Treatment of non-systemic Sjögren's syndrome: Potential prevention of systematization with immunosuppressant agent/biotherapy.

Sjögren's syndrome (SS) is a systemic autoimmune pathology manifested mainly by a dry syndrome, intense asthenia and arthromyalgia. Systemic manifestations may also occur. Since 2019, immunosuppressant agents (IS) or biotherapies are recommended only for patients with systemic involvement.

Molecular Mechanisms of Endothelialitis in SARS-CoV-2 Infection: Evidence for VE-Cadherin Cleavage by ACE2.

Long COVID-19 syndrome appears after Severe Acute Respiratory Syndrome-Corona Virus (SARS-CoV-2) infection with acute damage to microcapillaries, microthrombi, and endothelialitis. However, the mechanisms involved in these processes remain to be elucidated. All blood vessels are lined with a monolayer of endothelial cells called vascular endothelium, which provides a the major function is to prevent coagulation.

ANCA-associated scleritis: impact of ANCA on presentation, response to therapy and outcome.

Objectives: To describe the characteristics, treatment and outcome of isolated ANCA-associated scleritis at diagnosis compared with idiopathic scleritis with negative ANCA tests.

Methods: This retrospective multicentre case-control study was performed within the French Vasculitis Study Group (FVSG) network and in three French tertiary ophthalmologic centres. Data from patients with scleritis without any systemic manifestation and with positive ANCA results were compared with those of a control group of patients with idiopathic scleritis with negative ANCA tests.

Tocilizumab in Behçet Disease: A Multicenter Study of 30 Patients.

Objective: To evaluate tocilizumab (TCZ) efficacy in patients with refractory Behçet disease (BD).

Methods: This is a multicenter study of 30 patients fulfilling the international criteria for BD and treated with TCZ at different European referral centers. The clinical response was evaluated at 6 months from TCZ initiation.

Characterisation of a high-risk profile for maternal thrombotic and severe haemorrhagic complications in pregnant women with antiphospholipid syndrome in France (GR2): a multicentre, prospective, observational study.

Background: Prospective data about the risks of thrombotic and severe haemorrhagic complications during pregnancy and post partum are unavailable for women with antiphospholipid syndrome. We aimed to assess thrombotic and haemorrhagic events in a prospective cohort of pregnant women with antiphospholipid syndrome.

Methods: This multicentre, prospective, observational study was done at 76 centres in France.

Unlabelled: Résumé Introduction. Une interprétation fiable de l'albuminémie est essentielle pour l'évaluation nutritionnelle biologique (ENB) de la personne âgée. L'objectif principal était d'évaluer si une formule de correction proposée en cas d'inflammation prolongée pouvait être extrapolée aux situations d'inflammation biologique aiguës : albuminémie corrigée = albuminémie dosée + protéine C réactive (CRP)/25.

Evaluating biological nutritional status in elderly people with unscheduled hospitalisation.

A reliable interpretation of albumin levels is essential when assessing nutrition in elderly people, but this is complex as it is affected by a number of parameters. The main objective of this study was to evaluate whether a correction formula proposed for prolonged inflammation could be extrapolated to acute biological inflammation situations: corrected albuminemia = measured albuminemia + CRP/25. This prospective, single-centre observation study included patients over 65 years of age who were the subject of an unscheduled hospitalisation in the geriatrics and internal medicine departments of Grenoble University Hospital, excluding carriers of active neoplasia, hepatic insufficiency, nephrotic syndrome and those who continued to present with an acute biological inflammation on the eighth day.

Kidney Histopathology Can Predict Kidney Function in ANCA-Associated Vasculitides with Acute Kidney Injury Treated with Plasma Exchanges.

Background: Data from the PEXIVAS trial challenged the role of plasma exchange (PLEX) in ANCA-associated vasculitides (AAV). We aimed to describe kidney biopsy from patients with AAV treated with PLEX, evaluate whether histopathologic findings could predict kidney function, and identify which patients would most benefit from PLEX.

Methods: We performed a multicenter, retrospective study on 188 patients with AAV and AKI treated with PLEX and 237 not treated with PLEX.

Immune thrombocytopenia with clinical significance in systemic lupus erythematosus: a retrospective cohort study of 90 patients.

Objectives: To describe the characteristics, treatment and outcome of patients with immune thrombocytopenia with clinical significance (ITPCS) associated with SLE.

Methods: This retrospective multicentre study included SLE patients who experienced ≥1 ITPCS (defined as ITP with attributable bleeding disorders and/or a platelet count <30×109/l). Other causes of secondary thrombocytopenia were excluded.

Impact of aging on phenotype and prognosis in IgA vasculitis.

Objectives: Immunoglobulin A vasculitis (IgAV) is a small-vessel vasculitis most frequently benign in children while more severe in adults. We aimed to study the impact of age on presentation and outcome of adult IgAV.

Methods: We conducted a nationwide retrospective study including 260 IgAV patients.

New insights on IgA vasculitis with underlying solid tumor: a nationwide French study of 30 patients.

Objective: IgA vasculitis (IgAV) frequently occurs during or after a mucosal infection; it also rarely occurs in patients with cancer. We hypothesized that cancer could impact the baseline characteristics and/or outcome of vasculitis. We aimed to describe the presentation of IgAV in patients with cancer (IgAV ca+) compared to patients without cancer.

Use of Biologics to Treat Relapsing and/or Refractory Eosinophilic Granulomatosis With Polyangiitis: Data From a European Collaborative Study.

Objective: To describe the efficacy and safety of biologics for the treatment of eosinophilic granulomatosis with polyangiitis (EGPA).

Methods: A retrospective European collaborative study was conducted in patients with EGPA who received treatment with biologics for refractory and/or relapsing disease.

Results: Among the 147 patients with EGPA included in the study, 63 received rituximab (RTX), 51 received mepolizumab (MEPO), and 33 received omalizumab (OMA).

Temporal Arteritis Revealing Antineutrophil Cytoplasmic Antibody-Associated Vasculitides: A Case-Control Study.

Objective: Temporal arteritis (TA) is a typical manifestation of giant cell arteritis (GCA). Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are rarely revealed by TA manifestations, leading to a risk of misdiagnosis of GCA and inappropriate treatments. This study was undertaken to describe the clinical, biologic, and histologic presentations and outcomes in cases of TA revealing AAV (TA-AAV) compared to controls with classic GCA.

Screening of hepatitis E in patients presenting for acute neurological disorders.

Introduction: Hepatitis E virus (HEV) infection has been reported to be associated with neurological disorders. However, the real prevalence of acute hepatitis E in those diseases is still unknown. We determined the prevalence of anti-HEV IgM antibody in a population with acute non-traumatic, non-metabolic, non-vascular neurological injury.

Large-vessel vasculitis diagnosed between 50 and 60 years: Case-control study based on 183 cases and 183 controls aged over 60 years.

Background: Age at onset of large-vessel vasculitis (LVV) is commonly used to distinguish giant cell arteritis (GCA) and Takayasu arteritis (TA). However, LVV between age 50 and 60 years may be difficult to classify.

Methods: We conducted a retrospective study including LVV aged between 50 and 60 years at onset (LVV, cases) and compared them to LVV aged over 60 years (LVV, controls).

CpaA Is a Glycan-Specific Adamalysin-like Protease Secreted by Acinetobacter baumannii That Inactivates Coagulation Factor XII.

Antibiotic-resistant is increasingly recognized as a cause of difficult-to-treat nosocomial infections, including pneumonia, wound infections, and bacteremia. Previous studies have demonstrated that the metalloprotease CpaA contributes to virulence and prolongs clotting time when added to human plasma as measured by the activated partial thromboplastin time (aPTT) assay. Here, we show that CpaA interferes with the intrinsic coagulation pathway, also called the contact activation system, in human as well as murine plasma, but has no discernible effect on the extrinsic pathway.
