1982-01-01

A commercial test kit for radioimmunologic proof of myoglobin in serum was tested with regard to its specificty, sensitivity, precision, reproducibility, recovery and use in the diagnosis and therapy of musculoskeletal diseases. In the serum of 164 healthy control persons (age: 2-79 years) the individual myoglobin concentrations ranged from 4 to 60 ng/ml. Among 300 patients with muscular diseases extreme myoglobinaemia in acute rhabdomyolysis, polymyositis and dermatomyositis and different progressive muscular dystrophies could be detected. Slightly increased myoglobin concentrations could be proved in a number of patient with amyotrophic lateral sklerosis, neural muscular atrophy and in all cases of spinal muscular atrophy of the Kugelberg-Welander type. Confirmed DMD patients exhibited in about 80% of the cases hypermyoglobinaemia, and about 11% of 43 possible DMD patients showed an increase in myoglobin. Taking acute rhabdomyolysis and myositis as an example, it was found that myoglobin correlates well with the clinical course of these diseases and permits safe inferences as to the efficiency of the therapy chosen.

Full Text Available A case-cohort study, within a multi-country trial of antiretroviral therapy (ART efficacy (Prospective Evaluation of Antiretrovirals in Resource Limited Settings (PEARLS, was conducted to determine if pre-ART serum selenium deficiency is independently associated with human immunodeficiency virus (HIV disease progression after ART initiation. Cases were HIV-1 infected adults with either clinical failure (incident World Health Organization (WHO stage 3, 4 or death by 96 weeks or virologic failure by 24 months. Risk factors for serum selenium deficiency (<85 μg/L pre-ART and its association with outcomes were examined. Median serum selenium concentration was 82.04 μg/L (Interquartile range (IQR: 57.28–99.89 and serum selenium deficiency was 53%, varying widely by country from 0% to 100%. In multivariable models, risk factors for serum selenium deficiency were country, previous tuberculosis, anemia, and elevated C-reactive protein. Serum selenium deficiency was not associated with either clinical failure or virologic failure in multivariable models. However, relative to people in the third quartile (74.86–95.10 μg/L of serum selenium, we observed increased hazards (adjusted hazards ratio (HR: 3.50; 95% confidence intervals (CI: 1.30–9.42 of clinical failure but not virologic failure for people in the highest quartile. If future studies confirm this relationship of high serum selenium with increased clinical failure, a cautious approach to selenium supplementation might be needed, especially in HIV-infected populations with sufficient or unknown levels of selenium.

Objective: To study the serum HA and LN level in patients with pulmonary tuberculosis and their response to therapy. Methods: Serum HA and LN levels were measured with RIA in: (1) 42 patients with active pulmonary tuberculosis both before and after 2 months' therapy, (2) 40 patients with non-active pulmonary TB and 330 controls. Results: The serum HA and LN level in patients with active pulmonary tubemulosis were significantly higher than those in controls (P < 0.01 ), while no significant difference could Be found Between the levels in patients with non-active pulmonary tuberculosis and controls. The serum HA and LN level in patients with active pulmonary tuberculosis dropped after therapy, but were still higher than those in controls. Significant correlation could Be found between HA and LN levels (P<0.01). The HA and LN levels were positively correlated with severity of the disease, ESR and CRP contents. Conclusion: The measurement of serum HA and LN is valuable for early diagnosis, monitoring development and assessment of therapeutic effect in patients with pulmonary tubemulosis. (authors)

Full Text Available In this study the effect of rifampin on serum inhibitory and serum bactericidal titres was examined. Sera were prepared from pooled human serum to contain vancomycin (10 mg/L, cloxacillin (5 mg/L or rifampin (1 mg/L, and the combinations cloxacillin/rifampin and vancomycin/rifampin. These five sera were tested by a microtitre method for serum inhibitory power and serum bactericidal titre against 11 strains of Staphylococcus aureus. A 48 h incubation period was required to detect full colony growth for subculture plates. It was found with all strains that the effect of the addition of rifampin to the other two antibiotics was to increase the serum inhibitory power, lower the serum bactericidal titre, increase the inhibitory/cidal ratio, and slow colony growth on subculture. In the clinical part of the study it was shown that only three of 38 sera (8% from patients receiving betalactam or vanomycin but not rifampin gave an inhibitory/cidal ratio greater than 8, but that nine of 10 sera (90% from patients receiving rifampin in addition to betalactam or vancomycin gave a ratio greater than 8 (P<0.001. The study verified that the effect of rifampin in serum was to increase inhibitory power and decrease bactericidal titre. The clinical significance of these results is not known and it is suggested that a high ratio of inhibitory to bactericidal titre in the presence of rifampin is to be expected, and that a low bactericidal titre under these circumstances is not necessarily an indication to modify therapy.

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

The aim of the present study was to evaluate the cerebrospinal fluid (CSF)/serum leptin ratio during pharmacological therapy for obesity with centrally and peripherally acting drugs. Thirty-one obese women (mean age, 32.3 +/- 10 yr; body mass index, 38.2 +/- 5.2 kg/m(2); body fat, 43.3 +/- 5.4%) were studied before and 2 months after a weight loss program consisting of a balanced diet (1200 kcal/d) plus drug therapy. The patients were randomly assigned into three study groups: group I, fenproporex 25 mg/d (n = 10); group II, sibutramine 10 mg/d (n = 10); and group III, orlistat 120 mg tid (n = 11). Body fat, measured by dual-energy x-ray absorptiometry, and serum and CSF concentrations of leptin were examined at baseline and 2 months after therapy. At baseline, clinical and biochemical characteristics of the groups were similar. All of the women lost weight, approximately 7.0% of their initial body weight, and the reduction was not different among the groups. Serum leptin fell significantly after 2 months in all groups, and the decline was proportional to the reduction in body fat, because leptin levels adjusted for body fat did not change after treatment. CSF leptin levels showed a significant decrease after 2 months in all groups, and this decline was higher on group III compared with group I (P = 0.006). After therapy, the CSF/serum leptin ratio did not change in group I (1.57 +/- 0.3 to 1.72 +/- 0.62%) and group II (1.78 +/- 1.01 to 1.69 +/- 1.27%), whereas it declined significantly in group III (1.65 +/- 0.43 to 1.09 +/- 0.47%; P obese women treated during 2 months with orlistat, whereas this ratio did not change in this period of time in obese women treated with fenproporex and sibutramine.

TT3, FT3 and FT4 concentrations were measured in 28 patients with hyperthyroidism before and during therapy with radioiodine. In addition, in some patients serum thyroglobulin was evaluated, too. Only in the patients with immunogenic hyperthyroidism FT3, FT4 and serum TG were elevated significantly within the first two days after radioiodine application. In the residual patients with diffuse autonomy, autonomous adenoma, and multifocal autonomy during the whole time of investigation there was no significant increase of the respective values. From these data it can be deducted that hyperthyroid storm is more likely to be provoked in patients with immunogenic hyperthyroidism compared to thyroidal autonomy. (orig.) [de

Goeckerman's therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. Pentraxin 3 (PTX3) is a newly identified acute phase reactant with non redundant functions in innate immunity. PTX3 has been shown to be a reliable prognostic marker in patients with various inflammatory disorders including rheumatoid arthritis, vasculitis, and psoriasis. The aim of this study was to evaluate the influence of Goeckerman's therapy of psoriasis on levels of two pentraxins: long pentraxin PTX3 and C reactive protein in 49 patients with chronic plaque psoriasis. CRP was assessed by immunonephelometry on IMMAGE 800 (Beckman, USA). PTX3 was detected using sandwich ELISA detection set (Alexis Biochemicals, Switzerland). The serum levels of both parameters (expressed as average {+-} 1 SD) were significantly diminished after GT. The level of PTX3 dropped from 1.92 {+-} 0.72 ng/ml before GT to 1.66 {+-} 0.58 ng/ml after GT (P = 0.0396) and the level of CRP fell from 4.64 {+-} 3.93 mg/l to 1.66 {+-} 0.58 mg/l (P {lt} 0.0001). Comparing to healthy controls, the serum levels of both parameters before GT were significantly higher than those found in healthy blood donors and remained significantly increased after GT. Increased serum concentrations of pentraxin 3 and CRP are alleviated by GT in patients with psoriasis.

This study was undertaken to evaluate long-term effects of spironolactone on basal serum estrone, estradiol, testosterone, LH and prolactin concentrations in hypertensive male patients. Serum prolactin response to TRH was also evaluated. There were two groups, (a) six males with essential hypertension given 75 - 150 mg spironolactone daily for 12 weeks, and (b) two males with idiopathic hyperaldosteronism given 300 mg daily for over 40 weeks. In the conventional-dosage group, serum estrone concentrations significantly increased (P < 0.01) at 12 weeks serum estradiol gradually increased but not statistically significantly (P < 0,2). Basal serum testosterone, LH and prolactin concentrations did not show significant changes. There was no increase in serum prolactin response to TRH. In the high-dosage group, serum estrone levels remained high, and serum estradiol increased with the development of gynaecomastia. Serum testosterone, LH and prolactin concentrations showed no marked changes. The elevations in circulating oestrogens could well explain the oestrogenic side-effects of spironolactone treatment.

Full Text Available Aim To assess serum HGF concentration in individuals with bipolar disorder and investigate the efficacy of zinc therapy on these levels. Subjects and Methods Serum from 35 individuals diagnosed with bipolar disorder and 19 age and gender similar controls were tested for HGF concentration using ELISAs, and copper and zinc plasma levels using inductively-coupled plasma-mass spectrometry. Results HGF serum levels of individuals with bipolar disorder were significantly lower than age and gender similar controls ( P = 0.0021. HGF serum concentration was significantly lower in Bipolar patients pre-therapy ( P = 0.0009 and HGF levels normalized post-therapy. Zinc levels in these same individuals also normalized ( P = 0.0046 and patient's perceived severity of Bipolar symptoms significantly decreased after therapy ( P = 0.0003. We also found a significant direct correlation between Zinc and HGF serum concentration in the bipolar patients ( P = 0.04. Discussion These results suggest an association between low HGF levels and bipolar disorder and also demonstrate that zinc therapy may be associated with the normalization of HGF levels and decrease in severity of disease.

To investigate dynamic change of serum receptor and antibody of thyrotrophic anti- body (TRAb) and its prognosis value after a one-off successful therapy on Graves disease with 131 I, 257 Graves disease patients were treated with one dose of 131 I therapy. 175 of them with average age of 40 (43 male and 132 female patients) were cured. The 131 I activity given to patients was 207.2±66. 6 MBq. The serum levels of TRAb were determined once every three months before and after 131 I therapy. The results showed that the serum TRAb levels in all patients were positive before 131 I therapy. The serum TRAb levels in 60. 6% of patients were raised once, and then reduced to normal, The serum levels of TRAb in 16.0% of patients were remained high or reduce slowly, and the clinical symptom was improved slowly, but these patients didn't recrudesce. The TRAb levels in 9.7% of patients decreased continually, their prognosis was well. The TRAb levels in 13.7% of patients were raised twice after the therapy, and appear hypothyroidism. The detection of dynamic changes of serum TRAb levels in Graves disease patients may be useful in assessing prognosis after 131 I therapy. (authors)

Immunotherapy of murine leukemia. Efficacy of passive serum therapy of Friend leukemia virus-induced disease in immunocompromised mice

Genovesi, E.V.; Livnat, D.; Collins, J.J.

Previous studies have demonstrated that the passive therapy of Friend murine leukemia virus (F-MuLV)-induced disease with chimpanzee anti-F-MuLV serum is accompanied by the development of host antiviral humoral and cellular immunity, the latter measurable in adoptive transfer protocols and by the ability of serum-protected mice to resist virus rechallenge. The present study was designed to further examine the contribution of various compartments of the host immune system to serum therapy itself, as well as to the acquired antiviral immunity that develops in serum-protected mice, through the use of naturally immunocompromised animals [e.g., nude athymic mice and natural killer (NK)-deficient beige mutant mice] or mice treated with immunoabrogating agents such as sublethal irradiation, cyclophosphamide [Cytoxan (Cy)], cortisone, and 89 Sr. The studies in nude mice indicate that while mature T-cells are not needed for effective serum therapy, they do appear to be necessary for the long-term resistance of serum-protected mice to virus rechallenge and for the generation of the cell population(s) responsible for adoptive transfer of antiviral immunity. Furthermore, this acquired resistance is not due to virus neutralization by serum antibodies since antibody-negative, Cy-treated, serum-protected mice still reject the secondary virus infection. Lastly, while the immunocompromise systems examined did effect various host antiviral immune responses, none of them, including the NK-deficient beige mutation, significantly diminished the efficacy of the passive serum therapy of F-MuLV-induced disease

To evaluate the role of umbilical cord serum (UCS) and autologous serum (AS) therapy in reepithelialization of corneal graft after keratoplasty in a randomized controlled trial. A total of 105 eyes with epithelial defect (ED) after keratoplasty (penetrating keratoplasty-67 and anterior lamellar keratoplasty-38) on the first postoperative day were included in the study. The eyes were randomized into three groups: UCS (n=35), AS (n=35), and artificial tears (AT) (n=35). All patients received standard postoperative medical therapy. The primary outcome measure was time to epithelialization, and secondary outcome measures were best-corrected visual acuity and graft clarity. The ED healed completely in 103 eyes. The mean time for complete reepithelialization was 2.5±2.1, 3.1±2.2, and 4.5±1.4 days in UCS, AS, and AT groups, respectively. The mean percentage decrease in the size of the ED was significantly better in the UCS and AS groups as compared with the AT group (P=0.001). The rate of reepithelialization was comparable between the AS and UCS groups (P=0.3). On bivariate analysis, significant correlation was found between the mean size of postoperative ED, grade of the donor cornea (P=0.001), and the presence of preoperative ED (P=0.001). No complications were associated with the use of serum therapy. Most of the cases of postkeratoplasty corneal ED can be managed with AT only. The serum therapy (AS/UCS) helps in the faster reepithelialization of postkeratoplasty ED as compared with AT and may be considered as a treatment option for early epithelial healing.

The aim of this study was to evaluate the efficacy of treatment with mud pack in knee osteoarthritis (OA) and to determine whether mud pack effects serum levels of YKL-40 and high-sensitivity C-reactive protein (hsCRP) which are reported to be biological markers for articular damage or inflammation in patients with OA. Forty-four patients with the diagnosis of knee OA assigned into two groups were treated with local natural mineral-rich mud pack or hot pack. Treatments were applied for 6 days a week for 2 weeks as a total of 12 sessions. Patients were assessed at baseline, post-treatment, and 3 months after the treatment. VAS, range of motion, 15-m walking time, WOMAC index, Nottingham Health Profile, serum YKL-40, and hsCRP levels were the outcome measures. Pain intensity and joint stiffness decreased in both groups at all follow-ups. Physical activity status was found to persist for 3 months after treatment only in mud pack group. Serum mean YKL-40 and hsCRP levels of the patients were higher compared to healthy control group. Serum YKL-40 level increased significantly only in hot pack group 3 months after the treatment (P 0.05). Mud pack and hot pack therapy were both demonstrated to be effective in symptomatic treatment of knee OA until the end of the 2-week treatment period, whereas only mud pack therapy was shown to be effective in functional status over time. In the hot pack group, increased serum YKL-40 level 3 months after the treatment might indicate persistence of cartilage degradation. Maintenance of YKL-40 level in mud pack therapy seems to slow down the progression of knee OA.

Full Text Available Background. Goeckerman’s therapy (GT of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. Disturbances in angiogenic activity are characteristic for the immunopathogenesis of psoriasis. The aim of study was to evaluate the influence of GT of psoriasis on proinflammatory and angiogenic activities expressed as changes in levels of endoglin (CD105. Methods. Serum levels of a soluble form of endoglin were measured in peripheral blood samples of 38 patients with psoriasis before and after therapy. Sixty three otherwise healthy blood donors serve as a control group. The efficacy of GT was expressed as changes in Psoriasis Area and Severity Index (PASI. Results. PASI score was significantly diminished by GT (p<0.001. Serum levels of soluble CD105 were significantly diminished after GT. The serum level of soluble CD105 dropped from 7.85 ± 2.26 ng/ml before therapy to 7.01 ± 1.71 ng/ml after therapy (p= 0.0002. Compared to serum levels of soluble CD105 in healthy blood donors, serum levels of soluble CD105 in patients before GT were significantly higher (p<0.001 and remained elevated after therapy (p<0.001. Angiogenic activity expressed as serum endoglin is diminished in patients with psoriasis treated by GT.

Natriuretic peptides have been associated with dyslipidemia. As a physiological activator of natriuretic peptides, corin might also be associated with dyslipidemia. However, this association has not yet been studied in Chinese populations. Serum soluble corin and blood lipid profiles were determined for 2496 participants aged above 30y. A logistic regression model was applied to evaluate the association between serum soluble corin and dyslipidemia. Serum soluble corin was significantly increased in participants with dyslipidemia in both men (Pdyslipidemia positively increased with increasing levels of serum soluble corin in men (P for trend=0.011) and women (P for trend=0.043). Participants with a high corin level were more likely to have dyslipidemia than those with a low corin level in men (OR, 95% CI: 1.45, 1.07-1.97) and women (OR, 95% CI: 1.33, 1.04-1.70). Serum soluble corin was significantly and positively associated with dyslipidemia. Our findings suggested that serum soluble corin may be a marker or risk factor for dyslipidemia.

The predictive value of interleukin-35 (IL-35) on efficacy of immunosuppressive therapy (IST) in aplastic anemia (AA) has not been well investigated. The aim of the study was to evaluate the association between serum IL-35 level and response to IST in pediatric AA. A total of 154 children with AA and 154 controls were included between January 2012 and December 2013. Blood and bone marrow fluid specimens were collected. Serum level of IL-35 was determined by enzyme-linked immunosorbent assay. Patients were treated with IST, and response to therapy was evaluated during 180-day follow-up period after starting therapy. Serum levels of IL-35 at admission decreased significantly in patients compared with that in controls (10.9 ± 5.5 pg ml -1 and 45.3 ± 8.8 pg ml -1 , p < 0.001). After starting IST, serum levels of IL-35 in patients recovered 30.7 ± 9.7 pg ml -1 in the first 28 days (p < 0.001). During the follow-up period, increased range of serum IL-35 level ≥30.7 pg ml -1 in the first 28 days was associated with effective response to therapy (odds ratio 7.97, 95% confidence interval 3.82-16.79). In addition, Fas/FasL protein expression in bone marrow mononuclear cells dropped significantly in the same group of patients in the first 28 days (p < 0.05). The study revealed that post-therapeutic recovery of circulating IL-35 concentration might be an independent predictor for effective response to IST in pediatric AA. Moreover, apoptosis might be involved in such a forecasting process.

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

Serum thyroxine (T4) concentrations were measured before treatment in all cats, at 12-hour intervals after treatment in 10 cats, and at 48-hour intervals after treatment in 21 cats. Serum T4 concentrations also were measured one month after 131 I therapy in 29 cats. Activity of 131I administered was 1.5 to 6.13 mCi, resulting in a dose of 20,000 rads to the thyroid. Serum T4 concentrations before 131 I administration were 5.3 to 51.0 micrograms/dl, with a median T4 concentration of 11.0 micrograms/dl. Serum T4 decreased most rapidly during the first 3 to 6 days after treatment. Sixteen cats (55%) had normal serum thyroxine concentrations by day 4 after 131I administration, and 23 cats (74%) were euthyroxinemic by day 8 after treatment. One month after administration of 131I, the 29 cats evaluated were clinically improved, and 24 (83%) of the 29 cats evaluated had normal serum T4 concentrations, 3 cats (10%) remained hyperthyroxinemic, and 2 cats (7%) were hypothyroxinemic. Therefore, administration of 131I was a safe and effective method to quickly decrease serum T4 concentrations in hyperthyroid cats

The aim of this study is to investigate the effects of serum high-sensitivity C-reactive protein (hsCRP) and the pathological changes in the carotid artery after periodontal mechanical therapy with local and systemic drugs in SD rats with chronic periodontitis (CP) associated with atherosclerosis (As). Thirty-five SD rats were randomly divided into two groups: control group (group A) and CP+As group (group B). Group B was further divided into the natural process group (B1), the periodontal mechanical treatment group (B2), the periodontal mechanical treatment plus local drugs group (B3), and the periodontal mechanical treatment plus local and systemic drugs group (B4). Each group comprised seven rats. Serum hsCRP levels were evaluated at baseline 1 week after the first periodontal therapy and 1, 3, and 5 weeks after the second periodontal therapy by enzyme linked immunosorbent assay (ELISA). The pathological lesion in the carotid artery plaque was stained with hematine and eosin. The levels of serum hsCRP in group B1 increased gradually as time passed and became significantly higher than that of the other groups five weeks after periodontal therapy (P periodontal therapy. After that, the levels of serum hsCRP decreased gradually but were still higher than that of group A (P periodontal therapy (P periodontal mechanical treatment results in acute, short-term, systemic inflammation and might increase the risk of atherosclerosis in SD rats. However, the levels of serum hsCRP decreased gradually 3 to 5 weeks after therapy. With periodontal mechanical treatment, the benefits of local and systemic drugs are associated with improvement in atherosclerotic lesion progression.

Matrix metalloproteinases are involved in neuroinflammatory processes, which could underlie depression. Serum levels of MMP-9 and MMP-2 in depressed patients are significantly altered following electroconvulsive therapy, but an association between altered matrix metalloproteinases after successful ECT and possible relapse has yet to be investigated. Serum was obtained twice, before and immediately after a course of electroconvulsive therapy, from 38 depressed patients. Serum was also collected, once, from two groups of age- and gender-matched healthy controls, 40 volunteers in each group. Possible associations between levels of matrix metalloproteinases and relapse during a 1-year follow-up period were analyzed. Excluding patients who did not respond to electroconvulsive therapy and patients lost to follow-up, data from 28 patients were evaluated. Eighteen of the patients (64.3%) relapsed within 1 year. In the group that did not relapse, serum levels of MMP-9 were significantly decreased after a course of electroconvulsive therapy, but not in the group that relapsed. No association between MMP-2 and relapse was observed. The degree of change in serum MMP-9 change could be associated with relapse following electroconvulsive therapy in depressed patients. © The Author 2017.

Monitoring renal function is important in imatinib-treated patients with chronic myeloid leukemia because serum creatinine may increase during the course of therapy. The mechanism of this increase and its reversibility on treatment cessation have never been investigated. We retrospectively analyzed data from imatinib-treated patients explored in our renal physiology unit with measurement of glomerular filtration rate (urinary clearance of (51)CrEDTA) and of urinary clearance and tubular secretion of creatinine. Results were compared with those of controls matched for measured glomerular filtration rate, age, gender, and ethnicity. We also analyzed variations of serum creatinine before and during imatinib cessation and after imatinib resumption in patients enrolled in imatinib discontinuation studies. In 4 imatinib-treated patients who underwent thorough renal exploration, the part of creatinine clearance due to tubular secretion was negligible (2.4, 3.1, -1.3, and 2.8 mL/min) and significantly lower than that measured in their respective controls (17.7 ± 5.6, 43.0 ± 18.0, 23.1 ± 6.7, and 18.6 ± 5.6 mL/min, P creatinine tubular secretion (20.3 vs. 17.9 ± 5.2 mL/min in the control population, P = .2). In 15 patients of imatinib discontinuation studies, a median decrease in serum creatinine of 17.9% was observed after imatinib cessation. Resumption of treatment in 6 patients led to a median increase in serum creatinine of 18.8%. Imatinib completely blunts tubular secretion of creatinine, a previously unreported pharmacologic property. This inhibition increases serum creatinine independently of any glomerular dysfunction and is fully reversible on imatinib cessation. Copyright © 2016 Elsevier Inc. All rights reserved.

With the use of the method of fluorescent probes the condition of the centers of linkage of serum albumin in healthy women and in the cancer patients, passing a course of beam therapy, is analyzed at different modes. It is shown that general concentration of albumin in healthy persons and cancer patients are in the limits of normal values, however parameters of effective concentration of albumin, reserve of albumin linkage and toxicity index of patients statistically, for certain, differ in comparison with those in the control group. Carrying out the beam therapy course both split and not split promotes an increase of values of toxicity index. (authors)

Full Text Available Abstract Background Matrix metalloproteinases (MMPs, together with their tissue inhibitors (TIMPs, remodel extracellular matrix under physiological and pathological conditions and are implicated in pathogenesis of cardiovascular diseases, cancer and in chronic inflammation. We have endeavoured to assess whether concentrations of MMPs, TIMPs, and anti-inflammatory adiponectin are altered by pharmacological treatment of acute thyrotoxicosis or by radioiodine therapy (RIT. Material and methods We measured serum concentrations of MMP-2, MMP-9, TIMP-1, TIMP-2, and adiponectin, TSH, free T4 (FT4 and free T3 (FT3 in 15 patients (4 males, age (years 51.8±15.3 (mean±SD with hyperthyroidism treated with thiamazole (Group 1 and in 20 subjects (2 males, treated for thyrotoxicosis with radioiodine, age 52.3±12.4 (Group 2, where blood samples were taken before RIT, visit 1 (V1, seven days post RIT, visit 2 (V2, and two to three months post RIT, visit 3 (V3. Results In Group 1 there was no significant change in concentrations of MMP-2, MMP-9, TIMP-1, TIMP-2 or adiponectin, despite a fall in FT4 and FT3 (8.74±4.79 pg/ml vs 3.54±2.40 pg/ml, for FT3, and 4.48 ±2.21 ng/ml vs 1.02±1.07 ng/ml, for FT4, p4 and FT3 from 24.4±15.4 pmol/l (V1 to 14.7±10.6 pmol/l (V3, and from 10.0±5.65 (V1 to 6.1±4.8 pmol/l (V2, p4 and FT3, respectively. Conclusions Radioiodine therapy of thyrotoxicosis does not alter serum MMP-2, MMP-9 or TIMP-1 concentrations either acutely or after about three months of observation. An increase in serum adiponectin might reflect favourable effects of radioiodine administration on cardiovascular risk factors, while an increase in TIMP-2 (principal MMP-2 inhibitor might lead to a decrease in free MMP-2 concentrations.

Data on whether periodontal therapy affects serum CRP levels are inconclusive. The aim of this study was to determine if nonsurgical periodontal therapy has any effect on CRP and serum lipid levels in patients with advanced periodontitis. Thirty-six systemically healthy patients, ≥ 40 years of age and with advanced periodontitis, were recruited for the study. Patients were randomized consecutively to one of two groups: the treatment group (n = 18) or the control group (n = 18). Treated subjects received nonsurgical periodontal therapy, which included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers [C-reactive protein (CRP) and the lipid profile] were measured at baseline and 3 mo after periodontal therapy. Nonsurgical periodontal therapy in the treatment group resulted in a significant reduction in the serum CRP level. The average CRP level decreased from 2.3 mg/dL at baseline to 1.8 mg/dL (p periodontal therapy. The average reduction (95% confidence interval) in CRP was 0.498 (95% confidence interval = 0.265-0.731). In the treatment group, the reduction in CRP was significantly, linearly and directly correlated with the reduction in the plaque index, the gingival index and the percentage of sites with pocket depth ≥ 7 mm (Pearson correlation coefficient = 0.746, 0.425 and 0.621, respectively). Nonsurgical periodontal therapy had no effect on the lipid parameters. This study demonstrated that nonsurgical periodontal therapy results in a significant reduction in the serum CRP level. The effect of this outcome on systemic disease is still unknown. © 2011 John Wiley & Sons A/S.

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

The effect of radioiodine ( 131I ) in Graves disease (GD) is probably due to the direct physical destruction of thyrocytes by beta radiation, and by the indirect action through stimulation of apoptosis in these cells. The aim of our study was to investigate the changes in serum concentrations of sFas and sFasL as stimulators of apoptosis, and Bcl-2 as an inhibitor of apoptosis in patients with GD following 131I administration. The study was performed on 30 patients with GD (29 female and 1 male aged 25-45). All patients were euthyroid (biochemical and clinical) prior to radioiodine therapy. The target absorbed dose ranged between 90 and 160 Gy. We assessed markers of apoptosis and hormone concentrations (fT3, fT4 and TSH) in the following manner: before 131I administration, then two weeks, one month, two, three, four, and five months after 131I administration. After four months, the concentrations of sFas and sFasL rose by 50% and decreased during the next month. Pretherapeutic concentrations of Bcl-2 were elevated, and peaked two weeks after ingestion, showing a gradual decrease with time. We found a significant increase in serum TSH, and a decrease of fT3 and fT4 concentrations by the end of the third month of radioiodine therapy. Decreases in serum levels of sFas and sFasL and increases of Bcl-2 are regarded as characteristic for GD patients before radioiodine therapy. Radioiodine therapy reverses the ratio of estimated markers after four months. The concentrations of hormones reflect actual thyroid function, whereas concentrations of markers of apoptosis may suggest morphological changes. (author)

Patil, Veena A; Desai, Manthan H

The aim of the present study was to evaluate the effect of periodontal therapy on serum C-reactive protein (CRP) levels in patients with gingivitis and chronic periodontitis. A total of 60 subjects (30 males and 30 females) were included in the study with 20 subjects in each of the groups classified based on community periodontal index (CPI) scores: I: Healthy, II: Gingivitis, III: Mild periodontitis. Periodontal therapy was performed on groups II and III patients. Venous blood was collected from each subject at baseline and 3 months after periodontal therapy. The collected sample was subjected to biochemical analysis to detect CRP levels by using immunoturbidimetric method. The present study demonstrated that the periodontitis group had a higher mean CRP levels (2.49 ± 0.47 ng/ml) as compared to the gingivitis group (1.40 ± 0.32 ng/ml) and healthy group (0.56 ± 0.20 ng/ml). The mean CRP values after periodontal therapy were found to be reduced to 0.44 ± 0.23 ng/ml in group II and 1.30 ± 0.36 ng/ml in group III patients. Within the limitations of this study, it can be concluded that CRP level progressively increases from periodontal health to disease. A decrease in CRP levels with periodontal treatment was also observed. Due to its opsonizing abilities CRP plays an important role in the innate host defence. It can be hypothesized that CRP is a potential biomarker of periodontal disease. A number of studies have reported elevated serum CRP levels in periodontitis subjects. Long standing periodontal disease and raised CRP levels enhance the risk of cardiovascular disease, cerebrovascular accidents and preterm low birth weight infants. There is also evidence that effective periodontal therapy can lower serum CRP levels. However, the data of interventional studies on CRP in gingivitis and periodontitis is scarce.

Objective: To investigate the clinical significance of changes of serum IGF-II, CA19-9 and AFP levels after intervention therapy in patients with primary hepatic cancer. Methods: Serum levels of IGF-II, CA19-9 and AFP (with RIA) were repeatedly determined in 35 patients with primary hepatic cancer before intervention therapy, 1 month after intervention therapy and 6 months after intervention therapy as well as in 30 controls. Results: Before intervention therapy, serum levels of IGF-II, CA19-9 and AFP in the patients were significantly higher than those in the controls (P <0.01 ). One month after intervention therapy, all the serum levels were approaching normal. Six months later, the levels in the patients without recurrence remained normal. However, the levels in the 6 patients with recurrence returued to those before intervention therapy again. Conclusion: Changes of serum IGF-II, CA19-9 and AFP levels are closely related to the tumor burden and may reflect the presence of recurrence. (authors)

The potential mechanisms underlying the increase in serum iron concentration in gamma-irradiated mice were studied. The gamma irradiation dose used was 4 Gy, and cobalt-60 ( 60 Co) source was used for the irradiation. The dose rate was 0.25 Gy/min. In the serum of irradiated mice, the concentration of ferrous ions decreased, whereas the serum iron concentration increased. The concentration of ferrous ions in irradiated mice returned to normal at 21 day post-exposure. The concentration of reactive oxygen species in irradiated mice increased immediately following irradiation but returned to normal at 7 day post-exposure. Serum iron concentration in gamma-irradiated mice that were pretreated with reduced glutathione was significant lower (p < 0.01) than that in mice exposed to gamma radiation only. However, the serum iron concentration was still higher than that in normal mice (p < 0.01). This change was biphasic, characterized by a maximal decrease phase occurring immediately after gamma irradiation (relative to the irradiated mice) and a recovery plateau observed during the 7th and 21st day post-irradiation, but serum iron recovery was still less than that in the gamma-irradiated mice (4 Gy). In gamma-irradiated mice, ceruloplasmin activity increased and serum copper concentration decreased immediately after irradiation, and both of them were constant during the 7th and 21st day post-irradiation. It was concluded that ferrous ions in irradiated mice were oxidized to ferric ions by ionizing radiation. Free radicals induced by gamma radiation and ceruloplasmin mutually participated in this oxidation process. The ferroxidase effect of ceruloplasmin was achieved by transfer of electrons from ferrous ions to cupric ions. (orig.)

In photodynamic therapy (PDT), red light is administered 24 - 72 hours post intravenous (i.v.) injection of hematoporphyrin derivatives (HpD). In an earlier animal model study, more effective therapeutic response was obtained when red light irradiation was carried out 15 mins after the injection of HpD. The effectiveness of this immediate PDT protocol has been correlated to the high serum level of HpD immediately after administration and the destruction of the microcirculation system as the dominant tumor destruction mechanism. This study examines the pharmacokinetics and the serum levels of HpD in rats and also in human patients. Such data can assist in defining the optimum time delay for light irradiation in the PDT of cancer.

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

Potential use of serum HBV RNA in antiviral therapy for chronic hepatitis B in the era of nucleos(t)ide analogs.

2017-12-01

Although the efficacy of nucleos(t)ide analogue (NA) has been confirmed for treatment of chronic hepatitis B, long-term therapy has been recommended due to the high frequency of off-therapy viral DNA rebound and disease relapse. In this review, the RNA virion-like particles of hepatitis B virus (HBV) are integrated into the life cycle of HBV replication, and the potential significance of serum HBV RNA is systematically described. The production of HBV RNA virion-like particles should not be blocked by NA; in this regard, serum HBV RNA is found to be a suitable surrogate marker for the activity of intrahepatic covalently closed circular DNA (cccDNA), particularly among patients receiving NA therapy. Therefore, the concept of virological response is redefined as persistent loss of serum HBV DNA and HBV RNA. In contrast to hepatitis B surface antigen (HBsAg) that can originate from either the cccDNA or the integrated HBV DNA fragment, serum HBV RNA, with pregenomic RNA origination, can only be transcribed from cccDNA. Therefore, the loss of serum HBV RNA would likely be a promising predicator for safe drug discontinuation. The clinical status of consistent loss of serum HBV RNA accompanied with low serum HBsAg levels might be implicated as a "para-functional cure," a status nearly close to the functional cure of chronic hepatitis B, to distinguish the "functional cure" characterized as serum HBsAg loss with or without anti-HBs seroconversion.

Full Text Available Abstract Background Beta thalassemia is the most frequent genetic disorder of haemoglobin synthesis in Pakistan. Recurrent transfusions lead to iron-overload manifested by increased serum Ferritin levels, for which chelation therapy is required. Findings The study was conducted in the Pediatric Emergency unit of Civil Hospital Karachi after ethical approval by the Institutional Review Board of Dow University of Health Sciences. Seventy nine cases of beta thalassemia major were included after a written consent. The care takers were interviewed for the socio-demographic variables and the use of Desferrioxamine therapy, after which a blood sample was drawn to assess the serum Ferritin level. SPSS 15.0 was employed for data entry and analysis. Of the seventy-nine patients included in the study, 46 (58.2% were males while 33 (41.8% were females. The mean age was 10.8 (± 4.5 years with the dominant age group (46.2% being 10 to 14 years. In 62 (78.8% cases, the care taker education was below the tenth grade. The mean serum Ferritin level in our study were 4236.5 ng/ml and showed a directly proportional relationship with age. Desferrioxamine was used by patients in 46 (58.2% cases with monthly house hold income significant factor to the use of therapy. Conclusions The mean serum Ferritin levels are approximately ten times higher than the normal recommended levels for normal individuals, with two-fifths of the patients not receiving iron chelation therapy at all. Use of iron chelation therapy and titrating the dose according to the need can significantly lower the iron load reducing the risk of iron-overload related complications leading to a better quality of life and improving survival in Pakistani beta thalassemia major patients.

Autologous stem cell transplantation (ASCT) is the gold standard therapy for suitable multiple myeloma (MM) patients after induction with high dose therapy. To date, the evidence of a reliable marker of prognosis in these cases remains scarce. Our aim was to evaluate appearance of unrelated atypical serum immunofixation patterns (ASIPs) as a marker of prognosis in MM patients submitted to ASCT. We retrospectively analysed data from 65 patients. Interestingly, we observed that presence of ASIPs was associated with longer progression-free survival and longer overall survival. Our results suggested that presence of ASIPs could be a novel marker of good prognosis in MM patients submitted to ASCT.

Normal lactating mothers were administered a single dose of 60 or 210 mg beta-carotene and changes in serum and milk retinol, alpha-tocopherol, and carotenoids were monitored for 8 d. Average serum beta-carotene concentrations increased 4.1- and 4.0-fold after the 60- and 210-mg doses, respectively. Milk beta-carotene concentrations increased 4.1- and 3.0-fold after the 60- and 210-mg doses, respectively. Maximum serum concentrations were reached 24 h after both supplements, although concentrations of milk beta-carotene continued to rise for 2-3 d. After 8 d, both serum and milk beta-carotene continued to rise for 2-3 d. After 8 d, both serum and milk beta-carotene concentrations remained about twofold higher than baseline concentrations. Increases in serum or milk beta-carotene concentrations were not dose-dependent. Initial serum and milk concentrations of beta-carotene predicted increases after supplementation, and increases in serum beta-carotene concentrations predicted those in milk. Concentrations of milk carotenoids were less than one-tenth their respective concentrations in serum. Lutein, beta-cryptoxanthin, lycopene, alpha-carotene, retinol, and alpha-tocopherol concentrations in serum or milk did not change significantly after beta-carotene supplementation. Retinol esters account for most of the retinol equivalents in the milk of well-nourished mothers. Initial and maximum concentrations of beta-carotene in serum and milk were strongly correlated for individual mothers. Collectively, the data showed that a single 60-mg supplement of beta-carotene sustained elevated beta-carotene concentrations in serum and milk for > 1 wk in normal mothers but did not affect concentrations of other major carotenoids, retinol, or alpha-tocopherol.

Optimum use of fluoride therapy for osteoporosis requires a sensitive and convenient index of the skeletal response to fluoride. Since previous studies had shown that serum alkaline phosphatase activity (SALP) was increased in response to fluoride therapy, we examined serial measurements of SALP in 53 osteoporotics treated with 66 to 110 mg of sodium fluoride (NaF) for 12 to 91 months. SALP was increased in 87% of the subjects during therapy with fluoride. The increase in SALP was thought to reflect the osteogenic action of fluoride based on the findings that SALP correlated with both trabecular bone area (r = .81, P less than .001) and osteoid length (r = .67, P less than .01) in iliac crest biopsies, predicted increased bone density on spinal radiographs in response to fluoride therapy with an 87% accuracy, and predicted decreased back pain in response to fluoride with a 91% accuracy. In addition, the SALP response to fluoride was seen earlier than other therapeutic responses as indicated by the findings that the tau 1/2 for the SALP response (ie, time for 1/2 of the patients to show a significant response) was significantly less (1.2 +/- 0.3 yr) than that for the pain response (1.6 +/- 0.3 yr, P less than .05) or that for the radiographic response (3.7 +/- 0.5 yr, P less than .001). Although most patients responded to fluoride with an increase in SALP, evaluation of the kinetics of the SALP response to fluoride revealed marked interpatient variation.(ABSTRACT TRUNCATED AT 250 WORDS)

Levothyroxine replacement treatment in hypothyroidism is unable to restore physiological thyroxine and triiodothyronine concentrations in serum and tissues completely. Normal serum thyroid stimulating hormone (TSH) concentrations reflect only pituitary euthyroidism and, therefore, novel biomarkers representing tissue-specific thyroid state are needed. MicroRNAs (miRNAs), small non-coding regulatory RNAs, exhibit tissue-specific expression patterns and can be detectable in serum. Previous studies have demonstrated differential expression of (precursors of) miRNAs in tissues under the influence of thyroid hormone. To study if serum miRNA profiles are changed in different thyroid states. We studied 13 athyroid patients (6 males) during TSH suppressive therapy and after 4 weeks of thyroid hormone withdrawal. A magnetic bead capture system was used to isolate 384 defined miRNAs from serum. Subsequently, the TaqMan Array Card 3.0 platform was used for profiling after individual target amplification. Mean age of the subjects was 44.0 years (range 20-61 years). Median TSH levels were 88.9 mU/l during levothyroxine withdrawal and 0.006 mU/l during LT4 treatment with a median dosage of 2.1 μg/kg. After normalization to allow inter-sample analysis, a paired analysis did not demonstrate a significant difference in expression of any of the 384 miRNAs analyzed on and off LT4 treatment. Although we previously showed an up-regulation of pri-miRNAs 133b and 206 in hypothyroid state in skeletal muscle, the present study does not supply evidence that thyroid state also affects serum miRNAs in humans.

To investigate the pathopysiologic mechanisms of nickel-induced erythocytosis, serum erythropoietin activities were measured in (a) pooled serum from rats at 2 wk after intrarenal injection of αNi 3 S 2 (5 mg/rat), and (b) pooled serum from control rats at 2 wk after intrarenal injection of sterile NaCl vehicle (0.4 ml/rat). A sensitive erythropoietin bioassay was employed, which entailed repetitive administration of test serums to post-hypoxic polycythemic mice in divided doses (12 s.c. injections of 0.5 ml of serum at 6 h intervals for 3 da; total dose = 6 ml of serum/mouse). The erythropoietin detection limit was approx. = 20 I.U./liter of serum. In mice which received pooled serum from αNi 3 S 2 -treated rats, erythrocyte 59 Fe-uptake averaged 28% (S.D. +- 5) (vs 3.7 +- 1.1% in control rats; P 3 S 2 -treated rats averaged 130 I.U./liter (S.D. +- 18) (vs 27 +- 6 I.U./liter in control rats; P 3 S 2 is mediated by increased serum erythropoietin activity

To observe the effect of bleeding and cupping therapy on postherpetic neuralgia (PHN) and preliminarily discuss the analgesic mechanism. Sixty-four cases of PHN were randomized into two groups, 32 cases in each one. In the bleeding and cupping group, the local pricking with syringe needle and cupping was applied in the local painful area, once every two days. And totally 8 treatments were required. In the pregabalin group, pregabalin was prescribed for oral administration, 150mg/time, twice a day. And totally 16 days of medication were required. Visual analogue scale (VAS) score and the changes of P substance content in the peripheral and local serum before and after treatment were observed in the two groups. VAS score and peripheral serum P substance after treatment were lower significantly than those before treatment in the two groups (all Pcupping group was much more significant (Pcupping group [(93.86 +/- 9.87) pg/mL vs (46.13 +/- 6.31) pg/mL, Pcupping therapy achieves the definite efficacy on PHN and it can reduce significantly peripheral and local serum P substance content in the patients. It is possibly one of the mechanisms of analgesic effect.

Large burn injuries induce a systemic response in affected patients. Soluble ST2 (sST2) acts as a decoy receptor for interleukin-33 (IL-33) and has immunosuppressive effects. sST2 has been described previously as a prognostic serum marker. Our aim was to evaluate serum concentrations of sST2 and IL-33 after thermal injury and elucidate whether sST2 is associated with mortality in these patients. We included 32 burn patients (total body surface area [TBSA] >10%) admitted to our burn intensive care unit and compared them to eight healthy probands. Serum concentrations of sST2 and IL-33 were measured serially using an enzyme-linked immunosorbent assay (ELISA) technique. The mean TBSA was 32.5%±19.6%. Six patients (18.8%) died during the hospital stay. Serum analyses showed significantly increased concentrations of sST2 and reduced concentrations of IL-33 in burn patients compared to healthy controls. In our study cohort, higher serum concentrations of sST2 were a strong independent predictor of mortality. Burn injuries cause an increment of sST2 serum concentrations with a concomitant reduction of IL-33. Higher concentrations of sST2 are associated with increased in-hospital mortality in burn patients.

Patients with active pulmonary sarcoidosis underwent bronchoalveolar lavage, gallium scan, and serum angiotensin-converting enzyme (ACE) level determination prior to treatment with corticosteroids. Pulmonary function was tested before and after therapy. Increase in vital capacity after treatment ranged from 40 to 1,030 ml; 12 of the 16 patients studied had an increase of more than 200 ml. There was a close correlation between the percentage uptake of gallium scan and the increase of the vital capacity after therapy (r . 0.95, p less than 0.01). There was no relationship between the percentage of lymphocytes obtained on lavage and the changes in vital capacity with therapy (r . 0.05). There was a positive correlation between the changes in vital capacity and the ratio of T4(+):T8(+)lymphocytes (r . 0.62, p less than 0.05) and number of T4 (+) lymphocytes (r . 0.92, p less than 0.01) in the bronchoalveolar fluid. There was a low correlation between the pretreatment ACE level and the change in vital capacity (r . 0.368, p greater than 0.05)

The use of low level laser for body contouring and weight reduction depends on the photochemical non thermal effect of laser light on the adipose tissue. LLLT was reported to liquefy or release stored fat in adipocytes by the opening of specialized yet not identified cell membrane-associated pores after a brief treatment The concentration of leptin in adipose tissue and serum closely parallel the mass of adipose tissue and adipocyte size and triglycerides content. Thus, leptin increases in obesity and falls with weight loss. The current study was conducted to evaluate the effect of the low level laser therapy (LLLT) on leptin hormone, Cholesterol and triglyceride in both overweight and obese females. Twenty women were included in this study. Their ages ranged from 30-40 years. They were divided into two equal groups. Group A (Overweight group): included 10 females with BMI between 25 and 29.9 Kg/m2 -Group B (Obese group): included 10 females with BMI . 30. Both groups received LLL to the abdomen using laser scanner for uniform distribution of the beam above and below the umbilicus. Duration of treatment was 30 minutes, 2 times per week for 8 weeks as a total period of treatment. Serum level of leptin was estimated by radioimmunoassay (RIA). As regards serum cholesterol and triglyceride they were determined by enzymatic colorimetric test. Biochemical assessments were done before and after treatment. Results of the present study showed that in the overweight group laser treatment resulted in highly significant reduction in leptin serum level accompanied by highly significant increase in serum triglycerides level. Meanwhile, the increase in cholesterol level was insignificant. As regards the obese group, alteration in serum leptin level caused by laser treatment was not significant. In this group the increase in triglycerides and cholesterol serum levels after treatment were highly significant

Acute binge drinking increases serum endotoxin and bacterial DNA levels in healthy individuals.

Full Text Available Binge drinking, the most common form of alcohol consumption, is associated with increased mortality and morbidity; yet, its biological consequences are poorly defined. Previous studies demonstrated that chronic alcohol use results in increased gut permeability and increased serum endotoxin levels that contribute to many of the biological effects of chronic alcohol, including alcoholic liver disease. In this study, we evaluated the effects of acute binge drinking in healthy adults on serum endotoxin levels. We found that acute alcohol binge resulted in a rapid increase in serum endotoxin and 16S rDNA, a marker of bacterial translocation from the gut. Compared to men, women had higher blood alcohol and circulating endotoxin levels. In addition, alcohol binge caused a prolonged increase in acute phase protein levels in the systemic circulation. The biological significance of the in vivo endotoxin elevation was underscored by increased levels of inflammatory cytokines, TNFα and IL-6, and chemokine, MCP-1, measured in total blood after in vitro lipopolysaccharide stimulation. Our findings indicate that even a single alcohol binge results in increased serum endotoxin levels likely due to translocation of gut bacterial products and disturbs innate immune responses that can contribute to the deleterious effects of binge drinking.

The relationship between periodontal disease and systemic disease is revealing new and exciting associations. Idiopathic edema presents a clinical syndrome with obscure pathophysiology. The present study investigates whether non-surgical periodontal therapy is beneficial in patients who are not responding to conventional treatment of idiopathic edema. Thirty patients with idiopathic edema were allocated to intervention and control groups. All the subjects were assessed for systemic (body weight, body mass index, visual scale of edema, serum C-reactive protein, and serum albumin) and periodontal (plaque index, calculus index, and gingival index) parameters. Non-surgical periodontal therapy, including oral hygiene instructions, scaling and root planing, and systemic antibiotic therapy, was provided in the intervention group. Both groups were reevaluated after 4 weeks. Both groups were comparable at baseline. All parameters, except serum albumin, showed significant improvement after periodontal therapy. The control group showed further worsening of these parameters. This study shows that sources for systemic inflammation, such as periodontal disease, could affect the pathogenesis of idiopathic edema. Successful elimination of such covert sources of inflammation leads to a clinical benefit in patients who are distressed by this condition.

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

Pentobarbital serum concentrations associated with a high-dose therapeutic regimen were determined using EMIT immunoassay reagents. Replicate analyses of serum controls resulted in a within-assay coefficient of variation of 5.0% and a between-assay coefficient of variation of 10%. Regression analysis of 44 serum samples analyzed by this technique (y) and a reference procedure (x) were y = 0.98x + 3.6 (r = 0.98; x = ultraviolet spectroscopy) and y = 1.04x + 2.4 (r = 0.96; x = high-performance liquid chromatography). Clinical evaluation of the results indicates the immunoassay is sufficiently sensitive and selective for pentobarbital to allow accurate quantitation within the therapeutic range associated with high-dose therapy.

Full Text Available Objective: Brain-derived neurotrophic factor (BDNF levels are decreased in individuals with depression and increase following antidepressant treatment. The objective of this study is to compare pre- and post-treatment serum BDNF levels in patients with drug-resistant major depressive disorder (MDD who received either electroconvulsive therapy (ECT or repetitive transcranial magnetic stimulation (rTMS. It is hypothesized that non-pharmacological treatments also increase serum BDNF levels.Methods: This was a prospective, single-blind study comparing pre- and post-treatment serum BDNF levels of twenty-nine patients with drug-resistant MDD who received ECT or rTMS treatment. Serum BDNF levels were measured one week prior to and one week after treatment using the sandwich ELISA technique. Depression severity was measured one week before and one week after treatment using the Hamilton Depression Rating Scale. Two-sided normal distribution paired t-test analysis was used to compare pre- and post-treatment BDNF concentration and illness severity. Bivariate correlations using Pearson's coefficient assessed the relationship between post-treatment BDNF levels and post-treatment depression severity.Results: There was no significant difference in serum BDNF levels before and after ECT, although concentrations tended to increase from a baseline mean of 9.95 ng/ml to 12.29 ng/ml after treatment (p= 0.137. Treatment with rTMS did not significantly alter BDNF concentrations (p= 0.282. Depression severity significantly decreased following both ECT (p= 0.003 and rTMS (p< 0.001. Post-treatment BDNF concentration was not significantly correlated with post-treatment depression severity in patients who received either ECT (r= -0.133, p= 0.697 or rTMS (r= 0.374, p= 0.126.Conclusion: This study suggests that ECT and rTMS may not exert their clinical effects by altering serum BDNF levels. Serum BDNF concentration may not be a biomarker of ECT or rTMS treatment response.

Fourteen hyperthyroid patients (11 men, three women), ages 28 to 66, were followed with serial measurements of serum thyroid hormone levels for 1 mo after therapy with I-131. Twelve patients had diffuse toxic goiters (25 to 70 g in size); two patients had multinodular glands (40 to 100 g). The patients were taking no antithyroid medications; ten patients were treated with propranolol. All patients received the equivalent of 5000 rad, except the two with multinodular glands, who received larger doses. There was no consistent pattern of serum T 4 and T 3 levels after the I-131 therapy. For the entire group, there was no significant increase of the mean serum hormone concentration. One group (three patients) had a mean T 4 increase of 28% and a T 3 increase of 91% above baseline at Days 10--11. Seven patients had minimal increases of hormone levels at Days 2--3, and a third group (four paients) had no increase of thyroid hormones after I-131 therapy. The patients with no rise in hormone concentrations had smaller goiters than the other groups. There was no correlation of the dose of radioactive iodine, or of the initial hormone concentration, with the rises or declines of T 4 and T 3 levels after I-131 therapy. Radioiodine therapy caused no significant increase of serum T 4 and T 3 concentrations in the majority of patients

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

Full Text Available BackgroundProgression of liver fibrosis is characterized by synthesis and degradation of extracellular matrix (ECM. Matrix-metalloproteinases (MMP cleave collagen fibers at a specific site and thereby generate soluble fragments of ECM (neo-epitopes. The levels of these neo-epitopes might reflect the stage of liver fibrosis and may allow monitoring of anti-fibrotic therapies. Here we analyzed these neo-epitopes as read-out for a liver directed therapy with statins.MethodsBile duct ligation (BDL was performed on wildtype rats, which received atorvastatin (15mg/kg*d for one week starting at one, two, three, four and five weeks after BDL (T1-T5, while controls remained untreated. Hepatic fibrosis was analyzed by immunohistochemistry and hepatic hydroxyproline content. TGFβ levels were measured by RT-PCR. Proteolytic activity of MMP-2 was examined by zymography. Levels of degradation MMP driven type I, III, IV and VI collagen degradation (C1M, C3M, C4M and C6M and type III and IV collagen formation (PRO-C3 and P4NP7S markers were assessed by specific ELISAs in serum probes.ResultsSerum markers of ECM neo-epitopes reflected significantly the deposition of ECM in the liver and were able to distinguish between early (T1-T3 and severe fibrosis (T4-T5. Statin treatment to the fibrotic livers resulted in reduction of neo-epitope markers, especially when therapy was started in the stage of severe fibrosis (T4-T5. Furthermore, these markers correlated with hepatic expression of profibrotic cytokines TGFβ1 and TGFβ2. Formation markers of type III and IV collagen (PRO-C3 and P4NP7S and degradation markers C4M and C6M correlated significantly with MMP-2 activity in rats with severe fibrosis. ConclusionDetermination of ECM remodelling turnover markers in serum allowed a distinction between mild and severe fibrosis. With respect to statin therapy, the markers may serve as read-out for efficacy of anti-fibrotic treatment.

Full Text Available Objective: To analyze the efficacy of calcium supplementation plus vitamin D on the improved concentrations of serum 25(OHD and the blood pressure in working women of childbearing age. Methods: The design used in this research was an experimental study (randomized control trial, with 39 subjects of women at childbearing age who met the inclusion criteria for the study. Subjects were randomly allocated into two treatment groups, the VDC group (400 IU of vitamin D plus 500 mg of calcium and the VD group (400 IU of vitamin D. Supplements were consumed every day for 12 weeks. Results: Prior to supplementation, the average level of serum 25(OHD in the VDC group was (16.7 ± 4.5 ng/dL which was higher than the average level of serum 25(OHD in the VD group which was (14.9 ± 5.1 ng/dL. After supplementation, the subjects of VDC group showed an average increased 3.6 ng/dL of serum 25(OHD. The average increase of serum 25(OHD in VD group was 6.3 ng/dL. The increase of serum 25(OHD in VDC group was 21.6%, while in the VD group the increase was almost two times higher (42.3% than that of the VDC group. Statistical test results showed that the average levels of serum 25(OHD between the two treatment groups were significantly different. Conclusions: The average systolic blood pressure prior to supplementation of the VDC group was (128.5 ± 22.5 mmHg which was slightly lower than that of the VD group [(131.1 ± 18.0 mmHg].

To describe the clinical and laboratory findings of a dog with gastric perforation, resulting in a markedly increased peritoneal effusion-to-serum potassium ratio. A 6-year-old mixed breed neutered male dog presented with a right femoral fracture after being hit by car. The fracture was repaired surgically. Four days postoperatively, the dog developed peritoneal effusion, confirmed with ultrasonography. Peritoneal effusion analysis and serum biochemistry, performed concurrently, showed blood-to-effusion glucose difference >1.1 mmol/L [>20 mg/dL], suggesting the effusion was septic. The effusion-to-serum creatinine ratio was mildly increased (1.36) and the effusion-to-serum potassium ratio was markedly increased (>2.67). Combined, these findings were suggestive of a septic uroabdomen. A positive contrast retrograde urethrocystography did not reveal urine leakage from the lower urinary tract. An exploratory laparotomy revealed a gastric perforation in the pyloric area and an intact urinary tract. Gastric perforation should be considered a differential diagnosis in dogs with an increased peritoneal effusion to serum potassium ratio. © Veterinary Emergency and Critical Care Society 2016.

Background: Plasma or serum zinc concentration (PZC or SZC) is the primary measure of zinc status, but accurate sampling requires controlling for hemolysis to prevent leakage of zinc from erythrocytes. It is not established how much hemolysis can occur without changing PZC/SZC concentrations. Objective: This study determines a guideline for the level of hemolysis that can significantly elevate PZC/SZC. Methods: The effect of hemolysis on PZC/SZC was estimated by using standard hematologic variables and mineral content. The calculated hemolysis threshold was then compared with results from an in vitro study and a population survey. Hemolysis was assessed by hemoglobin and iron concentrations, direct spectrophotometry, and visual assessment of the plasma or serum. Zinc and iron concentrations were determined by inductively coupled plasma spectrometry. Results: A 5% increase in PZC/SZC was calculated to result from the lysis of 1.15% of the erythrocytes in whole blood, corresponding to ∼1 g hemoglobin/L added into the plasma or serum. Similarly, the addition of simulated hemolysate to control plasma in vitro caused a 5% increase in PZC when hemoglobin concentrations reached 1.18 ± 0.10 g/L. In addition, serum samples from a population nutritional survey were scored for hemolysis and analyzed for changes in SZC; samples with hemolysis in the range of 1-2.5 g hemoglobin/L showed an estimated increase in SZC of 6% compared with nonhemolyzed samples. Each approach indicated that a 5% increase in PZC/SZC occurs at ∼1 g hemoglobin/L in plasma or serum. This concentration of hemoglobin can be readily identified directly by chemical hemoglobin assays or indirectly by direct spectrophotometry or matching to a color scale. Conclusions: A threshold of 1 g hemoglobin/L is recommended for PZC/SZC measurements to avoid increases in zinc caused by hemolysis. The use of this threshold may improve zinc assessment for monitoring zinc status and nutritional interventions.

Research on the correlation of serum bilirubin level with cardiac function as well as outcomes in heart failure patients with cardiac resynchronization therapy (CRT) has not yet been reported. The aim of this study was to analyze the relationship between change in serum bilirubin level and left ventricular reverse remodeling, and also to clarify the impact of bilirubin change on clinical outcomes in CRT patients. We evaluated 105 consecutive patients who underwent CRT. Patients who had no serum total-bilirubin data at both baseline and 3-9 months' follow-up or had died less than 3 months after CRT implantation were excluded. Accordingly, a total of 69 patients were included in the present analysis. The patients were divided into two groups: decreased bilirubin group (serum total-bilirubin level at follow-up≤that at baseline; n=48) and increased bilirubin group (serum total-bilirubin level at follow-up>that at baseline; n=21). Mean follow-up period was 39.3 months. In the decreased bilirubin group, mean left ventricular end-systolic diameter decreased from 54.5mm to 50.2mm (p=0.001) and mean left ventricular ejection fraction increased significantly from 29.8% to 37.0% (p=0.001). In the increased bilirubin group, there was no significant change in echocardiographic parameters from baseline to follow-up. In Kaplan-Meyer analysis, cardiac mortality combined with heart failure hospitalization in the increased bilirubin group was significantly higher than that in the decreased bilirubin group (log-rank p=0.018). Multivariate Cox regression analysis revealed that increased bilirubin was an independent predictor of cardiac mortality combined with heart failure hospitalization (OR=2.66, p=0.023). The change in serum bilirubin is useful for assessment of left ventricular reverse remodeling and prediction of outcomes in heart failure patients with CRT.

A limited number of studies have been conducted on the effects of hormonal therapy with tamoxifen (TMX) or aromatase inhibitors (AIs) on plasma levels of leptin and adiponectin, as well as body composition in breast cancer (BC) patients. Therefore, we aimed to analyze the relationship between adipocytokines and body composition as well as the effects of TMX and AIs on plasma adiponectin, leptin, leptin/adiponectin ratio (LAR) and body composition. Patients were treated with either TMX or AI according to their menopausal status after adjuvant radiotherapy. Changes in body composition and serum leptin and adiponectin levels were evaluated. We recorded the type of hormonal therapy, BMI, waist/hip ratio (WHR), leptin and adiponectin levels at study entry, and after 6 and 12 months. From baseline to the 6- and 12-month follow-ups, there were statistically significant increases in WHR (p = 0.003), fat mass (p = 0.041), and serum leptin (p body composition and serum leptin and adiponectin levels were similar in TMX and AI groups. A statistically significant decrease was found in total body water and LAR (p body fat percentage increased, such increases were not statistically significant. A positive correlation was found between baseline BMI and serum leptin levels. This correlation was maintained at 6 and 12 months. The negative correlation found between serum adiponectin levels at baseline and baseline BMI did not last throughout the study. In this study, increased leptin and adiponectin levels and a decreased LAR were found in both AI and TMX groups. These changes might have occurred through both mechanisms of hormonal therapy and body composition changes. Therefore, AIs and TMX may exert their protective effects for BC patients by decreasing LAR rather than affecting leptin or adiponectin alone. © 2015 S. Karger AG, Basel.

The effects of radiation on the thyroid were investigated in 102 patients treated by radiation therapy to the neck. All patients had radiation ports which included the thyroid gland. Serum thyroid stimulating hormone (TSH) levels were elevated in 41 cases and the cumulative elevation rate was 52.1% in 5 years. The high frequency of elevated serum TSH levels observed in patients whose thyroid glands were included within the radiation fields (74.1%) was statistically significant compared to those whose thyroid glands were only partially included (23.4%). Among the patients whose entire thyroid glands were included within the radiation field, combination with chemotherapy increased the frequency of elevated serum TSH levels, but the increase was not statistically significant. Among 36 laryngeal cancer patients treated by only radiation therapy through a portal encompassing part of the thyroid, 4 (14%) were found to have elevated serum TSH levels. We advocate routine monitoring of thyroid functions after radiation therapy to the neck. (author)

Short bowel syndrome is a severe malabsorption disorder, and prolonged parenteral nutrition is essential for survival in some cases. Among the undesirable effects of long-term parenteral nutrition is an increase in proinflammatory cytokines. The aim of the present study was to measure the serum levels of interleukin-6, interleukin-10, tumor necrosis factor alpha, and transforming growth factor beta, in patients with short bowel syndrome on cyclic parenteral nutrition and patients who had previously received but no longer require parenteral nutrition. The study was cross-sectional and observational. Three groups were studied as follows: Parenteral nutrition group, 9 patients with short bowel syndrome that receive cyclic parenteral nutrition; Oral nutrition group, 10 patients with the same syndrome who had been weaned off parenteral nutrition for at least 1 year prior to the study; Control group, 13 healthy adults, matched for age and sex to parenteral and oral groups. The following data were collected: age, tobacco use, drug therapies, dietary intake, body weight, height, blood collection. All interleukins were significantly higher in the parenteral group compared with the control group as follows: interleukin-6: 22 ± 19 vs 1.5 ± 1.4 pg/mL, P= .0002; transforming growth factor β: 854 ± 204 vs 607 ± 280 pg/mL, P= .04; interleukin-10: 8 ± 37 vs 0.6 ± 4, P= .03; tumor necrosis factor α: 20 ± 8 vs 8 ± 4 pg/mL, Pparenteral nutrition in short bowel syndrome patients, regardless of its duration, increases serum proinflammatory cytokines.

Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre......-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP......-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median...

Assessment of the effect of non-surgical periodontal therapy (SRP) on serum inflammatory parameters in patients with untreated aggressive (AgP) and chronic (ChP) periodontitis. Overall, 31 ChP and 29 AgP were examined clinically prior to and 12 weeks after SRP (subgingival scaling of all pockets within 2 days) with systemic antibiotics for patients positive for Aggregatibacter actinomycetemcomitans (14 AgP, 9 ChP). Blood was sampled prior to, one day, 6, and 12 weeks after the first SRP visit. Serum elastase, C-reactive protein (CRP), lipopolysaccharide-binding protein (LBP), interleukin (IL) 6, 8, and leukocyte counts were assessed. At baseline, serum elastase, CRP, and LBP were significantly (p < 0.01) higher in AgP than ChP. Serum elastase, CRP, LBP, and IL-6 were significantly (p < 0.001) elevated one day after scaling in both groups. Both groups showed significant clinical improvement (p < 0.001). A significant difference was observed regarding change of serum elastase 12 weeks after SRP between AgP and ChP (p = 0.015). Multiple regression analysis revealed AgP, African origin, and bleeding on probing to be associated with more pronounced elastase reduction. CRP reduction was associated with African origin, systemic antibiotics, and baseline probing pocket depth. SRP results in serum elastase reduction in AgP but not in ChP. © 2013 John Wiley & Sons A/S.

Serum phosphate predicts early mortality in adults starting antiretroviral therapy in Lusaka, Zambia: a prospective cohort study.

Full Text Available BACKGROUND: Patients starting antiretroviral therapy (ART for acquired immunodeficiency syndrome (AIDS in sub-Saharan Africa have high rates of mortality in the initial weeks of treatment. We assessed the association of serum phosphate with early mortality among HIV-infected adults with severe malnutrition and/or advanced immunosuppression. METHODOLOGY/PRINCIPAL FINDINGS: An observational cohort of 142 HIV-infected adults initiating ART in Lusaka, Zambia with body mass index (BMI <16 kg/m(2 or CD4(+ lymphocyte count <50 cells/microL, or both, was followed prospectively during the first 12 weeks of ART. Detailed health and dietary intake history, review of systems, physical examination, serum metabolic panel including phosphate, and serum ferritin and high-sensitivity C-reactive protein (hsCRP were monitored. The primary outcome was mortality. Baseline serum phosphate was a significant predictor of mortality; participants alive at 12 weeks had a median value of 1.30 mmol/L (interquartile range [IQR]: 1.04, 1.43, compared to 1.06 mmol/L (IQR: 0.89, 1.27 among those who died (p<0.01. Each 0.1 mmol/L increase in baseline phosphate was associated with an incremental decrease in mortality (AHR 0.83; 95% CI 0.72 to 0.95. The association was independent of other metabolic parameters and known risk factors for early ART-associated mortality in sub-Saharan Africa. While participant attrition represented a limitation, it was consistent with local program experience. CONCLUSIONS/SIGNIFICANCE: Low serum phosphate at ART initiation was an independent predictor of early mortality among HIV patients starting ART with severe malnutrition or advanced immunosuppression. This may represent a physiologic phenomenon similar to refeeding syndrome, and may lead to therapeutic interventions that could reduce mortality.

2018-05-01

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

Little is known about serum concentrations of Matrix Metalloproteinase-9 (MMP-9), MMP-2, TIMP-1 and TIMP-2 in diabetic patients with foot ulcers. This study demonstrates their relationship with wound healing. Ninety-four patients with diabetic foot ulcers were recruited in the study. Serum MMP-9, MMP-2, TIMP-1 and TIMP-2 were measured at the first clinic visit and the end of 4-week treatment and followed up till 12 weeks. According to the decreasing rate of ulcer healing area at the fourth week, we divided those cases into good and poor healers. Through analyses, we explore the possible relationship among those factors and degree of wound healing. The median level of serum MMP-9 in good healers was lower than poor healers at first visit (124.2 μg/L vs 374.6 μg/L, phealing than MMP-9 alone before therapy and after 4 week treatment (r = -0.6475 vs -0.3251, r = -0.7096 vs -0.1231, respectively). Receiver Operator Curve (ROC) showed that the cutoff for MMP-9/TIMP-1 ratio at healing and might provide a novel target for the future therapy in diabetic foot ulcers. Copyright © 2013 Elsevier Inc.

measured by immunoassay, and potential determinants of the serum sortilin level were assessed by generalized linear models. Serum levels of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) were measured in previous studies. We identified a significant increase of serum...... sortilin levels in depressed individuals compared with controls (P = 0.0002) and significant positive correlation between serum sortilin levels and the corresponding levels of BDNF and VEGF. None of the genotyped SNPs were associated with depression. Additional analyses showed that the serum sortilin level...... was influenced by several other factors. Alcohol intake and body mass index, as well as depression, serum BDNF and serum VEGF were identified as predictors of serum sortilin levels in our final multivariate model. In conclusion, the results suggest a role of circulating sortilin in depression which may relate...

Purpose: Our aim was to investigate the association of clinical factors, dosimetric parameters, and biomarkers with postoperative pulmonary complications (PPCs) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) treated by neoadjuvant concurrent chemoradiation therapy (CCRT) under strict pulmonary dose constraints and esophagectomy. Methods and Materials: We prospectively enrolled 112 patients undergoing trimodality treatment (including radiation therapy [40 Gy], concurrent taxane-/5-fluorouracil-based regimens, and radical esophagectomy) for ESCC. A PPC was defined as pneumonia or acute respiratory distress syndrome within 30 days after surgery. Serum samples were collected before and within 1 month after CCRT. The association of serum biomarkers with PPCs was detected by proximity ligation assay (PLA) and verified by enzyme-linked immunosorbent assay. Associations of clinical factors, lung dosimetric parameters, and biomarkers with PPC were tested statistically. Results: Thirty-three patients (29.5%) had PPCs. None of the dosimetric parameters was associated with PPCs. Preoperative functional vital capacity (FVC) was significantly associated with PPCs (P=.004). Of the 15 PLA-screened biomarkers, posttreatment transforming growth factor-β1 (TGF-β1) was borderline significantly associated with PPCs (P=.087). Patients with PPCs had significantly larger pre-CCRT to post-CCRT decrease in serum TGF-β1 concentration (−11,310 vs −5332 pg/mL, P=.005) and higher pre-CCRT to post-CCRT percent decline in serum TGF-β1 concentration (−37.4% vs −25.0%, P=.009) than patients without PPCs. On multivariate analysis, preoperative FVC (P=.003) and decrease in TGF-β1 >7040 pg/mL (P=.014) were independent factors associated with PPCs. Conclusions: Preoperative FVC and decrease in serum TGF-β1 level after dose-limited CCRT to the lung are associated with the development of PPCs.

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

International Nuclear Information System (INIS)

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

1987-01-01

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

Serum thyroglobulin (Tg) level is frequently elevated shortly after radioactive iodine (RAI) ablation therapy. The authors studied the relationship between the elevation of serum Tg after RAI therapy and iodine uptake pattern on post-ablation whole body scans (RxWBSs) in patients with papillary thyroid carcinoma (PTC). The study subjects were patients with PTC that had undergone first RAI therapy with thyroid hormone withdrawal after total thyroidectomy. Patients with a high level of serum anti-Tg antibody (TgAb, ≥ 60 U/mL), possible regional or distant metastasis as determined by pre-ablation or post-ablation studies, and negative iodine uptake of the anterior neck on RxWBS were excluded. Serum Tg was checked twice, that is, 7 days after (post-ablation Tg) and on the day of RAI therapy (pre-ablation Tg). Ratio of pre-ablation Tg to post-ablation Tg (Tg ratio) was used to assess changes in serum Tg levels after RAI therapy. Patients were classified into two groups according to the presence of midline uptake above the thyroidectomy bed on RxWBS (negative (group 1) or positive (group 2) midline uptake). Variables were subjected to analysis to identify differences between the two groups. Two hundred and fifty patients were enrolled in this study; 101 in group 1 and 149 in group 2. Based on univariate analysis, post-ablation Tg (8.12 ± 11.05 vs. 34.12 ± 54.31; P < 0.001) and Tg ratio (7.81 ± 8.98 vs. 20.01 ± 19.84; P < 0.001) were significantly higher in group 2. On the other hand, gender, tumor (T) stage, lymph node (N) stage, size, multiplicity or bilaterality of primary tumor, dose of 131I, serum TgAb and thyroid-stimulating hormone (TSH) level (before or after RAI therapy) were not significantly different in the two groups. Variables with P values of < 0.25 by univariate analysis were subjected to multivariate analysis, which showed post-ablation Tg (OR 1.060, 95 % CI = 1.028–1.092; P < 0.001) and Tg ratio (OR 1.059, 95 % CI�

The goal of this work was to determine if immediate versus postponed centrifugation of samples affects the levels of serum potassium. Twenty participants donated normal venous blood that was collected in four serum separator tubes per donor, each of which was analyzed at 0, 1, 2, or 4 hr on the Siemens Advia 1800 autoanalyzer. Coefficients of variation (CVs) for potassium levels ranged from 0% to 7.6% with a mean of 3 ± 2%. ANOVA testing of the means for all 20 samples showed a P-value of 0.72 (>0.05) indicating that there was no statistically significant difference between the means of the samples at the four time points. Sixteen samples were found to have CVs that were ≤5%. Two samples showed increases of potassium from the reference range to levels higher than the upper reference limit, one of which had a 4-hr value that was within the reference or normal range (3.5-5 mEq/l). Overall, most samples were found to have reproducible levels of serum potassium. Serum potassium levels from stored whole blood collected in serum separator tubes are, for the most part, stable at room temperature for at least 4 hr prior to analysis. However, some samples can exhibit significant fluctuations of values. © 2015 Wiley Periodicals, Inc.

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

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

Identification of blood biomarkers that can be useful for predicting Mycobacterium tuberculosis (M.TB) infection, effect of therapy and Multi Drug Resistant (MDR) TB infected individuals is clinically useful for combating tuberculosis epidemic. In this study, we have evaluated the levels of selected miRNAs in serum of TB and MDR TB patients. In addition, we have studied their levels in serum of patients post-therapy. The levels of 4-miRNAs (miR-16, miR-29a, miR-125b and miR-155) were measured in 30 newly diagnosed TB patients, 19 Multi Drug Resistant (MDR) TB patients, 10 patients who completed TB therapy and were TB negative. 30 healthy individuals were recruited as controls. The levels of the miRNAs were estimated by qRT-PCR. Of the four miRNAs studied, the levels of miR-16 were significantly elevated and miR-155 were significantly reduced in serum of TB patients as compared to uninfected controls. The Receiver Operating Characteristic (ROC) curve of miR-16 and miR-155 exhibited a significant distinguishing efficiency with an AUC value of 1 (95% CI, 1 to 1) and 0.967 (95% CI, 0.92-1.04) respectively. Following the therapy, the levels of miR-16 and miR-155 returned to those observed in healthy subjects. In patients with MDR TB, miR-155 was lower as compared to healthy controls and TB treated group but higher as compared to TB naïve patients. miR-16 levels were lowest in serum of MDR TB patients compared to TB naïve, TB treated group and healthy controls. In conclusion, miR-16 and miR-155 in serum may act as surrogate biomarker for studying TB infection, progression of therapy and MDR TB. Copyright © 2016 Elsevier Ltd. All rights reserved.

In this study, we aimed to explain the role of apelin-13 on body weight, food and water intake with serum leptin, ghrelin, neuropeptid Y (NPY) and peptid YY (PYY) levels in male rat. Thirty-two Sprague-Dawley male rats were used for the study. The rats were injected SP (0.9 %) intraperitoneally (i.p) in the control group and 30 (AP30), 100 (AP100) and 300 (AP300) µg/kg apelin-13 in the study groups, respectively, 10 min before the transition to dark period, for 10 days. During the experimental period, with light and dark periods of food and water intake, body weights were recorded in rats. Rats were euthanized and serum samples were obtained. In serum samples leptin, ghrelin, NPY and PYY levels were measured with specific ELISA kit. Apelin-13 was increased body weights in all three (AP30, AP100 and AP300) groups compared with the control group. AP100 and AP300 groups had increased food intake in the dark and the cumulative period, but in the light period food intake values were not significantly increased (p > 0.05). As for the value of water intake, compared with the control group, all dose of apelin-13 increased water intake during the dark and the cumulative period. There was no significant change in water intake in the light period. On the other hand, compared with the control group, serum leptin levels were found to increase in the groups administered 100 and 300 µg/kg of apelin-13 (p Ghrelin levels were found high in all groups treated with apelin-13. Serum levels of NPY decreased only in the 300 µg/kg apelin-13 treated group (p 0.05). Apelin-13 increases body weight in rats as well as food and water intake (dark and cumulative period). Additionally, ghrelin can mediate the orexigenic effect of apelin-13 in the regulation of food intake (Fig. 4, Ref. 37).

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

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

Directory of Open Access Journals (Sweden)

Masato Furuhashi

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

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

Full Text Available Objective: This study aims to determine the association of dyslipidemia and increased insulin resistance (IR with increased breast cancer (BC risk. Materials and Methods: The study group comprised 110 premenopausal and 143 postmenopausal, untreated female BC patients in the age range of 29–72 years. Control group consisted of 117 premenopausal and 141 postmenopausal healthy females in the age range of 23–75. Approximately 8-ml blood samples were drawn to measure various biochemical parameters. Serum glucose, total cholesterol, triglyceride (TG, and high-density lipoprotein-cholesterol were measured. Very low-density lipoprotein-cholesterol (VLDL-C and LDL-C were calculated using Friedewald's formula. Serum insulin and serum CA 15-3 were estimated by immune enzymatic assay. IR was assessed using homeostasis model assessment IR index (HOMA-IR. Results: Clinical variables in the case and control groups were compared using the unpaired Student's t-test. The crude and adjusted odds ratios (ORs and 95% confidence intervals (CIs were calculated by binary logistic regression analysis. Pearson's correlation analysis was used to determine the association between CA 15-3 and variables of interest. Total cholesterol, TG, LDL, VLDL, serum glucose, serum insulin, HOMA-IR, and serum CA 15-3 were significantly higher (P < 0.001 in BC patients compared to those in controls. Significant adjusted ORs with 95% CI were found to be fasting glucose, total cholesterol, and TGs. We also found a significant positive correlation between total cholesterol, TG, LDL, serum glucose, serum insulin, HOMA-IR, and serum CA 15-3. Conclusion: This study confirms the association between dyslipidemia, IR, and increased BC risk.

Serum C-Reactive Protein (CRP), Target for Therapy or Trouble?

Kraus, Virginia B; Jordan, Joanne M

2007-02-07

High sensitivity serum C-reactive protein (hs-CRP) has come into clinical use as a marker of risk for cardiovascular disease (CVD). In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs) for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

A low-grade systemic inflammatory status originating from periodontal infection has been proposed to explain the association between periodontal disease and systemic conditions, including adverse obstetric outcomes. The aim of this study was to evaluate the effect of periodontal therapy during pregnancy on the gingival crevicular fluid and serum levels of six cytokines associated with periodontal disease and preterm birth. A subsample of 60 women (18-35 years of age) up to 20 gestational weeks, previously enrolled in a larger randomized clinical trial, was recruited for the present study. Participants were randomly allocated to receive either comprehensive nonsurgical periodontal therapy before 24 gestational weeks (n = 30, test group) or only one appointment for supragingival calculus removal (n = 30, control group). Clinical data, and samples of blood and gingival crevicular fluid, were collected at baseline, at 26-28 gestational weeks and 30 d after delivery. The levels of interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12p70 and tumor necrosis factor-α were analyzed by flow cytometry. After treatment, a major reduction in periodontal inflammation was observed in the test group, with bleeding on probing decreasing from 49.62% of sites to 11.66% of sites (p Periodontal therapy significantly reduced the levels of IL-1β and IL-8 in gingival crevicular fluid (p periodontal therapy during pregnancy successfully reduced periodontal inflammation and gingival crevicular fluid cytokine levels, it did not have a significant impact on serum biomarkers. © 2012 John Wiley & Sons A/S.

Full Text Available Aim: To determine the serum variations of two major acute phase proteins, serum amyloid A (SAA and haptoglobin (Hp levels in crossbred endometritis cows following pre and post immunomodulation therapy. Materials and Methods: 21 endometritis cows were randomly assigned to three groups (n=7 and treated with three different immunomodulators while seven healthy cows served as control. Uterine flushing collected from all animals was subjected to bacteriological study and serum samples were analyzed for SAA and Hp by sandwich ELISA method. Results: Escherichia coli was most prevalent Gram-negative bacteria (6.02 × 106 CFU/ml while Staphylococcus (0.86 × 106 CFU/ml and Streptococcus (0.52 × 106 CFU/ml were most predominant Gram-positive species isolated from uterine flushing. The pre-treatment SAA values (μg/ml varied significantly (p<0.01 between the treatment groups whereas no difference was observed in post-treatment groups. No significant difference (p<0.01 was observed for Hp values between the treatment groups, but the mean SAA (μg/ml and Hp (μg/ml levels were significantly (p<0.01 higher in pre-treatment when compared to post-treatment within the groups. Conclusion: In the diagnosis and monitoring of bovine endometritis, both SAA and Hp might serve as reliable biomarkers.

In early breast cancer patients, the effects of hormonal therapy (tamoxifen and aromatase inhibitors) on plasma fibroblast growth factor 21 (FGF-21), lipid levels and body composition have not yet been investigated. Therefore, we aimed to analyze the relationship between FGF-21 and body composition as well as the effects of tamoxifen and aromatase inhibitors on plasma lipid levels, FGF-21, and body composition. A total of 72 patients were treated with either tamoxifen or aromatase inhibitors due to their menopausal status after adjuvant radiotherapy. Each patient was followed-up over a period of 1 year. Changes in body composition and serum lipid profile, glucose and FGF-21 levels were evaluated. We recorded the type of hormonal therapy, body mass index, waist-to-hip ratio, lipid profile, and FGF-21 levels both at the beginning and after 12 months. There was a statistically significant decrease in serum FGF-21 levels after 12 months of adjuvant endocrine therapy (46 ± 19.21 pg/ml vs. 30.99 ± 13.81 pg/ml, pbody water (pbody composition, glucose, lipid profile and FGF-21 were similar in tamoxifen and aromatase inhibitor groups. A positive correlation was found between basal weight, fat mass, fat-free mass and serum FGF-21 levels; however, the correlation was maintained only for the fat-free mass at the 12th month. As part of the present study, we suggest that both tamoxifen and aromatase inhibitors can reduce FGF-21 levels independently of body compositions, and these drugs can provide antihyperlipidemic, antidiabetic and cardio-protective effects. We also recommend that serum FGF-21 level can be utilized as a tumor biomarker in early-stage breast cancer and for monitoring purposes. FGF-21 levels may help physicians estimate prognosis, too. Further studies with larger populations may shed light on the role of FGF-21 in breast cancer.

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

Serum carcinoembryonic antigen (CEA) and serum squamous cell carcinoma antigen (SCC Ag) levels have been reported to be useful as prognostic factors, indicators of clinical response, and predictors for recurrence in patients with lung cancer treated by surgery or chemotherapy. We investigated whether pretreatment serum CEA and SCC Ag levels were useful as independent prognostic factors in patients with stage I to III non-small cell lung cancer who were treated with radiation therapy alone. The serum CEA and SCC Ag levels were measured in 158 and 47 patients, respectively, before radiation therapy. Serum CEA and SCC Ag levels were measured by sandwich radioimmunoassay using the CEA-RIA (radioimmunoassay) kit and the SCC-RIA kit. Serum CEA and SCC Ag levels were above reference values in 19% and 30% of the patients, respectively. The 5-year survival rates were significantly better for patients with a negative SCC Ag result than for those with positive SCC Ag levels (p=0.0001), though no significant difference in survival rates was seen by CEA positivity (p=0.25). SCC Ag positivity (p=0.0006) and stage (p=0.04) were the important prognostic factors, as determined by multivariate analyses. Pretreatment serum SCC Ag level may be useful as an independent prognostic factor in patients with stage I to III non-small cell lung cancer who are treated with radiation therapy alone. (author)

Several epidemiological studies have shown the inverse association of lithium levels in drinking water and suicide rates; however, it is necessary to perform a clinical study dealing with individual patients. We analyzed 199 patients including 31 patients with suicide attempts, 21 patients with self-harm, and 147 control patients. All were transferred to a university emergency department suffering from intoxication or injury, were aged 20 or more years, and were alive at the start of the study. The exclusion criteria consisted of suffering from schizophrenia and a past or present history of lithium therapy. These exclusions were applied because it is difficult to determine whether their suicide attempt was induced by the intent to end their life or by psychotic symptoms such as auditory hallucinations, and if the patient had received lithium therapy, the association between the small amount of lithium taken from drinking water and food and serum lithium levels cannot be detected. There was a significant difference (p = 0.043) between the three groups whereby patients with suicide attempts had significantly lower lithium levels than control patients (p = 0.012) in males but not females. Multivariate logistic regression analysis with adjustment for age and gender revealed that patients with suicide attempts had significantly lower lithium levels than control patients (p = 0.032, odds ratio 0.228, 95% CI 0.059-0.883). The limitations of the present study are the nature of observational research which cannot reveal a causal relationship and the relatively small number of subjects. The present findings suggest that higher serum lithium levels may be protective against suicide attempts in lithium therapy-naive individuals.

YKL-40 is an inflammatory glycoprotein associated with atherosclerosis, cardiovascular disease, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of the study was to assess serum YKL-40 level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and treatment. A total of 37 individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after 2 weeks of therapy. Serum YKL-40 concentrations were evaluated by enzyme-linked immunosorbent assay (ELISA). The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and topical therapy. Median YKL-40 serum levels were significantly increased in psoriatic patients in comparison to the controls (p psoriasis and inflammation in psoriatic patients, but not a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of the treatment.

Metabolic encephalopathy is a rare but serious complication of valproic acid (VPA) therapy that usually presents with impaired consciousness or increased seizure frequency. Although it has been suggested that topiramate (TPM) increases the risk of VPA-induced encephalopathy, the additional risk in patients receiving TPM therapy has not been evaluated. We reviewed all adult patients who took VPA between January 2005 and February 2009 at the Seoul National University Hospital and identified patients with VPA-induced encephalopathy based on clinical and electroencephalography (EEG) data. Information on sex, age, serum ammonia level, serum VPA level, liver function test, and EEG was collected from patient registry and medical data. We enrolled 8,372 patients who received VPA therapy and 1,236 patients who received VPA/TPM combination therapy. We identified 11 patients with VPA-induced encephalopathy (0.13%), 7 of whom received a combination therapy of VPA and TPM. The odds ratio of VPA-induced encephalopathy with TPM over that without TPM was 10.16. There were no significant differences in sex distribution, number of antiepileptic agents, ammonia level, VPA serum level, underlying diseases, dosage of VPA, duration of VPA treatment, treatment of encephalopathy, and outcomes between the two groups. Our study showed that the prevalence of VPA-induced encephalopathy is approximately 0.1% among patients treated with VPA and that the risk of this condition, although still low, can increase by approximately 10 times in the presence of TPM therapy. Based on these results, we suggest that TPM should be carefully used in patients receiving VPA treatment. Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.

A liquid chromatography/time-of-flight mass spectrometry (LC/TOF-MS)-based metabolomics approach was employed to identify endogenous metabolites as potential biomarkers for thioacetamide (TAA)-induced liver injury. TAA (10 and 30 mg/kg), a well-known hepatotoxic agent, was administered daily to male Sprague–Dawley (SD) rats for 28 days. We then conducted untargeted analyses of endogenous serum and liver metabolites. Partial least squares discriminant analysis (PLS-DA) was performed on serum and liver samples to evaluate metabolites associated with TAA-induced perturbation. TAA administration resulted in altered levels of bile acids, acyl carnitines, and phospholipids in serum and in the liver. We subsequently demonstrated and confirmed the occurrence of compromised bile acid homeostasis. TAA treatment significantly increased serum levels of conjugated bile acids in a dose-dependent manner, which correlated well with toxicity. However, hepatic levels of these metabolites were not substantially changed. Gene expression profiling showed that the hepatic mRNA levels of Ntcp, Bsep, and Oatp1b2 were significantly suppressed, whereas those of basolateral Mrp3 and Mrp4 were increased. Decreased levels of Ntcp, Oatp1b2, and Ostα proteins in the liver were confirmed by western blot analysis. These results suggest that serum bile acids might be increased due to the inhibition of bile acid enterohepatic circulation rather than increased endogenous bile acid synthesis. Moreover, serum bile acids are a good indicator of TAA-induced hepatotoxicity. - Highlights: • Endogenous metabolic profiles were assessed in rat after treatment of thioacetamide. • It significantly increased the levels of bile acids in serum but not in the liver. • Expression of the genes related to bile acid secretion and reuptake was decreased. • Increased serum bile acids result from block of enterohepatic circulation of bile acids.

Full Text Available About one-fifth of patients treated with levothyroxine have serum thyrotropin (TSH above target concentrations but, in approximately 15% of them, the cause of this TSH insufficient normalization remains unknown. We report the cases of two regularly menstruating women with known thyroid disease who had TSH levels consistently >3 mU/L (and sometimes above target levels during mid-cycle, but consistently lower serum levels during the follicular and luteal phases of menstrual cycle. A major TSH release by the thyrotrophs in response to high circulating levels of estradiol (E2 at mid-cycle may increase levels of TSH compared to other phases of the cycle. The increased TSH can be misinterpreted as refractory hypothyroidism if the woman is under L-T4 replacement therapy or as subclinical hypothyroidism if the woman is not. Our findings might have important implications for diagnosis and management of thyroid disease, suggesting to request serum TSH measurements outside of the periovulatory days.

Hypoparathyroidism: Replacement Therapy with Parathyroid Hormone

Directory of Open Access Journals (Sweden)

Full Text Available Hypoparathyroidism (HypoPT is characterized by low serum calcium levels caused by an insufficient secretion of parathyroid hormone (PTH. Despite normalization of serum calcium levels by treatment with activated vitamin D analogues and calcium supplementation, patients are suffering from impaired quality of life (QoL and are at increased risk of a number of comorbidities. Thus, despite normalization of calcium levels in response to conventional therapy, this should only be considered as an apparent normalization, as patients are suffering from a number of complications and calcium-phosphate homeostasis is not normalized in a physiological manner. In a number of recent studies, replacement therapy with recombinant human PTH (rhPTH(1-84 as well as therapy with the N-terminal PTH fragment (rhPTH(1-34 have been investigated. Both drugs have been shown to normalize serum calcium while reducing needs for activated vitamin D and calcium supplements. However, once a day injections cause large fluctuations in serum calcium. Twice a day injections diminish fluctuations, but don't restore the normal physiology of calcium homeostasis. Recent studies using pump-delivery have shown promising results on maintaining normocalcemia with minimal fluctuations in calcium levels. Further studies are needed to determine whether this may improve QoL and lower risk of complications. Such data are needed before replacement with the missing hormone can be recommended as standard therapy.

Tumor-induced osteomalacia (TIO) is an acquired hypophosphatemic metabolic bone disorder that can be cured by removing or ablating the offending tumor. However, when the tumor cannot be localized, lifelong therapy with oral phosphate and calcitriol or cinacalcet with close monitoring is required. A 56-year-old man was diagnosed with TIO in 1990. Initial therapy consisted of oral phosphate and calcitriol with symptomatic and biochemical improvement and healing of osteomalacia. Eight years later, hypercalcemic hyperparathyroidism developed, requiring subtotal parathyroidectomy with a transient increase in serum phosphate and normalization of serum calcium and PTH. Recurrent hypercalcemic hyperparathyroidism developed after 10 years of medical therapy. A deliberate total parathyroidectomy produced a prompt rise in serum phosphate into the normal range > 3.0 mg/dL and remained normal during the next 4 years of follow-up, despite continued very high serum fibroblast growth factor-23 levels throughout the 23-year follow-up. We report an unusual case of a TIO patient with long-term follow-up who developed recurrent hypercalcemic hyperparathyroidism on long-term oral phosphate therapy. Deliberate total parathyroidectomy normalized serum phosphate despite persistently elevated fibroblast growth factor-23 levels. Total parathyroidectomy offers a potentially novel therapy in some patients with TIO in whom medical therapy is not feasible or the tumor is unresectable.

Previous studies have shown a positive effect of zinc as an adjunctive therapy on reducing depressive symptoms. However, to our knowledge, no study has examined the effect of zinc monotherapy on mood. The aim of the present study was to determine the effects of zinc monotherapy on depressive symptoms and serum brain-derived neurotrophic factor (BDNF) levels in overweight or obese subjects. Fifty overweight or obese subjects were randomly assigned into two groups and received either 30 mg zinc or placebo daily for 12 weeks. At baseline and post-intervention, depression severity was assessed using Beck depression inventory II (BDI II), and serum BDNF and zinc levels were determined by enzyme-linked immunosorbent assay and atomic absorption spectrophotometry, respectively. The trial was completed with 46 subjects. After a 12-week supplementation, serum zinc and BDNF levels increased significantly in the zinc-supplemented group compared with the placebo group. BDI scores declined in both the groups at the end of the study, but reduction in the zinc-supplemented group was significantly higher than the placebo group. More analysis revealed that following supplementation, BDI scores decreased in subgroup of subjects with depressive symptoms (BDI ≥ 10) (n = 30), but did not change in the subgroup of non-depressed subjects (BDI BDNF levels and depression severity in all participants. Interestingly, a significant positive correlation was found between serum BDNF and zinc levels at baseline. Zinc monotherapy improves mood in overweight or obese subjects most likely through increasing BDNF levels.

We aimed to study the effect of long-term supplementation of B-vitamins on folate forms in serum and whole blood (WB) in elderly German subjects. 59 participants (mean age 67 years) were randomized to daily receive either vitamin D3 (1200 IU), folic acid (500 μg), vitamin B12 (500 μg), vitamin B6 (50 mg), and calcium carbonate (456 mg) or vitamin D3 plus calcium carbonate. Serum and WB folate forms were measured before and after 6 and 12 months. B-vitamins supplementation for 6 months led to higher concentrations of 5-methyltetrahydrofolate (5-methylTHF) in serum (mean 49.1 vs. 19.6 nmol/L) and WB (1332 vs. 616 nmol/L). Also non-methyl-folate concentrations in serum and WB were higher after 6 months with B-vitamins supplementation. Unmetabolized folic acid (UFA) increased after supplementation. tHcy concentration was lowered after 1 year of B-vitamin supplementation (mean 13.1 vs. 9.6 μmol/L). A stronger reduction of tHcy after 1 year was found in participants who had baseline level >12.5 μmol/L (mean 17.0 vs. 11.9 μmol/L) compared to those with baseline tHcy lower than this limit (mean 9.1 vs. 7.4 μmol/L). In contrast, the increases in serum and WB 5-methylTHF were comparable between the two groups. One year B-vitamins supplementation increased the levels of 5-methylTHF and non-methyl-folate in serum and WB, normalized tHcy, but caused an increase in the number of cases with detectable UFA in serum. Lowering of tHcy was predicted by baseline tHcy, but not by baseline serum or WB 5-methylTHF.

Background and purpose:To determine the effect of curative radiation therapy (46-50 Gy) on the sex hormone levels in male rectal cancer patients. Materials and methods:Twenty-five male rectal cancer patients (mean age 65 years), receiving pelvic radiation therapy (2 Gyx23-25 fractions in 5 weeks) were included. Serum testosterone, FSH and LH were determined before start of treatment, at the 10th and 25th fractions, and 4-6 weeks after completed radiotherapy. The testicular dose was determined by thermoluminescent dosimetry. Results:Five weeks of radiation therapy (46-50 Gy) resulted in a 100% increase in serum FSH, a 70% increase in LH, and a 25% reduction in testosterone levels. After treatment, 35% of the patients had serum testosterone levels below lower limit of reference. The mean radiation dose to the testicles was 8.4 Gy. A reduction in testosterone values was observed already after a mean dose of 3.3 Gy (10th fraction). Conclusion:Radiation therapy (46-50 Gy) for rectal cancer resulted in a significant increase in serum FSH and LH and a significant decrease in testosterone levels, indicating that sex hormone production is sensitive to radiation exposure in patients with a mean age of 65 years

The effects of betamethasone on thyroid autoantibody responses and outcome of radioiodine therapy were determined over a period of 1 yr in a prospective randomized study of 40 patients with Graves' disease. Twenty patients were given placebo tablets, and 20 patients were treated with betamethasone from 3 weeks before until 4 weeks after 131 I therapy. At the time of inclusion in the study, the mean serum concentrations of TSH receptor antibodies, thyroid peroxidase antibodies, and thyroglobulin antibodies (TgAb) were increased in both groups. Three weeks of treatment with betamethasone reduced the thyroid peroxidase antibody and TgAb titers as well as the serum concentrations of thyroid hormones. A decrease in the TSH receptor antibody level was not statistically significant. After radioiodine therapy, transient increases in thyroid autoantibody levels were observed. The titers of the different antibodies generally changed in parallel. In some patients a detectable level of a given antibody was found only after the radioiodine treatment, and in two cases, TgAb did not appear at all, although the two other antibodies increased temporarily. Betamethasone delayed, but did not abolish, the 131 I-induced antibody peaks. Betamethasone also caused a reduction in the total serum immunoglobulin G, a reduction which persisted throughout the study period. When the study ended, 17 patients given placebo and 9 patients given betamethasone were receiving replacement therapy due to the development of hypothyroidism. These patients at this point in time had lower antibody levels than those not requiring T4. The results of this study demonstrate that betamethasone reduces and modifies the thyroid autoantibody responses as well as the outcome of radioiodine therapy in patients with Graves' disease

Objective: To investigate the relationship between serum tumor necrosis factor-α (TNF-α) levels and insulin resistance (IR) in patients with essential by pertension. Methods: Serum TNF-α and free insulin (fINS)levels were measured with RIA in 41 patients with essential hypertension and 38 controls. Insulin resistance was calculated with insulin resistance index (HOMA-IR). Results: The serum TNF-α levels were significantly higher in patients with essential hypertension than those in the controls (P<0.001). The HOMA-IR was also significantly higher in hypertension group than that in controls (P<0.001). Serum TNF-α levels was positively correlated with BMI, HOMA-IR and SBP both in hypertension group and control group (P<0.05). Conclusion: Serum TNF-α level was increased in hypertensive patients and positively correlated with obesity and IR. (authors)

Serum albumin concentration is associated with both type 2 diabetes and metabolic syndrome (MetS). We sought to investigate whether baseline serum albumin and change in serum albumin could be independent risk factors for prediabetes in subjects without MetS. We further examined the effect of serum albumin on progression to overt diabetes in subjects who developed prediabetes. Among 10,792 participants without diabetes and MetS who consecutively underwent yearly health check-ups over six years, 9,807 subjects without incident MetS were enrolled in this longitudinal retrospective study. The risk of developing prediabetes (impared fasting glucose or hemoglobin A1c) was analyzed according to baseline and percent change in serum albumin concentration using Cox regression analysis. Serial changes in serum albumin concentration were measured from baseline to one year before prediabetes diagnosis, and then from the time of prediabetes diagnosis to progression to overt diabetes or final follow-up. A total of 4,398 incident cases of prediabetes developed during 35,807 person-years (median 3.8 years). The hazard ratio for incident prediabetes decreased as percent change in serum albumin concentration (quartiles and per 1%) increased in a crude and fully adjusted model. However, baseline serum albumin concentration itself was not associated with prediabetic risk. Serum albumin levels kept increasing until the end of follow-up in prediabetic subjects who returned to normal glycemic status, whereas these measures did not change in prediabetic subjects who developed type 2 diabetes. Serum albumin concentration measured at the end of follow-up was the highest in the regression group, compared to the stationary (p = 0.014) or progression groups (p = 0.009). Increase in serum albumin concentration might protect against early glycemic deterioration and progression to type 2 diabetes even in subjects without MetS.

Background: Testosterone (T) is mainly excreted in the urine as testosterone glucuronide (TG). This glucuronidation is partly dependent on the UGT2B17 genotype, and TG excretion is therefore lower in men having the UGT2B17 deletion. However, the possible influence of UGT2B17 genotype on serum T...... during androgen therapy is unknown. We retrospectively investigated the possible association between the UGT2B17 gene polymorphism and serum T levels in hypogonadal men during Testosterone undecanoate (TU) substitution therapy. Subjects and Methods: Two hundred and seven patients treated with TU (Nebido...

HYPOLIPEMIC THERAPY AND LOW SERUM CHOLESTEROL CONCENTRATION

Full Text Available Low concentration of plasma lipoproteins (hypolipoproteinemia presents decreasing concentrations of all or particular lipids components. Classification of hypolipoproteinemia (hypoLP divides them into: primary (hereditary and secondary. Primary hipoLP are rare diseases and their main characteristic is disorder of apolipoproteins synthesis, which leads to low serum cholesterol concentration. Secondary hipoLP are presented in many diseases. They have diagnostic, prognostic significance and present good therapeutic marker. However, modern therapeutic approaches for aggressive lipid lowering pointed out many questions about physiological limits for cholesterol lowering. These approaches, also, open many questions about consequences of low serum concentration of total cholesterol and triglicerides.

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

It has been demonstrated that physical training increases serum brain-derived neurotrophic factor (BDNF) in healthy people. The aim of this study was to establish the effect of physical training on the basal serum level of the BDNF in the Parkinson's disease patients (PD patients) in relation to their health status. Twelve PD patients (mean ± S.E.M: age 70 ± 3 years; body mass 70 ± 2 kg; height 163 ± 3 cm) performed a moderate-intensity interval training (three 1-hour training sessions weekly), lasting 8 weeks. Basal serum BDNF in the PD patients before training amounted to 10,977 ± 756 pg x mL(-1) and after 8 weeks of training it has increased to 14,206 ± 1256 pg x mL(-1) (i.e. by 34%, P=0.03). This was accompanied by an attenuation of total Unified Parkinson's Disease Rating Scale (UPDRS) (P=0.01). The training resulted also in a decrease of basal serum soluble vascular cell adhesion molecule 1 (sVCAM-1) (P=0.001) and serum tumor necrosis factor-α (TNF-α) (P=0.03) levels. We have concluded that the improvement of health status of the Parkinson's disease patients after training could be related to the increase of serum BDNF level caused by the attenuated inflammation in those patients.

Mesenchymal Stromal Cells Cultured in Serum from Heart Failure Patients Are More Resistant to Simulated Chronic and Acute Stress

Full Text Available Despite regulatory issues surrounding the use of animal-derived cell culture supplements, most clinical cardiac cell therapy trials using mesenchymal stromal cells (MSCs still rely on fetal bovine serum (FBS for cell expansion before transplantation. We sought to investigate the effect of human serum from heart failure patients (HFS on cord blood MSCs (CB-MSCs during short-term culture under regular conditions and during simulated acute and chronic stress. Cell survival, proliferation, metabolic activity, and apoptosis were quantified, and gene expression profiles of selected apoptosis and cell cycle regulators were determined. Compared to FBS, HFS and serum from healthy donors (CS showed similar effects by substantially increasing cell survival during chronic and acute stress and by increasing cell yields 5 days after acute stress. Shortly after the termination of acute stress, both HFS and CS resulted in a marked decrease in apoptotic cells. Transcriptome analysis suggested a decrease in TNF-mediated induction of caspases and decreased activation of mitochondrial apoptosis. Our data confirm that human serum from both healthy donors and heart failure patients results in increased cell yields and increased resistance to cellular stress signals. Therefore, we consider autologous serum a valid alternative to FBS in cell-based therapies addressing severe heart disease.

Objectives : Antimicrobial therapy is one of the cornerstones of orthopaedic implant-related infections (OIRI) treatment. Infections with Gram-positive bacteria are often treated with vancomycin, penicillin or clindamycin. A recent IDSA guideline suggests increasing the dose of vancomycin to increase the trough vancomycin target serum concentrations. This is deemed necessary because of an observed decrease in vancomycin susceptibility among Gram-positive bacteria. However, elevated vancomycin concentrations are correlated with the risk of nephrotoxicity, especially with prolonged therapy. Compared to most countries, rates of resistance against antibiotics among bacteria in the Netherlands are lower for currently available antibiotics, therefore lower target concentrations of vancomycin are probably efficacious for the treatment of infections. In this study we evaluated the efficacy and safety of long-term conventionally dosed vancomycin therapy, as an initial therapy for OIRI, and compared this with long-term penicillin and clindamycin therapy, as initial therapy, in patients with Gram-positive orthopaedic implant-related infections. Methods : A retrospective, observational study was conducted in 103 adult patients treated for OIRI, with vancomycin, penicillin or clindamycin for at least 10 days. The target trough serum concentration of vancomycin was 10-15 mg/l. Results : 74% of our patients were treated successfully with vancomycin, as initial therapy, (no reinfection within 1 year) versus 55% of our patients treated with either an antibiotic of the penicillin class (mostly flucloxacillin) or clindamycin (p=0.08), as initial therapy. For patients treated with vancomycin we observed a serum creatinine increase of 6 μmol/l, for patients treated with either an antibiotic of the penicillin class or clindamycin the serum creatinine increase was 4 μmol/l (p=0.395). Conclusions : In our population of patients with OIRI long-term treatment with conventionally dosed

Methods: A total of 92 patients with ACS were randomly divided into observation group (47 cases and control group (45 cases. The control group was given Atorvastatin (10mg/d based on the conventional therapy, while the observation group was given Atorvastatin at an intensive dose (40 mg/d based on the conventional therapy. Half a month later, the changes of IL-6, IL-8, hs-CRP, TNF-α, TXB2, GMP-140, PAI-1 and t-PA were observed and compared between the two groups. Results: After treatment, the inflammatory factors (IL-6, IL-8, hs-CRP and TNF-α and the indicators of platelet activity (TXB2, GMP-140 and PAI-1 were obviously decreased, while the indicator of fibrinolytic activity (t-PA was apparently increased in the two groups. Besides, the amplitudes of change referring to these indicators in the observation group were bigger than those in the control group after treatment, and the differences were statistically significant. Conclusion: The intensive therapy with the administration of Atorvastatin at a dose of 40 mg/d was better than the conventional therapy (Atorvastatin: 10 mg/d in aspects of reducing inflammatory factors, inhibiting platelet activity and correcting the high coagulation state of fibrinolytic system.

AHPO was characterized initially and during the course of disease by clinical findings. C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total and differential white blood cell (WBC) count, BSC, and plain radiography. CRP was the most effective serum parameter for follow-up of disease. The first sign of BSC to signal adequate response to antibiotic treatment was the decrease or normalization of hyperperfusion. Escape from therapy or poor prognosis, even when the serum parameters were normalized, was signaled by the recurrence of focal hyperperfusion and the persistent or increasing local uptake ratios on the 3-h-image over 6 weeks during a course of antibiotic treatment. Antibiotic treatment masks the clinical presentation, and the radiographic findings, causes non-characteristic laboratory findings, but do not prevent the scintigraphic visualization; BSC and serum parameters used in the right completion are the most successful and efficient modalities for follow-up of AHPO. Maintenance of antibiotic therapy should be done until BSC findings have reverted to normal. (orig.) [de

This study evaluates serum creatine kinase isoenzyme activity in children with osteogenesis imperfecta to determine its usefulness as a biochemical marker during treatment with bisphosphonate. The changes of creatine kinase (CK) isoenzyme activity during and after discontinuation therapy were observed. These results could be useful in addressing over-treatment risk prevention. The brain isoenzyme of creatine kinase (CKbb) is highly expressed in mature osteoclasts during osteoclastogenesis, thus plays an important role in bone resorption. We previously identified high serum CKbb levels in 18 children with osteogenesis imperfect (OI) type 1 treated for 1 year with bisphosphonate (neridronate). In the present study, serum CK isoenzymes were evaluated in the same children with continuous versus discontinued neridronate treatment over a further 2-year follow-up period. This study included 18 children with OI type 1, 12 with continued (group A) and 6 with ceased (group B) neridronate treatment. Auxological data, serum biochemical markers of bone metabolism, bone mineral density z-score, and serum total CK and isoenzyme activities were determined in both groups. Serum CKbb was progressively and significantly increased in group A (p < 0.004) but rapidly decreased to undetectable levels in group B. In both groups, the cardiac muscle creatine kinase isoenzyme (CKmb) showed a marked decrease, while serum C-terminal telopeptide (CTx) levels were almost unchanged. This study provides evidence of the cumulative effect of neridronate administration in increasing serum CKbb levels and the reversible effect after its discontinuation. This approach could be employed for verifying the usefulness of serum CKbb as a biochemical marker in patients receiving prolonged bisphosphonate treatment. Moreover, the decreased serum CKmb levels suggest a systemic effect of these drugs.

Adult Growth Hormone Deficiency (AGHD) is correlated to many adverse effects on metabolism and increased cardiovascular risk. Pregnancy-associated plasma protein-A (PAPP-A) is a protease that promotes IGF-I availability in vascular tissues in recent study, and PAPP-A levels have been proposed as an early predictor of cardiac events. The aim of our study was to compare PAPP-A levels in AGHD patients with that of healthy adult subjects to determine if there is a relationship between serum PAPP-A and glucose and lipid metabolism. Twenty AGHD patients and 20 healthy, age-matched and weight-matched persons were chosen for the study. Their weight, height, blood pressure, body mass index (BMI), body fat percentage, waist and hip circumference, and waist-hips ratio were assessed. An oral glucose tolerance test was performed and venous blood was collected from the each patient's cubital vein for biochemical analysis. Serum PAPP-A level in AGHD patients was significantly higher than that of the control group [(7.62 ± 1.62 vs. 6.54 ± 1.31) p < 0.05], and PAPP-A was positively correlated to age, BMI, waist circumference and so on. After adjusting for the waist circumference, waist-hip ratio, 2 h postprandial blood glucose, triglycerides, the serum PAPP-A in AGHD patients was positively correlated to the BMI (r = 0.728, p < 0.05) and fasting insulin (r = 0.433, p < 0.05). In a multiple step-wise regression analysis, BMI, 2 h postprandial glucose, fasting insulin, HOMA-IR were independently associated with serum PAPP-A in AGHD patients. The increase in serum PAPP-A levels is associated with abnormal glucose metabolism and increased risk of atherosclerosis in AGHD patients.

The aim of the present study was to compare blood serum kynurenic acid (KYNA) concentrations measured before ECT and after 1, 6 and 12 electroconvulsive treatment (ECT) sessions in patients with diagnoses of recurrent depressive disorder (RDD), depression in bipolar disorder (DBD) and schizoaffective disorder (SAD). The study group comprised of 50 patients with ICD-10 diagnoses of RDD, DBD and SAD. Blood serum KYNA concentrations were determined and clinical assessment was performed using the MADRS and the GAF scale. Significant differences were found in blood serum KYNA levels between RDD, DBD and SAD patients treated with electroconvulsive therapy and healthy controls: 1) KYNA concentrations in DBD patients measured before ECT and after 12 ECT sessions were significantly lower than in the control group; 2) KYNA concentrations in the serum of RDD patients measured before ECT and after one and 12 ECT sessions were significantly lower than in the control group, while those measured after 6 ECT session did not differ significantly from KYNA concentrations in healthy controls; 3) higher pre-treatment blood serum concentrations of KYNA in DBD patients correlated with a higher number of illness phases and poorer general functioning before treatment; 4) significant relationships were found between higher blood serum concentrations of KYNA in RDD patients after 1 ECT session and male gender, and between higher KYNA concentrations after 6 ECT sessions and increased depression and poorer functioning before treatment in those patients. Results show that KYNA concentrations in all diagnostic groups were lower before ECT (not statistically significant for the SAD group) and that there were no significant changes in those concentrations (compared with the baseline) during ECT.

Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid (n-3 PUFA) that has been shown to raise seizure thresholds in the maximal pentylenetetrazole model following acute subcutaneous (s.c.) administration in rats. Following s.c. administration, however, the dose-response relationship for DHA has shown an inverted U-pattern. The purposes of the present experiment were as follows: (1) to determine the pattern of serum unesterified concentrations resulting from the intravenous (i.v.) infusions of various doses of DHA, (2) to determine the time course of these concentrations following the discontinuation of the infusions, and (3) to determine whether seizure protection in the maximal PTZ model would correlate with serum unesterified DHA levels. Animals received 5-minute i.v. infusions of saline or 25, 50, 100, or 200mg/kg of DHA via a cannula inserted into one of the tail veins. Blood was collected during and after the infusions by means of a second cannula inserted into the other tail vein (Experiment 1). A separate group of animals received saline or 12.5-, 25-, 50-, 100-, or 200 mg/kg DHA i.v. via a cannula inserted into one of the tail veins and were then seizure-tested in the maximal PTZ model either during infusion or after the discontinuation of the infusions. Slow infusions of DHA increased serum unesterified DHA concentrations in a dose-dependent manner, with the 200-mg/kg dose increasing the concentration approximately 260-fold compared with saline-infused animals. Following discontinuation of the infusions, serum concentrations rapidly dropped toward baseline, with half-lives of approximately 40 and 11s for the 25-mg/kg dose and 100-mg/kg dose, respectively. In the seizure-tested animals, DHA significantly increased latency to seizure onset in a dose-dependent manner. Following the discontinuation of infusion, seizure latency rapidly decreased toward baseline. Overall, our study suggests that i.v. infusion of unesterified DHA results in

Full Text Available Background and aims. Visfatin, mainly secreted by visceral adipose tissue, especially by macrophages, plays an impor-tant role in regulating the defense and immune functions, and functions as a growth factor, a cytokine, an enzyme and more importantly as a proinflammatory mediator. The aim of the present study was to evaluate the effect of non-surgical perio-dontal treatment on serum and salivary levels of visfatin in patients with generalized moderate-to-severe chronic periodonti-tis. Materials and methods. Eighteen patients with generalized moderate-to-severe chronic periodontitis were selected based on periodontal parameters of gingival index (GI, probing pocket depth (PPD, clinical attachment level (CAL and radio-graphic parameters. Serum and salivary samples were collected at baseline and one month following non-surgical periodon-tal therapy (scaling and root planing ([SRP]. Visfatin levels were measured using an ELISA kit. Data were analyzed by SPSS 15, using paired t-test and Pearson’s correlation coefficient. Results. Mean salivary and serum levels of visfatin significantly decreased after non-surgical periodontal treatment (P<0.05. Changes in salivary visfatin levels were more prominent. Conclusion. According to the findings of this study it seems that there is a direct relationship between periodontal tissue inflammation and disease activity with salivary and serum visfatin levels.

To determine the significance of increased serum direct bilirubin level for lymph node metastasis (LNM) in Chinese rectal cancer patients, after those with known hepatobiliary and pancreatic diseases were excluded. A cohort of 469 patients, who were treated at the China-Japan Friendship Hospital, Ministry of Health (Beijing, China), in the period from January 2003 to June 2011, and with a pathological diagnosis of rectal adenocarcinoma, were recruited. They included 231 patients with LNM (49.3%) and 238 patients without LNM. Follow-up for these patients was taken through to December 31, 2012. The baseline serum direct bilirubin concentration was (median/inter-quartile range) 2.30/1.60-3.42 μmol/L. Univariate analysis showed that compared with patients without LNM, the patients with LNM had an increased level of direct bilirubin (2.50/1.70-3.42 vs 2.10/1.40-3.42, P = 0.025). Multivariate analysis showed that direct bilirubin was independently associated with LNM (OR = 1.602; 95%CI: 1.098-2.338, P = 0.015). Moreover, we found that: (1) serum direct bilirubin differs between male and female patients; a higher concentration was associated with poor tumor classification; (2) as the baseline serum direct bilirubin concentration increased, the percentage of patients with LNM increased; and (3) serum direct bilirubin was associated with the prognosis of rectal cancer patients and higher values indicated poor prognosis. Higher serum direct bilirubin concentration was associated with the increased risk of LNM and poor prognosis in our rectal cancers.

improved mood in all depressive patients. In addition, placebo treated patients during PSD exhibited a significant increase of serum cortisol levels during PSD when compared to morning peak levels at 8 am between day one and two. There was no serum cortisol increase in the modafinil treated group during PSD intervention. Conclusions : Altogether, it seems that a diurnal pattern of serum BDNF during the day is necessarily associated with acute and response after two weeks in terms of partial sleep deprivation independently from additional treatment (modafinil vs. placebo. BDNF levels peaking in the morning and declining during the day seem to be favourable for an antidepressant response. Therefore, BDNF expression profile in serum at baseline could be used as possible predictor for therapy outcome.

Since cationic liposome was first developed as a lipofection reagent, a drawback has been noted in that the efficiency of lipofection decreases dramatically after addition of serum to the lipofection medium. This drawback hampers the application of cationic liposome for systematic delivery of genes. In the present studies, we found that the effect of serum on DC-chol liposome-mediated lipofection is dependent on the charge ratio of liposome to DNA. Serum inhibited lipofection activity of the lipoplex at low charge ratios, whereas it enhanced the lipofection activity at high charge ratios. This phenomenon was observed using DOTAP/DOPE but not lipofectamine. Measurement of cellular association of DNA showed that serum could reduce the binding of lipoplex to cells at all tested charge ratios, i.e. 0-10.6. Removal of negatively charged proteins from serum by DEAE Sephacel column abolished the inhibitory effect of serum on lipofection. The fraction contained only negatively charged serum proteins which strongly inhibited lipofection at low charge ratios but not at higher charge ratios. Furthermore, preincubation of serum with positively charged polylysine, which neutralized negatively charged serum proteins, eliminated the inhibitory effect of serum on lipofection. In summary, inactivation of cationic liposome by serum is due to negatively charged serum proteins and it can be overcome by increasing charge ratio of cationic liposome-DNA lipoplexes or by neutralizing the serum with polylysine.

Serum Is Not Necessary for Prior Pharmacological Activation of AMPK to Increase Insulin Sensitivity of Mouse Skeletal Muscle

Full Text Available Exercise, contraction, and pharmacological activation of AMP-activated protein kinase (AMPK by 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR have all been shown to increase muscle insulin sensitivity for glucose uptake. Intriguingly, improvements in insulin sensitivity following contraction of isolated rat and mouse skeletal muscle and prior AICAR stimulation of isolated rat skeletal muscle seem to depend on an unknown factor present in serum. One study recently questioned this requirement of a serum factor by showing serum-independency with muscle from old rats. Whether a serum factor is necessary for prior AICAR stimulation to increase insulin sensitivity of mouse skeletal muscle is not known. Therefore, we investigated the necessity of serum for this effect of AICAR in mouse skeletal muscle. We found that the ability of prior AICAR stimulation to improve insulin sensitivity of mouse skeletal muscle did not depend on the presence of serum during AICAR stimulation. Although prior AICAR stimulation did not enhance proximal insulin signaling, insulin-stimulated phosphorylation of Tre-2/BUB2/CDC16- domain family member 4 (TBC1D4 Ser711 was greater in prior AICAR-stimulated muscle compared to all other groups. These results imply that the presence of a serum factor is not necessary for prior AMPK activation by AICAR to enhance insulin sensitivity of mouse skeletal muscle.

Full Text Available BACKGROUND Type 2 Diabetes Mellitus (T2DM is an endocrine disorder and a heterogeneous group of syndromes characterised by an elevation of fasting blood glucose that is caused by a relative or absolute deficiency in insulin. Serum vitamin B12 levels have been reported to be inversely associated with the dose and duration of metformin use. Vitamin B12 deficiency is a treatable condition. However, there is insufficient data regarding prevalence of vitamin B12 deficiency in the South Indian population. Hence, the study was undertaken to evaluate serum vitamin B12 levels in T2DM on metformin therapy. MATERIALS AND METHODS A total of 100 T2DM patients attending Outpatient Department (OPD or admitted under Department of General Medicine of KIMS, Hubli, during the time period of 2 years were taken for study considering the inclusion and exclusion criteria. Qualifying patients underwent detailed history, clinical examination, routine investigation and vitamin B12 estimation. RESULTS Majority were in the age group of 45-59 years making 42% of the total. The age group in most patients having vitamin B12 deficiency was >60 years. Males had more vitamin B12 deficiency forming 54.5%. Vitamin B12 deficiency was more in hypertensive group accounting for 71.4%, which was statistically significant. Most of the vitamin B12 deficiency patients had diabetes duration >10 years. Most of the vitamin B12 deficient patients were taking metformin therapy for longer years (≥10 years and in higher dose (>2 g/day. Most of the vitamin B12 deficient diabetes patients were overweight forming 52.5% of the total. CONCLUSION Longer duration of diabetes increases the risk of developing vitamin B12 deficiency on metformin therapy. The higher dose of metformin intake had inverse relation with vitamin B12 levels. Longer duration of metformin intake causes vitamin B12 deficiency and hence should be screened for vitamin B12 deficiency and can be supplemented with vitamin B12.

In patients with acromegaly serum IGF-I is increasingly used as a marker of disease activity. As a result, the relationship between serum GH and IGF-I is of profound interest. Healthy females secrete three times more GH than males but have broadly similar serum IGF-I levels, and women with GH deficiency require 30-50% more exogenous GH to maintain the same serum IGF-I as GH-deficient men. In a selected cohort of patients with active acromegaly, studied off medical therapy using a single fasting serum GH and IGF-I measurement, we have reported previously that, for a given GH level, women have significantly lower circulating IGF-I. To evaluate the influence of age and gender on the relationship between serum GH and IGF-I in an unselected cohort of patients with acromegaly independent of disease control and medical therapy. Sixty (34 male) unselected patients with acromegaly (median age 51 years (range 24-81 years) attending a colonoscopy screening programme were studied. Forty-five had previously received pituitary radiotherapy. Patients had varying degrees of disease control and received medical therapy where appropriate. Mean serum GH was calculated from an eight-point day profile (n = 45) and values obtained during a 75-g oral glucose tolerance test (n = 15). Serum IGF-I, IGFBP-3 and acid-labile subunit were measured and the dependency of these factors on covariates such as log10 mean serum GH, sex, age and prior radiotherapy was assessed using regression techniques. The median calculated GH value was 4.7 mU/l (range 1-104). A significant linear association was observed between serum IGF-I and log10 mean serum GH for the cohort (R = 0.5, P fall by 0.37 nmol/l per year (P = 0.04, 95% CI 0.015-0.72). In keeping with previous observations of relative GH resistance in normal and GH-deficient females we have observed lower serum IGF-I levels for equivalent mean serum GH levels in females patients with acromegaly. This gender-dependent difference is independent of

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.

We report on plasmonic photothermal therapy of rats with inoculated cholangiocarcinoma through the intratumoral injection of PEG-coated gold nanorods followed by CW laser light irradiation. The length and diameter of gold nanorods were 41+/-8 nm and 10+/-2 nm, respectively; the particle mass-volume concentration was 400 μg/mL, which corresponds to the optical density of 20 at the wavelength 808 nm. The tumor-bearing rats were randomly divided into three groups: (1) without any treatment (control); (2) with only laser irradiation of tumor; (3) with intratumoral administration of gold nanorods and laser irradiation of tumors. An hour before laser irradiation, the animals were injected intratumorally with gold nanorod solutions in the amount of 30% of the tumor volume. The infrared 808-nm laser with power density of 2.3 W/cm2 was used for plasmonic photothermal therapy (PTT). The withdraw of animals from the experiment was performed 24 h after laser exposure. The content of lipid peroxidation products and molecular markers of inflammation (TNF-α, IGF-1, VEGF-C) was determined by ELISA test in serum of rats. The standard histological techniques with hematoxylin and eosin staining were used for morphological examination of tumor tissues. It was revealed that the significant necrotic changes were noted in tumor tissue after plasmonic photothermal therapy, which were accompanied by formation of inflammatory reaction with release of proinflammatory cytokines and lipid peroxidation products into the bloodstream

Antithyroid drugs are generally selected as the first-line treatment for Graves' Disease (GD); however, the existence of patients showing resistance or severe side effects to these drugs is an important issue to be solved. The (pro)renin receptor [(P)RR] is a multi-functional protein that activates the tissue renin-angiotensin system and is an essential constituent of vacuolar H+-ATPase, necessary for the autophagy-lysosome pathway. (P)RR is cleaved to soluble (s)(P)RR, which reflects the status of (P)RR expression. In this retrospective study, we aimed to investigate whether serum s(P)RR concentration can be used as a biomarker to predict the outcome of antithyroid drug treatment in GD patients. Serum s(P)RR levels were measured in 54 untreated GD patients and 47 control participants. Effects of medical treatment with antithyroid drugs on these levels were investigated in GD patients. Serum s(P)RR levels were significantly higher in patients with Graves' disease than in control subjects (PGraves' disease. High serum s(P)RR levels were associated with resistance to antithyroid drug treatment, suggesting that serum s(P)RR concentration can be used as a useful biomarker to predict the outcome of antithyroid drug treatment in these patients. Patients with Graves' disease with low body mass index showed higher levels of serum soluble (pro)renin receptor levels than those with high body mass index. In addition, in patients with Graves' disease, serum triglyceride levels were negatively correlated with serum soluble (pro)renin receptor levels. All these data indicated an association between low nutrient condition due to hyperthyroidism and increased (pro)renin receptor expression in these patients, suggesting that (pro)renin receptor expression could be increased in the process of stimulating intracellular energy production via activating autophagy function to compensate energy loss.

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

Full Text Available Abstract Background Liver fibrosis ranks as the second cause of death in México's productive-age population. This pathology is characterized by acummulation of fibrillar proteins in hepatic parenchyma causing synthetic and metabolic disfunction. Remotion of excessive fibrous proteins might result in benefit for subjects increasing survival index. The goal of this work was to find whether the already known therapeutical effect of human urokinase Plasminogen Activator and human Matrix Metalloprotease 8 extends survival index in cirrhotic animals. Methods Wistar rats (80 g underwent chronic intoxication with CCl4: mineral oil for 8 weeks. Cirrhotic animals were injected with a combined dose of Ad-delta-huPA plus Ad-MMP8 (3 × 1011 and 1.5 × 1011 vp/Kg, respectively or with Ad-beta-Gal (4.5 × 1011 and were killed after 2, 4, 6, 8 and 10 days. Then, liver and serum were collected. An additional set of cirrhotic animals injected with combined gene therapy was also monitored for their probability of survival. Results Only the cirrhotic animals treated with therapeutical genes (Ad-delta-huPA+Ad-MMP-8 showed improvement in liver fibrosis. These results correlated with hydroxyproline determinations. A significant decrement in alpha-SMA and TGF-beta1 gene expression was also observed. Cirrhotic rats treated with Ad-delta-huPA plus Ad-MMP8 had a higher probability of survival at 60 days with respect to Ad-beta-Gal-injected animals. Conclusion A single administration of Ad-delta-huPA plus Ad-MMP-8 is efficient to induce fibrosis regression and increase survival in experimental liver fibrosis.

Interferon beta (INFbeta) may induce the expression of several proteins, including neopterin, considered a biological marker of INFbeta activity. The aim of this study was to determine the serum neopterin concentration at the beginning of, and during, IFNbeta-1a therapy in relapsing-remitting multiple sclerosis (r-r MS) patients, and to look for a possible correlation between protein synthesis and the clinical course of the disease. Thirteen r-r MS patients were treated with INFbeta-1a (i.m. 6 MIU/week) for 2 years. Blood samples for neopterin determinations were taken daily over a period of 1 week at the end of each 6 months of therapy, and tested for neutralizing antibodies (NABs). Neopterin levels peaked 24-48 h post-injection and returned to baseline after 120 h. After 1 year of therapy, four patients dropped out of the study because of progression of the disease: in these subjects a significant decrement of neopterin was observed. Neopterin baseline values were not found to decrease over the 2 years of therapy, and neopterin may be considered to be a useful marker of responsiveness to IFNbeta.

To investigate changes of serum total oxidation status (TOS) and total antioxidant status (TAS) and their association with apolipoprotein (a) [Apo(a)] in patients with polycystic ovary syndrome (PCOS) combined with infertility. Ninety patients with PCOS and infertility were selected as the study group, including 45 patients treated with antioxidants combined with Diane-35(group A) and 45 with Diane-35 therapy only (group B), with 45 healthy volunteers with normal menstruation and normal dual phase basic body temperatures as the control group. Serum TOS of the participants was determined by dual xylenol orange method, and serum TAS was determined with ABTS method; plasma Apo(a) level was determined by dual wavelength immune transmission turbidity method. Before treatment, serum TOS, OSI, and Apo(a) levels were significantly higher and TAS level was significantly lower in the study group than in the control group (P<0.05). Serum TOS, OSI, and Apo (a) were significantly lowered and TAS was significantly increased in group A after the therapy as compared with the levels before therapy and the levels in group B. The rate of natural recovery of menstruation was significantly higher and the incidence of cardiovascular disease was significantly lower in group A than in group B (P<0.05). Pearson correlation analysis showed that serum TOS and OSI were positively correlated with plasma Apo(a) (r=0.524 and 0.531, P<0.05), and serum TAS was negatively correlated with plasma Apo(a) (r=-0.519, P<0.05). Antioxidant therapy can lower TOS, OSI and Apo(a) levels and increase TAS level to lessen oxidative stress, improve the prognosis, and reduce the risks of cardiovascular disease in patients with PCOS and infertility.

Ghrelin has been proved to inhibit inflammation and promote cartilage growth. So far, its role in patients with primary knee osteoarthritis has not been investigated. The current study was performed to explore the serum and synovial ghrelin levels as well as the relationship between ghrelin levels and disease severity in primary knee OA patients. 52 primary knee OA patients were recruited in the study. 52 sex and age-matched patients visiting our hospital for regular body check were selected as controls. The serum and synovial fluid ghrelin levels were examined by enzyme linked immunosorbent assay (ELISA) before treatment, one week and four weeks after laser therapy, respectively. The inflammation markers IL-6 and TNF-α were also investigated. The radiographic progression was assessed by Kellgren-Lawrence (K-L) grade scale and the symptomatic severity was evaluated by visual analog scale (VAS), Lequesne index and Lysholm scores. The Receiver Operating Characteristic (ROC) analysis curve was conducted to test the diagnostic value of ghrelin, IL-6 and TNF-α for radiographic progression. No significant difference of serum ghrelin levels was found between knee OA patients and healthy controls. Synovial fluid ghrelin concentrations were significantly negatively correlated with K-L grading (r=-0.591, Pghrelin levels were also related to clinical severity determined by Lequesne index (r=-0.308, P=0.025),VAS scores (r=-0.591, Pghrelin levels were also negatively associated with TNF-α (r=-0.424, P=0.002) and IL-6 concentrations (r=-0.428, P=0.002). ROC curve analysis demonstrated that ghrelin exhibited more diagnostic value than IL-6 and TNF-α for assessing radiographic progression in medium-late stage. Decreased synovial fluid ghrelin levels are related to disease severity in patients with primary osteoarthritis and are increased following laser therapy. Local application of ghrelin may serve as an adjunctive therapy for knee OA. Copyright © 2017. Published by

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

Full Text Available Cystatin C (CSTC is an inhibitor of cysteine proteinases and could play a protective and regulatory role under inflammatory conditions. The present study was designed to assess the concentration of CSTC in gingival crevicular fluid (GCF and serum, to find out their association if any, in periodontal health and disease. 30 subjects were selected divided into 3 groups consisting of 10 subjects in each group based on clinical parameters: periodontally healthy group, gingivitis group and chronic periodontitis group, while, chronic periodontitis group after 8 weeks of the treatment (scaling and root planing constituted after periodontal therapy group. GCF and serum samples were collected from all subjects to estimate the levels of CSTC by ELISA. The mean CSTC concentration in GCF and serum was observed to be the highest in periodontitis group and lowest in periodontally healthy group with intermediate concentration in gingivitis group and after periodontal therapy group. CSTC concentration in GCF and serum increased proportionally with the severity of periodontal disease (from health to periodontitis group and decreased after treatment. This suggests that CSTC increases with disease progression to prevent further periodontal degeneration and decreases after treatment due to bone metabolic homeostasis. Further, longitudinal prospective studies involving larger population are needed to confirm the findings of present study and to better understand the role of CSTC in the pathogenesis of periodontal diseases.

Full Text Available Visfatin is a pleiotropic mediator which acts as growth factor, cytokine, enzyme involved in energy including nicotinamide adenine dinucleotide metabolism and has been recently demonstrated to exert several pro-inflammatory functions. The purpose of this study is to evaluate the Visfatin concentration in gingival crevicular fluid (GCF and serum in patients with chronic periodontitis, and to evaluate the effect of non-surgical periodontal therapy on the GCF and serum visfatin concentration. 30 subjects (age range: 25 to 52 years were selected and divided into two groups based on the gingival index, probing depth, periodontal attachment level, and radiologic parameters (bone loss: group 1 (15 subjects with healthy periodontium, group 2 (15 subjects with chronic periodontitis, while, Group 2 patients after 8 weeks of the treatment (scaling and root planning, SRP constituted group 3. GCF samples (by microcapillary pipettes and serum samples (by venipuncture were collected to estimate the levels of Visfatin using enzyme linked immunosorbent assay kit. The mean Visfatin concentration in GCF and serum was observed to be the highest in group 2 and lowest in group 1. While concentration in group 3 was similar to group 1. The concentration of Visfatin in GCF and serum decreased after SRP. The Visfatin concentration in GCF and serum found to be highest in chronic periodontitis group and decreases after treatment. Hence Visfatin values can be considered as an “inflammatory marker” can be explored in future as a potential therapeutic target in the treatment of periodontal disease.

In order to assess value of serum prostate-specific antigen (PSA) levels in the monitoring of patients with localized prostatic carcinoma undergoing radical radiation therapy, 146 previously untreated patients were studied. To the prostate 60-70 Gy were administered over 8-9 weeks. Median follow-up was 28 every 3 months during 1st year and every 6 months after. Serum PSA levels were measured prior to radiotherapy. Pre-treatment PSA values exceeded 10 ng/ml in 62%. Initial PSA values were correlated with tumor size and Gleason score. PSA levels decreased 6 months after completion of radiation therapy, compared to initial value in 88.3%. It had fallen to 10 ng/ml or less in 59% with initial abnormal PSA levels. Patients whose initial PSA exceeded 50 ng/ml attained levels of 10 ng/ml or less in only 19%. Only 3/55 with both initial and 6-month PSA values ≤ 10 ng/ml developed metastases. Of 91 patients with initial PSA values over 10 ng/ml 54 had a 6-month PSA level of 10 ng/ml or less, and only 4/54 relapsed. By contrast, 13/37 patients with a 6-month PSA level persistently above 10 ng/ml relapsed. The 3-year relapse-free survival is 85.1% for 6-month PSA level ≤ 10 ng/ml, and 50.2% for patients with persistently elevated PSA values. This difference is highly significant (p 10 ng/ml and relative difference between an initial and a 6-month PSA value of less than 50%, developed metastases. By contrast, when relative difference was ≥50%, only 6/69 belonging to this group had local recurrence or developed metastases. The 3-year relapse-free survival rate was significantly superior in latter group (76.9 versus 30.2%, p<0.0001). It is concluded that a PSA value in excess of 10 mg/nl 6 months after radiation therapy or a relative difference between an initial and a 6- month PSA value of less than 50% have a poor prognostic significance and are discriminant criteria to identify a subset of patients with a high risk of relapse who may benefit from early hormonal therapy

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

Blood concentrations of triglycerides are influenced by genetic factors as well as a number of environmental factors, including adiposity and glucose homeostasis. The aim was to investigate the association between a serum triglyceride weighted genetic risk score (wGRS) and changes in fasting serum...... triglyceride level over 5 years and to test whether the effect of the wGRS was modified by 5 year changes of adiposity, insulin resistance, and lifestyle factors. A total of 3,474 nondiabetic individuals from the Danish Inter99 cohort participated in both the baseline and 5 year follow-up physical examinations...... and had information on the wGRS comprising 39 genetic variants. In a linear regression model adjusted for age, sex, and baseline serum triglyceride, the wGRS was associated with increased serum triglyceride levels over 5 years [per allele effect = 1.3% (1.0-1.6%); P = 1.0 × 10(-17)].

Serum Renalase Levels Correlate with Disease Activity in Lupus Nephritis.

Directory of Open Access Journals (Sweden)

Chaojun Qi

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

n-3 Tetracosapentaenoic acid (24:5n-3, TPAn-3) and tetracosahexaenoic acid (24:6n-3, THA) are believed to be important intermediates to docosahexaenoic acid (DHA, 22:6n-3) synthesis. The purpose of this study is to report for the first time serum concentrations of TPAn-3 and THA and their response to changing dietary α-linolenic acid (18:3n-3, ALA) and DHA. The responses will then be used in an attempt to predict the location of these fatty acids in relation to DHA in the biosynthetic pathway. Male Long Evans rats (n = 6 per group) were fed either a low (0.1% of total fatty acids), medium (3%) or high (10%) ALA diet with no added DHA, or a low (0%), medium (0.2%) or high (2%) DHA diet with a background of 2% ALA for 8 weeks post-weaning. Serum n-3 and n-6 polyunsaturated fatty acid (PUFA) concentrations (nmol/mL ± SEM) were determined by gas chromatography-mass spectrometry. Serum THA increases from low (0.3 ± 0.1) to medium (5.8 ± 0.7) but not from medium to high (4.6 ± 0.9) dietary ALA, while serum TPAn-3 increases with increasing dietary ALA from 0.09 ± 0.04 to 0.70 ± 0.09 to 1.23 ± 0.14 nmol/mL. Following DHA feeding, neither TPAn-3 or THA change across all dietary DHA intake levels. Serum TPAn-3 demonstrates a similar response to dietary DHA. In conclusion, this is the first study to demonstrate that increases in dietary ALA but not DHA increase serum TPAn-3 and THA in rats, suggesting that both fatty acids are precursors to DHA in the biosynthetic pathway.

Previous studies have found markedly elevated serum concentrations of proinflammatory cytokines in patients with Graves' disease (GD). We investigated the role of macrophage colony-stimulating factor (M-CSF) in GD. We assayed concentrations of M-CSF in sera from 32 patients with GD (25 untreated; 7 receiving thiamazole therapy). We also studied 32 age-matched healthy subjects as controls. Relationships between serum M-CSF and both thyroid state and serum lipids were examined. Moreover, to examine the effect of thyroid hormone alone on serum M-CSF, T3 was administered orally to normal subjects. Serum concentrations of M-CSF in GD patients who were hyperthyroid were significantly increased compared with GD patients who were euthyroid (P oral T3 administered to 15 volunteers for 7 days produced significant increases in serum levels of M-CSF (P production of M-CSF in patients with GD.

Is DTPA a good competing chelating agent for Th(IV) in human serum and suitable in targeted alpha therapy?

The interaction between thorium and human serum components was studied using difference ultraviolet spectroscopy (DUS), ultrafiltration and high-pressure-anion exchange chromatography (HPAEC) with external inductively conducted plasma mass spectrometry (ICP-MS) analysis. Experimental data are compared with modelling results based on the law of mass action. Human serum transferrin (HSTF) interacts strongly with Th(IV), forming a ternary complex including two synergistic carbonate anions. This complex governs Th(IV) speciation under blood serum conditions. Considering the generally used Langmuir-type model, values of 10(33.5) and 10(32.5) were obtained for strong and weak sites, respectively. We showed that trace amounts of diethylene triamine pentaacetic acid (DTPA) cannot complex Th(IV) in the blood serum at equilibrium. Unexpectedly this effect is not related to the competition with HSTF but is due to the strong competition with major divalent metal ions for DTPA. However, Th-DTPA complex was shown to be stable for a few hours when it is formed before addition in the biological medium; this is related to the high kinetic stability of the complex. This makes DTPA a potential chelating agent for synthesis of (226)Th-labelled biomolecules for application in targeted alpha therapy. Copyright © 2011 Elsevier Inc. All rights reserved.

Antithyroid drugs are generally selected as the first-line treatment for Graves’ Disease (GD); however, the existence of patients showing resistance or severe side effects to these drugs is an important issue to be solved. The (pro)renin receptor [(P)RR] is a multi-functional protein that activates the tissue renin-angiotensin system and is an essential constituent of vacuolar H+-ATPase, necessary for the autophagy-lysosome pathway. (P)RR is cleaved to soluble (s)(P)RR, which reflects the status of (P)RR expression. In this retrospective study, we aimed to investigate whether serum s(P)RR concentration can be used as a biomarker to predict the outcome of antithyroid drug treatment in GD patients. Serum s(P)RR levels were measured in 54 untreated GD patients and 47 control participants. Effects of medical treatment with antithyroid drugs on these levels were investigated in GD patients. Serum s(P)RR levels were significantly higher in patients with Graves’ disease than in control subjects (Pantithyroid drug treatment, suggesting that serum s(P)RR concentration can be used as a useful biomarker to predict the outcome of antithyroid drug treatment in these patients. Patients with Graves’ disease with low body mass index showed higher levels of serum soluble (pro)renin receptor levels than those with high body mass index. In addition, in patients with Graves’ disease, serum triglyceride levels were negatively correlated with serum soluble (pro)renin receptor levels. All these data indicated an association between low nutrient condition due to hyperthyroidism and increased (pro)renin receptor expression in these patients, suggesting that (pro)renin receptor expression could be increased in the process of stimulating intracellular energy production via activating autophagy function to compensate energy loss.

Increased serum triglycerides and reduced HDL cholesterol in male rats after intake of ammonium chloride for 3 weeks

Science.gov (United States)

2013-01-01

Background Previous data suggested that intake of sodas and other acid beverages might be associated with increased levels of serum triglycerides, lowered HDL cholesterol, and increased formation of mono unsaturated fatty acids, which are the preferred ones for triglyceride synthesis. The present work is an extension of these studies. Methods Thirty male rats were divided into 3 groups. All groups were given the same food, but various beverages: water (W), ammonium chloride, 200 mmol/L (AC), or sodium bicarbonate, 200 mmol/L (SB). Serum triglycerides, HDL cholesterol, and the fatty acid distribution in total serum lipids were determined. Delta9-desaturase in serum lipids was estimated by the ratio of palmitoleic to palmitic acid, and by the oleic/stearic acid ratio. Correlation and ANOVA were used to study associations and group differences. Results After 3 weeks, the AC group had higher triglyceride concentration and higher Delta9 desaturase indexes, but lower serum HDL and body weight as compared with the SB and W groups. In each of the groups, the oleic acid/stearic acid ratio correlated positively with serum triglycerides; in the pooled group the correlation coefficient was r = 0.963, ptriglycerides, and lowered HDL cholesterol concentration, thereby possibly contributing to explain the increased triglyceride concentration previously observed in subjects with a frequent intake of acid beverages, such as sodas containing carbonic acid, citric acid, and phosphoric acid.

Biologics show great efficacy in treating psoriasis, a chronic inflammatory skin disease. The high cost and side-effects of biologics, dose-reduction, elongation of administration interval and suspension are possible options. However, there has been no reliable biomarker we can use when we consider these moderations in therapy. This study was conducted to test the possibility of using serum thymus and activation-regulated chemokine (TARC) level as an indicator for step down of biologic therapy. Serum TARC level was measured in 70 psoriatic patients at Asahikawa Medical University, and a correlation of TARC and severity of skin lesions was analyzed. Referring to serum TARC level, psoriatic patients can be divided into two groups. One is a population in which serum TARC level is positively correlated with severity of skin lesions, and the other is a population with low psoriatic severity and high TARC level. Serum TARC level was higher in the group that achieved PASI-clear with biologics than in the group which did not achieve PASI-clear. Among biologics, the group treated with secukinumab, an anti-interleukin (IL)-17A agent, showed significantly higher TARC level compared with the group treated with anti-tumor necrosis factor agents. In certain populations achieving PASI-clear, serum TARC level may be a potent marker reflecting better response to IL-17A inhibitors, and in this case step down of treatment for psoriasis is possible. © 2018 Japanese Dermatological Association.

Hydrocortisone therapy is based on a dosing regimen derived from estimates of cortisol secretion, but little is known of how the dose should be distributed throughout the 24 h. We have used deconvolution analysis of 24-h serum cortisol profiles to determine 24-h cortisol secretion and distribution to inform hydrocortisone dosing schedules in young children and older adults. Twenty four hour serum cortisol profiles from 80 adults (41 men, aged 60-74 years) and 29 children (24 boys, aged 5-9 years) were subject to deconvolution analysis using an 80-min half-life to ascertain total cortisol secretion and distribution throughout the 24-h period. Mean daily cortisol secretion was similar between adults (6.3 mg/m(2) body surface area/day, range 5.1-9.3) and children (8.0 mg/m(2) body surface area/day, range 5.3-12.0). Peak serum cortisol concentration was higher in children compared with adults, whereas nadir serum cortisol concentrations were similar. Timing of the peak serum cortisol concentration was similar (07.05-07.25), whereas that of the nadir concentration occurred later in adults (midnight) compared with children (22.48) (P = 0.003). Children had the highest percentage of cortisol secretion between 06.00 and 12.00 (38.4%), whereas in adults this took place between midnight and 06.00 (45.2%). These observations suggest that the daily hydrocortisone replacement dose should be equivalent on average to 6.3 mg/m(2) body surface area/day in adults and 8.0 mg/m(2) body surface area/day in children. Differences in distribution of the total daily dose between older adults and young children need to be taken into account when using a three or four times per day dosing regimen. © 2012 Blackwell Publishing Ltd.

The concentration of serum iron, the plasma cholesterol level, the hip-waist ratio and body mass index of 70 patients with evidence of CHD seen at a Cardiology Unit of a Specialist Hospital in Ibadan and 70 healthy subjects selected randomly were determined. Subjects were grouped into four age categories and three socioeconomic classes (high, middle and low). The age of the subjects ranged from 31-70 years with the mean of 53.6+-11.0 years and 50.1+-10.5 years for patients and controls respectively. The mean serum iron and plasma cholesterol levels were significantly higher among patients than controls irrespective of age and sex (p<0.05). No correlation was found between serum iron and the variables; plasma cholesterol level, age, body mass index (BMI) and hip-waist ratio. Significantly higher serum iron levels found in patients with evidence of CHD appears to support the hypothesis that there is a potential association between iron status and CHD. (author)

BACKGROUND/AIMS: YKL-40, a mammalian member of the chitinase family, is a lectin that binds heparin and chitin. The function of YKL-40 is unknown, but it may function in tissue remodelling. The aims of this study were to assess the level of circulating YKL-40 in patients with various kinds...... with the blood sample. RESULTS: The median serum YKL-40 was highest in patients with alcoholic cirrhosis (532 microg/l), in particular in patients with additional alcoholic hepatitis (740 microg/l). Patients with alcoholic cirrhosis, post-hepatitic cirrhosis (425 microg/l) and non-cirrhotic fibrosis (330 microg/l......) had significantly higher serum YKL-40 than normal subjects (102 microg/l), patients with fatty liver (195 microg/l) or patients with viral hepatitis without fibrosis (174 microg/l). Serum YKL-40 was significantly (p

Men who have symptoms associated with persistently low serum total testosterone level should be assessed for testosterone replacement therapy. Acute and chronic illnesses are associated with low serum testosterone and these should be recognized and treated. Once the diagnosis of male hypogonadism is made, the benefits of testosterone treatment usually outweigh the risks. Without contraindications, the patient should be offered testosterone replacement therapy. The options of testosterone delivery systems (injections, transdermal patches/gels, buccal tablets, capsules and implants) have increased in the last decade. Testosterone improves symptoms and signs of hypogonadism such as sexual function and energy, increases bone density and lean mass and decreases visceral adiposity. In men who desire fertility and who have secondary hypogonadism, testosterone can be withdrawn and the patients can be placed on gonadotropins. New modified designer androgens and selective androgen receptor modulators have been in preclinical and clinical trials for some time. None of these have been assessed for the treatment of male hypogonadism. Despite the lack of prospective long-term data from randomized, controlled clinical trials of testosterone treatment on prostate health and cardiovascular disease risk, the available evidence suggests that testosterone therapy should be offered to symptomatic hypogonadal men.

To explore the clinical efficacy and effect mechanism on chronic urticaria treated with moving cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints. One hundred and four patients of chronic urticaria were randomized into a comprehensive therapy group and a medication group, 52 cases in each one. In the comprehensive therapy group, the moving cupping therapy along the governor vessel and bladder meridian of foot-taiyang was applied combined with autohemotherapy with acupaint injection for desensitization at acupoints. The self-venous blood was injected at bilateral Quchi (LI 11) and Zusanli (ST 36), 1 mL at each acupoint, once every 3 days. In the medication group, cetirizine tablets, 10 mg were prescribed for oral administration, once every day, and the compound dexamethasone acetate cream was used externally, once to twice a day. The clinical efficacy: was observed in 30 days of treatment in the two groups. The changes of serum interleukin 4 (IL-4) and immunoglobulin E (Ig E) before and after treatment were observed. The recurrence rate was compared between the two groups in 3 months after treatment. The cured and markedly effective rate was 90.4% (47/52) in the comprehensive therapy group, which was higher obviously than 78.8% (41/52, P therapy group was much more significant than that in the medicine group (both P therapy group in the 3-month follow-up after treatment, and apparently lower than 51.2% (21/41, P cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints achieves the better efficacy on chronic urticaria compared with the routine western medicine treatment and the recurrence rate is low. The effect mechanism is possibly related to the down-regulation of serum IL-4 and IgE in the patients.

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

Diabetes is associated with an increased risk for vascular disease and periodontitis. The aim of this study was to assess the effects of periodontal treatment in diabetes with respect to alterations in the pro-inflammatory potential of peripheral blood mononuclear cells. Ten patients with diabetes and moderate to severe periodontitis received full-mouth subgingival debridement. Blood samples for serum/plasma and mononuclear cell isolation were collected prior to and 4 wk after therapy. Mononuclear cells were analyzed by flow cytometry and stimulated with lipopolysaccharide or ionomycin/phorbol ester to determine the pro-inflammatory capacity of macrophages and lymphocytes, respectively. Following periodontal treatment, all patients demonstrated a significant improvement in clinical periodontal status (p C-reactive protein significantly decreased by 37% (p periodontal therapy and a potential impact on atherosclerosis-related complications in diabetic individuals.

Levels of antibodies against the hepatitis B virus (HBV) core protein (anti-HBc) have been associated with response to nucleos(t)ide analogue and (peg)interferon therapy in patients with chronic HBV infection. We performed a prospective study to determine whether the total serum level of anti-HBc level (immunoglobulins M and G) is associated with clinical relapse after discontinuation of nucleos(t)ide analogue-based therapy. We collected data from patients with chronic HBV infection who discontinued nucleos(t)ide analogue therapy according to pre-specified stopping criteria, recruited from November 2012 through July 2016 at an academic hospital in Guangzhou, China. Patients were followed through February 2017. We performed comprehensive biochemical and virologic tests at every visit, and anti-HBc was quantified for 2 years after treatment cessation (at baseline and weeks 4, 8, 12, 24, 48, and 96). The primary endpoint was clinical relapse, defined as level of HBV DNA >2000 IU/mL and level of alanine aminotransferase more than 2-fold the upper limit of normal-these were also the criteria for retreatment. We followed 100 patients (71% positive for HB e antigen [HBeAg] at the start of nucleos(t)ide analogue therapy, 43% treated with entecavir or tenofovir) for a median of 2.5 years after stopping therapy. Clinical relapse occurred in 39 patients (in 46% of patients at year 4 after discontinuation). High level of anti-HBc at the end of treatment (hazard ratio [HR], 0.31 per log IU/mL; P=.002) and low level of HB surface antigen (HBsAg) at the end of treatment (HR, 1.71 per log IU/mL; P=.032) were associated with a reduced risk of clinical relapse after adjusting for age, start of nucleos(t)ide analogue therapy HBeAg-status, and consolidation therapy duration. At year 4, 21% of patients with anti-HBc levels at the end of treatment ≥1000 IU/mL developed a clinical relapse compared to 85% of patients with levels level at the end of treatment ≤100 IU/mL was associated

High mobility group box 1 (HMGB1) is a highly conserved, ubiquitous protein that functions as an activator for inducing the immune response and can be released from neurons after glutamate excitotoxicity. The objective of the present study was to measure serum levels of HMGB1 in patients with autistic disorder and to study their relationship with clinical characteristics. We enrolled 22 adult patients with autistic disorder (mean age: 28.1+/-7.7 years) and 28 age- and gender-matched healthy controls (mean age: 28.7+/-8.1 years). Serum levels of HMGB1 were measured by enzyme-linked immunosorbent assay (ELISA). Compared with healthy subjects, serum levels of HMGB1 were significantly higher in patients with autistic disorder (10.8+/-2.6 ng/mL versus 5.6+/-2.5 ng/mL, respectively, Pautistic disorder. Increased HMGB1 may be a biological correlate of the impaired reciprocal social interactions in this neurodevelopmental disorder. Copyright 2010 Elsevier Inc. All rights reserved.

The combination of chemotherapy with the vascular endothelial growth factor (VEGF) antibody bevacizumab is a standard of care in advanced colorectal cancer (CRC). However, biomarkers predicting outcome of bevacizumab-containing treatment are lacking. As angiopoietin-2 (Ang-2) is a key regulator of vascular remodelling in concert with VEGF, we investigated its role as a biomarker in metastatic CRC. Serum Ang-2 levels were measured in 33 healthy volunteers and 90 patients with CRC. Of these, 34 had metastatic disease and received bevacizumab-containing therapy. To determine the tissue of origin of Ang-2, quantitative real-time PCR was performed on microdissected cryosections of human CRC and in a murine xenograft model of CRC using species-specific amplification. Ang-2 originated from the stromal compartment of CRC tissues. Serum Ang-2 levels were significantly elevated in patients with metastatic CRC compared with healthy controls. Amongst patients receiving bevacizumab-containing treatment, low pre-therapeutic serum Ang-2 levels were associated with a significant better response rate (82 vs 31%; Panti-angiogenic treatment.

A radioimmunoassay for serum ursodeoxycholic conjugates using an iodine-125 ligand has been developed. The bile acid was present in normal fasting serum (0.19 +- SD 0.19 μmol/l, n=24) and 2-hour post-prandial serum (0.8 +- SD 0.8 μmol/l, n=16). Gallstone patients undergoing oral ursodeoxycholic acid therapy had significantly higher post-prandial serum levels (21.5 +- SD 14.0 μmol/l, n=15) by radioimmunoassay. Gas liquid chromatography analysis indicated that in normal serum ursodeoxycholic acid was totally conjugated, whereas sera from gallstone patients contained a proportion as the free bile acid (10.2 +- SD 8.1 μmol/l, n=15). Following an oral dose of ursodeoxycholic acid, both unconjugated and conjugated forms of the bile acid appeared in the serum of healthy individuals. (Auth.)

Increase in tiagabine serum concentration with coadministration of gemfibrozil.

To report a case of possible acute tiagabine toxicity secondary to administration of gemfibrozil. A 39-year-old male was taking tiagabine 16 mg orally 3 times per day and carbamazepine 500 mg orally twice per day for complex partial seizures secondary to mesial temporal sclerosis. He was found to have type IV hypertriglyceridemia and was prescribed gemfibrozil. Because he reported severe confusion and altered consciousness shortly after a single 600-mg dose of gemfibrozil, he was admitted for controlled challenge with that drug. A single 300-mg dose of gemfibrozil resulted in lightheadedness and led to a 59% and 75% increase in total tiagabine serum concentrations at 2 and 5 hours, respectively, without significant change in baseline carbamazepine concentrations. This is the first report of an interaction between the widely used antihyperlipidemic drug gemfibrozil and tiagabine. Since tiagabine, which was originally developed as an antiepileptic medication, is now being used widely for a variety of other indications such as anxiety and depression, there is an increased risk for clinically significant interactions with gemfibrozil. Increased total and unbound tiagabine concentrations following a single 300-mg dose of gemfibrozil and reproduction of clinical symptoms with gemfibrozil rechallenge suggests the toxicity our patient experienced was due to a pharmacokinetic drug interaction. Use of the Horn Drug Interaction Probability Scale showed a probable interaction between gemfibrozil and tiagabine.

Increased Serum Pepsinogen II Level as a Marker of Pangastritis and Corpus-Predominant Gastritis in Gastric Cancer Prevention.

Serum pepsinogen I and II are considered as indicators of changes in gastric morphology. Important publications from the last decades are reviewed with regard to the serum level of these biomarkers for the diagnosis of normal gastric mucosa, diffuse gastritis and its change to atrophic gastritis and intestinal metaplasia as well as gastric cancer. Due to the low sensitivity of serum biomarkers for diagnosis of gastric cancer, especially at its early stage and the poor prognosis of the tumor at the time of diagnosis, its prevention by eradication of H. pylori remains the mandatory strategy. On the other hand, the severity of regression and non-reversibility of precancerous lesions and intestinal metaplasia in gastric mucosa through eradication of H. pylori make it necessary to diagnose diffuse gastritis at its early stage. Increased serum pepsinogen II compared to normal serum pepsinogen I seems to indicate the presence of diffuse gastritis without precancerous lesions suitable for eradication of H. pylori infection, when it is serologically positive. A diagram illustrates the strategy of this therapeutic measure depending on the age of people and the level of serum biomarkers in areas with high gastric cancer prevalence.

Increased Serum and Urinary Oxytocin Concentrations after Nasal Administration in Beagle Dogs

Andrea Temesi

2017-09-01

Full Text Available In recent years more and more studies have revealed the effect of extraneous oxytocin on the social behavior of dogs. The distribution of administered oxytocin in different physiologically relevant compartments is important because this knowledge forms the basis for the timing of behavior tests after the administration. Most behavioral studies rely on the non-invasive intranasal application of oxytocin. The aim of this study was to determine the time course of intranasal administered oxytocin secretion into blood and urine and also establish a connection between intranasal received oxytocin and urinary cortisol in dogs. In our experiment, four dogs received three puffs, 12 IU intranasal oxytocin treatment, two dogs received three puffs intranasal placebo treatment. Blood and urine samples were collected immediately prior to the administration then regularly during 4 h. After nasal oxytocin application, the serum oxytocin concentration increased, reached a maximum 15 min after the treatment and then rapidly returned to baseline levels 45 min later. The peak urinary oxytocin concentration occurred between 45 and 60 min after administration and returned to baseline levels slowly. We found considerable differences among individuals in the secretion of oxytocin in both the serum and the urinary oxytocin concentration measurements. Our results confirm that intranasally administered oxytocin passes into the blood stream. The time course of intranasally administered oxytocin secretion is similar to the time course of intravenously administered oxytocin secretion, and the peak values are also similar in both the serum and the urinary oxytocin concentration measurements, although there are large individual differences.

To determine whether the high prevalence of hepatitis B surface antigen (HBsAg) carriage in our population can explain the previous observation of an association between increased maternal serum ferritin concentration and gestational diabetes in Hong Kong Chinese women. A retrospective study was performed on 767 nonanemic women with singleton pregnancy who had iron status assessed at 28-30 weeks. The result of the routine antenatal HBsAg screening was retrieved from patient records. The HBsAg-positive and -negative groups were compared for maternal characteristics, prevalence of gestational diabetes in the third trimester, prevalence of high serum ferritin and iron concentrations, and transferrin saturation, which is defined as a value in the highest quartile established by the measurements obtained from the HBsAg-negative group. The incidences of oral glucose tolerance test and gestational diabetes were significantly increased in the HBsAg-positive group. The HBsAg-positive women with gestational diabetes had significantly increased prevalence of high serum ferritin compared with the HBsAg-negative women, irrespective of the latter's gestational diabetes status. Multiple logistic regression analysis confirmed the independent association between HBsAg carrier status with gestational diabetes (relative risk 3.51, 95% CI 1.83-6.73) but excluded high ferritin as an independent factor. Our results indicate that maternal HBsAg carriage could explain in part the association between increased serum ferritin concentration with gestational diabetes in Hong Kong Chinese women, and that HBsAg carrier status is an independent risk factor for gestational diabetes.

Methods: Blood samples from healthy controls and 22 patients 15 women (7 aged from 20 to 30 and 8 were > 40 years old and 7 men (5 aged from 20 to 30 and 2 were > 40 years old fulfilling the McDonald Criteria and classified as having Relapsing-Remitting Multiple Sclerosis accordingly with Lublin were collected for oxidative stress markers quantification. Results: Nitric oxide metabolites (nitrates/nitrites, lipid peroxidation products (malondialdehyde plus 4-hidroxialkenals, and glutathione peroxidase activity were significantly increased in serum of subjects with relapsing-remitting multiple sclerosis in comparison with that of healthy controls. These data support the hypothesis that multiple sclerosis is a component closely linked to oxidative stress.

Increased intestinal permeability with subsequent metabolic endotoxemia, i.e., elevated circulating levels of bacterial lipopolysaccharide, LPS, has been introduced as a novel initiator of obesity related metabolic disturbances in non-pregnant individuals. The objective was to investigate the extent to which intestinal permeability, measured by serum zonulin concentration, is related to metabolic endotoxemia and metabolic risk markers in overweight pregnant women. This was a cross-sectional study including 100 pregnant overweight women in early pregnancy. Serum zonulin was analyzed using ELISA, and markers for metabolic endotoxemia (LPS), inflammation (high-sensitive C-reactive protein and glycoprotein acetylation GlyA), glucose metabolism (fasting glucose and insulin), and lipid metabolism were measured. Higher serum zonulin concentration associated positively with LPS (P=0.02), inflammatory markers (Pzonulin quartiles). All the observed associations were confirmed (Pzonulin concentration, i.e., increased intestinal permeability, contributes to metabolic endotoxemia, systemic inflammation, and insulin resistance in overweight pregnant women. By reinforcing intestinal barrier, it may be possible to manipulate maternal metabolism during pregnancy with subsequent health benefits. Copyright © 2017 Elsevier Inc. All rights reserved.

Diagnostic relevance of radioiron-absorption-measurements and immunoradiometric serum-ferritin-assay in the evaluation of iron stores

International Nuclear Information System (INIS)

Heinrich, H.C.

1978-01-01

Negative iron balance and enhanced iron demand respectively causes deficient iron stores (prelatent iron deficiency) with increased iron absorption, later on decrease of serum iron and increase of transferrin (latent Fe deficiency) and at least iron deficient anemia (manifest iron deficiency). In prelatend iron deficiency diagnostic 59 Fe 2+ absorption is increased and the RES cells do not show storage iron cytochemically. In latent iron deficiency in addition serum iron, transferrin iron saturation and serum ferritin is decreased and hypochromic mikrocytic anemia completes the signs of manifest iron deficiency. Besides rare cases of primary hemochromatosis and marked hyperdasia of ineffective erythropoiesis in homocygotic beta-thalassemia, hereditary non-spherocytic hemolytic anemia caused by pyruvate kinase deficiency and some sideroblastic anemias increased 59 Fe 2+ absorption is a reliable measure of exhausted iron stores. In these exceptional cases differential diagnosis between sideroachrestic and siderosensitive iron deficiency anemia can be made by measurement of serum iron and serum ferritin respectively. The etiology of iron deficiency is to be cleared by measurement of 59 Fe absorption from 59 Fe 2+ and 59 Fe-marked meat with consecutive estimation of whole body 59 Fe elimination. Shortly after completion or during oral iron therapy serum ferritin concentration is not suitable to evaluate the content of iron stores. (orig.) [de

Full Text Available Purpose. To compare serum levels of malondialdehyde (MDA in patients with wet age-related macular degeneration (wAMD, patients with dry AMD (dAMD, and patients without AMD and to evaluate the efficacy of nutritional supplementation for treating elevated serum MDA in patients with wAMD. Methods. MDA levels were measured in sera from 20 patients with wAMD, 20 with dAMD, and 24 without AMD. Patients with wAMD were randomized to receive or not receive nutritional supplementation (10 patients in each group, and MDA levels were measured after 3 months of treatment. Results. MDA levels in patients with wAMD were significantly greater compared with patients without AMD. In eyes with wAMD, there was a significant correlation between MDA levels and choroidal neovascularization lesion area. Serum MDA levels decreased in most patients that received supplementation and significantly increased in those who did not. Conclusion. Baseline serum MDA levels were elevated in patients with wAMD, and MDA levels were directly correlated with choroidal neovascularization lesion area. In addition, nutritional supplementation appeared to exert a protective effect against oxidative stress in patients with wAMD.

Neurologic sequelae associated with foscarnet therapy.

Science.gov (United States)

Lor, E; Liu, Y Q

1994-09-01

To report three cases of possible foscarnet-induced neurologic sequelae. We report two cases of seizures and one case of hand cramping and finger paresthesia after starting foscarnet therapy with no evidence of predisposing risk factors, such as serum laboratory abnormalities, renal dysfunction, or known central nervous system (CNS) involvement. All three patients had stable laboratory values during therapy and when the neurologic adverse effects occurred. All patients were receiving appropriate dosages of foscarnet. The incidence of seizures in AIDS patients was reviewed. A history of CNS lesions, infections, and/or AIDS per se may increase the risk of a neurologic adverse effect while receiving foscarnet therapy. Acute ionized hypocalcemia may cause these neurologic adverse effects. Ionized hypocalcemia is transitory, is related to the rate of foscarnet infusion, and may not be reflected as a change in total serum calcium concentration. Foscarnet probably contributed to the neurologic adverse effects reported here. Foscarnet may need to be administered at a slower rate than is recommended by the manufacturer. Electrolytes must be monitored closely; however, a neurologic adverse effect may not be foreseen.

Chemerin has been linked to adiposity, and insulin resistance (IR) which are the common characteristics of polycystic ovary syndrome (PCOS). Chemerin also shows inhibitory action on follicular steroidogenesis. We investigated the associations between chemerin and IR or polycystic ovary morphology in patients with PCOS. A total of 148 women with newly diagnosed PCOS using Rotterdam criteria and 88 healthy individuals were enrolled. The recruited patients with PCOS were further stratified by tertiles of serum chemerin concentrations as follows: Group 1 ( 30.27 ng/ml). Compared to controls, women with PCOS in each tertile had higher serum chemerin concentrations. By linear regression analysis, homeostasis model assessment-insulin resistance and ovarian volume showed significant associations with chemerin after adjusting for confounding factors (β = 0.257, P = 0.028; β = 0.276, P = 0.005, respectively). The odds ratios (ORs) for ovarian volume excess gradually increased across increasing tertiles of chemerin in the adjusted model [Group 1: reference; Group 2: OR 1.602; 95% confidence interval (CI): 1.170–2.194; Group 3: OR 1.857; 95% CI: 1.335-2.583]. Patients with PCOS showed increased serum chemerin concentrations as compared to healthy women. Individuals with higher chemerin tended to have higher risk for ovarian volume excess in patients with PCOS, regardless of adiposity.

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

Milrinone is a selective inhibitor of the cAMP-specific phosphodiesterase III isoenzyme in myocardium and vascular smooth muscle. Milrinone administration following heart transplantation is routine practice. The purpose of this study was to evaluate the influence of milrinone therapy on splanchnic perfusion following heart transplantation. There were 12 patients (10 males and 2 females) with a mean age of 42 ± 12 who underwent heart transplantation. Milrinone parenteral following surgery was started after surgery and continued for the next 67 ± 4 h. Repeated Swann-Ganz measurements and control transthoracic echocardiography were performed. Blood samples were taken to estimate level of lactic acid (LA), liver transaminases, serum amylase, and GFR ratio. The mean time of milrinone administration was 67 ± 4 h. The serum LA increase following milrinone discontinuation was 1.7 ± 0.7 mmol/dm(3) vs. 3.8 ± 0.9 mmol/dm(3), (pmilrinone discontinuation was 79 ± 30 IU/L vs. 135 ± 55 IU/L, pmilrinone withdrawn. There was a progressive increase in serum amylase levels after milrinone was withdrawn (80.6 ± 29 IU/L vs. 134 ± 45 IU/L, pMilrinone withdrawal during the postoperative period was associated with deterioration of splanchnic perfusion, as shown by a transient increase in lactic acid and serum increase of aminotransferases (ALT/ASP) concentration and amylase activity. The study results show the extracardiac effects of milrinone therapy.

Increased serum C-reactive protein (CRP), an independent predictor of coronary heart disease, was reported in women with polycystic ovary syndrome (PCOS). It remains unclear whether this finding is due to the association between PCOS and either insulin resistance, obesity, or androgen excess, which are all common features of this condition. The aims of this study were to assess whether increased serum CRP is a specific feature of PCOS and to investigate the mechanisms underlying this association. Serum high-sensitivity CRP (hs-CRP) was measured in 86 hyperandrogenic women (age 21.6+/-4.2 years, body mass index (BMI) 23.6+/-3.5 kg/m2), 50 with PCOS and 36 with idiopathic hyperandrogenism (HA). Thirty-five BMI-matched healthy women were also studied as controls. In these subjects, endocrine and metabolic profiles were assessed. In all hyperandrogenic subjects and 14 controls, insulin sensitivity was measured by the glucose clamp technique. Body fat was measured by bioelectrical impedance. Hs-CRP concentrations were higher in PCOS women (3.43+/-2.01 mg/l) than in HA subjects and healthy women (2.43+/-1.04, PPCOS). In multiple regression analyses, increased serum hs-CRP was independently predicted by higher body fat and lower insulin sensitivity. However, in lean women, serum-free testosterone was an additional, negative, predictive variable. PCOS is accompanied by a low-grade chronic inflammation. Body fat appears the main determining factor of this finding, which is only partly explained by insulin resistance. At least in lean women, androgen excess per se seems to play an additional, possibly protective, role in this association.

A radioimmunoassay for serum ursodeoxycholic conjugates using an iodine-125 ligand has been developed. The bile acid was present in normal fasting serum (0.19 +- SD 0.19 ..mu..mol/l, n=24) and 2-hour post-prandial serum (0.8 +- SD 0.8 ..mu..mol/l, n=16). Gallstone patients undergoing oral ursodeoxycholic acid therapy had significantly higher post-prandial serum levels (21.5 +- SD 14.0 ..mu..mol/l, n=15) by radioimmunoassay. Gas liquid chromatography analysis indicated that in normal serum ursodeoxycholic acid was totally conjugated, whereas sera from gallstone patients contained a proportion as the free bile acid (10.2 +- SD 8.1 ..mu..mol/l, n=15). Following an oral dose of ursodeoxycholic acid, both unconjugated and conjugated forms of the bile acid appeared in the serum of healthy individuals.

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

Full Text Available Sustained-release theophylline pellets formulation for once-daily evening administration significantly improved patients compliance and adjusted serum levels profile of the drug. The patients conversion from i.v. to p.o. therapy is one of the most critical steps in the treatment of asthma according to its chronopathophysiological character. In our study we have examined safety and efficiency of this conversion in twelve hospitalised asthmatic patients who were given the new sustained-release theophylline pellets formulation for once-daily evening administration. The lung function parameters (FEV1, VC, RV, and Rt and serum theophylline concentrations were monitored. So, the values obtained for the last day of i.v. therapy and the fifth day of p.o. therapy were compared. We found that 75% of the patients had no change or improved lung function on the conversion. Our results indicate that this conversion from i.v. to p.o. theophylline therapy is safe and could be efficacious. Also, the maximum theophylline serum levels could safely be predicted by measuring only one serum concentration in p.o. therapy with sustained-release theophylline pellets formulation for once-daily evening administration.

The efficiency of the therapy of psychiatric diseases is estimated using the fluorescence measurements of the conformational changes of human serum albumin in the course of medical treatment. The fluorescence decay curves of the CAPIDAN probe (N-carboxyphenylimide of the dimethylaminonaphthalic acid) in the blood serum are measured. The probe is specifically bound to the albumin drug binding sites and exhibits fluorescence as a reporter ligand. A variation in the conformation of the albumin molecule substantially affects the CAPIDAN fluorescence decay curve on the subnanosecond time scale. A subnanosecond pulsed laser or a Pico-Quant LED excitation source and a fast photon detector with a time resolution of about 50 ps are used for the kinetic measurements. The blood sera of ten patients suffering from depression and treated at the Institute of Psychiatry were preliminary clinically tested. Blood for analysis was taken from each patient prior to the treatment and on the third week of treatment. For ten patients, the analysis of the fluorescence decay curves of the probe in the blood serum using the three-exponential fitting shows that the difference between the amplitudes of the decay function corresponding to the long-lived (9 ns) fluorescence of the probe prior to and after the therapeutic procedure reliably differs from zero at a significance level of 1% ( p < 0.01).

Serum-prostate specific antigen (PSA) levels have been used for many years as a biomarker for prostate cancer. This usage is under scrutiny due to the fact that elevated PSA levels can be caused by other conditions such as benign prostatic hyperplasia and infections of or injury to the prostate. As a result, the identification of specific pathogens capable of increasing serum levels of PSA is important. A potential candidate responsible for elevated PSA is human herpesvirus 8 (HHV-8). We have reported previously that HHV-8 is capable of infecting and establishing a latent infection in the prostate. In this current study we test the hypothesis that HHV-8 infection is associated with elevated PSA levels. Circulating cytokine levels between men with elevated PSA and controls are also compared. HHV-8 serostatus was determined among men with elevated serum PSA (≥4 ng/ml; n = 168, no prostate cancer on biopsy) and age-matched controls (PSA PSA and 85 controls). Men with an elevated serum PSA were significantly more likely to be HHV-8 seropositive (42.9%) than the age-matched cancer-free men (22.2%; OR 2.51; 95%CI 1.48-4.29, P = 00001). Comparison of circulating cytokine levels between men with elevated serum PSA and controls indicated that elevated serum PSA is associated with a pro-inflammatory response with a mixed Th1/Th2 response while HHV-8 infection was associated with significantly higher levels of IL12p70, IL-10, and IL-13 indicating a Th2 immune response. We found a significant association between HHV-8 infection and increased levels of serum PSA. In an age of patient-centered medicine, men with an elevated serum PSA should be considered for HHV-8 serology testing to determine if HHV-8 is responsible for the elevated PSA.

To investigate immunological function change in Graves' disease (GD) patients with hypothyroidism within one year after 131 I treatment, and evaluate the relationship between the 131 I treatment and autoimmune thyroid disease. Serum levels of IL-18, TRAb and TPOAb in 41 patients with GD were determined by EIA, IRMA and CLIA, thyroid weight (TDW) were measured by B ultrasonic instrument. The patients were divided into two groups based on whether appear the early hypothyroidism after 131 I treatment during 6-12 months graded as: the hypothyroidism group in 13 and the recovery group in 28; 25 healthy people as control group. Results showed that the serum levels of IL-18 and TRAb in hypothyroidism group and recovery group were significantly increased before 131 I treatment compared with control group (P 3 , FT 4 , sTSH, TDW and 131 I dosage were not significant differences (P>0.05). The serum levels of IL-18 in two groups were decreased (P 131 I treatment (P 3 , FT 4 , TDW(r=0.372 P 131 I therapy and 6/13 after therapy, and in the recovery group were 10/28 before therapy and 12/28 after therapy. These data suggest that radiation has a little influence on GD patients for adjusting immune system during 6-12 months after 131 I treatment. The changes of serum IL-18 and combine with serum TRAb and TPOAb might be valuable implication for assessing the effect and prognosis of 131 I treatment in patients with GD hyperthyroidism.

The M-protein is the major reference measure for response in multiple myeloma (MM) and its correct interpretation is key to clinical management. The emergence of oligoclonal banding is recognized as a benign finding in the postautologous stem cell transplantation setting (ASCT) for MM but its significance during non-myeloablative therapy is unknown. In a study of the immunomodulatory combination BiRD, (lenalidomide and dexamethasone with clarithromycin), we frequently detected the emergence of mono- and oligo-clonal immunoglobulins unrelated to the baseline diagnostic M-protein. The new M-proteins seen on serum immunofixation electrophoresis were clearly different in either heavy or light chain component(s) from the original M-spike protein and were termed atypical serum immunofixation patterns (ASIPs). Overall, 24/72 (33%) patients treated with BiRD developed ASIPs. Patients who developed ASIPs compared with patients treated with BiRD without ASIPs, had a significantly greater overall response (100% vs. 85%) and complete response rates (71% vs. 23%). ASIPs were not associated with new clonal plasma cells or other lymphoproliferative processes, and molecular remissions were documented. This is the first time this phenomenon has been seen with regularity in non-myeloablative therapy for MM. Analogous to the ASCT experience, ASIPs do not signal incipient disease progression, but rather herald robust response.

Mesenchymal stromal cells (MSCs) are being investigated as potential cell therapies for many different indications. Current methods of production rely on traditional monolayer culture on tissue-culture plastic, usually with the use of serum-supplemented growth media. However, the monolayer culturing system has scale-up limitations and may not meet the projected hundreds of billions to trillions batches of cells needed for therapy. Furthermore, serum-free medium offers several advantages over serum-supplemented medium, which may have supply and contaminant issues, leading to many serum-free medium formulations being developed. We cultured seven MSC lines in six different serum-free media and compared their growth between monolayer and microcarrier culture. We show that (i) expansion levels of MSCs in serum-free monolayer cultures may not correlate with expansion in serum-containing media; (ii) optimal culture conditions (serum-free media for monolayer or microcarrier culture) differ for each cell line; (iii) growth in static microcarrier culture does not correlate with growth in stirred spinner culture; (iv) and that early cell attachment and spreading onto microcarriers does not necessarily predict efficiency of cell expansion in agitated microcarrier culture. Current serum-free media developed for monolayer cultures of MSCs may not support MSC proliferation in microcarrier cultures. Further optimization in medium composition will be required for microcarrier suspension culture for each cell line. Copyright © 2015 International Society for Cellular Therapy.

Full Text Available Background The main causes of maternal mortality in Indonesia are pre-eclampsia, hemorrhage, and infection. Oxidative stress has a primary role in pre-eclampsia and one of its parameters is 8-isoprostane serum level. The objective of this study is to measure 8-isoprostane and to analyze the relationship between 8-isoprostane level and birth weight in pre-eclampsia. Methods A cross-sectional study involving 23 pre-eclampsia and 29 normotensive pregnant women with normal or cesarean delivery at Dr. Kariadi Hospital Semarang from January to May 2011. Collected maternal blood samples were assessed for 8-Isoprostane levels by means of a specific ELISA kit. Neonatal birth weight was measured immediately after delivery by means of calibrated baby scales. Differences in 8-isoprostane levels between pre-eclampsia and normotensive women were assessed using independent t-test for normal distributed data, and the Mann-Whitney test for non-normally distributed data. Results Mean 8-isoprostane level was significantly higher in women with pre-eclampsia than in normotensive women (62.52 ± 12.19 pg/mL vs 28.64 ± 8.81 pg/mL (p<0.05. Low birth weight was twice as frequent in pre-eclampsia than in normotensives. There was no correlation between 8-isoprostane serum level and neonatal birth weight in pre-eclampsia. Conclusion The level of 8-isoprostane was higher in pre-eclampsia than in normotensives. It is recommended to conduct further studies to determine whether 8-isoprostane may be used as a predictive marker of pre-eclampsia.

Serum sex hormones may be related to the risk of several diseases including osteoporosis, heart disease, and breast and endometrial cancer in postmenopausal women. In the current report, the authors examined the epidemiology of serum sex hormones in 176 healthy, white postmenopausal women (mean age 58 years) recruited from the metropolitan Pittsburgh, Pennsylvania, area. The data were collected during 1982-1983; none of the women were on estrogen replacement therapy. Serum concentrations of estrone, estradiol, testosterone, and androstenedione were measured by a combination of extraction, column chromatography, and radioimmunoassay. Neither age nor time since menopause was a significant predictor of sex hormones. The degree of obesity was a major determinant of estrone and estradiol. The estrone levels of obese women were about 40% higher than the levels of nonobese women. There was a weak relation between obesity and the androgens. Cigarette smokers had significantly higher levels of androstenedione than nonsmokers, with little difference in serum estrogens between smokers and nonsmokers. Both estrone and estradiol levels tended to decline with increasing alcohol consumption. Physical activity was an independent predictor of serum estrone. More active women had lower levels of estrone. There was a positive relation of muscle strength with estrogen levels. The data suggest interesting relations between environmental and lifestyle factors and serum sex hormones. These environmental and lifestyle factors are potentially modifiable and, hence, if associations between sex hormones and disease exist, modification of these factors could affect disease risks

The indication for testosterone therapy in aging hypogonadal men without hypothalamic, pituitary, or testicular disease remains to be elucidated. The aim of this study was to investigate the effect of testosterone therapy on insulin sensitivity, substrate metabolism, body composition, and lipids...... lipid oxidation (b = 5.65 mg/min/m(2), p = 0.045) increased and basal glucose oxidation (b = -9.71 mg/min/m(2), p = 0.046) decreased in response to testosterone therapy even when corrected for changes in LBM. No significant changes in insulin-stimulated Rd was observed (b = -0.01mg/min/m(2), p = 0.......92). Testosterone therapy increased muscle mass and lipid oxidation in aging men with low normal bioavailable testosterone levels; however, our data did not support an effect of testosterone on whole-body insulin sensitivity using the euglycemic hyperinsulinemic clamp technique....

Full Text Available Noise, one of the main components of modern society, has become an important environmental problem. Noise is not only an irritating sound, but also a stress factor leading to serious health problems. In this study, we have investigated possible effects of rosuvastatin, a 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor, thought to have an antioxidant effect, on noise-induced oxidative stress in the serum of rat models. Thirty-two male Wistar albino rats were used. In order to ease their adaptation, 2 weeks before the experiment, the rats were divided into four groups (with eight rats per each group: Noise exposure plus rosuvastatin usage, only noise exposure, only rosuvastatin usage and control. After the data had been collected, oxidant (Malondialdehyde, nitric oxide [NO], protein carbonyl [PC] and antioxidant (superoxide dismutase [SOD], glutathione peroxidase [GSH-PX], catalase [CAT] parameters were analyzed in the serum. Results indicated that SOD values were found to be significantly lower, while PC values in serum were remarkably higher in the group that was exposed to only noise. GSH-Px values in serum dramatically increased in the group on which only rosuvastatin was used. During noise exposure, the use of rosuvastatin caused significantly increased CAT values, whereas it resulted in reduced PC and NO values in serum. In conclusion, our data show that noise exposure leads to oxidative stress in rat serum; however, rosuvastatin therapy decreases the oxidative stress caused by noise exposure.

Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid (n-3 PUFA) which has been shown to raise seizure thresholds following acute administration in rats. The aims of the present experiment were the following: 1) to test whether subchronic DHA administration raises seizure threshold in the maximal pentylenetetrazol (PTZ) model 24h following the last injection and 2) to determine whether the increase in seizure threshold is correlated with an increase in serum and/or brain DHA. Animals received daily intraperitoneal (i.p.) injections of 50mg/kg of DHA, DHA ethyl ester (DHA EE), or volume-matched vehicle (albumin/saline) for 14days. On day 15, one subset of animals was seizure tested in the maximal PTZ model (Experiment 1). In a separate (non-seizure tested) subset of animals, blood was collected, and brains were excised following high-energy, head-focused microwave fixation. Lipid analysis was performed on serum and brain (Experiment 2). For data analysis, the DHA and DHA EE groups were combined since they did not differ significantly from each other. In the maximal PTZ model, DHA significantly increased seizure latency by approximately 3-fold as compared to vehicle-injected animals. This increase in seizure latency was associated with an increase in serum unesterified DHA. Total brain DHA and brain unesterified DHA concentrations, however, did not differ significantly in the treatment and control groups. An increase in serum unesterified DHA concentration reflecting increased flux of DHA to the brain appears to explain changes in seizure threshold, independent of changes in brain DHA concentrations.

Full Text Available Introduction: Adults treated with topiramate may develop nephrolithiasis, but its frequency in children on topiramate is unknown. Topiramate inhibits renal carbonic anhydrase, which can lead to renal tubular acidosis and hypercalciuria. We studied 40 consecutive children who initiated topiramate therapy for seizures between January 1997 and February 2003, followed for a mean of 36 months. Methods: Serum electrolytes, urinary calcium/creatinine ratios, and renal ultrasonography were performed before topiramate and every 6 months thereafter. Results: Four children developed nephrolithiasis and/or nephrocalcinosis, which resolved on discontinuation of topiramate. In 40 patients, the mean urinary calcium/creatinine ratio increased over time (P 0.21 were compared with the 14 children with baseline normal urinary calcium excretion. A greater increase in urinary calcium/creatinine ratios occurred in hypercalciuric children (P < 0.001 and a greater decrease in serum bicarbonate levels occurred in the hypercalciuric children (P < 0.05 compared with children with baseline normal calcium excretion. Greater urinary calcium excretion was associated with increasing doses of topiramate (P = 0.039. Conclusion: Our study shows that long-term therapy with topiramate in children is associated with persistent hypercalciuria and metabolic acidosis, which can lead to nephrocalcinosis and/or nephrolithiasis. All children initiating topiramate therapy should have baseline and follow-up urinary calcium/creatinine studies, serum electrolytes, and periodic renal ultrasonography, if the urinary calcium/creatinine ratio increases to a level above normal for age.

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

Chronic spontaneous urticaria is triggered by many direct and indirect aggravating factors including autoreactive/autoimmune mechanisms, infections, non-allergic and pseudoallergic intolerance reactions. However, the role of neuroimmune mechanisms in chronic spontaneous urticaria so far is unclear. Thus, we wanted to address the regulation of the neurotrophin brain-derived neurotrophic factor (BDNF) in serum and inflammatory skin of patients with chronic spontaneous urticaria in comparison to subjects with healthy skin. Fifty adult patients with chronic spontaneous urticaria and 23 skin-healthy subjects were studied. Chronic spontaneous urticaria was defined as recurrent weals for more than 6 weeks. Autologous serum skin test was performed in all patients with chronic spontaneous urticaria and BDNF serum levels were analysed by enzyme immunoassay in all subjects. Furthermore, skin biopsies were taken from weals of eight patients with chronic spontaneous urticaria as well as from healthy skin of eight controls to evaluate the expression of BDNF and its receptors including tyrosine kinase (trk) B and pan-neurotrophin receptor p75(NTR) by immunohistochemistry. BDNF serum levels were detectable in all subjects studied. However, BDNF levels were significantly higher in patients with chronic spontaneous urticaria compared to non-atopic skin-healthy controls (Pchronic spontaneous urticaria compared with controls (Pchronic spontaneous urticaria and controls and no difference in BDNF serum levels between autologous serum skin test-positive (n=23) and -negative (n=27) patients with chronic spontaneous urticaria. This study shows that BDNF is increased in serum and diseased skin of patients with chronic spontaneous urticaria, suggesting a role for neurotrophins in the pathophysiology of this chronic inflammatory skin disease. Further studies are needed to address the functional role of BDNF on key target effector cells in chronic spontaneous urticaria to establish new

Nonenzymatic advanced glycation and oxidation end-products, advanced glycation end-products (AGEs), impart a potent impact on vessels and other tissues in diabetic state and in euglycaemic conditions with increased oxidative stress. Insulin resistant (IR) polycystic ovary syndrome (PCOS) women, have elevated serum AGEs, increased receptor (RAGE) expression, and increased deposition with differential localization in the polycystic ovarian tissue (theca and granulosa) compared to normal. To determine whether the raised AGE levels in noninsulin resistant women with PCOS is a distinct finding compared with those presenting the isolated components of the syndrome and among PCOS subphenotypes. Noninsulin resistant women were selected in order to show that serum AGEs are elevated in PCOS independently of the presence of IR. Clinical trial. One hundred and ninety-three age- and BMI-matched young lean noninsulin resistant women were studied. Among them, 100 women were diagnosed with PCOS according to Rotterdam criteria, and divided to subphenotypes (hyperandrogenaemia with or without PCO morphology and with or without anovulation). Sixty-eight women with the isolated components of the PCOS phenotype were also studied along with 25 healthy women. Serum AGE levels, metabolic, hormonal profiles and intravaginal ultrasound were determined in all subjects. The studied population did not differ in BMI, fasting insulin concentration, waist : hip and glucose : insulin ratios. PCOS women exhibited statistically higher AGEs levels (7.96 +/- 1.87 U/ml, P PCOS, serum AGEs are distinctly elevated compared with women having the isolated characteristics of the syndrome. No difference was observed between PCOS subphenotypes. As chronic inflammation and increased oxidant stress have been incriminated in the pathophysiology of PCOS, the role of AGEs as inflammatory and oxidant mediators, may be linked with the metabolic and reproductive abnormalities of the syndrome.

One hundred twenty-seven newborn infants requiring parenteral nutrition were randomly assigned to receive differing amounts of zinc (40 to 400 micrograms/kg/day) and copper (20 or 40 micrograms/kg/day) supplementation within five birth weight groups (600 to 2,500 gm). The serum zinc concentration remained relatively constant in the group receiving the most zinc supplementation after two weeks of therapy, but declined sharply in the groups receiving less supplementation. No effect of increased copper intake was noted on ceruloplasmin values, but a difference in serum copper concentrations was noted at two weeks. No correlation was noted between serum zinc and copper values or among those for serum zinc, retinol-binding protein, and prealbumin. Reference ranges were defined for serum zinc, copper, retinol-binding protein, prealbumin, and ceruloplasmin in the preterm infant.

This study aimed to evaluate the effects of monotherapy with valproate or oxcarbazepine on the linear growth of children with idiopathic epilepsy. Antiepileptic treatment with valproate or oxcarbazepine was initiated in 76 patients. These were evaluated at baseline and at 6 and 18 months after commencement of therapy to determine height standard deviations (height z-scores). Serum ghrelin, insulin-like growth factor-1, and insulin-like growth factor-binding protein-3 levels were measured. In prepubertal patients receiving oxcarbazepine, height z-scores were elevated after 6 and 18 months of therapy (p = 0.008 and p = 0.001, respectively); in pubertal patients, a significant increase was noted at the 18th month of therapy (p = 0.004). In prepubertal patients receiving oxcarbazepine, serum standardized insulin-like growth factor-1 and insulin-like growth factor-binding protein-3 levels were significantly higher at the 18th month of therapy compared with baseline (p = 0.005 and p = 0.004, respectively). In puber-tal patients receiving valproate, serum ghrelin levels were significantly decreased at the 18th month of therapy compared with baseline (p = 0.006). Exposure to oxcarbazepine stimulated linear growth in epileptic patients through mechanisms involving the release of insulin-like growth factor-1 and insulin-like growth factor-binding protein-3. In contrast, expo-sure to valproate did not affect linear growth, but did lead to a decrease in serum ghrelin levels.

Valproate is one of the most frequently used anticonvulsive drugs in children and adults. Valproate is a generally well tolerated medication. However, encephalopathy with or without hyperammonemia is one of its rare adverse events. We present a 7-year-old girl who suffered from epilepsy with generalized tonic-clonic seizures and absence epilepsy. She was initially treated with topiramate. Methylprednisolone pulse therapy and long-term therapy with valproate were initiated due to an increase of seizure frequency. At day 5 of therapy, a further increase of seizure frequency was observed followed by lethargy and somnolence. Liver enzymes remained within normal range, but ammonia serum levels increased to a maximum of 544 mmol/l. Discontinuing valproate and starting potassium-benzoate and sodium-phenylbutyrate improved the clinical condition and ammonia serum levels. Haemodialysis was not required. Cranial magnetic resonance imaging ruled out brain edema. The patient was further on successfully treated with a combination of both, topiramate and levetiracetam. Seizures did not recur and development was normal until now (3 years later). To the best of our knowledge, we observed the highest ammonia serum levels ever reported in valproate-induced hyperammonemia with a complete remission of the subsequent encephalopathy. Topiramate might increase the risk of valproate-induced encephalopathy by carbonic anhydrase inhibition.

The objective of this study was to investigate the usefulness of serum KL-6 and SP-D in the diagnosis of radiation pneumonitis. We measured serum KL-6 and SP-D in patients undergoing radiation therapy of the chest, primarily for lung cancer, in the Department of Radiology, Osaka Medical College and compared the results with the findings on plain chest X-ray films and thoracic computed tomography conducted at the same time. The sensitivity of serum KL-6 and SP-D for diagnosing radiation pneumonitis were 68.2% and 70.0%, respectively, the specificity were 86.6% and 80.0%, and the accuracy were 82.0% and 77.8%. Examination of the relationship between lesion extent and activity and serum KL-6 showed that serum KL-6 values were higher when the lesion extended beyond the irradiation field than when the lesion was confined to within the irradiation field and that the value tended to be lower for old lesions than for active lesions. In patients with radiation pneumonitis in whom serum KL-6 and SP-D could be measured over time, KL-6 tended to increase after the lesion was discovered by imaging, whereas SP-D increased prior to this in many cases. Examination of the comparison between before radiotherapy and just after radiotherapy in the patients with radiation pneumonitis showed that SP-D had a consistent tendency to increase. Both serum KL-6 and SP-D had a satisfactory degree of sensitivity and specificity for diagnosing radiation pneumonitis. Serum KL-6 correlated with the extent and activity of the lesions. The results suggested that serum SP-D may be helpful for the early detection of radiation pneumonitis. (author)

Hepatic fatty infiltration appears as an area of increased echogenicity. And many factors concerned to fatty infiltration. With 65 cases of fatty liver and 42 cases of normal group, we analyzed fatty liver with grading and attempt to find relations between grade of fatty liver and levels of body index, serum triglyceride, and serum lipid. And compared fatty liver with normal control group. Patients with fatty liver are higher percentage of supra-normal value in body index, serum lipid, and serum triglyceride than normal control group. As fatty infiltration progressed, serum lipid, serum trig-lyceride and body index are also increased. Conclusively ultrasonographic examination of liver with serum triglyceride, serum lipid, and body index are simple method, useful follow-up examination of fatty liver, and preventive routine check-up of chronic liver disease

The conductivity is largely determined by ion levels in water, predominant ion being Ca(2+) in the freshwaters. For this reason, the effects of copper were evaluated as a matter of conductivity of exposure media in the present study. Thus, freshwater fish Oreochromis niloticus were exposed to copper in differing conductivities (77, 163 and 330 μS/cm), using acute (0.3 μM, 3 d) and chronic (0.03 μM, 30 d) exposure protocols. Following the exposure serum parameters of fish were measured. Data showed that there was no significant alteration (P>0.05) in serum parameters of control fish. However, activities of ALP, ALT and AST decreased significantly at the lower conductivities in chronic copper exposure, but not in acute ones. Protein levels did not differ significantly in any of the exposure conditions. However, Cu exposure at the lowest conductivity sharply increased the levels of glucose in the acute exposure, while there was no significant difference in the chronic exposure. Cholesterol levels decreased only at the lower conductivities in chronic exposure, but increased in acute exposure. Similarly, triglyceride levels increased in acute exposures and decreased in chronic exposures at the lowest conductivity. There was no change in Na(+) levels, while there was an increase in K(+) levels and a decrease in Ca(2+) level at the lowest conductivity of acute exposures. However, Cl(-) levels generally decreased at the higher conductivities of chronic exposures. There was a strong negative relationship between significant altered serum parameters and water conductivity. In conclusion, this study showed that copper exposure of fish at lower conductivities caused more toxicities, indicating the protective effect of calcium ions against copper toxicity. Data suggest that conductivity of water may be used in the evaluation of metal data from different waters with different chemical characteristics. Copyright © 2015 Elsevier B.V. All rights reserved.

We aimed to detect the role of obesity on the healing response to periodontal therapy in terms of serum lipids, C-reactive protein (CRP) and both serum and gingival crevicular fluid adipocytokines. Thirty patients with periodontitis with (CPO) (n = 15) and without (n = 15) obesity and 15 healthy controls were included. Serum high-density lipoprotein, low-density lipoprotein, triglyceride, CRP levels and levels of adiponectin, interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL-10 were evaluated before and 3 mo after initial periodontal therapy. Clinical periodontal measurements were also recorded at baseline and 3 mo. Periodontal parameters improved significantly in both periodontitis groups with or without obesity (p 0.05) and change in numbers of sites with probing depth ≥ 4 mm. High-density lipoprotein significantly increased in both groups (p > 0.05). CRP decreased significantly solely in the normal weight group. IL-6, IL-10 and TNF-α levels in gingival crevicular fluid improved significantly based on therapy in both groups (p periodontitis without obesity. Patients with CPO respond to periodontal therapy as well as the non-obese controls. This similar response is accompanied with consistent adipokine levels in gingival crevicular fluid. However, obesity affects the CRP and serum adipocytokine levels in response to therapy. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Although Lepidium meyenii (maca), a plant growing in Peru's central Andes, has been traditionally used for enhancing fertility and reproductive performance in domestic animals and human beings, effects of maca on reproductive organs are still unclear. This study examined whether feeding the hydroalcoholic extract powder of maca for 6 weeks affects weight of the reproductive organs, serum concentrations of testosterone and luteinising hormone (LH), number and cytoplasmic area of immunohistochemically stained Leydig cells, and steroidogenesis of cultured Leydig cells in 8-week-old male rats. Feeding the extract powder increased weight of seminal vesicles, serum testosterone level and cytoplasmic area of Leydig cells when compared with controls. Weight of prostate gland, serum LH concentration and number of Leydig cells were not affected by the maca treatment. The testosterone production by Leydig cells significantly increased when cultured with 22R-hydroxycholesterol or pregnenolone and tended to increase when cultured with hCG by feeding the extract powder. The results show that feeding the hydroalcoholic extract powder of maca for 6 weeks increases serum testosterone concentration associated with seminal vesicle stimulation in male rats, and this increase in testosterone level may be related to the enhanced ability of testosterone production by Leydig cells especially in the metabolic process following cholesterol. © 2015 Blackwell Verlag GmbH.

A diagnosis of Addison's disease means lifelong dependence on daily glucocorticoid and mineralocorticoid therapy and is associated with increased morbidity and mortality as well as a risk of unexpected adrenal crisis. The objective of the study was to determine whether immunomodulatory therapy at an early stage of autoimmune Addison's disease could lead to preservation or improvement in adrenal steroidogenesis. This was an open-label, pilot study of B lymphocyte depletion therapy in new-onset idiopathic primary adrenal failure. Doses of iv rituximab (1 g) were given on d 1 and 15, after pretreatment with 125 mg iv methylprednisolone. Six patients (aged 17-47 yr; four females) were treated within 4 wk of the first diagnosis of idiopathic primary adrenal failure. Dynamic testing of adrenal function was performed every 3 months for at least 12 months. Serum cortisol levels declined rapidly and were less than 100 nmol/liter (3.6 μg/dl) in all patients by 3 months after B lymphocyte depletion. Serum cortisol and aldosterone concentrations remained low in five of the six patients throughout the follow-up period. However, a single patient had sustained improvement in both serum cortisol [peak 434 nmol/liter (15.7 μg/dl)] and aldosterone [peak 434 pmol/liter (15.7 ng/dl)] secretion. This patient was able to discontinue steroid medications 15 months after therapy and remains well, with improving serum cortisol levels 27 months after therapy. New-onset autoimmune Addison's disease should be considered as a potentially reversible condition in some patients. Future studies of immunomodulation in autoimmune Addison's disease may be warranted.

Full Text Available Background & objectives: Iron deficiency anaemia (IDA is the most common nutritional deficiency in pregnancy. Prophylactic oral iron is recommended during pregnancy to meet the increased requirement. In India, women become pregnant with low baseline haemoglobin level resulting in high incidence of moderate to severe anaemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anaemia are to be treated with parentral iron therapy. This study was undertaken to evaluate the response and effect of intravenous iron sucrose complex (ISC given to pregnant women with IDA. Methods: A prospective study was conducted (June 2009 to June 2011 in the department of Obstetrics & Gynecology, All India Institute of Medical Sciences, New Delhi. One hundred pregnant women with haemoglobin between 5-9 g% with diagnosed iron deficiency attending antenatal clinic were given intravenous iron sucrose complex in a dose of 200 mg twice weekly schedule after calculating the dose requirement. Results: The mean haemoglobin raised from 7.63 ± 0.61 to 11.20 ± 0.73 g% (P<0.001 after eight wk of therapy. There was significant rise in serum ferritin levels (from 11.2 ± 4.7 to 69 ± 23.1 μg/l (P<0.001. Reticulocyte count increased significantly after two wk of starting therapy (from 1.5 ± 0.6 to 4.6±0.8%.Other parameters including serum iron levels and red cell indices were also improved significantly. Only one woman was lost to follow up. No major side effects or anaphylactic reactions were noted during study period. Interpretation & conclusions: Parentral iron therapy was effective in increasing haemoglobin, serum ferritin and other haematological parameters in pregnant women with moderate anaemia. Intravenous iron sucrose can be used in hospital settings and tertiary urban hospitals where it can replace intramuscular therapy due to injection related side effects. Further, long-term comparative studies are required to recommend its

Following radioiodine therapy for Graves' disease, transient elevation of anti-thyrotropin receptor antibody (TRAb) is observed. Elevation of TRAb causes neonatal hyperthyroidism. Serum TRAb levels before radioiodine therapy, 2 months to 1 year, 1 to 2 years, 2 to 3 years, and 3 to 4 years after radioiodine therapy were retrospectively analyzed in 25 women of childbearing age with Graves' disease. The normal range for TRAb is ≤15%. The one patient with serum TRAb levels <10% before radioiodine therapy did not have TRAb levels ≥50% after radioiodine therapy. However, in patients with serum TRAb levels of 10% to 30% before radioiodine therapy (n=8), TRAb were ≥50% in 75.0% 2 months to 1 year after radioiodine therapy, in 25.0% 1 to 2 years after, and in 37.5% 2 to 4 years after. In patients with serum TRAb levels of 30% to 50% before radioiodine therapy (n=3), TRAb levels were ≥50% in 33.3% 2 months to 1 year after radioiodine therapy and in 0.0% 1 to 4 years after. In patients with serum TRAb levels of 50% to 70% before radioiodine therapy (n=6), TRAb were ≥50% in 83.3% 2 months to 1 year after radioiodine therapy, in 66.6% 1 to 2 years after, and in 33.3% 2 to 4 years after. In patients with serum TRAb levels ≥70% before radioiodine therapy (n=7), TRAb levels were ≥50% in 100% 2 months to 1 year after radioiodine therapy, in 85.7% 1 to 2 years after, in 71.4% 2 to 3 years after, and in 57.1% 3 to 4 years after. Serum TRAb levels are more likely to be ≥50% after radioiodine therapy in patients with high serum TRAb levels before radioiodine therapy. (author)

Serum 3,3',5'-triiodothyronine (rT 3 ) was measured with a radioimmunoassay in unextracted serum. The assay was specific and reproducible. The coefficients of variation for three different sera known for high, normal, and low rT 3 concentrations between assays were 4, 6, and 9 percent and within assays 4, 9, and 7 percent, respectively. In euthyroid subjects 20 to 60 years old, rT 3 was 450 +- 200 pg/ml (mean +- SD, n = 83). Serum rT 3 was found to be increased in hyperthyroidism (range: 762 to 2581 pg/ml; n = 11) but also in acute and chronic illness (up to 2400 pg/ml; n = 24) and in anorexia nervosa (536 to 1058 pg/ml; n = 7). In the latter two situations there was mostly an inverse change in serum 3,5,3'-triiodothyronine (T 3 ) which was in the low normal range or decreased. These findings suggest a metabolic control of thryoxine deiodination. A low serum rT 3 was found in 9 of 12 hypothyroid patients and in the serum of one chronically ill patient. Long-term treatment (1 to 7 years) with lithium carbonate slightly reduced serum rT 3 , although the changes were inside the normal range. Kidney function was not found to be necessary for its production, as anephric patients had normal rT 3 values. In addition, hemodialysis increased serum rT 3 , which is probably due to the heparin therapy

The antioxidant mineral selenium (Se was measured in serum samples from 106 IBD patients (53 with ulcerative colitis (UC and 53 with Crohn’s disease (CD and from 30 healthy controls. Serum Se concentrations were significantly lower in UC and CD patients than in healthy controls (p < 0.001 and significantly lower in CD patients than in UC patients (p = 0.006. Se concentrations in patients were significantly influenced by sex, body mass index (BMI, the inflammatory biomarker α-1-antitrypsin, surgery, medical treatment, the severity, extent, and form of the disease and the length of time since onset (p < 0.05. Se concentrations in IBD patients were positively and linearly correlated with nutritional (protein, albumin, prealbumin, cholinesterase and total cholesterol and iron status-related (hemoglobin, Fe and hematocrit parameters (p < 0.05. A greater impairment of serum Se and cardiovascular status was observed in CD than in UC patients. An adequate nutritional Se status is important in IBD patients to minimize the cardiovascular risk associated with increased inflammation biomarkers, especially in undernourished CD patients, and is also related to an improved nutritional and body iron status.

To report the outcomes associated with the use of rabbit anti-dog thymocyte serum in dogs with haematological immune-mediated diseases. Medical records from 2000 to 2016 of patients diagnosed with immune-mediated haemolytic anaemia, immune-mediated thrombocytopenia, pancytopenia and myelofibrosis were reviewed. All dogs had a severe or refractory disease and received rabbit anti-dog thymocyte serum. Lymphocyte counts were used to monitor the immediate anti-thymocyte effect of therapy; long-term patient outcome was recorded. A total of 10 dogs were included. All dogs except one had a notable decrease in their lymphocyte count after rabbit anti-dog thymocyte serum; four of nine had a decrease to less than 10% of the initial lymphocyte count and one dog reached 10·8%. All dogs were discharged from the hospital following their treatment. The dog with no alteration of lymphocyte count following therapy with rabbit anti-dog thymocyte serum had refractory immune mediated haemolytic anemia and was euthanised within two weeks. All other cases achieved clinical remission with immunosuppressive therapy eventually being tapered (3 of 10) or discontinued (6 of 10). Rabbit anti-dog thymocyte serum therapy might be of interest as an adjunctive therapy in refractory immune-mediated diseases and suppressed lymphocyte counts in most dogs. © 2017 British Small Animal Veterinary Association.

Fetal bovine serum (FBS) is commonly used as a serum supplement for culturing human mesenchymal stromal cells (hMSCs). However, human cells grown in FBS, especially for extended periods, risk potential exposure to bovine immunogenic proteins and infectious agents. To address this issue, we investigated the ability of a novel human platelet serum supplement to substitute for FBS in hMSC cultures. Platelet lysate-serum (PL-serum) was converted from platelet lysate-plasma (PL-plasma) that was manufactured from pooled platelet-rich plasma (PRP) apheresis units. Growth factor levels and the number of residual intact platelets in PL-serum and PL-plasma were compared with enzyme-linked immunosorbent assays and flow cytometry, respectively. Proliferation responses of hMSCs cultured in PL-serum, PL-plasma, or FBS were assessed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, the immunophenotype of harvested hMSCs was evaluated by flow cytometry and tri-lineage differentiation potential was evaluated by assessing adipogenic, osteogenic and chondrogenic development. Selected growth factor levels in PL-serum were not significantly different from PL-plasma (P > 0.05). hMSC cultures supplemented with PL-serum had comparable growth kinetics to PL-plasma, and hMSC yields were consistently greater than with FBS. hMSCs harvested from cultures supplemented with PL-serum, PL-plasma or FBS had similar cell surface phenotypes and maintained tri-lineage differentiation potential. PL-serum, similar to PL-plasma, can substitute for FBS in hMSC cultures. Use of PL-serum, in contrast to PL-plasma, has an added advantage of not requiring addition of a xenogeneic source of heparin, providing a completely xeno-free culture medium.

Full Text Available Our previous studies have demonstrated the beneficial effects of Bufei Yishen granules combined with acupoint sticking therapy (the integrated therapy in chronic obstructive pulmonary disease (COPD, but the underlying mechanism remains unclear. Dysfunction of pulmonary surfactant proteins (SPs, including SP-A, SP-B, SP-C, and SP-D may be included in pathophysiology of COPD. This study aimed to explore the mechanism of the integrated therapy on SPs. COPD rat models were established. The treatment groups received Bufei Yishen granules or acupoint sticking or their combination. Using aminophylline as a positive control drug. The levels of SPs in serum, BALF, and lung were measured. The results showed that the integrated therapy markedly reduced the levels of SPs in serum and increased these indicators in the lung. The integrated therapy was better than aminophylline in reducing the levels of SPs and was better than Bufei Yishen granules in reducing SP-A, SP-C, and SP-D in serum. The integrated therapy was better than aminophylline and Bufei Yishen granules in increasing SP-A, SP-B, and SP-D mRNA in the lung. SP-A and SP-D in BALF were positively correlated with PEF and EF50. The levels of SPs are associated with airway limitation. The beneficial effects of the integrated therapy may be involved in regulating pulmonary surfactant proteins.

Serum cell-free DNA concentrations have been reported to increase in many acute diseases as well as in some chronic conditions such as cancer and autoimmune diseases. The aim of this study was to examine whether serum DNA concentrations were elevated in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). The effects of nasal continuous positive airway pressure (nCPAP) on serum DNA were also investigated. One hundred twenty-seven people diagnosed with OSAHS by polysomnography (PSG) were admitted into the OSAHS group, and 52 subjects without OSAHS were recruited for the control group. The OSAHS group was further divided into mild, moderate, and severe OSAHS subgroups based on their apnea-hypopnea index (AHI) during sleep. Ten patients with moderate and severe OSAHS were treated with nCPAP. Serum DNA, interleukin-6 (IL-6), and malonaldehyde (MDA) concentrations were measured and were found to be significantly higher in patients with moderate and severe OSAHS groups than those in the mild OSAHS and control groups (p DNA correlated positively with AHI, oxygen desaturation index (ODI), IL-6, and MDA, and negatively correlated with minimal oxygen saturation (miniSaO(2)) (all p DNA concentrations. After 6 months of nCPAP therapy, serum concentrations of DNA, IL-6, and MDA were significantly decreased (p DNA in patients with OSAHS was positively correlated with disease severity. Serum DNA may become an important parameter for monitoring the severity of OSAHS and effectiveness of therapy.

Some studies have shown potential benefit of vitamin E on platelet function, but several clinical trials failed to show improved cardiovascular outcome with alpha-tocopherol supplementation. Gamma-tocopherol, a major dietary form of vitamin E, may have protective properties different from those of alpha-tocopherol. We compared the effects of supplementation with alpha-tocopherol (500 mg) and a gamma-tocopherol-rich compound (500 mg, containing 60% gamma-tocopherol) on serum and cellular tocopherol concentrations, urinary tocopherol metabolite excretion, and in vivo platelet activation in subjects with type 2 diabetes. Fifty-eight subjects were randomly assigned to receive either 500 mg alpha-tocopherol/d, 500 mg mixed tocopherols/d, or matching placebo. Serum, erythrocyte, and platelet tocopherol and urinary metabolite concentrations were measured at baseline and after the 6-wk intervention. Soluble CD40 ligand, urinary 11-dehydro-thromboxane B2, serum thromboxane B2, soluble P-selectin, and von Willebrand factor were measured as biomarkers of in vivo platelet activation. Serum alpha-tocopherol increased with both tocopherol treatments. Serum and cellular gamma-tocopherol increased 4-fold (P tocopherol group, whereas red blood cell gamma-tocopherol decreased significantly after alpha-tocopherol supplementation. Excretion of alpha-carboxyethyl-hydroxychroman increased significantly after supplementation with alpha-tocopherol and mixed tocopherols. Excretion of gamma-carboxyethyl-hydroxychroman increased significantly after supplementation with mixed tocopherols and after that with alpha-tocopherol, which may reflect the displacement of gamma-tocopherol by alpha-tocopherol due to incorporation of the latter into lipoproteins in the liver. Neither treatment had any significant effect on markers of platelet activation. Supplementation with alpha-tocopherol decreased red blood cell gamma-tocopherol, whereas mixed tocopherols increased both serum alpha-tocopherol and

Background: Hyperuricemia can cause serious health problems including renal insufficiency. Hyperuricemia is associated with many diseases including Hypertension, Diabetes Mellitus, Hypertriglyceridemia and Obesity. Objective of the present study was to study the Association of Serum Uric Acid with Blood Urea and Serum Creatinine. Methods: Eighty subjects, aged above 40, having blood urea more than 40 mg/dl and serum Creatinine more than 1.3 mg/dl were selected. 52.5 % subjects were male. Eighty subjects were selected as control group matching the age and sex with study group with normal blood urea and serum Creatinine. Results: Serum Uric Acid was found to be raised in 33 patients. Mean Serum Uric Acid value was 6.98+-2.021 in males (p<0.05) and 5.054+-2.324 in females (p<0.05). Conclusion: Serum Uric Acid is raised in patients with impaired renal function (p<0.05). Levels of increased Serum Uric Acid were not significantly associated with the cause of renal disease. (author)

RANKL-Targeted Therapies: The Next Frontier in the Treatment of Male Osteoporosis

Directory of Open Access Journals (Sweden)

Alicia K. Morgans

2011-01-01

Full Text Available Male osteoporosis is an increasingly recognized problem in aging men. A common cause of male osteoporosis is hypogonadism. Thousands of men with prostate cancer are treated with androgen deprivation therapy, a treatment that dramatically reduces serum testosterone and causes severe hypogonadism. Men treated with androgen deprivation therapy experience a decline in bone mineral density and have an increased rate of fracture. This paper describes prostate cancer survivors as a model of hypogonadal osteoporosis and discusses the use of RANKL-targeted therapies in osteoporosis. Denosumab, the only RANKL-targeted therapy currently available, increases bone mineral density and decreases fracture rate in men with prostate cancer. Denosumab is also associated with delayed time to first skeletal-related event and an increase in bone metastasis-free survival in these men. It is reasonable to investigate the use of RANKL-targeted therapy in male osteoporosis in the general population.

Full Text Available In this study, it was aimed to investigate the relationship between diabetes and breast cancer and the detection of enzymes and ornithine levels in polyamine synthesis pathway in diabetes, breast cancer and diabetic breast cancer patients. Methods: Ornithine, arginine decarboxylase, ornithine decarboxylase and agmatinase levels have been measured in serum of all groups. Ornithine levels were measured spectrophotometrically. Arginine decarboxylase, ornithine decarboxylase and agmatinase levels were determined by ELISA kits. Results: Except for the diabetic group, the levels of enzymes in the polyamine synthesis pathway were increased in all and statistically significant (P < 0.05. The increase in the levels of agmatinase was very important among the enzymes (P < 0.001. Conclusions: Decreased levels of polyamine synthase enzymes in diabetes mellitus were found to be increased patients with breast cancer. Whether and how diabetes-based breast cancer development relates to increase activity of enzymes responsible for polyamine synthesis requires further mechanistic and prospective monitoring studies in larger patient cohorts.

Full Text Available OBJECTIVE: Chronic inflammation is considered as one of the contributing mechanisms of lower urinary tract symptoms (LUTS. Serum C-reactive protein (CRP level is the widely used biomarker of inflammatory status. This study investigated the association between serum CRP level in men with benign prostatic hyperplasia (BPH and lower urinary tract symptoms (LUTS before and after medical treatment. METHODS: A total of 853 men with BPH and LUTS were enrolled. All patients completed the International Prostate Symptoms Score (IPSS questionnaire and urological examinations. The parameters of uroflowmetry (maximum flow rate, Qmax; voided volume, VV, post-void residual (PVR, total prostate volume (TPV and transition zone index (TZI, serum prostate specific antigen (PSA, and serum CRP levels were obtained. All patients were treated with alpha-blocker or antimuscarinic agent based on the IPSS voiding to storage subscore ratio (IPSS-V/S. Correlation analyses were performed between serum CRP levels with age, IPSS, TPV, TZI, Qmax, PVR, VV, PSA and between baseline and post treatment. RESULTS: The mean age was 66.9 ± 11.6 years old and the mean serum CRP levels were 0.31 ± 0.43 mg/dL. Univariate analyses revealed serum CRP levels were significantly associated with age (p<0.001, PSA levels (p = 0.005 and VV (p = 0.017, but not significantly associated with TPV (p = 0.854 or PVR (p = 0.068. CRP levels were positively associated with urgency (p<0.001 and nocturia (p<0.001 subscore of IPSS, total IPSS (p = 0.008 and storage IPSS (p<0.001 and negatively associated with IPSS- V/S ratio (p = 0.014. Multivariate analyses revealed that serum CRP levels were significantly associated with age (p = 0.004 and storage IPSS subscore p<0.001. Patients with IPSS-V/S<1 and treated with tolterodine for 3 months had significant decrease of CRP levels after treatment. CONCLUSION: Serum CRP levels are associated with storage LUTS and sensory bladder disorders, suggesting chronic

Radioactive iodine (RAI) therapy and whole-body scanning are the fundamentals of treatment and follow-up of patients with differentiated thyroid cancer. It is generally accepted that a Thyroid-Stimulating Hormone (TSH) level of at least 30 {mu}U/ml is a prerequisite for the effective use of RAI, and that it requires 4-6 weeks of off-thyroxine to attain these levels. Because thyroxine withdrawal and the consequent hypothyroidism are often poorly tolerated, and occasionally might be hazardous, it is important to be certain that these assumptions are correct. We have measured serial changes in serum TSH after total thyroidectomy or withdrawl of thyroxine in patients with thyroid cancer. Serum TSH levels were measured weekly after thyroidectomy in 10 patients (group A) and after the discontinuation of thyroxine in 12 patients (group B). Symptoms and signs of hypothyroidism were also evaluated weekly by modified Billewicz diagnostic index. By the second week, 78% of group A patients and 17% of group B patients had serum TSH levels {>=} 30 {mu}U/ml. By the third week, 89% of group A patients and 90% of group B patients had serum TSH levels {>=} 30 {mu}U/ml. By the fourth week, all patients in two groups achieved target TSH levels and there were no overt hypothyroidism. In all patients, serum TSH elevated to the target concentration ({>=} 30 {mu}U/ml) within 4 weeks without significant manifestation of hypothyroidism. The schedule of RAI administration could be adjusted to fit. the needs and circumstances of individual patients with a shorter preparation period than the conventional.

Full Text Available Interleukin-(IL- 12 has been recently suggested to participate during development of insulin resistance in obese mice. Nevertheless, serum IL-12 levels have not been accurately determined in overweight and obese humans. We thus studied serum concentrations of IL-12 in Mexican adult individuals, examining their relationship with low-grade inflammation and obesity-related parameters. A total of 147 healthy individuals, 43 normal weight, 61 overweight, and 43 obese subjects participated in the study. Circulating levels of IL-12, tumor necrosis factor-alpha (TNF-α, leptin, insulin, glucose, total cholesterol, and triglyceride were measured after overnight fasting in all of the study subjects. Waist circumference and body fat percentage were recorded for all the participants. Serum IL-12 was significantly higher in overweight and obese individuals than in normal weight controls. Besides being strongly related with body mass index (r=0.5154, serum IL-12 exhibited a significant relationship with abdominal obesity (r=0.4481, body fat percentage (r=0.5625, serum glucose (r=0.3158, triglyceride (r=0.3714, and TNF-α (r=0.4717. Thus, serum levels of IL-12 are increased in overweight and obese individuals and show a strong relationship with markers of low-grade inflammation and obesity in the Mexican adult population. Further research is needed to understand the role of IL-12 in developing obesity-associated alterations in humans.

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

Serum ferritin is one of the markers indicating hemophagocytosis that may have a role in the pathogenesis of Crimean-Congo hemorrhagic fever (CCHF). This study was designed to determine any correlation between serum ferritin and routine diagnostic laboratory markers of CCHF, and to investigate the relationship between serum ferritin levels and disease severity. Sixty-six patients with CCHF admitted to the hospital during the spring and summer months of 2006 and 2007 were included in the study. Serum ferritin levels were measured in sera obtained during the initial days of hospitalization. Data from 53 patients showing decreasing platelet counts over the first three days were used for further analysis and these patients were divided into two groups according to disease severity: group A included severe cases with lowest platelet counts 20x10(9)/l. Forty patients (60.6%) were male (mean age 43+/-17 years). Three patients died, thus the fatality rate was 4.5%. Fifty-one patients (77.3%) had abnormal serum ferritin levels, with levels above 500 ng/ml in 62.1%. There was a significant negative correlation between ferritin levels and concordant platelet counts (p or =1862ng/ml had a sensitivity of 87.5% and a specificity of 83.8% in differentiating severe cases from mild ones. Increased serum ferritin levels may suggest a significant role of hemophagocytosis in the pathogenesis of CCHF and may be a useful marker for diagnosis, disease activity, and prognosis.

Serum amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) levels have been proposed as a biomarker of linear growth in healthy children. The usefulness of NT-proCNP in patients with achondroplasia (ACH)/hypochondroplasia (HCH) remains to be elucidated. The objective was to study whether serum NT-proCNP level is a good biomarker for growth in ACH/HCH and other patients of short stature. This was a longitudinal cohort study. Sixteen children with ACH (aged 0·4-4·3 years), six children with HCH (2·7-6·3 years), 23 children with idiopathic short stature (ISS) (2·2-9·0 years), eight short children with GH deficiency (GHD) (2·9-6·8 years) and five short children born small for gestational age (SGA) (2·0-6·6 years). Patients with ACH/HCH received GH treatment for 1 year. Serum NT-proCNP levels and height were measured. NT-proCNP levels positively correlated with height velocity in these short children (P < 0·05, r = 0·27). NT-proCNP levels inversely correlated with age in children with ISS alone (P < 0·01, r = -0·55). Serum NT-proCNP levels in patients with ACH/HCH were increased 3 months following the initiation of GH treatment (P < 0·05). Height SDS gain during GH treatment for 1 year was positively correlated with the changes in NT-proCNP levels after the initiation of GH (P < 0·01, r = 0·72). Serum NT-proCNP levels may be a good biomarker to indicate the effect of GH treatment on growth in patients with ACH/HCH at least in the first year and height velocity in short stature patients. © 2016 John Wiley & Sons Ltd.

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

Gender identity disorder (GID) results from a disagreement between a person's biological sex and the gender to which he or she identifies. With respect to the treatment of female to male GID, testosterone replacement therapy (TRT) is available. The uric acid (UA) level can be influenced by testosterone; however, the early effects and dose-dependency of TRT on the serum UA concentration have not been evaluated in this population. We herein conducted a dose-response analysis of TRT in 160 patients with female to male GID. The TRT consisted of three treatment groups who received intramuscular injections of testosterone enanthate: 125 mg every two weeks, 250 mg every three weeks and 250 mg every two weeks. Consequently, serum UA elevation was observed after three months of TRT and there was a tendency toward testosterone dose-dependency. The onset of hyperuricemia was more prevalent in the group who received the higher dose. We also demonstrated a positive correlation between increased levels of serum UA and serum creatinine. Since the level of serum creatinine represents an individual's muscle volume and the muscle is a major source of purine, which induces UA upregulation, the serum UA elevation observed during TRT is at least partially attributed to an increase in muscle mass. This is the first study showing an association between serum UA elevation and a TRT-induced increase in muscle mass. The current study provides important information regarding TRT for the follow-up and management of the serum UA levels in GID patients.

In management of AD, pharmacological treatment alone using acetylcholinesterase inhibitor (AChEI) is general consensus, and provides beneficial effect to prolong their progression. Combined non-pharmacological therapy, especially cognitive therapy is recently having attention with expectation of improvement in cognitive ability. This study examined the effect of combined cognitive therapy in AD patients who were maintaining AChEI using FDG PET. Four patients (689 yrs) who diagnosed as probable Alzheimer's disease based on the NINCDS-ADRDA criteria participated in this study. 12-week cognitive therapy comprised seven fields to enhance orientation, memory, recall, visuo-motor organization, categorization and behavior modification/sequencing. They received 45-minute sessions twice per week with maintaining their previous medication. Clinical improvement was assessed by comprehensive neuropsychological tests. Two FDG PET studies were performed before cognitive therapy and in the middle of the therapy, and compared to evaluate the effect of cognitive therapy to cerebral metabolism. Two of 4 patients whose initial cognitive impairment was milder had clinical improvement after 12 weeks, the rest who were more severely impaired failed to have clinical improvement. Regional cerebral hypometabolism on initial PET was correlated with their functional status. Follow up PET of two responders demonstrated the increases in regional metabolism in the temporal and/or frontal cortex, which was associated their functional improvement. Cerebral metabolism in poor responders were minimally increased or no changed. This preliminary data suggests that cognitive therapy is potentially useful to stabilize or improve cognitive and functional performance in AD patients with relatively mild cognitive dysfunction. And FDG PET could demonstrate possible candidates for cognitive therapy and the effect of the therapy

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

Graves’ disease (GD) is an organ-specific autoimmune disease, characterized by excessive autoantibody levels due to tolerance breakdown of thyroid-specific autoantigens. To determine the role of interleukin-17 (IL-17) and transforming growth factor-ß (TGF-β) in GD, we assessed their serum levels in patients with GD and healthy controls. Thirty patients with hyperthyroidism, goiter, and positive thyroid-stimulating hormone receptor antibody diagnosed as GD, according to the clinical diagnostic criteria for autoimmune thyroid disease. Blood samples were also from 30 healthy individuals matched for age and sex as a control. Serum levels of IL-17 and TGF-ß were by using ELISA. IL-17 and TGF-ß levels (14.43 ± 2.15 pg/mL and 10.44 ± 3.19 pg/mL, respectively) were significantly higher in patients with GD than in controls (7.07 ± 1.45 pg/mL and 4.95 ± 1.35 pg/mL, respectively). However, no correlation between IL-17 and TGF-β level in patients with GD. The elevated serum level of IL-17 and TGF-β in patients with GD reflects Th-2 predominance, which causes increasing of these pro-inflammatory cytokines.

Severe social withdrawal, called hikikomori, has drawn increased public attention. However, an optimal clinical approach and strategy of treatment has not been well established. Here, we report a case of hikikomori for which an exercise intervention using jogging therapy was effective, showing cerebral hemodynamic improvement. The patient was a 20 year old Japanese male who was hospitalized in order to evaluate and treat severe social withdrawal. Although depressive and anxiety symptoms partially subsided with sertraline alone, social withdrawal persisted due to a lack of self confidence. With his consent, we implemented exercise therapy with 30 minutes of jogging three times a week for three months. We did not change the pharmacotherapy, and his social withdrawal remarkably improved with continuous jogging exercise. Using near infrared spectroscopy to evaluate hemodynamic alteration, bilateral temporal hemodynamics considerably increased after the three-month jogging therapy. Regarding exercise therapy for mental illness, numerous studies have reported the effectiveness of exercise therapy for major depression. This case implied, however, that the applicability of exercise therapy is not limited to major depressive disorder. Jogging therapy may contribute to reinforcing self confidence associated with "resilience" in conjunction with neurophysiological modulation of neural networks.

Prostate cancer and radiation therapy--the message conveyed by serum prostate-specific antigen

Purpose: Prostate-specific antigen (PSA) is a powerful pretreatment prognosticator and a sensitive post-treatment outcome measure for clinically localized prostate cancer treated with radiation therapy. Today, the pretreatment serum PSA level appears to supersede both grade and T-stage as a determinant of outcome. This study was undertaken to attempt a reconciliation between the old (pre-PSA) and the new (PSA) data-in particular to address the question of why stage and grade apparently play so little role in this PSA era. Methods and Materials: We analyzed the outcome of two cohorts of men with T1-T4, N0, or NX, M0 prostate cancer, one group (648 patients) treated and followed in the pre-PSA era (1966-1988), another group (707 patients) treated and followed in the PSA era (1987-1993)--who received definitive radiation as their only initial treatment. The patterns of relapse and prognostic factors for these groups were compared and contrasted using univariate and multivariate techniques. Results: At a median follow-up of 6.5 years, the relapse patterns in the pre-PSA series were: local in 109 (17%), nodal in 17 (3%), and distant metastatic in 186 (29%). Actuarial local and metastatic rates at 5 years were 13 and 26%, respectively. Local recurrence was only weakly predictable, Gleason grade being the only significant, albeit weak, covariate. Metastatic failure, however, was highly significantly and meaningfully correlated with Gleason grade and T-stage. Because metastasis was the most common adverse end point in this series, overall freedom from progression also correlated with grade and stage. At a median follow-up of 31 months, the patterns of failure in the PSA series were: local in 77 (11%), nodal in 3 (< 1%), and distant metastatic in 24 (3%). Actuarial local and metastatic rates at 5 years were 30 and 6%, respectively. Local recurrence was highly and meaningfully correlated with pretreatment PSA level, which was the only significant determinant of this end

The κ/λ hybrid antibodies in normal human serum were reported recently, but their clinical relevance has not yet been explored. Rheumatoid arthritis (RA) is one of the major joint diseases, and the early diagnosis and treatment of RA remain a challenge. Here, we developed a double-sandwich enzyme-linked immunosorbent assay system to quantify relative serum κ/λ hybrid antibody levels in RA patients, osteoarthritis (OA) patients, and healthy controls (HC) in order to assess their potential use as a serological biomarker of early disease and clinical activity and to preliminarily investigate their immunomodulatory roles in RA. Surprisingly, we found that κ/λ hybrid antibody was markedly increased in both early and established RA. Serum κ/λ hybrid antibody levels were significantly correlated with clinical indexes and inflammatory markers in RA. Further analysis showed a positive correlation between κ/λ hybrid antibody levels and the 28-joint disease activity score (DAS28). In conclusion, serum κ/λ hybrid antibodies in RA were identified for the first time. High levels of κ/λ hybrid antibody may be a useful tool in distinguishing early RA from OA and HC. We suggest κ/λ hybrid antibody as a marker for disease activity. The increased κ/λ hybrid antibodies were associated with inflammatory conditions in RA.

States of growth hormone (GH) resistance, such those observed in Laron’s dwarf patients, are characterized by mutations in the GH receptor (GHR), decreased serum and tissue IGF-1 levels, impaired glucose tolerance, and impaired skeletal acquisition. IGF-1 replacement therapy in such patients increases growth velocity but does not normalize growth. Herein we combined the GH-resistant (GHR knockout, GHRKO) mouse model with mice expressing the hepatic Igf-1 transgene (HIT) to generate the GHRKO-HIT mouse model. In GHRKOHIT mice, serum IGF-1 levels were restored via transgenic expression of Igf-1 allowing us to study how endocrine IGF-1 affects growth, metabolic homeostasis, and skeletal integrity. We show that in a GH-resistant state, normalization of serum IGF-1 improved body adiposity and restored glucose tolerance but was insufficient to support normal skeletal growth, resulting in an osteopenic skeletal phenotype. The inability of serum IGF-1 to restore skeletal integrity in the total absence of GHR likely resulted from reduced skeletal Igf-1 gene expression, blunted GH-mediated effects on the skeleton that are independent of serum or tissue IGF-1, and from poor delivery of IGF-1 to the tissues. These findings are consistent with clinical data showing that IGF-I replacement therapy in patients with Laron’s syndrome does not achieve full skeletal growth. PMID:23456957

Full Text Available Objective　To evaluate the efficacy of nutrition therapy in alcoholic liver diseases (ALD. Methods　PubMed, Embase, Web of Science, The Cochrane Central Register of Controlled Trials, Chinese Journals Full-Text Database, Chinese Biomedical Database and Wan Fang Digital Journal Full-Text Database were searched for relevant articles. Statistical analysis was performed by meta-analysis using Review Manager 5.1.0. Results　Twelve randomized controlled trials including 508 cases were analyzed. Meta-analysis results were as follows: Compared with conventional therapy, nutrition therapy was more effective in reducing the serum total bilirubin (P=0.04 and alkaline phosphatase (P=0.04, and increasing serum transferrin (P＜0.00001, but there was no statistically significant difference between the two groups in other liver functions and complications associated with ALD. There was no statistically significant difference between the two groups in the incidence of infection, short-term or long-term mortality of ALD. Conclusions　Nutrition therapy can improve some important liver functions, such as serum total bilirubin, alkaline phosphatase, and transferrin in patients with ALD, but it may not improve the short-term or long-term mortality, other liver functions, or complications of ALD. Due to the above role in improving liver function, the nutrition therapy can be recommended as a routine treatment in patients with ALD. DOI: 10.11855/j.issn.0577-7402.2015.11.14

This study was to investigate the diagnostic value of serum procalcitonin(PCT) in identifying the etiology of non-responding community-acquired pneumonia (CAP) after initial antibiotic therapy. A retrospective analysis was performed for 232 hospitalized CAP patients admitted to the People's Hospital of Zhengzhou University during June 2013 and January 2014. Early treatment failure was defined as the presence of persistent fever (>38 °C) and/or clinical symptoms (malaise, cough, expectoration, dyspnea) or deterioration after at least 72 h of initial antimicrobial treatment, or development of respiratory failure requiring mechanical ventilation, or septic shock. Bronchoscopy or transthoracic lung biopsy was performed in case of early treatment failure when indicated. Serum level of PCT was detected by double antibody sandwich method. The differences between 2 or more groups were compared using 2-independent student t test, one-way ANOVA; Mann-Whitney U test, Kruskal-Wallis rank sum test, or χ(2) test. Risk factors and odds ratios for nonresponsiveness were analyzed by setting up a Logistic regression model. The diagnostic values of PCT were determined by receiver operating characteristic curves (ROC curves). Of the 232 CAP patients enrolled, 124 were male and 108 were female, with an average age of (46 ± 20) years. Thirty-six patients failed to respond to the initial antibiotic therapy. As shown by Logistic regression analysis, the risk factors for treatment failure included hypoalbuminemia, type 2 diabetes, previous history of splenectomy , PSI 4-5 grade, and lung infiltration ≥ 3 lobes. The most common causes of non-responsiveness were antimicrobial insufficiency (n = 23), and misdiagnosis of noninfectious mimics of pneumonia (n = 11), with 2 cases of unidentified etiology. The serum PCT level in admission was 0.19 (0.07-0.66) µg/L in the antimicrobial insufficiency subgroup, which was significantly higher than that in the misdiagnosis subgroup [0

Despite vitamin A supplementation programs, vitamin A deficiency in children remains a public health concern in Honduras. We investigated the effectiveness of short-term dietary supplementation of mothers with red palm oil as a strategy for improving the vitamin A status of the mother-infant dyad. Lactating mothers in Colonia Los Pinos, a barrio of Tegucigalpa, Honduras, consumed a total of 90-mg beta-carotene as red palm oil (n = 32) supplements (n = 36) or placebo (n = 18) in six equal doses over 10 days. Carotenoids and retinol in maternal and infant serum, and breastmilk carotenoids and retinol were measured before and after supplementation. Maternal diet was evaluated by 24-hour recall. Maternal serum alpha-carotene and beta-carotene concentrations were increased 2 fold by palm oil compared with 1.2 fold by beta-carotene supplements. Changes were significantly different in infant serum alpha-carotene but not beta-carotene among the three experimental groups. Increases in breastmilk beta-carotene were greater for the palm oil group (2.5 fold) than for the beta-carotene supplement group (1.6 fold) and increases in milk alpha-carotene concentrations (3.2 fold) were slightly greater than those of beta-carotene. There were also small but significant changes among groups in breastmilk lutein and lycopene. Breastmilk retinol was not significantly different among the groups over the treatment period. Red palm oil in the maternal diet increases provitamin A carotenoids in breastmilk and serum of the mother-infant dyad. The use of dietary red palm oil to improve the vitamin A status of this population should be further investigated.

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

To evaluate the serum levels of zonulin, which regulates tight junctions between enterocytes and is a physiological modulator controlling intestinal permeability, in patients with autism spectrum disorders (ASDs). Serum zonulin levels were determined in 32 patients with ASD and 33 healthy controls using an enzyme-linked immunosorbent assay. The severity of ASD symptoms was assessed with the Childhood Autism Rating Scale. Serum zonulin levels were significantly higher in the patients with ASD (122.3 ± 98.46 ng/mL) compared with the healthy controls (41.89 ± 45.83 ng/mL). There was a positive correlation between zonulin levels and Childhood Autism Rating Scale score when all subjects were assessed (r = 0.523; P zonulin, which regulates intestinal permeability, plays a role in the development of symptoms of ASD.

To compare serum lipid profile between patients of ischaemic and haemorrhagic strokes. Study Design: Cross sectional, comparative study. Place and Duration of Study: Military Hospital, Rawalpindi, from August 2004 to February 2005. Methodology: Patients with diagnosis of stroke comprising 100 consecutive patients each of ischaemic and haemorrhagic strokes were included in the study while patients on lipid lowering therapy were excluded from study. To determine the subtype of stroke, clinical examination followed by CT scan of brain was done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. Statistical analysis was done by comparison of lipid profile in two subgroups, using proportion test for any significant difference. Results: The mean age at presentation of patients with stroke was 64.2+-12 years with a male to female ratio of 3.6:1. In 100 ischaemic stroke patients, raised serum total cholesterol was seen in 42, triglyceride in 04, LDL-cholesterol in 05 and VLDL-cholesterol in 07 patients. Serum HDL-cholesterol was below the normal reference in 31 cases. On the other hand, serum total cholesterol and triglycerides was raised in 05 patients each, LDL-cholesterol in 09 and VLDL-cholesterol in 03 patients of haemorrhagic stroke. Serum HDL-cholesterol was below normal in 04 patients of haemorrhagic stroke. On comparison, there were significantly greater number of patients with raised serum cholesterol and low HDL-cholesterol in ischaemic stroke than haemorrhagic stroke (p < 0.05). No statistical significance was found on comparing serum values of ischaemic and haemorrhagic stroke for triglycerides, LDL-cholesterol and VLDL-cholesterol. Conclusion: Ischaemic stroke patients had high serum total cholesterol and lower HDL-cholesterol levels as compared to

Objective: To investigate the application value of urine brain natriuretic peptide (BNP) level in 131 I treatment of hyperthyroid heart disease. Methods: One hundred and eleven hyperthyroidism patients who received 131 I therapy were divided into two groups, hyperthyroidism group (51 cases) and hyperthyroid heart disease group (60 cases), and 30 healthy subjects as control. Sixty patients in the hyperthyroid heart disease group all received ultrasonic cardiogram. The hyperthyroid heart disease group was divided into two subgroups according to New York Heart Association (NYHA) functional classification (hyperthyroid heart disease A subgroup and hyperthyroid heart disease B subgroup). The urine and serum BNP level and serum free triiodothyronine (FT 3 ), free thyroxine (FT 4 ) level were measured through chemiluminescence before and after therapy. Results: The urine and serum BNP level before 131 I therapy of the hyperthyroid heart disease group were significantly higher than those of hyperthyroidism group (serum: t=8.98 and 9.52, both P<0.01; urine: t=10.83 and 12.73, both P<0.01) and the control group (serum: t=8.97 and 9.52, both P<0.01; urine: t=9.21 and 5.64, both P<0.01). The urine and serum BNP level before and 6, 12 months after 131 I therapy of the hyperthyroid heart disease A subgroup were significantly higher than those of hyperthyroid heart disease B subgroup (serum: t=5.98, 5.87 and 6.35, all P<0.01; serum: t=4.33, 4.09 and 5.02, all P<0.01). The urine level of BNP was gradually increased with the severity of cardiac insufficiency and it was positively correlated with the serum level of BNP (r=0.829, P<0.01), the NYHA functional classification (r=0.751, P<0.01) and the serum level of FT 3 and FT 4 (FT 3 : r=0.635, P<0.01; FT 4 : r=0.672, P<0.01). Conclusions: The urine BNP level of hyperthyroid heart disease patient increased with the severity of cardiac insufficiency. The urine BNP level could accurately reflect cardiac function of hyperthyroid heart

Full Text Available Background. Recent studies confirmed cardioprotective role of intravenous magnesium for the prevention of cardiac events, but effect of dietary intake of this mineral via recommended dietary regimens on control and inhibition of coronary artery disease (CAD risk factors has been questioned. The aim of the present study was to determine effect of Mediterranean dietary approach on serum magnesium concentration among Iranian patients with CAD. Method. Baseline characteristics and clinical data of 102 consecutive patients with the diagnosis of CAD and candidates for isolated coronary artery bypass surgery were entered into the study. Laboratory parameters especially serum magnesium concentration were measured after 12–14 h of overnight fasting and before operation. Nutritional status was assessed by food frequency questionnaire and the diet score was calculated on the basis of Mediterranean diet quality index (Med-DQI. Results. No significant differences were found in the concentrations of albumin, last fasting blood sugar, last creatinine, and lipid profiles between the groups with Mediterranean dietary score < 5 and the group with higher dietary score; however, serum magnesium concentration in the first group was higher than that in the group with higher dietary score. Linear multivariate regression analysis showed that the lower Mediterranean dietary score was a predictor for serum magnesium concentration after adjusting for confounders. Conclusion. Taking Mediterranean dietary regimen can be associated with increased level of serum magnesium concentration, and thus this regimen can be cardioprotective because of its effects on serum magnesium.

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

The Bruton's tyrosine kinase inhibitor ibrutinib is a highly effective, new targeted therapy for chronic lymphocytic leukemia (CLL) that thwarts leukemia cell survival, growth, and tissue homing. The effects of ibrutinib treatment on the T cell compartment, which is clonally expanded and thought to support the growth of malignant B cells in CLL, are not fully characterized. Using next-generation sequencing technology, we characterized the diversity of TCRβ-chains in peripheral blood T cells from 15 CLL patients before and after 1 y of ibrutinib therapy. We noted elevated CD4 + and CD8 + T cell numbers and a restricted TCRβ repertoire in all pretreatment samples. After 1 y of ibrutinib therapy, elevated peripheral blood T cell numbers and T cell-related cytokine levels had normalized, and T cell repertoire diversity increased significantly. Dominant TCRβ clones in pretreatment samples declined or became undetectable, and the number of productive unique clones increased significantly during ibrutinib therapy, with the emergence of large numbers of low-frequency TCRβ clones. Importantly, broader TCR repertoire diversity was associated with clinical efficacy and lower rates of infections during ibrutinib therapy. These data demonstrate that ibrutinib therapy increases diversification of the T cell compartment in CLL patients, which contributes to cellular immune reconstitution.

The use of a growth hormone (GH) receptor antagonist, pegvisomant has shown great promise in adults with acromegaly, but experience in paediatric patients is lacking. We aimed to describe the results of pegvisomant therapy in a 12-year-old girl with an aggressive GH-secreting pituitary tumour. To evaluate the ability of pegvisomant therapy to control the effects of peripheral GH excess in a case of pituitary gigantism. Pegvisomant was introduced at 10 mg/day, given subcutaneously, and gradually increased to 20 mg/day until serum IGF-I was normal for age. A large pituitary adenoma with suprasellar extension was diagnosed in a 12-year-old girl with progressive tall stature (178 cm), GH hypersecretion without suppression during oral glucose loading (nadir serum GH, 90 mU/l), high serum IGF-I and serum prolactin levels. Surgical extirpation was not possible because tumour tissue was fibrous and adherent to the optical nerves. Histological examination showed a mixed GH- and prolactin-secreting adenoma with lymphocytic infiltration of B and T cells. Treatment with a dopamine agonist, cabergoline, normalized serum prolactin, but GH secretion was resistant to both somatostatin analogue, octreotide and cabergoline. Radiation followed by pegvisomant therapy titrated up in dose to 20 mg/day led to a marked reduction in GH secretion and normalization of IGF-I, and to growth arrest and improvement of well-being. We suggest that treatment in pituitary gigantism with pegvisomant is safe and may normalize IGF-I levels and effectively stop growing.

The tested quality signs of the digoxin-RIA (Medica) correspond to other RIA-test methods. The digoxin-RIA (Medica) is, therefore, well suited for clinical examinations. In the dilanacin-(digoxin-) long-term therapy with the maintenance dose of 0.5 mg digoxin a day 75.4% of the patients examined (n = 65) were within the therapeutic field. In each case 12.3% were underdigitalised or overdigitalised, respectively. In the 8 patients in the toxic region only the half showed signs of digoxin intoxication. It is referred to the importance of creatinine and potassium in the serum, to the digoxin creatinene and potassium in the serum, to the digoxin clearance depending on age, to the body weight and the body surface, respectively, in very obese patients for the height of the serum digoxin level and for the compatibility of this heart glycoside.

Human serum paraoxonase contributes to the anti-atherogenic effect of high-density lipoprotein cholesterol (HDL-C) and has been shown to protect both low-density lipoprotein cholesterol (LDL-C) and HDL-C against lipid peroxidation. We investigated the effects of rosiglitazone on paraoxonase activity and metabolic parameters in patients with type 2 diabetes mellitus [50 patients (30 males, 20 females); mean±SD age: 58.7±9.2 years, body mass index: 28.2±4.1'kg/m{sup 2}], in whom glucose control could not be achieved despite treatment with metformin, sulphonylurea, and/or insulin. The patients were given 4'mg/day rosiglitazone for 3 months in addition to their usual treatment. Serum paraoxonase activity, malondialdehyde, homocysteine, and lipid profile were measured at the time of initiation and at the end of therapy with rosiglitazone. After rosiglitazone therapy, serum levels of HDL-C, apolipoprotein A-1, and paraoxonase activity increased significantly (P<0.05) and malondialdehyde, homocysteine, lipoprotein(a), and glucose levels decreased significantly (P<0.05), but no significant changes in levels of total cholesterol and apolipoprotein B were observed. Triglyceride levels also increased significantly (P<0.05). Rosiglitazone treatment led to an improvement in glycemic control and to an increase in paraoxonase activity and HDL-C levels. Although rosiglitazone showed favorable effects on oxidant/antioxidant balance and lipid profile, further studies are needed to determine the effect of rosiglitazone on cardiovascular risk factors and cardiovascular morbidity and mortality.

To comprehensively and exhaustively assess the relationship between serum ferritin levels and incidence of prediabetes in a prospective study. This prospective cohort study (n=7380) with a mean follow-up of 3.07 years (range: 1-7, 95% CI: 3.03-3.12) was conducted in Tianjin, China. Blood fasting glucose, oral glucose tolerance test, serum ferritin levels and other potentially confounding factors were measured at baseline and at each year of follow-up. Adjusted Cox proportional hazards regression models were used to assess the gender-specific relationship between baseline and mean serum ferritin quintiles and prediabetes. The incidence of prediabetes was 85 per 1000 person-years among men and 44 per 1000 person-years among women during follow-up (from 2007 to 2014). After adjusting for potential confounders, hazard ratios (95% CI) for prediabetes across baseline ferritin quintiles were: for men, 1.00, 1.13 (0.90-1.40), 1.20 (0.97-1.48), 1.41 (1.14-1.73) and 1.73 (1.41-2.11); and for women, 1.00, 1.01 (0.74-1.38), 0.68 (0.48-0.96), 0.84 (0.61-1.15) and 1.07 (0.80-1.45), respectively. Similar results were also observed for mean ferritin levels. Both baseline and mean serum ferritin levels were significantly and linearly related to prediabetes in men, whereas U-shaped relationships were observed between baseline and mean serum ferritin and prediabetes in women. The relationship between prediabetes risk and mean serum ferritin levels may be more stable than one with baseline serum ferritin levels. Copyright © 2016. Published by Elsevier Masson SAS.

Full Text Available Background Suppressive doses of levothyroxine therapy are reported to reduce bone mineral density (BMD in women. Data on bone changes in premenopausal hypothyroid women with replacement therapy are limited. Hence, this study was undertaken to evaluate bone changes in this group using bone markers and BMD. Materials and Methods A hospital-based case–control study including 75 premenopausal women aged 30–45 years was conducted. The subjects were categorized based on their thyroid function and history into three groups of 25 euthyroid, 25 newly diagnosed hypothyroid, and 25 hypothyroid women on 100–200 μg of levothyroxine for a minimum of 5 years. The bone changes were evaluated and compared among the groups biochemically by estimating their plasma osteocalcin and serum calcium and phosphorus and radiologically by measuring their BMD by quantitative ultrasonography. Statistical analysis was conducted by using analysis of variance, Tukey's test, and Pearson's correlation using IBM SPSS Statistics 20. Results Levels of plasma osteocalcin, serum calcium, and serum phosphorus in patients on long-term levothyroxine therapy were significantly higher than those in newly diagnosed hypothyroid women and in the euthyroid group. BMD showed definite features of osteopenia ( T -score: −2.26 ± 0.5 among the women in the treatment group, while it was well within the normal range in the newly diagnosed and euthyroid women. A significant correlation was found between the osteocalcin levels and T -score. Conclusion Hypothyroid women on long-term levothyroxine therapy showed signs of increased bone turnover and increased resorptive changes, though not frank osteoporosis. Hence, it may be important to evaluate the bone status of patients on levothyroxine for >5 years.

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

To determine the frequency of increase in serum tumor marker CEA levels in PBC patients at the time of diagnosis. Study Design: Cross sectional study. Place and Duration of Study: Oncology Department of Combined Military Hospital (CMH) Rawalpindi, from January 2014 to November 2014. Material and Methods: Sixty three female patients with histopathologically confirmed carcinoma of breast and age range from 20 to 70 years from Oncology outpatient department (OPD)/indoor patient department at CMH Rawalpindi, were selected. All patients were staged by clinical and radiological work-up that included physical examination, all base line investigations, serum biomarkers, chest radiograph, ultrasound abdomen and pelvis, bone scan, computed tomography (CT) scan/magnetic resonance imaging (MRI) of the chest (optional). Patients serum carcino-embryonic antigen (CEA) levels were carried out only by blood sampling using chemiluminescent immunoassay with immulite 2000 CEA. Data analysis were done with the help of the Statistical Package for the Social Sciences (SPSS) version 19 software. Cut-off values of serum CEA levels >2.5 ng/ml were taken as elevated. Results: Sixty three female breast cancer patients with histopathologically confirmed carcinoma of breast revealed elevated serum CEA levels in three stages of the disease. The median age was 47 years (range, 20-70 years). Fifteen (23.8%) patients had family history of the breast cancer. Invasive ductal carcinoma (IDCA) was the commonest histology with 60 (95.23%) patients. Most of the patients had advanced stage of the disease. Node positive cases were 53 (84.1%). The frequency of abnormal CEA levels were varying from stage II to stage IV. Elevated serum CEA levels were noted in 4 (28.6%) of stage II, 19 (76%) of stage III and 17 (77.3%) patients of stage IV, respectively. Overall percentage increase in levels of serum CEA from stage I through IV were 0%, 6.34%, 30.2%, 26% respectively. The sensitivity of serum CEA in our

Full Text Available Abstract Malnutrition, anemia and increased atherosclerosis are the main causes of mortality in hemodialysis patients. Therapies designed to improve the disorders might therefore be expected to improve outcome. The effects of Nandrolone Decanoate (ND, in 64 stable hemodialysis patients, were studied with respect to the following parameters: nutritional status, hematological indexes, lipid profiles including serum levels of lipoprotein(a [Lp(a] in terms of differences in apolipoprotein(a [apo(a]. The patients were treated with ND at dose of 100 mg/I.M./week for 4 months. After 2 and 4 months of treatment the elevations in the serum levels of albumin (p 30 mg/dl than those of with low Lp(a (

Full Text Available The κ/λ hybrid antibodies in normal human serum were reported recently, but their clinical relevance has not yet been explored. Rheumatoid arthritis (RA is one of the major joint diseases, and the early diagnosis and treatment of RA remain a challenge. Here, we developed a double-sandwich enzyme-linked immunosorbent assay system to quantify relative serum κ/λ hybrid antibody levels in RA patients, osteoarthritis (OA patients, and healthy controls (HC in order to assess their potential use as a serological biomarker of early disease and clinical activity and to preliminarily investigate their immunomodulatory roles in RA. Surprisingly, we found that κ/λ hybrid antibody was markedly increased in both early and established RA. Serum κ/λ hybrid antibody levels were significantly correlated with clinical indexes and inflammatory markers in RA. Further analysis showed a positive correlation between κ/λ hybrid antibody levels and the 28-joint disease activity score (DAS28. In conclusion, serum κ/λ hybrid antibodies in RA were identified for the first time. High levels of κ/λ hybrid antibody may be a useful tool in distinguishing early RA from OA and HC. We suggest κ/λ hybrid antibody as a marker for disease activity. The increased κ/λ hybrid antibodies were associated with inflammatory conditions in RA.

The measurement of serum free light chain (sFLC) has been shown to be valuable in screening for the presence of plasma cell dyscrasia as well as for baseline prognosis in newly diagnosed patients. The aim of the present work was to study the prognostic value of sFLC in multiple myeloma in relation to other serum biomarkers, response to therapy and survival. Forty five newly diagnosed patients with MM were included in the study. Patients were divided into responders and non-responders groups according to response to therapy. sFLC and serum Amyloid A (SAA) were measured by immunonephelometry. The non-responders group showed a statistically significant higher kappa/lambda or lambda/kappa ratio and higher β2 microglobulin level, but lower albumin level at presentation, as compared to the responders group (P < 0.001). However, no statistically significant difference was detected between the two groups regarding SA A or calcium levels. Comparison between sFLC ratio obtained before and after therapy revealed significant decrease after treatment in the responders group (P = 0.05). Survival was significantly inferior in patients with an FLC ratio of ≥ 2.6 or ≤ 0.56 compared with those with an FLC ratio that was between 0.56 and 2.6 (P = 0.002).

Ovarian cancer is the most lethal malignancy among gynaecological cancers. Although many anticancer agents have been developed for the treatment of ovarian cancer, it continues to have an extremely poor prognosis. Heparin-binding epidermal growth factor-like grown factor (HB-EGF) has been reported to be a rational therapeutic target for ovarian cancer. Here, we evaluated the clinical significance of serum HB-EGF by examining the association between prognosis and serum HB-EGF levels in patients with primary ovarian cancer. We found that high serum HB-EGF concentrations were significantly associated with poor prognosis in a combined cohort of patients with all stages of ovarian cancer, as well as in a subset of patients with advanced disease. In addition, serum HB-EGF levels increased as the cancer advanced. These data suggest that serum HB-EGF may be a target for the design of novel therapies for ovarian cancer.

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

A report of a 48 year-old male with non-Hodgkin's lymphoma of the left parotid gland (clinical stage I EA, follicular medium-sized B cell type) is presented. He was solely treated with 30 Gy of radiation to the whole neck region, bilateral paraclavicular region and the left axilla, and 10.6 Gy boost was given to the primary lesion. Five months later, facial edema and serum LDH elevation developed suddenly. Relapse of the malignant lymphoma was suspected, but a whole body CT scan failed to show this. On the contrary, the CT scan showed a diffuse hypoattenuated area of the thyroid gland. In addition to positive antibodies, i.e, antithyroglobulin and antimicrosomal antibodies, total cholesterol and other serum markers also suggested hypofunction of the thyroid due to acute exacerbation of chronic thyroiditis. Immediately after hormone-replacement therapy, his symptoms disappeared and the abnormal serum data improved. Although the relationship between chronic thyroiditis and radiation injury has not been clearly demonstrated, it seems necessary to evaluate thyroid function before radiotherapy for head and neck tumors. Patients with chronic thyroiditis should be followed carefully after radiotherapy. (author)

Serum prostate specific antigen (PSA) concentrations lack the specificity to differentiate prostate cancer from benign prostate hyperplasia (BPH), resulting in unnecessary biopsies. We identified 5 autoantibody signatures to specific cancer targets which might be able to differentiate prostate cancer from BPH in patients with increased serum PSA. To identify autoantibody signatures as biomarkers, a native antigen reverse capture microarray platform was used. Briefly, well-characterized monoclonal antibodies were arrayed onto nanoparticle slides to capture native antigens from prostate cancer cells. Prostate cancer patient serum samples (n=41) and BPH patient samples (collected starting at the time of initial diagnosis) with a mean follow-up of 6.56 y without the diagnosis of cancer (n=39) were obtained. One hundred micrograms of IgGs were purified and labeled with a Cy3 dye and incubated on the arrays. The arrays were scanned for fluorescence and the intensity was quantified. Receiver operating characteristic curves were produced and the area under the curve (AUC) was determined. Using our microarray platform, we identified autoantibody signatures capable of distinguishing between prostate cancer and BPH. The top 5 autoantibody signatures were TARDBP, TLN1, PARK7, LEDGF/PSIP1, and CALD1. Combining these signatures resulted in an AUC of 0.95 (sensitivity of 95% at 80% specificity) compared to AUC of 0.5 for serum concentration PSA (sensitivity of 12.2% at 80% specificity). Our preliminary results showed that we were able to identify specific autoantibody signatures that can differentiate prostate cancer from BPH, and may result in the reduction of unnecessary biopsies in patients with increased serum PSA.

Amiodarone is an amphiphilic, iodinated, benzofuran derivative that is known to be effective for refractory ventricular tachyarrhythmia. Amiodarone also is known to cause a variety of side effects, related to its accumulation in multiple organs. The deposition of amiodarone and its metabolite, desethylamiodarone (DA), in liver elevates liver function tests and increases liver attenuation on computed tomography (CT). Although several groups have reported increased liver attenuation in patients receiving chronic amiodarone therapy, there is still no clear statistically significant relationship between liver CT attenuation and the cumulative dose of amiodarone, or between plasma levels of amiodarone and DA. CT scans were originally performed for the evaluation of pulmonary fibrosis in 13 patients (7 men and 6 women; mean age, 69.9 years, range 35 to 86 years) receiving chronic amiodarone therapy. Liver CT attenuation tended to increase in these patients. We found no significant correlation between liver CT attenuation and the cumulative dose of amiodarone. However, the CT attenuation of the liver was correlated significantly with the plasma level of amiodarone and DA. It was also suggested that liver CT scan is a useful means of evaluating the plasma levels of amiodarone and DA, and for estimating their deposition in liver. (author)

Magnesium, which is an essential trace element that plays a key role in several cellular processes, is a major component of bone; however, its relationship with risk of major bone fractures is uncertain. We aimed to investigate the association of baseline serum magnesium concentrations with risk of incident fractures. We analyzed data on 2245 men aged 42-61 years in the Kuopio Ischemic Heart Disease prospective cohort study, with the assessment of serum magnesium measurements and dietary intakes made at baseline. Hazard ratios [95% confidence intervals (CI)] for incident total (femoral, humeral, and forearm) and femoral fractures were assessed. During a median follow-up of 25.6 years, 123 total fractures were recorded. Serum magnesium was non-linearly associated with risk of total fractures. In age-adjusted Cox regression analysis, the hazard ratio (HR) (95% CIs) for total fractures in a comparison of the bottom quartile versus top quartile of magnesium concentrations was 2.10 (1.30-3.41), which persisted on adjustment for several established risk factors 1.99 (1.23-3.24). The association remained consistent on further adjustment for renal function, socioeconomic status, total energy intake, and several trace elements 1.80 (1.10-2.94). The corresponding adjusted HRs for femoral fractures were 2.56 (1.38-4.76), 2.43 (1.30-4.53) and 2.13 (1.13-3.99) respectively. There was no evidence of an association of dietary magnesium intake with risk of any fractures. In middle-aged Caucasian men, low serum magnesium is strongly and independently associated with an increased risk of fractures. Further research is needed to assess the potential relevance of serum magnesium in the prevention of fractures.

Docosahexaenoic acid (DHA) is considered to be important for cardiac and brain function, and 17β-estradiol (E2) appears to increase the conversion of α-linolenic acid (ALA) into DHA. However, the effect of varying ALA intake on the positive effect of E2 on DHA synthesis is not known. Therefore, the objective of this study was to investigate the effects of E2 supplementation on tissue and serum fatty acids in mice fed a low-ALA corn oil-based diet (CO, providing 0.6 % fatty acids as ALA) or a high ALA flaxseed meal-based diet (FS, providing 11.2 % ALA). Ovariectomized mice were implanted with a slow-release E2 pellet at 3 weeks of age and half the mice had the pellet removed at 7 weeks of age. Mice were then randomized onto either the CO or FS diet. After 4 weeks, the DHA concentration was measured in serum, liver and brain. A significant main effect of E2 was found for liver and serum DHA, corresponding to 25 and 15 % higher DHA in livers of CO and FS rats, respectively, and 19 and 13 % in serum of CO and FS rats, respectively, compared to unsupplemented mice. There was no effect of E2 on brain DHA. E2 results in higher DHA in serum and liver, at both levels of dietary ALA investigated presently, suggesting that higher ALA intake may result in higher DHA in individuals with higher E2 status.

Combination of several drugs is often necessary especially during long-term therapy. The competitive binding drugs can cause a decrease in the amount of drug bound to protein and increase the biological active fraction of the drug. The aim of this study is to analyze the interactions of Lomefloxacin (LMF) and Colchicine (COL) with human serum albumin (HSA) and to evaluate the mechanism of simultaneous binding of LMF and COL to protein. Fluorescence analysis was used to estimate the effect of drugs on the protein fluorescence and to define the binding and quenching properties of drugs-HSA complexes. The binding sites for LMF and COL were identified in tertiary structure of HSA with the use of spectrofluorescence analysis. The analysis of fluorescence quenching of HSA in the binary and ternary systems show that LMF does not affect the complex formed between COL and HSA. On the contrary, COL decreases the interaction between LMF and HSA. The results of synchronous fluorescence, resonance light scattering and circular dichroism spectra of binary and ternary systems show that binding of LMF and COL to HSA can induce micro-environmental and conformational changes in HSA. The simultaneous presence of LMF and COL in binding to HSA should be taken into account in the multi-drug therapy, and necessity of using a monitoring therapy owning to the possible increase of the uncontrolled toxic effects. Molecular modeling of the possible binding sites of LMF and COL in binary and ternary systems to HSA confirms the spectroscopic results.

Obesity is a risk factor for postmenopausal breast cancer and is associated with poor prognosis. Leptin and adiponectin are cytokines synthesized in adipose tissue and have been implicated as a link between obesity and breast cancer. Therefore, in this study we analyzed and compared: serum leptin, adiponectin, lipid profile including cholesterol, triglycerides (TG), high density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) and body mass index (BMI) in breast cancer patients before and after Post Mastectomy Radio- therapy (PMRT).Serum leptin and adiponectin significantly increased and decreased respectively in patients after PMRT compared to the controls. BMI statistically decreased after radiotherapy while LDL-c increased in breast cancer patients; in both patients groups. HDL-c was statistically decreased but triglycerides showed significant increase in breast cancer patients. These results denoted that dyslipidemia may be associated with breast cancer risk and the evaluation of leptin and adiponectin can be used for follow up of patients under radiotherapy treatment for breast cancer

Full Text Available This study investigated some immunological features by experimental periodontitis (EP and rheumatoid arthritis (RA disease interact in destructive processes in arthritic rats. Rats were assigned to the following groups: EP +RA; RA; EP; and Negative Control. RA was induced by immunizations with type-II collagen and a local immunization with Complete Freund's adjuvant in the paw. Periodontitis was induced by ligating the right first molars. The serum level of rheumatoid factor (RF and anti-citrullinated protein antibody (ACCPA were measured before the induction of EP (T1 and at 28 days after (T2 by ELISA assay. ACCPA levels were also measured in the gingival tissue at T2. The specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for the quantification of interleukin IL-1β, IL-4, IL-6, IL-17 and TNF-α using a Luminex/MAGpix assay. Paw edema was analyzed using a plethysmometer. Periodontitis increased the RF and ACCPA levels in the serum and in the gingival tissue, respectively. Besides, the level of paw swelling was increased by EP and remained in progress until the end of the experiment, when EP was associated with RA. Greater values of IL-17 were observed only when RA was present, in spite of PE. It can be concluded that periodontitis increases rheumatic factor serum levels and citrullinated proteins level in gingival tissues and alter cytokine balance in arthritic rats; at the same time, arthritis increases periodontal destruction, confirming the bidirectional interaction between diseases.

Serum trace elements were analyzed by particle induced X-ray emission (PIXE) method in a patient with acute aortic dissection during the supportive process by a Nutrition support team (NST). The patient was a 53-year old male who suffered from acute aortic dissection on March 1, 2007. He received emergent Bentall operation and bow pars total displacement. Since he suffered from diarrhea as a result of hypoalbuminemia and bowel dysfunction, enteral nutrition was not sufficient to maintain adequate intake. Therefore, we also used parenteral nutrition until the 97th disease day. Afterwards, the patient managed only with enteral nutrition. We measured serum trace elements during these periods. Serum trace elements such as Fe, Zn and Se were preserved within normal ranges. On the other hand, Cu gradually decreased until the 54th disease day (44 μg/l) and stayed in the lower levels around the detection limit until the 109th disease day. Thereafter, Cu slightly increased and reached 117 μg/l on the 131st disease day (reference range of serum Cu in adult males: 700-1,300 μg/l). It was suggested that the serum levels of these trace elements might reflect the nutritional stages of the patient and could be useful as clinical markers for nutritional therapies. (author)

HIV and antiretroviral therapy: lipid abnormalities and associated cardiovascular risk in HIV-infected patients.

Kotler, Donald P

2008-09-01

It has been demonstrated that patients on highly active antiretroviral therapy are at increased risk for developing metabolic abnormalities that include elevated levels of serum triglycerides and low-density lipoprotein cholesterol and reduced levels of high-density lipoprotein cholesterol. This dyslipidemia is similar to that seen in the metabolic syndrome, raising the concern that highly active antiretroviral therapy also potentially increases the risk for cardiovascular complications. This paper reviews the contribution of both HIV infection and the different components of highly active antiretroviral therapy to dyslipidemia and the role of these abnormalities toward increasing the risk of cardiovascular disease in HIV-infected patients; therapeutic strategies to manage these risks are also considered.

In cetaceans, diving behavior immediately induces a change in blood circulation to favor flow to the brain and heart; this is achieved by intense vasoconstriction of the blood vessels that serve other organs. This blood circulation response is allied to a decrease in heart rate in order to optimize oxygen usage during diving. Vasoconstrictors are present in all mammals and stimulate the contraction of the smooth muscle in the walls of blood vessels. The most important of these vasoconstrictors are the hormones adrenaline (A), noradrenaline (NA), and angiotensin II (ANG II). At present, the contribution of these hormones to vasoconstriction during diving in cetaceans is unclear. To elucidate their possible roles, changes in serum levels of A, NA and ANG II were monitored together with heart rate in the Indo-Pacific bottlenose dolphin Tursiops aduncus during 90 and 180s dives. Both brief diving periods induced an increase in serum NA concentration and a decrease in heart rate; however, no changes were detected in serum levels of A or ANG II. These data indicate that NA may play a role in diving-induced vasoconstriction. Copyright © 2017 Elsevier Inc. All rights reserved.

The determination of serum myeloid-related protein MRP 8/14 (calprotectin) in Armenian patients with FMF before and after treatment with colchicine (including colchicine-resistant patients who don't respond to 2 mg of colchicine; t patients who don't respond to 1,5 mg of colchicine, and also responders to different dose of colchicine) and estimation of the response to antiinflammatory therapy. MRP 8/14 serum levels were measured in 80 FMF patients before and after treatment with colchicine and in healthy individuals (n = 11) and patients with rheumatoid arthritis RA (n=11) as a control group. Serum MRP 8/14 concentration was measured by ELISA (Enzyme Linked-Immuno-Sorbent-Assay) method using "Buhlmann" kit (Switzerland) in the laboratory with modern equipment. Serum MRP 8/14 concentrations were within a normal ranges in healthy individuals and elevated in patients with FMF and RA. MRP 8/14 serum levels in FMF patients were higher than in RA patients. Serum MRP 8/14 concentrations in FMF patients before colchicines therapy were higher than after treatment. The findings of our study indicate that myeloid-related protein MRP 8/14 is a very sensitive marker of the disease activity and response to antiinflammatory therapy in FMF.

Full Text Available BACKGROUND: Neopterin is a soluble biomarker of monocyte activation and its increased concentration might be expressed in atherosclerosis. Until recently, there has been lacking of information on the prognostic role of neopterin in acute coronary syndromes (ACS. The study was aimed at measuring the associations between elevated serum neopterin and increased risk of cardiovascular (CV events in ACS. METHODS: This was a prospective cohort study, recruited 71 ACS patients from January 31 through August 31, 2007 in Sanglah Hospital of Udayana School of Medicine, Denpasar, Bali. Cardiovascular events, such as: CV death, recurrent myocardial infarction, stroke and recurrent myocardial ischemia were previously defined. Relative risk and survival rate were measured successively by Cox proportional model and Kaplan-Meier curve. RESULTS: Of 71 ACS patients aged 56.8±9.5 years, 21 (29.5% subjects underwent CV events. Overall mean followup was 151.6 (95% CI: 129.7-173.5 days. Baseline characteristic were similarly distributed between groups with the highest quartile neopterin level (≥14.7 nmol/L than those with lowest quartile (≤6.2 nmol/L. Patients with the highest quartile had the worst survival curve than those with the lowest quartile (log-rank test; p=0.047. On Cox proportional model, relative risk of highest quartile group was 5.84 (95% CI: 1.19-28.47; p=0.029 compared to lowest quartile, after being adjusted with other predictors. CONCLUSIONS: Elevated serum neopterin is associated with increased risk of CV events in acute coronary syndromes. KEYWORDS: neopterin, cardiovascular events, acute coronary syndromes.

Polymeric nanoparticles (NPs) are widely used for drug delivery applications due to high biodegradability, low toxicity and high loading capacity. The focus of this study is the development of photosensitizer Photosens (PS) loaded albumin NPs for efficient photodynamic therapy (PDT). To fabricate PS-loaded bovine serum albumin nanoparticles (BSA-PS NPs), we used a coacervation method with glutaraldehyde followed by passive loading of PS. Successful loading of PS was confirmed by appearance of characteristic peak in absorption spectrum which allows to determine the PS loading in BSA NPs. The synthesized BSA-PS NPs demonstrated low toxicity to HeLa cells at therapeutic concentrations of loaded PS. Compared to free PS solution, the synthesized BSA-PS NPs generated the singlet oxygen more effectively under laser irradiation at 660 nm. In addition, due to presence of various chemical groups on the surface of BSA-PS NPs, they are capable to adsorb on cell surface and accumulate in cells due to cellular uptake mechanisms. Owing to combination of PD and cell uptake advantages, BSA-PS NPs demonstrated higher efficacy of photodynamic damage to cancer cells as compared to free PS at equivalent concentrations. These results suggest that non-targeted BSA-PS NPs with high PD activity and low-fabrication costs of are promising candidates for transfer to PD clinic treatments.

Carbohydrate-deficient transferrin (%CDT) is a well-established and highly specific biomarker for sustained heavy consumption of alcohol. However, in pregnant women, the specificity of this biomarker might be affected by advanced gestational age, even after accounting for increased transferrin concentrations in pregnancy. The goal of this prospective study was to assess the variability in %CDT during pregnancy among alcohol-abstaining patients. Patients were recruited during one of the first prenatal care visits and followed-up to term. Abstinence was confirmed by maternal self-report and by alcohol biomarkers. Biomarkers assessed in the mother included serum gamma-glutamyltranspeptidase, urine ethyl glucuronide and ethyl sulfate, and whole blood phosphatidylethanol (PEth). In addition, PEth was measured in a dry blood spot card obtained from a newborn. For %CDT analysis, serum samples were collected at baseline and at term and analyzed by an internationally validated high-performance liquid chromatography and spectrophotometric detection method. At recruitment (mean gestational age 22.6 ± 7.3 weeks), the mean %CDT concentration was 1.49 ± 0.30%, while at term, it increased to 1.67 ± 0.28% (P = 0.001). Using a conventional cutoff concentration %CDT >1.7%, 22.9 and 45.7% of the sample would be classified as 'positive' for this biomarker at recruitment and at term, respectively (P = 0.011 ). These results suggest that a conventional cutoff of 1.7% might be too low for pregnant women and would generate false-positive results. We propose that %CDT >2.0% be used as a cutoff concentration indicative of alcohol exposure in pregnant women. The sensitivity of %CDT at this cutoff for heavy drinking during pregnancy needs to be assessed further.

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

A case of symptomatic hyponatremia induced by hyperinsulinemia-euglycemia (HIE) therapy is reported. A 59-year-old, 81.65-kg woman with hypertension, major depressive disorder, and anxiety arrived at a tertiary medical center 1.5 hours after an intentional overdose of oral amlodipine 200 mg, metoprolol tartrate 2,000 mg, and isosorbide mononitrate 1,200 mg. Upon arrival, her pulse was 63 beats/min and blood pressure was 106/56 mm Hg. The patient's blood pressure was refractory to fluids, calcium gluconate, and norepinephrine, resulting in initiation of HIE therapy. She had recurrent episodes of hypoglycemia, which required increases of the dextrose infusion and resulted in the patient receiving a total of 6.9 L of dextrose with free water. Seventeen hours into the hospitalization, the patient became obtunded due to hyponatremia (serum sodium concentration, 121 mmol/L). HIE therapy was discontinued, an infusion of 5% dextrose injection with sodium bicarbonate added was started, and a bolus of 3% sodium chloride was administered. Nine hours after the presentation of hyponatremia, the patient's serum sodium concentration normalized (137 mmol/L), and her symptoms resolved. The patient's blood pressure, pulse, and mental status continued to improve, and the patient was transferred out of the medical intensive care unit 41 hours after her arrival at the hospital. A woman who overdosed on amlodipine, metoprolol tartrate, and isosorbide mononitrate was treated with HIE therapy and developed symptomatic hyponatremia. Hyponatremia resolved after administration of dextrose with sodium bicarbonate infusion and 3% sodium chloride infusion and cessation of HIE therapy.

The serum levels of ferritin in 394 patients, including 339 patients with various malignant tumors and 23 with various non-malignant diseases, and 32 healthy subjects were determined. The normal levels of ferritin were 82.7 +- 42.3 ng/ml for males and 42.0 +- 36.9 ng/ml for females. The positive ratio of serum ferritin level was 28% in patients with malignant tumors and 22% in patients with non-malignant diseases. The usefulness of serum ferritin assay in screening for malignant tumors appeared to be limited. High serum levels of ferritin were found in patients with malignant lymphoma (positive ratio: 42%), pulmonary cancer (38%) and esophageal cancer (37%). According to the histological types, epidermoid cancer appeared to produce a higher serum level of ferritin than adenocarcinoma in patients with pulmonary cancer. It was interesting that malignant lymphoma had a high serum level of ferritin in spite of its low serum level of CEA. Carcinoma of the digestive tracts except for esophagus was considered to have a normal serum ferritin level in spite of the advanced stage. There was no close relationship between serum ferritin levels and CEA levels in patients with pulmonary cancer and breast cancer. Serum CEA assay was more useful for detection of tumors than serum ferritin assay in patients with breast cancer. Serum ferritin levels in patients with good prognosis decreased following radiation therapy, but those in patients with poor prognosis elevated or unchanged in spite of therapy. Therefore, serial ferritin determinations may be useful for evaluation of radiotherapy and assessment of prognosis. (J.P.N.)

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

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

Sixty-four patients over the age of 40 years, undergoing elective surgery of at least one hour's duration, were randomized to treatment with either a thromboembolic deterrent ( TED ) stocking (Kendall Co.) or subcutaneous low-dose heparin 5 000 IU every 12 hours. Serum levels of alanine aminotransferase (S-ALAT), aspartate aminotransferase (S-ASAT), gamma-glutamyl transpeptidase (S-gamma-GT) and alkaline phosphatase (S-ALP) were measured. S-ALAT increased significantly on the 5th and 10th postoperative day, from 27 +/- 2 (x +/- SE) to 40 +/- 4 (p less than 0.01) and 55 +/- 7 U/l (p less than 0.001), respectively, in the heparin group and was significantly higher in the heparin than in the TED group both on the 5th (p less than 0.01) and 10th (p less than 0.05) postoperative day. S-ASAT and S-gamma-GT increased significantly during heparin treatment, but did not differ significantly from the values of the TED group. No change in S-ALP was registered in either group. It is concluded that prophylactic treatment with low-dose heparin induces a significant increase in S-aminotransferase levels, especially in S-ALAT. The phenomenon has profound differential diagnostic implications in conditions such as pulmonary embolism and acute myocardial infarction.

hADSCs transplantation in cirrhosis models improves liver function and reduces fibrosis. In addition, Ad-huPA gene therapy diminished fibrosis and increased hepatocyte regeneration. In this study, we evaluate the combination of these therapies in an advanced liver fibrosis experimental model. hADSCs were expanded and characterized before transplantation. Ad-huPA was simultaneously administrated via the ileac vein. Animals were immunosuppressed by CsA 24 h before treatment and until sacrifice at 10 days post-treatment. huPA liver expression and hADSCs biodistribution were evaluated, as well as the percentage of fibrotic tissue, hepatic mRNA levels of Col-αI, TGF-β1, CTGF, α-SMA, PAI-I, MMP2 and serum levels of ALT, AST and albumin. hADSCs homed mainly in liver, whereas huPA expression was similar in Ad-huPA and hADSCs/Ad-huPA groups. hADSCs, Ad-huPA and hADSCs/Ad-huPA treatment improves albumin levels, reduces liver fibrosis and diminishes Collagen α1, CTGF and α-SMA mRNA liver levels. ALT and AST serum levels showed a significant decrease exclusively in the hADSCs group. These results showed that combinatorial effect of cell and gene-therapy does not improve the antifibrogenic effects of individual treatments, whereas hADSCs transplantation seems to reduce liver fibrosis in a greater proportion.

2010-10-01

Full Text Available Abstract Introduction Radioiodine (131I therapy is widely accepted as an essential part of therapeutic regimens in many cases of differentiated thyroid cancer. Radiation-induced oxidative damage to macromolecules is a well known phenomenon. Frequently examined process to evaluate oxidative damage to macromolecules is lipid peroxidation (LPO, resulting from oxidative damage to membrane lipids. The aim of the study was to examine serum LPO level in hypothyroid (after total thyroidectomy cancer patients subjected to ablative activities of 131I. Materials and methods The study was carried out in 21 patients (18 females and 3 males, average age 52.4 ± 16.5 years after total thyroidectomy for papillary (17 patients or follicular (4 patients thyroid carcinoma. Hypothyroidism was confirmed by increased TSH blood concentration (BRAHMS, Germany, measured before 131I therapy. Activity of 2.8 - 6.9 GBq of 131I was administered to the patients orally as sodium iodide (OBRI, Poland. Concentrations of malondialdehyde + 4-hydroxyalkenals (MDA + 4-HDA, as an index of LPO (LPO-586 kit, Calbiochem, USA, were measured in blood serum just before 131I administration (day "0" and on the days 1-4 after 131I therapy. Sera from 23 euthyroid patients served as controls. Correlations between LPO and TSH or 131I activity were calculated. Results Expectedly, serum LPO level, when measured before 131I therapy, was several times higher (p 131I therapy. LPO did not correlate with TSH concentration. In turn, negative correlation was found between 131I activity and LPO level on the day "2" after radioiodine treatment. Conclusions Radioiodine remnant ablation of differentiated thyroid cancer does not further increase oxidative damage to membrane lipids, at least early, after therapy.

Observed adverse effects of antiretroviral therapy (ART) on the lipid profile could be of significance in pregnancy. This systematic review aims to summarize studies that investigated the association between HIV, ART and serum lipids during pregnancy and adverse pregnancy outcomes. A systematic search was conducted in five electronic databases to obtain articles that measured serum lipid concentrations or the incidence of dyslipidaemia in HIV-infected pregnant women. Included articles were assessed for quality according to the Cochrane Risk of Bias Tool. The extracted data was analysed through descriptive analysis. Of the 1264 articles screened, 17 articles were included in this review; eleven reported the incidence of dyslipidaemia, and twelve on maternal serum lipid concentrations under the influence of HIV-infection and ART. No articles reported pregnancy outcomes in relation to serum lipids. Articles were of acceptable quality, but heterogenic in methods and study design. Lipid levels in HIV-infected women increased 1.5-3 fold over the trimesters of pregnancy, and remained within the physiological reference range. The percentage of women with dyslipidaemia was variable between the studies [0-88.9%] and highest in the groups on first generation protease inhibitors and for women on ART at conception. This systematic review observed physiologic concentrations of serum lipids for HIV-infected women receiving ART during pregnancy. Serum lipids were increased in users of first generation protease inhibitors and for those on treatment at conception. There was no information available about pregnancy outcomes. Future studies are needed which include HIV-uninfected control groups, control for potential confounders, and overcome limitations associated with included studies.

Full Text Available Helicobacter pylori (H. pylori eradication is usually assessed using the 13C-urea breath test (UBT, anti-H. pylori antibody and the H. pylori stool antigen test. However, a few reports have used pepsinogen (PG, in particular, the percentage change in the PG I/II ratio. Here, we evaluated the usefulness of the percentage changes in serum PG I/II ratios for determining the success of eradication therapy for H. pylori.In total, 650 patients received eradication therapy from October 2008 to March 2013 in our Cancer Institute Hospital. We evaluated the relationship between H. pylori eradication and percentage changes in serum PG I/II ratios before and 3 months after treatment with CLEIA® (FUJIREBIO Inc, Tokyo, Japan. The gold standard of H. pylori eradication was defined as negative by the UBT performed 3 months after completion of eradication treatment. Cut-off values for percentage changes in serum PG I/II ratios were set as +40, +25 and +10% when the serum PG I/II ratio before treatment was below 3.0, above 3.0 but below 5.0 and 5.0 or above, respectively.Serum PG I and PG II levels were measured in 562 patients with H. pylori infection before and after eradication therapy. Eradication of H. pylori was achieved in 433 patients studied (77.0%. The ratios of first, second, third-line and penicillin allergy eradication treatment were 73.8% (317/429, 88.3% (99/112, 75% (12/16 and 100% (5/5, respectively. An increasing percentage in the serum levels of the PG I/II ratios after treatment compared with the values before treatment clearly distinguished success from failure of eradication (108.2±57.2 vs. 6.8±30.7, p<0.05. Using the above cut-off values, the sensitivity, specificity and validity for determination of H. pylori were 93.1, 93.8 and 93.2%, respectively.In conclusion, the percentage changes in serum PG I/II ratios are useful as evaluation criteria for assessing the success of eradication therapy for H. pylori.

Inflammatory mediators in both the peripheral circulation and central nervous system (CNS) are dysregulated in major depressive disorder (MDD). Nevertheless, relatively little is known about the role of the T-helper (Th)-2 effector cytokines interleukin (IL)-5 and IL-13 in MDD. We examined the serum levels of these cytokines and a Th-1 comparison cytokine, interferon (IFN)-γ, in 116 individuals (MDD, n = 58; controls, n = 58). In our basic multivariate model controlling for the effects of potential confounders on the associations between MDD and the examined cytokines, each 1-unit increase in the serum IL-5 level increased the likelihood of belonging to the MDD group by 76% (OR 1.76, 95% CI 1.03-2.99, p = 0.04; model covariates: age, gender, marital status, daily smoking and alcohol use). The likelihood further increased in models additionally controlling for the effects of the use of antidepressants and NSAIDS, and a diagnosis of asthma. No such associations were detected with regard to IL-13 (OR 1.08, 95% CI 0.96-1.22, p = 0.22) or IFN-γ (OR 1.02, 95% CI 0.99-1.05, p = 0.23). Elevated levels of IL-5, which uses the neural plasticity-related RAS GTPase-extracellular signal-regulated kinase (Ras-ERK) pathway to mediate its actions in the central nervous system (CNS), could be one of the factors underlying the depression-related changes in CNS plasticity.

Full Text Available BACKGROUND: Fibroblast growth factor 21 (FGF-21 is a metabolic regulator with multiple beneficial effects on glucose homeostasis and lipid metabolism in animal models. The relationship between plasma levels of FGF-21 and coronary heart disease (CHD in unknown. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to investigate the correlation of serum FGF-21 levels and lipid metabolism in the patients with coronary heart disease. We performed a logistic regression analysis of the relation between serum levels of FGF-21 and CHD patients with and without diabetes and hypertension. This study was conducted in the Departments of Endocrinology and Cardiovascular Diseases at two University Hospitals. Participants consisted of one hundred and thirty-five patients who have been diagnosed to have CHD and sixty-one control subjects. Serum FGF-21 level and levels of fasting blood glucose; triglyceride; apolipoprotein B100; HOMA-IR; insulin; total cholesterol; HDL-cholesterol; LDL-cholesterol; and C-reactive protein were measured. We found that median serum FGF-21 levels were significantly higher in CHD than that of control subjects (P<0.0001. Serum FGF-21 levels in CHD patients with diabetes, hypertension, or both were higher than that of patients without these comorbidities. Serum FGF-21 levels correlated positively with triglycerides, fasting blood glucose, apolipoprotein B100, insulin and HOMA-IR but negatively with HDL-C and apolipoprotein A1 after adjusting for BMI, diabetes and hypertension. Logistic regression analysis demonstrated that FGF-21 showed an independent association with triglyceride and apolipoprotein A1. CONCLUSIONS/SIGNIFICANCE: High levels of FGF-21 are associated with adverse lipid profiles in CHD patients. The paradoxical increase of serum FGF-21 in CHD patients may indicate a compensatory response or resistance to FGF-21.

This study aimed to investigate the relationship between serum vitamin D level and carotid intima-media thickness (C-IMT) in Chinese postmenopausal women. Nine hundred and twenty six Chinese postmenopausal women without carotid artery plaque or history of cardiovascular disease were selected for analysis. Measurements of serum 25 hydroxyvitamin D3 (25(OH)D3) concentration and C-IMT were made by electrochemiluminescence immunoassay and B-mode ultrasound, respectively. Trend analysis was conducted according to tertiles of C-IMT. The median serum 25(OH)D3 level was 11.03 ng/mL, with an interquartile range of 8.22-14.70. A decreasing trend of serum 25(OH)D3 level was accompanied by increased C-IMT tertiles (P for trend = 0.001). Correlation analysis found an inverse relationship between serum 25(OH)D3 level and C-IMT (r = -0.113, P = 0.001). After adjustment for confounding factors, multiple regression analysis showed that serum 25(OH)D3 level independently and negatively associated with C-IMT (Standard β = -0.112, P women with normal glucose tolerance, blood pressure and body mass index, and without undergoing lipid-lowering therapy (standard β = -0.140, P = 0.018). Serum 25(OH)D3 level was inversely correlated with C-IMT in Chinese postmenopausal women.

Full Text Available Mild traumatic brain injury (mTBI is one of the most common neuronal insults and can lead to long-term disabilities. mTBI occurs when the head is exposed to a rapid acceleration-deceleration movement triggering axonal injuries. Our limited understanding of the underlying pathological changes makes it difficult to predict the outcome of mTBI. In this study we used a scalable rat model for rotational acceleration TBI, previously characterized for the threshold of axonal pathology. We have analyzed whether a TBI just above the defined threshold would induce any detectable behavioral changes and/or changes in serum biomarkers. The effect of injury on sensory motor functions, memory and anxiety were assessed by beam walking, radial arms maze and elevated plus maze at 3 to 7 days following TBI. The only behavioral deficits found were transient impairments in working and reference memory. Blood serum was analyzed at 1, 3 and 14 days after injury for changes in selected protein biomarkers. Serum levels of neurofilament heavy chain (NF-H and Tau, as well as S100B and myelin basic protein (MBP showed significant increases in the injured animals at all time points. No signs of macroscopic injuries such as intracerebral hematomas or contusions were found. Amyloid precursor protein (APP immunostaining indicated axonal injuries at all time points analyzed. In summary, this model mimics some of the key symptoms of mTBI, such as transient memory impairment, which is paralleled by an increase in serum biomarkers. Our findings suggest that serum biomarkers may be used to detect mTBI. The model provides a suitable foundation for further investigation of the underlying pathology of mTBI.

To assess the comparative efficacy of IVF medium (MediCult, with 5.2 mM glucose) and a glucose/phosphate-free medium, P1 (Irvine Scientific), and to investigate the influence of increasing the serum supplementation (synthetic serum substitute; SSS; Irvine Scientific) to P1 on embryo development and implantation. Patients were randomly assigned to IVF medium (Group 1, cycles n = 172) or P1 supplemented with 10% SSS (Group 2, cycles n = 229) according to the medium scheduled for use on the day of oocyte retrieval. Another 555 IVF consequent cycles (Group 3) were performed using increased SSS concentrations (20%) in P1 medium. In this large series of IVF cycles, we herein demonstrate that significantly higher pregnancy and implantation rates were found when embryos were cultured in glucose/phosphate-free medium P1 supplemented with 20% SSS compared to supplementation with the lower SSS concentration and with IVF medium.

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

Serum levels of cholylglycines (CG) were determined by radioimmunoassay and that of total bile acids (TBA) by enzymatic method. In normal subjects, serum levels of CG, TBA and CG/TBA ratio were 0.6 +- 0.4 μM, 7 +- 2 μM, and 0.08 +- 0.06, respectively. They were increased markedly in acute hepatitis and moderately in chronic hepatitis and cirrhosis. Thus, measurement of serum CG as compared with serum TBA appears to be a sensitive liver test.

Variations of serum testosterone levels in prostate cancer patients under LH-releasing hormone therapy: an open question.

Science.gov (United States)

Reis, Leonardo Oliveira

The hypothesis 'the lower the better when achieving castration levels of testosterone' is based on the data from second-line hormonal manipulation and its molecular basis, and on better oncological results reported for lower castration levels in prostate cancer (PCa) patients, including those achieved with maximal androgen blockade. In this regard, the equivalence of surgical and different pharmacological castrations has been controversial. The modified amino acid structure that makes LH-releasing hormone (LHRH) analogs more potent than LHRH, and the method of delivering the analogs impacts on bioavailibility and potentially causes differences in androgen levels and in its final oncological efficacy. In addition to this, there is a myriad of circumstances, such as those related to ethnic variations and co-morbidities, which uniquely impact on the pharmacological approach in a highly heterogeneous population of castration-resistant prostate cancer (CRPC) patients. Ineffective testosterone suppression through hormonal escape is currently poorly recognized and may result in increased PCa mortality. Until now, the optimal serum testosterone level in patients under castration, and the impact of its variations in patients under LHRH therapy, remain open questions and have been merged to a broad spectra of patients who are highly heterogeneous. This heterogeneity relates to a number of mechanisms regarding response to treatment, which influences the biology of the relapsing tumor and the sensitivity to subsequent therapies in the individual patient. The rationale to achieve testosterone levels below 20-50 ng/dl warrant further investigation as these levels have recently rescued CRPC patients. In the last few years and months, important advancements in prostate cancer treatment have been achieved. Nevertheless, these advances are measured in a few months of additional survival and under high costs, not available to most of the world population, compared with the benefits

Brain-derived neurotrophic factor (BDNF) is an important neurotrophin. The present study investigated the effects of head-out water immersion (HOI) on serum BDNF concentrations. Eight healthy men performed 20 min head-out water immersion at 42 °C (hot-HOI) and 35 °C (neutral-HOI). These experimental trials were administered in a randomised order separated by at least 7 days. Venous blood samples were withdrawn at rest, immediately after the 20-min HOI, as well as at 15 and 30 min after the end of the HOI. Serum BDNF and S100β, plasma cortisol, platelet and monocyte counts, and core body temperature (T cb ) were measured. T cb was higher at the end of the hot-HOI and 15 min after hot-HOI (p hot-HOI. No change in T cb was recorded during neutral-HOI. BDNF level was higher (p hot-HOI and at 15 min after the end of hot-HOI, and returned to the baseline at 30 min after hot-HOI. S100β, platelet count and monocyte count remained stable throughout the study. Cortisol level was lower at the end of the hot-HOI and returned to pre-HOI level during the recovery period. BDNF and S100β, cortisol, and platelet and monocyte counts did not change throughout the neutral-HOI study. The present findings suggested that the increase in BDNF during 20-min hot-HOI was induced by hyperthermia through enhanced production, rather than by changes in permeability of the blood-brain barrier (BBB), platelet clotting mechanisms or secretion from monocytes.

Plants that undergo C 4 photosynthesis, such as maize, are enriched in the stable isotope of carbon ( 13 C) compared with other dietary plants and foods. Consumption of maize that has been biofortified to contain elevated levels of provitamin A carotenoids (orange maize) increased the abundance of 13 C in serum retinol of Mongolian gerbils. We evaluated this method in humans to determine if it has potential for further use in intervention effectiveness studies. A random subset of samples from a two-month randomized controlled feeding trial of rural three- to five-year old Zambian children were used to determine the impact of orange maize intake on serum carotenoid concentrations ( n = 88) and 13 C-natural abundance in serum retinol ( n = 77). Concentrations of β-cryptoxanthin (a xanthophyll provitamin A carotenoid) and the dihydroxy xanthophylls lutein and zeaxanthin, which do not have vitamin A activity, were elevated in children consuming orange maize compared with those consuming a white maize control ( P  0.3). Furthermore, 13 C natural abundance was higher after two months' intervention in the orange maize group compared with the white maize group ( P = 0.049). Predictions made from equations developed in the aforementioned gerbil study estimated that maize provided 11% (2-21%, 95% confidence interval) of the recent dietary vitamin A to these children. These results demonstrate that orange maize is efficacious at providing retinol to the vitamin A pool in children through provitamin A carotenoids, as monitored by the change in 13 C enrichment, which was not reflected in serum β-carotene concentrations. Further effectiveness studies in countries who have adopted orange maize should consider determining differences in retinol 13 C-enrichment among target groups in addition to profiling serum xanthophyll carotenoids with specific emphasis on zeaxanthin. Impact statement Maize biofortified with provitamin A carotenoids (orange) has been released

Full Text Available The measurement of serum tumor markers levels in breast cancer (BC patients is an economic and noninvasive diagnostic assay frequently requested by clinical oncologists to get information about the presence or absence of disease as well as its evolution. Despite their wide use in clinical practice, there is still an intense debate between scientific organizations about the real usefulness for patient monitoring during followup as well as response to therapy evaluation in case of advanced BC. In this review, we want to highlight the current recommendations published by scientific organizations about the use of “established” BC serum markers (CEA, TPA, TPS, CIFRA-21, CA15-3, and s-HER2 in clinical oncology practice. Moreover, we will focus on recent papers evidencing the usefulness of tumor markers levels measurement as a guide for the prescription and diagnostic integration of molecular imaging exams such as those performed by hybrid 18-fluorofeoxyglucose-positron emission tomography with integrated computed tomography. This technology is nowadays able to detect early cancer lesions undetectable by conventional morphological imaging investigation and most likely responsible for increasing of serum tumor markers levels.

Electroconvulsive therapy (ECT) is considered to be one of the most effective treatments for patients with major depression and persistent psychosis. Seizure characteristics probably determine the therapeutic effect of ECT; as a consequence, short seizures are accepted as one of the factors of poor outcome. During most ECT courses seizure threshold increases and seizure duration decreases. Methylxanthine preparations, caffeine, and theophylline have been used to prolong seizure duration. The use of aminophylline, more readily available than caffeine, has not been well documented. The objective of this study was to test the effects of aminophylline on seizure length. Fourteen drug-free patients with diagnoses of affective disorder or psychotic episode receiving ECT participated in this study. Seizure length was assessed clinically and per EEG. Statistical comparisons were done using paired t tests. A significant increase (p < 0.04) in seizure length was achieved and maintained on three subsequent treatments with aminophylline. No adverse events were noted from the addition of aminophylline.

Inflammation may play a central role in the pathogenesis of HIV-related Pneumocystis carinii pneumonia (PCP). Serum levels of the amino-terminal propeptide of Type III procollagen (PIIINP) reflect inflammatory activity in granulation tissue and in chronic rheumatic and liver disorders....... To investigate changes in PIIINP serum levels during an episode of HIV-related PCP, consecutive serum samples were taken from 48 HIV-infected patients with PCP in a randomized, placebo-controlled study of the effect of adjunctive methylprednisolone therapy (26 in corticosteroid [CS] group and 22 in control group......). All patients were treated with co-trimoxazole. In the control group, PIIINP serum levels at day of initiation of therapy (Day 0) were significantly higher in patients requiring mechanical ventilation and/or dying during the course of the pneumonia, and serum levels of PIIINP higher than 5 ng/ml were...

The current practice concerning timing, mode, and dose of renal replacement therapy (RRT) in patients with metformin-associated lactic acidosis (MALA) with renal failure remains unknown. To investigate whether serum lactate level and prescription pattern of RRT are associated with mortality in patients with MALA requiring RRT. We searched PubMed/Medline and EMBASE from inception to Sep 2014 and applied predetermined exclusion criteria. Case-level data including case's demographics and clinical information related to MALA were abstracted. Multiple logistic regression modeling was used to examine the predictors of mortality. A total of 253 unique cases were identified with cumulative mortality of 17.2%. Eighty-seven percent of patients had acute kidney injury. Serum lactate level was significantly higher in non-survivors (median 22.5 mmol/L) than in survivors (17.0 mmol/L, p-value optimal prescription of RRT in MALA, we recommend fostering an international consortium to support prospective research and large-scale standardized case collection.

Flavonoid rutin increases thyroid iodide uptake in rats.

Directory of Open Access Journals (Sweden)

Carlos Frederico Lima Gonçalves

Full Text Available Thyroid iodide uptake through the sodium-iodide symporter (NIS is not only an essential step for thyroid hormones biosynthesis, but also fundamental for the diagnosis and treatment of different thyroid diseases. However, part of patients with thyroid cancer is refractory to radioiodine therapy, due to reduced ability to uptake iodide, which greatly reduces the chances of survival. Therefore, compounds able to increase thyroid iodide uptake are of great interest. It has been shown that some flavonoids are able to increase iodide uptake and NIS expression in vitro, however, data in vivo are lacking. Flavonoids are polyhydroxyphenolic compounds, found in vegetables present in human diet, and have been shown not only to modulate NIS, but also thyroperoxidase (TPO, the key enzyme in thyroid hormones biosynthesis, besides having antiproliferative effect in thyroid cancer cell lines. Therefore, we aimed to evaluate the effect of some flavonoids on thyroid iodide uptake in Wistar rats in vivo. Among the flavonoids tested, rutin was the only one able to increase thyroid iodide uptake, so we decided to evaluate the effect of this flavonoid on some aspects of thyroid hormones synthesis and metabolism. Rutin led to a slight reduction of serum T4 and T3 without changes in serum thyrotropin (TSH, and significantly increased hypothalamic, pituitary and brown adipose tissue type 2 deiodinase and decreased liver type 1 deiodinase activities. Moreover, rutin treatment increased thyroid iodide uptake probably due to the increment of NIS expression, which might be secondary to increased response to TSH, since TSH receptor expression was increased. Thus, rutin might be useful as an adjuvant in radioiodine therapy, since this flavonoid increased thyroid iodide uptake without greatly affecting thyroid function.

Fifteen percent of patients who later have hemolysis, elevated liver enzymes, and low platelets syndrome develop initially have nonspecific symptoms. Early diagnosis could ensure adequate obstetric management; however, prognostic biochemical tests are lacking. We hypothesized that elevated hyaluronic acid serum levels might be an early indicator of hemolysis, elevated liver enzymes, and low platelets syndrome because it is known to be a sensitive marker of liver cell function. Hyaluronic acid in serum was measured in patients with normal pregnancies (n = 109) and in those patients with pregnancies complicated by preeclampsia (n = 14) or hemolysis, elevated liver enzymes, and low platelets syndrome (n = 11). A significant increase in hyaluronic acid serum concentrations was observed in patients with hemolysis, elevated liver enzymes, and low platelets syndrome or with preeclampsia (p hyaluronic acid serum levels in hemolysis, elevated liver enzymes, and low platelets syndrome correlated with the clinical severity of the individual course of disease as measured by intensive care unit time (r = 0.72; p hyaluronic acid in preeclampsia and hemolysis, elevated liver enzymes, and low platelets syndrome are significantly elevated and might play an important diagnostic and prognostic role in patients with hemolysis, elevated liver enzymes, and low platelets syndrome.

A prospective study of 342 patients with subjective or objective mild cognitive impairment recruited at a single memory clinic. We determined whether serum IGF-I concentrations at baseline were associated with the risk of all-cause dementia, AD, or VaD. Patients developing mixed forms of AD and VaD were defined as suffering from VaD. The statistical analyses included Cox proportional hazards regression analysis. During the follow-up (mean 3.6 years), 95 (28%) of the patients developed all-cause dementia [AD, n=37 (11%) and VaD, n=42 (12%)]. Low as well as high serum IGF-I (quartile 1 or 4 vs. quartiles 2-3) did not associate with all-cause dementia [crude hazard ratio (HR) 1.30, 95% confidence interval (CI): 0.81-2.08 and crude HR 1.05, 95% CI: 0.63-1.75, respectively] or AD (crude HR 0.79, 95% CI: 0.35-1.79 and crude HR 0.94, 95% CI: 0.43-2.06, respectively]. In contrast, low serum IGF-I concentrations were associated with increased risk of VaD (quartile 1 vs. quartiles 2-3, crude HR 2.22, 95% CI: 1.13-4.36). The latter association remained significant also after adjustment for multiple covariates. In a memory clinic population, low serum IGF-I was a risk marker for subsequent VaD whereas low IGF-I did not associate with the risk of AD. High serum IGF-I was not related to the risk of conversion to dementia. Copyright © 2017 Elsevier Ltd. All rights reserved.

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

Modulation of synergistic cardiotoxicity of doxorubicin and radiation therapy by propionyl l-carnitine

2002-01-01

Combined radiotherapy and chemotherapy have represented a major advance in the therapeutic management of cancer therapy. However, the combination of Doxorubicin (DOX) and irradiation (IRR) may be more cardiotoxic than either agent. Propionyl-L-carnitine (PLC) is a naturally occurring derivative of L-carnitine that has been considered in the treatment of many forms of cardiomyopathies. In this study, the possible mechanism (S) whereby PLC couls protect against DOX and/or IRR-induced cardiomyopathy were carried out. Administration of DOX as a single dose (5 mg/Kg) or cumulative dose (15 and 25 mg/kg divided into 3 and 5 equal doses 5 mg/kg each, every other day) resulted in significant and dose dependent increase in serum cardiac enzymes (CPK, GOT and LDH) in rat, MDA level and nitric oxide in heart tissue and dose dependent decrease in the antioxidant enzymes (SOD) and GSHPx). Whole body irradiation (2 Gy) induced similar effect to DOX. Combination of DOX and IRR resulted in marked elevation in cardiac enzymes and MDA level and remarkable decrease in the antioxidant enzymes . PLC (250 mg/kg, for 9 days) before DOX and /or IRR induced significant increase in the activity of SOD and GSHPx and significantly decreased the level of MDA and nitric oxide in rat cardiac tissue and the activity of cardiac enzymes in rat serum. Also, DOX-induced dose dependent increase in AC/FC ratio above the normal value (0.4) in serum and heart tissue. Combination of DOX and IRR increased the ratio. Administration of PLC to DOX and/or IRR resulted in partial reversal of DOX induced increase in the AC/FC ratio except for the highest cumulative dose (25 mg/kg) in serum. Dox induced dose-dependent increase in DOX concentration in serum and heart tissue. Administration of PLC decreased DOX concentration in heart with an increase in DOX concentration in serum. IRR did not alter DOX concentration. Worth mentioning os that PLC had no effect on the antitumor activity of DOX and/ or IRR in solid

The on-field diagnosis of sports-related concussion (SRC) is complicated by the lack of an accurate and objective marker of brain injury. To compare subject-specific changes in the astroglial protein, S100B, before and after SRC among collegiate and semi-professional contact sport athletes, and compare these changes to differences in S100B before and after non-contact exertion. Longitudinal cohort study. From 2009-2011, we performed a prospective study of athletes from Munich, Germany, and Rochester, New York, USA. Serum S100B was measured in all SRC athletes at pre-season baseline, within 3 hours of injury, and at days 2, 3 and 7 post-SRC. Among a subset of athletes, S100B was measured after non-contact exertion but before injury. All samples were collected identically and analyzed using an automated electrochemiluminescent assay to quantify serum S100B levels. Forty-six athletes (30 Munich, 16 Rochester) underwent baseline testing. Thirty underwent additional post-exertion S100B testing. Twenty-two athletes (16 Rochester, 6 Munich) sustained a SRC, and 17 had S100B testing within 3 hours post-injury. The mean 3-hour post-SRC S100B was significantly higher than pre-season baseline (0.099±0.008 µg/L vs. 0.058±0.006 µg/L, p = 0.0002). Mean post-exertion S100B was not significantly different than the preseason baseline. S100B levels at post-injury days 2, 3 and 7 were significantly lower than the 3-hour level, and not different than baseline. Both the absolute change and proportional increase in S100B 3-hour post-injury were accurate discriminators of SRC from non-contact exertion without SRC (AUC 0.772 and 0.904, respectively). A 3-hour post-concussion S100B >0.122 µg/L and a proportional S100B increase of >45.9% over baseline were both 96.7% specific for SRC. Relative and absolute increases in serum S100B can accurately distinguish SRC from sports-related exertion, and may be a useful adjunct to the diagnosis of SRC.

Objective: To study the changes of serum lipid profile after withdrawl of levo-thyroxine replacement for 4 weeks in patient with radical thyroidectomy for cancer. Methods: Serum thyroid hormones (FT 3 , FT 4 , sTSH, with RIA) levels and lipid profile (Total cholesterol, triglycerides, LDL, HDL, apolipoprotein A-I, apolipoprotein B and Lp (a), with biochemistry) were determined in 46 patients with thyroid carcinoma after operation both during and after 4 weeks' withdrawl of levo-thyroxine replacement treatment. Results: Serum FT 3 , FT 4 levels decreased significantly and serum sTSH, TC, TG, LDL, apo-B, Lp (a) levels increased significantly after 4 weeks' withdrawl of levo-thyroxine replacement (vs during treatment, P 0.05). Conclusion: Hyperlipidaemia did develop in the hypothyroid patients after withdrawl of levo-thyroxine replacement but the degree of which did not not necessarily correlate with the increment of sTSH levels.

A specific radioimmunoassay is described which allows the simultaneous determination of serum corticosterone and deoxycortisol. The normal serum concentration of both steroids were found to be dependent on sex and menstrual cycle. Mean concentrations (+-S.D.) in males, females (follicular phase) and females (luteal phase) were 4210 +- 2170 ng/l, 2410 +- 1480 ng/l and 4390 +- 2320 ng/l for corticosterone and 499 +- 273 ng/l, 207 +- 152 ng/l and 335 +- 182 ng/l for deoxycortisol. After adrenal stimulation by corticotropin itself or by insulin induced hypoglycemia, the serum concentrations of corticosterone became significantly higher than those of deoxycortisol. After oral administration of dexamethasone serum concentrations of both steroids were suppressed to levels below the limit of the normal range. One hour after oral metyrapone administration at midnight, serum corticosterone decreased, while serum deoxycortisol increased by a factor of about five. After eight hours serum concentrations of both steroids were increased considerably. Corticosterone attained levels slightly higher than the normal range and deoxycortisol rose to levels which were higher than the normal mean concentrations by a factor of about 500. (orig./AS) [de

Tumor necrosis factor (TNF)-α inhibitor has been shown to affect the periodontal condition of patients with rheumatoid arthritis (RA). The aim of the present study is to assess the effect of a fully humanized anti-TNF-α monoclonal antibody, adalimumab (ADA), on the periodontal condition of patients with RA and to compare serum protein profiles before and after ADA therapy. The study participants consisted of 20 patients with RA treated with ADA. Clinical periodontal and rheumatologic parameters and serum cytokine levels were evaluated at baseline and 3 months later. Serum protein spot volume was examined with two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis. Proteins with significant difference in abundance before and after ADA therapy were found and identified using mass spectrometry and protein databases. The patients showed a significant decrease in gingival index (P = 0.002), bleeding on probing (P = 0.003), probing depth (P = 0.002), disease activity score including 28 joints using C-reactive protein (P protein spots obtained, nine spots were significantly decreased in abundance at reassessment, corresponding to complement factor H, phospholipase D, serum amyloid A, complement component 4, and α-1-acid glycoprotein (P periodontal condition of patients with RA, which might be related to differences in serum protein profiles before and after ADA therapy.

To evaluate metabolic control and safety parameters (hypoglycaemia frequency and nasal mucosa physiology), 31 insulin-dependent diabetic patients were treated with intranasal insulin at mealtimes for 1 month and with subcutaneous fast-acting insulin at meals for another month in an open, crossover...... randomized trial. During both treatment periods the patients were treated with intermediate-acting insulin at bedtime. Six of the patients were withdrawn from the study during intranasal insulin therapy due to metabolic dysregulation. Serum insulin concentrations increased more rapidly and decreased more...... quickly during intranasal as compared with subcutaneous insulin administration. Metabolic control deteriorated, as assessed by haemoglobin A1c concentrations, slightly but significantly after intranasal as compared with subcutaneous insulin therapy. The bioavailability of intranasally applied insulin...

This post hoc analysis of the CSPPT (China Stroke Primary Prevention Trial) assessed the individual variation in total homocysteine (tHcy)-lowering response after an average 4.5 years of 0.8 mg daily folic acid therapy in Chinese hypertensive adults and evaluated effect modification by methylenetetrahydrofolate reductase ( MTHFR ) C677T genotypes and serum folate levels. This analysis included 16 413 participants from the CSPPT, who were randomly assigned to 2 double-blind treatment groups: either 10-mg enalapril+0.8-mg folic acid or 10-mg enalapril, daily and had individual measurements of serum folate and tHcy levels at baseline and exit visits and MTHFR C677T genotypes. Mean baseline tHcy levels were comparable between the 2 treatment groups (14.5±8.5 versus 14.4±8.1 μmol/L; P =0.561). After 4.5 years of treatment, mean tHcy levels were reduced to 12.7±6.1 μmol/L in the enalapril+folic acid group, but almost stayed the same in the enalapril group (14.4±7.9 μmol/L, group difference: 1.61 μmol/L; 11% reduction). More importantly, tHcy lowering varied by MTHFR genotypes and serum folate levels. Compared with CC and CT genotypes, participants with the TT genotype had a more prominent L-shaped curve between tHcy and serum folate levels and required higher folate levels (at least 15 ng/mL) to eliminate the differences in tHcy by genotypes. Compared with CC or CT, tHcy in the TT group manifested a heightened L-shaped curve from low to high folate levels, but this difference in tHcy by genotype was eliminated when plasma folate levels reach ≈15 ng/mL or higher. Our data raised the prospect to tailor folic acid therapy according to individual MTHFR C677T genotype and folate status. URL: http://www.clinicaltrials.gov.

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

The change and the prognostic value of serum hepatocyte growth factor and AFP level in patients with cirrhosis and/or primary liver cancer (HCC) were investigated. The level of serum hepatocyte growth factor was determined by using enzyme-linked immunosorbent assay, and AFP was determined by using radioimmunoassay in 29 patients with cirrhosis. Twenty five patients with primary liver cancer (13 patients without nodular cirrhosis and 12 patients with nodular cirrhosis) were categorized according to tumour size (≤ or >5 cm) and the level of AFP (≤ or > 200 ng/dl). The correlation between serum AFP and hepatocyte growth factor were significantly increased (P 0.05). Serum AFP can significantly discriminate between all studied groups (P 0.001) except for the comparison between control and cirrhosis (P>0.05), and also between HCC and HCC without nodular cirrhosis and HCC with cirrhosis (P>0.05). Serum HGF and AFP levels were positively affected by tumour size and nodular cirrhosis (P<0.001). Also, serum HGF level was highly affected by the levels of serum AFP in HCC patients. Non-significant correlation was observed between serum hepatocyte growth factor and AFP in control, cirrhosis, cirrhosis and HCC patients with AFP ? 200 ng/dl. It could be concluded that the over expressions of the hepatocyte growth factor and AFP may indicate an adverse prognosis for patients with cirrhosis and/or liver cancer. The sustained high level of serum hepatocyte growth factor in cirrhosis and/or HCC could be considered a factor related to early tumour diagnosis, so, serum HGF level may be used as a non-invasive marker in diagnosis and prognosis of liver malignancy. However, further studies are highly recommended to evaluate the role of HGF or its constituents in diagnosis and/or therapy in the future in a larger cohort of patients with different stages of liver malignancy

Full Text Available BACKGROUND Serum paraoxonase is an enzyme synthesised in the liver. It is known to prevent atherosclerosis by inhibiting oxidation of lowdensity lipoprotein. Renal transplant recipients have increased tendency for developing atherosclerosis and cardiovascular disease. Reduced activity of serum paraoxonase contributes to accelerated atherosclerosis and increased cardiovascular complications in these patients. The aim of this study was to estimate serum paraoxonase activity in renal transplant recipients and compare it with healthy controls. MATERIALS AND METHODS 30 renal transplant recipients and 30 age and sex matched healthy controls were taken for the study. Serum paraoxonase activity, blood urea, serum creatinine and uric acid were estimated in these groups. The serum paraoxonase activity was correlated with urea, creatinine and uric acid levels. RESULTS Serum paraoxonase activity was reduced in renal transplant recipients compared to healthy controls. There was a negative correlation between paraoxonase activity and the levels of urea, creatinine and uric acid levels. CONCLUSION In this study, the paraoxonase activity was reduced in renal transplant recipients compared to controls. The increased cardiovascular disease in these patients could be due to reduced paraoxonase activity.

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

Purpose: To determine the expected time to serum testosterone normalization after short-course neoadjuvant androgen deprivation therapy (NAAD) and three-dimensional conformal radiotherapy for patients with localized prostate cancer and to identify pretreatment predictors that correlated with the time to testosterone normalization. Methods: Between 1993 and 1999, 88 patients with localized prostate cancer, treated with NAAD and external beam radiotherapy, were prospectively monitored after treatment with sequential testosterone levels. NAAD was administered before and during the entire course of radiotherapy and discontinued at the end of treatment. The median duration of NAAD was 6 months. The actuarial rate of serum testosterone normalization from the end of treatment was evaluated, and the presence or absence of androgen deprivation-related symptoms was correlated with serum testosterone levels. Symptoms assessed included weight gain, loss of libido, breast tenderness, breast enlargement, hot flashes, and fatigue. Results: Serum testosterone levels returned to the normal range in 57 (65%) of the 88 patients and failed to normalize in 31 patients (35%). The median time to normalization was 18.3 months. The actuarial rate of normalization at 3, 6, 12, and 24 months was 10%, 26%, 38%, and 59%, respectively. In a multivariate analysis, a pretreatment testosterone level in the lower range of normal was the only variable that predicted for delayed testosterone normalization after NAAD (p=0.00047). Among 45 patients with information concerning androgen deprivation-related symptoms recorded 1 year after cessation of NAAD, 24 (53%) had normalized testosterone levels, but in 21 patients (47%), the levels had not yet returned to normal. At 1 year, only 1 (4%) of 24 patients whose testosterone level had returned to normal experienced NAAD-related symptoms compared with 14 (67%) of 21 patients who did not have normal testosterone levels (p<0.001). Conclusion: Testosterone

Irregularities of serotonin function in irritable bowel syndrome (IBS) may be due to changes in the metabolism of the serotonin precursor l-tryptophan. Dietary alteration of tryptophan intake may impact upon the mood and bowel symptoms of IBS. We hypothesized that diarrhea-predominant irritable bowel syndrome (d-IBS) patients would exhibit an increase in plasma tryptophan due to alterations in tryptophan metabolism. We also hypothesized that a diet low in tryptophan would reverse this change and reduce symptoms. Thirteen patients with d-IBS had fasting serum free and total tryptophan, large neutral amino acids, and 6 kynurenine metabolites measured before and after 2 weeks of a strict dairy-free diet. Baseline tryptophan parameters were compared with an age- and sex-matched control group. Changes in the specific tryptophan parameters before and after dairy-free diet were correlated with symptoms of IBS and mood. Compared with the control group, d-IBS patients at baseline exhibited significantly higher free serum tryptophan (10.5 ± 4.35 vs 4.75 ± 2.43 μmol/L [means ± standard deviation], P = .006) and significantly lower tryptophan dioxygenase and total tryptophan oxidation as measured by the kynurenine to free tryptophan and total kynurenines to free tryptophan ratios (23.37 ± 10.12 vs 55.33 ± 16.02, P < .001 and 49.34 ± 17.84 vs 258.46 ± 98.67, P < .001, respectively). Dairy-free diet did not modulate metabolites of the kynurenine pathway or symptoms. Tryptophan metabolism along the kynurenine pathway is inhibited in d-IBS, and a dairy-free diet does not alter this. Our findings are consistent with possible enhanced serotonin activity in d-IBS.

Sustained cell stress can lead to several health complications, such as extensive inflammatory responses, tumor growth, and necrosis. To prevent disease and protect human tissue during these conditions and to avoid medication side effects, nanomaterials with unique characteristics have been applied to biological systems. This paper introduces the pretreatment in human dermal fibroblasts with cerium oxide nanoparticles during nutritional stress. For this purpose, human dermal fibroblast cells received cell culture media with concentrations of 250 µg/mL and 500 µg/mL of nano-cerium oxide before being exposed to 24, 48, and 72 hours of serum starvation. Contrast images demonstrated higher cell confluence and cell integrity in cells pretreated with ceria nanoparticles compared to untreated cells. It was confirmed by MTS assay after 72 hours of serum starvation that higher cell viability was achieved with ceria nanoparticles.

Objective: To investigate the changes of serum insulin-like growth factor-1(IGF-1) and growth hormone (GH) levels in patients with Graves' disease (GD). Methods: The serum IGF-1 and GH levels were determined with RIA in 42 cases of GD, 20 cases of GD patients after therapy (in euthyroid state) and 30 normal controls. Results: The level of serum IGF-1 (170.8±44.4 ng/ml) and GH (2.80±1.18 ng/ml) were significantly higher in GD patients than those in controls [IGF-1 (90.5±30.5 ng/ml), GH(1.58±1.20 ng/ml)] (p<0.01, p<0.05). IGF-1 levels were positively correlated to FT4 levels (r=0.58, p<0.01). The levels of serum IGF-1 (110.4±33.2 ng/ml) and GH (1.71±1.36 ng/ml) after treatment were significantly lower than those before treatment (p<0.01, p<0.05). Conclusion: The levels of serum IGF-1 and GH were markedly increase in GD patients and might be influenced by changes of thyroid hormone levels

Full Text Available Background Pre-eclampsia is a serious hypertensive condition of pregnancy associated with high maternal and fetal morbidity and mortality. Women who have had pre-eclampsia have a greater risk of developing hypertension, stroke and ischemic heart disease in later life. The etiology of pre-eclampsia remains unclear. Placental insufficiency plays a key role in the progression of this disease. The aim of this study was to determine membrane potential, serum calcium and serum selenium levels in preeclampsia subjects in Owerri.   Methods A case control study involving 200 primigravida (100 preeclamptic and 100 apparently healthy between the ages of 20 and 32 years attending General Hospital Owerri. Fasting venous blood was collected for the determination of serum selenium and serum calcium while membrane potential was calculated using the Nernst equation. The serum calcium was estimated using Randox Kit and serum selenium by atomic absorption spectrophotometry. The Independent Student t test was used for statistical analysis.   Results The results revealed that membrane potential and serum selenium as well as serum calcium were significantly decreased in preeclampsia when compared with the controls, at p<0.05.   Conclusion Our study demonstrated that the decrease in membrane potential, serum calcium and serum selenium levels may play a critical role in the pathogenesis of pre-eclampsia. There may be a need for increasing the dietary intake of these essential trace metals during pregnancy to prevent pre-eclampsia in Owerri.

Carboxy-terminal pyridinoline cross-linked telopeptide of type I collagen (ICTP) in serum has recently been proposed as a new biochemical marker of bone resorption. In the present study we compared serum ICTP with radiopharmaceutical and histomorphometric measurements of bone turnover...... in postmenopausal women with mild osteoporosis, and assessed the effect of hormone replacement therapy (HRT) (2 mg 17 beta-estradiol plus 1 mg norethisterone daily) and anabolic steroid therapy (50 mg nandrolone decanoate (ND) i.m. every 3 weeks) on serum ICTP in two double-blind placebo-controlled studies with 55...... to 75-year-old women. Serum ICTP measured by radioimmunoassay (RIA) correlated significantly with the 24-hour whole body retention of 99m-technetium diphosphonate (Rho = 0.47, P

Serum thymidine kinase (S-TK) was measured weekly in 16 randomly selected patients with AIDS or AIDS-related complex (ARC; Centers for Disease Control group IV A or group IV C-2) who participated in a controlled study of the efficacy of zidovudine therapy. S-TK increased significantly (P less than...... 0.01) in the zidovudine group, whereas it remained stable in the placebo (control) group. On the basis of this observation, the value of S-TK measurements as a predictor of bone marrow toxicity during zidovudine therapy was investigated in 42 patients with AIDS or ARC who received zidovudine as part...... of their usual treatment. There was a significant association between S-TK, haemoglobin and neutrophil counts measured after the first 4 weeks of therapy and the risk of developing bone marrow toxicity during the following 6 months. Combined, measurements of S-TK and neutrophil counts seem to be well suited...

Full Text Available Background: Iron supplementation can decrease the absorption of zinc and influence other antioxidants levels such as vitamin C. This study aimed to investigate the effect of iron supplements alone and in combination with vitamin C on zinc and vitamin C status in iron deficient female students. Methods: In a double-blind randomized clinical trail, 60 iron deficient students were selected from 289 volunteers residing in dormitory. After matching, subjects were randomly assigned into two groups: Group I (50 mg elemental iron supplements and Group II (50 mg elemental iron + 500 mg ascorbic acid. Serum ferritin, iron, serum zinc, and plasma vitamin C concentrations were measured by using enzyme-linked immunosorbent assay, spectrophotometer, atomic absorption spectrometer, and colorimeter, respectively after 6 and 12 weeks supplementation. Student′s t-test and repeated measures analysis of variance were applied to analyze the data using SPSS software. Results: Serum zinc levels had no significant differences between 2 groups at the baseline; however, its concentration decreased from 80.9 ± 4.2-68.9 ± 2.7 μg/dl to 81.2 ± 4.5-66.1 ± 2.9 μg/dl (P < 0.001 in Groups I and II, respectively after 6 weeks of supplementation. Continuous supplementation increased serum zinc concentration to baseline levels (79.0 ± 2.9 μg/dl; P < 0.01 in Group I and 70.5 ± 3.1 μg/dl in Group II following 12 weeks of supplementation. Plasma vitamin C increased from 3 ± 0/1-3.3 ± 0.2 mg/dl to 2.7 ± 0. 1-4.2 ± 0.2 mg/dl (P < 0.01 in Groups I and II, respectively. At the end of study, plasma vitamin C significantly increased from 3.3 ± 0.3-4.7 ± 0.3 (P < 0.01 to 4.2 ± 0.2-7.1 ± 0.2 (P < 0.001 in Groups I and II, respectively. Conclusions: Iron supplementation with and without vitamin C led to reduction in serum Zn in iron-deficient female students after 6 weeks. However, the decreasing trend stops after repletion of iron stores and Zn levels returned to the

There is increasing evidence that circulating levels of soluble CD30 (sCD30) may represent a biomarker for outcome in kidney transplantation. The aim of this study was to measure the pre- and posttransplantation serum levels of sCD30 in cadaveric kidney transplant recipients and correlate them with serum creatinine. Serum sCD30 was measured by a commercial enzyme-linked immunosorbent assay (ELISA) from prospective samples of 38 kidney allograft recipients serially transplanted at our center. Samples were collected at day 0 pretransplantation and at months 6, 12, 18, and 24 posttransplantation. We also studied sera from 29 patients with chronic kidney disease (CKD) at different stages of the K/DOQI guidelines, as a control group. Serum levels of sCD30 decreased significantly in samples posttransplantation compared with pretransplantation. The significant decrease after transplantation may be related to the improvement in renal function since we observed a significant correlation between serum levels of sCD30 and creatinine (sCr) at all times of the study. In addition, the patients with chronic renal failure showed a significant association between serum sCD30 and sCr (r = .454; P = .013). Our results did not suggest that the measurement of sCD30 may be used as a valuable biomarker in renal transplantation. Increased levels may be related to a decrease in its renal elimination.

With the increase of people"s living standard and the changes of living form, the number of people who suffer from hypercholesterolemia is increasing. It is not only harmful to heart and blood vessel, but also leading to obstruction of cognition. The conventional blood detection technology has weakness such as complex operation, long detecting period, and bad visibility. In order to develop a new detection method that can checkout hypercholesterolemia conveniently, spectroscopy of cholesterol in hypercholesterolemia serum is obtained by the multifunctional grating spectrograph. The experiment results indicate that, under the excitation of light-emitting diode (LED) with the wavelength at 407 nm, the serum from normal human and the hypercholesterolemia serum emit different fluorescence spectra. The former can emit one fluorescence region with the peak locating at 516 nm while the latter can emit two more regions with peaks locating at 560 nm and 588 nm. Moreover, the fluorescence intensity of serum is non-linear increasing with the concentration of cholesterol increases when the concentration of cholesterol is lower than 13.8 mmol/L, and then, with the concentration of cholesterol increase, the fluorescence intensity decreases. However, the fluorescence intensity is still much higher than that of serum from normal human. Conclusions can be educed from the experiments: the intensity and the shape of fluorescence spectra of hypercholesterolemia serum are different of those of normal serum, from which the cholesterol abnormal in blood can be judged. The consequences in this paper may offer an experimental reference for the diagnosis of the hypercholesterolemia.

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

Pancreatitis is associated with intraductal papillary mucinous neoplasm (IPMN). This association is in part due to inflammation from pancreatic ductal obstruction. Although the correlation between pancreatitis and the malignant potential of IPMN is unclear, the 2012 International Consensus Guidelines (ICG) consider pancreatitis a "worrisome feature." We hypothesized that serum pancreatic enzymes, markers of inflammation, are a better predictor of malignancy than pancreatitis in patients with IPMN. Between 1992 and 2012, 364 patients underwent resection for IPMN at a single university hospital. In the past decade, serum amylase and lipase were collected prospectively as an inflammatory marker in 203 patients with IPMN at initial surveillance and "cyst clinic" visits. The latest serum pancreatic enzyme values within 3 months preoperatively were studied. Pancreatitis was defined according to the 2012 revision of the Atlanta Consensus. Of the 203 eligible patients, there were 76 with pancreatitis. Pancreatitis was not associated with an increased rate of malignancy (P = .51) or invasiveness (P = .08). Serum pancreatic enzymes categorically outside of normal range (high or low) were also not associated with malignancy or invasiveness. In contrast, as a continuous variable, the higher the serum pancreatic enzymes were, the greater the rate of invasive IPMN. Of the 127 remaining patients without pancreatitis, serum pancreatic enzymes outside of normal range (low and high) were each associated with a greater rate of malignancy (P enzyme levels above normal range (high) were associated with a greater rate of invasiveness (P = .02). In patients with IPMN without a history of pancreatitis, serum pancreatic enzymes outside of the normal range are associated with a greater risk of malignancy. In patients with a history of pancreatitis, there is a positive correlation between the levels of serum pancreatic enzymes and the presence of invasive IPMN. These data suggest

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

Radioimmunoassay for 3,3',5'-triiodo-L-thyronine in unextracted serum: method and clinical results. [/sup 125/I

Serum 3,3',5'-triiodothyronine (rT/sub 3/) was measured with a radioimmunoassay in unextracted serum. The assay was specific and reproducible. The coefficients of variation for three different sera known for high, normal, and low rT/sub 3/ concentrations between assays were 4, 6, and 9 percent and within assays 4, 9, and 7 percent, respectively. In euthyroid subjects 20 to 60 years old, rT/sub 3/ was 450 +- 200 pg/ml (mean +- SD, n = 83). Serum rT/sub 3/ was found to be increased in hyperthyroidism (range: 762 to 2581 pg/ml; n = 11) but also in acute and chronic illness (up to 2400 pg/ml; n = 24) and in anorexia nervosa (536 to 1058 pg/ml; n = 7). In the latter two situations there was mostly an inverse change in serum 3,5,3'-triiodothyronine (T/sub 3/) which was in the low normal range or decreased. These findings suggest a metabolic control of thryoxine deiodination. A low serum rT/sub 3/ was found in 9 of 12 hypothyroid patients and in the serum of one chronically ill patient. Long-term treatment (1 to 7 years) with lithium carbonate slightly reduced serum rT/sub 3/, although the changes were inside the normal range. Kidney function was not found to be necessary for its production, as anephric patients had normal rT/sub 3/ values. In addition, hemodialysis increased serum rT/sub 3/, which is probably due to the heparin therapy.

Full Text Available Abstract Background Resistin, secreted from adipocytes, causes insulin resistance in mice. The relationship between resistin and coronary artery disease is highly controversial, and the information regarding resistin and ischemic stroke is limited. In the present study, the association between serum resistin concentration and cardiovascular disease (CVD was investigated in a general Japanese population. Methods A total of 3,201 community-dwelling individuals aged 40 years or older (1,382 men and 1,819 women were divided into quintiles of serum resistin, and the association between resistin and CVD was examined cross-sectionally. The combined effect of either diabetes or hypertension and high serum resistin was also assessed. Serum resistin was measured using ELISA. Results Compared to those without CVD, age- and sex-adjusted mean serum resistin concentrations were greater in subjects with CVD (p = 0.002 or ischemic stroke (p Conclusion Elevated serum resistin concentration appears to be an independent risk factor for ischemic stroke, especially lacunar and atherothrombotic infarction in the general Japanese population. The combination of high resistin and the presence of either diabetes or hypertension increased the risk of ischemic stroke.

The optimum model of physiotherapy service delivery for maximizing active task practice during rehabilitation after stroke is unknown. The purpose of the study was to examine the relative effectiveness of 2 alternative models of physiotherapy service delivery against a usual care control with regard to increasing patient activity. Substudy within a large 3-armed randomized controlled trial, which compared 3 different models of physiotherapy service delivery, was provided for 4 weeks during subacute, inpatient rehabilitation (n=283). The duration of all physiotherapy sessions was recorded. In addition, 32 participants were observed at 10-minute intervals for 1 weekday and 1 weekend day between 8:00 am and 4:30 pm. At each observation, we recorded physical activity, location, and people present. Participants receiving 7-day-week and circuit class therapy received an additional 3 hours and 22 hours of physiotherapy time, respectively, when compared with usual care. Participants were standing or walking for a median of 8.2% of observations. On weekdays, circuit class therapy participants spent more time in therapy-related activity (10.2% of observations) when compared with usual care participants (6.1% of observations). On weekends, 7-day therapy participants spent more time in therapy-related activity (4.2% of observations) when compared with both usual care and circuit class therapy participants (0% of observations for both groups). Activity levels outside of therapy sessions did not differ between groups. A greater dosage of physiotherapy time did not translate into meaningful increases in physical activity across the day. http://www.anzctr.org.au/.

Full Text Available Introduction GP88 (PC-Cell Derived Growth Factor, progranulin is a glycoprotein overexpressed in breast tumors and involved in their proliferation and survival. Since GP88 is secreted, an exploratory study was established to compare serum GP88 level between breast cancer patients (BC and healthy volunteers (HV. Methods An IRB approved prospective study enrolled 189 stage 1–4 BC patients and 18 HV. GP88 serum concentration was determined by immunoassay. Results Serum GP88 level was 28.7+ 5.8 ng/ml in HV and increased to 40.7+ 16.0 ng/ml ( P = 0.007 for stage 1-3 and 45.3 +23.3 ng/ml ( P = 0.0007 for stage 4 BC patients. There was no correlation between the GP88 level and BC characteristics such as age, race, tumor grade, ER, PR and HER-2 expression. Conclusion These data suggest that serial testing of serum GP88 levels may have value as a circulating biomarker for detection, monitoring and follow up of BC.

High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m 2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m 2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

Controversy persists regarding the perioperative management of clopidogrel among patients undergoing carotid endarterectomy (CEA). This study examined the effect of preoperative dual antiplatelet therapy (aspirin and clopidogrel) on in-hospital CEA outcomes. Patients undergoing CEA in the Vascular Quality Initiative were analyzed (2003-2014). Patients on clopidogrel and aspirin (dual therapy) were compared with patients taking aspirin alone preoperatively. Study outcomes included reoperation for bleeding and thrombotic complications defined as transient ischemic attack (TIA), stroke, or myocardial infarction. Secondary outcomes were in-hospital death and composite stroke/death. Univariate and multivariable analyses assessed differences in demographics and operative factors. Propensity score-matched cohorts were derived to control for subgroup heterogeneity. Of 28,683 CEAs, 21,624 patients (75%) were on aspirin and 7059 (25%) were on dual therapy. Patients on dual therapy were more likely to have multiple comorbidities, including coronary artery disease (P < .001), congestive heart failure (P < .001), and diabetes (P < .001). Patients on dual therapy were also more likely to have a drain placed (P < .001) and receive protamine during CEA (P < .001). Multivariable analysis showed that dual therapy was independently associated with increased reoperation for bleeding (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.20-2.42; P = .003) but was protective against TIA or stroke (OR, 0.61; 95% CI, 0.43-0.87; P = .007), stroke (OR, 0.63; 95% CI, 0.41-0.97; P = .03), and stroke/death (OR, 0.66; 95% CI, 0.44-0.98; P = .04). Propensity score matching yielded two groups of 4548 patients and showed that patients on dual therapy were more likely to require reoperation for bleeding (1.3% vs 0.7%; P = .004) but less likely to suffer TIA or stroke (0.9% vs 1.6%; P = .002), stroke (0.6% vs 1.0%; P = .04), or stroke/death (0.7% vs 1.2%; P = .03).

An increase of the serum PSA-level is a sensitive in vitro marker for recurrent prostate cancer. However, it remains difficult to differentiate between local, regional or distant recurrent disease. The aim of this study was to assess the relationship between the detection rate of [ 11 C]Choline-PET/CT and the serum PSA-level in patients with a biochemical recurrence of prostate cancer with the view towards localisation of recurrent disease. Sixty-three patients (mean age, 68.8 ± 6.9; range, 45-83 years) with biochemical recurrence after primary therapy for prostate cancer were included in the analysis. Mean PSA-levels were 5.9 ± 9.7 ng/ml (range, 0.2-39 ng/ml; median, 2.15). Of the 63 patients, 17 were under anti-androgen therapy at the time of [ 11 C]Choline PET/CT. Patients underwent a [ 11 C]Choline-PET/CT study after injection of 656 ± 119 MBq [ 11 C]Choline on a Sensation 16 Biograph PET/CT scanner. Of the 63 patients, 35 (56%) showed a pathological [ 11 C]Choline uptake. The detection rate of [ 11 C]Choline-PET/CT showed a relationship with the serum PSA-level: The detection rate was 36% for a PSA-value 11 C]Choline-PET/CT (p = 0.374). As an important result our study shows that even for PSA-values 11 C]Choline-PET/CT is 36%. Furthermore, the detection rate of [ 11 C]Choline-PET/CT shows a positive relationship with serum PSA-levels in patients with biochemical recurrence of prostate cancer after primary therapy. Therefore, in these patients, [ 11 C]Choline PET/CT allows not only to diagnose but also to localise recurrent disease with implications on disease management (localised vs systemic therapy).

Levels of sCD30 represent a biomarker for early outcome in kidney transplantation. The purpose of this study was to determine the role of sCD30 levels for prediction of graft loss in the late post-transplant period. Sera were collected immediately pre-transplant and yearly thereafter for up to 5-year post-transplant in 37 primary renal transplant recipients. Levels of serum sCD30 were tested using a fluorescent microsphere assay. Levels of sCD30 significantly decreased after transplantation and remained normal in 34 patients without graft loss up to 5-year post-transplant. Elevated levels of serum sCD30 preceded the increase of serum creatinine in patients with subsequent graft loss. Elevated levels of serum sCD30 post-transplant might be a marker for predicting subsequent graft loss in the post-transplant period.

Full Text Available Abstract Background The implementation of gene therapy for the treatment of pituitary tumors emerges as a promising complement to surgery and may have distinct advantages over radiotherapy for this type of tumors. Up to now, suicide gene therapy has been the main experimental approach explored to treat experimental pituitary tumors. In the present study we assessed the effectiveness of insulin-like growth factor I (IGF-I gene therapy for the treatment of estrogen-induced prolactinomas in rats. Results Female Sprague Dawley rats were subcutaneously implanted with silastic capsules filled with 17-β estradiol (E2 in order to induce pituitary prolactinomas. Blood samples were taken at regular intervals in order to measure serum prolactin (PRL. As expected, serum PRL increased progressively and 23 days after implanting the E2 capsules (Experimental day 0, circulating PRL had undergone a 3–4 fold increase. On Experimental day 0 part of the E2-implanted animals received a bilateral intrapituitary injection of either an adenoviral vector expressing the gene for rat IGF-I (RAd-IGFI, or a vector (RAd-GFP expressing the gene for green fluorescent protein (GFP. Seven days post vector injection all animals were sacrificed and their pituitaries morphometrically analyzed to evaluate changes in the lactotroph population. RAd-IGFI but not RAd-GFP, induced a significant fall in serum PRL. Furthermore, RAd-IGFI but not RAd-GFP significantly reversed the increase in lactotroph size (CS and volume density (VD induced by E2 treatment. Conclusion We conclude that IGF-I gene therapy constitutes a potentially useful intervention for the treatment of prolactinomas and that bioactive peptide gene delivery may open novel therapeutic avenues for the treatment of pituitary tumors.

We present a case of a 55-year-old male with a toxic nodule who was treated with RAI. After therapy, the patient’s serum free triiodothyronine (fT3 and free thyroxine (fT4 levels gradually increased. Antithyroid peroxidase (TPOAb, antithyroglobulin (TgAb and TSH-receptor antibodies (TRAb were also positive. Thyroid scintigraphy revealed diffuse intense uptake after four months of RAIT. Radiation-induced GD should be considered in patients with aggravated hyperthyroidism 3-4 months after therapy.

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

Creatinine (Cr) has been implicated as an independent predictor of hypertension and exercise has been reported as adjunct therapy for hypertension. The purpose of the present study was to investigate the effect of continuous training programme on blood pressure and serum creatinine concentration in black African subjects with hypertension. Three hundred and fifty seven male patients with mild to moderate (systolic blood pressure [SBP] between 140-180 & diastolic blood pressure [DBP] between 90-109 mmHg) essential hypertension were age matched and randomly grouped into continuous & control groups. The continuous group involved in an 8 weeks continuous training (60-79% HR reserve) of between 45 minutes to 60 minutes, 3 times per week, while the control group remain sedentary. SBP, DBP, VO2max, serum Cr, body mass index (BMI), waist hip ratio (WHR) and percent (%) body fat. Analysis of covariance (ANCOVA) and Pearson correlation tests were used in data analysis. Findings of the study revealed significant decreased effects of continuous training programme on SBP, DBP, Cr, BMI, WHR, % body fat and significant increase in VO2max at pexercise training as a multi-therapy in the down regulation of blood pressure, serum Cr, body size and body fat in hypertension.

Full Text Available Aim of the study: To evaluate semen parameters and to assess serum FSH, LH, Testosterone (T concentrations before and 12 weeks after intravenous iron therapy (800-1200 mg elemental iron therapy - IVI in adults with iron-deficiency anemia (IDA. Materials and Methods: We studied 11 eugonadal adults with IDA, aged 40 ± 5 years, due to defective intake of iron. Anemia was diagnosed when hemoglobin (Hb was equal or below 10 g/dl. Serum iron, total iron-binding capacity (TIBC and ferritin concentrations confirmed the diagnosis of IDA. Basal serum concentrations of FSH, LH, and T were measured. Semen parameters were evaluated before and 6-7 weeks after IVI therapy. Results: After IVI therapy and correction of anemia, a significant increase of Hb from 8.1 ± 1.17 g/dL to 13.1 ± 0.7 g/dL was observed and was associated with an increase of T (from 12.22 ± 1.4 nmol/L to 15.9 ± 0.96 nmol/L; P < 0.001, FSH (from 2.82 ± 0.87 to 3.82 ± 1.08 IU/L; P = 0.007, and LH (from 2.27 ± 0.9 to 3.82 ± 1.5 IU/L; P = 0.0002. Total sperm count (TSC increased significantly from 72 ± 17.5 million/ml to 158 ± 49 million/mL (P < 0.001, rapid progressive sperm motility (RPM increased from 22 ± 9.4 to 69 ± 30 million/ml (P < 0.001, and sperms with normal morphology (NM increased from 33 ± 5 to 56 ± 7 million/ml (P < 0.001. Increment in Hb concentration was correlated significantly with LH, FSH, and T concentrations after IVI (r = 0.69 and r = 0.44, r = 0.75, respectively; P < 0.01. The increment in serum T was correlated significantly with increments in the TSC and total sperm motility and RPM (r = 0.66, 0.43, and 0.55, respectively; P < 0.001 but not with gonadotrophin levels. Conclusion: Our study proved for the first time, to our knowledge, that correction of IDA with IVI is associated with significant enhancement of sperm parameters and increased concentrations of serum LH, FSH, and T. These effects on spermatogenesis are reached by an unknown mechanism and
