Abstract: Background: Standard Infliximab infusion consists of a 2-hour intravenous administration. Recently, Infliximab shortened infusion has been included in the Infliximab label as possible maintenance regimen for patients tolerating Infliximab induction therapy. Aim: To verify if accelerated 1-hour Infliximab infusions are as safe as standard administrations, in patients with Inflammatory Bowel Disease. Methods: Seventy-four patients treated between September 2008 and November 2014 were evaluated. Patients were eligible for 1-hour infusion if they had no history of infusion reactions during the previous 2-hour infusions. Results: Twenty-three patients received 2-hour infusions, 16 patients received 1-hour infusions, 35 patients received 2-hour infusions followed by 1-hour infusions. A total of 1,123 Infliximab infusions were administered. The proportion of patients experiencing infusion reaction was: 4% over the 1-hour infusions and 9% over the 2-hour (P = 0.318). Adverse reaction/infusion rate was 0.55% over the 1-hour infusions and 0.66% over the 2-hour (P = 0.835). In the logistic model, accelerated infusion was the only statistically significant predictor of infusion reaction risk reduction (-90%; P = 0.024). Mean satisfaction was 8/10 (±0.84) with 1-hour regimen and 6/10 (±0.56) with 2-hour infusions (P = 0.000). The mean total cost was reduced by 47% with the 1-hour regimen (133.54€ and 250.86€ for 1-hour and 2-hour infusions, respectively). Conclusions: Accelerated Infliximab infusion does not increase the acute infusion reaction incidence. In patients with inflammatory bowel disease, the 1-hour regimen should be preferred to 2-hour protocol also due to positive effects on indirect costs and patient’s satisfaction.
