The lack of consensus between each of these SGUS scoring systems also had a negative impact on the reproducibility of the examination so far. By offering an updated consensual classification, the OMERACT initiative therefore constitutes an undeniable progress for the diagnosis of pSS.
Recently, in a multicentre prospective study of 97 patients referred for clinical sicca syndrome (39 pSS and 22 secondary Sjogren’s syndrome (sSS) according to American-European Consensus Group (AECG) criteria in comparison with 36 controls), we …
