Permanent morbidity due to PAN is relatively rare, although patients may develop peripheral neuropathy, renal insufficiency or renal failure, and/or hypertension. Fever, weight loss, and malaise are present in 50% of patients; renal failure and hypertension, in 60%; arthritis, arthralgia, and myalgia, in 64%; and peripheral neuropathy and mononeuritis multiplex, in 51%.
