Ultrasound Characteristics of the Salivary Glands in Patients With Rheumatoid Arthritis
The prevalence of Sjogren's syndrome (SS) in rheumatoid arthritis (RA) patients varies from 3.5 to 31%. Between 30% and 90% of patients with (RA) have dry eye and/or mouth syndrome. To date, no studies have assessed whether RA patients have echostructural changes in their salivary glands suggestive of SS and the factors associated with these changes.The aim of this study is to investigate if there are changes in the echostructure of the salivary glands of RA patients, especially in patients with dry syndrome.
⁃ Patient, male or female, over 18 years of age, followed in the Rheumatology Department of the Clermont-Ferrand University Hospital, capable of giving informed consent to participate in the research.
