Nail involvement as a negative prognostic factor in biological therapy for psoriasis: a retrospective study

Abstract

Patients with NP reach PASI 75 more slowly than patients without NP. Clinicians should therefore consider that treatment with a biological agent may require a longer period before reaching a satisfying therapeutical goal. Nevertheless, adalimumab, infliximab, ustekinumab and etanercept demonstrated their equal effectiveness in reducing the NAPSI score.
