Clinical significance of serum IL-18 determination in rheumatoid arthritis

Interleukin (IL)-18 is a novel cytokine expressing at inflammatory lesion. In this study, to evaluate the clinical significance of IL-18 determination, we have examined serum IL-18, inflammation markers, sFas, and sFas-ligand concentrations in patients with rheumatoid arthritis(RA). Serum was obtained from 56 RA patients aged 35-74 years, 16 osteoarthritis (OA) patients aged 36-78 years and 178 healthy subjects aged 20-72 years and IL-18 was measured by ELISA. Serum IL-18 concentrations in RA (240.1 +/- 15.6 pg/ml, mean +/- SE) were significantly higher than OA (151.8 +/- 12.7 pg/ml, p < 0.005) and healthy controls(141.5 +/- 26.1 pg/ml, p < 0.001). Serum IL-18 levels were significantly increased in II to IV stages of RA (stage II; 218.6 +/- 31.2 pg/ml, stage III; 258.7 +/- 38.4 pg/ml, stage IV; 231.6 +/- 13.1 pg/ml) than those in OA. Furthermore, a positive correlation was observed between serum IL-18 concentration and serum Fas level in patients with RA (r = 0.472), whereas there was no significant correlation between serum IL-18 and sFas-ligand or other inflammatory markers (CRP, RF, CA-RF, IL-6, and IL-8). The present study showed that serum IL-18 level increased in RA, but it is unknown how IL-18 is involved in the pathogenesis of RA. Further study will be necessary to clarify the role of IL-18 in RA.     

类风湿关节炎患者血清可溶性髓样细胞触发受体-1、白介素-17水平分析

Association of increased serum IL-33 levels with clinical and laboratory characteristics of systemic lupus erythematosus in Chinese population

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by abnormal production of autoantibodies and proinflammatory cytokines. Although interleukin-33 (IL-33), a novel number of the IL-1 family, has been reported to have proinflammatory effects, the association of IL-33 with SLE has remained unknown. The aim of this study was to examine whether the serum IL-33 level is associated with SLE. A total of 70 patients with SLE were recruited. Sera from these patients were obtained at their visit and were compared to sera from 40 healthy controls or 28 patients with rheumatoid arthritis (RA) for IL-33 level. Furthermore, blood samples from patients with SLE were determined for various SLE-related laboratory variables, including blood routine, complements, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and some autoantibodies. Serum IL-33 level was significantly increased in patients with SLE, compared with healthy controls, but was lower than that with RA. In patients with SLE, most clinical and laboratory characteristics did not correlate with serum IL-33 levels, with exceptions of thrombocytopenia, erythrocytopenia, anti-SSB antibody, ESR, CRP and IgA. By Spearman’s correlation coefficient, patients with SLE showed close correlation of IL-33 with ESR, CRP and IgA, and by multivariate logistic regressions, patients with SLE showed significantly independent association of IL-33 with thrombocytopenia, erythrocytopenia and anti-SSB antibody. Our results suggest that IL-33 may play a role in acute phase of SLE, but it was not associated with course of the disease. Moreover, IL-33 may exert biologic effects on erythrocytes and platelets or their precursors in SLE.

类风湿关节炎患者血清和关节液细胞因子水平的变化及临床意义

目的探讨幼年类风湿关节炎(JRA)及类风湿关节炎(RA)患者IL-6、IL-8、sIL-2R和TNF-α等细胞因子(CK)水平的变化,及其与风湿活动的传统指标血沉(ESR)和C-反应蛋白(CRP)的相关性。方法采用夹心ELISA法,对30例JRA和34例RA患者的血清中,4例JRA、7例RA、6例骨性关节炎(OA)和9例半月板损伤(MT)患者的关节液中IL-6、IL-8、sIL-2R和TNF-α的水平进行检测。结果①30例JRA、34例RA患者血清IL-6和sIL-2R的水平与对照组相差非常显著(P〈0.01);30例JRA患者血清IL-8水平与对照组比较相差显著(P〈0.05)。②JRA全身型、少关节型患者血清IL-8、sIL-2R的水平和JRA多关节型患者血清IL-6的水平与对照组相差非常显著(P〈0.01)。③4例JRA及7例RA患者关节液sIL-2R的水平和RA患者关节液的IL-6水平与对照组相差显著(P〈0.05)。④JRA患者血清IL-6和sIL-2R的水平与ESR和CRP的变化呈明显的相关关系(r值分别为0.532和0.621)。结论①IL-6、sIL-2R的水平与JRA、RA病的活动性有关,是类风湿活动性的主要指标。②sIL-2R不仅参与JRA和RA的全身病理损伤,而且是引起关节局部损伤的主要CK,IL-6也参与JRA关节局部的病理损伤,在RA关节局部损伤似乎更为重要。③IL-8主要参与JRA的全身病理损伤,对关节局部病理损伤似乎并不重要。     

Quantitative solid phase fluorescence immunoassay of rheumatoid factor and C-reactive protein in active rheumatoid arthritis

A quantitative, semiautomated, solid-phase fluorescence immunoassay (FIA) has been developed for measuring rheumatoid factor (RF) and C-reactive protein (CRP). The correlation of the FIA measurement of RF and CRP with standard measurements in rheumatoid arthritis (RA) patients is not known. To determine the correlation of FIA with standard assay methods, RF and CRP levels were measured by both methods in 151 patients with active RA. RF levels measured by FIA correlated very closely with charcoal agglutination method (r2 = 0.890, P less than 0.0001). CRP levels by FIA correlated very closely with CRP levels by nephelometric method (r2 = 0.886, P less than 0.0001) and Westergren erythrocyte sedimentation rates (ESR) (r2 = 0.356, P less than 0.0001). A weak statistical correlation of RF, CRP, and ESR with some clinical variables of RA disease activity was demonstrated. Measurement of RF and CRP by FIA is similar to standard methods and offers no specific advantages in evaluating RA patients at a single evaluation.     

泌乳素促进类风湿关节炎患者外周血单个核细胞分泌白细胞介素-6

目的:探讨类风湿关节炎(RA)患者血清泌乳素(PRL)水平与疾病活动程度的关系,以及PRL促进外周血单个核细胞(PBMCs)分泌白细胞介素-6(IL-6)的机制。方法:收集我院2015年3月至9月40例初治RA患者临床及实验室资料。采用化学发光免疫分析法(CLIA)检测血清PRL水平,ELISA检测IL-6水平,RT-q PCR检测泌乳素受体(PRLR)mRNA的表达,Western blot法检测MAPK通路相关蛋白p-p38的蛋白水平。结果:RA患者血清PRL水平明显升高(P0.01),活动期RA患者PRL水平明显高于非活动期RA患者(P0.01)。PRL水平与DAS28评分、ESR和CRP呈正相关(P0.01)。RA患者PBMCs中PRLR水平明显升高(P0.01)。PRL可诱导PBMCs分泌IL-6,siRNA沉默PRLR或采用MAPK通路抑制剂可抑制IL-6的产生。结论:RA患者血清PRL升高与DAS28评分、ESR和CRP呈正相关,PRL可作为预测RA严重程度的指标。PRL通过与PRLR相互作用,激活p38 MAPK通路,从而促进IL-6分泌。     

The correlation between increased serum concentrations of interleukin-6 family cytokines and disease activity in rheumatoid arthritis patients

Purpose

This study was performed to determine whether the serum concentrations of interleukin (IL)-6 family cytokines are elevated in patients with rheumatoid arthritis (RA) and to investigate the relationship between IL-6 family cytokine levels and disease activity in RA patients.

Materials and Methods

We obtained serum samples from 40 patients with RA and 40 age- and sex-matched healthy controls, and we assessed the clinical parameters of disease activity, including the 28-joint disease activity score (DAS28) and C-reactive protein (CRP) levels. Serum samples from five patients with high disease activity (DAS28 > 5.1) were also collected at the eighth week of treatment. Serum concentrations of IL-6, IL-11, and leukemia inhibitory factor (LIF) were measured using an enzyme-linked immunosorbent assay (ELISA).

Results

Serum concentrations of IL-6 family cytokines, including IL-6, IL-11, and LIF, were significantly elevated in patients with RA compared to those of healthy controls. Although there was no significant relationship between IL-6 family cytokine levels and DAS28, the IL-6 levels of patients with RA showed a significant correlation with CRP levels. After eight weeks of medical treatment in patients with high disease activity, a decrease in DAS28 was associated with a significant decrease in the serum concentrations of IL-6 and IL-11.

Conclusion

The serum concentrations of IL-6 family cytokines were significantly elevated in patients with RA, and they decreased with medical treatment. These findings suggest a possible role for IL-6 family cytokines in the pathogenesis of RA.
