Photoacoustic/Ultrasound Imaging in Patients of Dermatomyositis With Calcinosis Cutis: Characteristic Findings and Treatment Response Evaluation
China100 participantsStarted 2024-01-01
Plain-language summary
Photoacoustic imaging (PAI) is an emerging biomedical modality that integrates the advantages of optical contrast and ultrasound imaging depth. Capable of providing morphological, functional, and molecular information, PAI shows significant promise for visualizing human superficial tissue. The goal of this clinical trial is to build a PAI evaluation method for DM skin lesions, explore its application value in assessing DM disease severity and evaluation of treatment response. The main questions it aims to answer are:
1. How to establish a non-invasive PA/US imaging evaluation method for DM skin lesions?
2. Can PAI precisely assess DM disease severity?
3. Can PAI systems predict the treatment response in DM with calcinosis cutis? Participants will receive regular PA/US imaging examinations during five stages of treatment (before treatment, 3 months, 6 months, 9 months and 12 months). And the effectiveness of PA/US in treatment response for DM at different time points will be evaluated.

Inclusion Criteria:
* All patients fulfilled the 2017 EULAR/ACR classification criteria for idiopathic inflammatory myositis. Of the adult DM patients enrolled, those were found to have calcinosis and were subsequently included in our analysis.
* Among enrollees with idiopathic inflammatory myositis, patients with pathognomonic skin rashes were subclassified as DM or amyopathic DM patients based on the 2017 EULAR/ACR classification tree.
* For patients without pathognomonic skin manifestations, DM was defined according to muscle biopsy.
* Patients with amyopathic DM were grouped with DM patients.
* Calcinosis diagnosis was based on clinical examination findings.
Exclusion Criteria:
* Patients whose age at disease onset was \<18 years and those with overlap syndrome and/or IBM were excluded.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
