Abstract：
OBJECTIVE:To investigate consistency of lymphocyte immunophenotype between labial gland and peripheral blood in patients with primary Sjogren's syndrome (pSS). METHODS:Seventy-one pSS patients and 35 patients with maxillofacial trauma were included in the study. Based on the ratio of CD20 to CD3 in labial gland from 71 pSS patients, they were divided into the high and (n = 48) and low CD20 expression group (n = 23). Lymphocyte immunophenotypes in labial glands, course of disease, erythrocyte sedimentation rate (ESR), C-reactive protein, immunoglobulin, and complement levels were analyzed. RESULTS:In the labial gland, the levels of IgG, IgA, IgM, and C3c were higher, but C1q was lower in the pSS group than in the control group (all P < .05). CD20 was detected in labial gland samples of all pSS patients, in which CD3 was positive in 66 (93.0%) patients, and negative in 5 (7.0%). The plasma levels of IgG, IgA, IgM, and CRP, and ESR were higher, but serum C4 level was lower in pSS patients than in the control group (all P < .01). Serum IgG level, ESR, and labial gland CD20 were higher in the high CD20 expression group than the low expression group (all P < .05). CONCLUSION:Primary Sjogren's syndrome patients had a higher expression of CD20 positive infiltrating lymphocytes of the labial gland, accompanied with the changes of immunoglobulins, and complements in both the labial gland and peripheral blood.
