Systemic vasculitides: an overview

The systemic vasculitides are a group of uncommon but serious multisystem autoimmune disorders characterized by blood vessel inflammation. Timely diagnosis and intervention are crucial in preserving organ function and reducing mortality and morbidity.

Nevertheless, disease relapse is common, and individuals with vasculitides accumulate significant risks of infection, cardiovascular disease and malignancy over time compared with the general population, and invariably report poor quality of life. Toxicity from therapeutic agents – especially glucocorticoids – contributes to these complications
