Quantitative Ultrasound of the Enthesis in Fibromyalgia & Psoriatic

Status Recruiting

Clinical Trial Summary

This prospective, cross-sectional, observational study will include subjects with fibromyalgia (FM), psoriatic arthritis (PsA) and asymptomatic controls. Participants will undergo a research ultrasound (US) exam of the enthesis of the Achilles' tendon, the medial collateral ligament at the femoral epicondyle and the common extensor tendon at lateral epicondyle of the elbow in resting conditions. The research US exam will consist of shear wave elastography (SWE) and radiofrequency (RF) data acquisitions. SWE technology will allow quantification of the shear wave speed (SWS) reporting the elastic stiffness of the tissues under investigation. RF data will be used to estimate quantitative ultrasound (QUS) parameters characterizing the mean intensity μ (akin to B-mode echogenicity), acoustic inhomogeneity (1/alpha), and structural spatial organization of echoes (κ) in the tissue.

Clinical Trial Description

In this prospective, cross-sectional, observational study consecutive eligible subjects with FM, PsA, and a group of age- and sex-matched asymptomatic volunteers will undergo a research US examination of the dominant Achilles' tendon, knee medial collateral ligament and common extensor tendon of the elbow. Two operators under the supervision of a musculoskeletal radiologist will perform the US exam. B-mode and Power Doppler ultrasound of each tendon and ligament will be performed for morphological characterization. Then, shear wave elastography (SWE) and radiofrequency (RF) will be acquired. The shear wave speed (SWS) will be measured in the longitudinal plane using shear wave measurements. These features will be compared between groups. The HDK parameters (μ, 1/alpha, κ) will be computed offline, using RF sequences recorded in the longitudinal plane. Demographic features (participant age, sex, body mass index), the Leeds Enthesis Index (LEI) score assessed by the referring clinicians, and the self-administered Health Assessment Questionnaire (HAQ), Brief Pain Inventory (PBI) and Fibromyalgia Impact Questionnaire (FIQ) scores will be available for multivariate analyses. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
