Palmoplantar pustulosis – a cross-sectional analysis in Germany

摘要

Background: Palmoplantar pustulosis (PPP) is arecalcitrant chronic inflammatory skin disease. Datarelevant for the medical care of patients with PPP arescarce. Thus, the aim of this work was to investigatethe disease burden, clinical characteristics, andcomorbidity of PPP patients in Germany. Patientsand Methods: PPP patients were examined in a crosssectionalstudy at seven specialized psoriasis centersin Germany. Results: Of the 172 included patients withPPP, 79.1% were female and 69.8% were smokers.In addition, 25.0% suffered from psoriasis vulgaris,28.2% had documented psoriatic arthritis, and 30.2%had a family history of psoriasis. In 77 patients themean Dermatology Life Quality Index (DLQI) was 12.2± 7.7 (mean ± SD). The mean Psoriasis PalmoplantarPustulosis Area and Severity Index (PPPASI) was 12.6 ±8.6. Mean body mass index was above average at 27.1± 5.5. The PPP patients had previously received anaverage of 2.6 ± 2.1 different anti-psoriatic systemicdrugs or UV-therapies. The systemic drugs that hadbeen used most frequently were corticosteroids in40.1% of patients, followed by acitretin (37.8%), andmethotrexate (27.9%). The PPPASI was 13.4 ± 8.9 inpatients without current systemic therapy and 10.4 ±7.9 in patients with systemic therapy. Conclusion: ManyPPP patients had a concomitant diagnosis of psoriasisvulgaris and/or psoriatic arthritis or had a familyhistory of psoriasis. Despite the fact that many of thepatients were using anti-psoriatic therapies, there wasstill a high burden of disease within this PPP cohort.This insufficient control of symptoms demonstratesthe urgent need for new PPP treatments.
