Effectiveness and safety of switching to entecavir hepatitis B patients developing kidney dysfunction during tenofovir
2019
Background and Aims: Tenofovir disoproxil fumarate (TDF) is recommended for chronic hepatitis B (CHB) treatment, but it may induce kidney dysfunction whose management is not yet known. This Italian, multicentre, retrospective study aimed to assess the efficacy and safety of switching to entecavir (ETV) patients who developed TDF-associated glomerular and/or tubular dysfunction. Methods: A total of 103 TDF-treated patients were included as follows: age 64 years, 83% male, 49% cirrhotics, 98% with undetectable HBV DNA, 47% with previous lamivudine resistance (LMV-R) and 71% previously treated with adefovir. Twenty-nine (28%) were switched to ETV because estimated glomerular filtration rate (e…
Retinol-Binding Protein 4 Levels Are Associated with Measures of Liver and Renal Function and Oxidant/Antioxidant Status in Obese Children
2013
Serum retinol-binding protein 4 (RBP4) has been proposed as a metabolic risk factor in obesity. We found that RBP4 levels also were associated with liver enzymes and cystatin C. Oxidant stress is a significant feature in obese children with greater values of RBP4 that can mediate the development of comorbidities.
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…
Hepatopulmonary Syndrome in a Patient With Adenocarcinoma of the Colon Metastatic to the Liver and No Apparent Chronic Liver Disease
2006
Hepatopulmonary syndrome consists of a clinical triad: arterial blood deoxygenation, intrapulmonary vasodilation, and liver disease. Both acute and chronic cases of this syndrome have been reported, and the most common cause is cirrhosis. The principle disease mechanism is dilation of the pulmonary blood vessels causing alterations in gas exchange. Increased pulmonary production of nitric acid has been implicated as the primary pathogenic mechanism of vasodilation although it has also been associated with imbalance between vasodilators and vasoconstrictors. We describe the case of a patient with hepatopulmonary syndrome and adenocarcinoma of the colon with metastases to a previously healthy…
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…
Studies on the disposition, metabolism and hepatotoxicity of coumarin in the rat and Syrian hamster.
2002
The hepatotoxicity, metabolism and disposition of coumarin has been compared in male Sprague-Dawley rats and Syrian hamsters. The treatment of rats for 12, 24 and 42 weeks with diets containing 0.2 and 0.5% coumarin resulted in hepatotoxicity and increased relative liver weights. While levels of cytochrome P450 (CYP) and CYP-dependent enzymes were decreased, levels of reduced glutathione (GSH) and activities of UDP glucuronosyltransferase, gamma-glutamyltransferase and GSH S-transferase were increased. In contrast, coumarin produced few hepatic changes in the Syrian hamster. Following a single oral dose of 25 mg/kg [3-14C]coumarin, radioactivity was rapidly excreted by the rat and Syrian ha…
Functional, Biochemical, and Morphological Hepatobiliary Effects in Rats Chronically Exposed to a Steroidal Antiandrogen
1996
Abstract Yellow–brown deposits in intrahepatic bile ducts and portal macrophages were observed for male, but not female, Sprague–Dawley rats fed zanoterone, a steroidal antiandrogen, for ≥3 months. The lesion did not affect biliary canaliculi and was associated with changes of biliary epithelium, portal chronic inflammation, and bile duct proliferation. Deposit formation was assumed to be related to a gender-related anomaly in bile composition and/or flow. Therefore, the pathogenesis of the lesion was investigated in male, female, and orchiectomized rats. Hepatobiliary structure and function were evaluated after 3 months of treatment and 3 months of reversibility. Drug biliary disposition w…
Permanent stenting in “unextractable” common bile duct stones in high risk patients. A prospective randomized study comparing two different stents
2007
BACKGROUND: Endoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND METHODS: We treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relat…
Combined resistance and endurance training at a moderate-to-high intensity improves physical condition and quality of life in liver transplant patien…
2017
Background: Although currently, moderate and high intensity concurrent physical exercise is prescribed in populations with special needs due to its greater effect on physical condition and health-related quality of life (HRQOL), there are no data in the liver transplantation (LT) setting. Aim: To evaluate changes in maximal strength, aerobic capacity, body composition, liver function, and HRQOL in LT patients after a moderate to high intensity combined resistance-endurance training. Material and methods: 6 months after LT, 54 patients were randomized into two groups: intervention group (IG) and control group (CG). 50 patients completed the study with repeat testing at 6 and 12 months after …
Endoscopic treatment of the "sump syndrome" after choledochoduodenostomy: a new technique using an amplatzer septal occluder.
2006
A 58-year-old male patient had been suffering for 35 years from recurrent cholangitis, biliary sludge and infection-induced stone formation after open cholecystectomy because of empyema of the gallbladder and severe acute and delayed postoperative complications. The pathophysiological origin of this chronic "sump syndrome" was a choledochoduodenostomy which had been performed prophylactically at the time of the initial operation. The patient agreed to an experimental treatment option with use of an Amplatzer atrial-septal defect (ASD) occluder for closure of the symptomatic choledochoduodenal fistula. The double-disc occluder was introduced through a 9 French diameter and 90 cm long sheath …
