Session Title: Systemic Sclerosis & Related Disorders – Clinical Poster II
Session Type: Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: Different criteria aiding the diagnosis of Raynaud’s phenomenon (RP) have been proposed. Wigley’s “RP criteria 2002”, defined RP by history of cold sensitivity, accompanied by pallor and/or cyanosis, and a 3-item questionnaire1. International Consensus Criteria proposed criteria (“RP criteria 2014”) take a three-step conditional approach (i.e. a screening question, assessment of colour changes and a disease score calculation2. As the latter criteria seem more stringent for RP, we aimed to compare the agreement between the two criteria sets and their correlation with nailfold capillaroscopy (NFC) findings and results of immunoserological tests.
Methods: This cross-sectional study was performed between January 2018 and December 2019 at our secondary/tertiary rheumatology centre. Both RP criteria questionnaires were applied by the rheumatologist to all patients and the same day the NFC was done. The agreement between the criteria was determined by the Cohen κ-test. The correlation between the two criteria sets, NFC and immunoserological tests (antinuclear antibodies and scleroderma specific antibodies) was calculated with the Pearson correlation test.
Results: We included 565 consecutive patients referred for NFC (84.1% female, median age (IQR) 51.1 (40.1–61.6) years). “RP criteria 2002” and “RP criteria 2014” were fulfilled in 485/565 (85.8%) and 248/565 (43.9%) patients, respectively. The κ-coefficient of agreement between the criteria was 0.22 (95% CI 0.11-0.26). Table 1 shows the correlations between RP criteria and results of NFC and immunoserology.
Conclusion: We found a low level of agreement between the two criteria sets. “RP criteria 2014” correlated better than “RP criteria 2002” with scleroderma specific immunoserology and the scleroderma pattern at NFC, albeit the correlation was low for both criteria.
