Skin Patch Trial Promises Better Outcomes by Alerting Doctors of Organ Rejection

Doctors hope to detect rejection in its early stages by transplanting donor skin patches onto the forearms of lung transplant recipients

Scientists at the University of Oxford, in collaboration with NHS Blood and Transplant, are launching a new trial with the goal of improving lung transplant survival rates. Researchers want to improve organ failure diagnosis and management by implementing innovative skin patches,' potentially changing the landscape of transplant therapy.

This trial focuses on using the skin's unique features as an early indicator of organ rejection. Skin, which is very sensitive and susceptible to rejection earlier than other organs, provides an ideal platform to determine transplant survival. Doctors hope to detect rejection in its early stages by transplanting donor skin patches onto the forearms of lung transplant recipients, allowing for timely intervention to avoid further difficulties.

The skin patches, which measure 10cm by 3cm, will be surgically placed during the lung transplant surgery to serve as a visual warning system for both patients and healthcare personnel. If a rash appears on the skin patch, it acts as a strong warning of impending organ rejection, requiring rapid action to save the transplanted

The significance of this trial goes beyond detection; researchers believe that the skin patches will provide vital insights into the surgical removal of the transplanted organ. By closely monitoring the skin patches, doctors may assess the organ's performance and make informed therapy adjustments, potentially minimizing the need for frequent hospital visits and intrusive tests.

Initial trials of intestine transplants have given promising outcomes, with skin showing signals of rejection days before other clinical indicators. Furthermore, patients who got skin flaps from donors had considerably decreased rates of organ rejection, demonstrating the potential significance of this new technique.

Fiona Ballantyne, a prospective trial participant awaiting a lung transplant, highlights the technology's transformative potential for transplant recipients. The idea of being able to monitor organ health via a simple visual signal provides new hope and confidence to those facing the terrifying idea of transplantation.

Adam Alderson, a multi-organ transplant recipient, praises skin grafts' ability to detect signals of rejection early on. Alderson sees skin patches as a critical tool in preventing rejection episodes, similar to an important warning light in a vehicle.

It’s a really comforting thing to have - I feel safer knowing that I have a tool available to tell if something is going wrong before it becomes too serious. It’s almost like an oil warning light on your car.
Adam Alderson, Patient

Chief investigator Henk Giele emphasizes the significance of this experiment, particularly for lung transplants, which have a higher rejection rate. The skin patches' visible warning system represents a significant advancement in transplant medicine, providing unprecedented opportunities for early intervention and better patient outcomes.

A visible warning system like this is crucial for all transplants, but especially those with higher rejection rates.

Emma Lawson, research lead at NHS Blood and Transplant, expresses gratitude for the collaboration and emphasizes the organization's commitment to supporting new research projects focused on improving transplant success rates.

The study is being funded by a Medical Research Council (MRC) and National Institute for Health and Care Research (NIHR) partnership.

As the Sentinel study advances over the following three years, it brings in a new age of organ transplantation, with early identification and intervention becoming the foundation of treatment. Skin patches emerge as an indicator of hope in the attempt for better transplant outcomes.
