Background:
Novel biologics targeting the IL23/T-17 axis, such as tildrakizumab, have been developed to treat psoriasis. There is limited evidence on the use of tildrakizumab for the treatment of psoriasis in difficult-to-treat areas.
Objective:
Our aim was to evaluate the short-term efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis and with the involvement of difficult-to-treat areas.
Methods:
A multicentric retrospective study was conducted on patients who initiated tildrakizumab between July 2022 and July 2023. Psoriasis Area and Severity Index (PASI), Psoriasis Scalp Severity Index (PSSI), Palmoplantar Psoriasis Area and Severity Index (ppPASI), and Nail Psoriasis Severity Index (NAPSI) were measured at baseline and after 16 weeks. The percentages of achieving a PASI75, PASI90, or PASI100 response were assessed. Dermatology Life Quality Index (DLQI) and Itch Visual Analog Scale (VAS) were measured simultaneously. Data about potential safety issues and adverse events were collected.
Results:
A total of 76 patients were included, and 59 (77.6%) were affected by psoriasis localized to the scalp (n = 32), palmoplantar locations (n = 13), or nails (n = 14). The mean PASI score decreased from 16.5 ± 9.8 at baseline to 1.9 ± 1.6 after 16 weeks. Tildrakizumab treatment resulted in the improvement of PSSI (19.9 ± 10.7 to 2.7 ± 4.2), ppPASI (15.4 ± 6.9 to 1.9 ± 2.3), and NAPSI (20.3 ± 16.9 to 7.6 ± 10.8) from baseline to 16 weeks, respectively. DLQI and Itch VAS also showed marked improvement.
Conclusions:
Tildrakizumab is a valuable option for treating difficult-to-treat psoriasis and pruritus, with rapid onset of action.
