Irritable bowel syndrome in celiac disease - relationships to celiac disease antibodies and levels of pro-inflammatory cytokines / Síndrome del intestino irritable en la enfermedad celíaca: relaciones con los anticuerpos contra la enfermedad celíaca y los niveles de citocinas proinflamatorias

ABSTRACT Background: Evidence indicates that low-grade inflammation can alter gastrointestinal motor and sensory function and might contribute to the genesis of symptoms in IBS. Objective: To examine relationships between IBS, disease antibodies and cytokine titers in celiac patients and a control group. Materials and methods: IBS, CD activity and serum levels of IL-6, IL-8 and IL12/23p40 were determined in celiac patients and controls. Results: 123 celiac patients were included, 89% were female. 59% demonstrated disease activity and 32% met IBS criteria. Prevalence of IBS was not different between patients who adhered or did not adhere to GFD as well as between patients with or without positive antibodies. Celiac patients had increased levels of IL-6, IL-8 and IL12/23p40 as compared to controls. Higher levels of cytokines were found in celiac patients with IBS than in those without IBS. No difference in levels of cytokines was found between patients with and without CD positive antibodies. A significant negative correlation between the mental component of QoL and IL-6 and IL12/23p40 levels was found, but not with IL-8. Conclusion: Higher levels of inflammatory cytokines were found in CD patients with IBS than in either those without IBS or controls, indicating that IBS symptoms are associated with an increase in the inflammatory response and a decrease in quality of life of CD patients. These differences in cytokine levels were not related to CD antibodies status suggesting that IBS, in CD, is related to a different inflammatory process than that which is relevant to CD.

RESUMEN Antecedentes: la evidencia indica que la inflamación de bajo grado puede alterar la función motora y sensorial gastrointestinal y puede contribuir a la aparición de síntomas en el SII. Objetivo: Examinar la relación entre SII, anticuerpos contra enfermedades y títulos de citocinas en pacientes celíacos y un grupo de control. Materiales y métodos: se determinaron los síntomas de SII, actividad de CD y niveles séricos de IL-6, IL-8 e IL12 / 23p40 en pacientes celíacos y controles. Resultados: se incluyeron 123 pacientes celíacos, el 89% eran mujeres. El 59% demostró actividad de la enfermedad y el 32% cumplió con los criterios del SII. La prevalencia del SII no fue diferente entre los pacientes que se adhirieron o no se adhirieron a GFD, así como entre los pacientes con o sin anticuerpos positivos. Los pacientes celíacos tenían niveles aumentados de IL-6, IL-8 e IL12 / 23p40 en comparación con los controles. Se encontraron niveles más altos de citocinas en pacientes celíacos con SII que en aquellos sin SII. No se encontraron diferencias en los niveles de citocinas entre pacientes con y sin anticuerpos CD positivos. Se encontró una correlación negativa significativa entre el componente mental de la calidad de vida y los niveles de IL-6 e IL12 / 23p40, pero no con IL-8. Conclusión: Se encontraron niveles más altos de citocinas inflamatorias en pacientes con EC con SII que en aquellos sin SII o controles, lo que indica que los síntomas del SII están asociados con un aumento en la respuesta inflamatoria y una disminución en la calidad de vida de los pacientes con CD. Estas diferencias en los niveles de citocinas no estaban relacionadas con el estado de los anticuerpos contra la CD, lo que sugiere que el SII, en la CD, está relacionado con un proceso inflamatorio diferente al que es relevante para la CD.

Regulatory effect of Di'ao Xinxuekang on TLR4/MyD88/NF-κB signaling pathway in atherosclerotic rats / 中国中药杂志

The aim of this paper was to observe the effect of Di'ao Xinxuekang(DXXK) on TLR4/MyD88/NF-κB signaling pathway in atherosclerotic rats, and to explore its anti-atherosclerotic mechanism. Sixty SD rats were randomly divided into normal group, model group, atorvastatin group(4.0 mg·kg~(-1)), and DXXK groups(100, 30, 10 mg·kg~(-1)), with 10 rats in each group. The atherosclerosis model was induced by high fat diet plus vitamin D_2. Experimental drugs were administered intragastrically once daily for 8 weeks starting from the 9 th week. Biochemical analyzers were used to detect levels of triglyceride(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) in blood lipid. The levels of serum tumor necrosis factor(TNF)-α, interleukin(IL)-6 and IL-1β were detected by ELISA. Pathological changes of aortic tissues were observed by using Sudan Ⅳ and HE staining. The mRNA and protein expressions of TLR4, MyD88 and NF-κB p65 in aortic tissues were detected by RT-PCR and Western blot, respectively. As compared with the model group, TC, TG, and LDL-C levels in serum were significantly decreased, HDL-C content was significantly increased, and levels of TNF-α, IL-6, and IL-1β in serum were significantly decreased in atorvastatin group and DXXK high and middle dose groups. Aortic lesions in atorvastatin group and DXXK group were significantly improved, and the mRNA and protein expressions of TLR4, MyD88, NF-κB p65 in the aorta were decreased. DXXK has a preventive and therapeutic effect on atherosclerosis in rats, and its mechanism may be related to inhibiting inflammatory reaction by regulating TLR4/MyD88/NF-κB signal transduction, thereby inhibiting the progression of atherosclerosis.

Comparisons of clinical characteristics and prognosis between patients with primary and secondary thyroid lymphoma / 中华血液学杂志

Objective: To compare clinical characteristics and prognosis between patients with primary (PTL) and secondary thyroid lymphoma (STL) . Methods: A retrospective analysis was performed on 46 patients with thyroid lymphoma (PTL 19, STL 27) from January 2002 to October 2018. Results: ①PTL group included 4 males and 15 females, with a median age of 57 years. The STL group included 10 males and 17 females, with a median age of 61 years. Diffuse large B-cell lymphoma (DLBCL) was the main pathological subtype in both PTL and STL groups, with 14 cases (73.7%) and 20 cases (74.1%) respectively. In terms of clinical manifestations, goiter was the most common symptom in PTL patients 100.0% (19/19) , while 29.6% (8/27) STL had goiter (P<0.001) . The incidences of increased thyroglobulin antibody (TRAb) /thyroid peroxidase antibody (TPO) were 81.3% (13/16) in PTL group and 43.8% (7/16) in STL group (P=0.028) respectively. Concerning the clinical features of patients, only two PTL patients (10.5%) with advanced Ann Arbor stage (Ⅲ/Ⅳ) , while 21 (77.8%) STL experienced advanced Ann Arbor stage (P<0.001) . Elevated serum β(2)-MG were appeared in 1 (7.1%) PTL and 9 (47.4%) STL patients (P=0.013) , and advanced IPI score (3-5) was more common in STL than PTL (59.3% vs 5.3%, P<0.001) . ②Among the 17 PTL patients who received treatments, 15 (88.2%) achieved remission; as for STL patients received treatments, 23/25 (92.0%) were in remission. The 5-year overall survival (OS) rates of PTL (n=17) and STL groups (n=25) were (87.4±8.4) % and (70.0±13.1) % (P=0.433) respectively. ③The 5-year OS rate in 41 patients with B-cell thyroid lymphoma was (81.1±7.5) %. Univariate analysis showed that IPI score of 3-5 (P=0.040) and high level of serum IL-8 (P=0.022) were significantly associated with poor outcome. Conclusion: DLBCL was the most common subtype in both PTL and STL, and goiter was the major symptom in PTL. IPI score of 3-5 and high level of serum IL-8 were unfavorable prognostic factors for patients with B-cell thyroid lymphoma.

Inflammatory biomarkers responses after acute whole body vibration in fibromyalgia

The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines, soluble tumor necrosis factor receptors (sTNFr1, sTNFr2), and brain-derived neurotrophic factor (BDNF) were determined by enzyme-linked immunosorbent assay. Oxygen consumption (VO2) was estimated by a portable gas analysis system, heart rate (HR) was measured using a HR monitor, and perceived exertion (RPE) was evaluated using the Borg scale of perceived exertion. Acutely mild WBV increased VO2 and HR similarly in both groups. There was an interaction (disease vs vibration) in RPE (P=0.0078), showing a higher RPE in FM compared to HW at rest, which further increased in FM after acute WBV, whereas it remained unchanged in HW. In addition, there was an interaction (disease vs vibration) in plasma levels of adiponectin (P=0.0001), sTNFR1 (P=0.000001), sTNFR2 (P=0.0052), leptin (P=0.0007), resistin (P=0.0166), and BDNF (P=0.0179). In conclusion, a single acute session of mild and short WBV can improve the inflammatory status in patients with FM, reaching values close to those of matched HW at their basal status. The neuroendocrine mechanism seems to be an exercise-induced modulation towards greater adaptation to stress response in these patients.

Local and systemic effects of fibrin and cyanoacrylate adhesives on lung lesions in rabbits

OBJECTIVES: Tissue adhesives can be used to prevent pulmonary air leaks, which frequently occur after lung interventions. The objective of this study is to evaluate local and systemic effects of fibrin and cyanoacrylate tissue adhesives on lung lesions in rabbits. METHODS: Eighteen rabbits were submitted to videothoracoscopy + lung incision alone (control) or videothoracoscopy + lung incision + local application of fibrin or cyanoacrylate adhesive. Blood samples were collected and assessed for leukocyte, neutrophil and lymphocyte counts and interleukin-8 levels preoperatively and at 48 hours and 28 days post-operatively. After 28 days, the animals were euthanized for gross examination of the lung surface, and lung fragments were excised for histopathological analysis. RESULTS: Fibrin and cyanoacrylate produced similar adhesion scores of the lung to the parietal pleura. Microscopic analysis revealed uniform low-cellular tissue infiltration in the fibrin group and an intense tissue reaction characterized by dense inflammatory infiltration of granulocytes, giant cells and necrosis in the cyanoacrylate group. No changes were detected in the leukocyte, neutrophil or lymphocyte count at any time-point, while the interleukin-8 levels were increased in the fibrin and cyanoacrylate groups after 48 hours compared with the pre-operative control levels (p<0.01). CONCLUSION: Both adhesive agents promoted normal tissue healing, with a more pronounced local inflammatory reaction observed for cyanoacrylate. Among the serum markers of inflammation, only the interleukin-8 levels changed post-operatively, increasing after 48 hours and decreasing after 28 days to levels similar to those of the control group in both the fibrin and cyanoacrylate groups.

Association between the clinical severity of oral lichen planus and anti-TPO level in thyroid patients

Abstract This study considered a possible relationship between the severity of oral lichen planus (OLP), serum anti-TPO autoantibodies (TPOAb) titer and thyroid disease in OLP patients. Forty-six OLP patients with positive TPOAb results (> 35 IU/ml) who had also been diagnosed with thyroid disease were included in the study group. The control group consisted of 46OLP patients with no thyroid disease. The study and control groups (92) were divided to two subgroups of erosive OLP (EOLP) and non-erosive OLP (NEOLP). Serum TPOAb levels and IL-8 (to measure OLP severity) were evaluated using the independent t-test, chi-square and conditional logistic regression analysis (α = 0.05). A significant positive correlation was found between serum IL-8 and TPOAb levels in the study group (r = 0.783; p = 0.001). The positive blood levels of TPOAb were significantly associated with an increased risk of EOLP (OR = 4.02 at 95%CI; 1.21–13.4; p = 0.023). It is possible to used positive serum TPOAb levels in patients with OLP as in indicator of possible undetected thyroid disorders in those patients. Because erosive OLP has been associated with TPOAb in thyroid patients, it may be useful to determine TPOAb levels of such patients to diagnose a possible undetected thyroid disorders and follow-up for malignancy.

Association of autophagy related gene polymorphisms with neutrophilic airway inflammation in adult asthma

BACKGROUND/AIMS: Role of autophagy in neutrophil function and the association of autophagy and autophagy related (ATG) gene polymorphisms with asthma susceptibility were suggested. In this study, we investigated the genetic association of ATG5 and ATG7 polymorphisms with asthma risk, severity and neutrophilic airway inflammation. METHODS: We recruited 408 asthma patients and 201 healthy controls. Sputum neutrophil counts were determined by H&E staining. Serum interleukin 8 (IL-8) levels were measured by enzyme-linked immunosorbent assay (ELISA). Genetic polymorphisms of ATG5 (-769T>C, -335G>A, and 8830C>T) and ATG7 (-100A>G and 25108G>C) were genotyped. The functional activities of ATG5 -769T>C and -335G>A variants were investigated by luciferase reporter assays. RESULTS: No associations of ATG5 and ATG7 polymorphisms with asthma susceptibility and severity were found. ATG5 -769T>C and -335G>A were in complete linkage disequilibrium. In the asthma group, GA/AA genotypes at ATG5 -335G>A were associated with higher neutrophil counts in sputum (p T associated with lower FEV1% predicted value (p G and 25108G>C were significantly associated with high serum levels of IL-8 (p < 0.05 for both variants). CONCLUSIONS: Genetic polymorphisms of ATG5 and ATG7 could contribute to neutrophilic airway inflammation in the pathogenesis of adult asthma.

Comparative Analysis of Liver Injury-Associated Cytokines in Acute Hepatitis A and B

PURPOSE: Acute hepatitis A (AHA) and acute hepatitis B (AHB) are caused by an acute infection of the hepatitis A virus and the hepatitis B virus, respectively. In both AHA and AHB, liver injury is known to be mediated by immune cells and cytokines. In this study, we measured serum levels of various cytokines and T-cell cytotoxic proteins in patients with AHA or AHB to identify liver injury-associated cytokines. MATERIALS AND METHODS: Forty-six patients with AHA, 16 patients with AHB, and 14 healthy adults were enrolled in the study. Serum levels of 17 cytokines and T-cell cytotoxic proteins were measured by enzyme-linked immunosorbent assays or cytometric bead arrays and analyzed for correlation with serum alanine aminotransferase (ALT) levels. RESULTS: Interleukin (IL)-18, IL-8, CXCL9, and CXCL10 were significantly elevated in both AHA and AHB. IL-6, IL-22, granzyme B, and soluble Fas ligand (sFasL) were elevated in AHA but not in AHB. In both AHA and AHB, the serum level of CXCL10 significantly correlated with the peak ALT level. Additionally, the serum level of granzyme B in AHA and the serum level of sFasL in AHB correlated with the peak ALT level. CONCLUSION: We identified cytokines and T-cell cytotoxic proteins associated with liver injury in AHA and AHB. These findings deepen the existing understanding of immunological mechanisms responsible for liver injury in acute viral hepatitis.

Serum Levels of IL-8 and ICAM-1 as Biomarkers for Progressive Massive Fibrosis in Coal Workers' Pneumoconiosis

Coal workers' pneumoconiosis (CWP) is characterized as a chronic inflammation of the lung associated with activation of macrophages and endothelial cells in the lung. The aim of the present study was to compare the levels of serum interleukin-8 (IL-8), macrophage inflammatory protein-1alpha (MIP-alpha), and intercellular adhesion molecule-1 (ICAM-1) as biomarkers for progressive massive fibrosis (PMF) in 106 subjects (27 non-CWP and 79 CWP patients). The levels of serum IL-8 (P<0.001) and ICAM-1 (P=0.001) of subjects with PMF were higher than those of non-CWP subjects. The IL-8 levels of PMF subjects were also higher than those of simple CWP subjects (P=0.003). Among the subjects without PMF, IL-8 levels in the subjects with International Labour Organization (ILO) category II or III were higher than those in the subjects with ILO category 0 (P=0.006) and with category I (P=0.026). These results suggest that high serum levels of IL-8 and ICAM-1, which are important as neutrophil attractants and adhesion molecules, are associated with PMF.

Serum levels of interleukin-7 and interleukin-8 in head and neck squamous cell carcinoma.

Background: The aim of this study was to investigate the association of head and neck squamous cell carcinoma (HNSCC) with serum levels of interleukin-7 (IL-7) and IL-8, the two cytokines whose associations with HNSCC need more clarifications. Materials and Methods: Commercial enzyme-linked immunosorbent assay kits were used for the quantification of the cytokines. Sera were collected from 48 untreated patients (36 men and 12 women; mean age: 52.7 ± 9.8 years) and 34 healthy donors (26 men and 8 women; mean age: 53.1 ± 9.0 years). Results: Serum IL-8 level was neither significantly different between HNSCC patients and control individuals nor associated with smoking status, gender, age, tumor location, tumor grade, and stage of the patients (P > 0.05). Regarding IL-7, all control individuals had serum levels below the sensitivity of the kit (3 pg/ml), but nine patients had detectable levels, and that the mean serum IL-7 was significantly higher in the patients compared to the controls (P = 0.008). Conclusions: Serum IL-8 level is not significantly associated with HNSCC. With the sensitivity of the kit we employed, it seems that serum IL-7 levels are specifically elevated in HNSCC patients compared to healthy individuals. Data from other independent studies are required to clarify the possible employment of IL-7 as an HNSCC biomarker.

Assessment of serum interleukin-8 as a sensitive serological marker in monitoring the therapeutic effect of levamisole in recurrent aphthous ulcers: A randomized control study.

Aim: The study was designed to evaluate the serum interleukin‑8 (IL‑8) levels in patients with recurrent aphthous ulcer (RAU) and monitor the immunomodulation and altered IL‑8 levels by levamisole before therapy and after levamisole therapy. Materials and Methods: This study was carried as a randomized case‑control study involving a study group of 30 patients diagnosed as RAUs and given levamisole (vermisole 150 mg, od for 1st 3 days of 3 weeks in a month and for 3 months with a gap of 1 week) and these patients were recalled after 3 months and were subjected for estimation of serum IL‑8 levels. Control group had 20 age and sex matched individuals with no systemic illness and were not given any levamisole. Good compliance was reported at the end of the study. Results: Mild gastric irritation was reported and when severe it was managed by H1 blocker. Patients were reviewed after 3 months. The follow‑up data at each visit with respect to each other and to base‑line values was calibrated using a Students t‑test. Highly significant comparisons were obtained in the serum IL‑8 between study and control groups before the onset of levamisole (t = 6.53, P ≤ 0.001). IL‑8 levels reduced by 72% after levamisole was instituted in RAU patients and comparison was highly significant for before and after levamisole onset (t = 5.54, P ≤ 0.001). Conclusion: This study points to the effectiveness of levamisole as an effective adjunct therapy in the routine management of RAU.

Role of cerebrospinal fluid il-8 as a marker for differentiation between acute bacterial and aseptic meningitis

No doubt, the distinguishing between bacterial and aseptic meningitis in the emergency department could help to limit unnecessary antibiotic use and hospital admissions. This study evaluated the role of cerebrospinal fluid IL-8 in differentiating acute bacterial meningitis [ABM] from aseptic meningitis [AM]. A total of 80 hospitalized patients with clinical presentations of suspected acute meningitis were subjected to estimation of IL-8 CSF concentrations. The results showed that CSF IL-8 levels were higher in acute bacterial meningitis than in aseptic ones [p <0.05]. The best cut-off value of CSF IL8 for early diagnosis of bacterial meningitis was 3.6ng/ml with a sensitivity of 82.5% and a specificity of 85.0%

Quantitative Analysis of Tissue Injury after Minimally Invasive Total Hip Arthroplasty

BACKGROUND: We intended to clarify the hypothesis that minimally invasive total hip arthroplasty (MI-THA) leads to less tissue damage and inflammatory response than does conventional total hip arthroplasty (C-THA). METHODS: We performed 30 cases of THA between September 2005 and May 2006 and evaluated these cases prospectively. We chose 15 MI-THA cases for the study group and another 15 C-THA cases for the control group. We checked skeletal muscle marker enzymes, such as serum creatinine kinase and aldolase, the pro-inflammatory cytokines, interleukin (IL)-6 and 8, and the anti-inflammatory cytokines, IL-10 and IL-1 receptor antagonist (ra) the day before surgery and at postoperative days 1, 7, and 14. RESULTS: On postoperative days 1 and 3, the study group showed significantly lower serum creatinine kinase, IL-6, IL-10, and IL-1ra values than those in the control group. Additionally, IL-8 was significantly lower on day 7 after surgery. CONCLUSIONS: These data show that MI-THA decreased the release of muscle marker enzymes due to tissue damage immediately after surgery and minimized the inflammatory response related to the surgery during the early postoperative period.

Effect of methotrexate on serum levels of IL-1alpha and IL-8 in rheumatoid arthritis

Rheumatoid arthritis is a chronic systemic inflammatory disease affects many tissues and organs, but principally attacks flexible [synovial] joints. Methotrexate is the most commonly used disease-modifying antirheumatic drug for the treatment of rheumatoid arthritis. The aim of this study was to evaluate the effect of methotrexate on serum levels of IL-1alpha and IL-8 in rheumatoid arthritis. Blood samples were collected from 50 patients with rheumatoid arthritis [25 patients without treatment and 25 patients are received methotraxate] and from 30 healthy age and sex matched individuals served as controls. Serum IL-1alpha and IL-8 were measured by means of enzyme-linked immune-sorbent assay. The present results showed that serum levels of IL-1alpha and IL-8 were significantly higher in RA patients than in healthy controls [P<0.01], furthermore, level of IL-1alpha was significantly decrease in patients treated with methotraxate as compared to those patients who have received no treatment [P<0. 01]. On the other hand serum level of IL-8 didn't showed any significant differences between patients treated with methotraxate and those patients without treatment [P>0. 05]. These finding demonstrate that methotrexate turns out to be a good inhibitor for IL-alpha production. In addition, IL-1alpha and IL-8 may have a significant role in the pathogenesis of rheumatoid arthritis, and could be use as.

Evaluation of the role of CXCL8 and NOx in pediatric type 1 diabetes mellitus

Genetic and environmental factors may play a role in the etiology of type 1diabetes [T1D] but a well-accepted view is that autoimmunity is the predominant effector. The aim of this study is to investigate the profile and the relationships between interleukin [IL, CXCL] -8 and nitric oxide metabolite [NOx] in T1D and to reveal their possible role in the development and progression of the disease and its complications. Twenty children with Type 1 diabetes [T1D] were enrolled for the study and compared to twenty healthy age and gender matched non-diabetic controls. The data revealed that children with T1D established high glycated hemoglobin [HbA1c%] values versus the control group [P<0.0001]. Significantly higher serum CXCL-8 concentration [23.54 +/- 11.92pg/ml] was detected in T1D children versus the control group [5.69 +/- 1.67pg/ml]. On the other hand, serum nitric acid metabolite [NOx] showed a significant reduction in the T1D children [2.38 +/- 1.14 mmol/l] compared to the control group [4.63 +/- 1.2 mmol/l]. Correlation analysis showed positive correlation between CXCL-8 with duration of the diabetes and with HbA1c. It could be concluded that CXCL-8 and NO may play important roles in the pathophysiology and progression of T1D with increased possibility to develop premature atherosclerosis which should be considered in the development of new strategies for monitoring the disease as well as for developing effective preventive and therapeutic interventions

[ effects of docosahexaenoic acid [DHA] on helicobacter pylori eradication, some serum inflammatory factors and total antioxidant capacity]

As regard to high prevalence of Helicobacter pylori infection and complications of it's persistence, as well as anti-bacterial activity against of Helicobacter pylori and anti-inflammatory properties of omega-3 fatty acids, this study was conducted to evaluate the effects of supplementation with Docosahexaenoic Acid [DHA] on the eradication of Helicobacter pylori infection, some serum inflammatory markers and total antioxidant capacity. In a double-blind, placebo-controlled clinical trial, 66 H. pylori positive patients [33 in the intervention group and 33 in the control group], along with tetradrugs H. pylori eradication regimen, randomly received daily two grams morDHA supplement or Medium Chain Triglyceride [MCT] oil as placebo for 12 weeks. Dietary intake data was collected by 24 hour food recall and analyzed by Nutritionist IV software. Sampling from fasting blood and measuring weight, height, body mass index [BMI] and level of physical activity were done at the first and the end of the study. As well as, eradication test of the infection was performed for all patients at the end of the intervention. Eradication rate of the infection, the level of interleukin-6 [IL-6], high sensitivity C-reactive protein [hs-CRP] and total antioxidant capacity [TAC] didn't have significant difference between two groups at the end of the study [P>0.05], while the level of interleukin-8 [IL-8] was different between two groups [P=0.008]. Difference of the concentration between the beginning and the end of the study was not significant in any factors between two groups [P>0.05]. Intake of morDHA supplement didn't have significant effect on the eradication of H. pylori, serum levels of IL-6, hs-CRP and TAC, while it was effective on the level of IL-8.

[ effect of tomato juice on serum concentrations of IL-6, IL-8, CRP and TNF-alpha of over-weight or obese girl students of Tehran University of Medical Science]

Tomatoes are the richest source of lycopene, a potent antioxidant. Tomato products improve antioxidant defenses and reduce the risk of inflammatory diseases, at least partly due to the presence of lycopene. Lycopene, as an anti-inflammatory agent, prevents the production of inflammatory cytokines. Obesity is a chronic inflammatory condition in which the increased level of body fat leads to an increase in circulating inflammatory mediators. We hypothesized that the consumption of a lycopene-rich food would reduce inflammation in people with overweight or obesity. One hundred and six overweight or obese female students of Tehran University of Medical Sciences were enrolled and randomly allocated to an intervention group [n=53] or a control group [n=53], consuming 330 ml/day of tomato juice or water respectively, for 20 days. At baseline and day 20, serum concentrations of interleukin-6, interleukin-8, tumor necrosis factor-alpha and high sensitivity C-reactive protein were analyzed by ELISA and compared between groups. Serum concentrations of interleukin-8 and tumor necrosis factor-alpha decreased significantly in the intervention group compared to the control group and compared to the baseline. Subgroup analysis indicated that this effect was confined to subjects who were overweight. Among obese subjects, serum interleukin-6 concentration was decreased in the intervention group compared to the control group, with no observed differences in interleukin-8 and tumor necrosis factor-alpha. Tomato juice reduces inflammation in overweight and obese females. Thus, increasing tomato intake may provide a useful approach for reducing the risk of inflammatory diseases such as cardiovascular disease and diabetes, associated with obesity

Changes in the Levels of Interleukins 6, 8, and 10, Tumor Necrosis Factor Alpha, and Granulocyte-colony Stimulating Factor in Korean Burn Patients: Relation to Burn Size and Postburn Time

BACKGROUND: Major burn injury induces an inflammatory response that is accompanied by the release of various cytokines. We investigated the gradual changes in the levels of pro-inflammatory and anti-inflammatory cytokines following burn injury and determined the relationship between these levels and burn size in adult Korean patients with burn injury. METHODS: Blood samples from 9 healthy controls and 60 Korean burn patients were collected on days 1, 3, 7, 14, and 21 after burn injury, and concentrations of interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF)-alpha, and granulocyte-colony stimulating factor (G-CSF) were measured. Burn patients were divided into 3 groups according to burn size (15-30%, 31-50%, >50% total body surface area), and the concentrations of the cytokines were compared between these groups and the control group over 3 weeks. RESULTS: Compared to their levels in controls, IL-6, IL-8, IL-10, TNF-alpha, and G-CSF levels in burn patients were significantly higher during the observation period. Median concentrations of IL-8, IL-10, and G-CSF at each time point increased with burn size, although peak levels and time to peak levels of these cytokines differed from patient to patient. CONCLUSIONS: These findings indicate that IL-6, IL-8, IL-10, TNF-alpha, and G-CSF are important mediators in inflammatory changes after burn injury; however, various factors, including burn size, may influence the concentrations of these cytokines.
