military personnel who receive line of descent transfusions from women who have been pregnant are more potential to die , a study has found . Scientists from Sanquin Research found that transfusions from blood giver who have been fraught were link with an increased peril of mortality rate in manlike recipients , but not distaff recipient role .
The study look at 31,118 patients who had received 59,320 crimson ancestry cell transfusions between 2005 and 2015 in major hospitals in the Netherlands . By compare survival rate of the receiver , they found " a statistically meaning addition in all - suit deathrate among male recipients of red parentage cell transfusions " .
In total , 3,969 patient role studied choke after their transfusion , with the lead cause being transfusion - related keen lung injury .
The researchers found that man under the age of 50 were 1.5 time more likely to die within three year , if they incur a transfusion from a womanhood who had been pregnant before donating .
Whilst substantial , this is n’t a huge increase , but nevertheless , it could have implications for transfusion in the future tense if the same result are replicated elsewhere . The same results were not come across in distaff recipient of descent transfusion , and their deathrate was not affected in any statistically pregnant way . Their results are published in theJournal of the American Medical Association .
The researcher suggested that this growth in risk of exposure of mortality could be due to antibodies acquired during maternity .
“ The connexion of increase mortality among male patients who received transfusion from ever - fraught donors indicate a possible mechanism found on immunologic change occur during maternity , " Dr Rutger Middelburg from Sanquin Research say , reportsthe Telegraph .
“ An alternative explanation could be a deviation in iron position between ever - pregnant female and male donors . Some bailiwick also cover differences in red blood prison cell physiology between the sexes . "
The author point out that further research is needed " to replicate these determination , determine their clinical significance , and identify the underlying chemical mechanism . ”
" These results are provocative and may – if true – have pregnant clinical entailment , " Ritchard G Cable MD compose in aneditorial on the JAMA internet . However , he urged carefulness , and stated that other clinical trials have had different result .
The National Health Service in the UK secern the Telegraph that blood donations from all donor were welcome and that they continue to welcome donations from women who have been pregnant .
