Adverse Occurrence type:
Guastafierro: Case Report
Time to detection:
Alerting signals, symptoms, evidence of occurrence:
Following removal of the sigmoid colon, the patient received 3 units of red cells. Six days later, the hemoglobin level decreased and biochemical serum values showed Hb 6.2 g/dL, LDH 975 I.U./L and total bilirubin 2.95 mg/dL (direct 0.35 mg/dL).
Demonstration of imputability or root cause:
Crossmatches with red cell suspension of transfused blood units and a post-transfusion serum were repeatedly positive. Laboratory tests showed the presence of anti-S alloantobody in the serum and eluate. Moreover, pre-transfusion serum of the patient was retrospectively retested: anti-S was not detected.

Expert comments for publication:
The antibodies of the MNS system to glycophorin B, anti-S, -s, and -U can all cause immediate and delayed hemolytic transfusion reactions, and anti-U is a particularly dangerous antibody.
