Abstract

Patients with liver disease have increased plasma concentrations of the endogenous opioid peptides methionine enkephalin and leucine enkephalin. As an initial investigation to determine whether opioid peptides contribute to any of the clinical manifestations of hepatic disease nalmefene, a specific opioid antagonist devoid of agonist activity, was given to 11 patients with cirrhosis. They all experienced a severe opioid withdrawal reaction on starting the drug. In the nine patients with primary biliary cirrhosis pruritus was greatly alleviated, fatigue seemed to improve, and plasma bilirubin concentration, which had been rising, showed a modest fall in all except one patient. These results indicate that blocking opioid receptors has an effect on some of the metabolic abnormalities of liver disease.

  • Patients with high opioidergic tone may experience an opiate withdrawal-like reaction to opioid antagonists, characterized by abdominal pain, high blood pressure, tachycardia, goose bumps, nightmares, and depersonalization.

    “Patients with high opioidergic tone may experience an opiate withdrawal-like reaction to opioid antagonists, characterized by abdominal pain, high blood pressure, tachycardia, goose bumps, nightmares, and depersonalization.(201)(202)(203)(204)”

    From Primary Biliary Cholangitis: 2018 Practice Guidance from the American Association for the Study of Liver Diseases (2019) · cites this paper as [202]

    The Discussion (p. 1502) describes an apparent withdrawal reaction after opioid antagonism in patients with raised opioid-peptide concentrations, including abdominal pain and increased arterial pressure. It explicitly says these patients had relative bradycardia, not tachycardia. The Results (p. 1502) do not report goose bumps, nightmares, or depersonalization. (LLM, conf=0.89)

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.
