SAT0206 MINOR SALIVARY GLAND BIOPSY AND SEROLOGICAL PROFILE IN PRIMARY SJÖGREN’S SYNDROME: A SINGLE TERTIARY REFERRAL CENTER EXPERIENCE
2020
Background: In the diagnosis of primary Sjogren’ syndrome (SS), salivary gland ultrasound is useful tool. Until now, there is no data for ultasonographic changes of major salivary glands over time. Objectives: This study aimed to evaluate the changes in abnormalities of salivary gland ultrasound (SGUS) over time in patients with pSS. Methods: Patients with pSS (n=70) and idiopathic sicca syndrome (n=18) underwent SGUS twice at baseline and 2 years later. The semi-quantitative SGUS score (0-48) was used, which comprises five parameters: parenchymal echogenicity, homogeneity, hypoechoic areas, hyperechogenic reflections, and clearness of posterior borders. The intraglandular power Doppler signal (PDS) was also assessed. The changes of these SGUS variables were compared in patients with pSS and idiopathic sicca syndrome. Results: The median (interquartile range) total SGUS scores at baseline was 27 (14) in patients with and 4 (3) in those with idiopathic sicca syndrome (p Conclusion: The structural abnormalities in major salivary glands assessed using SGUS scores progressed significantly in patients with pSS. In pSS group, 18.6% patients had worsening SGUS scores during 2 years. Intra-glandular hypervascularity was associated with worsening of salivary gland abnormalities.
