Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.展开更多

We present the first series of rhupus in Niger. Observation 1: This is a patient suffering from chronic polyarthritis in whom the diagnosis of active seropositive, erosive and deforming RA had been made according to the 1987 ACR criteria and SLE on the presence of 4 criteria according to the 1997 ARA criteria and putting under conventional synthetic DMARDs. The outcome was favorable with a remission achieved after 8 weeks with a disease activity score (DAS) 28 at 2.2. Observation 2: 58-year-old patient with known diabetes type 2 in whom the diagnosis of rhupus was made according to the ACR/EULAR 2010 criteria for RA with a DAS28 of 3.6 and the 2019 LES criteria at 18 points with a SLEDAI score of 6. The evolution was marked by the occurrence of a myocardial infarction with a favorable outcome under medical management. Conclusion: Rhupus is a rare entity that can be complicated by cardiovascular events with the presence of an independent cardiovascular risk factor.展开更多
