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.
