Abstract

Abstract : Background: Although the prognosis for systemic lupus erythematosus (SLE) has greatly improved, many patients experience the disease flare-up. Little is known about the disease flare-up patterns and predictors in a long-term follow up. Objectives: The aim of this study was to clarify the outcomes and predictors for disease flare-up in a monocentric cohort of Japanese patients with SLE. Methods: Among 2390 SLE patients registered in our JUDE (Juntendo University Database of Erythematosus) study, diagnosed between 1964 and 2004, 423 for whom long-term follow-up was possible between 1973 and 2012 were investigated. Disease activity patterns were defined using the SLE Disease Activity Index-2000 (SLEDAI-2K) 1 .Disease flare-up was defined according to the SELENA-SLEDAI flare composite 2 . SLE patients were included if they fulfilled the ARA 3 or ACR 4 criteria for SLE. Data on disease activity, severe flare-up and treatment were collected, and the initial clinical manifestations of disease flare-up were analyzed. The censoring period for analysis was May to October 2013. Results: The mean follow-up duration was 25.9 years. During follow-up, 118 (27.9%) of the 423 patients experienced at least once flare-up after initial treatment with corticosteroid or corticosteroid plus immunosuppressant. More than half (58.5%) of the patients who suffered flare-up were accumulated within 5 years, irrespective of the initial therapy. Comparison of the age at onset among patients who suffered flare-up more than twice in 10 years after the initial therapy showed that teenage onset accounted for a greater proportion than patients who developed SLE in their thirties and beyond. The most common manifestation associated with flare-up was thrombocytopenia. Cluster analysis showed that renal disturbance was distinct from arthritis among manifestations of both onset and flare-up. Conclusions: This long-term monocentric cohort follow-up study of 423 Japanese SLE patients revealed that 27.9% suffered flare-up after the initial therapy, irrespective of the initial treatment regimen.
