Abstract:
Objective To clarify the diagnostic value of salivary gland ultrasonography in Sj(o)gren's syndrome (SS),and its correlation with the disease activity index and important organs involvement were analyzed.Methods A total of 116 patients with SS were involved,including 71 cases of primary SS and 45cases of secondary SS.Ultrasonography examination of major salivary glands was conducted for these patients,at the same time the clinical data including inflammatory parameters,the immunological parameter and the involved systems were collected.Ultrasonography examination was conducted in 49 cases as the control group.Use t test,x2test and analysis of variance for statistical analysis.Results The positive rate of salivary gland uhrasonography in SS (56/116,48.3％) was significantly higher than that of the normal control groups (1/49,2.0％),(The chi-square value was 32.57,P＜0.05),the sensitivity of salivary gland ultrasonography in primary SS (62.0％) was obviously higher than secondary SS (27％),(The Chi-square value was 13.75,P＜0.01).The specificity of salivary gland ultrasonography was 98％.The scores of salivary gland ultrasonography had shown positive correlation with the erythrocyte sedimentation rate,the levels of Immunoglobulin (Ig)G,and RF(r=0.234,0.353,0.176;P=0.002,0.000,0.013),and negative correlation with the white blood cell count (r=-0.292,P=0.000).Conclusion Salivary gland ultra-sonography provides additional evidence for the diagnosis of SS,particularly in primary SS groups.The scores of ultrasonography are correlated with inflammatory biomarkers,indicating that salivary gland ultrasonography is related to disease activity.
