ActiPso: definition of activity types for psoriatic disease: A novel marker for an advanced disease classification.

BACKGROUND: Assessment of psoriasis is exclusively done measuring severity using somatic scores such as the psoriasis area and severity index or patient-reported outcomes such as the dermatology life quality index. There is no established tool to measure a patient's individual psoriasis activity over time. OBJECTIVES: Development of a new tool to classify psoriasis activity types. METHODS: Open patient interviews were performed and adapted in several steps and by using different groups of patients. Wording of the tool's axis and description how to use it was optimized with the input of patients. The final ActiPso tool was used in a prospective study in psoriasis patients. RESULTS: Four activity types could be identified describing psoriasis intensity (e.g. severity, itch, pain) over one typical year and an event/trigger type describing flares. In the study in 586 psoriasis patients of the 536 patients eligible for analysis 40.9% self-classified as type 1 ('stable'), 22.6% as type 2 ('unstable'), 30.6% as type 3 ('winter type') and 6.0% as type 4 ('summer type'), respectively. Flares of psoriasis as identified by the event/trigger type were reported in 36.1% of patients with activity type 1, 67.8% with type 2, 73.8% of type 3 and 59.4% of type 4, respectively. CONCLUSIONS: Interviewed patients were able to describe their course of psoriatic disease and to name potential triggering factors. By doing so, activity types of psoriasis were defined for the first time and the importance of events/triggers for flares described and integrated into ActiPso types as a basis for advanced patient-centric management. A limitation of ActiPso is that in regions with no seasonal variations types 3 and 4 may not apply.

[Perception of stigmatization in people with psoriasis-qualitative analysis from the perspective of patients, relatives and healthcare professionals]. / Stigmatisierungserleben bei Psoriasis ­ qualitative Analyse aus Sicht von Betroffenen, Angehörigen und Versorgern.

BACKGROUND: Numerous studies have shown that psoriasis is associated with severe losses in almost all dimensions of health-related quality of life. An important aspect is the stigmatization experience of those affected. OBJECTIVE: The aim of this study was to examine the perception of stigmatization from the perspective of patients, relatives and healthcare professionals using a qualitative approach. MATERIAL AND METHODS: Qualitative surveys in the form or focus groups and interviews with patients, relatives and healthcare providers were conducted. The data were analyzed by qualitative content analysis. RESULTS: The results show that stigmatization is perceived by all groups surveyed. It also became clear that self-stigmatization plays a special role. Affected persons, relatives and medical care providers described self-stigmatization as the greatest burden or restriction of affected persons in various areas of life, such as work, leisure and partnership. There were no crucial differences between sex or age groups. CONCLUSION: Possible knowledge deficits of non-affected persons and wrong assumptions of the affected persons about the attitudes of non-affected persons can be reduced, for example, in the context of encounters between affected persons and non-affected persons as well as between affected persons and medical care providers and thus reduce the public as well as the self-stigma.
