目的探讨白细胞介素-5(IL-5)、可溶性白细胞介素-2受体(sIL-2R)、一氧化氮(N())及嗜酸性粒细胞(EOS)在哮喘发病中的意义。方法对治疗前后的急性发作期、稳定期哮喘组及对照组血清II-5、sIL-2R和NO水平及EOS计数进行了研究。结果哮喘急性发作组血清IL-5、sIL-2R、NO及EOS水平均明显高于哮喘缓解期组与对照组。哮喘发作期IL-5与EOS呈显著正相关。哮喘急性发作期组治疗后sIL-2R及NO水平较治疗前显著降低，IL-5与EOS水平下降但无统计学意义。结论血清IL-5、sIL-2R、NO及EOS水平升高，与哮喘发作密切相关。

晚期日本血吸虫病患者血清可溶性白细胞介素-2受体的研究

采用双抗体夹心ELISA法,检测47例晚期日本血吸虫病患者血清可溶性白细胞介素-2受体(sIL-2R),同时用间接免疫荧光法测定其外周血单个核细胞(PBMCs)膜IL-2受体(mIl-2R)的表达水平。结果表明晚血患者血清sIL-2R较正常人明显增高,而mIl-2R表达明显低下(P<0.01),其sIL-2R水平与mIl-2R表达呈负相关(r=-0`62,P<0.01).血清sIL-2R高低与COPT阳性与否无关,说明患者血清sIL-2R高低与病原体本身无直接关系,而与患者是否伴腹水有关,提示sIL-2R水平与疾病进展程度有关。观察患者血清sIL-2R的高低可作为疾病病程的监测指标。

Soluble interleukin-6 receptor in rheumatoid arthritis

Abstract

To investigate the pathophysiologic role of soluble interleukin-6 receptor (sIL-6R) in patients with rheumatoid arthritis (RA), serum sIL-6R levels were measured in 15 RA patients and 15 healthy control subjects using a sandwich enzyme-linked immunosorbent assay. Correlation analysis was performed between sIL-6R levels and clinical variables such as joint score, Lansbury’s index, C-reactive protein and platelet counts. Levels of sIL-6R and IL-6 were also measured in paired samples of serum and synovial fluid obtained at the same time from nine RA patients. Serum sIL-6R levels in RA patients (153.9±56.9 ng/ml) were significantly higher than those of control subjects (115.1±19.1 ng/ml; P<0.05). However, sIL-6R levels did not correlate with any clinical characteristic of RA. sIL-6R was detectable in synovial fluid, but was invariably lower than in serum, in contrast to IL-6 (i.e. much higher in synovial fluid). It correlated neither with total cell nor neutrophil number in synovial fluid. Serum C-reactive protein levels were significantly correlated with IL-6 in synovial fluid, but not with sIL-6R in synovial fluid. These results indicate that serum sIL-6R levels are increased in RA patients. High levels of serum sIL-6R did not seem to be derived from the site of local inflammation. The readily detectable sIL-6R in synovial fluid may co-operate with IL-6 in the pathogenesis of synovitis in RA.

Circulating levels of interleukin-6, its soluble receptor and interleukin-6/interleukin-6 receptor complexes in patients with type 2 diabetes mellitus

We evaluated the relationship between plasma fibrinogen concentration and the serum levels of interleukin-6 (IL-6), its soluble receptor, and their complex in patients with type 2 diabetes mellitus. The study comprised 57 patients with type 2 diabetes and 15 normal healthy controls. Serum levels of IL-6, soluble IL-6 receptor (IL-6R), and circulating IL-6/IL-6R complex were determined by enzyme-linked immunosorbent assays. Correlations between the different study parameters and serum IL-6, IL-6R, or IL-6/IL-6R complex levels were determined by multiple linear regression analysis. Any association between the different study parameters and the serum levels of IL-6, IL-6R, or IL-6/IL-6R complex were determined by stepwise linear regression analysis. The serum IL-6 level in diabetic subjects was significantly higher than in normal healthy controls (3.48 ± 3.29 pg/ml vs 0.784 ± 0.90 pg/ml, mean ± SD, respectively, P = 0.0001). The specific optical density of the serum IL-6/IL-6R complex in diabetic patients was also significantly higher than in normal healthy controls, although there was no significant difference in the serum IL-6R level between diabetic patients and controls. The serum IL-6 concentration was correlated significantly with the HbA_1C level (β = 0.58, P = 0.04) by multiple regression analysis. Stepwise regression analysis revealed that the levels of serum IL-6 (F = 8.251), HbA_1C (F = 1.08), and serum urea nitrogen (F = 5.603) were associated with the plasma fibrino gen concentration. These results suggest that hyperglycaemia and increased levels of serum IL-6 can increase the plasma fibrinogen concentration, one of the known risk factors for atherosclerosis in patients with type 2 diabetes mellitus.

Serum soluble interleukin-2 receptor levels in patients with chronic hepatitis B virus infection and its relation with anti-HBc

AIM:To investigate the relationship between serumsoluble interleukin-2 receptor(sIL-2R)level and anti-HBcin patients with chronic hepatitis B virus(HBV)infection.METHODS:Sera from 100 patients with chronic HBVinfection and 30 healthy controls were included in thisstudy.The patients were divided into group A[HBsAg( ),HBeAg( )and anti-HBc( ),n=50]and group B[HBsAg( ),HBeAg( )and anti-HBc(-),n=50].sIL-2R levelswere determined using ELISA.HBV DNA and alanineaminotransferase(ALT)were also detected.RESULTS:Serum sIL-2R levels were significantly higherin patients with chronic HBV infection than in healthycontrols.Moreover,serum sIL-2R levels were significantlyhigher in patients with HBsAg( ),HBeAg( )and anti-HBc( )(976.56±213.51×10~3 U/L)than in patients withHBsAg( ),HBeAg( )and anti-HBc(-)(393.41±189.54×10~3 U/L,P<0.01).A significant relationship was foundbetween serum sIL-2R and ALT levels(P<0.01)inpatients with chronic HBV infection,but there was nocorrelation between sIL-2R and HBV DNA levels.Theanti-HBc status was significantly related to the age ofpatients(P<0.01).CONCLUSION:The high sIL-2R level is related topositive anti-HBc in chronic hepatitis B patients.Positiveanti-HBc may be related to T-lymphocyte activation andnegative anti-HBc may imply immune tolerance in thesepatients.     

Soluble interleukin-2 receptor in sera and synovial fluids of rheumatoid patients: correlations with disease activity

The measurement of serum soluble interleukin-2 receptor (sIL-2R), a sensitive marker of lymphocyte activation, has been proposed as an indicator of disease activity and outcome in patients with inflammatory diseases characterized by the activation of immune cells. Serum sIL-2R levels have been reported higher in rheumatoid patients than in controls. Using an enzyme-linked immunoabsorbent assay (ELISA), we evaluated soluble IL-2R levels in the serum of 34 patients with RA and in the synovial fluid of 25 of these patients and we compared it with levels found in the serum of 13 healthy controls. Serum sIL-2R levels were significantly elevated in RA patients compared with the healthy agematched control group (P<0.005). The mean level of soluble IL-2R in synovial fluids was significantly higher than the mean sera levels in RA patients (P<0.0001). Moreover, we examined the correlation between serum and synovial fluid sIL-2R levels and disease activity measures. Serum sIL-2R correlated only with ESR (P<0.04). The synovial fluid sIL-2R correlated with ESR (P<0.02) and a visual analogue scale (VAS) pain score (P<0.04). Both serum and synovial fluid sIL-2R levels correlated with the chronic arthritis systemic index (CASI; P<0.04 and P<0.005, respectively). Our data suggested that in RA the measurement of sIL-2R may certainly mirror the degree of chronic inflammation and the continuous activation of the immune cells in the joint, although the role of this molecule in the immune response is still unclear.     

血液透析患者sIL－2R、IL－6变化与淫羊藿的免疫调节作用

用ＥＬＩＳＡ方法和白细胞介素６（ＩＬ－６）依赖细胞株ＭＴＴ掺入法对血液透析患者循环可溶性ＩＬ－２受体（ｓＩＬ－２Ｒ）和ＩＬ－６水平进行了检测，并同时观察了用中药淫羊藿治疗同一血透患者３个月前、后上述指标的变化。结果证实血液透析患者ｓＩＬ－２Ｒ水平明显增高（Ｐ＜０．０１），ＩＬ－６水平明显降低（Ｐ＜０．０１），用淫羊藿治疗后ｓＩＬ－２Ｒ及ＩＬ－６水平可调整至正常水平。由此说明血液透析患者存在免疫功能的降低，中药淫羊藿的调节作用是有效的。
