  • A pioneering method using a donor skin patch to rapidly detect organ rejection has shown promising results in lung transplant patients.
  • The Sentinel trial involves grafting a small skin patch from the organ donor onto the patient's forearm, acting as an early warning system for rejection.
  • Scientists believe skin rejects earlier and more visibly than other organs, allowing medics to treat rejection as soon as a rash appears, significantly reducing the risk of permanent damage.
  • Darren White, a lung transplant patient, experienced a purple rash on his skin patch three months post-surgery, leading to early detection of mild rejection and successful treatment with steroids.
  • The Sentinel trial, set to run until 2027 and recruit 152 patients, aims to revolutionise lung transplant care by providing a more effective way to monitor and manage organ rejection.
