Abstract
The aim was to evaluate the incidence of serious infusion-related reactions (SIRRs) in RA treated by non-TNF-targeted biologics.
We analysed data from three independent prospective registers, namely autoimmunity and rituximab, Orencia (abatacept) and RA (ORA) and Registry RoAcTEmra (tocilizumab), promoted by the French Society of Rheumatology and including patients with RA. SIRRs were defined by an occurrence during or within 24 h of an infusion and requiring discontinuation of treatment. Characteristics of patients with SIRRs were extracted from the electronic database.
Among the 4145 patients, SIRRs occurred in 100 patients: 56 patients with the rituximab cohort (2.8% or 0.7/100 patient-years), 15 with the abatacept cohort (1.5% or 0.6/100 patient-years) and 29 with tocilizumab (1.9% or 1/100 patient-years). No fatal SIRR occurred. A previous mild infusion reaction to non-TNF-targeted biologics was observed in a quarter of patients with SIRRs. After pooled multivariate analysis, positive anti-CCP was associated with a higher risk of SIRR (odds ratio = 2.5; 95% CI: 1.01, 6.17). Absence of concomitant treatment with a synthetic DMARD tended to be associated with a higher risk of SIRR (odds ratio = 1.67; 95% CI: 1.00, 2.86).
In daily practice, SIRRs are slightly more frequent than in clinical trials and rarely life threatening. In common practice, serological status (anti-CCP positivity) and absence of concomitant treatment with a synthetic DMARD increase the risk of SIRR.
