Plasmablastic lymphoma achieving sustained remission with antiretroviral therapy alone

Abstract

Despite advances in the treatment of most human immunodeficiency virus (HIV)-related lymphomas, the outcomes for patients with HIV-related plasmablastic lymphoma (PBL) remain poor. While studies have shown an increased survival for patients with most kinds of HIV-related lymphomas since the introduction of highly active antiretroviral therapy (HAART), the impact of HAART on survival in patients with HIV-related PBL is unclear, mainly because the condition is rare and the number of published studies is small. Few case reports have shown regression of PBL after initiation of HAART, however, usually followed by recurrence of PBL or achieved with a need for chemotherapy. We report the first case of PBL in a 38-year-old man with newly diagnosed HIV who achieved sustained remission after the initiation of HAART alone and who remains in remission seven years after diagnosis, without a need for chemotherapy or radiation. We illustrate the importance of initiating HAART therapy under the supervision of infectious disease specialists as soon as the PBL is diagnosed until future studies provide clear evidence in the management of HIV-related PBL.
