    Full Text Available OBJECTIVE: To test the usefulness of serum concentrations of tumor necrosis factor-like weak inducer of apoptosis (sTWEAK and soluble scavenger receptor CD163 (sCD163 as markers of subtle inflammation in patients with type 1 diabetes mellitus (T1DM without clinical cardiovascular (CV disease and to evaluate their relationship with arterial stiffness (AS. METHODS: Sixty-eight patients with T1DM and 68 age and sex-matched, healthy subjects were evaluated. Anthropometrical variables and CV risk factors were recorded. Serum concentrations of sTWEAK and sCD163 were measured. AS was assessed by aortic pulse wave velocity (aPWV. All statistical analyses were stratified by gender. RESULTS: T1DM patients showed lower serum concentrations of sTWEAK (Men: 1636.5 (1146.3-3754.8 pg/mL vs. 765.9 (650.4-1097.1 pg/mL; p<0.001. Women: 1401.0 (788.0-2422.2 pg/mL vs. 830.1 (562.6-1175.9 pg/mL; p = 0.011 compared with their respective controls. Additionally, T1DM men had higher serum concentrations of sCD163 (285.0 (247.7-357.1 ng/mL vs. 224.8 (193.3-296.5 ng/mL; p = 0.012 compared with their respective controls. sTWEAK correlated negatively with aPWV in men (r = -0.443; p<0.001. However, this association disappeared after adjusting for potential confounders. In men, the best multiple linear regression model showed that the independent predictors of sTWEAK were T1DM and WHR (R(2 = 0.640; p<0.001. In women, T1DM and SBP were the independent predictors for sTWEAK (R(2 = 0.231; p = 0.001. CONCLUSION: sTWEAK is decreased in T1DM patients compared with age and sex-matched healthy subjects after adjusting for classic CV risk factors, although sTWEAK levels may be partially influenced by some of them. Additionally, T1DM men have higher serum concentrations of sCD163. These results point out an association between the inflammatory system and CV risk in T1DM.

    Full Text Available BACKGROUND: The diagnosis of sepsis is challenging and there is an unmet need for sensitive and specific diagnostic and prognostic biomarkers. Following activation of macrophages and monocytes, the haptoglobin-haemoglobin receptor (CD163 and the mannose receptor (MR are shed into the circulation (sCD163 and sMR. OBJECTIVE: We investigated monocyte expression of CD163 and MR, and levels of sCD163 and sMR in septic and non-septic patients, and in healthy controls. We hypothesised that these receptors are elevated during sepsis and can be used diagnostic and prognostic. METHODS: Twenty-one patients with severe sepsis or septic shock and 15 critically ill non-septic patients were included in this prospective observational study at three ICUs at Aarhus University Hospital and Randers Regional Hospital, Denmark. Fifteen age- and gender-matched healthy volunteers served as controls. Levels of sCD163 and sMR were measured using a sandwich ELISA and monocyte expression of CD163 and MR was evaluated by flow cytometry during the first four days of ICU stay. The diagnostic and prognostic values of the receptors were assessed using AUROC curves. RESULTS: At ICU admission and during the observation period, monocyte expression of CD163 and levels of sCD163 and sMR were significantly higher in septic patients compared with non-septic patients and healthy controls (p<0.01 for all comparisons. Monocytes did not express MR. The diagnostic values estimated by AUROC were 1.00 for sMR, 0.95 for sCD163, 0.87 for CRP, and 0.75 for monocyte-bound CD163. Among the septic patients, monocyte expression of CD163 was higher in non-survivors compared with survivors at ICU admission (p = 0.02 and during the observation period (p = 0.006. The prognostic value of monocyte-bound CD163 estimated by AUROC at ICU admission was 0.82. CONCLUSION: The macrophage-specific markers CD163, sCD163, and sMR are increased in septic patients. Particularly sMR is a promising new

    Caroline Lin Lin Chua

    Full Text Available In Plasmodium falciparum malaria, activation of monocytes and macrophages (monocytes/macrophages can result in the production of various inflammatory mediators that contribute to immunopathology. Soluble CD163 (sCD163 is a specific marker of monocyte/macrophage activation typically found at increased levels during various inflammatory conditions and can be associated with poor clinical outcomes. To better understand the relationships between levels of sCD163 and clinical parameters in women with placental malaria, we measured plasma sCD163 levels in maternal peripheral and placental blood compartments at delivery and determined their correlations with birth weight and maternal haemoglobin concentrations. sCD163 levels were negatively correlated with birth weight only in the placental compartment (r = -0.145, p = 0.03 and were inversely correlated with maternal haemoglobin concentrations, both in peripheral blood (r = -0.238, p = 0.0004 and in placental blood (r = -0.259, p = 0.0001. These inverse relationships suggest a potential role for monocyte/macrophage activation in the pathogenesis of malaria in pregnancy, particularly in relation to malaria-associated anaemia.

    Full Text Available Abstract Background Sepsis is a common syndrome in critically ill patients and easily leads to the occurrence of acute kidney injury (AKI, with high mortality rates. This study aimed to investigate the diagnostic value of urine soluble CD163 (sCD163 for identification of sepsis, severity of sepsis, and for secondary AKI, and to assess the patients’ prognosis. Methods We enrolled 20 cases with systemic inflammatory response syndrome (SIRS, 40 cases with sepsis (further divided into 17 sepsis cases and 23 severe sepsis cases admitted to the intensive care unit (ICU, and 20 control cases. Results for urine sCD163 were recorded on the day of admission to the ICU, and AKI occurrence was noted. Results On the day of ICU admission, the sepsis group exhibited higher levels of urine sCD163 (74.8 ng/ml; range: 47.9-148.3 ng/ml compared with those in the SIRS group (31.9 ng/ml; 16.8-48.0, P . The area under the curve (AUC was 0.83 (95% confidence interval [CI]: 0.72-0.94, P  the sensitivity was 0.83, and the specificity was 0.75 (based on a cut-off point of 43.0 ng/ml. Moreover, the severe sepsis group appeared to have a higher level of sCD163 compared with that in the sepsis group (76.2; 47.2-167.5 ng/ml vs. 74.2; 46.2-131.6 ng/ml, but this was not significant. For 15 patients with AKI, urine sCD163 levels at AKI diagnosis were significantly higher than those of the remaining 35 sepsis patients upon ICU admission (121.0; 74.6-299.1 ng/ml vs. 61.8; 42.8-128.3 ng/ml, P = 0.049. The AUC for urine sCD163 was 0.688 (95% CI: 0.51-0.87, P = 0.049. Sepsis patients with a poor prognosis showed a higher urine sCD163 level at ICU admission (98.6; 50.3-275.6 ng/ml vs. 68.0; 44.8-114.5 ng/ml, but this was not significant. Patients with AKI with a poor prognosis had higher sCD163 levels than those in patients with a better prognosis (205.9; 38.6-766.0 ng/ml vs. 80.9; 74.9-141.0 ng/ml, but this was not significant.

    Full Text Available OBJECTIVE: We investigated serum soluble CD163 (sCD163 levels for use in the diagnosis, severity assessment, and prognosis of sepsis in the critical ill patients and compared sCD163 with other infection-related variables. METHODS: During july 2010 and April 2011, serum was obtained from 102 sepsis patients (days 1, 3, 5, 7, and 10 after admission to an ICU and 30 systemic inflammatory response syndrome (SIRS patients with no sepsis diagnosed. Serum levels of sCD163, procalcitonon (PCT, and C reactive protein (CRP were determined respectively. Sequential organ failure assessment (SOFA scores for sepsis patients were also recorded. Then evaluated their roles in sepsis. RESULTS: The sCD163 levels were 0.88(0.78-1.00 ug/mL for SIRS patients, 1.50(0.92-2.00 ug/mL for moderate sepsis patients, and 2.95(2.18-5.57 ug/mL for severe sepsis patients on day 1. The areas under the ROC curves for sCD163, CRP, and PCT for the diagnosis of sepsis were, respectively, 0.856(95%CI: 0.791-0.921, 0.696(95%CI: 0.595-0.797, and 0.629(95%CI: 0.495-0.763, At the recommended cut-off 1.49 ug/mL for sCD163, the sensitivity is 74.0% with 93.3% specificity. Based on 28-day survivals, sCD163 levels in the surviving group stay constant, while they tended to gradually increase in the non-surviving group.The area under the ROC curve for sCD163 for sepsis prognosis was 0.706(95%CI 0.558-0.804. Levels of sCD163 with cut-off point >2.84 ug/mL have sensitivity of 55.8.0%, specificity 80.4%. Common risk factors for death and sCD163 were included in multivariate logistic regression analysis; the odds ratios (OR for sCD163 and SOFA scores for sepsis prognosis were 1.173 and 1.396, respectively (P<0.05. Spearman rank correlation analysis showed that sCD163 was weakly, but positively correlated with CRP, PCT, and SOFA scores (0.2< r <0.4, P<0.0001, but not with leukocyte counts (r <0.2, P = 0.450.

    Full Text Available BACKGROUND: Soluble CD163 (sCD163 is a macrophage specific protein known to be up-regulated in serum from patients with multiple sclerosis (MS. OBJECTIVE: To investigate sCD163 in serum and CSF (cerebrospinal fluid from patients undergoing MS diagnostic work-up and analyse its potential as a diagnostic biomarker. METHODS: After a full MS diagnostic work-up, including collection of paired samples of CSF and serum, 183 patients were evaluated for inclusion in this study. Patients were divided into groups based on their diagnosis. Patients with normal clinical and paraclinical findings were grouped as symptomatic controls. Serum and CSF levels of sCD163 were determined by enzyme-linked immunosorbent assay (ELISA. RESULTS: sCD163 could be measured in all serum and CSF samples. A high sCD163 CSF/serum ratio in relation to molecular weight was found, strongly indicating local production in the CNS. Median levels of sCD163 were significantly decreased in serum and significantly elevated in CSF in patients with relapsing-remitting, and primary-progressive MS. There were, however, some overlaps of the measures between groups. In a receiver operating characteristic (ROC analysis sCD163 CSF/serum ratio had an area under the curve of 0.72. CONCLUSION: The sCD163 CSF/serum ratio was significantly increased in patients with MS and may reflect macrophage activation in MS lesions. These results suggest that primary progressive MS also is driven by inflammation in which the innate immune system plays a pivotal role.

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. PMID:26209500

    Full Text Available PURPOSE: We investigated whether serum interleukin (IL-8 reflects the tumor microenvironment and has prognostic value in patients with oral squamous cell carcinoma (OSCC. EXPERIMENTAL DESIGN: Fifty OSCC patients who received radical resection of their tumor(s were enrolled. Preoperative sera were measured for IL-8 by ELISA. Expression of IL-8 and the infiltration of immune cells in tumor tissues were analyzed by an immunohistochemical staining of surgical specimens. RESULTS: We found that disease-free survival (DFS was significantly longer in the Stage I/II OSCC patients with low serum IL-8 levels compared to those with high levels (p = 0.001. The tumor expression of IL-8, i.e., IL-8(T and the density of CD163-positive cells in the tumor invasive front, i.e., CD163(IF were correlated with the serum IL-8 level (p = 0.033 and p = 0.038, respectively, and they were associated with poor clinical outcome (p = 0.007 and p = 0.002, respectively, in DFS in all patients. A multivariate analysis revealed that N status, IL-8(T and CD163(IF significantly affected the DFS of the patients. Further analysis suggested that combination of N status with serum IL-8, IL-8(T or CD163(IF may be a new criterion for discriminating between OSCC patients at high and low risk for tumor relapse. Interestingly, the in vitro experiments demonstrated that IL-8 enhanced generation of CD163-positive M2 macrophages from peripheral blood monocytes, and that the cells produced IL-10. CONCLUSIONS: These findings indicate that IL-8 may be involved in poor clinical outcomes via generation of CD163-positive M2 macrophages, and that these factors in addition to N status may have prognostic value in patients with resectable OSCSS.

  16. Differential expression of CD163 on monocyte subsets in healthy and HIV-1 infected individuals.

    Emma Tippett

    Full Text Available CD163, a haptoglobin-hemoglobin (Hp-Hb scavenger receptor, expressed by monocytes and macrophages, is important in resolution of inflammation. Age-related non-AIDS co-morbidities in HIV-infected individuals, particularly dementia and cardiovascular disease, result in part from effects of HIV-1 infection on monocyte and macrophage biology. CD163 co-expression on CD14+CD16++ monocytes has been proposed as a useful biomarker for HIV-1 disease progression and the presence of HIV associated dementia. Here we investigated CD163 expression on monocyte subsets ex vivo, on cultured macrophages, and soluble in plasma, in the setting of HIV-1 infection. Whole blood immunophenotyping revealed CD163 expression on CD14++CD16- monocytes but not on CD14+CD16++ monocytes (P = 0.004, supported by CD163 mRNA levels. Incubation with M-CSF induced CD163 protein expression on CD14+CD16++ monocytes to the same extent as CD14++CD16- monocytes. CD163 expression on CD14++CD16+ monocytes from HIV-infected subjects was significantly higher than from uninfected individuals, with a trend towards increased expression on CD14++CD16- monocytes (P = 0.019 and 0.069 respectively, which is accounted for by HIV-1 therapy including protease inhibitors. Shedding of CD163 was shown to predominantly occur from the CD14++CD16- subset after Ficoll isolation and LPS stimulation. Soluble CD163 concentration in plasma from HIV-1 infected donors was similar to HIV-1 uninfected donors. Monocyte CD163 expression in HIV-1 infected patients showed a complicated relationship with classical measures of disease progression. Our findings clarify technical issues regarding CD163 expression on monocyte subsets and further elucidates its role in HIV-associated inflammation by demonstrating that CD163 is readily lost from CD14++CD16- monocytes and induced in pro-inflammatory CD14+CD16++ monocytes by M-CSF. Our data show that all monocyte subsets are potentially capable of differentiating into CD

    Full Text Available Recently soluble CD163 (sCD163, a cleaved form of the macrophage receptor CD163, was identified as a macrophage-specific risk-predictor for developing Type 2 Diabetes. Here, we investigate circulating levels of sCD163 in gestational diabetes mellitus (GDM. Furthermore, given the role of the placenta in the pathogenesis of GDM, we assessed placental contribution to sCD163 secretion. Paired maternal (venous and umbilical vein blood samples from GDM (n = 18 and Body Mass Index (BMI matched control women (n = 20 delivered by caesarean section at 39-40 week gestation were assessed for circulating levels of sCD163, Tumour necrosis factor alpha (TNF-α and Interleukin 6 (IL-6. Media from explant culture of maternal subcutaneous fat and corresponding placental tissues were assayed for these same molecules. CD163 positive cell numbers were determined in placental and adipose tissues of GDM and control women. We found significantly elevated circulating sCD163 levels in GDM mothers (688.4±46.9 ng/ml vs. 505.6±38.6 ng/ml and their offspring (418.2±26.6 ng/ml vs. 336.3±24.4 ng/ml [p<0.05 for both] as compared to controls, together with elevated circulating TNF-α and IL-6 levels. Moreover, both GDM placentae (268.1±10.8 ng/ml/mg vs. 187.6±20.6 ng/ml/mg and adipose explants (41.1±2.7 ng/ml/mg vs. 26.6±2.4 ng/ml/mg released significantly more sCD163 than controls. Lastly, significantly more CD163 positive cells were observed in GDM placentae (25.7±1.1 vs. 22.1±1.2 and adipose tissue (19.1±1.1 vs 12.7±0.9 compared to controls. We describe elevated sCD163 levels in GDM and identify human placenta as a novel source of sCD163 suggesting that placental tissues might contribute to the increased levels of circulating sCD163 in GDM pregnancies.

    Visceral fat differs from subcutaneous fat by higher local inflammation and increased release of IL-6 and free fatty acids (FFA) which contribute to hepatic steatosis. IL-6 has been shown to upregulate the monocyte/macrophage specific receptor CD163 whose soluble form, sCD163, is increased in inflammatory diseases. Here, it was analyzed whether CD163 and sCD163 are differentially expressed in the human fat depots and fatty liver. CD163 mRNA and protein were similarly expressed in paired samples of human visceral and subcutaneous fat, and comparable levels in portal venous and systemic venous blood of liver-healthy controls indicate that release of sCD163 from visceral adipose tissue was not increased. CD163 was also similarly expressed in steatotic liver when compared to non-steatotic tissues and sCD163 was almost equal in the respective sera. Concentrations of sCD163 were not affected when passing the liver excluding substantial hepatic removal/release of this protein. A high concentration of IL-6 upregulated CD163 protein while physiological doses had no effect. However, sCD163 was not increased by any of the IL-6 doses tested. FFA even modestly decreased CD163 and sCD163. The anti-inflammatory mediators fenofibrate, pioglitazone, and eicosapentaenoic acid (EPA) did not influence sCD163 levels while CD163 was reduced by EPA. These data suggest that in humans neither visceral fat nor fatty liver are major sources of sCD163. PMID:21839737

    The course of disease among HIV-2, HIV-1, and HIV-1/2 dually infected patients is different. We investigated the macrophage activation marker soluble CD163 (sCD163) dynamics in 212 HIV-1, HIV-2, and HIV-1/2 dually infected patients. There were no differences in sCD163 levels at baseline or during follow-up without antiretroviral therapy (ART). At follow-up on ART, median sCD163 levels were decreased for HIV-1-infected patients (P < 0.001), but not among HIV-2 (P = 0.093) or HIV-1/2 dually infected patients (P = 0.145). The larger decrease in sCD163 levels among HIV-1-infected patients during ART may indicate an HIV type-dependent differential effect of ART on macrophage activation during HIV infection.

    Lysis of RBCs during numerous clinical settings such as severe hemolytic anemia, infection, tissue injury, or blood transfusion releases the endogenous damage-associated molecular pattern, hemoglobin (Hb), into the plasma. The redox-reactive Hb generates cytotoxic reactive oxygen species, disrupting the redox balance and impairing the immune-responsive blood cells. Therefore, it is crucial to understand how the immune system defends against the cytotoxic Hb. We identified a shortcut "capture and quench" mechanism of detoxification of Hb by the monocyte scavenger receptor CD163, independent of the well-known dominant antioxidant, haptoglobin. Our findings support a highly efficient two-pass mechanism of detoxification and clearance of Hb: 1) a direct suppression of Hb-pseudoperoxidase activity by CD163, involving an autocrine loop of CD163 shedding, sequestration of Hb, recycling, and homeostasis of CD163 in human monocytes and 2) paracrine transactivation of endothelial cells by the shedded soluble CD163 (sCD163), which further detoxifies and clears residual Hb. We showed that sCD163 and IgG interact with free Hb in the plasma and subsequently the sCD163-Hb-IgG complex is endocytosed into monocytes via FcγR. The endocytosed sCD163 is recycled to restore the homeostasis of CD163 on the monocyte membrane in an autocrine cycle, whereas the internalized Hb is catabolized. Using ex vivo coculture experiments, we demonstrated that the monocyte-derived sCD163 and IgG shuttle residual plasma Hb into the proximal endothelial cells. These findings suggest that CD163 and IgG collaborate to engage monocytes and endothelial cells in a two-pass detoxification mechanism to mount a systemic defense against Hb-induced oxidative stress.

    The hemoglobin scavenger receptor CD163 is exclusively expressed in the monocytic lineage and preferentially in tissue resident macrophages of the M2 phenotype and in macrophages in sites of inflammation and tumor growth. In the present study we have designed liposomes specifically targeting CD163...... by hydrophobic linkage of CD163-binding monoclonal antibodies to polyethylene glycol-coated liposomes ('stealth liposomes'). Targeting to the endocytic CD163 protein greatly increased the uptake of liposomes in CD163 transfected cells and macrophages as visualized by confocal microscopy and flow...... cytometry of cells exposed to CD163 targeting liposomes loaded with calcein. Strong cytotoxic effects were seen in CD163-expressing human monocytes by using the chemotherapeutic agent doxorubicin as cargo of the liposomes.

    Delayed cerebral ischemia resulting from extracellular hemoglobin is an important determinant of outcome in subarachnoid hemorrhage. Hemoglobin is scavenged by the CD163-haptoglobin system in the circulation, but little is known about this scavenging pathway in the human CNS. The components of this system were analyzed in normal cerebrospinal fluid and after subarachnoid hemorrhage. The intrathecal presence of the CD163-haptoglobin–hemoglobin scavenging system was unequivocally demonstrated. ...

    proteins of original virus and virus grown for 5 passages on PK15Sn-CD163 cells showed either no amino acid (aa changes (VR-2332 and 07V063, one aa (LV, two aa (08V194 or three aa (08V204 changes. None of these changes are situated in known neutralizing epitopes. Conclusions A PRRSV susceptible cell line was constructed that can grow virus to similar levels compared to currently available cell lines. Mutations induced by growth on this cell lines were either absent or minimal and located outside known neutralizing epitopes. Together, the results show that this cell line can be used to produce vaccine virus and for PRRSV virus isolation.

    Full Text Available Abstract Background Epithelial ovarian cancer is one of the leading causes of gynaecological cancer morbidity and mortality in women. Early stage ovarian cancer is usually asymptomatic, therefore, is often first diagnosed when it is widely disseminated. Currently available diagnostics lack the requisite sensitivity and specificity to be implemented as community-based screening tests. The identification of additional biomarkers may improve the diagnostic efficiency of multivariate index assays. The aims of this study were to characterise and compare the ovarian tissue immunohistochemical localisation and plasma concentrations of three putative ovarian cancer biomarkers: human cationic antimicrobial protein-18 (hCAP-18; lactoferrin; and CD163 in normal healthy women and women with ovarian cancer. Methods In this case–control cohort study, ovarian tissue and blood samples were obtained from 164 women (73 controls, including 28 women with benign pelvic masses; 91 cancer, including 21 women with borderline tumours. Localisation of each antigen within the ovary was assessed by immunohistochemistry and serum concentrations determined by ELISA assays. Results Immunoreactive (ir hCAP-18 and lactoferrin were identified in epithelial cells, while CD163 was predominately localised in stromal cells. Tissue ir CD163 increased significantly (PP Conclusions The data obtained in this study establishes the localisation and concentrations of CD163, hCAP-18, and lactoferrin in ovarian tumours and peripheral blood. Individually, the 3 biomarkers display only modest diagnostic efficiency as assessed by AUC. When combined in a multivariate index assay, however, diagnostic efficiency increases significantly. As such, the utility of the biomarker panel, as an aid in the diagnosis of cancer in symptomatic women, is worthy of further investigation in a larger phase 2 biomarker trial.

    2010-06-01

    Full Text Available Abstract Background The scavenger receptor cysteine rich (SRCR domain is an ancient and conserved protein domain. CD163 and WC1 molecules are classed together as group B SRCR superfamily members, along with Spα, CD5 and CD6, all of which are expressed by immune system cells. There are three known types of CD163 molecules in mammals, CD163A (M130, coded for by CD163, CD163b (M160, coded for by CD163L1 and CD163c-α (CD163L1 or SCART, while their nearest relative, WC1, is encoded by a multigene family so far identified in the artiodactyl species of cattle, sheep, and pigs. Results We annotated the bovine genome and identified genes coding for bovine CD163A and CD163c-α but found no evidence for CD163b. Bovine CD163A is widely expressed in immune cells, whereas CD163c-α transcripts are enriched in the WC1+ γδ T cell population. Phylogenetic analyses of the CD163 family genes and WC1 showed that CD163c-α is most closely related to WC1 and that chicken and platypus have WC1 orthologous genes, previously classified as among their CD163 genes. Conclusion Since it has been shown that WC1 plays an important role in the regulation of γδ T cell responses in cattle, which, like chickens, have a high percentage of γδ T cells in their peripheral blood, CD163c-α may play a similar role, especially in species lacking WC1 genes. Our results suggest that gene duplications resulted in the expansion of CD163c-α-like and WC1-like molecules. This expanded repertoire was retained by species known as "γδ T cell high", but homologous SRCR molecules were maintained by all mammals.

    CD163 and sialoadhesin (SN) were reported as two essential receptors for the porcine reproductive and respiratory syndrome virus. To investigate the relationship between these two genes and porcine immunity, we assigned porcine CD163 and SN respectively to SSC5q21-q24 and SSC17q23 by IMpRH. Expression profiles revealed that CD163 and SN were ubiquitously expressed in ten tissues, and were expressed highly in lymph gland, spleen and liver, which implied the potential functions of CD163 and SN in immunity. Moreover, a single nucleotide polymorphism (SNP) c.3534C>T was found in 3'-UTR of the CD163 gene and association analysis showed that this gene was significantly associated with the IgG content in blood (P G located in exon4 of the SN gene which caused the amino acid transition from histidine to arginine was detected, and it was significantly associated with the WBC count in the peripheral blood (P < 0.05). These results provided fundamental evidence for CD163 and SN as two functional candidate genes affecting immunity in pigs. PMID:21786159

    The cell population of peripheral blood monocytes/macrophages (MO) is heterogeneous: The majority of the MO are CD14++ CD16- and named "classical" (= MO1). Furthermore, two other subpopulations were described: CD14++ CD16+ ("intermediate" = MO2) and CD14+ CD16++ ("non-classical" = MO3). It is reported that MO2 possess anti-inflammatory properties and express the MO lineage marker CD163. On a hydrophilic neutrally charged acrylamide-based hydrogel human intermediate (CD14++ CD16+ ), angiogenically stimulated CD163++ monocytes/macrophages (aMO2) maintained a proangiogenic and noninflammatory status for at least 14 days. Here, we explored whether this aMO2 subset adhered to hydrophobic poly(n-butyl acrylate) networks (cPnBA) and also remained in its proangiogenic and noninflammatory status. Because substrate elasticity can impact adherence, morphology, and function of cells, cPnBAs with different Young's modulus (250 and 1100 kPa) were investigated, whereby their elasticity was tailored by variation of the cross-linker content and matched to the elasticity of human arteries. The cPnBAs exhibited similar surface properties (e.g., surface roughness), which were maintained after ethylene oxide sterilization and exposure in serum-free cell culture medium for 18 h at 37°C. aMO2 were seeded on cPnBA samples (1.7 × 10(5) cells/1.33 cm(2) ) in Dulbecco's modified Eagle medium (DMEM high glucose) supplemented with vascular endothelial growth factor 165 (VEGF-A(165) , 10 ng/mL) and fetal calf serum (10 vol%) for 3 and 72 h. On both polymeric samples (n = 3 each), the numbers of adherent cells per unit area were significantly higher (P < 0.01; cPnBA0250: 3 h 13 ± 5 cells/mm(2) , 72 h 234 ± 106 cells/mm(2) ; cPnBA1100: 3 h 14 ± 3 cells/mm(2) , 72 h 198 ± 113 cells/mm(2) ) compared to control cultures (glass, 3 h: 6 ± 3 cells/mm(2) , 72 h: 130 ± 83 cells/mm(2) ) and showed a typically spread morphology.

    Expression of the macrophage antigen CD163 in breast cancer cells is recently shown to be related to early distant recurrence and shortened survival. In this study, 163 patients with rectal cancer, included in the Swedish rectal cancer trial and followed up for a median of 71 months, were examined for the expression of CD163 in the primary tumors. The cancer cells expressed CD163 in the primary tumors in 23% (n = 32) of the patients. In pretreatment biopsies from 101 patients, 10 had CD163-positive cancers and these patients had earlier local recurrence (p CD163-negative tumors. When studying surgical specimens from 61 patients randomized to preoperative irradiation (5 x 5 Gy delivered in 1 week), it was found that 31% were CD163 positive whereas the corresponding figure was only 17% for 78 patients who were nonirradiated (p CD163-positive tumors there was a reduced apoptotic activity as measured with the Termina deoxynucleotidyl Transferase Biotin-dUTP Nick End Labeling (TUNEL) technique (p = 0.018). There tended also to be an increased proliferation activity measured as an expression of Ki-67 non significant (NS). It is concluded that primary rectal cancers may express CD-163, and this phenotypic macrophage trait is related to early local recurrence, shorter survival time and reduced apoptosis. Furthermore, the expression of CD163 is more common after irradiation. PMID:19582880

    Full Text Available Tumor-associated macrophages (TAMs play an important role in the progression and prognostication of numerous cancers. However, the role and clinical significance of TAM markers in oral squamous cell carcinoma (OSCC has not been elucidated. The present study was designed to investigate the correlation between the expression of TAM markers and pathological features in OSCC by tissue microarray. Tissue microarrays containing 16 normal oral mucosa, 6 oral epithelial dysplasia, and 43 OSCC specimens were studied by immunohistochemistry. We observed that the protein expression of the TAM markers CD68 and CD163 as well as the cancer stem cell (CSC markers ALDH1, CD44, and SOX2 increased successively from the normal oral mucosa to OSCC. The expressions of CD68 and CD163 were significantly associated with lymph node status, and SOX2 was significantly correlated with pathological grade and lymph node status, whereas ALDH1 was correlated with tumor stage. Furthermore, CD68 was significantly correlated with CD163, SOX2, and ALDH1 (P<0.05. Kaplan-Meier analysis revealed that OSCC patients overexpressing CD163 had significantly worse overall survival (P<0.05. TAM markers are associated with cancer stem cell marker and OSCC overall survival, suggesting their potential prognostic value in OSCC.

    Macrophages play an important role in rhabdomyolysis-acute kidney injury (AKI), although the molecular mechanisms involved in macrophage differentiation are poorly understood. We analyzed the expression and regulation of CD163, a membrane receptor mainly expressed by anti-inflammatory M2 macrophages, in rhabdomyolysis-AKI and developed targeted probes for its specific detection in vivo by MRI. Intramuscular injection of glycerol in mice promoted an early inflammatory response, with elevated proportion of M1 macrophages, and partial differentiation towards a M2 phenotype in later stages, where increased CD163 expression was observed. Immunohistological studies confirmed the presence of CD163-macrophages in human rhabdomyolysis-AKI. In cultured macrophages, myoglobin upregulated CD163 expression via HO-1/IL-10 axis. Moreover, we developed gold-coated iron oxide nanoparticles vectorized with an anti-CD163 antibody that specifically targeted CD163 in kidneys from glycerol-injected mice, as determined by MRI studies, and confirmed by electron microscopy and immunological analysis. Our findings are the first to demonstrate that CD163 is present in both human and experimental rhabdomyolysis-induced AKI, suggesting an important role of this molecule in this pathological condition. Therefore, the use of probes targeting CD163-macrophages by MRI may provide important information about the cellular composition of renal lesion in rhabdomyolysis. PMID:27162559

    Serum neopterin levels have been determined by RIA in 105 patients affected by chronic alcoholic liver disease, 68 of them cirrhotics, and in 12 controls. Serum Neopterin was significantly higher in patients than in controls, correlated with Pughs' score and Child's classification, and also with serum laminin and type III collagen N-terminal propeptide, and with histomorphometrically determined liver fibrosis. Serum neopterin levels were higher in patients who died than in survivors, serum neopterin levels over 19.15 nmol/l being associated with higher mortality rates. PMID:8261879

    Several routes of porcine reproductive and respiratory virus PRRSV transmission across the porcine diffuse epitheliochorial placentation have been proposed, but none have been proven. The objectives of this study were to investigate associations between numbers of CD163 and CD169 positive macrophages, cathepsin positive areolae, and type 2 PRRSV load at the maternal-fetal interface in order to examine important factors related to transplacental infection. On gestation day 85 ± 1, naïve pregnant gilts were inoculated with PRRSV (n = 114) or were sham inoculated (n = 19). At 21 days post-inoculation (dpi), dams and their litters were humanely euthanized and necropsied. Samples of the maternal-fetal interface (uterus with fully attached placenta) and fetal thymus were collected for analysis by RT-qPCR to quantify PRRSV RNA concentration. The corresponding paraffin-embedded uterine tissue sections were subjected to immunohistochemistry for PRRSV nucleocapsid N protein, CD163, CD169, and cathepsin. Our findings confirm significant increases in the numbers of PRRSV, CD163 and CD169 positive cells at the maternal-fetal interface during type 2 PRRSV infection in pregnant gilts. PRRSV load in fetal thymus was positively related to CD163(+) cell count in endometrium and negatively related to CD163(+) cell count in placenta, but unrelated to CD169 counts or cathepsin positive areolae. The endometrium:placenta ratio of CD163 cells, and to a lesser extent CD169 cells, was significantly associated with an increase fetal viral load in thymus. These findings suggest a more important role for CD163(+) cells following trans-placental PRRSV infection, but dichotomous responses in endometrium and placenta for both CD163 and CD169 cells.

    Full Text Available Objective. To evaluate the expression of CD64 and CD163 on neutrophils and monocytes in SIRS with/without sepsis and to compare the diagnostic accuracy of CD64 and CD163 molecules expression determined as (1 mean fluorescence intensities (MFI of CD64 and CD163; and (2 the ratio (index of linearized MFI to the fluorescence signal of standardized beads. Patients and methods. Fifty-six critically ill neonates and children with systemic inflammatory response syndrome (SIRS and suspected sepsis, classified into two groups: SIRS with sepsis (n=29 and SIRS without sepsis (n=27. Results. CD64 and CD163 MFI measured on neutrophils and monocytes were elevated in patients with SIRS with sepsis. Diagnostic accuracy of indexes was equal to diagnostic accuracy of MFI for CD64 on neutrophils (0.833 versus 0.854 for day 0 and 0.975 versus 0.983 for day 1 and monocytes (0.811 versus 0.865 for day 0 and 0.825 versus 0.858 for day 1, and CD163 on neutrophils (0.595 versus 0.655 for day 0 and 0.677 versus 0.750 for day 1, but not for CD163 on monocytes. Conclusion. CD64 MFI, CD163 MFI, CD64 indexes for neutrophils and monocytes, and CD163 index for neutrophils can all be used for discrimination of SIRS and sepsis in critically ill neonates and children. CD64 index for neutrophils, however, is superior to all other markers.

    International Nuclear Information System (INIS)

    The results of the serum levels of adiponectin in pre eclamptic patients are conflicting. Objective: The aim of the present study was to assess serum levels of adiponectin in women with pre eclampsia compared with healthy pregnant women. Methods: A cross-sectional study was designed. The case group consisted of women with pre eclampsia (n=30). The control group consisted of 30 matched normal pregnant women. Serum levels of adiponectin were assessed using enzyme-linked immunosorbent assay method. Results: Serum levels of adiponectin were significantly higher in the pre eclamptic group than those in the normal control group. In the pre eclamptic patients serum levels of adiponectin showed a significant negative correlation with body mass index while no correlation was found in the normal pregnant women. In women with pre eclampsia, levels of adiponectin were decreased significantly in the overweight women compared with normal weight women, while in the control group no significant difference was observed. Conclusion: In conclusion, elevation of adiponectin levels might be a physiological feedback response to minimize endothelial dysfunction in pre eclamptic patients. (author)

    Serum zinc level amongst children with protein energy malnutrition (PEM) was evaluated in a control study conducted in the Department of Paediatrics, Allama Iqbal Medical College and Jinnah Hospital, Lahore. Twenty-five children with PEM and 25 healthy children as control from the community were screened. Mean serum zinc level was found to be 54.48 -+ 18.91 mg/dl in children with PEM while it was 72.72 -+ 8.21 mg/dl in control group (P < 0.001). No significant difference in zinc level was noted between both sexes in each group. Marasmic 16 children revealed mean serum zinc level of 57.55 -+ 18.16 mg/dl while in Kwashiorkor it was 44.57 -+ 13.66 mg/dl. Serum zinc was significantly low in Kwashiorkor than in marasmus (P < 0.001). It was also significantly low in children with acute or chronic diarrhea associated with malnutrition (44.66 -+ 16.0 mg/dl). Acute respiratory infections in these children were not associated with low serum zinc level (71.66 -+ 16.51 mg/dl). (author)

    A radioimmunoassay (RIA) method for erythropoietin (Epo) was developed and validated against the polycythaemic mouse assay. The correlation was good, with a r=0.94. Several other criteria of specificity were also filled by the RIA, which had a lower detection limit of 5 mU/ml. The mean serum-Epo level in 6 patients with secondary polycythaemia, 50.2 +- 26.2 mU/ml, was significantly higher than in a group of 11 normal subjects, 28.7 +- 7.2 mU/ml (P<0.0002). However, the Epo level in 31 polycythaemia vera (PV) patients, M = 21.9 +- 6.6 mU/ml, was not significantly different from normal (P = 0.006). Since previous studies with bioassay of heat-treated and concentrated plasma samples have shown a decreased serum-Epo level in PV, Epo levels were measured before and after heat treatment and concentration of samples from normals and polycythaemics. It was found that the levels of immunoreactive material increased after heat treatment and 40 times concentration in samples from normals and patients with secondary polycythaemias, but decreased in PV. We conclude that the Epo levels in serum in the low range measured by our and previous RIA:s probably are not true Epo levels but are partly due to an unspecific serum effect, that was removed by heat treatment.

    The sequencing of the bovine genome and development of mass spectrometry, in conjunction with flow cytometry (FC), have afforded an opportunity to complete the characterization of the specificity of monoclonal antibodies (mAbs), only partially characterized during previous international workshops focused on antibody development for livestock (1991, Leukocyte Antigens in Cattle, Sheep, and Goats; 1993, Leukocyte Antigens of Cattle and Sheep; 1996, Third Workshop on Ruminant Leukocyte Antigens). The objective of this study was to complete the characterization of twelve mAbs incompletely characterized during the workshops that reacted with molecules predominantly expressed on bovine monocytes and use them to provide further information on the phenotypic complexity of monocyte subsets in ruminants. Analysis revealed that the mAbs could be grouped into three clusters that recognize three different molecules: CD11c, CD14, and CD163. Following characterization, comparison of the patterns of expression of CD14 and CD163 with expression of CD16, CD172a, and CD209 revealed the mononuclear cell population is comprised of multiple subsets with differential expression of these molecules. Further analysis revealed the epitopes recognized by mAbs to CD14 and CD163 are conserved on orthologues in sheep and goats. In contrast to CD14 that is also expressed on sheep and goat granulocytes, CD163 is a definitive marker for their monocytes. PMID:27496743

    2015-01-01

    Full Text Available Introduction: Olanzapine is a commonly used antipsychotic. Prolactin elevation is a common adverse effect of anstipsychotics, and serum prolactin elevation is seen in about 30% patients treated with olanzapine. There are confounding results about dose dependency of olanzapine and prolactin elevation, and also the duration of treatment. Method: Fifty six patients, 36 male and 20 female, who were taking olanzapine for any condition for more than a month at a constant dose were enrolled in the study. Patients’ age, weight, body mass index (BMI, serum prolactin levels, and some biochemical values were recorded. Patients were taken from the review outpatient department (OPD after due consent. Results: Five each in male and female groups showed elevation of serum prolactin (estimated to be high if >20 ng/dl for males, and >25 ng/dl for females. In females, the elevation was found at lesser dose of olanzapine (13 mg/day, in males 18 mg/day and early in the treatment (2.4 months vs. 9.7 months in males. Males tended to show raised prolactin with higher doses of olanzapine (mean 18 mg/day. Females (26.31% also showed higher prevalence of prolactin elevation compared to males (13.51%. No other parameter was found to modify the prolactin levels. Conclusion: Olanzapine causes elevation of serum prolactin, though lesser degree than some other antipsychotics. Females are more prone to have raised serum prolactin with olanzapine compared to males. However, the elevation seems to be transient. Higher doses of olanzapine tend to cause elevation of serum prolactin. Serum prolactin estimation in patients taking olanzapine may be undertaken to maintain quality life, particularly in females.

    Full Text Available BACKGROUND: Multiple Sclerosis (MS is the most common demyelinating disease. An autoimmune basis has been confirmed for pathogenesis of MS. Prolactin (PRL has roles in these mechanisms. Its serum levels change in MS according to some reports. The purpose of this study was to survey these changes in MS patients. METHODS: Sixty MS patients were included in this cross-sectional study. The same number of controls matched for sex and age were studied. Pregnant, lactating women, consumers of specific medications and patients with underlying diseases were excluded from our study. RIA was used for determination of serum levels of PRL. RESULTS: In this study, PRL level in male patients was 14.23 ± 11.47 ng/ml compared to controls with mean level of 7.21 ± 4.12 ng/ml (P value <0.001. Mean PRL level in female patients was 20.18 ± 11.04 ng/ml whereas controls had a mean level of 14.45 ± 6.93 ng/ml (one-tailed P value <0.05. So there were significant differences in serum PRL level between case and control groups in both men and women CONCLUSIONS: PRL has a positive relation with MS in both sexes. Further studies for determination of causality relation and drug effect in endocrine system on MS pathogenesis are suggested. KEY WORDS: Multiple Sclerosis, prolactin, male, female

    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.

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.

    To investigate the pathophysiological role of thrombopoietin (TPO) in thrombopoiesis, we measured its serum levels in 15 healthy individuals, 84 patients with various hematological diseases and 2 patients with liver cirrhosis using an enzyme immunoassay procedure. The TPO level was 0.84 +/- 0.40 f mol/ml in normal individuals. TPO levels were considerably elevated in patients with myelosuppression after intensification chemotherapy of acute leukemia in complete remission (postchemotherapy group; n = 18; 18.46 +/- 9.70 f mol/ml). When the data of normal individuals and the postchemotherapy group were combined, TPO levels were inversely correlated with the platelet count in this combined group. We compared these data of normal individuals and the postchemotherapy group with various hematological disease states. In aplastic anemia (n = 13; 16.03 +/- 9.44 f mol/ml), acute lymphoblastic leukemia (n = 5; 10.36 +/- 5.57 f mol/ml), malignant lymphoma (n = 6; 2.79 +/- 2.27 f mol/ml), multiple myeloma (n = 3; 3.34 +/- 0.20 f mol/ml) and chronic lymphocytic leukemia (n = 2; 1.71 +/- 3.91 f mol/ml), the relationship of serum TPO levels and platelet counts was almost the same as in the combined group with normal individuals and the postchemotherapy group. However, the TPO levels were slightly higher in myeloproliferative disorders (n = 12; 1.99 +/- 1.47 f mol/ml) and lower in acute myelogenous leukemia (n = 8; 2.27 +/- 1.25 f mol/ml), hypoplastic leukemia (n = 3; 2.76 +/- 2.23 f mol/ml), myelodysplastic syndrome (n = 2; 0.42 +/- 0.60 f mol/ml), liver cirrhosis (n = 2; 1.50 +/- 0.92 f mol/ml) and idiopathic thrombocytopenic purpura (n = 12; 2.08 +/- 1.41 f mol/ml), when compared to the regression line for the combined group with normal individuals and postchemotherapy group. These findings suggest that TPO might play an important role in regulation of the platelet count in normal and pathological conditions. PMID:8888496

    Serum fucose and sialic acid levels were determined in 50 oral cancer patients and 25 healthy controls. A statistically significant increase was noted in the study group. The increase in serum fucose level correlated well with the clinical staging in the study group whereas sialic acid did not. These values were independent of age, sex and histopathological grading. The result suggest that the serum fucose level is a better biochemical tumor marker than sialic acid level. However its usefulne...

    Febrile convulsion is the most common disorder in childhood with good prognosis. There are different hypotheses about neurotransmitters and trace element changes in biological fluids which can have a role in pathogenesis of febrile convulsion. In this study, serum selenium, zinc, and copper were measured by atomic absorption spectrometry in the children with febrile convulsion (n = 30) and in the control group (n = 30). The age and sex of the subjects were registered. Selenium and zinc were found to be significantly lower in febrile convulsion cases than in the control group (p < 0.0001 and p < 0.0001, respectively). There was no significant difference in the value of copper between the two groups (p = 0.16). While selenium and zinc levels were 44.92 +/- 10.93 microg/l and 66.13 +/- 18.97 microg/dl in febrile convulsion, they were found to be 62.98 +/- 9.80 microg/l and 107.87 +/- 28.79 microg/dl in healthy children. Meanwhile, copper levels were 146.40 +/- 23.51 microg/dl in the patients and 137.63 +/- 24.19 microg/dl in the control group, respectively. This study shows that selenium and zinc play an important role in the pathogenesis of febrile convulsion. PMID:19669113

    Full Text Available Secondary hyperparathyroidism (SHPT is a common, important, and treatable complication of end-stage renal disease. This study was conducted to investigate the role of serum magnesium (Mg in regulating the secretion of parathyroid hormone (PTH by the parathyroid gland in patients on maintenance hemodialysis (HD. Pre-dialysis serum levels of calcium (Ca, phosphorus (P, Mg, alkaline phosphatase (ALP, intact serum PTH (iPTH, serum 25-hydroxy Vitamin D (25-OH Vit D and plasma bicarbonate (HCO3 were measured. The Urea Reduction Rate as well as duration and dosage of HD treatment were noted. Our study did not show any significant correlation between serum Mg levels and duration of HD treatment, levels of serum ALP, and plasma HCO3, Ca and P. An inverse correlation, albeit insignificant, was found between the serum Mg levels and iPTH (r=-0.30 p=0.079; also, a significant positive correlation was found between serum Mg levels and serum 25-OH Vit D levels (r= 0.40 p= 0.009. Our findings are in agreement with previous data, which suggest that factors other than serum Mg are more important in the regulation of PTH secretion in HD patients. A positive and strong association between serum Mg with 25-OH Vit D needs to be studied in greater detail.

  13. The low TSH level in blood serum

    International Nuclear Information System (INIS)

    The low TSH level in blood serum (0.38 - 4,8 mμ/l) and the frequency of cross-reactions dictate the need for a sensitive and specific assay method. The IRMA (immunoradiometric assay) technique meets the requirements for high sensitivity and specificity. In the present study work was done to determine the characteristics of the IRMA-TSH (Netria-Batan) kit which makes use of the ''sandwich'' technique. Samples/standards were reacted with excess I-125 labelled monoclonal antibodies against TSH (Ab*), the free and the bound Ab* fraction were separated using solid phase antibody. The result showed that the IRMA-TSH (Netria-Batan) kit has abord working range (0.2 - 550 mμ/I) and a Low blank (Bo) value (0.8%-0.095%), high precision (with in assay CV less than 10%, and between assay CV less than 15%) high sensitivity (detection limit 0.04 mμ/l), and high accuracy (recovery 94,1%). High specificity of the kit was assured by the use of monoclonal anti-TSH with low cross reaction (0.008% against hCG, 0.7% against LH and 1.7% against FSH (1). (author). 7 figs.; 7 refs

    Porcine reproductive and respiratory syndrome (PRRS) is the most economically important disease to the swine industry, and effective prevention strategy for this disease is still required. Guanylate-binding protein 1 (GBP1) and myxovirus resistance protein 1 (Mx1) are two important proteins belonging to the GTPase superfamily that have been previously described to show antiviral effects. CD163 is considered the most important receptor for PRRSV attachment and internalization. Therefore, the aim of the present study was to evaluate the effects of these genes on host resistance against PRRSV infection in conjunction with the host immune response following PRRSV challenge. The results showed that pigs with AG genotype for the GBP1 exon2 exhibited a significantly higher average daily weight gain (ADWG) and lower average viremia than AA or GG genotype. Furthermore, pigs harbouring the AG genotype for the GBP1 gene presented greater CD4(+)CD25(+) and CD8(+)CD25(+) T cell populations at 4 and 18 days post challenge (dpc), respectively, as compared with other genotypes whereas pigs with CC genotype for the CD163 gene displayed significantly higher nucleocapsid-specific antibody titers at 11dpc. However, pigs with a single 11-bp deletion or insertion in the Mx1 gene did not show significant differences in either weight gain or viremia. Based on these results, we concluded that GBP1 is most significantly associated with resistance against PRRSV infection and efficient T cell activation in pigs. PMID:26711047

  16. Serum leptin levels in female patients with niddm

    International Nuclear Information System (INIS)

    Objective: To compare serum leptin levels of diabetic and non-diabetic female subjects and also assess the relationship of hyperglycemia with serum insulin, C-peptide and leptin levels. Results: Serum leptin levels of obese diabetic and non-diabetic subjects were significantly higher as compared with lean diabetic patients and non-diabetic subjects (P<0.05). Leptin levels were positively correlated with serum insulin and C-peptide levels. Serum leptin increased with increase in body mass index and waist hip ratio was strongly related with insulin resistance in NIDDM. Conclusion: Leptin levels are increased in obesity and may play a role in development of insulin resistance and NIDDM. (author)

    Full Text Available BACKGROUND: We have previously investigated the microlocalisation of M1 and M2 macrophages in NSCLC. This study investigated the non-macrophage (NM expression of proteins associated with M1 and M2 macrophages in NSCLC. METHODS: Using immunohistochemistry, CD68(+ macrophages and proteins associated with either a cytotoxic M1 phenotype (HLA-DR, iNOS, and MRP 8/14, or a non-cytotoxic M2 phenotype (CD163 and VEGF were identified. NM expression of the markers was analysed in the islets and stroma of surgically resected tumours from 20 patients with extended survival (ES (median 92.7 months and 20 patients with poor survival (PS (median 7.7 months. RESULTS: The NM expression of NM-HLA-DR (p<0.001, NM-iNOS (p = 0.02 and NM-MRP 8/14 (p = 0.02 was increased in ES compared to PS patients in the tumour islets. The tumour islet expression of NM-VEGF, was decreased in ES compared to PS patients (p<0.001. There was more NM-CD163 expression (p = 0.04 but less NM-iNOS (p = 0.002 and MRP 8/14 (p = 0.01 expression in the stroma of ES patients compared with PS patients. The 5-year survival for patients with above and below median NM expression of the markers in the islets was 74.9% versus 4.7% (NM-HLA-DR p<0.001, 65.0% versus 14.6% (NM-iNOS p = 0.003, and 54.3% versus 22.2% (NM-MRP 8/14 p = 0.04, as opposed to 34.1% versus 44.4% (NM-CD163 p = 0.41 and 19.4% versus 59.0% (NM-VEGF p = 0.001. CONCLUSIONS: Cell proteins associated with M1 and M2 macrophages are also expressed by other cell types in the tumour islets and stroma of patients with NSCLC. Their tissue and cellular microlocalisation is associated with important differences in clinical outcome.

  2. Racial difference in serum Vitamin B12 levels

    International Nuclear Information System (INIS)

    Measurements of the serum Vitamin B12 concentrations of 49 black and 49 white healthy adults demonstrate a significantly higher mean serum Vitamin B12 level in blacks when compared to whites. The reason for this difference appears to be genetic, although environmental factors may also be involved. It is suggested that clinical laboratories should establish their own separate reference values of serum Vitamin B12 for blacks and whites in order to prevent misinterpretation of test results

    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.

Diabetes mellitus was defined as fasting glucose ≥126 mg/dL, nonfasting glucose ≥200 mg/dL, or use of oral hypoglycemic medication or insulin (=395. In multivariable logistic regression models, we found that higher serum uric acid levels were inversely associated with diabetes mellitus after adjusting for age, sex, race/ethnicity, education, smoking, alcohol intake, body mass index, hypertension, and serum cholesterol. Compared to quartile 1 of serum uric acid, the odds ratio (95% confidence interval of diabetes mellitus was 0.48 (0.35–0.66; trend <0.0001. The results were consistent in subgroup analysis by gender and hypertension status. Higher serum uric acid levels were inversely associated with diabetes mellitus in a representative sample of US adults.

  9. Changes in serum leptin level in patients with diabetic retinopathy

    International Nuclear Information System (INIS)

    Objective: To explore the regulation of changes in serum leptin level in patients with diabetic retinopathy. Methods: The 120 participating subjects were of four groups: healthy controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR, each group consisted of 18 males and 12 females with comparable BMI. The levels of serum leptin, IVC, insulin and blood glucose of these patients were measured and the correlation between serum leptin level and other parameters was analysed. Results: The level of serum leptin in controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR were 6.91 ± 1.87 μg/L, 7,83 ±2.11 μg/L, 9.56 ± 2.43 μg/L and 11.69 ± 2.57 μg/L respectively. The patients with PDR had higher serum leptin levels than patients with NPDR (t=2.15, p < 0.05), diabetic patients without retinopathy (t = 2.71, p < 0.01), and controls (t = 3.50, p < 0.001), the patients with NPDR had higher serum leptin levels than diabetic patients without retinopathy (t = 2.23, p < 0.05) and controls (t = 2.75, p < 0.01), while the difference in serum leptin was not significant between diabetic patients without retinopathy and controls. The serum level was positively correlated to BMI (r = 0.22, p < 0.05) and FINS (r = 0.28, p < 0.01). Conclusion: Serum leptin level is elevated in patients with diabetic retinopathy and is positively correlated to the severity of the disease

    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.

  11. Serum organochlorine levels and history of lactation in Egypt

    International Nuclear Information System (INIS)

    We conducted a study in Egypt to assess the determinants of organochlorine serum levels among premenopausal women and the risk of premenopausal breast cancer for women with high organochlorine serum levels. We included 69 breast cancer patients and 53 controls consisting of visitors to the hospitals of the cancer patients. We found low levels of dichlorodiphenyldichloroethylene (DDE), total dichlorodiphenyltrichloroethane, and β-hexacholorhexane (β-HCH) in most subjects. Mean DDE levels were 12.7±20.3 ppb for cases and 16.6±30.1 ppb for controls (P=0.60); β-HCH levels were 2.1±3.8 ppb for patients and 2.1±3.9 ppb for controls (P=0.71). Interestingly, subjects with low levels had breast fed their children for an average period of 18 months. Women with no lactation history had much higher organochlorine levels than women who breast fed (P=0.002 for DDE). Younger age, older age at first childbirth, and shorter duration of breast feeding were significant predictors of higher levels of serum DDE levels. Younger age, older age at first childbirth, and higher body mass index were significant predictors of higher β-HCH levels. This study suggests that organochlorine serum levels in Egyptian women are quite low, but indicates an effect of breast feeding in eliminating organochlorines, which would imply exposure to children. Organochlorine serum level was not a risk factor of breast cancer in this population

    Full Text Available INTRODUCTION AND AIM: Patients who are admitted to hospital with pneumonia are at risk of subsequent recurrent pneumonia and death even after discharge. This risk may be even higher in patients, who have a low serum albumin level on admission. This study was conducted to determine serum albumin level in patients with CAP as compared to healthy individuals and to observe the correlation of serum albumin level with severity of CAP. METHODOLOGY: This study was carried in department of TB-chest at Gandhi medical college, Bhopal. The study includes 30 cases of CAP and 30 age and sex matched healthy controls. The cases were divided according to CRB-65- BTS criteria, in less severe pneumonia group A (score0-1, n=16, moderate pneumonia group B (score2-3, n=8, very severe pneumonia group C (score4, n=6. The serum was assayed quantitatively for albumin in biochemistry department and compared statistically. RESULTS: Patients with CAP have low levels of serum albumin (mean value 2.91±0.09 gm/dl and this value further decreases significantly with increasing severity of pneumonia (p<0.001. In control group, mean value of serum albumin was 3.21±0.10g/dl with no significant effect of age and sex. In pneumonia cases, serum albumin shows decreasing trend along with increasing severity of pneumonia with statistically significant (p<0.001 difference in mean serum albumin level in all three CAP groups with different level of severity. CONCLUSION: Serum albumin may be a good easily available and cheap indirect marker of not only nutritional status of the patient but also, it can be correlated with severity of community acquired pneumonia and thus prognosis.

    Full Text Available Background and Design: Psoriasis is a chronic, recurrent, T-cell mediated inflammatory skin disease with multifactorial etiology. It was shown that visfatin, an adipocytokine, induces expression of the tumor necrosis factor-a (TNF-a, interleukin (IL-1b, IL-6 ve IL-8 in previous studies. In the present study, we aimed to investigate serum visfatin levels and relation between visfatin and psoriasis severity.Material and Method: Forty psoriatic patient and 40 healthy controls were included in this study. Serum visfatin, IL-6, TNF-a and CRP levels were measured in all participant and PASI scores of the psoriatic patients were estimated. Results: The mean serum visfatin and IL-6 levels were not statistically different in psoriatic patients compared with controls (p=0.509 and p=0.213. Serum TNF-a levels were significantly higher in patients with psoriasis than in healthy controls (p=0.015. There was no statistically significant difference in CRP levels between two groups (p=0.370. However, there was positive correlation between PASI scores and serum visfatin or CRP levels respectively (p=0.001, p=0.002. The positive correlation was also found between serum visfatin and CRP levels (p=0.029. Conclusion: These results demonstrated that visfatin may not play a significant role in the immunopathogenesis of psoriasis but visfatin could be accepted as a nonspecific inflammatory marker to correlated severity of the disease.

    Chaojun Qi

    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

  19. Assessment of Serum Vitamin D Levels in Hypertensive Patients

    International Nuclear Information System (INIS)

    High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

    Abstract Recently, hepcidin, an antimicrobial-like peptide hormone, has evolved as the master regulator of iron homeostasis. Despite the growing evidence of iron imbalance in childhood-onset ischemic stroke, serum hepcidin level in those patients has not yet been researched. In this study, we aimed to estimate serum (hepcidin) level in acute ischemic stroke (AIS) patients and to investigate whether subcutaneous enoxaparin sodium, which is a low-molecular-weight heparin (LMWH) derivative, could modulate serum hepcidin level in those patients. This was a case–control study included 60 (AIS) cases, and 100 healthy children with comparable age and gender as control group. For all subjects’ serum hepcidin, interleukin-6 (IL-6), and soluble transferrin receptor [sTfR]) levels were assessed by (enzyme-linked immunosorbent assay [ELISA] method). Iron parameters including (serum iron, ferritin, transferrin, and total iron binding capacity [TIBC]) were also measured. The patients were subdivided according to treatment with an LMWH derivative into 2 groups and serum hepcidin levels were assessed initially and 1 week after stroke onset for all cases. We found that AIS cases had higher serum iron, ferritin, and IL6 levels compared to the control group (all P  0.05). However, on the 7th day of diagnosis serum hepcidin level decreased significantly in AIS cases treated with LMWH (group 1) (median, 36 vs 21 ng/mL; P  0.05). Serum hepcidin showed significant positive correlations with serum iron, transferrin saturation, ferritin, and IL6 (r = 0.375, P < 0.05; r = 0.453, P < 0.05; r = 0.687, P < 0.01; r = 0.515, P < 0.01; respectively). Our data brought a novel observation of elevated serum hepcidin level in pediatric AIS patients and pointed out that treatment with LMWH could modulate hepcidin level in those patients.

    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.

  8. Study of serum osteocalcin levels in patients with hyperthyroidism

    International Nuclear Information System (INIS)

    In order to study the serum osteocalcin (OC) level in hyperthyroidism, serum osteocalcin, FT3, FT4 and TSH were measured by radioimmunoassay in 87 patients with hyperthyroidism and 52 healthy volunteers. The results indicated that the serum osteocalcin level was decreased with age increasing in healthy volunteers and there was no significant difference in sex (P > 0.05). Serum concentration of OC was significantly higher in untreated hyperthyroid patients than that in healthy volunteers (P 3, FT4(FT3:r 0.84 - 0.27, P 4:r = 0.58 - 0.29, P < 0.01), but not with TSH. Conclusion: Thyroid hormones might speed up bone turnover directly with increased bone resorption to induce bone mass loss. These results indicate that OC is a highly sensitive marker for altered bone metabolism in hyperthyroidism

    Adipokines have a significant effect on metabolism, immunoinflammatory responses as well as on carcinogenesis; therefore, we aimed at evaluating their potential predictive and prognostic significance in lung cancer. Eighty patients--mean age 62.9 ± 9.2 years--with previously untreated lung cancer (61 NSCLC and 19 SCLC) of all stages and 40 healthy individuals were enrolled in this study. Serum levels of leptin, adiponectin and ghrelin were measured using human Radioimmunoassay kits. Serum leptin levels in lung cancer patients were lower compared to control (p < 0.0001), while adiponectin and ghrelin levels were significantly increased in patients (p = 0.0003 and p = 0.0043, respectively). Additionally, the leptin/adiponectin ratio was significantly lower in the patients group compared to controls (p < 0.0001]. There was no association between serum levels of adipokines and any of the patient clinicopathological characteristics or response to therapy. Nevertheless, patients with lower values of serum leptin had shorter overall survival (p = 0.014), whereas multivariate analysis revealed leptin levels as an independent prognostic factor for survival (p = 0.024, HR 0.452, CI 95 % 0.232-0.899). These results suggest that adipokines may play a role in the pathogenesis of lung cancer, while leptin serum levels might provide useful prognostic information. PMID:23430445

    In this study serum homocystein (Hcy) level was measured and its relationship with disease activity criteria and treatment protocols was investigated in ankylosing spondylitis (AS) patients. Ninety-two AS patients and 58 healthy individuals were recruited. Erythrocyte sedimentation rate and serum C-reactive protein were determined. Bath AS disease activity index and Bath AS functional index were calculated. Serum Hcy levels >15 micromol/l were considered as hyperhomocysteinemia. The mean serum homocysteine levels were 14.40 and 12.60 micromol/l in patients with AS and the control group, respectively, and the difference between two groups was significant. While there was no significant difference between the sulfasalazine (SSZ) group with 14.25 micromol/l mean Hcy level and the methotrexate (MTX)/SSZ group with 16.05 micromol/l, there was a statistically significant difference between the Hcy levels of these two groups and Hcy level of 12.15 micromol/l of the non-steroidal anti-inflammatory drugs group, and 12.60 micromol/l Hcy level of the control group. Mean serum Hcy level was 13.65 micromol/l in patients with active AS and 14.60 micromol/l in patients with inactive AS, and there was no significant difference between the groups. In our study serum Hcy level was found to be significantly higher in patients with AS than in healthy control subjects. Especially for the AS patients receiving MTX and SSZ treatment without folic acid supplementation, addition of folic acid to their therapy may decrease the risk of cardiovascular disease which in turn decreases the mortality in these patients, but further prospective studies are needed for supporting these results.

    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. "n"nMethods: In this study 42 patients in Imam Dialysis Center were chosen and their serum IL-6 levels were measured at 2 times at three month interval and at the same time blood sample analysis were done for the following: Alb CPR, Ca, P, PTH, TIBC, Ferritin, TG, Chol, LDL, HDL, Uric Acid, Hb, WBC and urea."n"nResults: The mean serum level of IL-6 in hemodialysis patients was 6.35±4.47pg/ml (minimum: 0.55, maximum: 18.25 with the normal range of 1.3±3.2pg/ml."n"nConclusions: The IL-6 level was higher than normal range in the 52% of the patients.

    Full Text Available Background. Procalcitonin (PCT is a useful surrogate marker for the differentiation of postoperative infection and unspecific inflammatory reaction after surgery. It is known that postoperative course of the PCT serum level varies with type of surgery. No data exists about the postoperative course of serum PCT levels after primary total hip replacement (THR. Purpose. To characterize early postoperative serum PCT levels in uneventful primary THR compared to postoperative levels of different frequently used inflammatory blood parameters. Method. We prospectively investigated 31 patients. Blood samples were taken preoperatively and for 5 days postoperatively. PCT levels were compared with C-reactive protein (CRP, interleukin-6 (IL-6, and blood leucocyte counts (WBC. Results. In uneventful THR PCT levels showed a uniform low-level course with a peak at the second postoperative day. At the fifth day values returned to almost preoperative levels. On contrary, CRP levels remained high during the entire observational period. Only IL-6 levels showed a peak at postoperative day one with a quick and uniform return to preoperative levels. Conclusion. Similar to observations in cardiothoracic, intestinal, and neural surgeries, postoperative course of PCT after primary THR showed a uniform low-level course with a peak at the second postoperative day but below expected levels in systemic infections.

    Background 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. Design 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. Results 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. Conclusion 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 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.

    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. PMID:25456880

    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.

    There are conflicting reports on the correlation between serum selenium (Se) levels with rheumatoid arthritis (RA). Through a meta-analysis approach, the aim of the present study is to clarify the relationship between serum Se levels with RA. We searched literatures that met our predefined criteria in PubMed, ScienceDirect, and OVID published as of September 2015. Ten eligible articles with 14 case-control studies involving 716 subjects were identified. Overall, pooled analysis indicated that subjects with RA had lower serum levels of Se than the healthy controls (standardized mean difference (SMD) = -1.347, 95 % confidence interval (CI) = [-1.872, -0.823], p meta-analysis supports a significant association between low serum Se concentration with RA. However, this finding needs further confirmation by a trans-regional multicenter study to obtain better understanding of causal relationship between serum Se with RA of different human races or regions.

  12. Changes of serum leptin levels in rat models of septicemia

    International Nuclear Information System (INIS)

    Objective: To investigate the role played by leptin in acute traumatic inflammation with determination of the changes of serum leptin levels in rat models of septicemia. Methods: Forty rat models of septicemia were prepared with ligation and artificial perforation of caecum. These models were divided into four equal-numbered groups: (1) no further treatment (2) intraperitoneal injection with 2ml intralipid (3) intraperitoneal injection with 0.025mg estradiol in 2ml solution (4) subcutaneous injection with 0.5u insulin in 2ml solution. Ten other animals underwent sham operation with laparotomy only. Serum leptin levels were determined in all the fifty rats 12h later with a method of RIA developed in this laboratory. Results: Compared with the serum leptin in the sham operation groups, the leptin levels in the intralipid group increased and in the other three groups decreased, but all not significantly. However, the levels in the intralipid group were significantly higher than those in the group without further treatment and the estradiol group (P<0.05). Conclusion: In rat models of septicemia, endogenous expression of leptin was decreased with lower serum levels. Early energy supplement might increase the leptin expression. Intervening the hypothalamus-pituitary-adrenal cortex axis function with exogenous estradiol or reduction of energy reserve with insulin would decrease the leptin expression with less protection against inflammation.

    Full Text Available Objective. To evaluate the effect of maternal smoking during pregnancy on levels of umbilical cord erythropoietin. Methods. 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.

    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 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.

    CYFRA 21-1 is a fragment of cytokeratin 19 (CK 19). Four patients with large intrahepatic (or peripheral) cholangiocarcinoma (CC) and high serum levels of CYFRA 21-1 (normal, vitamin K absence or antagonist II (PIVKA II) were elevated in all HCC patients (AFP, PIVKA II, respectively; normal range, < or = 10.0 ng/ml and < or = 0.1 AU/ml) CYFRA 21-1 levels were measured twice or three times during the clinical course in 2 CC patients and in 6 HCC patients, and increased gradually with tumor growth in the 2 CC patients and in 3 of the 6 HCC patients. Marked increases in serum CYFRA 21-1 levels in patients with large liver cancers, particularly in those with normal levels of AFP and PIVKA II, would suggest the existence of intrahepatic CC rather than HCC.

    Background: Candida species are normal mycoflora of human body which are capable to cause urinary tract infection (UTI). Mannose-binding lectin (MBL) is a kind of innate immune system and decreasing plasma levels of MBL may disrupt the natural immune response and increase susceptibility to infections. Objectives: The aim of the present study was to assess MBL in the serum of patients with candiduria and compare them with control. Patients and Methods: The blood and urine samples were collected from 335 patients (hospitalized in Golestan hospital, Ahvaz) using standard methods and the growing colonies on CHROMagar were identified using routine diagnostic tests. MBL activity in the serum of 45 patients with candiduria and 45 controls was measured using Eastbiopharm enzyme-linked immunosorbent assay (ELISA) kit. Results: In this study, 45 (13.4 %) urine samples were positive for Candida species (17 males and 28 females). The most common isolated yeast was Candida albicans (34%), followed by C. glabrata (32.1%), C. tropicalis (9.4%), other Candida species (22.6%), and Rhodotorula species (1.9%). The mean serum levels of MBL were 0.85 ± 0.01 ng/mL and 1.02 ± 0.03 ng/mL among candiduric patients and controls, respectively, and there was no significant difference between the two groups (P = 0.6). Conclusions: Our results showed that there was no significant relationship between MBL serum levels and candiduria. PMID:26870314

    The absorption of etofenamate (CAS 30544-47-9, Rheumon gel) by iontophoresis in 11 patients with low back pain and in 13 patients with synovitis of the knee was evaluated. During the 5-day treatment period, the test gel in a quantity corresponding to 100 mg etofenamate was applied to affected body regions every day by 20-min iontophoresis sessions. Two hours after the fifth application, the concentration of etofenamate in serum and synovial fluid (in patients who had knee joint iontophoresis) were measured by HPLC. Iontophoresis of etofenamate into the lumbar region as well as to the knee joint resulted in consistent serum levels: 219 +/- 136.3 micrograms/l and 191 +/- 84.6 micrograms/l, respectively. In patients with synovitis of the knee, the synovial level of etofenamate (368 +/- 109.2 micrograms/l) was almost twice as high than the serum concentration. The authors conclude that with topical application of etofenamate by iontophoresis the drug appears not only in the serum but also--with higher levels--in the synovial fluid. PMID:11455681

    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.

    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 (Iranian patients. PMID:26329996

    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.

    Full Text Available Febrile seizures are the most common cause of convulsions in children and a frequent cause of emergency hospital admissions. Indian studies suggested that up to 10% of children experience a febrile seizure. Febrile seizures are defined as an event in infancy or childhood usually occurring between 6 months to 6 years of age associated with fever but without evidence of intracranial infection or defined cause. OBJECTIVES: To determine the frequency of low serum zinc level in children presenting with febrile seizures at tertiary care hospital, Bangalore. METHOD: This is an observational cross sectional study conducted at the Department of Pediatric Medicine, tertiary care hospital, Bangalore, from January 2013 to January 2014. Children (6 months to 6 years of age presenting with febrile seizures who satisfied inclusion and exclusion criteria were enrolled for the study. Cause of fever was determined after detailed history, physical examination and relevant investigations. Three milliliters centrifuged blood sample was preserved in acid washed test tube. Separated serum was used to measure serum zinc level by calorimetric method. RESULTS: Out of 100 children enrolled, male to female ratio was 1.4:1, 56% of children were below the age of 2 years with mean age of the children was 24 months. Upper respiratory tract infection was the most frequent cause of fever apparent in 70 children (70%, followed by dengue fever 11 children (11%, acute gastroenteritis 6 (6%, urinary tract infection and otitis media in 4 children each (8%, Viral fever in 5 child (5%. Frequency of low serum zinc level was 62% in children with febrile seizures. INTERPRETATION AND CONCLUSION: This study reveals that there is positive correlation between low serum zinc levels and febrile convulsions.

  6. Effect of body mass index on serum leptin levels

    International Nuclear Information System (INIS)

    Background: Leptin is product of ob gene, an adipose tissue derived hormone that plays a key role in the regulation of body fat mass by regulating appetite and metabolism while balancing energy intake and energy expenditure. The objective of the study was to evaluate possible association between serum leptin levels and Body Mass Index (BMI) of gender in adult age group. Methods: Two-hundred-seventy subjects aged 20-50 years were randomly selected from general population of Abbottabad. The subjects were grouped on the basis on BMI (89 normal, 92 overweight, and 89 obese). After complete evaluation, demographic data was recorded and BMI. Non-fasting venous blood samples were drawn to measure serum leptin and serum glucose levels. The data were analysed using SPSS-15 calculating mean, percentage, independent t-test and chi-square test. Correlation and regression curve analysis were obtained, and p and r values were calculated. Results: Serum leptin levels and differences between genders were significant in all body mass indices. For normal BMI group the mean values for leptin were 2.6+-1.5 gamma g/ml in men, and 17.3+9-10.2 gamma g/ml for women. For Group-2 mean leptin levels in men were 9.9+-6.8 gamma g/ml and in women were 34.8+-13.6 gamma g/ml. For Group-3 BMI comprising obese subjects mean values for men were 21.3+-14.2 gamma g/ml and for women were 48.21+-21.2 gamma g/ml (p<0.001). Conclusion: A progressive increase in serum leptin concentration was observed with an increase in BMI. Significant difference between leptin concentrations in either gender was found in normal, overweight and obese subjects. (author)

  7. The serum lipid peroxide level of civil aircrew members

    International Nuclear Information System (INIS)

    Objective: To observe serum lipid peroxide level and antioxidant capacity in civil aircrew members who occupationally exposed to cosmic radiation at high altitude. Methods: Serum lipid peroxides (MDA), superoxide dismutase (SOD) and total antioxidant activity (TAO) were all determined by chemical colorimetry. The effective doses were estimated in accordance with CARI-6. Results: The three indicators in the aircrew members were all significantly higher than those of ground personnel (P<0.05): their MDA, SOD, TAO levels were (4.09±1.1) nmol/ml, (126.0 ± 17.1)U/ml, (22.01 ± 4.6) U/ml, while those in the ground personnel were (3.79±0.7) nmol/ml, (119.5±10.5) U/ml, (20.02±3.9) U/ml, respectively. The serum MDA levels exhibited a trend of increase with average annual flight hours and average annual effective doses, but were not parallel with total hours service in flying and accumulative effective doses and ages. The MDA showed corresponding dynamic changes with the changes in the flight continuity over a recent period of time. Conclusions: The lipids in the body of aircrew members suffer oxidation damage from cosmic radiation and the antioxidant capacity of the body shows a compensatory increase. The serum lipid peroxide levels are affected obviously by flight burdens and the frequency exposed to cosmic radiation recently. The serum lipid peroxides might be used as a monitoring indicator in cosmic radiation protection for aircrew members

  8. Radioimmunoassay of serum digoxin levels in digitalis intoxication

    International Nuclear Information System (INIS)

    For 101 hospitalized patients where clinical symptoms of a glucosidine intoxication as a consequence of oral digoxin treatment were noted, serum digoxin levels were determined using a RIA kit of the Boehringer company (I-125 tracer, solid phase tube separation technique) on a fasted stomach prior to oral drug administration. An ECG was performed simultaneously and in addition kidney function parameters and electrolyte levels were determined. An anamnesis and clinical examination of the patients were also conducted. Interferences in the RIA method and gastro-intestinal illness resulting in changes in resorption behaviour were excluded. The group of patients showed collectively an average serum digoxin level of 2.9 +- 0.9 ng/ml with a range from 1.8 to 6.8 ng/ml, which was statistically significantly higher than the average value for 101 patients receiving long-term oral medication but without symptoms of glycosidine intoxication. According to the manufacture's specifications for the RIA kit, values > 2.0 ng/ml are considered as toxic, with values between 1.6 and 2.0 ng/mg falling into a ''grey zone''. A correlation was found between toxic serum values with changes in ECG pattern and subjective clinical symptoms of intoxication. A limitation of kidney function was responsible for the high serum glycoside levels in 62% of the patients. It was shown that the differing response of patients towards digitalis medication, above all in the case of long-term therapy, warrants an RIA determination of serum glycoside values in order to adjust the digoxin dose to individual requirements.

    INTRODUCTION: Activation of liver macrophages plays a key role in liver and systemic inflammation and may be involved in development and prognosis of acute-on-chronic liver failure (ACLF). We therefore measured the circulating macrophage activation markers soluble sCD163 and mannose-receptor (s......-C AD-scores. Addition of the macrophage markers to the clinical scores improved the prognostic efficacy: In ACLF patients sCD163 improved prediction of short-term mortality (C-index:0.74(0.67-0.80)) and in patients without ACLF sMR improved prediction of long-term mortality [C-index:0.......80(0.76-0.85]. CONCLUSIONS: The severity related increase in sCD163 and sMR and close association with mortality suggest a primary importance of inflammatory activation of liver macrophages in the emergence and course of ACLF. Accordingly, supplementation of the macrophage biomarkers to the platform of the clinical scores...

    Iodine uptake by the thyroid and serum triiodothyronine (T/sub 3/) level in subjects aged from 65 to 93 years were determined. Low T/sub 3/ level and normal uptake of inorganic iodine by the thyroid were found. In the light of these results it is suggested that normal accumulation of inorganic iodine and low production of T/sub 3/ are characteristic features of euthyroidism in elderly subjects. It is believed that the function of the thyroid is expressed better by determination of the serum levels of thyroid hormones than determination of the uptake of radioactive iodine. Elaboration of standard normal values which would take into account abnormalities encountered in old age is postulated.

    Accumulating data suggest that depression is associated with risk factors for cardiovascular disease, but few studies have investigated potential behavioral mediators of such associations, particularly among women. In this study of healthy young adult women (n = 225), we examined associations among depressive symptoms, health behaviors, and serum lipid levels. Depressive symptoms were assessed with the 20-item Center for Epidemiologic Studies-Depression scale, and a fasting blood sample was obtained for serum lipid levels, including total cholesterol, high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C). Diet was measured using 24-h recalls, and other health behaviors (physical activity, smoking) were assessed via self-report questionnaire. Results indicated a modest negative association between depressive symptoms and LDL-C levels. Higher levels of depressive symptoms were also associated with lower total and insoluble dietary fiber intake, both of which were associated with HDL-C and LDL-C. Mediational analyses indicated a significant indirect effect of depressive symptoms on LDL-C via total and insoluble dietary fiber in unadjusted analyses, but not in adjusted analyses. The present findings suggest that depressive symptoms are inversely associated with serum LDL-C levels in young adult women, but that these associations are not likely mediated by adverse lifestyle behaviors.

    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.

    Objective:To determine whether blood nitrite levels are elevated in patients with leptospirosis. Methods: Male patients fulfilling clinical and epidemiological criteria for a diagnosis of leptospirosis were recruited. Those with MAT titre of≥400 together with those seroconverting to a titer of≥200 were included in the analysis. Serum nitrite levels were measured in these patients and age, sex matched healthy controls. Results:Patients from 3 hospitals (n=75) were screened during a 3 month period from 28th June to 3rd September 2009, of whom 20 were eligible for the study. Serum nitrite levels were found to be significantly higher in patients with acute leptospirosis [n=20, (0.359±0.229)μM] compared to controls [(n=13,(0.216±0.051)μM] (P=0.014). A significant correlation was also observed between the MAT titre and the day of illness (r = 0.547; P<0.0001). Conclusions: Serum nitrite levels are higher in patients with acute leptospirosis compared to age and sex matched controls. No correlation could be assessed with severity of illness, as sample size was inadequate to determine this.

    Background Previous studies have implicated the important and active role of vitamin D in the immune system. Objectives The aim of this study was to evaluate serum levels of 25-hydroxyvitamin D in children with burn injuries. Materials and Methods In this cross-sectional study, 118 patients with various degrees of burn injuries were enrolled. A checklist consisting of demographic data, total body surface area (TBSA) affected by burn, degree of burn, serum level of 25(OH)D, total protein, albumin, electrolytes, and parathyroid hormone was recorded for each patient. Results Sixty-eight (57.6%) males and 50 (42.4%) females with a mean age of 4.04 years (SD = 3.04) were evaluated. The mean level of 25(OH)D was 14.58 ng/mL (SD = 6.94). Levels of 25(OH)D in four (3.39%) cases were higher than 30 ng/mL, while 95 (81.35%) cases had levels lower than 20 ng/mL, and 19 (16.10%) cases had levels of 21 - 30 ng/mL. The level of 25(OH)D was below recommended levels in 96.61% of cases, while 81.34% had vitamin D deficiency and 16.1% had insufficiency. We found a significant correlation between vitamin 25(OH)D and total protein, albumin, and total and ionized calcium (P children suffering from severe burns were low. Supplementation might be useful in patients with very low levels of serum vitamin D.

    Background The relationship between inducible nitric oxide synthatase activity and disease severity in leptospirosis is unclear. Nitric oxide is converted to nitrites and nitrates, thus nitrite and nitrate levels (NOx) in serum are considered surrogate markers for nitric oxide. NOx are excreted through the kidneys, and elimination is diminished in renal impairment. We assessed the correlation of NOx with disease severity in patients with leptospirosis, compared with healthy controls and non-l...

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

    Full Text Available (Received 26 August, 2009 ; Accepted 18 Novamber, 2009AbstractBackground and purpose: Occult hepatitis B infection (OBI is a form of hepatitis in which despite the absence of detectable HBsAg, HBV-DNA is present in peripheral blood of patients. Investigators believed that the genetics and immunological parameters may be different in resistant individuals and patients. Cytokines, such as IL-12, could be leading to alteration in viral immune response. 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

Dickkopf related protein 1(DKK-1,as an end ogenous inhibitors of the canonical Wnt/–catenin path ways pecific to bone and Osteoprotegerin(OPG,have been demonstrated to be key molecules involved in bone erosion and bone remodeling.The present study aimedto evaluate DKK-1 and OPG in women with osteoporosis to predict activity and severity of this common disease. METHODS: The study population included 44 women with osteoporosis and 44 controls with normal bone mineral density (BMD. Serum levels of DKK-1 and OPG were measured by standard methods. RESULTS: The serum Dkk1 concentration in the osteoporosis group (2.91 ± 1.27 was significantly increased compared to the control group (2.07 ± 0.87 (P < 0.010. The serum concentration of OPG was significantly higher incontrol group than patients (4.70 ± 2.16 vs. 4.56 ± 1.21; P = 0.005. CONCLUSIONS: Although the results of this study indicate that DKK-1 and OPG may play different roles in the pathogenesis of osteoporosis, the increase of DKK-1 level and its correlation with FN-BMD might be related to disease activity and bone remodeling in osteoporosis.

    Full Text Available To evaluate the maternal serum dehydroepiandrosterone (DHEA sulfate levels as a factor influencing labor ‘efficiency’ at term and unsuccessful labor induction. This is a prospective study. In this study the mean (± standard error maternal serum DHEA sulfate levels of 90 singleton pregnant women in 3 groups with spontaneous labor, need for augmentation and need for induction were compared.Pregnancies complicated by diabetes mellitus, hypertension, fetal growth restriction, tobacco consumption, corticosteriod use or chorioamintis were excluded. Bishop score of all cases was less than 5. Serum DHEA sulfate levels were measured by radioimmunoassay. Dehydroepiandrosteone sulfate levels and other obstetric variables were correlated retrospectively with the clinically determined requirements of oxytocin augmentation of labor, and the outcome of each induction attempt. The t-test, Variance analysis Kruskal –Wallis test, Mann-Whitney test, chi-square (X2 distribution, linear correlation and regression were used for statistical analysis. P<0.05 was considered statistically significant. This study showed that the mean (± standard error maternal serum DHEA sulfate level was not significantly higher in women who progressed spontaneously through labor (n=30 than in those who required augmentation (n=30 (60.78±4.22 versus 70.38±5.84.

    Full Text Available BACKGROUND: The involvement of liver in dengue fever is not uncommon as reported in literature since 1970. Liver and nervous system involvement simultaneously predicts poor outcome in dengue fever. Atypical manifestations include liver involvement with elevation of enzymes, central nervous involvement (encephalopathy and cardiac alterations (myocarditis. Liver involvement in dengue fever is manifested by the elevation of transaminases representing reactive hepatitis, due to direct attack of virus itself or the use of hepatotoxic drugs. OBJECTIVE OF THE STUDY: Study of serum aminotransferase levels in dengue fever. METHODOLOGY: In this descriptive, cross sectional study, all patients who presented to the Department of medicine with dengue IgM positive were included. Study period of 24 months from July 2010-June 2012, patients attending to M.S. Ramaiah medical college were included (n=166. RESULTS: 166 patients reactive for dengue virus specific IgM antibody were studied. As per WHO classification, 137 (82.5% patients were classified as dengue fever, 20 (12% as dengue hemorrhagic fever, and 9 (5.4% as dengue shock syndrome. Mean age of dengue infection patients was 35.71 ±12.9 (SD years, with male to female ratio nearly equal. Hepatic dysfunction is very common in all forms of dengue infection, with AST rising significantly more than ALT. Serum aminotransferase levels appear to have a directly proportional correlation with grading of dengue infection. Hyperbilirubinemia, elevated transaminases, hypoproteinemia, hypoalbuminemia and deranged coagulation profile were seen in higher frequency in DHF and DSS group as compared to classical DF group. AST and ALT were significantly higher in patients with secondary infection (IgM & IgG positive as compared to primary infection (IgM positive. CONCLUSION: Serum aminotransferase levels are significantly raised in all forms of dengue infection and it directly correlates with severity of infection. Serum

    This study aimed to investigate the prohepcidin levels in premature newborns with oxygen radical diseases such as bronchopulmonary dysplasia, retinopathy of prematurity and necrotizing enterocolitis and to compare these levels with those of healthy premature newborns. Eighty premature infants (25-34 weeks gestational age) were enrolled. The patient group was composed of 38 premature babies with oxygen radical diseases, and the control group consisted of 42 healthy premature newborns. Complete blood count, serum iron and ferritin concentrations, iron-binding capacity (IBC), transferrin and prohepcidin levels were measured. The mean ferritin and prohepcidin levels were higher in the patient group than in the control group (p = 0.038 and p = 0.022, respectively). No significant correlations were found between serum prohepcidin levels and iron parameters. We believe that this finding will contribute to a greater understanding of the etiopathogenesis of oxygen radical diseases. There is a need for future studies to explore the link between underlying inflammatory mechanisms and hepcidin in oxygen radical diseases. PMID:25363011

    Recent evidence suggests that vitamin D deficiency has harmful effects on health and that recent vitamin D intake recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, fractures, cancer prevention, incident hypertension and mortality. For all endpoints, levels in the deficient range (nmol/l; ng/ml) are associated with no benefit or adverse effects, while the most advantageous serum levels for 25(OH)D appeared to be close to 75 nmol/l (30 ng/ml). An intake of 800 IU (20 microg) of vitamin D3 (cholecalciferol) per day for all adults may bring 97% of the population to level of at least 50 nmol/l and about 50% up to 75 nmol/l. Thus, higher doses of vitamin D than currently recommended are needed to bring most individuals to75 nmol/l. While estimates suggest that 1600 to 2000 IU vitamin D3 per day may successfully and safely achieve this goal, the implications of higher doses for the total adult population need to be addressed in future studies.

    Full Text Available Glycoproteins play a significant role in neoplastic transformations. Both the levels of fucose and the activity of fucosyl transferase, which mediates the assembly of the oligosaccharide moieties of the glycoprotein chains, have been found to be elevated in neoplastic conditions. Since these elevations are common features of a variety of neoplastic cells, these two have been designated as non-specific markers of malignancy. In the present study, the fucose level and fucosyl transferase activity were determined in the sera of cancer patients and an attempt was made to establish a relationship between the two. It was found that both the fucose levels and fucosyl transferase activities showed considerable elevation in the five cancer groups studied, establishing them as useful diagnostic parameters. However, it was also observed that the rate of increased fucosyl transferase activity was not fully reflected in the resulting serum fucose levels in a few cases.

    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.

    Full Text Available Background and Objectives: The Magnetotactic bacteria Magnetospirillum gryphiswaldense (MSR-1 mineralizes the magnetite (Fe3 O4 crystals and organizes a highly ordered intracellular structure, called the magnetosome. Iron transport system supports the biogenesis of magnetite. Although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron will cause many diseases. Mice were infected by MSR-1 to study survival of bacteria in mice when injected by different routes. The aim of this study was to investigate whether bacterial magnetite formation could take up Fe2+ ions from the blood an animal model.Materials and Methods: In this study, MSR-1 at a dose lower than LD50 in 200 μl volume of PBS buffer was injected as intravascular (i.v, peritoneal (i.p and subcutaneous (s.c in mice. Number of viable bacterial was determined in organs such as liver, spleen and lymph node by measuring colony-forming unit (CFU. Moreover, serum iron level was evaluated by using commercial kits.Results and Conclusion: According to CFU measurements, after 96 hours, mice can clear MSR-1 from their body with different routes of injection. We have also shown that MSR-1 bacteria can affect the blood iron level in mice. The serum iron level decreased from control level in the first 24 h after i.v injection (P < 0.05. Our research on optimizing the biological magnetic system is still continuing.

    The antimicrobial peptide cathelicidin LL-37 possesses antituberculous activity, its association with other mycobacterial diseases, such as leprosy, is unknown. We studied serum cathelicidin and 25OH-vitamin D3 levels in 29 leprosy patients and 19 healthy individuals from Yemen. Cathelicidin levels were significantly lower in both treated (n=15) and untreated leprosy patients (n=14) when compared to controls (P<0.001). Within leprosy patients, levels were lower in those who very recently developed disease (untreated group) when compared to already treated patients (P<0.05). 25OH-vitamin D3 levels were not different between groups. The results suggest a potential association of cathelicidin LL-37 with Mycobacterium leprae infection. PMID:20887706

    Primary aldosteronism (PA) is one of the most frequent forms of secondary hypertension, associated with atherosclerosis and higher risk of cardiovascular events. Platelets play a key role in the atherosclerotic process. The aim of the study was to evaluate the platelet activation by measuring serum levels of soluble CD40L (sCD40L) and P-selectin (sP-selectin) in consecutive PA patients [subgroup: aldosterone-secreting adrenal adenoma (APA) and bilateral adrenal hyperplasia (IHA)], matched with essential hypertensive (EH) patients. The subgroup of APA patients was revaluated 6-months after unilateral adrenalectomy. In all PA group, we measured higher serum levels of both sP-selectin (14.29±9.33 pg/ml) and sCD40L (9.53±4.2 ng/ml) compared to EH patients (9.39±5.3 pg/ml and 3.54±0.94 ng/ml, respectively; pAPA, PA patients showed significant reduction of blood pressure (BP) values, plasma aldosterone (PAC) levels and ARR-ratio, associated with a significant reduction of sP-selectin (16.74±8.9 pg/ml vs. 8.1±3.8 pg/ml; pAPA patients (r=0.54; pAPA patients.

The objective of this study was to compare serum endocan levels in patients with restless legs syndrome (RLS and control subjects in order to elucidate whether RLS is associated with endothelial dysfunction. Methods: A total of 31 drug naïve female patients with RLS and 31 age- and BMI-matched women were included in the study. Patients with pathological or physiological conditions or with a history of medication use that could potentially influence endothelial functions were excluded, as well as those with alcohol or drug abuse history. The two groups were compared with routine blood tests and serum endocan levels. Results: Patients with RLS had lower serum endocan levels than the controls (P=0.037. There was a negative bivariate correlation between RLS severity score and serum endocan levels (r=-0.406, P=0.023. While white blood cell count was significantly higher in RLS group, 25-hydroxy vitamin D3, vitamin B12, transferrin saturation rate, and HDL-cholesterol were significantly lower. Creatininemia and diastolic blood pressure were also marginally insignificantly lower in RLS group. Due to the presence of differences between two groups in these variables, a linear regression analysis was performed that showed a positive association between endocan and creatininemia (β=0.310, P=0.022, and a negative association between endocan and RLS (β=-0.502, P<0

  19. Serum ferritin level for estimating the effect of the radiotherapy

    International Nuclear Information System (INIS)

    Serum ferritin level was evaluated as a marker for estimating the effect of the radiotherapy. The ferritin level was determined by a radioimmunoassay (SPAC ferritin kit) in sera obtained serially from 37 patients with various malignant neoplasma before and after radiotherapy. The changes in the ferritin level were investigated in comparison with various clinical findings. The decision for significant changes in the ferritin level was made by the sensitivity which is a difference value necessary to discriminate 2 values at confidence level of 95%. Out of 11 cases with clinical evidence of distant metastasis, the ferritin level was decreased in only one case (9%) and increased or unchanged in the rest. On the other hand, out of 26 cases without evidence of metastasis it was decreased in 9 cases (35%) and unchanged in 12 cases (46%). The ferritin level was either decreased (64%) or unchanged (36%) in all the 11 cases with operation prior to radiotherapy, while out of 26 cases without operation (inoperable) it was decreased in only 3 cases (12%). In all 5 cases with radiosensitive tumors as judged by tumor size, the ferritin level was either decreased (40%) or unchanged (60%). Out of 28 cases with radioresistant tumors it was decreased in only 4 cases (14%). All of these results indicated that serial measurements of the ferritin level is useful for estimating the therapeutic effectiveness in radiotherapy. (author)

    A 66-year-old woman presented after an episode of accidental trauma with a painful ulcer on her scalp which rapidly enlarged in size, accompanied by central necrosis and undermining ulceration. The patient's past history was negative for underlying systemic disease, although she had had a similar post-traumatic intractable leg ulcer 3 years prior, which was unresponsive to surgical management but successfully treated with systemic steroids. A biopsied specimen from the scalp showed marked neutrophilic infiltrates in the dermis, compatible with a diagnosis of pyoderma gangrenosum (PG). The large ulcerative lesion responded very well to oral steroid therapy, showing rapid epithelialization. Serum levels of granulocyte colony-stimulating factor and interleukin-6 were significantly elevated prior to treatment, with decrease to normal levels after treatment. Serum tumor necrosis factor (TNF)-α and granulocyte macrophage colony-stimulating factor levels were within normal limits. The significance and pathogenic role of cytokine burst in PG is reviewed and discussed. PMID:26047254

  1. Alteration of serum estrogen levels in pregnant mares

    International Nuclear Information System (INIS)

    The estrogen levels in the peripheral blood serum of 5 mares were estimated by readioimmunoassay throughout their gestation period. Blood samples were collected from jugular veins, and the radioimmunoassay method, originated by Makino, had sufficient accuracy and reliability for the estimation. The result obtained was summarized as follows. The serum concentration of E, remained below 40 pg/ml from Day 0 to Day 75, then increased to 190.5 pg/ml on Day 120, and sharply up to the average value of 3682.2 pg/ml on Day 210, and the high levels continued for about a month. It then declined sharply towards 107.9 pg/ml on Day 300, with the fluctuation around Day 255 to 270. The E2 concentration showed the similar pattern to that of E1: it remained below 15.2 pg/ml from Day 0 to Day 75, 46.5 pg/ml on Day 120, then began to increase rather sharply up to Day 210, and the average highest value obtained was 1740.6 pg/ml. From around Day 210, the average E2 concentration remained high for about 2 months, then it declined sharply to 71.3 pg/ml on Day 285. The E3 level showed large variation within and among individuals, and no correlation was observed throughout the gestation period. (Kobatake, H.)

    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.

    The level of the third component of complement was measured in serial specimens of serum taken from thirty-one patients with acute viral hepatitis. Fourteen of the thirty-one patients were positive for the hepatitis-associated antigen. A characteristic fluctuation was observed in twenty-nine of the thirty-one patients. This consisted of an initial fall of the level of C3, followed by an increase to a higher than normal level and then a gradual return to normal. No difference was observed between the patients who were positive and those who were negative for the hepatitis-associated antigen. These results support the view that immune complexes play a significant role in the pathogenesis of acute viral hepatitis. PMID:4624985

    In patients with coronary artery disease (CAD), though aspirin inhibits platelet activation and reduces atherothrombotic complications, it does not always sufficiently inhibit platelet function, thereby causing a clinical situation known as aspirin resistance. As hyperuricemia activates platelet turnover, aspirin resistance may be specifically induced by increased serum uric acid (SUA) levels. In this study, we thus investigated the association between SUA level and aspirin resistance in patients with CAD. We analyzed 245 consecutive patients with stable angina pectoris (SAP) who in coronary angiography showed more than 50% occlusion in a major coronary artery. According to aspirin resistance, two groups were formed: the aspirin resistance group (Group 1) and the aspirin-sensitive group (Group 2). Compared with those of Group 2, patients with aspirin resistance exhibited significantly higher white blood cell counts, neutrophil counts, neutrophil-to-lymphocyte ratios, SUA levels, high-sensitivity C-reactive protein levels, and fasting blood glucose levels. After multivariate analysis, a high level of SUA emerged as an independent predictor of aspirin resistance. The receiver-operating characteristic analysis provided a cutoff value of 6.45 mg/dl for SUA to predict aspirin resistance with 79% sensitivity and 65% specificity. Hyperuricemia may cause aspirin resistance in patients with CAD and high SUA levels may indicate aspirin-resistant patients. Such levels should thus recommend avoiding heart attack and stroke by adjusting aspirin dosage. PMID:26656902

    The pulsatile release of cortisol from the adrenal glands is controlled by a hierarchical system that involves corticotropin releasing hormone (CRH) from the hypothalamus, adrenocorticotropin hormone (ACTH) from the pituitary, and cortisol from the adrenal glands. Determining the number, timing, and amplitude of the cortisol secretory events and recovering the infusion and clearance rates from serial measurements of serum cortisol levels is a challenging problem. Despite many years of work on this problem, a complete satisfactory solution has been elusive. We formulate this question as a non-convex optimization problem, and solve it using a coordinate descent algorithm that has a principled combination of (i) compressed sensing for recovering the amplitude and timing of the secretory events, and (ii) generalized cross validation for choosing the regularization parameter. Using only the observed serum cortisol levels, we model cortisol secretion from the adrenal glands using a second-order linear differential equation with pulsatile inputs that represent cortisol pulses released in response to pulses of ACTH. Using our algorithm and the assumption that the number of pulses is between 15 to 22 pulses over 24 hours, we successfully deconvolve both simulated datasets and actual 24-hr serum cortisol datasets sampled every 10 minutes from 10 healthy women. Assuming a one-minute resolution for the secretory events, we obtain physiologically plausible timings and amplitudes of each cortisol secretory event with R (2) above 0.92. Identification of the amplitude and timing of pulsatile hormone release allows (i) quantifying of normal and abnormal secretion patterns towards the goal of understanding pathological neuroendocrine states, and (ii) potentially designing optimal approaches for treating hormonal disorders.

  6. Clinical significance of determination of serum leptin levels in patients with type 2 diabetes mellitus

    International Nuclear Information System (INIS)

    Objective: To investigate the relationship between levels of serum leptin and levels of blood sugar, lipid as well as degree of obesity in patients with type 2 diabetes mellitus (DM2). Methods: Serum leptin levels were determined with RIA in 42 patients with DM2 and 38 controls. Results: The serum leptin levels in DM2 patients were significantly higher than those in controls (P <0.001) and were positively correlated with serum INS, TC, TG, LDL-C levels as well as BMI. Conclusion: High level of serum leptin was associated with obesity, high blood lipid levels and insulin resistance (IR). (authors)

    We herein report two cases of AIHA (autoimmune hemolytic anemia), a 25-year-old woman and a 77-year-old man, who presented with normal serum LDH values. Though in these two cases, low hemoglobin and haptoglobin, high total bilirubin and positive direct Coombs' test results led to the diagnosis of AIHA, both patients had normal LDH levels (218 and 187 IU/l). Both cases were successfully treated with prednisone. In the diagnosis of AIHA, elevated LDH is usually used as a marker of hemolysis. However, medical records of 24 AIHA patients collected in our institute from January 2001 to August 2012 revealed LDH levels to have been normal in 25% of these cases. This report indicates the importance of obtaining complete information about the blood testing of patients and taking these data into account when considering the diagnosis of AIHA. PMID:26666722

    It is well known that preeclampsia is associated to high uric acid levels, but the clinical assessment of this relationship is still under consideration. Our research was to evaluate if periodic doses of uric acid during pregnancy might help to identify a high risk group prior to the onset of preeclampsia. We conducted a retrospective investigation in 79 primary gestates with normal blood pressure and 79 women with preeclampsia who were assisted at Hospital Nacional Posadas during 2010. Serum uric acid levels, creatininemia, uremia, and proteinuria data from the clinical records of the pregnant women were considered. Uric acid levels were similar in both groups during the first half of gestation. However, as of the 20th week, uric acid increased 1.5-times in preeclamptic women with no changes in creatinine and urea, confirming that these patients had no renal complications. Furthermore, we noted that higher levels of uric acid correlated with low birth weight. We also observed that pregnant women with a family history of hypertension were more likely to develop this condition. Moreover, we did not find a direct relationship with the fetal sex or the appearance of clinical symptoms. The analytical evidence suggests that changes in uric acid concentrations may be due to metabolic alterations at the initial stages of preeclampsia. Therefore, we propose that monitoring levels of uric acid during pregnancy might contribute to the early control of this condition. PMID:25555007

  16. Serum leptin levels in patients with coronary artery disease

    International Nuclear Information System (INIS)

    Cardiovascular diseases (CVD) are the leading cause of morbidity, mortality and disability worldwide. Leptin, a 16kDa product of ob gene, is an endocrine hormone produced by white adipose tissue. It is primarily involved in the regulation of food intake and energy expenditure. Hyperleptinemia is one of the novel risk factors contributing in many ways to CVD. Objective: The objective of the study was to find the level of leptin in patients with coronary artery disease (CAD) and compare it with healthy people in our population. Methods: Our study was an analytical and cross-sectional study. Our study included 60 patients with a history of CAD and 60 healthy controls (aged 40-60 years, both sexes). Leptin levels were measured by ELISA. Results: Mean serum leptin level in patients was 11.48+-11.25 g/ml, while control group had a mean leptin level of 8.22+-8.01 g/ml (p=0.071). Conclusion: Leptin levels were higher in patients but the difference was non-significant. More studies are needed with larger sample size in our population. (author)

    Serum iron levels were studied in 50 patients with pre-eclampsia and the results were compared with 50 control cases. Their serum iron levels were found to be higher than the controls. Increase in serum iron was directly proportional to the increased levels of uric acid, urea and creatinine. Mean reticulocyte counts, plasma free haemoglobin and unconjugated bilirubin levels were also higher in these patients. It is suggested that haemolysis may be a major contributory factor for the increased...

    AIM: To determine whether Helicobacter pylori ( H pylori)infection caused hyperhomocysteinemia by altering serum vitamin B12, serum folate and erythrocyte folate levels and whether eradication of this organism decreased serum homocysteine level.METHODS: The study involved 73 dyspeptic H pylori positive patients, none of them had gastric mucosal atrophy based on rapid urease test and histology. Out of 73patients, 41 (56.2%) showed a successful eradication of H pylori 4 wk after the end of treatment. In these 41 patients, fasting serum vitamin B12, folate and homocysteine levels, and erythrocyte folate levels before and 4 wk after H pylorieradication therapy were compared.RESULTS: The group with a successful eradication of Hpylori had significantly higher serum vitamin B12 and erythrocyte folate levels in the post-treatment period compared to those in pre-treatment period (210±97 pg/mL vs 237±94 pg/mL, P<0.001 and 442±212 ng/mL vs 539±304 ng/mL, P = 0.024, respectively), but showed no significant change in serum folate levels (5.6±2.6 ng/mL vs 6.0±2.4 ng/mL, P= 0.341). Also, the serum homocysteine levels in this group were significantly lower after therapy (13.1±5.2 μmol/L vs 11.9±6.2 μmol/L, P = 0.002). Regression analysisshowed that serum homocysteine level was positively correlated with age (P = 0.01) and negatively with serum folate level before therapy (P = 0.003). CONCLUSION: Eradication of H pylori decreases serum homocysteine even in patients who do not exhibit gastric mucosal atrophy. It appears that the level of homocysteine in serum is related to a complex interaction among serum vitamin B12, serum folate and erythrocyte folate levels.

  5. Alteration in serum osteocalcin levels in patients with diabetic nephropathy

    International Nuclear Information System (INIS)

    The fact that bone mass density (BMD) is not useful for assessing fracture risk in diabetic patients (DM) seems problematic, because those populations are increasing in every country. Osteocalcin (OC) is synthesized by osteoblasts and is considered to be a marker of bone formation. The present study was carried out to evaluate the usefulness of OC as noninvasive biomarker of bone formation in diabetes mellitus type 2 (uncomplicated) and diabetic nephropathy. Immunoradiometric assay(IRMA) was used for the quantitative measurement of human intact OC both N-terminal and C-terminal fragments in the serum of the control and the studied groups. OC levels in the uncomplicated diabetic group were significantly lower while in the diabetic nephropathy group was significantly higher compared to control values . There was a weak negative correlation between OC and both fasting blood glucose and glycated Hb% in the diabetic group. In diabetic nephropathy patients, a weak positive correlation was observed between OC and protein creatinine ratio. The results concluded that changes in bone remodelling marker OC are present in both DM type 2 and diabetic nephropathy explaining osteopenia and osteoporosis observed in both cases.Therefore, an effective glycaemic control should be the hallmark of prevention and treatment of diabetes mellitus induced osteoporosis

  6. Serum Biotin Levels in Women Complaining of Hair Loss.

    Biotin is a coenzyme for carboxylase enzymes that assist various metabolic reactions involved in fatty acid synthesis, branched-chain amino acid catabolism, and gluconeogenesis important for maintenance of healthy skin and hair. Due to its availability, affordability, and effective marketing for this purpose, biotin is a popular nutritional supplement for treatment of hair loss. However, there are little data on the frequency of biotin deficiency in patients complaining of hair loss and on the value of oral biotin for treatment of hair loss that is not due to an inborn error of biotin metabolism or deficiency. The aim of this study was to determine the frequency and significance of biotin deficiency in women complaining of hair loss. Biotin deficiency was found in 38% of women complaining of hair loss. Of those showing diffuse telogen effluvium in trichograms (24%), 35% had evidence of associated seborrheic-like dermatitis. About 11% of patients with biotin deficiency had a positive personal history for risk factors for biotin deficiency. The custom of treating women complaining of hair loss in an indiscriminate manner with oral biotin supplementation is to be rejected, unless biotin deficiency and its significance for the complaint of hair loss in an individual has been demonstrated on the basis of a careful patient history, clinical examination, determination of serum biotin levels, and exclusion of alternative factors responsible for hair loss.

    Serum concentrations of zuclopenthixol were determined in a group of 20 patients treated with a depot preparation, zuclopenthixol decanoate in Viscoleo. Clinical assessments according to a Clinical Global Impression (CGI) scale, Comprehensive Psychological Rating Scale (CPRS), 16-item subscale for schizophrenia, and the UKU side effect scale were performed on 3 consecutive days of injection. The serum concentrations showed a limited individual variation and a high and significant correlation between dose and serum concentration. One patient had a particularly high serum concentration of zuclopenthixol. This patient also had an elevated concentration of the N-dealkyl metabolite, but a low concentration of the sulphoxide. For serum concentrations versus clinical state and side effects some significant correlations were found. All correlations were positive, which means that the higher the serum concentration the poorer the clinical state of the patient. We think that this probably reflects a common clinical pattern of increasing the dose, when the antipsychotic response is unsatisfactory. The study also showed that for moderately ill patients, who were given the optimum dose of drug, the subgroup of patients not experiencing side effects had significantly lower serum concentrations than the subgroup with side effects.

  8. Changes of serum leptin and other related hormones levels in simple obese children

    International Nuclear Information System (INIS)

    Objective: To measure the serum leptin concentration in simple obese children together with other four kinds of related hormones. Methods: Serum Leptin, Ins, T3, T4 and GH levels were measured by radioimmunoassay in thirty-eight obese children and thirty healthy controls. Results: The levels of serum leptin, Ins and T3 in obese group were dramatically higher than those in control group (all P 4 concentration between simple obese children and control group (P > 0.05), Serum GH levels was significantly decreased in simple obese children (P < 0.01). There was a positive correlation between serum leptin levels and lns levels (r = 0.46, P < 0.01). Conclusion: In simple obese children there were leptin resistance and endocrine metabolic disturbances, the later might be correlated with the increasing of serum leptin levels; It is suggested that Leptin resistance might play a key role in the development of obesity

    The influence of sodium valproate on serum levels of phenobarbital during combination treatment was studied in 29 children and 50 adults with epilepsy. Steady-state drug levels in serum were determined immediately prior to drug administration using immunoenzymatic analysis. The serum level/dose ratio of phenobarbital increased significantly (p less than 0.001) when sodium valproate was added to the treatment. The increase had a mean value of 50.9% in adults and 112.5% in children, suggesting marked interindividual variability in the intensity of the interaction. Almost half of the patients required a decrease in the dose of phenobarbital prescribed. The interaction was more pronounced in patients with high serum levels of phenobarbital, while the dose of phenobarbital and the serum levels and dose of sodium valproate did not seem to affect the extent of the interaction. Close monitoring of the serum levels of phenobarbital is recommended during simultaneous treatment with sodium valproate. PMID:3103264

  10. Clinical significance of serum gastrin level changes in helicobacter pylori associated gastroduodenal disease

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical significance of gastrin expression in Helicobacter pylori (Hp) associated gastro-duodenal diseases and the relationship between Hp infection and serum gastrin level in patients. Methods: Serum gastrin levels were determined with RIA in 46 patients with Hp infection and 33 patients without Hp infection. In Hp+ patients, serum gastrin levels were again determined after Hp eradication. Results: Serum gastrin levels in patients with Hp infection were obviously higher than those in patients without Hp infection (p<0.05). The serum gastrin levels decreased significantly after Hp eradication (p<0.05). Conclusion: Hp infection could result in increased levels of serum gastrin, which in turn could serve as an indicator of presence of Hp infection

  11. Study on the relationship between serum levels of leptin thyroid hormones

    International Nuclear Information System (INIS)

    Objective: To evaluate the relationship between serum levels of leptin and thyroid functional status. Methods: Serum leptin (with RIA) and pituitary-thyroid axis hormones (with CLIA) were measured in 75 euthyroid controls, 44 hyperthyroid subjects and 27 hypothyroid subjects. Results: The levels of leptin in euthyroid controls, hyperthyroid subjects and hypothyroid subjects were (5.40 ± 3.78) ng/ml, (5.99 ± 5.24) ng/ml and (5.59 ± 4.23) ng/ml respectively with no significant differences among them. The serum leptin levels were positively correlated with serum TSH levels (r=0.27, P<0.01). Conclusion: Thyroid function has no effect on serum leptin levels and TSH levels correlates closely with those of serum leptin. (authors)

  12. Clinical significance of determination of serum cortisol and insulin levels in neonates with asphyxia

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical significance of the changes of serum cortisol and insulin levels in neonates with asphyxia. Methods: Serum cortisol levels were determined with CLIA and serum insulin levels with RIA in 38 neonates with asphyxia (mild degree 20, advanced 18) and 30 controls. Results: 1) In mild cases, serum insulin levels were significantly higher than those in controls (p<0.01) and serum cortisol levels were very significantly higher (p<0.001). 2) In advanced cases, both serum insulin and cortisol levels were very significantly higher than those in the controls (p<0.001). Conclusion: Hypoxia in the neonates with asphyxia is a very severe stress and will induce hypersecretion of cortisol and hyperglycemia which is detrimental to the patients. However hypersecretion of insulin will result in hypoglycemia, which is also very damaging. Physicians in charge should be aware of these possibilities and deal with them appropriately

    2012-01-01

    Full Text Available Background/Aim. Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contrbute, in part, to the recently reported increased risk for systemic diseases, including an altered lipid metabolism. On the other hand, many people in the world are affected by hyperlipidemia, which is a known risk faktor for atherosclerosis. The aim of this study was to determine the relationship between periodontal disease and blood lipid levels. Methods. A total of 50 patients with periodontitis included in this study had no documented history of recent acute coronary events. The healthy, non-periodontal subjects (comparison group comprised 25 subjects. All the patients were periodontology examined and completed a medical history. Dental plaque index, probing depth, gingival index bleeding on probing and clinical attechment levels were recorded. Blood samples were taken on admission for measurements of serum total cholesterol, triglycerides, hight density lipoprotein cholesterol (HDL-cholesterol, and low density lipoprotein cholesterol (LDL-cholesterol. Results. The obtained results showed that mean levels of cholesterol (6.09 ± 1.61 mmol/L, triglycerdes (2.19+1.67mmol/l and LDL cholesterol (4.09 ± 1.40 mmol/L in individuals with periodontitis were higer, and levels od HDL (1.43 ± 0.51 mmol/L was lower than those of individuals without periodontitis (4.86 ± 1.37; 1.14 ± 0.71; 3.18 ± 0.64; 1.53 ± 0.32 mmol/L, respectively. Conclusion. This study confirms a significant relationship between periodontal disease, regardless its intensity, and blood lipid levels in the studied population. The results imply that periodontitis may be a risk factor and may contribute to the pathogenesis of atherosclerosis and cardiovascular diseases (CVD. However, future prospective randomized studies have to determine whether

    Objective To evaluate some risk factors for cardiovascular diseases in feeding and eating disorders, the degree of lipid abnormalities was investigated in a large Japanese cohort of different groups of feeding and eating disorders, according to the Japan Atherosclerosis Society Guidelines for the Prevention of Atherosclerotic Cardiovascular Diseases 2012 (JAS Guidelines 2012). Methods Participants in the current study included 732 women divided into four groups of feeding and eating disorders: anorexia nervosa, restricting type (AN-R); anorexia nervosa, binge-eating/purging type; bulimia nervosa (BN); and binge-eating disorder (BED). We measured the serum levels of total cholesterol, high-density-lipoprotein (HDL) cholesterol, and triglyceride in these participants. Low-density-lipoprotein (LDL) cholesterol and non-HDL cholesterol levels were also calculated. Results The concentrations of LDL cholesterol and non-HDL cholesterol were widely distributed in all groups. When the LDL cholesterol risk was defined as ≥120 mg/dL and the non-HDL cholesterol risk as ≥150 mg/dL, according to the JAS Guidelines 2012, the proportion of LDL cholesterol risk ranged from 29.6% (BN) to 38.6% (AN-R), and the proportion of non-HDL cholesterol risk ranged from 17.8% (BN) to 30.1% (BED). Conclusion The present findings suggest the existence of LDL cholesterol risk and non-HDL cholesterol risk in all groups of eating disorders. Given the chronicity of this condition, the development of elevated concentrations of LDL cholesterol and non-HDL cholesterol at an early age may increase the risk of cardiovascular diseases.

  15. Impact of age, gender and diabetes on serum lipid levels

    International Nuclear Information System (INIS)

    Objectives:To see the effects of age, gender and diabetes on serum lipid levels. Study type, settings and duration:Cross sectional analytical study conducted at PMRC Research Centre, Fatima Jinnah Medical College,Lahore from Jun-Dec 2011. Materials and Methods: One hundred type 2 diabetes mellitus and equal numbers of gender matched healthy controls were randomly selected for the study. After an overnight fasting, blood specimens were drawn for lipid profile where total cholesterol,high density lipoprotein cholesterol and triglycerides were measured by standard enzymatic endpoint methods and LDL-cholesterol by Friedweld's formula. Statistical analysis was done using SPSS-15. Results Odd ratios of age for total cholesterol (OR 1.198); high density lipoprotein cholesterol (OR 1.144); and low density lipoprotein cholesterol (OR 1.576) revealed that subjects aged 45 years or more had greater risk of having deranged lipid levels. Female gender had higher high density lipoprotein cholesterol (p 0.000); and triglycerides (p 0.001). Odd ratios of men for total cholesterol (OR 0.775); high density lipoprotein cholesterol(OR 0.183); and low density lipoprotein Cholesterol (OR 0.683) illustrated that men were significantly less prone to dyslipidemia than women. Odd ratio of diabetes for high density lipoprotein cholesterol (OR 1.802) suggested that diabetics had 1.8 times more risk of having low high density lipoprotein cholesterol. Conclusions: Diabetic females over 45 years of age have significantly high chances of having disturbed or high lipid profile. Policy message:All persons in general and diabetics in particular over the age of 45 years should be screened for dyslipidemia and informed using behavior change communication to prevent disease complications.

    Full Text Available Rabies is considered a fatal disease once clinical symptoms have developed. The aim of this study was to evaluate epidemiological aspects and immune response in patients attacked by domestic and wild animals and subjected to post-exposure rabies treatment with equine serum and associated vaccine. Thirty-three patients were evaluated; they were between 13 and 65 years old, 75.8% were male and 24.2% female, and from the Botucatu neighborhood. Twenty healthy control individuals with the same age range were also studied. Specific antibodies to equine immunoglobulins and IFN-gamma, IL-2, IL-4, and IL-10 production were evaluated by ELISA. IgM, IgE, IgG and subclasses, and rabies virus antibodies serum levels were determined by nephelometry and seroneutralization methods, respectively. No anaphylactic or serum sickness allergic reactions were observed in patients after treatment. Anti-equine IgG levels were significantly higher than those of IgM after 14 and 28 days of treatment. Protective antibodies to rabies virus > 0.5 UI/ml were detected in 84.6% and 75% of patients at days 14 and 28, respectively. IFN-gamma, IL-2 and IL-10 levels in patients before and 48h after treatment were significantly higher than in controls suggesting that both Th1 and Th2 cells were activated in the patients. Serum IgM levels were higher at day 14, and IgG2 and IgE levels were higher at day 28 of treatment. These results suggest that post-exposure rabies treatment in humans induces significant alterations in patient immune response characterized by increased levels of cytokines, serum levels of specific rabies virus antibodies, and the equine serum components employed in the treatment.

    2006-01-01

    The collectin surfactant protein D (SP-D) is an important component of the pulmonary innate immune system, but SP-D is also present on extrapulmonary epithelial surfaces and in serum, where it has been used as a biomarker for pulmonary disease states. In this study, we investigate the mechanisms...... 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 SP-D and metabolic variables. The Met11Thr variant explained a significant part of the heritability indicating that serum SP-D variance could be decomposed into non-shared environmental effects (e(2) = 0.19), additive genetic effects (h(2) = 0.42), and the effect of the Met11Thr variations...

  5. Detection of serum leptin levels in patients with viral hepatitis C

    International Nuclear Information System (INIS)

    To evaluate changes of serum leptin levels in patients with viral hepatitis C(HCV), serum leptin levels were determined by RIA in 65 patients with viral chronic hepatitis C and in 80 control subjects ,liver function (ALT, AST) , glucose (Glu) , and total cholesterol (TC) were evaluated too. Campared with controls, the levels of serum leptin were significantly increased in patients with HCV (P0.05). The levels of serum leptin increased in patients with HCV, which correlates positively with the severity of liver inflammation, so that leptin can be regarded as an index which reflects the severity of liver inflammation.

    Full Text Available This study was conducted on 300 mares kept under one of the two managemental conditions: field (individual management and farm (organizational management. Mares were categorized as estrual, fertile, subfertile or pregnant. Any possible relationship between fertility and serum levels of sodium, magnesium, phosphorus, potassium and calcium was investigated. The serum sodium level differed significantly (P<0.05 among all groups of mares at both conditions, with pregnant mares having the highest and subfertile the lowest levels. Also, independent of the condition, the pregnant mares had significantly higher (P<0.05 serum potassium levels compared with subfertile ones. Serum calcium levels were significantly higher in estrual mares when compared with those of pregnant mares under farm management or subfertile mares under field conditions. In each group, mares kept under farm management had significantly higher serum magnesium levels but significantly lower serum calcium levels than those of mares kept under field. In estrual group, mares raised under field condition had significantly higher serum phosphorus levels. These results sufficiently provide the foundation for more rigorous and controlled studies to establish a firm basis for fertility versus serum-mineral-profile relationship. Moreover, due to marginally adequate serum mineral levels in mares kept under both managements, supplementation with mineral mixture was recommended for optimum fertility.

  9. The clinical value of detection of serum TGAb and TPOAb level in autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    To study the clinical value of serum TGAb and TPOAb levels in the diagnosis of patients with autoimmune thyroid diseases (AITD), the serum levels of TGAb and TPOAb in 175 patients with AITD and 64 non-AITD patients and 57 health controls were measured by RIA. The results showed that the serum levels of TGAb and TPOAb in AITD patients with GD and HT were significantly higher than that of control group (P0.05). The detection of serum TGAb and TPOAb levels may have clinical value in the diagnosis, treatment and prognosis of autoimmune thyroid diseases. (authors)

  10. The clinical utility of serum ferritin levels in patients with malignant tumors treated by radiotherapy

    International Nuclear Information System (INIS)

    The serum levels of ferritin in 394 patients, including 339 patients with various malignant tumors and 23 with various non-malignant diseases, and 32 healthy subjects were determined. The normal levels of ferritin were 82.7 +- 42.3 ng/ml for males and 42.0 +- 36.9 ng/ml for females. The positive ratio of serum ferritin level was 28% in patients with malignant tumors and 22% in patients with non-malignant diseases. The usefulness of serum ferritin assay in screening for malignant tumors appeared to be limited. High serum levels of ferritin were found in patients with malignant lymphoma (positive ratio: 42%), pulmonary cancer (38%) and esophageal cancer (37%). According to the histological types, epidermoid cancer appeared to produce a higher serum level of ferritin than adenocarcinoma in patients with pulmonary cancer. It was interesting that malignant lymphoma had a high serum level of ferritin in spite of its low serum level of CEA. Carcinoma of the digestive tracts except for esophagus was considered to have a normal serum ferritin level in spite of the advanced stage. There was no close relationship between serum ferritin levels and CEA levels in patients with pulmonary cancer and breast cancer. Serum CEA assay was more useful for detection of tumors than serum ferritin assay in patients with breast cancer. Serum ferritin levels in patients with good prognosis decreased following radiation therapy, but those in patients with poor prognosis elevated or unchanged in spite of therapy. Therefore, serial ferritin determinations may be useful for evaluation of radiotherapy and assessment of prognosis. (J.P.N.)

    International Nuclear Information System (INIS)

    To explore the clinical significance of empty abdominal serum Cholyglycine(CG) levels on the diagnosis of patient with Intrahepatic Cholestasis of Pregnancy(ICP), the serum levels of CG, TBA, TBIL and ALT in 400 normal pregnant women and in 87 pregnant patients with ICP were analyzed retrospectively. The results showed that the serum CG levels of patients with ICP were significant higher than that of normal control (P<0.001). The positive rate of serum CG was 100%. The serum levels of TBA, TBIL and ALT in patients with ICP were slightly higher than that of normal controls. The positive rates of TBA, TBIL and ALT were 36.5%, 12.2% and 35.6% respectively. The serum CG levels may be regarded as an economical and sensitive indicator in diagnosis of patients with ICP in the earlier stage. (authors)

  12. A Clinical Study of Serum Thyroglobulin Levels in Patients with Thyroid Tumor

    International Nuclear Information System (INIS)

    Serum thyroglobulin (Tg) was measured by radioimmunoassay in 81 patients with thyroid tumor who were treated in the department of Internal medicine of National Medical Center from January, 1981 to June, 1982. The results were as follows: 1) The mean serum thyroglobulin level in thyroid tumor was significantly higher than normal subjects (p<0.001). 2) The mean serum thyroglobulin level in benign tumor was lower than malignant tumor (p<0.05). 3) The thyroid carcinoma with metastasis had significant high level of serum thyroglobulin than without metastasis (p<0.001). 4) The mean postoperative serum thyroglobulin level was significantly lower than preoperative level (p<0.001). Data from our study show that serum thyroglobulin determination is useful for assessing the presence of malignant thyroid tumor, metastasis and the extent of residual or recurrent thyroid cancer after surgery.

    2012-07-01

    Full Text Available Abstract Background Serum Krebs von den Lungen-6 (KL-6, which is classified as human mucin-1 (MUC1, is used as a marker of sarcoidosis and other interstitial lung diseases. However, there remain some limitations due to a lack of information on the factors contributing to increased levels of serum KL-6. This study was designed to investigate the factors contributing to increased levels of serum KL-6 by molecular analysis. Methods Western blot analysis using anti-KL-6 antibody was performed simultaneously on the bronchoalveolar lavage fluid (BALF and serum obtained from 128 subjects with sarcoidosis. Results KL-6/MUC1 in BALF showed three bands and five band patterns. These band patterns were associated with the MUC1 genotype and the KL-6 levels. KL-6/MUC1 band patterns in serum were dependent on molecular size class in BALF. Significantly increased levels of serum KL-6, serum/BALF KL-6 ratio and serum soluble interleukin 2 receptor were observed in the subjects with influx of high molecular size KL-6/MUC1 from the alveoli to blood circulation. The multivariate linear regression analysis involving potentially relevant variables such as age, gender, smoking status, lung parenchymal involvement based on radiographical stage and molecular size of KL-6/MUC1 in serum showed that the molecular size of KL-6/MUC1 in serum was significant independent determinant of serum KL-6 levels. Conclusions The molecular structural variants of KL-6/MUC1 and its leakage behavior affect serum levels of KL-6 in sarcoidosis. This information may assist in the interpretation of serum KL-6 levels in sarcoidosis.

  14. Glycosyl-phosphatidylinositol (GPI)-anchored membrane association of the porcine reproductive and respiratory syndrome virus GP4 glycoprotein and its co-localization with CD163 in lipid rafts

    International Nuclear Information System (INIS)

    The porcine reproductive and respiratory syndrome virus (PRRSV) glycoprotein 4 (GP4) resembles a typical type I membrane protein in its structure but lacks a hydrophilic tail at the C-terminus, suggesting that GP4 may be a lipid-anchored membrane protein. Using the human decay-accelerating factor (DAF; CD55), a known glycosyl-phosphatidylinositol (GPI) lipid-anchored protein, chimeric constructs were made to substitute the GPI-anchor domain of DAF with the putative lipid-anchor domain of GP4, and their membrane association and lipase cleavage were determined in cells. The DAF-GP4 fusion protein was transported to the plasma membrane and was cleaved by phosphatidylinositol-specific phospholipase C (PI-PLC), indicating that the C-terminal domain of GP4 functions as a GPI anchor. Mutational studies for residues adjacent to the GPI modification site and characterization of respective mutant viruses generated from infectious cDNA clones show that the ability of GP4 for membrane association corresponded to virus viability and growth characteristics. The residues T158 (ω − 2, where ω is the GPI moiety at E160), P159 (ω − 1), and M162 (ω + 2) of GP4 were determined to be important for virus replication, with M162 being of particular importance for virus infectivity. The complete removal of the peptide–anchor domain in GP4 resulted in a complete loss of virus infectivity. The depletion of cholesterol from the plasma membrane of cells reduced the virus production, suggesting a role of lipid rafts in PRRSV infection. Remarkably, GP4 was found to co-localize with CD163 in the lipid rafts on the plasma membrane. Since CD163 has been reported as a cellular receptor for PRRSV and GP4 has been shown to interact with this receptor, our data implicates an important role of lipid rafts during entry of the virus.

    Full Text Available PN is a secreted cell adhesion protein critical for carcinogenesis. Elevated serum levels of PN have been implicated as playing an important role in different types of cancer, and a few reports suggest a potential role as a prognostic marker. We evaluated the prognostic significance of preoperative serum PN concentration in patients with BCa receiving curative surgery. Enzyme-Linked Immunosorbent Assay (ELISA was performed to determine the preoperative serum PN level in 182 patients. The correlations between serum PN concentration with clinical pathological features and PN expression in primary tumor samples were analyzed. The prognostic impact of serum PN levels with all-cause and BCa-specific mortality was also investigated. Appropriate statistics were used. Elevated serum PN levels were significantly associated with patient age (p = 0.005, adjuvant systemic therapy (p = 0.04 and progesterone receptor (PgR status (p = 0.02. No correlation between PN preoperative serum levels and other clinical-pathological parameters, including either the epithelial or the stromal PN expression of primary tumor or the combination of the two, was found. Similarly, no association between serum PN levels and either all-cause or BCa-specific mortality was found. However, subgroup analysis revealed a correlation between higher PN serum levels and all-cause mortality in patients with node-negative disease (p = 0.05 and in those with a low PgR expression (p = 0.03. Higher levels of serum PN were also found to correlate with BCa-specific mortality in the subgroup of patients who did not receive any adjuvant systemic therapy (p = 0.04. Our findings suggest that PN was detectable in the serum of early BCa patients before surgery and increased base-line serum levels predicted worse long-term survival outcomes in specific subgroups of patients.

    The aim of this study was to investigate serum IL17 levels in patients with Crohn's disease (CD) and to investigate the relationship between serum IL17 levels with disease activity. Methods. Fifty patients with CD and sex- and age-matched 40 healthy controls were included in the study. The serum IL17 levels, complete blood count, blood chemistry, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels were measured, and Crohn's disease activity was calculated using Crohn's disease activity index (CDAI). Results. The mean serum IL17 level of CD patients did not differ from those of healthy controls (P > 0.05). There was no difference between the mean serum IL levels of active CD patients and of quiescent CD patients (P > 0.05). However, the mean IL17 level of active patients was lower than of control subjects (P = 0.02). Serum IL17 was not correlated with inflammatory markers (ESR, CRP, white blood count, platelet count, and albumin) and CDAI. Conclusions. Peripheral blood serum IL17 levels of CD patients were not higher than of healthy controls, and also, serum IL17 level was not correlated with clinical disease activity. Peripheral IL17 measurement is not a useful tool for detecting and monitoring Crohn's disease which is understood to have complex etiopathogenesis. PMID:25140070

  4. Relationship between serum insulin level and age and sex in 980 patients with essential hypertension

    International Nuclear Information System (INIS)

    Objective: To investigate the change of serum insulin level in essential hypertension patients and its relationship with age and sex. Methods: The levels of serum insulin were determined with radioimmunoassay in 980 essential hypertension patients and 120 controls. Results: The levels of serum insulin in the essential hypertension patients were significantly higher than those in the controls (t=4.280, P<0.01). However, there were no significant differences among the levels in different sex and age groups. The same held true for women before and after menopause as well as different stages of hypertension. Conclusion: The average serum insulin level in EH patients was significantly higher than the level in controls, and had positive correlation to mean arterial pressure. But no significant differences were found among different sex and age groups, so serum insulin could be a new independent risk factor of essential hypertension

    Objective: To measure the zinc level in fertile and infertile population and to find out relationship of serum and seminal plasma zinc levels and serum testosterone in oligospermic and azoospermic infertile men. Design: Comparative study. Place and Duration of Study: The Infertility Clinic, Jinnah Postgraduate Medical Center (JPMC), Karachi, from January 2002-July 2003. Patients and Methods: Fifty-eight primary infertile male subjects, without any treatment, who had regular unprotected intercourse for at least 12 months without conception with their partners, aged 20-40 years, having normal and regular menstrual cycles without any uterine pathology or hormonal disturbance were selected from Infertile Clinic, Jinnah Postgraduate Medical Center, Karachi. After semen analyses, they were grouped as, oligospermic (30), and azoospermic (28). Twenty-five known fertile male selected from general population (their spouse had given birth to a child within one year) and after semen analysis were taken as normospermic control group. Semen analyzed according to WHO criteria and serum and seminal plasma zinc was estimated by 5Br. PAPS colorimetric method. Serum testosterone, LH, and FSH were measured by ELISA, using kits supplied by Diagnostic System Laboratories (DSL), U.S.A. Results: The mean value for testosterone was significantly low in oligospermic, (8.04+0.76) and azoospermic subjects (7.14+0.27) as compared to normospermic (9.90+0.14) control groups (p<0.05, p<0.001 respectively), serum LH (p<0.05, p<0.001) respectively) and FSH (p<0.05) were significantly higher than normospermic control group. Serum and seminal plasma zinc levels was low in oligospermic, and azoospermic subjects when compared with normospermic control groups (p<0.05, p<0.001 respectively). This suggests its involvement in spermatogenesis and infertility in such patients. Seminal zinc level has weak correlation with testosterone in oligospermic (r=0.44, p<0.05) and with serum zinc in azoospermic

    Multivitamin preparations are commonly administered to regular dialysis treatment (RDT) patients. Serum Vitamin A was measured in 72 patients on RDT. Elevated serum Vitamin A levels (102.29 +/- 26.95 microgram/dl [3.57 +/- 0.94 mumoles/l]) were found in the dialysis population (normal 40.98 +/- 6.71 microgram/dl [1.43 +/- 0.23 mumoles/l]; P less than 0.0005). Serum Vitamin A levels increased with duration (months) of dialysis but not with frequency of dialysis (twice or thrice weekly). Patients taking a VitaminA-containing multivitamin preparation had higher serum Vitamin A levels than those on a non-Vitamin A supplemented diet. Bilaterally nephrectomized patients had the highest serum Vitamin A levels while patients with obstructive uropathy had the lowest levels. Serum Vitamin A levels did not correlate with symptoms of uremia. Positive correlations were found with serum levels of calcium, cholesterol and triglycerides. Patients receiving a Vitamin A supplement had higher serum cholesterol levels than non-supplemented patients. Vitamin A might be a factor in the high incidence of cardiovascular disease in RDT patients. We therefore advise discontinuing the long-term administration of Vitamin A-containing multivitamin supplements to patients on RDT. PMID:527272

  11. Clinical Significances of Serum Vitamin B12, Folate and Ferritin Levels in Patients with Malignant Tumors

    International Nuclear Information System (INIS)

    In order to evaluate the clinical significances of the serum vitamin B12, folate and ferritin levels in patients with malignant tumors, the levels were measured in 10 normal control subjects, 70 patients with malignant tumors, 7 patients with liver cirrhosis and 25 patients with other benign diseases. The results are as follows: 1) In normal control subjects, mean serum values for vitamin B12, folate and ferritin level were 588.80±131.58 pg/ml, 5.59±1.52 ng/ml and 89.22±42.78 ng/ml retrospectively. 2) There was no significant difference in serum levels between patients with benign diseases and normal control subjects. 3) The serum vitamin B12 and ferritin levels in patients with liver cirrhosis were significantly higher than in normal control, and the serum folate levels in these patients were lower than in normal control subjects. 4) The serum vitamin B12 and ferritin levels in patients with malignant tumors were significantly higher than in normal control subjects, and the serum folate levels in these patients were significantly lower than in normal control subjects. The above results suggest that the serum vitamin B12 and ferritin may be useful as tumor markers in patients with malignant tumors.

    We recently reported the presence of various cyclopropane fatty acids-among them, cyclopropaneoctanoic acid 2-hexyl-in the adipose tissue of obese women. The aim of this study was to verify whether the presence of cyclopropaneoctanoic acid 2-hexyl in human serum was associated with obesity or chronic kidney disease (both being related to dyslipidemia), and to find potential associations between the serum level of this compound and specific markers of the these conditions. The serum concentration of cyclopropaneoctanoic acid 2-hexyl was determined by gas chromatography-mass spectrometry (GC-MS) in non-obese controls, obese patients, obese patients after a 3-month low-calorie diet, and individuals with chronic kidney disease. Obese patients and those with chronic kidney disease presented with higher serum levels of cyclopropaneoctanoic acid 2-hexyl than controls. Switching obese individuals to a low-calorie (low-lipid) diet resulted in a reduction in this fatty acid concentration to the level observed in controls. Cyclopropaneoctanoic acid 2-hexyl was also found in foods derived from animal fat. Serum concentrations of triacylglycerols in the analyzed groups followed a pattern similar to that for serum cyclopropaneoctanoic acid 2-hexyl, and these variables were positively correlated with each other among the studied groups. Patients with hypertriglyceridemia-related conditions presented with elevated serum levels of cyclopropaneoctanoic acid 2-hexyl. Our findings suggest that its high serum level is related to high serum triacylglycerol concentrations rather than to body mass or BMI. PMID:27003900

  15. Serum leptin level and its significance in chronic renal failure hemodialysis patients

    International Nuclear Information System (INIS)

    To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

    International Nuclear Information System (INIS)

    To determine the influence of exercise on serum levels of myoglobin, serum levels of this protein were determined by RIA in 90 healthy men, divided as follows: (1) Basal control (no exercise) 25 cases; (2) Moderate exercise (after subject had been working for 12 h in Medicine Emergency Service) 19 cases, and (3) Intensive exercise: (a) football professional (45-min match) 10 cases; (b) football amateur (45-min match) 10 cases; (c) basketball professional (45-min match) 10 cases, and (d) basketball professional (90-min training) 16 cases. Our results led us to the following conclusions. (1) Moderate exercise, such as the usual daily work, does not modify myoglobin levels; (2) Myoglobin serum levels after exercise increase in nearly all individuals. They are higher in untrained people; (3) There seems to be a correlation between exercise intensity and increase of myoglobin serum levels, and (4) The detection of serum myoglobin by RIA may have a wide field of application for sport medicine.

    Full Text Available Objective. Despite considerable study, the relevance of leptin and adiponectin for atherosclerosis development is still unsettled. We investigated relations of serum leptin and adiponectin to serum C-reactive protein (CRP, using the INTERLIPID dataset on Japanese emigrants living in Hawaii and Japanese in Japan. Design and Methods. Serum leptin, adiponectin, and CRP were measured by standardized methods in men and women of ages 40 to 59 years from two population samples, one Japanese-American in Hawaii (83 men, 89 women and the other Japanese in central Japan (111 men, 104 women. Participants with CRP >10 mg/L were excluded. Results. Sex-specific multiple linear regression analyses, with log-transformed leptin and adiponectin (log-leptin, log-adipo, site (Hawaii = 1, Japan = 0, SBP, HbA1c, smoking (cigarettes/day, and physical activity index score of the Framingham Offspring Study as covariates, showed that log-leptin directly related and log-adipo inversely related to log-CRP for both sexes (Ps < 0.05 to <0.01. Addition to the model of BMI and interaction terms (BMI × log-leptin, BMI × log-adipo, SITE × log-leptin, SITE × log-adipo resulted in disappearance of statistical significance except for direct relation of log-leptin to log-CRP in men (P=0.006. Conclusions. Leptin directly related to CRP independent of BMI and other confounding factors in men but not in women.

  1. Clinical significance of serum leptin levels in patients with graves' disease

    International Nuclear Information System (INIS)

    Objective: To investigate the levels of serum leptin in patients with graves' disease. Methods: Serum leptin levels were measured with IRMA in 51 patients with hyperthyroidism as well as 46 hypothyroid and 50 euthyroid subjects as controls. Serum TSH, free T3 and free T4 (FT3 and FT4) were also measured. Body fat percentage (% Fat) and body mass index (BMI) were calculated. Results: Serum leptin levels were significantly lower in patients with graves' disease (male 2.05 ± 1.54μg/L, female 7.47±5. 08 μg/L), than those in hypothyroid and euthyroid subjects. Levels in hypothyroid patients were significantly higher than those in controls, however, excluding the body fat factor, there were no obvious difference. Serum leptin levels in all the 3 groups were significantly positively correlated with BMI. The levels were negatively correlated with FT3, FT4 levels and positively correlated with TSH levels but both were not significant. Serum leptin levels were 2-3 times higher in women than in men among all 3 groups. Conclusion: Thyroid functional status affected serum leptin levels indirectly through the amount of body fat.

    Abstract Low levels of serum vitamin D are common in patients with mood disorders and stroke. It has been shown that low levels of serum vitamin D indicate a risk of depression in post-stroke subjects. Our aim was to determine the relationship between vitamin D and post-stroke anxiety (PSA). A consecutive series of 226 first acute ischemic stroke patients were recruited and followed up for 1 month. Serum levels of vitamin D were measured within 24 hours of admission. Patients with significant clinical symptoms of anxiety and a Hamilton anxiety scale score >7 were diagnosed as having PSA. In addition, 100 healthy subjects were recruited as controls and underwent measurements of serum vitamin D. A total of 60 patients (26.55%) showed anxiety at 1 month. Both PSA patients and non-PSA patients had lower serum levels of vitamin D than healthy subjects. A significant relationship was found between PSA and serum levels of vitamin D. Low serum levels of vitamin D (≤38.48 nmol/L) were independently associated with the development of PSA (OR: 2.49, 95% CI: 1.21–5.13, P = 0.01). Serum vitamin D status is related to the occurrence of anxiety in post-stroke patients and may be an independent risk factor of PSA after 1 month. PMID:27149477

    Objectives To investigate the correlation between serum level of adiponectin and severity of coronary artery atherosclerosis. Methods Coronary angiographies were performed and serum levels of adiponectin were measured in 88 patients with suspected coronary heart disease (CHD). Patients were divided into groups according to the coronary angiographies and Gensini's scores of coronary artery atherosclerosis. The serum levels of adiponectin were compared in different groups, and multiple regressions were used to analyze the correlation factors of adiponectin. Results ①Serum adiponectin concentration in CHD group [ 7.1 mg/L(2.4 ~21.1 mg/L) ] was decreased as compared with that in control group [ 11.6 mg/L(4.4 ~ 28.2 mg/L),P<0.01 ]; ②The serum levels of adiponectin fell while the Gensini' s scores of coronary artery atherosclerosis increased ( P<0.05, P<0.01 ); ③Serum level of adiponectin was positively correlated with the high-density lipoprotein cholesterol, while negatively correlated with the Gensini' s score of coronary artery atherosclerosis and triglyceride (P<0.01 ). Conclusions Serum adiponectin concentration was decreased in patients with CHD.Low serum levels of adiponectin reflected the severity of coronary artery atherosclerosis. Adiponectin was a protective factor of cardiovascular system.

    Results: The study showed an incidence of 5.0% for preterm delivery in the low risk study patients. Preterm birth was 4.83-times more common with low total maternal cholesterol than with midrange total cholesterol (11.8% versus 2.2%, P = 0.024. Conclusions: We can infer from the study that the low maternal serum cholesterol (hypocholesterolaemia is associated with preterm delivery. We can therefore recommend on this basis that the concept of an optimal range for maternal serum cholesterol during pregnancy may have merit and pregnant women should be encouraged to follow a healthy, balanced diet and ensure regular antenatal visit to their healthcare provider.

    Background It is now recognized that TSH can act on targets other than the thyroid, including the liver. Elevated serum TSH levels in euthyroid subjects were recently reported to correlate with high values of serum proprotein convertase subtilisin/kexin type 9 (PCSK9). This protein, expressed and secreted by hepatocytes, promotes higher LDL-cholesterol levels. We tested whether an acute increase of TSH levels following administration of TSH in vivo would raise PCSK9 levels in patients who had...

    To determine the role of leptin in endotoxin-induced anorexia in ruminants, circulating leptin levels were measured during acute experimental endotoxemia in sheep. Injection of bacterial lipopolysaccharide (450 ng/kg, i.v.) induced anorexia accompanied with fever and increases in serum levels of cortisol, insulin and glucose which are known to stimulate leptin secretion in rodent and human, while it did not affect serum leptin levels at all. These results indicate that serum leptin levels in sheep during acute endotoxemia are differentially regulated from those in rodent and human, and that leptin might not be involved in the endotoxin-induced anorexia in sheep.

    1983-03-01

    Three men who volunteered as normal subjects were found to have abnormally high levels of serum follicle-stimulating hormone (FSH) despite having normal seminal fluid analyses and fertility. Two of the men had a history of previous orchitis, and one had an atrophic testis. Serum luteinizing hormone and testosterone levels were normal. These cases appear to represent compensated primary testicular disease, with normal sperm counts and fertility maintained at the expense of chronically elevated FSH levels. These results imply that in certain situations, the measurement of serum FSH levels may be a more sensitive index of testicular disease than the performance of seminal fluid analyses. PMID:6402388

  1. Serum vitamin d levels and the components of metabolic syndrome: an analytical cross-sectional study

    International Nuclear Information System (INIS)

    The present study was planned to determine the serum vitamin D levels and its relation with the various components of metabolic syndrome (MetS) in MetS positive and MetS negative subjects. Methods: This analytical cross-sectional study on 88 subjects who were divided into two groups based on whether they fulfill the diagnostic criteria for MetS or not. Fasting serum glucose, lipid profile, insulin, HOMA-IR and vitamin D levels were measured. Two sample-t test and Mann-Whitney U tests were used to compare the differences. Pearson and Spearman correlation tests were used to observe the correlations. Results: BMI (p=0.001), waist/hip ratio (p=0.001), systolic blood pressure (p=0.010), diastolic blood pressure (p=0.010), fasting serum TGs (p = 0.001), TG/HDL ratio (p=0.001), fasting blood sugar (p=0.010), fasting serum insulin (p = 0.001) and HOMA-IR (p=0.001) were significantly high in MetS positive than MetS negative subjects. In MetS Positive subjects, serum vitamin D levels were found to have negative correlation with serum LDL (r= -0.485, p=0.001), total cholesterol (r= -0.408, p=0.007) and total cholesterol/HDL ratio (r= -0.355, p=0.019). Moreover, serum vitamin D levels were found to have positive correlation with HDL/LDL ratio (r= 0.443, p=0.003). Other components of MetS did not show significant correlation with serum vitamin D levels in MetS positive subjects. In MetS negative subjects, serum vitamin D levels did not show any significant correlation with any of the study parameters. Conclusions: Serum vitamin D levels were correlated with a number of MetS components which may be controlled by optimizing vitamin D levels. (author)

    The role of brain-derived neurotrophic factor (BDNF) is to promote and modulate neuronal responses across neurotransmitter systems in the brain. Therefore, abnormal BDNF signaling may be associated with the pathophysiology of schizophrenia. Low BDNF levels have been reported in brains and serums of patients with psychotic disorders. In the present study, we investigated the effects of antiepileptic drugs on BDNF in developing rats. Pregnant rats were treated with phenytoin (PHT), lamotrigine (LTG) and folic acid for long-term, all through their gestational periods. Experimental epilepsy (EE) model was applied in pregnant rats. Epileptic seizures were determined with electroencephalography. After birth, serum BDNF levels were measured in 136 newborn rats on postnatal day (PND) 21 and postnatal day 38. In postnatal day 21, serum BDNF levels of experimental epilepsy group were significantly lower compared with PHT group. This decrease is statistically significant. Serum BDNF levels increased in the group LTG. This increase compared with LTG+EE group was statistically significant. In the folic acid (FA) group, levels of serum BDNF decreased statistically significantly compared to the PHT group. On postnatal day 38, no significant differences were found among the groups for serum BDNF levels. We concluded that, the passed seizures during pregnancy adversely affect fetal brain development, lowering of serum BDNF levels. PHT use during pregnancy prevents seizure-induced injury by increasing the levels of BDNF. About the increase level of BDNF, LTG is much less effective than PHT, the positive effect of folic acid on serum BDNF levels was not observed. LTG increase in BDNF is much less effective than PHT, folic acid did not show a positive effect on serum BDNF levels. Epilepsy affects fetal brain development during gestation in pregnant rats, therefore anti-epileptic therapy should be continued during pregnancy. PMID:26706181

  3. Effect of tian meng capsule treatment on serum TGA, TMA levels in patients with hashimoto's disease

    International Nuclear Information System (INIS)

    Objective: To study the effect of tian meng capsule treatment on the serum levels of TGA, TMA in patients with chronic lymphocytic thyroiditis (CLTD or Hashimoto's disease). Methods: Serum TGA and TMA levels were determined with RIA both before and after treatment for 3 months in (1) 30 patients treated with conventional drugs (2) 30 patients treated with conventional drugs plus tian meng capsule (a traditional chinese medicine preparation No.2, tid) and (3) once in 30 controls. Results: Before treatment,the serum TGA and TMA levels in all the patients were significantly, higher than those in controls. After 3 months' treatment, serum TGA and TMA levels in all the patients dropped, but the levels in the patients treated with additional tian meng capsule were significantly lower than those in patients without tian meng capsule treatment. Moreover, 76.7% of the patients with tian meng capsule treatment had their serum TGA and TMA levels decreased over 30%, four patients even had the serum levels became normal. Conclusion: tian meng capsule treatment is very effective in lowering serum TGA and TMA levels in patients with Hashimoto's disease. (authors)

    Background Brain-derived neurotrophic factor (BDNF) is a well-established neurotrophin that plays a role in the pathophysiology of numerous psychiatric disorders. Many studies have investigated the serum BDNF levels in patients with schizophrenia. However, there are restricted data in the literature that compare the serum BDNF levels in patients with deficit and nondeficit syndromes. In this study, we aimed to compare the serum BDNF levels between schizophrenic patients with deficit or nondeficit syndrome and healthy controls. Methods After fulfilling the inclusion and exclusion criteria, 58 patients with schizophrenia and 36 healthy controls were included in the study. The patients were grouped as deficit syndrome (N=23) and nondeficit syndrome (N=35) according to the Schedule for the Deficit Syndrome. Three groups were compared in terms of the sociodemographic and clinical variants and serum BDNF levels. Results The groups were similar in terms of age, sex, body mass index, and smoking status. The serum BDNF levels in patients with deficit syndrome were significantly lower than those in healthy controls. In contrast, the serum BDNF levels in patients with nondeficit syndrome were similar to those in healthy controls. Conclusion This study suggests that decreased BDNF levels may play a role in the pathophysiology of schizophrenic patients with deficit syndrome. Nonetheless, additional studies using a larger patient sample size are needed to investigate the serum BDNF levels in schizophrenic patients with deficit syndrome. PMID:25848285

    Full Text Available Background and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients that underwent gastrostomy a blood sample was obtained minutes before the procedure. Serum and whole blood zinc was evaluated using Wavelength Dispersive X-ray Fluorescence Spectroscopy. Serum albumin and transferrin were evaluated. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC and neurological dysphagia (ND. Results: The study involved 32 patients (22 males, aged 43-88 years: HNC = 15, ND = 17. Most (30/32 had low serum zinc, 17/32 presented normal values of whole blood zinc. Only two, with traumatic brain injury, presented normal serum zinc. Serum zinc levels showed no differences between HNC and ND patients. There was no association between serum zinc and serum albumin or transferrin. There was no association between serum and whole blood zinc. Conclusions: Patients had low serum zinc when gastrostomy was performed, similar in HNC and ND, being related with prolonged fasting and unrelated with the underlying disease. Decrease serum zinc was unrelated with low serum proteins. Serum zinc was more sensitive than whole blood zinc for identifying reduced zinc intake. Teams taking care of PEG-patients should include zinc evaluation as part of the nutritional assessment, or include systematic dietary zinc supply.

    Full Text Available Mustard gas (MG, as a chemical warfare agent was used by the Iraqi army in Iran-Iraq conflict against military men in the battlefield in 1985.The serum levels of IgG, IgA and IgM of patients exposed to MG in the battlefield were measured by single radial immunodiffusion from day 3 up to one month after exposure to MG. The serum levels of IgG in patients showed significant decrease on day 3 after exposure to MG. However, the levels of IgG in the serum samples collected from the patients during 4-18 days after exposure to MG were found to increase. The increase in serum IgG levels in the sera of patients which were collected during 19-31 days after exposure to MG was found to be highly significant, surpassing those from the controls. The levels of serum IgA in patients during one month after exposure to MG showed alterations similar to those of serum IgG, however the serum alterations of the patients IgA, comparing to those of the normal controls were not significant. The serum levels of IgM in patients did not show marked alterations during one month after exposure to MG comparing to those of the normal controls. The initial decrease in serum levels of IgG in patients is discussed in terms of a possible leakage of IgG into the skin blisters and into other severely affected parts of the body such as respiratory system, whereas the subsequent increase in serum IgG is interpreted as due to (auto antigenic stimulation of the patients’ immune systems.

    The aim of the present study is to assess serum APRIL levels in SLE patients versus rheumatoid arthritis (RA) patients and normal control and to correlate serum APRIL levels in SLE patients with disease activity indices. Serum APRIL levels was measured in 40 SLE patients, 20 patients with RA and 20 healthy volunteers who served as control group. Disease activity in SLE patients was assessed by the British Isles Lupus Assessment Group (BILAG) index and SLE disease activity index (SLEDAI), and results were correlated with serum APRIL levels. Significantly higher serum APRIL levels was observed in SLE patients compared to RA patients and normal controls (p=0.003 and p < or = 0.001, respectively). Positive correlations were found between serum APRIL levels and total BILAG index (r=0.486 and p=0.001), BILAG musculoskeletal score (r=0.848 and p < or = 0.001) and BILAG cardiorespiratory score (r=0.326 and 0.04). Serum APRIL was higher in SLE patients compared to RA patients and normal control subjects and positively correlates with BILAG index and higher levels may be associated with musculoskeletal manifestations of the disease. APRIL antagonism could be a potential therapeutic target in SLE. PMID:20116334

  10. Serum leptin and soluble leptin receptor (sLR) levels in patients with breast carcinoma

    International Nuclear Information System (INIS)

    Objective: To study the changes of serum leptin and soluble leptin receptor (sLR) levels in patients with breast carcinoma. Methods: Serum leptin (with RIA) and sLR (with ELISA) levels were determined in 68 patients with breast carcinoma 31 patients with benign breast disorders, and 40 controls. BMI was also examined in these subjects. Results: Serum leptin levels in the patients were significantly higher than those in the controls (P<0.01), even after correction for the BMI differences. Serum sLR levels were significantly lower than those in the controls (P<0.05), however, after correction for BMI differences, the levels in the two groups were not much different. Levels in patients with benign breast disorders were not much different from those in controls. Conclusion: Over expression of leptin was demonstrated in patients with breast carcinoma. Leptin might promote tumor growth and could be used as a tumor marker for breast carcinoma. (authors)

    BACKGROUND: YKL-40 is a member of family 18 glycosyl hydrolases. YKL-40 is a growth factor and may stimulate migration of endothelial cells. YKL-40 may also play a role in inflammation and degradation of connective tissue. Elevated preoperative serum YKL-40 levels in patients with colorectal......, gender, and tumor location as well as the time-dependent serum YKL-40 showed that high serum YKL-40 was an independent prognostic variable of survival (HR = 8.5, 95% CI: 5.3-13.7, P < 0.0001). CONCLUSIONS: These results suggest that determination of serum YKL-40 during followup of patients operated on...

  13. The changes and significance of serum leptin levels in patients post-liver transplantation

    International Nuclear Information System (INIS)

    To explore the effect of liver transplantation-induced liver ischemia/reperfusion injury on serum leptin levels in these patients, serum samples of patients with malignant primary liver cancer or cholangiocarcinoma who had been given holo-hepatectomy were collected, and RIA and ELISA were used to detect serum levels of leptin, CRP and Interleukin-lβ (IL-1β) in these patients. Results showed that compared with self-control before operation, leptin level de- creased immediately after operation, continued to decrease after one hour of non-liver period, reached the lowest level after one hour of neo-liver period, and increased to a higher level than that of self-control before operation at ten hours after operation (P<0.05). Serum level of CRP had a similar change as that of leptin, reaching the lowest after one hour of neo-liver peri- od and recovering to normal level gradually after that. Serum level of IL-113 also expressed a trend to decrease at the beginning and to recover to normal level at 10 hours after operation. Results showed that serum leptin level decreased significantly in the early stage of post-liver transplantation and increased thereafter with a significant difference vs that before operation, which occurred concurrently with the changes of acute phase protein CRP and inflammatory cytokine IL-1β, which indicates that leptin plays an important role in liver transplantation.

    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.

  15. Serum levels of hyaluronic acid during the perioperative period of hepatic resection

    International Nuclear Information System (INIS)

    In the present study, in order to evaluate liver function during the perioperative period, serum levels of hyaluronic acid (HA) were measured. Blood samples were collected from 19 patients with hepatocellular carcinoma before hepatic resection and on the 1st, 3rd and 7th postoperative days (POD), and serum levels of HA were measured by the sandwich binding protein assay. The subjects were divided into 2 groups as follows. Group A, 14 patients, had an uneventful postoperative course, and Group B, 5 patients, had postoperative complications such as hepatic failure, liver abscess and intraperitoneal hemorrhage. The preoperative serum levels of HA had a significant correlation with the indocyanine green retention rate (ICG R15), the portal vein pressure, and the results of 99mTc-GSA scintigraphy. The preoperative serum levels of HA in the patients with clinical stage II were significantly higher than those of the patients with clinical stage I (p<0.02). The rates of the postoperative complications in the patients with preoperative HA serum levels over 100 ng/ml were significantly higher than those in the patients with HA serum levels below 50 ng/ml (p<0.05). Moreover, the postoperative serum levels of HA in Group B tended to be higher than those in Group A. On the 1st POD, there was a significant difference in the serum levels of HA between Groups A and B (p<0.01), whereas there were no significant differences in other parameters of liver function. These results suggest that serum levels of HA are useful parameters for evaluating liver function and predicting the outcome after hepatic resection. (author)

    Objective To detect the serum granulocyte colony-stimulating factor (G-CSF) levels between the patients with frequently repeated infection (repeaters) and others (non-repeaters) in different phase of infection.Methods An enzyme-linked immunosorbent assay (ELISA) method was used to detect serum G-CSF levels in 50cases (32 non-repeaters and 18 repeaters ) with acute phase of infection. Serum G-CSF levels were detected in recovery phase in 10 cases. Results Serum G-CSF levels were significantly higher ( 1429. 97 ± 506. 43ng/L) in 32 non-repeaters with acute infection. There was a positive correlation between white blood cell count (WBC) and serum G-CSF level ( r =0. 396, P <0. 05). There was also a positive correlation between absolute neutrophil count (ANC) and serum G-CSF level ( r =0. 346,P <0. 05). Serum G-CSF levels were higher (98. 62 ±56. 40ng/L ) in 18 repeaters with acute infection. It was showed that serum G-CSF levels were significantly higher in non-repeaters than in repeaters with acute phase of infection ( P <0. 001 ). In the meanwhile, the body temperature was significantly higher in non-repeaters than in repeaters with acute infection (37. 95 ±0.14℃ vs 36. 91 ±0. 13℃ , P <0. 001 ). There were no significant differences in age, WBC, ANC, type of bacterial, liver function and renal function ( P >0. 05). Serum G-CSF levels in recovery phase of the two groups were below the sensitivity of the assay ( <60 ng/L). Conclusion It is suggested that application of recombinant G-CSF may be useful for the patients with repeated infection.

    The circadian variation of serum inorganic sulfate levels was studied in healthy volunteers. The effect of subchronic acetaminophen administration (650 mg q.i.d. for 4 days) on serum inorganic sulfate levels was investigated and the possible role of fluctuating serum inorganic sulfate levels on the pharmacokinetics of acetaminophen was evaluated. During a 24 h cycle, serum inorganic sulfate levels were lowest in the morning (11.00 h) and typically increased in the afternoon to reach a maximum in the early evening (19.00 h). Average 24 h serum concentrations were 360 microM and the difference between minimum and maximum levels was on average 25.8%. Subchronic administration of acetaminophen (650 mg q.i.d. for 4 days) significantly reduced serum inorganic sulfate levels to a 24 h average of 253 microM. The circadian rhythm, however, was not affected and the difference between minimum (12.00 h) and maximum (18.50 h) serum concentrations was 31.3%. Subchronic acetaminophen administration lead to a significant decrease in the renal excretion (-51%) and renal clearance (-33%) of inorganic sulfate. No significant differences were found in the disposition kinetics of acetaminophen and its glucuronide and sulfate conjugates during two consecutive dosing intervals (08.00-14.00 h, 14.00-20.00 h) on Day 4 of the acetaminophen regimen.

    Objective: To study the clinical significance of serum neuropeptide Y level changes in patients with chronic obstructive pulmonary diseases (COPD). Methods: The serum neuropeptide Y levels were determined by radioimmunoassay in 40 patients with chronic obstructive pulmonary diseases (COPD) and 30 patients without COPD. Results: Mean serum neuropeptide Y level in patients with COPD was significantly higher than that in patients without COPD (130.36 ± 20.58 pg/ml vs 86.62 ± 13.02 pg/ml; t=10.201, p<0.01). Moreover, the levels in patients of the different stages (I, II, III) of COPD were significantly different from one another (F=20.334, p<0.01). Conclusion: the serum neuropeptide Y levels increased significantly in patients with COPD and were correlated to the different disease stages

  14. Study on the serum prolactin (PRL) level in post-menopausal women

    International Nuclear Information System (INIS)

    Objective: To explore the clinical value of determination of serum PRL levels inpost-menopausal women. Methods: Serum PRL levels were determined with RIA in 596 post-menopausal women (age 45-59, mean 55). Results: The normal range of serum PRL level in this laboratory was 0-30 ng/ml. Among the 596 women tested, 77(13%) had their PRL levels above 30 ng/ml. Further investigation with CT and/or MRI revealed presence of micro-pituitary-adenoma in 31 of the Symptoms of menopausal syndrome and osteoporosis were much more severe in women with hyperprolactinemia then in those without. Conclusion: As hyperprolactinemia might be a high risk factor for development of breast cancer, hormone replacement therapy (HRT) in menopausal women with hyperprolactinemia should be applied very cautiously, even withheld at all. Determination of serum prolactin levels in post-menopausal women is of practical clinical value. (authors)

    Full Text Available Introduction: The early detection of injury in multiple trauma patients can lead to decreased mortality, length of stay, and improved clinical status of the patient. It is shown that there is a relation between increased level of serum amylase and pancreatic injury in trauma patients. The aim of this study is to evaluate serum amylase level in hospital outcomes of patients with abdominal blunt trauma. Methods: This study was a cross-sectional survey that was conducted at the emergency room of Imam Reza (AS Medical and Educational Center in Tabriz, Iran, during a year (April 2014-April 2015 on 101 patients with blunt abdominal trauma. Serum amylase levels were measured 6 hours after injury. The outcome of patients during hospitalization including the need for laparotomy and mortality were followed. Data were analyzed by SPSS software. P < 0.050 was considered significant. Results: A significant relationship between elevated serum amylase level by laparotomy and mortality was observed (P < 0.001. 15 patients had serum amylase higher than 100 U/L. All patients with abnormal serum amylase died. Conclusion: Determination of serum amylase level can be valuable in the prognosis of patients with blunt abdominal trauma, especially in determining mortality and proceed to laparotomy. However, studies with larger research community are required to investigate the precise role of amylase in the diagnosis and prognosis of patients with blunt abdominal trauma.

    Full Text Available OBJECTIVE: Leptin is considered to be a signal factor that regulates body weight and energy expenditure, and there is a strong correlation between serum leptin concentrations, body mass index, and body fat mass in humans. Our aim in this study was to evaluate the role of leptin in valproic acid (VPA and topiramate (TPM related weight changes in epileptic patients. METHODS: Body mass index is calculated and serum leptin and insulin levels are measured in 56 patients with epilepsy (40 patients taking VPA and 16 patients taking VPA and TPM and in 40 healty control subjects. RESULTS: Obesity was seen in 21 patients (52.5% in VPA treated group, in 15 patients (37.5% in the control group and in only one male (6.3% in VPA and TPM treated group. Body mass index was lower in the group treated with VPA and TPM (p<0.001. Serum leptin concentrations were correlated with the body mass index (r=0.49, p<0.001 and were significantly higher in obese subjects (p<0.001 and in women (p<0.001. Serum leptin levels were significantly lower in patients treated with VPA and TPM (p<0.05. CONCLUSION: High levels of serum leptin in patients taking VPA and significantly low levels of serum leptin in patients taking VPA and TPM in our study are in agreement with the hypotheses that weight changes induced with VPA and TPM are related with the alterations in serum leptin levels.

    Henoch-Schönlein purpura (HSP) is a commonest systemic vasculitis (SV) in childhood characterized by an inflammatory reaction directed at vessels. Endothelial damage and perivascular leukocyte infiltrates are vital in the development of HSP. Vascular endothelial (VE)-cadherin is an endothelial cell-specific adhesion molecule, which plays critical roles in angiogenesis and endothelial integrity. Herein, we investigated the serum levels of soluble VE-cadherin (sVE-cadherin) in patients with HSP and other forms of SV. The serum levels of sVE-cadherin in 30 patients with HSP, together with patients with urticarial vasculitis, allergic vasculitis, Behcet disease, psoriasis vulgaris (PV) and atopic dermatitis (AD) and 26 health controls were measured by enzyme-linked immunosorbent assay. Serum levels of sVE-cadherin were significantly increased in patients with HSP in acute stage and patients with other forms of SV but not in patients with PV or AD. Moreover, Serum sVE-cadherin levels in HSP patients were correlated with the severity of this disease and serum concentrations of IgA anticardiolipin antibodies and vascular endothelial growth factor. Taken together, we show firstly that serum sVE-cadherin is abnormally increased in HSP patients. Increased serum levels of sVE-cadherin might be a novel biomarker for evaluating the severity of HSP and useful for identifying the presence of SV in inflammatory skin conditions. PMID:24469639

  19. Measurement of serum leptin levels in polycystic ovary syndrome with hyperandrogenemia and its significance

    International Nuclear Information System (INIS)

    Objective: To investigate the serum leptin concentration in polycystic ovary syndrome (PCOS) with hyperandrogenemia (HA) and its relationship with testosterone (T) level and body mass index (BMI). Methods: Serum leptin levels were measured by radioimmunoassay in 53 patients with PCOS, in which 36 cases were of the in non-obesity group and 17 cases in obese group. 30 non-obese cases and 20 obese cases without PCOS served as controls. Results: The levels of leptin in PCOS with HA in obese and non-obese group were significantly higher than those in control group (all p < 0.01). There was a positive correlation between serum leptin levels and testosterone levels in both groups (r = 0.51, p < 0.01 and r = 0.58, p < 0.01). No correlation existed between serum leptin levels and body mass index (BMI) in PCOS patients of non-obese group but there was positive correlation in obesity group (r = 0.56, p < 0.01). Conclusion: High serum leptin levels is one of the characteristic in PCOS patients. The HA in PCOS patients is related to serum leptin levels and heavyweight or obese patients have the phenomenon of leptin resistance

    Full Text Available Abstract Background The association between low serum testosterone levels, visceral adipose tissue (VAT, and metabolic syndrome is now well known. However, the relationship between hepatic steatosis and serum testosterone levels has not been extensively studied. Our aim was to investigate the association of serum total testosterone levels with nonalcoholic fatty liver disease (NAFLD, adjusting for the influence of VAT and insulin resistance. Methods This study is a retrospective observational cross-sectional one of healthy Korean men and was conducted at the Seoul National University Hospital Healthcare System Gangnam Center. We used data obtained from 495 men who were at least 20 years of age and who had undergone blood testing, abdominal computed tomography, and ultrasonography. Multiple logistic regression analysis was used to explore the association of serum total testosterone levels with NAFLD. Results Men in the low serum testosterone quintile were at a higher risk for NAFLD than men in the highest serum testosterone quintile. After adjusting for age, smoking, diabetes, exercise, BMI, triglycerides, and high-density-lipoprotein cholesterol, subjects with serum testosterone levels in the lowest quintile had an odds ratio (OR (95% confidence interval (CI of 5.12 (2.43–10.77 for NAFLD (p value, 0.0004. The inverse association between serum testosterone and NAFLD was attenuated by further adjustment for variables including VAT; however, it remained statistically significant (OR (95% CI: 4.52 (2.09–9.80 in the lowest quintile; p value=0.004. Conclusions A low serum total testosterone level was independently associated with NAFLD. This report is the first one suggesting the association remains unchanged even after controlling for VAT and insulin resistance.

  9. Detection of serum leptin levels in patients with viral hepatitis and fatty liver

    International Nuclear Information System (INIS)

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

    Brominated flame retardants (BFRs) is a group of environmental chemicals for which lately both interest and knowledge have increased considerably. Among the BFRs, the polybrominated diphenyl ethers (PBDEs) have attained special interest. Much data on environmental and human levels have been presented and several toxicological reviews are now published. Among interesting results is the difference in human PBDE levels that seem to exist between U.S.A. and Europe, results that suggest differences in exposure but without being able to pin-point the exact sources. In experimental studies PBDEs alter serum thyroxin levels, an effect seen both in rats and in mice. The mechanism(s) are still not completely clarified, but are thought to include alterations in serum transport, induced enzymatic degradation and possibly also direct effects on the thyroid gland. As perinatal alterations in thyroid homeostasis could affect brain development, early effects on thyroid hormones may be of special concern. Indeed, PBDEs have been shown to affect behaviour and learning in mice, when given neonatally. The aim of the present study was to relate the serum levels of PBDEs in rats to effects of these compounds on thyroxine homeostasis in these animals. Specifically, the relation between serum PBDE levels and effects on serum thyroxine levels was investigated, after two weeks of daily oral exposure. The result may have consequences for the future risk assessment activities on PBDE and specifically in finding the critical serum PBDE concentration at which the effect on thyroid hormone levels begin to occur.

    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.

  12. Changes of serum leptin, adiponection and insulin levels in females with simple obesity

    International Nuclear Information System (INIS)

    Objective: To study the changes of serum leptin, insulin and adiponectin levels and their relationship with BMI in females with simple obesity. Methods: Serum leptin, adiponectin and insulin levels were measured with RIA in 48 pre-obese females (BMI=23-24.9 kg/m2), 40 females with simple obesity, (BMI≥25 kg/m2) and 42 female controls (BMI 18-22.9 kg/m2). Correlations among these variables were studied. Results: Serum leptin, insulin levels were significantly higher and serum adiponectin levels were significantly lower in both the pre-obese and obese females than those in controls. Serum leptin, insulin levels were positively correlated to BMI; Serum adiponectin levels were negatively correlated to BMI. Conclusion: Within normal range of BMI, the leptin-insulin feedback mechanism provided satisfactory self-regulation. However, with excessive BMI, this dynamic equilibrium would be disrupted. The defective equilibrium, together with the abnormal low adiponectin level, would predispose to the development of diabetes mellitus. (authors)

    Full Text Available Objective: P-selectin is an adhesion molecule expressed by activated endothelial cells and platelets favouring the leukocyte adherence to microvascular endothelium. A soluble form of this molecule has been described, whose serum levels were found to be elevated and correlate with disease activity in rheumatoid arthritis (RA patients. Aim of this study was to determine soluble P-selectin levels in synovial fluid (SF and serum from patients with psoriatic arthritis (PsA, where it has never been investigated, to define its involvement in PsA synovial damage. Methods: we analysed, by ELISA, soluble P-selectin serum and SF levels in 100 patients presenting a knee joint effusion: 38 of them presented PsA, 40 RA and 22 osteoarthritis (OA. We examined the main clinical and laboratory parameters of these patients. Soluble P-selectin serum levels were also detected in 15 healthy subjects. Results: soluble P-selectin SF levels were significantly higher in PsA and RA patients respect to OA subjects. Soluble P-selectin SF levels were lower than those found in serum and the SF/serum ratio was higher in PsA and RA patients respect to OA. Soluble P-selectin serum levels were not significantly different among patients and controls. No correlation was found between SF and serum levels of soluble P-selectin and the main clinical parameters. Conclusions: our study of soluble P-selectin in PsA reveals a prominent local role of this molecule, with no differences respect to RA. Histological findings may be of help in understanding the role of this adhesion molecule in PsA.

    Full Text Available Abstract Background Both C reactive protein (CRP and procalcitonin (PCT are well known acute phase reactant proteins. CRP was reported to increase in metabolic syndrome and type-2 diabetes. Similarly altered level of serum PCT was found in chronic liver diseases and cirrhosis. The liver is considered the main source of CRP and a source of PCT, however, the serum PCT and CRP levels in non-alcoholic fatty liver disease (NAFLD were not compared previously. Therefore we aimed to study the diagnostic and discriminative role of serum PCT and CRP in NAFLD. Methods Fifty NAFLD cases and 50 healthy controls were included to the study. Liver function tests were measured, body mass index was calculated, and insulin resistance was determined by using a homeostasis model assessment (HOMA-IR. Ultrasound evaluation was performed for each subject. Serum CRP was measured with nephalometric method. Serum PCT was measured with Kryptor based system. Results Serum PCT levels were similar in steatohepatitis (n 20 and simple steatosis (n 27 patients, and were not different than the control group (0.06 ± 0.01, 0.04 ± 0.01 versus 0.06 ± 0.01 ng/ml respectively. Serum CRP levels were significantly higher in simple steatosis, and steatohepatitis groups compared to healthy controls (7.5 ± 1.6 and 5.2 ± 2.5 versus 2.9 ± 0.5 mg/dl respectively p Conclusion Serum PCT was within normal ranges in patients with simple steatosis or steatohepatitis and has no diagnostic value. Serum CRP level was increased in NAFLD compared to controls. CRP can be used as an additional marker for diagnosis of NAFLD but it has no value in discrimination of steatohepatitis from simple steatosis.

    Full Text Available Both uremia and HD process cause immunosuppression in HD patients. There was significant increase of total serum IgG and IgM levels found in patients with chronic HCV compared with healthy controls. There is evidence pointing to direct effect of rHuEPO upon B cells. High doses of recombinant human erythropoietin (rHu EPO enhanced in vitro Ig production and proliferation of various plasma cell lines, as well as human plasma cells generated in vitro. Study was conducted at hemodialysis Unit of Shubra Municipal hospital between August 2010 to February 2011. 30 HCV positive patients on regular hemodialysis were included in study, using bicarbonate dialysate and polysulfone membrane dialyser, for 4 hours 3 times weekly. Patients were divided into 2 groups: first group: 15 patients on EPO therapy. 4000 IU/week and second group not taking EPO for all patients full clinical examination was done, CBC, BUN, serum creatinine, ALT, AST, serum albumin and serum IgM by ELISA (quantitative assay, were done. There was no significant difference between 2 groups as regards age, sex distribution, WBC count, ALT, AST, serum creatinine, BUN and IgM serum level. First group had borderline significant higher Hgb and Hct than second group (p = 0.056. Females didn't have higher serum IgM level than males (p = 0.403. All correlations of IgM serum level to other parameters of study were irrelevant. Uremia seems to protect ESRD patients on regular HD from complications of HCV and also EPO effect on Ig serum levels.

    Full Text Available Background: Diabetes is a major health problem worldwide. Type II diabetic patients are reported to have higher ferritin and lower vitamin C concentrations. Considering the role of ascorbic acid in carnitine biosynthesis and the limited information on free carnitine correlations with ferritin and vitamin C levels in diabetic patients without microvascular complications, this case-control study was conducted to determine ferritin and vitamin C levels in hyperlipidemic-diabetic men comparing to healthy controls; the correlation of free carnitine with ferritin and vitamin C levels were also studied in these patients.Methods: Thirty-five hyperlipidemic-diabetic and seventy healthy men, were included in the study by the convenience sampling method. Body Mass Index, blood pressure, fasting blood glucose, lipid profile, ferritin and vitamin C levels were assessed in both case and control groups; moreover, serum free carnitine was measured in both groups. Dietary assessments were performed using 24 hour recall and food frequency questionnaires.Results: Blood pressure, fasting blood glucose, cholesterol, triglyceride, LDL, and HDL concentrations were significantly higher in the case group. Mean serum ferritin concentrations were higher in diabetics comparing to controls (93.22±0.27 vs. 44.66±4.23 µg/l; whereas, mean plasma vitamin C in these patients were lower than the healthy subjects (0.68±0.07 vs. 0.89±0.05. Positive correlations were observed between free carnitine and vitamin C levels.Conclusion: According to the results, it could be suggested that vitamin C supplementation in diabetic patients with hyperlipidemia might be useful. In addition, inclusion of serum ferritin assay in routine evaluation of diabetic patients could be beneficial.

    Full Text Available Objective: Febrile convulsion is the most common disorder in childhood with good prognosis. There are different hypotheses about neurotransmitters and trace element (such as zinc changes in cerebrospinal fluid and serum, which can have a role in pathogenesis of febrile convulsion. The aim of the present prospective analytical case-control study was to determine whether there was any changes in serum zinc level in children with febrile convulsion during seizure.Methods: Ninety-two children aged 6 months to 5 years were divided into three groups: group A, 34 children with febrile convulsion, group B, 40 children having fever without convulsion, and group C, and 18 children with non-febrile convulsion. Serum zinc levels for the three groups were estimated by atomic absorption spectrophotometry (AAS. Data were analyzed to compare zinc level among the three groups using appropriate statistical tools employing SPSS 13.Findings: Serum zinc levels of groups A, B, and C had a mean value of 76.82±24.36mg/1, 90.12±14.63 mg/1 and 94.53±17.39 mg/l, respectively. Serum zinc level of group A was lower than those of the other two groups (P<0.006. It was also lower in group B than in group C (P<0.006.Conclusion: These findings revealed that serum zinc level decreases during infection; this decrease was more significant in patients with febrile convulsion.

    International Nuclear Information System (INIS)

    To measure serum leptin levels and compare them in lean and obese subjects and to identify correlation between serum leptin levels, heart rate and hypertension in lean and obese subjects among adult females. Seventy female subjects with different body mass indices were selected from OPD of Jinnah Medical and Dental College Hospital (OPD), Karachi. Heart rate was counted manually; blood pressure was measured by mercury sphygmomanometer while serum leptin was measured using enzyme-linked immunoassay. The outcomes hypertension and heart rate were correlated to risk factor leptin. Mean heart rate, systolic and diastolic blood pressure and serum leptin levels of obese people were 90+-1, 142+-2, 89+-1 and 24.13+-1.7 respectively, which were significantly higher as compared to lean subjects (p<0.05). All the parameters correlated positively and significantly with increasing BMI. There was a relationship of tachycardia and hypertension with high serum leptin levels in obesity. Serum leptin levels increase with the level of obesity. Hyper-leptinemia is associated with tachycardia and increases in both systolic and diastolic blood pressure in obesity via complex mechanisms.

    Recently, hepcidin, an antimicrobial-like peptide hormone, has evolved as the master regulator of iron homeostasis. Despite the growing evidence of iron imbalance in childhood-onset ischemic stroke, serum hepcidin level in those patients has not yet been researched.In this study, we aimed to estimate serum (hepcidin) level in acute ischemic stroke (AIS) patients and to investigate whether subcutaneous enoxaparin sodium, which is a low-molecular-weight heparin (LMWH) derivative, could modulate serum hepcidin level in those patients.This was a case-control study included 60 (AIS) cases, and 100 healthy children with comparable age and gender as control group. For all subjects' serum hepcidin, interleukin-6 (IL-6), and soluble transferrin receptor [sTfR]) levels were assessed by (enzyme-linked immunosorbent assay [ELISA] method). Iron parameters including (serum iron, ferritin, transferrin, and total iron binding capacity [TIBC]) were also measured. The patients were subdivided according to treatment with an LMWH derivative into 2 groups and serum hepcidin levels were assessed initially and 1 week after stroke onset for all cases.We found that AIS cases had higher serum iron, ferritin, and IL6 levels compared to the control group (all P  0.05). However, on the 7th day of diagnosis serum hepcidin level decreased significantly in AIS cases treated with LMWH (group 1) (median, 36 vs 21 ng/mL; P  0.05). Serum hepcidin showed significant positive correlations with serum iron, transferrin saturation, ferritin, and IL6 (r = 0.375, P < 0.05; r = 0.453, P < 0.05; r = 0.687, P < 0.01; r = 0.515, P < 0.01; respectively).Our data brought a novel observation of elevated serum hepcidin level in pediatric AIS patients and pointed out that treatment with LMWH could modulate hepcidin level in those patients.

    Full Text Available BACKGROUND Thyroid disorders are common endocrine disorders. Thyroid function tests which are usually done are measurement of blood levels of hormones Triiodothyronine (T3, Thyroxine (T4 and Thyroid Stimulating Hormone (TSH, which are affected by various nonspecific conditions. Therefore, the present study is done to evaluate the role of additional biochemical parameter Creatine Kinase (CK in diagnosing hypothyroidism. Thyroid function and Creatine Kinase activity was measured in 70 patients with clinically suspected cases of hypothyroidism. Patients with hypothyroidism will have decreased T3, T4 levels and increased levels of TSH. However, whether there is any correlation of Creatine Kinase with hypothyroidism is not well established. In our study, we found that in hypothyroid patients there is significant increase in CK levels. Measurement of CK levels is an additional biochemical parameter to diagnose hypothyroidism

    Full Text Available Background. Alzheimer's disease (AD is the most common cause of dementia in the elderly. AD is characterized by the accumulation of amyloid plaques and neurofibrillary tangles and by massive neuronal loss in the brain. There is epidemiologic and pathologic evidence that AD is associated with vascular risk factors and vascular diseases, contributing to cerebral hypoperfusion with consecutive stimulation of angiogenesis and upregulation of proangiogenic factors such as Angiopoietin-1 (Ang-1. Methods. In the present study, we measured Ang-1 serum levels in 42 patients with AD, 20 patients with mild cognitive impairment (MCI, and in 40 healthy elderly controls by ELISA. Results. We found significantly increased Ang-1 serum levels in patients with AD compared to control subjects (P=0.003. There was no significant difference between MCI patients and healthy controls (P=0.553 or between AD and MCI patients (P=0.054. The degree of cognitive impairment as measured by the mini-mental status examination (MMSE score was significantly correlated with the Ang-1 serum levels in all patients and healthy controls. Conclusions. We found significantly increased Ang-1 serum levels in AD patients. We could also show an association between Ang-1 serum levels and the cognitive status in all patients and healthy controls. Thus, serum Ang-1 could be a potential candidate for a biomarker panel for AD diagnosis.

In 146 peri and postmenopausal women, the serum level of estradiol was from 3 to 6pg/ml. The serum level of estradiol in 38 women after HRT significantly increased (p < 0.01) from 3.34 to 23.6 pg/ml at 6 months, and 21.5 pg/ml at 12 months. The serum level of estrone significantly increased (p < 0.01) from 26.6pg/ml to 156.7pg/ml at 6 months, and 137.2pg/ml at 12 month. These results are very useful for deciding on the doses of hormones and the expected serum estradiol level in HRT for Japanese women. PMID:7636337

    The purpose of this study is to gain understanding of the relationship between ejaculation and serum testosterone level in men. The serum testosterone concentrations of 28 volunteers were investigated daily during abstinence periods after ejaculation for two phases. The authors found that the fluctuations of testosterone levels from the 2nd to 5th day of abstinence were minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, reaching 145.7% of the baseline (P<0.01). No regular fluctuation was observed following continuous abstinence after the peak. Ejaculation is the precondition and beginning of the special periodic serum testosterone level variations, which would not occur without ejaculation. The results showed that ejaculation-caused variations were characterized by a peak on the 7th day of abstinence; and that the effective time of an ejaculation is 7 days minimum. These data are the first to document the phenomenon of the periodic change in serum testosterone level; the correlation between ejaculation and periodic change in the serum testosterone level, and the pattern and characteristics of the periodic change.

    Full Text Available Breast cancer is the most common site specific cancer in women. Lots of etiological factors have been suggested regarding its causation. The risk is influenced by obesity, parity, exogenous and endogenous hormones, exposure to chemicals and radiation and many more. Various studies suggest that as HDL-C seems to be cardio protective, it is also protective for breast cancer. Serum HDL-C levels are found to be low in breast cancer patients. We studied this hypothesis in local population of Southern Rajasthan and nearby region to see if low serum HDL-C is associated with increased risk of breast cancer. We studied serum HDL-C level in 50 female patients of breast cancer along with their menopausal status and compared it to their respective controls. We found that breast cancer patients had significantly low level of serum HDL-C and presented in advanced stage of cancer. It supports that low serum HDL-C level is associated with increased risk of breast cancer. So one should think about those dietary and lifestyle measures, which maintain high serum HDL-C level so that it might become preventive measure for breast cancer.

    Full Text Available Background: Protein carbonyl (P is oxidatively-modified protein with diagnostic potential for acute myocardial infarction. However, many findings indicated the elevation of serum PC content level related to exercise, which could cause false positive results and limiting the specificity for acute coronary syndrome diagnosis. This study aims to evaluate the level of serum protein carbonyl content in healthy volunteers subjected to exercise stress test (EST. Materials and Methods: Serum from healthy volunteers was collected 5-10 min before performing EST and 1 hour after the EST was achieved. The serum was collected, and the serum PC content level was determined by spectrophotometric DNPH assay. Results: The serum PC content level after exercise stress test was significantly higher than that of before performing EST (0.373 ± 0.05 nM/mg vs. 0.275 ± 0.02 nM/mg, P < 0.0001. The results demonstrated that in both male and female, serum PC content level after EST was significantly higher than that of before performing EST (0.29 ± 0.03 nM/mg vs. 0.36 ± 0.05 nM/mg P < 0.0001 in male, 0.27 ± 0.02 nM/mg vs. 0.38 ± 0.06 nM/mg P < 0.0001 in female, respectively. Conclusions: This study demonstrated that exercise stress test could result in non-specificity and false positive increasing in serum PC content level in healthy subjects, which may cause misinterpretation when using PC as cardiac marker, especially in patients, who underwent exercise stress test or patients who performing heavy physical activities.

    Background Fatty acid-binding protein 4 (FABP4/A-FABP/aP2) is secreted from adipocytes in association with catecholamine-induced lipolysis, and elevated serum FABP4 level is associated with obesity, insulin resistance and atherosclerosis. Secreted FABP4 as a novel adipokine leads to insulin resistance via increased hepatic glucose production (HGP). Sodium-glucose cotransporter 2 (SGLT2) inhibitors decrease blood glucose level via increased urinary glucose excretion, though HGP is enhanced. Here we investigated whether canagliflozin, an SGLT2 inhibitor, modulates serum FABP4 level. Methods Canagliflozin (100 mg/day) was administered to type 2 diabetic patients (n = 39) for 12 weeks. Serum FABP4 level was measured before and after treatment. Results At baseline, serum FABP4 level was correlated with adiposity, renal dysfunction and noradrenaline level. Treatment with canagliflozin significantly decreased adiposity and levels of fasting glucose and HbA1c but increased average serum FABP4 level by 10.3% (18.0 ± 1.0 vs. 19.8 ± 1.2 ng/ml, P = 0.008), though elevation of FABP4 level after treatment was observed in 26 (66.7%) out of 39 patients. Change in FABP4 level was positively correlated with change in levels of fasting glucose (r = 0.329, P = 0.044), HbA1c (r = 0.329, P = 0.044) and noradrenaline (r = 0.329, P = 0.041) but was not significantly correlated with change in adiposity or other variables. Conclusions Canagliflozin paradoxically increases serum FABP4 level in some diabetic patients despite amelioration of glucose metabolism and adiposity reduction, possibly via induction of catecholamine-induced lipolysis in adipocytes. Increased FABP4 level by canagliflozin may undermine the improvement of glucose metabolism and might be a possible mechanism of increased HGP by inhibition of SGLT2.

    Resistin is a novel adipocyte-secreted hormone that has been proposed to be the link between obesity and diabetes, although little appears to be known regarding the physiological role of resistin in human beings. We aimed to explore the relationship between serum resistin level and certain anthropometric and metabolic parameters. Seventy-one healthy subjects with a mean body mass index of 23 kg/m 2 or greater were recruited in this study. Anthropometric measurements including height, weight, body mass index, waist and hip circumferences, waist-to-hip ratio, and blood pressure were recorded. Insulin resistance was measured by homeostasis model assessment (HOMA). Fasting serum resistin, insulin and plasma glucose, lipid profiles, and uric acid levels were measured. The results revealed that serum resistin level did not correlate with any markers for adiposity, blood pressure, fasting plasma glucose, or uric acid level for either sex. Serum resistin level correlated negatively with fasting insulin level (gamma=-0.455, P=.006) and HOMA (gamma=-0.455, P=.006) in women but not in men. Serum resistin level only correlated negatively with high-density lipoprotein cholesterol (HDL-C) level in men (gamma=-0.347, P=.038); there was no correlation between serum resistin level and lipid profiles in women. Multiple linear regression analysis using the logarithm of resistin as a dependent variable revealed that only HDL-C level (beta=-.058, P=.019) was an independent significant predictor for resistin in men; however, the analysis revealed that HDL-C level (beta=-.044, P=.029) and HOMA (beta=-.719, P=.004) were independent significant predictors for resistin in women. In conclusion, resistin is not related to adiposity, blood pressure, insulin resistance, fasting plasma glucose level, and most lipid profiles. Resistin correlates negatively with HDL-C level for both sexes. The role of resistin in metabolic syndrome warrants further investigation. PMID:15798953

    Full Text Available Background. Survivin is an inhibitor of apoptosis protein involved in the regulation of cell proliferation that could be used as a marker for cancer diagnosis or prognosis. Our aim was to evaluate whether serum survivin levels influence the outcome of cisplatin-based chemotherapy in patients with malignant mesothelioma (MM. Methods. Serum survivin levels were determined using human survivin enzyme-linked immunosorbent assay in 78 MM patients before chemotherapy, after chemotherapy, and at disease progression. The influence on tumor response and survival was evaluated using nonparametric tests and Cox regression. Results. A median serum survivin level at diagnosis was 4.1 (0–217.5 pg/mL. Patients with a progressive disease had significantly higher survivin levels before chemotherapy (p = 0.041. A median serum survivin level after chemotherapy was 73.1 (0–346.2 pg/mL. If survivin levels increased after chemotherapy, patients had, conversely, better response (p = 0.001, OR = 5.40, 95% CI = 1.98–14.72. Unexpectedly, patients with increased survivin levels after chemotherapy also had longer progression-free (p < 0.001, HR = 0.33, 95% CI = 0.20–0.57 and overall survival (p = 0.001, HR = 0.29, 95% CI = 0.14–0.58. Conclusions. These results suggest that serum survivin levels before and during chemotherapy could serve as a biomarker predicting MM treatment response.

  10. Changes in Serum Levels of Myokines and Wnt-Antagonists after an Ultramarathon Race.

    Katharina Kerschan-Schindl

    Full Text Available Regular physical activities have a positive effect on the muscular skeletal system but overstrenuous exercise may be different. Transiently suppressed bone formation and increased bone resorption after participation in a 246-km ultradistance race has been demonstrated.The aim of this study was to analyze effects of the Spartathlon race on novel musculoskeletal markers.Venous blood samples were obtained before and immediately after the race from 19 participants of the Spartathlon. From 9 runners who were available 3 days after the start blood was drawn for a third time. Serum levels of myostatin, an inhibitor of myogenic differentiation, and its opponent follistatin as well as sclerostin and dickkopf-1, both of them inhibitors of the wnt signaling pathway, and markers of bone turnover were determined.Serum levels of myostatin were significantly higher after the race. Serum follistatin only showed a transient increase. Sclerostin levels did not significantly differ before and after the race, whereas dickkopf-1 levels were significantly decreased. At follow-up a decrement of sclerostin and dickkopf-1 levels was seen. Serum cathepsin K levels did not change.The increase of serum levels of myostatin appears to reflect muscle catabolic processes induced by overstrenuous exercise. After the short-term uncoupling of bone turnover participation in an ultradistance race seems to initiate a long-term positive effect on bone indicated by the low-level inhibition of the Wnt/β-catenin signaling pathway.

    Full Text Available The purpose of this study was to estimate black/white differences in cotinine levels for current smokers of both sexes, and to explore the potential contribution of mentholated cigarettes to these differences. Sera from 255 current smokers sampled from Southern Community Cohort Study participants (65 black men, 65 black women, 63 white men, 62 white women were analyzed for cotinine, and linear regression was used to model the effect of race on cotinine level, adjusting for the number of cigarettes smoked within the last 24 hours, use of menthol vs. non-menthol cigarettes, exposure to environmental tobacco smoke, and age. Black smokers smoked fewer cigarettes than white smokers, yet had crude mean cotinine levels nearly as high or higher than white smokers. After multivariate adjustment, cotinine levels were an average of 50 ng/ml higher among black than white women (p=0.008 and non-significantly 12 ng/ml higher among black than white men (p=0.52. We observed no increase in cotinine levels associated with menthol cigarette use. We conclude that differences in cotinine levels among smokers suggest racial variation in exposure to and/or metabolism of tobacco smoke constituents, but our findings do not support a role for menthol preference in this disparity.

  12. Evaluation of Serum Testosterone and Estradiol Levels in Positive Hepatitis C Virus in Liver Insufficiency Patients

    International Nuclear Information System (INIS)

    Twenty-two positive HCV male patients with liver insufficiency were classified into 4 different groups: steatohepatitis (16), chronic hepatitis (17), cirrhosis (12) and HCC (7), beside 24 healthy subjects served as control to evaluate serum sex hormones testosterone and estradiol, and trace elements Zn and Cu in different liver insufficiency positive male HCV patients. The results of the present study showed significant decrease (P<0.05 and P<0.001) in serum testosterone level and testosterone/estradiol ratio in patients with different liver states when compared with control. The serum testosterone level was significantly decreased (P<0.05 and P<0.001)) in patients with cirrhosis than other patient groups. On the other hand, there was significant increase (P<0.01 and P<0.001) in serum estradiol level in all groups as compared with control. Serum testosterone/estradiol ratio was less affected and significantly increased (P<0.01 and P<0.001) in patients with steatohepatitis than other patient groups. Also, the results showed significant decrease (P<0.001) in serum Zn level in patients when compared with control and significant decrease (P<0.05) in cirrhosis as compared with HCC. Also, significant increase (P<0.01 and P<0.001) was determined in serum Cu level and Cu/Zn ratio in different groups as compared with control group. Serum Cu level was significantly decreased (P<0.05) in chronic hepatitis as compared with cirrhosis and HCC. On the other hand, serum Cu/Zn ratio was significantly increased in cirrhosis as compared with steatohepatitis and chronic hepatitis groups (P<0.05 and P<0.01). The patient groups can be detected by using either zinc, copper, testosterone or estradiol contents in serum. It could be concluded that the levels of serum sex hormones (testosterone and estradiol) and trace elements (Zn and Cu and their ratio) may used as markers for liver insufficiency and liver complications, especially in the early diagnosis and prediction of HCC in patients

    Full Text Available C-reactive protein (CRP has previously been shown to serve as a prognostic parameter in women with gynecologic malignancies. Due to the lack of valid prognostic markers for uterine leiomyosarcoma (ULMS this study set out to investigate the value of pre-treatment CRP serum levels as prognostic parameter.Data of women with ULMS were extracted from databases of three Austrian centres for gynaecologic oncology. Pre-treatment CRP serum levels were measured and correlated with clinico-pathological parameters. Univariate and multivariable survival analyses were performed.In total, 53 patients with ULMS were included into the analysis. Mean (SD CRP serum level was 3.46 mg/dL (3.96. Solely, an association between pre-treatment CRP serum levels and tumor size (p = 0.04 but no other clinic-pathologic parameter such as tumor stage (p = 0.16, or histological grade (p = 0.07, was observed. Univariate and multivariable survival analyses revealed that CRP serum levels (HR 2.7 [1.1-7.2], p = 0.037 and tumor stage (HR 6.1 [1.9-19.5], p = 0.002 were the only independent prognostic factors for overall survival (OS in patients with ULMS. Patients with high pre-treatment CRP serum levels showed impaired OS compared to women with low levels (5-year-OS rates: 22.6% and 52.3%, p = 0.007.High pre-treatment CRP serum levels were independently associated with impaired prognosis in women with ULMS and might serve as a prognostic parameter in these patients.

    Full Text Available Objective: The aim of this study was to evaluate the serum level of interleukin-17 (IL-17 and IL-35 in thyroid cancer patients and its diagnostic value as a biomarker. Methods: Sixty-one thyroid carcinoma patients were recruited from January 2012 to December 2014 in our hospital. Of the 61 included cases, 42 subjects were pathology confirmed with thyroid cancer and other 19 cases were diagnosed with thyroid adenoma. The serum level of IL-17 and IL-35 were compared between the two groups. The diagnosed sensitivity, specificity, and receiver operating characteristic curve (ROC for serum IL-17 and IL-35 were evaluated according to Bayes theorem. Results: The serum level of IL-17 were 16.3 ± 4.1 pg/ml and 9.4 ± 3.6 pg/ml for the thyroid cancer and thyroid adenoma patients respectively, with statistical difference (P < 0.05. The serum level of IL-35 were 48.8 ± 7.8 pg/ml and 62.3 ± 9.6 pg/ml for the thyroid cancer and thyroid adenoma patients, respectively, which indicated that the thyroid adenoma group was much higher with statistical difference (P < 0.05. The diagnosis sensitivity and specificity for serum IL-17 were 71.4% and 80.2% at the cutoff value of 12.1 pg/ml with the area under the ROC of 0.8239. The diagnosis sensitivity and specificity for serum IL-35 were 76.8% and 82.4% at the cutoff value of 57.6 pg/ml with the area under the ROC of 0.8722. Conclusion: The serum level of IL-17 and IL-35 was significantly different between thyroid cancer and thyroid adenoma patients, which could be a potential biomarker for the diagnosis of malignant thyroid tumor.

    Full Text Available Objectives. The aim of our study was to examine serum anti-Müllerian hormone (AMH concentration in ovarian cancer patients in relation to clinicopathological features, such as a pathological subtype of the tumor, (FIGO stage, grading, and overall 5-year survival. Material and Methods. We enrolled 72 epithelial ovarian cancer patients in our study, aged 45–79 years, who underwent optimal cytoreductive surgery. In all patients, serum AMH concentration was measured using a two-step sandwich type enzyme immunoassay before surgery. As a reference value for women over 45 years we accepted anti-Müllerian hormone concentration below 1 ng/mL. Results. In the whole group of patients with ovarian cancer, median serum concentration of AMH was 0.07 (0.0–0.37 ng/mL, whereas in the group of those with positive AMH values (≥0.14 ng/mL it was 0.31 (0.15–0.73 ng/mL. No significant correlation was found between serum AMH levels and FIGO stage, histological subtype, or grading (. The analysis of five-year survival rate related to AMH levels showed no statistically significant differences. There were no differences in survival rates between patients with positive or negative serum AMH levels. Conclusion. Measurement of serum anti-Müllerian hormone levels was not useful in predicting clinicopathological features and survival in patients with ovarian cancer.

    Full Text Available Aim. While there are many well-defined serological markers for inflammatory bowel disease (IBD, there is limited evidence that they positively affect clinical outcomes. This study aimed to evaluate the correlation between hepcidin serum levels and disease activity in IBD. Materials and Methods. Eighty-five consecutive IBD patients were enrolled in the study. Hepcidin serum levels were assessed using an enzyme-linked immunosorbent assay (ELISA and were compared with disease activity as well as the interleukin-6 (IL-6 and C-reactive protein (CRP levels. Results. The mean hepcidin serum levels in Crohn’s disease (CD patients in remission and in the active phase were 3837±1436 and 3752±1274 pg/mL, respectively P=0.613. The mean hepcidin serum levels in ulcerative colitis (UC patients in remission and in the active phase were 4285±8623 and 3727±1176 pg/mL, respectively P=0.241. Correlation analysis between inflammatory markers and hepcidin serum levels indicated that there was no correlation between hepcidin levels and IL-6 P=0.582 or CRP P=0.783. Conclusion. As an acute-phase protein, hepcidin seems to have a lower efficacy than other parameters in the detection of activation in IBD.

    1996-01-01

    Full Text Available The aim of the present study was to compare, during the pollen season, serum levels of total IgE and soluble CD23 (sCD23 from patients with allergic bronchial asthma, with those from healthy subjects. Significantly higher levels of total IgE and sCD23 were found in patients with asthma compared to the control group. Both in normal controls and in asthmatic patients, a significant correlation was shown between the levels of these two molecules. In asthmatic patients, significant correlations were found for both total IgE and sCD23, with lung function measured as bronchial responsiveness to inhaled methacholine. These results suggest that in asthmatic patients, in addition to the study of total serum IgE levels, the assessment of sCD23 serum levels may be helpful in the evaluation of disease activity.

    Objective: To study the clinical significance of changes of serum levels of gastrin in patients with chronic eczema or chronic urticaria. Methods: Serum gastrin levels were, 37 patients with chromic urticaria and 43 controls. Results: Serum gastrin levels in patients with chronic exzema (102.95 ± 27.33 ng/L) and patients with chronic urticaria (109.87 ± 33.64 ng/L) were both significantly higher than those in controls (61.72 ± 20.38 ng/L, both P<0.01). Difference between the levels in the two patients groups was not significant. Conclusion: The high gastrin levels in those patients might reflect the presence of helicobacter pylori infections; eradication of which might be helpful for treatment of these chronic dermatologic disorders.

    Soluble interleukin 2 receptors (IL-2R) in sera of leprosy patients from Chiang Mai, Thailand, were quantified with a solid phase enzyme immunoassay using two monoclonal antibodies to the IL-2R. The IL-2R levels of untreated lepromatous, borderline lepromatous or midborderline patients and treated lepromatous and borderline lepromatous or treated borderline tuberculoid and tuberculoid patients were comparable to those of the Thai household or nonhousehold contacts; and they were significantly higher than the levels of USA control subjects. In contrast, IL-2R of untreated tuberculoid or borderline tuberculoid patients were significantly reduced. Patients with ongoing reversal reaction had very high circulating IL-2R, the levels of which correlated with fever and extent of skin lesions. Although erythrema nodosum leprosum patients also had elevated IL-2R levels, they were significantly below those of patients with reversal reaction. When treated with corticosteroid, precipitous reduction of IL-2R was noted in all patients with reversal reaction but not in patients with erythema nodosum leprosum. PMID:3115652

    Oxidative stress increases serum thioredoxin (TRX), a redox-regulating protein with antioxidant activity recognized as an oxidative stress marker. The aim of this study was to assess the clinical significance of serum TRX levels in Chinese patients with acute ischemic stroke (AIS). From January 1, 2012, to December 31, 2013, all patients with first-ever acute ischemic stroke were recruited to participate in the study. Serum levels of TRX were assayed with solid-phase sandwich enzyme-linked immunosorbent assay (ELISA), and the severity of stroke was evaluated with the National Institutes of Health Stroke Scale (NIHSS) score on admission. The results indicated that the median serum TRX levels were significantly (P operating characteristic (ROC) curve, the optimal cutoff value of serum TRX levels as an indicator for auxiliary diagnosis of AIS was projected to be 11.0 ng/mL, which yielded a sensitivity of 80.3 % and a specificity of 73.7 %, with the area under the curve at 0.807 (95 % CI, 0.766-0.847). Further, in our study, we found that an increased risk of AIS was associated with serum TRX levels ≥11.0 ng/mL (adjusted OR 6.99; 95 % CI, 2.87-12.87) after adjusting for possible confounders. Our study demonstrated that serum TRX levels at admission were associated with stroke severity and lesion volumes. Elevated levels could be considered as a novel, independent diagnosis marker of AIS in a Chinese sample. PMID:25520003

  10. A possible mechanism for the decrease in serum thyroxine level by phenobarbital in rodents

    International Nuclear Information System (INIS)

    Effects of phenobarbital (PB) on the levels of serum thyroid hormones such as total thyroxine (T4) and triiodothyronine were examined in male mice, hamsters, rats, and guinea pigs. One day after the final administration of PB (80 mg/kg, intraperitoneal, once daily for 4 days), significant decreases in the levels of the serum total T4 and free T4 occurred in mice, hamsters, and rats, while a significant decrease in the level of serum triiodothyronine was observed in hamsters and rats among the animals examined. In addition, a significant decrease in the level of serum thyroid-stimulating hormone was observed in only hamsters among the rodents examined. Significant increases in the level and activity of hepatic T4-UDP-glucuronosyltransferase (UGT1A) after the PB administration occurred in mice, hamsters, and rats, while the increase in the amount of biliary [125I]T4-glucuronide after an intravenous injection of [125I]T4 to the PB-pretreated animals occurred only in rats. In mice, rats, and hamsters, but not guinea pigs, PB pretreatment promoted the clearance of [125I]T4 from the serum, led to a significant increase in the steady-state distribution volumes of [125I]T4, and raised the concentration ratio (Kp value) of the liver to serum and the liver distribution of [125I]T4. The present findings indicate that the PB-mediated decreases in the serum T4 level in mice, hamsters, and rats, but not guinea pigs, occur mainly through an increase in the accumulation level of T4 in the liver.

    Full Text Available Liver fatty acid-binding protein (L-FABP, also known as fatty acid-binding protein 1 (FABP1, is a key regulator of hepatic lipid metabolism. Elevated FABP1 levels are associated with an increased risk of cardiovascular disease (CVD and metabolic syndromes. In this study, we examine the association of FABP1 gene promoter variants with serum FABP1 and lipid levels in a Chinese population. Four promoter single-nucleotide polymorphisms (SNPs of FABP1 gene were genotyped in a cross-sectional survey of healthy volunteers (n = 1,182 from Fuzhou city of China. Results showed that only the rs2919872 G>A variant was significantly associated with serum TG concentration(P = 0.032.Compared with the rs2919872 G allele, rs2919872 A allele contributed significantly to reduced serum TG concentration, and this allele dramatically decreased the FABP1 promoter activity(P < 0.05. The rs2919872 A allele carriers had considerably lower serum FABP1 levels than G allele carriers (P < 0.01. In the multivariable linear regression analysis, the rs2919872 A allele was negatively associated with serum FABP1 levels (β = -0.320, P = 0.003, while serum TG levels were positively associated with serum FABP1 levels (β = 0.487, P = 0.014. Our data suggest that compared with the rs2919872 G allele, the rs2919872 A allele reduces the transcriptional activity of FABP1 promoter, and thereby may link FABP1 gene variation to TG level in humans.

    AIM: To explore any gender-related differences in prevalence of and condition-associated factors related to an elevated serum alanine aminotransferase (ALT) level amongst residents of Kinmen, Taiwan.METHODS: A total of 11 898 of a potential 20 112 regional residents aged 30 years or more completed a related questionnaire that was carried out by the Yang-Ming Crusade between 1991 and 1994 inclusively, with blood samples being collected by public nurses. The overall questionnaire response rate was 59.3% (52.4% for males and 66.0% for females).RESULTS: The prevalence of an elevated serum ALT level for this sub-population was found to be 7,2%, the prevalence revealing a statistically significant decrease with increasing population age (P<0.0001). Males exhibited a greater prevalence of elevated serum ALT level than did females (9.4% vs 5.3%, P<0.0001). Using multiple logistic regression analysis, in addition to male gender, a younger age, greater waist circumference,presence of type-2 diabetes and hyperuricemia were the significant factors associated with an elevated serum ALT level for both males and females. Gender-related differences as regards associated factors were also revealed. For males, obesity was significantly related to an elevated serum ALT level (OR = 1.28, 95%CI: 1.00-1.66)but this was not so for females (OR = 1.09, 95%CI:0.84-1.42). Hypertriglyceridemia (OR = 1.80, 95%CI:1.36-2.39) and hyperuricemia (OR = 1.61, 95%CI:1.03-2.52) were significantly related to elevated serum ALT levels only for females.CONCLUSION: Several gender-related differences were noted pertaining to the prevalence of and relationship between obesity, hypertriglyceridemia and hyperuricemia and elevated serum ALT level in the present study.(c)2005 The WJG Press and Elsevier Ihc.

    A 40-year-old woman was admitted to our hospital because of pancytopenia with megaloblastic anemia. Two months later she complained of rapidly progressive gait disturbance and numbness in the distal part of limbs. She also told that her hair had turned totally gray in the third decade. Neurologically, mental state, cranial nerves and cerebellar functions were normal. Superficial sensations were impaired below the lower thoracic level and deep sensations were completely lost in the lower limbs. Moderate weakness was found in the lower limbs, symmetrically. Deep tendon reflexes were diminished in the upper limbs and absent in the lower limbs. Babinski's reflex was positive bilaterally. MR images of the spinal cord showed hyperintensity in the posterior column below the thoracic cord. Although the serum level of vitamin B12 was within normal range, serum homocysteine level was elevated markedly. Under the diagnosis of subacute combined degeneration (SCD) due to possible vitamin B12 deficiency, the treatment with intravenous injections of 500 micrograms/day of mecobalamin was undertaken. Muscle strength and sensory impairment improved progressively and she became able to walk with a cane. The coloration of her gray hair was also noted. After treatment, pancytopenia and megaloblastic anemia also markedly improved. Vitamin B12 became high in serum concentration and the serum level of homocysteine became normal. These clinical and laboratory findings support the diagnosis of SCD with normal serum level of vitamin B12 in our case, suggesting that the level of vitamin B12 in serum does not always correlate with that in tissue and, therefore, SCD should not be excluded just only by the reason of normal serum vitamin B12 level.

    The aim of percutaneous transhepatic biliary drainage (PTBD) is to decrease serum bilirubin level and promote liver function in patient with biliary tract disease, especially obstruction by malignant disease. But some patients showed persistent high serum bilirubin level or higher than pre-PTBD level. Percutaneous transhepatic biliary drainage was performed in 341 patients of obstructive jaundice for 5 years form July, 1981 to July, 1986 at department of radiology, Seoul National University Hospital. Follow up check of the serum bilirubin level was possible in 188 patients. Among them the authors analysed 32 patients who showed persistent high serum bilirubin level after PTBD. The results were as follows: 1. The male to female ratio was 3.4:1 and the age ranged from 33 to 75. 2. The causes of obstructive jaundice included 30 malignant diseases and 2 benign diseases. Malignant disease were 16 cases of bile duct carcinoma, 7 cases of pancreatic cancer and 7 cases of metastasis from stomach, colon and uterine cervix. Benign disease were 1 case of common hepatic duct stone and 1 case of intrahepatic duct stones. 3. The most common level of obstruction was trifurcation in 17 cases. 4. The most common indication of PTBD was palliative drainage of obstruction secondary to malignant tumor in 28 cases. 5. Change of serum bilirubin level ratio (post-PTBD level/pre-PTBD level) was 1.28, 1.22, 1.38, 1.51 in serial period of 1-3 days, 4-6 days, 1-2 week 2-3 week after PTBD. 6. Causes of persistent high serum bilirubin level after PTBD were 12 cases of partial drainage of intrahepatic bile, 13 cases of hepatic dysfunction including 9 cases of metastatic nodule, 2 cases of biliary cirrhosis, 2 cases of multiple liver abscess, and 7 cases of poor function of catheter including 4 cases of hemobilia, 1 case of multiple intrahepatic stones, pyobilia and intrahepatic Clonorchis sinensis.

  6. Biochemical Evaluation of Serum Adiponectin Level in Egyptian Breast Cancer Patients before and after Treatment

    International Nuclear Information System (INIS)

    In this study, serum adiponectin level was evaluated in 35 primary breast cancer patients and 10 healthy females, before and after treatment to assess if there is a relation between it and breast cancer, and to find out if it has a prognostic value. Serum adiponectin level was significantly lower in all and postmenopausal breast cancer patients before taking any type of treatment, and non-significantly lower in locally advanced breast cancer patients after treatment by 4 cycles of neoadjuvant chemotherapy than healthy controls. Non-significant elevations was shown after treatment by surgery, and also after completing treatment by surgery followed by taking 2 cycles of adjuvant chemotherapy followed by treatment by radiotherapy in case of premenopausal locally advanced breast cancer patients. Triglycerides showed significantly higher level in all groups of patients. There was statistical negative correlation between serum adiponectin level and body mass index (BMI) in postmenopausal healthy controls, and between serum adiponectin level and BMI, triglycerides in all and postmenopausal breast cancer patients before taking any type of treatment. In conclusion, this study suggests that low serum adiponectin level is likely to be associated with increased breast cancer risk, particularly among postmenopausal women. The association between obesity and breast cancer risk might be partly explained by adiponectin

  7. Aldolase A isoenzyme levels in serum and tissues of patients with liver diseases

    International Nuclear Information System (INIS)

    A radioimmunoassay specific for human aldolase A was used to measure human aldolase A levels in human tissue and serum of patients with various liver diseases. The method was a double-antibody technique using radio-iodinated purified aldolase A, chicken antibody to aldolase A, and rabbit antibody to chicken immunoglobulin G. Normal liver tissue contains only a small amount of aldolase A. In contrast, aldolase A predominates in liver cell carcinoma tissue. Aldolase A levels in the sera of normal subjects were 171 +/- 39 ng/ml (mean +/- 2 SD). In almost all of the nonmalignant liver diseases, the aldolase A levels remained less than 210 ng/ml. The serum aldolase A levels increased remarkable only in fulminant hepatitis. in contrast, 32 of 34 patients with liver cell carcinoma and all of 29 patients with metastatic liver carcinoma showed clearly increased serum aldolase A levels. More patients with primary liver cell carcinoma had increased serum aldolase A levels than elevations of serum alpha-fetoprotein. These results suggest that the determination of aldolase A by radioimmunoassay may be useful to differentiate malignant form nonmalignant liver diseases

  8. Significance of post-operative changes of serum IL-18 levels in patients with renal transplantation

    International Nuclear Information System (INIS)

    Objective: To study the clinical significance of post-operative changes of serum IL-18 levels in patients after renal transplantation. Methods: Serum IL-18 levels were detected with ELISA in 33 patients with renal transplantation before operation and repeated again on d5, d10 and d20 post-operatively as well as in 35 controls. Results: Pre-operatively, serum IL-18 levels in patients for upcoming renal transplantation were significantly higher than those in controls (P<0.01). After operation, the IL-18 levels on d5 and d10 in patients with acute rejection were not significantly changed from those pre-operatively but were markedly increased on d20 (vs pre-operative, d5, d10; all P<0.01). In the patients without rejection, levels in d5 were significantly higher than those pre-operatively, but dropped to approaching pre-operative values on d10 and d20. On d20, levels of serum IL-18 in patients with rejection were very significantly higher than those in stable patients (P<0.01). Conclusion: Serum IL-18 is a useful marker for identifying acute rejection. (authors)

  9. Study on the changes of serum levels of ANF in patients with atrial fibrillation (AF)

    International Nuclear Information System (INIS)

    Objective: To study the changes of serum levels of ANF in patients with atrial fibrillation and to explore the mechanism of the prethrombotic state induced by AF. Methods: Serum levels of ANF were measured with RIA in 21 patients with isolated paroxysmal atrial fibrillation (IPAF) both during and one week after termination of the attack. Levels were also measured in 28 patients with isolated sustained atrial fibrillation (ISAF), 27 patients with rheumatic mitral stenosis associated with persistent AF (RHD), 32 patients with paroxysmal supraventricular tachycardia (PSVT) and 35 controls. Results: Serum levels of ANF and Hct% readings in: 1) patients with IPAF during attack 2) patients with ISAF and 3) patients with RHD were significantly higher than those in: 1) patients with IPAF one week after termination of the attack 2) patients with PSVT and 3) the controls (p<0.05). Values in patients with PSVT were not much different from those in controls. In patients with IPAF during the attack, serum ANF levels and Hct% readings were positively correlated to the duration of the attack. Serum ANF levels were not related to such parameters as: age, sex, mitral valve area, ejection fraction and inner diameter of left atrium. Conclusion: There is hemoconcentration in patients with atrial fibrillation, which is related to the hypersecretion of ANF in these patients

    Endogenous sex hormones seem to influence the risk of several common and debilitating diseases. With a view toward better understanding the effects of surgical removal of the ovaries and high-dose pelvic radiotherapy on plasma sex hormone levels, we measured estrogen and androgen concentrations cross-sectionally among 147 women who had been treated for cervical cancer 0.3-18.5 years previously. Pelvic radiotherapy (mean dose to ovaries, 50 Gy) and bilateral ovariectomy were associated with similarly reduced hormone concentrations relative to levels among nonirradiated women with intact ovaries, most of whom had had early-stage disease and were treated by hysterectomy. There was little evidence that radiotherapy in addition to ovariectomy further lowered concentrations below levels associated with ovariectomy alone, such as might be expected if radiation was suppressing adrenal endocrine function. Among women age 50 years or older at the time of blood drawing, the removal or irradiation of the ovaries was associated with approximately 45% lower concentrations of estradiol (mean ratio [MR], 0.55; 95% confidence interval [CI], 0.32-0.95) and testosterone (MR, 0.57; 95% CI, 0.32-0.99), and 25-30% lower concentrations of estrone (MR, 0.69; 95% CI, 0.44-1.09) and androstenedione (MR, 0.76; 95% CI, 0.47-1.23), relative to the hysterectomy-only group. Among women younger than 50, ovariectomy and radiotherapy, alone or in combination, were associated with 83% lower estradiol concentrations (MR, 0.17; 95% CI, 0.09-0.31), 46% lower estrone concentrations (MR, 0.54; 95% CI, 0.37-0.81), 23% lower androstenedione concentrations (MR, 0.77; 95% CI, 0.57-1.04), and 14% lower testosterone levels (MR, 0.86; 95% CI, 0.64-1.15).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8118384

    Serum vitamin B12 and erythrocyte folate levels were determined in a group of healthy women eating a balanced diet. Approximately 50% were using oral contraceptives. Vitamin B12 levels were lower in the oral contraceptive users. However, their folate levels were no different from those of non-users. Age had no effect on either vitamin B12 or folate levels. Oral contraceptive users taking multiple vitamin tablets containing vitamin B12 and folate had slightly higher folate levels, but their vi...

    Observational epidemiological evidence supports a linear inverse and independent association between serum total bilirubin levels and coronary heart disease (CHD) risk, but whether this association is causal remains to be ascertained. A Mendelian randomization approach was employed to test whether serum total bilirubin is causally linked to CHD. The genetic variant rs6742078--well known to specifically modify levels of serum total bilirubin and accounting for up to 20% of the variance in circulating serum total bilirubin levels--was used as an instrumental variable. In pooled analysis of estimates reported from published genome-wide association studies, every copy of the T allele of rs6742078 was associated with 0.42 standard deviation (SD) higher levels of serum total bilirubin (95% confidence interval, 0.40 to 0.43). Based on combined data from the Coronary Artery Disease Genome wide Replication and Meta-analyses and the Coronary Artery Disease (C4D) Genetics Consortium involving a total of 36,763 CHD cases and 76,997 controls, the odds ratio for CHD per copy of the T allele was 1.01 (95% confidence interval, 0.99 to 1.04). The odds ratio of CHD for a 1 SD genetically elevated serum total bilirubin level was 1.03 (95% confidence interval, 0.98 to 1.09). The current findings casts doubt on a strong causal association of serum total bilirubin levels with CHD. The inverse associations demonstrated in observational studies may be driven by biases such as unmeasured confounding and/or reverse causation. However, further research in large-scale consortia is needed. PMID:26408227

    Aim: The eicosanoids derived from phospholipids play key roles in inflammation. However, the profiles of serum eicosanoids in subclinical hypothyroidism (SH) patients and the effects of thyroxine replacement therapy (TRT) on these eicosanoids remain unclear. Many studies show that TSH regulates lipid metabolism. As eicosanoids derived from phospholipids play key roles in oxidative stress and immune function and inflammatory process, it was necessary to explore the profiles of serum eicosanoids in SH patients and the effects of thyroxine replacement therapy (TRT) on the eicosanoids. Methods: A total of 50 Chinese SH patients and 22 healthy volunteers were recruited. SH patients received TRT (L-T4, 25 and 50 mcg/d for patients with TSH≤10.0 mIU/L and TSH>10.0 mIU/L, respectively) for 3 months. Serum levels of major eicosanoids and cPLA2 were analyzed using LC-MS and clinical biochemical assays. Results: The serum levels of cPLA2, eicosanoids (8-isoPGF2a, 11-dehydroTXB2 and 12-HETE) and 11-dehydroTXB2/6-Keto-PGF1a were significantly elevated in SH patients. The serum TSH levels were significantly correlated with the levels of cPLA2 (r=+0.65), 11-dehydroTXB2 (r=+0.32) and 11-dehydroTXB2/6-Keto-PGF1a (r=+0.37). After 3-month TRT, the serum levels of TSH, cPLA2 and the above-mentioned eicosanoids in SH patients were significantly decreased. Conclusion: The metabolism of eicosanoids is significantly altered in Chinese SH patients, and TRT can ameliorate the abnormalities of serum eicosanoid levels. PMID:26997566

    Full Text Available Depression is a serious and potentially life-threatening mental disorder with unknown etiology. Emerging evidence shows that brain-derived neurotrophic factor (BDNF and microRNAs (miRNAs play critical roles in the etiology of depression. Here this study was aimed to identify and characterize the roles of BDNF and its putative regulatory miRNAs in depression. First, we identified that miR-182 may be a putative miRNA that regulates BDNF levels by bioinformatic studies, and characterized the effects of miR-182 on the BDNF levels using cell-based studies, side by side with miR-132 (a known miRNA that regulates BDNF expression. We showed that treatment of miR-132 and miR-182 respectively decreased the BDNF protein levels in a human neuronal cell model, supporting the regulatory roles of miR-132 and miR-182 on the BDNF expression. Furthermore, we explored the roles of miR-132 and miR-182 on the BDNF levels in depression using human subjects by assessing their serum levels. Compared with the healthy controls, patients with depression showed lower serum BDNF levels (via the enzyme-linked immunosorbent assays and higher serum miR-132 and miR-182 levels (via the real-time PCR. Finally, the Pearson's (or Spearman's correlation coefficient was calculated to study whether there was a relationship among the Self-Rating Depression Scale score, the serum BDNF levels, and serum BDNF-related miRNA levels. Our results revealed that there was a significant negative correlation between the SDS scores and the serum BDNF levels, and a positive correlation between the SDS scores and miR-132 levels. In addition, we found a reverse relationship between the serum BDNF levels and the miR-132/miR-182 levels in depression. Collectively, we provided evidence supporting that miR-182 is a putative BDNF-regulatory miRNA, and suggested that the serum BDNF and its related miRNAs may be utilized as important biomarkers in the diagnosis or as therapeutic targets of depression.

  16. Serum levels of MMP-11 correlate with clinical outcome in Chinese patients with advanced gastric adenocarcinoma

    International Nuclear Information System (INIS)

    The aim of the present study was to investigate the association between serum levels of matrix metalloproteinase 11 (MMP-11) and responses to front-line chemotherapy and prognosis in advanced unresectable gastric adenocarcinoma. Clinical data concerning 86 patients with advanced gastric adenocarcinoma (stages III c to IV), treated in Beijing Chao-Yang Hospital from 2005 to 2009, were reviewed retrospectively. Adenocarcinoma was confirmed by pathology and patients received 5-fluorouracil-based front-line combination chemotherapy with third generation chemotherapeutic agents including paclitaxel, docetaxel and oxaliplatin. The regimen was repeated every two to three weeks, and the first evaluation was carried out after three cycles. The median cycle of chemotherapy was 6 (ranging from three to twelve cycles). Serum MMP-11 protein from the 86 patients was examined using enzyme-linked-immunosorbent-assay (ELISA) prior to chemotherapy and after three cycles of chemotherapy. Serum samples from healthy individuals were used as controls. The response rate (RR, complete response plus partial response) to chemotherapy in the 86 patients was 44.2% (38/86). The median TTP (time to progression) and overall survival (OS) in patients who responded to chemotherapy were 6.0 and 10.0 months, respectively. The response rate to chemotherapy in patients with high levels of serum MMP-11 (42.9%; 9/21) was similar to that in patients with low levels (44.6%; 29/65) (P = 0.935). Patients with low serum levels of MMP-11 had a higher median survival time and 1-year survival rate than those with high levels (11 months vs. 8 months, 50.2% vs. 21.7%, P = 0.017), although the TTP was comparable in all patients, irrespective of serum MMP-11 level (P = 0.178). Serum MMP-11 levels were correlated with lymph node metastasis (P = 0.006). Cox multivariate regression analysis demonstrated that the serum level of MMP-11 was an independent prognostic factor for patients presenting with advanced gastric

  17. Dynamic changes of serum IL-6 levels in rate models with pristane induced arthritis

    International Nuclear Information System (INIS)

    Objective: To study the dynamic changes of serum IL-6 levels in rat models with pristane induced arthritis. Methods: Rat models of arthritis were prepared with subcutaneous injection of pristane, serum IL-6 levels were determined with RIA in the rat models before pristane injection and 1, 3, 5, 8w later. Results: Serum IL-6 levels in the rat models were significantly higher 1, 3, 8 w after pristane injection than those before injection (P<0.01). The levels dropped significantly 5w after injection (vs 1wk P<0.01), but rose again with a second peak at 8w. Conclusion: IL-6 possibly participated in the initiation progression and relapse of the pristane induced arthritis in rat models. (authors)

    In many patients with low serum levels of vitamin B12, the absorption of the free vitamin has been normal. The present study, using a total body counter 57CoB12 absorption method that clearly separated those with intrinsic factor deficiency from controls, found that of 94 patients with low B12 levels and intact stomachs in whom the absorption of free and bound B12 was determined, 44 (47%) had normal absorption of both. However, 20 of the 94 (21%) with normal absorption of free B12 had low absorption of bound B12. The remainder (32%) had low absorption of both free and bound B12. All patients with high serum gastrin levels had low bound B12 absorption, but so did 21% of those patients with normal serum gastrin levels. PMID:1609768

  19. Clinical significance of the changes of serum leptin levels in patients with acute cerebral infarction

    International Nuclear Information System (INIS)

    Objective: To study the relationship between cerebral infarction and changes of serum leptin and to explore the occurrence mechanism of cerebral infarction. Methods: Serum leptin (with RIA) levels were measured in 79 patients with CT proved cerebral infarction and 56 controls. Results: The serum leptin levels in patients with cerebral infarction were significantly higher than those in the controls (t=3.99, P<0.01), with no difference between the levels in mild and severe patients. Conclusion: There are hyperleptinemia and leptin resistance in cerebral infarction patients. Leptin takes part in regulation of energy equilibrium. Increase of leptin level is a risk marker for cerebral infarction and further study on the mechanism is needed. (authors)

  20. Effect of high altitude (3685 meter) on the serum levels of female sex hormones (progesterone, estradiol)

    International Nuclear Information System (INIS)

    Objective: To study the effect of high altitude hypoxia on the secretion of female sex hormones. Methods: Serum progesterone (P) and estradiol (E2) levels were measured with RIA in 738 women who were moved from plain to Lhasa (3685 meter) and stayed there for various years and 430 controls. Results: The serum P and E2 levels in the newly arrived subjects (within one year) were significantly lower than those in the controls. The levels gradually increased as acclimation occurred (up to 20 year) but dropped again later (probably due to advancing age). Conclusion: Hypoxia might be the cause of decreasing serum famale sex hormones levels in subjects moved to high altitude. (authors)

    Hepatic steatosis is commonly seen in the patients withchronic hepatitis C virus (HCV) infection. HCV is closelyassociated with lipid metabolism, and viral steatosis ismore common in genotype 3 infection owing to a directcytopathic effect of HCV core protein. In non-genotype3 infection, hepatic steatosis is considered largely tobe the result of the alterations in host metabolism;metabolic steatosis is primarily linked with HCV genotype1. Adipose tissue secretes different hormonesinvolved in glucose and lipid metabolisms. It has beendemonstrated that adipocytokines are involved in thepathogenesis of non-alcoholic fatty liver disease, as thedecreased plasma adiponectin levels, a soluble matrixprotein expressed by adipoctyes and hepatocyte, areassociated with liver steatosis. Various studies haveshown that steatosis is strongly correlated negativelywith adiponectin in the patients with HCV infection.The role of adiponectin in hepatitis C virus inducedsteatosis is still not completely understood, but therelationship between adiponectin low levels and liversteatosis is probably due to the ability of adiponectinto protect hepatocytes from triglyceride accumulationby increasing β-oxidation of free fatty acid and thusdecreasing de novo free fatty acid production.

  2. Serum calcium and magnesium level in dairy cows at calving

    Full Text Available Milk fever and hypocalcaemia are post-partum metabolic diseases affecting about 6% of dairy cows and are due to a fail of the homeostatic metabolism regulating the calcium blood level around 9 and 10mg/100mL. The calcium drainage to the mammary gland along with the reduced capacity of the animal to mobilize calcium from bone reserve lead to a drop of the calcium blood level under 5-6mg/100mL with paresis like clinical symptoms known as milk fever. The incidence of the clinical milk fever is low, however the occurrence of mild hypocalcaemia (subclinical could be as high as 15- 20% within few days after calving, particularly in multiparous cows. The hypocalcaemia status as for the reduced bone calcium mobilization and intestinal absorption leads to reduced feed intake and make it a good start for ketosis, retained placenta, displaced abomasums and mastitis problems (Beede, 1991. The acid-base balance of the cow in the late pregnancy is determinant for hypocalcaemia............

    The objective of this study was to determine the levels of serum copper and zinc in subclinically hypocalcemic peripartum dairy cows in comparison to healthy animals. Blood samples were taken from 219 multiparous Holstein cows near parturition (from 4 weeks prepartum to 4 weeks postpartum) and 51 cows with subclinical hypocalcemia. The results showed that the serum copper concentration increased gradually at 1 week prepartum and remained high for the first 4 weeks postpartum in the healthy periparturient dairy cows. The serum zinc concentration reached a nadir at 1 week postpartum and subsequently increased gradually to baseline. The serum zinc concentration was significantly decreased (Pcows with subclinical hypocalcemia compared with healthy cows. There was no significant difference in the serum copper concentration between cows with subclinical hypocalcemia and healthy cows. These data demonstrate that the concentrations of copper and zinc in serum change dramatically during the peripartum period in dairy cows, which is a tremendous challenge for the body and for the maintenance of dairy cow health. The present study further suggests that a decreased serum zinc concentration could be a cause of decreased productive performance and increased susceptibility to other diseases due to immunosuppression in dairy cows with subclinical hypocalcemia. Additionally, this decreased zinc concentration may be involved in the pathogenesis of subclinical hypocalcemia. PMID:24859816

  4. Low serum hdl-c levels: a hidden threat to patients with spinal cord injury

    International Nuclear Information System (INIS)

    To determine the serum lipid profile in patients with traumatic spinal cord injury (SCI) of duration >1 year and to compare the serum HDL-c levels of SCI patients undergoing regular physiotherapy for >60 minutes daily with those who did not Undergo physiotherapy. Study Design: Cross-sectional, comparative study. Place and Duration of Study: Spinal Cord Injury Department, AFIRM Rawalpindi and Department of Chemical Pathology, Army Medical College, Rawalpindi, from January 2013 to June 2013. Patients and Methods: Forty six patients suffering from traumatic spinal cord injury (SCI) were included. After recording the detailed medical history, fasting blood samples were obtained and analyzed for serum lipid profile. Dyslipidemias were assessed using guidelines from the National Cholesterol Education Project Adult Treatment Panel III (ATP III). Serum high-density lipoprotein cholesterol (HDL-c)< 0.9 mmol/l (40mg/dl) was considered as low HDL-c level. Results: Out of total 46 patients, 33 (71.7%) were male and 13 (28.3%) were females with mean age of 34.9+- 9.55 years. Low levels of serum HDL-c were found in 21 (45.7%) SCI patients (mean serum HDL-clevels: 0.97+-0.23). SCI patients were further categorized in two groups depending upon the status of regular physiotherapy. Statistically significant difference was found in mean serum HDL-c levels of 22 (47.82%) SCI patients undergoing regular physiotherapy as compared to 24 (52.18%) SCI patients who did not underwent physiotherapy (p<0.05). Conclusion: Patients with SCI have decreased levels of serum HDL-c, imparting an increased risk of cardiovascular disease (CVD) in these disabled persons. SCI individuals following regular physiotherapy, have better serum HDL-c levels as compared to bed-ridden SCI patients, suggesting the physical activity as an important factor to elevate the serum HDL-c in such patients. Knowledge of relative risk of CVD in persons with SCI is important for appropriate intervention alstrategies

    International Nuclear Information System (INIS)

    Using ELISA and IRMA respectively detected IL-10 and IgE levels in the serum of 50 patients with acute asthma and 48 healthy persons. Results show IL-10 levels in the serum of patients with asthma is obviously lower than that of healthy persons (P<0.01), but IgE levels in them are obviously higher than that of healthy persons (P<0.01), there is negative correlation between IL-10 and IgE (r=-0.18, P<0.01). Suggesting that IL-10 is insufficient and IgE is high in patients with asthma may be one of important causes of asthma

    Full Text Available Introduction: The effect of Tribulus terrestris (TT on serum glucose and lipid levels was investigated in an experimental model of diabetes mellitus in rats. Methods: Female Wistar rats were divided into control, TT-treated control, diabetic, glibenclamide-treated, and TT-treated diabetic groups. For induction of diabetes, streptozotcin (STZ was administered (60 mg/Kg. Meanwhile, TT-treated groups received TT mixed with standard pelleted food at a weight ratio of 6.25% for 6 weeks. Serum glucose and lipid levels were determined before the study and at the 3rd and 4th week after the study. Results: Serum glucose was significantly lower in TT-treated diabetic rats at 3rd and 6th weeks as compared to untreated diabetics (p<0.01 and p<0.005, respectively. In addition, serum total cholesterol, triglyceride, and LDL-cholesterol showed a significant reduction in TT-treated diabetic rats as compared to untreated diabetics (p<0.05. On the other hand, HDL-cholesterol level did not change significantly in TT-treated diabetic group as compared to untreated diabetic group. Conclusions: Oral administration of TT has a significant hypoglycemic effect and in long term leads to appropriate changes in serum LDL-cholesterol, total cholesterol, and triglyceride levels, but does not affect HDL-cholesterol levels in diabetic rats.

    Stress has inhibitory effect on HPG axis through increasing cortisol serum level. In this study, the effect of acute prepubertal stress on kisspeptin, which plays essential role in puberty achievement is assessed. To do this experimental study thirty immature healthy male wistar rats of 4 weeks old and without any symptoms of puberty were selected randomly. These rats were divided into three groups, randomly. Two groups were chosen as control and pretest and one as stress (test) group. Immobilization stress was applied for 10 days and serum level of cortisol, testosterone and kisspeptin were measured. Primary and secondary spermatocyte and sertoli cell evaluated and compared among groups. Mean serum level of kisspeptin in pretest group, control group and stress (test) group were 0.0381 ± 0.0079, 91.0500 ± 4.87430 and 15.2156 ± 3.88135 pg mL(-1) respectively. Serum level of kisspeptin had significant differences between three groups (p stress led to decrease in serum level of kisspeptin and testosterone in stress (test) group compared to control groups. Also stress caused a significant decrease in the numbers of secondary spermatocytes of the test group. PMID:26930799

    Full Text Available Context Several experimental studies have been carried out to explain the ph ysiopathological mechan isms and to introduce endocrinological, enzymatic, biochemical and histopathol ogical changes in organism s during acute pancreatitis. Objective To evaluate the effect of an intraperitoneal injection of melatonin on serum amylase levels. Design Experimental acut e pancreatitis was experimentally caused through panc reatic duct ligation in 20 Winstar Albino rats . The rats were then divided into two groups: control and melatonin groups. Intervention The serum amylase level was measured on the 7 th day after acute pancreatitis had developed. In the melatonin group, an intraperitoneal injecti on of melatonin (20 mg/kg/day was performed starting from the 2 nd day after pancreatic duct ligation. Main outcome measure The levels of serum amylase were measured with an auto analyzer. Results It was found that the mean (±SD level of serum amylase in th e control group was 947±182 IU/mL wh ile it was 358±177 IU/mL in the experimental group (P<0.001. Conclusions The 20 mg/kg/day intraperitoneal injection of melatonin which was carried out for one week attenuated the serum amylase levels to a statistically si gnificant degree. The researchers believe that intraperitoneal in jections of melatonin decrease the severity of acute pancreatitis.

    AIM To investigate the serum levels of vascular endothelial growth factor receptor-2 (VEGFR-2) and adropin in age-related macular degeneration (AMD) patients. METHODS Ninety-eight AMD patients were included in the study. Seventy-eight age- and sex-matched healthy volunteers were recruited as the control group. Fundus florescein angiography and optical coherence tomography were performed to assess the posterior segment details. Serum VEGFR-2 and adropin levels were measured using enzyme-linked immunosorbent assays and compared between the study groups. RESULTS AMD group had significantly increased foveal retinal thickness, serum LDL and HDL levels and significantly decreased subfoveal choroidal thickness (P =0.01, 0.047, 0.025 and AMD patients compared to controls (26.48±6.44 vs 30.42±7.92 ng/mL, PAMD patients (6.17±3.19 vs 5.79±2.71 ng/mL, P=0.4). Serum level of VEGFR-2 in AMD patients had a significant negative correlation with foveal retinal thickness (r=-0.226, P=0.025) and a significant positive correlation with subfoveal choroidal thickness (r=0.2, P=0.048). CONCLUSION The current study demonstrated that the decreased serum VEGFR-2 level may be considered in the development of AMD. Adropin does not seem to play a role in the pathogenesis of AMD.

    Background Adiponectin, secreted by adipocytes, has been found to be associated with diabetes, obesity and some cardiovascular diseases. Obstructive sleep apnea hypopnea syndrome (OSAHS) is also closely related to obesity and easily complicated with diabetes and some cardiovascular diseases. This study was carried out to explore the change of serum adiponectin level in patients with OSAHS.Methods Polysomnography was performed in 71 patients with OSAHS (OSAHS group) and 26 simple obese controls (control group). The two groups had no significant difference in age and body mass index (BMI). Radioimmunoassy was used to test serum adiponectin level.Results Serum adiponectin level was significantly lower in OSAHS group [(5.03±1.01) mg/L] than that in the control group [(7.09±1.29) mg/L, P<0.05]. The differences between two groups were independent of gender. In OSAHS groups, serum adiponectin levels were negatively correlated with apnea hypopnea index (AHI) (r=-0.78, P<0.01), BMI (r=-0.13, P<0.05), waist circumsference (r=-0.36, P<0.01), and neck circumference (r=-0.42, P<0.01), but positively correlated with the minimal pulse oxyhemoglobin saturation (r=0.48, P<0.01). Conclusion OSAHS may contribute to the decrease of serum adiponectin level independent of obesity.

    Full Text Available Background: Preeclampsia is a pregnancy-specific disease associated with significant maternal and perinatal mortality and morbidity. Lipid abnormality and elevated serum uric acid have been reported as early features of the disease. We aimed to detect the level of serum lipid profile and uric acid abnormalities in severe preeclamptics in Benin City and to measure their clinical significance. Materials and Methods: A prospective case-control study was conducted with subjects presenting with severe preeclampsia to the Obstetric Unit of the UBTH, Benin City. Fasting serum lipid profile and uric acid levels of 40 severe preeclamptic subjects and 80 gestation-matched normotensive controls were done at recruitment. The preeclamptic subjects were managed according to our departmental protocol which included stabilisation and delivery. Their sociodemographic and clinical characteristics were used to generate a database for analysis. Results: The mean serum uric acid level was 28% higher in severe preeclamptics than normotensive women (5.96 ± 2.54 mg/dl versus 4.30 ± 0.85; P = 0.005. There were statistically significant differences in levels of triglycerides (TG, low-density lipoprotein (LDL and high-density lipoprotein (HDL between the preeclamptics and their normotensive controls (P = 0.006, P = 0.000, P = 0.000, respectively. Abnormal serum uric acid was associated with advanced maternal age (P = 0.000, early-onset preeclampsia (P = 0.000 and abnormal body mass index (BMI; P = 0.000. Low birth weight was more likely in preeclamptics with elevated serum uric acid levels (P = 0.041. Conclusion: Abnormality of serum uric acid in preeclampsia was significantly associated with increased frequency of complications but lipid profile abnormalities were not shown in the subjects studied. We recommend a larger scale study to determine lipid profile in normal and complicated pregnancies in our environment.

    Objective: To determine the frequency of perirenal hyperintensity on heavily T2-weighted images and to evaluate its relationship with serum creatinine levels. Subjects and methods: Axial and coronal single-shot fast spin-echo images which have been originally obtained for MR cholangiopancreatography in 150 subjects were examined by two observers individually for the presence of perirenal hyperintensity. The morphologic properties of perirenal hyperintensity (peripheral rim-like, discontinuous, polar) were recorded. Chi square test was used to test whether the frequencies of bilateral perirenal hyperintensity differ significantly in subjects with high serum creatinine levels and those with normal creatinine levels. This test was also used to compare the frequencies of perirenal hyperintensity in patients with and without renal cysts and in patients with and without corticomedullary differentiation. A p value of less than 0.05 was considered to be statistically significant. Results: The perirenal hyperintensity was identified in 40 of 150 cases (26.6%) on heavily T2-weighted image. Serum creatinine levels were high in 18 of 150 cases (12%). The perirenal hyperintensity was present in 11 of 18 subjects (61%) with high serum creatinine levels and 26 of 132 subjects (19.7%) with normal creatinine levels. The difference of rates in two groups was statistically significant. Odds ratio was 6407 (95% confidence interval 2264-18,129). The frequency of perirenal hyperintensity was also significantly higher in subjects with renal cyst or cysts in whom serum creatinine levels were normal (p < 0.05) (37.5% vs. 11.8%). Conclusion: Perirenal hyperintensities are more frequent in patients with high serum creatinine levels. They are also more common in patients with simple renal cysts.

    Background The relationship between serum homocysteine levels and non-alcoholic fatty liver disease is poorly understood. This study aims to investigate the sex-specific relationship between serum homocysteine level and non-alcoholic fatty liver disease in the Korean population. Methods This cross-sectional study included 150 men and 132 women who participated in medical examination programs in Korea from January 2014 to December 2014. Patients were screened for fatty liver by abdominal ultrasound and patient blood samples were collected to measure homocysteine levels. Patients that consumed more than 20 grams of alcohol per day were excluded from this study. Results The homocysteine level (11.56 vs. 8.05 nmol/L) and the proportion of non-alcoholic fatty liver disease (60.7% vs. 19.7%) were significantly higher in men than in women. In men, elevated serum homocysteine levels were associated with a greater prevalence of non-alcoholic fatty liver disease (quartile 1, 43.6%; quartile 4, 80.6%; P=0.01); however, in females, there was no significant association between serum homocysteine levels and the prevalence of non-alcoholic fatty liver disease. In the logistic regression model adjusted for age and potential confounding parameters, the odds ratio for men was significantly higher in the uppermost quartile (model 3, quartile 4: odds ratio, 6.78; 95% confidential interval, 1.67 to 27.56); however, serum homocysteine levels in women were not associated with non-alcoholic fatty liver disease in the crude model or in models adjusted for confounders. Conclusion Serum homocysteine levels were associated with the prevalence of non-alcoholic fatty liver disease in men. PMID:27468343

    Full Text Available The adipocyte hormone leptin is thought to serve as a signal to the central nervous system reflecting the status of fat stores. Serum leptin levels and adipocyte leptin messenger RNA levels are clearly increased in obesity. Nevertheless, the factors regulating leptin production are not fully understood. The aim of this study was to determine the effects of in vivo administration of the synthetic glucocorticoid dexamethasone and weight loss on serum leptin levels in two independent protocols. Twenty-five obese subjects were studied (18 women and 7 men, mean age 26.6 ± 6 years, BMI 31.1 ± 2.5 kg/m², %fat 40.3 ± 8.3 and compared at baseline to 22 healthy individuals. Serum levels of leptin, insulin, proinsulin and glucose were assessed at baseline and after ingestion of dexamethasone, 4 mg per day (2 mg, twice daily for two consecutive days. To study the effects of weight loss on serum leptin, 17 of the obese subjects were submitted to a low-calorie dietary intervention trial for 8 weeks and again blood samples were collected. Serum leptin levels were significantly higher in the obese group compared to the control group and a high positive correlation between leptinemia and the magnitude of fat mass was found (r = 0.88, P<0.0001. After dexamethasone, there was a significant increase in serum leptin levels (22.9 ± 12.3 vs 51.4 ± 23.3 ng/ml, P<0.05. Weight loss (86.1 ± 15.1 vs 80.6 ± 14.2 kg, P<0.05 led to a reduction in leptin levels (25.13 ± 12.8 vs 15.9 ± 9.1 ng/ml, P<0.05. We conclude that serum leptin levels are primordially dependent on fat mass magnitude. Glucocorticoids at supraphysiologic levels are potent secretagogues of leptin in obese subjects and a mild fat mass reduction leads to a disproportionate decrease in serum leptin levels. This suggests that, in addition to the changes in fat mass, complex nutritional and hormonal interactions may also play an important role in the regulation of leptin levels.

    Introduction: Polychlorobiphenyls (PCBs) are persistent pollutants that are widespread in the environment and in foodstuffs, particularly in freshwater fish, which frequently exceed the maximum levels set by European regulations. Objectives: First, we describe the consumption of freshwater fish and serum PCB levels in French anglers, a population expected to have the highest level of dietary PCB exposure. Second, we investigated whether there is a statistical relationship between serum PCB levels and the angler consumption of freshwater fish with high PCB bioaccumulation potential (PCB-BP{sup +} freshwater fish) in order to make recommendations with regard to safe consumption of freshwater fish. Methods: We conducted a survey of anglers from six sites with contrasting PCB contamination levels. The survey included a food consumption frequency questionnaire and blood samples were taken to assess serum PCB levels. We used a regression model to determine the main factors contributing to serum PCB levels. Results: Consumption of PCB-BP{sup +} freshwater fish was relatively infrequent. Serum PCB levels of the study population and of women of childbearing age were in the same range as those observed in the French population and in neighbouring European countries, but higher than in the North American population. The two factors with the highest positive association with serum PCB levels were age (R{sup 2} = 61%) and the consumption of PCB-BP{sup +} freshwater fish (R{sup 2} = 2%). Using the regression model, we calculated, for several scenarios depending on the age and gender of the population, the maximum annual frequencies for PCB-BP{sup +} freshwater fish consumption that do not exceed the critical body burden threshold. Conclusion: Following the results of this study, the French agency for food, environmental and occupational health and safety (ANSES) issued an opinion and recommended some specific maximum freshwater fish consumption frequencies to protect the French

    Full Text Available TREM-1 and TREM-2 molecules are members of the TREM transmembrane glycoproteins. In our previous study we identified increased expressions of TREM-1 and TREM-2 receptors in pulmonary sarcoidosis (PS. Only a few studies concerning the association between vitamin D and TREM receptor expression can be found. The aim of our current study was to determine the association between the levels of an inactive form of 25(OHD vitamin and TREM-1 and TREM-2 receptor expressions. We have detected low levels of 25(OHD vitamin in 79% of PS patients. Only 21% of patients had normal serum level of 25(OHD vitamin with values clustered within the low-normal range. The most striking findings were the increased TREM-2 expressions on myeloid cells surfaces in BALF of PS patients with normal 25(OHD vitamin serum levels compared with those with its decreased levels. The total number of TREM-2 positive cells was 5.7 times higher and the percentage of TREM-2 positive cells was also significantly increased in BALF of PS patients with normal compared to PS patients with low 25(OHD vitamin serum levels. A significant correlation between total TREM-2 expression and vitamin D levels has been detected too. However, we have not detected similar differences in TREM-1expression and 25(OHD vitamin serum levels.

    Full Text Available Heroin addiction is a chronic, complex disease, often accompanied by other concomitant disorders, which may encumber effective prevention and treatment. To explore the differences in expression profiles of serum proteins in control and heroin addicts, we used two-dimensional electrophoresis coupled to MALDI-TOF/TOF, and identified 4 proteins of interest. Following validation of the increase in serum transthyretin, we assessed serum levels of thyroid stimulating hormone (TSH, triiodothyronine (T3, and thyroxine (T4, and observed a robust increase in T4 in heroin addicts compared to controls. In addition, we performed haptoglobin (Hp phenotyping, and showed that the frequency of Hp0 (serum devoid of haptoglobin was significantly higher in heroin addicts. Altogether, these findings indicated that: (1 thyroid hormone imbalance is present in heroin addicts; (2 anhaptoglobinemia (Hp0 might a risk factor or a deleterious effect of heroin abuse.

    Pesticide exposure has been implicated as an environmental risk factor for the development of Parkinson's disease (PD). However, few studies have identified specific pesticides. Previously, we identified elevated serum levels of the organochlorine pesticide β-hexachlorocyclohexane (β-HCH) in PD patients from a small clinical sample. Here, we conducted a case-control study to confirm the association between β-HCH and PD in a larger sample size (n=283) with serum samples of PD patients and controls obtained from UT Southwestern Medical Center and Emory University. Samples were obtained from two discrete periods at both sites, 2001-2003 and 2006-2008, and were analyzed for β-HCH levels. Adjusted odds ratios (ORs) for PD were estimated using logistic regression and generalized estimating equations. The mean serum β-HCH level across all cohorts in this study was 22.3 ng/mg cholesterol (range: 0-376.7), and the levels were significantly higher and samples collected in 2001-2003 vs. 2006-2008. After controlling for age and gender, the OR for increased risk of PD for every 1 ng/mg increase in serum β-HCH ranged from 1.02 to 1.12 across the four different cohorts, and 1.03 (95% CI: 1.00-1.07, p value=0.031) in the pooled analysis. Furthermore, the OR for increased risk of PD of subjects having serum β-HCH levels above the inter-quartile range of 39.08 ng/mg cholesterol was 2.85 (95% CI: 1.8, 4.48; p value<0.001). These data are consistent with environmental decreases in β-HCH levels between 2001 and 2008, but they indicate that elevated levels of serum β-HCH are still associated with heightened risk for PD.

    Full Text Available Background: Although the precise etiology of multiple sclerosis (MS is unknown, it seems that both genetic and environmental factors are important. Recent studies suggest that low serum vitamin D levels are important environmental factor in MS. The aim of this study was to compare the serum levels of vitamin D between MS patients and healthy subjects, and to determine its association with disability in MS patients.Methods: In this cross-sectional study, a total of52 patients with MS were randomly recruited and matched for age and sex with 52 healthy subjects. Demographic characteristics and serum vitamin D levels for both groups, as well as duration of disease Expanded Disability Status Scale (EDSS for MS patients were evaluated. Statistical analysis was performed by independent samples t-test and multiple linear regression analysis.Results: The mean serum vitamin D levels were26.5 ± 16.3 ng/ml in MS patients vs. 37.1 ±19.7 in healthy subjects (P = 0.003. A linear regression analysis showed no significant association between vitamin D levels and EDSS score of patients with MS (P = 0.345, after adjusting for the covariates.Conclusion: Our findings did not suggest a protective association for serum vitamin D levels against disability in MS patients.Methods: In this comparative cross-sectional study, a total of 52 patients with MS were randomly recruited and matched for age and sex with 52 healthy subjects. Demographic characteristics and serum vitamin D levels for both groups, as well as duration of disease Expanded Disability Status Scale (EDSS for MS patients were evaluated. Statistical analysis was performed by independent samples t-test and multiple linear regression analysis.Results: The mean serum vitamin D levels were 26.50±16.33 ng/ml in MS patients vs. 37.14±19.69 in healthy subjects (P< 0.003. A linear regression analysis showed no significant association between vitamin D levels and EDSS score of patients with MS (P= 0.345, after

    International Nuclear Information System (INIS)

    Objective: To investigate the changes of serum hormones before and after uterine artery embolization. Methods: 27 cases of uterine fibroids were performed with uterine artery embolization (UAE). In all cases, follicle stimulating hormone (FSH), luteinizing hormone (LH) and estriol (E2) were measured before and after the UAE. Results: The serum levels of FSH before embolization were (8.63 +- 10.33) IU/L and (15.8 +- 27.89) IU/L months after embolization. The serum levels of LH before embolization were (11.77 +- 12.21) IU/L and (25.79 +- 37.24) IU/L3 months after embolization. The serum levels of E2 before embolization were (160 +- 67) pg/ml and (184 +- 87) pg/ml 3 months after embolization. There was no statistical difference between the measurements of FSH, LH, E2 before UAE and after UAE (P > 0.05, t TEST). But FSH, LH, E2 appeared to have menopause change in two cases. Conclusions: Uterine artery embolization would not affect the serum levels of FSH, LH and E2

    International Nuclear Information System (INIS)

    To observe the serum levels of epidermal growth factor (EGF) in patients with hepatitis B and cirrhosis, the levels of serum EGF in 108 patients with hepatitis B, chronic mild, moderate, severe hepatitis B and liver cirrhosis before and after treatment were detected by RIA. Hyaturonic acid (HA), laminin (LN), procollagen type III(PC III) and collagen type IV(C-IV) were also assayed in these patients, and 30 healthy blood donors served as normal control. The serum levels of EGF in patient with hepatitis B were remarkably higher than those in nomal control. After treatment, the serum levels of EGF, HA, LN, PCIII and C-III were decreased significantly compared with those before treatment (P<0.01). EGF were positively correlated with HA, LN, PCIII and C-IV. The results suggested that determination of serum EGF more times may be of value in assessment of the seveity of liver inflammation and fibrosis. It may also be used to observe the therapeutic effect. (authors)

    Serum cystatin C concentration was recently reported as a marker of cardiovascular disease (CVD). In the present study, we evaluated the association between the increase of serum cystatin C levels and the risk of CVD in type 2 diabetes. 42 patients with type 2 diabetes were included in the present study; 27 of them have CVD. The control group consisted of 30 healthy adults. Cystatin C, creatinine, microalbuminuria and CRP were measured on Cobas 6000(TM). Cystatine C level was significantly higher in patients with CVD. A significant difference in serum cystatin C was found in patients with and without CVD among albuminuria. No difference in serum cystatin C levels was found according to number of affected vessels. A cystatin C level above 1.10 mg/L was associated with increase of risk of CVD with significant difference (OR = 42.52; IC 95% 1.455 to 1242.827 and p = 0.029). Our results suggested that the increase of serum cystatin C concentrations is a potential marker for CVD in diabetes. PMID:23906571

    Liver fibrogenesis involves the synthesis of collagen fibrils and proteoglycans by various types of liver cells, including Ito cells, transitional cells, myofibroblasts and hepatocytes. Synthesis of collagen fibrils follows a complex metabolic pathway with intermediate products such as type III procollagen (III-PC). Serum levels of III-PC may reflect the activity of the fibrogenetic process. We analysed the relationship between the serum levels of III-PC (N-terminal peptide) and diverse clinical, biochemical and histological parameters of 77 alcoholic patients (27 cirrhotics), comparing them with those of 15 age- and sex-matched controls. A highly significant difference was obtained between controls and patients (P less than 0.0001), but no differences were observed between cirrhotics and non-cirrhotics. Serum III-PC significantly correlated with clinical and biochemical data of liver function derangement (prothrombin activity, serum albumin, bilirubin, gynecomastia, ascites, encephalopathy, edema, splenomegaly); with the duration of ethanol addiction and with MCV. Sixty patients were followed up for a period ranging between 3 and 1056 days (mean = 356 days); 9 of them died. Patients with III-PC levels above 38 ng/ml had a significantly higher mortality (P = 0.006) than those with levels under 38 (log rank test). Thus, serum III-PC may be a useful tool in the clinical evaluation and prognostic assessment of patients with chronic alcoholic liver disease. PMID:2323314

  15. Effect of feeding garlic (allium sativum) on body weight and serum cholesterol levels in rats

    International Nuclear Information System (INIS)

    Background: Oral garlic supplementation may be effective in decreasing serum cholesterol levels as much as 15% to 20%. Garlic indirectly effect atherosclerosis by reduction of hyperlipidaemia, hypertension and probably diabetes mellitus and prevents thrombus formation. This study was undertaken to test the hypothesis that garlic powder with a prolonged mode of action promises potent biological effects into hypercholesterolaemia. Methods: Fifty albino rats were randomly divided into 5 equal groups (n=10). All rats were initially fed normal diet for at least 7 days. Then Group A was control and was fed a normal diet + 0.5% cholesterol, Group B was fed normal diet and 3 mg garlic per 10 g of feed and Group C was fed normal diet and 10 mg garlic per 10 g of feed. The experiment lasted for 12 weeks. Body weight and serum cholesterol were noted before and after giving garlic + cholesterol. Results: Effect of serum cholesterol level was significantly decreased after taking 3 and 10 mg of garlic. However it was observed that the body weight was increased after taking garlic. Conclusion: Garlic consumption although can decrease the level of serum cholesterol but it increases the body weight. Garlic consumption alone can decrease serum cholesterol level, but it cannot be used as the main therapeutic agent for hyperlipidaemia. (author)

  16. Serum levels of perfluoroalkyl compounds in human maternal and umbilical cord blood samples

    International Nuclear Information System (INIS)

    Perfluoroalkyl compounds (PFCs) are end-stage metabolic products from industrial flourochemicals used in the manufacture of plastics, textiles, and electronics that are widely distributed in the environment. The objective of the present study was to quantify exposure to perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), perfluorodecanoic acid (PFDeA), perfluorohexane sulfonate (PFHxS), perfluoroheptanoic acid (PFHpA), and perfluorononanoic acid (PFNA) in serum samples collected from pregnant women and the umbilical cord at delivery. Pregnant women (n=101) presenting for second trimester ultrasound were recruited and PFC residue levels were quantified in maternal serum at 24-28 weeks of pregnancy, at delivery, and in umbilical cord blood (UCB; n=105) by liquid chromatography-mass spectrometry. Paired t-test and multiple regression analysis were performed to determine the relationship between the concentrations of each analyte at different sample collection time points. PFOA and PFOS were detectable in all serum samples analyzed including the UCB. PFOS serum levels (mean±S.D.) were significantly higher (p<0.001) in second trimester maternal serum (18.1±10.9 ng/mL) than maternal serum levels at delivery (16.2±10.4 ng/mL), which were higher than the levels found in UCB (7.3±5.8 ng/mL; p<0.001). PFHxS was quantifiable in 46/101 (45.5%) maternal and 21/105 (20%) UCB samples with a mean concentration of 4.05±12.3 and 5.05±12.9 ng/mL, respectively. There was no association between serum PFCs at any time point studied and birth weight. Taken together our data demonstrate that although there is widespread exposure to PFCs during development, these exposures do not affect birth weight

    Full Text Available Background: The measuring serum ferritin level as a sensitive inflammatory biomarker might effectively predict preterm delivery, but the power and the best cut-off point of this biomarker for predicting preterm labor in Iranian population has not been substantially identified. Our purpose was to determine what concentrations of serum ferritin could identify patients at risk for preterm delivery in Iranian population for the first time. Materials and Methods: This case control study involved 222 singleton pregnancies that were referred to referral university hospitals clinics in Isfahan. Women with spontaneous preterm delivery before 24-26 weeks (preterm delivery group, n = 69 and those who delivered at term (term delivery group, n = 153 were compared with respect to serum ferritin concentration. Venous blood samples were analyzed for the serum ferritin level using the ferritin quantitative test system-sensitive for the normal ferritin range. Results: Women who delivered before 37 weeks had a higher mean serum ferritin concentration than those who delivered after 37 weeks of gestation (26.7 ± 5.5 ng/mL versus 19.8 ± 3.6 ng/mL, P<0.001. A serum ferritin level of 22.5 ng/mL yielded the best combination with sensitivity of 78.3%, specificity of 83.0%, positive predictive value of 67.5%, and negative predictive value of 89.4% for prediction of preterm delivery. Conclusion: The serum ferritin level provides an appropriate discrimination in predicting preterm delivery with an optimal cut-off value of 22.5 ng/mL in Iranian population.

  18. Relationship between serum TNF-α, IL-8 levels and acute coronary syndrome in aged patients

    International Nuclear Information System (INIS)

    Objective: To study the relationship between serum levels of TNF-α, IL-8 and the severity of coronary heart disease in aged patients and to assess the usefulness of these two cytokines as markers of atheromatous plaque stability. Methods: Serum TNF-α, IL-8 levels were determined with RIA in 85 aged patients with coronary heart disease, in which 42 were of the acute coronary syndrome type (ACS) and 43 were of the stable coronary heart disease type (SCHD) as well as in 30 controls. Results: Serum levels of TNF-α, IL-8 in both the patients with ACS and SCHD were significantly higher than those in controls ( P 0.05). Conclusion: The cytokines TNF-α and IL-8 were regarded as important markers for stability of the atheromatous plaque. However, data from this article did not give much support to that hypothesis (no significant difference data). (authors)

    Full Text Available Carbohydrate antigen 19-9 (CA 19-9 is a sensitive marker for pancreatic and hepatobiliary malignancies. The highest frequency of elevated serum CA 19-9 levels is found among patients with pancreatic cancer. CA 19-9 has recently been demonstrated to be a marker of digestive tract malignancies. We report the case of a patient with a gastric cancer and a very high serum CA 19-9 level. During laparotomy, a large mass was found in the antrum. A distal gastrectomy with D2 dissection of the lymph nodes was performed. Histological examination, including immunohistochemistry, revealed an adenocarcinoma of the stomach producing CA 19-9. To the best of our knowledge, no patient with an extremely high serum CA 19-9 level resulting from a gastric adenocarcinoma has been reported previously.
