Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: A new consensual scoring system for Ultrasonography (US) of the salivary gland in pSS is required and endorsed by an international group of experts (US-pSS Study group).
The objectives were to define and validate relevant ultrasonographic components of the salivary glands in Sjogren.
Methods: A consensus exercise about definitions of the different ultrasonographic components of the salivary glands was done and discussed between experts on the field of US pSS during 2 annual meetings. Using these preliminary definitions, a reliability exercice was done on static images (60 images of both parotid and submandibular glands were read twice). Then an interreliability exercise was performed by a group of 5 experts with acquisition on 20 pSS patients. On this basis, we selected the most relevant US components, to build the new US-pSS score
Results: Eight different components evaluating the abnormal parenchyma of salivary glands were defined (echogenicity, homogenicity, presence or absence of hyperechoic bands, number of hypoechoic ares, and location of hypoechoic areas, lymph nodes, presence or absence of calcifications, visualisation of posterior border) in Sjögren. Concerning reliabilities, the web exercise demonstrated good inter and intra observers agreements applying these definitions on US parotid gland and submandibular glands (table 1) particularly in taking homogeneity as the principal important item in this definition. In contrast posterior border or presence of calcification had low agreement. The inter reliability exercice on pSS patients showed good kappa values concerning parotids glands but very low for submandibular glands
Conclusion: This is the first consensus-based US definitions on salivary glands and its elementary components. These results of the reliability exercice on static images showed good results and permit to apply these preliminary definitions on pSS patients with good results in parotids glands. With these results, a new US score could be assessed and used in routine practice
