Abstract

Background.

Recently, the model of end-stage liver disease (MELD) index has been used to select patients with acute liver failure (ALF) for transplantation. By the time the indication for orthotopic liver transplantation (OLT) is defined, the patient's clinical status may worsen.

Objective.

In this study, MELD was used to define patients beyond OLT.

Methods.

Among adult patients ALF was responsible for 17 OLT. Their medical records were reviewed to calculate the MELD score just before the OLT. MELD of the deceased patients after OLT (group 1, n = 8), was compared with the MELD score of living recipients (group 2, n = 9). Creatinine level, need for dialysis, use of vasoactive amines, and mechanical ventilation before OLT were also analyzed in these groups. A significant difference was defined whenP<.05.

Results.

The mean MELD score ± SD was 51.86 ± 12.3 for group 1, and 38.47 ± 7.1 for group 2 (P= .02). There was no difference between the creatinine values for patients in the 2 groups (P= .20). Also, the use of vasoactive amines or the need of dialysis before OLT were not different (P= .12 andP= .25, respectively). Group 1 was more frequently under mechanical ventilation, and showed a 4.29 relative risk for death after OLT.

Conclusion.

MELD score could be useful to define the prognosis of OLT among patients with ALF.
