Hyperferritinemia is a risk factor for steatosis in chronic liver disease.

2009

AIM: To investigate the relationship between ferritin and steatosis in patients with chronically abnormal liver function tests (LFTs) and high ferritin level. METHODS: One hundred and twenty-four consecutive patients with hyperferritinemia (male > 300 ng/mL, female > 200 ng/mL) were evaluated; clinical, biochemical and serological data, iron status parameters, HFE gene mutations and homeostasis model assessment score were obtained. Steatosis was graded by ultrasound as absent or present. Histology was available in 53 patients only. RESULTS: Mean level of ferritin was 881 ± 77 ng/mL in men and 549 ± 82 ng/mL in women. The diagnosis was chronic hepatitis C in 53 (42.7%), non-alcoholic fatty l…

A Sequential Algorithm Combining ADAPT and Liver Stiffness Can Stage Metabolic-Associated Fatty Liver Disease in Hospital-Based and Primary Care Pati…

2020

INTRODUCTION Metabolic-associated fatty liver disease is common, with fibrosis the major determinant of adverse outcomes. Population-based screening tools with high diagnostic accuracy for the staging of fibrosis are lacking. METHODS Three independent cohorts, 2 with both liver biopsy and liver stiffness measurements (LSMs, n = 254 and 65) and a population sample (n = 713), were studied. The performance of a recently developed noninvasive algorithm (ADAPT [age, diabetes, PRO-C3 and platelets panel]) as well as aspartate aminotransferase-to-platelet ratio index, fibrosis-4, nonalcoholic fatty liver disease fibrosis score, and LSM was used to stage patients for significant (≥F2) and advanced …

Cholestasis in newborn infants with perinatal asphyxia

1997

Objective: The aim of this study was to characterize the liver involvement in infants who have both neonatal asphyxia and neonatal cholestasis. Methods: We describe four asphyctic newborn infants (three born at term) who developed early (age 3.8 ± 2.1 days) intrahepatic neonatal cholestasis and in whom tests for causes of neonatal liver damage were negative. Results: The clinical picture and course were benign and similar to that of sporadic 'idiopathic' neonatal hepatitis. Clinical signs and abnormal liver function tests tended to normalize within the first year of life in all. Conjugated bilirubin became normal at 6 months after the onset of cholestasis, while liver enzymes tended towards…

Significance of the effective remnant liver volume in major hepatectomies

2005

The aim of this study is to identify the minimum safe amount of effective remnant liver volume (ERLV) in patients undergoing a major hepatectomy. Thirty-eight consecutive major hepatectomies (resection of ≥3 Couinaud segments) performed between July 1999 and March 2004 in which a frozen section liver biopsy was obtained were included. No patient had chronic viral hepatitis, cirrhosis, or cholestasis. The total liver volume (TLV) was calculated using the Vauthey formula, and the postsurgical liver volume (PSLV) was derived by subtracting the estimated volume of liver resected from the TLV. The PSLV minus the percentage of macrovesicular steatosis as nonfunctional liver was defined as the ef…

Insulin-Like Growth Factor-I, Inflammatory Proteins, and Fibrosis in Subjects With Nonalcoholic Fatty Liver Disease

2013

Inflammation may have a pathogenic role in the progression of nonalcoholic fatty liver disease (NAFLD); by contrast, the role of anti-inflammatory molecules has not been addressed. Low circulating levels of the anti-inflammatory molecule IGF-I have been described in subjects with NAFLD.The aim of the study was to elucidate the clinical significance of IGF-I in NAFLD and its relationship with inflammatory biomarkers and fibrosis.We conducted a cross-sectional study and in vitro experiments on hepatic HepG2 cells at the Internal Medicine and Gastrointestinal and Liver Units of the Universities of Catanzaro and Palermo.A total of 221 individuals with NAFLD diagnosed on ultrasonography (cohort …

Clinical significance of abdominal lymphadenopathy in chronic liver disease

2002

Abstract The possibility of assessing the relationship of ultrasound (US)-detected abdominal lymphadenopathy with etiology, biochemical findings, and histologic data in patients with chronic liver disease was evaluated. US examination of the upper abdomen was performed in 321 consecutive patients with various chronic liver disorders and 56 control patients. The prevalence of lymphadenopathy in chronic liver disease was 38%. This prevalence varied according to etiology of liver disease, from 50% in chronic hepatitis C virus (HCV) to less than 10% in alcoholicc cirrhosis and hepatitis B-virus (HBV)-related chronic liver disease. Patients with lymphadenopathy showed significantly higher serum …

Managing hepatitis C in liver transplant patients with recurrent infection

2009

Tim Zimmermann1, Gerd Otto2, Marcus Schuchmann11Department of Internal Medicine, 2Transplantation Surgery, University of Mainz, GermanyAbstract: Hepatitis C virus (HCV) reinfection after liver transplantation (LT) and recurrent hepatitis C often lead to recurrent cirrhosis (RC). RC is one of the most frequent complications resulting in organ failure and early death after LT in HCV-positive patients with reported 5-year rates from 20% to 40%. As HCV-cirrhosis is one of the leading indications for LT, the therapeutic management is a central issue. To date, the best available therapy is a combination of pegylated interferon + ribavirin in patients with established recurrent hepatitis C proven …

Determining a healthy reference range and factors potentially influencing PRO-C3 – A biomarker of liver fibrosis

2021

Background & Aims Progressive fibrosis has been identified as the major predictor of mortality in patients with non-alcoholic fatty liver disease (NAFLD). Several biomarkers are currently being evaluated for their ability to substitute the liver biopsy as the reference standard. Recent clinical studies in NAFLD/NASH patients support the utility of PRO-C3, a marker of type III collagen formation, as a marker for the degree of fibrosis, disease activity, and effect of treatment. Here we establish the healthy reference range, optimal sample handling conditions for both short- and long-term serum storage, and robustness for the PRO-C3 assay. Methods PRO-C3 was measured in 269 healthy volunteers…

Serum coding and non-coding RNAs as biomarkers of NAFLD and fibrosis severity

2019

Background: In patients with NAFLD liver biopsy is the gold standard to detect NASH and stage liver fibrosis. We aimed to identify differentially expressed mRNAs and non-coding RNAs in serum samples of biopsy-diagnosed mild and severe NAFLD patients with respect to controls and to each other. Methods: We first performed a whole transcriptome analysis through microarray (n=12: 4 CTRL; 4 mild NAFLD: NAS≤4 F0; 4 severe NAFLD NAS≥5 F3), followed by validation of selected transcripts through qPCRs in 88 subjects: 63 NAFLD, 25 CTRL. A similar analysis was also performed on HepG2 exposed to Oleate:Palmitate or only Palmitate (cellular model of NAFL/NASH) at intracellular/extracellular levels. Tran…

Hepatocellular carcinoma and synchronous liver metastases from colorectal cancer in cirrhosis: A case report.

2013

A 68-year-old Caucasian man with hepatitis C virus-related cirrhosis was admitted to our Unit in February 2010 for a diagnostic evaluation of three centimetric hypoechoic focal liver lesions detected by regular surveillance ultrasound. The subsequent computer tomography (CT) led to a diagnosis of unifocal hepatocellular carcinoma (HCC) in VI hepatic segment, defined the other two nodules in the VI and VII segment as suspected metastases, and showed a luminal narrowing with marked segmental circumferential thickening of the hepatic flexure of the colon. Colonoscopy detected an ulcerated, bleeding and stricturing lesion at the hepatic flexure, which was subsequently defined as adenocarcinoma …
