Rituximab is a monoclonal antibody intended for the treatment of various autoimmune conditions as well as B-cell lymphoid malignancies. It is targeted to the CD20 antigen, which induces apoptosis in mature B cells, making it a useful therapeutic agent against B-cell lymphoid malignancies when used in conjunction with cytotoxic chemotherapy regimens such as cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin (vincristine; Hospira Inc, Lake Forest Ill), and prednisone/prednisolone. It is a very successful treatment of B-cell malignancies but causes profound immunosuppression and elevates the risk of opportunistic infections such as enterovirus meningitis. We report a case of aseptic meningitis in a patient with non-Hodgkin lymphoma after treatment with rituximab in combination with cytotoxic chemotherapy and successful treatment with intravenous immunoglobulin therapy.
Prolonged periods of B-cell deficiency caused by rituximab increases the risk for infections by attacking the antibodies which are the body’s natural protection against some of the viral infections such as enterovirus. Givens et al. report a case of persistent enterovirus meningoencephalitis in patient with NHL after rituximab therapy. The patient was successfully treated with intravenous immunoglobulin with complete resolution of the symptoms.
