Development of the S-303 Pathogen Inactivation Technology for Red Blood Cell Concentrates

Development of the S-303 Pathogen Inactivation Technology for Red Blood Cell Concentrates.

Pathogen inactivation systems are in use in many European countries as routine procedures. However, a pathogen inactivation system for erythrocytes is currently not available. Although significant improvements have been made to decrease the incidence of transfusion-transmitted infections, risks remain for infectious disease agents specific to red blood cell concentrates, such as parasitic infec...

Positively Charged Porphyrins: a New Series of Photosensitizers for Pathogen Inactivation in Red Blood Cell Concentrates

Economics of pathogen inactivation technology for platelet concentrates in Japan.

Residual risk of transmitting recognized and emerging blood-borne pathogens via blood transfusion in Japan persists despite advances in blood safety screening. The INTERCEPT Blood System (IBS) for platelets was developed to inactivate a broad spectrum of pathogens to reduce the risk of transfusion-transmitted infections. In this study we assessed the economic impact of the IBS on platelet trans...

Toxicity testing of a novel riboflavin-based technology for pathogen reduction and white blood cell inactivation.

The Mirasol PRT System (Gambro BCT, Lakewood, CO) for platelets and plasma uses riboflavin and UV light to reduce pathogens and inactivate white blood cells in donated blood products. An extensive toxicology program, developed in accordance with International Organisation for Standardisation (ISO) 10993 guidelines, was performed for the Mirasol PRT system. Test and control articles for most of ...

Effect of Irradiation on Microparticles in Red Blood Cell Concentrates

Changes in microparticles (MP) from red blood cell (RBC) concentrates in the context of irradiation have not been investigated. The aim of this study was to evaluate how irradiation affects the number of MPs within transfusion components. Twenty RBC concentrates, within 14 days after donation, were exposed to gamma rays (dose rate: 25 cGy) from a cesium-137 irradiator. Flow cytometry was used t...
