A 24-year-old man was admitted due to acute hepatitis with unknown etiology. After his condition and laboratory data gradually improved with conservative therapy, he was discharged 1 month later. Two months after his discharge, however, liver dysfunction reappeared. After his mother accidentally revealed that he took complementary and alternative medicine, discontinuation of the therapy caused his condition to improve. Finally, he was diagnosed with a recurrent drug-induced liver injury associated with Japanese complementary and alternative medicine...

Liver and kidney diseases are a global concern, therefore considerable efforts to obtain fine herbs useful as drugs from medicinal plants are currently in progress. The aim of this work was to study the antioxidant effects of previous supplementation with fenugreek seeds (FS) against carbon tetrachloride (CCl4) toxicity in the liver and kidney. CCl4 toxicity was induced by one dose (i.g. 5ml CCl4/kg of body weight, 50% CCl4 in olive oil) after 7 weeks of normal diet or diet rich in 10% of grinded fenugreek seeds (20g of pellet rat food/rat/day)...

Pirfenidone (PFD), an anti-fibrotic small molecule drug, is used to treat fibrotic diseases, but its effects on myocardial infarction (MI)-induced cardiac fibrosis are unknown. The aim of this study was to determine the effects of PFD on MI-induced cardiac fibrosis and the possible underlying mechanisms in rats. After establishment of the model, animals were administered PFD by gavage for 4 weeks. During the development of MI-induced cardiac fibrosis, we found activation of a positive feedback loop between the angiotensin II type 1 receptor (AT1R)/phospho-p38 mitogen-activated protein kinase (p38 MAPK) pathway and renin-angiotensin system (RAS), which was accompanied by down-regulation of liver X receptor-α (LXR-α) expression...

BACKGROUND: Drug is an important cause of liver injury and accounts for up to 40% of instances of fulminant hepatic failure. Drug-induced liver injury (DILI) is increasing while the diagnosis becomes more difficult. Though many drugs may cause DILI, Chinese herbal medicines have recently emerged as a major cause due to their extensive use in China. We aimed to provide drug safety information to patients and health carers by analyzing the clinical and pathological characteristics of the DILI and the associated drug types...

Antitubercular therapy (ATT)-induced hepatotoxicity is often over looked and active tuberculosis is considered a contraindication for liver transplantation, however it might be the only lifesaving option to certain patients of acute liver failure (ALF) due to ATT. We have assessed the outcome of live donor liver transplantation in ATT-induced ALF. A retrospective analysis of all the cases of ALF that underwent liver transplantation from 2006 to 2014 at the Amrita Institute of Medical Sciences was done. A total of seven (7...

Acute liver injury and acute liver failure are syndromes characterized by a rapid loss of functional hepatocytes in a patient with no evidence of pre-existing liver disease. A variety of inciting causes have been identified, including toxic, infectious, neoplastic, and drug-induced causes. This article reviews the pathophysiology and clinical approach to the acute liver injury/acute liver failure patient, with a particular emphasis on the diagnostic evaluation and care in the acute setting.

Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care...

Diabetes (one of non-communicable diseases) is serious due to its complications, such like, cardiovascular ailments, neuropathy, nephropathy, retinopathy, wound gangrene and sexual impotence. Diabetes and associated chronic conditions are rapidly emerging as major health problems. In clinical, there were different drugs for diabetes treatment on different mechanisms. However, there were limited studies on the efficacy of electric stimulations on diabetes therapeutic application. In current study, we try to evaluate the effect of microcurrent electrical nerve stimulator (MENS) on diabetes modulation as an alternative medicine...

PURPOSE: MicroRNAs (miRNA or miR) are the most abundant and stable class of small RNA. Unlike the typical RNA molecules present in the cell, they do not encode proteins but can control translation. and Hhence, they are found to play a major role in the regulation of cellular processes. miRNAs have been shown to differentially regulate various genes, and the expression levels of some miRNAs changes several fold in liver and serum, during drug- induced toxicity. This review summarises some of the latest findings about the biological functions of miRNA and its potential use as diagnostic biomarkers in drug- induced liver injury...

Hepatocellular carcinoma (HCC) represents approximately 85% of all primary liver cancer cases. Non-alcoholic fatty liver disease (NAFLD) is one of the risk factors for HCC. NAFLD occurs in patients with components of metabolic syndrome, such as type 2 diabetes mellitus, obesity, hypertension and hyperlipidemia. Therefore, hyperlipidemia also represents a patient population at risk for HCC that can readily be identified. Rosuvastatin, a 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitor, has exhibited a more potent affinity for the active site of HMG-CoA reductase than other statins...

BACKGROUND & AIMS: The paradox of selective hepatic insulin resistance, wherein the insulin-resistant liver fails to suppress glucose production but continues to produce lipids, has been central to the pathophysiology of hepatosteatosis and hyperglycemia. Our study was designed to investigate the mechanism(s) by which microRNA-206 alleviates the pathogenesis of hepatosteatosis and hyperglycemia. METHODS: Dietary obese mice induced by a high fat diet were used to study the role of microRNA-206 in the pathogenesis of hepatosteatosis and hyperglycemia...

Liver fibrosis represents a frequent event following chronic insult to trigger wound healing reactions with abnormalities of angiogenesis in the liver. Capillarization of liver sinusoidal endothelial cell (LSEC) is the pivotal event during liver angiogenesis. In the current study, we sought to investigate the effect of tetramethylpyrazine (TMP) on carbon tetrachloride (CCl4)-induced liver injury and fibrosis in rats, and to further examine the molecular mechanisms of TMP-induced anti-angiogenic effect. We found that TMP significantly ameliorated histopathological feature of liver fibrosis characterized by decreased collagen deposition, hepatocyte apoptosis, and expression of biochemical indicators, such as aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP)...

Sodium-glucose cotransporter 2 inhibitors are a new class of oral hypoglycemic agents, and thus safety data are limited. We present a 48-year-old woman with type 2 diabetes mellitus and Child's Class A cirrhosis secondary to nonalcoholic steatohepatitis presenting with jaundice and acute cholestatic liver injury. Other than starting dapagliflozin, she reported no medication changes or supplement use. Before treatment, her total bilirubin was 1.2 mg/dL. On admission, her liver values were elevated and liver biopsy was consistent with drug-induced liver injury...

This mini-review highlights our and others' experience about in vitro and in vivo models that are being used to follow up events of liver injuries under various hepatotoxic agents and potential hepatoprotective drugs. Due to limitations of the outcomes in each model, we focus primarily on two models. First, a developed perfusion method for isolated immobilized hepatocytes that improves the process of oxygenation and helps in end-product removal is of considerable value in improving cell maintenance. This cellular model is presented as a short-term research-scale laboratory bioreactor with various physiological, biochemical, molecular, toxicological and pharmacological applications...

OBJECTIVE: Idiosyncratic drug-induced liver injury (DILI) is a multifactorial complex disease, in which the toxic potential of the drug, together with genetic and acquired factors and deficiencies in adaptive processes which limit the extent of damage, can determine susceptibility and make individuals unique in their development of hepatotoxicity. The aim of this study is to analyse the genetic factors (HLA, cytokine polymorphisms and KIR genotype) of children who experience an episode of drug-induced liver injury...

The identification of the key regulators of bile acid synthesis and transport within the enterohepatic circulation has unravelled potential targets for pharmacological therapies of cholestatic liver diseases. Novel drug targets include the bile acid receptors FXR and TGR5, the bile acid-induced gut hormones FGF19 and GLP-1, and the bile acid transport systems ASBT and NTCP within the enterohepatic circulation. Moreover, bile acid derivatives undergoing cholehepatic shunting may allow improved targeting to the bile ducts...

Glucose is a major energy source for the entire body, while fructose metabolism occurs mainly in the liver. Fructose consumption has increased over the last decade globally and is suspected to contribute to the increased incidence of non-alcoholic fatty liver disease (NAFLD). NAFLD is a manifestation of metabolic syndrome affecting about one-third of the population worldwide and has progressive pathological potential for liver cirrhosis and cancer through non-alcoholic steatohepatitis (NASH). Here we have reviewed the possible contribution of fructose to the pathophysiology of NAFLD...

Accumulating evidence identifies autophagy as an inflammation-related defensive mechanism against diseases including liver fibrosis. Therefore, autophagy may represent a new pharmacologic target for drug development to treat liver fibrosis. In this study, we sought to investigate the effect of dihydroartemisinin (DHA) on autophagy, and to further examine the molecular mechanisms of DHA-induced anti-inflammatory effects. We found that DHA appeared to play an essential role in controlling excessive inflammation...

: Epithelial-to-mesenchymal transition (EMT) is linked to tumor invasion, drug resistance and aggressive disease and this is largely dependent on the cell's microenvironment. Acriflavine (ACF) is an old antibacterial drug recently also suggested as anticancer agent and HIF inhibitor. We wanted to study the effect of acriflavine on EMT in different human cancer models. Pancreatic cancer cells (Panc-1) were exposed to TGF-β1 or cobalt chloride (to mimick severe hypoxia) to induce EMT. For our third model we exposed HepG2 liver cancer cells to sorafenib which resulted in development of acquired drug resistance with strong features of EMT and aggressive behavior...
