The population-based Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey was designed to better understand patient and dermatologist perceptions of the disease burden of psoriasis (PsO) and their treatment expectations. UPLIFT was a cross-sectional, quantitative, online survey conducted in Europe, North America, and Japan between 2 March and 3 June 2020. In Japan, 391 patients reporting a diagnosis of PsO and/or psoriatic arthritis (PsA) were surveyed (75% had PsO alone, 23% had PsO and PsA, and 2% had PsA alone). Self-reported body surface area (BSA) data were available for 309 Japanese patients, with the majority (80%) reporting PsO-involved BSA ≤3 palms. Current symptoms of PsO were rated as moderate or severe by 43% of Japanese patients with BSA ≤3 palms, and severe by 44% of patients with BSA 4-10 palms. PsO frequently occurred in ≥1 special areas, most commonly the scalp in 76% of Japanese patients with BSA ≤3 palms, and ≥90% of those with BSA ≥4 palms. Furthermore, musculoskeletal symptoms in 42% of patients with PsO alone were suggestive of PsA. Whereas Japanese patients with BSA ≤3 palms mainly reported receiving topical therapy alone (34%) or no treatment (32%), 64% patients with BSA 4-10 palms reported receiving systemic therapy. Overall, 21% of Japanese patients with self-perceived mild symptoms of PsO and 48% of patients with special area involvement experienced at least a moderate impact of disease on quality of life (Dermatology Life Quality Index score >5). Moreover, patients and dermatologists differed in their perceptions of determinants of PsO severity and treatment, and office visit discussions. In general, these findings from the Japanese subgroup of the UPLIFT survey demonstrated that a high proportion of patients perceived their symptoms to be moderate or severe irrespective of the level of skin involvement, suggesting a persistent unmet treatment need.
