NCT02208206

Brief Summary

The purpose of this study is to analyze associations between symptoms and specific markers in the blood in patients suffering from neuropathic pain linked to diseases of different origin. Such markers could be utilized in the future for precise diagnosis of neuropathic pain and might lead to targeted pain treatment.

Outcome Measures

Primary Outcomes (1)

  • Analysis of gene expression

    Investigation of associations between phenotypic and genotypic data. Patients with chronic painful and non-painful neuropathy will be phenotyped in detail using validated questionnaires related to pain (Brief Pain Inventory and Numeric Rating Scale), mental health (Pain Catastrophizing Scale and Hospital Anxiety and Depression Rating Scale), personality (Ten-Item Personality Inventory) and quality of life (36-Item Short Form Health Survey and Insomnia Severity Index). Optional, a set of neuropsychological/cognitive tests and quantitative sensory testing (QST) will be performed. DNA will be isolated from patients' blood samples and analyzed for genetic variants which might have an effect on the development of neuropathic pain. Once, phenotypic and genotypic data are available they will be associated with each other with the goal to find genetic variants tied to pain phenotypes and which might serve as novel DNA biomarkers for neuropathic pain.
