Final answer:
ANCA-associated vasculitis can affect multiple organ systems in the body, including the kidneys, lungs, and skin. Other less commonly affected organ systems include the nervous system, gastrointestinal tract, and eyes.
Step-by-step explanation:
ANCA-associated vasculitis is an autoimmune disease that can affect multiple organ systems in the body. The most commonly affected organs are the kidneys, lungs, and skin. Inflammation in the blood vessels of these organs can lead to various symptoms and complications. For example, kidney involvement can cause kidney damage and impaired function, while lung involvement can result in respiratory problems such as cough, shortness of breath, and lung nodules. Skin involvement may manifest as rashes or ulcers. Other organ systems, although less commonly affected, can include the nervous system, gastrointestinal tract, and eyes.
