NCT04835779

Brief Summary

In order to meet the challenge of an unambiguous diagnosis and effective therapy of SFN or the prognosis of susceptibility to the development of SFN, this project aims to create a data basis on which software will be developed during the project. This software should later be able to combine (integrate) quantifiable biometric data collected from the patient (both objectively measured and patient reported parameters) with the results of biological analyses of the patient's own nerve cells from stem cells. We expect that the patient-specific combination and correlation of biometric and biological data can lead to a significant improvement in the diagnosis, prognosis and therapy of chronic pain. The initial data collection required for the development of such a software (Bio2Integrate) will be carried out in three different project parts: Bio2Watch, Bio2Patient and Bio2Cell

  • Test result QST

    Measurement exclusively above the back of the foot that is clinically more severely affected by the SFN, in a balanced row alternately above the right or left foot; one back of the foot as test site per subject

  • Efficiency of reprogramming and differentiation of iPS cells

    Success of differentiation will be measured by flow cytometry at around d10 of differentiation. The percentage of p75 (CD271)-expressing cells will be meassured. The differentiation is defined as successful if more than 30% of cells express p75. Only those differentiations will be used for MEA-Recordings.

Healthy Volunteer

Healthy test person

Healthy Volunteer PREPs

For the pain-evoked potentials (PREPs), 20 additional healthy control subjects are to be included. Four subjects (2 male, 2 female) from each of the age decades 20-29, 30-39, 40-49, 50-59, 60-69.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

SFN Patients (Group A): Patients diagnosed with Small Fibre Neuropathia Healthy Volunteers (Group B): Healthy grown-up Volunteers Patients undergoing chemotherapy (Group C): Patients with imminent initiation of neurotoxic chemotherapy in cancer with solid tumors (preferably of the gastrointestinal tract) with the side-effect of SFN development. There are no plans for follow-up recruitment in case no neuropathy develops after chemo. Healthy Volunteers PREPs (Group D): Healthy grown-up Volunteers. Four subjects (2 male, 2 female) from each of the age decades 20-29, 30-39, 40-49, 50-59, 60-69.

You may qualify if:

  • Group A: Criteria 1-5 Group B: Criteria 2-5 Group C: Criteria 2-6 Group D: Criteria 2-4
  • Small fiber neuropathy (after clinical examination or QST or skin biopsy findings)
  • Legal age
  • Written declaration of consent
  • Persons who are legally competent and mentally capable of following the instructions of the staff
  • Sufficient affinity for independent handling of the technology used (PainWatch incl. the corresponding apps) for daily digital pain recording
  • Imminent initiation of neurotoxic chemotherapy in cancer with solid tumors (preferably of the gastrointestinal tract) There are no plans for follow-up recruitment in case no neuropathy develops after chemo.

You may not qualify if:

  • For all Groups:
  • Persons who are accommodated in an institution by order of the authorities or courts
  • Persons who are in a dependent or employment relationship with the auditor
