Abstract

Background Psoriasis is a chronic immune-mediated inflammatory disease. Beyond the physical dimensions, the disease has an extensive emotional and psychosocial effect on patients, influencing their quality of life, social life and interpersonal relationships. Thus patient-reported outcomes are a crucial instrument for the evaluation of disease burden. Navigating life in times of the COVID-19 pandemic is challenging, especially for persons suffering from chronic diseases. We here analyzed the impact of lockdown restrictions on psoriasis patients. Objective To compare the Dermatology Life Quality Index (DLQI) before and during the COVID-19 pandemic of patients with psoriasis. Methods Retrospective longitudinal analysis in adult patients with moderate to severe psoriasis undergoing biologic treatment between January 2020 and January 2021. DLQI, patient demographics, Psoriasis Area and Severity Index (PASI), and recent biologic treatment were recorded. Results 103 patients were identified, of whom 19 had additional psoriatic arthritis. Female (n = 29) and male (n = 74) patients were distributed 1 to 3. Median age of patients was 54 years (range 18–85). All patients received biologic systemic treatment: anti-IL-23 (n = 39), anti-IL-17A (n = 30), anti-IL-12/23 (n = 25), or anti-TNFα (n = 9). Comparing DLQI scores before the COVID-19 pandemic and under lockdown restriction showed improved DLQI scores over time. Further analysis displayed that patients mostly ticked “not relevant” on social activities during lockdown. Thus, the DLQI scores may be artificial improved and may not really reflect the actual disease burden. Conclusions Psoriasis patients showed a contrary improvement of life quality despite harsh COVID-19 lockdown suggesting that DLQI should be modified when social life is restricted.
