54 We need stronger evidence that maintained viral suppression through effective treatment reduces or eliminates the risk of HCC. These studies will be very hard to do now that so many more effective antivirals have come onto the market. Chronic infection with hepatitis B and/or C is the main risk factor for hepatocellular cancer, whose rates are rising both in the United States and in Canada (Figs. 5 and 6).55 A randomized study of HCC screening

versus none would be unethical. The best data we have are from patient-monitored HCC who were compliant or who refused with US follow-up.56 But, unless chronic infection with either hepatitis B or C is identified early, infected individuals will needlessly die as a consequence http://www.selleckchem.com/products/azd-1208.html of their infection. We must encourage and support appropriate public-health screening programs. Those with progression of hepatic fibrosis caused by underlying nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) may be the most appropriate

candidates for antifibrotic therapies. As the cellular mechanisms for the induction of fibrosis become better understood, treatment with specific biologics could be feasible.57 We first require access to both sensitive and reliable screening tools to identify suitable candidates for such therapies. At present, few recognize the risk of hepatic fibrosis in both children and adults who are obese.58 The outcome of PBC appears to have improved greatly over the last 20 years—likely selleck compound a result of a combination of earlier diagnosis and treatment with UDCA. Although we do not know the severity of disease at diagnosis of either PBC or PSC, a drop in the need for liver replacement for PBC is evident; sadly, this is not the case for PSC,59 a disease that often affects young males. The number of

RCTs for those with biliary disease over the last 20 years clearly indicates that minimal attention has been given to chronic biliary disease (see Fig. 7). At present, we have nothing to offer Adenosine those whom we know to have PSC, so one can question the appropriateness of radiologic screening with magnetic resonance imaging for those at high risk. The genetic profile of PBC indicates that a specific immunoregularity pathway is affected60; these findings may encourage the development of agents that specifically interfere with the “genetic” basis for this disease. Recent data report on some genetic profiles specific to PSC.61 Could a new focus for therapy be targeted biologics? There has been a worldwide escalation in healthcare costs, and restrictions in spending as a result of the current state of the world’s economy are anticipated. Perhaps, first, we need to know the origin of the cost and patterns of mortality to establish whether a redistribution of budgets would be appropriate.
