The aim of this study is to describe the clinical and immunological profile of this disease. Materials and methods: Descriptive study of 5 patients with rhupus and follow-up by an internal medicine department over a period from 2005 to 2020. Diagnosis selected according to the ACR criteria of PR and SLIIC of LES. Result: These were 4 women and a man of an average age at diagnosis 51.8 years [43-58 years]. The mean duration of follow-up was 16.4 years. RA was initiator in three patients and two cases started with rhupus. Rhupus was associated with Gougerot Sjogren syndrome (n=3); anti-phospoholipid syndrome (n=2); primary biliary chirrosis (n=1) and leukocytoclastic vasculitis (n=1). Polyarthralgia was present in all of our patients; photosensitivity and malar rash in 2 patients. Two patients had Raynaud syndrm and arthritis. Hemolytic anemia with a positive CDT was noted in 2 patients. Hypergammaglobulinemia was noted in 3 patients. All of our patients had positive RF, anti CCP and ANA with titers ranged from 1/400 to 1/12,800. Three of our patients had positive anti native DNA. Two patients presented positif aCL and / or ACC and / or anti b2GPI. Anti-SSA were positif in 2 cases anti SSB (n =1) anti histone: (n =1) anti Sm (n=1) and anti RNP (n = 2). All of our patients were put on corticosteroid therapy and methotrexate and hydroxychloroquine was prescribed in 2 patients. Conclusion: Rhupus mainly concerns young women in the third decade.
