    Full Text Available OBJECTIVE: Serum levels of soluble TNF-like weak inducer of apoptosis (sTWEAK and its scavenger receptor CD163 (sCD163 have been linked to insulin resistance. We analysed the usefulness of these cytokines as biomarkers of type 2 diabetes in a Spanish cohort, together with their relationship to food consumption in the setting of the Di@bet.es study. RESEARCH DESIGN AND METHODS: This is a cross-sectional, matched case-control study of 514 type 2 diabetes subjects and 517 controls with a Normal Oral Glucose Tolerance Test (NOGTT, using data from the Di@bet.es study. Study variables included clinical and demographic structured survey, food frequency questionnaire and physical examination. Serum concentrations of sTWEAK and sCD163 were measured by ELISA. Linear regression analysis determined which variables were related to sTWEAK and sCD163 levels. Logistic regression analysis was used to estimate odd ratios of presenting type 2 diabetes. RESULTS: sCD163 concentrations and sCD163/sTWEAK ratio were 11.0% and 15.0% higher, respectively, (P<0.001 in type 2 diabetes than in controls. Following adjustment for various confounders, the OR for presenting type 2 diabetes in subjects in the highest vs the lowest tertile of sCD163 was [(OR, 2,01 (95%CI, 1,46-2,97; P for trend <0.001]. Coffee and red wine consumption was negatively associated with serum levels of sCD163 (P = 0.0001 and; P = 0.002 for coffee and red wine intake, respectively. CONCLUSIONS: High circulating levels of sCD163 are associated with type 2 diabetes in the Spanish population. The association between coffee and red wine intake and these biomarkers deserves further study to confirm its potential role in type 2 diabetes.

    Sickle cell disease (SCD) is characterized by vasculopathy, which has been causally linked to intravascular haemolysis and high levels of free plasma haemoglobin. Soluble CD163 (sCD163) is implicated in the clearance of free plasma haemoglobin and high plasma concentrations have been linked...... to arterial disease. We therefore investigated the value of sCD163 as a biomarker in children with SCD, and also measured haptoglobin levels in this population. We measured sCD163 in 25 control children with no haemoglobinopathy, 41 with sickle cell anaemia (HbSS) in the steady state, 27 with HbSS taking...

    CD163 is an endocytic receptor for haptoglobin-hemoglobin complexes and is expressed solely on macrophages and monocytes. As a result of ectodomain shedding, the extracellular portion of CD163 circulates in blood as a soluble protein (sCD163) at 0.7-3.9 mg/l in healthy individuals. The function...... of sCD163 is unknown, but during inflammation and macrophage activation, sCD163 levels increase acutely due to metalloproteinase-mediated cleavage near the cell membrane. It is now evident that sCD163 is very useful as a biomarker of macrophage activation in various inflammatory diseases......, such as macrophage activation syndrome, sepsis, and liver disease. Moreover, sCD163 is a general risk marker of comorbidity and mortality in several chronic inflammatory disease states. Recently, sCD163 has been shown to be strongly associated with later development of type 2 diabetes in both lean and obese subjects...

    CD163 is a hemoglobin scavenger receptor exclusively expressed in the monocyte-macrophage system. A particularly high expression is seen in macrophages of the 'alternative activation' phenotype playing a major role in dampening the inflammatory response and in scavenging components of damaged cells....... CD163-mediated endocytosis of haptoglobin-hemoglobin complexes formed upon red blood cell hemolysis leads to lysosomal degradation of the ligand protein and metabolism of heme by cytosolic heme oxygenase. In accordance with a stimulated expression of haptoglobin, CD163 and heme oxygenase-1 during...... the acute phase response, there is evidence that this metabolic pathway regulates inflammation by at least two ways. First, CD163 is reported to directly induce intracellular signaling leading to secretion of anti-inflammatory cytokines. Second and perhaps even more important, the CD163-mediated delivery...

    Anders G Kjærgaard

    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. CONCLUSION: Serum sCD163 is superior to PCT and CRP for the diagnosis of sepsis and

    Clinical outcomes are positively associated with hematoma absorption. The monocyte-macrophage scavenger receptor, CD163, plays an important role in the metabolism of hemoglobin, and a soluble form of CD163 is present in plasma and other tissue lfuids;therefore, we speculated that serum CD163 affects hematoma absorption after intracerebral hemorrhage. Patients with intracerebral hemorrhage were divided into high-and low-level groups according to the average CD163 level (1,977.79 ± 832.91 ng/mL). Compared with the high-level group, the low-level group had a signiifcantly slower hematoma absorption rate, and signiifcantly increased National Institutes of Health Stroke Scale scores and modiifed Rankin Scale scores. These results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.

    Increased levels of monocyte-platelet aggregates (MPAs) are reported to be highly correlated with cardiovascular events. In this study, the MPA levels in different monocyte subsets and the associations between MPA levels, HIV-1 viremia and monocyte activation were evaluated during HIV-1 infection. The results showed that the percentages of MPAs in all three monocyte subsets were higher in HIV-1-infected subjects than in healthy controls, and were associated with the plasma viral load in the non-classical and intermediate monocyte subsets. The plasma levels of sCD14 and sCD163 were upregulated in HIV-1 infection and were positively associated with viral loads and negatively associated with CD4 counts. P-selectin glycoprotein ligand-1 (PSGL-1) was shown to be expressed at significantly lower levels on all three monocyte subsets and was negatively correlated with the sCD163 level. The MPA level was correlated with the levels of plasma sCD163 but negatively correlated with CD163 and PSGL-1 on all three monocyte subsets. An elevated immune activation status was correlated with increased MPA formation, underlying the potential interaction between monocyte activation and MPA formation. This interaction may be related to a higher thromboembolic risk in patients infected with HIV-1.Cellular & Molecular Immunology advance online publication, 11 August 2014; doi:10.1038/cmi.2014.66.

    CD163 is expressed on cells of monocyte-macrophage lineage and is the main hemoglobin-haptoglobin receptor. Inflammation and monocyte activation are predisposing factors to vaso-occlusion and pulmonary hypertension, which are serious complications in sickle cell disease (SCD). Siblings of SCD patients may have the same pathophysiology without displaying symptoms. We assessed soluble CD163 (sCD163) levels in 60 children with SCD and 30 sickle cell trait (SCT) siblings compared with 30 healthy controls as a potential marker for disease severity and treatment response. Patients were studied stressing on the presence of pulmonary hypertension by Dopplar-Echocardiography, sickling crisis, transfusion requirements, hydroxyurea response, hematological profile, high sensitivity C-reactive protein (hs-CRP) and serum sCD163. sCD163 was significantly elevated in SCD patients and SCT siblings compared with controls and the highest levels were in untreated SCD patients (P < 0.001). sCD163 was higher in patients with pulmonary hypertension, acute chest syndrome or stroke as well as in patients who developed sickling crisis during the study period (P < 0.05). Hydroxyurea-treated patients had lower sCD163 compared with untreated patients (P < 0.001). sCD163 was positively correlated to leukocyte count, HbS, hs-CRP, pulmonary artery pressure and tricuspid regurgitant velocity whereas inversely correlated to hemoglobin and HbF levels. The cut-off value of sCD163 at 1400 ng/ml could be considered a predictor for vaso-occlusive crisis in SCD with a sensitivity of 92.3% and specificity of 94.1%. sCD163 can be considered a biomarker for pulmonary hypertension, early crisis prediction and monitoring hydroxyurea response in SCD patients. Elevated sCD163 in trait siblings could reflect increased risk of sickling in challenging situations.

    -purified sCD163 from serum migrated as a single band of 130kDa, and spanned at least 945 amino acids (94%) of the total extra-cellular part of CD163. In solution sCD163 only weakly competed for Hp-Hb uptake in CD163-expressing cells, and Hp-Hb saturation of sCD163 in serum was only seen with large excess...... of Hp-Hb complexes. However, upon immobilisation, recombinant sCD163 bound Hp-Hb with high affinity. This suggests that Hp-Hb is less dissociable when bound to the membrane form of CD163, presumably because of the di- or multivalent nature of Hp-Hp complexes in terms of CD163 binding. CONCLUSIONS: Serum...

    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.

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

Recent reports showed that CD163 expression was associated with angiogenesis. In this study, overexpression of CD163 in BMSCs elevated the protein level of the endothelial-associated markers CD31, Flk-1, eNOS, and VE-cadherin, significantly increased the proportion of Alexa Fluor 488-acetylated-LDL-positive VECs, and promoted angiogenesis on Matrigel. Furthermore, we demonstrated that CD163 acted downstream homeobox containing 1 (Hmbox1 and upstream fibroblast growth factor 2 (FGF-2. These data suggested that CD163 was involved in Hmbox1/CD163/FGF-2 signal pathway in BMSC differentiation into vascular endothelial-like cells. We found a new signal pathway and a novel target for further investigating the gene control of BMSC differentiation into a VEC lineage.

    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.

    2015-06-01

    Full Text Available In inflammatory diseases, macrophages are a main producer of a range of cytokines regulating the inflammatory state. This also includes inflammation induced by tumor growth, which recruits so-called tumor-associated macrophages supporting tumor growth. Macrophages are therefore relevant targets for cytotoxic or phenotype-modulating drugs in the treatment of inflammatory and cancerous diseases. Such targeting of macrophages has been tried using the natural propensity of macrophages to non-specifically phagocytose circulating foreign particulate material. In addition, the specific targeting of macrophage-expressed receptors has been used in order to obtain a selective uptake in macrophages and reduce adverse effects of off-target delivery of drugs. CD163 is a highly expressed macrophage-specific endocytic receptor that has been studied for intracellular delivery of small molecule drugs to macrophages using targeted liposomes or antibody drug conjugates. This review will focus on the biology of CD163 and its potential role as a target for selective macrophage targeting compared with other macrophage targeting approaches.

    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.

    Systemic inflammation induces cytokine synthesis within the central nervous system. This results in sickness behaviour and may exacerbate ongoing neuroinflammatory disease. The precise mechanisms underlying the relay of signal from the periphery to the central nervous system are not entirely understood. CD163-positive macrophages occupy a unique position at the blood-brain barrier and upregulate prostaglandin-synthesizing enzymes in response to systemic inflammation. This finding suggests tha...

    Gadolinium-based contrast agents are linked to nephrogenic systemic fibrosis in patients with renal insufficiency. The pathology of nephrogenic systemic fibrosis is characterized by abnormal tissue repair: fibrosis and ectopic ossification. The mechanisms by which gadolinium could induce fibrosis and ossification are not known. We examined in vitro the effect of a gadolinium-based contrast agent on human peripheral blood mononuclear cells for phenotype and function relevant to the pathology of nephrogenic systemic fibrosis using immunofluorescence, flow cytometry, real-time PCR, and osteogenic assays. We also examined tissues from patients with nephrogenic systemic fibrosis, using IHC to identify the presence of cells with phenotype induced by gadolinium. Gadolinium contrast induced differentiation of human peripheral blood mononuclear cells into a unique cellular phenotype--CD163(+) cells expressing proteins involved in fibrosis and bone formation. These cells express fibroblast growth factor (FGF)23, osteoblast transcription factors Runt-related transcription factor 2, and osterix, and show an osteogenic phenotype in in vitro assays. We show in vivo the presence of CD163(+)/procollagen-1(+)/osteocalcin(+) cells in the fibrotic and calcified tissues of nephrogenic systemic fibrosis patients. Gadolinium contrast-induced CD163(+)/ferroportin(+)/FGF23(+) cells with osteogenic potential may play a role in systemic fibrosis and ectopic ossification in nephrogenic systemic fibrosis.

    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

    During intravascular hemolysis hemoglobin (Hb) binds to haptoglobin (Hp) leading to endocytosis of the complex by the macrophage receptor, CD163. In the present study, we used a phage-display Fab antibody strategy to explore if the complex formation between Hp and Hb leads to exposure of antigenic...... epitopes specific for the complex. By Hp-Hb-affinity screening of a phage-Fab library, we isolated a phage clone against the ligand complex. Surface plasmon resonance analyses of the Fab part expressed as a recombinant protein revealed a high affinity binding (KD = 3.9 nm) to Hp-Hb, whereas no binding...... was measured for non-complexed Hp or Hb. The Fab antibody completely inhibited the binding of 125I-labeled Hp-Hb complexes to CD163 and blocked their uptake in CD163-transfected cells. In conclusion, we have raised a receptor-blocking antibody specifically recognizing the Hp-Hb complex. In addition to provide...

    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

    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.

    UNLABELLED: Increasing evidence supports a decisive role for inflammation in the neurodegenerative process of Parkinson's disease (PD). The immune response in PD seems to involve, not only microglia, but also other immune cells infiltrated into the brain. Indeed, we observed here the infiltration...... of macrophages, specifically CD163+ macrophages, into the area of neurodegeneration in the 6-hydroxydopamine (6-OHDA) PD model. Therefore, we investigated the therapeutic potential of the infiltrated CD163+ macrophages to modulate local microglia in the brain to achieve neuroprotection. To do so, we designed...... intravenous CD163-targeted liposomes with Dexa for 3 weeks exhibited better motor performance than the control groups and had minimal glucocorticoid-driven side effects. Furthermore, these animals showed better survival of dopaminergic neurons in substantia nigra and an increased number of microglia...

    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

  11. Maternal serum levels of adiponectin in preeclampsia

    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)

    Subfertility is a major reproductive health problem all over the world as well as Bangladesh, and the problem is increasing day by day. This study was done to estimate the serum prolactin concentration in primary and secondary subfertile women. Laboratory investigation included serum prolactin level, as well as LH, FSH, TSH blood glucose (2 hours after 75 gm glucose load) of 50 women who attended infertility unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from March 2009 and February 2010. In most cases, common age group 26-30 years (52%), primary subfertility (74%), duration of marriage >5 years (60%), trying to conceive duration ≤5 years (54%), BMI >25 kg/m² (60%), menstrual cycle regular (58%), history of abortion absent (90%), and history of menstrual regulation absent (94%). Common investigation findings was normal serum follicle stimulating hormone (FSH) 1.0-10.0 mIU/ml in 82%, normal serum luteinizing hormone (LH) 1.0-10.0 mIU/ml in 50%, normal serum prolactin 1.9-25.0 ng/ml in 36%, normal serum thyroid stimulating hormone (TSH) 0.4-4.0 μIU/ml in 56%, and normal blood glucose level (2 hours after breakfast) (prolactin concentration may have role to play in subfertility of women.

    2014-05-01

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

    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.

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

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

    Porcine reproductive and respiratory syndrome (PRRS) is an economically important swine disease to the swine industry worldwide. Current PRRS vaccines are only partially effective and new vaccine development faces great challenges. Sialoadhesin (Sn) and CD163 are the two essential receptors for PRRSV infection of porcine alveolar macrophage (PAM). To investigate the feasibility of the soluble viral receptors for PRRS control, in the present study we generated recombinant adenovirus (rAd) expressing the four N-terminal Ig-like domains of porcine Sn (Sn4D), the fifth SRCR domain (SRCR5) or domains 5-9 (SRCR59) of porcine CD163 as porcine Fc (pFc) fusion proteins. Efficient expression of the soluble viral receptors in the rAd-transduced cells was confirmed by RT-PCR and Western blotting. To detect their antiviral activities, the soluble viral receptors were purified from the media of rAd-transduced cells and identified by Western blotting. The viral binding assay showed that the soluble receptors Sn4D-Fc and SRCR59-Fc, but not SRCR5-Fc and the control pFc, were able to bind to PRRSV particles. The viral infection blocking assays showed that co-treatment of PRRSV with different concentrations of Sn4D-Fc and SRCR59-Fc proteins resulted in a much higher (72.1%-77.6%) reduction in PRRSV-positive cell number than the single protein treatment (45.1%-60.0% or 44.0%-56.2%). To investigate the feasibility of delivering the soluble viral receptors to PAM, two pig cell lines were transduced with rAd-Sn4D-Fc and/or rAd-SRCR59-Fc using a transwell culture system. PAM cells were infected with PRRSV and then co-cultured with the rAd-transduced cells. Viral titration assay showed that co-cultivation of the infected PAM with rAd-Sn4D-Fc- and rAd-SRCR59-Fc-transduced cells resulted in much higher (by ∼3.5 log) reduction in the viral titers (TCID50) than that of co-cultivation with the single vector-transduced cells (by ∼1.0 log). Further studies showed that the rAd co

    Full Text Available Obesity and HIV-1/HAART-associated lipodystrophy syndrome (HALS share clinical, pathological and mechanistic features. Tumor necrosis factor-like weak inducer of apoptosis (TWEAK is a multifunctional cytokine that plays an important role in obesity and related diseases. We sought to explore the relationship between HALS and circulating levels of soluble (s TWEAK and its scavenger receptor sCD163.This was a cross-sectional multicenter study of 120 HIV-1-infected patients treated with a stable HAART regimen; 56 with overt HALS and 64 without HALS. Epidemiological and clinical variables were determined. Serum levels of sTWEAK and sCD163 levels were measured by ELISA. Results were analyzed with Student's t-test, Mann-Whitney U and χ2 test. Pearson and Spearman correlation were used to estimate the strength of association between variables.Circulating sTWEAK was significantly decreased in HALS patients compared with non-HALS patients (2.81±0.2 vs. 2.94±0.28 pg/mL, p = 0.018. No changes were observed in sCD163 levels in the studied cohorts. On multivariate analysis, a lower log sTWEAK concentration was independently associated with the presence of HALS (OR 0.027, 95% CI 0.001-0.521, p = 0.027.HALS is associated with decreased sTWEAK levels.

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

    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

    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

    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...

    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.

The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

    1989-08-01

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

  1. 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.

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

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.

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

    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.

  13. 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 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

  20. 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

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

    Full Text Available Problem statement: Smoking plays a significant role in the development of periodontal disease. Quantitative relation between smoking and increased severity of periodontal disease, by means of biochemical marker has not been described in Malaysian population. The present study was designed to apply serum cotinine measurement as a quantitative method to evaluate smoking levels in Malaysian patients and to correlate these levels with the severity of periodontal disease. Approach: The study group consisted of 80 healthy individuals (20-64 year, Current Smokers 26, Non Smokers 27 and Former Smokers 27. The subjects were then asked to complete a questionnaire including the demographic, socioeconomic status, medical history and history of cigarette smoking. The periodontal variables recorded were amount of Visible Plaque score, gingival bleeding Index and community periodontal index. Samples of blood “10 mL” were obtained in vacutainer tubes containing EDTA for quantitative analysis of serum levels of cotinine. The serum samples were analyzed for cotinine content by means of a competitive-inhibition ELISA technique. Results: Current smokers represent the highest mean cotinine serum level, 95.5 ng mL-1, compared to former smokers, 35.5 ng mL-1 and non smokers, 22.9 ng mL-1. The mean serum cotinine level in periodontally healthy patient showed the highest cotinine level (84 ng mL-1 followed by the gingivitis patients (68 ng mL-1 and (50 ng mL-1 for periodontitis patients. Conclusion: The present observations clearly indicate an association between smoking, periodontal disease clinical parameters “plaque, gingival bleeding scores” and cotinine serum levels in current smokers. Cotinine serum levels doesn’t affected by the existence or the severity of periodontal disease.

    Stroke is one of the leading causes of death and disability in developed as well as developing countries like Bangladesh. Elevated serum uric acid levels may predict an increased risk for cerebro-vascular (CV) events including stroke. Aim of the study was to measure the serum uric acid level among stroke patients and determine the relationship between serum uric acid level and stroke. This descriptive, cross-sectional study was carried out in Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh to measure serum uric acid level among 102 stroke patients in a period of one year by using non-probability sampling procedure. Finally, collected data were analyzed using SPSS software Version 17.0. It was observed that the mean age of patients was 60.87±8.05 years, of them 80(78.43%) patients were male and the rest 22(21.57%) were female. About 66(64.70%) of respondents were in age group 60 years and above, while 36(35.30%) were in age group 59 years and below. At least 23(22.55%) of stroke patients had elevated serum uric acid with a mean serum uric acid level of 5.18mg/dl and standard deviation 1.26mg/dl. About 23(27.38%) patients in ischemic stroke had elevated serum uric acid whereas 18(100%) patients in hemorrhagic stroke had normal uric acid level. Uric acid level was elevated in ischemic stroke than haemorrhagic stroke patients (p<0.001). High uric acid level may be considered as a risk factor in patients with acute ischemic stroke.

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

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

    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

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

    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.

    Full Text Available BACKGROUND : The purpose of the study was to analyze serum magnesium concentration in patients undergoing Aortic and Mitral Valve replacement surgeries. METHODS: This prospective study was conducted in 60 patients who underwent elective Aortic and Mitral va lve replacement surgeries. Blood samples from radial artery were collected just before induction of anesthesia and three days post - operatively for estimation of serum magnesium. RESULTS: Magnesium level was 2.02mg/dl at baseline, 2.28mg/dl, 2.08mg/dl and 1 .90mg/dl respectively on three consecutive days post - operatively. CONCLUSION: The lowering of serum magnesium in Aortic and Mitral valve replacement surgeries postoperatively recommends the use of routine serum magnesium determination and administration to prevent post - operative arrhythmias.

    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.

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

    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

    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.

    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.

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

    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.

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.

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

    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.

    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.

  4. CORRELATION OF GALLSTONE FORMATION WITH SERUM IRON LEVELS

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

    Full Text Available 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. 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.

    Full Text Available Cystatin C (Cys-C has been recently paid great attention as a better endogenous marker of the glomerular filtration rate than creatinine (Cr. In this study, the usefulness of Cys-C was compared with Cr in terms of the estimation of the steady-state serum trough concentrations of digoxin in Japanese patients. Forty patients treated with digoxin and 56 healthy elderly subjects were participated in this study. The serum levels of Cys-C and Cr in the patients were higher than those in the healthy elderly subjects, but the increase of Cys-C was more predominant in the patients. Their levels were well-correlated for both of the healthy elderly subjects (r=0.691 and patients (r=0.774, but the serum concentrations of digoxin were better correlated with those of the reciprocal values of Cr (r=0.667 than those of Cys-C (r=0.383, presumably due to the fact that digoxin and Cr were excreted via both glomerular filtration and tubular secretion. Cys-C is useful for the substratification of the patients diagnosed to have normal renal function with Cr of < 1.3 mg/dL into those with normal and pseudo-normal renal function, resulting in the corresponding serum concentrations of digoxin.

    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.

    Introduction Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports have evaluated serum vitamin D levels in vitiligo patients, and their results are conflicting. Aim To evaluate serum vitamin D levels of vitiligo patients and compare the results with controls. Material and methods In total, 50 vitiligo patients and 47 controls were enrolled in the study. Vitamin D levels were measured from blood samples. Group comparisons were performed using appropriate statistical methods. Results The patients had lower serum vitamin D levels than the controls, but this difference was not significant (p = 0.570). Conclusions It remains unknown whether vitamin D deficiency causes vitiligo. Larger controlled studies are required to prove whether low circulating vitamin D is a causative factor in vitiligo.

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

    In the present study serum glucose were estimated in pregnant women during the first trimester of pregnancy and third trimester of pregnancy to observe the frequency of hyperglycemia during pregnancy and to assess the incidence of gestational diabetes mellitus. This study was a cross sectional study, carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group. Study group was further divided into 100 pregnant women in first trimester of pregnancy and 100 pregnant women in third trimester of pregnancy. Diagnosed case of type I and type II diabetes, hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug users, regular steroid users were excluded from this study. Serum glucose was evaluated by the glucose-oxidase principle by GOD-PAP method in women with 1st trimester of pregnancy, 3rd trimester of pregnancy and in non pregnant women. Statistical analysis of data was done by unpaired student's t test. The results showed that the serum glucose levels increased significantly in third trimester and the value is not significant in first trimester. The increasing frequency of serum glucose level in third trimester may predispose the women to hyperglycemia of pregnancy or gestational diabetes mellitus. PMID:27277349

    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.

    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.

    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.

    2011-12-01

    Osteosarcoma is a rare malignant bone tumor most commonly occurring in children and young adults presenting with painful swelling. Various etiological factors for osteosarcoma are ionizing radiation, family history of bone disorders and cancer, chemicals (fluoride, beryllium, and vinyl chloride), and viruses. Status of fluoride levels in serum of osteosarcoma is still not clear. Recent reports have indicated that there is a link between fluoride exposure and osteosarcoma. Glycoproteins and glycosaminoglycans are an integral part of bone and prolonged exposure to fluoride for long duration has been shown to cause degradation of collagen and ground substance in bones. The present study was planned to analyze serum fluoride, sialic acid, calcium, phosphorus, and alkaline phosphatase levels in 25 patients of osteosarcoma and age- and sex-matched subjects with bone-forming tumours other than osteosarcoma and musculo-skeletal pain (controls, 25 each). Fluoride levels were analyzed by ISE and sialic acid was analyzed by Warren's method. Mean serum fluoride concentration was found to be significantly higher in patients with osteosarcoma as compared to the other two groups. The mean value of flouride in patients with other bone-forming tumors was approximately 50% of the group of osteosarcoma; however, it was significantly higher when compared with patients of group I. Serum sialic acid concentration was found to be significantly raised in patients with osteosarcoma as well as in the group with other bone-forming tumors as compared to the group of controls. There was, however, no significant difference in the group of patients of osteosarcoma when compared with group of patients with other bone-forming tumors. These results showing higher level of fluoride with osteosarcoma compared to others suggesting a role of fluoride in the disease.

    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...

    In a subset of high-altitude dwellers, the appropriate erythrocytotic response becomes excessive and can result in chronic mountain sickness. We studied men with (study group) and without excessive erythrocytosis (packed-cell volume >65%) living in Cerro de Pasco, Peru (altitude 4300 m), and compared them with controls living in Lima, Peru (at sea-level). Toxic serum cobalt concentrations were detected in 11 of 21 (52%) study participants with excessive erythrocytosis, but were undetectable in high altitude or sea-level controls. In the mining community of Cerro de Pasco, cobalt toxicity might be an important contributor to excessive erythrocytosis.

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 BACKGROUND: Tuberculosis is an important cause of morbidity and mortality in both adults and children, especially in developing countries. For prevention of childhood tuberculosis, BCG vaccination is advocated. Protection is attained 4 - 6 weeks after BCG vaccination a nd is mainly due to cell mediated immunity. After BCG vaccination almost 12 to 15% of neonates do not develop scar but have positive cell mediated immune response. ADA estimation is simple and inexpensive method to assess the cell mediated immunity. OBJECT IVE: To estimate serum ADA levels in children with and without BCG scar, after receiving BCG vaccination. MATERIAL AND METHODS: This prospective observational study was conducted at a tertiary care hospital for a period of 2 years. Babies in post natal ward and infants up to the age of 12 weeks attending well baby clinic for BCG vaccination were included in the study. Serum ADA lev els were estimated before BCG vaccination and 12 - 14 weeks after the vaccination. ADA levels were estimated by colorimetric method. Presence or absence of BCG scar was noted at 12 - 14 weeks of age. RESULTS: A total of 75 babies followed up, of which only 60 babies noted to have scar and in rest 15 babies there was no scar noticed. Twenty unvaccinated babies at 12 weeks of age were included as controls. The Mean ADA levels are significantly elevated after BCG vaccination (34 . 12 ± 3 . 28 U/L in comparison to le vels before vaccination (12 . 55± 2 . 64 U/L with p value 0. 06. CONCLUSION: After BCG vaccination, there is increase in serum ADA levels indicating adequ ate immunity. Increase in ADA levels in children without scar after BCG vaccination may indicate the probability of adequate immunity.

  6. Soluble α-Klotho Serum Levels in Chronic Kidney Disease

    Full Text Available Transmembrane α-Klotho (TM-Klotho, expressed in renal tubules, is a cofactor for FGF23-receptor. Circulating soluble-α-Klotho (s-Klotho results from TM-Klotho shedding and acts on Phosphate (P and Calcium (Ca tubular transport. Decreased TM-Klotho, described in experimental chronic kidney disease (CKD, prevents actions of FGF23 and lessens circulating s-Klotho. Thus, levels of s-Klotho could represent a marker of CKD-MBD. To evaluate the clinical significance of s-Klotho in CKD we assayed serum s-Klotho and serum FGF23 in 68 patients (age 58±15; eGFR 45±21 mL/min. s-Klotho was lower than normal (519±183 versus 845±330 pg/mL, P<.0001 in renal patients and its reduction was detectable since CKD stage 2 (P<.01. s-Klotho correlated positively with eGFR and serum calcium (Cas and negatively with serum phosphate (Ps, PTH and FGF23. FGF23 was higher than normal (73±51 versus 36±11, P<.0002 with significantly increased levels since CKD stage 2 (P<.001. Our data indicate a negative effect of renal disease on circulating s-Klotho starting very early in CKD. Assuming that s-Klotho mirrors TM-Klotho synthesis, low circulating s-Klotho seems to reflect the ensuing of tubular resistance to FGF23, which, accordingly, is increased. We endorse s-Klotho as an early marker of CKD-MBD.

    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

    Bischoff-Ferrari, Heike A

    2014-01-01

    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 Design: The genetic predisposition, infectious agents, various antibodies and oxidative stress has been suggested to be among the possible causes of the etiopathogenesis of Behçet’s disease (BD. Recently, a new protein called visfatin, synthesized by adipose tissue has been identified. Visfatin has been found to be associated with many cases like insulin resistance, obesity, atherosclerosis, inflammation, immunity. In this study, we aimed to evaluate the relationship between serum visfatin levels and the activity of Behçet's disease, and determine the role of visfatin in the inflammatory process of BD. Materials and Methods: One hundred patients (43 M, 57 F who were diagnosed as Behçet’s disease according to BD International Working Group criteria and 60 (31 M, 29 F healthy individuals joined the study. Patient group was composed of 50 active and 50 inactive Behçet's patients. Statistical analyzes were performed with SPSS 15.0 program. Results: Visfatin levels were significantly higher in both group of patients compared to the control group (p<0.001 (p<0.001. Serum visfatin levels in patients with active disease were found statistically significantly higher than inactive patients (p<0.001. Conclusions: Serum visfatin levels in both active and inactive patient groups were higher than the control group. Visfatin is a proinflammatory cytokine and has a role in chronic inflammatory reaction by inducing cellular expression of inflammatory cytokines. Visfatin may play a role via this method in the pathogenesis of active and chronic phase of Behcet's disease.

    Full Text Available Serum adrenal androgens (AAs, including androstenedione (Δ4A and dehydroepiandrosterone sulfate (DHEAS, have been reported to be lower in female rheumatoid arthritis (RA patients with early disease. Few data are available on hormonal status of women before the onset of clinical rheumatoid arthritis (pre-RA. A broad baseline panel of serum adrenal and sex steroids was compared in 36 female pre-RA to 144 matched cohort control (CN subjects to determine differences in their mean values and in patterns of hormonal correlations. Study subjects having lower versus higher baseline serum cortisol levels than the total group's mean value were also analyzed separately to investigate differences in their hormonal levels and correlational patterns. In total subjects, mean (±SE Δ4A level (nmol/L was lower (P=0.018 in 28 pre-RA cases (6.4±0.40 versus 108 CN (7.8±0.28. The significant (P=0.013 difference was restricted to 9 pre-RA versus 53 CN subjects having lower cortisol levels (5.6±0.73 versus 8.0±0.42 nmol/L, resp.. In total subjects, no significant difference was found between study subjects in their bivariate correlations of the hormonal panel variables, unlike results found in the subgroups stratified by lower versus higher cortisol levels. A subgroup of pre-RA females may have relative adrenal cortical insufficiency, as reflected by lower Δ4A, especially observed among those subjects with lower cortisol levels.

    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.

    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

  18. 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)

    Full Text Available Objective: Although the diagnosis of patients with severemalnutrition is easy, it is very difficult to recognize patientswith mild and moderate malnutrition. A variety of methodsattempts to develop for early diagnosis of these cases.In this study, we evaluated the serum transferrin and albuminlevels in children with mild, moderate and severeprotein-energy malnutrition (PEM.Materials and methods: Children admitted to our policlinic,aged between 3 and 25 months, 45 subjects withPEM and 39 healthy subjects (control group were evaluated.According to the Gomez, Waterlow and Kanawatisubjects with PEM were divided in 3 subgroups mild,moderate and severe PEM. Anthropometric measurementsand biochemical results of 4 groups were compared.Results: For albumin levels in mild to moderate PEMgroups, 37.7% sensitivity, and 28.5% specificity, positivepredictive value 54%; negative predictive value 16.6%was found. For severe PEM sensitivity, specificity, positivepredictive value and negative predictive value were71%, 62.5%, 45%, and 83.3% respectively.With respect to the levels of transferrin, a significant differencewas found between mild PEM-control and moderatePEM-control groups (p0.05.Conclusion: Our study results showed that albumin isa weak indicator in mild-moderate PEM. In these cases,serum transferrin level reduces before decreasing of albuminlevel, thus it may be an early sensitive finding thatcan be used as a sensitive parameter in the diagnosis ofearly stages of malnutrition.Key words: Protein energy malnutrition, children, albumin,transferrin

    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.

    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

    AIM To report a new method designed to collect gastric juice from chicken, and determine the basal levelof gastric acid and serum gastrin, and the effect of pentagastrin on gastric acid output.METHODS White Leghorn chickens, weighing 1.3 kg- 1.7 kg, deprived of food 24 h prior to experiment,were anaesthetized with pentobarbital sodium (60μg/kg, im). A reverse double lumen perfusion cannulawas introduced into the distal portion of the proventriculus through the crop incision. The perfusate drainedout from the cannular outlet was collected to determine the gastric acid. Gastric acid volume was determinedby titration with 0.01N NaOH. Serum gastrin levels were measured by radioimmunoassay using gastrin assaykit.RESULTS Acid output in the basal state was 0.041±0.006 mmol/L/10min, or 0.246±0.031mmol/L/h. The serum gastrin concentration was 78.27±19.19 pg/mL (n = 22). Three groups wereinjected pentagastrin at three dose level, 20μg/kg, 60μg/kg, 120μg/kg, respectively. The maximumoutput in three groups was 275%, 181% and 167% of their control acid output. Isoproterenol at a dose of0.3 mg/kg produced obvious inhibition of pentagastrin-stimulated gastric secretion. The effect ofisoproterenol on gastric secretion was completely abolished by propranolol, a β-receptor antagonist, but wasnot done by practolol, another 31-receptor antagonist.CONCLUSION The basal gastric acid output of chicken was high. Pentagastrin remarkably stimulatedgastric acid secretion, which could be inhibited by isoproterenol.

    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.

    To investigate the level of serum IL-10 in allergic rhinitis patients and the correlation between IL-10 and serum total IgE (TIgE). 50 allergic rhinitis patients and 30 normal subjects were involved in the study. The levels of serum IL-10 and TIgE were measured by enzyme-linked immunosorbent assay (ELISA), and the correlation between serum IL-10 and TIgE was analyzed. In the allergic rhinitis group, the levels of serum IL-10 and TIgE were 8.34±2.48 pg/mL and 142. 6±28.2 KUA/L. In the normal control group, they were 12. 86±2.88 pg/mL and 47.2±12.2 KUA.There were significant differences between the two groups (P<0.01); and the level of serum TIgE in the patients was negatively correlated with that of IL-10 (r= -0.46, P=0.02). The level of serum IL-10 was significantly decreased in allergic rhinitis patients, which was beneficial to the synthesization of IgE. IL-10 plays an important role in the episode of allergic rhinitis.

  14. The Importance of Serum Cytokine Levels in Febrile Neutropenia

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

    Full Text Available The aims of this study were to compare the hormones and metabolites serum levels and the reproductive performances of nulliparous (n=100 and primiparous pregnant does submitted to artificial insemination (AI 11 days post-partum. On the day of AI, all the does were weighed and the sexual receptivity was evaluated. The kits were weaned at 26 day. Blood samples were collect by punc- ture of the marginal ear vein from one day before AI until few days before the kindling and assayed for hormones and metabolites. The higher sexual receptivity and the fertility in nulliparous than in primiparous does confirmed the negative effect of lactation. Nulliparous does showed higher blood con- centration of leptine than primiparous, and in both the groups such level lowered during pregnancy, probably reflecting the reduction of the fat reserve. The insuline level increased during pregnancy in either groups as a consequence of the growing of the foetuses. In nulliparous does the cortisol, NEFA and T3 concentrations were higher than primiparous does. The glucose levels were similar in both the groups probably due to the homeostatic mechanisms controlling the glycemia. Hormonal and metabo- lite analyses represent a good tool for understanding the physiological mechanisms required to meet higher reproductive performance.

    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 ({omega} - 2, where {omega} is the GPI moiety at E160), P159 ({omega} - 1), and M162 ({omega} + 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.

  18. Serum cortisol level and its correlation to serum insulin and fasting blood sugar levels in patients with type 2 diabetes mellitus

    International Nuclear Information System (INIS)

    Objective: To investigate the change of serum cortisol levels and its correlation to blood sugar and serum insulin levels in patients with type 2 diabetes mellitus. Methods: Blood sugar with oxidase method and serum cortisol insulin levels with RIA (8 AM fasting specimen) were measured in 26 patients with type 2 diabetes mellitus and 30 controls. Results: The serum cortisol levels in the diabetic patients were significantly higher than those in the controls (P<0.01). The cortisol levels were positively correlated to the blood sugar levels (r=0.32, p<0.01), but not correlated to insulin levels. Conclusion: There were cortisol secretion disturbances in patients with type 2 diabetes

    The association of serum trace elements like selenium, zinc and copper has been found in different types of cancer. This study was conducted to see the serum level of these three trace elements in cancer esophagus patients. Biopsy confirmed cancer esophagus, 24 patients (12 males, 12 females, mean age 54.5±11.65 year with 23 healthy subjects (16 males, 7 females, mean age 44 ±13.82 years) were included in this study. Both control and study group patients were of same socio-economic status and dietary habits. Serum zinc and copper level were estimated using standard absorption spectrometer technique and serum selenium by Hydride generation method.We observed significant low serum levels of zinc and selenium while high level of serum copper in carcinoma esophagus patients, as compared with normal healthy controls. This shows an association of serum selenium zinc and copper with cancer esophagus.

    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.

  2. 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

    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.

    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

  6. 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

    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

    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

  10. 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.

    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.

    2014-01-01

    Full Text Available Background: The study assessed whether low maternal serum cholesterol during early pregnancy is associated with preterm delivery. Patients and Methods: It was a prospective observational cohort study involving pregnant women at gestational age of 14-20 weeks over a period of 12 months. Blood samples were obtained to measure total serum cholesterol concentrations and the sera were then analysed enzymatically by the cholesterol oxidase: p-aminophenazone (CHOD PAP method. 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. Conclusion: Low maternal serum cholesterol (hypocholesterolaemia is associated with preterm delivery. Optimal maternal serum cholesterol during pregnancy may have merit, therefore pregnant women should be encouraged to follow a healthy, balanced diet.

    The results analysed showed that there was a clinically significant but statistically non significant reduction in 24hr VAS score in Group I& III patients than Group II patients who had a high oestrogen level. A negative correlation between serum oestrogen and mean duration of analgesia further support this, indicating that low serum oestrogen level decreases pain sensitiv-ity and high serum oestrogen level increases pain sensitivity.

    Chronic mountain sickness (CMS), a lack of adaptation to altitude characterized by excessive erythrocytosis (EE), is a health problem associated with life at high altitude. The erythropoietic process is regulated by both erythropoietin and testosterone. Zinc (Zn) is known to be related with testosterone and hemoglobin levels; meanwhile, nitric oxide was also associated with adaptation to high altitude. The aim of this study was to determine the relationship of hemoglobin and CMS score with serum levels of zinc, total testosterone (TT), calculated free testosterone (cFT), bioavailable testosterone (BAT), hemoglobin, and nitric oxide in men at high altitude with or without EE. Men residing in Lima (150 m) and Cerro de Pasco (4,340 m), Peru, were divided into three groups: (1) low altitude, (2) high altitude without EE (hemoglobin < 21 g/dl), and (3) high altitude with EE (hemoglobin ≥ 21 g/dl). Adjusted multivariable regression models showed that serum testosterone (total or free) and Zn levels were independently correlated with increased hemoglobin levels. Similarly, hemoglobin was positively related with signs/symptoms of CMS; however, both increased the serum Zn and the nitric oxide levels correlated with reduced risk for signs/symptoms of CMS. In conclusion, higher serum testosterone levels and Zn levels were associated with EE, and low scores of signs/symptoms of CMS were associated with higher Zn and nitric oxide levels.

    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.

    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)

  1. Clinical significance of changes of serum leptin and insulin levels in patients with polycystic ovary syndrome

    International Nuclear Information System (INIS)

    Objective: To explore the relationship between the serum leptin, insulin levels and development of polycystic ovary syndrome (PCOS). Methods: Serum leptin and insulin levels (with RIA) were determined in 34 patients with PCOS and 30 controls. Results: The serum leptin and insulin levels in the 34 PCOS patients were significantly higher than those in controls (P<0. 01), and those in obese patients (n=22) were significantly higher than those in non-obese ones (n=12) too(P<0.01). Conclusion: Changes of serum leptin and insulin levels were closely related to the development of PCOS and leptin might be used as a diagnostic indicator for PCOS. (authors)

  2. Serum Macromineral Levels in Estrual, Fertile, Subfertile and Pregnant Mares Kept Under Two Different Managemental Conditions

    2010-04-01

    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.

  3. 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.)

    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.

    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 serum copper (SCL) and zinc (SZL) levels were measured in 99 patients with cervical cancer and 50 patients with uterine myoma as controls. The mean SCL in the control group was 109.4 +/- 17.4 micrograms/ml as compared to 117.1 +/- 14.6 micrograms/dl and was not significant (NS) in 17 carcinoma in situ (CIS) patients, 142.3 +/- 14.2 micrograms/dl in 30 stage I patients (p less than 0.001), 159.0 +/- 16.6 micrograms/dl in 22 stage II patients (p less than 0.001), 171.6 +/- 25.7 micrograms/dl in 10 stage III or IV patients (p less than 0.001), and 166.2 +/- 32.2 micrograms/dl in 20 recurrent patients (p less than 0.001). The SCL returned to control level 2 weeks after surgical treatment for the stage I and II patients (mean 110.6 +/- 19.6 and 108.7 +/- 20.4 micrograms/dl, respectively, p less than 0.001). The SZL was 97.2 +/- 15.8 micrograms/dl in control patients and only showed a significant decrease in stage III or IV and recurrent patients (67.2 +/- 16.6 and 70.4 +/- 17.2 micrograms/dl, respectively). Concerning the copper/zinc ratio, the control group was 1.13 +/- 0.07 as compared to 1.17 +/- 0.07 in CIS (p = 0.06), 1.51 +/- 0.24 in stage I (p less than 0.001), 1.85 +/- 0.37 in stage II (p less than 0.001), 2.66 +/- 0.61 in stage III or IV (p less than 0.001), and 2.50 +/- 0.75 in recurrent patients (p less than 0.001). Taking mean +/- 2.5 SD of the control values as cut off points, the percentages of the recurrent patients with abnormal SCL, SZL, and a Cu/Zn ratio were 65, 30 and 90%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

    Serum and cervical tissue copper (Cu), zinc (Zn) and magnesium (Mg) levels were determined by atomic absorption spectrophotometry in 65 women with cervical carcinoma and compared with levels in 30 healthy women. The patients mean serum Cu level (184.8 +/- 12.3 mugr/dl) was significantly higher than the control group (p cancerous tissues of patients with cervical carcinoma were not statistically significant (p > 0.05). There was also no significant difference between FIGO Stage I and IIA patients according to their serum and tissue concentrations of these trace elements. We concluded that serum and tissue copper, zinc and magnesium determinations have no use in cervical carcinoma management.

    Full Text Available High-altitude deacclimatization syndrome (HADAS is emerging as a severe public health issue that threatens the quality of life of individuals who return to lower altitude from high altitude. In this study, we measured serum levels of SOD, MDA, IL-17A, IL-10, TNF-α, and HADAS score in HADAS subjects at baseline and 50th and 100th days and to evaluate the relationship between interleukins, including IL-17A, and HADAS. Our data showed that and the serum IL-17A levels and HADAS score decreased over time in the HADAS group, and serum IL-17A levels were significantly higher in the HADAS group at baseline and 50th day compared with controls (p<0.05. Furthermore, baseline serum levels of MDA and TNF-α were significantly higher, while SOD and IL-10 levels were lower in HADAS subjects compared with controls (p<0.05. It is interesting that serum levels of IL-17A were clearly interrelated with HADAS incidence and severity (p<0.05. ROC curve analysis showed that combined serum IL-17A and IL-10 levels were a better predictor of HADAS incidence than serum levels of IL-17A or IL-10 alone. These data suggest that serum levels of IL-17A are a novel predictive index of HADAS.

    Wnt-β-catenin signaling is important for bone formation. Sclerostin inhibits bone formation mainly by suppressing this signal, and several studies suggest that the suppression of sclerostin expression contributes to the bone anabolic action of parathyroid hormone (PTH). We therefore examined serum sclerostin levels using enzyme-linked immunosolvent assay in 18 patients with postmenopausal osteoporosis, 9 postmenopausal women with primary hyperparathyroidism (pHPT) and 7 patients with osteomalacia. Serum levels of sclerostin were significantly lower in the group with pHPT, compared with those with postmenopausal osteoporosis. Moreover, serum sclerostin levels were significantly lower in the group with tumor-induced osteomalacia, but not in the group with osteomalacia without tumor, compared with those with postmenopausal osteoporosis. In patients with pHPT, serum sclerostin levels were significantly and negatively correlated to serum calcium and PTH levels. In patients with postmenopausal osteoporosis, serum levels of sclerostin levels were significantly and positively related to serum calcium and creatinine levels. In conclusion, we showed that serum sclerostin levels are decreased presumably through endogenous PTH elevation in postmenopausal women with pHPT, compared with the patients with postmenopausal osteoporosis.

    Objective: To explore the serum level changes of parathyroid hormone (PTH) and Calcitonin (CT) in hyperthyroid-and hypothyroid-patients. Methods: Serum parathyroid hormone and Calcitonin levels were determined With RIA in 62 cases of hyperthyroidism, 32 cases of hypothyroidism and 35 normal Controls. Results: The serum PTH levels in patients with hyperthyroidism were lower than those in controls (P < 0.05); the PTH levels in patients with hypothyroidism were high than normal (P < 0.01). The serum CT levels were decreased both in hyperthyroid and hypothyroid patients (P < 0.01). Conclusion: Determination of changes of serum PTH and CT levels in hyperthyroidism and hypothyroidism was of important clinical Significance

  15. 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

  18. Relationship of serum and seminal plasma zinc levels and serum testosterone in oligospermic and azoospermic infertile men

    International Nuclear Information System (INIS)

    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

  1. 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.

    Full Text Available Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008. Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008. Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

    Preclinical and clinical studies show associations between testosterone and brain-derived neurotrophic growth factor (BDNF) serum levels. BDNF and testosterone have been independently reported to influence alcohol consumption. Therefore, we aimed to investigate a possible interplay of testosterone and BDNF contributing to alcohol dependence. Regarding possible interplay of testosterone and BDNF and the activity of the hypothalamic pituitary axis (HPA), we included cortisol serum levels in our research. We investigated testosterone and BDNF serum levels in a sample of 99 male alcohol-dependent patients during alcohol withdrawal (day 1, 7, and 14) and compared them to a healthy male control group (n = 17). The testosterone serum levels were significantly (p < 0.001) higher in the patients' group than in the control group and decreased significantly during alcohol withdrawal (p < 0.001). The decrease of testosterone serum levels during alcohol withdrawal (days 1-7) was significantly associated with the BDNF serum levels (day 1: p = 0.008). In a subgroup of patients showing high cortisol serum levels (putatively mirroring high HPA activity), we found a significant association of BDNF and testosterone as well as with alcohol craving measured by the Obsessive and Compulsive Drinking Scale (OCDS). Our data suggest a possible association of BDNF and testosterone serum levels, which may be relevant for the symptomatology of alcohol dependence. Further studies are needed to clarify our results.

    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

    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

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

    High-altitude deacclimatization syndrome (HADAS) is emerging as a severe public health issue that threatens the quality of life of individuals who return to lower altitude from high altitude. In this study, we measured serum levels of SOD, MDA, IL-17A, IL-10, TNF-α, and HADAS score in HADAS subjects at baseline and 50th and 100th days and to evaluate the relationship between interleukins, including IL-17A, and HADAS. Our data showed that and the serum IL-17A levels and HADAS score decreased over time in the HADAS group, and serum IL-17A levels were significantly higher in the HADAS group at baseline and 50th day compared with controls (p HADAS subjects compared with controls (p HADAS incidence and severity (p HADAS incidence than serum levels of IL-17A or IL-10 alone. These data suggest that serum levels of IL-17A are a novel predictive index of HADAS.

    Prostate cancer is one of the most common cancers in men. Traditional screening and diagnostic methods include digital rectal examinations(DREs), biopsies and serum prostate‑speciifc antigen(PSA) tests, with the latter being the more popular. PSA is a biomarker for prostate cancer; however, it is highly sensitive to external factors as well as other prostate diseases. As such, the reliability of of the serum PSA level as a sole screening and diagnostic tool for prostate cancer is controversial. Recently, it has been shown that fasting extremes can affect concentrations of serum chemistry analytes, thus raising the question of whether or not fasting has an effect on the highly sensitive PSA biomarker. Patients testing for serum PSA levels are often concomitantly submitting to other tests that require fasting, subjecting certain patients to a fasting PSA level while others not. The objective of this study was to investigate whether this discrepancy in fasting state translates into an effect on serum PSA levels. Serum PSA levels and fasting time records for 157276 men who underwent testing at Calgary Laboratory Services(CLS; Calgary, Alberta, Canada) between 01January 2010 and 31March 2013 were accessed. Linear regression models of mean PSA levels and fasting times revealed a statistically important relationship at certain fasting times. Applying a dynamic mathematical model to explore the clinical effect of fasting suggests minimal impact on serum PSA result interpretation. Thus, patients can be tested for serum PSA levels regardless of their fasting state.

    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.

  14. 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.

    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.

    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.

  7. 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

    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 Background: Inadequate milk intake during the first year of neonate’s life can result in weight loss, severe hyperbilirubinemia, and sometimes hypernatremia. In this study, we aimed to determine the relationship between neonatal weight loss and hypernatremia in term breastfed infants with idiopathic jaundice, as well as the necessity of sodium concentration measurement in newborns with idiopathic jaundice via weight loss measurement. Methods: In this cross-sectional study, we examined 273 infants with jaundice of unknown etiology at Ghaem Hospital, Mashhad, in years 2008-2012. The study sample consisted of 226 infants in the control group (serum sodium concentration

    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.

  12. Study on the relationship between the serum adiponectin and insulin levels in patients with polycystic ovary syndrome (PCOS)

    International Nuclear Information System (INIS)

    Objective: To study the relationship between the serum adiponectin and insulin levels in patients with polycystic ovary syndrome (PCOS). Methods: Levels of serum adiponectin and insulin were detected with RIA in 36 patients with polycystic ovary syndrome and 35 controls. Results: In the patients, the serum adiponectin levels were significantly lower than those in controls (P <0.01), while the serum insulin levels were significantly higher (P <0.01). Serum adiponectin and insulin levels were mutually negatively correlated (r =-0.5034, P < 0.01). Conclusion: There is a close relationship between the serum adiponectin and insulin levels in patients with polycystic ovary syndrome. (authors)

  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.

    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.

    Full Text Available BACKGROUND: Cholesterol, in the form of bile salts, is reabsorbed from the small intestine via the enterohepatic circulation. Biliary sphincterotomy increases the delivery of bile to the terminal ileum. If the absorptive capacity is exceeded, cholesterol excretion may increase, resulting in a decrease in serum cholesterol levels and improvement in serum lipid profiles.

    This study was conducted to evaluate the possible alteration of serum Cu and Zn levels in 118 medical inpatients (53 women and 65 men) in Ramathibodi Hospital. Patients were classified according to their main clinical diseases: pulmonary (n = 12), renal (14), infectious (30), malignant (9), cardiovascular (22), GI & hepatic (13) and hematological (18) diseases. Significantly increased serum Cu concentrations were found in patients with pulmonary, malignant, cardiovascular and infectious diseases; moreover, 75, 75, 50 and 37 per cent of these diseases, respectively, had serum levels greater than the normal mean + 2SD (23.6 mumol/L). Besides, 5 per cent of patients (3 in renal, 1 in infectious and 2 in GI & hepatic diseases) had low serum Cu levels suggestive of Cu depletion. By contrast, significantly decreased serum Zn concentrations were found in patients with GI & hepatic, infectious, renal, cardiovascular and malignant diseases. Serum Zn levels below the normal mean - 2SD (8.1 mumol/L) were presented in 46, 37, 29, 23 and 22 per cent of cases, respectively. It was found that serum Cu/Zn ratio in our patients not only with cancer but also with other diseases were statistically significant from the normal group. Hence, the use of serum Cu/Zn ratios as markers for the diagnosis of cancer or for staging tumors must be interpreted cautiously.

    Full Text Available Background: Apart from the crucial role of micronutrients like copper, iron, and zinc in the functions of body enzymes, it seems that changes in the serum levels of these biomarkers may play a role in the pathogenesis of oral cancer. The aim of this study was to measure the serum levels of ferritin, copper, and zinc in patients with oral malignancies. Methods: Sixty consecutive patients with oral cancer, together with 66 age- and sex-matched controls were enrolled in this cross-sectional study. The serum levels of ferritin, copper, and zinc were measured in both patients and healthy individuals. Data were statistically analyzed by Student's t-test and Mann-Whitney U test. Results: In patients with oral cancer, the serum levels of ferritin, copper, and zinc were 267.41 ± 249.45, 209.85 ± 160.28, and 113.51 ± 52.30 mg/dl, respectively. In the control group, the serum levels of ferritin, copper, and zinc were reported to be 106.13 ± 72.96, 114.20 ± 38.69, and 64.57 ± 31.54 mg/dl, respectively. The mean serum values of ferritin, copper, and zinc in cancerous patients were significantly higher than in controls (p < 0.001. Conclusions: The serum levels of ferritin, copper, and zinc in oral cancer patients were significantly higher than in control group subjects.

    1990-01-01

    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.

    Yoshifumi Amari

    Full Text Available The (prorenin receptor [(PRR] is cleaved by furin to generate soluble (PRR [s(PRR], which reflects the status of the tissue renin-angiotensin system. Hemodialysis patients have advanced atherosclerosis. The aim of this study was to investigate the relationships between serum s(PRR levels and background factors, including indices of atherosclerosis, in hemodialysis patients. Serum s(PRR levels were measured in hemodialysis patients and clearance of s(PRR through the membrane of the dialyzer was examined. Furthermore, relationships between serum s(PRR levels and background factors were assessed. Serum s(PRR levels were significantly higher in hemodialysis patients (30.4 ± 6.1 ng/ml, n = 258 than those in subjects with normal renal function (21.4 ± 6.2 ng/ml, n = 39, P < 0.0001. Clearance of s(PRR and creatinine were 56.9 ± 33.5 and 147.6 ± 9.50 ml/min, respectively. Serum s(PRR levels were significantly higher in those with ankle-brachial index (ABI of < 0.9, an indicator of severe atherosclerosis, than those with ABI of ≥ 0.9 (32.2 ± 5.9 and 30.1 ± 6.2 ng/ml, respectively, P < 0.05. An association between low ABI and high serum s(PRR levels was observed even after correction for age, history of smoking, HbA1c, and LDL-C. Serum s(PRR levels were significantly higher in hemodialysis patients when compared with subjects with normal renal function, although s(PRR is dialyzed to some extent, but to a lesser extent than creatinine. High serum s(PRR levels may be associated with atherosclerosis independent of other risk factors, suggesting that serum s(PRR could be used as a marker for atherosclerotic conditions in hemodialysis patients.

    International Nuclear Information System (INIS)

    Objective: To investigate the importance of determination of changes of serum procalcitonin (PCT) and IL-6 levels in patients with sepsis. Methods: Serum PCT (with double-sandwich immunofluorescence assay) and IL-6 (with ELISA) levels were measured repeatedly in 130 patients with sepsis on d1, d3, d5, d7 after admission. Values in 130 healthy individuals were also measured as control. Results: The serum levels of PCT and IL-6 in the patients with sepsis of admission were significantly higher than those in controls. The levels dropped markedly in the survivors by d7. Among the septic patients, the levels in the succumbed patients were significantly higher those in the survivors (P<0.05). Conclusion: Serum PCT and IL-6 values appeared to be of prognostic value in patients with sepsis. (authors)

    Full Text Available The objective of the study is to evaluate the relationship between serum testos-terone levels and cardiovascular risk factors (CVRF in patients after kidney transplantation and with chronic kidney disease (CKD. Seventy-five male patients, aged between 18 and 68 years, who had kidney transplantation at least six months earlier, were enrolled into the study. Only renal transplant recipients and CKD patients with a creatinine level of 0.05. Serum testosterone levels were independent risk factors affecting IVC collapse index, systolic BP and LA. m-TORi and CNIs drugs might have no negative effect on serum testosterone levels, and improvement of the serum testosterone levels after transplantation might have a positive contribution on cardiac risk factors.

  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)

  15. The relation between serum phosphorus levels and clinical outcomes after acute myocardial infarction.

    Directory of Open Access Journals (Sweden)

    Doron Aronson

    Full Text Available BACKGROUND: Elevated serum phosphorus levels have been linked with cardiovascular disease and mortality with conflicting results, especially in the presence of normal renal function. METHODS: We studied the association between serum phosphorus levels and clinical outcomes in 1663 patients with acute myocardial infarction (AMI. Patients were categorized into 4 groups based on serum phosphorus levels (4.50 mg/dL. Cox proportional-hazards models were used to examine the association between serum phosphorus and clinical outcomes after adjustment for potential confounders. RESULTS: The mean follow up was 45 months. The lowest mortality occurred in patients with serum phosphorus between 2.5-3.5 mg/dL, with a multivariable-adjusted hazard ratio of 1.24 (95% CI 0.85-1.80, 1.35 (95% CI 1.05-1.74, and 1.75 (95% CI 1.27-2.40 in patients with serum phosphorus of 4.50 mg/dL, respectively. Higher phosphorus levels were also associated with increased risk of heart failure, but not the risk of myocardial infarction or stroke. The effect of elevated phosphorus was more pronounced in patients with chronic kidney disease (CKD. The hazard ratio for mortality in patients with serum phosphorus >4.5 mg/dL compared to patients with serum phosphorus 2.50-3.50 mg/dL was 2.34 (95% CI 1.55-3.54 with CKD and 1.53 (95% CI 0.87-2.69 without CKD. CONCLUSION: We found a graded, independent association between serum phosphorus and all-cause mortality and heart failure in patients after AMI. The risk for mortality appears to increase with serum phosphorus levels within the normal range and is more prominent in the presence of CKD.

  16. Relationships between serum osteoprotegerin, matrix metalloproteinase-2 levels and bone metabolism in postmenopausal women

    2007-01-01

    Background Serum osteoprotegerin (OPG) and matrix metalloproteinase-2 (MMP-2) have been shown to play a role in bone metabolism by degrading the bone matrix. The present study was undertaken to compare OPG and MMP-2 with bone mineral density and three markers (alkaline phosphatase (AKP), calcium and phosphorus) in postmenopausal women in Wuhan.Methods Serum OPG, MMP-2, and AKP of 78 Chinese postmenopausal women aged 48 to 65 were measured using enzyme-linked immunosorbent assay (ELISA). Bone mineral density was measured with dual energy X-ray absorptiometry (DEXA), and serum calcium and phosphorus were measured by auto biochemical analysis.Results Serum OPG and MMP-2 concentrations were significantly higher in postmenopausal women with osteoporosis ((127.6±6.3) ng/L; (1388±121) μg/L)) than those in age-matched normal controls ((72.3±2.4) ng/L; (1126±141) μg/L,P<0.01). Negative relationships were found between serum OPG, MMP-2 levels and bone mineral density in osteoporotic women. Adjusted by age and body mass index (BMI), the correlation of MMP-2 with bone mineral density of the neck of the femur disappeared. In osteoporotic women, negative correlations between OPG, MMP-2 levels and serum calcium were found (r=-0.216; r=-0.269, P<0.05), but positive correlations between OPG and serum AKP, serum phosphorus (r=0.235; r=0.124, P<0.05).Conclusions Significant correlations exist between serum OPG, MMP-2 levels and bone metabolism in high bone turnover of postmenopausal osteoporotic women. The concentrations of serum OPG and MMP-2 increase possibly as a concomitant event in the high bone turnover state, such as postmenopausal osteoporosis. Therefore serum OPG and MMP-2 could be used as indicators for the bone metabolism in postmenopausal osteoporotic women.

    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 Introduction & Objective: High levels of homocystein are a risk factor for insulin resistance, diabetes mellitus and cardio-vascular complications. This study was done to assess serum homocystein and folic acid levels and their relationship in women with gestational diabetes and compare them with normal pregnant women. Materials & Methods: This analytic epidemiologic case-control study was performed in Qazvin Kosar hospital in 2013-2015. 120 singleton pregnant women with 24-28 weeks of gestation according to 2-hour 75g oral glucose tolerance test were assigned to two groups; gestational diabetes (n=60, and normal pregnancy (n=60. Serum homocystein and folic acid levels were measured in two groups. Data were analyzed with statistical t-test and correlation method. Results: In gestational diabetes serum homocystein level was significantly higher (P<0.001 and folic acid was significantly lower (P<0.001 than normal pregnancy group .No relation-ship was observed between serum homocystein and serum folate. In both groups, serum folic acid was significantly related to fasting blood sugar. This relationship was inverse in gesta-tional diabetes group (P<0.001, r = - 0.512 and direct in normal pregnancy group (P=0.001 r =0.417. Conclusion: It seems folic acid has a role in regulation of serum homocystein level and blood sugar.(Sci J Hamadan Univ Med Sci 2015; 22 (2: 93-98

    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

    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.

    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 Alzheimer's disease is the most common dementia in the elderly, and the potential of peripheral biochemical markers as complementary tools in the neuropsychiatric evaluation of these patients has claimed further attention. Methods We evaluated serum levels of S100B and neuron-specific enolase (NSE in 54 mild, moderate and severe Alzheimer's disease (AD patients and in 66 community-dwelling elderly. AD patients met the probable NINCDS-ADRDA criteria. Severity of dementia was ascertained by the Clinical Dementia Rating (CDR scale, cognitive function by the Mini Mental State Examination (MMSE, and neuroimage findings with magnetic resonance imaging. Serum was obtained from all individuals and frozen at -70°C until analysis. Results By comparing both groups, serum S100B levels were lower in AD group, while serum NSE levels were the same both groups. In AD patients, S100B levels were positively correlated with CDR scores (rho = 0.269; p = 0.049 and negatively correlated with MMSE scores (rho = -0.33; P = 0.048. NSE levels decreased in AD patients with higher levels of brain atrophy. Conclusions The findings suggest that serum levels of S100B may be a marker for brain functional condition and serum NSE levels may be a marker for morphological status in AD.

    Paragonimiasis is a parasitic pleuropulmonary infection caused by eating raw crustaceans and wild boar meat and this infection is endemic in Asia. We herein report two cases of pulmonary Paragonimus westermani infection associated with elevated levels of serum immunoglobulin (Ig) G4 and dense infiltration of IgG4-positive plasma cells in the lung lesions. Treatment with praziquantel resolved the pulmonary lesions and decreased the serum levels of IgG4. IgG4-related disease is a systemic disease occasionally involving the lungs and leads to increased serum levels of IgG4. Our findings suggest that P. westermani infection requires a differential diagnosis from IgG4-related diseases and the serum IgG4 level may be a potentially useful marker of P. westermani infection.

    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.

    Full Text Available Serum carbohydrate antigen 19-9 (CA 19-9, a marker of malignant tumors, is generally slightly elevated in benign conditions. We report a case of acute cholecystitis with a significantly elevated level of serum CA 19-9 based on positron emission tomography (PET-computed tomography (CT findings. A 65-year-old woman presented with abdominal pain and fever. A CT image revealed an enlarged gallbladder without tumor shadows. The C-reactive protein (CRP level was elevated to 7.66 mg/dl. Moreover, the serum CA 19-9 level was significantly elevated to 19,392 U/ml. We started antibiotic treatment, because we suspected acute cholecystitis, but still, we could not ignore the possible presence of malignant tumors. After 11 days of antibiotic treatment, serum CRP and CA 19-9 levels decreased to 0.11 mg/dl and 1,049 U/ml, respectively. There was an accumulation of fluorine 18-labeled fluorodeoxyglucose (maximum standardized uptake value, 9.3 without tumor shadows in the liver, near the gallbladder, on the PET-CT examination. We considered the possibility that the inflammation had spread from the gallbladder to the liver, made a diagnosis of acute cholecystitis, and performed a cholecystectomy 33 days after treatment initiation. The serum CA 19-9 level decreased to 45 U/ml after the surgery. One year after the surgery, the patient was alive, and the serum CA 19-9 level was 34 U/ml. Acute cholecystitis with a significantly high elevation of the serum CA 19-9 level is rare. In such cases, it is important to confirm the change in the serum CA 19-9 level over time after antibiotic treatment and perform imaging studies to distinguish between inflammation and malignancy.

    1987-12-01

    Previous studies have suggested that sex steroids, including both oestrogen and testosterone, influence calcitonin secretion. However, a negative effect of gonadotrophins on calcitonin has not been excluded. Twelve men with infertility and low-normal serum levels of testosterone were studied before and during tamoxifen therapy. Increases in the serum levels of LH, FSH, testosterone and calcitonin were observed after treatment. Our findings suggest that testosterone has a direct influence on calcitonin secretion.

    Preclinical studies indicate that brain-derived neurotrophic factor (BDNF) is involved in neuroplastic changes underlying enduring cocaine-seeking following withdrawal. However, little is known about temporal changes in serum BDNF levels or the involvement of BDNF in craving and abstinence in early-abstinent cocaine-dependent patients. Twenty-three cocaine-dependent individuals (aged 33.65 ± 6.85 years) completed a two-week detoxification program at an inpatient facility. Two serum samples were collected for each patient at baseline and at the end of the protocol. Serum samples were also collected for 46 healthy controls (aged 35.52 ± 9.37 years). Demographic, consumption and clinical data were recorded for all patients. Significantly lower serum BDNF levels (p<.0001) were observed for cocaine-dependent patients at baseline compared to healthy controls. Serum BDNF levels increased significantly across 12 days of early abstinence (p=.030). Baseline BDNF levels correlated with craving (p=.034). Post-detoxification BDNF levels correlated with craving (p=.018), loss of control (p<.000), abstinence measures (p=0.031), depression (p=0.036), and anxiety (p=0.036). Post-detoxification BDNF levels also had predictive value for the loss of control measure of craving. Chronic cocaine use is associated with decreased serum BDNF. A progressive increase in serum BDNF levels during early abstinence correlates with cocaine craving and abstinence symptoms and may reflect increasing BDNF levels in different brain regions. These findings suggest that serum BDNF may be a biomarker for cocaine addiction. PMID:23021567

    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.

    The adipocytokine leptin is a key mediator of energy homeostasis. Recent papers have suggested that leptin may also have roles in the brain however it is unclear whether leptin is connected to symptoms of mental disorders. In this study, we sought to clarify the relationships between serum leptin level and psychopathology in schizophrenia (SZ) patients. The severity of positive symptoms inversely correlated with the serum leptin levels among SZ patients. There was no correlation between lepti...

    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 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.

    Objective:To investigate serum levels of MMP-2,MMP-9, oxidized low density lipoprotein (ox-LDL) in Alzheimer's disease (AD) patients and study the possible pathway and mechanism of AD with abnormal lipid metabolism. Methods: Subjects in this study were divided into 4 groups: normal lipid group without AD (N), hyperlipoidemia group without AD (H), normal group with AD (A), hyperlipoidemia group with AD (AH). There were 15 individuals in each group. MMP-2, MMP-9, ox-LDL was measured by enzyme linked immunosorbent assay (ELISA). Serum lipids levels were measured by biochemical methods. Results: The serum levels of MMP-2, MMP-9, ox-LDL were significantly higher in H, A and AH groups than those in N group. Those of ox LDL in H, AH groups was higher than that of in A group. The serum level of MMP-2, MMP-9 in AH groups were higher than that of in H group. The score of mini-mental state examination (MMSE) in A and AD groups was negatively correlated with the serum level of ox-LDL. Relationship between the score of MMSE and the serum level of ox-LDL in AD groups and non-AD groups had statistical significance. Conclusion: MMP-2, MMP-9, ox-LDL and abnormal lipid metabolism may participate in pathogenesis of AD, in which abnormal lipid metabolism induces expressions of MMP-2,MMP-9 and ox-LDL. Oxidative stress and blood-brain barrier disruption might accelerate the process of AD.

    Full Text Available Background. Serum magnesium levels affect the concentration of circulating vitamin D in blood and subsequently it affects the immunity; thus it plays significant role in the pathogenesis of asthma. Asthma, in adults, is less studied and hypomagnesemia along with vitamin D deficiency and insufficiency is common in asthmatic individuals, which causes frequent asthma attacks, respiratory infections, severe exacerbations, and poor response to bronchodilators. Objective. To detect the magnitude of vitamin D insufficiency and deficiency and serum magnesium levels among asthmatic patients and to correlate them with the severity of asthma. Materials and Methods. This is a cross-sectional case-control study which includes 60 patients of chronic stable asthma and 60 healthy controls. After taking clinical history and systemic examination, pulmonary function test was done. Serum levels of magnesium, 25-hydroxycholecalciferol [25(OHD], and calcium were measured in all the subjects. Results. Significant correlation was found between vitamin D deficiency, hypomagnesemia, and asthma severity. Serum calcium levels were unaffected by that. Conclusion. Vitamin D and serum magnesium deficiency are highly prevalent in patients with asthma. Increased asthma severity, frequency of attacks, and exacerbation are associated with lower levels of one or both. Serum 25(OHD and magnesium levels may serve as important markers of asthma severity.

    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.

    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 activi...

    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

    2008-01-01

    Full Text Available Serum and ascitic fluid superoxide dismutase (SOD and malondialdehyde (MDA levels were measured in 43 patients with cirrhosis and in a 10 healthy control group. Compensated cirrhotic patients had no clinically detectable ascites, but decompensated patients had massive ascites. Cirrhotic patients were divided into three groups: patients with compensated cirrhosis (n = 16, patients with decompensated cirrhosis with Spontaneous bacterial peritonitis (SBP (n = 14, and patients with decompensated cirrhosis without SBP (n = 13. All cirrhotic patients in the experimental group had significantly higher serum SOD (p 0.05. These results suggest that the increase in serum SOD and MDA levels are not related to the presence of SBP and the status of liver cirrhosis. To sum up, clarifying the impact of increased serum SOD and MDA levels in cirrhotic patients needs further investigation.

  19. Evaluation of determining serum α1-microglobulin level for early diagnosis of the diabetic retinopathy

    International Nuclear Information System (INIS)

    The serum α1-MG, β2-MG and other indices of 35 patients with NIDDM and 15 patients with diabetic retinopathy are determined. The results show that not only the serum α1-MG, β2-MG of all patients are obviously higher than the normal, but the serum α1-MG rises earlier than β2-MG. By means of correlation analysis, the serum β2-MG is significantly correlative with β2-MG and Scr(r = 0.673, r = 0.608). All those indicate that the level of the serum α1-MG may be a reliable and sensitive index to the diabetic retinopathy in the early diagnosis

    Full Text Available Transforming growth factor-beta1 (TGF-β1, a multi-functional cytokine, is involved in regulating a variety of cellular activities and the serum/plasma TGF-β1 level is altered with various diseases. However, most published reports have described adult patients, and so we investigated the clinical significance of serum TGF-β1 level in pediatric patients. The diagnostic application of the measurement of serum TGF-β1 level depends critically on the control value, however, there is no information on the control value of serum TGF-β1 for children.

    Full Text Available Background: Smoking plays a key role in increasing the inflammatory marker C-reactive protein (CRP. Aims: To examine inverse correlation between CRP and magnesium levels in smokers and nonsmokers. Materials and Methods: A total of 192 healthy adult male subjects were included in the present study, out of which 96 were smokers and the remaining 96 were nonsmokers having age range from 20 to 40 years, and all the subjects belonged to District Matyari of Hyderabad. Serum CRP was measured by NycoCard standard kit method and magnesium levels by DiaSys standard kit method in smokers and nonsmokers. Results: The levels of serum CRP in smokers (14.62 ± 0.16 mg/L is high as compared to nonsmokers (4.81 ± 0.38 mg/L, which is highly significant (P < 0.001. However, inverse results were seen for serum magnesium levels which were significantly higher (P < 0.001 in nonsmokers (2.52 ± 0.18 mg/L as compared to the smokers (1.09 ± 0.38 mg/dL. A significant (P < 0.001 inverse relationship between serum CRP and magnesium concentrations were seen in smokers. Conclusion: This result shows that smoking increases serum CRP, an inflammatory marker parallel to decrease in serum magnesium levels in smokers having 20-40 years of age.

    Sclerostin has been proposed as a potent inhibitor of bone formation. Sclerostin antibodies are under clinical development to treat osteoporosis and metastatic bone disease. Serum sclerostin level is elevated in multiple myeloma, an osteolytic malignancy, where it might serve as predictive marker for the use of sclerostin-directed antibodies. As renal cell carcinoma (RCC) patients often present with osteolytic metastases, we aimed to investigate serum sclerostin levels in RCC patients. Our study included 53 RCC patients (19 with bone metastases, 25 with visceral metastases and 9 with localized disease) and 53 age- and gender-matched non-osteoporotic controls. Frozen serum samples were subjected to sclerostin quantitative sandwich ELISA. The mean serum sclerostin levels of RCC patients and controls were 45.8 pmol/l and 45.1 pmol/l, respectively (p = 0.86). Analysis of variance showed no difference between the subgroups of RCC patients with regard to visceral or bone metastases or localized disease (p = 0.22). There was no significant association between eGFR (estimated glomerular filtration rate) and serum sclerostin levels in RCC patients (r = 0.05; p = 0.74) and controls (r = 0.06; p = 0.68). Our results indicate that serum sclerostin levels appear not to be a valuable biomarker to assess the occurrence of bone metastases in RCC patients. PMID:27666393

    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.

    We studied the serum estradiol and estrone levels in 146 peri and postmenopausal women, and in 38 women who had complained of various climacteric disturbance symptoms during daily hormone replacement therapy (HRT) with conjugated equine estrogen (CEE) 0.625 mg and medroxyprogesterone acetate (MPA) 2.5 mg. Serum estradiol and estrone were measured before treatment, and at 6 months, and after one year of the HRT therapy by HPLC-radioimmunoassay. 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 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.

    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.

    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.

    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.

    To examine daily changes in blood hormone levels during the postpartum period, twenty steroids including free and conjugated pregnenolone (P5), 16 alpha OH-P5(16P5), dehydroepiandrosterone (DHA), 16 alpha OH-DHA(16DHA), estrone(E1), estradiol(E2), estriol(E3), estetrol(E4) and free progesterone(P4), 16 alpha OH - P4(16P4), 20 alpha-dihydro-P4(20P4) and cortisol(F) were measured simultaneously by RIA. Seven patients who delivered a healthy child vaginally were selected for this study. The steroid levels in maternal blood were measured daily until the 7th post partum day and were compared to those at delivery. Levels of free and conjugated E1, E2, P5, free E3 and 16P4 dropped rapidly within 24 hours and reached approximately 10% of those at delivery. Conjugated E2, E4, 16P5, and P4, 20P4 levels also dropped after delivery to less than 17% of those at delivery within 72 hours. However, the levels of these steroids were maintained at more than 20% of those at delivery until the 7th postpartum day. These results provide further information on the significance of the steroids in maternal blood during pregnancy. PMID:6226753

    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.

    This study was aimed to evaluate the relationship between serum interleukin-23 (IL-23) levels and ankylosing spondylitis (AS).Twenty male patients diagnosed with ankylosing spondylitis according to the 1984 modified New York criteria for AS and twenty male healthy controls were included in this study.The demographic characteristics, clinical and laboratory findings of the patients were recorded. Serum IL-23 levels, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured in both the AS and control groups. The Bath ankylosing spondylitis disease activity ındex (BASDAI), the Bath ankylosing spondylitis functional index (BASFI), and the Bath ankylosing spondylitis metrology index (BASMI) were evaluated as disease activity parameters. The AS patients were divided into two subgroups as active and inactive in respect of CRP, ESR levels and BASDAI scores. The mean serum IL-23 levels of the AS and control groups were 334.45±176.54 pg/ml and 166.49±177.50 pg/ml respectively, and there was a significant difference between the groups. Correlation analysis of serum IL-23 levels with clinical and laboratory parameters showed that there were positive correlations between serum IL-23 levels and the BASDAI, BASFI scores in total, active and inactive patients and the BASMI scores in total and inactive patients and negative correlations between serum IL-23 levels and ESR in inactive patients. It was shown that altered serum IL-23 levels were related to AS disease activity. Further studies in large patient series are necessary to investigate the role of IL-23 protein in etiopathogenesis of AS.

    Full Text Available An elevated serum phosphorus (P has been anecdotally described in premature infants receiving human milk fortified with donor human milk-derived fortifier (HMDF. No studies have prospectively investigated serum P in premature infants receiving this fortification strategy. In this single center prospective observational cohort study, extremely premature infants ≤1250 grams (g birth weight (BW were fed an exclusive human milk-based diet receiving HMDF and serum P levels were obtained. We evaluated 93 infants with a mean gestational age of 27.5 ± 2.0 weeks (Mean ± SD and BW of 904 ± 178 g. Seventeen infants (18.3% had at least one high serum P level with a mean serum P of 9.2 ± 1.1 mg/dL occurring at 19 ± 11 days of life. For all infants, the highest serum P was inversely correlated to the day of life of the infant (p < 0.001, R2 = 0.175 and positively correlated with energy density of HMDF (p = 0.035. Serum P was not significantly related to gender, BW, gestational age, or days to full feeds. We conclude that the incidence of hyperphosphatemia was mild and transient in this population. The risk decreased with infant age and was unrelated to gender, BW, or ethnicity.

    2013-08-01

    Full Text Available Introduction: Apart from glucose, insulin release is stimulated or suppressed by some hormones and neural signs. Ghrelin is a gut hormone that stimulates growth hormone (GH secretion, and recent studies have suggested its role in insulin secretion. The objective of this study was to determine baseline insulin’s relationship to ghrelin and GH concentration in asthma males. Methods: In this study, we measured the baseline blood levels of serum ghrelin and GH in adult obese males with mild to moderate asthma and assessed their relationship with serum insulin and pancreatic beta- cell function. Pearson correlation analysis was used to determine the relationship between insulin and other variables. Results: A significant negative correlation was found between fasting serum insulin and both ghrelin and GH concentration. In addition, there was a significant negative correlation between the beta- cell function and both serum ghrelin and GH (P<0.05. Conclusion: Our study findings demonstrated that in adult asthma patients, an increase in serum ghrelin and GH is accompanied by a decrease in serum insulin secretion, and the measuring of serum ghrelin or GH is a predictor of blood insulin level in these patients.

    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.

    Objective: To investigate the changes of serum inhibin B (inhibin. INH-B) levels in women with polycystic ovary syndrome (PCOS) and the relationship with body mass index (BMI). Methods: Serum insulin-like growth factor-I (IGF-I), fasting insulin (In), and leptin ( with RIA) inhibin B (INH-B) (with ELISA) and luteinizing hormone (LH), follicle-stimulating hormone (FSH), human prolactin (PRL), estradiol (E2) testosterone (T) (with CLIA) levels were measured in 40 patients with PCOS and 40 controls. 24 of the 40 PCOS patients were of the obese group (BMI>25) and 16 were non-obese. Results: Serum leptin, In, LH, T levels were significantly higher but INH-B, IGF levels were significantly lower in obese group than those in non-obese group (P<0.05). There were negative correlations between LH and INH levels (r=-0.730, P<0.05 in obese group but none in non-obese group serum). INH-B, IGF, LH, T levels in non-obese group were significantly higher than those in the controls (P<0.05). Conclusion: Inhibin is closely related to the development of PCOS, the level of serum inhibin is lower in obese patients with PCOS. (authors)

    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.

    Serum levels of venom antigen were measured using enzyme-linked immunosorbent assay (ELISA) in 38 Russel's viper bite victims before and after administration of 40 ml of monovalent liquid antivenom. Initial serum levels ranged from one with less than 10.0 ng to 290 ng/ml and in one case a level of 75 ng/ml was detected 27 hours after the bite. Serum venom levels after liquid monospecific antivenom therapy indicated that venom clearance was similar in each case to the natural clearance of venom in the absence of antivenom therapy. In one case a venom level of 11.5 ng/ml was detected 66 hours after liquid antivenom therapy whereas in two fatal cases, serum venom levels of 95 ng/ml and 185 ng/ml were detected after the same interval. Failure of complete neutralization of venom is probably the result of loss of potency of antivenom during improper storage. The amount of venom excreted in the urine was not related to initial serum levels. PMID:6464103

    Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

    The association of vitiligo and pernicious anemia has been previously documented. The low levels of folic acid and vitamin B12 were thought to be related to vitiligo. To date, there have been very few reports about the serum levels of folic acid and vitamin B12 in patients with vitiligo. Using radioimmunoassay, we measured the serum levels of folic acid and vitamin B12 in 100 Korean patients with vitiligo. The mean serum levels of folic acid and vitamin B12 were 6.31 +/- 2.82 ng/ml and 630.25 +/- 230.94 pg/ml, respectively, in patients with vitiligo. These levels showed no significant difference compared to the normal control group, suggesting that folic acid and vitamin B12 do not appear to play a role in the pathogenesis of vitiligo.

    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.

  5. Clinical significance of changes of serum gastrin levels in patients with chronic eczema or chronic urticaria

    International Nuclear Information System (INIS)

    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.

  6. 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.

    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.

    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.

    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

    Full Text Available Background: Increasing evidence suggests an association between ele­vated serum aminotransferase levels and metabolic disorders (metabolic syndrome, hyperlipemia and diabetes mellitus. However, the significance of relatively low levels of aminotransferases in relation to metabolic disorders has not been fully investigated in the general population. We inves­tigated the association between serum amiontransferase levels and metabolic disorders using data from a survey in Jilin province, China.Methods: In 2007, a survey was conducted throughout Jilin, China, covering both urban and rural areas. A total of 3835 people, 18 to 79 years old including 1761 men and 2074 women, underwent real-time ultrasonography, blood tests including aspartate aminotransferase and alanine aminotransferase, and had interviews with a structured questionnaire.Results: Serum aminotransferase levels within the normal range were asso­ciated with metabolic syndrome independent of age, occupation, cultural and educational level, income, body mass index, waist circumference, smoking, and alcohol intake. Compared with the lowest level (50 IU/L were 1.92, 2.50, 2.97, and 3.52 in men, and 1.38 , 1.54, 3.06, and 2.62 in women, respectively. Near-normal serum aminotransferase levels asso­ciated with hyperlipemia, NAFLD, DM were also found in the study.Conclusions: Normal to near-normal serum aminotransferase levels are associated with metabolic disorders. Serum ALT levels of 21-25 IU/L for men, and 17-22 IU/L for women are suggested as cutoff levels that detect metabolic disorders affecting the liver.

    The present study analysed the effect of protein restriction on serum insulin and leptin levels and their relationship with energy balance during lactation. Four groups of rats received isocaloric diets containing 170 g protein/kg or 60 g protein/kg from pregnancy until the 14th day of lactation: control non-lactating, control lactating (both fed a control diet), low-protein non-lactating and low-protein lactating. Energy intake, body composition, energy balance, serum insulin and leptin concentrations and the relationship between these hormones and several factors related to obesity were analysed. Low-protein-intake lactating rats exhibited hypoinsulinaemia, hyperleptinaemia, hypophagia and decreased energy expenditure compared with control lactating rats. The protein level in the carcasses was lower in the low-protein lactating group than in the control lactating group, resulting in a higher fat content in the first group compared with the latter. Body fat correlated inversely with serum insulin and positively with serum leptin level. There was a significant negative correlation between serum leptin and energy intake, and a positive relationship between energy intake and serum insulin level in lactating rats and in the combined data from both groups. Energy expenditure was correlated positively with serum insulin and negatively with serum leptin in lactating rats and when data from control non-lactating and lactating rats were pooled. Lactating rats submitted to protein restriction, compared with lactating control rats, showed that maternal reserves were preserved owing to less severe negative energy balance. This metabolic adaptation was obtained, at least in part, by hypoinsulinaemia that resulted in increased insulin sensitivity favouring enhanced fat deposition, hyperleptinaemia and hypophagia.

  1. 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

    Among the active components in traditional anti-diabetic herbal plants, berberine which is an isoquinoline alkaloid exhibits promising potential for its potent anti-inflammatory and hypoglycemic effects. However, the berberine effect on serum glucose levels in type 1 diabetes (T1D) subjects still remains unknown. This study investigated berberine's effects on serum glucose levels using non-obese diabetic (NOD) mice that spontaneously develop T1D. The NOD mice were randomly divided into four groups, administered water with 50, 150, and 500 mg berberine/kg bw, respectively, through 14 weeks. ICR mice were also selected as a species control group to compare with the NOD mice. Changes in body weight, oral glucose challenge, and serum glucose levels were determined to identify the protective effect of berberine on T1D. After the 14-week oral supplementation, berberine decreased fasting serum glucose levels in NOD mice close to the levels in normal ICR mice in a dose dependent manner. Serum berberine levels showed a significantly (Pberberine-administered NOD mice. Our results suggested that berberine supplemented at appropriate doses for 14 weeks did not cause toxic side effects, but improved hyperglycemia in NOD mice.

  3. 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

  4. Serum total bilirubin levels and coronary heart disease--Causal association or epiphenomenon?

    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

    Objectives: To investigated serum cortisol and serum dehydroepiandrosterone-sulphate (DHEA-S) levels between fibromyalgia (FMS) patients and a control group, and the effect of balneotherapy (BT) on these hormones. Methods: Seventy-two patients with FMS and 39 healthy volunteers were included in the study. This prospective and cross-sectional study was carried out in the Medical Faculty, Physical Medicine and Rehabilitation Clinic, Cumhuriyet University, Cumhuriyet, Turkey between June 2012 and June 2013. Patients were divided into 2 groups. There were 40 patients in the first group, consisting of BT and physical therapy (PT) administered patients. There were 32 FMS patients in the second group who were only administered PT. Thirty-nine healthy volunteers were enrolled as a control group. Result: Cortisol was observed to be lower in FMS patients compared with the controls (10.10±4.08 μg/dL and 11.78±3.6 μg/dL; p=0.033). Serum DHEA-S level was observed to be lower in FMS patients compared with the controls (89.93±53.96 μg/dL and 143.15±107.92 μg/dL; p=0.015). Average serum cortisol levels of patients receiving BT were determined to be 9.95±3.20 μg/dL before treatment and 9.06±3.77μg/dL after treatment; while average serum DHEA-S levels were 77.60±48.05 μg/dL before treatment, and 76.84±48.71 μg/dL after treatment. No significant changes were determined in serum cortisol and DHEA-S levels when measured again after BT and PT. Conclusion: Low levels of serum cortisol and DHEA-S were suggested to be associated with the physiopathology of FMS. PMID:27146618

    The effect of labor on maternal serum copper levels was determined in normal and complicated pregnancies. The mean value +/- SD (3.16 +/- 0.48 micrograms/ml) in 82 clinically normal subjects at term during labor was compared with that (2.22 +/- 0.49 micrograms/ml) obtained from 50 controls matched for gestational age who were not in labor. Similarly, the mean value in labor (3.56 +/- 0.46 micrograms/ml) in 25 subjects with a complicated pregnancy was compared with that (2.87 +/- 0.43 micrograms/ml) obtained from 25 similar subjects prior to labor. A statistically significant difference (P less than .001) was observed in both comparisons. Copper levels in the corresponding fetal serum from the subjects in labor (normal and complicated) were compared with those of the maternal serum samples. The mean value of fetal serum samples in mothers with complications was higher than that in normal mothers, but the difference was not statistically significant. This trend of a rise in serum copper level during labor was further confirmed by analysis of the same subject during and before labor in normal (12 subjects) and complicated pregnancies (9 subjects). Moreover, maternal serum estriol and estetrol levels were determined from the same samples in the 4 groups to find a possible relationship with the corresponding copper levels. No statistically significant correlation was noted. A possible explanation for the rise of the serum copper level with the onset of labor and its clinical implications are also discussed.

    2011-03-01

    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............

    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.

  10. 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

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

    Full Text Available 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.

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

    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. To improve assessment of dystrophinopathy, the aim of this study was to identify whether serum creatinine (Crn level reflects disease severity. Methods. Biochemical, Vignos score, and genetic data were collected on 212 boys with dystrophinopathy. Results. Serum Crn level had a strong inverse correlation with Vignos score by simple correlation (r=-0.793 and partial correlation analysis after adjustment for age, height, and weight (r=-0.791; both P<0.01. Serum Crn level was significantly higher in patients with in-frame than out-of-frame mutations (Z=-4.716, P<0.01 and in Becker muscular dystrophy (BMD patients than Duchenne muscular dystrophy (DMD patients at ages 4, 5, 7, and 9 yr (all P<0.0125. After adjusting for age, height, and weight, BMD patients still had a significantly higher serum Crn level than DMD patients (β=7.140, t=6.277, P<0.01. Conclusions. Serum Crn level reflected disease severity and may serve as a supplemental index to distinguish DMD from BMD in clinical practice.

    H1-receptor inhibiting drugs, namely loratadine and cetirizine, were frequently used in treatment of chronic urticaria. Urticarial weal and flare reactions, a neurogenic reflex due to neuropeptides, were reported to be more effectively inhibited by cetirizine than loratadine. The aim of this study was to determine and compare the effects of systemic loratadine and cetirizine treatments on serum levels of selected neuropeptides in chronic urticaria. Treatment groups of either systemic loratadine or cetirizine (10 mg/d), consisting of 16 and 22 patients, respectively, were included. Serum levels of stem cell factor (SCF), neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), nerve growth factor (NGF), vasoactive intestinal peptide (VIP), and substance P (SP) were detected before and after one week of treatment with antihistamines. Serum NPY and VIP levels were significantly decreased when compared before and after treatment with antihistamines (P neuropeptides. Systemic loratadine and cetirizine treatments in patients with chronic urticaria precisely caused variations in serum levels of neuropeptides. The predominant effect of cetirizine compared to loratadine on reducing serum SCF levels might be explained with anti-inflammatory properties of cetirizine.

    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.

    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.

    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

    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 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.

    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.

    We measured serum PIVKA-II concentrations in 18 patients with alcoholic liver cirrhosis. Alcoholic liver disease was diagnosed by the history of ethanol intake of more than 900 ml/day for over 10 years. Liver cirrhosis was diagnosed histologically. Infections with hepatitis B and C viruses were ruled out by assaying serum virus markers. No tumor was detected in liver by ultrasonography and computed tomography during observation period. None of the patients studied were positive for alpafetoprotein (AFP). Eight out of 18 (44.4%) patients with alcoholic liver cirrhosis showed elevated serum PIVKA-II levels. In contrast, only eight out of 93 (8.6%) patients with nonalcholic liver cirrhosis had elevated serum PIVKA-II levels. PIVKA-II is well known as a tumor marker of hepatocellular carcinoma (HCC). The rates of positive PIVKA-II found in alcoholic liver cirrhosis approached its rates in HCC. However, the time course for the elevation of serum PIVKA-II levels was different each other in alcoholic liver cirrhosis and HCC. In HCC, serum PIVKA-II "levels" continued to elevate until therapy. In contrast, its elevation was transient and its levels returned to baseline in alcoholic liver cirrhosis. The values of ALT (GPT), gamma-GTP, and ALP correlated poorly with serum PIVKA-II levels in patients with alcoholic liver cirrhosis. To investigate the mechanism by which elevation of serum PIVKA-II levels in patients with alcoholic liver cirrhosis occurred, we studied the effect of vitamin K on production of PIVKA-II and AFP by hepatocytes. Hepatocytes(Alexander PLC/PRF/F cell line) were cultured in the presence of various concentrations of vitamin K (Kaytwo, Eisai, Tokyo). Vitamin K had no effect on AFP production. In contrast, PIVKA-II production was inhibited by addition of vitamin K in a dose dependent manner. Moreover, elevation of serum PIVKA-II levels in patients with alcoholic liver cirrhosis was suppressed by administration of vitamin K (Kaytwo) to these patients. Taken

    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.

    Substance P (SP), a member of tachykinin family, is involved in the inflammation of the central nervous system and in the appearance of cerebral edema. Higher serum levels of SP have been found in 18 patients with cerebral ischemia compared with healthy controls. The aim of our multi-center study was to analyze the possible association between serum levels of SP and mortality in ischemic stroke patients. We included patients with malignant middle cerebral artery infarction (MMCAI) and a Glasgow Coma Scale (GCS) lower than 9. Non-surviving patients at 30 days (n = 31) had higher serum concentrations of SP levels at diagnosis of severe MMCAI than survivors (n = 30) (p < 0.001). We found in multiple regression an association between serum concentrations of SP higher than 362 pg/mL and mortality at 30 days (Odds Ratio = 5.33; 95% confidence interval = 1.541–18.470; p = 0.008) after controlling for age and GCS. Thus, the major novel finding of our study was the association between serum levels of SP and mortality in patients suffering from severe acute ischemic stroke. PMID:27338372

    AIM:The healthy ranges for serum alanine aminotransferase (ALT) levels are less well studied. The aim of this study was to define the upper limit of normal (ULN) for serum ALT levels, and to assess factors associated with serum ALT activity in apparently healthy blood donors.METHODS: A total of 1 939 blood donors were included.ALT measurements were performed for all cases using the same laboratory method. Healthy ranges for ALT levels were computed from the population at the lowest risk for liver disease. Univariate and multivariate analyses were performed to evaluate associations between clinical factors and ALT levels.RESULTS: Serum ALT activity was independently associated with body mass index (BMI) and male gender, but not associated with age. Association of ALT with BMI was more prominent in males than in females. Upper limit of normal for non-overweight women (BMI of less than 25) was 34 U/L,and for non-overweight men was 40 U/L.CONCLUSION: Serum ALT is strongly associated with sex and BMI. The normal range of ALT should be defined for male and female separately.

    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

  16. 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)

    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.

    The orexigenic peptide, ghrelin, is regulated by acute and chronic nutritional state. Although exogenously administered ghrelin stimulates pituitary GH secretion, little is known about the role of ghrelin in endogenous GH secretion or how high GH and IGF-I levels in acromegaly could affect ghrelin secretion and vice versa. Therefore, we evaluated fasting and post oral glucose tolerance test serum ghrelin levels in 19 patients with active acromegaly at baseline and after either surgery in 9 of these or administration of long-acting octreotide (Sandostatin LAR) in the other 10 patients. After surgical cure, fasting ghrelin rose from 312 +/- 56 pg/ml to 548 +/- 97 pg/ml (P = 0.013). Fasting serum ghrelin levels were higher in all patients after surgery and ranged between 112% and 349% of presurgery levels. Ghrelin levels fell significantly during long-acting octreotide therapy from 447 +/- 34 pg/ml to 206 +/- 15 pg/ml (P acromegaly; lowered serum levels of ghrelin in active acromegaly rise along with the postsurgery normalization of GH and IGF-I and improved insulin resistance. In contrast to surgical therapy, long-acting octreotide therapy persistently suppressed serum ghrelin levels. It remains to be determined whether altered circulating ghrelin concentrations could impact on body composition changes in acromegaly.

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

    Full Text Available Background. Osteopontin (OPN has been proved to be associated with allergic airway inflammation. However, the roles of OPN and its regulation in childhood allergic rhinitis (AR are poorly understood. Objective. This study aims to evaluate the expression of OPN and miR-181a in children with AR and their association with Th1/Th2 immune response. Methods. Children who suffered from AR were included along with control subjects. Serum was collected to examine the level of OPN and Th1/Th2 cytokines by enzyme-linked immunosorbent assay (ELISA and the level of miR-181a by quantitative polymerase chain reaction (qPCR. Results. Children with AR had significantly higher serum levels of OPN and lower serum levels of miR-181a than healthy controls. Furthermore, serum levels of OPN were positively correlated with Th2 cytokine and negatively correlated with Th1 cytokine. On the contrary, miR-181a level had a negative correlation with IL-4/IL-5 and positive correlation with IFN-γ/IL-12. More importantly, there was also significant negative correlation between OPN and miR-181a. Conclusion. The OPN protein and miR-181a levels may serve as predictors of disease severity in childhood AR and appear to be promising targets for modulating AR.

    Full Text Available Background: Giardia lamblia is one of the most important intestinal parasites. The aim of this study was to measure serum levels of IgA, IgE, zinc, copper, vitamin B12 and folate in individuals with giardiasis in comparison to normal subjects.Methods: The study was carried out among 49 Giardia positive and 39 age and sex matched healthy volunteers. Examination of stool samples was done by direct wet smear and formol-ether concentration method. Serum samples were obtained for further laboratory examination. IgA levels were measured by Single Radial Immune Diffusion (SRID. IgE levels were measured by ELISA kit. Zinc and copper levels was measured by Ziestchem Diagnostics Kit and colorimetric endpoint-method respectively. Vitamin B12 and folate levels were measured by DRG Diagnostics Kit and Enzyme Immunoassay method respectively. All data were analyzed using SPSS version 17.Results: There was a statistically significant difference in IgA, IgE, copper and zinc levels between positive and negative groups (P<0.05. There was no significant difference between vitamin B12 and folate levels between the two groups. Mean values of Giardia positive and negative groups for IgA were 309.26 and 216.89 mg/dl, IgE 167.34 and 35.49 IU/ml, copper 309.74 and 253.61 µg/dl and zinc 69.41 and 144.75 µg/dl respectively.Conclusion: The results showed levels of IgA may correlate more closely with giardiasis than IgE. Regarding trace elements, giardiasis elevated serum copper levels, while it decreased serum zinc. Finally, there was no significant difference in serum levels of vitamin B12 and folic acid between the two groups.

    Full Text Available Emphysema and idiopathic pulmonary fibrosis (IPF present either per se or coexist in combined pulmonary fibrosis and emphysema (CPFE. Serum surfactant proteins (SPs A, B, C and D levels may reflect lung damage. We evaluated serum SP levels in healthy controls, emphysema, IPF, and CPFE patients and their associations to disease severity and survival.122 consecutive patients (31 emphysema, 62 IPF, and 29 CPFE and 25 healthy controls underwent PFTs, ABG-measurements, 6MWT and chest HRCT. Serum levels of SPs were measured. Patients were followed-up for 1-year.SP-A and SP-D levels differed between groups (p = 0.006 and p<0.001 respectively. In post-hoc analysis, SP-A levels differed only between controls and CPFE (p<0.05 and CPFE and emphysema (p<0.05. SP-D differed between controls and IPF or CPFE (p<0.001 for both comparisons. In IPF SP-B correlated to pulmonary function while SP-A, correlated to the Composite Physiological Index (CPI. Controls current smokers had higher SP-A and SP-D levels compared to non-smokers (p = 0.026 and p = 0.023 respectively. SP-D levels were higher in CPFE patients with extended emphysema (p = 0.042. In patients with IPF, SP-B levels at the upper quartile of its range (≥26 ng/mL presented a weak association with reduced survival (p = 0.05.In conclusion, serum SP-A and SP-D levels were higher where fibrosis exists or coexists and related to disease severity, suggesting that serum SPs relate to alveolar damage in fibrotic lungs and may reflect either local overproduction or overleakage. The weak association between high levels of SP-B and survival needs further validation in clinical trials.

    We assessed the secular trends in the serum lipid levels in Shanghai residents from 1973 to 1999. Data from four independent, cross-sectional, population-based surveys were used to analyze the trends in serum lipid levels from 1973 to 1999. A standard protocol was applied across each survey in at least three independent surveys which were separated a 10-year study period. A total of 10733 (1385, 3302, 2399, and 3647 subjects who had complete data on serum lipids in 1973-1974, 1982, 1983 and 1997-1999, respectively) Shanghai residents aged from newborn to 80 years old were enlisted at random. Serum lipid levels were measured in a single laboratory throughout the entire study period. A non-significant increase was noted from 1973-1974 to 1982-1983 in the serum lipid profiles; however, a significant increase was observed from 1982-1983 to 1997-1999 in most of the age groups of both sexes. Mean serum total cholesterol (TC) levels increased significantly (P 40 it was from 5.5% to 11.57%. In females, it was 0 to 4.68% and 6.5% to 16.2%, respectively. In general, the trends in the levels of TC, TG and LDL-c were increasing and trends in the levels of HDL-c were decreasing in most age groups, especially, in the younger age group of Shanghai residents from 1980s to 1990s. These worrying findings are significant for its public health implications. Health education and health pro-motion are necessary to prevent the disease prevalence from rising in the Chinese population.

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

  14. Effect of therapeutic irradiation on serum amylase levels of cancer patients

    International Nuclear Information System (INIS)

    Serum amylase levels were estimated in forty cancer patients treated by radiotherapy. Amylase levels of normal controls and cancer patients did not reveal any significant differences. Amylase levels in cases with oral cancer were in the lower range as compared to the levels in cancer cases of other sites. Significant rise of levels in oral cancer cases after first sitting of 200 rads was attributed to hyperamylasia, produced in salivary glands by irradiation. Other amylase contributing organs showed the changes in the levels by irradiation but to a lesser extent. Pre- and post-radiotherapy amylase levels in most of the cancer cases were not significantly different. (author). 3 tables, 5 refs

    Full Text Available Objectives. This study investigated whether Sasang constitutional type is associated with differences in the serum levels of stress hormones and oxidative stress. Methods. A total of 236 participants (77 males and 159 females were enrolled. The serum levels of cortisol, adrenaline, reactive oxygen species (ROS, and malondialdehyde (MDA were analyzed. Results. The distribution of Sasang constitutional types was as follows: Taeumin, 35.6%; Soumin, 33.0%; and Soyangin, 31.4%. The serum cortisol levels of Taeumin were significantly lower than Soumin (p<0.1 in both sexes and Soyangin (p<0.05 in males and p<0.1 in females. The adrenaline levels were also significantly lower in Taeumin than in Soumin (p<0.05 in males and p<0.1 in females and Soyangin (p<0.1 in males. Serum ROS levels were significantly higher in Soyangin than in Taeumin and Soumin (p<0.05 in males, whereas MDA levels were significantly lower in Taeumin compared with Soumin and Soyangin (p<0.05 in males and p<0.1 in females. Conclusion. Taeumin type may tolerate psychological or oxidative stress better than other types, which suggests a biological mechanism to explain the different pathophysiological features of Sasang constitutional types.

    Full Text Available Abstract Background Lipid metabolism is altered in subjects with liver steatosis. FAS is a key enzyme in de novo lipogenesis and both FAS gene expression and enzymatic activity are primarily regulated by metabolic signals in the liver. Lipoprotein lipase (LPL, the rate-limiting enzyme for the hydrolysis of core triglycerides, plays a pivotal role in lipid metabolism. This study aims to investigate if circulating levels of FAS and LPL could be clinically associated with liver steatosis. Methods In this work, we present data obtained from a subsample of 94 subjects with liver steatosis enrolled by NUTRIEPA study, a nutritional trial in subjects with liver steatosis. Serum levels of FAS protein and LPL activity were evaluated by ELISA test and by a fluorescent method, respectively. The diagnosis and the degree of liver steatosis were based on laboratory and ecographic measurements. Statistical methods included Kruskal-Wallis analysis of variance and Wilcoxon signed-rank test, where appropriate. The χ2 test has been performed to analyse categorical variables. Results The subjects with severe steatosis had significantly higher serum levels of FAS protein and LPL activity compared to subjects with mild and moderate liver steatosis. Moreover, a positive trend in serum levels of FAS expression from lower to higher degree of steatosis was also detected. Conclusions We describe a relationship between human liver steatosis and elevated levels of circulating lipogenic enzymes. Increased serum levels of FAS expression and LPL activity could be considered a marker of severe liver steatosis.

These findings were supported by experimental results in rabbits, in which low, medium, and high doses of purified V. palaestinae venom (all in the non-lethal range), led to dose-dependent decreases in serum cholesterol, at 180 minutes, of 9.5% +/- 8.9%, 18.6% +/- 10.1%, and 32.7% +/- 11.8%, respectively (p serum cholesterol level is only partially explained by transcapillary lipoprotein leakage and probably indicates changes in lipoprotein transport and metabolism caused by the phospholipase A2 component of V. palaestinae venom. Admission total serum cholesterol level may serve as an indicator of severity of envenomation in patients bitten by snakes of the Vipera genus before full development of the clinical syndrome.

    It has been proposed that the neurotrophin brain-derived neurotrophic factor (BDNF) may be involved in attention deficit-hyperactivity disorder (ADHD) etiopathogenesis. Alterations in BDNF serum levels have been observed in childhood/adulthood neurodevelopmental pathologies, but no evidence is available for BDNF serum concentrations in ADHD. The study includes 45 drug-naïve ADHD children and 45 age-sex matched healthy subjects. Concentration of serum BDNF was determined by the ELISA method. BDNF serum levels in patients with ADHD were not different from those of controls (mean ± SD; ADHD: 39.33 ± 10.41 ng/ml; controls: 38.82 ± 8.29 ng/ml, t = -0.26, p = 0.80). Our findings indicate no alteration of serum BDNF levels in untreated patients with ADHD. A further stratification for cognitive, neuropsychological and psychopathological assessment in a larger sample could be useful to clarify the role of BDNF in the endophenotype characterization of ADHD.

    Objective. To investigate the dynamic changes of serum vascular endothelial growth factor(VEGF) levels in a rat model of acute myocardial infarction. Materials and methods. Eighty-eight adult male Sprague-Dawley rats weighing approximately 270 g were used in this study. Eighty rats were subjected to left coronary artery ligation, with 8 rats for each different duration of infarct.Eight sham-operated animals in which the left coronary artery was surgically exposed without ligation were used as con-trols. Blood samples were drawn from the right atrium before ( sham animals ) and 1,3,6,12,24 h and 2,3,5,7,14 dafter myocardial infarction. The concentrations of serum VEGF were measured by a sensitive enzyme-linked im munosorbent assay with a rabbit polyclonal antibody specific for VEGF. Results. In the 8 control animals, the mean concentration of serum VEGF was 66.99 ± 17.83 pg/ml. Six hours after myocardial infarction, the level of serum VEGF significantly increased to 125.68 ± 28.07 pg/ml ( P <0.01 vs. sham controls), and reached a peak (240.61 ± 70.63 pg/ml. P <0.01 vs. sham animals) at 24 h after ligation and then decreased gradually over the remaining 2 weeks. However, the level remained significantly elevated for 14 d(107.64±30.13pg/ml, P<0.01 vs. sham controls). Condusion. The present study shows that the levels of serum VEGF are markedly increased until 14 d in the ratmodel of acute myocantial infarction. The increased serum VEGF level may play an important role in the angiogencsisassociated with myocardial infarction.

    Full Text Available Background: Both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. Little is known about the relations of serum uric acid (UA level to regional arterial stiffness and wave reflection. The aim of the study was to investigate the gender-specific association of serum UA and indices of arterial function in a community-based investigation in China.Methods: Cross-sectional data from 2374 adults (mean age 58.24 years who underwent routine laboratory tests, regional pulse wave velocity (PWV and pulse wave analysis measurements were analyzed in a gender-specific manner. None of the participants had atherosclerotic cardiovascular disease, chronic renal failure, systemic inflammatory disease, gout, or were under treatment which would affect serum UA level.Results: Men had higher serum UA level than women. Subjects with hyperuricaemia had significantly higher carotid-ankle PWV in both genders (P< 0.05, and the carotid-femoral PWV (PWVc-f was higher in women (P< 0.001 while the augmentation index was marginally lower in men (P = 0.049. Multiple regression analysis showed that serum UA was an independent determinant only for PWVc-f in women (β = 0.104, P = 0.027 when adjusted for atherogenic confounders. No other independent relationship was found between UA level and other surrogates of arterial stiffness.Conclusions: Serum UA levels are associated with alterations in systemic arterial stiffness that differ in men and women. Women might be more susceptible to large vascular damage associated with hyperuricaemia.

    Objective: The aim of this experimental study was to assess the effect of erythropoietin on a rat model, particularly under a renal ischemia reperfusion protocol. The beneficial or lack of effects of that molecule on the excreted renal product of serum uric acid were studied biochemically. Material and methods: Forty rats were used with a mean weight of 247.7 gr. Serum uric acid levels were measured measured at 60 min after reperfusion (Groups A and C) and at 120 min after reperfusion (groups B and D). Results: 1) Erythropoietin administration non-significantly decreased the serum uric acid levels non-significantly by 0.02 mg/dL [−0.2415423 mg/dL-0.2015423 mg/dL] (p=0.8560), in accordance with the paired t-test (p=0.8438). Reperfusion time non-significantly increased the serum uric acid levels non-significantly by 0.17 mg/dL [−0.0444933 mg/dL-0.3844933 mg/dL] (p=0.1169), in accordance with the paired t-test (p=0.1648). 3) The interaction of erythropoietin administration and reperfusion time non-significantly increased the serum uric acid levels non-significantly by 0.1 mg/dL [−0.0295564 mg/dL-0.2295564 mg/dL] (p=0.1264). Conclusion: Erythropoietin administration, reperfusion time and their interaction have no significant short-term alterations on serum uric acid levels. Conclusions cannot be extracted by non-significant p-values within 2 hours. Obviously, longer study times may permit safer results. PMID:26328161

    Full Text Available Whether serum magnesium deficiency is independently associated with the prevalence of microalbuminuria is still unclear. The objective of the present study was to elucidate the association between serum magnesium and microalbuminuria in diabetic patients. A cross-sectional study was conducted in 1829 diabetic subjects (aged ≥ 40 years from Shanghai, China. Subjects were divided into three groups according to serum magnesium tertiles. A first-voided early-morning spot urine sample was obtained for urinary albumin-creatinine ratio (UACR measurement. Microalbuminuria was defined as 30 mg/g ≤ UACR < 300 mg/g. Overall, 208 (11.37% of the study population had microalbuminuria, with similar proportions in both genders (. The prevalence of microalbuminuria in tertile 1 of serum magnesium was higher than the prevalence in tertile 2 and tertile 3 (15.98%, 9.72%, and 8.46%, resp.; for trend <0.0001. After adjustment for age, sex, BMI, blood pressure, lipidaemic profile, HbA1c, eGFR, history of cardiovascular disease, HOMA-IR, antihypertensive and antidiabetic medication, and diabetes duration, we found that, compared with the subjects in tertile 3 of serum magnesium, those in tertile 1 had 1.85 times more likeliness to have microalbuminuria. We concluded that low serum magnesium level was significantly associated with the prevalence of microalbuminuria in middle-aged and elderly Chinese.

  4. Effect of stress on serum cholestrol levels in nurses and housewives of Hyderabad - Pakistan

    International Nuclear Information System (INIS)

    A cohort type study was designed to evaluate environmental, psychological and physiological stresses in nurses and housewives and to correlate with their serum total cholesterol, HDL cholesterol, LDL cholesterol and triglyceride levels. Total 160 females from middle socioeconomic groups (nurses, n=80 and housewives, n=80) aged between 25-45 years participated in this study and subjects were selected from Hyderabad and its adjoining areas. Environmental, psychological and physiological stress levels were measured with likert scale. Total cholesterol, LDL cholesterol and HDL cholesterol were measured by CHOD-PAP method and triglyceride levels were measured by GPO method. Housewives were found to have high levels of total cholesterol, LDL cholesterol and triglycerides. The HDL cholesterol were lower. Environmental, psychological and physiological stresses were significantly higher in housewives as compared to the nurses. Highest level of environmental stress was observed in nonworking group i.e. housewives. A significant relation between serum cholesterol levels and three types of stresses was observed. (author)

    Full Text Available Objective: To investigate the serum 25-hydroxy vitamin D levels in systemic treatment planned premenopausal psoriasis patients and compare it with the same age and sex matched healthy volunteers. Materials and Methods: Forty-one psoriasis patients and 57 healthy controls (total of 98 were included in the study. Serum 25-hydroxy vitamin D levels were compared between the two groups; also the relationship of disease activity and 25-hydroxy Vitamin D levels were examined in patients with psoriasis. Probability values of 0.05. In addition, the mean 25-hydroxy vitamin D levels were not significantly different among the two groups (p>0.05. 25-hydroxy vitamin D levels were no significantly different in patients with and without psoriatic arthritis (p>0.05. No significant correlation was found between psoriasis area severity index PASI values, age or 25-hydroxy vitamin D levels (p>0.05. Conclusion: The low levels of vitamin D in population is reported to be common. In our study, similar low vitamin D levels were found in healthy volunteers and premenopausal psoriasis patients. Serum 25-hydroxy vitamin D levels were not correlated with disease activity in patients with psoriasis. Correlation between psoriasis, disease activity and vitamin D levels should be investigated in larger populations. (Turkish Journal of Osteoporosis 2014;20: 93-7

    Full Text Available Abstract Background Serum anti-Müllerian hormone (AMH had been proposed as a marker of ovarian reserve. The aim of this study was to evaluate the impact of endometrioma and laparoscopic cystectomy on ovarian reserve as measured by serum AMH levels. Methods A total of 1,642 patients were recruited in this retrospective analysis. Control group (group 1 included 1,323 infertility patients without endometrioma. Endometrioma group (group 2 included 141 patients with ovarian endometrioma. Previous cystectomy group (group 3 included 147 patients who underwent unilateral or bilateral laparoscopic cystectomy due to ovarian endometrioma more than 6 months before enrollment. Current cystectomy group (group 4 included 31 patients who underwent cystectomy during study period. Serum anti-müllerian hormone (AMH levels were measured upon enrollment with all patients. For patients in group 4, AMH levels were measured before and 3 months after cystectomy. Results Mean AMH level of patients in control group was significantly higher than that of endometrioma group or previous cystectomy group in each age subgroup, while the mean serum AMH level of the endometrioma group was also significantly higher than that of the previous cystectomy group in each age subgroup. The mean AMH level was significantly lower in patients with previous bilateral cystectomy compared to that of patients with unilateral cystectomy. The mean serum AMH level was also significantly lower in patients with bilateral endometrioma compared to that of patients with unilateral endometrioma. In group 4, mean AMH level significantly decreased from 3.95 +/- 0.42 preoperation to 2.01 +/- 0.21 ng/ml at 3-month postoperation. Conclusions Both ovarian endometrioma and cystectomy are associated with a significant reduction on ovarian reserve. Bilateral endometrioma exerts a more profound negative impact on ovarian reserve than unilateral endometrioma, regardless of either conservative or surgical

    The purpose of this study was to investigate the relationship between serum taurine level and serum adiponectin or leptin levels in high-fat diet-induced obesity rats. Five-week-old male Sprague-Dawley rats were randomly divided into three groups for a period of 8 weeks (normal diet, N group; high-fat diet, HF group; high-fat diet + taurine, HFT group). Taurine was supplemented by dissolving in feed water (3% w/v), and the same amount of distilled water was orally administrated to N and HF groups. In serum, adiponectin level was higher in HFT group compared to HF group. The serum taurine level was negatively correlated with serum total cholesterol (TC) level and positively correlated with serum adiponectin level. These results suggest that dietary taurine supplementation has beneficial effects on total cholesterol and adiponectin levels in high-fat diet-induced obesity rats.

    Full Text Available To study the effects of Babesia infection on urea and creatinine serum samples were randomly collected from 253 Nigerian local (Arewa breed of Royal stallions and their Arabian and Sudanese crosses from five towns in Niger state, Nigeria. These horses were categorized into 5 groups based on their infection status. Urea and creatinine was assayed using spectrophotometer. Collected fecal samples were analy- zed using simple floatation method. The result showed non significant difference in serum levels of urea and creatinine in the various categories of horses namely Babesia infected horses, mixed Babesia + gastro-intestinal parasites infected horses, gastrointestinal parasites infected horses, negative apparently healthy and negative apparently sick horses. It can be concluded that natural Babesia infection in Nigerian local horses does not alter serum urea and creatinine levels.

    Full Text Available In unstable angina (USA patients, immunological responses contributing to inflammation play a vital role in plaque rupture and thrombosis causing stroke. In the present study an attempt is made to estimate the levels of adenosine deaminase activity, an immunoenzyme marker and C-reactive protein, a marker of inflammation in USA patients. 45 patients presenting USA and 50 age and sex matched healthy controls were included in the study. Serum ADA activity was measured spectrophotometrically at 630nm and serum C-reactive protein was detected using Avitex CRP kit, which is a rapid latex agglutination test. The Mean ADA levels were 41.15 ± 11.04 in patients and 20.71±5.63 in controls and 66.6% of patients and none of the controls were positive to CRP. The present study observed the importance of ADA as a serum marker in addition to CRP for assessing the immune response in USA patients.

    A 65-year-old man was admitted to our hospital in January 1992 for chemotherapy and radiation therapy against primary lung cancer, which was diagnosed as a squamous cell carcinoma by a transbronchial lung biopsy. The lung tumor was decreased in size and he was discharged in May 1993. Twenty-five days after discharge, he experienced fever and dyspnea, and was readmitted to our hospital. His chest x-ray and laboratory data suggested that he had radiation pneumonitis and his serum KL-6 level was high. Despite the treatment with methylprednisolone, prednisolone and cyclophosphamide, his serum KL-6 levels rapidly increased and correlated with his serum LDH levels and reversely correlated with the levels of PaO{sub 2} and opacities on chest x-ray films. An autopsy revealed a diffuse alveolar damage with proliferated type II pneumocytes, which was consistent with radiation pneumonitis, but was not associated with any infectious lesions. The findings in this case suggest that the serum KL-6 could be consistently high and that KL-6 levels could be a useful monitoring marker for radiation pneumonitis. (author)

    Full Text Available Background The existing therapeutic methods for neonatal jaundice are costly, time-consuming and potentially risky. Zinc salts can reduce phototherapy duration by precipitating unconjugated bilirubin in the intestine (bilirubin and zinc can form a complex in physiologic pH; however, zinc toxicity is an issue that must be considered since theoretically bilirubin reduction by phototherapy may increase serum zinc levels, making additional zinc supplementation the potential cause of zinc toxicity. Objectives So, our purpose was evaluating the serum zinc level alterations before and after phototherapy, in hyperbilirubinemic newborns. Materials and Methods A prospective cohort study was performed at the children’s medical center of Tehran University of Medical Sciences from 2012 to 2014. Healthy, full-term exclusively breast fed newborns with non-hemolytic jaundice were enrolled in the study. Participants were divided into two groups based on serum bilirubin levels (TSB 200 in only neonates with severe hyperbilirubinemia. Conclusions Phototherapy increases serum zinc level by reducing bilirubin level so that additional supplementation of this element can lead potentially to zinc toxicity.

    Full Text Available BACKGROUND: Since soluble TRAIL exhibits anti-inflammatory and anti-atherosclerotic activities both in vitro and in animal models, this study was designed to assess the relationship between the serum levels of TRAIL and clinical outcomes in patients with acute myocardial infarction (AMI. METHODOLOGY/PRINCIPAL FINDINGS: Levels of TRAIL were measured by ELISA in serial serum samples obtained from 60 patients admitted for AMI, both during hospitalization and in a follow-up of 12 months, as well as in 60 healthy control subjects. Serum levels of TRAIL were significantly decreased in patients with AMI at baseline (within 24 hours from admission, compared with healthy controls, and showed a significant inverse correlation with a series of negative prognostic markers, such as CK, CK-MB and BNP. TRAIL serum levels progressively increased at discharge, but normalized only at 6-12 months after AMI. Of note, low TRAIL levels at the patient discharge were associated with increased incidence of cardiac death and heart failure in the 12-month follow-up, even after adjustment for demographic and clinical risk parameters (hazard ratio [HR] of 0.93 [95% CI, 0.89 to 0.97]; p = 0.001. CONCLUSIONS/SIGNIFICANCE: Although the number of patients studied was limited, our findings indicate for the first time that circulating TRAIL might represent an important predictor of cardiovascular events, independent of conventional risk markers.

    Full Text Available Prostate-specific antigen (PSA is well known as a specific tumor marker for prostate cancer, but carcinoembryonic antigen (CEA- and carbohydrate antigen 19-9 (CA19-9-elevating adenocarcinomas originating in the prostate gland are rare. We report a case of metastatic adenocarcinoma of the prostate gland with a high serum level of CEA and CA19-9 in a 78-year-old man in whom prostate cancer (T3N1M1 had been diagnosed 2 years ago and who was treated with androgen deprivation therapy. He visited the emergency department because of a loss of appetite and abdominal pain. The serum CEA and CA19-9 levels were increased to 218.9 ng/mL (normal, <5 ng/mL and 212 ng/mL (normal, <27 ng/mL, respectively. The serum PSA level was slightly elevated (4.41 ng/mL. Computed tomography demonstrated multiple liver metastases, para-aortic lymph node enlargement, and lung metastases. A liver biopsy was performed and the specimen showed high-grade adenocarcinoma with focal positive staining for PSA. Despite chemotherapy with docetaxel, the patient died 3 months after treatment. Based on this case and a review of the literature, an aggressive variant of prostatic carcinoma with a high serum level of CEA and CA19-9 and a low PSA level was shown to progress rapidly with a poor prognosis.

    Objective: To explore the expression and sign if icance of human epidermal growth factor (EGF) and nerve growth factor (NGF) in patients with knee osteoarthritis. Methods: RT-PCR and enzyme-linked immunosorbent assay were used to measure the serum EGF and NGF expression levels of patients with limb fracture and brain trauma injurry after 1 d, 3 d, 7 d, 14 d and the relationship between them was analyzed. The level was compared among the simple fracture group, traumatic brain injury group and the normal control group, with 40 cases in each group. Results: The serum NGF levels were significantly different among three groups. Serum NGF, EGF mRNA and protein levels gradually decreased with the increasing injury time in the limb fracture combined with brain injury group, traumatic brain injury group, the simple fracture group and the health control group (P<0.05). Conclusions: The serum of NGF, EGF levels significantly increased when limb fracture combined with brain injury, so EGF and NGF may be involved in the process of fracture healing.

    Full Text Available Systemic sclerosis (SSc is an often fatal disease characterized by autoimmunity and inflammation, leading to widespread vasculopathy and fibrosis. Lysophosphatidic acid (LPA, a bioactive phospholipid in serum, is generated from lysophospholipids secreted from activated platelets in part by the action of lysophospholipase D (lysoPLD. Sphingosine 1-phosphate (S1P, a member of the bioactive lysophospholipid family, is also released from activated platelets. Because activated platelets are a hallmark of SSc, we wanted to determine whether subjects with SSc have altered serum lysophospholipid levels or lysoPLD activity. Lysophospholipid levels were measured using mass spectrometric analysis. LysoPLD activity was determined by quantifying choline released from exogenous lysophosphatidylcholine (LPC. The major results were that serum levels of arachidonoyl (20:4-LPA and S1P were significantly higher in SSc subjects versus controls. Furthermore, serum LPA:LPC ratios of two different polyunsaturated phospholipid molecular species, and also the ratio of all species combined, were significantly higher in SSc subjects versus controls. No significant differences were found between other lysophospholipid levels or lysoPLD activities. Elevated 20:4 LPA, S1P levels and polyunsaturated LPA:LPC ratios may be markers for and/or play a significant role in the etiology of SSc and may be future pharmacological targets for SSc treatment.

    AIM: To examine the calcium metabolism of colorectal cancer(CRC) in patients with colorectal cancer and control patients.METHODS: Seventy newly diagnosed CRC patients were included. The healthy control group was age and gender matched (n=32). Particular attention was devoted to the relationship between serum calcium of patients, and levels of AFP, CEA, carbohydrate antigen 19-9 (CA 19-9) (that could be considered as prognostic factors). Furthermore, the Ca-sensing receptor (CaSR) gene A986S polymorphism was investigated in these patients, as well as the relationship between different CaSR genotypes and the data stated above.RESULTS: A lower level of ionized calcium (also corrected for albumin) was found in the serum of CRC patients with normal 25(OH) vitamin D levels. The ionized calcium concentration was inversely correlated with the serum level of CA 19-9. There was no difference in the distribution of CaSR genotypes, between CRC patients and general population. The genotypes did not correlate with other data examined.CONCLUSION: Based on these results, lower levels of serum calcium might be a pathogenic and prognostic factor in colorectal cancer.

    High serum day 3 FSH levels are associated with poor ovarian reserve and reduced fertility, but the interpretation of FSH values according to age is still not univocal. The purpose of this study was to determine age-dependent reference values in women with regular menstrual cycles and FSH as a guide for specialists. The study was performed at the Department of Mother-Infant of a University-based tertiary care centre. One-hundred ninety-two healthy normal menstruating women were recruited for the study. All patients attended the department on menstrual cycle day 3 for a blood sample for FSH and estradiol determination. A linear relationship between FSH or estradiol serum levels and age was observed. The FSH level increased by 0.11 IU for every year of age (1 IU for every 9 years of age). The values of FSH and estradiol corresponding to the 5th, 25th, 50th, 75th, 95th centiles for any specific age have been calculated. Serum FSH levels need to be interpreted according to age-dependent reference values. Serum FSH levels on 95th centile for any age may represent a warning sign for reduced ovarian reserve.

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