Study Notes
Pemphigus Treatment and Management
- Rituximab demonstrates higher complete remission rates compared to prednisone, with up to 58% achieving remission off therapy versus 34% with prednisone.
- Primary treatment options include steroids and steroid-sparing agents such as azathioprine and mycophenolate.
- Initial assessment of disease should include evaluating the extent of skin and mucosal involvement and any existing comorbidities.
- Prognosis is influenced by patient age and overall health status; complications can arise from immunosuppressive treatments.
- Lesion assessment using the Autoimmune Bullous Skin Intensity and Severity Score (ABSIS) or Pemphigus Disease Area Index (PDAI) is crucial for treatment planning.
- Dermatology-specific quality of life impacts should be measured using DLQI and other tools tailored to autoimmune blistering diseases.
Clinical Evaluation
- Record hematological, oncological, endocrine, and infectious histories to identify risk factors.
- Pemphigus typically features flaccid bullae that may progress to erosions, especially in seborrhoeic areas like the chest and scalp; it is usually not itchy.
- Nail involvement is possible, and lesions can emerge at mechanically stressed sites.
Histopathological Analysis
- Skin biopsies should be collected from perilesional areas for routine histopathology analysis to confirm diagnosis.
- Pemphigus vulgaris (PV) shows intraepidermal suprabasal acantholysis, while pemphigus foliaceus (PF) displays acantholysis at the granular layer.
Treatment Protocols
- In severe or refractory cases, adjunctive treatments such as intravenous immunoglobulins (IVIG) may be considered.
- High-potency topical corticosteroids (like clobetasol) can be applied directly to local oral erosions for symptomatic relief.
- Careful management of corticosteroid dosing is recommended, considering the risk of relapse correlated with anti-Dsg1 levels.
Monitoring and Follow-Up
- Regular serological monitoring for anti-Dsg1 and Dsg3 autoantibodies helps assess disease activity and guide treatment adjustments.
- If relapses occur during corticosteroid tapering, consider reintroducing rituximab treatments.
- Patients receiving immunosuppressive therapy should be vaccinated against common pathogens, avoiding live vaccines.
General Recommendations
- Adjust prednisone tapering schedules based on individual risk assessments and relapse history.
- Evaluate treatment response regularly to accommodate changes in disease activity and patient condition.
