Authors: Carrier P, Debette-Gratien M, Jacques J, Loustaud-Ratti V Abstract The global population is aging, and so the number of older cirrhotic patients is increasing. Older patients are characterised by a risk of frailty and comorbidities, and age is a risk factor for mortality in cirrhotic patients. The incidence of non-alcoholic fatty liver disease as an aetiology of cirrhosis is increasing, while that of chronic viral hepatitis is decreasing. Also, cirrhosis is frequently idiopathic. The management of portal hypertension in older cirrhotic patients is similar to that in younger patients, despite the greater ri...

CONCLUSIONS: Our study showed that the upregulation of NLRP3 inflammasome activated by cardiolipin is crucial in NASH pathogenesis, which might provide a novel potential role of cardiolipin blockade in the treatment of NASH. PMID: 31599445 [PubMed - in process]

Histopathological assessments play an important role in the diagnosis and management of patients with liver disease. For some conditions, liver biopsy is still routinely used to establish the cause of liver disease. In other circumstances, evaluation of morphological changes provides additional information that is useful for clinical management, for example when assessing disease severity in chronic viral hepatitis and non-alcoholic fatty liver disease. However, with the increased use of non-invasive methods for assessing the severity of liver injury, particularly fibrosis, the role of liver biopsy in this respect is changing.

Liver lipid accumulation induced by high-fat diet (HFD) is an early onset process of non-alcoholic fatty liver diseases (NAFLD). Protein kinase A (PKA) is known to be involved in hepatic lipid metabolism. Howe...

Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disorder. NAFLD, associated lipotoxicity, fibrosis, oxidative stress, and altered mitochondrial metabolism, is responsible for systemic inflammation, which contributes to organ dysfunction in extrahepatic tissues, including the heart.We investigated the ability of L-carnitine (LC) to oppose the pathogenic mechanisms underlying NAFLD progression and associated heart dysfunction, in a mouse model of methionine-choline-deficient diet (MCDD).

We report a case of a post RYGB patient with severe malnutrition who developed non-alcoholic fatty liver disease. Severe chronic malnutrition predisposed by bariatric surgery is considered as potential mechanism of hepatic steatosis. Liver function should be routinely monitored for post bariatric patients with nutritional risk. Proper enteral and parenteral nutrition support can be a major treatment for hepatic steatosis induced by severe malnutrition.

Hepatocellular carcinoma (HCC) and cholangiocarcinoma are the two major types of primary liver tumour. Both are increasing in incidence in the UK, in the case of HCC because of the increasing prevalence of chronic liver disease, particularly caused by alcohol and non-alcoholic fatty liver disease. They have a poor overall prognosis because of late presentation and the presence of underlying liver cirrhosis in patients with HCC. Patients usually present with a liver mass or jaundice. Assessment is primarily radiological by means of computed tomography and/or magnetic resonance imaging.
