Persistent Sydenham’s chorea is not associated with sustained lymphocyte dysfunction

The mechanisms involved in the symptoms of Sydenham’s chorea (SC) remain obscure. Taking into account the autoreactive antibody-mediated hypothesis of SC pathogenesis, the persistence of chorea may be associated with increased levels of B1 lymphocytes and other lymphocyte subsets. We evaluated lymph...

description The mechanisms involved in the symptoms of Sydenham’s chorea (SC) remain obscure. Taking into account the autoreactive antibody-mediated hypothesis of SC pathogenesis, the persistence of chorea may be associated with increased levels of B1 lymphocytes and other lymphocyte subsets. We evaluated lymphocyte subsets, including B1 and T cells, in patients with remitted (RSC) and persistent (PSC) SC by flow cytometry. Our results showed neither difference in the frequency of T and B lymphocytes subpopulations nor in their activation and functional states. These findings undermine the view of PSC as a sustained cytotoxic cellular-mediated condition. Alternative mechanisms may explain the pathogenesis of PSC.
