Ehlers-Danlos Syndrome (EDS) is an inherited disease of collagen, found in connective tissues, such as skin. EDS patients suffer from joint and skin problems (skin hyperextensibility, joint hypermobility) along with a large range of other disorders, including, delayed wound healing with atrophic scarring, easy bruising, tissue fragility, gastrointestinal and gum problems. There are many different types of EDS, with different mechanisms of action, and not all of these are well understood. This study will used advanced microscopy techniques called atomic force microscopy (AFM) and scanning electron microscopy (SEM) to analyse the changes in collagen as a result of EDS, compared to normal collagen. These changes will be viewed at the micron and nanoscale level (between 1,000 to 100,000 x magnification), and will focus on the differences in collagen construction through a process called cross-linking. These changes could potentially help clinicians understand the root cause of EDS symptoms, and provide a deeper knowledge of cross-linking disorders in collagen. Increasing our knowledge of how collagen is affected in EDS patients, may lead to improved treatment options for patients.
Study Type
OBSERVATIONAL
Enrollment
35
Patients will have the surgery they require for their treatment. During surgery, debrided tissues will be retained for research. No treatment plans will be altered for this research.

Histological changes in EDS compared with healthy collagen using light microscopy after staining
Light microscopy will be qualitatively used to observe colour changes after staining between healthy and EDS collagen
Time frame: 1-5 years
Collagen morphological changes in EDS compared with healthy collagen using AFM and SEM
AFM and SEM will be used to qualitatively observe changes in orientation in collagen.
Time frame: 1-5 years
Collagen topographical changes in EDS compared with healthy collagen using AFM and SEM
AFM and SEM will be used to observe changes in length, width and height of healthy and EDS collagen, as well as D-band length. This will be measured in meters (nm).
Time frame: 1-5 years
Collagen Young's modulus changes in EDS compared with healthy collagen using AFM
AFM will be used to calculate the Young's (elastic) modulus of the EDS and healthy collagen. This will be measured in Pascals (GPa).
Time frame: 1-5 years
Collagen nanoscale adhesion changes in EDS compared with healthy collagen using AFM
AFM will be used to calculate the changes in adhesion force of the EDS and healthy collagen. This will be measured in Newtons (nN). Quantitative outcomes: changes in Young's (elastic) modulus, changes in adhesion force, changes in single molecule pulling force
Time frame: 1-5 years
Collagen nanoscale single molecule pulling force in EDS compared with healthy collagen using AFM
AFM will be used to calculate the changes in pulling force of single molecules of EDS and healthy collagen. This will be measured in Newtons (nN).
Time frame: 1-5 years
