Evaluating Avacopan in the Treatment of ANCA-Associated Vasculitis: Design, Development and Positioning of Therapy.

Recently, avacopan has been approved for the treatment of ANCA-associated vasculitis (AAV). Avacopan is an inhibitor of the C5a-receptor, which plays an important role in chemotaxis and the amplification loop of inflammation in AAV. In the most recent, international guidelines avacopan is recommended as steroid-sparing agents for the management of AAV.

Clinical manifestations, imaging and treatment of Sjögren's disease: one year in review 2024.

Sjögren's disease is a systemic autoimmune disorder characterised by hyperactivation of B-cells and cytokine production. The condition may evolve from an asymptomatic, indolent course, with glandular involvement, to several extra-glandular systemic manifestations up to lymphoma development. Recent efforts have been undertaken to identify patient phenotypes at risk of developing specific extraglandular manifestations in order to improve patient management.

Ultrasonographic scores and parotid histopathology in Sjögren's disease: challenges in lymphoma identification.

Objectives: The role of major salivary gland ultrasound (SGUS) in evaluating Sjögren's disease (SjD) continues to be debated. This study aims to assess the effectiveness of two SGUS scores (OMERACT and Hocevar et al.) in identifying lymphoma in SjD patients.

Sjögren's disease and systemic lupus erythematosus overlap syndrome as distinct entity at crossroads of two autoimmune disorders: clinical characterisation from two Italian reference centres for both the diseases.

Objectives: To characterise the overlap syndrome between Sjögren's disease (SjD) and systemic lupus erythematosus (SLE).

Methods: Consecutive patients clinically defined as affected by SjD and SLE overlap syndrome (SjD-SLE), belonging to two Italian rheumatology centres were classified following the application of both the SjD and SLE classification criteria. Clinical, functional, ultrasound and histological data were compared with patients suffering from only SjD or SLE.

Arthralgia and Extraintestinal Manifestations in Crohn's Disease Elevate the Risk of IBD-Related Arthritis over Sacroiliitis.

Introduction: Inflammatory bowel disease (IBD) related arthritis is the most prevalent extraintestinal manifestation (EIM) of IBD, ranging between 10 and 39%. Magnetic resonance enterography (MRE) is used to assess small bowel disease involvement in Crohn's disease (CD) and can detect signs of sacroiliitis in up to 23.5% of patients.
