Intracerebral Hemorrhage Among Blood Donors and Their Transfusion Recipients

CONCLUSIONS AND RELEVANCE: In an exploratory analysis of patients who received red blood cell transfusions, patients who underwent transfusion with red blood cells from donors who later developed multiple spontaneous ICHs were at significantly increased risk of spontaneous ICH themselves. This may suggest a transfusion-transmissible agent associated with some types of spontaneous ICH, although the findings may be susceptible to selection bias and residual confounding, and further research is needed to investigate if transfusion transmission of cerebral amyloid angiopathy might explain this association.PMID:37698562 | DOI:10.1001/jama.2023.14445
