Journal ArticleDOI
Sampling variability of liver biopsy in nonalcoholic fatty liver disease.
Vlad Ratziu,Frédéric Charlotte,A. Heurtier,Sophie Gombert,Philippe Giral,Eric Bruckert,André Grimaldi,Frédérique Capron,Thierry Poynard +8 more
TL;DR: Histologic lesions of NASH are unevenly distributed throughout the liver parenchyma; therefore, sampling error of liver biopsy can result in substantial misdiagnosis and staging inaccuracies.
Journal ArticleDOI
Biochemical markers of liver fibrosis in patients with hepatitis C virus infection : a prospective study
Françoise Imbert-Bismut,Vlad Ratziu,Laurence Piéroni,Frédéric Charlotte,Yves Benhamou,Thierry Poynard +5 more
TL;DR: A combination of basic serum markers could be used to substantially reduce the number of liver biopsies done in patients with chronic HCV infection.
Journal ArticleDOI
Liver fibrosis progression in human immunodeficiency virus and hepatitis C virus coinfected patients
Yves Benhamou,Marie Bochet,V. Di Martino,Frédéric Charlotte,F. Azria,Anne Coutellier,Michel Vidaud,François Bricaire,Pierre Opolon,Christine Katlama,Thierry Poynard +10 more
TL;DR: In coinfected patients, a low CD4 count, alcohol consumption rate, and age at HCV infection are associated with a higher liver fibrosis progression rate, while HIV seropositivity accelerates HCV‐related liver Fibrosis progression.
Journal ArticleDOI
Liver fibrosis in overweight patients.
Vlad Ratziu,Philippe Giral,Frédéric Charlotte,Eric Bruckert,Vincent Thibault,Ioannis Theodorou,Lina Khalil,Gérard Turpin,Pierre Opolon,Thierry Poynard +9 more
TL;DR: A clinicobiological score combining age, BMI, triglycerides, and ALT had 100% negative predictive value for septal fibrosis when scoring 0 or 1 (100% sensitivity for a specificity of 47%).
Journal ArticleDOI
