Dermatitis Herpetiformis

Dermatitis herpetiformis (DH) is a chronic, pruriticskin disease associated with gluten sensitivity and often present in conjunction with celiac disease (CD) (gluten-sensitive enteropathy). Untreated disease may lead to continued skin symptoms and complications of enteropathy including iron-deficiency anemia and osteoporosis. Diagnosis of DH or CD should lower the threshold for evaluating for other autoimmune diseases. Individuals with DH have been shown to have a decreased mortality rate compared to those with CD (Hervonen, 2012).

Tabs Content

Clinical Overview

Diagnosis

Indications for Testing

Chronic pruritic blistering dermatitis/skin lesions, classically with clustered papules and vesicles (vesicles may be uncommon due to scratching)

Criteria for Diagnosis

Clinical signs and symptoms
- Pruritic papular and/or vesicular skin lesions in typical locations
Characteristic immunopathology on uninvolved, perilesional skin with direct immunofluorescence
Positive serology consistent with gluten intolerance/celiac disease (CD); rarely increased serum IgA epidermal transglutaminase antibodies only

Laboratory Testing

Should perform at a minimum
- Celiac testing concurrently with immunopathology – see Celiac Disease
  - Biopsy necessary for diagnosis – see cutaneous direct immunofluorescence in Histology
- Epidermal transglutaminase (eTG), also known as transglutaminase type 3 (TG3), IgA antibody testing

Testing for other blistering skin diseases

Due to similarities in clinical presentation, it may be helpful to consider the following tests to assist with the diagnosis of bullous, puritic skin lesions

Testing for Blistering Skin Diseases
Test Number	Test Name	Skin Diseases	Recommended Use
0092001	Pemphigoid Antibody Panel - Epithelial Basement Membrane Zone Antibodies, IgG and IgA, BP180 and BP230 Antibodies, IgG	Pemphigoid Epidermolysis bullosa acquisita Linear IgA bullous dermatosis	Diagnosis Disease activity monitoring
2010905	Collagen Type VII Antibody IgG by ELISA	Epidermolysis bullosa acquisita Some bullous lupus erythematosus	Diagnosis Disease activity monitoring
0090650	Pemphigus Antibody Panel - Epithelial Cell Surface Antibodies and Desmoglein 1 and Desmoglein 3 Antibodies, IgG	IgG variant pemphigus including pemphigus foliaceus and pemphigus vulgaris	Diagnosis Disease activity monitoring
0092106	Pemphigus Antibody IgA	IgA variant pemphigus including intraepidermal neutrophilic IgA dermatosis and subcorneal pustular dermatosis	Diagnosis Disease activity monitoring

In relevant clinical situations, consider

Test Number	Test Name	Skin Diseases	Recommended Use
0092107	Paraneoplastic Pemphigus Antibody Screen	Paraneoplastic pemphigus	Diagnosis
0092283	Herpes Gestationis Factor (Complement-Fixing Basement Membrane Zone Antibody IgG)	Pemphigoid gestationis	Diagnosis

HLA genotyping
- Testing is not generally recommended – may be useful in ruling out CD and/or dermatitis herpetiformis (DH) only in selective clinical situations because of high negative predictive value
- Absence of one of these haplotypes essentially rules out CD and DH
  - HLA-DQ2 (encoded by HLA-DQA1*05 and HLA-DQB1*02)
    - Present in >90% of individuals with DH
  - HLA-DQ8 (encoded by HLA-DQB1*03:02)
    - Present in ~5-10% of individuals with DH

Histology

Skin biopsy for histopathology and perilesional biopsy (3 mm from an active lesion) for direct immunofluorescence is necessary for diagnosis

Differential Diagnosis

Arthropod bites
Bullous impetigo
Bullous lupus erythematosus
Contact dermatitis
Eczema (various types, including atopic and asteatotic)
Epidermolysis bullosa acquisita
Erythema multiforme
Herpes simplex or herpes zoster
IgA vasculitis
Linear IgA bullous dermatosis
Pemphigoid
Pemphigus
Prurigo nodularis
Scabies and other ectoparasites
Urticaria and urticarial vasculitis

Monitoring

Monitor therapy/adherence to gluten-free diet
- IgA endomysial antibodies (EMA)
- IgA tissue transglutaminase antibodies (tTg) – transglutaminase 2 (TG2) enzyme-linked immunosorbent assay (ELISA)
- IgA epidermal transglutaminase (eTG) – transglutaminase 3 (TG3) ELISA
- Patients who are IgA deficient and rare patients without IgA deficiency have IgG EMA and IgG TG2 antibodies without detectable IgA antibodies, which fluctuate with disease activity

Background

Epidemiology

Incidence – 0.4-3.5/100,000; possibly declining
Prevalence – 1.2-75.3/100,000
Age – all ages but uncommon in children; peak onset 20s-40s
Sex – M>F
Ethnicity – most common in those of northern European descent but occurs in all ethnic groups

Risk Factors

Gluten-sensitive enteropathy (GSE), CD
Lymphoma
Autoimmune disease (eg, lupus, thyroiditis, diabetes)
Oral aphthae
First-degree relatives with DH or CD

Pathophysiology and Immunopathophysiology

Skin biopsy specimens from patients with DH demonstrate subepidermal deposition of IgA with neutrophil infiltration
Patients with DH have serum IgA antibodies to tissue transglutaminase (tTG/TG2) and epidermal transglutaminase (eTG/TG3)
Most patients with DH have mild CD; however, only ~5% of individuals with CD will develop DH (Herrero-Gonzalez, 2010)
Strong association with HLA genotype DQ A1*0501, B1*02, which encodes HLA-DQ2 heterodimers

Immunohistology and Dermatopathology

Granular and/or fibrillar deposition of IgA antibodies in dermal papillae and, less commonly, in blood vessels by direct immunofluorescence testing
Classically, a subepidermal blister with neutrophil (and occasionally eosinophil) microabscesses within dermal papillae in fixed-tissue histopathology

Clinical Presentation

Papulovesicular lesions and urticarial wheals in a symmetrical distribution – classically involves extensor elbows and knees, buttocks, scalp, shoulders, sacral areas
Chronic eczematoid skin changes, excoriations – often have intense pruritus, which is attended by secondary skin changes including ecchymoses
Oral lesions are rare
Only ~20% of patients with DH will not have signs (enteropathy) and/or symptoms of CD (Jakes, 2014)
