Brief summary: This clinical trial studies gene-modified, human immunodeficiency virus (HIV)-protected stem cell transplant in treating patients with HIV-associated lymphoma. Stem cells, or cells which help form blood, are collected from the patient and stored. They are treated in the laboratory to help protect the immune system from HIV. Chemotherapy is given before transplant to kill lymphoma cells and to make room for new stem cells to grow. Patients then receive the stem cells that were collected from them before chemotherapy and have been genetically modified to replace the stem cells killed by the chemotherapy.

Detailed description: PRIMARY OBJECTIVES:

I. To assess the safety and feasibility of infusing gene-modified, HIV-protected hematopoietic stem/progenitor cells (HSPC) after high-dose chemotherapy for treatment of acquired immune deficiency syndrome (AIDS)-related lymphoma.

II. To observe the change in gene-modified cell levels before and after antiviral treatment interruption.

SECONDARY OBJECTIVES:

I. To evaluate the molecular and clonal composition of gene-modified cells after hematopoietic cell transplant (HCT).

II. To describe time to disease progression, progression-free survival, treatment-related mortality, time to neutrophil and platelet recovery, and incidence of infections.

TERTIARY OBJECTIVES:

I. To evaluate the effect of procedure on HIV-specific immune reconstitution.

II. To observe the effect of HIV infection on the presence of gene-marked cells as determined by deoxyribonucleic (DNA) polymerase chain reaction (PCR).

OUTLINE:

CONDITIONING: Patients undergo high-dose chemotherapy or chemoradiotherapy according to institutional guidelines.

STEM CELL INFUSION: Patients undergo hematopoietic stem cell transplant with LVsh5/C46 (Cal-1) transduced autologous CD34+ hematopoietic stem/progenitor cells (HSPC) on day 0.

Note: Patients continue to receive highly active antiretroviral therapy (HAART) throughout treatment, with a 7-day break for apheresis. Patients may be eligible for a structured treatment interruption of up to 12 weeks after autologous hematopoietic stem cell transplant with gene-modified cells.

After completion of study treatment, patients are followed up periodically for 2 years, every 6 months for 3 years, and then annually for 15 years post-HCT.

Eligibility criteria: Inclusion Criteria:

* HIV-1 seropositive
* Stable, continuous antiretroviral treatment for at least three months before enrollment, defined as a multi-drug regimen (excluding azidothymidine \[AZT\])
* HIV plasma viral load \< 50 copies/ml
* Non-Hodgkin or Hodgkin lymphoma without active central nervous system (CNS) involvement associated with poor prognosis with medical therapy alone or for which autologous peripheral blood stem cell (PBSC) transplant is indicated:

  * Hodgkin's lymphoma beyond first remission or first partial remission or induction failure with subsequent response to salvage therapy
  * Non-Hodgkin's lymphoma beyond first remission or first partial remission or induction failure with subsequent response to salvage therapy
  * Chemotherapy responsive disease
* Karnofsky performance score \>= 70%
* Subjects must agree to use effective contraception from enrollment through completion of the study
* Female subjects: if of child bearing potential, must have negative serum or urine pregnancy test within 7 days of enrollment
* Subjects must be on a prophylactic regimen for pneumocystis carinii pneumonia, or agree to begin such treatment, if CD4+ cell counts are observed to be =\< 200/ul in peripheral blood
* Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

* Renal disease: serum creatinine \> 2 times upper limit of normal
* Liver disease: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than 3 times the upper limits of normal, unless determined to be a result of the primary hematologic malignancy
* Serum bilirubin greater than 3 times the upper limit of normal, unless attributed to Gilbert's syndrome
* Pulmonary disease: forced vital capacity (FVC) \< 60% predicted
* Pulmonary disease: forced expiratory volume in 1 second (FEV1) \< 60% predicted
* Pulmonary disease: diffusion capacity of the lung for carbon monoxide (DLCO) parameters \< 60% predicted (corrected for hemoglobin)
* Cardiac insufficiency: left ventricular ejection fraction (LVEF) \< 50% or coronary artery disease requiring treatment
* Active infection requiring systemic antibiotic therapy with antibacterial, antifungal, or antiviral agents (excluding HIV)
* Hepatitis B surface antigen positive
* Hepatitis C virus (HCV) antibody positive and detectable HCV quantitative ribonucleic acid (RNA) with clinical evidence of cirrhosis
* Requiring active treatment for Toxoplasma gondii

* Malignancy other than lymphoma, unless (1) in complete remission and more than 5 years from last treatment, or (2) cervical/anal squamous cell carcinoma in situ or (3) superficial basal cell and squamous cell cancers of the skin
* History of HIV-associated encephalopathy; dementia of any kind; seizures in the past 12 months; any perceived inability to directly provide informed consent (Note: Consent may not be obtained by means of a legal guardian)
* A medical history of noncompliance with HAART or medical therapy
* Any concurrent or past medical condition that, in the opinion of the Investigator, would exclude the subject from participation or any psychosocial conditions that would hinder study compliance or follow-up, at the discretion of the Investigator
* Receipt of a vaccine for HIV-1 or any prior gene modified cell product, at any time
* Known hypersensitivity to any of the products used in the trial-G-CSF (Neupogen), plerixafor, or any planned components of conditioning regimens
* Pregnant or nursing women
