There are still many unanswered questions regarding the pathophysiology, course and treatment options of pustular psoriasis. Because it is a rare condition, there is a lack of large cohort data to date. Therefore, based on the “European Rare and Severe Psoriasis Expert Network”, the IRASPEN registry study was launched to gain new insights into different aspects of the disease and its treatment.<\/strong><\/p>\n

Psoriasis is a chronic, immune-mediated inflammatory disease in which both erythematous and pustular lesions may occur. These differ clinically and histologically, but occur in a clustered, coincident manner [1]. Occasionally, pustular skin manifestations can be observed dermatoscopically in inflammatory plaques of psoriasis vulgaris, as described by Barber and K\u00f6nigsbeck [2]. This led to the assumption that primary pustular skin lesions are part of the psoriasis spectrum, so that they are grouped together under the term psoriasis pustulosa (PP). Pustular forms of psoriasis are rare and pose a challenge in clinical practice [3]. In Generalized Pustular Psoriasis (GPP), in addition to pustular skin manifestations, a life-threatening multisystemic inflammatory reaction may occur. The ERASPEN criteria [2,4] (box)<\/span> serve as the basis for the diagnostic classification of GPP. Palmoplantar pustulosis (PPP) is characterized by eruptive sterile vesicles and erythematous plaques on the palms and soles. In “Acrodermatitis continua suppurativa Hallopeau”, red, scaly foci with pustules form with a tendency to spread slowly starting from the tips of the fingers and toes.<\/p>\n

IRASPEN: International Rare and Severe Psoriasis Expert Network<\/h2>\n

The aim of the prospective international registry study IRASPEN is primarily to describe the disease course and the different subtypes of pustular psoriasis [2,5]. Furthermore, it is hoped that the acquisition of genetic data and the investigation of molecular pathways will lead to a better understanding of clinical and pathophysiological processes. Another goal is to assess existing treatment options and identify “unmet needs.” The IRASPEN registry is planned to include at least 180 patients worldwide, including 140 with Palmoplantar Psoriasis (PPP), 20 with Generalized Pustular Psoriasis (GPP) and 20 with Acrodermatitis Continua of Hallopeau (ACH), as well as 360 unaffected relatives. The main inclusion criteria are: Age \u22656 months and a confirmed diagnosis of pustular psoriasis (PP) with an active episode within the last 6 months. It may be GPP, PPP or ACH or a mixed phenotype. Eight measurement time points are planned within the 5-year observation period, as well as flexible follow-up appointments for acute relapses. Patient-reported outcomes measurement tools (DLQI, EQ-5D, WPAI-GH, PSS, VAS pain and disease activity) and physician-collected assessments (GPPASI, GPPGA, PPP ASI, NAPSI) will be used. In addition, photodocumentation and lesion counts are performed and genetic material is collected (blood and skin biopsies).<\/p>\n
