Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Psoriatic Arthritis
Subjects newly diagnosed with psoriatic arthritis (< 5 years), confirmed by a rheumatologist and fulfilling the CASPAR criteria.
|
High quality ultrasound scanners and high-resolution transducers, will be used to scan 16 joints sites for each subject.
Ultrasound had excellent spatial resolution, making it an highly efficient, non-invasive tool for the assessment on enthesitis, which is an early feature of psoriatic arthritis.
It is an affordable and accessible tool that is widely used in rheumatology practice.
|
Psoriasis without musculoskeletal symptoms
Patients with dermatologist confirmed psoriasis, without any history of Psoriatic Arthritis, and musculoskeletal symptoms.
|
High quality ultrasound scanners and high-resolution transducers, will be used to scan 16 joints sites for each subject.
Ultrasound had excellent spatial resolution, making it an highly efficient, non-invasive tool for the assessment on enthesitis, which is an early feature of psoriatic arthritis.
It is an affordable and accessible tool that is widely used in rheumatology practice.
|
Non-Inflammatory Rheumatic conditions
Patients with non-inflammatory rheumatic conditions such as osteoarthritis, non-specific back pain, soft tissue rheumatism, degenerative tendinopathy and fibromyalgia.
Patients with present or past history of psoriasis, psoriatic arthritis, known or suspected rheumatic inflammatory conditions (e.g.
rheumatoid arthritis, spondyloarthritis and gout), and/or inflammatory bowel disease will be excluded.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
DUET scoring system for early diagnosis of PsA
Time Frame: From beginning to end of physical & ultrasound assessment, up to 1.5 hours
|
To derive the DUET scoring system for distinguishing PsA from non-inflammatory disease using musculoskeletal ultrasound.
The investigators will report the optimal set of weighted parameters and their performance measures (area under the curve, suggested cut-off points, sensitivity, and specificity).
|
From beginning to end of physical & ultrasound assessment, up to 1.5 hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess the construct validity of the new DUET scoring system
Time Frame: From beginning to end of physical & ultrasound assessment, up to 1.5 hours
|
Construct validity of the newly derived DUET scoring system will evaluate its correlation with clinical measures of disease activity (e.g. total enthesitis count, joint count) and patient reported outcomes. The investigators will evaluate the agreement between central and local readers using the new scoring system to evaluate its reliability among local readers using intra-class correlation coefficient. |
From beginning to end of physical & ultrasound assessment, up to 1.5 hours
