Sarcoidosis

Sarcoidosis is an inflammatory disease that affects multiple organs in the body, but mostly the lungs and lymph glands. In people with sarcoidosis, abnormal masses or nodules (called granulomas) consisting of inflamed tissues form in certain organs of the body. These granulomas may alter the normal structure and possibly the function of the affected organ(s).

What Are the Symptoms of Sarcoidosis?

The symptoms of sarcoidosis can vary greatly, depending on which organs are involved. Most patients initially complain of a persistent dry cough, fatigue, and shortness of breath. Other symptoms may include:

  • Tender reddish bumps or patches on theskin.
  • Red and tearyeyes or blurred vision.
  • Swollen and painful joints.
  • Enlarged and tender lymph glands in the neck, armpits, and groin.
  • Enlarged lymph glands in the chest and around the lungs.
  • Hoarse voice.
  • Pain in the hands, feet, or other bony areas due to the formation of cysts (an abnormal sac-like growth) in bones.
  • Kidney stone
  • Enlarged liver.
  • Development of abnormal or missedheart beats (arrhythmias), inflammation of the covering of the heart (pericarditis), or heart failure.
  • Nervous systemeffects, including hearing loss, meningitis, seizures, or psychiatric disorders (for example, dementia, depression, psychosis).

In some people, symptoms may begin suddenly and/or severely and subside in a short period of time. Others may have no outward symptoms at all even though organs are affected. Still others may have symptoms that appear slowly and subtly, but which last or recur over a long time span.

What Causes Sarcoidosis?

The exact cause of sarcoidosis is not known. It is a type of autoimmune disease associated with an abnormal immune response, but what triggers this response is uncertain. How sarcoidosis spreads from one part of the body to another is still being studied.

How Is Sarcoidosis Treated?

There is no cure for sarcoidosis, but the disease may get better on its own over time. Many people with sarcoidosis have mild symptoms and do not require any treatment. Treatment, when it is needed, is given to reduce symptoms and to maintain the proper working order of the affected organs.

Treatments generally fall into two categories — maintenance of good health practices and drug treatment. Good health practices include:

  • Getting regular check-ups with yourhealth care provider
  • Eating a well-balanced dietwith a variety of fresh fruits and vegetables
  • Drinking enough fluids every day
  • Getting six to eight hours ofsleep each night
  • Exercisingregularly and managing your weight
  • Quittingsmoking

Drug treatments are used to relieve symptoms and reduce the inflammation of the affected tissues. The oral corticosteroid prednisone is the most commonly used treatment. Fatigue and persistent cough are usually improved with steroid treatment. If steroids are prescribed, you should see your doctor at regular intervals so that he or she can monitor the disease and the side effects of treatment. Other treatment options include methotrexate(Otrexup,Rheumatrex), hydroxychloroquine (Plaquenil), and other drugs.
