Brief Summary:
Randomized prospective study on the impact on the post-LT outcome by the infusion of N-acetylcysteine (NAC) during the liver procurement procedure, as an anti-oxidant agent to reduce the ischemia-reperfusion damage of organs for liver transplantation (LT).

Liver Failure Liver Failure, Acute Liver Diseases Carcinoma, Hepatocellular Liver Neoplasms Drug: N-acetylcystein Phase 2

Detailed Description:

Anti-oxidant agents have the potential to reduce the ischemia-reperfusion damage of organs for liver transplantation (LT). In this randomized prospective study, we seek to study the impact on the post-LT outcome of the infusion of N-acetylcysteine (NAC) during the liver procurement procedure.

Potential grafts, assigned to adult candidates with chronic liver disease enlisted for first LT, will randomly be included in a one‑to‑one ratio with a sequential closed envelope single-blinded assignation procedure to either the NAC protocol or in the standard procedure (without NAC).

The NAC protocol comprises: a systemic NAC infusion (30 mg/kg) one hour before the beginning of liver procurement; a loco-regional NAC infusion (300 mg through the portal vein) just before cross‑clamping.

Official Title: Infusione Sistemica e Loco-regionale di N-Acetilcisteina Nel Prelievo di Fegato: Uno Studio Prospettico Randomizzato Controllato. Fase II.
Study Start Date : December 2006
Actual Primary Completion Date : July 2009
Actual Study Completion Date : July 2009

Arm Intervention/treatment
Experimental: NAC procurement protocol
The allocated organ, in addition to the standard procedure, was treated with a systemic NAC infusion before initiating the liver harvesting procedure, and a loco‑regional infusion into the portal vein before cross‑clamping.
Drug: N-acetylcystein
15 min systemic NAC infusion of the donor (30 mg/kg, maximum dose 3000 mg) diluted into 500 ml 5 % glucose solution, 30 min before initiating the liver harvesting procedure, and a loco‑regional infusion (150 mg/kg of estimated liver weight, maximum dose 300 mg) into the portal vein 5 min before cross‑clamping.

No Intervention: Standard procurement procedure
Allocated organ was treated according to the centre's standard procurement procedure: a modified double perfusion technique, where donor livers are gravity-perfused in situ via the aorta and portal vein with Celsior solution at 4 °C. After hepatectomy, donor livers were further perfused at the back‑table with Celsior solution and then stored in conventional bags containing the same solution at 4 °C until transplantation.

Primary Outcome Measures :
  1. Graft survival [ Time Frame: up to 60 months ]

Secondary Outcome Measures :
  1. Patient survival [ Time Frame: up to 60 months ]
  2. Primary graft dysfunction [ Time Frame: up to 60 months ]
