    Objective. To assess serum level of Dickkopf-1 in postmenopausal females and its correlation with bone mineral density and serum biochemical markers. Methods. Bone densitometry, serum Dickkopf-1, calcium, phosphorus, and alkaline phosphatase were done in sixty postmenopausal females. Patients were divided according to T score into osteoporosis (group I), osteopenia (group II), and normal bone mineral density that served as controls. Results. There was highly significant increase in serum Dickkopf-1 levels in postmenopausal females with abnormal T score versus controls (P < 0.001). Serum DKK-1 levels correlated negatively with both lumbar T score (r = −0.69, P < 0.001) and femur T score (r = −0.64, P < 0.001) and correlated positively with duration of menopause (r = 0.61, P < 0.001), while there was no significant correlation between serum levels of either calcium, phosphorus or alkaline phosphatase, and both serum Dickkopf-1 levels and the level of bone mineral density (P > 0.05). Conclusion. Postmenopausal females may suffer from osteoporosis as evidenced by bone densitometry. Postmenopausal women with significantly increased serum Dickkopf-1 had more significant osteoporosis. Prolonged duration of menopause and increased serum Dickkopf-1 are important risk factors for the development and severity of osteoporosis. PMID:23878759

    Calcium, magnesium, potassium, sodium, chloride and phosphorus are the major dietary minerals involved in various biological functions and are commonly measured in the blood serum. Sufficient mineral intake is especially important for children due to their rapid growth. Currently, the genetic mechanisms influencing serum mineral levels are poorly understood, especially for children. We carried out a genome-wide association (GWA) study on 5,602 European-American children and 4,706 African-American children who had mineral measures available in their electronic medical records (EMR). While no locus met the criteria for genome-wide significant association, our results demonstrated a nominal association of total serum calcium levels with a missense variant in the calcium -sensing receptor (CASR) gene on 3q13 (rs1801725, P = 1.96 × 10(-3)) in the African-American pediatric cohort, a locus previously reported in Caucasians. We also confirmed the association result in our pediatric European-American cohort (P = 1.38 × 10(-4)). We further replicated two other loci associated with serum calcium levels in the European-American cohort (rs780094, GCKR, P = 4.26 × 10(-3); rs10491003, GATA3, P = 0.02). In addition, we replicated a previously reported locus on 1q21, demonstrating association of serum magnesium levels with MUC1 (rs4072037, P = 2.04 × 10(-6)). Moreover, in an extended gene-based association analysis we uncovered evidence for association of calcium levels with the previously reported gene locus DGKD in both European-American children and African-American children. Taken together, our results support a role for CASR and DGKD mediated calcium regulation in both African-American and European-American children, and corroborate the association of calcium levels with GCKR and GATA3, and the association of magnesium levels with MUC1 in the European-American children.

    The effects of long-term running exercise were studied in 20 beagle dogs. A total of 10 dogs ran from the age of 15 weeks to the age of 70 weeks in a progressive program for up to 40 km/day. A total of 10 sister dogs spent the study period in individual cages. When the dogs were 70 weeks old, bone mineral density of the vertebrae, hip, and radius was analyzed by dual-energy x-ray absorptiometry (DEXA; Lunar) and the vertebrae were also assessed by quantitative computed tomography (QCT; Siemens DR 1). Mineral density was lower in the running dogs than in the controls. The difference was greatest in the spine in the QCT analysis. Blood chemistry analyses revealed that the metabolism of the bone was significantly accelerated. The estradiol levels showed the trend to be reduced in the running group. The beneficial effect of exercise on mineral density has been shown in many earlier studies. However, in this study we demonstrate the possibility of adverse effects of long-term exercise on bone tissue. The change was associated with a decrease of serum estradiol level. PMID:1414479

    Patients with fibromyalgia syndrome (FMS) have impaired mobility and therefore get less sunlight exposure, we postulated that they may be at increased risk of developing osteoporosis (OP). The aim of this study was to assess and compare serum vitamin D level and bone mineral density (BMD) value in patients with primary FMS (PFMS) and healthy controls. A total of 50 patients with PFMS participated in this case-control study, and 50 healthy females who were age-matched to the patients were used as the control group. Venous blood samples collected from all subjects were used to evaluate serum 25-hydroxyvitamin D3 (25-OHD). BMD was measured at the lumbar spine (L2-L4) anteroposterior, femoral neck and forearm by dual-energy X-ray absorptiometry. Patients with PFMS had significantly lower serum 25-OHD than controls (15.1 ± 6.1 and 18.8 ± 5.4 ng/ml, respectively, p = 0.0018). Apart from the BMD in the lumbar spine, which was significantly lower in the PFMS patients compared with controls (p = 0.0012), no significant difference was found in other measures of BMD. Compared to PFMS patients who had serum level of the 25-OHD >20 ng/ml, the patients with 25-OHD ≤20 ng/ml are more likely to have impaired short memory (46.4 vs. 13.6%, respectively, p = 0.0136), confusion (50 vs. 18.2%, respectively, p = 0.0199), mood disturbance (60.7 vs. 27.3%, respectively, p = 0.0185), sleep disturbance (53.6 vs. 22.7%, respectively, p = 0.0271), restless leg syndrome (57.1 vs. 27.3%, respectively, p = 0.0346) and palpitation (67.9 vs. 36.4%, respectively, p = 0.0265). Serum level of the 25-OHD is inversely correlated with visual analogue scale (VAS) of pain (p = 0.016), Beck score for depression (p = 0.020) and BMD at lumbar spine (p = 0.012). The lumbar BMD inversely correlated with VAS of pain (p = 0.013) and Beck score for depression (p = 0.016). This study confirmed high prevalence of hypovitaminosis D among in patients with PFMS. This study confirmed the concept that FMS is a risk

    Serum vitamin D (25-hydroxyvitamin D (25OHD)) may influence serum parathyroid hormone (PTH) levels and bone mineral density (BMD). In the present study, we assessed serum 25OHD concentration and its association with PTH and BMD in urban males from Guiyang (N26.57°), the capital city of Guizhou province, Southwest China. We recruited 634 males aged >20 years from the Guiyang Health Measures Survey, and stratified them into three groups according to age: young (20-39 years), middle aged (40-59 years) and older (60-79 years). We measured serum concentrations of 25OHD, PTH levels and BMD of the lumbar spine (L1-L4), femoral neck and total hip. In addition, we also explored the relationship between 25OHD and lifestyle, socio-economic characteristics and medical history by applying covariance analysis and locally weighted regression plots. The results showed that serum 25OHD was 75 nmol/l in 12·6 % of the subjects. Higher level of serum PTH was detected in relation to lower concentrations of serum 25OHD up to 50 nmol/l. A negative correlation between serum 25OHD and PTH concentrations was observed (r -0·207, P=0·003). Mean concentration of serum PTH increased gradually and plateaued while concentrations of serum 25OHD decreased to 50 nmol/l. Gradual increase in serum PTH was observed as 25OHD concentration was <25 nmol/l (P=0·004). BMD values at all sites were greater in the higher serum 25OHD concentration group. This study shows that low concentrations of serum 25OHD were common in males, and bone health was likely to be improved when serum 25OHD values were between 30 and 50 nmol/l. PMID:26843386

  6. High Levels of Serum DPP-4 Activity Are Associated with Low Bone Mineral Density in Obese Postmenopausal Women

    2016-01-01

    Background Dipeptidyl peptidase 4/CD26 (DPP-4) is a widely expressed cell surface serine protease. DPP-4 inhibitors, one of common anti-diabetic agents play a protective role in bone metabolism in recent studies. A soluble form of DPP-4 is found in serum, and exhibits DPP-4 enzymatic activity. However, the physiological role of serum or soluble DPP-4 and its relationship with DPP-4 enzymatic function remain poorly understood. The aims of current study were to determine the association between serum DPP-4 activity and bone mineral density (BMD) in postmenopausal women. Methods We recruited data and serum samples from 124 consecutive healthy postmenopausal women aged >50 years. We divided study subjects into obese (body mass index [BMI] ≥25 kg/m2) and non-obese (BMI <25 kg/m2) postmenopausal women and examined the correlation between serum DPP-4 activity and clinical variables in each groups. Results A total of 124 postmenopausal women was enrolled, with a mean age of 59.9±7.1 years. The mean BMI of the study patients was 24.4±2.8 kg/m2. Regarding bone turnover markers, serum DPP-4 activity was positively correlated with serum calcium concentrations, intact parathyroid hormone, and serum C-telopeptide levels in all of the study subjects. However, there was no association between serum DPP-4 activity and BMD in the spine or femoral neck in all of the study subjects. Serum DPP-4 activity was negatively correlated (R=−0.288, P=0.038) with BMD of the spine in obese postmenopausal women. Conclusion This study demonstrated for the first time that serum soluble DPP-4 activity was negatively correlated with BMD in obese postmenopausal women. PMID:26676330

    We investigated effects of multivitamin/mineral supplementation on element levels in serum and follicular fluid of women undergoing IVF. We used three groups in this study. The first group was used as an age-matched and nonpregnant control (n = 13). Group 2 (n = 30) constituted the IVF group and women in the third group who were undergoing IVF also received a multivitamin/mineral tablet daily for 45 days. Follicular fluid and serum selenium and zinc levels and follicular fluid copper levels were lower in IVF patients than in controls although follicular fluid aluminum and iron levels were higher in IVF patients than in controls. However, follicular fluid and serum aluminum, copper, zinc and selenium levels, and serum magnesium levels were higher in the multivitamin/mineral group than in the IVF group although follicular fluid iron levels were lower in the multivitamin/mineral group than in the IVF group. In conclusion, we observed that copper, zinc, and selenium in serum and follicular fluid decreased in women undergoing IVF. Multivitamin/mineral supplementation in serum and follicular fluid of women undergoing IVF normalized the trace element levels. PMID:20180042

    Growth differentiation factor 11 (GDF11) is an important circulating factor that regulates aging. However, the role of GDF11 in bone metabolism remains unclear. The present study was undertaken to investigate the relationship between serum GDF11 level, bone mass, and bone turnover markers in postmenopausal Chinese women. Serum GDF11 level, bone turnover biochemical markers, and bone mineral density (BMD) were determined in 169 postmenopausal Chinese women (47–78 years old). GDF11 serum levels increased with aging. There were negative correlations between GDF11 and BMD at the various skeletal sites. After adjusting for age and body mass index (BMI), the correlations remained statistically significant. In the multiple linear stepwise regression analysis, age or years since menopause, BMI, GDF11, and estradiol were independent predictors of BMD. A significant negative correlation between GDF11 and bone alkaline phosphatase (BAP) was identified and remained significant after adjusting for age and BMI. No significant correlation was noted between cross-linked N-telopeptides of type I collagen (NTX) and GDF11. In conclusion, GDF11 is an independent negative predictor of BMD and correlates with a biomarker of bone formation, BAP, in postmenopausal Chinese women. GDF11 potentially exerts a negative effect on bone mass by regulating bone formation. PMID:27408764

    A reduced bone mineral density (BMD) is observed in several rheumatic autoimmune diseases, including Systemic Sclerosis (SSc); nevertheless, data concerning the possible determinants of bone loss in this disease are not fully investigated. The aim of this study is to evaluate the relationship between BMD, body mass composition, skin sclerosis and serum Vitamin D levels in two subsets of SSc patients. 64 post-menopausal SSc patients, classified as limited cutaneous (lcSSc) or diffuse cutaneous (dcSSc) SSc, were studied. As control, 35 healthy post-menopausal women were recruited. Clinical parameters were evaluated, including the extent of skin involvement. BMD at lumbar spine, hip, femoral neck and body mass composition were determined by dual-energy X-ray absorptiometry. Serum calcium, phosphorus, alkaline phosphatase, urine pyridinium cross-links, intact parathyroid hormone and 25-hydroxyvitamin D (25OHD) were measured. BMD at spine, femoral neck and total hip was significantly lower in SSc patients compared to controls. In dcSSc subset, BMD at spine, femoral neck and total hip was significantly lower compared to lcSSc. No differences in both fat and lean mass were found in the three study groups even if patients with dcSSc showed a slightly lower total body mass compared to healthy controls. Total mineral content was significantly reduced in dSSc compared to both healthy subjects and lcSSc group. Hypovitaminosis D was observed both in healthy post-menopausal women and in SSc patients, but 25OHD levels were significantly lower in dcSSc compared to lcSSc and inversely correlated with the extent of skin thickness. These results support the hypothesis that the extent of skin involvement in SSc patients could be an important factor in determining low circulating levels of 25OHD, which in turn could play a significant role in the reduction of BMD and total mineral content.

    To investigate the association of serum semaphorin 4D (Sema4D) levels with lumbar spine bone mineral density (BMD) and bone turnover markers in patients with postmenopausal osteoporosis (PO). Lumbar spine BMD was measured by dual-energy X-ray absorptiometry in 257 PO patients (aged from 50 to 75) and 90 healthy controls (aged from 51 to 83). Serum Sema4D, BAP, BGP and TRACP-5b levels were measured by enzyme linked immunosorbent assay. Serum cross linked N-telopeptides of type I (NTX), 25-hydroxyvitamin D (25(OH)D) and N-mid fragment of osteocalcin (N-MID-OT) levels were measured using automated electrochemiluminescence system. Sema4D level was significantly higher in PO women compared to healthy controls (1.40±0.33 vs. 0.58±0.18 μg/L, P=0.006). Sema4D level was positively correlated with serumTRACP-5b and NTX levels and negatively correlated with lumbar spine BMD and serum BAP and BGP levels. There were no correlations between Sema4D level and age, body mass index, and serum 25(OH)D and N-MID-OT levels. Lumbar spine BMD (β=-0.354, P<0.001) and serum BAP level (β=0.127, P=0.019) were independent predictors of serum Sema4D level in PO patients. Sema4D may be involved in the pathogenesis of PO and play a critical role in bone formation and resorption. Sema4D may represent a novel therapeutic target for treatment of PO and function as a predictive indicator of PO. PMID:26629156

    A possible negative effect of iron overload on bone metabolism has been suggested by the fact that patients with hemochromatosis, thalassemia, and sickle cell anemia have lower bone mineral density than the general population. However, the influence of iron overload on bone health in the general population is uncertain. The aim of this study was to investigate the relationship between serum ferritin levels and bone mineral density (BMD) in elderly Koreans. A total of 2,943 subjects aged 65 years and over who participated in the 2008-2010 Korea National Health and Nutrition Examination Surveys were included in this study. Age, physical activity, current smoking status, alcohol consumption, education level, household income, and dietary assessment were surveyed by a face-to-face interview. BMD was measured at the lumbar spine and femur by dual-energy X-ray absorptiometry, and other biochemical markers, including serum ferritin, 25-hydroxyvitamin D3, serum alkaline phosphatase, and parathyroid hormone, were assayed. After adjusting for age and body mass index, we found an association between BMD of the total lumbar spine, total femur, and femur neck and levels of alkaline phosphatase, parathyroid hormone, vitamin D3, and daily intake of calcium and protein. Serum ferritin levels were positively associated with BMD of the total lumbar spine, total femur, and femur neck after adjusting for all covariates in men, but not in women. This study suggests a positive association between serum ferritin levels and BMD in elderly South Korean men without hematologic disorders. Further study is warranted to verify the effects of iron on bone metabolism. PMID:24337956

    Nutrition plays a role in the etiology of osteoporosis. Two of the most important nutrients for bone health are calcium and vitamin D. Plasma 25-hydroxyvitamin D [25-(OH)D] is the most sensitive clinical index of vitamin D status and has been found to be positively related to bone mineral density (BMD) in middle-aged and elderly women, and positive relations exist between the BMD of adult women and their calcium consumption throughout life. The aim of the present study was to determine relationships between BMD, serum vitamin D levels and dietary calcium intake of female young adult students who dressed in different styles. We studied two groups of volunteer female students (total = 67). Students in the first group dressed in a style that exposed the skin to sunlight, students in the second group wore dresses completely covering the skin except for the face and hands. Serum 25-(OH)D levels were measured by radioimmunoassay, BMDs were determined at the lumbar spine and femoral neck by dual-energy X-ray absorptiometry, and calcium intakes were estimated with a 3-day food recording questionnaire. The serum 25-(OH)D level was significantly lower in the second group. There was no significant difference in BMD between the two groups. The dietary calcium intake of the two groups were lower than the adequate intake of 1000 mg daily for this age. There was a correlation between the serum 25-(OH)D level and BMD at the femoral neck in the first group. Our results indicate that vitamin D and calcium requirements for normal bone mineral accrual in young adults may advance until a certain age, and the covered dressing style causes vitamin D insufficiency and most of the students were under risk for osteoporosis in later life.

    Background & objectives: Phosphorylated heat shock protein 27 (pHSP27) has been implicated in the pathogenesis of osteoporosis. Oxidative stress and proinflammatory cytokines, which are known to be involved in aetiology of osteoporosis, can trigger HSP27 phosphorylation. Since pHSP27 is present in circulation, it was hypothesized that serum pHSP27 would be elevated in low bone mineral density (BMD) condition and might serve as an indicator of osteoporosis/osteopenia. Hence, the aim of this study was to examine serum levels of pHSP27 in relation with BMD in pre- and postmenopausal women. Methods: Premenopausal (30 to 40 yr) and postmenopausal (50 to 60 yr) women having either low BMD (osteopenia/osteoporosis) or high BMD were selected (n=80) from a prospective cohort (n=200). Serum levels of pHSP27; along with levels of oestradiol, malondialdehyde, total antioxidant capacity, interleukin (IL)-1, IL-6, tumour necrosis factor - alpha, (TNF-α), c-telopeptide fragments of collagen type I (CTX-1) and osteocalcin were estimated. Results: The serum levels of pHSP27 were significantly elevated in low BMD groups in premenopausal and postmenopausal categories (P<0.05). It also exhibited a significant odds ratio (OR) to differentiate between low and high BMD in both premenopausal (OR=1.734, P=0.013) and postmenopausal (OR=1.463, P=0.042) categories. Additionally, area under the curve to predict low BMD was non-significantly higher for pHSP27 than CTX-1 in premenopausal and postmenopausal categories. Interpretation & conclusions: This study highlights a novel relation between serum pHSP27 and BMD in Indian women however, these findings need to be confirmed in larger studies. PMID:27241641

    We examined the relationships existing between serum cytokine levels and bone mineral density (BMD) in women of premenopausal age affected by Graves' disease with subclinical hyperthyroidism. The study population consisted of 21 women with untreated hyperthyroid Graves' disease (group H) (age, 36 +/- 2 years), eight women with untreated subclinical hyperthyroid status (group SH) (age, 33 +/- 5 years) and 10 healthy women (group N) (age, 35 +/- 3 years). The following measurements were made in all patients: free T4 (fT4), free T3 (fT3), thyroid stimulating hormone (TSH), TSH receptor antibody (TRab), anti-thyroid peroxidase antibody (anti-TPO), anti-thyroglobulin antibody (anti-Tg), interleukin-2 receptor (IL-2r), interleukin-4 (IL-4), interleukin-8 (IL-8) and interleukin-13 (IL-13). IL-2r and IL-8 levels significantly increased in group H compared with group SH (p < 0.01 and p = 0.05, respectively) and group N (p < 0.001 and p = 0.02, respectively). IL-4 and IL-13 levels tended to be lower in groups H and SH compared with group N, although this difference did not reach statistical significance. Bone mineral density was significantly reduced in only two areas of the femur in group H compared with group N. There was no difference in BMD between groups SH and N. There was no correlation between thyroid hormones, serum cytokine levels and BMD in either group. In conclusion, these results suggest that there were no relationships existing between the serum level of these cytokines and BMD in women of premenopausal age affected by Graves' disease with subclinical hyperthyroidism.

    In astronauts and cosmonauts, exposure to microgravity has been associated with several physiological changes, including an osteoporosis like loss of bone mass. It has been reported that head-down tilt bed-rest studies mimic many of the observations seen in space flights. There has been no study of the effects of mandibular bone and alveolar bone loss in both sexes under conditions of simulated microgravity. This study was designed to investigate bone mineral density; bone mineral content; matrix metalloproteinase (MMP)-8, MMP-9, cathepsin K, and osteocalcin levels in gingival crevicular fluid (GCF); and salivary and serum osteocalcin levels in normal healthy men and women under conditions of simulated microgravity, namely, -6° head-down-tilt (HDT) bed rest. The subjects of this investigation were 10 male and 10 female volunteers who were exposed to 3 weeks of -6° HDT bed rest. Dual-energy X-ray absorptiometry was used to measure bone density and bone mineral content in alveolar bone from the mandibular canine to the third molar, as well as in the mandibular ramus, before, during, and after exposure to conditions of simulated microgravity. GCF (ie, MMP-8, MMP-9, cathepsin K, and osteocalcin) and salivary and serum osteocalcin levels were measured by enzyme-linked immunosorbent assays. Bone mineral density and bone mineral content were significantly lower under conditions of simulated microgravity in both sexes. The decreases were greater in women than in men, but the differences between sexes were not significant. Cathepsin, osteocalcin, MMP-8, and MMP-9 levels were significantly higher under conditions of simulated microgravity than under normal conditions; the increases were greater in women than in men, but the differences were not significant. Additional, more comprehensive, studies with larger sample sizes are now necessary for the investigation of simulated microgravity and microgravity. PMID:20881330

    Background Chronic metabolic acidosis leads to bone mineral loss and results in lower bone mineral density (BMD), which is a risk factor for osteoporosis-related fractures. The effect of low-level metabolic acidosis on bone density in the general population is unknown. Study Design Cross-sectional study. Setting & Participants 9,724 nationally representative adults aged 20 years or older in the National Health and Nutrition Examination Survey 1999-2004. Factor Serum bicarbonate level. Outcomes Lumbar and total BMD as well as low lumbar and total bone mass defined as 1.0 SD below sex-specific mean of young adults. Measurements BMD was measured by dual-energy X-ray absorptiometry and serum bicarbonate levels were measured in all participants. Results Both men and women with lower serum bicarbonate levels were more likely to be current smokers and had higher body mass index and estimated net endogenous acid production. There was a significant linear trend across quartiles of serum bicarbonate with lumbar BMD among the total population as well as in sex-specific models (p=0.02 for all three models, p=0.1 for interaction). For total BMD, a significant association was seen with serum bicarbonate levels among women but not men (p=0.02 and p=0.1, respectively; p=0.8 for interaction); and a significant association was seen among post-menopausal women but not pre-menopausal women (p=0.02 and p=0.2, respectively; p=0.5 for interaction). Compared to women with serum bicarbonate level <24 mEq/L, those with serum bicarbonate ≥27 mEq/L had 0.018 g/cm2 higher total BMD (95% CI, 0.004-0.032; p=0.01) and had 31% lower odds of having low total bone mass (OR, 0.68; 95% CI, 0.46-0.99; p=0.05). Limitations Cross-sectional study using a single measurement of serum bicarbonate level. The subgroup differences are not definitive. Conclusions Lower serum bicarbonate levels are associated with lower BMD in US adults. Further studies should examine whether serum bicarbonate levels should be

    The aim of the current study was to examine the relationship between Cdx-2 polymorphism in the promoter region of the VDR gene and serum 25-hydroxyvitamin D (25(OH)D) levels, bone mineral density (BMD) and fracture in Chinese population. This was a cross-sectional study, which included 738 individuals (428 women and 310 men) aged 45 years or older. In women, the association of Cdx-2 polymorphism with serum 25(OH)D levels was significant adjusting for age, BMI, estimated glomerular filtration rate, menopausal status and season of blood collection (P = 0.002). Cdx-2 polymorphism was associated with lumbar spine BMD adjusted for age, BMI, menopausal status and serum 25(OH)D in women (P = 0.005). But it was not associated with femoral neck BMD or total hip BMD in women. In women, Cdx-2 polymorphism was also associated with fracture adjusted for age, BMI, menopausal status, serum 25(OH)D and total hip BMD (P = 0.03). Carriers of AA and AG genotypes was associated with a higher odds of fracture compared with the carriers of GG genotype (OR = 2.14, 95% CI 1.04-4.42 and OR = 1.90, 95% CI 1.03-3.51). In men, Cdx-2 polymorphism was not associated with serum 25(OH)D levels, BMD or fracture. Our results indicate that the association of Cdx-2 polymorphism in the VDR gene with serum 25(OH)D levels, BMD and fracture may have sex differences. Cdx-2 polymorphism in the VDR gene may affect the serum 25(OH)D concentrations and the risk of osteoporosis and fracture in middle-aged and elderly Chinese women. PMID:26970179

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

    Health surveillance of workers exposed to fibrogenic agents ideally should identify individuals at risk or detect pulmonary fibrosis in preclinical stages. We investigated serum procollagen type III N-terminal peptide (PIIIP) in several groups of active miners and in a nondust-exposed control group. The purpose of this study was to determine the applicability of PIIIP as an early noninvasive marker of pulmonary fibrosis in workers exposed to coal mine dust. PIIIP levels were significantly elevated in miners without radiological signs of coal workers pneumoconiosis (CWP) as compared with the nonexposed controls. However, in coal miners with CWP beyond ILO classification 1/0, PIIIP levels were not significantly different from nondust-exposed controls. Trend analysis within the miners group indicated a decrease in PIIIP levels with progression of the fibrosis. Our data suggest that detection of early lung fibrosis by measuring serum PIIIP values may be more sensitive than radiological diagnosis of CWP. However, follow-up of the control miners with respect to serum PIIIP and chest radiography is essential to validate PIIIP as a biological marker for CWP. PMID:1572317

    The ampicillin levels in sputum, serum, and saliva from 40 patients receiving a dose of 250 mg., 26 patients receiving a dose of 500 mg., and 11 patients receiving a dose of 1 g. were estimated. The ampicillin was given orally four times daily. The 1-2 hour and 2-3 hour sputum levels were similar in individual patients. There was no difference in the range or mean sputum or saliva levels between specimens from patients receiving 250 mg. and 500 mg., but the levels were significantly higher after the 1 g. dose. The mean serum level showed a small increase after 500 mg. ampicillin as compared with the 250 mg. dose and a big increase after the 1 g. dose: only the latter difference was significant. The sputum levels were approximately 30 to 40 times lower than the corresponding serum levels. There was considerable scatter in the sputum level for any level of ampicillin in the serum: in only two of the 1-2 hour sputum specimens was there no detectable ampicillin. There was no correlation between the sputum levels and either the body weight or the dose in milligrams per kilogram. There was no evidence that corticosteroids or diuretics affected the sputum level. It was not possible to demonstrate any relationship between the purulence of the sputum and the level of ampicillin after doses of 250 mg. or 500 mg., but higher levels were found in the more purulent specimens after 1 g. doses.

    Serum estradiol levels were compared in smoking and nonsmoking men in two separate samples. Sample I consisted of 41 young adult male volunteers ranging in age from 18 to 24 years. Twenty-three men smoked an average of 24.5 +/- 6.9 cigarettes daily. The duration of smoking averaged 5.2 +/- 2.2 years. Sample II consisted of 35 husbands who had been evaluated for infertility; they ranged in age from 19 to 49 years. Eighteen men smoked an average of 21.6 +/- 7.9 cigarettes daily. The duration of smoking averaged 11.5 +/- 4.5 years. Age, height, and weight did not differ significantly between smokers and nonsmokers within either group. Serum estradiol levels were significantly elevated in smokers compared with nonsmokers in both groups (p less than 0.001 and p less than 0.0001 in Samples I and II, respectively). No significant correlations were found between serum estradiol levels and the number of cigarettes smoked daily, or with the duration of smoking in either sample. The differences in serum estradiol levels between smokers and nonsmokers could not be attributed to the differences in marijuana and alcohol use that existed between the smokers and nonsmokers in each sample. The recent reports of elevated serum estradiol levels as a possible risk factor in coronary heart disease are discussed in view of the known relationship of cigarette smoking to coronary heart disease.

    Subfertility is a major reproductive health problem all over the world as well as Bangladesh, and the problem is increasing day by day. This study was done to estimate the serum prolactin concentration in primary and secondary subfertile women. Laboratory investigation included serum prolactin level, as well as LH, FSH, TSH blood glucose (2 hours after 75 gm glucose load) of 50 women who attended infertility unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from March 2009 and February 2010. In most cases, common age group 26-30 years (52%), primary subfertility (74%), duration of marriage >5 years (60%), trying to conceive duration ≤5 years (54%), BMI >25 kg/m² (60%), menstrual cycle regular (58%), history of abortion absent (90%), and history of menstrual regulation absent (94%). Common investigation findings was normal serum follicle stimulating hormone (FSH) 1.0-10.0 mIU/ml in 82%, normal serum luteinizing hormone (LH) 1.0-10.0 mIU/ml in 50%, normal serum prolactin 1.9-25.0 ng/ml in 36%, normal serum thyroid stimulating hormone (TSH) 0.4-4.0 μIU/ml in 56%, and normal blood glucose level (2 hours after breakfast) (<7.8 mmol/) in 66% women. Ultrasonographic finding of lower abdomen was normal in 14% women. Common finding of semen analysis husbands of the study women was normozoospermia in 88% cases. Serum prolactin concentration may have role to play in subfertility of women. PMID:26931256

    Some forms of estrogen are associated with breast cancer risk as well as with mammographic density (MD), a strong marker of breast cancer risk. Whether phytoestrogen intake affects breast density, however, remains unclear. We evaluated the association between serum levels of phytoestrogens and MD in postmenopausal women. We enrolled 269 women, ages 55-70 yr, who received a screening mammogram and had no history of postmenopausal hormone use. Subjects completed a survey on diet and factors related to MD and provided a blood sample for analysis of 3 phytoestrogens: genistein, daidzein, and coumestrol. We examined whether mean percent MD was related to serum level of phytoestrogens, adjusting for age and body mass index. Genistein and daidzein levels correlated with self-reported soy consumption. Mean percent MD did not differ across women with different phytoestrogen levels. For example, women with nondetectable genistein levels had mean density of 11.0% [95% confidence intervals (CI) = 9.9-12.4], compared to 10.5% (95% CI = 8.0-13.7) and 11.2% (95% CI = 8.7-14.6) for < and ≥ median detectable levels, respectively. In a population with relatively low soy intake, serum phytoestrogens were not associated with mammographic density. Additional studies are needed to determine effects of higher levels, particularly given patterns of increasing phytoestrogen intake. PMID:22860715

    Fibroblast growth factor 23 (FGF23) circulates as active protein and inactive fragments. Low iron status increases FGF23 gene expression, and iron deficiency is common. We hypothesized that in healthy premenopausal women, serum iron influences C-terminal and intact FGF23 concentrations, and that iron and FGF23 associate with bone mineral density (BMD). Serum iron, iron binding capacity, percent iron saturation, phosphorus, and other biochemistries were measured in stored fasting samples from healthy premenopausal white (n=1898) and black women (n=994), age 20-55years. Serum C-terminal and intact FGF23 were measured in a subset (1631 white and 296 black women). BMD was measured at the lumbar spine and femur neck. Serum phosphorus, calcium, alkaline phosphatase and creatinine were lower in white women than black women (p<0.001). Serum iron (p<0.0001) and intact FGF23 (p<0.01) were higher in white women. C-terminal FGF23 did not differ between races. Phosphorus correlated with intact FGF23 (white women, r=0.120, p<0.0001; black women r=0.163, p<0.01). However, phosphorus correlated with C-terminal FGF23 only in black women (r=0.157, p<0.01). Intact FGF23 did not correlate with iron. C-terminal FGF23 correlated inversely with iron (white women r=-0.134, p<0.0001; black women r=-0.188, p<0.01), having a steeper slope at iron <50mcg/dl than ≥50mcg/dl. Longitudinal changes in iron predicted changes in C-terminal FGF23. Spine BMD correlated with iron negatively (r=-0.076, p<0.01) in white women; femur neck BMD correlated with iron negatively (r=-0.119, p<0.0001) in black women. Both relationships were eliminated in weight-adjusted models. BMD did not correlate with FGF23. Serum iron did not relate to intact FGF23, but was inversely related to C-terminal FGF23. Intact FGF23 correlated with serum phosphorus. In weight-adjusted models, BMD was not related to intact FGF23, C-terminal FGF23 or iron. The influence of iron on FGF23 gene expression is not important in

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

    The objective of this study was to test whether supplementing dry cow rations with phosphorus (P) and magnesium (Mg) would interfere with the beneficial effect of zeolite supplementation on the periparturient blood calcium (Ca) concentration in dairy cattle. Three groups (A-C) of 10 Danish Jersey cows were each given the following daily supplements from 2 weeks before the expected date of calving until actual calving: group A: zeolite, monoammonium phosphate, standard dry cow mineral and vitamin mix, containing 61g magnesium phosphate; group B: zeolite, standard mineral and vitamin mix without the magnesium phosphate and group C: standard mineral and vitamin mix, monoammonium phosphate. All cows in group B had an apparently less variable serum calcium concentration around calving with no cases of milk fever and no subclinical hypocalcaemia or hypomagnesaemia recorded. In contrast, a parturient drop in blood Ca was seen in group A as well as group C. In group A, one cow was hypocalcaemic at calving, and developed milk fever. In group C, 12 blood samples, representing six cows, were hypocalcaemic, and three of these cows were treated for milk fever. All groups remained normomagnesaemic and there were no significant differences in blood Mg across groups. In conclusion, the combined P and Mg supplementation in addition to zeolite supplementation did not increase the serum Mg level (forage Mg 16.9g/day; 0.21% of DM). Combined P and Mg supplementation reduced the zeolite-induced hypophosphataemia but also reduced the stabilising effect of zeolite on parturient serum Ca. PMID:17600739

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

    Abstract Objective. Alteration of serum bilirubin level in acute episodes of psychosis in patients with schizophrenia has been reported but the pattern of this alteration is controversial. Methods. Patients diagnosed as schizophrenia (162, group S) or bipolar disorder (155, group B) entered the study. The control group consisted of 95 patients admitted to cardiac care unit who had no personal or family history of major psychiatric disorders. Pre- and post-admission levels of bilirubin were measured and compared within and between the groups. Patients were examined to exclude all other causes of hyperbilirubinemia. Group S and B participants were also evaluated using positive and negative syndrome subscale (PANSS) both at admission and discharge. Results. The mean admission bilirubin levels of all the groups were in the normal range (significantly higher in group S than groups B and C) and were affected by the score of general psychopathology subscale rather than the scores of positive symptoms subscale. Conclusions. Although bilirubin decreased in all three groups at discharge, the rate of decrease was significantly higher in group S. The reason for this is not clear and needs further study.

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

    Context: Low levels of serum 25 Hydroxyvitamin D [25(OH)D] have been linked to greater fracture risk in older women. Objective: This study aimed to determine whether higher 25(OH)D is associated with slower loss of bone mineral density (BMD) and lower fracture risk during the menopausal transition. Design, Setting, and Participants: This was a prospective cohort study at five clinical centers in the United States. Mean age was 48.5 ± 2.7 years. The fracture analysis included 124 women with an incident traumatic fracture, 88 with incident nontraumatic fracture, and 1532 women without incident fractures; average followup was 9.5 years. BMD analysis included 922 women with a documented final menstrual period. Main Outcome Measures: Serum 25(OH)D was measured by liquid chromatography tandem mass spectrometry at the third annual clinic visit. BMD was measured and incident fractures ascertained at each annual visit. Results: The mean 25(OH)D was 21.8 ng/mL; seven-hundred two (43%) of the women had 25(OH)D values <20 ng/mL. There was no significant association between 25(OH)D and traumatic fractures. In multivariate adjusted hazards models, the hazard ratio (HR) for nontraumatic fractures (95% confidence interval [CI]) was 0.72 (0.54–0.96) for each 10-ng/mL increase in 25(OH)D. Comparing women whose 25(OH)D was ≥20 vs <20 ng/mL, the HR (95% CI) for fracture was 0.54 (0.32–0.89). Changes in lumbar spine and femoral neck bone mineral density across menopause were not significantly associated with serum 25(OH)D level. Conclusion: Serum 25(OH)D levels are inversely associated with nontraumatic fracture in mid-life women. Vitamin D supplementation is warranted in midlife women with 25(OH)D levels <20 ng/mL.

    The objective of this study was to determine the effect of different dietary levels of sodium in diets with and without sodium chloride on mineral metabolism, including blood electrolyte levels and tibia mineralization parameters, in young turkeys (to six weeks of age). The influence of diets with a low (L), medium (M) and high (H) sodium content, at 0.34, 1.34 and 2.82 g/kg respectively, was compared. The content of chloride and potassium in turkey diets (1.7 - 5.9 and 11 g/kg, respectively) was above the recommended levels. The sodium-deficient diet L decreased the serum concentrations of sodium, chloride and phosphorus, and it increased the serum levels of calcium and magnesium in turkeys, compared with groups M and H. Relative to group L, different dietary sodium levels in groups M and H contributed to a similar increase in the body weights of birds (1.06 vs. 1.46 and 1.44 kg, p < 0.001) and in the absolute (4.60 vs. 6.83 and 6.62 g, p < 0.001) and relative tibia weight (0.42 vs. 0.46 and 0.46% body weight, p = 0.031). No significant differences were found between groups with respect to the content of ash, calcium and phosphorus in tibia dry matter. Supplemental sodium increased the bone density index (from 50.6 to 68.4 and 66.3 mg/mm in groups L, M and H, respectively, p < 0.001), the maximum bending moment (from 5.27 to 7.40 and 7.33 N/mm, p = 0.002) and the minimum breaking strength of tibia (from 0.136 to 0.191 and 0.189, p = 0.002). In conclusion, our study indicates that the applied dietary treatment with a moderate sodium level (1.34 g/kg) resulted in a rate of bird growth and tibia mineralization similar to those observed with the treatment with much higher Na content (2.82 g/kg).

    A combination of low serum calcium (Ca), high serum phosphorus (P), and low serum magnesium (Mg) has been observed in individual captive ruminants, primarily affecting kudu (Tragelaphus strepsiceros), eland (Taurotragus oryx), nyala (Tragelaphus angasii), bongo (Tragelaphus eurycerus), and giraffe (Giraffa camelopardalis). These mineral abnormalities have been associated with chronic laminitis, acute tetany, seizures, and death. Underlying rumen disease secondary to feeding highly fermentable carbohydrates was suspected to be contributing to the mineral deficiencies, and diet changes that decreased the amount of starch fed were implemented in 2003. Serum chemistry values from before and after the diet change were compared. The most notable improvement after the diet change was a decrease in mean serum P. Statistically significant decreases in mean serum P were observed for the kudu (102.1-66.4 ppm), eland (73.3-58.4 ppm), and bongo (92.1-64.2 ppm; P < 0.05). Although not statistically significant, mean serum P levels also decreased for nyala (99.3-86.8 ppm) and giraffe (82.6-68.7 ppm). Significant increases in mean serum Mg were also observed for kudu (15.9-17.9 ppm) and eland (17.1-19.7 ppm). A trend toward increased serum Mg was also observed in nyala, bongo, and giraffe after the diet change. No significant changes in mean serum Ca were observed in any of the five species evaluated, and Ca was within normal ranges for domestic ruminants. The mean Ca:P ratio increased to greater than one in every species after the diet change, with kudu, eland, and bongo showing a statistically significant change. The results of this study indicate that the diet change had a generally positive effect on serum P and Mg levels. PMID:20945636

    Cotinine is a major metabolite of nicotine. This study was planned to investigate the relationship between bronchoalveolar lavage (BAL) fluid cotinine levels and serum cotinine levels in smokers and nonsmokers with various pulmonary diseases and to investigate whether these levels are affected by passive smoking. Serum and BAL fluid cotinine levels were measured in 27 patients. BAL cotinine levels were measured using a sensitive ELISA kit produced to measure cotinine in saliva. Plates were read by microuant (BioTek, USA) micro plate reader. All patient serum cotinine levels were detectable except for one nonsmoker patient. However, BAL fluid cotinine levels were measurable in only 6 patients (two of them were nonsmokers). A significant positive correlation was seen between serum and BAL fluid cotinine levels (r = 0.726; p = 0.000). Serum cotinine levels were significantly higher in present smokers than non-smokers (21.0 +/- 16.01; 5.35 +/- 7.65; p = 0.004). However, there were no significant differences in BAL fluid cotinine levels between smokers and nonsmokers. Passive smoking can increase nicotine metabolites in serum and other body fluids, including BAL fluid. Since BAL fluid and serum cotinine levels were well correlated, there is no need to use invasive procedures, such as bronchoscopy and expensive, time consuming BAL fluid analyses. Serum cotinine levels can give a rough idea of smoking status. BAL fluid cotinine meaurements should be done for only scientific reasons. PMID:21073047

    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. PMID:27103976

    Certain minerals and trace elements are essential for the development of healthy nervous system. Altered serum levels of these elements may lead to the development of various diseases including epilepsy. The present study was designed to evaluate the association of serum calcium, magnesium, zinc and copper in the development of genetic generalized epilepsy [GGE; erstwhile known as idiopathic generalized epilepsy (IGE)] as well as idiopathic intractable epilepsy (IIE), in which seizures persist despite treatment with at least two or three antiepileptic drugs tolerated at reasonable dosage. 200 GGE patients and equal number of healthy controls were recruited for study with their written informed consent. The patients were further divided into responders and non-responders based on their response to antiepileptic drugs. Copper and zinc levels were assayed by atomic absorption spectrophotometer whereas calcium and magnesium were analyzed by Human Star 600 fully automated biochemistry analyzer. The patients with GGE had significant low levels of calcium, magnesium and zinc (1.85 ± 0.33, 0.69 ± 0.13 mmol/L and 11.33 ± 3.32 µmol/L respectively) and the corresponding values for controls were 2.27 ± 0.22, 0.89 ± 0.15, 12.71 ± 3.24 (p < 0.05). Significant high levels of copper were found in patients as compared to controls (26.69 ± 8.79 µmol/L; 16.64 ± 3.64) (p < 0.05). Significantly decreased levels of zinc were noted in non-responders (10.38 ± 2.99) compared to responders (12.62 ± 3.30) (p < 0.05). No significant difference was observed in serum calcium, magnesium and copper levels between responders and non-responders. In conclusion, low levels of calcium, magnesium, zinc and high levels of copper were found to be associated with GGE. Further, the patients with IIE were also found to have low levels of zinc.

    In this study we aimed to test central administration of CDP-choline on serum ghrelin, leptin, glucose and corticosterone levels in rats. Intracerebroventricular (i.c.v.) 0.5, 1.0 and 2.0 µmol CDP-choline and saline were administered to male Wistar-Albino rats. For the measurement of serum leptin and ghrelin levels, blood samples were obtained baseline and at 5, 15, 30, 60 and 120 min following i.c.v. CDP-choline injection. Equimolar doses of i.c.v. choline (1.0 µmol) and cytidine (1.0 µmol) were administered and measurements were repeated throughout the second round of the experiment. Atropine (10 µg) and mecamylamine (50 µg) were injected intracerebroventricularly prior to CDP-choline and measurements repeated in the third round of the experiment. After 1 µmol CDP-choline injection, serum ghrelin levels were suppressed significantly at 60 min (P=0.025), whereas serum leptin levels were increased at 60 and 120 min (P=0.012 and P=0.017 respectively). CDP-choline injections also induced a dose- and time-dependent increase in serum glucose and corticosterone levels. The effect of choline on serum leptin and ghrelin levels was similar with CDP-choline while no effect was seen with cytidine. Suppression of serum ghrelin levels was eliminated through mecamylamine pretreatment while a rise in leptin was prevented by both atropine and mecamylamine pretreatments. In conclusion; centrally injected CDP-choline suppressed serum ghrelin levels while increasing serum leptin levels. The observed effects following receptor antagonist treatment suggest that nicotinic receptors play a role in suppression of serum ghrelin levels,whereas nicotinic and muscarinic receptors both play a part in the increase of serum leptin levels.

    Background. Screening for biochemical markers is important for diagnosing colon cancer. In this study, the reliability of serum mesothelin levels as a potential diagnostic and screening instrument was evaluated concerning colon cancer. Methods. Ninety-five patients who had undergone colonoscopic examination and who were diagnosed with colon cancer were included in the study. The serum mesothelin levels were measured with the ELISA kits and were evaluated in terms of significant difference when compared between colon cancer and control group. Results. Patients with colon cancer had significantly higher mesothelin serum levels (P < 0.001) than the control groups. We found significant associations between serum levels and tumor grade, perineural invasion, and vascular invasion (resp., P < 0.001). Conclusion. Evaluating the serum levels of mesothelin has a potential to detect and screen the colon cancer in affected patients. Our data suggest that mesothelin exhibits effects towards colon cancer and serves as a biomarker for this deadly disease. PMID:25477701

    Magnesium, potassium, and sodium, cations commonly measured in serum, are involved in many physiological processes including energy metabolism, nerve and muscle function, signal transduction, and fluid and blood pressure regulation. To evaluate the contribution of common genetic variation to normal physiologic variation in serum concentrations of these cations, we conducted genome-wide association studies of serum magnesium, potassium, and sodium concentrations using ∼2.5 million genotyped and imputed common single nucleotide polymorphisms (SNPs) in 15,366 participants of European descent from the international CHARGE Consortium. Study-specific results were combined using fixed-effects inverse-variance weighted meta-analysis. SNPs demonstrating genome-wide significant (p<5×10−8) or suggestive associations (p<4×10−7) were evaluated for replication in an additional 8,463 subjects of European descent. The association of common variants at six genomic regions (in or near MUC1, ATP2B1, DCDC5, TRPM6, SHROOM3, and MDS1) with serum magnesium levels was genome-wide significant when meta-analyzed with the replication dataset. All initially significant SNPs from the CHARGE Consortium showed nominal association with clinically defined hypomagnesemia, two showed association with kidney function, two with bone mineral density, and one of these also associated with fasting glucose levels. Common variants in CNNM2, a magnesium transporter studied only in model systems to date, as well as in CNNM3 and CNNM4, were also associated with magnesium concentrations in this study. We observed no associations with serum sodium or potassium levels exceeding p<4×10−7. Follow-up studies of newly implicated genomic loci may provide additional insights into the regulation and homeostasis of human serum magnesium levels. PMID:20700443

    The relationship between sex steroids and osteoprotegerin (OPG) in patients with prostate cancer is not well established. Our aim was to evaluate serum OPG levels in patients with prostate cancer and its relationship with sex steroids, bone mineral density, bone turnover markers, and fractures. We performed a cross-sectional study including 91 patients with prostate cancer. We determined: bone mineral density by dual-energy x-ray absorptiometry, bone turnover markers, serum levels of sex steroids and osteoprotegerin, and prevalent radiographic vertebral fractures. Serum OPG levels were higher in patients with vertebral fractures (8.02 ± 2.0 vs 4.91 ± 0.28 pmol/L; P < .05). OPG level and the duration of hormonal therapy were related (r = 0.299, P = .004), but this association did not persist after adjustment for age. In patients without androgen deprivation therapy, serum OPG levels were correlated with the levels of total testosterone (r = 0.508, P = .001) and bioavailable testosterone (r = 0.311, P = .037). In patients receiving androgen deprivation therapy, serum OPG levels were correlated with levels of total estradiol (r = 0.199, P = .18), bioavailable estradiol (r = 0.37, P = .009), and free estradiol (r = 0.349, P = .016). In conclusion, in patients with prostate cancer treated with androgen deprivation therapy, serum OPG levels were correlated with the levels of total estradiol, bioavailable estradiol, and free estradiol. Our hypothesis is that in patients with androgen deprivation therapy, the higher relative estrogen levels could stimulate OPG production in response to the higher resorption state. Future prospective studies are needed to clarify the role of OPG in androgen deprivation therapy-mediated bone loss. PMID:21903971

    Abstract Recently, hepcidin, an antimicrobial-like peptide hormone, has evolved as the master regulator of iron homeostasis. Despite the growing evidence of iron imbalance in childhood-onset ischemic stroke, serum hepcidin level in those patients has not yet been researched. In this study, we aimed to estimate serum (hepcidin) level in acute ischemic stroke (AIS) patients and to investigate whether subcutaneous enoxaparin sodium, which is a low-molecular-weight heparin (LMWH) derivative, could modulate serum hepcidin level in those patients. This was a case–control study included 60 (AIS) cases, and 100 healthy children with comparable age and gender as control group. For all subjects’ serum hepcidin, interleukin-6 (IL-6), and soluble transferrin receptor [sTfR]) levels were assessed by (enzyme-linked immunosorbent assay [ELISA] method). Iron parameters including (serum iron, ferritin, transferrin, and total iron binding capacity [TIBC]) were also measured. The patients were subdivided according to treatment with an LMWH derivative into 2 groups and serum hepcidin levels were assessed initially and 1 week after stroke onset for all cases. We found that AIS cases had higher serum iron, ferritin, and IL6 levels compared to the control group (all P < 0.01). Serum hepcidin was significantly higher in AIS cases (median, 36[15–73]ng/mL) compared to the control group (median, 24[10–41]ng/mL; P < 0.01). On the 1st day of AIS diagnosis, serum hepcidin levels were similar in both stroke subgroups (P > 0.05). However, on the 7th day of diagnosis serum hepcidin level decreased significantly in AIS cases treated with LMWH (group 1) (median, 36 vs 21 ng/mL; P < 0.01, respectively). Meanwhile, no significant change was observed in serum hepcidin level in AIS cases not treated with LMWH (group 2) (P > 0.05). Serum hepcidin showed significant positive correlations with serum iron, transferrin saturation, ferritin, and IL6 (r = 0.375, P < 0

    Trace element levels are associated with the incidence of osteoporotic fractures, but related mechanisms remain unknown. Trace elements may interfere with growth, development and maintenance of bones. Therefore, we investigated whether plasma trace element levels are associated with bone mineral density in elderly males in Beijing. After epidemiologically investigating 91 elderly males with age ranging from 50 years to 80 years, we obtained a total of 30 healthy (group 1), 31 osteopoenic (group 2) and 30 osteoporotic (group 3) subjects. Blood was collected, and serum concentrations of trace elements were detected. Elderly males in the three groups were carefully matched in terms of body mass index. Iron, manganese, zinc, copper, selenium, cadmium and lead were analysed by inductively coupled plasma-mass spectrometry. Bone mineral density (BMD) was measured by QDR-2000 dual-energy X-ray absorptiometry. Correlation between BMD and serum element contents was analysed using SPSS16.0. The plasma levels of manganese, zinc, copper, selenium and lead were similar in all of the groups (P>0.05). Cadmium was significantly and negatively correlated with BMD of the lumbar vertebrae (P<0.05). Moreover, cadmium and iron contents significantly differed in osteoporotic and healthy groups. These elements may directly and correlatively affect BMD in elderly males. Many trace elements may directly and correlatively influence BMD. Future studies should be conducted to evaluate serum and bone levels of these trace elements to determine the relationship of these trace elements with osteoporosis. PMID:26770561

    This study measured the serum folic acid (FA) level in patients with erectile dysfunction (ED) and evaluated the possible association between the serum FA level and erectile function. The study divided 120 patients with ED into 3 groups of 40 patients each: those with severe, moderate and mild ED. Forty healthy men served as controls. Fasting serum samples were obtained, and the total testosterone, cholesterol and FA levels were measured using chemiluminescent immunoassays. There were no significant differences in the mean age, mean body mass index or mean serum total testosterone and cholesterol levels among the three ED groups and controls (P > 0.05). The mean serum FA concentrations were 7.2 ± 3.7, 7.1 ± 3.2, 10.2 ± 4.6 and 10.7 ± 4.6 ng ml(-1) in the severe, moderate and mild ED and control groups respectively. The mean serum FA concentration was significantly higher in the control group than in the severe and moderate ED groups (both P < 0.001), but not the mild ED group (P = 0.95). Considering the significant differences in the serum FA levels between the control and ED groups, serum FA deficiency might reflect the severity of ED. PMID:26302884

    Serum estradiol and serum estrone levels were assessed in 29 men in 14 men in whom myocardial infarction was ruled out; in 12 men without apparent coronary heart disease but hospitalized in an intensive care unit; and in 28 men who were not hospitalized and who acted as control subjects. (The 12 men who were hospitalized but who did not have coronary heart disease were included to control for physical and emotional stress of a severe medical illness.) Ages ranged from 21 to 56 years. Age, height, and weight did not differ significantly among groups. Blood samples were obtained in the patient groups on each of the first three days of hospitalization. The serum estrone level was significantly elevated in all four patient groups when compared with that in the control group. Estrone level, then, did not differentiate patients with and without coronary heart disease. Serum estradiol levels were significantly elevated in the groups with myocardial infarction, unstable angina, and in the group in whom myocardial infarction was ruled out. However, estradiol levels were not significantly elevated in the group in the intensive care unit without coronary heart disease when compared to the level in the normal control group. Serum estradiol levels, then, were elevated in men with confirmed or suspected coronary heart disease but were not elevated in men without coronary heart disease even under the stressful conditions found in an intensive care unit. Serum estradiol levels were significantly and positively correlated (p less than 0.03) with serum total creatine phosphokinase levels in the patients with myocardial infarction. The five patients with myocardial infarction who died within 10 days of admission had markedly elevated serum estradiol levels. The potential significance of these serum estradiol elevations is discussed in terms of estradiol's ability to enhance adrenergic neural activity and the resultant increase in myocardial oxygen demand.

    Purpose To compare different regimens of vitamin D with respect to its serum increment levels and bone mineral accrual in vitamin D-deficient children. Methods Children identified as being vitamin D deficient (serum levels<20 ng/mL) were divided into 3 treatment groups by stratified block randomization (group 1, 4,000 IU/day of vitamin D3 plus 50 mg/kg/day calcium for 12 weeks; group 2, 30,000 IU/wk of vitamin D3 plus 50 mg/kg/day calcium for 12 weeks; and group 3, 300,000 IU of vitamin D3 once intramuscularly plus 50 mg/kg/day calcium). After regimen completion, each child received a maintenance dose of 400 IU/day vitamin D3 plus 50 mg/kg/day calcium. Their serum vitamin D level was measured after 3 and 12 months. Total body less head bone mineral concentration (BMC) and total body less head bone mineral density (BMD) were measured after 12 months. Results The mean increment in serum vitamin D levels from baseline to 3 months was significantly higher in group 3 than in groups 1 and 2, but the levels from 3 to 12 months were almost similar among all 3 groups. There were no significant differences among the 3 groups with respect to percentage increase of BMD and BMC. Conclusion The injectable form of vitamin D was more efficacious than the oral forms in increasing the serum level to the normal range. All 3 regimens were equally effective in increasing the BMC and BMD. The 400 IU/day maintenance dose was sufficient to keep the serum level within the normal range. PMID:27588029

    Objective. The aim of study was to investigate the changes levels of serum ghrelin in HD patients and its relationship to some malnutrition markers compared with healthy controls. Methods. Forty-five patients on hemodialysis and forty healthy controls were studied. Biochemical parameters and serum ghrelin levels were measured. Both daily dietary intakes and body mass index (BMI) assessments were performed for evaluation of nutritional status. Results. Ghrelin concentrations were significantly reduced in patients undergoing hemodialysis when compared to healthy controls (5 ± 0.68 (1.1–18.5) pg/mL versus 7.8 ± 0.84 (2.4–18.3) pg/mL; P = 0.004). BMI and serum albumin in HD patients were markedly reduced compared to controls. The patients with an insufficient intake of energy and protein demonstrated slightly lower levels of serum ghrelin. A negative correlation between serum ghrelin concentration with age (r = −0.34, P = 0.02), BUN (r = −0.26, P < 0.01), and serum creatinine (r = −0.27, P < 0.01) was observed in HD patients. Conclusions. The findings suggest that decreased ghrelin levels in HD patients might be associated with anorexia. Further studies are needed to determine changes in serum ghrelin levels during dialysis and to clarify whether the decrease in ghrelin levels contributes to the malnutrition that is common in these patients.

    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. PMID:26568687

    Background: In this study Serum Vitamin C and Iron levels in Oral submucous fibrosis (OSMF) were estimated. The objective was to evaluate the correlation between Serum Vitamin C and Iron levels in OSMF individuals. Serum Iron content can be a predictor for the progression of this condition. OSMF is basically a disorder of collagen metabolism where Vitamin C gets utilized in conversion of proline into hydroxyproline, this hydroxylation reaction requires ferrous Iron and Vitamin C. Many studies regarding micronutrients and other antioxidants levels have been emphasized, but very few studies are done on the Serum levels of Vitamin C and its correlation with Iron in OSMF patients. Methods: Thirty five OSMF patients and 50 deleterious habit free healthy individuals (controls) were selected. Two ml of venous blood was collected from each individual. Vitamin C level in serum was estimated by 2-4 dinitrophenylhydrazine method and Iron estimated by Tripyridyl method. Results: The level of Serum Vitamin-C and Iron was significantly decreased in OSMF patients when compared to controls which were statistically significant. Conclusion: On the basis of these observations, it seems possible that the chemical, thermal and/or mechanical factors associated with the use of areca nut may act in conjunction with the Vitamin C and Iron deficiency leading to the development of OSMF. Therapeutic substitution of vitamin C and Iron may be recommended in the management of OSMF PMID:25565730

    Melatonin (MLT) shows an influence on gonadal steroid genesis, and has soporific effects. Serum MLT levels were examined during late pregnancy and 4 days after delivery in 25 women. Circulating levels of melatonin were analysed as integrated values (areas under the curve [AUC]) over 24 hours, 5 to 2 days before and 4 days after delivery. Antepartum AUCs were significantly increased compared with postpartum AUCs. Additionally, MLT levels were measured every 2 hours in a subgroup of 11 women during spontaneous labour between 08.00 and 12.00 h at a time when physiological serum MLT levels were low. Increased MLT levels were determined and compared to MLT levels measured in a previous evaluation of the antepartum AUCs. Elevated serum MLT levels during late-pregnancy and labour may influence the concentration of receptors of gonadal steroids in the gravid uterus at term and the psychic perception of painful uterine contractions during labour.

    Background The presence of PCB in caulking (sealant) material found in masonry buildings has been well-documented in several countries. A recent investigation of 24 buildings in the greater Boston area found that 8 buildings had high PCB levels in caulking materials used around window frames and in joints between masonry blocks. Workers removing caulking material have been shown to have elevated serum PCB levels. Methods This project compared serum PCB levels among male workers who installed and/or removed PCB-containing caulking material from buildings in the greater Boston area with reference serum PCB levels from 358 men from the same area. Serum PCB levels were measured in the same laboratory by liquid-liquid extraction, column chromatography clean-up and dual capillary column GC/microECD analysis. Results When the congener profiles were compared between the reference population and the construction workers, the serum levels of the more volatile, lighter PCBs (di-, tri-and tetrachloro, sum of IUPAC# 6–74) were substantially higher among the construction workers. One of the youngest workers had the lowest total serum PCB levels (sum of 57 congeners) of all 6 workers, but the contribution of more volatile (less chlorinated) PCB congeners (#16, 26,28,33,74,66, and 60) was markedly higher than in other 5 workers and reference men. Only this worker was working on a job that involved removing PCB caulking at the time of the blood sampling. Conclusion While the results of this pilot study are based upon small numbers (6 construction workers who handled PCB caulking), the serum PCB levels among the construction workers exceed the referents. Comparison of the congener profiles suggests that there are substantial differences between the construction workers and the general population samples. These differences, and the similarities of profiles among the construction workers strongly suggest that occupational contact with caulking material can be a major source of PCB

    Serum copper levels (SCL) and serum zinc levels (SZL) were evaluated in malignant melanoma patients at various clinical stages. Copper levels were generally found to be elevated, reflecting the degree and extent of tumor activity. Zinc levels and, hence, SCL:SZL ratios did not reflect tumor activity. SCL appeared to prognosticate disease progression in that all patients whose values never declined below 150 ..mu..g/100 ml died during the course of the study. However, not all patients who died from tumor metastases displayed persistent elevations of SCL. Patients receiving BCG immunotherapy appeared to have higher SCL than untreated patients.

    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 < 0.001). When treated with antithyroid regimens, the follistatin serum levels in HY group decreased to 1.54 [1.00, 1.88] ng/mL at the 6th month.

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

    Background: Patients, who survived from shotgun injuries, often have some retained lead pellets in their bodies. Several cases of lead toxicity have been reported regarding these patients. Objectives: This study seeks to compare the serum lead level in patients who have retained lead pellets in their bodies with the control group. Patients and Methods: In this case-control study, we gathered the serum lead levels of 25 patients with some retained lead pellets in their bodies due to shotgun and 25 volunteers without similar lead exposure and compared them in view of the age, gender, and living place. Results: While the mean serum lead level in both groups was lower than the standard level (i.e. 40 µg/dL) , the mean ± SD of serum lead level were 29 ± 12.8 µg/dL and 25.3 ± 6.4 µg/dL in the case and control groups, respectively without any significant difference (P = 0. 30) . However, a positive relationship was seen between serum lead level, and the number of retained lead pellets (r = 0.447, P = 0. 025) . Conclusions: Although extensive surgery to remove the lead pellets is not recommended in patients injured with shotguns, those with many retained lead pellets in their bodies should be considered at risk for lead poisoning and monitored carefully.

    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 (p<0.001) in vegetarian group compared to omnivores. We further grouped and analyzed our study subjects according to their gender and according to Hcy level (greater than or lower than 15µmol/L). A considerable number of vegetarian subjects 30% were having Hcy >15µmol/L compared to omnivores 6%, (p<0.001). Gender-wise comparison showed that 27.02% male and 38.46% females had >15µmol/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

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

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

    Recent meta-analyses of serum brain-derived neurotrophic factor (BDNF) have reported lower levels in patients with schizophrenia. However, most studies did not consider the potential confounding effects of time of collection, age, sex, smoking, and obesity. Here, we sought to examine differences in serum BDNF between medicated patients with schizophrenia compared with control subjects, taking into consideration the potential confounders of serum BDNF. Serum was obtained from a sample of fasted blood collected from all participants, and BDNF was assayed on a commercially available kit. After adjusting for potential confounders, there was no statistically significant difference between cases and control subjects (p = 0.261). In the model, body mass index emerged as the most significant predictor of serum BDNF (β = 0.22, p = 0.009). The present study did not support a role for serum BDNF as a biomarker in schizophrenia. This could be due to the nonspecific nature of serum BDNF and its association with both mental and physical conditions. PMID:27479612

    Adropin, a secreted protein, is encoded by the energy homeostasis associated (ENHO) gene. It has been implicated in the several physiological and pathological processes such as angiogenesis and apoptosis. Therefore, the aim of present study was to investigate serum adropin levels and ENHO gene expressions in systemic sclerosis (SSc) characterized by vasculopathy, inflammation, and progressive fibrosis of the skin and internal organs. The study includes 27 patients with SSc, 39 patients with Behçet's disease (BD), and 20 healthy controls (HC). Serum adropin levels and ENHO gene expressions by peripheral blood mononuclear cells were analyzed by ELISA method and by real-time PCR, respectively. The serum adropin levels were higher in the SSc and BD groups than in the HC group (p = 0.023 and p < 0.001, respectively). However, there were no significant differences among the groups in terms of ENHO gene expressions (p ANOVA = 0.149). There was no significant difference between the limited and diffuse cutaneous subtypes of SSc in terms of serum adropin level and ENHO gene expression. Moreover, serum adropin level and ENHO gene expression were not associated with the disease activity and severity indexes. ENHO gene expression was correlated with the triglyceride levels in the BD group (r = -0.426, p = 0.027). The augmented serum adropin levels may be expected in the chronic inflammatory disease and seem not to be characteristic of only SSc. However, further studies are needed to explain the precise role of adropin in SSc. PMID:27079850

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

    The aim of this study was to evaluate the relationship between maternal serum magnesium levels and preterm birth. This Nested case-control study carried out on 20 with preterm birth and 20 women at term birth at Imam Khomeini Hospital in Sari/Iran in 2008. The women with singleton gestation and intact fetal membrane suspected to preterm labor (case group), 10 cc blood samples were drawn into syringes and sent to laboratory of the hospital immediately. Sampling for control group was same as the case group. These samples recognized as control group just as birth occurring after week 37. Finally, serum magnesium level measured. Data analyzed using chi2, t-test and OR (Odd's Ratio). There was a relationship between the number of prenatal visits (p = 0.008) and stressful events associated with preterm birth (p < 0.02). Serum magnesium level was associated with preterm birth OR = 4.75, CI 95% = (0.48-46.91), Sensitivity, specificity, positive and negative predictive value of serum magnesium for preterm birth was 95, 50, 66.5 and 83.33%, respectively. Although, there was a correlation between serum magnesium levels and preterm birth, due to methodology of the study, a cohort study with the same cut off point and supplementation of magnesium in RTC studies is recommended.

    Claudins are the most important structural and functional components of tight-junction integral membrane proteins. They play roles in major cellular functions including growth and adhesion and are responsible for regulating the paracellular transport of molecules. The objective of this study was to determine the clinical significance of the serum levels of claudin-1, an oldest and important member of the claudin family, in melanoma patients. A total of 98 patients with a pathologically confirmed melanoma were enrolled into this study. Serum claudin-1 concentrations were determined by the solid-phase sandwich enzyme-linked immunosorbent assay method. Age-matched and sex-matched 43 healthy controls were included in the analysis. The median age at diagnosis was 51 years, ranging from 16 to 85 years. The majority of the patients were male (61%) and had axial localized (54%) and metastatic disease (61%). Moreover, most of the patients with metastatic disease had M1c (73%). The baseline serum claudin-1 levels of the melanoma patients were significantly lower than those of control subjects (median values 9.17 vs. 13.82 ng/ml, respectively, P<0.001). However, known clinical variables including age of the patient, sex, site of lesion, histology, lymph node involvement, stage of disease, serum lactate dehydrogenase levels, and response to chemotherapy were not found to be correlated with serum claudin-1 concentrations (P>0.05). Similarly, serum claudin-1 concentration was found to have no prognostic role in survival (P=0.524). In conclusion, serum levels of claudin-1 may have a diagnostic value in melanoma patients. However, its predictive and prognostic value has not been determined. PMID:26886788

    The aim of study was to evaluate the association between serum DHEAS levels and depression with a case-control study together with a meta-analysis. Radioimmunoassay (RIA) was performed to measure the serum DHEAS levels of all participants before and after treatment. Depression Patients were divided into mild depression and severe depression based on Hamilton depression scale (HAMD24) and received 5-hydroxytryptamine (5-HT) and citalopram (20mg/d) for 8 weeks. Case-control studies related to our study theme were enrolled for meta-analysis and Comprehensive Meta-analysis 2.0 (CMA 2.0) was used for statistical analysis. After treatment, DHEAS levels in depression patients were significantly increased, while before and after treatment, DHEAS levels were all lower in depression patients than in controls (all P<0.001); further analysis on age revealed that DHEAS levels were decreased with the rising of age. Meta-analysis results suggested that serum DHEAS levels (ng/mL) were significantly higher in healthy controls compared to depression patients (SMD=0.777, 95%CI=0.156-1.399, P=0.014). In conclusion, our study suggests that serum DHEAS levels are associated with the development of depression and it decreased with the rising of age. PMID:26205628

    The objective of the present study was to determine levels and calculate ratios of copartition coefficients among organochlorine pesticides β-HCH, pp'DDE, op'DDT and pp'DDT in maternal adipose tissue, maternal blood serum and umbilical blood serum of mother-infant pairs from Veracruz, Mexico. Organochlorine pesticides were analyzed in 70 binomials: maternal adipose tissue, maternal serum and umbilical cord serum samples, using gas chromatography with electron capture detection (GC-ECD). The results were expressed as mg/kg on fat basis. p,p'-DDE was the major organochlorine component, detected in every maternal adipose tissue (0.770 mg/kg), maternal serum sample (5.8 mg/kg on fat basis) and umbilical cord blood sample (6.9 mg/kg on fat basis). p,p'-DDT was detected at 0.101 mg/kg, 2.2 mg/kg and 5.9 mg/kg respectively, according to the order given above. β-HCH was detected at 0.027 mg/kg, 4.2 mg/kg and 28.0 mg/kg respectively. op'DDT was detected only in maternal adipose tissue at 0.011 mg/kg. The copartition coefficients among samples identify significant increases in concentrations from adipose tissue to maternal blood serum and to umbilical blood serum. The increase indicated that maternal adipose tissue released organochlorine pesticides to blood serum and that they are carried over to umbilical cord blood. PMID:21290101

    Background: Diabetes mellitus is a noncommunicable disease with a rising prevalence worldwide and in developing countries. The most commonly used diagnostic biofluid for detection of glucose levels is blood, but sample collection is an invasive and painful procedure. Thus, there arises a need for a noninvasive and painless technique to detect glucose levels. Aims and Objectives: The objectives of the present study were to estimate the glucose levels of saliva, to assess if any significant correlation existed between the serum and salivary glucose levels, and to correlate salivary glucose levels with regard to duration of diabetes, age, and gender. In the present study, serum and salivary glucose levels of 200 subjects (100 diabetic subjects and 100 nondiabetic subjects) were estimated by glucose oxidase method. Glycosylated hemoglobin levels were also measured in randomly selected 40 diabetic subjects. Results: The findings of present study revealed a significant correlation between salivary and serum glucose levels in both diabetic and nondiabetic subjects. No significant relationship was observed between salivary glucose levels and gender or age in both diabetics and nondiabetics and between salivary glucose levels and duration of diabetes in diabetics. Conclusion: On the basis of the findings, it was concluded that salivary glucose levels could serve as a potentially noninvasive adjunct to monitor glycemic control in diabetic patients.

    Refeeding syndrome is a life-threatening condition occurring in severely malnourished patients after initiating feeding. Severe hypophosphatemia with reduced adenosine triphosphate production has been implicated, but little data are available regarding electrolyte abnormalities. In this case, we report electrocardiographic changes consistent with hyperkalemia during potassium replacement after a serum level increase from 1.9 to 2.9 mEq/L. This was reversed by lowering serum potassium back to 2.0 mEq/L. In conclusion, the patient with prolonged malnutrition became adapted to low potassium levels and developed potassium toxicity with replacement. PMID:25456880

    Background Life style and physical activity play a pivotal role in prevention and treatment of osteoporosis. The mechanism for better bone metabolism and improvement of physical disorders is not clear yet. Trace minerals such as Ca, Mn, Cu, and Zn are essential precursors for most vital biological process, especially those of bone health. Objective The main target of this study was evaluating the effective role of supervised aerobic exercise for 1 hour/day, 3 days/week for 12 weeks in the functions of trace elements in bone health through measuring bone mineral density (BMD), osteoporosis (T-score), bone markers, and trace element concentrations in healthy subjects aged 30–60 years with age average of 41.2±4.9. Methods A total of 100 healthy subjects (47 males, 53 females; age range 30–60 years) were recruited for this study. Based on dual-energy x-ray absorptiometry (DEXA) scan analysis, the participants were classified into three groups: normal (n=30), osteopenic (n=40), and osteoporotic (n=30). Following, 12 weeks of moderate aerobic exercise, bone-specific alkaline phosphatase (BAP), BMD, T-score, and trace elements such as Ca, Mn, Cu, and Zn were assessed at baseline and post-intervention. Results Significant improvement in serum BAP level, T-score, and BMD were observed in all participants following 12 weeks of moderate exercise. Participants with osteopenia and osteoporosis showed significant increase in serum Ca and Mn, along with decrease in serum Cu and Zn levels following 12 weeks of aerobic training. In control group, the improvements in serum trace elements and body mass index were significantly linked with the enhancement in the levels of BAP, BMD hip, and BMD spine. These results supported the preventive effects of moderate exercise in healthy subjects against osteoporosis. In both sexes, the changes in serum trace elements significantly correlated (P<0.05) with the improvement in BAP, BMD hip, BMD spine, and body mass index in all groups

    Background Meteorin (METRN) is a recently described neutrophic factor with angiogenic properties. This is a nested case-control study in a longitudinal cohort study that describes the serum profile of METRN during different periods of gestation in healthy and preeclamptic pregnant women. Moreover, we explore the possible application of METRN as a biomarker. Methods and Findings Serum METRN was measured by ELISA in a longitudinal prospective cohort study in 37 healthy pregnant women, 16 mild preeclamptic women, and 20 healthy non-pregnant women during the menstrual cycle with the aim of assessing serum METRN levels and its correlations with other metabolic parameters. Immunostaining for METRN protein was performed in placenta. A multivariate logistic regression model was proposed and a classifier model was formulated for predicting preeclampsia in early and middle pregnancy. The performance in classification was evaluated using measures such as sensitivity, specificity, and the receiver operating characteristic (ROC) curve. In healthy pregnant women, serum METRN levels were significantly elevated in early pregnancy compared to middle and late pregnancy. METRN levels are significantly lower only in early pregnancy in preeclamptic women when compared to healthy pregnant women. Decision trees that did not include METRN levels in the first trimester had a reduced sensitivity of 56% in the detection of preeclamptic women, compared to a sensitivity of 69% when METRN was included. Conclusions The joint measurements of circulating METRN levels in the first trimester and systolic blood pressure and weight in the second trimester significantly increase the probabilities of predicting preeclampsia.

    The objective of this study is to examine and evaluate whether serum 25(OH)D is associated with disease activity in patients with rheumatoid arthritis (RA). Our results suggested that serum 25(OH)D in RA groups has significant lower level (35.99 ± 12.59 nmol/L) than that in the normal groups (54.35 ± 8.20 nmol/L, P < 0.05). Based on the DAS28, patients with RA were divided into four subgroups, and no differences were found in the four groups (P > 0.05). The 25(OH)D levels in complete remission, low disease activity, middle disease activity, and high disease activity group were 32.86 ± 12.26, 33.97 ± 13.28, 38.41 ± 10.64, and 38.94 ± 13.35 nmol/L, respectively. Based on the serum 25(OH)D levels, patients with RA were divided into inadequate group and normal group, and there were no significant differences in baseline characteristics and disease activity in the two groups. Our results showed that serum 25(OH)D levels in the inadequate group are significantly lower than those in the normal group. However, no correlations were found between 25(OH)D levels and disease activity among 116 patients with RA. The present findings will help to understand the association between 25(OH)D and disease activity of RA. PMID:26064964

    The study was done to find out the causes that changes the fasting serum glucose level in postmenopausal women. This was descriptive type of cross sectional study carried out over a period of one year from July 2014 to June 2015 in the department of physiology, Mymensingh Medical College, Mymensingh. Women of reproductive age (25-45 years) and clinically diagnosed 100 menopausal women (45-70 years) were included for this study. Convenience type of sampling technique was used for selecting the study subjects. Measurement of fasting serum glucose was done by GOD-PAP method. Data were expressed as mean±SD and statistical significance of difference among the groups were calculated by unpaired student's 't' test. The mean±SD of serum glucose in menopausal women were significant at 1% level of probability than women of reproductive age. This study revealed that postmenopausal women showed higher levels of fasting serum glucose level. Fasting blood sugar level between the study & control group were 7.69±2.37 and 4.59±0.73 and the difference was statistically significant. PMID:27612883

    Electromagnetic pulse (EMP) was a potentially harmful factor to the human body, and a biological dosimetry to evaluate effects of EMP is necessary. Little is known about effects of EMP on concentration of macro and trace elements in serum so far. In this study, Sprague-Dawley rats were randomly divided into 50-kV/m EMP-exposed group (n = 10), 100-kV/m EMP-exposed group (n = 10), 200-kV/m EMP-exposed group (n = 40), and the sham-exposed group (n = 20). The macro and trace element concentrations in serum were examined at 6, 12, 24, and 48 h after EMP exposure at different electric field intensities. Compared with the sham-exposed groups, the concentration of sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), iron (Fe), selenium (Se), and manganese (Mn) in rat serum was not changed significantly within 48 h after 200 pulses of EMP exposure at electric field intensity of 50, 100, and 200 kV/m although the K level was decreased and the Ca level was increased with the electric field intensity of EMP increasing. In addition, there was a tendency that the Zn level was decreased with the time going on within 48 h after EMP exposure. Under our experimental conditions, EMP exposure cannot affect the concentration of macro and trace elements in rat serum. There was no time-effect or dose-effect relationship between EMP exposure and serum element levels. The macro and trace elements in serum are not suitable endpoints of biological dosimetry of EMP.

    Mercury is an immunotoxic substance that has been shown to induce autoimmune disease in rodent models, characterized by lymphoproliferation, overproduction of immunoglobulin (IgG and IgE), and high circulating levels of autoantibodies directed at antigens located in the nucleus (anti-nuclear autoantibodies, or ANA) or the nucleolus (anti-nucleolar autoantibodies, or ANoA). We have reported elevated levels of ANA and ANoA in human populations exposed to mercury in artisanal gold mining, though other confounding variables that may also modulate ANA/ANoA levels were not well-controlled. The goal of this study is to specifically test whether occupational and environmental conditions (other than mercury exposure) that are associated with artisanal gold mining affect the prevalence of markers of autoimmune dysfunction. We measured ANA, ANoA, and cytokine concentrations in serum and compared results from mercury-exposed artisanal gold miners to those from diamond and emerald miners working under similar conditions and with similar socioeconomic status and risks of infectious disease. Mercury-exposed gold miners had higher prevalence of detectable ANA and ANoA and higher titers of ANA and ANoA as compared to diamond and emerald miners with no occupational mercury exposure. Also, mercury-exposed gold-miners with detectable ANA or ANoA in serum had significantly higher concentrations of pro-inflammatory cytokines IL-1β, TNF-α, and IFN-γ in serum as compared to the diamond and emerald miners. This study provides further evidence that mercury exposure may lead to autoimmune dysfunction and systemic inflammation in affected populations. PMID:20176347

    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 ..mu..U/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 ..mu..U/m1 (lognormal distribution). Although the mean +-1 SEM value of 0.63 +- 0.003 ..mu..Um1 for hyperthyroid patients and 0.76 +- 0.08 ..mu..U/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.

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

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

    Ten patients with uncomplicated malaria, ten with cerebral malaria and 37 controls (blood donors from blood bank) were included in the study. The serum cortisol levels of the patients were determined daily for 7 days while they were at the hospital. A radio-immunoassay method was used for quantitative measurement of cortisol in human serum. The mean serum cortisol level of patients with uncomplicated malaria was 528.2 +/- 123.9 nmol/l, with cerebral malaria was 516.0 +/- 80.5 nmol/l, and in controls was 393.8 +/- 141.0 nmol/l. There was a significant rise of serum cortisol levels in patients with malaria when compared to controls at the day of admission to hospital. There was no significant difference between uncomplicated malaria patients and those with cerebral malaria. There was also no significant difference between the different days of treatment up till day 7. We found no cortisol insufficiency in cases with falciparum malaria during acute and convalescent stages of illness. PMID:9740267

    AIM: To explore the role of ghrelin in gallstone disease. METHODS: We carried out a cross-sectional study in 150 subjects, 38 with gallstones (cases) and 112 controls. We also did a real-time PCR-RT study in twenty gallbladder samples each. Body mass index (BMI), serum insulin, ghrelin, and serum lipids were measured. Logistic regression analyses (univariate and multivariate) were conducted to estimate the probability of gallstone disease associated with serum ghrelin concentrations. RESULTS: Cases were statistically different from controls in gender distribution (P = 0.01), age (53 vs 44 yr, P = 0.002), BMI (28 vs 25; P = 0.004), and glucose (5.26 vs 4.98 mmol/L; P = 0.05). The prevalence of ghrelin serum levels above the third tercile was lower in subjects without metabolic syndrome (P < 0.05). In a multivariate model, we found a protective effect, when ghrelin values were higher than the median value (OR = 0.27, 95%CI 0.09-0.82, P = 0.02). Twenty (20%) gallbladder specimens expressed ghrelin mRNA. CONCLUSION: Serum ghrelin concentrations are associated with a protective effect of GD. PMID:16718795

    The role of trace elements in dengue virulence is not yet known. The present study assessed the serum levels of two micronutrients, copper and iron, in cases of dengue fever. The study involved 96 patients of whom 48 had either severe or non-severe forms of dengue (with and without warning signs), and the remaining 48 were patients with other febrile illnesses (OFI), used as controls. Serum levels of copper and iron were evaluated at admission and by the time of defervescence using commercially available kits. At admission, no difference in the level of serum copper was observed between cases and controls. In the group of dengue cases, the copper level was found to be significantly decreased in severe and non-severe cases with warning signs, compared to non-severe cases without warning signs. In contrast, by the time of defervescence the copper level was found to be increased in all dengue cases compared to OFI controls, but no difference was observed among dengue cases. Unlike OFI controls, dengue cases showed an increasing pattern of copper levels from admission until defervescence. On the other hand, no such significant differences were observed in the serum level of iron in the clinical groups, except for a decreased iron level found in severe cases, compared to non-severe dengue without warning signs. The results show that copper is associated with dengue severity and this finding emphasizes the need to investigate the involvement of trace elements in disease severity so as to improve the prognosis of dengue.

    There are conflicting reports on the correlation between serum selenium (Se) levels with rheumatoid arthritis (RA). Through a meta-analysis approach, the aim of the present study is to clarify the relationship between serum Se levels with RA. We searched literatures that met our predefined criteria in PubMed, ScienceDirect, and OVID published as of September 2015. Ten eligible articles with 14 case-control studies involving 716 subjects were identified. Overall, pooled analysis indicated that subjects with RA had lower serum levels of Se than the healthy controls (standardized mean difference (SMD) = -1.347, 95 % confidence interval (CI) = [-1.872, -0.823], p < 0.001). Further subgroup analysis indicated that subjects with RA had lower serum Se levels than healthy controls in Europe (SMD = -1.063, 95 % CI = [-1.571, -0.556], p < 0.001) and Asia (SMD = -3.254, 95 % CI = [-4.687, -1.821], p < 0.001) but not in USA (SMD = -0.322, 95 % CI = [-0.657, 0.012], p = 0.059). The serum Se levels were lower in RA than healthy controls measured by graphite furnace atom absorption spectrometry (GFAAS) (SMD = -1.026, 95 % CI = [-1.522, -0.530], p < 0.001), electrothermal absorption spectrometry (EAS) (SMD = -1.197, 95 % CI = [-2.373, -0.020], p < 0.05), flame atomic absorption spectrophotometry (FAAS) (SMD = -0.681, 95 % CI = [-1.049, -0.313], p < 0.001), and inductively coupled plasma-mass spectrophotometer (ICP-MS) (SMD = -11.707, 95 % CI = [-15.189, -8.224], p < 0.001) but not by neutron activation analysis (NAA) (SMD = -0.674, 95 % CI = [-1.350, 0.003], p = 0.051). In conclusion, this meta-analysis supports a significant association between low serum Se concentration with RA. However, this finding needs further confirmation by a trans-regional multicenter study to obtain better understanding of causal relationship between serum Se with RA of different human

    Accurate exposure assessment is an important step in both risk assessment and epidemiologic studies involving potential human exposure to environmental toxicants. Various methods have been used to assess human exposure. These methods include models based on one`s temporal and spatial nearness to the source, environmental levels of toxicant, and biological measures. The authors believe that the latter measure is the ``gold standard.`` In this article they present the serum 2,3,7,8-tetrachlorodibenzo-p-dioxin levels in residents of the contaminated zones in Seveso, Italy, in 1976, and delineate these data by age and gender. Some of these serum levels are among the highest ever reported and thus this population serves as a benchmark for comparison of human exposure and potential adverse health effects. One such potential population is that population consuming potentially contaminated fish.

    Recent studies have shown that ED is an early symptom of atherosclerosis. Fetuin-A, a glycoprotein secreted by the liver, kidneys and choroid plexus, has been linked to systemic fibrosis and calcification in human and rat studies. Deficiency of this compound may play a role in atherosclerosis and cardiovascular disease progression. The aim of the study was to examine whether serum fetuin-A level is related to erectile function or severity of ED. Sixty ED patients without cardiovascular disease were assigned to one of the three groups (mild, moderate or severe ED) depending on ED severity. Twenty healthy volunteers were included as the control group. The International Index of Erectile Function-5 questionnaire was used to measure erection quality in all four groups. Mean age, body mass index, total testosterone, low- and high-density lipoprotein cholesterol, and triglyceride levels did not significantly differ between the three erectile dysfunction and control groups (P > 0.05). The group with severe ED had a significantly lower mean fetuin-A level than the mild ED and control groups. For both mild and moderate ED groups, the mean serum fetuin-A level was significantly lower in comparison with the control group (P < 0.001). Serum fetuin-A level may be used as a supplemental biochemical parameter in preliminary evaluation of ED. PMID:26685713

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

    Serum immunoglobulin (Ig) levels were measured in 788 coalworkers and 121 nonmining controls for comparison with the radiological category of pneumoconiosis after taking into account age and smoking habit. In addition a simple assessment of humoral immune competence was made by estimating the titre of serum antibody against the common gut commensal Escherichia coli. Smoking was found to depress serum IgA and IgM while levels of IgG and IgA increased slightly with age. Men with radiological signs of coalworkers pneumoconiosis (CWP) had significantly raised levels of IgA and IgG with increasing pneumoconiosis category. Even coalworkers with less than category 1 simple pneumoconiosis had raised levels of IgA, suggesting that increased production of this immunoglobulin occurs before radiologically identifiable pathological changes have occurred in the lung tissue. No association between reduced humoral immune competence and radiological category of pneumoconiosis was found. Whether high Ig levels in men exposed to coal dust are merely a passive response to dusted lung tissue or whether they indicate that an immunological process is important in the development of pneumoconiotic lesions remains uncertain.

    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.

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

    2012-01-01

    Background 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. Methods 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. Results 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). Conclusions 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.

    Background Previous studies have implicated the important and active role of vitamin D in the immune system. Objectives The aim of this study was to evaluate serum levels of 25-hydroxyvitamin D in children with burn injuries. Materials and Methods In this cross-sectional study, 118 patients with various degrees of burn injuries were enrolled. A checklist consisting of demographic data, total body surface area (TBSA) affected by burn, degree of burn, serum level of 25(OH)D, total protein, albumin, electrolytes, and parathyroid hormone was recorded for each patient. Results Sixty-eight (57.6%) males and 50 (42.4%) females with a mean age of 4.04 years (SD = 3.04) were evaluated. The mean level of 25(OH)D was 14.58 ng/mL (SD = 6.94). Levels of 25(OH)D in four (3.39%) cases were higher than 30 ng/mL, while 95 (81.35%) cases had levels lower than 20 ng/mL, and 19 (16.10%) cases had levels of 21 - 30 ng/mL. The level of 25(OH)D was below recommended levels in 96.61% of cases, while 81.34% had vitamin D deficiency and 16.1% had insufficiency. We found a significant correlation between vitamin 25(OH)D and total protein, albumin, and total and ionized calcium (P < 0.001). There was also a significant negative correlation between 25(OH)D and TBSA affected by burn (P = 0.001). Conclusions The levels of 25(OH)D in children suffering from severe burns were low. Supplementation might be useful in patients with very low levels of serum vitamin D. PMID:27218060

    Alterations of trace element concentrations adversely affect biological processes and could promote carcinogenesis. Only a few studies have investigated the degree of changes in copper and zinc levels in colorectal cancer (CRC). The aim of the present study was to compare the serum copper (Cu) and zinc (Zn) concentrations in patients with CRC from Iran with those of healthy subjects. Cu and Zn concentrations in the serum of 119 cancer patients and 128 healthy individuals were measured by atomic absorption spectrometry. We found a significant decrease in the total mean serum Cu and Zn concentrations in CRC patients as compared with the control group (137.5 ± 122.38 vs. 160.68 ± 45.12 μg/dl and 81.04 ± 52.05 vs. 141.64 ± 51.75, respectively). However, the serum Cu/Zn ratio in the patient group was significantly higher than that measured in the control group (p = 0.00). There was no significant difference in the mean values of serum Cu and Zn concentrations between young (<60 years) and elderly (≥60 years) patients. However, the Cu/Zn ratio in <60-year cases was significantly higher than that in ≥60-year age group (p < 0.05). In addition, mean serum Cu level in normal weight patients was significantly higher than that in overweight/obese cases (132.31 ± 87.43 vs. 103.81 ± 53.72 μg/dl, respectively) (p < 0.05). There was no difference in mean serum Cu and Zn concentrations in patients stratified by the site, stage, or differentiation grade of tumors. Our findings suggest that imbalance in Cu and Zn trace element level is associated with CRC and might play an important role in cancer development among Iranian patients. PMID:26329996

    In the follow-up of children receiving renal allografts the early differential diagnosis of infections and rejection episodes is the main problem. Serum levels of neopterin (N), a pteridine released from stimulated macrophages, was determined by radioimmunoassay. Also interferon-gamma (IF) serum levels, a marker of T lymphocyte activity, were determined with an immunoradiometric assay in 19 kidney-transplanted children. Both, infections and rejection episodes, are accompanied by distinct increases in N. The IF are elevated 1-3 days earlier than N, the median values during infections being significantly (p less than or equal to 0.001) higher than those during rejection crises. The routine measurement of N and IF allow the simple, quick and reliable monitoring of the immune status, which seems to be of a high relevance for the daily monitoring of transplant recipients.

    CYFRA 21-1 is a fragment of cytokeratin 19 (CK 19). Four patients with large intrahepatic (or peripheral) cholangiocarcinoma (CC) and high serum levels of CYFRA 21-1 (normal, < or = 2 ng/ml) are reported. CYFRA 21-1 levels exceeded 9 ng/ml in all 4 patients. Carcinoembryonic antigen (CEA), was high in 1 (CEA; normal range, < or = 5.0 ng/ml) and carbohydrate antigen 19-9 (CA 19-9) was high in 3 (CA19-9; normal range, < or = 36 U/ml). We also measured serum levels of CYFRA 21-1 in 13 patients with hepatocellular carcinoma (HCC) more than 5 cm in diameter. Levels of CYFRA 21-1 exceeded 2 ng/ml in 9 of the HCC patients and were higher than 9 ng/ml in 2 of the HCC patients. Levels of alpha fetoprotein (AFP) and/or protein induced by vitamin K absence or antagonist II (PIVKA II) were elevated in all HCC patients (AFP, PIVKA II, respectively; normal range, < or = 10.0 ng/ml and < or = 0.1 AU/ml) CYFRA 21-1 levels were measured twice or three times during the clinical course in 2 CC patients and in 6 HCC patients, and increased gradually with tumor growth in the 2 CC patients and in 3 of the 6 HCC patients. Marked increases in serum CYFRA 21-1 levels in patients with large liver cancers, particularly in those with normal levels of AFP and PIVKA II, would suggest the existence of intrahepatic CC rather than HCC.

    Osteosarcoma is a rare malignant bone tumor most commonly occurring in children and young adults presenting with painful swelling. Various etiological factors for osteosarcoma are ionizing radiation, family history of bone disorders and cancer, chemicals (fluoride, beryllium, and vinyl chloride), and viruses. Status of fluoride levels in serum of osteosarcoma is still not clear. Recent reports have indicated that there is a link between fluoride exposure and osteosarcoma. Glycoproteins and glycosaminoglycans are an integral part of bone and prolonged exposure to fluoride for long duration has been shown to cause degradation of collagen and ground substance in bones. The present study was planned to analyze serum fluoride, sialic acid, calcium, phosphorus, and alkaline phosphatase levels in 25 patients of osteosarcoma and age- and sex-matched subjects with bone-forming tumours other than osteosarcoma and musculo-skeletal pain (controls, 25 each). Fluoride levels were analyzed by ISE and sialic acid was analyzed by Warren's method. Mean serum fluoride concentration was found to be significantly higher in patients with osteosarcoma as compared to the other two groups. The mean value of flouride in patients with other bone-forming tumors was approximately 50% of the group of osteosarcoma; however, it was significantly higher when compared with patients of group I. Serum sialic acid concentration was found to be significantly raised in patients with osteosarcoma as well as in the group with other bone-forming tumors as compared to the group of controls. There was, however, no significant difference in the group of patients of osteosarcoma when compared with group of patients with other bone-forming tumors. These results showing higher level of fluoride with osteosarcoma compared to others suggesting a role of fluoride in the disease. PMID:19390788

    Background Endocan is a recently introduced marker of endothelial dysfunction. The objective of this study was to compare serum endocan levels in patients with restless legs syndrome (RLS) and control subjects in order to elucidate whether RLS is associated with endothelial dysfunction. Methods A total of 31 drug naïve female patients with RLS and 31 age- and BMI-matched women were included in the study. Patients with pathological or physiological conditions or with a history of medication use that could potentially influence endothelial functions were excluded, as well as those with alcohol or drug abuse history. The two groups were compared with routine blood tests and serum endocan levels. Results Patients with RLS had lower serum endocan levels than the controls (P=0.037). There was a negative bivariate correlation between RLS severity score and serum endocan levels (r=−0.406, P=0.023). While white blood cell count was significantly higher in RLS group, 25-hydroxy vitamin D3, vitamin B12, transferrin saturation rate, and HDL-cholesterol were significantly lower. Creatininemia and diastolic blood pressure were also marginally insignificantly lower in RLS group. Due to the presence of differences between two groups in these variables, a linear regression analysis was performed that showed a positive association between endocan and creatininemia (β=0.310, P=0.022), and a negative association between endocan and RLS (β=−0.502, P<0.001). Conclusion The results of this study seem to suggest that patients with RLS may have better endothelial functions when compared with the general population and that these patients may be better protected against atherosclerosis.

    Aim: This study was conducted to investigate the effect of selenomethionine and omega-3 fatty acid on serum mineral profile and nutrient utilization of broiler chicken. Materials and Methods: The present study was a 2×3 factorial arrangement of two levels of selenomethionine (0 and 0.3 ppm) and three levels of omega-3 fatty acid (0, 0.5 and 1%). Day-old Vencobb broiler chicks (n=180), were randomly assigned in six treatment groups. The experiment lasted for 42 days. Treatment groups followed of: Group I was a control. Group II, III, IV, V and VI were supplemented with 0 ppm selenomethionine with 0.5% omega-3 fatty acid, 0 ppm selenomethionine with 1% omega-3 fatty acid, 0.3 ppm selenomethionine with 0% omega-3 fatty acid, 0.3 ppm selenomethionine with 0.5% omega-3 fatty acid and 0.3 ppm selenomethionine with 1% omega-3 fatty acid, respectively. Linseed oil was used as a source of omega-3 fatty acid while sel-plex is used for selenomethionine supplementation. Results: Significant (p<0.05) interaction exist between selenomethionine and omega-3 fatty acid for serum zinc and iron concentration whereas, it was non-significant for serum calcium and copper. Significantly (p<0.05) increased concentration of selenium, zinc, iron and phosphorus was observed in birds fed 0.3 ppm selenomethionine whereas, significantly (p<0.05) increased zinc and iron was observed in birds fed 0.5% omega-3 fatty acid. There was significant (p<0.05) interaction exist between selenomethionine and omega-3 fatty acid for calcium and phosphorus retention percentage. The maximum retention of calcium and phosphorus was recorded in birds supplemented with 0.3 ppm selenomethionine in combination with 0.5% omega-3 fatty acid. There was marked interaction between selenomethionine and omega-3 fatty acid for hemoglobin (Hb), total erythrocytic count, total leukocytic count and platelets (p<0.05) however, it was non-significant for mean corpuscular volume, mean corpuscular Hb, MCH concentration and

    ABSTRACT Introduction: Trace elements are primary components of biological structures; however, they can be toxic when their concentrations are higher than those needed for biological functions. Materials and Methods: In the present study serum levels of trace elements were measured in 30 patients (mean age was 26.9±11.2 years) newly diagnosed with germ cell testicular cancer and 32 healthy volunteers (mean age: 27.4±10.8) by using furnace atomic absorption spectrophotometer. Serum samples were stored at-20°C until assays. Results: In patients with germ cell testicular cancer, the diagnosis was seminoma in 15, mix germ cell tumor in 7, embryonal carcinoma in 4, yolk sac tumor in 2 and teratoma in 2 patients. There was stage I testicular tumor in 19 patients (63.3%) while stage II in 6 patients (20.0%), stage IIIA in 4 patients (13.3%) and stage IIIC in one patient (3.4%). It was found that serum Co, Cu, Mg and Pb levels were increased (p<0.05), whereas Fe, Mn, and Zn levels were decreased in patients with testicular cancer (p<0.05). Conclusions: These alterations may be important in the pathogenesis of testicular cancers; however, further prospective studies are needed to identify the relationship between testicular cancer and trace elements.

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

    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. PMID:25996886

    Background. Leprosy reactions are acute inflammatory episodes that occur mainly in the multibacillary forms of the disease. The reactions are classified as type 1 (reverse reaction) or type 2 (erythema nodosum leprosum). Leprosy-associated oxidative stress has been widely demonstrated. Several recent studies have shown uric acid (UA) to have antioxidative effects under pathologic conditions. The objective of this study was to assess serum levels of UA in patients with leprosy reactions, with the aim of monitoring their levels before and after treatment, compared with levels in leprosy patients without reactions. Methods. The study included patients aged 18–69 years assisted at a leprosy treatment reference center in the Central Region of Brazil. Patients who were pregnant; were using immunosuppressant drugs or immunobiologicals; or had an autoimmune disease, human immunodeficiency virus infection, acquired immune deficiency syndrome, or tuberculosis were excluded. Upon recruitment, all individuals were clinically assessed for skin lesions and neural or systemic impairment. Some patients had already completed treatment for leprosy, while others were still undergoing treatment or had initiated treatment after being admitted. The treatment of the reactional episode was started only after the initial evaluation. Laboratory assessments were performed upon admission (baseline) and at approximately 30 and 60 days (time points 1 and 2, respectively). Results. A total of 123 leprosy patients were recruited between June 2012 and June 2015; among them, 56, 42, and 25 presented with type 1, type 2, and no reactions, respectively. Serum UA levels were significantly reduced in patients with type 2 leprosy reactions compared with patients in the control group and remained lower in the two subsequent assessments, after initiation of anti-reaction treatments, with similar values to those recorded before the treatment.

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

    Studies have shown a relationship between vitamin D and psoriasis. We compared serum levels of vitamin D of 20 psoriasis patients and 20 controls. The median vitamin D level was 22.80 ± 4.60 ng/ml; the median in the cases was 23.55 ± 7.6 ng/ml, and in controls 22.35 ± 3.10 ng/ml (p = 0.73). Only 2 cases and 4 controls had sufficient levels of vitamin D, although without statistical significance between the groups (p = 0.608). Levels were lower in women with psoriasis compared with those in male patients (20.85 ± 6.70 x 25.35 ± 2.90 ng/ml, p = 0.03), a finding that was not observed among controls. PMID:26131882

    We evaluated the hypothesis that the noncaffeine gastric acid stimulant effect of coffee might be by way of serum gastrin release. After 10 healthy volunteers drank 50 ml of coffee solution corresponding to one cup of home-made regular coffee containing 10 g of sugar and 240 mg/100 ml of caffeine, serum total gastrin levels peaked at 10 min and returned to basal values within 30 min; the response was of little significance (1.24 times the median basal value). Drinking 100 ml of sugared water (as control) resulted in occasional random elevations of serum gastrin which were not statistically significant. Drinking 100 ml of regular or decaffeinated coffee resulted in a prompt and lasting elevation of total gastrin; mean integrated outputs after regular or decaffeinated coffee were, respectively, 2.3 and 1.7 times the values in the control test. Regular and decaffeinated coffees share a strong gastrin-releasing property. Neither distension, osmolarity, calcium, nor amino acid content of the coffee solution can account for this property, which should be ascribed to some other unidentified ingredient. This property is at least partially lost during the process of caffeine removal. PMID:3745848

    1991-01-01

    A simple and sensitive radioreceptor assay (RRA) has been developed to measure melatonin levels in serum. The assay is based on competition between 2-({sup 125}I)iodomelatonin (({sup 125}I)MEL) and melatonin for binding to high-affinity binding sites in chick forebrain. To measure the amount of melatonin present in a serum sample, it was extracted with dichloromethane and added to the assay medium. The percentage inhibition of radioligand binding in the presence of the extracted serum was determined and compared to the percent displacement by known amounts of melatonin in a standard curve. There was little or no cross-reactivity with other structurally related compounds. The sensitivity of the assay is {approximately}1.5pg/0.15 mL and the intra- and inter-assay variations are approximately 8%. Since the RRA results are comparable to that of an established radioimmunoassay (RIA), it provides a sensitive and rapid alternative to the more time consuming RIA.

    BACKGROUND: The potential benefits of earlier referral to a nephrologist of patients with elevated levels of serum creatinine include identifying and treating reversible causes of renal failure, slowing the rate of decline associated with progressive renal insufficiency, managing the coexisting conditions associated with chronic renal failure and facilitating efficient entry into dialysis programs for all patients who might benefit. METHODS: A subcommittee of the Canadian Society of Nephrology, which included representatives from family practice and internal medicine, conducted a MEDLINE search for the period 1966 to 1998 using the key words referral and consultation, dialysis, hemodialysis, peritoneal dialysis, renal replacement therapy and kidney diseases. Where published evidence was lacking, conclusions were reached by consensus. GUIDELINES: Earlier referral to nephrologists of patients with elevated creatinine levels is expected to lead to better health care outcomes and lower costs for both the patients and the health care system. All patients with newly discovered renal insufficiency (as evidenced by serum creatinine elevated to a level above the upper limit of the normal range of that laboratory, adjusted for age and height in children) must undergo investigations to determine the potential reversibility of disease, to evaluate the prognosis and to optimize planning of care. All patients with an established, progressive increase in serum creatinine level should be followed with a nephrologist. Adequate preparation for dialysis or transplantation (or both) requires at least 12 months of relatively frequent contact with a renal care team. Nephrologists should provide consultation in a timely manner for any patient with an elevated serum creatinine level. In addition, they should provide advice about what aspects of the condition require particularly urgent or emergency assessment. SPONSORS: This clinical practice guideline has been endorsed by the Canadian

    Systemic autoimmune diseases (SADs) are associated with lower bone mass and an increased risk of fractures. Sclerostin has a pivotal role in bone metabolism. Available data on circulating sclerostin levels in healthy subjects are limited, whereas those in SAD patients are absent. Our objective was to determine circulating sclerostin concentrations in systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and Crohn's disease (CD) patients, and to analyze the factors associated with sclerostin concentrations. In this cross-sectional case-control study, serum sclerostin levels were measured in 38 SLE patients, 20 CD patients, 8 SSc patients and 20 healthy controls using a sclerostin ELISA. The mean values of the sclerostin (95% confidence interval) were 35.36 pmol l(-1) (12-101) in patients and 33.92 pmol l(-1) (2.31-100) in control subjects. The mean sclerostin value was 36.4 pmol l(-1) (22.1-48.5) in SLE patients, 26.7 pmol l(-1) (17.3-36.3) in CD patients and 51.8 pmol l(-1) (26.5-77.1) in SSc patients (P=0.001). Serum sclerostin levels were positively correlated with age (P<0.001), body mass index (BMI) (P=0.01) and lumbar spine Z-score (P=0.001) and negatively with creatinine clearance (P=0.001). Glucocorticoid treatment did not affect sclerostin levels. Sclerostin levels seem to have a heterogeneous pattern in different autoimmune diseases. SLE and SSc patients did not differ from healthy controls regarding sclerostin levels. The CD group had significantly lower values compared with SSc patients. Factors associated with sclerostin levels in autoimmune diseases seem to be the same than in the general population. PMID:26909149

    Background: Inflammation is involved in development, progression, and complications of atherosclerotic disease. Clinical studies have indicated that the level of monocyte chemoattractant protein 1 (MCP-1), IL-18, and adhesion molecules correlates with the severity of atherosclerosis and can predict future cardiovascular events. Experimental studies have shown pentoxifylline (PTX) reduces these factors in animal models. The purpose of the present pilot study was to evaluate effect of PTX on a group of inflammatory biomarkers in patients with coronary artery disease (CAD). Methods: Forty patients with angiographically documented CAD, who fulfilled inclusion and exclusion criteria, were entered in the double-blind, randomized, pilot clinical study. The patients were randomly given PTX (400 mg three times daily) or placebo (3 tab/day) for 2 months. Serum concentrations of MCP-1, IL-18, intercellular adhesion Molecule 1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) were measured before and at the end of intervention by enzyme-linked immunosorbant assay. Results: Our study showed that the serum levels of ICAM-1 and VCAM-1 was decreased in the study population after two-month treatment (P<0.05). Conclusion: Based on the results of our pilot study, administration of PTX in CAD patients significantly decreases adhesion molecules levels. PMID:24375159

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

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

    Introduction Type-2 Diabetes Mellitus (T2DM) and metformin both can lower serum B12 (s.B12). Raised serum Homocysteine (s.Hcy) is considered as an early marker of B12 deficiency. Aim The study aimed to check whether homocysteine levels are more sensitive indicator of s. B12 deficiency or not among diabetics using metformin. Materials and Methods Mean s.B12 and s.Hcy levels of 30 cases (diabetics on metformin <5years) were compared with 30 diabetic controls not on metformin and 31 nondiabetic controls and statistically analysed by ANOVA and post-hoc tests. Results No significant differences in either s.B12 mean or s.Hcy mean were found between cases and diabetic controls. s.B12 mean did not differ significantly but s.Hcy mean was significantly higher among nondiabetics as compared to diabetic control. s. B12 level of Nondiabetic group was in borderline category while mean s. B12 levels of cases and diabetic control groups was in normal category but nearer to the lower cut off. Mean s.Hcy values in all the groups were high. Pearson correlation showed strong association between s.B12 and s.Hcy in all the groups. Additionally equation based on linear regression was derived to calculate either of the s.B12 or s.Hcy. On Receiver Operative Characteristic (ROC) curve, area under curve value was 0.842 for the value of s.Hcy. Conclusion In this study neither metformin nor T2DM could be identified as a cause for s.B12 lowering and raised s.Hcy in the scenario of low normal levels of s.B12 (<300pmol/L). If B12 deficiency recognized early using s. Hcy, consequences due to B12 deficiency can be prevented or delayed among nondiabetics as well as among diabetics and metformin users. PMID:27190787

    Objective To compare the level of vitamin D3 in cutaneous melanoma patients, with or without disease activity, with reference values and with patients from a general hospital. Methods The serum levels of vitamin D3 were measured in cutaneous melanoma patients, aged 20 to 88 years, both genders, from January 2010 to December 2013. The samples from the general group were processed at Hospital Israelita Albert Einstein (control group). Data analysis was performed using the Statistics software. Results A total of 100 patients were studied, 54 of them men, with mean age of 54.67 years, and 95 Caucasian. Out of these 100 patients, 17 had active disease. The average levels of vitamin D3 in the melanoma patients were lower than the level considered sufficient, but above the average of the control group. Both groups (with or without active disease) of patients showed a similar distribution of vitamin D3 deficiency. Conclusion Vitamin D3 levels in melanoma patients were higher than those of general patients and lower than the reference level. If the reference values are appropriate, a large part of the population had insufficient levels of vitamin D, including those with melanoma, or else, this standard needs to be reevaluated. No difference in vitamin D3 levels was found among melanoma patients with or without active disease. More comprehensive research is needed to assess the relation between vitamin D and melanoma.

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

    The pulsatile release of cortisol from the adrenal glands is controlled by a hierarchical system that involves corticotropin releasing hormone (CRH) from the hypothalamus, adrenocorticotropin hormone (ACTH) from the pituitary, and cortisol from the adrenal glands. Determining the number, timing, and amplitude of the cortisol secretory events and recovering the infusion and clearance rates from serial measurements of serum cortisol levels is a challenging problem. Despite many years of work on this problem, a complete satisfactory solution has been elusive. We formulate this question as a non-convex optimization problem, and solve it using a coordinate descent algorithm that has a principled combination of (i) compressed sensing for recovering the amplitude and timing of the secretory events, and (ii) generalized cross validation for choosing the regularization parameter. Using only the observed serum cortisol levels, we model cortisol secretion from the adrenal glands using a second-order linear differential equation with pulsatile inputs that represent cortisol pulses released in response to pulses of ACTH. Using our algorithm and the assumption that the number of pulses is between 15 to 22 pulses over 24 hours, we successfully deconvolve both simulated datasets and actual 24-hr serum cortisol datasets sampled every 10 minutes from 10 healthy women. Assuming a one-minute resolution for the secretory events, we obtain physiologically plausible timings and amplitudes of each cortisol secretory event with R2 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.

    Adipsin is a protease produced at high levels by adipose tissue. It is involved in complement activation and metabolic control. The objective of this study was to determine the changes in adipsin levels during different stages of normal pregnancy, and its association with obstetric outcomes, such as preeclampsia. This nested case-control study in a longitudinal cohort included normal pregnant (n = 54) and preeclamptic (n = 18) women, both followed throughout pregnancy. Additionally, some of the normal pregnant women were followed up three months postpartum (n = 18). Healthy non-pregnant women were also studied during their menstrual cycle (n = 20). The results of this study show that in healthy non-pregnant women, adipsin levels did not change significantly during the menstrual cycle. In normal pregnant women, adipsin levels were lower (p < 0.01) when compared with non-pregnant healthy women, but these serum levels increased again during postpartum (p < 0.001). Adipsin levels were significantly elevated in preeclamptic women in late pregnancy (P < 0.01). A significant correlation was not found between leptin and adipsin during the three periods of gestation studied in healthy pregnant and preeclamptic women. Our results suggest that adipsin may be involved in pregnancy-associated metabolic changes. Moreover, the increase of adipsin levels towards late gestation in preeclamptic women could be related to the pathophysiology of this disease. PMID:26832661

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

    Background: Diabetic retinopathy is one of the leading causes of blindness in the world. Hypomagnesemia has been reported to occur at an increased frequency among patients with type 2 diabetes compared with their counterparts without diabetes. Hypomagnesemia has been linked to poor glycemic control. Many studies have been undergone to find out the precipitated factors of retinopathy such as duration and type of diabetes, hyperglycemia, hypomagnesemia and increased urinary total protein levels. Aim: This study was carried out to study the correlation between serum magnesium levels, glycosylated hemoglobin and urinary total protein levels in diabetic patients with retinopathy. Materials and Methods: The study population comprised of 30 type 2 diabetic patients without retinopathy as Group 2, 30 type 2 diabetic patients with retinopathy as Group 3 in the age group 45-75 years as cases and 60 age and sex matched healthy individuals as controls (Group 1). Determination of Serum Magnesium (photometric xylidyl blue method), glycosylated hemoglobin, Hb1C (IFCC), fasting blood glucose, postprandial blood glucose (glucose oxidase method) and urine total protein (Pyrogallol red method) was carried out. The statistical software SPSS 11.0 and Systat 8.0 were used for the analysis of the data. Results: Hypomagnesemia was observed in cases compared with both Group 2 and Group 3. FBS, PPBS, HbA1c, Urine total protein levels were increased in cases (without retinopathy and with retinopathy) compared with controls. Conclusion: Hypomagnesemia and albuminuria individually or in conjunction serve as indicators for dysglycemia and could be used as marker for the risk of development of diabetic retinopathy.

    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. PMID:23862162

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

    Abstract High levels of serum uric acid (SUAC) are frequently detected in patients with psoriasis. However, the relationship between psoriasis and hyperuricemia remains unknown. Here we conducted a meta-analysis to identify the SUAC levels in subjects with psoriasis and to determine whether there is an associated risk between psoriasis and hyperuricemia. A comprehensive search of the literature from January 1980 to November 2014 across 7 databases (MEDLINE, Embase, Cochrane Central Register, and 4 Chinese databases) was conducted to determine whether there is an associated risk between psoriasis and hyperuricemia. Among the 170 identified reports, 14 observational studies were included in this meta-analysis. We found a significant higher SUAC level (MD 0.68, 95% CI 0.26–1.09; P = 0.002) in patients with psoriasis in Western Europe, but no significant differences were found between the East Asia and India subgroup (MD 1.22, 95% CI –0.13–2.56; P = 0.08) or the Middle East subgroup (MD 0.48, 95% CI –0.49–1.44; P = 0.33). Similar results were obtained from the meta-analysis of SUAC levels in subjects with severe psoriasis. Our meta-analysis showed that the correlation between psoriasis and hyperuricemia was either ethnicity- or region-dependent and that patients with psoriasis in Western Europe were more likely to have hyperuricemia.

    Background. Carbohydrate 19.9 antigen (CA19.9) has been used in the diagnosis and followup of gastrointestinal tumours. The aim of this prospective longitudinal study was the evaluation of CA19.9 levels in patients with chronic hepatitis and hepatic cirrhosis hepatitis C virus and B virus correlated. Materials and Methods. 180 patients were enrolled, 116 with HCV-related chronic liver disease (48% chronic hepatitis, 52% cirrhosis) and 64 with HBV-related chronic liver disease (86% chronic hepatitis, 14% cirrhosis). Patients with high levels of CA19.9 underwent abdominal ecography, gastroendoscopy, colonoscopy, and abdominal CT scan. Results. 51.7% of patients with HCV-related chronic liver disease and 48.4% of those with HBV-related chronic liver disease presented high levels of CA19.9. None was affected by pancreatic or intestinal neoplasia, cholestatic jaundice, or other diseases potentially able to induce Ca19.9 elevations. CA19.9 levels were elevated in 43.3% of HCV chronic hepatitis, in 56.3% of HCV cirrhosis, in 45.1% of HBV chronic hepatitis, and in 58% of HBV cirrhosis. Conclusions. CA19.9 commonly increases in the serum of patients with chronic viral hepatitis. Elevation of CA 19.9 is not specific for neoplastic disease and is related to the severity of fibrosis and to the viral aetiology of hepatitis. PMID:24282817

    Increasing evidence suggests the association between obesity and bone metabolism. However, whether excessive fat accumulation has a beneficial or adverse effect on bone health remains controversial. Chemerin is a novel adipocyte-derived hormone and a chemoattractant cytokine that regulates adipogenesis. This study was performed to investigate the associations of serum chemerin with bone mineral density (BMD) and serum pro-inflammatory cytokine levels in 543 Chinese obese postmenopausal women. BMD of the femoral neck and lumbar spine, lean mass, and fat mass were measured using dual energy X-ray absorptiometry. Anthropometric assessment and laboratory measurements were performed. The age, time after menopause, and fat mass were negatively correlated with femoral and lumbar BMD, whereas lean mass was positively correlated with aforementioned variables. Furthermore, BMD at the lumbar spine was inversely associated with serum chemerin and TNF-α levels (r = -0.155, P = 0.001; r = -0.147, P = 0.001). Multiple linear regression analyses showed that serum chemerin levels were negatively correlated with BMD at the lumbar site after controlling for the age, lean, and fat mass (β = -0.125, P = 0.001). Chronic low-grade inflammation state in obese population has an inverse effect on bone mass. Chemerin as an adipocytokine and chemoattractant negatively affects the bone mass of Chinese obese postmenopausal women. Further studies are needed to confirm the potential role of chemerin in the crosstalk between bone and fat accumulation in obese population. PMID:27583869

    A common problem in determining the health consequences of radiation exposure is factoring out other carcinogenic influences. The conditions in Namibia provide a test case for distinguishing the effects of long-term low-dose exposure to uranium from the other environmental factors because of good air quality and the lack of other industries with negative health effects. Present records indicate a much higher prevalence of cancer among male workers in the open-pit uranium mine in Namibia compared with the general population. The objective of the present study was to determine whether long-term exposure to low doses of uranium increases the risk of a biological radiation damage which would lead to malignant diseases and to derive a dose-response model for these miners. To investigate this risk, we measured uranium excretion in urine, neutrophil counts and the serum level of FSH, LH and testosterone and analyzed chromosome aberrations in whole blood cells using fluorescence in situ hybridization. A representative cohort of 75 non-smoking, HIV-negative miners was compared to a control group of 31 individuals with no occupational history in mining. A sixfold increase in uranium excretion among the miners compared to the controls was recorded (P < 0.001). Furthermore, we determined a significant reduction in testosterone levels (P < 0.008) and neutrophil count (P < 0.004) in miners compared to the unexposed controls. A threefold increase in chromosome aberrations in the miners compared to the nonexposed controls was recorded (P < 0.0001). Most remarkably, cells with multiple aberrations such as "rogue" cells were observed for the first time in miners; these cells had previously been found only after short-term high-dose radiation exposure, e.g. from the Hiroshima atomic bomb or the Chernobyl accident. We conclude that the miners exposed to uranium are at an increased risk to acquire various degrees of genetic damage, and that the damage may be associated with an

    Background: Bone mineral densiy (BMD) is known to be affected by serum 25-hydroxyvitamin D (25(OH) D) levels, intact parathyroid hormone (iPTH) levels. Indian data pertinent to above observation is scant. Our study aimed to investigate the relationships between serum 25-hydroxyvitamin D (25(OH) D) levels, intact parathyroid hormone (iPTH) levels and bone mineral density (BMD) in a cohort of Indian patients. Materials and Methods: Adults with or without fragility fractures with low BMD at the hip or lumbar spine were evaluated clinically along with laboratory investigations. T-scores of the hip and spine were derived from BMD-DEXA (dual-energy X-ray absorptiometry). Multivariate regression models were used to investigate the relationships between serum 25(OH) D, iPTH and BMD. Results: Total of 102 patients (male:female = 38:64) with a mean age of 62.5 ± 6.4 years were included in the study. Forty-four patients had osteopenia. Osteoporosis was present in 58 patients. The mean values for serum 25(OH) D and iPTH levels were 21.3 ± 0.5 ng/ml and 53.1 ± 22.3 pg/ml, respectively. In 84.3% of patients, serum 25(OH) D levels were below 30 ng/ml (Normal = 30-74 ng/ml), confirming vitamin D deficiency. There was no association between 25(OH) D levels and BMD at the hip or lumbar spine (P = 0.473 and 0.353, respectively). Both at the hip and lumbar spine; iPTH levels, male gender, body mass index (BMI) and age were found to be significant predictors of BMD. Patients with higher BMI had significantly lower BMD and T-score. At levels <30 ng/ml, 25(OH) D was negatively associated with iPTH (P = 0.041). Conclusion: Among our cohort of patients with low BMD, no direct relationship between serum 25(OH) D levels and BMD was observed. However, a negative correlation between iPTH and 25(OH) D at serum 25(OH) D concentrations <30 ng/ml. Serum iPTH levels showed a significant negative association with BMD at the hip and lumbar spine. Our findings underscore the critical role of

    Primary aldosteronism (PA) is one of the most frequent forms of secondary hypertension, associated with atherosclerosis and higher risk of cardiovascular events. Platelets play a key role in the atherosclerotic process. The aim of the study was to evaluate the platelet activation by measuring serum levels of soluble CD40L (sCD40L) and P-selectin (sP-selectin) in consecutive PA patients [subgroup: aldosterone-secreting adrenal adenoma (APA) and bilateral adrenal hyperplasia (IHA)], matched with essential hypertensive (EH) patients. The subgroup of APA patients was revaluated 6-months after unilateral adrenalectomy. In all PA group, we measured higher serum levels of both sP-selectin (14.29±9.33 pg/ml) and sCD40L (9.53±4.2 ng/ml) compared to EH patients (9.39±5.3 pg/ml and 3.54±0.94 ng/ml, respectively; p<0.001). After removal of APA, PA patients showed significant reduction of blood pressure (BP) values, plasma aldosterone (PAC) levels and ARR-ratio, associated with a significant reduction of sP-selectin (16.74±8.9 pg/ml vs. 8.1±3.8 pg/ml; p<0.01) and sCD40L (8.6±1 ng/ml vs. 5.24±0.94 ng/ml; p<0.001). In PA patients, we found a significant correlation between sP-selectin and sCD40L with PAC (r=0.52, p<0.01; r=0.50, p<0.01, respectively); this correlation was stronger in APA patients (r=0.54; p<0.01 r=0.63; p<0.01, respectively). Our results showed that PA is related to platelet activation, expressed as higher plasma values of sCD40L and sP-selectin values. Surgical treatment and consequent normalization of aldosterone secretion was associated with significant reduction of sCD40L and sP-selectin values in APA patients. PMID:27101095

    Objectives To assess the importance of lipids and lipoproteins on longitudinal cognitive performance and cognitive health in late life and to consider moderating factors such as age and sex which may clarify conflicting prior evidence. Design A 16-year prospective cohort study of health and cognitive aging. Participants 819 adults from the Swedish Adoption Twin Study of Aging (SATSA), 50 years and older at the first cognitive testing, including 21 twin pairs discordant for dementia. Measurements Up to five occasions of cognitive measurements encompassing verbal, spatial, memory and perceptual speed domains across a 16-year span. Baseline serum lipids and lipoproteins including HDL, apoA1, apoB, total serum cholesterol, and triglycerides. Results The effect of lipids on cognitive change was most evident prior to age 65. In women higher HDL and lower apoB and triglycerides predicted better maintenance of cognitive abilities over age, particularly verbal ability and perceptual speed. Lipid values were less predictive of cognitive trajectories in men and, where observed, were in the contrary direction: i.e., higher total cholesterol and apoB values predicted better perceptual speed performance though faster rates of decline. In twin pairs discordant for dementia, higher total cholesterol and apoB levels were observed in the twin who subsequently developed dementia. Conclusions Elevated lipids may constitute a more important risk factor for cognitive health before age 65 than after. Findings for women are consistent with clinical recommendations, while for men the findings correspond with earlier age-associated shifts in lipid profiles and the importance of lipid homeostasis to cognitive health.

    Primary Snoring (PS) has been positioned at the milder end of the Sleep-Disordered Breathing severity continuum characterized by snoring and it is usually underestimated. PS is defined as snoring without apnea, frequent arousals, or gas exchange abnormalities and recent studies demonstrated that children with PS have increased blood pressure and reduced arterial distensibility. The association between adipokines and SDB has been recently investigated, though most of the studies were focused on OSAS where intermittent hypoxia characterizing the disease may lead to an inflammatory cascade and to the release of several adipokines, contributing to oxidative stress. Resistin, initially described s an adipokine increasing insulin resistance, has been recently identified as a novel important member of the cytokine family involved in the regulation of inflammation. The aim of our study was to investigate circulating resistin levels in normal weight children with PS. Sixty-five children of normal weight aged between 4 and 14 years of age were selected for habitual snoring. Children with positive polysomnography were excluded from the study. Serum resistin levels were detected in all children with PS. Thirty-three healthy non-snorer children with similar age, sex and BMI were selected as a control group. A significantly higher level of resistin was observed in patients with PS compared to the control group (4.67±1.91 ng/ml vs 3.98±1.58 ng/ml; p<0.01). Patients with inconclusive pulse oximetry showed significantly higher resistin levels than those with negative recordings recordings (5.29±1.91 ng/ml vs 4.20±1.93 ng/ml; p<0.008). Moreover, there was a significant increasing trend between sieric adipokine level and the frequency of snoring (p<0.006). Our results suggest that systemic inflammation and oxidative stress may also play a significant role in the pathophysiology of PS. PMID:25280038

    The aim of this study was to evaluate the relationship between serum testosterone levels and arterial blood pressure (BP) in the elderly. We studied 356 non-diabetic, non-smoking, non-obese men aged 60 to 80 years and untreated for hypertension. All subjects were evaluated in the morning after an overnight fast. Evaluation included measurements of the following: BP (by mercury sphygmomanometer, Korotkoff I and V), body weight, height and free testosterone (T) plasma levels (by radioimmunoassay). According to the BP values, the subjects were classified as normotensives (NT; n=112; SBP/DBP<140/90 mmHg), systolic and diastolic hypertensives (HT; n=127; SBP/DBP>140/90 mmHg), and isolated systolic hypertensives (ISH; n=117; SBP>140 mmHg and DBP<90 mmHg). T values decreased with increasing age in all 3 groups and was significantly lower in HT (-15%) and ISH men (-21%) than in NT men (p<0.05). In each group, the T levels showed a highly significant negative correlation with BMI (p<0.001). A significant negative correlation was also found between T levels and SBP in NT (r=-0.35, p<0.001), ISH (r=-0.67, p<0.001), and HT (r=-0.19, p<0.05) men, whereas a negative correlation with DBP was observed only in the NT men (r=-0.19, p<0.05). Adjusting for the BMI confirmed a significant difference in plasma T levels between ISH and NT men, but not between HT and NT men. Multiple regression analysis employing BP as a dependent variable confirmed a strong relationship between T levels and SBP in all 3 groups, whereas a significant relationship between T levels and DBP was found only in NT men. In conclusion, although further studies are needed to clarify the relationship between plasma T levels and BP, our findings suggest that in elderly men with ISH, the reduced plasma levels of testosterone might contribute to the increased arterial stiffness typical of these subjects.

    Interleukin-15 (IL-15) has important anabolic effects on muscle protein metabolism through a decrease in the ATP-ubiquitin-dependent proteolytic pathway. The role of IL-15 in human cancer cachexia is unknown. The aim of this study was to assess the relationship between interleukin-15 (IL-15) in cancer patients with cachexia at diagnosis of malignancy and 8 weeks later. An observational study of 21 cancer patients (with and without cachexia) and 8 healthy subjects was conducted. Body composition was measured by leg-to-leg impedance. Serum IL-15 levels were assessed at baseline and after 4 and 8 weeks. Baseline IL-15 values were similar in cancer patients and in healthy subjects. Cancer patients with lower baseline levels of IL-15 (<2 pg/ml) had significantly higher fat mass (%) along the study. Eighteen patients completed the study: five patients showed an increase of 3.7 kg at the end of the study (5.4% of body weight) and showed a mean increase of IL-15 of 1.32 pg/ml (121%) at 4 weeks and 2.32 pg/ml (197%) at 8 weeks, as compared with mean decrease of -4.1 kg (-5.3%) and -0.09 pg/ml (-2.5%) and 0.6 pg/ml (40.8%) in the 13 patients who lost weight (P=0.001 and P=0.022, respectively). Changes of IL-15 at 4 and 8 weeks were directly associated with changes in body weight, body mass index (BMI), fat-free mass and muscle mass (P<0.05), and indirectly associated with percentage of weight loss (P<0.05). In summary, although the results indicate that IL-15 does not have a role in cancer cachexia pathogenesis, the association during evolution between serum IL-15 and changes in weight and muscle mass suggests a possible role of IL-15 as a marker of the body composition response in cancer patients who are losing weight at the time of diagnosis.

    Background: The main aim of this study is to evaluate the association between serum cholesterol level and abdominal obesity in adult men and women in the north of Iran. Materials and Methods: This cross-sectional and analytical study was conducted on the 1956 subjects (990 men and 966 women) between 25 and 65 years old chosen by cluster sampling. Plasma cholesterol was measured in the morning after a 12 h fast and determined by auto-analyzer. Hypercholesterolemia (HC) was defined by a total plasma cholesterol level over 200 mg/dl. Waist circumference ≥102 cm and ≥88 cm in men and women were defined as abdominal obesity. SPSS 16.0 software was used for statistical analysis and P < 0.05 considered as statistical significance. Results: Averagely, the mean of age was 44.2 years and mean ± standard deviation of plasma total cholesterol level was 203 ± 11.3 mg/dl. The HC was seen in 50.8% of subjects with a more common in women than in men. Compared with normal subjects, in abdominal obese people, the odds ratio (OR) of HC was (OR = 4.208 [95% confidence interval [CI]: 1.939–9.130]) and (OR = 3.956 [95% CI: 1.821–8.592]) in men aged 25–35 and 35–45 years, respectively. In women aged 25–35 years, it was (OR = 3.444 [95% CI: 1.959–6.056]) in abdominal obese compared with normal subjects. Conclusion: Hypercholesterolemia was revealed as a major health problem among adults, and it was associated with abdominal obesity especially in the early middle-age in the north of Iran. This association was not significant in men and women after the age of 45 and 35, respectively. PMID:26097812

    Previous studies have suggested that vitamin E (VE) may affect bone health, but the findings have been inconclusive. We examined the relationship between VE status (in both diet and serum) and bone mineral density (BMD) among Chinese adults. This community-based study included 3203 adults (2178 women and 1025 men) aged 40-75 years from Guangzhou, People's Republic of China. General and dietary intake information were collected using structured questionnaire interviews. The serum α-tocopherol (TF) level was quantified by reversed-phase HPLC. The BMD of the whole body, the lumbar spine and left hip sites (total, neck, trochanter, intertrochanter and Ward's triangle) were measured using dual-energy X-ray absorptiometry. In women, the dietary intake of VE was significantly and positively associated with BMD at the lumbar spine, total hip, intertrochanter and femur neck sites after adjusting for covariates (P(trend): 0·001-0·017). Women in quartile 3 of VE intake typically had the highest BMD; the covariate-adjusted mean BMD were 2·5, 3·06, 3·41 and 3·54% higher, respectively, in quartile 3 (v. 1) at the four above-mentioned sites. Similar positive associations were observed between cholesterol-adjusted serum α-TF levels and BMD at each of the studied bone sites (P(trend): 0·001-0·022). The covariate-adjusted mean BMD were 1·24-4·83% greater in quartile 4 (v. 1) in women. However, no significant associations were seen between the VE levels (dietary or serum) and the BMD at any site in men. In conclusion, greater consumption and higher serum levels of VE are associated with greater BMD in Chinese women but not in Chinese men. PMID:26507315

    The discovery of a hyperferritinemia is most of the time fortuitous. The diagnostic approach aims at looking for the responsible etiology and at verifying if an iron hepatic overload is present or not. Three diagnostic steps are proposed. The clinical elements and a few straightforward biological tests are sufficient at first to identify one of the four main causes: alcoholism, inflammatory syndrome, cytolysis, and metabolic syndrome. None of these causes is associated with a significant iron hepatic overload. If the transferring saturation coefficient is raised (>50%) a hereditary hemochromatosis should be discussed. Secondly, less common disorders will be discussed. Among these, only the chronic hematological disorders either acquired or congenital are at risk of iron hepatic overload. Thirdly, if a doubt persists in the etiologic research, and the serum ferritin level is very high or continues to rise, it is essential to verify that there is no iron hepatic overload. For that purpose, the MRI with study of the iron overload is the main test, which will guide the therapeutic attitude. Identification of more than a single etiology occurs in more than 40% of the cases. PMID:25640247

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

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

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

    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.

DKK-1 and SOST serum levels were assessed at baseline and were compared between the subgroup of patients fulfilling ASAS criteria for SpA (n = 486; 68.6%) and 80 healthy controls. Results Mean SOST serum levels were lower in ASAS+ patients than healthy controls (49.21 ± 25.9 vs. 87.8 ± 26 pmol/L; p<0.0001). In multivariate analysis, age (p = 5.4 10−9), CRP level (p<0.0001) and serum DKK-1 level (p = 0.001) were associated with SOST level. Mean DKK-1 serum levels were higher in axial SpA patients than controls (30.03 ± 15.5 vs. 11.6 ± 4.2 pmol/L; p<0.0001). In multivariate analysis, DKK-1 serum levels were associated with male gender (p = 0.03), CRP level (p = 0.006), SOST serum level (p = 0.002) and presence of sacroiliitis on radiography (p = 0.05). Genetic association testing of 10 SNPs encompassing the DKK-1 locus failed to demonstrate a significant contribution of genetics to control of DKK-1 serum levels. Conclusions DKK-1 serum levels were increased and SOST levels were decreased among a large cohort of patients with early axial SpA compared to healthy controls. DKK-1 serum levels were mostly associated with biological inflammation and SOST serum levels. PMID:26313358

    Background: The study assessed whether low maternal serum cholesterol during early pregnancy is associated with preterm delivery. Patients and Methods: It was a prospective observational cohort study involving pregnant women at gestational age of 14-20 weeks over a period of 12 months. Blood samples were obtained to measure total serum cholesterol concentrations and the sera were then analysed enzymatically by the cholesterol oxidase: p-aminophenazone (CHOD PAP) method. Results: The study showed an incidence of 5.0% for preterm delivery in the low risk study patients. Preterm birth was 4.83-times more common with low total maternal cholesterol than with midrange total cholesterol (11.8% versus 2.2%, P = 0.024). Conclusion: Low maternal serum cholesterol (hypocholesterolaemia) is associated with preterm delivery. Optimal maternal serum cholesterol during pregnancy may have merit, therefore pregnant women should be encouraged to follow a healthy, balanced diet. PMID:25298606

    The diagnosis and clinical significance of blunt cardiac injury remains controversial. Cardiac troponin I is not found in skeletal muscle and has a high sensitivity for myocardial ischemia or injury. We hypothesized that normal troponin levels 4 to 6 hours postinjury would effectively exclude the diagnosis of cardiac contusion. A prospective evaluation of all blunt trauma patients older than 16 and admitted with the possible diagnosis of blunt cardiac injury was undertaken. Patients in whom this diagnosis was considered had an electrocardiogram (EKG) on admission, serum troponin, CPK and isoenzymes 4 to 6 hours postinjury, and admission with overnight telemetry. Other laboratory data and radiographic imaging was obtained as indicated. Seventy-two patients met criteria for entry into the study. Data was incomplete or inaccurately obtained on six patients, and they were excluded. Forty patients had normal troponins and normal EKG's on admission and were discharged the following day without any untoward effect. Sixteen patients were admitted with abnormal EKGs. All of these 16 patients had normal troponins 4 to 6 hours after their injury. They all did well and were discharged the following day. Ten patients had elevated troponins 4 to 6 hours after injury. One died two days later from refractory cardiogenic shock. Another was noted to have severely depressed left ventricular function by echocardiography. The other eight patients sustained no cardiac sequelae and were discharged once recovered from injuries. In the hemodynamically stable patient a normal troponin 4 to 6 hours after injury excludes clinically significant blunt cardiac injury. This holds true whether the admission EKG is normal or not. An elevated troponin does not definitively diagnose a clinically significant contusion. However, these patients should be monitored at least for 24 hours. Patients suspicious for cardiac contusions who have normal troponins and no other serious injuries may be safely

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

    In late 1983, we conducted a cross-sectional epidemiologic study to evaluate persons at risk of exposure to three chemical waste sites by comparing clinical disease end points and clinical chemistry parameters with serum polychlorinated biphenyls (PCB) levels. A total of 106 individuals participated in the study. The only statistically significant finding in regard to self-reported, physician-diagnosed health problems was a dose-response relationship between serum PCB levels and the occurrence of high blood pressure; however, this association failed to achieve statistical significance (p = 0.08) when we controlled for possible confounding effects of both age and smoking. Serum triglyceride and cholesterol levels were also higher in the group with elevated serum PCBs; additionally, there were isolated statistically significant correlations of serum aspartate aminotransferase (SGOT) with serum lipid fraction-adjusted PCB level (r = -0.21) and serum albumin (r = -0.24) and total bilirubin (r = 0.30) with serum PCB level. Although the ranges of serum levels reported herein from exposures to PCBs in the general environment are lower than those that have been associated with acute symptoms or illness in other studies, whether these levels are associated with long-term health risks is not known. Associations of such chronic, low-dose exposures with observable health effects as suggested by this study must be evaluated further before any final conclusions can be drawn. PMID:3104024

    Objectives: To explore the correlation between serum cystatin C level and elderly hypertension with coronary heart disease patients. Methods: 500 hypertensive patients combined coronary heart disease were selected by coronary angiography. 321 of them were elderly patients with hypertension (male 204, female 117), and 400 of them were elderly patients with coronary heart disease (male 257, female 143), The serum cystatin C level of all patients were detected by immunoturbidimetry, and analyzed the correlation between the serum cystatin C level and different degree of blood pressure and the degree of coronary artery stenosis in elderly patients. Results: The serum cystatin C level was closely related with the blood pressure and the degree of the coronary artery stenosis. The higher the blood pressure level and the more serious the coronary artery stenosis, the higher the serum cystatin C level; The serum cystatin C level of hypertensive patients with coronary heart disease patients (Group D) were markedly higher than the level of the patients without hypertension and coronary heart disease patients (Group A), and the level of the patients with coronary heart disease (Group B) and the hypertension group (Group C) (P < 0.05). Conclusion: The serum cystatin C level of elderly patients with hypertension and coronary heart disease were closely related with the degree of blood pressure and coronary arteries stenosis. The serum cystatin C maybe a predictor of disease severity in elderly hypertensive patients with coronary heart disease. PMID:26131241

    Background Vitamin D is known to have diverse effects on various systems in the body. There is evidence to suggest that a link exists between the serum vitamin D status and tuberculosis. The present study was designed to assess the alterations in serum 25-hydroxyvitamin D levels in newly diagnosed sputum acid fast bacilli (AFB) positive pulmonary tuberculosis patients and to study the association, if any, between serum vitamin D levels and different levels of sputum smear positivity. Methods Serum 25-hydroxyvitamin D levels were estimated in 65 sputum AFB positive pulmonary tuberculosis patients and 65 age and gender-matched healthy controls. Results The levels of serum 25 hydroxy-vitamin D in tuberculosis patients were not statistically different from the levels of serum 25 hydroxy-vitamin D in healthy controls. However, among patients with pulmonary tuberculosis, there was a significant negative correlation between the levels of serum 25 hydroxy-vitamin D and levels of sputum positivity. Conclusion Serum vitamin D levels negatively correlates with bacterial load in patients with active pulmonary tuberculosis. PMID:27433175

    Clinical investigations have indicated women have higher levels of adipocyte fatty acid binding protein (A-FABP) than men. The present study aimed to identify factors related to gender difference in serum A-FABP levels. A total of 507 participants (194 men, 132 premenopausal women, and 181 postmenopausal women) were enrolled in the present study. Serum A-FABP levels increased in the order from men to premenopausal women to postmenopausal women in both body mass index categories (<25.0 and ≥25.0 kg/m2; all P < 0.05). Multiple stepwise regression analyses showed that after adjustment for factors related to serum A-FABP levels, the trunk fat mass was an independent and positive factor of serum A-FABP levels. For men, total testosterone was associated independently and inversely with serum A-FABP levels. For pre- and postmenopausal women, bioavailable testosterone and total testosterone were independent and positive factors associated with serum A-FABP levels, respectively. The present study demonstrated that the androgen was correlated with the serum A-FABP levels negatively in men, but positively in women. With these effects on the fat content, especially trunk fat, androgen might contribute to the gender difference in serum A-FABP levels. PMID:27270834

    The lower levels of serum uric acid (UA) correlated with meningitis have been reported. However, comparison of UA levels among different kinds of infections of central nervous system (CNS) and changes of UA levels before and after treatment are unknown. Our study aimed to investigate the antioxidant status of serum UA in five common types of CNS infections. We retrospectively evaluated serum UA levels of 399 patients with different types of CNS infections including viral meningitis or meningoencephalitis (VM), brain cysticercosis (BC), tuberculous meningitis or meningoencephalitis (TM), cryptococcus meningitis or meningoencephalitis (CM) and bacterial meningitis or meningoencephalitis (BM), and 119 healthy controls. The changes of serum UA were examined and analyzed. The serum levels of UA in patients with CNS infections were significantly lower than those in normal subjects and among in TM, CM and BM groups were apparently lower when compared with VM and BC groups; otherwise, after effective therapy, serum UA levels were obviously higher than before. Our findings showed that patients with CNS infections had lower serum UA levels, which was independent of the classification and the serum UA levels increased obviously after valid treatment, the variation of UA levels might be considered as an indicator of clinical curative effect in patients with CNS infections.

    High-altitude deacclimatization syndrome (HADAS) is emerging as a severe public health issue that threatens the quality of life of individuals who return to lower altitude from high altitude. In this study, we measured serum levels of SOD, MDA, IL-17A, IL-10, TNF-α, and HADAS score in HADAS subjects at baseline and 50th and 100th days and to evaluate the relationship between interleukins, including IL-17A, and HADAS. Our data showed that and the serum IL-17A levels and HADAS score decreased over time in the HADAS group, and serum IL-17A levels were significantly higher in the HADAS group at baseline and 50th day compared with controls (p < 0.05). Furthermore, baseline serum levels of MDA and TNF-α were significantly higher, while SOD and IL-10 levels were lower in HADAS subjects compared with controls (p < 0.05). It is interesting that serum levels of IL-17A were clearly interrelated with HADAS incidence and severity (p < 0.05). ROC curve analysis showed that combined serum IL-17A and IL-10 levels were a better predictor of HADAS incidence than serum levels of IL-17A or IL-10 alone. These data suggest that serum levels of IL-17A are a novel predictive index of HADAS. PMID:27190491

    The study aims to evaluate serum VEGF expression in gastric cancer patients and investigate its relationship with clinicopathological parameters. We also examined the serum VEGF levels in GC patients having received surgery or chemotherapy treatment to assess its predictive and prognostic value as a biomarker. We enrolled 154 GC patients having not received neoadjuvant treatment and 100 healthy controls. In the treatment groups, 13 surgery patients and 15 chemotherapy patients were investigated. 42 chemotherapy patients with different chemotherapy efficacy were recruited as well. The serum VEGF was examined by ELISA. Serum VEGF level was remarkably upregulated in GC group compared with healthy group (p < 0.001). The serum VEGF level of GC group was significantly correlated with tumor cells differentiation degree, clinical stages, tumor infiltration depth, lymph node metastasis, and tumor size. The serum VEGF level of the 1 to 3 days after operation group was much lower than that of the preoperative group (p < 0.001) and the 7 days after operation group (p < 0.001). By contrast, serum VEGF level was decreased significantly after chemotherapy (p = 0.001). Importantly, serum VEGF level in PD+SD group was significantly higher compared to the PR+CR group (p = 0.011). Therefore, serum VEGF was a valuable biomarker in clinically monitoring the condition of GC patients. PMID:27597973

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

    Six cephalosporin antibiotics were administered subcutaneously to mice at a level of 20 mg/kg. The serum levels of each were determined at five time intervals ranging from 5 to 120 min after dosing. Urinary recovery and the presence of active metabolites in mouse urine were determined. The peak serum levels and serum half-lives in mice were found to be positively correlated with the mean effective dose values obtained after lethal challenge with Escherichia coli. The administration of cefazolin and cephanone resulted in the highest serum level and the best protection. Good protection was obtained with cephaloridine despite somewhat lower serum levels. The cephalosporins with the acetoxy side chain (cephalothin, cephapirin, and cephacetrile) showed lower serum levels and the poorest protection. Cefazolin, cephaloridine, and cephalothin serum levels were also determined in dogs, squirrel monkeys, and rabbits. A mixed response was obtained in these species, with cefazolin peak serum levels being highest in rabbits and cephaloridine peak highest in dogs. PMID:15828185

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

    Heat-shock proteins (HSPs) have been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). In this study, we aimed to examine whether the serum levels of HSPs (HSP27, HSP70, and HSP90) are altered in patients with ALS. We included 58 patients diagnosed with ALS and 85 control individuals. Serum HSP levels of patients and controls were determined using enzyme-linked immunosorbent assay. The serum levels of HSP70 and HSP90 were significantly higher in patients than in controls. In contrast, serum levels of HSP27 did not differ significantly between the patient and control groups. Moreover, serum levels of HSP70 and HSP90 in patients remained high throughout the duration of the disease. Taken together, our findings suggest that HSPs might have a role in ALS progression throughout the course of the disease. Further studies are needed to clarify the role of HSPs in the pathogenesis of ALS. PMID:27112486

    Laminin and type-IV collagen constitute a significant portion of the extracellular matrix. The objective of the present study was to evaluate whether the serum concentrations of laminin and type-IV collagen may serve as biomarkers for cutaneous melanoma. Sixty pathologically confirmed melanoma patients were enrolled in the study. Serum laminin and type-IV collagen levels were assessed using an ELISA. Thirty healthy controls were also examined. No significant differences in the baseline serum levels of laminin were identified between melanoma patients and healthy controls (P=0.45). However, the baseline serum levels of type-IV collagen were significantly elevated in melanoma patients compared with those in the control group (P<0.001). Clinical parameters, including patient age, gender, localization of lesion, histopathology, stage of disease, serum lactate dehydrogenase concentrations and responsiveness to chemotherapy were found not to be associated with the serum levels of laminin and type-IV collagen (P>0.05). Furthermore, the serum levels of laminin and type-IV collagen had no prognostic value regarding the outcome for melanoma patients (P=0.36 and P=0.26, respectively). While laminin levels showed no diagnostic value, the serum concentrations of type-IV collagen were indicated to serve as a diagnostic marker in patients with cutaneous melanoma. In conclusion, type-IV collagen levels may be used as a diagnostic marker for cutaneous melanoma, while being void of any prognostic value. PMID:27330797

    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 < 0.001), serum triglyceride (β = 0.001, P < 0.001), CCr (β = -0.003, P = 0.001), hsCRP (β = 0.157, P = 0.001), fibrinogen (β = 0.001, P < 0.001) and BMI (β = 0.02, P = 0.008) independently affected log transformed serum chemerin levels. Higher serum chemerin level was associated with higher level of 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. PMID:27247502

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

    Angiopoietin-like protein 6 (ANGPTL6) is a novel metabolic regulator that modulates energy expenditure as well as glucose and lipid metabolism. Thyroid hormone can induce metabolic changes that are similar to those induced by ANGPTL6. Herein, we investigated whether circulating ANGPTL6 levels change according to thyroid hormone status in humans. We measured the serum levels of ANGPTL6 and metabolic parameters in 150 drug-naïve subjects with overt hyperthyroid, subclinical hyperthyroid, euthyroid, subclinical hypothyroid, or overt hypothyroid status (n=30 in each group). Serum ANGPTL6 levels were significantly higher in patients with overt hypothyroidism than in the other subjects. Women had significantly higher serum levels of ANGPTL6 than men. ANGPTL6 levels correlated positively with thyroid stimulating hormone (TSH), total cholesterol, aspartate aminotransferase, and alanine aminotransferase (ALT) and negatively with serum free thyroxine (T4) level. Multiple stepwise linear regression analysis revealed that sex, TSH, free T4, and ALT were independent predictors of serum ANGPTL6 levels. In summary, serum ANGPTL6 levels increased in patients with a hypothyroid status, and both TSH and free T4 levels are associated with ANGPLT6 levels, suggesting a possible association between thyroid function and ANGPTL6 levels. Whether the upregulated ANGPTL6 level in the hypothyroid status is primarily owing to a direct association or a compensatory mechanism remains to be determined. PMID:26189599

    Administration of 4-8 mg testosterone propionate significantly raised 25-hydroxycalciferol levels in the ultraviolet irradiated rats compared to the ultraviolet irradiated controls, but failed to influence serum 25-hydroxycalciferol levels in the non-irradiated animals. Estradiol benzoate and progesterone did not influence serum 25-hydroxycalciferol levels regardless of the ultraviolet irradiation. These findings implicate that testosterone enhances vitamin D biosynthesis induced by ultraviolet irradiation in rats, in accordance with the clinical observation that males often show higher levels of serum 25-hydroxycalciferol than females.

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

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

    Background Serum selenium levels are lower in critically ill patients as compared with healthy controls. However, there is no data about the difference in serum selenium levels depending on the severity of lung diseases. We aimed to identify the factors associated with low serum selenium levels in critically ill patients with respiratory diseases. Methods A prospective study was performed in 83 patients with respiratory diseases who had admitted to the intensive care unit (ICU) and general wards. We obtained systemic inflammatory markers, nutritional indicators and prognostic factors as the explanatory variables for the outcome of low serum selenium levels. Results Serum selenium levels on admission were lower by 28% in the ICU group as compared with the general ward group (70.0±26.4 and 97.9±20.8 ng/mL, respectively, P<0.001). Low serum selenium levels had a correlation with malnutrition represented by decreases in levels of lymphocyte (R2=0.107, P=0.005) and albumin (R2=0.174, P<0.001). In addition, low serum selenium levels were associated with an increase in baseline C-reactive protein (CRP) (R2=0.059, P=0.041) and APACHE II scores (R2=0.209, P<0.001). Lower albumin levels (P=0.032) and higher APACHE II scores (P=0.046) showed a significant correlation with lower serum selenium levels on multivariate analysis. Conclusions Low serum selenium levels in patients with respiratory diseases have a significant correlation with poor nutritional status and prognosis on admission. PMID:27621861

    Accumulating evidence suggests that oxidative stress is associated with osteoporosis. Serum uric acid (UA) is a strong endogenous antioxidant. Therefore, we investigated the relationship between the serum UA and BMD in Chinese men with T2DM. In this cross-sectional study of 621 men with T2DM, BMDs at lumbar spine (L2–4), femoral neck (FN), and total hip (TH) were measured by dual-energy X-ray absorptiometry (DXA). Serum levels of UA, calcium (Ca), 25-OH vitamin D3 (vitD3), parathyroid hormone (PTH), and creatinine (Cr) were also tested. Data analyses revealed that serum UA levels were positively associated with BMD at all sites (p < 0.05) in men with T2DM after adjusting for multiple confounders. The serum UA levels were positively correlated with body weight (r = 0.322), body mass index (BMI) (r = 0.331), Ca (r = 0.179), and Cr (r = 0.239) (p < 0.001) and were also positively associated with the concentrations of PTH (r = 0.10, p < 0.05). When compared with those in the lowest tertile of UA levels, men with T2DM in the highest tertile had a lower prevalence of osteoporosis or osteopenia (adjusted odds ratio 0.54, 95% confidence interval [CI] 0.31–0.95). These data suggest that higher serum levels of UA are associated with higher BMDs and lower risks of osteoporosis in Chinese men with T2DM. PMID:27022396

    To examines the potential causes of increased levels of calcium in serum with increasing dose of atomic bomb radiation, which was obtained from the previous preliminary analysis, levels of parathyroid hormone (PTH) and calcitonin in serum were examined among 1459 subjects in Hiroshima and Nagasaki. A significant effect of radiation on levels of calcium, PTH and calcitonin in serum was found, even after patients with hyperparathyroidism were excluded. The level of calcium in serum increased with radiation dose; this can be explained partly by the increase in the level of PTH with radiation dose. However, the dose effect on calcium remained even after adjustment for PTH, calcitonin and confounding factors such as renal function, serum albumin level and medication. Parathyroid hormone increased initially by 6.8% per gray, but the dose response leveled off after about 1 Gy. The level of calcitonin increased with radiation dose, probably in part due to feedback mechanisms stimulated by the increase in calcium. However, after adjustment for the level of calcium, the increase in the level of calcitonin with dose was still found. Although the etiological mechanisms of the effect of radiation on serum levels of calcium, PTH and calcitonin are unclear, radiation exposure may affect secretion of PTH and calcitonin and regulation of calcium a long time after atomic bomb exposure. 21 refs., 3 figs., 6 tabs.

    Background Adolescent diet is hypothesized to influence breast cancer risk. We evaluated the long-term effects of an intervention to lower fat intake among adolescent girls on biomarkers that are related to breast cancer risk in adults. Methods A follow-up study was conducted of 230 girls who participated in the Dietary Intervention Study in Children (DISC), in which healthy, prepubertal 8-10 year olds were randomly assigned to usual care or to a behavioral intervention that promoted a reduced fat diet. Participants were 25-29 years old at follow-up visits. All tests of statistical significance are two-sided. Results In analyses that did not take account of diet at the time of the follow-up visit, the only statistically significant treatment group difference was higher bone mineral content (BMC) in intervention group participants compared to usual care group participants; their mean BMCs were 2,444g and 2,377g, respectively. After adjustment for current diet, the intervention group also had statistically significantly higher bone mineral density and luteal phase serum estradiol concentrations. Serum progesterone concentrations and breast density did not differ by treatment group in unadjusted or adjusted analyses. Conclusion Results do not support the hypothesis that consumption of a lower fat diet during adolescence reduces breast cancer risk via effects on subsequent serum estradiol and progesterone levels, breast density or BMD. Impact Additional research is needed to clarify the association of adolescent diet with breast cancer risk and to determine if the results reported here are specific to the DISC intervention or more broadly applicable.

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

    Aim: Osteocalcin is involved in the progression of nonalcoholic fatty liver disease (NAFLD) in animal models and humans. In this study we investigated the relationship between serum osteocalcin levels and NAFLD in postmenopausal Chinese women. Methods: A total of 733 postmenopausal women (age range: 41–78 years) with normal blood glucose levels were enrolled in this cross-sectional study. Women taking lipid-lowering or anti-hypertensive drugs were excluded. Serum osteocalcin levels were assessed using an electrochemiluminescence immunoassay. The degree of NAFLD progression for each subject was assessed through ultrasonography. The fatty liver index (FLI) of each subject was calculated to quantify the degree of liver steatosis. Results: The median level of serum osteocalcin for all subjects enrolled was 21.99 ng/mL (interquartile range: 17.84–26.55 ng/mL). Subjects with NAFLD had significantly lower serum osteocalcin levels (18.39 ng/mL; range: 16.03–23.64 ng/mL) compared with those without NAFLD (22.31 ng/mL; range: 18.55–27.06 ng/mL; P<0.01). Serum osteocalcin levels decreased with incre¬mental changes in the FLI value divided by the quartile (P-value for trend<0.01). The serum osteocalcin levels showed a negative correlation with the FLI values, even after adjusting for confounding factors (standardized β=−0.124; P<0.01). Binary logistic regression analysis identified an individual's serum osteocalcin level as an independent risk factor for NAFLD (odds ratio: 0.951; 95% confidence interval: 0.911–0.992; P=0.02). Conclusion: Serum osteocalcin levels are inversely correlated with NAFLD in postmenopausal Chinese women with normal blood glucose levels. PMID:26567728

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

    Interleukin-6, also named B-cell stimulatory factor, is a glycoprotein with a molecular weight of 26 kDa. Increased serum levels of interleukin-6 (IL-6) are found in several disease conditions. We investigated the importance of a deteriorated kidney function upon IL-6 serum concentrations. No relation was found between serum levels of IL-6 and s-creatinine, r = 0.004. On the other hand, the serum concentration of complement protein factor D and soluble IL-2 receptor showed a good correlation to s-creatinine, r = 0.92 and 0.79, respectively. In conclusion, serum levels of IL-6 are not dependent upon a reduced kidney function. PMID:18475461

    To assess the effects of automobile exhaust on human health, we determined serum concentrations of total immunoglobulin E and hyaluronate in 185 schoolchildren who lived in a district that contained major roads. Serum immunoglobulin E levels were elevated in children who had asthma or wheezing, but levels did no t differ with respect to distance of their homes from the major roads. Serum hyaluronate levels were higher in children who lived less than 50 m from the roadside, compared with children who resided a greater distance from roads. The difference, however, was significant only in a subgroup of children in whom immunoglobulin E levels exceeded 250 IU/ml. Our results suggest that serum hyaluronate levels in children reflect the effects of traffic-related air pollution. Children with high immunoglobulin E levels appeared to be particularly susceptible to the effects of automobile exhaust. 34 refs., 2 figs., 3 tabs.

    The life style of young adults has been receiving attention with a view to its improvement to preventing coronary heart diseases (CHD) in later life. In this study, for determining the influence of different life styles on the serum triglyceride level, we carried out surveys and laboratory studies on the relationships of the nutritional intake, physical activity, and cigarette smoking and alcohol consumption of young adults with their serum triglyceride levels. The nutritional survey indicated a significant correlation between the serum triglyceride level and carbohydrate intake (p < 0.01). In the survey of physical activity, a significant inverse correlation was found between the energy expenditure per kg body weight and the serum triglyceride level (p < 0.05). No significant relationship was found of smoking or drinking with the serum triglyceride level. The body mass index was found to have effects on both the serum triglyceride and total cholesterol levels. Of the factors examined, carbohydrate intake and energy expenditure per kg body weight had the greatest effects on the serum triglyceride level. Considering the trend for young people to consume large quantities of carbonated drinks, in which most of carbohydrate is sucrose, we tested the affect of a high carbohydrate diet on one group of subjects and found that it caused a significant increase in the serum triglyceride level (p < 0.05). Another group for whom a mild exercise regimen was prescribed showed slight, but not significant decrease in the serum triglyceride level. These results suggest that at least optimal nutrition and physical activity including weight control during adolescence are important for preventing CHD. PMID:7940529

    Although coronary heart disease remains a leading cause of death and disability in old age, the relationship of serum cholesterol level to risk of coronary heart disease in old age is controversial. Data for 2,388 white persons aged 65-74 who participated in the National Health and Nutrition Examination Survey (NHANES) I Epidemiologic Follow-up Study (NHEFS) were examined to determine the relationship of serum cholesterol level to coronary heart disease incidence and whether activity level would modify this relationship. While there was no overall relationship between serum cholesterol level and coronary heart disease risk in either men or women, the relationship between serum cholesterol level and coronary heart disease differed within activity groups. For persons who were more active, serum cholesterol level was associated with a graded increase in risk of coronary heart disease, from 1.3 (95% CI 0.7, 2.3) in those with serum cholesterol level of 4.7-5.1 to 1.7 in those with serum cholesterol level of 6.2 mmol/L or more (95% CI 1.0, 2.7), when compared with those with serum cholesterol level below 4.7. For the least active persons, all levels of cholesterol were associated with a significant inverse relative risk, including cholesterol of 6.2 mmol/L or more (Relative risk = 0.4 (95% CI 0.2, 0.7]. These data suggest that factors such as activity level may modify the serum cholesterol-coronary heart disease association in old age. The serum cholesterol-coronary heart disease association in more active older persons resembles that seen in younger populations, whereas the association in less active persons is that of serum cholesterol level and risk of cancer or death. The modification of the serum cholesterol-coronary heart disease association by activity level may have implications for appropriate clinical management as well as appropriate design of research studies of this association.

    Aim. To investigate the effect of exenatide treatment on serum ghrelin levels in obese female patients with type 2 diabetes mellitus. Methods. Fourteen female patients with type 2 diabetes mellitus being treated with metformin and exenatide were enrolled. A mixed meal test was applied to the patients while continuing with their daily medications. Blood samples were taken before and at 60, 120, and 180 minutes following mixed meal test to measure serum total ghrelin, glucose, and insulin levels. The following week, exenatide treatment of the patients was paused for 24 hours and the same experimental procedures were repeated. Results. Serum ghrelin levels were suppressed significantly at 180 minutes with exenatide treatment compared with baseline (294.4 ± 57.5 versus 234.5 ± 59.4 pg/mL) (p < 0.001). Serum ghrelin levels at 180 minutes were statistically different when percentage change in serum ghrelin levels after mixed meal tests with and without exenatide usage were compared (p = 0.001). Estimated total area under the curve values for serum ghrelin concentrations was also significantly lower with exenatide compared with omitted treatment (p = 0.035). Conclusion. These results suggest that the effect of exenatide on weight loss may be related with the suppression of serum ghrelin levels, which is an orexigenic peptide. PMID:26998491

    Cryptorchidism is the most common congenital birth defect in boys and affects about 2–4% full-term male neonates. Its etiology is multifactorial. Purpose. To evaluate the serum bisphenol A (BPA) levels in boys with cryptorchidism and healthy boys and to assess the risk of environmental exposure to BPA using the authors' questionnaire. The data were acquired from a study on boys with cryptorchidism (n = 98) and a control group (n = 57). Prior to surgery, all patients had BPA serum levels evaluated. The size, position, rigidity of the testis, and abnormality of the epididymis of the undescended testis were assessed. Parents also completed a questionnaire on the risks of exposure to BPA in everyday life. Results. The testes in both groups were similar in size. The turgor of the undescended testis in the group of boys with cryptorchidism was decreased. Free serum BPA level in cryptorchid boys and in the control group was not statistically significant (p > 0.05). The conjugated serum BPA level in cryptorchid boys and in the control group was statistically significant (p ≤ 0.05). Total serum BPA level in cryptorchid boys and in the control group was statistically significant (p < 0.05). Serum total BPA level was related with a positive answer about problems with conception (p < 0.02). Conclusion. Our study indicated that high serum BPA was associated with cryptorchidism.

    Chronic obstructive pulmonary disease (COPD) is associated with cognitive decline, but the molecular link between COPD and dementia or Alzheimer's disease (AD) remains unclear. This study was aimed to investigate whether serumlevels are correlated with COPD. 77 cognitively normal COPD patients and 45 age- and gender-matched normal controls were admitted to the study. Serum Aβ40 and Aβ42 levels were measured using ELISA kits. Serum C-reactive protein (CRP), interleukin 6 (IL-6), and procalcitonin (PCT) measurements were done using standard laboratory methods. Pulmonary function tests were performed to assess the pulmonary function and determine the degree of lung damage. Significantly increased levels of serum Aβ40, Aβ42, and total Aβ levels were found in patients with COPD in comparison with normal controls. In COPD patients, serumlevels were higher in subjects with serum CRP, IL-6, and PCT upper the limit of normal. Moreover, serumlevels were dramatically higher in COPD patients with worse pulmonary function. Our study suggests that cognitively normal COPD patients may undergo AD-related pathological changes, and COPD might facilitate AD-type pathogenesis. PMID:26243505

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

    Objective: To evaluate the effect of long-term ethanol extract of Lepidium meyenii (Maca) on serum hormone levels in ovariectomized (OVX) rats and compare them with the effect of diethylstilbestrol. Materials and Methods: Fifty female Sprague-Dawley rats were ovariectomized or sham operated. Both sham and OVX control groups (n = 10, respectively) received the vehicle. The remaining OVX rats were oral administrated with ethanol extract of Maca (0.096, or 0.24g/kg; n = 10, respectively) and diethylstilbestrol (0.05 mg/kg; n = 10). The treatment continued for 28 weeks. At week 12 and week 28, the blood of rats was collected and serum hormone levels, including estradiol (E2), testosterone (T) and follicle-stimulating hormone (FSH) were measured by radioimmunoassay. Results: At week 12, the levels of serum E2 were slightly higher in Maca groups than that in OVX group; T levels were significantly decreased; and FSH levels were advanced slightly in Maca groups than that in sham group. After 28 weeks administration, serum E2 levels in Maca-treated animals did not differ significantly from sham control, the low dose of Maca increased serum E2 levels, and Maca prevented increase in serum FSH levels compared with OVX group. Conclusions: Long-term Maca supply modulates endocrine hormone balance in OVX rats, especially it decreases enhanced FSH levels. It is proposed that Maca may become a potential choice for postmenopausal women. PMID:25097281

    Many studies have investigated the association between serum/hair zinc levels and breast cancer, but the results were inconsistent. To compare the serum and hair zinc levels in women with breast cancer and controls, we conducted a systematic literature search of PubMed, Web of Science, Cochrane Library and Embase to identify relevant studies with publication dates up through November 2014. Based on a random effects model, summary standard mean differences (SMDs) and the corresponding 95% confidence intervals (CIs) were used to compare the serum and hair zinc levels in women with breast cancer and controls. Fourteen studies that investigated serum zinc levels and seven studies that assessed hair zinc levels were included. Our study observed no difference in serum zinc levels between breast cancer cases and controls (SMD (95%CI): −0.65[−1.42,0.13]). However, we determined that hair zinc levels were lower in women with breast cancer compared with those of controls (SMD (95%CI): −1.99[−3.46, −0.52]). In conclusion, this study was the first to provide evidence that hair zinc levels in female breast cancer patients are lower than in controls; however, there was no significant difference in serum zinc levels between female breast cancer patients and controls.

    Serum transthyretin (TTR) levels are reduced in familial amyloidotic polyneuropathy (FAP). A single study of patients with senile systemic amyloidosis (SSA) in Sweden found that those individuals also had a significantly lower mean serum TTR concentration than age- and gender-matched controls. To determine if the same phenomenon prevailed in an ethnically more heterogeneous population, we compared the serum TTR levels, as determined by ELISA, in 45 documented SSA patients with congestive heart failure, 20 AL patients with congestive heart failure and population controls. Serum TTR concentrations in the controls were influenced in a statistically significant manner by age, gender and ethnicity. Although it is unlikely that such differences are clinically relevant, they must be considered when assessing the meaning of serum TTR concentrations in any clinically defined population. The serum concentrations in patients with SSA did not differ from age, gender and ethnically matched controls or from a group of AL patients with significant clinical cardiac involvement. We also compared TTR concentrations in 12 African-Americans carrying the TTR V122I allele with those in 826 African-Americans who were homozygous wild type at the TTR locus. The TTR V122I carriers had significantly lower serum TTR concentrations than appropriate controls even though the majority of such individuals had not reached the age of clinical or anatomic risk, i.e. over 60. Thus, as in carriers of other TTR mutations the serum TTR level is lower than normal, despite having a much later appearance of clinical disease. PMID:19065297

    Protease-activated receptor-1 (PAR-1) has a significant role in the pathogenesis of various malignancies and its expression mainly affects the survivals of cancer patients. The aim of the present study was to determine the clinical significance of the serum concentrations of PAR-1 in patients with gastric carcinoma. A total of 63 pathologically confirmed gastric cancer patients were enrolled in this study, with a median age of 62 years. Serum PAR-1 concentrations were determined by the enzyme-linked immunosorbent assay method and no significant difference in the baseline serum PAR-1 concentrations was found between patients and normal controls (P=0.5). The investigated clinical variables, including patient age, gender, localization of lesion, histology, grade of pathology, disease stage and serum tumor markers (lactate dehydrogenase, carcinoembryonic antigen and carbohydrate antigen 19-9) were not correlated with serum PAR-1 levels (P>0.05). Furthermore, no association was identified between the serum PAR-1 level and chemotherapy responsiveness (P=0.43). Serum PAR-1 level also had no prognostic role for survival (P=0.27). In conclusion, the serum PAR-1 concentration has no diagnostic, predictive and prognostic values in gastric cancer patients. PMID:27073639

    Background: Hyperprolactinemia may reflect neuroendocrine stress reaction against acute coronary syndromes. Aim: The aim of the present study was evaluation of the serum prolactin level in the acute myocardial infarction (MI) regarding the current pharmacotherapy in management of MI. Setting and Design: Cross-sectional clinical based study. Subjects and Methods: This cross-sectional clinical study involved all patients with acute MI in a coronary care unit, a total number of 44 patients (45% males and 55% females) with age ranged from 40 to 75 years. A full history for modifiable risk factors and current therapy with aspirin, clopidogrel and or metformin, all patients are nonsmokers. The anthropometric measurements; for estimations of body mass index (kg/m2), electrocardiography was obtained. Fasting blood samples were taken in the morning from all patients and the sera used for estimations of routine investigation and determination of ischemic cardiac biomarkers like cardiac troponin I (cTnI) and serum prolactin level. Results: This study shows a significant increase in the serum prolactin in acute MI as compared with the control. In acute MI serum cTnI elevation was correlated with serum prolactin increments. In metformin-treated group, there was a lowest prolactin serum level. Conclusions: Serum prolactin level increased in acute MI, and positively correlated with cardiac troponin level and reflects underlying cardiovascular complications. PMID:26904472

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

    H1-receptor inhibiting drugs, namely loratadine and cetirizine, were frequently used in treatment of chronic urticaria. Urticarial weal and flare reactions, a neurogenic reflex due to neuropeptides, were reported to be more effectively inhibited by cetirizine than loratadine. The aim of this study was to determine and compare the effects of systemic loratadine and cetirizine treatments on serum levels of selected neuropeptides in chronic urticaria. Treatment groups of either systemic loratadine or cetirizine (10 mg/d), consisting of 16 and 22 patients, respectively, were included. Serum levels of stem cell factor (SCF), neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), nerve growth factor (NGF), vasoactive intestinal peptide (VIP), and substance P (SP) were detected before and after one week of treatment with antihistamines. Serum NPY and VIP levels were significantly decreased when compared before and after treatment with antihistamines (P < 0.001 and P < 0.01, respectively). SCF and NGF values were also decreased after antihistamine treatment (P < 0.05). Post-treatment levels of CGRP were significantly higher compared with pretreatment values, while no significant difference was detected between pre and post treatment levels of SP. Cetirizine was significantly more effective than loratadine on lowering serum levels of SCF among the other neuropeptides. Systemic loratadine and cetirizine treatments in patients with chronic urticaria precisely caused variations in serum levels of neuropeptides. The predominant effect of cetirizine compared to loratadine on reducing serum SCF levels might be explained with anti-inflammatory properties of cetirizine. PMID:25209952

    Background The prevalence of diabetes in China is increasing rapidly. However, scarce data are available on serum electrolyte levels in Chinese adults with diabetes, especially in those with cardiovascular complications. This study measured serum electrolyte levels and examined their relationship with macrovascular complications in Chinese adults with diabetes. Methods The three gender- and age-matched groups were enrolled into this analysis, which were 1,170 subjects with normal glucose regulation (NGR), 389 with impaired glucose regulation (IGR) and 343 with diabetes. Fasting plasma glucose (FPG), 2-hour post-load plasma glucose (2hPG), glycosylated hemoglobin A1c (HbA1c) and serum electrolyte levels were measured. Data collection included ankle brachial index results. Results Serum sodium and magnesium levels in the diabetes group were significantly decreased compared to the NGR group (sodium: 141.0 ± 2.4 vs. 142.1 ± 2.0 mmol/l; magnesium: 0.88 ± 0.08 vs. 0.91 ± 0.07 mmol/l, all P < 0.01), while the serum calcium level was significantly increased (2.36 ± 0.11 vs. 2.33 ± 0.09 mmol/l, P < 0.01). Multiple linear regression showed that serum sodium and magnesium levels in the diabetes group were negatively correlated with FPG, 2hPG and HbA1c (sodium: Std β = −0.35, -0.19, -0.25; magnesium: Std β = −0.29, -0.17, -0.34, all P < 0.01), while the serum calcium level was positively correlated with HbA1c (Std β = 0.17, P < 0.05). In diabetic subjects, serum sodium, magnesium and potassium levels were decreased in the subjects with the elevation of estimated glomerular filtration rates (P < 0.05). ANCOVA analysis suggested that serum magnesium level in subjects with diabetic macrovascular complications was significantly decreased compared with diabetic subjects without macrovascular complications after the effect of some possible confounding being removed (P < 0.05).

    Background Beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. The purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. Materials and Methods This descriptive-cross sectional study was performed on 90 children aged 6-16 years old with beta-thalassemia. Body Mass Index (BMI ) were meuseurd in all patients and then, after collecting the samples, leptin and thyroid hormones levels of the serum were measured in the patients with thalassemia via ELISA method. Then, all data was analyzed by Pearson correlation test, and x2 statistical tests and P < 0.05 was considered as a significant difference. Results The mean of body mass index and serum leptin level in the patients group was 16.58±2.43 and 1.521 ±2. 49, respectively. The mean serum levels of thyroxin (T4), triiodothyronine (T3), and thyroid- stimulating hormone (TSH) in patient's groups were7.94 ±3.56, 1.28 ± 0.46, and 2.85 ±3. 44, respectively. There was significant correlation between serum leptin levels and T4 in patients with major thalassemia; also there was no significant correlation between serum leptin level and T3and TSH. There was a significant correlation was between the leptin serum level and BMI in patients (P value=0.008). Conclusion The results of this study demonstrated that in patients with major thalassemia, there was significant correlation between serum leptin level and thyroxin hormone. Leptin level has more relationship with thyroxin than thyroid- stimulating hormone. PMID:24575288

    Background: Sperm dysfunction is one of the main causes of male infertility. Petroselinum crispum (P. crispum) is a member of umbelliferae family that contains different vitamins and minerals and has numerous therapeutic properties. The aim of this study was to evaluate P. crispum effect on sperm parameters, testis tissue and serum nitric oxid levels in mice. Materials and Methods: Hydroalcoholic extract of P. crispum was prepared and administered intraperitoneally (0,100, 150 and 200 mg/kg) to 40 mice, which were divided into four groups (n = 10), one control group and three experimental groups, for 14 consequent days. The sperm parameter such as motility, sperm count, morphology, and seminiferous tubules diameter, and weight of prostate and testis, and serum nitric oxide levels were analyzed. Results: P. crispum administration (100, 150 and 200 mg/kg) significantly increased mean percentage of sperm motility, testis and prostate weight and serum nitric oxide compared to the control group (P < 0.05). However, no significant effect was reported for different doses of P. crispum extract on sperm parameters. Conclusion: Administrating hydroalcoholic extract of P. crispum has positive effects on some reproductive parameters. PMID:25789266

    Salival and serum melatonin levels after melatonin ingestion were measured by gas chromatography-mass spectrometry. Ingestion of 3 mg melatonin caused a marked increase in serum melatonin (3561+/-1201 pg/mL) within 20 min, followed by a gradual decrease, but the level still remained higher than the basal level at 240 min after the ingestion. The saliva melatonin 60 min after the ingestion showed the highest level (1177+/-403 pg/mL) which was one-third of the plasma level. The saliva melatonin level was highly correlated with the serum level throughout the experimental period (r=0.82, P=0.0001). These data indicate that the measurement of saliva melatonin level may be a suitable indicator for the melatonin secretion into general circulation. PMID:9628188

    Aims To evaluate the serum level of vascular endothelial growth factor (VEGF) in a group of chronic ketamine abusers in comparison to healthy controls. Methods Eighty-one ketamine abusers who were hospitalized for the treatment of ketamine dependence and 39 healthy controls were recruited. Serum VEGF level was measured by enzyme linked immunosorbent assay (ELISA). Psychopathological symptoms were assessed using Positive and Negative Syndrome Scale (PANSS), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). Results Serum level of VEGF was significantly lower in chronic ketamine abusers compared to healthy controls (64.6 ± 42.1 vs. 92.4 ± 59.4 pg/ml, F = 7.243, p = 0.008). Conclusions Serum level of VEGF decreased in chronic ketamine abusers compared to healthy controls. PMID:26003336

    Background The association between systemic sclerosis and pulmonary arterial hypertension (PAH) is well recognized. Vascular endothelial growth factor (VEGF) has been reported to play an important role in pulmonary hypertension. The aim of the present study was to examine the relationship between systolic pulmonary artery pressure, clinical and functional manifestations of the disease and serum VEGF levels in systemic sclerosis. Methods Serum VEGF levels were measured in 40 patients with systemic sclerosis and 13 control subjects. All patients underwent clinical examination, pulmonary function tests and echocardiography. Results Serum VEGF levels were higher in systemic sclerosis patients with sPAP ≥ 35 mmHg than in those with sPAP < 35 mmHg (352 (266, 462 pg/ml)) vs (240 (201, 275 pg/ml)) (p < 0.01), while they did not differ between systemic sclerosis patients with sPAP < 35 mmHg and controls. Serum VEGF levels correlated to systolic pulmonary artery pressure, to diffusing capacity for carbon monoxide and to MRC dyspnea score. In multiple linear regression analysis, serum VEGF levels, MRC dyspnea score, and DLCO were independent predictors of systolic pulmonary artery pressure. Conclusion Serum VEGF levels are increased in systemic sclerosis patients with sPAP ≥ 35 mmHg. The correlation between VEGF levels and systolic pulmonary artery pressure may suggest a possible role of VEGF in the pathogenesis of PAH in systemic sclerosis. PMID:19426547

    Painful bone disease, characterized by patchy osteomalacia and inactive bone, can develop in patients treated with total parenteral nutrition for more than 3 months. Serum levels of 1 alpha,25-dihydroxyvitamin D (1 alpha, 25(OH)2D), 24,25-dihydroxyvitamin D and 25-hydroxyvitamin D were measured in seven adults and five children treated with parenteral nutrition for 9 to 60 months. Serum levels of 1 alpha, 25(OH)2D were markedly reduced, while levels of 25-hydroxyvitamin D and 24,25-dihydroxyvitamin D were normal. Serum calcium and phosphorus levels were normal or slightly increased, and immunoreactive parathyroid hormone levels were normal or low. Renal function was normal or minimally reduced. Skeletal symptoms disappeared and serum 1 alpha, 25(OH)2D levels rose to normal in one patient when nutrient infusions were discontinued for 6 weeks. Removal of calcium from the nutrient solution for 2 to 4 days was associated with no change in serum 1 alpha, 25(OH)2D in two patients. The cause of the reduction in serum levels of 1 alpha, 25(OH)2D and its role in the pathogenesis of bone disease in these patients remain uncertain. PMID:6786151

    Uric acid (UA), the final product of purine metabolism, has been reported to be reduced in patients with various neurological disorders and is considered to be a possible indicator for monitoring the disability and progression of multiple sclerosis. However, it remains unclear whether there is a close relationship between UA and myasthenia gravis (MG), or whether UA is primarily deficient or secondarily reduced because of its peroxynitrite scavenging activity. We investigated the correlation between serum UA levels and the clinical characteristics of MG. We assessed 338 serum UA levels obtained in 135 patients with MG, 47 patients with multiple sclerosis, and 156 healthy controls. In addition, we compared serum UA levels when MG patients were stratified according to disease activity and classifications performed by the Myasthenia Gravis Foundation of America, age of onset, duration, and thymus histology (by means of MRI or computed tomography). MG patients had significantly lower serum UA levels than the controls (P<0.001). Moreover, UA levels in patients with MG were inversely correlated with disease activity and disease progression (P=0.013). However, UA levels did not correlate significantly with disease duration, age of onset, and thymus histology. Our findings suggest that serum level of UA was reduced in patients with MG and serum UA might be considered a surrogate biomarker of MG disability and progression. PMID:26836463

    Phosphorus (P) is of vital importance for many aspects of metabolism, including bone mineralization, blood buffering, and energy utilization. In order to identify molecular routes affecting intrinsic P utilization, we address processes covering P intake, uptake, metabolism, and excretion. In particular, the interrelation of bone tissue and immune features is of interest to approximate P intake to animal's physiology and health status. German Landrace piglets received different levels of digestible phosphorus: recommended, higher, or lower amounts. At multiple time points, relevant serum parameters were analyzed and radiologic studies on bone characteristics were performed. Peripheral blood mononuclear cells were collected to assess differential gene expression. Dietary differences were reflected by serum phosphorus, calcium, parathyroid hormone, and vitamin D. Bone reorganization was persistently affected as shown by microstructural parameters, cathepsin K levels, and transcripts associated with bone formation. Moreover, blood expression patterns revealed a link to immune response, highlighting bidirectional loops comprising bone formation and immune features, where the receptor-activator of NF-κB ligand/receptor-activator of NF-κB kinase system may play a prominent role. The modulated P supplementation provoked considerable organismal plasticity. Genes found to be differentially expressed due to variable P supply are involved in pathways relevant to P utilization and are potential candidate genes for improved P efficiency. PMID:26962023

    The association of alcohol intake with total serum IgE concentrations in humans is discussed in the present review. The possible relationship of regular alcohol intake with both the risk of allergic sensitization and serum allergen-specific IgE values is also reviewed. Several studies consistently show that total serum IgE concentrations are increased in alcoholics when compared with healthy controls. Total serum IgE levels decrease after ethanol abstinence in alcoholics. Total serum IgE is increased in moderate alcohol consumers with respect to abstainers. Alcohol consumption in mothers may be associated with increased cord blood IgE levels in their offspring. IgE elevation in alcohol consumers is independent of potential confounders such as age, sex, liver disease, cigarette smoking or atopic status. Experimental studies in animals further support that ethanol administration is followed by an increase in serum IgE concentrations. In atopic patients, regular alcohol consumption is associated with increased serum specific IgE levels against some aeroallergens. Preliminary reports suggest that alcohol intake is associated to variable risk of sensitization to some aeroallergens. The possible mechanisms of alcohol-induced alterations in IgE levels and IgE-mediated diseases are discussed. PMID:11991851

    IgG, IgA, IgM, and transferrin levels were measured in sera from a group of children who had been subjected to splenectomy in the previous 10 years. In those children splenectomized for hereditary spherocytosis, idiopathic thrombocytopenic purpura, or traumatic rupture, mean IgM levels were significantly lower and mean transferrin levels were significantly higher than in sera from control children. Children splenectomized for thalassaemia major had a significantly raised mean IgG level, while children splenectomized for portal hypertension had a raised mean IgA level. However, IgG and IgA levels in patients who had suffered splenic rupture did not differ from control values. The finding of high transferrin levels after splenectomy supports the concept of an immunological function for this protein in addition to its iron-binding capacity. PMID:4191614

This group was used to determine the cut-off for preoperative CA19-9 serum levels as a surrogate marker for micrometastases. Then 187 node-negative T1 to T4 patients were selected to validate the predictive value of this CA19-9 threshold. Results Patients with micrometastases had significantly higher preoperative CA19-9 serum levels compared to patients without micrometastases (p = 0.046). CA19-9 serum levels were significantly correlated with tumour site, tumour diameter, and perineural invasion. Although not reaching significance, subgroup analysis showed better five-year survival rates for patients with CA19-9 serum levels below the threshold, compared to patients with CA19-9 serum levels above the cut-off. The cumulative survival for T2 to T4 node-negative patients was significantly better with CA19-9 serum levels below the cut-off (p = 0.04). Conclusions Preoperative CA19-9 serum levels can be used to predict higher risk for haematogenous spread and micrometastases in node-negative patients. However, CA19-9 serum levels lack the necessary sensitivity and specificity to reliably predict micrometastases. PMID:27247553

    Background: Leptin is secreted by adipose tissue and decreases appetite. However, the role of leptin in the pathogenesis of hemodialysis (HD)-related malnutrition has not been fully evaluated. Objectives: The aim of study was to investigate the association between the serum leptin levels, serum C-reactive protein (CRP) levels, and nutritional status in hemodialysis patients. Patients and Methods: This analytical descriptive study included 45 hemodialysis patients and 40 healthy subjects. Biochemical parameters and serum leptin levels were measured. The nutritional status was evaluated using a food frequency questionnaire (FFQ) and the calculation of the body mass index (BMI). Results: Serum leptin (P < 0.05) and albumin (P < 0.0001) levels and BMI (P < 0.001) of HD patients were significantly lower, while CRP levels were significantly higher than those of controls (P < 0.0001). HD patients consumed the lower daily servings of the food groups compared to the control subjects (P < 0.0001). A significant positive correlation between serum levels of leptin and albumin and BMI was demonstrated. No significant correlations were identified between leptin level, CRP level, and other variables. Conclusions: The findings suggest that low levels of leptin may be a contributory factor for malnutrition in HD patients. Further studies are required to ascertain the significance of leptin levels in relation to nutritional factors in hemodialysis patients. PMID:26430525

    Introduction:There are many ideas concerning the etiology and pathogenesis of preeclampsia including endothelial dysfunction, inflammation and angiogenesis. Elevated levels of total homocysteine (Hcy) and lipoprotein (a) [Lp(a)] are risk factors for endothelial dysfunction. This study aimed to evaluate the effect of high dose folic acid (FA) on serum Hcy and Lp(a) concentrations with respect to methylenetetrahydrofolate reductase (MTHFR) polymorphisms 677C→T during pregnancy. Methods: In a prospective uncontrolled intervention, 90 pregnant women received 5 mg FA supplementation before pregnancy till 36th week of pregnancy. The MTHFR polymorphisms 677C→T, serum lactate dehydrogenase activity, urine protein and creatinine concentrations were measured before starting folic acid administration. Serum levels of Hcy and Lp(a) were determined before and after completion of folic acid supplementation period. Results: Supplementation of the patients with FA for 36 week decreased the median (minimum– maximum) levels of serum Hcy from 11.40 μmol/L (4.40-28.70) to 9.70 (1.60-20.80) μmol/L (p=0.001). There was no significant change in serum Lp(a) after FA supplementation (p=0.17). The overall prevalence of genotypes in pregnant women that were under study for MTHFR C677T polymorphism was 53.3% CC, 26.7% CT and 20.0% TT. There was no correlation between decreasing level of serum Hcy in the patients receiving FA and MTHFR polymorphisms. Conclusion:Although FA supplementation decreased serum levels of Hcy in different MTHFR genotypes, serum Lp(a) was not changed by FA supplements. Our data suggests that FA supplementation effects on serum Hcy is MTHFR genotype independent in pregnant women. PMID:26929921

    Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated. Patients who underwent coronary artery bypass or valve surgery at Yonsei University Health System from January 2013 to December 2014 were enrolled. The patients were divided into 3 groups based on preoperative serum bicarbonate levels, which represented group 1 (below normal levels) <23 mEq/L; group 2 (normal levels) 23 to 24 mEq/L; and group 3 (elevated levels) >24 mEq/L. The primary outcome was the predicated incidence of AKI 48 hours after cardiac surgery. AKI was defined according to Acute Kidney Injury Network criteria. Among 875 patients, 228 (26.1%) developed AKI within 48 hours after cardiac surgery. The incidence of AKI was higher in group 1 (40.9%) than in group 2 (26.5%) and group 3 (19.5%) (P < 0.001). In addition, the duration of postoperative stay in a hospital intensive care unit (ICU) was longer for AKI patients and for those in the low-preoperative-serum-bicarbonate-level groups. A multivariate logistic regression analysis showed that low preoperative serum bicarbonate levels were significantly associated with AKI even after adjustment for age, sex, hypertension, diabetes mellitus, operation type, preoperative hemoglobin, and estimated glomerular filtration rate. In conclusion, low serum bicarbonate levels were associated with higher incidence of AKI and prolonged ICU stay. Further studies are needed to clarify whether strict correction of bicarbonate levels close to normal limits may have a protective

    Background: Previous studies suggested that zinc level was related to a certain diabetic microvascular complication. However, the relationship between zinc level and all the microvascular complications in type 2 diabetic patients remains unknown. The purpose of this study was to analyze the relationship between zinc level and each diabetic microvascular complication and identify the features related to low serum zinc level. Methods: We included the hospitalized patients with type 2 diabetes (T2D) at our department from May 30, 2013 to March 31, 2014. We initially compared the serum zinc levels between patients with specific microvascular complications and those without. We then analyzed the association between zinc level and each microvascular complication. Furthermore, we identified the unique features of patients with high and low serum zinc levels and analyzed the risk factors related to low zinc level. Results: The 412 patients included 271 with microvascular complications and 141 without any microvascular complications. Serum zinc level was significantly lower in patients with diabetic retinopathy (P < 0.001), diabetic nephropathy (DN, P < 0.001), or diabetic peripheral neuropathy (P = 0.002) compared with patients without that specific complication. Lower zinc level was an independent risk factor for DN (odds ratio = 0.869, 95% confidence interval = 0.765–0.987, P < 0.05). The subjects with lower serum zinc level had manifested a longer duration of diabetes, higher level of hemoglobin A1c, higher prevalence of hypertension and microvascular complications, and lower fasting and 2-h C-peptide levels. Conclusions: Lower serum zinc level in T2D patients was related to higher prevalence of diabetic microvascular complications, and represented as an independent risk factor for DN. Patients with lower zinc level were more likely to have a longer duration of diabetes, poorer glucose control, and worse β-cell function. PMID:26668140

    BACKGROUND: Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. AIM: To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association with the response to antipsychotic treatment. MATERIAL AND METHODS: In this clinical prospective study were included 60 patients with schizophrenia and 40 healthy age and sex matched control subjects. Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. For the purposes of the study, the examined group was divided in two subgroups: responders and nonresponders. Serum cortisol and DHEA-S levels were measured at baseline in all participants and after 3 and 6 weeks of the antipsychotic treatment in patients with schizophrenia. RESULTS: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels in comparison to the control group. Responders had significantly higher serum cortisol and DHEA-S levels compared with nonresponders. CONCLUSION: Elevated serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia and they may be related to positive response to antipsychotic treatment in patients with schizophrenia.

    AIM: To investigate the association between serum alpha-fetoprotein (AFP) levels and fatty liver disease (FLD) in a Chinese population. METHODS: A cross-sectional study was performed among subjects who presented for a health examination at the First Affiliated Hospital, College of Medicine, Zhejiang University in 2013. FLD was diagnosed based on an ultrasonography examination. Serum AFP levels were measured with a chemiluminescence immunoassay. RESULTS: Of the 9800 subjects enrolled, 2601 were diagnosed with FLD. Subjects with FLD had higher serum AFP levels than those without the disease. Subjects with high serum AFP levels had a higher prevalence of FLD, metabolic syndrome, and its components. Univariate logistic analysis showed that elevated serum AFP levels were associated with an increased risk of FLD (OR = 1.057, 95%CI: 1.031-1.084). However, after adjusting for covariates, AFP no longer remained significantly associated with the risk factors for FLD. CONCLUSION: Our results suggest that serum AFP levels are significantly associated with FLD and that AFP acts as a cofactor, but not as an independent factor, for FLD. PMID:25206293

    Background: Hemorrhagic Transformation (HT) of Ischemic Stroke (IS) is a detrimental complication. This study investigated the association between serum ferritin level and HT in patients with massive IS of middle cerebral artery. Methods: Thirty patients with massive IS of middle cerebral artery were enrolled in this prospective cohort study. They were divided into two groups based on the serum ferritin level, lower or greater than 164.1ng/ml at the first 24 hours after admission. To investigate the incidence of HT in the two groups, we observed them for two weeks. Results: During the two- week observation, the incidence of HT was two persons (13.3%) in the group with the serum ferritin level of lower than 164.1ng/ml, and eight persons (53.3%) in the other group. This difference was statistically significant between the two groups (p=0.02). The relative risk of HT was 4 (95% CI: 1.012- 15.8) in the patients with massive IS of middle cerebral artery and the serum ferritin level greater than 164.1ng/ml. Conclusion: This study revealed that the serum ferritin level greater than 164.1ng/ml in the first 24 hours after admission is a reasonably important predictor for HT of IS. Conducting studies on factors affecting the serum ferritin level are suggested. PMID:27493907

    Observational and experimental studies have produced inconsistent evidence about the association of serum levels of B-type natriuretic peptide (BNP) with anthracycline-induced cardiotoxicity (AIC). Therefore, the current meta-analysis examined the association between serum BNP levels and AIC by using data from high quality studies published in peer-reviewed journals. Relevant studies were identified through literature searches of China National Knowledge Infrastructure (CNKI), Web of Science, PubMed, Google Scolar and China BioMedicine (CBM). STATA software was used in this meta-analysis for statistical analysis. In addition, the crude standardized mean difference (SMD) with 95% confidence interval (CI) for the highest vs. the lowest category of serum BNP levels was calculated. A total of 8 independent case-control studies, containing 126 AIC patients and 569 healthy controls, were included for the current meta-analysis. The results indicated a significant difference in serum BNP levels between the cardiotoxic group and normal group, with respect to post-treatment and pretreatment with anthracyclines. Specifically, the serum levels of BNP increased remarkably after treatment with anthracyclines in the cardiotoxic group, compared with the normal group. No publication bias was detected in this meta-analysis. The findings of the present study provide strong evidence that serum BNP levels may be associated with AIC. PMID:27123140

    Purpose Dutasteride and finasteride are 5α-reductase inhibitors that dramatically decrease serum levels of dihydrotestosterone. Because androgens affect bone, lipids, hematopoiesis, prostate and sexual function, we determined the impact of 5α-reductase inhibitors on these end points. Materials and Methods We conducted a randomized, double-blinded, placebo controlled trial of 99 men 18 to 55 years old randomly assigned to receive 0.5 mg dutasteride (33), 5 mg finasteride (34) or placebo (32) daily for 1 year. Bone mineral density was measured at baseline, after 1 year of treatment and 6 months after drug discontinuation. In addition, markers of bone turnover, fasting serum lipoprotein concentrations, hemoglobin and prostate specific antigen were measured at baseline, after 26 and 52 weeks of treatment, and again 24 weeks after drug discontinuation. Sexual function was assessed at these points by a validated questionnaire. Results Significant suppression of circulating dihydrotestosterone levels with the administration of dutasteride or finasteride did not significantly affect bone mineral density or markers of bone metabolism. Similarly serum lipoproteins and hemoglobin were unaffected. Serum prostate specific antigen and self-assessed sexual function decreased slightly during treatment with both 5α-reductase inhibitors but returned to baseline during followup. Conclusions Profound suppression of circulating serum dihydrotestosterone induced by 5α-reductase inhibitors during 1 year does not adversely impact bone, serum lipoproteins or hemoglobin, and has a minimal, reversible effect on serum prostate specific antigen and sexual function in normal men. Circulating dihydrotestosterone does not appear to have a clinically significant role in modulating bone mass, hematopoiesis or lipid metabolism in normal men. PMID:18423697

    To analyze the clinical and prognostic value of neuron specific enolase (NSE) levels in serum of advanced lung cancer patients, we analyzed serum NSE level of 110 advanced lung cancer patients (case group), 100 benign lung disease patients (benign disease group), and 100 healthy persons (control group). Case group patients were divided by NSE level into ≥25 ng/mL (52 cases) and <25 ng/mL (58 cases) groups to analyze overall survival (OS) and progression-free survival (PFS). The results showed the serum NSE levels of case group patients were significantly higher than those of control or benign disease group patients (P<0.05). Serum NSE levels of small cell lung cancer patients were significantly higher than those of patients with other tumor pathologies (all P<0.05). Median OS significantly differed between patients with NSE levels ≥25 ng/mL (23.7 months) and <25 ng/mL (31.4 months) (P<0.05). Median PFS also significantly differed between patients with NSE levels ≥25 ng/mL (13.5 months) and <25 ng/mL (17.6 months) (χ 2=9.992; P<0.05). Tumor pathology (RR=4.136), patient performance status score (RR=2.903), and serum NSE level (RR=2.338) were factors influencing OS (P<0.05). Patient performance status score (RR=2.903), number of chemotherapy lines (RR=1.776), and serum NSE level (RR=2.075) were influencing factors in patients’ PFS (P<0.05). In brief, serum NSE level significantly correlates with advanced lung cancer patient prognosis and may be useful as an auxiliary index to predict prognosis. PMID:26309614

    Hyper- and hypothyroidism have significant effects on the female reproductive system. However, little in the way of data is available on the relationship between ovarian paracrine control and thyroid function. This study was aimed at characterising the serum levels of inhibin B in relation to altered thyroid function. Serum inhibin B and FSH levels were measured in 91 women (51 regularly cycling and 40 postmenopausal). The mean serum concentration of inhibin B in euthyroid cycling women (0.025 +/- 0.018 microg/l) was similar to that observed in hyper- and hypothyroid patients (0.022 +/- 0.015 and 0.018 +/- 0.014 microg/l, respectively, p=ns). Inhibin B levels were obviously reduced (-72%) in euthyroid postmenopausal women. In contrast, in hyper- and hypothyroid postmenopausal women, inhibin B levels remained substantially at the premenopausal level. So far, serum inhibin B appeared to be significantly increased in both hyperthyroid patients (0.025 +/- 0.014 microg/l; p<0.0001) and in hypothyroid patients (0.016 +/- 0.006 microg/l; p=0.0006). Altered thyroid function did not affect FSH levels at fertile age. However, a significant decrease of FSH levels was observed in hyper- and hypothyroid (-52% and -43%, respectively) postmenopausal women. Nevertheless, these FSH levels remained in the postmenopausal range. These results indicate that an altered thyroid function affects serum inhibin B levels in postmenopausal women. PMID:12953168

    Background. In an attempt to correlate biomarkers with disease, serum-based biomarkers often are compared between individuals with osteoarthritis (OA) and control subjects. However, variable results have been reported. Some studies have suggested an association between certain adipokines and insulin and OA. We know that there are racial differences in OA prevalence and incidence, and from general population-based studies, those of Asian race consistently demonstrate a unique adipokine/insulin serum concentration profile as compared to Caucasians. Whether similar racial differences exist within OA samples is unknown and may have implications for selecting appropriate controls in comparative studies. Methods. Serum levels of adipokines, leptin, and adiponectin, along with insulin, were determined by ELISA in patients scheduled for total hip or knee replacement surgery for OA. Fifteen Asian patients were matched 1 : 1 on age (±2 years), gender, body mass index (±1.5 kg/m2), and surgical joint with Caucasian patients. Differences in serum concentrations were tested using paired t-tests. Results. Serum leptin and insulin levels were significantly higher in Asians compared to Caucasians (p < 0.05). While serum adiponectin levels were lower among Asians, the difference did not reach statistical significance (p = 0.12). Conclusion. Findings from this work suggest that when studying serum biomarker concentrations in OA versus controls, race may be an important factor to consider. Our findings warrant confirmation in larger studies.

    We studied the serum estradiol and estrone levels in 146 peri and postmenopausal women, and in 38 women who had complained of various climacteric disturbance symptoms during daily hormone replacement therapy (HRT) with conjugated equine estrogen (CEE) 0.625 mg and medroxyprogesterone acetate (MPA) 2.5 mg. Serum estradiol and estrone were measured before treatment, and at 6 months, and after one year of the HRT therapy by HPLC-radioimmunoassay. In 146 peri and postmenopausal women, the serum level of estradiol was from 3 to 6pg/ml. The serum level of estradiol in 38 women after HRT significantly increased (p < 0.01) from 3.34 to 23.6 pg/ml at 6 months, and 21.5 pg/ml at 12 months. The serum level of estrone significantly increased (p < 0.01) from 26.6pg/ml to 156.7pg/ml at 6 months, and 137.2pg/ml at 12 month. These results are very useful for deciding on the doses of hormones and the expected serum estradiol level in HRT for Japanese women. PMID:7636337

    Trace elements play a critical role in the pathogenesis of autism spectrum disorders (ASD). The aim of this study was to investigate the serum levels of zinc (Zn) and copper (Cu) in Chinese children with ASD. Sixty patients (48 males, 12 females) diagnosed with ASD and 60 healthy sex-matched and age-matched control participants were assessed for serum Zn and Cu content at admission. The severity of ASD was also evaluated using the Childhood Autism Rating Scale (CARS) score. The results indicated that the mean serum Zn levels and Zn/Cu ratio were significantly lower in children with ASD compared with normal cases (P<0.001, respectively), whereas serum Cu levels were significantly higher (P<0.001). There was a significant negative association between Zn/Cu and CARS scores (r=-0.345, P=0.007). On the basis of the receiver operating characteristic curve, the optimal cut-off value of serum levels of Zn/Cu as an indicator for an auxiliary diagnosis of autism was projected to be 0.665, which yielded a sensitivity of 90.0% and a specificity of 91.7%; the area under the curve was 0.968 (95% confidence interval, 0.943-0.993). In conclusion, these results suggested an association between serum levels of Zn and Cu and ASD among Chinese patients, and the Zn/Cu ratio could be considered a biomarker of ASD. PMID:25162784

    Background/Aims The relationships between serum procalcitonin, inflammatory bowel disease (IBD) and intestinal Behçet’s disease (BD) have not been completely determined. We aimed to evaluate the usefulness of measuring serum procalcitonin levels to assess disease activity and infection stage in patients with IBD and intestinal BD. Methods We retrospectively analyzed clinical data from 129 patients with IBD and intestinal BD for whom serum procalcitonin and C-reactive protein (CRP) levels were measured between January 2006 and February 2013. Results The median serum procalcitonin levels in the IBD and intestinal BD with septic shock or sepsis (n=8), with localized infection (n=76), and without infection (n=45) were 3.46 ng/mL (range, 0.17 to 63.66 ng/mL), 0.22 ng/mL (range, 0.05 to 140.18 ng/mL), and 0.07 ng/mL (range, 0.00 to 31.50 ng/mL), respectively (p=0.001). The serum CRP levels in the IBD and intestinal BD patients did not differ according to the infection stage. Variations in serum procalcitonin levels were not observed in the IBD and intestinal BD patients with different disease activities. Conclusions Serum procalcitonin levels may not be affected by IBD and intestinal BD activity itself, although they may be affected by concomitant infection. Serum procalcitonin measurements could be more useful than CRP in determining the infection stage that reflects the severity of infection in IBD and intestinal BD patients. PMID:26780089

    AIM: To determine whether serum vascular endothelial growth factor (VEGF) levels correlates with the severity of liver cirrhosis and whether portal hypertension impacts on the expression of serum VEGF protein. METHODS: Fifty-three patients (mean age 56 ± 2 years) with HCV (n = 26), HBV (n = 13), and cryptogenic liver cirrhosis (n = 14) (Child-Pugh-s class A: 24, B: 19 and C: 12) and normal renal function constitute the patient population, who were all diagnosed by clinical, histological and radiological findings. Six healthy people and six patients with acute hepatitis served as controls. Severity of liver disease was evaluated by the CP score. Serum levels of IGF-1 and VEGF were measured by radioimmunoassay and ELISA, respectively. Portal hypertension was assessed using pulsed Doppler ultrasound. RESULTS: The mean serum VEGF levels in all cirrhotic patients (73 ± 58) were significantly lower than those of healthy controls (360 ± 217, P < 0.01) and acute hepatitis (1123 ± 1261, P < 0.01) respectively. No significant difference in median serum VEGF levels were noted among the different Child-Pugh-s classes (class A: median, 49.4 ng/L, range, 21-260 ng/L, Class B: median 59.9 ng/L; range 21-92, and Class C: median 69; range 20-247 ng/L). A significant correlation was noted between serum VEGF and two accurate parameters of portal hypertension: portal blood flow velocity (r = 06) and spleen size (r = 0.55). No correlation was found between VEGF serum levels and serum albumin, IGF-1, platelets count and aminotrasnferases (r = 0.2, r = 0.1, r = 0.2 and r = 0.2, respectively). CONCLUSION: Circulating VEGF level in patients with liver cirrhosis could not serve as an indicator of the progression of chronic liver disease but rather, they may reflect increased portal hypertension or decreased hepatic regenerative activity or the combination of both.

    Background Gastric cancer (GC) is the most common gastrointestinal cancer in Iran. Helicobacter pylori (H. pylori) accounts as one of the main risk factors for gastric non-cardia cancer (GNCC). It is suggested that high serum selenium level may have a protective role in GNCC. In this cross-sectional study, we determined the serum Se level and the status of H. pylori infection in two populations with GC and functional dyspepsia (FD). Methods The enrolled patients were 85 (27 women, 58 men) with recent pathologically proven GNCC (adenocarcinoma) and 85 (34 women, 51 men) FD patients. Serum Se was measured by atomic absorption spectrophotometry. H. pylori IgG antibody was detected by quantitative enzyme immunoassay. Results The mean age in the GNCC and FD patients were 62.85±14.6 and 58.9±14.7 years, respectively (P=0.08). The serum selenium levels were 111.6±27.7 and 129.9±32.1 μg/L (mean±SD) in GNCC and FD patients, respectively (P<0.001). The frequency of H. pylori infection was 49.4% (n=42) and 68.2% (n=58) in GNCC and FD patients (P=0.013). The crude and adjusted odds ratio (OR) between GNCC and the linear effect of serum selenium level were 0.98 and 0.982, respectively (P=0.002). This means that each unit increase in serum selenium level decreases the odds of cancer by 2%. Conclusion Serum selenium level was significantly lower in GNCC cases. It suggests that lower serum selenium might have some association with the risk of GNCC. H. pylori infection does not play a significant impact on this association. PMID:25999620

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

    Carcinoembryonic antigen (CEA) affects tumorigenesis by enhancing tumor cell survival and by inducing tumor angiogenesis. This study aimed to evaluate baseline CEA serum levels to predict bevacizumab-based therapy effect and survival in patients with metastatic colorectal cancer (mCRC). Two hundred and ninety eight mCRC patients receiving chemotherapy plus either bevacizumab or cetuximab were analyzed in a retrospective study. Disease control (DC), progression-free survival (PFS), and overall survival were assessed and related to pretreatment CEA serum levels. Patients with baseline CEA serum levels below the statistical median of 26.8 ng/mL (group I) were compared with patients with higher CEA levels (group II). The cetuximab-based treatment cohort was analyzed for specificity assessment of CEA to predict the anti-vascular endothelial growth factor effect in mCRC. Baseline CEA serum levels inversely correlated with therapeutic response in patients receiving bevacizumab-based treatment (disease control rate, 84% vs 60%), inversely correlated with median PFS leading to a median PFS benefit of 2.1 months for patients in group I when compared with group II, as well as inversely correlated with median overall survival (37.5 months vs 21.4 months). In an independent cohort of 129 patients treated with cetuximab-based therapy, no association of therapeutic response or PFS with CEA serum levels was found. As expected, baseline CEA levels were prognostic for mCRC. These data give first evidence that baseline serum CEA levels might constitute an important predictor for the efficacy of first-line bevacizumab-based therapy in patients with mCRC. Previously, we found that CEA induces angiogenesis independent of VEGF. The data presented here now give first evidence that baseline serum CEA levels in patients might constitute an important predictor for the efficacy of first-line bevacizumab-based therapy for metastatic colorectal cancer.

    This study describes the effects of fluoride exposure on the protein profile, glycoprotein pattern, and total sialic acid concentration of serum in rabbits. For this aim; 20 healthy New Zealand rabbits were used. The rabbits were divided into two equal groups each with ten animals according to their weighing: control group and experimental group. The rabbits in control group were given drinking tap water containing 0.29 mg/l sodium fluoride and experimental group received the same tap water to which was added 40 mg/l sodium fluoride for 70 days. Blood samples were taken from each rabbit on day 70. Serum fluoride concentrations were measured by a fluoride-specific ion electrode in serum. The fluoride levels in the serum were found as 18.4 (+/-1.58) microg/L in control and 301.3 (+/-52.18) microg/L in fluoride exposed rabbits. The sialic acid levels were found as 69.2 (+/-0.32) mg/dL in control and 43.4 (+/-0.13) mg/dL in fluoride exposed group. The electrophoretic patterns of serum proteins, glycoproteins, and total sialic acid concentration were determined. Fifteen different protein fractions with molecular weights ranging from 22 to 249 kDa were displayed in the serum protein electrophoretic gel of both groups. The raw concentrations of the protein fractions decreased in fluoride exposed rabbits as compared with the control rabbits. The serum glycoprotein pattern revealed seven major protein bands from 47 to 167 kDa in experimental and control groups. The slight decrease of raw concentration of the protein bands in glycoprotein pattern of serum was observed in fluoride toxication comparing to control. The results suggest that serum TSA determination and serum protein electrophoresis can be used to evaluate prognosis of fluoride exposure as a supplementary laboratory test in combination with clinical and other laboratory findings of fluorosis.

    Abstract Adipocyte fatty acid-binding protein (AFABP) has been shown to be a biomarker of body weight change and atherosclerosis. Changes in thyroid function are associated with changes in body weight and risks of cardiovascular diseases. The association between AFABP and thyroid function status has been seldom evaluated. The aim of this study was to compare the serum AFABP concentrations in hyperthyroid patients and those in euthyroid individuals, and to evaluate the associations between serum AFABP and free thyroxine (fT4) levels. For this study, 30 hyperthyroid patients and 30 euthyroid individuals at a referral medical center were recruited. The patients with hyperthyroidism were treated with antithyroid regimens as clinically indicated. No medication was given to the euthyroid individuals. The body weight, body mass index, thyroid function, serum levels of AFABP, and biochemical data of both groups at baseline and at the 6th month were compared. Associations between AFABP and fT4 levels were also analyzed. At the baseline, the hyperthyroid patients had significantly higher serum AFABP levels than the euthyroid individuals (median [Q1, Q3]: 22.8 [19.4, 30.6] ng/mL vs 18.6 [15.3, 23.2] ng/mL; P = 0.038). With the antithyroid regimens, the AFABP serum levels of the hyperthyroid patients decreased to 16.6 (15.0, 23.9) ng/mL at the 6th month. No difference in the AFABP level was found between the hyperthyroid and the euthyroid groups at the 6th month. At baseline, sex (female vs male, ß = 7.65, P = 0.022) and fT4 level (ß = 2.51, P = 0.018) were significantly associated with AFABP levels in the univariate regression analysis. At the 6th month, sex and fT4 level (ß = 8.09, P < 0.001 and ß = 3.61, P = 0.005, respectively) were also significantly associated with AFABP levels. The associations between sex and fT4 level with AFABP levels remained significant in the stepwise multivariate regression analysis, both at baseline and at

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

    Patients with ankylosing spondylitis (AS) have an increased risk of bone loss and vertebral fractures. In this study, we explored the hypothesis that the excess bone loss and vertebral fractures might be related with the activity of the Wingless signaling pathway, and in particular with the serum levels of its circulating inhibitors, Sclerostin and Dickkopf-1 (DKK1). We recruited 71 patients diagnosed with AS. Lateral radiographs of the total spine were analyzed to detect the presence of vertebral fractures, and bone mineral density (BMD) was assessed in all patients using dual X-ray absorptiometry at lumbar spine and proximal femoral site. Blood samples were obtained and levels of C-reactive protein (CRP), DKK1, and Sclerostin were measured. Blood samples from 71 healthy sex- and age-matched volunteers were collected to be used as controls. Vertebral fractures were detected more commonly among men than in women (29 vs 8 %, respectively). DKK1, but not Sclerostin serum levels, were inversely correlated to lumbar spine Z-score BMD. Patients with one or more prevalent vertebral fractures had significantly higher DKK1 levels, without significant difference in Sclerostin serum levels. A significant positive correlation was found between DKK1 serum levels and CRP (r = 0.240, p = 0.043). The association we found between serum DKK1 levels and BMD values and vertebral fracture prevalence suggests that DKK1 might contribute to the severity of osteoporosis in AS. PMID:26645432

    Several lines of evidence point to a possible relationship between vitamin D and cardiovascular disease. Animal experiments and observational studies in humans suggest vitamin D to be arteriotoxic and an association of high intake of vitamin D with increased incidence of ischemic heart disease (IHD). The major source of vitamin D in adults is vitamin D synthesized in the skin through exposure to the sun. In tropical environment there is a possibility of high level of solar exposure and enhanced serum levels of vitamin D in the population. We explored the relation between serum level of 25-hydroxyvitamin D3 and IHD in a case-control study involving 143 patients with either angiographic evidence of coronary artery disease or patients with acute myocardial infarction and 70 controls, all men in the age group of 45-65 years. Fasting blood samples were collected, serum separated and serum levels of 25-hydroxyvitamin D3 was measured by protein binding radioligand assay. Serum levels of cholesterol, triglyceride, calcium, magnesium and inorganic phosphate were also determined. Prevalences of diabetes, hypertension and smoking history were noted. Statistical comparisons of variables between cases and controls were done using chi2-tests. Multivariate logistic regression analysis was done to examine the association of IHD with serum levels of 25-hydroxyvitamin D3 controlling for selected variables. Serum levels of 25-hydroxyvitamin D3, calcium, inorganic phosphate, total cholesterol, low density lipoprotein and triglycerides were elevated in a higher proportion of patients, compared to controls. Serum levels of 25-OH-D3 above 222.5 nmol/l (89 ng/ml) was observed in 59.4% of cases compared to 22.1% in controls (p < 0.001; unadjusted odds ratio (OR): 5.17; 95% confidence interval (CI): 2.62-10.21). When controlled for age and selected variables using the multivariate logistic regression, the adjusted OR relating elevated serum 25-hydroxyvitamin D3 levels (> or = 222.5 nmol

    Insulin-like growth factor-1 (IGF-1) and its essential binding protein-3 (IGFBP-3) exhibit significant roles in cellular proliferation, differentiation and apoptosis in numerous malignancies, including lung cancer. The aim of the present study was to determine the clinical roles of the serum IGF-1 and IGFBP-3 levels in lung cancer patients. A total of 80 patients with lung cancer were enrolled in the study. Serum IGF-1 and IGFBP-3 concentrations were determined by ELISA methods. The median age of patients was 58.5 years old, with a range of 36–80 years. The majority of the patients had non-small cell lung cancer (NSCLC) (85%) and metastatic disease (56%). No significant differences were observed in serum IGF-1 levels between lung cancer patients and healthy subjects (P=0.403). However, baseline serum IGFBP-3 levels of the lung cancer patients were significantly lower compared to the control group (P<0.001). The male patients had elevated serum IGF-1 concentrations compared to females (P=0.025). Furthermore, patients with NSCLC histology and metastatic stage in NSCLC had elevated serum IGF-1 (P=0.022 and P=0.039, respectively) and IGFBP-3 (P=0.005 and P=0.043, respectively) levels compared with those with SCLC histology and non-metastatic stage in NSCLC. However, none of the other clinical variables, including age of patient, tumor histology and chemotherapy responsiveness, were observed as correlated with serum assays of IGF-1 and IGFBP-3 (P>0.05). There was a significant association found between IGF-1 and IGFBP-3 serum levels in lung cancer patients (P<0.001). Neither serum IGF-1 nor IGFBP-3 concentrations were associated with outcome (P=0.552 and P=0.471, respectively). In conclusion, serum concentrations of IGFBP-3 may have a diagnostic predictor in patients with lung cancer compared to serum IGF-1 concentrations. However, predictive and prognostic values of the two serum assays were not observed. PMID:27123256

    The purpose of this study was to explore the effects of high fluoride and high fat on triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total antioxidant capacity (T-AOC), lipid peroxide (LPO) and malondialdehyde (MDA) in rabbits. A factorial experimental design was used, with two factors (fluoride and fat) and three levels. Seventy-two male rabbits were randomly assigned into nine groups according to initial weight and serum lipid levels. The rabbits were fed with basic feed, moderate fat feed or high fat feed and drank tap water, fluoridated water at levels of 50 and 100mgfluorion/L freely. Biological materials were collected after 5 months, and serum lipid, T-AOC, LPO, and MDA levels were then measured. Using these data, the separate and interactive effects of high fluoride and high fat were analyzed. High fluoride and high fat both increased serum levels of TC, HDL-C and LDL-C significantly (P<0.05), and there was also a synergistic effect between high fluoride and high fat (P<0.05). High fluoride and high fat had different effects on TG levels: high fat significantly increased TG levels (P<0.01) whereas high fluoride had nothing to do with TG levels (P>0.05). High fat significantly elevated LPO and MDA levels and lowered T-AOC levels in serum (P<0.05). Similarly, high fluoride significantly increased LPO and MDA levels in serum (P<0.05). However, there was no interactive effect between high fat and high fluoride on these indexes. In summary, high fluoride and high fat increased serum TC and LDL-C levels individually and synergistically, and this would cause and aggravate hypercholesterolemia in rabbits. At the same time, high fluoride and high fat both made the accumulation of product of oxidative stress in experimental animals. PMID:25461561

    Objective C-reactive protein (CRP) has previously been shown to serve as a prognostic parameter in women with gynecologic malignancies. Due to the lack of valid prognostic markers for uterine leiomyosarcoma (ULMS) this study set out to investigate the value of pre-treatment CRP serum levels as prognostic parameter. Methods Data of women with ULMS were extracted from databases of three Austrian centres for gynaecologic oncology. Pre-treatment CRP serum levels were measured and correlated with clinico-pathological parameters. Univariate and multivariable survival analyses were performed. Results In total, 53 patients with ULMS were included into the analysis. Mean (SD) CRP serum level was 3.46 mg/dL (3.96). Solely, an association between pre-treatment CRP serum levels and tumor size (p = 0.04) but no other clinic-pathologic parameter such as tumor stage (p = 0.16), or histological grade (p = 0.07), was observed. Univariate and multivariable survival analyses revealed that CRP serum levels (HR 2.7 [1.1–7.2], p = 0.037) and tumor stage (HR 6.1 [1.9–19.5], p = 0.002) were the only independent prognostic factors for overall survival (OS) in patients with ULMS. Patients with high pre-treatment CRP serum levels showed impaired OS compared to women with low levels (5-year-OS rates: 22.6% and 52.3%, p = 0.007). Conclusion High pre-treatment CRP serum levels were independently associated with impaired prognosis in women with ULMS and might serve as a prognostic parameter in these patients. PMID:26248232

    ABSTRACT This study was aimed to evaluate the relationship between serum interleukin-23 (IL-23) levels and ankylosing spondylitis (AS).Twenty male patients diagnosed with ankylosing spondylitis according to the 1984 modified New York criteria for AS and twenty male healthy controls were included in this study.The demographic characteristics, clinical and laboratory findings of the patients were recorded. Serum IL-23 levels, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured in both the AS and control groups. The Bath ankylosing spondylitis disease activity ındex (BASDAI), the Bath ankylosing spondylitis functional index (BASFI), and the Bath ankylosing spondylitis metrology index (BASMI) were evaluated as disease activity parameters. The AS patients were divided into two subgroups as active and inactive in respect of CRP, ESR levels and BASDAI scores. The mean serum IL-23 levels of the AS and control groups were 334.45±176.54 pg/ml and 166.49±177.50 pg/ml respectively, and there was a significant difference between the groups. Correlation analysis of serum IL-23 levels with clinical and laboratory parameters showed that there were positive correlations between serum IL-23 levels and the BASDAI, BASFI scores in total, active and inactive patients and the BASMI scores in total and inactive patients and negative correlations between serum IL-23 levels and ESR in inactive patients. It was shown that altered serum IL-23 levels were related to AS disease activity. Further studies in large patient series are necessary to investigate the role of IL-23 protein in etiopathogenesis of AS. PMID:26663940

    Circulating erythropoietin (EPO) is mainly produced in the kidneys, depending on blood oxygen level. The present study investigated the postmortem serum EPO levels with regard to the cause of death and survival time. Serial medicolegal autopsy cases of postmortem time within 48 h (n = 536) were examined. Serum EPO levels were within the clinical reference range in most cases. Uremic patients with medical administration of an EPO agent (n = 11) showed a markedly high level (140-4,850 mU/ml; median, 1,798 mU/ml). Otherwise, an elevation in serum EPO level (>30 mU/ml) was mainly seen in protracted deaths due to blunt injury and fire fatality, depending on the survival time (r = 0.69, p < 0.0001, and r = 0.45, p < 0.0001, respectively), and in subacute deaths from gastrointestinal bleeding and infectious diseases. However, mildly to moderately elevated serum EPO levels were sporadically found in acute deaths due to mechanical asphyxiation, fire fatality, and acute ischemic heart disease, and in fatal hypothermia cases, especially for elderly subjects. Protracted deaths due to mechanical asphyxiation and ischemic heart disease did not show any survival time-dependent increase in serum EPO level (p > 0.05). EPO was immunohistochemically detected in the tubular epithelia and interstitial cells, showing no evident difference among the causes of death, independent of survival time or serum level. These findings suggest that serum EPO can be used as a marker for investigating anemia and/or hypoxia as a consequence of fatal insult in subacute or prolonged deaths, or a predisposition to traumatic deaths or fatal heart attacks in acute deaths.

    An elevated serum phosphorus (P) has been anecdotally described in premature infants receiving human milk fortified with donor human milk-derived fortifier (HMDF). No studies have prospectively investigated serum P in premature infants receiving this fortification strategy. In this single center prospective observational cohort study, extremely premature infants ≤1250 grams (g) birth weight (BW) were fed an exclusive human milk-based diet receiving HMDF and serum P levels were obtained. We evaluated 93 infants with a mean gestational age of 27.5 ± 2.0 weeks (Mean ± SD) and BW of 904 ± 178 g. Seventeen infants (18.3%) had at least one high serum P level with a mean serum P of 9.2 ± 1.1 mg/dL occurring at 19 ± 11 days of life. For all infants, the highest serum P was inversely correlated to the day of life of the infant (p < 0.001, R2 = 0.175) and positively correlated with energy density of HMDF (p = 0.035). Serum P was not significantly related to gender, BW, gestational age, or days to full feeds. We conclude that the incidence of hyperphosphatemia was mild and transient in this population. The risk decreased with infant age and was unrelated to gender, BW, or ethnicity. PMID:25912036

    Background: Detection of cancer at the early stage is of utmost importance to decrease the morbidity and mortality of the disease. Apart from the conventional biopsy, minimally invasive methods like serum evaluation are used for screening large populations. Thus, this study aimed to estimate serum levels of sialic acid and fucose and their ratio in oral cancer patients and in healthy control group to evaluate their role in diagnosis. Materials and Methods: Serum samples were collected from 52 healthy controls (group I) and 52 squamous cell carcinoma patients (group II). Estimation of serum levels of sialic acid and fucose and their ratio was performed. This was correlated histopathologically with the grades of carcinoma. Statistical analysis was done by using analysis of variance (ANOVA) test and unpaired “t” test. Results: Results showed that serum levels of sialic acid and fucose were significantly higher in oral cancer patients compared to normal healthy controls (P < 0.001). The sialic acid to fucose ratio was significantly lower in cancer patients than in normal controls (P < 0.01). However, comparison with histological grading, habits, gender, and age group did not show any significant result. Conclusion: The mean serum sialic acid and fucose levels showed an increasing trend from controls to malignant group and their corresponding ratio showed decreasing trend from controls to malignant group. The ratio of sialic acid to fucose can be a useful diagnostic aid for oral cancer patients. PMID:26759796

    Cytochrome P450 inhibition through fruit supplement interactions often results in increased serum levels of calcineurin inhibitors, including tacrolimus. Cranberry extract is a supplement often used for the prevention of recurrent urinary tract infections (UTIs), which are common in renal allograft recipients. To our knowledge, a decrease in serum levels of tacrolimus as a result of cranberry extract interaction is unreported. A 40-year-old renal transplant patient taking cranberry extract capsules for her recurrent cystitis presented asymptomatically with low serum levels of tacrolimus. Dose increase had little effect on the level, and cessation of the cranberry extract returned levels to desired range. Cranberry extracts are an adjunctive therapy used in the management of recurrent UTIs. Tacrolimus, an immunosuppressive agent, is metabolized intestinally by isoenzymes of the P450 cytochrome. Cranberry extracts may alter this metabolism and lead to sub-therapeutic serum levels of tacrolimus. This interaction is heretofore unreported. Cranberry extracts should be carefully monitored in allograft recipients due to interactions with serum tacrolimus levels. PMID:27335715

    Soluble interleukin-2 receptor (sIL-2R) levels were quantitated in the serum and synovial fluid (SF) of patients with rheumatoid arthritis (RA) and degenerative joint disease (DJD). A sandwich immunoassay, employing two monoclonal antibodies against distinct epitopes on the IL-2R, was utilized for measurement. We found a striking elevation of sIL-2R in RA SF as compared with DJD SF (RA, 1319 +/- 135; DJD, 416 +/- 59; p less than 0.001). RA serum sIL-2R levels were also significantly elevated over DJD levels. There was no interaction between rheumatoid factor (RF) and sIL-2R. RA patients with elevated sIL-2R levels had significantly longer disease duration, higher c-reactive protein (CRP) levels in serum and SF, and higher RF levels in serum and SF. The groups were similar in regard to other laboratory variables. The presence of elevated levels of sIL-2R in RA serum and SF confirms the presence of a heightened immune reactivity and in vivo activation of lymphocytes in RA. PMID:2313471

    Survival among hemodialysis patients is disturbingly low, partly because vascular calcification (VC) and cardiovascular disease are highly prevalent. Elevated serum phosphorus (P) and calcium (Ca) levels play an essential role in the formation of VC events. The purpose of the current study was to reveal optical monitoring possibilities of serum P and Ca values during dialysis. Twenty-eight patients from Tallinn (Estonia) and Linköping (Sweden) were included in the study. The serum levels of Ca and P on the basis of optical information, i.e., absorbance and fluorescence of the spent dialysate (optical method) were assessed. Obtained levels were compared in means and SD. The mean serum level of Ca was 2.54 ± 0.21 and 2.53 ± 0.19 mmol/L; P levels varied between 1.08 ± 0.51 and 1.08 ± 0.48 mmol/L, measured in the laboratory and estimated by the optical method respectively. The levels achieved were not significantly different (p = 0.5). The Bland-Altman 95% limits of agreement between the two methods varied from −0.19 to 0.19 for Ca and from −0.37 to 0.37 in the case of P. In conclusion, optical monitoring of the spent dialysate for assessing the serum levels of Ca and P during dialysis seems to be feasible and could offer valuable and continuous information to medical staff.

    Hypotheses regarding an immune-cytokine basis of schizophrenia have been postulated with controversial findings and a lack of data related to many cytokines. The aim of this study was to assess serum levels of Interferon-γ (IFN-γ), Interleukin-4 (IL-4), Transforming Growth Factor-β (TGF-β), Interleukin-17 (IL-17) and B-cell Activating Factor (BAFF) in schizophrenic patients and to determine correlations between cytokine levels and clinical parameters. Serum cytokine levels were measured with ELISA techniques in 60 neuroleptic-free patients on acute phase of the disease (BPRS≥40) and 28 healthy controls matched for age and sex. Current symptoms were assessed with Brief Psychiatric Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), Scale for the Assessment of Positive Symptoms (SAPS) and Scale for the Assessment of Negative Symptoms (SANS). No significant difference was found between patients and controls regarding IFN-γ serum levels. IL-4 was not detected in both groups. Patients exhibited significantly higher IL-17 and lower BAFF serum levels. IL-17 and BAFF levels were negatively correlated in schizophrenic patients. SANS global score was negatively correlated with IL-17 and positively correlated with IFN-γ serum levels. These results argue against the involvement of Th1 or Th2 population cells in schizophrenia. IL-17 and BAFF could be valuable markers for schizophrenia. PMID:25453636

    Introduction: Ghrelin is a novel brain-gut peptide hormone consisted of 28 amino-acid. In the plasma, it exists in two major molecular forms, acylated and des-acyled ghrelin, filtered in glomeruli or secreted by nephrons. Primary biological effects of hormones are regulating appetite, foods intake and energy metabolism. We investigated the changing and relationships between serum and urine ghrelin levels in acute stroke patients to provide more information whether diagnostic parameter. Methods: Thirty acute stroke patients and thirty consecutive volunteers included in study prospectively. To analyze serum and urine ghrelin levels, at the time of diagnose, all of participant blood and fresh urine (1 ml serum, 2 ml urine respectively) samples were obtained. Serum ghrelin levels analyzed ELISA technique, and urine ghrelin levels studied by validation technique. To compare quantitative data student’s t test, and for qualitative data chi-square and Fisher’s Exact Chi-square test was used. P<0.05 was considered statistically significant. Results: Urine acyl ghrelin levels found statistically significant between patient and control groups (P=0.001), but there were no statistically significant differences between both groups (P>0.05) in serum acyl gherelin, des-acyl ghrelin and urine des-acyle ghrelin levels. Conclusions: The results indicate that urine acyl ghrelin levels may be considered as a diagnostic parameter in acute ischemic stroke patients. Further studies delineating the mechanism of these observed results are warranted. PMID:25785049

    BACKGROUND: Actinic prurigo is an idiopathic photodermatosis, the pathophysiology of which has been hypothesized to involve subtype IV type b (Th2) hypersensitive response, whereby IL4, IL5, and IL13 are secreted and mediate the production of B cells, IgE, and IgG4. OBJECTIVES: To examine the association of serum IgE levels and the clinical severity of injuries. METHODS: This case-control study comprised patients with a clinical and histopathological diagnosis of actinic prurigo, as well as clinically healthy subjects, from whom 3cc of peripheral blood was taken for immunoassay. Cases were classified by lesion severity as mild, moderate, and severe. Descriptive statistics were analyzed, and chi-square test was performed. RESULTS: We included 21 actinic prurigo patients and 21 subjects without disease; 11 patients with actinic prurigo had elevated serum IgE levels, and 10 had low serum levels. Six actinic prurigo (AP) patients with elevated serum levels of IgE had moderate injuries, 4 had severe injuries, and 1 had minor injuries. Eight out of 10 patients with normal IgE levels presented with minor injuries in the clinical evaluation. The 21 controls did not have increased serum IgE levels. CONCLUSIONS: Elevated IgE levels are associated with moderate to severe clinical lesions, suggesting that actinic prurigo entails a type IV subtype b hypersensitivity response in which Th2 cells predominate.

    Coronary artery disease (CAD) has become the most common cause of mortality in the entire world. Homocysteine is implicated as an early atherosclerotic promoter. We studied the relationship between levels of serum homocysteine with severity of coronary artery disease. Total of 70 subjects who scheduled for coronary angiogram consented to participate in this study. In all the patients Gensini scoring system was used to assess the severity of CAD. Venous samples were taken from the patients in fasting state before angiography. Homocysteine levels in patients were measured by enzyme linked immunosorbant method and were compared with respective Genseni scores of participants. Fasting serum homocysteine levels in CAD patients were significantly higher than patients without coronary artery disease (p < 0.001). Also Homocyseine levels correlated significantly with increasing severity of CAD (p < 0.001). Serum homocysteine levels correlated well with the severity of CAD. PMID:24966483

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

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

    The present study aimed to investigate the serum levels and clinical relevance of claudin (CLDN) 1 and CLDN7 in patients with colorectal cancer (CRC). A total of 140 patients with a pathologically confirmed diagnosis of CRC were enrolled in this study. The serum levels of CLDN1 and CLDN7 were determined using the solid-phase sandwich ELISA method. A total of 40 healthy age- and gender-matched controls were included in the analysis. The median age of the patients was 60 years (range, 24–84 years). The localization of the tumor in the majority of the patients was the colon (n=81, 58%). Of the 55 metastatic patients who received palliative chemotheraphy, 31% were chemotherapy-responsive. The baseline median serum CLDN1 and CLDN7 levels were significantly lower in non-metastatic and metastatic patients compared with those in healthy controls (CLND1, P=0.008 and 0.002; and CLND7, P=0.002 and 0.002, respectively). Moreover, known clinical variables, including poor performance status and high carcinoembryonic antigen (CEA) levels were found to be associated with lower serum CLDN1 concentrations for all patients (P=0.03 and P=0.03, respectively). High T stage and high CEA levels were found to be correlated with lower serum CLDN7 concentrations for all patients (P=0.04 and 0.03, respectively). A correlation was identified between CLDN1 and CLDN7 levels in non-metastatic and metastatic CRC patients (both P-values <0.001). Our study results did not reveal any statistical significance for serum CLDN1 or CLND7 concentrations regarding progression-free and overall survival rate. Therefore, reduced serum levels of CLDN1 and CLND7 may be useful markers in the differential diagnosis of CRC. PMID:26807230

    Background Serum haptoglobin (Hp) is a reliable marker for hemolysis regardless the inflammatory state. Objective We investigated the possible relation between Hp depletion and hemolysis severity, hepatitis C virus (HCV) infection and iron load in β-thalassemia children. Methods Twenty two β-thalassemia major (TM),20 β-thalassemia intermedia (TI) children with 20 age and sex matched healthy controls were involved. Pre-transfusion hemoglobin level was considered. Serum ferritin, Hp and transferrin receptor levels (sTfR) (by ELISA ), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (by colorimetric method) were assayed. Markers of hepatitis C virus (HCV) were done by PCR. Results The mean Hp levels among the studied groups were as follows; 8.02 ± 0.93 (mg/dl), 8.6 ±0.72 (mg/dl) and 122 ± 18.5(mg/dl) for TM, TI and the controls respectively. Both patient groups had significantly lower Hp level compared to the controls (P<0.0001) with significant lower level in TM compared to TI children ( P= 0.034). Significant inverse correlations were found between serum Hp and sTfR levels ( reflecting the erythropoietic activity) in thalassemia children combined and in each group (TM and TI) as well as among HCV infected children. STfR was the only significant independent predictor for serum Hp level (t= −5.585, P<0.0001). Among HCV infected patients, no significant correlation was found between serum Hp and serum transaminases. Conclusion Serum Hp depletion in thalassemia had significant relation to disease severity and correlated well with their erythropoietic activity, as assessed by the measurement of sTfR without significant relation to HCV infection. Extensive multicenter studies are recommended. PMID:25745546

    The association between serum zinc level and preeclampsia (PE) remains controversial. A systematic literature search was performed in PubMed, Web of Science and Embase for relevant available articles. The articles were limited to those in English from January 1990 to April 2015. Observational studies evaluating the association between serum zinc level and PE were included. The I2 was used to assess heterogeneity and the random effect model (REM) was adopted as the pooling method. The pooled standard mean difference (SMD) with 95% confidence interval (CI) was used to estimate the association between serum zinc level and PE. Seventeen observational studies were included. Compared with healthy pregnancy controls, PE patients have lower serum zinc level in 14 studies about total PE (SMD (95% CI): −0.587 (−0.963, −0.212), Z = 3.06, p for Z = 0.002; I2 = 88.4%, p for I2 < 0.0001). In subgroup analysis, a lower serum zinc level in PE patients compared with healthy pregnancy controls was observed in studies conducted in Asia, studies with zinc level measured in serum, and studies involving fasting participants. The SMD did not differ significantly between studies with healthy pregnancy controls matched by individual age (yes or no), and by individual gestational age (yes or no), respectively. Results from this meta-analysis indicate that serum zinc level in PE patients is significantly lower than that in healthy pregnancy controls. A moderate amount of zinc supplementation during pregnancy is advocated to reduce the incidence of PE. PMID:26389947

    AIM To investigate the serum levels of vascular endothelial growth factor receptor-2 (VEGFR-2) and adropin in age-related macular degeneration (AMD) patients. METHODS Ninety-eight AMD patients were included in the study. Seventy-eight age- and sex-matched healthy volunteers were recruited as the control group. Fundus florescein angiography and optical coherence tomography were performed to assess the posterior segment details. Serum VEGFR-2 and adropin levels were measured using enzyme-linked immunosorbent assays and compared between the study groups. RESULTS AMD group had significantly increased foveal retinal thickness, serum LDL and HDL levels and significantly decreased subfoveal choroidal thickness (P =0.01, 0.047, 0.025 and <0.001, respectively). Serum VEGFR-2 level revealed a significant decrease in AMD patients compared to controls (26.48±6.44 vs 30.42±7.92 ng/mL, P<0.001). There was an insignificant increase in serum adropin level in AMD patients (6.17±3.19 vs 5.79±2.71 ng/mL, P=0.4). Serum level of VEGFR-2 in AMD patients had a significant negative correlation with foveal retinal thickness (r=-0.226, P=0.025) and a significant positive correlation with subfoveal choroidal thickness (r=0.2, P=0.048). CONCLUSION The current study demonstrated that the decreased serum VEGFR-2 level may be considered in the development of AMD. Adropin does not seem to play a role in the pathogenesis of AMD.

    Introduction Chromium is an essential micronutrient which is required for the normal functioning of insulin and regulation of blood sugar levels. It acts as a vital antioxidant for maintaining insulin homeostasis. In diabetes mellitus, the free radical production is increased and levels of antioxidants like chromium, vanadium, selenium and manganese are reduced. There have been previous studies to suggest that low serum levels of chromium are associated with poorer glycaemic control. Aim To study the level of serum chromium in newly diagnosed patients with type 2 diabetes mellitus and its association with glycaemic control. Materials and Methods Serum chromium concentration was determined by using inductively coupled Plasma – Optical Emission Spectophotometry in 42 newly diagnosed type 2 diabetes mellitus patients without any pre-existing complications. They were divided into 2 groups – well controlled (HbA1c ≤7.0%) and uncontrolled groups (HbA1c >7.0%). Results Mean serum chromium concentration measured in uncontrolled type 2 diabetic patients was significantly lower (0.065 ± 0.03 mcg/L vs 0.103 ± 0.04 mcg/L, p< 0.05). There was a statistically significant inverse linear correlation of the HbA1c values and the serum chromium concentration (r= -0.6514, p < 0.0001). There was also a decrease in chromium levels across both the groups with advancing age and the decrease being significant beyond 40 years of age (p<0.05). Conclusion The results of our study describes the relationship between serum chromium levels and control of type 2 diabetes mellitus. Significant reduction in chromium levels are probable indicators of metabolic response to oxidative stress in patients with type 2 diabetes mellitus. Further large scale studies relating serum chromium and type 2 diabetes mellitus may help to understand more about the exact relationship. PMID:26676175

    Aim: To evaluate the relationship between epidermal growth factor receptor (EGFR) mutations and serum carcinoembryonic antigen (CEA) levels in Chinese nonsmokers with pulmonary adenocarcinoma. Methods: We sequenced exons 18–21 of the EGFR gene in 98 cases. The patients were divided into two groups based on their pre-treatment serum CEA levels (below or above 5 ng/mL) for analyzing the correlations with EGFR mutations. Results: Sixty-seven cases harbored EGFR mutations. The rates of EGFR mutations and exon 19 mutations in the high-CEA group (78.2% and 49.1%, respectively) were significantly higher those in the low-CEA group (55.8% and 20.9%, respectively). Serum CEA levels were found to be the only independent predictor of EGFR mutation (OR 2.837; 95% CI: 1.178–6.829) and exon 19 mutation (OR 3.618; 95% CI: 1.319–9.918). Furthermore, a higher serum CEA level was associated with a higher EGFR mutation rate and a higher exon 19 mutation rate: patients with serum CEA levels <5 ng/mL, ≥5 and <20 ng/mL, ≥20 ng/mL showed the EGFR mutation rate of 55.8%, 74.1%, 82.1%, respectively, and the exon 19 mutation rate of 20.9%, 40.7%, 57.1%, respectively. Patients with EGFR mutations displayed a significantly higher incidence of abnormal serum CEA levels (>5 ng/mL) than patients without EGFR mutations (64.2% vs 38.7%). Conclusion: Elevated serum CEA levels predict the presence of EGFR gene mutations in Chinese nonsmokers with pulmonary adenocarcinoma. PMID:24487967

    Abstract Serum gamma-glutamyltransferase (GGT) level has been considered marker of oxidative stress as well as liver function. Serum GGT level has been reported to be associated with the mortality in hemodialysis patients. However, it is not well established whether serum GGT level is associated with all-cause mortality in peritoneal dialysis (PD) patients. The aim of this study was to determine the association between serum GGT levels and all-cause mortality in PD patients. PD patients were included from the Clinical Research Center registry for end-stage renal disease cohort, a multicenter prospective observational cohort study in Korea. Patients were categorized into 3 groups by tertile of serum GGT levels as follows: tertile 1, GGT < 16 IU/L; tertile 2, GGT = 16 to 27 IU/L; and tertile 3, GGT > 27 IU/L. Primary outcome was all-cause mortality. A total of 820 PD patients were included. The median follow-up period was 34 months. Kaplan–Meier analysis showed that the all-cause mortality rate was significantly different according to tertiles of GGT (P = 0.001, log-rank). The multivariate Cox regression analysis showed that higher tertiles significantly associated with higher risk for all-cause mortality (tertile 2: hazard ratio [HR] 2.08, 95% confidence interval [CI], 1.17–3.72, P = 0.013; tertile 3: HR 1.83, 95% CI, 1.04–3.22, P = 0.035) in using tertile 1 as the reference group after adjusting for clinical variables. Our study demonstrated that high serum GGT levels were an independent risk factor for all-cause mortality in PD patients. Our findings suggest that serum GGT levels might be a useful biomarker to predict all-cause mortality in PD patients. PMID:26252286

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

    Autoimmunity to brain may play an etiopathogenic role in autism. Osteopontin is a pro-inflammatory cytokine that has been shown to play an important role in various autoimmune neuroinflammatory diseases. Osteopontin induces IL-17 production by T-helper 17 lymphocytes, the key players in the pathogenesis of autoimmune disorders. Anti-osteopontin treatment reduces the clinical severity of some autoimmune neuroinflammatory diseases by reducing IL-17 production. We are the first to measure serum osteopontin levels, by ELISA, in 42 autistic children in comparison to 42 healthy-matched children. The relationship between serum osteopontin levels and the severity of autism, which was assessed by using the Childhood Autism Rating Scale (CARS), was also studied. Autistic children had significantly higher serum osteopontin levels than healthy controls (P<0.001). Increased serum osteopontin levels were found in 80.95% (34/42) of autistic children. Children with severe autism had significantly higher serum osteopontin levels than patients with mild to moderate autism (P=0.02). Moreover, serum osteopontin levels of autistic patients had significant positive correlations with CARS (P=0.007). In conclusions, serum osteopontin levels were increased in many autistic children and they were significantly correlated to the severity of autism. Further wide-scale studies are warranted to shed light on the etiopathogenic role of osteopontin in autism and to investigate its relation to IL-17 and brain-specific auto-antibodies, which are indicators of autoimmunity, in these patients. The therapeutic role of anti-osteopontin antibodies in amelioration of autistic manifestations should also be studied. PMID:21521652

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

    Exposure to microgravity has been associated with several physiological changes in astronauts and cosmonauts, including an osteoporosis-like loss of bone mass. It has been reported that head-down tilt bed-rest studies mimic many of the observations seen in flights. There is no study on the correlation on effects of mandibular bone and alveolar bone loss in both sex in simulating microgravity. This study was designed to determine the Bone mineral density and GCF MMP-8 MMP-9 in normal healthy subject of both sexes in simulated microgravity condition of -6 head-down-tilt (HDT) bed rest. The subjects of this investigation were 10 male and 10 female volunteers participated in three weeks 6 HDT bed-rest exposure. The Bone density and bone mineral contents were measured by dual energy X-ray absorptiometry before and in simulated microgravity. The GCF MMP-8 MMP-8 were measured by Enzyme-linked immunosorbent assays (Human Quantikine MMP-8,-9 ELISA kit). The bone mineral density and bone mineral contents levels were significantly decreased in simulated microgravity condition in both genders, although insignificantly loss was higher in females as compared to males. MMP-8 MMP-9 levels were significantly increased in simulated microgravity as compared to normal condition although insignificantly higher in females as compared to males. Further study is required on large samples size including all factors effecting in simulated microgravity and microgravity.

    Introduction: Prompt and accurate diagnosis of sepsis is of high importance for clinicians. Procalcitonine (PCT) and C-reactive protein (CRP) have been proposed as markers for this purpose. Our aim was to evaluate the levels of PCT and CRP in early sepsis and its correlation with severity of sepsis. Methods: Levels of PCT and CRP were taken from 60 patients with sepsis criteria and 39 patients with SIRS symptoms from the University Hospital Center “Mother Teresa” in Tirana, Albania during 2010-2012. Sensitivity, specificity and predictive values for PCT and CRP were calculated. Results: PCT and CRP levels increased in parallel with the severity of the clinical conditions of the patients. The mean PCT level in patients with sepsis was 11.28 ng/ml versus 0.272 ng/ml in patients with SIRS symptoms, with a sensitivity of 97.4% and a specificity of 96.6% for PCT >0.5ng/ml. The mean CRP level in septic patients was 146.58 mg/l vs. 34.4 mg/l in patients with SIRS, with a sensitivity of 98.6% for sepsis and a specificity of 75 % for CRP >11mg/l. Conclusion: PCT and CRP values are useful markers to determine early diagnosis and severity of an infection. In the present study, PCT was found to be a more accurate diagnostic parameter for differentiating SIRS from sepsis and may be helpful in the follow-up of critically ill patients. PMID:23687457

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

    The present study was conducted to compare the serum ferritin status between the postmenopausal vegetarians and non-vegetarians and to identify the relation of serum ferritin with metabolic syndrome (MetS) risk factors in postmenopausal women. The two study groups consisted of postmenopausal vegetarians (n=59) who maintained a vegetarian diet for over 20 years and age-matched non-vegetarian controls (n=48). Anthropometric measurements, dietary intakes, serum metabolic syndrome-related parameters, and serum ferritin level between the two groups were compared. The vegetarians exhibited significantly lower weight (p<0.01), body mass index (BMI) (p<0.001), percentage of body fat (p<0.001), waist circumference (p<0.01), SBP (p<0.001), DBP (p<0.001), and fasting glucose (p<0.05). According to the National Cholesterol Education Program (NCEP)-Adult Treatment Panel III criteria for MetS applying Korean guidelines for waist circumference, the prevalence of MetS was lower in vegetarians (33.9 %) than in non-vegetarians (47.9 %). Vegetarians had significantly lower serum level of ferritin (p<0.01) than non-vegetarians. In the correlation analysis, serum ferritin was positively related to fasting glucose (r=0.264, p<0.01), triglycerides (r=0.232, p<0.05), and the NCEP score (r=0.214, p<0.05) and negatively related to high-density lipoprotein-cholesterol (r=-0.225, p<0.05) after adjusting for BMI, lifestyle, and dietary factors (animal protein, animal fat, and dietary fiber intake). In conclusion, postmenopausal vegetarians had lower MetS presence and a lower serum ferritin level compared to non-vegetarians. Furthermore, vegetarians' low serum ferritin level may reduce the risk of MetS in postmenopausal women. PMID:22528775

    Objective: To evaluate the serum levels of zinc and copper in epileptic children during the long-term treatment of anticonvulsant drugs and correlate this with healthy subjects. Methods: A hospital-based group matched case-control study was conducted in the Department of Pediatrics, Faculty of Medicine, Zagazig University, Zagazig, Egypt between November 2013 and October 2014. Ninety patients aged 7.1±3.6 years were diagnosed with epilepsy by a neurologist. The control group was selected from healthy individuals and matched to the case group. Serum zinc and copper were measured by the calorimetric method using a colorimetric method kit. Results: The mean zinc level was 60.1±22.6 ug/dl in the cases, and 102.1±18 ug/dl in the controls (p<0.001). The mean copper level was 180.1±32.4 ug/dl in cases compared with 114.5±18.5 ug/dl in controls (p<0.001). Conclusion: Serum zinc levels in epileptic children under drug treatment are lower compared with healthy children. Also, serum copper levels in these patients are significantly higher than in healthy people. No significant difference in the levels of serum copper and zinc was observed in using one drug or multiple drugs in the treatment of epileptic patients. PMID:26492112

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

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

    microRNAs have emerged as powerful regulators of many biological processes, and their expression in many cancer tissues has been shown to correlate with clinical parameters such as cancer type and prognosis. Present in a variety of biological fluids, microRNAs have been described as a ‘gold mine’ of potential noninvasive biomarkers. Release of microRNA content of blood cells upon hemolysis dramatically alters the microRNA profile in blood, potentially affecting levels of a significant number of proposed biomarker microRNAs and, consequently, accuracy of serum or plasma-based tests. Several methods to detect low levels of hemolysis have been proposed; however, a direct comparison assessing their sensitivities is currently lacking. In this study, we evaluated the sensitivities of four methods to detect hemolysis in serum (listed in the order of sensitivity): measurement of hemoglobin using a Coulter® AcT diff™ Analyzer, visual inspection, the absorbance of hemoglobin measured by spectrophotometry at 414 nm and the ratio of red blood cell-enriched miR-451a to the reference microRNA miR-23a-3p. The miR ratio detected hemolysis down to approximately 0.001%, whereas the Coulter® AcT diff™ Analyzer was unable to detect hemolysis lower than 1%. The spectrophotometric method could detect down to 0.004% hemolysis, and correlated with the miR ratio. Analysis of hemolysis in a cohort of 86 serum samples from cancer patients and healthy controls showed that 31 of 86 (36%) were predicted by the miR ratio to be hemolyzed, whereas only 8 of these samples (9%) showed visible pink discoloration. Using receiver operator characteristic (ROC) analyses, we identified absorbance cutoffs of 0.072 and 0.3 that could identify samples with low and high levels of hemolysis, respectively. Overall, this study will assist researchers in the selection of appropriate methodologies to test for hemolysis in serum samples prior to quantifying expression of microRNAs. PMID:27054342

    Background: Preeclampsia in pregnancy has been shown to be associated with low serum calcium level. Though the evidence is abundant, it is equivocal. Objectives: The study aimed to estimate the dietary calcium intake and serum calcium status among pregnant women, and to document the association of the dietary calcium intake and serum calcium status with incidence of preeclampsia in the 3rd trimester of pregnancy. Materials and Methods: A community-based cross-sectional study was conducted in the Health and Demographic Surveillance System (HDSS) site, Ballabgarh, Haryana, India. All pregnant women between 28 weeks and 36 weeks of gestation were interviewed. A semi-structured interview schedule and a 24-h dietary recall questionnaire were administered to assess the dietary calcium intake. AutoAnalyser (Biolis 24i) was used for measuring serum calcium. Results: We enrolled 217 pregnant women. The mean [standard deviation (SD)] dietary calcium intake was 858 (377) mg/day. The mean (SD) serum calcium level was 9.6 mg/dL (0.56). Incidence of preeclampsia was 13.4%. Preeclampsia was not associated with hypocalcemia [odds ratio (OR) = 1.2 95% confidence interval (CI); 0.27-3.98]. Conclusion: The majority of pregnant women had inadequate dietary calcium intake. The prevalence of hypocalcemia was low. Low serum calcium level was not associated with preeclampsia. Calcium supplementation may not reduce preeclampsia in this population. PMID:27385877

    Circulating erythropoietin (EPO) is mainly derived from the kidneys, and the serum concentration is rapidly increased in response to anemia and hypoxia. The present study investigated postmortem serum EPO levels in injury death cases (n=185, postmortem time<48 h, survival time <7 days: sharp instrument injury, n=44 and blunt injury, n=141) with regard to survival time, compared with C-reactive protein (CRP) as a marker of inflammation. Serum levels of both markers were independent of postmortem time. A survival time-dependent increase in serum EPO up to about 100 mU/ml was seen within 6h of sharp instrument injury to the heart or a proximal major vessel (thoracic aorta or subclavian/carotid artery) and blunt injury with massive hemorrhages, showing high correlations (r=0.957 and r=0.822, respectively, P<0.0001), whereas the increase was insignificant (P>0.05) for sharp instrument injury to a peripheral vessel or lungs/abdominal viscera and blunt injury with minor hemorrhages over the same survival period. A further increase (>100 mU/ml) was often detected in cases of death about 24h after blunt injury, irrespective of the type of injury. In contrast, a gradual increase in serum CRP level was seen about 12-24h after blunt injury. These findings suggest that serum EPO can be a marker for investigating survival time within 6h of major injury involving acute massive hemorrhaging. PMID:20430543

    Background Serum alkaline phosphatase (ALP) levels have been reported to be associated with all-cause and cardiovascular mortality in peritoneal dialysis (PD) patients. However, it is unclear whether serum ALP levels predict infection-related clinical outcomes in PD patients. The aim of this study was to determine the relationships between serum ALP levels, infection-related mortality and hospitalization in PD patients. Methods PD patients from the Clinical Research Center registry for end-stage renal disease, a multicenter prospective observational cohort study in Korea, were included in the present study. Patients were categorized into three groups by serum ALP tertiles as follows: Tertile 1, ALP <78 U/L; Tertile 2, ALP = 78–155 U/L; Tertile 3, ALP >155 U/L. Tertile 1 was used as the reference category. The primary outcomes were infection-related mortality and hospitalization. Results A total of 1,455 PD patients were included. The median follow-up period was 32 months. The most common cause of infection-related mortality and hospitalization was PD-related peritonitis. Multivariate Cox regression analyses showed that patients in the highest tertiles of serum ALP levels were at higher risk of infection-related mortality (HR 2.29, 95% CI, 1.42–5.21, P = 0.008) after adjustment for clinical variables. Higher tertiles of serum ALP levels were associated with higher risk of infection-related hospitalization (Tertile 2: HR 1.56, 95% CI, 1.18–2.19, P = 0.009, tertile 3: HR 1.34, 95% CI, 1.03–2.62, P = 0.031). Conclusions Our data showed that elevated serum ALP levels were independently associated with a higher risk of infection-related mortality and hospitalization in PD patients. PMID:27310428

    Purpose Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to clarify whether a relationship exists between the serum levels of homocysteine and the behavioral and psychological symptoms of dementia. Methods Patients with Alzheimer’s disease (n=77) and control subjects (n=37) were included in this study. History taking, physical examination, and cognitive assessment were carried out as part of the investigation for the diagnosis of Alzheimer’s disease based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The Mini-Mental State Examination, Global Deterioration Scale, Clinical Dementia Rating, and the Korean version of the Neuropsychiatric Inventory were applied to all patients. The patients’ serum homocysteine, folate, and vitamin B12 levels were measured. Results Patients with Alzheimer’s disease had statistically significantly lower Mini-Mental State Examination scores and higher serum homocysteine levels compared to the control subjects. Mean serum folate and vitamin B12 concentration were significantly lower in patients with Alzheimer’s disease compared to control subjects. A statistically significant positive correlation was found between the serum homocysteine levels and the Neuropsychiatric Inventory subdomains, including delusion, agitation/aggression, depression/dysphoria, elation/euphoria, apathy/indifference, and disinhibition. No statistically significant correlation was found between the serum homocysteine concentration and the Mini-Mental State Examination, Global Deterioration Scale, or Clinical Dementia Rating. Conclusion Associations between the serum homocysteine levels and behavioral and psychological symptoms of dementia were observed, raising the possibility of an etiological role. However, the correlations between the folate or vitamin B12 levels and the Neuropsychiatric Inventory scores were not significant. The pathophysiological

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

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

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

    The authors developed a kit for the purpose of assessment of anti-rabies antibodies by the ELISA immunoenzymatic method in human immunized sera. The results of the detection and quantification of anti-rabies antibodies acquired by the ELISA method were compared with those originating from classical procedures (virusneutralizing test on mice, indirect hemagglutination test), and a sufficient correlation and sensitivity of the immunoenzymatic method were detected. By means of the developed test it is possible to detect the particular level of anti-rabies virusneutralizing IgG antibodies. (Tab. 2, Fig. 1, Ref. 25). PMID:7922630

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

    The objective of this study was to determine the levels of serum copper and zinc in subclinically hypocalcemic peripartum dairy cows in comparison to healthy animals. Blood samples were taken from 219 multiparous Holstein cows near parturition (from 4 weeks prepartum to 4 weeks postpartum) and 51 cows with subclinical hypocalcemia. The results showed that the serum copper concentration increased gradually at 1 week prepartum and remained high for the first 4 weeks postpartum in the healthy periparturient dairy cows. The serum zinc concentration reached a nadir at 1 week postpartum and subsequently increased gradually to baseline. The serum zinc concentration was significantly decreased (P<0.01) in dairy cows with subclinical hypocalcemia compared with healthy cows. There was no significant difference in the serum copper concentration between cows with subclinical hypocalcemia and healthy cows. These data demonstrate that the concentrations of copper and zinc in serum change dramatically during the peripartum period in dairy cows, which is a tremendous challenge for the body and for the maintenance of dairy cow health. The present study further suggests that a decreased serum zinc concentration could be a cause of decreased productive performance and increased susceptibility to other diseases due to immunosuppression in dairy cows with subclinical hypocalcemia. Additionally, this decreased zinc concentration may be involved in the pathogenesis of subclinical hypocalcemia. PMID:24859816

    We aimed to study the influences of active epilepsy and intellectual disability (ID) on the serum interleukin-6 (IL-6) by determining levels in 74 patients with developmental disorder with epilepsy and 63 healthy controls. The patients showed significantly higher IL-6 levels than the controls (4.1±4.5pg/ml vs. 2.1±1.0pg/ml; p<0.001). High seizure frequency and severe intellectual disability emerged as predictors for elevated serum levels of IL-6. PMID:21530175

    Exposure to endocrine disrupting chemicals (EDCs), particularly during developmental periods, gives rise to a variety of adverse health outcomes. Bisphenol A (BPA) is a well-known EDC commonly found in plastic products including food and water containers, baby bottles, and metal can linings. This study investigates infant exposure to BPA and the effect of bottle-feeding on serum BPA levels in infants. Serum BPA levels in normal healthy infants 6 to 15 months of age (n=60) were evaluated by a competitive ELISA. BPA was detected in every study sample. Serum BPA levels of bottle-fed infants (n=30) were significantly higher than those of breast-fed infants (n=30) (96.58±102.36 vs 45.53±34.05 pg/mL, P=0.014). There were no significant differences in serum BPA levels between boys (n=31) and girls (n=29). No significant correlations were found between serum BPA levels and age, body weight, birth weight, and gestational age. Bottle-feeding seems to increase the risk of infant exposure to BPA. Establishment of health policies to reduce or prevent BPA exposure in infants is necessary. PMID:24550655

    Objective Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent mental health disorders. In recent years, the impacts of various micronutrients on ADHD have been studied. However, vitamin D has received much less attention. This study was aimed at evaluating the association and level of serum vitamin D in children with ADHD. Materials & Methods This case-control study was carried out, in 2012, on 6 to 12 yr-old children. Thirty-seven were children with ADHD in the cases group and another 37 healthy children were in the control group. Venous blood sample was drawn from each child to measure the serum level of vitamin D. Other variables were compared as well. Results The mean serum vitamin D level of children with ADHD (19.11±10.10 ng/ml) was significantly lower than that of the control group (28.67±13.76 ng/ml) (P<0.001). Conclusion Deficiency of vitamin D has been proved in various psychiatric diseases. This study evidenced a significantly low level of serum vitamin D in children with ADHD. This suggests the need for regularly monitoring of serum vitamin D levels and treatment of patients with vitamin D deficiencies. PMID:26664441

    The objective of this study is to assess the serum IL-35 level and its association with clinical manifestations in patients with systemic sclerosis (SSc). IL-35 serum levels were measured by ELISA from 56 patients with SSc and 53 healthy controls. Association of IL-35 serum levels were sought with clinical parameters. Serum IL-35 levels were significantly higher in SSc patients (5.08 ± 0.76 pg/ml) than in healthy individuals (1.89 ± 0.69 pg/ml; p < 0.0001). Patients with lung fibrosis had higher IL-35 levels than those without fibrosis (7.75 ± 1.36 and 3.08 ± 0.70 pg/ml, respectively, p = 0.0022). IL-35 is elevated in the serum of patients with SSc and is associated with lung fibrosis. Our findings suggest that this cytokine can have a role in fibrotic diseases, but further studies are needed to address the role of IL-35 in the pathogenesis of SSc. PMID:26160266

    Involvement of 25-hydroxyvitamin D in the etiopathogenesis of tonsillar disease in children is still debated; this study assesses possible differences in serum 25-hydroxyvitamin D levels between 309 Caucasian children (58.1% males; mean age 55.7 ± 31.0 months) living in Milan with a history of recurrent tonsillitis (RT) and healthy controls. Mean serum 25(OH)D levels were significantly reduced in the children with a history of RT (22.0 ± 8.7 ng/mL vs 24.6 ± 7.8 ng/mL; p=0.03), and the proportion of children with insufficient or deficient serum 25(OH)D levels was higher in the RT group (81.5% and 6.5% respectively) than in the control group (75.1% and 3.5%) (not significant). The multivariable model created to test the independent association between serum 25(OH)D levels and a history of RT after adjusting for age and season showed that the association was not significant. Our study failed to find any significant reduction in serum 25(OH)D levels after adjustment for age and season in a case series of children with RT in comparison with healthy controls, which suggests that vitamin D does not play a relevant role in the etiology of pediatric tonsillar infections.

    Stress has inhibitory effect on HPG axis through increasing cortisol serum level. In this study, the effect of acute prepubertal stress on kisspeptin, which plays essential role in puberty achievement is assessed. To do this experimental study thirty immature healthy male wistar rats of 4 weeks old and without any symptoms of puberty were selected randomly. These rats were divided into three groups, randomly. Two groups were chosen as control and pretest and one as stress (test) group. Immobilization stress was applied for 10 days and serum level of cortisol, testosterone and kisspeptin were measured. Primary and secondary spermatocyte and sertoli cell evaluated and compared among groups. Mean serum level of kisspeptin in pretest group, control group and stress (test) group were 0.0381 ± 0.0079, 91.0500 ± 4.87430 and 15.2156 ± 3.88135 pg mL(-1) respectively. Serum level of kisspeptin had significant differences between three groups (p < 0.001). Acute prepubertal immobilization stress led to decrease in serum level of kisspeptin and testosterone in stress (test) group compared to control groups. Also stress caused a significant decrease in the numbers of secondary spermatocytes of the test group. PMID:26930799

    High serum uric acid (UA) levels are believed to be an independent risk factor for the development of diabetes. We aimed to investigate the relationship between serum UA concentrations and early-phase insulin secretion following a 75 g oral glucose tolerance test (OGTT) in nondiabetic subjects. We enrolled 570 Japanese subjects (354 males and 216 females, aged 50.5 ± 8.9 years and 52.6 ± 7.3 years, respectively), who underwent the 75 g OGTT during their annual health examination. The OGTT confirmed their nondiabetic status. Insulin secretion was estimated by the disposition index (DI) [(Δ insulin/Δ glucose (0-30 min) × (1/HOMA-IR)], which is an adjusted measure of β-cell function relative to variations in insulin sensitivity. Simple linear regression analysis showed negative correlations between serum UA levels and DI, when examined in the whole study population and female subjects only (r = -0.209, p < 0.001 and r = -0.232, p < 0.001, respectively). However, in male subjects, UA levels did not correlate with DI. In females, multivariate linear regression analysis revealed that serum UA levels were the major predictors of DI, explaining 16.4% of its variation (p < 0.001). Serum UA levels significantly correlate with early-phase insulin secretion in nondiabetic Japanese women. It may be an independent risk factor for predicting β-cell function in women. PMID:25295417

    Low serum 25-hydroxyvitamin D (25OHD) is associated with osteoporosis and osteoporotic fracture, but it remains uncertain whether these associations are causal. We conducted a Mendelian randomization (MR) study of 1,824 postmenopausal Chinese women to examine whether the detected associations between serum 25OHD and bone mineral density (BMD) and bone metabolism markers were causal. In observational analyses, total serum 25OHD was positively associated with BMD at lumbar spine (P = 0.003), femoral neck (P = 0.006) and total hip (P = 0.005), and was inversely associated with intact parathyroid hormone (PTH) (P = 8.18E-09) and procollagen type 1 N-terminal propeptide (P1NP) (P = 0.020). By contract, the associations of bioavailable and free 25OHD with all tested outcomes were negligible (all P > 0.05). The use of four single nucleotide polymorphisms, GC-rs2282679, NADSYN1-rs12785878, CYP2R1-rs10741657 and CYP24A1-rs6013897, as candidate instrumental variables in MR analyses showed that none of the two stage least squares models provided evidence for associations between serum 25OHD and either BMD or bone metabolism markers (all P > 0.05). We suggest that after controlling for unidentified confounding factors in MR analyses, the associations between genetically low serum 25OHD and BMD and bone metabolism markers are unlikely to be causal.

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

    Interleukin-33 (IL-33) is a cytokine that belongs to the interleukin-1 family and has been shown to be associated with mucosal inflammation. The aim of this study was to determine the serum level of IL-33 in children with ulcerative colitis (UC) and Crohn’s disease (CD) and to correlate the level with the disease progression. In this cross sectional prospective study, we enrolled 50 children with IBD from KAUH, Jeddah, Saudi Arabia and 34 healthy control subjects between June 2012 and December 2012. Serum IL-33 was assessed by ELISA and CRP by immunonephelometric assay. Results from our study showed 32 CD and 18 UC patients included. The median age was 13.5 years for CD patients, 11.9 years for UC patients and 11.2 years for controls. Females constituted 53%, 66.7% and 59% of CD, UC and control subjects respectively. The median serum IL-33 in UC patients of 55.5 pg/mL was significantly higher than the median IL-33 level of 41 pg/mL in the healthy control (P=0.04) but no significant difference was found between the median IL-33 level in the sera of CD and the control group (P=0.7). A higher median IL-33 level was also found in active disease (P=0.03). In our cohort, the serum level of IL-33 was positively correlated with hs-CRP (r=0.48, P < 0.001). To conclude, our results support that serum IL-33 level is increased in children with UC as compared with control. Serum level is correlated with the disease activity; therefore it could be used as a potential biomarker for monitoring the severity of the disease in children with UC. PMID:26884875

    Purpose In diabetes, an impaired antioxidant defense system contributes to the development of diabetic retinopathy. The main objective of this paper was to find correlations of oxidative stress parameters within and between the vitreous and serum in patients with type 2 diabetes who had developed proliferative diabetic retinopathy. Methods The study included and compared two groups of patients who underwent vitrectomy: 37 patients with type 2 diabetes and proliferative retinopathy (PDR), and 50 patients with non-diabetic eye disorders (NDED). Vascular endothelial growth factor (VEGF), advanced oxidized protein product (AOPP), and oxidative stress markers (direct lipid hydroperoxidation (LPO), malondialdehyde (MDA), total superoxide dismutase (SOD), and glutathione (GSH)) were measured in the vitreous and serum of both groups and correlated with one another, between humoral compartments and with gender, age, and serum glucose levels. Results In the vitreous of PDR patients, VEGF, LPO, and MDA (p<0.05) were increased and SOD values were slightly lowered (p<0.05) than in NDED patients. Vitreous AOPP and GSH showed no differences between the groups. In the serum, AOPP, MDA, and SOD were increased (p<0.05) and VEGF was slightly increased (p<0.05) in the PDR group compared to NDED. With regard to gender, similar changes were recorded for both groups, except for the lower serum MDA in males than females in the NDED group. Advanced age showed no significant effect on changes of measured parameters in the vitreous. In the serum, VEGF was positively correlated (p<0.05) and MDA and SOD negatively correlated (p<0.05) with increasing age. Among measured parameters within and between the vitreous and serum, several correlative links occurred in the PDR group that were not present in the NDED group. The most prominent correlation changes were between serum LPO and vitreal LPO, serum SOD and vitreal LPO, serum LPO and serum SOD, and vitreal VEGF and serum SOD. Conclusions Among

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

    Narcolepsy is a lifelong sleep disorder characterized by excessive daytime sleepiness, sudden loss of muscle tone (cataplexy), fragmentation of nocturnal sleep and sleep paralysis. The symptoms of the disease strongly correlate with a reduction in hypocretin levels in CSF and a reduction in hypocretin neurons in hypothalamus in post-mortem tissue. Brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are important for activity-dependent neuronal function and synaptic modulation and it is considered that these mechanisms are important in sleep regulation. We hypothesized that serum levels of these factors are altered in patients with narcolepsy compared to healthy controls without sleep disturbances. Polysomnography data was obtained and serum BDNF and NGF levels measured using ELISA, while hypocretin was measured using RIA. Serum BDNF levels were significantly higher in narcolepsy patients than in healthy controls (64.2±3.9 ng/ml vs. 47.3±2.6 ng/ml, P<0.01), while there were no significant differences in NGF levels. As expected, narcolepsy patients had higher BMI compared to controls, but BMI did not correlate with the serum BDNF levels. The change in BDNF levels was not related to disease duration and sleep parameters did not correlate with BDNF in narcolepsy patients. The mechanisms behind the marked increase in BDNF levels in narcolepsy patients remain unknown. PMID:23570723

    Cerebral hypometabolism of glucose, weight loss, and decreased food intake are characteristic features of sporadic Alzheimer's disease (AD). A systematic study on the serum levels of adipokines and insulin, the major hormones regulating energy metabolism, food intake, and body weight, in sporadic AD is necessary. The present study compares the serum levels of leptin, adiponectin, and insulin, measured by commercially available immuno-assay kits, between controls and sporadic AD subjects. The results show a conspicuous decrease in the level of leptin, a dramatic rise in the level of adiponectin, and also a statistically significant increase in insulin level, in the blood of AD subjects, with respect to controls. The changes in the serum levels of adiponectin and insulin in AD are positively correlated with the severity of dementia. Likewise, the serum level of leptin in AD subjects is negatively correlated with the degree of dementia. The changes in the levels of adipokines and insulin have implications in the amyloid pathology, neurodegeneration, and hypometabolism of glucose existing in the AD brain. PMID:24625795

Herein, we evaluated the role of pantetheinase on erythrocyte homeostasis and on the development of malaria in patients and in a new mouse model of pantetheinase insufficiency. Patients with cerebral malaria have significantly reduced levels of serum pantetheinase activity (PA). In mouse, we show that a reduction in serum PA predisposes to severe malaria, including cerebral malaria and severe anemia. Therefore, scoring pantetheinase in serum may serve as a severity marker in malaria infection. This disease triggers an acute stress in erythrocytes, which enhances cytoadherence and hemolysis. We speculated that serum pantetheinase might contribute to erythrocyte resistance to stress under homeostatic conditions. We show that mutant mice with a reduced serum PA are anemic and prone to phenylhydrazine-induced anemia. A cytofluorometric and spectroscopic analysis documented an increased frequency of erythrocytes with an autofluorescent aging phenotype. This is associated with an enhanced oxidative stress and shear stress-induced hemolysis. Red blood cell transfer and bone marrow chimera experiments show that the aging phenotype is not cell intrinsic but conferred by the environment, leading to a shortening of red blood cell half-life. Therefore, serum pantetheinase level regulates erythrocyte life span and modulates the risk of developing complicated malaria. PMID:26343328

    Trichloroethylene (TCE) has been associated with a variety of immunotoxic effects and may be associated with an increased risk of non-Hodgkin lymphoma (NHL). Altered serum immunoglobulin (Ig) levels have been reported in NHL patients and in animals exposed to TCE. Recently, we reported that occupational exposure to TCE is associated with immunosuppressive effects and immune dysfunction, including suppression of B-cell counts and activation, even at relatively low levels. We hypothesized that TCE exposure would also affect Ig levels in humans. We measured serum levels of IgG, IgM and IgE, by enzyme-linked immunosorbent assay, in TCE-exposed workers (n = 80) and unexposed controls (n = 45), matched by age and gender, in a cross-sectional, molecular epidemiology study of occupational exposure to TCE in Guangdong, China. Exposed workers had about a 17.5% decline in serum levels of IgG compared with unexposed controls (P = 0.0002). Similarly, serum levels of IgM were reduced by about 38% in workers exposed to TCE compared with unexposed controls (P < 0.0001). Serum levels of both IgG and IgM were significantly decreased in workers exposed to TCE levels below 12 p.p.m., the median exposure level. Adjustment for B-cell counts had minimal impact on our findings. IgE levels were not significantly different between exposed and control subjects. These results provide further evidence that TCE is immunotoxic at relatively low exposure levels and provide additional biologic plausibility for the reported association of TCE with NHL.

    The recent discovery and clinical development of targeted agents have expanded treatment options in metastatic renal cell carcinoma (RCC). However, metastatic RCC remains a lethal disease. Complete response is rare and treatment with targeted agents eventually fails in the majority of the patients. Therefore, there is a need for developing a prognostic tool and a novel therapeutic agent for RCC to improve the follow-up strategy after surgical treatment. Clinical data, including patient characteristics, serum fatty acid profile, clinicopathological parameters and clinical outcome, were obtained from 112 patients with RCC prior to surgical treatment. Preoperative fatty acid levels were grouped according to patient characteristics, such as performance status, body mass index or pathological parameters, and were analyzed using the Mann-Whitney U test. Cancer-specific survival in the high and low docosahexaenoic acid (DHA) level groups were compared using the Kaplan-Meier method. Cox proportional hazards models were applied to determine the independent prognostic factors associated with shortened cancer-specific survival. The serum DHA level in patients with metastasis was significantly lower compared with that in patients without metastasis (P=0.047). Low serum DHA level, presence of metastasis and cachexia were independent predictors of shortened cancer-specific survival in a multivariate Cox proportional hazard model (P=0.033, hazard ratio = 4.43). Patients with a serum DHA level below the median value exhibited significantly shorter cancer-specific survival compared with those with a higher serum DHA level (P=0.008). Thus, according to our results, the preoperative serum DHA level may be able to predict the surgical outcome of RCC. However, this finding requires validation by large-scale prospective studies.

    The northeast Nile Delta region exhibits a high incidence of early-onset pancreatic cancer. It is well documented that this region has one of the highest levels of pollution in Egypt. Epidemiologic studies have suggested that cadmium, a prevalent pollutant in the northeast Nile Delta region, plays a role in the development of pancreatic cancer. Objective: We aimed to assess serum cadmium levels as markers of exposure in pancreatic cancer patients and noncancer comparison subjects from the same region in Egypt. Design and Participants: We assessed serum cadmium levels of 31 newly diagnosed pancreatic cancer patients and 52 hospital comparison subjects from Mansoura, Egypt. Evaluation/Measurements: Serum cadmium levels were measured using a novel immunoassay procedure. Results: We found a significant difference between the mean serum cadmium levels in patients versus comparison subjects (mean ± SD, 11.1 ± 7.7 ng/mL vs. 7.1 ± 5.0 ng/mL, respectively; p = 0.012) but not in age, sex, residence, occupation, or smoking status. The odds ratio (OR) for pancreatic cancer risk was significant for serum cadmium level [OR = 1.12; 95% confidence interval (CI), 1.04–1.23; p = 0.0089] and farming (OR = 3.25; 95% CI, 1.03–11.64; p = 0.0475) but not for age, sex, residence, or smoking status. Conclusions: The results from this pilot study suggest that pancreatic cancer in the East Nile Delta region is significantly associated with high levels of serum cadmium and farming. Relevance to Clinical Practice/Public Health: Future studies should further investigate the etiologic relationship between cadmium exposure and pancreatic carcinogenesis in cadmium-exposed populations.

    A study was undertaken in 38 menopausal women on-cyclic HRT (estropipate) and estropipate + nor-ethindrone). Serum estradiol levels during treatment were related to mood changes and platelet MAO activity. The relationship between serum estradiol levels and mood changes was found to be a function of the duration of menopause. Women with a short duration of menopause (12.9 months +/- 6.1) were compared to women with a long duration of menopause (76.6 months +/- 52.3). Women with a short duration of menopause had significantly lower mean serum estradiol levels during HRT compared to women with a long duration of menopause (216.9 +/- 62.3 vs. 291.13 +/- 118.12, respectively, p < .02). It had previously been reported that estrogen treatment in menopausal women had a positive effect on mood, whereas the combination of estrogen plus a progestin had a negative effect on mood. We found that the women with a long duration of menopause and higher treatment serum estradiol levels had significantly more dysphoria when receiving a combination of estrogen plus progestin than did the women with a short duration of menopause and lower serum estradiol levels. However, both short and long duration menopausal groups showed improvement in mood when estrogen was administered alone. Platelet MAO levels, a marker of adrenergic and serotonergic function thought to relate to mood, were negatively correlated with serum estradiol levels during HRT. We suggest that these paradoxical findings may be secondary to a prolonged estrogen deficiency state in women with a long duration of menopause. PMID:9373888

    Background: Female pattern hair loss (FPHL) is the most common cause of alopecia in women, characterized by diffuse nonscarring hair loss in frontal, central, and parietal areas of the scalp. Pathophysiology of FPHL is still not well known, and it is probably a multifactorial genetic trait. FPHL is also observed in women without increased androgen levels, which raises the likelihood of androgen-independent mechanisms and explains the lack of response to antiandrogen treatments in some patients. Vitamin D is a factor that has recently been considered in dealing with these patients. The purpose of this study was to evaluate the serum levels of Vitamin D in patients with FPHL and compare it with healthy controls. Methods: In this case-control study, 45 women with FPHL were evaluated as well as the same number of healthy women matched for age, hours spent under sunlight per day, and body mass index. Serum 25(OH) D3 level was measured using ELISA. Results: 60% of FPHL patients were in 15–30 years old age group with the mean standard deviation (SD) age of 29.11 (7.30) years. In the majority of patients (66.7%), severity of hair loss was Ludwig I. Mean (SD) serum Vitamin D3 level in patient and control group was 13.45 (8.40) and 17.16 (8.96), respectively. T-test showed a significant difference between the two groups in terms of Vitamin D3 serum levels (P = 0.04). Conclusions: This study indicated the correlation between the incidence of FPHL and decreased serum levels of Vitamin D3. It is recommended to evaluate serum Vitamin D3 levels as well as other hormone assays in these patients. PMID:27625563

    Background The aim of this study was to assess the serum zinc levels in patients with common oral mucosal diseases by comparing these to healthy controls. Material and Methods A total of 368 patients, which consisted of 156 recurrent aphthous stomatitis (RAS) patients, 57 oral lichen planus (OLP) patients, 55 burning mouth syndrome (BMS) patients, 54 atrophic glossitis (AG) patients, 46 xerostomia patients, and 115 sex-and age-matched healthy control subjects were enrolled in this study. Serum zinc levels were measured in all participants. Statistical analysis was performed using a one-way ANOVA, t-test, and Chi-square test. Results The mean serum zinc level in the healthy control group was significantly higher than the levels of all other groups (p < 0.001). No individual in the healthy control group had a serum zinc level less than the minimum normal value. However, up to 24.7% (13/54) of patients with AG presented with zinc deficiency, while 21.2% (33/156) of patients with RAS, 16.4% (9/55) of patients with BMS, 15.2% (7/46) of patients with xerostomia, and 14.0% (8/57) of patients with OLP were zinc deficient. Altogether, the zinc deficiency rate was 19.02% (70/368) in the oral mucosal diseases (OMD) group (all patients with OMD). The difference between the OMD and healthy control group was significant (p <0.001). Gender differences in serum zinc levels were also present, although not statistically significant. Conclusions Zinc deficiency may be involved in the pathogenesis of common oral mucosal diseases. Zinc supplementation may be a useful treatment for oral mucosal diseases, but this requires further investigation; the optimal serum level of zinc, for the prevention and treatment of oral mucosal diseases, remains to be determined.

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

    Objectives To explore whether the levels of IFN-γ in cerebral spinal fluid (CSF) and serum are elevated in ALS patients and to analyze the correlations between the IFN-γ levels and disease progression. Methods CSF and serum samples were obtained from 52 ALS patients and 31 non-ALS patients. The levels of IFN-γ in CSF and serum were assessed, and disease progression parameters, including the disease interval (months from onset, MFO), the revised ALS Functional Rating Scale (ALSFRS-r) score and the disease progression rate (DPR) were analyzed by registered neurologists. All samples were measured using a commercial enzyme-linked immunosorbent assay. Statistical analyses were performed using Prism software. Results Compared to the non-ALS patients, the ALS patients displayed significantly increased levels of IFN-γ in both CSF and serum, and these values consistently correlated with disease progression. Conclusions These results demonstrated that IFN-γ in CSF may serve as a biomarker of ALS differentiation and progression. CSF IFN-γ was a more reliable biomarker of disease diagnosis and progression than serum IFN-γ. PMID:26332465

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

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

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

    Background Visceral leishmaniasis (VL), one of the neglected tropical diseases, is endemic in the Indian subcontinent. Ficolins are circulating serum proteins of the lectin complement system and involved in innate immunity. Methods We have estimated ficolin-2 serum levels and analyzed the functional variants of the encoding gene FCN2 in 218 cases of VL and in 225 controls from an endemic region of India. Results Elevated levels of serum ficolin-2 were observed in VL cases compared to the controls (adjusted P<0.0001). The genetic analysis revealed that the FCN2 structural variant +6359 C>T (p.T236M) was associated with VL (OR=2.2, 95% CI=1.23-7.25, P=0.008) and with high ficolin-2 serum levels. We also found that the FCN2*AAAC haplotype occurred more frequently among healthy controls when compared to cases (OR=0.59, 95%CI=0.37-0.94, P=0.023). Conclusions Our findings indicate that the FCN2 variant +6359C>T is associated with the occurrence of VL and that ficolin-2 serum levels are elevated in Leishmania infections. PMID:25965808

    Serum markers can be important tools for prognostic classification and treatment monitoring in cancer patients. The MAP-kinase pathway, which is upregulated in the majority of melanoma patients, can be activated by hepatocyte-growth factor (HGF) through the proto-oncogene c-MET. The aim of this study was to evaluate the predictive and prognostic value of circulating HGF in terms of treatment outcome and survival compared with a widely established serum marker, protein S-100B, in patients with advanced metastatic melanoma. HGF and S-100B were measured in serum samples of 101 patients with metastatic melanoma (American Joint Committee on Cancer stage IV) before and after treatment and 50 patients with stage I/II melanoma. HGF and S-100B correlated significantly with the stage of disease (P=0.032 and P<0.001, respectively). In stage IV melanoma patients, baseline serum levels of HGF and S-100B were significantly associated with treatment response (P=0.012 and 0.006, respectively). Furthermore, the Cox regression analysis confirmed that serum levels of HGF and S-100B proved to have a significant prognostic impact on progression-free survival (hazard ratio=1.39 and 1.29, respectively) and overall survival (hazard ratio=1.27 and 1.29, respectively) in advanced metastatic melanoma patients. In melanoma patients, serum levels of HGF and S-100B correlate significantly with the stage of disease. In stage IV melanoma, both markers are prognostic factors and correlate significantly with progression-free survival and overall survival. Measurement of serum HGF levels might be a useful additional tool in the management of melanoma patients. PMID:27206057

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

    Background Laparoscopic cholecystectomy (LC) requires the creation of a pneumoperitoneum via insufflations of carbon dioxide; resulting in increased partial pressure of carbon dioxide (CO2) and intraperitoneal pressure which leads to the changes in pulmonary function and hemodynamic measurements. Hypercarbia leads to visceral organ ischemia including liver and venous stasis/thromboembolism or both due to impaired flow. The present study has been undertaken to see the changes in liver function tests (LFTs) after laparoscopic/open cholecystectomy (OC), the incidences of such change, their relation to age, sex, duration of surgery and to know the clinical significances of such disturbances. Aims and objectives To compare and correlate the serum level of bilirubin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) in patients who underwent LC to those who underwent OC. Materials and methods The present study was conducted in the Department of Surgery at MMIMSR, MM University, Mullana, Ambala. A total number of 200 patients diagnosed as cholelithiasis were included in the study from May 2012 to May 2014. These cases were randomly divided into two groups (A and B) consisting of 100 cases each. LC was performed in group A patients and OC was done in group B patients. Three blood samples were taken: (I) pre-operatively; (II) after 24 hours of surgery; and (III) after 72 hours of surgery for comparison of the enzyme level alterations. Results In LC patients, there were rise in the levels of serum bilirubin, AST and ALT after 24 hrs of surgery from the preoperative value and then again fall was noted (near to normal value) after 72 hrs of surgery except in that of ALP. ALP levels showed slight fall after 24 hrs of surgery and then slight rise after 72 hrs which was within the normal limit. Whereas in OC patients, there were slight variations in the liver enzymes (which were within the normal range). Conclusions Transient elevation of serum

    High level of the CA 125 serum antigen is typically associated with ovarian malignancies. However the CA 125 antigen can also be found in association with inflammation or neoplasms of tissues other than ovaries, i.e. mesothelial cells, mullerian duct derivatives and gastroenteric tract. Therefore the marker is not specific for ovarian neoplasms. In childhood there is not a large experience about clinical meaning of high CA 125 serum levels. We report a case in a 14-year-old patient, female, affected by hydronephrosis. Our case confirms that high CA 125, especially in childhood, is not necessarily associated with ovarian or pelvic diseases. Moreover the review of literature suggests the opportunity to investigate CA 125 serum levels in children affected by hydronephrosis. PMID:8965765

    Carbohydrate antigen 19-9 (CA 19-9) is a sensitive marker for pancreatic and hepatobiliary malignancies. The highest frequency of elevated serum CA 19-9 levels is found among patients with pancreatic cancer. CA 19-9 has recently been demonstrated to be a marker of digestive tract malignancies. We report the case of a patient with a gastric cancer and a very high serum CA 19-9 level. During laparotomy, a large mass was found in the antrum. A distal gastrectomy with D2 dissection of the lymph nodes was performed. Histological examination, including immunohistochemistry, revealed an adenocarcinoma of the stomach producing CA 19-9. To the best of our knowledge, no patient with an extremely high serum CA 19-9 level resulting from a gastric adenocarcinoma has been reported previously. PMID:21577374

    Interleukin-18 (IL-18), a pro-inflammatory cytokine that plays an important role in the T-cell-helper type 1 response, is a new member of the family of cytokines produced in the brain. CD30 is a marker of T-cell-helper type 2 lymphocytes. We evaluated IL-18 and CD30 serum levels in 10 patients affected by moderate-severe depression (MSD). We demonstrated for the first time that serum IL-18 levels of MSD patients were significantly higher than those of healthy donors. On the contrary, no significant difference was found between serum CD30 levels of MSD patients compared with those of healthy donors. These data strengthen the hypothesis that MSD disease is associated with an inflammatory response, mainly T-cell-helper type 1, and suggest an important role for IL-18 in the pathophysiology of MSD.

    Background. Osteopontin (OPN) has been proved to be associated with allergic airway inflammation. However, the roles of OPN and its regulation in childhood allergic rhinitis (AR) are poorly understood. Objective. This study aims to evaluate the expression of OPN and miR-181a in children with AR and their association with Th1/Th2 immune response. Methods. Children who suffered from AR were included along with control subjects. Serum was collected to examine the level of OPN and Th1/Th2 cytokines by enzyme-linked immunosorbent assay (ELISA) and the level of miR-181a by quantitative polymerase chain reaction (qPCR). Results. Children with AR had significantly higher serum levels of OPN and lower serum levels of miR-181a than healthy controls. Furthermore, serum levels of OPN were positively correlated with Th2 cytokine and negatively correlated with Th1 cytokine. On the contrary, miR-181a level had a negative correlation with IL-4/IL-5 and positive correlation with IFN-γ/IL-12. More importantly, there was also significant negative correlation between OPN and miR-181a. Conclusion. The OPN protein and miR-181a levels may serve as predictors of disease severity in childhood AR and appear to be promising targets for modulating AR. PMID:27199509

    Objective: Cancerous cells show increased glycolysis rate. This will increase overall levels of pyruvate as it is one of the end products of glycolysis. The present on-going study is to estimate the levels of pyruvate in saliva and serum among healthy and oral cancer subjects. Settings and Design: Hospital-based cross-sectional comparative study. Methodology: A total of 50 subjects among healthy and oral cancer subjects were selected based on clinical and histological criteria. Saliva and serum samples were collected and subjected to pyruvate level estimation using biochemical analysis. Statistical Analysis: Descriptive analysis and Mann-Whitney test were used to find the statistical difference between the two independent groups. Results: Serum pyruvic acid levels of the healthy group were 1.09 ± 0.14 and for oral cancer, it was 2.95 ± 0.59 and salivary level were 3.49 ± 0.47 and 1.32 ± 0.10 respectively. Mann-Whitney test showed statistically significant difference in serum and salivary pyruvate level in between two groups (P < 0.000 respectively). Conclusion: The present study showed noticeable variation in the level of pyruvic acid among healthy and oral cancer subjects. This generates the hypothesis that estimation of the pyruvic acid can be a new tool to screening of the cancer. PMID:27194870

    Background: Endostatin, a fragment of collagen XVIII, is an endogenous angiogenesis inhibitor with anti-tumour functions. However, elevated circulating endostatin concentrations have been found in several human cancers including colorectal cancer (CRC). Methods: Serum endostatin levels were measured by enzyme-linked immunoassay from a series of 143 patients with CRC and from 84 controls, and correlated with detailed clinicopathological features of CRC, serum leukocyte differential count and C-reactive protein (CRP) levels. Results: Patients with CRC had higher serum endostatin levels than the controls (P=0.005), and high levels associated with age, tumour invasion through the muscularis propria and poor differentiation, but not with metastases. Endostatin levels showed a positive correlation with the markers of systemic inflammatory response and a negative correlation with the densities of tumour-infiltrating mast cells and dendritic cells. Collagen XVIII was expressed in tumour stroma most strikingly in blood vessels and capillaries, and in the muscle layer of the bowel wall. Conclusions: Elevated endostatin levels in CRC correlate with systemic inflammation and invasion through the muscularis propria. Increased endostatin level may be a result of invasion-related cleavage of collagen XVIII expressed in the bowel wall. The negative correlations between serum endostatin and intratumoural mast cells and immature dendritic cells may reflect angiogenesis inhibition by endostatin. PMID:25137019

    Background Schizophrenia is a chronic and debilitating disorder, the etiology of which remains unclear. Apoptosis is a programmed cell death mechanism that might be implicated in neuropsychiatric disorders, including schizophrenia. In this study, we aimed to compare the serum levels of apoptosis among deficit schizophrenia (DS) syndrome patients, nondeficit schizophrenia (NDS) patients, and healthy controls (HCs). Patients and methods After the inclusion and exclusion criteria were applied, 23 DS patients, 46 NDS patients, and 33 HCs were included in the study. The serum apoptosis levels were measured using a quantitative sandwich enzyme immunoassay with human monoclonal antibodies directed against DNA and histones. Results There was a significant difference among the three groups in terms of the levels of apoptosis (F2,96=16.58; P<0.001). The serum apoptosis levels in the DS and NDS groups were significantly higher than those in the HC group. Furthermore, the serum apoptosis levels in the DS group were significantly higher than the levels in the NDS group. Conclusion This study suggests that increased levels of apoptosis may be implicated in the pathophysiology of DS syndrome. However, further studies are needed to support the role of apoptosis in DS.

    Introduction Emphysema and idiopathic pulmonary fibrosis (IPF) present either per se or coexist in combined pulmonary fibrosis and emphysema (CPFE). Serum surfactant proteins (SPs) A, B, C and D levels may reflect lung damage. We evaluated serum SP levels in healthy controls, emphysema, IPF, and CPFE patients and their associations to disease severity and survival. Methods 122 consecutive patients (31 emphysema, 62 IPF, and 29 CPFE) and 25 healthy controls underwent PFTs, ABG-measurements, 6MWT and chest HRCT. Serum levels of SPs were measured. Patients were followed-up for 1-year. Results SP-A and SP-D levels differed between groups (p = 0.006 and p<0.001 respectively). In post-hoc analysis, SP-A levels differed only between controls and CPFE (p<0.05) and CPFE and emphysema (p<0.05). SP-D differed between controls and IPF or CPFE (p<0.001 for both comparisons). In IPF SP-B correlated to pulmonary function while SP-A, correlated to the Composite Physiological Index (CPI). Controls current smokers had higher SP-A and SP-D levels compared to non-smokers (p = 0.026 and p = 0.023 respectively). SP-D levels were higher in CPFE patients with extended emphysema (p = 0.042). In patients with IPF, SP-B levels at the upper quartile of its range (≥26 ng/mL) presented a weak association with reduced survival (p = 0.05). Conclusion In conclusion, serum SP-A and SP-D levels were higher where fibrosis exists or coexists and related to disease severity, suggesting that serum SPs relate to alveolar damage in fibrotic lungs and may reflect either local overproduction or overleakage. The weak association between high levels of SP-B and survival needs further validation in clinical trials. PMID:27337142

    Pyrroloquinoline quinone (PQQ) is a water-soluble quinone compound that has a strong anti-oxidant capacity. A previous study in rats fed a PQQ-depleted diet showed that elevated levels of serum triglyceride (TG) decreased after PQQ supplementation. However, there is only one study reporting the effects of PQQ on serum lipid levels, such as those of TG and cholesterol, in humans. In this study, the effects of PQQ disodium salt (BioPQQ™) on serum TG and cholesterol levels in humans after 6 and 12 wk of treatment at an oral dosage of 20 mg/d were examined. This trial was conducted according to a randomized, placebo-controlled, double-blinded protocol. A total of 29 healthy Japanese adults, ranging from 40 to 57 y old, with normal to moderately high TG levels (110-300 mg/dL) as measured by a recent blood examination, were included in this study. In eleven volunteers out of 29, serum low-density lipoprotein cholesterol (LDL-chol) levels at baseline were high (≥140 mg/dL). After 12 wk, the mean serum TG levels had not changed; however, a marginally significant decrease in the mean LDL-chol (from 136.1 to 127.0 mg/dL) was observed in the PQQ group. In the stratification analysis of the high LDL-chol subgroup (baseline LDL-chol level ≥140 mg/dL), the mean LDL-chol levels decreased significantly from the baseline values in the PQQ group compared to the placebo group. Our study findings suggest that PQQ suppressed the LDL-chol level, which is an important finding, because a high level of this lipid is a risk factor for various lifestyle-related diseases.

    Objective: To determine whether serum selenium levels are associated with the conversion of bacteriological tests in patients diagnosed with active pulmonary tuberculosis after eight weeks of standard treatment. Methods: We evaluated 35 healthy male controls and 35 male patients with pulmonary tuberculosis, the latter being evaluated at baseline, as well as at 30 and 60 days of antituberculosis treatment. For all participants, we measured anthropometric indices, as well as determining serum levels of albumin, C-reactive protein (CRP) and selenium. Because there are no reference values for the Brazilian population, we used the median of the serum selenium level of the controls as the cut-off point. At 30 and 60 days of antituberculosis treatment, we repeated the biochemical tests, as well as collecting sputum for smear microscopy and culture from the patients. Results: The mean age of the patients was 38.4 ± 11.4 years. Of the 35 patients, 25 (71%) described themselves as alcoholic; 20 (57.0%) were smokers; and 21 (60.0%) and 32 (91.4%) presented with muscle mass depletion as determined by measuring the triceps skinfold thickness and arm muscle area, respectively. Of 24 patients, 12 (39.2%) were classified as moderately or severely emaciated, and 15 (62.5%) had lost > 10% of their body weight by six months before diagnosis. At baseline, the tuberculosis group had lower serum selenium levels than did the control group. The conversion of bacteriological tests was associated with the CRP/albumin ratio and serum selenium levels 60 days after treatment initiation. Conclusions: Higher serum selenium levels after 60 days of treatment were associated with the conversion of bacteriological tests in pulmonary tuberculosis patients. PMID:25029650

    The aim of the meta-analysis described below was to investigate the correlation between serum levels of adiponectin (ADPN) and the pathogenesis of hepatocellular carcinoma (HCC). Relevant studies about serum ADPN levels and the pathogenesis of HCC were identified by searching electric databases and by manual search. The included studies were selected in strict accordance with the inclusion and exclusion criteria. Detailed criteria were described in "Materials and methods" section. Statistical analyses were conducted with the STATA 12.0 statistical software (StataCorp, College Station, TX, USA). A total of nine studies were incorporated into this meta-analysis after careful consideration, including 705 HCC patients and 1390 healthy controls. This meta-analysis demonstrated that the serum ADPN levels in HCC patients were significantly higher than those in healthy controls (standard mean difference (SMD) = 0.97, 95% confidence intervals (CI) = 0.02∼1.93, P < 0.05). The result of subgroup analysis by ethnicity revealed that serum ADPN levels in Caucasians and Asians were both obviously higher than those in healthy controls (Caucasians: SMD = 0.51, 95% CI = 0.30∼0.73, P < 0.001; Asians: SMD = 0.49, 95% CI = 0.06∼0.91, P < 0.05), but in Africans, the differences between HCC patients and controls had no statistical significance (SMD = 2.64, 95% CI = -3.01∼8.30, P = 0.36). The evidence obtained by this meta-analysis suggests that serum ADPN levels are associated with the pathogenesis of HCC. Further conclusion might be that increased serum levels of ADPN can inhibit tumor growth and play a protective role in the development of HCC. PMID:25492487

    Introduction Basal cell carcinoma (BCC) is an immunogenic neoplasm and the imbalance in Th1/Th2 cytokines expression seems to play the major role in pathogenesis and clinical behaviour of the tumour. Aim To investigate the association of soluble interleukin 2α receptor (sIL-2Rα) and interleukin-2 (IL-2) serum concentrations with BCC. Material and methods The study involved 110 individuals with BCC and 60 healthy age- and sex-matched volunteers. Serum levels of sIL-2Rα and IL-2 were measured using ELISA test. Results We found significantly (p = 0.027) increased sIL-2Rα serum levels in BCC patients, in comparison to healthy controls. Statistically (p = 0.04) higher sIL-2Rα levels were observed in patients with more advanced tumours. Serum levels of sIL-2Rα showed a significant linear (r = 0.24, p = 0.018) correlation with tumour size. The average IL-2 serum levels in BCC patients were statistically (p = 0.039) decreased compared to controls. Significantly (p = 0.0454) lower median IL-2 levels were observed in patients with more advanced tumours. A negative correlation between sIL-2Rα and IL-2 serum concentrations was revealed (r = –0.22; p = 0.027). Conclusions Our results testify to the importance of the IL-2/sIL-2Rα signalling pathway in pathogenesis of BCC, suggesting that IL-2 and sIL-2Rα might be considered as potential markers of disease and targets for immunotherapy in BCC patients.

    A large body of evidence indicates alterations in brain regional cellular energy metabolism and blood flow in schizophrenia. Among the different molecules regulating blood flow, vascular endothelial growth factor (VEGF) is generally accepted as the major factor involved in the process of angiogenesis. In the present study, we examined whether peripheral VEGF levels correlate with changes in the prefrontal cortex (PFC) volume in patients with schizophrenia and in healthy controls. Whole-blood samples were obtained from 96 people with schizophrenia or schizoaffective disorder and 83 healthy controls. Serum VEGF protein levels were analyzed by enzyme-linked immunosorbent assay, whereas quantitative PCR was performed to measure interleukin-6 (IL-6, a pro-inflammatory marker implicated in schizophrenia) mRNA levels in the blood samples. Structural magnetic resonance imaging scans were obtained using a 3T Achieva scanner on a subset of 59 people with schizophrenia or schizoaffective disorder and 65 healthy controls, and prefrontal volumes were obtained using FreeSurfer software. As compared with healthy controls, individuals with schizophrenia had a significant increase in log-transformed mean serum VEGF levels (t(177)=2.9, P=0.005). A significant inverse correlation (r=-0.40, P=0.002) between serum VEGF and total frontal pole volume was found in patients with schizophrenia/schizoaffective disorder. Moreover, we observed a significant positive association (r=0.24, P=0.03) between serum VEGF and IL-6 mRNA levels in patients with schizophrenia. These findings suggest an association between serum VEGF and inflammation, and that serum VEGF levels are related to structural abnormalities in the PFC of people with schizophrenia. PMID:26169975

    Osteogenesis imperfecta (OI) is a group of genetic disorders characterized by bone fragility and deformity. OI type VI is unique owing to the mineralization defects observed in patient biopsies. Furthermore, it has been reported to respond less well to standard therapy with bisphosphonates [1]. Others and we have previously identified SERPINF1 mutations in patients with OI type VI. SERPINF1 encodes pigment epithelium derived factor (PEDF), a secreted collagen-binding glycoprotein that is absent in the sera of patients with OI type VI. Serpinf1 null mice show increased osteoid and decreased bone mass, and thus recapitulate the OI type VI phenotype. We tested whether restoration of circulating PEDF in the blood could correct the phenotype of OI type VI in the context of protein replacement. To do so, we utilized a helper-dependent adenoviral vector (HDAd) to express human SERPINF1 in the mouse liver and assessed whether PEDF secreted from the liver was able to rescue the bone phenotype observed in Serpinf1(-/-) mice. We confirmed that expression of SERPINF1 in the liver restored the serum level of PEDF. We also demonstrated that PEDF secreted from the liver was biologically active by showing the expected metabolic effects of increased adiposity and impaired glucose tolerance in Serpinf1(-/-) mice. Interestingly, overexpression of PEDF in vitro increased mineralization with a concomitant increase in the expression of bone gamma-carboxyglutamate protein, alkaline phosphatase and collagen, type I, alpha I, but the increased serum PEDF level did not improve the bone phenotype of Serpinf1(-/-) mice. These results suggest that PEDF may function in a context-dependent and paracrine fashion in bone homeostasis. PMID:26693895

    Many in situ XAFS studies have shown that zinc incorporated in layered minerals is a major form of zinc in Zn-contaminated soils. Quantitative information on the local structural environment(s) and ordering of Zn in these minerals is required to better understand its behavior in soils. In this study, EXAFS spectroscopy was used to assess the structural environment of zinc incorporated at trace levels (40 ppm to 4,000 ppm) within the octahedral sheets of various natural and synthetic layered minerals. Results indicate that EXAFS data analyzed using ab initio FEFF calculations (FEFF 8.10) can unambiguously distinguish between zinc incorporation within the octahedral sheet of dioctahedral versus trioctahedral layered minerals and can determine the distribution (random or ordered) of zinc cations within the octahedral sheets of these minerals.

    In this paper we demonstrate that patients treated with chemotherapy and/or hematopoietic stem cell transplantation (HSCT) have highly significant reduced serum ascorbic acid (AA) levels compared to healthy controls. We recently observed in in vitro experiments that growth of both T and NK cells from hematopoietic stem cells is positively influenced by AA. It might be of clinical relevance to study the function and recovery of immune cells after intensive treatment, its correlation to AA serum levels and the possible effect of AA supplementation.

    Context: The key role of serum estradiol (E2) for bone health in men is well established. The effect of serum sex steroids on bone microstructure, measured by high-resolution peripheral quantitative computed tomography, remains unknown in elderly men. Objective: The objective of the study was to examine the associations between serum sex steroids and bone microstructural parameters in older men. Methods: Trabecular and cortical bone microstructure at the tibia was measured by high-resolution peripheral quantitative computed tomography in 440 men (mean 80 y of age) participating in the population-based Osteoporotic Fractures in Men Sweden cohort. Serum levels of E2 and T were analyzed with mass spectrometry and free E2 and free T levels were calculated using law-of-mass-action equations. Results: Age-adjusted models demonstrated that E2 and free E2 but not T or free T associated significantly inversely with cortical porosity. The associations between E2 and free E2 and cortical porosity remained significant after further adjustment for height, weight, physical activity, calcium intake, and smoking. Models including both serum E2 and T demonstrated that E2 (standardized β = −.12, P < .05) but not T associated independently with cortical porosity. A similar independent association was found for free E2 (standardized β = −.12, P < .05) but not free T. Free E2 associated significantly with trabecular bone volume fraction in the age-adjusted models, but this association did not remain significant after further adjustment. Conclusions: Serum E2 levels associated inversely with cortical porosity in 80-year-old men. We propose that low serum E2 may reduce cortical bone strength, at least partly, by increasing cortical porosity and thereby increase fracture risk in older men. PMID:24694340

    Serum enzymes were studied in 163 apparently healthy goats from three indigenous goat breeds of Ethiopia. The effect of breed, age, sex and season on alanine aminotransferase (ALT) / glutamic pyruvic transaminase (GPT), aspartate aminotransferase (AST) / glutamic oxalacetic transaminases (GOT), alkaline phosphatase (ALP) and acid phosphatase (AcP) levels was assessed. The mean serum enzymes levels of the indigenous Arsi-Bale, Central Highland and Long-eared Somali goat breeds ranged from 14.0-20.2 iu L(-1) for ALT/GPT, from 43.2-49.3 iu L(-1) for AST/GOT, from 83.7-98.8 iu L(-1) for ALP, and from 2.99-4.23 iu L(-1) for AcP, were within the normal range for goats elsewhere. Breed had significant influence on AST/GOT values. Sex had significant effect on ALT/GPT for Arsi-Bale goats with higher values in males than females. Age was significant on all serum enzymes studied in the Arsi-Bale goats and on ALP in the Central Highland goats. Season had significant influence on all serum enzymes except for ALT/GPT in the Arsi-Bale goats. The serum enzyme levels of these indigenous goat breeds can be used as normal reference values for Ethiopian goat breeds adapted to similar agro-ecology and production system. PMID:18975131

    Objectives. The study was aimed to assess the association between low maternal serum magnesium levels and preterm labour. Methods. It is a cross-sectional case-control study in which eligible participants were pregnant women admitted in labour within the labour ward complex of a Lagos tertiary hospital. Relevant data were extracted from the case records of these women and blood samples were obtained from all participants and serum magnesium levels measured. Results. The study showed that 36% of the study patients had varying degrees of hypomagnesaemia. The relative risk indicates that preterm labour is 1.83 times higher among the patients with low serum magnesium (less than 1.6 mg/dL). The mean difference in serum magnesium levels in both groups was statistically significant (P<0.05). Conclusion. We can infer that low serum magnesium (hypomagnesaemia) is associated with preterm onset of labour. We can, also from this finding, formulate a proposition that would help in preventing preterm labour and birth with the use of prophylactic oral magnesium supplementation among patients with higher risk for development of preterm labour.

    Resistin is an adipocytokine that is associated with inflammation, coronary artery disease, and other types of cardiovascular disease among patients with normal kidney function. However, little is known about the association of resistin with outcomes in kidney transplant recipients. We collected socio-demographic and clinical parameters, medical and transplant history, and laboratory data from 988 prevalent kidney transplant recipients enrolled in the Malnutrition-Inflammation in Transplant-Hungary Study (MINIT-HU study). Serum resistin levels were measured at baseline. Associations between serum resistin level and death with a functioning graft over a 6-year follow-up period were examined in unadjusted and adjusted models. The mean±SD age of the study population was 51 ± 13 years, among whom 57% were men and 21% were diabetics. Median serum resistin concentrations were significantly higher in patients who died with a functioning graft as compared to those who did not die during the follow-up period (median [IQR]: 22[15-26] vs. 19[14-22] ng/ml, respectively; P < 0.001). Higher serum resistin level was associated with higher mortality risk in both unadjusted and fully adjusted models: HRs (95% CI): 1.33(1.16-1.54) and 1.21(1.01-1.46), respectively. In prevalent kidney transplant recipients, serum resistin was an independent predictor of death with a functioning graft. PMID:26639524

    In observational studies, serum urate concentrations associate with bone mineral density (BMD) and reduced risk of fractures. Thiazide diuretics slow the bone loss in healthy older adults, are associated with reduced incidence of fracture and also increase serum urate. We hypothesized that changes in serum urate are associated with changes in BMD during treatment with thiazide diuretics. We analysed data from a double-blind randomized controlled trial of hydrochlorothiazide (50 mg per day) and placebo in normal post-menopausal women. The relationship between change in serum urate and change in BMD after 2 years of treatment was examined using Spearman correlation and multiple linear regression models. Total body BMD increased in the hydrochlorothiazide group by 0.52 % and reduced in the placebo group by 0.29 % over 2 years (between group difference P = 0.0034). Serum urate increased in the hydrochlorothiazide group by 0.038 mmol/L and reduced in the placebo group by 0.004 mmol/L (between group difference P < 0.0001). At Year 2, there was a positive relationship between the change in serum urate and change in total body BMD for entire study population (r = 0.32, P = 0.0002) and for the hydrochlorothiazide group (r = 0.29, P = 0.023). The association between change in serum urate and change in total body BMD persisted after adjusting for treatment allocation, and change in weight, serum calcium, urinary calcium and serum creatinine (P change in serum urate = 0.043). These data raise the possibility that the effects of hydrochlorothiazide on BMD may be mediated, in part, by changes in serum urate concentrations. PMID:26713333

    Background To explore the relationship between preoperative serum CA19-9 and CEA levels and prognosis of pancreatic cancer (PC). Methods The clinicopathological data of 128 patients with pancreatic adenocarcinoma who were treated in our center between January 2012 and December 2013 were retrospectively analyzed. The relationships between serum CA19-9 and CEA levels and survival were analyzed using Kaplan-Meier method, log-rank test, and Cox regression analysis. The cut-off values for serum CA19-9 and CEA levels were 39 U/mL and 4.7 ng/mL, respectively. Results Among these 128 patients, the mean age was 62 years, and median survival was 12.2 days. The positive rate of CA19-9 and CEA was 78.1% and 37.5%, respectively. Patients with increased CA19-9 or CEA level suffered a poorer prognosis than those with normal CA19-9 or CEA level (CA19-9: P=0.027; CEA: P=0.036). Cox logistic analysis revealed that lymphatic metastasis, CA19-9 >39 U/mL, and CEA >4.7 ng/mL were independent prognostic factors in patients with pancreatic carcinoma. Conclusions Preoperative serum CA19-9 and CEA level are closely related with survival time in PC patients and therefore may be used for evaluating the prognosis for PC. PMID:26734638

    Background The correlation between aortic functions and paraoxonase levels has been previously demonstrated by several earlier studies. In this study, we aimed to investigate the correlation between serum paraoxonase levels and aortic functions among patients with chronic kidney disease. Methods Our study enrolled 46 chronic kidney disease patients and 45 healthy controls. From these patients, serum cholesterol, creatinine, hemoglobin, and paraoxonase-1 levels were analyzed. Results Paraoxonase-1 levels were significantly lower in patients with chronic kidney disease compared to the controls (p < 0.001). Additionally, the extent of aortic stiffness index (%) was significantly higher in chronic kidney disease patients, but aortic strain and aortic distensibility were significantly higher in healthy controls (p < 0.001, p < 0.001, and p < 0.001, respectively). We further found that paraoxonase-1 levels were correlated with aortic stiffness index, aortic strain, and aortic distensibility (p < 0.001, p < 0.001, and p < 0.001, respectively). Conclusions Our study demonstrated that serum paraoxonase-1 levels were significantly correlated with impaired aortic functions. The results of this study highlight the impact of serum paraoxonase-1 activity on atherosclerosis and cardiovascular adverse events. PMID:27122934

    An unknown fraction of the genome participates in the metabolism of sterols and vitamin D, two classes of lipids with diverse physiological and pathophysiological roles. Here, we used mass spectrometry to measure the abundance of >60 sterol and vitamin D derivatives in 3,230 serum samples from a well-phenotyped patient population. Twenty-nine of these lipids were detected in a majority of samples at levels that varied over thousands of fold in different individuals. Pairwise correlations between sterol and vitamin D levels revealed evidence for shared metabolic pathways, additional substrates for known enzymes, and transcriptional regulatory networks. Serum levels of multiple sterols and vitamin D metabolites varied significantly by sex, ethnicity, and age. A genome-wide association study identified 16 loci that were associated with levels of 19 sterols and 25-hydroxylated derivatives of vitamin D (P < 10−7). Resequencing, expression analysis, and biochemical experiments focused on one such locus (CYP39A1), revealed multiple loss-of-function alleles with additive effects on serum levels of the oxysterol, 24S-hydroxycholesterol, a substrate of the encoded enzyme. Body mass index, serum lipid levels, and hematocrit were strong phenotypic correlates of interindividual variation in multiple sterols and vitamin D metabolites. We conclude that correlating population-based analytical measurements with genotype and phenotype provides productive insight into human intermediary metabolism. PMID:25201972

    Abstract Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated. Patients who underwent coronary artery bypass or valve surgery at Yonsei University Health System from January 2013 to December 2014 were enrolled. The patients were divided into 3 groups based on preoperative serum bicarbonate levels, which represented group 1 (below normal levels) <23 mEq/L; group 2 (normal levels) 23 to 24 mEq/L; and group 3 (elevated levels) >24 mEq/L. The primary outcome was the predicated incidence of AKI 48 hours after cardiac surgery. AKI was defined according to Acute Kidney Injury Network criteria. Among 875 patients, 228 (26.1%) developed AKI within 48 hours after cardiac surgery. The incidence of AKI was higher in group 1 (40.9%) than in group 2 (26.5%) and group 3 (19.5%) (P < 0.001). In addition, the duration of postoperative stay in a hospital intensive care unit (ICU) was longer for AKI patients and for those in the low-preoperative-serum-bicarbonate-level groups. A multivariate logistic regression analysis showed that low preoperative serum bicarbonate levels were significantly associated with AKI even after adjustment for age, sex, hypertension, diabetes mellitus, operation type, preoperative hemoglobin, and estimated glomerular filtration rate. In conclusion, low serum bicarbonate levels were associated with higher incidence of AKI and prolonged ICU stay. Further studies are needed to clarify whether strict correction of bicarbonate levels close to normal limits may have a

    We investigated the serum levels of the phosphorylated form of the high molecular weight neurofilament subunit (pNF-H) in patients with cervical compressive myelopathy. pNF-H is becoming increasingly recognized as a biomarker for axonal injury, however, it remains unclear whether serum pNF-H is elevated in chronic spinal cord compression. We examined 26 patients who underwent surgery for cervical compressive myelopathy. Peripheral blood samples were obtained both preoperatively and 1 week after surgery to evaluate the serum pNF-H levels using an enzyme-linked immunosorbent assay. A history of recent aggravation of myelopathy was also investigated. Of the 26 myelopathy patients, the preoperative serum pNF-H level was negative in 20 patients and moderately elevated in six. Patients who were positive for pNF-H were more likely to have had a recent aggravation of myelopathy compared with the pNF-H negative patients (83 versus 25%; p=0.02). All patients who were positive for pNF-H before surgery remained positive after surgery. Two patients who became positive after surgery demonstrated a neurologic deterioration associated with the surgery. In conclusion, the serum pNF-H level was negative in the majority of patients with cervical compressive myelopathy. Our results suggest that an elevated serum level of pNF-H is associated with an acute worsening of myelopathy and that a positive conversion of pNF-H after surgery is a marker of perioperative neural damage.

    Through the treatment of anaemia in dialysis patients part of the iron ions remain free in the serum which is at the bacterias disposal for growth and the strengthening of their virulence. The linear relation of the increased serum iron level and tissue iron stores in the body and the infection incidence in dialysed patients has become more emphasised. The need of a clearly defined upper threshold of the serum iron concentration limit has been mentioned in scientific journals intensely, and consequently the demand for more precise professional instructions for anaemia treatment. For the purpose of participating in these professional and scientific discussions, we have observed the relation between the iron overload of the organism and complication incidence in 120 of our haemodialysis uremic patients, with special emphasis on infections. It has been established that the sepses incidence is much higher in patients with a serum ferritin concentration above 500 microg/L, than in those patients with a ferritin level lower than the mentioned value ( 2 = 7.857, p = 0.005). The incidence of vascular access infection is significantly higher in those patients with a serum ferritin level above 500 microg/L than in those patients with a ferritin level lower than the mentioned value (Chi2 = 23.186, p = 0.001). Furthermore, it has been determined that the incidence of total infection in patients is 3.8 episodes per 100 patients months, which is in accordance to the referral values of other authors. CONCLUSION--In the analysis of the achieved results, it has been determined that the infection incidence is significantly higher in dialysed patients with a serum iron level higher than 500 g/L, than in those patients with lower values.

    Hormonal dependency of canine mammary tumours (CMT) has been studied over the last few decades. However, studies assessing the prognostic and predictive potential of serum and/or tissue steroid hormone levels are still scarce in CMT. To the best of our knowledge, this is the first report relating serum and tissue levels of steroid hormones and prognosis in dogs. Serum and tumour tissue from 45 female dogs with spontaneous CMT were included in the study. Moreover, serum and normal mammary tissue from 13 healthy female dogs were also included as controls. Steroid hormones were determined by competitive enzyme immunoassay. Overall, levels of steroid hormones in serum and tissue homogenates were significantly different between malignant and benign mammary tumours (p < 0.01), except for progesterone (P4) serum levels that revealed no statistical differences between groups. In malignant tumours, oestrone sulphate (SO4E1), dehydroepiandrosterone (DHEA), androstenedione (A4), testosterone (T) and P4 elevated tissue concentrations were significantly associated with tumour relapse and/or distant metastasis during follow-up. A significant association was found between elevated tissue SO4E1 (p = 0.003), 17β-oestradiol (E2) (p = 0.036), DHEA (p = 0.022), A4 (p = 0.001) and P4 (p = 0.013) concentrations and shorter disease-free survival and overall survival in female dogs with malignant mammary tumours. The high levels of tissue steroids found in cases of poor prognosis open the possibility of additional new therapeutic approaches. Future clinical trials will be needed to clarify the usefulness of targeting steroid hormones in the treatment of this neoplastic disease. PMID:26332137

    Background: Both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. Little is known about the relations of serum uric acid (UA) level to regional arterial stiffness and wave reflection. The aim of the study was to investigate the gender-specific association of serum UA and indices of arterial function in a community-based investigation in China. Methods: Cross-sectional data from 2374 adults (mean age 58.24 years) who underwent routine laboratory tests, regional pulse wave velocity (PWV) and pulse wave analysis measurements were analyzed in a gender-specific manner. None of the participants had atherosclerotic cardiovascular disease, chronic renal failure, systemic inflammatory disease, gout, or were under treatment which would affect serum UA level. Results: Men had higher serum UA level than women. Subjects with hyperuricaemia had significantly higher carotid-ankle PWV in both genders (P< 0.05), and the carotid-femoral PWV (PWVc-f) was higher in women (P< 0.001) while the augmentation index was marginally lower in men (P = 0.049). Multiple regression analysis showed that serum UA was an independent determinant only for PWVc-f in women (β = 0.104, P = 0.027) when adjusted for atherogenic confounders. No other independent relationship was found between UA level and other surrogates of arterial stiffness. Conclusions: Serum UA levels are associated with alterations in systemic arterial stiffness that differ in men and women. Women might be more susceptible to large vascular damage associated with hyperuricaemia. PMID:23113222

    Coenzyme Q10 (CoQ10) exists in human tissue, and is indispensable to mitochondrial enzymes of respiration. CoQ was administered to children with preclinical muscular dystrophy, CoQ enzymology was emphasized, and serum creatine phosphokinase, CPK, (ATP:creatine N-phosphotransferase, EC 2.7.3.2) was repeatedly monitored. A 40-week treatment of an infant, 1-2 years of age, reduced serum CPK (P < 0.001; total CPK assays, 76). A 40-week treatment of a boy, 3-5 years of age, reduced serum CPK (P < 0.01); treatment through 80 weeks reduced CPK (P < 0.001; total CPK assays, 118). This response of preclinical dystrophy to CoQ implies a deficiency of CoQ in skeletal muscle that was actually found previously by assay of the activity of the succinate dehydrogenase:coenzyme Q10 reductase of the rectus abdominis. The relationships among a CoQ deficiency in muscle, serum CPK, and use of CPK in muscle are uncertain; however, restoration of CoQ enzyme activity in muscle by oral administration of CoQ could lead to increased use of CPK in muscle to form phosphocreatine from creatine and ATP, with a corresponding decrease in serum levels of CPK. The great excess of CPK in serum comes from deteriorating muscle in which CPK is below normal. PMID:4525474

    Irisin is an exercise-regulated myokine inducing browning of white adipose tissue and has gained interest as a potential new strategy to combat obesity and its associated disorders, such as type 2 diabetes mellitus (T2DM). The aim of this study is to evaluate the circulating serum irisin levels in obesity and T2DM and also to elucidate possible relationships between serum irisin levels with anthropometric and metabolic parameters of obesity and T2DM. One hundred fifty newly diagnosed T2DM patients as well as 150 nondiabetic control subjects were enrolled in this study. Nondiabetic controls were then stratified according to their body mass index (BMI) into three subgroups; lean, overweight, and obese. Serum irisin levels were evaluated by enzyme-linked immunosorbent assay. Serum irisin levels were significantly decreased in T2DM patients compared with nondiabetic controls. Obese nondiabetic controls had significantly higher serum irisin levels compared with lean nondiabetic controls. In both nondiabetic controls and T2DM patients, serum irisin was significantly positively correlated with BMI (r = 0.985, P < 0.001 and r = 0.218, P = 0.007, respectively), fat mass (r = 0.959, P < 0.001 and r = 0.202, P = 0.013, respectively), fat-free mass (r = 0.606, P < 0.001 and r = 0.194, P = 0.017, respectively), fat-free mass index (r = 0.820, P < 0.001 and r = 0.179, P = 0.028, respectively), waist-to-hip ratio (r = 0.880, P < 0.001 and r = 0.194, P = 0.017, respectively), fasting insulin (r = 0.989, P < 0.001 and r = 0.207, P = 0.011, respectively), and HOMA-IR (r = 0.989, P < 0.001 and r = 0.185, P = 0.023, respectively), whereas; significantly negatively correlated with insulin sensitivity (r = -0.992, P < 0.001 and r = -0.187, P = 0.022, respectively). In this study, we demonstrated that circulating serum irisin levels were increased in obese nondiabetic subjects, while decreased in T2DM patients. Moreover, serum irisin levels were correlated

    In high-dose intake of phenytoin, which is used frequently to treatepilepsy, nystagmus, diplopia, nausea-vomiting, lethargy, confusion, seizure, and coma can be observed. In recent studies on phenytoin intoxication, in which seizure and coma were observed in drug levels greater than 50 ug/mL. The serum phenytoin level of apatient, who consumed approximately 100 pcs of 100 mg phenytoin tablets in an effort to commit suicide, and who had no pathological finding in her neurologic examination, was 124 ug/mL. High drug level and the absence of toxic effect (or the absence of toxic effect correlated with the drug level) indicates that cytochrome P450 is functioning, but there can be a mutation in the MDR1 gene. In our case study, we report on phenytoin intoxication in a patient having a high level of phenytoin but no symptoms correlated with serum drug level, as supported by the findings in the literature.

    High homocysteine serum level has been regarded as one of the important factors that influence the development of schizophrenia. Genetic variations of methylenetetrahydrofolate reductase, which is a main enzyme reducing homocysteine level, are reported in schizophrenic patients. We measured the serum level of homocysteine/folate and methylenetetrahydrofolate reductase C677T/A1298C gene polymorphism in 235 patients with schizophrenia. Plasma homocysteine levels were higher and folate levels were lower in patients than in comparison subjects. Variations of C677T were more frequent in patients than in comparison subjects. Patients with the 677TT genotype showed higher homocysteine levels than patients with the CC and CT genotypes. These findings suggest that folate supplement may be beneficial to some schizophrenic patients with homocysteinemia due to the genetic defect of methylenetetrahydrofolate reductase. PMID:16641680

    Fossil fuels, especially coal, can support the energy demands of the world for centuries to come, if the environmental problems associated with CO{sub 2} emissions can be overcome. Permanent and safe methods for CO{sub 2} capture and disposal/storage need to be developed. Mineralization of stationary-source CO{sub 2} emissions as carbonates can provide such safe capture and long-term sequestration. Mg-rich lamellar-hydroxide based minerals (e.g., brucite and serpentine) offer a class of widely available, low-cost materials, with intriguing mineral carbonation potential. Carbonation of such materials inherently involves dehydroxylation, which can disrupt the material down to the atomic level. As such, controlled dehydroxylation before and/or during carbonation may provide an important parameter for enhancing carbonation reaction processes. Mg(OH){sub 2} was chosen as the model material for investigating lamellar hydroxide mineral dehydroxylation/carbonation mechanisms due to (i) its structural and chemical simplicity, (ii) interest in Mg(OH){sub 2} gas-solid carbonation as a potentially cost-effective CO{sub 2} mineral sequestration process component, and (iii) its structural and chemical similarity to other lamellar-hydroxide-based minerals (e.g., serpentine-based minerals) whose carbonation reaction processes are being explored due to their low-cost CO{sub 2} sequestration potential. Fundamental understanding of the mechanisms that govern dehydroxylation/carbonation processes is essential for cost optimization of any lamellar-hydroxide-based mineral carbonation sequestration process.

    This study was undertaken to elucidate the effect of ammonia-generating diet on serum and follicular fluid ammonia and urea levels, serum oestrogen and progesterone concentrations and granulosa cell growth and secretion parameters in ewes (Ovis aries). Ewes were fed with 14% CP diet (control) or ammonia-generating diet or ammonia-generating diet plus soluble sugar. The serum and follicular fluid ammonia and urea level, serum oestrogen and progesterone levels and granulosa cell (obtained from ovaries of slaughtered ewes) growth parameters and secretory activities were estimated. Ammonia-generating diet (high-protein diet) increased the serum ammonia and urea concentration. Supplementation of soluble sugar significantly reduced the ammonia concentration in serum with comparable levels as in control group; however, the urea level in the same group was higher than that observed in control group. Supplementation of soluble sugar significantly reduced the follicular fluid ammonia concentration; however, the level was significantly higher compared to control group. Supplementation of soluble sugar brought down the follicular fluid urea level comparable to that observed in control group. Oestrogen and progesterone levels remained unchanged in ewes fed with different types of diet. Oestrogen and progesterone secretion were significantly lowered from granulosa cells recovered from ewes fed with high ammonia-generating diet. Low metabolic activity and high incidence of apoptosis were observed in granulosa cells obtained from ovaries of ewes fed with ammonia-generating diet. PMID:26211538

    The available data on potential alterations in serum melatonin (MLT) levels during a human lifetime are fragmentary and inconsistent. We, therefore, measured day- and nighttime serum MLT concentrations in 367 subjects (210 males and 157 females), aged 3 days to 90 yr. Blood samples were collected between 0730 and 1000 h and between 2300 and 0100 h. Serum MLT levels were measured by RIA. The mean nighttime serum MLT concentration was low during the first 6 months of life, i.e. 27.3 +/- 5.4 (+/- SE) pg/mL (0.12 +/- 0.02 nmol/L). It then increased to a peak value at 1-3 yr of age [329.5 +/- 42.0 pg/mL; (1.43 +/- 0.18 nmol/L)], and it was considerably lower [62.5 +/- 9.0 pg/mL; (0.27 +/- 0.04 nmol/L)] in individuals aged 15-20 yr. During the following decades serum MLT declined moderately until old age (70-90 yr of age), i.e. 29.2 +/- 6.1 pg/mL (0.13 +/- 0.03 nmol/L). This biphasic MLT decline follows 2 exponential functions with different slopes (from age 1-20 yr: r = -0.56; P less than 0.001; y = 278.7 X e -0.09x; from age 20-90 yr: r = -0.44; P less than 0.001; y = 84.8 X e -0.017x). The decrease in nocturnal serum MLT in children and adolescents (1-20 yr) correlated with the increase in body weight (r = -0.54; P less than 0.001) and body surface area (r = -0.71; P less than 0.001). At a later age (20-90 yr) there was no correlation among these variables. Daytime serum MLT levels were low and no age-related alterations were found. This study revealed major age-related alterations in nocturnal serum MLT levels. The negative correlation between serum MLT and body weight in childhood and adolescence is evidence that expansion of body size is responsible for the huge MLT decrease during that period. The moderate decline at older ages must derive from other factors. PMID:3350912

This study examined whether serum matrix metalloproteinase‐3 (MMP‐3) levels correlate with disease activity in MS. Methods Serum MMP‐3 levels in 47 consecutive patients with relapsing‐remitting MS were measured by immunoassay every 4 weeks over a 15 month period. Results During the study period, 48 clinical relapses occurred. Serum MMP‐3 levels within 1 month of relapse were significantly higher than during the remission phase. Sequential analysis showed that serum MMP‐3 levels had increased transiently at the time of clinical relapse but returned to the normal range within a month. Conclusions Circulatory MMP‐3 levels are correlated with disease activity in relapsing‐remitting MS. This may contribute to the breakdown of the blood‐brain barrier at the time of relapse.

    Background: Endometriosis is known as one of the most common disease in women of reproductive age. Due to important role of vascular endothelial growth factor (VEGF) in neo-vascularization for the implantation of endometrial cell, and also presence of different studies reported VEGF level in the serum and peritoneal fluid (PF) in endometriosis patients, this study was designed to determine the serum and PF levels of VEGF in endometriosis patients, and to compare with normal subjects. Materials and Methods: In this descriptive study, 179 women subjected to laparoscopy for the evaluation of infertility or pelvic pain were allocated into the following two groups: group I: different types of endometriosis patients (n=90) and group II: non-endometriosis patients (n=89). The PF from pelvis and venous blood samples were obtained. The VEGF concentration of the serum and PF were measured using enzyme immunoassay kit and were compared using t test. Results: The level of VEGF in serum was significantly less than that in PF in both groups (p=0.00). However, endometriosis patients had significantly higher level of VEGF in peritoneal fluid than non-endometriosis patients (p=0.043). Conclusion: According to our findings, endometriosis is not associated with change in the level of circulating VEGF. PMID:24520470

    [Purpose] Sclerostin is mechanosensitive protein that is produced exclusively by osteocytes. It was reported that the plasma sclerostin level increases in the 10th minute after the application of Whole-Body Vibration. The aim of this study was to determine whether single extremity-vibration induces any change in the serum sclerostin level. [Subjects and Methods] Eight healthy young-adult volunteers were recruited for this pilot study. The participants sat on a chair with their left hip and knee joints flexed at 90 degrees. The lower leg was exposed to vibration: 40 Hz, 4 mm, 60 s. Blood samples were collected before and after the vibration. The serum sclerostin levels were blindly measured in dual-controlled blood samples. [Results] The serum sclerostin level before vibration was 328.2±589.9 pg/ml, and it showed no significant change after vibration. [Conclusion] Unlike Whole-Body Vibration, Single-Extremity Vibration did not affect the serum sclerostin level significantly. This finding can be explained by the limited bone volume exposed to vibration. Bone volume exposed to vibration is less during Single-Extremity Vibration than during Whole-Body Vibration.

    Serum levels of carboxyterminal propeptide of type I procollagen (PICP) and aminoterminal propeptide of type III procollagen (PIIINP) can be used as markers of bone formation and the evaluation of children with growth disorders. We measured the serum levels of these collagens with radioimmunoassay in 24 children aged between 4 and 14 years with chronic renal failure (CRF; n = 12 dialysis, n = 12 nondialysis) and 12 age-matched healthy controls, to find out whether these parameters have a prognostic or therapeutic value in monitoring the growth retardation in CRF. Mean serum PIIINP levels in the dialysis patients were higher than in the control group; the difference between the groups was statistically significant (p < 0.05). It seemed that the pubertal stage of the patients did not affect the levels of PICP and PIIINP. There was no significant correlation between PICP and PIIINP in any patients. Neither PICP nor PIIINP correlated with the height z-score or bone age. It was concluded that the increased serum PIIINP levels in renal patients might be accepted as a poor prognostic factor leading to progressive renal failure and end-stage renal disease. Further investigations into the effects of these collagens on growth failure associated with CRF are needed. PMID:8684525

    The aim of this study was to analyze the serum levels of activin A in hyperthyroid patients with Graves' disease. Serum activin A and FSH levels were measured in a total of 93 females (64 regularly cycling and 29 post-menopausal). Of these, 20 were hyperthyroid patients with Graves disease, 33 were euthyroid goitrous patients (20 had autoimmune thyroiditis AT and 13 only had goiter) representing the internal control group and 40 were healthy subjects representing the external control group. Serum levels of activin A were higher in goitrous patients with AT than in control subjects (p=0.0388). Activin A levels were almost doubled in the cycling and in post-menopausal hyperthyroid women (0.91+/-0.21 vs 0.43+/-0.07 microg/l; p<0.0001 and 0.92+/-0.22 vs 0.48+/-0.24 microg/l; p=0.0001, respectively). In 10 cycling hyperthyroid patients, studied even after methimazole treatment, that increase was substantially reversed, once euthyroidism was attained (p=0.002). These findings indicate that thyroid function and autoimmune processes significantly affect serum levels of activin A in patients with Graves' disease. PMID:12553556

    Aims Serum cystatin C (CysC) has recently been shown to be associated with the incidence of type 2 diabetes mellitus (T2DM) and progression to the pre-diabetic state. The aim of this study was to explore the relationship between serum CysC and the risk of gestational diabetes mellitus (GDM) in Chinese pregnant women. Methods This cross-sectional study consisted of 400 pregnant women including111 with GDM and 289 with normal glucose tolerance at 24–28 weeks of gestation. The subjects were further divided into four groups according to the CysC quartiles, and their clinical characteristics were compared. The serum CysC concentration was measured using immunoturbidimetry and the degree of insulin resistance was assessed by the homeostasis model assessment of insulin resistance (HOMA-IR). Results Serum CysC levels were significantly higher in pregnant women with GDM than in the healthy pregnant women[1.0(0.8–1.8) vs 0.7(0.6–1.0), P<0.01). The Spearman’s correlation analysis showed that serum CysC was positively associated with HOMA-IR(r = 0.118, P<0.05) and the occurrence of GDM(r = 0.348, P<0.01). The pregnant women were divided into quartiles according to their serum CysC concentrations. Compared to the first quartile, pregnant women in Q2 (OR, 2.441; P = 0.025), Q3 (OR, 3.383; P = 0.001) and Q4 (OR, 5.516; P<0.001) had higher risk of GDM after adjusted for age, BMI, HbA1c and HOMA-IR. Further, with a rise in the serum CysC, there was an increasing trend in the HOMA-IR levels (P<0.05). A binary logistic regression analysis after adjusting for other confounding variables revealed a significant and independent association between serum CysC and GDM [OR = 14.269; 95% confidence interval, 4.977–40.908, P<0.01].The receiver operating characteristic curve analysis revealed that the optimal cutoff point for serum CysC to indicate GDM was 0.95mg/L. Conclusions Serum CysC is significantly and independently associated with insulin resistance and GDM. It may be a

    Background Expression and activity of the fibroblast growth factor (FGF) 21 hormone-like protein are associated with development of several metabolic disorders. This study was designed to investigate whether serum FGF21 level was also associated with the metabolic syndrome-related cardiovascular disease, atherosclerosis, and its clinical features in a Chinese cohort. Methods Two-hundred-and-fifty-three subjects visiting the Cardiology Department (Sixth People's Hospital affiliated to Shanghai JiaoTong University) were examined by coronary arteriography (to diagnose coronary artery disease (CAD)) and hepatic ultrasonography (to diagnose non-alcoholic fatty liver disease (NAFLD)). Serum FGF21 level was measured by enzyme-linked immunosorbent assay and analyzed for correlation to subject and clinical characteristics. The independent factors of CAD were determined by multivariate logistic regression analysis. Results Subjects with NAFLD showed significantly higher serum FGF21 than those without NAFLD (388.0 pg/mL (253.0-655.4) vs. 273.3 pg/mL (164.9-383.7), P < 0.01). Subjects with CAD showed significantly higher serum FGF21, regardless of NAFLD diagnosis (P < 0.05). Serum FGF21 level significantly elevated with the increasing number of metabolic disorders (P for trend < 0.01). After adjustment of age, sex, and BMI, FGF21 was positively correlated with total cholesterol (P < 0.05) and triglyceride (P < 0.01). FGF21 was identified as an independent factor of CAD (odds ratio = 2.984, 95% confidence interval: 1.014-8.786, P < 0.05). Conclusions Increased level of serum FGF21 is associated with NAFLD, metabolic disorders and CAD. PMID:23981342

    Inadequate vitamin D status is highly prevalent in the Korean population, especially among young adults. Nonetheless, correlates of suboptimal vitamin D levels in young adults are not well defined. This study aimed to investigate potentially modifiable determinants of vitamin D levels in young adults in Korea. This cross-sectional study was based on health check-up data from 3,450 healthy male and female university students aged 18-29 yr in Seoul between April and May 2013. Serum 25-hydroxyvitamin D [25(OH)D] levels were determined using chemiluminescent immunoassay. Anthropometric data were measured, and lifestyle, dietary, and sociodemographic factors were obtained through self-administered questionnaires. General linear regression was used to assess correlates of serum 25(OH)D levels. The mean serum 25(OH)D level was 11.1 ng/mL, and the prevalence of 25(OH)D levels less than 10 ng/mL was 44.7% (39.5% in men, 50.2% in women). In a final multivariable model, significant positive correlates of serum 25(OH)D were older age, male sex, increased physical activity, sunlight exposure ≥ 30 min/day, eating breakfast regularly, consumption of dairy and fatty fish, and use of vitamin D-containing supplements. In contrast, significant inverse correlates were obesity (body mass index, BMI ≥ 25 kg/m(2)) or underweight (BMI < 18.5 kg/m(2)), abdominal obesity, increased sedentary time, and frequent consumption of instant noodles and sugar-sweetened beverages. In conclusion, many modifiable lifestyle and dietary factors were associated with low serum 25(OH)D levels in Korean young adults. Further studies on potential mechanisms of the correlates and optimal strategies to improve vitamin D status in this vulnerable subpopulation are warranted. PMID:26240489

    Background Chronic obstructive pulmonary disease (COPD) is the only cause of mortality and morbidity with an increasing incidence. Adiponectin has recently gained the spotlight for its possible association with COPD or its exacerbation. This study evaluated the association of serum and alveolar adiponectin levels with COPD-related variables. Materials and Methods This analytical cross-sectional study was carried out on 45 COPD patients. Number of cigarettes smoked (packs), years of smoking, number of disease exacerbations per year and BMI were all recorded. Patients underwent spirometry and their disease severity was determined based on BODE index. Venous blood sample was obtained to measure the adiponectin serum level, ESR and CRP. Bronchoscopy and BAL were performed as well and alveolar secretions were collected to assess the alveolar fluid level of adiponectin. Result The mean serum level of adiponectin in COPD patients was significantly higher than the upper limit of normal range in healthy individuals (P = 0.000). Level of alveolar adiponectin in smoker patients was significantly higher than non-smokers (P = 0.043) but serum adiponectin was not significantly different between them. Serum adiponectin level had a significant reverse correlation with BMI and a direct correlation with number of exacerbations per year and CRP. Level of alveolar adiponectin had a direct association with number of exacerbations per year and number of smoked cigarettes. Conclusion Based on the obtained results, smoking cessation is very important in COPD and more emphasis should be placed on patient's weight control especially those with low BMI as well as rehabilitation programs for these patients.

    Background. Iron deposition in the body can damage the endocrine glands of patients with β-thalassaemia major (β-TM). Leptin plays a key role in the regulation of appetite, body fat mass, and endocrine function. Objectives. This study aimed to evaluate the relationship between serum leptin and growth and pubertal development in patients with β-TM, as well as whether serum leptin can predict growth retardation and delayed puberty in these patients. Methods. Fifty β-TM patients (aged 8–20 years) and 75 age-matched healthy controls were recruited. Anthropometric data and sexual maturity ratings were assessed. Serum leptin was measured by ELISA. Results. Serum leptin levels were significantly lower in patients with β-TM than in healthy individuals (P < 0.001). Leptin levels were also significantly reduced in female patients with short stature (P < 0.002) and in patients who displayed delayed puberty (P = 0.032) compared to those with normal stature who had reached puberty. The sensitivity of leptin for predicting short stature and delayed puberty among patients was 84.6% and 92.3%, respectively. Conclusion. Low serum leptin is sensitive to predict short stature and significant in β-TM females only. This link could thus be used as a guide for further therapeutic or hormonal modulation. PMID:27088012

    Objective There are some controversial studies on effects of anti-epileptic drugs (AEDs) on serum IgG subclasses; however, the role of these medications is still unclear. The aim of this study was evaluation the effects of anti-epileptic drugs on serum concentration of IgG and its subclasses Methods Serum IgG and IgG subclasses of 61 newly diagnosed epileptic patients were measured at the beginning of monotherapy with carbamazepine, sodium valproate, and phenobarbital, and 6 months later. Measurement of IgG and its subclasses was performed using nephlometry and ELISA techniques, respectively. Findings Reduction of at least one IgG subclass was found in 6 patients 6 months after treatment with AEDs. Among 27 patients receiving carbamazepine, decrease in at least one serum IgG subclass level was found in 5 patients. Among 20 patients using sodium valproate, only one patient showed decrease in IgG2 subclass. None of the 14 patients using phenobarbital revealed significant decrease in IgG subclasses. No infection was seen in the patients with reduction of subclasses. Conclusion Although in our study, children with selective IgG subclass deficiency were asymptomatic, assessment of serum immunoglobulin levels could be recommended at starting the administration of AEDs and in serial intervals afterward in epileptic patients.

    Background: Pulmonary arterial hypertension secondary to untreated left-to-right shunt defects leads to increased pulmonary blood flow, endothelial dysfunction, increased pulmonary vascular resistance, vascular remodelling, neointimal and plexiform lesions. Some recent studies have shown that inflammation has an important role in the pathophysiology of pulmonary arterial hypertension. Aims: The aim of this study is to evaluate serum pentraxin 3 and high sensitive (hs)-C reactive protein (hs-CRP) levels in children with severe pulmonary arterial hypertension (PAH) secondary to untreated congenital heart defects and evaluate the role of inflammation in pulmonary hypertension. Study Design: Cross sectional study. Methods: After ethics committee approval and receiving consent from parents, there were 31 children were selected for the study with severe PAH, mostly with a left-to-right shunt, who had been assessed by cardiac catheterisation and were taking specific pulmonary vasodilators. The control group consisted of 39 age and gender matched healthy children. After recording data about all the patients including age, gender, weight, haemodynamic studies and vasodilator testing, a physical examination was done for all subjects. Blood was taken from patients and the control group using peripheral veins to analyse serum Pentraxin 3, N-terminal pro-Brain Natriuretic Peptide (NT-ProBNP) and hs-CRP levels. Serum Pentraxin-3 levels were measured by enzyme linked immunosorbent assay (ELISA) and expressed as ng/mL. Serum hs-CRP levels were measured with an immunonephelometric method and expressed as mg/dL. The serum concentration of NT-proBNP was determined by a chemiluminescent immunumetric assay and expressed as pg/mL. Results: Serum Pentraxin- 3 levels were determined to be 1.28±2.12 (0.12–11.43) in the PAH group (group 1) and 0.40±0.72 (0.07–3.45) in group 2. There was a statistically significant difference between the two groups (p<0.01). Serum hs-CRP levels were

    Background We conducted a systematic review and meta-analysis to determine the association between serum lipid levels and suicidality, as evidence from previous studies has been inconsistent. Methods We identified relevant studies by searching Medline, Web of Science, EMBASE, and the Cochrane Database of Systematic Reviews (1980 to Dec. 5, 2014). Studies assessing the association between serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and/or triglycerides (TG) levels and suicidality were included. We used a random-effects model to take into account heterogeneity among studies. Results We included 65 studies with a total of 510 392 participants in our analysis. Compared with the nonsuicidal patients, suicidal patients had significantly lower serum TC (weighted mean difference [WMD] −22.35, 95% confidence interval [CI] −27.95 to −16.75), LDL-C (WMD −19.56, 95% CI −26.13 to −12.99) and TG (WMD −23.40, 95% CI −32.38 to −14.42) levels, while compared with the healthy controls, suicidal patients had significantly lower TC (WMD −24.75, 95% CI −27.71 to −21.78), HDL-C (WMD −1.75, 95% CI −3.01 to −0.48) and LDL-C (WMD −3.85, 95% CI −7.45 to −0.26) levels. Furthermore, compared with the highest serum TC level category, a lower serum TC level was associated with a 112% (95% CI 40%–220%) higher risk of suicidality, including a 123% (95% CI 24%–302%) higher risk of suicide attempt and an 85% (95 CI 7%–221%) higher risk of suicide completion. The cut-off values for low and high serum TC level were in compliance with the categories reported in the original studies. Limitations A major limitation of our study is the potential heterogeneity in most of the analyses. In addition, the suicidal behaviour was examined using different scales or methods across studies, which may further explain heterogeneity among the studies. Conclusion We identified an inverse association

    Transport of radionuclides by colloids through the geosphere is an important issue in exercises aimed to assess the safety of an underground radwaste repository sited in a water saturated zone. The first problems to deal with are the characterization of the colloids and their capabilities to sorb, at trace level and even at tracer level, radionuclides. This study investigates the relationships between the sorption of short lived {sup 137}Cs{sup +}, {sup 223}Ra{sup 2+}, {sup 227}Th and {sup 131}I{sup -} and the zeta potential, {zeta}-potential, of well identified colloids, as a function of pH (2 to 11), ionic strength, I (10{sup -3} to 1 M), and colloid concentration (up to 2000 ppm). {xi}-potential is the essential parameter to be considered since it reflects both the stability and the surface charge of the colloid. SiO{sub 2}, TiO{sub 2}, A1{sub 2}O{sub 3} and Th{sub 3}(PO{sub 4}){sub 4} colloids have been chosen as `model colloids`. They are not really found in natural media, but are representative of particles with isoelectric points (i.e.p.) ranging between pH 2 to 9. In some cases the effect of the concentration of the elements has been studied as well, to check saturation effects (Cs and I from 10{sup -11} to 10{sup -2}M). Experimental data show that the distribution of radionuclides between the two phases considered depends mainly on zeta potential, but also on other identified factors.

    PubMed Central

    2010-01-01

    Background Serum 25-hydroxyvitamin D [25(OH)D] is the major circulating form of vitamin D and a standard indicator of vitamin D status. Emerging evidence in the literature suggests a high prevalence of suboptimal vitamin D (as defined by serum 25(OH)D levels of <32 ng/ml) as well as an association between lower serum levels and higher mortality in cancer. We investigated the effect of oral vitamin D supplementation as a means for restoring suboptimal levels to optimal levels in cancer. Methods This is a retrospective observational study of 2198 cancer patients who had a baseline test prior to initiation of cancer therapy at our hospital to evaluate serum 25(OH)D levels between Jan 08 and Dec 09 as part of their initial nutritional evaluation. Patients with baseline levels of < = 32 ng/ml (n = 1651) were considered to have suboptimal serum 25(OH)D levels and were supplemented with 8000 IU of Vitamin D3 (four 2000 IU D3 capsules) daily as part of their nutritional care plan. The patients were retested at their first follow-up visit. Of 1651 patients, 799 were available for follow up assessment. The mean serum 25(OH)D levels were compared in these 799 patients across the 2 time points (baseline and first follow-up) using paired sample t-test. We also investigated the factors associated with response to vitamin D supplementation. Results Of 2198 patients, 814 were males and 1384 females. 1051 were newly diagnosed and treated at our hospital while 1147 were diagnosed and treated elsewhere. The mean age at presentation was 55.4 years. The most common cancer types were breast (500, 22.7%), lung (328, 14.9%), pancreas (214, 9.7%), colorectal (204, 9.3%) and prostate (185, 8.4%). The mean time duration between baseline and first follow-up assessment was 14.7 weeks (median 10.9 weeks and range 4 weeks to 97.1 weeks). The mean serum 25(OH)D levels were 19.1 ng/ml (SD = 7.5) and 36.2 ng/ml (SD = 17.1) at baseline and first follow-up respectively; p < 0.001. Patients with

    Abstract Irisin, a novel exercise-induced myokine, has been suggested to regulate energy homeostasis and insulin sensitivity. However, it remains unclear whether circulating irisin plays a role in the development of DM in human. We investigated the possible association between circulating irisin levels and incident DM in a 2.6-year longitudinal study of a population-based cohort comprised of rural Korean subjects. We conducted a longitudinal study within the Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population (KoGES-ARIRANG) study from November 2005 to January 2008. Cases (n=85) were patients with incident DM during the follow-up period and controls (n = 85) were matched to incident DM cases based on sex and age at baseline. The relative risk of serum irisin/adiponectin level for incident DM was analyzed using conditional logistic regression analysis. Baseline irisin_ENREF_1 levels were significantly higher in subjects who developed DM than in subjects who did not. The serum irisin level was positively associated with glycated hemoglobin (HbA1c) and postprandial glucose. Irisin was negatively associated with adiponectin (R = –0.189, P = 0.014). After adjustment for potential confounders, including body mass index, the odds ratios [95% confidence intervals] for incident DM increased in a graded manner as the serum irisin level increased (Quartile 1 vs Quartile 2 vs Quartile 3 vs Quartile 4 = 1 vs 0.80 [0.28–2.35] vs 3.33 [1.11–10.00] vs 4.10 [1.35–12.44], respectively), whereas the odds ratios for incident DM decreased in a graded manner as the serum adiponectin level increased. High serum irisin was independently associated with the development of DM, indicating that irisin may be a useful predictor of DM in Korean adults. PMID:27281072

    The aim of this study was to determine serum vitamin B12, folic acid and homocysteine (Hcy) levels as well as MTHFR (C677, A1298C) gene polymorphisms in patients with vitiligo, and to compare the results with healthy controls. Forty patients with vitiligo and 40 age and sex matched healthy subjects were studied. Serum vitamin B12 and folate levels were determined by enzyme-linked immunosorbent assay. Plasma Hcy levels and MTHFR polymorphisms were determined by chemiluminescence and real time PCR methods, respectively. Mean serum vitamin B12 and Hcy levels were not significantly different while folic acid levels were significantly lower in the control group. There was no significant relationship between disease activity and vitamin B12, folic acid and homocystein levels. No significant difference in C677T gene polymorphism was detected. Heterozygote A1298C gene polymorphism in the patient group was statistically higher than the control group. There was no significant relationship between MTHFR gene polymorphisms and vitamin B12, folic acid and homocysteine levels. In conclusion, vitamin B12, folate and Hcy levels are not altered in vitiligo and MTHFR gene mutations (C677T and A1298C) do not seem to create susceptibility for vitiligo. PMID:22846211

    Background and Aims. To examine the changes in serum alpha-fetoprotein (AFP) levels after iron reduction by therapeutic phlebotomy in chronic hepatitis C patients. Methods. This retrospective study included 26 chronic hepatitis C patients. The patients were developed iron depletion by repeated therapeutic phlebotomies. Results. Iron reduction therapy significantly reduced the median level of serum AFP from 13 to 7 ng/mL, ALT from 96 to 50 IU/L, gamma-glutamyl transpeptidase (GGT) from 55 to 28 IU/L, and ferritin from 191 to 10 ng/mL (P < 0.001 for each). The rate of decline in the AFP level correlated positively only with that in GGT (r = 0.695, P = 0.001), although a spurious correlation was observed between the rates of decline for AFP and ALT. The AFP level normalized (<10 ng/mL) posttreatment in eight (50%) of 16 patients who had elevated pretreatment AFP levels. Normalized post-treatment ALT and GGT levels were seen in 12% (3 of 26) and 39% (7 of 18) of the patients, respectively. Multivariate analysis identified a post-treatment GGT level of <30 IU/L as an independent factor associated with post-treatment AFP normalization (odds ratio, 21; 95% confidence interval, 1.5–293; P = 0.024). Conclusions. Iron reduction by therapeutic phlebotomy can reduce serum AFP and GGT levels in chronic hepatitis C patients.

    Repetin (RPTN) protein is a member of S100 family and is known to be expressed in the normal epidermis. Here we show that RPTN is ubiquitously expressed in both mouse and human brain, with relatively high levels in choroid plexus, hippocampus and prefrontal cortex. To investigate the expression of RPTN in neuropsychiatric disorders, we determined serum levels of RPTN in patients with schizophrenia (n = 88) or bipolar disorder (n = 34) and in chronic psychostimulant users (n = 91). We also studied its expression in a mouse model of chronic unpredictable mild stress (CUMS). The results showed that serum RPTN levels were significantly diminished in patients with schizophrenia and bipolar disorder or in psychostimulant users, compared with healthy subjects (n = 115) or age-matched controls (n = 92) (p < 0.0001). In CUMS mice, RPTN expression in hippocampus and prefrontal cortex was reduced with progression of the CUMS procedure; the serum RPTN level remained unchanged. Since CUMS is a model for depression and methamphetamine (METH) abuse induced psychosis recapitulates many of the psychotic symptoms of schizophrenia, the results from this study may imply that RPTN plays a potential role in emotional and cognitive processing; its decrease in serum may indicate its involvement in the pathogenesis of schizophrenia and bipolar disorder.

    Background: Cyclosporine and tacrolimus are limited by a narrow therapeutic window. Maintaining immunosuppressive drugs at desired levels may be difficult. Pharmaceutical care emerges as a philosophy of practice that enhances medication use and leads to a better control of serum concentration. Objective: This study aims to evaluate the impact of pharmaceutical care in the maintaining of proper serum levels of immunosuppressive medications in patients who have undergone allo-HSCT. Methods: The study had a quasi-experimental design that included a comparison group. The service model used was pharmacotherapy follow-up, according to an adaptation of the Dader method. The pharmacist consultation was carried out at a day-hospital or at the outpatient hematology clinic as needed. The intervention group consisted of 22 patients seen by a clinical pharmacist. The control group consisted of 44 patients that received standard care. This study aims to evaluate the impact of pharmaceutical care on keeping patient serum levels of cyclosporine and tacrolimus within the desired range. Results: Control group displayed 65% of the proper serum levels of immunosuppressive agents. While In intervention group, the figure was 82% (p = 0.004). Conclusion: The role of the pharmacist in the multidisciplinary team may contribute to a greater success in attaining the patients’ therapeutic targets with regard to the use of immunosuppressant.

    /sup 67/Ga citrate scans and serum angiotensin converting enzyme (ACE) levels were obtained in 54 patients with sarcoidosis and analyzed in relation to clinical manifestations. /sup 67/Ga scans were abnormal in 97% of patients with clinically active disease (n . 30) and in 71% of patients with inactive disease (n . 24). Serum ACE levels were abnormally high (2 standard deviations above the control mean) in 73% of patients with clinically active disease and in 54% of patients with inactive disease. Serum ACE levels correlated significantly with /sup 67/Ga uptake score (r..436; p less than .005). The frequency of abnormal /sup 67/Ga scans and elevated serum ACE levels suggests that inflammatory activity with little or no clinical expression is common in sarcoidosis. Abnormal /sup 67/Ga scans were highly sensitive (97%) but had poor specificity (29%) to clinical disease activity. The accuracy of negative prediction of clinical activity by normal scans (87%) was better than the accuracy of positive prediction of clinical activity by abnormal scans (63%). /sup 67/Ga scans can be used to support the clinical indentification of inactive sacoidosis.

    IL-33 is a recently identified cytokine, encoded by the IL-33 gene, which is a member of the IL-1 family that drives the production of T-helper-2 (Th-2)-associated cytokines. Serum levels of IL-33 have been reported to be up-regulated in various T-helper (Th)-1/Th-17-mediated diseases, such as psoriasis, rheumatoid arthritis, and inflammatory bowel. To investigate whether cytokine imbalance plays a role in the pathogenesis of vitiligo, we performed a case-control association study by enzyme-linked immunosorbent assay of IL-33 in our patients. IL-33 serum levels were measured by a quantitative enzyme immunoassay technique in patients with non-segmental generalized vitiligo and compared with those of healthy controls. IL-33 serum levels in patients with vitiligo were significantly increased than those in healthy controls. There was a positive correlation of IL-33 serum levels with extension of vitiligo and disease activity. This study suggests a possible systemic role of IL-33 in the pathogenesis of vitiligo. Inhibiting IL-33 activity might be a novel therapeutic strategy in the treatment of autoimmune inflammatory disease, like vitiligo. PMID:27388717

    Growing evidence identifies histamine as a key player in allergic responses, but the reports relating serum histamine to tolerance are scarce and inconclusive. This study investigated the relationship of circulating histamine to the tolerant phenotype in allergic beekeepers. The results showed a positive correlation between the serum levels of histamine and specific immunoglobulin G4 (sIgG4) to honeybee venom, but not with total IgE or sIgE. Interestingly, both sIgG4 and histamine levels were negatively correlated with the time since the last bee sting. In contrast to total IgE and sIgE, serum sIgG4 and histamine levels followed comparable patterns, being higher in tolerant/recently stung individuals and lower in the least frequently stung subgroup. The data obtained in this pilot study associated, for the first time, serum histamine levels with allergen tolerance in allergic individuals and provided the lead for further considering the putative immunomodulatory properties of histamine in allergic responses.

    Objective To investigate the correlation between depressive symptoms and serum vitamin D levels in stroke patients. Methods In total, 126 stroke patients were analyzed. The 25-hydroxyvitamin D (25-OHD) concentration of each patient was used to determine their vitamin D status. Depressive symptoms were assessed using the Beck Depression Inventory II (BDI-II) and the Patient Health Questionnaire 9 (PHQ-9). Functional status was evaluated with the Korean version of the Modified Barthel Index (K-MBI). We compared the clinical questionnaires of a vitamin D-deficient group and a normal group, and evaluated the correlations between BDI-II, PHQ-9, K-MBI, and serum 25-OHD levels. Results In the vitamin D-deficient group, BDI-II (16.0±12.1) and PHQ-9 (7.4±4.2) scores were significantly higher than those of the normal group (BDI-II, 9.1±7.2; PHQ-9, 4.2±2.9; p<0.01). In a Spearman correlation analysis, a significant negative correlation was found between serum 25-OHD levels and BDI-II (Spearman r=0.177, p=0.048), but there were no significant correlations between serum 25-OHD levels and PHQ-9 or K-MBI. Conclusion Vitamin D deficiency was correlated with the symptoms of depression in stroke patients. PMID:26949678

    2016-01-01

    Background  Despite its seldom occurrence, fetal tachycardia can lead to poor fetal outcomes including hydrops and fetal death. Management can be challenging and result in maternal adverse effects secondary to high serum drug levels required to achieve effective transplacental antiarrhythmic drug therapy. Case  A 33-year-old woman at 33 weeks of gestation with a diagnosis of a fetal sustained superior ventricular tachycardia developed chest pain, shortness of breath, and bigeminy on electrocardiogram secondary to digoxin toxicity despite subtherapeutic serum drug levels. She required supportive care with repletion of corresponding electrolyte abnormalities. After resolution of cardiac manifestations of digoxin toxicity, the patient was discharged home. The newborn was discharged at day 9 of life on maintenance amiodarone. Conclusion  We describe an interesting case of digoxin toxicity with cardiac manifestations of digoxin toxicity despite subtherapeutic serum drug levels. This case report emphasizes the significance of instituting an early diagnosis of digoxin toxicity during pregnancy, based not only on serum drug levels but also on clinical presentation. In cases of refractory supportive care, digoxin Fab fragment antibody administration should be considered. With timely diagnosis and treatment, excellent maternal and perinatal outcomes can be achieved. PMID:27516921

    Background. The reduction mammaplasty has been a well-executed and known procedure in which considerable amount of fatty tissue is removed from the body. The authors aimed to show the effects of the reduction mammaplasty on serum leptin levels and insulin resistance. Methods. 42 obese female patients who had gigantomastia were operated on. We recorded patients' demographic and preoperative data, including age, weight, height, and body mass index. Fasting serum leptin, glucose, and insulin levels were noted. Homeostasis model assessment scores were calculated. At the postoperative 8th week, patients were reevaluated in terms of above parameters assessing the presence of any difference. Results. Serum leptin levels were decreased postoperatively and the decrease was statistically significant. We were able to show a decrease in homeostasis model assessment score, which indicated an increase in insulin sensitivity, and this change was statistically significant. A significant correlation between body mass index and leptin change was found postoperatively. Conclusion. Reduction mammaplasty is not solely an aesthetic procedure but it decreases serum leptin levels and increases insulin sensitivity, which may help obese women to reduce their cardiovascular risk.

    Serum levels of soluble CD44 variant proteins including sequences encoded by exon v5 and exon v6 (sCD44v5, sCD44v6) were determined in patients with inflammatory rheumatic diseases: 56 with rheumatoid arthritis (RA+) and 31 with miscellaneous inflammatory rheumatic diseases (MIRD). There were very significantly higher serum levels of sCD44v5 and sCD44v6 in patients with RA+ than in those with MIRD (RA+ to MIRD: sCD44v5: 81 +/- 54 ng/ml to 33 +/- 13 ng/ml; sCD44v6: 237 +/- 124 ng/ml to 166 +/- 53 ng/ml; both P < 0.001). In RA+ elevated serum levels of sCD44v5 were correlated with the inflammatory activity of disease. In 17 patients with RA+ three or four follow-up measurements of sCD44v5 were performed within 6 months. The development of sCD44v5 serum levels reflected the clinical course of disease in the patients investigated. PMID:9032816

    Micronutrients serve many important functions in our body and altered levels of heavy and trace metals are associated with cutaneous and systemic disorders. Vesicular palmoplantar eczema is an entity whose etiopathogenesis is a mystery. In this prospective case-noncase study blood levels of Zinc and Cadmium in 37 patients of chronic vesiculobullous hand dermatitis were estimated and compared with 40 noncases with similar age and gender distributions. Low serum Zinc levels were found in patients as compared to noncases. The mean difference of serum Zinc between the case and noncase groups was 27.26; the mean value of serum Zinc between the two groups was statistically significant (p < 0.0001). However, elevated Cadmium levels were detected in only 5 patients and in none of the noncases. The mean concentration of serum Cadmium was 2.32 ± 0.38 μg/dL, with a range of 1.90–2.80 μg/dL for the five cases in whom Cadmium was detected. Various toxic and trace metals can interact by influencing each other's absorption, retention, distribution, and bioavailability in the body. The clinical significance of this finding lies in the possible beneficial role of Zinc supplementation in the therapy of chronic vesiculobullous hand dermatitis. PMID:27143960

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

    Lung cancer is one of the most common cancers worldwide and is the leading cause of cancer-induced death in the USA. Although much attention has been focused on the anti-carcinogenic effect of consuming carotenoid-containing food or supplements, the results have been inconsistent. We investigated whether serum carotenoid levels were associated with the mortality risk of lung cancer in US adults using data from a nationally representative sample. The data were obtained from the Third Nutrition and Health Examination Survey (NHANES III) database and the NHANES III Linked Mortality File. A total of 10 382 participants aged over 20 years with available serum carotenoid levels and no other missing information on questionnaires and biomarkers at baseline (NHANES III) were included in the present study. Of the 10 382 participants, 161 subjects died due to lung cancer. We found that high serum levels of alpha-carotene and beta-cryptoxanthin at baseline were significantly associated with a lower risk of lung cancer death. When we stratified the risk by current smoking status, the risk of death of current smokers was significantly decreased to 46% (95% confidence interval, 31–94%) for alpha-carotene and 61% (95% confidence interval, 19–80%) for beta-cryptoxanthin. By contrast, no association was observed among never/former smokers at baseline. High serum levels of alpha-carotene and beta-cryptoxanthin are associated with a lower risk of lung cancer death in US adults. PMID:24673770

    Both endothelial lipase gene (LIPG) 584C>T (rs2000813) polymorphism and alcohol consumption modulate serum lipid levels. But their interactions on serum lipid profiles are not well known. The present study was undertaken to detect the interactions of LIPG 584C>T polymorphism and alcohol consumption on serum lipid levels. Genotyping of the LIPG 584C>T was performed in 763 unrelated nondrinkers and 520 drinkers aged 15-85 years. The levels of serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), apolipoprotein (Apo) AI, and the ratio of ApoAI to ApoB were higher in drinkers than in nondrinkers (P<.01 for all). There were no significant differences in the genotypic and allelic frequencies between nondrinkers and drinkers. The levels of TC, HDL-C, and ApoAI in nondrinkers were different among the three genotypes (P<.05-.01), the subjects with CT genotype had higher TC, HDL-C, and ApoAI levels than the subjects with CC genotype. The levels of HDL-C and ApoAI in drinkers were different among the three genotypes (P<.001 and P<.05; respectively), the individuals with TT genotype had higher HDL-C and ApoAI levels than the individuals with CT and CC genotypes. The interactions between LIPG 584C>T genotypes and alcohol consumption on serum HDL-C (P<.01) and ApoAI levels (P<.05) were also detected by using a factorial regression analysis after controlling for potential confounders. The levels of TC in nondrinkers were correlated with LIPG 584C>T alleles (P<.05), whereas the levels of TG and HDL-C were associated with LIPG 584C>T alleles (P<.05) and genotypes (P<.05), respectively. These results suggest that the subjects with TT genotype benefit more from alcohol consumption than the subjects with CT and CC genotypes in increasing serum HDL-C and ApoAI levels. PMID:21816559

    Immunoglobulin A nephropathy (IgAN) is an immunopathologic diagnosis based on a renal biopsy, it is characterized by deposits of IgA-containing immune complexes in the mesangium. Adults with IgAN have a galactose-deficient IgA1 in the circulation and glomerular deposition. There are few studies on the glycosylation of serum IgA1 in children with IgAN. To measure the serum levels of galactose-deficient IgA1 in pediatric patients with IgAN, 72 biopsy-proven IgAN children were divided into 3 groups based on the clinical features: isolated hematuria group (24 patients), hematuria and proteinuria group (22 patients), and nephritic syndrome group (26 patients). They were also divided into 3 groups according to pathologic grading: grade I + II group (25 patients), grade III group (33 patients) and grade IV + V group (14 patients). 30 healthy children were recruited as a control group. We used vicia villosa lectin binding enzyme-linked immunosorbent assay to measure the serum levels of galactose-deficient IgA1 in all groups and controls. Serum levels of galactose-deficient IgA1 in children with IgAN were higher than controls (P < 0.01). There were no significant differences in serum levels of galactose-deficient IgA1 among the different clinical and pathologic grading groups. The values of the area under the curve for galactose-deficient IgA1 levels were 0.976 (95% CI, 0.953-1.000). The cutoff point for galactose-deficient IgA1 levels was 0.125, with a sensitivity of 87.5% and a specificity of 83.3%, with a positive predictive value of 92.6% and a negative predictive value of 73.5% (P < 0.01). Children with IgAN presented serum galactose-deficient IgA1, which has shown no relationship with the clinical manifestations and pathologic grading of the disease. Detection of serum galactose-deficient IgA1 levels by vicia villosa lectin binding enzyme-linked immunosorbent assay has a certain clinical value in diagnosis of children with IgAN. PMID:26221341

    Background Dry eye syndrome (DES) is a common tear film and ocular surface disease that results in discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. Systemic diseases associated with DES include diabetes mellitus, rheumatoid arthritis, depression, anxiety, thyroid disease, allergic diseases, irritable bowel syndrome, chronic pain syndrome, and hyperlipidemia. Interestingly, it has been found that most of these are associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) or inadequate sunlight exposure. Methods In this cross-sectional data analysis, noninstitutionalized adults aged ≥19 years (N = 17,542) who participated in Korean National Health and Nutrition Examination Survey 2010–2012 were included. Information regarding duration of sunlight exposure was collected from the survey participants. Serum 25(OH)D and zinc levels were measured. The confounding variables were age, gender, sunlight exposure time, region of residence, obesity, serum 25(OH)D level, diabetes mellitus, rheumatoid arthritis, depression, thyroid disorder, atopic dermatitis, history of ocular surgery, regular exercise, and walking exercise. Results Mean serum 25(OH)D levels of subjects with and without DES were 16.90 ± 6.0 and 17.52 ± 6.07 (p<0.001). Inadequate sunlight exposure time (odds ratio [OR], 1.554; 95% confidence interval [CI], 1.307–1.848), urban residence (OR, 1.669; 95% CI, 1.456–1.913), indoor occupation (OR, 1.578; 95% CI, 1.389–1.814), and low serum 25(OH)D level (OR, 1.158; 95% CI, 1.026–1.308) were the risk factors for DES. After adjusting for age, sex, obesity, diabetes mellitus, rheumatoid arthritis, depression, thyroid disorder, atopic dermatitis, history of ocular surgery, regular exercise, and occupation, low serum 25(OH)D level (OR, 1.178; 95% CI, 1.010–1.372) and deficient sunlight exposure time (OR, 1.383; 95% CI, 1.094–1.749) were the risk factors for diagnosed DES.

    Immunoglobulin A nephropathy (IgAN) is an immunopathologic diagnosis based on a renal biopsy, it is characterized by deposits of IgA-containing immune complexes in the mesangium. Adults with IgAN have a galactose-deficient IgA1 in the circulation and glomerular deposition. There are few studies on the glycosylation of serum IgA1 in children with IgAN. To measure the serum levels of galactose-deficient IgA1 in pediatric patients with IgAN, 72 biopsy-proven IgAN children were divided into 3 groups based on the clinical features: isolated hematuria group (24 patients), hematuria and proteinuria group (22 patients), and nephritic syndrome group (26 patients). They were also divided into 3 groups according to pathologic grading: grade I + II group (25 patients), grade III group (33 patients) and grade IV + V group (14 patients). 30 healthy children were recruited as a control group. We used vicia villosa lectin binding enzyme-linked immunosorbent assay to measure the serum levels of galactose-deficient IgA1 in all groups and controls. Serum levels of galactose-deficient IgA1 in children with IgAN were higher than controls (P < 0.01). There were no significant differences in serum levels of galactose-deficient IgA1 among the different clinical and pathologic grading groups. The values of the area under the curve for galactose-deficient IgA1 levels were 0.976 (95% CI, 0.953-1.000). The cutoff point for galactose-deficient IgA1 levels was 0.125, with a sensitivity of 87.5% and a specificity of 83.3%, with a positive predictive value of 92.6% and a negative predictive value of 73.5% (P < 0.01). Children with IgAN presented serum galactose-deficient IgA1, which has shown no relationship with the clinical manifestations and pathologic grading of the disease. Detection of serum galactose-deficient IgA1 levels by vicia villosa lectin binding enzyme-linked immunosorbent assay has a certain clinical value in diagnosis of children with IgAN. PMID:26221341

    Background Low serum ferritin levels signify low iron stores and this could predispose to iron deficiency anemia. Objective To determine the rate and predictors of low serum ferritin levels during the puerperium in Enugu, Southeast Nigeria. Study design A hospital-based prospective longitudinal study involving parturient women who delivered singleton fetuses at term. Venous blood samples were collected to determine the serum ferritin concentration at 48 hours and 6 weeks postpartum. Data analysis involved descriptive and inferential statistics at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) computer software version 20.0. Results Two-hundred and two women who carried singleton pregnancies to term were studied. The mean serum ferritin levels at 48 hours and 6 weeks were 27.82±18.41 µg/L and 36.12±21.53 µg/L, respectively. Forty-eight hours postdelivery, 29.2% had low ferritin levels and this decreased to 12.4% at 6 weeks postpartum. There was a significant positive correlation between the serum ferritin level at 48 hours postdelivery and the serum ferritin level at 6 weeks postpartum (r=0.89, P<0.001). Predictors of the low ferritin level at 6 weeks included age <20 years (odds ratio [OR] =0.70, 95% CI =0.53, 0.93), multiparity (OR =63.7, 95% CI =3.18, 127.5), anemia at 48 hours postpartum (OR =61.7, 95% CI =13.27, 116.6), a low ferritin level at 48 hours (OR =78.1, 95% CI =8.8, 108.3), and intake of antenatal hematinics for <3 months (OR =0.04, 95% CI =0.01, 0.20). Conclusion There was a significant occurrence of low ferritin levels during the puerperium in the study centers, and this was associated mainly with pregnancy and delivery factors. Efforts to improve the iron stores in parturient women could benefit from early booking and compliance with antenatal hematinics and optimizing hemoglobin and iron levels before delivery.

    Obesity is more frequent in bipolar disorder. Adipokines are associated with depression and obesity via the inflammatory process. Twenty-six DSM-IV patients with BD and 39 controls were enrolled to assess the relationship between serum leptin and adiponectin with hippocampal volumes. Among patients, there was a significant negative correlation between right hippocampal volume and serum leptin levels. This result sum for the hypothesis of a pro-inflammatory state associated with BD and the prevalent co-morbid obesity. PMID:26434408

    Galanin (GAL) is a neuropeptide involved in the homeostasis of energy metabolism. The objective of this study was to investigate the serum levels of GAL during an oral glucose tolerance test (OGTT) in lean and obese young men. This cross-sectional study included 30 obese non-diabetic young men (median 22 years; mean BMI 37 kg/m(2)) and 30 healthy lean men (median 23 years; mean BMI 22 kg/m(2)). Serum GAL was determined during OGTT. The results of this study include that serum GAL levels showed a reduction during OGTT compared with basal levels in the lean subjects group. Conversely, serum GAL levels increased significantly during OGTT in obese subjects. Serum GAL levels were also higher in obese non-diabetic men compared with lean subjects during fasting and in every period of the OGTT (p < 0.001). Serum GAL levels were positively correlated with BMI, total fat, visceral fat, HOMA-IR, total cholesterol, triglycerides and Leptin. A multiple regression analysis revealed that serum insulin levels at 30, 60 and 120 minutes during the OGTT is the most predictive variable for serum GAL levels (p < 0.001). In conclusion, serum GAL levels are significantly higher in the obese group compared with lean subjects during an OGTT. PMID:27550417

    One of the most common disorders of the endocrine system is diabetes mellitus. This disease is associated with dyslipidemia. Adiponectin is a protein hormone that secreted by adipocytes and has an important role in regulating of glucose and fatty acid metabolic pathways. This study was designed to investigate the changes in serum level of adiponectin in diabetic rats treated with hydroalcoholic extracts of three medicinal plants; jujube (Ziziphus jujuba), barberry (Berberis vulgaris) and saffron (Crocus sativus) in comparison with quercetin. Streptozotocin -induced diabetic male rats were gavaged with specified doses of the extracts (25 and 100mg/kg) for two weeks. At the end of treatment period, fasting blood specimens were collected. The levels of adiponectin, fasting blood sugar (FBS), total Cholesterol, triglycerides, HDL-C and LDL-C were measured. Statistical analysis showed that serum levels of triglyceride and VLDL decreased significantly (P<0.05) in all treated groups. FBS level in all treated groups, decreased significantly and reach to normoglycemic level (P<0.05). Except Jujube, other plant extracts had no effect on cholesterol. Jujube in two doses (25 and 100mg/kg) could increased significantly HDL-C (P<0.05) with no effect on total cholesterol and LDL-C. Serum adiponectin level increased in all treated groups. These beneficial effects of C. sativus, B. vulgaris and Z. jujube extracts and quercetin in diabetic rats may be associated with increase in adiponectin level. PMID:26639503

    The aim of this study was to investigate the effects of basal insulin application on the serum visfatin and adiponectin (APN) levels of patients with type 2 diabetes mellitus (T2DM). A total of 200 patients with T2DM, who were diagnosed in The Third People's Hospital of Jinan (glycosylated hemoglobin ≥7%), were randomly divided into treatment and control groups. The patients used only oral hypoglycemic drugs and had never received insulin therapy. In the treatment group, basal insulin was administered in combination with the original application of oral hypoglycemic drugs, whereas the control group maintained the original use of oral hypoglycemic drugs or took other oral hypoglycemic agents. The body mass index and fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin, visfatin, APN and blood lipid levels of the patients were examined prior to the treatment and six months later. The drug and insulin doses in the treatment group were adjusted according to the patients' blood glucose, which allowed the fasting and postprandial blood glucose levels to attain the standards. The fasting and postprandial blood glucose levels in the control group also achieved the standards. It was found that the six-month application of basal insulin could significantly decrease the glycosylated hemoglobin and significantly increase the serum APN levels; the serum visfatin levels, however, remained unchanged. The immediate application of basal insulin could facilitate the attainment of glycosylated hemoglobin standards in T2DM and could increase the plasma APN levels, preventing diabetic vascular complications.

    The purpose of our study is to examine the association between serum GGT levels and ventricular instability in Chinese patients with T2DM. We conducted a cross-sectional, community-based study in Nanjing, China from June to November 2011. Among 10,050 patients aged 40-79 years, we enrolled 2444 with pre-diabetes, 2496 with T2DM, and 4521 without diabetes (non-diabetes). Electrocardiograms were performed to measure the QT interval corrected for heart rate (QTc) and QT interval dispersion (QTd). Serum GGT levels, metabolic parameters, body mass index, and blood pressure were also measured. We found that there were no significant associations of increased QTc/QTd with serum GGT levels in participants with pre-existing T2DM and non-diabetes, after adjusting for age, duration of diabetes, and metabolic parameters. Even after adjustment, higher risks of QTc ≥ 440 ms/√s and QTd ≥ 58 ms were found in participants with serum GGT levels ≥49 U/L compared with those with <15 U/L in the pre-diabetes (QTc: OR 1.96, 95 % CI 1.23-2.47; QTd: OR 1.34, 95 % CI 1.07-1.94) and newly diagnosed T2DM (QTc: OR 2.01, 95 % CI 1.39-2.51; QTd: OR 1.53, 95 % CI 1.03-1.99) groups. We conclude that Increased serum GGT levels are associated with some markers of ventricular repolarization abnormalities in the early stage of T2DM. PMID:26433737

    Public Health Annals recording diagnosis of nutritional rickets in patients admitted in Public Hospitals disclosed that from birth to age 14, in the period 1980-1981, the incidence was 2.7 higher in the Patagonia (latitude 39 degrees S to 55 degrees S) compared with the Pampeana Region and 8.5 higher than in the rest of the country. After informed parental consent 37 healthy children of Buenos Aires (34 degrees S) with an age of (Av +/- 1 SD) 7.0 +/- 1.2 years, 29 with an age of 13.1 +/- 1.5 years and 63 of Ushuaia (55 degrees S) with an age of 7.1 +/- 0.8 years were studied at the end of winter (August). Serum levels of 25-OH-D were as follows (mean +/- SE): Buenos Aires: 21.1 +/- 2.03 ng/ml (Average: seven years old), 19.0 +/- 1.18 ng/ml (children of thirteen years old) and Ushuaia: 9.3 +/- 0.64 ng/ml (p less than 0.001) (Fig. 2). Serum levels were below 8 ng/ml in 52% of the children in Ushuaia but only in 9% in Buenos Aires. Serum calcium and alkaline phosphatase levels were similar in the two groups but serum phosphate was higher in Ushuaia (Table 1). The calcium intake was greater in Ushuaia (811 +/- 49 mg/day) than in Buenos Aires (634 +/- 61 mg/day) and was correlated with 25-OH-D levels in children of Ushuaia (r = 0.50, p less than 0.001) but not in Buenos Aires (r = 0.08). The main source of calcium intake was vitamin D fortified milk. These results disclosed a significantly diminished level of serum 25-OH-D in Ushuaia.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2130224

    BACKGROUND We previously cloned prosaposin (PSAP) from metastatic castrate-resistant prostate cancer (mCRPCa) cells and demonstrated its genomic amplification and/or overexpression in metastatic PCa cell lines, xenografts, and lymph node metastases. The clinicohistopathological significance of serum-PSAP levels and its tissue expression and association with predictive or prognostic variable in primary or advanced PCa are not known. METHODS We examined PSAP expression by immunohistochemical staining during early embryogenic development of the prostate and within a large tissue microarray which included 266 benign and malignant prostate tissues. In addition, serum PSAP levels in the age-adjusted normal male population and in 154 normal individuals and patients with primary or mCRPCa were measured by an ELISA assay. RESULTS Univariate and multivariate analyses revealed a significant and inverse association between PSAP expression and clinical stage II and III tumors, dominant Gleason patterns 3 and 4, and seminal vesicle invasion. In the normal male population, the lowest serum-PSAP level was detected before puberty, peaked at the most reproductive age group (20–39 years old), and then, decreased to a range between the two groups for men above 40 years old. Regardless of age and when compared with normal individuals, serum-PSAP levels significantly decreased in primary organ-confined PCa, but increased in those with mCRPCa. CONCLUSION Our results show that PSAP has the potential to differentiate between primary and advanced PCa. Additional large-scale studies are needed to define the usefulness of tissue expression or serum-PSAP levels as a diagnostic or prognostic marker or as a therapeutic target in PCa. PMID:21630292

    The Muslims fast every year during the month of Ramadan. A fasting day can last 12-17 h. The effects of fasting on serum lithium levels and the mood changes in patients suffering from bipolar affective disorder during Ramadan are not well studied. We aimed to compare the serum lithium levels, side effects, toxicity and mental state in patients suffering from bipolar affective disorder and on prophylactic lithium therapy before, during and after Ramadan. Sixty-two patients meeting the International Classification of Diseases, Tenth Revision, Research Diagnostic Criteria of bipolar affective disorder receiving lithium treatment for prophylaxis were recruited in a tertiary care teaching hospital in Peshawar, Pakistan. Serum lithium, electrolytes, Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) were assessed at three points, 1 week before Ramadan, midRamadan and 1 week after Ramadan. The side effects and toxicity were measured by a symptoms and signs checklist. There was no significant difference in mean serum lithium levels at three time points (preRamadan=0.45±0.21, midRamadan=0.51±0.20 and postRamadan=0.44±0.23 milli equivalents/litre, P=0.116). The scores on HDRS and YMRS showed significant decrease during Ramadan (F=34.12, P=0.00, for HDRS and F=15.6, P=0.000 for YMRS). The side effects and toxicity also did not differ significantly at three points. In conclusion, the patients who have stable mental state and lithium levels before Ramadan can be maintained on lithium during Ramadan. Fasting in an average temperature of 28°C for up to 12 h per day did not result in elevated serum lithium levels or more side effects and did not have adverse effects on mental state of patients suffering from bipolar affective disorder.

    Background Gamma-glutamyltransferase (GGT) is a biomarker of liver injury. GGT has also been reported to be a marker of oxidative stress and a predictor of mortality in the general population. Hemodialysis (HD) patients suffer from oxidative stress. The aim of our study was to investigate the relationship between serum GGT levels and clinical outcomes in HD patients. Methods A total of 1,634 HD patients were enrolled from the Clinical Research Center registry for end-stage renal disease, a prospective cohort in Korea. Patients were categorized into three groups by tertiles of serum GGT levels. The primary outcome was all-cause, cardiovascular, or infection-related mortality and hospitalization. Results During the median follow-up period of 30 months, the highest tertile of serum GGT levels had a significantly higher risk for all-cause mortality (hazard ratio (HR) 2.39, 95% confidence interval (CI), 1.55–3.69, P<0.001), cardiovascular mortality (HR 2.14, 95% CI, 1.07–4.26, P = 0.031) and infection-related mortality (HR 3.07, 95% CI, 1.30–7.25, P = 0.011) using tertile 1 as the reference group after adjusting for clinical variables including liver diseases. The highest tertile also had a significantly higher risk for first hospitalization (HR 1.22, 95% CI, 1.00–1.48, P = 0.048) and cardiovascular hospitalization (HR 1.42, 95% CI, 1.06–1.92, P = 0.028). Conclusions Our data demonstrate that high serum GGT levels were an independent risk factor for all-cause, cardiovascular, and infection-related mortality, as well as cardiovascular hospitalization in HD patients. These findings suggest that serum GGT levels might be a useful biomarker to predict clinical outcomes in HD patients. PMID:26376075

    Alcoholic hepatitis (AH) frequently progresses to multiple organ failure (MOF) and death. However, the driving factors are largely unknown. At admission, patients with AH often show criteria of systemic inflammatory response syndrome (SIRS) even in the absence of an infection. We hypothesize that the presence of SIRS may predispose to MOF and death. To test this hypothesis, we studied a cohort including 162 patients with biopsy-proven AH. The presence of SIRS and infections was assessed in all patients, and multivariate analyses identified variables independently associated with MOF and 90-day mortality. At admission, 32 (19.8%) patients were diagnosed with a bacterial infection, while 75 (46.3%) fulfilled SIRS criteria; 58 patients (35.8%) developed MOF during hospitalization. Short-term mortality was significantly higher among patients who developed MOF (62.1% versus 3.8%, P <0.001). The presence of SIRS was a major predictor of MOF (odds ratio = 2.69, P=0.025) and strongly correlated with mortality. Importantly, the course of patients with SIRS with and without infection was similar in terms of MOF development and short-term mortality. Finally, we sought to identify serum markers that differentiate SIRS with and without infection. We studied serum levels of high-sensitivity C-reactive protein, procalcitonin, and lipopolysaccharide at admission. All of them predicted mortality. Procalcitonin, but not high-sensitivity C-reactive protein, serum levels identified those patients with SIRS and infection. Lipopolysaccharide serum levels predicted MOF and the response to prednisolone. Conclusion In the presence or absence of infections, SIRS is a major determinant of MOF and mortality in AH, and the mechanisms involved in the development of SIRS should be investigated; procalcitonin serum levels can help to identify patients with infection, and lipopolysaccharide levels may help to predict mortality and the response to steroids.

    Progranulin (PGRN) is implicated in infection, immunity and host defense, but its role in the pathogenesis of HBV infection remains unknown. Here we investigated whether there is dysregulated production and the clinical significance of circulating PGRN in patients with chronic HBV infection. Serum concentrations of PGRN were analyzed by enzyme-linked immunosorbent assay. Serum PGRN levels were significantly higher in patients with chronic HBV infection than healthy subjects. PGRN levels were significantly associated with HBV-DNA levels, but did not correlate with the concentrations of alanine aminotransferase and aspartate aminotransferase. This study demonstrates increased circulating PGRN production and association between PGRN levels and viral loads in patients with chronic HBV infection, suggesting a functional role of PGRN in the pathogenesis of HBV infection.

    Streptococcus pneumoniae is a major cause of life-threatening infections. Complement activation plays a vital role in opsonophagocytic killing of pneumococci in blood. Initial complement activation via the classical and lectin pathways is amplified through the alternative pathway amplification loop. Alternative pathway activity is inhibited by complement factor H (FH). Our study demonstrates the functional consequences of the variability in human serum FH levels on host defense. Using an in vivo mouse model combined with human in vitro assays, we show that the level of serum FH correlates with the efficacy of opsonophagocytic killing of pneumococci. In summary, we found that FH levels determine a delicate balance of alternative pathway activity, thus affecting the resistance to invasive pneumococcal disease. Our results suggest that variation in FH expression levels, naturally occurring in the human population, plays a thus far unrecognized role in the resistance to invasive pneumococcal disease.

    The present communication deals with information regarding the practice of the oral glucose tolerance test and determination of serum fructosamine in laboratory beagles. In the oral glucose tolerance test, a 180-min level was found to be crucial following a gavage administration of 50% glucose solution at 5 mL/kg per body weight under fasting conditions. Serum fructosamine concentration as 'determined by enzymatic assay ranged between 82 and 123 micromol/L (mean of 104 micromol/L), which was about 0.285 to 0.25 times the value obtained by the chemical method described by Johnson and colleagues. Reasons for differences are ascribed to the presence of substances with reducing potential other than fructosamine in the serum. PMID:15018152

    Forty-one apparently healthy businessmen and -women and an equal number of government workers matched for age and sex underwent serum cholesterol determinations. The mean serum cholesterol levels of businessmen and -women were significantly higher than those of their government worker counterparts (p < 0.001). The marked increase in the serum cholesterol of the business subjects was attributed to their overindulgence and/or eating habits and lack of physical activity. The cardiovascular risk implications of the high cholesterol value and other risk co-factors such as obesity and alcoholism observed among the business subjects are highlighted. We advise that for communities similar to the one described here, public enlightenment programmes about the health benefits of periodic medical assessment and recreational physical activities are necessary. A further comprehensive study of lipid, lipoprotein and other risk factors in these subjects should be encouraged. PMID:8698110

To search for sequence variants influencing serum levels of CK and LDH, 28.3 million sequence variants identified through whole-genome sequencing of 2,636 Icelanders were imputed into 63,159 and 98,585 people with CK and LDH measurements, respectively. Here we describe 13 variants associating with serum CK and 16 with LDH levels, including four that associate with both. Among those, 15 are non-synonymous variants and 12 have a minor allele frequency below 5%. We report sequence variants in genes encoding the enzymes being measured (CKM and LDHA), as well as in genes linked to muscular (ANO5) and immune/inflammatory function (CD163/CD163L1, CSF1, CFH, HLA-DQB1, LILRB5, NINJ1 and STAB1). A number of the genes are linked to the mononuclear/phagocyte system and clearance of enzymes from the serum. This highlights the variety in the sources of normal diversity in serum levels of enzymes. PMID:26838040

    Klotho is a single-pass transmembrane protein predominantly expressed in the kidney. The extracellular domain of Klotho is subject to ectodomain shedding and is released into the circulation as a soluble form. Soluble Klotho is also generated from alternative splicing of the Klotho gene. In mice, defects in Klotho expression lead to complex phenotypes resembling those observed in dialysis patients. However, the relationship between the level of serum soluble Klotho and overall survival in hemodialysis patients, who exhibit a state of Klotho deficiency, remains to be delineated. Here we prospectively followed a cohort of 63 patients with a mean duration of chronic hemodialysis of 6.7 ± 5.4 years for a median of 65 months. Serum soluble Klotho was detectable in all patients (median 371 pg/mL, interquartile range 309–449). Patients with serum soluble Klotho levels below the lower quartile (<309 pg/mL) had significantly higher cardiovascular and all-cause mortality rates. Furthermore, the higher all-cause mortality persisted even after adjustment for confounders (hazard ratio 4.14, confidence interval 1.29–13.48). We conclude that there may be a threshold for the serum soluble Klotho level associated with a higher risk of mortality. PMID:26604925

    Carbohydrate antigen 72-4 (CA72-4) is a human tumor-associated glycoprotein, commonly used as a tumor marker for diagnosing and predicting outcome in gastric and ovarian cancers. However, the relationship between serum CA72-4 levels and prognosis of pancreatic adenocarcinoma has not been fully elucidated. A total of 113 consecutive locally advanced pancreatic adenocarcinoma patients who underwent intensity-modulated radiation therapy (IMRT) with or without chemotherapy were enrolled in this study. Serum CA72-4 levels were analyzed using immunoenzymometric assays. The association between serum CA72-4 levels and prognosis was evaluated. Serum CA72-4 levels was related with lymph node metastasis (P<0.001). The median overall survival time was 14.0 months for patients with serum CA72-4 normal levels and 10.0 months for the elevated levels (P<0.001). Multivariate analysis identified that Serum CA72-4 concentration was a significant prognostic factor (P<0.001). The hazard ratio (HR) of elevated serum CA72-4 levels compared with normal serum CA72-4 levels was 2.34 (95% confidence interval [CI]: 1.46-3.73), after adjusted for gender and age. Based on this finding, Serum CA72-4 is a potential marker to predict lymph node metastasis and prognosis in pancreatic adenocarcinoma. PMID:25860937

    Using Gamma ray and Fourier Transform Infrared (FTIR) spectroscopic techniques, level of natural radioactivity (238U, 232Th and 40K) and mineralogical characterization of Vaigai River sediments have been analyzed with the view of evaluating the radiation risk and its relation to available minerals. Different radiological parameters are calculated to know the entire radiological characterization. The average of activity concentrations and all radiological parameters are lower than the recommended safety limit. However, some sites are having higher radioactivity values than the safety limit. From the FTIR spectroscopic technique, the minerals such as quartz, microcline feldspar, orthoclase feldspar, kaolinite, gibbsite, calcite, montmorillonite and organic carbon are identified and they are characterized. The extinction co-efficient values are calculated to know the relative distribution of major minerals such as quartz, microcline feldspar, orthoclase feldspar and kaolinite. The calculated values indicate that the amount of quartz is higher than orthoclase feldspar, microcline feldspar and much higher than kaolinite. Crystallinity index is calculated to know the crystalline nature of quartz and the result indicates that the presence of ordered crystalline quartz in the present sediment. The role of minerals in the level of radioactivity is assessed by multivariate statistical analysis (Pearson's correlation and Cluster analysis). The statistical analysis confirms that the clay mineral kaolinite is the major factor than other major minerals to induce the important radioactivity variables such as absorbed dose rate and concentrations of 232Th and 238U.

    Background: Agomelatine modulates brain-derived neurotrophic factor expression via its interaction with melatonergic and serotonergic receptors and has shown promising results in terms of brain-derived neurotrophic factor increase in animal models. Methods: Twenty-seven patients were started on agomelatine (25mg/d). Venous blood was collected and brain-derived neurotrophic factor serum levels were measured at baseline and after 2 and 8 weeks along with a clinical assessment, including Hamilton Depression Rating Scale and Snaith-Hamilton Pleasure Scale. Results: Brain-derived neurotrophic factor serum concentration increased after agomelatine treatment. Responders showed a significant increase in brain-derived neurotrophic factor levels after 2 weeks of agomelatine treatment; no difference was observed in nonresponders. Linear regression analysis showed that more prominent brain-derived neurotrophic factor level variation was associated with lower baseline BDNF levels and greater anhedonic features at baseline. Conclusions: Patients affected by depressive disorders showed an increase of brain-derived neurotrophic factor serum concentration after a 2-week treatment with agomelatine. The increase of brain-derived neurotrophic factor levels was found to be greater in patients with lower brain-derived neurotrophic factor levels and marked anhedonia at baseline. PMID:26775293

    Phthalates are ubiquitous industrial chemicals that have been associated with altered reproductive function in rodents. Several human studies have reported an inverse association between male testosterone and phthalate levels. Our aim was to investigate time to pregnancy (TTP) according to serum levels of diethylhexyl phthalate (DEHP) and diisononyl phthalate (DiNP) metabolites in both partners. In 2002-2004 we enrolled 938 pregnant women and 401 male spouses from Greenland, Poland and Ukraine. Six oxidized metabolites of DEHP and DiNP were summarized for each of the two parent compounds to provide proxies of the internal exposure. We used Cox discrete-time models to estimate fecundability ratios (FR) and 95% confidence intervals (95% CIs) for men and women according to their proxy-DEHP or -DiNP serum levels adjusted for a fixed set of covariates. The FR was slightly elevated among women with high levels of DEHP (FR=1.14, 95% CI 1.00;1.30) suggesting a shorter TTP in these women. The FR was unrelated to DiNP in women, whereas the results for men were inconsistent pointing in opposite directions. First-time pregnant women from Greenland with high serum DiNP levels had a longer TTP. This study spanning large contrast in environmental exposure does not indicate adverse effects of phthalates on couple fecundity. The shorter TTP in women with high levels of DEHP metabolites is unexplained and needs further investigation. PMID:25786246

    Preeclampsia is a serious pregnancy complication characterized by hypertension, proteinuria with or without pathological edema. According to some studies, serum uric acid lacks sensitivity and specificity as a diagnostic tool whereas another group of the researchers indicated uricemia as a predictor of preeclampsia in pregnant ladies. The present study was designed to assess whether serum uric acid can be used as a biochemical indicator or not in preeclamptic patients. Pre-eclamptic patients admitted in Nepal Medical College Teaching Hospital from June 2012 to June 2013 were included in this study. Age matched normal healthy pregnant ladies served as control. The record of their blood pressure and serum uric acid level was evaluated. Results showed significantly high blood pressure [SBP 149.42±12.35 vs 109.00±7.93 mm Hg; DBP 96.85±8.32 vs 72.5±7.10 mm Hg], and serum uric acid level [6.27±1.37 vs 4.27±0.61 mg/dl] in pre-eclamptic patients compared to their healthy counterparts. Uric acid is a terminal metabolite of the degradation of nucleotides, which increases their blood levels in patients with preeclampsia increasing its synthesis by damage and death of trophoblastic cells and proliferation. Uricemia in preeclampsia likely results from reduced uric acid clearance from diminished glomerular filtration, increased tubular reabsorption and decreased secretion. Results of the present study indicated association of elevated serum uric acid level with preeclampsia which could be used as a biochemical indicator of preeclampsia in pregnant women. PMID:25799807

    We have previously reported that serum pepsinogen (PG) can quantify the level of gastric mucosal atrophy, and that H. pylori eradication reduces cancer development in subjects with mild atrophy identified by serum PG levels. The aim of this study was to elucidate the predictive ability of serum PG levels for the development of metachronous gastric cancer (MGC) after endoscopic resection (ER) of primary cancer in association with H. pylori eradication. A retrospective chart review was performed, and 330 patients who underwent ER for initial early gastric cancer were enrolled. Presence or absence of H. pylori, serum PG levels, and endoscopic atrophy at ER were evaluated. H. pylori eradication was performed at the patient's request after ER. The incidence of MGC in these patients was analyzed. Of 330 patients, 47 developed MGC. Endoscopic extensive atrophy was observed more frequently in patients with MGC (p = 0.001). Although PG I or PG II alone did not significantly differ according to development of MGC, the proportion of PG I/II ≤ 3.0, which is one of the criteria of PG test-positive, was significantly higher in patients with MGC (83 vs. 69%, p = 0.04). H. pylori eradication after ER did not affect MGC development (p = 0.2). On multivariate analysis, serum PG I/II ratio ≤ 3.3 was significantly associated with the development of MGC (hazard ratio: 3.66, 95% confidence interval: 1.47-12.25, p = 0.004). The risk of MGC after ER could be quantitatively predicted by the PG I/II ratio regardless of H. pylori status. PMID:27083518

    Background Cardiovascular disease (CVD) is a leading cause of death worldwide, and the number of people at risk is continuously growing. New methods for early risk prediction are therefore needed to actuate prevention strategies before the individuals are diagnosed with CVD. Several studies report that aerobic fitness level, measured as maximal oxygen uptake (VO2max), is the single best predictor of future CVD mortality in healthy people. Based on this, we wanted to study differences between healthy individuals with a large difference in VO2max-level to identify new biomarkers of low aerobic fitness that may also have potential as early biomarkers of CVD risk. Methodology/Principal Findings Serum samples from 218 healthy individuals with a low VO2max (n = 108, 63 women) or high VO2max (n = 110, 64 women) were analysed with MR metabolomics. In addition, standard clinical-chemical analyses for glucose, lipids, liver enzymes, micro-CRP, and colorimetric analysis on circulating choline were performed. Individuals in the low VO2max-group had increased serum levels of free choline, decreased phosphatidylcholine, increased glucosę and decreased unsaturated fatty acids compared to the individuals in the high VO2max–group. Conclusions/Significance Aerobic fitness dependent differences in serum levels of free choline and phosphatidylcholine are observed. They should be further studied as potential early markers of CVD risk. PMID:22860113

    Study Design An in vivo dosing study of vitamin D in a rat posterolateral spinal fusion model with autogenous bone grafting. Rats randomized to four levels of Vitamin D adjusted rat chow, longitudinal serum validation, surgeons/observers blinded to dietary conditions, and rats followed prospectively for fusion endpoint. Objective To assess the impact of dietary and serum levels of Vitamin D on fusion success, consolidation of fusion mass, and biomechanical stiffness after posterolateral spinal fusion procedure. Summary of Background Data Metabolic risk factors, including vitamin D insufficiency, are often overlooked by spine surgeons. Currently there are no published data on the causal effect of insufficient or deficient vitamin D levels on the success of establishing solid bony union after a spinal fusion procedure. Methods 50 rats were randomized to four experimentally controlled rat chow diets: normal control, vitamin D-deficient, vitamin-D insufficient, and a non-toxic high dose of vitamin D, four weeks prior to surgery and maintained post-surgery until sacrifice. Serum levels of 25(OH)D were determined at surgery and sacrifice using radioimmunoassay. Posterolateral fusion surgery with tail autograft was performed. Rats were sacrificed 12 weeks post-operatively and fusion was evaluated via manual palpation, high resolution radiographs, μCT, and biomechanical testing. Results Serum 25(OH)D and calcium levels were significantly correlated with vitamin-D adjusted chow (p<0.001). There was a dose dependent relationship between vitamin D adjusted chow and manual palpation fusion with greatest differences found in measures of radiographic density between high and deficient vitamin D (p<0.05). Adequate levels of vitamin D (high and normal control) yielded stiffer fusion than inadequate levels (insufficient and deficient) (p<0.05). Conclusions Manual palpation fusion rates increased with supplementation of dietary vitamin D. Biomechanical stiffness, bone volume and

    Background Menopausal hormone therapy increases mammographic density. We determined whether increases in serum estrone sulfate (E1S) levels during menopausal hormone therapy predict increased mammographic density. Methods We measured percent mammographic density and serum E1S levels in 428 participants of the Postmenopausal Estrogen/Progestin Interventions study who were randomly assigned to daily conjugated equine estrogen (CEE) 0.625 mg alone, CEE + daily medroxyprogesterone acetate (MPA) 2.5 mg, CEE + cyclical MPA (10 mg days 1-12 per 28-day cycle), or CEE + cyclical micronized progesterone (10 mg days 1-12). Serum E1S levels were determined by RIA. Information about covariates was determined by annual questionnaire. Using linear regression, we determined the association between change in E1S level from baseline to 12 months and change in percent mammographic density (by semiquantitative interactive threshold method). Results After controlling for baseline mammographic density, age, body mass index, alcohol intake, parity, smoking, ethnicity, physical activity, and age at first pregnancy, mammographic density increased by 1.3% for every 1 ng/mL increase in E1S level (P < 0.0001). The association between change in E1S level and change in mammographic density differed by treatment group (greater effect in CEE + cyclical MPA group versus CEE group; P = 0.05). After controlling for treatment group, change in the ratio of E1S to E1 was also positively associated with change in mammographic density. Conclusions Increases in serum E1S levels during menopausal hormone therapy are associated with increases in mammographic density. The relative contribution of E1S and E1 to stimulation of breast tissue awaits further elucidation. PMID:18628419

    Purpose: The prognostic significance of human chorionic gonadotropin (HCG) level in central nervous system germinoma remains controversial. The purpose of this study was to compare clinical characteristics and prognosis of germinoma patients with normal and high HCG titers in the serum. Methods and Materials: We undertook a multi-institutional retrospective analysis of 103 patients with central nervous system germinoma whose serum HCG and/or {beta}-HCG level had been measured before treatment between 1984 and 2002. All patients had been treated with radiation therapy either alone (n = 66) or in combination with chemotherapy (n = 37) with a median dose of 47.8 Gy. Results: HCG and/or {beta}-HCG level in the serum was high in 39% of all patients. The proportion of HCG-producing tumors was higher in the lesions at the basal ganglia than in the lesions at the other sites. No correlation was found between tumor size and HCG level, but there seemed to be a weak correlation between size and {beta}-HCG. The 5- and 10-year survival rates were 96% and 94%, respectively, in both patient groups with normal and high HCG (p = 0.99). The 5- and 10-year relapse-free survival rates were 87% and 82%, respectively, in patients with normal HCG level and were both 87% in patients with high HCG (p = 0.74). Also, no other patient-, tumor-, or treatment-related factors seemed to influence the prognosis of the patients. Conclusion: Serum HCG level does not seem to influence patient prognosis when treated with sufficient doses of radiation. Relationship between tumor size and site and HCG level should be investigated further.

    Accelerated atherosclerosis is the major cause of mortality in patients on chronic hemodialysis (HD). The aim of this study was to evaluate the relation between coenzyme Q10 (CoQ10) levels and coronary flow reserve (CFR) in HD patients as an indicator of atherosclerosis. Seventy-one chronic HD patients and 65 age- and sex-matched healthy individuals were included in the study. Plasma CoQ10 levels were performed by high-performance liquid chromatography measurements. CFR was assessed by transthoracic Doppler echocardiography. Serum CoQ10 levels (1.36 ± 0.43 vs. 2.53 ± 0.55, P < 0.001) and CFR values (1.73 ± 0.11 vs. 2.32 ± 0.28, P < 0.001) were significantly lower in HD patients compared with controls. There was a significant positive correlation between CFR and serum levels of CoQ10 (r = 0.669, P < 0.001). A linear regression analysis showed that serum levels of CoQ10 were still significantly and positively correlated with CFR (regression coefficient = 0.235, P < 0.001). Our data have demonstrated that HD patients exhibit decreased plasma CoQ10 levels and CFR values. The study also showed for the first time that serum CoQ10 levels independently predict CFR in HD patients. PMID:23185999
