Abstract

The study aimed at assessing the epidemiology and clinical features of systemic lupus erythematosus (SLE) in Reunion Island, South West of Indian Ocean. A retrospective study was conducted at the University Hospital of La Reunion (Saint-Denis) by charts review from 2004 to 2015. Patients with a SLE diagnosed over 15 years according to SLICC 2012 criteria were included. Incidence and prevalence were inferred from national health insurance database and population census results. In total, 123 patients met inclusion criteria: 116 were women (94%) and mean age at diagnosis was 34.7±13.4 years. Ten percent of all patients had a least one parent with autoimmune disease, and 4% with lupus. The main manifestations were musculoskeletal (89%) and mucocutaneous with acute or subacute lesions (76%), alopecia (25%), ulcers (15%) and discoid lupus (11%). Lupus nephropathy occurred in 39%, serositis in 31% and neurological features in 15%. Antinuclear antibodies were positive in 99% (threshold >1/80), and associated to anti-DNA (70%), anti-SSA (47%), anti-RNP (42%), and anti-Sm (37%). APL syndrome was diagnosed in 15%. The average annual standardized incidence between 2010 and 2016 was 6.3 cases per 100,000 inhabitants (95% confidence interval [CI]: 5.6-6.9). The prevalence was 76 cases per 100,000 inhabitants in 2016 (95% CI: 70-82). Lupus in the multi-ethnic population of Reunion Island is characterized by high incidence and high rates of articular and renal manifestations, as well as anti-ENA antibodies.
