{Abstract}: <B>UNASSIGNED: </B>Real-world data on health-related quality of life (HRQoL) in palmoplantar pustulosis (PPP) are scarce and few studies have analysed the generic HRQoL.<BR><B>UNASSIGNED: </B>To assess HRQoL using the generic EQ-5D instrument and the Dermatology Life Quality Index (DLQI) instrument in PPP compared to plaque psoriasis.<BR><B>UNASSIGNED: </B>Cross-sectional data from PsoReg, the Swedish National Registry for Systemic Treatment of Psoriasis (2006-2021), were examined. The study included 306 patients with PPP, out of which 22% had concomitant plaque psoriasis (n = 68), and 7041 patients with plaque psoriasis only. EQ-5D and DLQI were compared between patients with PPP and patients with plaque psoriasis, overall and stratified by sex. A subgroup analysis compared outcomes for patients with PPP vs. patients with severe plaque psoriasis (Psoriasis Area and Severity Index ≥10). Multiple regression analyses were performed to control for potential confounders (age, sex, comorbidities, lifestyle factors).<BR><B>UNASSIGNED: </B>Patients with PPP were to a larger extent female (79% vs. 37%, p < .01) and older (mean [SD] age 59.9 [11.9] vs. 50.7 [16.0] years, p < .01) than patients with plaque psoriasis. EQ-5D values were significantly lower (worse) in patients with PPP (mean [SD] 0.622 [0.309]) compared to patients with plaque psoriasis (mean [SD] 0.715 [0.274]). No significant difference was observed compared to patients with severe plaque psoriasis (p = .237). DLQI was comparable in PPP and plaque psoriasis patients (p = .117). In the regression analyses, PPP only and PPP with plaque psoriasis were associated with lower EQ-5D values of 0.065 (p < .01) and 0.061 points (p < .10) compared to plaque psoriasis patients.<BR><B>UNASSIGNED: </B>PPP had a substantial negative impact on patients' generic and dermatology-specific HRQoL. Patients with PPP were worse off in terms of generic HRQoL compared with patients with plaque psoriasis when controlling for the impact of potential confounders.<BR>Real-world data on health-related quality of life in palmoplantar pustulosis (PPP) are scarce and previous studies have been predominantly restricted to the Dermatology Life Quality Index.This study also shows a significant impairment of the generic HRQoL (assessed by the generic EQ-5D instrument) in patients with PPP.Patients with PPP rated their generic HRQoL worse than patients with plaque psoriasis.
