Rituximab Versus Conventional Therapy for Remission Induction in Eosinophilic Granulomatosis With Polyangiitis : A Randomized Controlled Trial.

Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is an eosinophilic antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Rituximab has emerged as the standard of care in other types of ANCA-associated vasculitis, but controlled studies on its use in EGPA are yet lacking.

Objective: To compare rituximab with conventional strategy for the induction of remission in patients with EGPA.

Giant cell arteritis mimics with severe consequences: a long-term monocentric inception cohort.

Objectives: To describe patients who underwent a temporal artery biopsy (TAB) for suspected GCA but were given a different diagnosis. We focused on a subset of alternate diagnoses mimicking GCA with ominous consequences of a delayed diagnosis or undue glucocorticoid treatment.

Methods: This was a single-centre retrospective study.

Distinct Pathophysiologic Pathways Support Stratification of Sjögren's Disease Based on Symptoms, Clinical, and Routine Biological Data.

Objective: Recently, three distinct phenotypes of patients with Sjögren disease (SjD) have been described based on cluster analysis: B cell active with low symptoms (BALS), high systemic activity (HSA), and low systemic activity with high symptoms (LSAHS). We aimed to assess whether these clusters were associated with distinct biomarkers and the prognostic value of interferon (IFN) signature.

Methods: The Assessment of Systemic Signs and Evolution in Sjögren's Syndrome cohort is a 20-year prospective cohort of patients with SjD.

Vasodilator drugs and heart-related outcomes in systemic sclerosis: an exploratory analysis.

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.

Upper respiratory tract and orofacial manifestations of new-onset giant cell arteritis: results from a large, prospective inception cohort study.

Objectives: Giant cell arteritis (GCA) often features upper respiratory tract (URT) and orofacial manifestations, which signal the involvement of external carotid artery branches. In this study, we aimed to describe the frequency of various URT/orofacial symptoms at GCA onset, as well as the main characteristics of patients presenting these symptoms.

Methods: We included all patients who were newly diagnosed with GCA between 1976 and April 2022 at the Internal Medicine Department of a tertiary-care hospital.

The functional disabilities of the dominant and opposite hands in patients with systemic sclerosis.

Objectives: Hand involvement in patients with systemic sclerosis (SSc) is responsible for 75% of the overall disability but varies greatly among individuals. No study has yet compared the functionalities between the two hands of SSc patients. We thus evaluated the joint limitations and extent of skin involvement in the dominant and contralateral hands.

Identification of distinct subgroups of Sjögren's disease by cluster analysis based on clinical and biological manifestations: data from the cross-sectional Paris-Saclay and the prospective ASSESS cohorts.

Background: Sjögren's disease is a heterogenous autoimmune disease with a wide range of symptoms-including dryness, fatigue, and pain-in addition to systemic manifestations and an increased risk of lymphoma. We aimed to identify distinct subgroups of the disease, using cluster analysis based on subjective symptoms and clinical and biological manifestations, and to compare the prognoses of patients in these subgroups.

Methods: This study included patients with Sjögren's disease from two independent cohorts in France: the cross-sectional Paris-Saclay cohort and the prospective Assessment of Systemic Signs and Evolution of Sjögren's Syndrome (ASSESS) cohort.

Characterisation of airway disease associated with Sjögren disease.

Objective: Although airway disease associated with Sjögren's disease (Sjo-AD) is common, it is poorly studied compared with interstitial lung disease (ILD). In this study, we aimed to assess factors associated with Sjo-AD, the characteristics and prognosis of this manifestation.

Methods: We performed a retrospective multicentric study involving nine centres.

Use of Complementary and Alternative Medicine by Patients Treated for Systemic Lupus Erythematosus, Primary Sjögren's Syndrome, or Systemic Sclerosis in a French Rural Region.

Background: Complementary and alternative medicine (CAM) is composed of a wide range of interventions and frequently used in parallel with conventional medicine. The aim of this study was to assess the prevalence, modalities, and association factors of CAM utilization in patients treated for systemic lupus erythematosus, primary Sjögren's syndrome, or systemic sclerosis.

Patients And Methods: This was a prospective single-center observational study conducted in a French university hospital center.

Heart and systemic sclerosis-findings from a national cohort study.

Objectives: Heart involvement is one of the leading causes of death in 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.

Frequency and Significance of Hepatic Involvement in New-Onset Giant Cell Arteritis: A Study of 514 Patients.

Abnormalities of liver function in giant cell arteritis (GCA) have long been described and are present at the acute phase of the disease in 30% to 60% of cases. Hepatic involvement is mostly anicteric cholestasis (eg, elevated alkaline phosphatase [ALP] and gamma-glutamyl transferase [GGT]), and, more rarely, cytolytic hepatitis (eg, elevated aspartate aminotransferase [AST] and/or alanine aminotransferase [ALT]).

BOB-ACG study: Pulse methylprednisolone to prevent bilateral ophthalmologic damage in giant cell arteritis. A multicentre retrospective study with propensity score analysis.

Introduction: Giant cell arteritis (GCA) is complicated in 10 to 20% of cases by permanent visual ischemia (PVI). International guidelines advocate the use of intravenous pulse of methylprednisolone from 250 to 1000mg per day, for three days, followed by oral prednisone at 1mg/kg per day. The aim of this study is to assess whether this strategy significantly reduces the risk of early PVI of the second eye, compared with direct prednisone at 1mg/kg per day.

Immune-Mediated Diseases Following COVID-19 Vaccination: Report of a Teaching Hospital-Based Case-Series.

The occurrence and course of immune-mediated diseases (IMDs) following COVID-19 vaccination has been little explored so far. We retrieved, among adult patients hospitalized at the Internal Department of a French university hospital up to May 2022, all those who had developed, or relapsed to, an IMD less than 3 weeks following COVID-19 vaccination, without other triggers. Twenty-seven (24 new-onset) post-COVID-19 vaccine IMDs were recorded.

Temporal artery biopsy: A technical guide and review of its importance and indications.

Temporal artery biopsy (TAB) is a surgical procedure that enables the histological diagnosis of giant cell arteritis (GCA). Performing a TAB requires expertise and a precise approach. Nevertheless, available data supports the value of tissue diagnosis in managing GCA.

Toxoplasmosis in patients with an autoimmune disease and immunosuppressive agents: A multicenter study and literature review.

Background: Cases of Toxoplasma reactivation or more severe primary infection have been reported in patients receiving immunosuppressive (IS) treatment for autoimmune diseases (AID). The purpose of this study was to describe features of toxoplasmosis occurring in patients with AID treated by IS therapy, excluded HIV-positive and transplant patients.

Methods: A multicenter descriptive study was conducted using data from the French National Reference Center for Toxoplasmosis (NRCT) that received DNA extracts or strains isolated from patients, associated with clinical data.

Features and risk factors for new (secondary) permanent visual involvement in giant cell arteritis.

Objectives: New permanent visual loss (PVL) in treated patients with giant cell arteritis (GCA) is a rare but worrisome occurrence. In this study, we aimed to describe the frequency and main features of new PVL occurring after the beginning of glucocorticoid therapy in patients with newly diagnosed GCA.

Methods: We included in an inception cohort all consecutive patients newly diagnosed with GCA in the internal medicine department of a tertiary-care hospital between 1976 and May 2020.

Giant cell arteritis-related stroke in a large inception cohort: A comparative study.

Objective: Stroke caused by giant cell arteritis (GCA) is a rare but devastating condition and early recognition is of critical importance. The features of GCA-related stroke were compared with those of GCA without stroke and atherosclerosis-related or embolic stroke with the aim of more readily diagnosing GCA.

Methods: The study group consisted of 19 patients who experienced GCA-related strokes within an inception cohort (1982-2021) of GCA from the internal medicine department, and the control groups each consisted of 541 GCA patients without a stroke and 40 consecutive patients > 50 years of age with usual first ever stroke from the neurology department of a French university hospital.

Intraoperative findings during temporal artery biopsy: keys to optimise the diagnosis of giant cell arteritis.

The objective of this study was to describe the perioperative findings during temporal artery biopsy (TAB) and the characteristics associated with a diagnosis of giant cell arteritis (GCA). Perioperative findings were prospectively described by a single operator blinded to the clinical and laboratory characteristics of the patients on 40 consecutive TABs, of which 21 were positive (53%) for GCA. Patients with a TAB positive for GCA (TAB+) more frequently had abnormalities on palpation of the temporal artery than negative TAB (TAB-) patients (mainly pulse abolition (p=0.

Overexpression of IgG2 in patients resembling IgG4-related disease with normal IgG4.

IgG4-Related Disease (IgG4-RD) results from tissue infiltration by IgG4-expressing plasma cells and lymphocytes, leading to fibrosis and organomegaly. Clinical presentation is remarkably variable according to organ involvement, and high IgG4 serum concentration, initially considered a diagnostic hallmark of IgG4-RD, tends to be forgone as an indispensable criterion for its diagnosis; it can indeed be absent in some patients, highlighting the diversity of presentation of this dysimmune condition. Nevertheless, elevation of IgG4 serum concentration in suggestive settings remains an argument in favour of IgG4-RD, and while other IgG subclasses can be elevated, this biological feature lacks any diagnostic value.

Characteristics and Clinical Value of 18F-FDG PET/CT in the Management of Adult-Onset Still's Disease: 35 Cases.

While the diagnosis of adult-onset Still's disease (AOSD) involves the exclusion of differential diagnoses, the characteristics and value of 18F-Fluorodeoxyglucose (18F-FDG) Positron Emission Tomography coupled with CT (PET/CT) in the management of AOSD remain poorly known. Our retrospective study included patients from four centers, fulfilling Yamaguchi or Fautrel criteria, who underwent a PET/CT during an active AOSD. Thirty-five patients were included.
