south DANish PAIN research Biobank (DANPAIN Biobank)
The aim of this biobank, containing blood and CSF from patients with chronic pain and healthy volunteers, is to contribute to a greater understanding of pathological factors involved in chronic pain and identify possible biomarkers.
The cause of most chronic pain conditions is unclear. The consequence is that diagnostics and treatment is often unsatisfactory.
Recent evidence suggests that many chronic pain conditions are part of the same "Central Sensitivity Syndrome" caused by neuroinflammatory activation in the spinal cord, causing central hypersensitivity and pain.
The purpose of the project is to examine for neuroinflammatory biomarkers in the Cerebrospinal Fluid and blood, to identify a possible central neurinflammatory process as part of the causality for chronic pain.
Description of the cohort
The biobank includes blod and cerebral spinal fluid from:
200 consecutive patients from a multidisciplinary pain center with cronic complex pain syndromes
81 patients with chronic pain localized to the hip or knee, caused by osteoarthritis.
70 pain free volunteers.
Data and biological material
Samples from cerebrospinal fluid and blood, demographic data, questionnaire data on pain, functional level, sleep disturbance, anxiety and depression.
Quantitative sensory tests have been conducted on group 1 (200 patients from a multidisciplinary pain center) and group 3 (healthy volunteers).
