Kyoto University Hospital announced that it has performed the world's first living-donor lung transplant to transplant the lungs of people with different blood types, which have been considered difficult to transplant, to patients with severe lung diseases.

The hospital says, "Many patients have died because their blood types do not match their families, but this success will be a new light to save patients."

This was announced by the Kyoto University Hospital and the Japan Society for Transplantation at an online press conference on the 12th.

The transplant was given to a teenage female patient with blood type O living in the Kanto region, and in February, a part of the lungs donated by a B-type father and an O-type mother were transplanted. I did.



The woman suffered from an intractable lung disease about three years ago, and by September last year her condition had deteriorated to the point where she needed a ventilator, but after surgery she recovered steadily to the point where she could walk on her own.11 It means that he was discharged on the day.



Living-donor lung transplants with different blood types are prone to rejection and infections caused by injecting outside air into the lungs, so it has been considered difficult except for some combinations of blood types.



This time, the hospital performed the world's first transplant by administering an immunosuppressive drug to the patient in advance and then removing the antibody that reacts with type B.



Professor Hiroshi Date of CPR said, "Many patients have died because their blood types do not match their families. The success of this transplant is a new way to save patients who cannot wait for a brain-dead transplant and cannot do a living-donor lung transplant. It will be light. "
