Filter by:Henoch Schonlein Purpura (HSP), vasculitis of small vessels with deposits of IgA, is considered by many authors as the systemic form of Berger's disease (IgA-N). IgA-N is characterized by IgA1 deposits in mesangial areas associated with mesangial proliferation. These two diseases remain the leading cause of ESRD by primitive glomerulopathy in Western countries. In recent years, considerable progress has been made in understanding the pathophysiological mechanisms of IgA-N. However, only a high rate of proteinuria at one year or the presence of severe glomerular inflammation on renal biopsy remain predictors of long term renal function. Moreover, the high variability of HSP clinical expression, from few purpura skin lesions that evolve favourably spontaneously, to rapidly progressive renal failure, remains so far unexplained but suggests the existence of individual genetic susceptibility. In the first part of the study, we will study key factors based on physiopathological data obtained by our laboratory as well as by other groups. The second part of the study concerns genetic factors. Although the candidate genes that may confer a particular susceptibility to the disease, to progress to ESRD or respond to treatment are many, the genes involved in inflammation or controlling renin-angiotensin system are of particular interest. We will apply these results by studying patients with HSP showing three distinct phenotypes (HSP with isolated cutaneous purpura or associated with minimal or severe renal disease) at diagnosis and after clinical remission. The purpose of this study is to assess whether the phenotype at diagnosis is associated with the physiological markers and if one of them predicts a pejorative evolution of renal disease at 1 year. Meanwhile, study of polymorphism of selected genes of interest could allow identification of patients with specific genetic susceptibility or with bad prognosis factors who would be thus eligible for specific treatment.
With conventional treatments (i.e. iv Ig, steroids) the overall response rate of ITP secondary to LPD is generally lower than in primary ITP, and usually not higher than 50% (95% CI 27-72). Eltrombopag which has proved very effective in primary ITP could be effective also in ITP secondary to LPDs. This novel ITP specific treatment might spare these patients not only from bleeding risk but also from toxic or inappropriate cytotoxic therapies, not otherwise demanded by the burden of the underlying disease.
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).
The investigators are trying to investigate the coagulation status of idiopathic (immune) thrombocytopenic purpura patients by measuring the platelet count, coagulation battery, von Willebrand factor level, thromboelastography.
Thrombotic thrombocytopenic purpura (TTP) is a disease characterized by small blood clots throughout the body that can damage major organs and cause death. TTP is treated with plasma exchange (also called "plasmapheresis"). Patients who do not respond initially to plasma exchange often are helped by later treatment with rituximab. The purpose of this study is to see whether combining low doses of rituximab with plasma exchange will help patients get better sooner and reduce the chance of getting TTP again.
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 refractory immune thrombocytopenia (ITP), compared to conventional Rituximab therapy.
The purpose of this study is to investigate the efficacy, safety and tolerability of eltrombopag in children with previously treated chronic immune thrombocytopenia who are between 1 and 17 years of age. This is a 2 part study. In part 1, patients will be randomized to receive either eltrombopag or placebo for 13 weeks. All patients who complete part 1 will enter part 2. In part 2, all patients will receive 24 weeks of eltrombopag.
Symptoms of Primary Immune Thrombocytopenic Purpura (pITP), such as spontaneous bruising, menorrhagia, mucosal bleeding and other symptoms might significantly affect the HRQOL of pITP patients. However, very little evidence exists on HRQOL outcomes in patients diagnosed with pITP. The investigators project will aim at providing scientific community solid evidence based data on the extent to which HRQOL is compromised and in which specific area. The purpose of this study is thus to compare generic Health-related Quality of Life (HRQOL) profiles of adult patients with primary Immune Thrombocytopenic Purpura (pITP) with that of a matched Italian population control Group.
The purpose of this study is to determine whether Recombinant Human Thrombopoietin (rh-TPO) in combination with Rituximab are effective and safe in the management of Steroid-Resistant/Relapsed Immune Thrombocytopenia (ITP).
This is an open label 6 month pilot study for male and female participants over the age of 52 that desire treatment and prevention of senile purpura of the forearms. This study will be evaluating the effects of Adapalene 0.3% for the use in the treatment and prevention of senile purpura.
