Background and objective: Infliximab, a monoclonal antibody directed against tumor necrosis factor α (TNFα), is commonly used during flares and on a regular basis to maintain the remission of inflammatory bowel diseases (IBD). It is usually administered in 2-hours infusion and 2 hours of monitoring after as recommended. However, recent reports suggest that infliximab infusions over a shorter period (30 minutes to 1 hour) are well tolerated. We aimed to compare the tolerability of 1-hour and 2-hours infliximab infusions in patients with IBD in our institution.
Methods: We analyzed data from all patients treated with infliximab between 1999 and September 2010. Infliximab was administered in 1-hour infusion and 1 hour monitoring since 2009. Only the early adverse events were analyzed.
Results: Adverse events during infusion were compared between one group of patients who had 1-hour infusion (989 infusions) and the other who had 2-hours infusion (2102 infusions). The incidence of adverse events was 10.6% in the 2-hours infusion group versus 6.3% in the 1-hour infusion group (P=0.36).
Conclusions: These results suggest that the occurrence of infliximab infusion-related adverse events is similar across the two groups, regardless of the infusion cycle. One-hour infusion could then be proposed safely for all patients.
