Objectives: Vacuoles, E1 enzyme, X-linked, autoinflammatory and somatic (VEXAS) syndrome is an adult-onset autoinflammatory disease associated with somatic ubiquitin-like modifier-activating enzyme 1 (UBA1) mutations. We aimed to evaluate the efficacy and safety of targeted therapies.

Methods: Multicentre retrospective study including patients with genetically proven VEXAS syndrome who had received at least one targeted therapy.

VEXAS syndrome: A new mimicker of idiopathic multicentric Castleman disease.

Introduction: Idiopathic Multicentric Castleman Disease (iMCD) is a complex and poorly understood pathophysiological entity, which encompasses a variety of conditions and can mimic or be associated with autoimmune/autoinflammatory diseases, making it challenging to diagnose and treat. Vacuoles, Enzyme E1, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome is an adult-onset autoinflammatory disorder associated with hematological abnormalities and caused by acquired somatic mutations in the ubiquitin-like modifier activating enzyme 1 gene (UBA1) which shares several common clinical and biological signs with iMCD. In this article, we report a patient with VEXAS syndrome initially presenting as iMCD, questioning the link between these two entities.

Frequency and characteristics of severe relapse in giant cell arteritis.

Objectives: To assess the frequency and characteristics of severe relapse in patients with giant cell arteritis (GCA) in a real-life setting.

Methods: In a monocentric database of 530 patients, we retrospectively analysed patients who experienced at least one relapse and distinguished severe from nonsevere relapses. Severe relapse was defined by the occurrence of an ischaemic event (ophthalmologic, neurologic, digestive, limb ischaemia), the occurrence of an aortic complication (i.

Evolution of the Therapeutic Management of Giant Cell Arteritis: Analysis of Real-Life Practices over Two Timeframes (2014-2017 and 2018-2020).

To determine how therapeutic strategies for giant cell arteritis (GCA), especially glucocorticoid (GC) management, evolved between 2014 and 2020. Consecutive GCA patients followed for at least 24 months in a single tertiary center were enrolled and separated into two groups: those diagnosed from 2014 to 2017 and those diagnosed from 2018 to 2020. GC doses (mg/kg/day) were analyzed at onset, at Month 3 (M3) and, if continued, at M6, M12, M18 and M24.

Efficacy and tolerance of methotrexate in a real-life monocentric cohort of patients with giant cell arteritis.

Objectives: To assess the indications, efficiency and tolerance profiles of methotrexate (MTX) in patients with giant cell arteritis (GCA) in a real-life setting.

Methods: From a monocentric database of >500 GCA patients, we retrospectively selected 49 patients who received MTX between 2010 and 2020. Cumulative glucocorticoid (GC) doses, the number of relapses and GC-related adverse events were recorded before, during and after MTX.

Drugs associated with systemic sclerosis: An updated list of suspected drugs using the WHO pharmacovigilance database.

Objective: The pathophysiological mechanisms involved in systemic sclerosis (SSc), especially the triggering factor, are poorly understood. The literature supporting the role of drugs in the onset of SSc primarily relies on case reports, short series or previous studies of old drugs. We aimed to update the list of suspected drugs associated with SSc (DASSc).

Impact of Glucocorticoid Cumulative Doses in a Real-Life Cohort of Patients Affected by Giant Cell Arteritis.

Objectives: To describe the impact of cumulative glucocorticoid (GC) doses on related adverse events (AEs) in giant cell arteritis (GCA) in a real-life setting.

Methods: The medical charts of the last 139 consecutive GCA patients followed in a tertiary centre were retrospectively analysed. The cumulative GC doses were calculated, and the main GC-related AEs were collected during the follow-up.

Tolerance of glucocorticoids in giant cell arteritis: a study of patient-reported adverse events.

Objective: To assess patients' self-reported glucocorticoid (GC)-related adverse events (AEs) in a GCA population.

Methods: A questionnaire was sent to the 100 patients most recently diagnosed with GCA in a tertiary centre. This questionnaire included open- and close-ended questions on the disease and GC effects.

Impact of Giant Cell Arteritis and Its Treatment on the Patient's Quality of Life: A Single-Center Self-Assessment Study.

Little is known about the impact of giant cell arteritis (GCA) and its treatment on patient-reported physical, mental, and psychic quality of life (QoL). In this monocentric study, a questionnaire was sent to the 100 last patients diagnosed with GCA and followed-up in a single tertiary center. Their physical, mental and psychic status were self-assessed via close-ended questions, the 12-item short form survey (SF-12) and the 15-item geriatric depression scale (GDS).

ANCA and anti-glomerular basement membrane double-positive patients: A systematic review of the literature.

Introduction: Double-positive patients (DPP) exhibiting anti-glomerular basement membrane (GBM) and anti-neutrophil cytoplasmic antibodies (ANCAs) belong to an entity that is newly and poorly described, mainly in short series. We aimed to better characterize the epidemiological features, clinical presentation and therapeutic outcomes of these patients through a systematic review.

Methods: We performed a systematic review of English-, German-, Spanish- and French-written publications from February 1987 to March 2020 reporting cases of DPP using the following databases: PubMed, Scielo, ScienceDirect, Google Scholar, The Cochrane Library, Open Grey, The Grey Literature Report, Clinicaltrials.

A Worldwide Pharmacoepidemiologic Update on Drug-Induced Antineutrophil Cytoplasmic Antibody-Associated Vasculitis in the Era of Targeted Therapies.

Objective: The literature supporting the role of a specific drug in the onset of drug-induced antineutrophil cytoplasmic antibody-associated vasculitis (AAV) mainly relies on case reports or short series and implicates old treatments. The advent of new treatments may have modified the epidemiology of these adverse drug reactions. This study was undertaken to update the list of drugs associated with AAV by using a pharmacovigilance-based data mining approach.

Association between familial Mediterranean fever and multiple sclerosis: A case series from the JIR cohort and systematic literature review.

Introduction: Familial Mediterranean fever (FMF) is the most frequent monogenic autoinflammatory disorder; and leads to the uncontrolled production of interleukin (IL)-1β. Multiple sclerosis (MS) is an inflammatory disease of the central nervous system; and its development seems to be partly correlated with IL-1β levels. It is hypothesized that FMF could be associated with MS.
