    Full Text Available Background. Atherogenic lipoproteins, such as total cholesterol, LDL cholesterol, oxidized low density lipoprotein, and triglycerides, are associated with progression of retinopathy. Aim. To evaluate the relationship between lipoprotein(a and retinopathy in patients with type 2 diabetes mellitus. Materials and Methods. We enrolled 145 diabetic consecutive patients (82 females, 63 males; mean age 66.8±12 years, mean duration of diabetes 9.4±6.8 years. Presence and severity of retinopathy were evaluated. Serum lipid profile, including Lp(a level, was assessed. Results. High Lp(a levels have been observed in 54 (78.3% subjects and normal levels in 13 (18.85% subjects as regards diabetic patients with retinopathy. Lp(a levels were high in 15 subjects (21.75% and normal in 63 subjects (91.35% as regards patients without retinopathy. Conclusions. Lp(a levels are increased in a significant percentage of patients with retinopathy compared to diabetic patients without retinopathy. The impact of Lp(a levels on diabetic retinopathy needs to be further investigated.

    Weight gain is a common adverse effect associated with the use of most typical and atypical antipsychotic. Aim of this study was to investigate serum prolactin, leptin, cholesterol, triglyceride, lipoproteins, such high density lipoprotein (HDL), and low density lipoprotein (LDL) levels in patients with Parkinson's disease (PD)-related psychosis during long-term medication with atypical antipsychotic. The study population comprised 40 patients, who were divided into 4 groups: olanzapine (n=10), risperidone (n=10), seroquel (n=10) monotherapy, a group of 10 patients receiving only antiparkinson drugs and a control group of 8 healthy persons. The patients were evaluated at baseline and at the sixth and twelfth week according to the Positive and Negative Syndrome Scale (PANSS), body mass index (BMI), and fasting serum prolactin, leptin, lipids and lipoproteins levels. Treatment of patients with olanzapine caused marked increase of serum LDL, cholesterol, triglyceride, and leptin levels (prelationship between serum leptin, lipid levels and BMI. However, treatment of patients with seroquel did not cause changes in serum prolactin, leptin, lipids, and lipoproteins levels. Our results suggest that treatment of patients with PD-related psychosis with seroquel appears to have minimal influence on serum leptin, prolactin, lipids, lipoproteins and BMI compared with olanzapine and risperidone.

    Objective: To investigate the relationship between changes of serum lipoprotein (a) levels and development of stroke. Methods: Lipoprotein (a) levels were determined with ELISA in 100 patients with stroke and 60 controls. Results: The serum LP (a) levels in patients with stroke complicated with diabetes were also significantly higher than those in patients with stroke but without diabetes (P<0.01). Conclusion: The levels of serum LP(a) was a relatively independent risk factor, and it could be of some prognostic value. (authors)

    BACKGROUNDS/AIM: The aim of the study was to determine serum lipids and oxidized low density lipoprotein (ox-LDL) levels in preeclamptic pregnants and compare with those of normotensives. Ox-LDL levels were determined by enzyme linked immunosorbent assay (ELISA); total cholesterol, hight density lipoprotein (HDL)-cholesterol and triglyceride levels were measured by enzymatic colorimetric assay in 26 normotensive and 27 preeclamptic pregnants. LDL and very low density lipoprotein (VLDL) cholesterol was calculated by Friedwald formula. Serum levels of Ox-LDL (U/L), total-cholesterol (mg/dL), HDL-cholesterol (mg/dL), LDL-cholesterol (mg/dL), triglyceride (mg/dL), and VLDL-cholesterol (mg/dL) in normotensive and preeclamptic pregnants were found as 130±60 and 133±69; 248±49 and 248±81; 67±14 and 61±16; 147±61 and 135±59; 207±76 and 256±87; 41±15 and 50±17, respectively. Mean values of Ox-LDL and other lipid parameters were higher than the upper limits of their reference ranges in both of groups. However no significant differences were found in Ox-LDL, total, HDL and LDL-cholesterol levels between two groups. However, the levels of triglyceride and VLDL-cholesterol were significantly higher in preeclampsia group. The present results suggest that the levels of serum Ox-LDL and other lipid parameters rise as a result of pregnancy rather than as a result of preeclampsia.

    For a better understanding of the relationship between lipid peroxide (LPO) and vascular diseases, the author determined LPO levels and lipid contents of serum lipoprotein fractions of diabetics with angiopathy. The LPO level in high density lipoprotein (HDL) fraction of diabetic serum was significantly higher than that of normal serum whereas no significant increase was observed in the levels of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions of diabetic serum. As to the ratios of LPO to total lipids in these lipoprotein fractions, it was found that the ratio in HDL fraction of the diabetics was markedly higher than that of the normals. These results suggest that the increase in LPO levels in the sera of diabetic patiens is due to that in HDL fraction. To study further this problem, the author employed 60 Co-irradiated rabbit as a model, since it was already reported that radiation affects lipid metabolism and LPO formation, and that it induces the development of atherosclerosis. Upon irradiation with 60 Co ranging from 100R to 700R, serum LPO level of rabbit was significantly increased. Although elevation of LPO level was found in each serum lipoprotein fraction of VLDL, LDL and HDL, LPO level per lipid content was significantly increased only in HDL fraction. In the irradiated rabbit, significant elevation of the level of LPO was also observed in the liver, while no significant increase was found in the kidney and spleen. These results indicate that high level of LPO observed in the serum of irradiated rabbit would be the reflection of the increased LPO in the liver. (J.P.N.)

    Full Text Available This study was carried out to investigate the relationship between lipoprotein (a levels and the development of atherosclerosis in chronic renal failure (CRF patients with the possible role of the liver. Serum Lp (a levels were measured in samples from 20 CRF patients on hemodialysis (HD, 20 liver cirrhosis (LC patients, 20 patients having both CRF and LC and undergoing HD, and 20 normal control subjects. Renal function (blood urea nitrogen (BUN and creatinine, hepatic function (transaminases (ALT and AST, alkaline phosphatase (ALP and total bilirubin investigations and serum cholesterol were carried out for all the subjects enrolled in this study. Serum Lp (a concentration in CRF patients without LC was 87.25 ± 6.17 mg/dl, which was significantly higher than all the investigated groups (P < 0.001. Lp(a concentration in patients with both CRF and LC was 24.65 ± 1.98 mg/dl, which was not significantly different from the controls, but was significantly higher than that in the subjects with LC only (P < 0.001 where the latter group had significantly low Lp (a values (11.1 ± 0.99 relative to all the other groups (P < 0.001. Lp (a correlated positively with cholesterol in all groups except the LC subjects, but did not correlate with age, or renal function in both CRF groups.

    Full Text Available Background: Elevated serum levels of oxidized Low-density Lipoprotein (oxLDL have been found in type 2 and in poorly controlled diabetic patients. Gestational diabetes mellitus (GDM has common features with type 2 diabetes. Objective: The aim of our study was to evaluate the serum levels of oxLDL in women with GDM compared to normal pregnant women. Materials and Methods: In this cross-sectional study, ninety-two subjects were randomly allocated to either GDM (n=46 or control (n=46 groups matched for age, body mass index and parity from March 2013 to March 2014. GDM was diagnosed according to the American Diabetes Association criteria at 24-26 weeks of gestation. OxLDL was measured using enzyme-linked immunosorbent assay. T-test and Pearson correlation coefficients were applied for analyzing the data by using SPSS version 17. Results: Compared to the controls, significantly higher oxLDL levels were found in the GDM group (17.16 ± 3.71 U/L vs. 8.77 ± 1.84 U/L, respectively, p < 0.001. No significant correlations were found between oxLDL and age and BMI of the patients in the groups. Conclusion: Our study found significant increase of oxLDL in GDM emphasizing the role of short-term hyperglycemia in the formation of oxLDL during GDM. The importance of aptly diagnosis of GDM in maternal health may also be concluded.

    Full Text Available OBJECTIVE: To identify the association between food group consumption frequency and serum lipoprotein levels among adults. METHODS: The observations were made during a cross-sectional survey of a representative sample of men and women over 20 years old living in Cotia county, S. Paulo, Brazil. Data on food frequency consumption, serum lipids, and other covariates were available for 1,045 adults. Multivariate analyses adjusted by age, gender, body mass index, waist-to-hip ratio, educational level, family income, physical activity, smoking, and alcohol consumption were performed. RESULTS: Consumption of processed meat, chicken, red meat, eggs and dairy foods were each positively and significantly correlated with LDL-C, whereas the intake of vegetables and fruits showed an inverse correlation. Daily consumption of processed meat, chicken, red meat, eggs, and dairy foods were associated with 16.6 mg/dl, 14.5 mg/dl, 11.1 mg/dl, 5.8 mg/dl, and 4.6 mg/dl increase in blood LDL-C, respectively. Increases of daily consumption of fruit and vegetables were associated with 5.2 mg/dl and 5.5 mg/dl decreases in LDL-C, respectively. Alcohol beverage consumption showed a significant positive correlation with HDL-C. CONCLUSIONS: Dietary habits in the study population seem to contribute substantially to the variation in blood LDL and HDL concentrations. Substantially CHD risk reduction could be achieved with dietary changes.

    To investigate the relationship between polymorphism of Ghrelin gene and serum levels of lipoprotein in Han Chinese with or without coronary heart disease (CHD) risk factors. PCR restriction fragment length polymorphism assay was used to detect the distribution of genotypes of Ghrelin gene in 225 Han Chinese (40 to 69 years-old) with CHD risk factors, 78 subjects without CHD risk factors served as normal controls. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and very low-density lipoprotein (VLDL) were measured to analyze the relationship with the polymorphism of Ghrelin gene. Ghrelin genotype frequencies of AA, AG, GG (0.975, 0.025, 0.00 in control group and 0.956, 0.040, 0.004 in the high-risk group, all P > 0.05) as well as the allele frequencies of A, G (0.987, 0.013 in control group and 0.976, 0.024 in the high-risk group, all P > 0.05) were similar between the groups. HDL-C levels of the Arg/Gln carriers were significantly lower than those of Arg/Arg carriers in control group and in the high-risk group (all P < 0.05). Arg/Gln carriers were associated lower HDL-C levels in Han Chinese.

    Triglycerides in fat emulsions are hydrolyzed by lipoprotein lipase only when they are "activated" by serum lipoproteins. The contribution of different lipoprotein fractions to hydrolysis of triglycerides in soybean oil emulsion was assessed by determining the quantity of lipoprotein fraction required to give half-maximal hydrolysis. Most of the activator property of whole serum from normolipidemic, postabsorptive subjects was in high density lipoproteins. Low density lipoproteins and serum from which all lipoprotein classes were removed had little or no activity. Also, little activator was present in guinea pig serum or in very low density poor serum from an individual with lecithin:cholesterol acyltransferase deficiency, both of which are deficient in high density lipoproteins. Human very low density lipoproteins are potent activators and are much more active than predicted from their content of high density lipoprotein-protein. Per unit weight of protein, very low density lipoproteins had 13 times the activity of high density lipoproteins. These observations suggest that one or more of the major apoproteins of very low density lipoproteins, present as a minor constituent of high density lipoproteins, may be required for the activation process.

    Full Text Available Lipoprotein (a (Lp(a which is a low-density lipoprotein-like particle containing apo(a is considered as an emergent cardiovascular risk factor. Type 2 diabetes mellitus (T2DM is associated with a two- to threefold increase in the risk of cardiovascular disease (CVD. The aim of this study was to investigate the levels of Lp(a in Black South African T2DM patients and its association with other metabolic factors. 67 T2DM patients and 48 healthy control participants were recruited for the cross-sectional study. The Lp(a level was determined by ELISA and the result was analyzed using SPSS. The Lp(a level in diabetics was found to be significantly increased (P=0.001 when compared to the normal healthy group. In the diabetic group, the Lp(a levels correlated significantly with the duration of diabetes (P=0.008 and oxidized LDL (ox-LDL levels (P=0.03 and decreased total antioxidant capacity (P=0.001. The third tertile of Lp(a was significantly correlated with increased ox-LDL, C-reactive protein, and triglycerides and decreased total antioxidant capacity.

    Oxidative stress (OS) is involved in the pathogenesis of atherosclerosis. Hyperbaric oxygen therapy (HBOT), in which 100% oxygen is inhaled under hyperbaric pressure, may create OS. Therefore, the aim of this research was to measure the serum oxidized low-density lipoprotein (oxLDL) level in patients undergoing HBOT. Twenty-nine patients who underwent HBOT to treat various diseases were enrolled in this study. The serum oxLDL level was measured at the beginning of the first and after the 10th therapy session. There was no significant difference between the oxLDL level of patients before and after HBOT (4.96±0.1 vs. 4.94±0.1 U/mL; p=0.36). HBOT seems to be safe in terms of oxLDL production up to 10 sessions. However, further large-scale studies investigating longer duration of HBOT treatment are required to understand the role of OS.

    To investigate the hypercholesterolemic effects of a dietary exchange between 16:0 and 18:1 while 18:2 was at relatively lower level (approximately 4%) in aged women with initially high total serum cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) values and with high intakes of dietary cholesterol. Subjects were assigned to two consecutive 28 d periods. In the first period all subjects followed an oleic acid-rich diet in the form of oleic acid-rich sunflower oil. This was followed by a second period rich in palmitic acid in the form of palmolein. Nutrient intakes, serum lipids, lipoproteins, antioxidant vitamins, peroxides and LDL-peroxides were measured at two dietary periods. Instituto de Nutrición y Bromatología (CSIC), Departamento de Nutrición y Bromatología I (Nutrición) and Sección Departamental de Quimica Analítica, Universidad Complutense, Madrid, Spain. The palmolein period led to an increase in TC (P or = 6.21 mmol/L or with TC 6.21 mmol/L than in women with TC < 6.21 mmol/L, but palmolein decreased serum and LDL-peroxide in hypercholesterolemics more than in the normocholesterolemics, resulting in serum and LDL-peroxide levels which theoretically are more adequate. Though palmolein increased LDL-C concentrations, it better protected LDL particles, mainly in women with high TC, against peroxidation than did oleic acid-rich sunflower oil.

    Full Text Available Diabetes mellitus is an important problem amongst human and animals. In veterinary medicine too, diabetes mellitus occurs in many animals particularly household pets. This study was conducted in order to evaluate the effect of date consumption on serumic levels of glucose, triglyceride, cholesterol, LDL, VLDL and HDL in rats suffering from experimental diabetes mellitus. Thirty male wistar rats with the age of 8 weeks and mean body weight of 200±20 gr were selected and divided into 5 groups so that there were 6 rats per group. The groups consisted of day one healthy control, final day healthy control, healthy treatment consuming date, diabetic treatment consuming date and diabetic control group. Diabetic treatment and control groups received 100 mg/kg of alloxan subcutaneously to create experimental diabetes. The two healthy control groups also received equal amounts of normal saline solution subcutaneously. The injections were repeated a week later in all groups. After observing the diabetes symptoms including polydipsia, polyuria, glucosuria and hyperglycemia in groups that were given alloxan, feeding of healthy and diabetic treatment groups with equal ratio of date and pellet was initiated. Final day healthy control group and diabetic control group were fed only with pellet. The groups were fed for 10 days following the start of diabetes symptoms. Blood samples were collected from all groups on day 10. Evaluation of the serumic levels of glucose, cholesterol and LDL revealed statistically significant increase in diabetic control group in comparison with the healthy control groups and also in healthy and  diabetic treatment groups consuming date as compared with diabetic control and healthy groups (p

    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 assess the relationship of serum total homocysteine (tHcy) and lipoprotein (a) [Lp(a)] levels with systemic hypertension, Diabetes mellitus and smoking as risk factors in patients with acute myocardial infarction (AMI) and changes in the former levels with vitamins supplementation. Study Design: An interventional study. Place and Duration of Study: Medical College for Women and Hospital (MCW and H), Dhaka, Bangladesh, from July 2008 to December 2009. Methodology: Consecutive AMI patients were recruited from the Coronary Care Unit (CCU) at MCW and H, Dhaka. Blood samples were collected at inclusion (Patient-I0). They were given conventional treatments and prescribed vitamins (vitamins B6=25 mg, B12=2 mg and folic acid=2.5 mg) daily for 2 months. After follow-up, blood samples were taken again (Patient-II0). A group of 25 normal subjects were also included as controls. Serum tHcy and Lp(a) were measured by kinetic method and nephelometric method respectively. Results: Serum tHcy (macor mol/L) and Lp(a) (mg/dl) levels were elevated in Patient-I that reduced in Patient-II after vitamins supplementation, but not to the normal control level. tHcy of Patient-I0 was 25.1 +- 4.7 macro mol/L, of Patient-II0 was 20.1 +- 4.5 mu mol/L and of controls 12.1 +- 3.3, p 0.1). However, in a significant proportion of patients tHcy and Lp(a) levels were reduced to control levels (tHcy: p < 0.001, Lp(a): p < 0.01). Conclusion: These results indicated that tHcy and Lp(a) levels were possibly atherogenic risk factors independent of conventional risk factors. Since both tHcy and Lp(a) levels responded in a similar fashion, a common point of the metabolic and pathogenetic pathways of tHcy and Lp(a) may be influenced by the vitamins supplementation.

    PAF-ase is a specific serum enzyme that inactivates PAF by hydrolyzing acetate from the sn-2 position of the glycerol backbone. A reproducible PAF-ase activity assay was developed. A unit is based on the amount of serum required to release 3.61 +/- 0.042 pm 3 H-acetate from 10 pm 3 H-labeled PAF after incubation for 1 hr at 37 0 C. Assays on two single reference serums repeated 7 days were 0.63 +/- 0.013 U and 1.33 +/- 0.031 U. Serum from 20 normal men and 20 normal premenopausal women had significantly different (p = <0.001) levels of 1.32 +/- 0.072 U and 0.97 +/- 0.051 U respectively. They previously reported that PAF-ase is associated with B-lipoprotein. Therefore, total cholesterol (TC), LDL and high density lipoproteins (HDL) were determined on these 40 serums. Regression analysis revealed PAF-ase units were correlated with LDL (r = 0.740; p = < 0.001) and, parenthetically, with the TC (r = 0.620; p = < 0.001) but not with HDL. These correlations were similar for men and women. Thus, serum PAF-ase was partially controlled by serum LDL levels and the higher PAF-ase levels in serum from men were due in part to higher (p = < 0.01) LDL levels in men (147.6 +/- 6.9 mg/dl) as contrasted to women (119.0 +/- 7.6 mg/dl). PAF is a potent inflammatory, bronchoconstrictive and hypotensive agent. These data indicate that sex and serum LDL levels of subjects must be considered during future studies of the role of PAF vs PAF-ase in different disease states

    Full Text Available Abstract Background Several common genetic polymorphisms in the low density lipoprotein receptor (LDL-R gene have associated with modifications of serum total cholesterol (TC and low density lipoprotein cholesterol (LDL-C levels, but the results are not consistent in different populations. Bai Ku Yao is a special subgroup of the Yao minority in China. The present study was undertaken to detect the association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 1024 subjects of Bai Ku Yao and 792 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples. Genotyping of the LDL-R gene Ava Ⅱ polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results The levels of serum TC, high density lipoprotein cholesterol (HDL-C, LDL-C, apolipoprotein (Apo A1 and the ratio of ApoA1 to ApoB were lower in Bai Ku Yao than in Han (P - and A+ alleles was 65.5% and 34.5% in Bai Ku Yao, and 80.7% and 19.3% in Han (P -A-, A-A+ and A+A+ genotypes was 42.6%, 45.9% and 11.5% in Bai Ku Yao, and 64.9%, 31.6% and 3.5% in Han (P P 3.20 mmol/L subgroups in Bai Ku Yao (P P P P +A+ genotype had higher serum LDL-C, TC, HDL-C or ApoA1 levels than the subjects with A-A+ and A-A- genotypes. Spearman rank correlation analysis revealed that the levels of LDL-C in Bai Ku Yao and HDL-C in Han were correlated with genotypes (P P Conclusions The association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels is different between the Bai Ku Yao and Han populations. The discrepancy might partly result from different LDL-R gene Ava Ⅱ polymorphism or LDL-R gene-enviromental interactions.

    Full Text Available Hypercholesterolemia is one of the risk factors of cardiovascular diseases. High blood cholesterol affects the general health and increases the mortality rate of cardiovascular diseases. High levels of cholesterol in the diet increases LDL levels and decreases the activity of LDL receptors in the liver. Oxidation of vascular LDL lipoproteins increases the development of atherosclerosis. Previous studies have indicated that consumption of antioxidants decreases hypercholesterolemia. This study evaluates the effect of vitamin E supplementation on blood lipid levels in high cholesterol-fed rats. In this experimental study, three groups of male rats (n=10 for each group were used. The control group received basic diet and one of the other two groups received a diet containing one percent cholesterol and while the other received the same diet plus vitamin E supplement (2500 IU/kg in dry matter of the diet for one month. After determining the values of TC, LDL, VLDL, HDL and TG the results indicated that in rats fed with 1% cholesterol apart from HDL and VLDL the other lipids had increased significantly compared with the control group (p

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

    Postpartum depression (PPD) is a psychiatric complication of childbirth affecting 10–20% of new mothers and has negative impact on both mother and infant. Serum lipid levels have been related to depressive disorders, but very limited literatures are available regarding the lipid levels in women with postpartum depression. The present study is aimed to examine the association of serum lipids with the development of postpartum depressive symptoms. This is a cross sectional study conducted at a tertiary care hospital in South India. Women who came for postpartum check-up at 6th week post-delivery were screened for PPD (September 2014-October 2015). Women with depressive symptoms were assessed using EPDS (Edinburgh Postnatal Depression Scale). The study involved 186 cases and 250 controls matched for age and BMI. Serum levels of lipid parameters were estimated through spectrophotometry and the atherogenic indices were calculated in all the subjects. Low serum levels of Total Cholesterol (TC) and High Density Lipoprotein cholesterol (HDL-c) were significantly low in PPD women with severe depressive symptoms. The study recorded a significant negative correlation between HDL-c and the EPDS score in PPD women (r = -0.140, p = 0.05). Interestingly, the study also observed a significant negative correlation between Body Mass Index (BMI) and EPDS scores in case group (r = -0.146, p = 0.047), whereas a positive correlation between the same in controls (r = 0.187, p = 0.004). Our study demonstrated that low levels of serum HDL-c is correlated with the development of severe depressive symptoms in postpartum women. Study highlights the role of lipids in the development of postpartum depressive symptoms. PMID:29444162

    The effects of exposure to ozone (O/sub 3/) on concentrations of serum lipids and lipoproteins were investigated. Male and female guinea pigs were exposed to O/sub 3/ at 1 ppm for two weeks. Serum concentrations of cholesterol, triglycerides, low density (LDL) and very low density (VLDL) lipoproteins were elevated after O/sub 3/ exposure, particularly in males. During O/sub 3/ exposure the food intake per day decreased (for a constant body weight), suggesting that metabolic rate and possibly basal metabolic rate was lower. Lung wet weights increased during O/sub 3/ exposure by 87% for males and 45% for females. When individual lung weight/body weight ratios were correlated with cholesterol and LDL values from the same animal, a high correlation is found for males (r . 0.81, P less than 0.05), suggesting that there may be a relationship between lipoprotein elevations and lung damage for males. Because elevated concentrations of lipids and lipoproteins in humans increase the risk of coronary heart disease (CHD), the lipoprotein results suggest that an epidemiological study of the incidence of CHD with metropolitan O/sub 3/ levels may be warranted.

    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)

    Ghrelin is known to play a role in glucose metabolism and in beta-cell function. There are controversies regarding the role of ghrelin polymorphisms in diabetes and diabetes-related phenotypes. The objective of this study was to examine polymorphisms of the ghrelin gene in a Korean cohort and investigate associations between them and susceptibility to type 2 diabetes and its related phenotypes. The ghrelin gene was sequenced to identify polymorphisms in 24 DNA samples. Common variants were then genotyped in 760 type 2 diabetic patients and 641 nondiabetic subjects. Genetic associations with diabetes-related phenotypes were also analyzed. Nine polymorphisms were identified, and four common polymorphisms [g.-1500C>G, g.-1062G > C, g.-994C > T, g.+408C > A (Leu72Met)] were genotyped in a larger study. The genotype distributions of these four common polymorphisms in type 2 diabetes patients were similar to those of normal nondiabetic controls. However, these four common polymorphisms were variably associated with several diabetes-related phenotypes, such as high-density lipoprotein (HDL) cholesterol, fasting plasma glucose, and homeostasis model assessment of insulin resistance. In particular, subjects harboring g.-1062C were associated with a lower serum HDL cholesterol level after adjusting for other variables (P = 0.0004 or 0.01 after Bonferroni correction for 24 tests). The aforementioned four common polymorphisms in the ghrelin gene were not found to be significantly associated with susceptibility to type 2 diabetes mellitus in the Korean population. However, the common polymorphism g.-1062G > C in the promoter region of the ghrelin gene was found to be significantly associated with serum HDL cholesterol levels.

    Oral cancer is the 8th most common cancer worldwide. Squamous cell carcinomas constitute 94% of all oral malignancies and are often preceded by leukoplakia. Despite many adjunctive techniques to monitor transformation of leukoplakia to oral squamous cell carcinoma (OSCC), the mortality rate is on the rise. Incidentally, patients diagnosed with oral potentially malignant disorders (OPMDs) and oral cancers manifest with low choles-terol levels. Given a thought, hypolipidemia may be a useful adjunctive tool as it reflects the initial changes within the neo-plastic cells, thus giving a red alert in malignant transformation of leukoplakia at the earlier stage. To evaluate the feasibility of serum lipid profile as an adjunct early marker for malignant transformation of leukoplakia to OSCC. To estimate the serum cholesterol, triglycerides and lipoprotein (HDL, LDL, VLDL) levels in patients with leukoplakia, OSCC and age matched healthy control group. To compare the serum cholesterol, triglycerides and lipoprotein levels between patients of leukoplakia, OSCC and age matched healthy control group. The study group comprised of selected 30 individuals which included 10 each of histopathologically confirmed OSCC, leukoplakia and healthy controls. A written consent was taken from all of them, and a thorough case history was recorded and then venous blood was collected 12 hours post fasting and centrifuged. The serum cholesterol, triglycerides and HDL were estimated by enzymatic and colorimetric methods using commercially available kits--Roche/ Hitachi cobas systems. Chemistry assay QC procured from Bio-Rad was used as control. VLDL and LDL were derived from these values. Results were statistically analyzed using ANOVA and post hoc Tukey Test. Oral squamous cell carcinoma patients demonstrated significantly lower mean serum cholesterol level (151.60 mg/dl) than the control group (183.70 mg/dl). The mean cholesterol level in leukoplakia patients (173.90 mg/dl) was lower than that

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

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

    Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

    Human sera were incubated with rat liver lipase after inactivation of lecithin:cholesterol acyltransferase, and the changes in serum lipoprotein composition were measured. In the presence of liver lipase serum triacylglycerol and phosphatidylcholine were hydrolyzed. The main changes in the concentrations of these lipids were found in the high-density lipoprotein fraction. Subfractionation of high-density lipoprotein by rate-zonal ultracentrifugation showed a prominent decrease in all constituents of high-density lipoprotein2, a smaller decrease in the 'light' high-density lipoprotein3 and an increase in the 'heavy' high-density lipoprotein3. These data support a concept in which liver lipase is involved in high-density lipoprotein2 phospholipid and triacylglycerol catabolism and suggest that as a result of this action high-density lipoprotein2 is converted into high-density lipoprotein3.

    Full Text Available Abstract Background Chlamydia trachomatis was previously shown to express a lipoprotein, the macrophage infectivity potentiator (Mip, exposed at the bacterial surface, and able to stimulate human primary monocytes/macrophages through Toll Like Receptor (TLR2/TLR1/TLR6, and CD14. In PMA-differentiated THP-1 cells the proinflammatory activity of Mip was significantly higher in the absence than in the presence of serum. The present study aims to investigate the ability of different serum factors to attenuate Mip proinflammatory activity in PMA-differentiated THP-1 cells and in primary human differentiated macrophages. The study was also extend to another lipoprotein, the Borrelia burgdorferi outer surface protein (OspA. The proinflammatory activity was studied through Tumor Necrosis Factor alpha (TNF-α and Interleukin (IL-8 release. Finally, TLR1/2 human embryonic kidney-293 (HEK-293 transfected cells were used to test the ability of the serum factors to inhibit Mip and OspA proinflammatory activity. Results In the absence of any serum and in the presence of 10% delipidated FBS, production of Mip-induced TNF-α and IL-8 in PMA-differentiated THP-1 cells were similar whereas they were significantly decreased in the presence of 10% FBS suggesting an inhibiting role of lipids present in FBS. In the presence of 10% human serum, the concentrations of TNF-α and IL-8 were 2 to 5 times lower than in the presence of 10% FBS suggesting the presence of more potent inhibitor(s in human serum than in FBS. Similar results were obtained in primary human differentiated macrophages. Different lipid components of human serum were then tested (total lipoproteins, HDL, LDL, VLDL, triglyceride emulsion, apolipoprotein (apoA-I, B, E2, and E3. The most efficient inhibitors were LDL, VLDL, and apoB that reduced the mean concentration of TNF-α release in Mip-induced macrophages to 24, 20, and 2%, respectively (p Conclusions These results demonstrated the ability of

    The great significance for the metabolism of lipoproteins is the composition of carbohydrate chain of apolipoproteins, where sialic acid (SA) is located. In VILDL and LDL sialic acid is attached to apolipoprotein B. The sialylation of serum proteins including apolipoprotein B can be affected in the course of liver diseases. Therefore, the aim of this study was to assess the effect of liver diseases on the concentration and content of SA in ApoB-containing lipoproteins. The tested group consisted of 165 patients (118 males, 47 females) with liver diseases: alcoholic cirrhosis, non-alcoholic cirrhosis, chronic hepatitis, toxic hepatitis, chronic viral hepatitis, and liver cancer. ApoB-containing lipoproteins were isolated by a turbidimetric procedure and SA concentration was measured according to an enzymatic method. There was a significant increase in the serum concentration of SA in ApoB-containing lipoproteins in viral hepatitis. Although the serum concentration of ApoB was not significantly different between specific liver diseases, the serum levels of SA in ApoB-containing lipoproteins appeared to be different. There is an association between SA concentration and triglycerides in alcoholic cirrhosis and viral hepatitis. Also, in viral hepatitis SA concentration correlated negatively with HDL-cholesterol. The content of SA in ApoB-containing lipoproteins in alcoholic cirrhosis and viral hepatitis was significantly higher than that in the control group, but did not differ between diseases. This study may explain the variations in serum lipids and lipoproteins in liver diseases. It seems that the reason for these abnormalities is the changes in the concentration of sialic acid in ApoB-containing lipoproteins.

    The urinary excretion of lipoproteins and the possibility of catabolic alterations on glomerular filtration were investigated in four nephrotic subjects difering in etiology, serum lipoprotein profile, and 24 hr urinary output of protein and lipids. The apolipoproteins and lipoproteins of urine were compared with those of serum with respect to distribution profile, physical properties, and composition. As expected from molecular sieving effects during glomerular filtration, the urinary HDL were more abundant than the lower density lipoproteins even when the plasma LDL was elevated markedly. Intact apolipoproteins were not found in the concentrated urinary fraction isolated by ultrafiltration between the limits of 10/sup 4/ and 5 x 10/sup 4/ daltons. On the basis of immunoreactivity, gel electrophoresis, and amino acid composition, apolipoproteins B and AI are the major and minor proteins, respectively, of urinary LDL, and apo B is the major protein of the urinary IDL and VLDL. Apolipoproteins AI, AII, CI, CIII, and possibly AIV were isolated from the urinary HDL. As much as 20% of the protein moiety of the urinary HDL appeared to be large apolipoprotien fragments with molecular weights and isoelectric points similar to those of apo CII and apo CIII. The lower density classes of urinary lipoproteins also appeared to have lost apo E and apo C's and to have undergone partial proteolysis.

    Full Text Available Objective. To investigate the association between serum lipoprotein ratios and insulin resistance in women with polycystic ovarian syndrome (PCOS. Methods. 105 PCOS patients and 109 controls were randomly enrolled in the study. Serum levels of luteinizing hormone (LH, follicle-stimulating hormone (FSH, estradiol (E2, total testosterone (T, fasting glucose (FBG, fasting insulin (FINS, serum triglycerides (TG, total cholesterol (TC, high-density lipoprotein (HDL-C, and low-density lipoprotein (LDL-C levels were checked, and then TG/HDL-C ratio, TC/HDL-C, ratio and LDL-C/HDL-C ratio were calculated. The homeostasis model assessment of insulin resistance (HOMA-IR was used to calculate the insulin resistance. Results. All lipoprotein ratios were significantly higher in PCOS patients as compared to healthy controls (<0.05. TG/HDL-C ratio, TC/HDL-C ratio, and LDL-C/HDL-C ratio were significantly correlated with HOMA-IR (<0.05. The ROC curve demonstrated that TC/HDL-C ratio had higher sensitivity and specificity in diagnosing PCOS with insulin resistance. Conclusion. This study demonstrates that serum lipoprotein ratio significantly correlates with insulin resistance and can be used as the marker of insulin resistance in PCOS patients.

    In murine models of obesity/diabetes, there is an increase in plasma serum amyloid A (SAA) levels along with redistribution of SAA from high-density lipoprotein (HDL) to apolipoprotein B (apoB)-containing lipoprotein particles, namely, low-density lipoprotein and very low-density lipoprotein. The goal of this study was to determine if obesity is associated with similar SAA lipoprotein redistribution in humans. Three groups of obese individuals were recruited from a weight loss clinic: healthy obese (n = 14), metabolic syndrome (MetS) obese (n = 8), and obese with type 2 diabetes (n = 6). Plasma was separated into lipoprotein fractions by fast protein liquid chromatography, and SAA was measured in lipid fractions using enzyme-linked immunosorbent assay and Western blotting. Only the obese diabetic group had SAA detectable in apoB-containing lipoproteins, and SAA reverted back to HDL with active weight loss. In human subjects, SAA is found in apoB-containing lipoprotein particles only in obese subjects with type 2 diabetes, but not in healthy obese or obese subjects with MetS.

    Lipoprotein-A (LpA) is an emerging independent risk factor for cerebro- and cardio-vascular diseases (CCVD). Recognizing its function and its normal distribution is of fundamental importance for a better understanding of CCVD patho-physiology. The present study evaluated plasma LpA levels of healthy university students using turbidimetric methods. Medians and inter-quartile differences obtained for male and female participants were 11.3mg/dL (3.1-30.7) and 20.9mg/dL (6.5-42.3), respectively, demonstrating a significant difference (P=0.017) between men and women. A third of students showed plasma concentrations above reference values. Our results indicate that 33% of students possess a hidden independent risk factor for CCVD. Multi-disciplinary evaluation and characterization of young individuals should be recommended in an attempt to take early preventive measures and to eliminate possible modifiable risk factors such as sedentary lifestyle, smoking, hypertension, obesity and atherogenic diet.

    Full Text Available Reduced low-density lipoprotein (LDL cholesterol level is a characteristic feature of dyslipidemia in chronic hepatitis C virus (HCV infection. However, abnormality in serum triglyceride (TG has not been fully investigated. To clarify the impact of HCV genotype 1b (G1b infection and advanced fibrosis on serum TG profiles, TG concentrations in lipoprotein fractions were examined in fasting sera from 185 subjects with active or cleared HCV infection by high-performance liquid chromatography. Serum lipoproteins were fractionated into four classes: chylomicron, very low-density lipoprotein (VLDL, LDL, and high-density lipoprotein (HDL. Then, the significance of HCV G1b infection on TG levels in each lipoprotein fraction was determined using multiple regression models. We found that active HCV G1b infection was positively associated with high HDL-TG levels and low VLDL-TG levels, independent of other factors included in the regression model. In VLDL sub-fractions, active HCV infection was only found to be associated with low levels of large VLDL-TG. Similarly, advanced liver fibrosis in chronic HCV G1b infection was associated with high levels of LDL-TG, HDL-TG, and small VLDL-TG, independent of other clinical factors. These findings indicate that active HCV G1b infection and advanced fibrosis are closely associated with abnormal serum TG profiles.

    Full Text Available Introduction: Breast feeding is protective for atherosclerotic cardiovascular disease, obesity, Diabetes Mellitus (DM and hypertension. Serum lipoprotein is principal risk factor for atherosclerosis. There is growing evidence that risk of Coronary Heart Disease (CHD begins to emerge from infancy. Lipoprotein level is affected by different feeding pattern during infancy. Aim: To compare serum lipoprotein profile of exclusively breast fed, mixed fed and formula fed preterm infant. Materials and Methods: A total of two fifty preterm newborn were recruited at birth and divided into three groups. Group A were Exclusively Breast Fed (EBF, Group B were Mixed Fed (MF and Group C were Formula/bovine milk Fed (FF infants. Preterm newborns with severe sepsis, hypoglycemia, Hypoxic Ischemic Encephalopathy (HIE stage II and III, meconium stained amniotic fluid, pathological jaundice, Hyaline Membrane Disease (HMD, less than 28 weeks gestation, with major congenital anomaly and infants born to mothers with DM, gestational diabetes, hypertension, pre-eclampsia, eclampsia or on long term medications were excluded from the study. Lipoprotein profile estimation was done at four weeks and again at 16 weeks of age. Results: At four weeks of age, Total Cholesterol (TC, Triglyceride (TG, Low Density Lipoprotein (LDL and Very Low Density Lipoprotein (VLDL were higher in EBF infants as compared to MF and FF infants. For TC, difference was significant between EBF vs. MF (p<0.001, EBF vs. FF (p<0.001 and MF vs. FF (p=0.005 infants. At 16 weeks also, TC and HDL were higher in EBF infants as compared to MF and FF infants. For TC, this difference was significant between EBF vs. MF (p<0.001 and EBF vs. FF (p<0.001 infants. When infants were followed up to 16 weeks of age, TC and LDL level fell significantly (p<0.001 in EBF and MF group, a significant (p<0.05 rise for TC was seen in FF group. At 16 weeks of age, there was no significant rise in HDL in EBF infants, but

    Full Text Available Background: It has been suggested that moderate shrimp consumption in normolipidemic subjects will not adversely affect the overall lipoprotein profile. Hence, shrimp consumption can be included in “healthy heart" nutritional guidelines. However, the effects of cultured shrimp on serum lipoproteins of normal subjects have not yet investigated. Material and Methods: Twenty-five healthy normolipidemic men who were workers of a shrimp farm in Bushehr province participated in a quasi-experimental study. In a crossover six weeks trial, the effect of three days per week diet (containing 300 g cultured shrimp Litopenaeus vannamei /day on serum lipid profile was compared with a zero-marine baseline diet. Results: After six weeks trial, serum triglyceride and HDL-cholesterol levels were not significantly changed from the baseline levels (p>0.05. However, total cholesterol and LDL-cholesterol levels, total cholesterol to HDL-cholesterol and LDL-cholesterol to HDL-cholesterol ratios were significantly increased (p<0.0001. Conclusion: Moderate cultured shrimp (Litopenaeus vannamei consumption can increase total cholesterol and LDL-cholesterol levels in normolipidemic men. Although a diet containing native shrimp has many benefits for healthy persons, but we do not recommend cultured shrimp in a healthy heart diet for persons with dyslipidemia or cardiovascular diseases.

    Full Text Available BACKGROUND: Soy milk (SM and its fermented products are identified as rich sources of bioactive compounds helping to manage and to reduce the risk of chronic disease. This study aimed to compare the effects of SM and probiotic SM (PSM consumption on serum low-density lipoprotein cholesterol (LDL-C and high-density lipoprotein cholesterol (HDL-C in diabetic Wistar rats. METHODS: Probiotic SM was prepared by fermentation of the plain SM with a native strain of Lactobacillus plantarum. 20 streptozotocin-nicotinamide-induced diabetic Wistar rats were divided into two groups based on the type of administered SM (SM group and PSM group. The animals were fed with 1 ml/day of either soy or PSM for 21 days. The serum lipoprotein levels were analyzed at baseline and the end of the intervention period. RESULTS: HDL-C increased significantly in PSM group. Furthermore, this group showed more percent of change in increased HDL-C in compression with SM group (P < 0.050. Regarding LDL-C level, rats fed with SM was not significantly different from the PSM group (P < 0.050; though, this biomarker was reduced in both group. CONCLUSION: Probiotic SM could modulate blood lipoprotein levels. Thus, it may be considered in managing diabetes complications and atherosclerotic risks.

    1. An experiment was conducted to study the comparative effects of peach palm oil (PPO, Bactris gasipaes H.B.K), crude palm oil (CPO, Elaeis guinenesis), maize oil (MO) and beef tallow (BT) on serum total and lipoprotein cholesterol levels and haemostatic factors in broiler chickens. 2. Four experimental diets were formulated to be isocaloric (14·2 MJ AME(N)/kg) and isonitrogenous (230 g CP/kg). PPO was extracted from the whole dry fruit with hexane. Each fat was added to the diet in an amount equivalent to 25% of total dietary calories. Six replicate groups of eight male broiler chicks were assigned randomly to each dietary treatment. Diets were fed on ad libitum basis. The experiment lasted 42 d. 3. At 42 d, birds were fasted overnight and three chickens/dietary treatment were utilised to draw blood for lipoprotein separation. Various haemostatic factors were determined in thrombocyte-poor plasma. Thrombocyte aggregation was assayed in whole blood. 4. No significant differences were detected in body-weight gain or feed efficiency between the chickens fed on the PPO diet and those receiving the CPO, MO or BT diets. Total serum cholesterol (TC), very low density lipoprotein cholesterol and low density lipoprotein cholesterol (LDL(C)) were not significantly affected after consuming the PPO, CPO and MO diets. Serum high density lipoprotein cholesterol (HDL(C)) was reduced only by the MO diet. Birds fed on the PPO diet had a significantly lower [corrected] LDLC/HDLC ratio compared with other dietary treatments 5. Thrombocyte count and thrombin time were not significantly affected by the experimental diets. Dietary oils significantly affected prothrombin time, fibrinogen concentration and thrombocyte aggregation. PPO and MO diets elicited the lowest fibrinogen levels compared to the CPO and BT diets. Thrombocyte aggregation in broilers fed on the PPO diet was similar to that of the CPO, MO and BT diets. 6. The results suggest that PPO might efficiently provide up to

    Dyslipidemia and insulin resistance (IR), occurring in most infertile women with polycystic ovarian syndrome (PCOS), increase the risk of cardiovascular disease (CVD) and type 2 diabetes. This study aimed to assess the relationships between lipoprotein ratios and IR in PCOS women. Thirty six infertile women with PCOS selected based on Androgen Excess Society (AES) criteria and 29 healthy women matched for age were recruited to this case-control study. After physical measurements, fasting serum glucose (Glu), insulin and lipid profile levels [triglycerides (TGs), total cholesterol (TC), low-density lipoproteincholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C)] were measured, while lipoprotein ratios (TC/HDL-C, LDL-C/HDL-C, TG/HDL-C) were calculated. IR was also calculated using homeostasis model assessment (HOMA)-IR. The optimal cutoffs of lipoprotein ratios in relation to HOMA-IR were calculated based on the Receiver Operating Characteristics (ROC) curve analysis using the area under curve (AUC). Waist circumference (WC), insulin levels, HOMA-IR, TG levels, and all lipoprotein ratios were significantly higher, while HDL-C was lower in PCOS group as compared to healthy controls. All lipoprotein ratios, TG levels, and WC are significantly correlated with insulin levels and HOMA-IR. Among lipoprotein ratios, the highest AUC of the ROC belonged to TG/HDL-C ratio with sensitivity of 63.6% and specificity of 84.4% (TG/HDL-C>3.19) as a marker of IR in infertile PCOS women. Lipoprotein ratios, particularly TG/HDL-C, are directly correlated with insulin levels and can be used as a marker of IR (HOMA-IR) in infertile PCOS patients.

  3. Acetaldehyde binding increases the catabolism of rat serum low-density lipoproteins

    International Nuclear Information System (INIS)

    Savolainen, M.J.; Baraona, E.; Lieber, C.S.

    1987-01-01

    Acetaldehyde was found to form adducts with rat serum lipoproteins. The binding of [ 14 C]acetaldehyde to lipoproteins was studied at low concentrations which are known to exist during ethanol oxidation. The amount of lipoprotein adducts was a linear function of acetaldehyde concentration up to 250 μM. Incubation of rat plasma low-density lipoproteins (LDL) with 200 μM acetaldehyde increased the disappearance rate of the 3 H-label from the cholesterol ester moiety of LDL injected into normal rats. The data show that even low concentrations of acetaldehyde are capable of affecting LDL metabolism. These findings may provide an explanation for the low concentrations of serum LDL in alcoholics. The alcohol-induced hyperlipidemia includes either a lack of increase or a decrease in the low-density lipoprotein (LDL) concentration, but the underlying mechanism is not known. It has been shown previously, that the acetylation of lysine residues of LDL apoprotein (apoB) by acetanhydride leads to rapid uptake of LDL particles by macrophages through a non-LDL receptor pathway. Since acetaldehyde, the first toxic metabolite of ethanol, is a chemically reactive compound capable of binding to proteins, they tested whether acetaldehyde forms adducts with serum lipoproteins and subsequently alters the catabolism of LDL. 19 references, 2 figures, 1 table

  6. Oxidized Lipoprotein as a Major Vessel Cell Proliferator in Oxidized Human Serum.

    Directory of Open Access Journals (Sweden)

    Yoshiro Saito

    Full Text Available Oxidative stress is correlated with the incidence of several diseases such as atherosclerosis and cancer, and oxidized biomolecules have been determined as biomarkers of oxidative stress; however, the detailed molecular relationship between generated oxidation products and the promotion of diseases has not been fully elucidated. In the present study, to clarify the role of serum oxidation products in vessel cell proliferation, which is related to the incidence of atherosclerosis and cancer, the major vessel cell proliferator in oxidized human serum was investigated. Oxidized human serum was prepared by free radical exposure, separated using gel chromatography, and then each fraction was added to several kinds of vessel cells including endothelial cells and smooth muscle cells. It was found that a high molecular weight fraction in oxidized human serum specifically induced vessel cell proliferation. Oxidized lipids were contained in this high molecular weight fraction, while cell proliferation activity was not observed in oxidized lipoprotein-deficient serum. Oxidized low-density lipoproteins induced vessel cell proliferation in a concentration-dependent manner. Taken together, these results indicate that oxidized lipoproteins containing lipid oxidation products function as a major vessel cell proliferator in oxidized human serum. These findings strongly indicate the relevance of determination of oxidized lipoproteins and lipid oxidation products in the diagnosis of vessel cell proliferation-related diseases such as atherosclerosis and cancer.

Age range of the subjects was 18–80 years. The TG levels in all the subjects were < 200 mg/dL; only one subject (1.89% had TC < 200 mg/dL; nine subjects (17.0% had HDL-C ≤ 35 mg/dL; for LDL-C only one subject (1.89% had a desirable level of < 130 mg/dL; for VLDL-C 29 subjects (54.7% had values 17.2 mg/dL and above. For therapeutic decision-making, TC/HDL-C and LDL-C/HDL-C, were calculated. In TC/HDL-C, three subjects (5.66% had values < 4.4 and in LDL-C/HDL-C, 41 subjects (77.4% had values < 4.5. Hence, TC, HDL-C, LDL-C, TC/HDL-C and slightly LDL-C/HDL-C and VLDL-C in the subjects could lead to increase coronary heart diseases. Results were matched for the age and sex of subjects.

    Oral mitotane (o,p'-DDD) is a cornerstone of medical treatment for adrenocortical carcinoma (ACC). Serum mitotane concentrations >14  mg/l are targeted for improved efficacy but not achieved in about half of patients. Here we aimed at a better understanding of intestinal absorption and lipoprotein association of mitotane and metabolites o,p'-dichlorodiphenylacetic acid (o,p'-DDA) and o,p'-dichlorodiphenyldichloroethane (o,p'-DDE). Lipoproteins were isolated by ultracentrifugation from the chyle of a 29-year-old patient and serum from additional 14 ACC patients treated with mitotane. HPLC was applied for quantification of mitotane and metabolites. We assessed NCI-H295 cell viability, cortisol production, and expression of endoplasmic reticulum (ER) stress marker genes to study the functional consequences of mitotane binding to lipoproteins. Chyle of the index patient contained 197  mg/ml mitotane, 53  mg/ml o,p'-DDA, and 51  mg/l o,p'-DDE. Of the total mitotane in serum, lipoprotein fractions contained 21.7±21.4% (VLDL), 1.9±0.8% (IDL), 8.9±5.5% (LDL1), 18.9±9.6% (LDL2), 10.1±4.0% (LDL3), and 26.3±13.0% (HDL2). Only 12.3±5.5% were in the lipoprotein-depleted fraction. Mitotane content of lipoproteins directly correlated with their triglyceride and cholesterol content. O,p'-DDE was similarly distributed, but 87.9±4.2% of o,p'-DDA found in the HDL2 and lipoprotein-depleted fractions. Binding of mitotane to human lipoproteins blunted its anti-proliferative and anti-hormonal effects on NCI-H295 cells and reduced ER stress marker gene expression. Mitotane absorption involves chylomicron binding. High concentrations of o,p'-DDA and o,p'-DDE in chyle suggest intestinal mitotane metabolism. In serum, the majority of mitotane is bound to lipoproteins. In vitro, lipoprotein binding inhibits activity of mitotane suggesting that lipoprotein-free mitotane is the therapeutically active fraction. © 2016 European Society of Endocrinology.

Results: The comparison of cholesterol rich diet with cholesterol + olive oil showed a higher mean of MDA in cholesterol rich group (P < 0.001. Biochemical factors and aortic lesion degree showed no significant difference between standard and olive oil group. Aortic lesions in cholesterol + olive oil showed nonsignificant lower degree than cholesterol group. Discussion: This findings showed preventive effect of olive oil against atherosclerosis which is independent of plasma lipoprotein effect, and suggested that probably olive oil acts on arteries directly.

    Because of an unfavorable serum lipoprotein profile, postmenopausal women are at risk of cardiovascular disease. Soy protein may help protect against these risk factors, although its effect on paraoxonase 1 (PON1) is not clear. The aim of the present study was to determine the effects of soy protein on serum concentration of lipoproteins and PON1 activity in hypercholesterolemic postmenopausal women. In a double-blind randomized clinical trial with a parallel design, 52 hypercholesterolemic postmenopausal women were randomly assigned to 50 g/day soy protein containing 164 mg isoflavones or placebo, for 10 weeks. Serum lipoproteins and PON1 activity were measured at baseline and at the 10th week. There was significant increase in PON1 activity (P=0.029) and a significant decrease in low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), LDL-C/high-density lipoprotein cholesterol (HDL-C), triacylglycerol/HDL-C and TC/HDL-C in the soy group compared with the placebo group (P=0.001, P=0.008, P=0.012, P=0.04 and P=0.029, respectively) at the end of the study. Similarly, PON1 activity was significantly increased (P=0.015) and LDL-C, TC, LDL-C/HDL-C, triacylglycerol/HDL-C and TC/HDL-C were significantly decreased (P=0.001, P=0.002, P=0.001, P=0.016 and P=0.001) at the end of the study compared with the beginning value in soy group. Soy protein reduces the cardiovascular disease risk in postmenopausal women because of both modest reductions in serum lipoproteins and an increase in PON1 activity.

    To investigate associations between blood low-density lipoprotein cholesterol (LDL-C) levels and the prevalence of acquired color vision impairment (ACVI) in middle-aged Japanese men. Participants in this cross-sectional study underwent color vision testing, ophthalmic examination, a standardized interview and examination of venous blood samples. Ishihara plates, a Lanthony 15-hue desaturated panel, and Standard pseudoisochromatic Plates part 2 were used to examine color vision ability. The Farnsworth-Munsell 100-hue test was performed to define ACVI. Smoking status and alcohol intake were recorded during the interview. We performed logistic regression analysis adjusted for age, LDL-C level, systemic hypertension, diabetes, cataract, glaucoma, overweight, smoking status, and alcohol intake. Adjusted odds ratios for four LDL-C levels were calculated. A total of 1042 men were enrolled, 872 participants were eligible for the study, and 31 subjects were diagnosed with ACVI. As compared to the lowest LDL-C category level (or=160 mg/dl). The multiple-adjusted ORs were 2.91 (95% CI, 0.87-9.70) for the 2nd highest category and 3.81 (95% CI, 1.03-14.05) for the highest level. Tests for trend were significant (Pmen with elevated LDL-C levels. These changes might be related to deteriorated neurologic function associated with lipid metabolite abnormalities.

    Full Text Available Introduction: Hyperlipidemia is a risk factor for atherosclerosis and cardiovascular diseases. Nuts such as almonds are high in unsaturated lipids and antioxidants. Some studies indicate that nuts have beneficial effects on cardiovascular system. Therefore, the aim of this study was evaluation of the effectiveness of shelled almonds on reduction of blood lipid and lipoprotein levels in hyperlipidemic patients. Methods: This study was a clinical trial (before and after and was done on 30 men volunteering for the study. They consumed 60 grams shelled almonds per day for four weeks. Their blood lipid, lipoprotein, apolipoprotein and lipoprotein (a levels were measured after and before almond consumption. Results: Shelled almond consumption caused significant decrease in serum cholesterol 36.1 mg/dl, triglyceride 45.94 mg/dl, LDL-cholesterol 28.68 mg/dl and increase in HDL-cholesterol 10.64 mg/dl(p<0.001. Shelled almond consumption decreased lipoprotein (a (2.11 mg/dl, apolipoprotein B100 (8.93 mg/dl and increased apolipoprotein A (1 1.74 mg/dl levels, but this effect was insignificant statistically. Conclusion: Continuous consumption of shelled almonds has beneficial effect on blood lipids and may play a preventive role in Atherosclerosis and coronary heart diseases. We therefore suggest that a daily intake of 60 grams of almonds can be used for treatment of hyprelipidemic patients.

    2009-01-01

    A method based on Asymmetric Flow Field-Flow Fractionation (AF4) was developed to separate different types of lipoproteins from human serum. The emphasis in the method optimization was on the possibilities to characterize the largest lipoprotein fractions (LDL and VLDL), which is usually not possible with the size-exclusion chromatography methods applied in routine analysis. Different channel geometries and flow programs were tested and compared. The use of a short fractionation channel was shown to give less sample dilution at the same fractionation power compared to a conventional, long channel. Different size selectivities were obtained with an exponential decay and a linear cross flow program. The ratio of the UV absorption signal to the light scattering signal was used to validate the relation between retention time and size of the fractionated particles. An experimental setup was developed for the simultaneous determination of the cholesterol and triglycerides distribution over the lipoprotein fractions, based on enzymatic reactions followed by UV detection at 500 nm. Coiled and knitted PTFE tubing reactors were compared. An improved peak sharpness and sensitivity were observed with the knitted tubing reactor. After optimization of the experimental conditions a satisfactory linearity and precision (2-3% rsd for cholesterol and 5-6% rsd for triglycerides) were obtained. Finally, serum samples, a pooled sample from healthy volunteers and samples of sepsis patients, were analyzed with the method developed. Lipoprotein fractionation and cholesterol and triglyceride distributions could be correlated with the clinical background of the samples.

    Chromium deficiency may cause insulin resistance, hyperinsulinemia, impaired glucose tolerance, and hyperlipidemia, recovered by chromium supplementation. The effect of chromium supplementation on serum lipids and glucose tolerance was tested in a double-blind 12-wk study of 23 healthy adult men aged 31 to 60 yr. Either 200 micrograms trivalent chromium in 5 ml water (Cr) or 5 ml plain water (W) was ingested daily 5 days each week. Half the subjects volunteered for glucose tolerance tests with insulin levels. At 12 wk high-density lipoprotein cholesterol increased in the Cr group from 35 to 39 mg/dl (p less than 0.05) but did not change in the water group (34 mg/dl). The largest increase in high-density lipoprotein cholesterol and decreases in insulin and glucose were found in those subjects having normal glucose levels together with elevated insulin levels at base-line. The data are thus consistent with the hypothesis that Cr supplementation raises high-density lipoprotein cholesterol and improves insulin sensitivity in those with evidence of insulin resistance but normal glucose tolerance.

    Early prediction of disease severity of acute pancreatitis (AP) would be helpful for triaging patients to the appropriate level of care and intervention. The aim of the study was to develop a model able to predict Severe Acute Pancreatitis (SAP). A total of 647 patients with AP were enrolled. The demographic data, hematocrit, High-Density Lipoprotein Cholesterol (HDL-C) determinant at time of admission, Blood Urea Nitrogen (BUN), and serum creatinine (Scr) determinant at time of admission and 24 hrs after hospitalization were collected and analyzed statistically. Multivariate logistic regression indicated that HDL-C at admission and BUN and Scr at 24 hours (hrs) were independently associated with SAP. A logistic regression function (LR model) was developed to predict SAP as follows: -2.25-0.06 HDL-C (mg/dl) at admission + 0.06 BUN (mg/dl) at 24 hours + 0.66 Scr (mg/dl) at 24 hours. The optimism-corrected c-index for LR model was 0.832 after bootstrap validation. The area under the receiver operating characteristic curve for LR model for the prediction of SAP was 0.84. The LR model consists of HDL-C at admission and BUN and Scr at 24 hours, representing an additional tool to stratify patients at risk of SAP.

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

Here we show that SAA induced macrophage foam cell formation. SAA-stimulated foam cell formation was mediated by c-jun N-terminal kinase (JNK) signaling. Moreover, both SAA and SAA-conjugated high density lipoprotein stimulated the expression of the important scavenger receptor lectin-like oxidized low-density lipoprotein receptor 1 (LOX1) via nuclear factor-κB (NF-κB). A LOX1 antagonist carrageenan significantly blocked SAA-induced foam cell formation, indicating that SAA promotes foam cell formation via LOX1 expression. Our findings therefore suggest that SAA stimulates foam cell formation via LOX1 induction, and thus likely contributes to atherogenesis

    To determine the interactive effects of hormones, exercise, and diet on plasma lipids and lipoproteins, serum estrogen and progesterone levels, nutrient intake, and plasma lipid, lipoprotein, and apolipoprotein concentrations were measured in 24 hypoestrogenic amenorrheic and 44 eumenorrheic female athletes. When compared to eumenorrheic athletes, amenorrheic athletes had higher levels of plasma cholesterol (5.47 +/- 0.17 vs. 4.84 +/- 0.12 mmol/L, P = 0.003), triglyceride (0.75 +/- 0.06 vs. 0.61 +/- 0.03 mmol/L, P = 0.046), low-density lipoprotein (LDL; 3.16 +/- 0.15 vs. 2.81 +/- 0.09 mmol/L, P = 0.037), high-density lipoprotein (HDL; 1.95 +/- 0.07 vs. 1.73 +/- 0.05 mmol/L, P = 0.007), and HDL2 (0.84 +/- 0.06 vs. 0.68 +/- 0.04 mmol/L, P = 0.02) cholesterol. Plasma LDL/HDL cholesterol ratios, very low-density lipoprotein and HDL3 cholesterol, and apolipoprotein A-I and A-II levels were similar in the two groups. Amenorrheic athletes consumed less fat than eumenorrheic subjects (52 +/- 5 vs. 75 +/- 3 g/day, P = 0.02), but similar amounts of calories, cholesterol, protein, carbohydrate, and ethanol. HDL cholesterol levels in amenorrheic subjects correlated positively with the percent of dietary calories from fat (r = 0.42, n = 23, P = 0.045) but negatively with the percent from protein (r = -0.49, n = 23, P = 0.017). Thus, exercise-induced amenorrhea may adversely affect cardiovascular risk by increasing plasma LDL and total cholesterol. However, cardioprotective elevations in plasma HDL and HDL2 cholesterol may neutralize the risk of cardiovascular disease in amenorrheic athletes.

    Full Text Available Elevated serum iron level is linked with an increased risk of diabetes and atherosclerosis. However, the pathological mechanism by which iron affects serum lipoprotein levels is unknown. To elucidate the mechanism, a high dose of ferrous ion was applied (final 60 µM, 120 µM to human serum lipoproteins, macrophages, and human dermal fibroblast (HDF cells. Iron-treated lipoproteins showed loss of antioxidant ability along with protein degradation and multimerization, especially co-treatment with fructose (final 10 mM. In the presence of fructose, HDF cells showed 3.5-fold more severe cellular senescence, as compared to the control, dependent on the dosage of fructose. In macrophages, phagocytosis of acetylated low-density lipoprotein (acLDL was more accelerated by ferrous ion, occurring at a rate that was up to 1.8-fold higher, than acLDL alone. After 24 weeks supplementation with 0.05% and 0.1% ferrous ion in the diet (wt/wt, serum total cholesterol (TC level was elevated 3.7- and 2.1-fold, respectively, under normal diet (ND. Serum triglyceride (TG was elevated 1.4- and 1.7-fold, respectively, under ND upon 0.05% and 0.1% ferrous ion supplementation. Serum glucose level was elevated 2.4- and 1.2-fold under ND and high cholesterol diet (HCD, respectively. However, body weight was decreased by the Fe2+ consumption. Iron consumption caused severe reduction of embryo laying and reproduction ability, especially in female zebrafish via impairment of follicular development. In conclusion, ferrous ion treatment caused more pro-atherogenic, and pro-senescence processes in human macrophages and dermal cells. High consumption of iron exacerbated hyperlipidemia and hyperglycemia as well as induced fatty liver changes and sterility along with reduction of female fertility.

One hundred and forty healthy men participated in this research. HDL was separated by sequential ultracentrifugation, and its fatty acid composition was analyzed by gas chromatography. PON1 activity was measured spectrophotometrically using paraxon as substrate. Results. Serum PON1 activity was directly correlated with the amount of stearic acid and dihomo-gamma-linolenic acid (DGLA. PON1/HDL-C was directly correlated with the amount of miristic acid, stearic acid, and DGLA and was inversely correlated with total amount of ω6 fatty acids of HDL. Conclusion. The fatty acid composition of HDL could affect the activity of its associated enzyme, PON1. As dietary fats are the major determinants of serum lipids and lipoprotein composition, consuming some special dietary fatty acids may improve the activity of PON1 and thereby have beneficial effects on health.

    Cardioprotective effect of high density lipoprotein (HDL) is, in part, dependent on its related enzyme, paraoxonase 1 (PON1). Fatty acid composition of HDL could affect its size and structure. On the other hand, PON1 activity is directly related to the structure of HDL. This study was designed to investigate the association between serum PON1 activity and fatty acid composition of HDL in healthy men. One hundred and forty healthy men participated in this research. HDL was separated by sequential ultracentrifugation, and its fatty acid composition was analyzed by gas chromatography. PON1 activity was measured spectrophotometrically using paraxon as substrate. Serum PON1 activity was directly correlated with the amount of stearic acid and dihomo-gamma-linolenic acid (DGLA). PON1/HDL-C was directly correlated with the amount of miristic acid, stearic acid, and DGLA and was inversely correlated with total amount of ω 6 fatty acids of HDL. The fatty acid composition of HDL could affect the activity of its associated enzyme, PON1. As dietary fats are the major determinants of serum lipids and lipoprotein composition, consuming some special dietary fatty acids may improve the activity of PON1 and thereby have beneficial effects on health.

    The expression and immunoreactivity of apolipoprotein (apo) A-I epitopes in high density lipoproteins (HDL) and serum has been investigated using two series of monoclonal antibodies (Mabs) which have been described elsewhere. Series 1 Mabs, identified as 3D4, 6B8, and 5G6, were obtained by immunization and screening with apoA-I, and series 2 Mabs, identified as 2F1, 4H1, 3G10, 4F7, and 5F6, were obtained by immunization and screening with HDL. These Mabs were characterized with respect to their binding to HDL particles in solution. In series 2 Mabs, 2F1, 3G10, and 4F7, which react with apoA-I CNBr-fragments 1 and 2, could precipitate 100% of 125 I-labeled HDL, while 4H1 and 5F6, which react with CNBr fragments 1 and 3, precipitated 90 and 60% of 125 I-labeled HDL, respectively. Therefore, three distinct epitopes mapped to CNBr fragments 1 and 2 have been identified which are expressed on all HDL particles, indicating that several antigenic do mains exist on apoA-I which have the same conformation on all apoA-I-containing lipoproteins. The Mabs reacting at these sites have significantly higher affinity constants for 125 I-labeled HDL than those that failed to precipitate 100% of HDL. This suggests that the high affinity Mabs react with apoA-I epitopes that are both expressed on all lipoproteins and located in thermo-dynamically stable regions of the molecules. All Mabs from series 1 precipitated 35% or less of 125 I-labeled HDL prepared from freshly collected serum, but the proportion of HDL particles expressing the epitopes for these Mabs doubled or more upon serum storage at 4 degrees C. The time course of the alteration of apoA-I antigen in vitro was measured in three normolipemic donors

    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.

    260 well trained male sportsmen between 17 and 30 years of age participating in a variety of events were examined for total serum cholesterol and lipoprotein cholesterol and compared with 37 moderately active leisure-time sportsmen and 20 sedentary controls of similar ages and sex. Lipoprotein cholesterol distribution was determined by quantitative electrophoresis. Mean HDL-cholesterol increased progressively from the mean of the sedentary control to the mean of the long-distance runners, indicating a graded effect of physical activity on HDL-cholesterol. In all sporting groups mean LDL-cholesterol tended to be lower than in the controls, no association between LDL-cholesterol and form of training being apparent. Except for the long-distance runners, all sporting groups tended to be lower in total cholesterol than the controls. The HDL-/total cholesterol and LDL/HDL ratios yielded a better discrimination between the physically active and inactive than the HDL-cholesterol alone. Significant positive correlations with maximal oxygen uptake and roentgenologically determined heart volume were found for HDL-cholesterol and HDL-/total cholesterol, and negative ones for LDL/HDL. Differences in the regressions among subsets made up of sporting groups under different physical demands suggest a positive relationship between lipoprotein distribution and the magnitude of the trained muscle mass.

    The hepatic and serum lipid concentrations in 49 dairy cows with displaced abomasum, 7 postpartum cows fasted for 6 days, and 14 healthy postpartum cows were studied. The cows with displaced abomasums were retrospectively allotted to 2 groups: those with greater than 15% liver fat (DAHF) and those with less than 15% liver fat (DALF). Liver total lipid concentrations were high in the DAHF group, exceeding these values in the fasted cows by 30% and in the healthy and DALF cows by 63% on the average. In contrast, the liver phospholipid concentrations were low in the DAHF group, intermediate in the fasted and DALF groups and high in the healthy group. On a group basis, an inverse relationship was observed between serum and liver lipid concentrations. The serum concentrations of both total and dextran-sulfate-precipitable (DSP) lipids were high in the fasted cows and were less in the DALF and healthy cows and in the DAHF cows (lowest). The between-group differences in serum total and serum DSP concentrations of triacylglycerol, cholesterol, and phospholipid followed the same quantitative pattern as the total lipids. However, the relative difference between groups was greater for each of the DSP lipid fractions. These results support the hypothesis that severe hepatic lipidosis in cattle occurs due to impaired hepatic lipoprotein synthesis and secretion.

    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)

    Full Text Available We recently reported that a water extract of laurel or turmeric,1,8-cineole enriched fractions, showed hypolipidemic activityin the zebrafish model. Therefore, the present study investigatedthe cineole’s anti-oxidant and anti-inflammatory activitiesin lipoprotein metabolism in vitro and in vivo. Cineolehad inhibitory effects on cupric ion-mediated oxidation of lipoproteinsin general, while simultaneously enhancing ferric ionremoval ability in high-density lipoprotein (HDL. Hypercholesterolemiawas induced in zebrafish using cholesterol-feedingtreatment, 4% cholesterol, for 3 weeks. After feeding with orwithout the addition of cineole, the results revealed that cineolepossessed lipid-lowering and anti-inflammatory activitiesin hypercholesterolemic zebrafish. In addition, serum amyloidA and interleukin-6 levels were lowered and lipid accumulationwas decreased in the liver. Conclusively, 1,8-cineole wasfound to have anti-oxidant activities in lipoprotein metabolismboth in vitro and in vivo with simultaneous reduction of lipidaccumulation in the liver of zebrafish.

    Full Text Available Background: The fatty acid (FA composition of serum lipids is related to the quality of dietary fat intake. Objective: To investigate the effects of a healthy Nordic diet (ND on the FA composition of serum cholesterol esters (CE-FA and assess the associations between changes in the serum CE-FA composition and blood lipoproteins during a controlled dietary intervention. Design: The NORDIET trial was a 6-week randomised, controlled, parallel-group dietary intervention study that included 86 adults (53±8 years with elevated low-density lipoprotein cholesterol (LDL-C. Serum CE-FA composition was measured using gas chromatography. Diet history interviews were conducted, and daily intake was assessed using checklists. Results: Food and nutrient intake data indicated that there was a reduction in the intake of fat from dairy and meat products and an increase in the consumption of fatty fish with the ND. The levels of saturated fatty acids in cholesterol esters (CE-SFA 14:0, 15:0, and 18:0, but not 16:0, showed a significant decrease after intake of ND compared to the control diet (p<0.01. Also, a significant increase in serum 22:6n – 3 was observed compared with the control diet (p<0.01. The changes in CE-SFA 14:0, 15:0, and 18:0 correlated positively with changes in LDL-C, HDL-C, LDL-C/HDL-C, ApoA1, and ApoB (p<0.01, respectively, whereas the changes in polyunsaturated fatty acids in cholesterol esters (CE-PUFA 22:6n – 3 were negatively correlated with changes in the corresponding serum lipids. Conclusions: The decreased intake of saturated fat and increased intake of n-3 PUFA in a healthy ND is partly reflected by changes in the serum CE-FA composition, which are associated with an improved serum lipoprotein pattern.

    An alpha slow-moving high-density-lipoprotein (HDL) subfraction was seen in a patient presenting with radiation enteritis and peritoneal carcinosis, who was given long-term cyclic parenteral nutrition. This subfraction, observed in addition to normal HDL, was precipitated with low-density lipoproteins (LDL) and very-low-density lipoproteins (VLDL) by sodium phosphotungstate-magnesium chloride. The patient's serum lipoproteins were analyzed after fractionation by density gradient ultracentrifugation. The alpha slow-moving HDL floated in the ultracentrifugation subfractions with densities ranging from 1.028 to 1.084 kg/L, and their main apolipoproteins included apolipoprotein E in addition to apolipoprotein A-I. These HDL were larger than HDL2. The pathogenesis of this unusual HDL subfraction is hypothesized

    Full Text Available Abstract Background Beta-thalassaemia major (b-TM has been defined as a combination of chronic hemolytic anemia, iron storage disease and myocarditis, and it has been associated with premature death especially due to heart failure. To the best of our knowledge the status of blood lipids in these patients has rarely been investigated. Thus, we assessed the levels of lipids and lipoproteins in a sample of cardiovascular disease free adult men and women with b-TM. Methods During 2003 we enrolled 192 consecutive patients with b-TM that visited our Institution for routine examinations. The Institution is considered the major reference center for b-TM in Greece. Of the 192 patients, 88 were men (25 ± 6 years old and 104 women (26 ± 6 years old. Fasting blood lipid levels were measured in all participants. Results Data analysis revealed that 4% of men and 2% of women had total serum cholesterol levels > 200 mg/dl, and 11% of men and 17% of women had triglyceride levels > 150 mg/dl. In addition, mean HDL cholesterol levels were 32 ± 11 mg/dl in men and 38 ± 10 mg/dl in women, lipoprotein-a levels were 8.3 ± 9 mg/dl in men and 8.8 ± 9 mg/dl in women, apolipoprotein-A1 levels were 111 ± 17 mg/dl in men and 123 ± 29 mg/dl in women, and apolipoprotein-B levels were 60 ± 20 mg/dl in men and 59 ± 14 mg/dl in women. Total-to-HDL cholesterol ratios were 3.7 ± 1.2 and 3.8 ± 1.5 in men and women, respectively. Conclusions The majority of the patients had blood lipid levels (by the exception of HDL-cholesterol within the normal range, and consequently the prevalence of lipid and lipoprotein abnormalities was much lower as compared to the general population of the same age. Interestingly, is that the total – to HDL cholesterol ratio was high in our patients, and may underline the importance of this index for the prognosis of future cardiac events in these patients.

    The complex changes in serum LH and FSH levels from infancy to adulthood are diversely evaluated by radioimmunoassays or bioassays. The relative lack of sensitivity and specificity of radioimmunoassay, using polyclonal antibodies, could possibly be overcome by new immunoradiometric assays, using specific antibodies to LH and FSH. Significant differences were indeed observed between radioimmunoassays and immunoradiometric assays. During the prepubertal period, LH levels, measured by the immunoradiometric assays, were below the sensitivity of the method in the majority of the samples. LH levels were, however, well detectable when measured with radioimmunoassay, showing the heterogeneity of circulating LH structures. At the onset of puberty, LH levels increased at least 3 to 4 times in both sexes, when measured with immunoradiometric assays, whereas their increase was only 20 to 60% with the radioimmunoassays. FSH levels remained well detectable in the prepubertal period whether measured by immunoradiometric or radioimmunoassays. At pubertal onset, FSH increase in both sexes was more important in the immunoradiometric assays. The results obtained with immunoradiometric assays give a better insight into the quantitative and qualitative function of the gonadotropes during childhood. The almost complete absence of LH during the prepubertal period and the steep increase at the onset of puberty better reflects the reported data obtained with bioassays. The persistance of significant levels of FSH in the prepubertal ages, and the lesser increase at the onset of puberty, when compared with LH, illustrates that the individual regulation of LH and FSH secretion vary over time and is influenced by developmental factors.

    The egg is a nutrient-dense food and contains antioxidative carotenoids, lutein and zeaxanthin, but its impact on serum cholesterol levels has been a matter of concern, especially for individuals who have high serum cholesterol levels. We conducted this study to determine whether and how the daily additional consumption of one egg affects serum lipid profiles and parameters of LDL oxidation in moderately hypercholesterolemic males. Nineteen male Japanese adults (total cholesterol [TC]>5.2mmol/L) participated, consuming one soft boiled egg per day for 4weeks in addition to their habitual diet. Despite the significant increase in their intake of dietary cholesterol during the intervention period, the subjects' serum concentrations of TC and low-density lipoprotein cholesterol (LDL-C) did not increase. Their serum malondialdehyde modified low-density lipoprotein (MDA-LDL) concentrations were significantly decreased and their LDL oxidation lag times, reflecting the resistance of free-radical-induced LDL lipid peroxidation (ex vivo), was prolonged after 2 and 4weeks. At weeks 2 and 4, the subjects' serum lutein+zeaxanthin concentrations were significantly higher than their baseline values and showed both an inverse relation with MDA-LDL and a positive relationship with the LDL oxidation lag time. These data showed that in moderately hypercholesterolemic males, the additional consumption of one egg per day for 4weeks did not have adverse effects on serum TC or LDL-C, and it might reduce the susceptibility of LDL to oxidation through an increase in the serum lutein and zeaxanthin concentrations.

    2001-01-01

    The changes in total serum cholestrol, serum triglyceride, HDL-cholesterol and LDL-cholesterol after twenty eight (28) days of consumption of moderate quantity of a commercial coffee preparation (NESCAFE brand) were studied in 30 human subjects consisting of 20 male and 10 female healthy adults. Significant increases in the mean total serum cholesterol concentration (110.8-126.5 mg/100 mls) and LDL- cholesterol concentration (78.4-94.5 mg/100 ml) were observed in the subjects. No significant differences were obtained in the mean HDL cholesterol concentration and in the mean serum triglyceride levels. The differences observed in the mean total serum cholesterol, LDL cholesterol, HDL- cholesterol and triglyceride concentrations in the individual male and female groups studied were not statistically significant. The results from this study suggest that short-term consumption of coffee may increase the total serum cholesterol and LDL cholesterol levels. It is therefore possible that long-term consumption of coffee may lead to clinically significant alterations in serum lipid profile and could be important in the aetiology of atherosclerotic vascular diseases such as coronary heart disease.

  13. Serum lipid levels in pregnancies complicated by preeclampsia

    Directory of Open Access Journals (Sweden)

    Valmir Jose de Lima

    Full Text Available CONTEXT AND OBJECTIVE: Pre-eclampsia is a disorder that occurs only during pregnancy. Postpartum changes relating to lipid metabolism may contribute towards the endothelial lesions observed in preeclampsia. Thus, the aim of the present study was to evaluate the lipid profile among patients who present preeclampsia and correlate these parameters with 24-hour proteinuria. DESIGN AND SETTING: Cross-sectional analytical study including 77 pregnant patients seen at Hospital Dório Silva. METHODS: This study involved 42 women with preeclampsia and 35 healthy pregnant women in the third trimester of pregnancy as controls. Blood samples were obtained from all the patients, and the serum levels of triglycerides, total cholesterol, low-density lipoproteins (LDL, high-density lipoproteins (HDL and very low density lipoproteins (VLDL were determined. Cases and controls were matched for maternal age, gestational week and body mass index. RESULTS: The VLDL and triglyceride values from the women with preeclampsia were significantly higher than those of the healthy women. There was a positive correlation between increased proteinuria and higher VLDL and triglyceride levels in patients with preeclampsia. CONCLUSION: Among the patients with preeclampsia, higher VLDL and triglyceride levels were positively correlated with proteinuria. These observations indicate that the pregnant women who presented elevated lipid levels were more susceptible to cardiovascular disorders and, consequently, pre-eclampsia.

    BACKGROUND Genomic analyses have suggested that the LPA gene and its associated plasma biomarker, lipoprotein(a) (Lp[a]), represent a causal risk factor for coronary heart disease (CHD). As such, lowering Lp(a) has emerged as a therapeutic strategy. Beyond target identification, human genetics may contribute to the development of new therapies by defining the full spectrum of beneficial and adverse consequences and by developing a dose-response curve of target perturbation. OBJECTIVES We attempted to establish the full phenotypic impact of LPA gene variation and to estimate a dose-response curve between genetically altered plasma Lp(a) and risk for CHD. METHODS We leveraged genetic variants at the LPA gene from 3 data sources: individual-level data from 112,338 participants in the UK Biobank; summary association results from large-scale genome-wide association studies; and LPA gene sequencing results from cases with and controls free of CHD. RESULTS One standard deviation genetically lowered Lp(a) level was associated with 29% lower risk of CHD (odds ratio [OR]: 0.71; 95% confidence interval [CI]: 0.69 to 0.73), 31% lower risk of peripheral vascular disease (OR: 0.69; 95% CI: 0.59 to 0.80), 13% lower risk of stroke (OR: 0.87; 95% CI: 0.79 to 0.96), 17% lower risk of heart failure (OR: 0.83; 95% CI: 0.73 to 0.94), and 37% lower risk of aortic stenosis (OR: 0.63; 95% CI: 0.47 to 0.83). We observed no association with 31 other disorders including type 2 diabetes and cancer. Variants that led to gain of LPA gene function increased risk for CHD whereas those that led to loss of gene function reduced CHD risk. CONCLUSIONS Beyond CHD, genetically lowered Lp(a) is associated with a lower risk of peripheral vascular disease, stroke, heart failure, and aortic stenosis. As such, pharmacological lowering of plasma Lp(a) may impact a range of atherosclerosis-related diseases. PMID:28007139

    Objective:To investigate the relation between serum amyloid A-low density lipoprotein (SAA-LDL) and genotoxicity in smokers. Study Design:An experimental study. Place and Duration of Study:Army Medical College, Rawalpindi and National Institute of Health (NIH), Islamabad, from June 2014 to February 2015. Methodology:Seventy healthy Sprague Dawley rats were purchased from NIH and exposed to cigarette smoke in smoke chamber for three months. Blood samples were drawn from each rat at the end of the study period. SAA-LDL was determined by enzyme-linked immunosorbent assay (ELISA). Genotoxicity was assessed by cytokinesis block micronucleus (CBMN) assay. Pearson correlation was used to find correlation between SAA-LDL and genotoxicity. Results:Strong positive correlation was found between SAA-LDL and micronuclei frequency in smoke-exposed rats (r=0.799, N=70, p <0.01). Conclusion:Statistically significant strong positive correlation between SAA-LDL and genotoxicity in smoke-exposed rats shows that changes in one is associated with changes in other and vice versa.

    Full Text Available Abstract Background Paraoxonase-1 (PON1 is an enzyme with numerous functions and receives an increasing interest in clinical and epidemiological studies. Sometimes samples are stored for longer periods at a certain temperature. Therefore the stability of PON1 activity must be checked and retained upon storage for longer periods. Results In this study the stability of PON1 activity has been tested in human serum samples during storage up to 12 months at 3 commonly used temperatures, -20°C, -70°C and −196°C. It was found that the stability of the PON1 activity is constant during 12 months of storage at −70°C and −196°C. Storage at −20°C resulted in a small but statistically significant decrease after 6 months to about 94% of its original value. Nonetheless, the rank order between the samples at T = 0 and 12 months remained the same. The same temperature dependence was found for the associated high-density lipoprotein. Conclusions It can be concluded that −70°C is the right temperature for storage to maintain the PON1 activity for at least one year. Storage at a lower temperature in liquid nitrogen (−196°C is not necessary.

    Full Text Available Egg is a major source of dietary cholesterol. The serum lipid response to egg shows marked individual variation, beingpartly genetically determined, and influence by ethnic groups and the overall diet response. In the present investigation, weinvestigated the effect of ingestion of egg and low density lipoprotein (LDL oxidation on serum lipid profile in hypercholesterolemicwomen. Forty hypercholesterolemic women volunteers on a cholesterol-lowering diet (CLD divided into 2 groups ina randomized controlled cross-over study of one egg per day (CLD + 1 egg for 4-week and three eggs per day (CLD + 3 eggsfor 4-week, separated by 4-week period egg-free. The body weight, blood pressure, serum lipid profiles and LDL oxidationwere measured at 4-week intervals. Cholesterol-lowering diet was applied throughout the study by a dietitian using a foodexchange program and 3-day dietary recall every 4 weeks. Compared to the values obtained at baseline, the mean serum totalcholesterol and LDL cholesterol of CLD + 3 eggs was not significantly different from baseline whereas of those of 4-week ofegg-free period and CLD + 1 egg were significantly decreased (238.3±2.9 mg/dL and 228.3±4.7 mg/dL compared to thebaseline (252.2±5.9 mg/dL as was LDL cholesterol (161.2±3.0 mg/dL and 155.7±4.8 mg/dL compared to the baseline (177.5±6.0 mg/dL (p<0.05. The study showed there were no significantly difference the body weight, blood pressure, HDL cholesterol,triglycerides or LDL oxidation during the study. However, serum total cholesterol and LDL cholesterol of 1 or 3 eggsper day after 4-week of egg consumption was not significantly higher than the egg-free period. The study suggests that inhypercholesterolemic women who are on cholesterol-lowering diet, consuming one or three eggs per day did not raise serumcholesterol or LDL cholesterol levels at 4 weeks or result in any change in LDL oxidation.

    Earlier studies in our group suggested that traditionally prepared buttermilk influences cholesterol metabolism. We therefore designed a study to evaluate whether traditionally prepared buttermilk lowers serum low-density lipoprotein cholesterol (LDL-C) and/or prevents the LDL-C raising effect of egg yolks. Mildly hypercholesterolemic subjects were randomly allocated to one of four diet groups consuming daily at lunch 80 ml skimmed milk with (n = 23) or without (n = 25) lutein-enriched egg yolk (28 g from 1.5 eggs providing 323 mg cholesterol) or traditionally prepared buttermilk with (n = 23) or without (n = 21) lutein-enriched egg yolk during a 12 week period. Fasting blood samples were taken to measure concentrations of serum lipids, (apo)lipoproteins, liver and kidney function markers, and plasma lutein, zeaxanthin and high-sensitive C-reactive protein (hsCRP). Egg yolk consumption significantly increased serum total cholesterol (total-C) (p = 0.035) and LDL-C concentrations (p = 0.022). Buttermilk did not change the effects of egg yolk on serum lipids and (apo)lipoproteins. There was a trend towards significant lower total-C (p = 0.077), but not LDL-C (p = 0.204) concentrations in the buttermilk groups. Plasma lutein and zeaxanthin concentrations increased significantly (p < 0.001) in the egg yolk groups. In mildly hypercholesterolemic subjects, daily consumption of traditionally prepared buttermilk for 12 weeks did not lower serum total-C or LDL-C concentrations, nor did it prevent the serum total-C and LDL-C raising effect of daily egg yolk consumption.

    Lipasin/Angptl8 is a feeding-induced hepatokine that regulates triglyceride (TAG) metabolism; its therapeutical potential, mechanism of action, and relation to the lipoprotein lipase (LPL), however, remain elusive. We generated five monoclonal lipasin antibodies, among which one lowered the serum TAG level when injected into mice, and the epitope was determined to be EIQVEE. Lipasin-deficient mice exhibited elevated postprandial activity of LPL in the heart and skeletal muscle, but not in white adipose tissue (WAT), suggesting that lipasin suppresses the activity of LPL specifically in cardiac and skeletal muscles. Consistently, mice injected with the effective antibody or with lipasin deficiency had increased postprandial cardiac LPL activity and lower TAG levels only in the fed state. These results suggest that lipasin acts, at least in part, in an endocrine manner. We propose the following model: feeding induces lipasin, activating the lipasin-Angptl3 pathway, which inhibits LPL in cardiac and skeletal muscles to direct circulating TAG to WAT for storage; conversely, fasting induces Angptl4, which inhibits LPL in WAT to direct circulating TAG to cardiac and skeletal muscles for oxidation. This model suggests a general mechanism by which TAG trafficking is coordinated by lipasin, Angptl3 and Angptl4 at different nutritional statuses.

    Dyslipidemia is a well-known risk factor for carotid stenosis progression, but triglycerides have attracted little attention. The aim of this study was to assess if serum triglycerides affect progression of carotid stenosis in patients with well-controlled low-density lipoprotein cholesterol (LDL-C) levels. This is a retrospective study in a single hospital consisting of 71 Japanese patients with internal carotid artery stenosis greater than or equal to 50% and normal serum LDL-C levels who underwent angiographic examination with or without the resultant carotid artery stenting or endarterectomy from 2007 to 2011, and were subsequently followed up for 4 years. Clinical factors including fasting serum triglyceride values were compared between the progression (≥10% increase in degree of carotid stenosis on ultrasonography) and the nonprogression groups. During 4 years, 15 patients (21.1%) had carotid stenosis progression on either side. Cox regression analysis demonstrated that symptomatic cases (hazard ratio [HR], 4.327; P = .019), coexisting intracranial arteriosclerotic stenosis (HR, 5.341; P = .005), and hypertriglyceridemia (HR, 6.228; P = .011) were associated with subsequent progression of carotid stenosis. Kaplan-Meier plots demonstrated that the progression-free survival rate was significantly higher in patients without hypertriglyceridemia and intracranial arteriosclerotic stenosis at baseline. Among patients with moderate to severe carotid stenosis and well-controlled LDL-C, hypertriglyceridemia was an important risk factor for progression of carotid stenosis irrespective of surgical treatments. It would be worthwhile to test if triglyceride-lowering medications suppress carotid stenosis progression. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    Full Text Available Lipoprotein(a is a plasma lipoprotein and known cardiovascular risk factor most recently implicated in the development of high-risk carotid atherosclerotic plaques without significant carotid stenosis. We present a case of a young African-American female with recurrent embolic strokes of undetermined source. After our thorough investigation we identified the link between a small, irregular plaque in the right internal carotid artery and an extremely elevated plasma level of lipoprotein(a as the source of her embolic strokes.

    Full Text Available Interleukin-6 (IL-6 is a pro-inflammatory cytokine that has been found to be increased in type 2 diabetic subjects. However, it still remains unclear if these elevated IL-6 levels are co-incidental or if this cytokine is causally related to the development of insulin resistance and type 2 diabetes in humans. Therefore, in the present study we examined insulin sensitivity, serum adipokine levels and lipid parameters in human subjects before and after treatment with the IL-6 receptor antibody Tocilizumab.11 non-diabetic patients with rheumatoid disease were included in the study. HOMA-IR was calculated and serum levels for leptin, adiponectin, triglycerides, LDL-cholesterol, HDL-cholesterol and lipoprotein (a (Lp (a were measured before as well as one and three months after Tocilizumab treatment. The HOMA index for insulin resistance decreased significantly. While leptin concentrations were not altered by inhibition of IL-6 signalling, adiponectin concentrations significantly increased. Thus the leptin to adiponectin ratio, a novel marker for insulin resistance, exhibited a significant decrease. Serum triglycerides, LDL-cholesterol and HDL-cholesterol tended to be increased whereas Lp (a levels significantly decreased.Inhibition of IL-6 signalling improves insulin sensitivity in humans with immunological disease suggesting that elevated IL-6 levels in type 2 diabetic subjects might be causally involved in the pathogenesis of insulin resistance. Furthermore, our data indicate that inhibition of IL-6 signalling decreases Lp (a serum levels, which might reduce the cardiovascular risk of human subjects.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate lipoprotein(a (Lp(a, total cholesterol, high density lipoprotein cholesterol (HDL, low density lipoprotein cholesterol (LDL, very low density lipoprotein cholesterol (VLDL , triglycerides , apolipoprotein A (apo A and B100 (apo B100, uric acid, glycaemic and insulin plasmatic concentrations in patients affected by acute stroke. In this group of patients, we have compared the variables between type 2 diabetic patients and non-diabetic patients. METHOD: We evaluate a total of 34 non-diabetic patients (22 males and 12 females; mean age 66.71 ± 10.83 years and a group of 26 type 2 diabetic patients (15 males and 11 females; mean age 66.35 ± 9.92 years in a cross-sectional study. RESULTS: Mean Lp(a concentration did not significantly differ between type 2 diabetic patients and non-diabetic subjects (29.49 ± 23.09 vs 44.81 ± 44.34 mg/dl. The distribution of Lp(alevels was highly skewed towards the higher levels in both groups, being over 30 mg/dl in 50%. Lp(a concentration was positively correlated with abdominal adiposity, using waist-hip ratio(WHR(p< 0.05. No association was found between Lp(a and others risk factors like sex, age, other lipidic parameters and the presence of stroke. CONCLUSIONS: Our results showed that there were no significant differences between diabetic and non-diabetic patients' serum Lp(a levels, which indicates that elevated Lp(a levels were associated with ischemic stroke, irrespective of the presence of type 2 diabetes mellitus (type 2 DM.

    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.

    Full Text Available Background/Aims: The contribution of emergent cardiovascular risk factors to atherosclerotic renal artery stenosis (ARAS is debated. We investigated the relationship of lipoprotein(a and prothrombotic factors with ARAS in hypertension. Methods: In 50 hypertensive patients with angiographic evidence of ARAS and 58 hypertensive patients who had comparable cardiovascular risk factor burden but no evidence of renovascular disease, we measured renal function, lipoprotein(a, homocysteine, and hemostatic-fibrinolytic markers. Results: Patients with ARAS were more frequently smokers and had longer duration of hypertension, heavier antihypertensive treatment, and worse renal function than controls. Lipoprotein(a was higher in patients with ARAS than controls, whereas no differences were found in homocysteine and all hemostatic variables. Multivariate analysis showed that lipoprotein(a was associated with ARAS independent of other confounders including renal function and history of coronary heart, cerebrovascular, and peripheral artery disease. Conclusion: Lipoprotein(a might contribute to the development of ARAS and detection of elevated levels of this lipoprotein could raise the suspicion of renovascular disease in patients with high blood pressure.

    Recent studies have shown that atherosclerosis is associated with erectile dysfunction and the serum bilirubin level. In this study, the serum total bilirubin levels of patients with erectile dysfunction were measured to investigate the relationship between the levels of erectile dysfunction and total bilirubin. A total of 94 patients with erectile dysfunction were divided into three groups; severe erectile dysfunction (33 patients), moderate erectile dysfunction (31 patients), and mild erectile dysfunction (30 patients). In addition, a control group was formed with 31 healthy men. The International Index of Erectile Function-5 Questionnaire was used to measure the quality of erection in all the groups. The body mass index was calculated for all the participants. The serum glucose, low-density lipoprotein and high-density lipoprotein, cholesterol, triglyceride, total bilirubin, and total testosterone levels were also determined. No statistically significant difference was observed between the groups in terms of the mean age, hypertension, smoking status, alcohol use, cardiovascular diseases, hepatobiliary disease, diabetes mellitus, and levels of total testosterone, low-density lipoprotein-cholesterol, and triglyceride. However, high-density lipoprotein, body mass index, and total bilirubin were significantly lower compared to the control group (p < 0.001). The serum total bilirubin level was found to be 0.41 ± 0.21 ng/dL in the severe erectile dysfunction, 0.43 ± 0.19 ng/dL in the moderate erectile dysfunction, and 0.48 ± 0.11 ng/dL in the mild erectile dysfunction groups (p < 0.001). Considering the significant differences between the erectile dysfunction and control groups in terms of serum total bilirubin levels, a low level of bilirubin may have a role in the etiology of erectile dysfunction.

    To clarify the alterations in serum adropin and preptin concentrations in preeclampsia, we determined serum adropin and preptin levels in 29 women with normal pregnancy and 32 women with preeclampsia. We found that maternal age, body mass index and fetal gender were not significantly different between two groups; however, blood pressure, gestational age and neonatal birth weight were significantly different. Serum adropin levels were significantly increased in women with preeclampsia compared with those with normal pregnancy but there were no significant differences in preptin levels. An increase in maternal serum adropin level was found in preeclampsia, and this may be a compensation for pregnancy complicated with preeclampsia.

    Full Text Available The efficacy of phytosterols and phytostanols added to foods and food supplements to obtain significant non-pharmacologic serum and low density lipoprotein (LDL cholesterol reduction is well documented. Irrespective of age, gender, ethnic background, body weight, background diet, or the cause of hypercholesterolemia and, even added to statin treatment, phytosterols and phytostanols at 2 g/day significantly lower LDL cholesterol concentration by 8%–10%. They do not affect the concentrations of high density lipoprotein cholesterol, lipoprotein (a or serum proprotein convertase subtilisin/kexin type 9. In some studies, phytosterols and phytostanols have modestly reduced serum triglyceride levels especially in subjects with slightly increased baseline concentrations. Phytosterols and phytostanols lower LDL cholesterol by displacing cholesterol from mixed micelles in the small intestine so that cholesterol absorption is partially inhibited. Cholesterol absorption and synthesis have been carefully evaluated during phytosterol and phytostanol supplementation. However, only a few lipoprotein kinetic studies have been performed, and they revealed that LDL apoprotein B-100 transport rate was reduced. LDL particle size was unchanged, but small dense LDL cholesterol concentration was reduced. In subjects with metabolic syndrome and moderate hypertriglyceridemia, phytostanols reduced not only non- high density lipoprotein (HDL cholesterol concentration but also serum triglycerides by 27%, and reduced the large and medium size very low density lipoprotein particle concentrations. In the few postprandial studies, the postprandial lipoproteins were reduced, but detailed studies with apoprotein B-48 are lacking. In conclusion, more kinetic studies are required to obtain a more complete understanding of the fasting and postprandial lipoprotein metabolism caused by phytosterols and phytostanols.

    1956-01-01

    A study was carried out to determine the effect of the level and type of dietary fat on the concentration of cholesterol and beta lipoproteins in the sera of Cebus monkeys. Three groups of monkeys were fed isocaloric diets containing a fixed ratio of alpha protein and cholesterol to calories but with different amounts of corn oil and sucrose. Corn oil provided 10, 32, and 45 per cent of the calories in the three diets, and the level of sucrose was varied inversely. After 8 weeks the serum cholesterol and Sf 12 to 100 beta lipoprotein concentrations were significantly greater in the medium and high fat groups. When corn oil was decreased from 45 to 10 per cent of dietary calories and sucrose was increased, the serum cholesterol fell in all cases, and when the reverse change was made, the concentration of serum cholesterol increased. Variation in dietary sucrose had no specific effect. Substitution of starch for sucrose with diets otherwise constant did not cause significant change in the concentration of serum cholesterol. When monkeys fed corn oil diets at any of three levels were changed to hydrogenated cottonseed oil diets at the same level, the serum cholesterol and Sf 12 to 100 beta lipoproteins rose. However, hydrogenated cottonseed oil had no greater hypercholesteremic effect than did corn oil in the absence of dietary cholesterol. Diets containing lard with cholesterol also produced strikingly greater serum lipide responses than did diets based on corn oil and cholesterol. Hydrogenated cottonseed oil had a greater hypercholesteremic effect than an unhydrogenated cottonseed oil from the same lot. Preliminary studies indicated that the saturated fats (hydrogenated cottonseed oil) produced the most striking elevation of serum cholesterol values (above controls fed corn oil) when casein was the dietary protein.

    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)

    Nikolova, K.; Vassileva, D.

    2003-01-01

    Erythropoietin (Epo) is the first well studied hemopoietic growth factor. The pathological levels of its serum concentration show deviations in the specific mechanisms for some diseases such as polycythemia. Objective of this work is the assessment of the diagnostic value of the Epo in the serum for the differentiation of the main form of polycythemia - true and symptomatic. Material and methods: 47 patients are studied (21 women and 26 men), 23 of them are with polycythemia vera and 24 with polycythemia symptomatica. The following has been determined: the serum level of Erythropoietin, hemoglobin, the number of erythrocytes, leukocytes, thrombocytes, myelogram. The serum level of Epo is quantitatively determined b using of radioimmunological method, through Epo-Trac kit. Results: The diagnosis is also confirmed in all patients by other laboratory tests. The normal values of Epo in healthy persons are 17.0±7.0 mU/ml. The average Epo level in patients with polycythemia vera is 20.4±3.0 mU/ml. In one patient the Epo level is supposedly connected with an accompanying kidney disease. Conclusions: The obtained data show that the Epo serum level is an accurate criterion in the diagnosing of true and symptomatic polycythemia. The true polycythemia is connected with an independent erythrocyte production. In the symptomatic polycythemia the tissue hypoxia stimulated the Epo production

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

    • BACKGROUND: The association between the lipid profiles level and the incidence and severity of coronary heart disease (CHD is very pronounced in epidemiological studies, and an inverse relation between physical fitness and the incidence of coronary heart disease has been observed in many studies. The aim of this study was to investigate the impact of a soccer match on lipid parameters of professional soccer players.
    • METHODS: Twenty two professional soccer players participated in the study. Blood (10ml for determination of lipid profiles was obtained at rest and immediately after a 90 minute soccer match. Lipid parameters were measured using Boehringer Mannheim kits and Clinilab and BioMerieux analyser.
    • RESULTS: The results of this study showed that the triglyceride was significantly higher before the match than afterwards (159.09 ± 58.2 vs. 88.63 ± 34.1 mg/dl, p < 0.001, whereas the low-density lipoprotein (LDL was lower before the match than after it (98.04 ± 28.9 vs. 112.31 ± 30.5 mg/dl. Moreover, there were no significant differences in cholesterol concentration (171.4 ± 30.28 mg/dl vs. 173.18 ± 32.75 mg/dl and high-density lipoprotein (HDL concentration (34.04 ± 5.58 mg/dl vs. 34.4 ± 4.6 mg/dl between before and after the match.
    • CONCLUSIONS: Although the soccer competitive match has no favourable acute effect on lipid

    • Examination of the relation between periodontal health status and cardiovascular risk factors: serum total and high density lipoprotein cholesterol, C-reactive protein, and plasma fibrinogen.

      Using data from the Third National Health and Nutrition Examination Survey (1988-1994), the authors examined the relation between periodontal health and cardiovascular risk factors: serum total and high density lipoprotein cholesterol, C-reactive protein, and plasma fibrinogen. A total of 10,146 participants were included in the analyses of cholesterol and C-reactive protein and 4,461 in the analyses of fibrinogen. Periodontal health indicators included the gingival bleeding index, calculus index, and periodontal disease status (defined by pocket depth and attachment loss). While cholesterol and fibrinogen were analyzed as continuous variables, C-reactive protein was dichotomized into two levels. The results show a significant relation between indicators of poor periodontal status and increased C-reactive protein and fibrinogen. The association between periodontal status and total cholesterol level is much weaker. No consistent association between periodontal status and high density lipoprotein cholesterol was detectable. Similar patterns of association were observed for participants aged 17-54 years and those 55 years and older. In conclusion, this study suggests that total cholesterol, C-reactive protein, and fibrinogen are possible intermediate factors that may link periodontal disease to elevated cardiovascular risk.

    • Increased concentration of clusterin/apolipoprotein J (apoJ) in hyperlipemic serum is paradoxically associated with decreased apoJ content in lipoproteins.

      Clusterin/apolipoprotein J (apoJ) circulates in blood in part associated to lipoproteins or in unbound form. When bound to HDL, apoJ is antiatherogenic by inhibiting endothelial cell apoptosis; thus, any factor modifying apoJ association to HDL would decrease its antiatherogenic function. However, the exact distribution of apoJ in each lipoprotein fraction, or in lipoprotein-non bound form has not been specifically investigated either in normolipemia or in dyslipemia. Basic lipid profile and apoJ concentration were determined in sera from 70 subjects, including a wide range of cholesterol and triglyceride concentrations. Lipoproteins were isolated by ultracentrifugation and their lipid and apolipoprotein composition was assessed. In the overall population, serum apoJ positively associated with cholesterol, triglyceride and VLDL-C concentrations, and HDL-C and triglyceride were independent predictors of increased apoJ concentration. Approximately, 20.5% of circulating apoJ was associated with lipoproteins (18.5% HDL, 0.9% LDL and 1.1% VLDL) and 79.5% was not bound to lipoproteins. Serum apoJ concentration was higher in hypercholesterolemic (HC), hypertriglyceridemic (HTG) and combined hyperlipidemic (CHL) sera compared to normolipemic (NL) sera (HC, 98.15 ± 33.6 mg/L; HTG, 103.3 ± 36.8 mg/L; CHL, 131.7 ± 26.8 mg/L; NL, 66.7 ± 33.8 mg/L; P lipoproteins in the NL group whereas this proportion rounded 15% in hyperlipidemic subjects. Our findings indicate that hyperlipidemia increases the concentration of apoJ in serum but, in turn, the content of lipoprotein-associated apoJ decreases. The redistribution of apoJ in hyperlipidemia could compromise the antiatherogenic properties of HDL. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    • Serum erythropoietin levels by radioimmunoassay in polycythaemia

      1982-01-01

      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.

      Full Text Available OBJECTIVE: To identify the association between food group consumption frequency and serum lipoprotein levels among adults. METHODS: The observations were made during a cross-sectional survey of a representative sample of men and women over 20 years old living in Cotia county, S. Paulo, Brazil. Data on food frequency consumption, serum lipids, and other covariates were available for 1,045 adults. Multivariate analyses adjusted by age, gender, body mass index, waist-to-hip ratio, educational level, family income, physical activity, smoking, and alcohol consumption were performed. RESULTS: Consumption of processed meat, chicken, red meat, eggs and dairy foods were each positively and significantly correlated with LDL-C, whereas the intake of vegetables and fruits showed an inverse correlation. Daily consumption of processed meat, chicken, red meat, eggs, and dairy foods were associated with 16.6 mg/dl, 14.5 mg/dl, 11.1 mg/dl, 5.8 mg/dl, and 4.6 mg/dl increase in blood LDL-C, respectively. Increases of daily consumption of fruit and vegetables were associated with 5.2 mg/dl and 5.5 mg/dl decreases in LDL-C, respectively. Alcohol beverage consumption showed a significant positive correlation with HDL-C. CONCLUSIONS: Dietary habits in the study population seem to contribute substantially to the variation in blood LDL and HDL concentrations. Substantially CHD risk reduction could be achieved with dietary changes.OBJETIVO: Identificar a associação entre a freqüência de consumo de diferentes grupos de alimentos e níveis de lipídios séricos de adultos.

      2013-01-01

      Full Text Available Background. Lipoprotein(a [Lp(a] is a known risk factor for cardiovascular disease, yet its influence on metabolic syndrome (MS is still controversial. The purpose of this study was to assess the impact generated by this diagnosis in serum Lp(a concentrations. Materials and Methods. A total of 1807 subjects of both genders (55.3% women and 44.7% men belonging to the Maracaibo City Metabolic Syndrome Prevalence Study were evaluated. Results were expressed as Mean ± SD, determining differences through Student’s t-test and One-Way ANOVA test. Multiple logistic regression models were utilized for analyzing factors associated with elevated serum Lp(a levels and MS. Total cholesterol and LDL-C were corrected according to Lp(a-Cholesterol when necessary. Results. No differences were found in Lp(a values between genders; P=0,292. The association between MS and the classification of Lp(a was statistically significant (χ2=28.33; P<0,0001, with greater levels in subjects with this diagnosis. In the univariate analysis, subjects with each of the separate diagnostic criteria showed higher serum Lp(a concentrations, except for hyperglycemia. Conclusions. Lp(a values exhibit important variations regarding MS and each of its components. Impaired fasting glucose appeared as a protecting factor against elevated Lp(a concentrations, whereas its association with LDL-C and hs-CRP suggests a potential pro-inflammatory role.

    • Serum prolactin level in patients taking olanzapine

      2015-01-01

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

      Murein lipoprotein (Lpp) and peptidoglycan-associated lipoprotein (Pal) are major outer membrane lipoproteins in Escherichia coli Their roles in cell-envelope integrity have been documented in E. coli laboratory strains, and while Lpp has been linked to serum resistance in vitro , the underlying mechanism has not been established. Here, lpp and pal mutants of uropathogenic E. coli strain CFT073 showed reduced survival in a mouse bacteremia model, but only the lpp mutant was sensitive to serum killing in vitro The peptidoglycan-bound Lpp form was specifically required for preventing complement-mediated bacterial lysis in vitro and complement-mediated clearance in vivo Compared to the wild-type strain, the lpp mutant had impaired K2 capsular polysaccharide production and was unable to respond to exposure to serum by elevating capsular polysaccharide amounts. These properties correlated with altered cellular distribution of KpsD, the predicted outer membrane translocon for "group 2" capsular polysaccharides. We identified a novel Lpp-dependent association between functional KpsD and peptidoglycan, highlighting important interplay between cell envelope components required for resistance to complement-mediated lysis in uropathogenic E. coli isolates. IMPORTANCE Uropathogenic E. coli (UPEC) isolates represent a significant cause of nosocomial urinary tract and bloodstream infections. Many UPEC isolates are resistant to serum killing. Here, we show that a major cell-envelope lipoprotein (murein lipoprotein) is required for serum resistance in vitro and for complement-mediated bacterial clearance in vivo This is mediated, in part, through a novel mechanism by which murein lipoprotein affects the proper assembly of a key component of the machinery involved in production of "group 2" capsules.

    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.

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

    Apolipoprotein A-I (apoA-I) mimetic peptides are currently being developed as possible new agents for the treatment of cardiovascular disease based on their ability to promote cholesterol efflux and their other beneficial antiatherogenic properties. Many of these peptides, however, have been reported to cause transient hypertriglyceridemia due to inhibition of lipolysis by lipoprotein lipase (LPL). We describe a novel bihelical amphipathic peptide (C-II-a) that contains an amphipathic helix (18A) for binding to lipoproteins and stimulating cholesterol efflux as well as a motif based on the last helix of apolipoprotein C-II (apoC-II) that activates lipolysis by LPL. The C-II-a peptide promoted cholesterol efflux from ATP-binding cassette transporter ABCA1-transfected BHK cells similar to apoA-I mimetic peptides. Furthermore, it was shown in vitro to be comparable to the full-length apoC-II protein in activating lipolysis by LPL. When added to serum from a patient with apoC-II deficiency, it restored normal levels of LPL-induced lipolysis and also enhanced lipolysis in serum from patients with type IV and V hypertriglyceridemia. Intravenous injection of C-II-a (30 mg/kg) in apolipoprotein E–knockout mice resulted in a significant reduction of plasma cholesterol and triglycerides of 38 ± 6% and 85 ± 7%, respectively, at 4 hours. When coinjected with the 5A peptide (60 mg/kg), the C-II-a (30 mg/kg) peptide was found to completely block the hypertriglyceridemic effect of the 5A peptide in C57Bl/6 mice. In summary, C-II-a is a novel peptide based on apoC-II, which promotes cholesterol efflux and lipolysis and may therefore be useful for the treatment of apoC-II deficiency and other forms of hypertriglyceridemia.

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

    Full Text Available In visceral leishmaniasis (VL endemic areas, a minority of infected individuals progress to disease since most of them develop protective immunity. Therefore, we investigated the risk markers of VL within nonimmune sector. Analyzing infected symptomatic and, asymptomatic, and noninfected individuals, VL patients presented with reduced high-density lipoprotein cholesterol (HDL-C, elevated triacylglycerol (TAG, and elevated very-low-density lipoprotein cholesterol (VLDL-C levels. A polymorphism analysis of the lipoprotein lipase (LPL gene using HindIII restriction digestion (N = 156 samples (H+ = the presence and H− = the absence of mutation revealed an increased adjusted odds ratio (OR of VL versus noninfected individuals when the H+/H+ was compared with the H−/H− genotype (OR = 21.3; 95% CI = 2.32–3335.3; P = 0.003. The H+/H+ genotype and the H+ allele were associated with elevated VLDL-C and TAG levels (P < 0.05 and reduced HDL-C levels (P < 0.05. An analysis of the L162V polymorphism in the peroxisome proliferator-activated receptor alpha (PPARα gene (n = 248 revealed an increased adjusted OR when the Leu/Val was compared with the Leu/Leu genotype (OR = 8.77; 95% CI = 1.41–78.70; P = 0.014. High TAG (P = 0.021 and VLDL-C (P = 0.023 levels were associated with susceptibility to VL, whereas low HDL (P = 0.006 levels with resistance to infection. The mutated LPL and the PPARα Leu/Val genotypes may be considered risk markers for the development of VL.

    Objective: To evaluate and compare the serum levels of visfatin, interleukin-6 and lipid profile in non-obese and obese male patients with coronary artery disease. Study Design: Observational, comparative study. Place and Duration of Study: Punjab Institute of Cardiology and Lahore General Hospital, Lahore, from July to December 2013. Methodology: The participants included 20 non-obese group I with coronary artery disease (CAD) and 20 obese males group II with coronary artery disease (angiographically confirmed). All the participants were in the age group of 35 - 55 years being non-smokers and non-diabetic. Serum visfatin and interleukin-6 levels were analysed by Enzyme Linked Immunosorbent Assay (ELISA). Lipid profile was also evaluated. Results were compared with T-test and Mann Whitney U test. The values were considered significant at 0.05 level of significance. Results: Serum visfatin 9.05 versus 3.9 ng/ml and interleukin-6 12.80 versus 0.60 pg/ml levels were significantly (p-value < 0.001 of both) raised in the obese CAD group as compared to non-obese with CAD. Lipid profile also showed raised levels of total serum cholesterol, low density lipoproteins, triglycerides, very low density lipoproteins and low levels of high density lipoproteins in obese group. Conclusion: Significantly raised levels of serum visfatin and interleukin-6 indicate adipose tissue as an imperative source of these adipocytokines involved in inflammation in CAD. Altered lipid profile also seen in obese patients with CAD. (author)

    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)

    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.

    Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further investigations.

    The aim of this study was to assess zinc levels in tinnitus patients, and to evaluate the effects of zinc deficiency on tinnitus and hearing loss. One-hundred patients, who presented to an outpatient clinic with tinnitus between June 2009 and 2014, were included in the study. Patients were divided into three groups according to age: Group I (patients between 18 and 30years of age); Group II (patients between 31 and 60years of age); and Group III (patients between 61 and 78years of age). Following a complete ear, nose and throat examination, serum zinc levels were measured and the severity of tinnitus was quantified using the Tinnitus Severity Index Questionnaire (TSIQ). Patients were subsequently asked to provide a subjective judgment regarding the loudness of their tinnitus. The hearing status of patients was evaluated by audiometry and high-frequency audiometry. An average hearing sensitivity was calculated as the mean value of hearing thresholds between 250 and 20,000Hz. Serum zinc levels between 70 and 120μg/dl were considered normal. The severity and loudness of tinnitus, and the hearing thresholds of the normal zinc level and zinc-deficient groups, were compared. Twelve of 100 (12%) patients exhibited low zinc levels. The mean age of the zinc-deficient group was 65.41±12.77years. Serum zinc levels were significantly lower in group III (p<0.01). The severity and loudness of tinnitus were greater in zinc-deficient patients (p=0.011 and p=0.015, respectively). Moreover, the mean thresholds of air conduction were significantly higher in zinc-deficient patients (p=0.000). We observed that zinc levels decrease as age increases. In addition, there was a significant correlation between zinc level and the severity and loudness of tinnitus. Zinc deficiency was also associated with impairments in hearing thresholds.

    This work undertakes, in a second part, the clinical exploration of 947 serum digoxin levels of 281 hospitalized patients on a cardiology ward. Our results, which coincide with those of other researchers, have led us to draw certain practical conclusions: the posology is determined first of all according to kidney function, weight and age of the patient. When the treatment is insufficient or, on the other hand, poorly tolerated, a serum digoxin level is performed permitting thus: in the case of ineffective treatment: to be sure of the patient's cooperation, to increase the posology if the serum digoxin level is not in the toxic zone, to discover an eventual pharmacokinetic problem; to establish the responsability of digitalis (when there are signs of intolerance or of intoxication), in case of arrhythmia, in patients with pacemakers, when associated drugs are capable of causing similar adverse effects; to better manage a digitalis treatment in a high risk patient (unstable renal function, advanced myocardial disease, chronic obstructive disease) [fr

    A lower serum cholesterol level was recently shown to be one of the causes of stroke in an epidemiological study. Spontaneously hypertensive rats stroke-prone (SHRSP) have lower serum cholesterol levels than normotensive Wistar-Kyoto rats (WKY). To elucidate the mechanisms responsible for the lower serum cholesterol levels in SHRSP, we determined whether the amounts of cholesterol biosynthetic enzymes or the receptor and transporter involved in cholesterol uptake and efflux in the liver were altered in SHRSP. When the mRNA levels of seven cholesterol biosynthetic enzymes were measured using real-time polymerase chain reaction (PCR), farnesyl pyrophosphate synthase and squalene epoxidase (SQE) levels in the liver of SHRSP were significantly lower than those in WKY. SQE protein levels were significantly reduced in tissues other than the brain of SHRSP. No significant differences were observed in low-density lipoprotein (LDL) receptor (uptake of serum LDL-cholesterol) or ATP-binding cassette transporter A1 (efflux of cholesterol from the liver/formation of high-density lipoprotein (HDL)) protein levels in the liver and testis between SHRSP and WKY, whereas scavenger receptor class B type 1 (SRB1: uptake of serum HDL-cholesterol) protein levels were higher in the livers of SHRSP. These results indicated that the lower protein levels of SQE and higher protein levels of SRB1 in the liver were involved in the reduced serum cholesterol levels in SHRSP.

    concentrations of BOPP were randomly distributed throughout the cytoplasm; however, larger lysosomes containing BOPP were concentrated around the cell nucleus. Little or no BOPP accumulated in the cell nucleus. At incubation concentrations of 20 and 40 μg/ml (24-h time point), BOPP uptake in SF-767 cells was reduced in LPDS compared with NS (66% reduction). A similar result was observed for normal human fibroblasts (AG-1522 cells, 40 μg/ml, 24 h). At 40 μg/ml, in both NS and LPDS at 24 h, BOPP accumulation in LDL receptor-deficient human fibroblasts (GM019-15C cells) was reduced relative to AG-1522 cells. BOPP accumulation in GM019-15C cells (40 μg/ml, 24 h) was not affected by serum lipoprotein levels. Conclusion: In cell culture, BOPP is taken up by human glioma cells via the LDL pathway and is compartmentalized into cellular lysosomes. Knowledge of this mechanism of BOPP uptake and retention will be important in attempts to modify toxicity and efficacy of this drug

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

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

    Biochemical variables in blood were measured in venous blood samples from 38 to 72 Space Shuttle astronauts before and immediately after flights of 2 to 11 days. Mean pre- and postflight values were compared using the paired t-test or the Wilcoxon signed-rank test. The largest change in serum enzymes was a 21% increase (P = .0014) in gamma-glutamyl-transpeptidase, which may have been related to stress. The median value of apolipoprotein (apo) A-I decreased from 152 to 127 mg/dL (P < .0001), but the change in apo B (77 to 73 mg/dL) was not statistically significant, and the mean apo A-I/apo B ratio remained well above 1.5. A decrease in dietary fat and cholesterol intake during shuttle missions may have been a cause of the change in apo A-I. Twelve of the 16 nonenzyme serum proteins measured were significantly elevated (P < .05), possibly because of hemoconcentration and increased protein catabolism. The 56% increase in haptoglobin may be related to release of suppressed erythropoiesis at landing.

    The responsiveness of the human mammary carcinoma cell line MCF-7 to estradiol and tamoxifen treatment has been studied in different culture conditions. Cells from exponentially growing cultures were compared with cells in their initial cycles after replating from confluent cultures (''confluent-log'' cells). It has been observed that estradiol stimulation of tritiated thymidine incorporation decreases with cell density and that ''confluent-log'' cells are estrogen unresponsive for a period of four cell cycles in serum-free medium conditions. On the other hand, growth of cells replated from exponentially growing, as well as from confluent cultures, can be inhibited by tamoxifen or a combined treatment with tamoxifen and the progestin levonorgestrel. This growth inhibitory effect can be rescued by estradiol when cells are replated from exponentially growing cultures. The growth inhibitory effect cannot be rescued by estradiol alone (10(-10) to 10(-8) M) when cells are replated from confluent cultures. In this condition, the addition of steroid depleted serum is necessary to reverse the state of estradiol unresponsiveness. Serum can be replaced by high density lipoproteins but not by low density lipoproteins or lipoprotein deficient serum. The present data show that estradiol and HDL interact in the control of MCF-7 cell proliferation

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

    The impact of the 24-h ultramarathon race on homocysteine (Hcy) and oxidized low-density lipoprotein (oxLDL) levels, two well-recognized cardiovascular risk factors, has not been deeply investigated. Similarly, no information exists on paraoxonase 1 (PON1), an antioxidant enzyme associated with high-density lipoproteins, which may detoxify oxLDL and Hcy-thiolactone, hence preventing their proatherogenic action. Taking this into account, a competitive 24-h ultramarathon race was organized in Reggio-Emilia (Italy) recruiting professional runners (n = 14) from the Italian Ultramarathon and Trail Association. Blood samples were collected from each participant before, during (14 h), and immediately after (24 h) the competition, thus to monitor the serum changes in Hcy, oxLDL, and PON1 levels, as well as other oxidative stress-related parameters, namely reactive oxygen metabolites (ROM) and total antioxidant capacity (PAT). As a result, a significant PON1 increase was recorded after 14 h of racing that persisted until the end of the performance. The same trend was observed for PAT values, which positively correlated to PON1 levels (R = 0.643, P<0.001). Hcy, oxLDL, and ROM remained almost unchanged throughout the competition. In conclusion, the present study suggested a protective role of PON1 in sustaining the antioxidant defense system and contrasting lipoprotein oxidative modifications over the 24-h race, and did not specifically evidence either Hcy or oxLDL accumulation in such challenging sporting events.

    2016-11-01

    To investigate the association between the presence of Porphyromonas gingivalis-induced immunoglobulin G antibodies and the high-density lipoprotein (HDL) level. A total of 108 individuals were examined. The presence of P. gingivalis was detected using primers designed to target the 16S rRNA gene sequence. Peripheral blood was collected from each subject to determine the levels of P. gingivalis-induced IgG1 and IgG2 serum antibodies. The HDL levels were determined using fully enzymatic methods. A higher proportion of periodontitis patients had high levels of P. gingivalis-induced IgG1 and IgG2, and the proportion of subjects with a HDL level of chronic periodontitis patients. In the unadjusted regression model, the presence of high levels of P. gingivalis-induced IgG2 was associated with a HDL level of periodontitis patients with high levels of P. gingivalis-induced IgG2 showed 3.2 more chances of having pathological HDL levels (odds ratio = 3.2, 95% confidence interval = 1.2-9.8). High levels of P. gingivalis-induced IgG2 were associated with low HDL concentrations in patients with periodontitis, which suggests that the response of the host to periodontal infection may play an important role in the pathogenesis of cardiovascular diseases. © 2015 Wiley Publishing Asia Pty Ltd.

    Several lipoprotein lipase (LPL) gene polymorphisms have been found associated with fasting lipid levels, but their impact on coronary heart disease (CHD) is less clearly established. We investigated associations of LPL polymorphisms (HindIII, PvuII, Ser447-->Ter) and the newly described mutation Asn291-->Ser with the risk of myocardial infarction (MI), severity of atherosclerosis, and fasting plasma lipoprotein concentrations in the ECTIM study (614 patients and 733 controls). The Ter447 allele had a lowering effect on triglycerides (P Ser polymorphisms did not exhibit any significant association with the biochemical traits examined. The HindIII genotype distributions differed between cases and controls, the odds ratios for MI associated with H+H+ and H+H- genotypes being 2.05 (P Ter and MI suggested that this mutation was unlikely to be the cause of the association found with HindIII. In some cases, the severity of atherosclerosis assessed by coronarography increased with the presence of P+ allele (coronary scores: 1.41, 1.57, and 1.64 in P-P-, P-P+, and P+P+ individuals respectively, P Ser mutation (1.58 vs. 1.90, P = 0.06). Our results suggest that the LPL gene is involved in the determination of lipoprotein profiles, the predisposition to CHD, and the severity of atherosclerosis.

    Full Text Available Lipoprotein(a, an LDL variant, has been claimed to have a role in atherogenesis and therefore coronary artery disease (CAD. However, its production and atherogenecity seems to vary among ethnic groups. In order to study the possible correlation between levels of Lp(a and CAD in Iranian patients who suffered myocardial infarction (MI, a case-control study was carried out on 120 MI patients and 120 matched healthy subjects. Levels of Lp(a were significantly higher in the MI patients than the control group (P < 0.0001, which demonstrates a possible correlation between levels of Lp(a and CAD. Estimation of Lp (a may be helpful in evaluating the risk of CAD, particularly in those patients with borderline levels of triglycerides and cholesterol.

    2004-06-01

    Background/Objective: The purpose of this study is to testthe extent that individual lipoprotein responses to diet can beattributed to genes in the presence of divergent exercise levels.Design:Twenty-eight pairs of male monozygotic twins (one mostly sedentary, theother running an average of 50 km/week more than the sedentary twin) wentfrom a 6-week 40 percent fat diet to a 6-week 20 percent fat diet in acrossover design. The diets reduced fat primarily by reducing saturatedand polyunsaturated fat (both from 14 percent to 4 percent), whileincreasing carbohydrate intake from 45 percent to 65 percent. Results:Despite the twins' differences in physical activity, the dietarymanipulation produced significantly correlated changes (P<0.05) in thetwin's total cholesterol (r=0.56), low-density lipoprotein(LDL)-cholesterol (r=0.70), large, buoyant LDL (Sf7-12, r=0.52), apo A-I(r=0.49), Lp(a) (r=0.49), electrophoresis measurements of LDL-I (LDLsbetween 26 and 28.5 nm diameter, r=0.48), LDL-IIB (25.2-24.6 nm, r=0.54),LDL-IV (22-24.1 nm, r=0.50), and body weights (r=0.41). Replacing fatswith carbohydrates significantly decreased the size and ultracentrifugeflotation rate of the major LDL, the LDL mass concentrations of Sf7-12,LDL-I, high-density lipoprotein (HDL)-cholesterol and apo A-I, andsignificantly increased LDL-IIIA (24.7-25.5 nm diameter) and Lp(a).Conclusions: Even in the presence of extreme exercise difference, genessignificantly affect changes in LDL, apo A-I, Lp(a) and body weight whendietary fats are replaced with carbohydrates.

    To determine the effects of fasting during the month of Ramadan on fetal development and maternal serum cortisol and lipid profile. This study was performed in Obstetrics and Gynecology Department of Gaziantep University Hospital, between 23 September 2006 and 23 October 2006 (during the month of Ramadan). Thirty-six consecutive healthy women with uncomplicated pregnancies of 20 weeks or more, who were fasting during Ramadan, were included in the study group (group 1). The control group (group 2) consisted of 29 healthy pregnant women, who were not fasting during the study period. For evaluating Ramadan's effect on fetus, Doppler ultrasonography was performed on all subjects in the beginning and then once a week until the end of Ramadan for the following measurements: increase of fetal biparietal diameter (BPD), increase of fetal femur length (FL), increase of estimated fetal body weight (EFBW), fetal biophysical profile (BPP), amniotic fluid index (AFI), and umbilical artery systole/diastole (S/D) ratio. Maternal serum cortisol, triglyceride, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), very low density lipoprotein (VLDL), and LDL/HDL ratio were also evaluated before and after Ramadan. No significant difference was found between the two groups for the fetal age, maternal weight gain (kilogram), estimated fetal weight gain (EFWG), fetal BPP, AFI, and umbilical artery S/D ratio. In the fasting group, the maternal serum cortisol levels on day 20 were significantly higher than the initial levels obtained 1 week prior to Ramadan (p Ramadan. HDL levels showed a slight increase, but LDL/HDL ratios were significantly decreased in fasting group (p Ramadan. No untoward effect of Ramadan was observed on intrauterine fetal development.

    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.

  18. Effect of Two Lipoprotein (a-Associated Genetic Variants on Plasminogen Levels and Fibrinolysis

    2016-11-01

    Full Text Available Two genetic variants (rs3798220 and rs10455872 in the apolipoprotein (a gene (LPA have been implicated in cardiovascular disease (CVD, presumably through their association with lipoprotein (a [Lp(a] levels. While Lp(a is recognized as a lipoprotein with atherogenic and thrombogenic characteristics, it is unclear whether or not the two Lp(a-associated genetic variants are also associated with markers of thrombosis (i.e., plasminogen levels and fibrinolysis. In the present study, we genotyped the two genetic variants in 2919 subjects of the Old Order Amish (OOA and recruited 146 subjects according to the carrier and noncarrier status for rs3798220 and rs10455872, and also matched for gender and age. We measured plasma Lp(a and plasminogen levels in these subjects, and found that the concentrations of plasma Lp(a were 2.62- and 1.73-fold higher in minor allele carriers of rs3798220 and rs10455872, respectively, compared with noncarriers (P = 2.04 × 10−17 and P = 1.64 × 10−6, respectively. By contrast, there was no difference in plasminogen concentrations between carriers and noncarriers of rs3798220 and rs10455872. Furthermore, we observed no association between carrier status of rs3798220 or rs10455872 with clot lysis time. Finally, plasminogen mRNA expression in liver samples derived from 76 Caucasian subjects was not significantly different between carriers and noncarriers of these two genetic variants. Our results provide further insight into the mechanism of action behind two genetic variants previously implicated in CVD risk and show that these polymorphisms are not major modulating factors for plasma plasminogen levels and fibrinolysis.

    A sensitive and specific double antibody radioimmunoassay for the major apolipoprotein (apoB) of rhesus (Macaca mulatta) serum very low density lipoprotein (VLDL) and low density lipoprotein (LDL) is described. The antiserum was raised to LDL (d 1.030 to 1.040 g/ml) and the LDL 2 (d 1.020 to 1.050 g/ml) was labeled with 125 I by the chloramine-T or iodine monochloride method. The assay, which was sensitive to 0.02 to 0.5 μg of LDL 2 , had an interassay coefficient of variation of 4.5%. This assay was successfully used to measure apoB in the whole serum and low density lipoproteins of control monkeys maintained on a standard Purina monkey chow (PMC) diet and of three groups of monkeys fed atherogenic diets: an average American diet, a 25% peanut oil and 2% cholesterol-supplemented PMC diet, and a 25% coconut oil and 2% cholesterol-supplemented PMC diet

Our study did not show any significant correlation between serum Mg levels and duration of HD treatment, levels of serum ALP, and plasma HCO3, Ca and P. An inverse correlation, albeit insignificant, was found between the serum Mg levels and iPTH (r=-0.30 p=0.079; also, a significant positive correlation was found between serum Mg levels and serum 25-OH Vit D levels (r= 0.40 p= 0.009. Our findings are in agreement with previous data, which suggest that factors other than serum Mg are more important in the regulation of PTH secretion in HD patients. A positive and strong association between serum Mg with 25-OH Vit D needs to be studied in greater detail.

    We examined how serum cholesterol, an established risk factor for cerebrovascular disease (CVD), relates to cognitive function in healthy middle-older aged individuals with no neurologic or CVD history. A complete lipid panel was obtained from a cohort of one hundred twenty individuals, ages 43-85, who also underwent a comprehensive neuropsychological examination. In order to reduce the number of variables and empirically identify broad cognitive domains, scores from neuropsychological tests were submitted into a factor analysis. This analysis revealed three explainable factors: Memory, Executive Function and Memory/Language. Three separate hierarchical multiple regression analyses were conducted using individual cholesterol metrics (total cholesterol, low density lipoprotein; LDL, high density lipoprotein; HDL, and triglycerides), as well as age, education, medication status (lipid lowering agents), ApoE status, and additional risk factors for CVD to predict neuropsychological function. The Memory Factor was predicted by a combination of age, LDL, and triglyceride levels; both age and triglycerides were negatively associated with factor score, while LDL levels revealed a positive relationship. Both the Executive and Memory/Language factor were only explained by education, whereby more years were associated with better performance. These results provide evidence that individual cholesterol lipoproteins and triglycerides may differentially impact cognitive function, over and above other common CVD risk factors and ApoE status. Our findings demonstrate the importance of consideration of vascular risk factors, such as cholesterol, in studies of cognitive aging.

    It is difficult to apply the proper intensity of statin for new treatment guidelines in clinical settings because of few data about the statin efficacy in Asians. We conducted a retrospective, observational study to estimate the percentage changes in lipid parameters and glucose induced by different statins. We analyzed 3854 patients including those with nondiabetes and diabetes treated at the outpatient clinic between 2003 and 2013 who were statin-naïve and maintained fixed-dose of statin for at least 18 months. Moderate- and low-intensity statin therapy was effective in reducing low-density lipoprotein cholesterol (LDL-C) to statin group. The effects of statins in elevating high-density lipoprotein cholesterol were similar in each statin groups, except the ezetimibe-simvastatin group (4.5 ± 2.1%) and high-dose atorvastatin groups (9.7 ± 3.3% and 8.7 ± 2.4% for 40 mg and 80 mg of atorvastatin/day, respectively). High-density lipoprotein cholesterol increased less and LDL-C decreased more in diabetes than in nondiabetes. There were no significant changes of fasting glucose after statin use in nondiabetic patients. Moderate- or low-intensity statin was effective enough in reaching National Cholesterol Education Program Adult Treatment Panel III LDL-C target goals in Koreans. Low-intensity statin showed around 30% LDL-C reduction from the baseline level in Koreans, which is comparable to moderate-intensity statin in new guideline.

    Hyperlipidemia is a major risk factor for cardiovascular diseases. Considering the suggested association between periodontal and cardiovascular diseases, this study sought to assess the association, if any, between serum triglyceride (TG) levels and gemfibrozil consumption with periodontal parameters. This cross-sectional study was conducted on 90 participants, including 30 individuals with a normal lipid profile (group H), 30 patients with hypertriglyceridemia and not on medication (group N), and 30 patients with hypertriglyceridemia and taking gemfibrozil over a 3-month period (group M). Periodontal parameters including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index were measured at four sites of each tooth. Serum levels of total cholesterol (TC), TG, low-density lipoprotein, and high-density lipoprotein were measured. Mean values for PD and CAL in the two hypertriglyceridemic groups were significantly higher than those of the H group (P <0.001). After controlling for confounding variables, significant linear correlations were noted between PD and BOP, PD and TC, PD and TG, and CAL and TG in each group (P <0.01). Patients with hypertriglyceridemia had worse periodontal status than healthy controls. Patients with hypertriglyceridemia who were taking gemfibrozil did not show significant differences in CAL and PD compared with untreated patients with hypertriglyceridemia.

    Full Text Available Oxidized low-density lipoprotein (LDL is thought to play an important role in the inflammatory response associated with human obesity. The purpose of this preliminary study was to determine oxidized LDL concentrations in healthy dogs and cats, and to evaluate whether obesity affects oxidized LDL concentration, using 39 cats and 19 dogs that had visited 2 different veterinary clinics in Japan. We hypothesized that oxidized LDL concentrations measured against body condition score (BCS may have a potential value in evaluating the qualities of accumulated or circulating lipids in obese dogs and cats that do not show signs of metabolic diseases. The mean oxidized LDL value in BCS3 dogs (2.4 ± 0.9 μg/dl was very similar to that of BCS5 dogs (2.2 ± 0.3 μg/dl. The mean oxidized LDL value of BCS4 dogs was 7.2 ± 10.3 μg/dl and the highest among three groups. BCS4 dogs included two dogs whose oxidized LDL values were higher than the mean oxidized LDL value of healthy humans (11.2 ± 0.3 μg/dl. On the other hand, the mean oxidized LDL value of BCS3 cats was 2.5 ± 0.9 μg/dl, and those of BCS4 and 5 cats were higher than that of BCS3, but there was no significant difference. The BCS4 cat group included one cat with a higher oxidized LDL value, and the BCS5 group also included two cats with oxidized LDL values higher than the mean oxidized LDL value of healthy humans. Interestingly, the oxidized LDL values in 2 obese dogs and 3 obese cats were indeed higher than the mean oxidized LDL value of humans with coronary artery disease (20.1 ± 1.1 μg/dl. In conclusion, this preliminary study showed reference ranges of oxidized dogs and cats against BCS. Obesity alone does not appear to have any direct effect on serum oxidized LDL values in healthy dogs and cats.

    Full Text Available Inflammatory atherosclerosis is increased in subjects with type 1 diabetes mellitus (T1DM. Normally high-density lipoproteins (HDL protect against atherosclerosis; however, in the presence of serum amyloid-A- (SAA- related inflammation this property may be reduced. Fasting blood was obtained from fifty subjects with T1DM, together with fifty age, gender and BMI matched control subjects. HDL was subfractionated into HDL2 and HDL3 by rapid ultracentrifugation. Serum-hsCRP and serum-, HDL2-, and HDL3-SAA were measured by ELISAs. Compared to control subjects, SAA was increased in T1DM subjects, nonsignificantly in serum (P=0.088, and significantly in HDL2(P=0.003 and HDL3(P=0.005. When the T1DM group were separated according to mean HbA1c (8.34%, serum-SAA and HDL3-SAA levels were higher in the T1DM subjects with HbA1c ≥ 8.34%, compared to when HbA1c was 0.05. This cross-sectional study demonstrated increased SAA-related inflammation in subjects with T1DM that was augmented by poor glycaemic control. We suggest that SAA is a useful inflammatory biomarker in T1DM, which may contribute to their increased atherosclerosis risk.

    In mammals the composition of milk changes during early lactation, with a rapid decline of fat-soluble vitamins and a continuous increase in total lipids. The mechanisms underlying this phenomenon are not well understood, but might involve selective mechanisms related to mammary uptake or secretion into the milk. Since carotenoids are specifically distributed among the lipoprotein fractions in plasma, the simultaneous determination of carotenoids in plasma, lipoprotein fractions and milk might offer an opportunity to gain insight into this phenomenon. In 21 healthy mothers carotenoids in plasma and lipoprotein fractions were investigated at day 2 and 19 and milk on day 4 and 19 after delivery. Plasma levels of alpha-tocopherol and cholesterol as well as lutein, zeaxanthin and cryptoxanthin were significantly lower later in lactation (day 19) than shortly after birth (P milk, triacylglycerol increased (P milk it was similar to the pattern found in the high density lipoprotein fraction. Based on these observations a selective mechanism might be responsible for the transfer of these components in milk involving different lipoprotein fractions at specific times of lactation.

    Although a postprandial increment in triglyceride (TG) levels is considered to be a risk factor for atherogenesis, tests (e.g., fat load) to assess postprandial changes in TG levels cannot be easily applied to clinical practice. Therefore, fasting markers that predict postprandial TG states are needed to be developed. One current candidate is lipoprotein lipase (LPL) protein, a molecule that hydrides TGs. This study investigated whether fasting LPL levels could predict postprandial TG levels. A total of 17 subjects (11 men, 6 women, mean age 52 ± 11 years) with normotriglyceridemia during fasting underwent the meal test. Several fasting parameters, including LPL, were measured for the area under the curve of postprandial TGs (AUC-TG). The subjects' mean fasting TG level was 1.30 mmol/l, and their mean LPL level was 41.6 ng/ml. The subjects' TG levels increased after loading (they peaked after two postprandial hours). Stepwise multiple regression analysis demonstrated that fasting TG levels were a predictor of the AUC-TG. In addition, fasting LPL mass levels were found to be a predictor of the AUC-TG (β = 0.65, P fasting TG levels. Fasting LPL levels may be useful to predict postprandial TG increment in this population. © 2015 Wiley Periodicals, Inc.

    Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

    Full Text Available Introduction. Physical activity and healthy diet, as lifestyle factors, are essential components in the prevention of chronic noncommunicable diseases. Impared glucose intolerance (IGT is an independent cardiovascular risk factor. Dyslipidaemia is a cardiometabolic risk factor for the development of type 2 diabetes mellitus. Objective. The aim of the study was to investigate the influence of moderate physical activity of plasma lipoprotein indicators in high-risk subjects for diabetes mellitus during one-year planned intervention. Methods. We randomly assigned 60 overweight subjects with IGT aged 30-60 years. The subjects were divided into intervention group with 30 subjects, who were intensively and individually instructed on weight reduction, nutrition and increased physical activity, and control group with 30 subjects, who were counselled, as standard, on nutrition and increased exercise. Total cholesterol (TC, LDL cholesterol (LDL-C, HDL cholesterol (HDL-C and triglycerides (Tg were measured at the beginning of the study, and at 2 months, 6 months, and at the end of the study (12 months. Results. Compared to the beginning of the study, after 2 and 6 months there was no statistically significant difference in serum lipid values. After 12 months, the average values of the measured lipid levels in the intervention group decreased by 18.36% for TC, 27.3% for LDL-C, and 34.2% for Tg (compared to 10.27%, 13.45%, and 10.4%, respectively in the control group. Value of HDL-C in the intervention group increased by 19.12%, and decreased in the control group by 1.48%. Total/HDL-C ratio was reduced by 30.6% and LDL-C/H by 38.1% in the intervention group (compared to 12.36%, and 15.9% in the control group. After 12 months, significantly greater decrease in TC (p<0.01, LDL-C (p<0.01 and Tg (p<0.0001 and significantly greater increase in HDL-C (p<0.05 was detected in the intervention group compared to the control group. Conclusion. Plasma lipoproteins can

    Low plasma high-density lipoprotein cholesterol (HDL-C) levels are a strong, independent, but poorly understood risk factor for cardiovascular disease (CVD). Although this atherogenic lipid abnormality has been widely reported in Australia's Indigenous peoples, Aboriginal and Torres Strait Islanders, the evidence has not come under systematic review. This review therefore examines published data for Indigenous Australians reporting 1) mean HDL-C levels for both sexes and 2) factors associated with low HDL-C. PubMed, Medline and Informit ATSI Health databases were systematically searched between 1950 and 2012 for studies on Indigenous Australians reporting mean HDL-C levels in both sexes. Retrieved studies were evaluated by standard criteria. Low HDL-C was defined as: Indigenous populations living in rural and remote communities. Inverse associations between HDL-C and central obesity, diabetes prevalence and inflammatory markers suggest a particularly adverse CVD risk factor profile. An absence of sex dichotomy in HDL-C levels warrants further investigation.

    Cardiovascular disease is the leading cause of morbidity and mortality in hemodialysis patients; the increased risk of cardiovascular disease is due to accelerated atherosclerosis, inflammation and impaired lipoprotein metabolism. We aimed to evaluate lipoprotein-associated phospholipase A2 (Lp-PLA2) and some pro-inflammatory aspects of the lipoprotein profile in dialyzed patients in order to evaluate the relationship with the accelerated atherosclerosis and vascular accidents. In 102 dialysis patients and 40 non-uremic controls, we investigated the lipoprotein plasma profile, high sensitivity C-reactive protein (CRP), ceruloplasmin and serum amyloid A protein (SAA), and followed patients for 1 year to analyze the risk of acute cardiovascular events. Total cholesterol, low-density lipoprotein and high-density lipoprotein plasma levels were significantly lower in uremic patients than controls, whereas CRP, SAA, ceruloplasmin, Lp-PLA2 and their ratio with apolipoprotein A1 were significantly higher. Patients with Lp-PLA2 levels >194 nmol/min/ml had more acute cardiovascular events than patients with lower values. Our results show that in dialysis subjects: (1) low-density lipoproteins show a more atherogenic phenotype than in the general population; (2) high-density lipoproteins are less anti-inflammatory; (3) Lp-PLA2 could potentially be used to evaluate cardiovascular risk.

    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.

    OBJECTIVE: There are no recommendations in guidelines on measuring lipoprotein(a) in the fasting or nonfasting state, or on the influence of inflammation. We tested the hypotheses that lipoprotein(a) levels change only minimally in response to normal food intake, and to inflammation. Also, we...... tested whether normal food intake or inflammation influenced lipoprotein(a)'s ability to predict ischemic heart disease. METHODS: We studied 34 829 individuals from the Danish general population using the Copenhagen General Population Study and the Copenhagen City Heart Study. RESULTS: Lipoprotein......(a) levels did not change in response to normal food intake: median fasting levels were 17.3 mg/dL, while median levels at 3-4 h since last meal were 19.4 mg/dL(p = 0.38). Lipoprotein(a) levels increased minimally with increasing levels of C-reactive protein(CRP): median lipoprotein(a) levels at CRP

    There have been inconsistent reports on the relationships between lipids and suicidality, and studies conducted in older adults are rare. This study examined associations between serum lipid levels and suicidal ideation in an older population. This study used data obtained from a representative Korean sample of 4265 people age 65 years or older who completed a self-administered questionnaire about suicidal ideation over the last year. The fasting serum concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides were measured and categorized into lower, intermediate (reference), and upper quartiles. A complex sample logistic regression stratified by gender was performed to determine the associations between serum lipid levels and suicidal ideation after controlling for covariates including age, education, marital status, current smoking, alcohol drinking, body mass index, hypertension, diabetes, diagnosed depression, antidepressant use, and lipid-lowering therapies. In this study, the prevalence of suicidal ideation in an older Korean population was 22.9% (SE=0.9%). The prevalence was significantly higher in women than in men, 27.7% (1.2%) vs. 15.9% (1.1%) respectively. After adjusting for covariates, lower triglyceride levels were significantly associated with a decreased risk of suicidal ideation (OR=0.65; 95% CI=0.43-0.99) among men but no significant associations were observed among women. Additionally, there were no significant associations between any other measure of cholesterol levels and suicidal ideation in either men or women. Cross-sectional design cannot infer temporality or the effects of changes in variables. These results support the association between lower triglyceride levels and a reduced risk of suicidal ideation among Korean men over 65. Further studies are necessary to investigate gender difference and the biological mechanism. Copyright © 2015 Elsevier B.V. All rights

  1. Novel mechanism by which probucol lowers low density lipoprotein levels demonstrated in the LDL receptor-deficient rabbit

    Treatment of low density lipoprotein (LDL) receptor-deficient rabbits (WHHL rabbits) with probucol (1% w/w in a chow diet) lowered their LDL-cholesterol levels by 36%, consonant with the reported effectiveness of the drug in patients deficient in the LDL receptor. Initial studies of LDL fractional catabolic rate (FCR) using 125 I-labeled LDL prepared from the serum of untreated WHHL rabbits showed no difference between probucol-treated WHHL rabbits and untreated WHHL rabbits. When, however, 125 I-labeled LDL was prepared from donor WHHL rabbits under treatment with probucol and injected back into them, the FCR was found to be increased by about 50% above that measured simultaneously using 131 I-labeled LDL prepared from untreated WHHL donors. The labeled LDL from probucol-treated donors was also metabolized more rapidly than that from untreated donors when injected into untreated WHHL rabbits or into untreated wild-type New Zealand White rabbits. Finally, it was shown that rabbit skin fibroblasts in culture degraded labeled LDL prepared from probucol-treated WHHL rabbits more rapidly than that prepared from untreated WHHL donors. This was true both for normal rabbit fibroblasts and also for WHHL skin fibroblasts, although the absolute degradation rates in the latter were, of course, much lower for both forms of LDL. The data indicate that a major mechanism by which probucol lowers LDL levels relates not to changes in the cellular mechanisms for LDL uptake or to changes in LDL production but rather to intrinsic changes in the structure and metabolism of the plasma LDL of the probucol-treated animal

    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.

    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.

    The current study was designed to investigate the association between serum thyroid hormones and thyroid-stimulating hormone (TSH) levels with lipid profile in depressive disorder. A total of 370 depressive individuals aged 18 years and above were recruited in this cross-section study. All participants underwent a Structured Clinical Interview for DSM-IV (SCID) and recorded the duration of their symptoms. The serum levels of total cholesterol (TCH), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), lipoprotein A (Lp(a)), high-sensitivity C-reactive protein (hsCRP), free thyroxine (FT4), free triiodothyronine (FT3) and TSH levels were determined and the ratios of TCH/HDL-C were assessed. Depressed subjects with a symptom duration ≥3 years had higher TG levels, increased TCH/HDL-C ratios and lower levels of HDL-C, FT4 and TSH compared with depressive patients with a symptom duration <3 years. Correlation analysis displayed that TSH is positively and significantly associated with TCH and LDL-C (p<0.05); the above FT4 and FT3 are negatively, significantly and respectively associated with TCH/HDL-C (p<0.05) and TCH, HDL-C, LDL-C (p<0.05). Multiple linear regression analysis indicated that serum TG and TSH levels are associated with depressive symptom duration. According to our results,These findings indicate that low serum TSH levels are associated with lipid profile, TG and TSH levels have significant association with symptom duration in depressive patients.

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

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

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

    This study compared the lipid profile of women runners with menstrual cycle irregularities with their normally menstruating counterparts. Relationships among selected steroid hormones and serum lipid levels in 10 eumenorrheic (EU) and 8 oligo-/amenorrheic (O/A) women runners and 6 eumenorrheic controls (CON) were examined. Serum 17 beta-estradiol (E2), progesterone (Prog), and dehydroepiandrosterone-sulfate (DHEAS) concentrations were determined in daily blood samples for 21 days, and integrated concentrations were calculated. Fasting blood samples were analyzed for total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), HDL2, HDL3, triglycerides (Trig), and apolipoproteins A-1, A-II, and B. The O/A group had significantly lower E2 and Prog than EU or CON groups. Women in the CON group had lower HDL-C and HDL3 than the runners. With all women grouped together, E2 was not significantly correlated with any measured blood lipid parameters. On the other hand, DHEAS was significantly correlated with HDL-C, HDL2, and apolipoprotein A-I. These data demonstrate that women runners, regardless of menstrual cycle status, exhibit higher HDL-C concentrations than CON and supports previous research reporting a positive association between DHEAS and HDL-C.

    The effects of 3 wk on a diet rich in monounsaturated rapeseed oil were compared with those of a diet containing sunflower oil within a lipid-lowering diet. Ninety-five subjects with moderate hyperlipoproteinemia were randomly assigned to one of the two well-controlled diets prepared at the hospital kitchen. Total serum, low-density- and high-density-lipoprotein cholesterol concentrations decreased by 15%, 16%, and 11% (P oil diet and by 16%, 14%, and 13% (P oil diet. Serum triglycerides decreased more markedly (by 29%, P oil than on the rapeseed oil diet (14%, P oil diet but decreased on the sunflower oil diet. There was an increase in the alpha-tocopherol concentrations after both diets. The findings indicate that low erucic acid rapeseed oil can replace oils and fats rich in polyunsaturated fatty acids in a lipid-lowering diet.

    Background Although the health effects of vitamin C are well known, its physiological effect on serum lipoproteins and microRNA still remain to be investigated, especially daily consumption of a high dosage. Objectives To investigate the physiological effect of vitamin C on serum lipoprotein metabolism in terms of its anti-oxidant and anti-glycation activities, and gene expression via microRNA regulation. Methods We analyzed blood parameters and lipoprotein parameters in young subjects (n = 46, 22 ± 2 years old) including smokers who consumed a high dose of vitamin C (1250 mg) daily for 8 weeks. Results Antioxidant activity of serum was enhanced with the elevation of Vit C content in plasma during 8 weeks consumption. In the LDL fraction, the apo-B48 band disappeared at 8 weeks post-consumption in all subjects. In the HDL fraction, apoA-I expression was enhanced by 20% at 8 weeks, especially in male smokers. In the lipoprotein fraction, all subjects showed significantly reduced contents of advanced glycated end products and reactive oxygen species (ROS). Triglyceride (TG) contents in each LDL and HDL fraction were significantly reduced in all groups following the Vit C consumption, suggesting that the lipoprotein was changed to be more anti-inflammatory and atherogenic properties. Phagocytosis of LDL, which was purified from each individual, into macrophages was significantly reduced at 8-weeks post-consumption of vitamin C. Anti-inflammatory and anti-senescence effects of HDL from all subjects were enhanced after the 8-weeks consumption. The expression level of microRNA 155 in HDL3 was reduced by 49% and 75% in non-smokers and smokers, respectively. Conclusion The daily consumption of a high dose of vitamin C for 8 weeks resulted in enhanced anti-senescence and anti-atherosclerotic effects via an improvement of lipoprotein parameters and microRNA expression through anti-oxidation and anti-glycation, especially in smokers.

    To investigate the association between circulating oxidized low-density lipoprotein (ox-LDL) levels and progression of subclinical atherosclerosis and to examine whether this link is independent of other low-density lipoprotein (LDL)-related parameters. Totally, 804 subjects who were free of cardiovascular disease at baseline completed risk factor surveys and carotid ultrasound measurements in 2002 and 2012. Modified Poisson regression was performed to examine the association between baseline serum ox-LDL levels and the 10-year risk of progression of carotid atherosclerosis which was defined as the development of at least one new plaque in a previously plaque-free carotid segment at re-examination. The mean age of the subjects was 58.6±7.7 years at baseline and 43.3% were men. A total of 504 (62.7%) subjects had carotid plaque progression at re-examination. Subjects in the intermediate and highest tertiles of ox-LDL had a significantly higher adjusted risk of atherosclerosis progression than those in the lowest tertile [relative risk (95% confidence interval) 1.17 (1.01-1.34) for the intermediate tertile and 1.23 (1.07-1.42) for the highest tertile]. This association was independent of baseline levels of LDL-C, total LDL particle number, and small LDL particle number. This study demonstrates that serum ox-LDL levels predict 10-year progression of subclinical atherosclerosis. Moreover, this effect is independent of the cholesterol content, the number, and the size of LDL particles.

    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

    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.

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

    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.

    Serum high-sensitivity C-reactive protein (hsC-rp) is a non-specific marker of inflammation. Elevated hsC-rp levels are found in subjects with cardiovascular diseases (CVDs). Periodontitis may influence hsC-rp levels. To assess periodontal status and hsC-rp serum levels in consecutive subjects hospitalized and diagnosed with acute myocardial infarction (AMI) (n=85) and in a group of carefully matched subjects (gender, age social, ethnic, and smoking habits) without clinical evidence of CVD (n=63). hsC-rp levels, other routine serum values, and clinical periodontal conditions were studied. Subjects with AMI had higher hsC-rp levels than control subjects (pperiodontitis (30% or more sites with>4.0 mm loss of alveolar bone) had serum hsC-rp>1.8 mg/l was 1.5 (95% CI: 1.1-7.3, pperiodontal parameters in an explanatory model to hsC-rp values. Only the serum leucocyte (white blood cell (WBC)) counts were explanatory to hsC-rp values (beta standard coefficient=0.45, t=3.2, pperiodontitis (pperiodontitis in subjects with no evidence of CVD. (3) Periodontal parameters are not explanatory to elevated serum hsC-rp values if serum WBC and low-density lipoprotein counts are included in the regression model.

    Measurements of the serum Vitamin B 12 concentrations of 49 black and 49 white healthy adults demonstrate a significantly higher mean serum Vitamin B 12 level in blacks when compared to whites. The reason for this difference appears to be genetic, although environmental factors may also be involved. It is suggested that clinical laboratories should establish their own separate reference values of serum Vitamin B 12 for blacks and whites in order to prevent misinterpretation of test results

    Studies have shown that soy protein reduces some atherogenic lipid and lipoprotein concentrations, although lipoprotein(a) concentrations may be increased. The dose response of soy protein has not been established; neither has its effect on plasma total homocysteine. Our objective was to evaluate the effect of 2 doses of soy protein on lipid, lipoprotein, and homocysteine concentrations. Four to 24 wk after being instructed to consume a lipid-lowering diet, 130 men and women with LDL-cholesterol concentrations > or = 4 mmol/L were studied during a parallel group trial in which 4 interventions were assigned randomly. Thirty grams isolated soy protein (ISP) and 10 g cotyledon fiber or 50 g ISP and 16.6 g cotyledon fiber or equivalent doses of casein and cellulose were consumed daily as a beverage for 16 wk. When the 2 groups who consumed ISP were compared with the 2 groups who consumed casein, the differences in the net changes from baseline to week 16 in the concentrations of LDL cholesterol and plasma total homocysteine were -0.26 mmol/L (95% CI: -0.43, -0.09 mmol/L; P = 0.01) and -0.8 micromol/L (-1.4, -0.2 micromol/L; P = 0.005), respectively. The effect of the ISP dose was not significant. There were no significant differences between the 2 ISP and the 2 casein groups in changes in lipoprotein(a), HDL-cholesterol, or triacylglycerol concentrations. Adding 30-50 g soy protein/d to a lipid-lowering diet significantly reduced LDL-cholesterol concentrations without increasing lipoprotein(a) concentrations. Plasma total homocysteine concentrations also decreased, suggesting a novel, possibly antiatherosclerotic effect.

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

    Full Text Available Febrile convulsions (FC are the most common neurologic disorder in children 6-60 months of age. Zinc (Zn and copper (Cu play role as cofactors in more than 300 enzymatic activities significantly. The aim of this study was to evaluate the relationship serum levels of Zn and Cu with seizure occurrence in febrile children. In this case-control study, 270 children with 6 month to 6 years were evaluated. The patients were enrolled in three groups: a children with febrile convulsion, b febrile children without convulsion and c healthy ones. After recording of all patients’ characteristics, 5 mL blood was taken from peripheral vessels at the first 12 hours of hospitalization. Absorption of all samples was read by BRAIC (Rayleigh instrument company, WFX-130 model with calibration diagram, considering samples dilution levels. The mean of serum Zn levels in children with FC were significantly lower than other two groups. Mean serum Cu levels in children with FC and non-FC patients were significantly higher than healthy children. No meaningful differences were observed in serum levels of Zn and Cu among the girl or boy cases. This study showed significant lower serum zinc level in children with febrile seizure and meaningful higher serum copper level than control group cases. There was no significant difference in level of serum zinc and copper in term of sex.

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

    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

    Ghee, also known as clarified butter, has been utilized for thousands of years in Ayurveda as a therapeutic agent. In ancient India, ghee was the preferred cooking oil. In the last several decades, ghee has been implicated in the increased prevalence of coronary artery disease (CAD) in Asian Indians due to its content of saturated fatty acids and cholesterol and, in heated ghee, cholesterol oxidation products. Our previous research on Sprague-Dawley outbred rats, which serve as a model for the general population, showed no effect of 5 and 10% ghee-supplemented diets on serum cholesterol and triglycerides. However, in Fischer inbred rats, which serve as a model for genetic predisposition to diseases, results of our previous research showed an increase in serum total cholesterol and triglyceride levels when fed a 10% ghee-supplemented diet. In the present study, we investigated the effect of 10% dietary ghee on microsomal lipid peroxidation, as well as serum lipid levels in Fischer inbred rats to assess the effect of ghee on free radical mediated processes that are implicated in many chronic diseases including cardiovascular disease. Results showed that 10% dietary ghee fed for 4 weeks did not have any significant effect on levels of serum total cholesterol, but did increase triglyceride levels in Fischer inbred rats. Ghee at a level of 10% in the diet did not increase liver microsomal lipid peroxidation or liver microsomal lipid peroxide levels. Animal studies have demonstrated many beneficial effects of ghee, including dose-dependent decreases in serum total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides; decreased liver total cholesterol, triglycerides, and cholesterol esters; and a lower level of nonenzymatic-induced lipid peroxidation in liver homogenate. Similar results were seen with heated (oxidized) ghee which contains cholesterol oxidation products. A preliminary clinical study showed that high doses of

    Ketogenic diet (KD) is one of the most effective therapies for intractable epilepsy. Olive oil is rich in monounsaturated fatty acids and antioxidant molecules and has some beneficial effects on lipid profile, inflammation and oxidant status. The aim of this study was to evaluate the serum lipid levels of children who were receiving olive oil-based KD for intractable seizures at least 1 year. 121 patients (mean age 7.45 ± 4.21 years, 57 girls) were enrolled. At baseline and post-treatment 1, 3, 6, and 12 months body mass index-SDS, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol and triglyceride levels were measured. Repeated measure ANOVA with post hoc Bonferroni correction was used for data analysis. The mean duration of KD was 15.4 ± 4.1 months. Mean total cholesterol, LDL-cholesterol and triglyceride levels were significantly higher at 1st, 3rd, 6th and 12th months of the KD treatment, compared to pre-treatment levels (p = 0.001), but showed no difference among during-treatment measurements. Mean body mass index-SDS and HDL-cholesterol levels were not different among the baseline and follow-up time points (p = 0.113 and p = 0.067, respectively). No child in this study discontinued the KD because of dyslipidemia. Even if rich in olive oil, high-fat KD causes significant increase in LDL-cholesterol and triglyceride levels. More studies are needed to determine the effect of KD on serum lipids in children using different fat sources in the diet.

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

    Full Text Available Background. Lipoprotein (a [Lp(a] is an independent risk factor for cardiovascular disease (CVD in Non-Hispanic Whites (NHW. There are known racial/ethnic differences in Lp(a levels, and the association of Lp(a with CVD outcomes has not been examined in Asian Americans in the USA. Objective. We hypothesized that Lp(a levels would differ in Asian Indians and Chinese Americans when compared to NHW and that the relationship between Lp(a and CVD outcomes would be different in these Asian racial/ethnic subgroups when compared to NHW. Methods. We studied the outpatient electronic health records of 2022 NHW, 295 Asian Indians, and 151 Chinese adults age ≥18 y in Northern California in whom Lp(a levels were assessed during routine clinical care from 2001 to 2008, excluding those who had received prescriptions for niacin (14.6%. Nonparametric methods were used to compare median Lp(a levels. Significance was assessed at the P<.0001 level to account for multiple comparisons. CVD outcomes were defined as ischemic heart disease (IHD (265 events, stroke (122, or peripheral vascular disease (PVD (87. We used logistic regression to determine the relationship between Lp(a and CVD outcomes. Results. Both Asian Indians (36 nmol/L and NHW (29 nmol/L had higher median Lp(a levels than Chinese (22 nmol/L, P≤.0001 and P=.0032. When stratified by sex, the differences in median Lp(a between these groups persisted in the 1761 men (AI v CH: P=.001, NHW v CH: P=.0018 but were not statistically significant in the 1130 women (AI v CH: P=.0402, NHW v CH: P=.0761. Asian Indians (OR=2.0 and Chinese (OR=4.8 exhibited a trend towards greater risk of IHD with high Lp(a levels than NHW (OR=1.4, but no relationship was statistically significant. Conclusion. Asian Indian and NHW men have higher Lp(a values than Chinese men, with a trend toward, similar associations in women. High Lp(a may be more strongly associated with IHD in Asian Indians and Chinese, although we did

    The genes encoding three lipoproteins of Vibrio cholerae were identified by a combination of DNA sequence analysis and [ 3 H]palmitate labeling of hybrid proteins encoded by TnphoA gene fusions. The expression of these three lipoproteins, TagA, AcfD, and TcpC, was controlled by ToxR, the cholera toxin transcriptional activator. The involvement of other bacterial lipoproteins in conferring resistance ot the bactericidal effects of complement prompted us to examine this possibility in V. cholerae. Remarkably, mutations in toxR and tcp genes (including tcpC), involved in the biogenesis of the toxin coregulated pili, rendered V. cholerae about 10 4 - 10 6 times more sensitive to the vibriocidal activity of antibody and complement. Since V. cholerae is a noninvasive organism and toxR and tcp mutants are highly defective in intestinal colonization in animals and humans, these results raise the possibility that resistance to a gut-associated, complement-like bactericidal activity may be a major virulence determinant of V. cholerae and other enterobacterial species

    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

    There is some evidence that low lipid levels cause suicide in depressed patients. The purpose of this study was to identify whether low serum lipid levels are associated with suicide ideation or are correlated with central serotonin function. Auditory processing for the loudness dependence of auditory evoked potentials (LDAEP) was measured in 73 outpatients with major depressive disorder. The Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI) were administered on the same day as measurement of the LDAEP. In addition, serum levels of total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels were measured. All subjects had received antidepressant monotherapy. The depressed subjects were divided into those with and without suicide ideation according to the score for HAMD item 3 or BDI item 9. TG levels differed significantly between the two groups, whereas body mass index (BMI), total cholesterol, LDL, HDL, and LDAEP did not. The scores for HAMD item 3 and BDI item 9 were negatively correlated with TG levels (p=0.045 and 0.026, respectively). The LDAEP was negatively correlated with TG levels (p=0.012). Although there was tendency toward a negative correlation between the LDAEP and serum LDL, it did not reach statistical significance (p=0.068). The cross-sectional design of this study means that baseline serum lipid levels were not measured. The findings of this study revealed a relationship between TG and suicide ideation that is independent of both BMI and body weight. Furthermore, serum lipid levels were associated with central serotonergic activity, as assessed using the LDAEP. Copyright © 2014 Elsevier B.V. All rights reserved.

    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 Introduction. Folk dance is a form of physical activity which helps develop the ability to use the whole body in a coordinated way with music, and folk dancers’ characteristics vary according to the particular type of dance practised in a given geographic region. The aims of the study were to evaluate the effects of 12-week folk dance training on blood oxidative stress level, lipids, lipoproteins, as well as muscle damage markers and to define some physical and physiological properties of folk dancers. Material and methods. Thirty-eight healthy male folk dancers aged 21-28 years having an average of 11 years of dance training experience voluntarily participated in the study. All of the physical and physiological measurements and the blood analysis were performed twice, before and after the training period which focused on different regional dances (Caucasus, Bar, Zeybek, Spoon Dance, Thracian dances, and Horon. The training was done 2 hours per day (a total of 10 hours a week, during a 12-week-long period. Results. All the blood parameters were found to be within the specified reference ranges. The training programme had no significant effect on the blood lipid profile, whereas it was found to have positive effects on body fat (p ≤ 0.012, peak oxygen consumption (VO2peak; p = 0.000, muscle damage markers (creatine kinase, Δ% = −19.6, and total antioxidant capacity (p ≤ 0.002. Conclusions. Regular folk dance training was found to have positive effects on body fat, VO2peak, blood total antioxidant capacity, and muscle damage markers. Based on these results, the community should be encouraged to perform folk dance as a recreational physical activity, and public awareness should be raised about the health benefits of practising folk dances.

    Full Text Available Objective This study measured serum and follicular fluid (FF levels of biopterin, neopterin, vascular endothelial growth factor (VEGF, and macrophage colony-stimulating factor (M-CSF in patients receiving mild ovarian stimulation for oocyte retrieval. Patients and Methods Infertile patients who underwent ovarian stimulation were divided into the following: Group 1, no oocyte retrieval ( n = 12, and Group 2, retrieval of more than four oocytes ( n = 13. Median total gonadotropin dose in both groups was 150 IU. Biopterin and neopterin levels were measured using high-performance liquid chromatography. VEGF and M-CSF levels were measured by enzyme-linked immunosorbent assay. Results Compared to Group 2, serum and FF levels of neopterin and VEGF and serum levels of M-CSF were significantly increased, and serum and FF levels of biopterin were significantly decreased in Group 1 ( P < 0.05 each. Conclusion Biopterin and neopterin levels showed similar differences in FF and serum of patients with empty follicles. Decreased biopterin and increased neopterin in serum could predict poor oocyte retrieval.

    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.

    Inhibin B is a testicular peptide hormone that regulates FSH secretion in a negative feedback loop. In males serum levels of inhibin B are detectable throughout life with prominent changes in the first year of life and during puberty. Serum inhibin B is normally detectable throughout childhood...... normal or near-normal levels are seen in cryptorchidism and disorders with preserved Sertoli cell function in spite of absence of germ cells or impaired androgen biosynthesis or action. During puberty a developmental change in the regulation of serum inhibin B occurs. In contrast to childhood inhibin B...

    Full Text Available Introduction: High low-density lipoproteins (LDL cholesterol is one of the major risk factors for cardiovascular disease. In recent years, some evidence has been presented that periodontitis,an infectious inflammatory condition of the periodontium, is associated with an increased risk of cardiovascular disease. To further elucidate this association, we have studied the levels of LDL cholesterol, a known risk marker for cardiovascular disease, in a periodontally-diseased group. Methods: The levels of serum LDL cholesterol in 47 subjects with mild to severe (clinical attachment loss equal to or greater than 1 mm chronic generalized (at least 30% of teeth affected periodontitis with the mean age of 42.21 ± 1.46 years were measured and compared with those obtained from 42 age (39.83 ± 0.94 and sex matched controls. Both groups were free from systemic illnesses. Results: The mean serum LDL cholesterol in periodontitis patients was found to be signifi cantly higher (P < 0.001 as compared to that of the controls. The mean clinical attachment loss was positively correlated with serum LDL cholesterol (P < 0.01 and gingival index (P<0.05. The frequency of persons with pathologic values of LDL cholesterol was signifi cantly higher in periodontitis patients compared with that of the controls. Conclusions: These results showed that high serum LDL cholesterol may be associated with periodontitis in healthy people. However, it is unclear whether periodontitis causes an increase in the levels of serum LDL or an increased LDL is a risk factor for both periodontitis and cardiovascular disease. Keywords: Cardiovascular disease, LDL cholesterol, periodontitis.

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

    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

    Full Text Available Abstract    INTRODUCTION: Studies on the association between the plasma concentration of lipoprotein (a and coronary heart disease (CHD have reported conflicting findings.    METHOD AND MATERIALS: The objective of the present study was to evaluate the association between serum levels of lipoprotein (a and ischemic heart disease as well as other cardiovascular risk factors in a population-based study. Lipoprotein (a serum was measured in 142 patients with chronic stable angina undergoing clinically indicated coronary angiography. Lipid profile, fasting blood glucose, anthropometric and clinical parameters were analyzed.    RESULTS: Lipoprotein (a levels were significantly associated with coronary artery stenosis in men, but not in women. Also, an direct association between mean levels of lipoprotein (a and coronary artery stenosis in men younger than 55 years old and an inverse association in men older than 55 years old were observed.     CONCLUSION: Multivariate analysis revealed that lipoprotein (a was considered an independent predictor for severity of CAD in men, especially in younger ages.      Keywords: Lipoprotein (a, cardiovascular risk factors, Ischemic heart disease, coronary angiography.

    Statin therapy is associated with a slightly increased risk of developing diabetes mellitus and insulin resistance in patients without diabetes. Ezetimibe combined with statins may be considered for high-risk patients who do not achieve optimal low-density lipoprotein cholesterol lowering on statin monotherapy or who are statin intolerant. Changes in fasting serum glucose (FSG) levels during ezetimibe, ezetimibe/statin, and statin treatments were assessed using data pooled from clinical trials in hypercholesterolemic and heterozygous familial hypercholesterolemic patients, who were or were not receiving statin therapy. Study types included first-line trials in statin-naive/wash-out patients and second-line add-on and uptitration studies in patients on stable statin therapy. Similar analyses of FSG changes were performed separately for each study type in patients who were nondiabetic at baseline. Across all study types and treatments, mean FSG increases from baseline were small (0.5 to 3.7 mg/dl with ezetimibe/statin; 0.2 to 4.6 mg/dl with statins) and decreased over time; between-treatment differences (0.3 to 1.4 mg/dl) were nonsignificant for all comparisons. Proportions of patients with elevated FSG ≥126 mg/dl during therapy were low and similar for all treatments in the overall cohort (1.2% to 4.3%). Elevations were highest (3.3% to 25.7%) among patients with baseline factors characteristic of metabolic syndrome and prediabetes, including higher FSG, body mass index, and triglyceride levels, and numerically lower baseline high-density lipoprotein cholesterol; however, these factors were not related to FSG increases. Changes in low-density lipoprotein cholesterol, body mass index, high-density lipoprotein cholesterol, triglycerides, and apolipoprotein B were not significantly correlated with FSG increases. In conclusion, statin therapy was associated with small FSG increases, and the addition of ezetimibe did not further increase FSG levels beyond those of

    Low levels of serum high-density lipoprotein cholesterol (HDL-C) have been shown to be associated with increased risk of coronary heart disease (CHD). However, because this is usually observed in the context of other lipid abnormalities, it is not known whether isolated low serum HDL-C levels are an independent risk factor for CHD. We performed a large pooled analysis in Japan using data from nine cohorts with 41,206 participants aged 40-89 years who were free of cardiovascular disease at baseline. We divided participants into three groups: isolated low HDL-C, non-isolated low HDL-C, and normal HDL-C. Cohort-stratified Cox proportional hazards models were used to estimate multivariate-adjusted hazard ratios (HRs) for death due to CHD, ischemic stroke, and intracranial cerebral hemorrhage; during a 12.9-year follow-up, we observed 355, 286, and 138 deaths, respectively, in these groups. Non-isolated low HDL-C was significantly associated with increased risk of CHD compared with normal HDL-C (HR 1.37, 95 % confidence interval (CI) 1.04-1.80); however, isolated low HDL-C was not. Although isolated low HDL-C was significantly associated with decreased risk of CHD (HR 0.51, 95 % CI 0.29-0.89) in women, it was significantly associated with increased risk of intracranial cerebral hemorrhage in all participants (HR 1.62, 95 % CI 1.04-2.53) and in men (HR 2.00, 95 % CI 1.04-3.83). In conclusion, isolated low HDL-C levels are not associated with increased risk of CHD in Japan. CHD risk may, therefore, be more strongly affected by serum total cholesterol levels in this population.

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

    Full Text Available 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.

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

    Full Text Available Introduction: Lipoprotein (a is a particle rich in cholesterol in human plasma and it is known as an independent risk factor for coronary artery disease. In addition to genetic background, other factors such as diabetes affect the plasma concentration of this lipoprotein as a risk factor. The aim of this study was evaluation and comparison of plasma concentration of Lp(a in type II diabetics and non diabetic individuals. Material and Methods: The study population included 180 diabetic patients who had referred to the Diabetic Research center of Yazd and 180 non diabetic individuals who were matched according to age and sex with the patient group. Blood samples were collected from the study groups in fasting condition. Glycated hemoglobin, glucose, lipids and lipoproteins were measured by routine laboratory methods and Lp(a assay was carried out by electro immunodiffusion. Results were analyzed with the use of SPSS program. Statistical tests included variance analysis, t-test for comparing lipids and lipoproteins, U-test for comparing Lp(a in the two groups and Pearson Correlation for determining of the variables with Lp(a. Results: Mean plasma concentratin of Lp(a in diabetic patients (Mean + SD 41.98+ 34.63 mg/dl was significantly higher than that of the control group (26.6 + 20.2 mg/dl (P<0.001. Mean concentration of cholesterol, triglyceride and LDL cholesterol in the patient group was higher but mean HDL cholesterol in control group was higher than patient group. However, no significant correlation was found between Lp(a and other variables in the patient and control groups. Conclusion: Plasma concentration of Lp(a in Diabetes Mellitus is increased independently. In diabetic patients, the risk of coronary artery disease may increase with increase in Lp(a.

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

    Full Text Available Background. Psoriasis is a chronic inflammatory skin disease characterized by an accelerated turnover of epidermal cells and an incomplete differentiation in epidermis with lesion. However, the exact etiology of psoriasis is unknown. Abnormalities in essential fatty acid metabolism, free radical generation, lipid peroxidation, and release of lymphokines have been proposed. Objective. Our purpose was to evaluate the plasma lipids and oxidized low-density lipoprotein accumulation in psoriatic skin lesion in order to ascertain the possible participation of oxidative stress and oxidative modification of lipids in pathogenesis of psoriasis. Methods. The study group included 84 patients with psoriasis, and 40 sex- and age-matched healthy volunteers. Blood lipid profile was determined. Psoriatic and nonlesional skin samples of psoriatic patients were evaluated for the presence of oxidized low-density lipoprotein by using an immune-fluorescent staining method. Results. The mean levels of lipids (total cholesterol, triglyceride, and LDL cholesterol in patients with psoriasis were found to be significantly higher than those of healthy subjects. Psoriatic skins were shown positive oxidized low-density lipoprotein staining. There was no staining in nonlesional skin samples of the same individuals. Conclusion. Lipid peroxidation mediated by free radicals is believed to be one of the important causes of cell membrane destruction and cell damage. This study shows for the first time the accumulation of oxidized low-density lipoprotein in psoriatic skin lesion. We believe that accumulation of ox-LDL in psoriatic skin may have an important role in the immune-inflammatory events that result in progressive skin damage.

    Full Text Available Objective: In this study, it was aimed to evaluate the ef­fects of short-term intensive exercise on liver enzymes and serum lipid levels with kick boxing athletes. Methods: 23 voluntary athletes who were between the ages of 15-46 and who engaged in kick–boxing have tak­en place this study. Athletes were made to do 45 minutes of warming-up, breathing, and stretching and 50 minutes of technical and tactical practices and then they were made to do a training match, which is equal to a 2 min­utes 3 circuits (1 minute rest kick-box match. In venous blood samples which were taken from athletes before and after training, aspartate aminotransferase (AST, alanine aminotransferase (ALT, alkaline phosphatase (ALP and gamma glutamine transpeptidase (GGT, enzyme activity and total cholesterol, high-density lipoprotein-cholesterol (HDL-C, low density lipoprotein-cholesterol (LDL-C and triglycerides serum levels were analyzed via spectropho­tometric method in Beckman Coulter AU 5800 auto ana­lyzer. Body composition measurements of athletes were made with Tanita TBF 300 brand device, which works with bio-impedance analysis (BIA system. Results: As a result of our study, statistically increases in serum ALT, AST, ALP and GGT enzyme activities and in serum total cholesterol, HDL-C and LDL-C levels were detected following short-term intensive exercise, but no significant difference was observed in TG levels after in­tensive exercise. Conclusion: The blows to the abdomen during kickbox­ing sports competitions result in increased liver enzymes and increased serum lipids may occur to meet energy de­mand of the body during exercise.

    IL-10 expression limits inflammation and restricts the size of CNS damage from stroke. In this study, we examined the correlation between cerebral infarction (CI) and serum levels of interleukin-10 (IL-10) using a combination of case-control study and meta-analysis of published data, with an aim of understanding the relevance of serum IL-10 levels to CI development. This study enrolled a total of 169 CI patients admitted to the Second Hospital of Hebei Medical University between May 2011 and November 2014. During the same period, a group of 145 individuals were recruited at the same hospital as healthy controls after thorough physical examination. Serum IL-10 levels were measured by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 (IBM, 2010, Chicago, IL, USA) and Comprehensive Meta-Analysis 2.0 (CMA 2.0) software were used for data analysis. Serum levels of IL-10 (pg/mL) were significantly lower in CI patients when compared to healthy controls (15.36 ± 3.21 vs. 21.64 ± 5.17, t = 13.12, P 0.05). Logistic regression analysis indicated that, with the exception of triglyceride (TG) and uric acid (UA) levels (both P > 0.05), the other seven parameters, including fasting blood glucose (FPG), total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), creatinine (Cr), systolic blood pressure (SBP), and diastolic blood pressure (DBP), strongly correlated with CI development (all P analysis of pooled data from nine case-control studies revealed an inverse correlation between the serum IL-10 levels and CI (SMD = 1.797, 95% CI 0.785~2.810, P = 0.001). Subgroup analysis based on country showed that low serum levels of IL-10 may be the major risk factor for CI in Croatia (SMD = 2.961, 95% CI 2.480~3.443, P analysis based on ethnicity showed that IL-10 serum levels and CI displayed negative relationship in Asians (SMD = 2.522, 95% CI 0.468~4.576, P = 0.016) but not in Caucasians (P > 0.05). Our study provided convincing evidence that the patients

    2013-04-01

    Full Text Available Objective: Adipokines are signaling and mediator proteins secreted from adipose tissue. A novel adipokine, visfatin, was reported as a protein which was mainly expressed in visceral adipose tissue. Controversial results have been shown regarding the changes of adipokines following weight reduction. So we investigated the effects of weight reduction on serum concentrations of adiponectin and visfatin in morbidly obese subjects. Methods: 35 severely obese patients (26 females and 9 males, aged 15-58 years, were studied. Anthropometric parameters and biochemical parameters as well as adiponectin and visfatin were analyzed before and 6 weeks after weight reduction. Results: Anthropometric indices decreased significantly. Blood levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride were reduced significantly. The reduction of visfatin and the elevation of adiponectin were significant as well. However, other parameters like fasting glucose and insulin did not change. Moreover, we could not find any significant correlation between the change of serum visfatin and that of adiponectin. Conclusions: 6-week weight reduction after bariatric surgery resulted in decreased serum visfatin and increased adiponectin levels. However, we cannot find any significant correlation between changes of adiponectin, visfatin, BMI, waist circumference, and insulin resistance. Further studies with different design are suggested to clarify these associations.

We tested in a cohort of 3,333 males aged 53 to 74 years the hypothesis that a low serum selenium would be associated with an increased risk of lung cancer mortality.During 16 years, 167 subjects(5.......1%) died from lung cancer; 48 males (5.0%) among males with low serum selenium, 0.4-1.0 μmol·l(-1), n=965, 57 males (5.1%) among males with medium serum selenium, 1.1-1.2 μmol·l(-1), n=1,141, and 62 males (5.1%) among males with high serum selenium, 1.3-3.0 μmol·l(-1), n=1,227. After adjustment for age...... (chronic bronchitis and peak flow), referencing the lowest level of serum selenium HRs were 1.17(0.79-1.75), and 1.43(0.96-2.14), respectively. Among heavy smokers a high serum selenium was associated with a significantly increased risk of lung cancer mortality after taking into account all potential...

    Objectives: The aim of present study was to investigate serum homocysteine levels in apparently healthy vegetarians and ominvores in Mithi, district Tharparker, Sindh, Pakistan. Methods: This study was conducted in the Department of Biochemistry, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Center (JPMC), Karachi and blood samples were collected from Mithi, district Tharparker, Sindh, Pakistan, in 2012. One hundred vegetarian and one hundred omnivores (age ranging from 20-40 years) were enrolled for this study. Serum homocysteine levels were measured by the chemiluminescence enzyme immunoassay method. Results: Serum homocysteine (Hcy) level was considerably higher (p15µmol/L compared to omnivores 6%, (p15µmol/L serum Hcy level in vegetarian group and 6.9% male and 3.5% females had >15µmol/L serum Hcy level in omnivores group, but the difference was not significant in any group. Conclusion: Vegetarians are more prone to develop hyperhomocysteinemia, so they are at high risk to develop cardiovascular disease. PMID:25878628

    Patient with arterial hypertension and no definable cause are said to have essential, primary or idiopathic hypertension. A total of 100 patients suffering from essential hypertension and 100 control subjects with almost same mean age and sex distribution were enrolled in this study. Levels of serum uric acid, total cholesterol, TG, and HDL-c were determined by enzymatic colorimetric method. Serum LDL-c and VLDL-c was calculated by using Friedewald and Wilson's formulae. The study was aimed to find out the levels of serum uric acid and lipid profile in patients with essential hypertension and to compare them with levels of normal healthy individuals. Results show increased level of serum uric acid and lipid parameters except for HDL-c, which was significantly, decreased in patients with essential hypertension as compared to the control subjects. Variations in aforementioned parameters were also observed on comparing the obese and the non-obese patients. It can be concluded from the present study that the essential hypertension is associated with abnormalities in the levels of serum uric acid and lipid profile. (author)

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

    Serum cholesterol levels and dietary habits were surveyed in 27 male and 34 female Seventh-day Adventist. All subjects studied were lacto-ovo-vegetarians and a few consumed some meat products. Their serum cholesterol levels, significantly lower than those of the United States general population, showed no sex difference but increased with age and were higher in overweight males. Their levels, however, were much higher than those of true vegetarians which was most likely attributable to their consumption, even though to a limited acount, of dairy foods.

    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. The serum IL-6 level had a significant correlations with CPR, Ferritin, TIBC, WBC and their serum IL-6 level was significantly higher in patients with hypertension, but no significant correlation was observed between other parameters and IL-6

    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 Oxidized LDL (ox-LDL lipoproteins are proposed as important modified particles triggering pro-inflammatory events through receptor-mediated pathways. We evaluated the circulating ox-LDL level on the concept that the chronic immune events may affect ox-LDL clearance as the vessel stenosis develops in coronary arteries. One hundred sixty five subjects underwent coronary angiography and then, subdivided into four subgroups controls (n=85; SVD, 2VD and 3VD (n=80. The serum ox-LDL level and other biochemical parameters were measured using ELISA method and routine laboratory techniques, respectively. The serum ox-LDL level in the control group (4.81±1.41 mU/mg was significantly higher than patients (4.28±1.73 mU/mg, P<0.05. The ox-LDL/LDL ratio was conversely reduced with the extent of stenosis as compared with the controls (P<0.05. Furthermore, no difference was observed in the ox-LDL/LDL ratio between the 2VD and 3VD patients. We suggested the atherosclerosis process increases the total clearing capacities of the circulating ox-LDL particles.

    Full Text Available Introduction. Coronary artery disease (CAD is one of the most prevalent disease in human population that has high prevalence and mortality in lsfahan (Iran. As positive family history and changes in serum lipids and lipoproteins are risk factors of these diseases, and also studies have showed the relationship between serum vitamin D and CAD, we studied serum level of lipids, lipoproteins and vitamin D in high risk children compared with control group, and the relation between serum vitamin D and other factors. Methods. This case-control study was done on 44 subjects (25 boys, 19 girls aged 2-18 years old with positive CAD family history as case group and also 44 persons with negative CAD family history as control group with the same age groups. The subjects were selected by convenience sampling method. Children who consumed antiepilepthic drugs as phenytoin or phenobarbital and those who had positive family histroy for renal stone were excluded for variable vitamin D levels due to drug interaction and genetic susceptibility, respectively. All subjects were invited to Isfahan Cardiovascular Research Center. Using a questionnaire, information on personal characteristics, CVD family history and ... were obtained. A fasting (12-14 hr blood sample was drawn from each one. Serum APOA1, APO B100 and vitamin Dwere measured by radioimmunoassay and serum lipids by ELAN 2000 autoanalyzer. Statistical analysis was done by SPSS. The level of serum APOA1, APO B100 and vitamin D were compared between two groups by independent t test and the relation of the mentioned apolipoproteins with vitamin D was studied using multiple linear regression. Results. Serum vitamin D was significantly lower in case group (P < 0.045. Among studied factors, only triglyceride was significantly higher in control group (P < 0.0001 and also no significant relaitonship was observed between serum APO A1, APO B100 and vitamin D. Sex comparision in case group showed those mean 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.

    It was reported that Vitamin D deficiency was associated with a greater risk of cardiometabolic diseases, obesity, impaired glucose tolerance and diabetes mellitus type 2, arterial hypertension, and dyslipidemia. Apelin is an adipocytokine suspected to have a role in skeletal muscle glucose utilization and glycemic regulation which may be a promising treatment modality for diabetes. It was recently reported that increased mean platelet volume (MPV) was emerging as an independent risk factor for thromboembolism, stroke, and myocardial infarction. In patients with diabetes, MPV was higher compared with the normal glycemic controls; in addition, it has been proposed that an increase in MPV may play a role in the micro- and macro-vascular complications related to diabetes. We postulated that deficiency in Vitamin D levels might be associated with higher MPV and lower serum apelin levels leading a further increase in insulin resistance in diabetic patients. So, we aimed to investigate Vitamin D levels, MPV and serum apelin levels in diabetic patients and their correlations between each other. This is a cross-sectional study design. Seventy-eight patients with Diabetes Mellitus type 2, admitted to our outpatient clinic of internal medicine department at Bezmialem Vakif University, were included in our study. Forty-one patients were female; 37 patients were male. Serum apelin levels, fasting glucose levels, urea, creatinine, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting serum insulin level, HbA1c, free T3, free T4, TSH, vitamin D (25-OH Vitamin D) and complete blood counts were analyzed in all subjects. Each sex was analyzed separately. We found that a positive correlation existed between serum apelin levels and BMI in female patients. (r: 0.380, P: 0.014) There was also a significant positive correlation between MPV and HbA1c and fasting glucose levels and a negative correlation

  15. Serum Albumin Levels and Economic Status in Japanese Older Adults.

    Directory of Open Access Journals (Sweden)

    Asami Ota

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

    Full Text Available Background: The etiology of multiple sclerosis (MS, a chronic demyelinative disease-is unknown. The damage of blood–brain barrier (BBB vasculature is a characteristic of MS and Homocystein (Hcy can damage BBB, then increase in total Hcy may be important in MS pathogenesis. The aim of this study was to compare the serum level of total Hcy in MS patients with control group. Methods: In a case control study, serum level of total Hcy measured in 35 MS patient and compared with 30 healthy matched controls. All patients had definitive MS according to Poser criteria, without history of myocardial infarction, stroke, neuropathy, transient ischemic attack, homocystinuria or renal failure. Results: The serum concentration of total homocystein was significantly higher in multiple sclerosis patients than healthy controls. The mean total Hcy level was 17.92± 6.9 mmol/lit in cases and 14.6±2.92 mmol/lit in controls (P=0.013. Conclusion: Serum total Homocystein may have a role in MS pathogenesis and reduction of it should be studied moreover. Key words: Multiple Sclerosis, Homocystein, Serum level

    2008-09-01

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

    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

    1987-01-01

    The tumor marker CA-125 is an embrional glycoprotein detectable in tissues derived from celomatic epitelium. Serum Ca-125 was determined by RIA in 66 patients with various ovarian pathologies (16 malignant at stage III-IV and 50 benign). Six patients with ovarian carcinoma were monitored during the first week after surgery and chemiotherapy for a total of 150 days of treatment. It has been observed that CA-125 serum level is consistently above the normal range (>35 U/ml) in all malignant diseases. In benign pathology, levels above the normal were found to be represented almost exclusively by ovarian endometriosis. Furthermore, the results demonstrate that chemiotherapy alone is capable of lowering CA-125 serum levels. This tumor marker may be of great advantage in diagnosis and follow-up of ovarian malignancy

    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.

    Refeeding syndrome is a life-threatening condition occurring in severely malnourished patients after initiating feeding. Severe hypophosphatemia with reduced adenosine triphosphate production has been implicated, but little data are available regarding electrolyte abnormalities. In this case, we report electrocardiographic changes consistent with hyperkalemia during potassium replacement after a serum level increase from 1.9 to 2.9 mEq/L. This was reversed by lowering serum potassium back to 2.0 mEq/L. In conclusion, the patient with prolonged malnutrition became adapted to low potassium levels and developed potassium toxicity with replacement. Copyright © 2015 Elsevier Inc. All rights reserved.

    Although water-soluble vitamins such as thiamine are lost during dialysis session, serum thiamine level tended to restore spontaneously during the hospitalization (25.47±10.07 vs. 27.44±11.37, pre HD value, p=0.09. A three months-follow up measurement after initiation of HD, which is now in progress (so far n=3, revealed increase of serum thiamine level in all patients (35.33±7.37 ng/ml. It may reflect the improvement of nutritional status after the initiation of HD, and suggests the loss of thiamine by HD procedure can be covered.

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

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

    Serum carnitine is decreased in recurrent pulmonary infections. We aimed to evaluate serum carnitine levels in asthmatic children. Study group consisted of children with stable asthma and those with acute asthma attacks, while control group included healthy children. Attack severity was determined by the pulmonary score system. Total and free carnitine levels were studied in one blood sample from the control group and stable asthmatics and in two samples from children with acute asthma exacerbation during and after the attack. All the 40 patients in the study group had moderate asthma including 30 with acute attack (13 mild and 17 moderate) and 10 with stable asthma. Carnitine levels were significantly lower in acute attack asthmatics than in the stable asthmatics and controls, while there was no significant difference between the latter two groups. Carnitine levels were not different between asthmatics with mild and moderate attack, and were similar during and after an acute attack. Serum carnitine levels decrease in children with moderate asthma during exacerbation of asthma and shortly thereafter. Further studies are needed to evaluate the effect of carnitine treatment on serum carnitine level.

    Full Text Available Background. Few studies have shown that self-reported secondhand smoke exposure in never smokers is associated with high blood pressure. However, there are no studies investigating the relationship between secondhand smoke exposure, measured objectively by serum cotinine levels, and high blood pressure in never smokers. Methods. We examined never smokers (n=2027 from the National Health and Nutrition Examination Survey 2005–2008. Our exposure of interest was the secondhand smoke exposure estimated by serum cotinine level and our outcome was prehypertension (n=734, defined as a systolic blood pressure of 120–139 mmHg or diastolic blood pressure of 80–89 mmHg. Results. We found that, in never smokers, serum cotinine levels were positively associated with prehypertension. Compared to those with cotinine levels in the lowest quartile (≤0.024 ng/mL, the multivariable odds ratio (95% confidence interval of prehypertension among those with cotinine levels in the highest quartile (≥0.224 ng/mL was 1.45(1.00, 2.11; P trend =0.0451. In subsequent subgroup analyses, the positive association was found to be stronger among men, non-Whites, and non-obese subjects. Conclusion. Higher secondhand smoke exposure measured objectively by serum cotinine levels was found to be associated with prehypertension in certain subgroups of a representative sample of the US population.

  10. Higher Lipoprotein (a Levels Are Associated with Better Pulmonary Function in Community-Dwelling Older People - Data from the Berlin Aging Study II.

    Full Text Available Reduced pulmonary function and elevated serum cholesterol levels are recognized risk factors for cardiovascular disease. Currently, there is some controversy concerning relationships between cholesterol, LDL-cholesterol, HDL-cholesterol, serum triglycerides and lung function. However, most previous studies compared patients suffering from chronic obstructive pulmonary disease (COPD with healthy controls, and only a small number examined this relationship in population-based cohorts. Moreover, lipoprotein a [Lp(a], another lipid parameter independently associated with cardiovascular diseases, appears not to have been addressed at all in studies of lung function at the population level. Here, we determined relationships between lung function and several lipid parameters including Lp(a in 606 older community-dwelling participants (55.1% women, 68±4 years old from the Berlin Aging Study II (BASE-II. We found a significantly lower forced expiration volume in 1 second (FEV1 in men with low Lp(a concentrations (t-test. This finding was further substantiated by linear regression models adjusting for known covariates, showing that these associations are statistically significant in both men and women. According to the highest adjusted model, men and women with Lp(a levels below the 20th percentile had 217.3ml and 124.2ml less FEV1 and 239.0ml and 135.2ml less FVC, respectively, compared to participants with higher Lp(a levels. The adjusted models also suggest that the known strong correlation between pro-inflammatory parameters and lung function has only a marginal impact on the Lp(a-pulmonary function association. Our results do not support the hypothesis that higher Lp(a levels are responsible for the increased CVD risk in people with reduced lung function, at least not in the group of community-dwelling older people studied here.

    Full Text Available We studied the effect of three programs, diet restriction (D, individualized exercise training (E at the maximal lipid oxidation point (LIPOXmax and diet combined with exercise (D+E, on body mass, plasma lipoprotein and adiponectin levels in obese girls. Eighteen obese adolescents girls aged 12-14 years were studied. A longitudinal intervention was carried out, consisting of a two-month diet (D; -500 kcal·day-1, of individualized exercise (E; 4 days/week, 90 min·day-1 and of diet combined with exercise (D+E. Body mass, body mass index (BMI, body fat mass, waist circumference, substrate crossover point, LIPOXmax point, homeostasis model assessment (HOMA-IR index, fasting levels of lipids and circulatory adiponectin, were measured in all subjects before and after the program. In subjects of the D+E group, body mass, BMI, body fat mass, waist circumference, HOMA-IR, low-density lipoprotein cholesterol (LDL-C and total cholesterol / high-density lipoprotein cholesterol (TC/HDL-C ratio were significantly lower, and HDL-C and adiponectin were higher after the program than that of subjects in the D or E groups. Diet/exercise improved the ability to oxidize lipids during exercise (crossover point: + 18.5 ± 3.4 of % Wmax; p < 0.01 and fat oxidation rate at LIPOXmax: + 89.7 ± 19.7 mg·min-1; p < 0.01. In the D+E group, significant correlations were found between changes in body mass and adiponectin and between changes in the TC/HDL-C ratio and LIPOXmax. These findings show that the combined program of diet restriction and individualized exercise training at the LIPOXmax point is necessary to simultaneously improve body mass loss, adiponectin levels, as well as metabolic parameters, in obese girls

    Full Text Available Abstract Background Chronic kidney disease (CKD is a newly recognized high-risk condition for cardiovascular disease (CVD, and previous studies reported the changes in inflammation and oxidative stress in advanced stages of CKD. We compared the levels of serum biomarkers for inflammation and oxidative stress between subjects with normal and mildly reduced glomerular filtration rate (GFR. Methods The subjects were 182 participants of a health check-up program including those with normal (≥ 90 mL/min/1.73 m2, N = 79 and mildly reduced eGFR (60-89 mL/min/1.73 m2, N = 103 which was calculated based on serum creatinine, age and sex. We excluded those with reduced eGFR 2. No one had proteinuria. We measured serum levels of C-reactive protein (CRP and thioredoxin (TRX as the markers of inflammation and oxidative stress, respectively. Results As compared with subjects with normal eGFR, those with mildly reduced eGFR had increased levels of both CRP and TRX. Also, eGFR was inversely correlated with these biomarkers. The associations of eGFR with these biomarkers remained significant after adjustment for age and sex. When adjustment was done for eight possible confounders, CRP showed significant association with systolic blood pressure, high density lipoprotein cholesterol (HDL-C and non-HDL-C, whereas TRX was associated with sex significantly, and with eGFR and systolic blood pressure at borderline significance. Conclusions We showed the increased levels of CRP and TRX in subjects with mildly reduced eGFR. The eGFR-CRP link and the eGFR-TRX link appeared to be mediated, at least partly, by the alterations in blood pressure and plasma lipids in these subjects.

    Objective: To study the clinical meanings of changes of serum C-peptide levels and insulin/C-peptide ratio. Methods: Serum insulin and C-peptide levels were determined with RIA in 171 patients with DM-2 of all ages (31-50, n= 50, 51-60, n=60, over 60, n=61) and 50 patients with renal insufficiency. The insulin/C-peptide ratio were calculated. Results: The serum C-peptide and insulin levels in patients with renal insufficiency were significantly higher than those in diabetics of all age groups and the insulin/C-peptide ratio were significantly lower than those in diabetics (P 0.05), but the serum C-peptide levels increased as the age of patients increased with decrease of insulin/C-peptide ratio (P<0.01). Conclusion: Abnormal changes of C-peptide levels and insulin/C-peptide ratio in diabetics (the age-factor corrected) might reflect renal dysfunction. (authors)

    The causes of late-onset Alzheimer disease (AD) are not yet understood but likely include a combination of genetic, environmental, and lifestyle factors. Limited epidemiological studies suggest that occupational pesticide exposures are associated with AD. Previously, we reported that serum levels of dichlorodiphenyldichloroethylene (DDE), the metabolite of the pesticide dichlorodiphenyltrichloroethane (DDT), were elevated in a small number of patients with AD (n=20). To evaluate the association between serum levels of DDE and AD and whether the apolipoprotein E (APOE) genotype modifies the association. A case-control study consisting of existing samples from patients with AD and control participants from the Emory University Alzheimer's Disease Research Center and the University of Texas Southwestern Medical School's Alzheimer's Disease Center. Serum levels of DDE were measured in 79 control and 86 AD cases. Serum DDE levels, AD diagnosis, severity of AD measured by the Mini-Mental State Examination score, and interaction with APOE4 status. Levels of DDE were 3.8-fold higher in the serum of those with AD (mean [SEM], 2.64 [0.35] ng/mg cholesterol) when compared with control participants (mean [SEM], 0.69 [0.1] ng/mg cholesterol; P risk for AD (95% CI, 2.54-5.82; P risk for AD and carriers of an APOE4 ε4 allele may be more susceptible to the effects of DDE. Both DDT and DDE increase amyloid precursor protein levels, providing mechanistic plausibility for the association of DDE exposure with AD. Identifying people who have elevated levels of DDE and carry an APOE ε4 allele may lead to early identification of some cases of AD.

    Full Text Available Studies have shown that estrogen replacement therapy and estrogen plus progestin replacement therapy alter serum levels of total, LDL and HDL cholesterol levels. However, HDL cholesterol levels in women vary considerably in response to hormone replacement therapy (HRT. A significant portion of the variability of these levels has been attributed to genetic factors. Therefore, we investigated the influence of estrogen receptor-alpha (ESR1 gene polymorphisms on HDL levels in response to postmenopausal HRT. We performed a prospective cohort study on 54 postmenopausal women who had not used HRT before the study and had no significant general medical illness. HRT consisted of conjugated equine estrogen and medroxyprogesterone acetate continuously for 1 year. The lipoprotein levels were measured from blood samples taken before the start of therapy and after 1 year of HRT. ESR1 polymorphism (MspI C>T, HaeIII C>T, PvuII C>T, and XbaI A>G frequencies were assayed by restriction fragment length polymorphism. A general linear model was used to describe the relationships between HDL levels and genotypes after adjusting for age. A significant increase in HDL levels was observed after HRT (P = 0.029. Women with the ESR1 PvuII TT genotype showed a statistically significant increase in HDL levels after HRT (P = 0.032. No association was found between other ESR1 polymorphisms and HDL levels. According to our results, the ESR1 PvuII TT genotype was associated with increased levels of HDL after 1 year of HRT.

    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)

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

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

We 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.

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

    Full Text Available ObjectiveInflammation plays a central role in the pathogenesis of metabolic syndrome (MetS. Cyclophilin B (CypB can be constitutively secreted in response to inflammatory stimuli and oxidative stress, participating in tissue or systemic inflammation. We investigated the relationship between CypB and MetS in both humans and mice.MethodsSerum CypB levels were determined in 211 subjects with MetS and 292 subjects without MetS (non-MetS (133 healthy controls and 159 high-risk subjects with one to two MetS components. Additionally, CypB expression in metabolic organs was examined in mice fed with high-fat diet (HFD and genetically obese (ob/ob mice.ResultsSerum CypB level was significantly higher in MetS subjects compared with both groups of non-MetS subjects (193.80 ± 83.22 vs. 168.38 ± 65.01 vs. 124.26 ± 47.83 ng/mL, P < 0.001. Particularly, serum CypB level was significantly higher in subjects with hypertension, central obesity, diabetes mellitus or hyperglycemia, elevated levels of triglycerides, or reduced levels of high-density lipoprotein than in those without. Moreover, CypB was positively associated with the number of MetS components (r = 0.404, P < 0.001, indicating that a higher serum CypB level reflected more severe MetS. Multivariate regression revealed that a one SD increase in CypB was associated with an odds ratio of 1.506 (1.080–2.101, P = 0.016 for MetS prevalence after adjusting for age, gender, conventional risk factors, and medication. Stratified analyses by age and gender demonstrated that subjects >60 years old with higher CypB levels were more likely to have MetS, and the risk for MetS was higher and more significant in women compared with men. Additionally, CypB expression levels were lower at baseline and dramatically enhanced in metabolic organs (such as the liver and visceral and subcutaneous adipose tissue from HFD-induced obese mice and ob/ob mice.ConclusionIncreased CypB levels were

    Full Text Available BACKGROUND: The detrimental effects of partially hydrogenated vegetable oils (PHVOs on apolipoproteins have been reported from several parts of the world. However, little data is available in this regard from the understudied region of the Middle East. The present study therefore tried to evaluate the association between type of vegetable oils and serum lipids and apolipoprotein levels among Iranians. METHODS: In this cross-sectional study, data from 1772 people (795 men and 977 women aged 19-81 years, who were selected with multistage cluster random sampling method from three cities of Isfahan, Najaf Abad and Arak in "Isfahan Healthy Heart Program" (IHHP, was used. To assess participants' usual dietary intakes, a validated food frequency questionnaire was used. Hydrogenated vegetable oil (commonly consumed for cooking in Iran and margarine were considered as the category of PHVOs. Soy, sunflower, corn, olive and canola oils were considered as non-HVOs. After an overnight fasting, serum cholesterol (total, low density lipoprotein (LDL and high density lipoprotein (HDL cholesterol and triglyceride as well as apolipoproteins A and B were measured using standard methods. RESULTS: Participants with the highest intakes of non-HVOs and PHVOs were younger and had lower weight than those with lowest intakes. High consumption of non-HVOs and PHVOs was associated with lower intakes of energy, carbohydrate, dietary fiber, and higher intakes of fruits, vegetables, meat, milk and grains. No overall significant differences were found in serum lipids and apolipoprotein levels across the quartiles of non-HVOs and PHVOs after controlling for potential confounding. CONCLUSION: We did not find any significant associations between hydrogenated or non-hydrogenated vegetable oil and serum lipid and apolipoprotein levels. Thus, further studies are needed in this region to explore this association. Keywords: Vegetable Oils, Cardiovascular Risk Factors, Lipids

    Insulin resistance (IR) was recognized as a risk factor for the occurrence of abortion in patients with polycystic ovary syndrome (PCOS). Chemerin was an adipokine which could induce IR and associated with reproductive process closely. However, few studies have inquired the relativity between chemerin and the occurrence of abortion in patients with PCOS. The aim of this study was to evaluate the relationship between serum chemerin and the occurrence of abortion in women with PCOS. We recruited 198 women with PCOS to participate in our study. On the third day of menstrual cycle or a random day in women with amenorrhea, we obtained their venous blood and measured the fasting insulin, fasting plasma glucose, total cholesterol, high density lipoprotein cholesterol, triglyceride, chemerin, and hormones including FSH, E2, P, PRL, LH, and T. Additionally, BMI, HOMA-IR and LH/FSH of each subject were calculated. Finally, 58 of them were included in the study, in which 30 of them had normal pregnancy and the other 28 had an early miscarriage. We compared the biochemical characteristics between the normal pregnancy group and abortion group by independent-samples t test. In our study, those with a normal pregnancy had a lower level of BMI, FINs, HOMA-IR, and chemerin compared to abortion patients (p PCOS patients (p PCOS. Thus, serum chemerin may serve as a biomarker to identify pregnant women with PCOS who are at particular risk for later abortion, and who may benefit from prevention strategies.

    Aluminium is produced from the mineral bauxite. Occupational exposure is reported during the industrial processing of aluminium and is associated with pulmonary and neurotoxicity. However, data on exposure and toxicity of workers in the open bauxite mining industry do not exist. Therefore, a study was performed to explore aluminium exposure in employees involved in this bauxite mining process in a Surinam mine. A group of workers occupationally exposed to aluminium in an open bauxite mine were compared with a group of nonexposed wood processors. Serum aluminium was analyzed using atomic absorption spectrometry Data from the clinical chemistry of the blood and a questionnaire were used to explore determinants for aluminium exposure. No significant difference between serum aluminium in the exposed (4.4 +/- 2.0 micrograms/L, n = 27) and control group (5.1 +/- 1.5 micrograms/L, n = 27) was detected. For the serum concentration of the clinical chemical variables (calcium, citrate, and creatinine), a statistically significant difference was computed (p < or = 0.02) between the exposed and control group. All levels were slightly higher in the exposed group; no statistically significant correlations with serum aluminium were found. In this study, serum aluminium values were in the normal range, no significant difference between the groups could be detected despite long-term occupational exposure.

    To study the changes in concentrations of serum hyaluronic acid in uncomplicated human pregnancies. We determined the concentrations of serum hyaluronic acid, using a specific enzyme-linked immunosorbent assay, in 70 nonpregnant women, 250 women during their pregnancies, and 68 women at the time of parturition. Results were analyzed for statistical significance with Scheffé test for multiple comparisons. During pregnancy, mean (+/- standard deviation) serum hyaluronic acid levels were 11.4 +/- 4.5, 13.6 +/- 2.8, 20.6 +/- 1.5, and 46.9 +/- 7.9 ng/mL at 5-14 (n = 47), 15-26 (n = 46), 27-37 (n = 58), and 38-40 (n = 99) weeks' gestation, respectively. Pregnant women in labor (n = 68) had significantly higher levels (100.4 +/- 11.3 ng/mL) than did women at term but not in labor (P hyaluronic acid concentrations increase as pregnancy progresses and serum levels increase significantly at term. Hyaluronic acid may be associated with cervical ripening during parturition.

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

    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.

    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)

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

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

    Cholesterol homeostasis is dependent upon the sterol regulatory element binding protein 2 (SREBP-2) regulatory system and the functioning of plasma proprotein convertase subtilisin/kexin type 9 (PCSK9). Many studies have also reported that low density lipoprotein receptor (LDLR) levels in cellular membranes are related to the functioning of these proteins. The aim of this study was to investigate the association of lipid profiles with circulating PCSK9 protein values and SREBP-2 expression levels in normal subjects. The study involved 120 randomly chosen healthy subjects. Their lipid profiles were measured using routine laboratory techniques, and the plasma PCSK9 protein and SREBP-2 expression levels were determined by ELISA and real time quantitative PCR methods, respectively. A statistical analysis was carried out using a statistical software package. Linear regression analyses showed a significant correlation between total cholesterol and PCSK9 (3.54 ± 1.31 ng/mL), as well as between total cholesterol and SREBP-2 (0.1-35.38) (p = 0.002 and p = 0.02, respectively). Furthermore, multiple regression analyses showed strict correlations between PCSK9 and cholesterol-related parameters especially the total cholesterol/HDL-C ratio (β = 3.53, p = 0.001). There was no significant correlation between circulating PCSK9 and SREBP-2 expression levels (r = 1.2, p = 0.3). The study results revealed that serum cholesterol-related parameters are strictly associated with plasma PCSK9 values, suggesting that PCSK9 function has a greater effect on serum total cholesterol levels than SREBP-2 expression does. Furthermore, the total cholesterol/HDL-C ratio was a better indicator for evaluating PCSK9 level than total cholesterol.

    Low-density lipoprotein (LDL) oxidation is an important event in atherosclerosis development. The relationship between oxidized LDL (oxLDL) autoantibodies and coronary artery disease (CAD) remains controversial. IgM and IgG autoantibodies to oxLDL were measured in twenty patients undergoing clinically indicated coronary angiography, and in ten young healthy volunteers from the Center of Molecular Immunology. The levels of IgM autoantibodies to oxLDL did not differ between no CAD patients and healthy subjects, but the levels of IgM autoantibodies to oxLDL of these two groups were higher compared with the one of CAD patient group. Our results, although preliminary, supports the hypothesis that this kind of Abs might be inversely associated with the presence of atherosclerosis

    This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

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

    During the past three decades, the incidence of hepatocellular carcinoma in the United States has tripled. The neuroendocrine character has been observed in some tumor cells within some hepatocellular carcinoma nodules and elevated serum chromogranin A also been reported in patients with hepatocellular carcinoma. The aim of this work was to investigate the role of serum concentration of chromogranin A in patients with hepatocellular carcinoma at different stages. The study population consisted of 96 patients (63 males and 33 females age range 52-84) at their first hospital admission for hepatocellular carcinoma. The control group consisted of 35 volunteers (20 males and 15 females age range 50-80). The hepatocellular carcinoma patients were stratified according the Barcelona-Clinic Liver Cancer classification. Venous blood samples were collected before treatment from each patients before surgery, centrifuged to obtain serum samples and stored at -80° C until assayed. The chromogranin A serum levels were elevated (> 100 ng/ml) in 72/96 patients with hepatocellular carcinoma. The serum levels of chromogranin A were significantly correlated (p<0.05) with alpha-fetoprotein. In comparison with controls, the hepatocellular carcinoma patients showed a significant increase (p<0.001) vs controls. The chromogranin A levels in the Barcelona staging of hepatocellular carcinoma was higher in stage D compared to stage C (p<0.01), to stage B (p<0.001), and to stage A (p<0.001). Molecular markers, such as chromogranin A, could be very useful tools for hepatocellular carcinoma diagnosis. However the molecular classification should be incorporated into a staging scheme, which effectively separated patients into groups with homogeneous prognosis and response to treatment, and thus serves to aid in the selection of appropriate therapy.

We attempted to study a possible involvement of levels of high-density lipoprotein cholesterol (HDL-C in steady-state children with SCD, once that this lipid marker has been correlated with anti-inflammatory, anti-oxidative, anti-aggregation, anti-coagulant and pro-fibrinolytic activities, important aspects to be considered in sickle cell disease pathogenesis. Methods We prospectively analyzed biochemical, inflammatory and hematological biomarkers of 152 steady-state infants with SCD and 132 healthy subjects using immunochemistry, immunoassay and electronic cell counter respectively. Clinical data were collected from patient medical records. Results Of the 152 infants investigated had a significant positive association of high-density lipoprotein cholesterol with hemoglobin (P Conclusions We hypothesize that some SCD patients can have a specific dyslipidemic subphenotype characterized by low HDL-C with hypertriglyceridemia and high VLDL-C in association with other biomarkers, including those related to inflammation. This represents an important step toward a more reliable clinical prognosis. Additional studies are warranted to test this hypothesis and the probably mechanisms involved in this complex network of markers and their role in SCD pathogenesis.

    Full Text Available BackgroundMetabolic health is an emerging concept that is highly correlated with various metabolic complications, and adipocytokines have been causally linked to a wide range of metabolic diseases. Thus, this study compared serum adipocytokine levels according to metabolic health and obesity status.MethodsFour hundred and fifty-six nondiabetic subjects (mean age, 40.5 years were categorized into four groups according to metabolic health and obesity status: metabolically healthy nonobese (MHNO, metabolically healthy obese (MHO, metabolically unhealthy nonobese (MUHNO, and metabolically unhealthy obese (MUHO. Being metabolically healthy was defined as the presence of fewer than two of the following five metabolic abnormalities: high blood pressure, high fasting blood glucose, high triglyceride, low high density lipoprotein cholesterol, and being in the highest decile of the homeostatic model assessment of insulin resistance index. Obesity status was assessed using body mass index (BMI, with obesity defined as a BMI higher than 25 kg/m2. Levels of serum interleukin-6 (IL-6, monocyte chemoattractant protein-1 (MCP-1, tumor necrosis factor α (TNF-α, and adipocyte fatty acid binding protein (A-FABP were also evaluated.ResultsOf the 456 subjects, 247 (54.2% were in the MHNO group, 66 (14.5% were in the MHO group, 66 (14.5% were in the MUHNO group, and 77 (16.9% were in the MUHO group. There were no significant differences in IL-6 or MCP-1 levels among the groups, but levels of TNF-α and A-FABP were significantly higher in the MUHNO group compared to the MHNO group.ConclusionHigh TNF-α and A-FABP levels are significantly associated with metabolically unhealthiness in nonobese Korean individuals.

    Full Text Available Background. To investigate whether serum alanine aminotransferase (ALT levels within normal range were associated with augmentation index (AIx and cardiometabolic risk factors in nondrinkers and drinkers in Chinese community-dwelling population. Methods. There were 4165 participants with serum ALT levels within normal range. Results. Alcohol drinking was observed in 1173 participants (28.2%. In multivariate analysis, serum ALT levels of nondrinkers were independently associated with age, sex, body mass index (BMI, hypertension, diabetes mellitus, diastolic blood pressure, triglyceride, low-density lipoprotein-cholesterol (LDL-c, and AIx, while serum ALT levels of drinkers were independently associated with age, sex, BMI, triglyceride, and LDL-c (p<0.05 for all. Conclusions. Associations of serum ALT levels within normal range with age, sex, body height and weight, and blood lipid were simultaneously present in participants with and without alcohol drinking, while associations of serum ALT levels within normal range with AIx, blood pressure, and glucose were seen in nondrinkers rather than in drinkers. These findings not only provide the evidence that serum ALT levels, even within the normal range, have different associations with arteriosclerosis and cardiometabolic risk factors in nondrinkers and drinkers but also are helpful in understanding the underlying pathophysiologic mechanisms linking the hepatic function to arteriosclerosis and cardiometabolic risk factors.

    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

    Secretion of 27-hydroxycholesterol (27OHC) from macrophages is considered as an alternative to HDL-mediated reverse transport of excess cholesterol. We investigated 27OHC-concentrations in plasma of humans and mice with monogenic disorders of HDL metabolism. As compared to family controls mutations...... activities of LCAT and CETP, respectively, than the formation and transfer of cholesterylesters. 27OHC plasma levels were also decreased in apoA-I-, ABCA1- or LCAT-knockout mice but increased in SR-BI-knockout mice. Transplantation of ABCA1- and/or ABCG1-deficient bone marrow into LDL receptor deficient mice...... decreased plasma levels of 27OHC. In conclusion, mutations or absence of HDL genes lead to distinct alterations in the quantity, esterification or lipoprotein distribution of 27OHC. These findings argue against the earlier suggestion that 27OHC-metabolism in plasma occurs independently of HDL....

    Accumulating evidence suggests that fat distribution is a better predictor of cardiovascular disease than body mass index (BMI). The aim of this study was to investigate the association of android and gynoid fat percentages with lipid profiles to determine whether android and/or gynoid fat percentages are associated with serum lipid levels. A population-based cross-sectional study. Five thousand six hundred and ninety-six adults (20 years and older) who participated in the National Health and Nutrition Examination Survey 2003-2006. The regional body composition in the android and gynoid regions was defined by dual energy X-ray absorptiometry (DXA). The estimation of lipid risk profiles included total cholesterol, high-density lipoprotein (HDL) -cholesterol, low-density lipoprotein (LDL) -cholesterol and triglycerides (TG). Regardless of gender, android and gynoid body fat percentages were positively and significantly correlated with BMI and waist circumference. After adjustment for age, ethnicity, education, smoking, alcohol consumption, dyslipidaemia and BMI, increases in android fat percentage were significantly associated with total cholesterol, TG and HDL cholesterol in males, and total cholesterol, HDL cholesterol and LDL cholesterol in females. The gynoid fat percentages showed a positive correlation with total cholesterol in males, whereas gynoid fat accumulation in females showed a favourable association with TG and HDL cholesterol. The observed associations differed according to ethnic groups. Our results suggest that regional fat distribution in the android and gynoid regions have different effects on lipid profiles, and that fat in the android region, rather than the gynoid region, may be an important factor in determining the risk of cardiovascular disease. © 2014 John Wiley & Sons Ltd.

    Full Text Available Background: Circulating serum levels of oxidized low-density lipoprotein, β2-glycoprotein I complex (oxLDL-GP, have been previously correlated with adverse cardiovascular events and have been shown to be reduced by consumption of enzymatically liberated extra virgin salmon oil (EVSO. This mouse study measured the changes in the oxLDL-GP lowering effect when consuming EVSO with varying levels of EPA+DHA (eicosapentenoic acid and docosahexenoic acid as well as when consuming EVSO that was subjected to various processing treatments commonly carried out during fish oil production. Methods: Sprague Dawley mice were fed a diet containing eight different EVSO’s incorporated into a normal diet at the Human Equivalent Dose (HED of 1000 mg for 8 weeks. Serum was collected at the start and at the end of the trial and the oxLDL-GP concentrations were measured using an ELISA assay. Statistical analysis of the results was carried out using a 1-tail, paired Student t-Test. Results: In order to lower circulatory oxLDL-GP levels, the mice had to consume a minimum of 80 mg per day HED of EPA+DHA. Heat treatment of the EVSO did not affect this bioactivity but hydrolysis with acid or base and re-esterification to the triglyceride form or significant oxidation (rancidity rendered the oil inactive on this important cardio-vascular disease (CVD biomarker. Conclusions: This result shows that harsh processing conditions on fish oils can lead to the destruction of biological efficacy in spite of increasing the concentration of typical fish oil bioactive constituents such as EPA+DHA. It also lends support to the developing nutrition theory that eating highly-refined, processed or concentrated-ingredient supplements derived from functional foods may not be able to reproduce their full nutritive and health-benefiting effects

    Full Text Available BACKGROUND/OBJECTIVE: Gene-gene interactions in the reverse cholesterol transport system for high-density lipoprotein-cholesterol (HDL-C are poorly understood. The present study observed gene-gene combination effect and interactions between single nucleotide polymorphisms (SNPs in ABCA1, APOA1, SR-B1, and CETP in serum HDL-C from a cross-sectional study in the Japanese population. METHODS: The study population comprised 1,535 men and 1,515 women aged 35-69 years who were enrolled in the Japan Multi-Institutional Collaborative Cohort (J-MICC Study. We selected 13 SNPs in the ABCA1, APOA1, CETP, and SR-B1 genes in the reverse cholesterol transport system. The effects of genetic and environmental factors were assessed using general linear and logistic regression models after adjusting for age, sex, and region. PRINCIPAL FINDINGS: Alcohol consumption and daily activity were positively associated with HDL-C levels, whereas smoking had a negative relationship. The T allele of CETP, rs3764261, was correlated with higher HDL-C levels and had the highest coefficient (2.93 mg/dL/allele among the 13 SNPs, which was statistically significant after applying the Bonferroni correction (p<0.001. Gene-gene combination analysis revealed that CETP rs3764261 was associated with high HDL-C levels with any combination of SNPs from ABCA1, APOA1, and SR-B1, although no gene-gene interaction was apparent. An increasing trend for serum HDL-C was also observed with an increasing number of alleles (p<0.001. CONCLUSIONS: The present study identified a multiplier effect from a polymorphism in CETP with ABCA1, APOA1, and SR-B1, as well as a dose-dependence according to the number of alleles present.

    Aims. To evaluate potential health risk and benefits of fish consumption, the association of fish consumption with total mercury levels in red blood cells (RBCs) and serum eicosapentaenoic acid (EPA) concentrations was examined. Subjects and Methods. Study subjects were 269 Japanese (98 men and 171 women) living in a remote island of Kagoshima, and their blood was drawn in 1994. Results. Total mercury levels were related to weekly fish consumption among women (P=0.035) but not among men (P=0.643). However, serum EPA levels were not related to fish consumption in both women and men. In contrast, EPA levels in the high-density lipoprotein (HDL) fraction of the sera were significantly related to fish consumption (P values for men and women were 0.014 and 0.073, resp.). Interestingly, mercury levels were related to serum EPA levels and EPA in the HDL fraction of the sera (P=0.001) among women (P=0.005) but not among men. Sex differences in fish species consumed may be an explanation for the observed sex difference. Conclusion. Those findings suggest that the health benefit of fish consumption can be maximized by the careful selection of fish species consumed

    Serum prostate-specific antigen (PSA) is an important tumour, marker which is widely used to trigger trans-rectal ultrasound (TRUS)-guided prostate biopsy. However, the PSA levels vary with race and ethnicity. Therefore, there is a need to have an Indian reference range. All adult male patients meeting the inclusion and exclusion criteria were enrolled in this study. They were subjected to assessment of serum total PSA, digital rectal examination and trans-abdominal ultrasound. If any one or more of these were found abnormal, then a TRUS-guided 12-core prostate biopsy was done. Patients who were detected to have prostatic cancer were excluded from the final analysis. The data so obtained was grouped among the following three age groups: 40-49, 50-59 and 60-70 years, and the age-specific PSA values, prostatic volume and PSA density were found. A total of 1772 patients were analysed. The mean serum total PSA was 1.76 ng/ml with a standard deviation of 2.566 ng/ml. Group-wise age distribution of the mean serum total PSA was 1.22, 1.97 and 2.08 ng/ml in 40-49, 50-59 and 60-70 years age groups. The mean total PSA and the age-specific PSA range tend to be lower in the Indians than the Western population.

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

    Background Exposure to pesticides has been reported to increase the risk of Parkinson disease (PD), but identification of the specific pesticides is lacking. Three studies have found elevated levels of organochlorine pesticides in postmortem PD brains. Objective To determine whether elevated levels of organochlorine pesticides are present in the serum of patients with PD. Design Case-control study. Setting An academic medical center. Participants Fifty patients with PD, 43 controls, and 20 patients with Alzheimer disease. Main Outcome Measures Levels of 16 organochlorine pesticides in serum samples. Results β-Hexachlorocyclohexane (β-HCH) was more often detectable in patients with PD (76%) compared with controls (40%) and patients with Alzheimer disease (30%). The median level of β-HCH was higher in patients with PD compared with controls and patients with Alzheimer disease. There were no marked differences in detection between controls and patients with PD concerning any of the other 15 organochlorine pesticides. Finally, we observed a significant odds ratio for the presence of β-HCH in serum to predict a diagnosis of PD vs control (odds ratio, 4.39; 95% confidence interval, 1.67–11.6) and PD vs Alzheimer disease (odds ratio, 5.20), which provides further evidence for the apparent association between serum β-HCH and PD. Conclusions These data suggest that β-HCH is associated with a diagnosis of PD. Further research is warranted regarding the potential role of β-HCH as a etiologic agent for some cases of PD.

    To evaluate the platelet activating factor acetyl hydrolyze (PAF-AH), oxidized low-density lipoprotein (ox-LDL), paraoxonase 1 (PON1), arylesterase (ARE) levels and the effects of metformin and Diane-35 (ethinyl oestradiol + cyproterone acetate) therapies on these parameters and to determine the PON1 polymorphisms among PCOS patients. Ninety patients with PCOS, age 30, and body mass index-matched healthy controls were included in the study. Patients were divided into three groups: metformin treatment, Diane-35 treatment and no medication groups. The treatment with metformin or Diane-35 was continued for 6 months and all subjects were evaluated with clinical and biochemical parameters 6 months later. One-way Anova test, t test and non-parametric Mann-Whitney U tests were used for statistical analysis. PAF-AH and ox-LDL levels were statistically significantly higher in untreated PCOS patients than controls, and they were statistically significantly lower in patients treated with metformin or Diane-35 than untreated PCOS patients. In contrast, there were lower PON1 (not statistically significant) and ARE (statistically significant) levels in untreated PCOS patients than the control group and they significantly increased after metformin and Diane-35 treatments. In PCOS patients serum PON1 levels for QQ, QR and RR phenotypes were statistically significantly lower than the control group. In patients with PCOS, proatherogenic markers increase. The treatment of PCOS with metformin or Diane-35 had positive effects on lipid profile, increased PON1 level, which is a protector from atherosclerosis and decreased the proatherogenic PAF-AH and ox-LDL levels.

    Socio-demographic factors affect the development and lives of children and adolescents. We examined links between serum lipids and apolipoproteins and socio-demographic factors in the Leipzig Research Centre for Civilization Diseases Child (LIFE Child) study. The Winkler index and the Family Affluence Scale were used to define characteristics of the social status of 938 boys and 860 girls aged from birth to 19 years. We then used univariate and multivariate regression analyses to examine the socio-demographic impact on total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL), cholesterol triglycerides and apolipoproteins A1 (ApoA1) and B (ApoB). No significant influences on the Winkler index or the Family Affluence Scale were observed regarding the concentrations of serum lipids for total cholesterol or LDL cholesterol. However, and most importantly, children and adolescents with high social status and high family affluence showed significantly higher HDL cholesterol and ApoA1 levels than those with lower individual totals. A higher Winkler index was associated with significantly lower values for triglycerides and ApoB. Adolescents with higher family wealth and social status showed a lower cardiovascular risk profile, as measured by the concentrations of HDL cholesterol and triglycerides as well as ApoA1 and B. ©2016 Foundation Acta Paediatrica.

    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

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

    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

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 PurposePrevious reports show an association between high serum ferritin levels and metabolic syndrome (MS in adults. In adolescents, little information is available with obesity and serum ferritin levels.MethodsThis is a cross-sectional study. Data were obtained from the 5th Korean National Health and Nutrition Examination Survey (K-NHANES conducted during 2010 by the Korean Ministry of Health and Welfare. A total of 849 subjects aged 10-18 years participated in the 2010 survey. A body mass index (BMI ≥95th percentile for age and sex or a BMI ≥25 was used to diagnose as obesity.ResultsThe weighted prevalence of obesity was 13.4% (62/462 in male and 8.5% (33/387 in female. We observed significantly higher serum ferritin in male than in female (mean±standard error [SE], 50.5±2.3 µU/L vs. 30.6±1.3 µU/L; P<0.0001. In male, serum ferritin is positively correlated with age (P<0.0001. White blood cell (WBC count, serum fasting blood sugar, triglyceride (TG, total cholesterol, low-density lipoprotein, insulin, homeostasis model assessment-insulin resistance (HOMA-IR, systolic and diastolic blood pressure, and ferritin levels were higher and high-density lipoprotein (HDL were lower in the obesity than in the normal group. In female adolescents, WBC count, TG, insulin, and HOMA-IR were higher and HDL were lower in the obesity than in the normal group. In male, serum ferritin levels showed positive association with obesity (β=21.196, P=0.016.ConclusionSerum ferritin levels appear to be associated with obesity in Korean male adolescents.

    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.

    We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p 286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

    Full Text Available Introduction. The association of diabetes and atherosclerosis with disorders of lipids and lipoproteins, notably high apolipoprotein B (apoB and low apolipoprotein A1(apoA1 is well established. Because of the beginning of the atherosclerosis' process from early life, in this study, the plasma levels of apoA1 and apoB were compared in diabetic children with type I diabetes mellitus(DM, healthy children with diabetic parents (HDPs,and healthy children with nondiabetic parents (HNDPs. Methods. This case-control study was conducted among 90 children aged 9–18 years. Serum levels of apoA and apoB were compared among 30 diabetic children (DM, 30 healthy children with diabetic parents (HDPs, and 30 healthy children with nondiabetic parents (HNDP. Results. The mean serum apoA1 was higher in DM (153±69 mg/dL followed by HNDPs (138±58 mg/dL and HDPs (128±56 mg/dl, but the difference was not statistically significant. The mean apoB value in HNDPs was significantly lower than DM and HDPs (90±21 mg/dL versus 127±47 and 128±38 mg/dL, P0.05. Conclusions. Diabetic children and healthy children with diabetic parent(s are at higher risk of dyslipidemia and atherosclerosis. Thus for primordial and primary prevention of atherosclerosis, we suggest screening these children for low plasma apoA1 and high plasma apoB levels.

    Full Text Available BACKGROUND: Considerable evidence suggests that bilirubin is a potent physiologic antioxidant that may provide important protection against cardiovascular disease (CVD and inflammation. We investigated the relationship between serum total bilirubin (TB levels and arterial stiffness, measured by the brachial-ankle pulse wave velocity (baPWV, in patients with type 2 diabetes. METHODS: We conducted a cross-sectional analysis of 1,711 subjects with type 2 diabetes (807 men and 904 women; mean age, 57.1 years. The subjects were stratified based on gender-specific tertiles of TB values, and a high baPWV was defined as greater than 1,745 cm/s ( >75th percentile. RESULTS: The serum TB concentration was negatively correlated with the duration of diabetes, HbA1c, the 10-year Framingham risk score, and baPWV and was positively correlated with high-density lipoprotein cholesterol and the eGFR in both genders. Inverse association between TB categories and unadjusted prevalence of high PWV was only observed in women. After adjusting for confounding factors, the TB levels were inversely associated with a greater risk of a high baPWV, both as a continuous variable [a 1-SD difference; odds ratio (OR, 0.70; 95% confidence interval (CI, 0.54-0.90; P = 0.005] and when categorized in tertiles (the highest vs. the lowest tertile; OR, 0.49; 95% CI, 0.28-0.85; P = 0.011 in women but not in men. The relationship remained significant even after adjusting for retinopathy and nephropathy. CONCLUSIONS: Low TB levels were significantly associated with arterial stiffness in Korean women with type 2 diabetes. Our data suggested that bilirubin may protect against macrovascular disease in diabetic women.

    Full Text Available Adipokines and ghrelin play role in insulin resistance, the key pathophysiological abnormality in patients with nonalcoholic fatty liver diseases. In the present study, relationship between nonalcoholic steatohepatitis (NASH and serum adipokine and ghrelin levels was investigated. Thirty seven patients with biopsy-proven NASH and 25 age- and sex-matched controls were enrolled. Ten of NASH patients (27% had diabetes mellitus (n=5 or impaired glucose tolerance (n=5. Body mass index (BMI was less than 30 kg/m2 in 67.6% of patients, while in the remaining 32.4% it was more than 30 kg/m2. Serum adiponectin, leptin, TNF-α, and ghrelin were determined. Serum leptin (15.49±4.84 vs 10.31±2.53 and TNF-α (12.1±2.7 vs 10.31±2.56 levels were significantly higher in the NASH group compared to in the control group (P30 or glucose tolerance was impaired or not (P>.05. Additionally, neither adipokines nor ghrelin was correlated with histopathological grade and stage (P>.05. In conclusion; there is a significant relationship between NASH and adipokines and ghrelin independent from BMI and status of the glucose metabolism. These cytokines that appear to have role in the pathogenesis of NASH, however, do not have any effect upon the severity of the histopathology.

    Adiponectin, an adipo cytokine, is secreted from the adipose tissue and plays an important role in obesity, type II diabetes and cardiovascular disease. This study aimed to determine the concentration of serum adiponectin in type I diabetic children and to establish its association with microvascular complications. For this reason, weight (kg), height (m), body mass index (BMI) (kg/m2), random blood sugar, HbAIc, kidney functions, urinary microalbuminuria, lipid profiles and serum adiponectin were assessed in 25 children (11 males, 14 females) with type I diabetes and twenty healthy control children. Careful history, clinical examination, acetomorphine and pirbuterol assessment were done for all patients and controls. The diabetic patients were stratified depending on the pubertal stage into pre-pubertal group and pubertal group, and according to gender into male group and female group. The results obtained displayed significant elevated values for random blood glucose (P<0.001), HbAIc (P<0.001), total cholesterol (P<0.05), low density lipoprotein (LDL) (P<0.05), BUN (P<0.001), creatinine (P<0.05), urinary microalbuminuria (P<0.001) and serum adiponectin (P<0.001) in diabetic children and control. In patients suffering from microvascular diabetic complications as retinopathy, nephropathy and neuropathy, serum adiponectin level showed high significant increase in patients with diabetic nephropathy and neuropathy than without. On the other hand, patients with retinopathy had no significant increase in serum adiponectin as compared with patients without retinopathy but this result may be due to small sample size. Positive significant correlation was detected between serum adiponectin and HbAIc, total cholesterol and urinary microalbuminuria in the same patients. Negative significant correlation was observed between serum adiponectin level and body mass index (BMI). It could be concluded that serum adiponectin which increased in diabetic children than healthy control

    Objective Effects of red palm oil on major plasma carotenoids, tocopherol, retinol and serumlipids were evaluated when used in Chinese diet. Methods Red palm oil group (RPO) composed of 20 male subjects(aged 18-32) and soybean oil group (SBO) composed of 22 male subjects (aged18-32). Dietary fat provided about 28% of total calories, and the test oil accounted for about 60% of total dietary fat. In the 3 weeks of pretest period, diets were prepared with soybean oil, and then in the next 6 weeks subjects in each group consumed the diet prepared by test oil. Results Plasmaα-carotene, β-carotene and lycopene concentration of RPO group significantly increased at the time of interim (21 days) and of the end (42 days) (P<0.05), and α-tocopherol concentration significantly increased at the time of the end (42 days) in this study. Though Chinese plasma retinol level was relatively low when compared with that of Westerners, red palm oil diet showed no significant effect on adult Chinese plasma retinol level. Serum concentration of total cholesterol, triglyceride, high density lipoprotein cholesterol, apolipoprotein AI and apolipoprotein B of all subjects showed no significant changes in RPO group during the study. Conclusions The data in our study suggest that red palm oil is a good source of carotenoids and vitamin E when used in Chinese diet preparation, and it can significantly increase plasma concentration of α-carotene, β-carotene, lycopene andα-tocopherol.

    Mullan, Ronan Hugh

    2012-02-01

    Acute phase apoprotein Serum Amyloid A (A-SAA), which is strongly expressed in rheumatoid arthritis synovial membrane (RA SM), induces angiogenesis, adhesion molecule expression, and matrix metalloproteinase production through the G-coupled receptor FPRL-1. Here we report alternative signaling through the high-density lipoprotein receptor scavenger receptor-class B type 1 (SR-B1). Quantitative expression\\/localization of SR-B1 in RA SM, RA fibroblast-like cells (FLCs), and microvascular endothelial cells (ECs) was assessed by Western blotting and immunohistology\\/fluorescence. A-SAA-mediated effects were examined using a specific antibody against SR-B1 or amphipathic alpha-Helical Peptides (the SR-B1 antagonists L-37pA and D-37pA), in RA FLCs and ECs. Adhesion molecule expression and cytokine production were quantified using flow cytometry and ELISA. SR-B1 was strongly expressed in the RA SM lining layer and endothelial\\/perivascular regions compared with osteoarthritis SM or normal control synovium. Differential SR-B1 expression in RA FLC lines (n = 5) and ECs correlated closely with A-SAA, but not tumor necrosis factor alpha-induced intercellular adhesion molecule-1 upregulation. A-SAA-induced interleukin-6 and -8 production was inhibited in the presence of anti-SR-B1 in human microvascular endothelial cells and RA FLCs. Moreover, D-37pA and L-37pA inhibited A-SAA-induced vascular cell adhesion molecule-1 and intercellular adhesion molecule expression from ECs in a dose-dependent manner. As SR-B1 is expressed in RA synovial tissue and mediates A-SAA-induced pro-inflammatory pathways, a better understanding of A-SAA-mediated inflammatory pathways may lead to novel treatment strategies for RA.

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

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

    Full Text Available Rett syndrome (RTT and autism spectrum disorders (ASDs are not merely expression of brain dysfunction but also reflect the perturbation of physiological/metabolic homeostasis. Accordingly, both disorders appear to be associated with increased vulnerability to toxicants produced by redox imbalance, inflammation, and pollution, and impairment of systemic-detoxifying agents could play a role in the exacerbation of these detrimental processes. To check this hypothesis, the activities of two mechanistically related blood-based enzymes, paraoxonase-1 (arylesterase, paraoxonase, and lactonase, and lipoprotein-associated phospholipase A2 (Lp-PLA2 were measured in the serum of 79 ASD and 95 RTT patients, and 77 controls. Lactonase and Lp-PLA2 showed a similar trend characterized by significantly lower levels of both activities in ASD compared to controls and RTT (p<0.001 for all pairwise comparisons. Noteworthy, receiving operator curve (ROC analysis revealed that lactonase and, mostly, Lp-PLA2 were able to discriminate between ASD and controls (lactonase: area under curve, AUC = 0.660; Lp-PLA2, AUC = 0.780, and, considering only females, between ASD and RTT (lactonase, AUC = 0.714; Lp-PLA2, AUC = 0.881. These results suggest that lactonase and, especially, Lp-PLA2 activities might represent novel candidate biomarkers for ASD.

    Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

    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.

    Red palm oil (RPO) is a rich natural source of antioxidant vitamins, namely carotenes, tocopherols and tocotrienols. However, it contains approximately 50 % saturated fatty acids the regular consumption of which could negatively modify lipid profile. The aim of our study was to test whether 7 weeks of RPO supplementation (1 g/kg body weight/day) would affect blood glucose and lipid metabolism in adult male Wistar rats with altered thyroid status. We induced hypothyroidism and hyperthyroidism in rats by oral administration of either methimazole or mixture of thyroid hormones. Different thyroid status (EU - euthyroid, HY - hypothyroid and HT - hyperthyroid) was characterized by different serum thyroid hormones levels (total and free thyroxine and triiodothyronine), changes in the activity of a marker enzyme of thyroid status - liver mitochondrial glycerol-3-phosphate dehydrogenase, and altered absolute and relative heart weights. Fasting blood glucose levels were higher in HT rats in comparison with EU and HY rats, but the changes caused by RPO supplementation were not significant. The achievement of the HY status significantly increased serum levels of total cholesterol, as well as with high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol: 2.43+/-0.15, 1.48+/-0.09, 0.89+/-0.08 mmol/l, compared to EU: 1.14+/-0.06, 0.77+/-0.06, 0.34+/-0.05 mmol/l and HT: 1.01+/-0.06, 0.69+/-0.04, 0.20+/-0.03 mmol/l, respectively. RPO supplementation did not increase significantly levels of blood lipids but tended to increase glutathione levels in the liver. In conclusion, RPO supplementation did not induce the presumed deterioration of glucose and lipid metabolism in rats with three well-characterized alterations in thyroid status.

    Cortisol measurement is indicated in suspected over or under production of cortisol by the adrenal cortex. The finding of low cortisol can create concern and initiate further investigations for the exclusion of adrenal insufficiency. Cushing's syndrome is frequently included in the differential diagnosis of obesity. Some literature describes reduced serum cortisol levels in obesity, however, this is not a well-recognized phenomenon. The aim of this study was to determine the relationship between body mass index (BMI) and serum cortisol levels. Seventy healthy participants agreed to take part in the study. The anthropometric measurements (weight, height, and waist and hip circumferences) were done. Exclusion criteria include those with a history of adrenal/pituitary disease or medications altering cortisol level. The basal cortisol (BC) sample was taken at 8 a.m. immediately before administration of an intravenous bolus injection of 250 μg adrenocorticotropic hormone (ACTH). BMI categories were defined as normal and high if BMI was 18.5-24.99 kg/m² and ≥ 25 kg/m², respectively. Forty (57.1%) participants had normal BMI while 30 (42.9%) participants had BMI ≥ 25 kg/m² (P0 = 0.053). The mean BC level was lower in participants with BMI ≥ 25 kg/m² but not significant. There was a negative correlation between BMI and BC level ( r = -0.205, P = 0.88) while a positive correlation existed between stimulated cortisol level and BMI (r = 0.009, P = 0.944). Persons with BMI above 25 kg/m² had lower BC level though not statistically significant, the trend was noticed. Subjecting people whose BMI is above 25 kg/m² to further stimulation with ACTH because of low BC is not advised because their response to ACTH stimulation was similar to those who have normal BMI.

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

    The serum gastrin level (SGL) is studied in dynamics during each lunar month of pregnancy in order to accumulate data which may serve the purpose of a tentative standard for serum gastrin level in this peculiar physiologic condition. A group of 110 pregnant women with a normal development of pregnancy, as documented by the clinical and paraclinical examination, are covered by the study. Blood samples are taken before meal, and a radioimmunologic method is used for SGL assessment. The number of women analyzed and the mean age by lunar months are shown. The normal value established in nonpregnant women of the same age group is 28+-7 mg/ml, relative to which the average values during the first five i.m. do not show statistically significant differences. During the 6th l.m. SGL increases to 68.5 mg/ml, while after the 7th l.m. values are recorded exceeding 1aa mg/ml with a maximum observed in the 8th and 9th l.m. The mechanisms eventually involved in the occurrence of gastrinemia during the second half of pregnancy are discussed, e.g. 1/mechanical compression of the stomach by the progressively growing uterus, 2/decreased breakdown, inhibition and elimimation of the hormone by the kidneys, and 3/possible correlative dependence between changes in SGL and changes in the level of hormones playing a predominant role in the hormonal status after the fifth month of pregnancy.

  14. Lipasin, a novel nutritionally-regulated liver-enriched factor that regulates serum triglyceride levels.

    The metabolic syndrome, a common disorder including glucose intolerance and dyslipidemia, poses a major public health issue. Patients with high blood lipids, such as triglycerides, are at high risk in developing atherosclerotic cardiovascular diseases. To identify genes involved in metabolism, we performed RNA-seq experiments on the liver and fat in mice treated with a high-fat diet or fasting, and identified Gm6484 (named Lipasin) as a novel nutritionally regulated gene. Human LIPASIN is liver specific, while the mouse one is enriched in the liver and fat, including both brown and white adipose tissues. Obesity increases liver Lipasin, whereas fasting reduces its expression in fat. ANGPTL3 (Angiopoietin-like 3) and ANGPTL4 are critical regulators of blood lipids. LIPASIN shares homology with ANGPTL3's N-terminal domain that is needed for lipid regulation, and with ANGPTL4's N-terminal segment that mediates lipoprotein lipase (LPL) binding. Lipasin overexpression by adenoviruses in mice increases serum triglyceride levels, and a recombinant Lipasin inhibits LPL activity. Therefore, a potential mechanism for Lipasin-mediated triglyceride elevation is through reduced triglyceride clearance by LPL inhibition. Lipasin is thus a novel nutritionally-regulated liver-enriched factor that plays a role in lipid metabolism. Copyright © 2012 Elsevier Inc. All rights reserved.

    The objective of the current study was to determine the relationship between serum vitamin D levels and the severity of atopic dermatitis (AD) in a Brazilian population. This was a cross-sectional study of patients younger than 14 years of age seen from April to November 2013. All patients fulfilled the Hanifin and Rajka Diagnostic Criteria for AD diagnosis. Disease severity was determined using the SCORing Atopic Dermatitis index and classified as mild (50). Serum vitamin D levels were classified as sufficient (≥30 ng/mL), insufficient (29-21 ng/mL), or deficient (≤20 ng/mL). A total of 105 patients met the inclusion criteria. Mild AD was diagnosed in 58 (55.2%) children, moderate in 24 (22.8%), and severe in 23 (21.9%). Vitamin D deficiency was observed in 45 individuals (42.9%). Of these, 24 (53.3%) had mild AD, 13 (28.9%) moderate, and 8 (17.7%) severe. Insufficient vitamin D levels were found in 45 (42.9%) individuals; 24 (53.3%) had mild AD, 9 (20.0%) moderate, and 12 (26.7%) severe. Of the 15 individuals (14.2%) with sufficient vitamin D levels, 10 (60.7%) had mild AD, 2 (13.3%) moderate, and 3 (20.0%) severe. The mean vitamin D level was 22.1 ± 7.3 ng/mL in individuals with mild AD, 20.8 ± 6.5 ng/mL in those with moderate AD, and 21.9 ± 9.3 ng/mL in those with severe AD. Variables such as sex, age, skin phototype, season of the year, and bacterial infection were not significantly associated with vitamin D levels. Levels of 25-hydroxyvitamin D were deficient or insufficient in 85% of the children, but serum vitamin D concentrations were not significantly related to AD severity. © 2016 Wiley Periodicals, Inc.

    Inflammation plays a central role in the pathogenesis of metabolic syndrome (MetS). Cyclophilin B (CypB) can be constitutively secreted in response to inflammatory stimuli and oxidative stress, participating in tissue or systemic inflammation. We investigated the relationship between CypB and MetS in both humans and mice. Serum CypB levels were determined in 211 subjects with MetS and 292 subjects without MetS (non-MetS) (133 healthy controls and 159 high-risk subjects with one to two MetS components). Additionally, CypB expression in metabolic organs was examined in mice fed with high-fat diet (HFD) and genetically obese (ob/ob) mice. Serum CypB level was significantly higher in MetS subjects compared with both groups of non-MetS subjects (193.80 ± 83.22 vs. 168.38 ± 65.01 vs. 124.26 ± 47.83 ng/mL, P  CypB level was significantly higher in subjects with hypertension, central obesity, diabetes mellitus or hyperglycemia, elevated levels of triglycerides, or reduced levels of high-density lipoprotein than in those without. Moreover, CypB was positively associated with the number of MetS components ( r  = 0.404, P  CypB level reflected more severe MetS. Multivariate regression revealed that a one SD increase in CypB was associated with an odds ratio of 1.506 (1.080-2.101, P  = 0.016) for MetS prevalence after adjusting for age, gender, conventional risk factors, and medication. Stratified analyses by age and gender demonstrated that subjects >60 years old with higher CypB levels were more likely to have MetS, and the risk for MetS was higher and more significant in women compared with men. Additionally, CypB expression levels were lower at baseline and dramatically enhanced in metabolic organs (such as the liver) and visceral and subcutaneous adipose tissue from HFD-induced obese mice and ob/ob mice. Increased CypB levels were significantly and independently associated with the presence and severity of MetS, indicating that CypB could be

    Tributyltin (TBT), a toxic environmental contaminant, has been widely utilized for various industrial, agricultural and household purposes. Its usage has led to a global contamination and its bioaccumulation in aquatic organisms and terrestrial mammals. Previous studies suggest that TBT has debilitating effects on the overall immune function of animals, rendering them more vulnerable to diseases. TBT (at concentrations that have been detected in human blood) alters secretion of inflammatory cytokines from human lymphocytes ex vivo. Thus, it is important to determine if specified levels of TBT can alter levels of cytokines in an in vivo system. Mice were exposed to biologically relevant concentrations of TBT (200, 100 or 25 nM final concentrations). The quantitative determination of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL2, IL5, IL7, IL12βp40, IL13, IL15, KC, MIP1β, MIP2 and RANTES was performed in mouse sera by MAGPIX analysis and Western blot. Results indicated alterations (both decreases and increases) in several cytokines. The pro-inflammatory cytokines IFNγ, TNFα, IL-1β, IL-2, IL5, IL12βp40, and IL-15 were altered as were the chemokines MIP-1 and RANTES and the anti-inflammatory cytokine IL-13. Increases in IFNγ and TNFα were seen in serum of mice exposed to TBT for less than 24 hr. IL1-β, IL-12βp40, IL-5 and IL-15 were also modulated in mouse serum depending on the specific experiment and the exposure concentration. IL-2 was consistently decreased in mouse serum when animals were exposed to TBT. There were also TBT-induced increases in MIP-1β, RANTES, and IL-13. These results from human and murine samples clearly suggest that TBT exposures modulate the secretion inflammatory cytokines. PMID:27602597

  18. Deconvolution of serum cortisol levels by using compressed sensing.

    Directory of Open Access Journals (Sweden)

    Rose T Faghih

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

    Severe hypertriglyceridemia is a known, but uncommon complication of diabetic ketoacidosis. We discuss the case of a 23-year-old, previously healthy, woman who initially presented to the emergency department with abdominal pain. Grossly lipemic serum due to extremely high triglyceride (38.6 mmol/L) and cholesterol (23.2 mmol/L) levels were observed with a high blood glucose (23 mmol/L) and a low pH of 7.06 on a venous blood gas. She was treated successfully with fluids and insulin and had no sequale of pancreatitis or cerebral edema. Her triglycerides and cholesterol was normalized in three days and she was discharged home on insulin therapy after five days. Further history revealed a recent change in diet with no meat, fish or poultry consumption in the last 12 months and concomitantly an increase in carbohydrate intake which might have contributed to her extremely high serum lipid levels. This case demonstrates that clinicians should be mindful of the different presentations of diabetic ketoacidosis. Key words: diabetic ketoacidosis, hypertriglyceridemia, hyperlipidemia, vegan diet, carbohydrate diet. Correspondence: Hrafnkell Stefansson, hrafnkell.stefans@gmail.com.

    C-Reactive protein (CRP) has been associated with the macro- and microvascular effects of hypertension and diabetes mellitus. Referring to serum cortisol, it has been proposed to contribute to the pathogenesis of metabolic syndrome, and it has been demonstrated that weight loss normalizes cortisol levels and improves insulin resistance. The aims of this study were to analyze CRP and cortisol levels pre- and postoperatively in morbidly obese patients undergoing a laparoscopic sleeve gastrectomy and to correlate them with weight loss and parameters associated with cardiovascular risk. A prospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and May 2011 was performed. A total of 40 patients were included in the study. CRP levels decreased significantly 12 months after surgery (median reduction of 8.9 mg/l; p = 0.001). Serum cortisol levels decreased significantly 6 months after surgery (median reduction of 34.9 μg/dl; p = 0.001). CRP values reached the normal range (cortisol, a significant association was observed with the cardiovascular risk predictor (triglyceride/high-density lipoprotein cholesterol ratio) from the 6th month after surgery onward (Pearson correlation coefficient, 0.559; p = 0.008). CRP levels are increased preoperatively and in the postoperative course up to 1 year after surgery. Serum cortisol levels remain elevated until the 6th month after surgery. From this moment onward, serum cortisol is associated with the cardiovascular risk predictor reflecting the cardiovascular risk decreasement during the weight loss.

    Metabolic syndrome (MetS) as defined by the Adult Treatment Panel (ATP) III criteria includes 3 metabolic parameters: serum glucose, triglycerides, and high-density lipoprotein cholesterol (HDL-C) measurements. However, the impact of each of the 3 metabolic parameters on cardiovascular disease (CVD) risk in African American women (AAW) is unknown. Therefore, we investigated CVD risk clusters associated with each of the 3 metabolic components of MetS in adult nondiabetic, overweight/obese AAW. We studied the clinical and metabolic CVD risk factors of 258 AAW (mean age, 42.4 +/- 8.4 years; mean body mass index, 33.4 +/- 8.0 (kg/m(2)). Fasting serum insulin, glucose, and C-peptide levels were obtained in each subject. Waist circumference and systolic and diastolic blood pressure were measured. Insulin sensitivity (Bergman minimal model method) and insulin resistance (homeostasis model assessment) were calculated. We examined the prevalence of MetS and its components associated with each of the 3 metabolic components (ie, serum glucose, HDL-C, and triglycerides) of the MetS as defined by ATP III. Worsening of any of the 3 metabolic parameters was associated with increasing waist circumference but not with age and body mass index nor with insulin, C-peptide, homeostasis model assessment of insulin resistance, and insulin sensitivity. As a group, the prevalence of MetS was 35.5% in our AAW. The prevalence of MetS increased 3-fold from first to third tertiles of serum glucose (14.1% and 42.3%, respectively). Worsening of serum HDL-C from tertiles 3 to 1 was associated with significant increases in the prevalence of MetS (1.2% vs 42.3%, respectively). Comparing first with third tertile of triglycerides, there was no significant increase in MetS in our AAW (7% vs 17%). Contrasting the 3 metabolic components, the prevalence of MetS was higher in the third tertile of glucose (43.2%) and first tertile of HDL-C (42.3%) and least with the third tertile of triglycerides (17%).

    To determine a potential relationship between serum undercarboxylated (ucOC) concentration and cardiovascular risk factors in type 2 diabetes (T2D) patients and healthy subjects (HS). A cross-sectional study was conducted on 140 subjects classified into two groups, 70 with T2D and 70 HS. Medical history and physical examination with anthropometric measurements were obtained from all subjects. Body fat percentage was determined by bioelectrical impendency analysis. Serum ucOC concentration was determined by enzyme immunoassay, while serum levels of insulin and hsCRP were obtained using high sensitivity enzyme-linked immunosorbent assay. Insulin resistance was determined using the homeostasis model assessment-IR. Lipid profile [triglycerides, total cholesterol (TC), high-density lipoproteins (HDL-c), low density lipoproteins (LDL-c), very low-density lipoproteins] was determined by spectrophotometry and standard formulas when applicable. The T2D patient group showed significantly higher values of waist circumference, waist-to-hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP), current smoking, and alcohol use when compared to the HS group ( P correlated with body mass index (BMI) ( r = -0.236, P HDL-c ( r = -0.255, P correlated with LDL-c/HDL-c ratio ( r = 0.306, P HDL-c ratio ( r = 0.284, P correlated with BMI ( r = -0.310, P body-fat percentage ( r = -0.311, P correlated with DBP ( r = 0.450, P correlation between serum levels of ucOC and SBP ( r = 0.277, P adiposity parameters, blood pressure and lipid profile.

    The molecular mechanisms underlying sex differences in dyslipidemia are poorly understood. We aimed to distinguish genetic and hormonal regulators of sex differences in plasma lipid levels. We assessed the role of gonadal hormones and sex chromosome complement on lipid levels using the four core genotypes mouse model (XX females, XX males, XY females, and XY males). In gonadally intact mice fed a chow diet, lipid levels were influenced by both male-female gonadal sex and XX-XY chromosome complement. Gonadectomy of adult mice revealed that the male-female differences are dependent on acute effects of gonadal hormones. In both intact and gonadectomized animals, XX mice had higher HDL cholesterol (HDL-C) levels than XY mice, regardless of male-female sex. Feeding a cholesterol-enriched diet produced distinct patterns of sex differences in lipid levels compared with a chow diet, revealing the interaction of gonadal and chromosomal sex with diet. Notably, under all dietary and gonadal conditions, HDL-C levels were higher in mice with 2 X chromosomes compared with mice with an X and Y chromosome. By generating mice with XX, XY, and XXY chromosome complements, we determined that the presence of 2 X chromosomes, and not the absence of the Y chromosome, influences HDL-C concentration. We demonstrate that having 2 X chromosomes versus an X and Y chromosome complement drives sex differences in HDL-C. It is conceivable that increased expression of genes escaping X-inactivation in XX mice regulates downstream processes to establish sexual dimorphism in plasma lipid levels. © 2015 American Heart Association, Inc.

    Full Text Available Objective. Lipoprotein-associated phospholipase A2 (Lp-PLA2 is extensively expressed by advanced atherosclerotic lesions and may play a role in plaque instability. We selected a group of elderly subjects that underwent transcatheter aortic valve implantation (TAVI or balloon angioplasty (BA and separated them into two groups, diabetic and nondiabetic, to compare the level of Lp-PLA2 mass between them. Methods. 44 patients aged 79.6±5.6 years with symptomatic severe aortic valve stenosis underwent TAVI (n=35 or BA (n=9. 21 subjects had confirmed type 2 diabetes mellitus. Lp-PLA2 mass was measured using an enzyme-linked immunosorbent assay kit (USCN Life Science, China before and 3 days after the procedure. Results. Lp-PLA2 mass was significantly elevated in this population (1296±358 ng/mL before TAVI; 1413±268 ng/mL before BA and further increased after TAVI (1604±437 ng/mL, P<0.01 or BA (1808±303 ng/mL, P<0.01. Lp-PLA2 mass was significantly increased on the diabetic group before these interventions. Conclusion. Lp-PLA2 may be a novel biomarker for the presence of rupture-prone atherosclerotic lesions in elderly patients. Levels of Lp-PLA2 in diabetic patients may accompany the higher amount of small dense LDL particles seen in these subjects.

Leptin and resistin play an important role in energy homeostasis, glucose, lipid metabolism and regulation of body weight. The aim of the current study was to determine the concentration of leptin and resistin in pre-operational and post-operational periods of patients diagnosed as colorectal cancer.Materials and methods: The body mass index (BMI and values of leptin and resistin in blood at diagnosis were measured in 12 colorectal cancer patients in pre- and post-operational periods and in 12 age- and sex-matched controls. Serum leptin and resistin concentrations were measured by ELISA method.Results: Decreased leptin (1.95±0.62 ng/ml and resistin (4.32±1.83 ng/ml levels were found in pre-operational group compared with the control group (leptin: 6.12±0.82 ng/ml; resistin: 10.75±1.46 ng/ml (p0.05.Conclusion: We conclude that serum concentration of leptin and resistin may have a role in patients with colorectal cancers. Further studies are needed to investigate the possible prognostic value of leptin and resistin in clinical practice of patients with colorectal cancers.

    Full Text Available Background and Objectives: Low birth weight (LBW is a major public health problem. LBW is associated with increased neonatal morbidity and mortality. There is no consensus in the literature as to whether maternal copper nutrition is associated with pregnancy outcome or fetal growth. Methods: This case-control study was carried out at Alavi Hospital in Ardabil between August 2008 and August 2009. 56 women who had delivered low-birth- weight infants (<2500gr were taken as the case group, and from the mothers who had delivered normal birth weight infants (≥2500gr, 56 were selected at random as the control group. Venous blood samples were obtained from the mothers. Serum zinc level was determined by the Atomic Absorption Spectrophotometer method.Results: Mean of birth weight in infants, maternal age, body mass index in mothers and socioeconomic or demographic factors did not differ between cases and control groups. Maternal copper concentration (μg/dl differed between Cases and Controls; 231.75±38.12μg/dl vs. 204.42±31.30μg/dl respectively. There is a significant difference (p<0.001 in the serum copper concentration between the two groups.Conclusion: There is a negative relation between low infant birth weight and maternal copper concentration.

    Highlights: •Oxidized LDL enhances RANKL level in human smooth muscle cells. •The effect of OxLDL is mediated by the transcription factor NFAT. •UVA, H{sub 2}O{sub 2} and buthionine sulfoximine also increase RANKL level. •All these effects are observed in human fibroblasts and endothelial cells. -- Abstract: Receptor Activator of NFκB Ligand (RANKL) and its decoy receptor osteoprotegerin (OPG) have been shown to play a role not only in bone remodeling but also in inflammation, arterial calcification and atherosclerotic plaque rupture. In human smooth muscle cells, Cu{sup 2+}-oxidized LDL (CuLDL) 10–50 μg/ml increased reactive oxygen species (ROS) and RANKL level in a dose-dependent manner, whereas OPG level was not affected. The lipid extract of CuLDL reproduced the effects of the whole particle. Vivit, an inhibitor of the transcription factor NFAT, reduced the CuLDL-induced increase in RANKL, whereas PKA and NFκB inhibitors were ineffective. LDL oxidized by myeloperoxidase (MPO-LDL), or other pro-oxidant conditions such as ultraviolet A (UVA) irradiation, incubation with H{sub 2}O{sub 2} or with buthionine sulfoximine (BSO), an inhibitor of glutathione synthesis{sub ,} also induced an oxidative stress and enhanced RANKL level. The increase in RANKL in pro-oxidant conditions was also observed in fibroblasts and endothelial cells. Since RANKL is involved in myocardial inflammation, vascular calcification and plaque rupture, this study highlights a new mechanism whereby OxLDL might, by generation of an oxidative stress, exert a deleterious effect on different cell types of the arterial wall.

    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.

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

    Serum adiponectin and leptin levels have been shown to be related to obesity, insulin resistance and cardiovascular diseases (CVD). Opium addiction has a positive association with endocrine system disorders. The relationship between adipokines and opium addiction is unclear. In the present study, we aimed to determine serum adiponectin and leptin levels in opium addicted subjects. 176 men, 88 opium addicts and 88 non- addicts were randomly selected from subjects who participated in Kerman Coronary Artery Disease Risk factors Study (KERCADRS); a population-based study. Serum adiponectin and leptin levels were measured using ELISA and compared between two groups. We adjusted the effect of some confounding factors such as the patients' demographic, clinical and medical history in multivariate analysis model. The serum level of adiponectin in opium addicts was significantly lower than control group (6.5±3.6 vs. 9.8±8.1 µg/ml, Popium addicts, p = 0.80). In the multivariate analysis, after adjusting for age, cigarette smoking, body mass index, type 2 diabetes, hypertension, cholesterol, triglyceride and high and low density lipoproteins, the negative association between opium addiction and decreased adiponectin level was still present (β = -0.144, P value = 0.005). The results showed that opium addiction reduces serum adiponectin level. Since adiponectin has been shown to have anti-diabetic and anti-atherogenic effects, its reduction may account for increase in the risk of metabolic disorders such as insulin resistance and CVD amongst opium addicted patients.

    A three-phase study tested the hypothesis that the decrease in the high-density lipoprotein cholesterol (HDL-C) level observed in boys at puberty is related to an increase in the plasma testosterone concentration. In phase I, 57 boys aged 10 to 17 years were categorized into four pubertal stages based on clinical parameters and plasma testosterone levels. These four groups showed increasing plasma testosterone values and decreasing HDL-C levels. In phase II, 14 boys with delayed adolescence were treated with testosterone enanthate. Plasma testosterone levels during therapy were in the adult male range. Levels of HDL-C decreased by a mean of 7.4 mg/dL (0.20 mmol/L) and 13.7 mg/dL (0.35 mmol/L), respectively, after the first two doses. In phase III, 13 boys with delayed adolescence demonstrated increasing plasma testosterone levels and decreasing HDL-C levels during spontaneous puberty. Levels of HDL-C and apolipoprotein A-1 were correlated during induced and spontaneous puberty. Testosterone should be considered a significant determinant of plasma HDL-C levels during pubertal development

However, whether it can be used as a predictive factor in advanced lung adenocarcinoma patients treated with epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKI still remains undefined. This research aimed at studying the relationship of serum HDL-C baseline level and HDL-C kinetics to EGFR mutation, the efficacy of EGFR-TKI, and the predictive value of PFS. The presence of mutation rate in the 192 patients with lung adenocarcinoma was compared within stratified groups. Levels of baseline HDL-C and kinetics of HDL-C were analyzed retrospectively in patients treated with EGFR-TKI harboring EGFR mutation. Univariate and multivariate analyses were performed to investigate the prognostic value of HDL-C. EGFR mutation rate of HDL-C high-level group was significantly higher than that of low-level group (59.0% vs 35.6%, P=0.001. Multivariate logistic analysis showed that high-level HDL-C was an independent predictive factor for EGFR gene mutation (P=0.005; odds ratio =0.417; 95% confidence interval [CI], 0.227–0.768. Patients with a low level of HDL-C before therapy showed a progression of disease in most cases (P<0.001. According to HDL-C kinetics, patients who received EGFR-TKI treatment harboring EGFR mutation were divided into four groups. Univariate analysis showed that patients in nondecreased group had longer progression-free survival (P<0.001; hazard ratio =0.003; 95% CI, 0.001–0.018. Multivariate

  1. The Importance of Serum Cytokine Levels in Febrile Neutropenia

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

One of the main cardiovascular risk factors is low levels of high-density lipoprotein cholesterol (HDL-C. This study aimed to prospectively evaluate the effect of tomato consumption on HDL-C levels. Subject and methods: We conducted a randomized, single-blinded, controlled clinical trial. We screened 432 subjects with a complete lipid profile. Those individuals with low HDL-C (men 40 mg/dL. A linear regression model that adjusted for those parameters that impact HDL-C levels (age, gender, waist-to-hip ratio, body mass index, fasting triglyceride concentration, simple sugars, alcohol, physical activity, and omega-3 consumption showed an independent association between tomato consumption and the increase in HDL-C (r2 = 0.69; P > 0.0001. Conclusion: Raw tomato consumption produced a favorable effect on HDL-C levels in overweight women. Keywords: lycopene, hypoalphalipoproteinemia, dyslipidemia, overweight, cardiovascular diseases

    Full Text Available Hormone replacement therapy (HRT reduces cardiovascular risks, although the initiation of therapy may be associated with transient adverse ischemic and thrombotic events. Antibodies against heat shock protein (Hsp and oxidized low density lipoprotein (LDL have been found in atherosclerotic lesions and plasma of patients with coronary artery disease and may play an important role in the pathogenesis of atherosclerosis. The aim of the present study was to assess the effects of HRT on the immune response by measuring plasma levels of antibodies against Hsp 65 and LDL with a low and high degree of copper-mediated oxidative modification of 20 postmenopausal women before and 90 days after receiving orally 0.625 mg equine conjugate estrogen plus 2.5 mg medroxyprogesterone acetate per day. HRT significantly increased antibodies against Hsp 65 (0.316 ± 0.03 vs 0.558 ± 0.11 and against LDL with a low degree of oxidative modification (0.100 ± 0.01 vs 0.217 ± 0.02 (P<0.05 and P<0.001, respectively, ANOVA. The hormone-mediated immune response may trigger an inflammatory response within the vessel wall and potentially increase plaque burden. Whether or not this immune response is temporary or sustained and deleterious requires further investigation.

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

    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.

    Elevated serum triglyceride (TG) and high-density-lipoprotein cholesterol (HDL-C) levels are common in drinkers. The fast-metabolizing alcohol dehydrogenase-1B encoded by the ADH1B*2 allele (vs. ADH1B*1/*1 genotype) and inactive aldehyde dehydrogenase-2 encoded by the ALDH2*2 allele (vs. ALDH2*1/*1 genotype) modify ethanol metabolism and are prevalent (≈90% and ≈40%, respectively) in East Asians. We attempted to evaluate the associations between the ADH1B and ALDH2 genotypes and lipid levels in alcoholics. The population consisted of 1806 Japanese alcoholic men (≥40 years) who had undergone ADH1B and ALDH2 genotyping and whose serum TG, total cholesterol, and HDL-C levels in the fasting state had been measured within 3 days after admission. High serum levels of TG (≥150 mg/dl), HDL-C (>80 mg/dl), and low-density-lipoprotein cholesterol (LDL-C calculated by the Friedewald formula ≥140 mg/dl) were observed in 24.3%, 16.8%, and 15.6%, respectively, of the subjects. Diabetes, cirrhosis, smoking, and body mass index (BMI) affected the serum lipid levels. Multivariate analysis revealed that the presence of the ADH1B*2 allele and the active ALDH2*1/*1 genotype increased the odds ratio (OR; 95% confidence interval) for a high TG level (2.22 [1.67-2.94] and 1.39 [0.99-1.96], respectively), and decreased the OR for a high HDL-C level (0.37 [0.28-0.49] and 0.51 [0.37-0.69], respectively). The presence of the ADH1B*2 allele decreased the OR for a high LDL-C level (0.60 [0.45-0.80]). The ADH1B*2 plus ALDH2*1/*1 combination yielded the highest ORs for high TG levels and lowest OR for a high HDL-C level. The genotype effects were more prominent in relation to the higher levels of TG (≥220 mg/dl) and HDL-C (≥100 mg/dl). The fast-metabolizing ADH1B and active ALDH2, and especially a combination of the two were strongly associated with higher serum TG levels and lower serum HDL-C levels of alcoholics. The fast-metabolizing ADH1B was associated with lower serum LDL

    Full Text Available A 42-day trial was undertaken to study the effect of different dietary levels of thyme essential oil (TEO on serum biochemical indices of broiler chickens. Seven hundred and sixty-eight selected one-day-old Mahua broilers were divided into 8 dietary treatment groups with an addition of 0.00, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30 and 0.35 mg/kg of thyme essential oil respectively, with 4 replicate pens per treatment group (24 birds each. The feeding programme included a starter diet until day 21 and a finisher diet from day 22 until day 42. The results suggested that TEO markedly increased serum total proteins and globulins on day 21, significantly decreased alanine aminotransferase activity (P≤0.05, the albumin- to-globulin ratio, and serum urea on day 21 and 42, and in particular it improved highdensity lipoproteins on day 21 and 42 (P≤0.05. In conclusion, TEO can promote protein metabolism, enhance lipolysis and strengthen the immune function. Furthermore, after a comprehensive analysis, the ideal range of the essential oil addition to the broiler feed proved to be between 0.1 and 0.25 mg/kg.

    The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone), LH (Luteinizing Hormone) and serum prostate specific antigen (PSA) levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations 40 years of age visiting our urology outpatient clinics. PSA was correlated to age (r = 0.23, p = 0.019), but there none between serum testosterone and age. No significant correlation was noted between testosterone or free testosterone and serum PSA levels, and none between serum FSH or LH and PSA. In age specific reference groups (41-49; 50-59; 60-69 years), we found no significant correlation between PSA and hormone concentrations. In this population of eugonadal men with serum PSA values less than 2.5 ng/ml, serum androgens and pituitary hormones do not appear to correlate with serum PSA.

    To review recent advances in the field of remnant lipoproteins and remnant cholesterol with a focus on cardiovascular disease risk. In line with previous years' research, current observational, genetic, and mechanistic studies find remnant lipoproteins (defined in different ways) to be involved in atherosclerosis development and cardiovascular disease risk. High concentrations of remnant cholesterol could explain some of the residual risk of cardiovascular disease seen after LDL cholesterol lowering. This will be increasingly important as populations worldwide become more obese and more have diabetes, both of which elevate remnant cholesterol concentrations. Many smaller scale studies and post hoc analyses show that remnant cholesterol can be lowered by different types of drugs; however, results from large scale studies with the primary aim of reducing cardiovascular disease risk through lowering of remnant cholesterol in individuals with elevated concentrations are still missing, although some are under way. Remnant cholesterol is a risk factor for cardiovascular disease, and can be lowered by different types of drugs; however, large scale studies of cardiovascular disease risk reduction through remnant lipoprotein lowering are under way.

    The International Agency for Research on Cancer has classified diesel engine exhaust (DEE) as a human lung carcinogen. Given that inflammation is suspected to be an important underlying mechanism of lung carcinogenesis, we evaluated the relationship between DEE exposure and the inflammatory response using data from a cross-sectional molecular epidemiology study of 41 diesel engine testing workers and 46 unexposed controls. Repeated personal exposure measurements of PM 2.5 and other DEE constituents were taken for the diesel engine testing workers before blood collection. Serum levels of six inflammatory biomarkers including interleukin (IL)-1, IL-6, IL-8, tumor necrosis factor (TNF)-α, macrophage inflammatory protein (MIP)-1β, and monocyte chemotactic protein (MCP)-1 were analyzed in all subjects. Compared to unexposed controls, concentrations of MIP-1β were significantly reduced by ∼37% in DEE exposed workers (P 397 µg/m 3 ) compared to unexposed controls. Further, significant inverse exposure-response relationships for IL-8 and MCP-1 were also found in relation to increasing PM 2.5 levels among the DEE exposed workers. Given that IL-8, MIP-1β, and MCP-1 are chemokines that play important roles in recruitment of immunocompetent cells for immune defense and tumor cell clearance, the observed lower levels of these markers with increasing PM 2.5 exposure may provide insight into the mechanism by which DEE promotes lung cancer.

    It is generally believed that pregnancy is mediated by a Th2 response, which includes cytokines that promote placental growth and are involved in inducing tolerance to the foetus. If the balance between Th1/and Th2-mediated cytokines is disrupted, systemic and local changes could predispose the foetus to future disease. Therefore, a shift in the Th1/Th2 balance during pregnancy, possibly caused by underlying environmental factors, could be associated with post-partum autoimmune disease in the offspring. Based on this presumption, we used celiac disease as a model to investigate whether autoimmunity is triggered in the foetus during early pregnancy, observed as changes in the mother's cytokine profile. Ten cytokines were measured by electro-chemi-luminescent multiplex ELISA in serum samples obtained from mothers during early pregnancy. Cases included women with children who had developed verified celiac disease before the age of 5, who were compared with other women as matched controls. We observed that 7 out of 10 cytokine levels were significantly increased in our case mothers when compared to controls. Five of these belonged to what is generally known as a Th1-mediated response (TNFα, IFNγ, IL-2, IL-1β and IL-12) and two were Th2 cytokines (IL-13 and IL-10). However, the IL-10 cytokine is known to have features from both arms of the immune system. These results were confirmed in a logistic regression model where five out of the initial seven cytokines remained. This study suggests that increase in Th1 serum cytokines may be associated with celiac disease in offspring.

    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.

    There is inconsistent evidence on a possible association of vitamin D and androgen levels in men. We therefore aim to investigate the association of 25-hydroxyvitamin D (25(OH)D) with androgen levels in a cohort of middle-aged men. This cross-sectional study included 225 men with a median (interquartile range) age of 35 (30-41) years. We measured 25(OH)D, total testosterone (TT) and SHBG concentrations. Hypogonadism was defined as TT hypogonadism was 21.5% and lowest in men within 25(OH)D quintile 4 (82-102 nmol/L). We found a significantly increased risk of hypogonadism in men within the highest 25(OH)D quintile (>102 nmol/L) compared to men in quintile 4 (reference) in crude (OR 5.10, 1.51-17.24, p = 0.009) as well as in multivariate adjusted analysis (OR 9.21, 2.27-37.35, p = 0.002). We found a trend towards increased risk of hypogonadism in men within the lowest 25(OH)D quintile (≤43.9 nmol/L). In conclusion, our data suggest that men with very high 25(OH)D levels (>102 nmol/L) might be at an increased risk of hypogonadism. Furthermore, we observed a trend towards increased risk of hypogonadism in men with very low vitamin D levels indicating a U-shaped association of vitamin D levels and hypogonadism. With respect to risk of male hypogonadism, our results suggest optimal serum 25(OH)D concentrations of 82-102 nmol/L. © 2014 American Society of Andrology and European Academy of Andrology.

    Accumulating evidence suggests that high-density lipoprotein (HDL) cholesterol is associated with pulmonary function and pulmonary disorders. The aim of this study was to evaluate the association between HDL cholesterol and pulmonary function in healthy adolescents. This cross-sectional study was based on data collected for the JS High School study. The analysis included 644 adolescents (318 male and 326 female) aged 15-16 years old and free from asthma or chronic obstructive pulmonary disease. Fasting blood samples were collected for hematologic and biochemical assessment. Forced vital capacity volume (FVC) and forced expiratory volume in the 1 s (FEV1) were measured using dry-rolling-seal spirometry. The associations between HDL cholesterol and pulmonary function were analyzed using multiple linear regression models. Among male adolescents, an increase of 1.0 mg/dL in HDL cholesterol was associated with 10 mL decrease in FVC (p = 0.013) and FEV1 (p = 0.013) after adjusting for age, height, weight, alcohol drinking, smoking, physical activity, systolic blood pressure, total cholesterol, triglyceride, and monthly household income. Percent predicted values of FVC (p = 0.036) and FEV1 (p = 0.017) were also inversely associated with HDL cholesterol. However, among female adolescents, HDL cholesterol level was not significantly associated with absolute or percent predictive value of FVC and FEV1. Higher HDL cholesterol level may be associated with decreased pulmonary function among healthy male adolescents. The sex differences observed in the association between HDL cholesterol and pulmonary function need further investigation.

    Is polycystic ovary syndrome (PCOS) associated with altered levels of pro-inflammatory high-density lipoproteins (HDL) and activity of HDL-associated enzymes? In PCOS, HDL contained increased levels of the inflammatory marker serum amyloid A (SAA) and altered functioning of HDL-associated phospholipid transfer protein (PLTP), with these changes being independent of BMI, body fat and insulin resistance (IR). PCOS is associated with adipocyte-derived inflammation, which potentially increases the risk of cardiovascular disease and diabetes. SAA is an inflammatory marker that is released from hypertrophic adipocytes and interacts with HDL, reducing their anti-atherogenic properties. No studies have previously investigated if SAA-associated HDL influences the HDL-associated enzymes namely, PLTP and cholesterol ester transfer protein (CETP) in women with PCOS. Obese women with PCOS were matched with controls for BMI and percentage body fat (n = 100/group; cohort-1); a subset of these women (n = 64/group; cohort-2) were further matched for IR. HDL in blood samples was subfractionated into HDL₂ and HDL₃ by rapid ultracentrifugation. SAA was measured in serum, HDL₂ and HDL₃ by an enzyme-linked immunosorbent assay and the activities of PLTP and CETP were measured in HDL₂ and HDL₃ by fluorimetric assays. In the PCOS women from cohort-1, SAA was increased in serum, HDL₂ and HDL₃ (P = 0.038, 0.008 and 0.001 versus control, respectively), as was the activity of PLTP in HDL₂ and HDL₃ (P = 0.006 and 0.009 versus controls, respectively). In the PCOS women from cohort-2, SAA was increased in serum, HDL₂ and HDL₃, although only significantly in HDL₃ (P = 0.083, 0.120 and 0.034 versus controls, respectively), as was the activity of PLTP in HDL₂ and HDL₃, although this was only significant in HDL₂ (P = 0.045 and 0.070 versus controls, respectively). First, insulin sensitivity was not determined by the euglycaemic-hyperinsulinaemic clamp. Secondly, the

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

    As part of its research program to study the late effects of radiation in survivors of the atomic bombs, the Atomic Bomb Casualty Commission (ABCC) in conjunction with the Japanese National Institute of Health (JNIH), conducts biennial medical examinations on the selected population which comprises the ABCC-JHIN Adult Health Study sample. The patients herein described as Groups 1 and 2 were selected from among those examined in Nagasaki who had had a hemoglobin value of less than 11.0 g/100 ml at examination 2 years previously and who had responded to iron therapy sufficiently to justify a diagnosis of iron deficiency anemia. Almost all were women of child bearing age. The effect of iron therapy on the level of serum B/sub 12/ was investigated. Of 58 patients so studied, 46 showed some rise in post-treatment levels of B/sub 12/. This is evaluated as indicating that gastric secretion of intrinsic factor is depressed in the majority of iron deficient patients.

  20. The association of serum leptin levels with metabolic diseases

    Full Text Available Leptin is a 167-amino-acid protein released by white adipose tissue and encoded by the obese gene. It has a role as a negative regulator of appetite control through sending a satiety signal to act on receptors within the hypothalamus. At normal levels, leptin can exert its effects on weight regulation according to white fat mass, induce sodium excretion, maintain vascular tone, and repair the myocardium. Beyond these effects, elevated serum leptin levels have been implicated in the pathogenesis of metabolic syndrome, diabetes mellitus, hypertension, and multiple cardiovascular diseases. In addition, hyperleptinemia had been reported to contribute to renal diseases through multiple mechanisms resulting in glomerulopathy presenting with a decreased glomerular filtration rate, increased albuminuria, and related clinical symptoms, which are pathophysiological features of chronic kidney disease. Because these cardiovascular and metabolic disorders are great challenges for physicians, understanding the related pathophysiological association with leptin might become a valuable aid in handling patients in daily clinical practice. This review will discuss the roles of leptin in the regulation of biological functions of multiple organs beyond the maintenance of feeding and metabolism.

    Site-1 protease (S1P) is the key enzyme required for activation of the sterol regulatory element binding proteins (SREBPs) that govern lipid synthesis. While S1P has been speculated to influence plasma apoB-containing lipoprotein (Blp) metabolism, there has been little investigative work. LDL receptor (LDLR) is the major receptor for clearing plasma LDL cholesterol (LDL-c). Proprotein convertase subtilisin kexin type 9 (PCSK9) modulates LDL-c through post-translational degradation of the LDLR. A hepatic-specific knockdown (KD) of S1P was achieved using floxed S1P mouse models (S1P(f/f) and LDLR(-/-)S1P(f/f)) and hepatic expression of Cre recombinase. Lipids were measured in total plasma and size fractionated plasma using colorimetric assays. Realtime polymerase chain reaction, western blotting and ELISA were used to determine hepatic expression of key genes/protein. Plasmid mediated overexpression and siRNA mediated knockdown of genes were performed in mouse primary hepatocytes to determine the mechanistic basis of PCSK9 gene regulation. A hepatic-specific KD of S1P resulted in a 45 % and 38 % reduction in plasma total cholesterol and triglyceride levels, respectively. Hepatic S1P KD had a minimal effect on plasma Blp cholesterol (Blp-c) in S1P(f/f) mice, despite significantly reducing VLDL secretion. Notably, hepatic S1P KD decreased the LDL receptor (LDLR) mRNA expression by 50 %. However, the reduction in LDLR protein levels was less than that of mRNA expression, especially under fed conditions. Further assessment of hepatic S1P deficiency revealed that it increased LDLR protein stability in vivo. Mechanistically, hepatic S1P KD was shown to decrease the liver and plasma levels of the protein proprotein convertase subtilisin/kexin type 9 (PCSK9), which degrades LDLR protein. This effect was more prominent in the fed condition and sufficient to account for the discordance in LDLR mRNA and protein levels. Furthermore, hepatic S1P was shown to regulate PCSK9

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

    Full Text Available Background/Aim. Insulin resistance is related to accelerated atherosclerosis, whereas weight loss is associated with the increasing insulin sensitivity, the improvement of functional and the morphological parameters of arterial circulation, and the reduction of cardiovascular morbidity and mortality. The aim of our study was to evaluate the influence of orlistat treatment on serum insulin level and functional and morphologic parameters of peripheral arterial circulation. Methods. We conducted a prospective, randomized, double − blind, placebo − controlled study. Thirty patients with body mass index over 30 kg/m2 normotensive, nonsmokers, without clinically manifested cardiovascular disease or diabetes were randomly assigned either orlistat (120 mg, 3 times daily; n = 20 or placebo (n = 10 in a double − blind manner. All of the patients were on individually calculated hypocaloric diet. The follow-up period was 24 weeks. Arterial pressure, fasting serum glucose and insulin level, triglycerides, total cholesterol and low density lipoprotein-cholesterol were determined at the beginning, following 3 and 6 months. Also, the intima − media thickness of right superficial femoral artery and the mean blood flow velocity were determined with ultrasonography. Results. Inside the period of 3 and 6 months, there were the greater reductions of body mass index, arterial pressure, fasting glucose and insulin level, total cholesterol, low density lipoproteins, as well as the greater reductions of mean velocity blood flow and peripheral pulse pressure in the orlistat group vs the placebo group (p < 0.01. Greater reductions in the waist circumference and intima − media thickness were registered following 6 months in the orlistat vs the placebo group (p < 0.01. Conclusion. In the group of obese patients orlistat therapy reduced risk factors, serum insulin level and improved early arterial functional changes as assessed with the reductions of the mean

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

    Our aim was to assess serum levels of the soluble receptor for advanced glycation end products (sRAGE) and to examine their association with anthropometric and metabolic parameters in patients with prediabetes and obese controls. The two study groups were composed of 42 patients with prediabetes and diabetic neuropathy and 42 age-, gender-, body weight (BW)-, and body mass index (BMI)-matched obese adults as the control group. Prediabetes was diagnosed by the following criteria issued by the American Diabetes Association: impaired fasting glucose [fasting plasma glucose (FPG) level of 100-125 mg/dL], impaired glucose tolerance (2 hr plasma glucose level of 140-199 mg/dL after a 75 grams oral glucose challenge), or a glycated hemoglobin (HbA1C) level of 5.7%-6.4%. There were no differences between the groups in terms of age, gender distribution, BW, or BMI. Despite these similarities, patients with prediabetes had higher FPG, HbA1c, and 2-hr postchallenge glucose levels, higher systolic and diastolic blood pressure, and larger waist and hip circumferences compared with the obese controls. Lipid measurements, complete blood counts, kidney and liver function tests, high-sensitivity C-reactive protein, and sRAGE levels were similar between the two groups. We found significant negative correlations between sRAGE levels and BW, BMI, waist and hip circumferences, waist-to-hip ratios, and low-density lipoprotein (LDL) cholesterol levels. There were no significant correlations with other parameters, including demographic, metabolic, and blood pressure measurements. In contrast to glycemic parameters, serum levels of sRAGE were negatively correlated with body measurements indicative of obesity in the prediabetic state. In addition, the negative correlation with LDL cholesterol levels suggests that sRAGE has a more robust association with metabolic syndrome than with prediabetes.

    The aim of this study was to investigate the possible correlation between levels of serum liver enzymes and impaired fasting glucose (IFG) in Chinese adults and to provide a new perspective for the prevention of pre-diabetes. Serum liver enzymes of the samples including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and g-glutamyl transferase (GGT), as well as plasma glucose, blood lipids, and insulin, were measured. The cumulative incidences of IFG between different quartiles of liver enzymes were compared by the chi-square test. A logistic regression model (binary regression) was used to calculate the odds ratio (OR) of IFG with 95% confidence interval (95% CI). The total incidence of IFG was 20.3% and the cumulative incidence of IFG was higher in men compared to women. In both sexes, IFG is more prevalent in higher quartiles of liver enzymes. After adjusting for age, BMI, blood pressure, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC), the cumulative incidences of IFG were significantly higher in the highest quartiles of liver enzymes than in the lowest quartiles. A significantly higher cumulative incidence of IFG was found in the highest GGT quartile than in the lowest quartile for woman. The results of this study suggest that serum liver enzymes are related to the risk of IFG in Chinese adults. We infer that preserving the hepatic function may be an efficient way to prevent the development of IFG, especially in males.

    Recent studies have demonstrated an association between serum uric acid (SUA) levels and metabolic syndrome (MetS). However, paucity of available data regarding the cause and effect relationship between SUA and MetS in healthy adults is still a big challenge which remains to be studied. Therefore, we investigated whether SUA predicts new onset of MetS in a population-based cohort study. The study included 1590 adults (661 men and 929 women) aged 40-70 years without MetS at baseline (2005-2008) and subjects were prospectively followed for 2.6 years. To evaluate the relationship between SUA and MetS, we divided the aforementioned subjects into quintiles (SUA-I to SUA-V) from the lowest to the highest values of SUA. SUA was measured by the enzymatic colorimetric method. We used category-free net reclassification improvement (NRI) and integrated discrimination improvement (IDI) to characterize the performance of predicted model. During a mean of 2.6 years of follow-up, 261(16.4%) adults developed MetS. MetS variables were significantly related to the baseline SUA level. Waist circumference (WC), blood pressure (BP), and serum triglyceride (TG) were significantly higher in the highest quintile of SUA compared to the lowest SUA quintile in men and women. After adjustment for age, total cholesterol and low-density lipoprotein cholesterol (LDL-C) in men and women, subjects in the fifth quintiles of SUA showed significantly higher ORs for incident MetS. The association between hyperuricemia and new onset of MetS were consistently stronger in women than men. Additionally, among women, we found an improvement in the area under the ROC curve in the models that added SUA to core components of MetS. Our study suggests that SUA is significantly correlated with future risk of WC, BP, TG and may predicted as a risk factor for developing MetS. SUA may have a clinical role in predicting new-onset metabolic syndrome among women. Large prospective study is needed to reveal the clinical

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

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

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

    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.
