IMPORTANCE: Transfusion of red blood cells from female donors has been associated
with increased mortality in male recipients. OBJECTIVE: To quantify the
association between red blood cell transfusion from female donors with and
without a history of pregnancy and mortality of red blood cell recipients.
DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of first-time
transfusion recipients at 6 major Dutch hospitals enrolled from May 30, 2005, to
September 1, 2015; the final follow-up date was September 1, 2015. The primary
analysis was the no-donor-mixture cohort (ie, either all red blood cell
transfusions exclusively from male donors, or all exclusively from female donors
without a history of pregnancy, or all exclusively from female donors with a
history of pregnancy). The association between mortality and exposure to
transfusions from ever-pregnant or never-pregnant female donors was analyzed
using life tables and time-varying Cox proportional hazards models. EXPOSURES:
Red blood cell transfusions from ever-pregnant or never-pregnant female donors,
compared with red blood cell transfusions from male donors. MAIN OUTCOMES AND
MEASURES: All-cause mortality during follow-up. RESULTS: The cohort for the
primary analyses consisted of 31?118 patients (median age, 65 [interquartile
range, 42-77] years; 52% female) who received 59?320 red blood cell transfusions
exclusively from 1 of 3 types of donors (88% male; 6% ever-pregnant female; and
6% never-pregnant female). The number of deaths in this cohort was 3969 (13%
mortality). For male recipients of red blood cell transfusions, all-cause
mortality rates after a red blood cell transfusion from an ever-pregnant female
donor vs male donor were 101 vs 80 deaths per 1000 person-years (time-dependent
"per transfusion" hazard ratio [HR] for death, 1.13 [95% CI, 1.01-1.26]). For
receipt of transfusion from a never-pregnant female donor vs male donor,
mortality rates were 78 vs 80 deaths per 1000 person-years (HR, 0.93 [95% CI,
0.81-1.06]). Among female recipients of red blood cell transfusions, mortality
rates for an ever-pregnant female donor vs male donor were 74 vs 62 per 1000
person-years (HR, 0.99 [95% CI, 0.87 to 1.13]); for a never-pregnant female donor
vs male donor, mortality rates were 74 vs 62 per 1000 person-years (HR, 1.01 [95%
CI, 0.88-1.15]). CONCLUSIONS AND RELEVANCE: Among patients who received red blood
cell transfusions, receipt of a transfusion from an ever-pregnant female donor,
compared with a male donor, was associated with increased all-cause mortality
among male recipients but not among female recipients. Transfusions from
never-pregnant female donors were not associated with increased mortality among
male or female recipients. Further research is needed to replicate these
findings, determine their clinical significance, and identify the underlying
mechanism.
