Bullous Pemphigoid Diagnosis and Treatment
Diagnostic Criteria
- The British Journal of Dermatology recommends that bullous pemphigoid be suspected in patients with tense bullae on an erythematous or urticarial base with severe pruritus, lesions on flexural surfaces, inner thighs, abdomen, and a history of pruritus alone preceding the lesions 1, 2
Treatment Approach
- The British Journal of Dermatology suggests that for extensive bullous pemphigoid in older diabetic patients, clobetasol propionate 0.05% cream be applied to the entire body surface, which provides superior disease control with lower mortality than systemic corticosteroids 4, 5
- The British Journal of Dermatology recommends applying clobetasol propionate 0.05% cream twice daily initially, including to normal skin, blisters, and erosions, sparing only the face, and increasing to maximum 40 g daily if disease control is not achieved within 1-3 weeks 4, 5
Special Considerations
- The British Journal of Dermatology advises monitoring blood glucose closely as topical corticosteroids can affect glycemic control in diabetic patients 4
- The British Journal of Dermatology suggests considering doxycycline 200 mg daily with nicotinamide 500-2500 mg daily as steroid-sparing alternatives given diabetes comorbidity 5
Monitoring and Refractory Disease
- The Praxis Medical Insights guideline recommends following up every 2 weeks for the first 3 months, then monthly for the next 3 months, then every 2 months, and monitoring complete blood count, liver function, glucose, renal function, and blood pressure 5
- The Praxis Medical Insights guideline suggests that rituximab 375 mg/m² weekly for 4 weeks achieves response in 78% of refractory cases 5
