In previous studies, we have shown that some, but not all low-, intermediate-, and high-purity factor VIII concentrates inhibit interleukin-2 (IL-2) secretion from phytohemagglutinin (PHA)-stimulated T lymphocytes. We now present evidence that this inhibitory action of concentrates is, at least in part, due to contamination with transforming growth factor-beta (TGF-beta). Originally identified ...

There is an ongoing debate whether platelet concentrates (PCs) prepared from either whole-blood donations or by plateletpheresis are superior. Usage of these two product types varies greatly between countries and individual institutions. Some use mainly apheresis PCs; others prefer pooled PCs which are produced from whole-blood donations. This review summarizes the existing information on these...

Background Incidence and mortality from traumatic intra-cranial haemorrhage (ICH) is increased in patients on warfarin [1]. Prothrombin Complex Concentrates (PCC) rapidly reverse warfarin anti-coagulation and have been shown to reduce haematoma expansion and mortality in warfarinised patients sustaining ICH [2]. We aimed to determine the feasibility of pre-hospital use of PCCs by physicians and...
