Active clinical trials for "Thrombocytopenia"

Primary immune thrombocytopenia (ITP) is an acquired autoimmune bleeding disorder, accounting for about 1/3 of clinical hemorrhagic diseases. Loss of immune tolerance leading to increased platelet destruction and decreased platelet production is the main pathogenesis of ITP. Dysbiosis of the gut microbiota was found in many autoimmune diseases like rheumatic arthritis(RA),inflammatory bowel disease(IBD),multiple sclerosis and probiotic treatment or fecal microbiota transplantation(FMT) which can regulate the gut microbiota has good clinical efficacy in those disorders. One ITP patient with ulcerative colitis(UC) was treated with FMT and got progressive but significant increase in platelet level and lasted for several years.

Single-arm, open-lable, multicentre study to compare the efficacy and safety of atorvastatin, acetylcysteine plus danazol with danazol monotherapy in patients with corticosteroidresistant/relapsed ITP.

Heparin-induced thrombocytopenia (HIT), a condition characterized by low platelet levels and possible blood clots, occurs in a small number of people after treatment with the drug heparin. Some people with HIT may show symptoms of a blood clot at the time of HIT diagnosis, but in another form of HIT, known as isolated HIT, people do not show blood clot symptoms even though they might have a blood clot. This study will use ultrasound tests to evaluate the presence of blood clots at the time of an HIT diagnosis and in the following month.

RATIONALE: Studying samples of blood in the laboratory from patients receiving temozolomide may help doctors learn how temozolomide works in the body. It may also help doctors learn more about how a patient's genes may affect the risk of developing thrombocytopenia. PURPOSE: This clinical trial is studying the pharmacokinetics in patients with newly diagnosed high-grade glioma receiving temozolomide and radiation therapy.

Immune Thrombocytopenia (ITP) is a disorder resulting in impaired platelet production and enhanced destruction on the basis of autoantibody-mediated mechanisms. Patients with ITP are at increased risk of bleeding and infection. First line therapy includes glucocorticoids, with or without the addition of intravenous immune globulin (IVIg) when a prompt platelet response is desired. The likelihood of stable and safe disease after first-line treatment ranges from 30-60% and risk of relapse requiring additional therapy occurs in 50-80% of patients. Moreover, the toxicity associated with first and subsequent therapy for ITP is substantial. Oseltamivir is an attractive drug for ITP since it specifically targets a pathophysiologic mechanism that appears to be important for the development of ITP and has a benign side effect profile compared to standard ITP therapy. Oseltamivir has never been rigorously tested in humans to determine its efficacy in the management of ITP. The investigators therefore propose the first randomized, double blind study to assess the impact of oseltamivir on biological markers in adult patients with ITP. This study will also provide information about the feasibility of recruitment into a definitive trial, which would be coordinated by St. Michael's Hospital. The research question is: Do adults (≥ 18 years) with ITP treated with oseltamivir at 75mg twice daily for 5 consecutive days have an increase in their mean platelet glycoprotein sialylation compared to those receiving placebo? This pilot, proof-of-concept, randomized controlled clinical trial will enroll 30 individuals with ITP. Randomization and allocation will occur at a ratio of 1:1. Analysis of the primary outcome measure will occur via analysis of covariance (ANCOVA). This study has the potential to dramatically change the treatment of ITP. If the results from this study demonstrate a biological effect, and results from the subsequent definitive study are positive, The investigators envision a move away from non-specific immune-blunting therapy such as prednisone, towards tailored therapy with oseltamivir. It could diminish the lifelong summative immunosuppressive therapy burden, associated drug toxicity and improve long- and short-term health outcomes for these patients.

Nowdays HDACi's were more and more focused on the anti-inflammatory and immunomodulatory activities,independent of their known proapoptotic or cell cycle arrest actions on malignant cells. Low concentrations of HDACi's are effective in reducing inflammation and autoimmune response in humans with juvenile idiopathic arthritis and animal models of inflammatory bowel disease and arthritis. The project was undertaking by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of the low dose chidamide in the management of refractory ITP.

Randomized, open-label, multicentre study to assess the efficacy and safety of the combination of low-dose rituximab and ATRA in patients with steroid-resistant/relapsed ITP.

Single-arm, open-label, single center study to assess the efficacy and safety of terbutaline plus danazol in patients with corticosteroid resistant/relapsed ITP.

This multicenter randomized, open-label study aimed to compare the efficacy and safety of eltrombopag combining rituximab with eltrombopag in China adult ITP patients .This study was be conducted in adult ITP patients who had not responded to or had relapsed after previous treatment of ITP, including first line therapy and /or splenectomy.

This is a prospective, single-arm study to investigate the efficacy and safety of the combination of fixed low-dose eltrombopag plus recombinant human thrombopoietin (rhTPO) as treatment for corticosteroid-resistant or relapsed immune thrombocytopenia (ITP) patients during the COVID-19 pandemic.
