Brief summary: This pilot clinical trial studies biological therapy in treating patients with acquired immune deficiency syndrome (AIDS)-related lymphoma undergoing stem cell transplant. Giving chemotherapy before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood and stored. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving biological therapy as part of the stem cell transplant may be more effective in treating patients with AIDS-related lymphoma

Detailed description: PRIMARY OBJECTIVES:

I. To determine the safety and feasibility of using lentivirus-transduced hematopoietic progenitor cells (HPCs) (lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells) in the setting of autologous hematopoietic cell transplantation (HCT) for treatment of AIDS related lymphoma. The safety of the of the genetically modified product used in the transplant procedure will be assessed by monitoring each subject for adverse events (procedure related toxicity); absolute neutrophil count (ANC)/platelet engraftment (sustained recovery); and evidence of replication competent vector or vector recombination with the human immunodeficiency virus (HIV) quasi-species present in the patient.

II. To determine the quantity and duration of vector-marked peripheral blood cells and to characterize: the duration and level of gene marking and expression of the anti-HIV ribonucleic acids (RNAs) in these transduced cells, and the characterization of the integration sites of vector sequences in circulating cells if there is a clinical syndrome suggestive of a clonal expansion of hematopoietic cells. In addition, the feasibility of the process will be assessed based on the results of the release testing of the transduced cells prior to injection into the patient.

III. To determine whether the design of the vector prevents vector mobilization and rescue by wild-type HIV-1. IV. To measure the effect of HIV infection on the presence of HIV-resistant blood cells as measured by genetic marking for vector sequences before and after antiviral treatment interruption.

OUTLINE:

CONDITIONING: Patients receive carmustine intravenously (IV) over 1-2 hours on days -7 to -5, etoposide IV over 4 hours on day -4, and cyclophosphamide IV on day -2.

TRANSPLANTATION: Patients undergo autologous hematopoietic stem cell transplantation comprising lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells and non-bound cluster of differentiation (CD)34+ cells IV on day 0. After completion of study treatment, patients are followed up every 2 weeks for 3 months; at 4, 6, 8, 10, 12, 18, and 24 months; every 6 months for 3 years; and then annually for 10 years.

Eligibility criteria: Inclusion Criteria:

* HIV seropositive at or before the time of lymphoma diagnosis
* Anti-HIV chemotherapy; subjects must be on a multi-drug regimen (excluding azidothymidine) and have an HIV viral load \< 50,000 copies/ml by reverse transcriptase-polymerase chain reaction (RT-PCR) at the time of study enrollment
* Subjects must agree to have their anti-HIV regimen temporarily stopped, and then all subjects will stop antiretroviral therapy (ART) for approximately 7 days at the time they start filgrastim (G-CSF) post-chemotherapy for peripheral blood progenitor cell (PBPC) mobilization and until the mobilization is complete; in addition, if/when the CD4 counts return to a level of 450/mm\^3 with undetectable HIV levels in blood, the subjects will undergo an analytic treatment interruption for an indefinite period not to exceed 6 months
* Karnofsky performance status \>= 70%
* Biopsy proven intermediate grade or high-grade non-Hodgkin's lymphoma, including plasmablastic lymphoma, primary effusion lymphoma, or biopsy-proven Hodgkin's lymphoma (entities as defined in the World Health Organization \[WHO\] classification); tissue histology will be reviewed at the City of Hope; patients with prior marrow involvement must demonstrate =\< 10% involvement pre-stem cell collection

* Patients who are hepatitis C virus (HCV) antibody positive or hepatitis B virus (HBV) surface antigen positive must be free of clinical evidence of cirrhosis that would otherwise make them ineligible for HCT, as determined by the Principal Investigator (PI) in consultation with the Gastrointestinal Service at City of Hope; patients with HBV and ongoing evidence of viral replication may require therapy prior to receiving high-dose chemotherapy
