    level of S-protein-bound form of the terminal complex (SC5b-9). However, liposome-induced rise of SC5b-9 was significantly suppressed when serum HDL cholesterol levels increased by 30%. Increase of serum LDL to levels similar to that observed in heterozygous familial hypercholesterolemia also suppressed......Intravenously infused liposomes may induce cardiopulmonary distress in some human subjects, which is a manifestation of "complement activation-related pseudoallergy." We have now examined liposome-mediated complement activation in human sera with elevated lipoprotein (LDL and HDL) levels, since...... abnormal or racial differences in serum lipid profiles seem to modulate the extent of complement activation and associated adverse responses. In accordance with our earlier observations, cholesterol-rich (45 mol% cholesterol) liposomes activated human complement, as reflected by a significant rise in serum...

    The C-terminal domain (D4) of perfringolysin O binds selectively to cholesterol in cholesterol-rich microdomains. To address the issue of whether cholesterol-rich microdomains exist in the inner leaflet of the plasma membrane, we expressed D4 as a fusion protein with EGFP in MEF cells. More than half of the EGFP-D4 expressed in stable cell clones was bound to membranes in raft fractions. Depletion of membrane cholesterol with β-cyclodextrin reduced the amount of EGFP-D4 localized in raft fractions, confirming EGFP-D4 binding to cholesterol-rich microdomains. Subfractionation of the raft fractions showed most of the EGFP-D4 bound to the plasma membrane rather than to intracellular membranes. Taken together, these results strongly suggest the existence of cholesterol-rich microdomains in the inner leaflet of the plasma membrane

    In this study, the effect of desipramine (DMI) on phospholipid bilayers and parvoviral entry was elucidated. In atomistic molecular dynamics simulations, DMI was found to introduce disorder in cholesterol-rich phospholipid bilayers. This was manifested by a decrease in the deuterium order parameter SCD as well as an increase in the membrane area. Disordering of the membrane suggested DMI to destabilize cholesterol-rich membrane domains (rafts) in cellular conditions. To relate the raft disrupting ability of DMI with novel biological relevance, we studied the intracellular effect of DMI using canine parvovirus (CPV), a virus known to interact with endosomal membranes and sphingomyelin, as an intracellular probe. DMI was found to cause retention of the virus in intracellular vesicular structures leading to the inhibition of viral proliferation. This implies that DMI has a deleterious effect on the viral traffic. As recycling endosomes and the internal vesicles of multivesicular bodies are known to contain raft components, the effect of desipramine beyond the plasma membrane step could be caused by raft disruption leading to impaired endosomal function and possibly have direct influence on the penetration of the virus through an endosomal membrane.

    2011-01-01

    We use atom-scale molecular dynamics simulations to clarify the role of glycosphingolipids in the dynamics of cholesterol-rich lipid rafts. To this end, we consider lipid membranes that contain varying. amounts of galactosylceramide (GalCer), sphingomyelin, cholesterol, and phosphatidylcholine....... The results indicate that increasing the portion of GalCer molecules greatly slows down the lateral diffusion, Only 5-10 mol % of GalCer causes a decrease of almost an order of magnitude compared to corresponding membranes without GalCer. The slowing down is not related to interdigitation, which becomes...... weaker with increasing GalCer concentration. Instead, the decrease in diffusion is found to correlate with the increasing number of hydrogen bonds formed between GalCer and the phospholipid molecules, which is also observed to have other effects, such as to increase the friction between the membrane...

    GPI-Anchored proteins (GPI-APs) can be exogenously transferred onto bilayer membranes both in vivo and in vitro, while the mechanism by which this transfer process occurs is unknown. In this work, we used atomistic molecular dynamics simulations and free energy calculations to characterize the essential influence of cholesterol on insertion of the GPI anchors into plasma membranes. We demonstrate, both dynamically and energetically, that in the presence of cholesterol, the tails of GPI anchors are able to penetrate inside the core of the lipid membrane spontaneously with a three-step mechanism, while in the absence of cholesterol no spontaneous insertion was observed. We ascribe the failure of insertion to the strong thermal fluctuation of lipid molecules in cholesterol-free bilayer, which generates a repulsive force in entropic origin. In the presence of cholesterol, however, the fluctuation of lipids is strongly reduced, thus decreasing the barrier for the anchor insertion. Based on this observation, we propose a hypothesis that addition of cholesterol creates vertical creases in membranes for the insertion of acyl chains. Moreover, we find that the GPI anchor could also spontaneously inserted into the boundary between cholesterol-rich and cholesterol-depleted domains. Our results shed light on the mechanism of cholesterol-mediated interaction between membrane proteins with acyl chain and plasma membranes in living cells.

    Converging evidence highlights that lipid metabolism plays a key role in ALS pathophysiology. Dyslipidemia has been described in ALS patients and may be protective but peripheral lipoprotein subclasses have never been studied. We collected sera from 30 ALS patients and 30 gender and age-matched controls. We analyzed 11 distinct lipoprotein subclasses by linear polyacrylamide gel electrophoresis (Lipoprint, Quantimetrix Corporation, USA). We also measured lipoprotein (a), apolipoprotein B, and apolipoprotein E levels. ALS patients had significant higher total cholesterol, HDL-cholesterol, and LDL-cholesterol levels than controls (pALS patients than controls. Our preliminary work confirmed the association between ALS and dyslipidemia. The low IDL-B levels may explain the hepatic steatosis frequently reported in ALS. The high levels of the cholesterol-rich LDL-1 subfraction is consistent with previously reported hypercholesterolemia. This study describes, for the first time, the distribution of serum lipoproteins in ALS patients, with low IDL-B and high LDL-1 subfraction level. Copyright © 2017 Elsevier B.V. All rights reserved.

    Systemic Sclerosis (SSc) is a systemic connective tissue disease. In this study, we compared the serum Homocystein (Hcy) level between patients with SSc and normal control group. The current study was conducted to determine whether serum Hcy levels are elevated in SSc patients and whether there is any correlation between Hcy levels and RP, Gastro intestinal and lung involvement. Forty one patients who fulfilled the diagnostic criteria for SSc (39 females and 5 males) and Forty four community-based healthy individuals (sex and age matched) were enrolled in to the study. Serum Hcy, vitamin B12, and folate levels were determined. Thirty three patients (70.45%) had GI involvement, twenty two patients (50%) had lung involvement and twenty seven patients (61.36%) had Raynaud's phenomena. Mean serum Hcy level in control group was 22.78 ± 6.018 μmol/L and in case group was 19.43 ± 7.205 μmol/L, shows that the serum Hcy level in control group was significantly higher than patients (P = 0.020). Serum Hcy level is significantly lower in SSc patients than in control group. There is no statistically significant correlation between serum Hcy level and organ involvements.

    The aim of the study was to determine the blood serum sulfated glycosaminoglycans (GAGs) and hyaluronic acid (HA) concentration of Graves' disease patients before treatment and after attainment of the euthyroid state. The study was carried out on the blood serum obtained from 17 patients with newly recognised Graves' disease and from the same patients after attainment of the euthyroid state. Graves' patients had not any clinical symptoms neither of ophthalmopathy nor pretibial myxedema. GAGs were isolated from the blood serum by the multistage extraction and purification using papaine hydrolysis, alkali elimination, as well as cetylpyridium chloride binding. Total amount of GAGs was quantified by the hexuronic acids assay. HA content in obtained GAGs sample was evaluated by the ELISA method. Increased serum concentration of sulfated GAGs in non-treated Graves' disease patients was found. Similarly, serum HA level in untreated patients was significantly elevated. The attainment of euthyroid state was accompanied by the decreased serum sulfated GAGs level and by normalization of serum HA concentration. In conclusion, the results obtained demonstrate that the alterations of GAGs metabolism connected with Graves' disease can lead to systemic changes of the extracellular matrix properties.

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

    The architecture of a biological membrane hinges upon the fundamental fact that its properties are determined by more than the sum of its individual components. Studies on model membranes have shown the need to characterize in molecular detail how properties such as thickness, fluidity, and macroscopic bending rigidity are regulated by the interactions between individual molecules in a non-trivial fashion. Simulation-based approaches are invaluable to this purpose but are typically limited to short sampling times and model systems that are often smaller than the required properties. To alleviate both limitations, the use of coarse-grained (CG) models is nowadays an established computational strategy. We here present a new CG force field for cholesterol, which was developed by using measured properties of small molecules, and can be used in combination with our previously developed force field for phospholipids. The new model performs with precision comparable to atomistic force fields in predicting the properties of cholesterol-rich phospholipid bilayers, including area per lipid, bilayer thickness, tail order parameter, increase in bending rigidity, and propensity to form liquid-ordered domains in ternary mixtures. We suggest the use of this model to quantify the impact of cholesterol on macroscopic properties and on microscopic phenomena involving localization and trafficking of lipids and proteins on cellular membranes.

    Caseins, the main milk proteins, interact with colloidal calcium phosphate to form the casein micelle. The mesostructure of this supramolecular assembly markedly influences its nutritional and technological functionalities. However, its detailed molecular organization and the cellular mechanisms involved in its biogenesis have been only partially established. There is a growing body of evidence to support the concept that αs1-casein takes center stage in casein micelle building and transport in the secretory pathway of mammary epithelial cells. Here we have investigated the membrane-associated form of αs1-casein in rat mammary epithelial cells. Using metabolic labelling we show that αs1-casein becomes associated with membranes at the level of the endoplasmic reticulum, with no subsequent increase at the level of the Golgi apparatus. From morphological and biochemical data, it appears that caseins are in a tight relationship with membranes throughout the secretory pathway. On the other hand, we have observed that the membrane-associated form of αs1-casein co-purified with detergent-resistant membranes. It was poorly solubilised by Tween 20, partially insoluble in Lubrol WX, and substantially insoluble in Triton X-100. Finally, we found that cholesterol depletion results in the release of the membrane-associated form of αs1-casein. These experiments reveal that the insolubility of αs1-casein reflects its partial association with a cholesterol-rich detergent-resistant microdomain. We propose that the membrane-associated form of αs1-casein interacts with the lipid microdomain, or lipid raft, that forms within the membranes of the endoplasmic reticulum, for efficient forward transport and sorting in the secretory pathway of mammary epithelial cells.

    Irisin has been proposed to regulate metabolic diseases such as obesity, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of this study was to evaluate the serum irisin level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and topical treatment. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after two weeks of therapy. Serum irisin concentrations were examined by enzyme-linked immunosorbent assay (ELISA). The results were correlated with psoriasis area and severity index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and effectiveness of topical treatment. Irisin serum levels were insignificantly increased in psoriatic patients in comparison to the controls (p = 0.38). No significant correlations between investigated adipokine and several indicators of metabolic disorders, nor BMI (p = 0.37) or PASI (p = 0.5) were found. Significant positive correlations with C-reactive protein (CRP) (0.009), lipocalin-2 (p = 0.02), age (p = 0.02) and disease duration (p = 0.008) were noted. After topical treatment, serum irisin level did not significantly change (p = 0.31), despite clinical improvement. Irisin might be a marker of inflammation in psoriatic patients, but may not be a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of antipsoriatic treatment.

    It has been established that overproduction of reactive oxygen species (ROS) occurs during hemodialysis causing oxidation of proteins. Alpha-1-antitrypsin is the major circulating anti-protease which contains methionine in the active site. The aim of the present study was to measure the level of serum trypsin inhibitory capacity (sTIC) in hemodialysis patients. This case-control study was performed in 52 hemodialysis patients and 49 healthy controls. sTIC was measured by enzymatic assay. The sTIC was significantly (P< 0.001) lower in hemodialysis patients (1.87 + - 0.67 micron mol/min/mL) than healthy controls (2.83 + - 0.44 micron mol/min/L). Reduction of sTIC may be due to the oxidation of methionine residue in the reactive site of alpha-1 antitrypsin. (author)

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

    Lipid rafts have been extensively studied and shown to be involved in many cancers, including breast cancer. However, the exact role of lipid rafts in the migration of breast cancer cells remains unclear. This study was designed to examine lipid rafts (cholesterol) in the plasma membrane of breast cancer cells (MDA-MB-231 and MCF-7) and normal breast epithelial cells (MCF-10A) through generalized polarization values, and further investigate the role of cholesterol-rich lipid rafts in the migration of breast cancer cells. The results showed that the plasma membrane in breast cancer cells was more orderly than that in normal epithelial cells; this was correlated with expression changes of matrix metallopeptidase 9 (MMP-9) and urokinase-type plasminogen activator receptor (uPAR), the markers of cancer cell migration. Moreover, the breast cancer cells were more sensitive to the reagent that induced cholesterol depletion than the normal breast epithelial cells, while the capacity of cancer cells to migrate decreased significantly according to changes in MMP-9 and uPAR expression. To our best knowledge, this is the first demonstration of the relationship between cholesterol-rich lipid rafts and the migration of breast cancer cells; it could be useful for the prevention of breast cancer and early treatment through reduction of the level of cholesterol in the plasma membrane of the cells.

    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

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

    Full Text Available Objectives: Adrenal insufficiency is an uncommon cause of hyponatraemia that should not be overlooked due to the severe consequences of an Addisonian crisis. Using the laboratory database of a large teaching hospital, we have explored the relationship between serum sodium and serum cortisol, and have estimated the frequency of hypoadrenalism in severely hyponatraemic patients. Design and methods: Data were gathered over a 23 month period from the Laboratory Information Management System at the Leeds Teaching Hospitals NHS Trust for instances where serum sodium and cortisol had been measured on a single sample. Data were also gathered over the same time period for all patients with severe hyponatraemia (serum sodium ≤120 mmol/L in order to determine the frequency of cortisol requesting and the incidence of adrenal insufficiency. Results: Analysis of the data (n=3268 patients revealed a trend showing higher cortisol concentrations in patients who were severely hypo- or hypernatraemic. The median cortisol concentration for patients with sodium ≤110 mmol/L was 856 nmol/L, and there was a gradual decrease in cortisol over the sodium range ≤110–150 mmol/L (Rs =−0.323, p<0.0001. Patients with sodium ≥151 mmol/L had a median cortisol of 725 nmol/L. 42% of the 978 patients with serum sodium ≤120 mmol/L had serum cortisol measured within two weeks, of whom 1.7% were diagnosed with adrenal insufficiency. Conclusions: This dataset shows rising cortisol in response to hypo- or hypernatraemia, in keeping with the stress response to illness. The data show that adrenal insufficiency is a rare cause of hyponatraemia which may be overlooked. Keywords: Serum, Sodium, Cortisol, Adrenal insufficiency

    Serum hyaluronan levels are increased in dialysis patients. We evaluated several factors that influence serum hyaluronan levels in 184 patients on chronic hemodialysis (duration 2.3 +/- 2.3 [SD] years). The levels were higher than normal in the whole group and in a subgroup of 133 patients without chronic infection, liver disease, or rheumatoid arthritis (215 +/- 19 and 205 +/- 22 microg/L, respectively). There was a tendency for the levels to be higher in a subgroup of patients with hepatitis c virus (HCV) infection. There was no correlation between hyaluronan levels, alanine aminotransferase (ALT), and duration or dose of dialysis. A weak but highly significant negative correlation between serum albumin levels and serum hyaluronan and ferritin levels was seen. The data suggest that chronic inflammation may explain, at least in part, the increased hyaluronan levels found in chronic dialysis patients.

    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/m 2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m 2 (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

    Vitamin D is increasingly associated with the pathology of cognition and mental illness. Vitamin D receptors have been detected on neurons that regulate behavior. To assess vitamin D serum concentrations in patients with major depression and schizophrenia as compared to healthy controls and to determine if a correlation exists between serum levels of vitamin D and disease activity. We recruited 50 patients with schizophrenia and compared them to 33 patients with major depression and 50 controls with no major psychopathology. The Positive and Negative Syndrome Scale (PANSS) for schizophrenia and the Hamilton Depression scale for depression were administered on the same day the blood samples were drawn. We used LIAISON 25-OH vitamin D (DiaSorin) immunoassay to measure serum concentrations of 25-OH vitamin D. Lower serum vitamin D concentrations were detected among patients with schizophrenia (15.0 +/- 7.3 ng/ml) compared to patients with depression (19.6 +/- 8.3 ng/ml) and to controls (20.2 +/- 7.8 ng/ml, P vitamin D levels. Serum vitamin D levels were lower in patients with schizophrenia as compared to patients with depression and to healthy controls. No correlation was found between serum concentration and disease activity. Additional studies are needed to elucidate the role of vitamin D in the autoimmune mechanism and in the pathogenesis of schizophrenia.

    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.

    - Bilirubin has strong anti-inflammatory and antioxidative stress action. Progression of inflammation involving arteries is a crucial activator in pathogenesis of Takayasu arteritis (TA). - To investigate the relationship between serum bilirubin and TA. - Our study involved 115 consecutive TA patients. Patients with active-phase disease were followed and received prednisone therapy. - Lower concentrations of serum bilirubin were detected in TA patients compared with healthy subjects (0.6 ± 0.31 versus 0.7 ± 0.22 mg/dL, P = .02). Serum bilirubin concentrations in active TA patients were lower than those in inactive patients (0.5 ± 0.20 versus 0.8 ± 0.32 mg/dL, P bilirubin correlated positively with total protein (r = 0.193, P = .04) and negatively with C-reactive protein and erythrocyte sedimentation rate (r = -0.213, P = .03, and r = -0.532, P bilirubin was associated with a 1.10 times increase in the odds for TA compared with the controls (odds ratio = 0.913, 95% CI, 0.856-0.974; P = .006). Serum bilirubin was correlated with erythrocyte sedimentation rate (β = -0.170, P bilirubin in predicting active TA patients was 0.802. Serum bilirubin levels were found to be significantly increased after prednisone treatment (0.5 ± 0.20 versus 0.7 ± 0.15 mg/dL, P = .002). - Lower serum bilirubin levels are associated with TA, and serum bilirubin may be influenced by prednisone therapy in active TA patients. Serum bilirubin levels in TA patients correlate negatively with erythrocyte sedimentation rate.

    Studies on serum and gastrointestinal secretion from CF patient is suggest that defective accumulation of mucus in gastrointestinal tract and excessive amount of a protease resistant peptides in serum are related to the abnormal activity of enzymes responsible for fatty acylation of proteins. Here, the authors investigated the fatty acyltransferase activities in serum of normal and CF patients. A 15μl of serum was mixed with 0.85 nmol [ 14 C]palmitoyl CoA, 200μg of serine and threonine and incubated at 37 0 C for 30 min. The incubates were immediately frozen, dried extracted with C/M and chromatographed in chloroform/methanol/water. The incorporation of [ 14 C]palmitate was determined using linear radioscanner and authoradiography. The results of HPTLC revealed that CF serum in addition of ACAT and LCAT contained enzymes responsible for the transfer of [ 14 C]palmitate to monoacylphosphoglycerides, and serine and threonine. In normal serum the formation of a small amount of palmitoyl serine and palmitoyl threonine was also observed but the acylation of monoacylphosphoglycerides was not detectable. The authors conclude that in cystic fibrosis the abnormal fatty acyltransferases are responsible for the occurrence of protease resistant glycoprotein, unusual peptides in serum and possibly for the modification of membrane proteins and lipids

    Adiponectin is an adipocytokine secreted from white adipose tissue. Serum level of adiponectin has been shown to be reduced in several disease states like obesity and diabetes. Hypoadiponectinemia has also been included in the list of newer risk factors for Coronary Artery Disease (CAD). In this analytical cross-sectional study serum adiponectin level was measured by Enzyme Linked Immunosorbant Assay (ELISA) in 60 cases of coronary artery disease (CAD) (both sexes, aged 40-60 yrs) and 60 healthy controls. Low levels of adiponectin were seen in CAD patients as well as controls. These levels were lower as compared to western standards. Our study conforms to the previous observation of lower serum adiponectin levels in South Asians compared to the western standards. Serum adiponectin level should be considered in the laboratory work-up of CAD patients. (author)

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

    Full Text Available Introduction : Systemic sclerosis (SSc is achronic connective tissue disease characterized by microangiopathy with inadequate angiogenesis. Angiostatin (AS is a potent antiangiogenic factor specifically inhibiting proliferation and inducing apoptosis of vascular endothelial cells. Aim : To evaluate the level of angiostatin in the serum of patients with SSc. Material and methods : Serum levels of AS were measured in 20 SSc patients and 12 healthy controls. Results : A statistically significant difference in the serum levels of AS in SSc patients was observed compared to the control group (636.51 vs. 869.20 ng/ml; p = 0.012. Significant correlations between limited and disseminated SSc (lSSc/dSSc were not found, however, a difference between lSSc and the control group was demonstrated (620.00 vs. 869.20 ng/ml; p = 0.011. The serum level of AS was not associated positively with organ changes caused by SSc. However, a statistically significant lower serum level of AS was observed in patients with SSc and no esophageal (p = 0.008 or pulmonary changes (p = 0.007 compared to the control group. Conclusions : Our results reveal significant differences in AS level in SSc patients compared to the healthy controls, and suggest that a low level of AS may occur as a result of impaired angiogenesis.

    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.

    To evaluate the influence of serum Lp(a) concentration on hypertension in patients with diabetes mellitus (DM) and under treatment with oral hypoglycemic agents or insulin injections, we studied 122 patients, 82 females and 40 males with a mean age of 63+-10 years and duration of DM and HTN of 7.4+-5.8 and 3.2+-4.6 years, respectively. The mean systolic and diastolic blood pressure (BP) was 138+-23 mmHg and 83+-12mmHg, respectively. In this cross-sectional study, we measured serum lipoprotein (a) (Lp(a), glycosilated hemoglobin (HbA1c) and other lipids while the patients were receiving either oral hypoglycemic agents or insulin. In addition, body mass index (BMI) and creatinine clearance (CrCL) were assessed. The mean serum Lp(a) was 22.2+-24.7 mg/dl (median: 18.3 mg/dl), and serum Lp(a) levels >30 mg/dl was found in 29(23.8%) patients. There were significant positive correlations of duration of DM and duration of hypertension, and serum Lp(a) levels with of systoli and diastolic levels of BP. However, a significant inverse correlation of serum Lp(a) with CrCl were observed. This study suggests that kidney function is an independent determination of Lp(a) and HTN in diabetic patients. Furthermore Lp(a) in diabetic patients may have important implications for the increased susceptibility to vascular diseases in these patients. (author)

    Chalazion is a chronic, localized lipogranulomatous inflammation of the sebaceous glands of the lids. Chalazion occurs often secondary to blockage of the sebaceous gland ducts. Some studies have reported vitamin A deficiency as a risk factor for chalazion. In this study, we determined the serum levels of vitamin A in patients with chalazion. The study involved a total of 107 subjects (52 patients with chalazion and 55 control healthy subjects). The study was conducted at the Ophthalmology Clinics of Imam Khomeini Hospital, Ahwaz Jundishapur University of Medical Sciences, Ahwaz, Iran between September 2014 and February 2015. The subjects were divided into three groups according to age: 7-12 years old, 13-19 years old, and more than 19 years old. Patients were further divided into four subgroups based on the type of chalazion: single, multiple, primary, and recurrent. Blood samples were collected and the serum was tested for levels of vitamin A using high-performance liquid chromatography (HPLC). The average serum vitamin A levels in patients with chalazion in the age groups of 7-12 and 13-19 years were significantly lower than in their control counterparts. Serum vitamin A levels in patients with recurrent, multiple chalazia were significantly lower than in patients with primary, multiple chalazia (P = 0.026) and patients with a recurrent, single chalazion (P = 0.029). In conclusion, chalazion could be one of the ocular presentations of vitamin A deficiency.

    To determine the serum and intraerythrocyte concentrations of vasoactive ions in patients of diabetes mellitus of either gender with hypertension. The study was conducted on 48 volunteers. Out of 48, 24(12 men and 12 women) were hypertensive patients with diabetes mellitus. Remaining (12 men and 12 women) were normal healthy subjects. Biochemical estimations were done by flame photometry and spectrophotometry. Data were analyzed by Two-way ANOVA followed by Newman-Keuls test. A decrease in serum concentrations of sodium, calcium, magnesium, phosphorus, chloride and intraerythrocyte potassium and an increase in the levels of glucose, haematocrit and intraerythrocyte sodium was observed in both male and female patients with diabetes mellitus and hypertension. No significant changes were observed in serum potassium levels. The results suggest that dysregulations of electrolyte balance caused by hyperinsulinemia or altered glucose metabolism may lead to hypertension. (author)

The mean serum ghrelin level was 45.41 ± 22.41 in the psoriasis group and 29.92 ± 14.65 in the healthy control group. Serum ghrelin level was significantly higher in the psoriasis group compared with the controls (P=0.01. The mean ghrelin level in patients with a lower PASI score was significantly higher than in those with a higher PASI score (P=0.02. Conclusion. The present study was performed to determine the effects of ghrelin in psoriasis patients. We found a negative correlation between severity of psoriasis and ghrelin level. Larger and especially experimental studies focusing on correlation of immune system-ghrelin levels and severity of psoriasis may be valuable to clarify the etiopathogenesis of the disease.

    Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

    Drug addiction is a complex problem which leads to many somatic, psychic and social diseases. It is accompanied by the disturbed metabolism of various macro and micronutrients. The aim of this study was to assess serum magnesium concentration in drug-addicted patients and analyze whether Human Immunodeficiency Virus (HIV) infection and methadone treatment affect the level of serum magnesium in these patients. The examination was conducted in a group of 83 people - patients of Szczecin-Zdroje Psychiatric Hospital (Poland). They were 21 to 49 years old, and the mean age was 32 +/- 7 years. The control group consisted of 81 healthy individuals. Flame atomic-absorption spectrometry method was used to determine the magnesium concentration. The total serum magnesium concentration was calculated for the whole patient group, subgroups of women and men, a subgroup of people infected with HIV, and a subgroup receiving methadone substitution treatment. How magnesium behaves depending on age and addiction period, was checked. The mean concentration of magnesium in blood serum of the patients examined was 0.57 mmol/L, which was significantly lower than in the control group. In the subgroup of men it was 0.57 mmol/L, and in the subgroup of women - 0.55 mmol/L; the differences were not statistically significant. In the patient group nobody had the appropriate magnesium concentration in blood serum. No significant correlation was found between the magnesium concentration, age of the patients and addiction period. In the subgroup of seropositive people the mean concentration of magnesium was 0.55 mmol/L, and in the subgroup of non-infected patients - 0.58 mmol/L; the difference was not statistically significant. The mean concentration of magnesium in the subgroup treated with methadone was 0.59 mmol/L, and in the subgroup not involved in this type of therapy - 0.55 mmol/L; it was not a statistically significant difference.

    Psoriasis is a common chronic and recurrent inflammatory skin disorder characterized by hyperproliferation of keratinocytes and infiltration of T cells, monocytes/macrophages and neutrophils into dermal and epidermal layers of the skin. The prevalence of cardiovascular disorders in these patients is remarkably higher compared to normal individuals, which seems to be associated with the hyperlipidemia. This study was designed and conducted to investigate the serum lipid profile in psoriatic patients and its association with the severity of disease. This case-control study was performed on 50 plaque-type psoriasis patients and 50 healthy individuals as control, matched for age and sex. Blood samples were collected after 14 h fasting. Serum triglyceride, cholesterol and lipoproteins were assayed using the standard kit (made by Pars Azmon Co. Iran). Certain parameters, including serum triglyceride, cholesterol, low density lipoprotein (LDL), and very low density lipoprotein (VLDL), were significantly higher in the case group compared to the controls (P lipoprotein (HDL) was significantly lower in the former (P < 0.001). In addition, there was a significant relationship between severity of psoriasis and serum lipid profile. The results have revealed the higher plasma level of lipids in psoriatic patients. This may elevate the risk of atherosclerosis, particularly cardiovascular disorders. Therefore, from the epidemiological point of view, screening psoriatic patients, particularly those with severe psoriasis, is recommended.

    The diagnosis of borderline hyperthyroidism is difficult. A sensitive radioimmunoassay capable of detecting subnormal levels of serum TSH may be of value in confirming this diagnosis because of the suppressed pituitary function in this disease state. This sensitive assay may also be useful in monitoring the suppression of pituitary function in thyroid cancer patients receiving thyroid hormone therapy. A sensitive radioimmunoassay capable of detecting serum TSH levels as low as 0.25 μU/m1 with coefficients of variation less than 17.2% was used to measure serum TSH levels in 80 healthy subjects, 44 hyperthyroid patients, and 25 athyrotic thyroid cancer patients on daily suppressive doses of thyroxine. All healthy subjects had detectable TSH levels with a mean value of 1.17 and two standard deviation ranges of 0.41 - 2.70 μU/m1 (lognormal distribution). Although the mean +-1 SEM value of 0.63 +- 0.003 μUm1 for hyperthyroid patients and 0.76 +- 0.08 μU/ml for thyroid cancer patients were significantly lower than that of healthy subjects (t-test, p<0.05), subnormal levels of serum TSH were found in only 28.6% (12/42) and 24% (6/25) of hyperthyroid and thyroid cancer patients, respectively. TSH stimulation tests performed in 6 of the cancer patients all gave suppressed responses. Because of considerable overlap, serum TSH levels alone cannot distinguish hyperthyroidsm from euthyroidism. However, a sensitive TSH radioimmunoassay such as the one described here may be of value in evaluating the extent of pituitary suppression in thyroid cancer therapy

    We have reviewed our experience with the management of patients with thyroid cancer to assess the potential benefits of employing the serum thyroglobulin assay in patient management programs and to determine the optimal conditions for this application. Serum thyroglobulin levels were found to be more reliable when obtained from hypothyroid patients. Levels of thyroglobulin greater than 10 ng/mL appeared to be abnormally elevated in both thyroidectomized patients prior to radioactive iodine therapy (group 1) and in thyroidectomized patients after radioactive iodine therapy (group 2). Elevated thyroglobulin levels were found to be useful indicators of the presence of metastatic disease, whereas normal thyroglobulin levels were reliable indicators of the absence of metastases. In group 1 patients, elevated thyroglobulin levels reliably predicted the presence of important total body scan uptake. In group 2 patients, normal thyroglobulin levels reliably predicted the absence of total body scan uptake. The serum thyroglobulin assay can substantially reduce the need for repetitive total body scanning in the follow-up of group 2 patients with thyroid cancer

    To find out the prevalence of Vitamin-D deficiency in conditions other than osteomalcia and rickets in our part of the world. Only those patients were included who had any structural or biochemical changes in the body. Serum Vitamin-D level of all patients was sent for estimation from a single reputable laboratory, apart from serum calcium, phosphorus, alkaline phosphatase and routine blood investigations. All data was collected and processed on SPSS Version 10. Of the total 79 patients, 58(73%) were females and 21(27%) males. Minimum age was one year and maximum 90 years, with a mean age of 41.91 and standard deviation of 19.1. Majority of the patients were seen in the 4th, 5th and 6th decades of life, and most of them were house wives. The serum Vitamin-D level was found low in 73(92%) patients and the most severe form of deficiency was seen in patients with tuberculosis. Vitamin-D deficiency was seen in 92% of our patients, belonging to all age groups and suffering from different diseases. (author)

    Full Text Available Aims: Leptin is one of the most important fat-derived hormones. Several studies have shown that serum leptin levels in systemic inflammatory diseases are reduced. The aim of this study was to evaluate the serum leptin levels in three groups: patients with active pulmonary tuberculosis (TB, patients with non-pulmonary infections (acute pneumonia and normal people. Materials & Methods: In this cross-sectional study, in 2010, 40 patients with active pulmonary TB (case group and 40 patients with non-pulmonary infections (positive control group admitted to Boo-Ali hospital in Zahedan and 40 healthy subjects (negative control group were selected using easy access and serum leptin levels were evaluated by ELISA. Data were analyzed by SPSS 18 software and one-way ANOVA. Findings: The mean of serum leptin levels in patients with non-pulmonary infections (p=0.030 and in patients with active pulmonary TB (p=0.004 were significantly lower than normal group, but the mean of serum leptin levels in patients with active pulmonary TB and patients with non-pulmonary infections were not significantly different (p=0.555. Conclusion: Serum leptin levels are lower in patients with active pulmonary tuberculosis and in patients with non-pulmonary infections than in normal people, but there is no difference between patients with active pulmonary tuberculosis and patients with non-pulmonary infections. Therefore, serum leptin levels are not an appropriate marker for the differentiation of active pulmonary tuberculosis from pulmonary infections (acute pneumonia.

    In this paper, FTIR spectroscopy was applied to compare the serum from leukemia patients with the serum from healthy persons. IR spectra of leukemia patients' serum were similar with IR spectra of healthy persons' serum, and they were all made up of proteins, lipids and nucleic acids, etc. In order to identify leukemia patients' serum and healthy persons' serum, the H1075/H1542, H1045/H1467, H2959/H2931 ratios were measured. The H2959/H2931 ratio had the highest significant difference among these ratios and might be a useful factor for identifying leukemia patients' serum and healthy persons' serum. Furthermore, from curve fitting, the RNA/DNA (A1115/A1028) ratios were observed to be lower in leukemia patients' serum than those in healthy persons' serum. The results indicated FTIR spectroscopic study of serum might be a useful tool in the field of leukemia research and diagnosis.

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

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

    Full Text Available Multiple sclerosis (MS is a chronic inflammatory disease of the central nervous system (CNS. It is characterized by loss of myelin, the fatty tissue that surrounds and protects nerve fibres allowing them to conduct electrical impulses. Recent data indicate that oxidative stress (OS plays a major role in the pathogenesis of multiple sclerosis (MS. The aim of this study was to estimate level of serum total antioxidative capacity in patients with multiple sclerosis. Our cross-sectional study included 33 patients with MS and 24 age and sex matched control subjects. All our patients had a Poser criteria for definite diagnostic categories of multiple sclerosis. Serum total antioxidant capacity (TAC was measured by quantitative colorimetric determination, using Total antioxidant Capacity-QuantiCromAntioxidant Assay Kit (BioAssay systems, USA; DTAC-100. Mean serum TAC in multiple sclerosis group of patients was 119.2 mM Trolox equivalents and was significantly lower (p<0.001 compared to the control group of subjects (167.1 mM Trolox equivalents. Our results showed that oxidative stress plays an important role in pathogenesis of multiple sclerosis. This finding, also, suggests the importance of antioxidants in diet and therapy of MS patients.

    A reliable estimate of survival is important as it may impact treatment choice. The objective of this study is to identify serum autoantibody biomarkers that can be used to improve prognostication for patients affected with head and neck squamous cell carcinoma (HNSCC). Prospective cohort study. A panel of 130 serum biomarkers, previously selected for cancer detection using microarray-based serological profiling and specialized bioinformatics, were evaluated for their potential as prognostic biomarkers in a cohort of 119 HNSCC patients followed for up to 12.7 years. A biomarker was considered positive if its reactivity to the particular patient's serum was greater than one standard deviation above the mean reactivity to sera from the other 118 patients, using a leave-one-out cross-validation model. Survival curves were estimated according to the Kaplan-Meier method, and statistically significant differences in survival were examined using the log rank test. Independent prognostic biomarkers were identified following analysis using multivariate Cox proportional hazards models. Poor overall survival was associated with African Americans (hazard ratio [HR] for death = 2.61; 95% confidence interval [CI]: 1.58-4.33; P = .000), advanced stage (HR = 2.79; 95% CI: 1.40-5.57; P = .004), and recurrent disease (HR = 6.66; 95% CI: 2.54-17.44; P = .000). On multivariable Cox analysis adjusted for covariates (race and stage), six of the 130 markers evaluated were found to be independent prognosticators of overall survival. The results shown here are promising and demonstrate the potential use of serum biomarkers for prognostication in HNSCC patients. Further clinical trials to include larger samples of patients across multiple centers may be warranted. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  5. SERUM ELECTROLYTES AND OUTCOME IN PATIENTS UNDERGOING ENDOSCOPIC GASTROSTOMY

    Directory of Open Access Journals (Sweden)

    Joana VIEIRA

    Full Text Available ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG is a gold standard for long term enteral feeding. Neurologic dysphagia and head/neck cancer are the most common indications for PEG as they can lead to protein-energy malnutrition and serum electrolyte abnormalities, with potential negative impact on metabolic balance. Refeeding syndrome may also be related with severe electrolyte changes in PEG-fed patients and contribute to poor prognosis. OBJECTIVE: This study aims to evaluate the changes in serum concentrations of the main electrolytes and its possible association with the outcome. METHODS: Retrospective study of patients followed in our Artificial Nutrition Clinic, submitted to PEG from 2010 to 2016, having head/neck cancer or neurologic dysphagia, who died under PEG feeding. Serum electrolytes (sodium, potassium, chlorine, magnesium, calcium and phosphorus were evaluated immediately before the gastrostomy procedure. Survival after PEG until death was recorded in months. RESULTS: We evaluated 101 patients, 59 with electrolyte alterations at the moment of the gastrostomy. Sodium was altered in 32 (31.7%, magnesium in 21 (20.8%, chlorine in 21 (20.8%, potassium in 14 (13.8%, calcium in 11 (10.9 % and phosphorus in 11 (10.9%. The survival of patients with low sodium (<135 mmol/L was significantly lower when compared to patients with normal/high values, 2.76 months vs 7.80 months, respectively (P=0.007. CONCLUSION: Changes in serum electrolytes of patients undergoing PEG were very common. More than half showed at least one abnormality, at the time of the procedure. The most frequent was hyponatremia, which was associated with significantly shorter survival, probably reflecting severe systemic metabolic distress.

    Luteinizing hormone-releasing hormone (LH-RH) agonists are the standard for androgen deprivation therapy (ADT) in prostate cancer (PCa) patients. Current guidelines recommend serum testosterone measurement to assess the efficacy of ADT and to define castration resistance. However, serum testosterone does not reflect the exclusive effect of castration due to its extratesticular production. The aim of this study is to analyze if serum LH reflects better than serum testosterone the activity of LH-RH agonists. Serum LH and serum testosterone were measured with chemiluminescent immunoassay (CLIA) in a cohort study of 1091 participants: 488 PCa patients "on LH-RH agonists", 303 "off LH-RH agonist" in whom LH-RH agonists were withdrawn, and 350 men with PCa suspicion "no LH-RH agonist" who never received LH-RH agonists. In a validation cohort of 147 PCa patients, 124 on "LH-RH agonists" and 19 "off LH-RH agonists", serum testosterone was also measured with liquid chromatography and tandem mass spectrometry (LC MSMS). The area under the curve (AUC) to distinguish patients "on versus off LH-RH agonists" was 0.997 for serum LH and 0.740 for serum testosterone, P < 0.001. The 97.5 percentile of serum LH in patients "on LH-RH agonists" was 0.97 U/L, been the most efficient threshold 1.1 U/L. The AUCs for serum LH, testosterone measured with CLIA and with LC MSMS, in the validation cohort, were respectively 1.000, 0.646 and 0.814, P < 0.001. The efficacy to distinguish patients "on versus off LH-RH agonists" was 98.6%, 78.3%, and 89.5% respectively, using 1.1 U/L as threshold for serum LH and 50 ng/dL for serum testosterone regardless the method. Serum LH is more accurate than serum testosterone regardless the method, to distinguish patients "on versus off LH-RH agonists". The castrate level of serum LH is 1.1 U/l. These findings suggest that assessment of LH-RH agonist efficacy and castration resistance definition should be reviewed.

    Intolerance to various foods, excluding bona fide coeliac disease and lactose intolerance, represents a growing cause of patient visits to allergy clinics.Histamine intolerance is a long-known, multifaceted clinical condition triggered by histamine-rich foods and alcohol and/or by drugs that liberate histamine or block diamine oxidase (DAO), the main enzyme involved in the metabolism of ingested histamine. Histamine limitation diets impose complex, non-standardized restrictions that may severely impact the quality of life of patients. We retrospectively evaluated 14 patients who visited allergy outpatient facilities in northern Italy with a negative diagnosis for IgE-mediated food hypersensitivity, coeliac disease, conditions related to gastric hypersecretion, and systemic nickel hypersensitivity, and who previously underwent a histamine limitation diet with benefits for their main symptoms. Serum diamine oxidase levels and the clinical response to diamine oxidase supplementation were investigated. We found that 10 out of 14 patients had serum DAO activityintolerance. Moreover, 13 out of 14 patients subjectively reported a benefit in at least one of the disturbances related to food intolerances following diamine oxidase supplementation. The mean value (±SD) of diamine oxidase activity in the cohort of patients with histamine intolerance symptoms was 7.04±6.90 U/mL compared to 39.50±18.16 U/mL in 34 healthy controls (P=0.0031). In patients with symptoms triggered by histamine-rich food, measuring the serum diamine oxidase activity can help identify subjects who can benefit from a histamine limitation diet and/or diamine oxidase supplementation.Properly designed, controlled studies investigating histamine intolerance that include histamine provocation are indispensable for providing insights into the area of food intolerances, which are currently primarily managed with non-scientific approaches in Italy. © The Author(s) 2015.

    Abstract Follistatin is a glycoprotein with various biologic functions that plays a role in adipocyte differentiation, muscle stimulation, anti-inflammation, and energy homeostasis. Thyroid hormones influence energy expenditure, glucose, and lipid metabolism. The association between serum follistatin level and thyroid function statuses has seldom been evaluated. The objectives of this study were to compare serum follistatin concentrations in different thyroid function statuses and to evaluate the associations between serum follistatin and free thyroxine (fT4) levels. In this study, 30 patients with hyperthyroidism (HY group) and 30 euthyroid individuals (EU group) were recruited. The patients of HY group were treated with antithyroid regimens as clinically indicated, whereas no medication was given to EU group. The demographic and anthropometric characteristics, biochemical data, serum levels of follistatin, and thyroid function of both groups at baseline and at the 6th month were compared. Data of all patients were pooled for the analysis of the associations between the levels of follistatin and fT4. At baseline, the HY group had significantly higher serum follistatin levels than the EU group (median [Q1, Q3]: 1.81 [1.33, 2.78] vs 1.13 [0.39, 1.45] ng/mL, P hyperthyroidism had higher serum follistatin levels, which decreased after receiving antithyroid treatment. In addition, the serum follistatin concentrations were positively associated with serum fT4 levels in patients with hyperthyroidism or euthyroidism. PMID:26844494

    Hilar cholangiocarcinoma is a devastating malignancy with incidence varying by geography and other risk factors. Rapid progression of disease and delays in diagnosis restrict the number of patients eligible for curative therapy. The objective of this study was to determine prognostic factors of overall survival in all patients presenting with hilar cholangiocarcinoma. All adult patients with histologically confirmed hilar cholangiocarcinoma from 2003 to 2013 were evaluated for predictors of survival using demographic factors, laboratory data, symptoms and radiological characteristics at presentation. A total of 116 patients were identified to have pathological diagnosis of hilar cholangiocarcinoma and were included in the analysis. Patients with a serum albumin level >3.0 g/dL (P 3.0 g/dL was identified as an independent predictor of overall survival (hazard ratio 0.31; 95% confidence interval 0.14-0.70) with a survival benefit of 44 weeks. This study was the largest analysis to date of prognostic factors in patients with hilar cholangiocarcinoma. A serum albumin level >3.0 g/dL conferred an independent survival advantage with a significantly greater length of survival. © The Author(s) 2016.

    Cholesterol-rich very low density lipoproteins (VLDL) from the homozygous Watanabe heritable hyperlipidemic (WHHL) rabbit induced marked cholesteryl ester accumulation in mouse peritoneal macrophages. This WHHL rabbit, an animal model of human familial hypercholesterolemia, has severe hypercholesterolemia, cutaneous xanthomas, and fulminant atherosclerosis due to the deficiency of the low density lipoprotein (LDL) receptor. When incubated with mouse peritoneal macrophages, the VLDL from WHHL rabbit (WHHL-VLDL) stimulated cholesteryl [ 14 C]oleate synthesis 124-fold more than did VLDL from the normal Japanese White rabbit (control-VLDL). The enhancement in cholesteryl ester synthesis and accumulation of WHHL-VLDL was due to the presence of a high affinity binding receptor site on the macrophage cell surface that mediated the uptake and lysosomal degradation of WHHL-VLDL. Competition studies showed that the uptake and degradation of 125 I-WHHL-VLDL was inhibited by unlabeled excess WHHL-VLDL and beta-migrating VLDL (beta-VLDL), but not LDL. Furthermore, the degradation of WHHL-VLDL was not blocked by either fucoidin, polyinosinic acid, or polyguanylic acid, potent inhibitors of the acetylated (acetyl)-LDL binding site, or by acetyl-LDL. These results suggest that macrophages possess a high affinity receptor that recognizes the cholesterol-rich VLDL present in the plasma of the WHHL rabbit and that the receptor which mediates ingestion of WHHL-VLDL seems to be the same as that for beta-VLDL and leads to cholesteryl ester deposition within macrophages. Thus, the uptake of the cholesterol-rich VLDL from the WHHL rabbit by macrophages in vivo may play a significant role in the pathogenesis of atherosclerosis in the WHHL rabbit

    Full Text Available background: This study aimed to determine serum Bisphenol A (BPA concentrations in patients with dilated cardiomyopathy (DCM as well as the association between serum BPA and several hormonal parameters in DCM patients compared with a healthy control group. Materials and methods: Eighty-eight DCM patients and 88 age- and gender-matched healthy controls were included. Serum BPA levels and several hormonal parameters (including total testosterone (T, sex hormone-binding globulin (SHBG and estradiol (E2 were measured by using corresponding ELISA Kits. The free androgen index (FAI was calculated by the formula: total T in nmol/L × 100/SHBG in nmol/L. Results: BPA levels in the total DCM group were significantly higher compared with that in the controls (6.9 ± 2.7 ng/mL vs. 3.8 ± 1.9 ng/mL, p < 0.001. Significant difference was also observed in SHBG and FAI between DCM patients and controls, (76.9 ± 30.9 nM/L vs. 41.0 ± 15.6 nM/L and 2.9 ± 3.5 vs.5.3 ± 2.6, respectively, both of p < 0.001. Similar trends were observed in the male and female subgroup. Mean T level was lower in DCM group than in control group (540.8 ± 186.0 pg/mL vs. 656.3 ± 112.9 pg/mL, p < 0.001. Linear regression analysis has shown that increasing serum BPA levels were statistically significantly associated with increased SHBG levels. However, no statistical difference was noted for E2. Conclusion: Our findings firstly demonstrated that BPA exposure increased in DCM patients compared with that in healthy controls, while FAI and T levels decreased. SHBG presented a positive association with BPA. It is concluded that hormone disorder induced by BPA exposure might be an environmental factor in the pathology of DCM.

    Among the pregnancy urinary tract infections, asymptomatic bacteriuria (ASB) is the most common one. Untreated ASB can progress to pyelonephritis in 30-50% of the patients and can also result in prematurity in 27% of the pregnancy so it needs immediate diagnosis and treatment. In this study, we wanted to evaluate procalcitonin levels, compared to other inflammatory in pregnant women with ASB. The study was designed between the period of January 2012 and February 2013 at Sakarya University School of Medicine, Department of Gynecology and Obstetrics. The study population included 30 pregnant patients with asymptomatic bacteriuria and 39 healthy pregnant controls. Mean age was 28 (SD, 5.5) of the study population; mean maternal weight was 70 (SD, 8) kilogram. There were no statically significant differences between the groups according to the routine biochemical parameters, but gestational age was significantly lower in the ASB group compared to the controls (20.4 vs 28.6, respectively; p 0.05 ng/ml and 21(70%) patients had negative procalcitonin levels (Chi-squrae, p treatment of the first ASB diagnosis. Procalcitonin levels were significantly higher in ASB group than the control group and serum procalcitonin levels were higher in pregnant women with recurrent ASB. This finding is an important result revealed that high procalcitonin level can predict the further urinary tract infection risk. Finally, serum procalcitonin levels were normal in healthy pregnant women while other inflammatory markers such as WBC, ESR and CRP levels were higher.

    Full Text Available Background: Lyme borreliosis (LB is a serious infectious disease. Carnitine plays a crucial role in metabolism and inflammatory responses. Carnitine may be important in improving neuronal dysfunction and loss of neurons. Aim: To evaluate serum carnitine concentration in adult patients with various clinical types of LB. Material/Methods: Groups: 1 patients with erythema migrans (EM, n=16, 2 neuroborreliosis (NB, n=10, 3 post-Lyme disease (PLD, n=22 and healthy controls (HC, n=32. Total (TC and free (FC carnitine were determined with the spectrophotometric method. Results: TC levels (44.9±10.4, 28.0±8.4, 35.9±15.6 μmol/L in the EM, NB and PLD patients were lower than in HC (54.0±11.4 μmol/L, p < 0.001. FC levels (32.7±7.7, 23.6±6.8, 26.3±11.2 μmol/L in the EM, NB and PLD patients were lower than in HC (40.5±7.6 μmol/L, p < 0.001. AC levels (12.2±5.2, 4.4±2.6, 9.6±7.4 μmol/L in the EM, NB and PLD patients were lower in the NB and PLD patients than in HC (13.5±8.40 μmol/L, p <0.001. AC/FC ratio was 0.31±0.14, 0.18±0.09, 0.39±0.33 in the EM, NB and PLD patients. Conclusions: LB patients exhibit a significant decrease of their serum carnitine concentrations. The largest changes were in the NB and PLD patients. To prevent late complications of the disease a possibility of early supplementation with carnitine should be considered. Further studies are required to explain the pathophysiological significance of our findings.

    provided by the EMIT tox test kits. As a consequence, decision limits for all three group tests in serum were lowered to near the detection limit: (table: see text) For quantitative tests the lower limits of quantification were: (table: see text) The working reagents were stable for at least 14 days at 4-8 degrees C. Calibration curves were stable over the expiration period of reconstituted original reagents (6-12 weeks), also when working reagents were prepared in aliquots from stored reconstituted reagents. Application of the newly adapted programme to serum samples of nearly two hundred patients showed it to be suitable for screening patients in which intoxication is suspected or needs to be excluded.

    To evaluate the reliability of radioimmunoassay for measuring serum neurosteroid dehydroepiandrosterone (DHEA) and to investigate the changes of serum DHEA level in depressive patients after treatment, the serum levels of DHEA in 40 health controls and in 40 depressive patients before and after treatment were measured by radioimmunassay. The results showed that the serum levels of DHEA in patient group before treatment were significantly lower than that in control group (P=0.001); it increased significantly after treatment (P=0.000) and were higher than that in control group (P=0.001). The serum levels of DHEA in both male and female patients after treatment were increased significantly compared with that before treatment (P=0.000). Radioimmunassay is convenient and reliable method and easy to use for the measurement of serum DHEA. The results indicate that the lower serum DHEA level in patients may be related to depression, it can be increased after treatment with antidepressant. (authors)

    Primary dysmenorrhea effects the life-quality of women negatively. The aim of this study was to evaluate heme oxygenase-1 (HO1) activity together with malondialdehyde (MDA) and nitric oxide (NO) levels in patients with primary dysmenorrhea. A total of 28 nulliparous women with the diagnosis of primary dysmenorrhea and 26 healthy controls were included in this study. On the first day of menstruation, all patients underwent ultrasound examination to exclude pelvic pathology and the visual analogue scale was applied to patients. Patient's visual analogue scale (VAS) scores, age, body mass index (BMI), menstrual cycle length (day), length of bleeding (day) were recorded. In the same day, fasting blood samples were taken from each patient for biochemical analysis. Serum MDA, NO and HO1 levels were found to be higher in women with primary dysmenorrhea compared to healthy controls (p = 0.012, p = 0.009, p dysmenorrhea. Antioxidant support might be helpful to reduce pain severity in primary dysmenorrhea.

    The association between serum uric acid (SUA) and mortality has been conflicting among studies using hemodialysis (HD) patients. Given the close link between purine and protein in foods, we hypothesized that normalized protein catabolic rate (nPCR), a dietary protein intake surrogate, modifies the SUA-mortality association in the HD population. We identified 4298 patients who initiated HD and had one or more SUA measurement in a contemporary cohort of HD patients over 5 years (1 January 2007-31 December 2011), and examined survival probability according to the first uric acid measurement, adjusting for dialysis vintage, case-mix and malnutrition-inflammation complex-related variables. Mean SUA concentration was 6.6 ± 1.8 mg/dL. There was a consistent association of higher SUA with better nutritional status and lower all-cause mortality irrespective of adjusted models (Ptrend 6.0-7.0 mg/dL) showed no significant mortality risk [hazard ratio (HR) 0.90, 95% confidence interval (CI) 0.72-1.13], while the lowest category (HD patients. Contrary to the general population, low but not high SUA is associated with higher all-cause mortality in HD patients, especially in those with low protein intake. Nutritional features of SUA warrant additional studies. © The Author 2017. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

    Autologous serum eye drops are considered safe and efficient for the treatment of various ocular surface disorders, including dry eye diseases (DED) caused by the primary and secondary Sjogren syndrome (SS). However, the serum components in patients of SS may be different from those of normal patients and can thus lead to unpredictable therapeutic effects. This study divided the SS patients into active and inactive types based on the erythrocyte sedimentation rate and the presence or absence of active rheumatoid arthritis. We compared the serum components of these two groups with standard and multiplex enzyme linked immunosorbent assay arrays and predicted the therapeutic effects of topical autologous serum for the treatment of DED with ocular surface disease index (OSDI) and Oxford Schema scale (OSS). Hyaluronic acid and transforming growth factor b1 levels were significantly higher in the active SS group compared to the inactive SS group ( P Sjogren dry eye patients into active and inactive groups may appear as a reasonable method to predict the quality of autologous serum eye drops, but there seems to be no significant predictability to the therapeutic effects.

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

    We studies a relationship between the serum levels of thrombomodulin(TM) and the thyroid functions. Serum TM levels were measured in 48 patients with Graves' disease, 17 patients with primary hypothyroidism, 7 patients with subacute thyroiditis, 5 patients with painless thyroiditis and 2 patients with systematic Refetoff syndrome. These patients did not have malignant tumor, kidney failure, or blood vessel injury. Control sera were obtained from 42 healthy subjects. Serum levels of TM in patients with untreated Graves' disease were significantly higher(p thyroid function(FT3, FT4 and TH) in patients with Graves' disease during treatment showed that both the serum levels of TM and thyroid hormones (FT3 and FT4) lowered progressively during treatment. After normalization of serum FT3 and FT4, the serum TM levels returned to normal. However, the serum levels of TM in patients with destructive thyroiditis and Refetoff syndrome were normal in spite of high serum levels of thyroid hormones. These data suggest that an increase in serum levels of TM is not the direct result of thyroid hormones themselves but is the result of the prolonged hypermetabolic state induced by their peripheral activities. Thyroid hormones may stimulate the synthesis or metabolism of TM on the surface of vascular endothelial cells in the patients with Graves' disease.

    The role played by the microenvironment in cancer induction, promotion and progression is crucial. Emerging evidence suggests that cytokines, chemokines and growth factors are major players in carcinogenesis. Therefore, a detailed understanding of factors and mechanisms associated with the processes leading from inflammation to cancer could improve the therapeutic strategies against this disease. We have used hepatocarcinoma as our model in this study. We evaluated the serum levels of 50 different cytokines, chemokines and growth factors in patients affected by HCC with chronic HCV-related hepatitis and liver cirrhosis using multiplex biometric ELISA-based immunoassay. Our data showed that some pro-inflammatory molecules were significantly up-regulated in these patients, and highlighted the complexity of the cytokine network in this disease. This work suggests the need to monitor these proteins in order to define a profile that could characterize patients with HCC or to help identify useful markers. This could lead to better definition of the disease state, and to an increased understanding of the relationships between chronic inflammation and cancer.

Thirty-one patients with CD were enrolled in this study. All patients were placed on an enteral nutrition regimen with Elental(R) (Ajinomoto pharmaceutical. Ltd., Tokyo, Japan). Serum selenium, zinc and copper concentrations were determined by atomic absorption spectroscopy. Serum selenoprotein P levels were determined by an ELISA system. Average serum levels of albumin, selenium, zinc and copper were 4.1 +/- 0.4 g/dl, 11.2 +/- 2.8 microg/dl, 71.0 +/- 14.8 microg/dl, and 112.0 +/- 25.6 microg/dl, respectively. In 9 patients of 31 CD patients, serum albumin levels were lower than the lower limit of the normal range. Serum selenium, zinc and copper levels were lower than lower limits in 12 patients, 9 patients and 1 patient, respectively. Serum selenium levels significantly correlated with both serum selenoprotein P levels and glutathione peroxidase activity. Supplementation of selenium (100 microg/day) and zinc (10 mg/day) for 2 months significantly improved the trace element status in CD patients. In conclusion, serum selenium and zinc levels are lower in many CD patients on long-term enteral nutrition. In these patients, supplementation of selenium and zinc was effective in improving the trace element status.

    To evaluate the significance of assay of serum thyroglobulin(Tg) in monitoring the course of the thyroid cancer or its response to treatment, serum thyroglobulin levels were measured in 41 patients with thyroid cancer who visited Seoul National University Hospital from August, 1981 to August, 1982. The results were as follows: 1) Serum Tg levels 1-3 months after thyroidectomy was 31±23 ng/ml(mean±S.D.) in 14 patients without metastasis, 66±41 ng/ml in 21 patients with regional metastasis and 176±59 ng/ml in 6 patients with distant metastasis and there were significant differences among three groups(p 131 I treatment were 134±62 ng/ml and 67±52 ng/ml respectively. 3) In the follow-up measurement of serum Tg levels every 3 months for about 1 year, almost all serum Tg levels were below 60 ng/ml in 12 patients without distant metastasis and serum Tg levels were elevated above 60 ng/ml in 5 of 6 patients with distant metastasis. 4) In 6 patients with distant metastasis, serum Tg levels were elevated in 5 patients and 131 I Whole body scan showed definite metastatic evidence in 3 patients and suspicious evidence in 1 patient. From above results, we concluded that serum Tg level is very useful as an indicator of recurrence or metastasis in patients with thyroid cancer after operation.

    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.)

    Background Literature supports the “response-to-retention” hypothesis—that during insulin resistance, impaired metabolism of remnant lipoproteins can contribute to accelerated cardiovascular disease progression. We used the JCR:LA-cp rat model of metabolic syndrome (MetS) to determine the extent of arterial accumulation of intestinal-derived remnants ex vivo and potential mechanisms that contribute to exacerbated cholesterol deposition in insulin resistance. Methods and Results Arteries from control and MetS (insulin-resistant) JCR:LA-cp rats were perfused ex vivo with Cy5-labeled remnant lipoproteins, and their arterial retention was quantified by confocal microscopy. Arterial proteoglycans were isolated from control and MetS rats at 6, 12, and 32 weeks of age. There was a significant increase in the arterial retention of remnants and in associated cholesterol accumulation in MetS rats as compared to control rats. Mechanistic studies reveal that increased cholesterol deposition is a result of greater arterial biglycan content; longer glycosaminoglycans and increased production of cholesterol-rich intestinal-derived remnants, as compared to controls. Additionally, perfusion of vessels treated with ezetimibe, alone or in combination with simvastatin, with remnants isolated from the respective treatment group reduced ex vivo arterial retention of remnant-derived cholesterol ex vivo as compared to untreated controls. Conclusions Increased progression of atherosclerotic cardiovascular disease in MetS and type 2 diabetes mellitus might be explained in part by an increase in the arterial retention of cholesterol-rich remnants. Furthermore, ezetimibe alone or in combination treatment with simvastatin could be beneficial in ameliorating atherosclerotic cardiovascular disease in insulin resistance and MetS. PMID:23316299

    Full Text Available Deficiencies in essential trace elements are associated with impaired immunity in tuberculosis infection. However, the trace element concentrations in the serum of Korean patients with tuberculosis have not yet been investigated. This study aimed to compare the serum trace element concentrations of Korean adult patients with tuberculosis with noninfected controls and to assess the impact of serum trace element concentration on clinical outcome after antituberculosis treatment. The serum concentrations of four trace elements in 141 consecutively recruited patients with tuberculosis and 79 controls were analyzed by inductively coupled plasma-mass spectrometry. Demographic characteristics were also analyzed. Serum cobalt and copper concentrations were significantly higher in patients with tuberculosis compared with controls, while zinc and selenium concentrations were significantly lower (p < 0.01. Moreover, serum selenium and zinc concentrations were positively correlated (ρ = 0.41, p < 0.05. A high serum copper concentration was associated with a worse clinical outcome, as assessed after one month of antituberculosis therapy. Specifically, culture-positive patients had higher serum copper concentrations than culture-negative patients (p < 0.05. Patients with tuberculosis had altered serum trace element concentrations. Further research is needed to elucidate the roles of individual trace elements and to determine their clinical impact on patients with tuberculosis.

    Full Text Available Despite recent studies showing that serum Cystatin C(CysC is a better marker for glomerular filtration rate (GFR than the ubiquitously used creatinine, the clinical utility of this remains to be evaluated. This marker is very sensitive for alograft function after renal transplantation. Concentration of CysC was compared with that of creatinine. Decreased renal function was followed in 64 transplanted patients. Plasma CysC significantly correlated (r=0.625, p<0.001 with creatinine in healthy controls. In these patients the mean plasma creatinine and Cystatin C concentrations were: 81+/-13 mmol/L,0.90 +/-0.22 mg/L, respectively. Plasma Cystatin C and creatinine significantly correlated throughout the post-transplantation period (r=0.686, p<0.001, but we confirmed differences between kinetics of these parameters. In the first four days after transplantation the CysC concentration was normalized faster than creatinine concentration. Development of acute rejection episode ( between 5 and 7 days showed high sensitivity and specificity of the changes of CysC compared with those of creatinine

    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

    Cytokines are polypeptides that have a wide spectrum of inflammatory, metabolic, hematopoietic and immunologic regulatory properties. The liver represents an important site of synthesis and clearance organ for several cytokines. This study aimed to evaluate serum IL-6 in liver cirrhosis with the type of underlying disease, child pugh group and various clinical and laboratory parameter. This cross-sectional study was at Adam Malik General Hospital and Pirngadi General Hospital from July - December 2016. We examine 75 patients with liver cirrhosis. The exclusion criteria were hepatoma, sepsis and renal impairment. There were 28 (37.3%), 8 (10.6%) and 39 (52%) for HBV-positive; HCV-positive and HBV- HCV negative liver cirrhosis patients, respectively were 14 (18.7 %), 15 (20 %) and 46 (61.3%) for Child- Pugh A, B and C respectively. There was no significant difference value of IL-6 between HBV positive, HCV positive, and HBV-HCV negative group (7.7/6.1/10.9). There was no significant difference value of IL-6 between child pugh A, B, and C group (4.2/11.0/7.9).

    Objective: To investigate the relationship between serum thyroid hormones levels and severity of heart failure in patients with coronary heart disease (CHD). Methods: Serum thyroid hormones (FT 3 , FT 4 , TSH) levels were measured with RIA in 38 patients with CHD but no cardiac failure, 40 CHD patients with heat failure and 37 controls. Results: The serum FT 3 levels in patients with heart failure were significantly lower than those in the other two groups (P 4 and TSH in all these three groups of subjects. Moreover, the serum FT 3 levels in the patients with heart fail- ure were significantly positively correlated with the ejection fractions (EF) in these patients. Conclusion: Serum FT 3 levels dropped markedly in CHD patients with heart failure and the magnitude of decrease was positively correlated with the severity of the disease. (authors)

    Objective: To study the effect of maluoning treatment on serum NPY contents in patients with COPD. Methods: To COPD patients were divided into two groups: treatment group (n=40), control groups (n=30). Serum NPY contents were determined in two groups patients at 1d-3d before admission and one year later respectively. Results: The serum NPY level in two groups of COPD patients were not much different at admission(89.4±15.2) pg/ml vs (90.5±15.6) pg/ml (P>0.05). Serum NPY contents in 40 patients with Maluoning treatment after one year were apparently lower than those in the 30 patients without Maluoning treatment (72.9±13.8) pg/ml vs (81.8±14.6) pg/ml (P<0.05). Conclusion: Maluoning could markedly reduce the serum NPY content in patients with COPD. (authors)

    In order to evaluate the clinical significances of the serum vitamin B 12 , 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 B 12 , 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 B 12 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 B 12 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 B 12 and ferritin may be useful as tumor markers in patients with malignant tumors.

    Objective: Females with different menopausal status are compared for serum lipids to explore the role of menopausal status in developing gallstones. Methodology: This study was conducted at Institute of Biochemistry, University of Sindh Jamshoro, Pakistan. A total number of 135 female gallstone patients admitted at Liaquat University Hospital, Wali Bhai Rajputana Hospital, Hyderabad and other hospitals of Hyderabad, Pakistan and 170 age and gender matched control subjects were selected for the study. The serum samples of patients of different menopausal status and control group were analyzed for the lipid contents. Gallstones recovered from the patients were also analyzed for the composition by FTIR. Results: Serum total cholesterol (TC) and serum high density lipoprotein cholesterol (HDL-C) were significantly varied among all age groups while serum triglycerides (TG), serum very low density lipoprotein cholesterol (VLDL-C) and serum total lipids (TL) were found to be significantly differed among four different types of gallstone formers. Consumers of non-branded oil and non-branded ghee were found with significant lipid alterations in comparison to control group. Major lipid alterations were found in female gallstone patients with pre and peri-menopause. Conclusion: Raised serum TC, serum TG and decreased serum HDL-C in addition to pre- and peri-menopausal status may be considered as biomarkers for female gallstone patients.

    Conclusion: Serum resistin levels are elevated in patients with acute STEMI. This increase is more evident in patients with T2DM than those without T2DM, denoting higher degrees of inflammation. However, serum resistin is not correlated with age, gender, BMI, and insulin resistance. These data denote that serum resistin concentration might be used as a diagnostic biomarker for acute STEMI. In addition, optimization of the treatment of T2DM could improve cardioprotection.

    Full Text Available Abstract Objetive Thrombospondin-1 serum levels is correlate with pelvic pain in patients with ovarian endometriosis. Patients Thrombospondin-1 serum levels were prospectively analysed in 51 patients (group A asymptomatic patients or patients presenting mild dysmenorrhea and women comprised group B severe dysmenorrhea and/or chronic pelvic pain and/or dyspareunia who underwent surgery for cystic ovarian endometriosis to asses whether a correlation exists among thrombospondin-1 serum levels and pelvic pain. Results From 56 patients, five cases were ultimateley excluded, because the histological diagnosis was other than cystic ovarian endometriosis (2 teratomas and 3 haemorragic cysts. The mean thrombospondin-1 serum levels in group A was 256,69 pg/ml_+37,07 and in group B was 291,41 pg/ml + 35,59. Conclusion Pain symptoms in ovarian endometriosis is not correlated with thrombospondin-1 serum levels.

    2003-01-01

    To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P 0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

    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.

    We aim to assess serum sodium and potassium levels in patients with different types of cerebro-vascular accidents (CVA) in comparison to control group. A comparative cross-sectional study conducted on patients admitted to the emergency department from January to August 2012. Control group consisted of patients admitted to emergency department due to common cold, urinary tract infection, low back pain, cluster, and tension headache or migraine. Serum sodium and potassium levels were measured via standard laboratory methods. There were 77 patients in control group and 78 in CVA group. Forty nine patients from the CVA group had ischemic CVA, 11 had hemorrhagic CVA and 18 suffered a transient ischemic attack (TIA). Serum sodium level in control group was significantly lower than in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Serum potassium level in control group was higher than patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Patients with hemorrhagic CVA showed significantly lower serum potassium level than patients with TIA and ischemic CVA (P < 0.001). Correspondingly, it was observed that serum sodium to potassium ratio was higher in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). In patients with hemorrhagic CVA serum sodium to potassium ratio was higher when compared to patients with TIA and ischemic CVA (P < 0.001). This study shows that higher serum sodium and lower serum potassium level may be associated with higher incidence of CVA. Further studies are paramount to elucidate the role of serum electrolyte levels in vascular events.

    Objective: To investigate the clinical significance of changes of serum pepsinogen and gastrin levels in patients with gastric/duodenal ulcer. Methods: Serum pepsinogen I (PG I), pepsinogen II (PGII), gastrin levels and PG I/PG II ratio were determined with RIA in 100 controls, 61 patients with duodenal ulcer, 46 patients with gastric ulcer, 66 patients with gastric cancer and 101 patients with chronic gastritis. Results: In patients with peptic ulcer (gastric/duodenal), the serum levels of PG I, PG II and PG I/PG II ratio were significantly higher than those in controls (P<0.001); the serum gastrin levels were also significantly higher than those in controls and patients with chronic gastritis (P<0.001), but lower than those in patients with gastric cancer (P<0.001). Among patients with peptic ulcer, the serum PG I level and PG I/PG II ratio were significantly higher in patients with duodenal ulcer than those in patients with gastric ulcer (P<0.001). Conclusion: Excessive high serum levels of PG I, PG II, gastrin and PG I/PG II ratio were some of the high risk factors for peptic ulcer. Those were useful serum markers for diagnosis and follow-up of the disease. (authors)

  19. Decreased serum hepcidin concentration correlates with brain iron deposition in patients with HBV-related cirrhosis.

    Directory of Open Access Journals (Sweden)

    Dong Lin

    Full Text Available PURPOSE: Excessive brain iron accumulation contributes to cognitive impairments in hepatitis B virus (HBV-related cirrhotic patients. The underlying mechanism remains unclear. Hepcidin, a liver-produced, 25-aminoacid peptide, is the major regulator of systemic iron metabolism. Abnormal hepcidin level is a key factor in some body iron accumulation or deficiency disorders, especially in those associated with liver diseases. Our study was aimed to explore the relationship between brain iron content in patients with HBV-related cirrhosis and serum hepcidin level. METHODS: Seventy HBV-related cirrhotic patients and forty age- sex-matched healthy controls were enrolled. Brain iron content was quantified by susceptibility weighted phase imaging technique. Serum hepcidin as well as serum iron, serum transferrin, ferritin, soluble transferrin receptor, total iron binding capacity, and transferrin saturation were tested in thirty cirrhotic patients and nineteen healthy controls. Pearson correlation analysis was performed to investigate correlation between brain iron concentrations and serum hepcidin, or other iron parameters. RESULTS: Cirrhotic patients had increased brain iron accumulation compared to controls in the left red nuclear, the bilateral substantia nigra, the bilateral thalamus, the right caudate, and the right putamen. Cirrhotic patients had significantly decreased serum hepcidin concentration, as well as lower serum transferring level, lower total iron binding capacity and higher transferrin saturation, compared to controls. Serum hepcidin level negatively correlated with the iron content in the right caudate, while serum ferritin level positively correlated with the iron content in the bilateral putamen in cirrhotic patients. CONCLUSIONS: Decreased serum hepcidin level correlated with excessive iron accumulation in the basal ganglia in HBV-related cirrhotic patients. Our results indicated that systemic iron overload underlined regional

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

    Serum phosphate concentrations usually show great variability in patients with advanced chronic kidney disease (ACKD) not on dialysis. Diuretics treatment can have an influence over the severity of mineral-bone metabolism alterations related to ACKD, but their effect on serum phosphate levels is less known. This study aims to determine whether diuretics are independently associated with serum phosphate levels, and to investigate the mechanisms by which diuretics may affect phosphate metabolism. 429 Caucasian patients with CKD not on dialysis were included in this cross-sectional study. In addition to conventional serum biochemical measures, the following parameters of renal phosphate excretion were assessed: 24-hours urinary phosphate excretion, tubular maximum phosphate reabsorption (TmP), and fractional excretion of phosphate (FEP). 58% of patients were on treatment with diuretics. Patients on diuretics showed significantly higher mean serum phosphate concentration (4.78 ± 1.23 vs. 4.24 ± 1.04 mg/dl; Pdiuretics. By multivariate linear and logistic regression, significant associations between diuretics and serum phosphate concentrations or hyperphosphataemia remained after adjustment for potential confounding variables. In patients with the highest phosphate load adjusted to kidney function, those treated with diuretics showed significantly lower FEP than those untreated with diuretics. Treatment with diuretics is associated with increased serum phosphate concentrations in patients with ACKD. Diuretics may indirectly interfere with the maximum renal compensatory capacity to excrete phosphate. Diuretics should be considered in the studies linking the relationship between serum phosphate concentrations and cardiovascular alterations in patients with CKD.

    Recent evidence from animal studies indicates that fibroblast growth factor 21 (FGF21), an endocrine hormone that regulates glucose, lipid metabolism, and energy homeostasis, is regulated by T3. However, the role of FGF21 in hyperthyroid patients is unknown. The objective was to study serum FGF21 levels in hyperthyroid patients and the association of serum FGF21 levels with hyperthyroidism. This was a case-control study. A total of 119 hyperthyroid patients and 108 healthy subjects were recruited. Of them, 41 hyperthyroid patients received thionamide treatment for 3 months until euthyroidism was obtained. Serum FGF21 levels were determined using the ELISA method. Serum FGF21 levels were significantly elevated in hyperthyroid patients as compared with normal subjects [median 290.67 (interquartile range, 156.60-502.33) vs 228.10 (169.85.25-320.10) pg/mL; P treatment, serum FGF21 levels in hyperthyroid patients declined markedly from 249.10 (139.10-444.00) to 106.90 (38.70-196.15) pg/mL (P hyperthyroidism. With adjustment for potential confounders, serum FGF21 remained independently associated with hyperthyroidism, with an adjusted odds ratio of 3.123 (95% confidence interval, 1.306-7.468) (P = .010). Serum FGF21 levels were elevated in patients with hyperthyroidism and declined after thionamide treatment. And serum FGF21 level was independently associated with hyperthyroidism.

    Matrix metalloproteinase 11 (MMP11) has been shown to play a key role in human tumor progression and indicates poor clinical outcome in cancer patients. The current study aimed to evaluate the relationship between serum levels of MMP-11 and prognosis in colon cancer patients. Serum levels of MMP-11 were determined in 92 colon cancer patients and 92 healthy individuals using an enzyme-linked immunosorbent assay (ELISA). Associations between serum MMP-11 levels and clinicopathological characteristics of the patients and their outcomes were investigated. Survival analyses were performed to measure the 5-year overall survival (OS) and disease-free survival (DFS). Serum MMP-11 levels were substantially higher in colon cancer patients than in healthy controls. Moreover, serum MMP-11 levels were significantly higher in patients with advanced T status, lymph node metastasis, distant metastasis, and a higher TNM stage. Elevated serum levels of MMP-11 were identified as an independent prognostic factor for 5-year mortality and adverse events associated with colon cancer. Multivariate Cox regression analysis identified the serum MMP-11 level as an independent predictor of OS and DFS. Our study established that high serum levels of MMP-11 are associated with poor clinical outcome and may serve as a prognostic biomarker in colon cancer patients.

    Having noted an increased serum level of TPA and CEA in patients with renal carcinoma the authors extended these studies by using a larger number of tumor markers. In 15 patients (11 men and 4 women after menopause) aged 33 to 74 years who had renal carcinoma, among them 3 with tumor metastases, the serum concentration of TPA, CA 12-5, CEA, AFP, ferritin, prolactin, β-HCG, and β/sub 2/-microglobulin was measured by radioimmunoassay. Monoclonal antibodies were used in the determination of serum CA 12-5 and CEA. In all patients surgical treatment, irradiation, or cytostatic therapy had not been performed. In serum the normal range was exceeded by TPA in 7 patients, CA 12-5 in 3, CEA and AFP in one each, ferritin in 12, prolactin in 2, and β/sub 2/-microglobulin in 10 patients. In one man serum prolactin was reduced. Serum β-HCG was normal in all patients. According to these results serum ferritin, TPA, and β/sub 2/-microglobulin are of great value as tumor markers in patients with renal carcinoma. In several patients the increase of serum β/sub 2/-microglobulin may be ascribed partly to deterioration of renal function. As no consistent patterns of tumor markers in serum were observed it is recommended to determine several tumor markers and not only one of them during the follow-up of patients. Radioimmunoassays for measuring the serum level of tumor markers, especially ferritin, TPA, and β/sub 2/-microglobulin, may considerably assist in the management of patients with renal carcinoma by providing early information about tumor recurrence or metastases

    Full Text Available Contrast-induced nephropathy (CIN is the third leading cause of acute kidney injury in hospitalized patients. The prevalence of CIN is reported to range from 0% to 50%, depending not only on patient condition and the procedure used but also the definition of CIN applied. We aimed to determine the best diagnostic indicator of CIN in patients with normal serum creatinine. This study included 206 patients with normal serum creatinine who underwent coronary angiography/angioplasty. Serum creatinine level and glomerular filtration rate (GFR were measured before and on the second and fifth days after contrast administration. The incidence of CIN based on a 25% increase in serum creatinine was calculated and compared with the incidence based on a 25% decrease in GFR or an increase of at least 0.5 mg/dL in serum creatinine. Of 206 patients, 127 were male (61.7% and 79 were female (38.3%; the mean age was 59.56 ± 10.3 years. The prevalence of CIN was 30% based on a 25% increase in serum creatinine, 23% based on a 25% decrease in GFR (P <0.012 and 3.8% based on a serum creatinine increase of at least 0.5 mg/dL (P <0.0001. The serum creatinine levels remained within the normal range in the majority of patients with CIN based on the different definitions. In patients with normal serum creatinine, the absolute increase in serum creatinine may describe the prevalence of CIN more accurately than the relative increase in serum creatinine or relative decrease in GFR.

    Objective: To investigate the relationship between the serum level of endostatin and the clinical pathophysiological characteristics in patients with primary lung cancer. Methods: The serum levels of endostatin were detected in 48 patients with primary lung cancer and 50 patients with benign pulmonary diseases by enzyme-linked immunosorbent assay (ELISA) method. Results: Serum endostatin level in patients with primary lung cancer was significantly higher than it in patients with benign pulmonary diseases (P<0.01). It was higher in adenocarcinoma group than that in squamous cell carcinoma and small cell carcinoma group (P<0.05). The level of serum endostatin in lung cancer with TNM stage III + IV was higher than that in patients in stage I + II (P<0.01). And it was also higher in patients suffering from lung cancer with metastasis than that in patients with no metastasis (P<0.05). However, there was not a significant relation between serum endostatin level the location of the tumor and lymph node metastasis. Conclusion: Serum endostatin level in expressed higher in patients with primary lung cancer. There is significant relationship between serum endostatin level, histological classification, TNM stage and metastasis of lung cancer. (authors)

    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

    Shu-ichi Fujita

    Full Text Available BACKGROUND: Several studies have shown that serum uric acid (UA is associated with left ventricular (LV hypertrophy. Serum levels of parathyroid hormone (PTH, which has bbe shown to be correlated with UA, is also known to be associated with cardiac hypertrophy; however, whether the association between UA and cardiac hypertrophy is independent of PTH remains unknown. PURPOSE: We investigated whether the relationship between serum uric acid (UA and LV hypertrophy is independent of intact PTH and other calcium-phosphate metabolism-related factors in cardiac patients. METHODS AND RESULTS: In a retrospective study, the association between UA and left ventricular mass index was assessed among 116 male cardiac patients (mean age 65 ± 12 years who were not taking UA lowering drugs. The median UA value was 5.9 mg/dL. Neither age nor body mass index differed significantly among the UA quartile groups. Patients with higher UA levels were more likely to be taking loop diuretics. UA showed a significant correlation with intact PTH (R = 0.34, P<0.001 but not with other calcium-phosphate metabolism-related factors. Linear regression analysis showed that log-transformed UA showed a significant association with left ventricular mass index, and this relationship was found to be significant exclusively in patients who were not taking loop and/or thiazide diuretics. Multivariate logistic regression analysis showed that log-transformed UA was independently associated with LV hypertrophy with an odds ratio of 2.79 (95% confidence interval 1.48-5.28, P = 0.002 per one standard deviation increase. CONCLUSIONS: Among cardiac patients, serum UA was associated with LV hypertrophy, and this relationship was, at least in part, independent of intact PTH levels, which showed a significant correlation with UA in the same population.

    Recently, the colon has been recognized as an important source of various uremic toxins in patients with end stage renal disease. Medicinal charcoal tablets are an oral adsorbent that are widely used in patients with chronic kidney disease in China to remove creatinine and urea from the colon. A parallel fecal and serum metabolomics study was performed to determine comprehensive metabolic profiles of patients receiving hemodialysis (HD). The effects of medicinal charcoal tablets on the fecal and serum metabolomes of HD patients were also investigated. Ultra-performance liquid chromatography/mass spectrometry was used to investigate the fecal and serum metabolic profiles of 20 healthy controls and 31 HD patients before and after taking medicinal charcoal tablets for 3 months. There were distinct metabolic variations between the HD patients and healthy controls both in the feces and serum according to multivariate data analysis. Metabolic disturbances of alanine, aspartate and glutamate metabolism, arginine and proline metabolism figured prominently in the serum. However, in the feces, alterations of tryptophan metabolism, lysine degradation and beta-alanine metabolism were pronounced, and the levels of several amino acids (leucine, phenylalanine, lysine, histidine, methionine, tyrosine, and tryptophan) were increased dramatically. Nineteen fecal metabolites and 21 serum metabolites were also identified as biomarkers that contributed to the metabolic differences. Additionally, medicinal charcoal treatment generally enabled the serum and fecal metabolomes of the HD patients to draw close to those of the control subjects, especially the serum metabolic profile. Parallel fecal and serum metabolomics uncovered the systematic metabolic variations of HD patients, especially disturbances in amino acid metabolism in the colon. Medicinal charcoal tablets had an impact on the serum and fecal metabolomes of HD patients, but their exact effects still need to be studied further

    Full Text Available This study was performed to determine the correlation between serum magnesium (Mg and dyslipidemia in patients on maintenance hemodialysis (MHD. This hospital-based cross-sectional observational study was conducted at the Department of Nephro-Urology, Liaquat University Hospital, Hyderabad, Pakistan, from April 2008 to June 2008. Fifty patients with end-stage kidney disease on MHD treatment (33 males and 17 females were studied. The mean duration on HD was 7.58 ± 2.05 years, with frequency being two to three sessions/week, and each session lasted for four hours. After obtaining informed written consent, the general information of each patient was recorded on a proforma. After overnight fasting, blood samples was drawn from the arterio-venous fistula for lipid profile, lipoprotein, serum Mg, serum creatinine, blood urea, serum calcium and serum phosphorus. Dyslipidemia was defined as presence of total cholesterol (TC, triglyceride (TG or low-density lipoprotein (LDL levels more then 95 th percentile for age and gender or high-density lipoprotein (HDL levels less then 35 mg/dL. Descriptive and inferential statistical analyses were performed using SPSS version 16.0. The mean age of the study patients was 45.68 ± 13.97 years. There was a significant positive correlation between serum Mg and serum lipoprotein-a (LP-a (r = 0.40, P < 0.007, serum HDL (r = 0.31, P < 0.01 and serum TG (r = 0.35, P < 0.005. There was no significant correlation between serum Mg and serum LDL-c and serum TC. The serum TG and LP-a levels were significantly increased while HDL-c was significantly lower in MHD patients. The serum TC, LDL-c and very low-density lipoprotein-c were not significantly elevated. We conclude that patients with chronic kidney disease undergoing MHD show positive correlation between serum Mg and serum HDL, LP-a and TG. The abnormalities of lipid metabolism, such as hyper-triglyceridemia, elevated LP-a and low HDL-c, could contribute to

    To investigate serum uric acid concentration in patients with type 2 diabetes mellitus. This is a case control study conducted in Al-Wafa Diabetic Center in Mosul over a period of one year starting from January 1, 2005 to January 1, 2006. Serum glucose concentration and uric acid concentration were measured in both control and patient's groups (group 1 patients on diet therapy, group 2 patients on glibenclamide therapy and group 3 involve naturopathic patients). Serum glucose concentration was high in the diabetic groups as compared with the control group (P 0.2) except in group-3 (P<0.05). A negative correlation was reported between hyperglycemia and uric acid concentration of the different groups. Serum uric acid concentration is slightly reduced in type 2 diabetic patients particularly in the complicated patients with peripheral neuropathy and this may be due to the oxidative stress that decreases the antioxidant capacity of the body involving uric acid.

    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

    Serum lipoprotein(a) [Lp(a)] concentration was determined in 42 patients with primary nephrotic syndrome (NS) and the relationships between Lp (a) and plasma lipids, apolipoproteins, serum creatinine (Scr), albumin, urinary proteins (Upro) were also analyzed. The results showed that: (1) serum Lp(a) concentrations in the patients with NS were higher than those in healthy controls; (2) the levels of serum Lp(a) were correlated positively with total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), apolipoprotein B (Apo-B), Upros (Upro). It is concluded that the NS patients had the potential risk of suffering from coronary artery disease, glomerular sclerosis and thrombosis. The remission of NS may partially decrease the serum Lp(a) levels. Further studies are needed to explore the prevention and treatment of dislipedemia in patients with NS.

    To explore the relationship between the levels of serum adiponectin and urinary albumin excretion rate in patients with type 2 diabetes nephropathy, the serum levels of adiponectin and the levels of urinary albumin excretion rate in diabetes patients before and after treatment with pioglitazone were tested by ELISA and automatic biochemical analyzer respectively. The results showed that the serum levels of adiponectin in DM and DN group were lower than that of normal controls(P<0.01), but they gradually increased with progression (P<0.01). The serum adiponectin level was positively correlated with urinary albumin excretion rate (r= 0.284, P<0.05). The urinary albumin level decreased (P<0.01) and the serum levels of adiponectin increased after treatment with pioglitazone in DN group. The serum levels of adiponectin and urinary albumin excretion rate may play important role in the indication of treatment of diabetes. (authors)

    Serum TSH was measured by means of double antibody radioimmunoassay using a commercial Kit Daiichi, in 21 normal subjects, 200 patients with thyroid disease and 130 patients with hypothalamic-pituitary diseases. Serum TSH concentrations in normal subjects were <2 to 8 μU/ml which rose to 8-40 μU/ml after administration of 500 μg TRH intravenously. Serum TSH was undetectable and did not respond to TRH in all untreated patients and in some euthyroid patients with Graves' disease after treatment. Undetectable TSH and no response to TRH were also observed in most patients with a hyperfunctioning thyroid nodule and those with subacute thyroiditis in the acute phase. In some patients with Hashimoto's thyroiditis and all patients with adult myxedema and cretinism, serum TSH levels were increased and showed hyperresponse to TRH. The ratio of bioassay and radioimmunoassay potency estimates for TSH in sera obtained before TRH was not statistically different from that obtained after TRH administration to patients with primary hypothyroidism. Elevated serum TSH was promptly decreased by the administration of thyroid hormone to the patients. More than 50% of patients with pituitary adenoma, acromegaly and craniopharyngioma showed normal basal TSH and no or low response of TSH to TRH. Administration of TRH failed to stimulate a rise in serum TSH in 2 sisters with isolated TSH deficiency with cretinism. Basal TSH was undetectable and showed delayed response to TRH in patients with anorexia nervosa. (auth.)

    Full Text Available Purpose: We investigated the correlations of serum total testosterone (TT levels with body composition and physical fitness parameters in patients with erectile dysfunction (ED to know the best exercise for testosterone deficiency. Materials and Methods: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly correlated with serum TT levels. Results: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation with serum TT levels. Conclusions: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory fitness via aerobic exercise.

    To study the clinical significance of determination of serum B7-H4 in patients with malignant hematologic diseases. Serum B7-H4 levels were determined in 65 patients with leucemia, 34 patients with lymphoma, 12 patients with multiple myeloma as well as in 50 healthy controls. The serum B7-H4 levels in patients with lymphoma [(38.81+/-10.34) kappag/L] were significantly higher than healthy controls [(31.62+/-9.850) kappag/L] (Pleucemia, patients with multiple myeloma and healthy controls. These results suggest that the B7-H4 may correlated with lymphoma, but uncorrelated with leucemia and multiple myeloma. Measurement of serum B7-H4 level provide useful information for distinctive diagnosis of different kinds of malignant hematologic diseases.

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P 0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

    Objective. To examine alteration of serum interleukin-6 and its clinical significance in burning mouth syndrome (BMS) patients. Methods. 48 BMS patients and 31 healthy controls participated in the study. Serum interleukin-6 was measured by means of ELISA. Hamilton rating scale of depression (HRSD) and visual analogue scale (VAS) were used to quantitiate depressive status and pain levels of subjects, respectively. Results. 15 (31%) patients displayed substantial depressive symptoms (HRSD ≧ 16). HRSD scores of patients were significantly higher than controls and positively correlated to their VAS values (P = .002). Serum interleukin-6 in patients was much lower than controls and negatively correlated to their VAS values (P = .011). However, no significant relations were found between interleukin-6 and HRSD scores (P = .317). Conclusions. Serum interleukin-6 in patients with burning mouth syndrome is decreased and negatively correlated to chronic pain. Both psychological and neuropathic disorders might act as precipitating factors in BMS etiopathogenesis. PMID:17641729

    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

    Since serum can reflect human beings' physiological and pathological conditions, FTIR spectroscopy was used to compare gastric cancer patients' serum with healthy persons' serum in this study. The H2959/H2931, H1646/H1550, H1314/H1243, H1453/H1400 and H1080/H1550 ratios were calculated, among these ratios, the H2959/H2931 ratio might be a standard for distinguishing gastric cancer patients from healthy persons. Then curve fitting was processed using Gaussian curves in the 1140-1000 cm-1 region, and the result showed that the RNA/DNA ratios of gastric cancer patients' serum were obviously lower than those of healthy persons' serum. The results suggest that FTIR spectroscopy may be a potentially useful tool for diagnosis of gastric cancer.

    Cancer antigen 125 (CA-125) is a glycoprotein biomarker that is used in women with pelvic masses such as endometriosis and maybe is useful in practice of patients suspicious to endometriosis. The aim of this study was to evaluate the association between preoperative serum CA-125 levels and clinic pathological characteristic in women with endometriosis, and find out the best serum CA-125 levels cut-off in pre and post menopause women. Serum CA-125 levels in 87 women aged 21-54 years suspected to endometriosis with pelvic pain, dysmenorrhea, or dyspareunia were measured preoperatively. Also the association between clinic pathological characteristic and serum CA-125 level were analyzed. The mean age of women was 32.22±6.91. The mean serum CA-125 level was 49.93±4.30 U/mL. There was a significant correlation between the endometriosis stage, lesion size, adhesion score and preoperative CA-125 plasma concentration. However, we did not found significant differences in age, marital status, patient's complaints, and pelvic pain associated to Ca125 serum level. The suggested preoperative serum cut-off levels in premenopausal and postmenopausal patients were 37 U/ml and 35 U/ml, respectively. According to the results, preoperative serum CA-125 is an important predictor for patients with endometriosis and it should be taken into consideration when surgical management is suspected, especially if stage of disease, lesion size and adhesion score are undertaken.

  17. Serum microRNA-122 predicts survival in patients with liver cirrhosis.

    Directory of Open Access Journals (Sweden)

    Oliver Waidmann

    Full Text Available BACKGROUND: Liver cirrhosis is associated with high morbidity and mortality. MicroRNAs (miRs circulating in the blood are an emerging new class of biomarkers. In particular, the serum level of the liver-specific miR-122 might be a clinically useful new parameter in patients with acute or chronic liver disease. AIM: Here we investigated if the serum level of miR-122 might be a prognostic parameter in patients with liver cirrhosis. METHODS: 107 patients with liver cirrhosis in the test cohort and 143 patients in the validation cohort were prospectively enrolled into the present study. RNA was extracted from the sera obtained at the time of study enrollment and the level of miR-122 was assessed. Serum miR-122 levels were assessed by quantitative reverse-transcription PCR (RT-PCR and were compared to overall survival time and to different complications of liver cirrhosis. RESULTS: Serum miR-122 levels were reduced in patients with hepatic decompensation in comparison to patients with compensated liver disease. Patients with ascites, spontaneous bacterial peritonitis and hepatorenal syndrome had significantly lower miR-122 levels than patients without these complications. Multivariate Cox regression analysis revealed that the miR-122 serum levels were associated with survival independently from the MELD score, sex and age. CONCLUSIONS: Serum miR-122 is a new independent marker for prediction of survival of patients with liver cirrhosis.

    Background. Metabolic acidosis, usually manifested by low serum bicarbonate level, is common in chronic kidney disease (CKD) and appears to be associated with higher mortality in dialysis patients. It is not known whether a similar association is present in patients with non-dialysis-dependent CKD (NDD-CKD). Methods. We used multivariable-adjusted Cox models to examine the association between baseline and time-variable serum bicarbonate (measured as total CO2) with the outcomes of all-cause mortality and the composite of pre-dialysis mortality or end-stage renal disease in 1240 male patients with moderate and advanced NDD-CKD. Results. Serum bicarbonate showed a significant U-shaped association with all-cause mortality, with the highest mortality rate observed in patients with baseline serum bicarbonate levels <22 mmol/L [multivariable-adjusted hazard ratio (95% confidence interval) for patients with serum bicarbonate <22 mmol/L versus ≥22 mmol/L: 1.33 (1.05–1.69), P = 0.02] and the lowest mortality observed in patients with baseline serum bicarbonate of 26–29 mmol/L. The associations between lower serum bicarbonate level and mortality were more accentuated in subgroups of patients with better nutritional status and lower inflammation. Conclusions. Both lower and higher serum bicarbonates are associated with increased all-cause mortality in patients with moderate and advanced NDD-CKD. Clinical trials are needed to determine if therapeutic interventions aimed at optimizing serum bicarbonate can result in improved outcomes in this population. PMID:19015169

    Objective: To investigate the relationship between serum adiponectin concentration and diabetic nephropathy in patients with type 2 diabetes mellitus. Methods: The serum adiponectin concentrations were measured with RIA in 163 patients with type 2 diabetes mellitus and 50 controls. Results: In the diabetic patients, serum adiponectin concentrations were significantly higher in patients with macro albuminuria (n = 54) than those inpatients with microalbuminuria (n = 57) (P 0.05). Adiponectin concentrations were higher in women than in men, but there was no significant difference (P > 0.05). Conclusion: Serum adiponectin concentrations are increased in type 2 diabetic patients with advanced nephropathy. The kidney seems to be involved in the metabolism and excretion of adiponectin. Adiponectin may play important roles in the onset and development of diabetic nephropathy. (authors)

    There is no surrogate marker in serum for defining disease activity in scleroderma (SSc). Nitric oxide (NO), which regulates vasodilation and possesses pro-inflammatory actions, has been implicated in the pathogenesis of SSc. We compared serum NO(x) (total nitrate and nitrite) level in SSc patients to healthy controls and evaluated its correlation with detailed symptomatology and scoring systems for various organ involvement. Symptoms and physical findings that suggested disease activity in regard to various organs were documented. Lung function test, high-resolution computed tomographic (HRCT) scan of thorax and echocardiography were performed. Serum NO(x) was measured by chemiluminescence. Serum NO(x) levels in SSc (n = 43) were significantly higher (72.4 +/- 47.8 microM) than age- and sex-matched controls (n = 41; 37.1 +/- 13.5 microM; p n = 9; OR 145.3, p = 0.01) were predictive factors for elevated serum NO(x). Prednisolone use was associated with lower serum NO(x) level (OR 0.06, p = 0.04). Elevated PAP of increasing severity was found to be associated with higher level of serum NO(x) (p = 0.004 by trend). Serum NO(x) in SSc patients were elevated compared to healthy controls. Serum NO(x) level was determined by multiple factors including age, prednisolone use, and elevated PAP.

    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.

    Summary Background: We aimed to compare ghrelin, obestatin, homocysteine (Hcy), vitamin B12 and folate levels in the serum and saliva of ischaemic heart disease patients. Methods: Serum and saliva were collected from 33 ischaemic heart disease (IHD) patients and 28 age- and body mass index-matched healthy individuals. Levels of acylated and desacylated ghrelin, obestatin and Hcy were determined using the ELISA method. Results: Acylated ghrelin, desacylated ghrelin and obestatin levels in the saliva were found to be higher than those in the serum of the control group, while acylated and desacylated ghrelin levels in the saliva were significantly lower than those in the serum. Obestatin levels were higher in IHD patients (p = 0.001). Saliva and serum vitamin B12 and folate levels in IHD patients were significantly lower than in the control group (p = 0.001). Conclusions: It was determined that serum ghrelin levels increased in ischaemic heart disease patients, while serum levels of obestatin decreased. PMID:28759087

    The main objective of the study was to evaluate the endocrinological picture of anorexia. Serum leptin levels are low in untreated anorexia nervosa (AN), but studies of the exact relationship between leptin, body weight and hormones of hypothalamo-hypophyseal-thyroid axis and the impact of refeeding in anorectics are limited. The sample consistent of 15 patients with anorexia nervosa before and 1 month after partial weight recovery, and 15 age-matched control subjects. The body mass index (BMI), leptin, plasma neuropeptide Y (NPY), serotonin, thyroxine (T4), triiodothyronine (T3) and reverse triiodothyronine (rT3) in serum were evaluated for each subject. The mean serum levels of leptin, T4, and T3 were significantly lower before weight recovery in 15 patients with AN than they were in control subjects. After partial weight recovery, basal T3 levels were unchanged and significantly lower than in controls. Basal T4 was even still more reduced, but we observed significantly elevated ratio of T3/T4 and reduced ratio rT3/T4 of in AN patients after gain recovery, indicating increased conversion of T4 to T3 than to rT3. The levels of serum leptin were low in AN, but after partial weight recovery slightly increased, and correlated with BMI. No differences were observed in serum NPY. Serum levels of IGF-1 and serotonin were lower in AN than in controls before and after partial weight gain. IGF-1 was slightly increased after partial weight gain. We did not find correlation between serum levels of leptin and serum T4. The low serum levels of T3 associated with chronic starvation were thought to be the result of impaired peripheral conversion of T4 to T3. However, decreased levels of T3 were still apparent even after a partial weight gain, and the concentration of T4 was even lower. The diminished serum level of TSH in AN, however, appeared to return to the level of controls. On the basis of these results, we assume that low serum levels of thyroid hormones in AN reflect a

    Objective To detect serum HER-2 oncoprotein levels in patients with operable and metastatic breast cancers, and to study the correlations between serum HER-2 level and lymph node status as well as other clinical parameters.Methods A total of 120 women were studied consisting of 10 healthy volunteers, 31 benign breast disease, 53 operable breast cancer, and 26 metastatic breast cancer patients. The levels of serum HER-2 were measured using an enzyme-liked immunosorbent assay (ELISA).Results The mean serum HER-2 levels were 9.6 + 1.5 ng/mL in healthy volunteers, 11.9 + 1.6 ng/mL in benign breast disease, 13.2 + 4.2 ng/mL in operable breast cancer, and 30.5 + 30.8 ng/mL in metastatic breast cancer patients. The former is much lower than the latter three (P=0.02, 0.001, 0.03, respectively). If using 15 ng/mL as a normal baseline, elevated serum HER-2 levels were observed in none of the healthy volunteers as well as patients with benign disease, but in 18.9% (10/53)operable breast cancer patients and 61.5% (16/26) metastatic patients. In patients with operable breast cancer, there was a positive correlation between serum concentrations of HER-2 and the size of primary rumor (P < 0.05), whereas there was no correlation between serum concentration and axillary lymph node or estrogen receptor status. In patients with metastatic disease, there was no correlation with site of metastases (P > 0.05).Conclusion Serum HER-2 level was strongly correlated with rumor loads and clinical stages, thus acting as a promising predictor of cancer recurrence in breast cancer patients.

    A third of the population are estimated to have NAFLD of varying severity. Serum immunoglobulins are frequently elevated in patients with chronic liver disease, but little is known about serum immunoglobulin levels in patients with NAFLD. Aim of this study was to evaluate serum immunoglobulin levels (IgA, IgG, and IgM) in a large cohort of patients with biopsy-proven NAFLD and determine if immunoglobulin levels are associated with clinical or histological features. Patients seen in a tertiary fatty liver clinic between 1999 and 2009 were included. Liver biopsies were assessed using the Kleiner score. Immunoglobulin levels and other blood tests were taken at time of biopsy. 285 patients (110 simple steatosis and 175 NASH) had serum immunoglobulins measured within 6months of liver biopsy. 130 (46%) patients had elevated (>1× upper limit of normal) serum IgA levels, 28 (10%) patients had elevated IgG and 22 (8%) raised IgM. Serum IgA levels were elevated more frequently in patients with NASH compared with subjects with simple steatosis (55% vs. 31%, pliver fibrosis (Kleiner stage 3-4). There was a significant positive association between serum IgA levels and the stage of fibrosis (pfibrosis following multivariate analysis. A model constructed from these independent predictors accurately predicted advanced fibrosis (AUROC 0.87). The serum IgA level was frequently elevated in patients with NAFLD and was an independent predictor of advanced fibrosis. Copyright © 2014 European Association for the Study of the Liver.

    Increased levels of C-reactive protein (CRP) have been considered as a marker in assessing neurogenic inflammation of migraine patients. An inverse relationship between serum bilirubin and CRP has been observed in various diseases. Therefore, we analyzed serum bilirubin levels in migraine patients, and investigated the relationship between serum bilirubin and CRP in migraineurs. A total of 86 newly diagnosed migraine patients were consecutively recruited to this study. Significantly lower median serum total bilirubin, conjugated bilirubin (CB) and unconjugated bilirubin were found in patients with migraine than healthy controls, and the levels of CRP were significantly higher in migraine patients than healthy controls. A negative correlation between CRP and CB was observed in patients with migraine (r = -0.255, P = 0.018). In a multiple linear regression model, the concentrations of CRP remained negatively correlated with CB. Our study demonstrates that serum bilirubin concentrations are decreased in migraineurs, and CB levels were found to be positively correlated with CRP in migraine patents. However, larger cross-sectional and prospective studies are needed to establish whether serum bilirubin may be a useful biomarker for assessing neurogenic inflammation in migraine patients and eventually guiding the therapy. © 2016 Wiley Periodicals, Inc.

    The purpose of this study was to measure the salivary and serum free IGF-1 concentration of patients with anorexia nervosa (AN) in comparison to an average population. A controlled clinical trial was designed for an age- and gender-matched group of 121 AN patients and 77 healthy individuals. A clinical examination was made and blood and salivary samples were taken during the acute stage of AN (BMI measuring free IGF-1 was used. Anorexic patients had significant reductions in salivary unstimulated flow rate (UFR), pH and free IGF-1 levels in their saliva and serum. Significant correlations between serum IGF-1 and BMI; salivary IGF-1 and UFR and pH were detected. Salivary and serum IGF-1 analyses appear to be a reliable biochemical indicator of malnutrition in AN patients. Measurement of salivary IGF-1 levels would allow new perspectives in monitoring AN in its early stages.

    Full Text Available Serum cholinesterase levels are closely correlated with the severity of liver disease. The aim of the paper was to assess the value of serum cholinesterase in evaluating liver reserve function in cirrhotic patients. 90 patients with liver cirrhosis and thirty healthy control group were included. Liver cirrhosis patients were classified according to child score into three equal groups: Child A liver cirrhosis, Child B liver cirrhosis and Child C liver cirrhosis. Patients were subjected to clinical evaluation, laboratory analysis, abdominal U/S. Measuring serum cholinesterase, and Calculation of both Child and model of end stage liver disease (MELD scores. The level of serum cholinesterase was higher in control group than the three groups of liver cirrhosis with median (IQR 17,410 (12,111-21,774, 7528 (5200-9856, 6021 (4500-7542, 3828.5 (1541-6060, respectively P<0.001. And the level of serum cholinesterase was higher in Child A more than Child B and Child C and the level of serum cholinesterase was higher in Child B more than Child C with very strong negative correlation between serum Cholinesterase level and Child score (r=-0.9, P<0.001. Also strong negative correlation between serum Cholinesterase level and MELD score (r=- 0.85, P=0.001, and positive correlation with prothrombin concentration (r=0.554, P=0.009, and serum albumin levels (r=0.582, P=0.0002. Serum cholinesterase is a good biomarker of cirrhosis. Since it distinguishes decompensated from compensated cirrhosis well, low levels in cirrhosis may serve as a useful prognostic marker of advanced liver disease.

    Chromogranin A is an important tool in the diagnosis of neuroendocrine tumors. Autoimmune gastritis is an autoimmune disorder marked by hypergastrinemia, which stimulates enterochromaffin-like cell proliferation. Chromogranin A is also elevated in autoimmune gastritis patients with a different level of increase in each patient. The goal of this study is to explore constituents that influence serum chromogranin A levels in autoimmune gastritis patients. One hundred and eighty-eight autoimmune gastritis patients and 20 patients with type I gastric carcinoid tumors were analyzed retrospectively and compared to 110 functional dyspepsia patients in terms of factors that might affect serum chromogranin A levels. The mean serum chromogranin A level was 171.17±67.3 ng/mL in autoimmune gastritis patients (n=62) without enterochromaffin-like cell hyperplasia, and 303.3±102.82 ng/mL in patients (n=126) with enterochromaffin-like cell hyperplasia (pgastritis were the presence of ECL cell hyperplasia and serum gastrin levels. Serum chromogranin A levels maybe helpful in distinguishing autoimmune gastritis patients and gastric carcinoid type I from the control group, but not useful in the differentiation of individuals with autoimmune gastritis from patients with gastric carcinoids.

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

    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 T 3 and free T 4 (FT 3 and FT 4 ) 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 FT 3 , FT 4 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.

    Depression is associated with low serum Brain Derived Neurotrophic Factor (BDNF) and elevated levels of serum cortisol. Yoga practices have been associated with antidepressant effects, increase in serum BDNF, and reduction in serum cortisol. This study examined the association between serum BDNF and cortisol levels in drug-naïve patients with depression treated with antidepressants, yoga therapy, and both. Fifty-four drug-naïve consenting adult outpatients with Major Depression (32 males) received antidepressants only (n = 16), yoga therapy only (n = 19), or yoga with antidepressants (n = 19). Serum BDNF andcortisol levels were obtained before and after 3 months using a sandwich ELISA method. One-way ANOVA, Chi-square test, and Pearson's correlation tests were used for analysis. The groups were comparable at baseline on most parameters. Significant improvement in depression scores and serum BDNF levels, and reduction in serum cortisol in the yoga groups, have been described in previous reports. A significant negative correlation was observed between change in BDNF (pre-post) and cortisol (pre-post) levels in the yoga-only group (r = -0.59, p = 0.008). In conclusion, yoga may facilitate neuroplasticity through stress reduction in depressed patients. Further studies are needed to confirm the findings and delineate the pathways for these effects.

    To determine levels of serum interferon beta (IFNbeta) neutralizing antibody (NAb) and neopterin-an IFN biologic response marker-in patients with MS treated with Betaseron or Avonex. Controversy exists over the relative immunogenicity of IFNbeta-1a and IFNbeta-1b and the reasons for any such difference. To determine the role of patient profile and test methodology in IFNbeta, NAb levels need to be measured blindly and simultaneously in a predefined closely matched MS patient cohort. Serum NAb and neopterin levels were measured in closely matched patients on Avonex (n = 98) or Betaseron (n = 64). NAb were determined by Athena Diagnostics and serum neopterin levels by Covance Laboratories using a competitive binding radioimmunoassay. More patients taking Betaseron (22%) than Avonex (7%) had elevated titers of NAb (p = 0.008). Mean serum neopterin levels were lower in patients with high as compared to low NAb titers (p = 0.0002). No difference in mean neopterin levels was found comparing the total Betaseron group to the Avonex group; however, in the subset of patients with low NAb titers, mean neopterin levels were higher in the Betaseron than in the Avonex group (p = 0.027). A random cross-sectional sampling of patients on Avonex showed a decrease in neopterin levels over time between weekly doses. NAb are more commonly found with Betaseron than Avonex. More studies are needed to determine the correlation among serum neopterin levels, other biologic response markers, NAb, and disease activity in patients with MS being treated with IFNbeta.

    Full Text Available Context: Increased quantities of glycoconjugates such as Total Sialic Acid (TSA and Lipid-bound Sialic Acid (LSA have been detected in the plasma and serum of patients with various malignancies, indicating their usefulness in diagnosis or monitoring of the treatment modality. Aims: (1 To estimate and compare the serum TSA and LSA levels in Oral Squamous Cell Carcinoma (OSCC patients before and after radiotherapy, as also in healthy individuals. (2 To determine the correlation, if any, between Tumor-Node-Metastasis (TNM staging and levels of TSA and LSA. (3 To determine the use of serum TSA and LSA as biomarkers of OSCC. Settings and Design: The study was designed as a case-control study and was undertaken in a dental college and cancer hospital. Materials and Methods: It was planned to estimate the serum TSA and LSA levels of 20 healthy individuals and of 20 OSCC patients, spectrophotometrically; before starting and one month after completion of radiotherapy. Statistical Analysis: The Statistical Package for Social Sciences (SPSS Version 10.0 was used. Results: The mean serum TSA and LSA levels in OSCC patients decreased significantly after radiotherapy; however, they were still higher than the levels in the controls. In untreated OSCC patients, a statistically significant positive correlation was observed between the TNM stage of the disease and the serum TSA levels; but the same was not found between the TNM stage of the disease and the serum LSA levels. In OSCC, the serum TSA and LSA levels had a positive relationship with the TNM stages. These levels decreased significantly after radiotherapy. Conclusion: Serum TSA and LSA can be utilized as potential diagnostic and prognostic indicators in OSCC.

    To consider the correlation of serum parathromone on severity of hypertension in end stage renal disease (ESRD) patients on hemodialysis (HD). A cross-sectional study was done on patients with ESRD on treatment with maintenance HD. Levels of serum calcium, phosphorous, alkaline phosphatase, albumin and intact parathormone (iPTH) were measured. Stratification of hypertensive patients was done from stage one to three. The total number of patients studied was 73 (Females=28, Males=45), consisting of 58 non-diabetic (F=22, M=36) and 15 diabetic patients (F=6, M=9). The mean age of the study patients was 46.5+-16 years. The mean duration on HD of the study patients was 21.5+-232.5 months. The mean serum PTH of the study patients was 309+-349 pg/ml and the mean serum alkaline phosphatase was 413+-348 IU/L. There was a significant positive correlation between the stage of hypertension and serum PTH levels (r=0.200, p=0.045). Also, there was a significant positive correlation between stage of hypertension and calcium-phosphorus product (r=0.231, p=0.027). There was no significant correlation between stage of hypertension and serum ALP (r=0.135, p=0.128). Relationship between serum PTH and severity of hypertension in patients on HD needs to be studied in more detail. Hypertension and secondary hyperparathyroidism interact in the process of accelerated atherosclerosis in HD patients thus warranting appropriate measures to control hyperparathyrodism vigorously.

    To measure the expression levels of sputum and serum microRNA-144 (miR-144) before and after the treatment of patients with tuberculosis (TB). Details of the cases of a total of 124 TB patients were collected at Qilu Hospital of Shandong University between April 2014 and April 2015. Fifty-three of these patients had sputum positive for bacteria and a cavity on imaging (group A), 20 patients had sputum negative for bacteria and a cavity on imaging (group B), and 51 patients had sputum negative for bacteria and no cavity on imaging (group C). One hundred seventeen healthy people who attended the hospital for a physical examination were recruited as controls. Quantitative real-time PCR (qRT-PCR) was used to measure the levels of sputum and serum miR-144 before anti-TB treatment and at 1 month after treatment. Before treatment, sputum and serum miR-144 expression levels in the TB patients were both higher than those of the controls (both p<0.05). After treatment, sputum and serum miR-144 levels in the TB patients were significantly lower than those measured before treatment (both p<0.05). The levels of sputum and serum miR-144 in the improved TB patients decreased significantly after treatment compared to those measured before treatment (both p<0.001). Significant differences were found in sputum and serum miR-144 levels in the TB patients, with or without improvement, compared with the healthy controls (all p<0.05). Sputum and serum miR-144 levels were significantly upregulated in the TB patients, but were found to decrease significantly after anti-TB treatment. Copyright © 2016 The Authors.

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

    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.   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.   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.   Low levels of serum cortisol and DHEA-S were suggested to be associated with the physiopathology of FMS.

    Full Text Available Objectives. Serum cystatin C seems to be an accurate marker of glomerular filtration rate (GFR compared to serum creatinine. The aim of this work was to explore the possibility of using serum cystatin C instead of serum creatinine to early predict renal failure in cancer patients who received platinum based chemotherapy. Design and Methods. Serum creatinine, serum cystatin C concentrations, and GFR were determined simultaneously in 52 cancer patients received carboplatin-based or cisplatin-based chemotherapy. Serum creatinine was assayed on Cobas C6000-Roche, serum cystatin C assay was performed on AIA 360-Tosoh, and GFR was determined in all patients, before the first cycle of chemotherapy and before the subsequent administrations. Results. In the overall series, for the prediction of a fall of GFR < 80 mL/min/1.73 m2, the AUC of the ROC curve for cystatin C was 0,667 and the best threshold was 1.135 mg/L (sensitivity 90.5%, specificity 61.1%. For a GFR fall < 60 mL/min/1.73 m2, the AUC of ROC curve for cystatin C was 74.3% and the best threshold was 1.415 mg/L (sensitivity 66.7%, specificity 73.2%. Conclusions. Baseline cystatin C values were not able to predict renal failure during subsequent treatment. In conclusion, serum cystatin C is not a reliable early marker to efficiently predict renal failure in patients receiving chemotherapy.

    Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years) attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a) a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r : 0.74; P value: 0.0001); (b) a weak association between the number of blood transfusions and serum iron concentrations (Spearman r : 0.32; P value: 0.04); (c) a weak association between serum ferritin and serum iron (Spearman r : 0.32; P value: 0.003). Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (κ = 0.14). The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1) patients with a maximum of one transfusion not on iron therapy; (2) patients with a maximum of one transfusion on iron therapy; (3) polytransfused patients not on iron therapy; and (4) polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001). Conclusion. Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC. PMID:25685597

    Hepcidin has emerged as a peptide with a key role in the regulation of iron homeostasis in patients with chronic kidney disease (CKD), having a strong dependence on inflammation. Recent studies reveal that hepcidin may be also associated with the progression of atherosclerosis. This study was performed to analyze the relation of hepcidin to markers of atherosclerosis and inflammation in patients on dialysis. A total of 90 individuals were enrolled. Sixty patients with end-stage renal disease, who were on hemodialysis (HD) (N = 30) and peritoneal dialysis (N = 30) were compared with 30 normal controls (NC). Age, body mass index, time on dialysis, serum lipids, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured and analyzed in correlation with hepcidin concentration. It was found that patients on HD and peritoneal dialysis have significantly higher (P triglycerides (r = 0.401, P = 0.005), HDL-C (r = -0.268, P = 0.048), CRP (r = 0.436, P = 0.0007) and IL-6 (r = 0.569, P triglycerides (β = 0.402, P = 0.041) and IL-6 (β = 0.559, P = 0.006). Moreover, patients with high triglycerides in combination with high IL-6 levels have significantly increased concentrations of hepcidin than those with low triglycerides and low IL-6 levels (P triglycerides and high IL-6 serum concentrations. This probably suggests that hepcidin may play a role to the progression of atherosclerosis and inflammation, but this hypothesis should be further evaluated. © 2013 The Authors.

    Full Text Available Background/Aim. The main characteristic of matrix metalloproteinases (MMPs is the degradation of extracellular matrix. Synthesis of MMPs has been reported in coronary atherosclerotic lesions in patients with coronary disease (CD suggesting a pathogenic role of MMPs in its development. Recently there is increasing evidence that gelatinase A (pro MMP-2 and gelatinase B (proMMP-9 play a pathogenic role in the development of the atherosclerotic plaques. The aim of the study was to determine, by the use of a gel image system, a possible presence of active gelatinases in the serum of the patients with CD, as well as if their activity is higher in these patients than in healthy people. Methods. By gelatin zymography we analyzed the activity of proMMP-2 and proMMP-9 in the serum of 50 patients with various coronary artery disease stages and in the serum of 15 healthy controls. The activity was measured by using a gel image system (Kodak Image 1D 3.6.. Results. ProMMP-2 and proMMP-9 activity was significantly higher in the serum of patients with CD compared to controls. There was higher activity of MMP-2 and MMP-9 in the serum of patients with acute myocardial infarction (AMI compared to patients with stable angina pectoris, as well as higher proMMP-9 activity in patients with unstable angina pectoris compared to patients with stable angina pectoris. Conclusion. ProMMP-2 and proMMP-9 participate in processes associated with destabilizing plaques and understanding the processes of MMPs activation and regulation may have significant benefits in clinical interpretation. The reported higher proMMP-2 and proMMP-9 activity in the serum of patients with CD suggests a role of proMMP-2 and proMMP-9 in prognostic stratification of these patients and in designing new drugs.

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

    We investigated the relationship between serum bilirubin and disease activity in patients with rheumatoid arthritis (RA). We included a total of 173 consecutive RA patients without steroid treatment and 346 healthy subjects; the disease activity score in 28 joints (DAS28) was used to assess disease activity in patients with RA. Serum bilirubin concentrations were significantly lower in RA patients than in controls. Serum bilirubin was found to be negatively correlated with C-reactive protein (CRP) concentration and erythrocyte sedimentation rate (ESR) (r=-0.165, P=0.030; r=-192, P=0.012) in patients with RA. There was a negative correlation between the serum bilirubin and DAS28 score (r=-0.331, Pbilirubin was independently associated with the DAS28 score (b=-0.225, P=0.001) in the multiple linear regression analysis. Serum bilirubin concentrations are lower in patients with RA compared to controls and correlate with disease activity in patients with RA. Copyright © 2017. Published by Elsevier B.V.

    One of the most specific and critical regulators of angiogenesis is vascular endothelial growth factor (VEGF), which regulates endothelial proliferation, permeability, and survival. Vascular endothelial growth factor is an angiogenic mediator in tumors and has been implicated in the pathogenesis and progression of cancer. Adipose tissue is a major endocrine and it secretes hormones termed adipokines. These factors are derived from adipocytes and include proteins and metabolites such as adiponectin. Recently, adiponectin was also shown to modulate angiogenesis. This study was designed to determine the serum VEGF and adiponectin levels in patients with benign and malignant gynecological diseases and if there was a correlation between serum VEGF and adiponectin. Serum samples, collected fasting before surgery or intervention, were available for total of 114 female patients recorded between October 2006 and December 2008. Diagnosis of benign and malignant gynaecological diseases was established by biopsy. Serum levels VEGF and adiponectin were using commercially available enzyme linked immunosorbent assay (R&D Systems Inc, Minneapolis, MN), respectively. Statistical analysis was performed by using the SPSS 9.0 software package (SPSS, Inc, Chicago, IL). The correlation between serum VEGF and serum Adiponectin was calculated using the Pearson correlation coefficient. P values of benign and malignant gynecological diseases of the patient. Only for serum VEGF levels was a significant difference observed (P = 0.004) between patients with benign and malignant gynecological diseases. A significantly inverse correlation between serum VEGF and adiponectin levels among patients with benign and malignant gynecological diseases was found. Adiponectin level is not correlated with body mass index. This is one of the first report on adiponectin in benign and malignant gynecological diseases. Future studies are needed to address the clinical potential role of adiponectin in cancer.

    Caspase-3 is the main executor of the apoptotic process. Higher serum caspase-3 concentrations in non-survivor compared to survivor septic patients have been found. The objectives of this work (with the increase of sample size to 308 patients, and the determination of serum caspase-3 concentrations also on days 4 and 8 of diagnosis of severe sepsis) were to know whether an association between serum caspase-3 concentrationss during the first week, degree of apoptosis, sepsis severity, and sepsis mortality exists. We collected serum samples of 308 patients with severe sepsis from eight intensive care units on days 1, 4 and 8 to measure concentrations of caspase-3 and caspase-cleaved cytokeratin (CCCK)-18 (to assess degree of apoptosis). End point was 30-day mortality. We found higher serum concentrations of caspase-3 and CCCK-18 in non-survivors compared to survivors on days 1 (p < 0.001), 4 (p < 0.001), and 8 (p < 0.001). We found an association between serum caspase-3 concentrations on days 1, 4 and 8 of severe sepsis diagnosis and serum CCCK-18 concentrations (p < 0.001), SOFA (p < 0.001), serum acid lactic concentrations (p < 0.001), and 30-day sepsis mortality (p < 0.001). The new findings of this work were that an association between serum caspase-3 concentrations during the first week, apoptosis degree, sepsis severity, and sepsis mortality exists.

    Fetuin-A is a glycoprotein secreted by liver and has been shown to inhibit extraosseous mineralization. Urolithiasis may be a manifestation in the urinary tract due to fetuin deficiency in urine. The objective of this study was to compare the 24-h urine and serum fetuin-A levels of patients with and without urolithiasis. Serum and 24-h urine fetuin-A levels were measured in 41 patients with bilateral, multiple, or recurrent urinary tract calculi (Group A) and 41 matched controls with no calculi (Group B). Fetuin levels were measured by enzyme linked immunosorbent assay. Serum and urine fetuin-A levels in the two groups were compared. The median (range) 24-h urine fetuin-A value in Group A was 11.9 (1.12-221) mg/day and in Group B was 37.7 (1.28-125) mg/day. This difference was statistically significant (Mann-Whitney test, P = 0.0169). The median (range) serum fetuin-A in Group A was 0.67 (0.05-2.68) g/L and in Group B was 0.99 (0.01-5.5) g/L. The difference between serum values in the two arms was not statistically significant (Mann-Whitney test, P = 0.1817). However, the serum creatinine-adjusted mean log serum fetuin and urine fetuin were significantly different in the two arms ( P = 0.003). The mean ± standard deviation (range) serum creatinine in Group A was 0.98 ± 0.25 (0.56-1.58) mg% and in Group B was 0.83 ± 0.16 (0.58-1.18) mg% (two sample t -test, P = 0.0031). Patients with urolithiasis have lower urine fetuin-A and creatinine-adjusted serum fetuin-A levels.

    Full Text Available Preterm labour and prematurity are still a main cause of perinatal morbidity nowadays. The aim of our study was to assess the role of MMP-8 as a predictive marker of preterm delivery. Four groups of patients were involved to the study: I - pregnant women at 24-34 weeks of gestation with any symptoms of threatened preterm labour; II - threatened preterm labour patients between 24-34 weeks of gestation; III - preterm vaginal delivery patients; IV - healthy term vaginal delivery patients. Serum concentration of total MMP-8 was measured using two enzyme-linked immunosorbent assays. There were no significant differences in the median concentrations of total MMP-8 between physiological pregnancy and threatened preterm labour patients with existing uterine contractility. No significant differences of total MMP-8 were either found between healthy term and preterm labouring patients. The studies on a larger population are needed to reject the hypothesis that preterm labour is connected with increased MMP-8 plasma concentrations of women in preterm labour and threatened preterm delivery.

    Differentiate bacterial infections from flare in SLE patients is difficult to do because clinical symptoms of infection is similar to flare. SLE patients with infection require antibiotic therapy with decreased doses of immunosuppressant while in flare diseases require increased immunosuppressant. Procalcitonin (PCT), a biological marker, increased in serum patients with bacterial infections and expected to be a solution of problem. The aim of this study was to examine the function of PCT serum as marker to differentiate bacterial infection and flare in SLE patients. This cross-sectional study was conducted in Adam Malik Hospital from January-July 2017. We examined 80 patients SLE flare (MEX-SLEDAI>5), screen PCT and culture according to focal infection. Data were statistically analyzed. 80 SLE patients divided into 2 groups: bacterial infection group (31 patients) and non-infection/flare group (49 patients). Median PCT levels of bacterial infection group was 1.66 (0.04-8.45)ng/ml while flare group was 0.12 (0.02-0.81)ng/ml. There was significant difference of serum Procalcitonin level between bacterial infection and flare group in SLE patients (p=0.001). Procalcitonin serum levels can be used as a biomarker to differentiate bacterial infections and flare in SLE patients.

    Testosterone may have a role distinct from cortisol in the pathophysiology of depression. The hypothalamus-pituitary-adrenal (HPA) axis affects the functions of sex steroid hormones through interaction with corticotropin-releasing hormone (CRH) and gonadotropin-releasing hormone (GnRH). The objective of this study was to investigate differences in serum levels of testosterone and cortisol in male and female patients with major depressive disorder (MDD). Participants included 87 inpatients with MDD at Juntendo University Koshigaya Hospital. Serum levels of testosterone and cortisol were assessed at admission. Matched controls included 128 healthy individuals. Data from MDD patients and controls were compared separately for men and women. Correlations between serum hormone levels and scores on the Hamilton Rating Scale for Depression (HAM-D) of patients were assessed by sex. Effects of various factors on testosterone and cortisol were analyzed using multiple regression analysis. In male patients with MDD, a significant negative correlation was seen between testosterone levels and the "retardation" score of HAM-D. However, serum testosterone levels were not significantly different in either male or female MDD patients compared with controls. Serum testosterone was negatively associated with the number of depressive episodes in male patients with MDD. Serum cortisol levels in female patients were significantly increased compared with female controls with no significant correlations between cortisol levels and HAM-D scores. The negative correlation between the sub-score of the HAM-D and testosterone may be associated with the biological pathophysiology of male depression. Findings of serum cortisol levels in women may suggest distinct characteristics of these hormones in men and women with MDD.

    To evaluate blood and serum markers in traumatic spinal cord injured (SCI) patients, with and without pressure sores. This cross-sectional study was performed at the Ministry of Health Diskapi Yildirim Beyazit, and Numune Education and Research Hospitals, Ankara, Turkey, from 2006-2008. A total of 23 SCI patients with pressure sores (group I) and a control group of 25 SCI patients without pressure sores (group II) were evaluated. Characteristics of sores were examined with respect to duration, location, grade, tissue types, surface area, and exudate amount. Recorded laboratory parameters included erythrocyte sedimentation rates (ESR), C-reactive protein (CRP), hemoglobin (Hb), hematocrit (Htc), lymphocytes, white blood cells (WBC), red blood cells (RBC), serum iron, transferrin, total iron-binding capacity (TIBC), ferritin, total protein, albumin, vitamin B12, and zinc. The most common pressure sore location was the sacrum (38%). Compared to the control group, the patients with pressure sores showed anemia with reduced serum iron, transferrin, TIBC, and increased ferritin. They also had increased ESR, CRP, and WBC and reduced lymphocytes, total protein, albumin and zinc. Statistically significant correlations were found between CRP, Hb, Htc, lymphocytes, RBC, WBC, and serum protein levels, and grade of pressure sores. Clinicians should regularly screen patients with respect to blood and serum markers, in order to determine any risks for pressure sores, and they should perform immediate preventive measures based on the patient's condition.

    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

    Objective: To investigate the relationships between changes of serum sex hormones levels and protein-lipid metabolism in patients with ulcerative colitis. Methods: Serum levels of estradiol (E 2 ) pregnenedione (P), prolactin(PRL), luteinizing hormone (LH), follicle-stimulating hormone (FSH) (with CLIA), sree testos (T, with RIA) and total-protein (TP), albumin (Alb), globulin (G), albumin/globulinratio (A/G) total-cholesterd (TC), high density lipoprotein cholesterols (LDL-C) (with biochemistry were determined in 72 patients) with ulcerative colitis and 72 controls. Results: The serum levels of T, LH, FSH, TP, Alb, A/G, TC, LDL-C in patients with ulcerative colitis were significantly lower than those in controls (P 2 , PRL in patients with ulcerative colitis were significantly higher than those in controls (P 2 were negatively correlated with TP, A/G and TC (P 2 levels in the female sex (P>0.05) as well as between LH, FSH and T levels in the male sex (P>0.05). Conclusion: The abnormal serum levels of sex hormone might contribute to the development of hypoproteinaemia and lowered lipid levels in patients with ulcerative colitis. Treatment with correction of serum sex hormones levels might be beneficial to the patients. (authors)

    Circulating levels of melatonin in patients with traumatic brain injury (TBI) have been determined in a little number of studies with small sample size (highest sample size of 37 patients) and only were reported the comparison of serum melatonin levels between TBI patients and healthy controls. As to we know, the possible association between circulating levels of melatonin levels and mortality of patients with TBI have not been explored; thus, the objective of our current study was to determine whether this association actually exists. This multicenter study included 118 severe TBI (Glasgow Coma Scale melatonin, malondialdehyde (to assess lipid peroxidation) and total antioxidant capacity (TAC) at day 1 of severe TBI. We used mortality at 30 days as endpoint. We found that non-survivor (n = 33) compared to survivor (n = 85) TBI patients showed higher circulating levels of melatonin (p melatonin levels predicted 30-day mortality (Odds ratio = 1.334; 95% confidence interval = 1.094-1.627; p = 0.004), after to control for GCS, CT findings and age. We found a correlation between serum levels of melatonin levels and serum levels of TAC (rho = 0.37; p melatonin levels in patients with severe TBI. The main findings were that non-survivors had higher serum melatonin levels than survivors, and the association between serum levels of melatonin levels and mortality, peroxidation state and antioxidant state.

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

    Objective: To investigate the clinical significance of thymosin α1(Tα1) measurement in evaluating clinical status of patients with solid malignant tumors. Methods: Tα1 levels in serum of 50 normal adults, 20 patients with benign tumors and 63 patients with malignant tumors were measured by enzyme linked immunosorbent assay (ELISA). The association of Tα1 level with tumor invasion, metastasis and its alteration after different treatment in patients with malignant tumors were also studied. Results: The serum Tα1 level was 0.69±0.35 μg/L in normal adults, 0.96±0.37 μg/L in patients with benign tumors and 1.46±0.90 μg/L in patients with malignant tumors. In comparison it was both increased between patients with benign and malignant tumors and the normal adults (P<0.01 and P<0.001). And its increasing extent in malignant tumors was much greater than that in benign tumors (P<0.05). The serum Tα1 level in patients with malignant tumors was correlated with tumor invasion, metastasis and different treatment intervention. Conclusions: Our findings suggest that the serum Tα1 level be increased in tumor patients, and that it may be used as a new tumor marker in clinic

    A best evidence topic was written according to a structured protocol. The question addressed was: in patients undergoing oesophagectomy for oesophageal malignancy, is low serum albumin associated with postoperative complications? Altogether, 87 papers were found using the reported search, of which 16 demonstrated the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. This paper includes 2 level 2 papers, 12 level 3 papers and 2 level 4 papers. All the papers compared either all or some of the following postoperative complications: mortality, morbidity, anastomotic leak, respiratory and non-respiratory complications, and length of hospital stay. Eleven of the 16 papers found an association between low serum albumin and postoperative complications. Of these, one study showed that low serum albumin combined with low fibrinogen levels (FA score) was predictive of postoperative recurrence of oesophageal cancer. Another study showed that when combined with white cell count and C-reactive protein (CRP, NUn score), serum albumin had a high diagnostic accuracy for major complications after postoperative day 3. The largest study compared the in-hospital mortality in 7227 patients who underwent oesophageal surgery for malignancy. The percentage of in-hospital mortality was associated with low serum albumin (35.0 g/l, 21.0 vs 11.3%, P papers found no significant association between low serum albumin and postoperative complications. Of these papers, one showed that low serum albumin was not an independent risk factor, while four others found no association between low serum albumin with respiratory complications, anastomotic leak and postoperative mortality. Instead, these studies found other factors responsible for postoperative complications such as: CRP, smoking, disease duration, malnutrition and low T-cell levels. Taken together

    The concentration of serum LN is determined by radioimmunoassay in 78 diabetic patients and 30 normal subjects as control. The mean concentration of LN in total 78 diabetic patients [(132.54 +- 31.05) μg/L] is higher than that of control [(97.63 +- 19.31) μg/L, P<0.01], especially in group B [(134.25 +- 29.12)μg/L] and group C [(158.51 +- 37.82)μg/L] are remarkably higher as comparable with control (P<0.01). There is significantly positive correlation between serum LN and diabetic duration, UAE, FBG. The results show that abnormal laminin metabolism exists in diabetic patients. The increased serum LN level in diabetic patients related to the severity of diabetic renal lesion and could be an early and sensitive marker of DN

    Full Text Available Vitamin B12 levels in the serum of 58 epileptic patients receiving only carbamazepine for at least 6 months were measured. Same number of epilepsy patients with no history of taking antiepileptic medicine were taken as control. The mean level of vitamin B12 in carbamazepine-treated epileptic patients was 265.5 pg/mL whereas it was 478.3 pg/mL in control. Increased duration of treatment of carbamazepine in epilepsy caused significantly decreased level of serum vitamin B12 (Pearson correlation coefficient, r = -0.9, p<0.0001. In conclusion, serum vitamin B12 level significantly decreased in relation to duration of carbamazepine treatment in epileptic patients.

    During the period from June. 1969 to Dec. 1970, the serum protein electrophoretic patterns of 44 cases of various cancer patients have been studied to determine the alterations in serum protein fractions in patients who were responding to irradiation or those failing. The serum electrophoretic pattern could be observed as an indicator of prognosis or radiosensitivity. A blood sample was obtained prior to any treatment and the follow up sampling was performed 2 times during radiation therapy. Serum total protein was determined by the method of Wolfson and serum electrophoresis was carried out by using Spinoco Model R B electrophoresis system. The results were following: Seven cases out of cases of cervical cancer responding favorably to radiotherapy showed decreased in Alpha-2 globulin fraction were increased. A case whose third time serum electrophoretic pattern showed multiple myeloma type died 5 months after radiotherapy with bone metastasis. Four cases out of 9 cases of favorably responded breast cancer patients showed decreased in Alpha-2 globulin foraction compared with 2 cases of unfavorable response showed increased in Alpha-2 globulin fraction

    To investigate the correlation between serum CEA and colorectal cancer, the pre-and postoperative serum CEA in 120 patients with colorectal cancer was measured by RIA, with other 24 cases of healthy donors as control. The results showed that serum CEA in control group and patient group were 9.84±2.44 ng/mL, 38, 85±19.21 ng/mL respectively, while colonic cancer group 37.43±18.58 ng/mL, rectal cancer group 39.72±20.67 ng/mL. There was significant difference between patient group and control group (P 0.05). Serum CEA of 37 among 44 cases with positive CEA findings decreased to 11.21±3.65 ng/mL during two months follow-up post-operation, whereas 50.63±24.38 ng/mL in 7/44 cases undergoing non-radical operation. The serum CEA of 41 recurrence cases was 43.12±17.15 ng/mL at six-year post-operation, with 87.80% of three-year recurrence rate. It suggested that the serum CEA test is a convenient method for colorectal cancer to preoperatively diagnose it, evaluate postoperative curative effect and detect tumor recurrence and metastasis

    Background Endocan (endothelial cell-specific molecule-1) is a proteoglycan and plays an important role in angiogenesis and inflammation. The aim of this study was to evaluate of serum and urinary concentrations of endothelial cell-specific molecule-1 in bladder cancer. Methods The study included 50 bladder cancer patients, 50 with urinary tract infection and 51 healthy volunteers. Serum and urinary endothelial cell-specific molecule-1 concentrations were measured with enzyme linked immunosorbent assay. Results In bladder cancer group, serum and urinary endothelial cell-specific molecule-1 concentrations were significantly higher than in the healthy subjects ( P = 0.003 and P bladder cancer and urinary tract infection groups in terms of serum and urinary endothelial cell-specific molecule-1 concentrations. Urinary endothelial cell-specific molecule-1 concentrations were higher than those of corresponding serum endothelial cell-specific molecule-1 concentrations ( P bladder cancer and urinary tract infection groups, P = 0.002 for healthy subjects). In bladder cancer group, there was a positive correlation between serum endothelial cell-specific molecule-1 and urinary endothelial cell-specific molecule-1 concentrations ( r = 0.32, P = 0.002). For serum endothelial cell-specific molecule-1, sensitivity and specificity were 50%, and 77%, and for urinary endothelial cell-specific molecule-1, 62%, and 71%, respectively. Conclusion Serum and urinary endothelial cell-specific molecule-1 concentrations increase in bladder cancer. This parameter also increases in serum and urine of cases with urinary tract infection. That urinary endothelial cell-specific molecule-1 values were higher than serum endothelial cell-specific molecule-1 values in all groups may be attributed to direct exfoliation of epithelial cells in bladder to urine.

    Polycystic ovary syndrome (PCOS) is a common endocrine disease that affects reproductive-aged women and mostly characterized by insulin resistance (IR). The underlying mechanism remains unknown. Long noncoding RNAs (lncRNAs) have been demonstrated to be involved in various levels of biological regulation process of cell development, metabolism, and differentiation. This study aims to investigate the relationship between IR and differential expression of lncRNA Growth-arrest specific transcript 5 (GAS5) in patients' serum with and without PCOS. A total of 76 cases of serum was collected from non-PCOS and PCOS patients with and without IR to measure interleukin-18 (IL-18) and GAS5 expression, which were correlated with IR status. The IL-18 concentration in serums was significantly increased in PCOS patients with IR. GAS5 expression was decreased in serums in PCOS patients with IR. Result of correlation analysis shows that there is a negative association between GAS5 expression and homeostasis model of assessment for insulin resistance (HOMA-IR). GAS5 was yielded the ROC curve (AUC). Our study implied that elevated IL-18 expression and downregulation of GAS5 in serums might contribute to IR in PCOS patients.

    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 This study aimed to investigate the association between serum YKL-40 and prognosis of breast cancer in a Chinese population. Expression of YKL-40 of 120 Chinese patients with breast cancer and 30 controls (benign breast lesions was measured in tumor tissue by immunohistochemistry and in serum by ELISA. Differences in YKL-40 positivity grouped by specific patients' characteristics were compared using Pearson Chi-square test for rates of intratumoral staining, one-way ANOVA with a Bonferroni post-hoc comparison, or two-sample t-test for mean YKL-40 serum concentrations. Factors associated with overall survival were identified by univariate and multivariate cox-regression analyses. YKL-40 was elevated in approximately 75% of Chinese patients with breast cancer. A significantly higher percentage of patients with YKL-40 positive tumors had larger tumor size, higher TNM stage, and/or lymph node metastasis. Significantly higher mean YKL-40 serum concentrations were observed in patient subgroups with invasive lobular carcinoma (P<0.0167, higher TNM stage (P<0.001, and positive lymph node metastasis (P<0.001. The estimated mean survival time of patients with YKL-40 positive tumors was significantly shorter than for patients with YKL-40 negative tumors (55.13 months vs 65.78 months, P = 0.017. Multivariable Cox-regression analysis identified a significant association of overall survival time with YKL-40 serum concentration. Patients with YKL-40 positive tumors had significantly shorter disease free survival times than those with YKL-40 negative tumors. We propose that the potential utility of YKL-40 intratumoral staining or serum concentration as a biomarker for breast cancer is greatest within 5 years of diagnosis.

    Full Text Available Stroke still has a high incidence with a tremendous public health burden and it is a leading cause of mortality and disability. However, biomarkers for early diagnosis are absent and the metabolic alterations associated with ischemic stroke are not clearly understood. The objectives of this case-control study are to identify serum biomarkers and explore the metabolic alterations of ischemic stroke.Metabonomic analysis was performed using ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry and multivariate statistical analysis was employed to study 60 patients with or without ischemic stroke (30 cases and 30 controls.Serum metabolic profiling identified a series of 12 metabolites with significant alterations, and the related metabolic pathways involved glycerophospholipid, sphingolipid, phospholipid, fat acid, acylcarnitine, heme, and purine metabolism. Subsequently, multiple logistic regression analyses of these metabolites showed uric acid, sphinganine and adrenoyl ethanolamide were potential biomarkers of ischemic stroke with an area under the receiver operating characteristic curve of 0.941.These findings provide insights into the early diagnosis and potential pathophysiology of ischemic stroke.

    Premature ejaculation (PE) is the most common male sexual dysfunction. This study aimed to investigate the role of serum testosterone, gonadotropins and prolactin in patients with PE. In a prospective a case-controlled study, it was conducted on 90 male patients with PE and 90 male healthy participants as controls. Patients were evaluated by Premature Ejaculation Diagnostic Tool (PEDT) and intravaginal ejaculatory latency time (IELT). Patients with mean IELT values ≤60 s and PEDT total scores ≥11 were considered to have PE. Serum levels of total testosterone (TT), free testosterone (FT), follicle-stimulating hormone (FSH), luteinising hormone (LH) and prolactin (PL) were investigated in patients with PE and controls. There was no statistically significant difference between patients with PE and controls regarding the serum levels of TT, FT, FSH, LH and PL (p value ˃.05). There was no significant correlation between the sex hormones levels (TT, FT, FSH, LH and PL) and (age, body mass index (BMI), IELTS and total PEDT scores of the patients; p value ˃.05). This study concluded that there was no disturbance in serum levels of testosterone, gonadotropins and prolactin in patients with PE and controls. These hormones could not relate to pathogenesis of PE. © 2017 Blackwell Verlag GmbH.

    To assess whether subclinical hypothyroidism is associated to elevations in serum cholesterol and triglyceride levels in patients with type 2 diabetes. From a total population of 1,112 patients with type 2 diabetes screened for thyroid dysfunction (thyrotropin measurement), a group of 325 patients with normal thyroid function and another group of 29 patients with subclinical hypothyroidism were selected. No patient had known dyslipidemia or was taking lipid lowering medication. Patients with subclinical hypothyroidism had serum levels of total cholesterol (4.88 ± 0.74 mmol/L), HDL cholesterol (1.37 ± 0.34 mmol/L), LDL cholesterol (2.94 ± 0.58 mmol/L), and triglycerides (1.05 [0.88-1.41] mmol/L) that did not significantly differ from those found in euthyroid patients (4.79 ± 0.83, 1.33 ± 0.36, 2.87 ± 0.76, and 1.11 [0.81-1.43] mmol/L, respectively). Multiple regression analysis showed no association between TSH and serum lipid levels. These results suggest that, in our population, there are no significant differences in serum cholesterol and triglyceride levels between diabetic patients with normal and reduced thyroid function.

    2012-01-01

    Background Up-regulation of lysosomal cysteine protease cathepsin X (Cat X) is associated with disorders of the immune system and neurodegenerative diseases, while its role in the development and progression of cancer is less understood. Enhanced secretion of pro-Cat X was observed in malignant processes, and therefore, the level of total serum Cat X rather than the active enzyme may better reflect the tumour status. Patients and methods Seventy-seven patients with colorectal cancer (CRC) were included in a retrospective study. Blood samples were collected prior to therapy. Using ELISA, the values of total Cat X were measured in serum. Groups of healthy persons (n=77), patients with adenomas (n=77) and patients with non-neoplastic findings (n=77) were included. Results Significant differences between the group of colorectal patients and the groups of healthy persons, adenoma patients and patients with non-malignant findings could not be shown (p=0.89). Within the group of CRC, higher levels of total Cat X significantly correlated to shorter overall survival (HR=2.08, 95% CI:1.07–4.05, p=0.028). Conclusions Total serum Cat X could be a useful prognostic indicator for determining survival of patients with CRC. Increased serum levels of total Cat X may reflect more aggressive tumour cell phenotypes and suggest the involvement of Cat X in processes involved in later stages of tumour progression.

    Full Text Available We reviewed the literature regarding the serum levels of the enzymes aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase in patients with chronic kidney disease on hemodialysis with and without viral hepatitis. Original articles published up to January 2013 on adult patients with chronic kidney disease on hemodialysis were selected. These articles contained the words “transaminases” “aspartate aminotransferase” “alanine aminotransferase” “gamma glutamyl transferase,” “liver enzymes”, AND “dialysis” OR “hemodialysis”. A total of 823 articles were retrieved. After applying the inclusion and exclusion criteria, 49 articles were selected. The patients with chronic kidney disease on hemodialysis had reduced serum levels of aminotransferases due to hemodilution, lower pyridoxine levels, or elevated homocysteine levels. The chronic kidney disease patients on hemodialysis infected with the hepatitis C virus also had lower aminotransferase levels compared with the infected patients without chronic kidney disease. This reduction is in part due to decreased viremia caused by the dialysis method, the production of a hepatocyte growth factor and endogenous interferon-α, and lymphocyte activation, which decreases viral action on hepatocytes. Few studies were retrieved on gamma-glutamyl transferase serum levels; those found reported that there were no differences between the patients with or without chronic kidney disease. The serum aminotransferase levels were lower in the patients with chronic kidney disease on hemodialysis (with or without viral hepatitis than in the patients with normal renal function; this reduction has a multifactorial origin.

    Full Text Available OBJECTIVE: To find an association between basic characteristics, seasons as well as disease types and 25-Hydroxyvitamin D serum concentrations in Chinese patients. METHODS: We randomly selected 5470 Chinese patients with various diseases, who were hospitalized between May 2012 and August 2013 in Shanghai and analyzed their serum 25-Hydroxyvitamin D2 (25 (OHD2 and 25-Hydroxyvitamin D3 (25(OHD3 concentrations with liquid chromatography-tandem mass spectrometry (LC-MS/MS as well as their parathyroid hormone (PTH and serum creatinine blood levels. The resulting data were analyzed by linear regression and variance analyses or multivariate analysis with covariance. RESULTS: The 25(OHD serum concentrations were lowest in December. Among the subjects with a median age of 83.0 ± 16.0, the median 25(OHD2, 25(OHD3 and total 25(OHD serum concentrations were 1.00 ± 1.80 ng/ml, 12.20 ± 8.50 ng/ml and 14.80 ± 9.80 respectively, indicating a prevalent 25(OHD deficiency. According to our multivariate analysis of covariance, the factors affecting 25(OHD2 and 25(OHD3 serum concentrations included age, creatinine, PTH, season and type of disease, whereas gender correlated only with 25(OHD2 and 25(OHD2 and D3 values correlated negatively with each other. Our results further revealed that 25(OHD3 levels were low while 25(OHD2 levels were high among patients with lung diseases, dyskinesia and coronary heart diseases. In addition, participants with diabetes and cerebral infarction had higher 25(OHD3 serum concentrations compared with lung disease patients. CONCLUSION: Vitamin D intake particularly during winter and summer seasons is important especially for elderly lung disease, dyskinesia and coronary heart disease patients to improve their quality of life.

    Serum magnesium (Mg) levels have been associated with muscle performance in the general population. We hypothesized that serum Mg would be associated with muscle quality in hemodialysis patients. A total of 310 patients were examined (age: 58 ± 12 years, hemodialysis duration: 6.4 ± 6.0 years, 60.6% men, and 36.1% diabetics). Arm lean mass was measured by dual energy X-ray absorptiometry (DXA) on the dominant side. Arm muscle quality was defined as the ratio of the handgrip strength to the arm lean mass of the same side (kg/kg). Serum Mg was 1.15 ± 0.16 mmol/L (2.8 ± 0.4 mg/dL), being higher than the reference range of normal subjects. There was a significant negative correlation between muscle quality and age (r = -0.326, p<0.0001) and duration of hemodialysis (r = -0.253, p<0.0001). The muscle quality of the diabetics was significantly lower than that of the non-diabetics (p<0.001). There was a significant, positive correlation between muscle quality and serum Mg (r = 0.118, p<0.05), but not serum calcium or phosphate. In multiple regression analysis, age, gender, hemodialysis duration, diabetes, and serum Mg (β = 0.129, p<0.05) were significantly and independently associated with muscle quality (R(2) = 0.298, p<0.0001). These results demonstrated that a lower serum Mg concentration was significantly associated with poor muscle quality in hemodialysis patients. Further studies are needed to explore the mechanism by which lower serum Mg affects muscle quality.

    Full Text Available Abstract Background Hantaviruses are the causative agents of two zoonotic diseases: hemorrhagic fever with renal syndrome (HFRS and hantavirus cardiopulmonary syndrome (HCPS. The pathogenesis of HFRS is poorly understood. However, it has been suggested that immune mechanisms, including cytokines, might have an important role in HFRS pathogenesis. Thus, the aim of our study was to investigate cytokine profiles in serum samples of HFRS patients from Slovenia and explore a possible correlation between cytokine levels and disease severity. Methods Acute-phase serum samples from 52 patients, diagnosed with DOBV infection, and 61 patients, diagnosed with PUUV infection, were included in this study. Patients were divided into two groups - severe or mild - based on disease severity. Levels of IL-10, IL-12, INF-γ and TNF-α were measured in the serum samples with commercial ELISA tests. Results Increased levels of IL-10, INF-γ, and TNF-α were found in almost all the serum samples tested. On average, higher concentrations were detected in patients infected with DOBV than PUUV. Furthermore, significantly higher levels of IL-10 (P = 0.001 and TNF-α (P = 0.003 were found in patients with a more severe clinical course of disease. The same association between IL-10 (P P = 0.021, and the severity of the disease was observed also when only patients infected with DOBV were considered. No differences in cytokine concentrations according to disease severity were observed in patients infected with PUUV. Concentrations of serum IL-12 in HFRS patients were in the normal range, however, higher levels were detected in patients infected with PUUV than in patients infected with DOBV. Conclusions We suggest that imbalance in production of proinflammatory and regulatory cytokines might be in part responsible for a more severe course of HFRS.

    2015-09-01

    To evaluate the relationship between serum concentrations of mono-hydroxy-carbazepine (MHD), the main metabolite of oxcarbazepine (OXC), and the occurrence of adverse effects (AE) in a large group of patients on OXC monotherapy. An antiepileptic drug (AED) therapeutic drug monitoring (TDM) database was analyzed especially with regard to OXC dosage, MHD serum concentration, and the occurrence of AE. In total, 893 blood samples of 442 patients were included in this retrospective study. The statistical evaluation was performed by means of Kaplan-Meier estimates, log-rank tests and generalized estimating equations (GEE). At least one AE was reported in 78 (17.6%) of the 442 patients. At MHD serum concentrations of 30.0 μg/ml and 43.7 μg/ml and OXC dosages of 33.1 mg/kg and 62.3 mg/kg, 25% and 75% of patients, respectively, experienced at least one AE. Log-rank tests indicated that younger patients (<18 years) may be able to tolerate higher MHD serum levels (p = 0.006) and higher OXC dosages per body weight (p < 0.001) compared to adult patients (≥ 18 years). Furthermore, AEs occurred at higher body-weight adjusted OXC dosages of extended release formulations compared to immediate-release formulations (p = 0.010), whereas MHD serum levels at which AEs occurred did not differ significantly between formulations (p = 0.125). Multivariate GEE confirmed the results. The occurrence of AEs is significantly (and non-linearly) dependent on MHD serum level, whereas the dependence of OXC dosage is less distinctive. But, tolerability of OXC seems to depend on age of the patients as well as on pharmaceutical formulation of OXC. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd.

    The present study was undertaken to explore the possible role of serum lipid profile in gallstone formation. For this serum lipid profile such as total, free and bound cholesterol, LDL cholesterol, HDL cholesterol, triacylglycerols and total lipids were determined in 109 gallstone patients and 100 controls (matched for age, sex and with negative personal or family history of gallstones) treated at Liaquat University Hospital, Jamshoro, Pakistan. Comparison for serum lipid profile between different groups of gallstone patients and controls revealed no significant variation except for the triacylglycerols and total lipids, which were differed significantly between females of up to 45 and above 45 years age. Comparison for serum lipid profile between pure cholesterol and mixed composition gallstone formers showed no significant difference (p>0.05) between the two groups. The serum lipid profile significantly varied between gallstone patients and controls except bound cholesterol level. Comparison of total cholesterol, free cholesterol, LDL cholesterol, HDL cholesterol, triacylglycerols and total lipids between gallstone patients and controls revealed that there was a significant difference between gallstone patients and controls for (a) females with or without gallstones, (b) females of up to 45 years age and (c) females having more than 3 children. HDL cholesterol is significantly decreased in all the groups of gallstone patients as compared to controls, whereas, bound cholesterol remained non significant in all the groups of gallstone patients when compared with controls. In conclusion, elevated serum total cholesterol, free cholesterol, LDL cholesterol, triacylglycerols and decreased levels of HDL cholesterol seem to play major contributing role in the pathogenesis of gallstones in females of up to 45 years age with more than three children.

    Full Text Available Objectives: Interleukin (IL-33 is a cytokine with both pro- and anti-inflammatory effects involved in the pathogenesis of some inflammatory diseases. The purpose of this investigation was to evaluate the serum and cerebrospinal fluid (CSF IL-33 concentrations in patients with multiple sclerosis (MS. Methods: Blood specimens were obtained from 140 patients with MS (46 males and 94 females with various disease patterns and treatment plans and 140 healthy subjects (47 males and 93 females, who acted as a control group. CSF samples were collected from 20 MS group and 20 sex- and age-matched patients with other neurological diseases of nonautoimmune etiology. The serum and CSF concentrations of IL-33 were measured by the enzyme-linked immunosorbent assay. Results: The serum and CSF IL-33 levels were significantly higher in the MS group compared to the control group (p<0.001 and p<0.050, respectively. The serum IL-33 concentrations were also significantly higher in newly diagnosed (untreated patients and patients treated with methylprednisolone or with interferon-β and methylprednisolone compared to the healthy patient group (p<0.007, p<0.002, and p<0.010, respectively. Moreover, the serum IL-33 concentrations in patients with relapsing-remitting (RRMS, primary progressive (PPMS, and secondary progressive (SPMS forms of the disease were significantly higher than in the healthy control group (p<0.006, p<0.001, and p<0.020, respectively. Conclusions: Our results showed increased concentrations of IL-33 in patients with MS including both untreated and treated MS patients and patients with the RRMS, SPMS, and PPMS forms. This suggests that IL-33 may be involved in the pathogenesis of all MS forms and treatment with methylprednisolone or both interferon-β plus methylprednisolone has no influence on IL-33 concentrations.

    Uric acid acts as both a pathogenic inflammatory mediator and an antioxidative agent. Several studies have shown that uric acid level correlates with the incidence, severity, and prognosis of pulmonary diseases. However, the association between uric acid level and acute respiratory distress syndrome (ARDS) has not been studied. This study was conducted to elucidate how serum uric acid level is related with clinical prognosis of ARDS. A retrospective cohort study with propensity score matching was conducted at a medical intensive care unit of a tertiary teaching hospital. The medical records of patients diagnosed with ARDS admitted from 2005 through 2011 were reviewed. Two hundred thirty-seven patients with ARDS met the inclusion criteria. Patients with a serum uric acid level uric acid group, and those with a level ≥3 mg/dL were classified into the normal to high uric acid group. We selected 40 patients in each group using propensity score matching. A higher percentage of patients in the low uric acid group experienced clinical improvement in ARDS. More patients died from sepsis in the normal to high uric acid group. Kaplan-Meier analysis showed that a low serum uric acid level was significantly associated with better survival rate. In patients with ARDS, a low serum uric acid level may be a prognostic marker of a low risk of in-hospital mortality.

    Vitamin D deficiency has been associated with an increased risk of depression and schizophrenia. The aim was to compare serum levels of vitamin D, calcium, phosphorus and parathyroid hormone in schizophrenics, depressed patients and healthy subjects in an Iranian population. In a cross-sectional study, 100 patients with schizophrenia and 100 with major depression were enrolled. A questionnaire was filled by using medical records of patients. After that a serum sample was taken and levels of vitamin D, calcium, phosphorus and parathyroid hormone were assessed and then compared between the three groups. Post-hoc analysis of Tukey showed that vitamin D level in healthy participants was significantly higher than depressed patients and schizophrenics while there was no significant difference between vitamin D level in depressed and schizophrenic patients. The findings suggest that vitamin D affects the brain independent of hormonal pathways which regulate serum level of calcium. Non-significant difference in the serum level of vitamin D between the schizophrenics and the depressed patients suggests that the independent effect of vitamin D in brain is a general effect and is not specialized to a specific region or pathway in the brain; however, differences between psychiatric and non-psychiatric patients might be resulted from differences in psychosocial backgrounds.

    Objective: To explore the role of the cytokines interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the neuroimmune modulation of epilepsy through measurement of the changes of the serum levels of the these cytokines after drug therapy in epileptic patients. Methods: Serum IL-2, IL-6, TNF-α levels were measured with RIA in 43 patients with epilepsy both before and after drug therapy for 3-6 months as well as 32 controls. Results: Before treatment, serum levels of these cytokines in the patients were significantly higher than those in the controls (p<0.001). After treatment, 18 of the 43 patients were regarded as treatment very successful, with attack numbers decreased more than 75%. Some of this group of patient had their serum cytokines levels significantly dropped down, but the mean level for the group as a whole did not change much. In the rest 25 patients with less successful result, changes were not significant with the levels increased in a few cases. Among the cytokines, levels of IL-2 were significantly positively correlated to those of IL-6 and TNF-α (r=0.47, p<0.01, r=0.55, p<0.01). Conclusion: Increased levels of the cytokines in the epileptic patients suggest an activated immune state. However, the changes of levels after therapy are not predictable and do not necessarily drop down significantly even with very successful treatment

    Objective: To investigate the serum expression of IGF-I in patients with astrocytoma of different degrees of malignancy as well as the changes of levels after operative removal of the tumor. Methods: Serum IGF-I contents were measured with IRMA in 16 patients with Grade I-II astrocytoma and 14 patients with Grade III-IV astrocytoma both before and after operation as well as in 30 controls. Results: The serum contents of IGF-I in both groups of patients were significantly higher than those in controls (P<0.05). The levels in Grade III-IV patients were significantly higher than those in Grade I-II patients (P < 0.05 ). After operation, the levels dropped significantly (vs before operation, P<0.05). Conclusion: The serum contents of IGF - I in patients with astrocytoma were positively correlated with the degree of malignancy. Post-operative decrease of IGF-I contents was related to the decrease of tumor burden. (authors)

    Methods: The study was designed to compare the effectiveness of emotional support focused nurse directed intervention in terms of verbal, written and telephone basis on serum cortisol among breast cancer patients in Cancer Centre at Erode. Participants were randomly allocated by using Sequentially Numbered Opaque Sealed Envelope (SNOSE method. 2 ml of blood samples were collected from 30 breast cancer patients who were selected randomly by adopting random number table, 10 in each experimental arm during evening at 18 hour; radioimmunoassay method was used to measure the level of serum cortisol before and after intervention. The intervention was given twice in a week for the duration of 30-45 minutes, in which early 20-30 minutes spares to express thoughts and feelings of the participants and subsequent 10-15 minutes for rendering informational support and later follow up session for the period of 1 month. Results: Emotional support was effective in reducing serum cortisol level among breast cancer patients. There was no statistically significant difference between arms on serum cortisol levels. Conclusions: Marginal differences were noted between posttest mean scores of serum cortisol among verbal, written and telephone arms. Further emotional support can be rendered according to the preference of the breast cancer patients.

    Klotho deficiency is associated with several metabolic disorders. Two dimensional (2D) longitudinal strain (LS) of left ventricle (LV), carotid artery intima-media thickness (CIMT), flow-mediated dilation (FMD) of brachial artery and epicardial fat thickness (EFT) have been reported to be early predictors of atherosclerosis. We aimed to investigate the relationship between serum Klotho levels and these early predictors of atherosclerosis in patients with type 1 diabetes mellitus (DM). The study included 45 type 1 diabetic patients and 35 controls. Serum Klotho levels were determined by ELISA method. The patient group was also divided into two subgroups according to serum Klotho levels: high (HK) and low Klotho (LK) groups. EFT, CIMT and FMD were measured according to appropriate recommendations. Speckle tracking analysis was performed using the Echopac software. The patient group had significantly lower serum Klotho (p=0.001), FMD (p1) and LS of LV (p1) values, but larger EFT (p1) and CIMT (p1) values than controls. LK subgroup had also significantly lower FMD (p1) and LS of LV (p1) but larger EFT (p=0.002) and CIMT (p1) values than HK subgroup. Serum Klotho may have a protective effect against atherosclerosis and endothelial dysfunction in type 1 DM. Copyright © 2016 Elsevier Inc. All rights reserved.

    An inflammatory response plays a crucial role in myocardial damage after an acute myocardial infarction. To measure serum concentrations of several mediators in patients with an acute myocardial infarction (STEMI) and to assess their potential relationship with a risk of coronary instability. The 33 patients with STEMI and 19 healthy volunteers were analyzed. The clinical data were obtained; as well serum concentrations of tryptase, endothelin (ET-1), angiogenin, soluble c-kit, and PDGF were measured. Patients with STEMI had higher serum tryptase and ET-1 than healthy volunteers (2,5 ± 0,4 ng/mL versus 1,1 ± 0,4 ng/mL and 0,7 ± 0,1 ng/mL versus 0,3 ± 0,1 ng/mL, resp.). Subjects with significant lesion in left anterior descending artery (LAD) had lower serum ET-1 compared to those with normal LAD (0,6 ± 0,2 pg/mL versus 0,9 ± 0,4 pg/mL). Patients with three-vessel coronary artery disease (CAD) had higher level of soluble c-kit compared to those with one- or two-vessel CAD: 19,9 ± 24,1 ng/mL versus 5,6 ± 1,9 ng/mL. Elevated serum tryptase and ET-1 may be markers of increased coronary instability; some cytokines may be related to the extension of CAD.

    Background. Obesity is considered a low-grade inflammatory state and has been associated with increased acute phase proteins as well as changes in serum fatty acids. Few studies have assessed associations between acute phase proteins and serum fatty acids in morbidly obese patients. Objective. To investigate the relationship between acute phase proteins (C-Reactive Protein, Orosomucoid, and Albumin) and serum fatty acids in morbidly obese patients. Methods. Twenty-two morbidly obese patients were enrolled in this study. Biochemical and clinical data were obtained before bariatric surgery, and fatty acids measured in preoperative serum. Results. Orosomucoid was negatively correlated with lauric acid (P = 0.027) and eicosapentaenoic acid (EPA) (P = 0.037) and positively with arachidonic acid (AA) (P = 0.035), AA/EPA ratio (P = 0.005), and n-6/n-3 polyunsaturated fatty acids ratio (P = 0.035). C-Reactive Protein (CRP) was negatively correlated with lauric acid (P = 0.048), and both CRP and CRP/Albumin ratio were negatively correlated with margaric acid (P = 0.010, P = 0.008, resp.). Albumin was positively correlated with EPA (P = 0.027) and margaric acid (P = 0.008). Other correlations were not statistically significant. Conclusion. Our findings suggest that serum fatty acids are linked to acute phase proteins in morbidly obese patients. PMID:24167354

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

    Ghrelin is a gastric hormone that posses multiple functions, including induction of growth hormone release, regulation of proinflammatory cytokines and control of food intake and energy homeostasis. A few reports on serum ghrelin level in chronic inflammatory states revealed contradictory results. The study was undertaken to determine ghrelin in patients with rheumatoid arthritis receiving infliximab, a TNF-α blocking agent. Serum ghrelin was determined in 18 female rheumatoid patients before the treatment with infliximab, 1 week after the first infusion and after 53 weeks of medication and compared with 15 age-matched healthy women. Serum ghrelin level was shown to be increased in the patients. A decrease in serum ghrelin level was found after the first infusion of infliximab and similarly decreased ghrelin level but still higher than in the control was shown in the 53rd week of medication. The obtained results suggest that ghrelin level is related to inflammation, and its serum level in patients with severe rheumatoid arthritis behaves similarly to acute-phase reactants.

    Oxidative stress and variations in antioxidant status are implicated in the pathogenesis of inflammatory and autoimmune diseases. Polymyositis and dermatomyositis (PM/DM) are autoimmune diseases with inflammatory cells infiltrating into skeletal muscles, and the antioxidant status is still controversial. The aim of our study was to investigate the correlation between PM/DM and the antioxidant status of serum bilirubin (Tbil, Dbil and Ibil) and uric acid (UA). We measured serum concentrations of bilirubin (Tbil, Dbil and Ibil) and uric acid in 384 individuals, including 110 PM/DM patients and 274 healthy controls. We found that PM/DM patients had significantly lower serum concentrations of bilirubin (Tbil and Ibil) and uric acid than healthy controls, whether male or female. Also, after separately adjusting the covariances of age and gender, Tbil, Dbil, Ibil and UA were all relevant factors for PM/DM. Moreover, there were no significant differences in serum antioxidant molecule levels between PM and DM subgroups. Our study demonstrated the low serum levels of bilirubin and uric acid in patients with PM/DM. This suggested low antioxidant status in PM/DM patients with excessive oxidative stress.

    There is an increased evidence of an association between inflammatory mediators, particularly serum IL-6, depression and cognitive impairment in the elderly. This study aims at exploring the relation of peripheral IL-6 to cognitive functions in elderly patients with major depressive disorder (MDD). (1) Assessment of serum IL-6 levels and cognitive functions in elderly patients suffering from major depression and comparing them to healthy age-matched control subjects; (2) correlation between serum IL-6 levels and clinical characteristics of depression and cognitive functions in these patients. The study is an observational, case-control study. It consisted of 80 subjects, 40 with the diagnosis of MDD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM IV-TR) with early onset (first episode before the age of 60) and 40 community-dwelling subjects. They were subjected to the Structured Clinical Interview according to DSM-IV, Montreal Cognitive Assessment, Montgomery Asberg Depression Rating Scale, and serum IL-6 assay using ELISA. In the depression group, subjects had lower scores in cognitive testing, than the control group (p = 0.001). Serum IL-6 was found to have a negative correlation with cognitive testing in these patients even after controlling for the severity of depressive status and Body Mass Index (BMI) (p = 0.025). MDD in elderly subjects is associated with decline in cognitive functions that may be related to peripheral IL-6 levels.

    Functional hypothalamic disturbances may be the cause of secondary amenorrhea and are related to aberration in both the pattern of pulsatility and amplitude in the release of gonadotropin-releasing hormone (GnRH) in hypothalamus. Inhibin B, as an ovarian peptide plays a crucial role in reproduction function throughout regulation of folliculotropin (FSH) pituitary production and inhibiting GnRH secretion during the menstrual cycle. To measure and estimate serum inhibin B concentration in patients with functional hypothalamic amenorrhea. Material and methods. The study included 41 women suffering from functional hypothalamic amenorrhea. Secondary amenorrhea was defined as the lack of menstruation lasting at least 90 days not due to pregnancy, characterized by low serum concentrations of lutropin (LH < 5 mIU/ml)) and typical for functional hypothalamic disturbances anamnestic investigation. The control group consists of 40 healthy women with normal menstrual cycles and Body Mass Index (BMI between 18.5- 24.9 kg/m2). Medical history, examination and laboratory analysis of LH, FSH, estradiol (E), prolactin, testosterone and inhibin B were performed (ELISA--enzyme-linked immunosorbent assay). There are statistically lower serum inhibin B, FSH, LH, estradiol and prolactin concentrations in patients with functional hypothalamic amenorrhea in comparison to healthy women. Positive correlation between serum concentration of inhibin B and estradiol concentration was found in patients with functional hypothalamic amenorrhea. Patients with functional hypothalamic amenorrhea are characterized by statistical significant decrease in serum inhibin B concentration in comparison to the control group.

    To study the changes in bone metabolic parameters and serum thyroid hormone levels in patients with hyperthyroidism, seventy patients with hyperthyroidism and sixty healthy controls were investigated by means of radioimmunoassay (RIA) for serum ICTP, chemiluminescent immunoassay for BAP and serum thyroid hormone and meanwhile bone mineral density was measured. The results showed that the levels of serum BAP, ICTP and thyroid hormone in patients with hyperthyroidism were dramatically higher than those in control group (all P<0.01), BMD was significantly decreased in the study group (P<0.01). The correlation analysis showed that both BAP and ICTP were negatively correlated with BMD (all P<0.05). The results from this investigation indicated that increased bone turnover is significantly associated with an increased thyroid hormone in patients with hyperthyroidism, and bone resorption is greater than formation resulting in a bone mass loss. Measurement of serum BAP and ICTP levels may be of help to judge the severity of bone metabolism, study the state of an illness in hyperthyroidism

    To determine effects of the biochemical and cytological properties of blood, serum, and ascites on survival of patients with malignant peritoneal effusion (MPeE), including malignant peritoneal mesothelioma (MPeM) and peritoneal carcinomatosis (PC), we conducted a retrospective study of patients with MPeE and healthy controls. Potential prognostic factors were identified as follows: age, sex, blood neutrophil-to-lymphocyte ratio (NLR), serum parameters, ascites parameters, serum-ascites albumin gradient, and the ascites-serum LDH ratio. Compared to those of the control group, serum albumin levels were significantly lower, and the NLR and serum LDH levels were significantly higher in the MPeE group. Overall survival (OS) was longer in patients with MPeM compared to that in patients with PC. Compared with patients in the MPeM, patients with PC had higher NLRs, ascites glucose levels, serum-ascites albumin gradients, and serum LDH levels. In contrast, their ascites albumin levels and ascites-serum LDH ratios were lower. Univariate analyses indicated that the NLR, serum LDH levels, ascites LDH levels, ascites coenocyte levels, and the ascites coenocyte-to-monocyte ratios affected the OS. Multivariate analyses identified only serum and ascites LDH levels as independent prognostic factors.

    Background: There is a renewed interest in adrenal function during severe sepsis. Most studies have used total serum cortisol levels; however, only free serum cortisol is biologically active. The aim of this study was to determine the validity of salivary cortisol levels as a surrogate for free serum cortisol levels during septic shock. Methods: Fifty-seven patients with septic shock were studied to determine the correlation between total serum cortisol and salivary cortisol to free serum cortisol levels. Thirty-eight patients were included in the salivary to free serum cortisol correlation. Salivary cortisol level was tested by enzyme immunoassay. Serum total cortisol, free cortisol, and cortisol-binding globulin (CBG) levels were determined by liquid chromatography-mass spectrometry, equilibrium analysis, and radioimmunoassay, respectively. Results: The mean ± SD age was 56.6 ± 18.5 years. Fifty-seven percent were women. APACHE (Acute Physiology and Chronic Health Evaluation) II score median was 26, Simplified Acute Physiology Score II median was 61, and Sequential Organ Failure Assessment median was 13. The correlation between salivary and free serum cortisol levels was 0.79 (95% CI, 0.63-0.89; P cortisol and total serum cortisol levels was 0.86 (95% CI, 0.78-0.92; P cortisol level was 2.27 ± 1.64 μg/dL. The mean ± SD salivary cortisol level was 2.60 ± 2.69 μg/dL. The mean ± SD total serum cortisol level was 21.56 ± 8.71 μg/dL. The mean ± SD CBG level was 23.54 ± 8.33 mg/dL. Conclusions: Salivary cortisol level can be used as a surrogate of free serum cortisol level in patients with septic shock with very good correlation. Salivary cortisol testing is noninvasive, easy to perform, and can be conducted daily. Trial registry: ClinicalTrials.gov; No.: NCT00523198; URL: www.clinicaltrials.gov PMID:21816912

    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.

Although inflammation has an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD, little is known regarding the relationship between serum CyPA and COPD. Methods: Ninety-three COPD patients with acute exacerbation were enrolled in the study and were reassessed during the convalescence phase. Eighty-eight controls were matched for age, gender, body mass index, smoking index and comorbidity. The basic clinical information and pulmonary function of all participants were collected. Serum levels of CyPA and other inflammation indexes were further measured. Results: Serum CyPA was significantly increased in convalescent COPD patients compared to healthy controls, and further elevated in COPD patients with acute exacerbation. Serum CyPA positively correlated with serum interleukin-6, matrix metalloproteinase-9 and high-sensitivity C-reactive protein in both the exacerbation and convalescence phases of COPD. Furthermore, it negatively correlated with percent value of forced expiratory volume in 1 second (FEV1% predicted and FEV1/forced vital capacity in convalescent COPD patients. Conclusion: These results suggest that serum CyPA can be used as a potential inflammatory biomarker for COPD and assessment of serum CyPA may reflect the severity of inflammation in COPD.

    Full Text Available The prostatic adenocarcinoma is one of the most frequent malignant tumors of men over 50 years of age. It is distinguished by agressive clinical course and heterogeneous multifocal hystomorphologic changes. PSA is the most reliable serum marker in diagnostics and observation of prostatic carcinoma and gleason's system of tumor-diferentiation grading is generally accepted way of determining the hystologic grade. Gleason's system is correlated with serum levels of PSA and with biological behaviour of the tumor. We presented 40 patients with verified ACP in whom the level of serum PSA, gleason's grade and score were compared. Highly significant correlation was found between serum level of PSA and the differentation grade of the tumor - Gleason's grade and score. Combination of PSA parameters and Gleason's score enables correct estimation of tumor's behaviour and correct therapeutic protocole.

    Full Text Available Background: Bone sarcomas are extremely malignant prone to rapid hematogenic metastasing. Evaluation of biological marker expression by the tumor is important not only for the search of new potential chemotherapy targets, but for the assessment of the disease prognosis.Aim: A comparative evaluation of matrix metalloproteinases (MMP-2, -7, -9 and tissue inhibitor of metalloproteinase-1 (TIMP-1 in the serum of patients with primary bone tumors and in healthy people to identify their potential association with the histological characteristics of the tumor and the disease prognosis.Materials and methods: A comparative study of serum MMP-2, -7, -9, and TIMP-1 levels was performed in 54 patients with primary bone tumors (malignant, 45 patients, including central osteosarcoma in 21, periosteal osteosarcoma in 4, Ewing's sarcoma in 11, primary chondrosarcoma in 6, undifferentiated pleomorphic sarcoma in 3, and borderline giant cell tumors in 9 and in 26 healthy individuals with the use of the immunoenzyme technique (Biosource, USA, for TIMP-1 and R&D, USA, for MMP-2, -7, and -9. Results: The TIMP-1 levels in the serum of patients with central and periosteal osteosarcomas were significantly higher than in the serum of healthy controls (р = 0.038 and p = 0.007, respectively. The MMP-9 levels in patients with bone malignancies were significantly lower than that in the normal controls (p < 0.05. There was a positive correlation between serum TIMP-1 and MMP-9 levels in patients with central, periosteal and Ewing's sarcomas (r = 0.37, p = 0.024. No significant differences in the 5-year survival rates related to serum TIMP-1, MMP-2, -7, -9 levels were found in patients with bone sarcomas. However, in those with osteosarcoma and serum MMP-2 > 160 ng/ml, the overall 5-year survival rate was 1.6-fold higher than in those with lower MMP-2 levels, and in those with ММP-9 levels < 377 ng/ml, the 5-year survival rate was 1.4-fold higher than in patients with

    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.

    Serum testosterone measurement is recommended to assess the efficacy of androgen deprivation therapy (ADT) and to diagnose castration resistance in patients with prostate cancer (PCa). Currently, the accepted castrate level of serum testosterone is 50 ng/dL. Liquid chromatography and tandem mass spectrometry (LC MSMS) is the appropriate method to measure testosterone, especially at low levels. However, worldwide, chemiluminescent assays (CLIAs) are used in clinical laboratories, despite their lack of accuracy and reproducibility, because they are automatable, fast, sensitive, and inexpensive. We compared serum testosterone levels measured using LC MSMS and CLIAs in 126 patients with PCa undergoing luteinizing hormone-releasing hormone (LHRH) agonist therapy. The median serum testosterone level was 14.0 ng/dL (range, 2.0-67.0 ng/dL) with LC MSMS and 31.9 ng/dL (range, 10.0-91.6 ng/dL) with CLIA (P  50 ng/dL in 3 patients (2.4%). These ranges were found in 34 (27%), 72 (57.1%), and 20 (15.9%) patients when testosterone was measured using CLIA (P < .001). The castrate level of serum testosterone using LC MSMS and CLIA was 39.8 ng/dL (95% confidence interval [CI], 37.1-43.4 ng/dL) and 66.5 ng/dL (95% CI, 62.3-71.2 ng/dL), respectively. We found that CLIA overestimated the testosterone levels in PCa patients undergoing LHRH agonist therapy. Thus, the castration level was incorrectly considered inadequate with CLIA in almost 15% of patients. The true castration level of serum testosterone using an appropriate method is < 50 ng/dL.

    Increased pre- and posttransplantation values of soluble CD30 (sCD30) have been shown to be associated with acute kidney transplant rejection. We sought to study whether high sCD30 could predict rejection early after liver transplantation. The study population included 54 consecutive liver transplant patients, whose samples were collected before liver transplantation and at discharge, which was at a mean time of 3 weeks after transplantation. During the first 6 months posttransplantation, 22 patients experienced an acute rejection episode. Serum sCD30 concentrations were measured by an enzyme-linked immunoassay; changes in serum sCD30 levels posttransplantation were also expressed as relative values compared with pretransplantation results. Liver patients before transplantation displayed higher serum sCD30 values compared with healthy controls: mean values +/- SD were 93 +/- 58 IU/mL vs 17 +/- 8 IU/mL, respectively. At 3 weeks after transplantation the mean sCD30 concentration in liver transplant patients decreased to 59 +/- 42 IU/mL (P = .005). The mean pretransplantation serum sCD30 value was slightly lower among rejecting vs nonrejecting patients: 78 +/- 43 IU/mL vs 104 +/- 65 IU/mL (P = NS). Posttransplantation values in both groups decreased significantly: 47 +/- 34 IU/mL in patients with rejection (P = .014) vs 69 +/- 45 IU/mL in patients without rejection (P = .012). The relative value at 3 weeks posttransplantation decreased slightly more among patients with vs without rejection (70% vs 88%; NS). No correlation was found between serum sCD30 and anti-HLA class I antibodies or crossmatch positivity. In conclusion, neither pre- nor posttransplantation sCD30 levels were associated with acute rejection in liver transplant patients.

    To study the cause for slow recovery in male hyperthyroidism patients after treated with ATD, the changes of serum β 2 -MG, TGAb and TMAb were measured by RIA. A total of 164 male hyperthyoidism patients were divided into 3 groups by their different therapeutic effects: untreated patients (group B, n=65), treated but unrelieved patients (group C, n=52), treated and recovered patients (group D, n=47) and 58 normal persons serving as controls (group A). The results indicated that the levels of serum β 2 -MG, FT 3 and FT 4 were significantly higher in group B and C than those in group A (P 3 or FT 4 and β 2 -MG respectively in group B and C. There was no significant difference in β 2 -MG, FT 3 and FT 4 between group D and A (P>0.05). And there was no difference in the positive rates of TGAb and TMAb between group D and C(P>0.05). The serum β 2 -MG was still higher in 19.1% patients and the positive rates of TGAb and TMAb were also higher in 23.4% patients. These results suggest that β 2 -MG, TGAb and TMAb could act as serum markers of immunological remission for male hyperthyroidism patients and the determination of β 2 -MG, TGAb and TMAb could be benifical to monitoring therapeutic effect. The cause for slow recovery in about 20% male hyperthyroidism patients might be due to higher serum β 2 -MG and higher positive rates of TGAb and TMAb. (authors)

    Full Text Available Introduction: High plasma cholesterol levels, mainly LDL are a widely recognized major risk factor for Coronary Heart Disease (CHD. According to the epidemiologic studies findings, people from the Mediterranean countries, have lower CHD rats than other countries, in these countries usual diet is high in olive oil. The present study compares the effects of cholesterol enriched diet with or without adding olive oil on serum Lipoproteins, lipid per oxidation, and atherosclerosis development. Method: Twenty Dutch male rabbits were Categorized to four groups (one group as Control, and others as Experimental. They received one of standard, cholesterol - rich, olive oil rich and combined (cholesterol + olive oil diet for Twelve weeks. Fasting blood samples from heart were collected at the beginning, and the end of Experimental period. Means of total cholesterol, HDL-Ctriglycerides, MDA and antioxidant caperimental period, significant differences were showed in total cholesterol, HDL-C, triglyceride and MDA between groups. Results: The comparison of cholesterol rich diet with cholesterol + olive oil showed a higher mean of MDA in cholesterol rich group (P < 0.001. Biochemical factors and aortic lesion degree showed no significant difference between standard and olive oil group. Aortic lesions in cholesterol + olive oil showed nonsignificant lower degree than cholesterol group. Discussion: This findings showed preventive effect of olive oil against atherosclerosis which is independent of plasma lipoprotein effect, and suggested that probably olive oil acts on arteries directly.

    The purpose of this study was to investigate the association between serum leptin and pubertal derangement in β-thalassemia major (TM) patients. This study was conducted on forty TM patients (25 males and 15 females) with mean age 15.6 ±1.47 and twenty healthy children with normal pubertal development served as control (10 males and 10 females). Clinical, anthropometric and pubertal assessment using tanner classification were done for all patients and controls in addition to estimation of serum ferritin, leptin, follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) in boys and estradiol (E 2 ) in girls. Thalassaemic patients were subdivided into 27 patients with normal puberty and 13 delayed puberty patients. The results showed that failure of puberty was confirmed in 70% of boys and in 67% of girls. Body mass index (BMI) was significantly decreased in both patient groups as compared to controls. Mean serum ferritin levels were significantly increased in TM patients with delayed puberty (male: 2865.5±274.7 and female: 2704.5±477.1 ng/ml) than the levels in euogonadal patients (male: 1594.1±408.8 and female: 1524.1±349.6 ng/ml). However, a significant difference in serum ferritin was also detected between euogonadal patients and controls. Although the mean serum leptin levels were significantly higher in normal pubertal patients (male: 3.7± 0.4 and female: 7.6±1.2 ng/ml) comparing to the levels in delayed puberty patients (male: 0.9± 0.4 and female: 2.6±0.9 ng/ml), it was still lower than levels in control group (male: 8.4±2.8 and female: 12.3±1.9 ng/ml). The mean serum levels of FSH and LH were significantly decreased in delayed puberty patients when compared to each of normal puberty patients and controls. However, the comparison between normal patients and controls was non-significant. A close positive correlation was observed between serum leptin and BMI in normal pubertal patients, but such correlation was not obtained in

    Full Text Available Objective: To investigate the correlation between the serum albumin, prealbumin and ventilator dependence in patients with COPD. Methods: Serum albumin and prealbumin of 44 COPD patients using breathing machine>48 h were tested at admission, 1 week, 2 weeks treatment. According to the existence of ventilator dependence, divided the patients into the ventilator dependence group and the ventilator independence group, compare the albumin, prealbumin average of two groups, evaluate the correlation between the serum albumin, prealbumin and ventilator dependence in patients with COPD. Results: Albumin levels reduced in both groups after 1 week treatment, but there was no statistically significant difference. Albumin levels reduced in both groups after 2 weeks treatment, but more significantly in the ventilator dependence group, the difference had statistical significance. Prealbumin levels in the ventilator independence group after 1 week treatment didn’t reduced, but reduced in the ventilator dependence group, the difference was statistically significant. Prealbumin levels reduced in both groups after 2 weeks treatment, but more significant in the ventilator dependence group, the difference had statistical significance. Conclusion: Serum albumin and prealbumin levels were correlation with the ventilator dependence in patients with COPD. But prealbumin can more sensitively and more early predict the ventilator dependence in patients with COPD suffered from malnutrition.

    Serum Alkaline Phosphatase (ALP) was studied in relation to liver scintigrams of 54 patients with hepatocellular carcinoma. The ALP activity was higher with larger tumors and in multiple tumors. Within the single tumor group, the activity was higher when the tumor was located in the hilum than in the periphery. The incidence of ALP-1 isoenzyme (bile ALP) roughly paralleled the total ALP activity. These results suggest that the variation of serum ALP seen in each individual patients with hepatocellular carcinoma reflects the volume of cholestatic liver tissue, which is changed by the number, size and localization of the tumor nodules in the liver.

    Objective: To explore the auto-immune factors predisposing to developing hypothyroidism after 131 I treatment in patients with Graves' disease (GD). Methods: Eighty-eight GD patients treated with 131 I were followed for three years. These patients were of two groups: Group A (n=35), serum TGA, TMA, TRAb all positive before treatment; Group B (n=53) serum TGA, TMA negative but TRAb positive. Results: In Group A, 31.40% (n=11) of all the patients were hypothyroid three years after treatment. The result was much better in Group B, with only 3.8% (n=2) being hypothyroid. The difference was significant. Conclusion: GD patients with positive TGA, TMA were liable to develop hypothyroidism after 131 I treatment. Those patients should be treated with lesser amount of the drug accordingly

    A comparative radiommunoassay in the ratio of calcitonin and parathyroid hormone secretion was carried out in healthy controls (young and older than 40 years), patients with benign tumors, inflamatory processes and malignancies of the stomach, kidney, breast, prostate and lung. A significant increase in the ''calcitonin index'' (ratio of molar concentrations of calcitonin and parathyroid hormone) was established in patients with cancer of the breast, prostate and skeletal metastases of lung cancer, irrespective of the presence of primary tumor. This index is irrelevant in cases of gastric and renal carcinoma and cannot be used as indication of skeletal dissemination because of the predominant level of parathyroid hormone secretion.

    Copper homeostasis can be altered by inflammation. This study aimed to investigate the alteration of serum copper homeostasis and to explore its clinical significance in patients with chronic hepatitis B (CHB).Thirty-two patients with CHB and 10 aged- and sex-matched healthy controls were recruited. Analyses included serum levels of total copper (TCu), copper ions (Cu), small molecule copper (SMC), ceruloplasmin (CP), Cu/Zn superoxide dismutase 1 (SOD1), urinary copper, and the activities of serum CP and SOD1.The serum TCu and urinary copper levels in patients with CHB were significantly higher than the controls (P = .04 and .003), while the serum Cu was lower than the controls (P = .0002). CP and SOD1 activities in the serum were significantly lower in patients with CHB compared to controls (P = .005) despite higher serum concentrations. In addition, serum alanine aminotransferase inversely correlated with serum CP activity (P = .0318, r = -0.4065).Serum copper homeostasis was altered in this cohort of patients with CHB. The results suggest increased oxidative stress and impaired antioxidant capability in patients with CHB, in addition to necroinflammation. These results may provide novel insights into the diagnosis and treatment of patients with CHB.

    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 (E 2 ) 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)

    We evaluated the effect of hydrochlorothiazide in a sample of anuric patients on hemodialysis and found an increase in serum calcium, which occurred only in those with parathyroid hormone >300 pg/ml. This finding highlights the extra-renal effect of this diuretic and a possible role of parathyroid hormone in the mechanism. Thiazide diuretics are commonly used in patients with chronic kidney disease to treat hypertension. Their effects on calcium and bone metabolism are not well established, once calciuria may not fully explain levels of calcium and parathyroid hormone (PTH) in this population. A previous study has suggested that thiazides require the presence of PTH as a permissive condition for its renal action. In anuric patients, however, the role of PTH, if any, in the thiazide effect is unknown. To assess thiazide extra renal effect on serum calcium and whether such an effect is reliant on PTH, hydrochlorothiazide (HCTZ) 100 mg was given orally once a day to a sample of 19 anuric patients on hemodialysis for 2 weeks. Laboratories' analyses were obtained in three phases: baseline, after diuretic use, and after a 2-week washout phase. We demonstrated that serum calcium (Ca) increased in ten patients (52.6%) after HCTZ use, returning to previous levels after the washout period. Out of the 19 patients, ten presented PTH ≥ 300 pg/ml, and Ca has increased in eight of them, whereas in the other nine patients with PTH < 300 pg/ml, serum Ca has increased only in two individuals (RR risk of increase Ca 3.9; p = 0.012). HCTZ was capable of increasing serum Ca in a sample of anuric patients on hemodialysis and seems this effect is highly dependent on PTH levels. Caution is required while interpreting this result, as the small sample size might implicate in a finding caused by chance.

    The number of patients suffering from renal failure indicating dialysis has been increasing worldwide. Leptin hormone plays an important role in the development of malnutrition in these patients. Bone produces different hormones, such as osteocalcin (OC), which influences energy expenditure in humans. Disturbances in mineral metabolism and bone disease are common complications of chronic kidney disease (CKD). There are increasing evidences suggesting that these disorders in mineral and bone metabolism are associated with increased risk of cardiovascular calcification, morbidity, and mortality, especially among those who undergo maintenance renal dialysis. The present study was carried out to evaluate the importance of serum leptin assessment in renal dialysis patients. Serum leptin level was estimated by radioimmunoassay (RIA) using recombinant human leptin (Leptin- Human Ria-CT). Immunoradiometric assay kit (host IRMA) was used for in-vitro quantitative measurement of human intact OC. Serum creatinine level was determined by colorimetric method. This study included 60 patients (twenty suffering from CKD, thirty on dialysis and ten healthy controls). Serum leptin, OC and creatinine were found to be higher in patients of both groups compared to that of controls. Maximum increase was observed in patients on dialysis. From these results it is possible to conclude that, although patients with chronic renal disease exhibited significant increase in serum leptin, yet sudden additional increase can be related to serious pathology that can end in renal failure. The present study also highlighted the importance of OC as a marker of disturbed mineral-bone metabolism in chronic kidney disease (CKD) patients and those receiving dialysis that could lead to the atherosclerosis, extravascular calcification, morbidity and mortality.

    Cancer serum protein profiling by mass spectrometry has uncovered mass profiles that are potentially diagnostic for several common types of cancer. However, direct mass spectrometric profiling has a limited dynamic range and difficulties in providing the identification of the distinctive proteins. We hypothesized that distinctive profiles may result from the differential expression of relatively abundant serum proteins associated with the host response. Eighty-four antibodies, targeting a wide range of serum proteins, were spotted onto nitrocellulose-coated microscope slides. The abundances of the corresponding proteins were measured in 80 serum samples, from 24 newly diagnosed subjects with lung cancer, 24 healthy controls, and 32 subjects with chronic obstructive pulmonary disease (COPD). Two-color rolling-circle amplification was used to measure protein abundance. Seven of the 84 antibodies gave a significant difference (p < 0.01) for the lung cancer patients as compared to healthy controls, as well as compared to COPD patients. Proteins that exhibited higher abundances in the lung cancer samples relative to the control samples included C-reactive protein (CRP; a 13.3 fold increase), serum amyloid A (SAA; a 2.0 fold increase), mucin 1 and α-1-antitrypsin (1.4 fold increases). The increased expression levels of CRP and SAA were validated by Western blot analysis. Leave-one-out cross-validation was used to construct Diagonal Linear Discriminant Analysis (DLDA) classifiers. At a cutoff where all 56 of the non-tumor samples were correctly classified, 15/24 lung tumor patient sera were correctly classified. Our results suggest that a distinctive serum protein profile involving abundant proteins may be observed in lung cancer patients relative to healthy subjects or patients with chronic disease and may have utility as part of strategies for detecting lung cancer

    Background: Despite the high levels of inflammation in hemodialysis patients and the effects of diet on systemic inflammation, such as the development of atherosclerosis and cardiovascular disease, few studies have evaluated the relationship of macronutrients and antioxidants intake with serum C-reactive protein (CRP). Therefore, this study assessed the relationship between serum high sensitivity CRP (hs-CRP) with macronutrients and antioxidants intake and serum albumin. Methods: This cross-sectional study used census sampling to select 75 hemodialysis patients (35 men and 40 women) who attended the hemodialysis department of Vaseie Hospital of Sabzevar, Iran. After obtaining the written consent, all the patients were interviewed and dietary data was collected by using a semi-quantitative food frequency questionnaire including 160 food items. Diet analysis was performed with Nutritionist IV. Before being connected to the dialysis machine, 5 cc fasting blood samples were obtained from all participants and serum hs-CRP and albumin levels were measured. All the statistical analyses were conducted with SPSS -for Windows, version 16.0. Results: The patients' mean body mass index was 20.09 ± 3.27 kg/ m2. The participants' intake of antioxidants and all macronutrients, except for carbohydrates and proteins, was less than the standard levels. Moreover, the hs-CRP had significant inverse relationships with serum albumin (P=0.0001) and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy (P=0.002) and protein (P=0.0001). Conclusion: Our findings indicated hs-CRP levels of hemodialysis patients to have significant inverse relationships with serum albumin and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy and protein.

    Coronary artery disease (CAD) is the major cause of death nearly all over the world, and accurate and rapid diagnosis of CAD is of major medical and economic importance. The aim of this study was to evaluate the serum and saliva levels of cathepsin L in patients with acute coronary syndrome (ACS). In a cross-sectional study, 39 patients with ACS and 28 with controls were recruited to the study, and cathepsin L levels were measured in serum, resting saliva, and stimulated saliva obtained 12 and 24 h after the onset of ACS by ELISA method. Statistical analyses of Fisher's exact test, the Student's t-test or Kruskal-Wallis test were performed. Stimulated saliva cathepsin L levels in patients with ACS 12 hours but not 24 hours after admission showed significant decrease compared with that in control subjects. However, there were no significant differences in serum and unstimulated saliva cathepsin L levels between groups. Serum and saliva levels of cathepsin L remain unchanged in patients with ACS and hence may not be a promising factor in CAD risk assessment. It seems that serum and saliva cathepsin L may not be a good biomarker for CHD.

Many studies have investigated the serum BDNF levels in patients with schizophrenia. However, there are restricted data in the literature that compare the serum BDNF levels in patients with deficit and nondeficit syndromes. In this study, we aimed to compare the serum BDNF levels between schizophrenic patients with deficit or nondeficit syndrome and healthy controls.Methods: After fulfilling the inclusion and exclusion criteria, 58 patients with schizophrenia and 36 healthy controls were included in the study. The patients were grouped as deficit syndrome (N=23 and nondeficit syndrome (N=35 according to the Schedule for the Deficit Syndrome. Three groups were compared in terms of the sociodemographic and clinical variants and serum BDNF levels.Results: The groups were similar in terms of age, sex, body mass index, and smoking status. The serum BDNF levels in patients with deficit syndrome were significantly lower than those in healthy controls. In contrast, the serum BDNF levels in patients with nondeficit syndrome were similar to those in healthy controls.Conclusion: This study suggests that decreased BDNF levels may play a role in the pathophysio­logy of schizophrenic

    Objective: To explore the interrelationship among the three thyroid antibodies and their role in clinical diagnosis of thyroid auto-immune diseases by combined determination of serum TGA, TMA and TRAb in 84 patients with Hyperthyroidism. Methods; Based upon the serum concentrations of TGA and TMA, the 84 patients were divided into three groups; TGA, TMA negative group (TGA, TMA 6.84 u/L) in 60 of the 84 patients with hyperthyroidism (71.5%). For the separate groups, TRAb concentrations were positive in 42.9% of the patients of the TGA, TMA negative group, 75.0% of the TGA, TMA positive group and 85.7% of the strongly positive group. TRAb concentrations were significantly higher in patients of the strongly positive group than those in patients of the positive and negative group, but were not much different between patients of the positive and negative group. Conclusion: Positive rate of the serum TRAb increased along with the increase of positive rate of TGA and TMA. In this series of 84 thyrotoxic patients, TGA and TMA concentrations were strongly positive in 41.7% of them. It was possible that some of those strongly positive patients were of the Hashimoto type instead of Graves type

    Predicting recovery from hemiparesis after stroke is important for rehabilitation. A few recent studies reported that the levels of some growth factors shortly after stroke were positively correlated with the clinical outcomes during the chronic phase. The aim of this study was to examine the relationships between the serum levels of growth factors (vascular endothelial growth factor [VEGF], insulin-like growth factor-I [IGF-I], and hepatocyte growth factor [HGF]) and improvement in hemiparesis in stroke patients who received rehabilitation in a postacute rehabilitation hospital. Subjects were 32 stroke patients (cerebral infarction: 21 and intracerebral hemorrhage [ICH]: 11). We measured serum levels of VEGF, IGF-I, and HGF and 5 items of the Stroke Impairment Assessment Set (SIAS) for hemiparesis on admission and at discharge. Age-matched healthy subjects (n=15) served as controls. Serum levels of VEGF and HGF in cerebral infarct patients on admission were higher than those in control subjects, and the serum levels of IGF-I in stroke patients were lower than those in controls. The level of HGF in ICH patients on admission was negatively correlated with gains in SIAS, and higher outliers in HGF concentration were correlated with lower gains in SIAS. Focusing on the extremely high levels of these factors may be a predictor of the low recovery from hemiparesis after stroke. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

    Our aim was to determine whether there was a relationship between 25-hydroxyvitamin D (25[OH] D) and post-stroke depression (PSD). Two hundred and forty-four ischemic stroke patients admitted to the hospital within the first 24 h after stroke onset were consecutively recruited and followed up for 6 months. Clinical information was collected. Serum 25[OH] D levels were measured at baseline. Based on the symptoms, diagnoses of depression were made in accordance with DSM-IV criteria for depression at 6-month after stroke. At 6-month, 91 patients (37.3 %) showed depression and in 60 patients (24.6 %) this depression was classified as major. There was a significant difference in median serum 25[OH] D levels between PSD patients and no depression cases [8.3 (IQR, 6.8-9.5) vs. 15.6 (IQR, 13.2-20.3) ng/ml, respectively; P < 0.001]. Serum 25[OH] D levels ≤ 11.2 ng/ml were independently associated with PSD [odds ratio 10.32, 95 % confidence interval 4.97-28.63; P < 0.001], after adjusting for possible confounders. Serum 25[OH] D levels reduced at admission was found to be associated with PSD. Additional research is needed on vitamin D supplementation to improve the outcome of patients with PSD.

    It has been reported that skeletal muscle mass and strength are decreased in patients with heart failure (HF), and HF is associated with both reduced exercise capacity and adverse clinical outcomes. Myostatin has been known as a negative regulator of muscle growth, follistatin as the myostatin antagonist, maintaining tissue homeostasis. We thus determined serum myostatin levels in HF patients and whether they are associated with skeletal muscle wasting. Forty one consecutive HF patients (58±15years old, New York Heart Association class I-III) and 30 age-matched healthy subjects as controls (53±8years old) were studied. Serum myostatin levels were significantly lower in HF patients than controls (18.7±7.4 vs. 23.6±5.2ng/mL, Pmyostatin were significantly associated with the presence of muscle wasting. By multivariate analysis, serum myostatin levels were independently associated with muscle wasting (OR=0.77, 95% CI [0.58, 0.93], P=0.02). Serum myostatin levels were significantly decreased in HF patients and associated with lower extremity muscle wasting, suggesting that myostatin may be an important factor for maintaining skeletal muscle mass and strength in HF.

    Routine measurement of serum creatinine before injection of intravascular iodinated contrast material in all patients would be cumbersome and have an associated cost. There is doubt about whether serum creatinine should be measured routinely in all patients or selectively. The Contrast Media Safety Committee of the European Society of Urogenital Radiology decided to review the literature and draw up guidelines on this important practical issue. A literature search was carried out and summarized in a report. Based on the available information and discussions amongst the members of the Committee, guidelines were produced. The report and guidelines were discussed at the 11th European Symposium on Urogenital Radiology in Santiago de Compostela, Spain. The practice for identifying patients at risk of contrast medium induced nephropathy varies considerably from one institution to another. Patients at risk constitute only a small percentage of all cases referred for contrast enhanced imaging examination. However, it is important to identify them and take the necessary precautions. Recent serum creatinine level should be available in patients with an increased probability of a raised serum creatinine level (renal disease, renal surgery, proteinuria, diabetes mellitus, hypertension, gout, current intake of nephrotoxic drugs). A simple guideline has been produced. (orig.)

    Improved biomarkers would facilitate the diagnosis and treatment of amyotrophic lateral sclerosis (ALS). Muscle content of the neuritic outgrowth inhibitor Nogo-A is increased in patients with ALS and other denervating conditions. Seeking a less invasive diagnostic method, we sought to determine whether or not Nogo increases in the serum of ALS patients. We developed a dissociation-enhanced lanthanide fluorescent immunoassay (DELFIA) protocol to screen serum samples from 172 ALS patients and 172 healthy controls for Nogo-A immunoreactivity. Unexpectedly, there was a trend toward decreased levels of serum Nogo-A in ALS. Mean serum Nogo-A level in ALS patients was 0.71 nM (95% confidence interval (CI) 0.42-1.00), as opposed to 1.15 nM (95% CI 0.72-1.59) in healthy controls. A significantly larger percentage of healthy control sera (11.0% vs 4.7%) displayed markedly elevated levels of Nogo-A. Additional study is required to determine the factors that lead to elevated Nogo-A levels in a subset of both ALS patients and healthy controls.

    Objective: To investigate the perioperative changes of serum stress hormones cortisol and plasma angiotensin II in patients undergoing thoracotomy for malignancy. Methods: Serum cortisol and plasma angiotensin II levels were measured with RIA repeatedly in 35 thoracotomy patients operated for malignancy before operation, 1 h after starting operation, at the end of operation, and one day later, Heart rate and blood pressure were constantly monitored during operation. Results: The serum levels of cortisol and plasma angiotensin-II rose gradually during operation with significant differences among the measurements (P < 0. 001 -0.05), No age-difference for the measurements was observed except for a higher systolic pressure in patients over 60. Heart rates at 1 h were positively correlated with 1 h angiotensin-II levels. Heart rates at the end of operation were positively correlated with the cortisol and angiotensin-II levels at that time. Conclusion: The serum levels of these stress hormones rose significantly during the operation. Stress responses in older patients were adequate, yet the higher levels of stress hormones might bring more adverse effect in elderly people, especially cognition impairment. Smooth anaesthesia and adequate post-operative analgesia would lessen the stress effect, providing more ideal recovery, especially for the older patients. (authors)

    In this work, we developed a SERS platform for quantitative detection of carcinoembryonic antigen (CEA) in serum of patients with colorectal cancers. Anti-CEA-functionalized 4-mercaptobenzoic acid-labeled Au/Ag core-shell bimetallic nanoparticles were prepared first and then used to analyze CEA antigen solutions of different concentrations. A calibration curve was established in the range from 5 × 10-3 to 5 × 105 ng/mL. Finally, this new SERS probe was applied for quantitative detection of CEA in serum obtained from 26 colorectal cancer patients according to the calibration curve. The results were in good agreement with that obtained by electrochemical luminescence method, suggesting that SERS immunoassay has high sensitivity and specificity for CEA detection in serum. A detection limit of 5 pg/ml was achieved. This study demonstrated the feasibility and great potential for developing this new technology into a clinical tool for analysis of tumor markers in the blood.

    Full Text Available Objectives: Intracerebral hemorrhage (ICH is one of the most mortal subtypes of stroke. Due to the angiogenic, neurotropic, and vessel-dilating properties of basic fibroblast growth factor (bFGF in the brain, role of bFGF has been investigated in a number of neurological disorders. So far, there is only study about serum bFGF levels in patients with ICH. The first aim of the present research is to investigate whether increased serum bFGF in patients with ICH. Also, second aim was to study the association between serum levels of bFGF and clinical status in patients with ICH.Materials and methods: We measured the serum levels of bFGF in 30 patients with ICH during acute period. Age and sex matched healthy subjects (n=30 were included in controls. Serum bFGF levels were measured using an enzyme-linked immunosorbent assay method.Results: The patients with intracerebral hemorrhage had higher serum levels of bFGF when compared with the healthy controls (12.89±3.23 ng/ml, 5.28±1.75 ng/ml; p=0.001. No statistically significant difference was determined between bFGF levels of the patients who died as compared to the patients who lived (13.49±4.13 ng/ml; 12.43±3.43 ng/ml, p>0.05. No statistically significant difference was found between bFGF levels of the patients with intraventricular hemorrhage as compared to the patients without intraventricular hemorrhage (13.54±3.92 ng/ml; 12.24±2.29 ng/ml, p>0.05. There was no correlation between serum bFGF, hematoma volume, Gloskow coma scale, and National Institutes of Health stroke scale (p>0.05.Conclusion: The increased bFGF level may be one of the mechanisms that lead to angiogenesis and neuroprotection after ICH in human. .

  1. A low serum bicarbonate concentration as a risk factor for mortality in peritoneal dialysis patients.

    Directory of Open Access Journals (Sweden)

    Tae Ik Chang

    Full Text Available BACKGROUND AND AIM: Metabolic acidosis is common in patients with chronic kidney disease and is associated with increased mortality in hemodialysis patients. However, this relationship has not yet been determined in peritoneal dialysis (PD patients. METHODS: This prospective observational study included a total of 441 incident patients who started PD between January 2000 and December 2005. Using time-averaged serum bicarbonate (TA-Bic levels, we aimed to investigate whether a low serum bicarbonate concentration can predict mortality in these patients. RESULTS: Among the baseline parameters, serum bicarbonate level was positively associated with hemoglobin level and residual glomerular filtration rate (GFR, while it was negatively associated with albumin, C-reactive protein (CRP levels, peritoneal Kt/V urea, and normalized protein catabolic rate (nPCR in a multivariable linear regression analysis. During a median follow-up of 34.8 months, 149 deaths were recorded. After adjustment for age, diabetes, coronary artery disease, serum albumin, ferritin, CRP, residual GFR, peritoneal Kt/V urea, nPCR, and percentage of lean body mass, TA-Bic level was associated with a significantly decreased risk of mortality (HR per 1 mEq/L increase, 0.83; 95% CI, 0.76-0.91; p < 0.001. In addition, compared to patients with a TA-Bic level of 24-26 mEq/L, those with a TA-Bic level < 22 and between 22-24 mEq/L conferred a 13.10- and 2.13-fold increased risk of death, respectively. CONCLUSIONS: This study showed that a low serum bicarbonate concentration is an independent risk factor for mortality in PD patients. This relationship between low bicarbonate levels and adverse outcome could be related to enhanced inflammation and a more rapid loss of RRF associated with metabolic acidosis. Large randomized clinical trials to correct acidosis are warranted to confirm our findings.

    An exploratory analysis using proteomic strategies in blood serum of patients with bipolar disorder (BD), and with other psychiatric conditions such as Schizophrenia (SCZ), can provide a better understanding of this disorder, as well as their discrimination based on their proteomic profile. The proteomic profile of blood serum samples obtained from patients with BD using lithium or other drugs (N=14), healthy controls, including non-family (HCNF; N=3) and family (HCF; N=9), patients with schizophrenia (SCZ; N=23), and patients using lithium for other psychiatric conditions (OD; N=4) were compared. Four methods for simplifying the serum samples proteome were evaluated for both removing the most abundant proteins and for enriching those of lower-abundance: protein depletion with acetonitrile (ACN), dithiothreitol (DTT), sequential depletion using DTT and ACN, and protein equalization using commercial ProteoMiner® kit (PM). For proteomic evaluation, 2-D DIGE and nanoLC-MS/MS analysis were employed. PM method was the best strategy for removing proteins of high abundance. Through 2-D DIGE gel image comparison, 37 protein spots were found differentially abundant (p<0.05, Student's t-test), which exhibited ≥2.0-fold change of the average value of normalized spot intensities in the serum of SCZ, BD and OD patients compared to subject controls (HCF and HCNF). From these spots detected, 13 different proteins were identified: ApoA1, ApoE, ApoC3, ApoA4, Samp, SerpinA1, TTR, IgK, Alb, VTN, TR, C4A and C4B. Proteomic analysis allowed the discrimination of patients with BD from patients with other mental disorders, such as SCZ. The findings in this exploratory study may also contribute for better understanding the pathophysiology of these disorders and finding potential serum biomarkers for these conditions.

    A new kit for FSH determination in the serum was tested: the precision, sensitivity and specificity of this kit were adequate. With 185 men and 99 women with various hypophyseal and gonadal disorders the serum FSH was determined in radioimmunoassay as a supplement for diagnostic. Patients with hypophyseal tumors had to some extent pre-operatively increased and after hypophysectomy in general subnormal FSH values. Male patients with primary hypogonadism had without substitution therapy inclusively distinct to pronounced FSH level increases. With young patients with gynecomastia FSH values which lay primarily in the normal range were measured. Female patients with primary ovarial insufficiency often indicated very sharp increases in FSH levels. Female patients with Turner syndrome showed high FSH values at puberty age. In girls with hyposomia and hypogonadism high FSH levels refer accordingly to such a syndrome. (orig.) [de

    To explore the correlation between serum levels of Tumor Associated Materials (TAM) and clinicopathological parameters and prognosis in patients with esophageal cancer (EC). The levels of TAM were determined by chemical colorimetry in 100 EC patients and 100 healthy controls. Serum TAM levels were significantly higher in patients with esophageal carcinoma than in the control group (p TAM were associated with tumor size (p = 0.004), tumor depth (p TAM (p = 0.001). Kaplan-Meier analysis showed patients with increased levels of TAM after operation had an lower overall survival (p TAM may be an independent factor affecting the overall survival and disease-free survival (p TAM could be used to screen for tumor and assess unfavorable prognosis in patients with EC.

    We evaluated and compared serum oxidative and antioxidative parameters of patients with erectile dysfunction (ED) and control subjects. Twenty married male patients with ED for at least 12 months (Group 1) and 20 volunteer healthy, sexually active, married and age-matched men (Group 2) were included in the study. Group 1 and 2 were compared concerning serum mean total antioxidant capacity (TAC), total oxidant status (TOS), paraoxonase1 (PON1), arylesterase, total thiol and oxidative stress index (OSI). Mean patient age was 47.9 ± 8.1 and 44.4 ± 10.6, respectively, in Group 1 and 2. Serum TAC levels were 1.7 ± 0.5 and 2.3 ± 0.3, respectively, in Group 1 and 2 (P = 0.002). Serum TOS levels were 21.8 ± 20.5 and 11.7 ± 2.2, respectively, in Group 1 and 2 (P = 0.035). Serum PON1 levels were 69.8 ± 13.1 and 164.9 ± 56.5, respectively, in Group 1 and 2 (P total thiol levels were 733.1 ± 253 and 885.5 ± 95.3, respectively, in Group 1 and 2 (P = 0.016). Serum OSI was 0.14 ± 0.17 and 0.05 ± 0.11, respectively, in Group 1 and 2 (P = 0.021). Mean blood platelet count was significantly higher in Group 1 (P = 0.001). A positive correlation between platelets and oxidative state and a negative correlation between platelets and antioxidative state were found. Oxidative stress was detected to be increased, whereas antioxidative parameters were detected to be decreased in patients with ED. © 2011 Blackwell Verlag GmbH.

    Objective: To determine the concentration of C-reactive protein in pre- and post-operative serum samples of brain tumour patients in order to detect the potential risks of post-operative infections. Methods: Serum C-reactive protein was measured on pre- and post-operative Day 1, Day 2 and Day 7 in 18 patients who underwent surgery for brain tumours. The study was performed at the Neurosurgical Ward, Jinnah Postgraduate Medical Centre, Karachi, from May 2007 to April 2008. Mean pre-operative patients and control values were compared using Mann-Whitney or Wilcoxon tests for comparing between pre- and post-operative values. P-value was considered significant at 5.0mg/L but no statistically significant difference was found when compared with healthy controls, with mean 4.4+-6.6 and 0.9+-0.7, respectively. Significantly raised serum concentrations were observed in all post-operative samples when compared with pre-operative samples. Serum CRP concentrations significantly increased post-operatively on Day 1, with mean value of 102.9+-82.0mg/L (p<0.0005), and further increased on Day 2 with mean value of 166.9+-128.1mg/L (p<0.0005), but declined on Day 7, with mean value of 42.7+-63.6mg/L (p<0.005). Conclusion: Pre-operative serum C-reactive protein concentrations of 28% of the patients were elevated, suggesting an association with brain tumours. Post-operative serum concentrations were significantly higher than those noted before the surgery. Absence of a fall of concentration from peak value on post-operative Day 2 or a secondary rise from post-operative Day 7 could be alarming for inter-current infection. (author)

    Objective: To study the effects of low-flux hemodialysis (LFHD), high-flux hemodialysis (HFHD) and hemodiafiltration (HDF) on the serum inflammatory cytokine in maintenance hemodialysis (MHD) patients. Methods: Sixty MHD patients were randomly divided into LFHD group, HFHD group and HDF group. Results: The levels of serum CRP, IL-6, IL-8 and TNF-α were detected in three groups and control group. The results showed that levels of CRP, IL-6, IL-8 and TNF-α in patients with MHD before treatment were much higher than these in control group (P 0.05). The levels of CRP, IL-6, IL-8 and TNF-α did not significantly decrease in patients with HFHD after the first hemodialysis (P>0.05). The levels of CRP, IL-6, IL-8 and TNF-α decreased markedly in patients with HFHD after 6 months hemodialysis (P<0.05). The levels of CRP, IL-6, IL-8 and TNF-α decreased significantly in patients with HDF after the first hemodialysis and after 6 months (P<0.05). The levels of CRP, IL-6, IL-8 and TNF-α in HDF group were significantly lower than those in HFHD group after 6 months (P<0.05). Conclusion: There was microinflammatory state in MHD patients. The lowering of patients' serum CRP, IL-6, IL-8 and TNF-α levels and thus the recovery from microinflammatory state may be achieved by HDF, HFHD, and HFHD preferably by HDF. (authors)

    Total blood homocysteine (Hcys) and folate levels have been investigated in association with cognitive dysfunction in healthy but not in multimorbid elderly patients. We hypothesized that total serum Hcys is an adequate marker to identify multimorbid elderly patients with cognitive dysfunction assessed by the Short Cognitive Performance Test (SKT) and Mini-Mental State Examination (MMSE). Cross-sectional study. The study center was an acute geriatric hospital. A total of 189 multimorbid elderly patients were recruited. Cognitive dysfunction was determined according to the SKT and MMSE. Biochemical parameters (Hcys, folate, vitamin B12, hemoglobin), nutritional status (BMI, Mini Nutritional Assessment, nutritional intake), and activities of daily living were assessed. According to the SKT, 25.4% of patients showed no cerebral cognitive dysfunction, 21.2% had suspected incipient cognitive dysfunction, 12.7% showed mild cognitive dysfunction, 9.0% had moderate cognitive dysfunction, and 31.7% of patients were demented. The median plasma Hcys value was elevated by approximately 20% in multimorbid elderly patients, independent of cognitive dysfunction. Serum folate and vitamin B12 concentrations were within normal ranges. We did not find significant differences in nutritional status, activities of daily living, numbers of diseases or medications, or selected biochemical parameters between the SKT groups. Elevated serum Hcys levels with normal plasma folate and vitamin B12 concentrations were observed in multimorbid elderly patients. The plasma Hcys level did not appear to be an important biological risk factor for cognitive dysfunction in multimorbid geriatric patients.

    Full Text Available With the increasing importance of early type 2 diabetes (DM2 and obesity detection, it is useful to reevaluate leptin role in these conditions. Our study aimed at investigating circulating leptin concentrations in a group of patients with DM2, and at assessing in detail whether leptin concentrations correlate with selected biochemical, clinical parameters and markers of systemic inflammation in patients with DM2 and in healthy volunteers. In our work, we analysed samples and data drawn from 71 patients aged 61.4 ± 11.7 years, who have been diagnosed with type 2 diabetes, as well as from a healthy control group (HC consisting of 51 healthy subjects with a mean age of 57.8 ± 13.7 years. Therein, the concentration of leptin in the DM2 patients was significantly higher than in the HC (p < 0.01, with median value of 16.59 (IQR 8.58-33.39 ng/ml in the DM2, vs median value of 6.66 (IQR 4.52-21.40 ng/ml in the HC. In the analysis of variance, higher leptin concentrations were revealed in the DM2 group as compared to the HC, and this figure remained significant after adjusting for gender and age (p < 0.001. Moreover, it was independent of HOMA-IR (p = 0.003. However, the differences in leptin levels between the groups disappeared when additional adjustments for anthropometric parameters (BMI, waist circumference were applied (p = 0.088. Beyond the aforementioned, significant positive correlations were found in the DM 2 group between leptin level and CRP (r=0.256; p < 0.05 and IL-6 (r = 0.345; p < 0.01. Among the selected variables, only gender and BMI were included in the predictive model explaining the variability of leptin, and, in total, were responsible for 72.6% of the original variation of the studied adipocytokine. The results of this study have led to conclusion that leptin may participate in the complex pathogenesis of DM2 and be a predictor of the development of this disease. As higher concentrations of leptin coexist with obesity, and this

    Various microRNAs from the miR-371-3 and miR-302a-d clusters have recently been proposed as markers for testicular germ cell tumours. Upregulation of these miRNAs has been found in both the tissue and serum of testicular cancer patients, but they have never been studied in human seminal plasma. The aim of this study was, therefore, to assess the differences in the expression of miR-371-3 and miR-302a-d between the seminal plasma and serum of testicular cancer patients, and to identify new potential testicular cancer markers in seminal plasma. We investigated the serum and seminal plasma of 28 pre-orchiectomy patients subsequently diagnosed with testicular cancer, the seminal plasma of another 20 patients 30 days post-orchiectomy and a control group consisting of 28 cancer-free subjects attending our centre for an andrological check-up. Serum microRNA expression was analysed using RT-qPCR. TaqMan Array Card 3.0 platform was used for microRNA profiling in the seminal plasma of cancer patients. Results for both miR-371-3 and the miR-302 cluster in the serum of testicular cancer patients were in line with literature reports, while miR-371and miR-372 expression in seminal plasma showed the opposite trend to serum. On array analysis, 37 miRNAs were differentially expressed in the seminal plasma of cancer patients, and the upregulated miR-142 and the downregulated miR-34b were validated using RT-qPCR. Our study investigated the expression of miRNAs in the seminal plasma of patients with testicular cancer for the first time. Unlike in serum, miR-371-3 cannot be considered as markers in seminal plasma, whereas miR-142 levels in seminal plasma may be a potential marker for testicular cancer.

    Full Text Available Background and Design: It has been known that isotretinoin may cause rabdomyolysis besides its many side affects. The purpose of our study was to evaluate the effect of isotretinoin therapy with a cumulative dose of 120 mg/kg on serum creatine phosphokinase levels and muscle physiology in patients with acne vulgaris.MATERIAL-METHOD: A total of 66 patients with severe acne vulgaris were enrolled in the study and treated with isotretinoin twice daily at the dose of 0.6-0.8 mg/kg/day and for approximately 6.1±0.54 (3-7 months. Thirty-seven female (71.2% and 15 male (28.8% patients completed the study. The change in serum creatine kinase levels was measured before and monthly during the treatment course. Electromyography was performed in patients with a high serum CPK level and myalgia for the exclusion myopathy. All patients were evaluated with their laboratory findings and they were questioned for exercise habits and intramuscular injections.RESULTS: The mean age and body weight was 24.6±6.1 years and 62.3±11.9 kg respectively. We have detected 7 patients having elevated (13.5% serum CPK levels. Three of them had associating myalgia and muscle tenderness. The evaluation of these patients with EMG revealed no myopathy sign. (CPK values =1000, 880,726 respectively Only one patient with an elevated serum CPK was performing exercise. There was no history of intramuscular injection history in any of these patients. CONCLUSION: The use of standard isotretinoin therapy appears to have a relation with marked hyperCKemia with or without muscle-related complaints. Isotretinoin could have a potentializing effect on other myotoxicity inducers (drugs, infection, fever, muscular exertion. Although this phenomenon in isotretinoin-treated patients with acne appears to be validated as benign in nature, the clinicians must keep this side affect in mind and should monitorize serum CPK levels since there are some patients who had severe or persistent signs.

    Background It is still unknown whether increased cardiac adiposity is related to the risk factors of coronary artery disease (CAD). We measured epicaridal adopose tissue (EAT) and mediastinal adipose tissue (MAT) using echocardiography and examined their correlations with CAD and serum adiponectin. Methods One hundred fifty three patients who underwent elective coronary angiography for chest pain were measured cardiac adiposity by transthoracic echocardiography. The correlations of cardiac adipose tissue with the presence and severity of CAD and the serum adiponectin level were examined. Results EAT was thicker in patients with CAD (1.8±1.4 vs. 3.8±1.9 mm, phomocystein (r=0.289, p=0.001), fasting glucose (r=0.167, p=0.042), and fibrinogen (r=0.218, p=0.009), and a significant negative correlation with serum adiponectin (r=-0.194, p=0.016). EAT thickness (OR 11.53, 95% CI; 3.61-36.84, p<0.001) and low serum adiponectin (OR 2.88, 95% CI; 1.02-8.15, p=0.046) were independent predictors of obstructive CAD. However, MAT thickness was not associated with CAD. Conclusion EAT was associated with the severity and risk factors of CAD and correlated with serum adiponectin level. In contrast with EAT, MAT was not associated with CAD and adiponectin. PMID:20661336

    Obesity and insulin resistance are associated with classic and new cardiovascular risk factors, such as inflammatory markers and adipocytokines. The aim of this study was to examine whether weight reduction could change visfatin serum concentrations in obese patients. This was an interventional longitudinal study analyzing a population of 80 obese non-diabetic outpatients. Weight, blood pressure, fasting serum glucose, C-reactive protein, plasma insulin, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triacylglycerols, and insulin resistance (homeostatic model assessment) were measured before and after 3 mo on a hypocaloric diet. Eighty patients were enrolled. The mean age was 46.7 +/- 16.7 y, the mean body mass index was 34.1 +/- 4.8 kg/m(2), with 20 men (25%) and 60 women (75%). After 3 mo on a hypocaloric diet, body mass index, fat mass, waist circumference, systolic blood pressure, fasting serum glucose, total cholesterol, and low-density lipoprotein cholesterol decreased. The serum concentration of visfatin decreased with weight loss (112.14 +/- 70.2 versus 99.4 +/- 58.1 ng/mL, P hypocaloric diet is associated with a significant decrease in circulating serum concentrations of the novel adipokine visfatin in obese subjects. Visfatin is inversely correlated with age.

    A connection between dementias and blood-brain barrier (BBB) dysfunction has been suggested, but previous studies have yielded conflicting results. We examined cerebrospinal fluid (CSF)/serum albumin ratio in a large cohort of patients diagnosed with Alzheimer's disease (AD, early onset [EAD, n = 130], late onset AD [LAD, n = 666]), vascular dementia (VaD, n = 255), mixed AD and VaD (MIX, n = 362), Lewy body dementia (DLB, n = 50), frontotemporal dementia (FTD, n = 56), Parkinson's disease dementia (PDD, n = 23), other dementias (other, n = 48), and dementia not otherwise specified (NOS, n = 271). We compared CSF/serum albumin ratio to 2 healthy control groups (n = 292, n = 20), between dementia diagnoses, and tested biomarker associations. Patients in DLB, LAD, VaD, MIX, other, and NOS groups had higher CSF/serum albumin ratio than controls. CSF/serum albumin ratio correlated with CSF neurofilament light in LAD, MIX, VaD, and other groups but not with AD biomarkers. Our data show that BBB leakage is common in dementias. The lack of association between CSF/serum albumin ratio and AD biomarkers suggests that BBB dysfunction is not inherent to AD but might represent concomitant cerebrovascular pathology.

    Full Text Available Abstract Background Cancer serum protein profiling by mass spectrometry has uncovered mass profiles that are potentially diagnostic for several common types of cancer. However, direct mass spectrometric profiling has a limited dynamic range and difficulties in providing the identification of the distinctive proteins. We hypothesized that distinctive profiles may result from the differential expression of relatively abundant serum proteins associated with the host response. Methods Eighty-four antibodies, targeting a wide range of serum proteins, were spotted onto nitrocellulose-coated microscope slides. The abundances of the corresponding proteins were measured in 80 serum samples, from 24 newly diagnosed subjects with lung cancer, 24 healthy controls, and 32 subjects with chronic obstructive pulmonary disease (COPD. Two-color rolling-circle amplification was used to measure protein abundance. Results Seven of the 84 antibodies gave a significant difference (p Conclusion Our results suggest that a distinctive serum protein profile involving abundant proteins may be observed in lung cancer patients relative to healthy subjects or patients with chronic disease and may have utility as part of strategies for detecting lung cancer.

    Full Text Available Diabetes has been associated with periodontitis, but the mechanisms through which periodontal diseases affect the metabolic control remain unclear. Objective: This study aimed to evaluate serum leveis of inflammatory markers, IL-8, IL-6 and monocyte chemoattractant protein 1 (MCP-1, in type 2 diabetic patients in the presence of chronic periodontitis. Material and Methods: Forty two individuals were enrolled in this study and assigned to one of five groups: diabetes mellitus with inadequate glycemic control and periodontitis (DMI+P, n = 10, diabetes mellitus with adequate glycemic control and periodontitis (DMA+P, n = 10, diabetes mellitus without periodontitis (DM, n = 10, periodontitis without diabetes (P, n=6, and neither diabetes nor periodontitis (H, n = 6. Periodontal clinical examination included visible plaque index (PL, gingival bleeding index (GB, probing depth (PD, attachment level (AL and bleeding on probing (BP. Glycemic control was evaluated by serum concentration of glycated hemoglobin (HbAlc. Inflammatory serum markers IL-8, IL-6 and (MCP-1 were measured by ELISA. Results: DMI+P and DMA+P groups presented higher PD (p=0.025 and AL (p=0.003 values when compared to the P group. There were no significant differences among groups for IL-6, IL-8 and MCP-1 serum levels. Conclusions: Although periodontitis was more severe in diabetic patients, the serum levels of the investigated inflammatory markers did not differ among the groups.

    Objective: To explore the value of serum thyrotrophin receptor antibody (TRAb) on the pathological mechanism of Graves ophthalmopathy. Methods: Two hundred and nineteen newly diagnosed Graves disease patients who were divided into Graves ophthalmopathy group (n=121) and without Graves ophthalmopathy group (n=98) were tested serum concentration with thyroid function, thyroperoxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and TRAb. According to the consensus statement of the European Group on Graves ophthalmopathy, clinical activity score (CAS) and severity evaluation were carried out on Graves ophthalmopathy patients. Results: There was no significant difference in serum concentration of free thyroxine (FT 4 ), free triiodothyronine (FT 3 ), TPOAb and TRAb between the Graves ophthalmopathy group and the without Graves ophthalmopathy group. Serum concentration of TRAb was not correlated with the severity and CAS of Graves ophthalmopathy. Conclusions: The CAS and the severity of Graves ophthalmopathy were irrelevant to the serum concentration of TRAb. Therefore, the correlation between TRAb and Graves ophthalmopathy still needs further study. (authors)

    Objectives: The aim of this study was to evaluate liver function in patients with type 2 diabetes mellitus (T2DM) with and without metabolic syndrome (MS) by determining serum levels of gamma glutamyltransferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). We also investigated correlation between levels of liver enzymes and some components of MS in both groups of patients. Methods: This cross-sectional study included 96 patients (age 47–83 years) with T2DM. All patients were divided according to the criteria of the National Cholesterol Education Program (NCEP) in two groups: 50 patients with T2 DM and MS (T2DM-MS) and 46 patients with T2DM without MS (T2DM-Non MS). The analysis included blood pressure monitoring and laboratory tests: fasting blood glucose (FBG), total lipoprotein cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), fibrinogen and liver enzymes: GGT, ALT and AST. T2DM-MS group included patients which had FBG ≥ 6,1 mmol/L, TG ≥ 1,7 mmol/L and blood pressure ≥ 130/85 mm Hg. Results: T2DM-MS patients had significant higher values of systolic blood pressure, diastolic blood pressure and medium arterial pressure compared to T2DM-Non MS patients. Serum levels of TC, TG, LDL-C, VLDL-C and FBG were significantly higher in the T2DM-MS group compared to the T2DM-Non MS group. Serum fibrinogen level and GGT level were significantly higher in patients with T2DM-MS compared to the serum fibrinogen level and GGT level in T2DM-Non MS patients. Mean serum AST and ALT level were higher, but not significantly, in patients with T2DM and MS compared to the patients with T2DM without MS. Significant negative correlations were observed between TC and AST (r= -0,28, p<0,05), as well as between TC and ALT level (r= -0,29, p<0,05) in T2DM-MS group of patients. Conclusion: These results suggest that patients with T2DM and MS have markedly elevated liver enzymes. T2DM and MS probably play a role in

    Full Text Available Tryptophan (Trp is present in the serum, partly bound to albumine and in the free form. The unbound portion of circulating tryptophan has the property of crossing the hematoencephalic barrier and being converted within the brain into serotonin (5-HT through the enzymatic processes of hydroxylation and decarboxylation. The serotoninergic system plays an important role in neuroendocrine control of reproductive hormone secretion, and in particular, it may influence GnRH pulsatility, a function essential for reproductive processes. In this study, we analysed serum levels of tryptophan, serotonin and 5-hydroxytryptophan (5-HTP in women with three different forms of amenorrhea: 16 patients were diagnosed with anorexia nervosa, 60 patients with functional hypothalamic amenorrhea, and 14 patients with hyperprolactinemia. Data were compared with those of a group of 25 healthy women. Serum Trp levels were significantly (P ≤ 0.05 lower in the anorexic (11.64 ± 0.53 μg/ml, mean ± S.E. than in the control (12.98 ± 0.37 μg/ml groups. In addition, in the anorexic group a statistical dispersion of Trp values was shown indicating a bimodal data distribution suggesting the existence of two different subgroups of patients. Regarding 5-HTP, an increase of its serum level was observed in all the groups with amenorrhea with the highest value in hyperprolactinemic patients. On the contrary, no statistical differences in serum 5-HT levels among the four analyzed groups were observed. This study shows that women affected by various forms of amenorrhea present an altered metabolism of tryptophan via serotonin and, in particular, markedly high differences are observed between the two subgroups of anorexic patients.

    Alopecia areata is an immune-dependent disorder characterized by the interaction of T-lymphocytes with follicular antigens. Recent studies have shown the existence of a local renin-angiotensin system in the skin, where angiotensin-converting enzyme (ACE) plays a role in autoimmunity and inflammation. The objective of this study was to evaluate serum and tissue ACE activity in patients with alopecia areata. This case-control study was conducted on patients with alopecia areata and healthy controls. Serum and tissue ACE activity were assessed and compared between the two groups. Twenty-five alopecia areata patients (60% male, mean age 32.1 ± 9.9 years) and 24 controls (50% male, mean age 37.4 ± 8.8 years) were included. Mean serum ACE activity was 52.1 ± 9 U/L in cases and 55.3 ± 14.7 U/L in controls (P = 0.37). Tissue ACE activity was significantly lower in cases in all parts of the skin i.e. epidermis (P = 0.016), follicular epithelium (P = 0.004), and endothelium (P = 0.037). Among cases, serum ACE activity was significantly higher in patients with more severe disease (P = 0.030), nonpatchy alopecia areata (alopecia universalis; ophiasis, patchy and ophiasis, diffuse) (P = 0.029), and with nail involvement (P = 0.027). The sample size was too small to draw definite conclusions. Further, most of the patients had only mild or moderate alopecia areata. Unlike in some other inflammatory diseases, the tissue level of ACE seems to be significantly lower in alopecia areata compared to normal controls. Serum ACE was significantly higher in patients with more severe disease.

    Chronic liver disease is characterized by numerous metabolic alterations resulting in the clinical picture of malnutrition or even cachexia and contributing to complications such as hepatic encephalopathy and ascites. Leptin is a hormone that plays an important role in regulating energy intake and expenditure including appetite and metabolism. Interleukin-6 (IL-6), on the other hand, is generally considered to be one of the important cytokines that regulate immunologic and metabolic actions. The aim of the present study was to investigate serum leptin and IL-6 levels in liver cirrhosis, as well as to determine their levels in relation to liver functions and lipid profile. This study was conducted on 25 patients with post- viral hepatic cirrhosis compared to 20 healthy matched individuals served as controls with the same age and sex. The severity of the disease assessed with Child-Pugh criteria yielded 8 patients (3 women, 5 men) with stage A, 10 patients (4 women, 6 men) with stage B and 7 patients (2 women, 5 men) with stage C. Compared to controls, body mass index (BMI) was decreased and reached statistical significance in group C liver cirrhosis (P< 0.05). Also, serum leptin level was highly significantly decreased in the three groups, while IL-6 level showed highly significant increase. Leptin level negatively correlated with aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin and positively correlated with serum albumin, triglycerides (TG), cholesterol and low density lipoprotein (LDL). In contrast, serum IL-6 level positively correlated with parameters of liver functions and negatively correlated with parameters of lipid profile. Additionally, there was highly significant negative correlation between serum leptin and IL-6 levels (P < 0.001) in post-hepatic cirrhotic patients. We concluded that leptin and IL-6 have important role in diagnosis and prognosis of patients with post-hepatic liver cirrhosis

    Oxidative stress and low antioxidant status play a major role in the pathogenesis of inflammatory and autoimmune diseases. Myasthenia gravis (MG) is an autoimmune condition targeting the neuromuscular junction, and its antioxidant status is still controversial. Our study aimed to investigate the correlation between the clinical characteristics of MG and the serum antioxidant status of bilirubin (Tbil, Dbil and Ibil), uric acid, albumin and creatinine. We measured serum antioxidant molecule levels of bilirubin (Tbil, Dbil and Ibil), uric acid, albumin and creatinine in 380 individuals, including 166 MG and 214 healthy controls. We found that MG patients had significantly lower serum levels of bilirubin (Tbil, Dbil and Ibil), uric acid, albumin and creatinine than healthy controls, whether male or female. Moreover, it was also shown in our study that uric acid, albumin and creatinine levels in patients with MG were correlated with disease activity and classifications performed by the Myasthenia Gravis Foundation of America. Our findings demonstrated that serum levels of bilirubin (Tbil, Dbil and Ibil), uric acid, albumin and creatinine were reduced in patients with MG. This suggested an active oxidative process in MG patients who had low antioxidant status.

    The aim of this study was to investigate the effects of ginger supplementation on serum glucose, advanced glycation end products, oxidative stress, and systemic and vascular inflammatory markers in patients on peritoneal dialysis (PD). In this randomized, double-blind, placebo-controlled trial, 36 patients on PD were randomly assigned to either the ginger or the placebo group. The patients in the ginger group received 1000 mg/d ginger for 10 wk, whereas the placebo group received corresponding placebos. At baseline and the end of week 10, serum concentrations of glucose, carboxymethyl lysine, pentosidine, malondialdehyde (MDA), high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), and sE-selectin were measured after a 12- to 14-h fast. Serum fasting glucose decreased significantly up to 20% in the ginger group at the end of week 10 compared with baseline (P ginger reduces serum fasting glucose, which is a risk factor for hyperinsulinemia, dyslipidemia, peritoneal membrane fibrosis, and cardiovascular disease, in patients on PD.

    Objective: To investigate the clinical value of peri-interventional procedure serum bile acid (TBA) detection in patients with primary liver cancer. Methods: The serum TBA was examined peri-operatively in 160 patients with primary liver cancer for testing the correlations between TBA, liver function, the degree of hepatocirrhosis, interventional therapy method and hepatic failure. Results: The preoperative mean value of serum TBA increased significantly in comparing with that of the control group (P<0.01). The preoperative value of serum TBA in different Child grading patients with primary liver cancer were different significantly (P<0.01), Child A< Child B< Child C, the increased degree of serum TBA corresponded with Child grading of the liver function and the cirrhotic degree of liver. In patients with liver function of Child B and C, the postoperative mean values of serum TBA in different interventional therapy methods were different significantly (P<0.01). Comparing with that of the patients without hepatic failure, the postoperative value of serum TBA in the patients with hepatic failure increased significantly (P<0.01). Conclusions: The value of serum TBA can sensitively and accurately reflect liver reserve ability and damage degree of peri-interventional procedure liver function.

    Full Text Available Background: Uric acid is an independent risk factor for cardiovascular disease. Hospital admission for ischemic heart disease (IHD is increasing rapidly in our country. Although studies were conducted abroad regarding association of serum uric acid with in-hospital outcomes in patients with acute coronary syndrome (ACS, no data is yet available to show the association in our country. Objective: The objective of this study was to assess the association of serum uric acid level on admission with in-hospital outcomes of the patients with ACS. Materials and Methods: This cross sectional comparative study was done in the Department of Cardiology, Dhaka Medical College Hospital (DMCH from January to December 2012. After proper ethical consideration total 93 ACS patients were enrolled in the study by nonrandom sampling. Serum uric acid of all subjects was measured within 24 hours of admission. Then in-hospital outcomes were observed in all subjects. Results: The frequency of hyperuricemia among ACS patients was 24.7% (22.54% in male and 31.82% in female. Hyperuricemic patients significantly developed heart failure (30.4% vs 11.4%, p=0.032 and conduction defect (13.0% vs 1.4%, p=0.017 than normouricemic subjects. The mean ejection fraction was significantly lower in hyperuricemic patients than patients with normal uric acid level (50.87 ± 10.27% vs 55.94 ± 6.66%. The mean ± SD duration of hospital stay of hyperuricemic group was significantly longer in patients with ACS (8.26 ± 1.18 vs 7.51±1.18 days, p=0.010. Conclusion: The measurement of serum uric acid level, an easily available and inexpensive biochemical tool, might turn out as a valuable risk marker for prediction of in-hospital outcomes in patients with ACS.

    Background. Early diagnosis and treatment are crucial in invasive fungal diseases (IFD). Serum (1-3)-β-d-glucan (BG) is believed to be an early IFD marker, but its diagnostic performance has been ambiguous, with insufficient data regarding sensitivity at the time of IFD diagnosis (TOD) and according to outcome. Whether its clinical utility is equivalent for all types of IFD remains unknown. Methods. We included 143 patients with proven or probable IFD (49 invasive candidiasis, 45 invasive aspergillosis [IA], and 49 rare IFD) and analyzed serum BG (Fungitell) at TOD and during treatment. Results. (1-3)-β-d-glucan was undetectable at TOD in 36% and 48% of patients with candidemia and IA, respectively; there was no correlation between negative BG results at TOD and patients' characteristics, localization of infection, or prior antifungal use. Nevertheless, patients with candidemia due to Candida albicans were more likely to test positive for BG at TOD (odds ratio = 25.4, P = .01) than patients infected with other Candida species. In 70% of the patients with a follow-up, BG negativation occurred in >1 month for candidemia and >3 months for IA. A slower BG decrease in patients with candidemia was associated with deep-seated localizations (P = .04). Thirty-nine percent of patients with rare IFD had undetectable BG at TOD; nonetheless, all patients with chronic subcutaneous IFD tested positive at TOD. Conclusions. Undetectable serum BG does not rule out an early IFD, when the clinical suspicion is high. After IFD diagnostic, kinetics of serum BG are difficult to relate to clinical outcome.

    Soluble progranulin (PGRN) is known to directly regulate regulatory T cells; however, whether PGRN levels are elevated in patients with rheumatoid arthritis and affect the regulatory subsets of B cells remain unknown. In this study, a total of 80 RA patients and 60 healthy controls were studied. Serum progranulin levels were determined using enzyme-linked immune-sorbent assay. A receiver operating characteristic (ROC) curve was used to evaluate the feasibility of serum PGRN as a biomarker for distinguishing patients with RA. CD19(+)CD5(+)GrB(+) B cells were analyzed by flow cytometry in peripheral blood mononuclear cells (PBMCs). Serum progranulin levels in RA patients (median, 59.4 ng/mL) and in RA patients DAS28 > 5.1 (median, 71.98 ng/mL) were much higher than those in normal controls (median, 46.3 ng/mL; P progranulin levels was 0.705 for RA versus normal controls and the area under the ROC curve for progranulin levels in RA patients DAS28 > 5.1 was 0.977 versus normal controls (P progranulin and DAS28, CRP, ESR were all positively correlated in RA patients (P 0.05). Our findings indicated that induction of PGRN expression may play a role in RA immune reaction and PGRN levels could be a useful biomarker in RA inflammatory response, but irrelated with Breg cell levels.

    Objective: To study the changes of serum contents of gastrin in patients with various benign and malignant gastric diseases. Methods: Serum contents of gastrin were determined with RIA in 40 patients with chronic superficial gastritis, 42 patients with gastric ulcer, 39 patients with gastric carcinoma and 38 controls. Results: Serum contents of gastrin in patients with chronic superficial gastritis (96.99 ± 19.80ng/L), gastric ulcer (99.61 ± 26.39ng/L) and gastric cancer (128.58 ± 21.39ng/L) were all significantly higher than those in controls (81.96 ± 13.67ng/L) (P<0.01). The contents in patients with gastric cancer were the highest and were significantly higher than those in both of the other two groups of patients (both P<0.01). Conclusion: Gastric cancer could express gastrin as an autocrine product, which in turn enhance the tumor proliferation of gastric adenocarcinoma cells. (authors)

    Objective: To study the correlationship between the serum aldosterone levels and different stages of chronic renal insufficiency. Methods: Plasma renin activity (PRA), serum angiotensin II (Ang II) contents and serum aldosterone concentration (SACs) were determined with RIA in 42 patients with chronic renal insufficiency from various causes. The patients were divided into three groups according to their endogenous creatinine clearance rate: Group 1, (n=14) Ccr≥60ml/(min·1.73m 2 ); Group 2, (n =13) 20ml/(min·1.73m 2 ) ≤Ccr 2 ); Group 3, (n=15) Ccr 2 ). Results: The SACs values in Group 3 patients were significantly higher than those in Group 1 and Group 2 patients (P<0.01). The SACs values in Group 2 patients were also significantly higher than those in Group 1 patients (P<0.05). Ccr values were higher negatively correlated with the SACs values (r= -0.685, P<0.001). Conclusion: As the creatine clearance rate gradually deteriorated, the SACs values increased correspondingly in patients with chronic renal insufficiency from various causes. (authors)

    The purpose of the study is to determine the influence of serum thiamine, glutathione peroxidase (GPx) activity, and serum protein carbonyl concentrations in hospital mortality in patients with septic shock. This prospective study included all patients with septic shock on admission or during intensive care unit (ICU) stay, older than 18 years, admitted to 1 of the 3 ICUs of the Botucatu Medical School, from January to August 2012. Demographic information, clinical evaluation, and blood sample were taken within the first 72 hours of the patient's admission or within 72 hours after septic shock diagnosis for serum thiamine, GPx activity, and protein carbonyl determination. One hundred eight consecutive patients were evaluated. The mean age was 57.5 ± 16.0 years, 63% were male, 54.6% died in the ICU, and 71.3% had thiamine deficiency. Thiamine was not associated with oxidative stress. Neither vitamin B1 levels nor the GPx activity was associated with outcomes in these patients. However, protein carbonyl concentration was associated with increased mortality. In patients with septic shock, oxidative stress was associated with mortality. On the other hand, thiamine was not associated with oxidative stress or mortality in these patients. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Interferon beta is a safe and efficacious treatment for relapsing multiple sclerosis (MS. However, there is some evidence that uric acid, a scavenger of peroxynitrite, is involved in MS pathology and that increasing serum uric acid levels might have beneficial therapeutic effects. The aim of this study is to investigate serum uric acid levels in MS patients before and after long-term interferon beta treatment. Blood samples from 101 MS patients (53 receiving interferon beta 1a treatment and 48 receiving interferon beta 1b treatment; 28 male and 73 female; mean age at treatment onset 32,4±7,3 years; mean duration of disease at treatment onset 5,1±3,2 years; mean EDSS 2±1,3 before and after interferon beta treatment (mean treatment duration 3±2 years were analysed. Serum uric acid levels were measured using a quantitative enzymatic assay (Elitech Diagnostic, Sees, France. MS patients had significantly increased serum uric acid levels after treatment compared with those at the beginning of treatment (272,31±78,21 μmol/l vs. 210,17±53,65 μmol/l; p=0,019, Wilcoxon Mann-Whitney U-test. We did not find significant differences in serum uric acid levels between the interferon beta 1a and interferon beta 1b groups (p=0.98. These results indicate that one of the beneficial effects of interferon beta in MS might be based on the elevation of serum uric acid levels as a natural scavenger of peroxynitrite.

    Background Proglucagon-derived hormones represent a family of peptides mainly produced in the pancreas and the intestine. While several proglucagon-derived peptides play key roles in metabolic diseases, little is known about glicentin. The aim of the present study was to investigate serum glicentin concentrations in individuals with adult obesity and to study its potential link with various metabolic parameters. Methods Fifty-two individuals with normal body mass index (BMI  35 kg/m 2 ) were prospectively included at the University Hospital of Nice between January 2014 and April 2016. Clinical data were recorded, and a fasting blood sample was collected to measure glicentin, glucose, insulin, C-peptide, total cholesterol, triglyceride, LDL and HDL-cholesterol. In addition, a homeostasis model assessment for insulin resistance (HOMA2-IR) was also calculated. Results Patients with severe and morbid obesity had significantly higher plasma glucose, together with higher serum concentrations of insulin, C-peptide, HOMA2-IR, triglyceride, LDL-cholesterol and lower serum concentrations of HDL-cholesterol compared with individuals with a normal body mass index. The obese patients displayed significantly lower fasting serum concentrations of glicentin compared with subjects with a normal body mass index (12 pmol/L vs. 24 pmol/L, P < 0.0001). In the total population, fasting glicentin concentrations did not correlate with BMI, glycaemic parameters (glucose, insulin, C-peptide, HOMA-IR) or lipid parameters (total cholesterol, triglyceride, LDL and HDL-cholesterol). Conclusion To the best of our knowledge, this is the first study reporting serum glicentin concentrations in healthy lean and obese adult subjects. We found that fasting serum glicentin concentrations are decreased in patients with severe or morbid obesity suggesting the potential interest of this peptide in obesity and metabolic-related disorders.

    Cervical radiation therapy is often applied to patients with head and neck cancers because radiation has a high sensitivity to these cancers and permits the preservation of functions and physical form. However, it has been shown that various complications can result from radiation therapy. We have encountered some patients who showed hypercholesterolemia resulting from cervical radiation. Therefore, we have paid close attention to the relationship between hypercholesterolemia after cervical radiation and hypothyroidism. Thyroid hormone tests in these patients with hypercholesterolemia after cervical radiation showed high thyroid stimulating hormone (TSH) and low free thyroxine (fT 4 ), indicating the presence of hypothyroidism. After administration of levothyroxine Na, their fT 4 levels increased and both TSH levels and serum total cholesterol levels decreased. In conclusion, in patients who have received cervical radiation, we recommend monitoring serum total cholesterol periodically to detect hypothyroidism easily before the appearance of its symptoms.

However, it has been shown that various complications can result from radiation therapy. We have encountered some patients who showed hypercholesterolemia resulting from cervical radiation. Therefore, we have paid close attention to the relationship between hypercholesterolemia after cervical radiation and hypothyroidism. Thyroid hormone tests in these patients with hypercholesterolemia after cervical radiation showed high thyroid stimulating hormone (TSH) and low free thyroxine (fT{sub 4}), indicating the presence of hypothyroidism. After administration of levothyroxine Na, their fT{sub 4} levels increased and both TSH levels and serum total cholesterol levels decreased. In conclusion, in patients who have received cervical radiation, we recommend monitoring serum total cholesterol periodically to detect hypothyroidism easily before the appearance of its symptoms.

    2004-01-01

    Objective: To evaluate the relationship between serum levels of leptin and microangiopathy in patients with type 2 diabetes. Methods: Fasting serum leptin (with RIA), insulin (with RIA) and fasting blood glucose (with oxidase method) levels were measured in 30 controls, 30 diabetic patients without microangiopathy and 30 patients with diabetic microangiopathy. Correlations between levels of serum leptin and other parameters were analyzed. Results: The levels of serum leptin in controls, diabetic patients without microangiopathy and patients with diabetic microangiopathy were (7.20 ± 2.11) μg/L, (7.95 ± 3.78) μg/L and (19.26 ± 4.37) μg/L respectively. The patients with diabetic microangiopathy had higher serum leptin levels than those in the diabetic patients without microangiopathy (t=2.18, P<0.05) and controls (t = 2.71, P<0.01), while the serum leptin levels in diabetic patients without microangiopathy were not significantly different from those in controls. The serum leptin levels were positively correlated with BMI and FINS (r=0.29, P<0.05; r=0.34, P<0.01). Conclusion: Serum leptin levels were elevated in patients with diabetic microangiopathy and were closely related with the development of diabetic microangiopathy. (authors)

    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.

    Full Text Available Background: Rheumatoid arthritis (RA is a chronic progressive autoimmune disorder characterized by symmetric erosive synovitis and sometimes shows multisystem involvement. The long-term outcome of the disease is characterized by significant morbidity and increased mortality. Elevated free radical generations in inflamed joints and impaired antioxidant system have been implicated in RA. Nitric oxide (NO can also induce tissue damage, especially after conversion into peroxynitrite radical (ONOO·. Aims: To estimate the serum levels of MDA, Nitric Oxide (NO and Vitamin E in patients with Rheumatoid Arthritis. Materials and Methods: The study includes 50 RA patients who were fulfilling the American Rheumatism Association 1987 revised criteria for classification of RA and 50 age and sex matched healthy subjects without any major illness were considered as controls. MDA, NO and Vitamin E were estimated in serum. Results: The estimated mean levels (mean ± SD of serum MDA, NO, Vitamin E, in control group were 3.55 ± 0.30, 36.23 ± 7.03, 14.61 ± 1.74, respectively and in patients with RA they were 5.39 ± 0.79, 78.81 ± 8.56, 10.56 ± 1.72, respectively. The statistical analysis by unpaired t-test shows that the levels of serum MDA and NO significantly increased (p< 0.001 and the vitamin E levels were significantly decreased (p < 0.001 in RA patients when compared to healthy controls. Conclusion: The serum values of MDA, NO and Vitamin E all together provided fairly useful index of oxidative stress in RA patients. The results of current study support the concept of oxidative stress leading to tissue damage.

    To observe the effects of comprehensive therapy on serum secreted protein acidic and rich in cysteine (SPARC) levels in ankylosing spondylitis (AS) patients accompanied with osteoporosis (OP), and to explore the possible mechanisms for SPARC in AS patients accompanied with osteoporosis. Totally 48 AS patients accompanied with OP (Group A) were treated with massage, intravenous infusion of Cervus and Cucumis Polypeptide Injection, and Bushen Quhan Zhiwang Decoction (BQZD) for 3 months. At the same time, 45 normal healthy subjects were recruited as the normal control group (Group B). Serum SPARC levels were measured by ELISA in Group A before and after comprehensive therapy and in those of Group B. The levels of bone mineral density of femoral neck (FN BMD), bone mineral density of 2 -4 lumbar spine (L2-4 BMD), bone specific alkaline phosphatase (BSAP), tumor necrosis factor alpha (TNF-alpha), and transforming growth factor beta-1 (TGF-beta1) were detected. Meanwhile, Bath AS disease activity index (BASDAI) and Bath AS functional index (BASFI) were detected in Group A before and after treatment. The correlations between the aforesaid indices and serum SPARC levels were analyzed. Serum SPARC levels were significantly lower in those of Group A than in those of Group B (175. 30 +/- 72.04 micro/L vs 190. 52 +/- 86. 13 microg/ L, P <0. 01). Serum SPARC levels in those of Group A were negatively correlated with TNF-alpha (r = -0.261, P <0.01), positively with L2-4 BMD, TGF-beta1, and BSAP (r =0.437,0.256, 0.385, P <0.05, P <0.01). L2-4BMD and BSAP were independently predictors of serum SPARC in patients of Group A. After comprehensive therapy, the levels of TNF-alpha, BASDAI, and BASFI obviously decreased, TGF-beta1, BSAP, L2-4 BMD, and FN BMD obviously increased (P <0. 05, P <0. 01). The serum SPARC levels also significantly increased (188.32 +/- 87.50 microg/L, P <0. 05). Comprehensive therapy could effectively improve the bone metabolism, clinical symptoms and the

    Lymphocytes from healthy donors were incubated with serum samples from nine patients with Hashimoto thyroiditis and subsequently shown to be cytotoxic to chicken red blood cells (Ch. RBC) coated with thyroglobulin. Target cell death was estimated using a standard 51Cr release assay system. Lymphocytes pre-incubated with Hashimoto serum caused a mean% 51Cr release of 13·11±2·83 (SEM) from thyroglobulin-coated Ch. RBC and a mean% 51Cr release of 1·22±0·65 from uncoated Ch. RBC. Untreated lymphocytes caused no significant isotope release from either uncoated or thyroglobulin coated target cells. PMID:4800956

    The antiphospholipid syndrome (APS) is a systemic auto-immune disease with an unclear pathophysiology. The aim of our study was to understand the development of APS on a cellular level. Therefore, we analyzed the influence of human serum of APS patients on endothelial expression of specific genes and proteins in comparison to a control group. In this study, we analyzed the expression of ICAM-1, VCAM-1, E-selectin and annexin V in primary cultures of human umbilical vein endothelial cells (HUVEC) in response to 10% (v/v) serum of control patients (n = 6), patients with systemic lupus erythematosus (SLE) and no APS (n = 4) or APS patients (n = 9) for 24 h. Total RNA was prepared from confluent endothelial cell layers and mRNA expression of ICAM-1, VCAM-1 and E-selectin was analyzed by reverse transcription polymerase-chain reaction (RT-PCR). The protein expression was determined by Western blot. Serum protein concentrations of soluble forms of adhesion molecules sICAM-1 and sVCAM-1 were quantified by ELISA. Gene expression data were correlated with clinical parameters. The mRNA expression of ICAM-1 was increased in cells incubated with serum from APS patients (166 ± 22% of control; P = 0.023). Serum of patients with (SLE)/no APS caused a 1.4-fold higher ICAM-1 mRNA level. Western blot analysis showed an increase in protein expression of adhesion molecules ICAM-1 (260 ± 49%; P = 0.011) and VCAM-1 (357 ± 97%; P = 0.023) in cells that were incubated with serum from APS patients. Plasma analysis showed elevated levels of sVCAM-1 in APS patients (189 ± 34%; P = 0.045) compared to the levels measured in the control group. The sVCAM-1 plasma level was correlating with the frequency of abortions. An augmented expression of endothelial adhesion molecules is involved in the pathophysiology of patients with antiphospholipid syndrome. Copyright © 2017 Elsevier B.V. All rights reserved.

    Resistin is a novel adipokine that is suggested to be involved in inflammatory conditions and atherosclerosis. To investigate the prognostic importance of resistin in acute myocardial infarction (AMI) patients. Resistin levels were measured in a population of 132 patients with AMI, of whom 72 (54%) had a diagnosis of ST elevation myocardial infarction (STEMI), and 60 (46%) had non-ST elevation myocardial infarction (NSTEMI). Thirty-three consecutive subjects who were referred to elective coronary angiography due to chest pain evaluation with normal coronary angiograms served as controls. All patients were followed-up for the occurrence of major adverse cardiac events (MACE). There was a significant increase in serum resistin levels in patients with AMI compared to controls (3.71 ± 4.20 vs. 2.00 ± 1.05, p = 0.001, respectively). However, serum resistin levels were similar in patients with STEMI and NSTEMI. (4.26 ± 5.11 vs. 3.06 ± 2.64, p = 0.49, respectively). The patients with MACE had significantly higher levels of serum resistin levels compared to either the AMI or the control group (6.35 ± 5.47, p = 0.005, respectively). Logistic regression analysis revealed that resistin, left ventricular ejection fraction, and coronary artery bypass graft were independent predictors of MACE in AMI patients (OR = 1.11, 95% CI 1.01-1.22, p = 0.03 and OR = 3.84, 95% CI 1.26-11.71, p = 0.018, respectively). Serum resistin level was increased in patients with AMI and constituted a risk factor for MACE in this group.

    We reported previously that muscle quality and muscle strength provide clinically relevant predictors for better survival in hemodialysis patients. Iron overload might impair muscle function by its accumulation in muscle in such patients. Serum ferritin, a marker for body iron store, was examined for its association with handgrip strength (HGS) and muscle quality which was defined as the ratio of HGS to arm lean mass measured with dual-energy X-ray absorptiometry. In 300 Japanese hemodialysis patients, age, hemodialysis duration, body mass index, and serum albumin were 58.0 ±12.0 (mean ± standard deviation) years, 4.2 (1.8-10.4) (median [25th-75th percentile]) years, 20.4 ± 2.8 kg/m(2), 4.0 ± 0.3 g/dL, respectively. Hemoglobin and hematocrit were 8.9 ± 1.2 g/dL, and 28.8 ± 3.9%, respectively, whereas transferrin saturation and serum ferritin were 29.8 ± 11.0% and 100 (54-172) ng/mL, respectively. Serum ferritin significantly correlated in a positive manner with the total dose of iron orally administered during the previous 6 months (r = 0.185, P = .0013). HGS and muscle quality were 23.1 ± 10.4 kg and 11.6 ± 3.8 kg/kg, respectively. In multivariate analysis to elucidate the factors associated with HGS and muscle quality in 300 hemodialysis patients, which included transferrin saturation and log serum ferritin, in addition to age, gender, hemodialysis duration, the presence/absence of diabetes, body mass index as independent variables, log serum ferritin emerged as a significant and independent factor which associated in a negative fashion with HGS (β = -0.091, P = .0395) and tendency toward negative association with muscle quality (β = -0.100, P = .0754). In summary, the present study demonstrated the significant association of serum ferritin with HGS and muscle quality in hemodialysis patients and thus suggested that we should be careful of iron overload to avoid its possible harmful effect on muscle in such patients.

    2005-01-01

    Increased serum levels of certain immunologic markers including immunoglobulin G (IgG) anti-melanocyte/ vitiligo antibodies (V-IgG) and soluble interleukin-2 receptors (sIL-2R) are associated with augmented humoral and cellular immunity involved in melanocyte cytotoxicity during the active phase of non-segmental vitiligo. Recent reports have shown that, aspirin possesses a wide range of immunomodulatory and antioxidant properties. Therefore, the aim of the present study is to investigate the effect of long-term treatment of vitiligo patients with low-dose oral aspirin on serum V-IgG activity and sIL-2R concentration. The present study was carried out at the Vitiligo Unit, King Abdul-Aziz University Medical Center, Jeddah, Kingdom of Saudi Arabia between March and October 2003. Eighteen female and 14 male patients with a recent onset of non-segmental vitiligo were divided into 2 equal groups. One group received a daily single dose of oral aspirin (300 mg) and the second group received only placebo for a period of 12 weeks. Serum V-IgG activity and sIL-2R concentration were determined before and at the end of treatment period. The V-IgG activity was measured using cellular enzyme-linked immunosorbent assay (ELISA) following incubation of IgG antibodies with an adult cultured melanocytes. Serum sIL-2R concentration was measured using the highly sensitive quantitative sandwich ELISA utilizing a commercially available kit. As expected, the serum V-IgG activity and sIL-2R concentration of the active vitiligo patients (0.81 +/- 0.23 optical density (O.D.), 1428 +/- 510 pg/ml) were significantly increased compared with that of controls (0.27 +/- 0.1 O.D., 846 +/- 312 pg/ml; p<0.05, p<0.01). Aspirin-treated vitiligo patients showed significant decrease in serum V-IgG activity and sIL-2R concentration (0.32 +/- 0.08 O.D., 756 +/- 216 pg/ml) compared with that of placebo-treated patients (0.83 +/- 0.19 O.D., 1327 +/- 392 pg/ml; p<0.01).

    The role of progranulin in individuals with metabolic syndrome is not exactly clear.We aimed to assess the serum level of progranulin in type 2 diabetic patients with and without metabolic syndrome and compare them with healthy controls. The study included 60 patients with type 2 diabetes and 30 healthy individuals as control groups. Biochemical parameters and progranulin levels were determined. Subjects with metabolic syndrome showed significantly higher levels of triglyceride, waist circumference, BMI, systolic and diastolic blood pressure than subjects without metabolic syndrome and the control groups, while HDL-cholesterol level was significantly lower in subjects with metabolic syndrome. Fasting blood sugar was significantly higher in type 2 diabetic patients than in the control groups. Serum level of progranulin was slightly increased in subjects with metabolic syndrome. Serum progranulin level had no significant relationship with metabolic syndrome components. Serum progranulin was also not dependent on cardiometabolic risk factors for subjects with metabolic syndrome, but it could be considered for the management of type 2 diabetes mellitus. Further studies are recommended to explain the effect of progranulin on the pathogenesis of metabolic risk factors.

    Full Text Available Background. Fetuin-A (FA suppresses arterial calcification, promotes insulin resistance, and appears to be elevated in patients with cardiovascular diseases (CVD, but the data is still inconsistent. To clarify the correlation between serum FA levels and the presence and severity of CVDs, we performed this meta-analysis. Method. Potential relevant studies were identified covering the following databases: PubMed, Embase, Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, China BioMedicine (CBM, and China National Knowledge Infrastructure (CNKI databases. Data from eligible studies were extracted and included in the meta-analysis using a random-effects model. Results. Ten case-control studies, including 1,281 patients with CVDs and 2,663 healthy controls, were included. The results showed significant differences in serum levels of FA between the CVDs patients and the healthy controls (SMD = 1.36, 95%CI: 0.37–2.36, P=0.007. Ethnicity-subgroup analysis implied that low serum FA levels are related to CVDs in Caucasians (SMD = 1.73, 95%CI: 0.20–3.26, P=0.026, but not in Asians (SMD = 1.04, 95%CI: −0.33–2.40, P=0.138. Conclusion. The data indicated that decreased serum FA level is correlated with the development of CVDs. FA might be clinically valuable for reflecting the progression of CVDs.

    IL-33 is a recently identified cytokine, encoded by the IL-33 gene, which is a member of the IL-1 family that drives the production of T-helper-2 (Th-2)-associated cytokines. Serum levels of IL-33 have been reported to be up-regulated in various T-helper (Th)-1/Th-17-mediated diseases, such as psoriasis, rheumatoid arthritis, and inflammatory bowel. To investigate whether cytokine imbalance plays a role in the pathogenesis of vitiligo, we performed a case-control association study by enzyme-linked immunosorbent assay of IL-33 in our patients. IL-33 serum levels were measured by a quantitative enzyme immunoassay technique in patients with non-segmental generalized vitiligo and compared with those of healthy controls. IL-33 serum levels in patients with vitiligo were significantly increased than those in healthy controls. There was a positive correlation of IL-33 serum levels with extension of vitiligo and disease activity. This study suggests a possible systemic role of IL-33 in the pathogenesis of vitiligo. Inhibiting IL-33 activity might be a novel therapeutic strategy in the treatment of autoimmune inflammatory disease, like vitiligo.

    Full Text Available Micronutrients serve many important functions in our body and altered levels of heavy and trace metals are associated with cutaneous and systemic disorders. Vesicular palmoplantar eczema is an entity whose etiopathogenesis is a mystery. In this prospective case-noncase study blood levels of Zinc and Cadmium in 37 patients of chronic vesiculobullous hand dermatitis were estimated and compared with 40 noncases with similar age and gender distributions. Low serum Zinc levels were found in patients as compared to noncases. The mean difference of serum Zinc between the case and noncase groups was 27.26; the mean value of serum Zinc between the two groups was statistically significant (p<0.0001. However, elevated Cadmium levels were detected in only 5 patients and in none of the noncases. The mean concentration of serum Cadmium was 2.32±0.38 μg/dL, with a range of 1.90–2.80 μg/dL for the five cases in whom Cadmium was detected. Various toxic and trace metals can interact by influencing each other’s absorption, retention, distribution, and bioavailability in the body. The clinical significance of this finding lies in the possible beneficial role of Zinc supplementation in the therapy of chronic vesiculobullous hand dermatitis.

    Directory of Open Access Journals (Sweden)

    Christian Dejaco

    Full Text Available Previous studies suggest a role for eotaxin-3, TARC/CCL17 and IgG4 in newly-diagnosed patients with eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss with highly active disease. The role of these biomarkers in relapsing disease is unclear.Serum levels of TARC/CCL17, eotaxin-3, IgG4, and IgG4/IgG ratio were determined in serum samples from a longitudinal cohort of patients with EGPA (105 visits of 25 patients. Epidemiological, clinical and laboratory data were available for all visits.At the first visit, 80% of patients were using glucocorticoids and 68% additional immunosuppressive drugs. Disease flares were seen at 18 visits. The median BVAS and BVAS/WG scores at time of relapse were 4 and 2, respectively. None of the biomarkers tested were useful to discriminate between active disease and remission. Patients treated with prednisone had lower eotaxin-3 and eosinophil levels compared to patients not taking glucocorticoids irrespective of disease activity. Use of immunosuppressive agents was not associated with biomarker levels.Serum levels of TARC/CCL17, eotaxin-3, IgG4, and IgG4/IgG ratio do not clearly differentiate active and inactive disease in established EGPA. Defining biomarkers in EGPA remains a challenge especially during times of glucocorticoid use.

    BACKGROUND: Paraquat (PQ) is a world-wide used herbicide and also a type of common poison for suicide and accidental poisoning. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals. So far, lack of systematic research on the reliability of the method and the correlation between clinical features of patients with PQ poisoning and the test results has restricted the clinical use of spectrophotometry. This study aimed to evaluate the reliability and value of spectrophotometry in detecting the concentration of serum PQ. METHODS: The wavelengths for detecting the concentration of serum PQ by common and second-derivative spectrophotometry were determined. Second-derivative spectrophotometry was applied to detect the concentration of serum PQ. The linear range and precision for detection of PQ concentration by this method were confirmed. The concentration of serum PQ shown by second-derivative spectrophotometry and HPLC were compared in 8 patients with PQ poisoning. Altogether 21 patients with acute poisoning 4 hours after PQ ingestion treated in the period of October 2008 to September 2010 were retrospectively reviewed. The patients were divided into higher and lower than 1.8 μg/mL groups based on their concentrations of serum PQ measured by second-derivative spectrophotometry on admission. The severity of clinical manifestations between the two groups were analyzed with Student's t test or Fisher's exact test. RESULTS: The absorption peak of 257 nm could not be found when common spectrophotometry was used to detect the PQ concentration in serum. The calibration curve in the 0.4–8.0 μg/mL range for PQ concentration shown by second-derivative spectrophotometry obeyed Beer's law with r=0.996. The average recovery rates of PQ were within a range of 95.0% to 99.5%, relative

    It has recently been recognized that human serum contains a protein that specifically binds human growth hormone (hGH). This protein has the same restricted specificity for hGH as the membrane-bound GH receptor. To determine whether the GH-binding protein is a derivative of, or otherwise related to, the GH receptor, the authors have examined the serum of three patients with Laron-type dwarfism, a condition in which GH refractoriness has been attributed to a defect in the GH receptor. The binding of /sup 125/I-labeled hGH incubated with serum has been measured after gel filtration of the serum through an Ultrogel AcA 44 minicolumn. Results are expressed as percent of specifically bound /sup 125/I-hGH and as specific binding relative to that of a reference serum after correction is made for endogenous GH. The mean +/- SEM of specific binding of sera from eight normal adults (26-46 years of age) was 21.6 +/- 0.45%, and the relative specific binding was 101.1 +/- 8.6%. Sera from 11 normal children had lower specific binding of 12.5 +/- 1.95% and relative specific binding of 56.6 +/- 9.1%. Sera from three children with Laron-type dwarfism lacked any demonstrable GH binding, whereas sera from 10 other children with other types of nonpituitary short stature had normal relative specific binding. They suggest that the serum GH-binding protein is a soluble derivative of the GH receptor. Measurement of the serum GH-binding protein may permit recognition of other abnormalities of the GH receptor.

Brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are important for activity-dependent neuronal function and synaptic modulation and it is considered that these mechanisms are important in sleep regulation. We hypothesised......Narcolepsy is a lifelong sleep disorder characterized by excessive daytime sleepiness, sudden loss of muscle tone (cataplexy), fragmentation of nocturnal sleep and sleep paralysis. The symptoms of the disease strongly correlate with a reduction in hypocretin levels in CSF and a reduction...... that serum levels of these factors are altered in patients with narcolepsy compared to healthy controls without sleep disturbances. Polysomnography data was obtained and serum BDNF and NGF levels measured using ELISA, while hypocretin was measured using RIA. Serum BDNF levels were significantly higher...

Results Serum AChR-Ab, Titin-Ab and RyR-Ab were detected positive respectively in 68.13% (124/182, 64.29% (117/182 and 67.03% (122/182 of patients in MG group. The positive rates of those antibodies in MG group were significantly higher than those in OND group (P = 0.000, for all and control group (P = 0.000, for all. When 3 antibodies coexisted, the sensitivity in the diagnosis of MG was 41.21%, with 99.40% of specificity. There was no significant difference in the positive rate of serum AChR-Ab, Titin-Ab and RyR-Ab between early-onset MG subgroup and late-onset MG subgroup (P > 0.05, for all. The positive rates of AChR-Ab were significantly higher in MG patients with thymoma than in those without thymoma (P = 0.004. There was no significant difference in the positive rate of Titin-Ab and RyR-Ab between MG with thymoma subgroup and MG without thymoma subgroup (P > 0.05, for all. The prevalence of AChR-Ab in generalized MG (GMG atients (Ⅱa and Ⅱb was higher than those in ocular MG (OMG patients (typeⅠ; P = 0.005, 0.012. There was no significant difference in the positive rate of Titin-Ab and RyR-Ab between GMG subgroup and OMG subgroup (P > 0.05, for all. Conclusions Serum AChR-Ab, Titin-Ab and RyR-Ab can be used as ndicators of the diagnosis of MG. Patients with 3 coexisted positive antibodies are highly suspected as MG. Higher AChR-Ab level in serum of OMG patients indicates the possibility of progressing to GMG. DOI: 10.3969/j.issn.1672-6731.2016.10.007

    Full Text Available Background: Thalassemia is a hereditary hemoglobinopathy whose most common complication is cardiac involvement which ends up in these patients’ death. Since troponin is a sensitive and specific marker for the detection of microinfarct, we studied the relationship between troponin and ferritin serum levels for early diagnosis of cardiac involvement in these patients. Materials and Methods: This case-control study was performed on 80 patients, including 40 patients with major thalassemia and normal echocardiography and 40 healthy volunteers ranging from 6 months to 16 years old. All the children were examined and the eligible children who were not infected with known heart disease, iron deficiency anemia, kidney disease, diabetes, fever, and systemic diseases were enrolled into the study after obtaining written informed consents from their parents. At 8:00 A.M. before breakfast, 5cc blood was drawn from these children. After collecting the samples, ferritin and troponin serum levels were evaluated using ELISA and electro- kymonolonsense methods, respectively. The gathered data were analyzed through the SPSS statistical software (v. 20 and T-test. Besides, P value<0.05 was considered as statistically significant. Results: The study results revealed a significant difference between the two groups regarding the mean of the serum levels of troponin (P=0.045 and ferritin (P=0.001. In this study, no significant correlation was observed between serum troponin and ferritin levels and age and BMI in the two groups. Also, no significant relationship was found between serum troponin level and sex (P=0.264. Conclusions: In microinfarct, troponin increases independent of ferritin; therefore, it can be used for early detection of cardiac involvement in thalassemia patients to determine the sub-clinical effects.

    Full Text Available Objective: To explore the effect of minimally invasive surgery and transforaminal lumbar interbody fusion (TLIF on the related serum factors in patients with lumbar degenerative disease. Methods: A total of 100 patients with lumbar degenerative disease who were admitted in our hospital from May, 2014 to May, 2016 were included in the study and divided into the observation group and the control group according to different surgical methods. The patients in the observation group were given MIS-TLIF, while the patients in the control group were given the traditional TLIF. The peripheral venous blood before operation, 2 h, 4 h, 8 h and 24 h after operation in the two groups was collected, and centrifuged for the serum. ELISA was used to detect the serum IL-6 and IL-10 levels. The peripheral venous blood before operation, 1 h, 3 h, 5 h and 7 d after operation in the two groups was collected. DGKC velocity method was used to detect CK activity and fusion rate. The fusion grade was evaluated 6 months after operation according to Bridwell fusion grading standard. Results: The serum IL-6 and IL-10 levels 2 h, 4 h, 8 h and 24 h after operation in the two groups were significantly elevated when compared with before operation, and the serum IL-6 and IL-10 levels at each timing point after operation in the observation group were significantly lower than those in the control group. CK activity 1 d, 3 d, 5 d, and 7d after operation in the two groups was significantly elevated when compared with before operation, and CK activity at each timing point after operation in the observation group was significantly lower than that in the control group. Conclusions: MISTLIF has a small damage on the tissues, can effectively alleviate the inflammatory reaction, and preferably retain the stable structure of posterior column, whose advantage is significantly superior to that by the traditional TLIF.

    Full Text Available Alzheimer’s disease (AD is a multifactorial disease but its aetiology and pathophisiology are still not fully understood. Epidemiologic studies examining the association between lipids and dementia have reported conflicting results. High total cholesterol has been associated with both an increased, and decreased, risk of AD and/or vascular dementia (VAD, whereas other studies found no association. The aim of this study was to investigate the serum lipids concentration in patients with probable AD, as well as possible correlation between serum lipids concentrations and cognitive impairment.Our cross-sectional study included 30 patients with probable AD and 30 age and sex matched control subjects. The probable AD was clinically diagnosed by NINCDS-ADRDA criteria. Serum total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C and triglyceride (TG levels were determined at the initial assessment using standard enzymatic colorimetric techniques. Low-den- sity lipoprotein cholesterol (LDL-C and very low density lipoprotein cholesterol (VLDL-C levels were calculated. Subjects with probable AD had significantly lower serum TG (p<0,01, TC (p<0,05, LDL-C (p<0,05 and VLDL-C (p<0,01 compared to the control group. We did not observe signifi-cant difference in HDL-C level between patients with probable AD and control subjects. Negative, although not significant correlation between TG, TC and VLDL-C and MMSE in patients with AD was observed. In the control group of subjects there was a negative correlation between TC and MMSE but it was not statistically significant (r = -0,28. Further studies are required to explore the possibility for serum lipids to serve as diagnostic and therapeutic markers of AD.

    The idiopathic basal ganglia calcification (Fahr syndrome) may occur due to senility. Fetuin-A is a negative acute phase reactant which inhibits calcium-phosphorus precipitation and vascular calcification. In this study, we aimed to evaluate whether serum fetuin-A levels correlate with bilateral basal ganglia calcification. Forty-five patients who had bilateral basal ganglia calcification on brain CT were selected according to the inclusion and exclusion criteria, and 45 age and gender-matched subjects without basal ganglia calcification were included for the control group. Serum fetuin-A levels were measured from venous blood samples. All participants were divided into two groups; with and without basal ganglia calcification. These groups were divided into subgroups regarding age (18-32 and 33-45 years of age) and gender (male, female). We detected lower levels of serum fetuin-A in patients with basal ganglia calcification compared with the subjects without basal ganglia calcification. In all subgroups (female, male, 18-32 years and 33-45 years), mean fetuin-A levels were significantly lower in patients with basal ganglia calcification (p = 0.017, p = 0.014, p = 0.024, p = 0.026, p = 0.01 respectively). And statistically significantly lower levels of fetuin-A was found to be correlated with the increasing densities of calcification in the calcified basal ganglia group (p-value: <0.001). Considering the role of fetuin-A in tissue calcification and inflammation, higher serum fetuin-A levels should be measured in patients with basal ganglia calcification. We believe that the measurement of serum fetuin-A may play a role in the prediction of basal ganglia calcification as a biomarker. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of this study was to examine whether anorexia nervosa and bulimia nervosa are accompanied by lower serum activity of dipeptidyl peptidase IV (DPP IV, EC 3.4.14.5), a membrane-bound serine protease that catalyses the cleavage of dipeptides from the amino-terminus of oligo- and polypeptides. Substrates of DPP IV are, amongst others, neuroactive eptides, such as substance P, growth hormone releasing hormone, neuropeptide Y, and peptide YY. DPP IV activity was measured in the serum of 21 women with anorexia nervosa, 21 women with bulimia nervosa and 18 normal women. Serum DPP IV activity was significantly lower in patients with anorexia nervosa and bulimia nervosa than in the normal controls. In the total study group, there were significant and inverse relationships between serum DPP IV activity and the total scores on the Bulimic Investigatory Test, Edinburgh, the Eating Disorder Inventory (EDI) and the Hamilton Depression Rating Scale. In the total study group no significant correlations between DPP IV and age, body weight or body mass index could be found. It is concluded that lowered serum DPP IV activity takes part in the pathophysiology of anorexia and bulimia nervosa. It is hypothesised that a combined dysregulation of DPP IV and neuroactive peptides, which are substrates of DPP IV, e.g. neuropeptide Y and peptide YY, could be an integral component of eating disorders.

    The effects of a strict uncooked vegan diet on serum lipid and sterol concentrations were studied in patients with rheumatoid arthritis. The subjects were randomized into a vegan diet group (n 16), who consumed a vegan diet for 2-3 months, or into a control group (n 13), who continued their usual omnivorous diets. Serum total and LDL-cholesterol and -phospholipid concentrations were significantly decreased by the vegan diet. The levels of serum cholestanol and lathosterol also decreased, but serum cholestanol:total cholesterol and lathosterol:total cholesterol did not change. The effect of a vegan diet on serum plant sterols was divergent as the concentration of campesterol decreased while that of sitosterol increased. This effect resulted in a significantly greater sitosterol:campesterol value in the vegan diet group than in the control group (1.48 (SD 0.39) v. 0.72 (SD 0.14); P vegan diet changes the relative absorption rates of these sterols and/or their biliary clearance.

    Glioblastomas progress rapidly making response evaluation using MRI insufficient since treatment effects are not detectable until months after initiation of treatment. Thus, there is a strong need for supplementary biomarkers that could provide reliable and early assessment of treatment efficacy. Analysis of alterations in the metabolome may be a source for identification of new biomarker patterns harboring predictive information. Ideally, the biomarkers should be found within an easily accessible compartment such as the blood. Using gas-chromatographic- time-of-flight-mass spectroscopy we have analyzed serum samples from 11 patients with glioblastoma during the initial phase of radiotherapy. Fasting serum samples were collected at admittance, on the same day as, but before first treatment and in the morning after the second and fifth dose of radiation. The acquired data was analyzed and evaluated by chemometrics based bioinformatics methods. Our findings were compared and discussed in relation to previous data from microdialysis in tumor tissue, i.e. the extracellular compartment, from the same patients. We found a significant change in metabolite pattern in serum comparing samples taken before radiotherapy to samples taken during early radiotherapy. In all, 68 metabolites were lowered in concentration following treatment while 16 metabolites were elevated in concentration. All detected and identified amino acids and fatty acids together with myo-inositol, creatinine, and urea were among the metabolites that decreased in concentration during treatment, while citric acid was among the metabolites that increased in concentration. Furthermore, when comparing results from the serum analysis with findings in tumor extracellular fluid we found a common change in metabolite patterns in both compartments on an individual patient level. On an individual metabolite level similar changes in ornithine, tyrosine and urea were detected. However, in serum, glutamine and

    Allograft rejection is an important cause of early and long-term graft loss in kidney transplant recipients. Tumor necrosis factor-alpha promotes T-cell activation, the key reaction leading to allograft rejection. Here, we investigated whether serum and urinary tumor necrosis factor-alpha levels can predict allograft rejection. This study included 65 living related-donor renal transplant recipients with mean follow-up of 26 ± 9 months. Serum and urinary tumor necrosis factor-alpha levels were measured at pretransplant and at posttransplant time points (days 1 and 7 and months 3 and 6); serum creatinine levels were also monitored during posttransplant follow-up. Standard enzyme-linked immunoabsorbent assay was used to detect tumor necrosis factor-alpha levels. Clinical variables were monitored. Nine of 65 patients (13.8%) had biopsy-proven rejection during follow-up. Preoperative serum and urinary tumor necrosis factor-alpha levels were not significantly different when we compared patients with and without rejection. Serum tumor necrosis factor-alpha levels (in pg/mL) were significantly higher in the allograft rejection versus nonrejection group at day 7 (11.5 ± 4.7 vs 15.4 ± 5.8; P = .029) and month 1 (11.1 ± 4.8 vs 17.8 ± 10.9; P =.003). Urinary tumor necrosis factor-alpha levels (in pg/mL) were also elevated in the allograft rejection versus the nonrejection group at days 1 (10.2 ± 2.5 vs 14.1 ± 6.8; P = .002) and 7 (9.8 ± 2.2 vs 14.5 ± 2.7; P tumor necrosis factor-alpha has a role in diagnosing renal transplant rejection. Serum and urinary tumor necrosis factor-alpha levels may be a possible predictor for allograft rejection.

    Full Text Available Abstract Background More than a million diagnostic cardiac catheterizations are performed annually in the US for evaluation of coronary artery anatomy and the presence of atherosclerosis. Nearly half of these patients have no significant coronary lesions or do not require mechanical or surgical revascularization. Consequently, the ability to rule out clinically significant coronary artery disease (CAD using low cost, low risk tests of serum biomarkers in even a small percentage of patients with normal coronary arteries could be highly beneficial. Methods Serum from 359 symptomatic subjects referred for catheterization was interrogated for proteins involved in atherogenesis, atherosclerosis, and plaque vulnerability. Coronary angiography classified 150 patients without flow-limiting CAD who did not require percutaneous intervention (PCI while 209 required coronary revascularization (stents, angioplasty, or coronary artery bypass graft surgery. Continuous variables were compared across the two patient groups for each analyte including calculation of false discovery rate (FDR ≤ 1% and Q value (P value for statistical significance adjusted to ≤ 0.01. Results Significant differences were detected in circulating proteins from patients requiring revascularization including increased apolipoprotein B100 (APO-B100, C-reactive protein (CRP, fibrinogen, vascular cell adhesion molecule 1 (VCAM-1, myeloperoxidase (MPO, resistin, osteopontin, interleukin (IL-1β, IL-6, IL-10 and N-terminal fragment protein precursor brain natriuretic peptide (NT-pBNP and decreased apolipoprotein A1 (APO-A1. Biomarker classification signatures comprising up to 5 analytes were identified using a tunable scoring function trained against 239 samples and validated with 120 additional samples. A total of 14 overlapping signatures classified patients without significant coronary disease (38% to 59% specificity while maintaining 95% sensitivity for patients requiring

Chemiluminescence–linked immunoassay was used to detect serum IGFBP7 levels. For the second group patients, IGFBP7 and C-reactive protein (CRP levels were measured both on the admission day and on the discharge day.Results: Among the first group AECOPD patients, serum IGFBP7 levels were significantly ­elevated in AECOPD patients in the intensive care unit (ICU; 52.92±16.32 ng/mL, and in ­hospitalized AECOPD patients not in ICU (40.66±13.9, compared to healthy subjects (30.3±7.09 ng/mL; P<0.01. For the second group AECOPD patients, the increased IGFBP7 levels reduced after the patients had recovered (34.42±11.88 vs 27.24±7.2 ng/mL; P<0.01. During AE, the correlation coefficient between IGFBP7 and CRP was 0.357. In receiver operating characteristic analysis, the area under the curve was 0.799 for CRP, and 0.663 for IGFBP7 in distinguishing patients with AECOPD on the admission day from the discharge day.Conclusion: Serum IGFBP7 levels were raised during AECOPD. Similar to the expression pattern of CRP, the IGFBP7 levels reduced after convalescence, suggesting that IGFBP7

    The effects of zinc therapy on some trace elements in serum and skin had been studied in forty patients with psoriasis and a topic dermatitis with age range between 20-65 years. Patients were treated with 330 mg oral zinc sulfate for 12 week. Significant increases in both serum and skin copper levels were detected. Also, serum and skin calcium and magnesium levels in both psoriatic and a topic patients were significantly decreased, while iron level was significantly increased in psoriasis and significantly decreased in a topic patients. It could be conclude that zinc therapy could affect copper, calcium, iron and magnesium levels in both psoriatic and a topic patients

    To study the serum tumor markers in patients with multiple abnormal concentration of radiopharmaceuticals in whole body bone imagine, 73 patients with malignancy were under a whole body bone scan. The serum tumor markers levels of AFP, CEA, CA125, CA15-3 and CA19-9 were measured in 73 patients and 37 normal people. The results showed that there was significant difference only on serum CEA level (P<0.005), and no significant difference on CA125, CA15-3 and CA19-9 levels (P<0.05) between 36 patients with multiple abnormal concentration and the others with normal bone imagine. The serum levels of CEA, CA125 and CA19-9 in patients were significant higher than that of normal controls (P<0.005). Combined the whole body bone scan and detection of serum tumor markers might be regarded as clinical significance for the diagnosis of bone metastases. (authors)

    Objective: To explore the clinical significance of the changes of serum growth hormone (GH) and insulin (IS) levels in patients with coronary heart disease (CHD). Methods: Serum GH and IS levels were determined with RIA in 120 patients with CHD and 50 controls. Results: The serum levels of GH in patients with CHD (127.16 ± 37.9 pmol/L) were significantly lower than those in controls (152.0 ± 41.2 pmol/L) (t=3.819, P 0.05). In patients complicated with heart failure, the serum GH levels were significantly lower than those in patients without heart failure (P 0.05). The serum IS levels were significantly higher in patients developing myocardial infarction than those in patients without this complication (P 0.05). In the patients succumbed in the hospital, both serum GH and IS levels were significantly lower than those in the patients finally recovered (P<0.05). Conclusion: In this study, serum GH levels were much lower in CHD patients. Whatever explanation of this finding is at best speculative and further study is mandatory. (authors)

    A study was done to ascertain whether the serum free T4 measured by free T4 radioimmunoassay kits would, like equilibrium dialysis, be normal in patients with familial dysalbuminemic hyperthyroxinemia. Five free T4 radioimmunoassay kits were used to measure free T4 in serum samples from 19 patients with familial dysalbuminemic hyperthyroxinemia and 20 healthy volunteers. Values (mean +/- SE) for T4, free T4 index, and free T4 (equilibrium dialysis) in these normal subjects and patients with familial dysalbuminemic hyperthyroxinemia, respectively, were as follows: T4, 8.1 +/- 0.2 and 18.3 +/- 0.7 μg/dL; free T4 index, 3.1 +/- 0.1 and 7.3 +/- 0.3 μg/dL; free T4, 1.4 +/- 0.1 and 1.2 +/- 0.1 ng/dL. The following free T4 radioimmunoassay methods were used: antibody coated microfine silica, microencapsulated antibody, two-step antibody-coated tube, and one-step 125 I-T4 analog (2 kits). The present findings in patients with familial dysalbuminemic hyperthyroxinemia and previous observations in ill euthyroid patients suggest that serum free T4 measured by some radioimmunoassay methods must be interpreted with caution in these two clinical situations

    Glioblastoma multiforme (GBM) is the most frequent malignant brain tumor in adults, and its prognosis remains dismal despite intensive research and therapeutic advances. Diagnostic biomarkers would be clinically meaningful to allow for early detection of the tumor and for those cases in which surgery is contraindicated or biopsy results are inconclusive. Recent findings show that GBM cells release microvesicles that contain a select subset of cellular proteins and RNA. The aim of this hypothesis-generating study was to assess the diagnostic potential of miRNAs found in microvesicles isolated from the serum of GBM patients. To control disease heterogeneity, we used patients with newly diagnosed GBM. In the discovery stage, PCR-based TaqMan Low Density Arrays followed by individual quantitative reverse transcriptase polymerase chain reaction were used to test the differences in the miRNA expression levels of serum microvesicles among 25 GBM patients and healthy controls paired by age and sex. The detected noncoding RNAs were then validated in another 50 GBM patients. We found that the expression levels of 1 small noncoding RNA (RNU6-1) and 2 microRNAs (miR-320 and miR-574-3p) were significantly associated with a GBM diagnosis. In addition, RNU6-1 was consistently an independent predictor of a GBM diagnosis. Altogether our results uncovered a small noncoding RNA signature in microvesicles isolated from GBM patient serum that could be used as a fast and reliable differential diagnostic biomarker.

    During monitoring of monthly medians of results from patients undertaken to assess analytical stability in routine laboratory performance, the medians for serum sodium for male and female patients were found to be significantly related. Daily, weekly and monthly patient medians of serum sodium for both male and female patients were calculated from results obtained on samples from the population >18 years on three analysers in the hospital laboratory. The half-range of medians was applied as an estimate of the maximum bias. Further, the ratios between the two medians were calculated. The medians of both genders demonstrated dispersions over time, but they were closely connected in like patterns, which were confirmed by the half-range of the ratios of medians for males and females that varied from 0.36% for daily, 0.14% for weekly and 0.036% for monthly ratios over all instruments. The tight relationship between the gender medians for serum sodium is only possible when raw laboratory data are used for calculation. The two patient medians can be used to confirm both and are useful as independent estimates of analytical bias during constant calibration periods. In contrast to the gender combined median, the estimate of analytical bias can be confirmed further by calculation of the ratios of medians for males and females.

    Objective: To study the influence of 131 I therapy on the auto-immune status of hyperthyroid patients through measurement of the changes of serum TNF-α and sTNFR II levels. Methods: Serum levels of TNF-α and sTNFR II were measured with IRA and ELISA respectively in 36 hyperthyroid patients and 31 controls. Six to twelve months after 131 I therapy, the serum levels were again measured in the patients. Results: The 36 patients fell into two groups after treatment: 27 with thyroid function normalized (cured) and 9 remained hyper- thyroid (treatment failure). Before treatment, the serum TNF-α and sTNFR II levels in both groups of patients were significantly higher than those in the controls (p 0.05). In the treatment failure group, serum levels of TNF-α and sTNFR II were not much decreased after therapy (vs before treatment, p>0.05). Serum TNF-α levels were positively correlated to the serum sTNFR II levels in the patients (r=0.264, p 3 , FT 4 levels (r=0.354, p 131 I therapy would effectively suppress the auto-immune status in hyperthyroid patients; changes of serum TNF-α and sTNFR II levels would reflect the result

    MicroRNAs (miRNAs) play critical regulatory roles in the physiological and pathological processes. The high stability of miRNAs in human serum represents attractive novel diagnostic biomarkers of clinical conditions. Several studies have shown that aberrant expression of miRNAs in human cancer including lung cancer, but little is known about their effects on some infectious lung diseases such as pulmonary tuberculosis (TB) and pneumonia. In this study, we investigated miRNA expression pattern in serum of Egyptian patients with lung cancer, TB, and pneumonia compared with matched healthy controls. Using microarray-based expression profiling followed by real-time quantitative polymerase chain reaction validation, we compared the levels of a series of circulating miRNAs (miR-21, miR-155, miR-182, and miR-197) in serum from patients with lung cancer (n = 65), pulmonary tuberculosis (n = 29), pneumonia (n = 29), and transudate (n = 16) compared with matched healthy controls (n = 37). MiRNA SNORD68 was the housekeeping endogenous control. We found that the serum levels of miR-21, miR-155, and miR-197 were significantly elevated in the patients with lung cancer and pneumonia whereas miR-182 and miR-197 levels were increased only in patients with lung cancer and TB, respectively, compared with controls. Receiver operating characteristic analysis revealed that miR-182, miR-155, and miR-197 have superior diagnostic potential in discriminating patients with lung cancer, pneumonia, and TB, respectively, from controls. Our results conclude that the differential expression of the four studied miRNAs can be potential non-invasive biomarkers for patients with lung cancer, TB and pneumonia.

    The aim of the study was to assess the association of serum uric acid levels with microalbuminuria -urinary albumin excretion (UAE)> or = 30mg/24h-. Cross-sectional study in 429 (220 women) hypertensive, non diabetic, never treated patients (mean age: 47 years) with glomerular filtration rate > or =60ml/min/1.73m(2). The prevalence of microalbuminuria was 20.5%; 18% had hyperuricemia and 47% fulfilled the criteria for metabolic syndrome (MS). Baseline UAE correlated in the unvaried analysis to diastolic blood pressure, waist circumference, high-density lipoprotein cholesterol and uric acid. In multiple linear regression models, only MS (beta=0.113; p=0.03), and serum uric acid values (beta=0.04; p=0.05) were independently associated with logUAE, after adjustment for age and sex. Hyperuricemia (serum uric acid level > or =7.0mg/dl for men and > or =6.5mg/dl for women; odds ratio=2.18; 95% confidence interval, 1.21-3.92; p=0.010), and MS (odds ratio=2.16; 95% confidence interval, 1.32-3.53; p=0.002) were independently associated with a higher risk of microalbuminuria in multiple logistic regression analyses. The prevalence of microalbuminuria was 45.8% in patients with coexistent MS and hyperuricemia, as compared to 13.6% in hypertensive patients without it (p<0.001). In patients with concomitant MS and hyperuricemia the probability of being microalbuminuric was 3.7 times higher than in patients without those factors. Serum uric acid level is associated with microalbuminuria. Coexistence of MS and hyperuricemia in hypertensive patients increases almost 4 times the odds of being microalbuminuric.

    Spinal cord injury (SCI) patients with pressure sores were studied before and after surgical intervention for ulcer healing and compared with matched SCI patients without sores and with patients with pressure sores and other diseases. To analyse the relationship between pressure sores and anaemia and serum protein alteration in SCI patients. To study the pathogenesis of these alterations and suggest appropriate therapy. Spinal cord unit in Rome, Italy. A total of 13 SCI patients with pressure sores, 13 comparable patients without pressure sores and four patients with other diseases and pressure sores. Haematochemical parameters. Patients with pressure sore showed significant decreased red cells, decreased haemoglobin and haematocrit, increased white cells and ferritin and decreased transferrin and transferrin saturation; total hypoproteinemia and hypoalbuminemia with increased Alfa-1 and gamma globulins increased erythrocyte sedimentation rate and C-reactive protein were also present. The alterations returned to normal after surgical intervention for pressure sore healing. Patients with pressure sores suffer from anaemia and serum protein alteration that fells within the range of metabolic alteration of chronic disorders and neoplastic diseases. The alterations depend on a decreased utilisation of iron stores in the reticuloendothelial system and on inhibition of the hepatic synthesis of albumin. With regard to treatment, iron treatment should be avoided because of the risk of haemochromatosis.

    Full Text Available The aim of this research was to expose the relation between tumor necrosis factor alpha (TNF-α in the peritoneal fluid and in the serum of endometriosis patients. It was conducted at Dr. Muwardi Hospital Surakarta. Twenty patients undergoing laparoscopic operation because of endometriosis indication (Endometriosis Group, 20 women (aged 23 to 40 who undergo interval sterilization by means of laparoscopic technique. During laparoscopic operation, peritoneal fluid is taken to examine TNF-α by ELISA technique. At the same time, the serum is also taken to examine TNF-α by the same technique. The research result indicated that by independent sample t-test, the TNF-α concentration in the Endometriosis Group is quite different from the control group (P=0.00. The simple linear regression test shows a strong positive one-way correlative relation between TNF-α concentration in the peritoneal fluid and TNF-α concentration in the serum in the Endometriosis Group. The research result indicated that the TNF-α concentration in the serum can be used as a reflection of endometriosis. A statistical test is done to find the limit value based on sensitivity and specification.

    Full Text Available Background. Natalizumab is a highly effective treatment approved for multiple sclerosis (MS. The opening of the blood-brain barrier mediated by matrix metalloproteinases (MMPs is considered a crucial step in MS pathogenesis. Our goal was to verify the utility of serum levels of active MMP-2 and MMP-9 as biomarkers in twenty MS patients treated with Natalizumab. Methods. Serum levels of active MMP-2 and MMP-9 and of specific tissue inhibitors TIMP-1 and TIMP-2 were determined before treatment and for 21 months of therapy. Results. Serum levels of active MMP-2 and MMP-9 and of TIMP-1 and TIMP-2 did not differ during the treatment. The ratio between MMP-9 and MMP-2 was increased at the 15th month compared with the 3rd, 6th, and 9th months, greater at the 18th month than at the 3rd and 6th months, and higher at the 21st than at the 3rd and 6th months. Discussion. Our data indicate that an imbalance between active MMP-9 and active MMP-2 can occur in MS patients after 15 months of Natalizumab therapy; however, they do not support the use of serum active MMP-2 and active MMP-9 and TIMP-1 and TIMP-2 levels as biomarkers for monitoring therapeutic response to Natalizumab.

    Full Text Available The COQ2 gene encodes an essential enzyme for biogenesis, coenzyme Q10 (CoQ10. Recessive mutations in this gene have recently been identified in families with multiple system atrophy (MSA. Moreover, specific heterozygous variants in the COQ2 gene have also been reported to confer susceptibility to sporadic MSA in Japanese cohorts. These findings have suggested the potential usefulness of CoQ10 as a blood-based biomarker for diagnosing MSA. This study measured serum levels of CoQ10 in 18 patients with MSA, 20 patients with Parkinson's disease and 18 control participants. Although differences in total CoQ10 (i.e., total levels of serum CoQ10 and its reduced form among the three groups were not significant, total CoQ10 level corrected by serum cholesterol was significantly lower in the MSA group than in the Control group. Our findings suggest that serum CoQ10 can be used as a biomarker in the diagnosis of MSA and to provide supportive evidence for the hypothesis that decreased levels of CoQ10 in brain tissue lead to an increased risk of MSA.

    Leptin action in peripheral tissues is enabled by an interaction with specific transmembrane receptors. Several of leptin receptor isoforms were identified, including soluble leptin receptor isoform structurally identical to extracellular domain of the the long leptin receptor isoform. The soluble receptor isoform is released to the circulation and acts probably as leptin-binding factor. The aim of our study was to measure serum concentrations of the soluble leptin receptor in patients with anorexia nervosa and in the control group of healthy women. Relationships of soluble leptin receptor levels to body mass index (BMI), body fat content, serum leptin, TNF-alpha and insulin levels were also studied. 16 patients with anorexia nervosa and 16 age-matched lean healthy women were included into the study. All of the subjects were measured and weighed, the body fat content was estimated from the skinfold thickness measurement. The blood for the determination of leptin, soluble leptin receptor and other hormonal parameters was obtained from all subjects after the overnight fasting. BMI, body fat content, serum leptin and insulin levels in patients with anorexia nervosa were significantly lower than in the control group (BMI: 14.98 +/- 2.32 vs. 22.21 +/- 2.48, p anorexia nervosa were significantly higher compared the to control group (24.67 +/- 8.3 U.ml-1 vs. 15.71 +/- 2.79 U.ml-1, p anorexia nervosa were significantly higher in comparison with the healthy subjects. Except of the negative correlation between serum soluble leptin receptor levels and BMI no statistically significant relationships between serum soluble leptin receptor and the rest of parameters studied were found.

    The adipose tissue plays a role in carcinogenesis with the adipokines it generates. Apelin is an anti-obesigenic adipokine, and assumes roles in both vascularization and tumor cell proliferation. The present study aimed to investigate changes in apelin levels, in postmenopausal breast cancer (BC) patients receiving aromatase inhibitors (AIs). Forty early-stage postmenopausal BC patients treated with AIs with no history of chemotherapy administration were included in the study. At the beginning, we measured serum apelin levels in postmenopausal BC patients who were receiving AIs and healthy women of similar age and normal body mass index (BMI) (control group). We evaluated changes in the body composition, serum lipid profile and serum apelin levels at the beginning and the 12th month through anthropometric measurements and bioelectric impedance analysis. Forty subjects with postmenopausal BC had a median age of 57 years (range 44-82)). BC patients exhibited significantly higher apelin levels and body mass index (BMI) scores compared to the control group (p=0.0001, p=0.0001, respectively). The 12th month's measurements indicated reduced apelin levels in 24 patients (60%) and increased apelin levels in 16 patients (40%) compared to the initial figures. With respect to the parameters, the patients with reduced apelin levels had significantly different waist-to-hip ratio (WHR) and fat mass scores compared to those with higher apelin levels (p=0.008, p=0.047, respectively). This study showed that postmenopausal BC patients had high levels of apelin and high BMI scores. This finding suggests that apelin promoted carcinogenesis particularly in obese individuals. The massive and metabolic changes observed in the fat tissues of the postmenopausal BC patients receiving AIs will especially affect the BC-associated outcome.

    Serum and bile tumor markers are under intense scrutiny for the diagnosis of malignant disease. The purpose of our study was to report the usefulness of serum and bile tumor markers for the discrimination between benign and malignant pancreatobiliary diseases. Between March 2010 and May 2013, 95 patients with obstructive jaundice or history of biliary obstruction, were included in the study. During ERCP, bile samples were obtained for measurement of tumor markers CEA, CA19- 9, CA125, CA72-4 and CA242. Serum samples were taken before ERCP for the same measurements. The patients were divided into two groups: patients with malignant disease and patients with benign disease. Serum tumor marker levels were significantly higher in patients with malignant disease. Serum CA242 and CA19-9 exhibited the highest diagnostic accuracy (76.8% and 73.7%, respectively). CA125 and CA72-4 levels in bile samples were significantly higher in patients with malignant disease. Bile CA125, CEA and CA72-4 achieved the best diagnostic accuracy (69, 65 and 65), respectively). The combined detection of CA19-9, CA242 in serum and CA125, CA72-4 in bile along with total bilirubin levels, showed the best diagnostic accuracy (81%). Serum and bile tumor markers, when studied alone, lack the diagnostic yield to discriminate benign from malignant pancreatobiliary diseases. In cases of diagnostic dilemmas the combination of serum and bile markers might be helpful.

    The previous studies suggest that low serum total antioxidant status (TAS) might be related to oxidative stress. To further examine the TAS, we investigated its relation in patients suffering from cardiovascular diseases. Total 39 samples of males and females were collected; age ranged from 18 to 86 years and divided them into two groups. Group I included 30 samples of cardiovascular patients; group 2 included 9 healthy individuals as control group. In group I, patients suffering from Myocardial infarction (Ml) showed low TAS values compared to the patients suffering from angina. The rest of the patients in group I showed TAS value within the reference range (1.3- 1.77 mmoVL). The present study concluded that the TAS value in MI patients is lower than patients suffering from angina pectoris, further it was also concluded that aging and smoking both leads to the decrease in the level of T AS.

    Objective: To investigate the changes of serum NSE levels in patients with acute cerebral hemorrhage and the effect of nimodepine treatment. Methods: Serum neuron specific enolase (NSE) levels were measured with CLIA in 60 patients with cerebral hemorrhage both before and after treatment as well as in 30 controls. Half of the patients (n=30) were treated with nimodepine and the their half were not. Results: In all the 60 patients, serum NSE levels were significantly higher than those in Controls (P<0.01). After treatment, the NSE levels dropped markedly in all the patients. However, the decrease in the patient group treated with nimodepine was significantly higher than that in the patient group treated without nimodepine (P<0.01). Conclusion: Nimodepine treatment is efficient for reducing the serum NSE levels, which may be related to the residual hematoma size. (authors)

    Due to changes of the dietary pattern and life style, cardiovascular diseases like coronary heart disease (CHD) have been increasing in Korea. In this study, the levels of the serum minerals such as Na, Cl, K, Ca, Fe, Zn and Se for 75 patients with CHD and 25 normal persons, who were older than the age of 40, were investigated by instrumental neutron activation analysis. For analytical quality control, the reference materials, INSPQ and Seronorm, were analyzed simultaneously. The relative errors of the analytical values for the reference materials were within 10% of the certified values. The average concentrations of Na, Cl, K, Ca, Fe, Zn and Se in the serum of the male patients were 2,850±260 mg/l, 3,400±310 mg/l, 160±30 mg/l, 80.9±11.7 mg/l, 1.57±0.73 mg/l, 0.094±0.019 mg/l and 0.795±0.163 mg/l, respectively. The concentrations of Na, Cl, K, Ca, Fe, Zn and Se in the serum of the female patients were 2,890±240 mg/l, 3,430±350 mg/l, 169
