Resum:	Background: Paradoxical psoriasis (PP) is a known adverse event of anti-tumor necrosis factor (anti-TNF) agents in hidradenitis suppurativa (HS), yet evidence regarding its management remains limited. The objective was to assess the effectiveness of interleukin-17 inhibitors (IL-17i) in treating anti-TNF-induced PP in patients with HS. Methods: This multicenter retrospective study included 40 adults with HS who developed PP during anti-TNF therapy and were subsequently treated with IL-17i. Outcomes for PP were measured using the Physician's Global Assessment (PGA); HS severity was evaluated using the International Hidradenitis Suppurativa Severity Score System (IHS4) and Hurley scores. Paired comparisons were performed using the Wilcoxon signed-rank or McNemar's test, as appropriate. Multivariate analysis was performed using LASSO-regularized logistic regression. Missing data were managed by multiple imputation. Results: Of the patients, 27. 5% achieved a clinically meaningful PP response, while 45% experienced worsening. Female sex, older age at HS onset, and prior exposure to secukinumab were associated with nonresponse. Conversely, HS severity improved significantly in 70% of patients (p < 0. 001). Conclusions: IL-17i showed limited effectiveness for anti-TNF-induced PP in HS, though improvement in hidradenitis was observed.
