Outcome following a short period of adalimumab dose escalation as rescue therapy in psoriatic patients.

BACKGROUND: Advances in biologic treatments have led to a new therapeutic frontier for moderate-to-severe psoriasis. Nevertheless, the efficacy of anti-TNFalpha decreases with time, requiring adjustments to maintain valuable Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) responses. OBJECTIVES: To evaluate the efficacy and safety of adalimumab dose escalation (40 mg, subcutaneous, once a week for 24 weeks) in psoriatic adult patients with secondary loss of response (PASI >/=50 to /=75 and DLQI >/=5). MATERIALS AND METHODS: A multicentre, observational study involving different Italian third-level referral centres for psoriasis enrolled a total of 64 adult patients with moderate-to-severe psoriasis who were treated with adalimumab and experienced a secondary loss of response. Primary end-points were PASI> 75 or PASI >/=50 to
