Abstract:
Aim To study cytokine(CK) changes of IL-6,IL-8,sIL-2R and TNF-a levels in sera from patients with juvenile rheumatoid arthritis(JRA) and rheumatoid arthritis(RA) and its correlation with the conventional inflammation indexes,erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP). Methods Levels of IL-6,IL-8,sIL-2R and TNF-a in serum from 30 JRA patients and 34 RA patients,in the synovial fluid (SF)from 4 JRA patients,7 RA patients,6 osteoarthritis(OA) patients and 9 meniscitis(MT) patients were detected by sandwich ELISA. Results As compared with control group,① levels of IL-6 and SIL-2R in sera from 30 JRA patients and 34 RA patients and levels of IL-8 in sera from 30 JRA patients possessed marked difference P∨ 0.01 and P∨ 0.05,respectively.② There were significant difference among serum IL-8 and sIL-2R levels from systemic JRA patients, pauciaticular JRA patients,and serum IL-6 levels from polyarticular JRA patients(P<0.01). ③ There were remarkable difference among SF sIL-2R levels from 4 JRA patients and 7 RA patients and in SF IL-6 levels from 7 with RA patients.④ There were obvious correlativity between serum IL-6,sIL-2R levels and changes of serum ESR and CRP from the JRA patients(r=0.532 and r=0.621,respectively). Conclusion ① IL-6 and sIL-2R exhibit a close correlativity with the activity of JRA and RA,which is the main index of activity of JRA and RA diseases.② sIL-2R might not only participate in systemic pathologic process in JRA and RA diseases,but also serves as a major CK in local articular injuries.IL-6 participates in local articular injuries too,and seems to play a more important role in local articular injuries of RA.③ IL-8 may participate in systemic pathologic process of JRA,but play a minor part in local articular injuries.
