	Polyarteritis nodosa - Wikipedia, the free encyclopedia
		Polyarteritis nodosa (or periarteritis nodosa) is a serious blood vessel disease.
		Polyarteritis nodosa is a disease of unknown cause that affects arteries, the blood vessels that carry oxygenated blood to organs and tissues.
		Polyarteritis nodosa is more common in people with hepatitis B infection.

	THE MERCK MANUAL, Sec. 5, Ch. 50, Diffuse Connective Tissue Disease
		Arterial lesions similar to those in spontaneously occurring polyarteritis nodosa occur in hyperimmunized human volunteers, in animals with experimental serum sickness, and in patients developing hypersensitivity reactions.
		Of patients with massive hepatic infarction, 50% have polyarteritis nodosa, although this complication is rare.
		Polyarteritis nodosa is a possible diagnosis when unexplained fever, abdominal pain, renal failure, or hypertension occurs or when a patient with nephritis or a cardiac disorder has unexplained symptoms such as arthralgia, muscle tenderness or weakness, subcutaneous nodules, purpuric skin rashes, pain in the abdomen or extremities, or rapidly developing hypertension.

	Johns Hopkins Vasculitis Center Discusses Polyarteritis Nodosa, a Type of Vasculitis
		Polyarteritis nodosa is sometimes termed “systemic necrotizing vasculitis”, but this term is non-specific as other forms of vasculitis also have systemic and necrotizing features.
		Polyarteritis nodosa is a small– and medium–sized arteritis affecting multiple organs, especially the skin, peripheral nerve, gut, kidney, and heart.
		Evidence includes the observation that patients with polyarteritis nodosa associated with hepatitis B or hepatitis C have immune complexes consisting of immunoglobulin and viral antigens circulating in the blood and deposited in inflamed vessels.

	Polyarteritis Nodosa Causes, Symptoms, Diagnosis, and Treatment by MedicineNet.com
		Polyarteritis nodosa is a rare autoimmune disease (immune system attacking its own body) featuring spontaneous inflammation of the arteries (arteritis).
		Polyarteritis is not felt to be an inherited condition.
		The diagnosis of polyarteritis nodosa is confirmed by a biopsy of involved tissue that reveals the inflamed blood vessels (vasculitis).

		Polyarteritis nodosa is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
		This means that Polyarteritis nodosa, or a subtype of Polyarteritis nodosa, affects less than 200,000 people in the US population.
		With a diagnosis of Polyarteritis nodosa, it is also important to consider whether there is an underlying condition causing Polyarteritis nodosa.

	Polyarteritis Nodosa
		Classic polyarteritis nodosa is a systemic vasculitis that involves medium-sized muscular arteries in multiple organ systems.[1,2] The kidneys are the most frequently involved, followed by the liver, heart, gastrointestinal tract, musculoskeletal system, and central nervous system.
		Benign cutaneous polyarteritis nodosa is a disease that is limited to the skin, muscles, and joints.[3] The cutaneous lesions are indistinguishable from those of classic polyarteritis nodosa.
		In hepatitis B virus-associated polyarteritis nodosa, glucocorticoids should be started initially to control the most severe life threatening manifestations of polyarteritis nodosa and then rapidly withdrawn.

		Polyarteritis nodosa (PAN) is a specific form of the autoimmune disease known as vasculitis, which involves inflammation of the blood vessels.
		In polyarteritis nodosa inflammation occurs in the medium sized arteries, impairing blood flow through the vessels and to the surrounding tissues.
		In polyarteritis nodosa the immune system produces antibodies that attack the body, causing inflammation to develop in the blood vessels.

	Polyarteritis Nodosa
		Polyarteritis nodosa causes sections of the middle and outer layers of a blood vessel to swell and become inflamed.
		Polyarteritis nodosa may be similar to hypersensitivity angitis, Churg-Strauss syndrome, Cogan's syndrome, Kawasaki's disease and complications associated with methamphetamine addiction, hepatitis B and C infections and other liver conditions.
		The condition may also be suspected if a patient with nephritis or a heart condition has unexplained joint pain, muscle tenderness or weakness, nodes beneath the skin, purplish skin rashes, pain in the stomach, hands or feet or high blood pressure that develops suddenly.

		Classic polyarteritis nodosa (PAN) is a multisystem, necrotizing vasculitis of small and medium-sized muscular arteries in which involvement of the renal and visceral arteries is characteristic.
		PAN does not involve pulmonary arteries, although bronchial vessels may be involved; granulomas, significant eosinophilia, and an allergic diathesis are not part of the classic syndrome.
		In addition, long-term remissions have been reported in PAN associated with hepatitis B virus antigenemia using the antiviral agent.

	Statistics about Polyarteritis nodosa - WrongDiagnosis.com
		The term 'prevalence' of Polyarteritis nodosa usually refers to the estimated population of people who are managing Polyarteritis nodosa at any given time.
		The term 'incidence' of Polyarteritis nodosa refers to the annual diagnosis rate, or the number of new cases of Polyarteritis nodosa diagnosed each year.
		Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
