Pregnancy outcome of women transfused during pregnancy with blood products inadvertently obtained from donors treated with acitretin

Abstract

We assessed the pregnancy outcome of nine women inadvertently transfused with acitretin-contaminated blood products in South Korea. A total of 18 women matched to cases by age, gravidity, and singleton- or twin-pregnancy, and who were transfused with blood products not contaminated with acitretin, was also recruited. There were nine babies born in the case group. No differences (p > 0.05) were observed between cases and controls in the gestational age at delivery (38.3 +/- 1.6 weeks vs 37.8 +/- 2.2 weeks), birth weight (3,146 +/- 874 g vs 3,106 +/- 568 g), rate of pre-term deliveries (22.2% vs 11.1%) and rate of low birth weight (<2,500 g) (33.3% vs 16.7%). There was no case of malformation or neurological abnormalities born in either group. In conclusion, inadvertent exposure to acitretin-contaminated blood products was not associated with adverse pregnancy outcomes, probably because of the removal of acitretin and etretinate during the manufacturing process of blood products.
