Popis: Objective Patients with systemic lupus erythematosus (SLE) display symptoms that are not always related to disease activity and may distort clinical trial results. Recently, a clinical categorization based on the presence of type 1 (inflammatory manifestations) and/or type 2 (widespread pain, fatigue, depression) symptoms has been proposed in SLE. Our aim was to develop a type 2 score derived from the Short-Form health survey (SF-36) to categorize SLE patients and to compare immunological and transcriptomic profiles between groups. Methods Seventeen items from the SF-36 were selected to build a type 2 score for 50 SLE patients (100 visits; LUPUCE cohort) and the SLEDAI was used to define type 1 symptoms. Patients were categorized in four groups: minimal (no symptoms), type 1, type 2 and mixed (both type 1 and type 2 symptoms). Clinical, immunological and transcriptomic profiles were compared between the groups. Results Type 2 scores ranged from 0 to 31, with a cut-off value of 14 (75th percentile). The sample categorization was: minimal in 39%, type 1 in 37%, type 2 in 9% and mixed in 15%. Type 2 patients were older than minimal patients and had a longer disease duration than type 1 and mixed patients. Immunological data and modular interferon signatures did not differ between the groups. Conclusion Patients with SLE can be categorized into four clinical groups using the SLEDAI score and our SF-36-derived type 2 score. This categorization is non-redundant with immunological or transcriptomic profiles and could prove useful to stratify patients in clinical trials.
