The use Prometheus FPSA system in the treatment of acute liver failure: preliminary results.

UNLABELLED: The preliminary outcomes of patients with acute liver failure treated with the Prometheus Fractionated Plasma Separation and Absorption (FPSA) system are presented herein. PATIENTS AND METHODS: The procedures were performed in 13 patients (4, intoxication by Amanita phalloides; 4, unknown reason; 3, acetaminophen intoxication; 1, Wilson disease, and 1, liver insufficiency after hemihepatectomy owing to metastases of colon adenocarcinoma). The patients were qualified for the procedure according to the King's College Hospital criteria. The patients' general status was assessed on basic of GCS, UNOS, and the 4-grade encephalopathy classifications. The procedures were performed with the Prometheus 4008H Fresenius Medical Care unit. RESULTS: The 29 procedures were of mean duration 6.5 hours. There were statistically significant reductions in total bilirubin, ammonia, and aminotransferase levels. In addition, the procedures corrected water, mineral, and carbohydrate disorders. One patient did not require liver transplantation. Seven patients received liver transplants: three patients with positive outcomes; two died due to septicemia within 30 days perioperatively, one died at 6 months after OLT owing to respiratory failure; and one, owing to hemorrhagic diathesis. Four patients did not receive a liver transplant because of lack of a organ, no consent for the surgery, or neoplastic disease with metastases. CONCLUSIONS: The Prometheus FPSA-System was an effective detoxication method for patients with acute liver failure. The system was useful as a symptomatic treatment before liver transplantation allowing a longer wait for a graft.

Orthotopic liver transplantation for fulminant hepatic failure.

This paper presents the results of liver transplantation for fulminant hepatic failure in 31 patients qualified as UNOS-1 class (extra-urgent indication for transplantation), operated from January 1989 to April 2005. Twenty-one patients (61.8%) survived the 3-month postoperative period. Three-year survival rate with good liver graft function was 52.9% (18 patients). Before the transplantation, eight patients (23.5%) underwent hepatic dialysis using Fractionated Plasma Separation and Adsorption (FPSA) with the use of a Prometheus 4008H System. Liver transplantation remains the only life-saving procedure for the treatment of fulminant liver failure, regardless of its cause.

The impact of experience of a transplantation center on the outcomes of orthotopic liver transplantation.

The so-called learning factor has been disregarded for many years in analyzing the causes of surgical complications and post-operative mortality; it is also the case for OLT. In our center until April 2003, 209 OLT were performed in 196 patients. We evaluated the impact of experience of the transplantation team on the outcomes of liver transplantation. Thirty-four patients died (mortality rate, 16%) and 1-year survival rate, 64%. Mortality rates varied during different periods of observation due to increasing experience of the transplantation team. The causes of mortality were assessed for a series of 34 patients: it was 75% at the beginning of transplantation procedures while recent deaths have not recently exceeded 10% of cases.
