m. serum cortisol levels. However, mean serum testosterone levels in both patients of ICSC and controls were within normal range.

    Erythropoietin has been shown to induce neovascularization and protect against ischemic vascular injury. We investigated whether a higher serum erythropoietin (EPO) level is related to better coronary collateral vessel grade. Ninety-nine patients with stable angina pectoris who have at least 1 coronary stenosis of equal to or greater than 70% at coronary angiography were prospectively enrolled. Serum EPO and vascular endothelial growth factor (VEGF) levels were studied. Coronary collateral degree was graded according to the Rentrop method. Patients with grade 2-3 collateral degree were included in the good collateral group and formed Group I. The patients with grade 0-1 collateral degree were included in the poor collateral group and formed Group II. The serum EPO level was significantly higher in the good collateral group (17.3 ± 9.3 mU/mL vs 11.7 ± 5.0 mU/mL; P < 0.001). There was also a positive correlation between serum EPO level and Rentrop score (r = 0.39; P < 0.001). In multivariate analysis, serum EPO level (odds ratio [OR] 1.336; 95% confidence interval [CI], 1.120-1.593; P = 0.001), oxygen saturation (OR 0.638; 95% CI, 0.422-0.963; P = 0.033) and presence of chronic total occlusion (CTO) (OR 26.7; 95% CI, 3.874-184.6; P = 0.001) were independently related to well-developed coronary collaterals. Higher serum EPO level is related to better coronary collateral development. Erythropoietin may have a positive effect on the development of collaterals and may provide a new agent for the treatment strategies to enhance coronary collateral vessel development.

    Interleukin (IL)-27 is an IL-12 family cytokine and exerts a critical role in immune regulation in the context of infection, autoimmunity, and angiogenesis. In this study, we aimed to investigate the possible pathophysiological role of IL-27 and vascular endothelial growth factor (VEGF) in ankylosing spondylitis (AS). One hundred and forty AS patients and 90 healthy controls were included in the current study. The levels of IL-27 and VEGF in serum and synovial fluid (SF) samples were measured by enzyme-linked immunosorbent assay. Erythrocyte sedimentation rate, C-reactive protein, and human leukocyte antigen (HLA)-B27 were measured by standard laboratory techniques. Disease activity in AS was scored with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Hip involvement, peripheral arthritis, and eye involvement were also recorded. The serum levels of IL-27 were remarkably higher in AS patients than healthy groups and significantly correlated with serum levels of VEGF. Furthermore, the serum levels of IL-27 were correlated with BASDAI independent of other markers of inflammation. Elevated serum levels of IL-27 and VEGF were detected in AS patients with peripheral arthritis and HLA-B27 positive. The SF levels of IL-27 and VEGF were significantly higher than serum levels in AS patients with peripheral arthritis. By contrast, levels of IL-27 and VEGF were not increased in AS patients with hip involvement and eye involvement. IL-27 may regulate the immunological or inflammatory process of AS.

    There have been many discrepant observations on the serum levels of cytokines in cancer patients and their prognostic value. The purpose of this study was to determine the plasma levels of pro- and anti-inflammatory cytokines and their clinical significance in a large group of patients with gastric carcinoma. The levels of tumour necrosis factor alpha (TNF alpha), interleukin-12p40 (IL-12p40), IL-12p70, IL-18, IL-10 and soluble TNF receptors I and II sTNF-Rs were investigated in the plasma of 136 consecutive patients with biopsy proven gastric cancer using specific enzyme-linked immunoabsorbent assays (ELISA). Survival curves were estimated using the method of Kaplan and Meier and the differences in the survival rates were tested by the log-rank test. For multivariate analysis of prognostic factors, the Cox proportional hazard model was used. Proinflammatory cytokines and sTNF-Rs were higher in the whole group of patients in comparison to healthy volunteers. IL-10 was elevated mostly in advanced disease. The increased levels of IL-10 (>10 pg/ml) were associated with significantly poorer survival of patients, while the levels of the other cytokines and sTNF-Rs showed no correlation with prognosis. The increased level of IL-10 is an independent unfavorable prognostic factor in patients with gastric cancer.

    Refeeding syndrome is a life-threatening condition occurring in severely malnourished patients after initiating feeding. Severe hypophosphatemia with reduced adenosine triphosphate production has been implicated, but little data are available regarding electrolyte abnormalities. In this case, we report electrocardiographic changes consistent with hyperkalemia during potassium replacement after a serum level increase from 1.9 to 2.9 mEq/L. This was reversed by lowering serum potassium back to 2.0 mEq/L. In conclusion, the patient with prolonged malnutrition became adapted to low potassium levels and developed potassium toxicity with replacement.

    Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

    This study evaluated the effects of LLLT on the expression of inflammatory cytokines related to the development of oral mucositis by gingival fibroblasts. Primary gingival fibroblasts were seeded on 24-well plates (10(5) cells/well) for 24 h. Fresh serum-free culture medium (DMEM) was then added, and cells were placed in contact with LPS (Escherichia coli, 1 μg mL(-1)), followed by LLLT irradiation (LaserTABLE-InGaAsP diode prototype-780 nm, 25 mW) delivering 0, 0.5, 1.5 or 3 J cm(-2)². Cells without contact with LPS were also irradiated with the same energy densities. Gene expression of TNF-α, IL-1β, IL-6 and IL-8 was evaluated by Real-Time PCR, and protein synthesis of these cytokines was determined by enzyme-linked immunosorbent (ELISA) assay. Data were statistically analyzed by the Kruskal-Wallis test, complemented by the Mann-Whitney test (P treatment increased the gene expression and protein synthesis of TNF-α, IL-6 and IL-8, while the expression of IL-1β was not affected. For LPS-treated groups, LLLT promoted significant decreases in the expression of TNF-α, IL-6, and IL-8 at 1.5 J cm(-2) and 3 J cm(-2). These results demonstrate that LLLT promoted a beneficial biomodulatory effect on the expression of inflammatory cytokines related to oral mucositis by human gingival fibroblasts.

    Full Text Available Adipose tissue produces a wide range of proteins that may influence the immune system. In this study, we assessed the serum levels of leptin, adiponectin, and ghrelin, in association with the measurements of body composition, in 15 female patients with various autoimmune diseases (systemic lupus erythematosus, primary Sjögren's syndrome, sarcoidosis, mixed connective tissue disease, vasculitis, CREST syndrome, and polymyositis and in 15 healthy female controls. There were no statistically significant differences between the patients and controls with regard to serum leptin, serum ghrelin, global fat mass, adiposity, and fat mass in the android or gynoid regions, whereas serum adiponectin levels were higher in patients than controls (16.3±1.6 μg/mL versus 9.7±0.6 μg/mL; =.01. As adiponectin is known to exhibit potent anti-inflammatory properties, a high adiponectinemia in patients with systemic autoimmune disease may mitigate the inflammatory response. However, the precise consequences of these elevated serum adiponectin levels on the metabolic syndrome development and atherosclerotic cardiovascular risk in this patient population still needs to be determined.

    Vitamin D is a modulator of both the innate and adaptive immune system. As vitamin D deficiency was a risk factor for some autoimmune diseases, we aimed to evaluate the serum vitamin D levels in autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) and investigated the association between serum vitamin D levels and AITD. 175 AITD patients including 51 GD, 61 euthyroid HT (mild HT), 63 euthyroid HT patients with hypothyroidism receiving hormone therapy (treated HT) were recruited from the outpatient department. 51 controls were from the physical checkup center of the hospital. 25-Hydroxyvitamin D levels, thyroid function, antithyroid antibodies, IL-4, IL-17, and TNF-α were determined. Compared with the controls, treated and mild HT patients had significantly lower 25(OH)D levels (45.77±3.48 vs. 83.49±6.24 nmol/L, p<0.001) and (55.25±3.88 vs. 83.49±6.24 nmol/L, p<0.001), respectively. However, GD patients had similar 25(OH)D levels (81.77±5.60 vs. 83.49±6.24 nmol/L, p=0.808). Compared to 24.1% controls with prevalent vitamin D deficiency, mild HT and treated HT patients were significantly different (55.4%, p<0.001) and (70.3%, p<0.001), respectively; no difference was seen in the GD patients (22.9%, p=0.797). Serum 25(OH)D levels were not associated with thyroid function, antithyroid antibodies, and serum cytokines IL-4, IL-17, and TNF-α in patients with AITD. We observed relatively low vitamin D level in mild and treated HT patients, while GD patients had similar 25(OH)D levels to those of healthy individuals. Further studies are imperative to explore the complex etiology of vitamin D deficiency in AITD.

    Background Defects in lymphoproliferative responses to mitogen/antigens in women >45 years old ith a persistent type-specific HPV infection have been reported. Methods To determine whether these defects were associated with altered cytokine profiles, plasma and PBMC culture supernatants from 50 cases (persistent HPV infection and weak lymphoproliferative responses) and 50 uninfected controls were examined for 24 cytokines using multiplexed bead-based immunoassays and enzyme-linked immunosorbent assay (ELISA). Results The following plasma cytokines were significantly increased from cases relative to controls: (cases vs. controls (median pg/ml); IL-6: 393.1 vs. 14.5, IL-8: 1128.5 vs. 43.9, TNF-α: 164.1 vs. 9.2, MIP-1α: 1368.9 vs. 25.5, GM-CSF: 13.8 vs. 7.3, IL-1β: 8.3 vs. 1.6, all p10) and highly statistically significant difference between cases and controls. Moreover, length of persistence or type of infection (high risk and low risk) did not affect these differences. IL-6, TNF-α, MIP-1α levels were increased in unstimulated PBMC culture supernatants from cases compared to controls (p <0.05), except for IL-8 (p=0.09). However, the cytokine levels from PHA-stimulated PBMC culture supernatants were significantly lower in the cases (p<0.0001). Conclusions Persistent HPV infection in older women with evidence of immune deficit is associated with an increase in systemic inflammatory cytokines. Impact Future studies are needed to determine whether the inflammatory profile is age dependent and to examine the role inflammatory cytokines play in HPV-induced progression from infection to cervical cancer.

    Chlorophytum arundinaceum, Asparagus adscendens and Asparagus racemosus are used in the Indian traditional system of medicine for improving the general state of health and for stress-related immune disorders. The effects of the methanol and aqueous extracts of the tuberous roots of these plants were examined in an experimental mouse model of stress, induced by swimming. The extracts were shown to exert an inhibitory effect on pro-inflammatory cytokines, namely interleukin 1β and tumour necrosis factor α, and on the production of nitric oxide in mouse macrophage cells RAW 264.7 stimulated by lipopolysaccharide in vitro. Similar inhibition was also observed in the production of interleukin 2 in EL 4 lymphoma cells stimulated by concanavalin A. Corticosterone levels in serum and adrenal glands were measured. The findings suggest that these plants may be beneficial in the management of stress and inflammatory conditions. Copyright © 2010 John Wiley & Sons, Ltd.

    Although several studies have shown an association between ferritin level and hypertension, only a few studies have investigated the longitudinal relationship between them. Thus, we evaluated the incidental risk for hypertension according to baseline ferritin level. A total of 7104 healthy Korean men matched by a propensity score, who had participated in a medical health check-up program in 2005, were followed up from 2005 to 2010. They were divided into four groups according to baseline serum ferritin level (first quartile-fourth quartile). The incidence of hypertension was compared among the four groups, and the Cox-proportional hazard model was used to assess whether the development of hypertension was associated with higher baseline serum ferritin level. A total of 1252 (17.6%) cases had newly developed hypertension during the 26,339.5 person-years of follow-up between 2006 and 2010. The adjusted hazard ratios (HRs) (95% confidence intervals, CIs) for incident hypertension were 1.00 (reference), 1.09 (0.91-1.30), 1.21 (1.01-1.45) and 1.28 (1.07-1.52), respectively (P for trend=0.003) through the quartiles of serum ferritin levels, respectively, after adjusting for multiple confounders. For the log-transformed serum ferritin levels as a continuous variable, adjusted HRs and 95% CIs for HTN were 1.15 (1.02-1.29). Elevated serum ferritin level was independently associated with the incidental risk for hypertension in Korean men. This finding suggests the value of elevated ferritin level as an early predictor of hypertension. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Acute otitis media (AOM) is an inflammatory response to microbes in the middle ear, sometimes associated with rupture of the tympanic membrane. Human leukocytes produce different patterns of inflammatory mediators in vitro when stimulated with Gram-positive and Gram-negative bacteria, respectively. Here, we investigated the cytokine and prostaglandin E2 (PGE2) responses in middle ear fluids (MEFs) from children with spontaneously perforated AOM, and related the mediator levels to the presence of pathogens detected by culture (live) or PCR (live or dead). Furthermore, the in vivo cytokine pattern was compared with that induced in leukocytes stimulated by dead bacteria in vitro. MEFs with culturable pathogenic bacteria contained more interleukin (IL)-1β (median: 110 μg/L vs. bacteria. Cytokine levels were unrelated to bacterial species and to the presence or absence of virus. Similar levels of TNF and IL-6 as found in the MEFs were obtained by in vitro stimulation of leukocytes, whereas 11 times more IL-1β and 3.5 times more IL-8 were produced in vivo, and 22 times more IL-10 was produced in vitro. Vigorous production of proinflammatory cytokines accompanies AOM with membrane rupture, regardless of the causative agent, but the production seems to cease rapidly once the bacteria are killed and fragmented. IL-6 and PGE2, however, remain after bacterial disintegration, and may play a role in the resolution phase.

    Objective To explore the metabolism of vitamin A and the influence of vitamin A on the balance of helper T-lymphocyte (Th) 1/Th2 in children with type 1 diabetes mellitus (T1DM). Methods A total of 32 children with T1DM were chosen, and 28 healthy children were taken as control. The serum level of vitamin A was determined by the micro-fluorescence method, and the serum level of C-peptide and the level of HbA1C were determined by chemoluminescence assay and laser nephelometry, respectively. Peripheral blood mononuclear cells (PBMC) were isolated from venous blood of children with T1DM and normal children under the aseptic condition. The cell suspension of PBMC from T1DM children were divided into two aliquots, one aliquote was assigned to vitamin A intervention group and another to the non-intervention group. The supernatant was collected after 48 h of culture in vitro. The levels of IFN-γ and IL-4 in the supernatant were determined by enzyme-linked immunosorbent assay. Results The levels of vitamin A and C-peptide in T1DM children were lower than those in control group (P<0.01). The level of HbA1C in T1DM children was higher than that in control group (P<0.01). The serum concentration of vitamin A was positively correlated with the serum level of C-peptide in T1DM children (r=0.356, P<0.05), and negatively correlated with the level of HbA1C (r=-0.394, P<0.05). In vitro, IFN-γ level produced from PBMC in T1DM children was higher than that in control group (P<0.05), and IFN-γ/IL-4 ratio was also higher than that of control group (P<0.01).The level of IFN-γ produced from PBMC in vitamin A intervention group was lower than that in non-intervention group (P<0.01), and IFN-γ/IL-4 ratio was also lower than that of non-intervention group (P<0.01). Conclusions Vitamin A can restore the balance of Th1/ Th2 in children with type 1 diabetes mellitus.%目的 探讨1型糖尿病 (T1DM) 患儿体内维生素A的代谢情况及维生素A对T1DM患儿辅助性T淋巴细胞 (Th

    2016-02-01

    Full Text Available Postmenopausal women are at high risk of disease, such as coronary heart disease, stroke, malignancies, dementia and osteoporosis. This is due to decreased levels of estrogen/estradiol, produced mainly in the ovaries, leading to reduced bone mineral density (BMD, which is the gold standard for diagnosis of osteoporosis. The purpose of the present study was to determine the relationship between serum estradiol levels and BMD in postmenopausal women. The study, which was of cross-sectional design, involved 184 postmenopausal women meeting the inclusion criteria, viz. healthy postmenopausal women aged between 47 and 60 years having taken no hormonal medications in the previous 3 years. The subjects were assessed for anthropometric and biochemical characteristics, including BMD and serum estradiol levels. BMD was measured at the lumbar spine, right femoral neck and at the distal radius by the dual-energy X-ray absorptiometry (DXA instrument. The mean serum estradiol concentration was 7.54 ± 4.65 pg/ml, while in 49.5% of the subjects the estradiol concentration was £ 5 pg/ml. In postmenopausal women with estradiol concentrations of > 5 pg/ml, a significant positive relationship was found between BMD and the T-scores for the femoral neck. Thus the higher the serum estradiol levels, the higher the BMD values for femoral neck region. In conclusion, the results of this study point to estradiol levels as a major factor in determining the BMD values in postmenopausal women.

    Full Text Available "nFebrile seizure is the most common type of seizure in children and a variety of causes are considered to be responsible for it. There are some reports that zinc may have a role in febrile seizure. The aim of this study was to compare the serum zinc level in children with and without febrile seizure. In this case-control study, 52 children with febrile seizure compared with 52 healthy children based on serum zinc level. Both groups were matched for age, sex, weight, height, and head circumference. The age range of children was 9 months to 5 years. Serum zinc level was measured using flame atomic absorption spectrophotometry. Of 52 children in case group, 30 (57.7% were male and 22 (42.3% female and among the control group, there was 31 (59.9% males and 21 (40.4% females. The mean age of children in case group was 27.13 ± 15.72 and in control group 28.49 ± 16.5 months. The mean zinc level in case group was 62.84 ± 18.40 mg/dl and in control group 85.70 ± 16.76 (P < 0.05. This study revealed that the serum zinc level in children afflicted with their first febrile seizure is lower than in healthy children and the difference is statistically significant. It seems that the zinc deficiency may play a role in febrile seizure.

  15. Maternal Serum Meteorin Levels and the Risk of Preeclampsia.

    Full Text Available Meteorin (METRN is a recently described neutrophic factor with angiogenic properties. This is a nested case-control study in a longitudinal cohort study that describes the serum profile of METRN during different periods of gestation in healthy and preeclamptic pregnant women. Moreover, we explore the possible application of METRN as a biomarker.Serum METRN was measured by ELISA in a longitudinal prospective cohort study in 37 healthy pregnant women, 16 mild preeclamptic women, and 20 healthy non-pregnant women during the menstrual cycle with the aim of assessing serum METRN levels and its correlations with other metabolic parameters. Immunostaining for METRN protein was performed in placenta. A multivariate logistic regression model was proposed and a classifier model was formulated for predicting preeclampsia in early and middle pregnancy. The performance in classification was evaluated using measures such as sensitivity, specificity, and the receiver operating characteristic (ROC curve. In healthy pregnant women, serum METRN levels were significantly elevated in early pregnancy compared to middle and late pregnancy. METRN levels are significantly lower only in early pregnancy in preeclamptic women when compared to healthy pregnant women. Decision trees that did not include METRN levels in the first trimester had a reduced sensitivity of 56% in the detection of preeclamptic women, compared to a sensitivity of 69% when METRN was included.The joint measurements of circulating METRN levels in the first trimester and systolic blood pressure and weight in the second trimester significantly increase the probabilities of predicting preeclampsia.

    Full Text Available Severe sepsis and trauma complicated with multiple organ dysfunction syndrome (MODS are among the leading causes of death in intensive therapy units with mortality rate exceeding 50%. The outcome is not determined only by infection or trauma, but also by the intensity of immuno-inflammatory response, which is essential for host defence, but if uncontrolled leads to MODS. Pro-inflammatory cytokines (tumor necrosis factor-a -TNF-a, IL-1 IL-8, IL-12, IFN-g, etc represent a part of this immuno-inflammatory response to an insult. The results of the clinical investigation of correlation between pro-inflammatory cytokines (IL-8, IL-12, TNF-a, IFN-g the outcome (survivors, non-survivors, and the severity (systemic inflammatory response syndrome - SIRS - less severe, and MODS - more severe in polytraumatised patients with sepsis are presented in this paper. Mean values of IL-8 were 1.3-fold higher in non-survivors (p<0.05, and 60-fold higher in MODS group (p<0.01. Mean values of IL-12 were 1.6-fold higher in survivors (p<0.01, while the values between SIRS and MODS group did not differ significantly; mean values of TNF-a were 3-fold higher in survivors (p<0.05, and 46-fold higher in MODS group (p<0.01. Mean values of IFN-g did not differ significantly between the two groups regarding the outcome and severity. The obtained results indicated that IL-8 was a reliable predictor of lethal outcome and MODS (p<0.01, IL-12 a reliable predictor of survival (p<0.05, and TNF-a a reliable predictor of survival (p<0.05 and MODS (p<0.01.

    Electromagnetic pulse (EMP) was a potentially harmful factor to the human body, and a biological dosimetry to evaluate effects of EMP is necessary. Little is known about effects of EMP on concentration of macro and trace elements in serum so far. In this study, Sprague-Dawley rats were randomly divided into 50-kV/m EMP-exposed group (n = 10), 100-kV/m EMP-exposed group (n = 10), 200-kV/m EMP-exposed group (n = 40), and the sham-exposed group (n = 20). The macro and trace element concentrations in serum were examined at 6, 12, 24, and 48 h after EMP exposure at different electric field intensities. Compared with the sham-exposed groups, the concentration of sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), iron (Fe), selenium (Se), and manganese (Mn) in rat serum was not changed significantly within 48 h after 200 pulses of EMP exposure at electric field intensity of 50, 100, and 200 kV/m although the K level was decreased and the Ca level was increased with the electric field intensity of EMP increasing. In addition, there was a tendency that the Zn level was decreased with the time going on within 48 h after EMP exposure. Under our experimental conditions, EMP exposure cannot affect the concentration of macro and trace elements in rat serum. There was no time-effect or dose-effect relationship between EMP exposure and serum element levels. The macro and trace elements in serum are not suitable endpoints of biological dosimetry of EMP.

Erythropoietin levels were measured in umbilical cord sera of 60 newborns who were delivered vaginally at term. There were 20 (33% smoking and 40 (67% nonsmoking mothers. Results. Mean cord serum erythropoietin levels were significantly lower in the nonsmokers (nonsmokers, 24 ± 9 IU/L; smokers, 61 ± 46 IU/L; P<.001. There was a significant positive correlation between the number of cigarettes smoked per day and cord serum erythropoietin levels (r, 0.58; P≤.05. Conclusions. Smoking during pregnancy is associated with increased levels of umbilical cord erythropoietin at birth. This may indicate a risk of fetal hypoxia and growth restriction. Education and encouragement of cessation of smoking during pregnancy are important to avoid associated fetal and maternal morbidity and mortality.

    This study tested the hypothesis that the diurnal variations of serum-erythropoietin concentration (serum-EPO) observed in normoxia also exist in hypoxia. The study also attempted to investigate the regulation of EPO production during sustained hypoxia. Nine subjects were investigated at sea level...... and during 4 days at an altitude of 4350 m. Median sea level serum-EPO concentration was 6 (range 6-13) U.l-1. Serum-EPO concentration increased after 18 and 42 h at altitude, [58 (range 39-240) and 54 (range 36-340) U.l-1, respectively], and then decreased after 64 and 88 h at altitude [34 (range 18......-290) and 31 (range 17-104) U.l-1, respectively]. These changes of serum-EPO concentration were correlated to the changes in arterial blood oxygen saturation (r = -0.60, P = 0.0009), pH (r = 0.67, P = 0.003), and in-vivo venous blood oxygen half saturation tension (r = -0.68, P = 0.004) but not to the changes...

    Infections are common in preterm infants and cause differences in cytokine levels. Aim of this study was to measure cytokine levels in preterm infants during the first year of life and to determine the effect of feeding a specific non-digestible carbohydrate mixture (scGOS/lcFOS/pAOS). Furthermore, other perinatal factors in relation to these cytokine levels were analysed. In a randomized controlled trial, preterm infants (GA Cytokine levels (IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-17, IFN-γ, and TNF-α) were analysed at 5 time points during the study: before start of the study, at day 7, at day 14 and at 5 and 12 months after the start of the intervention. In total, 55 preterm infants in the scGOS/lcFOS/pAOS group and 58 in the placebo group were included. During the neonatal period cytokine levels increased, followed by a decrease at 5 months and 12 months. Enteral supplementation of the non-digestible oligosaccharides decreased cytokine levels at day 7 but not at day 14, indicating a temporarily anti-inflammatory effect. In the neonatal period, serious infection before sampling increased all cytokine levels. In conclusion, enteral supplementation of this specific non-digestible oligosaccharide mixture decreased cytokine levels in preterm infants at day 7 of life, although this effect disappeared thereafter.

    Full Text Available Background/Aims: Hyperuricemia has been reported to affect renal hemodynamics in rat models. We evaluate the relationship between serum uric acid and intrarenal hemodynamic parameters in humans, utilizing the plasma clearance of para-aminohippurate (CPAH and inulin (Cin. Methods: Renal and glomerular hemodynamics were assessed by simultaneous measurement of CPAH and Cin in 58 subjects. Of these, 19 subjects were planned to provide a kidney for transplantation; 26 had diabetes without proteinuria; and 13 had mild proteinuria. Renal and glomerular hemodynamics were calculated using Gomez`s formulae. Results: Cin was more than 60 ml/min/1.73m2 in all subjects. Serum uric acid levels correlated significantly with vascular resistance at the afferent arteriole (Ra (r = 0.354, p = 0.006 but not with that of the efferent arteriole (Re. Serum uric acid levels (β = 0.581, p = a after adjustment for several confounders (R2 = 0.518, p = Conclusions: These findings suggest, for the first time in humans, that higher serum uric acid levels are associated significantly with Ra in subjects with Cin > 60 ml/min/1.73m2. The increase in Ra in subjects with higher uric acid levels may be related to dysfunction of glomerular perfusion.

    Full Text Available Inflammatory processes are involved in the pathogenesis and development of chronic heart disease. The promising novel inflammatory biomarker YKL-40 is related to the degree of inflammation and pathological tissue remodeling. The aim of this study was to determine serum YKL-40 levels in patients with chronic heart failure and to evaluate the potential relationship with ultrasonography findings. Forty-three individuals were enrolled in the study – 24 patients (10 females and 14 males with chronic heart failure, aged 70±11 (mean ± standard deviation and 16 healthy people as age-matched controls (above 50 years. The serum YKL-40 levels were assessed by ELISA. Sonographic measurements such as two-dimensional, Power wave, Continuous Wave, Colour mode and M-Mode were performed using a diagnostic ultrasound system (PHILIPS Ultrasound, Washington, US with a L11-3 probe of 3-11 MHz. The six minute walk test was used to assess functional capability of patients. Our study revealed significantly higher serum YKL-40 levels in patients compared to the control group (P=0.010. No relation was found between the glycoprotein and the results from the ultrasonographic and functional examination. We suppose that increased serum YKL-40 levels in patients with chronic heart failure might reflect the inflammatory route in the development of the disease.

    The aim of the present study was to investigate the role of sexual hormones in a young adult population affected by articular forms of temporomandibular disorders (TMD), measuring 17beta-estradiol and progesterone serum levels. In the study, we included 40 patients (20 males and 20 females) with a Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) axis I group II diagnosis of disk displacement and/or group III diagnosis of arthralgia, osteoarthritis or osteoarhrosis, and 32 healthy controls. In female patients, blood samples were collected in follicular and luteal phases of the same menstrual cycle, while only one blood sample was drawn in male patients. Serum levels of estradiol and progesterone were determined using a radioimmunoassay and the comparison between the two groups was performed using a t test. Regarding estradiol, our results showed significantly higher serum levels in patients affected by TMD than in healthy controls, both in males (p hormones, these data suggest that high serum estrogen levels might be implicated in the physiopathology of TMD.

    Full Text Available Abstract Background Members of the United States Armed Forces receive a series of vaccinations during their course of service. To investigate the influence of multiple vaccinations on innate immunity, we measured concentrations of a panel of immunomodulatory and pro-inflammatory cytokines in serum samples from a group of such individuals. Results Significantly increased levels of macrophage inflammatory protein 1α (MIP-1α, MIP-1β and interleukin 8 (IL-8 were detected. Since these cytokines are known to have anti-human immunodeficiency virus (HIV activity, we tested the effect of serum from these individuals on HIV-1 infectivity and susceptibility of their peripheral blood mononuclear cells (PBMCs to HIV-1 infection in vitro. Sera from vaccinated military personnel inhibited, and their PBMCs were partially resistant to, infection by HIV-1 strains tropic to CCR5 (R5, but not to CXCR4 (X4, chemokine receptor. Conclusion These findings demonstrate that increased anti-HIV chemokines can be detected in vaccine recipients up to 68 weeks following immunization.

    Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive correlation between BMI with fasting serum glucose and

    In order to clarify the role of tryptophan in the patogenesis of senile cataract, we have studied the serum total and free levels of tryptophan in cataract patients as compared with age and sex-matched controls, and the urinary excretion of 10 metabolites after oral load of the amino acid. This excretion increases in the cataract group both as total per cent and as kynurenine. No difference has been found in the free and total serum tryptophan between normal subjects and cataract patients. A possible role of the kynurenines in the pathogenesis of senile cataract is suggested.

    Full Text Available In the current study, it was aimed to investigate the roles of tissue cellular immunity and serum levels of cytokines in the patients with plaque psoriasis treated with calcipotriol-betamethasone dipropionate.Materials and methods: The study included 20 patients with psoriasis. Peripheral blood and biopsy samples were collected from lesional and normal skins before and after treatment. The results were compared with each other.Results: Immunohistochemical examination revealed significant elevations of CD4+, CD8+ and CD25+ T lymphocytes in the lesional tissues when compared to that in the healthy tissues and post treatment tissue (p0.05. The levels of IL–4, IL–10, TNF-α, IFN-γ and TGF-β1 in serum were not significantly different between before and after treatment periods (p>0.05.Conclusion: Our study demonstrated that there were infiltration of CD4+ and CD8+ cell in the lesional skin and CD8+ T-lymphocytes were the dominant cell types. The improvement of the lesions and significant decreases in CD4+ and CD8+ T-cells in accordance with the treatment strongly support the hypothesis that Th lymphocytes may have prominent roles in the immunopathogenesis of the disease. However, our findings showed that sufficient T-cells still remains in the tissue, which is consistent with the chronic characteristic of the disease, and the topical treatment could not be able to prevent the activation of the disease.

    Infection with many encephalitic viruses is associated with the induction of the proinflammatory cytokine interleukin (IL)-6. In some situations, induction of high levels of this cytokine is associated with a protective response, but in others it can be linked to tissue damage and disease. In the studies reported here, levels of serum IL-6 and virus-specific antibodies were measured on admission to hospital and correlated with clinical outcomes. Only some patients demonstrated raised levels of serum IL-6, and there was no correlation between high levels of this cytokine and either gender or the severity of clinical disease. A statistically significant association between raised IL-6 and age was observed, with all individuals below the age of 26 showing normal levels of serum IL-6, regardless of clinical presentation. Furthermore, not all patients had detectable levels of virus-specific serum immunoglobulin G (IgG) antibodies, but an inverse and statistically significant correlation between raised IL-6 levels and IgG titre was observed. Consequently, serum levels of IL-6 cannot be used as a reliable indicator of disease outcome. PMID:18462209

    Full Text Available Background Clinical and biochemical impacts on liver dysfunction, as manifested by an increase in serum transaminase levels, are common in dengue infection. However, an association of elevated serum transaminase and dengue shock syndrome (DSS has not been well-established. Objective To assess for an association between serum transaminase levels and the presence of DSS in children. Methods A nested, case control study was conducted on children aged 1 month to 12 years admitted to Sanglah Hospital who were diagnosed with dengue infection. Baseline characteristics and serum transaminase levels were recorded. Patients who were included in the study were observed for the presence of DSS. Those who had DSS were selected as cases, and those who did not develop DSS were selected as controls. Data was analyzed using bivariate and multivariate methods with 95% confidence intervals and P value <0.05 was considered as statistically significant. Results Ninety-four children were involeved, 47 children in the case group and the other 47 were in the control group. Baseline characteristics of the subjects were similar between the case and control groups. Serum aspartate transaminase (AST level of ≥128 U/L and alanine transaminase (ALT of ≥40 U/L were associated with DSS (OR 10; 95%CI 2.3 to 44.4; P=0.002 and (OR 7.3; 95%CI 1.6 to 32.9; P=0.009, respectively. Conclusion Elevated AST and ALT levels were associated with an increased risk of DSS in children with dengue infection

    Full Text Available Aim: to investigate the serum levels of TNF-α, IL-8, VEGF in Helicobacter pylori infection, and their association with the degrees of gastritis histopathology. Methods: a cross-sectional study was done on 80 consecutive gastritis patients admitted to endoscopy units at Adam Malik General Hospital and Permata Bunda Hospital, Medan, Indonesia from July-December 2014. The Rapid Urease test was used for the diagnosis of H. pylori infection. The severity of chronic inflammation, neutrophil infiltration, atrophy, and intestinal metaplasia were assessed. Serum samples were obtained to determine circulating TNF-α, IL-8, and VEGF. Univariate and bivariate analysis (chi square, fisher’s exact, and mann-whitney test were done using SPSS version-22. Results: there were 41.25% of 80 patients infected with Helicobacter pylori. Serum TNF-α and VEGF levels in the infected group were significantly higher compared to H. pylori negative, but there were no significant differences between serum levels of IL-8 in H. pylori positive and negative. There were significant associations between serum level of TNF-α and IL-8 with degree of chronic inflammation, and also between serum level of IL-8 and degree of neutrophil infiltration. There were significant associations between serum level of VEGF and degree of atrophy, and also between serum level of VEGF and degree of intestinal metaplasia. Conclusion: High levels of TNF-α were associated with severe degree of chronic inflammation, high levels of IL-8 associated with severe degree of chronic inflammation and neutrophil infiltration, and high levels of VEGF associated with severe degree of premalignant gastric lesion. Key words: cytokine, neoangiogenesis, Helicobacter pylori, atrophic gastritis, intestinal metaplasia.

    Porcine pleuropneumonia is a severe respiratory disease caused by Actinobacillus (A.) pleuropneumoniae. The aim of the present study was to analyze serum samples of A. pleuropneumoniae-infected pigs for TNF-α, IL-1β and IL-6 using a cytometric bead array (CBA) 3-plex assay and additionally for IL-6 using ELISA. The CBA 3-plex assay was successfully validated for use in serum. The limits of detection varied between 0.012 and 0.333 ng/mL, and the inter- and inter-assay coefficients of variation were pleuropneumoniae. Mean peak concentrations of TNF-α and IL-6 were recorded at 12h and at 10h p.i., respectively. For IL-6, similar concentration-time profiles were observed with CBA and ELISA. It is proposed that this immuno-assay can be applied for the screening of immunomodulatory properties of drugs and vaccine adjuvants in infection, inflammation and vaccination.

    Full Text Available SUMMARY The role of trace elements in dengue virulence is not yet known. The present study assessed the serum levels of two micronutrients, copper and iron, in cases of dengue fever. The study involved 96 patients of whom 48 had either severe or non-severe forms of dengue (with and without warning signs, and the remaining 48 were patients with other febrile illnesses (OFI, used as controls. Serum levels of copper and iron were evaluated at admission and by the time of defervescence using commercially available kits. At admission, no difference in the level of serum copper was observed between cases and controls. In the group of dengue cases, the copper level was found to be significantly decreased in severe and non-severe cases with warning signs, compared to non-severe cases without warning signs. In contrast, by the time of defervescence the copper level was found to be increased in all dengue cases compared to OFI controls, but no difference was observed among dengue cases. Unlike OFI controls, dengue cases showed an increasing pattern of copper levels from admission until defervescence. On the other hand, no such significant differences were observed in the serum level of iron in the clinical groups, except for a decreased iron level found in severe cases, compared to non-severe dengue without warning signs. The results show that copper is associated with dengue severity and this finding emphasizes the need to investigate the involvement of trace elements in disease severity so as to improve the prognosis of dengue.

Materials and Methods: Serum prohepcidin and ferritin levels were determined in 34 patient with TM, 10 patient with TI, who attended the Department of Pediatric Hematology Adnan Menderes University Medical Faculty and the Department of Pediatrics at Aydın Atatürk State Hospital between 1 September 2006 and 30 September 2007 and 40 control patients without infection/inflammation, hepatitis or liver failure. Serum prohepcidin levels were measured using a commercial enzyme-linked immunosorbent assay kit (DRG International, Inc. Marburg, Germany; ferritin was studied with chemiluminescence method (Immulite 2000 DPC. Results: Mean serum ferritin levels in TM, TI and control groups were 2347.97±1724.81 ng/mL (range: 144-8015 ng/mL, 1352.40±918.94 ng/mL (range: 311-3109 ng/mL, and 33.35±12.03 ng/mL (range: 20-69.1 ng/mL, respectively. Serum prohepcidin levels in the same groups were 221.78±74.38 ng/mL (range: 7l.14-446.57 ng/mL, 173.31±52.14 ng/mL (range: 100.83-267.69 ng/mL, and 218.20±50.37 ng/mL (range: 116.18-330.43 ng/mL, respectively. There was a statistically significant difference in prohepcidin levels between patients with TI and control group only (p=0.016. No correlation was found between prohepcidin and ferritin levels in all groups (r=-0.023, p=0.839. Conclusion: Low levels of prohepcidin in patients with TI may be related to increased erythropoietic activity. Prohepcidin can be an indicator of active erythropoiesis.

    Acute urticaria is an immune-inflammatory disease, characterised by acute immune activation. There has been increasing evidence showing that vitamin D deficiency is associated with increased incidence and severity of immune-inflammatory disorders. The aim of this study was to evaluate serum vitamin D levels in acute urticaria. We enrolled 30 children with acute urticaria and 30 control subjects. Concentrations of 25-hydroxyvitamin D [25(OH)D], a biomarker of vitamin D status, were measured in serum of acute urticaria patients and compared with the control group. There were no significant differences in baseline variables (age, gender, weight) between the groups. Vitamin D deficiency (urticaria than in control patients. Serum 25(OH)D levels were significantly lower in the study group compared to those in the control group (13.1±4.3 vs 28.2±7.4ng/mL, purticaria and serum vitamin D levels (purticaria and an inverse relationship with disease duration. These findings may open up the possibility of the clinical use of vitamin D as a contributing factor in the pathogenesis of acute urticaria and a predictive marker for disease activity in acute urticaria. A potential role of vitamin D in pathogenesis and additive therapy in acute urticaria needs to be examined. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

    AIM: To explore the role of ghrelin in gallstone disease.METHODS: We carried out a cross-sectional study in 150 subjects, 38 with gallstones (cases) and 112 controls. We also did a real-time PCR-RT study in twenty gallbladder samples each. Body mass index (BMI),serum insulin, ghrelin, and serum lipids were measured.Logistic regression analyses (univariate and multivariate) were conducted to estimate the probability of gallstone disease associated with serum ghrelin concentrations.RESULTS: Cases were statistically different from controls in gender distribution (P = 0.01), age (53 vs 44 yr, P = 0.002), BMI (28 vs 25; P = 0.004), and glucose (5.26 vs 4.98 mmol/L; P = 0.05). The prevalence of ghrelin serum levels above the third tercile was lower in subjects without metabolic syndrome (P < 0.05). In a multivariate model, we found a protective effect, when ghrelin values were higher than the median value (OR = 0.27, 95%CI 0.09-0.82, P = 0.02). Twenty (20%) gallbladder specimens expressed ghrelin mRNA.CONCLUSION: Serum ghrelin concentrations are associated with a protective effect of GD.

    The aim of this study was to determine the effects of drugs used in the treatment of endotoxaemia on disseminated intravascular coagulation, cytokine levels and adenosine deaminase activities in endotoxaemic rats. Rats were divided into seven groups. Lipopolysaccharide (LPS) was injected into all groups, including the positive control group. The other six groups received the following drugs: enrofloxacin (ENR), flunixin meglumine (FM), low-dose dexamethasone (DEX), high-dose DEX, ENR + FM + low-dose DEX, and ENR + FM + high-dose DEX. After the treatments, serum and plasma samples were collected at 0, 1, 2, 4, 6, 8, 12, 24 and 48 hours (h). A coagulometer was used to determine the levels of coagulation values, while ELISA was used to assay serum cytokines and adenosine deaminase (ADA). Low-dose DEX alone and combined treatments depressed the levels of cytokines and ADA (from 371 to 70 IU/L at 6 h) significantly and inhibited the decrease of coagulation values (antithrombin from 67 to 140% at 6 h, fibrinogen from 54 to 252 mg/dL at 6 h). In summary, FM + high-dose DEX may be the preferred treatment of endotoxaemia because of its highest effectiveness. FM plus high-dose DEX may be a new therapy for endotoxaemic domestic animals.

    Our previous studies showed that serum calcium level may have influence in the blood pressure to older male subjects, but the relationship between serum calcium level and blood lipids is unclear. The aim of this study was to evaluate the relationship between total serum calcium level and blood lipids. In our study, total serum calcium level and blood lipids were measured among 1,075 subjects, with age range of 30-60 years, who were recruited for the routine health screening in 2006. The results showed that serum calcium level was positively correlated with triglyceride and total cholesterol weight, but not HDL-cholesterol and LDL-cholesterol in female subjects (P 0.05). These findings suggest that a higher total serum calcium level may have a adverse effects on serum cholesterol and triglycerides among female subjects.

    Alterations of trace element concentrations adversely affect biological processes and could promote carcinogenesis. Only a few studies have investigated the degree of changes in copper and zinc levels in colorectal cancer (CRC). The aim of the present study was to compare the serum copper (Cu) and zinc (Zn) concentrations in patients with CRC from Iran with those of healthy subjects. Cu and Zn concentrations in the serum of 119 cancer patients and 128 healthy individuals were measured by atomic absorption spectrometry. We found a significant decrease in the total mean serum Cu and Zn concentrations in CRC patients as compared with the control group (137.5 ± 122.38 vs. 160.68 ± 45.12 μg/dl and 81.04 ± 52.05 vs. 141.64 ± 51.75, respectively). However, the serum Cu/Zn ratio in the patient group was significantly higher than that measured in the control group (p = 0.00). There was no significant difference in the mean values of serum Cu and Zn concentrations between young (obese cases (132.31 ± 87.43 vs. 103.81 ± 53.72 μg/dl, respectively) (p < 0.05). There was no difference in mean serum Cu and Zn concentrations in patients stratified by the site, stage, or differentiation grade of tumors. Our findings suggest that imbalance in Cu and Zn trace element level is associated with CRC and might play an important role in cancer development among Iranian patients.

    Studies on cytokine levels in Weil's syndrome are lacking. In this study, TNF-α, sTNFR1, IL-6, IL-8 and IL-10 levels were measured in 44 serum samples of patients diagnosed with Leptospira interrogans serovar icterohaemorrhagiae infection. TNF-α levels linked with pulmonary hemorrhagic implications, while elevated sTNFR1 and IL-10 levels linked with fatal cases. IL-6 and IL-8 did not seem to affect the outcome of the disease. Immune response pattern in Weil's syndrome bears resemblance to other patterns described for hemorrhagic fevers. IL-10/TNF-α ratio is proposed as a marker for prognosis.

    Sleep deprivation has been reported to decrease testosterone levels but the mechanism remains unclear. Studies have shown that sleep deprivation increases interleukin 1 beta (IL-1β), a pro-inflammatory cytokine and that increased IL-1β levels cause reductions in Leydig cell production of testosterone. This study was therefore designed to determine the effects of methotrexate, an IL-1β blocker on serum testosterone levels in sleep deprived male Wistar rats. Twenty male Wistar rats were randomly assigned into four groups (n = 5); group I (Control) received the vehicle (1% tween 80 solution); group II (methotrexate) received 0.5 mg/kg body weight methotrexate; group III (SD) was sleep deprived and received the vehicle; group IV (SD+Methotrexate) was sleep deprived and received 0.5 mg/kg body weight methotrexate. Sleep deprivation was induced using the modified multiple platform technique for 14 days. Treatments were administered twice weekly by oral gavage for 14 days. Blood was collected on day 14 and serum was obtained for analyses of testosterone, LH and FSH levels. IL-1β level and histology of the testis were also determined. Data were expressed as Mean ± SEM and analysed using ANOVA. p sleep deprived rats is not dependent on increased level of IL-1β.

    Full Text Available INTRODUCTION Gallstones are one of the most common problem associated with the gallbladder, affecting millions of people throughout the world. Bile is excreted from liver and gallbladder into Duodenum for digestion. After digestion, if the gallbladder is not emptied out completely, the Bile Juice that remains in the gallbladder can become too concentrated with cholesterol leading to gallstone formation. Cholesterol and calcium bilirubinate are the two main substances involved in gallstone formation. Gallstones derived from bile consists of mixture of cholesterol, bilirubin with or without calcium. Based on their chemical composition, gallstones found in the gallbladder are classified as cholesterol, pigmented or mixed stones. Iron deficiency has been shown to alter the activity of several hepatic enzymes, leading to increased gallbladder bile cholesterol saturation and promotion of cholesterol crystal formation. AIMS & OBJECTIVE Attempt to establish a correlation with gallstones and decreased serum iron levels. MATERIAL & METHODS This study was a prospective cohort study which included 100 consecutive patients with imaging studies suggestive of Cholelithiasis. The Gallstone surgically removed was crushed with mortar and pestle and then analysed for cholesterol, calcium, phosphate and bilirubin (pigment. Serum samples were analysed for Cholesterol, iron and iron binding capacity. RESULTS 86% patients had increased cholesterol levels (p=0.04 and 93% had decreased serum Iron levels (p=0.96. The most common type of gallstone was found to be Cholesterol type of gallstone followed by Mixed and Pigment gallstones. CONCLUSION Serum cholesterol levels were found to be raised in majority of the patients and serum iron was found to be low in these majority of the patients indicating iron deficiency may play a role in gallstone formation.

    Full Text Available Aging is associated with a gradual impairment in cognitive function. The elderly also show a high prevalence of undernutrition, whereas nutrition plays an important role in the metabolism of neuronal cells and enzymes. Homocysteine is an amino acid resulting from methionine metabolism and is dependent on intake of vitamin B12, vitamin B6 and folic acid. Homocysteine is said to play a role in cognitive function. The objective of this study was to evaluate the effect of micronutrient supplementation for 6 months on serum homocysteine levels and cognitive function in older people. This study was an experimental study of pre-post test design, carried out in Mampang subdistrict, South Jakarta. A total of 94 elderly people was recruited for this study, consisting of 44 females and 50 males. Serum homocysteine level was assessed by fluorescent polarization immunoassay and cognitive function by means of the mini mental state examination (MMSE before and after micronutrient supplementation. Mean serum homocysteine concentration after supplementation decreased significantly to 14.8 ± 5.8 mmol/L, compared with mean serum homocysteine level of 15.9 ± 5.9 mmol/L before supplementation (p=0.000. Multiple regression analysis indicated that the factors influencing post-supplementation MMSE scores were gender (â=-0.350; p=0.000, education (â=0.510; p=0.000 and post-supplementation homocysteine levels (â=-0.201; p=0.000, while age, pre-supplementation homocysteine levels and BMI did not affect MMSE scores. Homocysteine concentration decreased significantly after 6 months of supplementation. The factors affecting post-supplementation MMSE scores were gender, level of education, and post-supplementation homocysteine level.

    The aim of the present study was to investigate immunomodulatory effects of Agaricus bisporus, white bottom mushroom powder (WBMP) on common carp (Cyprinus carpio) fingerlings. Carps were fed on different levels of WBMP (0, 0.5, 1 and 2%) for 8 weeks and at the end of feeding trial, skin mucus immune parameters (total Ig, lysozyme and protease activity), cytokines gene expression (TNF-alpha, IL1b, IL8) in intestine as well as serum non-specific immune parameters (total Ig, lysozyme and ACH50) were measured. The results showed significant dose dependent increase of skin mucus immune parameters in carps fed WBMP (P  0.05). In case of serum non-specific immune parameters, except lysozyme activity, other parameters (Ig total and ACH50) were significantly affected by dietary inclusion of WBMP (P  0.05). Furthermore, feeding on WBMP supplemented diet significantly improved growth performance (P < 0.05). These results indicated that WBMP can be considered as a promising immunostimulants in early stage of common carp culture.

    The goal of the present study was to investigate the effects of lithium administration on behavior, oxidative stress parameters and cytokine levels in the periphery and brain of mice subjected to an animal model of mania induced by paradoxical sleep deprivation (PSD). Male C57 mice were treated with saline or lithium for 7 days. The sleep deprivation protocol started on the 5th day during for the last 36 hours of the treatment period. Immediately after the sleep deprivation protocol, animals locomotor activity was evaluated and serum and brain samples was extracted to evaluation of corticosterone and adrenocorticotropic hormone circulating levels, oxidative stress parameters and citokynes levels. The results showed that PSD induced hyperactivity in mice, which is considered a mania-like behavior. PSD increased lipid peroxidation and oxidative damage to DNA, as well as causing alterations to antioxidant enzymes in the frontal cortex, hippocampus and serum of mice. In addition, PSD increased the levels of cytokines in the brains of mice. Treatment with lithium prevented the mania-like behavior, oxidative damage and cytokine alterations induced by PSD. Improving our understanding of oxidative damage in biomolecules, antioxidant mechanisms and the inflammatory system - alterations presented in the animal models of mania - is important in helping us to improve our knowledge concerning the pathophysiology of BD, and the mechanisms of action employed by mood stabilizers. © 2017 John Wiley & Sons A/S.

    Diazinon is one of the organophosphate pesticides of wide spectrum insect-killing power. Diazinon extensive application as an effective pesticide was associated with direct or indirect modulation of major and vital immune mechanisms. This study addressed the effect of diazinon toxicity on cytokines that are involved in the regulation of innate, cellular and humoral immune responses. Mice intoxicated with 50 mg/kg (1/5 LD50) body weight for 30 days indicated gradual decrease in the level of interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-10 (IL-10), interleukin-12 (IL-12) and interferon-gamma (IFN-gamma) in the splenocytes cultures that were pulsed with phytohaemagglutinin (PHA). Sever suppression of these cytokines was confirmed by the RT-PCR. The level of IL-10 in CD4(+), CD8(+), and B cells indicated significant increase, whereas INF-gamma level was significantly decreased in B cells only. On the molecular level, the INF-gamma mRNA synthesis was significantly increased in all cells subpopulation, whereas, IL-2 mRNA synthesis was only increased in CD4(+). It was shown that diazinon immunotoxicity in mice capable of modulating the major cytokines involved in the regulation of the immune responses. In certain stage of diazinon toxicity, Th2 type responses appeared dominant. Diazinon could accelerate the INF- gamma and IL-2 mRNA synthesis but their translation might be impaired.

    Full Text Available There has been an increase in the number of individuals seeking testosterone (T replacement treatment (TRT due to a decrease in their blood T levels. Prostate cancer (PCa is also an important issue in the same age group. However, we, urologists, are anxious about PCa development after T treatment. This is because it has been assumed that T may cause PCa or exacerbate insidious PCa which is already present. In this paper, recent developments regarding the relationship between serum levels of sex hormone and prostate tissue, the causal relationship between T and development of PCa, the effect of TRT on the group of patients who are at high risk of developing PCa, the suitability of TRT for patients who have already been diagnosed with PCa, and the effect of TRT on serum prostate-specific antigen level are analyzed.

    Th17 cells have been associated with immune-mediated diseases in humans but it has still not been determined whether they play a role in immune thrombocytopenia. We evaluated representative cytokines of the Th17, Th1, Th2 and Treg cell commitment in the serum of patients with chronic immune thrombocytopenia, as well as the cell source of IL-17A. Higher levels of IL-17A and Th17-related cytokines, and an increased percentage of IL-17A producing CD4+ and neutrophils were observed in patients. The levels of cytokines involved in Th1 cell commitment IFN-γ, IL-2, IL12-p70 and the percentages of Th1 cells were also increased, but IL-4 was not detected. Although the concentrations of IL-10 were higher, the levels of TGF-β were similar in both groups. In conclusion, our results point to a putative role for Th-17 cells/IL-17A cytokine in the pathogenesis of chronic immune thrombocytopenia. PMID:21972211
