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.

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.

Article Synopsis
  • - The study focused on examining the relationship between primary Sjögren's syndrome (pSS) and cancer, specifically analyzing the clinical, pathological, and immunological aspects of pSS patients who also had cancer, compared to those without cancer.
  • - Out of 165 pSS patients, 55 had cancers, primarily solid neoplasms, with breast and lung cancers being the most common; significantly, many cancers were diagnosed close to or shortly after the pSS diagnosis.
  • - Findings suggest that there may be a connection between breast cancers and pSS, implying that the immune system's behavior in pSS patients could play a role in cancer development or control.

Article Synopsis
  • - The study evaluated malnutrition prevalence in systemic sclerosis (SSc) patients at a referral center from 1985 to 2019, finding that 59.2% were malnourished and 25% had severe malnutrition.
  • - Malnutrition correlated with disease features, specifically cardiac involvement and limited mouth opening (interincisal distance <35 mm), indicating potential warning signs.
  • - The findings suggest that addressing malnutrition could be crucial for improving health outcomes in SSc patients, given its high prevalence and associations with serious disease symptoms.

Objectives: This study aimed to estimate the prevalence of ANCA-associated vasculitis (AAV). That is, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA), in Southern France in 2018, and evaluate differences among Europeans and non-Europeans.

Methods: This population-based, cross-sectional study used four sources (hospitals, community-based physicians, laboratories, National Health Insurance) to identify adults ≥15 years diagnosed with GPA, MPA or EGPA, living in Hérault and Gard in 2018.

Article Synopsis
  • Subcutaneous tissue involvement in idiopathic inflammatory myopathies (IIM) is not well understood, prompting a systematic review of related conditions like panniculitis and lipodystrophy in both juveniles and adults.
  • The findings indicate that panniculitis is more common in adults, responds well to steroid treatment, and often aligns with the progression of myositis; in contrast, lipodystrophy is mainly found in juveniles and linked to dermatomyositis.
  • The study concludes that lipodystrophy's relationship with myositis diagnosis and potential poor disease control suggests a need for more extensive research to identify risk factors and therapeutic targets in these patients.

  • Anterior atlanto-axial subluxation (AAS) is a condition that can develop in rheumatoid arthritis (RA) patients and can lead to severe neurological problems; this study aimed to find the prevalence and predictors of AAS after 12 years in early polyarthritis patients.
  • The research followed 323 patients enrolled in the ESPOIR cohort, finding that only 4.6% had AAS, with specific factors like IgA RFs at baseline and CRP/RFs after 10 years being associated with the condition.
  • Despite some associations found, the rarity of severe AAS cases suggests that these findings may not have significant clinical importance for predicting the condition's occurrence.

Primary Sjögren's syndrome (pSS) is an autoimmune disease with frequent neurological involvement. Memory complaints are common, but their precise patterns remain unclear. We wanted to characterize patterns of neurocognitive profiles in pSS patients with cognitive complaints.

Objective: To investigate whether antineutrophil cytoplasm antibody (ANCA)-negative and myeloperoxidase (MPO)-ANCA-positive granulomatosis with polyangiitis (GPA) differ from proteinase-3 (PR3)-ANCA-positive GPA.

Methods: Diagnostic characteristics and outcomes of newly diagnosed French Vasculitis Study Group Registry patients with ANCA-negative, MPO-ANCA-positive or PR3-ANCA-positive GPA satisfying American College of Rheumatology criteria and/or Chapel Hill Conference Consensus Nomenclature were compared.

Results: Among 727 GPA, 62 (8.

Objectives: Noonan syndrome is a rare genetic disorder characterized mainly by congenital heart disease, occasional intellectual disability, and varied orthopaedic, rheumatological and haematologic anomalies. Despite potentially serious functional consequences, joint involvement has been rarely studied in the literature. Our objective was to perform a retrospective study evaluating the prevalence and characteristics of joint involvement in Noonan syndrome.

Objective: To show different approaches for sexual-sparing robot assisted radical cystectomy in women.

Materials And Methods: Radical cystectomy (RC) is a mainstay treatment for localized muscle invasive bladder cancer and high-risk non muscle invasive bladder cancer not responding to adequate endovesical therapy. In women traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall, but this technique often brings sexual disorders.

Objectives: Measures on conventional radiography are used to detect, especially in rheumatoid arthritis, upper cervical spine instabilities (CSIs) with the anterior and posterior atlanto-dental intervals (AADI and PADI) measurements. Our objective was to evaluate the diagnostic performance and reliability of AADIs and PADIs extrapolated based on ratios in assessing anterior atlanto-axial subluxation (aAAS) when plain radiographs do not allow the measures.

Methods: Radiographies of 119 patients were randomly selected.

Objective: To describe the characteristics and long-term outcomes of patients with granulomatosis with polyangiitis (GPA) from the French Vasculitis Study Group database.

Methods: Patients' clinical and laboratory characteristics, Birmingham Vasculitis Activity Score (BVAS)-assessed disease activity, malignancies, opportunistic infections, and vital status were collected at diagnosis and each visit. Estimated probabilities and predictors of overall (OS) and relapse-free survival (RFS) were analyzed by Cox regression.

Objective: Adult-onset Still's disease (AOSD) is a rare inflammatory disease that may be life-threatening if complicated by cardiac problems. We performed a retrospective multicenter study to describe the manifestations, treatments and outcomes of cardiac involvement in AOSD.

Methods: We reviewed the medical databases of eight centers.

Objective: To describe characteristics and long-term outcomes of patients with microscopic polyangiitis (MPA), an antineutrophil cytoplasm antibody (ANCA)-associated small-vessel necrotizing vasculitis.

Methods: MPA patients from the French Vasculitis Study Group Registry satisfying the European Medicines Agency algorithm were analyzed retrospectively. Characteristics at diagnosis, treatments, relapses and deaths were analyzed to identify factors predictive of death or relapse.

Cancer among patients with systemic sclerosis (SSc) would appear to be more prevalent than in the general population. Pathophysiological hypotheses are multiple, involving intertwined factors such as immune system antitumoral response, oxygen species dysregulation, and immunosuppressive treatments. We aimed to identify SSc patients with cancer monitored at our center, describing their clinical and immunological characteristics, such as cancer-specific outcomes.

Skin fibrosis is the hallmark of systemic sclerosis (SSc) a rare intractable disease with unmet medical need. We previously reported the anti-fibrotic potential of mesenchymal stem cells (MSCs) in a murine model of SSc. This model, based on daily intra-dermal injections of hypochlorite (HOCl) during 6 weeks, is an inducible model of the disease.

Glomerulonephritis is a severe complication of microscopic polyangiitis (MPA), a small-vessel vasculitis associated with anti-myeloperoxidase antibodies (MPO-ANCA). We previously showed the pathogenic effects of MPO-ANCA that activate MPO to trigger an oxidative burst mainly through HOCl production, contributing to endothelial injury and lung fibrosis. The aim of this study was to investigate the relationship between MPO-induced oxidative stress, anti-oxidant defenses and renal histological lesions in MPA patients.
