Halting the haematochezia.

An elderly gentleman with primary sclerosing cholangitis (PSC) was admitted with rectal bleeding, shown on flexible sigmoidoscopy to be arising from rectal varices, which bled despite endoscopic therapy with histoacryl glue. Therapeutic options were limited with surgery and transjugular intrahepatic portosystemic shunt deemed too high risk, and endovascular embolisation through interventional radiology was sought. Coil-assisted retrograde transvenous obliteration was used to good effect.

Hepatic encephalopathy: current challenges and future prospects.

Hepatic encephalopathy (HE) is a common complication of liver dysfunction, including acute liver failure and liver cirrhosis. HE presents as a spectrum of neuropsychiatric symptoms ranging from subtle fluctuating cognitive impairment to coma. It is a significant contributor of morbidity in patients with liver disease.

Asterixis.

Adams and Foley described asterixis in the 1940s in patients with hepatic encephalopathy, but it has since been associated with a wide range of potential causes, both in neurology and general medicine. Here, we review the history, characteristics and clinical significance of this important clinical sign.

Digital image analysis of liver collagen predicts clinical outcome of recurrent hepatitis C virus 1 year after liver transplantation.

Clinical outcomes of recurrent hepatitis C virus after liver transplantation are difficult to predict. We evaluated collagen proportionate area (CPA), a quantitative histological index, at 1 year with respect to the first episode of clinical decompensation. Patients with biopsies at 1 year after liver transplantation were evaluated by Ishak stage/grade, and biopsy samples stained with Sirius red for digital image analysis were evaluated for CPA.

The importance of steatosis in chronic hepatitis C infection and its management: A review.

Hepatitis C virus (HCV) infection is a major cause of chronic liver disease with approximately 180 million people infected worldwide. Hepatic steatosis is a frequent histological finding in chronic hepatitis C (CHC) infection and is 2- to 3-fold more common than would be expected by chance alone. A high body mass index with excess visceral fat distribution is associated with steatosis in patients infected with HCV genotype 1 but not genotype 3, re-enforcing the concept that in patients with CHC, some have "metabolic steatosis", predominantly HCV genotype 1, and others "viral steatosis", mainly HCV genotype 3.

King's Score: an accurate marker of cirrhosis in chronic hepatitis C.

Objectives: Histological assessment of patients with chronic hepatitis C infection is no longer performed routinely; consequently, a simple test is needed to identify patients with significant hepatic fibrosis.

Methods: Data were collected, retrospectively, on 923 consecutive patients undergoing percutaneous liver biopsy for chronic hepatitis C at King's College Hospital between 1 January 2000 and 30 June 2006; 602 patients were accepted to form the training set and a further 105 patients to form the validation set.

Results: On liver biopsy, 132 (22%) had cirrhosis (Ishak F5-6) in the training set and 19 (18%) in the validation set.

The increasing prevalence of hepatitis delta virus (HDV) infection in South London.

On the basis of historical studies, hepatitis delta virus (HDV) infection is considered uncommon in the United Kingdom (UK) and mainly confined to intravenous drug users. In order to assess the current prevalence of HDV co-infection in patients with chronic hepatitis B (HBV), a retrospective analysis was performed of 962 consecutive HBV-infected adult patients referred to King's College Hospital between January 1st 2000 and March 31st 2006. The 82 subjects positive for HDV antibody (8.

Liver transplantation in patients over 60 and 65 years: an evaluation of long-term outcomes and survival.

With increased demand for liver transplantation (LT), outcomes of older recipients have been subjected to greater scrutiny, as previous studies have demonstrated poorer survival outcomes. Outcomes of 77 patients aged>65 yr (group 1) who underwent transplantation between 1988 and 2003 at King's College Hospital, London, were compared with all recipients aged between 60 and 64 yr (group 2, n=137) and 202 time-matched control patients with chronic liver disease aged between 18-59 yr (group 3). Patient survival at 30-days for groups 1, 2, and 3 were 99%, 94%, and 94%, respectively (P=not significant [NS]).

Hepatic dysfunction in sickle cell disease: a new system of classification based on global assessment.

Background & Aims: Hepatic dysfunction in adults with sickle cell disease varies in character and severity from self-limited cholestasis to life-threatening acute liver failure and cirrhosis. Because previous attempts to describe patterns of liver disease have not reflected clinical experience, we aimed to characterize the presentation, clinicopathologic findings, and natural history of such patients.

Methods: We reviewed the clinical, laboratory, radiographic, and histologic features with the natural history of 38 patients (mean age, 33 years) with Hb SS, SC, or S-beta thalassemia referred to a tertiary liver center for assessment.

Actin-free Gc globulin: a rapidly assessed biomarker of organ dysfunction in acute liver failure and cirrhosis.

Reductions in serum levels of Gc globulin, a hepatically synthesized component of the extracellular actin scavenger system responsible for complexing circulating actin and attenuating intravascular microthrombus formation, are associated with poor outcome in acute liver failure. Clinically applicable assays of the important actin-free fraction (Af-Gc) have not been available until now. We measured actin-free Gc globulin levels with a novel, rapid assay in 61 cases of acute liver failure (ALF) and in 91 patients with cirrhosis (40 of whom were clinically unstable with extrahepatic organ dysfunction), and studied associations with liver dysfunction, extrahepatic organ dysfunction, indices of disseminated coagulation, and outcome.

Sickle liver disease--an unusual presentation in a compound heterozygote for HbS and a novel beta-thalassemia mutation.

A 38-year-old Ghanaian man presented with a 6-month history of worsening pruritus, jaundice, and ascites. He was previously fit and well and rarely drank alcohol. Screening tests for chronic liver disease including viral, autoimmune, and other metabolic causes including iron overload were unremarkable.
