Filter by:The purpose of this study is to determine the efficacy of H. pylori eradication for the treatment of chronic or persistent immune thrombocytopenic purpura (ITP) patients with moderate thrombocytopenia. This is a multi-center, open label, prospective randomized phase IIl study.
Thrombocytopenia refers to a reduction in platelet count to (<150 × 109/L). Immune thrombocytopenic purpura is an acquired autoimmune disorder defined by isolated thrombocytopenia and the exclusion of other causes of thrombocytopenia
Assessment of quality of life of patient with chronic idiopathic thrombocytopenic purpura according to the type of treatment
This study is a two phase study that aims to evaluate if low-dose Rituximab maintenance therapy may prolong the the effect of Rituximab in immune thrombocytopenia.
The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.
Multi-center sequential multiple assignment randomized trial comparing the effectiveness of three different standard of care treatment options for patients with isolated skin vasculitis.
In this prospective, randomized, controlled clinical trial investigators' aim was to compare the efficacy and the adverse effect of 3 therapy cycles of HD-DXM versus conventional treatment with PDN for untreated adult patients with ITP. In this study standardized criteria and definitions were used according to consensus international working group guideline for ITPto compare clinical outcomes of the two corticosteroid treatment regimens and determine the superior regimen as a first line strategy for new primary ITP in adults
The chronic immune thrombopenia is an autoimmune disease caused by B cells. These cells produce anti platelets and megakaryocytes antibodies. Some B cells, named regulatory B cells, are known to control other cells. Their action in chronic immune thrombopenia is actually unknown.
The objectives of this study were to evaluate long-term safety and efficacy of caplacizumab, to evaluate safety and efficacy of repeated use of caplacizumab and to characterize long-term impact of acquired thrombotic thrombocytopenic purpura (aTTP).
Henoch-Schonlein purpura nephritis(HSPN) is one of the most common secondary glomerulonephritis in children. A large, prospective, multicenter cohort study is being conducted in three institutions. Eligible Henoch-Schönlein purpura nephritis children will be classified as the experimental group (n=300) and the control group (n=300) based on the interventions they receive. Patients taking Chinese herbal formula will be in the experimental group, and those taking Western medicine will be in the control group. The entire study will last 60 weeks, including a 12-week observation period and a followup at 12 months.
