Active clinical trials for "Purpura"

The project was undertaking by Qilu Hospital of Shandong University and other 13 well-known hospitals in China. In order to report the efficacy and safety of Recombinant Human thrombopoietin combining with Rituximab for the treatment of adults with primary immune thrombocytopenia (ITP), compared to conventional high-dose dexamethasone therapy.

Thrombotic thrombocytopenia purpura / hemolytic uremic syndrome (TTP/HUS) is a rare, life-threatening disorder. TTP/HUS causes multiple blood clots to form, which prevents blood from reaching the brain and kidneys. TTP/HUS affects 3-5 people per million per year. Anyone can develop TTP/HUS, but it is most common among 30-40 year olds, and women are twice as likely as men to acquire the condition. TTP/HUS sometimes develops as a result of medication use, pregnancy or cancer; however, for the majority of patients (80%) the cause of TTP/HUS is unknown. In 1991, researchers discovered that plasma exchange was superior to plasma infusion in treating idiopathic TTP/HUS. During plasma exchange the patient's blood plasma is removed and replaced with healthy blood plasma. Without plasma exchange, the survival rate for TTP/HUS is extremely low, with fewer than 5% of patients surviving. Treating TTP/HUS with plasma exchange improved the survival rate to 80%. Although this represents a dramatic improvement, researchers are still searching for methods to improve survival. No major advances in treating TTP/HUS have occurred in the past 20 years. Recent research suggests that high-dose plasma exchange may improve the survival of TTP/HUS patients. The investigators will conduct a randomized controlled trial to test whether treating TTP/HUS patients with high-dose versus standard-dose plasma exchange improves the treatment response. The investigators will recruit 150 patients with TTP/HUS from 9 centres across Canada over three years. The investigators will evaluate whether high-dose plasma exchange improves the treatment response, survival, and whether it reduces the number and volume of plasma exchange procedures and duration of hospital stay.

The objectives of this study are to evaluate the safety and efficacy of 0.5% retinol (Vitamin A) versus it's vehicle cream in the treatment and prevention of skin aging and Bateman's Purpura (bruising).

The project was undertaking by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of All-Trans Retinoic Acid (ATRA) combining with High-dose Dexamethasone for the treatment of adults with primary immune thrombocytopenia (ITP), compared to conventional high-dose dexamethasone therapy.

The purpose of this study is to evaluate efficacy, safety and tolerability of blisibimod when administered on top of standard-of-care to subjects with Immune Thrombocytopenic Purpura (ITP).

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 study is to determine the effect of Thrombopoietin Receptor (MPL) agonists on shear-induced platelet activation.

The purpose is to evaluate safety and feasibility of the use of Rituximab as an adjunct to standard therapy (plasmapheresis + steroids) for patients with thrombotic thrombocytopenic purpura (TTP). This includes evaluating the rate and type of treatment failure.

The purpose of this study is to assess the feasibility of a randomized, double blind, placebo controlled trial of add-on rituximab for non-splenectomized adults with acute immune thrombocytopenic purpura (ITP).

The purpose of this research study is to compare the efficacy and safety of higher doses of rituximab to a combination of standard doses of Rituxan + CVP (Cyclophosphamide, Vincristine, and Prednisone) in patients with chronic Idiopathic Thrombocytopenic Purpura (ITP who did not respond to or relapsed after standard doses of rituximab.

The main objective of this study is to describe the management of children with rheumatoid purpura from admission to the pediatric emergency room to follow-up by primary care physicians after hospital discharge.
