Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
All volunteers may be normal volunteers or have a diagnosis of a lymphoid/hematologic malignancy (chronic myelogenous leukemia, multiple myeloma, lymphoma, acute myelogenous leukemia, chronic lymphocytic leukemia, acute lymphocytic leukemia).
To be eligible peripheral blood apheresis, all normal volunteers must have a hematocrit of greater than or equal to 36% and a peripheral platelet count of greater than or equal to 100,000/mm(3). Volunteers with a lymphoid/hematologic malignancy must have a hematocrit of greater than or equal to 30% and a peripheral platelet count of greater than or equal to 100,000/mm(3). All volunteers, including those volunteers with lymphoid/hematologic malignancies, must have a white blood cell count of greater than or equal to 4,000/mm(3). Volunteers with a lymphoid/hematologic malignancy must have a white blood cell count of less than 100,000/mm(3).
To be eligible for venipuncture or bone marrow aspiration, normal volunteers and volunteers with lymphoid/hematologic malignancies must have no history of an abnormal bleeding tendency or documented predisposition to infection. For venipuncture and bone marrow aspiration, the peripheral blood platelet count of normal volunteers must be greater than 100,000/mm(3) and for volunteers with a lymphoid/hematologic malignancy, the platelet count must be greater than or equal to 50,000/mm(3).
All normal volunteers and volunteers with a lymphoid/hematologic malignancy are eligible to receive apheresis (done only at the NIH Clinical Center), bone marrow sampling, or venipuncture. Apheresis will only be performed at the Clinical Center of the National Institutes of Health. Apheresis will not be peformed at collaborating institutions.
Normal volunteers and volunteers with lymphoid/hematopoietic malignancies may donate samples by apheresis, venipuncture, and bone marrow sampling on multiple occasions. Repeated donation by apheresis will be allowed as long as a period of at least eight week has elapsed since a previous apheresis. Repeated donations of peripheral blood or bone marrow will be allowed as long as a period of at least four weeks has elapsed since a previous donation. For any given volunteer, the total number of aphereses will not exceed six per year and the total number of peripheral blood or bone marrow donations will not exceed eight per year. All normal and CML volunteers must undergo repeat physical examination and complete blood count evaluation to determine eligibility prior to donation.
Normal volunteers and volunteers with lymphoid/hematologic malignancies will not be tested for HIV or hepatitis to determine eligibility for this protocol. However, DTM guidelines will require that patients undergoing apheresis with subsequent ex vivo elutriation of the collected products will be required to have testing for HIV and hepatitis B and C. Volunteers who are required to be tested for HIV and Hepatitis will be informed at the time of enrollment and will sign an appropriate informed consent for these tests. Volunteers who are found to be HIV positive or hepatitis B or C can still donate blood products, but these products will not be subjected to ex vivo elutriation.
Volunteers with lymphoid/hematologic malignancies may be receiving therapy such as chemotherapy or chronic interferon alpha injections.
Exclusion Criteria
Any normal volunteer or volunteer with a lymphoid/hematologic malignancy with a known history of HIV or hepatitis B or C will be ineligible.
Any normal volunteer or volunteer with a lymphoid/hematologic malignancy requiring chronic anticoagulation or steroid therapy will be ineligible.
Any volunteer with a lymphoid/hematologic malignancy with a peripheral blast count that exceeds 25% or a total lymphocyte count that exceeds 100,000/mm(3) will be ineligible for apheresis.
Volunteers with a lymphoid/hematologic malignancy who are currently enrolled in an experimental therapy on an NCI protocol will be ineligible.
Any normal volunteer or volunteer with a lymphoid/Hematologic malignancy with known AIDS and/or hepatitis B or C will be excluded.
Volunteers with a history of diabetes mellitus will be excluded from receiving \[6,6-(2)H\] or \[U-(13)C9\]-glucose infusions.
A pregnancy test will be given to all female volunteers and volunteers who are pregnant will be excluded from the study.
