Bullous pemphigoid is an autoimmune disorder. If you have it, your immune system attacks healthy cells in your skin and mouth, causing blisters and sores. No one knows the cause. Bullous pemphigoid does not spread from person to person. It does not appear to be inherited. But some people’s genes put them more at risk for bullous pemphigoid. Bullous pemphigoid is most common in older adults and may be fatal for older, sick patients. Bullous pemphigoid usually occurs in elderly persons and is rare in young people.
Bullous pemphigoid (BUL-us PEM-fih-goid) is a rare skin condition that causes large, fluid-filled blisters. They develop on areas of skin that often flex — such as the lower abdomen, upper thighs or armpits. Bullous pemphigoid is most common in older adults.
Bullous pemphigoid occurs when your immune system attacks a thin layer of tissue below your outer layer of skin. The reason for this abnormal immune response is unknown, although it sometimes can be triggered by taking certain medications.
Bullous pemphigoid often goes away on its own in a few months, but may take as many as five years to resolve. Treatment usually helps heal the blisters and ease any itching. It may include corticosteroid medications, such as prednisone, and other drugs that suppress the immune system. Bullous pemphigoid can be life-threatening, especially for older people who are already in poor health.[rx]
Types of Bullous Pemphigoid:
Bullous pemphigoid comes in two primary forms:
- Classic Bullous Pemphigoid: This is the most common type, where large blisters form on the skin, often on the arms, legs, and abdomen.
- Mucous Membrane Pemphigoid: In this type, blisters and sores affect the mucous membranes inside your body, such as the mouth, eyes, and genitals.
Causes of Bullous Pemphigoid:
The exact cause of bullous pemphigoid is not fully understood, but it’s believed to be related to an autoimmune response. Here are some potential triggers and risk factors:
- Autoimmune Reaction: Your immune system mistakenly attacks the skin’s basement membrane, leading to blister formation.
- Age: Bullous pemphigoid is more common in older adults.
- Medications: Certain drugs, like antibiotics and diuretics, can trigger the condition in some individuals.
- Infections: In rare cases, infections like hepatitis and herpes may play a role.
- Genetics: Some people may have a genetic predisposition to bullous pemphigoid.
- Neurological Disorders: Conditions like Parkinson’s disease may increase the risk.
- UV Exposure: Excessive sun exposure might be a factor in some cases.
- Chemical Exposure: Contact with certain chemicals may trigger the condition.
- Other Autoimmune Diseases: Having other autoimmune disorders can increase your risk.
- Stress: High stress levels could potentially worsen symptoms.
- Smoking: Smoking may be associated with a higher risk.
- Dental Procedures: Dental work has been linked to some cases of mucous membrane pemphigoid.
- Eye Injuries: Eye injuries or surgeries can lead to mucous membrane pemphigoid in the eyes.
- Menopause: Some women develop bullous pemphigoid during menopause.
- Insect Bites: In rare cases, insect bites may trigger the condition.
- Vaccinations: Certain vaccines have been reported to trigger bullous pemphigoid in some individuals.
- Certain Foods: Some people may be sensitive to specific foods.
- Hormonal Changes: Hormonal fluctuations may contribute to the development of this condition.
- Environmental Factors: Exposure to pollutants or irritants might play a role.
