Trial summary

Scleroderma and other rheumatologic conditions can affect the skin. Scleroderma in particular involves skin thickening and hardening. Currently, looking at the degree that the skin is affected by scleroderma is measured based on a combination of a physical exam and a skin biopsy. Read more about this study

About this study

Official title: Acoustic Radiation Force Impulse/Shear Wave Velocity Imaging of the Skin in Scleroderma and Other Rheumatologic Diseases

Scleroderma and other rheumatologic conditions can affect the skin. Scleroderma in particular involves skin thickening and hardening.

Currently, looking at the degree that the skin is affected by scleroderma is measured based on a combination of a physical exam and a skin biopsy.

The researchers propose to measure skin hardness using ultrasound imaging of elasticity. They will use a technique using acoustic radiation force impulse/shear wave velocity imaging , known as ARFI/SVI).

The investigators hypothesize that ARFI/SVI may be able to distinguish between normal skin and skin affected by scleroderma.. This tool may also help to quantify the amount of fibrosis in the skin.

This type of radiologic biomarker could be used to help confirm the diagnosis of scleroderma.

Read the detailed description

Scleroderma as well as numerous other rheumatologic conditions can affect the skin. Scleroderma in particular causes skin thickening and hardening.

Currently, evaluation of degree to which skin is affected by scleroderma is measured by a combination of a physical exam and skin biopsy results.

The investigators propose to measure skin hardness using ultrasound elasticity imaging, in the form of acoustic radiation force impulse/shear wave velocity imaging (ARFI/SVI).

The investigators hypothesize that ARFI/SVI may be able to distinguish normal skin from skin affected by scleroderma (and other rheumatologic conditions). And, this ultrasound technique might measure the amount of fibrosis in the dermis (skin).

Such a radiologic biomarker could be used to help confirm the diagnosis of scleroderma. In addition, it may be usable for following patients over time and measuring their response to therapy and progression of disease.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ARFI-SVI UltrasoundDevice

    Ultrasound imaging of arm and leg lasting approximately 5-10 minutes. Participants will also undergo durometer scoring on the forearm and thigh as part of the study. This lasts approximately 5-10 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Skin Stiffness

    Skin stiffness was measured from the forearm and thigh of patients with scleroderma using ultrasound shear wave velocity imaging. Shear wave velocity is measured in meters per second (m/s).

    Measured: Cross-sectional study, 1 visit, <1 hr

Secondary outcomes (6)
  1. Mean Skin Stiffness as Measured by Durometer Scoring

    Durometer scoring of skin stiffness in two groups of patients (controls and scleroderma). Durometer measurements are expressed in standardized international durometer units ranging from 0 to 100 where 100 is harder (worse outcome) The Rex Gauge model DD-3 was used. For further reference see Arthritis and Rheumatism (Arthritis Care \& Research) Vol. 55. No. 4, August 15, 2006, pp. 603-609. DOI 10.1002/art.22093.

    Measured: Cross-sectional study, 1 visit, <1 hr

  2. Linear Relationship Between Ultrasound Skin Stiffness and Durometer

    Pearson correlation assesses the linear relationship between Ultrasound skin stiffness measurements and Durometer scoring of skin stiffness.

    Data was combined for scleroderma and control subjects to assess the relationship and association across a broad range of skin conditions.

    Measured: Cross-sectional study, 1 visit, <1 hr

  3. Mean Landmark Scores

    Mean Landmark scores are on a scale of 0 to 3, 0 = normal and 3 =marked skin hardening.

    Measured: Cross-sectional study, 1 visit, <1 hr

  4. Linear Relationship Between Ultrasound Skin Stiffness and Landmark

    Pearson correlation assesses the linear relationship between ultrasound skin stiffness and subjective skin scoring (Landmark) of skin stiffness in all patients (controls plus scleroderma). Data was combined for scleroderma and control subjects to assess the relationship and association across a broad range of skin conditions.

    Measured: Cross-sectional study, 1 visit, <1 hr

  5. MRSS Scores for Scleroderma Participants.

    MRSS scores exist on a scale from 0 to 51 based on scores of 0 to 3 measured in 17 locations on the body, where 0 represents overall healthy skin and 51 would be the worst outcome in all 17 locations.

    MRSS measures are not taken on healthy participants.

    Measured: Cross-sectional study, 1 visit, <1 hr

  6. Linear Relationship Between Ultrasound Skin Stiffness and MRSS

    Pearson correlation assesses the linear relationships between ultrasound skin stiffness and subjective skin scoring (MRSS) of skin stiffness. MRSS is the Modified Rodnan Score. Skin thickness is measured by clinical palpation using a 0-3 scale. 0 = normal skin; 1 = mild thickness; 2 = moderate thickness; 3 = severe thickness with inability to pinch the skin into a fold.

    Because MRSS measurements were not taken for healthy participants, no correlations are provided for them. Therefore, the correlations are based on a skin stiffness and skin scoring solely for scleroderma participants.

    Measured: Cross-sectional study, 1 visit, <1 hr

Questions about this trial

What is this clinical trial studying?

An observational study of Scleroderma, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Skin Stiffness (time frame: Cross-sectional study, 1 visit, <1 hr). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jul 2019.
