SJÖGREN SENDROMUNDA ULTRASON ELASTOGRAFİ BULGULARI

Abstract

Background/Aims: In Sjögren’s syndrome the basic histopathology in all affected organs is progressive lymphocyte infiltration This causes a change in tissue elasticity in the major salivary glands. The purpose of this study is to investigate salivary gland stiffness in primary Sjögren’s syndrome via shear wave elastography.
 Material and Methods: According to the 2016 American European Consensus Group criteria, 47 female cases were included in the study as the "patient group" by two rheumatologists. A total of 41 healthy female volunteers, who were in a similar age group and had no symptoms of dry mouth or sicca, and no diagnosis of salivary gland disease, constituted the "control group" of the study .The paired parotid and submandibular glands of all subjects were examined with shear wave elastography. The study was conducted between October 2018-October 2019
 Results: In our study, there was a significant difference in both parotid glands' tissue elasticity values in both speed and kPA values in cases with pSS compared to the control group. However, when the submandibular glands were evaluated, no significant difference was found between the two groups. In our study, no relationship was found between the duration of symptoms and elasticity values.
 Conclusions :The fact that shear wave velocity (m / sec) and elasticity value (kPA) values are higher in the evaluation of the parotid gland by SWE technique in patients with pSS than the control group makes SWE an easy, non-invasive, and effective imaging method in Sjögren's Syndrome.
