Narrative review of mechanistic pathways with no primary empirical data
PubMed 40685067 · doi:10.1016/j.lfs.2025.123872
What was done
This narrative review synthesizes evidence on the mechanistic relationships between obstructive sleep apnea, gut dysbiosis, and altered bilirubin metabolism in the context of cardio-renal-hepatic-metabolic disorders.
What was found
The abstract reports no empirical data or quantitative findings. It describes hypothesized mechanistic pathways wherein chronic intermittent hypoxia alters the gut microbiome, particularly BilR-expressing bacteria responsible for bilirubin catabolism, potentially driving hypobilirubinemia and systemic inflammation.
Why it matters
It highlights the gut-liver axis and bilirubin catabolism as conceptual mechanistic links and potential therapeutic targets in sleep apnea-related metabolic morbidity.
Limits
This is a narrative review with no original clinical data, no specified study sample size, and no systematic search methodology. The proposed pathways and biomarkers remain theoretical.
