Intravenous high-dose furosemide and hypertonic saline solutions for refractory heart failure and ascites.
2011
Several studies have shown the efficacy of hypertonic saline solution infusion in conditions in which regional organ blood flow is impaired. Our group has shown that treatment of patients with diuretic-resistant heart failure with high-dose furosemide plus hypertonic saline is effective and well tolerated, improving symptoms of congestion, reducing plasma levels of markers of neurohormonal and inflammatory activation, decreasing hospital readmission rates, and reducing long-term mortality. The same regimen was shown to be better than repeated paracentesis in patients with cirrhosis and refractory ascites, yielding better control of ascites, pleural effusions, and/or leg edema without an inc…
Transjugular intrahepatic portosystemic shunt (TIPS) complications: what diagnostic radiologists should know
2022
Transjugular intrahepatic portosystemic shunt (TIPS) is an effective therapy for portal hypertension complications and can successfully treat variceal bleeding and refractory ascites. Although TIPS is relatively safe, procedural- or shunt-related morbidity can reach 20%, and procedural complications have a fatality rate of 2%. Delayed recognition and treatment of TIPS complications can lead to life-threatening clinical scenarios. Complications can vary from stent migration or malpositioning to nontarget organ injury, TIPS dysfunction, encephalopathy, or liver failure. This review aims to outline the role of diagnostic radiology in assessing post-TIPS complications.[GRAPHICS].
Cirrhotic patients with minimal hepatic encephalopathy have increased capacity to eliminate superoxide and peroxynitrite in lymphocytes, associated w…
2018
Patients with minimal hepatic encephalopathy (MHE) show increased oxidative stress in blood. We aimed to assess whether MHE patients show alterations in different types of blood cells in (a) basal reactive oxygen and nitrogen species levels; (b) capacity to metabolise these species. To assess the mechanisms involved in the altered capacity to metabolise these species we also analysed: (c) peroxynitrite formation and d) peroxynitrite reaction with biological molecules. Levels of reactive oxygen and nitrogen species were measured by flow cytometry in blood cell populations from cirrhotic patients with and without MHE and controls, under basal conditions and after adding generators of superoxi…
Non invasive blood flow measurement in cerebellum detects minimal hepatic encephalopathy earlier than psychometric tests
2013
AIM: To assess whether non invasive blood flow measurement by arterial spin labeling in several brain regions detects minimal hepatic encephalopathy. METHODS: Blood flow (BF) was analyzed by arterial spin labeling (ASL) in different brain areas of 14 controls, 24 cirrhotic patients without and 16 cirrhotic patients with minimal hepatic encephalopathy (MHE). Images were collected using a 3 Tesla MR scanner (Achieva 3T-TX, Philips, Netherlands). Pulsed ASL was performed. Patients showing MHE were detected using the battery Psychometric Hepatic Encephalopathy Score (PHES) consisting of five tests. Different cognitive and motor functions were also assessed: alterations in selective attention we…
Altered postural control and stability in cirrhotic patients with minimal hepatic encephalopathy correlate with cognitive deficits
2017
Background & Aims: Cognitive dysfunction in cirrhotic patients with minimal hepatic encephalopathy (MHE) is associated with falls. Alterations in postural control and stability could contribute to increase falls risk in these patients. We aimed to assess whether postural control and direction-specific limits of stability are altered in cirrhotic patients with MHE compared to patients without MHE and controls. We also assessed if alterations in postural control correlate with neurological impairment and/or blood biomarkers. Methods: Posturography analysis, attention Stroop test and bimanual and visuo-motor coordination tests were performed in 18 controls, 19 patients with cirrhosis without M…
The PHES battery does not detect all cirrhotic patients with early neurological deficits, which are different in different patients.
2017
Background and aims The psychometric hepatic encephalopathy score (PHES) is the “gold standard” for minimal hepatic encephalopathy (MHE) diagnosis. Some reports suggest that some cirrhotic patients “without” MHE according to PHES show neurological deficits and other reports that neurological alterations are not homogeneous in all cirrhotic patients. This work aimed to assess whether: 1) a relevant proportion of cirrhotic patients show neurological deficits not detected by PHES; 2) cirrhotic patients with mild neurological deficits are a homogeneous population or may be classified in sub-groups according to specific deficits. Methods Cirrhotic patients “without” (n = 56) or “with” MHE (n = 4…
Validation of the simplified Animal Naming Test as primary screening tool for the diagnosis of covert hepatic encephalopathy
2019
Diagnosis of covert hepatic encephalopathy (CHE) is time consuming in clinical practice. Recently, a new diagnostic tool - the simplified Animal Naming Test (S-ANT1) - was presented with promising results in an Italian cohort. The aim of the present study was to validate S-ANT1 in a cohort of cirrhotic patients from a German tertiary referral centre.143 cirrhotic patients and 37 healthy controls were enrolled. Hepatic encephalopathy (HE) grade 1 (HE1) was clinically diagnosed according to the West-Haven Criteria. Critical flicker frequency and Psychometric Hepatic Encephalopathy Score were used to detect minimal HE (MHE). All participants were additionally examined by S-ANT1.58 (40.6%) pati…
Value of the critical flicker frequency in patients with minimal hepatic encephalopathy
2007
Minimal hepatic encephalopathy (MHE) is mainly diagnosed using psychometric tests such as the psychometric hepatic encephalopathy score (PHES). Despite the clinical and social relevance of MHE, psychometric testing is not widespread in routine clinical care. We assessed the usefulness of the critical flicker frequency (CFF), for the diagnosis of MHE and for the prediction of the development of overt episodes of HE. The normal range of PHES in the Spanish population was evaluated in a control group. Subsequently, 114 patients with cirrhosis and 103 healthy controls underwent both PHES and CFF tests. A diagnosis of MHE was made when the PHES was lower than −4 points. Patients were followed-up…
High efficacy of direct-acting anti-viral agents in hepatitis C virus-infected cirrhotic patients with successfully treated hepatocellular carcinoma
2018
Background: The efficacy of direct-acting anti-viral (DAA) therapy in patients with a history of hepatocellular carcinoma (HCC) is unknown. Aim: We prospectively evaluated whether previously treated HCC affects DAA efficacy in a large real-life cohort of cirrhotic patients. Methods: From January to December 2015 all consecutive HCV mono-infected patients with cirrhosis and/or history of HCC attending 10 Italian tertiary liver centres were enrolled. Baseline characteristics and response to therapy were recorded. 1927 patients were enrolled (mean age: 62.1 10.9 years; 1.205 males). Genotype 1 was the most frequent (67.9%) followed by genotypes 3 (12.4%), 2 (11.2%) and 4 (8.6%). 88.4% and 10.9…
Acute and reversible Pisa syndrome as unusual presentation of portosystemic encephalopathy
2020
Abstract We present the first case of acute and reversible Pisa Syndrome, as a clinical manifestation of a portosystemic encephalopathy bout occurring in a patient affected with cirrhosis and clinical-radiological signs of acquired hepatocerebral degeneration, without exposure to psychotropic medications. A 62 year-old man suffering from cirrhosis was admitted to our hospital for sudden onset of mild confusion and postural change. He was observed walking and standing with a tilt toward the right during the last two hours. On neurological examination, he showed bilateral asterixis and extrapyramidal signs. Clinical diagnosis of Pisa Syndrome was made in a setting of raised serum ammonia. A b…
