Filter by:This protocol will collect blood samples and medical information from patients who have had a bone marrow transplant using cells from an unrelated donor identified through the National Marrow Donor Program (NMDP). The NMDP has two programs in which patients can participate: the Research Database Program and the Research Sample Repository. Patients who have received a bone marrow transplant at the NIH or other institution from an unrelated donor affiliated with the NMDP may be eligible for this study. Participants in the NMDP Research Database program will have medical information about their disease and their transplant sent to the NMDP before and after the transplant and once a year for the rest of their life. The information will be used to help determine how well transplant recipients recover from their transplant, how recovery after a transplant can be improved, how access to transplant for different groups of patients can be improved and how well donors recover from collection procedures. Participants in the NMDP Research Sample Repository program will have a small blood sample drawn from a vein in the arm just before they start taking medicines for the conditioning regimen to prepare them for the transplant. The blood samples will be used to look at ways to improve how patients are matched with their donors, to determine and evaluate the factors that affect transplant outcome, and to help develop methods to improve tissue matching between donors and recipients.
his study will evaluate a series of problem-solving education sessions for patients undergoing a stem cell transplant and their family caregivers. The emotional stress of transplant extends beyond patients to their families, especially caregivers. Little is known about managing the emotional distress associated with stem cell transplant or the support and education most helpful to caregivers of stem cell recipients. Patients undergoing a stem cell transplant and their family caregivers may be eligible for this study. All participants must be 18 years of age and older. Patients and their caregivers receive routine treatment-specific education from transplant team members. This study adds a series of educational sessions focusing on problem-solving skills. In addition to the study education, participants do the following: - Complete a 130-item questionnaire when they consent to participate in the study. - Complete a 60-item questionnaire and attend a 60-minute face-to-face education session before the transplant. - Complete a 40-item questionnaire and attend a 60-minute face-to-face education session before hospital discharge. - Complete the same 40-item questionnaire and attend a 60-minute face-to-face education session 2 weeks after hospital discharge. - Attend a 30-minute face-to-face education session 4 weeks after hospital discharge. - Complete a 60-item questionnaire 6 weeks after hospital discharge.
The rationale for this protocol is based on the need to assess if the current post stem cell transplantation CMV prophylaxis strategies (e.g. high-dose acyclovir plus pre-emptive treatment) can be improved by the use of valganciclovir. CMV is the most common viral infection following stem cell transplantation, causing significant morbidity and mortality. Furthermore, CMV has been shown to be associated with a number of indirect effects in SCT recipients including allograft dysfunction, acute and chronic graft versus host disease (GVHD). Valganciclovir is shown to be more active than oral ganciclovir, and as good as intravenous (i.v.) ganciclovir in treating newly diagnosed CMV retinitis. The use of valganciclovir for CMV prophylaxis post stem cell transplantation was never tested in controlled study. The investigators therefore suggest a prospective, randomized study to evaluate the efficacy and safety of valganciclovir compared with acyclovir for prevention of CMV disease in allogeneic stem cell transplantation recipients.
Nutrition is an important part of the recovery process after having a head injury so that subjects can gain strength and fight off infection. Liquid nutrition formulas are often given to patients through a tube that has been placed into the intestines for feeding when they are unable to eat on their own. Some reports suggest that nutrition with extra amounts of the amino acid called glutamine may decrease infections and hospital stay in severely injured patients. The purpose of this study is to evaluate if giving extra amounts of an amino acid called glutamine with liquid nutrition formulas will decrease the risk of infection and length of stay in the intensive care unit after having a head injury.
A study to assess efficacy, safety and pharmacokinetics of a tacrolimus new oral formulation (MR4) in de novo bone marrow transplant recipients
To assess safety and efficacy of the patients with MR4 therapy in GVHD prophylaxis study who are eligible for the administration after 100 days post transplant (up to 1 year)
The main purpose of this study is to examine techniques to help patients cope better with the stem cell/bone marrow transplant procedure.
For children undergoing bone marrow transplantation, respiratory failure is a devastating complication, with mortality expectations well above 60%. The researchers have devised a novel strategy that may greatly improve survival. Hemofiltration, a continuous form of dialysis, was designed as a therapy for critically ill patients with kidney failure. A semi-permeable membrane removes plasma water and solutes (up to about 35,000 Daltons molecular weight). The researchers have treated immuno-compromised children with respiratory failure with hemofiltration. Many inflammatory molecules are of a size well below the limit of the filter. Hemofiltration might remove a critical amount of this inflammatory material, attenuating the unregulated inflammatory response that is central to the development of respiratory failure and progression to multiple organ failure and death. The researchers are conducting a multi-center trial of early continuous hemofiltration for respiratory failure in children following bone marrow transplantation. The researchers will analyze blood and ultrafiltrate using sensitive proteomic methods to detect several inflammatory biochemicals known to be active in this disease, looking for evidence that early active hemofiltration alters the inflammatory response. The researchers will test whether `early` hemofiltration produces greater survival from respiratory failure in this vulnerable population.
Shingles is an infection commonly seen in children with a weakened immune system (immunocompromised children). The immune system can be weakened as a result of medications that patients receive for cancer or other serious illness or as a result of a bone marrow transplantation. Shingles in children with a weakened immune system may spread throughout the body and in some instances may be life-threatening. Acyclovir is a medication that is routinely used to treat immunocompromised children with shingles in order to prevent further spread of their shingles and to help them heal faster. Acyclovir is also given to bone marrow transplant patients to prevent reactivation of HSV infection. Valacyclovir is a new drug that is metabolized (broken down in the body) to acyclovir. Valacyclovir is given by mouth and studies done in adults have shown it to be more effective than acyclovir given by mouth. The purpose of this study is to - study the pharmacology of this drug (how the body handles this drug), - determine if oral Valacyclovir can be safely given to children with shingles, and - determine the type of side effects that occur when oral Valacyclovir is given to immunocompromised children.
This study will look at how people cope with an upcoming bone marrow transplant and how personality characteristics influence coping styles in stressful medical situations. Personality traits, such as extraversion, optimism and self-esteem have been related to active, problem-focused coping styles, whereas neuroticism has been related to increased psychological distress and denial as a way of coping. Coping styles, in turn, have been related to disease outcome. For example, a fighting spirit and avoidance have been correlated with longer survival, whereas fatalism, anxious preoccupation and feelings of helplessness and hopelessness were related to a poor disease outcome. A better understanding of the relationship between coping styles and personality may help improve supportive care for people undergoing bone marrow transplants. This study will: - Explore the relationship between personality traits, coping styles and psychological stress in patients awaiting bone marrow transplantation - Identify what coping styles people use to prepare for bone marrow transplantation - Identify what personality traits are related to particular coping styles in patients awaiting bone marrow transplantation - Identify the relationship between personality factors and level of psychological distress in patients awaiting bone marrow transplantation Cancer patients 18 years of age and older who are scheduled for bone marrow transplant are eligible for this study. Participants will fill out pencil-and-paper questionnaires providing demographic information (such as age, gender, marital status, ethnicity, and so forth) and answering questions about their opinions and preferences. The information will be used to assess the participants' personality characteristics, coping styles, and psychological distress. The questionnaires take about 45 to 50 minutes to complete.
