Understanding Pemphigoid

Pemphigoid is a group of rare autoimmune blistering disorders. An autoimmune disorder occurs when the immune system malfunctions and creates antibodies that attack and cause damage to a part of the body. In pemphigoid, the basement membrane below the epidermis is attacked. This results in blisters that form on the skin and mucous membranes. Although pemphigoid can occur at any age and in any race and gender, it occurs more commonly in the elderly. Pemphigoid is similar to pemphigus, another group of rare autoimmune blistering disorders. The blisters in pemphigoid are deeper and less fragile than in pemphigus.

Symptoms of Pemphigoid

Symptoms of pemphigoid, including location and nature of blisters, and treatments depend on the type of pemphigoid. There are several types:

Cicatricial pemphigoid is also known as mucous membrane pemphigoid, as the lesions usually occur on mucous membrane surfaces. The gums are commonly affected,and epithelium of the eye (cornea and conjunctiva) is affected in up to one-third of cases. Cicatricial pemphigoid can result in blindness if it involves the eyes, respiratory compromise if it involves the deeper parts of the throat, and infections if it leaves areas of open skin.

Bullous Pemphigoid is limited to the skin with blisters presenting primarily on the abdomen, groin, back, arms and legs. The blisters may itch and be painful.

Diagnosis of Pemphigoid

Diagnosing pemphigoid can be very difficult and may take months or even years. When the disease is diagnosed early, before it is widespread and severe, it is easier to control and results in fewer complications. Unfortunately, early diagnosis is not typical. A person with pemphigoid may present with a single blister that doesn't heal. They may see several physicians and take several medications that don't work before they get a definitive diagnosis and the right treatments to control the disease so that the blisters may heal and new ones do not form.

Diagnostic testing may include:

  • Skin biopsy with immunofluorescence. The tissue is stained with a dye and is examined under a special microscope to look for the presence of autoantibodies.
  • Blood work to test for the autoantibodies that occur in pemphigoid.

Treatment of Pemphigoid

Treatment of pemphigoid may include steroids, immunosuppressants, IVIG and/or Rituxan®. Steroids are typically initiated in high doses to get the disease under control and then are weaned. If in the weaning process blisters reappear and/or worsen, immunosuppressants are initiated and weaning is reattempted. If this is unsuccessful in controlling the blisters, IVIG and/or Rituxan® will be initiated. In very severe cases, IVIG may be first-line treatment.
