  1. Screening of newborn infants for cholestatic hepatobiliary disease with tandem mass spectrometry. Commentary.

    Article - En anglais

    Objective To assess the feasibility of screening for cholestatic hepatobiliary disease and extrahepatic biliary atresia by using tandem mass spectrometry to measure conjugated bile acids in dried blood spots obtained from newborn infants at 7-10 days of age for the Guthrie test Setting Three tertiary referral clinics and regional neonatal screening laboratories.

    Design Unused blood spots from the Guthrie test were retrieved for infants presenting with cholestatic hepatobiliary disease and from the two cards stored on either side of each card from an index child.

    Concentrations of conjugated bile acids measured by tandem mass spectrometry in the two groups were compared.

    Main outcome measures Concentrations of glycodihydroxycholanoates, glycotrihydroxycholanoates, taurodihydroxycholanoates, and taurotrihydroxycholanoates.

    Receiver operator curves were plotted to determine which parameter (or combination of parameters) would best predict the cases of cholestatic hepatobiliary disease and extrahepatic biliary atresia.

    The sensitivity and specificity at a selection of cut off values for each bile acid species and for total bile acid concentrations for the detection of the two conditions were calculated.

    Results 218 children with cholestatic hepatobiliary disease were eligible for inclusion in the study.

    Two children without a final diagnosis and five who presented at<14 days of age were excluded. (...)
