Filter by:The investigators would like to analyze platelet/leukoplak activation, quantify and morphologically characterize these aggregates using in vitro analysis, directly on whole blood from adult patients with suspected HIT. This would enable to better describe the in vivo pathophysiology of the HIT-suspect patient, and eliminate the need for platelet donors to perform the usual confirmatory techniques, whose inter- and intra-individual variability is very high. What's more, the SRA test, evaluated as the reference test, requires the use of radioisotopes and is therefore only carried out in a few biological expertise centers, resulting in a very long delay in the delivery of results. It should also be noted that, in practice, HÉPARINE is immediately stopped in patients with suspected HIT, and they are put on an expensive anticoagulant (DANAPAROIDE SODIQUE or ARGATROBAN) in curative doses until the results of the confirmatory tests are back. In this serious, life-threatening condition, it is essential to have a sensitive, specific test to confirm HIT as quickly as possible. Each patient with suspected HIT (rapid >30% reduction in platelet count after initiation of heparin therapy) should have 4 tubes of 3.2% citrated whole blood (2.7ml) collected at the time of suspected HIT (D0) and before any therapeutic switch (or 24 h max after switch). A new sample (4 citrated tubes) will be taken at D4, D7 and D14 during hospitalization, in patients who test positive for anti-PF4/H Ac. All patients with suspected HIT will follow the standard diagnostic pathway, i.e. a screening test (immunological test for anti-PF4/heparin antibodies, total Ig, ACL TOP, Werfen) followed by a confirmatory test (platelet aggregation on TA-8V, STAGO and/or SRA). Doppler ultrasonography of the lower limbs will be performed in HIT-suspect patients with a positive anti-PF4/H antibody test, as currently performed as part of routine care.
A single-center, open-label, off-label use investigator-initiated clinical study with safety run-in to explore the clinical activity and safety of Anti-CD38 Antibody in adult ES patients who have not responded adequately or relapsed after first-line treatment and at least one second-line therapy including immunosuppressive agents, Anti-CD20 Antibody and/or TPO-RA, or those in whom no other second-line treatment options are suitable.
This is a multi-center, retrospective clinical study to analyze the clinical features, laboratory indicators, imaging changes, treatment options and long-term prognosis in patients with sever fever with thrombocytopenia syndrome. All hospitalized patients with sever fever with thrombocytopenia diagnosed between 2016 and 2022 were included from the electronic medical record system of 8 centers, and demographics, hospitalization information, clinical information, laboratory or imaging examinations, treatment options, and outcomes were collected.
A Randomized, Double-blind, Placebo-controlled Phase III Clinical Study to Evaluate the Efficacy and Safety of Orelabrutinib in Adult Patients with Chronic Primary Immune Thrombocytopenia
This study is conducted to evaluate the efficacy of avatrombopag for thrombocytopenia in patients with hepatocellular carcinoma (HCC) who intend to undergo transarterial chemoembolization (TACE) and/or hepatic arterial infusion chemotherapy (HAIC).
To evaluate the safety and efficacy of Obinutuzumab in the treatment of immune thrombocytopenia in patients who have not responded adequately or relapsed after first-line treatment.
To evaluate the safety and efficacy of anti-CD38 antibody in the treatment of antiphospholipid syndrome with secondary thrombocytopenia in patients who have not responded adequately or relapsed after first-line treatment and at least one second-line therapy including rituximab and/or TPO-RA.
- Study the effect of acetylcysteine on decreasing the incidence of LIT in critically ill patients. - Study the impact of acetylcysteine on the time to onset of LIT and the time to recovery of platelets.
- To identify the incidence of LIT among critically ill patients, as limited studies have only addressed this population. - To evaluate the impact of several factors on the incidence of LIT, the time to onset of LIT, and the time to recovery of platelets. - To study the effect of concurrent medications (enoxaparin, unfractinated heparin, piperacillin, carbapenems, tigecycline, fluconazole or voriconazole, digoxin, amiodarone, acetaminophen, tirofiban, statins, and antiepileptics) frequently used in critically ill patients on the incidence of LIT. - To investigate the impact of possible medications with an antioxidant effect on the prevention of LIT. - To assess the impact of LIT on composite end point (mortality, bleeding, and length of stay)
The project was undertaking by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of Hetrombopag plus high-dose dexamethasone for the treatment of adults with newly-diagnosed primary immune thrombocytopenia (ITP).
