Active clinical trials for "Lymphoproliferative Disorders"

This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.

Multi-site, prospective performance study to determine equivalency between the investigational CLPD Limited Panel on the FACSLyric system versus the final clinical diagnosis.

The purpose of this study is to better understand the genetic causes of Hodgkin's disease (a kind of lymphoma) and non-Hodgkin's lymphoma, as well as multiple myeloma, leukemia, and related diseases. The doctors have identified the patient because 1) they have had a lymphoproliferative disorder such as lymphoma, leukemia, or multiple myeloma, and have a family member with one of these disorders or 2) they are a member of a family with a lymphoproliferative disorder, including Hodgkin's disease and/or, non-Hodgkin's lymphoma or a second cancer after Hodgkin's disease.

The purpose of this study is to investigate possible genetic factors that contribute to the development of lymphomas. The databank will be used to determine whether familial lymphomas have unique genetic characteristics different from sporadic lymphomas and to attempt to identify a gene that confers an increased risk of lymphoma.

The purpose of the protocol is to allow for patients, and relatives of patients, who may have the newly described autoimmune lymphoproliferative syndrome, to be evaluated at the NIH Clinical Center. This evaluation will include blood and relevant tissue studies along with long-term clinical evaluations to define the biology, inheritance,clinical spectrum, and natural history of this syndrome. The aim of the research is to understand mechanisms involved in the development of expanded numbers of what is typically a rare population of immune cells (CD4-8-/TCRalpha/beta+ T cells, otherwise referred to as double negative T cells), and how these relate to the development of expanded numbers of immune cells and autoimmune (self against self) responses in patients with ALPS. In some cases, we may proivide treatment related to ALPS. These treatments are consistent with standard medical practice. Participants with ALPS will be invited to visit the NIH once a year or more frequently when clinically indicated for the next few years for clinicians and scientists to follow the course of their disease and to manage its complications. Knowledge gained from these studies provides important insights into the mechanisms of autoimmunity, the thymus gland, and the role that the immune system and genetics plays in ALPS. Autoimmune lymphoproliferative syndrome is a rare disease that affects both children and adults. Each of these three words helps describe the main features of this condition. The word autoimmune (self-immune) identifies ALPS as a disease of the immune system. The tools used to fight germs turn against our own cells and cause problems. The word lymphoproliferative describes the unusually large numbers of white blood cells (called lymphocytes (stored in the lymph nodes and spleens of people with ALPS. The word syndrome refers to the many common symptoms shared by ALPS patients. One of the causes of ALPS is defective apoptosis, or said another way, an individual has an abnormality in how well lymphocytes (immune cells) die when they are instructed to do so. It is normal for lymphocytes to disintegrate (e.g., die) when they have done their job. In people with ALPS and in some of their affected relatives, the genetic message for the cells to die is altered: the message is not received and the cells do not die when they should. As a result, people with ALPS develop an enlarged spleen, liver and lymph glands, along with a range of other problems involving white blood cell counts and overactive immune responses (autoimmune disease). Some patients have an increased risk of developing lymphatic cancers (lymphoma). Provided is a description of eligible study candidates: Any patient with ALPS, male or female and of any age. As a patient with ALPS, candidates must have: a medical history of an enlarged spleen and/or enlarged lymph nodes over an extended period of time (past and/or current). defective lymphocyte apoptosis, in vitro. greater than or equal to 1 percent TCR alpha/beta+CD4-8- peripheral blood T cells. Relatives (any age) of patients and normal controls (18-65). Healthy normal volunteers will also be enrolled to provide data on normal cell behavior for comparison with patients. Additional information regarding ALPS and the research being conducted at the National Institutes of Health is available at the following World Wide Web (e.g., Internet) locations: http://www.niaid.nih.gov/publications/alps/ http://www.nhgri.nih.gov/DIR/GMBB/ALPS/. ...

Many genetic diseases of lymphohematopoietic cells (such as sickle cell anemia, thalassemia, Diamond-Blackfan anemia, Combined Immune Deficiency (CID), Wiskott-Aldrich syndrome, chronic granulomatous disease, X-linked lymphoproliferative disease, and metabolic diseases affecting hematopoiesis) are sublethal diseases caused by mutations that adversely affect the development or function of different types of blood cells. Although pathophysiologically diverse, these genetic diseases share a similar clinical course of significant progressive morbidity, overall poor quality of life, and ultimate death from complications of the disease or its palliative treatment. Supportive care for these diseases includes chronic transfusion, iron chelation, and surgery (splenectomy or cholecystectomy) for the hemoglobinopathies; prophylactic antibiotics, intravenous immunoglobulin, and immunomodulator therapies for the immune deficiencies; and enzyme replacement injections and dietary restriction for some of the metabolic diseases. The suboptimal results of such supportive care measures have led to efforts to implement more aggressive therapeutic interventions to cure these lymphohematopoietic diseases. The most logical strategies for cure of these diseases have been either replacement of the patient's own hematopoietic stem cells (HSC) with those derived from a normal donor allogeneic bone marrow transplant (BMT) or hematopoietic stem cell transplant (HSCT), or to genetically modify the patient's own stem cells to replace the defective gene (gene therapy).

Post-transplantation lymphoproliferative disorder (PTLD) develops in one to ten per cent of transplant recipients and can be EBV-associated. To improve long-term efficacy after rituximab monotherapy and to avoid the toxicity of CHOP seen in first-line treatment, the investigators initiated an international multicentre phase II trial to test whether the subsequent application of rituximab and four courses of three-weekly CHOP would improve the outcome of patients with PTLD: PTLD-1, sequential treatment (ST).

The purpose of this study is to determine if treatment with HQK-1004 and valganciclovir will result in complete or partial responses in patients with EBV-positive lymphoid malignancies or lymphoproliferative disorders.

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Monoclonal antibodies, such as rituximab, can block cancer cell growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving bortezomib together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with rituximab works in treating patients with post-transplant lymphoproliferative disorders.

The purpose of this study is to assess whether administration of Arginine Butyrate + ganciclovir/valganciclovir for up to three 21-day cycles is tolerable, and results in partial or complete responses in patients with EBV(+) lymphoid malignancies.
