Summary
This trial aims to test the safety and effectiveness of injecting STS directly into calcinosis lesions in patients with certain autoimmune diseases. The injection process will be guided by ultrasound, and the effects on lesion
Who is the study for?
This trial is for individuals with conditions like systemic sclerosis, lupus, dermatomyositis, and other connective tissue diseases who have calcinosis. Participants should have symptoms or lesions that can be measured. Specific eligibility criteria are not provided but typically include age limits and health status requirements.
What is being tested?
The study tests the safety and effectiveness of Sodium Thiosulfate (STS) injections directly into calcified lesions in patients with certain connective tissue disorders. The size of the lesion will be monitored by ultrasound, and patient feedback on symptom relief will also be recorded.
What are the potential side effects?
While specific side effects are not listed here, intralesional STS injections may cause local reactions such as pain or swelling at the injection site, potential skin changes, or allergic reactions.
