O2-, H2O2 and OH. We reported increased tumour necrosis factor-α, soluble interleukin-2 receptor, interleukin-6, interleukin-8 and NO in active BD. As there is a relation between cytokines, T cells and oxidative stress in inflammatory diseases, this study further evaluated: (1) plasma AD activity and its correlation with acute phase reactants; (2) thiobarbituric acid-reactive substances (TBARS) as an indicator for lipid peroxidation; and (3) antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and catalase in patients with BD. The effect of disease activity and correlations between the measured parameters were explored.Methods: A total of 35 active (n=17) or inactive (n=18) patients with BD (16 men, 19 women) satisfying International Study Group criteria, and 20 age-matched and sex-matched controls (nine men, 11 women) were included in this cross-sectional case-control study. AD and TBARS were measured in plasma, catalase in red blood cells (RBC), and SOD and GSHPx in both plasma and RBC in both groups. Acute phase reactants (α1, α2, neutrophils, erythrocyte sedimentation rate) were used to classify patients as active or inactive.Results: Plasma AD (mean±standard error of the mean, 36.1±0.7 U/l) and TBARS (4.2±0.1 nmol/ml) levels were significantly (for each, P<0.001) higher in BD than in controls (24.1±0.8 U/l and 1.6±0.1 nmol/ml, respectively). RBC catalase activity was significantly (P<0.001) lower in BD than in controls (120.9±3.8 versus 160.3±4.1 k/g haemoglobin). SOD and GSHPx activities were significantly lower in both plasma and erythrocytes of patients with BD than in controls (plasma SOD, 442.4±8.6 versus 636.4±9.2 U/ml, P<0.001; RBC SOD, 3719.2±66.0 versus 4849.7±49.0 U/g haemoglobin, P<0.001; plasma GSHPx, 73.1±1.5 versus 90.6±2.9 U/ml, P<0.001; RBC GSHPx, 600.7±8.0 versus 670.6±10.1 U/g haemoglobin, P<0.001). Active BD patients had significantly lower antioxidant enzymes (except RBC catalase) and higher AD and TBARS levels than inactive subjects (for each, P<0.01). When considering all BD patients, a significant positive correlation was present between AD and TBARS (P<0.001) whereas both AD and TBARS were negatively correlated with antioxidant enzymes (for each, P<0.05).Conclusions: AD and lipid peroxidation are increased and associated with defective antioxidants in BD, suggesting interactions between activated T cells and neutrophil hyperfunction. Measures of pro-oxidative stress and antioxidative defence with AD activity as an indicator of T-cell activation can be considered as significant supportive diagnostic indicators, especially in active disease. In addition, strengthening the antioxidant defence may contribute to treatment modalities."> 在Behçet的疾病患者中,腺苷脱氨酶活性增加并与过氧化氢酶、超氧化物歧化酶和谷胱甘肽过氧化物酶呈负相关:原始贡献/临床和实验室调查 - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

在Behçet的疾病患者中,腺苷脱氨酶活性增加并与过氧化氢酶、超氧化物歧化酶和谷胱甘肽过氧化物酶呈负相关:原始贡献/临床和实验室调查

摘要

目的:Behçet的疾病(BD)是一种炎性血管炎,伴有免疫、内皮和中性粒细胞改变。腺苷脱氨酶(Adenosine deaminase, AD)是t细胞活化的标记物,与中性粒细胞产生活性氧并产生NO有关 O 2 - H2O2噢,.我们报告肿瘤坏死因子-α、可溶性白细胞介素-2受体、白细胞介素-6、白细胞介素-8和NO升高炎症性疾病中细胞因子、T细胞与氧化应激之间存在相关性,本研究进一步评估:(1)血浆AD活性及其与急性期反应物的相关性;(2)硫代巴比妥酸反应物质(TBARS)作为脂质过氧化指标;(3)抗氧化酶超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSHP)x)和过氧化氢酶在双相障碍患者中的作用,探讨疾病活动性的影响及测量参数之间的相关性。方法:总共有35个 n 17 或不活跃 n 18 本横断面病例对照研究纳入符合国际研究组标准的BD患者(16男19女)和20名年龄和性别匹配的对照(9男11女)。测定血浆AD和TBARS,红细胞过氧化氢酶,SOD和GSHPx在两组的血浆和红细胞中急性相反应物12(中性粒细胞,红细胞沉降率)来区分活跃和不活跃的患者。结果:血浆AD(平均值±标准误差平均值,36.1±0.7 U/l)和TBARS(4.2±0.1 nmol/ml)水平均有显著性差异( P < 0.001 (24.1±0.8 U/l和1.6±0.1 nmol/ml)。红细胞过氧化氢酶活性显著 P < 0.001 BD低于对照组(120.9±3.8 vs 160.3±4.1 k/g血红蛋白)。SOD和GSHPx与对照组相比,BD患者的血浆和红细胞活性均显著降低(血浆SOD, 442.4±8.6 vs 636.4±9.2 U/ml; P < 0.001 ;红细胞SOD, 3719.2±66.0 vs 4849.7±49.0 U/g血红蛋白, P < 0.001 ;等离子体GSHPx, 73.1±1.5 vs 90.6±2.9 U/ml, P < 0.001 ;加拿大皇家银行GSHPx, 600.7±8.0 vs 670.6±10.1 U/g血红蛋白, P < 0.001 ).活动期双相障碍患者的抗氧化酶(红细胞过氧化氢酶除外)明显低于非活动期受试者,AD和TBARS水平高于非活动期受试者(每个患者, P < 0.01 ).当考虑所有BD患者时,AD与TBARS之间存在显著正相关 P < 0.001 而AD和TBARS与抗氧化酶呈负相关(每一种, P < 0.05 ).结论:AD和脂质过氧化增加,并与BD中缺陷的抗氧化剂相关,提示活化的T细胞和中性粒细胞功能亢进之间存在相互作用。以AD活性作为t细胞活化指标的促氧化应激和抗氧化防御措施可被认为是重要的支持性诊断指标,特别是在活动性疾病中。此外,加强抗氧化防御可能有助于治疗方式。
