Myeloproliferative diseases (MPDs) represent the commonest cause of splanchnic vein thrombosis (SVT), including Budd-Chiari syndrome (BCS) and portal vein thrombosis (PVT), but their diagnosis is hampered by changes secondary to portal hypertension, while their influence in the outcome of SVT remains unclear. We assessed the diagnostic and prognostic value(More)
Myeloproliferative neoplasms (MPNs) are the most common cause of Budd-Chiari syndrome (BCS) and nonmalignant, noncirrhotic portal vein thrombosis (PVT). In this meta-analysis, we determined the prevalence of MPNs and their subtypes as well as JAK2V617F and its diagnostic role in these uncommon disorders. MEDLINE and EMBASE databases were searched.(More)
BACKGROUND & AIMS The MELDNa score was developed to improve the prognostic value of the MELD score in cirrhosis and was built for serum sodium concentrations numerically capped between 125 and 140 mmol/L. This model is not validated in a well-defined population of patients with cirrhosis and refractory ascites in whom severe hyponatremia (≤ 125 mmol/L) is(More)
BACKGROUND Behcet's disease (BD) is a well-known cause of Budd-Chiari syndrome (BCS). Data are lacking on the presentation and outcome of BCS related to BD. METHODS We investigated the relationship between BD and BCS in 14 patients with both diseases and compared the results to 92 BCS patients without BD. RESULTS Male gender (p = 0.003), North African(More)
contrast and a 'late phase' is probably the most widely used routine to assess the dimensions of SVT. From our point of view, in the subacute setting, SVT is often detected during routine imaging for various symptoms. In this case, Doppler or duplex ultrasound is also capable of making precise assessments of the dimensions of SVT. Question 2: Predisposing(More)
Alcoholic hepatitis (AH) is the most severe form of alcoholic liver disease for which there are no effective therapies. Patients with AH show impaired hepatocyte proliferation, expansion of inefficient ductular cells and high lipopolysaccharide (LPS) levels. It is unknown whether LPS mediates ductular cell expansion. We performed transcriptome studies and(More)
Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction at any level from the small hepatic veins to the atrio-caval junction, in the absence of heart failure or constrictive pericarditis. Various imaging modalities are available for investigating the gross hepatic vascular anatomy but there are rare forms of this disease(More)
Observing animal models of fulminant hepatic failure lead to the hypothesis of a GABAergic origin of the comatose state in hepatic encephalopathy (HE). The hypothesis of hyperstimulation of gamma-aminobutyric acid-benzodiazepine (GABA-BZ) receptors in HE has been tested with a BZ antagonist (flumazenil, Anexate) on 7 patients suffering from severe HE. The(More)
