ABSTRACT
BACKGROUND:
Anti-tumour necrosis factor (TNF) agents play a pivotal role in the treatment of moderate to severe ulcerative colitis (UC), and yet, no international consensus on when to discontinue therapy exists.OBJECTIVE:
The aim of this study is to study the long-term performance of a treatment algorithm of repeated intensified induction therapy with infliximab (IFX) to remission, followed by discontinuation in patients with UC. PATIENTS ANDMETHODS:
Patients with moderate to severe UC were enroled in an open prospective study design. The following algorithm was implemented (a) intensified induction treatment to remission (Ulcerative Colitis Disease Activity Index score 0-2); (b) discontinuation of IFX; and (c) reinduction treatment if relapse. Mucosal gene expression for TNF was measured with qPCR.RESULTS:
A total of 116 patients were included. The median observation time was 47 and 51 months in intention to treat and per protocol. Remission rates of the first three inductions were 95, 93 and 91% per protocol and 83, 56 and 59% by intention to treat. The median time in remission was 40 months per protocol and 34 months by intention to treat. Long-term remission without further anti-TNF treatment during the observation period was obtained for 41%, with a median observation time of 48 months (range 18-129 months). The median time to relapse was 33 and 11 months with/without normalization of mucosal TNF, respectively. The 5-year success rate for maintaining the effect of IFX in the algorithm was 66%.CONCLUSION:
The treatment algorithm is highly effective for achieving long-term clinical remission in UC. Normalization of mucosal TNF gene expression predicts long-term remission upon discontinuation of IFX.
