Objective: The purpose of this study is to describe the subclinical ultrasound findings in nails and distal interphalangeal joints in psoriatic patients. Methods: It was a descriptive observational study. Three study groups were described: patients presenting cutaneous and nail psoriasis (CNP), psoriatic patients without psoriatic nails (CP), and healthy nails (HN). Ultrasound measurements of the nail bed and nail plate thickness, resistance index in nail bed arteries, osteotendinous changes, ungual plate margins and undulations were performed. Results: 31 subjects were analyzed: 11 cutaneous and nail psoriasis, 10 cutaneous and 10 healthy nails. The median thickness of the nail bed was higher amongst the groups with psoriasis (CNP 1.9mm IQR [1.6-2.2], CP 1.9mm IQR [1.7-2.1]) compared to HN (1.7mm IQR [1.5-1.9]), (p<0.001). The nail plate thickness had significant differences between groups, (p<0.001) (CNP 0.7 mm IQR [0.7-0.9], CP 0.8mm [0.7-0.9], HI 0.6mm [0.6-0.7]). Conclusions: In psoriatic patients, ultrasonography of the nail unit provides subclinical information that is not available from the physical examination.
