Abstract

Recent advances in biologic treatments have made clear skin a realistic treatment goal for psoriasis. However, clear skin may not uniformly translate to an absence of impact on patients' quality of life. This retrospective observational study aimed to elucidate the factors influencing patient‐reported outcomes in patients with psoriasis who have demonstrated successful clinician‐reported outcomes on using biologics. A total of 96 patients who have achieved a ≥75% improvement in Psoriasis Area and Severity Index (PASI) scores with ≥6 months of biologic treatment were included. Their median PASI score was 0.4, with 37.5% having achieved PASI 100 (clear skin). Furthermore, 47.9% reported no impact of psoriasis on their quality of life (Dermatology Life Quality Index [DLQI] score 0 or 1), while 52.1% reported a negative impact (DLQI score ≥2). Notably, 28.1% of the participants had a history of biologic treatment failure, defined as the inability to achieve or sustain a 75% PASI improvement with the previously used biologic agent. Multivariable logistic regression analysis revealed a positive association between achieving PASI 100 and reporting no impact of psoriasis on quality of life (adjusted odds ratio [aOR] 3.88, 95% confidence interval [CI] 1.49–10.91, P = 0.007). Conversely, prior biologic treatment failure was negatively associated with reporting no impact of psoriasis on quality of life (aOR 0.13, 95% CI 0.02–0.65, P = 0.023). Furthermore, among patients with clear skin, those with experience of previous biologic treatment failure reported significantly lower quality of life than those without such experience (P = 0.033). In conclusion, minimal residual skin lesions and prior biologic treatment failure were associated with poorer patient‐reported outcomes in patients with psoriasis. Opting for a biologic agent with the highest predicted efficacy, rather than pursuing a "step‐up" approach with a higher possibility of treatment failure, may be a more suitable strategy in the biologic treatment of psoriasis.
