IBD Evidence

Behandling

Biologiske legemidler og avanserte terapier sammenlignet

For første gang har det komparative spørsmålet — hvilken medisin, ikke om en medisin — meta-analytiske svar.

Hva endret seg

I to tiår var evidensgrunnlaget medisin mot placebo, noe som fortalte klinikere at biologiske legemidler fungerer, men ingenting om hvilken som skulle velges. Nettverksmeta-analyse har endret dette ved å bruke delte sammenlignere for å rangere terapier indirekte [1][4].

Den praktiske konsekvensen er at førstevalg nå kan begrunnes i stedet for å være en standardvalg, og forskjeller mellom midler ved induksjon versus vedlikehold, og ved effekt versus sikkerhet, er synlige.

Sammenlignende effekt av avanserte terapier

Klassene

Avanserte terapiklasser i IBD
KlasseMekanismeNotater
Anti-TNFBlokkerer tumor nekrose faktor alfaLengst erfaring; immunogenisitet er den viktigste begrensningen
Anti-integrinBlokkerer leukocytttrafikk til tarmenTarmselektiv, så gunstig systemisk sikkerhet
Anti-IL-12/23 og anti-IL-23Blokkerer interleukin-signaleringSterk effekt- og sikkerhetsprofil i nylige sammenligninger
JAK-hemmereSmå molekyler, intracellulær signaleringOral og rask; kardiovaskulære og tromboseadvarsler
S1P-modulatorerSequestrerer lymfocytter i lymfeknuterOral; nyere, mindre langsiktige data

Behandle mot mål, ikke mot symptomer

Den mest betydningsfulle endringen i IBD-behandling er at symptomer er en dårlig proxy for betennelse. Folk føler seg bra med aktiv betennelse og føler seg dårlig i remisjon. Nåværende europeiske retningslinjer retter seg derfor mot objektive markører — fecal kalprotektin, endoskopisk helbredelse — snarere enn hvordan pasienten rapporterer å føle seg.

Dette er også svaret på det kostholdsspørsmålet som ble reist på kostholdssiden: en intervensjon som forbedrer symptomer uten å forbedre objektive markører har ikke behandlet sykdommen.

Når én medisin ikke er nok

Dobbelt biologisk eller kombinert småmolekylær terapi har blitt vurdert for refraktær sykdom [3]. Det forblir en spesialistbeslutning med et begrenset evidensgrunnlag, og det er der enkeltcellearbeid som karakteriserer responsheterogenitet [2] mest sannsynlig vil endre praksis — ved å forutsi hvilken mekanisme som skal målrettes i en gitt pasient i stedet for å oppdage det ved sekvensiell svikt.

Vanlige spørsmål

Hvilken biologisk er best?
Nettverksmeta-analyser rangerer dem nå [1][4], og det riktige valget avhenger av sykdomsplassering, alvorlighetsgrad, ekstraintestinale trekk og din egen risikotoleranse.
Kan jeg stoppe når jeg er i remisjon?
Tilbaketrekking medfører betydelig risiko for tilbakefall. Det er en beslutning å ta med teamet ditt, basert på objektive markører snarere enn hvordan du føler deg.
Er biologiske legemidler farlige?
De medfører reelle risikoer, hovedsakelig infeksjon. Ubehandlet betennelse medfører også risiko, og sammenligningen er mellom to risikoer snarere enn mot null.
Hva er kalprotektin for?
En avføringsmarkør for intestinal betennelse. Det er hvordan "behandle mot mål" faktisk overvåkes.
