Effectiveness of Guselkumab for the Treatment of Moderate-to- Severe Psoriasis in Elderly Patients: A Retrospective, Real-World Multicenter Study in the Lazio Region
Year: 2026
Type: article
Study design: Observational Study
Abstract: BACKGROUND: Guselkumab, a selective interleukin-23 inhibitor, is effective in moderate-to-severe plaque psoriasis, but real-world long-term data in elderly patients remain limited. OBJECTIVE: To evaluate the long-term effectiveness of guselkumab in elderly patients with moderate-to-severe psoriasis in a real-world setting. METHODS: This retrospective, multicenter study included 102 patients aged 65 years or older treated with guselkumab across seven Italian centers. PASI scores and PASI 75/90/100 responses were assessed as observed cases at weeks 4, 16, 28, and 52, and annually up to 4 years, with last-observation-carried-forward and non-responder imputation as sensitivity analyses. Subgroups by biologic experience and BMI were analyzed. RESULTS: < 0.001). At week 52 and year 4, PASI 90 was achieved by 89.7% and 86.5%, and PASI 100 by 79.3% and 73.0%, respectively. Responses were comparable between biologic-naïve and biologic-experienced patients. Obese patients had higher baseline PASI; after adjustment for baseline severity, responses did not differ from non-obese patients. CONCLUSIONS: Guselkumab was associated with high and durable PASI improvement in elderly patients, regardless of prior biologic exposure or body weight. The retrospective design and absence of systematic safety data warrant cautious interpretation.
