Why Blood Transfusions from Women May Be Risky for Men
Science & Tech / /
It is established practice that the sex of a blood donor is considered irrelevant when transfusing blood, but a recent study is throwing new concerns, which suggest that blood transfusions delivered form previously pregnant women to men, increase their risk of dying in the years after the transfusion.
The research was launched by a group of Dutch researchers, who looked at more than 31000 patients who received transfusions and not only the data were sorted by sex, but also by whether the female donors had ever gave birth.
Namely, the results showed that men who received blood from a female donor who had previously been pregnant were 1.5 times more likely to die compared to the cases in which the transfusion was done from a woman who had never been pregnant.
Interesting was that such results were identified only in men under the age of 50, which means the conclusion that men over the age of 50 are immune to whatever specific risk factor is present in the blood of a formerly pregnant female donor.
Over the recent years the issue of blood transfusions between sexes has been quite topical. Henrik Bjursten, another scientist working in the field, published a study which concluded that sex mismatched blood transfusions actually increase mortality risk. Despite the lack of comprehensive evidence Bjursten still thinks we should tend to matching sex when blood transfusing.
"My personal opinion is yes … I would want to have it sex-matched," Bjursten said in a recent interview with Scientific American. "There are millions of lives at risk here. Do we want to take the risk or do we want to go the safe route and try to avoid the harm?"
