Clinical registries have shown their effectiveness in capturing the long-term benefit of drugs in routine care. In France, two types of registry have been established to analyse the safety and efficacy of biological agents.


The Research Axed on Tolerance of Biotherapies (RATIO) registry was designed to prospectively collect all cases of lymphoma and opportunistic infections occurring in patients receiving anti-TNF blockers for any indication. We also examined the results from nationwide prospective cohorts in order to investigate the safety and efficacy of rituximab (RTX), abatacept (ABA) and tocilizumab in RA and other autoimmune diseases.


Analysis of the RATIO registry demonstrated an increased risk of Legionella pneumophila infection in patients receiving anti-TNF therapy, a higher risk of tuberculosis [odds ratio (OR) (95% CI): 13.3 (2.6, 69.0) and 17.1 (3.6, 80.6) for infliximab and adalimumab vs etanercept, respectively], opportunistic infections and incidence of lymphoma, with mAb than with soluble-receptor anti-TNF. The characteristics of RA patients in RTX and ABA registries showed that some patients did not receive previous TNF blockers [20% in autoimmunity and RTX (AIR) and 13% in Orencia and RA (ORA)] and one-third of them were treated without concomitant DMARDs. Patients receiving RTX showed an increased proportion of severe infections (5.0/100 patient-years). Lung and cardiac comorbidities, extra-articular involvement and low immunoglobulin G before RTX were predictive factors of severe infections. In addition, the AIR registry suggested the effectiveness of RTX in patients with SLE.


The establishment of biological registries in rheumatic diseases, in France, with their different methods, has already provided additional data to controlled trials, mainly on the risk of severe infections and lymphoma.
