Biologically speaking, cleaning up bacteria and virus is our immune system’s job description. But, when the body wears out, these micro bodies tend to hang around. In chronic or medically sensitive situations, such as organ transplants, it is vital to maintain the body’s defense systems. In a first of its kind experiment, researchers applied biophotonic therapy to decontaminate organs before transplanting them.
Biophotonic technique is a process in which the patient’s blood stream is exposed to ultraviolet (UV) irradiation.
Unmet Need to Increase Number of Transplants Drives Experiment
Researchers from University of São Paulo (USP), Brazil partnered with scientists at the University of Toronto, Canada for this study.
University of Toronto runs the largest lung transplantation program globally, with nearly 200 surgeries performed in 2018. The scientists aim at increasing this number, by containing the risk of infection. Consequently, the rate of organ transfer and efficiency will increase.
Biophotonic Therapy Combine to Make Perfusion More Effective
The study, published in the journal Nature Communications states the use of light therapies for eliminating infections like hepatitis B. The scientists use ultraviolet and red light irradiation. The transplant organ, in this case the lungs, are first processed on. This process, called perfusion, involves circulation of a preservation liquid through the organ.
This process, combined with biophotonic technique, wherein red light with a 660 nm wavelength is irradiate on the lungs. At the same time, ultraviolet light of 254 nm wavelength decontaminates the transplant organ. The combination of biophotonic techniques makes the perfusion process more efficient. Consequently, the entire organ transplant process will become low risk, faster, and successful.
