Zdravljenje

Biološke in napredne terapije v primerjavi

Prvič je bilo zastavljeno primerjalno vprašanje — katera zdravila, ne ali zdravilo — ki ima meta-analitične odgovore.

Kaj se je spremenilo

Dve desetletji je bila osnova dokazov zdravila proti placebu, kar je zdravnikom povedalo, da biologiki delujejo, vendar nič o tem, katero izbrati. Mrežna meta-analiza je to spremenila z uporabo skupnih primerjalnikov za posredno razvrščanje terapij [1][4].

Praktična posledica je, da se lahko zdaj o izbiri prve linije razmišlja, namesto da bi bila privzeta, in razlike med zdravili pri indukciji v primerjavi z vzdrževanjem ter pri učinkovitosti v primerjavi z varnostjo so vidne.

Primerjalna učinkovitost naprednih terapij

Razredi

Razredi naprednih terapij pri IBD
RazredMehanizemOpombe
Anti-TNFBlokira tumor nekrozo faktor alfaNajdaljša zgodovina; imunogenost je glavna omejitev
Anti-integrinBlokira prehajanje levkocitov v črevesjeIzbirno za črevesje, zato ugodna sistemska varnost
Anti-IL-12/23 in anti-IL-23Blokira signalizacijo interlevkinaMočna učinkovitost in varnost v nedavnih primerjavah
JAK inhibitorjiMala molekula, intracelularna signalizacijaPeroralni in hitri; opozorila o kardiovaskularnih težavah in trombozi
S1P modulatorjiZadrži limfocite v limfnih vozlihPeroralni; novejši, manj dolgoročni podatki

Zdravljenje do cilja, ne do simptomov

Najbolj pomembna sprememba v obvladovanju IBD je, da so simptomi slaba proxy za vnetje. Ljudje se dobro počutijo z aktivnim vnetjem in se slabo počutijo v remisiji. Trenutne evropske smernice zato ciljajo na objektivne markerje — fekalni kalprotektin, endoskopsko celjenje — namesto na to, kako se pacient počuti.

To je tudi odgovor na prehransko vprašanje, postavljeno na strani o prehrani: intervencija, ki izboljša simptome, ne da bi izboljšala objektivne markerje, ni zdravila bolezni.

Ko eno zdravilo ni dovolj

Dvojna biologična ali kombinirana terapija z zdravili majhnih molekul je bila ocenjena za refraktorno bolezen [3]. Ostaja specialistična odločitev z omejeno bazo dokazov, in tam, kjer je delo na ravni posameznih celic, ki opredeljuje heterogenost odziva [2], najbolj verjetno, da bo spremenilo prakso — s predvidevanjem, kateri mehanizem ciljati pri določenem pacientu, namesto da bi ga odkrili s zaporednim neuspehom.

Pogosta vprašanja

Kateri biologik je najboljši?
Mrežne meta-analize jih zdaj razvrščajo [1][4], in prava izbira je odvisna od lokacije bolezni, resnosti, zunajčrevesnih značilnosti in vaše lastne tolerance do tveganja.
Ali lahko preneham, ko sem v remisiji?
Prenehanje prinaša znatno tveganje za ponovitev. To je odločitev, ki jo je treba sprejeti s svojo ekipo, na podlagi objektivnih markerjev, ne glede na to, kako se počutite.
So biologiki nevarni?
Nosijo resna tveganja, predvsem okužbe. Nepoškodovano vnetje prav tako nosi tveganje, in primerjava je med dvema tveganjema, ne proti nič.
Kaj je kalprotektin?
Marker blata za črevesno vnetje. Tako se dejansko spremlja "zdravljenje do cilja".
