Background: Drug persistence reflects an agent’s efficacy and safety in routine practice. This study was undertaken to compare the 2-year persistence rates of three biologic disease-modifying antirheumatic drugs (bDMARDs) used to treat rheumatoid arthritis (RA) and to describe their efficacy and safety profiles. Methods: This retrospective, observational, single-center study included RA patients who had received at least one intravenous dose of infliximab, abatacept, and/or tocilizumab. Two-year drug persistence was estimated using the Kaplan–Meier method. Efficacy profiles were assessed as changes of Disease-Activity Score-28 (DAS28)-based EULAR-criteria responses. Results: The infliximab, abatacept, and tocilizumab groups included 40, 72, and 93 patients, respectively. Their respective 2-year persistence rates were similar: 55.0%, 45.8%, and 62.4%. Tocilizumab recipients benefited from greater improvement than those given infliximab (p = 0.0005) or abatacept (p < 0.0001). For all groups combined, 93.1% of patients obtained good or moderate EULAR responses. Conclusions: Even if this retrospective work includes different biases (lack of data, recruitment bias, etc.), it highlights that the 2-year persistence rates for infliximab, abatacept, and tocilizumab in daily practice did not differ significantly, thereby confirming the long-term efficacies of these three bDMARDs. However, tocilizumab was associated with more significant DAS28 improvement at 2 years than infliximab and abatacept.

Background and Aim: Psoriatic arthritis (PsA) is a polymorphic disease associated with numerous comorbidities. The objective of this study was to describe the main clinicobiological and imaging characteristics of a population of PsA and to extract any disparities between men and women. Methods: A total of 132 patients in the rheumatology department of Amiens University Hospital with a confirmed diagnosis of PsA according to the CASPAR criteria were included over a period of 4 months. All data were collected retrospectively in this observational and single-center study. Results: The sex ratio was 1 and the average age at inclusion was 54.9 years. Peripheral PsA was the predominant clinical form. Axial PsA represented 12.1% of cases. Enthesitis was noted in 52.3% of cases while dactylitis was identified in 29.5% of cases. Moreover, 12.1% had a joint symptomatology preceding the appearance of cutaneous signs. HLA-B*27 positivity was found in 33.3% of cases. Chronic hyperuricemia accounted for 10% of our population. Sacroiliitis was observed in 41% of cases. The disparities between men and women are multiple and consistent with the literature: Polyarticular form, enthesitis, obesity, more intensive prescription of s-DMARDs, and b-DMARDs are more associated with the female population. Oligoarticular form, psoriatic nail dystrophy, radiological axial involvement, and chronic hyperuricemia are more encountered in the male population. Conclusions: Our study found a very heterogeneous disease, with marked differences between men and women. Peripheral PsA remains predominant but the search for associated axial involvement, which is probably underestimated, seems essential. Relevance for Patients: This work studied the main characteristics of patients with PsA followed in real life, in a regional university reference center. We have highlighted a very heterogeneous disease as well as some gender disparities, not well described in the literature, which should be taken into account in order to optimize therapeutic management.

BackgroundUltrasound-guided injections are an alternative to evaluate, it eliminates the risk of ionizing radiation for both the patient and the practitioner as fluoroscopic procedures require a radiology technician, increase the overall support time and cost, decrease accessibility.ObjectivesThe main objective of the study was to compare the short-term efficacy of posterior inter-apophyseal joint infiltrations under ultrasound versus scopic guidance.MethodsObservational, retrospective, single-centre study. Patients benefited from posterior zygapophysial joints injection(s) under fluoroscopy or ultrasound and a follow-up consultation at one month.ResultsData from 54 patients was collected. The evolution of VAS at 1 month was on average - 31.4cm (p <0.001) in the ultrasound group and - 31.3cm (p <0.001) in the fluoroscopy group with no statistically significant difference between the two groups (p =0.835). There were no injection-related complications in either group during the follow-up. The decrease in the consumption of NSAIDs was no statistically significant difference between both groups (p = 1.00). Statistically significant differences in procedure time were observed between groups with a longer time recorded for the ultrasound group (p = 0.007).ConclusionA corticosteroid injection of the posterior zygapophysial joints under ultrasound allows for a significant reduction in pain after one month with no difference found between the two techniques. Injection under ultrasound are a reliable, accessible and safe alternative.Disclosure of InterestsNone declared
