Recommendations for the diagnosis and treatment of anti-neutrophil cytoplasmic autoantibody associated vasculitis.

Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities.

Tocilizumab in cranial and extracranial giant cell arteritis: a national multicenter study of 471 cases.

Objective: The spectrum of giant cell arteritis (GCA) includes different vascular phenotypes. Tocilizumab (TCZ) is the only biologic currently approved regardless these phenotypes. We aimed to assess the effectiveness of TCZ in different phenotypes.

Effectiveness of janus kinase inhibitors in relapsing giant cell arteritis in real-world clinical practice and review of the literature.

Background: A substantial proportion of patients with giant cell arteritis (GCA) relapse despite standard therapy with glucocorticoids, methotrexate and tocilizumab. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signalling pathway is involved in the pathogenesis of GCA and JAK inhibitors (JAKi) could be a therapeutic alternative. We evaluated the effectiveness of JAKi in relapsing GCA patients in a real-world setting and reviewed available literature.

Scurvy. A forgotten pseudovasculitis.

Scurvy is a nutritional disease caused by ascorbic acid (vitamin C) deficiency. Althought currently it is a rare disease, we should considerer it in the differential diagnosis of purpura and arthritis in patients with restrictive diets. We present the case of a 49-year-old man with a history of a nutritional disorder presented to our hospital with generalized purpura and hemarthros.
