Comparative Study
Association between donor-recipient serum sodium differences and orthotopic liver transplant graft function.
Previous studies have shown that donor hypernatremia and possibly recipient hyponatremia negatively impact graft function after orthotopic liver transplant (OLT). The purpose of this retrospective investigation was to determine whether measured differences in serum sodium values between cadaveric donors and OLT recipients (DeltaNa(+)) influence immediate postoperative allograft function and short-term patient outcomes. Two hundred and fifty patients that underwent OLT from January 2001 to December 2005 were included in this study. ⋯ However, both the preoperative MELD score and HTK preservation solution used were significantly associated with several patient outcomes. A higher MELD score was associated with both increased red blood cell (RBC) (P < 0.001) and fresh frozen plasma (FFP) usage (P = 0.002), elevated postoperative total bilirubin levels (P < 0.001), increased LOHS (P = 0.04), and a higher 30-day post transplant mortality (P = 0.02). The use of HTK preservation solution was associated with higher mean postoperative aspartate aminotransferase levels (P = 0.02) and decreased mean RBC (P < 0.001) and FFP usage (P = 0.009) compared to UW preservation solution use.

Comparative Study
Safety and efficacy of N-acetylcysteine in children with non-acetaminophen-induced acute liver failure.
Acute liver failure (ALF) carries a high mortality in children. N-acetylcysteine (NAC), an antioxidant agent that replenishes mitochondrial and cytosolic glutathione stores, has been used in the treatment of late acetaminophen-induced ALF and non-acetaminophen-induced ALF. In our unit, NAC was introduced as additional treatment for non-acetaminophen-induced ALF in 1995. ⋯ Death after transplantation occurred in 15 (39%) in Group 1 vs. 8 (16%) in Group 2, P = 0.02. In conclusion, NAC is safe in non-acetaminophen-induced ALF. In this retrospective study NAC was associated with a shorter length of hospital stay, higher incidence of native liver recovery without transplantation, and better survival after transplantation.
