Among them, LMP1 is essential for transformation. Rituximab is a potent agent used in the treatment of low grade B-cell lymphomas and is also widely used for the treatment of post-transplant lymphoproliferative disorders caused by EBV. The effect of rituximab treatment on the latent EBV infection in non-transplant patients with lymphoproliferative disorders has never been studied to our knowledge. Patients and Methods: We studied, the effect of rituximab-based immunochemotherapy on the EBV status of 44 patients with leukemic low grade B-cell lymphoma. Results: After three cycles of rituximab-based treatment, only 1/17 patients was still positive for EBV. Discussion: Our results suggest that rituximab used in the treatment of EBV-positive low-grade lymphoma is efficient in eradicating the virus from the peripheral blood, a fact with potential implications in the course and prognosis of the disease.
