Abstract

BACKGROUND: The pulmonary antioxidant glutathione may limit airway inflammation in asthma. Since paracetamol (acetaminophen) depletes the lung of glutathione in animals, a study was undertaken to investigate whether frequent use in humans was associated with asthma. METHODS: Information was collected on the use of analgesics as part of a population based case-control study of dietary antioxidants and asthma in adults aged 16-49 years registered with 40 general practices in Greenwich, South London. The frequency of use of paracetamol and aspirin was compared in 664 individuals with asthma and in 910 without asthma. Asthma was defined by positive responses to questions about asthma attacks, asthma medication, or waking at night with shortness of breath. The association between analgesic use and severity of disease amongst asthma cases, as measured by a quality of life score, was also examined. RESULTS: Paracetamol use was positively associated with asthma. After controlling for potential confounding factors the odds ratio for asthma, compared with never users, was 1.06 (95% CI 0.77 to 1.45) in infrequent users (

  • Depletion of glutathione in airway epithelial lining fluid by paracetamol metabolites has been suggested as a possible cause of asthma in chronic users.

    “Depletion of glutathione in airway epithelial lining fluid by paracetamol metabolites has been suggested as the possible cause (192).”

    From Paracetamol: New Vistas of an Old Drug (2006) · cites this paper as [192]

    The Discussion proposes that frequent paracetamol use could contribute to asthma morbidity by depleting glutathione in airway epithelial lining fluid. However, the paper attributes depletion by a reactive paracetamol metabolite to the liver; it does not establish that metabolites deplete glutathione in airway lining fluid. (LLM, conf=0.86)

  • There is increased evidence of asthma in chronic paracetamol users.

    “Finally, it is worth mentioning an increased evidence of asthma in chronic paracetamol users (17,192).”

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.
