Abstract

Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible, and typically fatal lung disease characterised by subpleural fibrosis, subepithelial fibroblast foci, and microscopic honeycombing. Although understanding of the pathogenic mechanisms continues to evolve, evidence indicates that distal airway and alveolar epithelial cells are central drivers of the disease. In this Viewpoint, we review the history of naming and classifications used to define the disease now referred to as IPF, in the context of understanding the clinical presentation, causes, and pathogenesis of the disease. We aim to generate discussion on whether, given the substantial progress made in understanding the clinical, genetic, cellular, and molecular mechanisms involved in the development of IPF, a change of name should be considered. To initiate this discussion, we offer new suggestions to update the name of this disease and new approaches to classify all forms of pulmonary fibrosis.

  • BLM-injury promotes the synthesis and release of TGF-β1 by lung epithelial cells.

    “Based on the previous report that BLM-injury promotes the synthesis and release of TGF-β1 by lung epithelial cells 69”

    From Nicotinamide phosphoribosyltransferase prompts bleomycin-induced pulmonary fibrosis by driving macrophage M2 polarization in mice (2024) · cites this paper as [69]

    The section “Primary role of lung epithelia in disease pathogenesis” says abnormal lung epithelium expresses mediators that include TGF-β. It does not say that bleomycin (BLM) injury promotes epithelial synthesis and release of TGF-β1; searches for bleomycin and that mechanism found no supporting passage.

  • Environmental factors linked to IPF pathogenesis include cigarette smoke, occupational exposure to wood, metal and silica dust, air pollution (particulate matter and nitrogen dioxide), GERD, and viral infections.

    “Environmental factors linked to IPF pathogenesis include cigarette smoke, occupational exposure to certain substances in the workplace, such as wood, metal and silica dust, air pollution, particularly particulate matter and nitrogen dioxide, gastroesophageal reflux disease (GERD) and viral infections (Raghu & Meyer, 2012; Wolters et al., 2018).”

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.
