NCT ID: NCT05191394 Completed - Clinical trials for Therapeutic Plasma Exchange


Start date: September 8, 2021
Phase: N/A
Study type: Interventional

Context: Therapeutic plasma exchange is an extracorporeal blood purification technique that removes pathogenic substances (including antibodies) from plasma. This technique also combines an immunomodulatory effect. The impact on the anti-SARS-CoV-2 titre and the humoral and cellular responses in the general population benefiting from therapeutic plasma exchanges is not known at this time. The purpose of this study is to evaluate the evolution of anti-SARS-CoV-2 antibodies' titre over time in vaccinated adult patients treated with therapeutic plasma exchange. Research question and associated variables: Prospective non-drug interventional study on the possible variation of anti-SARS-CoV-2 antibody titre in adult patients regularly treated with therapeutic plasma exchange. Study population: any adult patient vaccinated against SARS-CoV-2 (any type of vaccine) and regularly receiving therapeutic plasma exchange in the adult hematology department of the Cliniques universitaires Saint Luc in Brussels, Belgium. Number of subjects expected to be enrolled: 10-15

NCT ID: NCT04685655 Terminated - Covid19 Clinical Trials

RescuE pLAsma eXchange in Severe COVID-19

Start date: January 7, 2020
Phase: N/A
Study type: Interventional

The spectrum of coronavirus disease 2019 (COVID-19) ranges from asymptomatic infection to acute respiratory distress syndrome ("ARDS") and patient death. Severely affected patients may develop a cytokine storm-like clinical syndrome with high mortality. Laboratory tests in these patients show an excessive and uncontrolled immune response with consecutive multi-organ failure. In addition, there is evidence for the development of prothrombotic autoantibodies as an epiphenomenon of "Severe Acute Respiratory Syndrome Coronavirus 2" (SARS-CoV-2) infection. Therapeutic plasma exchange ("TPE") is being discussed as a therapeutic alternative in patients with severe, refractory COVID-19. The idea is that plasma exchange eliminates both endogenous and exogenous inducers of an exuberant inflammatory response as well as prothrombotic factors, thus breaking the secondary vicious circle of SARS-CoV-2 infection. In general, TPE is a safe procedure with known efficacy in other severe viral diseases as well as in cytokine storm-like diseases and ARDS of other geneses. Moreover, initial data, mostly derived from case studies, demonstrate promising therapeutic efficacy of TPE in severe COVID-19 courses with previously lacking treatment options. To further evaluate the therapeutic efficacy of TPE in severe COVID-19, a prospective randomized controlled trial of TPE in severe SARS-CoV-2 infection is being conducted at our center. Patients will be randomized to a control group (standard therapy according to center standards) and a therapy/intervention group (standard therapy + TPE).

NCT ID: NCT04351438 Completed - Clinical trials for Anticoagulant Therapy

Evaluation of Complication Rates Using Filter vs. Centrifuge and Heparin vs. Citrate Anticoagulation

Start date: January 1, 2012
Study type: Observational

Despite its growing use across the world, and similar efficacy, filter-based therapeutic plasma exchange (TPE) continues to be used less often that centrifuge-based TPE. One of the reasons is that the patient and circuit complications of centrifuge-based TPE are familiar to the clinical team. There is little data on the patient and circuit complications of filter-based TPE (using the Prismaflex). Furthermore, there is a reluctance to use filter-based TPE because historically, most TPE programs have used citrate-regional anticoagulation, and there is a large gap in knowledge in the use of citrate regional anti-coagulation when using filter-based TPE.
