Single-donor platelets are stored up to 5 days prior to transfusion. Since contact of plasma to plastic surfaces may lead to complement activation, we investigated whether there is any increase in the complement factors C3a, C4a and C5a in routinely stored single-donor platelet concentrates. C3a levels increased about 40-fold during a 7-day storage. C4a levels also increased with storage time but to a lesser extent. By contrast, C5a levels remained stable throughout this period. ADP- and collagen-induced aggregation was impaired after storage of platelets, indicating severe functional injury. In platelet-poor plasma stored under identical conditions a comparable increase in C3a and C4a concentrations was observed. The loss of platelet function during storage might at least in part be due to the excessive anaphylatoxin concentrations observed.
