Abstract

Ischemia/reperfusion (IR) injury in transplanted livers contributes to organ dysfunction and failure and is characterized in part by loss of NO bioavailability. Inhalation of NO is nontoxic and at high concentrations (80 ppm) inhibits IR injury in extrapulmonary tissues. In this prospective, blinded, placebo-controlled study, we evaluated the hypothesis that administration of inhaled NO (iNO; 80 ppm) to patients undergoing orthotopic liver transplantation inhibits hepatic IR injury, resulting in improved liver function. Patients were randomized to receive either placebo or iNO (n = 10 per group) during the operative period only. When results were adjusted for cold ischemia time and sex, iNO significantly decreased hospital length of stay, and evaluation of serum transaminases (alanine transaminase, aspartate aminotransferase) and coagulation times (prothrombin time, partial thromboplastin time) indicated that iNO improved the rate at which liver function was restored after transplantation. iNO did not significantly affect changes in inflammatory markers in liver tissue 1 hour after reperfusion but significantly lowered hepatocyte apoptosis. Evaluation of circulating NO metabolites indicated that the most likely candidate transducer of extrapulmonary effects of iNO was nitrite. In summary, this study supports the clinical use of iNO as an extrapulmonary therapeutic to improve organ function following transplantation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Nitric oxide inhalation is used in infants with primary pulmonary hypertension of the newborn to reduce pulmonary artery pressure.

    “It is used in infants with primary pulmonary hypertension of the newborn to reduce pulmonary artery pressure.158”

    From Nitrate-Nitrite-Nitric Oxide Pathway: Implications for Anesthesiology and Intensive Care (2010) · cites this paper as [158]

    The Introduction says inhaled NO has been used clinically to reduce pulmonary artery pressures, but describes patients with inflammatory-mediated lung injury. It does not specify infants or primary pulmonary hypertension of the newborn; the study itself enrolled adults undergoing liver transplantation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Inhaled NO therapy before liver transplantation significantly elevates tissue nitrite levels that are associated with cytoprotection.

    “A previous study from Lang et al demonstrated that inhaled NO therapy before liver transplanation significantly elevated tissue nitrite levels that were associated with cytoprotection [166].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
