Rifaximin for sekundær forebygging av tilbakevendende pouchitis
30. juli 2026 oppdatert av: University of North Carolina, Chapel Hill
Selv om mange mennesker vil utvikle tilbakevendende pouchitt (betennelse i ileal pouch-anal anastomose eller J-pouch etter kolektomi for ulcerøs kolitt) etter en første episode av pouchitt, er det foreløpig ingen effektive behandlinger for å forhindre tilbakevendende pouchitt.
Målet med denne studien er å evaluere potensialet for rifaximin, et antibiotikum, for å forhindre tilbakevendende pouchitt etter behandling for en første episode av pouchitis.
I denne studien vil alle pasienter få daglig rifaximin i ett år etter å ha blitt behandlet for en første episode med pouchitt.
Denne studien vil undersøke om folk er villige til å ta rifaximin i ett år med mål om å forhindre tilbakevendende pouchitt.
I tillegg vil denne studien undersøke om pasienter opplever noen uventede bivirkninger av rifaximinbehandling.
Informasjonen oppnådd gjennom denne studien vil potensielt være nyttig for å forbedre vår evne til å forhindre tilbakevendende pouchitt hos pasienter som har en kolektomi for ulcerøs kolitt.
