PReS-FINAL-2356: A comparison of the American college of rheumatology and the systemic lupus international collaborating clinics classification criteria for systemic lupus erythematosus using data from the uk juvenile systemic lupus erythematosus cohort study

Significant differences in disease onset and course have been described in adults and children with SLE. Making a diagnosis of JSLE is complex. The United Kingdom JSLE Cohort Study[1] collects demographic and prospective clinical data on patients fulfilling the ACR classification criteria for SLE ≤18 years of age and those with probable evolving disease from time of diagnosis onwards. In 2012 the SLICC group proposed a new classification designed to enhance and improve the diagnosis of SLE. The aim of our study is to determine if the SLICC classification facilitates earlier diagnosis of SLE in a large juvenile cohort.
