[Liver failure as part of multiple organ failure following polytrauma]

In the last few years there has been increasing evidence that adult respiratory distress syndrome is only part of a much more complex syndrome called multiorgan failure (MOF). Since renal and lung failure have become rare because of our increased understanding of the pathomechanisms involved and the treatment changes, liver dysfunction has been noted more often. In a clinical trial with 38 patients with severe trauma, we investigated liver function using ordinary parameters like the transaminases, bilirubin, etc. To define one group with MOF and one without we used the Goris MOF Score. In both groups glutamate dehydrogenase (GLDH) was increased initially up to 14 U/l, indicating hypoxia of the liver cells right after trauma. From day 6 on, a second increase up to 12 U/l of GLDH in the MOF group was evidence of liver cell dysfunction. The glutamine oxalacetic transaminase (GOT) level remained normal in both groups after an initial increase of up to 60 U/l in both groups. As 30% of serum GOT is released by muscle cells, the initial peak values could be due to direct muscle trauma, because an initial increase was noted even in the creatinine kinase. A decrease in clotting factor V down to 30% on day 8 in the MOF group indicated that the metabolic synthesis activity of the liver was lower. Bilirubin increased in the MOF group from day 5 on up to 240 mumol/l on the day 14. As this increase was not parallel to the gamma glutamyl transferase (Gamma BT) level, the reason for the bilirubin increase may be dysfunction of the liver cell membrane.(ABSTRACT TRUNCATED AT 250 WORDS)
