Role of Ultrasound in Diagnosis of Sjogren’s syndrome
Ultrasound in Diagnosis of Sjogren’s syndrome
Background: Primary Sjögren’s syndrome is a multisystem autoimmune disease characterized by hypofunction of salivary and lacrimal glands and possible multi-organ system manifestations. Over the past 15 years, three sets of diagnostic criteria have been proposed, but none has included salivary gland ultrasonography. However, recent studies support its role in the diagnosis and prognostic evaluation of patients with Sjögren’s syndrome. Aim:The aim of the present study was to determine the role of ultrasound in diagnosis of Sjögren’s syndrome and to assign scoring based on texture morphology of parotid gland seen on ultrasound in patients.Subjects and Methods: In this study,30 patients of age between 20-60 years with Sjögren’s syndrome referred for ultrasonography of neck to the department of radiodiagnosis, PDU Medical college and Civil hospital, Rajkot, Gujarat, over a period of 1.5 years from 01/05/2018 to 01/11/2019 are included. Results: SGUS was performed by the same investigator, an experienced radiologist, using a real-time scanner (LogiqP9; GE Healthcare) with a 12-MHz linear array transducer. Both the parotid and submandibular glands were scanned and echostructure of each gland was graded on a scale of 1 to 4.Conclusion: Our study contributes to the conclusion that ultrasonography can be used as a primary modality of imaging to early diagnose Sjögren syndrome in a non- invasive way.
