Medical and Biotech [MESH] Definitions
Any form of purpura in which the PLATELET COUNT is decreased. Many forms are thought to be caused by immunological mechanisms.
Purpura, Thrombocytopenic, Idiopathic
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.
Purpura, Thrombotic Thrombocytopenic
An acquired, congenital, or familial disorder caused by PLATELET AGGREGATION with THROMBOSIS in terminal arterioles and capillaries. Clinical features include THROMBOCYTOPENIA; HEMOLYTIC ANEMIA; AZOTEMIA; FEVER; and thrombotic microangiopathy. The classical form also includes neurological symptoms and end-organ damage, such as RENAL FAILURE.
The purpose of this study is to further evaluate the effects that eltrombopag has on platelets in subjects with chronic ITP. Eltrombopag is approved by the Food and Drug Administration (FD...
An open-label, dose-adjustment, extension study to evaluate the safety and efficacy of eltrombopag for the treatment of subjects with idiopathic thrombocytopenic purpura (ITP) who have pre...
This is a single-center, prospective, controlled study with one eltrombopag treatment group and 2 control groups, one on standard steroid treatment, and another one untreated. The aim of...
The rationale for this Phase III study is to evaluate the 6 month safety and efficacy of eltrombopag in the treatment of previously treated subjects with chronic ITP. The starting dose of...
The purpose of this study is to determine the safety and efficacy of AKR-501 administered in patients with chronic Idiopathic Thrombocytopenic Purpura (ITP) who were enrolled into and comp...
The population pharmacokinetics of eltrombopag were characterized in healthy subjects (n = 111) and patients with idiopathic thrombocytopenic purpura (ITP) (n = 88) using nonlinear mixed-effects model...
Fifty-four adult German patients suffering from idiopathic thrombotic thrombocytopenic purpura (TTP) have been examined for HLA class II. All patients presented autoantibodies against ADAMTS13 and ADA...
Thrombelastography (TEG) analyses the status of blood coagulation including abnormalities associated with low platelet count. The aim of this study was to investigate the changes in TEG parameters in...
Eltrombopag, an orally-active small molecule thrombopoietin (TPO) receptor agonist, was used for the first time in 2008 to treat patients with chronic idiopathic thrombocytopenic purpura. Here, we inv...
