About this study
Official title: Prospective Multicenter Study of Ultrasound Evaluation of Salivary Glands in Patients with Sjögren's Disease Compared with Patients with Connective Tissue Diseases (lupus, Scleroderma, Rheumatoid Arthritis) and Healthy Subjects with Dry Syndromes
Prospective multicenter cross-sectional study evaluating ultrasound of the main salivary glands (2 parotid and 2 submandibular) in patients with Sjögren's disease compared with patients with other connective diseases (rheumatoid arthritis (RA), lupus, scleroderma) and control patients (patient with dry syndrome without the above-mentioned autoimmune disease).
Read the detailed description
This is a non-interventional study involving patients who are routinely monitored for their disease, and who typically benefit from ultrasound of the parotid and submandibular salivary glands as part of their dry mouth syndrome. Recruitment will be facilitated by the fact that these will be "general population" patients with Sjögren's disease, lupus, RA, scleroderma with dry syndrome, and control patient.
The study will be conducted over a single visit, including a clinical examination and an ultrasound scan. Ultrasound will not be blinded to the clinic, so we will need only one examiner per center.
This is a study in routine care, with no additional costs and no expected constraints. The examination will be carried out as part of their routine follow-up.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Sjogren syndrome | Ultrasound of the parotid and submandibular salivary glands in routine care of patients with Sjögren | |
| Other autoimmune diseases (Lupus/RA/Scleroderma) | Ultrasound of the parotid and submandibular salivary glands in routine care of patients with other autoimmune diseases (Lupus/RA/Scleroderma) | |
| Dry syndrome | Ultrasound of the parotid and submandibular salivary glands in routine care of patients with dry syndrome |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluate the rate of patients with structural anomalies of the salivary glands, for each of three populations
The salivary gland assessment score will be evaluated according to the OMERACT score (0-3) for each group of patients.
Measured: Baseline
Secondary outcomes (2)
Evaluate the proportion of patients with ultrasound abnormalities in each subgroup.
Evaluate the proportion of patients with B-mode ultrasound abnormalities (0-3) in each subgroup.
Measured: Baseline
Evaluate the proportion of patients with vascular anomalies in each subgroup
Study of the contribution of Doppler ultrasound to the study of salivary gland vascularization in each subgroup
Measured: Baseline
