Background The 1980's ACR classification criteria for systemic sclerosis (SSc) show low sensitivity for diagnosing the disease. A new set of classification criteria by the ACR/EULAR has been developed along 2013.

Objectives To compare the performance of both set of classification criteria. To assess the proportion of SSc and its cutaneous subsets classified with both criteria and to analyse the degree of agreement between them.

Methods Cross-sectional multicentric study with patients from the RESCLE database from the Spanish Group of Systemic Autoimmune Diseases (GEAS) in April 2013. All patients fulfilled LeRoy-Medsger SSc criteria. Epidemiological, clinical, immunological and capillaroscopic variables were collected. 23 pre-selected criteria were first analysed. The ACR/EULAR criteria were compared with the ACR criteria by the proportion of patients fulfilling each criteria and by Cohen's Kappa coefficient. A p<0.05 was considered significative.

Results 1222 SSc patients were included and 1157 were selected for comparing both set of criteria (65 excluded for incomplete data). The most prevalent preselected items were Raynaud's phenomenon (95%), skin thickening (91%), ANA+ antibodies (91%), abnormal nailfold capillaroscopy (89%) and reduced carbon oxide diffusion (78%).

Table 2 shows patients classified as SSc and its Kappa index in their different cutaneous subsets.

Conclusions New ACR/EULAR classification criteria show better accuracy than the old ACR ones. A greater number of patients are classified as SSc, specially in their limited cutaneous, sine and pre-scleroderma subsets.
