Acoustic radiation force impulse elastography and liver fibrosis risk scores in severe obesity.

Objective: Identifying significant fibrosis is crucial to evaluate the prognosis and therapeutic interventions in patients with nonalcoholic fatty liver disease (NAFLD). We assessed the performance of acoustic radiation force impulse (ARFI) elastography, APRI, FIB-4, Forns, NFS and BARD scores in determining liver fibrosis in severe obesity.

Methods: A prospective study included 108 patients undergoing bariatric surgery.

Association of nonalcoholic fatty liver disease and liver cancer.

Aim: To investigate the association between nonalcoholic fatty liver disease (NAFLD) and liver cancer, and NAFLD prevalence in different liver tumors.

Methods: This is a retrospective study of the clinical, laboratory and histological data of 120 patients diagnosed with primary or secondary hepatic neoplasms and treated at a tertiary center where they underwent hepatic resection and/or liver transplantation, with subsequent evaluation of the explant or liver biopsy. The following criteria were used to exclude patients from the study: a history of alcohol abuse, hepatitis B or C infection, no tumor detected in the liver tissue examined by histological analysis, and the presence of chronic autoimmune hepatitis, hemochromatosis, Wilson's disease, or hepatoblastoma.

Acoustic radiation force impulse elastography and serum fibrosis markers in chronic hepatitis C.

Objective: Liver biopsy (LB) remains the gold standard for the assessment of liver fibrosis, although it is invasive and can have complications. The present study compares several noninvasive methods of fibrosis assessment in chronic hepatitis C (CHC), including acoustic radiation force impulse (ARFI) elastography, aspartate aminotransferase:platelet ratio index (APRI), Forns, FIB-4, and King scores versus percutaneous LB.

Material And Methods: This prospective study enrolled 51 untreated CHC patients.
