Active clinical trials for "Leukopenia"

Patients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS

The majority of cases of autoimmune cytopenias, which includes immune thrombocytopenia (ITP), autoimmune hemolytic anemia, autoimmune neutropenia (AIN) and pure red cell aplasia, will respond to conventional immunosuppressive therapy with or without splenectomy. There is, however, a group of patients with refractory or chronically relapsing autoimmune cytopenias causing life-threatening hemorrhages, infections or anemia. Further problems include the short- and long-term side-effects of corticosteroids, and the potential toxicity of immunosuppressive and cytotoxic agents. An alternative and less toxic approach in these patients may be the treatment with Campath-1H, a humanized IgG monoclonal antibody specific for the CD52 antigen and present on human lymphocytes and monocytes. The main effect of Campath-1H is on T cell and it results in a prolonged and profound depletion of the CD4 and CD8 subpopulations, particularly the CD4 population, and this might "reset" the immune system without the need for total immune ablation.Therefore, this study is designed to investigate safety and efficacy of repeated Campath treatment cycles in autoimmune cytopenia.In order to minimize possible side effects of accumulating Campath, the 3 treatment cycles will be administered in consecutively reduced doses.

This phase I trial studies the side effects and best dose of iodine I 131monoclonal antibody BC8 when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, and donor bone marrow transplant, and to see how well they work in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia that has spread to nearby or other places in the body (advanced), or high-risk myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. Also, radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide together with mycophenolate mofetil and tacrolimus after the transplant may stop this from happening. Giving a radiolabeled monoclonal antibody together with donor stem cell transplant, fludarabine phosphate, cyclophosphamide, mycophenolate mofetil, and tacrolimus may be an effective treatment for advanced acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes.

The primary objective of the study is to determine the safety and tolerability when adding abatacept to acute Graft versus Host Disease in transplants for malignant diseases using unrelated donor bone marrow or peripheral blood stem cell grafts.

To determine the safety, immunogenicity, biological activity, ad pharmacokinetics of sargramostim ( recombinant granulocyte-macrophage colony-stimulating factor; GM-CSF ) human granulocyte-macrophage colony-stimulating factor ( GM-CSF ), given by subcutaneous ( SC ) injection to patients with leukopenia in association with HIV infection.

The purpose of this study is to evaluate the safety and efficacy of the sequential infusion of allogeneic mesenchymal stem cells (MSC), expanded "in vitro" with platelet lysate without addition of animal products in the treatment of patients undergoing allo-HSCT who developed one or more cytopenias.

This phase II trial studies the side effects and best dose of total-body irradiation when given together with fludarabine phosphate followed by a donor peripheral stem cell transplant in treating patients with myelodysplastic syndromes (MDS) or myeloproliferative disorders (MPD). Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

To determine the safety, tolerability and maximum tolerated dose of SDZ ILE 964 administered by daily subcutaneous injections in patients infected with human immunodeficiency virus (HIV) who have cytopenias (low blood cell counts). To obtain information about the biologic effects of SDZ ILE 964 administration in improving blood counts in HIV-infected patients. To obtain information about the effects of SDZ ILE-964 administration on both parameters of HIV replication and on residual immunologic function.

Many breast cancer patients will taking Chinese herbal medicine during receiving radiotherapy. The investigators conducted the pilot study showing Compound Herbal Formula (TPE-1) have the effect of improving the fatigue and leukopenia during radiotherapy. So the investigators designed this double blind and controlled trial to evaluate whether TPE-1 have the effects for leukopenia and cancer-related fatigue in breast cancer patients with radiotherapy. From our initial observation for 2 years, TPE-1 is safety. The study is also designed to evaluate the safety when patients taking this formula.

BACKGROUND: One couple out of 6 consults for infertility during their sexual life. In 60% of cases a male factor is associated or is the main infertility factor. Inflammatory Syndrome (IS), characterized by the presence of a leukocytospermia is found in 12% of the cases. Leukocyte degranulation causes oxidative stress (OS) through the formation of free radicals attacking the sperm cell functions. HYPOTHESIS: To establish the responsibility of the IS, and OS, in chronicle inflammatory male infertility, the investigators hypothesize that its treatment (as well as its possible cause) must restore or improve the fertilizing capacity of patients sperm. METHODS: This prospective randomized study will test the response to the treatment. The investigators shall measure cellular degradation products due to the OS, thereby certifying that it does have a deleterious effect on sperm cell. Seminal biochemistry will also assess the impact of the syndrome on the genital tract glands and follow its evolution. The patients will be included in the study as soon as the leukocytospermia will be > 0,5*106/ml or as soon as the elastase will be > 500 ng/mL. The examinations will be performed using flow cytometry, CASA (Computer Assisted Semen Analysis). The analysis of sperm morphology will be centralized. Primary endpoint will be a reduction in the percentage of 8OH-dG below 35 %. We anticipate that it should arrive to 20 % of the patients included in the arm treatment by corticosteroid therapy. All in all will thus be needed 50 patients in the group placebo and 50 in the group treated. Secondary endpoint the improvement of the spermatic parameters and the reduction of the fragmentation of the DNA of sperm cells to the treated subjects. All these biological markers will be evaluated 6 month after the treatment: Fragmentation of the spermatic DNA below 37 % during the follow-up in 6 months Leukocytospermia and elastase Seminal biochemistry Other markers of the inflammatory syndrome and oxidative stress (protein carbonyl, 8OHd-Guanosine) Possibly the radiological examinations (Ultrasound and MRI of the genital tract) In addition it would allow us to propose a policy of prevention towards acquired post-infectious male infertility.
