AIM To explore the correlation between serum vitamin B12 level and peripheral neuropathy in patients with chronic atrophic gastritis (CAG). METHODS A total of 593 patients diagnosed with chronic gastritis by gastroscopy and pathological examination from September 2013 to September 2016 were selected for this study. The age of these patients ranged within 18- to 75-years-old. Blood pressure, height and weight were measured in each patient, and the body mass index value was calculated. Furthermore, gastric acid, serum gastrin, serum vitamin and serum creatinine tests were performed, and peripheral nerve conduction velocity and Helicobacter pylori (H. pylori) were detected. In addition, the type of gastritis was determined by gastroscopy. The above factors were used as independent variables to analyze chronic gastritis with peripheral neuropathy and vitamin B12 deficiency risk factors, and to analyze the relationship between vitamin B12 levels and peripheral nerve conduction velocity. In addition, in the treatment of CAG on the basis of vitamin B12, patients with peripheral neuropathy were observed. RESULTS Age, H. pylori infection, CAG, vitamin B9 and vitamin B12 were risk factors for the occurrence of peripheral nerve degeneration. Furthermore, CAG and H. pylori infection were risk factors for chronic gastritis associated with vitamin B12 deficiency. Serum vitamin B12 level was positively correlated with sensory nerve conduction velocity in the tibial nerve (R = 0.463). After vitamin B12 supplementation, patients with peripheral neuropathy improved. CONCLUSION Serum vitamin B12 levels in patients with chronic gastritis significantly decreased, and the occurrence of peripheral neuropathy had a certain correlation. CAG and H. pylori infection are risk factors for vitamin B12 deficiency and peripheral neuropathy. When treating CAG, vitamin B12 supplementation can significantly reduce peripheral nervous system lesions. Therefore, the occurrence of peripheral neuropathy

We evaluated serum total bilirubin levels as a predictor for metabolic syndrome (MetS) and investigated the relationship between serum total bilirubin levels and MetS prevalence. This cross-sectional study included 1728 participants over 65 years of age from Eastern China. Anthropometric data, lifestyle information, and previous medical history were collected. We then measured serum levels of fasting blood-glucose, total cholesterol, triglycerides, and total bilirubin, as well as alanine aminotransferase activity. The prevalence of MetS and each of its individual component were calculated per quartile of total bilirubin level. Logistic regression was used to assess the correlation between serum total bilirubin levels and MetS. Total bilirubin level in the women who did not have MetS was significantly higher than in those who had MetS (Pbilirubin quartiles were linearly and negatively correlated with MetS prevalence and hypertriglyceridemia (HTG) in females (Pbilirubin was an independent predictor of MetS for females (OR: 0.910, 95%CI: 0.863-0.960; P=0.001). The present study suggests that physiological levels of serum total bilirubin might be an independent risk factor for aged Chinese women, and the prevalence of MetS and HTG are negatively correlated to serum total bilirubin levels.

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.

Objective: To explore the relationship between serum 25-hydroxyvitamin D levels and core symptoms of autism spectrum disorder (ASD) in children. Method: In this cross-sectional study, ASD children 4 to 6 years of age who were diagnosed in Department of Developmental and Behavioral Pediatrics, First Hospital of Jilin university from January to May 2017 were assigned to ASD group, and children for routine growth and development assessment in Jilin province were assigned to control group. The two groups were well matched for age and sex, and none of them had received vitamin D supplementation. Serum 25-hydroxyvitamin D levels were measured by HPLC-MS/MS method. The patients of the ASD group were assessed with autism behavior checklist (ABC), childhood autism rating scale (CARS), social response scale (SRS), and autism treatment evaluation checklist (ATEC). The levels of vitamin D were divided into normal(>0.03 ng/L), insufficient (0.01-0.03 ng/L) and deficient (<0.01 ng/L). Levels of serum vitamin D between the two groups were compared by two independent sample t -test, and the difference in the percentages of normal, insufficient and deficient levels of vitamin D was tested by chi-square test, and correlations between vitamin D levels and the total scores or subscales of ABC, CARS, SRS and ATEC were analyzed by Pearson correlation analysis. Result: The 87 subjects in the ASD group included 75 males and 12 females, with a mean (±SD) age of (4.7±0.7) years. The 301 subjects in the control group included 249 males and 52 females, with a mean (±SD) age of (4.8±0.8) years. Serum vitamin D level in ASD children was significantly lower than that of the control group ( (0.021±0.008) vs . (0.036±0.016) ng/L, t= -8.17, P< 0.01), and the between-group percentage difference of normal, insufficient and deficient levels of vitamin D was statistically significant (12 (14%) vs . 186 (62%) , 67 (77%) vs . 113 (37%) , 8 (9%) vs . 2 (1%) , χ(2)=72.1, P< 0.01).

The serum levels of ascorbic acid (ASA), total cholesterol, HDL cholesterol and triglyceride were estimated in 82 healthy persons who consisted of 41 men aged 18 to 69 and 41 women aged 32 to 69. None of fasting lipid profils correlated with the serum level of ASA in total subjects. In young men aged 18 to 23, however, there was significant negative correlation between ASA and total cholesterol. These findings suggest that ASA may be one of effective drug to decrease the level of cholesterol.

Objective: To study the changes and correlations of serum levels of triglyeride (TG), leptin, L -1, neuropeptide Y (NPY) and adiponectin in patients with hypertriglyceridemia (HTG). Methods: Serum levels of TG, leptin, L-1, NPY and adiponectin in 54 patients with HTG and 55 controls were measured with radioimmunoassay (RIA). Results: The serum levels of TG, Leptin, L -1 and NPY in patients with HTG [ (3.46 ± 1.14) mmol/L, (10.56 ±3.79) μg/L, (0.40 ± 0.18) μg/L, (115.89 ± 24.56) μg/L, respectively] were significantly higher than those in controls [ (1.26 ± 0.30) mmol/L, (5.66 ± 2.01) μg/L, (0.22 ± 0.09) μg/L, (95.21 ± 16.85) μg/L, respectively] P < 0.01 in all. But serum levels of adiponectin in patients with HTG (8.98 ± 3.51μg/L) was significantly lower than those in controls [(13.21 ± 9.46) μg/L, P < 0.01]. There were significantly positive correlations between serum TG levels and serum levels of leptin (r = 0.576, P < 0.05). There were also significantly positive correlations between serum leptin levels and serum levels of L-1 and NPY (r = 0.582; r = 0.479, respectively, P < 0.05). Conclusion: There was close relationship between increase in serum TG level and changes of serum levels of leptin, L-1, NPY, adiponectin. Neural-endocrine-immune system participated in fatty metabolism and could result in HTG. (authors)

Objective: To investigate the correlation between serum vascular endothelial growth factor(VEGF) level and CT perfusion parameters in patients with primary liver cancer (PLC) pre-and post-transcatheter arterial chemoembolization (TACE) treatment. Methods: Serum VEGF level was measured and CT perfusion imaging was performed 1 day before and 6 ∼ 8, 32 ∼ 40 days after TACE in 18 patients with PLC. Before and after TACE, the serum VEGF level, the tumor's artery liver perfusion (ALP), the portal vein perfusion (PVP) and the hepatic artery perfusion index (HPI) were measured pre-and post-TACE. The pre-TACE and post-TACE results were compared and statistically analyzed. Results: Based on the therapeutic results, the patients were divided into complete response (CR) group and partial response or stable disease(PR+SD) group. Although no significant difference in serum VEGF level, tumor's ALP, PVP and HPI existed between two groups pre-TACE, there was significant difference in ALP, HPI 6-8 days after TACE (P<0.05). Significant difference in serum VEGF level also existed in CR group (P<0.05), but not in (PR+SD) group, at (32-40) days post-TACE (P=0.221). The serum VEGF level carried a positive correlation with the tumor's ALP and HPI. Conclusion: The serum VEGF level can indirectly reflect the neovascularization of the tumor, while the CTPI can directly and quantitatively reflect the hemodynamic changes of the tumor post-TACE. Moreover, a positive correlation exists between serum VEGF level and ALP, HPI. Therefore, the determination of serum VEGF level together with CTPI is very useful in both evaluating TACE efficacy and making therapeutic schedule. (authors)

Full Text Available PURPOSE: To evaluate alanine aminotransferase levels before and after a hemodialysis session and to correlate these values with the hematocrit rate and weight loss during hemodialysis. PATIENTS AND METHODS: The serum alanine aminotransferase levels, hematocrit rate and body weight were measured and correlated before and after a single hemodialysis session for 146 patients with chronic renal failure. An receiver operating characteristic (ROC curve for the serum alanine aminotransferase levels collected before and after hemodialysis was plotted to identify hepatitis C virus-infected patients. RESULTS: The mean weight loss of the 146 patients during hemodialysis was 5.3% (p < 0.001. The mean alanine aminotransferase levels before and after hemodialysis were 18.8 and 23.9 IU/, respectively, denoting a significant 28.1% increase. An equally significant increase of 16.4% in the hematocrit rate also occurred after hemodialysis. The weight loss was inversely correlated with the rise in both the alanine aminotransferase level (r = 0.3; p < 0.001 and hematocrit rate (r = 0.5; p < 0.001. A direct correlation was found between the rise in alanine aminotransferase levels and the hematocrit during the hemodialysis session (r = 0.4; p < 0.001. Based on the ROC curve, the upper limit of the normal alanine aminotransferase level should be reduced by 40% relative to the upper limit of normal if the blood samples are collected before the hemodialysis session or by 60% if blood samples are collected after the session. CONCLUSION: In the present study, significant elevations in the serum alanine aminotransferase levels and hematocrit rates occurred in parallel to a reduction in body weight after the hemodialysis session. These findings suggest that one of the factors for low alanine aminotransferase levels prior to hemodialysis could be hemodilution in patients with chronic renal failure.

Full Text Available Carcinoembryonic antigen (CEA–targeted imaging and therapeutic agents are being tested in clinical trials. If CEA overexpression in malignant tissue corresponds with elevated serum CEA, serum CEA could assist in selecting patients who may benefit from CEA-targeted agents. This study aims to assess the relationship between serum CEA and CEA expression in pancreatic (n = 20 and rectal cancer tissues (n = 35 using histopathology. According to local laboratory standards, a serum CEA >3 ng/mL was considered elevated. In pancreatic cancer patients a significant correlation between serum CEA and percentage of CEA-expressing tumor cells was observed ( P  = .04, ρ = .47. All 6 patients with homogeneous CEA expression in the tumor had a serum CEA >3 ng/mL. Most rectal cancer tissues (32/35 showed homogeneous CEA expression, independent of serum CEA levels. This study suggests that selection of pancreatic cancer patients for CEA-targeted agents via serum CEA appears adequate. For selection of rectal cancer patients, serum CEA levels are not informative.

Objective: To explore the relationship between serum C-reactive protein (CRP), adiponectin (APN), leptin (Leptin) levels, insulin resistance index (HOMA-IR) and type 2 diabetes mellitus (T2DM) disease susceptibility. Methods: The plasma leptin and insulin (FINS) levels in the DM patients were determined by RIA, and the serum ANP levels were determined by ELSIA. The CRP, conventional serum fasting plasma glucose (FPG) levels were determine by automatic biochemistry analyzer. The insulin resistance index (HOMA-IR, FPG x FINS/22.5) was calculated. The result was analyzed with normal healthy control group. Results: The serum CRP and leptin, HOMA-IR levels in T2DM group were significantly higher than that of in control group (P< 0.01), and the serum ANP was significantly lower than in control group (P<0.01). The HOMA-IR in T2DM was positively correlated with serum CRP (r= 0.36, P<0.05) and leptin(r= 0.39, P<0.05), and was negatively correlated with serum APN (r=0.32, P<0.05). Conclusion: The high serum CRP and leptin and low APN levels hyperlipidaemia might be factors for diabetes, and their metabolic disorders may be closely related with insulin resistance in patients with type 2 diabetes.

Some of the excitatory neurotransmitters including glutamate have been suggested to be involved in headache pathophysiology. To our knowledge, there is a lack of publication about flunarizine efficacy in chronic tension-type headache (CTTH) treatments and the roles of glutamate in CTTH pathophysiology. This study aimed to investigate the flunarizine effect on serum levels of glutamate and its correlation with headache intensity based on the Numeric Rating Scale for pain (NRS) scores in CTTH patients. In a prospective randomised, double-blind study with pre and post-test design, seventy-three CTTH patients were randomly allocated with flunarizine 5 mg, flunarizine 10 mg and amitriptyline 12.5 mg groups. The serum levels of glutamate and NRS scores were measured before and after 15-day treatment. Flunarizine 5 mg was more effective than flunarizine 10 mg and amitriptyline 12.5 mg in reducing serum glutamate levels, whereas amitriptyline 12.5 mg was the most effective in reducing headache intensity. There was found nonsignificant, but very weak negative correlation between headache intensity and serum glutamate levels after flunarizine 5 mg administration (r = -0.062; P = 0.385), nonsignificant very weak negative correlation after flunarizine 10 mg administration (r = -0.007; P = 0.488) and there was found a significant moderate positive correlation (r = 0.508; P = 0.007) between headache intensity and serum glutamate levels after amitriptyline 12.5 mg administration. Since there was no significant correlation found between serum glutamate and headache intensity after treatment with flunarizine, it is suggested that decreasing of headache intensity after flunarizine treatment occurred not through glutamate pathways in CTTH patients.

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.

This study was designed to assess the relationship between serum levels of anti-Müllerian hormone and 25-hydroxy vitamin D in chronic kidney disease male patients. For that, serum 25-hydroxy vitamin D and anti-Müllerian hormone along with follicle-stimulating hormone, luteinising hormone, prolactin, total testosterone and estradiol were assayed in 59 patients with different stages of chronic kidney disease and 21 healthy participants. Compared to controls, serum levels of anti-Müllerian hormone and 25-hydroxy vitamin D were significantly decreased in patients with chronic kidney disease. The decreased anti-Müllerian hormone level correlated positively with estimated glomerular filtration rate and serum levels of testosterone and 25-hydroxy vitamin D. Meanwhile, it was negatively correlated with age and serum levels of urea, creatinine, follicle-stimulating hormone, luteinising hormone and prolactin. 25-Hydroxy vitamin D and luteinising hormone explained the 65.9% variability of anti-Müllerian hormone in a multiple linear regression model. However, anti-Müllerian hormone in crude correlation was more strongly associated with serum 25-hydroxy vitamin D than luteinising hormone. In conclusion, serum level of 25-hydroxy vitamin D might be a determinant factor of anti-Müllerian hormone level, and their relationship might explain in part the dysfunction of Sertoli cells and the impaired testicular functions in chronic kidney disease male patients. © 2018 Blackwell Verlag GmbH.

Objective: To explore the dynamic of tumor necrosis factor-alpha (TNF-α)and its correlation with insulin resistance (IR)during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and 31 cases of normal pregnant women nonnal glucose tolerance, NGT were enrolled in the study, serum TNF-α and insulin were determined by radioimmunoassay. The plasma glucose was measured by using glucose oxidase. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29-32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model of assessment for insulin resistance index (HOMA-IR). Results: (1)Serum TNF-α levels in CDM and NGT group rose with gestational age, and both significantly decreased at postpartum. (2) Serum TNF-α levels in GDM of above-mentioned four stages respectively were (7.05±0.67) ng/L, (7.11± 0.75) ng/L, (7.36±0.79) ng/L, (5.46±0.37) ng/L respectively. All significantly increased than those in the same stage group (t=7.81, 7.05, 7.15, P<0.01). (3) Maternal serum TNF-α levels were in positive correlation with HOMA-IR in GDM (r=0.571, P<0.05). Conclusions: Serum TNF-α levels in GDM rose with gestational age, but significantly decreased at postpartum. The dynamic changes of serum TNF-α contribute to occurrence of insulin resistance.

Full Text Available BACKGROUND: Liver fatty acid-binding protein (FABP1 plays an inconclusive role in adiposity. We investigated the association of serum FABP1 levels with obesity and insulin resistance in Chinese young people under 30 years old. METHODOLOGY AND PRINCIPAL FINDINGS: Cross-sectional analysis including 200 obese and 172 normal-weight subjects matched for age and sex, anthropometric measurements were performed and serum FABP1 and biochemical characteristics were measured. Insulin resistance was determined by homeostasis model assessment of insulin resistance (HOMA-IR and by the insulin sensitivity index (S(i derived from Bergman's minimal model. FABP1 levels in obese subjects were significantly higher than those in normal-weight subjects (p<0.001 and the significance remained after adjustment for age, gender, alanine and aspartate aminotransferases (p<0.001. Serum FABP1 levels were significantly correlated with many metabolic-related parameters, with BMI and triglycerides as the independent determinants. FABP1 levels remained an independent risk factor of insulin resistance assessed by binary S(i (OR = 1.868 per SD unit, 95% CI [1.035-3.373], p = 0.038 after adjustment for age, sex, BMI, waist circumference, systolic blood pressure, serum triacylglycerol, total cholesterol, HDL- and LDL-cholesterol,. FABP1 levels were also elevated with an increasing number of components of the metabolic syndrome (p for trend <0.001. Multiple regression modeling for the MetS and its components demonstrated that hypertriglyceridemia and low HDL-cholesterol were significantly correlated to serum FABP1 levels. CONCLUSIONS AND SIGNIFICANCE: Serum FABP1 correlates positively with obesity and insulin resistance in Chinese young adults. Our data supports the fact that FABP1 might be an important mediator participating in fatty acid metabolism and energy balance.

To investigate the associations of serum α-Klotho and β-Klotho levels with type 2 diabetes mellitus (T2DM) progression. We evaluated 106 healthy controls and 261 cases of T2DM with or without diabetic complications (range: 45-84years). Serum α-Klotho and β-Klotho levels were analyzed using enzyme-linked immunosorbent assays. Compared to the healthy controls, α-Klotho and β-Klotho levels were significantly lower among patients with T2DM and with or without diabetic complications (Pdiabetes, and the positive correlation of α-Klotho and β-Klotho levels indicates that they might have similar mechanisms in T2DM.

Full Text Available Background: Despite a high prevalence of endometriosis, there still exist many challenges indiagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methodsby measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondaryaim is to determine the correlation between these markers with the stage of disease as well as therelationship of the two markers with each other.Materials and Methods: This is a cross-sectional study of 60 women who underwent laparoscopyfor benign conditions. Based on laparoscopic findings and biopsy results, patients were divided to twogroups; one group included patients with pelvic endometriosis (35 patients and the second enrolledpatients free from endometriosis (25 patients. Serum and peritoneal fluid specimens were provided at thetime of laparoscopy and CA125 levels were then assessed by electrochemiluminescence immunoassay.Results: Mean serum and peritoneal fluid CA125 levels were significantly higher in women withendometriosis as compared to the control group (26.42 ± 24.34 IU/ml versus 12.64 ± 6.87 IU/mlin serum and 2203.54 + 993.19 IU/ml versus 1583.42 ± 912.51 IU/ml in peritoneal fluid, p<0.05.CA 125 levels also varied proportionally with the stage of endometriosis; but showed a significantdifference only in higher stages of the disease, both in serum and peritoneal fluid. We calculatedthe cut-off value suggesting a diagnosis of pelvic endometriosis as 14.70 IU/ml for serum and1286.5 IU/ml for peritoneal fluid CA125. A linear correlation between CA 125 levels in serum andperitoneal fluid in patients with pelvic endometriosis has also been observed.Conclusion: Serum and peritoneal fluid CA 125 levels are simple and non-surgical tools fordiagnosing and staging pelvic endometriosis. These markers are of greater diagnostic value inhigher stages of the disease.

Full Text Available Objectives Leptin, is a fat tissue hormone which effects energy expenditure , food intake , hematopoiesis, osteogenesis, angiogenesis, reproductive and immune systems. We aimed to determine serum leptin levels and investigate the association between disease activity and other parameters in RA patients. Methods Patients with RA (n=106 as the study group, healthy controls (n=52 and osteoarthritis (OA patients (n=37 as a control group were enrolled to the study. RA patients were categorized in four different groups according to DAS28 scores: remission ,low (LDA, moderate (MDA or high (HDA disease activity . Results No differences were present between the body mass indices of the three groups. Mean leptin levels in RA patients, OA group and healthy individuals were 25,60±13,41, 23,03±11,51 and 23,81±12,85 ng/ml, respectively and no significant difference was present between the groups. Nine of (8,5% RA patients were in remission, 16 (15,1% were in LDA, 40 (37,7% in MDA and 41 (38,7% were in HDA. Leptin levels did not correlate with DAS28 scores of RA patients (r=-0,12, p=0,11. Mean leptin levels in RA patients with remission was 32,65±7, 28 in LDA 23,94±10,94 in MDA 26,73±14,92 and in HDA 23,59±13,50 ng/ml (p=NS. No associations were observed between leptin levels and CRP, ESR, RF positivity and disease duration. Conclusions Our study revealed no correlation of disease activity and serum leptin levels. Therefore leptin does not seem to be an appropriate biomarker to monitorize inflammation in RA.

Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P = 0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.

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

Full Text Available Introduction & Objective: Several studies have been performed to evaluate correlation of serum high sensitivity CRP (hs-CRP level with the prognosis of the patients with diagnosis of unstable angina, and by now different results were reported. The aim of this study was to assess correlation between serum hs-CRP level and inhospital prognosis and cardiac events in the patients with unstable angina. Materials & Methods: This descriptive analytic study was performed from Sep 2004 till Feb 2006 in Shahid Beheshti hospital. Kermanshah, Iran. Sera were collected from 250 patients for hs-CRP measurement. Exclusion criteria were: acute ST elevation MI, non ST elevation MI, patients with history of recent infection, patients with recent trauma and patients with serum high sensitive CRP level more than 10 mg/lit. Patients were divided into two groups, first group whose serum hs-CRP level was less than 3 mg/lit and second group whose serum hs-CRP level was between 3 and 10 mg/lit. They were followed for recurrent chest pain, arrhythmias, pulmonary edema, acute myocardial infarction and in hospital death. Results were analyzed using x² and t-test. Results: Mean age were 57±7.8 and 58±11.5 years in first group and second group respectively. There was statistically significant difference in some cardiac complications such as dyspnea, duration of hospitalization, recurrent chest pain, CCU admission (p<0.001 and in hospital myocardial infarction (p=0.03, between two groups. Some complications did not have significant difference such as pulmonary edema, cardiogenic shock, arrhythmia, S3, S4 and pulmonary rates .There was no mortality in both groups. Conclusion: According to the results, we can use serum hs-CRP level for risk stratification in the patients with diagnosis of unstable angina. Obviously the patients with high serum hs-CRP level need more attention whether early invasive management help these patients, may be the matter of later studies.

This study examined the changes of serum levels of interleukin (IL)-16, IL-18 and immunoglobulins and the correlation of serum IL-16, IL-18 levels and immunoglobulins in children with asthma and aimed to explore the role of IL-16, IL-18 and immunoglobulins in the pathogenesis of asthma. Thirty-four children with asthma and 21 age and gender-matched healthy children were enrolled in this study. The levels of IL-16, IL-18 and immunoglobulin E (IgE) were determined using ELISA. Immunoglobulin G (IgG), immunoglobulin M (IgM) and immunoglobulin A (IgA) were detected by immunoturbidimetry. The levels of IL-16, IL-18 and IgE in patients with asthma at both acute attack and convalescence stages were significantly higher than those in healthy controls. An increased IgG and a decreased IgA levels were found in asthmatic patients at the acute attack stage. There was a positive correlation between the IL-16 and IL-18 levels at both acute attack and convalescence stages of asthma (r=0.70, P attack stage of asthma (r=0.624, P asthma. The immunologic imbalance exists in children with asthma at both acute attack and convalescence stages. Anti-allergic therapy should be administered through the acute attack to the convalescence stages of asthma.

Benign paroxysmal positional vertigo (BPPV) is a frequently encountered condition that can severely affect the quality of life. In this study, we aimed to assess the possible relations between serum uric acid (SUA) levels and BPPV. Fifty patients with BPPV, and 40 age- and sex-matched control subjects were enrolled in the study. All the patients and controls underwent a complete audio-vestibular test battery including the Dix-Hallpike maneuver and supine roll test for posterior semicircular canal (PSC) and horizontal semicircular canal, respectively. Routine hematological and biochemical analyses were performed in both groups. In the BPPV group, measurements of SUA levels were repeated 1 month after the vertigo attack. The lipid profiles and SUA levels were higher in patients with BPPV than detected in controls (P multiple logistic regression models (P decrement in SUA level 1 month after the vertigo attack compared with the values obtained during the attack (P 0.05). Elevated SUA is positively correlated with BPPV, requiring further efforts to clarify the exact mechanism. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

Full Text Available Abstract Objective: To explore the correlation between Th1 and Th2 cells and the levels of serum matrix metalloproteinase-2 (MMP-2 and MMP-9 in children with asthma. Methods: A total of 89 children with asthma were divided into acute group (n=48 and chronic group (n=41 according to the course of disease, and 40 healthy children at the same term were collected as control group. The ratios of Th1 and Th2 cells as well as levels of MMP-2 and MMP-9 were compared in three groups, and the correlation between Th1 and Th2 cells and levels of MMP-2, MMP-9 was analyzed in acute group and chronic group. Results: When compared with control group, the ratios of Th1 and Th2 cells went down in both acute group and chronic group (P<0.01, while the levels of serum MMP-2 and MMP-9 up (P<0.01. The levels of serum MMP-2 and MMP-9 in acute group were dramatically higher than those in chronic group, and there was statistical significance (P<0.01. Pearson correlation analysis revealed that there was no significant correlation between Th1 and Th2 cells and MMP-2 level (r=0.148, P=0.314, r=0.299, P=0.058; r=0.183, P=0.214, r=0.289, P=0.067, whereas both Th1 and Th2 cells were negatively correlated with MMP-9 level in acute group and chronic group (r=-0.489, P=0.000, r=-0.324, P=0.039; r=-0.352, P=0.014, r=-0.357, P=0.022. Conclusion: Aberrant secretion of Th cells can not only damage the immune function of children with asthma, but also decrease the level of serum MMP-9, consequently affecting the collagen degradation and airway remodeling.

OBJECTIVES: To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD: Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obtained before surgery and 12 hours postoperatively to examine the total antioxidant status, total oxidant status, paraoxonase, stimulated paraoxonase, arylesterase, catalase, myeloperoxidase, ceruloplasmin, oxidative stress markers (advanced oxidized protein products and total thiol level) and ischemia-modified albumin. Surgical specimens were also evaluated. RESULTS: The diagnoses were acute appendicitis (n = 37), perforated appendicitis (n = 8), phlegmonous appendicitis (n = 12), perforated+phlegmonous appendicitis (n = 4), or no appendicitis (n = 4). The Alvarado score of the acute appendicitis group was significantly lower than that of the perforated+phlegmonous appendicitis group (p = 0.004). The serum total antioxidant status, total thiol level, advanced oxidized protein products, total oxidant status, catalase, arylesterase, and ischemia-modified albumin levels were significantly different between the acute appendicitis and control groups. There was no correlation between the pathological extent of acute appendicitis and the tissue levels of the markers; additionally, there was no correlation between the tissue and serum levels of any of the parameters. CONCLUSIONS: The imbalance of oxidant/antioxidant systems plays a role in the pathogenesis acute appendicitis. The Alvarado score can successfully predict the presence and extent of acute appendicitis. PMID:25518019

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.

To determine whether weighting improves the correlation of ultrasound (US) score with serum matrix metalloproteinase-3 (MMP-3) level in rheumatoid arthritis (RA). As ultrasound examination was performed on 100 RA patients, and the severity of synovial effusion and synovial hypertrophy and the blood flow were semi-quantitatively graded from 0 to 3 by using the gray-scale (GS) and power Doppler (PD) modes. We then calculated the sums of the scores of the 28 joints of each patient in the 2 modes, that is, the GS28 and PD28 scores, as well as the respective scores weighted using the Lansbury articular index (LAI, shoulder and elbow, × 12; wrist, × 8; and knee, × 24)-Lans GS28 and Lans PD28 scores. The Lans PD28 score showed a higher correlation with MMP-3 (r = 0.591; 95% confidence interval, 0.446-0.705, p correlated well with the serum MMP-3 level. Weighting with the LAI can improve the correlation of US findings with serum MMP-3 level. Bidirectional approach based on both serum MMP-3 level and US scores can further improve the assessment of disease activity in RA patients.

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.

Hypovitaminosis D has been identified as a possible new cardiovascular risk factor. However, the results of studies correlating serum vitamin D levels with markers of subclinical atherosclerosis have been conflicting. The aim of this study was to correlate serum levels of 25-hydroxyvitamin D [25(OH)D] with carotid intima-media thickness (C-IMT) and conventional cardiovascular risk factors in Afro-descendants. A cross-sectional analysis was performed on a sample of 382 individuals from a cohort of descendants of African slaves, inhabitants of "Quilombola" communities, with a mean age of 57.79 ±15.3 years, 54.5% of whom were women. Socio-demographic and clinical data were collected and biochemical tests were performed, including serum levels of 25(OH)D by electrochemiluminescence and urinary albumin excretion, evaluated by the albumin/creatinine ratio (ACR) in a spot urine sample. All participants underwent high-resolution ultrasonography for C-IMT measurement. Hypovitaminosis D was defined as serum 25(OH)D levels <30 ng/mL. The mean serum 25(OH)D levels were 50.4±13.5 ng/mL, with a low prevalence of hypovitaminosis D (4.86%). By simple linear correlation, a significant inverse association between 25(OH)D levels and C-IMT (r=-0.174, P=0.001) was observed. However, after multiple linear regression analysis, the significance of the association between serum levels of 25(OH)D and C-IMT measurement was lost (β=-0.039, P=0.318) and only male gender, age, smoking, systolic blood pressure, glucose and low density lipoprotein (LDL)-cholesterol remained significantly associated with C-IMT. Levels of 25(OH)D were independently and positively associated with HDL-cholesterol and inversely associated with age and ACR. In conclusion, no independent association between 25(OH)D levels and C-IMT was observed in this population. On the other hand, there was an inverse association with albuminuria, a marker of endothelial lesion.

Objective: To investigate the effect of different status of thyroid function (hypothyroidism and hyperthyroidism as well as euthyroid status) on serum ghrelin and leptin levels. Methods: The levels of serum ghrelin and leptin were determined by radio immunoassay in 46 untreated subjects with hyperthyroidism, 15 hyperthyroid patients achieved a euthyroid status after radioiodine 131 I therapy, 21 cases of hypothyroidism and 18 cases of normal controls, respectively. Meanwhile, the serum levels of free triiodothyronine (FT 3 ), free thyroxine (FT 4 ) and thyroid-stimulating hormone (TSH) were measured by chemiluminescence immune assay. Results: (1) The levels of serum ghrelin in untreated hyperthyroidism were significantly lower than those in hyperthyroid patients achieved a euthyroid status (t=3.21, P 3 (r=-0.29, P 4 (r=-0.26, P< 0.05), positively correlated with serum TSH (r=0.36, P<0.05); serum leptin levels did not correlate with thyroid hormone. Conclusion: The levels of serum ghrelin were differently under different thyroid functional status and correlated with thyroid hormone, while serum leptin were not. (authors)

Objective: Neutrophil gelatinase-associated lipocalin (NGAL) is a novel inflammatory marker that is released from neutrophils. In this study, we evaluated the correlation between serum NGAL level and clinical and angiographic risk scores in patients diagnosed with non-ST elevation acute coronary syndrome (NSTE-ACS). Methods: Forty-seven random NSTE-ACS patients and 45 patients with normal coronary arteries (NCA) who underwent coronary angiography were enrolled in the study. GRACE risk score and SYNTAX and Gensini risk scores were used, respectively, for the purpose of clinical risk assessment and angiographic risk scoring. Serum NGAL level was measured via ELISA in peripheral blood samples obtained from the patients at the time of admission. Results: Serum NGAL level was significantly higher in the NSTE-ACS group compared to the control group (112.3±49.6 ng/mL vs. 58.1±24.3 ng/mL, p22) group had statistically significantly higher serum NGAL levels compared to the low SYNTAX (≤22) group (143±29.5 ng/mL vs. 98.7±43.2 ng/mL, p=0.001). Conclusion: NGAL level was positively correlated with lesion complexity and severity of coronary artery disease in patients with NSTE-ACS. Serum NGAL levels on admission are associated with increased burden of atherosclerosis in patients with NSTE-ACS. PMID:25430410

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.

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.

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 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.

The elucidation of the changes of fetuin-A in the context of bariatric surgery. Twenty obese patients (8 males, 12 females; body mass index = 42.5±3.4 kg/m2) were studied at baseline and 6 months after bariatric surgery. Serum fetuin-A levels did not differ with regard to the presence of each individual component of the Metabolic Syndrome (MetS) at baseline, except for hypertriglyceridaemia [increased serum fetuin-A levels (p=0.011)]. Circulating fetuin-A was positively correlated with serum triglycerides (TG) (r=0.461, p=0.047) and negatively correlated with serum globulins (r=-0.477, p=0.033) and C-reactive protein (CRP) (r=-0.604, p=0.010), while it independently predicted TG at baseline. Circulating fetuin-A did not change during the 6 months either in the whole population or in the subgroups of patients who were positive for each individual component of MetS at baseline and negative for this component at 6 months of follow-up, except for hypertriglyceridaemia [reduction of serum fetuin-A levels (p=0.046)]. The subgroup of patients with a decrease in circulating fetuin-A during the 6 months was characterized by a smaller reduction of serum globulins (p=0.003) and CRP (p=0.049). The change in serum fetuin-A levels over the 6 months was positively correlated with the change in TG (r=0.592, p=0.006) and negatively correlated with the change in serum globulins (r=-0.523, p=0.018) and CRP (r=-.494, p=0.037). Circulating fetuin-A predicted serum triglycerides before as well as 6 months after bariatric surgery.

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 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

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.

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.

C-reactive protein concentration has continuous associations with risk of coronary artery disease, ischemic stroke and death from several cancers. In addition, several studies have shown that CRP could be used to predict first ever myocardial infarction and stroke in healthy subjects, as well as outcome in acute setting. High levels of another biomarker, D-dimer, have been found to be independently associated with occurrence of coronary events. Methods: This correlational study was carried out at the Department of Cardiology, Ayub Teaching Hospital Abbottabad, in collaboration with the department of Biochemistry Postgraduate Medical Institute Lahore from 15th July 2013 to 15th May 2014. Patients aged 30 years or more of either gender having coronary artery disease was included in the study. Their serum D-dimer levels and C-reactive protein levels were measured for correlation with coronary artery disease. Results: A total of 50 patients of CAD were included in this study. Out of these 30 (60 percent) were males and 20 (40 percent) were females. Elevated CRP levels and D-dimer levels were noted in all of these patients. Pearson correlation coefficient test was performed on both CRP and D-dimer levels. Pearson correlation coefficient was calculated to be r= -0.1522 and when a p value was calculated, it was found to be 0.292 which implied that the results were not significant. Conclusion: This study showed that there is no correlation between CRP levels and D-dimer levels in patients with Coronary Artery Disease. (author)

Full Text Available BACKGROUND In our study, 50 cases of transurethral prostate biopsies were evaluated histopathologically in the Department of Pathology in collaboration with Department of Urology, Regional Institute of Medical Sciences, Imphal, from October 2013 to September 2015. Total PSA (tPSA was estimated from serum samples in all cases. MATERIALS AND METHODS A total of 50 patients with elevated serum tPSA levels were inducted in this study and prostate needle biopsies taken. Matched prostatectomy specimens were also obtained for 7 cases. Specimens were kept in 10% formalin saline, grossing done and tissues processed. H and E stained sections were examined and the different histomorphological features noted. Gleason scoring system was used in cancers to stratify it. RESULTS Out of the 50 cases, 30 malignant (all adenocarcinomas, 4 premalignant and 16 benign cases were found. Gleason scoring on needle biopsies were compared against the prostatectomy specimens. In 5 carcinoma cases with Gleason score 3+3=6 on needle biopsy, 4 cases had similar findings in the corresponding prostatectomy specimens, however, it was upgraded in 1 case. Intermediate differentiation prostatic carcinomas with Gleason score 3+4=7 in needle biopsies were comparable with prostatectomy specimens in 2 cases. The differentiation of prostatic carcinoma vis-a-vis Gleason scoring correlated well with the PSA values. In carcinomas, tPSA value and the Gleason score had a very good correlation (rs = 0.908. Mean PSA value was found to increase from benign to premalignant and malignant cases, this was found to be statistically significant (p<0.05. CONCLUSION Use of newer technologies like MRI and serum PSA as a screening tool for prostate pathology have made it possible to identify prostate cancer at an earlier stage in younger age group and has an increased case detection rate. However, there is no marker to predict disease course and at times lead to overtreatment. Image-guided prostate biopsy

Multiple sclerosis (MS) is an inflammatory-demyelinating disease of the central nervous system (CNS). Autoimmune inflammation is common in the early stages of MS and is followed by neurodegenerative processes. The result of these changes is axon and myelin breakdown. The paraclinical examination methods are an important part of the diagnostic process. Magnetic resonance imaging of the brain and the cervical spinal cord and an examination of cerebrospinal fluid (CSF) are common paraclinical examinations. An increasing number of studies deal with CSF and serum levels of biomarkers and their role in MS. We hypothesized that the level of interleukin-8 (IL-8) could be different in MS patients than in controls. These differences may be related to damage of the blood-brain barrier (BBB). BBB damage is quantified by the quotient of albumin (Q-alb). CSF and serum levels of IL-8 were assessed in 102 patients with newly diagnosed MS meeting McDonald's revised diagnostic criteria and in 102 subjects as a control group. We then correlated these results with Q-alb. Levels of IL-8 in CSF were significantly higher in MS patients than in controls (Mann-Whitney U test, p<0.0001). Serum levels of IL-8 were significantly lower in MS patients than in controls (Mann-Whitney U test, p=0.018). Spearman's correlation analysis proved a significant correlation between levels of IL-8 and Q-alb. As the etiology of MS is only partially known, research dealing with biomarkers in MS should continue. Better knowledge of etiology can provide a new perspective, especially for treatment.

Objective: To study the changes of serum leptin, insulin and adiponectin levels and their relationship with BMI in females with simple obesity. Methods: Serum leptin, adiponectin and insulin levels were measured with RIA in 48 pre-obese females (BMI=23-24.9 kg/m 2 ), 40 females with simple obesity, (BMI≥25 kg/m 2 ) and 42 female controls (BMI 18-22.9 kg/m 2 ). Correlations among these variables were studied. Results: Serum leptin, insulin levels were significantly higher and serum adiponectin levels were significantly lower in both the pre-obese and obese females than those in controls. Serum leptin, insulin levels were positively correlated to BMI; Serum adiponectin levels were negatively correlated to BMI. Conclusion: Within normal range of BMI, the leptin-insulin feedback mechanism provided satisfactory self-regulation. However, with excessive BMI, this dynamic equilibrium would be disrupted. The defective equilibrium, together with the abnormal low adiponectin level, would predispose to the development of diabetes mellitus. (authors)

There is strong evidence that alopecia areata is of immunological background; Interleukin-17 (IL-17) is a Th17 pro-inflammatory cytokine that has been allied to the pathogenesis of different autoimmune and inflammatory diseases. This study aimed to measure serum IL-17A in patients with alopecia areata, and to study associations between IL-17A levels and disease severity before and after Narrowband-Ultraviolet B (NB-UVB), patient gender and age. Twenty patients with AA of the scalp were treated with (NB-UVB), and 15 healthy subjects' age and sex matched were enrolled as controls. Patients were assessed clinically by SALT score. Assay of serum levels of IL-17A by ELISA was done in patients and controls. The mean level of IL-17A was (15.63 Â ± 10.89 Pg/mL) in AA patient group, and (16.50 Â ± 5.02 Pg/mL) in control group. No statistically significant correlation was detected between SALT score and IL-17A level before (NB-UVB) treatment while a significant negative correlation between SALT score and IL-17A level was observed after treatment (r = -.448, P = .047). Mean SALT score for patients was (14.03 Â ± 13.48), and correlated positively with age (r = .446, P = .049). Although (NB-UVB) is an immune-modulatory type of treatment for alopecia areata of mild efficacy especially if it's used alone, it has shown significant decrease in serum IL-17A level among patients, and correlation to disease severity. © 2018 Wiley Periodicals, Inc.

Oral squamous cell carcinoma (OSCC) accounts for 90 % of malignant lesions of oral cavity. The study assessed the potential of Cyfra 21-1 as a tumor marker in OSCC. The study included 50 patients of OSCC to evaluate levels of Cyfra 21-1 in serum and saliva by electrochemiluminescent immunoassay (ECLIA) and CK19 messenger RNA (mRNA) expression in tissue by florescent quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) along with healthy individuals as control. The salivary and serum Cyfra 21-1 levels in patients of OSCC were significantly higher compared to controls (p value < 0.01). There was a 2.75-fold increase in CK19 mRNA expression in OSCC cases compared to controls. A significant positive correlation was found between serum and salivary Cyfra 21-1, serum Cyfra 21-1, and CK19 mRNA expression and between salivary Cyfra 21-1 and CK19 mRNA expression. Among these, correlation between serum and salivary Cyfra 21-1 was highly significant. Salivary and serum Cyfra 21-1 showed significantly elevated levels in grade II OSCC compared to grade I histopathologically. Elevated levels of salivary Cyfra 21-1 were associated with recurrence in OSCC patients. Reverse operating curve constructed using 3 ng/ml as a cutoff for serum Cyfra 21-1 revealed the sensitivity and specificity to be 88 and 78.2 %, respectively. Using a cutoff value of 8.5 ng/ml for salivary Cyfra 21-1, the sensitivity was found to be 93.8 % and specificity 84.3 %. We advocate salivary Cyfra 21-1 as a better diagnostic marker over serum Cyfra 21-1 as well as a potential marker in the prognosis of OSCC.

Full text: Determination of the normal values of glomerular filtration rate (GFR) is an essential part of the evaluation of patient with kidney disease. GFR almost linearly decreases with age at a mean annual rate of 0.8 ml/min/1.73 m2 over the age of 30 years old. According to NHANES III mean GFR for population with age > 60 years was 80 mL/min/1.73 m2. It is recommended for each centre to determine their own normal values of GFR for different age groups particularly in geriatric population. Recently, serum cystatin-C has been proposed as a new endogenous marker of glomerular filtration rate. Aim of the study was to determination of normal values of glomerular filtration rate (GFR) in geriatrics in Bandung and its correlation with serum Cystatin-C levels. Subjects were 24 males and 36 females (mean age 66.71 ± 6.7 years; range 60-87 yrs), without any renal and/or systemic disease. Creatinine clearance was estimated by using Cockroft-Gault formula and serum cystatin-C level were determined by using particle enhanced immunonephelometric method, while GFR values were determined by external body counting methods using Tc-99m DTPA ( Gates' methods ). Pearson correlation was used to determine correlation between variables and a P value < 0.05 is considered significant. Results and Discussion. Mean total GFR was 67.57 ml/min/1.73 m2 (SD ± 16.02), range from 45 to 100 ml/min/1.73 m2. Mean total GFR for male was 69.46 ml/min/1.73 m2, and female was 66.31 ml/min/1.73 m2, the difference was statistically significant (p < 0.05). The results were lower than NHANES III values. There was a better correlation between total GFR and cystatin-C level (r = -0.522 and p < 0.001) compared to total GFR and creatinine clearance (r 0.306 and p < 0.005). Mean creatinine clearance was 57.93 ml/min and serum cystatin-C was 0.97 mg/dl, the correlation was statistically significant (r -0.414 and p < 0.005). Conclusions: The normal values of GFR in geriatric population in Bandung were 69

The aim of the study was to evaluate the correlation between serum prostate specific antigen (PSA) level and bone scintigraphy in newly diagnosed untreated prostate cancer patients. The probability of a positive bone scan for metastases was analyzed for different threshold values of prostate specific antigen (PSA), acid phosphastase and alkaline phosphates. Fifty four newly diagnosed untreated prostate cancer patients (mean age, 67 years range, 41 to 94) were included in this study. In each case serum PSA, acid phosphatase and alkaline phosphatase measurements were performed followed by whole body Technetium-99m MDP bone scan. The positive predictive value of serum PSA level for bone metastases at the threshold of 10 ng/ml was 70% whereas the same threshold level of PSA gave a negative predictive value of 100%. We used receiver operating characteristics (ROC) analysis to examine the power of predictive value of each serum test, in predicting the results of the bone scan. We also applied regression analysis for the assessment of correlation between the levels of tumor markers and the extent of bone pathology. It was concluded that bone scintigraphy seems to be unnecessary in evaluation of newly diagnosed untreated prostate cancer in patients with no clinical signs of bone pathology and serum PSA levels of equal to or less than 10 ng/ml.

To determine the relationship between intravoxel incoherent motion (IVIM) imaging derived quantitative metrics and serum soluble CD40 ligand (sCD40L) level in an embolic canine stroke model. A middle cerebral artery occlusion model was established in 24 beagle dogs. Experimental dogs were divided into low- and high-sCD40L group according to serum sCD40L level at 4.5 hours after establishing the model. IVIM imaging was scanned at 4.5 hours after model establishment using 10 b values ranging from 0 to 900 s/mm{sup 2}. Quantitative metrics diffusion coefficient (D), pseudodiffusion coefficient (D{sup *}), and perfusion fraction (f) of ischemic lesions were calculated. Quantitative metrics of ischemic lesions were normalized by contralateral hemisphere using the following formula: normalized D = D{sub stroke} / D{sub contralateral}. Differences in IVIM metrics between the low- and high-sCD40L groups were compared using t test. Pearson's correlation analyses were performed to determine the relationship between IVIM metrics and serum sCD40L level. The high-sCD40L group showed significantly lower f and normalized f values than the low-sCD40L group (f, p < 0.001; normalized f, p < 0.001). There was no significant difference in D{sup *}, normalized D{sup *}, D, or normalized D value between the two groups (All p > 0.05). Both f and normalized f values were negatively correlated with serum sCD40L level (f, r = −0.789, p < 0.001; normalized f, r = −0.823, p < 0.001). However, serum sCD40L level had no significant correlation with D{sup *}, normalized D{sup *}, D, or normalized D (All p > 0.05). The f value derived from IVIM imaging was negatively correlated with serum sCD40L level. f value might serve as a potential imaging biomarker to assess the formation of microvascular thrombosis in hyperacute period of ischemic stroke.

Full Text Available Background : Most atopic dermatitis (AD patients have elevated serum immunoglobulin E (IgE. Impaired folic acid (FA metabolism was found to reduce the intracellular methyl donor pool, associated with a higher prevalence of atopy. Aim : To assess serum IgE and FA in AD patients and to correlate their levels with the disease severity, and with each other. Materials and Methods : Twenty patients with AD were assessed for serum FA and IgE, compared with 20 age- and sex-matched controls. Patients were classified into three groups (mild, moderate, and severe AD based on clinical severity according to Nottingham index. In both patients and controls, serum IgE was measured using Enzyme-linked immunosorbent assay technique and serum FA was measured using Microparticle Enzyme Immunoassay technique. Results : Serum FA levels were lower in AD patients compared with controls, but the difference was not statistically significant. FA levels did not show statistically significant difference among disease severity groups and did not correlate with serum IgE levels. On the other hand, serum IgE levels were significantly elevated in AD patients compared with controls, and among AD patients, its levels were significantly elevated in severe AD compared with mild and moderate disease. Conclusion : Serum IgE is useful in assessment of AD severity and activity. FA contribution to AD needs further investigations.

Diabetic Nephropathy (DN), a serious and prevalent complication of diabetes, has been rapidly raising worldwide. Vaspin, as an adipokine with anti-diabetic effects, is predominantly released from visceral adipose tissue. Moreover, vaspin has the stimulatory effect on nitric oxide (NO) bioavailability through the activation of NO synthase. The aim of the present study was to investigate the serum levels of vaspin and their correlation with NO metabolite in diabetic patients with normal renal function and renal insufficiency. Volunteers patients with non-nephropathy Type 2 Diabetic Mellitus (T2DM) as control (n=40, age= 56.95±6.11 years) and patients with diabetic nephropathy (DN) (n=40, age=57.85±5.63 years) as case group were enrolled in this study, and serum samples were collected for the measurement of vaspin levels by ELISA technique. Also, serum levels of NO metabolites were calorimetrically assessed. We found that vaspin levels significantly decreased in diabetic patients with nephropathic condition as compared with diabetic patients with normal renal function (p diabetic patients with nephropathy in comparison with non-nephropathic diabetics (pdiabetic patients and increased levels of NO may be a defensive mechanism in the DN.

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

Full Text Available The role of inflammation being minimal in the pathogenesis of type 2 diabetes mellitus (T2DM in nonobese patients; the aim of the study was to investigate the role of adenosine deaminase (ADA and see its association with diabetes mellitus. The preliminary case control study comprised of 56 cases and 45 healthy controls which were age and sex matched. 3 mL venous blood samples were obtained from the patients as well as controls after 8–10 hours of fasting. Serum ADA and routine biochemical parameters were analyzed. Serum ADA level was found significantly higher among nonobese T2DM subjects with respect to controls (38.77±14.29 versus 17.02±5.74 U/L; P<0.0001. Serum ADA level showed a significant positive correlation with fasting plasma glucose (r=0.657; P<0.0001 level among nonobese T2DM subjects, but no significant correlation was observed in controls (r=-0.203; P=0.180. However, no correlation was observed between serum ADA level compared to BMI and HbA1c levels. Our study shows higher serum ADA, triglycerides (TG and fasting plasma glucose (FPG levels in nonobese T2DM patients, and a strong correlation between ADA and FPG which suggests an association between ADA and nonobese T2DM subjects.

In this study, serum zinc and lipoprotein concentrations were determined in order to assess the health status of an elderly population residing in Sao Paulo city, SP, Brazil. This population consisted of elderly considered healthy and participating of a 'Successful Ageing' program of the Sao Paulo University Medical School. Fasting blood samples were collected from 87 elderly individuals (63 females and 24 males) aged 60-91 and mean age of 72 +- 7 years. Zn concentrations were determined by neutron activation analysis at the IPEN/CNEN/ SP and, the lipoprotein (HDL, LDL and total cholesterol) concentrations were determined using routine analysis methods of the Central Laboratory Division, Hospital das Clinicas, FMUSP. Results obtained for Zn indicated that all the individuals presented this element within the recommended value. For total cholesterol and HDL-cholesterol concentrations, 96 % of elderly presented levels within the desired range but for LDL cholesterol concentrations only about 70.0 % of individuals were in the desired range. Serum concentration of Zn were positively correlated to LDL-cholesterol levels (correlation coefficient r = 0.21, p < 0.06). Furthermore, the ratios of [HDL-cholesterol] / [LDL-cholesterol] were negatively correlated with Zn concentrations (r = - 0.234, p < 0.04). The positive correlation found between the serum concentrations of Zn and LDL-cholesterol indicates the possible effect of this element in serum lipoprotein profiles. Thus ,these findings suggest that more investigations should be conducted on Zn supplementation in elderly subjects with cardiovascular diseases. (author)

Serum thymus and activation-regulated chemokine (TARC) levels are associated with the disease activity of patients with atopic dermatitis (AD) and sensitively reflect short-term changes in skin conditions. The main treatment for AD is topical agent application. This study investigated the relationship between serum TARC levels and the dosage of topical agents, including corticosteroids and/or tacrolimus, in patients with AD. The serum TARC levels of 56 AD patients and the amounts of topical agents prescribed to them were investigated retrospectively. The weekly reduction in serum TARC levels and weekly dosage of topical agents among AD patients were compared and their associations were evaluated. The dosage of topical agents was closely related to serum TARC levels. One gram of strong rank steroid or the equivalent amount of steroid/tacrolimus is required to reduce serum TARC levels by 9.94 pg/mL weekly in moderate to severe AD patients. Higher initial TARC levels require more topical agent, which results in a more rapid decrease in TARC levels. The serum TARC levels and eosinophil numbers in peripheral blood are significantly correlated. Serum TARC level improvement and topical agent dosage are strongly correlated. TARC and eosinophil numbers are significantly correlated, but the wider range of TARC levels seems to be clinically more useful for monitoring AD severity. The serum TARC level is a very sensitive biomarker for monitoring the severity and treatment response in AD.

The aim of this study was to analyze the correlation of vitamin D levels with clinical parameters, bone mineral density (BMD), quality of life (QoL) and nailfold capillaroscopy (NC) in patients with diffuse systemic sclerosis (SSc). Thirty-eight female patients with diffuse SSc were analyzed regarding 25-hydroxyvitamin D (25OHD) serum levels. At inclusion, organ involvement, autoantibodies, modified Rodnan skin score (mRSS), Medsger Disease Severity Index (MDSI), body mass index (BMI), BMD, NC, Short-Form-36 Questionnaire (SF-36), and Health Assessment Questionnaire (HAQ), were performed through a standardized interview, physical examination and electronic chart review. Mean 25OHD serum level was 20.66±8.20ng/mL. Eleven percent of the patients had 25OHD levels ≤10ng/mL, 50% ≤20ng/mL and 87% ≤30ng/mL. Vitamin D serum levels were positively correlated with BMI (r=0.338, p=0.038), BMD-total femur (r=0.340, p=0.037), BMD-femoral neck (r=0.384, p=0.017), SF-36-Vitality (r=0.385, p=0.017), SF-36-Social Function (r=0.320, p=0.050), SF-36-Emotional Role (r=0.321, p=0.049) and SF-36-Mental Health (r=0.531, p=0.0006) and were negatively correlated with HAQ-Reach (r=-0.328, p=0.044) and HAQ-Grip Strength (r=-0.331, p=0.042). A negative correlation with NC-diffuse devascularization (p=0.029) and NC-avascular area (p=0.033) was also observed. The present study provides novel evidence demonstrating that low levels of 25OHD have a negative impact in diffuse SSc QoL and further studies are needed to define whether vitamin D supplementation can improve health related QoL in these patients. The additional observation of a correlation with severe NC alterations suggests a possible role of 25OHD in the underlying SSc vascular involvement. Copyright © 2016 Elsevier Editora Ltda.

At inclusion, organ involvement, autoantibodies, modified Rodnan skin score (mRSS, Medsger Disease Severity Index (MDSI, body mass index (BMI, BMD, NC, Short-Form-36 Questionnaire (SF-36, and Health Assessment Questionnaire (HAQ, were performed through a standardized interview, physical examination and electronic chart review. Results: Mean 25OHD serum level was 20.66 ± 8.20 ng/mL. Eleven percent of the patients had 25OHD levels ≤10 ng/mL, 50% ≤20 ng/mL and 87% ≤30 ng/mL. Vitamin D serum levels were positively correlated with BMI (r = 0.338, p = 0.038, BMD-total femur (r = 0.340, p = 0.037, BMD-femoral neck (r = 0.384, p = 0.017, SF-36-Vitality (r = 0.385, p = 0.017, SF-36-Social Function (r = 0.320, p = 0.050, SF-36-Emotional Role (r = 0.321, p = 0.049 and SF-36-Mental Health (r = 0.531, p = 0.0006 and were negatively correlated with HAQ-Reach (r = −0.328, p = 0.044 and HAQ-Grip Strength (r = −0.331, p = 0.042. A negative correlation with NC-diffuse devascularization (p = 0.029 and NC-avascular area (p = 0.033 was also observed. Conclusion: The present study provides novel evidence demonstrating that low levels of 25OHD have a negative impact in diffuse SSc QoL and further studies are needed to define whether vitamin D supplementation can improve health related QoL in these patients. The additional observation of a correlation with severe NC alterations suggests a possible role of 25OHD in the underlying SSc vascular involvement.

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

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

In order to evaluate the possible underlying factors for the increase in red cell 2,3-diphosphoglycerate content observed in late diabetic pregnancy, its relationship with serum unconjugated oestriol, human placental lactogen, haemoglobin and hydrogen ion concentrations was investigated in 42 pregnant diabetic women. A significant correlation was found between red cell 2,3-diphosphoglycerate and serum unconjugated oestriol (r = 0.54, p less than 0.001), whereas no correlation was present between 2,3-diphosphoglycerate and the following variables: arterial pH, haemoglobin concentration and human placental lactogen. The content of 2,3-diphosphoglycerate correlated significantly with haemoglobin-oxygen affinity expressed as P50 at pH 7.4 (r = 0.34, p less than 0.05). The results of this study indicate that serum unconjugated oestriol may participate in the regulation of red cell 2,3-diphosphoglycerate content and thereby of the maternal blood oxygen release to the fetus.

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

Objective: To investigate a correlation between serum alkaline phosphatase level and body mass index in human subjects. Methods: The comparative cross-sectional study was carried out at the National Institute for Biotechnology and Genetic Engineering, Faisalabad, Pakistan, from April 2012 to June 2013. Blood serum alkaline phosphatase levels were estimated and the subjects were divided into three sub-groups on the basis of their body mass index: normal weight (<25kg/m2), overweight (25-27kg/m2) and obese (>27kg/m2) subjects. The serum samples were used for the estimation of clinically important biochemical parameters, using commercial kits on clinical chemistry analyser. Results: Of the 197 subjects, 97(49 percent) were obese and 100(51 percent) were non-obese. The serum alkaline phosphatase level increased in obese (214±6.4 IU/L) compared to the non-obese subjects (184.5±5 IU/L). Furthermore, a significant linear relationship (r=0.3;p-0.0001) was found between serum alkaline phosphatase and body mass index. Other biochemical variables were not correlated to the body mass index. Conclusion: Over activity and higher amounts of alkaline phosphatase were linked to the development of obesity. (author)

Full Text Available The serum levels of several metabolites are significantly altered in schizophrenia patients. In this study, we performed a targeted analysis of 34 candidate metabolites in schizophrenia patients (n = 25 and compared them with those in age- and gender-matched healthy subjects (n = 27. Orthogonal partial least square-discriminant analysis revealed that complete separation between controls and patients was achieved based on these metabolites. We found that the levels of γ-glutamylcysteine (γ-GluCys, linoleic acid, arachidonic acid, D-serine, 3-hydroxybutyrate, glutathione (GSH, 5-hydroxytryptamine, threonine, and tyrosine were significantly lower, while D-lactate, tryptophan, kynurenine, and glutamate levels were significantly higher in schizophrenia patients compared to controls. Using receiver operating characteristics (ROC curve analysis, the sensitivity, specificity, and the area under curve of γ-GluCys, a precursor of GSH, and D-lactate, a terminal metabolite of methylglyoxal, were 88.00%, 81.48%, and 0.8874, and 88.00%, 77.78%, and 0.8415, respectively. In addition, serum levels of D-lactate were negatively correlated with γ-GluCys levels in patients, but not in controls. The present results suggest that oxidative stress-induced damage may be involved in the pathogenesis of schizophrenia.

Background and Purpose Bronchial asthma (BA) is a chronic airway disease characterized by airway hyperresponsiveness and remodeling, which are intimately linked to chronic airway inflammation. Reactive oxygen species (ROS) such as hydrogen peroxide are generated by inflammatory cells that are involved in the pathogenesis of BA. However, the role of ROS in the management of BA patients is not yet clear. We attempted to determine the role of ROS as a biomarker in the clinical setting of BA. Subjects and Methods We enrolled patients with BA from 2013 through 2015 and studied the degrees of asthma control, anti-asthma treatment, pulmonary function test results, fractional exhaled nitric oxide (FeNO), serum reactive oxygen metabolite (ROM) levels, and serum levels of interleukin (IL)-6 and IL-8. Results We recruited 110 patients with BA. Serum ROM levels correlated with white blood cell (WBC) count (rs = 0.273, p = 0.004), neutrophil count (rs = 0.235, p = 0.014), CRP (rs = 0.403, p < 0.001), and IL-6 (rs = 0.339, p < 0.001). Serum ROM levels and IL-8 and CRP levels negatively correlated with %FEV1 (rs = -0.240, p = 0.012, rs = -0.362, p < 0.001, rs = -0.197, p = 0.039, respectively). Serum ROM levels were significantly higher in patients who experienced severe exacerbation within 3 months than in patients who did not (339 [302–381] vs. 376 [352–414] CARR U, p < 0.025). Receiver-operating characteristics analysis showed that ROM levels correlated significantly with the occurrence of severe exacerbation (area under the curve: 0.699, 95% CI: 0.597–0.801, p = 0.025). Conclusions Serum levels of ROM were significantly associated with the degrees of airway obstruction, WBC counts, neutrophil counts, IL-6, and severe exacerbations. This biomarker may be useful in predicting severe exacerbations of BA. PMID:27776186

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.

Objective: To measure the serum leptin concentration in simple obese children together with other four kinds of related hormones. Methods: Serum Leptin, Ins, T 3 , T 4 and GH levels were measured by radioimmunoassay in thirty-eight obese children and thirty healthy controls. Results: The levels of serum leptin, Ins and T 3 in obese group were dramatically higher than those in control group (all P 4 concentration between simple obese children and control group (P > 0.05), Serum GH levels was significantly decreased in simple obese children (P < 0.01). There was a positive correlation between serum leptin levels and lns levels (r = 0.46, P < 0.01). Conclusion: In simple obese children there were leptin resistance and endocrine metabolic disturbances, the later might be correlated with the increasing of serum leptin levels; It is suggested that Leptin resistance might play a key role in the development of obesity

Full Text Available Background and objective Serum levels of tumor markers are associated with tumor metabolism or apoptosis, changes of which after chemotherapy may reflect tumor response to treatment. The aim of this study was to assess the predictive role of changes in serum levels of carcinoembryonic antigen (CEA and cytokeratin 19 fragment (CYFRA 21-1 during chemotherapy in patients with advanced non-small cell lung cancer. Methods Changes in serum levels of CEA and CYFRA 21-1 were investigated retrospectively after one cycle of chemotherapy in 42 patients with advanced NSCLC. Correlations between the changes and radiological objective response were analyzed. Results After two cycles of chemotherapy, radiological objective response rate was 28.6%. At baseline, gender, age, clinical stage, serum levels of CEA and CYFRA 21-1 were not different between patients with objective response (OR and no response (NR. After one cycle of chemotherapy, compared to baseline level, declines in serum levels of CEA and CYFRA 21-1 were observed in patients with OR, but have no statistical significance. In contrast, reduction of CEA and CYFRA 21-1 over baseline after one cycle of chemotherapy showed statistically significant difference between OR and NR. When reduction percentages of CEA and CYFRA 21-1 were used to predict objective response of chemotherapy, the area under the ROC curve (AUC was 0.875 for CEA and 0.919 for CYFRA 21-1. According to the ROC curve, a 22% reduction of CEA yielded a sensitivity of 58.3% and a specificity of 97%, 51% reduction of CYFRA 21-1 with a sensitivity of 83.3% and a specificity of 93.3%. When above reduction percentages were used as cutoffs for prediction of radiological objective response, combination of the CEA and CYFRA 21-1 yielded a sensitivity of 91.7% and a specificity of 86.7%. Conclusion Reduction percentages of CEA and CYFRA 21-1 during chemotherapy could be used to evaluate chemotherapy efficacy in patients with advanced NSCLC. The

pathogenesis of SSc. Heart fibrosis is one of the most important prognostic factors in SSc patients. So, the aim of our study was to examine cardiovascular dysfunction in SSc patients and its correlation with serum levels of vascular endothelial growth factor (VEGF, endostatin, and tissue inhibitor of metalloproteinase 2 (TIMP2. The study group comprised 34 patients (19 with limited scleroderma (lSSc and 15 with diffuse scleroderma (dSSc. The control group consisted of 20 healthy persons, age and sex matched. Internal organ involvement was assessed on the basis of specialist procedures. Serum VEGF, endostatin, and TIMP2 levels were evaluated by ELISA. We found cardiovascular changes in 15 patients with SSc (8 with lSSc and 7 with dSSc. The observed symptoms were of different characters and also coexisted with each other. Higher endostatin serum levels in all systemic sclerosis patients in comparison to the control group were demonstrated (P<.05. Also higher serum levels of endostatin and TIMP2 were observed in patients with cardiovascular changes in comparison to the patients without such changes (P<.05. The obtained results support the notion that angiogenesis and fibrosis disturbances may play an important role in SSc. Evaluation of endostatin and TIMP2 serum levels seems to be one of the noninvasive, helpful examinations of heart involvement in the course of systemic sclerosis.

Objective: To explore the dynamic of high-sensitivity C-reactive protein (hs-CRP) and its correlation with insulin resistance (IR) during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and thirty-one cases of normal glucose tolerance (NGT) pregnant women were enrolled in the study, fasting insulin (FINS) were determined by radioimmunoassay, the fasting blood glucose (FBG) was measured by using glucose oxidase, immunoturbidimetry performed to evaluate serum hs-CRP levels. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29- 32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model assessment insulin resistance index (HOMA-IR). Results: (1)Serum hs-CRP levels in NGT and GDM had few change with gestational age, but both significantly decreased at postpartum. (2)Serum hs-CRP levels in GDM significantly increased than NGT in the same stage (t was 7.31, 7.78, 6.33, respectively, P<0.01 ). (3) HOMA-IR in GDM significantly increased than NGT in the same gestational stage (t was 31.18, 31.10, 28.39, respectively, P<0.01). (4)Pearson correlation analysis showed that FBG, FINS and hs-CRP had significant association with HOMA-IR (regression coefficient of 0.478, 0.902, 0.293, respectively, P<0.01). Multiple regression analysis identified FINS, FBG and hs-CRP as the factors significantly affecting HOMA-IR (regression coefficient of 0.441, 0.876, 0.261, respectively, P<0.01). Conclusion: Serum hs-CRP levels in GDM had few change with gestational age, but all significantly increased than NGT in the same stage, and which were the most significant factors affecting HOMA-IR.

Osteopontin a matricellular protein has pro-fibrotic effects and binds integrin such as αvβ1 and αvβ3. Vitronectin is one of the integrin αvβ3 ligands and is a multifunctional glycoprotein. The aim of the present study was to evaluate serum osteopontin and vitronectin levels in a cohort of patients with systemic sclerosis (SSc). Eighty-six patients with SSc, 46 patients with systemic lupus erythematosus (SLE), and 38 healthy controls (HC) were enrolled in the study. Serum osteopontin, vitronectin, IL-6, and TGF-β levels were analyzed. Serum osteopontin levels were higher in the SSc and SLE groups compared to the HC group (p < 0.01 and p < 0.001, respectively). However, it was not correlated with disease activity and severity scores in the SSc group. On the other hand, serum vitronectin levels were lower in the SSc group than in the SLE and HC groups (p < 0.001 for both). These results may suggest that osteopontin levels may be increased due to the inflammatory process and osteopontin has not a specific role on fibrosis in SSc. On the other hand, serum vitronectin levels decrease in SSc in contrast to SLE. It may be concluded that the one cause of decreased serum vitronectin levels in SSc may be its accumulation in fibrotic area.

Full Text Available Background: Serum estradiol level is a controversial prognostic factor in the outcome of labial adhesion. The aim of this study was to evaluate serum estradiol levels and topical estrogen response in patients with labial adhesion.Methods: A prospective interventional study was conducted among girls with labial adhesion that referred to Pediatrics clinic in Taleghani University Hospital, Gorgan city, Iran in 2011. One hundred patients entered the study. The diagnosis was conducted by clinical examination of vestibule area. Inclusion criteria were, three months to eight years old prepuberty girls, no ambiguous genitalia, lack of vulvovaginitis symptoms, labial adhesion more than twenty five percent, no history of previous topical estrogen treatment since two weeks ago and previous incomplete treatment. The patients who did not use proper amount and duration of drug and also with adverse drug reactions during treatment period were excluded from the study. Results: The maximum frequency of labial adhesion was in the group of less than one year old. The minimum frequency of labial adhesion was in the 7-8 years old group. Eighty six patients had complete or partial remission. No evidence of an improvement was observed in fourteen children. Severity of adhesions did not worsen in our patients. Serum estradiol levels were lower in patients who had a positive response to treatment. There were significant differences in serum estradiol levels between full or relative improvement with no improvement groups (P=0.044.Conclusion: Findings of this study showed that the labial adhesion patients with low serum estradiol level had better treatment response after using topical estrogen.

Clinical data have suggested that obesity protects against osteoporosis. Leptin, mainly secreted by white adipose tissue, might be involved by mediating an effect on bone metabolism. This study was conducted to investigate a possible relationship of leptin and bone turn-over in postmenopausal women with osteoporosis. We measured bone mineral density (BMD), serum leptin levels and markers of bone metabolism, including osteocalcin and cross-laps in 44 patients with osteoporosis. The main group consisted of 32 postmenopausal women. Mean serum leptin was 13.1 microg/L and showed no statistically significant difference to the levels measured in a collective of normal persons adjusted for age and BMI. When related to serum cross-laps as markers of bone resorption, a positive correlation (posteoporosis.

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

Full Text Available 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.

Current evidence suggests heredity and metabolic syndrome contributes to gout progression. Specifically, the WDR1 and CLNK genes may play a role in gout progression in European ancestry populations. However, no studies have focused on Chinese populations, especially Tibetan individuals. This study aims to determine whether variations in these two genes correlate with gout-related indices in Chinese-Tibetan gout patients. Eleven single-nucleotide polymorphisms in the WDR1 and CLNK genes were detected in 319 Chinese-Tibetan gout patients and 318 controls. We used one-way analysis of variance to evaluate the polymorphisms' effects on gout based on mean serum levels of metabolism indicators, such as albumin, glucose (GLU), triglycerides, cholesterol, high-density lipoproteins (HDL-C), creatinine, and uric acid, from fasting venous blood samples. All p values were Bonferroni corrected. Polymorphisms of the WDR1 and CLNK genes affected multiple risk factors for gout development. Significant differences in serum GLU levels were detected between different genotypic groups with WDRI polymorphisms rs4604059 (p = 0.005) and rs12498927 (p = 0.005). In addition, significant differences in serum HDL-C levels were detected between different genotypic groups with the CLNK polymorphism rs2041215 (p = 0.001). Polymorphisms of CLNK also affected levels of albumin, triglycerides, and creatinine. This study is the first to investigate and identify positive correlations between WDR1 and CLNK gene polymorphisms in Chinese-Tibetan populations. Our findings provide significant evidence for the effect of genetic polymorphisms on gout-related factors in Chinese-Tibetan populations.

To compare serum zinc level between Thalassemia Major (TM) patients and normal population at Shafa Hospital in South West of Iran. A total of 25 male and 36 female of TM patients were enrolled in this study. Out of 61 patients thirty were treated by deferroxamine (DFO) and 31 were on the combination of DFO and deferiprone (DEF) protocol therapy. Sixty normal subjects of the matching age and gender were recruited as controls. From each patient and control group 2 ml of blood was taken in fasting condition. Cell blood count and serum zinc were carried out for both thalassemia patients and normal subjects. The mean age of patients and control group was 15+- 5 years. Mean serum zinc level was 68.97+- 21.12 mu g/dl, 78.10-28.50 mu g/dl, and 80.16+- 26.54 mu g/dl in the TM with DFO, TM with DFO + DEF combination protocol and control group respectively. There was no significant correlation between patients and control group. However 50 percent of TM with DFO, 38.7 percent of TM with DFO + DEF and 32.8 percent of control group had hypozincemia. Nearly 40 to 50 percent of TM patients and one third of normal subjects are suffering from hypozincemia. This study shows that low level of serum zinc is a health problem in both thalassemia patients and normal population in South West of Iran. (author)

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)

The aim of this study was to investigate the correlations between serum cartilage oligomeric matrix protein (COMP), interleukin-16 (IL-16) and different grades of knee osteoarthritis (KOA) in Malaysian subjects. Ninety subjects were recruited comprising 30 with Kellgren-Lawrence (K-L) grade 2 KOA, 27 with K-L grade 3 KOA, 7 with grade 4 KOA, and 30 healthy controls. All subjects completed the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. Serum COMP and IL-16 levels were measured using ELISA and their values log transformed to ensure a normal distribution. There was no significant differences in levels of log serum COMP and IL-16 between healthy controls and KOA patients. There were no significant differences in the log serum COMP and IL-16 levels within the different K-L grades in the KOA patients. In KOA patients, log serum IL-16 levels significantly correlated with the WOMAC score (p = 0.001) and its subscales, pain (p = 0.005), stiffness (p = 0.019) and physical function (p<0.0001). Serum IL-16 levels were significantly higher in Malaysian Indians compared to Malays and Chinese (p = 0.024). In this multi-ethnic Malaysian population, there was no difference in serum COMP and IL-16 levels between healthy controls and patients with KOA, nor was there any difference in serum COMP or IL-16 levels across the various K-L grades of KOA. However, there were significant inter-racial differences in serum IL-16 levels.

Full Text Available Background. Serum ghrelin levels may be related to metabolic and clinical changes in patients with psoriasis. Objective. This study was performed to determine the possible effects of serum ghrelin in patients with psoriasis. Methods. The study population consisted of 25 patients with plaque psoriasis. The patients were questioned with regard to age, gender, age of onset, duration of disease, height, weight, and body mass index (BMI. In addition, fasting blood sugar, triglyceride, cholesterol levels, insulin, and ghrelin levels were measured. Results. 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 Background and Aim: Recently, more attention was paid to the direct protective effect of aldosterone against hearing impairment in elderly patients. The aim of this study was determination of possible correlation between serum aldosterone level and hearing condition of elderly patients that referred to the Otolaryngology services of Hamadan in 2005-2006.Methods: In this case control study 54 (27 males,27 females persons above 60 years old were evaluated. They contained twenty eight cases with normal hearing and 26 cases with presbycusis. Persons with any abnormal biochemical finding or history of conditions that predispose them to the sensorineural hearing loss (SNHL were excluded. In both groups serum level of sodium, potassium and aldosterone were measured and hearing condition evaluated by puretone, speech and immitance audiometry.Results: Statistical relationship between serum aldostrone level and hearing condition, sex, configuration of audiogram and speech discrimination score (SDS were not significant. In addition, no significant relationship between sodium and potassium levels with hearing condition was found (p>0.05.Conclusion: This study could not confirm protective effect of aldostrone against presbycusis. This discrepancy may originate from epidemiologic differences, laboratory errors or small sample size.

To compare the serum AMH levels between women with and without insulin resistance (IR) in polycystic ovary syndrome (PCOS). 293 women with PCOS according to the Rotterdam criteria were enrolled into our study. Insulin resistance was diagnosed according to the Homeostatic model assessment insulin resistant (HOMA-IR) formula and the cut-off point was set to more than 2.5. Women were grouped according to the presence of insulin resistance (IR) (HOMA-IR ≥ 2.5). Serum AMH and other hormones were compared between the IR (+) and IR (-) groups. Additionally, AMH percentiles were (75) constructed; HOMA-IR and BMI values in women with/without IR were compared in different percentiles. Further, HOMA-IR, BMI and AMH values were measured across different PCOS phenotypes. The prevalence of IR was 45%. The prevalence of IR was 57% in women with BMI ≥ 25. Serum AMH levels were not significantly different among women with and without IR. Also, HOMA-IR values were not significant among different AMH percentiles. However, in each AMH percentile BMI were found to be higher in women with IR than in women without IR. The median HOMA-IR values were the highest in women with BMI ≥ 25 in both IR (+) and IR (-) groups. No significant difference was found among PCOS phenotypes in terms of HOMA-IR and BMI. Positive correlations were found between BMI, free testosterone and HOMA-IR. However, no correlation was found between AMH and HOMA-IR. The serum AMH levels between women with IR and without IR in PCOS were not significantly different. Also, we did not reveal a correlation between serum AMH levels and IR in women with PCOS. IR was not correlated with different PCOS phenotypes either. We found a positive correlation between BMI and IR. IR should be investigated in women with PCOS having a BMI ≥ 25, independent of their phenotype or AMH levels. Copyright © 2018 Elsevier B.V. All rights reserved.

To determine the predictive value of increased prolidase activity that reflects increased collagen turnover in patients with hepatocellular carcinoma (HCC). Sixty-eight patients with HCC (mean age of 69.1 ± 10.1), 31 cirrhosis patients (mean age of 59.3 ± 6.3) and 33 healthy volunteers (mean age of 51.4 ± 12.6) were enrolled in this study. Univariate and multivariate analysis were used to evaluate the association of serum α-fetoprotein (AFP) values with HCC clinicopathological features, such as tumor size, number and presence of vascular and macrovascular invasion. The patients with HCC were divided into groups according to tumor size, number and presence of vascular invasion (diameters; ≤ 3 cm, 3-5 cm and ≥ 5 cm, number; 1, 2 and ≥ 3, macrovascular invasion; yes/no). Barcelona-clinic liver cancer (BCLC) criteria were used to stage HCC patients. Serum samples for measurement of prolidase and alpha-fetoprotein levels were kept at -80 °C until use. Prolidase levels were measured spectrophotometrically and AFP concentrations were determined by a chemiluminescence immunometric commercial diagnostic assay. In patients with HCC, prolidase and AFP values were evaluated according to tumor size, number, presence of macrovascular invasion and BCLC staging classification. Prolidase values were significantly higher in patients with HCC compared with controls (P < 0.001). Prolidase levels were significantly associated with tumor size and number (P < 0.001, P = 0.002, respectively). Prolidase levels also differed in patients in terms of BCLC staging classification (P < 0.001). Furthermore the prolidase levels in HCC patients showed a significant difference compared with patients with cirrhosis (P < 0.001). In HCC patients grouped according to tumor size, number and BCLC staging classification, AFP values differed separately (P = 0.032, P = 0.038, P = 0.015, respectively). In patients with HCC, there was a significant correlation (r = 0.616; P < 0.001) between

Objectives: To assess the correlation of relative hepatic enhancement (RHE), relative renal enhancement (RRE) and liver to kidneys enhancement ratio (LKR) with serum hepatic enzyme levels and eGFR in Gd-EOB-DTPA enhanced MRI of the liver and to assess threshold levels for predicting enhancement of the liver parenchyma. Methods: Data of 75 patients who underwent Gd-EOB-DTPA enhanced MRI of the liver were collected. Images were obtained before contrast injection, during the early arterial phase, late arterial phase, venous phase, delayed phase, and hepatobiliary phase which was 20 min after Gd-EOB-DTPA administration. Signal intensity of the liver and the kidneys in all phases was defined using region-of-interest measurements for relative enhancement calculation. Serum hepatic enzyme levels and eGFR were available in all patients. Spearman correlation test was used to test the correlation of RHE, RRE and LKR with serum hepatic enzyme levels and eGFR. Results: In the hepatobiliary phase all serum hepatic enzymes were significantly correlated with RHE; total bilirubin (TBIL) and cholin esterase (CHE) showed strongest correlations. TBIL and CHE were significantly correlated with RRE in the arterial phases. TBIL and CHE were significantly correlated with LKR in the arterial phase and hepatobiliary phase. eGFR showed no correlation. Conclusions: In Gd-EOB-DTPA enhanced MRI, TBIL and CHE levels may predict RHE, RRE and LKR.

The purpose of this study is to see the effect of Dexketoprofen on TNF-α, IL-1, and IL-6 serum levels in Chronic Tension-Type Headache (CTTH) patients and its correlation with pain severity. The study subjects were recruited consecutively from the study population. Venous blood was taken at baseline to measure serum levels of TNF-α, IL-1, and IL-6 and after ten consecutive days of Dexketoprofen 25 mg once daily. Twenty three subjects participated in this study, 3 male (13.0%) and 20 female (87%). A significant difference between NRS score at baseline and after treatment (4.86 ± 1.82 vs. 1.96 ± 1.40, p = 0.001) was found. No significant difference found between baseline and after treatment TNF-α (1.48 ± 0.65 pg/dl vs. 1.48 ± 0.63 pg/dl, p = 0.963), IL-1 (0.16 ± 0.80 pg/dl vs. 0.26 ± 0.31 pg/dl, p = 0.168) nor IL-6 serum levels (1.06 ± 0.83 pg/dl vs. 1.04 ± 0.81 pg/dl, p = 0.915). A weak negative (R = -0.266) non significant correlation (p = 0.219) was found between NRS score and TNF-α. A positive weak negative (R = 0.221) non significant correlation (p = 0.311) between NRS score and IL-1. NRS score and IL-6 had a negative very weak (R = -0.019) non significant negative correlation (p = 0.931). Dexketoprofen decreased pain intensity significantly (p = 0.001), but had no effect on TNF-α IL-1 nor IL-6 serum levels. NRS score had a weak and non significant negative correlation with TNF-α, a weak and non significant positive correlation with IL-1, and a very weak and non significant negative correlation with IL-6 serum levels.

Objective. Recent data suggest that fetal antigen (FA1) is linked to disorders of body weight. Thus, we measured FA1 serum levels in two extreme nutritional states of morbid obesity (MO) and anorexia nervosa (AN) and monitored its response to weight changes. Design. FA1 and insulin serum concentrations were assessed in a cross-sectional study design at defined time points after gastric restrictive surgery for 25 MO patients and 15 women with AN. Results. Absolute FA1 serum levels were within the assay normal range and were not different between the groups at baseline. However, the ratio of FA1/BMI was significantly higher in AN. FA1 was inversely correlated with BMI before and after weight change in AN, but not in MO patients. In addition, MO patients displayed a significant concomitant decrease of FA1 and insulin with the first 25% of EWL, while in AN patients a significant increase of FA1 was observed in association with weight gain. Conclusion. FA1 is a sensitive indicator of metabolic adaptation during weight change. While FA1 serum levels in humans generally do not correlate with BMI, our results suggest that changes in FA1 serum levels reflect changes in adipose tissue turnover. PMID:22844611

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

Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value obese group of BMI. There was no significant difference of glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive

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.

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

To determine whether serum prostate specific antigen (PSA) level are increased in polycystic ovary syndrome (PCOS), 40 patients with PCOS, and 50 healthy control subjects were enrolled in the study.The subjects were compared by means of serum PSA T SHBG DHEA-S levels. The correlations between PSA and T SHBG DHEA-S were evaluated.Serum PSA levels were found to be significantly higher in PCOS (PSA: 15.64±3.36 pg/mL, in PCOS; PSA: 3.56±0.44pg/mL, in control; P<0.01). Positive correlations between PSA and T (r=0.467, P<0.01) and between PSA and DHEA-S (r=, 0.205 P<0.05) were found. A negative correlation between PSA and SHBG was apparent (r=-0.260, P<0.05). Females with PCOS tended to have higher PSA than females without PCOS (P<0.01). PSA appears to be a promising marker of androgen excess in females suffering from PCOS. (authors)

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.

Apolipoprotein E (ApoE), which has been shown to influence serum lipid parameters, can bind to multiple types of lipids and plays an important role in the metabolism and homeostasis of lipids and lipoproteins. A previous study showed that ApoE concentration significantly affects serum lipid levels independently of ApoE polymorphism. The serum lipid levels were also closely correlated with dietary habits, and Shandong cuisine is famous for its high salt and oil contents, which widely differ among the different areas in China. Therefore, studying the effect of ApoE polymorphism on ApoE concentration and serum lipid levels in Shandong province is very important.A total of 815 subjects including 285 men and 530 women were randomly selected and studied from Jinan, Shandong province. In order to evaluate the association of ApoE polymorphism and serum level on lipid profiles, the ApoE genotypes, as well as levels of fasting serum ApoE and other lipid parameters, were detected in all subjects.The frequency of the ApoE E3 allele was highest (83.1%), while those of E2 and E4 were 9.4% and 7.5%, respectively, which are similar to those in other Asian populations. ApoE2 allele carriers showed significantly increased ApoE levels but lower levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and Apolipoprotein B (ApoB).We found that ApoE level is influenced by ApoE polymorphism in a gene-dependent manner. The ApoE polymorphism showed different influences on serum lipid parameters with increasing age and body mass index (BMI) in our Shandong Han population.

Autism spectrum disorder (ASD) represents a very large set of neurodevelopmental issues with diverse clinical outcomes. Various hypotheses have been put forth for the etiology of autism spectrum disorder, including issues pertaining to oxidative stress. In this study, we conducted measurements of serum 8-Iso-Prostaglanding F2 α (8-iso-PGF2α, which is the results of non-enzimatically mediated polyunsaturated fatty acid oxidation) in a population of individuals with autism and a control group of age and sex matched controls. A quantitative assay of Paraoxonase 1 (PON1) was conducted. Data regarding comorbidities, structural MRI scans, medication, intelligence quotient (IQ) and Childhood Autism Rating Scale scores (CARS) were also included in our study. Our results show that patients diagnosed with autism have higher levels of 8-iso-PGF2α than their neurotypical counterparts. Levels of this particular metabolite, however, do not correlate with quantitative serum levels of Paraoxonase 1, which has been shown to be altered in individuals with autism. Neither 8-iso-PGF2α nor quantitative levels of PON1 provide any meaningful correlation with clinical or neuroimaging data in this study group. Future research should focus on providing data regarding PON 1 phenotype, in addition to standard quantitative measurements, in relation to 8-iso-PGF2α as well as other clinical and structural brain findings.

Polycystic ovarian syndrome (PCOS) is known to be one of the most prevalent endocrine disorders affecting reproductive age women. One of the endocrine disorder is hyperinsulinemia, which corresponds with the severity of PCOS. However, the pathogenesis of PCOS is not fully understood, but one theory of anti-mullerian hormone (AMH) has been proposed as one of the factor related to the degree of severity of PCOS. However, there are no clear correlation between levels of AMH with the incidence of insulin resistance in PCOS patients especially in Indonesia. This is a cross-sectional study involving reproductive age women aged 18-35 years. Subjects were recruited consecutively at Dr. Cipto Mangunkusumo General Hospital between 2011 until 2014. PCOS women diagnosed using 2003 Rotterdam criteria were categorized into four different PCOS phenotypes. Subsequently, serum level of AMH and HOMA-IR was measured and evaluated with correlation tests performed using SPSS 11.0 RESULTS: A total of 125 PCOS patients were included in a study conducted within a 3-year period. Phenotype 1 (anovulation, hyperandrogenism, and polycystic ovaries) shows the highest levels of AMH and HOMA-IR, which decreases in accordance to severity level (p HOMA-IR persisted even after adjusting for BMI in multivariate analysis. There was a positive correlation between serum AMH and HOMA IR levels. Serum AMH and HOMA IR levels were significantly different across the four PCOS phenotypes; with the highest values were present with phenotype 1.

Thioredoxin (Trx) is one of significant antioxidative molecules to diminish oxidative stress. Current evidence suggests that Trx is a potent antioxidant with cytoprotective functions. The aim of our study was to investigate specifically the association between serum Trx levels and acute ischemic stroke (AIS) patients. 198 AIS patients and 75 controls were enrolled to the study. Serum Trx levels were measured using an enzyme-linked immunosorbent assay (ELISA). Stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS) score on admission. Clinical endpoint was functional outcome measured by Barthel Index (BI) 3 months after admission. Multivariate binary logistic regression analyses were performed to identify predictors. We found that serum Trx levels were significantly increased in patients as compared to controls. Serum Trx was an independent biomarker to predict ischemic stroke (OR, 1.264; 95% CI, 1.04-1.537; P = 0.019). In addition, there was a negative correlation between NIHSS score at admission and serum Trx levels in cardioembolic stroke patients (r = -0.422; P = 0.013). Furthermore, higher serum Trx levels in AIS patients were associated with favorable functional outcome. Serum Trx was an independent predictor for the functional outcome (OR, 0.862; 95% CI, 0.75-0.991; P = 0.037). Serum Trx might be as a biomarker of cardioembolic stroke severity. Increased serum Trx levels could be a useful tool to predict good prognosis in patients with AIS.

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.

Nutritional status is an important factor in graft healing. Prealbumin (transthyretin) is a better nutritional marker than the widely used albumin serum level. Prealbumin serum levels were estimated in an endeavour to correlate them to graft healing and to serve as a predictor of graft healing in burn wounds. Fifty burned patients undergoing graft in the Suez Canal University Hospital Burn Unit were subjected to this cross-sectional study. Prealbumin levels were assessed on preoperative day and on the fourth postoperative day. Graft healing was considered complete when the take was 90% or more of the grafted area. The most significantly correlated factor to graft healing was serum prealbumin. Serum albumin levels were not in significant correlation with graft healing or prealbumin levels. In addition, serum prealbumin levels were significantly higher in the younger age group and significantly lower in patients with chronic diseases. Serum prealbumin level is a sensitive tool in predicting graft take in burned patients when all local conditions are favourable and optimised. Nevertheless, it seems less sensitive in the prediction of graft healing in small raw areas less than 5% of total body surface area (TBSA). (c) 2009 Elsevier Ltd and ISBI. All rights reserved.

D-dimer values are frequently increased in patients with atrial fibrillation (AF) compared with subjects in sinus rhythm. Hypokalemia plays a role in several cardiovascular diseases, but little is known about the association with AF. The aim of this study was to investigate correlations between D-dimer and serum potassium in acute-onset AF (AAF). To investigate the potential correlation between the values of serum potassium and D-dimer in patients with AAF, we retrospectively reviewed clinical and laboratory data of all emergency department visits for AAF in 2013. Among 271 consecutive AAF patients with D-dimer assessments, those with hypokalemia (n = 98) had significantly higher D-dimer values than normokalemic patients (139 versus 114 ng/mL, p = 0.004). The rate of patients with D-dimer values exceeding the diagnostic cut-off was higher in the group of patients with hypokalemia than in those with normal serum potassium (26.5% versus 16.2%; p = 0.029). An inverse and highly significant correlation was found between serum potassium and D-dimer (r = −0.21; p < 0.001), even after adjustments for age and sex (beta coefficient −94.8; p = 0.001). The relative risk for a positive D-dimer value attributed to hypokalemia was 1.64 (95% CI, 1.02 to 2.63; p = 0.040). The correlation remained statistically significant in patients free from antihypertensive drugs (r = −0.25; p = 0.018), but not in those taking angiotensin-receptor blockers, angiotensin-converting enzyme inhibitors, or diuretics. The inverse correlation between values of potassium and D-dimer in patients with AAF provides important and complementary information about the thromboembolic risk of these patients

Cystic fibrosis (CF) is characterized by low circulating levels of insulin-like growth factor-1 (IGF-1), a hormone produced by the liver that governs anabolism and influences immune cell function. Because treatment of CF pulmonary exacerbation (CFPE) often improves body weight and lung function, we questioned whether serum IGF-1 trends were emblematic of these responses. Initially, we compared serum levels between healthy adults with CF and controls of similar age. We then measured serum IGF-1 throughout the CFPE cycle. We also investigated correlations among IGF-1 and other serum biomarkers during CFPE. Anthopometric, spirometric, and demographic data were collected. Serum IGF-1 concentrations were measured by ELISA. CF subjects in their usual state of health had lower serum IGF-1 levels than controls. Serum IGF-1 concentrations fell significantly from baseline at the beginning of CFPE. Treatment with intravenous antibiotics was associated with significant improvement in serum IGF-1 levels, body mass index (BMI), and percent-predicted forced expiratory volume in 1 sec (FEV1 %). At early and late CFPE, serum IGF-1 was directly correlated with FEV1 %, serum iron, hemoglobin concentration, and transferrin saturation (TSAT) and indirectly correlated with alpha-1-antitrypsin. This study not only supports the paradigm that CF is characterized by IGF-1 deficiency but also that trends in lung function, nutritional status, and serum IGF-1 are related. Improvements in all three parameters after antibiotics for CFPE likely highlight the connection between lung function and nutritional status in CF. Close correlations among IGF-1 and iron-related hematologic parameters suggest that IGF-1 may participate in CF iron homeostasis, another process that is known to be influenced by CFPE. © 2013 Wiley Periodicals, Inc.

Galectin-1, a recently identified peptide, is primarily released from the adipose tissue. Although galectin-1 was shown to have an anti-inflammatory effect, its specific function is not clearly understood. We aimed to evaluate the relationship of serum galectin-1 levels with clinical and laboratory parameters in childhood obesity. A total of 45 obese children (mean age: 12.1±3.1years) and 35 normal-weight children (mean age: 11.8±2.2years) were enrolled. Clinical [body mass index (BMI), waist circumference (WC), percentage of body fat and blood pressure] and biochemical [glucose, insulin, lipids, galectin-1, high-sensitive C-reactive protein (hsCRP) and leptin levels] parameters were assessed. Serum galectin-1, hsCRP and leptin levels were significantly higher in obese children than those in normal-weight children (12.4 vs 10.2ng/mL, pobese children, galectin-1 levels correlated negatively with fasting glucose (r=-0.346, p=0.020) and positively with fat mass (r=0.326, p=0.026) and WC standard deviation score (SDS) (r=0.451, p=0.002). The multivariate regression analysis demonstrated that serum galectin-1 levels were significantly associated with fasting glucose and WC SDS. This study showed that obese children had significantly higher galectin-1 levels in proportion to fat mass in obese cases than those in healthy children, which may be interpreted as a compensatory increase in an attempt to improve glucose metabolism.

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 Background / objectives. Hyaluronic acid (HA is rarely described in dermatomyositis (DM. Thus, we determined any clinical association of serum levels of hyaluronic acid (HA in patients with dermatomyositis (DM. Materials and Methods. This cross-sectional single-center analysis 75 DM and 75 healthy individuals, during the period from January 2012 to July 2013. An anti-HA antibody assay was performed using specific ELISA/EIA kits, according to the manufacturer’s protocol. Results. The patients with DM and control subjects had comparable demographic distributions (p>0.05. The median time duration between disease diagnosis and initial symptoms was 6.0 [3.0-12.0] months, with a median DM disease duration of 4.0 [1.0-7.0] years. The median level of serum HA was significantly increased in patients with DM compared to the control group [329.0 (80.0-958.0 vs. 133.0 (30.0-262.0 ng/mL, respectively; p0.05. Serum HA also did not correlate with gender, ethnicity, auto-antibodies or drug use (p>0.05, but did correlate with cutaneous features, such as photosensitivity (p=0.001, “shawl” sign (p=0.018, “V-neck” sign (p=0.005 and cuticular hypertrophy (p=0.014. Conclusions. A high level of serum AH was observed in DM compared to healthy individuals. In DM, HA did not correlate to demographic, auto-antibodies and therapy parameters. However, HA correlated specifically with some cutaneous features, suggesting that this glycosaminoglycan could be involved in modulating cutaneous inflammation in this population. More studies are necessary to understand the correlation between AH and patients with DM.

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

The aim of this study was to evaluate KL-6 and CC16 levels and their correlation with neurodevelopmental outcome among very low birth weight pre-term infants at 12 months corrected age. This prospective cohort study was performed from 2011 to 2013 by enrolling pre-term neonates of gestational age ≤ 32 weeks and birth weight ≤ 1500 g. Serum KL-6 and CC16 levels were determined 7 days after birth and their correlation with neurodevelopment was evaluated using Gesell Mental Developmental Scales. Of the 86 eligible pre-term infants, 63 completed follow-up, of which 15 had bronchopulmonary dysplasia. At 12 months corrected age, 49 infants had favorable outcomes and 14 infants had poor neurodevelopmental outcome. KL-6 levels were higher and CC16 levels were lower in infants with poor neurodevelopmental outcome compared with those infants who had favourable neurodevelopmental outcome. Serum KL-6 levels less than 90.0 ng/ml and CC16 levels greater than 320.0 pg/ml at 7 days of life were found to be predictive of a favourable outcome at 12 months corrected age. These biological markers could predict neurodevelopmental outcome at 12 months corrected age in very low birth weight premature infants, and help the clinician plan early therapeutic interventions to minimize or avoid poor neurodevelopmental outcome.

Full Text Available Patients with polycystic ovary syndrome (PCOS usually are obese, insulin resistant and hyperinsulinemic. The known association between leptin, obesity andinsulin action suggests that leptin may have a role in PCOS but this has only been addressed peripherally. This study was designed to assess the relationship between serum leptin and the anthropometric, metabolic and endocrine variables of obese (body mass index, BMI ³30 kg/m² and non-obese (BMI <30 kg/m² PCOS patients. Twenty-eight PCOS patients and 24 control women subdivided into obese and non-obese groups were evaluated. Leptin, androgens, lipids, gonadotrophins and insulin-glucose response to the oral glucose tolerance test were measured by radioimmunoassay in all participants. The assays were done all in one time. The areas under the insulin curve (AUC-I and the glycemia curve were calculated to identify patients with insulin resistance. Mean leptin levels were not significantly higher in patients with PCOS compared to the control group (21.2 ± 10.2 vs 27.3 ± 12.4 ng/ml. Leptin levels were found to be significantly higher in the obese subgroups both in patients with PCOS (26.9 ± 9.3 vs 14.1 ± 7.0 ng/ml and in the control group (37.3 ± 15.5 vs 12.9 ± 5.8 ng/ml. The leptin of the PCOS group was correlated with BMI (r = 0.74; P < 0.0001 and estradiol (r = 0.48; P < 0.008 and tended to be correlated with the AUC-I (r = 0.36; P = 0.05. Of the parameters which showed a correlation with leptin in PCOS, only estradiol and probably insulinemia (AUC-I did not show a significant correlation with BMI, suggesting that the other parameters were correlated with leptin due to their correlation with BMI. Estradiol correlated with leptin in PCOS patients regardless of their weight.

We hypothesized that serum levels of C-X-C motif chemokine 13 (CXCL13), a B-cell chemokine, would delineate a subset of rheumatoid arthritis (RA) patients characterized by increased humoral immunity. Serum from patients with established RA (the Dartmouth RA Cohort) was analyzed for CXCL13, rheumatoid factor (RF) levels, anticitrullinated peptide/protein antibody (ACPA) and total immunoglobulin G (IgG); other parameters were obtained by chart review. A confirmatory analysis was performed using samples from the Sherbrooke Early Undifferentiated PolyArthritis (EUPA) Cohort. The Wilcoxon rank-sum test, a t-test and Spearman's correlation analysis were utilized to determine relationships between variables. In both the Dartmouth and Sherbrooke cohorts, CXCL13 levels were selectively increased in seropositive relative to seronegative RA patients (P = 0.0002 and P < 0.0001 for the respective cohorts), with a strong correlation to both immunoglobulin M (IgM) and IgA RF levels (P < 0.0001). There was a weaker relationship to ACPA titers (P = 0.03 and P = 0.006, respectively) and total IgG (P = 0.02 and P = 0.14, respectively). No relationship was seen with regard to age, sex, shared epitope status or inclusion high-sensitivity C-reactive protein (hsCRP) in either cohort or regarding the presence of baseline erosions in the Sherbrooke Cohort, whereas a modest relationship with Disease Activity Score in 28 joints CRP (DAS28-CRP) was seen in the Dartmouth cohort but not the Sherbrooke cohort. Using both established and early RA cohorts, marked elevations of serum CXCL13 levels resided nearly completely within the seropositive population. CXCL13 levels exhibited a strong relationship with RF, whereas the association with clinical parameters (age, sex, DAS28-CRP and erosions) or other serologic markers (ACPA and IgG) was either much weaker or absent. Elevated serum CXCL13 levels may identify a subset of seropositive RA patients whose disease is shaped by or responsive to RF

Full Text Available Hypoalbuminemia may cause interstitial edema and hemodilution, which we hypothesized may influence serum sodium levels. Our purpose was to compare serum sodium levels of hospitalized adults with or without hypoalbuminemia. All sodium and albumin serum levels of 142 adults hospitalized at general medical wards over a six-month period were searched at a University Hospital mainframe computer. Relevant laboratory data and clinical details were also registered. Hypoalbuminemia was defined by serum albumin concentration < 3.3 g/dl Fisher, Mann-Whitney, and Student's t tests were applied to compare groups with or without hypoalbuminemia. Ninety-nine patients, classified as hypoalbuminemic, had lower blood hemoglobin (10.68 ± 2.62 vs. 13.54 ± 2.41, and sodium (135.1 ± 6.44 vs. 139.9 ± 4.76mEq/l and albumin (2.74 ± 0.35 vs. 3.58 ± 0.28g/dl serum levels than non-hypoalbuminemic (n=43. Pearson's coefficient showed a significant direct correlation between albumin and sodium serum levels (r=0.40 and between serum albumin and blood hemoglobin concentration (r=0.46. Our results suggest that hypoalbuminemic adults have lower serum sodium levels than those without hypoalbuminemia, a phenomenon that may be at least partially attributed to body water retention associated with acute phase response syndrome.

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.

smoking is an important risk factor for placental abruption with strong dose-dependency. Pregnant smokers often underreport tobacco use which can be objectively assessed by measuring serum cotinine levels. We examined the accuracy between self-reported smoking habits and early pregnancy serum cotinine levels in women with or without placental abruption. retrospective case-control study. university Hospital. a total of 175 women with placental abruption and 370 control women. serum samples collected during the first trimester were analyzed for serum cotinine levels. Cotinine concentration over 15 ng/ml was considered as the cutoff indicating active smoking. Smoking habits of the women and their partners were recorded at the same visit. placental abruption. of the cases of women with placental abruption, 27.4% reported smoking compared with 14.3% of the controls (p smoked daily correlated well with the cotinine levels (r = 0.68, p smoking habits correlate well with serum cotinine levels in Finland. Therefore, self-reported smoking can be considered as a risk marker for placental abruption.

For measuring serum 3,3',5'-triiodothyronine (rT3) levels, radioimmunoassay (RIA) has traditionally been used owing to the lack of other reliable methods; however, it has recently become difficult to perform. Meanwhile, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has recently been attracting attention as a novel alternative method in clinical chemistry. To the best of our knowledge, there are no studies to date comparing results of the quantification of human serum rT3 between LC-MS/MS and RIA. We therefore examined the feasibility of LC-MS/MS as a novel alternative method for measuring serum rT3, thyroxine (T4), and 3,5,3'-triiodothyronine (T3) levels. Assay validation was performed by LC-MS/MS using quality control samples of rT3, T4, and T3 at 4 various concentrations which were prepared from reference compounds. Serum samples of 50 outpatients in our department were quantified both by LC-MS/MS and conventional immunoassay for rT3, T4, and T3. Correlation coefficients between the 2 measurement methods were statistically analyzed respectively. Matrix effects were not observed with our method. Intra-day and inter-day precisions were less than 10.8% and 9.6% for each analyte at each quality control level, respectively. Intra-day and inter-day accuracies were between 96.2% and 110%, and between 98.3% and 108.6%, respectively. The lower limit of quantification was 0.05 ng/mL. Strong correlations were observed between the 2 measurement methods (correlation coefficient, T4: 0.976, p < 0.001; T3: 0.912, p < 0.001; rT3: 0.928, p < 0.001). Our LC-MS/MS system requires no manual cleanup operation, and the process after application of a sample is fully automated; furthermore, it was found to be highly sensitive, and superior in both precision and accuracy. The correlation between the 2 methods over a wide range of concentrations was strong. LC-MS/MS is therefore expected to become a useful tool for clinical diagnosis and research.

Chemerin is a recently identified adipokine suggested to play a role in obesity and its metabolic complications. The relationship between visceral obesity and serum chemerin levels in type 2 diabetes (T2DM) is unknown and may differ from that of subjects without diabetes. Therefore, we evaluated whether serum chemerin was associated with visceral abdominal obesity in patients with T2DM. A total of 218 Korean patients with T2DM were enrolled and metabolic parameters, abdominal visceral and subcutaneous fat areas, and serum chemerin levels were measured. Serum chemerin level showed positive correlation with fasting insulin, HOMA-IR, serum triglyceride, serum creatinine, urine albumin/creatinine ratio, high-sensitivity C-reactive protein (hsCRP), fibrinogen, abdominal visceral fat area, visceral to subcutaneous fat area ratio, and negatively correlation with high density lipoprotein cholesterol and creatinine clearance (CCr) after adjusting for age, gender and body mass index. Multiple linear stepwise regression analysis showed that abdominal visceral fat area (β = 0.001, P abdominal visceral fat area, serum triglyceride, hsCRP and fibrinogen and lower level of CCr in patients with T2DM. Serum chemerin may be used as a biomarker of visceral adiposity and chemerin may play a role in inflammation, decreased renal function, and increased cardiovascular risk in T2DM.

Serum immunoglobulins (SI) were determined in 803 survivors and matched controls. Each subject's age, sex, health, exposure, and medical record were evaluated with respect to serum IgG, IgA, IgM levels. The IgG and IgA levels tended to be higher for this Hiroshima population than for Americans. Past exposure to ionizing radiation showed no significant correlation to SI levels. However, age and sex did influence the SI. IgM was significantly higher in females. With advancing age IgG and IgA increased in males, and IgM decreased in females. Elevated sedimentation rate and increased lymphocytes were accompanied by increased SI levels. Radiographic TB was detected in 45% of the population; IgG and IgA levels were somewhat elevated in these individuals. (DLC)

Transglutaminase (TG)2 is the autoantigen in celiac disease, but also TG3 antibodies have been detected in the serum of celiac disease patients. To investigate the correlations between serum TG3 antibodies and clinical and histological manifestations of celiac disease and to assess gluten-dependency of TG3 antibodies. Correlations between serum TG3 antibody levels measured from 119 adults and children with untreated coeliac disease and the demographic data, clinical symptoms, celiac antibodies, histological data and results of laboratory tests and bone mineral densities were tested. TG3 antibodies were reinvestigated in 97 celiac disease patients after 12 months on a gluten-free diet (GFD). TG3 antibody titers were shown to correlate with the age at celiac disease diagnosis. Further, negative correlation with TG3 antibodies and intestinal γδ+ cells at diagnosis and on GFD was detected. Correlations were not detected with the clinical manifestation of celiac disease, TG2 or endomysial autoantibodies, laboratory values, severity of mucosal villous atrophy, associated diseases or complications. TG3 antibody titers decreased on GFD in 56% of the TG3 antibody positive patients. Serum TG3 antibody positivity in celiac disease increases as the diagnostic age rises. TG3 antibodies did not show similar gluten-dependency as TG2 antibodies. Copyright © 2016 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

Background: D-dimer values are frequently increased in patients with atrial fibrillation (AF) compared to subjects in sinus rhythm. Hypokalemia plays a role in several cardiovascular diseases, but little is known about the association with AF. Objective: D-dimer values are frequently increased in patients with atrial fibrillation (AF) compared with subjects in sinus rhythm. Hypokalemia plays a role in several cardiovascular diseases, but little is known about the association with AF. The aim of this study was to investigate correlations between D-dimer and serum potassium in acute-onset AF (AAF). Methods: To investigate the potential correlation between the values of serum potassium and D-dimer in patients with AAF, we retrospectively reviewed clinical and laboratory data of all emergency department visits for AAF in 2013. Results: Among 271 consecutive AAF patients with D-dimer assessments, those with hypokalemia (n = 98) had significantly higher D-dimer values than normokalemic patients (139 versus 114 ng/mL, p = 0.004). The rate of patients with D-dimer values exceeding the diagnostic cut-off was higher in the group of patients with hypokalemia than in those with normal serum potassium (26.5% versus 16.2%; p = 0.029). An inverse and highly significant correlation was found between serum potassium and D-dimer (r = -0.21; p enzima conversora de angiotensina e diuréticos. Conclusões: A correlação inversa existente entre os níveis séricos de potássio e D-dímero em pacientes com FAA fornece informações importantes sobre o risco de tromboembolismo nestes pacientes.

Full Text Available ObjectiveTo evaluate serum creatine kinase (CK levels of amyotrophic lateral sclerosis (ALS patients and to explore the relationship between CK levels and the clinical characteristics and survival prognosis of ALS patients.MethodsWe analyzed the CK levels of 185 ALS patients who underwent long-term follow-up. The relationship between CK levels and clinical features including sex, age, disease duration, site of onset, body mass index (BMI, serum creatinine (Cr, and spontaneous electromyographic activity was analyzed by univariate analysis and multiple linear regression. Kaplan–Meier and Cox proportional hazards models were used to explore whether CK levels were independently correlated with survival prognosis of ALS.ResultsBaseline serum CK was raised in 43% of participants. The median CK level was 160 U/L (range: 20–2,574 U/L, and 99% of patients had a baseline serum CK level less than 1,000 U/L. CK levels were significantly higher in male patients than in female patients [204 (169 versus 117 (111 U/L, p < 0.001] and in patients with limb onset ALS than with bulbar onset ALS (p < 0.001. CK levels were also correlated with serum Cr (p = 0.011 and the spontaneous potential score of electromyography (EMG (p = 0.037 but not correlated with age (p = 0.883, disease duration (p = 0.116, or BMI (p = 0.481. Log CK was independently correlated with survival of ALS patients (HR = 0.457, 95% confidence interval 0.221–0.947, p = 0.035 after adjusting for age, sex, site of onset, serum Cr, and BMI.ConclusionSerum CK levels of ALS patients were correlated with sex, site of onsite, serum Cr, and spontaneous activity in EMG. Serum CK could be an independent prognostic factor for survival of ALS patients.

Objective: To determine the serum 25-hydroxycalciferol levels [25(OH)D] in adults with pre-diabetes and normoglycaemia to examine a possible association of vitamin D deficiency with pre-diabetes. Study Design: Case control study. Place and Duration of Study: Armed Forces Institute of Pathology, Rawalpindi, from November 2012 to July 2013. Methodology: A total of 272 adults including 136 pre-diabetics and 136 normoglycaemics of either gender aged 20 years and above were consecutively inducted. Patients with diabetes mellitus, pregnancy, rickets and osteomalacia, ischemic heart disease, chronic kidney disease and chronic liver disease were excluded. Fasting Plasma Glucose (FPG) was estimated with hexokinase method on Modular p800 Roche chemistry analyzer while serum 25(OH)D was measured on Diasorin Liaison immunoassay analyzer using the chemiluminescent technique. Mean 25(OH)D levels in pre-diabetic and normoglycaemic groups were compared using Mann-Whitney U test. Spearman's correlation coefficient 'rs' was determined between serum 25(OH)D and FPG. Odds ratio for vitamin D deficiency was also calculated. Results: Mean serum 25(OH)D level was low in pre-diabetics (23.2 nmol/L) as compared to normoglycaemics (29 nmol/L; p=0.001). Serum 25(OH)D level had inverse correlation with FPG (rs = -0.448, p=0.000). There was also significant association of vitamin D deficiency with pre-diabetes compared with normoglycaemia (OR: 2.21, p= 0.016; 95 percentage CI: 1.15-4.27). Conclusion: Vitamin D deficiency with pre-diabetes suggested that vitamin D may have an important role in pathogenesis of pre-diabetes. (author)

Objective: To investigate the possible relationship existing between serum sex hormones levels and development of essential hypertension. Methods: Serum sex hormones (LH, FSH, E 2 , P, T) levels were determined with RIA in 87 males and 81 post-menopausal women with essential hypertension as well as in 44 normotensive males and 40 normotensive post-menopausal women serving as controls. Results: The serum E 2 , progesterone and testosterone levels in the hypertensives were significantly higher than those in the respective controls (P 0.05). Sex hormones levels were not much different among hypertensives of various stages (I , II, III). The serum E 2 levels in male hypertensives and progesterone levels in female hypertensives were not correlated with the respective FSH and LH levels. Conclusion: The authors suggested that the changes of serum sex hormones levels might be a risk factor rather than a consequence of the development of essential hypertension. (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

Venous blood was collected after an overnight fast and 25-hydroxyvitamin D, glucose and insulin levels were measured. HOMA-IR was calculated. Bone mineral density was measured with a dual X-ray absorptiometer. There was no difference in serum 25-hydroxyvitamin D levels and HOMA-IR values between the two groups. A weak positive correlation between serum 25-hydroxyvitamin D levels and osteopenia was detected. Insulin resistance had a weak negative association with osteopenia. The correlations between osteopenia and serum 25-hydroxyvitamin D levels and HOMA-IR values were weak among early postmenopausal women.

Full Text Available Fetuin-A is a calcification inhibitor, negative acute phase response marker and cardiovascular mortality predictor in hemodialysis patients. Low levels of fetuin-A are associated with malnutrition, inflammation, decreased bone mass density, low-turnover bone and use of high calcium concentration dialysate. Hemodialysis procedure (HD has been shown to decrease fetuin-A levels by 20%, probably due to HD-induced inflammation or acute changes in calcium metabolism. The aim of our study was to investigate effects of HD on serum fetuin-A levels. Forty clinically and hemodynamically stable hemodialysis patients (21 females, 68 (38-85 years underwent routine bicarbonate hemodialysis or hemodiafiltration with polysulfone dialyzer. On consecutive HD dialysis solution with different calcium concentration with/without citric acid was used to assess influence of calcium shifts and parathyroid activity on fetuin-A changes during HD. All other parameters of HD were kept constant. Serum fetuin-A, calcium, phosphorus, iPTH, CRP and other biochemical parameters were measured before and after each HD. Our data show that predialysis serum fetuin-A levels have positive correlation with iPTH levels (p<0.05 and tendency to decrease with higher CRP levels. There was no change in fetuin-A levels during HD: 206 (167.1; 231.9 ug/ml before and 208.9 (170.3; 246.3 ug/ml after HD; respectively. When corrected for haemoconcentration, decrease in fetuin-A was only 2.8% (p<0.05. There was also no difference between effect of hemodialysis and hemodia-filtration procedure. The use of different calcium dialysate concentrations had distinct effect on iPTH levels during and after HD, however, we observed no associated changes in fetuin-A levels. The use of dialysate solution with citric acid had no effect on fetuin-A levels. In conclusion, standard bicarbonate HD with polysulfone dialyser and ultrapure dialysate induces only minor changes in fetuin-A and no changes in hsCRP levels

We aimed to investigate the association between serum levels of ghrelin and brain-derived neurotrophic factor (BDNF) with MetS and its components in premenopausal women. 43 patients with MetS and 43 healthy controls participated in this study. Participants' body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP) were measured. Serum levels of total cholesterol (TC), triglyceride (TG), low and high density lipoprotein cholesterol (LDL-C and HDL-C), fasting blood sugar (FBS), insulin, BDNF and ghrelin determined. Homeostasis model assessment insulin resistance index (HOMA-IR) was also calculated. Participants in MetS group had higher waist-to-hip ratios, elevated SBP and DBP, and higher serum levels of TG, FBS and insulin when compared with the control group. Serum ghrelin and BDNF levels were significantly lower in participants with MetS than in the healthier control subjects. There was a strong, positive correlation between serum ghrelin and BDNF levels. Both proteins negatively correlated with TG, FBS, HOMA-IR and positively with HDL-C. Furthermore, serum BDNF levels negatively associated with insulin levels. The findings indicate that variations occur in the circulating level of ghrelin and BDNF proteins in MetS patients. A strong correlation between serum ghrelin and BDNF suggests that production, release or practice of these 2 proteins might be related mechanically.

This study aimed to investigate the effects of sleep deprivation on serum cortisol level and mental health and explore the correlations between them in servicemen. A total of 149 out of the 207 Chinese servicemen were randomly selected to go through 24hour sleep deprivation, leaving the rest (58) as the control group, before and after which their blood samples were drawn for cortisol measurement. Following the procedure, all the participants were administered the Military Personnel Mental Disorder Prediction Scale, taking the military norm as baseline. The results revealed that the post-deprivation serum cortisol level was positively correlated with the factor score of mania in the sleep deprivation group (rSp=0.415, pSleep deprivation could significantly increase serum cortisol level and may affect mental health in servicemen. The increase of serum cortisol level is significantly related to mania disorder during sleep deprivation. Copyright © 2015 Elsevier B.V. All rights reserved.

Zinc (Zn) is known to interact with lead (Pb) and cadmium (Cd) reversing their toxicity and reducing their concentrations. However, lactating women are at high risk of developing Zn deficiency, which may result in Pb and Cd intoxication or increased exposure of breast-fed infants to Pb and Cd from breast milk. The aim of this study was to determine Zn, Pb, and Cd concentrations and examine their relationship in serum and breast milk of lactating women in Ibadan, Nigeria. Ninety-two lactating women were recruited into this study. Anthropometric measurements were assessed by standard methods while serum and breast milk concentrations of Zn, Pb, and Cd were assessed by atomic absorption spectrophotometry. Data analyzed statistically by Student's t test, Pearson's correlation coefficient, and a multiple regression model were significant at p < 0.05. Zn deficiency was observed in 12 (17.1%) of lactating women. Breast milk levels of Zn, Pb, and Cd were significantly higher than their levels in serum, whereas the ratios Zn:Pb and Zn:Cd in milk were significantly less than serum ratios. Significant negative correlation was observed between milk Pb and serum Zn:Pb while milk Cd correlated positively with milk Zn. Significant positive correlations were observed between serum Zn and serum Zn:Pb, serum Zn and serum Zn:Cd, as well as serum Zn:Cd and serum Zn:Pb. Serum Cd and serum Zn were significantly negatively related. Significant negative correlations between serum Pb and serum Zn:Pb as well as milk Zn:Pb. Serum Cd and serum Zn:Pb as well as serum Zn:Cd correlated negatively. Milk Cd and Zn/Cd positively related with milk Pb while milk Zn was a negatively related with milk Pb in a multiple regression model ( R 2 = 0.333; p = 0.023). Breast milk may be contaminated by toxic metals. However, Zn supplementation in deficient mothers may protect maternal and infant health.

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

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

Objectives: To investigate the relationship between lipid levels and oxidative stress index in healthy young adults. Methods: The study was camed out at the Department of Emergency Service, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey, between January 2011 and July 2012. A total of 100 healthy adult volunteers were enrolled in the study. Venous blood samples (10 ml) were collected from all individuals, and serum lipid parameters, total antioxidant capacity and total oxidative levels were studied. SPSS 15 was used for statistical analysis. Results: Overall, there were 84 (84%) males and 16 (16%) females. The mean age of the male population was 30+-3 years, while that of the females was 31+-3 years. Overall age ranged from 25 to 35 years. A statistically significant correlation was found between the oxidative stress index and serum cholesterol (p<0.001; r=0.596), triglyceride (p<0.001; r=0.476) and low-density lipoprotein levels (p<0.001; r=0.318). However, no significant correlation was found between oxidative stress index and serum high-density lipoprotein levels (p=0.564; r=0.058). Conclusion: The results showed that even at an early age, there is a direct linear correlation between oxidative stress and serum lipid levels. (author)

Background/Aims Lipopolysaccharide (LPS) is a molecule formed by lipids and polysaccharides and is the major cell wall component of gram-negative bacteria. High LPS levels are known to block CD26 expression by activating Toll-like receptor 4. The aim of this study was to correlate the serum levels of LPS and CD26 in Crohn's disease (CD) patients with serum levels of C-reactive protein (CRP), interleukins, CD activity index, and tumor necrosis factor-α (TNF-α). Methods Serum samples were collected from 27 individuals (10 with active CD, 10 with inactive CD, and 7 controls) and the levels of LPS, CD26, TNF-α, interleukin-1β (IL-1β), IL-6, IL-17, and CRP were determined by enzyme-linked immunosorbent assay. The levels of LPS and CD26 were then tested for correlation with TNF-α, IL-1β, IL-6, IL-17, and CRP. Results Serum levels of LPS were significantly elevated in the active CD group (P=0.003). Levels of IL-1β (P=0.002), IL-6 (P=0.003), and IL-17 (P<0.001) were lower in the CD groups. Serum TNF-α levels were increased in the active CD group. The CRP levels were elevated in the CD groups when compared to controls (P<0.001). The CD26 levels were lower in the CD groups than in the control group (P<0.001). Among the variables analyzed, there was a correlation between LPS and CRP (r=−0.53, P=0.016) in the CD groups. Conclusions Individuals with CD exhibited higher serum levels of LPS varying from a 2- to 6-fold increase depending on disease activity, when compared with healthy controls. CD26 levels were lower in the CD groups. Both LPS and CD26 correlated with disease severity and serve as potential CD biomarkers. PMID:28670232

Endothelial dysfunction has been described as the final common pathophysiological pathway in the development of preeclampsia. Since it has been suggested that homocyst(e)ine damages endothelial cells, we measured serum homocyst(e)ine levels in women with preeclampsia and in healthy pregnant women in order to find a new prognostic parameter for women with preeclampsia. Forty-five women with preeclampsia and 45 healthy women with uncomplicated pregnancies, matched for age and parity, were entered into the study. Serum homocyst(e)ine levels were measured by gas chromatography-mass spectrometry analysis and correlated to clinical data. Logistic regression models were used to analyse the influence of serum homocyst(e)ine levels on the presence of preeclampsia versus healthy pregnant women and on the risk of premature termination of pregnancy due to preeclampsia. Median serum homocyst(e)ine levels in women with preeclampsia and healthy pregnant women were 14.2 (range 5.7-38.1) mumol/L and 15.1 (range 5.2-23.1) mumol/L, respectively (Mann-Whitney U-test, p = 0.8). In univariate logistic regression models, serum homocyst(e)ine levels had no significant influence on the odds of presenting with preeclampsia versus healthy pregnant women (univariate logistic regression model, p = 0.8) and on the odds of premature termination of pregnancy due to preeclampsia (univariate logistic regression model, p = 0.3). Serum homocyst(e)ine levels are not elevated in women with preeclampsia and are not associated with clinical outcome in women with preeclampsia.

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

Objective: To investigate the inter-relationship among serum leptin insulin resistance and blood lipids, and to explore the role of leptin in the pathogenesis of ischemic cerebrovascular diseases (ICVD). Methods: Levels of serum leptin, insulin and blood lipids were determined with RIA in 131 patients with different types of ICVD and 36 controls. Results: The levels of serum leptin in ICVD patients were significantly higher than those in the controls (P<0.01). Changes of blood lipids and insulin paralleled those of leptin (cxcept with HDL-C). The serum leptin were positively correlated to cholesterol, TG and insulin levels (r=0.45, P<0.05; r=0.31, P<0.05, r=0.55, P<0.01), but negatively correlated to HDL-C (r=-0.88, P<0.05). Conclusion: The high expression of leptin in ICVD patients is associated with high lipid and insulin levels. The close relationship among them indicates that high leptin levels play an important role in the pathogenesis of metabolic syndrome as well as atheromatous cerebrovascular diseases. (authors)

Materials and Methods: A total of 100 healthy PMW were selected, and a prospective observational study was conducted to correlate the BMD with serum 25(OHD levels. Their laboratory investigations along with serum 25(OHD levels were done. Their BMD was assessed with dual-energy X-ray absorptiometry at lumbar spine and neck of femur; T-scores were derived. Correlation analysis was done to investigate the relationship between serum 25(OHD levels and BMD. Results: The proportion of osteoporosis at the hip was 31.9% in deficient group, 16.1% in insufficient, and 18.2% in sufficient group and at lumbar spine, it was 27.7%, 16.1%, and 22.7%, respectively. Forty-seven percent of PMW had deficient (<20 ng/ml serum 25(OHD levels and 31% had insufficiency. T-score at hip in deficient group was −2.05 ± 0.25, and in an insufficient group, it was −1.79 ± 0.13; T-score at lumbar spine was −1.92 ± 0.12 and −1.79 ± 0.12, respectively, but both were not statistically significant. Osteoporosis was seen in 24%, osteopenia in 55% at hip level and 23% and 59% respectively at lumbar spine. There was no association between serum 25(OHD levels and BMD neither at hip nor at lumbar spine ( P = 0.51 and P = 0.79 respectively. Conclusion: In this study, among our cohort of patients there was no correlation between serum 25(OHD levels and BMD. However, Vitamin D deficiency coexists with low BMD. Vitamin D insufficiency is a common risk factor for osteoporosis associated with increased bone remodeling and low bone mass.

Full Text Available Objective. Progranulin (PGRN was recently introduced as a novel marker of chronic inflammatory response in obesity and type 2 diabetes capable of directly affecting the insulin signaling pathway. This study aimed to investigate the correlation between PGRN and type 2 diabetics with microvascular complications. Methods. PGRN serum levels and glucose metabolism related substance were measured in 84 type 2 diabetic patients with or without microangiopathies and 12 health persons. Further analyses of serum PGRN in different stages of diabetic microangiopathies were conducted. Results. Serum levels of PGRN were markedly higher in type 2 diabetic patients with microangiopathies. PGRN serum levels increased with the progress of diabetic microangiopathies with significantly highest values detectable in clinical diabetic nephropathy (CDN and proliferative diabetic retinopathy (PDR groups. Serum PGRN concentrations in all individuals positively and markedly correlated with systolic blood pressure (SBP, diastolic blood pressure (DBP, body mass index (BMI, triglyceride (TG, urinary albumin excretion rate (UAER, blood urea nitrogen (BUN, creatinine (CRE, white blood cell (WBC, disease duration, IL-6, and TNF-α, while correlating negatively and significantly with eGFR. Multiple linear regression analysis showed that only UAER and CRE were independently associated with serum PGRN. Conclusion. PGRN might be considered as a marker for diabetic microangiopathy and its severity.

An unknown fraction of the genome participates in the metabolism of sterols and vitamin D, two classes of lipids with diverse physiological and pathophysiological roles. Here, we used mass spectrometry to measure the abundance of >60 sterol and vitamin D derivatives in 3,230 serum samples from a well-phenotyped patient population. Twenty-nine of these lipids were detected in a majority of samples at levels that varied over thousands of fold in different individuals. Pairwise correlations between sterol and vitamin D levels revealed evidence for shared metabolic pathways, additional substrates for known enzymes, and transcriptional regulatory networks. Serum levels of multiple sterols and vitamin D metabolites varied significantly by sex, ethnicity, and age. A genome-wide association study identified 16 loci that were associated with levels of 19 sterols and 25-hydroxylated derivatives of vitamin D (P < 10(-7)). Resequencing, expression analysis, and biochemical experiments focused on one such locus (CYP39A1), revealed multiple loss-of-function alleles with additive effects on serum levels of the oxysterol, 24S-hydroxycholesterol, a substrate of the encoded enzyme. Body mass index, serum lipid levels, and hematocrit were strong phenotypic correlates of interindividual variation in multiple sterols and vitamin D metabolites. We conclude that correlating population-based analytical measurements with genotype and phenotype provides productive insight into human intermediary metabolism.

To investigate the relationship of serum prostate-specific antigen (PSA) levels with outcomes of prostate needle biopsy in men 50 or more years old. We measured serum PSA levels in 1472 healthy men 50 or more years old. Men who had serum PSA values 4.0ng/mL or higher underwent digital rectal examination. If there were either an elevated PSA level (≥4ng/mL) or abnormal digital rectal examination, a transrectal ultrasound-guided prostate biopsy was performed. The mean serum total PSA level was 13.73±11.44ng/mL, and the mean serum free PSA level was 4.99±0.97ng/mL. Of the 260 men who had serum total PSA levels of≥4ng/mL, 139 underwent biopsy. Of these 139 men, 45 (32.4%) had prostate cancer. Benign prostatic hyperplasia with or without prostatitis was diagnosed in 94 patients (67.6%). There was no significant correlation between age and histologic results of prostate needle biopsy (P-value=0.469). The serum free PSA showed no significant correlation with histologic results of prostate needle biopsy, whereas the serum total PSA level had a significant correlation in patients with adenocarcinoma compared with other diagnosis. The overall frequency of detection of prostate adenocarcinoma was 32.4%. This study revealed that no level of PSA was associated with a 100% positive predictive value and negative biopsy can occur virtually at any PSA level. There is a need to create awareness among the general population and health professionals for an early diagnosis of this common form of cancer. Copyright © 2016 Société Française du Cancer.

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.

SERUM AND PAROTID FLUIS UREA-LEVELS IN UNREALOADED HEALTHY YOUNG ADULTS

Science.gov (United States)

Forty-four healthy young adult male subjects were given oral doses of urea, and parotid fluid and serum urea levels were studied for 1 to 3 hours. A...highly significant correlation between urea in serum and in parotid fluid (r equals 0.982) was found. The indication was that, with flow rate...carefully controlled, parotid fluid could be used interchangeably with serum in urea determination, regardless of the magnitude of the blood concentration.

We aimed to identify a noninvasive marker for clinically significant fetal uropathies. To achieve this aim, we detected TGF (transforming growth factor)-β1 serum level which rises in neonatal hydronephrosis, in pregnant patients with fetal hydronephrosis. We evaluated 44 patients, all of whom were pregnant and had a gestational age between 20 and 30 weeks. Twenty-two patients had normal maternal renal ultrasound imaging and had a fetus with fetal hydronephrosis (Group A). The remaining twenty-two patients had normal maternal and fetal renal ultrasound imaging (Group B). The maternal serum levels of TGF-β1 were measured with a sandwich enzyme-linked immunosorbent assay (ELISA) using a commercially available kit. The median value for the study group was 55.90 pg/mL (9.67 ± 574.45) and for the control group was 59.49 pg/mL (12.49 ± 402.04). There was no statistical difference in serum TGF-β1 levels between the groups (p = 0.769 - Mann-Whitney U test). In the study group, the diameter of the right renal pelvis was 5.7 mm (5.1-8.9 mm), while the diameter of left renal pelvis was 5.75 mm (5.3-10.04 mm). In our study, the circulating TGF-β1 levels were not statistically different in the fetal hydronephrosis group when compared to the controls. According to our study, TGF-β1 is not useful in the detection and follow-up of fetal hydronephrosis. We therefore require further studies involving larger groups with moderate or severe fetal hydronephrosis to detect the usefulness of the serum levels of TGF-β1 in pregnant women with fetal hydronephrosis.

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 analyze the correlation between the changes of myocardial enzyme level in serum before and after radiotherapy and dose - volume histogram (DVH) parameters of the heart. Methods: A total of 102 patients with 68 cases of lung cancer and 34 cases of esophageal cancer were recruited. All patients received three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT), with the radiation beams passing through the heart. Aspartate aminotransferase (AST), creatine kinase (CK), creatine kinase isozyme (CK-MB), lactate dehydrogenase (LDH), α-hydroxybutyrate dehydrogenase (α-HBDH) were determined in the serum before and after radiotherapy. All the enzyme levels before and after radiotherapy were compared through paired t-test. Independent sample t-test was conducted between sub-groups. And the dose-volume histogram (DVH) parameters of the heart were calculated (the volume percentage of heart receiving dose equal to or exceeding x Gy (V x ). The correlation between myocardial enzyme level and DVH parameters was analyzed through Pearson method. Results: Serum AST, CK-MB, LDH, α-HBDH levels increased significantly after radiotherapy (19.42: 27.89, 14.72:19.57, 178.80 : 217.57, 140.32 : 176.25, t =-3.39 - -6.92, all P=0.000). In Group IMRT, significant correlations between the increase of myocardial enzyme concentration and DVH parameters of the heart are found, AST with V 20 , V 25 , V 30 of heart ( r=0.302 - 0.431, P =0.039 - 0.003), CK with V 30 of heart (r=0.345, P=0.013), and CK-MB, LDH, α-HBDH with V 25 , V 30 (r=0.465 -0.376, P=0.001-0.005). In Group CRT, there are significant correlations between changes of CK-MB, LDH level and V 30 of heart (r =0.330, 0.274, P=0.014, 0.033), α-HBDH and V 25 , V 30 , and V 35 of heart (r=0.270-0.331, P=0.046-0.014). When the irradiation dose was more than 50 Gy, significant correlations were found between the concentration changes of AST, LDH, α-HBDH and V 25 , V 30 of heart (r=0

Inadequate vitamin D status is highly prevalent in the Korean population, especially among young adults. Nonetheless, correlates of suboptimal vitamin D levels in young adults are not well defined. This study aimed to investigate potentially modifiable determinants of vitamin D levels in young adults in Korea. This cross-sectional study was based on health check-up data from 3,450 healthy male and female university students aged 18-29 yr in Seoul between April and May 2013. Serum 25-hydroxyvitamin D [25(OH)D] levels were determined using chemiluminescent immunoassay. Anthropometric data were measured, and lifestyle, dietary, and sociodemographic factors were obtained through self-administered questionnaires. General linear regression was used to assess correlates of serum 25(OH)D levels. The mean serum 25(OH)D level was 11.1 ng/mL, and the prevalence of 25(OH)D levels less than 10 ng/mL was 44.7% (39.5% in men, 50.2% in women). In a final multivariable model, significant positive correlates of serum 25(OH)D were older age, male sex, increased physical activity, sunlight exposure ≥ 30 min/day, eating breakfast regularly, consumption of dairy and fatty fish, and use of vitamin D-containing supplements. In contrast, significant inverse correlates were obesity (body mass index, BMI ≥ 25 kg/m(2)) or underweight (BMI instant noodles and sugar-sweetened beverages. In conclusion, many modifiable lifestyle and dietary factors were associated with low serum 25(OH)D levels in Korean young adults. Further studies on potential mechanisms of the correlates and optimal strategies to improve vitamin D status in this vulnerable subpopulation are warranted.

Objective: To investigate the changes of serum levels of insulin-like growth factor II (IGF II) and adrenomedullin (ADM) in patients with essential hypertension. Methods: Serum IGF II and ADM levels were measured in 62 cases of hypertension and 40 controls with RIA. Results: Serum IGF II and ADM levels were significantly bigger in hypertensive patients than those in the controls (t = 4.454, p < 0.01; t = 3.992, p < 0.01). The serum IGF II level was significantly positively correlated to the serum ADM levels (r = 0.379, p < 0.05) and both were significantly positively correlated to the mean arterial pressure (r = 0.346, r = 0.353, p < 0.05) but not with BMI. Serum ADM levels increased gradually as the disease progressed from stage I to stage III (p < 0.05) with levels in stage III markedly higher than those in stage I (p < 0.01). In EH patients with heart and/or brain and/or renal complications the serum ADM levels were significantly higher than those in EH patients without complications (t = 2.050, p < 0.05). Such differences did not exist in the case of IGF II. Conclusion: Serum IGF II and ADM levels were increased markedly in hypertensive patients. These two factors were mutually positively correlated and both were positively correlated to mean arterial pressure. ADM levels increased gradually as the disease progressing but IGF II levels remained stable

High serum albumin levels during ischemic stroke (IS) decrease the risk of a poor outcome. This study aimed to determine whether serum albumin levels within the first days after IS correlate with radiological and biochemical markers of brain tissue damage. Fifty-six IS patients were enrolled into the study. Neurological examinations were based on the National Institute of Health Stroke Scale. Serum albumin levels and S100BB were evaluated using commercially available ELISA kits. The albumin decrease index (ADI) was calculated as the difference between serum albumin levels measured on days 1 and 10 of IS. All parameters were estimated on the 1st, 3rd, 5th, and 10th days of IS, and the volume of ischemic focus was measured on the 10th day. Mean serum albumin levels were decreased during acute IS. There were correlations between the ADI and mean S100BB serum levels (r = 0.36, p albumin levels during the acute phase of IS corresponds to a worse neurological state as a result of a large ischemic focus with intense catabolic processes.

Objective: To investigate the variations of serum leptin levels in pregnant women of various trimesters and their neonates as well as the correlativity in-between. Methods: Serum leptin levels in 300 women at pregestation during the three trimesters and the umbilical blood leptin levels in their neonates were measured with RIA. Results: Serum leptin levels in pregnant women rose significantly only from midgestation with a peak at partum (p < 0.05 or p < 0.01 vs pregestation). The leptin levels in neonates were almost the same as those of women of pregestation. The maternal leptin levels were positively correlated to body weight, body weight-index, abdominal perimeter, height of fundus of uterus, diastolic and systolic pressure. The leptin levels in neonates were positively correlated to the birth weight, but not correlated to maternal leptin levels. Conclusion: Leptin in neonates comes from neonates themselves, and its concentrations are determined by the degree of accumulation of body adipose tissue. Measurement of blood leptin concentrations in pregnant women during pregnancy has little meaning for accessing the body weight of fetus, but it can show the degree of maternal weight-gaining and may have some value for clinical observation of the syndrome of pregnant hypertension

Purpose Ocular and systemic measurement and imaging of the macular carotenoids lutein and zeaxanthin have been employed extensively as potential biomarkers of AMD risk. In this study, we systematically compare dual wavelength retinal autofluorescence imaging (AFI) of macular pigment with skin resonance Raman spectroscopy (RRS) and serum carotenoid levels in a clinic-based population. Methods Eighty-eight patients were recruited from retina and general ophthalmology practices from a tertiary referral center and excluded only if they did not have all three modalities tested, had a diagnosis of macular telangiectasia (MacTel) or Stargardt disease, or had poor AFI image quality. Skin, macular, and serum carotenoid levels were measured by RRS, AFI, and HPLC, respectively. Results Skin RRS measurements and serum zeaxanthin concentrations correlated most strongly with AFI macular pigment volume under the curve (MPVUC) measurements up to 9° eccentricity relative to MPVUC or rotationally averaged macular pigment optical density (MPOD) measurements at smaller eccentricities. These measurements were reproducible and not significantly affected by cataracts. We also found that these techniques could readily identify subjects taking oral carotenoid-containing supplements. Conclusions Larger macular pigment volume AFI and skin RRS measurements are noninvasive, objective, and reliable methods to assess ocular and systemic carotenoid levels. They are an attractive alternative to psychophysical and optical methods that measure MPOD at a limited number of eccentricities. Consequently, skin RRS and MPVUC at 9° are both reasonable biomarkers of macular carotenoid status that could be readily adapted to research and clinical settings. PMID:28728169

To evaluate preoperative serum levels of Ca125 and Tag72-4 tumour markers and investigate if abnormal levels correlate to mortality and disease-free survival. Retrospective observational study of a cohort of 282 women (mean age 62.3, SD 10.5 years) with primary endometrial cancer included all consecutive cases treated in a tertiary Gynaecological oncology Center. Excluded cases with other cancer or previous cancer treatment, major abdominal pathology or inflammation, endometriosis. Preoperative serum Tag72 and Ca125 levels were determined and evaluated in relation to disease-free survival (DFS) and disease-specific overall survival (DOS). Raised Ca125 correlates to worse overall disease-specific survival (66.1 vs 87.8 months, p = 0.021) and Tag72 correlates to shorter disease-free survival (69.2 vs 67.3 months, p = 0.021) and higher recurrence rate (13.5 vs 6 %, p = 0.021). When both Ca125 and Tag72 are abnormal DFS and DOS are worse. 93.3 % (72.3 months) vs 82.4 %, (61.3 months) p = 0.018 and 96.3 % (74.8 months) vs 88.2 %, (65.9 months) p = 0.021, respectively. This study enhances the value of preoperative tumour markers and their prognostic value. Ca125 and Tag72 appear to be good predictors of poor prognosis in patients with endometrial cancer.

Full Text Available Background: Obesity is a well-known principal risk factor for metabolic disorders and cardiovascular diseases. Resistin is one of adipocyte-derived molecules, which plays important roles in inflammation as well as in endocrine and cardiovascular systems. Objectives: The present study aimed to determine the association between serum resistin level and presence/severity of Coronary Heart Disease (CHD. Patients and Methods: This cross-sectional study was conducted on 155 individuals referred for coronary angiography. Information about the patients’ age, gender, and cardiovascular risk factors was recorded. Their weight, height, and waist and hip circumferences were measured, as well. Each coronary angiogram was reported for two scoring methods (number of vessel diseases (usual method and Gensini scoring system by one cardiologist who was not aware of the participants’ serum resistin levels. Then, the relationship between serum resistin level and presence/severity of CHD was evaluated. Results: The results revealed no significant associations between the mean serum resistin level and the presence of CHD by both methods of evaluation of the coronary angiograms after adjustment for all conventional risk factors for CHD. In addition, no significant association was detected between serum resistin level and the severity of CHD based on the usual method of reporting the coronary angiograms (number of vessel diseases (P = 0.332. Yet, serum resistin level was positively correlated to body mass index and waist and hip circumferences and negatively related to height and fasting blood sugar level. Moreover, no linear correlation was found between serum resistin level and Gensini score (P = 0.35. Finally, hip circumference (P = 0.002 and height (P = 0.018 were determined as the predictors of serum resistin level. Conclusions: This cross-sectional study showed no significant associations between serum resistin level and presence/severity of CHD.

The efficacy of statin therapy may be lost or vary with reduction in compliance and intensity of statin therapy. To study and correlate the quantitative effect of compliance on lipid profile and 3-hydroxyl-3-methylglutaryl coenzyme A reductase (HMGCoA-R) levels in dyslipidemic patients. Compliance to different intensity of statin therapy assessed by pill count was correlated with serum levels of total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (TG), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and HMGCoA-R. Out of 200 patients, 160 received moderate intensity statin therapy whereas 40 were on high intensity statin therapy. The overall mean compliance of patients was 56.7%. The compliance of patients on moderate intensity statin therapy was higher (56.8%) than those on high intensity (56.4%) (p=0.92). There was significant inverse correlation (pstatin therapy was increased above 60%. It is appropriate to improve the compliance to existing statin therapy than switching over to higher intensity statin therapy. Estimation of HMGCoA-R levels may be explored as a surrogate marker to monitor and assess the compliance of patients to statin therapy. Copyright © 2016. Published by Elsevier B.V.

Radioimmunoassay of serum digoxin levels in digitalis intoxication

Arendt, G.

1981-01-01

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

The aim of this study was to (1) optimize a method for the measurement of parabens and phenols in adipose tissue, (2) evaluate the stability of chemical residues in adipose tissue samples, and (3) study correlations of these compounds in urine, serum, and adipose tissue. Samples were obtained from adults undergoing trauma surgery. Nine phenols and seven parabens were determined by isotope diluted TurboFlow-LC-MS/MS. The analytical method showed good accuracy and precision. Limits of detection (LOD) for parabens and phenols ranged from 0.05 to 1.83ng/g tissue. Good recovery rates were found, even when biological samples remained defrosted up to 24h. Benzophenone-3 (BP-3; range of values: 70% of adipose tissue samples, while bisphenol-A (BPA; 40% of adipose tissue samples. In general, levels were similar between adipose tissue and serum, while a correlation between adipose tissue and urine was only found for BP-3. In conclusion, adipose tissue samples in this study were found to contain environmental chemicals considered to be non-persistent, whose levels were weakly or not at all correlated with the urine burden. Therefore, adipose tissue may potentially provide additional information to that obtained from other biological matrices. Further investigations are warranted to explore whether adipose tissue might be a suitable matrix for assessment of the consequences for human health of mid/long-term exposure to these chemicals.

Prolactin (PRL) is known to aid effector B cells and augment autoimmunity, but the role of PRL in systemic lupus erythematosus (SLE) is not fully elucidated. The aim of this study was to determine the correlation between the serum levels of PRL and autoantibody production in SLE. Blood levels of PRL, anti-double-stranded DNA (ds-DNA) antibody, immunoglobulin M (IgM) and immunoglobulin G (IgG) were determined in samples from 30 adult patients with SLE and 25 healthy controls. The relationships between the serum level of PRL and SLE disease activity, as well as the titres of the ds-DNA antibody, IgM and IgG were determined. The serum level of PRL was higher in the SLE patients than in the healthy controls. PRL concentration increased during SLE flares-ups and decreased following disease remission. There was a positive correlation between the PRL concentration and serum levels of IgM, IgG and ds-DNA antibody titre. These data suggest that the serum level of PRL was closely related to the antibody production and disease activity of SLE patients. PRL concentration was dramatically reduced upon the remission of disease activity, indicating that PRL levels might be a promising predictor of SLE disease severity. © The Author(s) 2015.

Inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) may have a direct effect on glucose and lipid metabolism. On the other hand, it is known that IL-6 and TNF-alpha are important pro-inflammatory cytokines in the pathogenesis of atherosclerosis. The goal of present study was to test whether sleep apnea contributes to the previously reported increases of IL-6 and TNF-alpha independent of obesity. Forty-three obese (body mass index, BMI>27 kg/m2) men with newly diagnosed obstructive sleep apnea syndrome (OSAS) (apnea-hypopnea index, AHI> or =5) and age- and BMI-matched 22 obese nonapneic male controls (AHI<5) were enrolled in this study. To confirm the diagnosis, all patients underwent standard polysomnography in the sleep disorders center. Serum samples were taken at 08:00 h in the morning after overnight fasting. Serum IL-6 and TNF-alpha levels were found significantly higher in OSAS patients than in controls (p=0.002, p=0.03). Serum IL-6 and TNF-alpha levels were significantly correlated with AHI in OSAS patients (r=0.03, p=0.046 and r=0.36, p=0.016). There was no significant correlation between serum IL-6, TNF-alpha levels and AHI in controls. Serum IL-6 and TNF-alpha levels were not correlated with BMI both in OSAS patients and controls. In conclusion, circulating IL-6 and TNF-alpha levels in patients with OSAS, as independent of BMI are significantly higher than levels in controls and there is a positive relationship between previously mentioned cytokines' levels and the severity of OSAS. According to these results, the link between cardiovascular morbidity and OSAS may be explained by the coexistence of other cardiovascular risk factors such as circulating IL-6 and TNF-alpha levels.

To investigate the link between serum vaspin levels and physical activity and/or physical fitness in Japanese. A total of 156 subjects (81 men and 75 women) was enrolled in this cross-sectional study. Serum vaspin levels, physical activity by uniaxial accelerometers, peak oxygen uptake, and metabolic risk parameters were evaluated. We also assessed anthropometric and body composition parameters. Serum vaspin levels were over the level of 10 ng/mL in 15 subjects (9.6 %: Vaspin High group). In Vaspin Low group (men and 67 women), serum vaspin levels were 0.12 ± 0.18 ng/mL in men and 0.39 ± 0.70 ng/mL in women. Peak oxygen uptake was significantly and positively correlated with serum vaspin levels even after adjusting for age, physical activity evaluated by Σ[metabolic equivalents × h per week (METs[Symbol: see text]h/w)], BMI, and other confounding factors in men. In turn, physical activity was significantly and positively correlated with serum vaspin levels even after adjusting for confounding factors in women. Serum vaspin levels were closely associated with physical fitness in men and physical activity in women independent of body composition in this Japanese cohort.

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

The aim of this study is to evaluate serum 25-hydroxyvitamin D[25(OH)D] levels in children with tic disorders and to explore the relationship between serum 25(OH)D level and tic severity. Children (n = 179, 31 females, 148 males, mean age at diagnosis: 8.0 ± 2.7 years old, age ranged from 3 to 14.5 years old) who were diagnosed with a tic disorder were enrolled as case group, 189 healthy children were recruited as control group. Serum level of 25(OH)D of each child was measured by high performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS). Yale Global Tic Severity Scale (YGTSS) was used to assess tic severity. Mean serum level of 25(OH)D in the case group was significantly lower than that of the control group. The serum 25(OH)D level was significantly associated with tic severity after adjusting for age and body mass index (BMI). This study identified a high prevalence of vitamin D insufficiency or deficiency in children with tic disorders, and there was a negative correlation between the serum 25(OH)D level and tic severity. In the future, large sample size studies are urgently needed to further clarify this correlation. Copyright © 2018. Published by Elsevier B.V.

Full Text Available ABSTRACT BACKGROUND Bariatric surgery is the most effective treatment for severe obesity, but the surgery increases the risk of developing nutritional deficiencies, such as vitamin A deficiency. In human metabolism, vitamin A plays a role in vision. OBJECTIVE To evaluate serum vitamin A, visual function and ocular surface of patients undergoing bariatric surgery. METHODS A cross-sectional and analytical study was conduced with 28 patients undergoing bariatric surgery for at least 6 months. Ophthalmologic evaluation was done through color vision test, contrast sensitivity test, ocular surface tests and confocal microscopy, as well as vitamin A serum measurement. RESULTS Vertical sleeve gastrectomy was performed in seven (25.0% patients and Roux -en-Y gastric by-pass in 21 (75.0%. Mean serum vitamin A level was 1.7±0.5 µmoL/L. Most patients (60.7% had symptoms of dry eye. Five (17.9% patients had contrast sensitivity impairment and 18 (64.3% color vision changes. In the group of patients undergoing Roux -en-Y gastric by-pass , mean vitamin A levels were 1.8±0.6 µmoL/L, whereas they were 1.7±0.5 µmoL/L in patients submitted to the restrictive technique vertical sleeve gastrectomy . The analysis of the influence of serum levels of vitamin A in the visual function and ocular surface was performed by Pearson correlation test and there was no significant correlation between any of the variables and vitamin A. CONCLUSION There was no influence of the bariatric surgery technique used on serum vitamin A levels, on the visual function or on the ocular surface. Moreover, there was no correlation between serum levels of vitamin A and the visual function or the ocular surface changes.

The levels of several inflammatory cytokines are abnormal in many patients with the fibromyalgia syndrome (FMS) and may play a role in its pathogenesis. The inflammatory marker C-reactive protein (CRP) is associated with the disease activity in patients with inflammatory rheumatic diseases, but its role in FMS is unknown. We undertook this study to determine whether high-sensitivity CRP (hsCRP) is elevated in FMS and whether its levels relate to key biologic or clinical measures. One hundred and five patients with FMS (1990 ACR criteria) and 61 healthy normal controls (HNC) at a ratio of 2:1 were recruited. The serum concentrations of hsCRP, interleukin-8 (IL-8), and interleukin-6 (IL-6) were assessed using enzyme-linked immunosorbent assays. The hsCRP levels were marginally higher in FMS than in HNC (p = 0.06) and its abnormality rate (>1.5 SD above the HNC mean) was significantly higher in FMS (25 %) compared with HNC (6.8 %) (p = 0.03). Serum IL-8 levels, IL-6 levels, and erythrocyte sedimentation rate (ESR) in FMS did not differ from those in HNC. Body mass index (BMI), ESR, IL-8, and IL-6 levels correlated with hsCRP levels in FMS. No associations were found between hsCRP and age, gender, ethnicity, or other clinical measures. Serum CRP levels were higher in FMS and significantly correlated with BMI, ESR, IL-8, and IL-6 levels, suggesting that inflammation may contribute to the symptoms in some FMS patients, particularly those who are obese. Weight loss and therapies directed against inflammation may be useful in the management of FMS patients with elevated hsCRP.

Full Text Available Background: Polycystic ovary syndrome (PCOS is a common disorder. PCOS women are at a high risk for insulin resistance and metabolic syndrome (MS. Adiponectin is positively related to insulin sensitivity. It has a preventive role in atherogenesis and MS. The present work was conducted to study the correlation between serum adiponectin levels and clinical characteristics and biochemical parameters in PCOS patients. Materials and Methods: A prospective study in 49 newly diagnosed (as per Rotterdam criteria Indian PCOS women was conducted. PCOS women were clinically examined and investigated for biochemical parameters. Results : The mean serum adiponectin was 12 ± 9.4 μg/mL (range 0.47-45. Hypoadiponectinemia (serum adiponectin <4 μg/mL was present in 22% patients. Age and adiponectin correlated significantly and inversely (r = −0.42, P = 0.027. Overweight/obese patients had lower mean adiponectin levels than normal weight (11.62 ± 9.5 vs 13.58 ± 9.5, P = 0.56. It was significantly lower in patients with acanthosis nigricans (AN as compared with those without AN (8.4 ± 5.9 vs 15 ± 11, P = 0.038. Hirsute patients showed lower mean adiponectin levels than nonhirsute (10 ± 7.3 vs 13 ± 10, P = 0.57. A positive, insignificant correlation was observed between serum adiponectin and cholesterol, low-density lipoprotein, follicle stimulating hormone (FSH, thyroid stimulating hormone, levels. A negative insignificant correlation existed between serum adiponectin and luteinizing hormone (LH, LH: FSH ratio, prolactin, dehydroepiandrosterone, testosterone, triglyceride, high-density lipoprotein, fasting blood glucose, fasting insulin, and Homeostasis Model Assessment. Conclusion: Hypoadiponectinemia is present in one-fifth of women with PCOS. Adiponectin levels decrease as age advances. Low levels of adiponectin possibly contributes to the development of dermal manifestation (AN of insulin resistance.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children. (orig.)

Twenty-five known fertile male selected from general population (their spouse had given birth to a child within one year) and after semen analysis were taken as normospermic control group. Semen analyzed according to WHO criteria and serum and seminal plasma zinc was estimated by 5Br. PAPS colorimetric method. Serum testosterone, LH, and FSH were measured by ELISA, using kits supplied by Diagnostic System Laboratories (DSL), U.S.A. Results: The mean value for testosterone was significantly low in oligospermic, (8.04+0.76) and azoospermic subjects (7.14+0.27) as compared to normospermic (9.90+0.14) control groups (p<0.05, p<0.001 respectively), serum LH (p<0.05, p<0.001) respectively) and FSH (p<0.05) were significantly higher than normospermic control group. Serum and seminal plasma zinc levels was low in oligospermic, and azoospermic subjects when compared with normospermic control groups (p<0.05, p<0.001 respectively). This suggests its involvement in spermatogenesis and infertility in such patients. Seminal zinc level has weak correlation with testosterone in oligospermic (r=0.44, p<0.05) and with serum zinc in azoospermic

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)

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.

Postoperative follow-up study of patients with differentiated thyroid carcinoma (DTC) is currently based on periodic whole body scan (WBS) and serum thyroglobulin (Tg) assessment. The correlation between Tg levels measured and WB scans of 84 DTC patients is investigated. WBS are performed on a rotation gamma camera DIACAM (Siemens) at 48 and 72 hours after per os administration of 185-222 MBq 131 I. The levels of Tg are determined by IRMA method and kits of BYK, Germany. Normal Tg values are obtained at a control group of 27 patients free of thyroid disease. Increased Tg levels are found at 2 cases (4%) of the group of 50 patients with total thyroidectomy given 131 I without any evidence of recurrences or metastases. At the third group consisting of 18 patients with total thyroidectomy, following 131 I therapy and recurrences and/or metastases, increased Tg values were obtained in 8 cases or 44.4%. Also increased Tg levels were obtained at 4 from 16 patients (25%) subjected to total thyroidectomy but with a residual thyroid tissue proved by scintigraphy. In conclusion, a combination of both methods should be applied for improving the diagnostic and therapeutic results at the postoperative control of DTC patients

OBJECTIVE Progranulin has recently been introduced as a novel adipokine inducing insulin resistance and obesity. In the current study, we investigated renal elimination, as well as association of the adipokine with markers of the metabolic syndrome. RESEARCH DESIGN AND METHODS Progranulin serum levels were quantified by enzyme-linked immunosorbent assay and correlated to anthropometric and biochemical parameters of renal function and glucose and lipid metabolism, as well as inflammation, in 532 patients with stages 1–5 of chronic kidney disease (CKD). RESULTS Median serum progranulin levels adjusted for age, sex, and BMI were significantly different between CKD stages with highest values detectable in stage 5 (stage 1, 58.3 µg/L; stage 2, 63.0 µg/L; stage 3, 65.4 µg/L; stage 4, 68.8 µg/L; and stage 5, 90.6 µg/L). Furthermore, CKD stage was the strongest independent predictor of circulating progranulin in our cohort. In addition, high-sensitivity interleukin-6 and adiponectin remained significantly and independently correlated with the adipokine. CONCLUSIONS We demonstrate that progranulin serum levels increase with deteriorating renal function. These findings are in accordance with the hypothesis that renal clearance is a major elimination route for circulating progranulin. Furthermore, the adipokine is positively and independently associated with markers of inflammation and adiponectin. PMID:23033238

Data from the National Health and Nutrition Examination Survey were used to study trends for urine and serum creatinine over 2001-2014 for those aged ≥20 years. In the absence of chronic kidney disease, levels of urine creatinine decreased for the total population, for those aged 20-29, 50-59, and ≥70 years, for males, and for Mexican Americans and other race/ethnicities. Levels of serum cotinine also exhibited a decreasing trend over 2001-2014 for the total population, for those aged 20-29 and 40-49 years, for females, and for non-Hispanic whites and Mexican Americans. In general, levels of serum creatinine and urine creatinine were positively correlated for chronic kidney disease stages 1-3 and negatively correlated for chronic kidney disease stages 4 and 5.

A hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis has been reported in anorexia nervosa (AN), together with some immunological abnormalities, involving citokine - and particularly Tumor Necrosis-Factor-alpha (TNF-alpha) - production by polymorphonuclear cells. The ability of pro-inflammatory cytokines to activate the HPA axis is well known; however, there are no data demonstrating an interdependence between immunological and endocrine response in AN. To investigate the presence of a correlation between immune response and pituitary-adrenal function, plasma ACTH and serum cortisol concentrations were measured in 13 AN patients and in the same number of controls. TNF-alpha and interleukin (IL)-1beta production by ex-vivo unstimulated and LPS-stimulated peripheral mononuclear cells was also assessed. Circulating cortisol concentrations were higher (p<0.01) in AN (156.7 +/- 45.1 microg/l, mean +/- SD) than in controls (105.9 +/- 25.7 microg/l). Unstimulated IL-1beta release in supernatants of mononuclear cell cultures was slightly but not significantly higher in AN than in controls, while TNF-alpha release was similar in the two groups. A positive correlation was found between IL-1beta concentrations in unstimulated culture supranatants and serum cortisol levels in AN (r=0.782, p=0.002), while in normal subjects there was a trend toward a negative correlation; a slight positive correlation, while not significant, between IL-1beta and plasma ACTH, as well as between TNF-alpha and serum cortisol was also found in AN. These data suggest that the normal relationship between pro-inflammatory cytokines release, particularly IL-1beta, and cortisol secretion is deranged in AN.

Altered progranulin levels play a major role in neurodegenerative diseases, like Alzheimer's dementia (AD), frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS), even in the absence of GRN mutations. Increasing progranulin levels could hereby provide a novel treatment strategy. However, knowledge on progranulin regulation in neurodegenerative diseases remains limited. We here demonstrate that cerebrospinal fluid progranulin levels do not correlate with its serum levels in AD, FTD and ALS, indicating a differential regulation of its central and peripheral levels in neurodegeneration. Blood progranulin levels thus do not reliably predict central nervous progranulin levels and their response to future progranulin-increasing therapeutics.

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.

Objective: To evaluate the variation of serum neuron specific enolase (NSE) and glutathion S transferases (GST) levels in patients with cerebral infarction and its clinical significance. Methods: The serum levels of NSE in cerebral infarction patients were determined with immunoradiometric assay (IRMA), and the serum level of GST were determined by enzyme immuno sandwich assay (ELISA). Results: Serum NSE levels linked in patients were significantly higher (p<0.01) and GST serum levels were significantly lower (p < 0.01) within 3 days after onset of disease than those at two weeks and those in the controls. There was a positive correlation between serum NSE levels and neurological deficit scores (p < 0.001) and a negative correlation with serum GST levels (p < 0.05). There was also a close relationship between the serum NSE levels and the volume of infarction (p < 0.001). Conclusion: There was a close relationship between the Serum levels of NSE, GST and clinical features of Patients in the early stage of cerebral infarction

Full Text Available Background Changes in serum micro nutrients levels affect a number of critically important metabolic processes; these could potentially influence blood counts and ultimately disease presentation in patients with sickle cell anemia (SCA. Objectives To evaluate the influence of serum micro-nutrients levels; zinc, copper, selenium and magnesium on blood counts in steady state SCA patients. Methods A cross sectional study that involved 28 steady state adult SCA subjects. Seven milliliters (mls of blood was collected; 3 mls was for hemoglobin electrophoresis and full blood count determination while 4 mls was for measurement of serum micro nutrients levels, by the atomic absorption spectrophotometry. Correlation between serum micro-nutrient levels and blood counts was done by the Pearson’s linear regression. Ethical approval was obtained from the institutional review board and each participant gave informed consent. All data was analyzed by SPSS software version 20. Results There was a significant correlation between serum copper levels and mean cell hemoglobin (MCH, platelet and lymphocyte counts (r = 0.418; P = 0.02, r = -0.376; P = 0.04 and r = -0.383; P = 0.04, respectively. There were no significant correlations between serum levels of other micro nutrients (selenium, zinc and magnesium and blood counts. Conclusions Copper influences blood count in SCA patients probably by inducing red cell haemolysis, oxidant tissue damage and stimulating the immune system.

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

The serum α 1 -MG, β 2 -MG and other indices of 35 patients with NIDDM and 15 patients with diabetic retinopathy are determined. The results show that not only the serum α 1 -MG, β 2 -MG of all patients are obviously higher than the normal, but the serum α 1 -MG rises earlier than β 2 -MG. By means of correlation analysis, the serum β 2 -MG is significantly correlative with β 2 -MG and Scr(r = 0.673, r = 0.608). All those indicate that the level of the serum α 1 -MG may be a reliable and sensitive index to the diabetic retinopathy in the early diagnosis

Possible Increase in Serum FABP4 Level Despite Adiposity Reduction by Canagliflozin, an SGLT2 Inhibitor.

Directory of Open Access Journals (Sweden)

Masato Furuhashi

Full Text Available Fatty acid-binding protein 4 (FABP4/A-FABP/aP2 is secreted from adipocytes in association with catecholamine-induced lipolysis, and elevated serum FABP4 level is associated with obesity, insulin resistance and atherosclerosis. Secreted FABP4 as a novel adipokine leads to insulin resistance via increased hepatic glucose production (HGP. Sodium-glucose cotransporter 2 (SGLT2 inhibitors decrease blood glucose level via increased urinary glucose excretion, though HGP is enhanced. Here we investigated whether canagliflozin, an SGLT2 inhibitor, modulates serum FABP4 level.Canagliflozin (100 mg/day was administered to type 2 diabetic patients (n = 39 for 12 weeks. Serum FABP4 level was measured before and after treatment.At baseline, serum FABP4 level was correlated with adiposity, renal dysfunction and noradrenaline level. Treatment with canagliflozin significantly decreased adiposity and levels of fasting glucose and HbA1c but increased average serum FABP4 level by 10.3% (18.0 ± 1.0 vs. 19.8 ± 1.2 ng/ml, P = 0.008, though elevation of FABP4 level after treatment was observed in 26 (66.7% out of 39 patients. Change in FABP4 level was positively correlated with change in levels of fasting glucose (r = 0.329, P = 0.044, HbA1c (r = 0.329, P = 0.044 and noradrenaline (r = 0.329, P = 0.041 but was not significantly correlated with change in adiposity or other variables.Canagliflozin paradoxically increases serum FABP4 level in some diabetic patients despite amelioration of glucose metabolism and adiposity reduction, possibly via induction of catecholamine-induced lipolysis in adipocytes. Increased FABP4 level by canagliflozin may undermine the improvement of glucose metabolism and might be a possible mechanism of increased HGP by inhibition of SGLT2.UMIN-CTR Clinical Trial UMIN000018151.

Jin-Chun Lu

Full Text Available This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters.631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH, total testosterone (TT, estradiol (E2 and SHBG levels were detected.Seminal plasma and serum TG, TC and LDL levels were positively related to age. Serum TC, TG and LDL were positively related to obesity-associated markers (P < 0.001, while only seminal plasma TG was positively related to them (P < 0.05. For lipids levels in serum and seminal plasma, only TG level had slightly positive correlation between them (r = 0.081, P = 0.042. There was no significant correlation between serum lipids levels and semen parameters. However, seminal plasma TG, TC, LDL and HDL levels were negatively related to one or several semen parameters, including semen volume (SV, sperm concentration (SC, total sperm count (TSC, sperm motility, progressive motility (PR and total normal-progressively motile sperm counts (TNPMS. Moreover, seminal plasma TG, TC, LDL and HDL levels in patients with oligospermatism, asthenospermia and teratozoospermia were higher than those with normal sperm concentration, motility or morphology. After adjusting age and serum LH, FSH, TT, E2 and SHBG levels, linear regression analysis showed that SV was still significantly correlated with seminal plasma LDL (P = 0.012, both of SC and TSC with seminal plasma HDL (P = 0.028 and 0.002, and both of PR and sperm motility with seminal plasma TC (P = 0.012 and 0.051.The abnormal metabolism of lipids in male reproductive system may contribute to male factor infertility.

Full Text Available To evaluate the role of Cystatin C (Cys-C in tumorigenesis and progression of prostate cancer (PCa, we retrospectively collected the clinical information from the records of 492 benign prostatic hyperplasia (BPH, 48 prostatic intraepithelial neoplasia (PIN, and 173 PCa patients, whose disease was newly diagnosed and histologically confirmed. Pretreatment serum Cys-C levels were compared across the various groups and then analyzed to identify relationships, if any, with clinical and pathological characteristics of the PCa patient group. There were no significant differences in serum Cys-C levels among the three groups (P > 0.05. In PCa patients with normal SCr levels, patient age was correlated with serum Cys-C level (P ≤ 0.001 but did not correlate with alkaline phosphatase (AKP, lactate dehydrogenase (LDH, prostate specific antigen (PSA, Gleason score, or bone metastasis status (P > 0.05. Age and SCr contributed in part to the variations in serum Cys-C levels of PCa patients (r = 0.356, P ≤ 0.001; r = 0.520, P ≤ 0.001. In conclusion, serum Cys-C levels predict renal function in patients with prostate neoplasia, but were not a biomarker for the development of prostate neoplasia, and were not correlated with the clinicopathological characteristics of PCa.

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.

Full Text Available Abstract Background Mammary tumours are the most common malignancy diagnosed in female dogs and a significant cause of mortality and morbidity in this species. Carbohydrate antigen (CA 15–3 is a mucinous glycoprotein aberrantly over-expressed in human mammary neoplasms and one of the most widely used serum tumour markers in women with breast cancer. The aim of this study was to investigate the antigenic analogies of human and canine CA 15–3 and to assess its expression in canine mammary cancer tissues and cell lines. Immunohistochemical expression of CA 15–3 was evaluated in 7 canine mammary cancer cell lines and 50 malignant mammary tumours. As a positive control, the human breast carcinoma cell line MCF7 and tissue were used. To assess CA 15–3 staining, a semi-quantitative method was applied. To confirm the specificity and cross-reactivity of an anti-human CA 15–3 antibody to canine tissues, an immunoblot analysis was performed. We also investigated serum CA 15–3 activity to establish whether its expression could be assigned to several tumour characteristics to evaluate its potential use as a serum tumour marker in the canine mammary oncology field. Results Immunocytochemical analysis revealed CA 15–3 expression in all examined canine mammary cancer cell lines, whereas its expression was confirmed by immunoblot only in the most invasive cells (CMT-W1, CMT-W1M, CMT-W2 and CMT-W2M. In the tissue, an immunohistochemical staining pattern was observed in 34 (68% of the malignant tumours. A high statistical correlation (p = 0.0019 between serum CA 15–3 levels and the degree of tumour proliferation and differentiation was shown, which indicates that the values of this serum marker increase as the tumour stage progresses. Conclusions The results of this study reveal that CA 15–3 is expressed in both canine mammary tumour cell lines and tissues and that serum levels significantly correlate with the histological grade of the

in hypocretin neurons in hypothalamus in post-mortem tissue. 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...

The aim of this study was to assess rheumatoid arthritis (RA) synovitis with positron emission tomography (PET) and 18 F-fluorodeoxyglucose ( 18 F-FDG) in comparison with dynamic magnetic resonance imaging (MRI) and ultrasonography (US). Sixteen knees in 16 patients with active RA were assessed with PET, MRI and US at baseline and 4 weeks after initiation of anti-TNF-α treatment. All studies were performed within 4 days. Visual and semi-quantitative (standardised uptake value, SUV) analyses of the synovial uptake of FDG were performed. The dynamic enhancement rate and the static enhancement were measured after i.v. gadolinium injection and the synovial thickness was measured in the medial, lateral patellar and suprapatellar recesses by US. Serum levels of C-reactive protein (CRP) and metalloproteinase-3 (MMP-3) were also measured. PET was positive in 69% of knees while MRI and US were positive in 69% and 75%. Positivity on one imaging technique was strongly associated with positivity on the other two. PET-positive knees exhibited significantly higher SUVs, higher MRI parameters and greater synovial thickness compared with PET-negative knees, whereas serum CRP and MMP-3 levels were not significantly different. SUVs were significantly correlated with all MRI parameters, with synovial thickness and with serum CRP and MMP-3 levels at baseline. Changes in SUVs after 4 weeks were also correlated with changes in MRI parameters and in serum CRP and MMP-3 levels, but not with changes in synovial thickness. (orig.)

Incapacitating symptom burden in cancer patients contributes to poor quality of life (QOL) and can influence treatment outcomes because of poor tolerance to therapy. In this study, the role of circulating cytokines in the production symptoms in cancer patients is evaluated. Eighty patients with metastatic colorectal cancer with either normal (group I, n = 40) or dampened (group II, n = 40) 24-hour rest/activity patterns measured by actigraphy were identified. Actigraphy patterns were correlated with QOL indices, serum cortisol obtained at 8:00 a.m. and 4:00 p.m. and with serum levels of transforming growth factor-alpha, tumor necrosis factor-alpha, and interleukin 6 (IL-6) obtained at 8:00 a.m. and analyzed in duplicate by ELISA. Cytokine levels and survival were also correlated. Group II patients had significantly higher pre treatment levels of all three cytokines, displayed significantly poorer emotional and social functioning, had higher fatigue, more appetite loss, and poorer performance status compared with group I patients. Transforming growth factor-alpha (TGF-alpha) and IL-6 were significantly increased in the patients with WHO performance status >1 and in those with appetite loss. Fatigue was significantly associated with elevated TGF-alpha only. IL-6 was increased in those patients with extensive liver involvement and multiple organ replacement, and it was significantly correlated with dampened cortisol rhythm. In a multivariate analysis, IL-6 was correlated with poor treatment outcome. Significant correlations were found between serum levels of TGF-alpha and IL-6, circadian patterns in wrist activity and serum cortisol and tumor-related symptoms in patients with metastatic colorectal cancer. These data support the hypothesis that some cancer patient's symptoms of fatigue, poor QOL, and treatment outcome are related to tumor or host generated cytokines and could reflect cytokine effects on the circadian timing system. This interplay between cytokine

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

Full Text Available BackgroundMany studies reported that copper, zinc and magnesium play important roles in the pathogenesis and development of neonatal hyperbilirubinemia. Exchange transfusion and intensive phototherapy are known two modalities of therapy for severe neonatal hyper bilirubinemia, but the effect of them on those trace elements is unknown.Materials and MethodsCopper, Zinc and Magnesium serum levels were measured before and after treatment with intensive phototherapy and exchange transfusion in full term neonates with indirect hyperbilirubinemia admitted to neonatal intensive care unit (NICU of Minia and Sohag University hospitals, Egypt, during 2014-2016 and comparison with normal healthy neonates was done.ResultsThere were significant higher copper and magnesium and lower zinc serum levels in neonates with indirect hyperbilirubinemia than controls before and after intensive phototherapy. These levels were significantly changed after exchange transfusion to be comparable with controls. Significant positive correlations between the total bilirubin levels and hemoglobin, copper, and magnesium serum levels and significant negative correlations with serum zinc levels were present. There were no significant correlations between maternal and neonatal copper, zinc or magnesium serum levels.ConclusionNeonates with indirect hyperbilirubinemia had significant higher copper and magnesium and lower zinc serum levels than healthy neonates which were not related to their maternal serum levels. Intensive phototherapy had no effect on their levels while exchange transfusion changed these levels to be comparable with that of normal healthy neonates.

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

Full Text Available Background Nephrotic syndrome (NS patients frequently have abnormalities in calcium metabolism that manifest as hypocalcemia and reduced intestinal absorption of calcium. Hypocalcemia is initially attributed to hypoalbuminemia but it may also relate to a low level of ionized calcium. The ionized calcium level depends on the severity and duration of proteinuria. Objective To assess the rel ationship between ionized calcium and serum albumin level in idiopathic NS children. Methods An analytical study with cross-sectional design was applied to NS and healthy children between 1-14 years old in the Child Health Department of Hasan Sadikin Hospital, Bandung from December 2009 to April 2010. Ionized calcium was examined by Ca2 + analyzer AVL 980 with ion-selective electrodes (ISE methods. Results A total of34 subjects were recruited, consist of 17 NS and 17 healthy children. The mean ionized calcium and serum albumin level in NS children was 4.56 (SD 0.23 mg/dLand 1.45 (SD 0.24 g/dL, respectively. Statistical difference between ionized calcium level in NS and in healthy children was significant (P<0.05. Pearson correlation test between ionized calcium and serum albumin was significant (P<0.05 with correlation coefficient (r 0.53. We found the following equation to estimate ionized calcium (y based on the serum albumin level (x: y=3.84+0.49x. Conclusion There is a moderately positive linear relationship between ionized calcium and serum albumin level in NS children.

Full Text Available Plasma FGF-23 concentrations and its relationship with calcium-phosphate homeostasis were evaluated in 48 perimenopausal obese women and in 29 nonobese controls. Serum parathyroid hormone, 25-hydroxyvitamin D3, CTX1, osteocalcin, total calcium, phosphorus, creatinine, and plasma intact FGF-23 concentrations were assessed. DXA of lumbar spine and femoral neck was performed to determine bone mineral density (BMD. Plasma iFGF-23 concentration was significantly higher in obese patients (by 42% and correlated with age and BMD of proximal femur (R=-0.346; R=0.285, resp. but not with markers of bone turnover. However, serum phosphorus level in obese subjects was significantly lower. iFGF-23 concentration correlated significantly with body mass index (R=0.292 and fat content (R=0.259 in all study subjects. Moreover, a significant correlation between iFGF-23 and iPTH (R=0.254 was found. No correlation between serum phosphorus or eGFR and plasma iFGF-23 and between eGFR and serum phosphorus was found. Elevated serum iFGF-23 concentration may partially explain lower phosphorus levels in the obese and seems not to reflect bone turnover.

The aim of our study was to measure and compare serum insulin-like growth factor-1 (IGF-1) levels at postmenstrual age of 33 weeks between preterm infants with and without retinopathy of prematurity (ROP). ROP occurs in two phases. Low serum levels of IGF-1 during ROP phase 1 have been found to correlate with the severity of ROP. ROP phase 2 begins around postmenstrual week 33. We conducted a prospective cohort study to measure serum IGF-1 levels in premature infants at postmenstrual age of 33 weeks. The study included all premature infants (N = 74), gestational age large controlled study with repeated measurement of IGF-1 level in the neonatal period is needed to confirm that restoration of IGF-I level occurs in ROP phase 2, i.e. that the low level of IGF-1 is only a feature of ROP phase 1.

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

Myostatin, a member of the transforming growth factor-β family, contributes to joint deterioration in mice. Thus, we aimed to assess the correlation of myostatin concentrations with the presence and severity of knee osteoarthritis (OA). We determined serum and synovial fluid (SF) myostatin concentrations in a population of 184 patients with knee OA and 109 healthy controls. The knee OA group presented with higher serum myostatin concentrations than the controls. Knee OA patients with KL grade 4 showed higher serum and SF myostatin concentrations compared with those with KL grade 2 and 3. Knee OA patients with KL grade 3 had higher serum and SF myostatin concentrations compared with those with KL grade 2. Serum and SF myostatin concentrations were significantly correlated with KL grading. Serum and SF myostatin concentrations were correlated with the presence and severity of knee OA. © 2016 Wiley Periodicals, Inc.

Full Text Available Aims. We evaluated the links between leptin and visfatin levels and fertilization rates in nonoverweight (NOW women with PCOS (NOW-PCOS from Apulia undergoing in vitro fertilization/embryo transfer (IVF. Materials and Methodology. We recruited 16 NOW women with PCOS (NOW-PCOS and 10 normally ovulating NOW women (control-NOW. All women underwent IVF. Androgens, 17-β-estradiol (17β-E2, and insulin levels were measured in plasma and/or serum and leptin and visfatin levels were assayed in both serum and follicular fluid (FF-leptin, FF-visfatin. Results. In NOW-PCOS, both serum and FF-leptin were significantly lower than in control-NOW. In NOW-PCOS, significant correlations were found between BMI and serum leptin and insulinemia and FF-leptin. By contrast, in control-NOW, FF-leptin levels were not correlated with insulinemia. Serum visfatin levels were not significantly different in NOW-PCOS and control-NOW, but FF-visfatin levels were 1.6-fold higher, although not significantly, in NOW-PCOS than in control-NOW. Conclusions. Both serum leptin levels and FF-leptin are BMI- and insulin-related in Southern Italian NOW-PCOS from Apulia. In line with other reports showing that FF-leptin levels are predictive of fertilization rates, lower than normal FF-leptin levels in NOW-PCOS may explain their lower fertilization rate and this may be related to the level of insulin and/or insulin resistance.

Differences in small solutes transport rate (SSTR) during peritoneal dialysis (PD) may affect water and solutes removal. Patients with high SSTR must rely on shorter dwell times and increased dialysate glucose concentrations to keep fluid balance. Glucose absorption during peritoneal dialysis (PD), besides affecting glucose and insulin metabolism, may induce weight gain. The study aimed at examining acute glucose and insulin serum level changes and other potential relationships in PD patients with diverse SSTR. This cross-sectional study used a modified peritoneal equilibration test (PET) that enrolled 34 prevalent PD patients. Zero, 15, 30, 60, 120, 180, and 240-minute glucose and insulin serum levels were measured. Insulin resistance index was assessed by the homeostasis model assessment (HOMA-IR) formula. SSTR categories were classified by quartiles of the four-hour dialysate/serum creatinine ratio (D(4)/P(Cr)). Demographic and clinical variables were evaluated, and the body mass index (BMI) was estimated. Correlations among variables of interest and categories of SSTR were explored. Glucose serum levels were significantly different at 15, 30, and 60 minutes between high and low SSTR categories (p = 0.014, 0.009, and 0.022). Increased BMI (25.5 +/- 5.1) and insulin resistance [HOMA-IR = 2.60 (1.40-4.23)] were evidenced overall. Very strong to moderate correlations between insulin levels along the PET and HOMA-IR (r = 0.973, 0.834, 0.766, 0.728, 0.843, 0.857, 0.882) and BMI (r = 0.562, 0.459, 0.417, 0.370, 0.508, 0.514, 0.483) were disclosed. CONCLUSIONS; Early glucose serum levels were associated with SSTR during a PET. Overweight or obesity and insulin resistance were prevalent. An association between insulin serum levels and BMI was demonstrated.

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)

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

Tartrate-resistant phosphatase isoform 5a is expressed in tumor-associated macrophages and is a biomarker of chronic inflammation. Herein, we correlated serum tartrate-resistant phosphatase isoform 5a levels with metabolic syndrome status and made comparisons with traditional markers of inflammation, including c-reactive protein and interleukin-6. One hundred healthy volunteers were randomly selected, and cut-off points for metabolic syndrome related inflammatory biomarkers were determined using receiver operating characteristic curves. Linear and logistic regression models were subsequently used to correlate inflammatory markers with the risk of metabolic syndrome. Twenty-two participants met the criteria for metabolic syndrome, and serum tartrate-resistant phosphatase isoform 5a levels of >5.8 μg/L were associated with metabolic syndrome (c-statistics, 0.730; p = 0.001; 95% confidence interval, 0.618-0.842). In addition, 1 μg/L increases in tartrate-resistant phosphatase isoform 5a levels were indicative of a 1.860 fold increase in the risk of metabolic syndrome (p = 0.012). Elevated serum tartrate-resistant phosphatase isoform 5a levels are associated with the risk of metabolic syndrome, with a cut-off level of 5.8 μg/L.

The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease.

Full Text Available Objective: To investigate the correlation of the carotid intima-media unevenness and stiffness with serum illness indexes in patients with type 2 diabetes mellitus. Methods: A total of 118 patients with type 2 diabetes mellitus who were treated in this hospital between February 2016 and August 2017 were selected as the diabetes group, and 100 healthy volunteers who received physical examination in this hospital during the same period were selected as normal control group. The differences in carotid intima-media unevenness and stiffness levels as well as serum levels of insulin resistance indexes and inflammatory adipocytokines were compared between the two groups of subjects. Pearson test was used to assess the correlation between carotid intima-media parameter levels and above serum illness index levels in patients with type 2 diabetes mellitus. Results: IMIsqrt and PWV levels in diabetes group were higher than those in normal control group; serum FINS and IRI levels were higher than those in normal control group whereas ISI level was lower than that in normal control group; serum APN content was lower than that in normal control group whereas LEP and SAA contents were higher than those in normal control group. Pearson test showed that the IMIsqrt and PWV levels in patients with type 2 diabetes mellitus were directly correlated with serum insulin resistance index levels and inflammatory adipocytokine contents. Conclusion: Carotid intima-media unevenness and stiffness both increase in patients with type 2 diabetes mellitus, and could objectively reflect the insulin resistance and systemic micro-inflammatory state.

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

Psoriasis has been considered as systemic disorder. Lipocalin-2 might be a link between psoriasis and its comorbidities. Aim of the study was to investigate the associations between serum lipocalin-2 levels and the disease activity, markers of inflammation or metabolic disturbances and changes after topical treatment in psoriatic patients. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were recruited. Blood samples were collected before and after 14 days of therapy. Serum lipocalin-2 concentrations were examined by enzyme-linked immunosorbent assay. The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and with effectiveness of topical treatment. Lipocalin-2 serum levels were significantly increased in psoriatic patients in comparison to the controls (p = 0.023). No significant correlations with indicators of inflammation, nor BMI or PASI were noted. A statistical association between lipocalin-2 and low-density lipoprotein-cholesterol was shown. After topical treatment serum lipocalin-2 level did not significantly change (p = 0.9), still remaining higher than in the controls, despite clinical improvement. Lipocalin-2 might be a marker of psoriasis and convey cardiovascular or metabolic risk in psoriatic patients, but may not be a reliable indicator of inflammation, severity of psoriasis nor efficacy of antipsoriatic treatment.

Objective We aimed to evaluate the association between serum uric acid levels at the onset and prognostic outcome in patients with acute ischaemic stroke. Methods We retrospectively analysed the outcomes of 1166 patients with ischaemic stroke who were hospitalized in our centre during August 2008 to November 2012. Correlations of serum uric acid levels and prognostic outcomes were analysed. Results Men had higher serum uric acid levels and better neurological functional outcomes compared with women. There was a strong negative correlation between serum uric acid levels and unfavourable neurological functional outcomes. Generalized estimated equation analysis showed that a higher serum uric acid level (>237 µmol/L) was a protective factor for neurological functional outcome in male, but not female, patients. Among five trial of ORG 10172 in acute stroke treatment classification subtypes, only patients with the large-artery atherosclerosis subtype had a significant protective effect of serum uric acid levels on neurological outcome. Conclusions Our study shows that high serum uric acid levels are a significant protective factor in men and in the large-artery atherosclerosis subtype in patients with ischaemic stroke. This is helpful for determining the prognostic value of serum uric acid levels for neurological outcome of acute ischaemic stroke.

Cystatin C (CysC) is a renal function marker that is not as influenced as creatinine (Cr) by endogenous or exogenous agents, so it is therefore proposed as a marker in preterm infants. To determine serum CysC values in preterm infants during the first week of life, compared to Cr. To analyze alterations caused by prematurity diseases. The design involved a longitudinal, observational study of prospective cohorts. Groups were based on gestational age (GA): Group A (24-27 weeks), Group B (28-33 weeks), Group C (34-36 weeks). Blood samples were collected at birth, within 48-72hours and after 7 days of life. SPSS v.20 software was used. The statistical methods applied included chi-squared test and ANOVA. A total of 109 preterm infants were included in the study. CysC levels were: 1.54mg/L (±0.28) at birth; 1.38mg/L (±0.36) within 48-72hours of life; 1.50mg/L (±0.31) after 7 days (p<0.05). Cr levels were: 0.64mg/dL (±0.17) at birth; 0.64mg/dL (±0.28) within 48-72hours; 0.56mg/dL (±0.19) after 7 days (P<.05). CysC values were lower in hypotensive patients and those with a respiratory disease (P<.05), and no alterations associated with other diseases were observed. There were no differences in Cr levels associated with any disease. Creatinine levels were higher in patients ≤1.500g (P<.05). Serum CysC decreased within 48-72hours of life, and this decline showed significance (P<.05). The levels increased after 7 days in all 3 GA groups, and there was no difference in CysC levels among the groups. More studies in preterm infants with hypotension and respiratory disease are required. CysC is a better glomerular filtration (GF) marker in ≤1.500g preterm infants. Copyright © 2015 The Authors.

The aim of this study was to compare serum brain-derived neurotrophic factor (BDNF) levels between adolescents that harm themselves, those that receive psychiatric treatment but do not harm themselves, healthy adolescents, and childhood traumas and to investigate the relationship between traumatic experiences and serum BDNF levels. The cases were divided into two groups of 40 adolescents exhibiting self-harm behavior (self-harm/diagnosed group) and 30 adolescents receiving psychiatric treatment but not exhibiting self-harm behaviors (non self-harm/diagnosed group). The control group (healthy control group) consisted of 35 healthy adolescents with no psychiatric disorders or self-harm behaviors. The adolescents were asked to fill in the Inventory of Statements About Self Injury (ISAS) and Childhood Trauma Questionnaire (CTQ). For BDNF measurement, blood samples were taken from the cases and controls. The serum BDNF level of self-harming adolescents who used the self-cutting method was significantly lower than that of other groups, and serum BDNF levels decreased with the increase in the emotional neglect and abuse severity of self-harming adolescents during childhood. In our study, serum BDNF levels decreased with the increase in emotional abuse in self-harming adolescents. This finding may indicate that neuroplasticity can be affected by a negative emotional environment during the early period. Copyright © 2017 Elsevier B.V. All rights reserved.

Oral cancer is currently the most frequent cause of cancer-related deaths, which is usually preceded by oral pre-cancerous lesions and conditions. Altered glycosylation of glycoconjugates, such as sialic acid, fucose, etc. are amongst the important molecular changes that accompany malignant transformation. The purpose of our study was to evaluate usefulness of serum Total Sialic Acid (TSA) and serum Lipid-Bound Sialic Acid (LSA) as markers of oral precancerous lesions and histopathologically correlating them with grades of epithelial dysplasia. Blood samples were collected from 50 patients with oral precancer (Leukoplakia & OSMF), 25 patients with untreated oral cancer and 25 healthy subjects. Serum sialic acid (total and lipid bound) levels were measured spectrophotometrically. Tissue samples from all the patients were evaluated for dysplasia. Serum levels of total and lipid bound sialic acid were significantly elevated in patients with oral precancer and cancer when compared with healthy subjects. Analysis of variance test documented that there is progressive rise in serum levels of sialic acid with the degree of dysplastic changes in oral precancer patients. We observed positive correlation between serum levels of the markers and the extent of malignant disease (TNM Clinical staging) as well as histopathological grades. The results suggested that serum levels of TSA and LSA progressively increases with grades of dysplasia in precancerous groups and cancer group, when compared with healthy controls. These glycoconjugates, especially LSA has the clinical utility in indicating a premalignant change.

Due to relatively high concentrations of immunoglobulins, colostrum has the potential to improve the sensitivity of diagnostic tests for diseases in pigs when compared with serum. It is possible that colostrum could improve the sensitivity of the antibody enzyme-linked immunosorbent assay (ELISA) compared with serum. Colostrum is also essential for piglets, providing protection against infections in the first few weeks and months of life. The sensitivity of 2 commercially available ELISAs, one for the detection of Erysipelothrix rhusiopathiae and the second for Mycoplasma hyopneumoniae antibodies, when used with sow colostrum in comparison with serum was investigated. The correlation of maternal E. rhusiopathiae- and M. hyopneumoniae-specific antibody levels with specific-antibody serum levels in the piglet was also determined. The sensitivity was defined as the proportion of vaccinated sows that were correctly identified as vaccinated at a given cutoff point. The true disease status of the sows with regard to the 2 infections was unknown. Blood and colostrum samples were collected from 20 sows, 10 primiparous and 10 multiparous, and blood samples were also collected from the piglets of each sow, 48-72 hr post-farrowing. The sensitivities of both ELISAs were significantly improved when using colostrum compared with serum. Sow serum and colostrum optical density (OD) values were significantly correlated. The mean sow OD values for serum for E. rhusiopathiae and M. hyopneumoniae and colostrum for E. rhusiopathiae were significantly correlated with piglet serum OD levels. If the improved sensitivity of colostrum can be demonstrated in infected animals, this will increase the ability of the test to identify infected animals using both individual and pooled colostrum. Testing serum and/or colostrum using ELISA can be useful predictors of piglet disease-specific OD values. © 2015 The Author(s).

Lamotrigine has acute antidepressant effects in patients with bipolar disorder. However, there is little information regarding appropriate serum levels of lamotrigine and the time until remission after the start of lamotrigine therapy in patients with bipolar II depression. This was a naturalistic and unblinded prospective pilot study. Twelve patients' depressive symptoms were evaluated using the Montgomery-Åsberg Depression Rating Scale (MADRS) at the start of treatment and at the time of remission, and blood samples were obtained at the time of remission. Mahalanobis distance was used to analyze the relationship between the MADRS improvement rate and the serum lamotrigine level. Furthermore, we calculated the Spearman's rank correlation coefficient for the relationship between the MADRS improvement rate and the serum lamotrigine level, and produced box plots of the serum lamotrigine level at remission and the time until remission. The Mahalanobis distance for the patient that was co-administered lamotrigine and valproic acid differed significantly from those of the other patients (p<0.001). There was no linear relationship between the serum lamotrigine level and the MADRS improvement rate among the patients that did not receive valproic acid. The median time from the start of lamotrigine therapy until remission was 6 weeks. The serum lamotrigine level does not have an important impact on the acute therapeutic effects of lamotrigine on bipolar II depression. In addition, we consider that different treatment options should be considered for non-responders who do not exhibit any improvement after the administration of lamotrigine for approximately 6 weeks.
