All disease begins in the (leaky) gut: role of zonulin-mediated gut permeability in the pathogenesis of some chronic inflammatory diseases.
Level 5 - mechanism / opinion, no new human data
Narrative review and mechanistic framework synthesis without systematic search methodology or original clinical data.

What was done
This narrative review synthesized mechanistic concepts and published preclinical and clinical literature regarding the hygiene hypothesis, gut microbiota changes, gastrointestinal mucosal barrier integrity, and the role of zonulin-mediated intestinal permeability in the pathogenesis of chronic inflammatory diseases (CIDs).
What was found
The abstract provides no numerical data, effect sizes, or statistical findings. It conceptually outlines that increased intestinal permeability alters antigen trafficking and bidirectional host-microbiome-immune interactions, proposing that zonulin-family pathway dysregulation is involved in autoimmune, infective, metabolic, and tumoral conditions.
Why it matters
It provides a consolidated mechanistic model linking gut barrier integrity and microbiome dynamics to the rising incidence of systemic inflammatory conditions, pointing toward zonulin pathways as therapeutic targets.
Limits
As an unsystematic narrative review, the paper provides theoretical synthesis rather than empirical human data. The abstract lacks predefined literature search criteria, quality appraisal of cited works, sample size specifications, and quantitative clinical outcomes.
