• #1 Her Strange Blisters Wouldn’t Go Away. What Was It? – The New York Times

  https://www.nytimes.com/2023/10/07/magazine/pemphigus-vulgaris-diagnosis.html

  An old test for the disease, called the Nikolsky test, was to rub the normal-appearing skin next to the blisters. In pemphigus, that skin often sheers off in thin sheets. […] Now a blood test can help identify the specific antibodies that do the damage. […] As with B.P., Alloo explained to the patient, pemphigus can often be treated with steroids. But when these are not sufficient or cause intolerable side effects, the next step is often a medication called rituximab. […] The patient had her first two doses of rituximab soon after that. Over the next few months her skin began to clear.

• #1 Blistering Diseases

  https://www.clevelandclinicmeded.com/medicalpubs/diseasemanagement/dermatology/blistering-diseases/

  Autoimmune mucocutaneous blistering diseases (AMBDs) are a group of conditions that manifest with blisters on the skin or mucous membranes. […] In order to get the most accurate diagnosis when performing biopsies in AMBD, the tissue for hematoxylin and eosin (HE) should be taken from the edge of a blister and the sample for direct immunofluorescence (DIF) should be taken from perilesional skin. […] Skin biopsies for HE staining and DIF confirm the diagnosis. Histologic findings of a blister show a subepidermal bullae with an inflammatory infiltrate of predominantly eosinophils with neutrophils and histiocytes in the upper dermis. […] Perilesional, uninvolved skin is ideal for DIF. DIF demonstrates fine, linear IgG and C3 at the basement membrane zone. […] Serologic studies for indirect immunofluorescence (IIF) can help to confirm the diagnosis. Circulating IgG antibodies to the basement membrane zone can be detected in approximately 80% of patients with BP.

• #1 Diagnosis of Autoimmune Blistering Diseases

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6224342/

  Autoimmune skin blistering diseases (AIBD) are characterized by autoantibodies that are directed against structural proteins in the skin and adjacent mucous membranes. […] The gold standard for diagnosis of AIBD is the detection of autoantibodies or complement component 3 by direct immunofluorescence (DIF) microscopy of a perilesional biopsy. […] Exact diagnosis is essential for both treatment and prognosis, since some AIBD are associated with malign tumors such as paraneoplastic pemphigus and anti-laminin 332 mucous membrane pemphigoid. […] The diagnosis of AIBDs is based on the combination of the clinical presentation and detection of tissue-bound and/or circulating autoantibodies. […] Tissue-bound autoantibodies can be detected via direct immunofluorescence (DIF) microscopy, which is the diagnostic gold standard for AIBD.

• #1 Bullous Pemphigoid: Causes, Symptoms, and Treatment — DermNet

  https://dermnetnz.org/topics/bullous-pemphigoid

  Bullous pemphigoid is the most common form of autoimmune subepidermal blistering disease. […] Bullous pemphigoid can be a serious disease, particularly when widespread or resistant to treatment. […] When typical bullae are present, the diagnosis is suspected clinically. In most cases, the diagnosis will be confirmed by a skin biopsy of an early blister. […] Pathological examination of bullous pemphigoid shows a split under the epidermis. […] Direct immunofluorescence staining of a skin biopsy taken adjacent to a blister highlights antibodies along the basement membrane that lies between the epidermis and dermis. […] Blood tests include an indirect immunofluorescence test for circulating pemphigoid BP180 antibodies. […] If the pemphigoid is very widespread, hospital admission may be arranged to dress blisters and erosions.

  https://www.clevelandclinicmeded.com/medicalpubs/diseasemanagement/dermatology/blistering-diseases/

  Oral or cutaneous biopsies for HE staining and DIF are needed to confirm the diagnosis. Histopathologic findings of an early vesicle show intraepidermal acantholysis, which is a loss of adhesion between keratinocytes. […] Normal skin adjacent to an early blister is ideal for DIF, which shows intercellular IgG and C3 within the epidermis. […] Biopsies for HE and DIF should be performed to confirm the diagnosis. Histologically, findings are almost identical to BP. A subepidermal vesicle is seen with an inflammatory infiltrate of neutrophils and eosinophils in the upper dermis. […] DIF of perilesional mucosa reveals linear IgG and C3 deposition at the basement membrane zone in 95% of patients.

• #1 Diagnosis of Autoimmune Blistering Diseases

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6224342/

  In dermatitis herpetiformis, DIF microscopy reveals granular deposition of IgA at the dermal papillae and along the DEJ. […] For the identification of the target antigen, three main systems have been described: (i) Enzyme-linked immunosorbent assay (ELISA), (ii) IIF microscopy, and (iii) immunoblot/immunoprecipitation. […] ELISA systems allow the identification and quantification of autoantibodies against specific autoantigens. […] The sensitivity of the BP180 NC16A ELISA ranges between 84 and 89% in BP and between 96 and 97% in pemphigoid gestations. […] In most of the BP patients, autoantibodies are also directed against BP180-epitopes outside the NC16A-domain. […] The major immunoglobulin class in BP is IgG. […] In BP, autoantibodies are directed against a 180 kDa-sized (BP180/BPAG2/XVII collagen) and/or a 230 kDa-sized (BP230/BPAG1) antigen, which are essential for dermal-epidermal adhesion.

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6224342/

  Diagnosis is made by DIF microscopy of a perilesional biopsy, showing linear deposition of IgG and/or IgA and/or C3 along the DEJ. […] The main target antigen in MMP is BP180. […] The diagnosis is based on the DIF and IIF microscopy findings as well as commercial ELISA systems. […] The autoantigen is the epidermal transglutaminase, however antibodies against gliadin, endomysium, tissue transglutaminase (TG2), and epidermal transglutaminase (TG3) can be detected.

  The combination of serology and biopsy increases the sensitivity and specificity of research into autoimmune blister diseases. […] With both pemphigus and pemphigoid, it is necessary to perform additional tests, such as ELISA and immunoblot, in order to be able to determine the antigen involved in more detail. […] All sera with a differential diagnosis of pemphigus or pemphigoid are routinely screened with ELISA to see if antibodies to an autoantigen are indeed present. […] The initial diagnosis in the event of suspected paraneoplastic pemphigus is immunoblot and indirect immunofluorescence on rat bladder. […] If possible, additional tests can be carried out if the results from the above techniques are not clear.

  https://emedicine.medscape.com/article/1062939-overview

  Epidermolysis bullosa (EB) is a group of inherited bullous disorders characterized by blister formation in response to mechanical trauma. […] Discoveries of the molecular basis of epidermolysis bullosa have resulted in the development of diagnostic tools, including prenatal and preimplantation testing. […] Obtain a skin biopsy following a thorough history and physical examination. Routine histologic analysis is useful only for excluding other causes of blistering. When epidermolysis bullosa (EB) is suspected, the best approach is to obtain 2 biopsy specimens. Analyze one specimen using electron microscopy (EM) and the other using immunofluorescent microscopy. […] Routine light microscopy can be used only to exclude other causes of blistering and cannot be used to make the diagnosis of EB.

  Allergy blisters, often resulting from contact dermatitis, are typically treated using topical corticosteroids or oral antihistamines. Avoiding the allergen and applying cold compresses can alleviate discomfort. In severe cases, prescription medication may be necessary. Consult your healthcare provider for personalized treatment options. […] Diagnosing a blister involves a thorough examination of the affected area by a healthcare professional. They may ask about any recent exposure to possible irritants or allergens, your medical history, and the progression of the blister. Further tests may be necessary for a definitive diagnosis. […] If the blister is a symptom of contact dermatitis, specifically allergic contact dermatitis, it can be challenging to identify the exact allergen responsible. Patch testing is frequently used in such cases, where small amounts of potential allergens are applied to the skin using patches, and reactions are observed over a few days.

  Diabetic blisters on feet: diagnosis and management. If you have diabetes and are not able to manage it properly, the risk of developing diabetic blisters on your feet is quite high. However, its not a severe problem. Diabetic blisters heal on their own. However, in some cases, you may need to drain the fluid and remove the dead tissue to prevent its symptoms or infection. To prevent infection, doctors recommend taking antibiotics medications, and proper care of the wound because infection can spread to other parts and can be fatal. So, managing your blister until it heals is important. […] For diagnosis, the doctor examines your foot and looks for the signs of infection such as redness, swelling, warmth, discoloration, or discharge. To get an image of the skin, the doctor may order imaging tests such as X-rays or MRIs. To check for the infection, the doctor takes a sample of the skin and the fluid discharge from the blister to test for infection.
