No associations were observed between CCL2 protein levels and EULAR Sjogren’s Syndrome Patient Reported Index (ESSPRI) (clinical index designed to measure the severity of pSS symptoms), presence of sicca complex items (fatigue, chronic pain or dryness [46]), focus score, autoimmunity markers (ANA, anti-Ro/SSA positivity), and objective exocrine testing (Schirmer test, salivary gland scintigraphy, or salivary flows). Here, CCL2 is linked to Autoimmunity.
