摘要

Background Emerging viruses like severe acute respiratory syndrome coronavirus (SARS-CoV), Crimean-Congo haemorrhagic fever virus (CCHFV) and Nipah virus (NiV) have been identified to pose a potential threat to transfusion safety. In this study, the ability of the THERAFLEX UV-Platelets and THERAFLEX MB-Plasma pathogen inactivation systems to inactivate these viruses in platelet concentrates and plasma, respectively, was investigated. Materials and methods Blood products were spiked with SARS-CoV, CCHFV or NiV, and then treated with increasing doses of UVC light (THERAFLEX UV-Platelets) or with methylene blue (MB) plus increasing doses of visible light (MB/light; THERAFLEX MB-Plasma). Samples were taken before and after treatment with each illumination dose and tested for residual infectivity. Results Treatment with half to three-fourths of the full UVC dose (0 center dot 2 J/cm(2)) reduced the infectivity of SARS-CoV (>= 3 center dot 4 log), CCHFV (>= 2 center dot 2 log) and NiV (>= 4 center dot 3 log) to the limit of detection (LOD) in platelet concentrates, and treatment with MB and a fourth of the full light dose (120 J/cm(2)) decreased that of SARS-CoV (>= 3 center dot 1 log), CCHFV (>= 3 center dot 2 log) and NiV (>= 2 center dot 7 log) to the LOD in plasma. Conclusion Our study demonstrates that both THERAFLEX UV-Platelets (UVC) and THERAFLEX MB-Plasma (MB/light) effectively reduce the infectivity of SARS-CoV, CCHFV and NiV in platelet concentrates and plasma, respectively.
