PRIMARY outcome

Timeframe: 8 weeks

Population: The pre-treatment serum levels of endogenous anti-TNF were zero in all 11 adult patients in whom endogenous anti-TNF was measured. Therefore, pre-treatment serum level of endogenous anti-TNF could not be fully analyzed in relation to primary clinical response or non-response.

Pre-treatment serum level of endogenous anti-TNF are measured and analyzed in relation to primary clinical response or non-response

PRIMARY outcome

Timeframe: 8 weeks

Population: Changes in week 0 and week 8 RNA expression profiles were analyzed within a subgroup of 29 patients (15 children and 14 adults) on infliximab treatment with samples taken at both week 0 and week 8. The number of genes with a 1.5 fold change (FDR value ≤ 0.05; paired t-test) from week 0 to week 8 were assessed for pediatric IBD or adult IBD patients.

Changes in week 0 and week 8 RNA expression profiles were evaluated in relation to the overall population and by study arm, i.e. either pediatric IBD or adult IBD.

SECONDARY outcome

Timeframe: Duration of study (start anti-TNF until 1 year after start of anti-TNF)

Clinical endpoints of Interest were the following: * Primary non-response was defined as no effect of anti-TNF after induction. * Remission and response were assessed at week 8 based on the appropriate disease activity scores for either children with Crohn's disease or ulcerative colitis (PCDAI and PUCAI respectively), or adults with Crohn's disease or ulcerative colitis (CDAI or Mayo score, respectively). * Continued use of anti-TNF was assessed 12 months and 18 months after start of anti-TNF.

SECONDARY outcome

Timeframe: Duration of study (start anti-TNF until 1 year after start of anti-TNF)

Anti-TNF treatment specific outcomes that were considered were: * Dose intensification; increase in dose of anti-TNF compared to standard therapy * Interval shortening; shortening of the interval of anti-TNFadministration compared to standard therapy. * Overall treatment intensification, the number of participants who underwent either dose intensification, interval shortening or both. * Development of Antibodies to infliximab during the course of follow-up * An infliximab serum trough level ≤ 3 mg/ml threshold (standard accepted therapeutic lower threshold) at week 14

Number of participants with concommitant treatment during the study was assessed. Concomitant treatment was defined as: * Additional use of immunomodulators such as methotrexate or azathioprine were registered. * Need for systemic prednisone, for instance in the case of an exacerbation, was assessed.
