Environmental factors in primary biliary cirrhosis

Abstract

The etiology of the autoimmune liver disease primary biliary cirrhosis (PBC) remains largely unresolved, owing in large part to the complexity of interaction between environmental and genetic contributors underlying disease development. Observations of disease clustering, differences in geographical prevalence, and seasonality of diagnosis rates suggest the environmental component to PBC is strong, and epidemiological studies have consistently found cigarette smoking and history of urinary tract infection to be associated with PBC. Current evidence implicates molecular mimicry as a primary mechanism driving loss of tolerance and subsequent autoimmunity in PBC, yet other environmentally influenced disease processes are likely to be involved in pathogenesis. In this review, the authors provide an overview of current findings and touch on potential mechanisms behind the environmental component of PBC.

  • Environmental factors likely interact with immunogenetic and epigenetic risk to drive PBC, favouring chronic immune-mediated biliary epithelial injury with cholestasis, ductopenia, and progressive biliary fibrosis.

    “Environmental influences are likely to play a significant role in driving PBC, interacting with immunogenetic and epigenetic risk, favouring chronic immune mediated biliary epithelial injury with subsequent cholestasis, ductopenia, and progressive biliary fibrosis [11][12][13].”

    From EASL Clinical Practice Guidelines: The diagnosis and management of patients with primary biliary cholangitis. (2017) · cites this paper as [11]

    The Abstract and Concluding Remarks describe environmental exposures acting in genetically susceptible people, with loss of immune tolerance and subsequent biliary injury; the Abstract also describes chronic inflammation and destruction of biliary epithelial cells. The copy does not substantiate an interaction with epigenetic risk or the claimed sequence of cholestasis, ductopenia, and progressive biliary fibrosis. Its Smoking and Risk of Primary Biliary Cirrhosis section discusses an association with advanced fibrosis at presentation, not that sequence. (LLM, conf=0.87)

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.
