Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Nearly 30% of patients with cutaneous psoriasis (PsO) developed psoriatic arthritis (PsA). Among these patients 20 % will have severe destructive arthritis. The risk of developing PsA is significantly higher in patients with nail involvement (OR = 2.24; 95% CI \[1.26-3.98\]). The risk is particularly high for the peripheral form of PsA and onycholysis (OR=2.80; 95% CI \[1.34-5.85\]).

Thus the investigators wanted to test the hypothesis that onycholysis, in patients without PsA, is a potential clinical marker of subclinical distal enthesopathy and, by extension, of bone micro-structural alterations.

Patients and Methods

The investigators will recruit 4 groups of subjects:

1. Patients with peripheral PsA,
2. Patients with psoriatic nail onycholysis,
3. Patients with PsO only
4. Healthy match control subjects. The investigators will assess the presence of enthesopathy by ultrasonography and bone structural damages (by HR-pQCT) in all subjects at baseline and 4 years.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with peripheral PsA

HR-pQCT High resolution peripheral quantitative CT-scan

Intervention Type RADIATION

HR-pQCT is a powerful device providing low dose irradiation already used in bone field.

It is a high resolution tool (voxel size=82µm) that the investigators adapted to look after the distal joint involved by onycholysis. An anteroposterior scout view is used to define the region of interest (ROI), which spanned from the top of the distal phalange to the distal part of the intermediate phalange in order to contain the distal joint of the target finger. Images are then analysed for erosions, osteophytes and volumetric bone mineral density.
