What treatment may be indicated for vasculitis involving circulating immune complexes?
Antibiotic therapy.
Plasmapheresis.
Enzymatic debridement.
Radiation therapy.
The correct answer is: Plasmapheresis.
Plasmapheresis is particularly indicated for treating vasculitis involving circulating immune complexes because it is a procedure that removes these harmful antibodies and immune complexes from the bloodstream. In cases of vasculitis, there is an inappropriate immune response that can cause inflammation and damage to blood vessels, often leading to various complications. By filtering the blood and separating plasma from its cellular components, plasmapheresis can help alleviate symptoms and provide relief from the effects of the immune complexes that contribute to the condition. In contrast, other treatments such as antibiotic therapy are typically reserved for bacterial infections rather than immune-mediated conditions like vasculitis. Enzymatic debridement is aimed at removing necrotic tissue from wounds and does not directly address the underlying immune process in vasculitis. Radiation therapy is used for various malignancies and inflammatory conditions but is not a recommended treatment for vasculitis related to immune complex deposition. Thus, plasmapheresis stands out as the most relevant option for managing such cases effectively.
