What is Behcet’s Syndrome? By: Freya Howe


 Behcet’s syndrome (also known as Behcet’s disease) is an Autoinflammatory chronic

illness, resulting in the inflammation of blood vessels and tissues. Behcet’s affects

roughly 10.3 people per 100,000 and is far more common in areas such as the

Middle East, Far East, and the Mediterranean. In countries like Türkiye, Iran, and

Japan. Behcet’s is a poorly understood disease that has debilitating effects on

people's lives, which is why research and advocacy are such important things.

The cause of Behcet’s disease is currently unknown; however, both genetic and

environmental factors seem to contribute. Behcet’s most commonly affects those in

specific ethnic groups, with Türkiye reporting the highest number of cases. However,

a person’s environment also influences their likelihood of developing Behcet’s; those

from an at-risk ethnic group who have moved from their home countries elsewhere

have a lower risk of developing this disease.

Behcet’s presents itself through a variety of symptoms which are shared by

numerous other conditions; this contributes to its difficulty in diagnosing. Patients

experience: oral and genital ulcers, inflamed eyes, blurred vision, headaches, acne-

like spots, and swollen joints. These symptoms are often extremely painful, resulting

in blindness, difficulty eating, arthritis, fatigue, and in rare cases nervous issues.

Patients report feeling lonely and isolated due to managing their illness, often losing

their confidence, income, and close relationships they had.

Behcet’s is a difficult disease to diagnose as there is no single test to identify it.

Doctors may use blood tests, urine tests, or skin biopsies to look for signs of the

condition, or to rule out other causes. Because of the extensive process, patients are

often delayed in diagnosis.

Currently, there is no cure for Behcet’s disease; however, the symptoms can be

managed to improve the affected person's quality of life with medicine that reduces the

inflammation of the affected areas. These include steroids – anti-inflammatory

medicines, immunosuppressants – reducing the activity of the immune system, and

biological therapies – which target the biological processes involved with

inflammation. Treatment options are highly individualized as symptoms and

circumstances vary from person to person.

Current research focuses on finding the most effective biological therapy to manage

Behcet’s disease, as well as gaining high-quality evidence of the effects of these

therapies, to help patients make an informed choice on which treatment to

receive.

It’s important that people understand this condition to advocate for and

empathise with those who are affected by this disease. People with Behcet’s often

experience mental health issues due to their illness; it can impact someone’s job,


relationships, and daily life. Many find it difficult to function properly in their day-to-

day lives, experiencing debilitating pain due to their symptoms. Advocacy for those

with Behcet’s is incredibly important as it brings more awareness to the condition,

letting patients know they’re not alone. More access to resources educating

someone on Behcet’s reduces misconceptions people have about the disease and

allows a person to recognise their symptoms sooner and receive care.

In summary, Behcet’s is a serious and debilitating disease which can completely

reshape a patient’s life; advocacy, education, and more research are essential to

inform people of this condition and ensure those affected receive adequate care.
