Immune Response After Stem Cell Transplant in HIV-Positive Patients With Hematologic Cancer

PRIMARY OBJECTIVES:

I. Examine the development of donor-derived HIV-1-specific immune response following
hematopoietic cell transplant (HCT) for treatment of hematologic malignancy in HIV+
patients.

II. Examine the affect of HCT on the pool of latently infected cluster of differentiation
(CD)4+ T cells in HIV+ patients given HCT for treatment of hematologic malignancy.

OUTLINE:

Patients undergo leukapheresis for analysis of HIV-1 latent reservoir at baseline and at
days +90, +180, +365, and +730, and then annually thereafter as feasible.

Inclusion Criteria:

- HIV positive

- Treatment with highly active antiretroviral therapy (HAART) for at least 1 month

- Viral load has decreased by >= 1.5 logs or viral load < 5000 copies/ml plasma on
HAART therapy

- Hematologic malignancy associated with a poor prognosis or other diagnosis for which
hematopoietic cell therapy (allogeneic or autologous, including gene therapy) is
indicated

- Approval for allogenic regimen given at Patient Care Conference

- DONOR: Autologous or allogeneic gene modified cells allowed

Exclusion Criteria:

- A medical history of noncompliance with HAART or medical therapy

- Inability to provide informed consent

- DONOR: Allogeneic donors must not have HIV infection
