• Background: Erythrodermic psoriasis (EP) remains challenging to manage because it is rare and has complex complications. Although acitretin is recommended as an appropriate choice for EP, there is a lack of large-scale evidence. Objectives: This study aims to assess the efficacy and safety of acitretin as systemic monotherapy in EP patients. Design: We retrospectively analyzed data from patients with EP who received at least 3 months of acitretin as systemic monotherapy during hospitalization and out-patient follow-up from January 2005 to May 2021 at the Peking Union Medical College Hospital, China. Methods: The efficacy was clinically evaluated after 1, 2, 4, and 12 weeks of treatment, which was classified as a good response (>75% of lesions cleared), partial response (50%–75% cleared), moderate response (25–50% cleared), or no response (<25% cleared). Safety was assessed on the basis of physical examination results and significant changes in laboratory examination results after 12 weeks of treatment. Results: Overall, 81 patients (79.0% men; mean age, 47.9 years) were included. The acitretin dose ranged from 20 to 60 mg/day (0.3 to 0.8 mg/kg/day). The rates of good, partial, and moderate responses were 0.0%, 2.5%, and 42.0% at 1 week; 3.7%, 34.6%, and 61.7% at 2 weeks; 29.6%, 58.0%, and 12.4% at 4 weeks; and 85.2%, 13.6%, and 1.2% at 12 weeks after treatment initiation, respectively. EP patients transformed from psoriasis vulgaris showed a higher good/partial response rate compared with that of EP patients that developed from pustular or articular psoriasis (44.6% vs. 14.3%, p = 0.035). Patients with concurrent infection showed a lower rate of good/partial response compared with that of those without concurrent infection (16.7% vs. 44.4%, p = 0.049). Adverse effects were seen in 45 (55.6%) patients in 12 weeks, and dyslipidemia (n = 31; 38.3%), xerosis (n = 24; 29.6%), and elevated liver enzymes (n = 6; 7.4%) were most commonly reported. Twenty-three patients were followed up for over 3 years, and six (26.1%) patients had EP recurrence. Conclusions: Acitretin as a systemic monotherapy showed satisfactory effectiveness for EP, especially in patients developed from psoriasis vulgaris and without infection.
