Hepatoprotective effects of vicenin-2 and scolymoside through the modulation of inflammatory pathways

AbstractThe aim of this study was to investigate the effects of two structurally related flavonoids found inCyclopia subternata, vicenin-2 (VCN) and scolymoside (SCL) on lipopolysaccharide (LPS)-induced liver failure in mice and to elucidate underlying mechanisms. Mice were treated intravenously with VCN or SCL at 12  h after LPS treatment. LPS significantly increased mortality, serum levels of alanine transaminase, aspartate transaminase, and inflammatory cytokines, and toll-like receptor 4 (TLR4) protein expression; these effects of LPS were inhibited by VCN or SCL. It also attenuated the LPS-induced activati on of myeloid differentiation primary response gene 88 and TLR-associated activator of interferon-dependent signaling pathways of the TLR system. Our results suggest that VCN or SCL protects against LPS-induced liver damage by inhibiting the TLR-mediated inflammatory pathway, indicating its potentia l to treat liver diseases.

There is an increasing appreciation of the cardiovascular implications of nonalcoholic fatty liver disease with advanced fibrosis (NAFLD-fibrosis). However, data regarding stroke risk are limited. We sought to investigate whether NAFLD-fibrosis is associated with stroke in addition to heart disease.

Metformin, the first choice drug for type 2 diabetes treatment in all stages of therapy, and one of the most widely prescribed anti-hyperglycemic agent worldwide, represents a rare example of an old drug which continues to display new beneficial effects in various fields. However, lactic acidosis (LA) persists as a serious adverse effect. LA incidence is low and is not necessarily determined by the administration of metformin. Unfortunately, the concern for this complication has negatively affected the drug use, particularly in chronic kidney disease, which may impair drug excretion, and in congestive heart failure and chr...

CONCLUSIONS: In adults with acute HAV infection, SFL may be increased. SFL correlated with the degree of liver injury and hemolysis that occur during the disease. However, in our cohort of HAV patients, who had a relatively benign disease course, SFL were of no prognostic value. PMID: 31599510 [PubMed - in process]

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]

Purpose of review Vitamin D deficiency may impact disease progression of nonalcoholic fatty liver disease (NAFLD). The aim of this work was to review recent studies examining either vitamin D status or the effects of supplementation in patients with NAFLD, along with investigating the roles of genetic polymorphisms and the gut microbiome. Recent findings Six heterogeneous observational studies of vitamin D status, and four randomized controlled intervention trials of vitamin D supplementation in NAFLD were conflicting. All studies were hampered by the challenges of diagnosing NAFLD, were underpowered, and lacked data ...
