Active clinical trials for "Preleukemia"

Myelodysplastic syndromes (MDS) is a group of heterogeneous diseases characterised by the clonal evolution of dysplastic hematopoietic stem cells. This evolution is associated with accumulation of cytogenetic mutations which leads to acute myeloid leukaemia (AML). Evolution of MDS is also associated with increase of reactive oxygen species (ROS). The increase of ROS is associated with accumulation of cytogenetic mutations. Ascorbic acid (AA) is an actor of the regulation of the oxidative metabolism in the human body. Studies showed that supplementation with AA can change the proliferation status of MDS cells. Adjuvant treatment with AA is associated with a beneficial effect on the evolution of MDS and AML. The present study aim at describing the variations of plasmatic ascorbic acid concentrations between healthy volunteers and patients with myelodysplastic syndromes advanced in their treatment or recently diagnosed during a follow-up of 12 months.

The primary objective of this trial is as follows: To determine the pharmacokinetics of micafungin given twice weekly in patients at risk for developing an invasive fungal disease (patients who are being treated for acute or chronic graft versus host disease; patients receiving reduced intensity conditioning for Stem Cell Transplant (SCT); receiving first remission induction chemotherapy for Acute Myeloid Leucaemia (AML)/MyeloDysplasticSyndrome (MDS)) compared to the pharmacokinetics of micafungin given daily. The secondary objective of this trial is as follows: To determine whether adequate exposure of micafungin is attained. To determine the safety of micafungin in this patient population

This phase II trial studies how well early discharge and outpatient care works in patients with myelodysplastic syndrome or acute myeloid leukemia previously treated with intensive chemotherapy. Gathering information about patients with myelodysplastic syndrome or acute myeloid leukemia who are discharged after finishing chemotherapy, or who stay in the hospital until blood counts return to normal, may help doctors learn more about the safety of allowing patients to leave the hospital early, the patient's quality of life, use of medical services, and the cost of these services associated with such a policy.

RATIONALE: Lithium carbonate may be an effective treatment for intestinal graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying lithium carbonate in treating patients with acute intestinal graft-versus-host-disease after donor stem cell transplant.

RATIONALE: Rasburicase may be an effective treatment for graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying how well rasburicase works in preventing graft-versus-host disease in patients with hematologic cancer or other disease undergoing donor stem cell transplant.

RATIONALE: Ondansetron may help lessen or prevent nausea and vomiting in patients undergoing stem cell transplant. PURPOSE: This phase II trial is studying how well ondansetron works in preventing nausea and vomiting in patients undergoing stem cell transplant.

RATIONALE: American ginseng may reduce fatigue in patients with cancer. It is not yet known whether American ginseng is more effective than a placebo in treating cancer-related fatigue. PURPOSE: This randomized phase III trial is studying American ginseng to see how well it works in treating patients with fatigue caused by cancer.

RATIONALE: Tests that measure certain changes in blood in patients at high risk of cytomegalovirus infection may help doctors learn more about predicting cytomegalovirus infection after donor stem cell transplant. PURPOSE: This clinical trial is studying tests that measure changes in the blood in patients at high risk of cytomegalovirus infection after undergoing donor bone marrow transplant or peripheral stem cell transplant.

This is a non-blinded, non-randomized pharmacokinetic study to determine the oral bioavailability of clofarabine, and the effect of cimetidine on clofarabine pharmacokinetics in patients with poor-risk acute leukemias and myelodysplastic syndrome (MDS).

RATIONALE: Listening to relaxing music during a bone marrow biopsy may be effective in reducing anxiety and pain. PURPOSE: This randomized clinical trial is studying how well music works in reducing anxiety and pain in adult patients undergoing bone marrow biopsy for hematologic cancers or other diseases.
