The aim of this study was to characterize the subsets of circulating CD56\n                    <jats:sup>+<\/jats:sup>\n                    NK cells in pSS patients and their potential value in the diagnosis and\/or prediction of prognosis in patients with pSS.\n                    <jats:italic>Methods<\/jats:italic>\n                    . We included 52 pSS patients fulfilling the 2002 AECG criteria or 2012 ACR criteria and 20 age\u2010 and gender\u2010matched healthy volunteers. The frequency and absolute number of NK cells and CD56 NK cell subsets in peripheral blood samples were detected by flow cytometry. Other laboratory parameters such as the IgG level and complement protein levels were extracted from the clinical system.\n                    <jats:italic>Results<\/jats:italic>\n                    . Both the frequency and the absolute number of peripheral blood NK cells were reduced in pSS patients compared to healthy controls. The proportion of CD56\n                    <jats:sup>bright<\/jats:sup>\n                    NK cell subset was increased, and the proportion of CD56\n                    <jats:sup>dim<\/jats:sup>\n                    NK cell subset was decreased among NK cells, resulting in the ratio of CD56\n                    <jats:sup>bright<\/jats:sup>\n                    NK to CD56\n                    <jats:sup>dim<\/jats:sup>\n                    NK which was significantly elevated in pSS patients. ROC analysis indicated that the AUC of CD56\n                    <jats:sup>bright<\/jats:sup>\n                    NK\/CD56\n                    <jats:sup>dim<\/jats:sup>\n                    NK ratio was 0.838, and the best diagnostic cut\u2010off point was 0.0487 for pSS patients. Furthermore, this CD56\n                    <jats:sup>bright<\/jats:sup>\n                    NK\/CD56\n                    <jats:sup>dim<\/jats:sup>\n                    NK ratio was positively correlated with the IgG level and negatively correlated with the complement protein C3 and C4 levels. More importantly, the CD56\n                    <jats:sup>bright<\/jats:sup>\n                    \/CD56\n                    <jats:sup>dim<\/jats:sup>\n                    NK ratio was either slightly increased or not changed in other autoimmune diseases such as SLE and IgG4\u2010related disease.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    . Our findings suggest that the ratio of blood CD56\n                    <jats:sup>bright<\/jats:sup>\n                    NK to CD56\n                    <jats:sup>dim<\/jats:sup>\n
