[Translated article] Perceived quality of life in patients with psoriasis treated with interleukin 17 or 23 inhibitors.

Objective: To determine the effectiveness in terms of quality of life perceived by adult patients with moderate/severe plaque psoriasis treated with interleukin 17 or 23 inhibitors and to identify associated factors.

Method: Cross-sectional observational study including adult patients diagnosed with moderate/severe plaque psoriasis treated with interleukin 17 or 23 inhibitors for at least 12 or 16 weeks in follow-up, respectively.

Results: Forty-one patients were included: 65% male, median age 54 years (SD=13). The included patients were treated with ixekizumab 35%, guselkumab 25%, secukinumab 17.5%, brodalumab 15%, and risankizumab 7.5%. Psoariasis area severity index (PASI) reduction was 94.6% (RIC 76.8-100%), DLQI of 1 (RIC 0-2.75), DLQI≤1 60%. The most affected health dimensions were symptoms and perceptions (57.5%), activities of daily living (27.5%), and discomfort caused with treatment (17.5%). No association was found between DLQI score <1 and demographic, comorbidities, and treatment-related variables. The median PASI reduction in patients with DLQI<1 was superior to patients with DLQI>1 (100% vs 90.2%, p=.025).

Conclusions: Patients with moderate/severe plaque psoriasis treated with interleukin 17 or 23 inhibitors achieve adequate therapeutic targets achieving the target set according to clinical practice guideline recommendations (score ≤1 on the DLQI questionnaire and 90-100% reduction in the PASI index) and in accordance with the results of recent meta-analyses and real-life studies. A greater reduction of the PASI index is observed in the group reaching the quality of life target, there being the possibility of using patient-reported outcomes in the evaluation of treatment effectiveness.
