Virological efficacy in HIV-infected patients affected by non-Hodgkin lymphoma, treated with antiblastic chemotherapy and highly active antiretroviral therapy

This study evaluated replication of human immunodeficiency virus (HIV) and the genotypic resistance pattern in 26 HIV-infected patients affected by non-Hodgkin lymphoma who were treated with at least 3 cycles of chemotherapy (CT; rituximab and CDE) and highly active antiretroviral therapy (HAART). Genotyping was performed at baseline and when virological failure occurred. Six patients met the virological failure criteria. The genotyping analysis demonstrated that during CT administration new mutations might occur, but no significant changes in the pre-existing resistance patterns were observed. The data show that a combination therapy consisting of CT and HAART is feasible and that the virological response can be maintained in the majority of such patients.
