Off-label use of biologics in urticarial vasculitis: a European retrospective cohort study.

Objectives: Urticarial vasculitis (UV) is characterized by atypical urticarial lesions and leukocytoclastic vasculitis, sometimes with extracutaneous manifestations. First-line treatment is based on colchicine, hydroxychloroquine, dapsone or low-dose glucocorticoids. In refractory forms, the use of biologics has been anecdotally described as potentially effective.

Generation of human induced pluripotent stem cell lines (iPSC) from adipose-derived mesenchymal stromal cells from two patients with systemic sclerosis.

Systemic sclerosis (SSc) is a rare and complex connective tissue disease associated with high morbidity and mortality. SSc is characterized by ischemic vasculopathy, cutaneous and visceral fibrosis and a dysimmune state (Denton and Khanna, 2017; Volkmann et al., 2023; Barnes and Mayes, 2012).

Usefulness of monitoring mycophenolic acid exposure in systemic sclerosis-related interstitial lung disease: a retrospective cohort study.

Background: Systemic sclerosis-related interstitial lung disease (SSc-ILD) represents a significant cause of morbidity and mortality in Systemic Sclerosis (SSc). Mycophenolate mofetil (MMF) is currently the first line treatment for SSc-ILD. There is no recommendation on the dosage of mycophenolic acid (MPA) blood concentrations, so we aimed to study the correlation between MPA exposure and respiratory outcomes in this population.

[Health literacy: Definition, assessment tools, state of the art in Europe, health consequences and ways to improve it].

The term "littératie" is derived from the English word "literacy", which refers to knowledge and skills in the fields of reading, writing, speech (or other means of communication) and calculation that allow people to be efficient and integrated into society. Health literacy is a recent concept that relies on the ability to find, understand, evaluate and communicate information in ways that promote, maintain and improve the health of the individual in various settings over the course of life. The objectives of this review are first of all to realize an overview on the health literacy of populations in Europe.

Tell-tale immune-related neurological syndromes: Should we look for and underlying low-grade B-cell lymphoma? A retrospective study on 12 cases.

Introduction: Immune-related neurological syndromes (affecting both the central and peripheral nervous system, as well as the neuromuscular junction) can associate with low-grade B-cell lymphomas.

Methods: We conducted a retrospective study on the records of patients with miscellaneous immune-related neuropathies followed by the "Referral Centre for Neuromuscular Diseases and ALS" in collaboration with the Services of Internal Medicine and Hematology (La Timone Hospital, and the Paoli Calmettes-Insitute, Marseille, France; Geneva University Hospitals, Geneva, Switzerland). Clinical, biological, immunological and histological work-up was carried out and data collected.

Heart rate variability helps classify phenotype in systemic sclerosis.

We aimed to develop a systemic sclerosis (SSc) subtypes classifier tool to be used at the patient's bedside. We compared the heart rate variability (HRV) at rest (5-min) and in response to orthostatism (5-min) of patients (n = 58) having diffuse (n = 16, dcSSc) and limited (n = 38, lcSSc) cutaneous forms. The HRV was evaluated from the beat-to-beat RR intervals in time-, frequency-, and nonlinear-domains.

Acute Appendicitis in the Elderly: A Nationwide Retrospective Analysis.

Acute appendicitis (AA) in older individuals remains understudied. We aimed to assess AA characteristics in patients older than 60 years and evaluate the impact of comorbidities. This retrospective study analyzed data from the American National Inpatient Sample between 2016 and 2019 to compare AA characteristics in patients younger and older than 60 years.

[Intranodal palisaded myofibroblastome: A rare cause of inguinal lymphadenopathy].

Introduction: Lymphadenopathies are a major cause of consultation in internal medicine, with various causes of diagnosis. Unexplained persistent lymphadenopathy must be biopsied to rule out malignant tumor.

Case Report: We report the case of a 53-year-old man, with inguinal lymphadenopathy evolving for more than one year.

[High anti-topoisomerase-1 autoantibodies levels are associated with the extension of skin fibrosis and vascular progression in patients with systemic sclerosis].

Background: Anti-centromere antibodies, anti-topoisomerase-1 antibodies (ATA), and anti-RNA-polymerase III antibodies are three Systemic Sclerosis (SSc)-specific autoantibodies. Their detection is helpful in determining the prognosis. We aimed to evaluate whether ATA levels were associated with disease severity at diagnosis or disease progression during follow-up in ATA positive patients.

Molecular B-cell clonality assay in minor salivary glands as a useful tool for the lymphoma risk assessment in Sjögren's syndrome.

Objectives: Non-Hodgkin's lymphoma (NHL) risk assessment is crucial in Sjögren's syndrome (SS). We studied the prevalence of clonal immunoglobulin gene rearrangements in minor salivary glands (MSG) and their correlations with lymphoma occurrence and with previously established NHL predictors.

Methods: Molecular B-cell expansion was studied in fresh-frozen MSG of 207 patients with either suspected SS or with suspected lymphoma during SS, using a standardised multiplex PCR assay combined with heteroduplex analysis by microcapillary electrophoresis.

[Hospitalization for infection in patients treated for giant cell arteritis: A single-centre retrospective study].

Introduction: Infections are associated with morbimortality of patients with giant cell arteritis (GCA). The aim of this work was twofold: the identification of factors predisposing to the risk of infection and the description of patients hospitalized with an infection occurring during the treatment period of CAG.

Methods: A monocentric retrospective study was conducted in GCA patients, comparing patients hospitalized for infection with patients without infection.

Adipose Tissue and Adipose-Tissue-Derived Cell Therapies for the Treatment of the Face and Hands of Patients Suffering from Systemic Sclerosis.

Adipose tissue is recognized as a valuable source of cells with angiogenic, immunomodulatory, reparative and antifibrotic properties and emerged as a therapeutic alternative for the regeneration and repair of damaged tissues. The use of adipose-tissue-based therapy is expanding in autoimmune diseases, particularly in Systemic Sclerosis (SSc), a disease in which hands and face are severely affected, leading to disability and a decrease in quality of life. Combining the advantage of an abundant supply of fat tissue and a high abundance of stem/stromal cells, fat grafting and adipose tissue-derived cell-based therapies are attractive therapeutic options in SSc.

Predictors of Relapses or Recurrences in Patients With Giant Cell Arteritis: A Medical Records Review Study.

Objective: Giant cell arteritis (GCA) is the most common systemic vasculitis in individuals aged ≥50 years. Its course is marked by a high relapse rate requiring long-term glucocorticoid use with its inherent adverse effects. We aimed to identify factors associated with relapses or recurrences in GCA at diagnosis.

CD146 at the Interface between Oxidative Stress and the Wnt Signaling Pathway in Systemic Sclerosis.

CD146 involvement was recently described in skin fibrosis of systemic sclerosis through its regulation of the Wnt pathway. Because the interaction between Wnt and ROS signaling plays a major role in fibrosis, we hypothesized that in systemic sclerosis, CD146 may regulate Wnt/ROS crosstalk. Using a transcriptomic and western blot analysis performed on CD146 wild-type or knockout mouse embryonic fibroblasts, we showed a procanonical Wnt hallmark in the absence of CD146 that is reversed when CD146 expression is restored.
