Factors associated with serum alanine transaminase activity in healthy subjects: Consequences for the definition of normal values, for selection of blood donors, and for patients with chronic hepatitis C
Annie Piton,Thierry Poynard,Françoise Imbert-Bismut,Lina Khalil,Jacques Delattre,Elisabeth Pelissier,Nicole Sansonetti,Pierre Opolon +7 more
TL;DR: Assessment of factors associated with serum ALT activity in apparently healthy subjects and then to apply seven different definitions of ULN in three different populations so as to assess the prevalence of subjects with normal ALT among blood donors and patients before and after treatment.

In situ detection of lipid peroxidation in chronic hepatitis C: correlation with pathological features
Valérie Paradis,Philippe Mathurin,M Kollinger,Françoise Imbert-Bismut,Frédéric Charlotte,Annie Piton,Pierre Opolon,Axel Holstege,Thierry Poynard,Pierre Bedossa +9 more
TL;DR: The presence of MDA adducts in areas of active fibrogenesis and the correlation between the MDA index and fibrosis score suggest a role for lipid peroxidation in liver fibrosis.

Intra-laboratory analytical variability of biochemical markers of fibrosis (Fibrotest) and activity (Actitest) and reference ranges in healthy blood donors
Françoise Imbert-Bismut,Djamila Messous,V Thibaut,Rob B. Myers,Annie Piton,Dominique Thabut,Laure Devers,Bernard Hainque,A. Mercadier,Thierry Poynard +9 more
TL;DR: The low intra-laboratory and intra-patient variability in Fibrotest and Actitest results confirm Fibro test and actitest reliability.

Comparison of Bathophenanthroline Sulfonate and Ferene as Chromogens in Colorimetric Measurement of Low Hepatic Iron Concentration
Laurence Piéroni,Lina Khalil,Frédéric Charlotte,Thierry Poynard,Annie Piton,Bernard Hainque,Françoise Imbert-Bismut +6 more
TL;DR: The aim of the present study was to evaluate the replacement of bathophenanthroline sulfonate with ferene to improve the sensitivity of the colorimetric determination of low HIC.

Intra-individual fasting versus postprandial variation of biochemical markers of liver fibrosis (FibroTest) and activity (ActiTest)
Mona Munteanu,Djamila Messous,Dominique Thabut,Françoise Imbert-Bismut,Mathieu Jouys,J. Massard,Annie Piton,Luminita Bonyhay,Vlad Ratziu,Bernard Hainque,Thierry Poynard +10 more
TL;DR: The intra-individual variation of biochemical markers was low, and it was shown that measurements of FibroTest, ActiTest and their components are not significantly modified by meal intake, which makes the screening of patients at risk of chronic liver diseases more convenient.
