[Case report: RAEB in a patient with rheumatoid arthritis treated with methotrexate and infliximab].

Anti TNF-alpha drugs seem to be the new frontier of Rheumatoid Arthritis (RA) therapy. The association infliximab methotrexate has been approved for the treatment of RA not responding to the classic therapy, but the short clinical experience in using antiTNF-alpha molecules brings to segnalation of new risks or adverse events. We describe a case of a patient, treated for many years with classic RA therapy, which developed a refractory anemia after treatment with association infliximab-methotrexate.
