1. Health


Vasculitis is a condition associated with inflammation of blood vessels. While there are several types, vasculitis may occur as a primary condition or secondary to another rheumatic disease.

Vasculitis - What You Need to Know
Vasculitis, an inflammatory condition, can affect any of the body's blood vessels.

What Is Polyarteritis Nodosa?
Polyateritis nodosa is an autoimmune condition that involves spontaneous inflammation of the arteries in the body.

A brief explanation and fast facts about vasculitis.

Necrotizing Vasculitis: What is Necrotizing Vasculitis?
Necrotizing vasculitis is an inflammatory condition of blood vessels characterized by tissue death, scarring, and proliferation of the walls of the blood vessels, which may result in blockage of the vessel. It may occur in rheumatoid arthritis and is commonly seen with systemic lupus erythematosus, polyarteritis nodosa, and systemic sclerosis.

Necrotizing Vasculitis: Symptoms & Diagnosis
Symptoms of necrotizing vasculitis vary depending on the location of the affected vessels. Exam findings may vary depending on the part of the body affected by the necrotizing vasculitis. Neurologic examination may show single or multiple neuropathy (nerve damage).

Necrotizing Vasculitis: Treatment Options
Treatment aims at reduction of the inflammation, allowing the natural healing process to occur. Corticosteroids (given in low doses) or other immunosuppressive drugs may reduce inflammation of the blood vessels

Allergic vasculitis
Allergic vasculitis is hypersensitivity to a drug or foreign agent that leads to inflammation and damage to blood vessels of the skin. (Photos)

Vasculitis - Lower Extremity - (Photo-Picture)
Vasculitis may be caused when antibodies that have attached to antigens in the blood, attach to the blood vessel walls. These purplish spots can be felt in the skin. They do not turn white (blanch) when pressed. As the condition progresses, they may become larger and more bruise-like (ecchymotic), and some may develop central ulceration or necrosis (tissue death).

Vasculitis on the Palm (Photo-Picture)
These spots of blood under the skin (purpura) are caused by vasculitis. The do not turn white with pressure (non-blanchable). In this particular case, the purpura are associated with an underlying disorder affecting the structure of the blood vessel walls (collagen-vascular disorder).

Vasculitis - Urticarial on the Hand - (Photo-Picture)
These red (erythematous), hive-like (urticarial) spots (plaques) are caused by inflammation of the blood vessels (urticarial vasculitis) and do not change over a 24-hour period. The may or my not turn white (blanch) with pressure.

Rapidly progressive glomerulonephritis
Rapidly progressive glomerulonephritis includes any type of glomerulonephritis in which progressive loss of kidney function occurs over weeks to months. Many conditions are known to cause or increase the risk for development of this syndrome, including vascular (blood vessel) diseases such as vasculitis or polyarteritis, lupus nephritis and Henoch-Schonlein purpura.

The Circulatory System
Blood used by the body is brought back to the heart and lungs by the veins of the body. Once the blood has gathered more oxygen from the lungs, it is pumped back out to the body through the arteries.

Polymyalgia Rheumatica and Giant Cell Arteritis
Vasculitis includes polymyalgia rheumatica and giant cell arteritis.

Vasculitic Disorders of Connective Tissue
Vasculitic disorders develop from inflammation of the blood vessels (vasculitis). Vasculitis commonly occurs in disorders that affect connective tissue, but it can also occur in conditions that do not affect connective tissue. Vasculitis is not a disease but rather a disease process, from Merck Manual.
