What is the evidence that anti‑TNF is superior to vedolizumab for inducing remission in chronic antibiotic‑refractory pouchitis

What is known

- Anti-TNF (infliximab/adalimumab) induces remission in ~50–53% of chronic antibiotic-refractory pouchitis (CARP) patients, while pooled vedolizumab data show ~75% week-12 clinical response. ^1,2 - Where compared, the data point if anything toward vedolizumab being at least equivalent and better tolerated long-term. ^1,3

What is unknown / caveats

- There is no robust head-to-head evidence establishing anti-TNF superiority over vedolizumab in CARP - The data are observational - The ~50–53% and ~75% figures come from separate uncontrolled series with different endpoints, not a direct comparison.
