Sirolimus Treatment for Newly Diagnosed Primary Acquired PRCA

Pure Red Cell AplasiaAcquired

Pure red cell aplasia (PRCA) is a kind of anemia characterized by severe reticulocytopenia and obvious bone marrow erythroblastic cells decreased. Cyclosporine A and /or steroids are the first line therapy but some patients were refractory or intolerance to the treatment. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of sirolimus for newly diagnosed primary acquired PRCA.

AnemiaChronic Kidney Disease2 more

The purpose of this study is to evaluate the ability of peginesatide (AF37702) to increase and maintain increased hemoglobin levels in participants with chronic kidney disease (CKD) (either not on dialysis, receiving regular hemodialysis or peritoneal dialysis, or following renal transplant) with confirmed antibody-mediated pure red cell aplasia (PRCA).

Pilot Phase I/II Study of Amino Acid Leucine in Treatment of Patients With Transfusion-Dependent...

Diamond Blackfan AnemiaBlackfan Diamond Syndrome3 more

This study will determine the safety and possibility of giving the amino acid, leucine, in patients with Diamond Blackfan anemia(DBA)who are on dependent on red blood cell transfusions. The leucine is expected to produce a response in patients with DBA to the point where red blood cell production is increased. Red cell transfusions can then be less frequent or possibly discontinued. The investigators will study the side effects, if any, of giving leucine to DBA patients. Leucine levels of leucine will be obtained at baseline and during the study. The drug leucine will be provided in capsule form and taken 3 times a day for a total of 9 months.

Stem Cell Transplantation (SCT) for Genetic Diseases

ThrombocytopeniaMetachromatic Leukodystrophy4 more

OBJECTIVES: I. Ascertain whether stem cell transplantation (SCT) is an effective method by which missing or dysfunctional enzymes can be replaced in patients with various inborn errors of metabolism. II. Determine whether clinical manifestations of the specific disease may be arrested or reversed by this treatment.

Sirolimus Treatment for Refractory PRCA

Pure Red Cell Aplasia

Pure red cell aplasia (PRCA) is a kind of anemia characterized by severe reticulocytopenia and obvious bone marrow erythroblastic cells decreased. Cyclosporine and /or steroids are the first line therapy but some patients were refractory or intolerance to the treatment. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of sirolimus for refractory PRCA.

NeutropeniaSickle Cell Anemia3 more

OBJECTIVES: I. Determine the efficacy of bone marrow transplantation using matched related donors in patients with nonmalignant hematologic disorders. II. Determine the quality of life, absence of adverse effects (e.g., graft versus host disease and B cell lymphoproliferative disease), and completeness of recovery of their underlying condition in these patients with this treatment regimen.

Tacrolimus Treatment for Refractory PRCA

Pure Red Cell Aplasia

Pure red cell aplasia (PRCA) is a kind of anemia characterized by severe reticulocytopenia and obvious bone marrow erythroblastic cells decreased. Cyclosporine and /or steroids are the first line therapy but some patients were refractory or intolerance to the treatment. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of tacrolimus for refractory PRCA.

Tacrolimus Treatment for Refractory Autoimmune Cytopenia

Autoimmune Hemolytic AnemiaPure Red Cell Aplasia1 more

Autoimmune cytopenia, including autoimmune hemolytic anemia (AIHA), pure red cell aplasia (PRCA), Evans syndrome (ES), usually has good responses to steroids therapies as first line, but there is a considerable percentage of patients who relapse, become refractory or dependent on steroids to maintain an acceptable level of hemoglobin or platelets. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of tacrolimus for refractory autoimmune cytopenia.

PurpuraSchoenlein-Henoch15 more

OBJECTIVES: I. Determine whether there is prompt engraftment after autologous peripheral blood stem cell transplantation using filgrastim (G-CSF) mobilization in patients with life threatening autoimmune diseases. II. Determine the kinetics of T- and B-cell immune reconstitution after a combination of timed plasmapheresis, high dose cyclophosphamide and total lymphoid irradiation, and posttransplant immunosuppression with cyclosporine in these patients. III. Determine whether this treatment regimen beneficially influences the clinical course of these patients.

Surveillance Study to Estimate the Incidence of Pure Red Blood Cell Aplasia Among Patients With...

Pure Red-Cell AplasiaChronic Kidney Failure

The purpose of this study is to estimate the incidence rate of pure red cell aplasia (PRCA; aplastic anemia) mediated by erythropoietin (EPO) antibodies in patients who are receiving subcutaneous (s.c.) epoetin alfa (polysorbate 80 formulation) for the treatment of anemia associated with chronic renal failure (CRF), and to compare this incidence rate to the incidence rate with s.c. exposure to other currently marketed recombinant erythropoietin products (epoetin alfa, epoetin beta, darbepoetin alfa), with adjustment of duration for which the drug is given to the patient. The study will also examine the impact of the pattern of using mixed s.c. exposure to multiple erythropoietin products occurring in this patients, and the impact of the time from which the treatment is started to the onset of PRCA.
