Official title

Evaluation of Systemic Toxicity Associated With Allogeneic Peripheral Blood Stem Cell Infusion

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will try to determine what causes toxic side effects of stem cell transplantation, such as increased blood pressure, increased heart rate, decreased kidney function and abnormal heart rhythms. Stem cells are used to treat various diseases, including cancer, aplastic anemia and sickle cell disease. The cells may be given fresh to the patient or they may be preserved first with a chemical called DMSO and frozen for later use. Some stem cell transplant procedures include infusion of red blood cells along with the stem cells. This study will examine whether side effects of stem cell transplants are associated with the DMSO preservative in frozen cells or with hemoglobin (a protein released from defrosted red blood cells) or neither of these factors. Healthy volunteers and patients scheduled to receive a stem cell transplant may be eligible for this study. Candidates must be between 10 and 80 years of age. Transplant patients will undergo a stem cell transplant. The cells are infused through a catheter placed in a vein for the procedure. Depending on the patient s requirements, the infusion may or may not include red blood cells and may or may not contain DMSO. Healthy volunteers undergo a 4-hour saline infusion. The saline (water mixed with salt) is infused through a catheter (plastic tube) placed in a vein in the arm. In addition, all participants have the following tests and procedures: * Heart monitoring: Healthy volunteers wear a portable heart monitor, attached to the chest using four stickers, for 24 hours starting the morning of the infusion. Transplant patients wear the same device for 48 hours, starting the morning before the infusion. * Blood draws and urine collections before, during, just after and the morning after the infusion of saline or stem cells. * Heart ultrasound before, during or just after and the morning after the infusion. * Peripheral artery tonometry: A small cup is placed on one finger of each hand to measure blood flow in the finger. A blood pressure cuff is inflated around the lower arm and tight pressure is maintained for about 5 minutes.
