TNFα is a pro-inflammatory cytokine in Crohn's disease and it's neutralization is beneficial in patients with active disease. Remicade® is a chimeric monoclonal anti-TNF antibody. Remicade® is used in our center since December 1998 in 13 patients who were treated for active disease or fistula. We followed the patients and treatment results in order to estimate the efficacy and safety of this preparation. Response to treatment was measured by the Crohn's Disease Activity Index (CDAI) in patients treated due to active disease, or by the presence of discharge from external fistulae. Five out of seven patients with fistulae had less or no discharge after completing a course of 3 infusions. Four out of 6 patients treated due to active disease improved significantly after a single infusion. Five out of the six needed additional injections due to symptom recurrence. Intervals between infusions were 2 weeks - for fistulae patients to 32 weeks for patients with active disease. Adverse events for the 13 patients were usually mild except for 4 patients that suffered from anaphylactic shock, disseminated eruption (2) and eosinophilic pneumonitis. In summary, treatment of patients with active Crohn's disease or fistulae with monoclonal anti-TNF antibodies is an effective and relatively safe option after established treatment has failed. Analyzing the results of on going clinical trials and of the patients treated off-protocol will enable to establish new treatment strategies for patients with active Crohn's disease and fistulae.
