For the transplant, consumption of peanuts by the donor can be fatal when he is allergic to nuts.
People who consume large amounts of peanuts may not be suitable for donors because of the risk of allergic reactions in the recipient, according to a new study published in the medical journal New England.
A 6-year-old boy suffering from leukemia underwent unsuccessful surgery on donor platelets by consuming peanuts. The recipient has an allergic attack characterized by severe rash and swelling of the skin. The boy's blood pressure drops sharply and breathing becomes difficult, which requires the intervention of doctors who inject adrenaline to save the child, according to the scientific report.
Doctors determined the cause of the allergic reaction with the help of the boy's parents, who reported that he had suffered a similar situation at the age of one after consuming a peanut product. After receiving the information, the doctors followed the anamnesis of the five blood donors and found that three of them had consumed peanuts the night before the blood donation.
An interesting case raises the question of whether allergens can be transmitted from one person to another through blood . At this stage, cases of allergic reactions caused by blood are extremely rare, said Dr. John Jacobs of the University of Nijmegen, the Netherlands.
The main allergen in peanuts, Ara h2, is extremely resistant to the digestive system and can accumulate in the blood serum, where it stays for up to 24 hours after consumption, the researchers found.
Experts advise to pay more attention not only to the health condition, but also to the diet of the donors, which, although quite time consuming, due to the large number of donors, can prevent a case like this.
