Infection-related vasculitis

Infection-related vasculitis constitutes the most common cause of secondary vasculitis. A great variety of microorganisms can induce directly or indirectly inflammatory vascular damage resulting in vascular occlusion, tissue ischemia, and necrosis. In the developed world hepatitis B and C-related vasculitis remain the most common clinical syndromes, while HIV-associated vasculitis remains a concern in developing countries.
