Pemphigus Vulgaris

Pemphigus Vulgaris (PV) is a rare, severe autoimmune blistering disease characterized by the loss of intercellular connections between keratinocytes (acantholysis). It primarily affects the skin and mucous membranes, resulting in fragile, painful bullae that rupture easily, leaving raw, denuded areas. If untreated, the condition is potentially fatal due to fluid loss, electrolyte imbalance, and secondary infections.

PV is an autoimmune disorder triggered by the production of autoantibodies against desmoglein 1 and 3 (desmosomal proteins). Genetic predisposition (specifically HLA-DRB10402 and HLA-DQB10503 alleles) plays a significant role. Environmental triggers may include certain medications (e.g., penicillamine, captopril) and physical stressors like UV radiation or thermal burns.

The primary mechanism involves IgG autoantibodies binding to desmoglein (Dsg) proteins within desmosomes. This binding triggers intracellular signaling and enzyme activation (plasminogen activators), causing the breakdown of cellular adhesion (acantholysis). This loss of cohesion leads to intraepidermal blistering, occurring just above the basal layer (suprabasal clefting).

PV typically manifests in adults between the ages of 40 and

1. There is no significant gender predilection. Prevalence varies globally, often higher in populations of Ashkenazi Jewish, Mediterranean, and Middle Eastern descent.

• Genetic predisposition (HLA alleles)
• Drug exposure (thiol-containing drugs)
• Age (40–60 years)
• History of autoimmune disease
• Environmental triggers (e.g., UV exposure)

A. Early Symptoms

• Oral mucosal erosions


• Persistent painful mouth ulcers


• Gingival inflammation B. Common Symptoms


• Fragile, flaccid bullae


• Positive Nikolsky sign (skin shears with light pressure)


• Erosions on the scalp or trunk C. Advanced Symptoms


• Extensive body denudation


• Profound pain


• Secondary bacterial skin infections D. Emergency Symptoms


• High fever


• Sepsis


• Severe dehydration


• Difficulty swallowing or breathing due to airway involvement

Inspection reveals flaccid bullae that rupture, leaving painful erosions. Palpation demonstrates a positive Nikolsky sign and an Asboe-Hansen sign (blister extension on pressure). Oral cavity assessment usually shows ulcerative stomatitis.

A. Clinical Assessment: History of mucosal involvement and physical sign testing.
B. Laboratory Testing: ELISA for anti-Dsg1 and anti-Dsg3 antibodies.
C. Imaging Studies: Generally not required unless assessing for underlying malignancy (paraneoplastic).
D. Functional Tests: Not applicable.
E. Biopsy Findings: Direct Immunofluorescence (DIF) showing intercellular IgG/C3 deposits; histology showing suprabasal acantholysis.
F. Genetic Testing: Not routinely performed.
G. Differential Diagnosis: Bullous pemphigoid, Cicatricial pemphigoid, Stevens-Johnson Syndrome.

Test Name: Anti-Desmoglein 1 & 3 ELISA
Type: Blood Test
Purpose: Identify autoimmune antibodies
Expected Findings: Elevated IgG
Interpretation: Diagnostic confirmation

Typically not indicated for routine PV. Chest X-rays may be ordered if paraneoplastic pemphigus is suspected, to check for underlying thymoma or lymphoma.

• Bullous Pemphigoid (deeper subepidermal, less mucosal involvement)
• Erythema Multiforme (target lesions)
• Lichen Planus (erosive form)

• Secondary sepsis
• Electrolyte imbalance
• Chronic steroid side effects (osteoporosis, hyperglycemia)
• Malnutrition due to oral pain

A. Lifestyle Modifications: Soft diet, oral hygiene.
B. Preventive Measures: UV protection, avoidance of culprit medications.
C. Medical Treatment: Corticosteroids (Prednisone), Immunosuppressants (Azathioprine, Mycophenolate Mofetil), and Biologics (Rituximab).
D. Surgical Treatment: Wound debridement.
E. Interventional Procedures: Plasmapheresis.
F. Rehabilitation: Physical therapy for chronic cases.
G. Emergency Management: IV fluids, electrolyte correction, ICU admission for sepsis.

Historically fatal, but the prognosis has improved significantly with modern immunosuppressive therapy. Most patients achieve disease remission, though long-term maintenance therapy is often required.

No primary prevention exists. Secondary prevention involves regular monitoring for signs of relapse and medication side effects.
