Comparison between super-responders and nonsuper-responders in psoriasis under adalimumab treatment: a real-life cohort study on the effectiveness and drug survival over one-year.

Background: Data on the characteristics and treatment outcomes of super-responders and non-superresponders in psoriasis under adalimumab treatment are limited. Methods: A retrospective analysis from psoriatic patients treated with adalimumab was compared to characterize super-responders vs non-super-responders’ groups, identify factors associated with super response, and assess treatment outcomes after switching. Results: 15 out of 70 (21.4%) patients were categorized as super-responder. The proportion of patients achieving a PASI 100 response was significantly higher in super-responders than non-super-responders at weeks 12, 24, and 52. Female sex and Charlson Co-morbidity Index were significantly associated with super-responders. A high level of high-density lipoprotein was independently associated with PASI 90 response at weeks 24 and 52. Additionally, nearly 35%–43% of non-super-responders switching to interleukin-17A (IL-17A) inhibitors may achieve a PASI 100 response at week 12. In contrast, all super-responders switching to IL-17A inhibitors achieved a PASI 100 response at week 4. Conclusions: Super-responders treated with adalimumab have a higher rate of being female and fewer comorbidities. And super-responders have better PASI responses than non-super-responders, whether the patients were treated with adalimumab or switched to IL-17A inhibitors. [ABSTRACT FROM AUTHOR]
