A report on the adverse events of special interest from the Romanian Registry of Rheumatic Diseases in patients treated with biologic and targeted synthetic disease-modifying anti-rheumatic drugs during 2022

Background. The evolution of the therapeutic arsenal in inflammatory rheumatic diseases has dramatically improved their evolution and prognosis. On the other hand, the information of the safety data, especially for conditions that may appear in a longer time of exposure, are not reflected by clinical trials, due to their limited time design. Patient registries are a valuable source of safety data applicable to real-world (unselected) patients. The evaluation of these data completes the evidence from the various development programs, with the aim of more concrete knowledge of each therapeutic class (therapeutic agent). Aim. The present report descriptively presents the adverse events (AE) of special interest, recorded by the Romanian Registry of Rheumatic Diseases (RRBR), during 2022, in relation to the dynamics of the recent years. Methods. The observational study included all AEs reported in the RRBR in 2022, their severity class, the relationship with exposure to the therapeutic agent. Results. For a cohort of 10676 patients who were exposed to at least one course of treatment, with data in the RRBR during 2022, there were 669 AEs reported: 432 reports for patients with rheumatoid arthritis (RA), 195 records for patients with ankylosing spondylitis (AS) and 42 reports for patients with psoriatic arthritis (PsA). The most common AEs were infections, especially in RA patients. Of all AEs, 94 (14%) were serious AEs, the majority reported in the RA group (16%). A number of 15 MACE, 13 solid malignancy and 19 deaths were reported in the last year. Conclusion. The distribution of EA by disease, the dominance in RA, as well as the distribution by therapeutic groups is in accordance with scientific data, with the exception of breast cancer, which is more frequently reported in RRBR. EA are underreported in the destinated section in the RRBR, an aspect that gives a limit of this report. This represents an unmet need in terms of safety data reporting, that calls for increased knowledge of EA reporting requirements

Treatment of axial spondyloarthritis patients with biologic disease-modifying anti-rheumatic drugs in 2022 - data from the Romanian Registry of Rheumatic Diseases

Objective. The objective of this cross-sectional study was to analyze data available in the Romanian Registry of Rheumatic Diseases (RRBR) in 2022 for axial spondyloarthritis (axSpA) patients treated with biologic disease modifying anti-rheumatic drugs (bDMARDs). Methods. From the RRBR electronic database were collected multiple variables, including patient’s demographic and clinical characteristics, treatment characteristics, patterns of treatment use (initiations, continuations, switching, tapering), and treatment efficacy data of axSpA patients, from 1 January 2022 to 31 December 2022. Results. In 2022, a total of 4315 axSpA patients were registered in the RRBR database: 70% were men, 48.4 years mean age, 13.3 years mean disease duration, 90% with radiographic axSpA, with high prevalence of extra-musculoskeletal manifestations and cardiovascular comorbidities. Most patients (88%) were treated with a tumor necrosis factor inhibitor (TNFi), usually in monotherapy. The most frequently prescribed bDMARDs were adalimumab (36%), etanercept (32%) and secukinumab (12%). The uptake of biosimilars reached one third of patients from molecules with available biosimilars in 2022. Most patients had a good clinical response, irrespective of clinical form, disease duration, type of medication or line of treatment. Medication switching was needed in 10% of patients, the main reason for switching was secondary loss of efficacy. Medication tapering was implemented in 11% of patients, and it was successful in 90% of cases. Conclusion. Data from RRBR provide a valuable real-world view of clinical practice at the national level regarding biologic treatment of axSpA patients

Differences and similarities between the EULAR/ASAS-EULAR and national recommendations for treatment of patients with psoriatic arthritis and axial spondyloarthritis across Europe

This is the first report comparing EULAR and national treatment recommendations for PsA patients across Europe, and the first this decade to compare ASAS-EULAR and national treatment recommendations in axSpA patients. An electronic survey was completed from October 2021–April 2022 by rheumatologists in 15 European countries. One and four countries followed all EULAR and ASAS-EULAR recommendations, respectively. Five countries had no national treatment recommendations for PsA and/or axSpA, but followed other regulations. In several countries, national treatment recommendations predated the most recent EULAR/ASAS-EULAR recommendations. Entry criteria for starting biologic/targeted synthetic disease-modifying anti-rheumatic drugs varied considerably. In several countries, for PsA patients with significant skin involvement, interleukin-17 inhibitors were not given preference. The positioning of Janus Kinase inhibitors differed and Phosphodiesterase-4 inhibitors were not in use/reimbursed in most countries. This study may motivate European countries to update their national treatment recommendations, to align them better with the latest international recommendations

Antioxidant properties of alpha-lipoic acid: effects on red blood membrane permeability and adaptation of isolated rat heart to reversible ischemia

International audienceThe aim of our work was to study (1) the antioxidant properties of lipoic acid (LA) and its reduced metabolite dihydrolipoic acid (DHLA) formed by reduction of LA and (2) the effects of treatment with LA and DHLA on (a) K ? efflux from human red blood cells and (b) postischemic recovery and oxidative stress in isolated perfused rat hearts challenged with an ischemia-reperfusion (IR) sequence. In vitro, we used xanthine and xanthine oxidase to generate superoxide anion, which is not directly measurable by electron paramagnetic resonance (EPR), but specifically oxidizes the spin probe CPH into an EPR-detectable long lasting CP • nitroxide radical. While 5 mM of LA was ineffective in reducing the kinetics of CP • nitroxide formation, DHLA was shown to lessen this rate in a dose-dependent manner and at 30 mM was even more efficient than 300 UI/ ml SOD. These results are in agreement with the fact that DHLA is able to directly scavenge superoxide anion. Red cells are a good model to investigate oxidative damage in biological membranes; hence, we used a suspension of erythrocytes incubated with 2,2 0-azobis(2-amidinopropane) hydrochloride (AAPH) which generates in vitro free radicals. DHLA provided more effective protection of red cells membranes than LA; DHLA was comparable to Trolox for its antioxidant potency. In vivo, treatment of rats (50 mg/kg/ day i.p. for 7 days) with LA induced a slight increase in coronary flow (CF) in isolated perfused hearts, after 30 min of global total ischemia. This effect was not associated with an improvement in contractile function and reduction of myocardial oxidative stress. In conclusion, because of their ability to scavenge free radicals, LA and to an even greater degree DHLA were able to protect the membranes of red blood cells. This finding suggests that LA and DHLA might be useful in the treatment of diseases associated with oxidative stress such as diabetes
