BACKGROUND Morbidly obese patients are at risk of developing insulin resistance and cardiovascular disease . Low- grade systemic inflammation is an important factor for this development . We evaluated the effect of bariatric surgery on markers of inflammation , coagulation and glucose metabolism . METHODS Ninety-seven morbidly obese patients and 17 lean subjects ( control group ) participated .  Anthropometric measurements  as well as  fasting blood sample s  were obtained at first admission , prior to surgery , and 1 year after surgery . RESULTS At admission , the morbidly obese group had significantly elevated levels of the complement components C3 and C4 compared to the lean control group ( P<0.0001 ) . Levels of C3 and C4 dropped significantly in the morbidly obese group over time ( P<0.0001 ) , and , 1 year after the operation , levels were comparable to those of the control group . The same changes were seen for markers of inflammation ( high-sensitivity C-reactive protein , tumor necrosis factor-α , interferon-γ , interleukin-1 receptor antagonist , IL-6 , and IL-13 ) , coagulation ( fibrinogen and plasminogen activator inhibitor-1 ) , and glucose metabolism ( leptin and insulin ) . There was a positive correlation between changes in C3 and body mass index , weight , coagulation parameters , inflammatory parameters , and leptin , respectively . CONCLUSIONS Bariatric surgery in morbidly obese patients  reduced weight effectively . Even more importantly , the increased levels of several risk factors associated with diabetes and cardiovascular co-morbidity normalized 1 year after surgery Introduction Morbid obesity and obstructive sleep apnea ( OSA ) interact at an inflammatory level . Bariatric surgery reduces inflammatory responses associated with obesity . Heme oxygenase-1 ( HO-1 ) is an enzyme with anti-inflammatory properties , which might be increased in morbid obesity or OSA . We studied morbidly obese patients with OSA to determine : ( a ) HO-1 plasma concentrations according to OSA severity and their relationship with insulin resistance and inflammation and ( b ) the impact of bariatric surgery on HO-1 and parameters of insulin resistance and inflammation . Material and Methods We analyzed the homeostasis model insulin resistance index ( HOMA ) and plasma concentrations of HO-1 , tumor necrosis factor alpha , interleukin-6 , interleukin-1-beta , C reactive protein ( CRP ) , and adiponectin according to polysomnography findings in 66 morbidly obese patients before bariatric surgery  and 12 months after surgery . Results Before surgery , HO-1 plasma concentrations were similar in three groups of patients with mild , moderate , and severe OSA , and correlated with HOMA ( r = 0.27 , p = 0.02 ) . Twelve months after surgery , low- grade inflammation and insulin resistance had decreased in all the groups , but HO-1 plasma concentration had decreased only in the severe OSA group ( p = 0.02 ) . In this group , the reduction in HO-1 correlated with a reduction in CRP concentrations ( r = 0.43 , p = 0.04 ) and with improved HOMA score ( r = 0.37 , p = 0.03 ) . Conclusions Bariatric surgery decreases HO-1 concentrations in morbid obesity with severe OSA , and this decrease is associated with decreases in insulin resistance and in inflammation BACKGROUND AND AIMS Obesity and physical inactivity are both associated with low- grade inflammation and endothelial dysfunction .  Bariatric surgery improves markers of inflammation and endothelial function , but it is unknown if physical training after bariatric surgery can improve these markers even further . Therefore , we aim ed to investigate the effects of Roux-en-Y gastric bypass ( RYGB ) followed by physical training on markers of low- grade inflammation and endothelial function . METHODS Sixty patients approved for RYGB underwent examinations pre-surgery , 6 , 12 , and 24 months post-surgery . Six months post-surgery , they were r and omized 1:1 to an intervention group or a control group . The interventions consisted of two weekly sessions of supervised moderate intensity physical training for a period of 26 weeks . Fasting blood sample s were analyzed for concentrations of interleukin 6 ( IL-6 ) , C-reactive protein ( CRP ) , intercellular adhesion molecule 1 ( ICAM-1 ) , tissue-type plasminogen activator antigen ( t-PA : Ag ) and von Willebr and factor ( vWF ) . RESULTS RYGB markedly improved markers of inflammation ( IL-6 , CRP ) ( p < 0.001 ) and endothelial function ( ICAM-1 , t-PA : Ag , vWF ) ( p < 0.05 ) , and the improvements were sustained 24 months post-surgery ( p < 0.01 ) , except for the effects on vWF . We found no correlations between the changes in weight or BMI and the changes in markers of inflammation and endothelial function , except that the change in vWF was found to be inversely correlated with the changes in weight and BMI . We observed no effects of supervised physical training on markers on inflammation or endothelial function ( p>0.1 for all ) . CONCLUSIONS RYGB causes substantial and sustained favorable effects on markers of inflammation and endothelial function .  Supervised physical training after RYGB did not cause additional improvements UNLABELLED To investigate whether interleukin-6 ( IL-6 ) , C-reactive protein ( CRP ) and tumor necrosis factor-alpha ( TNF-α ) protein levels predict all-cause mortality in older persons living in the community . DESIGN Prospect i ve cohort study . SETTING Data were from the Aging and Longevity Study in the Sirente Geographic Area , a prospect i ve cohort study . PARTICIPANTS Individuals aged 80 and older living in an Italian mountain community ( N = 362 ) . MEASUREMENTS Participants were classified according to the median value of the three inflammation markers ( IL-6 , 2.08 pg/mL ; TNF-α , 1.43 pg/mL ; CRP , 3.08 mg/L ) . A composite summary score of inflammation was also created . The main outcome was risk of death after 4 years of follow-up . RESULTS One hundred fifty deaths occurred during 4 years of follow-up . In the unadjusted model , high levels of each of the three markers were associated with greater mortality . After adjusting for potential confounders , high levels of IL-6 ( hazard ratio ( HR ) = 2.18 , 95 % confidence interval ( CI ) = 1.29 - 3.69 ) and CRP ( HR = 2.58 , 95 % CI = 1.52 - 4.40 ) were associated with a significantly greater risk of death , whereas the association between TNF-α protein levels and mortality was no longer significant ( HR = 1.26 , 95 % CI = 0.74 - 2.15 ) . The composite summary score of inflammation was strongly associated with mortality , with the highest risk estimated for individuals with all three inflammatory markers above the median . CONCLUSION Low levels of inflammatory markers are associated with better survival in older adults , independent of age and other clinical and functional variables Background Increased visceral adipose tissue is a risk factor for the metabolic complications associated with obesity and promotes a low- grade chronic inflammatory process . Resection of the great omentum in patients su bmi tted to a bariatric procedure has been proposed for the amelioration of metabolic alterations and the maximization of weight loss . The aim of the present study was to investigate the impact of omentectomy performed in patients with morbid obesity undergoing sleeve gastrectomy ( SG ) on metabolic profile , adipokine secretion , inflammatory status , and weight loss . Methods Thirty-one obese patients were r and omized into two groups : SG alone or with omentectomy . Adiponectin , omentin , interleukin-6 ( IL-6 ) , tumor necrosis factor-α ( TNF-α ) , high-sensitivity C-reactive protein ( hs-CRP ) , blood lipids , fasting glucose , insulin , and insulin resistance were measured before surgery and at 7 days , and 1 , 3 and 12 months after surgery . Results During the 1-year follow-up , body mass index ( BMI ) decreased markedly and comparably in both groups ( p < 0.001 ) . Insulin , IL-6 , and hs-CRP levels decreased significantly compared to baseline ( p < 0.05 ) in both groups with no significant difference between groups . Adiponectin and high-density lipoprotein cholesterol levels were significantly and similarly increased compared to baseline ( p < 0.001 ) in both groups . Omentin levels increased significantly ( p < 0.05 ) in the control group and decreased in the omentectomy group 1 year postoperatively . There was no significant change in TNF-α levels in either group . Conclusions The theoretical advantages of omentectomy in regard to weight loss and obesity-related abnormalities are not confirmed in this prospect i ve study . Furthermore , omentectomy does not induce important changes in the inflammatory status in patients undergoing SG BACKGROUND Bariatric surgery is an effective treatment for morbid obesity . Obesity and type 2 diabetes are associated with chronic inflammation . There is lack of data examining the effects of sleeve gastrectomy ( SG ) on inflammatory biomarkers . Our aim was to study the effects of SG on specific cytokines associated with obesity including interleukin-6 ( IL-6 ) , interleukin-10 ( IL-10 ) , leptin , adiponectin , and C-reactive protein ( CRP ) preoperatively , 1 and 6 months after surgery . METHODS A nonr and omized prospect i ve study comprising of 22 participants with impaired glucose homeostasis and type 2 diabetes undergoing SG ( body mass index 50.1 kg/m(2 ) , glycated hemoglobin [ HbA1c ] 53 mmol/mol ) .  Serial measurements of IL-6 , IL-10 , leptin , adiponectin , and CRP  were performed during oral glucose tolerance testing preoperatively , 1 and 6 months postoperatively . RESULTS We observed significant improvements at 1 and 6 months in leptin ( P≤.001 ) and CRP ( P = .003 ) after SG . We also observed a significant reduction in IL-6 at 6 months ( P = .001 ) . No statistically significant differences were observed for adiponectin and IL-10 . CONCLUSION This study is the first to examine the detailed changes in the inflammatory cytokines after SG . Our study shows significant improvements in the inflammatory biomarkers after SG in patients with impaired glucose homeostasis and type 2 diabetes Abstract This study evaluated the effects of 10-day broccoli ( 250 g/day ) intake on dietary markers and markers of inflammations in young male smokers . A dietary intervention study with a repeated measures crossover design was conducted . Circulating levels of carotenoids , folate , C-reactive protein ( CRP ) , tumor necrosis factor alpha ( TNF-α ) , interleukin 6 ( IL-6 ) , interleukin 6 receptor ( IL-6sR ) and adiponectin were measured . Broccoli intake significantly increased plasma levels of folate ( + 17 % ) and lutein ( + 39 % ) , while no significant effect was observed for TNF-α , IL-6 , IL-6sR or adiponectin . Plasma CRP decreased by 48 % ( post-hoc analysis , p < 0.05 ) following broccoli diet ; this result ed to be independent from the plasma variations in lutein and folate . An inverse correlation between lycopene , TNF-α and IL-6sR was observed at baseline . In conclusion , broccoli consumption may reduce CRP levels in smokers , consistent with epidemiologic observations that fruit and vegetable intake is associated with lower circulating CRP concentrations BACKGROUND This study sought to assess inflammation activation in the follow-up ( up to one month ) of  coronary bypass surgery performed both on- ( CABG ) and off-pump ( OPCAB ) . METHODS Thirty patients , c and i date s for coronary surgery , were r and omized to undergo CABG ( n = 16 ) or OPCAB ( n = 14 ) . Blood sample s were collected before the intervention , after protamine administration , and 4 , 8 , and 30 days after surgery . RESULTS Plasma tumor necrosis factor-alpha ( TNF-alpha ) and interleukin-6 ( IL-6 ) levels significantly increased with respect to baseline from protamine administration up to eight postoperative days , whereas high-sensitivity C-reactive protein ( hs-CRP ) and fibrinogen increased after surgery up to eight postoperative days in both groups . On the other h and , neutrophil elastase levels were higher than baseline from protamine administration up to four postoperative days in CABG , and at the time point eight days after surgery in OPCAB . The only significant differences between CABG and OPCAB in inflammatory markers occurred intraoperatively , after protamine administration , when TNF-alpha and elastase levels were higher in CABG , whereas no differences were detected between CABG and OPCAB at any postoperative time point . Postoperative increases in fibrinogen and hs-CRP were positively correlated with increases in IL-6 , but not with postoperative changes in TNF-alpha both in CABG and OPCAB . CONCLUSIONS After coronary bypass surgery , there is a protracted postoperative activation of inflammation persisting several days after surgery ; this postoperative activation is not affected by the surgical strategy ( on-pump or off-pump ) Insufficient vitamin D status has been linked to autoimmune diseases , cancer and metabolic disorders , like obesity and insulin resistance . In vitro and animal studies suggest that vitamin D may play a crucial role in immune activation and inflammation . The relation between vitamin D and pro-inflammatory cytokines is not completely established . Furthermore , it is not known if the effect of vitamin D on entities of metabolic syndrome is mediated through its effect on cytokines or other biomarkers . The objectives of this study were to investigate if there is a relationship between vitamin D status and such pro-inflammatory cytokines as tumor necrosis factor-alpha ( TNF-α ) , interleukin 6 ( IL-6 ) and high sensitive C-reactive protein ( hs-CRP ) in patients with overweigh and obesity . We also proposed that the intervention with high dose of cholecalciferol may have effect on the cytokine levels and result in corresponding changes in the measures of insulin resistance ( HOMA-IR and QUICKI ) . Serum levels of IL-6 , TNF-α and hs-CRP were measured in 332 overweight and obese subjects who completed a 1-year r and omised intervention with either 40,000 IU vitamin D ( cholecalciferol ) per week or 20,000 IU vitamin D per week  ,  or placebo .  We found significant associations between IL-6 , TNF-α , vitamin D and insulin resistance indices at baseline . One year intervention with vitamin D  decreased serum IL-6 levels ; however hs-CRP levels were significantly increased . Neither measures of insulin resistance , nor TNF-α were influenced by a 1-year vitamin D supplementation BACKGROUND Off-pump coronary artery bypass graft surgery ( OPCAB ) is still associated with a marked systemic inflammatory response . The aim of this study was to investigate whether pre-emptive , low dose of ketamine , which has been reported to have anti-inflammatory activity in on-pump coronary artery bypass surgery , could reduce inflammatory response in low-risk patients undergoing OPCAB . METHODS In this prospect i ve r and omized-controlled trial , 50 patients with stable angina and preserved myocardial function undergoing OPCAB were r and omly assigned to receive either 0.5 mg kg(-1 ) of ketamine ( Ketamine group , n=25 ) or normal saline ( Control group , n=25 ) during induction of anaesthesia . Inflammatory markers including C-reactive protein ( CRP ) , interleukin (IL)-6 , tumour necrosis factor-alpha ( TNF-alpha ) , and cardiac enzymes were measured previous to induction ( T1 ) , 4 h after surgery ( T2 ) , and the first and second days after the surgery ( T3 and T4 ) . RESULTS There were no significant intergroup differences in the serum concentrations of the CRP , IL-6 , and TNF-alpha and cardiac enzymes . Pro-inflammatory markers and cardiac enzymes , except TNF-alpha , were all increased after the surgery compared with baseline values in both groups . CONCLUSIONS Low-dose ketamine administered during anaesthesia induction did not exert any evident anti-inflammatory effect in terms of reducing the serum concentrations of pro-inflammatory markers in low-risk patients undergoing OPCAB OBJECTIVE This study aim ed to explore effects of adjunctive treatment with N-acetyl cysteine ( NAC ) on markers of inflammation and neurogenesis in bipolar depression . METHODS This is a secondary analysis of a placebo-controlled r and omised trial . Serum sample s were collected at baseline , week 8 , and week 32 of the open-label and maintenance phases of the clinical trial to determine changes in interleukin (IL)-6 , IL-8 , IL-10 , tumour necrosis factor-α ( TNF-α ) , C-reactive protein ( CRP ) and brain-derived neurotrophic factor ( BDNF ) following adjunctive NAC treatment , and to explore mediation and moderator effects of the listed markers . RESULTS Levels of brain-derived neurotrophic factor ( BDNF ) , tumour necrosis factor-α ( TNF-α ) , C-reactive protein ( CRP ) , interleukins ( IL ) -6 , 8 , or 10 were not significantly changed during the course of the trial or specifically in the open-label and maintenance phases . There were no mediation or moderation effects of the biological factors on the clinical parameters . CONCLUSION The results suggest that these particular biological parameters may not be directly involved in the therapeutic mechanism of action of adjunctive NAC in bipolar depression BACKGROUND Despite an extensive literature on the role of inflammation and depression , few studies have evaluated the association between inflammatory biomarkers and depression in a prospect i ve manner , and results are inconclusive . METHODS We conducted a prospect i ve analysis of blood levels of CRP , IL-6 and TNFα-R2 in 4756 women participating in the Nurses׳ Health Study who donated blood in 1990 and were depression-free up to 1996 . Participants were followed between 1996 and 2008 for reports of clinical diagnosis depression or antidepressant use . Additionally , we conducted cross-sectional analyses for CRP , IL-6 and TNFα-R2 and antidepressant use at time of blood draw . RESULTS After adjustment for body mass index , menopause status , use of anti-inflammatory drugs and other covariates , no significant associations between CRP , IL-6 and TNFα-R2 and incident depression were observed after a follow-up of 6 - 18 years . However , menopause status appears to modify the association between IL-6 and depression risk . In cross-sectional analyses , TNFα-R2 was associated with antidepressant use ( OR=1.96 , 95 % CI=1.23 - 3.13 , P-trend=0.001 ) , but no significant associations were found for CRP and IL-6 . LIMITATIONS Depression diagnosis was first assessed in 1996 , 6 years after blood draw . However the biomarkers have high within-person correlations with measurements 4 years apart . CONCLUSIONS Blood levels of CRP , IL-6 and TNFα-R2 were not associated with incident depression over a follow-up of 6 - 18 years . In cross-sectional analyses , antidepressant use may be associated with higher levels of TNFα-R2 but no associations with depression or antidepressant use were observed in the prospect i ve analysis High blood pressure ( HBP ) has been associated with elevated C-reactive protein ( CRP ) , a marker of chronic mild inflammation . However , the association between HBP and other inflammatory markers , particularly interleukin 6 ( IL-6 ) and tumour necrosis alpha ( TNF-α ) , has not been evaluated in well-controlled studies . We examined the cross-sectional relationship between IL-6 , TNF-α , and CRP and HBP in a r and om sample of 196 healthy subjects . All markers were measured in duplicate with high-sensitivity ELISA tests . Three blood pressure ( BP ) measurments were averaged for the analysis , and subjects with systolic BP ⩾140 and /or diastolic BP ⩾90 mmHg were considered hypertensive . Log binomial regression was used to estimate multivariate-adjusted prevalence ratios ( PR ) of HBP . Of the subjects , 40 % ( 79 ) were hypertensive ( mean age : 44 years ; range 30–64 ) . After adjustment for age , sex , body mass index , family history of HBP , and the level of the other inflammatory markers , subjects in the second ( PR : 3.10 , P=0.003 ) , third ( PR : 2.32 ; P=0.031 ) , and fourth quartiles ( PR : 2.30 ; P=0.036 ) of IL-6 were more than twice as likely to be hypertensive than those in the first quartile . Corresponding PR estimates for TNF-α levels were 1.41 ( P=0.014 ) for the second ; 1.59 ( P=0.001 ) for the third ; and 1.61 ( P=0.025 ) for the fourth quartile . The CRP – HBP association was not statistically significant . Our results suggest that TNF-α and IL-6 could be independent risk factors for HBP in apparently healthy subjects . Nevertheless , the temporal relationship between elevated inflammation markers and HBP should be ascertained in prospect i ve cohort studies Background :  Cardiac surgery with cardiopulmonary bypass ( CPB )  evokes a systemic inflammatory response involving the proinflammatory cytokines tumor necrosis factor‐α ( TNFα ) , interleukin (iL)‐1 , IL‐6 , IL‐8 and anti‐inflammatory cytokines such as IL‐10 . Like IL‐10 , opioids downregulate the immune responses in vivo and in vitro , including the activity of the cytokine‐producing monocytes and granulocytes . The proinflammatory cytokines are potent inducers of the hepatic acute‐phase protein synthesis . The aim of the present study was to investigate if choice of anaesthesia , based on high‐dose opioids ( fentanyl ) versus low‐dose opioids  influenced the release of IL‐6 , IL‐8 , and IL‐10 . Secondly , it was investigated whether serum amyloid P‐component ( SAP ) is an acute‐phase protein in man such as C‐reactive protein ( CRP ) , with which it is physically and structurally related n-3 fatty acids reduce the risk of cardiovascular disease via a number of possible mechanisms . Despite this , there has been concern that these fatty acids may increase lipid peroxidation . The data in vivo are inconclusive , due in part to limitations in the method ologies . In this regard , the measurement of F2-isoprostanes provides a reliable assessment of in vivo lipid peroxidation and oxidant stress . This study aim ed to assess the effects of supplementation with purified eicosapentaenoic acid ( EPA ) or docosahexaenoic acid ( DHA ) , the two major n-3 fatty acids , on urinary F2-isoprostanes and markers of inflammation , in type 2 diabetic patients . In a double-blind , placebo controlled trial of parallel design , 59 nonsmoking , treated-hypertensive , type 2 diabetic subjects , were r and omized to 4 g daily of purified EPA , DHA , or olive oil for 6 weeks , while maintaining their usual diet . F2-isoprostanes , measured using gas chromatography-mass spectrometry in 24 h urines and C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) and tumor necrosis factor-alpha ( TNF-alpha ) , were measured before and after intervention . Thirty-nine men and 12 women aged 61.2 + /- 1.2 years , with body mass index ( BMI ) , 29.5 + /- 0.5 kg/m2 ; 24 h blood pressure , 138/73 mmHg ; HbA1c , 7.3 + /- 0.1 % and fasting glucose , 7.9 + /- 0.2 mmol/l completed the intervention .  Baseline urinary F2-isoprostanes were positively associated with HbA1c ( p=.011 ) and fasting glucose ( p=.032 ) . Relative to the olive oil group , postintervention urinary F2-isoprostanes were decreased 19 % by EPA ( p=.017 ) and 20 % by DHA ( p=.014 ) . There were no significant changes in CRP , IL-6 , and TNF-alpha following EPA or DHA supplementation . In regression analysis , Delta F2-isoprostanes were positively associated with Delta HbA1c ( p=.007 ) independent of treatment group ; and with Delta TNF-alpha ( p=.034 ) independent of age , gender , BMI , and treatment group . There were no associations with Delta CRP or Delta IL-6 . This study is the first report demonstrating that either EPA or DHA reduce in vivo oxidant stress without changing markers of inflammation , in treated hypertensive , type 2 diabetic subjects The pathology of type 2 diabetes mellitus ( DM ) often is associated with underlying states of conditioned zinc deficiency and chronic inflammation . Zinc and omega-3 polyunsaturated fatty acids each exhibit anti-inflammatory effects and may be of therapeutic benefit in the disease . The present r and omized , double-blind , placebo-controlled , 12-week trial was design ed to investigate the effects of zinc ( 40 mg/day ) and α-linolenic acid ( ALA ; 2 g/day flaxseed oil ) supplementation on markers of inflammation [ interleukin (IL)-1β , IL-6 , tumor necrosis factor (TNF)-α , C-reactive protein ( CRP ) ] and zinc transporter and metallothionein gene expression in 48 postmenopausal women with type 2 DM . No significant effects of  zinc or ALA supplementation were observed on inflammatory marker concentrations or fold change in zinc transporter and metallothionein gene expression . Significant increases in plasma zinc concentrations were observed over time in the groups supplemented with zinc alone or combined with ALA ( P=.007 and P=.009 , respectively ) . An impact of zinc treatment on zinc transporter gene expression was found ; ZnT5 was positively correlated with Zip3 mRNA ( P<.001 ) only in participants receiving zinc , while zinc supplementation abolished the relationship between ZnT5 and Zip10 . IL-6 predicted the expression levels and CRP predicted the fold change of the ZnT5 , ZnT7 , Zip1 , Zip7 and Zip10 mRNA cluster ( P<.001 and P=.031 , respectively ) . Fold change in the expression of metallothionein mRNA was predicted by TNF-α ( P=.022 ) . Associations among inflammatory cytokines and zinc transporter and metallothionein gene expression support an interrelationship between zinc homeostasis and inflammation in type 2 DM BACKGROUND Blood lipids and inflammatory markers levels have been associated with the development and progression of atherosclerosis . As the association of inflammatory markers with plasma fatty acids has not been extensively evaluated and understood , we sought to investigate the associations between dietary and plasma fatty acids with various inflammation and coagulation markers . METHODS High sensitivity C-reactive protein ( hsCRP ) , interleukin-6 ( IL-6 ) , tumor necrosis factor-alpha ( TNF-alpha ) , fibrinogen , and homocysteine were measured in serum of 374 free-living , healthy men and women , r and omly selected from the ATTICA 's study data base .  Total plasma fatty acids  were determined by gas chromatography . Dietary fatty acids  were assessed through a semi-quantitative FFQ . RESULTS Multi-adjusted regression analyses revealed that plasma n-3 fatty acids were inversely associated with CRP , IL-6 and TNF-alpha ; plasma n-6 fatty acids were inversely associated with CRP , IL-6 and fibrinogen ; monounsaturated fatty acids were inversely associated with CRP and IL-6 ( all p-values<0.05 ) . Interestingly , the n-6/n-3 ratios exhibited the strongest positive correlations with all the markers studied . No associations were observed between dietary fatty acids and the investigated markers . CONCLUSIONS Measurements of total plasma fatty acids could provide insights into the relationships between diet and atherosclerotic disease . Moreover , the n-6/n-3 ratio may constitute a predictor of low- grade inflammation and coagulation Background : Human adipose tissue expresses and releases proinflammatory cytokines and these measures of chronic inflammation have recently been associated with obesity . Hypothesis : To test whether the proinflammatory state is reversible in subjects undergoing weight loss by surgical measures .Subjects and Methods : Twenty morbidly obese women participated in this prospect i ve study . Subjects were examined for fat mass , high-sensitive C-reactive protein ( hs-CRP ) , interleukin 6 ( IL-6 ) and tumor necrosis factor-alpha ( TNF-α ) before and 1 y after Swedish adjustable gastric b and ing . Results : Anthropometric measures displayed a significant reduction of the body mass index ( BMI ) from 41.6±5.4 to 30.8±6.1 kg/m2 and the fat mass from 53.9±10.3 to 29.8±12.1 kg ( mean±s.d . ) . Hs-CRP levels decreased significantly from 1.33±1.21 mg/dl in pre-gastric b and ing subjects to 0.40±0.61 mg/dl in post-gastric b and ing subjects , respectively . IL-6 and TNF-α levels did not differ significantly between pre- and post-gastric b and ing subjects . Conclusions : We speculate that in these patients the marked reduction in C-reactive protein might be beneficial in reducing their cardiovascular risk and is not solely mediated by IL-6 and TNF-α We conducted a prospect i ve , nested , case-control study of inflammatory markers as predictors of  type 2 diabetes among 32,826 women who provided blood sample s in 1989 through 1990 in the Nurses ' Health Study . Among women free of diabetes , cardiovascular disease , or cancer at baseline , 737 had developed diabetes by 2000 . Control women ( n = 785 ) were selected matched on age , fasting status , race , and BMI for cases in the top BMI decile . Baseline levels of tumor necrosis factor (TNF)-alpha receptor 2 , interleukin (IL)-6 , and C-reactive protein ( CRP ) were significantly higher among case than control subjects ( all P < /= 0.001 ) . After adjusting for BMI and other lifestyle factors , all three biomarkers significantly predicted diabetes risk ; the odds ratios ( ORs ) comparing extreme quintiles were 1.64 ( 95 % CI 1.10 - 2.45 ) for TNF-alphaR2 , 1.91 ( 1.27 - 2.86 ) for IL-6 , and 4.36 ( 2.80 - 6.80 ) for CRP ( P for trend < 0.001 for all biomarkers ) . In a multivariate model simultaneously including the three biomarkers , only CRP levels were significantly associated with risk of diabetes ( OR comparing extreme quintiles of CRP = 3.99 , P for trend < 0.001 ) . These data support the role of inflammation in the pathogenesis of type 2 diabetes . Elevated CRP levels are a strong independent predictor of type 2 diabetes and may mediate associations of TNF-alphaR2 and IL-6 with type 2 diabetes OBJECTIVE Abdominal obesity is associated with a fasting proinflammatory condition . However , not much is known of the potential variations in circulating inflammatory markers after food intake . The purpose of the present study was to examine postpr and ial changes in plasma tumor necrosis factor (TNF)-alpha , interleukin (IL)-6 , and C-reactive protein ( CRP ) concentrations in men and their potential associations with fat distribution and metabolic profile variables . RESEARCH METHODS AND PROCEDURES Thirty-eight men were given a high-fat meal in the morning after an overnight fast , and TNF-alpha , IL-6 , and CRP levels were measured in plasma at 0 , 4 , and 8 hours after the meal . Physical and metabolic profiles were also assessed for each participant . RESULTS We observed a substantial increase in circulating IL-6 levels ( p < 0.0001 ) after the meal . Although postpr and ial variations in circulating TNF-alpha levels across time failed to reach statistical significance ( p = 0.02 ) , we noted a significant decrease in plasma TNF-alpha concentrations 4 hours ( -10 % , p < 0.001 vs. 0 hours ) after food intake . Plasma CRP levels were not affected by the fat load . We also noted that insulin-sensitive individuals displayed a less pronounced inflammatory response after food intake than insulin-resistant subjects . DISCUSSION Results of the present study show that consumption of a high-fat meal leads to an increase in plasma IL-6 concentrations and transient decrease in circulating TNF-alpha levels in overweight men . Our results suggest a possible role of insulin resistance in the modulation of the postpr and ial inflammatory response , which could , in turn , contribute to worsen the state of insulin resistance Coronary endothelial function is impaired in hypertension ; however , the severity of this impairment varies among patients . We aim ed to identify the predictors of coronary endothelial dysfunction among clinical variables related to hypertension and atherosclerosis . Twenty-seven untreated , uncomplicated essential hypertensive patients and 10 age-matched healthy controls were studied prospect ively . Myocardial blood flow ( MBF ) was measured by using 15O-water positron emission tomography ( PET ) at rest and during a cold pressor test ( CPT ) .  Coronary vascular resistance ( CVR ) during CPT was used as a marker of coronary endothelial function . Serum low density lipoprotein ( LDL ) cholesterol , high density lipoprotein ( HDL ) cholesterol , triglycerides , malondialdehyde-LDL , homeostasis model assessment , high-sensitivity C-reactive protein ( hs-CRP ) , and plasma interleukin-6 ( IL-6 ) and tumor necrosis factor (TNF)-α were also measured . CVR during CPT  was significantly higher in hypertensive patients than in healthy controls ( 114±26 vs. 94±12 mmHg/[mL/g/min ] ; p<0.05 ) . By univariate analysis , CVR during CPT  was correlated with LDL cholesterol ( r=0.38 , p<0.05 ) , IL-6 ( r=0.46 , p<0.02 ) , and TNF-α ( r=0.39 , p<0.05 ) in hypertensive patients . By multivariate analysis , IL-6 and TNF-α were significant independent predictors of CVR during CPT . Elevated plasma IL-6 and TNF-α levels were independent predictors of coronary endothelial dysfunction in hypertensive patients . These results suggest that plasma IL-6 and TNF-α might be useful for identifying the high risk subgroup of hypertensive patients with coronary endothelial dysfunction and provide an important clue to link systemic inflammation to the development of coronary atherosclerosis A r and omized , crossover study compared the effects of atorvastatin , gemfibrozil and their combination on inflammatory markers in type 2 diabetes .  C-reactive protein ( CRP ) , lipoprotein-associated phospholipase A2 ( Lp-PLA2 ) , secretory phospholipase A2 ( sPLA2 ) , interleukin 8 ( IL8 ) , monocyte chemotactic protein 1 ( MCP1 ) and tumor necrosis factor α ( TNFα ) were measured . Both lipid-lowering drugs had positive , complementary and additive effects on inflammatory markers , which were closely related to baseline inflammatory status AIM To investigate the effects of corticosteroids on the reduction of inflammatory response after cardiopulmonary bypass . METHODS Twenty patients undergoing elective coronary revascularization were r and omized into two groups , which both underwent coronary artery bypass surgery with the aid of normothermic cardiopulmonary bypass . One group received a single dose of methylprednisolone prior to normothermic cardiopulmonary bypass , whereas no steroid treatment was given to other group of patients . The two groups were comparable with respect to preoperative demographic data . Serum sample s from all patients were drawn preoperatively and 3 , 6 , and 24 hours after the surgical procedure . The serum concentrations of tumor necrosis factor alpha ( TNF-alpha ) , interleukin-1beta ( IL-1beta ) , interleukin-6 ( IL-6 ) , interleukin-8 ( IL-8 ) , as well as the white blood cell count were measured . Serum C-reactive protein concentrations ( CRP ) were determined preoperatively and 72 hours postoperatively . St and ard hemodynamic measurements for both groups were collected and analyzed . RESULTS We did not find any increase in the postoperative concentrations of TNF-alpha and IL-1beta in either group . The concentrations of IL-6 and IL-8 increased significantly in both groups , from immeasurable concentrations preoperatively to as high as 496 pg/mL for IL-6 and 128 pg/mL for IL-8 three hours after surgery . However , the observed increase was significantly smaller in the group of patients receiving methylprednisolone . CONCLUSION It seems that the administration of corticosteroids prior to the initiation of cardiopulmonary bypass may alleviate the intensity of the inflammatory response , as evidence d by reduced increase in inflammatory mediators Background Obesity is considered a low- grade chronic inflammatory condition as reflected by increased C-reactive protein ( CRP ) levels . Inflammation is emerging as a predictor of cardiovascular disease and it may be a precursor of the metabolic syndrome . Bariatric surgery is commonly performed as a treatment for morbid obesity offering significant reductions in premature myocardial infa rct ion . Laparoscopic sleeve gastrectomy ( LSG ) is a relatively new bariatric procedure that is currently used as a definitive procedure for weight loss . The aim of this study is to assess the impact of sleeve gastrectomy on CRP levels . Methods This study is part of an ongoing , prospect i ve , cohort study to evaluate LSG impact on iron indices . CRP levels were compared preoperatively and 6 months after surgery . Similarly , demographics including body mass index and excess weight were also compared at these same study points . Data were analyzed using Student paired t test and Pearson product moment correlation analysis . Results Twenty-nine morbidly obese patients were included . There was significant decrease in body mass index ( BMI ) between the preoperative and 6-month period ( 50.9 ± 13.2 and 35.1 ± 6.85 , respectively ; P < 0.001 ) . Also CRP levels were statistically significantly lower at 6 months after surgery ( preoperative 12.3 ± 7.53 mg/L and postoperative 5.6 ± 4.2 mg/L. P < 0.0001 ) . The significant weight loss as reflected by change in BMI was correlated with the difference between preoperative and postoperative CRP levels . Conclusions Massive weight loss in morbidly obese patients induced by LSG causes a significant decrease in CRP levels , which could reduce the risk of cardiovascular diseases in these patients OBJECTIVE Stress-related physiological activation may last longer for those who ruminate , or dwell , on past stressors . Correlational and quasi-experimental research has linked rumination to immune activity and elevated cortisol . This study 's aim was to experimentally test whether rumination ( relative to distraction ) can sustain stress-induced increases in inflammation and cortisol . Concentrations of poststressor cortisol and inflammatory markers were hypothesized to be greater for those who ruminated compared with those who were distracted . METHOD Thirty-four healthy young women completed a laboratory speech stressor  and were then r and omly assigned to either ruminate on the stressor or engage in distraction for 5 minutes . Salivary cortisol and circulating plasma concentrations of C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) , and tumor necrosis factor-alpha ( TNF-α ) were assessed throughout the 2-hr visit . RESULTS As predicted , CRP and cortisol responses differed for the rumination and distraction groups . In the distraction group , participants ' CRP concentrations increased poststressor and then returned to prestressor levels by the end of the visit . In contrast , participants in the rumination condition demonstrated increases in CRP that did not return to prestressor levels by the end of the visit . Similarly , poststressor cortisol was higher for those who ruminated compared with those who were distracted . Plasma IL-6 and TNF-α concentrations increased over the visit , but did not differ by experimental group . CONCLUSIONS RESULTS suggest that ruminating on stressors may sustain CRP and cortisol responses , whereas distraction may diminish them . Findings have implication s for underst and ing potential risk and protective factors for stress-related activation INTRODUCTION Consumption of omega-3 fatty acids can alter the inflammatory response in diabetic patients . This study aim ed to determine the effects of omega-3 fatty acid supplementation on the serum levels of C-reactive protein ( CRP ) , interleukin (IL)-2 and tumour necrosis factor-alpha ( TNF-α ) in type 2 diabetes mellitus patients . METHODS A r and omised , double-blind , placebo-controlled clinical trial was conducted on 84 subjects aged 45 - 85 years with at least a two-year history of type 2 diabetes mellitus . Participants were r and omly assigned to the treatment or control group . Each subject in the treatment group received three omega-3 capsules per day ( eicosapentaenoic acid 1,548 mg ; docosahexaenoic acid 828 mg ; other omega-3 fatty acids 338 mg ) , while each subject in the control group received three placebo capsules ( sunflower oil 2,100 mg ) for a period of eight weeks . At the beginning of the study and post intervention , fasting blood sample s were taken and serum concentrations of IL-2 , TNF-α and CRP were assessed and compared . RESULTS Serum IL-2 and TNF-α levels were significantly reduced in the treatment group compared to the controls ( p < 0.01 ) . There was no significant change in serum CRP levels . CONCLUSION Short-term omega-3 fatty acid supplementation ( 3 g/day for eight weeks ) can decrease the serum levels of TNF-α and IL-2 in diabetic patients , with no change in CRP levels . Consumption of omega-3 fatty acid supplements is highly recommended to alleviate inflammation caused by type 2 diabetes mellitus OBJECTIVE Inflammation mediators have been recognized as risk factors for the pathogenesis of coronary artery disease ( CAD ) . The purpose of this study was to investigate the effect of L-carnitine supplementation ( LC , 1000 mg/d ) on inflammation markers in patients with CAD . METHODS We enrolled 47 patients with CAD in the study . The patients with CAD were identified by cardiac catheterization as having < 50 % stenosis of one major coronary artery . The patients were r and omly assigned to the placebo ( n = 24 ) and LC ( n = 23 ) groups and the intervention was administered for 12 wk . The levels of LC , antioxidant status ( malondialdehyde and antioxidant enzymes activities ) , and inflammation markers ( C-reactive protein [ CRP ] , interleukin [IL]-6 , and tumor necrosis factor [TNF]-α ) were measured . RESULTS Thirty-nine participants completed the study ( 19 placebo ; 20 LC ) . After LC supplementation , the levels of inflammation markers were significantly reduced compared with the baseline ( CRP , P < 0.01 ; IL-6 , P = 0.03 ; TNF-α , P = 0.07 ) and those in the placebo group ( CRP , P < 0.05 ; IL-6 , P = 0.04 ; TNF-α , P = 0.03 ) . The levels of inflammation markers were significantly negatively correlated with the levels of LC and antioxidant enzymes activities ( P < 0.05 ) . CONCLUSIONS We suggest that LC supplementation , due to its antioxidant effects , may have potential utility to reduce inflammation in CAD The fatigue induced by marathon races was observed in terms of inflammatory and immunological outcomes . Neutrophil survival and activation are essential for inflammation resolution and contributes directly to the pathogenesis of many infectious and inflammatory conditions . The aim of this study was to investigate the effect of marathon races on surface molecules related to neutrophil adhesion and extrinsic apoptosis pathway and its association with inflammatory markers . We evaluated 23 trained male runners at the São Paulo International Marathon 2013 . The following components were measured : hematological and inflammatory mediators , muscle damage markers , and neutrophil function . The marathon race induced an increased leukocyte and neutrophil counts ; creatine kinase ( CK ) , lactate dehydrogenase ( LDH ) , CK-MB , interleukin (IL)-6 , IL-10 , and IL-8 levels . C-reactive protein ( CRP ) , IL-12 , and tumor necrosis factor (TNF)-α plasma concentrations were significantly higher 24 h and 72 h after the marathon race . Hemoglobin and hematocrit levels decreased 72 h after the marathon race . We also observed an increased intercellular adhesion molecule-1 ( ICAM-1 ) expression and decreasedTNF receptor-1 ( TNFR1 ) expression immediately after and 24 h after the marathon race . We observed an increased DNA fragmentation and L-selectin and Fas receptor expressions in the recovery period , indicating a possible slow rolling phase and delayed neutrophil activation and apoptosis . Marathon racing affects neutrophils adhesion and survival in the course of inflammation , supporting the “ open-window ” post-exercise hypothesis The aim of this study was to evaluate the effect of an oral glucose tolerance test ( OGTT ) on the level of endothelial dysfunction and vascular inflammation markers in healthy subjects ( H ) and diabetic overweight patients ( D ) . We enrolled 256 healthy subjects and 274 type 2 diabetic patients . We evaluated blood glucose ( BG ) , soluble intercellular adhesion molecule-1 ( sICAM-1 ) , interleukin-6 ( IL-6 ) , high-sensitivity C reactive protein ( hsCRP ) , soluble vascular cell adhesion molecule-1 ( sVCAM-1 ) , soluble E-selectin ( sE-selectin ) , and tumor necrosis factor-alpha ( TNF-alpha )  at baseline and after OGTT . We observed that BG , sICAM-1 , IL-6 , hs-CRP , sVCAM-1 , sE-selectin , and TNF-alpha values were higher in D group than in H group . In a large sample of adult healthy subjects and type 2 diabetics we observed that both answer to an OGTT with a significant increase in biomarkers of systemic low- grade inflammation and endothelial dysfunction such as hsCRP , IL-6 , TNF-alpha , sICAM-1 , sVCAM-1 , and sE-selectin . Type 2 diabetics experienced , however , a more significant increase in TNF-alpha , and sE-selectin OBJECTIVES To examine markers of inflammation in 9- and 15-year-olds with high waist circumference and compare these with controls , and to examine the relationships between inflammatory markers and cardiovascular disease ( CVD ) risk factors . METHODS Cross-sectional analysis of data from 2 299 Norwegian 9- and 15-year-olds participating in the " Physical activity among Norwegian Children Study " . In each sex and age group , the 10 participants with the highest waist circumference ( HW ) were selected ( n=40 ) for analyses , and a r and om sample of 40 participants within the same groups were included as controls . Inflammatory markers included C-reactive protein ( CRP ) , leptin , adiponectin , plasminogen activator inhibitor-1 ( PAI-1 ) , tumor necrosis factor-alpha ( TNF-alpha ) , hepatocyte growth factor ( HGF ) , resistin and interleukin-6 ( IL-6 ) . The CVD risk factors included blood pressure , glucose , insulin , triglycerides and high density lipoprotein cholesterol . RESULTS HW participants had elevated levels of CRP ( mean difference 1.50 mg/l ; 95 % confidence interval [ CI ] 0.33 to 2.66 ) , PAI-1 ( mean difference 13.3 ng/ml ; 95 % CI 4.1 to 22.5 ) and HGF ( mean difference 0.29 ng/ml ; 95 % CI 0.07 to 0.51 ) compared with controls . All CVD risk factors differed between the HW group and controls . The CVD risk factors were not associated with TNFalpha or IL-6 , but CRP , HGF and PAI-1 were related to the metabolic risk score . CONCLUSIONS Low grade systemic inflammation is already present in youth with high waist circumference . CRP , HGF and PAI-1 may be related to the adverse overall metabolic risk profile observed in these children and adolescents OBJECTIVE Treatment-resistant depression has recently emerged as a marker of increased risk for morbidity and mortality in patients with coronary heart disease ( CHD ) . Studies in depressed patients without CHD suggest that elevated markers of inflammation predict poor response to treatment . This may help to explain the increased risk of cardiac events associated with depression . We therefore studied the relationship between pretreatment markers of inflammation and treatment response in patients with CHD and major depression . METHODS This was a planned , secondary analysis of a clinical trial in which 122 patients with CHD and comorbid major depression were r and omly assigned to 50 mg of sertraline plus 2 g/day omega-3 fatty acids or to 50 mg of sertraline plus 2 g/day corn oil placebo capsules for ten weeks . Depressive symptoms were assessed with the Beck Depression Inventory-II ( BDI-II ) . Blood sample s were collected at baseline to determine levels of high-sensitivity C-reactive protein ( hs-CRP ) , interleukin-6 ( IL-6 ) , and tumor necrosis factor alpha ( TNF-α ) . The primary outcome was the post-treatment BDI-II depression score . RESULTS Baseline levels of hs-CRP , IL-6 , and TNF-α were not associated with the 10-week post-treatment depression score ( P=.89 , P=.88 , and P=.31 , respectively ) . Treatment responders ( > 50 % reduction from baseline BDI-II score ) did not differ from non-responders in either baseline hs-CRP , IL-6 , or TNF-α ( P=.83 , P=.93 , and P=.24 , respectively ) . Similarly , depression remitters ( BDI-II ≤8 at post-treatment ) did not differ from non-remitters on the three baseline inflammation markers . CONCLUSION These findings do not support the hypothesis that elevated baseline inflammatory markers predict poor response to sertraline in patients with CHD and major depression . The explanation for the increased risk of cardiac events associated with poor response to depression treatment remains unclear BACKGROUND Chronic low- grade inflammation may contribute to the increased risk of atherosclerosis in visceral obesity .  Statin and fish oil have been reported to have antiinflammatory effects . We studied whether dyslipidemic , obese individuals have increased plasma high-sensitivity C-reactive protein ( hs-CRP ) concentrations and whether treatment with atorvastatin and fish oil lowered plasma hs-CRP concentrations . METHODS We compared plasma hs-CRP , interleukin-6 ( IL-6 ) , and tumor necrosis factor-alpha ( TNF-alpha ) concentrations in 48 obese individuals with the concentrations in 10 lean normolipidemic men . The obese individuals were then r and omized to treatment with atorvastatin ( 40 mg/day ) , fish oil ( 4 g/day ) , atorvastatin plus fish oil , or matching placebo for 6 weeks . RESULTS Compared with controls , obese individuals had increased hs-CRP [ geometric mean , 2.19 mg/L ( 95 % confidence interval , 2.15 - 3.15 mg/L ) vs 0.49 mg/L ( 0.30- 0.93 mg/L ) ; P < 0.001 ] and IL-6 [ 351 pg/L ( 318 - 449 pg/L ) vs 251 pg/L ( 211 - 305 pg/L ) ; P < 0.01 ] . Atorvastatin treatment had a significant main effect of decreasing plasma hs-CRP ( -0.87 mg/L ; 95 % confidence interval , -0.10 to -1.60 mg/L ; P < 0.01 ) and IL-6 ( -70 pg/L ; 10 to -140 pg/L ; P < 0.01 ) , but this was not seen with fish oil . The reductions in hs-CRP with atorvastatin were not significantly correlated to changes in plasma lipids , IL-6 , insulin resistance , or cholesterogenesis . Plasma TNF-alpha concentrations in obese individuals , however , were neither statistically different from concentrations in the lean controls nor altered with atorvastatin or fish oil treatment . CONCLUSIONS This study shows that visceral obesity is associated with increased plasma hs-CRP and IL-6 and , hence , a low- grade chronic inflammatory state and that treatment with atorvastatin or atorvastatin with fish oil , but not fish oil alone , reverses this abnormality Objectives Complex regional pain syndrome type 1 ( CRPS 1 ) is a disorder that can affect an extremity after minor trauma or surgery . The pathogenesis of this syndrome is unclear . It has clinical signs of severe local inflammation as a result of an exaggerated inflammatory response , but neurogenic dysregulation also may contribute to it . Methods For further insights into the pathogenesis of CRPS 1 , the authors investigated inflammatory and neurogenic mediators — C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) , interleukin-8 ( IL-8 ) , soluble tumor necrosis factor receptor I/II ( sTNFR I/II ) ,  sE-selectin , sL-selectin , sP-selectin , substance P , neuropeptide Y , and calcitonin gene-related peptide — in  venous blood  from both the healthy arm and the arm with acute CRPS I from 25 patients and from 30 healthy volunteers . Results Levels of IL-8 and sTNFR I/II were significantly elevated in patients , whereas all soluble forms of selectins were significantly suppressed . There was no significant difference in white blood cell count ( WBC ) , CRP , and IL-6 . Substance P was significantly elevated in patients . The other two neuropeptides were unchanged . None of the parameters studied showed any differences between the CRPS I-affected arm and the normal arm . Conclusions Elevated IL-8 and sTNFR I/II levels indicate an association between CRPS I and an inflammatory process . Normal WBC , CRP , and IL-6 give evidence for localized inflammation . The hypothesis of neurogenic-induced inflammation mediated by neuropeptides is supported by elevated substance P levels Pulmonary problems are among the most frequent chronic complications of sulfur mustard ( SM ) intoxication and are often accompanied by deregulated production of pro-inflammatory cytokines . Curcuminoids , comprising curcumin , demethoxycurcumin and bisdemethoxycurcumin , are phytochemicals with remarkable anti-inflammatory properties that are derived from dried rhizomes of the plant Curcuma longa L. ( turmeric ) . The present pilot study aim ed to investigate the clinical effects of supplementation with curcuminoids on markers of pulmonary function and systemic inflammation in SM-intoxicated subjects . In a r and omized double-blind placebo-controlled trial , 89 male subjects who were suffering from chronic SM-induced pulmonary complications were recruited and assigned to either curcuminoids ( 500 mg TID per oral ; n=45 ) or placebo ( n=44 ) for a period of 4 weeks . Efficacy measures were changes in the spirometric parameters ( FVC , FEV1 , FEV1/FVC ) and serum levels of inflammatory mediators including interleukins 6 ( IL-6 ) and 8 ( IL-8 ) , tumor necrosis factor-α ( TNFα ) , transforming growth factor-β ( TGFβ ) , high-sensitivity C-reactive protein ( hs-CRP ) , calcitonin gene related peptide ( CGRP ) , substance P and monocyte chemotactic protein-1 ( MCP-1 ) . 78 subjects completed the trial .  Although FEV1 and FVC remained comparable between the groups , there was a greater effect of curcuminoids vs. placebo in improving FEV1/FVC ( p=0.002 ) . Curcuminoids were also significantly more efficacious compared to placebo in modulating all assessed inflammatory mediators : IL-6 ( p<0.001 ) , IL-8 ( p=0.035 ) , TNFα ( p<0.001 ) , TGFβ ( p<0.001 ) , substance P ( p=0.016 ) , hs-CRP ( p<0.001 ) , CGRP ( p<0.001 ) and MCP-1 ( p<0.001 ) . Curcuminoids  were safe and well-tolerated throughout the trial . Short-term adjunctive therapy with curcuminoids  can suppress systemic inflammation in patients suffering from SM-induced chronic pulmonary complications The objectives of the present investigation was to analyze the effect of two different recovery modalities on classical markers of exercise-induced muscle damage ( EIMD ) and inflammation obtained after a simulated trail running race . Endurance trained males ( n = 11 ) completed two experimental trials separated by 1 month in a r and omized crossover design ; one trial involved passive recovery ( PAS ) , the other a specific whole body cryotherapy ( WBC ) for 96 h post-exercise ( repeated each day ) . For each trial , subjects performed a 48 min running treadmill exercise followed by PAS or WBC .  The Interleukin ( IL ) -1 ( IL-1 ) , IL-6 , IL-10 , tumor necrosis factor alpha ( TNF-α ) , protein C-reactive ( CRP ) and white blood cells count were measured at rest , immediately post-exercise , and at 24 , 48 , 72 , 96 h in post-exercise recovery . A significant time effect was observed to characterize an inflammatory state ( Pre vs. Post ) following the exercise bout in all conditions ( p<0.05 ) . Indeed , IL-1β ( Post 1 h ) and CRP ( Post 24 h ) levels decreased and IL-1ra ( Post 1 h ) increased  following WBC when compared to PAS .  In WBC condition ( p<0.05 ) , TNF-α , IL-10 and IL-6 remain unchanged compared to PAS condition . Overall , the results indicated that the WBC  was effective in reducing the inflammatory process . These results may be explained by vasoconstriction at muscular level , and both the decrease in cytokines activity pro-inflammatory , and increase in cytokines anti-inflammatory Abstract Grape seed oil ( GSO ) is reported to improve oxidative stress and lipid profile . However , the ameliorating effect of GSO on inflammation and insulin resistance has not being noticed so far . We aim ed to examine the effects of GSO consumption on inflammation and insulin resistance in overweight or obese females . The subjects ( n = 44 ) were r and omly assigned into intervention group as “ GSO ” ( consuming 15 % of energy from GSO ) and control group as sunflower oil “ SFO ” ( consuming 15 % of energy from SFO ) through a weight loss diet for 8 weeks . Anthropometric measurements , dietary recall and fasting serum glucose , insulin , high sensitive C-reactive protein ( hs-CRP ) and tumor necrosis factor-alpha ( TNF-α ) were assessed before and after the intervention . Homeostatic model assessment of insulin resistance ( HOMA-IR ) scores , hs-CRP and TNF-α decreased in the GSO group . The hs-CRP was lower in GSO than the SFO group ( p < 0.03 ) . GSO consumption seems to improve inflammatory condition and insulin resistance in overweight/obese women Purpose This study was design ed to investigate the effects of omega-3 fatty acids on depression and chronic inflammation in hemodialysis patients . Method Fifty-four maintenance hemodialysis patients were r and omized to ingest two omega-3 ( each containing 180 mg eicosapentaenoic acid and 120 mg docosahexaenoic acid ) or placebo capsules , three times daily for 4 months . Main outcome measures : Beck Depression Inventory ( BDI ) score and serum levels of C-reactive protein ( CRP ) , interleukin (IL)-6 , IL-10 , tumor necrosis factor (TNF)-α , ferritin , intact parathyroid hormone ( iPTH ) , and ratios of IL-10 to IL-6 and IL-10 to TNF-α were measured at baseline and at the end of the study . Results Omega-3 supplement  lowered BDI score significantly after 4 months of intervention . Among pro- and anti-inflammatory mediators , only serum ferritin level and IL-10 to IL-6 ratio showed significant changes in favor of omega-3 supplement during the study . In linear regression model adjusted for baseline values , omega-3 treatment was a significant predictor of reduced serum CRP , ferritin , and iPTH levels , and increased IL-10 to IL-6 ratio . No significant association was found between the anti-inflammatory and anti-depressant effects  of omega-3 supplement . Conclusions Supplemental use of omega-3 fatty acids decreases depressive symptoms in hemodialysis patients apart from their anti-inflammatory effects BACKGROUND Inflammation and oxidative stress are associated with atrial fibrillation ( AF ) .  Statins have antioxidant and anti-inflammatory properties . We tested if atorvastatin reduced AF recurrence after DC cardioversion ( CV ) by modifying systemic oxidative stress and inflammation ( NCT00252967 ) . METHODS AND RESULTS In a r and omized , double-blinded , placebo-controlled trial , patients with atrial fibrillation/flutter ( AF ) were r and omized to receive either  atorvastatin 80 mg ( n = 33 )  or placebo ( n = 31 ) before CV . Treatment was continued for 12 months or until AF recurred . Serum oxidative stress markers ( ratios of oxidized to reduced glutathione and cysteine , derivatives of reactive oxygen species , isoprostanes ) and inflammatory markers ( high-sensitivity C- reactive protein [ hs-CRP ] , interleukin-6 [ IL-6 ] , interleukin-1β[IL-1β ] , tumor necrosis factor alpha [ TNFα ] ) were measured at baseline and on follow-up . AF recurred in 22 ( 66.7 % ) of atorvastatin and 26 ( 83.9 % ) of placebo group ( P = 0.2 ) . The adjusted hazard ratio of having recurrence on atorvastatin versus on placebo was 0.99 ( 95 % CI : 0.98 - 1.01 , P = 0.3 ) . There was no significant difference in the time to recurrence using Kaplan-Meier survival estimates ( median [ IR ] : 29 [ 2 - 145 ] days versus 22 [ 7 - 70 ] days , P = 0.9 ) . Although no significant effect was seen on oxidative stress , 2 of 4 inflammatory markers , IL-6 ( adjusted OR : 0.59 , 95 % CI : 0.35 - 0.97 , P = 0.04 ) and hs-CRP ( adjusted OR : 0.59 , 95 % CI : 0.37 - 0.95 , P = 0.03 ) were significantly lowered with atorvastatin  . Cholesterol levels significantly decreased with atorvastatin ( P = 0.03 ) . CONCLUSIONS High-dose atorvastatin did not reduce the recurrence of AF after CV . It reduced selective markers of inflammation without affecting systemic oxidative stress . Failure of atorvastatin to prevent AF recurrence may be due to its failure to affect oxidative stress Inflammation , oxidative stress , and high concentration of serum lipoprotein ( a ) [ Lp ( a ) ] are common complications in hemodialysis patients . The present study was design ed to investigate the effects of L-carnitine supplement on serum inflammatory cytokines , C-reactive protein ( CRP ) , Lp ( a ) , and oxidative stress in hemodialysis patients with Lp ( a ) hyperlipoproteinemia [ hyper Lp ( a ) ] . This was an unblinded , r and omized clinical trial . Thirty-six hyper Lp ( a ) hemodialysis patients ( 23 men and 13 women ) were r and omly assigned to either a carnitine or control group . Patients in the carnitine group received 1000 mg/d oral L-carnitine for 12 weeks , whereas patients in the control group did not receive any L-carnitine supplement . At baseline and the end of week 12 , 5 mL of blood were collected after a 12- to 14-hours fast and serum free carnitine , CRP , interleukin-1β , interleukin-6 ( IL-6 ) , tumor necrosis factor-α , Lp ( a ) , and oxidized low-density lipoprotein were measured . Serum free carnitine concentration increased significantly by 86 % in the carnitine group at the end of week 12 compared with baseline ( P<0.001 ) , while serum CRP and IL-6 showed a significant decrease of 29 % ( P<0.05 ) and 61 % ( P<0.001 ) , respectively . No significant changes were observed in serum free carnitine , CRP , and IL-6 in the control group . There were no significant differences between the two groups in mean changes of serum interleukin-1β , tumor necrosis factor-α , Lp ( a ) , and oxidized low-density lipoprotein concentrations . L-carnitine supplement  reduces inflammation in hemodialysis patients , but has no effect on hyper Lp ( a ) and oxidative stress
Bariatric surgery  significantly lowered inflammatory factors ; however , baseline BMI , follow-up duration and type of surgery could impact the extent of observed effects
Obesity is one of the main causes of inflammation .
Previous studies have reported inconclusive results regarding the effect of bariatric surgery on inflammatory markers .
This systematic review and meta- analysis is aim ed at describing the effect of bariatric surgery on C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) , tumor necrosis factor-α ( TNF-α ) .
