    Serum corticosteroid levels are routinely measured as markers of stress in wild animals. However, corticosteroid levels rise rapidly in response to the acute stress of capture and restraint for sampling, limiting its use as an indicator of chronic stress. We hypothesized that serum corticosteroid binding globulin (CBG), the primary transport protein for corticosteroids in circulation, may be a better marker of the stress status prior to capture in grizzly bears (Ursus arctos). To test this, a full-length CBG cDNA was cloned and sequenced from grizzly bear testis and polyclonal antibodies were generated for detection of this protein in bear sera. The deduced nucleotide and protein sequences were 1218 bp and 405 amino acids, respectively. Multiple sequence alignments showed that grizzly bear CBG (gbCBG) was 90% and 83% identical to the dog CBG nucleotide and amino acid sequences, respectively. The affinity purified rabbit gbCBG antiserum detected grizzly bear but not human CBG. There were no sex differences in serum total cortisol concentration, while CBG expression was significantly higher in adult females compared to males. Serum cortisol levels were significantly higher in bears captured by leg-hold snare compared to those captured by remote drug delivery from helicopter. However, serum CBG expression between these two groups did not differ significantly. Overall, serum CBG levels may be a better marker of chronic stress, especially because this protein is not modulated by the stress of capture and restraint in grizzly bears.

    New World primates have exceptionally high plasma levels of cortisol and other steroid hormones when compared with humans and other primates. It has been suggested that this difference can be explained by either low affinity or concentration of cellular steroid receptors. We have assessed cortisol availability in serum from several species of New and Old World primates under physiological conditions (whole serum at 37 degrees C). Measurements were made of total and free cortisol, corticosteroid-binding globulin (CBG) binding capacity and affinity for cortisol, distribution of cortisol in serum, and its binding to albumin. In agreement with earlier reports, plasma free cortisol levels in Old World primates, prosimians, and humans range from 10-300 nM. However, very high total plasma cortisol together with low CBG binding capacity and affinity result in free cortisol concentrations of 1-4 microM in some New World primates (squirrel monkey and marmosets) but not in others such as the titi and capuchin. In squirrel monkeys, free cortisol levels are far greater than might be predicted from the affinity of the glucocorticoid receptor estimated in cultured skin fibroblasts. In addition to low affinity, CBG from squirrel monkeys and other New World primates exhibits differences in electrophoretic mobility and sedimentation behavior in sucrose density ultracentrifugation, suggestive of a molecular weight that is approximately twice that of CBG from other species. Together with other data these results indicate that the apparent glucocorticoid resistance found in New World primates is a complex phenomenon that is not easily explained by present concepts of glucocorticoid action.

  3. Inhibition of corticosteroid-binding globulin gene expression by glucocorticoids involves C/EBPβ.

    Full Text Available Corticosteroid-binding globulin (CBG, a negative acute phase protein produced primarily in the liver, is responsible for the transport of glucocorticoids (GCs. It also modulates the bioavailability of GCs, as only free or unbound steroids are biologically active. Fluctuations in CBG levels therefore can directly affect GC bioavailability. This study investigates the molecular mechanism whereby GCs inhibit the expression of CBG. GCs regulate gene expression via the glucocorticoid receptor (GR, which either directly binds to DNA or acts indirectly via tethering to other DNA-bound transcription factors. Although no GC-response elements (GRE are present in the Cbg promoter, putative binding sites for C/EBPβ, able to tether to the GR, as well as HNF3α involved in GR signaling, are present. C/EBPβ, but not HNF3α, was identified as an important mediator of DEX-mediated inhibition of Cbg promoter activity by using specific deletion and mutant promoter reporter constructs of Cbg. Furthermore, knockdown of C/EBPβ protein expression reduced DEX-induced repression of CBG mRNA, confirming C/EBPβ's involvement in GC-mediated CBG repression. Chromatin immunoprecipitation (ChIP after DEX treatment indicated increased co-recruitment of C/EBPβ and GR to the Cbg promoter, while C/EBPβ knockdown prevented GR recruitment. Together, the results suggest that DEX repression of CBG involves tethering of the GR to C/EBPβ.

    Corticosteroid binding globulin (CBG) is a glycoprotein synthesized in liver and secreted in the blood where it binds with a high affinity but low capacity glucocorticoid hormones, cortisol in humans and corticosterone in laboratory rodents. In mammals, 95% of circulating glucocorticoids are bound to either CBG (80%) or albumin (15%) and only the 5% free fraction is able to enter the brain. During stress, the concentration of glucocorticoids rises significantly and the free fraction increases even more because CBG becomes saturated. However, glucocorticoids unbound to CBG are cleared from the blood more quickly. Our studies on mice totally devoid of CBG (Cbg k.o.) showed that during stress these mutant mice display a lower rise of glucocorticoids than the wild-type controls associated with altered emotional reactivity. These data suggested that CBG played a role in the fast actions of glucocorticoids on behavior. Further analyses demonstrated that stress-induced memory retrieval impairment, an example of the fast action of glucocorticoids on the brain is abolished in the Cbg k.o. mice. This effect of stress on memory retrieval could be restored in the Cbg k.o. mice by infusing corticosterone directly in the hippocampus. The mechanisms explaining these effects involved an increased clearance but no difference in corticosterone production. Thus, CBG seems to have an important role in maintaining in blood a glucocorticoid pool that will be able to access the brain for the fast effects of glucocorticoids.

    Inflammatory pathways are increasingly recognized to be tightly associated with insulin resistance in humans. The promoter region of the adiponectin gene--Apm1--encompasses consensus sequences for glucocorticosteroid receptor responsive element. Dexamethasone induced downregulation of adiponectin secretion in vitro, whereas prednisolone administration increased circulating adiponectin concentrations. As previous studies have demonstrated an inverse relationship between corticosteroid-binding globulin (CBG), body mass index, and insulin resistance, we studied whether CBG could explain cortisol-to-adiponectin relationship. One hundred twenty-two healthy subjects were enrolled in a cross-sectional study. Plasma CBG and serum cortisol concentration were measured by radioimmunoassay. The cortisol-to-CBG ratio was used to calculate free cortisol. An RIA kit (Linco Research, St Louis, MO) was used to measure adiponectin levels. Insulin resistance was calculated using the homeostatis model of assessment (HOMA) value. Circulating adiponectin was associated with serum CBG ( r = 0.38, P fasting cortisol ( P = .019) contributed to 14% and 4%, respectively, of CBG variance. In summary, circulating adiponectin, CBG concentration, and fasting cortisol were significantly interrelated in healthy subjects. A significant sexual dimorphism exists in this association.

    In the search for biological basis of robustness, this study aimed (i) at the determination of the heritability of the cortisol response to ACTH in juvenile pigs, using restricted maximum likelihood methodology applied to a multiple trait animal model, and (ii) at the study of the relationships between basal and stimulated cortisol levels with corticosteroid-binding globulin (CBG), IGF-I and haptoglobin, all important players in glucose metabolism and production traits. At 6 weeks of age, 298 intact male and female piglets from 30 litters (30 dams and 30 boars) were injected with 250 µg ACTH(1-24) (Synacthen). Blood was taken before ACTH injection to measure basal levels of cortisol, glucose, CBG, IGF-I and haptoglobin, and 60 min later to measure stimulated cortisol levels and glucose. Cortisol increased 2.8-fold after ACTH injection, with a high correlation between basal and stimulated levels (phenotypic correlation, r p=0.539; genetic correlation, r g=0.938). Post-ACTH cortisol levels were highly heritable (h 2=0.684) and could therefore be used for genetic selection of animals with a more reactive hypothalamic-pituitary-adrenocortical axis. CBG binding capacity correlated with cortisol levels measured in basal conditions in males only. No correlation was found between CBG binding capacity and post-ACTH cortisol levels. Basal IGF-I concentration was positively correlated with BW at birth and weaning, and showed a high correlation with CBG binding capacity with a strong sexual dimorphism, the correlation being much higher in males than in females. Basal haptoglobin concentrations were negatively correlated with CBG binding capacity and IGF-I concentrations. Complex relationships were also found between circulating glucose levels and these different variables that have been shown to be related to glucose resistance in humans. These data are therefore valuable for the genetic selection of animals to explore the consequences on production and robustness traits, but

  7. Emerging Role of Corticosteroid Binding Globulin in Glucocorticoid-driven Metabolic Disorders

    Full Text Available Glucocorticoid hormones (GCs are critical for survival since they ensure energy supply necessary to the body in an ever challenging environment. GCs are known to act on appetite, glucose metabolism, fatty acid metabolism and storage. However, in order to be beneficial to the body, GC levels should be maintained in an optimal window of concentrations. Not surprisingly, conditions of GC excess or deficiency, e.g. Cushing’s syndrome or Addison’s disease are associated with severe alterations of energy metabolism. Corticosteroid Binding Globulin (CBG, through its high specific affinity for GCs, plays a critical role in regulating plasma GC levels. Genetic studies in various species including humans have revealed that CBG is the major factor influencing inter-individual genetic variability of plasma GC levels, both in basal and stress conditions. Some, but not all of these genetic studies have also provided data linking CBG levels to body composition. The examination of CBG-deficient mice submitted to hyperlipidic diets unveiled specific roles for CBG in lipid storage and metabolism. The importance of CBG is even more striking when animals are submitted to high-fat diet combined to chronic stress, mimicking our occidental lifestyle. An influence of CBG on appetite has not been reported but remains to be more finely analyzed. Overall, a role of CBG in GC-driven metabolic disorders is emerging in recent studies. Although subtle, the influence of CBG in these diseases could open the way to new therapeutic interventions since CBG is easily accessible in the blood.

    It has been suggested that a low grade inflammatory state could predispose for developing insulin resistance and contribute to the development of obesity and type 2 diabetes. Corticosteroid-binding globulin (CBG), the main plasma protein transport for cortisol, has been shown to be negatively regulated by insulin and IL-6, at least in vitro, suggesting that insulin resistance and inflammation may both contribute to decreasing CBG levels. In the present study we measured CBG concentrations in a human healthy population and investigated the relationships of CBG with anthropometric and biochemical markers for inflammation and/or insulin resistance. The data showed that the mean serum CBG level was significantly lower in males (n = 151) than in females (n = 113; 32.5 +/- 9.1 vs. 39.2 +/- 13.9 mg/liter; P fasting cortisol/CBG) was significantly associated with WHR (r = 0.24; P = 0.001), systolic (r = 0.18; P = 0.01) and diastolic (r = 0.19; P = 0.007) blood pressures, and HOMA value (r = 0.20; P = 0.005), but not with BMI or age. BMI (P < 0.0001), free cortisol (P = 0.003), and CBG (P = 0.009), but not WHR and age, contributed to 20%, 6%, and 8%, respectively, of HOMA variance in women in a multiple regression analysis. In this model only BMI (P < 0.0001) independently contributed to HOMA variance in men. These findings support the hypothesis that the CBG level is an interesting indicator for both insulin resistance and low grade inflammation. Whether the decrease in CBG levels is genetic by nature or directly associated to increased insulin and/or IL-6 merits further investigation. Nevertheless, because CBG has been shown to be expressed by the adipose tissue, decreased CBG could create locally increased cortisol disposal, with no change in circulating cortisol, and facilitate fat accumulation, insulin resistance, and type 2 diabetes.

    Corticosteroid-binding globulin (CBG) binds more than 90% of circulating cortisol and is a non-inhibitory member of the family of serine protease inhibitors (SERPINS) with an exposed elastase sensitive reactive centre loop (RCL). At sites of inflammation neutrophil activation can release elastase which may cleave the RCL and result in cortisol release from CBG. The RCL sequence also has two theoretical chymotrypsin cleavage sites and we used a monoclonal antibody with specificity for the RCL to investigate chymotrypsin cleavage of CBG. Here we show, for the first time, rapid chymotrypsin cleavage of the RCL of CBG, resulting in undetectable levels of intact CBG, whereas total CBG levels were unchanged. Coincident with both chymotrypsin and elastase cleavage there was an increase in the free cortisol fraction of serum to levels similar to when CBG had been inactivated by heat indicating total cortisol release from CBG. These findings demonstrate a new mechanism for cortisol release from its binding globulin.

    Full Text Available Variation in plasma levels of cortisol, an essential hormone in the stress response, is associated in population-based studies with cardio-metabolic, inflammatory and neuro-cognitive traits and diseases. Heritability of plasma cortisol is estimated at 30-60% but no common genetic contribution has been identified. The CORtisol NETwork (CORNET consortium undertook genome wide association meta-analysis for plasma cortisol in 12,597 Caucasian participants, replicated in 2,795 participants. The results indicate that <1% of variance in plasma cortisol is accounted for by genetic variation in a single region of chromosome 14. This locus spans SERPINA6, encoding corticosteroid binding globulin (CBG, the major cortisol-binding protein in plasma, and SERPINA1, encoding α1-antitrypsin (which inhibits cleavage of the reactive centre loop that releases cortisol from CBG. Three partially independent signals were identified within the region, represented by common SNPs; detailed biochemical investigation in a nested sub-cohort showed all these SNPs were associated with variation in total cortisol binding activity in plasma, but some variants influenced total CBG concentrations while the top hit (rs12589136 influenced the immunoreactivity of the reactive centre loop of CBG. Exome chip and 1000 Genomes imputation analysis of this locus in the CROATIA-Korcula cohort identified missense mutations in SERPINA6 and SERPINA1 that did not account for the effects of common variants. These findings reveal a novel common genetic source of variation in binding of cortisol by CBG, and reinforce the key role of CBG in determining plasma cortisol levels. In turn this genetic variation may contribute to cortisol-associated degenerative diseases.

    Cortisol bound to corticosteroid binding globulin (CBG) contributes up to 90% of the total cortisol concentration in circulation. Therefore, changes in the binding kinetics of cortisol to CBG can potentially impact on the concentration of free cortisol, the only form that is responsible for the physiological function of the hormone. When CBG is cleaved into elastase-cleaved CBG (eCBG) by the activity of neutrophil elastase, its affinity for cortisol is reduced. Therefore, when eCBG coexists with intact CBG (iCBG) in plasma, the calculation of free cortisol concentration based on the formulae that considers only one CBG pool with the same affinity for cortisol may be inappropriate. In this study, we developed in vivo and in vitro models of cortisol partitioning which considers two CBG pools, iCBG and eCBG, with different affinities for cortisol, and deduce a new formula for calculating plasma free cortisol concentration. The formula provides better estimates of free cortisol concentration than previously used formulae when measurements of the concentrations of the two CBG forms are available. The model can also be used to estimate the affinity of CBG and albumin for cortisol in different clinical groups. We found no significant difference in the estimated affinity of CBG and albumin for cortisol in normal, sepsis and septic shock groups, although free cortisol was higher in sepsis and septic shock groups. The in vivo model also demonstrated that the concentration of interstitial free cortisol is increased locally at a site of inflammation where iCBG is cleaved to form eCBG by the activity of elastase released by neutrophils. This supports the argument that the cleavage of iCBG at sites of inflammation leads to more lower-affinity eCBG and may be a mechanism that permits the local concentration of free cortisol to increase at these sites, while allowing basal free cortisol concentrations at other sites to remain unaffected.

    We aimed at demonstrating that corticosteroid binding globulin (CBG), a plasma glycoprotein binding glucocorticoids with high affinity in blood, endorses a major role under stress conditions by regulating free glucocorticoid access to the brain and thereby influences glucocorticoid-dependent behaviors. Hence, we compared CBG-deficient mice (Cbg-/-) and their controls (Cbg+/+) in a specific memory task, i.e. the delayed alternation behavior, requiring memory retrieval both under stress and nonstress conditions and previously shown to be dependent on hippocampal glucocorticoid levels. Our results evidence that Cbg-/- mice, unlike controls, remain insensitive to stress applied before memory retrieval. Furthermore, under stress conditions, we observed a blunted surge of corticosterone (CORT) in plasma and no free CORT rise in the hippocampus of Cbg-/-. Moreover, intrahippocampal infusion of CORT through implanted cannulae was used to mimic stress CORT rise before memory retrieval. This infusion of CORT reproduced memory retrieval impairments in Cbg-/- as in Cbg+/+ controls. Finally, we provide evidence that Cbg-/- mice exhibit a normal adrenal response to stress and ACTH. Given that CBG deficiency is known to markedly impact on CORT clearance from plasma, our current article demonstrates that Cbg-/- insensitivity in memory retrieval after stress results from the blunted CORT response due to increased CORT clearance. Overall, our data suggest that the impact of CBG genetic deficiency on various behavioral patterns reported previously stems from a smaller CORT reservoir in blood. Inasmuch as CBG discloses interindividual variations, such a parameter ought to be taken into account when studying stress-induced glucocorticoid action in brain.

    Previously we found that late pregnancy total and free thyroxine (TT4, FT4) concentrations were negatively related to greater pre and/or postpartum depressive symptoms. In a much larger cohort, the current study examined whether these thyroid indices measured earlier in the third trimester (31-33 weeks) predict subsequent perinatal depression and anxiety ratings as well as syndromal depression. Thyroid-binding globulin (TBG) concentrations increase markedly during pregnancy and may be an index of sensitivity to elevated estrogen levels. TBG was examined in this study because prior findings suggest that postpartum depression is related to sensitivity to mood destabilization by elevated sex hormone concentrations during pregnancy. Our cohort was 199 euthyroid women recruited from a public health obstetrics clinic (63.8% Hispanic, 21.6% Black). After screening and blood draws for hormone measures at pregnancy weeks 31-33, subjects were evaluated during home visits at pregnancy weeks 35-36 as well as postpartum weeks 6 and 12. Evaluations included psychiatric interviews for current and life-time DSM-IV psychiatric history (M.I.N.I.-Plus), subject self-ratings and interviewer ratings for depression and anxiety (Edinburgh Postnatal Depression Scale, Montgomery-Ǻsberg Depression Rating Scale; Spielberger State-Trait Anxiety Inventory, Hamilton Anxiety Inventory), as well as a standardized interview to obtain life-time trauma history. Numerous covariates were included in all regression analyses. Trauma and major depression history were robustly significant predictors of depression and anxiety ratings over the study period when these variables were analyzed individually or in a combined model including FT4 or TBG (pdepression and anxiety ratings (pdepression history, were significant individual predictors of syndromal depression during the study period (pdepression history, FT4 and TBG generally were not significantly predictive of depression or anxiety ratings, and FT4

    We report the application of a recently developed alignment-free 3D QSAR method [Crippen,G.M., J. Comput. Chem., 16 (1995) 486] to a benchmark-type problem. The test systeminvolves the binding of 31 steroid compounds to two kinds of human carrier protein. Themethod used not only allows for arbitrary binding modes, but also avoids the problems oftraditional least-squares techniques with regard to the implicit neglect of informative outlyingdata points. It is seen that models of considerable predictive power can be obtained even witha very vague binding site description. Underlining a systematic, but usually ignored, problemof the QSAR approach, there is not one unique type of model but, rather, an entire manifoldof distinctly different models that are all compatible with the experimental information. Fora given model, there is also a considerable variation in the found binding modes, illustratingthe problems that are inherent in the need for 'correct` molecular alignment in conventional3D QSAR methods.

  3. THE EFFECTS OF COPPER AND ZINC IONS DURING THEIR BINDING WITH HUMAN SERUM γ-GLOBULIN

    Full Text Available Abstract. Conformational changes of human serum γ-globulin were studied during and after its binding with copper and zinc ions, using molecular ultrafiltration and differential spectrophotometry. The contents of nonbound metals in the filtrate were evaluated, resp., with sodium diethyl thyocarbamate and o-phenanthroline. It has been shown that copper and zinc exhibited common biological properties during their interactions with protein, but the binding differed sufficiently under similar experimental conditions. E.g., it was confirmed that copper was more active at the external sites of γ-globulin molecule, whereas zinc demonstrated tropicity for the areas of protein intraglobular compartments. The metal-binding sites have been described that differ in their parameters of interactions with cations and their spatial location within globular domains. Approaches are suggested for dynamic analysis of saturation for these differently located sites by the metal ions. We discuss the issues of altered conformational state of the γ-globulin molecule during the binding of cations, as well as potential usage of these data in clinical immunology.

    Disturbing the transport process is a crucial pathway for endocrine disrupting chemicals (EDCs) exerting disrupting endocrine function. However, this mechanism has not received enough attention compared with that of hormones receptors and synthetase. Recently, we have explored the interaction between EDCs and sex hormone-binding globulin of human (hSHBG). In this study, interactions between EDCs and sex hormone-binding globulin of eight fish species (fSHBG) were investigated by employing classification methods and quantitative structure-activity relationships (QSAR). In the modeling, the relative binding affinity (RBA) of a chemical with 17β-estradiol binding to fSHBG was selected as the endpoint. Classification models were developed for two fish species, while QSAR models were established for the other six fish species. Statistical results indicated that the models had satisfactory goodness of fit, robustness and predictive ability, and that application domain covered a large number of endogenous and exogenous steroidal and non-steroidal chemicals. Additionally, by comparing the log RBA values, it was found that the same chemical may have different affinities for fSHBG from different fish species, thus species diversity should be taken into account. However, the affinity of fSHBG showed a high correlation for fishes within the same Order (i.e., Salmoniformes, Cypriniformes, Perciformes and Siluriformes), thus the fSHBG binding data for one fish species could be used to extrapolate other fish species in the same Order.

    A simple method was developed to measure the SHBG capacities of human serum, semen and sperm cells. After suitable dilution, disintegration and addition of labelled dihydrotestosterone-1,2-3 H or testosterone-1,2-3 H, the SHBG was precipitated by the addition of saturated ammonium sulphate in a final concentration of 42.3%. The precipitate was centrifuged and the activity of the non-bound, labelled steroid was counted in an aliquot of the supernatant. Subtraction of this result from the total activity yielded the SHBG-bound steroid in microgram/100 ml or nmol/l. Examination of 52 males gave normal values of means = 13.91 nmol/l (S.E.M. = 0,746) dihydrotestosterone binding globulin (DHTBG) and means = 11.67 nmol/l (S.E.M. = 0.555) testosterone binding globulin (TBG) in serum, while the concentrations in the seminal plasma were means = 10.89 nmol/l (S.E.M. = 0,723) DHTBG and means = 8.93 nmol/l (S.E.M. = 0.625) TBG. means = 5.57 ng/mg protein (S.E.M. = 0.516) DHTBG and means = 4.91 ng/mg protein (S.E.M. = 0.440) TBG were found in the disintegrated sperm cells.

    Hormone analyses for hirsute women suggested that free testosterone was most revealing in biological effects and sex-hormone-binding globulin (SHBG) was quantitatively persuative. Presented in this paper are the measurements of testosterone, androstendion, dehydroepiandrosterone-sulfate (DHAS), SHBG, androstandiol and free androgen index (FAI) in 51 women with hirsutism. 92% of the hirsute women with elevated androgen level showed decrease in SHBG values and increase in FAI. 17 females with hirsutism revealed abnormally high androstandiol values which were highly related to the values of total and free testosterone (r = 0.78, r = 0.80, respectively). It is suggested that in clinical practice SHBG and FAI should also be measured besides testosterone and DHAS.

    Full Text Available It is well known that the reference values usually employed for endocrine biochemical measurements are those suggested by the suppliers of commercial kits despite their advice that each laboratory should set its own reference values. Our objectives were to (i determine reference ranges for serum testosterone (T and sex hormone binding globulin (SHBG appropriate to our laboratory and population, and (ii to analyze their influence on evaluating hyperandrogenemia. SHBG and T were measured, and free and bioavailable testosterone calculated, in (a 30 selected non-hyperandrogenic women, (b 87 non-selected healthy female blood donors, (c 53 women with hyperandrogenism, and (d 38 women with hyperandrogenic disorders but without biochemical hyperandrogenemia according to normal ranges suggested by the kit manufacturer. Mean serum SHBG concentrations were significantly different among all four groups. SHBG levels were significantly higher in selected normal women (group a. Using our results for this selected control group as new reference values, 12 out of 38 (31.6% women with hyperandrogenic disorders without apparent hyperandrogenemia (group d were recategorized as hyperandrogenemic. Similarly, 4 out of 63 (6.4% non-selected, normal weight, women (group b, were recategorized as hyperandrogenic. Therefore, the diagnosis of hyperandrogenemia would improve accuracy by using customized reference SHBG values instead of those suggested by the suppliers.

    Objective The prevalence of peripheral artery disease (PAD) increases with aging and is higher in persons with metabolic syndrome and diabetes. PAD is associated with adverse outcomes, including frailty and disability. The protective effect of testosterone and sex hormone binding globulin (SHBG) for diabetes in men suggests that the biological activity of sex hormones may affect PAD, especially in older populations. Methods Nine hundred and twenty-one elderly subjects with data on SHBG, testosterone (T), estradiol (E2) were selected from InCHIANTI study. PAD was defined as an Ankle-Brachial Index (ABI) <0.90. Logistic regression models adjusted for age (Model 1), age, BMI, insulin, interleukin-6, physical activity, smoking, chronic diseases including metabolic syndrome (Model 2), and a final model including also sex hormones (Model 3) were performed to test the relationship between SHBG, sex hormones and PAD. Results The mean age (± SD) of the 419 men and 502 women was 75.0 ± 6.8 years (Sixty two participants (41 men, 21 women) had ABI<0.90. Men with PAD had SHBG levels lower than men without PAD (p=0.03). SHBG was negatively and independently associated with PAD in men (p=0.028). but not in women. The relationship was however attenuated after adjusting for sex hormones (p=0.07). The E2 was not significantly associated with PAD in both men and women. In women, but not in men, T was positively associated with PAD, even after adjusting for multiple confounders, including E2 (p=0.01). Conclusions Low SHBG and high T levels are significantly and independently associated with the presence of PAD in older men and women, respectively. PMID:23102785

    The bone loss that occurs with ageng in postmenopausal women is related to a decrease in serum levels of bioavailable estrogen and testosterone, which are mainly bound to sex hormone-binding globulin (SHBG and albumin. Phytoestrogens are thought to exert hormonal effects in the body due to their structural resemblance to 17â-estradiol. The objective of this study was to evaluate the effect of isoflavone supplementation on levels of SHBG in postmenopausal women aged 47- 60 years. Methods A study of pre and post test design with controls was conducted in 70 women aged 47- 60 years. Subjects were randomly divided into 2 groups, the isoflavone group received 100 mg isoflavones/day + calcium 500 mg/day and the control group calcium 500 mg/day for 6 months. Measurement of bone mineral density was performed prior to supplementation, and serum SHBG levels before and after supplementation. Results Supplementation of isoflavones for 6 months reduced the SHBG levels by 31.1% in the isoflavone group (p=0.000, whereas supplementation of calcium for 6 months did not affect the levels of SHBG in the control group (p=0.359. Supplementation of isoflavones for 6 months reduced SHBG levels of postmenopausal women in the isoflavone group with either osteopenia (p=0.028 or osteoporosis (p=0.008. Conclusion Supplementation of isoflavones for 6 months decreased the SHBG levels of postmenopausal women in the isoflavone group with osteopenia and osteoporosis. Our findings suggest that phytoestrogens may significantly decreased SHBG levels in postmenopausal women.

    Researchers in Utrecht, the Netherlands have studied the effects of different factors, such as oral contraceptives (OCs), on sex hormone binding globulin (SHBG) levels in blood. The SHBG levels in women who continuously used OCs consisting only of .05 mg of ethinyl estradiol (EE2) rose as high as 260% + or - 25% of those in women not using OCs. Further, mean SHBG levels of women using combination OCs of EE2 and levonorgestrel were 10-60% higher than women not using OCs. SHBG levels were significantly higher than the use of a sequential OC containing decreasing amounts of EE2 and increasing amounts of levonorgestrel than those cause by use of a continuous combined OC with .03 mg and .15 mg respectively. As the dosage of EE2 increased in combination OCs with 2.5 mg lynestrenol, the SHBG increased from 20% (.05 mg EE2) to 150% (.75 mg EE2). SHBG levels after taking EE2 and cyproterone acetate increased significantly more (240%) than levels after EE2 and desogestrel (170%), or after EE2 and gestoden (140%) [p.001]. SHBG levels of women who took OCs containing only .03 mg of levonorgestrel daily decreased 35% (p.01). These levels fell by 30% in women who received 150 mg of medroxyprogesterone acetate intramuscularly every 3 months (p.001). SHBG concentrations increased when estrogens were taken orally for noncontraceptive purposes, but they did not change when they were administered percutaneously. As body weight increased the SHBG levels decreased despite hormonal status or sex. Further, the lower the fat content of one's diet the higher the SHBG levels and vice versa. SHBG levels are higher in males with flaccid lungs than they are in males with healthy lungs.

    Full Text Available CONTEXT AND OBJECTIVE: Metabolic syndrome consists of a set of factors that imply increased risk of cardiovascular diseases. The objective here was to evaluate the association between sex hormone-binding globulin (SHBG, sex hormones and metabolic syndrome among men. DESIGN AND SETTING: Retrospective analysis on data from the study "Endogenous oestradiol but not testosterone is related to coronary artery disease in men", conducted in a hospital in São Paulo. METHODS: Men (aged 40-70 who underwent coronary angiography were selected. The age, weight, height, waist circumference, body mass index and prevalence of dyslipidemia, hypertension and diabetes of each patient were registered. Metabolic syndrome was defined in accordance with the criteria of the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (NCEP-ATPIII. Serum samples were collected to assess the levels of glucose, total cholesterol, HDL-cholesterol (high density lipoprotein, triglycerides, albumin, SHBG, estradiol and total testosterone (TT. The levels of LDL-cholesterol (low density lipoprotein were calculated using Friedewald's formula and free testosterone (FT and bioavailable testosterone (BT using Vermeulen's formula. RESULTS: 141 patients were enrolled in the study. The prevalence of metabolic syndrome was significantly higher in the first SHBG tercile than in the second and third terciles. A statistically significant positive association between the SHBG and TT values was observed, but no such association was seen between SHBG, BT and FT. CONCLUSION: Low serum levels of SHBG are associated with higher prevalence of metabolic syndrome among male patients, but further studies are required to confirm this association.

    The differential availability of thyroxine (T/sub 4/) and 3,5,3'-triiodothyronine (T/sub 3/) to liver from the circulating thyroid hormone binding globulin (TBG)-bound pool suggests that the two thyroid hormones may bind to different TBG isoforms in human serum. In the present study, the binding of (/sup 125/I)T/sub 4/ and (/sup 125/I)T/sub 3/ to human serum proteins was investigated by using slab gel isoelectric focusing and chromatofocusing. In normal human male serum, (/sup 125/I)T/sub 4/ was localized to four isoforms of TBG called TBG-I, -II, -III, and -IV, with isoelectric points (pI's) of 4.30, 4.35, 4.45, and 4.55, respectively. (/sup 125/I)T/sub 3/ was localized to only two isoforms of TBG, TBG-III, and -IV, with pI's that were identical with those for (/sup 125/I)T/sub 4/. In normal female serum, (/sup 125/I)T/sub 4/ was localized to the same four isoforms of TBG as those of normal male serum, while (/sup 125/I)T/sub 3/ was localized to TBG-II, -III, -IV, and -V (pI = 4.65). In pregnant female serum, (/sup 125/I)T/sub 4/ was localized to five isoforms, whereas (/sup 125/I)T/sub 3/ was localized to four. IEF was also performed with male serum loaded with various concentrations of unlabeled T/sub 3/. The K/sub i/ values of T/sub 3/ binding to TBG-I, -II, -III, and -IV were 5.0, 2.4, 0.86, and 0.46 nM, respectively. The TBG isoforms in normal male serum were also separated by sequential concanavalin A-Sepharose affinity chromatography and the chromatofocusing (pH range of 3.5-5.0). T/sub 4/ preferentially bound to the most acidic isoforms of TBG in the pI range of 3.8-4.0, whereas the less acidic fractions (pH 4.0-4.2) bound both T/sub 4/ and T/sub 3/. In conclusion, this study shows that T/sub 4/ and T/sub 3/ do not bind to a single competitive binding site on TBG. Instead, T/sub 4/ is preferentially bound by the most acidic TBG isoforms owing to a 10-fold lower affinity of T/sub 3/ for these proteins.

    Steroid hormone-binding globulin in human serum displays different isoelectric focusing (IEF) patterns among individuals, suggesting genetic variation in the gene for this extracellular steroid carrier protein. Analysis of allele frequencies and family studies suggested the existence of two codominant alleles of the gene. Subsequent determination of the molecular basis of a variant of the gene was carried out using DNA from homozygous individuals from a single Belgian family. It was of interest to characterize other variant individuals to determine whether all variants identified by IEF phenotyping were caused by the same mutation or whether other mutations occurred in the gene in different populations. Previous studies identified Mexican subjects who were heterozygous for the variant IEF phenotype. Denaturing gradient gel electrophoresis was used to localize the mutation in these subjects and to purify the variant allele for DNA sequence analysis. The results show that the mutation in this population is identical to that identified in the Belgian family, and no other mutations were detected in the gene. These data represent the first analysis of steroid hormone-binding globulin gene variation in heterozygous subjects and further support the conclusion of biallelism of the gene worldwide. 11 refs., 2 figs., 1 tab.

    The three-dimensional model built for the 13S globulin allergen of buckwheat (Fagopyrum esculentum) consists of three protomers exhibiting the cupin motif, arranged in a homotrimer around a three-fold symmetry axis. Using the SPOT technique, 11 continuous IgE-binding epitopic peptides were characterized on the molecular surface of the 13S globulin allergen of buckwheat. Except for one of them, they all correspond to well exposed regions containing electropositiveley and/or electronegatively charged residues, which cover up to 40% of the molecular surface of the allergen. Some of these epitopes come in close contact to probably create more extended discontinuous epitopes, especially those located on the edge of the 13S globulin homotrimer. Half of the identified epitope peptides remain unaltered in a core structure protected against hydrolysis by digestive proteases and are thus assumed to promote the allergenicity of the 13S globulin. In addition, a few of these epitopes coincide with sequential IgE-binding epitopes previously characterized in soybean 11S globulins, that could account for the IgE-binding cross-reactions observed between soybean and buckwheat in Western blot experiments.

    Full Text Available OBJECTIVES: Variations in sex hormones and the calcium balance can influence bone health in men. The present study aimed to examine the relationship between the calcaneal speed of sound and biochemical determinants of bone mass, such as sex hormones, parathyroid hormones and serum calcium. METHODS: Data from 549 subjects from the Malaysian Aging Male Study, which included Malay and Chinese men aged 20 years and older residing in the Klang Valley, were used for analysis. The subjects' calcaneal speed of sound was measured, and their blood was collected for biochemical analysis. Two sets of multiple regression models were generated for the total/bioavailable testosterone and estradiol to avoid multicollinearity. RESULTS: The multiple regression results revealed that bioavailable testosterone and serum total calcium were significant predictors of the calcaneal speed of sound in the adjusted model. After adjustment for ethnicity and body mass index, only bioavailable testosterone remained significant; the total serum calcium was marginally insignificant. In a separate model, the total testosterone and sex hormone-binding globulin were significant predictors, whereas the total serum calcium was marginally insignificant. After adjustment for ethnicity and body mass index (BMI, the significance persisted for total testosterone and SHBG. After further adjustment for age, none of the serum biochemical determinants was a significant predictor of the calcaneal speed of sound. CONCLUSION: There is a significant age-dependent relationship between the calcaneal speed of sound and total testosterone, bioavailable testosterone and sex hormone-binding globulin in Chinese and Malay men in Malaysia. The relationship between total serum calcium and calcaneal speed of sound is ethnicity-dependent.

    We present an unusual variant of T(4)-binding globulin (TBG) found in a family from Allentown, Pennsylvania (TBG-AT). The heterozygous proposita presented serum total T(4) and TBG levels ranging from low to normal. TBG gene sequencing revealed a C-to-T substitution in codon -2 (CAC to TAC) leading to the substitution of the normal histidine by a tyrosine within the signal peptide. No mutation within the mature peptide was found. Allele-specific PCR confirmed the H(-2)Y mutation in the propositas mother and son. T(4)-binding analysis of TBG in serum from the proposita and son showed normal affinity but reduced capacity when compared with the unaffected father. Heat stability and isoelectric focusing of TBG-AT were normal. In vitro expression of a recombinant TBG-AT in Xenopus oocytes revealed a diminished secretory efficiency and confirmed the normal binding affinity and heat stability of the small amount of secreted TBG-AT. This study has defined impaired cotranslational processing as a hitherto unrecognized cause of hereditary TBG deficiency.

    Serum vitamin D binding protein (DBP, also known as Gc-globulin) is a multifunctional protein capable of binding both vitamin D metabolites and actin. DBP can be visualized when analyzed by polyacrylamide gel electrophoresis followed by staining. Confirmation of its identity had previously required immunoprecipitation with specific anti-DBP antisera or occupancy of the protein with radioactive vitamin D sterols. We present studies showing that preincubation of G-actin with mammalian sera produced a discernible DBP protein band shift on native gel electrophoresis. Addition of DNaseI, a 33-kDa intracellular protein with an avid actin-binding site, to the incubations resulted in a supershift of DBP-actin complexes to an even more cathodal region of the gels. Following incubations with human, rat, and murine sera the same actin shift occurred as did the actin plus DNaseI supershift. The migrations of each complex were correlated with purified DBP migrations under identical conditions. It was confirmed that the supershifted bands contained DBP by Western blotting and detection of DBP by binding of 25-OH[3H]D3. After intravenous G-actin injections into living mice, a serum DBP-actin complex could be detected on native gels as the uncomplexed DBP band decreased in intensity. This simple, direct-staining technique appears to be suitable for identifying DBP/Gc phenotypes in human populations as well as for semiquantitatively monitoring the plasma actin-scavenger system in vivo in animal models or in human diseases.

    Context: SHBG is known as the major sex steroid binding protein in plasma, and it regulates the bioavailability of both T and estradiol levels required for effects on target tissues. We identified a man with an undetectable SHBG concentration in combination with low total T. He presented with a 7-ye

    AIM To assess potential contributions of biliary IgA for crystal agglomeration into gallstones, we visualized cholesterol crystal binding of biliary IgA.METHODS Crystal-binding biliary proteins were extracted from human gallbladder bile using lectin affinity chromatography. Biliary IgA was isolated from the bound protein fraction by immunoaffinity chromatography. Pure cholesterol monohydrate crystals were incubated with biliary IgA and fluoresceine isothiocyanate (FITC)-conjugated anti-lgA at 37C. Samples were examined under polarizing and fluorescence light microscopy with digital image processing.RESULTS Binding of biliary IgA to cholesterol monohydrate crystals could be visualized with FITC-conjugated anti-lgA antibodies. Peak fluorescence occurred at crystal edges and dislocations. Controls without biliary IgA or with biliary IgG showed no significant fluorescence.CONCLUSION Fluorescence light microscopy provided evidence for cholesterol crystal binding of biliary IgA. Cholesterol crystalbinding proteins like IgA might be important mediators of crystal agglomeration and growth of cholesterol gallstones by modifying the evolving crystal structures in vivo.

    Early developmental experiences play an important role in development of the adult phenotype. We investigated the effects of neonatal handling on the hypothalamic-pituitary-adrenal axis in a free-living avian species, the American kestrel (Falco sparverius). In the handled group (H), kestrel chicks were handled for 15 min/day from hatching until 26 days of age, after which time blood samples were collected for analysis of adrenal responsiveness and corticosterone binding globulin (CBG) levels. The non-handled control group (NH) was left undisturbed until 26 days of age when blood samples were collected and analyzed as above. Handled and NH kestrels did not differ in body condition index. Both total corticosterone (CORT) and CBG capacity were dampened significantly in H kestrels. However, free CORT did not differ between the two groups. In addition, hormone challenges of corticotropin releasing factor and adrenocorticotropin hormone were compared to saline injections to determine if the pituitary or the adrenal glands, respectively, were rendered more or less sensitive by handling. There was no difference in the responsiveness of H and NH kestrels to either hormone challenge. It is clear from these data that handling had an affect on fledgling phenotypic development, although whether the effects are permanent or ephemeral is unknown. Copyright © 2011 Elsevier Inc.

    The association between sex hormones and sex hormone binding globin (SHBG) with vertebral fractures in men is not well studied. In these analyses, we determined whether sex hormones and SHBG were associated with greater likelihood of vertebral fractures in a prospective cohort study of community dwelling older men. We included data from participants in MrOS who had been randomly selected for hormone measurement (N=1463, including 1054 with follow-up data 4.6years later). Major outcomes included prevalent vertebral fracture (semi-quantitative grade≥2, N=140, 9.6%) and new or worsening vertebral fracture (change in SQ grade≥1, N=55, 5.2%). Odds ratios per SD decrease in sex hormones and per SD increase in SHBG were estimated with logistic regression adjusted for potentially confounding factors, including age, bone mineral density, and other sex hormones. Higher SHBG was associated with a greater likelihood of prevalent vertebral fractures (OR: 1.38 per SD increase, 95% CI: 1.11, 1.72). Total estradiol analyzed as a continuous variable was not associated with prevalent vertebral fractures (OR per SD decrease: 0.86, 95% CI: 0.68 to 1.10). Men with total estradiol values ≤17pg/ml had a borderline higher likelihood of prevalent fracture than men with higher values (OR: 1.46, 95% CI: 0.99, 2.16). There was no association between total testosterone and prevalent fracture. In longitudinal analyses, SHBG (OR: 1.42 per SD increase, 95% CI: 1.03, 1.95) was associated with new or worsening vertebral fracture, but there was no association with total estradiol or total testosterone. In conclusion, higher SHBG (but not testosterone or estradiol) is an independent risk factor for vertebral fractures in older men.

    Oral oestrogen increases the risk of venous thromboembolism (VTE) and increases production of sex hormone-binding globulin (SHBG) in a dose-dependent manner. SHBG has been suggested to be involved in venous thromboembolism. We examined the effects of oral ultra-low-dose oestradiol on circulating levels of SHBG and coagulation parameters, and we compared the effects to those of transdermal oestradiol. Twenty women received oral oestradiol (500 μg) every day (oral ultra-low-dose group) and 20 women received a transdermal patch (50 μg) as a transdermal group. In addition, the women received dydrogesterone continuously (5 mg) except for women who underwent hysterectomy. Circulating SHBG, antithrombin III (ATIII) activity, d-dimer, thrombin-antithrombin complex and plasmin-α2 plasmin inhibitor complex were measured before and 3 months after the start of treatment. SHBG was significantly increased at 3 months in the oral ultra-low-dose group, but not in the transdermal group. However, percent changes in SHBG were not significantly different between the two groups. In both groups, ATIII was significantly decreased at 3 months. In conclusion, even ultra-low-dose oestradiol orally increases circulating SHBG level. However, the magnitude of change in SHBG caused by oral ultra-low-dose oestradiol is small and is comparable to that caused by transdermal oestradiol. Impact statement Oral oestrogen replacement therapy increases production of SHBG which may be related to increase in VTE risk. However, the effect of oral ultra-low-dose oestradiol on SHBG has not been clarified. Even ultra-low-dose oestradiol orally increases circulating SHBG levels, but the magnitude of change in SHBG caused by oral ultra-low-dose oestradiol is small and is comparable to that caused by transdermal oestradiol. VTE risk in women receiving oral ultra-low-dose oestradiol may be comparable to that in women receiving transdermal oestradiol.

    What is the impact of intentional weight loss and regain on serum androgens in women? We conducted an ancillary analysis of prospectively collected samples from a randomized controlled trial. The trial involved supervised 10% weight loss (8.5 kg on average) with diet and exercise over 4-6 months followed by supervised intentional regain of 50% of the lost weight (4.6 kg on average) over 4-6 months. Participants were randomized prior to the partial weight regain component to either continuation or cessation of endurance exercise. Analytic sample included 30 obese premenopausal women (mean age of 40 ± 5.9 years, mean baseline body mass index (BMI) of 32.9 ± 4.2 kg/m(2)) with metabolic syndrome. We evaluated sex hormone binding globulin (SHBG), total testosterone (T), free androgen index (FAI), and high molecular weight adiponectin (HMWAdp). Insulin, homeostasis model assessment (HOMA), and quantitative insulin sensitivity check index (QUICKI), and visceral adipose tissue (VAT) measured in the original trial were reanalyzed for the current analytic sample. Insulin, HOMA, and QUICKI improved with weight loss and were maintained despite weight regain. Log-transformed SHBG significantly increased from baseline to weight loss, and then significantly decreased with weight regain. LogFAI and logVAT decreased similarly and increased with weight loss followed by weight regain. No changes were found in logT and LogHMWAdp. There was no significant difference in any tested parameters by exercise between the groups. SHBG showed prominent sensitivity to body mass fluctuations, as reduction with controlled intentional weight regain showed an inverse relationship to VAT and occurred despite stable HMWAdp and sustained improvements with insulin resistance. FAI showed opposite changes to SHBG, while T did not change significantly with weight. Continued exercise during weight regain did not appear to impact these findings.

    Full Text Available Genome-wide association studies (GWAS have successfully identified common genetic variants that contribute to breast cancer risk. Discovering additional variants has become difficult, as power to detect variants of weaker effect with present sample sizes is limited. An alternative approach is to look for variants associated with quantitative traits that in turn affect disease risk. As exposure to high circulating estradiol and testosterone, and low sex hormone-binding globulin (SHBG levels is implicated in breast cancer etiology, we conducted GWAS analyses of plasma estradiol, testosterone, and SHBG to identify new susceptibility alleles. Cancer Genetic Markers of Susceptibility (CGEMS data from the Nurses' Health Study (NHS, and Sisters in Breast Cancer Screening data were used to carry out primary meta-analyses among ~1600 postmenopausal women who were not taking postmenopausal hormones at blood draw. We observed a genome-wide significant association between SHBG levels and rs727428 (joint β = -0.126; joint P = 2.09 × 10(-16, downstream of the SHBG gene. No genome-wide significant associations were observed with estradiol or testosterone levels. Among variants that were suggestively associated with estradiol (P<10(-5, several were located at the CYP19A1 gene locus. Overall results were similar in secondary meta-analyses that included ~900 NHS current postmenopausal hormone users. No variant associated with estradiol, testosterone, or SHBG at P<10(-5 was associated with postmenopausal breast cancer risk among CGEMS participants. Our results suggest that the small magnitude of difference in hormone levels associated with common genetic variants is likely insufficient to detectably contribute to breast cancer risk.

    Full Text Available Abstract Background The human Sex Hormone Binding Globulin (SHBG gene, located at 17p13.1, comprises, at least, two different transcription units regulated by two different promoters. The first transcription unit begins with the exon 1 sequence and is responsible for the production of plasma SHBG by the hepatocytes, while the second begins with an alternative exon 1 sequence, which replaces the exon 1 present in liver transcripts. Alternative exon 1 transcription and translation has only been demonstrated in the testis of transgenic mice containing an 11-kb human SHBG transgene and in the human testis. Our goal has been to further characterize the 5' end of the SHBG gene and analyze the presence of the SHBG alternative transcripts in human prostate tissue and derived cell lines. Results Using a combination of in silico and in vitro studies, we have demonstrated that the SHBG gene, along with exon 1 and alternative exon 1 (renamed here exon 1A, contains four additional alternative first exons: the novel exons 1B, 1C, and 1E, and a previously identified exon 1N, which has been further characterized and renamed as exon 1D. We have shown that these four alternative first exons are all spliced to the same 3' splice site of SHBG exon 2, and that exon 1A and the novel exon 1B can be spliced to exon 1. We have also demonstrated the presence of SHBG transcripts beginning with exons 1B, 1C and 1D in prostate tissues and cell lines, as well as in several non-prostatic cell lines. Finally, the alignment of the SHBG mammalian sequences revealed that, while exons 1C, 1D and 1E are very well conserved phylogenetically through non-primate mammal species, exon 1B probably aroused in apes due to a single nucleotide change that generated a new 5' splice site in exon 1B. Conclusion The identification of multiple transcription start sites (TSS upstream of the annotated first exon of human SHBG, and the detection of the alternative transcripts in human prostate

    This study determines the effect of atrazine and fenitrothion no-observed-effect-levels (NOEL) on the binding of corticosterone (B) to corticosterone-binding-globulin (CBG) in an amphibian and a mammal. Plasma from five cane toads and five Wistar rats was exposed to atrazine and fenitrothion at the NOEL approved for Australian fresh water residues and by the World Health Organization (WHO). The concentration required to displace 50% (IC50) of B binding to CBG was determined by a competitive microdialysis protein assay. Competition studies showed that both atrazine and fenitrothion at NOEL are able to compete with B for CBG binding sites in toad and rat plasma. The IC50 levels for atrazine in toads and rats were 0.004 nmol/l and 0.09 nmol/l respectively. In the case of fenitrothion the IC50 level found in toads was 0.007 nmol/l, and 0.025 nmol/l in rats. Plasma dilution curves showed parallelism with the curve of B, demonstrating that these agro-chemicals are competitively inhibiting binding to CBG. The displacement of B by atrazine and fenitrothion would affect the total:free ratio of B and consequently disrupt the normal stress response. This is the first time that the potential disruptive effect of atrazine and fenitrothion on B-CBG interaction at the NOELs has been demonstrated in amphibian and mammalian models.

    The effect of a 60-day period of treatment with L-T/sub 3/ (200 ..mu..g/day) was evaluated in hirsute obese women and normal controls. The obese patients were also submitted to a low calorie high protein diet. Mean initial weight significantly declined with a significant lowering of the mean DHEA-S level. There were changes in serum T/sub 3/ which rose in both obese and normal patients. Serum sex-hormone binding globulin levels at baseline studies were significantly higher in normal controls than in obese patients. At the end of the 60-day period of L-T/sub 3/ administration it was observed in both groups a 2-4 fold increase in serum SHBG levels but normal controls had significantly higher mean values than obese individuals.

    In birds, suppressed expression of stress-induced corticosterone (CORT) during pre-basic molt is generally thought to reflect a physiological trade-off in self-maintenance. And reduced CORT during breeding in extreme environments may maximize reproductive success and optimize their fitness. Highland Eurasian tree sparrows (Passer montanus) are known to express significantly higher stress-induced CORT levels during the pre-basic molt stage. Here, we show that these highland sparrows are characterized by a life history strategy of molt-breeding overlap, with higher corticosterone-binding globulin (CBG) levels favoring molt and breeding consistent with fitness optimization on the Tibetan Plateau. These unique behavioral and physiological strategies reflect natural selection under strong evolutionary pressures in extreme high-altitude environments.

    The availability of testosterone and estradiol to Sertoli and prostate cells is dependent upon 1) the permeability properties of the blood-tubular barrier (BTB) of the testis or prostate cell membrane, and 2) sex steroid binding to plasma proteins, such as albumin or testosterone-binding globulin (TeBG). Sex steroid influx into these tissues was studied after in vivo arterial bolus injections of (/sup 3/H)testosterone or (/sup 3/H)estradiol in anesthetized rats. Both testosterone and estradiol were readily cleared across the BTB or prostate cell membrane in the absence of plasma proteins and in the presence of human pregnancy serum, in which testosterone or estradiol are 80-95% distributed to TeBG. The extravascular extraction of (/sup 3/H)TeBG across the BTB or prostate plasma membrane (73 +/- 2% (+/- SE) and 92 +/- 9%, respectively) was significantly greater than extraction of (/sup 3/H)albumin or other plasma space markers and indicative of a rapid first pass clearance of TeBG by Sertoli or prostate cells. In summary, these studies indicate that 1) testosterone and estradiol are readily cleared by Sertoli and prostate cells; 2) albumin- and TeBG-bound sex steroids represent the major circulating pool of bioavailable hormone for testis or prostate; and 3) the TeBG-sex steroid complex may be nearly completely available for influx through the BTB or prostate plasma membrane.

    A stressful event results in secretion of glucocorticoid hormones, which bind to mineralocorticoid receptors (MRs) and glucocorticoid receptors (GRs) in the hippocampus to regulate cognitive and affective responses to the challenge. MRs are already highly occupied by low glucocorticoid levels under baseline conditions, whereas GRs only become substantially occupied by stress- or circadian-driven glucocorticoid levels. Currently, however, the binding of MRs and GRs to glucocorticoid-responsive elements (GREs) within hippocampal glucocorticoid target genes under such physiological conditions in vivo is unknown. We found that forced swim (FS) stress evoked increased hippocampal RNA expression levels of the glucocorticoid-responsive genes FK506-binding protein 5 (Fkbp5), Period 1 (Per1), and serum- and glucocorticoid-inducible kinase 1 (Sgk1). Chromatin immunoprecipitation (ChIP) analysis showed that this stressor caused substantial gene-dependent increases in GR binding and surprisingly, also MR binding to GREs within these genes. Different acute challenges, including novelty, restraint, and FS stress, produced distinct glucocorticoid responses but resulted in largely similar MR and GR binding to GREs. Sequential and tandem ChIP analyses showed that, after FS stress, MRs and GRs bind concomitantly to the same GRE sites within Fkbp5 and Per1 but not Sgk1 Thus, after stress, MRs and GRs seem to bind to GREs as homo- and/or heterodimers in a gene-dependent manner. MR binding to GREs at baseline seems to be restricted, whereas after stress, GR binding may facilitate cobinding of MR. This study reveals that the interaction of MRs and GRs with GREs within the genome constitutes an additional level of complexity in hippocampal glucocorticoid action beyond expectancies based on ligand-receptor interactions.

    Full Text Available Abstract Background The sex hormone-binding globulin (SHBG is a carrier protein that modulates the bio-availability of serum sex steroid hormones, which may be involved in ovarian cancer. We evaluated whether common genetic variation in SHBG and its 3' neighbor ATP1B2, in linkage disequilibrium, is associated with the risk of epithelial ovarian cancer. Methods The study population included 264 women with ovarian carcinoma and 625 controls participating in a population-based case-control study in Poland. Five common single nucleotide polymorphisms (SNPs in SHGB and five in ATP1B2 were selected to capture most common variation in this region. Results None of the SNPs evaluated was significantly associated with ovarian cancer risk, including the putative functional SNPs SHBG D356N (rs6259 and -67G>A 5'UTR (rs1799941. However, our data were consistent with a decreased ovarian cancer risk associated with the variant alleles for these two SNPs, which have been previously associated with increased circulating levels of SHBG. Conclusion These data do not support a substantial association between common genetic variation in SHBG and ovarian cancer risk.

    Circulating levels of sex hormone-binding globulin (SHBG) are inversely associated with breast cancer risk in postmenopausal women. Three polymorphisms within the SHBG gene have been reported to affect SHBG levels, but there has been no systematic attempt to identify other such variants. We looked for associations between SHBG levels in 1,134 healthy, postmenopausal women and 11 tagging single nucleotide polymorphisms (SNP) in or around the SHBG gene. Associations between SHBG SNPs and breast cancer were tested in up to 6,622 postmenopausal breast cancer cases and 6,784 controls. Ten SNPs within or close to the SHBG gene were significantly associated with SHBG levels as was the (TAAAA)(n) polymorphism. The best-fitting combination of rs6259, rs858521, and rs727428 and body mass index, waist, hip, age, and smoking status accounted for 24% of the variance in SHBG levels (natural logarithm transformed). Haplotype analysis suggested that rs858518, rs727428, or a variant in linkage disequilibrium with them acts to decrease SHBG levels but that this effect is neutralized by rs6259 (D356N). rs1799941 increases SHBG levels, but the previously reported association with (TAAAA)(n) repeat length appears to be a consequence of linkage disequilibrium with these SNPs. One further SHBG SNP was significantly associated with breast cancer (rs6257, per-allele odds ratio, 0.88; 95% confidence interval, 0.82-0.95; P = 0.002). At least 3 SNPs showed associations with SHBG levels that were highly significant but relatively small in magnitude. rs6257 is a potential breast cancer susceptibility variant, but relationships between the genetic determinants of SHBG levels and breast cancer are complex.

    Full Text Available It is unclear whether serum adiponectin concentrations diminish linearly with increasing adiposity and, if not, which factors codetermine this association. These issues were investigated cross-sectionally in 1188 men and women, representative of middle-aged and elderly Turkish adults. Serum total adiponectin was assayed by ELISA. Serum adiponectin values in men, though declining significantly in transition from the bottom to the mid tertile of body mass index (BMI and waist circumference (WC, were similar in the two respective upper tertiles. In women, serum adiponectin concentrations were not significantly different in any tertile of these indices, were significantly correlated with BMI or WC within the low tertiles and not within the two higher tertiles. In a linear regression analysis for WC (or BMI in a subset of the sample in which serum sex hormone-binding globulin (SHBG was available and which additionally comprised adiponectin, fasting insulin and other confounders, only insulin and, in women SHBG, were significantly associated, but not adiponectin. In linear regression analyses for covariates of adiponectin in two models comprising 12 variables, insulin and SHBG concentrations were significantly associated in both genders though not BMI. Whereas in men HDL-cholesterol and CRP were covariates of adiponectin (both p<0.01, SHBG and apolipoprotein B positively associated in women (p<0.001, independent of BMI and fasting insulin levels. Conclusions: Relationship between excess adiposity and adiponectin levels is inconsistent in Turkish adults. Independently from obesity and hyperinsulinemia, serum adiponectin discloses significant relationship with inflammatory markers and HDL only in men, not in women in whom it is influenced by SHBG, with consequent attenuation of its anti-inflammatory activities.

    Full Text Available Low levels of sex hormone-binding globulin (SHBG are considered to be an indirect index of hyperinsulinemia, predicting the later onset of diabetes mellitus type 2. In the insulin resistance state and in the presence of an increased pancreatic ß-cell demand (e.g. obesity both absolute and relative increases in proinsulin secretion occur. In the present study we investigated the correlation between SHBG and pancreatic ß-cell secretion in men with different body compositions. Eighteen young men (30.0 ± 2.4 years with normal glucose tolerance and body mass indexes (BMI ranging from 22.6 to 43.2 kg/m2 were submitted to an oral glucose tolerance test (75 g and baseline and 120-min blood samples were used to determine insulin, proinsulin and C-peptide by specific immunoassays. Baseline SHBG values were significantly correlated with baseline insulin (r = -0.58, P28 kg/m2, N = 8 and nonobese (BMI £25 kg/m2, N = 10 groups, significantly lower levels of SHBG were found in the obese subjects. The obese group had significantly higher baseline proinsulin, C-peptide and 120-min proinsulin and insulin levels. For the first time using a specific assay for insulin determination, a strong inverse correlation between insulinemia and SHBG levels was confirmed. The finding of a strong negative correlation between SHBG levels and pancreatic ß-cell secretion, mainly for the 120-min post-glucose load proinsulin levels, reinforces the concept that low SHBG levels are a suitable marker of increased pancreatic ß-cell demand.

    Full Text Available Abstract Background Sex hormone-binding globulin (SHBG levels and sex hormones have been implicated in the pathogenesis of type 2 diabetes and cardiovascular diseases. As fatty liver has been suggested to be a major determinant of SHBG levels, we examined whether the associations of SHBG and testosterone with diabetes were independent of fatty liver. Methods We conducted a case–control study that included 300 diabetes cases (215 men and 85 women and 300 matched controls from the Saku cohort study. Diabetes was defined by either fasting plasma glucose levels ≥126 mg/dL, 2-h post-load glucose levels ≥200 mg/dL after a 75 g oral glucose tolerance test, or diabetes diagnosed by physicians. We fitted conditional logistic regression models to examine the associations between SHBG and total testosterone levels with diabetes by sex. To evaluate the impact of fatty liver, we used the fatty liver index (FLI, a validated measure derived from serum triglyceride levels, body mass index (BMI, waist circumference, and γ-glutamyltransferase levels. Results After adjusting for age, family history of diabetes, smoking, physical activity, BMI, and FLI, SHBG levels were inversely associated with diabetes among women (odds ratio [OR] comparing the highest with the lowest quartiles, 0.13 [95% confidence interval {CI}, 0.02–0.96], but not among men. Similar patterns were observed in a subgroup analysis restricted to postmenopausal women"(OR, 0.12 [95% CI, 0.01–1.17]. In contrast, testosterone levels were inversely associated with diabetes among men (OR, 0.45 [95% CI, 0.23–0.89], but not among women. Conclusions Our findings suggest that SHBG in women and testosterone in men may be inversely associated with diabetes.

    Full Text Available Abstract Background Findings from observational studies suggest that sex hormone-binding globulin (SHBG and endogenous sex hormones may be mediators of the putative relation between coffee consumption and lower risk of type 2 diabetes. The objective of this study was to evaluate the effects of caffeinated and decaffeinated coffee on SHBG and sex hormone levels. Findings After a two-week run-in phase with caffeine abstention, we conducted an 8-week parallel-arm randomized controlled trial. Healthy adults (n = 42 were recruited from the Boston community who were regular coffee consumers, nonsmokers, and overweight. Participants were randomized to five 6-ounce cups of caffeinated or decaffeinated instant coffee or water (control group per day consumed with each meal, mid-morning, and mid-afternoon. The main outcome measures were SHBG and sex hormones [i.e., testosterone, estradiol, dehydroepiandrosterone sulfate]. No significant differences were found between treatment groups for any of the studied outcomes at week 8. At 4 weeks, decaffeinated coffee was associated with a borderline significant increase in SHBG in women, but not in men. At week 4, we also observed several differences in hormone concentrations between the treatment groups. Among men, consumption of caffeinated coffee increased total testosterone and decreased total and free estradiol. Among women, decaffeinated coffee decreased total and free testosterone and caffeinated coffee decreased total testosterone. Conclusions Our data do not indicate a consistent effect of caffeinated coffee consumption on SHBG in men or women, however results should be interpreted with caution given the small sample size. This is the first randomized trial investigating the effects of caffeinated and decaffeinated coffee on SHBG and sex hormones and our findings necessitate further examination in a larger intervention trial.

    Background Circulating levels of sex hormone-binding globulin (SHBG) are inversely associated with breast cancer risk in post-menopausal women. Three polymorphisms within the SHBG gene have been reported to affect SHBG levels, but there has been no systematic attempt to identify other such variants. Methods We looked for associations between SHBG levels in 1134 healthy, postmenopausal women and 11 tagging single nucleotide polymorphisms (SNPs) in or around the SHBG gene. Associations between SHBG SNPs and breast cancer were tested in up to 6622 post-menopausal breast cancer cases and 6784 controls. Results Ten SNPs within or close to the SHBG gene were significantly associated with SHBG levels, as was the (TAAAA)n polymorphism. The best-fitting combination of rs6259, rs858521, rs727428 and body mass index, waist, hip, age and smoking status accounted for 24% of the variance in SHBG levels (natural logarithm transformed). Haplotype analysis suggested that rs858518, rs727428 or a variant in linkage disequilibrium with them, acts to decrease SHBG levels, but that this effect is neutralised by rs6259 (D356N). rs1799941 increases SHBG levels, but the previously reported association with (TAAAA)n repeat length appears to be a consequence of linkage disequilibrium with these SNPs. One further SHBG SNP was significantly associated with breast cancer (rs6257, per-allele odds ratio 0.88, 95% CI=0.82-0.95, p=0.002). Conclusion At least three SNPs showed associations with SHBG levels that were highly significant but relatively small in magnitude. rs6257 is a potential breast cancer susceptibility variant, but relationships between the genetic determinants of SHBG levels and breast cancer are complex.

    Pihl, Tina Holberg

    Group specific (Gc) globulin also known as vitamin D-binding protein is part of the extracellular actin-scavenging system that removes actin from the circulation. Actin is an intracellular structural protein, which is released to blood in patients with tissue injury and cell death. Circulating...... can prevent development of shock and thereby increase survival chances. The in vivo toxicity of Gc-globulin infusion is currently being investigated in horses and other species. Gc-globulin has been demonstrated in horse plasma and its structure closely resembles that of human Gc-globulin. Gc...

    2001-07-01

    Corticosteroids are widely used and effective agents for the control of many inflammatory diseases, but corticosteroid osteoporosis is a common problem associated with their long term high dose use. Prevention of corticosteroid osteoporosis is preferable to treatment of established corticosteroid bone loss. Several large double-blind controlled clinical trials in patients with corticosteroid osteoporosis have recently been published that provide new insights into its treatment. Based upon available evidence, the rank order of choice for prophylaxis would be a bisphosphonate followed by a vitamin D metabolite or an oestrogen type medication. Calcium alone appears to be unable to prevent rapid bone loss in patients starting corticosteroids, especially with prednisolone doses at 10 mg a day or greater. If an active vitamin D metabolite is used, calcium supplementation should be avoided unless dietary calcium intake is low. Hormone replacement therapy should be considered if hypogonadism is present. Since vertebral fracture is a common and important complication of high dose corticosteroid therapy, these findings suggest that rapid bone loss and hence fractures, can be prevented by prophylactic treatment. Although the follow-up data is limited, it is likely that such therapy needs to be continued beyond 12 months whilst patients continue significant doses of corticosteroid therapy.

    Full Text Available Low total testosterone (TT and sex hormone-binding globulin (SHBG concentrations have been associated with the metabolic syndrome (MetS in men, but the reported strength of association varies considerably.We aimed to investigate whether associations differ across specific subgroups (according to age and body mass index (BMI and individual MetS components.Two previously published meta-analyses including an updated systematic search in PubMed and EMBASE.Cross-sectional or prospective observational studies with data on TT and/or SHBG concentrations in combination with MetS in men.We conducted an individual participant data meta-analysis of 20 observational studies. Mixed effects models were used to assess cross-sectional and prospective associations of TT, SHBG and free testosterone (FT with MetS and its individual components. Multivariable adjusted odds ratios (ORs and hazard ratios (HRs were calculated and effect modification by age and BMI was studied.Men with low concentrations of TT, SHBG or FT were more likely to have prevalent MetS (ORs per quartile decrease were 1.69 (95% CI 1.60-1.77, 1.73 (95% CI 1.62-1.85 and 1.46 (95% CI 1.36-1.57 for TT, SHBG and FT, respectively and incident MetS (HRs per quartile decrease were 1.25 (95% CI 1.16-1.36, 1.44 (95% 1.30-1.60 and 1.14 (95% 1.01-1.28 for TT, SHBG and FT, respectively. Overall, the magnitude of associations was largest in non-overweight men and varied across individual components: stronger associations were observed with hypertriglyceridemia, abdominal obesity and hyperglycaemia and associations were weakest for hypertension.Associations of testosterone and SHBG with MetS vary according to BMI and individual MetS components. These findings provide further insights into the pathophysiological mechanisms linking low testosterone and SHBG concentrations to cardiometabolic risk.

    The relationship between hyperinsulinemia and decreased sex hormone-binding globulin (SHBG) levels has been observed in obese adults and children. Weight reduction not only increased insulin sensitivity but also elevated serum SHBG levels in obese adults and children. However, the correlation between the changes in insulin resistance indices and serum SHBG concentration during weight reduction program (WRP) is not fully understood, particularly in obese children. This study is to evaluate whether SHBG level is a potential biomarker that can be used to assess insulin resistance in obese children during a short-term WRP. Forty-eight obese Taiwanese children (11.7 ± 2.2 years; 25 boys and 23 girls) participating in 8-week WRP were studied. Anthropometric measurements, lipid profiles, insulin resistance indices, and serum SHBG concentration were recorded at baseline and at the end of the WRP. The results showed body weight (BW), body mass index (BMI), body fat percentage (BF%), body fat weight (BFW), and insulin resistance indices such as fasting insulin, fasting insulin to glucose ratio, homeostasis model assessment (HOMA) of insulin resistance, log (HOMA) all significantly decreased after the 8-week WRP. With respect to lipid profiles, only high-density lipoprotein cholesterol (HDL-C) levels increased in both sexes. At baseline, insulin resistance indices were inversely correlated with SHBG concentrations in girls, but not in boys. The difference in SHBG after WRP was 2.58 nmol/L (95% confidence interval [CI]: -3.51, 8.66) in boys and 0.58 nmol/L (95% CI: -5.23, 6.39) in girls. There was a trend toward increased serum SHBG levels in boys (P = .39) and girls (P = .84) after weight loss, but a significantly negative correlation between the change in SHBG and in each of the insulin resistance indices only in the girls after adjusting age and ΔBFW during WRP.In conclusion, short-term WRP has the potential effects of decreased BW, BMI, BF%, and BFW, as

    Full Text Available Sex hormone-binding globulin (SHBG is a glycoprotein responsible for the transport and biologic availability of sex steroid hormones, primarily testosterone and estradiol. SHBG has been associated with chronic diseases including type 2 diabetes (T2D and with hormone-sensitive cancers such as breast and prostate cancer. We performed a genome-wide association study (GWAS meta-analysis of 21,791 individuals from 10 epidemiologic studies and validated these findings in 7,046 individuals in an additional six studies. We identified twelve genomic regions (SNPs associated with circulating SHBG concentrations. Loci near the identified SNPs included SHBG (rs12150660, 17p13.1, p = 1.8 × 10(-106, PRMT6 (rs17496332, 1p13.3, p = 1.4 × 10(-11, GCKR (rs780093, 2p23.3, p = 2.2 × 10(-16, ZBTB10 (rs440837, 8q21.13, p = 3.4 × 10(-09, JMJD1C (rs7910927, 10q21.3, p = 6.1 × 10(-35, SLCO1B1 (rs4149056, 12p12.1, p = 1.9 × 10(-08, NR2F2 (rs8023580, 15q26.2, p = 8.3 × 10(-12, ZNF652 (rs2411984, 17q21.32, p = 3.5 × 10(-14, TDGF3 (rs1573036, Xq22.3, p = 4.1 × 10(-14, LHCGR (rs10454142, 2p16.3, p = 1.3 × 10(-07, BAIAP2L1 (rs3779195, 7q21.3, p = 2.7 × 10(-08, and UGT2B15 (rs293428, 4q13.2, p = 5.5 × 10(-06. These genes encompass multiple biologic pathways, including hepatic function, lipid metabolism, carbohydrate metabolism and T2D, androgen and estrogen receptor function, epigenetic effects, and the biology of sex steroid hormone-responsive cancers including breast and prostate cancer. We found evidence of sex-differentiated genetic influences on SHBG. In a sex-specific GWAS, the loci 4q13.2-UGT2B15 was significant in men only (men p = 2.5 × 10(-08, women p = 0.66, heterogeneity p = 0.003. Additionally, three loci showed strong sex-differentiated effects: 17p13.1-SHBG and Xq22.3-TDGF3 were stronger in men, whereas 8q21.12-ZBTB10 was stronger in women. Conditional analyses identified additional signals at the SHBG gene that together almost double the proportion

    Full Text Available We investigated 252 non-obese female subjects aged 13-39 years to evaluate if an exaggerated descent of sex hormone binding globulin (SHBG levels during adolescence can play a role in the development of hirsutism. Body hair was assessed according to Ferriman and Gallwey (FG, with a stringent criterion of normality of 4 and controls (FG Se investigaron 252 mujeres con peso normal, de 13 a 39 años de edad, para evaluar si un descenso exagerado en los niveles de la globulina transportadora de hormonas sexuales ("sex hormone binding globulin"; SHBG puede tener un rol en el desarrollo de hirsutismo. Este signo fue evaluado con la escala de Ferriman y Gallwey (FG, empleando un criterio riguroso de normalidad 4 y controles (FG < 4, ciclos menstruales regulares, sin acné. En adolescentes de 15-18 años, los valores de SHBG fueron menores en las "hirsutas", los niveles de FT fueron similares en ambos grupos y el índice de FG correlacionó inversamente con SHBG. En las mujeres de 19-39 años, los niveles de FT fueron mayores en las "hirsutas", los valores de SHBG fueron similares en ambos grupos y FG correlacionó positivamente con FT. Los valores más bajos de SHBG se observaron entre 15 y 18 años, pero la pendiente de disminución a partir de los valores de 13-14 años fue mayor en el grupo de "hirsutas". Los valores de FT se incrementaron progresivamente con la edad, pero el aumento fue mayor en el grupo de "hirsutas". Estos resultados sugieren un rol importante del descenso de SHBG en la adolescencia vs. un incremento más acentuado de los niveles de testosterona en las adultas, como factores que condicionan el desarrollo del hirsutismo en esos dos diferentes periodos de la vida.

  13. Inhaled Corticosteroids

    Full Text Available Inhaled corticosteroids (ICS are the most effective controllers of asthma. They suppress inflammation mainly by switching off multiple activated inflammatory genes through reversing histone acetylation via the recruitment of histone deacetylase 2 (HDAC2. Through suppression of airway inflammation ICS reduce airway hyperresponsiveness and control asthma symptoms. ICS are now first-line therapy for all patients with persistent asthma, controlling asthma symptoms and preventing exacerbations. Inhaled long-acting β2-agonists added to ICS further improve asthma control and are commonly given as combination inhalers, which improve compliance and control asthma at lower doses of corticosteroids. By contrast, ICS provide much less clinical benefit in COPD and the inflammation is resistant to the action of corticosteroids. This appears to be due to a reduction in HDAC2 activity and expression as a result of oxidative stress. ICS are added to bronchodilators in patients with severe COPD to reduce exacerbations. ICS, which are absorbed from the lungs into the systemic circulation, have negligible systemic side effects at the doses most patients require, although the high doses used in COPD has some systemic side effects and increases the risk of developing pneumonia.

    Estrogens are important regulators of physiological functions. Although environmental contaminants (xenoestrogens) which interfere with estrogen signaling are of increasing concern, there is only limited information about their ability to interact with estrogen-binding proteins (SHBG) or receptors (ER). Recombinant ER?? and ?? were obtained after transient transfection of COS-7 cells with channel catfish ER cDNA. Plasma from adult female channel catfish was the source of SHBG. Tritiated estradiol ( 3H-E2) was used in standard radioligand-binding assays to characterize the binding properties of channel catfish SHBG (ccfSHBG) and to estimate the inhibition constants for various estrogenic compounds. Binding of 3H-E2 to ccfSHBG was saturable and of high affinity with a Kd (??SE) of 1.9??0.14nM and a Bmax of 14.3??2.4pmol/mg protein (n=3 assays). Additionally, ccfSHBG displayed binding specificity for androgens and estrogens. Endosulfan, 4-nonylphenol, and 4-octylphenol displaced 3H-E2 binding to ccfSHBG albeit only at very high concentrations, whereas dieldrin and atrazine showed little displacement activity even at the highest concentrations used. The synthetic estrogen ethynylestradiol had higher affinity than E2 for ccfSHBG. This finding differs from results with human and rainbow trout SHBG. The alkylphenolic compounds (4-octylphenol and 4-nonylphenol) displayed some ability to displace 3H-E2 binding from ER?? and ?? at high concentrations, but dieldrin and atrazine had little binding activity for both ER subtypes and endosulfan for ER??. The xenobiotics tested generally showed equivalent or greater affinity for ER?? than ER??, whereas natural estrogens had much greater affinity for ER?? than ER??. These observations suggest that results of studies using fish tissue ER extracts must be interpreted with caution, since both ER subtypes may be present, and that the binding of xenoestrogens to SHBG must be taken into account for proper assessment of endocrine

    Sex hormone binding globulin (SHBG) is a glycoprotein secreted by the liver, which mediates and (or) activates adenylate cyclase system directly through binding with peculiar SHBG receptor in surface of organic cells, thereby regulates cell function. Many studies have explored that, SHBG is related with type 2 diabetes and obesity, and could reflect the extent of insulin resistance in type 2 diabetic patients with obesity. The lower level of SHBG could increase the risk of insulin resistance and type 2 diabetes, and lead to central obesity. Higher serum SHBG reduces diseases such as type 2 diabetes and obesity through regulating fasting blood glucose, but not through improving insulin secretion and androgen mechanism.%性激素结合球蛋白(SHBG)是由肝脏产生的一种糖蛋白,通过与组织细胞表面的特异性受体结合介导和(或)直接激活腺苷酸环化酶系统,从而调节组织细胞功能.研究显示,SHBG与2型糖尿病和肥胖相关,可反映肥胖2型糖尿病患者的胰岛素抵抗程度.低SHBG水平可增加胰岛素抵抗及2型糖尿病的发病风险,可导致腹型肥胖.高血清SHBG通过调整空腹血糖,而不是通过改善胰岛素分泌或雄激素机制,延缓糖尿病及肥胖等疾病的发生.

    2009-01-01

    Full Text Available The case of a 33-year-old man with aplastic anemia who experienced recurrent episodes of hypoxemia and pulmonary infiltrates during infusions of antithymocyte globulin (ATG is described. With the use of high-dose corticosteroids, the patient’s original episodes resolved, and were subsequently prevented before additional administrations of ATG. Rare reports of an association between ATG and acute lung injury are found in the literature, but this is the first report of successful steroid-supported re-exposure. Although the mechanism of ATG-related acute lung injury remains uncertain, it may be parallel to the mechanism of transfusion-related acute lung injury because the pathogenesis of the latter relies, in part, on antileukocyte antibodies. ATG-related toxicity should be included in the differential diagnosis of new, infusion-associated pulmonary infiltrates, and corticosteroids may be a useful therapeutic consideration in the management.

    Full Text Available Seed coat is a specialized maternal tissue that interfaces the embryo and the external environment during embryogenesis, dormancy and germination. In addition, it is the first defensive barrier against penetration by pathogens and herbivores. Here we show that Albizia lebbeck seed coat dramatically compromises the oviposition, eclosion and development of the bruchid Callosobruchus maculatus. Dietary supplementation of bruchid larvae with A. lebbeck seed coat flour causes severe weight loss and reduces survival. By means of protein purification, mass spectrometry and bioinformatic analyses, we show that chitin-binding vicilins are the main source of A. lebbeck tegumental toxicity to C. maculatus. At concentrations as low as 0.1%, A. lebbeck vicilins reduce larval mass from 8.1 ± 1.7 (mass of control larvae to 1.8 ± 0.5 mg, which corresponds to a decrease of 78%. Seed coat toxicity constitutes an efficient defense mechanism, hindering insect predation and preventing embryo damage. We hypothesize that A. lebbeck vicilins are good candidates for the genetic transformation of crop legumes to enhance resistance to bruchid predation.

    In cancer bioassays, inhalation, but not drinking water exposure to ethyl tertiary-butyl ether (ETBE), caused liver tumors in male rats, while tertiary-butyl alcohol (TBA), an ETBE metabolite, caused kidney tumors in male rats following exposure via drinking water. To understand the contribution of ETBE and TBA kinetics under varying exposure scenarios to these tumor responses, a physiologically based pharmacokinetic model was developed based on a previously published model for methyl tertiary-butyl ether, a structurally similar chemical, and verified against the literature and study report data. The model included ETBE and TBA binding to the male rat-specific protein α2u-globulin, which plays a role in the ETBE and TBA kidney response observed in male rats. Metabolism of ETBE and TBA was described as a single, saturable pathway in the liver. The model predicted similar kidney AUC0-∞ for TBA for various exposure scenarios from ETBE and TBA cancer bioassays, supporting a male-rat-specific mode of action for TBA-induced kidney tumors. The model also predicted nonlinear kinetics at ETBE inhalation exposure concentrations above ~2000 ppm, based on blood AUC0-∞ for ETBE and TBA. The shift from linear to nonlinear kinetics at exposure concentrations below the concentration associated with liver tumors in rats (5000 ppm) suggests the mode of action for liver tumors operates under nonlinear kinetics following chronic exposure and is not relevant for assessing human risk.

    The purpose of the present study was to investigate the relationships of change in high density lipoprotein cholesterol (HDL-C) with changes in sex hormone binding globulin (SHBG), physical fitness and spontaneous dietary intake before and after endurance training. Ten pre-menopausal obese women (32 to 49 years) who had never smoked or regularly drunk alcohol participated in this study. Physical training at an intensity of lactate threshold was performed for six months at a frequency of three times per week for 60 minutes using a cycle ergometer. Together with a reduction in body weight (-4.1 kg; P < 0.05) and with increases in maximal oxygen uptake (VO2max = +3.4 ml/kg/min or +0.09 l/min; P < 0.05), the training induced some changes in both plasma lipid and lipoprotein. Although the total cholesterol (total-C), triglyceride, HDL2-C and apoprotein A1 (Apo A1) levels did not change, significant increases in HDL-C and HDL3-C, and significant reductions in Apo B, total-C/HDL-C ratio and fasting insulin concentrations were found after training. SHBG levels tended to increase after endurance training, but the changes were not significant. No alteration was observed in spontaneous dietary intake after training. A significant correlation (r = 0.648) was observed between the change in VO2 max(l/min) and the change in SHBG. In addition, changes in both VO2 max(l/min) and SHBG were significantly associated with changes in HDL-C, HDL2-C and Apo A1. The changes in dietary intake did not correlate with the changes in SHBG, VO2max, HDL-C, HDL2-C and Apo A1.(ABSTRACT TRUNCATED AT 250 WORDS)

    2016-03-01

    Corticosteroids are widely used drugs in the clinical practice, especially by topic application in dermatology. These substances may act as allergens and produce immediate and delayed hypersensitivity reactions. Allergic contact dermatitis is the most frequent presentation of corticosteroid allergy and it should be studied by patch testing in specific units. The corticosteroids included in the Spanish standard battery are good markers but not ideal. Therefore, if those makers are positive, it is useful to apply a specific battery of corticosteroids and the drugs provided by patients. Immediate reactions are relatively rare but potentially severe, and it is important to confirm the sensitization profile and to guide the use of alternative corticosteroids, because they are often necessary in several diseases. In this article we review the main concepts regarding these two types of hypersensitivity reactions in corticosteroid allergy, as well as their approach in the clinical practice.

    Orbital inflammation is common, and may affect all ages and both genders. By combining a thorough history and physical examination, targeted ancillary laboratory testing and imaging, a presumptive diagnosis can often be made. Nearly all orbital inflammatory pathology can be empirically treated with corticosteroids, thus obviating the need for histopathologic diagnosis prior to initiation of therapy. In addition, corticosteroids may be effective in treating concurrent systemic disease. Unless orbital inflammation responds atypically or incompletely, patients can be spared biopsy.

    To investigate the relationship between sex hormone binding globulin (SHBG) and metabolic syndrome in elderly males in Shanghai,all the subjects (≥ 60 years old,male) underwent measurements of weight,height,waist and hip circumferences,and blood pressures,serum levels of fasting plasma glucose,total cholesterol,triglyceride,high density lipoprotein-cholesterol (HDL-C),and low density lipoprotein-cholesterol were determined (Hitachi,7600),while the levels of serum insulin,total testosterone,and SHBG were determined by using chemiluminescence methods.Free testosterone was calculated by using the Vermeulen equation.Metabolic syndrome was defined according to the criteria of the Chinese Diabetes Society (CDS 2004).The SHBG level in the metabolic syndrome group was significantly lower than that in non-metabolic syndrome group [(40.50 ± 26.16) nmol/L vs (47.80± 20.34) nmol/L,P<0.01].With increasing number of metabolic syndrome components,the level of SHBG became lowered progressively.The subjects were divided into four subgroups according to SHBG Quartiles.From Quartile 1 to Quartile 4,body mass index,waist-hip ratio,diastolic blood pressure,fasting plasma glucose,triglyceride,fasting insulin,homeostasis model assessment for insulin resistance(HOMA-IR),free testosterone,free androgen index,and free testosterone percentage became progressively lowered,while age and HDL-C became raised (P<0.05).SHBG was correlated significantly with age,body mass index,waist-hip ratio,diastolic blood pressure,fasting plasma glucose,HDL-C,and triglyceride.Age,HDL-C,and body mass index remained independently associated with SHBG in the multivariate regression analysis.In a logistic regression taking metabolic syndrome as the dependent variable,SHBG and HOMA-IR were included in the final model with statistical significance.Lowered SHBG is a risk factor of metabolic syndrome in elderly males.SHBG may be an independent predictor of metabolic syndrome,but the mechanism of how SHBG is

    Water-restricted rats exhibit a rapid decrease in plasma corticosterone after drinking. The present study examined the effect of restriction-induced drinking on plasma aldosterone and plasma clearance of corticosterone. Rats were water restricted for 6-7 days and then killed before or 15 min after water administration; plasma and adrenal hormones were assayed. Plasma and adrenal corticosterone decreased after drinking without a change in plasma corticosteroid-binding globulin; plasma ACTH decreased or did not change. In contrast, plasma aldosterone did not change or increased after drinking; plasma renin activity was elevated by water restriction and increased further after drinking. In another experiment, rats were adrenalectomized, and corticosterone and aldosterone were replaced with pellets and osmotic minipumps, respectively. Rats were water restricted and killed. There was a small decrease in plasma corticosterone but no change in aldosterone after drinking in adrenalectomized animals. These data suggest that changes in plasma steroids after restriction-induced drinking result from zone-specific responses of the adrenal to known secretagogues, with minimal contribution from increased plasma clearance.

    Corticosteroid hormones are critical for controlling metabolism, hydromineral balance, and the stress response in vertebrates. Although corticosteroid hormones have been well characterized in most vertebrate groups, the identity of the earliest vertebrate corticosteroid hormone has remained elusive. Here we provide evidence that 11-deoxycortisol is the corticosteroid hormone in the lamprey, a member of the agnathans that evolved more than 500 million years ago. We used RIA, HPLC, and mass spectrometry analysis to determine that 11-deoxycortisol is the active corticosteroid present in lamprey plasma. We also characterized an 11-deoxycortisol receptor extracted from sea lamprey gill cytosol. The receptor was highly specific for 11-deoxycortisol and exhibited corticosteroid binding characteristics, including DNA binding. Furthermore, we observed that 11-deoxycortisol was regulated by the hypothalamus-pituitary axis and responded to acute stress. 11-Deoxycortisol implants reduced sex steroid concentrations and upregulated gill Na+, K+-ATPase, an enzyme critical for ion balance. We show here that 11-deoxycortisol functioned as both a glucocorticoid and a mineralocorticoid in the lamprey. Our findings indicate that a complex and highly specific corticosteroid signaling pathway evolved at least 500 million years ago with the arrival of the earliest vertebrate.

    According to the data in the literature, the authors attempted to sum-up present attitudes on the value of corticoids in the treatment of septic shock. If their cardiovascular effects after a period of enthusiasm, are presently rather controversial, their cellular and sub-cellular actions, on the lysosomal membranes, capillary permeability and perhaps the intimate mechanisms of cellular oxygenation seem to be more real. However, the contra-indications which persist in the results of clinical works have resulted in the fact that the exact place of cortico-steroids in the therapeutic arsenal of septic shock still remains to be specified.

    Corticosteroids are extensively used in pediatrics, yet the burden of side effects is significant. Availability of a simple, fast, and reliable biochemical read out of steroidal drug pharmacodynamics could enable a rapid and objective assessment of safety and efficacy of corticosteroids and aid development of corticosteroid replacement drugs. To identify potential corticosteroid responsive biomarkers we performed proteome profiling of serum samples from DMD and IBD patients with and without corticosteroid treatment using SOMAscan aptamer panel testing 1,129 proteins in FGG). These are candidate biomarkers for anti-inflammatory efficacy of corticosteroids. Known safety concerns were validated, including elevated non-fasting insulin (insulin resistance), and elevated angiotensinogen (salt retention). These were extended by new candidates for metabolism disturbances (leptin, afamin), stunting of growth (growth hormone binding protein), and connective tissue remodeling (MMP3). Significant suppression of multiple adrenal steroid hormones was also seen in treated children (reductions of 17-hydroxyprogesterone, corticosterone, 11-deoxycortisol and testosterone). A panel of new pharmacodynamic biomarkers for corticosteroids in children was defined. Future studies will need to bridge specific biomarkers to mechanism of drug action, and specific clinical outcomes. PMID:27530235

    Chronic exposure to methyl isobutyl ketone (MIBK) resulted in an increase in the incidence of renal tubule adenomas and occurrence of renal tubule carcinomas in male, but not female Fischer 344 rats. Since a number of chemicals have been shown to cause male rat renal tumors through the α2u nephropathy-mediated mode of action, the objective of this study is to evaluate the ability of MIBK to induce measures of α2u nephropathy including renal cell proliferation in male and female F344 rats following exposure to the same inhalation concentrations used in the National Toxicology Program (NTP) cancer bioassay (0, 450, 900, or 1800ppm). Rats were exposed 6h/day for 1 or 4 weeks and kidneys excised approximately 18h post exposure to evaluate hyaline droplet accumulation (HDA), α2u staining of hyaline droplets, renal cell proliferation, and to quantitate renal α2u concentration. There was an exposure-related increase in all measures of α2u nephropathy in male, but not female rat kidneys. The hyaline droplets present in male rat kidney stained positively for α2u. The changes in HDA and α2u concentration were comparable to d-limonene, an acknowledged inducer of α2u nephropathy. In a separate in vitro study using a two-compartment vial equilibration model to assess the interaction between MIBK and α2u, the dissociation constant (Kd) was estimated to be 1.27×10(-5)M. This Kd is within the range of other chemicals known to bind to α2u and cause nephropathy. Together, the exposure-related increase in measures of α2u nephropathy, sustained increase in renal cell proliferation along with an indication of reversible binding of MIBK to α2u, support the inclusion of MIBK in the category of chemicals exerting renal effects through a protein droplet α2u nephropathy-mediated mode of action (MoA).

    Low testosterone levels are associated with metabolic and cardiovascular disease risk factor, and have been shown to predict type 2 diabetes mellitus (T2DM), myocardial infarction (MI) and all-cause mortality. It is not known if these associations are causal or not. Recently, it has been shown that the serum testosterone levels are associated with single-nucleotide polymorphisms (SNPs), and we therefore studied the associations between one of these SNPs, rs1799941 on the Sex Hormone-Binding Globulin (SHBG) gene, and MI, T2DM, cancer and death. DNA was prepared from men who participated in the fourth survey of the Tromsø Study in 1994-1995 and who were registered with the endpoints MI, T2DM, cancer or death and a randomly selected control group. For mortality, the observation time was set from 1994, and for the other endpoints from birth. The endpoint data were completed up to 2010-2013. Genetic analyses were successfully performed in 5309 men, of whom 1454 were registered with MI, 638 with T2DM, 1534 with cancer and in 2226 who had died. Men with the minor homozygote genotype had significantly higher levels of total testosterone (14.7%) and SHBG (24.7%) compared with men with the major homozygote genotype, whereas free testosterone levels did not differ significantly between the genotypes. The SNP rs1799941 was not significantly associated with MI, T2DM, cancer or mortality. Thus, our result does not support a causal relationship between total testosterone and SHBG and MI, T2DM, cancer or mortality, suggesting that low testosterone more likely is a marker of poor health.

    Antithymocyte globulin (ATG) has long been used for immune-induction and anti-rejection treatments for solid organ transplantations.To date,few cases of ATG-induced acute respiratory distress syndrome (ARDS) have been published.Here,we present a case of ARDS caused by a single low-dose of ATG in a renal transplant recipient and the subsequent treatments administered.Although the patient suffered from ARDS and delayed graft function,he was successfully treated.We emphasize that the presence of such complications should be considered when unexplained respiratory distress occurs.Early use of corticosteroids,adjustment of immunosuppressive regimens,and conservative fluid management,as well as empiric antimicrobial therapies,may be effective strategies for the treatment of ARDS caused by ATG.

    Acute sinusitis is the inflammation and swelling of the nasal and paranasal mucous membranes and is a common reason for patients to seek primary care consultations. The related impairment of daily functioning and quality of life is attributable to symptoms such as facial pain and nasal congestion. To assess the effects of systemic corticosteroids on clinical response rates and to determine adverse effects and relapse rates of systemic corticosteroids compared to placebo or standard clinical care in children and adults with acute sinusitis. We searched CENTRAL (2014, Issue 1), MEDLINE (1966 to February week 1, 2014) and EMBASE (January 2009 to February 2014). Randomised controlled trials (RCTs) comparing systemic corticosteroids to placebo or standard clinical care for patients with acute sinusitis. Two review authors independently assessed the methodological quality of the trials and extracted data. Five RCTs with a total of 1193 adult participants met our inclusion criteria. We judged methodological quality to be moderate in four trials and high in one trial. Acute sinusitis was defined clinically in all trials. However, the three trials performed in ear, nose and throat (ENT) outpatient clinics also used radiological assessment as part of their inclusion criteria. All participants were assigned to either oral corticosteroids (prednisone 24 mg to 80 mg daily or betamethasone 1 mg daily) or the control treatment (placebo in four trials and non-steroidal anti-inflammatory drugs (NSAIDs) in one trial). In four trials antibiotics were prescribed in addition to oral corticosteroids or control treatment, while one trial investigated the effects of oral corticosteroids as a monotherapy.When combining data from the five trials, participants treated with oral corticosteroids were more likely to have short-term resolution or improvement of symptoms than those receiving the control treatment: at days three to seven (risk ratio (RR) 1.3, 95% confidence interval (CI) 1.1 to 1

  18. Corticosteroid signaling in frog metamorphosis.

    2014-07-01

    Stress in fetal and larval life can impact later health and fitness in humans and wildlife. Long-term effects of early life stress are mediated by altered stress physiology induced during the process of relaying environmental effects on development. Amphibian metamorphosis has been an important model system to study the role of hormones in development in an environmental context. Thyroid hormone (TH) is necessary and sufficient to initiate the dramatic morphological and physiological changes of metamorphosis, but TH alone is insufficient to complete metamorphosis. Other hormones, importantly corticosteroid hormones (CSs), influence the timing and nature of post-embryonic development. Stressors or treatments with CSs delay or accelerate metamorphic change, depending on the developmental stage of treatment. Also, TH and CSs have synergistic, antagonistic, and independent effects on gene regulation. Importantly, the identity of the endogenous corticosteroid hormone or receptor underlying any gene induction or remodeling event has not been determined. Levels of both CSs, corticosterone and aldosterone, peak at metamorphic climax, and the corticosteroid receptors, glucocorticoid and mineralocorticoid receptors, have wide expression distribution among tadpole tissues. Conclusive experiments to identify the endogenous players have been elusive due to difficulties in experimental control of corticosteroid production and signaling. Current data are consistent with the hypothesis that the two CSs and their receptors serve largely overlapping functions in regulating metamorphosis and synergy with TH. Knowledge of the endogenous players is critical to understanding the basic mechanisms and significance of corticosteroid action in regulating post-embryonic development in environmental contexts.

    Family physicians considering corticosteroid injections as part of a comprehensive treatment plan for musculoskeletal diagnoses will find few high-quality studies to assist with evidence-based decision making. Most studies of corticosteroid injections for the treatment of osteoarthritis, tendinopathy, bursitis, or neuropathy include only small numbers of patients and have inconsistent long-term follow-up. Corticosteroid injections for the treatment of adhesive capsulitis result in short-term improvements in pain and range of motion. For subacromial impingement syndrome, corticosteroid injections provide short-term pain relief and improvement in function. In medial and lateral epicondylitis, corticosteroid injections offer only short-term improvement of symptoms and have a high rate of symptom recurrence. Corticosteroid injections for carpal tunnel syndrome may help patients avoid or delay surgery. Trigger finger and de Quervain tenosynovitis may be treated effectively with corticosteroid injections. Patients with hip or knee osteoarthritis may have short-term symptom relief with corticosteroid injections.

    A ~56 kDa protein having hemagglutination activity was purified and characterized from the Murraya paniculata seeds. The gel electrophoresis studies demonstrated that protein is primarily of two different subunits, molecular weight ~ 35 and 21 kDa held together by disulfide-linkages and predominantly by secondary forces. The cloning and sequence analysis revealed that the protein exhibited a substantial sequence identity to seed storage 11S globulin family proteins. The sequence analysis of Murraya paniculata globulin (MPG) demonstrated higher and lower molecular weight polypeptides to be acidic (α) and basic (β) respectively. The sequence analysis further showed that it possesses a characteristic bi-cupin motif and a putative metal binding pocket. CD analysis revealed that the MPG was a β/α protein with a slightly higher content of the former. Conformational changes in protein have been studied by fluorescence spectrometry by using various chemical treatments. The results demonstrated that MPG belongs to 11S globulin family and exhibit's hemagglutination activity, which implicates it to be possessing lectin-like property.

  10. Does corticosterone regulate the onset of breeding in free-living birds?: The CORT-Flexibility Hypothesis and six potential mechanisms for priming corticosteroid function.

    2016-02-01

    For many avian species, the decision to initiate breeding is based on information from a variety of environmental cues, including photoperiod, temperature, food availability, and social interactions. There is evidence that the hormone corticosterone may be involved in delaying the onset of breeding in cases where supplemental cues, such as low food availability and inclement weather, indicate that the environment is not suitable. However, not all studies have found the expected relationships between breeding delays and corticosterone titers. In this review, we present the hypothesis that corticosterone physiology mediates flexibility in breeding initiation (the "CORT-Flexibility Hypothesis"), and propose six possible corticosterone-driven mechanisms in pre-breeding birds that may delay breeding initiation: altering hormone titers, negative feedback regulation, plasma binding globulin concentrations, intracellular receptor concentrations, enzyme activity and interacting hormone systems. Based on the length of the breeding season and species-specific natural history, we also predict variation in corticosterone-regulated pre-breeding flexibility. Although few studies thus far have examined mechanisms beyond plasma hormone titers, the CORT-Flexibility Hypothesis is grounded on a solid foundation of research showing seasonal variation in the physiological stress response and knowledge of physiological mechanisms modulating corticosteroid effects. We propose six possible mechanisms as testable and falsifiable predictions to help clarify the extent of HPA axis regulation of the initiation of breeding.

    Glioblastoma is the most common and most aggressive primary brain tumour. Standard of care consists of surgical resection followed by radiotherapy and concomitant and maintenance temozolomide (temozolomide/radiotherapy→temozolomide). Corticosteroids are commonly used perioperatively to control cerebral oedema and are frequently continued throughout subsequent treatment, notably radiotherapy, for amelioration of side effects. The effects of corticosteroids such as dexamethasone on cell growth in glioma models and on patient survival have remained controversial. We performed a retrospective analysis of glioblastoma patient cohorts to determine the prognostic role of steroid administration. A disease-relevant mouse model of glioblastoma was used to characterize the effects of dexamethasone on tumour cell proliferation and death, and to identify gene signatures associated with these effects. A murine anti-VEGFA antibody was used in parallel as an alternative for oedema control. We applied the dexamethasone-induced gene signature to The Cancer Genome Atlas glioblastoma dataset to explore the association of dexamethasone exposure with outcome. Mouse experiments were used to validate the effects of dexamethasone on survival in vivo Retrospective clinical analyses identified corticosteroid use during radiotherapy as an independent indicator of shorter survival in three independent patient cohorts. A dexamethasone-associated gene expression signature correlated with shorter survival in The Cancer Genome Atlas patient dataset. In glioma-bearing mice, dexamethasone pretreatment decreased tumour cell proliferation without affecting tumour cell viability, but reduced survival when combined with radiotherapy. Conversely, anti-VEGFA antibody decreased proliferation and increased tumour cell death, but did not affect survival when combined with radiotherapy. Clinical and mouse experimental data suggest that corticosteroids may decrease the effectiveness of treatment and shorten

    Corticosteroids are routinely injected into soft tissues, tendon sheaths, bursae, and joints. These anti-inflammatory agents have different potency and solubility, and solubility is inversely correlated with the duration of action. Corticosteroids carry a low risk of complications but commonly cause systemic and local adverse effects. The use of intra-articular corticosteroid injections in the treatment of inflammatory arthritis and osteoarthritis is well established. Evidence also supports the use of injectable corticosteroids in the treatment of inflammatory tenosynovitis and bursitis associated with rheumatic diseases, trigger finger and de Quervain disease, and carpal tunnel syndrome. The role of corticosteroid injections in the management of rotator cuff disease remains unclear. Strong scientific evidence indicates that corticosteroid injections for lateral epicondylosis worsen the long-term outcomes of patients. This review article discusses the considerations related to the use of corticosteroid injections in the management of nonspinal musculoskeletal conditions.

    This study describes in vitro digestion of lupin seed globulins by pancreatin, trypsin and chymotrypsin. Lupin seed globulins turned out to be almost totally susceptible to chymotrypsin digestion. When panceratin or trypsin were used for digestion of lupin seed globulins, γ-conglutin appeared to be resistant to proteolysis. Different fluorescence spectroscopic methods such as fluorescence anisotropy, fluorescence lifetimes and fluorescence quenching measurements were used for detailed characterisation of this phenomenon. A potential reason for γ-conglutin insensitivity to digestion may be related to the fact that lysine, as well as arginine, are positively charged at cell physiological pH. Simultaneously, flavonoids at this pH are partially ionised, which may lead to the occurrence of ionic interactions between these molecules at pH 7.5. The confirmation of this explanation may be the fact that γ-conglutin and vitexin form a static complex, which was observed using fluorescence quenching measurements.

    1998-02-15

    The isolation and characterisation of a cDNA coding for a vicilin-like protein of the fern Matteuccia struthiopteris is described. The corresponding gene is specifically expressed during late stages of spore development. Extensive sequence comparisons suggest that the fern protein can be considered as a molecular missing link between single-domain germin/spherulin-like proteins and two-domain seed storage globulins of gymnosperms and angiosperms. Further, evidence is provided for the existence of a superfamily of structurally related, functionally different proteins which includes storage globulins of the vicilin and legumin families, a membrane-associated sucrose-binding protein of soybean, a Forssman antigen-binding lectin of velvet bean, the precursor of the vacuolar membrane bound proteins MP27/MP32 of pumpkin, the embryogenesis-specific protein Gea8 of carrot, the fern-spore-specific protein described here as well as the functionally diverse family of germins/germin-like proteins and the spherulins of myxomycetes. We propose that seed storage globulins of spermatophytes evolved from desiccation-related single-domain proteins of prokaryotes via a duplicated two-domain ancestor that is best represented by the extant fern spore-specific vicilin-like protein.

    Full Text Available Corticosteroids, one of the most widely prescribed topical drugs, have been used for about six decades till date. However, rampant misuse and abuse down the years has given the drug a bad name. Topical steroid abuse may lead to two major problems which lie at the opposing ends of the psychosomatic spectrum. Topical steroid addiction, a phenomenon that came to be recognized about a decade after the introduction of the molecule is manifested as psychological distress and rebound phenomenon on stoppage of the drug. The rebound phenomenon, which can affect various parts of the body particularly the face and the genitalia has been reported by various names in the literature. TC phobia which lies at the opposite end of the psychiatric spectrum of steroid abuse has been reported particularly among parents of atopic children. Management of both conditions is difficult and frustrating. Psychological counseling and support can be of immense help in both the conditions.

  9. Proposal of abolition of the skin sensitivity test before equine rabies immune globulin application

    Full Text Available An epizootic outbreak of rabies occurred in 1995 in Ribeirão Preto, SP, with 58 cases of animal rabies (54 dogs, 3 cats and 1 bat confirmed by the Pasteur Institute of São Paulo, and one human death. The need to provide care to a large number of people for the application of equine rabies immune globulin (ERIG prevented the execution of the skin sensitivity test (SST and often also the execution of desensitization, procedures routinely used up to that time at the Emergency Unit of the University Hospital of the Faculty of Medicine of Ribeirão Preto, University of São Paulo (EU-UHFMRP-USP, a reference hospital for the application of heterologous sera. In view of our positive experience of several years with the abolition of SST and of the use of premedication before the application of antivenom sera, we used a similar schedule for ERIG application. Of the 1489 victims of animal bites, 1054 (71% received ERIG; no patient was submitted to SST and all received intravenously anti-histamines (anti-H1 + anti-H2 and corticosteroids before the procedure. The patients were kept under observation for 60 to 180 minutes and no adverse reaction was observed. On the basis of these results, since December 1995 ERIG application has been decentralized in Ribeirão Preto and has become the responsibility of the Emergency Unit of the University Hospital and the Central Basic Health Unit, where the same routine is used. Since then, 4216 patients have received ERIG (1818 at the Basic Health Unit and 2398 at the EU-UHFMRP, with no problems. The ideal would be the routine use of human rabies immune globulin (HRIG in public health programs, but this is problematic, because of their high cost. However, while this does not occur, the use of SST is no longer justified at the time of application of ERIG, in view of the clinical evidence of low predictive value and low sensitivity of SST involving the application of heterologous sera. It is very important to point out

  10. Adsorption of antibody and globulin onto glass surfaces.

    1980-10-01

    The amount of globulin adsorbed onto surfaces (97 m2) of porous glass (1 g) in phospate-buffered saline (pH 7.2) was estimated to be 83 mg by frontal analysis. In the adsorption chromatography of rabbit antiserum (the immunoglobulin G class) to horse serum albumin on a porous glass column, immunoglobulin G was not eluted with saline but was eluted with 0.2 M glycine (pH 9) with a recovery of 12%. The yield of immunoglobulin M antibody to sheep red blood cells recovered by elution with saline was 12.3%, and the total yield of immunoglobulin M was 15.8%. Thus, antibody and globulin were well adsorbed onto glass surfaces in physiological saline; immunoglobulin G had a stronger affinity to glass surfaces than did immunglobulin M. These facts should be considered when glass containers are used for purified antiserum.

    Sera and immune globulin (IG) preparations are customarily treated with kaolin before titration of their rubella hemagglutination-inhibiting (HI) antibody in order to rid them of nonspecific inhibitors of hemagglutination. The treatment was shown in this investigation to have no adverse effect on the antibody level of the sera but was found to remove considerable amounts of gamma-globulin from IG preparations. Evidence of this removal was obtained by serological tests, by spectrophotometric determination of protein concentration and by disc electrophoresis. In contrast to kaolin, heparin-manganese chloride (MnCl2) treatment of IG preparations had essentially no effect on the level of antibody globulin by all the criteria used. Heparin-MnCl2-treated IG lots were in these respects similar, if not identical, to their untreated counterparts. Since nonspecific inhibitors associated with the β-lipoprotein fraction of serum are removed by the method employed to fractionate the IG samples, it seems unnecessary to treat the latter in any way for the HI test. No difficulty was encountered in this investigation with several untreated IG lots. Images PMID:4190525

  13. Psychiatric adverse effects of pediatric corticosteroid use.

    2014-06-01

    Corticosteroids, highly effective drugs for myriad disease states, have considerable neuropsychiatric adverse effects that can manifest in cognitive disorders, behavioral changes, and frank psychiatric disease. Recent reviews have summarized these effects in adults, but a comprehensive review on corticosteroid effects in children has not been published since 2005. Here, we systematically review articles published since then that, we find, naturally divide into 3 main areas: (1) chronic effects of acute prenatal and neonatal exposure associated with prematurity and congenital conditions; (2) immediate behavioral effects of acute exposure via oncological protocols; and (3) acute behavioral effects of sporadic use in children and adolescents with other conditions. PsycInfo, MEDLINE, Embase, and Scopus were queried to identify articles reporting psychiatric adverse effects of corticosteroids in pediatric patients. Search terms included corticosteroids, adrenal cortex hormones, steroid psychosis, substance-induced psychoses, glucocorticoids, dexamethasone, hydrocortisone, prednisone, adverse effects, mood disorders, mental disorders, psychosis, psychotic, psychoses, side effect, chemically induced, emotions, affective symptoms, toxicity, behavior, behavioral symptoms, infant, child, adolescent, pediatric, paediatric, neonatal, children, teen, and teenager. Following guidelines for systematic reviews from the Potsdam Consultation on Meta-Analysis, we have found it difficult to draw specific conclusions that are more than general impressions owing to the quality of the available studies. We find a mixed picture with neonates exposed to dexamethasone, with some articles reporting eventual deficits in neuropsychiatric functioning and others reporting no effect. In pediatric patients with acute lymphoblastic leukemia, corticosteroid use appears to correlate with negative psychiatric and behavioral effects. In children treated with corticosteroids for noncancer conditions

  14. Use of intranasal corticosteroids in adenotonsillar hypertrophy.

    This review examined the efficacy of intranasal corticosteroids for improving adenotonsillar hypertrophy. The related literature was searched using PubMed and Proquest Central databases. Adenotonsillar hypertrophy causes mouth breathing, nasal congestion, hyponasal speech, snoring, obstructive sleep apnoea, chronic sinusitis and recurrent otitis media. Adenoidal hypertrophy results in the obstruction of nasal passages and Eustachian tubes, and blocks the clearance of nasal mucus. Adenotonsillar hypertrophy and obstructive sleep apnoea are associated with increased expression of various mediators of inflammatory responses in the tonsils, and respond to anti-inflammatory agents such as corticosteroids. Topical nasal steroids most likely affect the anatomical component by decreasing inspiratory upper airway resistance at the nasal, adenoidal or tonsillar levels. Corticosteroids, by their lympholytic or anti-inflammatory effects, might reduce adenotonsillar hypertrophy. Intranasal corticosteroids reduce cellular proliferation and the production of pro-inflammatory cytokines in a tonsil and adenoid mixed-cell culture system. Intranasal corticosteroids have been used in adenoidal hypertrophy and adenotonsillar hypertrophy patients, decreasing rates of surgery for adenotonsillar hypertrophy.

  15. Effects of Antenatal Corticosteroids in Preterm Delivery

    Directory of Open Access Journals (Sweden)

    Kuo-Gon Wang

    2004-12-01

    Full Text Available Antenatal corticosteroid administration is one of the most effective methods to improve perinatal outcomes. It reduces the incidence of respiratory distress syndrome, intraventricular hemorrhage, periventricular leukomalacia and necrotizing enterocolitis in preterm neonates. Antenatal corticosteroids are also effective in treating maternal hemolysis, elevated liver enzymes and low platelet count syndrome. However, complications in neonates and mothers may occur when antenatal corticosteroids are given, including infection, sepsis and maternal pulmonary edema. The National Institutes of Health Consensus Development Conference recommends treatment regimens of either two 12 mg doses of betamethasone given intramuscularly 24 hours apart or four 6 mg doses of dexamethasone given intramuscularly 12 hours apart between 24 and 34 weeks of gestation in pregnancies at risk for preterm delivery. The benefits are most apparent when the corticosteroids are administered between 24 hours and 7 days before delivery. In principle, antenatal steroid therapy should not be routinely repeated in patients with preterm labor. For preterm premature rupture of membranes at less than 30–32 weeks of gestation, antenatal corticosteroids are also suggested as long as there is no evidence of infection.

    The authors have injected rats with (TH)aldosterone or (TH) corticosterone, plus 100-fold excess of the highly specific glucocorticoid RU 28362, with or without excess unlabeled aldosterone or corticosterone and compared type I receptor occupancy in kidney and hippocampus. Thirty minutes after subcutaneous injection (TH)aldosterone was well retained in renal papilla-inner medulla, renal cortex-outer medulla, and hippocampus; in contrast, (TH)corticosterone was well retained only in hippocampus. Competition studies for (TH)aldosterone binding sites showed corticosterone to be a poor competitor in the kidney compared with hippocampus. Time-course studies, with rats killed 10-180 min after tracer administration, showed very low uptake/retention of (TH)corticosterone by kidney; in hippocampus (TH)corticosterone retention was similar to that of (TH)aldosterone in kidney, and retention of (TH)aldosterone by hippocampus was much more prolonged than of either tracer in any other tissue. Studies in 10-day-old rats, with very low levels of corticosteroid binding globulin (CBG), showed a high degree of aldosterone selectivity in both zones of the kidney, whereas 9TH)aldosterone and (TH)corticosterone were equivalently bound in hippocampus. They interpret these data as evidenced for a mechanism unrelated to extravascular CBG conferring mineralocorticoid specificity on renal type I receptors and propose two models derived from their findings consistent with such differential selectivity.

  17. [Corticosteroids in the treatment of infectious diseases].

    Science.gov (United States)

    Kronig, I; Schibler, M; Rougemont, M; Emonet, S

    2013-04-24

    The addition of a corticosteroid has become a common practice for the treatment of some infectious diseases, such as meningitis, septic shock, moderate to severe Pneumocystis jirovecii pneumonia. The belief that steroids may have a beneficial effect in the early stage of pro-inflammatory infections explains the renewed interest for these treatments. This review of recent literature helps determine the use of steroids in the treatment of infectious diseases as formal guidance, questionable or rather contraindicated. When there is a clear scientific indication for the use of corticosteroids regardless of the current infection, the latter is never a formal contraindication.

    For treatment of severe aplastic anemia, immunosuppressive therapy with horse antithymocyte globulin results in superior response and survival compared with rabbit antithymocyte globulin. This relative benefit may be different in the setting of transplantation as rabbit antithymocyte globulin results in more profound immunosuppression. We analyzed 833 severe aplastic anemia transplants between 2008 and 2013 using HLA-matched siblings (n=546) or unrelated donors (n=287) who received antithymocyte globulin as part of their conditioning regimen and bone marrow graft. There were no differences in hematopoietic recovery by type of antithymocyte globulin. Among recipients of HLA-matched sibling transplants, day 100 incidence of acute (17% versus 6%, p<0.001) and chronic (20% versus 9%, p<0.001) graft-versus-host disease were higher with horse compared to rabbit antithymocyte globulin. There were no differences in 3 year overall survival, 87% and 92%, p=0.76. Among recipients of unrelated donor transplants acute graft-versus-host disease was also higher with horse compared to rabbit antithymocyte globulin (42% versus 23%, p<0.001) but not chronic graft-versus-host disease (38% versus 32%, p=0.35). Survival was lower with horse antithymocyte globulin after unrelated donor transplantation, 75% versus 83%, p=0.02. These data support the use of rabbit antithymocyte globulin for bone marrow transplant conditioning for severe aplastic anemia.

  19. Evolution of ligand specificity in vertebrate corticosteroid receptors

    Deitcher David L

    2011-01-01

    Full Text Available Abstract Background Corticosteroid receptors include mineralocorticoid (MR and glucocorticoid (GR receptors. Teleost fishes have a single MR and duplicate GRs that show variable sensitivities to mineralocorticoids and glucocorticoids. How these receptors compare functionally to tetrapod MR and GR, and the evolutionary significance of maintaining two GRs, remains unclear. Results We used up to seven steroids (including aldosterone, cortisol and 11-deoxycorticosterone [DOC] to compare the ligand specificity of the ligand binding domains of corticosteroid receptors between a mammal (Mus musculus and the midshipman fish (Porichthys notatus, a teleost model for steroid regulation of neural and behavioral plasticity. Variation in mineralocorticoid sensitivity was considered in a broader phylogenetic context by examining the aldosterone sensitivity of MR and GRs from the distantly related daffodil cichlid (Neolamprologus pulcher, another teleost model for neurobehavioral plasticity. Both teleost species had a single MR and duplicate GRs. All MRs were sensitive to DOC, consistent with the hypothesis that DOC was the initial ligand of the ancestral MR. Variation in GR steroid-specificity corresponds to nine identified amino acid residue substitutions rather than phylogenetic relationships based on receptor sequences. Conclusion The mineralocorticoid sensitivity of duplicate GRs in teleosts is highly labile in the context of their evolutionary phylogeny, a property that likely led to neo-functionalization and maintenance of two GRs.

Although anti-vascular endothelial growth factor (VEGF agents are generally used as first-line treatments for patients with center-involving DME, there is an important role for corticosteroids as well. Corticosteroids may be especially useful in pseudophakic patients poorly responsive to anti-VEGF therapies, in patients wishing to reduce the number of required injections, and in pregnant patients. Intravitreal triamcinolone acetonide has been used for many years but is not approved for this indication. An extended-release bioerodable dexamethasone delivery system and an extended-release nonbioerodable fluocinolone acetonide insert have both achieved regulatory approval for the treatment of DME. All intravitreal corticosteroids are associated with risks of cataract progression, elevation of intraocular pressure, and endophthalmitis. There is no current consensus regarding the use of corticosteroids, but they are valuable for selected patients with center-involving DME.

    Background Inhaled corticosteroids are the most commonly used controller therapies for asthma, producing treatment responses in six clinical phenotypes; lung function, bronchodilator response, airway responsiveness, symptoms, need for oral steroids and frequency of emergency department visits and hospitalizations. We hypothesize that treatment response in all of these phenotypes is modulated by a single, quantative corticosteroid responsiveness endophenotype. Objective To develop a composite phenotype that combines multiple clinical phenotypes to measure corticosteroid responsiveness with high accuracy, high stability across populations, and high robustness to missing data. Methods We employed principal component analysis (PCA) to determine a composite corticosteroid responsiveness phenotype that we tested in four replication populations. We evaluated the relative accuracy with which the composite and clinical phenotypes measure the endophenotype using treatment effect area under the receiver operating characteristic curve (AUC). Results In the study population, the composite phenotype measured the endophenotype with an AUC of 0.74, significantly exceeding the AUCs of the six individual clinical phenotypes, which ranged from 0.56 (p-value <.001) to 0.67 (p-value 0.015). In four replication populations with a total of 22 clinical phenotypes available, the composite phenotype AUC ranged from 0.69 to 0.73, significantly exceeded the AUCs of 14 phenotypes, and was not significantly exceeded by any single phenotype. Conclusion The composite phenotype measured the endophenotype with higher accuracy, higher stability across populations, and higher robustness to missing data than any clinical phenotype. This should provide the capability to model corticosteroid pharmacologic response and resistance with increased accuracy and reproducibility. PMID:25951964

  11. Topical corticosteroids: clinical pharmacology and therapeutic use.

    1980-02-01

    The development of topical corticosteroids has enabled many dermatoses to be more effectively treated than previously, but there is also no doubt that misuse of these preparations can lead to troublesome local effects and potentially serious systemic problems. The most effective assay for comparing different compounds has been their vasoconstrictive activity, and this on the whole correlates well with clinical effect. To be effective, corticosteroid must be absorbed and the importance of concentration, occlusion, the type of vehicle, added penetrants such as urea and the anatomical site, on the amount of absorption and therefore on clinical activity has been demonstrated. Ointments have been shown to be more effective than creams but because of the considerable choice of potencies now available most dermatologists tend to prescribe the different formulations according to the wishes of the patient. For the same reason, dilution of the commercially marketed preparations is now not generally recommended. The main therapeutic activity of topical corticosteroids is their nonspecific anti-inflammatory effect, thought to be primarily a result of their action on the chemical mediators of inflammation. They have also been shown to be antimitotic which may well be relevant not only to the treatment of scaling dermatoses but also to their dermal thinning effect resulting from inhibition of fibroblasts. Combinations of corticosteroids with antibacterial and antifungal agents have been shown to be very effective in flexural eruptions and secondarily infected dermatoses. As a general rule, the use of topical corticosteroids in outpatients, unless badly misused, is not associated with any significant risk of adrenal axis suppression, but care must be exercised as to the amount prescribed, especially if large areas of the body are to be treated with highly potent preparations. Certain groups such as young children and patients with liver failure, and certain anatomical sites such

  1. Endogenous synthesis of corticosteroids in the hippocampus.

    Shimpei Higo

    Full Text Available BACKGROUND: Brain synthesis of steroids including sex-steroids is attracting much attention. The endogenous synthesis of corticosteroids in the hippocampus, however, has been doubted because of the inability to detect deoxycorticosterone (DOC synthase, cytochrome P450(c21. METHODOLOGY/PRINCIPAL FINDINGS: The expression of P450(c21 was demonstrated using mRNA analysis and immmunogold electron microscopic analysis in the adult male rat hippocampus. DOC production from progesterone (PROG was demonstrated by metabolism analysis of (3H-steroids. All the enzymes required for corticosteroid synthesis including P450(c21, P450(2D4, P450(11β1 and 3β-hydroxysteroid dehydrogenase (3β-HSD were localized in the hippocampal principal neurons as shown via in situ hybridization and immunoelectron microscopic analysis. Accurate corticosteroid concentrations in rat hippocampus were determined by liquid chromatography-tandem mass spectrometry. In adrenalectomized rats, net hippocampus-synthesized corticosterone (CORT and DOC were determined to 6.9 and 5.8 nM, respectively. Enhanced spinogenesis was observed in the hippocampus following application of low nanomolar (10 nM doses of CORT for 1 h. CONCLUSIONS/SIGNIFICANCE: These results imply the complete pathway of corticosteroid synthesis of 'pregnenolone →PROG→DOC→CORT' in the hippocampal neurons. Both P450(c21 and P450(2D4 can catalyze conversion of PROG to DOC. The low nanomolar level of CORT synthesized in hippocampal neurons may play a role in modulation of synaptic plasticity, in contrast to the stress effects by micromolar CORT from adrenal glands.

    2017-06-01

    Full Text Available Diabetic macular edema is the most common cause of visual impairment in patients with diabetes mellitus. The pathogenesis of macular edema is complex and multifactorial. For many years, laser photocoagulation has been considered the standard therapy for the treatment of diabetic macular edema; however, few patients achieve significant improvements in visual acuity. Today the intravitreal administration of anti-inflammatory or anti-angiogenic agents together with the use of laser photocoagulation represents the standard of care for the treatment of this complication. The intravitreal route of administration minimizes the systemic side effects of corticosteroids. Steroid-related ocular side effects are elevated intraocular pressure and cataract, while injection-related complications include endophthalmitis, vitreous hemorrhage, and retinal detachment. In order to reduce the risks and complications, intravitreal implants have been developed recently to provide sustained release of corticosteroids and reduce repeated injections for the management of diabetic macular edema. In this review, the efficacy, safety, and therapeutic potential of intravitreal corticosteroids in diabetic macular edema are discussed with a review of recent literature.

  4. STUDIES ON THE BLOOD PROTEINS : I. THE SERUM GLOBULINS IN BACTERIAL INFECTION AND IMMUNITY.

    Hurwitz, S H; Meyer, K F

    1916-11-01

    The progress of an infection is usually associated with marked changes in the serum proteins. There may be an increase in the percentage of the total protein during some stage of the infection, and there is usually a change in the albumin-globulin ratio with an increase in the total globulins. This rise may antedate the development of any resistance by a considerable period of time. The non-protein constituents of the blood show fluctuations with a tendency to rise as the infection progresses. The process of immunization is in almost all instances associated with a definite increase in the globulins of the blood, and in some cases with a complete inversion of the normal albumin-globulin ratio. This may be produced both by living and dead organisms and by bacterial endotoxins. Massive doses usually result in an upset which shows no tendency to right itself during the period of observation. A rise in the globulins has been shown to occur long before the animal develops immune bodies in any appreciable concentration; and where the globulin curve and antibody curve appear to parallel one another, it can be shown by a careful analysis of both curves that there is a definite lack of correspondence at various periods of the experiment. Animals possessing a basic immunity show a more rapid rise in the globulin curve following inoculation. There is no parallelism between the leukocytic reaction and the globulin reaction. During periods of leukopenia the globulins may be as high as during the period of a leukocytosis. Bacterial endotoxins produce as striking an increase in the serum globulins as do living and killed bacteria. This would seem to indicate that a bacterial invasion of the organism is not absolutely essential for the globulin changes, and that the toxogenic factor in infection and immunity must play a part in the production of the changes noted. Inflammatory irritants injected intraperitoneally also result in a globulin increase. In this case the changes

    Determine the relative mortality in apparently healthy adults with various levels of serum globulin. By use of the Social Security Death Master File, mortality in 2010 was determined for 7.7 million life insurance applicants age 20 to 89 providing blood samples with valid globulin results between 1992 and 2006. Relative mortality by Cox regression for bands of globulin values was determined by age-sex group, with age split into 20 to 59 and 60 to 89, with each grouping also including age as a covariate. Further analysis was conducted by excluding applicants with elevations of other test values associated with increased globulin levels and mortality risk. After accounting for the mortality impact of frequently associated laboratory test abnormalities including BMI, alkaline phosphatase and albumin, relative mortality was found to increase gradually for globulin values > 3.2 g/dL. Values > 4.0 were associated with a mortality risk that was approximately doubled. There is also a small increased risk for globulin values < 1.9 g/dL. The highest 20% of globulin levels were associated with steadily increasing mortality in life insurance applicants. In many cases, other laboratory findings were not informative of the risk.

    1995-04-01

    A gene encoding a globulin from a major taro (Colocasia esculenta L. Schott) corm protein family, tarin (G1, ca. 28 kDa) was isolated from a lambda Charon 35 library, using a cDNA derived from a highly abundant corm-specific mRNA, as probe. The gene, named tar1, and the corresponding cDNA were characterized and compared. No introns were found. The major transcription start site was determined by primer extension analysis. The gene has an open reading frame (ORF) of 765 bp, and the deduced amino acid sequence indicated a precursor polypeptide of 255 residues that is post-translationally processed into two subunits of about 12.5 kDa each. The deduced protein is 45% homologous to curculin, a sweet-tasting protein found in the fruit pulp of Curculigo latifolia and 40% homologous to a mannose-binding lectin from Galanthus nivalis. Significant similarity was also found at the nucleic acid sequence level with genes encoding lectins from plant species of the Amaryllidaceae and Lilliaceae families.

    Background Herpes simplex virus (HSV) infection carries one of the poorest outcomes of neonatal liver failure (NLF). Neonates with disseminated HSV infection can develop hemophagocytic lymphohistiocytosis (HLH), and occasionally need orthotopic liver transplantation. Early interventions may be critical for the cure of NLF. Case Report We describe herewith a 6-day-old neonate with fulminant hepatic failure due to disseminated HSV-1 infection, who successfully responded to high-dose corticosteroid therapy 72 hours after the onset of disease. Preceding acyclovir, gamma globulin, and exchange blood transfusion therapies failed to control the disease. Methylprednisolone pulse therapy led to a drastic improvement of liver function and cytokine storms, and prevented the disease progression to HLH. Sustained levels of plasma and cerebrospinal fluid HSV DNA declined after prolonged acyclovir therapy. Bilateral lesions of the periventricular white matter areas, assessed by magnetic resonance imaging, disappeared at 3 months of age. The infant showed normal growth and development at 4 years of age. Conclusion Early anti-hypercytokinemia therapy using corticosteroid, and prolonged antiviral therapy might only provide the transplantation-free cure of NLF with HSV dissemination.

    2015-01-01

    Corticosteroids are widely used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). In contrast to their use in mild-to-moderate asthma, they are less efficacious in improving lung function and controlling the underlying inflammation in COPD. In most clinical trials, corticosteroids have shown little benefit in COPD, but have shown a greater clinical effect in combination with long-acting bronchodilators. Impaired corticosteroid activation of the glucocorticoid receptor (GR) has been reported in corticosteroid-insensitive individuals. Reversal of corticosteroid-insensitivity by enhancing GR nuclear translocation is a potential therapeutic target. Preclinical studies suggest members of the nuclear receptor superfamily may facilitate glucocorticoid receptor nuclear translocation. Unravelling the mechanisms that govern GR nuclear translocation may identify novel therapeutic targets for reversing corticosteroid-insensitivity.

    This work studies specific interactions and compatibility between a legumin and a linear carboxylated polysaccharide using gel permeation chromatography, sedimentation analysis, SDS gel electrophoresis, viscometry and phase analysis measurements. It uses the system water/11 S globulin/CMC as a model. Carboxymethylcellulose (CMC) molecules are able to cause a partial dissociation of the protein, subsequent formation of soluble interbiopolymeric complexes and partial aggregation of the free non combined protein at room temperature and pH 6.0-6.5. The maximal binding of biopolymers is observed at their equimolar ratio. The decrease in temperature of the mixture from 293 to 277 K leads to formation of the complex coacervate. The increase in pH from 6.0 to 7.6 results in suppression of complex formation and manifestation of the phenomenon of thermodynamic incompatibility if the total concentration of biopolymers in the system exceeds the critical concentration of segregative phase separation.

    1978-09-01

    The widespread use of corticosteroids in clinical practice emphasises the need for a thorough understanding of their metabolic effects. In general, the actions of corticosteroids on carbohydrate, protein, and lipid metabolism result in increased hepatic capacity for gluconeogenesis and enhanced catabolic actions upon muscle, skin, lymphoid, adipose and connective tissues. Because of the morbidity associated with steroid therapy, the clinician must carefully consider in each case the gains that can reasonably be expected from corticosteroid therapy versus the inevitable undesirable side effects of prolonged therapy. Thus, it is important to remember that the enhanced anti-inflammatory activity of the various synthetic analogues of cortisol is not dissociated from the expected catabolic actions of glucocorticoid hormones. Replacement therapy with physiological doses of cortisol in primary or secondary adrenal insufficiency is intended to simulate the normal daily secretion of cortisol. Short term, high dose suppressive glucocorticoid therapy is indicated in the treatment of medical emergencies such as necrotising vasculitis, status asthmaticus and anaphylactic shock. With improvement of the underlying disorder, the steroid dosage can be rapidly tapered and then discontinued over a 2 to 3 day period. Long term, high dose suppressive therapy is often commonly used to treat certain diseases (see sections 4.7.2 and 4.7.3). In this setting, suppression of the hypothalamic-pituitary-adrenal axis may persist for as long as 9 to 12 months following steroid withdrawal if steroid doses are administered in the supraphysiological range for longer than 2 weeks. In general, higher doses, longer duration of usage, and frequent daily administration are all correlated with the severity of pituitary ACTH suppression. When steroid therapy is to be withdrawn, gradual tapering of the dosage is necessary; the steroid dosage should also be given as a single morning dose if possible. Rapid

    Guidelines on the appropriate use of perioperative steroids in patients with inflammatory bowel disease (IBD) are lacking. As a result, corticosteroid supplementation during and after colorectal surgery procedures has been shown to be highly variable. A clearer understanding of the indications for perioperative corticosteroid administration relative to preoperative corticosteroid dosing and duration of therapy is essential. In this review, we outline the basic tenets of the hypothalamic-pituitary-adrenal (HPA) axis and its normal response to stress, describe how corticosteroid use is thought to affect this system, and provide an overview of the currently available data on perioperative corticosteroid supplementation including the limited evidence pertaining to patients with inflammatory bowel disease. Based on currently existing data, we define "adrenal suppression," and propose a patient-based approach to perioperative corticosteroid management in the inflammatory bowel disease population based on an individual's historical use of corticosteroids, the type of surgery they are undergoing, and HPA axis testing when applicable. Patients without adrenal suppression (corticosteroid supplementation in the perioperative period; patients with adrenal suppression (>20 mg prednisone per day) should be treated with additional perioperative corticosteroid coverage above their baseline home regimen; and patients with unclear HPA axis function (>5 and <20 mg prednisone per day) should undergo preoperative HPA axis testing to determine the best management practices. The proposed management algorithm attempts to balance the risks of adrenal insufficiency and immunosuppression.

    Full Text Available Lablab bean (Dolichos lablab seeds is a potential source of protein globulin.The bean’s protein content is 20.86 %, and the amount of globulin was more than 60% from the total protein, having major fractions of 7S and 11S. The objectives of this research were to explore the 7S globulin fractions, to study interaction between 7S globulin fractions with xanthan gum, and to observe the functional properties of the product of the interaction. The research was conducted in 2 steps. The first step was to fractionate the 7S fractions from globulin. The second steps was to interact 7S globulin fraction with xanthan gum. The yield of these interaction were examined for its physicochemical and functional properties. The results showed that the 7S globulin fractions could be interacted by xanthan gum at pH 7. The interacted product of globulin 7S fraction 10 % with xanthan gum 0,75 % had good functional properties than globulin 7S fraction, such as oil holding capacity, foaming capacity, and emulsion activity. Water holding capacity could not be detected because the yield became soluble. However,the foaming and emulsifying stability were still lower than those of soybean protein isolates. The research concluded that xanthan gum could be used to improve the physicochemical and functional properties of globulin 7S fraction.

    Antithymocyte globulin (ATG) is used in the prevention of graft-versus-host disease during allogeneic hematopoietic stem cell transplantation. It is generally accepted that ATG mediates its immunosuppressive effect primarily via depletion of T cells. Here, we analyzed the impact of ATG-Fresenius (now Grafalon(®)) on human monocyte-derived dendritic cells (DC). ATG induced a semi-mature phenotype in DC with significantly reduced expression of CD14, increased expression of HLA-DR, and intermediate expression of CD54, CD80, CD83, and CD86. ATG-DC showed an increase in IL-10 secretion but no IL-12 production. In line with this tolerogenic phenotype, ATG caused a significant induction of indoleamine 2,3-dioxygenase expression and a concomitant increase in levels of tryptophan metabolites in the supernatants of DC. Further, ATG-DC did not induce the proliferation of allogeneic T cells in a mixed lymphocyte reaction but actively suppressed the T cell proliferation induced by mature DC. These data suggest that besides its well-known effect on T cells, ATG modulates the phenotype of DC in a tolerogenic way, which might constitute an essential part of its immunosuppressive action in vivo.

    A series of 37 patients, all with a presumptive diagnosis of plantar fascia rupture, is presented. All had had prior heel pain diagnosed as plantar fasciitis, and all had been treated with corticosteroid injection into the calcaneal origin of the fascia. One third described a sudden tearing episode in the heel, while the rest had a gradual change in symptoms. Most of the patients had relief of the original heel pain, which had been replaced by a variety of new foot problems, including dorsal and lateral midfoot pain, swelling, foot weakness, metatarsal pain, and metatarsal fracture. In all 37 patients, there was a palpable diminution in the tension of the plantar fascia on the involved side, and footprints often showed a flattening of the involved arch. Magnetic resonance imaging done on one patient showed attenuation of the plantar fascia. From these observations and data, the author concluded that plantar fascia rupture had occurred. Treatment following rupture included supportive shoes, orthoses, and time. The majority had resolution of their new symptoms, but this often took 6 to 12 months to occur. In the remainder, there were persisting symptoms. Corticosteroid injections, although helpful in the treatment of plantar fasciitis, appear to predispose to plantar fascia rupture.

    In spite of considerable experience of practical use of serum globulin preparations, their effect on automicroflora wasn't studied. The favorable effect of therapeutic injection of homologous serum globulin preparations on automicroflora of small and large intestine of mices was established for the model of acute radiation sickness caused by /sup 60/Co irradiation with 700 R dose. The effect of injecting two types of globulin preparations was studied: ones prepared of blood of intact and hemostimulated mices (to increase the content of normal antitissue antibodies in the serum). Besides the general globulin fraction isolated by ammonium sulfate precipitation a study was made on the effect of purified IgG and IgM preparations. Threefold subcutaneous or intraperitoneal globulin in ection of 1 ..mu..g dose in a mice prevented after 2, 24, 48 h after irradiation the development of bacteriosis, typical for radiation injury - decreased accumulation of putrefactive bacteria and reduced the suppression of lactobacilli content. Globulin preparations and fractions of hemostimulated mice serum, enriched by normal antitissue antibodies are the most effective ones.

    The delayed hypersensitivity development against topical corticosteroids which are used in allergic contact dermatitis (ACD) treatment is an important clinical problem. In our study, 41 ACD patients who did not show any response to topical corticosteroid treatment were patch tested with corticosteroid series and the commercial preparations of corticosteroids and their vehicles. In corticosteroid series, there were budesonide, bethametasone-17-valerate, triamcinolone acetonide, tixocortol pivalate, alclomethasone-17-21-dipropionate, clobetasole-17-propionate, dexamethasone-21-phosphate disodium and hydrocortisone-17-butyrate. We detected positive reaction to corticosteroids in 9 of our cases (22%) (5 single and 4 multiple). The sensitivity was mostly produced by tixocortol pivalate (6 patients). This was followed by triamcinolone acetonide (2 patients) budesonide (2 patients), alclomethasone dipropionate (2 patients), dexamethasone 21 phosphate disodium (2 patients) and betamethasone-17-valerate (1 patient). As a result, it should not be forgotten that the corticosteroids used to treat ACD patients may cause ACD themselves. In ACD patients who did not respond to corticosteroid treatment, routinely applying patch test with corticosteroids should be helpful in directing the treatment.

    Full Text Available The potential benefits of corticosteroids for septic shock may depend on initial mortality risk.We determined associations between corticosteroids and outcomes in children with septic shock who were stratified by initial mortality risk.We conducted a retrospective analysis of an ongoing, multi-center pediatric septic shock clinical and biological database. Using a validated biomarker-based stratification tool (PERSEVERE, 496 subjects were stratified into three initial mortality risk strata (low, intermediate, and high. Subjects receiving corticosteroids during the initial 7 days of admission (n = 252 were compared to subjects who did not receive corticosteroids (n = 244. Logistic regression was used to model the effects of corticosteroids on 28-day mortality and complicated course, defined as death within 28 days or persistence of two or more organ failures at 7 days.Subjects who received corticosteroids had greater organ failure burden, higher illness severity, higher mortality, and a greater requirement for vasoactive medications, compared to subjects who did not receive corticosteroids. PERSEVERE-based mortality risk did not differ between the two groups. For the entire cohort, corticosteroids were associated with increased risk of mortality (OR 2.3, 95% CI 1.3-4.0, p = 0.004 and a complicated course (OR 1.7, 95% CI 1.1-2.5, p = 0.012. Within each PERSEVERE-based stratum, corticosteroid administration was not associated with improved outcomes. Similarly, corticosteroid administration was not associated with improved outcomes among patients with no comorbidities, nor in groups of patients stratified by PRISM.Risk stratified analysis failed to demonstrate any benefit from corticosteroids in this pediatric septic shock cohort.

    Corticosteroid therapy as adjunctive treatment in community-acquired pneumonia (CAP) is a promising but controversial subject. The potentially beneficial effect of corticosteroids is based on the ability of steroids to dampen an excessive inflammatory response that often occurs in patients with CAP. This excessive inflammatory response can cause damage to the lungs and other organs, and is associated with poor outcome.

    Full Text Available Infections of central nervous system are still a major problem. Despite the introduction of newer antimicrobial agents, mortality and long-term sequelace associated with these infections is unacceptably high. Based on the evidence that proinflammtory cytokines have a role in pathophysiology of bacterial and tuberculous meningitis, corticosteroids with a potent anti-inflammatory and immunomodulating effect have been tested and found to be of use in experimental and clinical studies, Review of the available literature suggests steroid administration just prior to antimicrobial therapy is effective in decreasing audiologic and neurologic sequelae in childern with H. influenzae nenigitis. Steroid use for bacterial meningitis in adults is found to be beneficial in case of S. pneumoniae. The value of adjunctive steroid therapy for other bacterial causes of meningitis remains unproven. Corticocorticoids are found to be of no benefit in viral meningitis, Role of steroids in HIV positive patients needs to be studied.

    Full Text Available Introduction Lack of exact clinical studies on effects of corticosteroids in therapy and prevention of herpes zoster-related pain, elicited many controversies in the past. The aim of our study was to estimate effects of prednisone on frequency, intensity and duration of postherpetic neuralgia. Material and methods 68 immunocompetent herpes zoster patients, 8-90 years of age (37 females and 31 males, mean age 55,7 years were enrolled for study; 30 patients were treated with acyclovir (5x800 mg daily for a 7-day period and prednisone (initial daily dose 60 mg, tapering over 14 days, and the control group of 38 patients with acyclovir only. Patients were clinically followed up for 3 months after complete resolution of skin lesions. Chi-square test was used in statistical data analysis. Results The difference regarding incidence of postherpetic neuralgia in acyclovir/prednisone group and acyclovir group (although slightly less in the former one was not significant. Duration of postherpetic neuralgia over 3 months was similar in both groups. Mild postherpetic pain was more common in the acyclovir/prednisone group (44.4% than in the acyclovir group (28.6%; however, statistical validation requires more patients to be studied. Discussion Results of our study didn’t confirm efficiency of prednisone regarding occurrence and characteristics of postherpetic neuralgia. Failure of prednisone therapy may be partly contributed to advanced age of patients and delayed onset of therapy. Conclusion Use of corticosteroids in zoster patients gives neither reliable protection from appearance of postherpetic neuralgia, nor shortens its duration. Further investigations are necessary to estimate their effects on postherpetic pain.

    Full Text Available OBJETIVO: Realizar uma revisão bibliográfica sobre o uso antenatal do corticosteroide na prevenção da hemorragia peri-intraventricular. FONTES DE DADOS: Levantamento bibliográfico por meio do Pubmed e SciELO abrangendo os últimos 20 anos. Foram utilizadas as palavras chaves no idioma inglês: "cerebral hemorrhage", "steroids" e "newborn, infant". SÍNTESES DE DADOS: A hemorragia peri-intraventricular é uma importante patologia nos prematuros, sobretudo nos menores de 34 semanas, devido a suas graves sequelas neurológicas. Uma vez ocorrido o sangramento, não há tratamento específico. Desta forma, a prevenção torna-se o maior objetivo das pesquisas. O resultado da meta-análise de estudos randomizados demonstrou que o corticosteroide antenatal reduz a mortalidade e a incidência da doença de membrana hialina e da hemorragia peri-intraventricular. O efeito protetor na redução do risco da hemorragia peri-intraventricular não está completamente esclarecido. Além de acelerar a maturidade pulmonar, o corticosteroide antenatal estimula a maturação da microvasculatura da matriz germinativa, promove o espessamento da membrana basal, acelera a formação proteica nas junções firmes e estabiliza o fluxo sanguíneo cerebral. Também melhora as condições de nascimento dos fetos pré-termo. CONCLUSÕES: O uso antenatal do corticosteroide associado à implementação de melhores práticas de atendimento ao prematuro tem sido responsável pela evidente redução dos índices dessa doença. Apesar de comprovada eficácia e segurança, não é amplamente utilizado. Medidas devem ser tomadas para estimular seu uso como prática rotineira no atendimento de gestantes com risco de parto prematuro.OBJECTIVE: To conduct a literature review on the use of antenatal corticosteroids for the prevention of peri-intraventricular hemorrhage.

    The use of systemic and inhaled corticosteroids for COPD has increased appreciably over the past 20 years. Clearer indications for corticosteroid therapy in COPD are beginning to emerge as the results from large clinical trials become available. Systemic corticosteroids are only modestly effective for acute COPD exacerbations, increase the risk for hyperglycemia, and should be given for no more than 2 weeks. The efficacy of long-term systemic corticosteroid therapy has not been adequately evaluated in this patient population. If longer term use of systemic steroids in COPD should be found to be useful, this conclusion would have to be weighed against the risk for serious adverse effects. High doses of inhaled corticosteroids cause a small sustained increase of the FEV1 in patients with mild and moderately severe COPD, but they do not slow the rate of FEV1 decline. Based on analyses of secondary outcome, inhaled corticosteroids may improve the respiratory symptoms and decrease the number and severity of COPD exacerbations in patients with more advanced disease. Low doses of inhaled corticosteroids appear to be safe, but there is growing awareness that higher doses may not be so benign.

    Corticosteroids have been used in preterm infants with immature lungs to decrease their need for supplemental oxygen and mechanical ventilation. Whether the benefits of the treatment outweigh possible adverse effects remains controversial. The main objective of the study was to evaluate the effects of intravenous and inhalation corticosteroids on preterm infants' need for supplemental oxygen and mechanical ventilation and potential adverse effects. This was a retrospective cohort study on preterm infants at the Neonatal Intensive Care Unit of Children's Hospital Iceland, born between 2000-2014 and treated with intravenous (n=28) or inhalation (n=30) corticosteroids for immature lung disease. For each infant receiving steriods one infant who did not receive steriods was selected as control, matched on gestational age. There was a significant decrease in the need for supplemental oxygen following intravenous and inhalation corticosteroids administration, and a significant decrease in the need for mechanical ventilation following intravenous corticosteroids administration, but not in controls. Infants receiving intravenous corticosteroids gained significantly less weight than controls during treatment, but no significant difference in weight between groups was found at 35 weeks postmenstrual age, or in other possible adverse effects such as the prevalence of cerebral palsy. Intravenous and inhalation corticosteroids decrease the need for supplemental oxygen in preterm infants with immature lung disease and intravenous steriods facilitate earlier weaning from mechanical ventilation, without significant adverse effects. Therefore, it seems justifiable in selected cases to use corticosteroids in treatment of preterm infants with severe immature lung disease.

    Pneumocystis jirovecii pneumonia (PCP) is increasingly reported in patients without HIV. Corticosteroids are a major risk factor, with up to 90% of patients receiving corticosteroid treatment prior to the development of PCP. In view of this, many specialties now prescribe PCP prophylaxis to patients receiving prolonged or high-dose glucocorticoid regimens. Neurologists frequently prescribe corticosteroids but may not be as aware of the risk for PCP. Here, we review the evidence for routine PCP prophylaxis among regular glucocorticoid users and ask what guidance there is on the subject for neurologists.

Twenty rabbits weighing 1000 – 1800 g were divided into 2 groups. Each group consisted of ten animals. One served as control and other group served as experimental group. Results show that animals after 07, 15 and 30 days dosing of Aloe vera showed highly significant decrease in total protein and globulin and highly significant decrease in Albumin after 15 and 30 days of dosing of Aloe vera in comparison to control animals group. It is concluded that the long-term use of Aloe vera may cause hypoglobinemia and hypoalbuminemia at 30 days of dosing and it could be due to the liver diseases, evidence of hepatotoxicity induced Aloe vera also reported in previous studies.

    Full Text Available Intranasal corticosteroids are recommended as one of the first-line therapies for the treatment of allergic rhinitis (AR, especially when associated with nasal congestion and recurrent symptoms. Fluticasone furoate is a novel enhanced-affinity glucocorticoid for the treatment of AR approved by the Food and Drug Administration in 2007 and recently introduced in India. Fluticasone furoate nasal spray is indicated for the treatment of the symptoms of seasonal and perennial AR in patients aged two years and older. This review summarizes the clinical data on fluticasone furoate nasal spray and discusses its role in the management of AR. Important attributes of fluticasone furoate include low systemic bioavailability (<0.5%, 24-h symptom relief with once-daily dosing, comprehensive coverage of both nasal and ocular symptoms, safety and tolerability with daily use, and availability in a side-actuated device that makes medication delivery simple and consistent. With these properties, fluticasone furoate nasal spray has the potential to enhance patient satisfaction and compliance, thus making it a good choice amongst available intranasal steroids.

  6. Early interventions in asthma with inhaled corticosteroids.

    We have earlier shown epithelial damage in the airway mucosa in patients with asthma. Later other structural changes have been recognized in asthma, such as deposition of collagen and tenascin in the subepithelial basement membrane and changes in the laminin subchain composition. These processes are modified by an inflammatory process in the airways. Both the United States National Institutes of Health and the British Thoracic Society guidelines on the management of asthma emphasize the need for early use of anti-inflammatory drugs. Many clinical studies that used airway biopsy specimens have shown a decrease in airway inflammatory cell numbers after inhaled corticosteroid therapy. However, there is very little information on the effects of asthma medication on the structural components of the airways. Both the synthesis and degradation of many extracellular matrix components may be affected by the disease process and the drugs resulting in altered remodeling and gene expression in the airways. Because there are only a few studies that try to identify early changes in asthma, it is not known whether the anti-inflammatory treatment of asthma proposed by the guidelines is started early enough.

The aim of this study was to analyse and evaluate the hypoglycaemic activity of storage proteins of five species of Cucurbitaceae, which include Telfairia occidentalis, Citrullus lanatus, Lagenaria siceraria, Cucumeropsis mannii and Cucurbita moschata. Methods The different families of storage proteins were extracted following differential solubility, and their contents were estimated using the Bradford method. The analysis of these proteins was done by electrophoresis in non-denaturing and denaturing conditions. The evaluation of hypoglycaemic properties of various globulins extracted was performed on male Wistar rats by the oral glucose tolerance test. Results The results showed that among the proteins extracted, globulins constitute the most abundant class of storage proteins in all five species selected. Citrullus lanatus and Cucurbita moschata presented the highest levels of globulin (275.34 and 295.11 mg/g dry matter, respectively). The results of electrophoresis showed that all species possess acidic and neutrals albumins and globulins, with molecular weight of protein subunits ranging from 6.36-44.11 kDa for albumins, 6.5-173.86 kDa for globulins and 6.5-49.66 kDa for glutelins. The 6.36 kDa of albumin subunit protein and the 6.5 kDa of globulin subunit protein were present in all the species. The oral glucose tolerance test showed that the globulins of the seeds of all species except Cucumeropsis mannii caused significant drop in blood sugar (88 – 137.80%, compared to the controls, p<0.05). Conclusions These findings showed that the selected Cucurbitaceae

    Full Text Available Background. Proteomic analysis is emerging as a highly useful tool in food research, including studies of food allergies. Two-dimensional gel electrophoresis involving isoelectric focusing and sodium dodecyl sulfate polyacrylamide gel electrophoresis is the most effective method of separating hundreds or even thousands of proteins. In this study, albumin and globulin tractions of pea seeds cv. Ramrod were subjected to proteomic analysis. Selected potentially alergenic proteins were identified based on their molecular weights and isoelectric points. Material and methods. Pea seeds (Pisum sativum L. cv. Ramrod harvested over a period of two years (Plant Breeding Station in Piaski-Szelejewo were used in the experiment. The isolated albumins, globulins and legumin and vicilin fractions of globulins were separated by two-dimensional gel electrophoresis. Proteomic images were analysed in the ImageMaster 2D Platinum program with the use of algorithms from the Melanie application. The relative content, isoelectric points and molecular weights were computed for all identified proteins. Electrophoregrams were analysed by matching spot positions from three independent replications. Results. The proteomes of albumins, globulins and legumin and vicilin fractions of globulins produced up to several hundred spots (proteins. Spots most characteristic of a given fraction were identified by computer analysis and spot matching. The albumin proteome accumulated spots of relatively high intensity over a broad range of pi values of -4.2-8.1 in 3 molecular weight (MW ranges: I - high molecular-weight albumins with MW of -50-110 kDa, II - average molecular-weight albumins with MW of -20-35 kDa, and III - low molecular-weight albumins with MW of -13-17 kDa. 2D gel electrophoregrams revealed the presence of 81 characteristic spots, including 24 characteristic of legumin and 14 - of vicilin. Conclusions. Two-dimensional gel electrophoresis proved to be a useful tool for

    The cobalt 60 radiolytic degradation products have been identified in the following corticosteroids: cortisone, cortisone acetate, hydrocortisone, hydrocortisone acetate, hydrocortisone sodium succinate, isoflupredone acetate, methylprednisolone, methylprednisolone acetate, prednisolone, prednisolone acetate, and prednisone. Two major types of degradation processes have been identified: loss of the corticoid side chain on the D-ring to produce the C-17 ketone and conversion of the C-11 alcohol, if present, to the C-11 ketone. Minor degradation products derived from other changes affecting the side chain are also identified in several corticosteroids. These compounds are frequently associated in corticosteroids as process impurities or degradation compounds. No new radiolytic compounds unique to 60Co-irradiation have been found. The majority of corticosteroids have been shown to be stable to 60Co-irradiation. The rates of radiolytic degradation ranged from 0.2 to 1.4%/Mrad.

    2009-07-01

    Reproduction in vertebrates is controlled by the Hypothalamus-Pituitary-Gonad axis and the main hormone actions have been extensively described. Still, despite the scattered information in fish, accumulating evidence strongly indicates that corticosteroids play essential roles in reproductive mechanisms. An integrative approach is important for understanding these implications. Animal husbandry and physiological studies at molecular to organismal levels have revealed that these corticosteroids are regulators of fish reproductive processes. But their involvements appear strongly contrasted. Indeed, for both sexes, corticosteroids present either deleterious or positive effects on fish reproduction. In this review, the authors will attempt to gather and clarify the available information about these physiological involvements. The authors will also suggest future ways to prospect corticosteroid roles in fish reproduction.

    Plantar fasciitis is commonly treated with corticosteroid injections to decrease pain and inflammation. Therapeutic benefits often vary in terms of efficacy and duration. Rupture of the plantar fascia has been reported as a possible complication following corticosteroid injection. A retrospective chart review of 120 patients who received corticosteroid injection for plantar fasciitis was performed at the authors' institution to determine the incidence of plantar fascia rupture. The plantar fascia rupture was diagnosed clinically and confirmed with magnetic resonance imaging. Various factors were analyzed, including the number of injections, interval between injections, body mass index (BMI), and activity level. Four patients (2.4%) consequently experienced plantar fascia rupture following an average of 2.67 injections. The average BMI of these patients was 38.6 kg/m². The authors conclude that corticosteroid injection therapy appears to be a safe and effective form of nonoperative treatment with minimal complications and a relatively low incident of plantar fascia rupture.

    Despite a number of clinical trials there is still controversy about the role of corticosteroid therapy in acute respiratory distress syndrome (ARDS). In addition recent meta-analyses differed markedly in the conclusions. This review is intended to provide a short practical guide for the clinician. Based on the available literature, high-dose and pre-emptive administration of corticosteroids is hazardous and not indicated. A low-dose corticosteroid regime given for 4 weeks may potentially be helpful and can be considered in acute or unresolved ARDS in less than 14 days after onset of ARDS, if a close infection surveillance program is available, if neuromuscular blockade can be avoided and if a stepwise dose reduction of corticosteroids is performed. The total daily dose at the beginning of treatment should not exceed 2 mg/kg body weight (BW) methylprednisolone.

    Full Text Available Background: Misuse of topical corticosteroids is a widespread phenomenon among young people in India, especially women. The practice is associated with significant adverse effects and poor awareness of these effects among the general public. Aim: This study was conducted to examine the misuse and adverse effects of topical corticosteroids among the people in Bastar region in Chhattisgarh state of India. Materials and Methods: Data collected from patients presenting with at least one of the adverse effects of topical corticosteroids as the chief complaint, from November 2010 to October 2011. Results: Out of the 6723 new patients, 379 (5.63% had presented with misuse and adverse effects of topical corticosteroids, of whom 78.89% were females. More than 65% of the patients were in the age group 10-29 years. The main reason for using the topical corticosteroids was to lighten skin colour and treat melasma and suntan. Acne (37.99% and telangiectasia (18.99% were the most common adverse effects noted. Conclusions: Misuse of topical corticosteroids has a huge impact on dermatological practice, leading to a significant proportion of visits to the dermatologist. This hydra-headed problem needs multi-dimensional interventions, involving educational, legal and managerial approaches with cooperation from different sectors of society.

  8. Corticosteroid Receptors, Their Chaperones and Cochaperones: How Do They Modulate Adipogenesis?

    Directory of Open Access Journals (Sweden)

    Judith Toneatto

    2014-11-01

    Full Text Available It is well known that glucocorticoids and mineralocorticoids are part of the list of hormones that control adipogenesis as well as different aspects of the physiology of the adipose tissue. Their actions are mediated through their binding to the glucocorticoid and the mineralocorticoid receptors (GR and MR, respectively, in complex with heat shock proteins (Hsps and high molecular weight immunophilins (IMMs. Albeit many aspects of the molecular mechanism of the corticosteroid receptors are not fully elucidated yet, it was not until recently that the first evidences of the functional importance of Hsps and IMMs in the process of adipocyte differentiation have been described. Hsp90 and the high molecular weight IMM FKBP51 modulate GR and MR activity at multiple levels, that is, hormone binding affinity, their subcellular distribution, and the transcriptional status, among other aspects of the NR function. Interestingly, it has recently been described that Hsp90 and FKBP51 also participate in the control of PPARγ, a key transcription factor in the control of adipogenesis and the maintenance of the adipocyte phenotype. In addition, novel roles have been uncovered for FKBP51 in the organization of the nuclear architecture through its participation in the reorganization of the nuclear lamina and the control of the subnuclear distribution of GR. Thus, the aim of this review is to integrate and discuss the actual understanding of the role of corticosteroid receptors, their chaperones and cochaperones, in the process of adipocyte differentiation.

    The primary structure of amaranth 11S globulin (Ah11S) was engineered with the aim to improve its functional properties. Four continuous methionines were inserted in variable region V, obtaining the Ah11Sr+4M construction. Changes on protein structure and surface characteristics were analyzed in silico. Solubility and heat-induced gelation of recombinant amaranth 11S proglobulin (Ah11Sr and Ah11Sr+4M) were compared with the native protein (Ah11Sn) purified from amaranth seed flour. The Ah11Sr+4 M showed the highest surface hydrophobicity, but as consequence the solubility was reduced. At low ionic strength (μ = 0.2) and acidic pH (proteins Ah11Sr and Ah11Sr+4 M had the highest and lowest solubility values, respectively. All globulins samples formed gels at 90 °C and low ionic strength, but Ah11Sn produced the weakest and Ah11Sr the strongest gels. Differential scanning calorimetry analysis under gel forming conditions revealed only exothermic transitions for all amaranth 11S globulins analyzed. In conclusion, the 3D structure analysis has revealed interesting molecular features that could explain the thermal resistance and gel forming ability of amaranth 11S globulins. The incorporation of four continuous methionines in amaranth increased the hydrophobicity, and self-supporting gels formed had intermediate hardness between Ah11Sn and Ah11Sr. These functional properties could be used in the food industry for the development of new products based on amaranth proteins.

    Chronic rhinosinusitis may cause olfactory dysfunction and affects quality of life in patients. In a prospective study we investigated the effect of topical application of corticosteroids through pressure-pulsed inhalation as treatment option of chronic rhinosinusitis with olfactory disorder. Patients with sinonasal olfactory disorder according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EP3OS) were allocated to the new nasal inhalation therapy or a systemic corticosteroid therapy, each receiving a corticosteroid course of 12 days. 18 patients received topical corticosteroid pressure-pulsed inhalation (AMSA, Schumacher, Dausenau) and 15 systemic corticosteroid. Olfactory function was measured before and after treatment using the Threshold Discrimination Identification score (TDI score) and visual analogue scales. Lund Mackay score (LMS) was measured before starting treatment. Olfactory function (OF) increased from 17.5 ± 6.4 to 21 ± 7.9 TDI points (p treatment after 2 months. In the follow-up period of 6 months, the mean TDI score dropped to 20.0 ± 9.2 points (p = 0.01). There was no correlation between LMS and TDI. Treatment of chronic rhinosinusitis with pressure-pulsed inhalation was demonstrated to be effective. Multicenter investigations with large participant numbers are needed.

    The role of corticosteroids in the treatment of severe leptospirosis is unclear. The rationale for their use is that, in severe leptospirosis, there is a severe immunological response that is harmful to the host resulting in multi-organ dysfunction, which is potentially offset by the nonspecific immunosuppression of high dose steroids. We conducted a systematic review of studies that have assessed the use of high dose corticosteroids in patients with severe leptospirosis by searching MEDLINE and Scopus SciVerse without any language or time restrictions. We identified five studies, including one open randomized clinical trial, which had assessed the use of high dose steroids in severe leptospirosis. Four studies demonstrated a benefit of corticosteroids in treating severe disease with pulmonary involvement when administered early in the course of the disease, but these studies had several methodological constraints as highlighted in the text. Only the randomized controlled trial study showed that corticosteroids are ineffective and may increase the risk of nosocomial infections. There is no robust evidence to suggest that high dose corticosteroids are effective in severe leptospirosis, and a well-designed randomized clinical trial is needed to resolve this.

    Full Text Available Abstract Background There are increased numbers of activated lymphocytes in the lungs of chronic obstructive pulmonary disease (COPD patients. The clinical benefits of corticosteroids in COPD patients are limited. Our hypothesis is that lymphocytes play a role in this corticosteroid insensitivity. Objectives To investigate the effects of the corticosteroid dexamethasone on lung lymphocyte cytokine production from patients with COPD compared to controls. Methods Cultured airway lymphocytes obtained by bronchoscopy from healthy non-smokers (HNS, smokers (S and COPD patients were stimulated with phytohaemagglutinin (PHA & phorbol myristate acetate (PMA, +/- dexamethasone. Supernatants were assayed for interleukin (IL-2 and interferon (IFNγ. Immunofluoresence was used to analyse changes in CD8 glucocorticoid receptor (GRα and GRβ expression. Results The inhibition of PHA/PMA stimulated IFNγ production by dexamethasone was reduced in COPD patients compared to HNS (p p Conclusions IFNγ production from COPD airway lymphocytes is corticosteroid insensitive. This phenomenon may be important in the poor clinical response often observed with corticosteroids.

    2009-07-01

    Full Text Available Abstract Background Exposure to dietary wheat proteins in genetically susceptible individuals has been associated with increased risk for the development of Type 1 diabetes (T1D. Recently, a wheat protein encoded by cDNA WP5212 has been shown to be antigenic in mice, rats and humans with autoimmune T1D. To investigate the genomic origin of the identified wheat protein cDNA, a hexaploid wheat genomic library from Glenlea cultivar was screened. Results Three unique wheat globulin genes, Glo-3A, Glo3-B and Glo-3C, were identified. We describe the genomic structure of these genes and their expression pattern in wheat seeds. The Glo-3A gene shared 99% identity with the cDNA of WP5212 at the nucleotide and deduced amino acid level, indicating that we have identified the gene(s encoding wheat protein WP5212. Southern analysis revealed the presence of multiple copies of Glo-3-like sequences in all wheat samples, including hexaploid, tetraploid and diploid species wheat seed. Aleurone and embryo tissue specificity of WP5212 gene expression, suggested by promoter region analysis, which demonstrated an absence of endosperm specific cis elements, was confirmed by immunofluorescence microscopy using anti-WP5212 antibodies. Conclusion Taken together, the results indicate that a diverse group of globulins exists in wheat, some of which could be associated with the pathogenesis of T1D in some susceptible individuals. These data expand our knowledge of specific wheat globulins and will enable further elucidation of their role in wheat biology and human health.

    Full Text Available Berker Bakbak, Banu Turgut Ozturk, Sansal Gedik, Bengu Ekinci Koktekir, Saban Gonul Selcuk University Medical Faculty, Department of Ophthalmology, Konya, Turkey Abstract: A 56-year-old man noted a sudden decrease of vision in his right eye 4 hours after intramuscular triamcinolone acetonide (TA injection. A diagnosis of unilateral nonarteritic anterior ischemic optic neuropathy (NAION was made, and the patient was counseled to discontinue using TA. Examination for possible risk factors revealed controlled hypertension. Final visual acuity was finger counting at 1 m, and the optic disc was pale in his right eye. This is the first reported case of unilateral NAION that has occurred in a patient after intramuscular corticosteroid injection. Although a cause-and-effect relationship is difficult to prove, the short duration between the TA injection and the NAION is noteworthy. The history of corticosteroid injection should be questioned in cases with predisposing conditions such as hypertension. Keywords: ischemic optic neuropathy, corticosteroids, optic disc edema

    2012-03-01

    Full Text Available Pulmonary coccidioidomycosis is a common cause of community-acquired pneumonia in endemic areas of the southwestern United States. The clinical spectrum of this disease ranges from an asymptomatic presentation to severe disease with ARDS and hypoxemic respiratory failure. Despite evidence supporting the use of corticosteroids for severe pulmonary disease in other fungal infections, there is currently no established role for this therapy in coccidioidomycosis infections. Peripheral eosinophilia is a common feature of coccidioidomycosis; however, pulmonary eosinophilia is rarely reported. In the setting of pulmonary eosinophilia of other etiologies, corticosteroid therapy has been demonstrated to have a role in reducing the inflammatory response and leading to a more rapid resolution of hypoxemic respiratory failure. We report a case of a patient with primary pulmonary coccidioidomycosis complicated by severe pulmonary eosinophilia that demonstrated rapid improvement after the initiation of corticosteroid therapy.

    Effects of alpha 2u-globulin accumulating agents on alpha 2u-globulins in rat kidneys were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting analysis. Treatment of male animals with decalin (150 mg/kg), 2,2,4-trimethylpentane (50 mg/kg), isophorone (150 mg/kg), d-limonene (150 mg/kg) or 1,4-dichlorobenzene (150 mg/kg) by gavage for 14 consecutive days in each case resulted in a marked intensification of a protein band corresponding to kidney-type-alpha 2u-globulin, with a molecular mass calculated to be approximately 16 kDa. However, intraperitoneal treatment with leupeptin and E-64 (two times 0.07 mmol/kg, for each), well known cystein protease inhibitors, while only slightly increasing this kidney-type-alpha 2u-globulin band, caused the intensification of a approximately 19-kDa molecular mass protein band which was revealed to be a native-type-alpha 2u-globulin by SDS-PAGE and immunoblotting. These results indicated that at least two types of alpha 2u-globulin can be increased in male rat kidney by chemical treatment. Moreover, cystein protease(s) appear(s) to play an important role in the degradation of alpha 2u-globulin and particularly in the conversion of native-type-alpha 2u-globulin to kidney-type-alpha 2u-globulin in rat kidneys.

The pathophysiological basis for the development of severe dengue, characterized by plasma leakage and the “shock syndrome” are poorly understood. No specific treatment or vaccine is available, and careful monitoring and judicious administration of fluids forms the mainstay of management at present. It is postulated that vascular endothelial dysfunction, induced by cytokine and chemical mediators, is an important mechanism of plasma leakage. Although corticosteroids are potent modulators of the immune system, their role in pharmacological doses in modulating the purported immunological effects that take place in severe dengue has been a subject of controversy. The key evidence related to the role of corticosteroids for various manifestations of dengue are reviewed here. In summary, there is currently no high-quality evidence supporting the beneficial effects of corticosteroids for treatment of shock, prevention of serious complications, or increasing platelet counts. Non-randomized trials of corticosteroids given as rescue medication for severe shock have shown possible benefit. Nonetheless, the evidence base is small, and good-quality trials are lacking. We reiterate the need for well-designed and adequately powered randomized controlled trials of corticosteroids for the treatment of dengue shock.Keywords: dengue, dengue shock, shock, corticosteroids, vascular leak, thrombocytopenia

  1. Lower corticosteroid skin blanching response is associated with severe COPD.

    Directory of Open Access Journals (Sweden)

    Susan J M Hoonhorst

    Full Text Available BACKGROUND: Chronic obstructive pulmonary disease (COPD is characterized by chronic airflow limitation caused by ongoing inflammatory and remodeling processes of the airways and lung tissue. Inflammation can be targeted by corticosteroids. However, airway inflammation is generally less responsive to steroids in COPD than in asthma. The underlying mechanisms are yet unclear. This study aimed to assess whether skin corticosteroid insensitivity is associated with COPD and COPD severity using the corticosteroid skin blanching test. METHODS: COPD patients GOLD stage I-IV (n = 27, 24, 22, and 16 respectively and healthy never-smokers and smokers (n = 28 and 56 respectively were included. Corticosteroid sensitivity was assessed by the corticosteroid skin blanching test. Budesonide was applied in 8 logarithmically increasing concentrations (0-100 μg/ml on subject's forearm. Assessment of blanching was performed after 7 hours using a 7-point scale (normal skin to intense blanching. All subjects performed spirometry and body plethysmography. RESULTS: Both GOLD III and GOLD IV COPD patients showed significantly lower skin blanching responses than healthy never-smokers and smokers, GOLD I, and GOLD II patients. Their area under the dose-response curve values of the skin blanching response were 586 and 243 vs. 1560, 1154, 1380, and 1309 respectively, p<0.05. Lower FEV1 levels and higher RV/TLC ratios were significantly associated with lower skin blanching responses (p = 0.001 and p = 0.004 respectively. GOLD stage I, II, III and IV patients had similar age and packyears. CONCLUSIONS: In this study, severe and very severe COPD patients had lower skin corticosteroid sensitivity than mild and moderate COPD patients and non-COPD controls with comparable age and packyears. Our findings together suggest that the reduced skin blanching response fits with a subgroup of COPD patients that has an early-onset COPD phenotype.

    To determine the most effective route of administration of corticosteroids in the treatment of ocular surface disease, by characterizing the difference between oral prednisolone and topical dexamethasone administration using an animal model. Pharmacokinetic analyses determined the corticosteroid concentrations in the normal ocular tissues of rabbits after oral or topical administration of corticosteroids using LC-MS/MS. In wound healing analyses, the area of the epithelial defect created by keratectomy using a 6-mm trephine was calculated with an image analyzer using an orally or topically steroid-administrated animal model. The average size of basal epithelial cells, the frequency of mitotic basal epithelial cells, the number of squamous cells, and the number of hypertrophic stromal fibroblasts were determined in the enucleated corneal tissues after wound closure. By slit lamp examination, no remarkable differences were observed between orally and topically administered groups. Pharmacokinetic analyses showed that the distribution of dexamethasone after topical administration was superior to that after oral administration in the cornea. In contrast, both concentrations of corticosteroid applied topically and orally were similar with regards to AUCs (area under the concentration-time curve) in the conjunctiva. Although the healing rate was slower in the topical group, all corneas were almost healed within 96 h in the wound healing analysis. According to the histological analyses of epithelial cells, the average basal cell size was larger, the frequency of mitotic basal cells was greater, and the number of squamous epithelial cell layers was lower in the topically administered group although all of these differences were with no statistical significance. However, the number of hypertrophic stromal fibroblasts in the topically administered group was significantly lower than that in the orally administered group. There are different distributions and effects between

    Abstract Background: Primary adhesive capsulitis is mainly characterized by spontaneous chronic shoulder pain and the gradual loss of shoulder motion. The main treatment for adhesive capsulitis is a trial of conservative therapies, including analgesia, exercise, physiotherapy, oral nonsteroidal anti-inflammation drugs, and intra-articular corticosteroid injections. Previously, it was reported that intra-articular corticosteroid lead to fast pain relief and improvement of range of motion (ROM). The objective of this study was to determine whether corticosteroid injections would lead to better pain relief and greater improvement in ROM. Methods: We searched PubMed, Medline, and the Cochrane library. We included 5 articles of the 1166 articles identified. Totally injection group included 115 patients and placebo group included 110 patients. We calculated the weighted mean differences to evaluate the pain relief as the primary outcome. We determined the ROM as the secondary outcome. Study quality was evaluated using the 12-item scale. We also used the criteria of the Grading of Recommendations Assessment, Development and Evaluation to evaluate the quality of evidence. Results: In total, 5 studies were included, 4 of which were randomized clinical trials, with a sample size of 225 patients with adhesive capsulitis of the shoulders. The overall pooled data demonstrated that, compared with placebo as control treatment, intra-articular corticosteroid injections were more effective in reducing the pain score at 0 to 8 weeks, but there was no difference between the injection group and the control group at 9 to 24 weeks. Improvement of ROM in the injection group was greater than that of the control group both at 0 to 8 and 9 to 24 weeks. Conclusions: Intra-articular corticosteroid injections were more effective in pain relief in the short term, but this pain relief did not sustain in the long term. Intra-articular corticosteroid injection resulted in greater improvement in

    ATP binding cassette transporters, P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), are expressed in skin, but their involvement in transdermal absorption of clinically used drugs remains unknown. Here, we examined their role in transdermal absorption of corticosteroids. Skin and plasma concentrations of dexamethasone after dermal application were reduced in P-gp and BCRP triple-knockout (Mdr1a/1b/Bcrp(-/-)) mice. The skin concentration in Mdr1a/1b/Bcrp(-/-) mice was reduced in the dermis, but not in the epidermis, indicating that functional expression of these transporters in skin is compartmentalized. Involvement of these transporters in dermal transport of dexamethasone was also supported by the observation of a higher epidermal concentration in Mdr1a/1b/Bcrp(-/-) than wild-type mice during intravenous infusion. Transdermal absorption after dermal application of prednisolone, but not methylprednisolone or ethinyl estradiol, was also lower in Mdr1a/1b/Bcrp(-/-) than in wild-type mice. Transport studies in epithelial cell lines transfected with P-gp or BCRP showed that dexamethasone and prednisolone are substrates of P-gp, but are minimally transported by BCRP. Thus, our findings suggest that P-gp is involved in transdermal absorption of at least some corticosteroids in vivo. P-gp might be available as a target for inhibition in order to deliver topically applied drugs and cosmetics in a manner that minimizes systemic exposure.

    Full Text Available BACKGROUND:Early recovery is an important factor for people undergoing facial plastic. However, the normal inflammatory processes that are a consequence of surgery commonly cause oedema (swelling and ecchymosis (bruising, which are undesirable complications. Severe oedema and ecchymosis delay full recovery, and may make patients dissatisfied with procedures. Perioperative corticosteroids have been used in facial plastic surgery with the aim of preventing oedema and ecchymosis.OBJECTIVES:To determine the effects, including safety, of perioperative administration of corticosteroids for preventing complications following facial plastic surgery in adults.METHODS:Search strategy: In January 2014, we searched the following electronic databases: the Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL (The Cochrane Library; Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations; Ovid Embase; EBSCO CINAHL; and Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS. There were no restrictions on the basis of date or language of publication. Selection criteria: We included RCTs that compared the administration of perioperative systemic corticosteroids with another intervention, no intervention or placebo in facial plastic surgery. ata collection and analysis: Two review authors independently screened the trials for inclusion in the review, appraised trial quality and extracted data.MAIN RESULTS: We included 10 trials, with a total of 422 participants, that addressed two of the outcomes of interest to this review: swelling (oedema and bruising (ecchymosis. Nine studies on rhinoplasty used a variety of different types, and doses, of corticosteroids. Overall, the results of the included studies showed that there is some evidence that perioperative administration of corticosteroids decreases formation of oedema over the first two postoperative days.

    Both linear and conformational epitopes likely contribute to the allergenicity of tree nut allergens, yet, due largely to technical issues, few conformational epitopes have been characterized. Using the well studied recombinant cashew allergen, Ana o 2, an 11S globulin or legumin, we identified a murine monoclonal antibody which recognizes a conformational epitope and competes with patient IgE Ana o 2-reactive antibodies. This epitope is expressed on the large subunit of Ana o 2, but only when associated with an 11S globulin small subunit. Both Ana o 2 and the homologous soybean Gly m 6 small subunits can foster epitope expression, even when the natural N-terminal to C-terminal subunit order is reversed in chimeric molecules. The epitope, which is also expressed on native Ana o 2, is readily susceptible to destruction by physical and chemical denaturants.

    Full Text Available Aflatoxins were conjugated with soy 11S globulins acid subunits and the hapten-specific monoclonal antibodies (McAbs cross-reactive with four major aflatoxins were achieved using indirect competitive ELISA screening procedure. The two antibodies (clones 1B2 and 2D3 had similar reaction efficiency with aflatoxins B1, B2, and G1 but showed a weak cross-reaction to G2. The clone 4C5 exhibited the highest sensitivity for all four aflatoxins. The concentrations of aflatoxins B1, B2, G1, and G2 at 50% inhibition for 4C5 were 1.1, 1.2, 2.1, and 17.6 pg mL−1. The results indicated that soy 11S globulin acid subunits were suitable novel carriers for aflatoxin antigen in immunization experiments and clone 4C5 could be used for simultaneous analysis of total aflatoxins.

    Full Text Available Introduction. Henoch-Schönlein purpura (HSP is the most common vascular disease of childhood. It is a multisystem disease most commonly affecting the skin, joints, gastrointestinal tract, and kidneys, but other organs may be affected, too. Gastrointestinal involvement occurs in approximately 65-90% of patients, ranging from mild symptoms such as abdominal pain, nausea, and vomiting, to more severe manifestations such as gastrointestinal bleeding and intussusception. In most cases, HSP spontaneously resolves without treatment. The use of corticosteroids is controversial and usually reserved for severe systemic manifestations. Some authors suggest that the abdominal pain and gastrointestinal hemorrhage of HSP may respond to steroids, with some suggesting that there is a benefit in their use and describing a regimen. Case outline. This is a case report of HSP in a fourteen year-old boy with abdominal pain and hematemesis. Upper endoscopy showed an edematous and erythematous change in the body of the stomach and purpuric lesions in the duodenum, while multiple erosions were found in the antral area. Parenteral corticosteroid therapy with gastric acid secretion inhibitor administration led to regression of gastrointestinal symptoms on the seventh day, with relapses on the fourth and sixth day. Peroral administration of corticosteroids and gradual decrease of daily doses started on the eighth day of abdominal symptoms. New purpuric skin rashes appeared during six weeks. Conclusion. Corticosteroid therapy with gastric acid secretion inhibitors showed a positive effect in our patient with a severe form of HSP accompanied by abdominal pain and gastrointestinal hemorrhage. .

    Post transplantation constrictive bronchiolitis (PTCB) is the most common pulmonary complication among long-term survivors of allogeneic hematopoietic stem cell transplantation (HSCT). It is a late manifestation of GVHD. Its treatment with high-dose systemic corticosteroids and other immunosuppressive regimens is associated with multiple side effects. Topical corticosteroids are used for the treatment of other manifestations of GVHD to minimize these side effects. We conducted a retrospective analysis of a series of adult patients to evaluate the efficacy of high-dose inhaled corticosteroids in the treatment of PTCB. Seventeen patients with new-onset airflow obstruction were diagnosed with PTCB. Their forced expiratory volume in 1 s (FEV1) declined from a median of 84% (range, 56-119) before HSCT to 53% (26-82) after HSCT. All patients received inhaled fluticasone propionate 500-940 microg two times daily. Symptoms of airway obstruction improved and FEV1 stabilized 3-6 months after treatment. We conclude that high-dose inhaled corticosteroids may be effective in the treatment of PTCB and propose a plausible mechanism of its action. A prospective evaluation of its efficacy is warranted.

    Full Text Available Amebic colitis, caused by intestinal infection with the parasite, Entamoeba histolytica, is a common cause of diarrhea worldwide. Fulminant amebic colitis is the most devastating complication of this infection, associated with both high mortality and morbidity. We conducted a review of the English literature to describe cases of fulminant amebic colitis associated with exposure to corticosteroid medications in order to identify the risk factors for poor outcome and determine difficulties in diagnosis and treatment.Articles reporting severe and fulminant forms of amebic colitis between 1991 and 2016 were collected. 525 records were screened to identify 24 cases for qualitative analysis associated with corticosteroid use. Cases arose from areas of high endemicity or travel to such areas. Most cases (14 of 24, 58% were given corticosteroids for initially misdiagnosed colitis, mainly inflammatory bowel, resulting in rapid progression of disease. Nearly half of all cases underwent surgical intervention, and 25% of cases died, despite all patients eventually receiving treatment with metronidazole. The odds of death did not differ significantly by prior misdiagnosis, co-morbidities, bowel perforation or need for surgery.Infection with E. histolytica should be considered prior to the administration of corticosteroids, in particular for patients residing in endemic areas or those with appropriate travel history, especially prior to the diagnosis of inflammatory bowel disease. The development of preventative and treatment interventions are needed to improve outcomes of fulminant disease.

    2014-01-01

    This review addresses the current status of steroid therapies for hearing and vestibular disorders and how certain misconceptions may be undermining the efficacy in restoring normal ear function, both experimentally and clinically. Specific misconceptions addressed are that steroid therapy is not effective, steroid-responsive hearing loss proves an underlying inflammatory problem in the ear, and steroids only have application to the hearing disorders listed below. Glucocorticoid therapy for hearing and balance disorders has been employed for over 60 years. It is recommended in cases of sudden hearing loss, Meniére’s disease, immune-mediated hearing loss, and any vestibular dysfunction suspected of having an inflammatory etiology. The predominant steroids employed today are dexamethasone, prednisone, prednisolone, and methyl-prednisolone. In spite of years of use, little is known of the steroid responsive mechanisms in the ear that are influenced by glucocorticoid therapy. Furthermore, meta-analyses and clinical study reviews occasionally question whether steroids offer any benefit at all. Foremost in the minds of clinicians is the immune suppression and antiinflammatory functions of steroids because of their efficacy for autoimmune hearing loss. However, glucocorticoids have a strong binding affinity for the mineralocorticoid (aldosterone) and glucocorticoid receptors, both of which are prominent in the ear. Because the auditory and vestibular end organs require tightly regulated endolymph and perilymph fluids, this ion homeostasis role of the mineralocorticoid receptor cannot be overlooked in both normal and pathologic functions of the ear. The function of the glucocorticoid receptor is to provide anti-inflammatory and anti-apoptotic signals by mediating survival factors. PMID:23044978

    Several recent investigations have reported a decline of rat hippocampal corticosteroid-binding receptors (CSRs) with aging. This decline has been proposed to be an initial cause (through disinhibition) of the elevated adrenal steroid secretion that apparently occurs with aging; however, it could instead be an effect of corticoid elevation (through down-regulation). In order to assess the effects of age on CSR biosynthetic capacity in the absence of down-regulatory influences of endogenous corticoids, as well as to study aging changes in CSR plasticity, we examined the up-regulation of hippocampal CSR that follows adrenalectomy (ADX). The rat hippocampus contains at least two types of CSR binding and differential analysis of types I and II CSR was accomplished by selective displacement of [3H]corticosterone with RU-28362, a specific type II agonist. In young (3 months old) Fischer-344 rat hippocampus, up-regulation of type II binding above 2-day ADX baseline was present by 3-7 days and increased still further by 8-10 days post-ADX; type I CSR density did not change significantly between 1 and 10 days post-ADX. However, in aged (24-26 months old) rats, type II CSR up-regulation did not occur over the 10 day post-ADX period. Thus, the age-related impairment of type II up-regulation may reflect an intrinsic deficit in CSR biosynthesis or lability that is independent of the acute endogenous adrenal steroid environment.

    Understanding how structural features determine specific biological activities has often proved elusive. With over 161 000 steroid structures described, an algorithm able to predict activity from structural attributes would provide manifest benefits. Molecular simulations of a range of 35 corticosteroids show striking correlations between conformational mobility and biological specificity. Thus steroid ring A is important for glucocorticoid action, and is rigid in the most specific (and potent) examples, such as dexamethasone. By contrast, ring C conformation is important for the mineralocorticoids, and is rigid in aldosterone. Other steroids that are less specific, or have mixed functions, or none at all, are more flexible. One unexpected example is 11-deoxycorticosterone, which the methods predict (and our activity studies confirm) is not only a specific mineralocorticoid, but also has significant glucocorticoid activity. These methods may guide the design of new corticosteroid agonists and antagonists. They will also have application in other examples of ligand–receptor interactions. PMID:21613285

    The frequency of scabies is increasing in France. Crusted (or Norwegian) scabies is a very contagious form of scabies because of the huge number of mites in the skin. It is observed in patients suffering from immunodepression, motor or sensory deficiency, or mental retardation. The clinical presentation, except for the classic manifestation of scabies, is characterized by crusted lesions. Treatment is not easy and requires hospitalization. Topical corticosteroids are frequently used for children's dermatological diseases. Their long-term and inappropriate application in an infested scabies child can induce crusted scabies. We report on a case of an 8-year-old boy who developed crusted scabies induced by topical corticosteroid application. We discuss the therapeutic aspects of this severe form of scabies.

  11. Minimizing side effects of systemic corticosteroids in children

    Full Text Available Corticosteroids are potent drugs used in management of various inflammatory and autoimmune disorders. The antiinflammatory effects of corticosteroids cannot however be separated from their metabolic effects. Children are more vulnerable to their side effects, particularly the effects on growth, immunity and adrenal suppression. It is essential for the treating physician to be aware of the side effects and the measures to be taken to minimize them. A side effect that is unique to children is growth suppression, which is helped by alternate day treatment. Administration of small doses of prednisolone (10-15 mg/day or < 0.5 mg/kg/day single dose on alternate days, does not slow growth velocity significantly. The potency of dexamethasone and betamethasone in suppressing growth is nearly 18 times higher than that of prednisolone. There is some evidence that the administration of growth hormone can reverse these changes.

    Narcoleptic features developed in a young man with CNS sarcoidosis. This was associated with a structural lesion in the hypothalamus as demonstrated on CT scans of the head. The diagnosis of narcolepsy was established by compatible clinical history and the Multiple Sleep Latency Test. Treatment with high-dose corticosteroids was ineffective, but when the low-dose, whole-brain irradiation was added, complete resolution of the narcoleptic features ensued.

    Radiation therapy is commonly used for the treatment of lung cancer. However, radiation pneumonitis frequently occurs as a complication of the radiation therapy. Although corticosteroids are widely used for the treatment of radiation pneumonitis, they are not always effective. In this report, we used cycosporin A in the treatment of a patient suffering from steroid-refractory radiation pneumonitis. To our knowledge, this is the first report in which cyclosporin A was successfully used in the treatment of radiation pneumonitis. (author)

    A 24-year-old male patient with a severe aplastic anemia (SAA) was treated with equine-antilymphocyte globulin (ALG). As complication of this treatment he developed a severe heteroimmune hemolytic anemia mediated by anti-species pan-agglutinin antibodies present in ALG. In spite of the fact that ALG is absorbed with red-cell stroma and platelets to remove anti-erythrocyte and anti-platelet contaminating antibodies, often only partial absorption is achieved, and the remaining antibodies are passively acquired by the recipient. Neutropenia and especially thrombocytopenia are usual complications of this treatment, but it is also possible to detect anti-erythrocyte antibodies in the serum and on the red cells of those patients. However, the unusual severity of the hemolysis suffered by our patient, with a striking decrease of the hemoglobin levels (Fig. 1) can be ascribed to the administration of ALG at a time at which the hematocrit was close to normal as a result of the previous administration of anabolics. It is likely that in severely anemic patients, with a high transfusional demand, such a hemolytic episode may remain undetected. The patient acquired reactivity to the direct antiglobulin test, as well as the positive results of investigation of unexpected antibodies and compatibility testing can be accounted for by the fact that commercial antihuman globulin serum (AGS) contains antibodies reacting with a globulin component shared by human and horse sera. Neutralization of AGS with ALG administered to the patient removed those cross-reacting antibodies, making it possible to perform reliable transfusion compatibility testing and to rule out the eventual presence of hidden alloantibodies or warm autoantibodies. Neutralized Coombs serum maintained its human antiglobulin properties unaltered (Table 1).(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available István Ivancsó, Renáta Böcskei, Veronika Müller, Lilla Tamási Department of Pulmonology, Semmelweis University, Budapest, Hungary Abstract: Small airways disease plays an important role in the pathogenesis of asthma, but assessment of small airways impairment is not easy in everyday clinical practice. The small airways can be examined by several invasive and noninvasive methods, most of which can at present be used only in the experimental setting. Inhalers providing extrafine inhaled corticosteroid particle sizes may achieve sufficient deposition in the peripheral airways. Many studies have reported the beneficial effects of extrafine inhaled corticosteroids on inflammation, ie, on dysfunction in both the central and distal airways in asthmatics, and there are some data on asthma phenotypes in which the small airways seem to be affected more than in other phenotypes, including nocturnal asthma, severe steroid-dependent or difficult-to-treat asthma, asthma complicated by smoking, elderly asthmatic patients and/or patients with fixed airflow obstruction, and asthmatic children. The relevant randomized controlled clinical trials indicate that the efficacy of extrafine and nonextrafine inhaled corticosteroid formulations is similar in terms of primary endpoints, but there are certain clinically important endpoints for which the extrafine formulations show additional benefits.

    2010-08-01

    For women at risk of delivery before 34 weeks of gestation, administration of betamethasone or dexamethasone for 24 or 36 hours reduces neonatal morbidity and mortality. In a double-blind randomised trial involving 1858 pregnant women, who received either a single course of corticosteroids or multiple courses every 14 days, no statistically significant difference in the rates of mortality and respiratory morbidity were observed during the 28 first days of life. Newborns had decreased height, weight and head circumference in the group treated every 14 days. No difference in outcome was noted at 2 years among 1047 infants whose mothers had received a single course of betamethasone or weekly treatment up to 32 weeks of gestation. Similarly, no difference in outcome was observed among 556 children whose mothers had received an initial course of betamethasone followed by regular injections of either betamethasone or placebo. However, 6 children (2.9%) exposed to repeated maternal treatment developed cerebral palsy, versus only one of the children (0.5%) exposed to a single course, indicating that repeat courses of antenatal corticosteroids might have a detrimental effect. In practice, it seems prudent to only use a single course of corticosteroids in this setting.

    2013-01-01

    Full Text Available Corticosteroids have been used since the 50s as anti-inflammatory and immunosuppressive drugs for the treatment of several pathologies such as asthma, allergy, rheumatoid arthritis, and dermatological disorders. Corticosteroids have three principal mechanisms of action: 1 inhibit the synthesis of inflammatory proteins blocking NF-kB, 2 induce the expression of anti-inflammatory proteins by IkB and MAPK phosphatase I, and 3 inhibit 5-lipoxygenase and cyclooxygenase-2. The efficacy of glucocorticoids in alleviating inflammatory disorders results from the pleiotropic effects of the glucocorticoid receptors on multiple signaling pathways. However, they have adverse effects: Growth retardation in children, immunosuppression, hypertension, hyperglycemia, inhibition of wound repair, osteoporosis, metabolic disturbances, glaucoma, and cataracts. Less is known about psychiatric or side effects on central nervous system, as catatonia, decreased concentration, agitation, insomnia, and abnormal behaviors, which are also often underestimated in clinical practice. The aim of this review is to highlight the correlation between the administration of corticosteroids and CNS adverse effects, giving a useful guide for prescribers including a more careful assessment of risk factors and encourage the use of safer doses of this class of drugs.

    Clinical and experimental data indicate that long-term corticosteroid use leads to atrophy of the type 2 muscle fibers. The purpose of this study was to characterize and quantify the nature of muscle function in rheumatic disease patients who have been on long-term corticosteroid therapy. Quadriceps function (i.e., peak torque and power) in 19 patients (11 with rheumatoid arthritis, five with systemic lupus erythematosis, and 3 other) and 11 age- and activity-matched normal controls was measured with an isokinetic dynamometer (Cybex II), during four constant velocity movements. Power was significantly lower for the patients at all speeds. At the higher speeds the patients' deficit in power production increased as indicated by a difference in the slopes of power-velocity regression lines. Measures of peak torque could not be consistently used to differentiate the groups. Patients with rheumatic diseases receiving corticosteroids have a decreased ability to generate muscle power. The method described allows for quantification of these deficits in a clinical setting.

    A 1-year-old boy developed autoimmune hemolytic anemia after a negative direct anti-globulin test. The concentration of erythrocyte membrane-associated immunoglobulin G, determined using an immunoradiometric assay, correlated with disease activity. He was positive for cytomegalovirus (CMV) both serologically and by quantitative real-time polymerase chain reaction, indicating that his autoimmune hemolytic anemia was directly caused by CMV infection. Since anti-CMV immunoglobulin G was not absorbed by the patient's erythrocytes, cross-reaction between erythrocyte antigens and CMV was not likely a causative factor for hemolysis.

    Full Text Available Introduction: Preterm delivery is associated with an increased risk of newborn morbidity and mortality. Respiratory distress syndrome (RDS is the most common comorbidity. It has been proven that this syndrome can be prevented with the administration of antenatal corticosteroids to women at risk of preterm delivery, before 35 weeks of gestational age.Aim: To evaluate the risk factors, severity, co-morbidities, and mortality of RDS in newborns of less than 35 weeks of gestational age, with specific emphasis on the association between the elapsed time since the administration of the last dose of a full cycle of corticosteroids and the frequency and severity of RDS.Methods: This descriptive retrospective study includes all newborns of less than 35 weeks of gestational age, who were born at our center between January 1, 2012 and December 31, 2014 and admitted to Neonatal Intensive Care Unit (NICU. Newborns with major malformations, chromosomopathies, hydrops, congenital TORCH infection or outborns were excluded. RDS was diagnosed according to the criteria of the Update on the European Consensus Guidelines on the Management of Neonatal Respiratory Distress Syndrome in Preterm Infants (2013 and classified with a grade of I to III, in accord with radiographic results.Results: A total of 234 newborns were studied, of which 35.5% had RDS. Antenatal corticosteroids were used for 90.1% of all newborns. When adjusted to the severity of RDS, birth weight, gestational age, and vasopressor support were all predictive factors of newborn mortality. A ROC curve identified a cut-off of at most 10.5 hours between the last dose of a full cycle of corticosteroids and the delivery as higher risk of onset of RDS and another cut-off of at most 6.5 hours as higher risk of onset of moderate to severe RDS (sensitivity of 80.0% and 83.3%, respectively.Conclusion: The last dose of a full antenatal corticosteroids cycle must be given at least 10.5 hours prior to delivery to

The latest research approach related to substance abuse considers the role of plasma proteins in novel treatments of addiction. Since long-term consumption of opioids has some effects on liver function and plasma transfer systems, the present study was designed to determine the electrophoretic profile of plasma proteins in opiates-addict subjects. Materials and methods: In this cross-control study, the sample groups consisted of 42 opium consumers and 35 heroine dependents as case group and 35 non-addict volunteers as control group. The control group was matched with addicts for age and sex. Opioid consumption was confirmed by laboratory diagnostic tests on urine samples such as immunochromatography (RSA, rapidosis and complementary tests including liquid-solid column chromatography and thin layer chromatography (TLC. After blood collection and serum preparation, serum electrophoresis was performed. Data were presented as mean±SEM and analyzed by SPSS ver.11.5. The comparison of groups was done by using parametric tests and p<0.01 was considered as statistically significant. Results: There was no significant difference in the amounts of albumin, alpha-1-globulin, alpha-2-globulin and beta-globulin between groups. Gamma-globulin concentration was not significantly different between

Compared with other agents, the most benefit from rATG induction has been observed in renal transplant recipients at high immunologic risk for rejection. However, in special populations, such as pediatrics, the elderly, and hepatitis C-positive and human immunodeficiency virus-positive renal transplant recipients, additional information is needed to delineate the absolute benefit of rATG induction compared with other induction agents. Selection of rATG as the choice of induction therapy in renal transplant recipients should be guided by a cost-effective approach in balancing efficacy, safety, and cost. This review summarizes the published literature on efficacy, safety, and cost of rATG induction in renal transplantation. Keywords: anti-thymocyte globulin, renal transplantation, induction therapy

    The protein contribution to the red blood cell (RBC) aggregation is studied using the in-house made two-channeled optical tweezers. The cells interaction was characterized using two forces: the force required for separating two cells (FD - disaggregating force) and the force required for holding them from their spontaneous aggregation (FA - aggregating force). The gamma globulin solutions with/without albumin were used to induce the RBC aggregation. The strong interaction (3-10 pN) between the cells was measured within the contact formed using optical tweezers. We found that FD becomes stronger as the gamma globulin concentration increases, while the addition of albumin to the solution led to the significant (few fold) enhancement of the cells interaction forces. However, despite of the strong interaction between the cells their spontaneous overlapping was not observed, unlike the case in plasma, where the cells did increase their overlapping surface, when attached with small interacting surface and released from optical traps. This work in addition to our previous work with model solutions of fibrinogen allows us to conclude that the synergy of blood components is one of the most important features that contribute to the reversible RBC aggregation.

    Purpose: To determine the frequency of inappropriate inhaled corticosteroid (ICS) therapy when it is prescribed concurrently with systemic corticosteroids; to identify cost-savings potential in the setting of chronic obstructive pulmonary disease (COPD) exacerbations. Methods: Patients admitted to 1 of 8 hospital locations utilizing an integrated electronic health record within the health system for COPD exacerbations treated with systemic corticosteroids (equivalent to at least 30 mg of oral prednisone) between July 1, 2013 and June 30, 2014 were included in a retrospective chart review. Endpoints assessed included number of ICS, with or without long-acting beta-2 agonists (LABA), respiratory medications potentially wasted due to overlap therapy with systemic corticosteroids, as well as overall cost attributed to drug product, administration products, and respiratory therapy labor cost from potentially inappropriate overlap therapy. Results were extrapolated based on the number of admissions within the specified time period. Length of stay data were also compared between the 2 groups (overlap therapy vs no overlap therapy) to determine whether overlap therapy results in a reduction of hospital stay. Results: A total of 10,710 admissions were identified and 74 charts were randomly identified for review. Forty-six (62%) patients received at least one dose of overlapping ICS or ICS/LABA. One hundred forty-two nebulized budesonide vials were wasted along with 43 ICS or ICS/LABA inhalers. A total cost of $8,152.75 was attributed to drug product, administration products, and labor cost. Extrapolating to the 10,710 admissions identified, there would potentially be 20,551 wasted budesonide vials and 6,223 wasted ICS or ICS/LABA inhalers, resulting in an estimated annual cost savings of $1,180,090.03 for the health system. Additionally, length of stay was shorter in the group not receiving overlap therapy compared to the group receiving overlap therapy, but it was not

    Full Text Available Fasciculations are characterized by visible subtle and fast contractions of muscle, even wormlike in movement, by the contraction of a fascicle of muscle fibers. The authors present the case study of a 28-year-old patient with the appearance of migratory and diffuse fasciculations with an onset after partial tapering off of oral corticosteroides (60 mg total dose indicated for treatment of Minimal change Glomerulopathy. Clinical Neurological physical exam allied with an ENMG, besides other complementary laboratory exams were used for screening the above-mentioned patient. Afterwards, current research relating to the topic at hand was made in order to update the data available in the Bireme, Scielo and PubMed Data Banks using the following key words: Fasciculation’s, motor neuron disease, and benign fasciculations in the Portuguese, English as well as Spanish language. Although fasciculation’s are most commonly associated with Motor neuron disease as well as with certain metabolic disorders, they may also be present in individuals with absolutely no underlying pathological disorders. In our case, fasciculation potentials that have been present for six months, with no other signs of a neurogenic disorder as well as absence of laboratory findings, the patient received a diagnosis of Benign Fasciculation Syndrome (BFS.We believe that the use of corticosteroides in high doses with subsequent tapering contributed to the fasciculation’s, especially due to the changes that this causes on the ionic channels. Fasciculation’s are symptoms seen in a large range of conditions, and also being the main symptom of the so-called Benign Fasciculation Syndrome. We have presented an example of this clinical syndrome in a patient whose complaint was fasciculation’s, with complete clinical remission of symptoms following complete tapering off of corticosteroid six months previously.

    Late preterm infants (34-36 weeks gestation) have a morbidity rate significantly higher than those born at term. However, few interventions have been undertaken to reduce this increased morbidity and mortality. Antenatal corticosteroid administration could be an effective preventive measure. The aim of this study was to describe the morbidity associated with late prematurity in our institution, and determine if there are differences between those who received antenatal corticosteroids. A prospective observational study was conducted on late preterm infants born in a tertiary hospital from October 2011 until September 2012. Two groups were formed according to whether or not they had received antenatal steroids. The rates of morbidity and mortality for each of the groups were analysed and compared. There was a total of 4127 live newborns during the study period, of whom 3795 were term and 332 were preterm (the overall prematurity rate was 8.04%). There were 247 late preterm deliveries, representing 6% of live born infants, and 74.4% of all premature infants. Of late preterm infants, 63.2% were admitted to the Neonatal Unit and 29.6% had received antenatal steroids. The incidence of admission to the Neonatal Unit and Neonatal Intensive Care, transient tachypnea, need for respiratory support in the form of continuous positive pressure airway and oxygen therapy, incidence of hypoglycemia, feeding difficulty, and jaundice requiring phototherapy were significantly higher (P<.05) in the late preterm group that did not receive antenatal steroids. Our finding suggests that the administration of antenatal corticosteroids to patients at risk of 34-36 weeks delivery could significantly reduce the cost and acute morbidity associated with late preterm birth.

    Cysticercosis is a disease caused by the larval stage of Taenia solium cestodes that belongs to the family Taeniidae that affects a number of hosts including humans. Taeniids tapeworms are hermaphroditic organisms that have reproductive units called proglottids that gradually mature to develop testis and ovaries. Cysticerci, the larval stage of these parasites synthesize steroids. To our knowledge there is no information about the capacity of T. solium tapeworms to metabolize progesterone or other precursors to steroid hormones. Therefore, the aim of this paper was to investigate if T. solium tapeworms were able to transform steroid precursors to corticosteroids and sex steroids. T. solium tapeworms were recovered from the intestine of golden hamsters that had been orally infected with cysticerci. The worms were cultured in the presence of tritiated progesterone or androstenedione. At the end of the experiments the culture media were analyzed by thin layer chromatography. The experiments described here showed that small amounts of testosterone were synthesized from (3)H-progesterone by complete or segmented tapeworms whereas the incubation of segmented tapeworms with (3)H-androstenedione, instead of (3)H-progesterone, improved their capacity to synthesize testosterone. In addition, the incubation of the parasites with (3)H-progesterone yielded corticosteroids, mainly deoxicorticosterone (DOC) and 11-deoxicortisol. In summary, the results described here, demonstrate that T. solium tapeworms synthesize corticosteroid and sex steroid like metabolites. The capacity of T. solium tapeworms to synthesize steroid hormones may contribute to the physiological functions of the parasite and also to their interaction with the host.

    In vitro dialysability of iron, zinc and protein was determined from whole bean (Phaseolus vulgaris), albumin and globulin (G1, G2) after cooking. Albumin showed the highest iron, zinc, protein and phytic acid content. Cooking increased iron and protein dialysability only in whole bean and albumin. Compared to globulins, albumin also presented a higher in vitro protein digestibility and cystine chemical reactivity. HPLC analysis of peptides in dialysates of bean and protein fractions suggested that some aggregation occurred during dialysis. The percentage of amino acids in dialysed peptides was found to be different between albumin and globulins. The difference in iron and zinc dialysability between albumin and globulins seems to depend on the phytic acid content of the albumin fraction and the protein properties of globulins.

    Superoxide anion production by liver microsomes from intact, adrenalectomized, and cortisoltreated adrenalectomized rats has been determined. The amount formed was roughly proportionate to the amount of cortisol given, and a similar response was seen in the activity of NADPH-cytochrome c reductase. The amount of measurable superoxide anion was markedly reduced by the addition of superoxide dismutase. The increased production of this potent free radical with cortisol therapy suggests that its formation may contribute to some of the harmful effects of corticosteroids given in more than physiologic amounts.

    Question Acute pyelonephritis in children is of great concern and I usually refer these patients to a pediatrician or send them to the emergency department owing to the risk of renal scarring. Are steroids an acceptable treatment to reduce risk of scarring? Answer Several agents have been studied in an effort to prevent renal scar formation following acute pyelonephritis in children. Use of corticosteroids, in conjunction with standard therapy for acute pyelonephritis, shows promising findings. However, evidence is very limited and steroids should not be offered on a regular basis as part of treatment. Copyright© the College of Family Physicians of Canada.

    Corticosteroids have been proved to be ineffective for Guillain-Barré syndrome, but the mechanism remains unknown. In a rabbit model of axonal Guillain-Barré syndrome, treatment with corticosteroids significantly reduced macrophage infiltration in the spinal ventral roots and the survival rate as well as clinical improvement. On 30th day after onset, there was significantly higher frequency of axonal degeneration in the corticosteroids-treated rabbits than saline-treated rabbits. Corticostero...

    The purpose of this study was to examine the prognostic impact of corticosteroids in hemodynamically stabile Staphylococcus aureus bacteremia (SAB). There were 361 hemodynamically stabile methicillin-sensitive SAB patients with prospective follow-up and grouping according to time-point, dose and indication for corticosteroid therapy. To enable analyses without external interfering corticosteroid therapy all patients with corticosteroid therapy equivalent to prednisone >10 mg/day for ≥1 month prior to positive blood culture results were excluded. Twenty-five percent (92) of patients received corticosteroid therapy of which 11 % (40) had therapy initiated within 1 week (early initiation) and 9 % (31) had therapy initiated 2-4 weeks after (delayed initiation) positive blood culture. Twenty-one patients (6 %) had corticosteroid initiated after 4 weeks and were not included in the analyses. A total of 55 % (51/92) received a weekly prednisone dose >100 mg. Patients with early initiated corticosteroid therapy had higher mortality compared to patients treated without corticosteroid therapy at 28 days (20 % vs. 7 %) (OR, 3.11; 95%CI, 1.27-7.65; p corticosteroid therapy predicted 28-day (HR, 3.75; 95%CI, 1.60-8.79; p = 0.002) and 90-day (HR, 3.10; 95%CI, 1.50-6.39; p = 0.002) mortality in Cox proportional hazards regression analysis. When including only patients receiving early initiated corticosteroid therapy with prednisone ≥100 mg/week the negative prognostic impact on 28-day mortality was accentuated (HR 4.8, p = 0.001). Corticosteroid therapy initiation after 1 week of positive blood cultures had no independent prognostic impact. Early initiation of corticosteroid therapy may be associate to increased mortality in hemodynamically stabile SAB.

    Canada's per capita use of intravenous immune globulin (IVIG) grew by approximately 115% between 1998 and 2006, making Canada one of the world's highest per capita users of IVIG. It is believed that most of this growth is attributable to off-label usage. To help ensure IVIG use is in keeping with an evidence-based approach to the practice of medicine, the National Advisory Committee on Blood and Blood Products of Canada (NAC) and Canadian Blood Services convened a panel of national experts to develop an evidence-based practice guideline on the use of IVIG for hematologic conditions. The mandate of the expert panel was to review evidence regarding use of IVIG for 18 hematologic conditions and formulate recommendations on IVIG use for each. A panel of 13 clinical experts and 1 expert in practice guideline development met to review the evidence and reach consensus on the recommendations for the use of IVIG. The primary sources used by the panel were 3 recent evidence-based reviews. Recommendations were based on interpretation of the available evidence and where evidence was lacking, consensus of expert clinical opinion. A draft of the practice guideline was circulated to hematologists in Canada for feedback. The results of this process were reviewed by the expert panel, and modifications to the draft guideline were made where appropriate. This practice guideline will provide the NAC with a basis for making recommendations to provincial and territorial health ministries regarding IVIG use management. Specific recommendations for routine use of IVIG were made for 7 conditions including acquired red cell aplasia; acquired hypogammaglobulinemia (secondary to malignancy); fetal-neonatal alloimmune thrombocytopenia; hemolytic disease of the newborn; HIV-associated thrombocytopenia; idiopathic thrombocytopenic purpura; and posttransfusion purpura. Intravenous immune globulin was not recommended for use, except under certain life-threatening circumstances, for 8 conditions

    2015-05-01

    Full Text Available Objectives: The use of inhaled corticosteroids is the standard maintenance therapy in asthma therapy and as adjunct therapy in moderate to severe chronic obstructive pulmonary disease. A dose-related increase in fracture risk is associated with inhaled corticosteroid use; there is an inverse relationship between bone mineral density and duration and cumulative dose of inhaled corticosteroid. Adequate intake of calcium and vitamin D are cornerstones of osteoporosis prevention. The objectives are to assess whether the proportion of patients receiving inhaled corticosteroids are taking calcium and vitamin D; the association between long-term inhaled corticosteroid use and abnormal bone mineral density or fractures; and how many qualified patients received bone mineral density scans. Methods: Patients who filled a prescription for inhaled corticosteroids at selected community pharmacies across Alberta were recruited for a survey of their osteoporosis prevention activities. Results: A total of 256 patients from 12 community pharmacies were included. The average age was 60 ± 17.4 years with 65% female. There were 21%, 51%, and 28% of patients on high, medium, and low dose inhaled corticosteroids, respectively. Only 17% of patients >50 years old received recommended calcium and vitamin D supplementation and 87 (73% of the qualified patients received bone mineral density scan. Conclusion: Osteoporosis prevention in inhaled corticosteroid users is currently poorly addressed. More promotion is needed to raise pharmacist awareness of the risks of inhaled corticosteroids.

    Full Text Available This experiment was conducted to study the profile of total protein, albumin, and globulin concentrationson Ettawah crossbreed neonates after consuming various colostrums. Twenty four healthy neonatal kidswere used in this study. The neonates were divided into four groups. Each group received fresh maternal(goat colostrum, frozen-thawed bovine colostrum, bovine spray dried colostrum, and bovine powdercommercial colostrum, respectively. Colostrums were given at 10% of body weight directly after birth andfollowed by the same amount every 12 hours, for three days. The blood was taken from jugular vein at 0, 12,24, 48, 72, and 168 hours after birth to determine total protein, albumin, and globulin concentrations.Results of this study indicated that the serum total protein and globulin concentration increased andreached the peak at 24 hours after birth. Compared to the concentration at birth, the increase of totalprotein concentration were 62.77%, 59.26%, 48.05%, and 66.67% in fresh maternal (goat, frozen-thawedbovine, bovine spray dried, and commercial bovine colostrum, respectively. Serum globulin concentrationincreased 4.9, 4.4, 4.8, and 14.6 times in fresh matermnal goat, frozen-thawed bovine, spray dried, andcommercial bovine colostrums respectively, compared to the concentration at birth. In conclusion, theconsumption of various colostrums i.e. fresh maternal goat colostrums, bovine colostrums (frozen-thawed,spray dried and commercial colostrums would increase the concentration of blood total protein and globulin,which both reached the highest concentration at 24 h after birth.

    Objective. Obesity is a risk factor for hypogonadotropic hypogonadism in men. Weight loss has been shown to improve hypogonadism in obese men. This study evaluated the early changes in sex hormones profile after bariatric surgery. Methods. This is a prospective study including 29 morbidly obese men. Main outcomes were changes in serum levels of total testosterone (TT), free testosterone (cFT), SHBG, estradiol, adiponectin, and leptin at 1 and 6 months after surgery. Results. The mean age of patients was 31 ± 8 years and the mean BMI was 56.8 ± 11.7 kg/m2. Fifteen patients underwent Roux-en-Y gastric bypass and 14 patients underwent sleeve gastrectomy. At baseline, 22 patients (75.9%) had either low TT levels (<10.4 nmol/L) or low cFT levels (<225 pmol/L). Total testosterone and SHBG levels increased significantly at 1 month after surgery (p ≤ 0.001). At 6 months after surgery, TT and cFT increased significantly (p ≤ 0.001) and 22 patients (75.9%) had normalized TT and cFT levels. There were no changes in estradiol levels at either 1 month or 6 months after surgery. Conclusions. Increases in TT and SHBG levels occurred early at 1 month after bariatric surgery while improvements in cFT levels were observed at 6 months after bariatric surgery.

    Molecular self-assembly is emerging as a viable 'bottom-up' approach to build stable organic/inorganic nanometer-scale blocks. Herein, under the conditions of appropriate pH and ionic strength, soy globulin 7S or 11S were coprecipitated with hydroxyapatite (HAp) or aragonite (Arag), respectively, to fabricate two organic/inorganic hybrids: 7S/HAp and 11S/Arag. Results from high-resolution transmission electron microscopy show that the hybrids exhibit a nanosized core-shell structure with globulin monomer 7S or 11S as core and HAp or Arag as shells. 7S/HAp and 11S/Arag present a disk and hexagon shape, respectively. After calcinations, monodispersed HAp without support from globulins existed as nanospheres. It was revealed that the globulin as host induces the self-assembly and growth layer by layer of HAp or Arag nanocrystals. The factors of molecular recognition and surface potential definitely affected the size and shape of the hierarchical blocks. This work provided a novel pathway to controllably synthesize a wide variety of precise plant protein/biomineral hybrid biomaterials.

    2016-01-01

    Full Text Available Background. Oral mucocele is a common lesion resulting from an alteration of minor salivary glands due to mucus accumulation. Rapid appearance, specific location, history of trauma, bluish colour, and consistency help in the diagnosis. Conventional surgical removal is the treatment of choice but has several disadvantages like damage to adjacent ducts with further development of satellite lesions. Therefore, the present study was undertaken to evaluate the efficacy of intralesional corticosteroid injection (betamethasone as a nonsurgical treatment procedure in oral mucoceles. Material and Method. A total of 20 cases (males and females, 10–30 years of age with clinically diagnosed oral mucoceles were given 1 mL of betamethasone intralesionally. All the patients were examined after a period of 7, 14, and 21 days to evaluate the response of the lesion towards treatment and consequently given the 2nd, 3rd, 4th injections. If the lesion resolved after one or two injections, the treatment was discontinued. Results. Out of the 20 cases, 18 of them showed complete regression of the lesion whereas the remaining 2 cases showed decrease in size. All the patients received maximum of 4 consecutive shots in weekly interval. Conclusion. Intralesional corticosteroid therapy can be considered as the first choice in the treatment of oral mucoceles.

    2012-01-01

    Full Text Available Introduction. In spite of the wide usage of corticosteroids for the treatment of a plethora of diseases, sometimes they can induce immediate hypersensitivity reactions, which are however uncommon. Case Outline. We report a case of immediate allergic reaction induced by intravenous methylprednisolone given before operation for surgical repair of an arm contracture as a sequel of burns, which the child had tolerated a month before. Six weeks later the patient repeated the anaphylactic reaction during skin testing to methylprednisolone. In addition, basophile activation test with methylprednisolone (BAT was positive. Conclusion. This case report describes a patient who experienced intraoperative anaphylaxis and anaphylactic reaction induced by skin testing. This is the first report on induction of both anaphylactic reactions by methylprednisolone in the same child. Clinical findings, positive BAT and positive skin tests with methylprednisolone imply that the child developed type-I hypersensitivity. The lack of cross-reactivity with other corticosteroids emphasizes that the reactions were caused by the steroid molecule.

  14. Protective effect of corticosteroids on radiation pneumonitis in mice

    Energy Technology Data Exchange (ETDEWEB)

    1988-01-01

    We explored the protective effect of corticosteroids on the mortality of mice that received thoracic irradiation. Methylprednisolone, 100 mg/kg/week, given from 11 weeks after gamma irradiation of the thorax resulted in an increase in the LD50 (11-26 weeks) from 14.3 +/- 0.3 (mean +/- SE) Gy to 17.6 +/- 0.4 Gy, P less than 0.001, a protection factor of 1.2. Withdrawal of steroids at various times during the period of radiation pneumonitis resulted in accelerated mortality in the next 2-4 weeks, so that the cumulative mortality caught up with that of control animals by 4 weeks after steroid withdrawal. However, after the end of the usual period of pneumonitis withdrawal of steroids did not result in accelerated mortality, suggesting that the time when steroids are protective corresponds to the duration of pneumonitis. A smaller dose of steroids, 25 mg/kg/week, was found to be as protective as the larger dose used in the above experiments. The possibility that corticosteroids reduce mortality, even when given many weeks after radiation, may have important practical and theoretical implications.

    Three different commercially available polyvalent immune globulins (IG) were investigated for the existence of antibodies against cell wall carbohydrates of four different E. faecalis serotypes (using a cell wall carbohydrate-enzyme-linked immunosorbent assay), and whether these antibodies mediated opsonic killing (using an opsonic-killing assay). All three IG preparations contained antibodies against all four serotypes (CPS-A to CPS-D). However, only one of the three IG preparations showed opsonic killing against all four serotypes. Average killing was higher against serotypes A and B (72 and 79 %, respectively) than against serotypes C and D (30 and 37 %, respectively). Such IG preparations could play a role as an adjuvant therapeutic option in life-threatening infections with E. faecalis, particularly when resistant strains are involved.

    2010-01-13

    The 11S globulin (legumin) gene family has been characterized in the castor plant Ricinus communis L. Phylogenetic analysis reveals the presence of two diverged subfamilies (RcLEG1 and RcLEG2) comprising a total of nine genes and two putative pseudogenes. The expression of castor legumin genes has been studied, indicating that it is seed specific and developmentally regulated, with a maximum at the stage when cellular endosperm reaches its full expansion (around 40-45 DAP). However, conspicuous differences are appreciated in the expression timing of individual genes. A characterization of the 5'-proximal regulatory regions for two genes, RcLEG1-1 and RcLEG2-1, representative of the two legumin subfamilies, has also been performed by fusion to the GUS reporter gene. The results obtained from heterologous expression in tobacco and transient expression in castor, indicating seed-specific regulation, support the possible utility of these promoters for biotechnological purposes.

    Background and Aims Corticosteroids are effective for the short-term treatment of inflammatory bowel disease (IBD). Long-term use, however, is associated with significant adverse effects. To define the: (1) frequency and duration of corticosteroid use, (2) frequency of escalation to corticosteroid-sparing therapy, (3) rate of complications related to corticosteroid use, (4) rate of appropriate bone density measurements (dual energy X-ray absorptiometry [DEXA] scans), and (5) factors associated with escalation and DEXA scans. Methods Retrospective review of Veterans Health Administration (VHA) data from 2002–2010. Results Of the 30,456 Veterans with IBD, 32% required at least one course of corticosteroids during the study time period, and 17% of the steroid users had a prolonged course. Among these patients, only 26.2% underwent escalation of therapy. Patients visiting a gastroenterology (GI) physician were significantly more likely to receive corticosteroid-sparing medications. Factors associated with corticosteroid-sparing medications included younger age (OR = 0.96 per year,95%CI:0.95, 0.97), male gender (OR = 2.00,95%CI:1.16,3.46), GI visit during the corticosteroid evaluation period (OR = 8.01,95%CI:5.85,10.95) and the use of continuous corticosteroids vs. intermittent corticosteroids (OR = 2.28,95%CI:1.33,3.90). Rates of complications per 1000 person-years after IBD diagnosis were higher among corticosteroid users (venous thromboembolism [VTE] 9.0%; fragility fracture 2.6%; Infections 54.3) than non-corticosteroid users (VTE 4.9%; fragility fracture 1.9%; Infections 26.9). DEXA scan utilization rates among corticosteroid users were only 7.8%. Conclusions Prolonged corticosteroid therapy for the treatment of IBD is common and is associated with significant harm to patients. Patients with prolonged use of corticosteroids for IBD should be referred to gastroenterology early and universal efforts to improve the delivery of high quality care should be undertaken

    Full Text Available To investigate the effect of the soy protein concentrate (CSP and 7S and 11S soy globulin on wheat dough and steamed bread (SB, mixing properties of the dough were assessed by farinograph and dynamic-mechanical analyzer (DMA. The quality attributes of SB were assessed by texture profile analyzer (TPA, sensory analysis, and scanning electron microscope (SEM. The results showed that CSP, 7S, or 11S (each from 2.0 to 4.0% significantly decreased gluten content (from 29.4 to 26.0, 36.7 to 31.8, and 31.6 to 30.7%, when those were added to wheat flour. The CSP/wheat dough stability was increased (from 6.5 to 8.4, 6.5 to 8.5, and 6.5 to 8.3 min and the degree of softening was decreased (from 71.0 to 68.0, 71.0 to 64.0, and 71.0 to 62.0 min, but 7S or 11S had the opposite result. Moreover, the ratio of 7S and 11S has a significant effect on the quality of the dough. The storage modulus and loss modulus of soy/wheat dough decreased in the order of CSP, control, 11S soy globulin, and 7S soy globulin. The hardness, chewiness, and cohesiveness of SB decreased in the order of control, CSP, 11S soy globulin, and 7S soy globulin. Microstructure demonstrated that gluten network was interfered by SPC, 7S, and 11S soy protein, which was in agreement with the texture analysis index. The quality of SB with 3% 11S was the best in texture, microstructure, and sensory. These findings indicate that 11S has the potential to be used as a special soy protein for SB making.

    Full Text Available Background: Corticosteroids are a group of commonly used drugs in dermatology practice whose non judicious use frequently results in undesirable and unwanted effects. Prescribing them rationally with care allows us to derive the maximum benefit out of them with minimal side effects. Methods: Retrospective analysis of 112 case files belonging to patients admitted in the department of dermatology over a period of one year was undertaken to ascertain the usage pattern of corticosteroids in relation to their potency, strength, frequency, duration, route, quantity to be applied. The data thus collected was expressed in terms of averages, ratios and proportions. Results: The total number of formulations prescribed were 929 out of which 10.8% were corticosteroids. The average number of formulations prescribed per patient was 8.29. About 78(70% patients admitted in dermatology received corticosteroids. Topical steroids were prescribed in 50 patients (44.7 % out of whom 36 (72% received only topical, the remaining 14(28% were prescribed both systemic and topical corticosteroids. Brand names were used in all cases. Highly potent corticosteroids like clobetasol, halobetasol and mometasone were prescribed to 39(50% of all cases who received topical corticosteroids. Conclusion: The study reveals the deficiencies which exist in the present prescribing pattern of corticosteroids. Educational interventions among the doctors as well as students should be carried out to in order to promote rational drug use. [Int J Basic Clin Pharmacol 2013; 2(4.000: 411-413

    Full Text Available Abstract Background Vitiligo is the most prevalent pigmentary disorder which occurs worldwide, with an incidence rate between 0.1-4 percent. It is anticipated that the discovery of biological pathways of vitiligo pathogenesis will provide novel therapeutic and prophylactic targets for future approaches to the treatment and prevention of vitiligo. The purposes of this study were evaluating the efficacy of supplemental zinc on the treatment of vitiligo. Methods This randomized clinical trial was conducted for a period of one year. Thirty five patients among 86 participants were eligible to entrance to the study. The patients in two equal randomized groups took topical corticosteroid and combination of oral zinc sulfate-topical corticosteroid. Results The mean of responses in the corticosteroid group and the zinc sulfate-corticosteroid combination group were 21.43% and 24.7%, respectively. Conclusion Although, the response to corticosteroid plus zinc sulfate was more than corticosteroid, there was no statistically significant difference between them. It appeared that more robust long-term randomized controlled trials on more patients, maybe with higher doses of zinc sulfate, are needed to fully establish the efficacy of oral zinc in management of vitiligo.

    The mechanisms by which corticosteroids reduce airway inflammation are not completely understood. Traditionally, corticosteroids were thought to inhibit cytokines exclusively at the transcriptional level. Our recent evidence, obtained in airway smooth muscle (ASM), no longer supports this view. We have found that corticosteroids do not act at the transcriptional level to reduce TNF-alpha-induced IL-6 gene expression. Rather, corticosteroids inhibit TNF-alpha-induced IL-6 secretion by reducing the stability of the IL-6 mRNA transcript. TNF-alpha-induced IL-6 mRNA decays at a significantly faster rate in ASM cells pretreated with the corticosteroid dexamethasone (t(1/2) = 2.4 h), compared to vehicle (t(1/2) = 9.0 h; P ASM cells.

    Full Text Available There are many local and systemic side-effects of topical corticosteroids. To the best of our Knowledge, Hidradenitis Supportive (HS due to topical corticosteroids has not been reported previously. We report a 39-year old, male patient who started himself a topical corticosteroid Pander Plus cream because of itching, scaly lesions over groins and buttocks since 6 months. After 4 months of topical treatment, he developed pus discharging sinuses over both groins and buttocks. Based on patient history, clinical and laboratory findings and the exclusion of other diagnoses, HS points out the use of topical corticosteroids. The case well highlights this unusual condition and represents the first case reported in India to our best of the knowledge. Having performed thorough literature search I would like to discuss in this report the evidence for this relation and stress the importance of appropriate usage of topical corticosteroids.

    The encephalopathy that occurs in association with hemolytic uremic syndrome (HUS), which is caused by enterohemorrhagic Escherichia coli (E. coli), has a high mortality rate and patients sometimes present sequelae. We herein describe the case of a 20-year-old woman who developed encephalopathy during the convalescent stage of HUS caused by E.coli O26. Hyperintense lesions were detected in the pons, basal ganglia, and cortex on diffusion-weighted brain MRI. From the onset of HUS encephalopathy, we treated the patient with methylprednisolone (mPSL) pulse therapy alone. Her condition improved, and she did not present sequelae. Our study shows that corticosteroids appear to be effective for the treatment of some patients with HUS encephalopathy.

    Full Text Available Oral corticosteroids (OCS play an integral role in the pharmacological management of asthma, as well as a number of other inflammatory and autoimmune disorders. However, although their broad spectrum of effect is beneficial in controlling inflammation, it can also lead to undesirable effects on other cells, resulting in adverse effects. The purpose of the present review is to discuss the particular benefits of OCS and to outline the optimal role of these agents in the management of asthma, drawing on evidence-based medicine and current clinical practice guidelines. The mandate for the present review also covers an analysis of the risk:benefit ratio as it pertains to OCS use in asthma. The more common adverse effects will be discussed and weighed against the possible benefits.

    Full Text Available In 1948 a corticosteroid compound was administered for the first time to a patient affected by rheumatoid arthritis by Philip Showalter Hench, a rheumatologist at the Mayo Clinic in Rochester, Minnesota (USA. He was investigating since 1929 the role of adrenal gland-derived substances in rheumatoid arthritis. For the discovery of cortisone and its applications in anti-rheumatic therapy, Hench, along with Edward Calvin Kendall and Tadeusz Reichstein, won the 1950 Nobel Prize for Medicine. In this review we summarize the main stages that led to the identification of the so-called compound E, which was used by Hench. We also consider the subsequent development of steroid therapy in rheumatic diseases, through the introduction of new molecules with less mineralocorticoid effects, such as prednisone, and more recently, deflazacort.

    It is a case study of a 62-yr-old female with crusted (Norwegian) scabies, which appeared during her treatment with systemic and topical corticosteroid therapy, under the diagnosis of erythroderma. In the same time, the patient had been suffered from hypothyoidism, and her skin changes were misdiagnosed, because it was thought that they are associated with her endocrine disorder. Suddenly, beside the erythema, her skin became hyperkeratotic, with widespread scaling over the trunk and limbs, and crusted lesions appeared on her scalp and ears. The microscopic examination of the skin scales with potassium hydroxide demonstrated numerous scabies mites and eggs. Repeated topical treatments with lindan, benzoyl benzoat and 10% precipitated sulphur ointment led to the complete resolution of her skin condition.

    Full Text Available Clinical manifestation of chronic rhinitis is due to local release of mediators from inflammatory cells. Eosinophil leukocytes are important in pathogenesis of nasal hypersensitivity as well as nasal hyperreactivity [1,2]. The aim of the study was to follow-up the effect of local corticosteroid treatment on a number of eosinophils in nasal secretion of patients with chronic rhinitis. The study was prospective and controlled. A total number of 88 subjects was included in the study. Patients with chronic rhinitis who were treated with local corticosteroids (63 constituted the experimental group (37 with isolated allergic rhinitis, 10 with isolated nonallergic noninfective hyperreactive rhinitis, 10 with allergic rhinitis associated with nasal polyposis and 6 with nonallergic noninfective hyperreactive rhinitis associated with nasal polyposis. There were 25 patients with chronic rhinitis in the control group (18 with iso- lated allergic rhinitis, 2 with isolated nonallergic noninfective hyperreactive rhinitis, 3 with allergic rhinitis associated with nasal polyposis, and 2 with nonallergic noninfective, hyperreactive rhinitis associated with nasal polyposis. During the treatment with beclomethasone dipropionate aqueous nasal spray (daily dose was 400 micrograms during 6 weeks for isolated rhinitis and 6 months for associated forms of rhinitis, control examinations were regularly performed. The first control was after one week the second after six weeks, the third after three months and the fourth after six months. The same control was carried out in the control group of patients who were without therapy. Cytological examination of nasal secretions included brush method of collecting secretions, staining smears with Leishman's stain and light microscopic scrutinising of nasal smear magnified up to 1000 times. The results of the study demonstrated the highly significant decrease in the number of eosinophils after the therapy in patients with isolated

    Both slowed growth in children and reduced bone mineral density (BMD) are systemic effects of corticosteroids, and there is concern about the degree to which these systemic effects affect growth and BMD. To engage in a data-driven discussion of the effects of inhaled corticosteroids (ICSs) on growth in children and BMD. Articles were selected based on their relevance to this review. Studies of ICSs in children in which growth was a secondary outcome have revealed slowed growth associated with low doses of budesonide, fluticasone propionate, and beclomethasone dipropionate. In the study of budesonide, the effect was permanent, and in the study of fluticasone propionate, the effect was long-lasting, but it is unclear whether the effect was permanent. However, the results of studies in which growth was the primary outcome were mixed. Slowed growth was detected in a study of beclomethasone dipropionate; however, slowed growth was not detected in a study of ciclesonide or flunisolide. A decrease in BMD acquisition in children was associated with high doses but not low to medium doses of ICSs. In adults, there was a dose-related effect of ICSs on BMD. Both higher daily dose and larger cumulative dose were associated with increased bone density loss. Because of the systemic effects on growth and bone health, children should be monitored for growth using stadiometry every 3 to 6 months and BMD should be monitored yearly in patients being treated with high doses of ICSs.

    1998-02-01

    From 1992 to 1995, 765 patients with a clinical diagnosis of plantar fasciitis were evaluated by one of the authors. Fifty-one patients were diagnosed with plantar fascia rupture, and 44 of these ruptures were associated with corticosteroid injection. The authors injected 122 of the 765 patients, resulting in 12 of the 44 plantar fascia ruptures. Subjective and objective evaluations were conducted through chart and radiographic review. Thirty-nine of these patients were evaluated at an average 27-month follow-up. Thirty patients (68%) reported a sudden onset of tearing at the heel, and 14 (32%) had a gradual onset of symptoms. In most cases the original heel pain was relieved by rupture. However, these patients subsequently developed new problems including longitudinal arch strain, lateral and dorsal midfoot strain, lateral plantar nerve dysfunction, stress fracture, hammertoe deformity, swelling, and/or antalgia. All patients exhibited diminished tension of the plantar fascia upon examination by the stretch test. Comparison of calcaneal pitch angles in the affected and uninvolved foot showed a statistically significant difference of 3.7 degrees (P = 0.0001). Treatment included NSAIDs, rest or cross-training, stretching, orthotics, and boot-brace immobilization. At an average 27-month follow-up, 50% had good/excellent scores and 50% had fair/poor scores. Recovery time was varied. Ten feet were asymptomatic by 6 months post rupture, four feet by 12 months post rupture, and 26 feet remained symptomatic 1 year post rupture. Our findings demonstrate that plantar fascia rupture after corticosteroid injection may result in long-term sequelae that are difficult to resolve.

    Although surgery can provide definitive treatment for de Quervain's tenosynovitis, nonoperative treatment could be preferable if symptoms are predictably relieved. We sought to determine the effectiveness of corticosteroid injections as treatment for de Quervain's tenosynovitis and to evaluate patient characteristics as predictors of treatment outcome. A retrospective study was conducted using our institutional database International Classification of Disease, version 9 (ICD-9) code list for de Quervain's tenosynovitis. Treatment success was defined as relief of symptoms after 1 or 2 injections. Relief was defined as resolution or improvement to the extent that the patient did not seek further intervention. Failure was defined as a subsequent surgical release or a third injection. Logistic regression analyses were performed to look for univariate associations between patient demographics/comorbidities and risk of treatment failure. The treatment outcome of 222 limbs from 199 patients was studied. Of the 222 limbs, 73.4% (95% confidence interval [CI], 66.9%-79.1%) experienced treatment success within 2 injections, and 51.8% (95% CI, 45.0%-58.6%) experienced success after 1 injection. Body mass index (BMI) >30 and female sex were found to be significantly associated with treatment failure, with a 2.4-fold increase (95% CI, 1.02%-5.72%) in odds and 3.23 times greater (95% CI, 1.08%-9.67%) odds of failure, respectively. Although not reaching statistical significance, African American race, hypothyroidism, and carpal tunnel syndrome suggested increased odds of failure. This study indicates that corticosteroid injections are a useful treatment for de Quervain's tenosynovitis, leading to treatment success 73.4% of the time within 2 injections. This study also suggests that female sex and BMI >30 are associated with increased treatment failure.

    Background Single nucleotide polymorphisms (SNPs) influence a patient's response to inhaled corticosteroids and β2-agonists, and the effect of treatment with inhaled corticosteroids is synergistic with the effect of β2-agonists. We hypothesized that use of inhaled corticosteroids could influence the effect of SNPs associated with bronchodilator response. Objective To assess whether, among asthma subjects, the association of SNPs with bronchodilator response is different between those treated with inhaled corticosteroids vs. those on placebo. Methods A genome-wide association analysis was conducted using 581 white subjects from the Childhood Asthma Management Program (CAMP). Using data for 449,540 SNPs, we conducted a gene by environment analysis in PLINK with inhaled corticosteroid treatment as the environmental exposure and bronchodilator response as the outcome measure. We attempted to replicate the top 12 SNPs in the Leukotriene Modifier Or Corticosteroid or Corticosteroid-Salmeterol (LOCCS) Trial. Results The combined P-value for the CAMP and LOCCS populations was 4.81E-08 for rs3752120, which is located in the zinc finger protein gene ZNF432, and has unknown function. Conclusions Inhaled corticosteroids appear to modulate the association of bronchodilator response with variant(s) in the ZNF432 gene among adults and children with asthma. Clinical Implications Clinicians who treat asthma patients with inhaled corticosteroids should be aware that the patient's genetic makeup likely influences response as measured in lung function. Capsule Summary Our study suggests that inhaled corticosteroids could influence the effect of multiple SNPs associated with bronchodilator response across the genome. PMID:24280104

    Severe graft-versus-host disease is a major barrier for non-T-cell-depleted haploidentical stem cell transplantation. There is no consensus on the optimal graft-versus-host disease prophylaxis. This study compared the two most commonly used graft-versus-host disease prophylaxis regimens (post-transplant cyclophosphamide-based vs. the anti-thymocyte globulin-based) in adults with acute myeloid leukemia reported to the European Society for Blood and Bone Marrow Transplantation. A total of 308 patients were analyzed; 193 received post-transplant cyclophosphamide-based regimen and 115 anti-thymocyte globulin-based regimen as anti-graft-versus-host disease prophylaxis. The post-transplant cyclophosphamide-based regimen was more likely to be associated to bone marrow as graft source (60% vs. 40%; P=0.01). Patients in the post-transplant cyclophosphamide-based regimen group had significantly less grade 3–4 acute graft-versus-host disease than those in the anti-thymocyte globulin-based group (5% vs. 12%, respectively; P=0.01), comparable to chronic graft-versus-host disease. Multivariate analysis showed that non-relapse mortality was lower in the post-transplant cyclophosphamide-based regimen group [22% vs. 30%, Hazard ratio (HR) 1.77(95%CI: 1.09–2.86); P=0.02] with no difference in relapse incidence. Patients receiving post-transplant cyclophosphamide-based regimen had better graft-versus-host disease-free, relapse-free survival [HR 1.45 (95%CI: 1.04–2.02); P=0.03] and leukemia-free survival [HR 1.48 (95%CI: 1.03–2.12); P=0.03] than those in the anti-thymocyte globulin-based group. In the multivariate analysis, there was also a trend for a higher overall survival [HR 1.43 (95%CI: 0.98–2.09); P=0.06] for post-transplant cyclophosphamide-based regimen versus the anti-thymocyte globulin-based group. Notably, center experience was also associated with non-relapse mortality and graft-versus-host disease-free, relapse-free survival. Haplo-SCT using a post

    Inhaled glucocorticoids, also know as corticosteroids (ICS), revolutionized the treatment of asthma by suppressing airways inflammation and ICS therapy now forms the basis of treatment of asthma of all severities. More recently and usually in combination with a long-acting β-agonist (LABA), ICS use has been established in the treatment of chronic obstructive pulmonary disease (COPD). In asthma, ICS improves asthma control, lung function and prevents exacerbations, including hospital admissions and probably decreases mortality. Similar effects are seen in COPD but to a much lesser degree, however, an improvement in symptoms such as breathlessness and reduction in exacerbations occur particularly in more advanced disease with ICS. Chronic inflammation is a feature of both asthma and COPD, although there are differences in the site and characteristics of the inflammatory response. ICS have proven to be less effective in patients with severe asthma, smoking asthmatics and in patients with COPD. ICS act by binding to and activating specific cytosolic receptors (GR), which then translocate to the nucleus where they regulate gene expression by either binding to DNA and inducing anti-inflammatory genes or by repressing the induction of pro-inflammatory mediators. GR is able to selective repress specific inflammatory genes by differing actions on specific intracellular signalling pathways and transcription factors such as nuclear factor κB and on kinases pathways. Abnormal activation of these pathways may result in glucocorticoid resistance. Although, ICS/LABA combinations will remain the main focus of treatment of airways diseases in the near future; other combinations that improve the efficacy of ICS by reducing the abnormal activation of pathways that cause glucocorticoid resistance will be developed.

  1. Oral and inhaled corticosteroids: Differences in P-glycoprotein (ABCB1) mediated efflux

    There is concern that P-glycoprotein mediated efflux contributes to steroid resistance. Therefore, this study examined bidirectional corticosteroid transport and induction capabilities for P-glycoprotein (P-gp) to understand which of the systemic and inhaled corticosteroids interacted with P-gp to the greatest extent. Hydrocortisone, prednisolone, prednisone, methylprednisolone, and dexamethasone represented systemically active drugs, while fluticasone propionate, beclomethasone dipropionate, ciclesonide and budesonide represented inhaled corticosteroids. Aldosterone and fludrocortisone represented mineralocorticoids. All drugs were detected using individually optimised HPLC protocols. Transport studies were conducted through Caco-2 monolayers. Hydrocortisone and aldosterone had efflux ratios below 1.5, while prednisone showed a P-gp mediated efflux ratio of only 1.8 compared to its active drug, prednisolone, with an efflux ratio of 4.5. Dexamethasone and beclomethasone had efflux ratios of 2.1 and 3.3 respectively, while this increased to 5.1 for methylprednisolone. Fluticasone showed an efflux ratio of 2.3. Protein expression studies suggested that all of the inhaled corticosteroids were able to induce P-gp expression, from 1.6 to 2 times control levels. Most of the systemic corticosteroids had higher passive permeability (> 20 × 10{sup −6} cm/s) compared to the inhaled corticosteroids (> 5 × 10{sup −6} cm/s), except for budesonide, with permeability similar to the systemic corticosteroids. Inhaled corticosteroids are not transported by P-gp to the same extent as systemic corticosteroids. However, they are able to induce P-gp production. Thus, inhaled corticosteroids may have greater interactions with other P-gp substrates, but P-gp itself is less likely to influence resistance to the drugs. -- Highlights: ► Inhaled corticosteroids are only weak substrates for P-gp, including budesonide. ► Inhaled corticosteroid potent P-gp inducers especially

    Corticosteroid-related adverse events (AEs) are commonly reported in systemic lupus erythematosus (SLE), but are often under-represented in claims data. The most common corticosteroid-related AEs are not necessarily the most costly. The present study aimed to examine corticosteroid-related AE rates and identify the associated cost consequences in patients with SLE from the perspective of rheumatologists treating SLE in the United States (US). A modified Delphi process and RAND Appropriateness Method was used to estimate corticosteroid-related AEs and costs based on data from SLE-treating US rheumatologists and estimates from alternative sources. The panel (n=10) participated in two web-based questionnaires, covering disease severity, corticosteroid use, corticosteroid-related AEs, and resource utilization associated with treatment of the AEs. Eight members of the panel then participated in a guided discussion by interactive teleconference, in which the costs associated with specific corticosteroid-related AEs were also discussed. Consensus was achieved in the teleconference when a single response category (consensus values from 1 to 4 [4=strongly agree, 1=strongly disagree]) accounted for ≥80% of responses. Thirteen consensus statements were developed following two Delphi rounds. Costs were estimated for eight corticosteroid-associated AEs from the panel of rheumatologists. In the patients with SLE treated by these physicians, 41.5% were considered to have mild disease, 36.5% moderate disease, and 22.0% severe disease. The number of specialist visits, corticosteroid use, and corticosteroid dose increased with disease severity. The estimated rates of all AEs (except for cataracts) were at least doubled in patients receiving corticosteroid doses>20 mg/day compared with ≤20 mg/day. The highest estimated mean total costs of an event (for the required treatment duration for one patient) were for avascular necrosis ($14,460) and serious infection ($11,660). The

    The content and globulin subunit composition of soybean proteins are known to affect tofu quality and food-grade soybeans usually have higher levels of proteins. We studied the tofu quality of soybeans with high (44.8%) or low (39.1%) protein content and with or without the 11S globulin polypeptide, 11SA4. Both protein content and 11SA4 significantly affected tofu gel properties. Soybeans containing more protein had smaller seeds which produced significantly firmer (0.663 vs.0.557 N, pprotein subunits, which may have contributed to the improvement in tofu gel properties. These results suggest that, in combination with higher protein content, certain protein subunits or their polypeptides can also be targeted in selecting soybeans to further improve soy food quality.

    The inflammatory myopathies consist of three distinct groups: dermatomyositis, polymyositis, and inclusion body myositis. Dermatomyositis is distinguished by its characteristic rash, while polymyositis is a diagnosis of exclusion. Inclusion body myositis is characterized by early involvement of distal muscle groups and the quadriceps. Definitive diagnosis is made by muscle biopsy, which demonstrates histological features characteristic for each disorder. Immune mechanisms play a role in the pathogenesis of the inflammatory myopathies. A complement-mediated microangiopathy is seen in dermatomyositis, while there is evidence for a T cell-mediated process in polymyositis and inclusion body myositis. Treatment with prednisone is helpful to a majority of patients for a period of time. Immunosuppressive drugs have met with limited success. We describe a group of patients with dermatomyositis, resistant to available therapies, whose muscle strength, skin changes, and muscle biopsies improved significantly during treatment with intravenous immune globulin. The treatment of polymyositis and inclusion body myositis with intravenous immune globulin is currently under study.

    Low albumin to globulin ratio has been found previously to have a high positive predictive value for feline infectious peritonitis (FIP) in cats with clinical signs highly suggestive of the disease. However, FIP can have a more vague clinical presentation. This retrospective study found that the positive predictive value of an albumin:globulin (A:G) ratio of <0.8 and <0.6 was only 12.5% and 25%, respectively, in a group of 100 cats with one or more clinical signs consistent with FIP. The negative predictive value was 100% and 99% for an A:G ratio of <0.8 and A:G<0.6%, respectively. Therefore, when the prevalence of FIP is low, the A:G ratio is useful to rule out FIP but is not helpful in making a positive diagnosis of FIP.

    Full Text Available Abstract Background Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography and benefit of pharmacological treatment is unclear. Although prophylactic use of corticosteroid for reduction of pancreatic injury after ERCP has been evaluated, discrepancy about beneficial effect of corticosteroid on pancreatic injury still exists. The aim of current study is to evaluate effectiveness and safety of corticosteroid in prophylaxis of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP. Methods We employed the method recommended by the Cochrane Collaboration to perform a meta-analysis of seven randomized controlled trials (RCTs of corticosteroid in prevention of post-ERCP pancreatitis (PEP around the world. Results Most of the seven RCTs were of high quality. When the RCTs were analyzed, odds ratios (OR for corticosteroid were 1.13 [95% CI (0.89~1.44, p = 0.32] for PEP, 1.61 [95% CI (0.74~3.52, p = 0.23] for severe PEP, 0.92 [95% CI (0.57~1.48, p = 0.73] for post-ERCP hyperamylasemia respectively. The results indicated that there were no beneficial effects of corticosteroid on acute pancreatitis and hyperamylasemia. No evidence of publication bias was found. Conclusion Corticosteroids cannot prevent pancreatic injury after ERCP. Therefore, their use in the prophylaxis of PEP is not recommended.

    Full Text Available Acute exogenous lipoid pneumonia is a rare disorder in adults. A treatment of choice for lipoid pneumonia has not been established, and systemic corticosteroid use remains controversial. We report the case of a 32-year-old man with schizophrenia who presented with kerosene-induced acute exogenous lipoid pneumonia that was treated with a systemic corticosteroid. In this case, supportive therapy did not improve the patient's condition, so systemic corticosteroid therapy was commenced four days after he ingested the kerosene. After corticosteroid commencement, the patient's symptoms and hypoxia improved within a few days. Although some radiological characteristics of this disorder have been reported previously, the process of radiological improvement of exogenous lipoid pneumonia is not well known. In this case, computed tomography findings changed dramatically after corticosteroid therapy was initiated. Extensive bilateral consolidations that were observed on admission improved. Although pneumatoceles developed two weeks after corticosteroid commencement, they were nearly gone after two months of the treatment. While corticosteroid therapy is not suitable for all cases, it should be considered for severe or refractory cases.

    Full Text Available The effects of various ionic strengths and protein concentrations on the fibrils structure and gel properties of rice bran globulin (RBG at pH 2.0 were investigated using atomic force microscopy (AFM, rheometer, and scanning electron microscope (SEM. AFM images showed the morphology of assembling RBG fibrils from strand beads to becoming branch clustered, when electrostatic repulsive forces attenuated gradually with increasing ionic strength. NaCl seems to accelerate the kinetics of fibrils formation, resulting in a significant increase in Th T fluorescence intensity. The increased ionic strengths promote particle size increasing and zeta potential decreasing synchronously. The percolation model G'~C-Cpn be used to calculate theoretical RBG gels concentration at various ionic strengths (0–500 mM, which decreased from 15.17 ± 0.63 to 2.26 ± 0.27 wt%. SEM images exhibited a granular mesh-like gel structure. A more homogenous structure occurred in low ionic strength. This study elucidates properties of RBG fibrils and gels as a bioactive material.

  14. Clinical benefits and immunopathological correlates of intravenous immune globulin in the treatment of inflammatory myopathies.

    Dalakas, M C

    1996-05-01

    High-dose intravenous immune globulin (IVIG) is emerging as a promising therapy for patients with inflammatory myopathies who have become unresponsive to, or cannot tolerate, conventional therapies. In a double-blind, placebo-controlled study, using objective criteria for improvement, IVIG demonstrated moderate to dramatic improvement in 75% of the patients with dermatomyositis. Preliminary results from a controlled study in inclusion-body myositis show that IVIG may also exert a mild benefit, but only in a small number of patients and in certain muscle groups. In some patients with polymyositis, IVIG is reported to be of benefit but controlled studies have not yet been completed. Immunocytochemical, immunological and in vitro studies on the patients' repeated muscle biopsies and follow-up sera showed that IVIG exerts its action in inflammatory myopathies by: (i) inhibiting myotoxic cytokines, such as TNF-alpha and IL-1; (ii) blockade of Fc receptors on endomysial macrophages interfering with Fc receptor-mediated phagocytosis; and (iii) inhibiting the uptake of C3 and intercepting the formation and deposition of membranolytic attack complex on the endomysial capillaries.

    Objective Impaired immunonutritional status has disadvantageous effects on outcomes for cancer patients. Preoperative albumin-to-globulin ratio (AGR) and the prognostic nutrition index (PNI) have been used as prognostic factors in various cancers. We aimed to evaluate the clinical significance of the AGR and PNI in glioblastoma. Materials and methods This retrospective analysis involved 166 patients. Demographic, clinical, and laboratory data were collected. AGR and the PNI were calculated as AGR = albumin/(total serum protein − albumin) and PNI = albumin (g/L) + 5 × total lymphocyte count (109/L). Overall survival (OS) was estimated by Kaplan–Meier analysis. Receiver-operating characteristic analysis was used to assess the predictive ability of AGR and the PNI. Cox proportional-hazard models estimating hazard ratios (HRs) and 95% confidence intervals (CIs) were used for univariable and multivariable survival analyses. Results The cutoff values of AGR and PNI were 1.75 and 48. OS was enhanced, with high AGR (>1.75) and the PNI (>48) (Pglioblastoma. AGR and the PNI could also help in developing good adjuvant-therapy schedules. PMID:28223828

    A yeast-recombinant hepatitis B vaccine was licensed recently by the Food and Drug administration and is now available. To assess the efficacy of the yeast-recombinant vaccine, the authors administered the vaccine in combination with hepatitis B immune globulin to high-risk newborns. If infants whose mothers were positive for both hepatitis B surface antigen and the e antigen receive no immunoprophylaxis, 70% to 90% become infected with the virus, and almost all become chronic carriers. Among infants in this study who received hepatitis B immune globulin at birth and three 5-/sup +/g doses of yeast-recombinant hepatitis B vaccine, only 4.8% became chronic carriers, a better than 90% level of protection and a rate that is comparable with that seen with immune globulin and plasma-derived hepatitis B vaccine. Hepatitis surface antigen and antibodies were detected by radioimmunoassay. These data suggest that, in this high-risk setting, the yeast-recombinant vaccine is as effective as the plasma-derived vaccine in preventing hepatitis B virus infection and the chronic carrier state.

    In this study, which was performed on a Dutch dairy goat farm, several aspects of the administration of colostrum to new-born goat kids were examined. Time of colostrum administration and amount and type of colostrum administered were compared. Effectiveness was measured as total serum protein content and gamma globulin fraction. No significant differences in serum gamma globulin titre were observed between kids that received colostrum at 30 or 60-90 minutes post partum, respectively. Titres were significantly lower in kids that received 100 ml of colostrum instead of 150-200 ml. The effect of sheep colostrum replacer or cow colostrum was also examined. Gamma globulin titres were significantly high with goat colostrum than with cow colostrum or sheep colostrum replacer, and titres were higher with cow colostrum than with sheep colostrum replacer. Based on the results of this experiment, the following protocol is suggested for colostrum administration to goat kids: single administration of 150-200 ml of goat colostrum within 90 minutes of birth. Use of cow colostrum is not advised because it may lead to transmission of paratuberculosis. Use of sheep colostrum replacer as a source of passive immunity is not recommended.

    To evaluate the effects of storage conditions on total protein (TP) and globulin fractions in fresh frozen bovine plasma units prepared and stored for transfusion, TP and globulin fractions were evaluated in fresh plasma and at 1 month and 6 and 12 months after blood collection in plasma stored at -20°C. Significant differences in concentrations were found in the median concentration of total protein (P=0.0336), between 0 months and 1 month (P=0.0108), 0 and 6 months (P=0.0023), and 0 and 12 months (P=0.0027), in mean concentration (g/dL) of albumin (P=0.0394), between 0 months and 1 month (P=0.0131), 0 and 6 months (P=0.0035), and 0 and 12 months (P=0.0038), and beta-2 fraction (P=0.0401), between 0 and 6 months (P=0.0401) and 0 and 12 months (P=0.0230). This study suggests that total gamma globulin concentration in bovine frozen plasma is stable for 12 months at -20°C. Total protein, ALB, and beta-2 fraction have significantly different concentrations (g/dL) when compared to prestorage. This study has shown IgG protein fraction stability in bovine fresh frozen plasma collected for transfusion; therefore, bovine fresh frozen plasma seems to be suitable for the treatment of hypogammaglobulinemia (failure of passive transfer) in calves when stored for 12 months at -20°C.

    Two patients developed anaphylaxis after injection of a corticosteroid preparation containing carboxymethylcellulose (E466). In both cases skin tests yielded positive immediate type reactions to pure carboxymethylcellulose. This hydrophilic derivative of cellulose has found wide application in the pharmaceutical, cosmetics and food industry. The diagnosis is based on skin testing as 9% of the normal population was found to have serum IgE antibodies to this compound. In case of anaphylaxis after injection of corticosteroids, carboxymethylcellulose in addition to corticosteroids should be included for skin testing.

    In this study the surface composition of 7S and 11S globulin powders from soybean proteins by aqueous buffer and reverse micelle extractions had been examined using X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Analysis by XPS revealed that the O and N atomic percentage of 7S and 11S globulin surfaces from bis(2-ethylhexyl) sodium sulfosuccinate (AOT) reverse micelle was higher than from aqueous buffer, but the C atomic percentage was lower. The O/C ratio of the 7S globulin powder from aqueous buffer and reverse micelle was similar while significant differences were obtained in the O/C ratio of the 11S globulin powder, N/C atom ratios of the 7S and 11S globulin powders and high-resolution XPS C 1s, N 1s, O 1s spectra. Powder microstructure after reverse micelle treatment showed the presence of small pores, indicating the effect of reverse micelle on the 7S and 11S globulin structure. The obtained results indicated that the reverse micelle could affect the C, O and N components on the surface of soybean proteins. Copyright © 2011 Elsevier B.V. All rights reserved.

    Purpose To evaluate the benefits and complications of periocular depot corticosteroid injections in patients with ocular inflammatory disorders. Design Multicenter retrospective cohort study. Participants A total of 914 patients (1192 eyes) who had received at least one periocular corticosteroid injection at 5 tertiary uveitis clinics in the United States. Methods Patients were identified from the Systemic Immunosuppressive Therapy for Eye Diseases (SITE) Cohort Study. Demographic and clinical characteristics were obtained at every visit via medical record review by trained reviewers. Main Outcome Measures Control of inflammation, improvement of visual acuity to 20/40 or better, improvement of visual acuity loss attributed to macular edema, incident cataract affecting visual acuity, cataract surgery, ocular hypertension and glaucoma surgery. Results Among 914 patients (1192 eyes) who received at least one periocular injection during follow-up, 286 (31.3%) were classified as having anterior uveitis, 303 (33.3%) as intermediate uveitis, 324 (35.4%) as posterior or panuveitis. Cumulatively by ≤6 months, 72.7% [95% confidence interval (95%CI): 69.1-76.3] of the eyes achieved complete control of inflammation and 49.7% [95%CI:45.5-54.1] showed an improvement in visual acuity (VA) from worse than 20/40 to 20/40 or better. Among the subset with VA worse than 20/40 attributed to macular edema, 33.1% [95%CI: 25.2-42.7] improved to 20/40 or better. By 12 months, the cumulative incidence of one or more visits with an intraocular pressure≥24 mmHg and ≥30 mmHg was 34.0% [95%CI: 24.8-45.4] and 15.0% [95%CI: 11.8-19.1] respectively; glaucoma surgery was performed in 2.4% [95%CI: 1.4-3.9] of eyes. Within 12 months, among phakic eyes initially 20/40 or better, the incidence of a reduction in VA to worse than 20/40 attributed to cataract was 20.2% [95%CI: 15.9-25.6]; cataract surgery was performed within 12 months in 13.8 % [95%CI: 11.1-17.2] of the initially phakic eyes

MethodsA total of 46 previously untreated CHC patients who were admitted to Tangdu Hospital, Fourth Military Medical University, from October 2015 to May 2016 were enrolled, and 32 healthy laboratory technicians and persons who underwent physical examination in our hospital were enrolled as healthy control group. Flow cytometry was used to measure the percentage of Tfh cells in CD4+ T cells and the change in its subset (CD4+CXCR5+PD-1+ T cells in peripheral blood, an automatic biochemical analyzer was used to measure the serum globulin level, and real-time PCR was used to measure the mRNA expression of Ascl2 in Tfh cells. The association between the changes in these parameters and HCV infection was analyzed. The independent samples t-test was used for the comparison of continuous data between groups, and the Pearson correlation analysis was also performed. ResultsIn CHC patients, peripheral Tfh cells were positively correlated with B lymphocytes (r=0.582 3, P=0.011 2, peripheral B lymphocytes were positively correlated with globulin (r=0.450 9, P=0.031 6, and Tfh cells were positively correlated with globulin (r=0.583 5, P=0.038 3. CHC patients had significantly higher mRNA expression of Ascl2 in peripheral Tfh cells than the healthy control group (1.019±0.666 vs 6.437±5.776, t=4.552, P=0.001 9. ConclusionTfh cells may be involved in the production of serum globulin in CHC patients, and the transcription factor Ascl2 may participate in the differentiation and development of Tfh cells in the process of HCV infection.

    Full Text Available Introduction: Topical corticosteroids (TCS have been widely used in various dermatological diseases. However, because of inadvertent use, TCS misuse has become a common problem faced by dermatologists in various parts of the world. Prolonged use over the face can cause various side effects such as steroid rosacea, acneiform eruptions, and hypertrichosis. Aim: To study the effects of TCS misuse and analyze various factors promoting its use on face. Materials and Methods: A total of 100 patients presenting with various facial dermatoses following the misuse of TCS on the face were studied. Detailed history was noted and the various side effects were recorded. Results: Majority of the patients (70% were females with maximum number of patients belonging to the age group of 11–20 years. Eighty-five percent of the patients were applying TCS for medical conditions, with acne being the most common indication, and the rest were applying as a general face cream. Pruritus and acneiform eruptions were the most common side effects observed and the other reported were erythema, photosensitivity, steroid dependent face, and telangiectasia. Conclusion: TCS misuse especially over the face can lead to a multitude of side effects. It is high time to create awareness among the patients as well as doctors regarding the proper usage of this wonder drug.

    Full Text Available BACKGROUND Plantar fasciitis is the most common cause of heel pain for which professional care is sought. Initially thought of as an inflammatory process, plantar fasciitis is a disorder of degenerative changes in the fascia and maybe more accurately termed plantar fasciosis. Traditional therapeutic efforts have been directed at decreasing the presumed inflammation. These treatments include icing, Nonsteroidal Anti-inflammatory Drugs (NSAIDs, rest and activity modification, corticosteroids, botulinum toxin type A, splinting, shoe modifications and orthosis. Other treatment techniques have been directed at resolving the degeneration caused by the disease process. In general, these techniques are designed to create an acute inflammatory reaction with the goal of restarting the healing process. These techniques include autologous blood injection, Platelet-Rich Plasma (PRP injection, nitroglycerin patches, Extracorporeal Shock Wave Therapy (ESWT and surgical procedures. Recently, research has focused on regenerative therapies with high expectations of success. The use of autologous growth factors is thought to heal through collagen regeneration and the stimulation of a well-ordered angiogenesis. These growth factors are administered in the form of autologous whole blood or Platelet-Rich Plasma (PRP. Platelets can be isolated using simple cell-separating systems. The degranulation of the alpha granules in the platelets releases many different growth factors that play a role in tissue regeneration processes. Platelet-derived growth factor, transforming growth factor-P, vascular-derived endothelial growth factor, epithelial growth factor, hepatocyte growth factor and insulin-like growth factor are examples of such growth factors. Injections with autologous growth factors are becoming common in clinical practice. The present study was an attempt to compare the efficacy of autologous blood injection in plantar fasciitis by comparing it with the local

    Full Text Available Objective: To compare the efficacy of up to 3 epidural butorphanol plus corticosteroid with corticosteroid alone for sciatica due to herniated nucleus pulposus. Materials and Methods: In a randomized, double-blind controlled clinical trial, we administered up to 3 epidural injections of either 80 mg (2 mL of methylprednisolone acetate and 1 mg (1 mL of butorphanol diluted with 7 mL of isotonic saline or 80 mg (2 mL of methylprednisolone acetate diluted with 8 mL of isotonic saline by a lumbar interlaminar approach under fluoroscopic guidance to 120 patients (60 patients in each group with sciatica due to a herniated nucleus pulposus lasting for 4 weeks to 1 year. All patients had scores higher than 30 mm on visual analog scale (VAS. Information on the use of paracetamol, intensity of pain on a VAS ranging from 0 (no pain to 100 mm (worst pain possible, Schober′s test (cm, Straight Leg Raising test, neurologic examination assessing sensory deficits, motor deficits and reflex changes, and Oswestry Low Back Pain Disability Questionnaire were evaluated at 3 weeks, 6 weeks, and 3 months after the first injection. Results: There were no significant differences between the 2 groups with regard to baseline characteristics, withdrawals, and complication rate. Three weeks, 6 weeks, and 3 months after the first injection, all the outcome measures in the butorphanol plus corticosteroid group were significantly different from that of the corticosteroid group. Conclusions: Epidural butorphanol plus corticosteroid injections, as compared with corticosteroid alone injections, offered marked improvement in pain, reflex, motor and sensory deficits, and functional status and reduced the need for analgesics. Level of Evidence: Therapeutic Level I.

    1996-01-13

    In four patients, men of 64, 66 and 69 years old and a woman of 65 years, who suffered from chronic obstructive pulmonary disease (COPD) and used inhalation corticosteroids in a relatively high dose (800-1600 micrograms of budesonide per day), a pulmonary infection was diagnosed caused by Mycobacterium malmoense (the first two patients) and Aspergillus (the other two) respectively. Inhalation corticosteroids are of great importance in the treatment of asthmatic patients. Their place in the treatment of patients with COPD is much less clear. The patients did not have an immunological deficiency or anatomical pulmonary or bronchial deformation which could have explained the occurrence of these infections. The high dosages of inhalation corticosteroids may have been involved in the cause of these infections by suppressing the T-cell response locally. In view of this, longterm inhalation corticosteroid treatment should be prescribed in COPD patients only if the efficacy of the medication has been proved in the individual patient involved.

  17. Investigation of sensitivity of the hypothalamus to corticosteroids at late postradiation stages

    Energy Technology Data Exchange (ETDEWEB)

    Prokudina, E.A.

    1979-03-01

    Corticosteroid receptors have been found in neurons of the hypothalamus, hippocampus, septum and amygdaloid nucleus. Analysis of the effects of corticosteroids on receptor structures of the hypothalamoreticulolimbic complex revealed complex correlations between them and possibility of concurrent effects of corticosteroids on adrenergic, serotoninergic and cholinergic systems. Expressly in these systems of the hypothalamus some substantial disturbances were found at late postradiation stages. In view of the fact that the mechanism of negative feedback is implemented in the centers of regulation of the adrenohypophyseal system, examination of the reaction of this system to corticosteroids could serve as one of the indicators of the state of its centers. We applied this principle to our study of the functional state of the hypothalamus at the long postradiation term.

    Anorexia is a significant problem in patients approaching the end of life, for which corticosteroids are widely prescribed. It is not clear which regimen is the most safe and effective for this indication. The study objective was to identify the evidence for the use of corticosteroids, and the most safe and effective dosing regimen for management of anorexia in palliative care patients. A search of MEDLINE and CINAHL was carried out to identify original studies relevant to this question. These were reviewed against inclusion criteria and articles for inclusion were identified. Data was extracted and a narrative analysis was carried out. Subjects were adult patients with life-limiting diagnoses prescribed corticosteroids for anorexia in any care setting. Quality of studies was assessed using the system used by the Scottish Intercollegiate Guidelines Network for grading evidence. Eight articles were identified that met the inclusion criteria. The corticosteroid drugs and dosing regimens used were wide ranging, and a variety of tools were used to assess appetite within these studies. All studies showed improvement in appetite with the corticosteroid used, although this did not always reach statistical significance. It was not possible to identify the most effective corticosteroid drug, dose, or duration of treatment from the identified studies: the best quality evidence was for an eight-week course of intravenous methylprednisolone; however the studies using this regimen had the highest attrition rates. Corticosteroids are beneficial in treating anorexia in palliative care patients with malignancies; however there is no evidence for their use in anorexia due to end-stage nonmalignant disease. There is insufficient evidence to recommend any particular corticosteroid drug over another, or to recommend a dosing regimen.

  1. Gene expression changes associated with resistance to intravenous corticosteroid therapy in children with severe ulcerative colitis.

    Directory of Open Access Journals (Sweden)

    Boyko Kabakchiev

    Full Text Available BACKGROUND AND AIMS: Microarray analysis of RNA expression allows gross examination of pathways operative in inflammation. We aimed to determine whether genes expressed in whole blood early following initiation of intravenous corticosteroid treatment can be associated with response. METHODS: From a prospectively accrued cohort of 128 pediatric patients hospitalized for intravenous corticosteroid treatment of severe UC, we selected for analysis 20 corticosteroid responsive (hospital discharge or PUCAI ≤45 by day 5 and 20 corticosteroid resistant patients (need for second line medical therapy or colectomy, or PUCAI >45 by day 5. Total RNA was extracted from blood samples collected on day 3 of intravenous corticosteroid therapy. The eluted transcriptomes were quantified on Affymetrix Human Gene 1.0 ST arrays. The data was analysed by the local-pooled error method for discovery of differential gene expression and false discovery rate correction was applied to adjust for multiple comparisons. RESULTS: A total of 41 genes differentially expressed between responders and non-responders were detected with statistical significance. Two of these genes, CEACAM1 and MMP8, possibly inhibited by methylprednisolone through IL8, were both found to be over-expressed in non-responsive patients. ABCC4 (MRP4 as a member of the multi-drug resistance superfamily was a novel candidate gene for corticosteroid resistance. The expression pattern of a cluster of 10 genes selected from the 41 significant hits were able to classify the patients with 80% sensitivity and 80% specificity. CONCLUSIONS: Elevated expression of several genes involved in inflammatory pathways was associated with resistance to intravenous corticosteroid therapy early in the course of treatment. Gene expression profiles may be useful to classify resistance to intravenous corticosteroids in children with severe UC and assist with clinical management decisions.

    Plantar fasciitis is a common cause of heel pain. It is a disabling disease in its chronic form. It is a degenerative tissue condition of the plantar fascia rather than an inflammation. Various treatment options are available, including nonsteroidal anti-inflammatory drugs, corticosteroid injections, orthosis, and physiotherapy. This study compared the effects of local platelet-rich plasma, corticosteroid, and placebo injections in the treatment of chronic plantar fasciitis. In this double-blind study, patients were divided randomly into 3 groups. Local injections of platelet-rich plasma, corticosteroid, or normal saline were given. Patients were assessed with the visual analog scale for pain and with the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hindfoot score before injection, at 3 weeks, and at 3-month follow-up. Mean visual analog scale score in the platelet-rich plasma and corticosteroid groups decreased from 7.44 and 7.72 preinjection to 2.52 and 3.64 at final follow-up, respectively. Mean AOFAS score in the platelet-rich plasma and corticosteroid groups improved from 51.56 and 55.72 preinjection to 88.24 and 81.32 at final follow-up, respectively. There was a significant improvement in visual analog scale score and AOFAS score in the platelet-rich plasma and corticosteroid groups at 3 weeks and at 3-month follow-up. There was no significant improvement in visual analog scale score or AOFAS score in the placebo group at any stage of the study. The authors concluded that local injection of platelet-rich plasma or corticosteroid is an effective treatment option for chronic plantar fasciitis. Platelet-rich plasma injection is as effective as or more effective than corticosteroid injection in treating chronic plantar fasciitis.

    Family physicians, internists, and pediatricians are more likely to prescribe combination topical antifungal-topical corticosteroid preparations than are dermatologists. One such preparation, clotrimazole-betamethasone dipropionate, can cause atrophy because it has a high-potency corticosteroid component. We analyzed data from the National Ambulatory Medical Care Survey for visits to pediatricians from 1990 to 1994 and isolated visits at which a topical corticosteroid agent or clotrimazole-betamethasone dipropionate was prescribed. Pediatricians rarely prescribed single-agent, high-potency topical corticosteroid agents in managing patients with skin disorders. High-potency corticosteroid agents accounted for 5.0% of topical corticosteroid prescriptions, whereas 56.3% were low-potency and 38.7% were medium-potency agents. Of the 696,285 mentions of clotrimazole-betamethasone dipropionate, 56.4% (389,920) were for children aged newborn to 4 years; diagnoses were erythematodesquamatous dermatoses, diaper rash, tinea, well-baby visit, and candidiasis. In contrast, for dermatologists nationwide, no drug mention existed for this combination agent for children aged newborn to 4 years over the 5-year study period. Our results show that clotrimazole-betamethasone dipropionate is prescribed inappropriately by pediatricians, especially in the treatment of young children. Pediatricians rarely use high-potency topical corticosteroid agents, but most of their use of clotrimazole-betamethasone dipropionate is in the youngest children, in whom such corticosteroid use is least appropriate. This prescription pattern suggests that some pediatricians may be unaware that clotrimazole-betamethasone dipropionate has a high-potency cortico steroid component.

  6. Corticosteroids or non-corticosteroids:a fresh perspective on alcoholic hepatitis treatment

    2011-01-01

    BACKGROUND: Alcoholic hepatitis (AH) is a necrotizing inflammatory process caused by alcoholic liver injury. It carries a significant short-term mortality. The management of AH is challenging. Although corticosteroids have been demonstrated to exert anti-inflammatory and antifibrotic effects, their efficacy for the treatment of AH remains debatable. DATA  SOURCES: A literature search was performed of MEDLINE, ScienceDirect, SpringerLink and Wiley InterScience usingthekey words"alcoholichepatitis","alcoholicliverdisease", and "corticosteroids". The available data reported in the relevant literaturewereanalyzed. RESULTS: More than 17 controlled trials and at least 13 meta-analyses have reported the efficacy of corticosteroids in the treatment of AH in the past 40 years. Many were poorly designed and used different inclusion/exclusion criteria, making it difficult to reach a consensus. In this review, we summarized all the controversial data in the past decade and analyzed the potential causes for the varying therapeutic effects of corticosteroids in AH. The focus of the controversy has changed from "whether steroids are beneficial or harmful for AH patients" to "how to accurately identify responders to steroids early and rationalize corticosteroid treatment". An early response to glucocorticoids, as determined by calculating the Lille score after 7 days of treatment, has been shown to be a clinically useful indicator. Moreover, down-regulation of steroid sensitivity, risk of infection, and a rational therapeutic strategy of corticosteroids in AH patients are all crucial for therapeutic effect. CONCLUSIONS: An early and accurate determination of steroid sensitivity is important. Besides, we need to overcome the down-regulation of steroid sensitivity, reduce the infection risk and rationalize the therapeutic strategy of corticosteroids. A fresh perspective is needed on the use of corticosteroids in AH patients.

    Vasoconstrictor assay described in 1962 was an interesting assessment of potency of topical corticosteroids at the beginning of these new therapies, however knowledge and technology have evolved and the classification should follow. A topical corticosteroids with a strong vasoconstrictor effect, as determined by vasoconstrictor assay, has not necessary a strong anti-inflammatory effect. Therefore a specific classification adapted to the therapeutic target is needed to be more efficient and thus reduce side effects and corticophobia.

    Corticosteroids are frequently prescribed anti-inflammatory medications. Inhaled corticosteroids (ICS) are indicated for Chronic Obstructive Pulmonary Disease (COPD) and asthma. ICS are associated with a decrease in exacerbations and improved quality of life in COPD, however multiple studies have linked the chronic use of ICSs with an increased risk of developing pneumonia, though the effect on mortality is unclear. We review the association of ICS with the risk of pneumonia and the implications on clinical outcomes.

    AIM:To establish a simple model consisting of the routine laboratory variables to predict both minimal fibrosis and cirrhosis in chronic hepatitis B virus (HBV)-infected patients.METHODS:We retrospectively investigated 114 chronic HBV-infected patients who underwent liver biopsy in two different hospitals.Thirteen parameters were analyzed by step-wise regression analysis and correlation analysis.A new fibrosis index [globulin/platelet (GP) model] was developed,including globulin (GLOB) and platelet count (PLT).GP model =GLOB (g/mL) x 100/PLT (x 109/L).We evaluated the receiver operating characteristics analysis used to predict minimal fibrosis and compared six other available models.RESULTS:Thirteen clinical biochemical and hematological variables [sex,age,PLT,alanine aminotransferase,aspartate aminotransferase (AST),albumin,GLOB,total bilirubin (T.bil),direct bilirubin (D.bil),glutamyl transferase,alkaline phosphatase,HBV DNA and prothrombin time (PT)] were analyzed according to three stages of liver fibrosis (F0-F1,F2-F3 and F4).Bivariate Spearman's rank correlation analysis showed that six variables,including age,PLT,T.bil,D.bil,GLOB and PT,were correlated with the three fibrosis stages (FS).Correlation coefficients were 0.23,-0.412,0.208,0.220,0.314 and 0.212; and P value was 0.014,< 0.001,0.026,0.018,0.001 and 0.024,respectively.Univariate analysis revealed that only PLT and GLOB were significantly different in the three FS (PLT:F =11.772,P <0.001; GLOB:F =6.612,P =0.002).Step-wise multiple regression analysis showed that PLT and GLOB were also independently correlated with FS (R2 =0.237).By Spearman's rank correlation analysis,GP model was significantly correlated with the three FS (r =0.466,P < 0.001).The median values in F0-F1,F2-F3 and F4 were 1.461,1.720 and 2.634.Compared with the six available models (fibrosis index,AST-platelet ratio,FIB-4,fibrosis-cirrhosis index and age-AST model and age-PLT ratio),GP model showed a highest correlation

  10. What the world's religions teach, applied to vaccines and immune globulins.

    For millennia, humans have sought and found purpose, solace, values, understanding, and fellowship in religious practices. Buddhist nuns performed variolation against smallpox over 1000 years ago. Since Jenner developed vaccination against smallpox in 1796, some people have objected to and declined vaccination, citing various religious reasons. This paper reviews the scriptural, canonical basis for such interpretations, as well as passages that support immunization. Populous faith traditions are considered, including Hinduism, Buddhism, Jainism, Judaism, Christianity, and Islam. Subjects of concern such as blood components, pharmaceutical excipients of porcine or bovine origin, rubella strain RA 27/3, and cell-culture media with remote fetal origins are evaluated against the religious concerns identified. The review identified more than 60 reports or evaluations of vaccine-preventable infectious-disease outbreaks that occurred within religious communities or that spread from them to broader communities. In multiple cases, ostensibly religious reasons to decline immunization actually reflected concerns about vaccine safety or personal beliefs among a social network of people organized around a faith community, rather than theologically based objections per se. Themes favoring vaccine acceptance included transformation of vaccine excipients from their starting material, extensive dilution of components of concern, the medicinal purpose of immunization (in contrast to diet), and lack of alternatives. Other important features included imperatives to preserve health and duty to community (e.g., parent to child, among neighbors). Concern that 'the body is a temple not to be defiled' is contrasted with other teaching and quality-control requirements in manufacturing vaccines and immune globulins. Health professionals who counsel hesitant patients or parents can ask about the basis for concern and how the individual applies religious understanding to decision-making about

    Full Text Available Abstract Background Intravenous gamma globulin (IVGG is commonly used in the management of acute myocarditis. The objective of this study was to systematically review the literature evaluating this practice. Methods We conducted a comprehensive search (electronic databases, trials registries, conference proceedings, reference lists, contact with authors to identify studies evaluating the use of IVGG in adults and children with a clinical or histologically proven diagnosis of myocarditis of possible viral etiology and symptoms of less than six months duration. Two reviewers independently screened the searches, applied inclusion criteria, and graded the evidence. Results Results were described qualitatively; data were not pooled because only one randomized controlled trial (RCT with 62 patients was identified. The RCT showed no benefit with respect to cardiac function, functional outcome, or event-free survival. A small, uncontrolled trial (n = 10 showed significant improvement in LVEF from a mean of 24% to 41% 12 months after IVGG in nine survivors. A retrospective cohort study of pediatric patients showed improvement in cardiac function and a trend towards improved survival in patients receiving IVGG (n = 21 versus historic controls (n = 25. Ten case reports and two case series (total n = 21 described improvement in cardiac function after administration of IVGG; two case reports showed no benefit of IVGG. One case of hemolytic anemia was attributed to IVGG. Conclusion There is insufficient data from methodologically strong studies to recommend routine use of IVGG for acute myocarditis. Future randomized studies that take into account the etiology of acute myocarditis will be required to determine the efficacy of IVGG.

  12. Intravenous immune globulin in hereditary inclusion body myopathy: a pilot study

    Dorward Heidi

    2007-01-01

    Full Text Available Abstract Background Hereditary Inclusion Body Myopathy (HIBM is an autosomal recessive, adult onset, non-inflammatory neuromuscular disorder with no effective treatment. The causative gene, GNE, codes for UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase, which catalyzes the first two reactions in the synthesis of sialic acid. Reduced sialylation of muscle glycoproteins, such as α-dystroglycan and neural cell adhesion molecule (NCAM, has been reported in HIBM. Methods We treated 4 HIBM patients with intravenous immune globulin (IVIG, in order to provide sialic acid, because IgG contains 8 μmol of sialic acid/g. IVIG was infused as a loading dose of 1 g/kg on two consecutive days followed by 3 doses of 400 mg/kg at weekly intervals. Results For all four patients, mean quadriceps strength improved from 19.0 kg at baseline to 23.2 kg (+22% directly after IVIG loading to 25.6 kg (+35% at the end of the study. Mean shoulder strength improved from 4.1 kg at baseline to 5.9 kg (+44% directly after IVIG loading to 6.0 kg (+46% at the end of the study. The composite improvement for 8 other muscle groups was 5% after the initial loading and 19% by the end of the study. Esophageal motility and lingual strength improved in the patients with abnormal barium swallows. Objective measures of functional improvement gave variable results, but the patients experienced improvements in daily activities that they considered clinically significant. Immunohistochemical staining and immunoblotting of muscle biopsies for α-dystroglycan and NCAM did not provide consistent evidence for increased sialylation after IVIG treatment. Side effects were limited to transient headaches and vomiting. Conclusion The mild benefits in muscle strength experienced by HIBM patients after IVIG treatment may be related to the provision of sialic acid supplied by IVIG. Other sources of sialic acid are being explored as treatment options for HIBM.

    Horse antithymocyte globulin (h-ATG) (ATGAM(®) ) is the first choice of treatment in very severe patients with aplastic anemia who do not have any HLA matched sibling donor. h-ATG is a heterologous serum that may cause anaphylaxis. Alternative treatment strategies must be planned in case of hypersensitivity. Desensitization must be considered in patients without an alternative treatment of choice. We aimed to present the h-ATG desensitization protocol and consider its effectiveness in patients with aplastic anemia who are hypersensitized with h-ATG and do not have an alternative treatment of choice. Skin prick tests were performed with non-diluted solution in eight very severe patients with aplastic anemia who are followed up in Ege University Children's Hospital. Although skin prick test was found negative in these eight patients, different dilution h-ATG intradermal tests were performed and found positive in all patients. h-ATG desensitization program was started to these hypersensitized patients. Desensitization program was started to six male and two female very severe patients with aplastic anemia whose ages were between seven and 19 yr (median: 12.9 yr). All of the patients completed the desensitization program. While local reaction was seen in two patients, systemic reaction was seen in one patient and late reaction was seen in one patient during and after desensitization program. A successful desensitization program with h-ATG in children with aplastic anemia is presented. Even though there is not an exposure before to such high allergy potential heterologous serum, skin tests should be performed and desensitization must be started to patients who are hypersensitized to h-ATG. As the expected effectiveness of the treatment is so much, the desensitization protocol can be carried out safely and effectively with trained stuff although allergic reactions can be seen. © 2015 John Wiley & Sons A/S.

    Though causes of autism are considered largely genetic, considerable concern remains that exposure to Rh immune globulin (RhIg), which until 2001 in the United States contained the preservative thimerosal, can cause autism. To determine whether mothers of children with autism are more likely to be Rh negative (Rh(-)) or to have received RhIg preserved with thimerosal, which is 49.6% ethyl mercury, we surveyed families of children with an autism spectrum disorder (ASD) ascertained through a University-based autism clinic considered free of ascertainment biases related to type of autism or severity. Between 2004 and 2006, 305 mothers of 321 children with an ASD agreed to participate in a telephone interview. Analysis of complete records including the blood group status and RhIg exposure of 214 families showed that Rh(-) status is no higher in mothers of children with autism than in the general population, exposure to antepartum RhIg, preserved with thimerosal is no higher for children with autism and pregnancies are no more likely to be Rh incompatible. This was also true for autism subgroups defined by behavioral phenotype, gender, IQ, regressive onset, head circumference, dysmorphology, birth status, essential, or complex phenotype. These findings support the consensus that exposure to ethylmercury in thimerosal is not the cause of the increased prevalence of autism. These data are important not only for parents in this country but also for the international health community where thimerosal continues to be used to preserve multi-dose vials which in turn makes vaccines affordable.

  15. Rh(O)D immune globulin products for prevention of alloimmunization during pregnancy.

    The pharmacologic properties of Rhesus (Rh) immune globulin (RhIG) and clinical data on its effectiveness in preventing Rh-antigen alloimmunization in pregnant women are reviewed. RhIG is a human plasma derivative that targets red blood cells (RBCs) positive for Rh(O) antigen (also called D antigen). In the United States and other countries, the widespread use of RhIG has markedly reduced the occurrence of hemolytic disease of the fetus and newborn (HDFN), a devastating condition caused by D-antigen sensitization of a pregnant woman via exposure to fetal RBCs (usually during detachment of the placenta in labor) that results in a maternal immune response leading to severe hemolysis in the fetus. Routine administration of RhIG at 26-30 weeks' gestation and again within 72 hours of delivery has been shown to be highly effective in preventing maternal Rh alloimmunization, with very low rates of D-antigen sensitization (in the range of 0-2.2%) reported in multiple studies of at-risk women. The four RhIG products currently available in the United States have common clinical indications but differ in certain attributes. Pharmacists can play an important role in guiding other clinicians on the rationale for the use of RhIG, important differences between products, and appropriate timing of RhIG therapy. Routine administration of RhIG to women at risk for Rh alloimmunization is clinically effective and has made HDFN a rare clinical event. The available RhIG products are not the same and should be carefully reviewed to ensure that they are administered safely. Copyright © 2015 by the American Society of Health-System Pharmacists, Inc.

    Full Text Available We conducted a single-center prospective double-arm open-labeled study on kidney transplant patients from 2010 to 2011 to evaluate the efficacy of induction therapy using low, single-dose rabbit-antithymocyte globulin (r-ATG, 1.5 mg/kg on Day 0 (n = 80, 60 males, mean age 35.9 years, versus basiliximab (Interleukin-2 blocker 20 mg on Days 0 and 4 (n = 20, 12 males, mean age 45.1 years on renal allograft function in terms of serum creatinine (SCr, rejec-tion and infection episodes and patient/graft survival and cost. Demographic and post-transplant follow-up including immunosuppression was similar in both groups. In the r-ATG group, donors were unrelated (spouse, n = 25, deceased (n = 31 and parents/siblings (others, with a mean HLA match of 1.58. Donors in the basiliximab group were living unrelated (spouse, n = 15 and deceased (n = 5, with a mean HLA match of 1.56. No patient/graft was lost in the r-ATG group over a mean of one year follow-up, and the mean SCr was 1.28 mg/dL with 7.5% acute rejection (AR episodes; infections were also not observed. In the basiliximab group, over the same period of follow-up, there was 95% death-censored graft survival, and the mean SCr was 1.23 mg/dL with 10% AR episodes. One patient died due to bacterial pneumonia and one succumbed to coronary artery disease; one graft was lost due to uncontrolled acute humoral and cellular rejection. The cost of r-ATG and basiliximab were $600 and $2500, respectively. We conclude that induction immunosuppressive therapy with a low-dose r-ATG may be a better option as compared with basiliximab in terms of graft function, survival and cost benefit in kidney transplant patients.

    Full Text Available Objective. To evaluate the beneficial effects and safety of corticosteroids combined with traditional Chinese medicine (TCM for pemphigus. Methods. Seven electronic databases were searched to identify any potential randomized controlled trials (RCTs or clinical controlled trials (CCTs that compared corticosteroids with and without TCM for the treatment of pemphigus, published in any language. Remission of the mucocutaneous lesions, therapeutic duration, dosage of corticosteroids, and specific antibody titers were employed as the main outcome measures. The methodological quality of the included studies was assessed using the Cochrane Handbook for Systematic Review of Interventions and Rev Man 5.1.0 software. Results. Four RCTs with a total of 199 patients were included in the present review. Management with corticosteroids combined with TCM seemed to benefit pemphigus patients in terms of healing of lesions, prevention of complications and relapse, and reduced interferon-gamma (IFN-γ level. The trials were not of high methodological quality. No study mentioned allocation concealment and blinding. Only one trial reported adverse events, and it indicated that the safety of corticosteroids combined with TCM was uncertain. Conclusion. There is some, albeit weak, evidence to show that combined treatment with corticosteroids with TCM could be of benefit for some patients with pemphigus. The efficacy and safety of this combined treatment should be evaluated further in better designed, fully powered, and confirmatory RCTs.

    Women at risk for preterm delivery are treated with synthetic glucocorticoids (GCs) to enhance fetal lung maturation. GCs can bind to two intracellular receptors, the glucocorticoid receptor (GR) and the mineralocorticoid receptor (MR), which function as transcription factors. Both are highly expressed in the hippocampus. Several studies have focused on adverse side effects of antenatal GC treatment. However, relatively little is known about the ontogeny of GR and MR, especially in human. Therefore, we studied the ontogeny of both receptors in the human and mouse hippocampus and investigated the effects of antenatal dexamethasone (dex) treatment, a synthetic glucocorticoid, on MR and GR mRNA levels during hippocampal development. The results demonstrate that MR mRNA was first expressed in mouse hippocampus at embryonic day (E)15.5, at the timepoint when dex was administered. In contrast, GR mRNA expression was first observed after birth at postnatal day (P)5. However, in the human hippocampus both receptors are expressed at 24 weeks of gestation, when antenatal GCs are administered in clinical practice. Quantitative in situ hybridization demonstrated that MR mRNA levels were reduced only shortly after dex treatment at E16, but were unaffected from E18 onwards. These findings indicate that a single antenatal dex administration at E15.5 transiently affects MR mRNA levels in the mouse hippocampus. No effect of antenatal dex treatment was found on the human hippocampus at the third trimester of pregnancy. These data on the prenatal ontogeny of both corticosteroid receptors in the human hippocampus is important for understanding the significance of fetal glucocorticoid or stress exposure and its potential effects on health and disease.

    The effects of high-dose corticosteroids (HDC) on activities within the proteolytic cascade systems were studied in vitro and in vivo using chromogenic peptide substrate assays. In in vitro experiments 20 mg methylprednisolone sodium succinate (Solu-Medrol) per ml plasma significantly inhibited activation of plasma prekallikrein, prothrombin and plasminogen and reduced functional plasma kallikrein inhibition, antithrombin and antiplasmin activities. The effects of HDC on activities within these proteolytic cascade systems were further evaluated in experimental acute pancreatitis in pigs. Acute pancreatitis was induced by injection of Na-taurocholate into the pancreatic duct. Seven test animals received methylprednisolone sodium succinate 30 mg per kg intravenously for 30 minutes before the induction of pancreatitis as pretreatment. Eight animals remained untreated. Trypsin (TRY), plasma prekallikrein (PKK), plasma kallikrein (KK) and functional plasma kallikrein inhibition capacity (KKI) were studied in the peritoneal exudate. Cardiac output (CO) and mean arterial pressure (MAP) were monitored regularly before and during a 6 hour observation period. During untreated pancreatitis a reduction of PKK levels of about 40% were found, paralleled by an increased KK activity and a reduction of KKI capacity. Several of the animals experienced high TRY activities. The mortality rate was 63% (5 out of 8 animals). In the pretreated groups, all animals survived the observation period. CO and MAP were significantly less reduced than the untreated group at 6 hours. HDC was also found to reduce significantly plasma kallikrein activities in the peritoneal exudate compared with untreated animals. No changes in TRY activities were found in pretreated animals. Furthermore, plasma prekallikrein and functional plasma kallikrein inhibition values in the exudate were elevated significantly in HDC treated animals compared with untreated animals.

  1. The role of corticosteroids and stress in chronic pain conditions.

    2010-10-01

    The relationship between corticosteroids (endogenous and exogenous) and stress is well known, as is the use of steroids as concomitant treatment in pain management during acute inflammation. In the past, steroids have not been considered the first line of treatment in pain management. In this review, we examine new scientific and clinical evidence that demonstrates the direct role that steroids play in the generation and clinical management of chronic pain. We will discuss the new findings demonstrating the fact that steroids and related mediators produce paradoxical effects on pain such as analgesia, hyperalgesia, and even placebo analgesia. In addition, we will examine the physiologic effect of stress, high allostatic load, and idiopathic disease states such as chronic fatigue syndrome, fibromyalgia, irritable bowel syndrome, and burnout. The recently observed positive relationship between glutaminergic activity in the insula and clinical pain will be examined in the context of understanding the central role of steroids in chronic pain. The complex role of the hypothalamic-pituitary-adrenal axis in pain will be discussed as well as other heterogeneous forms of chronic pain that involve many components of the central nervous system. Components of the hypothalamic-pituitary-adrenal axis have paradoxical effects on certain types of pain that are dependent on dose and on site (whether peripheral or central) and mode of application. Recent studies on glia have shown that they prolong a state of neuronal hypersensitization in the dorsal root ganglia by releasing growth factors and other substances that act on the immune system. We will discuss the implication of these new findings directly linking pain to steroids, stress, and key higher brain regions in the context of future therapeutic targets.

  2. Transgenic rabbits that overexpress the neonatal Fc receptor (FcRn generate higher quantities and improved qualities of anti-thymocyte globulin (ATG.

    Full Text Available Immune suppression with rabbit anti-thymocyte globulin (rATG is a well-established therapeutic concept for preventing host rejection of transplanted organs and graft versus host disease. Increasing the efficiency of rATG production by reducing the number of animals would be highly beneficial to lower cost and to improve quality standards. We have developed transgenic (Tg mice and rabbits that overexpress the neonatal Fc receptor (FcRn and have shown an augmented humoral immune response in these animals. To test whether our FcRn Tg rabbits produced rATG more efficiently, we immunized them and their New Zealand White controls with live Jurkat cells. By day 21 after immunization, Tg animals produced significantly, 1.5 times higher amount of total IgG compared to their wt littermates. Also, the binding efficiency of Tg sera to Jurkat cells and their complement-mediated cytotoxicity was significantly higher. The purified Tg IgG preparation contained 2.6 the amount of Jurkat specific IgG as the wt preparation analyzed by complement-mediated lysis, suggesting greater antigen-specific B cell activation in the Tg rabbits. To test this hypothesis, immunization with ovalbumin and human α1-antitrypsin was performed, resulting in significantly greater numbers of antigen-specific B-cells in the FcRn Tg rabbits as compared with wt controls. The shift towards significantly larger populations of antigen-specific B cells relative to the non-specific B cell pool is further corroborated by our previous findings in FcRn Tg mice. Consequently, our FcRn Tg rabbits have the potential to offer substantial qualitative and quantitative improvements for the production of rATG and other polyclonal or monoclonal antibodies.

    Pleural and peritoneal effusion is a common clinical finding in feline practice. Determination of fluid albumin (ALB) and globulin (GLOB) concentrations in addition to total protein (TP) concentration can be helpful in diagnosing or ruling out certain diseases in cats, especially feline infectious peritonitis (FIP). The objective of this study was to compare effusion TP, ALB, and GLOB results obtained by a refractometer and a bench-top dry chemistry analyzer with those results obtained by a reference method. Twenty-six pleural and 14 peritoneal effusion samples were analyzed from 40 cats with various diseases. TP and ALB concentrations were determined by a reference automated wet chemistry analyzer (Kone Specific, Kone Instruments, Espoo, Finland), a bench-top dry chemistry analyzer (Vettest 8008, IDEXX Laboratories Ltd, Chalfont St Peter, UK), and a refractometer (Atago SPR-T2, Atago Co, Tokyo, Japan). GLOB, albumin to globulin (A/G) ratio, and globulins as a percentage of total proteins (GLOB%) were calculated. Results were analyzed by paired t tests, difference plots, and Deming s regression analysis. Correlation coefficients (r) for TP with Vettest versus Kone and refractometer versus Kone methods were.97 and.94, respectively. GLOB and GLOB% values were significantly higher and A/G ratios were significantly lower with Vettest versus Kone methods. Correlation coefficients for ALB, GLOB, GLOB% and A/G ratio with Vettest versus Kone methods were.86,.93,.82, and.73, respectively. Although correlation with other methods was good, the refractometer underestimated TP concentrations in 3 samples. The refractometer is an acceptable method for determination of TP concentration in feline effusions. The Vettest 8008 also is an acceptable method for the determination of TP and ALB concentrations, however, calculated A/G ratios obtained with the Vettest are unacceptable.

    BACKGROUND AND METHODS: In February 1994, batches of anti-D immune globulin used in Ireland during 1977 and 1978 to prevent Rh isoimmunization were found to be contaminated with hepatitis C virus (HCV) from a single infected donor. In March 1994, a national screening program was initiated for all women who had received anti-D immune globulin between 1970 and 1994. Of the 62,667 women who had been screened when this study began, 704 (1.1 percent) had evidence of past or current HCV infection, and 390 of those 704 (55 percent) had positive tests for serum HCV RNA on reverse-transcription-polymerase-chain-reaction analysis. All 390 were offered a referral for clinical assessment and therapy. We evaluated 376 of these 390 women (96 percent); the other 14 were not seen at one of the designated treatment centers. RESULTS: The mean (+\\/-SD) age of the 376 women was 45+\\/-6 years at the time of screening. They had been infected with hepatitis C for about 17 years. A total of 304 women (81 percent) reported symptoms, most commonly fatigue (248 [66 percent]). Serum alanine aminotransferase concentrations were slightly elevated (40 to 99 U per liter) in 176 of 371 women (47 percent), and the concentrations were 100 U per liter or higher in 31 (8 percent). Liver biopsies showed inflammation in 356 of 363 women (98 percent); in most cases the inflammation was slight (41 percent) or moderate (52 percent). Although the biopsy samples from 186 of the 363 women (51 percent) showed evidence of fibrosis, only 7 women (2 percent) had probable or definite cirrhosis. Two of the seven reported excessive alcohol consumption. CONCLUSIONS: Most of the women with HCV infection 17 years after receiving HCV-contaminated anti-D immune globulin had evidence of slight or moderate hepatic inflammation on liver biopsy, about half had fibrosis, and 2 percent had probable or definite cirrhosis.

    To characterize the effects of corticosteroids on choroidal thickness, we measured the choroid thickness in patients treated systemically with a high-dose corticosteroid. A prospective, pilot study was conducted on 20 patients who required high-dose corticosteroid pulse therapy (>500 mg/d). Choroidal thickness was measured at baseline, 1 day, 1 week, and 1 month after corticosteroid administration. Blood pressure was measured four times a day for the first 5 days of steroid treatment. This study ultimately included 35 eyes from 18 patients. Each patient was treated with high-dose corticosteroid therapy at a concentration of 19.5 ± 4.1 mg per kg body weight for 5.2 ± 1.1 days. Mean subfoveal choroidal thickness at baseline was 259.8 μm (range, 86.4-394.7 μm). Choroidal thickness showed no significant change at 1 day, 1 week, or 1 month after corticosteroid administration (P = 0.197). Mean systolic blood pressure increased by 13 mmHg (P = 0.008), but diastolic pressure did not change (P = 0.117). One patient (5.6%) who had presented with pigment epithelial detatchment (PED) and thick choroid (381.1 μm) developed bilateral focal subretinal fluid during the study and showed central serous chorioretinopathy (CSC) with a 13.1% increase in subfoveal choroidal thickness. No consistent changes in choroidal thickness were observed after systemic high-dose corticosteroid treatment, but one patient with PED and thick choroid showed an increase in choroidal thickening as well as features of CSC. Thus, steroid-induced CSC may be an idiosyncratic response in selected vulnerable individuals rather than a dose-dependent effect.

    A number of reports indicating the growing acceptance of simultaneous therapy with multiple disease-modifying anti-rheumatic drugs (DMARDs), as well as the use of more aggressive treatment measures in the early phases of disease to combat rheumatoid arthritis (RA), have appeared during the last decade. However, only a few randomized controlled clinical trials have been conducted on the use of DMARD combinations in early RA. We review these trials in this article. In two separate one-year studies combination therapy with sulphasalazine (SSZ) and methotrexate (MTX) seemed to offer no benefits compared to either drug used as monotherapy. On the other hand, the DMARD combinations so far proven to be superior to single DMARDs have initially also included a corticosteroid component. In the COBRA study (Combinatietherapie Bij Reumatoide Artritis) the combination of SSZ (2 gm/day), MTX (7.5 mg/week for 40 weeks), and prednisolone (Prd) (initially 60 mg/day, tapered in 6 weekly steps to 7.5 mg/day and stopped after 28 weeks) compared to SSZ alone (2 gm/day) resulted in significantly better clinical outcomes at week 28. Although the difference in clinical response between the treatment arms was lost at week 58, the progression of joint damage remained statistically significantly slower at week 80 in the patients initially assigned to the combination therapy. Furthermore, in the FIN-RACo trial (Finnish Rheumatoid Arthritis Combination Therapy Trial), therapy using a "tailored-steps" strategy with SSZ (1-2 gm/day), MTX (7.5-1.5 mg/week), hydroxychloroquine (300 mg/day), and Prd (up to 10 mg/day) yielded a significantly increased remission rate and less peripheral joint damage at two years than the single DMARD treatment strategy (initially SSZ 2 gm/day), with or without Prd. Adverse effects in both study arms were comparable. Two additional preliminary reports (in abstract form) suggest that intensive local therapy in the form of intra-articular injections added to single or

We prospectively investigated the clinical features of patients treated with early adjunctive systemic corticosteroids and its clinical impact in very severe CAP.Methods: One hundred and one consecutive CAP patients having a pneumonia severity index of >130 points were enrolled from August 2010 through February 2013. Early adjunctive systemic corticosteroids were defined as administration of systemic corticosteroids equivalent to prednisone of ≥20 mg/day added to initial antibiotics. The multivariate analysis was performed to evaluate the independent factors associated with mortality.Results: Thirty-two patients (31.7% died within 28 days of admission. Early adjunctive systemic corticosteroids were administered in 30 patients (29.7%, who more frequently had alteration of mental status, serious respiratory failure, or underlying lung diseases and received fluoroquinolones as initial antibiotics. In most patients treated with early adjunctive systemic corticosteroids, the dosage was less than 60 mg/day of an equivalent to prednisone by bolus intravenous infusion for a period shorter than 8 days. The occurrence of adverse events did not differ between the groups. Factors independently associated with mortality were blood urea nitrogen (hazard ratio [HR] 1.02, 95% confidence interval [CI] 1.00–1.04, serum albumin (HR 0.44, 95% CI 0.22–0.86, a requirement for intensive care (HR 4.93, 95% CI 1.75–13.87, and the therapy with early adjunctive systemic corticosteroids (HR 0.29, 95% CI 0.11–0.81.Conclusion: Early adjunctive systemic corticosteroids may have an effect to reduce the mortality in very severe CAP, although a larger-scale study is necessary

    Full Text Available Sclerosing agents (SA are blood inactivated. Nevertheless, investigations concerning the interaction among SA and blood components have never been deeply investigated. Aim of the study is to precisely identify SA blood ligands, to determine their binding time and to highlight the clinical consequences. Thirty-one blood samples were collected from chronic venous disease patients and tested by capillary and agarose gel (AGE electrophoresis before and after adding polidocanol (POL and sodiumtetradecylsulphate (STS. The two different types of electrophoresis allowed an evaluation of the blood proteins binding with the sclerosing agents, with a reaction time lower than 8 seconds for the AGE. Subsequently six patients underwent foam sclerotherapy and then were subdivided in group A (4 patients and B (2 patients. In group A blood sample was obtained from the ipsilateral brachial vein immediately before (T0 and repeated 1, 3, 5, and 10 minutes after injection of STS 3% injection into the GSV. In group B, the same procedure was performed with the same timing from the ipsilateral femoral vein. Free STS (fSTS and total proteinbound STS (bSTS were measured. POL mainly binds to β-globulins (11%, while STS to albumin and α-globulins (62.6% and 30.7% on the protidogram, respectively. Both in the brachial and in the femoral vein, the average fSTS was always 0. STS binds to albumin (62.6% and α-globulins (30.7%, while POL is bound mainly by the b-globulins (11%. The present paper demonstrates how the vast majority of the sclerosing agent is bound to the blood proteins, suggesting the need to look for possible sclerotherapy complications factors also in the used gas and/or in the subsequent cathabolites release.

    Background Uveitis is a term used to describe a heterogeneous group of intraocular inflammatory diseases of the anterior, intermediate, and posterior uveal tract (iris, ciliary body, choroid). Uveitis is the fifth most common cause of vision loss in high-income countries, accounting for 5% to 20% of legal blindness, with the highest incidence of disease in the working-age population. Corticosteroids are the mainstay of acute treatment for all anatomical subtypes of non-infectious uveitis and can be administered orally, topically with drops or ointments, by periocular (around the eye) or intravitreal (inside the eye) injection, or by surgical implantation. Objectives To determine the efficacy and safety of steroid implants in people with chronic non-infectious posterior uveitis, intermediate uveitis, and panuveitis.

    Children with Crohn disease have altered growth and body composition. Previous studies have demonstrated decreased protein breakdown after either corticosteroid or anti-TNF-α therapy. The aim of this study was to evaluate whole body protein metabolism during corticosteroid therapy in children with newly diagnosed Crohn disease. Children with suspected Crohn disease and children with abdominal symptoms not consistent with Crohn disease underwent outpatient metabolic assessment. Patients diagnosed with Crohn disease and prescribed corticosteroid therapy returned in 2 wk for repeat metabolic assessment. Using the stable isotopes [d5] phenylalanine, [1-(13)C] leucine, and [(15)N(2)] urea, protein kinetics were determined in the fasting state. Thirty-one children (18 controls and 13 newly diagnosed with Crohn disease) completed the study. There were no significant differences in protein breakdown or loss between patients with Crohn disease at diagnosis and controls. After corticosteroid therapy in patients with Crohn disease, the rates of appearance of phenylalanine (32%) and leucine (26%) increased significantly, reflecting increased protein breakdown, and the rate of appearance of urea also increased significantly (273%), reflecting increased protein loss. Whole body protein breakdown and loss increased significantly after 2 wk of corticosteroid therapy in children with newly diagnosed Crohn disease, which may have profound effects on body composition.

    Studies have shown that patients with acute eosinophilic pneumonia (AEP) and with initial eosinophilia have a milder disease than those with an initial normal peripheral eosinophil count (PEC). We investigated the effect of a rapid corticosteroid tapering strategy in AEP patients with initial eosinophilia. We performed a prospective cohort study in patients with AEP with initial eosinophilia (n = 14) who stopped corticosteroid treatment after achieving clinical stabilization compared with AEP patients with an initial normal PEC (n = 45) who received 2-week treatment with corticosteroid. In total, 59 AEP patients were identified. The median duration of corticosteroid treatment was 4 days (interquartile ranges (IQR), 3-4) in patients with initial eosinophilia and 14 (IQR, 14-14) days in patients with initial normal PEC. No treatment failure occurred in the group with initial eosinophilia; one treatment failure case occurred in the group with an initially normal PEC. The median time to overall clinical stabilization was 3 days, and time to complete resolution of all symptoms and clinical instabilities from diagnosis was 4 days in AEP patients with initial eosinophilia. Both were significantly shorter than those) in the initially normal PEC group, which were 5 and 7 days respectively (both P eosinophilia, and additional medications to relieve adverse effects were only needed in AEP patients with initially normal PEC. Rapid corticosteroid tapering may be an acceptable treatment strategy for managing AEP patients with initial eosinophilia. © 2015 Asian Pacific Society of Respirology.

    Corticosteroids can induce the synthesis of EBV antigens in the Burkitt lymphoma line Daudi. As early as 12 h after application of the drug, an increase of EA-positive cells can be seen, the maximum induction being reached after 2 days. Nanogram amounts per ml of hormone are sufficient for measurable effects. Early antigen induction by corticosteroids does not require replication of viral DNA. Induction by corticosteroid differs from induction by other systems in two major respects: (1) it does not cooperate with other inducers, and (2) it is specifically inhibited by 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Induction by corticosteroids, however, shares at least one retinoic acid-sensitive step with induction by chemicals such as TPA, 5-iodo-2-deoxyuridine (IdUrd), n-butyric acid (n-BA) or inducing serum factor. This study defines three qualitatively different effects of TPA in Daudi cells: an inhibitory effect on EBV induction by corticosteroids and two differential types of synergistic effects with serum factor or n-BA, respectively. In this particular cell line, TPA exhibits no inducing capacity when applied alone.

    Full Text Available A validated ovine model of osteoporosis achieves severe bone loss in a relatively short period. This study investigated if osteoporotic features persist in this model after cessation of corticosteroid administration. Methods. Osteoporosis was induced in nine ewes by chronic corticosteroid injection, ovariectomy, and low calcium diet. Six ewes were used as controls. Bone mineral density (BMD of the lumbar spine (LS and body weight were assessed at regular intervals. After five months, corticosteroid treatment was withdrawn systematically over one month. Three months later, all animals were euthanised, and the LS was collected for histomorphometric analysis. Results. BMD in the LS of osteoporotic sheep was 25% lower than control sheep. Body weight of osteoporotic sheep was reduced in the first month of the corticosteroid withdrawal period but returned to baseline level thereafter. Trabecular bone volume of LS in osteoporotic sheep was 27% lower than controls and showed a heterogeneous structure. Conclusions. Osteoporotic characteristics remain in the vertebra after ceasing corticosteroid administration providing an opportunity to evaluate potential systemic or local treatments in vivo under realistic physiological conditions. The microstructural arrangement of vertebral trabecular bone in sheep is similar to humans demonstrating further relevance of this model for preclinical investigations.

    Treatment options for immune thrombocytopenia (ITP) in pregnancy are limited, and evidence to guide management decisions is lacking. This retrospective study of singleton pregnancies from 2 tertiary centers compared the effectiveness of intravenous immunoglobulin (IVIg) and corticosteroids in treatment of ITP. Data from 195 women who had 235 pregnancies were reviewed. Treatment was not required in 137 pregnancies (58%). Of the remaining 98 pregnancies in 91 women, 47 (48%) were treated with IVIg and 51 were treated with corticosteroids as the initial intervention. Mean maternal platelet count at birth did not differ between groups (IVIg 69 × 10(9)/L vs corticosteroids 77 × 10(9)/L; P = .71) nor did the proportion of mothers who achieved a platelet count response (IVIg 38% vs corticosteroids 39%; P = .85). There were no fatal or severe maternal, fetal, or neonatal hemorrhages. Of 203 neonates in whom platelet counts were available, 56 (28%) had a birth platelet count <150 × 10(9)/L and 18 (9%) had platelet counts <50 × 10(9)/L. Nadir platelet counts for most affected neonates occurred at birth, although for some neonates, nadir platelet counts occurred up to 6 days postnatally. Intracranial hemorrhage was noted in 2 neonates (nadir platelet counts were 135 and 18 × 10(9)/L). There were no neonatal deaths. The majority of pregnant women with a history of ITP did not require treatment, and neonatal outcomes were comparable for mothers who received IVIg or corticosteroids for treatment of maternal ITP.

    Full Text Available Abstract Background The management of background corticosteroid therapy in rheumatology clinical trials poses a major challenge. We describe the consensus methodology used to design an algorithm to standardize changes in corticosteroid dosing during the Randomized Placebo Phase Study of Rilonacept in Systemic Juvenile Idiopathic Arthritis Trial (RAPPORT. Methods The 20 RAPPORT site principal investigators (PIs and 4 topic specialists constituted an expert panel that participated in the consensus process. The panel used a modified Delphi Method consisting of an on-line questionnaire, followed by a one day face-to-face consensus conference. Consensus was defined as ≥ 75% agreement. For items deemed essential but when consensus on critical values was not achieved, simple majority vote drove the final decision. Results The panel identified criteria for initiating or increasing corticosteroids. These included the presence or development of anemia, myocarditis, pericarditis, pleuritis, peritonitis, and either complete or incomplete macrophage activation syndrome (MAS. The panel also identified criteria for tapering corticosteroids which included absence of fever for ≥ 3 days in the previous week, absence of poor physical functioning, and seven laboratory criteria. A tapering schedule was also defined. Conclusion The expert panel established consensus regarding corticosteroid management and an algorithm for steroid dosing that was well accepted and used by RAPPORT investigators. Developed specifically for the RAPPORT trial, further study of the algorithm is needed before recommendation for more general clinical use.

    Overload tendon injuries are frequent in recreational and elite sports. The optimal treatment strategy remains unknown, but local administration of corticosteroids is one common treatment option. The direct effects of the corticosteroid administration on the tissue are not fully understood. The present study examined the biomechanical effects of intratendinous corticosteroid injections on healthy rat-tail tendon collagen fascicles. A total of 24 Wistar male rats were divided into (A) a corticosteroid group where the animals were injected in the tail tendon with methylprednisolone acetate, 1.0 mL of 40 mg/mL mixed with 1.0 mL 9% saline (n=12), and (B) a control group that was injected with 9% saline (n=12). Three days after the injections, the animals were sacrificed and single individual collagen fascicles were collected and underwent displacement to failure. Corticosteroid administration significantly reduced tensile fascicle yield strength by 16% and Young's modulus by 14% compared with sham treatment (10.5+/-0.8 vs 12.4+/-0.5 MPa, P< or =0.05, and 537+/-27 vs 641+/-30 MPa, P<0.05, respectively), while the strain properties were unaffected. Peak stress was similar between the two groups. There was no difference in fascicle diameter between the two groups.

    In sarcoidosis, peripapillary subretinal neovascularization is rare. The role of corticosteroid therapy for subretinal neovascularization is controversial. A 38-year-old female patient weighing 38 kg with histologically diagnosed sarcoidosis presented with peripapillary subretinal neovascularization, retinal phlebitis, a hyperemic disc, and snowball vitreous opacities in the left eye. Oral betamethasone therapy at an initial dose of 3 mg/day reduced the size of subretinal neovascular membrane, and the membrane became fibrous. Despite the total initial 140 mg of betamethasone given over 2.5 months and the additional total 700 mg of prednisolone given over the next 2 months, the subretinal neovascularization recurred. Six months after the first recurrence, a second recurrence developed during the tapering-off period of oral corticosteroid therapy. At the second recurrence, the oral corticosteroid therapy was ineffective in reducing the size of the neovascular membrane. In our patient, oral corticosteroids temporarily suppressed peripapillary subretinal neovascularization but failed to prevent extension of neovascular membrane to the fovea because of recurrent sarcoidosis. Over time, oral corticosteroids appear to lose their effectiveness for treating repeated recurrence of peripapillary subretinal neovascularization associated with sarcoidosis.

    Full Text Available Ganciclovir-resistant cytomegalovirus (CMV is associated with significant morbidity in solid organ transplant recipients. Management of ganciclovir-resistant CMV may be complicated by nephrotoxicity which is commonly observed with recommended therapies and/or rejection induced by “indirect” viral effects or reduction of immunosuppression. Herein, we report a series of four high serologic risk (donor CMV positive/recipient CMV negative kidney transplant patients diagnosed with ganciclovir-resistant CMV disease. All patients initially developed “breakthrough” viremia while still receiving valganciclovir prophylaxis after transplant and were later confirmed to exhibit UL97 mutations after failing to eradicate virus on adequate dosages of valganciclovir. The patients were subsequently and successfully treated with reduced-dose (1-2 mg/kg cidofovir and CMV-hyperimmune globulin, given in 2-week intervals. In addition, all patients exhibited stable renal function after completion of therapy, and none experienced acute rejection. The combination of reduced-dose cidofovir and CMV-hyperimmune globulin appeared to be a safe and effective regimen in patients with mild disease due to ganciclovir-resistant CMV.

    Hyperplasia of airway smooth muscle (ASM) is a feature of the remodelled airway in asthmatics. We examined the antiproliferative effectiveness of the corticosteroid dexamethasone on expression of the key regulator of G(1) cell cycle progression-cyclin D1-in ASM cells from nonasthmatics and asthmatics stimulated with the mitogen platelet-derived growth factor BB. While cyclin D1 mRNA and protein expression were repressed in cells from nonasthmatics in contrast, cyclin D1 expression in asthmatics was resistant to inhibition by dexamethasone. This was independent of a repressive effect on glucocorticoid receptor translocation. Our results corroborate evidence demonstrating that corticosteroids inhibit mitogen-induced proliferation only in ASM cells from subjects without asthma and suggest that there are corticosteroid-insensitive proliferative pathways in asthmatics.

    A reflectance spectrophotometric method for evaluation of the skin blanching response to topical corticosteroids was evaluated. This blanching response is used, for drug development and regulatory purposes, to assess potency and bioequivalence of topical corticosteroid products. The common method involves the use of a human rater to measure blanching response in the skin. This study evaluated an instrumental alternative to the human rater and used this method to measure the differences between a number of brand name and generic topical corticosteroid products (six creams and six ointments). Products were applied to the forearms of normal volunteers and the blanching responses were assessed after 6 and 16 hours in both occluded and non-occluded skin sites. Only the fluocinolone acetonide generic and brand name preparations were different from each other. The spectrophotometric method proved to be equivalent but not superior to the standard human observer method.

    We report 2 pediatric patients who presented initially with seizures followed by subacute language regression characterized by a verbal auditory agnosia. These previously normal children had no evidence of expressive aphasia during their symptomatic periods. Further, in both cases, auditory agnosia was associated with sleep-activated electroencephalographic (EEG) epileptiform activity, consistent with Landau-Kleffner syndrome. However, both cases are unique since the episodic auditory agnosia and sleep-activated EEG epileptiform activity rapidly responded to combination therapy with pulse benzodiazepine and corticosteroids. Further, in each case, recurrences were characterized by similar symptoms, EEG findings, and beneficial responses to the pulse benzodiazepine and corticosteroid therapy. These observations suggest that pulse combination high-dose corticosteroid and benzodiazepine therapy may be especially effective in Landau-Kleffner syndrome. © The Author(s) 2014.

    BACKGROUND: Maintenance therapy with oral corticosteroid (OCS) is used, although not based on evidence, for patients with severe asthma, but OCS is associated with serious adverse effects; therefore, management strategies aimed at steroid sparing are important. OBJECTIVE: To provide an update...... oral steroidsparing strategies (n = 5), the following lowered the OCS dose: Internet-based tapering strategy (44% reduction in OCS dose), inhaled corticosteroids (mometasone furoate [mean daily OCS dose reduction of 39% and 31% in patients treated with 800 mcg/day and 1600 mcg/day, respectively......), masitinib (78% reduction in OCS dose), mepolizumab (50%83% reduction in OCS dose), and omalizumab (30%64% of enrolled patients achieved a reduction in OCS dose, and one study reported a dose reduction of 45%).

    Živić Ljubica

    2012-01-01

    Full Text Available Introduction. Sudden hearing loss is a clinical entity of ambiguously defined aetiology manifested by hearing loss of more than 30 dB on three contiguous frequencies occurring within 72 hours. The lack of standard therapy protocol led to the use of variety of different therapies, thus making difficult objective quantification of their effect. Objective. The aim of the study was to present our experience in the treatment of sudden hearing loss with administration of vasoactive and corticosteroid therapy. Methods. Our research included 59 hospitally treated patients with a sudden hearing loss. During the period 1995-2004, 37 patients were treated using vasoactive agents (xanthinol nicotinate and pentoxifylline, and from 2004-2009, 22 patients were treated using parenteral corticosteroids (dexamethasone. All patients had unilateral sensorineural hearing loss of different level at frequencies from 500-4000 Hz, while other diagnostic procedures (laboratory tests, internist and neurology examinations, X-ray were within normal limits. Evaluation of therapy effect was done by follow-up of hearing threshold changes and subjective complaints. Results. The results showed that full recovery was achieved in patients with a mild and not fully severe hearing loss, with the majority of those (73% under corticosteroid treatment. In these patients recovery was also achieved more rapidly. A partial recovery of hearing was detected in patients with hearing loss of more than 80 dB, and mostly in patients treated with corticosteroids. Conclusion. Although statistical evaluation does not indicate significant differences between the application of vasoactive drugs or corticosteroids, clinical findings support advantages of corticosteroid therapy. Treatment of hearing loss, although controversial, requires change of some up-to-now used agents. Advantages should go in favour of contricosteroids.

However, corticosteroids have a considerable number of side effects, including hypertension, diabetes, lipid disorders, sleep apnea, osteoporosis, myopathy, and disorders of coagulation and fibrinolysis, which are components of Cushing’s syndrome (CS. Corticosteroid-induced side effects are dependent on the formulation, route, dose, and time of exposure. However, the underlying pathogenetic mechanisms have not been clearly defined. A large body of evidence supports the role of an imbalance between vasoconstriction and vasodilation with possible links to nitric oxide, prostanoids, angiotensin II, arginine vasopressin, endothelins, catecholamines, neuropeptide Y, and atrial natriuretic peptide. Increased oxidative stress, renin–angiotensin system activation, increased pressor response, metabolic syndrome, and sleep apnea appear to be pathogenetically involved as well. The ideal treatment is the withdrawal of corticosteroids, which is most often impossible due to the exacerbation of the underlying disease. Alternatively, a careful plan, including the proper selection of the formulation, time, and route, should be made, and each side effect should be treated properly. The focus of the research should be to develop synthetic corticosteroids with anti-inflammatory effects but fewer metabolic effects, which so far has been unsuccessful.Keywords: corticosteroids, hypertension, iatrogenic Cushing’s syndrome

  12. Fresh water acclimation elicits a decrease in plasma corticosteroids in the euryhaline Atlantic stingray, Dasyatis sabina.

    Evans, Andrew N; Nunez, B Scott

    2015-10-01

    It is thought that the elasmobranch corticosteroid hormone 1α-hydroxycorticosterone (1α-B) functions as both a glucocorticoid (GC) and mineralocorticoid (MC). Classical antinatriuretic MC activities would run counter to the osmoregulatory strategy of euryhaline elasmobranchs acclimating to fresh water (FW). Therefore we hypothesize that FW acclimation will be accompanied by a decrease in plasma corticosteroids in these animals. However, events that activate the "fight-or-flight" response could mask changes associated with acclimation to lower salinities. To better define the MC role of corticosteroids in elasmobranchs, we designed a transfer system that allows the acclimation of Atlantic stingrays (Dasyatis sabina) from seawater (SW) to FW over 12h while minimizing other extraneous stressors. Blood and interrenal glands were sampled from one group of stingrays 24h after FW transfer, while another group was sampled two weeks after FW transfer. Two other groups served as mock-transfer controls in that they were treated and sampled in the same way, but remained in SW for the entire period. Plasma corticosteroids, osmolality, chloride, and urea were significantly lower in FW-acclimated stingrays (compared to mock-transfer stingrays) 24h after FW transfer. This pattern remained after two weeks in FW, with the exception that plasma corticosteroids returned to pre-acclimation levels. There were no significant differences between experimental groups in interrenal levels of mRNAs encoding key steroidogenic proteins (steroidogenic acute regulatory protein and cholesterol side chain cleavage enzyme). Temporally decreased corticosteroid levels during FW acclimation are consistent with the unique strategy of euryhaline elasmobranchs, whereby lower plasma osmolality is maintained in FW vs. SW environments to reduce hydromineral gradients.

    PURPOSE Acute sinusitis is a common condition in ambulatory care, where it is frequently treated with antibiotics, despite little evidence of their benefit. Intranasal corticosteroids might relieve symptoms; however, evidence for this benefit is currently unclear. We performed a systematic review and meta-analysis of the effects of intranasal corticosteroids on the symptoms of acute sinusitis. METHODS We searched MEDLINE, EMBASE, the Cochrane Central register of Controlled Trials (CENTRAL), and Centre for Reviews and Dissemination databases until February 2011 for studies comparing intranasal corticosteroids with placebo in children or adults having clinical symptoms and signs of acute sinusitis or rhinosinusitis in ambulatory settings. We excluded chronic/allergic sinusitis. Two authors independently extracted data and assessed the studies’ methodologic quality. RESULTS We included 6 studies having a total of 2,495 patients. In 5 studies, antibiotics were prescribed in addition to corticosteroids or placebo. Intranasal corticosteroids resulted in a significant, small increase in resolution of or improvement in symptoms at days 14 to 21 (risk difference [RD] = 0.08; 95% CI, 0.03–0.13). Analysis of individual symptom scores revealed most consistently significant benefits for facial pain and congestion. Subgroup analysis by time of reported outcomes showed a significant beneficial effect at 21 days (RD = 0.11; 95% CI, 0.06–0.17), but not at 14 to 15 days (RD = 0.05; 95% CI, −0.01 to 0.11). Meta-regression analysis of trials using different doses of mometasone furoate showed a significant dose-response relationship (P=.02). CONCLUSIONS Intranasal corticosteroids offer a small therapeutic benefit in acute sinusitis, which may be greater with high doses and with courses of 21 days’ duration. Further trials are needed in antibiotic-naïve patients. PMID:22585889

    Background:Coronary artery lesions (CALs) are known to be the main complication in children with Kawasaki disease (KD).Instead of intravenous immunoglobulin (IVIG),corticosteroid therapy has been accepted to be used for children with KD who are unresponsive to IVIG.This study aimed to evaluate risk factors for CALs in children with KD.Methods:We retrospectively reviewed the clinical records of 2331 children with KD from January 2005 to December 2014.To identify the independent risk factors for CALs,multivariable logistic regression models were constructed using significant variables identified from univariate logistic regression analysis.Results:The incidence of CALs was 36.0% (840 of 2331),including 625 (26.8%) coronary artery dilations and 215 (9.2%) coronary artery aneurysms (CAAs).Multivariable logistic regression analysis identified that male,incomplete KD,longer fever duration,and C-reactive protein (CRP) > 100 mg/L were independent risk factors for coronary artery dilatations.On the other hand,male,incomplete KD,longer fever duration,prolonged days of illness at the initial treatment,corticosteroid therapy,sodium ≤133 mmol/L,and albumin <35 g/L were the independent risk factors for CAAs.In addition,corticosteroid therapy,prolonged days of illness at the initial treatment,and albumin <35 g/L were the independent risk factors for giant CAAs.Conclusions:CALs might be associated with male sex,incomplete KD,longer fever duration,prolonged days of illness at the initial treatment,albumin <35 g/L,sodium ≤ 133 mmol/L,CRP > 100 mg/L,and corticosteroid therapy.Corticosteroid therapy was an independent risk factor for CAAs and giant CAAs.Thus,corticosteroids should be used with caution in the treatment of KD with the risk for CALs.

    The beneficial effect of corticosteroids has been well established, particularly in patients free of infection with the human immunodeficiency virus. In intensive care units, the high risks of infection to which patients are exposed specifically could offset the neurological benefit of corticosteroids. The purpose of the study was to assess the effects of corticosteroids in adult patients with tuberculous meningitis admitted to intensive care unit. Retrospective cohort study including all adult patients admitted to intensive care unit for tuberculous meningitis between January 1993 and December 2005. A propensity score case matching was performed using a multivariable logistic regression model, and matched pairs were examined for baseline characteristics and outcome by using conditional regression model. A multivariate Cox's proportional hazard model was used to assess the effects of corticosteroids in all patients adjusting for propensity score. The primary outcome was mortality at 60 days and the secondary outcome was the density of incidence of nosocomial infections. Two hundred and seventy patients were included. The mean age was 38+/-17 years, and the Glasgow coma scale was 12+/-3. The overall mortality was 43.3%. Ninety-four patients who had received corticosteroids were matched to 94 patients untreated with corticosteroids by the propensity score. The baseline characteristics were similar in the two groups except for hydrocephalus, which was more frequent in the group corticosteroids. The mortality rate was 47.9% in group Corticosteroids and 52.1% in group No corticosteroids (P=0.77). The case fatality rate in stage III patients, according to the British Medical Research Council criteria, was 61.5% in the group Corticosteroids versus 74.1% in the group No corticosteroids (P=0.33). Nosocomial infections were observed in 19.1 by 1000 days patient in group Corticosteroids versus 16.1 by 1000 days patient in group No corticosteroids (P=0.4). The outcome in all

    2015-07-08

    The treatment of polymyositis is based on corticosteroid therapy, with addition of azathioprine for non responsive cases or as an attempt to diminish corticosteroids requirements. However, there is no clear evidence of its benefit in controlling symptoms. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified only one systematic review including one pertinent randomized trial. We generated a summary of findings following the GRADE approach. We concluded there is uncertainty if azathioprine improves or not muscular strength in polymyositis because the certainty of the evidence is very low.

  17. Anaphylaxis at image-guided epidural pain block secondary to corticosteroid compound.

    Anaphylaxis during image-guided interventional procedures is a rare but potentially fatal event. Anaphylaxis to iodinated contrast is an established and well-recognized adverse effect. However, anaphylaxis to some of the other frequently administered medications given during interventional procedures, such as corticosteroids, is not common knowledge. During caudal epidural injection, iodinated contrast is used to confirm needle placement in the epidural space at the level of the sacral hiatus. A combination of corticosteroid, local anesthetic, and saline is subsequently injected. We describe a very rare case of anaphylaxis to a component of the steroid medication instilled in the caudal epidural space.

    This is a report of one patient who developed chronic progressive radiation myelopathy at a gap of two portals 31 months after 40 Gy irradiation. He presented an unusual clinical course with over 5 years and 6 months administration of oral corticosteroid, very slow progression and long-lasting presentation of Gd-DTPA enhanced area in the suffered cord by MRI. It is suggested that corticosteroid administration from initial onset for a long period may change the natural course of radiation myelopathy, that is, may delay progress of it. (author)

    Propylene glycol (PG) is considered to be a ubiquitous formulary ingredient used in many personal care products and pharmaceutical preparations. It is an organic compound commonly found in topical corticosteroids (CS). Cutaneous reactions to PG are mostly irritant, but allergic contact dermatitis to PG is well-documented. Cosensitization to PG and topical CS can occur, making it challenging to choose the appropriate topical CS in a PG-allergic patient. This review is aimed at guiding clinicians in the selection of a suitable topical corticosteroid when presented with patients allergic to PG.

    The association of Kaposi's sarcoma with malignant lymphoreticular diseases and immunosuppressive therapy is well documented. This report describes an elderly man who presented with fulminant Wegener's granulomatosis that responded to treatment with cyclophosphamide and corticosteroids. Rapidly progressing cutaneous Kaposi's sarcoma developed ten weeks after the start of immunosuppressive therapy yet regressed on discontinuation of the corticosteroid therapy, despite continuation of cyclophosphamide therapy. To our knowledge, this is the first reported case of Kaposi's sarcoma occurring in association with Wegener's granulomatosis. The literature on Kaposi's sarcoma in immunosuppressed patients is reviewed.

    Mucormycosis is harmless to a healthy person, but can cause opportunistic infections in immunocompromised patients, and once it has invaded internal organs is frequently fatal. Traumatic optic neuropathy is a rare complication of maxillofacial trauma. Management is controversial, and there are no treatment guidelines in the literature. The main methods of treatment of this condition employed today are high-dose corticosteroids and surgical optic nerve decompression, either alone or in combination. In this case, the patient was in good health, but received high-dose corticosteroids for 2 weeks, which temporarily diminished immune response and permitted the development of mucormycosis.

    Chemosignals play a crucial role in social and sexual communication among inter- and intra-species. Chemical cues are bound with protein that is present in the pheromones irrespective of sex are commonly called as pheromone binding protein (PBP). In rats, the pheromone compounds are bound with low molecular lipocalin protein α2u-globulin (α2u). We reported farnesol is a natural endogenous ligand (compound) present in rat preputial gland as a bound volatile compound. In the present study, an attempt has been made through computational method to evaluating the binding efficiency of α2u with the natural ligand (farnesol) and standard fluorescent molecule (2-naphthol). The docking analysis revealed that the binding energy of farnesol and 2-naphthol was almost equal and likely to share some binding pocket of protein. Further, to extrapolate the results generated through computational approach, the α2u protein was purified and subjected to fluorescence titration and binding assay. The results showed that the farnesol is replaced by 2-naphthol with high hydrophobicity of TYR120 in binding sites of α2u providing an acceptable dissociation constant indicating the binding efficiency of α2u. The obtained results are in corroboration with the data made through computational approach.

    Full Text Available Epidemiological studies have shown a strong association between dermatitis and stroke. Systemic corticosteroid, the mainstay treatment for dermatitis, could enhance the atherosclerotic process. Traditional Chinese Medicine (TCM has been used for dermatitis to decrease the side effects of corticosteroid. However, the different stroke risk in dermatitis patients treated with systemic corticosteroid or TCM remains unclear. This study identified 235,220 dermatitis patients and same comorbidity matched subjects between 2000 and 2009 from database of NHRI in Taiwan. The two cohorts were followed until December 31, 2011. The primary outcome of interest was new diagnosis of stroke. The crude hazard ratio (HR for future stroke among dermatitis patients treated with systemic corticosteroid was 1.40 (95% CI, 1.34–1.45; P<0.0001 and TCM was 1.09 (95% CI, 1.05–1.13; P<0.0001. The log-rank test showed a higher cumulative incidence of ischemic stroke in the patient treated with only systemic corticosteroid group than that treated with systemic corticosteroid and TCM, only TCM, and neither systemic corticosteroid nor TCM in the matched cohort during the follow-up period (P<0.0001. We demonstrated that patients treated with systemic corticosteroid had an increased risk of stroke and that the risk probably decreased by TCM treatment.

    Diagnosis and management of critical illness-related corticosteroid insufficiency (CIRCI) in children continues to remain difficult and controversial in that no consensus for either exists among pediatric critical care physicians. Critical illness-related corticosteroid insufficiency is defined as a corticosteroid response that is inadequate for the severity of the illness experienced by the patient. Critical illness-related corticosteroid insufficiency manifests as an insufficient corticosteroid mediated down-regulation of proinflammatory cytokines, due to either corticosteroid tissue resistance and/or inadequate circulating levels of cortisol. The tissue resistance is likely due to alterations in the functionality of the intracellular receptor for corticosteroids, the glucocorticoid receptor (GR). This article details the role of the GR during critical illness with a focus upon the measurement of the GR, as a potentially important means by which to clinically assess the level of corticosteroid tissue-resistant in patients suspected of CIRCI. Measurement of the GR may be particularly useful as a means by which to determine the judicious administration of steroids, maximizing their therapeutic potential, whereas minimizing the morbidity that can be associated with their use.

    The effect of varying corticosteroid regimens on hip osteonecrosis incidence remains unclear. We performed a meta-analysis and systematic literature review to determine osteonecrosis occurrences in patients taking corticosteroids at varying mean and cumulative doses and treatment durations, and whether medical diagnoses affected osteonecrosis incidence. Fifty-seven studies (23,561 patients) were reviewed. Regression analysis determined significance between corticosteroid usage and osteonecrosis incidence. Osteonecrosis incidence was 6.7% with corticosteroid treatment of >2 g (prednisone-equivalent). Systemic lupus erythematosus patients had positive correlations between dose and osteonecrosis incidence. Each 10 mg/d increase was associated with a 3.6% increase in osteonecrosis rate, and >20 mg/d resulted in a higher osteonecrosis incidence. Clinicians must be wary of osteonecrosis in patients on high corticosteroid regimens, particularly in systematic lupus erythematosus.

    The macrophage disappearance reaction (MDR) is a suitable test for detection of cell mediated immunity against bovine gamma globulin (BGG) and human serum albumin (HSA) in guinea pigs. The MDR is a technical simple, good manipulable, and quantifiable test. The optimal test conditions for the antigens BGC and HSA are the following: Peritoneal exudat cells (PEC) were stimulated with paraffin oil. On the 5th day after receiving oil the animals were injected with 80 microgram BGG or 30 microgram HSA i.p. 5 hours later the PEC were harvested and counted. With the MDR it is possible to detect differences with respect to degree of cell-mediated immunity. Supernatants of sensitized lymphocytes produces the MDR too.

    We studied anthrax immune globulin intravenous (AIG-IV) use from a 2009–2010 outbreak of Bacillus anthracis soft tissue infection in injection drug users in Scotland, UK, and we compared findings from 15 AIG-IV recipients with findings from 28 nonrecipients. Death rates did not differ significantly between recipients and nonrecipients (33% vs. 21%). However, whereas only 8 (27%) of 30 patients at low risk for death (admission sequential organ failure assessment score of 0–5) received AIG-IV, 7 (54%) of the 13 patients at high risk for death (sequential organ failure assessment score of 6–11) received treatment. AIG-IV recipients had surgery more often and, among survivors, had longer hospital stays than did nonrecipients. AIG-IV recipients were sicker than nonrecipients. This difference and the small number of higher risk patients confound assessment of AIG-IV effectiveness in this outbreak. PMID:27983504

    Equine antithymocyte globulin combined with azathioprine and prednisone as immunosuppressive therapy in 50 transplant recipients prolonged allograft survival and seemed to modify the severity of rejection episodes. Although nine patients died from a variety of causes, only three kidneys were lost to rejection, one of which was hyperacute. There were no serious untoward hematologic or systemic effects caused by the ATG, and all patients completed the course of therapy. Infection, a serious and frequent complication of transplant patients, was encountered no more often than in other transplant series not using ALG. The data pertaining to the clinical value of ATG, although suggestive in terms of its immunosuppressive effects, is still not conclusive; and a definitive answer to this question awaits further evaluation in a series of cadaveric recipients in a randomized-double-blind study.

    A new chromatofocusing medium, MonoP, was used for fast (60 min or less) separations of human serum proteins. Separations in the broad pH interval 6.0-3.8 were analysed by fused rocket immunoelectrophoresis to identify a number of proteins, and by gradient gel electrophoresis to determine the molecular weight distribution of the eluted material. To illustrate further the high resolving power of chromatofocusing, narrow pH intervals of about 0.5 pH units were used to study the microheterogeneity of alpha 1-antitrypsin and Gc-globulin. Due to its high resolving power and preparative capacity, chromatofocusing is attractive as the first dimension in two-dimensional techniques for the resolution of complex protein mixtures.

    The aim of this study was to develop bread containing a papain hydrolysate of bovine α- and β-globulins (GPH) with in vitro and in vivo antihypertensive activities. The physical characteristics of the formulated bread were assessed over a six day period and results suggested that the overall quality and acceptance of bread was not affected by the inclusion of GPH at a concentration of 4% (w/w). Bright field light microscopy and confocal scanning laser microscopy images were used to visualize the main ingredients of the bread. In addition, the antihypertensive activity of the bread was assessed in spontaneously hypertensive rats (SHRs) over a 24 h period where a maximum significant decrease in systolic blood pressure of 36.2 ± 1.9 mmHg was observed 8 h after oral administration. Results demonstrate that the antihypertensive activity of GPH was resistant to the baking process and shows potential for use as a functional antihypertensive ingredient.

    Leflunomide is an effective drug used in the treatment of rheumatoid arthritis. Here we report the findings of an open-label pilot study, which found that leflunomide is also an effective treatment for myasthenia gravis (MG). This study recruited 15 corticosteroid-dependent MG patients. For 6 months, leflunomide 20 mg was given to these patients daily along with prednisone. The quantitative myasthenia gravis (QMG) scores and MG activities of daily living (MG-ADL) profiles were measured in these MG patients. After 6 months of treatment, 9 of the 15 patients enrolled in this study showed improvements in both QMG and MG-ADL. The mean QMG scores (13.4 to 8.5) and MG-ADL profiles (5.8 to 2.8) were significantly decreased (P = 0.01, 0.006 respectively). Furthermore, we found that the mean corticosteroid doses were reduced after treatment with leflunomide (24.3 to 12.3 mg per day). Leflunomide is a well-tolerated and efficacious treatment for corticosteroid-dependent MG, which may also enable lower doses of corticosteroids to be administered.

    Administering local anesthetic or corticosteroid injections in professional athletes to allow return to play is common but has traditionally been viewed as suspect and taboo. The skepticism surrounding therapeutic injections stems predominantly from anecdotal experience as opposed to scientific data. The purpose of this paper is to evaluate the current use of corticosteroid injections for muscle strains and ligaments sprains in the National Football League to document player's ability to return to play and possible adverse effects. Athletes from a single National Football League team who received at least one corticosteroid or anesthetic injection for either a muscle strain or ligament sprain during three consecutive seasons were retrospectively reviewed. Thirty-seven injections were given over the three seasons. Injections were either performed blindly or by using ultrasound guidance. Twice as many defensive players were injected than offensive players. The average number of days of conservative treatment before injection was 6.5 days. All players returned to play after injection. There were no complications from any of the injections. Seventeen (55%) players did not miss a single game, and nine (30%) did not miss a single day. Quadriceps strains were associated with the most missed games (four) and the most missed days (36.5). Proximal hamstring strains were second with an average of three missed games and 28 missed days. Corticosteroid injections are a safe and effective therapeutic intervention for treating muscle strains and ligament sprains in order to enable athletes to return to competition earlier.

    Conclusions: The 6 month manegement of asthma in the actual clinical setting, including regular ICS use, might have a harmful influence on the bone status of female asthmatic patients. It may be necessary to manage and treat female patients for potent corticosteroid-induced osteoporosis, although further analyses of bone status in asthma patient ICS users will be required.

    Verhaar, J A; Walenkamp, G H; van Mameren, H; Kester, A D; van der Linden, A J

    1996-01-01

    We performed a prospective, randomised trial on 106 patients to compare the effects of local corticosteroid injections with physiotherapy as advocated by Cyriax in the treatment of tennis elbow. The main outcome measures were the severity of pain, pain provoked by resisted dorsiflexion of the wrist, and patient satisfaction. At six weeks 22 of 53 patients in the injection group were free from pain compared with only three in the physiotherapy group. In the corticosteroid-treated group 26 patients had no pain on resisted dorsiflexion of the wrist compared with only three in the physiotherapy group. Thirty-five patients who had injections and 14 who had physiotherapy were satisfied with the outcome of treatment at six weeks. At the final assessment there were 18 excellent and 18 good results in the corticosteroid group and one excellent and 12 good results in the physiotherapy group. There was a significant increase in grip strength in both groups but those with injections had a significantly better result. After one year there were no significant differences between the two groups. Half of the patients, however, had received only the initial treatment, 20% had had combined therapy and 30% had had surgery. We conclude that at six weeks, treatment with corticosteroid injections was more effective than Cyriax physiotherapy and we recommend it because of its rapid action, reduction of pain and absence of side-effects.

  12. The effectiveness of corticosteroid injection in the treatment of plantar fasciitis.

    Science.gov (United States)

    Ang, Teck Wee Andrew

    2015-08-01

    Plantar fasciitis is a common cause of heel pain in adults. Although it is usually a self-limiting condition, the pain may become prolonged and severe enough to cause significant distress and disruption to the patient's daily activities and work. PubMed and Cochrane Central Register of Controlled Trials databases were searched for randomised controlled trials (RCTs) and a total of ten RCTs were selected for evaluation. These RCTs involved the use of either palpation- or ultrasonography-guided corticosteroid injections in patients diagnosed with plantar fasciitis. All placebo-controlled RCTs showed a significant reduction in pain with the use of corticosteroid injections. Some studies also showed that corticosteroid injections yielded better results than other treatment modalities. However, it is evident from these studies that the effects of corticosteroid injections are usually short-term, lasting 4-12 weeks in duration. Complications such as plantar fascia rupture are uncommon, but physicians need to weigh the treatment benefits against such risks.

  13. New patents of fixed combinations of nasal antihistamines and corticosteroids in allergic rhinitis.

    2013-09-01

    During the last few years, fixed combinations of intranasal antihistamines and corticosteroids have been introduced for treatment of allergic rhinitis. The aim of this systematic review was to assess recent patents and clinical evidence for fixed combinations of intranasal antihistamines and intranasal corticosteroids in allergic rhinitis. Data base searches revealed that intranasal combinations of the antihistamine azelastine with the corticosteroids mometasone furoate, ciclesonide and fluticasone propionate, respectively, have been patented. Four randomized, double-blinded, parallel-group, placebo-controlled, multicenter trials sponsored by the manufacturer evaluated the fixed combination of intranasal azelastine 125 µg and fluticasone propionate 50 µg administered as one dose per nostril b.i.d. in patients with moderate-to-severe symptomatic allergic rhinitis ≥ 12 years of age. Three of the studies were published as a meta-analysis which found the fixed combination of azelastine and fluticasone propionate statistically significantly more efficacious in reducing baseline total nasal symptom score by 5.7 as compared to azelastine (4.4; P antihistamines and corticosteroids are needed, especially, in primary care settings and in children before fixed combination treatment can be considered first line therapy in allergic rhinitis. Fixed combination treatment of azelastine and fluticasone propionate may offer additional benefit to selected populations of adolescents and adults with moderate-to-severe symptoms.

    Topical corticosteroids and corticosteroid combinations are the principal treatments in psoriasis. The aim of this study was to investigate published literature dealing with medical adherence to topical corticosteroid or corticosteroid combinations in patients with psoriasis. Systematic electronic searches in English language literature were done until September 2015 without publication date restriction. We identified 11 studies consisting of five surveys, two prospective studies, one qualitative study, one mixed-method study, one register study, and one interventional study. Observation periods varied and rates of nonadherence ranged from 8% to 88.3%. The rates were reported by patients on eight nonvalidated scales and one validated scale, measured by medication weight in two studies, and in two studies rates of nonadherence were measured using prescription registers. Thirty-four multifactorial determinants of nonadherence were found. One designed intervention consisted of a disease management program, which improved adherence in the study period. Overall, the studies included were heterogeneous in design and had a high risk of bias. To improve health outcome in topical treatment of psoriasis, further studies should be conducted addressing determinants of nonadherence and test interventions to improve adherence. Validated measurements of medical nonadherence, prescription registers, or medication-weight are needed.

    Aim: The resurgence of severe acute respiratory syndrome (SARS) is still a threat because the causative agent remaining in animal reservoirs is not fully understood,and sporadic cases continue to be reported. Developing high titers of anti-SARS hyperimmune globulin to provide an alternative pathway for emergent future prevention and treatment of SARS. Methods: SARS coronavirus (CoV)F69 (AY313906)and Z2-Y3 (AY394989) were isolated and identified from 2 different Cantonese onset SARS patients. Immunogen was prepared from SARS-CoV F69 strain. Six health horses were immunized 4 times and serum was collected periodically to measure the profile of specific IgG and neutralizing antibodies using indirect enzyme-linked immunosorbent assay and a microneutralization test. Sera were collected in large amounts at the peak, where IgG was precipitated using ammonium sulphate and subsequently digested with pepsin. The product was then purified using anion-exchange chromatography to obtain F(ab')2 fragments. Results: The specific IgG and neutralizing antibody titers peaked at approximately week 7 after the first immunization, with a maximum value of 1:14210. The sera collected at the peak were then purified. Fragment of approximately 15 g F(ab')2 was obtained from 1 litre antiserum and the purity was above 90% with the titer of 1:5120, which could neutralize the other strain (SARS-CoV Z2-Y3) as well. Conclusion: This research provides a viable strategy for the prevention and treatment of SARS coronavirus infection with equine hyperimmune globulin, with the purpose of combating any resurgence of SARS.

    Full Text Available Background: knee Osteoarthritis is the most common cause of musculoskeletal pain and disability. Shockwaves have been used as an alternative treatment for musculoskeletal disorders; intra-articular injection of steroid is a common treatment for osteoarthritis of the knee. This study aimed to investigate the efficacy of Shock wave therapy versus Corticosteroid intra articular injection in case of knee osteoarthritis. Methods: Sixty patients were diagnosed mild to moderate knee osteoarthritis; they were included in the study. Their ages were 43:65 years with mean age 50 ± 3.5 years. Patients were divided randomly into three equal groups, group (A received shock wave therapy, group (B received two intra-articular injections of corticosteroid at 1-month intervals and group (C received sham shock wave. The outcome measurements were Western Ontario and McMaster Universities arthritis index (WOMAC values, knee ROM, and pain severity using the visual analogue scale (VAS were recorded. The patients were evaluated for these parameters before allocated in their groups then after 1, 2, and 6months later. Results: compared to sham group there were significant improvement of VAS and ROM of shock wave group and corticosteroid injection group than sham (placebo group (p<0.000, (p<0.006, and 0.02 respectively. Furthermore there was significant improve of shock wave group than corticosteroid injection group where p was <0.000 for VAS, ROM and (WOMAC. Conclusion: The results of this study suggested that shock wave therapy may provide effective modality for relieving pain, increase Range of motion and improve function in knee osteoarthritis patient than intra articular corticosteroid injection.
