[Rituximab for treatment of Felty’s syndrome].

Felty’s syndrome is a rare variant of severe seropositive rheumatoid arthritis with neutropenia and splenomegaly. It is difficult to treat and associated with a poor prognosis due to the substantial risk of infections. This article presents the case of a patient with refractory disease who responded to rituximab with permanent normalization of neutrophil counts. Repeated infusions were necessary to induce and maintain remission.
