Genetic Predisposition for Chronic Non-specific Low Back Pain (Backgene)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02955407
Recruitment Status : Completed
First Posted : November 4, 2016
Last Update Posted : January 23, 2019

Balgrist University Hospital

Brief Summary:
Patients with inflammatory back pain were shown to differ from healthy controls in genotype of the Angiotensin-converting enzyme (ACE), which regulates vasoconstriction/-dilatation. The aim of this study is to investigate whether genetic reduction of muscle perfusion might be a pathophysiological pathway of how genes influence chronic non-specific low back pain (LBP).

Condition or disease Intervention/treatment
Low Back Pain Other: no intervention

Detailed Description:

The following genes will be investigated:

  • Insertions-/deletions-polymorphism of the angiotensin-converting enzyme (ACE-I/D gene polymorphism; 3 genotypes: ACE-II, ACE-ID, ACE-DD).
  • Anti-adhesive extracellular matrix protein Tenascin-C: gene polymorphism rs2104772

The goals of this study are to investigate whether these genotypes correlate with 1) endurance of back muscles, 2) comorbidities such as asthma and diabetes and 3) the risk for LBP as assessed by a LBP-classification tool.
