OBJECTIVES: I. Determine the response rate and response duration to rituximab in patients with immune thrombocytopenic purpura.
II. Evaluate the toxicity associated with this treatment regimen in these patients.
III. Evaluate the alteration in antiplatelet antibody with this treatment regimen in these patients.
PROTOCOL OUTLINE: Patients receive rituximab IV on days 1, 8, 15, and 22. Patients who achieve a clinical response lasting over 4 months may receive a second course of rituximab.
Patients are followed at 5, 6, 8, and 12 weeks, and then at 6 and 9 months.
Primary Purpose: Treatment
Purpura, Thrombocytopenic, Idiopathic

This study is designed to investigate the safety of a single infusion of GMA161 in patients with idiopathic thrombocytopenic purpura, as well as, the way the drug enters and leaves the bod...
Idiopathic Thrombocytopenic Purpura (ITP) is classically characterized by a transient or persistent decrease of platelet count. Mortality is higher in the ITP population than the general population, w...
Untreated human immunodeficiency virus (HIV) can be complicated by opportunistic infections, including disseminated histoplasmosis (DH). Although endemic to portions of the United States and usually b...
Patients suffering from congenital thrombotic thrombocytopenic purpura (cTTP) have a deficiency in ADAMTS13 due to mutations in their ADAMTS13 gene.
Ticagrelor, a new type of P2Y12 receptor antagonist, has been highly recommended to be used in acute coronary syndrome by the latest guideline, but its side effects are not well-known. We seek to illu...
Acquired thrombotic thrombocytopenic purpura (aTTP) is an autoimmune disorder characterized by absent ADAMTS13 activity and presence of anti-ADAMTS13 autoantibodies. Recently it was shown that ADAMTS1...
Any form of purpura in which the PLATELET COUNT is decreased. Many forms are thought to be caused by immunological mechanisms.
Thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. It is mediated by immune mechanisms, in most cases IMMUNOGLOBULIN G autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. The disease is seen in acute (affecting children) and chronic (adult) forms.
Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.
A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS). Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.
An ADAMTS protease that contains eight thrombospondin (TS) motifs. It cleaves VON WILLEBRAND FACTOR to control vWF-mediated THROMBOSIS. Mutations in the ADAMTS13 gene have been identified in familial cases of PURPURA, THROMBOTIC THROMBOCYTOPENIC and defects in ADAMTS13 activity are associated with MYOCARDIAL INFARCTION; BRAIN ISCHEMIA; PRE-ECLAMPSIA; and MALARIA.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
