Brazil develops a technique to decontaminate transplanted organs



The researchers from the University of Sao Paulo, Brazil, discovered a way to decontaminate the organs of transplantation, thanks to a new method for donors to lightly kill viruses and bacteria.

According to specialists, biophoton therapy, of course, should increase the chances of the available organs and reduce the complications following surgery.

"Currently, there is no decontamination of organ transplants, only burning blood, but the microorganisms are still alive, whether they are excluded from the body or, if there is no other option to avoid death, it is polluted," explains Efe Vanderlei Bagnato, a team of scientists.

The research began in 2015 with the University of Toronto (Canada), which works with the largest transplant program in the world. The Canadians were responsible for the clinical aspect of the project, and the Brazilians were responsible for the development of the technique.

It invested $ 1 million and was responsible for about 10% in Brazil at the Sao Paulo (Fapesp) Research Foundation.

The procedure, first of all, replaces a fluid that keeps you alive by burning the blood of the organ and an external tube connected to the blood.

This liquid is subjected to ultraviolet rays that destroy the microorganisms and their DNA cell membranes.

"Ultraviolet rays are applied externally to kill their cells, but viruses and bacteria captured by liquids," said Bagnate.

On the other hand, the substances that are infrared and infrared light that are capable of selecting viruses and bacteria are put into liquid.

Then, these light frequencies are applied to the body, substances that oxidize the microorganisms and cause the virus to cause hepatitis and AIDS.

According to the scientist, liquid is used more than once, because it is very expensive, which costs 1,500 dollars per liter.

Initial experiments carried out pork lungs, then transplanted humans and eventually tested in patients.

In regards to Marcelo Cypel project, the results were optimal.

"We have already done ten trials with patients, of which two viruses have been removed and eight have been reduced," said Cypel. Bagnato, on the other hand, has said that bacteria are "completely unfocused".

There is a patent registered in Canada and there are companies that are interested in manufacturing this technique equipment. In Brazil, the goal is to test the renal and liver program with the two most transplanted organs in the South American country.

Scientists believe that in the future the use of organs will be improved, reducing costs and increasing waiting time and expanding other transplants, such as the heart or pancreas.

"Today, it's a face transplant, face, but it is very expensive, as a lung transplant, for example, costs around $ 160,000, in Brazil, dozens of dollars a year, but how many people do they need?" asked Bagnat.

Another progress that Bagnato is projecting in the future is to decontaminate organisms in people who can effectively cure illnesses.

In 2018, 20,000 transplants were needed in Brazil, for example, kidneys, hearts, liver and lungs, but only 8,500 were made. The recruitment line is more than 30,000 people, according to the Brazilian Transplant Association.
