What type of hypersensitivity is mucous membrane pemphigoid?
It is characterised by a type II hypersensitivity reaction against bullous pemphigoid 180 (BP180),1 laminin 52 and β4 integrin3 as the predominant antigens,4 with linear deposition of IgG, IgA, or C3 along the epithelial basement membrane zone (BMZ).
What is pemphigoid in the eye?
Mucous membrane pemphigoid (MMP), often called ocular cicatricial pemphigoid (OCP), is a rare ocular surface disease usually due to an autoimmune reaction of the patient’s body to the cells in the conjunctiva and eventually the cornea. It often begins with the feeling of dryness and irritation.
Is cicatricial pemphigoid a genetic disorder?
A combination of environmental and genetic factors appear to play a role in the susceptibility of developing cicatricial pemphigoid.
How common is ocular cicatricial pemphigoid?
Ocular cicatricial pemphigoid is present in about 60 to 70 percent of patients with mucous membrane pemphigoid. This activity reviews the evaluation and management of ocular cicatricial pemphigoid and highlights the role of the interprofessional team in caring for affected individuals.
How is ocular pemphigoid diagnosed?
Diagnosis can be confirmed by conjunctival biopsy showing linear antibody deposition on the basement membrane. A negative biopsy result does not rule out the diagnosis.
Is cicatricial alopecia an autoimmune disorder?
Cicatricial (scarring) alopecia results from irreversible damage to epithelial stem cells located in the bulge region of the hair follicle, generally as a result of inflammatory mechanisms (eg, in the context of autoimmune disease).
Is pemphigoid an autoimmune disease?
Pemphigus is an autoimmune disorder. Normally, your immune system produces antibodies to fight off harmful invaders, such viruses and bacteria. But in pemphigus, the body produces antibodies that damage cells of your skin and mucous membranes.
What is the difference between pemphigoid and pemphigus?
Pemphigus is characterized by shallow ulcers or fragile blisters that break open quickly. Pemphigoid presents with stronger or “tense” blisters that don’t open easily. Those with pemphigoid are also more likely to have hot, red and itchy hive spots.
What is ocular cicatricial pemphigoid?
Ocular Cicatricial Pemphigoid is thought about a subtype of Mucous Membrane Pemphigoid (abbreviated MMP), and these terms are in some cases used interchangeably. Ocular Cicatricial Pemphigoid is a kind of autoimmune conjunctivitis that leads to cicatrization (i.e. scarring) of the conjunctiva.
What are the possible complications of ocular cicatricial pemphigoid (OCP)?
Ocular Cicatricial Pemphigoid Complications. Seemingly minor surgical intervention and conjunctival trauma can lead to major worsening of disease. Surgical intervention, such treatment of trichiasis, entropion and cataract ought to be delayed if possible until control of active disease is achieved.
How effective is cyclophosphamide in the treatment of ocular cicatricial pemphigoid (CP)?
The Systemic Immunosuppressive Therapy for Eye Diseases (SITE) trial discovered that cyclophosphamide was effective in managing inflammation in 70.7% of patients with Ocular Cicatricial Pemphigoid at 1 year, with 66.9% patients on less than or equal to 10mg of prednisone.
What is the role of systemic therapy in ocular cicatricial pemphigoid (MMP)?
Systemic therapy is required in Ocular Cicatricial Pemphigoid as ocular participation comprises a high risk subset of MMP and is insufficiently treated with topical therapy alone.
