Abstract
A prospective follow-up study of infants selected by cord blood total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) levels from 2000 consecutive live births was undertaken to reassess the role of cord blood screening in the diagnosis of familial hypercholesterolaemia (FH). Mean values for serum cholesterol were (mmol/l +/- S.D.): TC, 1.83 +/- 0.56; LDL-C, 0.90 +/- 0.49; HDL-C, 0.70 +/- 0.33; TG, 0.38 +/- 0.16. Seventy-three of 117 infants who had had a cord TC and/or LDL-C greater than 95th percentile, and 373 control group children (cord TC and/or LDL-C less than 95th percentile) were followed up at age 3--12 months. Six of the 117 were hypercholesterolaemic (HC), and one child had an HC parent: positive detection rate greater than or equal to 0.05%; false positive rate greater than or equal to 3.7%. Four control-group children were HC and had an HC parent; false negative rate greater than or equal to 1.1%. With the possible exception of detecting FH in a child with a known affected parent, cord blood screening appears to be unreliable for the diagnosis of FH.
