Hope for burns victims as researchers pilot revolutionary new dressing

The disabling disfigurement suffered by many burns victims could be consigned to history thanks to a revolutionary new dressing developed by a team of Birmingham scientists.

Researchers at the NIHR Surgical Reconstruction and Microbiology Research Centre (SRMRC) and the University of Birmingham have created a biomembrane using the molecule Decorin which they hope will prevent scarring in injured tissue.

The dressing will now be tested on burns patients at Queen Elizabeth Hospital Birmingham (QEHB), where the NIHR SRMRC is based, in a three-year clinical trial after the team were awarded a £1.6 million grant from the Wellcome Trust to fund further research.

Decorin is a synthetic version of a molecule which occurs naturally in the body – albeit in tiny amounts – most notably in the amniotic membrane.

Professor Ann Logan, who specialises in molecular neuroscience, identified it as a possible agent in anti-scarring dressings through her work looking at how to repair injured brain and spinal cord tissue.

Professor Liam Grover, a biomaterials expert, then created a membrane wound dressing which incorporates the synthetic molecule and can be produced in sheets big enough to cover large areas of the body.

The dressing can be freeze dried, allowing it to be stored and manipulated by surgeons without damage, before being rehydrated with saline ahead of use.

This novel property means that it could even be used by soldiers on the battlefield, keeping a dressing in their kit with a sachet of saline for use in an emergency.

Researchers will now work with burns consultant Mr Naiem Moiemen at QEHB to trial the dressing on patients, through the Healing Foundation Centre for Burns Research, a partnership involving the hospital and university.
If successful it will be developed to be used in other tissues where scars can be problematic, such as in the eye or after neurosurgery.

Currently, the main priority for doctors treating burns is to prevent dehydration and infection, rather than scarring – but scars, and the contractures they create, are unsightly and can permanently hamper movement. Decorin prevents the development of contractures, allowing the wound to be closed with normal tissue rather than scar tissue.

Professor Logan said: “When the tissues are damaged, it is a race between scarring that quickly closes the wound with a ‘patch’ and regenerative healing that reconstructs more normal tissue – therefore our strategy is to use Decorin to slow down the scarring process.

“We don’t necessarily want to stop scarring per se, but promote the speed of regenerative healing before the skin scars. It’s about giving skin the time to heal naturally before the scarring takes over.
“There’s no treatment for these problem scars at the moment, so if we can prevent those scars, it will be a huge benefit to the patients.”

Professor Grover, from the University of Birmingham's School of Chemical Engineering, added: “This clinical problem, of slowing down the scarring to allow the skin to heal, was brought to me to see if I could create a robust burns dressing that could deliver drugs like Decorin without falling apart in the challenging wound environment.

“The trick is to ensure the drugs don’t affect the properties of the dressing and the properties of the dressing don’t affect the activity of the drugs.

“As materials scientists we design things to be used in everyday life, and I feel very proud that we are going to be able to use this to help people who have been injured.”

Life Sciences Minister George Freeman MP said: “Burns can be devastating injuries often with huge impact on victim’s lives, so it is great to see such a revolutionary treatment developed right here in the UK.

“Discoveries such as this are the reason we invest £1 billion a year through the National Institute of Health Research, helping to reinforce the UK’s reputation as a world-leader in health research.”

The National Institute for Health Research (NIHR)

  • The NIHR is funded by the Department of Health to improve the health and wealth of the nation through research. 
  • Since its establishment in April 2006, the NIHR has transformed research in the NHS. It has increased the volume of applied health research for the benefit of patients and the public, driven faster translation of basic science discoveries into tangible benefits for patients and the economy, and developed and supported the people who conduct and contribute to applied health research. 
  • The NIHR plays a key role in the Government’s strategy for economic growth, attracting investment by the life-sciences industries through its world-class infrastructure for health research. 
  • Together, the NIHR people, programmes, centres of excellence and systems represent the most integrated health research system in the world. For further information, visit the NIHR website 

The NIHR Surgical Reconstruction and Microbiology Research Centre

  • The NIHR SRMRC is a national centre for trauma research, transferring innovation used in the treatment of injured military personnel to improve outcomes for all patients.
  • It brings together the pioneering advances in surgery and infection control made by military and civilian scientists and medics working together.
  • Launched in January 2011, the national trauma research centre will share its discoveries with the wider NHS to support delivery of excellence in a complex area of acute care.
  • Based at the Queen Elizabeth Hospital Birmingham (QEHB), the centre harnesses expertise from the Ministry of Defence (MoD), University of Birmingham (UoB) and QEHB and has been funded over five years with a total £15 million investment (£5 million QEHB and UoB; £5 million MoD; £5 million DH).
