[Clinical features of Sjögren syndrome]

Between 1985 and 1995, 134 patients presented to our clinic with complaints of either dry mouth, decreased salivary flow or salivary gland swelling of unknown origin. These patients were diagnosed retrospectively based on the criteria established by the Sjögren's disease research committee (1977), and 30 patients were definitively diagnosed with Sjögren's disease while 23 were considered suspect. The gender distribution of these 30 patients was 25 female (83%) and 5 male (17%). The average patient age was 55.8 years for females and 42.6 years for males. Of 30 patients, 10 (33.3%) had only sicca syndrome and the other 20 (66.7%) had various complications such as collagen diseases, autoimmune diseases, and malignant lymphoid infiltration. Subjects included 14 cases of rheumatoid arthritis (RA), 1 case of systemic lupus erythematosus (SLE), 1 case of RA with periarteritis nodosa (PN), 1 case of progressive systemic sclerosis (PSS) with SLE, 1 case of PSS with Hashimoto disease, 1 case of malignant lymphoma and 1 case of RA with Waldenström's macroglobulinemia. Positive blood tests showed a relatively high incidence of elevated erythrocyte sedimentation ratios (ESR) (75%), elevated IgG levels (69.2%), positive anti-nuclear antibody (52.3%), positive anti SS A antibody (75%) and positive anti-SS B antibody (50%).
