Background
Pemphigus herpetiformis is a clinical variant of pemphigus that combines the clinical features of dermatitis herpetiformis with the immunopathologic features of pemphigus. Previously, pemphigus was described using various terms, including herpetiform pemphigus, acantholytic herpetiform dermatitis, pemphigus controlled by sulfapyridine, and mixed bullous disease. Because pemphigus herpetiformis is a clinical variant of pemphigus, it may be more appropriately described with a term that begins with the general group term (pemphigus), followed by a term for the variant subset (herpetiformis), similar to the terms for other pemphigus variants, such as pemphigus vulgaris, pemphigus foliaceus, pemphigus erythematosus, and pemphigus vegetans.
Pathophysiology
Pemphigus herpetiformis appears to be mediated by the immunoglobulin G (IgG) class of autoantibodies that target the skin epidermis desmoglein components. Most patients demonstrate autoantibodies to desmoglein 1, a desmosomal component predominantly located in the upper epidermis, while a minority of patients demonstrates autoantibodies to desmoglein 3, which is predominantly located in the lower epidermis. The ability of desmoglein 3 to induce an experimental model of pemphigus after transfer of splenocytes from desmoglein 3-immunized desmoglein 3-knockout mice to Rag-2 immunodeficient mice further supports the role of desmogleins as autoantigens. Histologically demonstrated eosinophil and/or neutrophil infiltration into the epidermis may be relevant pathogenically in the disease process of pemphigus herpetiformis.[1]
In the neutrophil-dominant subset, epidermal cells secrete a neutrophil chemokine interleukin 8 (IL-8), which apparently is induced by IgG autoantibodies to desmoglein and may be responsible for the recruitment of neutrophils to the epidermis, resulting in the subsequent blistering process.
Epidemiology
Frequency
United States
Pemphigus herpetiformis is a rare clinical variant of pemphigus. Frequency of occurrence remains undetermined.
International
Although frequency of occurrence of pemphigus herpetiformis is not determined, pemphigus herpetiformis has been reported in Europe, Japan, and the United States. In a large study conducted in Eastern Europe, 15 patients (7.3%) with pemphigus herpetiformis were found among 205 patients with pemphigus. In a smaller study conducted in Italy, 5 patients with pemphigus herpetiformis were found among 84 patients with pemphigus. Therefore, pemphigus herpetiformis accounts for approximately 6-7% of pemphigus in European populations.
Mortality/Morbidity
Pemphigus herpetiformis is not associated with significant mortality; however, pemphigus herpetiformis is associated with significant pruritus. Treatment regimens for pemphigus herpetiformis may cause significant adverse effects that must be monitored closely by the patient's physicians. Severe pruritus is noted in approximately one half of patients affected with pemphigus herpetiformis. At least 2 cases of pemphigus herpetiformis have been reported to occur in association with lung cancer. Whether this association was coincidental is not clear.[2, 3] In addition, pemphigus herpetiformis has been associated with prostate cancer development in one case.[4]
Race
Because pemphigus herpetiformis is rare, ethnic distribution is not determined yet. Because pemphigus herpetiformis occurs in the United States, Europe, and Asia, it does not appear to have a specific ethnic predominance.
Sex
Because pemphigus herpetiformis is rare, sex distribution has yet to be defined clearly. Studies in the literature do not appear to support a sex predilection.
Age
The age of onset for pemphigus herpetiformis ranges from 30-80 years, with a mean age of onset of 60 years.
