Behcet Disease

(Adamantiales-Behcet Syndrome)

Pronounced: Buh-settes

Definition

Behcet disease is a rare, long-term disorder. Blood vessels are inflamed throughout the body. It causes ulcers in the mouth and genitals, and inflammation in the eyes. Treatment improves outcomes.

Causes

The cause of Behcet disease is unknown. The body’s immune system may be too active. When this happens, healthy tissue is attacked. It may be due to genes or a reaction to an infection.

Risk Factors

Behcet disease is more common in men from the Middle East and Mediterranean. It is also more common people aged 20 to 39 years old. Other things that raise the risk are:

  • A family history of Behcet disease
  • Having a certain gene

Symptoms

Symptoms vary from mild to very serious. They also tend to come and go over months or years. The most common are:

  • Sores in the mouth:
  • Ulcerated Gums

  • Skin problems such as sores that:
    • May appear as red, raised sores or bumps, or may be flat

  • Digestive problems:
    • Causes ulcers and inflammation of the digestive tract—rare

These problems need medical care right away.

Diagnosis

Diagnosing Behcet disease is difficult. Symptoms appear slowly, over months or years. They are similar to symptoms of many other diseases.

There are no specific tests to diagnose Behcet disease. It may be suspected based on:

Mouth sores at least 3 times within a year and at least 2 of these:

  • Eye inflammation
  • Genital sores
  • Skin sores

A pathergy skin test may be used. The skin is pricked with a small needle. If a bump develops at the site of the skin prick, it could mean Behcet disease. However, many people with the disease do not have a reaction to the skin prick.

Treatment

For some people, the illness may go away on its own. If care is needed, it focuses on treating problems to prevent serious complications. With proper care, Behcet disease can be managed.

Treatment options may be:

  • Creams, lotions, and mouth rinses—to help ease swelling and pain
  • Other medicines taken by mouth to:
    • Ease swelling and pain
    • Change how the immune system responds
  • Lifestyle changes such as:
    • Resting when symptoms flare
    • Exercising to keep joints flexible and strong

Prevention

There are no guidelines to prevent Behcet disease.
