After IRB approval blood samples were taken in 10 patients age 20-51 years with ALF. Blood was taken before OLT (A), during the anhepatic phase (B), 30 min after reperfusion (C), and on days 1 (D) and 4 (E) post-OLT. The blood was centrifuged and serum stored at -70°C. S100 was analysed using an immunoluminometric assay.
Serum S100 is elevated in ALF and encephalopathy. We observed a rise in S100 during OLT in these patients. The role of S100 as a marker of neuronal injury in ALF and OLT warrants further investigation.
