Acute haemolytic transfusion reaction after transfusion of fresh frozen plasma in a neonate-Preventable by using...

Plasma is a commonly used blood product and is available in the form of fresh frozen plasma (FFP) or pooled solvent/detergent-treated plasma. In the Netherlands, solvent/detergent-treated plasma has become the standard product in the adult population since several years, but for neonatal use, FFP remains the product of preference.

A preterm neonate developed lung bleeding at day 8 postpartum, for which intubation and mechanical ventilation was required and transfusions with packed red blood cells and plasma, in the form of FFP, were given. Five hours after transfusion, a red discoloration of the urine occurred. An acute haemolytic transfusion was suspected, confirmed by laboratory investigations (fast decrease in haemoglobin, increased free haemoglobin, decreased haptoglobin, increased lactate dehydrogenase and a positive direct antiglobulin test [IgG 2+]). Additional research showed that the FFP product contained nonspecific auto-antibodies that reacted with the transfused erythrocytes, most test erythrocytes and the donor's own erythrocytes.

A neonate experienced an acute haemolytic reaction, most probably caused by administrating a FFP product containing auto-antibodies. If transfused with solvent/detergent-treated plasma, such antibodies would have been diluted or captured. This case adds a new argument to the discussion on expanding the use of solvent/detergent-treated plasma to the paediatric population.
