A man in Germany, suffered an extreme allergic reaction to kiwi after receiving a bone marrow transplant from his sister who is allergic to the fruit, doctors said.

Dr. Natalie Garzorz of the Department of Dermatology and Allergy at the Technical University of Munich, said that the 46-year-old man suffered from leukemia and got the bone marrow from his sister as part of his treatment plan.

The patient was doing well until he decided to eat kiwi a few weeks after the procedure. He developed an oral reaction, including swelling in the mouth and throat, for the first time in his life.

He had difficulty breathing, but he survived the attack. The man’s sister is also allergic to kiwi, but the patient did not
know that the allergens from his sister will transfer to his body.

Scientists isolated the man’s cells that reacted to the kiwi.

Using a process called FISH, the scientist were able to determine that the cells sensitive to kiwi originated entirely from his sister’s donated bone marrow.
