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.

Conditions

  • Systemic Autoimmune Pathologies
  • Unexplained Pain Syndrome

Interventions

OTHER

SUDOSCAN and EMG (electromyogram)

The participants are evaluated clinically by a neurologist with evaluation by DN4 questionnaire, treatments and comorbidities (alcohol consumption, diabetes, etc.). They undergo from exploration by SUDOSCAN according to the already established methodology and an EMG
