Although not associated with the metabolic syndrome, HCV is linked with impaired insulin signalling, insulin resistance, hypocholesterolemia and steatosis which represent a distinct HCV-associated dysmetabolic syndrome. Insulin resistance affects the development of diabetes, fibrosis, impaired response to antivirals and perhaps hepatocellular carcinoma risk. HCV infection is associated with hypocholesterolemia and steatosis reversible after sustained virologic response. A "viral", and a "metabolic" steatosis exist as function of viral genotypes. Little is known about the possible role of HCV in further components of the metabolic syndrome such as atherosclerosis, obesity, arterial hypertension, hyperuricemia and thrombotic risk factors.

Nonalcoholic fatty liver disease (NAFLD) is considered to be a hepatic manifestation of metabolic syndrome. The clinicopathologic spectrum ranges from simple steatosis to nonalcoholic steatohepatitis (NASH). Simple steatosis has a relatively benign clinical course, but NASH can progress to cirrhosis and hepatocellular carcinoma. As yet there is no convincingly effective treatment for NAFLD and the best option for these patients might be a multimodal treatment plan targeting obesity, insulin resistance, diabetes mellitus, hyperlipidemia and hypertension.

Blumea balsamifera (also known as sambong), a medicinal plant, is known to improve physiological disorders such as rheumatism and hypertension. However, its anticancer activity has not been well elucidated. In this study, we found that Blumea balsamifera MeOH extract (BME) induced growth inhibitory activity in rat and human hepatocellular carcinoma cells (McA-RH7777, HepG2, respectively) without cytotoxicity as in with rat hepatocytes used as a normal cell model. BME induced cell cycle arrest at G1 phase via decreases in expression of cyclin-E and phosphorylation of retinoblastoma (Rb) protein in both dose- and time-dependent manners. Furthermore, BME reduced the level of a proliferation related ligand (APRIL) which stimulates tumor cell growth. The anti-proliferative effect of BME was improved slightly but significantly by the treatment with recombinant human APRIL. These findings suggest that BME may have a possible therapeutic potential in hepatoma cancer patients and the depletion of cellular APRIL may be one of the important mechanisms on the growth inhibitory effect of BME.

Blumea balsamifera is known to improve physiological disorders such as rheumatism and hypertension, but its anticancer activity has not been well elucidated. In this study, we found that Blumea balsamifera MeOH extract (BME) induced growth-inhibitory activity in rat and human hepatocellular carcinoma cells without cytotoxicity in rat hepatocytes which were used as a normal cell model. BME induced cell cycle arrest at the G1 phase via decreases in the expression of cyclin-E and phosphorylation of retinoblastoma protein. Furthermore, BME reduced the level of a proliferation-inducing ligand, that stimulates tumor cell growth. These findings suggest that BME has possible therapeutic potential in hepatoma cancer patients and that depletion of cellular APRIL is an important mechanism in the growth-inhibitory effect of BME.

Non-alcoholic fatty liver disease is present in 15-25% of the general population. The fundamental derangement in non-alcoholic fatty liver disease is insulin resistance, a key component of the metabolic syndrome, which includes type 2 diabetes mellitus, dyslipidemia, hypertension, and obesity. The natural history of non-alcoholic fatty liver disease is not always benign, and causality for chronic liver disease and cirrhosis is well known in clinical practice and sometimes it is accompanied by hepatocellular carcinoma. Non-alcoholic fatty liver disease is likely to be associated with increased cardiovascular disease risk, and it raises the possibility that non-alcoholic fatty liver disease may be not only a marker but also an early mediator of atherosclerosis. Therapy is currently directed at treating components of the metabolic syndrome which may be beneficial also for the liver.

Hepatic steatosis (fatty liver) is increasingly recognized as a major component of the metabolic (insulin resistance) syndrome. It can progress to cirrhosis and hepatocellular carcinoma, leading to liver-related mortality. Increasing evidence shows a significant association between hepatic steatosis and hypertension; both are linked to the metabolic syndrome. This review discusses the evidence to support this association, and reviews the diagnosis and management of hepatic steatosis.

We describe the anesthetic management in a 56-year old man with hepatocellular carcinoma and cirrhosis who underwent liver transplantation (LT). Pretransplantation workup showed a 3-cm wide by 10-cm long infrarenal abdominal aortic aneurysm (AAA) with chronic dissection. He subsequently underwent living donor LT. The total operative time was 12 hours. The systolic blood pressure was maintained at normal levels. Severe hypertension was not noted. Hypotension noted during the anhepatic phase was managed with increased volume infusion and small doses (0.1 mg) of intravenous phenylephrine. Metabolic acidosis and ionized hypocalcemia were corrected accordingly. Total blood loss was 460 mL. Blood or blood products were not given. The intravascular volume was replaced with 1400 mL of 5% albumin and 10,610 mL of crystalloid. Extubation was performed in the intensive care unit at 12 hours after the operation. The postoperative course was unremarkable. The patient is alive at 3 years after LT. Patients with AAA undergoing LT present a challenge to the anesthesiologist because among the risk factors for rupture, blood pressure is the only factor under his or her control during the operation. If blood loss can be kept to a minimum and hemodynamic stability achieved, a chronically small dissected AAA may not be a contraindication to LT.

Excessive weight gain, hypertension, hyperlipidemia, and diabetes are frequently observed in patients having undergone liver transplantation (LTx). These alterations are probably multifactorial in origin, and cluster to generate a metabolic syndrome (MS), increasing the risk of cardiovascular events. We assessed the prevalence of MS (National Cholesterol Education Program-Adult Treatment Panel III criteria) in 296 LTx patients in the course of regular follow-up, at least 6 months after transplantation (median, 38 months). Several pre-LTx and post-LTx data were collected to identify the factors associated with the presence of MS. In a subset of 99 patients, insulin resistance was measured by the homeostasis model assessment. High blood pressure was present in 53% of cases, hyperlipidemia in 51%, high glucose in 37%, and enlarged waist circumference in 32%. Overall, MS (defined as 3 or more of the above features) was present in 44.5% of cases. Insulin resistance (homeostasis model assessment > 2.7) was observed in 41% of cases. Hypertension and hyperlipidemia were more frequent in subjects on cyclosporine than in tacrolimus-treated cases, whereas the type of immunosuppressive drug had no effect on the prevalence of diabetes, enlarged waist, and MS. In a logistic regression analysis, only pre-LTx body mass index (odds ratio, 1.20), body mass index increase (odds ratio, 1.18), and pre-LTx diabetes (odds ratio, 2.36) predicted MS; age, gender, etiology of liver disease, time from LTx, type of immunosuppressive drug, and previous hepatocellular carcinoma were removed from the model. Disorders related to MS are frequent in LTx patients, and are related to both pre-LTx conditions and to weight gain. Weight control is mandatory in LTx patients to prevent risk factors of premature atherosclerosis.

Adipose tissue is a massive source of bioactive substances known as adipocytokines, including tumor necrosis factor (TNF)-alpha, resistin, leptin, and adiponectin. Recent advances in medical research view obesity as a chronic low-grade inflammatory state. Hypertrophied adipocytes in obesity release chemokines that induce macrophage accumulation in adipose tissue. Accumulated macrophages in obese adipose tissue produce proinflammatory cytokines and nitric oxide, and these inflammatory changes induce adipocytokine dysregulation. The latter is characterized by a decrease in insulinsensitizing and anti-inflammatory adipocytokines, and an increase in proinflammatory adipocytokines. Adipocytokine dysregulation induces obesity-related metabolic disorders, the so-called metabolic syndrome. Metabolic syndrome is a cluster of metabolic abnormalities, including diabetes mellitus, hypertension, hyperlipidemia, and nonalcoholic steatohepatitis (NASH). Recent studies have revealed that obesity is an independent risk factor for chronic liver diseases, such as NASH, alcoholic liver disease, chronic hepatitis C, and hepatocellular carcinoma. A common mechanism underlying these hepatic clinical states is thought to be adipocytokine dysregulation. In this review, we discuss the association of adipocytokines, especially leptin, adiponectin, TNF-alpha, and resistin, with liver diseases.

Non-alcoholic fatty liver disease includes a broad spectrum of liver abnormalities ranging from simple steatosis to non-alcoholic steatohepatitis (NASH), which can progress to cirrhosis and hepatocellular carcinoma. Patients with primary NASH have the metabolic (or insulin resistance) syndrome, condition typically associated with obesity, diabetes, hyperlipidemia and hypertension. To understand the mechanisms implicated in development of NASH, animal models of non-alcoholic fatty liver disease have been generated. These have greatly improved our understanding of some of the aspects of this disease. The challenge now is to identify the common mechanisms between the animal models and humans, which could eventually lead to a better prognosis and development of novel therapeutic strategies.
