Immune Globulin Therapy Immune Globulin Therapy Policy Number: Original Effective Date: MM.04.015 05/21/1999 Line(s) of Business: Current Effective Date: HMO; PPO; QUEST 02/01/2013 Section: Prescription Drugs Place(s) of Service: Outpatient I. Description Intravenous immune globulin (IVIG) is a sterile, highly purified preparation of unmodified immunoglobulins, which are isolated from large pools of human plasma. IVIG is an infusion used to treat patients with inherited or acquired immune deficiencies. It provides passive immunity against infection by increasing a person’s antibody titer and antigen-antibody reaction potential. IVIG supplies a broad spectrum of IgG antibodies against bacterial, viral, parasitic, and mycoplasmal antigens. Subcutaneous immune globulin (Sub-q IG) is FDA approved for the treatment of patients with primary immune deficiency. It is injected under the skin using an infusion pump, which means patients can self-administer the product in a home setting. II. Criteria/Guidelines A. IVIG therapy is covered (subject to Limitations/Exclusions and Administrative Guidelines) for the following indications: 1. Treatment of primary immunodeficiencies, including: a. Congenital agammaglobulinemia ( X-linked agammaglobulinemia) b. Hypogammaglobulinemia c. Common variable immunodeficiency d. X-linked immunodeficiency with hyperimmunoglobulin M e. Severe combined immunodeficiency f. Wiskott-Aldrich syndrome 2. Idiopathic thrombocytopenic purpura (ITP) Immune Globulin Therapy 2 3.

These authors have equally contributed to the manuscript. y Received: 7 September 2020; Accepted: 8 October 2020; Published: 10 October 2020 Abstract: Bullous pemphigoid (BP) is the most frequent autoimmune subepidermal blistering disease provoked by autoantibodies directed against two hemidesmosomal proteins: BP180 and BP230. Its pathogenesis depends on the interaction between predisposing factors, such as human leukocyte antigen (HLA) genes, comorbidities, aging, and trigger factors. Several trigger factors, such as drugs, thermal or electrical burns, surgical procedures, trauma, ultraviolet irradiation, radiotherapy, chemical preparations, transplants, and infections may induce or exacerbate BP disease. Identification of predisposing and trigger factors can increase the understanding of BP pathogenesis. Furthermore, an accurate anamnesis focused on the recognition of a possible trigger factor can improve prognosis by promptly removing it. Keywords: bullous pemphigoid; autoimmune bullous disease; trigger factors; predisposing factors; etiopathogenesis 1. Introduction Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disease, affecting predominantly elderly people. It is characterized by generalized pruritic urticarial plaques and tense subepithelial blisters. BP autoantibodies are directed mainly against two hemidesmosomal proteins, BP180 (also termed type XVII collagen) and BP230, which are components of the dermo-epidermal junction (DEJ) [1].

    Bullous Pemphigoid/Pemphigus and administration of the Pfizer/BioNTech vaccine (Comirnaty®). Introduction The Pfizer/BioNTech vaccine (Comirnaty®) is a COVID-19-mRNA-vaccine (nucleoside modified). It is indicated for active immunisation to prevent COVID-19 caused by SARS-CoV-2 virus, in individuals 16 years of age and older. [1] The nucleoside-modified messenger RNA in Comirnaty® is formulated in lipid nanoparticles, which enable delivery of the nonreplicating RNA into host cells to direct transient expression of the SARS-CoV-2 S antigen. The mRNA codes for membrane-anchored, full-length Spike glycoprotein with two point mutations within the central helix. [1] Comirnaty® has been registered in Europe since December 21st, 2020. Bullous skin diseases are a group of dermatoses characterized by blisters and bullae in the skin and mucous membranes. The most common are pemphigus and bullous pemphigoid (BP). Pemphigus and bullous pemphigoid are autoantibody-mediated blistering skin diseases. In pemphigus, keratinocytes in epidermis and mucous membranes lose cell-cell adhesion, and in pemphigoid, the basal keratinocytes lose adhesion to the basement membrane. Bullous pemphigoid is a more common disease than pemphigus [2]. Bullous pemphigoid is the most common heterogeneous subepidermal autoimmune blistering disease (incidence 7 per million person year) [3,4], with an increasing prevalence after the age of 70, although it can also occur in the younger. It is characterized by auto-antibodies against different structural proteins of the hemidesmosomes in the epidermal basement membrane zone (EBMZ). Bullous pemphigoid typically causes severe pruritus with predominantly cutaneous lesions consisting of tense (fluid filled) bullae, erythema, and urticarial plaques.

The body’s immune system is confused Band makes an antibody (type of protein used to fight Blisters Erosions Increased pigmentation infection) that targets a part of the skin that normally (bullae) (broken blisters) holds it together. The attack on the skin causes blisters (firm, fluid-filled bubbles on the skin) to form. This disease most often involves only the skin, but the eyes, mouth, and genitals also can be affected. In most cases, the disease develops on its own, but certain medications also can cause bullous pemphigoid to develop. Bullous pemphigoid commonly affects people older than 60 years but can occur in younger people. Once someone is diagnosed as having this disease, they can have it for many years. Treatment helps to control the disease, but there is no permanent cure. SYMPTOMS Hivelike rash Redness Severe itching and blisters occur in almost all patients. Erosions Early in the course of the disease, some patients may not have blisters but instead have only a rash that looks similar to hives. These hivelike spots can be all over the body; Blisters many times, when blisters appear, they will appear on top of this rash. Blisters will sometimes break, and the exposed skin can be raw and painful. Scars usually do not develop, and the skin can return to normal, although darker spots may remain after the blisters go away.

Tr io Health Meet Pemphigus Warrior LISA What is PEMPHIGUS AND PEMPHIGOID? Overview Pemphigus and pemphigoid are rare autoimmune blistering diseases of the skin and/or mucous membranes. There is currently no cure for either, only remission. Pemphigus is used specifically to describe blistering disorders caused by autoantibodies that recognize components of the epidermis (for instance cellular desmoglein 1 and desmoglein 3). This in turn leads to disruption of the intercellular junctions and loss of integrity (leading to bullae formation). Epidermis Dermis Pemphigoid is a group of subepidermal, blistering autoimmune diseases that primarily affect the skin, especially in the lower abdomen, groin, and flexor surfaces of the extremities. Here, autoantibodies (anti-BPA-2 and anti-BPA-1) are directed against the basal layer of the epidermis and mucosa. A person’s immune system makes antibodies to attack viruses and harmful bacteria. In the context of pemphigus and pemphigoid, however, the immune system is over-active and antibodies instead attack healthy cells in the skin or mucous membranes. As a result, Lisa I was a fulltime professional photographer and marketing consultant who realized one day that it took almost The biggest challenge now, beyond the mental knowledge of how serious this disease is, would be tracking • Skin cells separate from each other • Fluid collects between skin layers • Blisters form and may cover a large area of skin 3 days to recover from a 10-hour wedding event—every week.

J.Cruces Departmentof Dermatology, Complexo Hospitalario de P ontevedra,C /LuoreiroCrespo 2, E-36200,P ontevedra,Spain. E-mail:[email protected] AcceptedOctober 19, 2001. Sir, Severalcases of bullous pemphigoid appearing shortly after in¯uenza vaccination have been described ( 1±3 ).In one of thema relapsedeveloped after further vaccination one year later( 3).Toourknowledge, there is no previous description ofotherbullous diseases appearing after in¯ uenza vaccination. CASE REPORT A90-year-oldwoman was seen with a generalizedbullous eruption.She did not remember su Œeringfrom similar lesions previously.She had hypertension treated for more than one yearwith hydrochlorothiazide and valsartan (Co-diovan â ). Sixweeks before the start of cutaneous lesions, nimodipine (Nimotopâ )andginko biloba ( Tanakene â )hadbeen added toher therapy. In October 2000 she received an in¯ uenza vaccination.She denied intake of paracetamol or any other newdrug. Twelve hours after administration of the in¯ uenza vaccine,she noticed pruritus in her genital area and legs.
