Definition

Behçet’s disease is a rare disorder that causes in different parts of the body, including the mouth, eyes, skin, joints, and genitals. The disease is named after Hulusi Behçet, a Turkish dermatologist who first described it in 1937.

Behçet’s disease is characterized by episodes of inflammation that can cause painful ulcers in the mouth and genital area, skin rashes, joint , and eye inflammation that can lead to vision loss. In some cases, the disease can also affect the central nervous system, causing headaches, seizures, and other neurological symptoms.

The exact cause of Behçet’s disease is not known, but it is believed to be a combination of and environmental factors. The disease is more common in people of Mediterranean, Middle Eastern, and Asian descent.

Causes

While the exact cause of the disease is unknown, several factors have been identified as potential triggers of Behçet’s disease:

  1. Genetics: There is evidence that Behçet’s disease is a genetic condition. Studies have found that the disease is more common in people of Middle Eastern, Mediterranean, and East Asian descent, and that it tends to run in families.
  2. Environmental factors: Environmental factors such as infections and exposure to toxins have been linked to Behçet’s disease. Certain and infections, such as Streptococcus and Herpes simplex virus, have been associated with the development of the disease. Exposure to certain toxins, such as pesticides and heavy metals, has also been linked to Behçet’s disease.
  3. Autoimmunity: Behçet’s disease is believed to be an autoimmune disorder, which means that the immune system mistakenly attacks healthy tissues in the body. This results in inflammation and damage to various organs and tissues.
  4. Immunological dysregulation: Immunological dysregulation, which refers to an imbalance in the immune system, has been suggested as a possible cause of Behçet’s disease. Some studies have found that people with the disease have abnormal levels of certain immune cells and cytokines, which are proteins that regulate the immune response.
  5. Hormonal imbalances: Hormonal imbalances have also been linked to the development of Behçet’s disease. Studies have found that women are more likely to develop the disease during their reproductive years, which suggests that hormonal changes may play a role in the disease.

Overall, while the exact cause of Behçet’s disease is not yet fully understood, a combination of genetic, environmental, and immunological factors is believed to contribute to its development. Early and treatment can help manage the symptoms of the disease and prevent complications.

Symptoms

The main symptoms of Behçet’s disease can vary from person to person, but may include the following:

  1. Oral ulcers: Painful, recurrent ulcers that develop on the inside of the mouth, often on the tongue or inside of the cheeks.
  2. Genital ulcers: Painful sores that develop in the genital area, which can make sex and urination uncomfortable.
  3. Skin lesions: Raised, red or purple bumps on the skin that may be painful or itchy.
  4. Eye inflammation: Eye pain, redness, and are common symptoms of Behçet’s disease, and can lead to more serious problems like blindness.
  5. : Joint pain, , and are common symptoms of Behçet’s disease, which can affect any joint in the body.
  6. Gastrointestinal symptoms: , , and may occur in some people with Behçet’s disease.
  7. Central nervous system symptoms: In some cases, Behçet’s disease can cause inflammation in the brain or , leading to headaches, , and other neurological symptoms.

It’s important to note that not all people with Behçet’s disease will experience all of these symptoms, and some may only experience a few. Additionally, the severity of symptoms can vary from to . If you have any of these symptoms, it’s important to talk to your doctor right away. Early diagnosis and treatment can help manage symptoms and prevent serious complications.

Diagnosis

The diagnosis of Behçet’s disease is primarily based on findings, including the presence of recurrent oral and genital ulcers, as well as other symptoms such as skin lesions, joint pain, and eye inflammation. There is no single test that can definitively diagnose Behçet’s disease, and the diagnosis is usually made by a rheumatologist or other specialist who is experienced in managing autoimmune disorders.

The main laboratory tests used to diagnose Behçet’s disease include:

  1. HLA-B51: The presence of HLA-B51 gene is strongly associated with Behçet’s disease. The HLA-B51 gene test is not used to diagnose the disease but can be used to rule out other conditions that mimic Behçet’s disease.
  2. (): A CBC is a routine blood test that measures the number of red blood cells, white blood cells, and platelets in the blood. People with Behçet’s disease may have increased white blood cell counts, , or low platelets.
  3. Erythrocyte sedimentation rate (): ESR is a blood test that measures how quickly red blood cells settle to the bottom of a tube. Higher than normal ESR levels may indicate inflammation in the body.
  4. C-reactive protein (): CRP is a protein produced by the in response to inflammation. A high level of CRP in the blood is an of inflammation in the body.
  5. Antinuclear Antibodies (ANA): ANA are autoantibodies that attack the body’s own cells and tissues. Elevated ANA levels are found in some people with Behçet’s disease.
  6. Skin : A skin biopsy may be performed to confirm the diagnosis of Behçet’s disease if skin lesions are present. The biopsy can help to identify the characteristic pathologic findings of the disease.

The diagnosis of Behçet’s disease typically involves a thorough medical history and physical examination, as well as a number of laboratory tests to rule out other potential causes of the symptoms. These may include blood tests to check for inflammation markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), as well as tests for specific antibodies that may be associated with Behçet’s disease.

In addition to laboratory tests, imaging studies such as X-rays, ultrasounds, and magnetic resonance imaging (MRI) may be performed to evaluate the extent and severity of the inflammation in different parts of the body.

Treatment

The main treatment of Behçet’s disease involves managing the symptoms and preventing complications. The treatment plan is usually tailored to the individual needs and may involve a combination of medication, lifestyle changes, and supportive therapies.

Medications

There are several medications that can be used to treat Behçet’s disease, depending on the severity and type of symptoms. Some of the most common medications used for Behçet’s disease include:

  • Corticosteroids: These are powerful anti-inflammatory drugs that can reduce swelling, pain, and inflammation in the affected areas. They can be taken orally, topically, or injected directly into the affected joint or eye. However, long-term use of corticosteroids can have serious side effects, such as osteoporosis, diabetes, and high blood pressure.
  • Immunomodulators: These drugs work by suppressing the immune system to prevent it from attacking healthy tissues. They can help reduce the frequency and severity of the symptoms and prevent complications such as eye inflammation and neurological problems. Some of the most commonly used immunomodulators for Behçet’s disease include azathioprine, methotrexate, and cyclosporine.
  • Biologics: These are a new class of drugs that target specific molecules in the immune system to prevent inflammation and tissue damage. Biologics can be used in patients who do not respond to other treatments or have severe symptoms. Some of the most commonly used biologics for Behçet’s disease include infliximab, adalimumab, and ustekinumab.

Lifestyle changes

In addition to medication, making certain lifestyle changes can also help manage the symptoms of Behçet’s disease. These include:

  • Avoiding triggers: Certain foods, stress, and sunlight exposure can trigger a flare-up of symptoms in some people with Behçet’s disease. Identifying and avoiding these triggers can help prevent or minimize the symptoms.
  • Eating a healthy diet: A balanced diet that is rich in fruits, vegetables, and whole grains can help boost the immune system and reduce inflammation.
  • Getting enough rest: Fatigue is a common symptom of Behçet’s disease. Getting enough rest and avoiding overexertion can help manage fatigue and improve overall health.

Supportive therapies

There are also several supportive therapies that can help manage the symptoms of Behçet’s disease, including:

  • Eye drops: Lubricating eye drops can help relieve dryness and irritation in the eyes. Steroid eye drops can also be used to reduce inflammation and prevent vision loss.
  • Topical creams: Creams and ointments that contain corticosteroids or immunosuppressants can be applied directly to the affected areas to reduce inflammation and pain.
  • Physical therapy: Physical therapy can help improve joint mobility and reduce pain and stiffness in the affected areas.

In summary, the main treatment of Behçet’s disease involves managing the symptoms with medications, lifestyle changes, and supportive therapies. A comprehensive treatment plan should be tailored to the individual needs of the patient and may involve a combination of different approaches. It is also important to work closely with a healthcare provider to monitor the disease progression and prevent complications.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.
