ABSTRACT

Objective To investigate the consistency of the lymphocyte immunophenotype between labial gland and peripheral blood of patients with primary Sj(o)gren's syndrome (pSS).Methods Seveny-one pSS patients (referred as pSS group) from rheumatology department and 35 subjects patients with maxillofacial trauma (referred as control group) from department of head and neck surgery of general hospital at tianjin medical university (Tianjin,China) during August 2013 to April 2016 were included into this study.Based on the ratio of CD20 to CD3 in labial gland from pSS patients,they were divided into CD20 high proportion group and CD20 low proportion group.Lymphocyte immunophenotypes in labial glands,course of disease,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) level,immuno-globulin (Ig) and complement levels were compared among groups.Results ① The levels of serum IgG,IgA,IgM and CRP,and ESR were higher,but C4 level was lower in pSS patients than in the control group [IgG:(22 990±8 060) mg/L vs (1 1560±1 290)mg/L,t=l 1.645,P<0.01;IgA:(3 710±1 400) mg/L vs (2 390±800) mg/L,t=6.138,P<0.01;IgM:(1 580±1 300)mg/L vs (920±390) mg/L,t=3.893,P<0.01;ESR:(37±14) mm/1 h vs (14±4) mm/1 h,t=12.723,P<0.01;CRP:(5.9±8.7) mg/L vs (2.5±1.2) mg/L,t=3.199,P<0.01;C4:(180±60) mg/L vs (250±40) mg/L,t=-6.850,P<0.01].② The levels of IgG,IgA,IgM and C3c in labial gland were higher (IgG:Z=-6.264,P<0.01;IgA:Z=-1.997,P<0.05;IgM:Z=-5.459,P<0.01;C3c:Z=-8.533,P<0.01),but Clq was lower in pSS group than in control group (Z=-4.363,P<0.01).③ CD20 was detected in labial gland samples of all pSS patients,in which CD3 was positive in 66 patients,and negative in 5.④ Serum IgG level,ESR were higher in CD20 high proportion group than in low proportion group [IgG:(24 970±7 510) mg/L vs (18 860±7 740) mg/L,t=3.176,P<0.01;ESR:(40±13) mn/1 h vs (32±15) mm/1 h,t=2.148,P<0.05].⑤ The levels of IgG and Clq in labial gland were higher in CD20 high proportion group than in low proportion group [IgG:Z=-5.387,P<0.01;C1q:Z=-4.724,P<0.01].Conclusion pSS patients have a higher proportion of CD20 in infiltrating lymphocytes of the labial gland,accompanied with the changes of immunoglobulins and complements in both labia gland and peripheral blood.

ABSTRACT

ObjectiveThis study explored the change of IL-18,and IFN-γ and their role in the pathogenesis of primary Sj(o)gren's syndrome (pSS) by determining the expression of IL-18,IFN-γ in labial glands and blood of patients with pSS.MethodsThe levels of IL-18,IFN-γ in labial glands of patients with pSS were determined by immunohistochemical method.The level of serum IL-18 was determined with enzyme linked immunosorbent assay ELISA.The level of γ globulin was measured by the cellulose acetate membrane method.SPSS 17.0 statistical software was used for data analysis.The t test,Fisher's exact probability test and index correlation analysis were performed with linear correlation analysis.Spearman's test was used to examine the association between the expression of IL-18 and IFN.ResultsThe positive rate of IL-18 and IFN-γ in patients with pSS was much higher than normal control group(P<0.05).And the IL-18 and IFN-γ levels were positively correlated withpatients with pSS (P<0.05).The level of serum IL-18 in patients with pSS was (216±85) pg/ml,which was much higher than normal control group(39±8) pg/ml.The IL-18 level and γ globulin(23.2±2.6)% was positively correlated in patients with pSS (r=0.538,P<0.05).ConclusionThe expression of IL-18 and IFN-γ in labial glands of patients with pSS are much higher in patients with pSS than those of the normal controls.Theresults have shown that IL-18 and IFN-γ may be involved inthe pathogenesis of pSS.
