Abstract:
Objective To investigate the change of Th22 cells in peripheral blood of patients with Primary sjogren’s syndrome (pSS)and evaluate clinical significance.Methods 37 patients with pSS from January 2014 to November 2015 were enrolled the study as the observation group.Then 37 healthy adults receiving check-up during the same period were selected as con-trol groups in accordance with the proportion of 1∶1.Flow cytometry was performed to evaluate the levels of Th22 cells in peripheral blood,and tenzyme-linked immuno sorbent assay (ELISA)was used to measure the serum IL-22 levels.Pearson analysis was performed to investigate the relationship between Th22 level and serum IL-22 level,C3,C4,anti-SSA,anti-SSB, ANA antibody,EULAR Sjogren's syndrome disease activity index (ESSDAI)score in observation group.Then the levels of Th22 cells and serum IL-22 were compared among different labial gland pathologic stage in patients with pSS.Results The levels of Th22 cells and serum IL-22 in the observation group were (2.53±1.56)%,718.6±176.8 pg/ml respectively,and significantly higher than (1.24±0.51)%,258.9±72.4 pg/ml in control group (P<0.05).Th22 cell level was positively related with the level of serum IL-22,anti-SSA,anti-SSB and ESSDAI score,and negatively related with the content of C3 and C4 (P<0.05).There were no significant differences in the levels of Th22 cells and serum IL-22 different labial gland pathologic stage in patients with pSS (P>0.05).Conclusion The levels of Th22 cells and serum IL-22 significantly in-creased in patients with pSS,and related to other inflammatory indexes and disease activity,so they may participate in the genesis and development of pSS.
