title: [Cholesterol concentrations in cord blood of newborn infants].
abstract: OBJECTIVE
  Familial hypercholesterolemia (FH) is an autosomal dominant disease with an estimated worldwide prevalence of 0.2%. It is caused by a multitude of low density lipoprotein receptor gene mutations. It is characterized with high levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and a high incidence of coronary artery disease in young adults. Cord blood cholesterol concentration is used for mass screening of FH. The purpose of this study was to detect the lipid levels of cord blood in newborn infants from China and to determine the cut-off point after 1 to 2 years follow-up.
  
  
  METHODS
  TC, triglycerides (TG), LDL-C and high density lipoprotein cholesterol (HDL-C) were determined in 242 healthy full-term newborn infants.
  
  
  RESULTS
  The mean values of TC, TG, LDL-C and HDL-C in cord blood were (1.69 +/- 0.40) mmol/L, (0.23 +/- 0.12) mmol/L, (0.81 +/- 0.21) mmol/L and (0.58 +/- 0.16) mmol/L (mean +/- standard deviation), respectively. The HDL-C concentration in male neonates was lower than that in female neonates (P < 0.05).
  
  
  CONCLUSIONS
  After the follow-up of 1 to 2 years for FH, the recommended screening cut-off points were TC > or = 2.47 mmol/L and LDL-C > or = 0.89 mmol/L.
