Aim: To evaluate the effects of orally administered gadolinium orthovanadate GdVO4:Eu3+ nanoparticles (VNPs) on the course of chronic carrageenan-induced intestinal inflammation. Methods: Samples of small intestinal tissue were collected from four groups of rats (intact, after administration of VNPs, with carrageenaninduced intestinal inflammation, with carrageenan-induced intestinal inflammation orally exposed to VNPs) to assess the intestinal morphology and HSP90α expression. Levels of seromucoid, C-reactive protein, TNF-α, IL-1β and IL-10 were determined in blood serum. Results: Oral exposure to VNPs was associated with neither elevation of inflammation markers in blood serum nor HSP90α overexpression in the small intestine, i.e. no toxic effects of VNPs were observed. Carrageenan-induced intestinal inflammation was accompanied by higher levels of TNF-α and IL-1β, as well as HSP90α upregulation in the intestinal mucosa, compared with controls. Administration of VNPs to rats with enteritis did not lead to statistically significant changes in concentrations of circulating pro-inflammatory cytokines with the trend towards their increase. Conclusion: No adverse effects were observed in rats orally exposed to VNPs at a dose of 20 μg/kg during two weeks. Using the experimental model of carrageenan-induced enteritis, it was demonstrated that VNPs at the dose used in our study did not affect the course of intestinal inflammation.

Patients with end-stage renal disease (ESRD) present alterations in mineral and bone metabolism. Hyperphosphatemia in ESRD is considered an independent risk factor for cardiovascular disease (CVD), increasing morbidity, and mortality. Sevelamer hydrochloride is a calcium-free, non-absorbable phosphate-chelating polymer. Calcium carbonate chelator is helpful in controlling serum phosphate levels. There is insufficient information on the influence of sevelamer hydrochloride and calcium carbonate on the behavior of oxidative stress (OS) markers and inflammation in patients on hemodialysis (HD). A randomized open clinical trial was carried out on patients to evaluate sevelamer hydrochloride and calcium carbonate influence at 6 months of study follow-up. Levels of oxidants (LPO, NO, and 8-isoprostanes), antioxidants (SOD and TAC), oxidative DNA damage (8-OHdG and hOGG1), pro-inflammatory cytokines (IL-6 and TNF-α), and inflammation markers (ferritin and C-reactive protein) were measured with colorimetric and ELISA methods. We found a significant increase in oxidants LPO and NO, and antioxidants SOD and TAC, and downregulation of IL-6 and TNF-α. Ferritin decrease at 6 months follow-up in the sevelamer hydrochloride group. Increase in C-reactive protein was found in the group of patients treated with calcium carbonate. In conclusion, we found an oxidative state imbalance with increase in LPO and NO oxidants. The activity of the antioxidant enzymes (SOD and TAC) was also found to increase, suggesting a compensatory effect in the face of increase in oxidants. The same phenomenon was observed with increase in the oxidative damage marker to DNA and the increase in the DNA repair enzyme, suggesting a compensatory effect. Pro-inflammatory cytokines were predominantly downregulated by TNF-α in the group that ingested sevelamer hydrochloride in the final determination at 6 months of follow-up. Serum ferritin levels decreased significantly at the end of follow-up in patients on HD in the sevelamer hydrochloride group. The management of hyperphosphatemia with sevelamer hydrochloride appears to have obvious anti-inflammatory and antioxidant benefits.

Objective: to evaluate the severity of immuno-inflammatory responses under stable stenocardia in patients with ischemic heart disease (IHD). Patients and intervention: the study included 83 patients suffering from IHD. Among them 30 cases were diagnosed as functional class (FC)-II stenocardia, 27 cases as FC-III stenocardia and 26 cases as FC-IV stenocardia. The control group included 25 healthy persons. For characterizing the immuno-inflammatory responses we examined the level of C-reactive protein (CRP), pro-inflammatory (IL-1b, IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines by the immunoenzymic procedure. Results: FC-II stenocardia showed normal levels of CRP and pro-inflammatory cytokines. FC-III stenocardia was associated with a moderate increase in markers of an inflammation. FC-IV stenocardia was characterized by maximum levels of CRP and pro-inflammatory cytokines. Conclusion. The intensity of immuno-inflammatory responses depends on more or less serious course of stenocardia in patients with IHD.

Background:: Ursolic Acid (UA) is a pentacyclic triterpenoid carboxylic acid which is extracted from plants. UA may enhance the effect of Resistance Training (RT) in human. Objective: Current research was designed to show the effect of High-Intensity Resistance Training (HIRT) in the presence or absence of UA on the serum levels of irisin, CRP, IL-6 and TNF-α in the low activity men. Method:: The study included twenty-two healthy male HIRT with placebo, supplementation, and HIRT in the presence of UA supplementation. The two groups received eight-week intervention including 2 sets of 8 exercises, with 8~10 repetitions at 70~75% of 1 repetition maximum and a 2 min rest interval between sets, performed 3 times/week. Placebo or UA orally was evaluated as 1 capsule 3 times/day during 8 weeks. The subsequent factors were measured post- and preintervention: C-Reactive Protein (CRP), Irisin, Tumor Necrotic Factor (TNF-α) and Interleukin-6 (IL-6). Results:: UA supplementation significantly increased the plasma levels of irisin in the HIRT+UA group versus the HIRT+P group (p<0.05). UA treatment also dramatically decreased the plasma levels of CRP, IL-6, and TNF-α in the HIRT+UA group versus the HIRT+P group (p<0.05). Conclusion:: The current data showed that UA-induced an increase in serum irisin and reduction of CRP, IL-6, and TNF-α may have beneficial effects as a chemical for increasing of the effects of HIRT in low activity men.

Background:Spondyloarthritis is a group of chronic inflammatory diseases involving axial and peripheral joints. It mainly affects young patients typically of working age. Therefore, its impact on work outcomes may be considerable particularly in military patients.Objectives:The aim of this study was to evaluate the impact of spondyloarthritis on work ability and productivity in military patients, and to assess relationship between work productivity loss and disease activity.Methods:Thirty Three patients diagnosed with spondyloarthritis in the militay hospital of Tunis were included in the study. Age, gender and C-reactive protein were recorded. Data related to duration of the disease, Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were also recorded. Employed patients completed Work Productivity and Activity Impairment (WPAI) questionnaire witch assesses four subscales: presenteism, absenteism, overall work impairemend and daily activity impairement in the 7 past days.Results:Among the thirty three patients, 63 % were men and 37% were women. The average age was 43,7 ± 13,5. The average duration of disease was 8,5 ± 7,75 years. Mean C-Reactive protein was 27,5 ± 39,3. Mean ASDAS and BASDAI were 3,12 ± 1,39 and 4,26 ± 1,78 respectively. 22 patients (66%) had an active disease and 11 (33%)were in remission. 48,4% of patients were using NSAIDs, 48,4% were under DMARDs and 42% were under biologics (12 patients using TNF-alpha blockers and 2 patients were given IL-17 inhibitors). Among this patients, 27 were employed. Three patients (11%) had a total work disability and were retired from work and two have been outplaced.Employed patients worked an average of 35,6 ± 10,3 hours per week and missed an average of 3,48 ± 6,49 hours per week. The mean rates of absenteeism, presenteeism and work productivity loss were 8,8 ± 16,9 %, 48,4 ± 19,9 % and 48,6 ± 19,7 %.There was a statistically significant correlation between BASDAI and work missed hours (p<0,05, r=0,48), absenteeism (p<0,05, r=0,48), presenteeism (p<0,01, r=0,669), work impairement (p<0,01, r=0,669), activity impairement (p<0,05, r=0,475) and work productivity loss (p<0,05, r=0,475), as well as between ASDAS CRP and presenteeism (p<0,05, r= 0,593), work impairement (p<0,05, r=0,593), activity impairement(p<0,05, r=0,460) and work productivity loss (p<0,05, r=0,460). No relation was found between WPAI indexes and C-reactive protein.Conclusion:This study demonstrates that spondyloarthritis has a major impact on military patients’ work productivity with a significant correlation between WAPI indexes and disease activity scores (ASDAS CRP and BASDAI). No relation was found with C-reactive protein.Disclosure of Interests:None declared.

The impact of diet and fibre fractions on adipocytokines in obese subjects with a risk of diabetes has not been investigated in detail yet. The purpose of the study is to evaluate the effects of a 12-month lifestyle intervention with different fibre profiles (resistant starch (RS)—rich fibre, or ordinary food fibre profiles) on adipocytokine levels. Fifty participants are divided into two groups (RS group and Fibre group). The groups differ only in the percentage of the recommended level of the RS consumed as a fraction of the same total fibre amount. The applied dietary intervention includes intake of 7531 KJ/daywith a total fibre portion of 25–35 g/dayfor both groups that includes 15 g/day of RS for the RS group only. The levels of leptin, adiponectin, apelin, resistin, tumor necrosis factor (TNF)-alpha and C-reactive protein (CRP) are measured, and their relationship to anthropometric and biochemical parameters is estimated. Along with significant body weight loss, only leptin is significantly reduced by 13% in the RS group while in the Fibre group, apelin levels are significant (−21%). Polynomial regression shows a negative correlation between RS intake and adiponectin (R2 = 0.145) and resistin level (R2 = 0.461) in the RS group. This study indicates the possibility that fibre fractions differently influence the outcome of lifestyle interventions, as well as their adipocytokine levels, in obese prediabetic adults.

Metalloproteinase 9

Matrix metalloproteinase-9 (MMP-9) has been shown to play a key role in endothelial function and perhaps pivotal in the correlation between periodontal disease and cardiovascular disease (CVD). For the study, the impact of MMP-9 of periodontitis and CVD on serum and saliva concentrations was analyzed. For the study patients with periodontitis (n = 31), CVD (n = 31), periodontitis + CVD (n = 31), and healthy patients (n = 31) were enrolled. Clinical and demographic characteristics as well as serum and salivary MMP-9 were evaluated. MMP-9 concentrations in serum and saliva were statistically elevated in patients with CVD (p < 0.01) and in patients with periodontitis plus CVD (p < 0.001) compared to patients with periodontitis and healthy subjects. Multivariate regression analysis showed that c-reactive protein (hs-CRP) was the only significant predictor for MMP-9 serum (p < 0.001), whereas hs-CRP (p < 0.001) and total cholesterol (p = 0.029) were the statistically significant salivary MMP-9 predictors. This study evidenced that patients with CVD and periodontitis + CVD presented elevated MMP-9 concentrations in serum and saliva compared to patients with periodontitis and healthy subjects. Furthermore, hs-CRP was a negative predictor of serum and salivary MMP-9.

The Impact

Introduction: In the US, blacks are at higher risk of hypertension than whites. The single largest contributor to this disparity is the Southern Diet pattern. Inflammation biomarkers are associated with risk of hypertension, and C-reactive protein (CRP) is higher in blacks than whites. We studied whether elevated CRP in blacks relative to whites contributes to the racial disparity in hypertension in blacks. Methods: We included 6,548 black and white men and women age ≥45 years from the REGARDS cohort without hypertension at baseline ('03-'07) and who completed visit 2 in '13-'16. Incident hypertension was defined as BP ≥140/90 mm Hg or hypertension medication use at visit 2. Using logistic regression, the black:white odds ratio (OR) for incident hypertension was calculated adjusting for age, sex, race, and baseline SBP. We assessed the percent change in the black:white OR for incident hypertension after adding CRP. The 95% CI was calculated using 1,000 bootstrapped samples. We determined the impact of known hypertension risk factors and anti-inflammatory medications on the percent mediation by CRP. Results: Hypertension developed in 46% of blacks and 33% of whites. Adjusting for demographics, the black:white OR (95% CI) was 1.51, which was reduced to 1.46, a 9.3% reduction (95% CI 5.4%, 13.2%) by CRP (Table). In models including exercise, waist circumference, BMI, and depressive symptoms, the percent mediation by CRP was 3.7% (1.0%, 6.4%). Similar patterns were seen for models incorporating socioeconomic factors and medication use. After adding Southern diet pattern and dietary Na/K ratio, CRP no longer attenuated the association (1.3% mediation; -1.5, 4.1). Conclusions: CRP significantly attenuated the black-white difference in incident hypertension; however, once dietary factors were accounted for, CRP had no impact on the black:white difference in incident hypertension. Thus, inflammation as measured by CRP, may be part of the reason that dietary factors influence the black:white disparity in incident hypertension.
