What are the 80 autoimmune disorders?
While it’s still too early to draw conclusions, evidence is emerging of links between autoimmune disorders and the virus that causes COVID-19. As a bioinformatics researcher with medical training and expertise in immune system modeling, I find this ...
Should autoimmune diseases always respond to corticosteroids?
Neuronal antibodies are sometimes, but not always, pathogenic. Autoimmune LE may respond to corticosteroids, intravenous IgG (IVIG) or plasma exchange. The cornerstone of paraneoplastic LE therapy is resection of the tumour and/or oncological treatment. Several differential diagnoses must be excluded, among them herpes simplex encephalitis.
Who is at risk for autoimmune disease?
patients with autoimmune disease could be carrying susceptible genes and have several triggers present in the environment that promotes a full-blown condition,” Vista said. There are also certain risk factors that increase the chances of developing ...
Could you be suffering from an autoimmune disease?
Your first symptoms of an autoimmune disease may be general, such as fatigue, low-grade fever, and difficulty concentrating, making autoimmune diseases difficult to diagnose at first. You also may feel depressed and consult a doctor for that.

What autoimmune disease affects the skin?
There are several common autoimmune diseases that affect the skin. These include vitiligo, scleroderma, lupus, psoriasis and vasculitis.
What would cause random blisters on skin?
The most common causes are friction, freezing, burning, infection, and chemical burns. Blisters are also a symptom of some diseases. The blister bubble is formed from the epidermis, the uppermost layer of skin. Its purpose is to protect and cushion the layers below.
What does bullous pemphigoid look like?
Check if you have bullous pemphigoid It usually starts as sore, itchy patches. On white skin the patches look red or pink. On brown and black skin they may look dark reddish-brown. It can affect large areas of the body or limbs.
What does autoimmune rash look like?
Autoimmune rashes can look like scaly red patches, purplish bumps, or more. The appearance of autoimmune rashes will be different, depending on which autoimmune condition is triggering the skin rash. For example, cutaneous lupus may cause a scaly red patch that does not hurt or itch.
What does scleroderma rash look like?
Affected skin can become lighter or darker in color and may look shiny because of the tightness. Some people also experience small red spots, called telangiectasia, on their hands and face. Calcium deposits can form under the skin, particularly at the fingertips, causing bumps that can be seen on X-rays.
What disease causes blisters on hands and feet?
Palmoplantar pustulosis is an autoimmune disorder marked by the appearance of fluid-filled pustules or blisters on the hands and feet. Autoimmune disorders cause the immune system to attack healthy cells. In the case of palmoplantar pustulosis, the immune system attacks the healthy skin on the hands and feet.
What virus causes fluid filled blisters?
Fluid-filled blisters can come from many causes. Chickenpox, shingles, genital herpes, and cold sores are caused by viruses. Rhus dermatitis comes from an oil in plants like poison ivy. Dyshidrotic eczema likely comes from impaired immune function.

What is the underlying cause of bullous pemphigoid?
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.
Function
- The skin is the largest organ of the body. In addition to serving as a protective barrier, the skin is involved in many additional functions of the body such as regulating internal body temperature. Five distinct layers make up the skin; each layer is filled with specialized cells. The two main structural layers of the skin are the epidermis the outermost, protective layer of skin and the dermis an underlying layer that contains numerous specialized cells, t…
Signs and symptoms
- In some autoimmune blistering diseases, blisters or lesions can also form on the mucous membranes, the thin, moist coverings of many of the bodys internal surfaces. Mucous membranes line the esophagus and anus, the inside of the mouth, the nasal passageways, the genitals and the throat. Associated symptoms depend on the location of blister formation, but can include gastrointestinal bleeding, difficulty swallowing or difficulty breathin…
Classification
- The term pemphigus is a general term for a group of related autoimmune blistering diseases. The two main types of pemphigus are pemphigus vulgaris and pemphigus foliaceus. Each type has additional subtypes. Additional disorders are sometimes classified as subtypes of pemphigus including paraneoplastic pemphigus and pemphigus IgA. Some physicians co...
Symptoms
- Pemphigoid gestationis occurs in women during pregnancy or shortly after birth (postpartum period). Affected individuals develop reddish bumps or hives usually around the navel (umbilicus) and the arms and legs. The rash may spread to affect other areas of the body and may be extremely itchy. Eventually, the skin lesions progress to form blisters. Pemphigoid gestationis usually resolves within three months without treatment (spontaneously).
Terminology
- Autoimmune blistering diseases occur when the bodys immune system mistakenly attacks healthy tissue. The immune system normally produces specialized proteins called antibodies. Antibodies react against foreign materials (e.g., bacteria, virus, toxins) in the body bringing about their destruction. Antibodies can directly kill microorganisms or coat them so they are more easily destroyed by white blood cells. Specific antibodies are cre…
Pathophysiology
- In autoimmune blistering diseases, autoantibodies attack proteins that are essential to the proper function of the basement membrane zone, a network of proteins that acts as a glue that holds the epidermis to the underlying tissues of the dermis. In autoimmune blistering disease, the connection (adhesion) of the epidermis and dermis is damaged because autoantibodies attack specific structures or proteins, causing the epidermis and dermis to se…
Mechanism
- In pemphigoid, autoantibodies react against proteins found at the junction where the epidermis and dermis meet, known as the dermal-epidermal junction (DEJ). The DEJ is part of the basement membrane zone.
Clinical significance
- In epidermolysis bullosa acquista, autoantibodies react to collagen VII, a protein that is essential in anchoring the basement membrane to the dermis.
Causes
- The exact, underlying reason why the immune system malfunctions in individuals with autoimmune blistering diseases is unknown. A variety of factors have been speculated to trigger or worsen autoimmune blistering diseases. Such factors include exposure to ultraviolent light, exposure to certain pesticides, hormones, several infectious agents, and certain foods. Certain drugs are also known to play a role in the development or aggravati…
Epidemiology
- Autoimmune blistering diseases affect men and women in equal numbers. Most forms occur in middle-aged individuals, usually people in their 50s and 60s. However, autoimmune blistering diseases can affect individuals of any age including children. The overall incidence and prevalence of pemphigus varies depending upon the specific population studied. Pemphigus is estimated to affect anywhere from 0.7-5 people per 1,000,000 per year in the g…
Diagnosis
- Symptoms of the following disorders can be similar to those of autoimmune blistering diseases. Comparisons may be useful for a differential diagnosis. A diagnosis of an autoimmune blistering disease is suspected based upon identification of characteristic findings, a thorough clinical evaluation, and a detailed patient history. A diagnosis may be confirmed based upon a variety of specialized tests including blood tests or skin biopsy. Bloo…
Overview
- Genetic blistering disease is a group of rare disorders that are characterized by blistering lesions that primarily affect the skin and mucous membranes. These disorders are caused by a mutation to a gene that creates proteins necessary for the proper health and function of the skin. This group of disorders includes Hailey-Hailey disease and the various forms of epidermolysis bullosa. (For more information on this disorder, choose the specific diso…
Risks
- Additional skin disorders can cause blisters including erythema multiforme, porphyria cutanea tarda, staphylococcal scalded skin syndrome, and impetigo. (For more information on this disorder, choose the specific disorder name as your search term in the Rare Disease Database.)
Treatment
- Treatment The treatment of autoimmune blistering diseases is directed toward the specific symptoms that are apparent in each individual and preventing complications potentially associated with these diseases. Although there is no cure for these disorders, they can be controlled medically. Generally, the less widespread an autoimmune blistering disease is, the easier it is to control. The mainstay of treatment for autoimmune blisterin…
Research
- Research is ongoing to learn more about the underlying causes of autoimmune diseases and why these diseases target some people, but not others. Research is also ongoing into the mechanisms that underlie the development of these diseases and into new therapies.
