Somatic mutations activating telomerase reverse-trancriptase promoter were recently identified in several tumour types. Here we identify frequent similar mutations in human hepatocellular carcinomas (59%), cirrhotic preneoplastic macronodules (25%) and hepatocellular adenomas with malignant transformation in hepatocellular carcinomas (44%). In(More)
Hepatocellular adenomas (HCA) are benign liver tumors predominantly developed in women using oral contraceptives. Here, exome sequencing identified recurrent somatic FRK mutations that induce constitutive kinase activity, STAT3 activation, and cell proliferation sensitive to Src inhibitors. We also found uncommon recurrent mutations activating JAK1, gp130,(More)
Meningiomas are common central nervous system tumors. The World Health Organization (WHO) defines three grades, predictive of the risk of recurrence. These tumors can relapse frequently and sometimes undergo malignant transformation. Maintenance of telomere length is a key process in malignant progression, and mutations in TERT promoter have recently been(More)
BACKGROUND Hepatitis C virus (HCV) is the aetiological agent for most cases of cryoglobulinaemia vasculitis. Interferon-containing regimens are associated with important side effects and may exacerbate the vasculitis. OBJECTIVE To evaluate safety and efficacy of an oral interferon-free regimen, sofosbuvir plus ribavirin, in HCV-cryoglobulinaemia(More)
Hepatocellular carcinomas (HCCs) are liver tumors related to various etiologies, including alcohol intake and infection with hepatitis B (HBV) or C (HCV) virus. Additional risk factors remain to be identified, particularly in patients who develop HCC without cirrhosis. We found clonal integration of adeno-associated virus type 2 (AAV2) in 11 of 193 HCCs.(More)
BACKGROUND Hepatic encephalopathy (HE) is a frequent complication of cirrhosis and a major public health problem. The incidence is increasing because of improved cirrhosis prognosis. The most widely used scale used to evaluate HE is the West-Haven (WH) scale, with scores ranging from 0 to 4. This scale is easy to use but not suitable for patients with(More)
BACKGROUND One study has suggested that markers of acute hepatitis E virus (HEV) infection are present in 3.6% of patients with severe alcoholic hepatitis (AH). However, validation of these preliminary results is lacking, as well as the impact of HEV infection on the 6-month survival. AIMS The aims of this study were to evaluate the prevalence of HEV(More)
