ObjectiveIt was aimed to evaluate the relationship between proinflammatory cytokine levels and conversion disorder both commonly known as stress regulated.MethodBaseline proinflammatory cytokine levels–[Tumour necrosis factor alpha (TNF‐α), Interleukin‐1 beta (IL‐1β), Interleukin‐6 (IL‐6)]–were evaluated with enzyme‐linked immunosorbent assay in 35 conversion disorder patients and 30 healthy controls. Possible changes in proinflammatory cytokine levels were evaluated again, after their acute phase in conversion disorder patients.ResultsStatistically significant decreased serum TNF‐α levels were obtained in acute phase of conversion disorder. Those levels increased after acute conversion phase. There were no statistically significant difference observed between groups in serum IL‐1β and (IL‐6) levels.ConclusionsStress associated with conversion disorder may suppress immune function in acute conversion phase and may have diagnostic and therapeutic value.

Experimental Pneumococcal Meningitis

ABSTRACT The polysaccharide fucoidin is a selectin blocker that inhibits leukocyte recruitment into the cerebrospinal fluid (CSF) during experimental pneumococcal meningitis. In the present study, the effect of fucoidin treatment on the release of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and IL-8 into the CSF was investigated. Rabbits (n = 7) were treated intravenously with 10 mg of fucoidin/kg of body weight every second hour starting 4 h after intracisternal inoculation of ∼106 CFU of Streptococcus pneumoniae type 3 (untreated control group, n = 7). CSF samples were obtained every second hour during a 16-h study period. Treatment with fucoidin caused a consistent and significant decrease in CSF IL-1 levels (in picograms per milliliter) between 12 and 16 h (0 versus 170, 0 versus 526, and 60 versus 1,467, respectively;P < 0.02). A less consistent decrease in CSF TNF-α levels was observed in the fucoidin-treated group, but with no significant difference between the two groups (P > 0.05). In contrast, there was no attenuation in CSF IL-8 levels. Indeed, there was a significant increase in CSF IL-8 levels (in picograms per milliliter) in the fucoidin-treated group at 10 and 12 h (921 versus 574 and 1,397 versus 569, respectively;P < 0.09). In conclusion, our results suggest that blood-derived leukocytes mainly are responsible for the release of IL-1 and to some degree TNF-α into the CSF during pneumococcal meningitis, whereas IL-8 may be produced by local cells within the brain.

Abstract Background Limited research is available concerning the relationship between oxidative stress and inflammation parameters, and simultaneously the effects of rosuvastatin on these markers in patients with hypercholesterolemia. We aimed to investigate the connection between cytokines and oxidative stress markers in patients with hypercholesterolemia before and after rosuvastatin treatment. Methods The study consisted of 30 hypercholesterolemic patients diagnosed with routine laboratory tests and 30 healthy participants. The lipid parameters, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), paraoxonase-1 (PON1) and malondialdehyde (MDA) levels in controls and patients with hypercholesterolemia before and after 12-week treatment with rosuvastatin (10 mg/kg/day), were analyzed by means of enzyme-linked immunosorbent assay. Results It was found that a 12-week cure with rosuvastatin resulted in substantial reductions in IL-1β, IL-6 and TNF-α and MDA levels as in rising activities of PON1 in patients with hypercholesterolemia. Before treatment, the PON1 levels were significantly negatively correlated with TNF-α and IL-6 in control group, while it was positively correlated with TNF-α in patients. Conclusion Our outcomes provide evidence of protected effect of rosuvastatin for inflammation and oxidative damage. It will be of great interest to determine whether the correlation between PON1 and cytokines has any phenotypic effect on PON1.

Heart failure (HF) is a syndrome with multiple clinical phenotypes affecting around 1%–2% of adult population worldwide, and about 230 million Chinese are affected by cardiovascular diseases. The important role of pro-inflammatory plasma cytokines with HF has been demonstrated in different populations. The aim of this study was to investigate importance of pro-inflammatory cytokines in Chinese HF patients. In all, 134 HF patients were enrolled in this study and further classified in to four clinical distinct groups according to New York Heart Association classification criteria (NYHA-I: n = 34, NYHA-II: n = 35, NYHA-III: n = 22 and NYHA-IV: n = 43). Sixty-eight healthy Chinese were enrolled as controls. Plasma levels of tumour necrosis factor-α (TNF-α), TNF-receptor 1 (TNFRI), TNF-receptor 2 (TNFRII), interleukin 6 (IL-6), soluble IL-6 receptor (sIL-6R), C-reactive protein (CRP), soluble cluster of differentiation 14 (sCD14) and interleukin 1 beta (IL-1β) were quantified by enzyme-linked immunosorbent assay (ELISA). Plasma levels of all parameters investigated in this study remained comparable among healthy controls and NYHA-I group. Plasma levels of TNF-α, TNFRI, TNFRII, IL-6, sIL-6R, CRP, sCD14 and IL-1β were significantly higher in NYHA-III and NYHA-IV clinical categories compared to other HF phenotype (NYHA-I and NYHA-II). Interestingly, TNFR-II levels were significantly higher in NYHA-II compared to NYHA-I. No significant difference of plasma sIL-6R was observed among various clinical categories. In conclusion, plasma levels of pro-inflammatory molecules are elevated in severe HF patients and may be used as possible biomarkers for accessing severity of HF.

ABSTRACT Infection with Neisseria meningitidis serogroup B is responsible for fatal septicemia and meningococcal meningitis. The severity of disease directly correlates with the production of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), IL-6, and IL-8. However, the source of these cytokines has not been clearly defined yet. Since bacterial infection involves the activation of dendritic cells (DCs), we analyzed the interaction of N. meningitidis with monocyte-derived DCs. Using N. meningitidis serogroup B wild-type and unencapsulated bacteria, we found that capsule expression significantly impaired neisserial adherence to DCs. In addition, phagocytic killing of the bacteria in the phagosome is reduced by at least 10- to 100-fold. However, all strains induced strong secretion of proinflammatory cytokines TNF-α, IL-6, and IL-8 by DCs (at least 1,000-fold at 20 h postinfection [p.i.]), with significantly increased cytokine levels being measurable by as early as 6 h p.i. Levels of IL-1β, in contrast, were increased only 200- to 400-fold at 20 h p.i. with barely measurable induction at 6 h p.i. Moreover, comparable amounts of cytokines were induced by bacterium-free supernatants of Neisseria cultures containing neisserial lipooligosaccharide as the main factor. Our data suggest that activated DCs may be a significant source of high levels of proinflammatory cytokines in neisserial infection and thereby may contribute to the pathology of meningococcal disease.

The Central Nervous System

Multiple sclerosis (MS) is the most common neurological disease that happens at a young age. MS is an inflammatory disease; associated with the demyelination of the central nervous system. Therefore, some inflammatory factors are effective in the mechanism and progression of the disease. Melatonin, as a multi-effect substance including anti-inflammatory effects, can reduce symptoms of MS in patients with a change in their inflammatory factors level. In this study, 50 MS patients who were referred to the MS Society of Markazi Province were randomly selected. All patients were treated with routine MS treatment (interferon) and were divided into control (25 placebo recipients) and treatment (25 recipients of 3 mg melatonin per day for 24 weeks) groups. Anthropometric data of patients including height, weight, and age were determined. Blood samples were collected after fasting in order to determine serum levels of interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α). Then, samples were immediately centrifuged for serum separation and sera were transferred to a freezer at -80°C and serum levels of these factors were determined; using ELISA kit. The results of this study showed that there was no significant difference between the control and treatment groups in terms of serum levels of TNF-α. However, the level of IL-1β was significantly reduced in the treatment group compared to the control group, indicating that melatonin decreases this inflammatory substance. Our findings suggest a valuable strategy in the treatment of patients who suffer from MS

Lipopolysaccharide (LPS), also known as endotoxin, can trigger septic shock, a severe form of inflammation-mediated sepsis with a very high mortality rate. However, the precise mechanisms underlying this endotoxin remain to be defined and detoxification of LPS is yet to be established. Macrophages, a type of immune cells, initiate a key response responsible for the cascade of events leading to the surge in inflammatory cytokines and immunopathology of septic shock. This study was undertaken to determine whether the LPS-induced inflammation in macrophage cells could be ameliorated via CDDO-IM (2-cyano-3,12 dioxooleana-1,9 dien-28-oyl imidazoline), a novel triterpenoid compound. Data from this study show that gene expression levels of inflammatory cytokine genes such as interleukin-1 beta (IL-1β), interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) were considerably increased by treatment with LPS in macrophages differentiated from ML-1 monocytes. Interestingly, LPS-induced increase in expression of pro-inflammatory cytokine levels is reduced by CDDO-IM. In addition, endogenous upregulation of a series of antioxidant molecules by CDDO-IM provided protection against LPS-induced cytotoxicity in macrophages. LPS-mediated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) transcriptional activity was also noted to decrease upon treatment with CDDO-IM in macrophages suggesting the involvement of the NF-κB signaling. This study would contribute to improve our understanding of the detoxification of endotoxin LPS by the triterpenoid CDDO-IM.

Objective. The present study was planned to examine the relationships between obstructive sleep apnea syndrome (OSAS) and the newly revealed adipokines adropin and adiponectin concentrations that display significant metabolic and cardiovascular functions and the levels of proinflammatory cytokine levels. Method. A total of 166 overweight and obese male patients with a body mass index (BMI) >27 kg/m2 were included in the study. Among study participants, 84 were recently diagnosed with OSAS by polysomnography with an apnea-hypopnea index (AHI) ≥5, and 82 were nonapneic with normal polysomnography (AHI<5) findings. The serum adropin and adiponectin levels of all cases were analyzed via the enzyme-linked immunosorbent assay method. Serum interleukin-1 (IL-1) beta and tumor necrotizing factor-alpha (TNF-alpha) levels were determined using Luminex cytokine multiplex analyses. Results. The mean age of the OSAS patients was 50.9 ± 5.7 years and BMI was 32.4 ± 6.0 kg/m2, and there was no statistically significant difference determined with the control group (49.3 ± 5.8 years and 30.6 ± 5, 6 kg/m2) (p>0.05). There were no statistically significant differences between the OSAS and control groups concerning total cholesterol, triglyceride, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and glucose levels. Adiponectin was lower in the OSAS group at a statistically significant level in comparison with the control group and was related at a statistically significant level to OSAS intensity. Adropin concentration was determined to be higher in the OSAS group at a statistically significant level in comparison with the control group. Conclusion. The results of our study suggest that increased adropin concentration may be an indicator of endothelium dysfunction in OSAS patients. Serum adropin and adiponectin levels may be new bioindicators used for diagnosis and risk assessment in OSAS patients.

ABSTRACT Cytokine levels were compared between schistosomiasis patients affected by intense fibrosis defined by ultrasound examination and graded from F-0 to F-3. The concentrations of interleukin-1β (IL-1β), IL-4, IL-5, IL-10, IL-13, gamma interferon, and tumor necrosis factor alpha (TNF-α) were determined by enzyme-linked immunosorbent assay of serum samples. Levels of IL-4, IL-5, and TNF-α in the sera of F-3 patients were significantly higher than those found in F-0 individuals, while levels of IL-13 were lower. Levels of IL-4, IL-5, and TNF-α in serum were significantly higher in F-3 males than in F-0 males or F-3 females. Conversely, levels of IL-13 were significantly lower in F-3 females than in F-0 females and males.

This study was to investigate the inhibitive effect of resveratrol (RESV) on nuclear factor kappa B (NF-κB) expression and activity induced by lipopolysaccharide (LPS) in rat peritoneal macrophages (PMA). Male Sprague-Dawley (SD) rats were randomly divided into 7 groups, including control group, LPS group and RESV I-V group. In the LPS group, PMA were incubated in DMEM containing LPS (10 μg/ml), whereas in control group, PMA were incubated in DMEM only. In the RESV I-V groups, PMA were incubated in DMEM containing LPS (10 μg/ml) and different concentrations of RESV. After 24 hours of incubation, NF-κB activity in PMA, and the levels of tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1) and nitric oxide (NO) in the culture medium were measured. In the concentrations of 1.25-5 μg/ml, RESV had a dose- dependent inhibitive effect on NF-κB activity in PMA as well as the expressions of TNF-α, IL-1 and NO in the culture medium contrasted with the LPS group. There was no significant difference in the levels of these pro-inflammatory factors between the groups of 5 μg/ml and 10 μg/ml RESV. In conclusion, RESV has the potential for the future application of preventing inflammatory diseases involving PMA.
