Blood Transfusion From Women To Men - Risk Affair
We as the common people are not aware of a lot of facts and findings related to health due to a lot many reasons. One of them could be probably this new study that states that blood transfusion from women to men could be a risky decision. Around 13% of the subjects that were studies for blood transfusion from females who had been pregnant before were more likely to die during the period of study compared to subjects who received blood from male donors. Also, those subjects who received blood from female donors who had not been pregnant before were not at an increased risk as compared to those who received from other men. Furthermore women who received blood from female donors who have been or haven't been pregnant before are not at increased risk compared to women who received blood from male donors.
Though these results are preliminary in nature the researchers do feel that further more results could result into more findings that are proven and could affect the blood donation and transfusion process as well. As on day, it is not clear why the blood of previously pregnant women increases the risk of death in males but researchers do feel that the changes that occur in the immune system of a female undergoing pregnancy could play a role in the same.
A recent study where over 30,000 subjects were studied to receive RBC transfusions from three different donors divided as male female and females with a history of pregnancy. The study was carried out across the year post transfusions. During the study period around 4000 subjects died. The ratio for males was 101 deaths per 1000 amongst those who received blood from previously pregnant women and 80 deaths per 1000 for subjects who received blood from male donors. Death rate was more in the age group of 50 or younger. In women subjects receiving blood from either of the female donors, pregnant before or not, there was no increase in risk of death.
Doctors are generally aware that in rare blood transfusion cases the receiver could develop a transfusion related acute lung injury condition (TRALI) and could result into death, but antibodies that women develop during pregnancy could trigger TRALI in male recipients is a possibility they presume to an extent because the study had its own limitations as well. Hence, this research is of significant importance because the studies might lead the blood banks to consider donation risks and further modify the donation system to prevent issues like this.
