Az adalimumab a tumornekrózis-faktor-alfát célzó, teljesen humán monoklonális antitest, amely randomizált klinikai vizsgálatokban hatékonynak bizonyult a Crohn-betegség kezelésében. A jelen tanulmányban a szerzők célja a középtávú klinikai hatásosság és a nyálkahártya-gyógyulás prediktorainak meghatározása volt a magyarországi speciális gasztroenterológiai centrumokban adalimumabkezelésben részesülő Crohn-betegekben. Módszer: A tanulmányba 201 Crohn-beteget vontak be. A klinikai adatok prospektíven kerültek rögzítésre, majd később feldogozásra (férfi/nő arány: 112/89; median életkor: 24 év; időtartam: nyolc év). Korábbi infliximabterápiában 97 (48,3%) beteg részesült, párhuzamosan kortikoszteroidot kapott a betegek 41,3%-a és azathioprint a betegek 69,2%-a (mindkettőt: 26,4%). Eredmények: A klinikai javulás és remisszió aránya a 24. héten 78% és 52%, illetve az 52. héten 69,4% és 44,4% volt. Az endoszkópos kép javulása, illetve a nyálkahártya-gyógyulás a betegek 43,1 és 23,6%-ában volt kimutatható. Logisztikus regressziós modellben a 12 hónapos klinikai kimenetel független prediktorai a klinikai válasz és normális C-reaktív fehérje a kezelés 12. hetében, a kombinált immunszuppresszió szükségessége az indukciós kezelés során, a rövidebb betegségtartam és a dohányzás voltak. A kezelés 12. hetében mért normális C-reaktív fehérje, a 24. héten tapasztalt klinikai remisszió, a korábbi relapsusok gyakorisága és a dohányzás állt összefüggésben a nyálkahártya-gyógyulás mértékével. A dózis emelésére a betegek 16,4%-ának volt szüksége. A párhuzamos azathioprinkezelés és a 12. héten tapasztalt klinikai remisszió csökkentette a dózisemelés esélyét. Következtetés: Az adalimumabkezelés során a középtávú klinikai hatékonyság és a nyálkahártya-gyógyulás előrejelzésében meghatározó tényezők a 12. héten tapasztalt klinikai hatékonyság és normális C-reaktív fehérje, a kombinált immunszuppresszió szükségessége, a luminalis betegség és a dohányzás voltak. A párhuzamos azathioprinkezelés csökkentheti a dózisemelés valószínűségét. Orv. Hetil., 2011, 152, 1433–1442.
