iNO therapy and human liver transplantation.

(A) Experimental protocol for administering placebo or iNO to patients and sample (blood and liver biopsy) collection. (B) Methemoglobin (metHb) levels as a function of blood draw. ^#P ≤ 0.001 for corresponding placebo versus iNO measurements by unpaired t test. (C) Volume of platelets transfused during surgery ^#P ≤ 0.05. (D and E) Average percent decrease in PT and PTT after surgery. Data are normalized to coagulation times measured immediately (<1 hour) after surgery and were 26.7 ± 1.4 seconds (placebo) and 34.4 ± 2.5 seconds (iNO) for PT and 54.6 ± 7.3 seconds (placebo) and 70.2 ± 6.5 seconds (iNO) for PTT. (F and G) Average percent decrease in serum ALT and AST levels after surgery. Data were normalized to ALT and AST levels measured immediately (<1 hour) after surgery and were 601.8 ± 145.4 U/l (placebo) and 689.3 ± 149.5 U/l (iNO) for ALT and 922.1 ± 228.7 U/l (placebo) and 940.9 ± 211.3 U/l (iNO) for AST. For data in panels D–G, *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001 for corresponding placebo versus iNO measurements. (H) Cox analysis of patient hospital length of stay. P = 0.034 adjusted for sex and cold ischemic time. Filled squares: placebo; filled circles: iNO.
