Intrahepatic shunts are rarely diagnosed as a cause of neurocognitive abnormality. A complaint of fatigue led to the diagnosis of a right portal vein-hepatic vein aneurysmal communication in a 23-yr-old, otherwise healthy woman. Neuropsychological testing, imaging, and MR spectroscopy revealed changes similar to those described in patients with cirrhosis and subclinical hepatic encephalopathy. T1-weighted MRI showed a hyperintense globus pallidus, a feature seen in subjects with and without portal-encephalopathy. Portal-systemic shunting in the absence of parenchymal liver disease reproduces neurological features described in cirrhosis.

Hereditary hemochromatosis is the most commonly inherited autosomal recessive disorder. Hemochromatosis is a current or potential progression of abnormally high accumulations of iron in the liver. If left untreated, the condition can lead to chronic or irreversible hepatic fibrosis, cirrhosis, hepatocellular carcinoma, arthritis, and organ failure. Common signs and symptoms seen in the primary care setting include fatigue, weakness, abdominal pain, palpitations, skin pigmentation changes, and arthropathy, but any symptom associated with organ damage may be reported. Because prompt intervention can cease or reverse the debilitating effects of iron overload, prompt disease diagnosis and treatments are imperative.

The authors review their experience (1967-present) in the use of cyproterone acetate (CPA) in precocious puberty. CPA was found effective in persistently suppressing pituitary gonadotropic secretion when administered orally at a dose of 50 mg b.i.d. (70-100 mg/d). After the introduction of gonadotropic analogues (GnRHa) for treatment of central precocious puberty, short term use of CPA was found useful to counteract the initial stimulatory effect of the GnRHa as well as an adjunct drug in case of very active adrenarche causing advanced bone age during GnRHa treatment. The final heights of girls treated with CPA and girls treated with D-Trp6-LHRH were found comparable: 157.8+/-5.1 cm vs 159.6+/-6.3 cm, respectively. The main adverse effects were occasional fatigue due to partial adrenal insufficiency with CPA and gynecomastia in a few boys. Liver function tests were normal in all patients with the exception of one boy with severe hypothalamic disease, including precocious puberty, who developed liver cirrhosis 3 years after stopping CPA following 5 years treatment. Other indications for CPA treatment during childhood and adolescence, such as fast puberty, congenital adrenal hyperplasia and acne, are also mentioned.

Primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) are chronic progressive cholestatic diseases that frequently lead to biliary cirrhosis. The exact pathogenesis of these diseases remains elusive but is likely immunologically based. Complications range from fatigue and pruritus to end-stage liver disease. The risk of developing hepatocellular carcinoma is low for patients with PBC, whereas cholangiocarcinoma is common in PSC and carries an ominous prognosis. Although ursodeoxycholic acid is effective in slowing the progression of PBC, no effective medical therapy exists for PSC. Liver transplantation is the only option for patients with end-stage liver disease and yields excellent long-term survival in both groups.

A 55-year-old Turkish man with a history of chronic hepatitis B for 35 years, presented with incapacitating fatigue and worsening shortness of breath. He was hospitalized several times because of hepatic encephalopathy. He underwent liver transplantation for a clinical diagnosis of Child's C cirrhosis complicated by hepatopulmonary syndrome. The explanted liver, however, was not cirrhotic and demonstrated features of hepatoportal sclerosis. Although treatment for hepatoportal sclerosis is relief of portal hypertension; in rare cases such as in this patient with liver failure, liver transplantation is indicated.

End-stage liver disease due to chronic hepatitis C is the leading indication for orthotopic liver transplantation in the United States. Twenty percent to 30% of hepatitis C patients are at increased risk of developing cirrhosis, and 1% to 4% of cirrhotic patients will develop hepatocellular carcinoma. These findings warrant treatment for hepatitis C virus (HCV)-infected patients. Currently, the mainstay in treatment of HCV is the use of recombinant alpha interferon, or its equivalent, in combination with the oral antiviral agent ribavirin. The major goals of therapy are clearance of the virus, achieving a noninfectious state, and halting the necro-inflammatory process that leads to fibrosis and progression to cirrhosis. End of treatment response (ETR) is biochemical and virological remission-- normalization of serum aminotransferase (ALT) and undetectable levels of HCV RNA, at the end of therapy. Sustained virological response (SVR) is defined as the absence of viremia and persistently normal aminotransferase 6 months off treatment, and is the ultimate goal of therapy. Patients who achieve SVR will have significant and persistent histologic improvement. HCV genotype, pretreatment levels of HCV-RNA (viral load), the presence of advanced fibrosis or cirrhosis, gender, and age are independent predictors of response. Ribavirin is teratogenic, therefore, contraception is mandatory for both males and females during and up to 6 months after therapy. Side effects of combination therapy are dose-dependent and most commonly include symptoms of irritability, depression and fatigue, and laboratory evidences of leukopenia, thrombocytopenia, and hemolytic anemia.

A successful case with liver cirrhosis underwent re-tricuspid valve replacement (TVR) using right heart bypass is reported herein. A 59-year-old lady previously undergone tricuspid valve replacement with bioprosthetic valve had suffered from exertional fatigue as the feature of congestive heart failure. She also presented severe liver dysfunction owing to chronic hepatitis and cardiac liver cirrhosis. She was diagnosed with structural deterioration of bioprosthesis in tricuspid position. She underwent re-TVR with right heart bypass consisted of centrifugal pump, heparin coating circuit and blood reservoir. This system lacked of membranous oxygenator in order not to activate various kinds of chemical mediator which leads to postoperative liver dysfunction. Postoperative course was uneventful and she is doing well 1 year after the operation. Although the mortality of the TVR in the patient with cirrhosis remains still high, this new technique seems to provide better outcome in this kind of patients.

We report the case of a 66-year-old male with ulcerative colitis diagnosed in 1987, who had been treated with azathioprine (AZA) for the past two years (average dose about 1.6 mg/kg/day). In May 1999 he presented with painless jaundice, fatigue and recent weight loss. Cholestatic enzymes were elevated, alpha-fetoprotein was normal and hepatitis B/C serology negative. After diagnosis of veno-occlusive disease (VOD) and hepatocellular carcinoma (HCC) via biopsy, tumour resection was performed. The histology was typical for a well-differentiated HCC with trabecular and pseudoglandular structures. Neighbouring liver tissue was atrophic, with nodular regenerative hyperplasia (NRH), peliosis-like sinusoidal ectasias and intra-sinusoidal accumulation of blood, associated with peri-sinusoidal fibrosis. Although none of the well-established risk factors for HCC such as cirrhosis, hepatitis B/C, metabolic liver disease or toxins were present, this patient developed HCC. This and previous reports suggest that NRH and/or VOD associated with AZA represent a risk factor for HCC. AZA should therefore not only be stopped in patients with NRH/VOD but patients should also be screened for HCC.

Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease that predominantly affects middle-aged women; fatigue and pruritus are the most common symptoms at presentation. Liver function tests are consistent with cholestasis and reveal an elevation of serum alkaline phosphatase and gamma-glutamyl transpeptidase with or without elevation of aminotransferase levels. Histologically, PBC is characterized by the destruction of the intrahepatic small bile ducts and subsequently fibrosis. The serological hallmark of the disease is the presence of antimitochondrial antibodies, which are found in 95% of patients with PBC. The antimitochondrial antibodies are directed against the 2-oxo-acid dehydrogenase complexes located on the inner membrane of the mitochondria. PBC generally slowly progresses, even over decades, and may lead to liver failure. In symptomatic patients, advanced age, elevated serum bilirubin levels, decreased serum albumin levels, and cirrhosis each correlate with shortened survival. Immunosuppressive and anti-inflammatory drugs have been used in the treatment of PBC based on the presumed autoimmune pathogenesis, but satisfactory agents leading to complete reversal or cure of the disease are not available. At present ursodeoxycholic acid appears to be the only effective therapy in preventing or delaying the need for liver transplantation and improving survival. However, a number of patients receiving ursodeoxycholic acid still develop progressive disease and require transplantation; transplantation is the only effective therapy at the end stage of the disease.

Patients with cirrhosis of the liver often complain of tiredness and a lack of strength at physical exercise. Other investigators have found that muscle strength, work capacity, and maximal oxygen consumption are reduced in cirrhosis. We hypothesized that mitochondrial maximal rate of ATP synthesis in skeletal muscle may be impaired in these patients. This was tested with (31)P nuclear magnetic resonance spectroscopy in anterior tibial muscle of cirrhotic patients and healthy controls at rest, during exercise, and subsequent recovery. In patients with Child-Pugh class B and C cirrhosis resting PCr/P(i) ratio (8.3 +/- 1.0; n = 7) was lower than in patients with Child-Pugh class A cirrhosis (12.1 +/- 2.1; n = 7) and controls (11. 7 +/- 1.1; n = 6; P =.03), while the resting P(i)/gammaATP ratio was higher in Child-Pugh class B and C patients (0.43, 0.30, and 0.27, respectively; P =.03). Maximal rate of mitochondrial adenosine triphosphate (ATP) synthesis (V(max)) as calculated from the initial rate of phosphocreatine (PCr) recovery after work was lower in Child-Pugh class B and C cirrhosis (0.189 mmol/L/s +/- 0.034) than in both Child-Pugh class A patients (0.402 mmol/L/s +/- 0.103) and controls (0.425 mmol/L/s +/- 0.064; P =.01). V(max) was significantly correlated to intracellular free [Mg(2+)] obtained from the (31)P nuclear magnetic resonance (NMR) spectra (P =.003). Insufficient oxygen delivery did not seem a likely cause of reduced ATP synthesis in the patients. These findings suggest either a decreased number of mitochondria in skeletal muscle of the cirrhotic patient in Child-Pugh class B and C or a defective mitochondrial function that could be related to low intracellular free [Mg(2+)].
