A prospective, single-centre, feasibility study evaluating the prevalence of diagnostic clinical imaging features of subclinical enthesitis in patients with moderate to severe plaque psoriasis and the response to skin directed treatment with Ustekinumab

Do the imaging features of subclinical enthesopathy (the earliest change seen in psoriatic arthritis), as measured by peripheral joint ultrasound (USS) and whole body MRI, in patients with moderate-to-severe psoriasis (PASI>10), change when treated for 24 weeks with ustekinumab (at standard dose) for their psoriatic skin disease?
