Chronic hepatitis C virus (HCV) infection is generally a slowly progressive disease. A minority of infected patients, however, eventually will develop cirrhosis and its life-threatening complications.Recent development of combination interferon (IFN) and ribavirin(RBV) antiviral therapy has changed the approach to patients infected with the virus. Once cirrhosis develops, treatment is a difficult task and should be done with close monitoring because of numerous adverse effects. In patients with compensated cirrhosis,combination therapy is the most efficient approach and offers the highest sustained virological response. Although data are limited,no significant differences have been reported between the use of pegylated interferon (PEG-IFN) and standard IFN in combination with RBV. Moreover, PEG-IFN has a higher risk of hematological complications, and this should be considered when using in advanced disease. Antiviral therapy for patients with decompensated cirrhosis should be used only in a clinical trial setting because of reported severe adverse effects. After liver transplantation, combination therapy may be an alternative for a limited number of patients. Although definitive recommendations cannot be made because of limited studies, there is a group of very well compensated patients with HCV and cirrhosis who benefited from treatment by clinicians well versed in the use of combination therapy.

The present organ donor crisis has led to accepted use of organs from donors infected with hepatitis C virus (HCV) and hepatitis B virus (HBV). Although capable of transmitting disease, these grafts offer opportunities to expand the donor pool for certain populations. Anti-HBc positive grafts can be used if care is taken to provide prophylaxis. Good quality grafts from HCV+ donors may be used in recipients who are themselves HCV+ with good outcomes.

1. Liver grafts from hepatitis C virus (HCV)-infected deceased donors can be used safely in HCV-infected recipients. 2. Histological assessment of the graft before orthotopic liver transplantation (OLT) is advised. 3. Recipients of these grafts should give consent accordingly. 4. The course of HCV disease after OLT parallels that in patients who received noninfected organs.

Background. The dynamics of hepatitis C virus (HCV) quasi species in the E2 region may correlate with the course of infection after orthotopic liver transplantation (OLT).Methods. Thirty-four patients who underwent transplantation for HCV-related cirrhosis were studied. Serum and liver samples were available before OLT and at 1 week, 4 months, and 1 year after OLT. Patients were divided into group 1 (Knodell/Ishak fibrosis stage [FS] at 1 year

Background: Wilson's disease, heralded by severe hepatic insufficiency, is a rare disorder for which emergency liver transplantation is considered to be the only effective therapy. Aims: To report the features of Wilson's disease with severe hepatic insufficiency in a series of 17 patients and, during the second period of the study, to assess the efficacy of a policy consisting of early administration of D-penicillamine. Patients: Seventeen consecutive patients with Wilson's disease were studied. During the first period of the study (up to 1979), none of the patients received D-penicillamine. During the second period (after 1979), all patients without encephalopathy at admission received D-penicillamine. Results: The four patients observed during the first period who did not have encephalopathy at admission and did not receive D-penicillamine progressed to encephalopathy and died. Among the 13 consecutive patients observed during the second period, two patients with encephalopathy at admission did not receive D-penicillamine and were transplanted. The 11 remaining patients all received D-penicillamine. Ten of these patients survived without the need for transplantation and returned to compensated liver disease without liver insufficiency. In one patient, liver insufficiency progressed and transplantation had to be performed. Conclusions: In most patients with Wilson's disease heralded by severe hepatic insufficiency and without encephalopathy at admission, early administration of D-penicillamine was associated with survival without transplantation. These results suggest the importance of early diagnosis of this form of Wilson's disease before the onset of encephalopathy, and favour early administration of D-penicillamine which could avoid the need for transplantation in most cases.

Nowadays, the number of cases in which malignant colorectal polyps are removed is increasing due to colorectal cancer screening programmes. Cancerous polyps are classified into non-invasive high grade neoplasia (NHGN), when the cancer has not reached the muscularis mucosa, and malignant polyps, classed as T1, when they have invaded the submucosa. NHGN is considered cured with polypectomy, while the prognosis for malignant polyps depends on various morphological and histological factors. The prognostic factors include, sessile or pedunculated morphology of the polyp, whether partial or en bloc resection is carried out, the degree of differentiation of the carcinoma, vascular or lymphatic involvement, and whether the polypectomy resection margin is tumor free. A malignant polyp at T1 is considered cured with polypectomy if it is a pedunculated polyp (Ip of the Paris classification), it has been completely resected, it is not poorly differentiated, the resection edge is not affected by the tumor and there is no vascular or lymphatic involvement. The sessile malignant polyp (Is of the Paris classification) at T1 is considered not cured with polypectomy. Only in some cases (e.g. older people with high surgical risk) local excision (polypectomy or endoscopic submucosal dissection or conventional endoscopic mucosal resection) is considered the definitive treatment.
