Abstract:
Objective To explore the changes of inflammatory factors in patients with different stage of rheumatoid arthritis (RA) ,and to study the changes of immune microenvironment in patients with RA .Methods The serum levels of tumor necrosis factor(TNF) ,interleukin‐10(IL‐10) ,interleukin‐6(IL‐6) ,interleukin‐1β(IL‐1β) and interleukin‐4(IL‐4) in patients with RA on ac‐tive stage(36 cases) ,patients with RA on remitting stage and healthy individuals (30 cases)were detected by using cytometric bead array .Results The serum levels of IL‐6 ,IL‐1βand TNF in active stage RA group were higher than those in control group and re‐mitting stage RA group ,while serum levels of IL‐4 and IL‐10 were lower than those in control group and remitting stage RA group , and the differences were statistically significant (P<0 .05) .The serum levels of IL‐6 and IL‐1βin remitting stage RA group were significantly higher than those in control group(P<0 .05) .There were no significant differences in levels of IL‐4 ,IL‐10 and TNF between remitting stage RA group and control group(P>0 .05) .As the disease develops ,except for IL‐6 which tended to be stable , the serum levels of IL‐4 and IL‐10 had a rising trend ,while serum levels of IL‐1βand TNF had a downward trend with the progres‐sion of RA .Conclusion There is an imbalance between Th1 and Th2 cytokines in patients with RA on active stage ,in which Th1 cytokines are dominantly expressed .Periodic detection of inflammatory factors according to the course of RA could provide a relia‐ble basis for the assessment of disease activity .
