Do high pemphigoid antibody titres without skin signs or symptoms require treatment?

From the Guidelines

High pemphigoid antibody titres without skin signs or symptoms generally do not require treatment. Pemphigoid antibodies alone, in the absence of clinical manifestations, represent a serological finding rather than active disease requiring intervention. Monitoring is recommended instead of immediate treatment, with clinical evaluations every 3-6 months to check for the development of skin lesions or symptoms.

Key Considerations

• If a patient remains asymptomatic despite positive antibodies, treatment is unnecessary as it would expose them to potential medication side effects without clear benefit, as seen in the management guidelines for pemphigus vulgaris 1.
• The presence of antibodies may indicate a predisposition to developing bullous pemphigoid in the future, but many individuals with positive serology never develop clinical disease.
• Should symptoms eventually appear (blisters, intense pruritus, erythematous plaques), treatment would then be indicated, typically starting with topical corticosteroids for mild disease or systemic therapy for more extensive involvement.

Treatment Approach

• The decision to treat should always be based on clinical disease rather than serological findings alone, emphasizing the importance of clinical judgment in managing patients with pemphigoid antibody titres.
• Treatment guidelines, such as those outlined for pemphigus vulgaris, suggest a stepped approach, starting with first-line therapies like corticosteroids and considering adjuvant immunosuppressants or alternative treatments based on disease severity and response 1.

Patient Management

• Regular follow-up is crucial for patients with high pemphigoid antibody titres without symptoms to promptly identify any emergence of clinical disease.
• Patient education on the signs and symptoms of pemphigoid and the importance of adherence to monitoring schedules is vital for early detection and effective management of potential disease onset.

From the Research

High Pemphigoid Antibody Titres Without Skin Signs or Symptoms

• The provided studies do not directly address whether high pemphigoid antibody titres without skin signs or symptoms require treatment 2, 3, 4, 5, 6.
• However, the studies discuss the treatment of pemphigoid diseases, including bullous pemphigoid and pemphigus vulgaris, which are characterized by autoantibodies against structural proteins of the dermal-epidermal junction 4.
• The treatment options for pemphigoid diseases include immunosuppressive therapy, such as azathioprine and mycophenolate mofetil, which are used to minimize corticosteroid-related adverse effects 2, 5, 6.
• The studies also discuss the use of rituximab and immunoadsorption as treatment options for severe pemphigus 3.
• It is not clear from the provided studies whether high pemphigoid antibody titres without skin signs or symptoms would require treatment, as the studies primarily focus on the treatment of symptomatic pemphigoid diseases.

Treatment Options for Pemphigoid Diseases

• Azathioprine and mycophenolate mofetil are commonly used as adjuvant therapy in combination with corticosteroids to treat pemphigoid diseases 2, 5, 6.
• Rituximab and immunoadsorption may be used as treatment options for severe pemphigus 3.
• The choice of treatment may depend on the severity of the disease, the presence of skin signs or symptoms, and the patient's overall health status.
