Sjögren's syndrome (SS) is an autoimmune disease that occurs predominantly in middle-aged and older women. Although focus score (FS) and lesion grade are determined at pathological diagnosis, few reports have examined whether these results reflect clinical symptoms. In this study, we examined and compared the results of comprehensive immunohistochemical staining of lymphocytes and NF-κB pathway in labial gland biopsies, clinical test data, and radionuclide imaging findings. One hundred labial gland biopsy specimens obtained from 20 female patients with primary SS (5 specimens per patient) were studied. Hematoxylin-eosin-stained specimens were reviewed and FS were calculated. Immunohistochemical staining of CD4, CD8, CD20, CD25, Foxp3, NF-κB, TNFAIP3 and IκBα was performed, and the results were compared with anti-SS-A/Ro (SS-A), anti-SS-B/La (SS-B) and antinuclear antibodies (ANA), and salivary gland scintigraphy findings. FS were significantly higher in the SS-A-, SS-B- and ANA-positive groups than in the respective -negative groups (p < 0.05). Of eight SS-A-positive and SS-B-negative cases, mean FS was 1.9 (seven cases: FS ≥ 1.0) and six cases were ANA-positive. In four SS-A-positive and SS-B-positive cases, mean FS was 3.2 (all cases: FS ≥ 1.0) and all cases were ANA-positive. In immunohistochemical staining, CD4-positive T cells tended to be more abundant than CD8-positive T cells. Small numbers of Foxp3-positive cells were found in all cases. NF-κB, TNFAIP3 and IκBα were positive in the acini, ductal epithelium, and lymphocytes in all cases. The above findings indicated a relationship between FS and clinical test data, and the association of NF-κB pathway with the pathophysiology of primary SS.
