ObjectiveHaemorrhagic shock causes ischaemia and subsequent fluid resuscitation causes reperfusion injury, jointly resulting in high morbidity and mortality. We tested whether the anti-inflammatory fibrin-derived peptide, Bβ15–42, also called FX06, is tissue protective in a model of haemorrhagic shock.MethodsIn a pig model, we standardised the severity of haemorrhagic shock by achieving a cumulative oxygen deficit of approximately 100 ml/kg body weight by withdrawing blood over a period of 1 h. This was followed by resuscitation with shed blood and full electrolyte solution, and pigs were monitored for 3 days. At reperfusion, 17 pigs were randomly assigned to FX06 or solvent treatment.ResultsFX06-treated pigs demonstrated improved cardiac function (stroke volume index: 67 ml/m2 versus 33 ml/m2), decreased troponin T release in the early reperfusion (0.24 ng/ml versus 0.78 ng/ml), decreased AST levels after 24 h (106 U/l versus 189 U/l) and decreased creatinine levels after 24 h (108 μmol/l versus 159 μmol/l). Furthermore, FX06-treated pigs demonstrated preservation of the gut/blood barrier, while controls demonstrated high endotoxin plasma levels indicating translocation of bacteria and/or its products (0.2 EU/ml versus 24.3 EU/ml) after 24 h. This study also demonstrates a significantly improved neurological performance in the FX06 group as determined by S100β serum levels (0.72 μg/l versus 1.25 μg/l) after 48 h and neurological deficit scores (11 versus 70) after 24 h.ConclusionFX06 – when administered as an adjunct to fluid resuscitation therapy – is organ protective in pigs. Further investigations are warranted to reveal the protective mechanism of FX06.
