Abstract

Introduction: Generalized pustular psoriasis (GPP) is a rare, severe, and potentially life-threatening systemic and chronic autoinflammatory disease characterized by sterile, neutrophilic pustules. The standard of care for GPP varies by region, with limited information and experience of flares and their treatment. Our aim was to establish current unmet needs in GPP by better understanding the natural history of GPP, examining how dermatologists diagnose GPP and GPP flares, and establishing the range and adequacy of GPP treatment options currently prescribed by dermatologists. Methods: Eligible dermatologists (N = 29) completed a 28-question structured survey, covering ten themes, ranging from GPP diagnostic criteria to GPP symptoms and treatment. Results: All dermatologists stated that pustules were necessary to diagnose a GPP flare. The most frequently reported triggering factors for GPP were steroid withdrawal (64%), infection (58%), and stress (50%). Most dermatologists indicated that available treatment options for GPP flares were adequate “most” (79%) or “all” (14%) of the time. Despite this reported adequacy, 38% of dermatologists reported that it was at least “somewhat common” for a flare to require hospitalization. Furthermore, 72% of dermatologists indicated that treatments were too slow to control flares, and 66% indicated that treatments did not adequately prevent new flares at least “sometimes”. Conclusion: This survey suggests that there are key features of GPP flares, and could initiate discussion around forming consensus guidelines for diagnosis and management. While the results suggest that moderately effective therapies may exist, the need for GPP-specific treatments remains.
