A randomized trial of solvent/detergent and standard fresh frozen plasma in the treatment of the coagulopathy seen during Orthotopic Liver Transplantation.

BACKGROUND: Viral transmission remains a residual risk in single unit blood component therapy. Virus inactivation of pooled fresh frozen plasma (FFP) by the solvent/detergent (SD) method can be used to reduce this risk but results in some loss of factor activity including factor VIII and (2-antiplasmin. This study was aimed at assessing the clinical effectiveness solvent/detergent treated pooled fresh frozen plasma (SDFFP) in the correction of the coagulopathy seen during Orthotopic Liver Transplantation (OLT) as compared with standard FFP.

METHOD: Twenty eight patients with an underlying derangement of coagulation and who were due to undergo OLT were randomized to receive either FFP or SDFFP. They were assessed for side effects, correction of coagulopathy, and seroconversion for viral markers.

RESULTS: Patients undergoing OLT showed equal correction of clotting factors and partial thromboplastin time (PTT) when treated with FFP or SDFFP. There was also a similar time course to return to baseline values in each group. There was no significant difference in correction of INR in either group. Usage of other blood components during the operation was identical in the two groups. No seroconversions were seen for HIV, HBC or HCV but only 12 patients were available for long term follow-up.

CONCLUSION: SDFFP is an efficacious and safe source of coagulation factors for patients with liver disease undergoing Orthotopic Liver Transplantation. No adverse effects were seen during its administration. Further work is required to ascertain long term possibilities of seroconversion.
