A case report is presented of a 43-year-old woman with generalized peliosis hepatitis that developed during longterm use of oral contraceptives (OCs). The patient had been in good health until the last 2 years when she began to experience vague epigastric pains and a feeling of abdominal distension. Several months prior to admission, she had started to complain of itching and fatigue. There was no history of dark urine, white stools, or hepatitis. On physical examination, no jaundice or cutaneous stigmata of chronic liver disease were observed. Laboratory studies showed a normal erythrocyte sedimentation rate and hematological blood count. A radionuclide study of the liver showed hepatomegaly; especially the left lobe was enlarged. A computerized tomographic scan of the liver showed multiple areas of decreased density in both of the enlarged lobes. There was no evidence of a tumor. Selective transfemoral angiography of the celiac artery also showed hepatic enlargement but no signs of a space-occupying lesion. At laparoscopy, the liver was grossly enlarged and had a lumpy appearance, but again there were no signs of a tumor. No evidence of veno-occlusive disease or hepatocellular adenoma was found. The diagnosis was peliosis hepatitis. The OCs were withdrawn, and the patient was discharged. Regular follow-up in the outpatient department showed no decrease in the size of the liver. The alkaline phosphatase level rose. The fatigue became worse, and cholestyramine was prescribed for progressive itching. In September 1980, the patient was admitted for reevaluation. A repeated CT scan and angiography of the liver again yielded no evidence of a tumor. Esophagoscopy showed the presence of varices grade 2. The liver at laparoscopy had the same appearance as it had in 1976. Histological examination of a biopsy specimen showed occasional dilated sinusoids and locally marked periportal and intralobular fibrosis. No regeneration nodules were found. The diagnosis was liver fibrosis. The patient's condition deteriorated gradually in the following years. She experienced increasing fatigue. Steatorrhea developed, and the patient lost weight. She needed increasing doses of cholestyramine and oral supplementation of vitamins A, D, and K. She was admitted for a 3rd time in February 1985. Esophagoscopy revealed varices grade 4. A CT scan of the liver showed no change. The patient successfully underwent an orthotopic liver transplantation in January 1987. The diagnosis of peliosis hepatis was well documented in this patient.

A case of septicemia due to Aeromonas hydrophila (A. hydrophila) in a 54-year-old male suffering from progressive severe jaundice and fatigue is reported. The patient developed multiple organ failure despite aggressive therapy including plasma exchange and glucose-insulin therapy. Upon admission to our hospital, therapy was started with ampicillin (ABPC) 4 g/day, gentamicin (GM) 120 mg/day, hemodialysis, continuous hemofiltration, catecholamines and a respirator, but he expired on the 2nd hospital day. Blood culture and histology revealed A. hydrophila. Postmortem examination showed alcoholic liver fibrosis which was most likely liver cirrhosis. In the literature, patients with septicemia due to Aeromonas had underlying hepatic cirrhosis more often than did those with septicemia due to other gram-negative bacilli. Therefore, it is important-to consider the possibility of liver cirrhosis in patients with A. hydrophila septicemia.

Genetic hemochromatosis is an autosomal recessive disease, characterized by an increased iron absorption, leading to progressive iron overload. The fully expressed phenotype comprises fatigue, skin pigmentation, liver disease with hepatomegaly, cirrhosis and hepatocellular carcinoma, and diabetes. Arthralgias are frequent, cardiopathy or impotence may occur. This presentation is now unfrequent with earlier diagnosis, and patients are often asymptomatic--with only biochemical expression--or pauci-symptomatic (mild fatigue, arthralgias or increased transaminases). Transferrin saturation is always increased. Serum ferritin is proportional to iron burden. Diagnosis is now easy, since most patients are homozygote for the C282Y mutation of the HFE gene. Liver biopsy can be useful to quantify iron overload and assess liver fibrosis. The disease can be lethal due to liver disease, carcinoma or heart disease, but life expectancy goes to normal if patients are treated before the occurrence of cirrhosis. Treatment relies on regular venesections. Familial screening is essential.

Chronic hepatitis C virus (HCV) infection affects 170 million individuals worldwide. These individuals are at risk of developing both hepatological and non-hepatological manifestations. HCV is usually only fatal when it leads to cirrhosis, the final stage of liver fibrosis. Therefore, an estimate of fibrosis progression represents an important surrogate end-point for the evaluation of the vulnerability of an individual patient. In untreated patients, the median expected time to cirrhosis is 30 years; 33% of patients have an expected median time to cirrhosis of less than 20 years and 31% will only progress to cirrhosis after more than 50 years, if ever. Several factors are associated with fibrosis progression rate: duration of infection, age, male gender, consumption of alcohol, HIV co-infection and low CD4 count. Non-hepatological manifestations are frequent with more than 70% of HCV patients experiencing fatigue or at least one extrahepatic clinical manifestation involving primarily the joints, skin and muscles. Several immunological abnormalities are frequently observed, including cryoglobulins (40%),anti-nuclear antibodies (10%) and anti-smooth muscle antibodies (7%). In contrast severe extrahepatic manifestations are rare, with 1% for systemic vasculitis.

Hepatitis C virus (HCV) infection is a major public-health-care problem, with over 170 million infected worldwide. Patients with chronic HCV infection often complain of various cognitive problems as well as symptoms of depression, anxiety, and fatigue. Relatively little is known, however, about the specific cognitive deficits that are common among HCV patients, and the influence of psychiatric symptomatology on cognitive functioning. In the current study of 21 chronically infected HCV patients, we assessed subjective cognitive dysfunction, depression, anxiety, and fatigue and compared these symptom areas to cognitive tests assessing visuoconstruction, learning, memory, visual attention, psychomotor speed, and mental flexibility. Results revealed that cognitive impairment ranged from 9% of patients on a visuoconstruction task to 38% of patients on a measure of complex attention, visual scanning and tracking, and psychomotor speed, and greater HCV disease severity as indicated by liver fibrosis was associated with greater cognitive dysfunction. Objective cognitive impairment was not related to subjective cognitive complaints or psychiatric symptomatology. These findings suggest that a significant portion of patients with chronic HCV experience cognitive difficulties that may interfere with activities of daily living and quality of life. Future research using cognitive measures with HCV-infected patients may assist researchers in identifying if there is a direct effect of HCV infection on the brain and which patients may be more likely to progress to cirrhosis and hepatic encephalopathy.

Schistosomiasis is caused by trematode parasites of one of five species, Schistosoma mansoni, Schistosoma haematobium, Schistosoma japonicum, Schistosoma intercalatum, or Schistosoma mekongi, acquired via skin contact with fresh water containing infectious larval cercariae. Between 1 and 8 weeks after exposure, acute schistosomiasis presents as dermatitis, fever, fatigue, or eosinophilia. If untreated, long-term infection may cause anemia or undernutrition and may progress to liver fibrosis, portal hypertension, or hydronephrosis. Schistosomiasis represents a threat to residents and visitors in all endemic areas of Africa, Asia, and South America. Travelers should be made aware of infection risk if they become exposed to untreated fresh water. New immigrants and those returning to high-risk areas to visit friends and family should be screened for signs and symptoms of acute and chronic schistosomiasis. Physicians caring for travelers and immigrants must be familiar with the signs and symptoms of schistosomiasis and must be able to diagnose and treat it correctly.

Primary biliary cirrhosis (PBC) is a chronic, autoimmune, cholestatic liver disease. It is characterized by slow destruction of small intrahepatic bile ducts, impaired biliary secretion and stasis of toxic endogenous bile acids within the liver with progression to liver fibrosis and cirrhosis. It has an increasing prevalence worldwide. It occurs more commonly in women than men at a ratio of 10:1. In most cases, diagnosis relies on a positive antimitochondrial antibody in the context of chronic cholestasis, without the need for a liver biopsy. Ursodeoxycholic acid improves survival even in patients with advanced liver disease. Certain findings such as fatigue, anti-nuclear antibodies, anti-centromere antibodies and the GP210 antinuclear antibody predict a poor outcome. Up to 40% of patients do not respond satisfactorily to ursodeoxycholic acid therapy and should be considered for adjunctive therapies. Several adjunctive and newer therapies are being tested and some appear promising. We provide a review of PBC with a focus on advances in therapies that may impact the management of PBC in the near future.

Hepatitis C virus (HCV) infection is associated with fatigue, depression, and cognitive impairment even in the absence of severe liver fibrosis or cirrhosis. HCV has been hypothesised to cause neurodegenerative changes through low-grade neuroinflammation. Our aim was to examine whether cortical thickness (CTh) differs between chronic HCV patients and healthy controls, suggestive of cortical atrophy. In this case-control study 43 HCV patients without severe liver fibrosis, substance abuse, or comorbid HIV or hepatitis B virus infection, and 43 age and sex matched controls underwent MRI. Cortical thickness was measured using a surface based approach. Participants underwent semi-structured psychiatric interview and fatigue was assessed using the fatigue severity scale. HCV was associated with higher fatigue scores, and 58 % of HCV patients suffered from significant fatigue (p < 0.0001). Depression was observed in 16 % of patients. Areas of significantly reduced CTh were found in both left and right occipital cortex and in the left frontal lobe after correction for multiple comparisons (p < 0.05). No association between fatigue, former substance abuse, or psychotropic medication and CTh was found. No overall difference in cerebral white and grey matter volume was found. The findings support the hypothesis that HCV is associated with neurodegenerative changes.

Since its identification in 1989, hepatitis C virus (HCV) has emerged as a worldwide health problem with roughly 185 million chronic infections, representing individuals at high risk of developing cirrhosis and liver cancer. In addition to being a frequent cause of morbidity and mortality due to liver disease, HCV has emerged as an important trigger of lymphoproliferative disorders, owing to its lymphotropism, and of a wide spectrum of extra-hepatic manifestations (HCV-EHMs) affecting different organ systems. The most frequently observed HCV-EHMs include mixed cryoglobulinemia and cryoglobulinemic vasculitis, B-cell non-Hodgkin's lymphoma, nephropathies, thyreopathies, type 2 diabetes mellitus, cardiovascular diseases, and several neurological conditions. In addition, neuropsychiatric disorders and neurocognitive dysfunction are reported in nearly 50% of patients with chronic HCV infection, which are independent of the severity of liver disease or HCV replication rates. Fatigue, sleep disturbance, depression and reduced quality of life are commonly associated with neurocognitive alterations in patients with non-cirrhotic chronic HCV infection, regardless of the stage of liver fibrosis and the infecting genotype. These manifestations, which are the topic of this review, typically occur in the absence of structural brain damage or signal abnormalities on conventional brain magnetic resonance imaging (MRI), although metabolic and microstructural changes can be detected by in vivo proton magnetic resonance spectroscopy, perfusion-weighted and diffusion tensor MRI, and neurophysiological tests of cognitive processing. Several lines of evidence, including comparative and longitudinal neuropsychological assessments in patients achieving spontaneous or treatment-induced viral clearance, support a major pathogenic role for HCV in neuropsychiatric and neurocognitive disorders.

Hepatitis E has long been thought of as an infection confined to the developing world. However, there has been an increased incidence of locally acquired cases in developed countries especially in transplant patients. Our first case is a 56-year-old Caucasian female post-heart transplant patient who presented with diarrhea and abdominal pain. She was found to be acutely infected with hepatitis E and progressed to stage 3 liver fibrosis. Our second patient was an otherwise healthy 76-year-old Vietnamese female who presented with abdominal pain, jaundice and fatigue. She was diagnosed with acute hepatitis E complicated by acute renal failure. There have only been a few reported cases of acute hepatitis E complicated by renal failure.
