Differential modulation of endothelial cell function by fresh frozen plasma

Fresh frozen plasma induced thrombocytopenia

Transfusions of blood products are common in medical practice and can be lifesaving in certain situations. Potentially life threatening reactions could occur and physicians should be alerted. Here we describe a case of thrombocytopenia that was induced by transfusion of fresh frozen plasma (FFP). A 52 years old male presented to the emergency department after two episodes of hematochezia that r...

Avoiding the misuse of fresh frozen plasma.

Prevention of intraventricular haemorrhage by fresh frozen plasma.

Seventy three preterm infants weighing less than 1500 g or less than 32 weeks' gestation, or both, were allocated randomly to treatment (fresh frozen plasma 10 ml/kg on admission and at 24 hours of age) or control groups. Fifteen (41%) out of 37 control patients sustained intraventricular haemorrhage compared with five (14%) of 36 patients receiving treatment (X2 = 5.24, P = 0.022). No differen...

Assessment of Vascular Endothelial Growth Factor in Fresh versus Frozen Platelet Rich Plasma

Platelet rich plasma (PRP) is hemoconcentration with platelets concentration above baseline values and high concentration of many growth factors. The aim of this study was to assess freezing effect on vascular endothelial growth factor (VEGF) release from PRP using two different activation methods to simplify its use in different clinical applications. PRP was prepared using two-centrifugation ...

Paracrine modulation of heart cell function by endothelial cells.

An accumulating body of experimental data supports the presence of a paracrine pathway for the modulation of myocardial function by cardiac endothelial cells. Cardioactive substances released by endothelial cells include nitric oxide, endothelin-1, prostanoids, adenylpurines, natriuretic peptides, and other agents that have so far only been characterised in bioassay studies. Endothelial cells a...
