Relapsing polychondritis is a disease characterized by autoimmune-like episodic or progressive inflammation of cartilage and other connective tissue, such as the nose, ears, throat, joints, kidneys, and heart.
Cartilage is a tough, flexible tissue that turns into bone in many places in the body. Bones all start out as cartilage in the fetus. Consequently, children have more cartilage than adults. Cartilage persists in adults in the linings of joints, the ears, the nose, the airway and the ribs near the breast bone. All these sites are attacked by relapsing polychondritis, which usually occurs equally in middle-aged males and females. It is frequently diagnosed along with rheumatoid arthritis, systemic lupus erythematosus, and other connective tissue diseases.
Causes and symptoms
The most common first symptom of relapsing polychondritis is pain and swelling of the external ear. Usually, both ears turn red or purple and are tender to the touch. The swelling can extend into the ear canal and beyond, causing ear infections, hearing loss, balance disturbances with vertigo and vomiting, and eventually a droopy ear. The nose is often afflicted as well and can deteriorate into a flattened nose bridge called saddle nose. Inflammation of the eye occurs less frequently, but can lead to blindness.
As relapsing polychondritis advances, it causes more dangerous symptoms such as deterioration of the cartilage that holds the windpipe open. Progressive disease can destroy the integrity of the airway and compromise breathing. Destruction of the rib cartilage can collapse the chest, again hindering breathing. Joints everywhere are involved in episodes of arthritis, with pain and swelling. Other tissues besides cartilage are also involved, leading to a variety of problems with the skin and other tissues. Occasionally, the aorta or heart valves are damaged.
The disease may occur in episodes with complete remission between, or it may smolder along for years, causing progressive destruction.
A characteristic array of symptoms and physical findings will yield a diagnosis of relapsing polychondritis. Laboratory tests are sometime helpful. Biopsies of the affected cartilage may confirm the diagnosis. Further diagnostic tests are done to confirm other associated conditions such as rheumatoid arthritis. It is important to evaluate the airway, although only 10% of patients will die from airway complications.
Mild inflammations can be treated with aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen. Corticosteroids (most often prednisone) are usually prescribed for more advanced conditions and do improve the disease. They may have to be continued over long periods of time, in which case their usage must be closely watched to avoid complications. Immune suppression with cyclophosphamide, azathioprine, cyclosporine, or dapsone is reserved for more aggressive cases. A collapsed chest or airway may require surgical support, and a heart valve or aorta may need repair or replacing.
Aorta — The biggest artery in the body, receiving blood directly from the heart.
Connective tissue — Several types of tissue that hold the body's parts together-tendons, ligaments, fascia, and cartilage.
Inflammation — The body's immune reaction to presumed foreign substances like germs. Inflammation is characterized by increased blood supply and activation of defense mechanisms. It produces redness, swelling, heat, and pain.
There is no known cure for relapsing polychondritis. It can only be combated with each onset of inflammation and deterioration of cartilaginous tissue. As the disease progresses over a period of years, the mortality rate increases. At five years duration, relapsing polychondritis has a 30% mortality rate.

chronic atrophic polychondritis (polychondritis chro´nica atro´phicans) (relapsing polychondritis) an acquired disease of unknown origin, chiefly involving various cartilages and showing both chronicity and a tendency to recurrence; it is marked by inflammatory and degenerative lesions of various cartilaginous structures.
a degenerative and inflammatory disease of cartilage producing arthritis, collapse of the pinna, the cartilaginous portion of the nose, and the tracheobronchial tree; death may occur from chronic infection or suffocation because of loss of stability in the tracheobronchial tree; of autosomal genetic transmission.
