Abstract

We herein report the case of a 69-year-old woman with rheumatoid arthritis (RA) and malignant lymphoma who developed Helicobacter cinaedi bacteremia after starting rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy. She had a recurrent fever and painful erythema for 13 months before the diagnosis was made. This delayed diagnosis was attributable to the underlying RA, which typically presents with various cutaneous manifestations and elevated C-reactive protein levels. The erythema on the thighs, abdomen, and left forearm improved following treatment with intravenous aminobenzyl penicillin; she received antibiotics for six weeks. This case emphasizes the importance of recognizing this opportunistic infection in immunocompromised patients.
