Slavic populations, such as those in Poland, are considered to have a low prevalence of giant cell arteritis (GCA), although epidemiological data are sparse. The study aimed to compare the reported frequency of GCA in various regions of Poland and analyze the differences between them. We conducted a multicenter, retrospective study of all GCA patients included in the POLVAS registry-the first large multicenter database of patients with vasculitis in Poland.

The co-existence of AAV with different immune-mediated diseases (autoimmune disesases - AID) might affect the clinical presentation of the primary disease. The purpose of the study was to assess the co-existence of AAV with AID and to investigate whether it affects the characteristics and the course of AAV.

- The study aimed to analyze patients with eosinophilic granulomatosis with polyangiitis (EGPA) from the POLVAS registry based on their ANCA status and when they were diagnosed, and compare them to patients with granulomatosis with polyangiitis (GPA) who have elevated eosinophil levels.
- The results indicated that while ANCA-positive and ANCA-negative EGPA patients had similar clinical characteristics, ANCA-negative patients experienced more cardiovascular issues. Moreover, patients diagnosed before 2012 were generally younger and exhibited higher eosinophil counts and more frequent ENT and cardiovascular symptoms.
- The researchers developed a model to differentiate between EGPA and GPA with elevated eosinophils, achieving high
Rat bite fever (RBF) is a rare infectious zoonotic disease caused by two bacterial species: the Gram-negative rod Streptobacillus moniliformis and the Gram-negative coiled rod Spirillum minus. The association between RBF and skin vasculitis and arthritis has been observed. The aim of this paper was to present a case of rat-bite fever with symptoms of skin vasculitis and arthritis, associated with high titers of ANCA antibodies and anti-endothelial cell antibodies suggestive of primary vasculitis.

Smoking is a potential trigger for such diseases, however, its link with AAV remains controversial.
Objectives: The aim of this study was to analyze the link between AAV and smoking based on clinical characteristics, disease activity, and mortality.
