Abstract:
Objective:To analyze the association of CD19+CD24hiCD27+regulatory B cells(Bregs)with ankylosing spondylitis(AS).Methods:Eighty patients with AS in Ganzhou People's Hospital from January 2019 to December 2021 were enrolled as observa-tion group,meantime,another 60 healthy individuals were set as control group.Observation group was further divided into subgroups according to clinical stages and disease activity,advanced stage,ankylosis stage,active stage and non-active stage.Percentage of CD19+CD24hiCD27+Bregs in CD19+cells in peripheral blood of observation group and control group,and observation group patients with different stages were detected and compared,thereafter,relationship between percentage of CD19+CD24hiCD27+Bregs and clini-cal characteristics of AS patients were discussed,such as course of disease,duration of morning stiffness,the Bath Ankylosing Spon-dylitis Disease Activity Index(BASDAI),IL-10,erythrocyte sedimentation rate(ESR),C-reactive protein(CRP)and X-ray classifi-cation of sacroiliitis.Results:Percentage of CD19+CD24hiCD27+Bregs in peripheral blood in observation group was higher than that in control group.Percentage of CD19+CD24hiCD27+Bregs in CD19+cells in AS patients at ankylosis stage was higher than that in patients at advanced stage,and percentage of CD19+CD24hiCD27+Bregs in peripheral blood of patients with bony ankylosis stage was higher than that in patients with fibrous ankylosis stage.Percentage of CD19+CD24hiCD27+Breg in CD19+B cells in active AS patients was sig-nificantly higher than that of patients with stable AS(P<0.05).Serum IL-10 level in observation group was lower than that in control group,while ESR and CRP levels were higher than those in control group,with statistical significance(P<0.05).Percentage of CD19+CD24hiCD27+Breg in CD19+B cells in peripheral blood of AS patients was positively correlated with BASDAI score and serum IL-10 level,while negatively correlated with ESR and CRP levels,and had no correlation with morning stiffness time and X-ray classi-fication of sacroiliitis.Conclusion:Percentage of CD19+CD24hiCD27+Bregs in peripheral blood is reduced in AS patients,moreover,percentage is closely related to disease stage,activity and laboratory indicators IL-10,ESR and CRP,which may be involved in the occurrence and development of AS.
