Background And Aims: Systemic sclerosis (SSc) is an autoimmune connective disease characterised by excessive extracellular matrix deposition and widespread skin and internal organ fibrosis including various cardiac manifestations. Heart involvement is one of the leading causes of death among patients with SSc. In this study, we aimed to assess the effect of various vasodilator treatments.

Activated protein C (APC) sensitivity is involved in thrombotic events in antiphospholipid syndrome patients. We summarized methods used to assess APC sensitivity with TGA and evaluated the prognostic role of APC resistance through literature search.

Objectives: Heart involvement is one of the leading causes of death in systemic sclerosis (SSc). The prevalence of SSc-related cardiac involvement is poorly known. Our objective was to investigate the prevalence and prognosis burden of different heart diseases in a nationwide cohort of patients with SSc.

Methods: We performed a prospective cohort study of SLE patients with a 2-year follow-up, using Lupus Patient-Reported Outcome (LupusPRO), Lupus Quality of Life (LupusQoL), Systemic Lupus Erythematosus Quality of Life (SLEQOL) and 36-item Short Form (SF-36) questionnaires. Remission was defined as remission off treatment (ROFT) and remission on treatment (RONT) according to the definitions of remission in SLE consensus.
Objectives: Mediation analyses were conducted to measure the extent to which musculoskeletal (MSK) flares and depression affected physical health through excessive fatigue.
Methods: Mediation analyses were performed in a large multicentre cohort of SLE patients. Domains of the LupusQoL and SLEQOL questionnaires were selected as outcomes, MSK flares according to the SELENA-SLEDAI flare index (SFI-R) score and depression defined by Center for Epidemiologic Studies-Depression scale (CES-D) scale as exposures and different fatigue domains from MFI-20 and LupusQoL questionnaires as mediators.
Background: A new autoinflammatory syndrome related to somatic mutations of UBA1 was recently described and called VEXAS syndrome ('Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic syndrome').
Objectives: To describe clinical characteristics, laboratory findings and outcomes of VEXAS syndrome.
Methods: One hundred and sixteen patients with VEXAS syndrome were referred to a French multicentre registry between November 2020 and May 2021.
Objectives: To compare adult patients' characteristics suffering from idiopathic retroperitoneal fibrosis between "relapse-free" and relapsing patients at the diagnosis and identify factors associated with relapse at initial presentation.
Methods: We conducted a retrospective multicentric study in four hospitals in Eastern France, from 1993 to 2020, of adult patients suffering from idiopathic retroperitoneal fibrosis. We analyzed clinical, biological, and radiological features at diagnosis and during a forty-month follow-up.
Introduction: Anti-glomerular basement membrane (GBM) antibodies are pathogenic antibodies first detected in renal-limited anti-GBM disease and in Goodpasture disease, the latter characterized by rapidly progressive crescentic glomerulonephritis combined with intra-alveolar hemorrhage. Studies have suggested that anti-GBM antibody positivity may be of interest in lupus nephritis (LN). Moreover, severe anti-GBM vasculitis cases in patients with systemic lupus erythematosus (SLE) have been described in the literature, but few studies have assessed the incidence of anti-GBM antibodies in SLE patients.

The protocol was sensitive enough to detect 4 log gene copies of virus. At room temperature, influenza RNA was stable on EWs for at least four days.
View Article and Find Full Text PDFImmune thrombocytopenia (ITP) is a rare autoimmune disease due to autoantibodies targeting platelet glycoproteins (GP). The mechanism of platelet destruction could differ depending on the specificity of antiplatelet antibodies: anti-GPIIb/IIIa antibodies lead to phagocytosis by splenic macrophages, in a Fcγ receptor (FcγR)-dependent manner while anti-GPIb/IX antibodies induce platelet desialylation leading to their destruction by hepatocytes after binding to the Ashwell-Morell receptor, in a FcγR-independent manner. Considering the FcγR-dependent mechanism of action of intravenous immunoglobulins (IVIg), we assumed that the response to IVIg could be less efficient in the presence of anti-GPIb/IX antibodies.

Neutropaenia is a frequent event in SLE occurring in 20%-40% of patients depending on the threshold value of neutrophil count. On a daily basis, the management of neutropaenia in SLE is difficult with several possible causes.

The objective of this study was to assess their predictive value for future thromboembolic events in patients with antiphospholipid antibodies (aPL) or antiphospholipid syndrome.
Methods: This prospective multicenter cohort study included consecutive patients with aPL or systemic lupus erythematosus.
Objective: To explore, at an item-level, the effect of disease activity (DA) on specific health-related quality of life (HRQoL) in SLE patients using an item response theory longitudinal model.
Methods: This prospective longitudinal multicentre French cohort EQUAL followed SLE patients over 2 years. Specific HRQoL according to LupusQoL and SLEQOL was collected every 3 months.
Objective: Fatigue is reported in up to 90% of patients with SLE. This study was conducted to identify the determinants associated with fatigue in a large cohort of patients with SLE, as well as to provide a systematic review of the literature.
Methods: Patients from the Lupus BioBank of the upper Rhein, a large German-French cohort of SLE patients, were included in the FATILUP study if they fulfilled the 1997 ACR criteria for SLE and had Fatigue Scale for Motor and Cognitive Functions scores collected.
Puumala orthohantavirus (PUUV) is the most prevalent of the four species of zoonotic hantaviruses found in Europe, causing nephropathia epidemica, a mild form of hemorrhagic fever with acute kidney injury that presents with elevated serum creatinine level, proteinuria and hematuria. The febrile phase of the infection begins with flu-like syndrome and visual disturbance. Laboratory results can show thrombocytopenia.

Several publications have confirmed this hypothesis, particularly in the intensive care, pneumology and pediatric units. The value of this marker has been identified in vascular cerebral diseases and coronary bypass.
