Adverse Occurrence type:
MPHO Type:
Estimated frequency:
In general, the incidence of passively mediated hemolytic transfusion reactions associated with platelet transfusions are: 1:1000-1:25,000 for all platelet transfusions and 1:100-1:9000 for minor-mismatched platelet transfusions. The incidence of higher titer anti-B antibody formation after taking probiotics was not determined.
Time to detection:
15 minutes
Alerting signals, symptoms, evidence of occurrence:
Severe back and flank pain associated with hypertension and chest pain. A posttransfusion specimen was noted to be grossly hemolyzed and the urine specimen was dark brown. Hemoglobin decreased 2-4 g/dL. Bilirubin increased and peaked at 7-9 hours post-transfusion.
Demonstration of imputability or root cause:
Serologic evaluatoin and blocking antibody titers with suspension of probiotic pills and evaluation of previous transfusion recipients' clinical course.
Imputability grade:
3 Definite/Certain/Proven
