Title: Sjögren's Syndrome Poster I: Clinical Insights into Sjögren's Syndrome
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose:
To analyse the epidemiological, clinical and immunological characteristics at diagnosis of the largest international cohort of patients diagnosed with primary Sjögren syndrome (SS) according to the 2002 AE classification criteria.
Methods:
The Big Data Sjögren Project is an international, multicentre registry formed in 2014 to take a “high-definition” picture of the main features of primary SS at diagnosis by merging international SS databases. International experts participating in the EULAR-SS Task Force were invited to participate. By June 2015, the database included 6120 consecutive patients recruited from 14 countries (Europe, America and Japan), of whom 6047 fulfilled the 2002 classification criteria for primary SS (some diagnostic tests are pending in the remaining patients). The main features at diagnosis (time of criteria fulfilment) or at recruitment were collected and analysed.
Results:
Of the 6047 patients, 5648 (93.4%) were women and 399 (6.6%) were men (female:male ratio, 14:1), with a mean age at diagnosis of primary SS of 49.96 years (range, 5-97), of which 79% were Caucasian and 81% from European countries. The frequency of fulfilment of the 2002 criteria was: 94.1% for dry eye, 93.6% for dry mouth, 88.3% for positive salivary gland biopsy, 86% for positive ocular tests, 79.1% for positive oral tests and 72.2% for positive Ro/La autoantibodies. With respect to the criteria fulfilled, 10.6% fulfilled 3 criteria, 30.6% 4 criteria, 40.7% 5 criteria and 18% all 6 criteria. The percentage of diagnostic tests performed varied from 70% to nearly 100%: Ro/La autoantibodies were tested in 99.5% of patients, ocular diagnostic tests (Schirmer’s test and/or corneal stainings) in 89.7%, oral tests in 81.3% and salivary gland biopsy in 71.8% of patients. The four diagnostic tests included in the 2002 AE criteria were made (complete diagnostic approach) in 3459 (57%) patients, while in the remaining 2588 (43%), only two or three tests were made (incomplete diagnostic approach). A complete diagnostic approach was more frequent in patients from non-European countries (73% vs 55%, p<0.001), Ro/La negative patients (79% vs 50%, p<0.001), ANA-negative patients (75% vs 57%, p<0.001), RF-negative patients (66% vs 55%, p<0.001) and patients with normal C3/C4 values (74% vs 59%, p<0.001).
Conclusion:
In the largest cohort of primary SS patients diagnosed homogeneously according to the 2002 AE criteria, a full diagnostic evaluation was made in less than 60% of patients. In addition, the diagnostic approach was heterogeneous and varied according to the geographical area and the baseline immunological profile; in contrast, gender and age did not influence the number of diagnostic tests made to achieve fulfilment of the criteria.
