In clinical practice it is up to the clinician to use their judgement in making a diagnosis of pSS. In research it is essential to have agreed classification criteria so that there is confidence that participants in a study have the specified condition. During the 1980's a number of classification criteria were proposed with a major debate as to the advantages and disadvantages of each of these criteria.
In 1988 a working group of 29 experts from 12 European countries initiated a study to develop consensus criteria. They published their initial findings in 1993 and in 2002 Vitali et al published the American European Consensus Group Criteria (AECG). The AECG criteria have been the most widely used “gold-standard” criteria for the classification of pSS in research studies. Criteria are never fixed in perpetuity, however, and as new technology such as ultrasound becomes more widely used or new data becomes available further revision is likely. In 2013, an International Collaboration, the Sjögren's International Clinical Collaborative Alliance (SICCA) funded by the National Institutes for Health in the USA collected data from 1618 participants to devise the American College of Rheumatology (ACR) preliminary criteria for SS and in 2016 following a further international consensus group exercise the American College of Rheumatology – European League against Rheumatism (EULAR) consensus criteria for Sjögren's syndrome have been published.
In this presentation I will go through the development of these criteria, the underlying rationale and by the end of the talk attendees should have a better understanding of how these criteria can be used in research and to support clinical practice.
