Purpose Of Review:
The aim of this article is to review articles on mucous membrane pemphigoid published in the English literature from 2006 to 2007.
Recent Findings:
The risk of ocular disease among patients with oral only mucous membrane pemphigoid is estimated at 15-20% at 5 years. Biopsy with direct immunofluorescent testing is essential to confirm the diagnosis because histopathology even with electron microscopy does not appear to be specific enough to confirm the diagnosis of mucous membrane pemphigoid with consistency. Autoantibodies to IgG and IgG4 appear to be the most common findings observed on direct immunofluorescent testing in patients with mucous membrane pemphigoid. Treatment for mucous membrane pemphigoid typically involves immunosuppressive drugs, including biologic therapy, as well as intravenous immunoglobulin, although results have been mixed and the majority of data reported still are from case series and anecdotal evidence.
Summary:
Mucous membrane pemphigoid continues to be a potentially life and sight threatening disease. Therapy for this disease continues to show varied results although benefits are clearly seen in some patients. The immunosuppressive drugs used for treating mucous membrane pemphigoid and certain definitive categories of mucous membrane pemphigoid continue to evolve.
Insights
Mucous membrane pemphigoid is a serious condition with a 15-20% risk of eye complications. Diagnosis requires biopsy and direct immunofluorescence, while treatment involves immunosuppressants with varied outcomes.
Area of Science:
- Dermatology
- Immunology
Background:
- Mucous membrane pemphigoid (MMP) is a chronic autoimmune blistering disease.
- It can lead to significant morbidity, including sight-threatening ocular complications.
Purpose of the Study:
- To review the English literature on mucous membrane pemphigoid published between 2006 and 2007.
- To summarize current understanding of diagnosis, risk factors, and treatment.
Main Methods:
- Literature review of articles published from 2006-2007.
- Analysis of diagnostic methods, particularly biopsy and direct immunofluorescence.
- Review of treatment modalities, including immunosuppressive drugs and biologic therapy.
Main Results:
- An estimated 15-20% of patients with oral-only MMP develop ocular disease within 5 years.
- Direct immunofluorescence is crucial for diagnosis, as histopathology alone lacks specificity.
- Autoantibodies, particularly IgG and IgG4, are common findings in direct immunofluorescence.
- Treatment with immunosuppressants and intravenous immunoglobulin shows mixed results, with much data from case series.
Conclusions:
- Mucous membrane pemphigoid remains a potentially life- and sight-threatening disease.
- Therapeutic outcomes for MMP are variable, though some patients show clear benefits.
- Ongoing evolution in the understanding and treatment of MMP, including specific drug categories, is noted.
