Abstract
BACKGROUND Trauma is associated with a profound immunological dysfunction. This predisposes patients to infections and adverse outcomes. ß-glucan has been implicated in the initiation of anti-microbial immune response. The present study aimed to evaluate the effects of an enteral diet containing ß-glucan on serum levels of IL-12 and highly-sensitive C-reactive protein (hs-CRP), occurrence of infection, and clinical outcomes in critically ill multiple-trauma patients. METHODS Forty multiple trauma patients requiring enteral nutrition for at least 10 days were randomly assigned to the intervention group (n=20) or the placebo group (n=20). The intervention group received a high-protein enteral diet providing 3 g ß-glucan, and the control group received a similar diet, except for 3 g of maltodextrin as a placebo. Serum levels of IL-12 and hs-CRP were measured on days 0, 10, and 21. RESULTS The ß-glucan group showed significantly higher serum levels of IL-12 on day 21 compared to the control group. Infection frequency and duration of mechanical ventilation were significantly lower in the ß-glucan group. A significant difference was found in the Sequential Organ Failure Assessment (SOFA) score in favor of the ß-glucan group. No difference was found in the serum levels of hs-CRP, length of ICU stay, occurrence of infection, and mortality rates between the two groups. CONCLUSION ß-glucan may increase serum levels of IL-12, shorten the duration of mechanical ventilation, and reduce organ failure in critically ill multiple-trauma patients.

Abstract
PURPOSE In regard with the effect of immune-stimulants in the treatment of infectious diseases, the effect of vitamin D administration on the outcome of patients with Ventilator-Associated Pneumonia (VAP) with a high rate of mortality, was studied. MATERIAL AND METHOD In this trial, 46 adult patients suffering from VAP and vitamin D deficiency were enrolled. The first group of patients received single intramuscular injection of vitamin D (300000Unit), while the other group were given the placebo. RESULTS Administration of vitamin D significantly enhanced its levels (P<0.0001) in the treated patients (12.28±8.26) in comparison with placebo group (1.15±1.50). Serum Interleukin-6 levels were significantly reduced in the treated group compared to placebo (P=0.01). Although C-Reactive protein (CRP) levels showed an improving trend in the vitamin D group, no significant difference between groups (P=0.12) was found. Interestingly, the mortality rate of patients that treated with vitamin D (5/24) was significantly lower (p=0.04) than that of the placebo group (11/22). CONCLUSION Our results indicate that vitamin D administration can significantly reduce the IL-6 as prognostic marker in VAP patients, and must be considered as adjunct option in the treatment of VAP patients.

Abstract
BACKGROUND Balance in the immune system plays roles in bipolar disorder (BD) and its metabolic co-morbidities. Memantine is an NMDA receptor antagonist with anti-inflammatory effects. However, the effects of memantine adjunct treatment on metabolic status of BD are unclear. METHODS During the 12 weeks period, a total of 191 BD patients were enrolled and split into valproate (VPA) + placebo and VPA + memantine (5mg/day) arms. The fasting plasma levels of high-sensitivity C-reactive protein (CRP) and metabolic indices were assessed. BD patients were stratified according to their initial CRP level. RESULTS A cut-off value of initial CRP level of 2322ng/mL discriminated the waist circumference in these BD patients after 12-week VPA treatment. In the high CRP (> 2322ng/mL) group, patients in the VPA + memantine arm had a significantly decreased in their CRP (p= 0.009), total cholesterol (p= 0.002), LDL (p= 0.002) levels, BMI (p= 0.001), and waist circumference (p< 0.001), compared to those in the VPA + placebo arm. However, analysis of the low CRP group did not showed the effect. LIMITATIONS We recruited BD patients in depressed states and the sample size was relative small. The effects of the fixed dose of memantine on metabolic indices were 12-week follow up in BD patients treated with VPA. CONCLUSIONS BD patients with high initial CRP levels receiving memantine adjunct treatment have a reduced risk of inflammation and metabolic imbalance. Prospective studies are needed to confirm the long-term outcome for memantine adjunct therapy in BD patients.

Abstract
Background: Ferritin and hepcidin are markers of iron status that typically increase during inflammation or infection. The postpartum period is a physiologically unique life stage in which the relations between these proteins and other markers of inflammation have not been extensively studied.Objective: We aimed to determine whether 2 markers of inflammation [high-sensitivity C-reactive protein (CRP) and α1-acid glycoprotein (AGP)] were associated with ferritin or hepcidin in postpartum women in California.Methods: This is a secondary analysis of a randomized controlled iron-intervention trial. Plasma CRP, AGP, ferritin, and hepcidin were analyzed at 2 and 17 wk postpartum in 114 lactating women. We examined Pearson correlation coefficients between all biomarkers at both time points and differences in mean values of ferritin and hepcidin between those with and without elevated CRP and/or AGP.Results: At 2 and 17 wk postpartum, 58% and 26% of women had CRP >5 mg/L and 78% and 29% had AGP >1 g/L, respectively. Neither CRP nor AGP was significantly correlated with ferritin (r = 0.07 and -0.06; n = 114 at 2 wk; -0.14 and -0.14; n = 95 at 17 wk) or hepcidin (r = 0.18 and -0.03 at 2 wk; -0.05 and -0.14 at 17 wk; P > 0.05 for all). At 2 wk, geometric mean plasma ferritin and hepcidin concentrations did not differ between women with and without elevated CRP or AGP (P > 0.5), but at 17 wk women with elevated CRP or AGP had lower mean (95% CI) ferritin and hepcidin than did women without either elevated CRP or AGP [ferritin: 30.3 ng/mL (23.4, 39.1 ng/mL) compared with 40.2 ng/mL (32.9, 49.2 ng/mL); P < 0.01; hepcidin: 44.3 ng/mL (32.3, 60.9 ng/mL) compared with 67.6 ng/mL (56.1, 81.5 ng/mL); P = 0.02].Conclusion: Lower ferritin and hepcidin among women with elevated CRP or AGP at 17 wk postpartum suggests that these markers of iron status react differently to physiologic immune activation than to pathologic inflammatory states.

Abstract
BACKGROUND Vitamin D is a potent immunomodulator and may play a role in the development of the fetal innate immune functions. The aim of our study was to evaluate inflammatory markers in cord blood of healthy newborns in relation to vitamin D status at birth. METHODS We studied the concentrations of inflammatory markers, matrix metalloproteinase 8 (MMP-8) and high sensitivity CRP (hs-CRP), and 25-hydroxyvitamin D (25(OH)D) in cord blood of 939 healthy term infants born to mothers of Caucasian origin. We evaluated perinatal factors that affect the concentrations of MMP-8 and hs-CRP, and further explored associations between cord blood 25(OH)D and these inflammatory biomarkers. RESULTS Majority (99%) of the cohort was vitamin D sufficient (>50 nmol/l or 20 ng/ml). We observed a positive correlation between cord blood 25(OH)D and MMP-8 concentrations, and between 25(OH)D and hs-CRP concentrations. After adjustment for potential confounders (parity, antenatal antibiotic treatment, gestational age, mode of delivery, and maternal prepregnancy BMI), the association of 25(OH)D with MMP-8 and hs-CRP remained significant. CONCLUSION Cord blood 25(OH)D correlates with inflammatory markers MMP-8 and hs-CRP. The findings may reflect the diverse immunomodulatory functions of vitamin D in the innate immune response of the newborn.

Abstract
ERAS program applied to colorectal laparoscopic surgery is well known to reduce hospitalization improving short terms outcomes and minimizing the Surgical Stress Response. However its effectiveness in elderly population is yet to be demonstrated. The primary aim of this study is to compare the level of immune and nutritional serum indexes across surgery in patients aged over 70 years old undergoing elective colorectal laparoscopic surgery within an ERAS protocol or according to a Standard program. 83 patients undergoing colorectal laparoscopic surgery were enrolled and randomized in two groups (ERAS Group 40, Standard Group 43) within a larger randomized trial on a general population. Surgical stress parameters were collected preoperatively, 1, 3 and 5 days after surgery. Nutritional parameters were collected preoperatively, 1 and 5 days after surgery. Short Term Outcomes were also prospectively assessed. IL-6 levels were lower in the EG on 1, 3, and 5 days post-operatively (p 0.05). IL-6 levels in the Enhanced group returned to pre operative level 3 days after surgery. C-reactive protein level was lower in the Enhanced group on day 1, 3, and 5 (p 0.05). There was no difference in Cortisol and Prolactin levels between groups. Prealbumin serum level was higher on day 5 (p 0.05) compared to standard group. Postoperative outcomes in terms of normal bowel function and length of hospital stay were significantly improved in the ERAS group. Colorectal laparoscopic surgery within an ERAS prototcol in elderly patients affects Surgical Stress Response, decreasing IL-6 and CRP levels postoperatively and improving Prealbumin post operative synthesis.

PloS one. 2012;(3):e33108
Abstract
BACKGROUND A recent randomized placebo-controlled trial of the effect of atorvastatin treatment on the progression of newly diagnosed type 1 diabetes suggested a slower decline of residual beta cell function with statin treatment. Aim of this secondary analysis was to identify patient subgroups which differ in the decline of beta cell function during treatment with atorvastatin. METHODOLOGY/PRINCIPAL FINDINGS The randomized placebo-controlled Diabetes and Atorvastatin (DIATOR) Trial included 89 patients with newly diagnosed type 1 diabetes and detectable islet autoantibodies (mean age 30 years, 40% females), in 12 centers in Germany. Patients received placebo or 80 mg/d atorvastatin for 18 months. As primary outcome stimulated serum C-peptide levels were determined 90 min after a standardized liquid mixed meal. For this secondary analysis patients were stratified by single baseline characteristics which were considered to possibly be modified by atorvastatin treatment. Subgroups defined by age, sex or by baseline metabolic parameters like body mass index (BMI), total serum cholesterol or fasting C-peptide did not differ in C-peptide outcome after atorvastatin treatment. However, the subgroup defined by high (above median) baseline C-reactive protein (CRP) concentrations exhibited higher stimulated C-peptide secretion after statin treatment (p = 0.044). Individual baseline CRP levels correlated with C-peptide outcome in the statin group (r(2) = 0.3079, p<0.004). The subgroup with baseline CRP concentrations above median differed from the corresponding subgroup with lower CRP levels by higher median values of BMI, IL-6, IL-1RA, sICAM-1 and E-selectin. CONCLUSIONS/SIGNIFICANCE Atorvastatin treatment may be effective in slowing the decline of beta cell function in a patient subgroup defined by above median levels of CRP and other inflammation associated immune mediators.

Abstract
OBJECTIVES A randomized controlled clinical trial was performed to examine the effectiveness of auricular acupuncture on body weight loss and its impact on lipid profile, and immunologic and inflammatory markers in obese subjects. METHODS Participants (n=204) were randomized to therapeutic acupuncture and control groups. Subjects received authentic (cases) or sham (controls) acupuncture for 6 weeks (first period) in combination with a low-calorie diet. In the next 6 weeks (second period), the low-calorie diet was used on its own. Subjects were assessed at the beginning and 6 and 12 weeks later. In addition to anthropometric and lipid parameters, serum anti-heat shock protein (Hsp)-27, 60, 65, 70 and high sensitive C-reactive protein (hs-CRP) levels were assessed. RESULTS In the first period, anthropometric parameters and hs-CRP changed significantly in both groups, while significant changes in anti-Hsp antibodies were only observed in case subjects. In the second period, which shows the sustainable effects of acupuncture, changes in anthropometric parameters were more prominent in controls, while significant reductions in the group receiving authentic acupuncture were maintained for anti-Hsp antibodies. A comparison between the first and second period in both groups showed that the changes for most of the parameters were more significant in the first period. Comparison between cases and controls showed that authentic acupuncture was more effective in reducing the levels of anthropometric factors and anti-Hsp antibodies but not hs-CRP. CONCLUSIONS Auricular acupuncture in combination with diet restriction was effective for weight loss and dyslipidemia. Moreover, it was found that it has immunomodulatory but not anti-inflammatory effects on the immune system by regulation of the levels of anti-Hsp antibodies.

Abstract
OBJECTIVES A central hypothesis of the cholinergic anti-inflammatory reflex model is that innate immune activity is inhibited by the efferent vagus. We evaluated whether changes in markers of tonic or reflex vagal heart rate modulation following behavioural intervention were associated inversely with changes in high-sensitivity C-reactive protein (hsCRP) or interleukin-6 (IL-6). DESIGN Subjects diagnosed with hypertension (n = 45, age 35-64 years, 53% women) were randomized to an 8-week protocol of behavioural neurocardiac training (with heart rate variability biofeedback) or autogenic relaxation. Assessments before and after intervention included pro-inflammatory factors (hsCRP, IL-6), markers of vagal heart rate modulation [RR high-frequency (HF) power within 0.15-0.40 Hz, baroreflex sensitivity and RR interval], conventional measures of lipoprotein cholesterol and 24-h ambulatory systolic and diastolic blood pressure. RESULTS Changes in hsCRP and IL-6 were not associated with changes in lipoprotein cholesterol or blood pressure. After adjusting for anti-inflammatory drugs and confounding factors, changes in hsCRP related inversely to changes in HF power (β = -0.25±0.1, P = 0.02), baroreflex sensitivity (β = -0.33±0.7, P = 0.04) and RR interval (β = -0.001 ± 0.0004, P = 0.02). Statistically significant relationships were not observed for IL-6. CONCLUSIONS Changes in hsCRP were consistent with the inhibitory effect of increased vagal efferent activity on pro-inflammatory factors predicted by the cholinergic anti-inflammatory reflex model. Clinical trials for patients with cardiovascular dysfunction are warranted to assess whether behavioural interventions can contribute independently to the chronic regulation of inflammatory activity and to improved clinical outcomes.

Brain, behavior, and immunity. 2009;(4):485-91
Abstract
C-reactive protein (CRP) is an independent risk factor for cardiovascular disease. We sought to determine (1) if 10 months of cardiovascular exercise training (Cardio) reduces CRP in a group of older adults, (2) if such a reduction is related to improvements in trunk fat, fitness, and/or psychosocial variables, and (3) if the effect of Cardio on CRP differs between men and women. Community-dwelling residents (n=127; 60-83 yrs) were randomized to a Flex group (n=61) where they participated in 2-75 min supervised sessions per wk during which they performed non-cardiovascular flexibility and balance exercises or a Cardio group (n=66) where they participated in three supervised sessions per wk during which they performed cardiovascular exercises for approximately 45-60 min at 60-70% maximal oxygen uptake. The main outcome measures were serum CRP, cardiovascular fitness, total and central adiposity, and self-reported psychosocial function. Cardio experienced a reduction in CRP (-0.5mg/L), as well as improvements in fitness (+7%) and total (-1.5%) and central (i.e., trunk) (-2.5%) adiposity. These relationships were not modified by sex. Regression analyses indicated that only the reduction in trunk fat was significantly related to the reduction in CRP. Ten months of cardiovascular exercise training reduced CRP in previously sedentary older adults and this effect was partially mediated by a reduction in trunk fat.
