Observational Study
Rhupus syndrome: Description of 9 cases with special attention to the HLA-DR genotype.
Rhupus is a very rare syndrome of overlapping rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), characterized by the presence of erosive polyarthritis associated with symptoms and signs of SLE and the presence of high specificity autoantibodies. The analysis of HLA-DR molecules would allow us to genetically characterize patients diagnosed with rhupus, being able to differentiate them from the HLA-DR profile of patients with RA and SLE. ⋯ A higher proportion of HLA-DR1 and DR9 was observed in patients with rhupus compared to RA and SLE, as well as a lower proportion of HLA-DR2, DR6 and DR8, which would help the early characterization of these patients prior to the overlap diagnosis.

Tricuspid regurgitation (TR) induced by the implantation of cardiac implantable electronic devices (CIED) is an increasingly common cause of severe TR. Our aim was to describe the echocardiographic phenotypic characteristics of CIED-induced severe TR. ⋯ Our patients with CIED-induced severe TR are characterized by a heterogeneous phenotype with a high prevalence of severe RA and tricuspid annulus dilatation. RVGLS, RVFWLS, and arterial ventricular coupling were the most sensitive parameters for early assessment of RV systolic dysfunction.
