Participants with Primary Sjogren's Syndrome

Healthy controls

Sarcopenia Assessment

Muscle mass will be calculated via bioimpedance analysis method. Fat Free Mass will be recorded using TANITA BC 532 Bioimpedance Device and Skeletal Muscle Mass and Skeletal Muscle Mass will be calculated.

Grip strength will be evaluated with JAMAR dynamometer. The patient is positioned in a chair with the elbow flexed to 90 degrees and the wrist in a neutral position, and he/she is asked to grip as strong as he/she can do for 3 seconds. The test is repeated 3 times and the highest value is recorded.

The patient will be asked to walk 4-meters for two times. The shortest time to walk through this distance will be recorded.

This test includes the calculation of the time it takes to sit and get up from the chair 5 times while the arms are crossed over the shoulders.

ESSDAI was developed to determine the disease activity level specifically for Sjogren's Syndrome. It includes 12 domains (ie, organ systems: cutaneous, respiratory, renal, articular, muscular, peripheral nervous system (PNS), central nervous system (CNS), haematological, glandular, constitutional, lymphadenopathic, biological). Each domain is divided into 3-4 levels of activity. A score less than 5 indicates a low level of disease, a score between 5 and 13 indicates a moderate level, and a score of more than 14 indicates a high level of active 14. It is a scoring system that evaluates every domain between 0 and 3.
