Background: Pneumococcal vaccination is recommended for patients with rheumatoid arthritis. Because immunosuppressant therapies for rheumatoid arthritis hinder vaccine efficacy, vaccination should be administered before initiating immunosuppressive drugs. We aimed to compare humoral responses in patients with rheumatoid arthritis receiving the pneumococcal 13-valent conjugate vaccine (PCV13) before methotrexate initiation or simultaneously.

Introduction: Biological disease modifying antirheumatic drugs (bDMARDs) have a central role in the treatment of rheumatoid arthritis (RA). Tumour necrosis factor inhibitors (TNFis) are commonly used as first-line agents, while non-TNFis (tocilizumab, abatacept and rituximab) have shown to be non-inferior to TNFis in head-to-head trials. In case of TNFi inadequate response, using other mechanisms of action provides a better response than using an alternate TNFi.

Existing guidelines for systemic lupus erythematosus (SLE) predominantly focus on common and major organ involvements. An international taskforce involving experts from three SLE expert groups (ie, the European Reference Network on Rare and Complex Connective Tissue and Musculoskeletal Diseases, the Systemic Lupus Erythematosus International Collaborating Clinics group, and the European Lupus Society) was established. A total of 119 participants contributed to the development of consensus therapeutic strategies for 24 rare SLE manifestations, using a multistep process.

Chimeric antigen receptor (CAR)-based therapies developed for the treatment of haematological malignancies have recently been repurposed to treat refractory systemic autoimmune diseases. In this Review we critically discuss the current data available on the use of CAR-based therapy in systemic autoimmune diseases, the current challenges, and the potential next steps toward their implementation into clinical practice. Beyond the targeting of B cells via CD19, we discuss the advantages and potential pitfalls of targeting plasma cells (B-cell Maturation Antigen or CD138) and other non-immune targets, such as fibroblast activated protein, and of aiming to restore immune homeostasis using CAR T regulatory cells.

Background: Rheumatoid arthritis (RA) is commonly treated with Janus kinase inhibitors (JAKis) and anti-tumor necrosis factor-α (anti-TNFα), but the cardiovascular safety profiles of these drugs remain unclear.

Objective: The aim of this study was to describe the individual case safety reports of major adverse cardiac events (MACE) or stroke and to determine whether there was a difference in the frequency of reporting of cardiovascular events between JAKis and anti-TNFα used in RA.

Methods: A case/non-case study was conducted using the WHO VigiBase database.

Objectives: To compare two strategies-a hydrocortisone replacement strategy and a prednisone tapering strategy-for their success in glucocorticoid discontinuation in patients with rheumatoid arthritis (RA) with low disease activity (LDA).

Methods: The Strategies for glucocorticoid TApering in Rheumatoid arthritis (STAR) study was a double- blind, double-placebo randomised controlled trial including patients with RA receiving a stable dose of glucocorticoid 5 mg/day for ≥3 months and were in LDA for ≥3 months. Patients were randomly assigned in a 1:1 ratio to either replace prednisone with 20 mg/day of hydrocortisone for 3 months, then reduce to 10 mg/day for 3 months before discontinuation or to taper prednisone by 1 mg/day every month until complete discontinuation, contingent on maintaining LDA.

Background: Moderate doses of glucocorticoids result in improvements in nearly all patients with polymyalgia rheumatica, but related adverse events are common in older individuals. We aimed to evaluate whether treatment with baricitinib (a Janus kinase 1/2 inhibitor) results in disease control without the use of oral glucocorticoids in people with recent-onset polymyalgia rheumatica.

Methods: We conducted a randomised, double-blind, placebo-controlled, parallel-group trial at six expert centres in France.

Background: The impact of disease activity and treatment on fertility outcomes in patients with spondyloarthritis (SpA) has been little explored. This study aimed to describe median time to pregnancy (TTP) in women with SpA and the factors influencing TTP in this population.

Methods: This prospective observational multicentre (63 centres) French cohort (GR2 study-NCT02450396) included consecutive women with a diagnosis of SpA (according to their rheumatologist) who wanted to become pregnant between 2015 and 2021.

Article Synopsis
  • The purpose of this project was to update the 2016 recommendations regarding the management of immunosuppressants or biologics in patients with giant cell arteritis (GCA).
  • A task force of 18 physicians developed 26 validated recommendations after thorough discussion and a >85% consensus process.
  • Key recommendations include using subcutaneous tocilizumab (TCZ) as a first-line treatment when glucocorticoid-sparing is needed, initiating TCZ at diagnosis for patients with specific high-risk conditions, and considering TCZ or methotrexate if glucocorticoid discontinuation is not feasible after 12 months.

Article Synopsis
  • Giant cell arteritis (GCA) primarily affects women over 50, causing symptoms like headaches and jaw pain, and can lead to severe complications like vision loss due to eye involvement.
  • Diagnosis relies on advanced imaging techniques such as FDG-PET and CT scans, while the temporal artery biopsy is considered the gold standard.
  • Urgent treatment with high doses of corticosteroids is critical to prevent vision loss, and long-term management is necessary to monitor for recurrence and potential cardiovascular issues.

Chronic histiocytic intervillositis of unknown origin (CHI) is a rare placental disorder associated with adverse pregnancy outcomes, frequent recurrence, and a lack of effective preventive strategies. Recent insights indicate a potential link between CHI-associated inflammatory lesions and the inflammasome pathway, suggesting innovative therapeutic avenues. Here we show a potential role of the inflammasome pathway in CHI through comprehensive transcriptomic analysis of grade 2 or 3 histopathologic CHI samples, paired with placental controls.

Because Systemic Lupus Erythematosus (SLE) is a rare disease, and due to the significant prognostic impact of early management, a diagnosis confirmed by a physician with experience in SLE is recommended, for example from an expert center. Once the diagnosis is confirmed, existing manifestations should be identified in particular, renal involvement by an assessment of proteinuria, disease activity and severity should be determined, potential complications anticipated, associated diseases searched for, and the patient's socioprofessional and family context noted. Therapeutic management of SLE includes patient education on recognizing symptoms, understanding disease progression as well as when they should seek medical advice.
