Detection of Small Fiber Neuropathies by the Non-invasive SUDOSCAN Method During Chronic Autoimmune Pathologies and / or Unexplained Pain Syndromes

France139 participantsStarted 2017-07-06

Plain-language summary

Very few studies have evaluated the prevalence of small fiber neuropathy (SFN) during pathologies that may be responsible for small fibers damage. SUDOSCAN is a new rapid (2 minutes), automated, reproducible and non-invasive technology to assess small fiber neuropathy by sweat function. With quantitative and reproducible results, SUDOSCAN allows physicians to early detect and follow-up peripheral neuropathy to monitor disease progression and assess treatment efficacy for a better patient management. SUDOSCAN® could allow the identification of SFN in painful patients apart from another pathology already diagnosed responsible for SFN. The purpose of the study SUDOCU is to assess the prevalence of small fiber neuropathies (SFN) in patients with systemic autoimmune pathologies or unexplained pain syndrome.

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.
