“…In various studies including a large prospective study, patients with HCV-related liver disease with a regular coffee consumption show a lower rate of disease progression such as hepatic fibrosis [131][132][133] and HCC [134][135][136][137][138] . Recently, it was also reported that more than 3 cups per day coffee drinkers are three times more likely to have a virological response to peginterferon plus ribavirin treatment than non-drinkers [139] .…”

Increased insulin resistance is frequently associated with chronic liver disease and is a pathophysiological feature of hepatogenous diabetes. Distinctive factors including hepatic parenchymal cell damage, portalsystemic shunting and hepatitis C virus are responsible for the development of hepatogenous insulin resistance/ diabetes. Although it remains unclear whether insulin secretion from pancreatic beta cells is impaired as it is in type 2 diabetes, retinopathic and cardiovascular risk is low and major causes of death in cirrhotic patients with diabetes are liver failure, hepatocellular carcinoma and gastrointestinal hemorrhage. Hemoglobin A1c is an inaccurate marker for the assessment and management of hepatogenous diabetes. Moreover, exogenous insulin or sulfonylureas may be harmful because these agents may promote hepatocarcinogenesis. Thus, pathogenesis, cause of death, assessment and therapeutic strategy for hepatogenous insulin resistance/diabetes differ from those for lifestyle-related type 2 diabetes. In this article, we review features of insulin resistance in relationship to chronic liver disease. We also discuss the impact of anti-diabetic agents on interferon treatment and hepatocarcinogenesis.

“…4 In the Japan Public Health Center-Based Prospective Study Cohort II, which included 18,815 subjects followed for 13 years and 110 incident cases of liver cancer affected by HCV or hepatitis B virus (HBV), the RRs were 0.67 for fewer than one cup per day, 0.49 for one to two cups, and 0.54 for three or more cups of coffee per day. 5 We computed the summary RRs and the corresponding CIs for coffee drinkers, and for various levels of coffee consumption versus nondrinkers, applying the same methods of the previous metaanalysis. 1 Briefly, we performed a Medline search of the literature from 1966 to June 2009, using the MeSH terms "coffee" and combinations of "hepatocellular" or "liver" and "carcinoma" or "neoplasm."…”

accurately distinguish them before the determination of therapy (i.e., liver transplantation). Our data show that the application of the American Association for the Study of Liver Diseases guidelines prevents a false-positive diagnosis of ICC in cirrhosis. Small ICC may display an early enhancement (partial or total) in the arterial phase. This is similar to the HCC pattern, but because we have not observed washout in delayed phases, this finding is confirmed to be specific for HCC 2,3 and critical for nodule diagnosis.We focused our analysis on ICC arising within a cirrhotic liver; this constituted most of the cases detected in the setting of a surveillance program for early HCC diagnosis. The majority of the published series evaluating the computed tomography and magnetic resonance imaging features of ICC did not restrict the analysis to only patients with cirrhosis, and most of the cases were detected in the presence of symptoms, so the lesions usually were larger. We already acknowledged in the discussion that the number of patients recruited was limited, but even so, this is the largest cohort of ICC in cirrhosis. More importantly, more than two-thirds of the nodules were smaller than 3 cm, and the challenge of imaging characterization lies in small nodules.Regarding the previously reported delayed washout in ICC, 4 we have to stress again that the reported "washout" of ICC cannot be confused with the typical washout of HCC in delayed phases. The former still enhances more than the hepatic parenchyma, whereas the latter typically has lower enhancement in delayed phases with respect to the liver.In conclusion, our data show that small ICC may mimic the pattern of HCC in the arterial phases of magnetic resonance imaging, but this tumor does not show washout in the delayed venous phase. This is specific for HCC and may allow a noninvasive HCC diagnosis, but if it is not observed, diagnostic biopsy should be mandatory, as already recommended in the American Association for the Study of Liver Diseases guidelines. We reviewed in a meta-analysis data from six case-control and four cohort studies on coffee and hepatocellular carcinoma (HCC) published between 1966 and February 2007. 1 The summary relative risk (RR) estimate for coffee drinkers versus nondrinkers was 0.59 (0.54 from case-control and 0.64 from cohort studies). The RR was 0.42 (95% confidence interval [CI]: 0.32-0.55) for drinkers of three or more cups per day, but this estimate was based on limited data from case-control studies, mainly coming from Southern Europe.Since then, four prospective studies were published, including a total of 473 cases of HCC. A nested case-control study, conducted as part of the Japanese Collaborative Cohort Study for Evaluation of Cancer Risk, and reporting information on 106 HCC cases out of 110,792 subjects followed for 11 years, found a RR of 0.49 for daily coffee drinkers versus nondrinkers, 0.31 in hepatitis C virus (HCV)-positive subjects and 0.75 in HCV-negative subjects. 2 A Finnish prospective study of 60,323 su...
