Aliment Pharmacol Ther 2011; 34: 181–187 Summary Background Infliximab is a chimeric monoclonal antibody to tumour necrosis factor alpha (TNFα) with efficacy in inducing and maintaining remission of inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis and psoriasis. Infliximab is generally administered over 2 h with a further 1‐h postinfusion observation. This time interval has substantial impact on healthcare resources and is costly in terms of patient’s time away from work. Aim To examine the safety and tolerability of a 1‐h, relative to a 2‐h maintenance of infusion of infliximab, and to determine the effect of corticosteroid premedication and concurrent immunosuppressor use on infusion reaction rates. Method A prospective cohort study with variable follow‐up duration of 2165 consecutive infliximab infusions in 415 patients during 2009 was conducted. Diagnosis, infusion episode number, infusion rate, premedication, concurrent immunosuppressor therapy, the nature and the outcome of infusion reactions were examined. Results The majority of infusions (74%) were for management of inflammatory bowel disease. Infusion reactions clustered within the first eight infusions with subsequent sporadic reactions. The infusion reaction incidence rate per 1000 person days in 274 1‐h infusions from 54 patients and 1356 2‐h infusions from 256 patients were 0.08 and 0.28 respectively ( P = 0.07). Poisson regression model confirmed that the concurrent use of immunosuppressor therapy was associated with a lower infusion reaction rate, whereas corticosteroid premedication was not. Conclusions During maintenance therapy, infliximab infusion can be safely administered over 1 h in patients with no past history of significant infliximab infusion reaction. Corticosteroid premedication had no impact on the infusion reaction rates.
