Technical comparison of four different extracorporeal photopheresis systems.

Extracorporeal photopheresis: Review of technical aspects

Extracorporeal photochemotherapy (ECP) is considered as an immune modulating therapy majorly targeting the T cells of the Immune system. ECP induces an anti-inflammatory condition with tolerogenic responses without inducing a global immunosuppression state which is a typical feature of other therapeutic options such as steroids. Clinical indication of ECP has grown over time since its initial a...

Extracorporeal Photopheresis: Scientific and Technical Considerations for Improving Clinical Management of Patients

Starting at the end of 90’s, and derived from PUVA therapy, arose the concept of modulation of inappropriate immune conflicts by direct action of UVA on immunocompetent cells (lymphocytes, antigen processing cells). After the inactivation of T-cells in vitro and ex vivo, was demonstrated, the development step-by-step aimed to process large amounts of the so-called peripheral mononuclear cells. ...

Extracorporeal Photopheresis as a Treatment of Graft-versus-Host Disease, Autoimmune Disease and Cutaneous T-Cell Lymphoma

[Extracorporeal photopheresis in dermatology].

Extracorporeal photochemotherapy or photopheresis is an immunomodulatory therapy that combines leukapheresis with phototherapy. Blood from the patient is processed to give a leukocyte-rich plasma, which is then treated ex vivo with a photosensitizer and ultraviolet A radiation before reinfusion back into the patient. The exact mechanism of action of photopheresis has not been fully elucidated a...

The Use of Extracorporeal Photopheresis for the Treatment of Acute Graft Versus Host Disease

Acute graft versus host disease (aGVHD) is a key complication of haematopoietic stem-cell transplantation. The main first-line therapy is steroids, however less than half of patients respond to this treatment, and some patients relapse following an initial response. Extracorporeal photopheresis (ECP) is a therapy that has shown promising efficacy in several immune-mediated disorders, including ...
