Clinical Trial Summary

A prospective study will be conducted to evaluate inflammatory activity in lacrimal glands due to Sjögren's syndrome on Superb Microvascular Imaging (SMI), gray scale ultrasound (US), color Doppler US and Power Doppler US.


Clinical Trial Description

In the disease activity index recommended by EULAR, the European Rheumatology Association, to evaluate the disease activity of patients with Sjögren's syndrome, it is recommended to measure the swelling in the gland by performing a clinical examination for glandular activity. However, it is not practical to measure the size of these glands due to their location. In studies in which lacrimal glands were evaluated by ultrasonographic methods, parameters such as gland size measurement, gland heterogeneity and Doppler activity were reported to be very successful in differentiating patients from healthy controls. Determining the presence and characteristics of vascular flow is an important part of ultrasonographic examinations. However, small vessels and low velocities are not always possible to detect with conventional color and power Doppler ultrasound. Sonographic examination will be inconclusive, especially if the presence of vascular flow or activity needs to be addressed as a basis for diagnosis and follow-up. Superb Microvascular Imaging (SMI) is a new vascular imaging mode that provides low speed and visualization of microvascular flow. SMI uses an algorithm that can suppress parasitic reverberations to extract flow signals and displays this information as a color overlay image or a monochromatic or color flow map.There are studies that report that Superb Microvascular Imaging (SMI), a new and up-to-date Ultrasonography technology, is more sensitive in detecting the activity of Rheumatic diseases. In this respect, there are no studies evaluating the inflammatory activity of lacrimal glands with SMI method. Therefore, a prospective study will be conducted to evaluate the inflammation detecting performance of SMI, gray scale US, color Doppler US and Power Doppler US. The null hypothesis that there is no difference between Doppler US and SMI methods in the detection of increased inflammatory activity in Sjögren's syndrome patients. ;
