ABSTRACT
Objective The purpose of the study was to investigate the changes and clinical significance of matrix metalloproteinase (MMP)-1,MMP-3,tissue inhibitor of metalloproteinase (TIMP),interleukin (IL)-1,tumor necrosis factor (TNF)-α and transforming growth factor(TGF)-β in juvenile idiopathic arthritis (JIA).Methods Thirty-two JIA subjects and 28 controls (traumatic arthritis patients) were included into this study.The MMP-1,MMP-3,TIMP,IL-1,TNF-α and TGF-β level in the serum and synovia were assessed by ELISA.The WBC count,the level of CRP,ESR,RF were also detected.Independent t-test and Pearson's analysis were adopted for data analysis.Results ① The level of MMP-1,MMP-3,IL-1 and TNF-α in the serum was (158±67) ng/ml,(212±89) ng/ml,(39±19) pg/ml,(26±10) pg/ml respectively,which was significantly higher than that of the control group (all P<0.05) ; the ratio of MMP-3/TIMP-1 (0.86±0.32) was higher in the study group than that of the control group (P<0.05),while the value of TIMP-1,TGF-β was (248±88),(17±9) ng/ml respectively,which was lower than that of the control group (P<0.05).The value of seral MMP-3,MMP-3/TIMP-1 was positively correlated with that of WBC,CRP,ESR in the JIA group (all P<0.05).② The value of MMP-1,MMP-3,IL-1 and TNF-α in the synovia was (216±78) ng/nl,(766±291)ng/ml,(56±21) pg/ml,(36±14) pg/ml respectively,which was higher than that of the control group (all P<0.05); the ratio of MMP-3/TlMP-1 (2.68±0.89) was higher than that of the control group (P<0.05),while the value of TIMP-1,TGF-β was (286±88) ng/ml,(12±4) ng/ml respectively,which was lower than that of the control group (all P<0.05).③ The value of MMP-1,MMP-3,TIMP-1,IL-1 and TNF-α in the synovia was higher than that in the serum (all P<0.05),while the value of TGF-β was lower than that in the serum (P<0.05).Conclusion The value of MMP-1,MMP-3,IL-1 and TNF-α increases both in the serum and synovia,while the value of TIMP-1 decreases.The value of TGF-β decreases,which may have protective effect on JIA.The ratio of MMP-3/TIMP-1 in the serum is positively correlated to inflammation parameters,which may be used to judge the activity of illness in JIA.
